In this article, we describe and attempt to solve a puzzle arising from the interpretation of modified numerals like less than five and between two and five. The puzzle is this: such modified numerals seem to mean different things depending on whether they combine with distributive or non-distributive predicates. When they combine with distributive predicates, they intuitively impose a kind of upper bound, whereas when they combine with non-distributive predicates, they do not. We propose and explore (...) in detail four solutions to this puzzle, each involving some notion of maximality, but differing in the type of maximality involved and in the source of maximality. While the full range of data we consider do not conclusively favor one theory over the other three, we do argue that overall the evidence goes against the view that modified numerals lexically encode a ‘standard’ maximality operator, and suggests the need for a pragmatic blocking mechanism that filters out readings of sentences that are generated by the grammar but intuitively unavailable.

We present a number of puzzles arising for the interpretation of modified numerals. Following Büring and others we assume that the main difference between comparative and superlative modifiers is that only the latter convey disjunctive meanings. We further argue that the inference patterns triggered by disjunction and superlative modifiers are hard to capture in existing semantic and pragmatic analyses of these phenomena (neo-Gricean or grammatical alike), and we propose a novel account of these inferences in the framework of (...) bilateral state-based modal logic defining a first order extension of Aloni (Semant Pragmat 15:5-EA, 2022. https://doi.org/10.3765/sp.15.5)’s.

Modified numerals, such as at least three and more than five, are known to sometimes give rise to ignorance inferences. However, there is disagreement in the literature regarding the nature of these inferences, their context dependence, and differences between at least and more than. We present a series of experiments which sheds new light on these issues. Our results show that the ignorance inferences of at least are more robust than those of more than, the presence and strength (...) of the ignorance inferences triggered by both at least and more than depends on the question under discussion, and whether ignorance inferences are detected in a given experimental setting depends partly on the task that participants are asked to perform. We offer an Optimality Theoretic account of these findings. In particular, the task effect is captured by assuming that in performing an acceptability task, participants take the speaker’s perspective in order to determine whether an expression is optimal given a certain epistemic state, while in performing an inference task they take the addressee’s perspective in order to determine what the most likely epistemic state of the speaker is given a certain expression. To execute the latter task in a fully rational manner, participants have to perform higher-order reasoning about alternative expressions the speaker could have used. Under the assumption that participants do not always perform such higher-order reasoning but also often resort to so-called unidirectional optimization, the task effect finds a natural explanation. This also allows us to relate our finding to asymmetries between comprehension and production that have been found in language acquisition. (shrink)

The advantages and risks of a number of new genome modifying procedures seeking to create healthy or enhanced individuals, such as Maternal Spindle Transfer, Pronuclear Transfer, Cytoplasmic Transfer and Genome Editing, are currently being assessed from an ethical perspective, by national and international policy organizations. One important aspect being examined concerns the effects of these procedures on different kinds of identity. In other words, whether or not a procedure only modifies the qualities or properties of an existing human being, meaning (...) that merely the qualitative identity of this single individual is affected, or whether a procedure results in the creation of a new individual, meaning that a numerically distinct human being would have come into existence. In this article, the different identity arguments proposed, so far, are presented with respect to these novel reproductive procedures. An alternative view is then developed using the Origin Essentialism argument to indicate that any change in the creative conditions of an individual such as in his or her biology but also the moment in time, and the three dimensions of space, will have a numerical identity effect and bring into existence a new individual who would not, otherwise, have existed. Because of this, it is concluded that a form of selection may have taken place in which a preference was expressed for one new possible individual instead of another, based on some frame of reference. This may then mean that a selection between persons has occured contravening the European Union Charter of Fundamental Rights which was ratified in 2000. (shrink)

Advocates of linguistic pragmatics often appeal to a principle which Paul Grice called Modified Occam's Razor: 'Senses are not to be multiplied beyond necessity'. Superficially, Grice's principle seems a routine application of the principle of parsimony ('Entities are not to be multiplied beyond necessity'). But parsimony arguments, though common in science, are notoriously problematic, and their use by Griceans faces numerous objections. This paper argues that Modified Occam's Razor makes considerably more sense in light of certain assumptions about (...) the processes involved in language acquisition, and it describes recent empirical findings that bear these assumptions out. The resulting account solves several difficulties that otherwise confront Grice's principle, and it draws attention to problematic assumptions involved in using parsimony to argue for pragmatic accounts of linguistic phenomena.

The pigeon-inspired optimization algorithm is a category of a newly proposed swarm intelligence-based algorithm that belongs to the population-based solution technique. The MKP is a class of complex optimization problems that have many practical applications in the fields of engineering and sciences. Due to the practical applications of MKP, numerous algorithmic-based methods like local search and population-based search algorithms have been proposed to solve the MKP in the past few decades. This paper proposes a modified binary pigeon-inspired optimization algorithm (...) named (Modified-BPIO) for the 0 - 1 multidimensional knapsack problem (MKP). The utilization of the binary pigeon-inspired optimization (BPIO) for solving the multidimensional knapsack problem came with huge success. However, it can be observed that the BPIO converges prematurely due to lost diversity during the search activities. Given the above, the crossover operator is integrated with the landmark component of the BPIO to improve the diversity of the solution space. The MKP benchmarks from the Operations Research (OR) library are utilized to test the performance of the proposed binary method. Experimentally, it is concluded that the proposed Modified-BPIO has a better performance when compared with the BPIO and existing state-of-the-arts that worked on the same MKP benchmarks. (shrink)

Metaheuristic algorithms are often applied to global function optimization problems. To overcome the poor real-time performance and low precision of the basic salp swarm algorithm, this paper introduces a novel hybrid algorithm inspired by the perturbation weight mechanism. The proposed perturbation weight salp swarm algorithm has the advantages of a broad search scope and a strong balance between exploration and exploitation and retains a relatively low computational complexity when dealing with numerous large-scale problems. A new coefficient factor is introduced to (...) the basic salp swarm algorithm, and new update strategies for the leader position and the followers are introduced in the search phase. The new leader position updating strategy has a specific bounded scope and strong search performance, thus accelerating the iteration process. The new follower updating strategy maintains the diversity of feasible solutions while reducing the computational load. This paper describes the application of the proposed algorithm to low-dimension and variable-dimension functions. This paper also presents iteration curves, box-plot charts, and search-path graphics to verify the accuracy of the proposed algorithm. The experimental results demonstrate that the perturbation weight salp swarm algorithm offers a better search speed and search balance than the basic salp swarm algorithm in different environments.

This paper examines the nature of classical correspondence in the case of coherent states at the level of quantum trajectories. We first show that for a harmonic oscillator, the coherent state complex quantum trajectories and the complex classical trajectories are identical to each other. This congruence in the complex plane, not restricted to high quantum numbers alone, illustrates that the harmonic oscillator in a coherent state executes classical motion. The quantum trajectories we consider are those conceived in a modified (...) de Broglie-Bohm scheme. Though quantum trajectory representations are widely discussed in recent years, identical classical and quantum trajectories for coherent states are obtained only in the present approach. We may note that this result for standard harmonic oscillator coherent states is not totally unexpected because of their holomorphic nature. The study is extended to coherent states of a particle in an infinite potential well and that in a symmetric Poschl-Teller potential by solving for the trajectories numerically. For the Gazeau-Klauder coherent state of the infinite potential well, almost identical classical and quantum trajectories are obtained whereas for the Poschl-Teller potential, though classical trajectories are not regained, a periodic motion results as t→∞. Similar features were found for the SUSY quantum mechanics-based coherent states of the Poschl-Teller potential too, but this time the pattern of complex trajectories is quite different from that of the previous case. Thus we find that the method is a potential tool in analyzing the properties of generalized coherent states. (shrink)

Criteria for the transtemporal identity of composite artifacts are best understood in terms of functions, histories, and the intentions their makers. As long as certain background-conditions are fulfilled, composite artifacts can undergo changes in all of their parts with no breakdown in their identities, even to the point of being unrecognizable as sharing their identities with themselves as they were originally constituted. They can be repaired, modified, or improved without a resulting breakdown of transitivity. I defend this view against (...) views according to which there must be some limit to how much change artifacts can undergo while still retaining their identities, against views according to which any changes result in breakdowns of transitivity, and against views according to which there are no criteria of identity over time.

In Science Without Numbers (1980), Hartry Field defends a theory of quantity that, he claims, is able to provide both i) an intrinsic explanation of the structure of space, spacetime, and other quantitative properties, and ii) an intrinsic explanation of why certain numerical representations of quantities (distances, lengths, mass, temperature, etc.) are appropriate or acceptable while others are not. But several philosophers have argued otherwise. In this paper I focus on arguments from Ellis and Milne to the effect that one (...) cannot provide an account of quantity in ''purely intrinsic'' terms. I show, first, that these arguments are confused. Second, I show that Field's treatment of quantity can provide an intrinsic explanation of the structure of quantitative properties; what it cannot do is provide an intrinsic explanation of why certain numerical representations are more appropriate than others. Third, I show that one could provide an intrinsic explanation of this sort if one modified Field's account in certain ways. (shrink)

Science is the basis for managing the affairs of life and human activities, and living without knowledge is a form of wandering and a kind of loss. Using scientific methods helps us understand the foundations of choice, decision-making, and adopting the right solutions when solutions abound and options are numerous. Operational research is considered the best that scientific development has provided because its methods depend on the application of scientific methods in solving complex issues and the optimal use of available (...) resources in various fields, private and governmental work in peace and war, in politics and economics, in planning and implementation, and in various aspects of life. Its basic essence is to use the data provided for the issue under study to build a mathematical model that is the optimal solution. It is the basis on which decision makers rely in managing institutions and companies, and when operations research methods meet with the neutrosophic teacher, we get ideal solutions that take into account all the circumstances and fluctuations that may occur in the work environment over time. One of the most important operations research methods is the linear programming method. Which prompted us to reformulate the linear models, the graphical method, and the simplex method, which are used to obtain the optimal solution for linear models using the concepts of neutrosophic science. In this research, and as a continuation of what we presented previously, we will reformulate the modified simplex algorithm that was presented to address the difficulty that we were facing when applying the direct simplex algorithm. It is the large number of calculations required to be performed in each step of the solution, which requires a lot of time and effort. (shrink)

In this study, we implemented a new numerical method known as the Chebyshev Pseudospectral method for solving nonlinear delay differential equations having fractional order. The fractional derivative is defined in Caputo manner. The proposed method is simple, effective, and straightforward as compared to other numerical techniques. To check the validity and accuracy of the proposed method, some illustrative examples are solved by using the present scenario. The obtained results have confirmed the greater accuracy than the modified Laguerre wavelet method, (...) the Chebyshev wavelet method, and the modified wavelet-based algorithm. Moreover, based on the novelty and scientific importance, the present method can be extended to solve other nonlinear fractional-order delay differential equations. (shrink)

The paper concerns the expression of non-strict comparison, focusing in particular on constructions of the form [no(t) . . .-er than] in modified numerals. The main empirical finding is the observation that negated comparatives contrast with regular comparatives in that the former but not the latter can give rise to (scalar) implicatures. It is shown that such a contrast falls out of theories of exhaustive interpretation that claim alternatives to form dense scales. An important result is that the (...) paper sharpens the desiderata for theories of exhaustification. (shrink)

Organic evolution, or change, among the diatoms has proceeded with considerable regularity. The origins, the extinctions, and the increases in numbers of species and genera, on the whole, have submitted to law and order, as rules-within-limits . The changes of evolution have followed from two sorts of phenomena — 1) the origin and extinction of shortlived or unstable species, in a proportion which has been more or less constant, but different in the two groups of diatoms, Centricae and Pennatae; these (...) short-lived species died out in the subperiod of their origin even under favourable enough environment or surrounding conditions, because of the innate instability of these particular species: and 2) the origin of new species which demonstrated their innate capacity for permanence by remaining in the living condition from their origins mostly up to the present time. The continued or continual additions of new and long-living species, in proportion to the number available as possible and parental species, has given the geometrical progressions.Consequently evolution in the diatoms has been monopodial, or one-stemmed, and not sympodial or not with many substitutions of one species after another in successions. The two kinds of species-durations are well-known in other classes of plants and animals. Exactly the same processes of additions, subtractions, and multiplications, particularly as found in the centric diatoms, are very probable in these classes of plants and animals which have given the same answer or arithmetical result for the whole of their previous histories, in the form of the frequency distribution of the present sizes of their genera.The rules-within-limits of this basic evolution are described, defined, and discussed in their relations to various theories of evolution which perhaps only concern the working of factors of superimposed modifications that reduce the results of the pattern or plan of basic evolution.Die phylogenetische Entwicklung wurde im Bereich der Kieselalgen von bestimmten Gesetzmässigkeiten beherrscht. Die Entstehung neuer Arten und Gattungen, ihr Wiederverschwinden und die Zunahme des Formenreichtums, resultierend aus der Zahl der neuentstandenen, vermindert um die der wieder verschwindenen Arten und Gattungen und vollzog sich nach Regeln , die durch folgende Phänomene gekennzeichnet sind: Zwischen der Zahl der neuentstehenden und der Zahl der in der gleichen geologischen Subperiode aus inneren Gründen wieder aussterbenden Arten besteht eine mehr oder wenig feste Beziehung. Diese ist für die Centricae und Pennatae verschieden. Ein bestimmter Anteil der neuentstandenen Arten und Gattungen erwies sich aus inneren Gründen als „ausdauernd” und blieb bis auf den heutigen Tag erhalten. Die Zunahme der Arten- Zahl durch das Hinzukommen langlebiger Formen war stetig und vollzog sich nach Massgabe geometrischer Progressionen.Diese Tatsachen führen zu dem Schluss, dass die phylogenetische Entwicklung der Kieselalgen nach monopodialem, und nicht nach sympodialem Muster vorsichging. Auch in andern Pflanzengruppen und im Tierreich durften die gleichen Gesetzmässigkeiten herrschend sein. Am klarsten gelangen sie bei den Centricae zum, Ausdruck und werden vom Autor als das Fazit von Additions-, Subtraktions-, und Multiplikationsprozessen aufgefasst. Die heutige Situation bezüglich Häufigkeit der Grössen der Gattungen, in Zahl der Arten, ist das Endergebnis der summativen Wirkung dieser Einzelprozesse.Diese als ‚rules-within-limits’ bezeichneten Gesetzmässigkeiten werden im einzelnen beschrieben, erklärt und zusammenfassend dargestellt. Zu andern Evolutionstheorien in Beziehung gebracht, werden sie schliesslich für Erörterung des Problems benutzt, inwieweit noch andere evolutionsgeschichtliche Prozesse als übergeordnete Faktoren in den vom Verfasser dargestellten Grundplan des Evolutionsgeschehens eingreifen können.L'évolution organique ou le changement parmi les Diatomées s'est effectué avec une régularité considérable. Les origines et les extinctions, et les accroissements des nombres des espèces et des genres, se sont soumis en tout aux lois et aux ordres, commes des régularités à l'intérieur de légères déviations. Le changement de l'évolution fut la conséquence de deux sortes de phénomène: l'origine et l'extinction des espèces éphémères dans une proportion plus ou moins déterminée mais différente pour les deux classes des Diatomées, Centricae et Pennatae; ces espèces éphémères moururent dans la subpériode de leur origines malgré le caractère assez favorable des circonstances environnantes, à cause de l'évanescence inhérente aux espèces particulières, et l'origine des espèces nouvelles qui démontrèrent leur qualité innée de permanence tout en continuant de vivre depuis leurs origines, pour la plupart, jusqu'à présent. Les additions continuelles d'espèces nouvelles et permanentes, en nombres proportionnés aux nombres disponibles comme espèces parentes et possibles, donnèrent des accroissements par progressions géométriques.Par conséquent, l'évolution parmi les Diatomées fut monopodiale et non pas sympodiale. Les deux sortes d'espèces-durées sont bien connues parmi beaucoup d'autres classes de plantes et d'animaux. Les mêmes procédés d'additions, de soustractions et de multiplications, particulièrement tels qu'on les trouve dans les Centricae, sont très probables pour ces classes de plantes et d'animaux qui ont donné un résultat le plus semblable pour la somme totale de leur histoire précédente, sous la forme de la répartition des fréquences de leurs grandeurs générique actuelles.Les régularités à l'intérieur de légères déviations de cette évolution fondamentale sont détaillées, définies et discutées dans leurs relations aux diverses théories touchant les autres méthodes de l'évolution qui jouent le rôle de facteurs modifiants superposés au dessin général ou au dessein de l'évolution fondamentale.

A paradox adapted from the well-known 'paradox of increase ' has been formulated against composite Christology in recent literature. I argue that concrete -composite Christologists can reply by denying the premise that the pre-incarnate divine nature = the Second Person of the Trinity. This denial can be made by modifying a hylomorphic theory of individuals. Using an analogy from material coinciding objects, this modified theory provides an illuminating account of how a person can gain parts over time but remain (...) numerically identical, and it demonstrates that concrete nature and person are not the same thing.

Lying for a strategic advantage is to be expected in commercial interactions. But would this be more or less obvious when lying could come from either party and question mutually profitable exchange? To explore this, we modify the acquiring-a-company game by letting both, buyer and seller, be privately informed. Specifically, the value of the company for the buyer is known only by the seller; whereas, only the buyer is aware by which proportion the sellers evaluation is lower than that of (...) the buyer. Before bargaining, both parties can reveal what they know via cheap-talk numerical messages. Game theoretically, the pooling equilibrium may or may not allow for trade depending on the commonly known expected evaluation discrepancy. By mutually revealing what one knows, one could boost trade and efficiency. Although strategic misreporting prevails quite generally, it is higher for sellers throughout the experiment. Regarding gender, women misreport less, especially as sellers, and offer higher prices. (shrink)

This book surveys research in quantification starting with the foundational work in the 1970s. It paints a vivid picture of generalized quantifiers and Boolean semantics. It explains how the discovery of diverse scope behavior in the 1990s transformed the view of quantification, and how the study of the internal composition of quantifiers has become central in recent years. It presents different approaches to the same problems, and links modern logic and formal semantics to advances in generative syntax. A unique feature (...) of the book is that it systematically brings cross-linguistic data to bear on the theoretical issues, discussing French, German, Dutch, Hungarian, Russian, Japanese, Telugu (Dravidian), and Shupamem (Grassfield Bantu), and pointing to formal semantic literature involving quantification in around thirty languages. -- -/- 1.

Disjunctions in the scope of possibility modals give rise to a conjunctive inference, generally referred to as ‘free choice.’ For example, Emma can take Spanish or Calculus suggests that Emma can take Spanish and can take Calculus. This inference is not valid on standard semantics for modals in combination with a Boolean semantics for disjunction. Hence free choice has sparked a whole industry of theories in philosophy of language and semantics. This paper investigates free choice in sentences involving a non-monotonic (...) modified numeral, under which we embed a possibility modal scoping over disjunction. One example is Exactly one student can take Spanish or Calculus. As we point out, the presence of certain readings of these sentences is a key test for a prominent approach, which analyzes free choice as a kind of scalar implicature. We report on two experiments investigating the readings of such sentences, using an inferential task. Our results are challenging for the implicature approach. We sketch two possible solutions within this approach, either adopting a different recent implicature algorithm, or exploring a different meaning for modified numerals with exactly. Both of them suffer from a variety of problems. We then discuss a third solution, which exploits a recent account of free choice based on homogeneity. This approach can account for our results, in combination with plausible assumptions about homogeneity projection, though it too has open issues with related cases. Regardless of which solution is chosen, non-monotonic contexts turn out to be an important test case for theories of free choice, implicature, and modified numerals. (shrink)

This paper presents a generalization of the standard notions of left monotonicity (on the nominal argument of a determiner) and right monotonicity (on the VP argument of a determiner). Determiners such as “more than/at least as many as” or “fewer than/at most as many as”, which occur in so-called propositional comparison, are shown to be monotone with respect to two nominal arguments and two VP-arguments. In addition, it is argued that the standard Generalized Quantifier analysis of numerical determiners such as (...) “more than three/at least three” is a simplification which ignores the fundamental parallellism with the propositional comparatives. Furthermore, the symmetric monotonicity configurations of the existential “some” and “no” are shown to be straightforwardly related to those of numerical comparatives with the limit numeral zero, whereas the asymmetric configurations of universal “all” and “not all” involve the extra complicating mechanism of polarity reversal, which is related to Keenan's notion of co-intersectivity (as opposed to intersectivity). A second aim of the paper is to investigate some of the factors reducing the inferential potential of determiners. Different types of comparative determiners and their modification will be considered in detail. In addition, a systematic interaction will be revealed between the monotonicity properties of the determiners in propositional comparatives and the differ ent types of ellipsis in the “than”-complement. Different degrees of ellipsis are defined in terms of informational dependencies between the “than”-complement and the main clause. A general balancing mechanism is observed by virtue of which an increase in informational dependency is compensated by a reduction of the inferential potential of the comparative determiner. The structure of the paper is as follows. Part two deals with propositional comparison and introduces the two basic monotonicity configurations. Part three distinguishes three types of informational dependencies or ellipsis between the “than”-complement and the main clause. In Section 3.1 the “than”-complement only contains a VP constituent, whereas in Section 3.2. it only consists of a nominal constituent. Section 3.3 considers more complex instances of multiple dependencies. Section 3.4 then looks at the interaction of these three types with the modifier “proportionally”. Part four presents the two basic monotonicity configurations for numerical comparison, whereas part five deals with more complex numerical determiners. Bounding determiners, such as “between five and ten”, and other boolean combinations are discussed in Section 5.1, whereas Section 5.2 goes into approximative determiners involving modifiers such as “only” or “almost”. Section 5.3. is devoted to proportional determiners such as “more than two out of three”. Part six then considers the standard existential and universal quantifiers. Section 6.1 reformulates the standard Generalized Quantifier analysis in comparative terms, whereas Section 6.2 deals with exception determiners of the form “all but five”. (shrink)

Despite numerous studies on the treatment of developmental language disorder, the intervention effect has long been debated. Systematic reviews of the effect of language therapy alone are rare. This evidence-based study investigated the effect of language therapy alone for different expressive and receptive language levels in children with DLD. Publications in databases including PubMed, the Cochrane Library, the Wanfang Database and the China National Knowledge Infrastructure were searched. Randomized controlled trials were selected. The methodological quality of the included trials was (...) assessed using the modified Jadad method. RevMan 5.3 software was used for the data analysis. Fifteen trials were included in this study. Compared with the control group, the intervention group showed significant differences in overall expressive language development [standard mean differences, 0.46; 95% confidence interval, 0.12–0.80], mean length of utterances in a language sample, number of utterances in a language sample, parent reports of expressive phrase complexity, overall expressive vocabulary development and different words used in a language sample. However, language therapy did not show satisfactory long-term effects on DLD. Although language therapy is helpful in improving the performance of children with DLD, its long-term effect is unsatisfactory. (shrink)

Numerous definitions of literacy have been advanced by policy‐makers, politicians, academics, teachers and others over the years. It is not always easy, however, to know how one definition might relate to another or differ from it.

Modified to have particular relevance to statements about literacy, the three types of definition are: stipulative, essentialist and prescriptive.

In September 2012, Gilles-Eric Séralini and seven coauthors published an article in Food and Chemical Toxicology claiming that rats fed Roundup©-resistant genetically modified maize alone, genetically modified maize with Roundup©, or Roundup© for 2 years had a higher percentage of tumors and kidney and liver damage than normal controls. Shortly after this study was published, numerous scientists and several scientific organizations criticized the research as methodologically and ethically flawed. In January 2014, the journal retracted the article without the (...) authors’ consent on the grounds that the research was inconclusive. In June 2014, Environmental Sciences Europe published a slightly modified version of the retracted paper. The publication, retraction and subsequent republication of the Séralini study raise important scientific and ethical issues for journal editors. Decisions to retract an article should be made on the basis of well-established policies. Articles should be retracted only for serious errors that undermine the reliability of the data or results, or for serious ethical lapses, such as research misconduct or mistreatment of animal or human subjects. Inconclusiveness, by itself, is not a sufficient reason for retracting an article, though a flawed study design might be. Retracted articles that are submitted for republication should undergo scientific review to ensure that they meet appropriate standards. Republished articles should be linked to the original, retracted publication. Journals that are reviewing studies with significant scientific and social implications should take special care to ensure that peer review is rigorous and fair. (shrink)

The development of the aquaculture industry in Canada has triggered a conflict of a scope never seen before. As stated in Young and Matthews’ The Aquaculture Controversy, this debate has “mushroomed over the past several decades to become one of the most bitter and stubborn face-offs over industrial development ever witnessed in Canada” (Young and Matthews in The aquaculture controversy in Canada. Activism, policy and contested science. UBC Press, Vancouver, p 3, 2010). It opposes a wide variety of actors: from (...) industrial investors, scientists, politicians and environmentalists to Native associations and communities, citizens groups and local stakeholders. The opposition is fierce between those in favor of a flourishing and modern aquaculture of industrial nature and those who fear the dreadful consequences of such an industry. In particular, the possible implementation of biotechnology innovations, such as a genetically modified salmon, has made this debate coextensive with the GMO debate, thus multiplying the opposition’s spectrum of arguments against the industry. Throughout the debate, Canadian environmental NGOs like the Suzuki Foundation and Greenpeace Canada have assumed leadership over the opposition to aquaculture development with certain success. Their participation in the debate features numerous ethical concerns related to environmental health, a respect for wilderness and local human communities. Such a position can be associated overall with a form of ecocentric ethics or concern. Nevertheless, a careful examination of the technical solutions proposed by these NGOs reveals their embeddedness in biocentrism. Through the example taken from the Canadian debate on aquaculture development, this paper aims to highlight the conceptual difficulty of enacting ecocentric ethical positions beyond formal arguments. Because ecocentrism implies a true paradigm shift, not only in mentality, but also in the way we conceive our technical interventions in nature, biocentrism remains an important practical method to enact ethical positions related to environmental concerns in public debates.

Numerous clinical, epidemiological and molecular findings link some types of Human Papillomaviruses (HPV) with cancer of the genital tract. They share a common pathway of transformation with a number of DNA tumour viruses, such as Adenovirus and SV40. Although all these viruses are termed ‘DNA tumour viruses’ and have similar in vitro transforming activities, Human Papillomavirus is the only one so far clearly involved in human cancer. Extensive studies on HPV E6 and E7 proteins have demonstrated their involvement in malignant (...) transformation. E6 and E7 bind the products of tumour suppressor genes, p53 and Rb1, respectively, modifying or inactivating their normal functions. The Rb1 and p53 genes are deleted or mutated in several cancers and both proteins regulate the transcription of genes involved in cell cycle progression control. The E6/p53 and E7/Rb1 interactions result in a deregulation of the cell cycle with loss of control of crucial cellular events, such as DNA replication, DNA repair and apoptosis. (shrink)

Numerous studies indicate that racial minorities are both more likely to be executed for murder and that those who murder them are less likely to be executed than if they murder whites. Death penalty opponents have long attempted to use these studies to argue for a moratorium on capital punishment. Whatever the merits of such arguments, they overlook the fact that such discrimination alters the costs of murder; racial discrimination imposes higher costs on minorities for murdering through tougher sentences, and (...) it imposes lower costs on whites for murdering minorities by dispensing weaker sentences. These cost differentials constitute an injustice not simply to actual minority defendants in capital cases, nor simply to the actual minority victims of murder, but to all members of minority communities. I here offer two arguments for a moratorium on capital punishment: The first draws upon evidence of racial discrimination against minority defendants in capital cases, and claims that such discrimination modifies the costs of murder in such a way that minority individuals do not enjoy equal status under the law. The second draws upon the evidence regarding racial discrimination in relation to the race of victims, and claims that such discrimination modifies the costs of murder in such a way that minority individuals do not enjoy the equal protection of the law. Thus, by not assigning equal costs to murder, the American criminal justice system fails to provide racial minorities the equality under the law and discounts the value of their lives and liberties. A moratorium is the least unjust response to such a social injustice. I also reply to the criticism that a moratorium prevents us from executing deserving murderers. (shrink)

Abstract None of the numerous modern proposals for jus post bellum models has gained wide acceptance. The proposals tend to resemble laundry lists, often enumerated without an obvious and coherent ethical rationale. Recognizing the importance of jus post bellum, this article seeks to move the jus post bellum discourse forward. First, the article constructs a foundation of seven principles for jus post bellum models by modifying and integrating the separate proposals advanced by Bellamy and Evans. Then building on that revised (...) set of foundational principles, this article incorporates selected criteria and research from prior proposals to erect a five-part jus post bellum framework: (1) respect for persons; (2) establish justice; (3) exercise ecological responsibility; (4) engage multinational commitment and support; and (5) maintain progress toward closure. The article concludes by arguing that the proposed jus post bellum model is comprehensive, parsimonious, pragmatic, and has a universally applicable framework analogous to Just War Theory's other two components.

BackgroundThere is numerous literature on mechanisms underlying variability of practice advantages. Literature includes both behavioral and neuroimaging studies. Unfortunately, no studies are focusing on practice in constant conditions to the best of our knowledge. Hence it is essential to assess possible differences in mechanisms of neuroplasticity between constant vs. variable practice conditions. The primary objectives of the study described in this protocol will be: to determine the brain’s structural and functional changes following constant and variable practice conditions in motor learning (...) ; to determine the EEG activation and connectivity between cognitive, sensory, and motor cerebral cortex areas in constant and variable practice conditions and as a function of practice time.MethodsThe study will follow the interventional design with two arms. Fifty participants will be randomly assigned to two groups practicing in constant and variable conditions. CG will be practicing only one pattern of step isometric contractions during unimanual index finger abduction, i.e., 90 trials in all training sessions, whereas VG will practice three different patterns. Each will be practiced 30 times per session in variable conditions. Resting-state fMRI, EEG, and motor task proficiency will be examined before and after practice.DiscussionFindings will enhance our understanding of structural and functional neural changes following practice in constant and variable conditions. Therefore, the study can be considered pure research.Clinical Trial RegistrationStudy registered at clinicaltrials.gov on 9 June 2021.

This paper proposes the modified generalization of the HSS to solve a large and sparse continuous Sylvester equation, improving the efficiency and robustness. The analysis shows that the MGHSS converges to the unique solution of AX + XB = C unconditionally. We also propose an inexact variant of the MGHSS and prove its convergence under certain conditions. Numerical experiments verify the efficiency of the proposed methods.

Background There are numerous ethical challenges that can impact patients and families in the health care setting. This paper reports on the results of a study conducted with a panel of clinical bioethicists in Toronto, Ontario, Canada, the purpose of which was to identify the top ethical challenges facing patients and their families in health care. A modified Delphi study was conducted with twelve clinical bioethicist members of the Clinical Ethics Group of the University of Toronto Joint Centre for (...) Bioethics. The panel was asked the question, what do you think are the top ten ethical challenges that Canadians may face in health care? The panel was asked to rank the top ten ethical challenges throughout the Delphi process and consensus was reached after three rounds. Discussion The top challenge ranked by the group was disagreement between patients/families and health care professionals about treatment decisions. The second highest ranked challenge was waiting lists. The third ranked challenge was access to needed resources for the aged, chronically ill, and mentally ill. Summary Although many of the challenges listed by the panel have received significant public attention, there has been very little attention paid to the top ranked challenge. We propose several steps that can be taken to help address this key challenge. (shrink)

Classifications of animals and plants have long been represented by hierarchical lists of taxa, but occasional authors have drawn diagrammatic versions of their classifications in an attempt to better depict the "natural relationships" of their organisms. Ornithologists in 19th-century Britain produced and pioneered many types of classificatory diagrams, and these fall into three groups: (a) the quinarian systems of Vigors and Swainson (1820s and 1830s); (b) the "maps" of Strickland and Wallace (1840s and 1850s); and (c) the evolutionary diagrams of (...) the post-Darwin authors (1860 on). The quinarians distinguished between affinity and analogy and used both in their classifications, whereas Strickland rejected the quinarians' belief in numerical regularity and their use of analogy. Wallace's "maps" are easily given an evolutionary interpretation, and his approach was taken up and modified by later evolutionary anatomists. Sharpe returned to Strickland's methods and merely appended a superficial evolutionary interpretation. Contrary to common belief systematics has a rich conceptual history, and many of the conceptual developments in 19th-century systematics were made by ornithologists. (shrink)

The secret ballot is considered a central feature of free and fair elections all over the world. While the reasons to uphold it seem to be overwhelming, we argue that the secret ballot is only second-best at best and that a modified version of open voting might prove to be more democratic. Instead of denying the various problems and difficulties that an open system might encounter, we want to offer a genuine proposal that can avoid these numerous pitfalls. After (...) rehearsing the various arguments pro and contra open voting, we draw attention to the role of shame, which has been neglected by both sides in the debate. While shame plays a pivotal role in the democratic argument pro open voting, it also brings out new problems that tell against opening up the vote. This means that, if we want to draw on the democratic potential of open voting, we will have to find a system that minimizes the undesirable effects of shame. In the third and final section, we will formulate a concrete proposal of open voting that we believe is more democratic than the current secret ballot and is able to avoid potential worries. Even if this proves to be highly speculative, it serves as an invitation for further empirical research. (shrink)

Offering a solution to the skeptical puzzle is a central aim of Nozick's sensitivity account of knowledge. It is well-known that this account faces serious problems. However, because of its simplicity and its explanatory power, the sensitivity principle has remained attractive and has been subject to numerous modifications, leading to a of sensitivity accounts. I will object to these accounts, arguing that sensitivity accounts of knowledge face two problems. First, they deliver a far too heterogeneous picture of higher-level beliefs about (...) the truth or falsity of one's own beliefs. Second, this problem carries over to bootstrapping and Moorean reasoning. Some beliefs formed via bootstrapping or Moorean reasoning are insensitive, but some closely related beliefs in even stronger propositions are sensitive. These heterogeneous results regarding sensitivity do not fit with our intuitions about bootstrapping and Moorean reasoning. Thus, neither Nozick's sensitivity account of knowledge nor any of its modified versions can provide the basis for an argument that bootstrapping and Moorean reasoning are flawed or for an explanation why they seem to be flawed.

There are numerous well-documented problems with the DSM’s polythetic-categorical approach to the delineation of mental disorders. However, the DSM-5 introduces an empirically based dimensional model of personality traits. These traits form a hierarchical structure that represents the organization of dispositions to common mental disorders. We connect emotions to this joint hierarchical structure using a modified set point model, which accommodates major theories linking personality and psychopathology—continuum, risk, scar, and pathoplasty—as well as more dynamic multivariate models. We argue that these (...) traits represent typical causal pathways that can be extracted from a complex web of equifinality and multifinality. Ultimately, research on mood disorders provides a stronger account of their underling traits than the variably endorsed symptoms of their polythetic criteria. (shrink)

Prawitz observed that Russell’s paradox in naive set theory yields a derivation of absurdity whose reduction sequence loops. Building on this observation, and based on numerous examples, Tennant claimed that this looping feature, or more generally, the fact that derivations of absurdity do not normalize, is characteristic of the paradoxes. Striking results by Ekman show that looping reduction sequences are already obtained in minimal propositional logic, when certain reduction steps, which are prima facie plausible, are considered in addition to the (...) standard ones. This shows that the notion of reduction is in need of clarification. Referring to the notion of identity of proofs in general proof theory, we argue that reduction steps should not merely remove redundancies, but must respect the identity of proofs. Consequentially, we propose to modify Tennant’s paradoxicality test by basing it on this refined notion of reduction. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:488 HISTORY OF PHILOSOPHY most extensive study of this aspect of Schelling's thought, at least until 1806. However, even if Schelling was not, as it is frequently stated, indifferent to the problems and the vicissitudes of politics, his theoretical thinking on this subject never went beyond temporary systematizations, to be given up, or modified, after a while. The author shows how Schelling, especially in this fieM, was influenced (...) either by his environment in general, or by some personalities he happened to contact: first his "republican" and francofile friends of the Ttibingen Stilt, afterwards the romantic circle of Jena, and, between 1801 and 1803, Hegel. The author studies in his first chapter, devoted tO the non-philosophic writings of the TUbingen period (1790-1795), not only Kant's and Herder's influence on Schelling, which are usually taken for granted, but also the impact of C. G. Heine and of other GSttingen scholars. This is a stimulating suggestion, showing the need for a more detailed study on the diffusion of the "historicocritical" method in circles, as the Ttibingen school, dominated rather by philosophical and theological than by philological and historical interests. In the following chapters, Schelling is closely related again to the intellectual history of his time; Schelling's relationship to the Aufkliirer Nicolai produces some surprises, and the same may be said about some new particulars (implementing F. Rosenzweig's and F. Bthm's research) on the close connection between Schelling and Htlderlin in 1795-1796. The fourth chapter is devoted to the correlation between theories on "natural philosophy" and moral political theories. The fifth concerns the philosophy of history and of government. This remarkable study, founded on sound scholarship, and conducted with a sharp historical mind, is to be recommended not only to students of Schelling, but to all those who have some interest in early XIXth Century German political thought. GIORGIO TONELLI State University of New York at Binghamton Gesammelte Werke, Vol. IV. By Georg Wilhelm Friedrich Hegel. Ed. Hartmut Buehner and Otto Ptggeler. (Hamburg: Felix Meiner, 1968. Pp. 622. DM 86.00) Despite the high reputation Germany has long enjoyed with regard to its scientifically reliable editions, up to this very moment, a historic-critical edition of the totality of Hegel's works has not existed. There were only provisional texts of single works available whose philological reliability differed in its sometimes doubtful variety. This is a rather strange fact, considering that Hegel died in 1831. It can be explained only by a phenomenon peculiar to this philosopher: at the peak of his fame, numerous students from all countries of the world attended Hegel's lectures, assiduously taking notes and frequently publishing as authentic what they had understood and jotted down. The philosopher was very generotis in authorizing various versions of his lectures and thus, the international market was swamped with quite incongruous editions of some of his writings at the moment of Hegel's death. Despite this rather confused state of affairs, distinguished scholars have tried, for BOOK REVIEWS 489 more than six decades, to bring order into the posthumous manuscripts of the philosopher, and these efforts were successful, but only to a certain extent. Next to the pioneering publications of Wilhelm Dilthey, Herman Nohl and Frans Rosenzweig, lesser known savants, in the first place, Georg Lasson and Johannes Hoffmeister have devoted many years of self-denying efforts to make /mportant parts of Hegel's manuscripts available to the public and looked for new possibilities to edit the large body of lectures. But the task proved too difficult for individual scholars. For this reason, the Deutsche Forschungsgemeinschaft, a government-sponsored organization, has commissioned the publication of an all-encompassing historic-critical edition of Hegel's works and arranged for the appointment of a senatorial commission for advising the editors of such a mammoth undertaking. Members of the commission were the aforementioned scholars (see title) and W. Wieland. The Ministry of Education of the State of Nordrhein-Westfalen has opened a research center, originally directed by F. Nicolin, since 1968 by O. Ptggeler. Thus the edition can now be published continuously. Before discussing the contents of volume four, the only volume hitherto published, let's take... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Feminist Studies 41, no. 3. © 2015 by Feminist Studies, Inc. 571 Moving through Cancer: An Interview with Carol Collins Artist Carol Collins spoke with Feminist Studies editorial collective member Stephanie Gilmore about her experience of cancer, treatment, and recovery and how it gave rise to an art series that examines what nature means in the midst of unnatural treatments. SG: Carol, thank you for the opportunity to speak (...) with you about your artwork. Having just lost my sister to cancer, your work reminds me of much pain and loss, but also of love and the desire to survive. Before we discuss the work itself, I would like to hear about your journey through cancer, treatment, and recovery. CC: The breast cancer patient’s journey is complex and perilous. When I was healthy, I was ignorant about the magnitude of suffering many cancer patients undergo. And, although I am a private person, I’m now publicly sharing my cancer experience in order to be a voice for those who have suffered through similar treatments—and worse—and those who sadly are no longer with us to tell their story. Being bald and nauseated are not the most awful possible side effects of the treatments, although they are the most well known. Some women survive the cancer but can die from the treatments, or others suffer through the treatments and die anyway. Often, it seems many believe patients can overcome their 572 Carol Collins adversity solely with positive thinking and persistence. However, not discussing the array of physical and psychological damage that even those with good prognoses incur propagates ignorance about this malady. I hope that my artwork and story will promote a deeper understanding of a breast cancer patient’s plight and will encourage more support for research for individualized therapies and prevention. My cancer journey began when I received a breast cancer diagnosis in January 2014. Life just before that point was good; the future was bright. Tendon pain, caused by my flat feet and a lot of exercising, was my only known ailment. But one day a routine mammogram revealed three tumors in my right breast. The radiology oncologist said the masses were highly likely to be cancerous, so he immediately did painful core biopsies at the sites of my three tumors. The next day, it became clear that we needed to act quickly. The biopsy results revealed I had a very aggressive invasive breast cancer with estrogen, progesterone, and HER2 receptors. Breast cancer in premenopausal women grows quickly due to the high level of hormones present. The oncologists and surgeons said I would, at a minimum, need a mastectomy and possibly lymph node resection, and they warned that I would likely need chemotherapy, which would destroy my eggs and ovaries. After learning of my limited options, I approved the removal of one breast and my sterilization. I knew I needed to think rationally and face the giant raven before me head on. However, I did not realize the magnitude and multitude of physical and psychological pains, illnesses, and losses that were soon to come. The first year of cancer treatments inflicted much physical pain. I received three extremely painful injections into my right breast with a radiolabeled colloid just prior to the mastectomy. The pain came from the injected dye, not from the needle. The modified radical mastectomy was more excruciatingly painful than I anticipated, even with painkillers and overnight hospitalization. Breast reconstruction was an option that added more pain and discomfort from weekly fillings of the installed “expander” and additional surgeries. Extreme pain after the mastectomy prevented me from lying down for months. Foolishly, I did not get an injection port installed in my chest. Instead, I endured numerous deep (and often unsuccessful) needle pricks into the seemingly few veins of my left arm (which still had its lymph nodes) that were appropriate for infusions over the period of a year. Shooting pains across my chest and arm were the norm. Carol Collins 573 In addition to the surgically induced physical pain, the chemotherapy quickly caused a myriad of undesirable physical side effects. It is scary to realize that the medical community does not often fully understand... (shrink)

Since Kit Fine published his famous counter-examples to the modal account of essence, numerous modalists have proposed to avoid the counter-examples by revising the modal account. A sophisticated revision has been put forward by Fabrice Correia. Drawing on themes from Prior’s modality, Correia has introduced a nonstandard conception of metaphysical modality and has proposed to analyze essence in its terms. He has claimed that the analysis is immune to Fine’s counter-examples. In this paper, I argue that there are counter-examples supported (...) by the very intuition underlying Fine’s counter-examples, which are not accommodated by Correia’s account. If my argument is sound, then Correia has not been successful in his defense of modalism. An important corollary of my argument will be that Fine’s consequential conception of essence needs to be modified if it is to capture his own intuitive notion of essence. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Pierre Gassendi (1592–1655): Lettres Latines, and: Pierre Gassendi (1592–1655): Introduction à la vie savanteMargaret J. OslerPierre Gassendi. Pierre Gassendi (1592–1655): Lettres Latines. Edited by Sylvie Taussig. Vol. 1, Traduction. Pp. xxxiv + 622. Vol. 2, Notes. Pp. x + 609.

Pp. 454. € 60,00.The reputation of Pierre Gassendi (...) (1592–1655), the French natural philosopher responsible for recovering Epicurean atomism and hedonism and modifying it to be compatible with Christian theology, has suffered neglect in part because of the difficult Latin in which his works were written. Hence, the publication of translations of large chunks of his work into a modern language is, prima facie, a welcome addition to scholarship in the history of philosophy. Accordingly, the appearance of Sylvie Taussig's translation of Gassendi's Latin correspondence, published in the posthumous Opera omnia (1658), seemed, at first blush, to make an important body of Gassendi's writings accessible to more modern scholars. The three books under review consist of a French translation of Volume 6 of Gassendi's [End Page 489] Opera omnia (the Latin letters to which the title refers); a volume of notes on the letters; and a book about Gassendi's life, based closely on the Latin letters.Pierre Gassendi (1592–1655): Introduction à la vie savante summarizes various aspects of Gassendi's life and career from 1621–1655, the years covered by the published correspondence. Basically summarizing the letters, this book has sections on Gassendi's biography for these years, the nature of the correspondence, Gassendi's science, his Epicurean project, his interactions with various notables, and his role in the history of his time. In fact, the book is little more than a topical analysis of the letters. Despite the inclusion of an extensive—but incomplete—bibliography of scholarship on Gassendi, the notes to Taussig's text refer to the letters but to almost no secondary sources.The same problem characterizes her notes to the letters. Containing 7491 footnotes and filling a volume of 609 pages, the second volume of the Lettres latines contains virtually no mention of the contributions of other scholars. These notes range from the explication of Classical references to political events in Gassendi's lifetime, from scientific and philosophical controversies to the issues of Church governance in Digne where Gassendi was a canon in the cathedral.The devil is in the details, and here the details undermine one's confidence in the project. There are many errors in the notes to the letters. For example, in note 1087, the inventor of logarithms is named 'Brigg' rather than 'Briggs.' There are numerous gaffes in the bibliography in Pierre Gassendi (1592–1655): Introduction à la vie savante. For example, the entry for Steven J. Dick, is 'Dick, St. J.'. The entry for Lynn Sumida Joy is 'Lynn, S. J.'. And the entry for Susanna Åkerman is a mess, obviously because the typesetter was unable to deal with the diacritical mark. Although these points seem trivial, their frequency points to a lack of precision and lack of good proofreading.Unfortunately, these three volumes will not provide a reliable new source for scholars seeking access to Gassendi's writings. The French translation of the letters will provide a shortcut, but they will not eliminate the need to consult the original Latin version.Margaret J.

The accurate annotation of an unknown protein sequence depends on extant data of template sequences. This could be empirical or sets of reference sequences, and provides an exhaustive pool of probable functions. Individual methods of predicting dominant function possess shortcomings such as varying degrees of inter-sequence redundancy, arbitrary domain inclusion thresholds, heterogeneous parameterization protocols, and ill-conditioned input channels. Here, I present a rigorous theoretical derivation of various steps of a generic algorithm that integrates and utilizes several statistical methods to predict (...) the dominant function in unknown protein sequences. The accompanying mathematical proofs, interval definitions, analysis, and numerical computations presented are meant to offer insights not only into the specificity and accuracy of predictions, but also provide details of the operatic mechanisms involved in the integration and its ensuing rigor. The algorithm uses numerically modified raw hidden markov model scores of well defined sets of training sequences and clusters them on the basis of known function. The results are then fed into an artificial neural network, the predictions of which can be refined using the available data. This pipeline is trained recursively and can be used to discern the dominant principal function, and thereby, annotate an unknown protein sequence. Whilst, the approach is complex, the specificity of the final predictions can benefit laboratory workers design their experiments with greater confidence. -/- . (shrink)

The clustering of mixed-attribute data is a vital and challenging issue. The density peaks clustering algorithm brings us a simple and efficient solution, but it mainly focuses on numerical attribute data clustering and cannot be adaptive. In this paper, we studied the adaptive improvement method of such an algorithm and proposed an adaptive mixed-attribute data clustering method based on density peaks called AMDPC. In this algorithm, we used the unified distance metric of mixed-attribute data to construct the distance matrix, calculated (...) the local density based on K-nearest neighbors, and proposed the automatic determination method of cluster centers based on three inflection points. Experimental results on real University of California-Irvine datasets showed that the proposed AMDPC algorithm could realize adaptive clustering of mixed-attribute data, can automatically obtain the correct number of clusters, and improved the clustering accuracy of all datasets by more than 22.58%, by 24.25%, by 28.03%, by 22.5%, and by 10.12% for the Heart, Cleveland, Credit, Acute, and Adult datasets compared to that of the traditional K-prototype algorithm, respectively. It also outperformed a modified density peaks clustering algorithm for mixed-attribute data algorithms. (shrink)

My aim is to consider how private philanthropy – and that of foundations specifically – can better serve its social purposes. What I have to say may strike professionals in the field as naive. Admittedly my perspective is limited, for I have sat only on the grantee side of the desk. But I have also often tried to put myself into the grantor's frame of mind. The impressions gained in that way have been confirmed and modified by numerous recent (...) conversations in preparation for this paper. The heads of foundations with whom I talked, the board members, and program officers, all were warmly forthcoming, forgiving of my naivete, and very helpful. I hope that what may be construed as criticism in what I have to say will not be taken as betrayal of those good offices. I mean it as support and encouragement of the positive intent I found in every instance. When I accepted the invitation to write a paper on moral values and philanthropy, I first reflected on my own experience. I have often been troubled by my own moral standards in dealing with foundations. In nearly every instance, the proposals that I have written have contained an element of exaggeration – a heightening of the importance of the project I was proposing and of the capacity of my institution to carry it out. My end-of-grant follow-up reports have almost always contained exaggerated claims for the project's success. This inflation was not done consciously. It was a tendency learned early in my career from reading other proposals and participating in committees designing projects to be proposed. (shrink)

The agent-relative/agent-neutral distintion is widely and rightly regarded as a philosophically important one. Unfortunately, the distinction is often drawn in different and mutually incompatible ways. The agent-relative/agent-neutral distinction has historically been drawn three main ways: the ‘principle-based distinction’, the ‘reason-statement-based distinction’ and the ‘perspective-based distinction’. Each of these approaches has its own distinctive vices (Sections 1-3). However, a slightly modified version of the historically influential principle-based approach seems to avoid most if not all of these vices (Section 4). The (...) distinction so understood differs from numerous other distinctions with which it might easily be confused (Section 5). Finally, the distinction so drawn is important to normative theorizing for a variety of reasons (Section 6). (shrink)

In this paper, I consider the validity and proper formulation of the only-x-and-y principle, which states, roughly, that whether a later individual, y, is numerically identical to an earlier individual, x, can depend only on facts about x and y and the relationships between them. In the course of my investigation, I distinguish between two classes of physical entities - those that exist in a 'real' sense, and those that exist in a mere Cambridge sense. This distinction is grounded in (...) Peter Geach's distinction between 'real' and mere Cambridge change. I argue in favor of a modified version of the only-x-and-y principle - the qualified only-x-and-y principle - which applies to entities that exist in a 'real' sense, but not to mere Cambridge entities. It is also argued that the plausibility of the qualified only-x-and-y principle has more to do with facts about the nature of causality than with intuitions we have about existence or numerical identity. I finish by considering some traditional objections to the only-x-and-y principle, and conclude that they do not succeed in refuting the qualified only-x-and-y principle. (shrink)

Let G = V G, E G be a molecular graph, where V G and E G are the sets of vertices and edges. A topological index of a molecular graph is a numerical quantity which helps to predict the chemical/physical properties of the molecules.

In this paper, we described a linear time algorithm that computes the Wiener index for acyclic graphs and extended this algorithm for (...) unicyclic graphs. The same algorithms are modified to compute the terminal Wiener index and the Wiener polarity index. All these algorithms compute the indices in time O n. (shrink)

The creation of paraconsistent logics have expanded the boundaries of formal logic by introducing coherent systems that tolerate contradictions without triviality. Thanks to their novel approach and rigorous formalization they have already found many applications in computer science, linguistics and mathematics. As a natural next step, some philosophers have also tried to answer the question if human everyday reasoning could be accurately modelled with paraconsistent logics. The purpose of this article is to argue against the notion that human reasoning is (...) paraconsistent. Numerous findings in the area of cognitive psychology and cognitive neuroscience go against the hypothesis that humans tolerate contradictions in their inferences. Humans experience severe stress and confusion when confronted with contradictions. Experiments on the ways in which humans process contradictions point out that the first thing humans do is remove or modify one of the contradictory statements. From an evolutionary perspective, contradiction is useless and even more dangerous than lack of information because it takes up resources to process. Furthermore, it appears that when logicians, anthropologists or psychologists provide examples of contradictions in human culture and behaviour, their examples very rarely take the form of: \\). Instead, they are often conditional statements, probabilistic judgments, metaphors or seemingly incompatible beliefs. At different points in time humans are definitely able to hold contradictory beliefs, but within one reasoning leading to a particular behaviour, contradiction is never tolerated. (shrink)
