The topology optimization of computer communication network is studied based on improved genetic algorithm, a network optimization design model based on the establishment of network reliability maximization under given cost constraints, and the corresponding improved GA is proposed. In this method, the corresponding computer communication network cost model and computer communication network reliability model are established through a specific project, and the genetic intelligence algorithm is used to solve the cost model and computer (...) communication network reliability model, respectively. It has been proved that GA can solve the complex problems of computer working environment better, which is 80% higher than the general algorithm, and can select the optimal scheme pertinently.

This article mitigates the challenges of previously reported literature by reducing the operating cost and improving the performance of network. A genetic algorithm-based tabu search methodology is proposed to solve the link capacity and traffic allocation problem in a computer communication network. An efficient modern super-heuristic search method is used to influence the fixed cost, delay cost, and variable cost of a link on the total operating cost in the computer communication network are discussed. The article (...) analyses a large number of computer simulation results to verify the effectiveness of the tabu search algorithm for CFA problems and also improves the quality of solutions significantly compared with traditional Lagrange relaxation and subgradient optimization algorithms. The experimental results show that with the increase of the weighted coefficient of variable cost, the proportion of variable cost in the total cost increases from 10 to 35%. The growth is relatively slow, and the fixed cost is still the main component. In addition, due to the increase in the variable cost, the tabu search algorithm will also choose the link with large luxury to reduce the variable cost, which makes the fixed cost slightly increase, while the network delay cost and average delay slightly decrease. The proposed method, when compared with the genetic algorithm, has more advantages for large-scale or heavy-load networks. (shrink)

Traditionally, philosophers have ascribed moral agency almost exclusively to humans. Early writing about moral agency can be traced to Aristotle and Aquinas. In addition to human moral agents, Aristotle discussed the possibility of moral agency of the Greek gods and Aquinas discussed the possibility of moral agency of angels. In the case of angels, a difficulty in ascribing moral agency was that it was suspected that angels did not have enough independence from God to ascribe to the angels genuine moral (...) choices. Recently, new candidates have been suggested for non‐human moral agency. Floridi and Sanders suggest that artificially intelligence programs that meet certain criteria may attain the status of moral agents; they suggest a redefinition of moral agency to clarify the relationship between artificial and human agents. Other philosophers, as well as scholars in Science and Technology Studies, are studying the possibility that artifacts that are not designed to mimic human intelligence still embody a kind of moral agency. For example, there has been a lively discussion about the moral intent and the consequential effects of speed bumps. The connections and distributed intelligence of a network is another candidate being considered for moral agency. These philosophical arguments may have practical consequences for software developers, and for the people affected by computing. In this paper, we will examine ideas about artificial moral agency from the perspective of a software developer. (shrink)

This paper is part of an ongoing study that looks at the development of one component of a community network in a city in upstate New York. ‘Community networks’ refers to the use of computer networking technologies for the benefit of strengthening community goals and needs. The component studied is a youth database. In particular, this article looks at the early phases of this project: how the idea of the database emerged, how the technology was presented to the community, (...) and the community's response to this project. Theories guiding this paper include the social construction of technology theory and social worlds theory. (shrink)

Organizational innovation depends heavily on whether or not communication processes are regulated. Furthermore, social networks represent content-based connectivity of actors in opposition to formal organization. Communication technologies such as e-mail make it possible to continuously maintain the establishment and preserve social networks. Enhancing cooperation in team working processes are the benefits of social networks in dynamic organizations. This article reports on four case studies which focused on teamwork and the structural analysis of e-mail as a communication technology (...) in a mobile phone company. The case studies reveal the impact of computer supported social networks which became mainly apparent through changes in personal communication styles and the establishment of alternative hierarchies in electronic environments.

In this paper, an in-depth study of interactive visual communication of network topology through non-line-of-sight congestion control algorithms is conducted to address the real-time routing problem of adapting to dynamic topologies, and a delay-constrained stochastic routing algorithm is proposed to enable packets to reach GB within the delay threshold in the absence of end-to-end delay information while improving network throughput and reducing network resource consumption. The algorithm requires each sending node to select an available relay set based on the (...) location of its neighbor nodes and channel state and computes transfer probabilities for each node in the relay set combining the remaining delay of the packet with the distance from the relay node to GB. Based on the obtained transfer probability and local channel state, the sending node passes the packet to the relay node. The convergence of the algorithm is proved and its performance is verified by simulation. The first part of the algorithm is based on the greedy algorithm to deploy and locate the network flying platform nodes with the goal of efficient coverage of the network flying platform nodes, considering the ground base station services. As the delay on each link varies due to the change of channel state, the source and relay nodes asynchronously update the data generation rate and the pairwise parameters based on the received local information and use the obtained optimal values to pass the packets to GB.

A brain-computer interface technology that can decode the neural signals associated with attempted but unarticulated speech could offer a future efficient means of communication for people with severe motor impairments. Recent demonstrations have validated this approach. Here we assume that it will be possible in future to decode imagined (i.e., attempted but unarticulated) speech in people with severe motor impairments, and we consider the characteristics that could maximize the social utility of a BCI for communication. As a (...) social interaction, communication involves the needs and goals of both speaker and listener, particularly in contexts that have significant potential consequences. We explore three high-consequence legal situations in which neurally-decoded speech could have implications:Testimony, where decoded speech is used as evidence;Consent and Capacity, where it may be used as a means of agency and participation such as consent to medical treatment; andHarm, where such communications may be networked or may cause harm to others. We then illustrate how design choices might impact the social and legal acceptability of these technologies. (shrink)

Epistemologists can be divided into two camps: those who think that nothing short of certainty or (subjective) probability 1 can warrant assertion and those who disagree with this claim. This paper addressed this issue by inquiring into the problem of setting the probability threshold required for assertion in such a way that that the social epistemic good is maximized, where the latter is taken to be the veritistic value in the sense of Goldman (Knowledge in a social world, 1999). We (...) provide a Bayesian model of a test case involving a community of inquirers in a social network engaged in group deliberation regarding the truth or falsity of a proposition $p.$ p . Results obtained by means of computer simulation indicate that the certainty rule is optimal in the limit of inquiry and communication but that a lower threshold is preferable in less idealized cases.

Drawing on face-to-face and online ethnographic, survey and interview data with participants in distributed computing projects around the world, this book sheds light on the organizational and social structures of voluntary distributed computing projects, communities and teams, with close attention to questions of motivation in projects that offer little or no traditional forms of reward, either financially or in terms of participants' careers. With its focus on non-market, non-hierarchical cooperation, this book is a case study of networked individuals around the (...) world who are part of a new social production of information. (shrink)

I propose that a sociological and historical examination of nanotechnologists can contribute more to an understanding of nanotechnology than an ontological definition. Nanotechnology emerged from the convergent evolution of numerous "technical knowledge communities"-networks of tightly-interconnected people who operate between disciplines and individual research groups. I demonstrate this proposition by sketching the co-evolution of computational chemistry and computational nanotechnology. Computational chemistry arose in the 1950s but eventually segregated into an ab initio, basic research, physics-oriented flavor and an industry-oriented, molecular modeling and (...) visualization, biochemical flavor. Computational nanotechnology arose in the 1990s as a synthesis of these two subgroups, infused by people and practices from computational materials science, engineering, computer science, and elsewhere. I show that to understand the aims and outcomes of computational nanotechnology-and nanotechnology more generally-we need to understand relationships between different, but related, nano knowledge communities and their dependence on particular practices, artifacts, and theories.

Achieving meaningful usage of the Internet is more than attaining access: multiple social and technological insufficiencies must be overcome and continually readdressed. A wide variety of approaches have been undertaken to address these issues, both to enable individuals to cross the ‘digital divide’ and also to enhance community interactions. In this paper, we focus on one approach–grassroots networked communities. These are communities of locality that have developed their own computer network infrastructure with minimal external support. We analyse eight examples (...) from the UK and present survey results, identifying key characteristics and modes of operation. We argue that such initiatives may offer a viable method of overcoming multiple digital insufficiencies and ensure sustainable and meaningful ICT usage. Further research has commenced to analyse how the presence of social software and near-ubiquitous computer network access affects the sharing and storage of information within communities of locality.

Functional near-infrared spectroscopy has attracted increasing attention in the field of brain–computer interfaces owing to their advantages such as non-invasiveness, user safety, affordability, and portability. However, fNIRS signals are highly subject-specific and have low test-retest reliability. Therefore, individual calibration sessions need to be employed before each use of fNIRS-based BCI to achieve a sufficiently high performance for practical BCI applications. In this study, we propose a novel deep convolutional neural network -based approach for implementing a subject-independent fNIRS-based BCI. A (...) total of 18 participants performed the fNIRS-based BCI experiments, where the main goal of the experiments was to distinguish a mental arithmetic task from an idle state task. Leave-one-subject-out cross-validation was employed to evaluate the average classification accuracy of the proposed subject-independent fNIRS-based BCI. As a result, the average classification accuracy of the proposed method was reported to be 71.20 ± 8.74%, which was higher than the threshold accuracy for effective BCI communication as well as that obtained using conventional shrinkage linear discriminant analysis. To achieve a classification accuracy comparable to that of the proposed subject-independent fNIRS-based BCI, 24 training trials were necessary for the traditional subject-dependent fNIRS-based BCI. It is expected that our CNN-based approach would reduce the necessity of long-term individual calibration sessions, thereby enhancing the practicality of fNIRS-based BCIs significantly. (shrink)

This article is devoted to the study of the specific features of the display of social networks and computer technologies in the late 70s of the XX – early 20s of the XXI century in the fantastic Star Wars universe created by American filmmaker D. Lucas. In this scientific work, the authors argue for the relevance and scientific novelty of the problem under consideration. The study examines the peculiarities of the influence of social networks and computer technologies in (...) modern conditions. The article provides a justification for the need to analyze the reflection of this issue in fantasy art as an auxiliary factor in the development of the prognostic function of science. This paper provides a reasoned explanation of the choice of the Star Wars universe as an object of research, taking into account its importance in the fantasy genre, as well as in order to refute stereotypes according to which Star Wars is a collection of entertainment materials in which there is completely no semantic load. The authors analyze the fundamental differences in the coverage of the studied problem in such genres of art as literature and cinema in the context of Star Wars. The article examines the features of the evolution of the display of cybernetic technologies and communication network platforms in the Star Wars universe in the mid‑1970s – early 2020s, as a reflection of the real development of scientific and technological progress, as well as an example of the impact of political, socio‑economic and moral factors on the use of online platforms and computer technology during the period under study. In this article, using the example of the Star Wars universe, the features of the transformation of the role of specialists in the field of high technology through the prism of the attitude of artists to them – more specifically, writers and cinematographers – are also considered. The article also examines the moral and ethical aspect of the use of computer technology and social networks, considered by artists who have made a significant contribution to the development of the fantastic epic of Star Wars.

This paper considers current personalized recommendation approaches based on computational social systems and then discusses their advantages and application environments. The most widely used recommendation algorithm, personalized advice based on collaborative filtering, is selected as the primary research focus. Some improvements in its application performance are analyzed. First, for the calculation of user similarity, the introduction of computational social system attributes can help to determine users’ neighbors more accurately. Second, computational social system strategies can be adopted to penalize popular items. (...) Third, the network community, identity, and trust can be combined as there is a close relationship. Therefore, this paper proposes a new method that uses a computational social system, including a trust model based on community relationships, to improve the user similarity calculation accuracy to enhance personalized recommendation. Finally, the improved algorithm in this paper is tested on the online reading website dataset. The experimental results show that the enhanced collaborative filtering algorithm performs better than the traditional algorithm. (shrink)

Increasingly, biologists are using computers to model and to create biological representations. However, the exponential growth in available biological dataposes a challenge for experimental and theoretical researchers in both Biology and in Computer Science. In short, when even the simple retrieval of relevant biological information for a researcher becomes a complex task — its analysis and synthesis with other biological information will become even more daunting and unlikely. In this context, specially organized ‘structures of representation’ are needed for the (...) efficient interpretation of experimentally generated data. The “semantic Web” is a recent trend in networking techniques that we will examine here as a possible strategy for the computation of biological data — one that may allow us to take into account both the semiotic dimensions of biological processes, as well as their dynamic organization into stable and systemic levels. Thereupon, we propose that a semantic network for biology could benefit from principles rooted in such previous representation efforts as computer-generated ‘landscapes’ and ‘physical attractors’ — and that such principles could, in turn, then be better integrated into biological research through the development of a more semiotically informed user / computer interface design.

The paper presents and defends a Bayesian theory of trust in social networks. In the first part of the paper, we provide justifications for the basic assumptions behind the model, and we give reasons for thinking that the model has plausible consequences for certain kinds of communication. In the second part of the paper we investigate the phenomenon of overconfidence. Many psychological studies have found that people think they are more reliable than they actually are. Using a simulation environment (...) that has been developed in order to make our model computationally tractable we show that in our model inquirers are indeed sometimes better off from an epistemic perspective overestimating the reliability of their own inquiries. We also show, by contrast, that people are rarely better off overestimating the reliability of others. On the basis of these observations we formulate a novel hypothesis about the value of overconfidence. (shrink)

Thousands of youth suffering from acquired brain injury or other early-life neurological disease live, mature, and learn with only limited communication and interaction with their world. Such cognitively capable children are ideal candidates for brain-computer interfaces. While BCI systems are rapidly evolving, a fundamental gap exists between technological innovators and the patients and families who stand to benefit. Forays into translating BCI systems to children in recent years have revealed that kids can learn to operate simple BCI with (...) proficiency akin to adults. BCI could bring significant boons to the lives of many children with severe physical impairment, supporting their complex physical and social needs. However, children have been neglected in BCI research and a collaborative BCI research community is required to unite and push pediatric BCI development forward. To this end, the pediatric BCI Canada collaborative network was formed, under a unified goal to cooperatively drive forward pediatric BCI innovation and impact. This article reflects on the topics and discussions raised in the foundational BCI-CAN meeting held in Toronto, ON, Canada in November 2019 and suggests the next steps required to see BCI impact the lives of children with severe neurological disease and their families.

Félix Guattari's theoretical and practical interests in cinema culminated in the film project A Love of UIQ. While critics have concentrated on the sci-fi screenplay's elements of minor cinema, its themes of mass media, emerging computer technologies and informatic-communication networks particularly express Guattari's concept of post-media. The screenplay is an aesthetic meditation on the potentialities of post-media, a concept that anticipates the practical and theoretical issues surrounding the age of the Internet. A Love of UIQ voices Guattari's ambivalence (...) towards the liberatory possibilities of network technologies that are at constant risk of capitalist recapture. (shrink)

This book bridges the divide between the fields of power systems engineering and computer communication through the new field of power system information theory. Written by an expert with vast experience in the field, this book explores the smart grid from generation to consumption, both as it is planned today and how it will evolve tomorrow. The book focuses upon what differentiates the smart grid from the "traditional" power grid as it has been known for the last century. (...) Furthermore, the author provides the reader with a fundamental understanding of both power systems and communication networking. It shows the complexity and operational requirements of the evolving power grid, the so-called "smart grid," to the communication networking engineer; and similarly, it shows the complexity and operational requirements for communications to the power systems engineer. The book is divided into three parts. Part One discusses the basic operation of the electric power grid, covering fundamental knowledge that is assumed in Parts Two and Three. Part Two introduces communications and networking, which are critical enablers for the smart grid. It also considers how communication and networking will evolve as technology develops. This lays the foundation for Part Three, which utilizes communication within the power grid. Part Three draws heavily upon both the embedded intelligence within the power grid and current research, anticipating how and where computational intelligence will be implemented within the smart grid. Each part is divided into chapters and each chapter has a set of questions useful for exercising the readers' understanding of the material in that chapter. Key Features: Bridges the gap between power systems and communications experts Addresses the smart grid from generation to consumption, both as it is planned today and how it will likely evolve tomorrow Explores the smart grid from the perspective of traditional power systems as well as from communications Discusses power systems, communications, and machine learning that all define the smart grid It introduces the new field of power system information theory.

The paper takes a Critical Discourse Analysis angle and joins Social Media Studies and Religious Studies perspectives of Computer Mediated Communication material to examine such strategies of online interpersonal communication as may foster civic solidarity on social networks sites over local incidents with national and international media coverage. Computer mediated discourse is often underpinned by ideological antagonism especially when tackling social, political, cultural and even religious issues. Our topic choice was occasioned by an infelicitous episode – (...) a fire in a local venue hosting a rock concert that resulted in a high number of casualties and fatalities. The tragic episode triggered some polarized and highly opinionated positioning in the social media, both independent of and/or in retaliation to media sourced accounts and personal posts. We analyzed qualitatively authentic CMC material as well as edited media inputs in order to establish if and how the networked, yet generationally diverse, public achieve symbolic solidarity through reactive and correlated digi-participation where sociocultural identities become tangent to such ecclesiastic issues as became salient and were up-cycled in the local political conjecture.

Societal structures and memory organization models share network‐like features, offering insights into how information spreads and shapes collective memories. In this study, we manipulated the structure of lab‐created community networks during a computer‐mediated recall task using the Deese–Roediger–McDermott paradigm to test the spreading activation theory of true and false memory formation. We hypothesized that social network structure, whether clustered or not, would influence memory accuracy. Our results showed that clustered networks reinforced true memories by promoting mnemonic convergence, while non‐clustered (...) networks led to more false memories by increasing widespread cross‐activation. These findings highlight how social network topology impacts memory dynamics and collective knowledge evolution. (shrink)

Public health care interventions—regarding vaccination, obesity, and HIV, for example—standardly take the form of information dissemination across a community. But information networks can vary importantly between different ethnic communities, as can levels of trust in information from different sources. We use data from the Greater Pittsburgh Random Household Health Survey to construct models of information networks for White and Black communities--models which reflect the degree of information contact between individuals, with degrees of trust in information from various sources correlated with (...) positions in that social network. With simple assumptions regarding belief change and social reinforcement, we use those modeled networks to build dynamic agent-based models of how information can be expected to flow and how beliefs can be expected to change across each community. With contrasting information from governmental and religious sources, the results show importantly different dynamic patterns of belief polarization within the two communities. (shrink)

The aim of this paper is to explore the development of brain-computer interfacing and cloudminds as possible future scenarios. I describe potential applications such as selling unused brain processing cycles and the blockchaining of personality functions. The possibility of ubiquitous brain-computer interfaces that are continuously connected to the Internet suggests interesting options for our future selves. Questions about what it is to be human; the nature of our current existence and interaction with reality; and how things might be (...) different could become more prominent. I examine speculative future scenarios such as digital selves and cloudmind collaborations. Applications could be adopted in tiers of advancing complexity and risk; starting with health tracking; followed by information seeking and entertainment; and finally; self-actualization. By linking brains to the Internet; BCIs could allow individuals to be more highly connectable not just to communications networks but also to other minds; and thus could enable participation in new kinds of collective applications such as a cloudmind. A cloudmind is the concept of multiple individual minds joined together to pursue a collaborative goal such as problem solving; idea generation; creative expression; or entertainment. The prospect of cloudminds raises questions about individual versus collective personhood. Some of the necessary conditions for individuals to feel comfortable in joining a cloudmind include privacy; security; reversibility; and retention of personal identity. Blockchain technology might be employed to orchestrate the security; automation; coordination; and credit-assignation requirements of cloudmind collaborations. (shrink)

The title of the article was inspired by the novel by John Steinbeck “Of Mice and Men” (1937) and the poem by Robet Burns about the deception of human plans. Even the best of them often lead astray, or their far-reaching negative effects are revealed.

PurposeThe purpose of this paper is to describe some of the methodological challenges of investigating privacy and ubiquitous computing in the home, particularly among the healthy elderly.Design/methodology/approachThe paper is based on focus groups with 60 senior citizens either living independently or in an assisted living facility. Prototypes of home‐based ubiquitous computing devices were created and deployed in a home‐like living lab setting; elders were brought to the lab to interact with the prototypes, then brought together in focus groups to discuss (...) their insights and concerns.FindingsInitial analyses suggest that extant metaphors of privacy may be inadequate for understanding pervasive computing in the home. Concepts of data, affective concerns, and the creation of appropriate prototypes for eliciting privacy are considered. Considerations for future studies of the elderly and privacy are made.Research limitations/implicationsThe homogeneity of the study population in terms of socioeconomic status, location, and community networks suggests that the study needs to be repeated with wider populations.Originality/valueAlthough a number of projects and studies have examined the usability of home‐based ubiquitous computing and design for aging, there has been little integration of privacy and ethical concerns into general research discourse.

Social network structure has been argued to shape the structure of languages, as well as affect the spread of innovations and the formation of conventions in the community. Specifically, theoretical and computational models of language change predict that sparsely connected communities develop more systematic languages, while tightly knit communities can maintain high levels of linguistic complexity and variability. However, the role of social network structure in the cultural evolution of languages has never been tested experimentally. Here, we present results from (...) a behavioral group communication study, in which we examined the formation of new languages created in the lab by micro‐societies that varied in their network structure. We contrasted three types of social networks: fully connected, small‐world, and scale‐free. We examined the artificial languages created by these different networks with respect to their linguistic structure, communicative success, stability, and convergence. Results did not reveal any effect of network structure for any measure, with all languages becoming similarly more systematic, more accurate, more stable, and more shared over time. At the same time, small‐world networks showed the greatest variation in their convergence, stabilization, and emerging structure patterns, indicating that network structure can influence the community's susceptibility to random linguistic changes (i.e., drift).

What structure of scientific communication and cooperation, between what kinds of investigators, is best positioned to lead us to the truth? Against an outline of standard philosophical characteristics and a recent turn to social epistemology, this paper surveys highlights within two strands of computational philosophy of science that attempt to work toward an answer to this question. Both strands emerge from abstract rational choice theory and the analytic tradition in philosophy of science rather than postmodern sociology of science. The (...) first strand of computational research models the effect of communicative networks within groups, with conclusions regarding the potential benefit of limited communication. The second strand models the potential benefits of cognitive diversity within groups. Examples from each strand of research are used in analyzing what makes modeling of this sort both promising and distinctly philosophical, but are also used to emphasize possibilities for failure and inherent limitations as well.

The paper discusses ubiquitous computing and the conception of the self, especially the question how the self should be understood in the environment pervaded by ubiquitous computing, and how ubiquitous computing makes possible direct empathy where each person or self connected through the network has direct access to others’ thoughts and feelings. Starting from a conception of self, which is essentially distributed, composite and constituted through information, the paper argues that when a number of selves are connected to one another (...) in the ubiquitous computing network, a possibility opens up where the selves can directly communicate with one another. This has a potential finally to solve the problem of other minds, and in fact any philosophical conundrum based on the supposed distinction between self and the world. When selves have direct access to others’ thoughts and feelings, they know the content of others’ mental states directly without having to make inferences or employing some other indirect methods. As they are interconnected through the ubiquitous network, and as they are essentially constituted through information, the selves then are spread out across the network. What this implies is that any boundary between a self and another is not as hard and fast as hitherto may have been understood. Toward the end, the paper also discusses how freedom and autonomy are still possible in this ubiquitously networked world. (shrink)

In recent years, the "science of science" has combined computational methods with novel data sources in order to understand the dynamics of research communities. As the name suggests, science of science is primarily focused on science and technology, with less attention to the humanities. However, many of the questions investigated by science of science are also relevant to academic philosophy: To what extent can the discipline be divided into subfields with different methods and topics? How are prestige and credit distributed (...) across the discipline? And how do these factors interact with other factors, such as gender, to shape job market outcomes? In this paper, we provide some empirically-informed answers to these questions by applying computational methods to job market data for Anglophone academic philosophy. We find, first, evidence that is consistent with the analytic-continental divide, but is also consistent with other, more complex ways of organizing academic philosophy into distinct intellectual traditions; second, a clear prestige hierarchy, dividing PhD programs into two distinct prestige categories; and third, evidence that gender, prestige, and country have notable effects on academic job market outcomes for recent philosophy PhDs.

Active participation closely associates with the sustainable operation of co-creation communities. Different from recent studies on the promotion of sustainable operation by identifying the internal and external motivations of user participation, this paper aims to analyze the mechanism regarding how different motivations affect the decision of user participation from group-level perspective. To better understand the mechanism, internal and external motivations are, respectively, captured by return-cost analysis and user interactive network. Afterwards, a network evolutionary game model was formulated to analyze the (...) dynamic strategy selection of all users. In addition, the stable equilibrium and evolutionary path of strategies are analyzed through computational experiments. Results indicate the following: Rewards have an influence on the promotion of active participation. However, with the continued growth of rewards, this promotion does not make sense sustainably. The promotional effect of information noise on the selection of active participation can be found when passive participation is the dominant strategy. However, the inhibitory effect can be seen in populations that mainly adopt active participation. The scale-free feature of user interactive network inhibits the selection of active participation when active participation is the dominant strategy in populations. Results found here is beneficial for managers to implement the specified policies and thus to achieve the sustainability of co-creation community. (shrink)

This article is devoted to the analysis of the characteristic features of the process of displaying virtual network platforms and cybernetic technologies in the early 1970s — early 2020s in the fantastic universe (literary and cinematic) created by S. King, one of the leading American science fiction writers of our time. In this study, the authors provide a justification for the relevance and scientific novelty of the problem under study. This paper analyzes the specific features of the impact of electronic (...) communication communities and computer technologies on modern society. This article provides an argument for the need to comprehend the coverage of this social problem in fantastic art — specifically in literature and cinematography — as one of the additional aspects of the progress of the predictive function of science. This study provides a reasoned explanation of the definition of the fantastic literary and cinematic universe of S. King as an object of research, taking into account its priority position in the fantasy genre as a whole. This problem was chosen by the authors for analysis in order to reasonably refute stereotypes, according to which the works of S. King and the film adaptations created on their basis are a complex of mass culture materials of an entertainment nature that do not have any semantic significance. At the same time, the authors explore the cardinal differences in the coverage of the studied problem in the original literary works of S. King and their film adaptations. This approach, among other things, allowed the authors to identify the reasons for the negative attitude of the writer to the embodiment of his books on the cinema screen. In this work, the specifics of the process of transformation of the display of social networks and high technologies in the fantastic universe of S. King during the 1970s and early 2020s are comprehended in the context of the author’s reaction to objective changes in scientific and technological progress and ideas about it in public opinion, as well as the growth of their importance in socio-economic, spiritual and the political spheres of life of the human community. In this study, using the example of the fantastic universe of S. King, the characteristic features of the evolution of the position of experts in the field of computer technology over the past five decades in the context of their perception in literature and cinema are also analyzed. The work also examines the moral criteria for the use of social networks and cybernetic technologies in public life and their impact on the development of modern family relations in the perception of S. King, one of the subjects of the formation of public relations in Western society. (shrink)

Community detection is a major issue in network analysis.

The limited recognition and reception of Gardin's innovative computer application to the (...) humanities are addressed through two factors, in addition to the effects of historiography and bibliographies on the recording, discoverability, and reuse of scientific productions: (1) funding policies, evidenced by the transfer of research effort on graph applications from temporary interdisciplinary spaces to disciplinary organizations related to the then-emerging field of computer science; and (2) the erratic careers of algorithms, in which efficiency, flaws, corrections, and authors’ status, were determining factors.

This study examines the Italian Twitter landscape during the 2015 Syrian and 2022 Ukrainian refugee crises, with a focus on the evolution of anti-refugee discourse. Through the analysis of 400,000 tweets, we sought to identify attitudinal communities, track changes in user positions, and evaluate the trending potential of the communities. Our findings indicate a shift in opinion leaders within the anti-refugee community from 2015, alongside a persistent ability to influence public discourse. Additionally, while the pro-Ukrainian refugee community has grown, incorporating (...) previously neutral users, it remains loosely connected. Finally, the shifts in attitudes of Italian populist leaders regarding Syrian and Ukrainian refugees are interpreted in light of the changes in user attitudes as observed in the communication networks. This research highlights the importance of computational communication methods for investigating fringe groups absent from mainstream discourse, and underscores the necessity of content moderation and proactive digital activism to counter anti-refugee sentiment online.

Andfinally, I discuss a few of the political andepistemic constraints on participation (...) in thecomputer-mediated public sphere that threaten thecosmopolitan ideal.``Nature should be thanked for fostering socialincompatibility, enviously competitive vanity, andinsatiable desires for possessions and even power.Without these desires, all man''s excellent naturalcapacities would never be roused to develop.''''

Ironically, however, as Habermas andothers have realized, Kant''s carefully developedvision for `perpetual peace'' among nations and `worldcitizenship'' is now murky even as the electronicallymediated infrastructure of that matrix is rapidlydeveloping. Globalization as a process has intensifiedto the point where a new social, political, andeconomic condition has taken hold in the global arena.Recently this condition has been termed ``globality'''' –a term denoting a networked world characterized byspeed, mobility, risk, insecurity, andflexibility. And a debate is forming around thequestion of whether we are still in late modernity andexperiencing the culmination of modernity''s inherentlyglobalizing tendency or instead we have entered thenetworked age, in which the tension between collectiveand transformative identities and the networking logicof dominant institutions and organizations heralds theend of civil society. Inthis paper assume the latter but wish to explorefurther the political and epistemic constraints onparticipation in the computer-mediated public sphere.These constraints seem certain to impact the viabilityof a cosmopolitan public sphere. In the first sectionI shall discuss James Bohman''s definition of theglobal and cosmopolitan spheres and howcomputer-mediated communication (hereafter CMC) mightimpact the development of those spheres. In the secondsection, I question the commitment to purely rationalmodels of social cooperation when theorizing a globalpublic sphere. I explore recently proposed alternativeways of thinking about this issue in section three.And finally, I discuss a few of the political andepistemic constraints on participation in thecomputer-mediated public sphere that threaten thecosmopolitan ideal.

Digital media presents an array of interesting challenges adapting new modes of collaborative, online communication to traditional writing and literary practices at the practical and theoretical levels. For centuries, popular concepts of the modern author, regardless of genre, have emphasized writing as a solo exercise in human communication, while the act of reading remains associated with solitude and individual privacy. "The Community and the Algorithm: A Digital Interactive Poetics" explores important cultural changes in these relationships thanks to the (...) rapid development of digital internet technologies allowing near-instantaneous, synchronous, multimedia interaction across the globe. The radical shift in how we author and consume media as an online, electronic transmission effectively resituates the writing process across the liberal arts as less a solitary act of individual enquiry and reflection, and more an ongoing, collaborative process of creative interaction within a multimedia environment or network. Contributions in this anthology demonstrate a robust history and equally diverse contemporary approach to multimedia interaction for literary and artistic ends. Central to all media formats, computation is explored throughout this volume to critically examine how algorithmic procedures in writing help bring forward many key concepts to building creative communities in a digital environment. Each chapter in this book accordingly introduces readers to various new collaborative experiments using a broad range of different digital media formats, including VR, Natural Language Generation (NLG), and metagaming tools. This book will appeal broadly to students, instructors, and independent artists working in the digital arts, while its emphasis on social interactivity will interest theorists and teachers working in theatre, social media, and cyberpsychology. Its secondary focus on computation and media programming as a site of artistic experimentation will also interest programmers and web designers at various professional levels. (shrink)

In normative ethical theory, computer ethics belongs to the area of applied ethics dealing with practical and everyday moral problems arising from the use of computers and computer networks in the information society. Modern scholarship usually approves deontological and utilitarian ethics as appropriate to computer ethics, while classical theories of ethics, such as virtue ethics, are usually neglected as anachronistic and unsuitable to the information era and ICT industry. During past decades, an Aristotelian form of virtue ethics (...) has been revived in modern philosophical enquiries with serious attempts for application to computer ethics and cyberethics. In this paper, the author argues that current trends and behaviours in online communication require an ethics of self-care found in Plotinus’ self-centred virtue ethics theory. The paper supports the position that Plotinus’ virtue ethics of intellectual autonomy and self-determination is relevant to cyberethics discussions involved in computer education and online communication.

Towards the end of the 1960s—a period of intense creative, technological and political changes—the Argentinian art critic and entrepreneur Jorge Glusberg founded the CAyC in Buenos Aires. CAyC was an interdisciplinary experimental project that explored the relationship between art, technology and society. It sought to articulate a network of discussions and productions by a new style of Latin American artist, deeply influenced by science, technology and society. Glusberg defined such practice as Systems Art, which appeared in three ways, namely as (...) a system of collective representation; a system of meaning that defied formal categories; and a system of relationships and processes for social inquiry. In doing so, the artist became a researcher who reflected on their social context and the latter’s processes of production. This paper will discuss CAyC’s pioneering work and its global influence through three main initiatives: its exhibitions Art and Cybernetics, Systems Art in Latin America and the International Open Encounters on Video. These events were driven by the revolutionary artistic and experimental promotion of the distinctive ways in which Latin American artists were using technology to respond to local issues at a time when computer systems and cybernetic models for management and organizational practices were being introduced across the region.

The emerging area of network biology is seeking to provide insights into organizational principles of life. However, despite significant collaborative efforts, there is still typically a weak link between biological and computational scientists and a lack of understanding of the research issues across the disciplines. This results in the use of simple computational techniques of limited potential that are incapable of explaining these complex data. Hence, the danger is that the community might begin to view the topological properties of network (...) data as mere statistics, rather than rich sources of biological information. A further danger is that such views might result in the imposition of scientific doctrines, such as scale-free-centric (on the modeling side) and genome-centric (on the biological side) opinions onto this area. Here, we take a graph-theoretic perspective on protein-protein interaction networks and present a high-level overview of the area, commenting on possible challenges ahead. (shrink)

All epistemic agents physically consist of parts that must somehow comprise an integrated cognitive self. Biological individuals consist of subunits (organs, cells, molecular networks) that are themselves complex and competent in their own context. How do coherent biological Individuals result from the activity of smaller sub-agents? To understand the evolution and function of metazoan bodies and minds, it is essential to conceptually explore the origin of multicellularity and the scaling of the basal cognition of individual cells into a coherent larger (...) organism. In this paper I synthesize ideas in cognitive science, evolutionary biology, and developmental physiology toward a hypothesis about the origin of Individuality: “Scale-Free Cognition”. I propose a fundamental definition of an Individual based on the ability to pursue goals at an appropriate level of scale and organization, and suggest a formalism for defining and comparing the cognitive capacities of highly diverse types of agents. Any Self is demarcated by a computational surface – the spatio-temporal boundary of events that it can measure, model, and try to affect. This surface sets a functional boundary - a cognitive “light cone” which defines the scale and limits of its cognition. I hypothesize that higher-level goal-directed activity and agency, resulting in larger cognitive boundaries, evolve from the primal homeostatic drive of living things to reduce stress – the difference between current conditions and life-optimal conditions. The mechanisms of developmental bioelectricity - the ability of all cells to form electrical networks that process information - suggests a plausible set of gradual evolutionary steps that naturally lead from physiological homeostasis in single cells to memory, prediction, and ultimately complex cognitive agents, via scale-up of the drive of infotaxis. Recent data on the molecular mechanisms of pre-neural bioelectricity suggest a model of how increasingly sophisticated cognitive functions emerge smoothly from cell-cell communication used to guide embryogenesis and regeneration. This set of hypotheses provides a novel perspective on numerous phenomena, such as cancer, and makes several unique, testable predictions for interdisciplinary research that have implications not only for evolutionary developmental biology but also for biomedicine and perhaps artificial intelligence and exobiology.

This paper examines flexibility in ad hoc networks and suggests that, even with cross-layer design as a mechanism to improve adaptation, a fundamental limitation exists in the ability of a single optimization function, defined a priori, to adapt the network to meet all quality-of-service requirements. Thus, code implementing multiple algorithms will have to be positioned within the network. Active networking and programmable networking enable unprecedented autonomy and flexibility for ad hoc communication networks. However, in order to best leverage the (...) results of active and programmable networking, metrics that indicate the nature and location of required flexibility need to be developed. The primary contribution of this paper is to propose a metric that couples network topological rate of change with the ability of a generic service to move itself to an optimal location in concert with the changing network. This metric points to a fundamental tradeoff among adaptation (changing service location), performance (sophistication or estimated minimum code size of the service), and the network’s ability to tune itself to a changing ad hoc network topology.

La scalabilità è una proprietà desiderabile di sistemi informatici associata a metriche di performance. Più precisamente, un sistema è definito scalabile quando riesce a gestire, senza calo di prestazioni, un numero crescente di elementi, processi, quantità di lavoro e/o quando può essere espanso a piacimento. Progettare un sistema scalabile garantisce un’ottimizzazione dei costi e delle prestazioni, e della produttività di un’azienda. Questi scopi sono stati perseguiti, dagli anni Ottanta, attraverso numerosi studi sulla scalabilità, che sono stati sviluppati in un ambito (...) esclusivamente tecnologico. Tuttavia, negli ultimi anni è sorto il bisogno di estendere la tradizionale prospettiva tecnologica della scalabilità perché troppo limitata considerata al di fuori delle organizzazioni e applicata alle situazioni di uso quotidiano delle nuove tecnologie. Per esempio, le rubriche dei telefonini sono tecnicamente scalabili: grazie alla funzione di ricerca, essi offrono un accesso immediato alle informazioni indipendentemente dal numero dei contatti memorizzati. Inoltre, il supporto di memorie digitali esterne molto capienti permette di inserire un numero pressoché illimitato di contatti. Le versioni più avanzate delle rubriche degli smartphones sono integrate anche con i social network come Facebook. Dal punto di vista cognitivo, negli utenti si crea un’illusione di essere in grado di gestire efficacemente reti sociali sempre più estese e ricche di contenuti. In realtà, vari studi hanno dimostrato che esistono dei limiti alla gestione di relazioni sociali rilevanti, quali il famoso numero di Dunbar. Pertanto, la prospettiva tecnologica sulla scalabilità è limitata nel senso che essa riesce a descrivere solo la performance di un sistema informatico, ma non ne spiega l’impatto su performance cognitiva e sociale. Un approccio alternativo potrebbe essere basato sul presupposto che la scalabilità è una proprietà importante non solo per computer e reti informatiche, ma anche per esseri umani e reti sociali. La comprensione della correlazione fra scalabilità tecnologica e umana, renderebbe possibile migliorare il design delle tecnologie per uso quotidiano. Per esempio, le rubriche dei telefonini, come anche i siti di social network, potrebbero ottimizzare l’accesso ai contenuti in base al significato delle relazioni sociali e della situazione nella quale sono considerate. Si può ipotizzare che la comprensione della scalabilità, sia umana sia tecnologica, possa permettere di migliorare la performance dell’azione individuale e/o collettiva. Socionics, un programma interdisciplinare di ricerca che integra sociologica e informatica, offre la possibilità di estendere la definizione di scalabilità anche ai sistemi sociali. Al contrario della prospettiva tradizionale della scalabilità, che è incentrata sull’aspetto quantitativo, Socionics pone al centro dell’analisi il problema da risolvere, che è analizzato sia dal punto di vista quantitativo sia da quello qualitativo . Grazie a Socionics, nell’articolo sono introdotti i concetti di scalabilità cognitiva e scalabilità sociale, che descrivono la capacità di gestire elegantemente a livello individuale o collettivo quantità crescenti di lavoro, e/o adattarsi alla loro complessità crescente. Il processo di valutazione della scalabilità cognitiva e sociale di un problema si compone di tre fasi: la prima riguarda la definizione del contesto dell’attività a cui il problema è associato. Questo richiede di specificare gli attori coinvolti, le risorse disponibili e i compiti che essi stanno svolgendo, individualmente o in gruppo. La seconda fase si propone di identificare i bisogni legati al contesto, che servono a capire in che misura il sistema è riuscito a soddisfare il bisogno, ovvero a misurare la performance. Nella terza e ultima fase si considera la funzione delle ICT nella risoluzione del problema, al fine di capire se le ICT abbiano alleviato, accentuato o rimosso eventuali limitazioni cognitive e/o sociali. Lo stesso problema è scalabile da un punto di vista cognitivo e/o sociale se esso è risolto in modo efficace al variare dei suoi elementi quantitativi e qualitativi. Per una prima valutazione dell’approccio, è discusso il problema della coordinazione sociale tramite telefonini, che non è ridotto semplicemente al numero di persone che i telefonini riescono a mobilizzare, ma anche alla qualità e impatto della loro performance. In conclusione, i concetti di scalabilità cognitiva e sociale offrono l’opportunità di informare la progettazione e favorire l’adozione di ICT grazie alla comprensione di come gli aspetti di scalabilità tecnologica influiscano sulla performance individuale e collettiva, e viceversa.Scalability has been for long time presented as a desirable property of a networked computer system associated to measure of its performance. As information and communication technologies become ubiquitous, a need of describing scalability also from a human perspective has emerged. Indeed, technical scalability only describes the performance of a computer system, but it does not explain anything about its impact on cognitive and social performance. Without acknowledging that technical scalability does not imply human scalability, there is the risk of not realizing the full potential of ICT in the everyday life. By adopting the Socionics approach, we extend the technical view of scalability with two additional concepts, namely cognitive and social scalability. These concepts describe the capacity to process individually or collectively growing volumes of work gracefully, and/or to adjust to their increasing complexity. The notion of social scalability is then evaluated in the activity-context of social coordination through mobile devices. We conclude that by improving our understanding of scalability issues, we may positively inform the design and use of ICT not only from the viewpoint of technical performance, but also for that of individual and collective performance.

This article synthesizes research presented in several models of unethical behavior to develop propositions about the factors that facilitate and mitigate deception in online business communications. The work expands the social network perspective to incorporate the medium of communication as a significant influence on deception. We go beyond existing models by developing seven propositions that identify how social network and issue moral intensity characteristics influence the probability of deception in online business communication in comparison to traditional communication (...) channels. Remedies to detect and discourage deception in online business networks are also offered, as well as limitations and future research directions. (shrink)

Computer and communication technologies created new modes of creating and sharing arts. In this paper, we apply ‘diffusion of innovation’ theory to investigate how artistic content travels in an online social network site called deviantArt, a site designed for sharing user-generated artworks. We first define what innovation corresponds to in such a context, and then discuss how it can be measured with the help of network, image and text analysis methods. We propose to use user-shared resources as relatively (...) easy targets of tracking innovation. (shrink)
