The aim of the present research was to develop a difficulty model for logical reasoning problems involving complex ordered arrays used in the Graduate Record Examination. The approach used involved breaking down the problems into their basic cognitive elements such as the complexity of the rules used, the number of mental models required to represent the problem, and question type. Weightings for these different elements were derived from two experimental studies and from the reasoning literature. Based on these weights, difficulty (...) models were developed which were then tested against new data. The models had excellent predictive validity and showed the relative influence of rule based factors and factors relating to the number of underlying models. Different difficulty models were needed for different question types, suggesting that people used a variety of approaches and, at a wider level, that both mental models and mental rules may be used in reasoning.

In October 1984, Bruno Huisman stated with regards to Jean Cavaillès, ‘Let us be honest, or at least realistic: today, one can be a professor of philosophy without ever having read a single line of Cavaillès. Often invoked, sometimes quoted, the oeuvre of Cavaillès is little attended for itself’ (Huisman 1984). As for Albert Lautman, it would seem that the situation is even more extreme. In 1994, the publisher Hermann, under the impetus of Bruno Huisman and George Canguilhem, collected almost (...) the totality of the Jean Cavaillès papers in one volume (Oeuvres complètes de philosophie des sciences (Cavaillès 1994)). But, the Essai sur l’unité des mathématiques et divers écrits (Lautman 1977), published by the Union générale d’Éditions in 1977, had all but disappeared by the early 1980s and yet was never republished! This will remain one of the great indignities of French publishing, for as Jean Petitot rightly affirms: ‘Regarded as too speculative, in spite of his exceptional mathematical scholarship and his close connection with Hilbertian axiomatic structuralism, his mathematical philosophy has, until now, been devoid of any particular attention …. We would like to state clearly from the start, Albert Lautman represents, in our view, without exaggeration, one of the most inspired philosophers of this century’ (Petitot 1987, 79-80). (shrink)
DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

Gold Stripe on a Jackass is a conceptually rich description of one naval officer's career journey. Author Stephen B. Sloane began his career in Annapolis, where the commandment of obedience holds sway, and finished in Berkeley, a place where questioning authority is woven deeply into the cultural fabric.
A comparison of the engineering schools at UC Berkeley and Stanford during the 1940s and 1950s shows that having an excellent academic program is necessary but not sufficient to make a university entrepreneurial. Key factors that made Stanford more entrepreneurial than Cal during this period were superior leadership and a focused strategy. The broader institutional context mattered as well. Stanford did not have the same access to state funding as public universities and some private universities. Therefore, in order to gather (...) resources, Stanford was forced to become entrepreneurial first, developing business skills at the same time Cal was developing political skills. Stanford ’s early development of entrepreneurial business skills played a crucial role in the development of Silicon Valley. (shrink)
As the world’s religious communities become more involved in environmental concerns, the question arises as to whether their most significant contributions are in the realm of worldviews, doctrine, and cosmology, or rather in the realm of political and economic critique and an articulation of social justice concerns arising from ecological despoliation. After reviewing liberation theology’s early critique of economic developmentalism, as well as its more recent treatment of ecological concerns, this paper suggests that liberation theology is in fact positing a (...) cosmological as well as political and economic critique of modernity, which proffers conduits of dialogue with other environmental approaches.

This article examines selected behavioral aspects of ethical decision making within a business context. Three categories of antecedents to ethical decision behaviors (individual differences, interpersonal variables, and organizational variables) are examined and propositions are offered. Moral development theory and expectancy theory are then explored as possible bases for a theory of ethical decision making. Finally, means of improving ethical decision making in firms are explored.
Socially and politically significant Muslim communities are posing a challenge to the public spheres of Western Europe: can public reason in a liberal democracy be so conceived as to accommodate the religious reasons of Muslims and other religiously motivated citizens? This question, often discussed from the perspective either of political philosophy or of particular religious traditions, is addressed here instead by drawing on the theory and practice of inter-religious dialogue. The dialogue movement known as ‘scriptural reasoning’ is analysed for its (...) potential to provide a way of conceptualising the nature of reasoning in the public sphere. ‘Reasoning with texts’, it is argued, is a way of describing much of the reasoning that takes place within the public sphere and not just religious reasoning. This approach to understanding public reasoning is established through a combination of example and theory. A model of communicative hermeneutics as public reason based on an textual rationality is proposed. As well as providing space for textually based religious arguments, this textual imagination can be situated alongside and complement postmodern developments of Jürgen Habermas’s conception of the public sphere. Whilst this approach to reasoning in the public sphere initially appears very different from the classic statement of the idea of public reason in John Rawls’s political liberalism, it is shown to have significant continuity with Rawls’s theory when this is viewed through the lens of the Supreme Court as exemplar of public reason. This highest level of public reason involving legislation is also a form of reasoning with texts. But in order for religious and more popular levels of public discourse and deliberation to impact on the political and legislative processes, these too must be conceived as modes of reasoning having some continuity with higher levels of public reasoning. It is such continuity that this thesis seeks to theorise. (shrink)
As Post observes, accounting firms are unique among multinationals. They are more likely than firms in almost any other category to go abroad. They also have less choice in location as their expansion is determined largely by the desired locations of their clients. Given the widespread global presence of such firms, it can be argued that the global audit firm is uniquely at risk from variations in ethical perceptions across nations. This study extends the U.S. accounting literature on determinants of (...) cheating among accounting students to the U.K. Based on the work of Cohen et al. it develops a model that suggests that students in lower "uncertainty avoidance" countries will be both less likely to cheat, and when they do cheat, will be driven by internal rather than external mode. Our results supported the model as proposed as our results indicated that U.S. students were more likely to cheat and were more responsive to external stimuli than were the U.K. students. (shrink)
Peirce was greatly influenced by Aristotle, particularly on the topic of final cause. Commentators are therefore right to draw on Aristotle in the interpretation of Peirce's teleology. But these commentators sometimes fail to distinguish clearly between formal cause and final cause in Aristotle's philosophy. Unless form and end are clearly distinguished, no sense can be made of Peirce's important claim that 'desires create classes.' Understood in the context of his teleology, this claim may be considered Peirce's answer to nominalists and (...) sceptics on the possibility and status of scientific knowledge. On the basis of an improved view of Peirce's teleology, the objection that inorganic physical events do not admit of teleological explanation can be answered. I argue that the non-teleological alternative leaves the laws of nature and the actions of inorganic matter unexplained. (shrink)
Currently the focus of a heated debate among indigenous peoples, human rights advocates, crop breeders, pharmaceutical companies, conservationists, social scientists, and lawyers, the proposal would allow impoverished people in biologically rich areas to realize an economic return from resources under their care. Monetary compensation could both validate their knowledge and provide them with an equitable reward for sharing it, thereby compensating biological stewardship and encouraging conservation.
This fourth edition of Law in Context not only updates the text by reference to the latest thinking and developments in the broad area of 'law in context', but also introduces readers to the wider social, political and regulatory contexts of law.Bottomley and Bronitt, as in previous editions, expose readers to the multitude of contexts (some explicit, others implicit) that affect how law is made, broken and enforced by the state or individual citizens. The fundamental ideals of law - such (...) as the Rule of Law - rest on cherished liberal values, though the authors constantly encourage readers not to accept uncritically the rhetoric of law, but to test these assumptions through empirical eyes.This contextual and critical approach to law, laid out in Chapter 1 and 2, is further developed through specific studies of Gender and Race. Complementing these substantive critiques of law, later chapters examine some of the institutional limitation of law and justice through chapters on access to justice, the law-making process, and regulation. The final chapter, which serves as an epilogue, looks to the broader challenges for law in an age of globalisation through case studies on terrorism and global business regulation. (shrink)
There are some conspicuous differences between the sensibilities of cutaneous and visceral tissues: (1) Direct trauma, which readily produces pain when applied to the skin, is mostly without effect in healthy visceral tissue. (2) Pain that arises from visceral tissues is initially often poorly localised and diffuse. (3) With time, visceral pains are often referred to more superficial structures. (4) The site of referred pain may also show hyperalgesia. (5) In disease states, the afflicted viscera may also become hyperalgesic. In (...) this target article, I consider to what extent differences in the physiology, anatomy, and chemistry of peripheral processing systems explain these different sensibilities. In almost every aspect, there are subtle differences in the properties of the processing mechanisms for cutaneous and visceral information. These may arise because of distinct developmental cues operating in the two domains. Many of the differences between visceral and cutaneous afferents are quantitative rather than qualitative. The quantitative differences, for example in the density of afferent innervation, can be large. The quantitative differences in the numbers of afferents alone may be a sufficient explanation for some aspects of the differential sensibility, for example, the poor localisation of sensation and the apparent insensitivity to focal yet tissue- damaging stimuli. In addition, the few clear qualitative differences apparent in the innervations of the two tissue types may be of special importance. That the encoding of visceral nociceptive events may occur by an intensity mechanism rather than a specificity mechanism could be the key difference in viscerosensory and somatosensory processing.

Philosopher Martin Heidegger and German poets who evoke nature offer excellent introductions to elemental earth. Those poets privilege earth among the elements using their earthy language. Heidegger views earth as the hidden ground of things. The article approaches elemental earth through Heidegger’s analysis of what he views as Georg Trakl’s crucial line of poetry about earth: “something strange is the soul on earth.” Heidegger stresses the soul as the stranger. In contrast, this article argues that on the basis of a (...) contextual analysis of Trakl’s poetry and some other German poetry, it is the earth that is strange. Forgotten earth is the background out of which and the foundation upon which things manifest themselves. Elemental earth makes possible human experience of space and place. (shrink)
Cholinergic-rich grafts have been shown to be effective in restoring maze-learning deficits in rats with lesions of the forebrain cholinergic projection system. However, the relevance of those studies to developing novel therapies for Alzheimer's disease is questioned.
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)
It is well established that neural grafts can exert functional effects on the host animal by a multiplicity of different mechanisms – by diffuse release of trophic molecules, neurohormones, and deficient neurotransmitters, as well as by growth and reformation of neural circuits. Our challenge is to understand how these different mechanisms complement each other.
BackgroundHuman infection studies are valuable in vaccine development. Deliberate infection, however, creates challenging questions, particularly in low and middle-income countries where HIS are new and ethical challenges may be heightened. Consultation with stakeholders is needed to support contextually appropriate and acceptable study design. We examined stakeholder perceptions about the acceptability and ethics of HIS in Malawi, to inform decisions about planned pneumococcal challenge research and wider understanding of HIS ethics in LMICs.MethodsWe conducted 6 deliberative focus groups and 15 follow-up interviews (...) with research staff, medical students, and community representatives from rural and urban Blantyre. We also conducted 5 key informant interviews with clinicians, ethics committee members, and district health government officials.ResultsStakeholders perceived HIS research to have potential population health benefits, but they also had concerns, particularly related to the safety of volunteers and negative community reactions. Acceptability depended on a range of conditions related to procedures for voluntary and informed consent, inclusion criteria, medical care or support, compensation, regulation, and robust community engagement. These conditions largely mirror those in existing guidelines for HIS and biomedical research in LMICs. Stakeholder perceptions pointed to potential tensions, for example, balancing equity, safety, and relevance in inclusion criteria.ConclusionsOur findings suggest HIS research could be acceptable in Malawi, provided certain conditions are in place. Ongoing assessment of participant experiences and stakeholder perceptions will be required to strengthen HIS research during development and roll-out. (shrink)
The role that personality plays in the justification of organizational sabotage behavior was examined. In a two phase study, 120 business students were first surveyed to create a list of 51 methods of sabotage. In the second phase, 274 other business students rated justifiability of the 51 methods and completed Machiavellian and hostility scales. A factor analysis of the justification ratings yielded four factors: (1) methods of sabotaging company profits and production, (2) informational sabotage, (3) violent and illegal methods, and (...) (4) traditional labor methods of sabotage. A 2 (high versus low Machiavellianism) ×2 (high versus low hostility) ANOVA upon factor scores for justifiability revealed significant main effects for hostility and significant interactive effects on Factors 1 and 2. Results were discussed in terms of differences in management and blue collar methods of sabotage and in terms of a self-presentational approach to justification of sabotage. (shrink)
Objectives: To analyse and compare the surveys on German doctors and judges on end of life decision making regarding their attitudes on the advance directive and on the dying process.Design: The respondents were to indicate their agreement or disagreement to eight statements on the advance directive and to specify their personal view on the beginning of the dying process.Participants: 727 doctors in three federal states and 469 judges dealing with guardianship matters all over Germany.Main measurements: Comparisons of means, analyses of (...) variance, pivot tables and factor analyses .Results: Three attitude groups on advance directive were disclosed by the analysis: the decision model, which emphasises the binding character of a situational advance directive; the deliberation model, which puts more emphasis on the communicative aspect; and the delegation model, which regards the advance directive as a legal instrument. The answers regarding the beginning of the dying process were broadly distributed, but no marked difference was observed between the responding professions. The dying process was assumed by most participants to begin with a life expectancy of only a few days.Conclusions: A high degree of valuation for advance directive was seen in both German doctors and judges; most agreed to the binding character of the situational directive. Regarding the different individual concepts of the dying process, a cross-professional discourse on the contents of this term seems to be overdue. (shrink)
