Happiness in the form of pleasant moods and emotions, well‐being, and positive attitudes has been attracting increasing attention throughout psychology research. The interest in happiness has also extended to workplace experiences. This paper reviews what is known about the definition, causes and consequences of happiness at work, drawing also on insights from the expanding positive psychology literature on happiness in general. Many discrete organizational behavior constructs arguably belong to a larger family of happiness‐related constructs, and share some common causes and consequences. Happiness at work includes, but is far more than, job satisfaction. A comprehensive measure of individual‐level happiness might include work engagement, job satisfaction, and affective organizational commitment. Aspects of happiness have been (and should be) conceptualized and measured at multiple levels, including transient experiences, stable person‐level attitudes, and collective attitudes, and with respect to multiple foci, such as discrete events, the job, and the organization. At all levels, there is evidence that happiness has important consequences for both individuals and organizations. Past research has tended to underestimate the importance of happiness at work.  相似文献

To examine the implications of fathers' occupational conditions (i.e., income, work hours, shift work, pressure, workplace racism, and underemployment) for family members' psychological adjustment, home interviews were conducted with fathers, mothers, and two adolescent offspring in each of 218 Mexican American families. Results underscored the importance of acculturation as a moderator. Fathers' income was negatively associated with depressive symptoms in highly acculturated families but not in less acculturated families. In contrast, fathers' reports of workplace racism were positively associated with depressive symptoms in less acculturated families but not in more acculturated family contexts. These findings were consistent across all 4 family members, suggesting that the "long arm" of the jobs held by Mexican American fathers extends to mothers and adolescent offspring.  相似文献

This article highlights the centrality of language in early childhood development and the potential for language delays to negatively affect long-term outcomes in educational and social domains. Given the high rate of language delays in the foster care population, an emphasis should be placed on assessing language skills among children ages 6 and younger entering foster care. The authors describe several existing approaches to assessing language skills and discuss obstacles to the widespread implementation of systematic evaluation among foster children. Finally, the authors discuss the need for research and programming to establish evidence-based practices that encourage the remediation of language delays in this highly vulnerable population.  相似文献

Speeding is a major contributor to motor vehicle accidents, which are the leading cause of death in adolescents. This study compares the extent to which adolescents with gambling behavior and substance use reported driving over the posted speed limits (“speeding”). Florida adolescents ages 13–17 (n = 1051) were surveyed, and asked about gambling activities, problems related to gambling, substance use, demographic questions, and speeding. Of the 562 respondents who were drivers, the gender distribution was 52.1% male and 47.9% female. Of those respondents, 76.9% were Caucasian, 6.8% were African American, 10.1% were Hispanic, and 6.1% were Native American/Asian/Other. Simple correlation analysis revealed that self-reported speeding is significantly related to gambling behavior and substance use. When a linear regression model was used, four factors showed the most significant influence on self-reported speeding: past year gambling tendency, age, trouble with the police due to drinking, and tranquilizer usage. Gambling behavior and high-risk speeding (driving ≥ 10 mph over speed limit) also were noted to be positively correlated. Our data indicate a relationship between risky driving, gambling, and other risk-taking behaviors in adolescents, and support the hypothesis that speeding may be a form of gambling behavior in this age group.  相似文献

We analyzed qualitative data gathered at a selective urban university with a large black student body. We found that black students from integrated backgrounds welcomed the chance to establish friendships with same-race peers even though they were at ease in white settings, whereas students from segregated backgrounds saw same-race peers as a source of comfort and refuge from a white world often perceived as hostile. These contrasting perceptions set up both groups for shock upon matriculation. Students from an integrated background were better prepared academically and socially, but were unfamiliar with urban black culture and uncomfortable interacting with students of lower class standing. Students from a segregated background were surprised to find they had little in common with more affluent students from integrated backgrounds. Although both groups were attracted to campus for the same reason??to interact with a critical mass of same-race peers??their contrasting expectations produced a letdown as the realities of intraracial diversity set in.  相似文献

This article tests the Fourier flexible form on quarterly U.S. monetary data. The data have been prescreened for consistency with the general axiom of revealed preference, and subindexes are formed using the Divisia approach. In this article, the global Fourier model fits well, although there is a potential problem of overfitting and certain data points exhibit behavior inconsistent with the model. The elasticities are variable over time, particularly around business-cycle troughs. It appears that financial asset demand surfaces are highly nonlinear and the many unsuccessful existing attempts to estimate money demand may not have worked well for this reason.  相似文献

A Sampling experiment performed using data collected for a large clinical trial shows that the discriminant function estimates of the logistic regression coefficients for discrete variables may be severely biased. The simulations show that the mixed variable location model coefficient estimates have bias which is of the same magnitude as the bias in the coefficient estimates obtained using conditional maximum likelihood estimates but require about one-tenth of the computer time.  相似文献

Abstract

Objective: To examine changes in diagnoses/treatment for 12 mental health (MH) conditions, previous use of campus MH services, and willingness to seek MH services in the future. Participants: ACHA–NCHA II participants from 2009 to 2015 (n?=?454,029). Methods: Hierarchical binary logistic regression with step 1 controlling for demographics and step 2 considering time. Results: Time was significant except for bipolar disorder, bulimia, and schizophrenia with increases for all conditions except substance abuse. Anxiety (OR?=?1.68), panic attacks (OR?=?1.61), and ADHD (OR?=?1.40) had the highest odd ratios. Use of MH services at current institution (OR?=?1.30) and willingness to utilize services in the future (OR?=?1.37) also increased over time. Conclusions: Based on a national sample, self-reported diagnoses/treatment of several MH conditions are increasing among college students. This examination of a variety of MH issues can aid college health professionals to engage institutional stakeholders regarding the resources needed to support college students’ MH.  相似文献

This study investigated the influence of social context (mothers, fathers, best friends, medium friends) and type of negative affect (anger, sadness, pain) on 66 second-grade and 71 fifth-grade children's goals and strategies for affect regulation. Hypothetical vignette methodology was used. Results indicated that children perceived parents to be more accepting of emotional expressivity than peers. Children endorsed instrumental, prosocial, and rule-oriented goals and verbal regulation strategies more for anger and sadness than pain. Girls endorsed affective more than aggressive strategies, whereas the opposite pattern held for boys. Older children endorsed more regulation strategies than younger children.  相似文献
