Electrical resistivity and ac-calorimetric measurements reveal a complex magnetic phase diagram for single crystals of the ferromagnetic Kondo-lattice compound CeAgSb2 at high pressures up to 80 kbar. The ferromagnetic order at TC = 9.6 K at ambient pressure is completely suppressed at a critical pressure PC = 35 kbar. Another magnetic transition, possibly antiferromagnetic, found above 27 kbar, attains a maximum value TN 6 K at 44 kbar and then appears to be completely suppressed by 50 kbar. Thermodynamic and transport (...) measurements in the ferromagnetic state indicate an energy gap Δ 30 K in the spin-wave excitation spectrum at ambient pressure which decreases to Δ 10 K at P = 30 kbar. No superconductivity is observed at ambient pressure above T 0.1 K, under applied pressure in the ferromagnetic state (P = 28.5 kbar), nor in the antiferromagnetic state (P = 33 − 46 kbar) above 0.3 K. © 2003 The American Physical Society.

Rendell and Whitehead note the necessary, complementary relationship between field and laboratory studies in other species, but conclude their article by de-emphasizing the role of laboratory findings in cetacean research. The ambiguity in field studies of cetaceans should argue for greater reliance on the laboratory, which has provided much of the available research supporting the hypothesis of cetacean culture.

Macphail’s comparative approach to intelligence focused on associative processes, an orientation inconsistent with more multifaceted lay and scientific understandings of the term. His ultimate emphasis on associative processes indicated few differences in intelligence among vertebrates. We explore options more attuned to common definitions by considering intelligence in terms of richness of representations of the world, the interconnectivity of those representations, the ability to flexibly change those connections, knowledge, and individual differences. We focus on marine mammals, represented by the amphibious pinnipeds (...) and the aquatic cetaceans and sirenians, as animals that transitioned from a terrestrial existence to an aquatic one, experiencing major changes in ecological pressures. They adapted with morphological transformations related to streamlining the body, physiological changes in respiration and thermoregulation, and sensory/perceptual changes, including echolocation capabilities and diminished olfaction in many cetaceans, both in-air and underwater visual focus, and enhanced senses of touch in pinnipeds and sirenians. Having a terrestrial foundation on which aquatic capacities were overlaid likely affected their cognitive abilities. Vocal and behavioral observational learning capabilities in the wild and in laboratory experiments suggest versatility in group coordination. Empirical reports on aspects of intelligent behavior like problem-solving, spatial learning, and concept learning by various species of cetaceans and pinnipeds, suggest rich cognitive abilities. The high energy demands of the brain suggest brain-intelligence relationships might be fruitful areas for the study when specific hypotheses are considered, e.g., brain mapping indicates hypertrophy of specific sensory areas in marine mammals. Modern neuroimaging techniques provide ways to study neural connectivity, and the patterns of connections between sensory, motor, and other cortical regions provide a biological framework for exploring how animals represent and flexibly use information in navigating and learning about their environment. At this stage of marine mammal research, it would still be prudent to follow Macphail’s caution that it is premature to make strong comparative statements without more empirical evidence, but an approach that includes learning more about how animals flexibly link information across multiple representations could be a productive way of comparing species by allowing them to use their specific strengths within comparative tasks.

Transcending all ideological differences, the Book of Metamorphoses (Yijing, I-Ging) has been viewed in traditional Chinese culture as a basic work not only of the art of sooth-saying, but of an understanding of the world as a whole. Among the 64 situations described therein, the 56th deals with the constellation of ‘the wanderer’ (Lü). It is symbolized by the ‘fire’ above the ‘mountain’, i.e., a fleeting phenomenon whose ephemeral character is highlighted by the fact that it appears above something as (...) solid and immovable as a mountain.

© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

This article offers a view on the emerging practice of managing external relations of the modern university, and the role of science communication in this. With a representative sample of research universities in four countries, we seek to broaden our understanding of the _science communication (SC) function_ and its niche within the modern university. We distinguish science communication from corporate communication functions and examine how they distribute across organisational levels. We find that communication functions can be represented along a spectrum (...) of (de)centralisation: public relations and marketing activities are more likely carried out at the central level (central offices), and public affairs and SC activities are more likely carried out at decentral levels (e.g. in specific offices and/or research institutes, departments). This study shows that little attention is paid to science communication at central structures, suggesting that it is not a practice that aligns easily with university corporate communication, yet SC might find its niche increasingly in decentral locations of activity.

To investigate the impact of framing on rule-breaking behavior in social dilemmas, we incorporated a rule in a one-shot resource game with two framing-treatments: One frame was a give-some dilemma (i.e., a variant of a public goods game) and the other frame a take-some dilemma (i.e., a variant of a commons dilemma game). In each frame, all participants were part of one single collective sharing a common good. Each participant was initially equipped with one of five different endowments of points (...) from which they must give/could take amounts to/from the common good. The exact amounts of contributions/withdrawals were regulated by the rule. Participants decided whether to cooperate and comply with the rule or to break the rule to their own advantage and at the expense of the collective (i.e., giving lower/taking higher amounts). Results of an online-experiment with 202 participants showed a significantly higher proportion of individuals breaking the rule in the take-some frame than in the give-some frame. In addition, endowment size influenced the proportion of rule-breaking behavior in the take-some frame. However, the average amounts of points not given/taken too much were not different between the frames. (shrink)

Retrieval of relevant unstructured information from the ever-increasing textual communications of individuals and businesses has become a major barrier to effective litigation/defense, mergers/acquisitions, and regulatory compliance. Such e-discovery requires simultaneously high precision with high recall (high-P/R) and is therefore a prototype for many legal reasoning tasks. The requisite exhaustive information retrieval (IR) system must employ very different techniques than those applicable in the hyper-precise, consumer search task where insignificant recall is the accepted norm. We apply Russell, et al.’s cognitive task (...) analysis of sensemaking by intelligence analysts to develop a semi-autonomous system that achieves high IR accuracy of F1 ≥ 0.8 compared to F1 < 0.4 typical of computer-assisted human-assessment (CAHA) or alternative approaches such as Roitblat, et al.’s. By understanding the ‘Learning Loop Complexes’ of lawyers engaged in successful small-scale document review, we have used socio-technical design principles to create roles, processes, and technologies for scalable human-assisted computer-assessment (HACA). Results from the NIST-TREC Legal Track’s interactive task from both 2008 and 2009 validate the efficacy of this sensemaking approach to the high-P/R IR task. (shrink)

To investigate the impact of framing on rule-breaking in social dilemmas, we incorporated a rule in a 1-shot resource game with 2 framing treatments: in one frame, we offered a give-some dilemma (i.e., a variant of a public goods game), and in the other frame, a take-some dilemma (i.e., a variant of a commons dilemma game). In each frame, all participants were part of 1 single collective sharing a common good. Each participant was initially equipped with 1 of 5 different (...) endowments of points from which they must give/were allowed to take amounts to/from the common good. The rule established outcome equality between participants by prescribing the exact amounts of what to give/take to/from the common good, which was finally divided equally among participants. Participants decided whether to cooperate and comply with the rule or to break the rule to their own advantage and to the detriment of the collective (i.e., giving lower/taking higher amounts). The results of an online experiment with 202 participants showed a significantly higher proportion of individuals breaking the rule in the take-some dilemma than in the give-some dilemma. In addition, endowment size influenced the proportion of rule-breaking behavior in the take-some dilemma. However, the average amounts of points not given/taken too much were not different between the 2 dilemma types. (shrink)

The subjective time of an instrumental action is shifted towards its outcome. This temporal binding effect is partially retrospective, i.e., occurs upon outcome perception. Retrospective binding is thought to reflect post-hoc inference on agency based on sensory evidence of the action – outcome association. However, many previous binding paradigms cannot exclude the possibility that retrospective binding results from bottom-up interference of sensory outcome processing with action awareness and is functionally unrelated to the processing of the action – outcome association. Here, (...) we keep bottom-up interference constant and use a contextual manipulation instead. We demonstrate a shift of subjective action time by its outcome in a context of variable outcome timing. Crucially, this shift is absent when there is no such variability. Thus, retrospective action binding reflects a context-dependent, model-based phenomenon. Such top-down re-construction of action awareness seems to bias agency attribution when outcome predictability is low. (shrink)

Verteilungsgerechtigkeit befasst sich mit der Verteilung von Gütern innerhalb einer Gruppe, wobei verschiedene Verteilungsprinzipien und -ergebnisse als mögliche Ideale einer solchen Verteilung verhandelt werden. Diese normativen Ansätze sind oft rein verbal formuliert, wodurch ihre Anwendung auf unterschiedliche konkrete Verteilungssituationen, die hinsichtlich ihrer Gerechtigkeit beurteilt werden sollen, häufig schwer fällt. Eine Möglichkeit, fein abgestufte Gerechtigkeitsbeurteilungen verschiedener Verteilungen präzise erfassen zu können, besteht in der formalen Modellierung solcher Ideale durch Maße oder Indizes. Die Auswahl eines geeigneten Maßes, das ein gewisses Ideal abbilden (...) soll, muss ihrerseits eine Fundierung erfahren, was durch die Forderung von begründeten Axiomen erreicht werden kann, denen ein Maß genügen soll. In der vorliegenden Arbeit werden solche Axiome für Maße der Verteilungsgerechtigkeit am Beispiel von Bedarfsgerechtigkeit eingeführt. Ferner werden exemplarische Maße der Bedarfsgerechtigkeit vorgestellt. Damit wird für die Beurteilung und Modellierung von Maßen der Verteilungsgerechtigkeit eine erste diskutable Grundlage gelegt.

Needs play a key role in many fields of social sciences and humanities, ranging from normative theories of distributive justice to conceptions of the welfare state. Over time, different conceptions of what counts as a need (i. e., what is considered a normatively relevant need) have been proposed. Many of them include (in one way or the other) needs for survival, decency, belonging, and autonomy. Little work has been done on how these kinds of needs are evaluated in terms of (...) their significance for distributive justice. To begin closing this gap, we investigate the role of the four aforementioned kinds of needs for impartial observers. We do so in two empirical studies. The first study asks participants to evaluate the importance of each of the four kinds of needs separately. We find that different levels of importance are attributed to the kinds of needs, which places them in a hierarchy. The second study asks participants to make distributive decisions. Results further support the hierarchy found in the first study and, additionally, reveal that participants tend to make coherent allocation decisions. (shrink)

The formal part of this chapter is concerned with measures of need-based justice. According to the measures we propose, a distribution is unjust (i) the more it deviates from absolute need satisfaction and equal degrees of need satisfaction, (ii) the more the given undersupply could have been mitigated by transfers, or (iii) the more resources are used for oversupply instead of need satisfaction. These measures are compared, i.e., as to the satisfaction of need-oriented relatives of axioms prominent in poverty measurement; (...) and we have a critical eye on the proposals of Jasso and Miller. The empirical part reports on three vignette studies conducted to find out how people evaluate the justice of given distributions and how they distribute goods when aiming at justice. The main goal was to measure the significance ascribed to need. This significance was compared with the significance ascribed to effort or equality; and it was shown that a need’s influence decreases when the corresponding person is accountable for having a higher amount of it. In the third study, we found out that needs that are not directed at bare survival, such as the need for participation in social life, are attributed lower degrees of importance. The chapter concludes with some implications of our research for a theory of need-based justice. (shrink)

The dispositional properties encountered in everyday experience seem to have causal bases in other properties, e.g., the microstructure of a vase is the causal basis of its fragility. In contrast, the Pure Dispositions Thesis maintains that some dispositions require no causal basis. This thesis faces the Problem of Being: without a causal basis, there appears to be no grounds for the existence of pure dispositions. This paper establishes criteria for evaluating the problem, critically examines four theories of the being of (...) pure dispositions, and develops an explanation of how a pure disposition grounds itself via its own power.

Does exploration of the gut microbiota–brain axis expand our understanding of what it means to be human? Recognition and conceptualization of a gut microbiota–brain axis challenges our study of the nervous system. Here, integrating gut microbiota–brain research into the metaorganism model is proposed. The metaorganism—an expanded, dynamic unit comprising the host and commensal organisms—asserts a radical blurring between man and microbe. The metaorganism nervous system interacts with the exterior world through microbial‐colored lenses. Ongoing studies have reported that gut microbes contribute (...) to brain function and pathologies, even shaping higher neurological functions. How will continued collaborative efforts (e.g., between neurobiology and microbiology), including partnerships with the arts (e.g., philosophy), contribute to the knowledge of microbe‐to‐mind interactions? While this is not a systemic review, this nascent field is briefly described, highlighting ongoing challenges and recommendations for emerging gut microbiota–brain research.

This book offers the first comparative account of the changes and stabilities of public perceptions of science within the US, France, China, Japan, and across Europe over the past few decades. The contributors address the influence of cultural factors; the question of science and religion and its influence on particular developments (e.g. stem cell research); and the demarcation of science from non-science as well as issues including the incommensurability versus cognitive polyphasia and the cognitive (in)tolerance of different systems of knowledge.

Background: Informed consent is a legal as well as ethical prerequisite in clinical research. For dementia research, informed consent can be a problem if subjects with dementia, whose capacity for understanding and thus also decision making might be limited, are to be exam- ined. This might result in exclusion of dementia patients from research, as capacity for understanding and decision making are often equated with the ability for rational decision making. However, this valuation has been criticized at times for attaching (...) too much impor- tance to the cognitive aspect of decision making. -/- Methods: This qualitative study investigates the actual consent procedure of a clini- cal research study in Germany with regard to dementia patients’ subjective and objective understanding of informed consent information. Research participants were ten dementia patients, who volunteered in two clinical research studies, as well as their caregivers. Data were collected by use of semi-structured interviews. -/- Results: It was determined that the patients’ comprehension of informed consent infor- mation was rather limited. However, a number of patients were quite aware of this. In con- trast, all caregivers claimed to have fully understood the provided information, while their objective comprehension was also incomplete. Several participants indicated that they did not attach much importance to the information given in the consent procedure and that their consent did not primarily depend on this information. Rather, participation in the research study for them seemed to be more of a problem-focused coping strategy for dealing with their diagnosis of dementia. -/- Conclusion: For research ethics these results raise the question whether the currently prevailing emphasis on the cognitive aspect of autonomous decision making, i.e., compre- hension, may be too one-sided, and to what extent the “volitional” aspect in giving consent should be given greater consideration.

One of the most important Italian witness of Auschwitz explains what it means to live an experience characterized by the sorrow for the massacre of one’s family and by all the people whom one has seen to die; an experience that is backed up by the hope, very soon to be broken, that what one has seen and suffered can be a warning. The only thing to do is to repeat, in each school, the live existence of the children who (...) we have seen to walk towards the gas chamber, in order for her memory to survive, for a little while still.

To ascribe a telos is to ascribe a norm or standard of performance. That fact underwrites the plausibility of, say, teleological theories of mind. Teleosemantics, for example, relies on the normative character of teleology to solve the problem of “intentional inexistence”: a misrepresentation is just a malfunction. If the teleological ascriptions of such theories to natural systems, e.g., the neurological structures of the brain, are to be literally true, then it must be literally true that norms can exist independent of (...) intentional and psychological agency. Davies, for one, has argued that such norms are impossible within a naturalistic worldview. Consequently, teleological theories of mind, for example, cannot be literally true. I will show, however, that the truth conditions on normative statements do not presuppose intentional and psychological agency and, further, that a selectional regime is one naturalistic mechanism that satisfies those truth conditions. Norms, then, exist in the world independent of intentional and psychological agency. (shrink)

Is it Possible to Experiment with Thought? Ernst Mach’s Notion of Thought Experiment and its Pedagogical Context around 1900. The article tries to establish the crucial importance of the pedagogical dimension of Ernst Mach’s ideas on experimenting with thought. The focus on contemporary pedagogics demonstrates, first, that Mach’s didactic approach to physics is part of a much broader stream of pedagogical writings that transcends national and disciplinary borders and comprises a diversity of authors, e.g. Wilhelm Jerusalem, William James or Alfred (...) N. Whitehead; second, that the much‐heralded controversy between Mach and the French philosopher of science Pierre Duhem about thought experiments does not only revolve around epistemological issues but rather stems from their antagonist vision of teaching physics; and finally, third, that G. Stanley Hall’s psychogenetic theory of pedagogics bears a strong resemblance with the evolutionary naturalism of Machian epistemology and helps explaining key tenets of Mach’s conception of thought experiment. By establishing a broad convergence between the work of all these authors despite their different academic upbringing, background and nationality the article argues for a complex and historically fine‐grained vision of the relations between natural, social and human sciences going beyond dichotomies like ‘Erklären’ and ‘Verstehen’ or the ‘Two Cultures’.

Los procesos educativos deben asumir de modo expreso, reflexiva y críticamente nuestros ethos originarios (histórica, filosófica y antropológicamente hablando), las condiciones de marginalidad y exclusión de la mayoría de la población mundial, y la de nuestro país dentro de la planificación del desarrollo global. Y deben, desde esta reflexión, asumir el progreso científico y tecnológico que se transfiere y realiza, en los diferentes países como en las universidades, teniendo como fin la satisfacción de nuestras necesidades integrales, y no la inserción (...) de la dominación cultural y la explotación económica. En este libro, el método analéctico está tomado, no como receta mágica, sino como instrumento de análisis, intervención y transformación de la subjetividad y de la realidad. No está abordado como una esencia que pueda totalizarse, de allí la mayor inquietud de desplegarlo en las demás dimensiones teórico-prácticas, ya que en ese mismo despliegue se hace posible la articulación transformadora con la realidad socio-histórica en sus distintas facetas.

People living in rural areas make up 20 percent of the U.S. population, but only 9 percent of physicians practice there. This uneven distribution is significant because rural areas have higher percentages of people in poverty, elderly people, people lacking health insurance coverage, and people with chronic diseases. As a way of ameliorating these disparities, e-health initiatives are being implemented. But the rural e-health movement raises its own set of distributive justice concerns about the digital divide. Moreover, even if the (...) digital divide is overcome, e-health services may be of an inferior quality compared to face-to-face medical encounters. In this paper, I argue that before we can fully understand the distributive justice implications of e-health, we must first understand what distributive justice means. I argue that five elements—fairness, quality, accessibility, availability, and efficiency—constitute a general conception of justice and that all of these elements must be considered when evaluating e-health for rural health profession shortage areas. In doing so, it may be necessary to make important tradeoffs among these elements. I then examine the development of e-health programs in light of Rawls’s principle of equal opportunity and Daniels’s notion of species-typical functioning. I conclude that in the context of e-health, Rawls’s principle should be expanded to include geography as a prima facie morally relevant criterion for allocating healthcare benefits. I also conclude that Daniels’s notion of species-typical functioning provides grounds for thinking of health and some healthcare services as special goods. (shrink)

High-profile organizations often emphasize fixed giftedness rather than malleable effort-based criteria as critical for excellent achievements. With giftedness being primarily associated with White or Asian males, such organizational implicit theories of excellence may shape individuals’ sense of belonging depending on the extent to which they match the gifted White/Asian male prototype, i.e., the prototypical gifted person which is typically imagined to be a White or Asian male. Previous research has reported fixed excellence theories emphasizing giftedness to impair the sense of (...) belonging of females and negatively stereotyped ethnic minorities. We investigate the combined effects of gender and ethnicity. We predicted that, while individuals whose gender and ethnicity do not match the gifted prototype show a reduced sense of belonging in fixed organizations, White/Asian males who match the gifted prototype show the opposite effect, experiencing a higher sense of belonging in fixed organizations. In an experimental study, we manipulated advertising material used by a highly selective academic institution in Germany and tested effects on students’ belonging. Whereas the original material emphasized giftedness as essential for excelling, our manipulated version stressed effort. As expected, females from stereotyped ethnic minority groups felt less belonging in the fixed organization, while White/Asian males anticipated stronger belonging in the fixed organization. Fixed views of excellence impair negatively stereotyped individuals’ belonging but may even strengthen the belonging of prototypical academic elites. (shrink)

Marcels Konzeption des Du zielt auf Anerkennungsverhältnisse, die der sprachlichen Interaktion vorgängig sind und grenzt sich vom idealistischen Konzept einer abstrakten transzendentalen Subjektivität ab. Die Verweigerung von Anerkennung wird von Marcel kritisiert, weil sich der Einzelne so aus dem Bereich gelebter Intersubjektivität ausschließe und unzugänglich mache.
