This study used a three-wave panel design (N = 119 complete cases for all waves) to test for social influence and selection in the relation of college students' heavy drinking and that of their social networks. Evidence emerged for both social influence and selection, leading the authors to probe more specialized issues related to each. Results regarding social influence revealed, further, that greater presence in the network of individuals that the focal respondent considered "drinking buddies" was predictive of one's own later drinking, controlling for potential confounds. Network demographic characteristics associated with a "risky" (i.e., heavy-drinking) network also were documented. An additional finding, important for selection, was that wave-to-wave change in average network drinking appeared to result primarily from network members with different drinking levels being added to and dropped from the network. Findings are discussed in the context of the recent renaissance in social-network research.  相似文献

The authors examined self-ratings and spouse ratings in a young adult newlywed sample across a 2-year interval. Rank-order stability correlations were consistently high and did not differ across the 2 types of ratings. As expected, self-ratings showed significant increases in conscientiousness and agreeableness--and declines in neuroticism/negative affectivity--over time. Spouse ratings yielded a very different pattern, however, showing significant decreases in conscientiousness, agreeableness, extraversion, and openness across the study interval. Spouse ratings also showed evidence of a "honeymoon effect," such that they tended to be more positive than self-ratings at Time 1. This effect had dissipated by the 2nd assessment; in fact, the spouse ratings tended to be more negative at Time 2. Analyses of individual-level change revealed little convergence between self- and spouse-rated change, using both raw change scores and reliable change index scores. Finally, correlational and regression analyses indicated that changes in spouse ratings were significantly associated with changes in marital satisfaction; in contrast, changes in self-ratings essentially were unrelated to marital satisfaction. These results highlight the value of collecting multimethod data in studies of adult personality development.  相似文献

The fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1994) groups disorders into diagnostic classes on the basis of the subjective criterion of "shared phenomenological features." There are now sufficient data to eliminate this rational system and replace it with an empirically based structure that reflects the actual similarities among disorders. The existing structural evidence establishes that the mood and anxiety disorders should be collapsed together into an overarching class of emotional disorders, which can be decomposed into 3 subclasses: the bipolar disorders (bipolar I, bipolar II, cyclothymia), the distress disorders (major depression, dysthymic disorder, generalized anxiety disorder, posttraumatic stress disorder), and the fear disorders (panic disorder, agoraphobia, social phobia, specific phobia). The optimal placement of other syndromes (e.g., obsessive-compulsive disorder) needs to be clarified in future research.  相似文献

Men who have a family history of breast and/or ovarian cancer may be offered a predictive genetic test to determine whether or not they carry the family specific BRCA1/2 mutation. Male carriers may be at increased risk of breast and prostate cancers. Relatively little is known about at-risk men’s decision-making about BRCA1/2 testing. This qualitative study explores the influences on male patients’ genetic test decisions. Twenty-nine in-depth interviews were undertaken with both carrier and noncarrier men and immediate family members (17 male patients, 8 female partners, and 4 adult children). These explored family members’ experiences of cancer and genetic testing, decision-making about testing, family support, communication of test results within the family, risk perception and risk management. Implicit influences on men’s testing decisions such as familial obligations are examined. The extent to which other family members—partners and adult children—were involved in testing decisions is also described. It is demonstrated that mothers of potential mutation carriers not only perceive themselves as having a right to be involved in making this decision, but also were perceived by their male partners as having a legitimate role to play in decision-making. There was evidence that (adult) children were excluded from the decision-making, and some expressed resentment about this. The implications of these findings for the practice of genetic counseling are discussed.  相似文献

Daily mobility behaviors, especially in cities with high traffic density, are among the most fundamental drivers of quality of life. Obligatory commuting necessitates individuals sacrificing their time, money, and geographic freedom to ensure their mobility. The personal cost of fatigue, stress, and environmental cost of carbon emissions is likewise substantial. The COVID-19 pandemic led to a widespread shift to telecommuting. The pandemic has permitted an unprecedented opportunity to study Millennials' attitudes towards commuting and telecommuting. A semi-structured interview method was used with Millennial (now the largest percentage of the workforce) white-collar (disproportionately able to do their work remotely) workers living in the megacity of Istanbul to understand how telecommuting has altered consumer commuting habits, values, preferences, and well-being. The results of this study show that Millennial white-collar workers in Istanbul see compulsory commuting as a waste of time, a stress factor, and an unwanted task. The shift towards telecommuting lowered the Millennials' tolerance for traffic and long commutes and reveals willingness for immobility at peak hours and appreciation of spatial independence as a lifestyle that increases quality of life. The need for understanding transport decisions has never been more pressing with the growth of megacities and the climate change crisis. This research has important implications for white-collar employees and their employers, as well as academics and public policy makers, who seek to understand mobility preferences and lifestyles of different generations and the environmental implications in a dynamic environment.  相似文献

Ratings of the importance of and satisfaction with 20 areas of the self were obtained from 3604 first or second year social science undergraduates from 14 countries (15 cultures). Factor analysis at the culture by gender level supported four factors for both sets of ratings. The resulting factor scores were analyzed for mean differences according to the cultural dimension of Individualism-Collectivism by Gender and by correlations with other cultural dimenions and economic indicators. It was found that participants from the 10 collectivist cultures placed greater salience for their self-concepts on “family values” than did those from the individualist cultures. However, this cultural difference was not found for “social relationships”. The expected gender differences, with females valuing “family values” and “social relationships” more highly, were found only for the individualist countries. The findings indicate that there may be a strong cultural level interaction effect between gender and Individualism-Collectivism on the nature of self-conceptions, and that the “family” and “social” aspects of self-concept in collectivist countries need to be considered separately.  相似文献

This study surveyed client satisfaction with an outpatient service in clinical psychology at a university-based clinic in New Zealand. In an effort to collect honest opinions rather than grateful testimonials from clients, special consideration was given to the methodology used. In the absence of guidelines on how to analyze client satisfaction data, a variety of techniques was developed. These methods and analyses are reviewed and recommendations made with regard to future use.  相似文献

Data from observations of 232 elementary classrooms and from student questionnaires were used to test a model linking teacher classroom practices to students' sense of the classroom as a community (assessed by questionnaire) through intermediate effects on students' classroom behavior. The model was generally confirmed and showed that teacher practices (emphasis on prosocial values, elicitation of student thinking and expression of ideas, encouragement of cooperation, warmth and supportiveness, andreduced use of extrinsic control) were related to student classroom behaviors (engagement, influence, andpositive behavior), which, in turn, were related to students'sense of community. Teachers' encouragement of cooperative activities appeared to be particularly important in this sequence. The appropriateness of the model was tested for schools serving populations that were both high and low in level of poverty, and all estimates of path coefficients were found to be invariant across these groups.

Cinematica is a minimal system for producing calibrated grayscale movies on an Apple Macintosh computer from within the Mathematica programming environment. It makes use of the ISR Video Attenuator and the VideoToolbox software library developed by Denis Pelli. By design, Cinematica provides a very low-level interface to the display routine. Display instructions take the form of a list of pairs (image index, colormap index). The philosophy is that programming is much easier in Mathematica than in C, so we reserve the complexity for Mathematica. A few simple examples are provided.  相似文献
