The essays by celebrated authors in this 1991 book cover themes fundamental to economics: the influence of benevolence, altruism, justice and religious principles in our treatment of others in society; and the bases of rationality in decision making under conditions of uncertainty. These common themes are given a wide range of perspectives by the contributors, who discuss whether not just a 'rational' but also a 'thoughtful' economic man can be fitted into a sophisticated version of the orthodox model of man (...) as a self-interested maximizer, or whether a radical upheaval in economic analysis is needed to accommodate him. The book is an examination by leading authorities of not only the role of rationality and morals in economics, but also the implications of conventional conceptions of rational economic man for all economic study. It constitutes a powerful argument for greater richness and subtlety in ideas about the motivations of individuals in their economic behaviour. (shrink)

PurposeEven low intensity exercise bouts of at least 15 min can improve feelings of energy and reduce systolic blood pressure. However, little is known about the psychological outcomes of briefer exercise bouts, particularly for modes of exercise that are more intense than level walking, and readily available to many working adults. This study assessed the effects of a 4-min bout of stair walking on FOE and feelings of fatigue.MethodsThirty-six young adult participants were randomized to either stair walking or seated control (...) groups. All participants walked on level-ground from a laboratory to a nearby stairwell and were seated for 4 min before beginning their experimental condition. Stair-walking participants walked up and down one flight of 16 stairs at their own pace for 4 min, while control participants remained seated during that time. Participants walked back to the laboratory for post-condition assessments. Measures of blood pressure, heart rate, rated perceived exertion, and the intensity of feelings of mental energy, mental fatigue, physical energy, and physical fatigue were assessed pre-and post-condition. Separate one-way ANOVAs were conducted on change scores for all variables.ResultsThe stair climbing group experienced significant increases in heart rate [F = 13.167, p < 0.001] and RPE [F = 93.844, p < 0.001] that were not observed in the seated control group. Four minutes of self-paced stair climbing resulted in small changes and non-significant differences within and between groups in blood pressure as well as FOE and FOF.ConclusionAlthough a 4-min self-paced exercise bout can convey short-term physiological health benefits, a 4-min bout of self-paced indoor stair walking in a stairwell was insufficient to lower blood pressure or change subjective FOE and fatigue in a sample that exhibited better than typical FOE and FOF at the pre-test.

This study examined people’s ability to predict and postdict their performance on an event-based prospective memory task. Using nonfocal cues, one group of participants predicted their success at finding animal words and a different group predicted their ability to find words with a particular syllable in it. The authors also administered a self-report questionnaire on everyday prospective and retrospective memory failures. Based on the different strategies adopted by the two groups and correlations among the dependent variables, the authors concluded that (...) people do have a basic awareness of their prospective memory abilities, but that this awareness is far from accurate. The importance of metamemory concerning one’s prospective memory is discussed in terms of how it influences the strategies that people might choose for actually completing their various everyday intentions.

Involvement is an important element of good research and a route to impact. In line with early organizational analysis, we advocate involvement with research stakeholders and investing in the necessary communication and rhetorical skills.

A dramatic illustrated tour of the nation's first five Civil War Battlefield Parks takes readers inside the monuments at Gettysburg, Shiloh, Antietam, Vicksburg, and Chickamauga.

Mormyrid teleosts have Purkinje cells with palisade dendrites, which probably represent coincidence detectors of parallel fiber activity. Their existence strongly supports the ideas of Braitenberg et al. on cerebellar function. However, the organization of mormyrid granule cells and parallel fibers suggests that a key to cerebellar function is not in interactions within one wave, but between twoopposite tidal waves.

On the face of it, the protracted public controversy over abortion in the United States and elsewhere might seem to rest on intractable normative questions inaccessible to economic analysis. But an influential early essay in the now sizable philosophical literature on the subject suggests otherwise. Judith Jarvis Thomson disarmingly inclined toward the view that “the fetus has already become a human person well before birth”,. presumably with all the rights pertaining thereto. She denied, however, that such rights necessarily include use (...) of the mother's womb until birth. To illustrate her point, she compared the mother's situation to that, for example, of an unwilling Good Samaritan with a uniquely suited blood type, who is forced to share a kidney for 9 months with a famous, ailing violinist who needed its use for that duration to recover. Even if the life of a human being was at stake, the assertion of rights for the violinist or the fetus, she argued, would be too degrading for either the Good Samaritan's or the mother's status as a person, where large unwanted sacrifices would be required. Reduced to its economic essentials, the argument is that the mother has property rights to her own body, including the right to expel a “trespasser”. who would die as a consequence. Thus, the antiabortion position is neatly undercut by granting its major premise while denying its conclusion. (shrink)

The role of imagery in encoding event-based prospective memories has yet to be fully clarified. Herein, it is argued that imagery augments a cue-to-context association that supports event-based prospective memory performance. By this account, imagery encoding not only improves prospective memory performance but also reduces interference to intention-related information that occurs outside of context. In the current study, when lure words occurred outside of the appropriate responding context, the use of imagery encoding strategies resulted in less interference when compared with (...) a standard event-based intention condition. This difference was eliminated when participants were not given a specific context to associate their intention . These results support a cue-to-context association account of how imagery operates in certain event-based prospective memory tasks. (shrink)

This paper describes the application of eight statistical and machine-learning methods to derive computer models for predicting mortality of hospital patients with pneumonia from their findings at initial presentation. The eight models were each constructed based on 9847 patient cases and they were each evaluated on 4352 additional cases. The primary evaluation metric was the error in predicted survival as a function of the fraction of patients predicted to survive. This metric is useful in assessing a model’s potential to assist (...) a clinician in deciding whether to treat a given patient in the hospital or at home. We examined the error rates of the models when predicting that a given fraction of patients will survive. We examined survival fractions between 0.1 and 0.6. Over this range, each model’s predictive error rate was within 1% of the error rate of every other model. When predicting that approximately 30°K of the patients will survive, all the models have an error rate of less than 1.5%. The models are distinguished more by the number of variables and parameters that they contain than by their error rates; these differences suggest which models may be the most amenable to future implementation as paper-based guidelines.

Lorsqu’on m’a demandé de commenter mon article « Making news by doing work », je ne l’avais pas relu depuis plusieurs dizaines d’années. Cependant, j’avais l’intuition que mon analyse sur ce qu’on appelle aujourd’hui les « legacy media », les médias traditionnels, s’appliquerait de façon pertinente aux pratiques en pleine évolution des personnes travaillant dans les médias digitaux. Il y a plus de quarante ans, je postulai que les employés des médias traditionnels avaient élaboré des manières...

In this study, we elaborate connections among gender, structure, and practice to suggest how social structural relations shape social sexual practice and, in the process, reshape gender relations. Using survey data from a study of a community mobilization intervention, we investigate the connection between institutional arrangements and condom use practice in sexual encounters with commercial clients and intimate partners among 410 women engaged in sex trade in a semiurban town in southern India. Multinomial logistic regression analysis uncovers the effects of (...) 16 measures of gendered structural relations in three contexts—livelihood resources, household circumstances, and community mobilization intervention priorities. We compare women who practice either consistent or inconsistent condom use with both clients and partners with a reference group of women who practice consistent condom use with clients but not with partners. Results reveal the importance of household and community relations for consistent safer sex practice over and above the organization of sex trade. Our analysis advances gender theory in two interrelated ways: We contribute to gender theorizing in the implementation of health interventions, and to gender change more generally by thinking through possibilities emerging from recursive influences between reordered institutional configurations and altered expectations in interaction.

This book updates and adds to the classic Social Movements of the Sixties and Seventies, showing how social movement theory has grown and changed.

In this remarkable study, David A. J. Richards combines an interpretive history of culture and law, political philosophy, and constitutional analysis to explain the background, development, and growing impact of two of the most important and challenging human rights movements of our time, feminism and gay rights. Richards argues that both movements are extensions of rights-based dissent, rooted in antebellum abolitionist feminism that condemned both American racism and sexism. He sees the progressive role of such radical dissent as an emancipated (...) moral voice in the American constitutional tradition. He examines the role of dissident African Americans, Jews, women, and homosexuals in forging alternative visions of rights-based democracy. He also draws special attention to Walt Whitman's visionary poetry, showing how it made space for the silenced and subjugated voices of homosexuals in public and private culture. According to Richards, contemporary feminism rediscovers and elaborates this earlier tradition. And, similarly, the movement for gay rights builds upon an interpretation of abolitionist feminism developed by Whitman in his defense, both in poetry and prose, of love between men. Richards explores Whitman's impact on pro-gay advocates, including John Addington Symonds, Havelock Ellis, Edward Carpenter, Oscar Wilde, and André Gide. He also discusses other diverse writers and reformers such as Margaret Sanger, Franz Boas, Elizabeth Stanton, W. E. B. DuBois, and Adrienne Rich. Richards addresses current controversies such as the exclusion of homosexuals from the military and from the right to marriage and concludes with a powerful defense of the struggle for such constitutional rights in terms of the principles of rights-based feminism.
