The self-visitation paradox is one paradox of time travel. As Ted Sider puts it, “Suppose I travel back in time and stand in a room with my sitting 10-year-old self. I seem to be both sitting and standing, but how can that be?” (2001, 101). So as not to beg any questions, let us label what is sitting B and what is standing C. The worry is about how B can be C in light of the looming contradiction (...) that this one person would be sitting and standing. Sider’s own approach is perdurantist, and holds that B is not C. My concern, though, is with solutions offered by, or on behalf of, endurantists–more 1 specifically, with solutions holding that B is C. The endurantist answer I shall criticize is a relativizer position maintaining that the sitting and the standing need to be relativized to the personal time or proper time of the time traveler. This manner of solution has been offered by Paul Horwich (1975, 433-435 ; 1987, 114-115) and also by Simon Keller and Michael Nelson (2001, 344). I will show that such a view has a linguistically suspect element and that there are three further reasons why relativizing only in this way falls short of solving the paradox. This will be enough to squash the relativizer position because it will not be clear how additional relativization could help, and furthermore any additional relativization would only make the linguistic matter worse. I will also present some considerations in favor of a non-contradiction endurantist alternative; this view eliminates the need for any relativization by denying that sitting and standing are contradictory properties.

Artificial Intelligence, in press. Abstract: For some time we have been developing, and have had significant practical success with, a time-sensitive, contradiction-tolerant logical reasoning engine called the active logic machine (ALMA). The current paper details a semantics for a general version of the underlying logical formalism, active logic. Central to active logic are special rules controlling the inheritance of beliefs in general (and of beliefs about the current time in particular), very tight controls on what can be (...) derived from direct contradictions (P &￢P), and mechanisms allowing an agent to represent and reason about its own beliefs and past reasoning. Furthermore, inspired by the notion that until an agent notices that a set of beliefs is contradictory, that set seems consistent (and the agent therefore reasons with it as if it were consistent), we introduce an “apperception function” that represents an agent’s limited awareness of its own beliefs, and serves to modify inconsistent belief sets so as to yield consistent sets. Using these ideas, we introduce a new definition of logical consequence in the context of active logic, as well as a new definition of soundness such that, when reasoning with consistent premises, all classically sound rules remain sound in our new sense. However, not everything that is classically sound remains sound in our sense, for by classical definitions, all rules with contradictory premises are vacuously sound, whereas in active logic not everything follows from a contradiction.

John Griffi n’s classic on racism, Black Like Me (1960), provides an interesting text with which to investigate the development of a dialogical self. Griffi n becomes a black man for only a short period of time, but during that time he develops a black social identity and sense of personal identity, that contrasts radically with his former white identity. When he looks into a mirror on several occasions he engages in a dialogue with himself, as both a (...) black and a white person. At fi rst these two identities are so different that there is no “sympathy” between them. But through his experience, he eventually overcomes the dichotomy of two opposing selves, and acquires a personal identity, neither white nor black, but just human. In this article, I trace the development of these dialogical selves and the emergence of this new human identity. Key words: identity, racism, self, black, white.. (shrink)

We investigate Kerr–Newman black holes in which a rotating charged ring-shaped singularity induces a region which contains closed timelike curves (CTCs). Contrary to popular belief, it turns out that the time orientation of the CTC is oppo- site to the direction in which the singularity or the ergosphere rotates. In this sense, CTCs “counter-rotate” against the rotating black hole. We have similar results for all spacetimes sufficiently familiar to us in which rotation induces CTCs. This motivates our conjecture that (...) perhaps this counter-rotation is not an accidental oddity particular to Kerr–Newman spacetimes, but instead there may be a general and intuitively comprehensible reason for this.

We address the general problem of determining the validity of boolean combinations of equalities and inequalities between real-valued expressions.

The performance records of cardiac surgeons have been disclosed publicly in several states in the USA, for example New York and Pennsylvania, since the early 1990s. In response to the growing interest in the quality of healthcare, such records have also begun to be disclosed in the UK, starting in 2004. Various studies seem to show that disclosure has, indeed, contributed to the improvement of the quality of healthcare.1 However, at the same time, disclosure does have its critics.2 In (...) this paper, I discuss what I call the ‘defensive medicine objection’ to the disclosure of performance data; that disclosure is not justified because it could cause surgeons to experience high levels of anxiety3, which might eventually lead to the practice of defensive medicine. Although this objection is often mentioned by ethicists and medical professionals4 it has never been carefully analysed or evaluated. The aim of this paper is to consider it in detail. I argue in favour of the objection; disclosure could, indeed, lead to the practice of defensive medicine if it is not conducted properly.5 This paper has the following structure. In Section 2 I discuss the anxiety that surgeons may experience regarding the disclosure of performance data. In Section 3 I introduce a traditional definition of defensive medicine. In Section 4 I argue that disclosure could encourage surgeons to perform a new form of defensive medicine, one that is not captured by the traditional definition. In Section 5 I undermine the claim that surgeons have no good reason to be anxious about disclosure. In Section 6 I consider a possible way of avoiding.. (shrink)

In [HKL00] (henceforth HKL), Hamm, Kamp and van Lambalgen declare ‘‘there is no opposition between formal and cognitive semantics,’’ notwithstanding the realist/mentalist divide. That divide separates two sides Jackendo¤ has (in [Jac96], following Chomsky) labeled E(xternalized)-semantics, relating language to a reality independent of speakers, and I(nternalized)-semantics, revolving around mental representations and thought. Although formal semanticists have (following David Lewis) traditionally leaned towards E-semantics, it is reasonable to apply formal methods also to I-semantics. This point is made clear in HKL via (...) two computational approaches to natural language semantics, Discourse Representation Theory (DRT, [KR93]) and the Event Calculus (EC) presented in [LH05]. In this short note, I wish to raise certain questions about EC that can be traced to the applicability of formal methods to E-semantics and I-semantics alike. These opposing orientations suggest di¤erent notions of time, event and representation. (shrink)

The Myopic Anthropic Principle: an attempt to show that the popular anthropic reasoning of our time — often taken to show that laws of nature are fine-tuned by a god for us — should be seen merely as an indication of fine-tuning by us. This preference for short-sightedness in this case is shown (shown?) to support the best-system account of scientific law.

Philosophers of mind tend to take it for granted that causal relations are part of the mind-independent, objective fabric of the physical world. In fact, their status has been hotly contested since Russell famously observed that the closest thing to causal relations in physics are timesymmetric dynamical laws relating global time slices of world-history. 1 These bear a distant relationship to the local, asymmetric relations that form the core of the folk notion of cause. Nancy Cartwright, in an influential (...) response, agreed about the absence of causal relations from physics, but argued that Russell’s position was not viable because agents choosing among potential actions need specifically causal information to distinguish effective from ineffective strategies for bringing about ends. 2 Causal beliefs play an ineliminable role in practical deliberation In recent years, there has been a great deal of progress in understanding the relationship between causal concepts and the dynamical laws that appear in advanced physics, together with a proliferation of new tools for representing and discovering causal structure.

In 2004 Orlando Florida was hit with an almost unprecedented series of storms and hurricanes. Within two months, Hurricanes Charley, Frances, and Jeanne hit, and Hurricane Ivan made a near miss. Billions of dollars of damage resulted from these disasters, and several dozen lives were lost. It is tempting, in the case of extreme events, to either regard them as having no need of interpretation (that is, as simply given, material events shared by everyone), or as a kind of rare (...) window on the workings of a community.1 In this paper I want to examine the public construction of the meaning of the hurricane in Orlando, particularly as represented in reports at the time in the major newspaper, the Orlando Sentinel. I am especially interested in placemaking, that is, the ways in which places gain or fail to gain meaning in times of stress. I will suggest that opportunities for place-making were lost in Orlando because of the frame the events around Hurricane Charley were given. Hurricane Frances, though, was treated differently in the Orlando press, and the discourse around the hurricanes of 2004 provides a contrast to the kind of rhetorical response that circulated during the disastrous hurricane season of 2005. In the case of some disasters, community is reinforced, and the skills of place-making are exercised. The reaction to Hurricane Charley in Orlando, on the other hand, tended not to reinforce community, and tended not to contribute to place-making. While it is extremely difficult to measure sense of place or sense of community quantitatively, it is possible to make sense out of the interpretive tools people have at their disposal in a disaster. What comes out of all this, I think, is something I want to call “place-making imagination”. This is analogous to the 1 concept of “moral imagination” in ethics (Johnson). Our moral options extend as far as our imagination will allow. A person might boil the moral universe down to polarized options – fight or flight, kill or be killed, choose A or B – when in fact a more cultivated and aware imagination may have afforded other options, perhaps better ones than either polarized one..

The Web initially emerged as an “antidote” to accumulated scientific knowledge, since it enables global representation and communication at a minimum cost. Its gigantic scale and interdependence allow us our ability to find relevant information and develop trustworthy contexts. It is time for science to compensate by providing an epistemological “antidote” to Web issues. Philosophy should be in the front line by forming the salient questions and analysis. We need a theory about Web being that will bridge philosophical thinking (...) and engineering. This article analyzes existence and spatiotemporality in the Web and how it transforms the traditional actualities. The resulting issues concern the self-determination of a being and the way in which the Web could be a free and open platform for innovation and participation. (shrink)

A new layer of complexity, constituted of networks of information token recurrence, has been identified in socio-technical systems such as the Wikipedia online community and the Zooniverse citizen science platform. The identification of this complexity reveals that our current understanding of the actual structure of those systems, and consequently the structure of the entire World Wide Web, is incomplete, which raises novel questions for data science research but also from the perspective of social epistemology. Here we establish the principled foundations (...) and practical advantages of analyzing information diffusion within and across Web systems with Transcendental Information Cascades, and outline resulting directions for future study in the area of socio-technical systems. We also suggest that Transcendental Information Cascades may be applicable to any kind of time-evolving system that can be observed using digital technologies, and that the structures found in such systems comprise properties common to all naturally occurring complex systems.

Social scientists are often interested in understanding how the dynamics of social systems are driven by the behavior of individuals that make up those systems. However, this process is hindered by the difficulty of experimentally studying how individual behavioral tendencies lead to collective social dynamics in large groups of people interacting over time. In this study, we investigate the role of social influence, a process well studied at the individual level, on the puzzling nature of success for cultural products (...) such as books, movies, and music. Using a “multiple‐worlds” experimental design, we are able to isolate the causal effect of an individual‐level mechanism on collective social outcomes. We employ this design in a Web‐based experiment in which 2,930 participants listened to, rated, and downloaded 48 songs by up‐and‐coming bands. Surprisingly, despite relatively large differences in the demographics, behavior, and preferences of participants, the experimental results at both the individual and collective levels were similar to those found in Salganik, Dodds, and Watts (2006). Further, by comparing results from two distinct pools of participants, we are able to gain new insights into the role of individual behavior on collective outcomes. We conclude with a discussion of the strengths and weaknesses of Web‐based experiments to address questions of collective social dynamics. (shrink)

KM (Knowledge Management) systems have recently been adopted within the realm of enterprise management. On the other hand, data mining technology is widely acknowledged within Information systems' R&D Divisions. Specially, acquisition of meaningful information from Web usage data has become one of the most exciting eras. In this paper, we employ a Web based KM system and propose a framework for applying Web Usage Mining technology to KM data. As it turns out, task duration varies according to different user operations (...) such as referencing a table-of-contents page, down-loading a target file, and writing to a bulletin board. This in turn makes it possible to easily predict the purpose of the user's task. By taking these observations into account, we segmented access log data manually. These results were compared with results abstained by applying the constant interval method. Next, we obtained a segmentation rule of Web access logs by applying a machine-learning algorithm to manually segmented access logs as training data. Then, the newly obtained segmentation rule was compared with other known methods including the time interval method by evaluating their segmentation results in terms of recall and precision rates and it was shown that our rule attained the best results in both measures. Furthermore, the segmented data were fed to an association rule miner and the obtained association rules were utilized to modify the Web structure. (shrink)

In order to improve the management of copyright in the Internet, known as Digital Rights Management, there is the need for a shared language for copyright representation. Current approaches are based on purely syntactic solutions, i.e. a grammar that defines a rights expression language. These languages are difficult to put into practise due to the lack of explicit semantics that facilitate its implementation. Moreover, they are simple from the legal point of view because they are intended just to model the (...) usage licenses granted by content providers to end-users. Thus, they ignore the copyright framework that lies behind and the whole value chain from creators to end-users. Our proposal is to use a semantic approach based on semantic web ontologies. We detail the development of a copyright ontology in order to put this approach into practice. It models the copyright core concepts for creation, rights and the basic kinds of actions that operate on content. Altogether, it allows building a copyright framework for the complete value chain. The set of actions operating on content are our smaller building blocks in order to cope with the complexity of copyright value chains and statements and, at the same time, guarantee a high level of interoperability and evolvability. The resulting copyright modelling framework is flexible and complete enough to model many copyright scenarios, not just those related to the economic exploitation of content. The ontology also includes moral rights, so it is possible to model this kind of situations as it is shown in the included example model for a withdrawal scenario. Finally, the ontology design and the selection of tools result in a straightforward implementation. Description Logic reasoners are used for license checking and retrieval. Rights are modelled as classes of actions, action patterns are modelled also as classes and the same is done for concrete actions. Then, to check if some right or license grants an action is reduced to check for class subsumption, which is a direct functionality of these reasoners. (shrink)

The current issue of the Zeitschrift für Medien- und Kulturforschung presents a discussion of social media's future. Geert Lovink and Stefan Heidenreich debate the sense and non-sense of network-critique in light of the internet's modified usage and perception, which is commonly labeled Web 2.0. Lovink is critical about the increasing tendency towards monopolization in Web 2.0. Users, he contends, become thrilled by walled gardens , which are presented to them by big companies. Independent of the question whether the need for (...) practical information and the prevalence of economical interests is understandable or not, Lovink is most of all concerned with artistic alternatives and an activist usage of the nets. According to him, it is time for developers, programmers, freaks and nerds of all nations to become conscious of and active against the dark sides of economical and political control over the internet. Heidenreich, on the other hand, is skeptical. In contrast to the project of network-critique, he pursues a rigorously medial approach, which presents itself as unimpressed by ethical or engaged observations of social media. In his view, the heroization of hackers and nerds is informed by Science Fiction and nostalgia, both of which miss Reality 2.0. Heidenreich asserts that the internet's new generation, which has grown up with the new media, is not particularly interested in network-critique, but uses the given internetservices in various ways. German In der aktuellen Ausgabe der Zeitschrift für Medien- und Kulturforschung wird über die Zukunft der Social Media gestritten. Geert Lovink und Stefan Heidenreich debattieren über den Sinn und Unsinn von Netzkritik angesichts einer veränderten Nutzung und Wahrnehmung des Internets, die sich hinter dem Schlagwort Web 2.0 verbirgt. Lovink sieht die zunehmende Tendenz zur Monopolisierung im Web 2.0 kritisch. Die Nutzer lassen sich von walled gardens begeistern, die Großunternehmen ihnen vorsetzen. Netzkritik solle sich daher nicht in der Frage erschöpfen, wie man Facebook und Twitter am besten nutzen kann, sondern sich mit echten Alternativen im Netz auseinandersetzen. Unabhängig davon, wie nachvollziehbar der Bedarf an praktischen Informationen und die Dominanz ökonomischer Interessen ist, geht es Lovink vor allem um künstlerische Alternativen und eine aktivistische Nutzung der Netze. Es sei an der Zeit, dass Entwickler, Programmierer, Freaks und Nerds aller Nationen sich die dunklen Seiten der ökonomisch-staatlichen Kontrolle des Internets bewusst machen und dagegen aktiv werden. Heidenreich ist dagegen skeptisch. Im Gegensatz zum Projekt der Netzkritik verfolgt er einen strikt medialen Ansatz, der sich gegenüber einer ethischen oder engagierten Beobachtung sozialer Medien kühl gibt. Die Heroisierung von Hackern und Nerds ist aus seiner Sicht von Science Fiction und Nostalgie geprägt, die an der Realität 2.0 vorbeigeht.

Visit the author's Web site at www.11PicsOfTime.com Time is a mystery that has perplexed humankind since time immemorial. Resolving this mystery is of significance not only to philosophers and physicists but is also a very practical concern. Our perception of time shapes our values and way of life; it also mediates the interaction between science and religion both of which rest fundamentally on assumptions about the nature of time. C K Raju begins with a critical exposition (...) of various time-beliefs, ranging from the earliest times through Augustine, Newton and Einstein to Stephen Hawking and current notions of chaos and time travel. He traces the role of organised religion in subverting time beliefs for its political ends. The book points out how this resulted in a facile dichotomy between 'linear' and 'cyclic' time, thereby inaugurating a confusion which, according to the author, has handicapped Western thought ever since, eventually influencing the content of science itself. Thus, this book daringly asserts that physical theory, traditionally regarded as amoral and objective, has depended on cultural beliefs about time. The author points out that time beliefs are again being manipulated today as the credibility of science is being exploited to promote a picture of time and, hence, a pattern of human behaviour which is convenient to the agenda of globalisation of culture. The linkages between modern theology and this 'brave new physics' are traced against the wider context of the so-called 'clash of civilisations', and the attempts to remake the world order. The conclusions point to the need to de-theologise time. The author challenges Einstein's understanding of relativity theory and suggests that a 'tilt in the arrow of time', or a small tendency towards cyclicity, will help repair the prevalent confusion about time. A 'tilt' also enables a physics that permits both memory and creativity, so that purpose and spontaneous growth of order are returned to human life. The book ends with a vision of Man as Creator, surprising God. Extensive research in physics, the history of science, comparative religions, and sociology lend weight to the important and challenging conclusions reached by the author. Written as a rejoinder to Stephen Hawking's A Brief History of Time, this book goes much further and, unlike any previous book, it gives a critical exposition of various world religions-Buddhism, Christianity, Hinduism, Islam, and Jainism-while exploring their intricate links, through time beliefs, to current physics on the one hand, and to global political and economic trends, on the other. This book will appeal to scholars and laypersons equally. It will fascinate anyone who reads it and will teach its readers to question the unquestionable. (shrink)

In order to shorten the time for users to query news on the Internet, this paper studies and designs a network news data extraction technology, which can obtain the main news information through the extraction of news text keywords. Firstly, the TF-IDF keyword extraction algorithm, TextRank keyword extraction algorithm, and LDA keyword extraction algorithm are analyzed to understand the keyword extraction process, and the TF-IDF algorithm is optimized by Zipf’s law. By introducing the idea of model fusion, five schemes (...) based on waterfall fusion and parallel combination fusion are designed, and the effects of the five schemes are verified by experiments. It is found that the designed extraction technology has a good effect on network news data extraction. News keyword extraction has a great application prospect, which can provide the basis for the research fields of news key phrases, news abstracts, and so on. (shrink)

Fundamental turns in biological understanding can be interpreted as replacements of deep models that organise the biological knowledge. Three deep models distinguished here are a holistic ladder model that sees all levels of nature being complete (from Aristotle to the 18th century), a modernist tree model that emphasises progress and evolution (from Enlightenment to the recent times), and a web model that evaluates diversity (since the 20th century). The turn from the tree model to the web model in biology includes (...) (1) a transfer from modern to postmodern approaches, (2) a shift of semiotic threshold to the border of life, and (3) building the semiotic models of living systems, i.e., the rise of biosemiotics.

Mind, it has recently been argued1, is a thoroughly temporal phenomenon: so temporal, indeed, as to defy description and analysis using the traditional computational tools of cognitive scientific understanding. The proper explanatory tools, so the suggestion goes, are instead the geometric constructs and differential equations of Dynamical Systems Theory. I consider various aspects of the putative temporal challenge to computational understanding, and show that the root problem turns on the presence of a certain kind of causal web: a web that (...) involves multiple components (both inner and outer) linked by chains of continuous and reciprocal causal influence. There is, however, no compelling route from such facts about causal and temporal complexity to the radical anti- computationalist conclusion. This is because, interactive complexities notwithstanding, the computational approach provides a kind of explanatory understanding that cannot (I suggest) be recreated using the alternative resources of pure Dynamical Systems Theory. In particular, it provides a means of mapping information flow onto causal structure -- a mapping that is crucial to understanding the distinctive kinds of flexibility and control characteristic of truly mindful engagements with the world. Where we confront especially complex interactive causal webs, however, it does indeed become harder to isolate the syntactic vehicles required by the computational approach. Dynamical Systems Theory, I conclude, may play a vital role in recovering such vehicles from the burgeoning mass of real-time interactive complexity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Kennedy Institute of Ethics Journal 10.2 (2000) 175-188 [Access article in PDF] Scope Note 38 Bioethics Resources on the Web * Once described as an "enormous used book store with volumes stacked on shelves and tables and overflowing onto the floor" (Pool, Robert. 1994. Turning an Info-Glut into a Library. Science 266 (7 October): 20-22, p. 20), Internet resources now receive numerous levels of organization, from basic directory listings (...) to elaborate "links" (cross-references to other Internet documents) that flash and glow in the dark. In many ways, the Internet functions as a direct extension of the traditional library. Following linked references across various sites is an electronic version of browsing library stacks, and the serendipitous discoveries made while "surfing the Net" recall the wonders of physically going "book-to-book." Although many of the Internet's best aspects augment library strengths by eliminating physical distance from sources, Net resources pose unique problems for researchers. It is not always clear who is responsible for the content of Web documents, when the document was produced, or how often (if ever) it is updated. Internet resource tools, then, must enable researchers to identify appropriate resources and to evaluate what they find when they get there. Web Research as Taking "Snapshots" Given the Internet's visual nature and fluid content, the process of conducting research on the Web has been likened to taking an informal picture of information on a specific date at a particular time. This metaphor also conveys the "zoom-in" aspect of searching through Web pages by going from general to specific categories. In the first section of this Scope Note, National Reference Center for Bioethics Literature (NRCBL) staff present a snapshot of bioethics resources taken during the spring months of 2000. Entries are divided into the categories of directories, electronic journals, full-text documents, news/current awareness, and teaching resources. In the two subsequent sections, this series of categories is repeated for entries on a specific topic within bioethics-genetics-and again for general search and evaluation tools. Where a Web site may contain pages applicable [End Page 175] to more than one category, multiple entries are made for that site with appropriate information for each category.Much as telecommunication advances have strengthened the relationship of patients and providers as partners, the dynamic nature of the Internet acknowledges that the researcher functions as a librarian whenever accessing the Web. It is our hope that BIOETHICSLINE and the other NRCBL databases not only will enable researchers to search the Web more efficiently, but also will help them to evaluate what they find when they get there. Bioethicsline on the Web: An International Plan in Progress Once only available through libraries, the U.S. National Library of Medicine (NLM), the funding agency for the ongoing development of the BIOETHICS LINE® database from the Kennedy Institute, has provided free Web access to that database of 63,000 citations since September 1998 through Internet Grateful Med. Plans are now underway to eliminate such specialty databases and incorporate all citations into PubMed (for journal articles) or LOCATORplus (for book-like materials and chapters in books). Both of these databases are likewise available at no cost on the Web. In the transition to PubMed and LOCATORplus some features of BIOETHICSLINE that presently are available may be lost. Researchers are encouraged to contact the National Reference Center for Bioethics Literature with search requests or for search strategy assistance with either the current or the future system ([email protected]).The inclusion of bioethics citations in PubMed and LOCATORplus will have several advantages. First, unique keywords from the Bioethics Thesaurus will be considered for inclusion in Medical Subject Headings (MeSH), the indexing vocabulary for PubMed and LOCATORplus, thereby enhancing retrieval of relevant clinical literature by offering more precise terminology covering ethical issues. Second, it will be easier to identify foreign-language materials, which are not currently included in the scope of BIOETHICSLINE. Third, the updating schedule will become more frequent. On the other hand, there may be some loss of searching precision because certain specialized features... (shrink)

Meet the Metaorganism is a web‐based learning app that combines three fundamental biological concepts (coevolution, community dynamics, and immune system) with latest scientific findings using the metaorganism as a central case study. In a transdisciplinary team of scientists, information designers, programmers, science communicators, and educators, we conceptualized and developed the app according to the latest didactic and scientific findings and aimed at setting new standards in visual design, digital knowledge transfer, and online education. A content management system allows continuous integration (...) of new findings, which enables us to expand the app with the dynamics of the research field. Students can thus gain a close insight and connection to current research, and at the same time learn that knowledge is not static but grows dynamically. Especially in the realm of the easily accessible metaorganism research, visualization plays an essential role to keep complex processes understandable and memorable.

PurposeMāori culture is a central aspect inAotearoa/New Zealand's national identity. Beginning in the 1970s biculturalism saw the indigenous culture and values acknowledged and incorporated in wider public discourse and policy. The purpose of this paper is to investigate whether New Zealand's cyberspace accommodates Māori. It explores how the web space is influenced by biculturalism and in turn what an understanding of this web space can tell us about biculturalism inAotearoa.Design/methodology/approachA brief introduction to biculturalism in New Zealand provides the background to (...) the investigation of the country's web space. Recent access statistics enquire whether Māori are actually connected to the internet. The exploration of the structure of the internet is informed by newspaper articles and online documents relating to the development of two Māori specific second‐level domain name spaces. A word‐frequency analysis within a sample of 21 websites provides an overview into the use of the Māori language in cyberspace.FindingsThe paper shows that although Māori have the lowest access rate to the internet compared to other ethnic groups in New Zealand, their influence on the country's web space is nonetheless far‐reaching. Developments regarding Māori language uses over the last years are generally progressive. Māori culture and ongoing social changes are increasingly accommodated on the internet – Māori have been actively shaping the web space. However, these efforts do require the support and acceptance of the wider Internet community. The linguistic and structural developments taking place online since the mid 1990s were influenced by the bicultural thinking, public discourse and practice of the time.Originality/valueThis paper draws together the Māori success‐stories in their endeavour to assert their cultural needs in New Zealand's cyberspace.

In this article, we will firstly explore the concept of connected design; secondly, we will explain how environments can be understood as interfaces for knowledge; and thirdly, we will expose the characteristics and objectives of the project Wired Book & Electronic Margin, which is part of a larger project called Universal Margin, as an example of connective design. Lastly, we will show the benefits of contextualizing information and transforming the world into a connected and lively real-time library, to underline (...) how connected design can facilitate a bottom-up construction of knowledge.

For some decades now, a transformation has been underway that is no less dramatic than the Industrial Revolution, and that just like the latter requires time to be conceptualized. When one seeks to capture the essence of an unprecedented phenomenon, one always uses several, partial, esoteric names: virtuality, Collective Intelligence, Internet, web, big data, artificial intelligence, game… In short, we are all unwittingly drafting a new Visnusahasranāma: a collective poem made up of books, essays, articles, debates, and posts that (...) sings about the thousand names of our Visnu, whose essence however remains unknown. Trying to find a name for this hidden god, I will start from an examination of the current revolution, trying to grasp its specificity, and consequently also its essential differences from the Industrial Revolution; secondly, I will focus on the metaphysical revelation made possible by this revolution (which, like any revolution, does not really transform the world, but rather manifests essential structures that were already present in it, in a hidden or only hinted form); finally, I will devote myself to speculation as to the decisions we must take with respect to the future and the political goals to be pursued with respect to this new world we are living in.

What is W. V. O. Quine’s relationship to classical pragmatism? Although he resists the comparison to William James in particular, commentators have seen an affinity between his “web of belief” model of theory confirmation and James’s claim that our beliefs form a “stock” that faces new experience as a corporate body. I argue that the similarity is only superficial. James thinks our web of beliefs should be responsive not just to perceptual but also to emotional experiences in some cases; Quine (...) denies this. I motivate James’s controversial view by appealing to an episode in the history of medicine when a researcher self-experimented by swallowing a vial of bacteria that at the time had not been studied in much detail. The researcher’s commitment to his own as-yet untested hypothesis was based in part on emotional considerations. Finally, I argue that Quine’s insistence that emotions can never be relevant to adjusting our web of belief reflects a tacit holdover of one of logical positivism’s crucially anti-pragmatist commitments—that philosophy of science should focus exclusively on the context of justification, not the context of discovery. James’s emphasis on discovery as a (perhaps the) crucial locus for epistemological inquiry is characteristic of pragmatism in general. Since Quinean epistemology is always an epistemology of justification, he is not happily viewed as a member of the pragmatist tradition. (shrink)
