The actions of organizational leaders are important determinants of the emergence, management, and consequences of employee emotional experience. However, the nature and dimensionality of leader emotion management and the behaviors that constitute such management are largely unknown. The authors present a comprehensive, theoretically-derived model of leader emotion management which clarifies the nature of emotion management and its role in leadership. This model also delineates the knowledge and skill-based antecedents of emotion management and the consequences of such management. Specifically, we propose linkages between particular KSAOs and specific emotion management dimensions and between those dimensions and particular individual and organizational outcomes. The model is meant to serve as a framework to guide empirical efforts in investigating the nature and correlates of leader emotion management.  相似文献

Even though widespread efforts have focused on educating young adults about HIV and AIDS, many individuals continue to engage in behaviors that place them at risk. These behaviors include frequent experimentation with alcohol and other drugs prior to sex, engaging in sexual activity with different partners, and inconsistent safe sex practices (Butcher et al. 1991). The combination of these risky behaviors causes increased concern about the spread of HIV among those of college age. This study focused on two behaviors by examining the relationship between substance use during adolescence and early initiation of sexual activity in a sample of 950 subjects aged 19–21 in a mid-sized southern city. Results indicate that early use of alcohol and marijuana relates to earlier initiation of sexual activity and subsequent risky sexual behavior among young adults. Also, gender differences were observed for frequent users of marijuana and alcohol with males engaging in riskier sexual practices. Recommendations for interventions are made.  相似文献

Using a new analytic approach, construct validity estimates are developed for proposed social indicators of self-reported well-being. Two separate investigations are reported: the first involves data on six aspects of well-being each assessed by six methods from 222 adults in one geographic area; the second, a partial replication and extension, involves a more limited set of indicators measured on a sample of 1297 respondents representative of all American adults. The results provide evidence that perceptions of well-being can be measured by single questionnaire or interview items using any of four formats with validities in the range of 0.7 to 0.8 and with correlated method effects contributing less than 10% of the total variance. Two other formats, however, were markedly less valid. These findings are important in view of past criticisms of ‘subjective’ social indicators as lacking in validity, and the findings can guide current efforts to develop new ways to assess the quality of life. Methodologically, the article illustrates the feasibility and utility of deriving parameter estimates of structural equation models of multimethod-multitrait data using Joreskog's LISREL algorithm. The possibility of deriving validity estimates in this way, even when the data include correlated errors, opens new and important opportunities to precisely assess the amount of error variance in much social science data.  相似文献

Parenthood postponement is a key demographic trend of the last three decades. In order to rationalize that stylized fact, we extend the canonical model by Barro and Becker (Econometrica 57:481–501, 1989) to include two—instead of one—reproduction periods. We examine how the cost structure of early and late children in terms of time and goods affects the optimal fertility timing. Then, we identify conditions that guarantee the existence and uniqueness of a stationary equilibrium with a stationary cohort size. Finally, we examine how the model can rationalize the observed postponement of births, and we highlight two plausible causes: (1) a general rise in the cost of children in terms of goods and (2) a decline in the degree of family altruism.  相似文献

Healing from childhood sexual abuse: a theoretical model   总被引:1,自引:1,他引:0  
Childhood sexual abuse is a prevalent social and health care problem. The processes by which individuals heal from childhood sexual abuse are not clearly understood. The purpose of this study was to develop a theoretical model to describe how adults heal from childhood sexual abuse. Community recruitment for an ongoing broader project on sexual violence throughout the lifespan, referred to as the Sexual Violence Study, yielded a subsample of 48 women and 47 men who had experienced childhood sexual abuse. During semistructured, open-ended interviews, they were asked to describe their experiences with healing from childhood sexual abuse and other victimization throughout their lives. Constructivist grounded theory methods were used with these data to develop constructs and hypotheses about healing. For the Sexual Violence Study, frameworks were developed to describe the participants' life patterns, parenting experiences, disclosures about sexual violence, spirituality, and altruism. Several analytic techniques were used to synthesize the findings of these frameworks to develop an overarching theoretical model that describes healing from childhood sexual abuse. The model includes four stages of healing, five domains of functioning, and six enabling factors that facilitate movement from one stage to the next. The findings indicate that healing is a complex and dynamic trajectory. The model can be used to alert clinicians to a variety of processes and enabling factors that facilitate healing in several domains and to guide discussions on important issues related to healing from childhood sexual abuse.  相似文献

Recent epidemiological evidence suggests that even in the midst of the “terrible twos,” frequent/severe oppositional‐defiant behaviors (ODBs) are not common among toddlers and hence may be indicative of a significant opposition‐defiance problem. The main objective of this study was to obtain a maximum likelihood estimate of the proportion of toddlers in the general population who are reported to exhibit ODBs on a frequent basis, and to test for gender differences therein. Data came from The Québec Longitudinal Study of Child Development, a survey of a representative birth cohort of children from the Canadian province of Québec. Multigroup latent class analysis was used to distinguish between toddlers who exhibit ODBs on a frequent basis and those who do so only occasionally or not at all. The results show that 12.4% of 17‐month‐old boys and girls exhibit ODBs on a frequent basis. Further, the results show a strong positive association between opposition‐defiance and physical aggression early in life, with a great majority of physically aggressive toddlers exhibiting ODBs on a frequent basis. In contrast, the results show that only a minority of toddlers who may be experiencing a significant opposition‐defiance problem exhibit physically aggressive behaviors on a frequent basis.  相似文献

The literature shows that there are many problems with enterprise document search. Studies reveal that typical knowledge workers spend between 10% and 20% of their time searching for documents they never find. While many argue that metadata can improve enterprise document search, in reality few organizations use metadata. This represents a missed opportunity. This article describes the results of two experiments that use simulation to evaluate the actual impact of metadata on the costs and benefits of enterprise search. The first study provides quantitative evidence of the increase in recall and precision that stems from the use of metadata‐enhanced document searches. The second study demonstrates that simple metadata structures can be nearly as effective as complex ones, implying that the cost of creating and maintaining metadata is likely to be lower than generally thought. This is the first study to provide explicit quantitative evidence of the gains that can be achieved from the use of metadata, and one of only a handful of studies that examines the cost of creating and maintaining metadata.  相似文献

Defined as a set of distinct processes that included the declining use of large psychiatric institutions and the increasing use of outpatient services and general hospitals, deinstitutionalization occurred earlier in Saskatchewan than other provinces in Canada. It was led by a CCF government dedicated to major change across a number of sectors including mental health, assisted by one of the most influential and well-organized social movement organizations of the 1950s, the Saskatchewan Division of the Canadian Mental Health Association (SCMHA). However, by the late 1950s and early 1960s, the SCMHA opposed the CCF government's policy priority on medicare which it felt came at the expense of mental health care, in particular the implementation of a regional psychiatric hospital system called the Saskatchewan Plan. As a consequence, the SCMHA, once such a powerful ally of the CCF government in health reform, formed a strategic and temporary coalition with the anti-medicare forces in the province. Given the fact that a number of medical staff within the government's department of public health were prominent members of the SCMHA, the CCF government found that it occupied an increasingly divided house at the very time it was struggling to introduce medicare in the midst of civil unrest and a doctors' strike.  相似文献

Feeling at Risk Matters: Water Managers and the Decision to Use Forecasts   总被引:1,自引:0,他引:1  
Experts contend that weather and climate forecasts could have an important role in risk management strategies for community water systems. Yet, most water managers make minimal use of these forecasts. This research explores the determinants of the use of weather and climate forecasts by surveying managers of community water systems in two eastern American states (South Carolina and the Susquehanna River Basin of Pennsylvania). Assessments of the reliability of weather and climate forecasts are not driving their use as water managers who find forecasts reliable are no more likely to use them than are managers who find them unreliable. Although larger systems and those depending on surface water are more likely to use forecasts for some (but not all) purposes, the strongest determinant of forecast use is risk perceptions. Water managers who expect to face problems from weather events in the next decade are much more likely to use forecasts than are water managers who expect few problems. Their expectations of future problems are closely linked with past experience: water managers who have had problems with specific types of weather events (e.g., flood emergencies) in the last 5 years are likely to expect to experience problems in the next decade. Feeling at risk, regardless of the specific source of that weather-related risk, stimulates a decision to use weather and climate forecasts.  相似文献
