The developmental interplay between identity and adjustment was examined in a seven‐wave longitudinal study of 428 European female college students (Mage=18.8 years) over a period of 3 years, with semi‐annual measurement waves each year. Latent Class Growth Analysis (LCGA) was used to identify developmental typologies of both identity formation (i.e., dimensions of commitment and exploration) and adjustment (i.e., depressive symptoms and self‐esteem). Four trajectory classes emerged for identity, three of which had been suggested earlier in the literature ( Josselson, 1996 ): Pathmakers, Guardians, and Searchers. The fourth trajectory class was labeled Consolidators and consisted of individuals characterized by a strong focus on strengthening their current identity commitments, at the expense of a thorough exploration of alternative options. Three trajectory classes were identified for adjustment: Optimal Adjustment, Moderate Adjustment, and Stable Maladjustment. Each of the four identity trajectory classes was associated with a specific profile of adjustment, with the Searchers showing the poorest profile and the Pathmakers and Consolidators the most positive profile. Practical implications and suggestions for future research are outlined.  相似文献

With the knowledge that information and communication technology (ICT) has brought about significant changes in the structure and functioning of businesses, this research provides information about the changes that have occurred in ICT adoption in nonprofit organizations between 2000 and 2004. Using archival data, it specifically investigates various indicators of ICT adoption and adoption readiness factors. Results illustrate that nonprofit organizations are beginning to position themselves to take advantage of the opportunities provided by ICT adoption.  相似文献

A comprehensive multiple domain model (MDM) to understand condom use in adolescents was proposed and tested using structural equation modeling of data at three time points. The proposed model integrates social psychological theory, demographic and personality factors, social environment, and situational/contextual variables. Adolescents who were sexually active at time 2 (6 months after baseline) and time 3 (1 year after time 2) and completed surveys at all three time points were included in the analyses (N = 511). An iterative process of model testing resulted in a structural equation model that provided a good fit to the data (CFI = .92, RMSEA = .04). Models comparing gender and race as moderators also were calculated and supported the generalizability of the model. Results provide support for an MDM that goes beyond traditional social psychological models for a broader understanding of condom use in adolescents. Implications for further theory testing and safer sexual interventions are discussed.  相似文献

Theory-based, scientific research examining sexual behaviors of young adults is sparse in India, even though pre-marital sex among unmarried young people has been rising in recent years. At the same time, young people aged 15 to 24 are disproportionately affected by HIV/AIDS. This has been attributed in part to rising pre-marital sexual behaviors, coupled with a lack of sex education. The objective of this study was to advance an understanding of the determinants of sexual behavior among unmarried young adults in northern India. An adaptation of a comprehensive model of health behavior, the Multiple Domain Model, was employed to study the effects of environmental/cultural influences (parental and media), structural determinants (sex, socioeconomic status, age, caste, and place of residence), personality factors (sensation-seeking and impulsive decision making), gender role identity, psychosocial variables (attitudes, norms, and self-efficacy), contextual influences (relationship status and alcohol/drug use) and preparatory behaviors (frequency of being in sexual situations) on adolescents' sexual behaviors. Results of path analysis indicated that key predictors of ever having had vaginal sex included preparatory behaviors, masculine gender role identity, attitudes toward having sex and peer norms regarding sex. Implications of these findings for future research and intervention are discussed.  相似文献

Customer service is a key aspect of restaurant success, as performance has shown a reliable positive relationship with customer retention. However, waitstaff performance may deteriorate, as income from gratuities is often unrelated to service quality. The present study investigated the effectiveness of an intervention consisting of task clarification and task-specific feedback on restaurant service tasks and observed the relationship between task completion and gratuities. Three adult women servers participated during their regular working shifts at a local dine-in restaurant. Initially customer service task completion was low (36% on average across participants). Performance increased immediately following the introduction of the intervention, and all participants maintained 87.5%–100% task completion. Correlational analyses found that gratuities were unrelated to performance and may thus pose a problem for performance maintenance. Implications relating to feedback and payment schedules are discussed.  相似文献

In 2008, Marsan and Lengliné presented a nonparametric way to estimate the triggering function of a Hawkes process. Their method requires an iterative and computationally intensive procedure which ultimately produces only approximate maximum likelihood estimates (MLEs) whose asymptotic properties are poorly understood. Here, we note a mathematical curiosity that allows one to compute, directly and extremely rapidly, exact MLEs of the nonparametric triggering function. The method here requires that the number q of intervals on which the nonparametric estimate is sought equals the number n of observed points. The resulting estimates have very high variance but may be smoothed to form more stable estimates. The performance and computational efficiency of the proposed method is verified in two disparate, highly challenging simulation scenarios: first to estimate the triggering functions, with simulation-based 95% confidence bands, for earthquakes and their aftershocks in Loma Prieta, California, and second, to characterise triggering in confirmed cases of plague in the United States over the last century. In both cases, the proposed estimator can be used to describe the rate of contagion of the processes in detail, and the computational efficiency of the estimator facilitates the construction of simulation-based confidence intervals.  相似文献

In this article we address Emile Durkheim's theory that norms and values become more generalized and abstract in a society as it becomes more complex and differentiated. To test Durkheim's theory we examine etiquette manuals—the common texts that define normative manners and morals in American society. We perform a deductive content analysis on past and present etiquette manuals to understand what changes have occurred regarding shifting behavioral norms and values over time. Our findings suggest that a change has occurred in the presentation and language of contemporary etiquette manuals, reflecting a greater change in the normative order. We find—as Durkheim would expect—that three main shifts have occurred: a shift from specific to general expectations for behavior in social settings, a shift from demanding to more suggestive rules of behavior in social situations, and a weakening in the severity of sanctions for breaches of etiquette.  相似文献

Job attitudes and subjective well-being (SWB) have important relationships with one another. Moreover, job attitudes and, to an extent, SWB are related to chronological age. Owing to a ??graying?? workforce in industrialized countries, uncovering how age influences job attitudes is increasingly important. The present work explores the effects of cognitive-aging research on the item response process during attitude measurement. Research finds that older individuals attend selectively to positive affective experiences and weigh affective experiences more heavily during judgment than younger individuals. Based on cognitive-aging research, we propose an item-response process and hypothesize that chronological age results in a specific form of measurement non-equivalence. Our hypothesis is tested on 2 different samples of university employees, across 3 different job attitudes rooted in emotional experiences. Results indicate age-related measurement non-equivalence across all 3 attitudes such that older employees report more positive job attitudes than younger employees even when controlling for the latent attitude construct. Our findings suggest caution in interpreting of age-satisfaction correlations, focusing greater attention on understanding item response processes of older versus younger individuals and increased attention to job-related emotional experience for older employees.  相似文献

This 2½‐year, 5‐wave longitudinal study tests the hypothesis that acculturation discrepancies between Hispanic immigrant parents and adolescents would lead to compromised family functioning, which would then lead to problematic adolescent outcomes. Recent‐immigrant Hispanic parent–adolescent dyads (N = 302) completed measures of acculturation and family functioning. Adolescents completed measures of positive youth development, depressive symptoms, problem behavior, and substance use. Results indicated that Time 1 discrepancies in Hispanic culture retention, and linear trajectories in some of these discrepancies, negatively predicted adolescent positive youth development, and positively predicted adolescent depressive symptoms and binge drinking, indirectly through adolescent‐reported family functioning. The vast majority of effects were mediated rather than direct, supporting the acculturation discrepancy hypothesis. Implications for further research and intervention are discussed.  相似文献
