The promotion of organ donation requires a better understanding of the attributes associated with willingness to donate. This entails revealing complex interactions among personality attributes related to intentions and behaviors. In the present study, survey data from young adults (N = 367) were analyzed using decision tree algorithms to identify these interactions within the reasoned action framework. Within this structure, donation attitudes, intentions, and behaviors were examined in relation to individual differences such as conscientiousness, empathy, time orientation, religiosity, and interpersonal trust. 相似文献

ABSTRACTWe present results for the structural, electronic, vibrational, and electron-phonon coupling properties of LaSn3 and CaSn3 adopting the simple cubic AuCu3-type structure obtained using the the generalised gradient approximation of the density functional theory and plane wave ab initio pseudopotential method. Our electronic results show that both materials display metallic character with several bands, which have mainly Sn 5p character, crossing the Fermi level. The calculated phonon spectrum of LaSn3 accords very well with reported experimental measurements. The weights of the peaks in the Eliashberg spectral function of both compounds are enhanced with the use of experimental lattice constant in our electron-phonon calculation, increasing the value of average electron phonon coupling parameter from 0.876 to 0.937 for LaSn3 (by 7%) and from 0.642 to 0.725 for CaSn3 (by 13%). The use of experimental lattice constant also improves the agreement between theoretical and experimental values of the superconducting temperature for both compounds. 相似文献

We have fabricated a molecular organic light-emitting device comprising indium–tin oxide/a molecular organic layer/aluminum in which the organic layer is a green fluorescent protein. The device exhibits peak external quantum and power efficiencies of 8?±?0.2% and 13?±?0.7?lm?W???1 at a current of J?=?1.5?A?m?2, respectively. In addition, the turn-on voltage is 2.5?V for 1?cd?m?2 and the maximum luminance achieved is 1275?cd?m?2. This good performance can be explained by the presence of singlet-excited states, leading to a high internal efficiency. 相似文献

The present study examined the relationship between adolescents' attachment to parents and their feelings of alienation in the school context by considering the mediating role of adjustment and self-esteem. It was proposed that the degree of attachment to one's parents was associated with adjustment and self-esteem, which in turn predicted possible school alienation. A total of 227 students completed self-report measures on parental attachment, adjustment, self-esteem, and alienation from school. Results were consistent with the attachment theory and related literature that posits that (a) secure attachment to parents was associated with adjustment and self-esteem, (b) secure attachment to parents was negatively associated with feelings of school alienation, and (c) adjustment and self-esteem were a crucial mediators between attachment to parents and school alienation. In addition to enhanced adjustment, the self-esteem of adolescents may be an additional factor in reducing alienation at school. The results also supported the mediator role of self-esteem in the relationship between attachment to parents and adjustment. Finally, the relationship between self-esteem and school alienation were shown to be fully mediated by adjustment. The results were discussed in the context of responsibilities of teachers and school counselors, which may provide both students and parents with the skills to improve social functioning in the school context. 相似文献

Burnout and occupational participation among dentists with teaching responsibilities in universities
Meral Huri Nilsun Bağiş Onur Başibüyük Sedef Şahin Mutlu Umaroğlu 《Psychology, health & medicine》2017,22(6):693-700
The aim of this study was to investigate the levels of burnout and explore the relationships between burnout and occupational participation among dentists with teaching responsibilities. Canadian Occupational Performance Measure (COPM) was used to evaluate occupational participation with questions on demographic information among 155 dentists with teaching responsibilities. Age, gender, years of experience, academic position were the factors affecting level of burnout and occupational participation. Occupational performance score was negatively correlated with emotional exhausment (r = –.731) and depersonalization (r = –.693) while positively correlated with personal accomplishment (r = .611). Occupational satisfaction scores were negatively correlated with emotional exhausment (r = –.631) and depersonalization (r = –.625) while positively correlated with personal accomplishment (r = .614). Occupational participation level can effect burnout among dentists with teaching responsibilities. Further studies with a larger sample are needed to investigate these preliminary results deeply. 相似文献

We use interdependence theory and the inertia model to examine how gender and daily relational sacrifices predict daily variability in relationship commitment across a week in 43 U.S. couples who are unmarried cohabitors expecting their first child together (total of 455 days of data). We examined three variants of daily relational sacrifices: frequency, ease, and awareness for both individuals and partners, and we tested for gender differences. Using an Actor Partner Interdependence Model (APIM), we found that both women and men reported lower variability in commitment when men were perceived as highly aware of the sacrifices made for them. Additionally, women experienced lower variability in commitment when their male partners reported engaging in easier sacrifices. In contrast, women reported higher variability in commitment when they reported greater frequency of sacrifices for their partner. The results can be of practical use for practitioners working with expectant cohabitors and their partners given the unique role gender plays relative to how sacrifices shape variability in daily commitment. 相似文献

The major problem with the current emotional well-being scales is that they lack intentionality (being about something), which
makes them incongruent with the definition of subjective well-being. A new emotional well-being scale with new affect adjectives
has been developed by addressing intentionality. It focuses on individuals’ affective evaluations of their life and has showed
good psychometric quality. In the first and second studies, the factor structure of the scale, the Emotional Well-Being Scale,
was determined by exploratory and confirmatory factor analyses. Study 3 showed that the scores on the scale were stable in
time. The fourth and fifth studies indicated that this new construct did not overlap with personality dimensions of extraversion
and neuroticism, with impressive predictive and incremental validity estimates. 相似文献

Decades of empirical research have shown that friendship experiences are an essential predictor of happiness. However, what might account for the relationship between friendship and happiness? Two studies investigated perceived mattering (Marshall, J Adolesc 24:473–490, 2001) as a mediator of the association between friendship quality and happiness. Study 1 showed that perceived mattering to one’s best friend mediated the relationship between friendship and happiness. Study 2 replicated the findings of the first study and showed that mattering in friendships accounts for the role of friendship quality in happiness across the three closest friendships of the individual. The results are discussed in terms of the theoretical importance of understanding how friendship is related to happiness. 相似文献

This study sets out to investigate the changes in the perception of women in leading positions in communist and postcommunist Romania. The study uses a noninvasive paradigm of analyzing the content of obituaries for women and men in leading positions published in a national journal, and shows that the gender gap in management widened during the postcommunist period. In postcommunist Romania, women are perceived as being less able to lead/manage and more relational in their leadership style as compared to men, while in the communist period the gender differences were not significant. 相似文献
