As the impact of breast cancer (BC) risk assessment in asymptomatic women with a family history of BC had never been explored in Italy, we performed a study on a retrospective series of women who had undergone BC risk assessment. To this aim, a semi-structured telephone interview was administered to 82 women. Most participants considered the information received as clear (96.2 %) and helpful (76.8 %). Thirty-eight (46.3 %) stated that their perceived risk of BC had changed after the counseling: for 40.2 % it had decreased, for 6.1 % increased; however, women highly overestimating their risk at the baseline (≥4-fold) failed to show improvements in risk perception accuracy. Sixty-six women (80.5 %) stated they had followed the recommended surveillance, while 19.5 % had not, mainly due to difficulties in arranging examinations. Most women (89.0 %) had shared the information with their relatives, with 57.3 % reporting other family members had undertaken the recommended surveillance. BC risk assessment was associated with high rates of satisfaction and had a favorable impact on risk perception in a subgroup of women. The impact on surveillance adhesion extended to relatives. Organized programs for identification and surveillance may help identify a larger fraction of at-risk women and overcome the reported difficulties in arranging surveillance.  相似文献

We propose that one’s subjective well-being (SWB) arises from the satisfaction of one’s basic needs, but that the importance of attaining specific needs will vary according to one’s gender, age, and national culture. We argue that the role of one’s national-cultural background in that process can best be unpackaged in terms of the emphasis of a nation’s citizens on the goals for socializing children, namely, self-directedness versus other-directedness and civility versus practicality. Accordingly, we analyzed the responses of 65,025 persons across 50 nations to questions on the World Values Survey about their perceived state of health, financial satisfaction, trust of in-group members, and sense of personal control over events. Using HLM analysis, we showed that all four factors were significant predictors of SWB pan-nationally, but that the linkages of financial satisfaction and trust of in-group members to SWB were moderated by a nation’s self-directedness and civility; those of financial satisfaction and health were moderated by age. These results indicate that the socialization emphases characterizing one’s national culture operate to make some of the key contributors to one’s SWB more or less predictive. Cross-national studies are thereby vindicated in their capacity to reveal nation-specific formulas for psychological processes leading to SWB.  相似文献

Abstract

Integrating renewable energy sources into the power grid and ensuring public interest in energy is a key concern in many countries. What role may art play, and what political strategies do artists employ, in order to intervene in the infrastructuring of energy and public environments? As the case study here, a Copenhagen art and energy competition invited artists and designers from around the world to submit ideas for large-scale public artworks that can generate utility-scale renewable energy. The competition process had a smooth and consensus-seeking political strategy, manifested in a set of tactical oscillations. In order to engage with local stakeholders and ensure the success of the competition, the project managers oscillated between presenting the competition as part of existing policy initiatives and as posing alternatives to existing policy. They oscillated between being situated in a pragmatic present and in an unprecedented future; between being tied to the specific site of the competition and belonging to no place in particular; and not least between being predominantly an art project and primarily an infrastructure project. Remarkable differences between cosmopolitics and smooth politics appear here, especially compared to the literature analysing the roles played by art and design when imagining new ways of living with energy. Oscillation between smooth politics and cosmopolitics may provide a generative way forward for actors wishing to engage in the infrastructuring of environments.  相似文献

Psychological capital is a positive psychological state that influences employees’ behaviors and attitudes. Research has only recently begun to examine the phenomenon as a shared psychological team state. The purpose of this research is to examine the mediating role of team psychological capital in the relationship between learning climate and outcomes at the individual and team levels. The findings, which were carried out among 82 school management teams, indicated a positive relationship between learning climate and the team’s psychological capital, and between the team’s psychological capital and the individual’s job satisfaction and the team’s organizational citizenship behavior (OCB). It was also found that team’s psychological capital mediates the relationship between the team’s learning climate and job satisfaction, and between learning mechanisms and the team’s OCB. The findings might encourage research into psychological capital as a team phenomenon and encourage decision-makers to develop ways of reinforcing psychological capital among teams.  相似文献

Three groups of adolescents who were 14 years old in 1974 were formed on the basis of peer nominations and teacher ratings in an ongoing longitudinal study: 1) reactively aggressive (REA) individuals who displayed reactive, that is, self-defensive aggression but not proactive aggression (43 boys, 35 girls); 2) proactively aggressive (PROA) individuals who attacked another person without a reason (56 boys, 35 girls); and 3) nonaggressive (NONA) individuals who were low in proactive and reactive aggression (48 boys, 45 girls). The groups were compared at ages 8, 14, and 27 in variables representing the constructs of a two-dimensional model of emotional and behavioral regulation. The REA Ss were characterized by higher self-control, especially constructiveness, at each age and better adult adjustment than the PROA Ss. The PROA males were prone to externalizing problems and criminality in adulthood, whereas the PROA females were prone to internalizing problems and neuroticism in adulthood. Both exhibited conduct problems in adolescence, and became heavy users of alcohol in adulthood. The PROA Ss had more children at age 27 than the other Ss. © 1996 Wiley-Liss, Inc.  相似文献

As social media becomes increasingly popular, human subjects researchers are able to use these platforms to locate, track, and communicate with study participants, thereby increasing participant retention and the generalizability and validity of research. The use of social media; however, raises novel ethical and regulatory issues that have received limited attention in the literature and federal regulations. We review research ethics and regulations and outline the implications for maintaining participant privacy, respecting participant autonomy, and promoting researcher transparency when using social media to locate and track participants. We offer a rubric that can be used in future studies to determine ethical and regulation-consistent use of social media platforms and illustrate the rubric using our study team’s experience with Facebook. We also offer recommendations for both researchers and institutional review boards that emphasize the importance of well-described procedures for social media use as part of informed consent.  相似文献
