Drawing from normal accident theory, high reliability theory, and systems theory, we analyze the Charter for the Protection of Children and Young People that is promulgated by the United States Conference of Catholic Bishops in response to the sexual abuses of minors by clergy members. Although the Charter is a step in the right direction, there remain some areas that require immediate attention. In spite of the goodwill processes, the safety of minors must remain the concerted efforts and responsibilities of individuals at all the various levels if the Catholic Church is to prevent further cases of abuse from happening.  相似文献

Although the health consequences of financial strain are well documented, less is understood about the health-protective role of social capital. Social capital refers to a sense of community embeddedness, which is in part reflected by group membership, civic participation, and perceptions of trust, cohesion, and engagement. We investigated whether perceptions of social capital moderate the relation between financial strain and health, both mental and physical. This longitudinal study surveyed adults in two communities in rural Ontario where significant job losses recently occurred. Data were collected on financial strain, social capital, perceived stress, symptoms of anxiety and depression, and physical health on three occasions over 18 months (N's = 355, 317, and 300). As expected, financial strain positively related to perceived stress, poor physical health and symptoms of anxiety and depression, whereas social capital related to less stress, better physical health, and fewer symptoms of anxiety and depression. Effects of financial strain on perceived stress and depressive symptoms were moderated by social capital such that financial strain related more closely to perceived stress and depressive symptoms when social capital was lower. The findings underscore the health-protective role of community associations among adults during difficult economic times.  相似文献

Low positive and high negative affect (NA) predict low rates of smoking abstinence among smokers making a quit attempt. Positive psychotherapy can both increase positive affect (PA) and decrease NA and, therefore, may be a useful adjunct to behavioral smoking counseling. The purpose of the present study was to assess the feasibility and acceptability of a positive psychotherapy for smoking cessation (PPT-S) intervention that integrates standard smoking cessation counseling with nicotine patch and a package of positive psychology interventions. We delivered PPT-S to 19 smokers who were low in PA at baseline. Rates of session attendance and satisfaction with treatment were high, and most participants reported using and benefiting from the positive psychology interventions. Almost one-third of the participants (31.6%) sustained smoking abstinence for six months after their quit date. Future studies to assess the relative efficacy of PPT-S compared to standard smoking cessation treatment are warranted.  相似文献

The current research examined subliminal priming of autobiographical memories. In Experiment 1 the subliminal primes consisted of affect-associated words (positive vs negative) and were presented just before the participants retrieved specific experiences to cue-words. The subliminal primes produced an inhibitory effect on autobiographical memory retrieval, with significantly lower positive ratings given to the emotional content of experiences retrieved after positive primes than given to experiences retrieved after negative primes. The subliminal primes for the second experiment consisted of words that related to specific lifetime periods (early childhood vs late childhood/early adulthood). A negative priming effect resulted again, with earlier life experiences retrieved after the presentation of late childhood/early adulthood primes. We believe the negative priming effects obtained in both experiments are consistent with predictions based on the self-memory system model of autobiographical memory. The results of this research may also explain mood-incongruent recall.  相似文献

It has been suggested that pain perception and attention are closely linked at both a neural and a behavioural level. If pain and attention are so linked, it is reasonable to speculate that those who vary in working memory capacity (WMC) should be affected by pain differently. This study compares the performance of individuals who differ in WMC as they perform processing and memory span tasks while under mild pain and not. While processing performance under mild pain does not interact with WMC, the ability to store information for later recall does. This suggests that pain operates much like an additional processing burden, and that the ability to overcome this physical sensation is related to differences in WMC.  相似文献

Case studies of memory-impaired individuals consistently show that reminiscing with SenseCam images enhances event recall. This exploratory study examined whether a similar benefit would occur for the consolidation of memories in memory-unimpaired people. We tested delayed recall for atypical actions observed on a lengthy walk. Participants used SenseCam, a diary, or no external memory aid while walking, followed by reminiscence with SenseCam images, diary entries, or no aid, either alone (self-reminiscence) or with the experimenter (social reminiscence). One week later, when tested without SenseCam images or diary entries, prior social reminiscence produced greater recall than self-reminiscence, but there were no differences between memory aid conditions for action free recall or action order recall. When methodological variables were controlled, there was no recall advantage for SenseCam reminiscence with memory-unimpaired participants. The case studies and present study differ in multiple ways, making direct comparisons problematic. SenseCam is a valuable aid to the memory impaired, but its mnemonic value for non-clinical populations remains to be determined.  相似文献

ABSTRACT

The Memory-for-Change framework proposes that retrieving episodic memories can facilitate new learning when changes between existing memories and new information are integrated during encoding and later recollected. Four experiments examined whether reminders could improve memory updating and enhance new learning. Participants studied two study lists of word pairs and were given a cued recall test on responses from both lists. Reminders of List 1 words pairs (A-B) appeared immediately before List 2 words pairs that included repeated cues and changed responses (A-D). Across experiments, we varied the types of reminders to determine whether differences in their effectiveness as retrieval cues would influence memory for the list membership of responses. We found that presenting intact reminders (cue-response) enhanced the memory benefits associated with recollection-based retrieval of changes relative to when no reminders appeared and when partial reminders (cue-only) appeared with and without feedback. Importantly, cue-response reminders benefitted memory when they were recognised in List 2 and when changes were later recollected. This suggests that integrative encoding can be facilitated when substantial environmental support is available to cue retrieval of existing memories. These findings have practical implications for understanding which reminders best aid the correction of memories for inaccurate information.  相似文献

Having trust in God is widely viewed as an essential component of many faith traditions (e.g., Christianity). Even so, researchers have paid relatively little attention to this core facet of religious life. The purpose of this study was to see if trust in God helps offset the effects of chronic economic problems on self-rated health, depressed affect, and life satisfaction. Data from a nationwide survey of middle-aged and older adults (N = 1,535) indicated that the effect of ongoing financial hardship on self-rated health, depressed affect scores, and life satisfaction was reduced for individuals who have greater trust in God.  相似文献

Many faith traditions emphasize the importance of adopting a range of virtues. Yet relatively few studies examine more than one virtue at a time. Moreover, researchers know relatively little about variations in the adoption of virtues, especially variations by race. The purpose of this study is to see if race differences emerge in 9 virtues: gratitude to God, humility, compassion for family and friends, compassion for strangers, providing emotional support to family and friends, providing tangible support to family and friends, providing emotional support to strangers, providing tangible support to strangers, and forgiving others. The data for this study come from a recent nationwide survey. Race differences were present in seven of the nine virtues, and in each instance the findings indicate that Blacks have higher virtue scores than Whites. The results further reveal that Blacks are likely to have higher virtue scores than Whites because they are more committed to their faith than Whites.  相似文献

Previous attempts to assess postmortem continuation beliefs have been hampered by unidimensional approaches and a lack of theory. We argue that core variations in postmortem beliefs can be described in terms of the fate of consciousness (awareness), identity (memory, personality), and physicality (the body) beyond the death event. Based on this theoretical framework, we constructed the Afterdeath Belief Scale, which measures five variations in belief: Annihilation, Disembodied Spirit, Spiritual Embodiment, Reincarnation, and Bodily Resurrection. We also assessed the extent to which people regard their beliefs and behaviors as efficacious in determining their fate beyond death. These new measures proved to be meaningfully related to self-reported religious affiliation, religiosity, spirituality, death concerns, mystical experience, and attitudes toward embodied existence. Implications for future research are discussed.  相似文献
