This paper focuses on an argument that has been invoked in the stem cell debate: appeal to the Christian tradition. Bishop Richard Harries has put forward the claim that the Christian tradition offers precedent that would give ethical justification for experimenting on human embryos. In contrast, Pope John Paul II claimed that the tradition unwaveringly supported the protection of the human embryo from deliberate harm. In favour of Pope John Paul's reading of the Christian tradition is the fact that Christianity was notable from the outset for its wholehearted opposition to abortion. Bishop Harries can point to three elements in the tradition that seem to qualify the absolute prohibition on abortion: (1) variable penalties for abortion; (2) belief in delayed ensoulment; and (3) abortion to save the mother's life. Nevertheless, detailed consideration of the tradition shows that these apparent qualifications do not provide precedent for destructive experiments on human embryos. 相似文献

Intergenerational family relations are embedded in family cultures which influence how families regulate their relations over the whole life span with regard to key issues, such as autonomy and relatedness, or support exchange and reciprocity, and which may vary inter- and intraculturally. Migrant families undoubtedly face a special situation as values and expectations from the culture of origin and from the host cultural context might differ. Not much is known yet about how migrant families adapt their family cultures to the host cultural context. The present article will focus on aspects of intergenerational family regulation by taking into account family cultures of migrant compared to non-migrant families in a life span perspective. We will illustrate our theoretical outline by presenting first results from the IRMA-study comparing Luxembourgish and Portuguese immigrant families living in Luxembourg. We focus on issues of family cohesion, enmeshment and normative expectations regarding adult children’s support for their ageing parents, by drawing both on quantitative questionnaire as well as qualitative interview data. Implications for the experience of ambivalence and conflicts as well as well-being of family members from both generations will be discussed. 相似文献

Contextual cueing can be enhanced by reward. However, there is a debate if reward is associated with the repeated target–distractor configurations or with the repeated target locations that occur in both repeated and new displays. Based on neuroimaging evidence, we hypothesized that reward becomes associated with the target location only in new displays, but not in repeated displays, where the repeated target location is overshadowed by the more salient repeated target–distractor configuration. To test this hypothesis, we varied the reward value associated with the same target location in repeated and new displays. The results confirmed the overshadowing hypothesis in that search facilitation in repeated target–distractor configurations was modulated by the variable value associated with the target location. This effect was observed mainly in early learning. 相似文献

John Keown has constructed a logical slippery slope argument from voluntary euthanasia (VAE) to nonvoluntary euthanasia (NVAE). VAE if justified implies that death can be of overall benefit, in which case it should also be facilitated in those who cannot consent (NVAE). Hallvard Lillehammer asserts that Keown's argument rests on a fallacy. However, pace Lillehammer, it can be restated to escape this fallacy. Its validity is confirmed by applying to VAE some well-established general principles of medical decision making. Thus, either VAE and NVAE must be accepted together or, if NVAE is regarded as unacceptable, VAE should also be rejected. 相似文献

The role of dopamine (DA) in rewarding motivated actions is well established but its role in learning how to avoid aversive events is still controversial. Here we tested the role of D2-like DA receptors in the nucleus accumbens (NAc) and the dorsolateral striatum (DLS) of rats in the learning and performance of conditioned avoidance responses (CAR). Adult male Wistar rats received systemic, intra-NAc or intra-DLS (pre- or post-training) administration of a D2-like receptor agonist (quinpirole) or antagonist ((−)sulpiride) and were given two sessions in the two-way active avoidance task. The main effects observed were: (i) sulpiride and lower (likely pre-synaptic) doses of quinpirole decreased the number of CARs and increased the number of escape failures; (ii) higher doses of quinpirole (likely post-synaptic) increased inter-trial crossings and failures; (iii) pre-training administration of sulpiride decreased the number of CARs in both training and test sessions when infused into the NAc, but this effect was observed only in the test session when it was infused into the DLS; (iv) post-training administration of sulpiride decreased CARs in the test session when infused into the NAc but not DLS. These findings suggest that activation of D2 receptors in the NAc is critical for fast adaptation to responding to unconditioned and conditioned aversive stimuli while activation of these receptors in the DLS is needed for a slower learning of how to respond to the same stimuli based on previous experiences. 相似文献

The presence of peers increases risk taking among adolescents but not adults. We posited that the presence of peers may promote adolescent risk taking by sensitizing brain regions associated with the anticipation of potential rewards. Using fMRI, we measured brain activity in adolescents, young adults, and adults as they made decisions in a simulated driving task. Participants completed one task block while alone, and one block while their performance was observed by peers in an adjacent room. During peer observation blocks, adolescents selectively demonstrated greater activation in reward-related brain regions, including the ventral striatum and orbitofrontal cortex, and activity in these regions predicted subsequent risk taking. Brain areas associated with cognitive control were less strongly recruited by adolescents than adults, but activity in the cognitive control system did not vary with social context. Results suggest that the presence of peers increases adolescent risk taking by heightening sensitivity to the potential reward value of risky decisions. 相似文献

Financial constraints, mobility issues, medical conditions, crime in local areas can make cognitive assessment difficult for elders and telephone interviews can be a good alternative. This study was carried out to evaluate the reliability, validity and clinical utility of a Brazilian telephone version of the Mini Mental State Examination (Braztel-MMSE) in a community sample of healthy elderly participants and AD patients. The MMSE and the Braztel-MMSE were applied to 66 AD patients and 67 healthy elderly participants. The test-retest reliability was strong and significant (r = .92, p = .01), and the correlation between the Braztel-MMSE and the MMSE were significant (p = .01) and strong (r = .92). The general screening ability of the Braztel-MMSE was high (AUC = 0.982; CI95% = 0.964-1.001). This telephone version can therefore be used as a screening measure for dementia in older adults that need neuropsychological screening and cannot present for an evaluation. 相似文献

Academic dishonesty has been a frequent topic of research and discussion. In this article, we examine the differences between
student volunteers and student non-volunteers in terms of their attitudes towards academic dishonesty as well as their cheating
behaviors. We found that student volunteers held more serious attitudes towards cheating and academic dishonesty than did
student non-volunteers; however there were not many significant differences between student volunteers and student non-volunteers
when it came to cheating behaviors. We finally provide some suggestions for future research in the topic of academic dishonesty. 相似文献

Attachment patterns and personality dimensions have always been considered important to the development and adaptation of the individual. The first aim of this article was to address some basic questions about the place of attachment in a multimethod assessment when compiling a complete picture of the patient's personality functioning. The second aim was to present the Adult Attachment Projective Picture System (AAP; George & West, 2001) as a valid and productive assessment measure. Based on a single case study of an anorexic young woman, the article demonstrates how the AAP is integrated with the Rorschach Comprehensive System (Exner, 1991, 1993) and other assessment tools in both the assessment and in developing a treatment plan. 相似文献
