AbstractUsing human embryos in research remains a controversial issue, especially in Christian bioethics. Although the official Catholic stance rejects human embryonic stem cell research, Christian thinkers T. Peters, K. Lebacqz and G. Bennett support it. They endorse the 14-day Rule and argue that ex vivo embryos lack moral worth. I examine and challenge the 14-day Rule and location argument (in vivo/ex vivo). I develop a theory of holistic anthropology and intrinsic moral value for human embryos. I conclude that intrinsic moral value is not equal to full moral value, and therefore use of embryos in biomedical research is morally permissible. 相似文献

Delay of gratification in young children has been linked to long-term behavioral and academic outcomes. This study explored parent behavior during a laboratory paradigm as possible associates of delay ability. The sample consisted of 50 two- and three-year-old children and their primary caregivers. A newly created laboratory task, the gift delay task, was conducted to assess delay of gratification. Additionally, parents completed a child temperament (EASI-III) questionnaire. Based on the award-oriented behavior in the gift delay task, children were classified into three groups: delay (20 %), touch and go (i.e., approached the gift, but demonstrated some delay ability; 46 %), and non delay (34 %). Likewise, parents were classified into three groups: non-directive (parents did not initiate any interactions, but may have participated in child-led activity), active (parents initiated interaction with the child no more than 3 times), and very active (parents initiated 4 or more interactions with the child). Significant differences in emotionality and impulsivity were found between the 3 groups of children; additionally, significant differences in delay ability were found based on parent classifications suggesting that there is an optimal level of involvement on part of the parent that helps the child to wait, but beyond this point, involvement may be detrimental to a successful delay outcome. Implications for behavioral interventions focused on parental support and scaffolding are discussed. 相似文献

Research investigations into employee well-being (EWB) have tended to take a between-individual approach, which highlights differences among people. This traditional paradigm has been complemented by examinations of intraindividual EWB, which explores within-person variation over periods of time. Drawing on affective events theory (AET), we further elaborate the implications of intraindividual EWB for two reasonably stable sets of constructs—personality traits and affective climates. We argue that the intraindividual paradigm challenges scholars to rethink what they mean by stability, concluding that stability can be conceptualized in two ways—as reasonably consistent levels of affect and predictable patterns of affective change. 相似文献

Fifty‐eight outpatients with major depression completed the NEO Personality Inventory at intake (time 1) and after up to three months of anti‐depressant treatment (time 2). Within this group, 26 patients met additional Research Diagnostic Criteria for chronic minor depression. Repeated‐measures analyses revealed significant decreases in Neuroticism scores, and significant increases in Extraversion and Conscientiousness scores, from time 1 to time 2 for both patient groups. In addition, despite similar symptom severity at time 2, the patients with major depression+chronic minor depression scored significantly higher on the Angry Hostility facet of Neuroticism and significantly lower on Agreeableness than those with major depression alone. We suggest from these findings that Angry Hostility and low Agreeableness may represent a trait vulnerability in individuals with chronic minor depression that persists even following remission of the major depressive state, and that this may help to explain their high rates of relapse and recurrence.

The persistent and unresolved issue of minority disproportionality in special education provides a strong rationale for ensuring that assessment is culturally appropriate and sensitive. An extensive literature on test bias has failed to find evidence of bias sufficient to fully explain disproportional representation of minorities in special education. Yet minorities in this nation, most especially African Americans, have been exposed to a long history of unequal opportunity and oppression, and these inequities continue to be played out in educational settings. In the face of inadequate cultural and educational opportunity, unbiased tests provide an accurate estimate not only of individual capability, but also of the inhospitable conditions that depress that capability. A failure to take differential educational opportunity into account when considering minority test performance may lead to serious errors of test score interpretation. In the face of unequal educational opportunity, culturally competent assessment thus means more than manipulating the content of tests. Rather, it represents a comprehensive process that uses the results of assessment to identify and remedy educational conditions that systematically disadvantage students of color. 相似文献
