In γ-TiAl deformed at room temperature in single slip, prismatic loops ar often organized in a staircase-like configuration, called strings whose generation by cross-slip is facilitated by the dislocation tendency to form screw locks as described recently by Grégori and Veyssière. The present letter is aimed at showing that strings may be encountered in virtually any crystal provided that the two impinging dislocations exhibit significantly different velocities. The crossslip annihilation mechanism of crossed dislocations considered by Tetelman is revisited and shown to evolve into a configuration significantly distinct from that originally predicted. 相似文献

After receiving knowledge regarding some topic, people usually overestimate their prior topic knowledge. Two experiments investigated whether people would claim less prior knowledge if they worked to earn their present knowledge. In Study 1, students finishing a psychology course claimed less precourse psychology knowledge if they reported devoting more effort toward the course. In Study 2, the knew-it-all-along effect was stronger for participants who were simply given the answers to questions than for participants who studied for 20 minutes to learn the answers. Both cognitive and motivational factors can account for the observed effects of effort investment on retrospective knowledge judgments. 相似文献

The greater effect of negative than positive stimuli on judgments—the positive-negative asymmetry (PNA)—is rather pervasive. However, the effects of the valence of evaluations of the participant by the partner and attitude similarity between them on attraction have been inconsistent with PNA. The hypothesis that the weighting rule instigated by the first response interferes with the weighting rule normally expected for the second response was tested. As hypothesized, evaluations and attitude similarity interacted when attraction response was assessed prior to competence response but not when competence response was assessed first. The effects in the first measured response fully mediated the effects in the second measured response but not vice versa. Implications of the finding for attraction and PNA are discussed. 相似文献

AbstractLike the liberal nationalists, we insist that a sense of belonging together is necessary for the practice of an egalitarian democracy. Therefore, we can take a shared national identity as one of the building blocks of the welfare state. However, we argue that a shared cultural or civic national identity can not be a necessary condition for this sense of belonging together. The mere fact of co-operation and common participation in shared activities and projects can create a sense of belonging together, regardless of whether the participants do share a national identity. Governments of diversified societies can try to establish a shared national culture, but equally important is their task to create a sense of belonging together by virtue of co-operation and shared participation. It is particularly important that people can meet each other, and therefore efforts by the government to establish social mix and a common language may be legitimate policies. 相似文献

We examined the predictability of fathering self-efficacy and marital satisfaction on father involvement. The moderating effect of marital satisfaction on the relationship between father efficacy and father involvement was also explored. A cross-sectional survey was conducted using the convenience sampling method. A total of 2,029 valid questionnaires were collected from fathers with children aged 2–6 from 48 nurseries in Hong Kong. The fathers’ mean age is 39.1. 72.9 % of the fathers graduated from secondary school and 86 % had full-time jobs. Measures including self-efficacy subscale in the Parenting Sense of Competency Scale, the Index of Marital Satisfaction, the Inventory of Father Involvement were adopted in the present study. Hierarchical regression analyses showed that fathering self-efficacy and marital satisfaction were significant positive predictors of father involvement, whereas marital satisfaction moderated the effect of fathering self-efficacy on father involvement. It is thus important to improve martial satisfaction and enhance fathering self-efficacy for promoting father involvement. To gain a more comprehensive picture, future studies of father involvement may benefit by adopting a longitudinal research design, including the mothers and children as informants, and addressing other parenting correlates such as parenting stress and spousal support. 相似文献

This study examined the association among healthy and maladaptive aspects of interpersonal dependency and the management of pain in physical therapy outpatients. Ninety-eight patients were administered the Relationship Profile Test, West Haven-Yale Multidimensional Pain Inventory, and Pain Catastrophizing Scale. Results indicated that Destructive Overdependence was positively associated with an increased number of office visits, pain interference in one’s daily life, pain severity, affective distress, and receiving positive partner responses. Dysfunctional Detachment was associated with affective distress, pain interference in one’s daily life, and rumination about pain. Healthy Dependency was only associated with receiving distracting responses from others. Believing that a spouse/partner is supportive and caring about one’s pain partially mediated the relationship between overdependency and pain interfering in one’s life. These results support the clinical utility of assessing interpersonal dependency for its relationship to managing one’s pain and health care utilization. 相似文献

The literature on PTSD and metabolic disease risk factors has been limited by lacking investigation of the potential influence of commonly comorbid disorders and the role of race. In this study data were provided by a sample of 134 women (63 PTSD and 71 without PTSD). Separate sets of models examining associations of psychiatric disorder classifications with metabolic disease risk factors were used. Each model included race (African American or Caucasian), psychiatric disorder, and their interaction. There was an interaction of race and PTSD on body mass index, abdominal obesity, and triglycerides. While PTSD was not generally associated with deleterious health effects in African American participants, PTSD was related to worse metabolic disease risk factors in Caucasians. MDD was associated with metabolic disease risk factors, but there were no interactions with race. Results support the importance of race in the relationship between PTSD and metabolic disease risk factors. Future research would benefit from analysis of cultural factors to explain how race might influence metabolic disease risk factors in PTSD. 相似文献

This article examines the effectiveness of a newly introduced integrative structure and its impact on employee job perceptions in an aircraft maintenance organization. It is not common to find studies, that relate such changes to lower level employee reactions. The implementation of the change programme involved a system-wide approach incorporating both structural and cultural change. Using a retrospective methodology we assessed employee reactions to the changes introduced. We found that both intrinsic job satisfaction and job characteristics perceptions improved in the new integrative organization. The fact that positive findings have been identified when other studies found no relationship between such changes and attitudinal outcomes illustrates the efficacy of a system-wide approach to change. Extrinsic satisfaction and organizational commitment however did not improve. This can perhaps be explained by the fact that the latter areas are concerned with factors outside the direct completion of the job and may take much longer to change if indeed they can be shown to change over time at all. 相似文献

This study investigated relationships among religious participation, social support, and psychological distress within a sample of older adults while controlling for the influence of significant demographic variables. Community-dwelling older adults between the ages of 65 and 90 (n?=?115) completed a packet of instruments including the Negative Affect Scale of the PANAS, the Social Provisions Scale (SPS) and a tailored survey that included questions regarding religious participation and demographic variables. Correlational and multiple regression analyses were performed to determine predictors of negative affect. Results indicated that religious participation continued to predict negative affect with the effect of demographic variables statistically controlled for. Subjective social support was also found to moderate the relationship between religious participation and psychological distress. Religious participation appears to be more important regarding alleviating distress for those elderly low in social support compared with those high in social support. Religious participation may thus occupy an important position with regards to factors that manage psychological distress among elderly individuals, particularly for those low in social support. 相似文献

Positive effects of different dimensions of religiousness (including private, public and familial) on well-being as well as the stress buffering effects of religiousness have been documented. However, relatively little research has explored how these different facets of religiousness are related to psychological well-being in at-risk adolescents. This study examined family, public and private religiousness and their protective influence on psychological adjustment in adolescents at risk for poor psychological and behavioural outcomes. Participants include 186 urban teens divided between African Americans and European Americans. Structured interviews assessed religiousness, stress, as well as change in emotional distress and substance abuse problems over a one-year period. Greater private religiousness protects adolescents exposed to higher levels of stress from emotional and behavioural problems. In contrast, higher levels of family religiousness exacerbate emotional problems over time in adolescents exposed to greater stress. Findings demonstrate the complex influence of religiousness on psychological well-being in adolescence. 相似文献
