Despite the prevalence of goal setting in organizations, researchers have not thoroughly examined the implications of goal setting to work outcomes in interdependent work settings. A field survey (n= 442) assessed the relation of goal setting and goal sharing, the extent to which others are aware of an individual's work goal, to performance and conflict across varying levels of task interdependence. The results of moderated regression analyses demonstrate that in highly interdependent tasks, the use of goal setting resulted in lower performance levels. Moreover, goal setting and goal sharing in highly interdependent tasks resulted in individuals' reporting more somatic symptoms. The results are discussed in terms of clarifying the role of goal setting for interdependent tasks.  相似文献

This study investigated the relationships among social ties, task-related communication, and first industrial job performance of a group of young engineers by utilizing a cooperative (coop) engineering program as a natural study. The coop arrangement allowed the researcher to examine the work behavior of these young engineers with similar academic training who were working on comparable work assignments in the same set of organizations.The study found that the job performance of the coop engineers was related to the pattern of work- related communication but not the total number of contacts. Specifically, high performance new engineers were integrated more broadly into the interpersonal communication networks than low performance new engineers. Moreover, high performance new engineers exhibited communication patterns similar to those of high performance veteran engineers working on similar types of technical work. Social ties with the company staff was found to be related positively with job performance, but social ties with other coop engineers was found to be related negatively with job performance, a result which challenges an implicit assumption often made by researchers and managers about the organizational socialization of newcomers. Overall, this study provides an integrative framework for relating social ties and communication as key factors for understanding the job performance of young engineers and presents a methodology for assessing their organizational assimilation.  相似文献

The present study examines the level of work-nonwork conflict found in eight countries categorized by value dimensions of individualism/collectivism and masculinity/femininity. Results indicate that masculine/collectivist countries have the lowest level of work-nonwork conflict. In addition, it was found that in masculine/collectivist countries, the work role dominates over the nonwork role.  相似文献

Time series analysis of fertility can improve demographic forecasts. The optimal forecast and its variance for births to an age-structured population subject to serially correlated random fertility are developed. The general case in which the fertility process had arbitrary autoregressive structure is dealt with and then the 4 special cases of white noise, 1st-order autoregressive, 2nd-order autoregressive, and random walk are considered. Consequently, it is determined that the predictions and their variances are highly sensitive to the autoregressive structure of fertility and, therefore, if stochastic models are to be used for prediction, they must emphasize this aspect of the problem. Preliminary empirical efforts to model the time series of U.S. fertility from 1917 to 1972 proved unsuccessful, but it is obvious that at least a 2nd-order autoregressive scheme is require d. The analysis proveded should be helpful in: 1) any application of the procedures requires a successful parameterization of the fertility process; 2) fertility variations could be decomposed into the effects of nuptiality and marital fertility and then births and marriages could be jointly predicted; and 3) the simplifying approximations should be dropped and each age-specific rate could be analyzed and predicted.  相似文献

This study examined the association between physical domestic violence (PDV) and reported child maltreatment in a cohort of children at risk for maltreatment. Participants were 219 6- to 7-year-old children and their caregivers. PDV was measured by combining caregivers' self-reports and children's reports, while child maltreatment was based on state Division of Social Services Central Registry records. Among 219 child-caregiver pairs studied, 42 (19.2%) had at least one maltreatment report in the 2 years following the interviews. PDV consistently predicted child maltreatment, with adjusted odds ratios ranging from 2.96 to 3.46. In addition, we investigated interactions between PDV and other predictors of child maltreatment. Among Aid to Families with Dependent Children (AFDC) participants, PDV was highly associated with child maltreatment. However, this pattern was not observed among subjects who did not have AFDC. There is an increased incidence of child maltreatment reports in families experiencing PDV. AFDC participation intensified the probability of child maltreatment in the presence of PDV. Findings also suggest that in households experiencing PDV, social supports may protect children from maltreatment.  相似文献

This study examined the association between the therapeutic alliance in family therapy and changes in symptom distress, interpersonal relationships, and family coping. The participants (N = 81) were members of low socioeconomic status families referred to a university clinic for in-home family therapy. Participants completed the Outcome Questionnaire, Family Crisis Oriented Personal Evaluation, and the Family Therapy Alliance questionnaires. Regression analyses revealed that the therapeutic alliance explained 19% of the variance in symptom distress changes for mother, 55% for fathers, and 39% for adolescents. The implications of these findings for practicing and researching family therapy are presented.  相似文献

Self-harm behavior exhibited by adolescents with developmental disabilities can be the most challenging behavior for caregivers and health care professionals to address. Past interventions have taken a behavioral approach and focused on functional analysis to guide assessment and treatment. However, self-harm behavior is becoming more recognized as a means of communication. Therefore, it is important for health care professionals and caregivers to listen to adolescents' attempts to communicate and try to understand the meaning of the behavior. Early assessment is crucial to understanding the meaning of the behavior, and early intervention is necessary to prevent escalation or chronicity. Thorough assessment guides interventions and must be implemented in the context of clients' families and social world, and the broader community. Establishment of trusting relationships among adolescents, their families, and health care professionals is imperative. This article discusses self-harm behavior from a psychosocial perspective related to prevalence, onset, purpose, maintenance, and escalation. It also introduces a comprehensive framework to guide assessment and intervention.  相似文献

The authors examined changes in college students' illicit drug use, patterns of polydrug use, and the relationship between students' ages of initiation of substance use and later use of marijuana and other illicit drugs between 1993 and 2001. Data from 119 US colleges and universities in the Harvard School of Public Health College Alcohol Study were used in the study. They found significant increases in percentages of students' use of marijuana in the past 30 days (from 13% to 17%), past year (from 23% to 30%), and lifetime (from 41% to 47%) between 1993 and 2001, with most of the increase occurring between 1993 and 1997. Past 30-day use of other illicit drugs increased from 4% to 7% and past year use increased from 11% to 14%. More than 98% of marijuana and other illicit drug users used another substance. They also either smoked, were binge drinkers, and/or were users of another illicit drug. Drug prevention programs should emphasize heavy alcohol use and smoking and should start when students are in high school or earlier.  相似文献

Although there is research on training program evaluation, there is little systematic research on the design, development and use of training reaction evaluations. In order to obtain meaningful information from a program evaluation, evaluation professionals must be rigorous in the design and development of all aspects of an evaluation study, including instrumentation. The purposes of the study were to classify the dimensions of information sought using reaction evaluations and to establish design criteria for developing training reaction instruments. There were three major phases of the study: (1) classification of the dimensions and questionnaire design criteria used in reaction evaluations; (2) validation of the classified dimensions and the questionnaire design criteria by subject matter experts; and (3) assessment of a sample of training reaction instruments currently used in training programs in US corporations. The research findings were: eleven dimensions for reaction evaluation were identified and classified by purpose. Five overall design criteria, each consisting of several sub-criteria, were judged important in the design of reactionnaires. These include: introduction and directions; question format; question construction; questionnaire layout; and data analysis. It was concluded that a well-designed training reaction instrument integrates the proper application of design criteria with appropriate reaction dimensions. Most training reaction instruments used by US corporations consisted of questions representing only a few dimensions. The instruments varied in form and length. Few of them properly utilized the established questionnaire design criteria.  相似文献
