Malgré les déclarations d'intention et les efforts des écologistes, la planète est en danger. Ses ennemis cherchent un profit immédiat à empoisonner l'air, les sols et l'eau, à abattre les arbres et les animaux. Ils trouvent un intérêt à détruire la réalité pour lui substituer un monde virtuel contrôlable. Cet essai invite à établir de nouvelles relations entre la planète et les hommes.

The contents and structure of semantic memory have been the focus of much recent research, with major advances in the development of distributional models, which use word co‐occurrence information as a window into the semantics of language. In parallel, connectionist modeling has extended our knowledge of the processes engaged in semantic activation. However, these two lines of investigation have rarely been brought together. Here, we describe a processing model based on distributional semantics in which activation spreads throughout a semantic network, (...) as dictated by the patterns of semantic similarity between words. We show that the activation profile of the network, measured at various time points, can successfully account for response times in lexical and semantic decision tasks, as well as for subjective concreteness and imageability ratings. We also show that the dynamics of the network is predictive of performance in relational semantic tasks, such as similarity/relatedness rating. Our results indicate that bringing together distributional semantic networks and spreading of activation provides a good fit to both automatic lexical processing (as indexed by lexical and semantic decisions) as well as more deliberate processing (as indexed by ratings), above and beyond what has been reported for previous models that take into account only similarity resulting from network structure.

Health care institutions have paid increasing attention to preventing nosocomial transmission of influenza through vaccination of health care personnel. While multifaceted voluntary interventions have increased vaccination rates, proponents of mandatory programs contend the rates remain unacceptably low. Conventional bioethical analyses of mandatory programs are inadequate; they fail to account for the obligations of nonprofessional personnel or to justify the weights assigned to different ethical principles. Using an ethics framework for public health permits a fuller analysis. The framework's focus on fairness (...) accentuates the potential differences between the risk of transmitting infection and employment status, and the need to equitably evaluate exemptions. The framework's emphasis on balancing benefits and burdens highlights the need to justify a specific goal and questions the need to exclude all nonmedical exemptions. While mandatory vaccination programs are justifiable, greater attention should be paid to their implementation. (shrink)

This paper seeks to address the relation of materiality to structure and phenomena of signification or semiosis. It examines the logical consequences of several major lines of argument concerning the status of semiosis with regards to the human or broadly “organic” life-world and to the “zero degree” of base materiality — from Peirce to Lotman and Sebeok — and questions the classificatory rationale that delimits semiosis to the exclusion of a general treatment of dynamic systems. Recent investigations into neurosemiotics have (...) provided salient arguments for the need to treat semiosis as a characteristic of systems in general, and to establish a more transverse understanding of signifiability upon the basis of what makes dynamic structures, as such, possible.

An examination of how the Accelerationist imagination has failed in its deviation from Nick Land's radical metaphorics of an Artaudian and Bataille-esque signifying “economy without reserve” to a neo-Sovietised bureaucratic plan for the post-Anthropocene, per Benjamin Noys et al. Given a positivistic guise, futurology of the latter kind almost always masks a return of apocalyptic humanism. The fantasy of a species unified in solidarity, in full view of its techno-evolutionary obsolescence, seeks to magically transform the history of alienation into some (...) transcendental “means” of global post-production: but what this amounts to in fact is the phantasmatic extension of the Situationist spectacle into a “collective” dream of living on beyond a “global” extinction event which, in reality, will have been nothing but that of an ideology.

A number of recent models of semantics combine linguistic information, derived from text corpora, and visual information, derived from image collections, demonstrating that the resulting multimodal models are better than either of their unimodal counterparts, in accounting for behavioral data. Empirical work on semantic processing has shown that emotion also plays an important role especially in abstract concepts; however, models integrating emotion along with linguistic and visual information are lacking. Here, we first improve on visual and affective representations, derived from (...) state‐of‐the‐art existing models, by choosing models that best fit available human semantic data and extending the number of concepts they cover. Crucially then, we assess whether adding affective representations (obtained from a neural network model designed to predict emojis from co‐occurring text) improves the model's ability to fit semantic similarity/relatedness judgments from a purely linguistic and linguistic–visual model. We find that, given specific weights assigned to the models, adding both visual and affective representations improves performance, with visual representations providing an improvement especially for more concrete words, and affective representations improving especially the fit for more abstract words.

: The film "Who Should Survive?: One of the Choices on Our Conscience" contains a dramatization of the death of an infant with Down syndrome as the result of the parents' decision not to have a congenital intestinal obstruction surgically corrected. The dramatization was based on two similar cases at The Johns Hopkins Hospital and was financed by the Joseph P. Kennedy, Jr., Foundation. When "Who Should Survive?" was exhibited in 1971, the public reaction was generally critical of the parents' (...) decision and the physicians' inaction. Although technological developments in medicine were a necessary condition for the production of this film and its unanticipated reception, they were not a sufficient condition. The proximate cause was a changed understanding of the capabilities of individuals with Down syndrome. Part of the impetus for this change was data showing the adverse effects of institutionalization on normal children. (shrink)

Corporate governance guidelines are a mechanism that a firm can enact which should reduce agency costs and better align the interests of boards and the suppliers of capital. This study examines stock price reactions primarily attributable to institutional investors occurring when corporations announce the enactment of corporate governance guidelines. A final sample of 77 firms was derived from the first announcement of corporate governance guidelines exclusive to the SEC-EDGAR database. The results indicate that good governance does matter. Firms that announced (...) the enactment of corporate governance guidelines experienced increased stock prices following the announcements. There was an immediate (days 1–4) reaction for firms that provided all or part of the guidelines’ substance; a delayed (days 8–10) reaction occurred for those firms that only referenced the guidelines’ enactment. Additionally, firms with either a potentially greater following or that had a previous history of acrimonious relations with stakeholders were rewarded by the announcement of the enactment of guidelines.

We examined the relationship between sleep and the affective components of subjective well-being as well as psychological well-being, and between sleep and academic performance, of full-time undergraduate students in a residential college at the National University of Singapore. The aspects of sleep considered were self-reported sleep duration, sleep efficiency, frequency of sleep disturbances, daytime dysfunction, sleep latency and overall sleep quality, as measured by the Pittsburgh Sleep Quality Index. Academic performance was measured using self-reported cumulative average point scores, typically known (...) as grade point average in other institutions. Psychological well-being and the affective components of subjective well-being were assessed using the Flourishing Scale and the Scale of Positive and Negative Experience, respectively. With the exception of sleep latency, our univariate analysis revealed significant associations between the abovementioned facets of sleep, and the affective components of subjective well-being. The analysis also revealed significant associations between the above sleep variables and psychological well-being, except sleep latency and frequency of sleep disturbances. Only daytime dysfunction was found to be significantly correlated with academic performance in our univariate analysis. In addition, our multivariate analysis shows that psychological well-being, affect balance and academic performance each has a direct effect on overall sleep quality. The relationship between overall sleep quality and psychological well-being is U-shaped, while that between overall sleep quality and affect balance is linear and moderated by psychological well-being. The relationship between overall sleep quality and academic performance is either U-shaped or an inverted-U, depending on the level of psychological well-being, which moderates the relationship. These nonlinear relationships indicate that individuals with the highest levels of psychological well-being are not the best sleepers, neither are the highest academic achievers necessarily the best sleepers.

It is shown here that the microcanonical ensemble for a system of noninteracting bosons and fermions contains a subensemble of state vectors for which all particles of the system are distinguishable. This “IQC” (inner quantum-classical) subensemble is therefore fully classical, except for a rather extreme quantization of particle momentum and position, which appears as the natural price that must be paid for distinguishability. The contribution of the IQC subensemble to the entropy is readily calculated, and the criterion for this to (...) be a good approximation to the exact entropy is a logarithmically strengthened form of the usual criterion for the validity of classical statistics in terms of the thermal de Broglie wavelength and the average volume per particle. Thus, it becomes possible to derive the Maxwell-Boltzmann distribution directly from the ensemble in the classical limit, using fully classical reasoning about the distinguishability of particles. The entropy is additive—theN! factor of the Boltzmann count cancels out in the course of the calculation, and the “N! paradox” is thereby resolved. The method of “correct Boltzmann counting” and the lowest term of the Wigner-Kirkwood series for the partition function are seen to be partly based on the IQC subensemble, and their partly nonclassical nature is clarified. The clear separation in the full ensemble of classical and nonclassical components makes it possible to derive the classical statistics of indistinguishable particles from their quantum statistics in a controlled, explicit way. This is particularly important for nonequilibrium theory. The treatment of molecular collisions along too-literally classical lines turns out to require exorbitantly high temperatures, although there are suggestions of indirect ways in which classical nonequilibrium theory might be justified at ordinary temperatures. The applicability of exact classical ergodic and mixing theory to systems at ordinary temperatures is called into question, although the general idea of coarse-graining is confirmed. The concepts on which the IQC idea is based are shown to give rise to a series development of thermostatistical quantities, starting with the distinguishable-particle approximation. (shrink)

Background: While employers are increasingly considering and implementing COVID-19 vaccination requirements, little is known about the reasons offered by employees seeking religious exemptions.Methods: We conducted a mixed methods analysis of all the requests for religious exemptions submitted during the initial implementation of a COVID-19 vaccination requirement at a single academic medical center in the United States.Results: Five hundred sixty-five (3.4%) employees requested religious exemptions. At least 305 (54.0%) requesters had job titles suggesting that they had direct patient contact. Four hundred (...) ninety-nine (88.3%) of requesters self-identified as Christian, of whom 120 (21.2%) identified as Roman Catholic. Requesters offered 0 to 8 (mean 2.7) categories of reasons for their request. The most frequently stated reasons pertained to the use of fetal cell lines in vaccine development and manufacturing (382, 67.6%), interest in maintaining purity (221, 39.1%), or belief in divine healing (172, 30.4%). Some requesters also volunteered evidence of the sincerity of their beliefs including examples of their religious practices (116, 20.5%), other practices (66, 11.7%), and emotional states (32, 5.7%). One hundred fifty-two applications (26.9%) contained text copied without attribution, primarily from sample religious exemption request letters available on the Internet.Conclusions: Most requesters focused on the use of fetal cell lines in the development or manufacturing of the vaccines as the justification for their request. The development of vaccines that are not reliant on fetal cell lines may increase vaccination rates. Understanding reasons for religious exemption requests may inform vaccine education and vaccination policies. (shrink)

This paper is addressed to recent theoretical discussions of the Anthropocene, in particular Bernard Stiegler’s Neganthropocene (Open Universities Press, 2018), which argues: “As we drift past tipping points that put future biota at risk, while a post-truth regime institutes the denial of ‘climate change’ (as fake news), and as Silicon Valley assistants snatch decision and memory, and as gene-editing and a financially-engineered bifurcation advances over the rising hum of extinction events and the innumerable toxins and conceptual opiates that Anthropocene Talk (...) fascinated itself with—in short, as ‘the Anthropocene’ discloses itself as a dead-end trap…”. The objective of this paper is therefore twofold: (1) to discuss how the Anthropocene is appropriated to certain ideological discourses (paradoxically) to maintain the hegemony of precisely those systems of production that have most accelerated climate change etc.; (2) to consider how the factography of the Anthropocene is exploited in this process to mask the ideological character of industry-aligned “technocratic” environmental management. The paper is not concerned with specific case studies in terms of government and industry policy, or climate science, but rather with the ways in which the discourse of the Anthropocene has been inflected within the humanities and the broader cultural field—that is to say, ideologically, as a system or logic of meaning. How the Anthropocene “means” is, in this respect, a question of some importance. This paper does not attempt to address all the facets of this question, but focuses upon a central “apocalyptic” strain in the discourse of the Anthropocene drawn particularly from Francis Fukuyama’s millennial posthumanism and centred in the question of “sustainability” as catastrophe management—with the risk that real environmental degradation will become an alibi for a revived neoliberalism. In other words, that the critical Earth system transformations that characterise the Anthropocene are themselves commodities, and that the project of their amelioration is in process of defining a future (opportunistic) “crisis” rhetoric with a global political franchise. The ideological import of the Anthropocene stems precisely from the fact that it is planetary and, while catalysed by human agency, independent in its specific behaviour from it. The Anthropocene objectively presents as the contemporary counterpart of the Cold War doctrine of Mutually Assured Destruction and the most compelling argument for a new kind of technological “arms race.” But it also presents as the condition of an emerging ideological discourse which will determine how this race is run. From the discourse on “energy security” to the widespread “security crackdown” on environmental activists across the so-called developed & developing world, the Anthropocene has come to represent the co-option of a scientific factography for the thinly disguised resurgence of “ideological science” of the Fukuyamaesque variety (post-history, post-human). For Fukuyama, the true meaning of “posthuman” is thus the accomplishment of humanity’s historical mission. As the “End of History” designates an end of ideological struggle, so too the dénouement of the Anthropocene and the “ends of man” represent the accomplished purpose of species warfare: dominion, not simply over the world, but over all possible worlds. According to this narrative, science—like technology—must be uniquely at the service of the maintenance of the global order, organised around a universal appeal to “crisis management.” It is precisely for this reason that what calls itself post-human masks the return of an ever-more-apocalyptic Humanism.
