Abstract. The global pandemic of HIV/AIDS is the most significant challenge of our time. The ongoing conversation between religion and science comes to a critical juncture in this pandemic. The global community has not yet found a vaccine or cure for this virulent virus, which will likely claim five million more lives in the coming year. The global statistics challenge even the most sophisticated imagination, with projections in the tens of millions of people dead, orphaned children, and many more living in various stages of incapacitation or diminished lives. There is a common prophetic religious imperative among Western faith communities that urgently requires both science and religion to respond. Both disciplines define their scope and purpose as universal, and the global pandemic provides a significant challenge to that universal claim. Regardless of the many differences among the nations and peoples challenged by this pandemic, there is a common moral foundation to which the Western religious and scientific traditions must respond. Religion and science cannot deny their respective social responsibilities by claiming the role of neutral bystander. There are several critical ethical choices to be made in response to the pandemic, and the disciplines of religion and science are critical in formulating those choices. 相似文献

In this paper fascination phenomenologically is described as a state of radically being captured by an imposing object. What is left of the impoverished and paralysed subject clings to the exclusive fascinating object. Fascination is the eye of the storm of extreme ambivalence towards an exclusive object: being the only remaining object it is necessary for living in an object world, but at the same time it is threatening to life by absorbing the subject totally. So the subject is sucked in by a yet frightening object. From a metapsychological point of view fascination is understood as the congealed result of excessive projective identification and a strong confusional state connected with it: the subject empties itself so much in the object that it comes to stand for the subject. The fascinating object embodies in a condensed way – as a special form of a bizarre object – split off unconscious threatening material. So fascination is linked to the Kleinian theory of anxiety. Two clinical vignettes illustrate how states of fascination can be understood as an ultimate defence against unconscious menacing material welling up. The hypothesis is developed that fascination points to a revelation of fundamental psychic truth that promptly cramps the subject because the reintegration of it is felt as annihilating. In the vignettes this takes the form of a ‘transformation in hallucinosis’. Fascination is at the same time ‘the moment of truth’ and possibly a serious obstruction of the analytic process. This unconscious truth seems to concern primitive ‘superego violence’. The challenge consists in thawing the frozen fascinating object by linking it to other material. 相似文献

The objective of this work was to investigate the influence perturbation direction has on postural responses during overground gait, and whether these responses are age related. Differences in stepping patterns following perturbations of the support surface were examined in the frontal and sagittal planes during forward walking. Eleven young and 10 older adults completed Mini BESTest, hip strength tests, and 45 perturbed walking trials, triggered on heel contact. Lateral perturbations were more challenging to postural stability for both groups. Step length measures showed young adults recovered in the step proceeding the perturbation, while older adults needed additional steps to regain balance. Young adults arrested center of mass movement by producing larger step widths than older adults following the support surface perturbation. 相似文献

We tested the effects of an observational intervention (Greer & Singer-Dudek, 2008) on establishing children's books as conditioned reinforcers using a delayed multiple baseline design. Three preschool students with mild language and developmental delays served as the participants. Prior to the intervention, books did not function as reinforcers for any of the participants. The observational intervention consisted of a situation in which the participant observed a confederate being presented with access to books contingent on correct responses and the participant received nothing for correct responses. After several sessions of this treatment, the previously neutral books acquired reinforcing properties for maintenance and acquisition responses for all three participants. 相似文献

The almost exclusive focus on punishment and inattention to compensatory alternatives in studies involving experimental games may yield patterns that do not accurately reflect how and when people respond to injustice, particularly if punishment and compensation are not psychologically equivalent approaches to justice restoration. In the current study, we examined participants' preference for punitive and compensatory actions, while also exploring emotional determinants and boundary conditions. Our results indicated that participants actually compensated victims more than they punished offenders and that the majority of participants assigned both. Furthermore, although both interventions were associated with emotional experiences of moral outrage toward the offender, self-focused emotions reflecting feelings of threat only predicted compensation and only when victims were aware that they had been victimized. These findings augment our understanding of third-party interventions, emphasizing the importance of considering response alternatives when studying the psychology of justice. 相似文献

The reaction to an unexpected balance disturbance is unpractised, often startling and frequently associated with falls. This everyday situation can be reproduced in an experimental setting by exposing standing humans to sudden, unexpected and controlled movements of a support surface. In this review, we focus on the responses to the very first balance perturbation, the so-called first trial reactions (FTRs). Detailed analysis of FTRs may have important implications, both for clinical practice (providing new insights into the pathophysiological mechanisms underlying accidental falls in real life) and for understanding human physiology (what triggers and mediates these FTRs, and what is the relation to startle responses?). Several aspects of the FTRs have become clear. FTRs are characterized by an exaggerated postural reaction, with large EMG responses and co-contracting muscles in multiple body segments. This balance reaction is associated with marked postural instability (greater body sway to the perturbation). When the same perturbation is repeated, the size of the postural response habituates and the instability disappears. Other issues about FTRs remain largely unresolved, and these are addressed here. First, the functional role of FTRs is discussed. It appears that FTRs produce primarily increased trunk flexion during the multi-segmental response to postural perturbations, thus producing instability. Second, we consider which sensory signals trigger and modulate FTRs, placing specific emphasis on the role of vestibular signals. Surprisingly, vestibular signals appear to have no triggering role, but vestibular loss leads to excessive upper body FTRs due to loss of the normal modulatory influence. Third, we address the question whether startle-like responses are contributing to FTRs triggered by proprioceptive signals. We explain why this issue is still unresolved, mainly because of methodological difficulties involved in separating FTRs from ‘pure’ startle responses. Fourth, we review new work about the influence of perturbation direction on FTRs. Recent work from our group shows that the largest FTRs are obtained for toe-up support surface rotations which perturb the COM in the posterior direction. This direction corresponds to the directional preponderance for falls seen both in the balance laboratory and in daily life. Finally, we briefly touch upon clinical diagnostic issues, addressing whether FTRs (as opposed to habituated responses) could provide a more ecologically valid perspective of postural instability in patients compared to healthy subjects. We conclude that FTRs are an important source of information about human balance performance, both in health and disease. Future studies should no longer discard FTRs, but routinely include these in their analyses. Particular emphasis should be placed on the link between FTRs and everyday balance performance (including falls), and on the possible role played by startle reactions in triggering or modulating FTRs. 相似文献

We examined the occurrence of faking on a rating situational judgment test (SJT) by comparing SJT scores and response styles of the same individuals across two naturally occurring situations. An SJT for medical school selection was administered twice to the same group of applicants (N = 317) under low‐stakes (T1) and high‐stakes (T2) circumstances. The SJT was scored using three different methods that were differentially affected by response tendencies. Applicants used significantly more extreme responding on T2 than T1. Faking (higher SJT score on T2) was only observed for scoring methods that controlled for response tendencies. Scoring methods that do not control for response tendencies introduce systematic error into the SJT score, which may lead to inaccurate conclusions about the existence of faking. 相似文献
