Mexican American youth often engage in relatively high levels of prosocial behaviors. We theorize that this may be due to a cultural value system that encourages familism values, which, in turn, may foster the development of sociocognitive processes that promote prosocial behaviors. Two hundred and five Mexican American early adolescent youth (Mage = 10.9 years, SD = 0.84; 51% girls) reported their familism values, perspective taking, prosocial moral reasoning, and six types of prosocial behaviors. The results indicated that perspective taking partially mediated the relation between familism values and the specific prosocial tendencies theoretically linked to the Mexican American culture. The study demonstrated the utility of integrating cultural and traditional developmental mechanisms in attempting to explain prosocial behaviors.  相似文献

The prevalence of casual sexual activity among teens and emerging adults has led to much public attention. Yet limited research has investigated whether the number of casual sexual partners per year changes as heterosexual men and women transition from adolescence into emerging adulthood. We considered the influence of social context and life course factors on the number of casual sex partners. We examined four waves of interviews from the Toledo Adolescent Relationships Study (TARS) and used negative binomial growth curve models to investigate patterns of change in the number of casual sex partners (N = 1,196) ages 15 to 22. Men and women both reported increases in the number of casual sex partners over time and did not differ from each other in the rate of change over time. In all, 40% of respondents reported a recent casual sex partner at age 22. Number of prior dating relationships, education status, substance use, and perceptions of peer sexual behavior significantly influenced the number of casual sex partners. Emerging adults who did not complete high school, compared to those enrolled in four-year degree programs, reported significantly more partners. The findings contribute to research on intimate relationships and provide insights for programs targeting emerging adults.  相似文献

We studied young adolescents' seeking out support to understand conflict with their co‐resident fathers/stepfathers, and the cognitive and affective implications of such support‐seeking, phenomena we call guided cognitive reframing. Our sample included 392 adolescents (Mage = 12.5, 52.3% female) who were either of Mexican or European ancestry and lived with their biological mothers and either a stepfather or a biological father. More frequent reframing was associated with more adaptive cognitive explanations for father/stepfather behavior. Cognitions explained the link between seeking out and feelings about the father/stepfather and self. Feelings about the self were more strongly linked to depressive symptoms than cognitions. We discuss the implications for future research on social support, coping, guided cognitive reframing, and father–child relationships.  相似文献

Multi-state models (MSMs) are useful to analyze survival data when, besides the event of main interest, one or more intermediate states of the individual are identified. These models take the several existing states and the possible transitions among them into account. At the same time, covariate effects on each transition intensity may be investigated separately and, therefore, MSMs are more flexible than the standard Cox proportional hazards model. In this work, we use MSMs to investigate the impact of the quality of a transplanted kidney for a group of patients at the Hospital Universitario Central de Asturias. Specifically, we use an illness-death model to study the evolution of patients with kidney disease who received a renal transplant after a dialysis period. The intermediate state is defined as the failure of the received organ, while the terminating state is the death of the patient. In order to increase the potential number of organs available for transplant, the standards of quality for the transplanted kidneys were relaxed (the new criteria are labeled expanded criteria), and these ‘expanded kidneys’ were transplanted in appropriate candidates (older patients, with higher prevalence of diabetes mellitus). Results suggest that the expanded kidneys have a minor effect on survival, while both the kidney mortality and the risk of death increase with the patient's age and the serum creatinine and serum hemoglobin levels.  相似文献

The relationship between class and voting choices has been the subject of controversy in recent years, especially in connection with the apparent decline of the traditional left. This paper examines class voting in Australia, focusing on three major issues: (1) changes in the overall strength of class voting (2) realignment, or changes in the relative political positions of the classes (3) the connection between the strength of class voting and support for Labor. It finds that (1) there is a decline in 'general' class voting (2) much of this decline involves a realignment of certain middle class groups, but there is no support for the popular idea that class alignments have become more complex (3) there is no connection between the strength of class voting and Labor performance. Our results cast doubt on accounts that regard the electoral difficulties of left parties as a symptom of the decline of class.  相似文献

This study reports on the preliminary development and validation of the Social and Emotional Health Survey (SEHS) with a sample of 4,189 (51 % female) California students in Grades 8, 10, and 12. The SEHS was designed to measure the psychological building blocks of adolescents’ positive mental health and is operationalized in the present study by a theoretical model comprised of 12 measured indicators that form four first-order domains (belief-in-self, belief-in-others, emotional competence, and engaged living) that, in turn, contribute to one underlying, second-order meta-construct called covitality. This study was the first to investigate the validity and utility of the adolescent covitality construct, which is conceptualized as the synergistic effect of positive mental health resulting from the interplay among multiple positive-psychological building blocks. Findings from confirmatory factor analyses, invariance analysis, and latent means testing all supported the theoretical model underlying the SEHS, indicating that the second-order covitality model was the best fit for both males and females. Results from a path-modeling analysis indicated that covitality was a strong predictor of students’ subjective well-being (operationalized as a composite of life satisfaction, positive affect, and negative affect), and findings from additional concurrent validity analyses indicated that adolescents’ covitality level was significantly associated with self-reported academic achievement, perceptions of school safety, substance use, and experiences of depressive symptoms. Implications for theory, practice, and future research are discussed.  相似文献

Abstract

In February 1946, the 20,000 sailors of the Royal Indian Navy, the colonial navy of the Government of India, mutinied. Having a number of grievances, from colonial rule of India, inefficient demobilisation procedures and ill treatment from superior officers, sailors on ships and shore establishments across the Indian Ocean took part in the mutiny, which represented the largest time a military force had disobeyed British Rule since the Mutiny of 1857. This paper examines the ways in which the geographies and mobilities of naval service shaped the political lives of the sailors in the RIN. On the one hand, both military (naval) and colonial forms of discipline worked through the spaces of the ship to attempt to control and order sailors’ lives. On the other, the mobile nature of life at sea, travelling from place to place and encountering colonial difference within the RIN, opened the door to different political ideas to influencing the sailors. At the same time, far from being a disconnected space, separate from the land, the naval ship combined with sailors’ land-based connections allowed them to contest and rework ‘landed’ political activity from the sea.  相似文献
