The purpose of the study was to examine the antecedents and impacts of information technology (IT) adoption by small family-owned
businesses, using data from the National Family Business Survey. This research tested a model based on the Diffusion of Innovations
framework and the Technology Acceptance Model (TAM). Family business managers’ prior knowledge and level of IT use, business
location, and community size/type were important antecedents to the decision to adopt IT. Ease of use and decision to adopt
IT accounted for over 60% of the variance in usefulness of IT and implementation of internet and IT capabilities. The implementation
of IT capabilities accounted for nearly 40% of the variance in actual use of IT and perceived impact of the internet. 相似文献

This study assesses whether the influences of attitude towards deviance, exposure to delinquent peers and parental supervision
and encouragement on antisocial behavior are moderated by depressive symptoms. Two hundred and thirty eight African American
adolescents ages 13–19 from three public housing developments participated in this study. Results indicate that approximately
half of the youth did not engage in antisocial behaviors in the last year. Gender, depression, attitudes and peers were significant
correlates of antisocial behavior. Parental supervision and encouragement, and age were not related to antisocial behavior.
Interaction effects suggest that the relative influences of attitudes towards deviance and delinquent peers on antisocial
behaviors depend upon gender and level of depression symptoms. Implications for social work practice and future research are
discussed. 相似文献

In many domains, simple forms of classification rules are needed because of requirements such as ease of use. A particularly simple form splits each variable into just a few categories, assigns weights to the categories, sums the weights for a new object to be classified, and produces a classification by comparing the score with a threshold. Such instruments are often called scorecards. We describe a way to find the best partition of each variable using a simulated annealing strategy. We present theoretical and empirical comparisons of two such additive models, one based on weights of evidence and another based on logistic regression. 相似文献

Experiences in teaching internship courses illustrate some of the advantages of teaching sociological practice through community service. For example, a course requirement to spend 9 hours of each week of a semester in an advocacy group provides a richer variety of opportunities for students to learn about themselves, society, sociological theory, and research methodologies than is possible in conventional lecture–discussion classes. Furthermore, becoming participants in sociological interventions heightens students' awareness of related ethical concerns, as well as of the complexity of social problems, and of how to define viable individual and collective solutions. 相似文献

Abstract The aim of this study was to conduct a stress audit among construction industry site managers in the UK as a precursor to a stress management intervention programme. Qualitative data were obtained from in-dept interviews with a total of 36 male middle and senior construction site managers; and aquantitative data were obtained by questionnaire. Based on the analysis of 561 postal quenstionnaires, eight stressor factors were identified, most significantly, ambiguity (i.e. role and task). Job satisfaction levels were low compared to a normative population and influenced by grade level. Measures of mental health were similar to the norm for males, but both grade of management and type of contract affected mental health. Anxiety levels were signficantly high, independent of managerial grade. The stress of work overload and role insecurity (fear of failure) were associated with reduced mental health and high anxiety, and the stress of the organizational culture and climate was the strongest predictor of job dissatisfaction. There was some cause for concern for the vulnerable high-risk groups, i.e. the extreme type A and those working overtime. Medical data from a small subset of managers (n = 78) revealed that this group evidenced a better quality of psychological health than the group in total; but a high percentage of personnel had high levels of triglycerides and cholesterol. Recommendations for action focused on the needs of specific subgroups, and guided the organization on the acceptability of possible interventions at individual, interpersonal and organizational levels. 相似文献

The success of the Global Polio Eradication Initiative promises to bring large benefits, including sustained improvements in quality of life (i.e., cases of paralytic disease and deaths avoided) and costs saved from cessation of vaccination. Obtaining and maintaining these benefits requires that policymakers manage the transition from the current massive use of oral poliovirus vaccine (OPV) to a world without OPV and free of the risks of potential future reintroductions of live polioviruses. This article describes the analytical journey that began in 2001 with a retrospective case study on polio risk management and led to development of dynamic integrated risk, economic, and decision analysis tools to inform global policies for managing the risks of polio. This analytical journey has provided several key insights and lessons learned that will be useful to future analysts involved in similar complex decision-making processes. 相似文献

When inequities occur in the division of labor among adult siblings caring for older parents, conflict may result. This paper uses equity theory as a framework for understanding the processes used by siblings to rectify imbalances in their parental responsibilities. The study is based on a sample of 40 focus group participants who described caregiving relationships among siblings. Consistent with equity theory, these participants used two approaches to redress inequities in their sibling caregiving relationships: requesting behavioral changes from siblings and making cognitive changes. The findings suggest that these two approaches can result in more perceived equity but may also lead to even greater perceived inequity and distress. 相似文献
