We present a theory of decision by sampling (DbS) in which, in contrast with traditional models, there are no underlying psychoeconomic scales. Instead, we assume that an attribute’s subjective value is constructed from a series of binary, ordinal comparisons to a sample of attribute values drawn from memory and is its rank within the sample. We assume that the sample reflects both the immediate distribution of attribute values from the current decision’s context and also the background, real-world distribution of attribute (...) values. DbS accounts for concave utility functions; losses looming larger than gains; hyperbolic temporal discounting; and the overestimation of small probabilities and the underestimation of large probabilities.

The remarkable successes of the physical sciences have been built on highly general quantitative laws, which serve as the basis for understanding an enormous variety of specific physical systems. How far is it possible to construct universal principles in the cognitive sciences, in terms of which specific aspects of perception, memory, or decision making might be modelled? Following Shepard (e.g.,1987), it is argued that some universal principles may be attainable in cognitive science. Here, 2 examples are proposed: the simplicity principle (...) (which states that the cognitive system prefers patterns that provide simpler explanations of available data); and the scale‐invariance principle, which states that many cognitive phenomena are independent of the scale of relevant underlying physical variables, such as time, space, luminance, or sound pressure. This article illustrates how principles may be combined to explain specific cognitive processes by using these principles to derive SIMPLE, a formal model of memory for serial order (Brown, Neath, & Chater, 2007), and briefly mentions some extensions to models of identification and categorization. This article also considers the scope and limitations of universal laws in cognitive science. (shrink)

What is the origin of individual differences in ideology and personality? According to the parasite stress hypothesis, the structure of a society and the values of individuals within it are both influenced by the prevalence of infectious disease within the society's geographical region. High levels of infection threat are associated with more ethnocentric and collectivist social structures and greater adherence to social norms, as well as with socially conservative political ideology and less open but more conscientious personalities. Here we use (...) an agent-based model to explore a specific opportunities-parasites trade-off hypothesis, according to which utility-maximizing agents place themselves at an optimal point on a trade-off between the gains that may be achieved through accessing the resources of geographically or socially distant out-group members through openness to out-group interaction, and the losses arising due to consequently increased risks of exotic infection to which immunity has not been developed. We examine the evolution of cooperation and the formation of social groups within social networks, and we show that the groups that spontaneously form exhibit greater local rather than global cooperative networks when levels of infection are high. It is suggested that the OPTO model offers a first step toward understanding the specific mechanisms through which environmental conditions may influence cognition, ideology, personality, and social organization.

Is consolidation needed to account for retroactive interference in free recall? Interfering mental activity during the retention interval of a memory task impairs performance, in particular if the interference occurs in temporal proximity to the encoding of the to-be-remembered information. There are at least two rival theoretical accounts of this temporal gradient of retroactive interference. The cognitive neuroscience literature has suggested neural consolidation is a pivotal factor determining item recall. According to this account, interfering activity interrupts consolidation processes that would (...) otherwise stabilize the memory representations of TBR items post-encoding. Temporal distinctiveness theory, by contrast, proposes that the retrievability of items depends on their isolation in psychological time. According to this theory, information processed after the encoding of TBR material will reduce the temporal distinctiveness of the TBR information. To test between these accounts, implementations of consolidation were added to the SIMPLE model of memory and learning. We report data from two experiments utilizing a two-list free recall paradigm. Modeling results imply that SIMPLE was able to model the data and did not benefit from the addition of consolidation. It is concluded that the temporal gradient of retroactive interference cannot be taken as evidence for memory consolidation. (shrink)

Live donor kidney transplantation is the best treatment option for most patients with late-stage chronic kidney disease; however, the rate of living kidney donation has declined in the United States. A consensus conference was held June 5-6, 2014 to identify best practices and knowledge gaps pertaining to live donor kidney transplantation and living kidney donation. Transplant professionals, patients, and other key stakeholders discussed processes for educating transplant candidates and potential living donors about living kidney donation; efficiencies in the living donor (...) evaluation process; disparities in living donation; and financial and systemic barriers to living donation. We summarize the consensus recommendations for best practices in these educational and clinical domains, future research priorities, and possible public policy initiatives to remove barriers to living kidney donation.

Several alternative leadership approaches have been introduced to supplement the long-standing transformational leadership model as concerns have grown that it did not place enough emphasis on leader ethics. Nonetheless, to establish the value of the newer approaches, evidence of conceptual and empirical distinctiveness is required. Though meta-analysis has been somewhat helpful in this regard :517–536, 2016), we conducted two within-study comparisons of ethical leadership, virtuous leadership and key components of TL reflected by socialized charismatic leadership. We predicted that these alternative (...) models differ in the strength of their ties to a range of valued outcomes. Our analyses of 230 leader–follower dyads based predominately in North America and US-based 131 dyads left many hypotheses unsupported; nonetheless, there was evidence of differential associations. For example, across both samples, in the context of all three models, follower-rated ethical leadership was the only significant predictor of follower-rated leader effectiveness, leader-rated subordinate in-role performance, and leader-rated follower ethicality. As hypothesized, virtuous leadership was the strongest predictor of self-rated leader happiness in Sample 1, but contrary to expectations, in Sample 2, only the TL components were related to happiness and life satisfaction among both leaders and followers.

Recent claims that the Christian tradition justifies destructive research on human embryos have drawn upon an article by the late Professor Gordon Dunstan which appeared in this journal in 1984. Despite its undoubted influence, this article was flawed and seriously misrepresented the tradition of Christian reflection on the moral status of the human embryo.

Objective: To assess the adequacy of the process of informed consent for surgical patients at the University Hospital of the West Indies. Method: The study is a prospective, cross-sectional, descriptive study. 210 patients at the University Hospital of the West Indies were interviewed using a standardised investigator-administered questionnaire, developed by the authors, after obtaining witnessed, informed consent for participation in the study. Data were analysed using SPSS V.12 for Windows. Results: Of the patients, 39.4% were male. Of the surgical procedures, (...) 68.6% were scheduled, 7.6% urgent and 23.8% emergency, 35.2% were minor and 64.8% major. Information imparted/received was acceptable in 40% of cases, good in 24% and inadequate (unacceptable) in 36% of cases. Almost all (97.6%) patients stated that they understood why an operation was planned and 93.3% thought that they had given informed consent. Most (95.2%) thought that they had free choice and made up their own mind. A quarter (25.2%) of all patients were told that it was mandatory for them to sign the form. There was a discussion of possible side effects and complications in 56.7% of patients. Conclusions: This study clearly indicates that surgical patients at the University Hospital of the West Indies feel that they have given informed consent. However, it also suggests that more information should be given to patients for consent to be truly informed. (shrink)

Responsible Research and Innovation provides a framework for judging the ethical qualities of innovation processes, however guidance for researchers on how to implement such practices is limited. Exploring RRI in the context of nanotechnology, this paper examines how the dispersed and interdisciplinary nature of the nanotechnology field somewhat hampers the abilities of individual researchers to control the innovation process. The ad-hoc nature of the field of nanotechnology, with its fluid boundaries and elusive membership, has thus far failed to establish a (...) strong collective agent, such as a professional organization, through which researchers could collectively steer technological development in light of social and environmental needs. In this case, individual researchers cannot innovate responsibly purely by themselves, but there is also no structural framework to ensure that responsible development of nanotechnologies takes place. We argue that, in such a case, individual researchers have a duty to collectivize. In short, researchers in situations where it is challenging for individual agents to achieve the goals of RRI are compelled to develop organizations to facilitate RRI. In this paper we establish and discuss the criteria under which individual researchers have this duty to collectivize. (shrink)

Despite a long history in eastern and western culture of defining leadership in terms of virtues and character, their significance for guiding leader behavior has largely been confined to the ethics literature. As such, agreement concerning the defining elements of virtuous leadership and their measurement is lacking. Drawing on both Confucian and Aristotelian concepts, we define virtuous leadership and distinguish it conceptually from several related perspectives, including virtues-based leadership in the Positive organizational behavior literature, and from ethical and value-laden leadership. (...) Then, two empirical studies are presented that develop and validate the Virtuous Leadership Questionnaire, an 18-item behaviorally based assessment of the construct. Among other findings, we show that the VLQ accounts for variance in several outcome variables, even after self-assessed leader virtue and subordinate-rated social and personalized leader charisma are controlled.

The most discussed and most significant issue on the religious scene today is whether it is possible, or even desirable, to believe in God. Mr. Kaufman's valuable study does not offer a doctrine of God, but instead explores why God is a problem for many moderns, the dimensions of that problem, and the inner logic of the notion of God as it has developed in Western culture. His object is to determine the function or significance of talk about God: how (...) the concept of God is generated in human experience; the special problems in turn generated by this concept (for example, the intelligibility of the idea of transcendence, the problem of theodicy) and how they are met; and under what circumstances the idea of God is credible or important or even indispensable. He does not try to prove God's existence or nonexistence, but elucidates what the concept of God means and the important human needs it fulfills. Four of the eleven essays have been previously published, at least in part; seven are completely new. (shrink)

This paper's purpose is to assess how management's perceptions regarding certain aspects of environmental reporting relate to the firm's actual reporting strategy. Toward that end, we propose a model where a firm's environmental disclosure is conditional upon executive assessments of corporate concerns. The study relies on a survey that was sent to environmental management executives from European and North American multinational firms enquiring about the determinants of corporate environmental disclosure. Responses from these executives were then contrasted with their firms' actual (...) environmental reporting practices, which was measured using a comprehensive multi-criteria grid. Results show that there is a relationship between environmental managers' attitudes toward various stakeholder groups and how those managers respond to the stakeholders via the decision to disclose and the actual disclosures made. Our model provides a perspective as to how a firm responds to the numerous stakeholders to whom it must be accountable. This accountability in turn relates to how the company communicates its actions to society in order to achieve or maintain its social legitimacy. (shrink)

Scientific evolutionary/ecological thinking is the basis for today's understanding that we are now in an ecological crisis. Religions, however, often resist reordering their thinking in light of scientific ideas, and this presents difficulties in trying to develop a viable global ecological ethic. In both the West and Asia religiomoral ecological concerns continue to be formulated largely in terms of traditional concepts rather than in more global terms, as scientific thinking about ecological matters might encourage them to do. The majority of (...) this article is devoted to the kind of reformulation of Western Christian conceptions of God, humanity, and the relation between them that is necessary to address this problem. The question is then raised whether similar critical thinking about religiomoral issues raised by today's evolutionary/ecological scientific thinking is going on in Asian religions and whether it would be too presumptuous (in view of our colonial history) for us Westerners to ask for such rethinking. This leads to a final question: Without such transformations in religious traditions East and West, is the development of a truly global ecological ethic really feasible? (shrink)

Current discussions of “evidentialism” seem to presuppose essentially traditional theistic conceptions and formulations. For many theologians. however, these have become problematic because of (a) the rise of a new consciousness of the significance of religiouspluralism; (b) the emergence of theories about the ways in which our symbolic frames of orientation shape all our experiencing and thinking; (c) a growing awareness that significant responsibility for some of the major evils of the twentieth century must be laid to ourreligious traditions. Since recent (...) discussion of “evidentialism” continues to employ traditional symbols and concepts without sensitivity to these matters, it has not attracted much interest among contemporary theologians.

Individual differences in the mere willingness to think analytically has been shown to predict religious disbelief. Recently, however, it has been argued that analytic thinkers are not actually less religious; rather, the putative association may be a result of religiosity typically being measured after analytic thinking (an order effect). In light of this possibility, we report four studies in which a negative correlation between religious belief and performance on analytic thinking measures is found when religious belief is measured in a (...) separate session. We also performed a meta-analysis on all previously published studies on the topic along with our four new studies (N = 15,078, k = 31), focusing specifically on the association between performance on the Cognitive Reflection Test (the most widely used individual difference measure of analytic thinking) and religious belief. This meta-analysis revealed an overall negative correlation (r) of -.18, 95% CI [-.21, -.16]. Although this correlation is modest, self-identified atheists (N = 133) scored 18.7% higher than religiously affiliated individuals (N = 597) on a composite measure of analytic thinking administered across our four new studies (d = .72). Our results indicate that the association between analytic thinking and religious disbelief is not caused by a simple order effect. There is good evidence that atheists and agnostics are more reflective than religious believers. (shrink)

This article has two parts, as the title suggests. The first sketches what I call biohistorical naturalism, a naturalistic position in which it is emphasized that the historicocultural development of our humanity, particularly our becoming linguistic/symbolical beings, is as central to our humanness as the biological evolutionary development that preceded (and continues to accompany) it. Apart from such a biohistorical emphasis (or its equivalent), naturalistic positions cannot give adequate accounts of human religiousness. The second part suggests that, although it would (...) not be consistent with biohistorical naturalism to continue thinking of God in the traditional supernaturalistic way as “the Creator,” it would be quite appropriate to understand God as the ongoing creativity (of truly novel realities) manifest in the long history of the universe, particularly in the evolution of life on Earth.

The anthropocentric orientation of traditional understandings of Christian faith and life, further accentuated by the existentialist terms in which theology was articulated in mid‐century by Tillich and others, produced theologies no longer appropriate in today's world of evolutionary and ecological thinking about human existence and its embeddedness in the web of life on planet Earth. This problem can be addressed with the help of several new concepts that enable us to understand both humanity‐in‐the‐world and God in ways in keeping with (...) these present conceptions, thus providing a more intelligible and illuminating way of understanding Christian faith and life today.

There are religious thinkers of Kierkegaard's ilk who concede that their belief in an afterlife is the expression of a wish and an offense to the understanding. Freud could not agree more. The collision that this essay plots comes when a Freud and a Kierkegaard try to decide what the individual is to do with such inherently human, unrealistic desires. Freud urges us to forsake all wish?fulfilling thoughts of everlasting life; however, this requires nothing less than the acceptance of imminent, (...) everlasting death. This is a difficult thought to think I half argue, half insist. The question is raised as to whether or not psychoanalysis can help us come to terms with the reality it compels us to face. A negative conclusion is reached. (shrink)
