Ethical disputes arise over differences in the content of the ethical beliefs people hold on either side of an issue. One person may believe that it is wrong to have an abortion for financial reasons, whereas another may believe it to be permissible. But, the magnitude and difficulty of such disputes may also depend on other properties of the ethical beliefs in question—in particular, how objective they are perceived to be. As a psychological property of moral belief, objectivity is relatively (...) unexplored, and we argue that it merits more attention. We review recent psychological evidence which demonstrates that individuals differ in the extent to which they perceive ethical beliefs to be objective, that some ethical beliefs are perceived to be more objective than others, and that both these sources of variance are somewhat systematic. This evidence also shows that differences in perceptions of objectivity underpin quite different psychological reactions to ethical disagreement. Apart from reviewing this evidence, our aim in this paper is to draw attention to unanswered psychological questions about moral objectivity, and to discuss the relevance of moral objectivity to two issues of public policy.

Given a basic conditional of the form, If A then C, individuals usually list three cases as possible: A and C, not‐A and not‐C, not‐A and C. This result corroborates the theory of mental models. By contrast, individuals often judge that the conditional is true only in the case of A and C, and that cases of not‐A are irrelevant to its truth or falsity. This result corroborates other theories of conditionals. To resolve the discrepancy, we devised two new tasks: (...) the “collective” truth task, in which participants judged whether sets of assertions about a specific individual, such as: If A then C, not‐A, C, could all be true at the same time; and one in which participants judged the truth of conditional predictions about specific future events. The results consistently matched the three possibilities, thereby corroborating the model theory. They also showed a massive violation of the probability calculus in estimates of the probabilities of the four cases in the partition of conditionals (A and C, A and not‐C, not‐A and C, and not‐A and not‐C), which summed to over 200%.

Inferences about spatial, temporal, and other relations are ubiquitous. This article presents a novel model-based theory of such reasoning. The theory depends on 5 principles. The structure of mental models is iconic as far as possible. The logical consequences of relations emerge from models constructed from the meanings of the relations and from knowledge. Individuals tend to construct only a single, typical model. They spontaneously develop their own strategies for relational reasoning. Regardless of strategy, the difficulty of an inference depends (...) on the process of integration of the information from separate premises, the number of entities that have to be integrated to form a model, and the depth of the relation. The article describes computer implementations of the theory and presents experimental results corroborating its main principle. (shrink)

We draw on the behavioral agency model to explore the ethical consequences of CEO equity incentives. We argue that CEOs are more concerned with funding pension plans when they have more to gain from their stock options yet will increasingly underfund employee pension funds as their current option wealth increases. Our findings reveal that both effects hold when the CEO has greater power (also occupying board chair) over firm decision making. Our study suggests that there is an ethical dimension to (...) equity incentives, given they are intended to align CEO interests with shareholders, yet potentially incentivize CEO behaviors with adverse consequences for employees. Insights from our findings provide boards and regulators with behavioral levers to protect employee well-being in the context of pension funding. (shrink)

The DNA in human cells is continuously undergoing damage as consequences of both endogenous processes and exposure to exogenous agents. The resulting structural changes can be repaired by a number of systems that function to preserve genome integrity. Most pathways are multicomponent, involving incision in the damaged DNA strand and resynthesis using the undamaged strand as a template. In contrast, O6-alkylguanine-DNA alkyltransferase is able to act as a single protein that reverses specific types of alkylation damage simply by removing the (...) offending alkyl group, which becomes covalently attached to the protein and inactivates it. The types of damage that ATase repairs are potentially toxic, mutagenic, recombinogenic and clastogenic. They are generated by certain classes of carcinogenic and chemotherapeutic alkylating agents. There is consequently a great deal of interest in this repair system in relation to both carcinogenesis and cancer chemotherapy.

A repulsive core force is derived which, assuming π mesons are the field particles, gives binding energies in good agreement with binding energies per nucleon of heavy nuclei. The physical model consists of a field of relatively short range, in which emission of a π meson by a nucleon and subsequent absorption by a neighboring nucleon is equivalent to a potential well. The binding energy at the equilibrium spacing of the nucleons is the self-energy of the π mesons, which is (...) calculated by analogy with classical electric fields. (shrink)

Moral patients deserve moral consideration and concern – they have moral standing. What factors drive attributions of moral standing? Understanding these factors is important because it indicates how broadly individuals conceptualize the moral world, and suggests how they will treat various entities, both human and non-human. This understanding has recently been advanced by a series of studies conducted by both psychologists and philosophers, which have revealed three main drivers of moral standing: the capacity to suffer, intelligence or autonomy, and the (...) nature of an entity's disposition. These studies have also revealed causal links between moral standing and other variables of interest, namely, mental state attributions and moral behavior. In this review, I consider this recent research, aiming to clarify what the balance of evidence indicates about how moral standing is judged and about its links to mind perception and behavior. I conclude by suggesting open questions for future research on this exciting topic. (shrink)

Ever since the constitutional revolution of the 1930s, constitutional law and theory have been dominated by questions of civil rights. The expansion of rights under the Warren Court constituted a deep-seated shift in judicial attitudes that has proved remarkably stable over time. Despite protests in some quarters that the Burger Court and the current Rehnquist Court have undermined civil rights recognized during the Warren Court era, the fact is that the changes have been surprisingly marginal. Even precedents that were widely (...) believed to be endangered species a decade ago – such as Miranda and Roe v. Wade – continue in force, although they have indeed been pruned back. Despite their importance, however, these high-profile cases do not go to the core of the Supreme Court's agenda. The core is epitomized by Brown v. Board of Education on the one hand, representing an aggressive and interventionist attitude toward government discrimination against discrete minorities, and footnote four of the Carotene Products case, on the other hand, representing an extraordinarily deference to the political process with respect to economic regulation. The Rehnquist Court's commitment to this core agenda is not dramatically different than that of its predecessors, at least not when the broad sweep of constitutional law is taken into account.

Prior research on the psychology of retribution is complicated by the difficulty of separating retributive and general deterrence motives when studying human offenders . We isolate retribution by investigating judgments about punishing animals, which allows us to remove general deterrence from consideration. Studies 2 and 3 document a “victim identity” effect, such that the greater the perceived loss from a violent animal attack, the greater the belief that the culprit deserves to be killed. Study 3 documents a “targeted punishment” effect, (...) such that the responsive killing of the actual “guilty” culprit is seen as more deserved than the killing of an almost identical yet “innocent” animal from the same species. Studies 4 and 5 extend both effects to participants' acceptance of inflicting pain and suffering on the offending animal at the time of its death, and show that both effects are mediated by measures of retributive sentiment, and not by consequentialist concerns.

Perception of (and during) events is a necessary feature of any perceptual theory. Norman's dual-process approach cannot account for the perception of events without substantial interactions between the dorsal and ventral systems. These interactions, as outlined by Norman, are highly problematical. The necessity for interactions between the two systems makes the distinction useless.

Following important work by Pizarro, Uhlmann and Salovey (2003) on moral judgments of uncontrolled/impulsive versus controlled/ deliberate action, we focus on the related issue of the moral evaluation of emotion-motivated versus principle-driven behavior. We examine: (a) the potential lesser blameworthiness of antisocial acts perceived as driven by emotion as opposed to principle; (b) how factors governing the moral evaluation of antisocial acts might extend to the evaluation of prosocial acts; and (c) how overriding a moral emotion in favor of a (...) moral principle affects moral attributions.

The model identifies a spatial coordinate frame within which the sensorimotor apparatus produces movement. Its spatial nature simplifies its coupling with spatial reference frames used concurrently by vision and proprioception. While the positional reference frame addresses the performance of spatial tasks, it seems to have little to say about movements involving energy expenditure as the principle component of the task.

Roger Shepard's description of an abstract representational space defined by landmark objects and kinematic transformations between them fails to successfully capture the essence of the perceptual tasks he expects of it, such as object recognition. Ultimately, objects are recognized in the context of events. The dynamic nature of events is what determines the perceived kinematic behavior, and it is at the level of dynamics that events can be classified as types. [Shepard].

With a focus on the areas of theory, literature, culture, society and film, this collection of essays examines, questions and broadens the applicability of Postcolonialism and Islam from a multifaceted and cross-disciplinary perspective.Topics covered include the relationship between Postcolonialism and Orientalism, theoretical perspectives on Postcolonialism and Islam, the position of Islam within postcolonial literature, Muslim identity in British and European contexts, and the role of Islam in colonial and postcolonial cinema in Egypt and India. At a time at which Islam (...) continues to be at the centre of increasingly heated and frenzied political and academic deliberations, Postcolonialism and Islam offers a framework around which the debate on Muslims in the modern world can be centred.Transgressing geographical, disciplinary and theoretical boundaries, this book is an invaluable resource for students of Islamic Studies, Cultural Studies, Sociolgy and Literature.

Sudoku puzzles, which are popular worldwide, require individuals to infer the missing digits in a 9 9 array according to the general rule that every digit from 1 to 9 must occur once in each row, in each column, and in each of the 3-by-3 boxes in the array. We present a theory of how individuals solve these puzzles. It postulates that they rely solely on pure deductions, and that they spontaneously acquire various deductive tactics, which differ in their difficulty (...) depending on their “relational complexity”, i.e., the number of constraints on which they depend. A major strategic shift is necessary to acquire tactics for more difficult puzzles: solvers have to keep track of possible digits in a cell. We report three experiments corroborating this theory. We also discuss their implications for theories of reasoning that downplay the role of deduction in everyday reasoning. (shrink)

It is argued that promissory obligation arising from the contract of employment offers a simpler and less contentious explanation and justification of the doctor-nurse relationship at work, than does May's proposal of second-order reasons. The second-order reason position is rejected as the norm for that relationship, and in the exceptional case, where it is admitted, shared employee status is identified as primary validator of a doctor as locus of rational authority. Finally, a brief case is made for a more precise (...) vocabulary to describe the doctor-nurse relationship, as a contribution to more collegial relations. (shrink)

Books and articles about the acceleration of daily life are themselves accelerating. A theoretical basis for expecting the inevitability of these trends has been traced in the writings of major sociologists including Durkheim, Marx, Weber and Sorkin. As deTocqueville observed more than 150 years ago, “The American is always in a hurry.” Economists have also weighed in on these issues of time compression, perhaps starting with Linder’s insightful treatise The Harried Leisure Class, predicting the frantic pace of modern life and (...) leisure. As specialized work led to higher rates of productivity, accelerated consumption led to an acceleration of the pace of life and a harried leisure class. Much of what Linder discussed in regard to time scarcity was perceived scarcity. Interestingly, his conclusions were not that people would work longer, but rather that they would attempt to increase the yield on a unit of time in all areas of life—minimizing activities such as singing or political debate, which could not easily have their yield on time spent increased. The value of efficiency and increased productivity, carried to extremes, he argued, produced a kind of decadence in which the goal of economic growth is never questioned. More recently, economists have played down the seriousness of concerns over a speeded up lifestyle, characterizing it in large part as “Yuppie Kvetch.” Not that higher income couples are making irrational decisions, they are simply facing the inevitable constraints on their ability to enjoy their wealth. This article reviews various of these philosophical issues in the context of US national survey data concerning trends in the time pressures and stress in the activities of Americans over the last 30+ years. It focuses both on the measurable amounts of free time Americans have and on the specific activities done in that free time. It also reviews survey data on Americans’ perceptions of and attitudes toward time and stress. It brings together data from different survey sources that often show conflicting trends and conclusions. (shrink)

From self-cultivation to global justice, from environmental ethics to the interrelation of religion and science, this collection of essays highlights the central role of philosophy, and comparative philosophy in particular, for understanding and appreciating the connections and discontinuities of East and West.

A better understanding of how schistosomes exploit host nutrients, neuro‐endocrine hormones and signalling pathways for growth, development and maturation may provide new insights for improved interventions in the control of schistosomiasis. This paper describes recent advances in the identification and characterisation of schistosome tyrosine kinase and signalling pathways. It discusses the potential intervention value of insulin signalling, which may play an important role in glucose uptake and carbohydrate metabolism in schistosomes, providing the nutrients essential for parasite growth, development and, notably, (...) female fecundity. Significant progress has also been made in the characterisation of other schistosome growth factor receptors, such as transforming growth factor beta receptor and epidermal growth factor receptor, and in our understanding of their roles in the host‐parasite molecular dialogue and parasite development. The use of parasite signal transduction components as novel vaccine or drug targets may prove invaluable in prevention, treatment and control strategies to combat schistosomiasis. (shrink)

Schistosomes are parasitic blood flukes, responsible for significant human disease in tropical and developing nations. Here we review information on the organization of the cytoskeleton and associated motor proteins of schistosomes, with particular reference to the organization of the syncytial tegument, a unique cellular adaptation of these and other neodermatan flatworms. Extensive EST databases show that the molecular constituents of the cytoskeleton and associated molecular systems are likely to be similar to those of other eukaryotes, although there are potentially some (...) molecules unique to schistosomes and platyhelminths. The biology of some components, particular those contributing to host–parasite interactions as well as chemotherapy and immunotherapy are discussed. Unresolved questions in relation to the structure and function of the tegument relate to dynamic organization of the syncytial layer. BioEssays 26:752–765, 2004. © 2004 Wiley Periodicals, Inc.

The crisis in donor organ and tissue supply is one of the most difficult challenges for transplant today. New policy initiatives, such as the driver's license option and requiredrequest, have been implemented in many states, with other initiatives, such as mandatedchoice and presumedconsent, proposed in the hopes of ameliorating this crisis. At the same time, traditional acquisition of organs from human cadavers has been augmented by living human donors, and nonheartbeating human donors, as well as experimental animal and artificial sources. (...) Despite these efforts, the crisis persists and is perhaps most tragic when it threatens the lives of children, driving parents to sometimes desperate measures. Herein, we address one very controversial step some parents have taken to obtain matching tissue or organs for their needy children—that is, having a child, in part, for the purpose of organ or tissue procurement.
