One main issue within environmental ethics is the so-called Demarcation Problem, i.e. the question of which entities are members of the moral community and hold intrinsic value. I argue that the demarcation problem relies mainly on Kantian moral philosophy. While the Kantian framework offers a strong and immediately deontological argument for moral agents holding inherent moral values, it presents problems when stretched beyond its original scope and lacks an adequate ground for addressing relational complexity and the moral significance of collectives. (...) In this paper I outline an alternative axiological framework ('map of moral significance') that relies on a relational ontology and encompasses intrinsic and relational values as the two equipollent axes of a matrix in which to embed the question posited by the Demarcation Problem.

Recent feminist theorizing has pointed to a `resurgent patriarchy' within neo-liberal postfeminist times, which re-orders and restabilizes the heterosexual matrix through a politics of `postfeminist masquerade' demanded of girls and women (McRobbie). This paper seeks to complicate this thesis, exploring the regulation and rupture of Butler's `heterosexual matrix' as a complex performative politics through which girls' conflictual relationships with themselves, and other girls and boys are staged and through which dominant versions of tweenage and teenage femininity are reinscribed (...) but also reworked, in race and class specific ways. Drawing on Deleuze and Guattari's powerful conceptual repertoire for disrupting Oedipal logics in Anti-Oedipus, we offer a `molecular mapping', illustrating cracks and ruptures in what is a porous heterosexual matrix, exploring a rhythm of `deterritorializations' and `reterritorializations' of the normative in our respective ethnographic and narrative interviews with girls. We also trace more sustained ruptures of heteronormative femininity drawing upon Deleuze and Guattari's notion of `lines of flight' and Braidotti's concept of `alternative figuration'. We argue ruptures and alternative figurations are not constitutive of total `molar' resistance to norms, but are significant spaces of doing girl differently and crucial to map if we are to perceive the malleability and multiplicity of contemporary girl subjectivities, which exceed heteronormative femininity and phallogocentric desire.

This article describes a method of scoping for potential ethical contentions within a resource constrained research environment where actor participation and bottom–up analysis is precluded. Instead of reverting to a top–down analytical structure, a data-led process is devised. This imitates a bottom–up analytic structure in the absence of the direct participation of actors, culminating in the construction of a map of the ethical landscape; a high-resolution ethical matrix of coded interpretations of various actors’ ethical framings of the technology. Despite (...) its limitations, which are discussed, the map can subsequently support the identification of areas where ethical contentions may be raised. Here, the method is described with reference to the construction and analysis of a map of the ethical landscape of carbon capture and storage technology. Taken as a preliminary stage of a larger study, it can support the design and initiation of more sophisticated analyses which may integrate stronger bottom–up participation and facilitate a reflective, deliberative process amongst actors.

Growth factors and the extracellular matrix provide the environmental cues that control the proliferation of most cell types. The binding of growth factors and matrix proteins to receptor tyrosine kinases and integrins, respectively, regulates several cytoplasmic signal transduction cascades, among which activation of the mitogen-activated protein kinase cascade, ras → Raf → MEK → ERK, is perhaps the best characterized. Curiously, ERK activation has been associated with both stimulation and inhibition of cell proliferation. In this review, we summarize (...) recent studies that connect ERK signaling to G1 phase cell cycle control and suggest that the cellular response to an ERK signal depends on both ERK signal intensity and duration. We also discuss studies showing that receptor tyrosine kinases and integrins differentially regulate the ERK signal in G1 phase. BioEssays 22:818–826, 2000. © 2000 John Wiley & Sons, Inc. (shrink)

This paper proposes to present a novel method of generating cryptographic dynamic substitution-boxes, which makes use of the combined effect of discrete hyperchaos mapping and algebraic group theory. Firstly, an improved 2D hyperchaotic map is proposed, which consists of better dynamical behaviour in terms of large Lyapunov exponents, excellent bifurcation, phase attractor, high entropy, and unpredictability. Secondly, a hyperchaotic key-dependent substitution-box generation process is designed, which is based on the bijectivity-preserving effect of multiplication with permutation matrix to obtain (...) satisfactory configuration of substitution-box matrix over the enormously large problem space of 256!. Lastly, the security strength of obtained S-box is further elevated through the action of proposed algebraic group structure. The standard set of performance parameters such as nonlinearity, strict avalanche criterion, bits independent criterion, differential uniformity, and linear approximation probability is quantified to assess the security and robustness of proposed S-box. The simulation and comparison results demonstrate the effectiveness of proposed method for the construction of cryptographically sound S-boxes. (shrink)

Objective: Tangent Space Mapping using the geometric structure of the covariance matrices is an effective method to recognize multiclass motor imagery. Compared with the traditional CSP method, the Riemann geometric method based on TSM takes into account the nonlinear information contained in the covariance matrix, and can extract more abundant and effective features. Moreover, the method is an unsupervised operation, which can reduce the time of feature extraction. However, EEG features induced by MI mental activities of different subjects (...) are not the same, so selection of subject-specific discriminative EEG frequency components play a vital role in the recognition of multiclass MI. In order to solve the problem, a discriminative and multi-scale filter bank tangent space mapping algorithm is proposed in this article to design the subject-specific Filter Bank so as to effectively recognize multiclass MI tasks. Methods: On the 4-class BCI competition IV-2a dataset, first, a non-parametric method of multivariate analysis of variance based on the sum of squared distances is used to select discriminative frequency bands for a subject; next, a multi-scale FB is generated according to the range of these frequency bands, and then decompose multi-channel EEG of the subject into multiple sub-bands combined with several time windows. Then TSM algorithm is used to estimate Riemannian tangent space features in each sub-band and finally a liner Support Vector Machines is used for classification. Main Results: The analysis results show that the proposed discriminative FB enhances the multi-scale TSM algorithm, improves the classification accuracy and reduces the execution time during training and testing. On the 4-class BCI competition IV-2a dataset, the average session to session classification accuracy of nine subjects reached 77.33 ± 12.3%. When the training time and the test time are similar, the average classification accuracy is 2.56% higher than the latest TSM method based on multi-scale filter bank analysis technology. When the classification accuracy is similar, the training speed is increased by more than three times, and the test speed is increased two times more. Compared with Supervised Fisher Geodesic Minimum Distance to the Mean, another new variant based on Riemann geometry classifier, the average accuracy is 3.36% higher, we also compared with the latest Deep Learning method, and the average accuracy of 10-fold cross validation improved by 2.58%. Conclusion: Research shows that the proposed DMFBTSM algorithm can improve the classification accuracy of MI tasks. Significance: Compared with the MFBTSM algorithm, the algorithm proposed in this article is expected to select frequency bands with good separability for specific subject to improve the classification accuracy of multiclass MI tasks and reduce the feature dimension to reduce training time and testing time.

The paper presents an approach to encrypt the color images using bit-level permutation and alternate logistic map. The proposed method initially segregates the color image into red, green, and blue channels, transposes the segregated channels from the pixel-plane to bit-plane, and scrambles the bit-plane matrix using Arnold cat map (ACM). Finally, the red, blue, and green channels of the scrambled image are confused and diffused by applying alternate logistic map that uses a four-dimensional Lorenz system to generate a pseudorandom (...) number sequence for the three channels. The parameters of ACM are generated with the help of Logistic-Sine map and Logistic-Tent map. The intensity values of scrambled pixels are altered by Tent-Sine map. One-dimensional and two-dimensional logistic maps are used for alternate logistic map implementation. The performance and security parameters histogram, correlation distribution, correlation coefficient, entropy, number of pixel change rate, and unified averaged changed intensity are computed to show the potential of the proposed encryption technique.

Topic of quantum chaos has begun to draw increasing attention in recent years. So, to ensure the security of digital image, an image encryption algorithm based on combining a hyperchaotic system and quantum 3D logistic map is proposed. This algorithm is applied in four stages. Initially, the key generator builds upon the foundation of mean for any row or column of the edges of the plain image. Its output value is used to yield initial conditions and parameters of the proposed (...) image encryption scheme. Next, it diffuses the plain image by the random sequences generated by 3D hyperchaotic system, and the diffusion process is realized by implementing XOR operation. Then, the diffused image and chaotic sequences are produced by the 3D quantum chaotic logistic map, expressed as a quantum superposition state using density matrix which is a representation of the state of a quantum system, and finally the resulting quantum image is then confused and diffused simultaneously by a unitary matrix generated by logistic chaos using XNOR operation to obtain the final cipher image. Because of the dependence on the plain image, the algorithm can frustrate the chosen-plaintext and known-plaintext attacks. Simulation results and theoretical analysis verify that the presented scheme has high safety performance, a good encryption effect, and a large key space. The method can effectively resist exhaustive, statistical, and differential attacks. Moreover, the encryption time of the proposed method is satisfactory, and the method can be efficiently used in practice for the secure transmission of image information. (shrink)

Museum professionalism remains an unexplored area in museum studies, particularly with regard to what is arguably the core generic question of a sui generis professional knowledge base, and its necessary and sufficient conditions. The need to examine this question becomes all the more important with the increasing expansion of the museum’s roles and functions. This paper starts by mapping out the policy and organizational context within which the roles of museums have expanded in the UK. It then situates the (...) discussion of museum professional knowledge within a cross-disciplinary matrix bearing on the question of what is professional about occupations classified—or classifiable—as professions. Against the backdrop of the current organizational context of the museum as well as theories of professional knowledge, it highlights the ways in which museum work, more specifically museography, poses a distinctive set of questions compared to other ‘professional’ fields; the paper thus homes in on the question of what it is that constitutes the uniqueness of museum professional knowledge in relation to museographic practice and the type of professional knowledge and expertise that can sustain it and enact its creative and educational potentials and affordances.

Given that an analysis of disposition ascription cannot be made in terms of a simple subjunctive conditional, we present a multiply qualified conditional analysis that places disposition ascription within an implicit fundamental causal conceptual typography within which a disposition ascription is embedded, framed, and understood. By placing the multiply qualified analysis within an implicit causal matrix involving a focal cause, pathway of influence, mechanism of action, contributing/partial cause, mediator, extrinsic moderator,, intrinsic moderator, and manifestation, we show how this analysis (...) evades counterexamples and arguments raised against the simple conditional analysis. We then indicate how the causal conceptual landscape provides a roadmap for unpacking and explicating parameters of the ceteris paribus qualifier to acquit the analysis of charges of being vacuous or irredeemably vague.

The intellectual history of Humanity is part of a vast genealogy that stems from disputes between those advocating the excellence of ancient times and those arguing the superiority of the present. Thus, since antiquity we find the persistent recurrence of a Quarrel of the Ancients and the Moderns, virulence that stresses the human and social experience, either praised, either rebuked in its development process. This paper discusses the process of development of the Quarrel of the Ancients and the Moderns as (...) a matrix from which it is possible to perceive, in sparse and seemingly random historical positions, a way that guide us to the path, full of crossings and intersections, of modern experience. Its aim is to define some cardinal points of the Quarrel’s own development that help us to better understand how the idea of “modernity” has evolved. (shrink)

The explosion of multiomics data poses new challenges to existing data mining methods. Joint analysis of multiomics data can make the best of the complementary information that is provided by different types of data. Therefore, they can more accurately explore the biological mechanism of diseases. In this article, two forms of joint nonnegative matrix factorization based on the sparse and graph Laplacian regularization method are proposed. In the method, the graph regularization constraint can preserve the local geometric structure of (...) data. L 2,1 -norm regularization can enhance the sparsity among the rows and remove redundant features in the data. First, SG-jNMF1 projects multiomics data into a common subspace and applies the multiomics fusion characteristic matrix to mine the important information closely related to diseases. Second, multiomics data of the same disease are mapped into the common sample space by SG-jNMF2, and the cluster structures are detected clearly. Experimental results show that SG-jNMF can achieve significant improvement in sample clustering compared with existing joint analysis frameworks. SG-jNMF also effectively integrates multiomics data to identify co-differentially expressed genes. SG-jNMF provides an efficient integrative analysis method for mining the biological information hidden in heterogeneous multiomics data. (shrink)

Environment learning is essential in everyday life. In individuals with Down syndrome (DS), this skill has begun to be examined using virtual exploration. Previous studies showed that individuals with DS can learn and remember paths in terms of sequences of turns and straight stretches, albeit with some difficulty, and this learning is supported by their cognitive abilities. This study further investigates environment learning in the DS population, newly examining their ability to learn a path from actual movements, and to learn (...) increasingly long paths, and how their performance relates to their visuo-spatial abilities and everyday spatial activities. A group of 30 individuals with DS and 30 typically-developing (TD) children matched for receptive vocabulary performed a 4 × 4 Floor Matrix task in a grid comprising 16 squares (total area 2.3 × 2.3 meters). The task involved repeating increasingly long sequences of steps by actually moving in the grid. The sequences were presented in two learning conditions, called Observation (when participants watched the experimenter’s moves), or Map (when they were shown a map reproducing the path). Several visuo-spatial measures were also administered. The results showed a clear difference between the two groups’ performance in the individual visuo-spatial measures. In the Floor Matrix task, after controlling for visuo-spatial reasoning ability, both groups benefited to the same degree from the Observation condition vis-à-vis the Map condition, and no group differences emerged. In the group with DS, visuo-spatial abilities were more predictive of performance in the Floor Matrix task in the Observation condition than in the Map condition. The same was true of the TD group, but this difference was much less clear-cut. The visuo-spatial working memory and visualization tasks were the strongest predictors of Floor Matrix task performance. Finally, the group with DS showed a significant relation between Floor Matrix task performance in the Observation condition and everyday spatial activity. These results enlarge on what we know about path learning in individuals with DS and its relation to their visuo-spatial abilities. These findings are discussed within the frame of spatial cognition and the atypical development domain. (shrink)

Combining the communicative language competence model and the perspective of multimodal research, this research proposes a research framework for oral communicative competence under the multimodal perspective. This not only truly reflects the language communicative competence but also fully embodies the various contents required for assessment in the basic attributes of spoken language. Aiming at the feature sparseness of the user evaluation matrix, this paper proposes a feature weight assignment algorithm based on the English spoken category keyword dictionary and user (...) search records. The algorithm is mainly based on the self-built English oral category classification dictionary and converts the user’s query vector into a user-English-speaking type vector. Through the calculation rules proposed in this paper, the target user’s preference score for a specific type of spoken English is obtained, and this score is assigned to the unrated item of the original user’s feature matrix as the initial starting score. At the same time, in order to solve the problem of insufficient user similarity calculation accuracy, a user similarity calculation algorithm based on “Synonyms Cilin Extended Edition” and search records is proposed. The algorithm introduces “Synonyms Cilin” to calculate the correlation between the semantic items, vocabulary, and query vector in the user query record to obtain the similarity between users and finally gives a user similarity calculation that integrates user ratings and query vectors method. For the task of Chinese grammar error correction, this article uses two methods of predicting the relationship between words in the corpus, Word2Vec and GloVe, to train the word vectors of different dimensions and use the word vectors to represent the text features of the experimental samples, avoiding sentences brought by word segmentation. On the basis of word vectors, the advantages and disadvantages of CNN, LSTM, and SVM models in this shared task are analyzed through experimental data. The comparative experiment shows that the method in this paper has achieved relatively good results. (shrink)

The current WSN is vulnerable to a variety of malicious attacks, resulting in the decline of its comprehensive performance. Multihop routing involves a number of safety and privacy issues. Problems such as snooping, sinkhole, manipulation, cloning, wormhole, spoofing, and so on affect the integrity, availability, and confidentiality of the WSNs. Therefore, this paper mainly studies the mathematical modeling of WSN multiattack behavior discrimination based on the incidence matrix. The WSN node model is used to collect relevant data and mark (...) and map the disguised data, so as to determine the characteristics of multiattack behavior and establish the WSN multiattack behavior discrimination model based on the incidence matrix. The experimental results show that the designed multiattack behavior discrimination model can distinguish the attack type according to the characteristics, has high recognition ability, can spend a short time to effectively distinguish the attack behavior, has a low false positive rate, and can effectively improve the antiattack ability of the WSN.

The specificity of eukaryotic DNA organization into loops fixed to the nuclear matrix/chromosomal scaffold has been studied for more than fifteen years. The results and conclusions of different authors remain, however, controversial. Recently, we have elaborated a new approach to the study of chromosomal DNA loops. Instead of characterizing loop basements (nuclear matrix DNA), we have concentrated our efforts on the characterization of individual loops after their excision by DNA topoisomerase II‐mediated DNA cleavage at matrix attachment sites. (...) In this review the results of applying this mapping approach are compared with the results and conclusions from studies of nuclear matrix DNA. An attempt is also made to reconsider all data about the specificity of DNA interactions with the nuclear matrix and to suggest a model of spatial organization of the eukaryotic genome which resolves apparent contradictions between these data.

Cognition is both empowered and limited by representations. The matrix lens model explicates tasks that are based on frequency counts, conditional probabilities, and binary contingencies in a general fashion. Based on a structural analysis of such tasks, the model links several problems and semantic domains and provides a new perspective on representational accounts of cognition that recognizes representational isomorphs as opportunities, rather than as problems. The shared structural construct of a 2 × 2 matrix supports a set of (...) generic tasks and semantic mappings that provide a unifying framework for understanding problems and defining scientific measures. Our model's key explanatory mechanism is the adoption of particular perspectives on a 2 × 2 matrix that categorizes the frequency counts of cases by some condition, treatment, risk, or outcome factor. By the selective steps of filtering, framing, and focusing on specific aspects, the measures used in various semantic domains negotiate distinct trade-offs between abstraction and specialization. As a consequence, the transparent communication of such measures must explicate the perspectives encapsulated in their derivation. To demonstrate the explanatory scope of our model, we use it to clarify theoretical debates on biases and facilitation effects in Bayesian reasoning and to integrate the scientific measures from various semantic domains within a unifying framework. A better understanding of problem structures, representational transparency, and the role of perspectives in the scientific process yields both theoretical insights and practical applications.

We argue that a map is meaningless unless we have a process for using it. Thus, in this paper, we not only offer the world graph as a representation of relationships among situations the animal has encountered and may encounter again, but we also offer algorithms for how the information encoded in the world graph may be used by the animal in determining its behavior. Each node of the graph encodes a recognizable situation in the animal's world, but a given (...) place may well be encoded in a number of different nodes. Nodes not only require algorithms for the recognition of the situation; they store information about drive reduction associated with the encoded situation. We note that the use of graphs as a basis for exploring some search space is well known in artificial intelligence (AI), but we stress the importance of the animal's exploration of its environment for growing the graph, as distinct from the mathematically described potential nodes frequent in AI search spaces. To explore a number of hypotheses about the way information in the world graph is used to guide the animal's movement, we recall a number of classical experiments on maze exploration by animals, and use them to argue for the nonlocal hypothesis (selection of a path does not depend only upon information about the immediate environment of the animal) and the competing nodes hypothesis (more than one drive may enter into the determination of the animal's behavior at any time). An important feature of the model is that it yields exploration and latent learning without the introduction of an exploratory drive. We also note that the performance exhibited by the model appears to be state-dependent when the animal operates under high drive levels. The drive-interaction matrix is offered as a subject for future research.We complement the presentation of the world graph model, its drive dynamics, and how these are constrained by experiments on maze behavior, with a brief analysis of maps in the brain. We distinguish egocentric maps–which we relate to the many visual systems–from allocentric maps. We offer a somewhat unconventional view of short-term and long-term memory. We examine cooperative computation in somatotopically organized networks, relating this to visually guided behavior in the frog, and to the interaction of colliculus and cortex in the control of eye movements. We examine, but do not advocate, the hypothesis that the hippocampus is a cognitive map. We do stress that if it is a cognitive map, it must be seen as a chart of the local neighborhood, rather than the whole atlas; and we note that the cognitive map hypothesis would lead one to expect the region to exhibit activation of place cells before the animal leaves the previous place.

But Nope is also about visualizing silenced histories.

Furniture industry of Pakistan is considered as one of the high potential yet neglected clusters. This industry is famous for its elaborate wooden carvings on the blocks of Sheeshum and Rosemary. The leading furniture making areas of Pakistan are Chiniot, Gujrat, Peshawar, Lahore and Karachi. However, Pakistan’s share in the international wooden furniture market is insignificant, despite the fact that the country has a history of craftsmanship and innovation in the field of wooden furniture. Especially Sindh region which specializes in (...) wood furniture making have not been explored for its potential in increasing the furniture export. Further, there is a dearth of literature pertaining to their geographical clustering as well as the causes of the underdevelopment of interior Sindh’s wooden furniture industry. In response to this gap, this case study research a) conducts geographical mapping of Khairpur Mirs wooden furniture industry through GIS, and b) constructs a SWOT Matrix in light of Porter’s Cluster Theory on the basis of thematic analysis.

Finally, this research presents policy recommendations to improve this small scale industry’s potential for socio economic growth. (shrink)

In order to define some interesting consequence relations, certain generalizations have been proposed in a many-valued semantic setting that have been useful for defining what have been called pure, mixed and ordertheoretic consequence relations. But these generalizations are insufficient to capture some other interesting relations, like other intersective mixed relations (a relation that cannot be defined as a mixed relation, but only as the intersection of two mixed relations) or relations with a conjunctive (or, better, “universal”) interpretation for multiple conclusions. (...) We propose a broader framework to define these cases, and many others, and to set a common background that allows for a direct compared analysis. At the end of the work, we illustrate some of these comparisons. (shrink)

This dissertation contextualizes the emergence of the Church of Light by Tadao Ando within the Japanese religio-philosophical tradition of nothingness. The idea of nothingness was revived during the first half of the twentieth-century by Kitaro Nishida with two cultural ramifications in the post-war period: a series of dialogues on the points of convergence and divergence between nothingness and the God of Christianity, and an architectural art movement called Monoha, or l'Ecole de Choses. Under the concept of "structuring emptiness," Monoha attempted (...) to restore perceptual depth where dichotomous semiotic representation is overcome through shintaisei, the co-originating corporeal fabric between the subject and object. This two-fold mapping, theological and architectural, not only illuminates the post-war cultural milieu from which Ando's church of spatial emptiness emerged, but also locates the church within the legacy of Nishida's nothingness. ;Nishida's philosophy of nothingness offers a perceptual theory of the "dialectic of self-negation" enacted by shintai, "the actively knowing body." Shintai is the agent of emptying selfhood by functioning as 'the sensational capacity to be filled by' the world. Shintai concretizes the perceptual matrix of co-emergence between the interiority of selfhood and the outside world. When its sensational capacity overflows, shintai enters into the realm of creative action to accommodate the surplus. The figure thus created is not a sign embodying subjective intentions, but constitutes the corporelly-inscribed, pre-reflective experiential datum of the world. Nishida called such a figure "the pure body of the artist," implying its apprehension not as the other in unknowable confrontation, but as the extended self. ;The dissertation examines how this notion of self-renunciatory perception through shintai opens a new hermeneutic horizon for the Church of Light. The church presents an unprecedented conjunction between emptiness, based on the reductive removal of signs, and the cross of light. This seemingly contradictory integration confronts the modern degradation of the cross into an atrophied sign of Christianity and seeks to retrieve its fully efficacious symbolic power. The emptiness contributes to the revival of a deeper communicative mode as shintai by negating the habituated perception pivoted upon the dichotomy between the deciphering subject and the semiotic elements. The perception of light, a natural thing rather than a sign, which infiltrates the cross, is a preliminary ritual to save the perception from the paradigm of the semiotic representation. Shintai, the self-emptying corporeality, resonates with and becomes penetrated by, rather than subjectivizes, the light. On this restored perceptual depth, the cross is perceived not as a sign, but as a part of the pre-reflective, ontological datum constructed and apprehended by shintai. This perceptual experience endorses the associational similarity between the pre-Christian datum predicated upon shintai as the agent of the self-renunciatory subjectivity and Christianity with its theology of the self-transcending love of kenosis.

Context: Humberto Maturana has generated a coherent and extensive explicatory matrix that encompasses his research in neurophysiology, cognition, language, emotion, and love. Purpose: Can we formulate a map of Maturana’s work in a manner that is consistent with the systemic matrix it represents and that serves as an aid for understanding Maturana’s philosophy without reifying its representation? Method: Our arguments are based on experience gained from teaching and presentations. Results: We present a map that that represents Maturana’s main (...) contributions as clusters of notions clustered according to how we see them to be related to each other as a projection of a matrix of ideas onto a two-dimensional space. We claim that there are many paths through these clusters of ideas. Though ideas relevant to individuals are obtained from various partial perspectives, a deep understanding of any element is dependent on an understanding of the whole matrix. Furthermore, we summarize the contributions to this special issue on Maturana. (shrink)

continent. 1.4 (2011): 253—278. A Sense of French Politics Politics itself is not the exercise of power or struggle for power. Politics is first of all the configuration of a space as political, the framing of a specific sphere of experience, the setting of objects posed as "common" and of subjects to whom the capacity is recognized to designate these objects and discuss about them.(1) On April 14, 2011, France implemented its controversial ban of the niqab and burqa , commonly (...) referred to as the Islamic veil, in public places. On the coattails of the 2004 prohibition of religious artifacts, including the less concealing hijab or Islamic headscarves, in schools, the veil ban sparked equal outrage across both political and theological spectra, and many on both sides of the debate were quick to inquire about enforcement. As Steven Erlanger reports, “The police do not have the authority under the law to remove full veils, only to fine or require citizenship lessons for those who violate the new law.”(2) While the legal and social implications of this interdiction are ripe for study, the reprisals for breaking the law, notably compulsory citizenship classes, illuminate the strategic governmentality underlying the French government's targeting of the Muslim community, particularly those elements it considers affiliated with fundamentalist factions and/or terrorist organizations, if only through fashion—an integral component of French citizenship. Indeed, in allowing the (fashion) police to mandate instructional courses in citizenship for offenders, France implies that any Muslim choosing to wear the niqab or burqa , perhaps even for those who are already citizens, must not be aware of the subtle nuances of dress indicative of the French citizenry within public space. Furthermore, the degree of instruction requisite to citizenship, which clearly can and must be updated as the state sees fit, cements the imagined relation between citizens and states within the discourses on the veil ban. As Sharma contends, “Concepts of citizenship are the ideological glue that bonds the nation to the state. Citizenship provides the legal framework through which the state performs its role as ruler for the nation.”(3) Speaking for/as the state, French President Nicolas Sarkozy declared in a 2009 presentation before members of the government and other citizens that the burqa “is not welcome on the territory of France.”(4) Although there is nothing unique, especially recently, about a nation-state taking extreme measures to guard itself against what it deems to be threats to its sovereignty, the way in which the ongoing discourses on hijab have (d)evolved, which coincide with recent pronouncements by governmental leaders in Germany, Britain, and France that policies of multiculturalism have “failed,”(5) points toward nationalist reterritorializations, which is also to say physical and ideological re-appropriations, of public space within democratic milieux, which remain predicated upon the mediation of spaces. As Panagia deduces from Rancière, “Democracy […] is not an institutional form of government […], but an appearance whose visibilities and audibilites arise out of the dissonant blur of the everyday.”(6) Ultimately, the veil ban represents a calculated move to regulate the every day, which is to say the micropolitics of, that which is visible and invisible within French society, which makes it nothing short of a struggle to manage (the sensation of) bodies. Re-situating the political within the context of sense, Rancière argues that the fundamental essence of politics lies within the distinction between consensus and dissensus , and whereas most consider politics proper as fundamentally concerned with the fluid operations of the state— consensus , Rancière actually locates the political within events that disrupt the normative sensory order of things— dissensus . He explains, “Politics revolves around what is seen and what can be said about it, around who has the ability to see and the talent to speak, around the properties of spaces and the possibilities of time.”(7) This reformulation of politics centers on agency and, albeit perhaps unintended, representationality and offers a useful formulation for spatializing the discourses surrounding the Islamic veil, which are mired within seemingly senseless policies and practices of objectification. Instituting a normative “regime of visibility,” the French veil ban encapsulates the political economy of agency, now both mediated and representational, under the rule of nationalist governmentalities in increasingly transnational contexts.(8) Adjudicating presence within public space signals a concern with the sensory aspects of agency itself—what Rancière terms the “distribution of the sensible,” which is “a matrix that defines a set of relations between sense and sense: that is, between a form of sensory experience and an interpretation which makes sense of it.”(9) To be concerned with sense is to focus upon the body, and this somatic repositioning of the (fashionable) citizen within the territory of the state augurs the resurgence of nationalist bio-politics within Europe, since, as Hage explicates, “Nationalism, before being an explicit practice or a mode of classification, is a state of the body. It is a way of imagining one's position within the nation and what one can aspire to as a national.”(10) The French government's attempt to make (bodily) sense of public space for its citizens by and through policies aimed against a burqa-clad Muslim minority, which might only apply to “less then 400 to fewer than 2,000” women(11), reveals the necessary, yet mercurial, transmutation of public space into national space through bio-political strategies of sense-making, which, as Hage observes, denotes that “nationalists perceive themselves as spatial managers.”(12) At the center of this concern over public space is the equally contentious dimension of governing female Islamic identity, which has become one of the main critiques levied against Islam from outsiders who view the veil in its various forms as a clear sign of the religion's actual and symbolic violence against women, even if such critiques remain ensconced within nationalist discourses. As Halim and Meyers argue, “Although Western news media may focus their coverage of Muslim women on the debate over whether and the extent to which the veil may by oppressive to the women who wear it, they have exhibited little interest in the physical oppression of violence against women in Islamic countries.”(13) While it falls outside of the scope of this analysis to arbitrate all of the dimensions of this debate, understanding some of the issues related to female identity and hijab within public space are crucial to this study. As these topics are extraordinarily complex, even and perhaps especially within the Muslim community, it is necessary to provide some context concerning the value, purpose, and meaning of the Islamic veil, which has a rich and arduous history. The Art of the Veil At present, there are only two countries, Iran and Saudi Arabia, that require women to wear hijab , which is a decidedly problematic term and concept whose locus is itself caught within a struggle of sensation. Noting the strategic reterritorialization of the term, Berger explains: The choice of the name, hijab , now widely adopted to designate the “Islamic veil,” it itself interesting, although the semantic shift it operates is not directly commented upon by its users. Although the design (both the cut and the symbolic function) of the hijab and the Iranian chador are indeed the same, as opposed, for instance, to the traditional Algerian haik , the word hijab has come to replace the term chador popularized by the Iranian revolution, as a properly Arabic (hence Koranic) designation. This discursive shift points to the successful reclaiming of the national revolution in Iran by a transnational pan-Islamic movement, whose language of reference can only be Koranic Arabic.(14) While the hijab is certainly a point of contention within various countries dealing with immigrant Islamic populations (of which France has the largest in Europe as part of its colonial legacy in Algeria), it is clear that the veil is a historically contextualized artifact of Muslim identity with a variety of manifestations, even as forces outside of and within Islam seek to codify its actual and symbolic value. Ultimately, the varieties of hijab , including the full-faced burqa and niqab , are complex assemblages of meaning that speak to the multitudinous flows of Islamic identities over time and space. As Gökariksel and McLarney observe, “Wearing a certain style of veil may simultaneously be a disciplinary practice crucial to the cultivation of piety (Mahmood 2005; Gokariksel 2009) and a gendered performance of social distinction in terms of class, taste, and urbanity (White 1999; Navaro-Yashin 2002; Gokariksel and Secor 2009) or of ethnicity and race (Dwyer 1999).”(15) The ideological marketplace from which the varieties of hijab ebb and flow serves both as a reflection of the ever-present materiality and dynamic functionality of spiritual economies, which are derivative of the equally ubiquitous flows of transnational capital driving agency and representationality within our historical moment. Keeping these dual, yet deeply interconnected, capital ecologies as the site of exploration for how the veil is represented within public space, one might begin to sense what lurks behind such veiled agendas. Examining the symbolic and representational nature of the Islamic “veil” in its various forms, this project situates the decidedly political contestations of public space at stake in the French ban alongside recent condemnations of multiculturalism as calculated efforts to re-distribute the sensible so as to valorize national identity within increasingly transnational and globalized socio-economic spaces, which collapse exchange values between distinct, yet interwoven, economies of (cultural/material/spiritual) capital. As the discourses on the veil rely upon representational imag(in)ings, it seems fitting to explore the political economy and art of the veil through the phenomenon of street art, which, much like hijab , is a complex assemblage of meaning of sensation mired in representationality and capital exchange. As street artists have taken up hijab in various forms, the movement offers a lens with which to situate critical responses to the veil debate across both spiritual and material economies. Situating this street art both aesthetically and historically, Lewisohn explains, “'Street art' is a sub-genre of graffiti writing and owes much to its predecessor. Though there is a good deal of crossover between the genres, they are distinct and separate in their own right.”(16) Evolving out of the graffiti explosion of the late 1970's and 1980's, street art broke the unspoken rules of the artistic underground by challenging and re-examining one's sensory experience of art in public space by experimenting with both content and form in ways that harken back to the Situationist International, which as a collective challenged one's experience of urban space through various media and experiential phenomena. Again, Lewisohn observes, “It's important to note street art's break with the tradition of the tag, and its focus on visual symbols that embrace a much wider range of media than graffiti writers would use.”(17) From stencils to prints and murals to one-liners, street artists developed a reputation for critical social and political commentary, and while it is certainly the case that not all street art is intentionally political, in challenging the normative “regime of visibility,” as Rancière puts it, of public space, street artists—even if unconsciously—call into question the common sensory experience of the politics underlying the formation of (nationalist) space.(18) Indeed, Rancière refers to the partisan sensory managers as “police,” who ultimately forge “the rules governing the circulation of appearances, of their visibility and audibility, and the proper distribution of bodies therein.”(19) As such, one can sense that street art's relationship with the police is tenous for a variety of reasons. Writing about his own experience as a street artist, Shepard Fairey observes, “With street art, there's no committee deciding whether I can put my work up on the street, there's no censorship, and I have total freedom of expression, and that concept of freedom is expressed just by using the street as a medium.”(20) As Fairey and other street artists demonstrate, the medium, to paraphrase Marshall McLuhan, is the most glaring aspect of street art's message, and even as it now finds itself in galleries and usurped by private collectors, the ethos of the movement remains relavent to politics as it is, first and foremost, concerned with the configuration and experience of space. Just as examining the punishments for breaking the veil ban can map the terrain of French politics, a representational genealogy of street artist's deployment of hijab and female Muslim identity can assist in mining the depths of public space as a site of bio-political control and contestation in light of recent events in France and the rising tide of anti-multiculturalist rhetoric across Europe, even though the Islamic presence there is radically heterogenous. Using the work of Shepard Fairey, Princess Hijab, br1, and Banksy, this paper sets out to answer a number of key questions concerning the deployment of hijab, and female Islamic identity in particular, within street art as a movement now integral to and critical of the economies of exchange underlying global capitalism, which as a force of influence cannot be underestimated as a driver in the resurgence of nationalist biopolitical governmentalities. Although there exists a litany of artists to choose from, the aforementioned quartet of designers integrate hijab into their work in a seminal and critical fashion, and all have been working with the veil in some way prior to the French ban, which grants some additional context to their usage of it as a symbol in regards to the breakdown of multiculturalism across Europe, even if unconsciously. Although each artist depicts various amalgamations of hijab in their respective corpus, they share common tropes that raise significant questions concerning the veil debate, namely: what are the conditions of possibility for hijab to become a marker of Islamic identity within public space? How can we make sense of the representational topologies within street art's utilization of the hijab and female Islamic identity in light of the French ban? How might these aesthetic imag(in)ings simultaneously inhabit and combat normative discourses concerning hijab , multiculturalism, female Islamic identity, and public space? With these considerations as a backdrop, it is first necessary to outline more fully the hijab as a representative marker of female Islamic identity. The (Veiled) Writing on the Wall

This paper presents an in-depth analysis and research on the spatial distribution pattern of the urban landscape in the Central Plains digital landscape form and proposes an optimization scheme. Based on the basic theories of systematics and complexity, this paper analyzes the self-similar characteristics of urban morphology, establishes the concept of schema, and constructs a multiscale and multilevel morphological map research framework by drawing on the “planar pattern” morphological analysis method of the school and the “matrix, patch, and corridor” (...) spatial expression model of landscape ecology. The framework of morphological map research at multiple scales has been established, and the theory and method of describing, understanding, judging, and analyzing morphological evolution have been formed. Cities have self-similarity at different scales, and urban evolution is a process of recursion from small-scale hierarchy to large-scale hierarchy, and hierarchy is a phenomenon presented by the natural evolution of cities. After any morphological process is completed, it can only be transformed into the other two ways, so the static morphological description can be transformed into dynamic morphological process analysis.

Reappraisal is a frequently used and often successful emotion regulation strategy. However, its underlying cognitive mechanisms are not well understood. In this paper, we seek to clarify these mechanisms by expanding upon our recently proposed reAppraisal framework. According to this framework, reappraisal consists of appraisal shifts that arise from changes to the mental construal of a situation (reconstrual) or from changes to the goals that are used to evaluate the construal (repurposing). Here we propose that reappraisal can target both object-level (...) construals and goals representing states in the environment as well as meta-level construals and goals about different states in the mind. We also propose that reappraisal can operate by facilitating decommitment from a dominant construal or goal as well as by facilitating commitment to alternative construals or goals. We demonstrate that the 2 × 2 × 2 matrix formed by crossing the three distinctions between reconstrual and repurposing, between object-level and meta-level representations, and between decommitment and commitment operations forms a useful map of different reappraisal tactics. We draw examples of each of the 8 reappraisal tactics from basic and clinical research. We conclude by considering future research inspired by the expanded reAppraisal framework. (shrink)

This paper explores the commitment to corporate citizenship on the part of the largest U.S.-based multinationals in the emerging market region of Latin America. The websites of the largest U.S.-based firms - according to the 2007 Fortune 500 list - are reviewed and their CSR efforts in Latin America are noted. The firms' positions on corporate citizenship in Latin America are mapped onto a three-by-three matrix in which firms' commitment to corporate citizenship ranges from profitmaking motivations to a more (...) holistic approach where support for non-profit causes is embraced by the entire firm and implemented at all levels, 9-26, 2000). The largest U.S.-based multinationals were selected for this study because of their leadership role and the fact that other firms within their respective industries may seek to emulate the firms' level of commitment to corporate citizenship. While the matrix can be used to evaluate corporate citizenship efforts in any market - or globally - the emphasis in this study is on Latin America, a region of interest for two reasons: because of the paucity of research on this particular emerging market region as it relates to CSR, and because there is some evidence to suggest that philanthropic initiatives by the region's wealthy individuals lag behind individual philanthropic efforts in other world regions. If this is the case, this study aims to identify whether companies are picking up the slack. (shrink)

Excitation at widely dispersed loci in the cerebral cortex may represent a neural correlate of consciousness. Accordingly, each unique combination of excited neurons would determine the content of a conscious moment. This conceptualization would be strengthened if we could identify what orchestrates the various combinations of excited neurons. In the present paper, cholinergic afferents to the cerebral cortex are hypothesized to enhance activity at specific cortical circuits and determine the content of a conscious moment by activating certain combinations of postsynaptic (...) sites in select cortical modules. It is proposed that these selections are enabled by learning-related restructuring that simultaneously adjusts the cytoskeletal matrix at specific constellations of postsynaptic sites giving all a similar geometry. The underlying mechanism of conscious awareness hypothetically involves cholinergic mediation of linkages between microtubules and microtubule-associated protein-2 . The first reason for proposing this mechanism is that previous studies indicate cognitive-related changes in MAP-2 occur in cholinoceptive cells within discrete cortical modules. These cortical modules are found throughout the cerebral cortex, measure 1–2 mm2, and contain approximately 103–104cholinoceptive cells that are enriched with MAP-2. The subsectors of the hippocampus may function similarly to cortical modules. The second reason for proposing the current mechanism is that the MAP-2 rich cells throughout the cerebral cortex correspond almost exactly with the cortical cells containing muscarinic receptors. Many of these cholinoceptive, MAP-2 rich cells are large pyramidal cell types, but some are also small pyramidal cells and nonpyramidal types. The third reason for proposing the current mechanism is that cholinergic afferents are module-specific; cholinergic axons terminate wholly within individual cortical modules. The cholinergic afferents may be unique in this regard. Finally, the tapering apical dendrites of pyramidal cells are proposed as primary sites for cholinergic mediation of linkages between MAP-2 and microtubules because especially high amounts of MAP-2 are found here. Also, the possibility is raised that muscarinic actions on MAP-2 could modulate microtubular coherence and self-collapse, phenomena that have been suggested to underlie consciousness. (shrink)

I should say a preliminary word about the method I am adopting in this article, mainly to point out that there is nothing whatever remarkable about it. I take myself to be approaching the Politics in accordance with the interpretative canons standard in mainstream historical and Aristotelian scholarship. Compare the study of Aristotle's metaphysics. Everyone would grant that before we start considering whether hule or indeed any other Aristotelian concept anticipates or maps onto some modern notion of matter in any (...) interesting or important way, it is imperative to acquire a full understanding of the way the idea functions within the whole matrix of concepts, analyses, and theses which make up Aristotle's physics and metaphysics. I am simply pursuing the same method with respect to that matrix of concepts in Aristotle's political philosophy within which Miller hopes to locate an anticipation of the idea of rights. My references to the work of John Pocock in section V have suggested to some readers that I am espousing a form of historical or cultural or Kuhnian relativism which rules Miller's project out of court ab initio. The only form of relativism to which I think this essay commits me is the methodological relativism that I have just described. (shrink)

This article reviews Hestenes' work on the Dirac theory, where his main achievement is a real formulation of the theory within thereal Clifford algebra Cl 1,3 ≃ M2 (H). Hestenes invented first in 1966 hisideal spinors $\phi \in Cl_{1,3 _2}^1 (1 - \gamma _{03} )$ and later 1967/75 he recognized the importance of hisoperator spinors ψ ∈ Cl 1,3 + ≃ M2 (C).This article starts from the conventional Dirac equation as presented with matrices by Bjorken-Drell. Explicit mappings are given for (...) a passage between Hestenes' operator spinors and Dirac's column spinors. Hestenes' operator spinors are seen to be multiples of even parts of real parts of Dirac spinors (real part in the decompositionC ⊗ Cl 1,3 andnot inC ⊗ M4 (R)=M4 (C)). It will become apparent that the standard matrix formulation contains superfluous parts, which ought to be cut out by Occam's razor.Fierz identities of bilinear covariants are known to be sufficient to study the non-null case but are seen to be insufficient for the null case ψ†γ0ψ=0, ψ†γ0γ0123ψ=0. The null case is thoroughly scrutinized for the first time with a new concept calledboomerang. This permits a new intrinsically geometric classification of spinors. This in turn reveals a new class of spinors which has not been discussed before. This class supplements the spinors of Dirac, Weyl, and Majorana; it describes neither the electron nor the neutron; it is awaiting a physical interpretation and a possible observation.Projection operators P±, Σ± are resettled among their new relatives in End(Cl 1,3 ). Finally, a new mapping, calledtilt, is introduced to enable a transition from Cl 1,3 to the (graded) opposite algebra Cl 3,1 without resorting to complex numbers, that is, not using a replacement γμ →iγμ.

In this paper, dynamic behavior analysis has been discussed for a class of switched complex-valued neural networks with interval parameter uncertainties and impulse disturbance. Sufficient conditions for guaranteeing the existence, uniqueness, and global robust exponential stability of the equilibrium point have been obtained by using the homomorphism mapping theorem, the scalar Lyapunov function method, the average dwell time method, and M-matrix theory. Since there is no result concerning the stability problem of switched neural networks defined in complex number (...) domain, the stability results we describe in this paper generalize the existing ones. The effectiveness of the proposed results is illustrated by a numerical example. (shrink)

The term ‘Third World’ was first used in 1952 by the French economist ­Alfred Sauvy­ in order to stress the division between the liberal ‘First’ world, the communist ‘Second’, and the rest of the non­aligned ‘Third’ world. During the 1970s and 1980s, the confrontation between the East and the West polarized the dissemination of the architecture and planning concepts. The export of ‘Modernism’ and its adaptations to the conditions of ‘Third World’ from Socialist and Capitalist countries introduced the new paradigms (...) of reconstruction and resettlement policies that create new urban identities in these countries. Rendering the importance of the complex relationship between interrelated politics in the geopolitical matrix of world war responses to a series of problematic questions on actual architectural concepts and meta­political strategies that frame social life in an oppressive frame. In cold war politics, urban planning was considered to be a powerful instrument, and that the export of architecture and planning functioned as a political apparatus by non­ government aid organizations, philanthropic foundations, corporations, and individual professionals. Through archival materials including historical documents, drawings, photographs, maps, planning transfers, and reconstruction strategies, this paper aims to show how we can re­conceptualize architecture and urban planning as a political apparatus of transnational transfer during the Post­war reconstruction projects to create a new urban identity.

A dimensional reduction algorithm is applied to an intelligent classification model with the purpose of improving the efficiency and accuracy. The proposed classification model, used to distinguish the operating mode: Hard- and Soft-Switching, is presented and an analysis of the synchronized rectified step-down converter is done. With the aim of improving the accuracy and reducing the computational cost of the model, three different methods for dimensional reduction are applied to the input dataset of the model: self-organizing maps, principal component analysis (...) and correlation matrix. The obtained results show how the number of variable is highly reduced and the performance of the classification model is boosted: the results manifest an improve in the accuracy and efficiency of the classification.

This thesis is concerned with extending the underlying logical approach as well as the breadth of applications of the proof mining program to various (mostly previously untreated) areas of nonlinear analysis and optimization, with a particular focus being placed on topics which involve set-valued operators.For this, we extend the current logical methodology of proof mining by new systems and corresponding so-called logical metatheorems that cover these more involved areas of nonlinear analysis. Most of these systems crucially rely on the use (...) of intensional methods, treating sets with potentially high quantifier complexity in the defining matrix via characteristic functions and axioms that describe only their properties and do not completely characterize the elements of the sets.The applicability of all of these metatheorems is then substantiated by a range of case studies for the respective areas which in particular also highlight the naturalness of the use of intensional methods in the design of the corresponding systems.The first new area covered thereby is the theory of nonlinear semigroups induced by corresponding evolution equations for accretive operators. In that context, we present (besides an initial foray into the area from 2015) essentially the first applications of proof mining to the theory of partial differential equations. Concretely, we provide quantitative versions of four central results on the asymptotic behavior of solutions to such equations.The second new area unlocked in this thesis is that of the continuous dual of a Banach space and its norm (which are also approached via intensional methods). This in particular relies on a proof-theoretically tame treatment of suprema over (certain) bounded sets in this intensional context which is further exploited later on. These systems, which give access to this until now untreated fundamental notion from functional analysis, are then used to provide further substantial extensions to treat various notions from convex analysis like the Fréchet derivative of a convex function, Fenchel conjugates, Bregman distances, and monotone operators on Banach spaces in the sense of Browder.These systems are then utilized to provide applications in the context of Picard- and Halpern-style iterations of so-called Bregman strongly nonexpansive mappings where we provide both new quantitative and qualitative results.Lastly, we discuss the key notion of extensionality of a set-valued operator and its relation to set-theoretic maximality principles in more depth (which was already singled out—to some degree—in previous work). We thereby exhibit an issue arising with treating full extensionality in the context of these intensional approaches to set-valued operators and present useful fragments of the full extensionality statement where these issues are avoided.Corresponding to these fragments, we discuss a range of uniform continuity statements for set-valued operators beyond the usual notion involving the Hausdorff-metric. In particular, in that context, we utilize the previous tame treatment of suprema over bounded sets to also provide the first proof-theoretic treatment of that Hausdorff-metric in the context of systems for proof mining.The applicability of this treatment of the Hausdorff-metric is then in particular substantiated by a last case study where we provide quantitative information for a Mann-type iteration of set-valued mappings which are nonexpansive w.r.t. the Hausdorff-metric.The abstract was taken directly from the thesis.Abstract prepared by Nicholas Pischke, Technische Universität Darmstadt, Darmstadt, GermanyE-mail: pischke@mathematik.tu-darmstadt.de.URL: https://doi.org/10.26083/tuprints-00026584.

This paper presents, explains, and addresses the pedagogical utility of the “Wachter crystal,” a three-dimensional representation of basic principles of logic designed and created by Thomas Wachter in 1992. The author first discusses a way of understanding relations of logical inference which groups propositions possessing identical truth tables into the same class (that is, a way of conceptualizing rules for replacement). Next, the author presents and explains a 16 x 16 matrix, the most basic figure for representing the inferential (...) relations between the classes of propositional logic. Such a matrix easily maps reflexivity, asymmetry, and transitivity in relations of implication. Moreover, since the relations and properties it illustrates can also be illustrated by a lattice, one can construct a three-dimensional model to represent them. The Wachter crystal, which resembles chemists’ models of molecules, illustrates the same principles as the matrix while foregrounding the commonly-neglected difference between Philonian conditionals (which belong to the object language of propositional logic) and implication (which belong to the metalanguage). In addition to being a perspicuous and aesthetically engaging way to represent basic principles of propositional logic, the Wachter crystal is a bridge to more advanced logical concepts such as modal logic, sentence connectives, and predicates of sentences.

This axiomatization is based on the observation that ifG is the group of automorphisms of the states (induced, e.g., by suitable evolutions), then we can define a spherical function by mapping each element ofG to the matrix of its transition probabilities.

He wanted to become a systematic hermeneutics, (...) and criticism of previous hermeneutics is "the rules of the merger," and the lack of coherence. Wu Ning speaking, they deal with different issues is a combination of methods. 施莱尔玛赫hermeneutics points to avoid misunderstanding of the text. This part is up to the final discussion of施莱尔玛赫criticism of the United States. 2. Dilthey contribution to the philosophical hermeneutics of Dilthey on施莱尔玛赫In order to write the thesis, including In order to Protestant hermeneutics history, from the Reformation to the future as a second reference books. He was a learned scholar and has been on many topics regardless above. For our purposes, Dilthey is a philosopher with a passion for life, he was placed In order to humanities and social sciences and natural sciences in an established full equality of points, by the foundation on the hermeneutics In order to develop a basic methodology. But in the science competition, he was seeking "Allgemeingultigkeit", a universal validity, to do so In order to give him too much towards the foundation to the scientific methods of thought. He is still a major development of the character of philosophical hermeneutics. 3 Heidegger before and on philosophical hermeneutics, "and there is time" contribution to the development of philosophical hermeneutics is the decisive shift in Heidegger, born with the future, there are original philosopher The early works. He Freiburg Hu plugs Seoul assistant, and in the phenomenological Hu stopper Seoul In order to create a useful set up beyond the traditional methods of philosophy, but he is still too dependent on science Hu stopper Marco effectiveness. Part I: description of the evolution of the early Heidegger: "ontology - the fact of hermeneutics," the book published after the death of Heidegger was published in 1999, English translation, Heidegger in this series by the fact that the ontology of hermeneutics In order to give us a hermeneutic understanding of his meaning. In order to avoid the traditional hermeneutics of his meaning, In order to return to the ancient hope臘hermeneueinc and hermeneia idiom. He attempts to go beyond the limits of contemporary objects, through the period of return to the ancient hope臘general language idioms. Hermeneutic encounter with the interpretation of Homer's description of the mouth, publish, translate and interpret. His description of historical hermeneutics in the pull-down maps and sub ​​Lane Park after a groundbreaking Aristotle hope臘idioms in the loss of richness and decline. But the hermeneutics of Heidegger speaking the method is close to something, such as early speech hermeneutics In order to approach closer to the truth of it is understandable the former interpretation of this domain as there face life. For this last hermeneutics as the method of self-understanding, but in a letter to his students Engelbert Kerbs letter, Heidegger also emphasizes the history In order to recognize the character. Us from our understanding of historical context, our understanding of the structure is formed by shaping the concept of history and even our language. In Dilthey's hermeneutics, he also stressed that understanding the historical basis. From Dilthey to Heidegger this view. Heidegger in his speech defines hermeneutics as "the fact of participation, close, and descriptions of the same interrogation methods." Hermeneutics is the interpretation of not only understanding knowledge as a negative process, but active participation, interrogation and close. Fact of itself is interpreted, it is through understanding the questions and answers something. Heidegger back to the necessary conditions for our understanding of factors, understanding of "the former structure." He describes some part of the former, is awareness and understanding of nature, we understand something "to" something, and we understand it in a specific historical context. Further more, we expect to understand it in the presence of a sight, not a determining sexual arousal by the sight, by the basic problems of the future horizon, it is "the possibility of there," the sight, for there is a special special possible time horizon. These early works of Heidegger has been found there the possibility of meaning. We all都leadership to a new concept of the humanities. In addition, as a rational animal, as Aristotle said sub-Lane, who is of a future there may not be included, including the timing of there. People are looking to understand their own there. Instructions to Heidegger, hermeneutics offers a new concept for the person's point of view. Part II: there and time hermeneutics is first mentioned in the "there and the time," Section VII, Heidegger phenomenology has been interpreted as if it is. In order that he found "the meaning of phenomenological description as a way to rely on hermeneutics, phenomenology of this and some of the logos have hermeneuein the characteristics of this phenomenology is to use some basic meaning of the word hermeneutics, it indicates the work In order to interpret . "In the second sense, Heidegger found in hermeneutics裡are there for the meaning of this method of exposing the shield. The third meaning is the interpretation of this promising continuous manner so that its future is possible, it's future there. Section 31 of hermeneutics is important, because there is some understanding that is. Understanding the process is the center of human existence, in Section 32 entitled "interpretation and understanding," understanding the interpretation built on. Visit the world around it and understand things as this or that, always never as pure consciousness. As Heidegger said, "always had to watch as the ability to understand and interpret", in other words, there is no precedence in the interpretation of pure consciousness, there is always ask questions and interpretation of the visual field. Section 44, regardless Heidegger also true about management, in its modern form as a true statement, is always carried a deeper understanding and interpretation of the export process. But the really right is defined as the management there has been an associate of knot, so it access to basic ontology of sight. It is obvious that there's open, this hole is to guide him toward the police point of view of the artistic part of the next lecture will be discussed. This lecture primarily presents the two early works of Heidegger in which hermeneutics plays a definitive role. As background, the contributions of Schleiermacher and Dilthey are presented briefly before going into Heidegger's contribution. Ⅰ. Schleiermacher's Contribution to the Development of a Philosophical Hermeneutics Schleiermacher made a decisive turn in the history of hermeneutics when he proposed a "Universal Hermeneutics," a hermeneutics that would apply to all kinds of text interpretation. While traditional hermeneutics included moments of understanding, explication and application, Schleiermacher focused on hermeneutics as the "art of understanding . "Schleiermacher also introduced psychological interpretation whereby one tried to penetrate the individuality and soul of the author of a text. He wanted hermeneutics to be systematic, and he criticized previous hermeneutics for being only an" amalgam of rules "and lacking systematic coherence. Rather , they were methods for dealing with an array of different kinds of problems. Schleiermacher's hermeneutics was directed at avoiding misunderstanding of the text. At the end of this section Gadamer's criticisms of Schleiermacher will be discussed. Ⅱ. Dilthey's Contribution to Philosophical Hermeneutics Dilthey wrote his dissertation on Schleiermacher and included a history of Protestant hermeneutics since the Reformation as a second companion volume. He was a broadly educated professor and wrote on many topics. For our purposes, Dilthey was a life-philosopher with a passion for placing the Humanities and Social Sciences on an equal footing with the Natural Sciences by developing a basic methodology for them based on hermeneutics. But in competing with the sciences, he sought an "Allgemeingultigkeit," a universal validity, and in doing so he tended to give too much ground to the way of thinking in the sciences. Still, he is a major figure in the development of philosophical hermeneutics. Ⅲ. The Contribution of Martin Heidegger to Philosophical Hermeneutics before and in Being and Time The decisive turn in the development of a philosophical hermeneutics came in the early writings of Martin Heidegger, a radical and original philosopher. He was in Freiburg an assistant to Husserl and found in Husserl's phenomenology a useful way of overcoming traditional philosophy, but he still found Husserl too preoccupied with scientific validity. Part Ⅰ: Heidegger's Early Lectures: Ontology-the Hermeneutics of Facticity A posthumously published and translated set of Heidegger's lectures on ontology in terms of a hermeneutics of facticity gives us a sense of his understanding of hermeneutics. He bypassed the traditional sense of hermeneutics and went back to the Greek usage of hermeneuein and hermeneia. He attempted to overcome the limitations of modern objectivity by returning to the usages current in ordinary language in ancient Greece. There hermeneutics meant orally interpreting Homer, announcing, translating, and explaining. His account of the history of hermeneutics after Plato and Aristotle is a history of decline and loss of the richness found in Greek usage. But hermeneutics for Heidegger meant a means of access to something, and in these early lectures hermeneutics became an interpretive means of access to facticity, to the realm of pre-interpretive understanding as Dasein faces life. Ultimately hermeneutics became a means for the self-understanding for Dasein. But in a letter to his student, Engelbert Krebs, Heidegger also emphasizes the historical character of cognition. We understand from our situation in history, and our understanding is structured by historically shaped concepts and even our language. Dilthey, too, emphasized the historical matrix for understanding in his hermeneutics, and Heidegger took this up from Dilthey. Heidegger defined hermeneutics in the opening lines of the lectures as "the unified manner of the engaging, approaching, accessing, interrogating, and explication of facticity." Hermeneutics as interpretation is not just understanding as a passive process of cognition but an active engaging, interrogating, and accessing. Facticity itself is interpretive in that it sees what something is through question and answer. Heidegger is stepping back into the factors that precondition our understanding, the "forestructure" of understanding. This forehaving, he says, belongs to the very nature of knowing and understanding. We see something "as "something, and we see it in a specific historical situation. Furthermore, we see it in an existential horizon of expectation, a horizon haunted by uncertainty, by the" fundamental questionability of the future, that is of "possible being," of what is possible for this particular being at this particular time and place. Already in these early works Heidegger finds in the sense of what is possible being, a sense of "ontic questionability, care, restlessness, anxiety, temporality." All of this leads to a new conception of humanity. Instead of being an animal endowed with reason, as in Aristotle, a human being is a being with a possible future, a being with temporality. Humans are beings seeking to know themselves. Hermeneutics, Heidegger says, offers the standpoint for a new conception of the human being. Part Ⅱ: Being and Time The first mention of hermeneutics is in section 7 of Being and Time, where Heidegger is already interpreting phenomenology as letting what is show itself. He finds that " the meaning of phenomenological description as a method lies in interpretation. The logos of the phenomenology of Dasein has the character of hermēneúein. The phenomenology of Dasein is a hermeneutic in the original signification of the word, where it designates the work of interpreting. "In a second sense, Heidegger finds in hermeneutics a means of uncovering the meaning of being for Dasein. And the third sense is the interpretation Dasein as continually making its future possibilities, its future being. Section 31 is important to hermeneutics because there the being of Dasein is said to be understanding. Understanding is the central process of an existing human being. In section 32, titled "Understanding and Interpretation," interpretation builds on understanding. It looks around at the surrounding world and sees things as this or that, always already , never as pure perception. As Heidegger puts it, "The seeing of this sight is always already understanding and interpreting." In other words, there is no pure perception prior to interpretation; there is always the horizon of questioning and interpreting. In section 44, Heidegger argues that truth, too, in its modern forms as statements which are true, is derivative from the deeper processes of understanding and interpreting that are always already going on. But when truth is rightfully defined in connection with being, then it moves into the horizon of fundamental ontology. It is the disclosure of being. This insight is part of what leads him to his view of art, which we will discuss in the next lectur. (shrink)

Data hiding and watermarking are considered one of the most important topics in cyber security. This article proposes an optimized method for embedding a watermark image in a cover medium (color image). First, the color of the image is separated into three components (RGB). Consequently, the discrete wavelet transform is applied to each component to obtain four bands (high–high, high–low, low–high, and low–low), resulting in 12 bands in total. By omitting the low–low band from each component, a new square (...) class='Hi'>matrix is formed from the rest bands to be used for the hiding process after adding keys to it. These keys are generated using a hybrid approach, combining two chaotic functions, namely Gaussian and exponential maps. The embedding matrix is divided into square blocks with a specific length, each of which is converted using Hessenberg transform into two matrices, P and H. For each block, a certain location within the H-matrix is used for embedding a secret value; the updated blocks are assembled, and the reverse process is performed. An optimization method is applied, through the application of the firework algorithm, on the set of the initial values that generate keys. Using an optimization procedure to obtain keys requires performing lowest possible change rate in an image and maintain the quality of the image. To analyze and test the efficiency of the proposed method, mean-square error (MSE) and peak signal-to-noise ratio (PSNR) measurements are calculated. Furthermore, the robustness of the watermark is computed by applying several attacks. The experimental results show that the value of the MSE is reduced by about 0.01 while the value of the PSNR is increased by about 1.25 on average. Moreover, the proposed method achieved a high-retrieval rate in comparison with the non-optimization approach. (shrink)

Purpose Previous studies on cyberloafing have so far not focused on the interlinkages among push factors, pull factors, consequences of actions and value orientations of the employees in a comprehensive manner. The purpose of this study is to close that gap by integrating push-pull theory with means-end chain framework. Design/methodology/approach Using a soft-laddering technique, semi-structured interviews were conducted with 21 Indian employees from various organizations with prior written consent. After performing the content analysis and preparation of ladders, an implication (...) class='Hi'>matrix and a hierarchical value map were constructed using the LadderUX tool. Findings “Upholding conversational conformity,” “achieving efficiency through noise cancellation,” “addressing occasional requirements,” “social networking as a coping mechanism,” “staying informed and sharing opinions,” “attempting job or profile alteration” and “fulfilling transactional obligations” turned out to be the seven prominent means-end chain patterns, with their respective push-pull factors, consequences and value orientations. This study also suggested the multifaceted character of cyberloafing in a continuum, from “serious-destructive” to “minor-positive” to “facilitative-productive.” Research limitations/implications This study has been conducted by focusing on cyberloafing at physical workplaces and not in the context of distributed work environments. Practical implications The findings of this study will enable organizations to frame an appropriate set of guidelines to control this behavior. Originality/value To the best of the authors’ knowledge, this study is the first to integrate the push-pull theory and means-end chain framework to explore the nuances of cyberloafing among employees.

In lieu of an abstract, here is a brief excerpt of the content:Reflections on DuchampBergson ReadymadeFederico Luisetti (bio)Translated by David Sharp[I]nside the person we must distinctly perceive, as through a glass, a set-up mechanism.—Henri Bergson, Laughter: An Essay on the Meaning of the Comic (1901)In spite of the enormous critical attention paid to Marcel Duchamp’s art and theoretical background, the dialogue with Bergsonism is mostly confined to scattered references and erudite observations.1 Paradoxically, the major obstacle to this encounter has been (...) the immense popularity of Henri Bergson’s philosophy since the initial decade of the twentieth century. Such success has come with a price, however, for the proliferation of neutralizing schematizations has progressively suffocated the specificity of his thought and subsequently impeded the understanding of his epistemological radicalism, so cherished by Duchamp and the historical avant-garde.2Consider, for example, how the specter of Bergson constantly hovers over Linda Dalrymple Henderson’s authoritative discussion of Duchamp’s scientific sources. Although Henderson recognizes the diffuse presence in Duchamp of various Bergsonian motives, because she regards Bergson as the antiscientific philosopher of the “inner self” and of “profound self-expression,”3 Bergsonian notions seem to her incompatible with the artistic revolution prompted by Duchamp. A historiographical exorcism is therefore needed in order to heal the consequences of the traumatic Bergson-Duchamp incest. Herein lies Henderson’s solution: since Duchamp rejects the aesthetic principles of the Puteaux Cubists, he also abandons Bergsonism, which represents their philosophical matrix. Thus, the Bergsonian ideas “undoubtedly” present in Duchamp’s artistic lexicon are nothing but debris accumulated in the course of his battle with the Cubist disciples of Bergson.4To counter these approaches, in the following pages I will map Duchamp’s absorption and creative distortion of Bergsonism,5 concentrating on key terms of both Bergson’s philosophy and Duchamp’s speculations on art: space, “readymade,” delay, body, virtual, circuit, machine.6 I will then discuss the theoretical implications of Duchamp’s Bergsonism and place the readymade7 within its proper context: the deconstruction of the Western metaphysics of reflection. [End Page 77]SpaceBeginning with Time and Free Will (1889), Bergson distinguishes between two types of multiplicities: on the one hand, “duration” (durée), “an internal multiplicity of succession, of fusion, of organization, of heterogeneity, of qualitative discrimination... a virtual and continuous multiplicity that cannot be reduced to numbers,” and on the other, “a multiplicity of exteriority, of simultaneity, of juxtaposition, of order, of quantitative differentiation... a numerical multiplicity, discontinuous and actual.”8 This opposition is generally understood as a clear-cut differentiation between the inner experience of time and the objective consistence of space. In Time and Free Will and Matter and Memory (1896), there are several passages that can be read accordingly, since duration is often described as a continuous, indivisible temporal experience, and space as that which “by definition, is outside us.”9Yet for Bergson space and time are mixed terms, and their internal complexity does not coincide with the semantic distinction between the two multiplicities. Deleuze has clearly formulated the central difficulty that a reductionist theory of space and time would imply, a problem of which Bergson is fully aware. Since the concept of duration has an ontological span, space must find a place within time and vice versa: “If things endure, or if there is duration in things, the question of space will need to be reassessed on new foundations. For space will no longer simply be a form of exteriority.... Space itself will need to be based in things... to have its own ‘purity’” [Deleuze, Bergsonism 49]. Hidden behind the motif of the “spatialization of time,” Bergson has devised a stratified theory of space, whose origins we can trace back to his philosophical apprenticeship [see Heidesick 29–42].Departing from Kant, Bergson introduces a boundary between the “perception of extension” and the “conception of space,” between qualitative space, which he calls “extensity” (étendue), and “abstract,” “homogeneous” space: “We must thus distinguish between the perception of extensity and the conception of space.... [S]pace is not so homogeneous for the animal as for us... determinations of space, or directions, do not assume for it a purely geometrical form” [Bergson, Time... (shrink)

Linear regression and its variants have been widely used for classification problems. However, they usually predefine a strict binary label matrix which has no freedom to fit the samples. In addition, they cannot deal with complex real-world applications such as the case of face recognition where samples may not be linearly separable owing to varying poses, expressions, and illumination conditions. Therefore, in this paper, we propose the kernel negative ε dragging linear regression method for robust classification on noised and (...) nonlinear data. First, a technique called negative ε dragging is introduced for relaxing class labels and is integrated into the LR model for classification to properly treat the class margin of conventional linear regressions for obtaining robust result. Then, the data is implicitly mapped into a high dimensional kernel space by using the nonlinear mapping determined by a kernel function to make the data more linearly separable. Finally, our obtained KNDLR method is able to partially alleviate the problem of overfitting and can perform classification well for noised and deformable data. Experimental results show that the KNDLR classification algorithm obtains greater generalization performance and leads to better robust classification decision. (shrink)

Aiming to improve the commercialization efficiency of scientific innovative achievements, this paper utilizes the time series visualization method to construct the time series network of each subsystem. After that, the network similarity is calculated by the cosine similarity theorem. On this basis, a new multilayer network adjacency matrix is obtained. With the adoption of k-core technology, the critical nodes can be identified to study the transformation efficiency of the innovation value in the network. Finally, according to the provincial innovation (...) value transformation data of China from 1998 to 2016, an empirical study was carried out to calculate and analyze the transformation efficiency of innovation achievements in 30 provinces. The results indicate that the transformation efficiency of innovation value can be expressed by the structure of the time series network constructed by the input-output vectors; the mapping relationship of the value transformation vectors could be reflected by the cosine similarity of the time series network, while the transformation efficiency of innovation value could be identified using the k-core; and the transformation efficiency of innovation value in three coastal provinces is relatively higher, while that of the rest of the provinces is roughly the same among the 30 provinces.

This study aimed to explore practices and strategies that have successfully reduced time-to-proficiency of the workforce in large multinational organisations and develop a model based on them. The central research question of this study was: How can organisations accelerate time-to-proficiency of employees in the workplace? The study addressed three aspects: the meaning of accelerated proficiency, as seen by business leaders; the business factors driving the need for shorter time-to-proficiency and benefits accrued from it; and practices and strategies to shorten time-to-proficiency (...) of the workforce. 85 participants (n=85) from 7 countries who represented 10 economic sectors, 20 business sectors and 28 industry groups contributed 66 successful bounded project cases. A qualitative research approach was used. Data were collected through in-depth interviews with project leaders and by collecting additional project case documents. Data were analysed using thematic analysis to identify the themes in the data. Matrix analysis was then used to perform within-case and cross-case analysis to compare the project cases. 11 overarching themes were developed from the data analysis, out of which two overarching themes explained the characteristics of job-role proficiency and accelerated proficiency, while three overarching themes described the magnituide and scale of time-to-proficiency business problem, business drivers for accelerating proficiency and business benefits of reduced time-to-proficiency. Six overarching themes revealed the business practices employed by organisations to reduce time-to-proficiency: (1) Defining business-driven proficiency measures in terms of expected business outcomes from a job role; (2) Developing a proficiency reference map of all the inputs, conditions and roadblocks that determine or influence how required business outcomes are being produced in a job role; (3) Sequencing an efficient proficiency path of activities and experiences ordered to produce the desired business outcomes in the shortest possible time; (4) Manufacturing accelerated contextual experiences by leveraging on-the-job opportunities or training interventions in a compressed time-frame; (5) Promoting an active emotional immersion through engagements, consequences, stakes, feedback and proficiency assessments; and (6) Setting up a proficiency eco-system, providing timely support to performers while doing the job such as enabling job environment, highly involved manager, structured mentoring from experts, purposeful social connectivity with peers, leveraging subject matter experts and on-demand performance support systems. Organisations orchestrated these six business practices as an input-output-feedback system to reduce time-to-proficiency of the workforce. A conceptual model (Accelerated Proficiency Model) was developed representing interactions among six business-level practices/processes as a closed-loop system to explain the concept and process of accelerated proficiency in the workplace. These practices were implemented through a set of twenty-four strategies proven successful in various contexts. The strategies employed were much beyond the boundaries of conventional training interventions. The job itself acted as the primary mechanism to accelerate proficiency. A two-level hierarchical framework (6/24 framework of strategies) was also constructed in the form of a checklist consisting of six practices and twenty-four strategies for practitioners. Overall, the findings of this research study contribute significantly to the body of knowledge on accelerated proficiency. In particular, the conceptual model and the framework developed in this study can be implemented across a range of contexts, business sectors, job types and settings to reduce time-to-proficiency of the workforce.

The concept of time emerges as an ordering structure in a classical statistical ensemble. Probability distributions p τ (t) at a given time t obtain by integrating out the past and future. We discuss all-time probability distributions that realize a unitary time evolution as described by rotations of the real wave function $q_{\tau}(t)=\pm \sqrt{p_{\tau}(t)}$ . We establish a map to quantum physics and the Schrödinger equation. Suitable classical observables are mapped to quantum operators. The non-commutativity of the operator product is (...) traced back to the incomplete statistics of the local-time subsystem. Our investigation of classical statistics is based on two-level observables that take the values one or zero. Then the wave functions can be mapped to elements of a Grassmann algebra. Quantum field theories for fermions arise naturally from our formulation of probabilistic time. (shrink)

Significant efforts have been made to define ethical responsibilities for professionals engaged in nanotechnology innovation. Rosalyn Berne delineated three ethical dimensions of nanotechnological innovation: non-negotiable concerns, negotiable socio-cultural claims, and tacitly ingrained norms. Braden Allenby demarcated three levels of responsibility: the individual, professional societies (e.g. engineering codes), and the macro-ethical. This article will explore how these definitions of responsibility map onto practitioners’ understanding of their responsibilities and the responsibilities of others using the nanotechnology innovation community of the greater Phoenix area, (...) which includes academic researchers, investors, entrepreneurs, manufacturers, insurers, attorneys, buyers, and media. To do this we develop a three-by-three matrix that combines Berne’s three dimensions and Allenby’s three levels. We then categorize the ethical responsibilities expressed by forty-five practitioners in semi-structured interviews using these published dimensions and levels. Two questions guide the research: (i) what responsibilities do actors express as theirs and/or assign to other actors and; (ii) can those responsibilities be mapped to the presented ethical frameworks? We found that most of the responsibilities outlined by our respondents concentrate at the professional society + non-negotiable and professional + negotiable intersections. The study moves from a philosophical exploration of ethics to an empirical analysis, exploring strengths, weaknesses, and gaps in the existing nanotechnology innovation network. This opens the door for new practitioners to be introduced in an effort to address responsibilities that are not currently recognized. (shrink)

Walter Map was a twelfth-century courtier and royal servant. He was a prolific writer, but De Nugis Curialium is the only surviving work confidently attributed to him. The book is a collection of short stories and anecdotes about the court, religion and history. Map's references demonstrate that he read widely, not only biblical and theological works, but also classical authors such as Horace, Virgil, Ovid and Juvenal. The only surviving manuscript of the work is a fourteenth-century copy once belonging to (...) the monk John Wells of Ramsey Abbey. The Cambridge bibliographer M. R. James would have been attracted to the breadth of Map's referencing, and the author's light-hearted writing style which was intended to entertain. James' 1914 Oxford publication corrected the earlier work of Thomas Wright who published an edition for the Camden Society in 1850. (shrink)
