问卷调查中的"问题"编排遵循一定的准则,主要是由易到难;由熟悉到陌生;先行为问题后态度问题;感兴趣的问题在前,有顾虑的问题在后;辅助性问题在前,敏感性问题在后;封闭式问题在前,开放式问题在后。  相似文献

为了实现对中国社工离职倾向现状的总体描述,并检验“个体—职业/组织—家庭三因素模型”对于解释中国社工离职倾向原因的科学性,采用“中国社会工作者职业现状调查”的大样本全国调查数据(n=3111)开展研究。结果发现,有19.6%的社工想离开社工行业,这表明中国社工离职(转行)倾向的现状不容乐观。分层回归分析发现,个体因素、职业/组织因素和家庭因素均可以独立地解释社工在离职倾向得分上的变异,这表明,“个体—职业/组织—家庭三因素模型”确实是一个解释中国社工离职倾向原因的合理框架。这一模型是对西方“个体—组织模型”的扩展,体现了在东方文化中家庭因素对社工离职倾向的重要影响。这一研究结果对社工机构如何降低社工的离职倾向提供了重要的启示。  相似文献

Despite the strategic importance of information technology (IT) to contemporary firms, chief information officers (CIO) often still have varying degrees of strategic decision‐making authority. In this study, we apply the theory of managerial discretion to define CIO strategic decision‐making authority and argue that the CIO's level of strategic decision‐making authority directly influences IT's contribution to organization performance. We also draw on the power and politics perspective in the strategic decision‐making literature to identify the direct antecedents to the CIO's strategic decision‐making authority. A theoretical model is presented and empirically tested using survey data collected from a cross‐industry sample of 174 matched pairs of CIOs and top business executives through structural equation modeling. The results suggest that organizational climate, organizational support for IT, the CIO's structural power, the CIO's level of strategic effectiveness, and a strong partnership between the CIO and top management team directly influence the CIO's level of strategic decision‐making authority within the organization. The results also suggest that the CIO's strategic decision‐making authority in the organization directly influences the contribution of IT to firm performance and that effective CIOs have a greater influence on IT's contribution when provided with strategic decision‐making authority.  相似文献

多重抽样框可以解决单一抽样框难以完整覆盖流动性目标总体的难题,连续性抽样调查则可以获取变量的时序观测数据,对总体现象进行追踪调查。本文将多重抽样框调查与连续性抽样调查两种方法结合在一起进行研究,深入分析基于多重抽样框的连续性抽样估计方法。文章首先设计了连续性调查环境下总体结构变动表;然后,在简单随机抽样假定下的轮换样本调查情形开展研究,设计了14种参数缩减方法对构建的似然函数进行估计求解,并给出了估计量的迭代计算过程;最后,对本文的研究内容进行了总结与展望。  相似文献

Developing a better understanding of the impact of uncertainty on process performance has been recognized as an important research opportunity in service design ( Hill, et al., 2002 ). Within this general research stream, our study focuses on the question of what managers can do to most effectively address operational uncertainty and mitigate its negative effects. To begin to address this question, we report on an exploratory study using a sample of professionals in the financial‐services industry who acted as informants on 108 financial‐services processes. These professionals were sampled from a population of graduates of a university in the northeastern region of the United States who were employed in the financial‐services industry. Based on these processes, we empirically examine the relationship between responses to operational uncertainty and process performance after controlling for customer mix, other uncertainty sources, and process type characteristics. Our findings suggest that process improvement—an uncertainty reduction approach related to the internal functioning of the process—as well as several uncertainty coping approaches are associated with better performing processes. However, uncertainty reduction approaches related to customer involvement with, and demands on, the process are not associated with better performing processes. We discuss the implications of our findings for determining what actions managers can take to reduce the negative performance effects of operational uncertainty and how managers can decide which of these actions to take. We conclude with a discussion of the limitations of our study.  相似文献

Mass customization has gained increasing importance in recent years due to its ability to provide customized products efficiently and effectively, and manufacturing companies are continuously searching for ways to develop their mass‐customization ability. Despite extensive literature focusing on mass customization, few studies have systematically examined the impact of work‐design practices on a company's mass‐customization ability. Using the Sociotechnical Systems theory as a foundation, we link work‐design practices with mass‐customization ability, specifically identifying ten work‐design practices and examining their impact on mass‐customization ability using survey data and empirical research methods. The results support our hypothesized links and suggest that work‐design practices that manage both the technical and the social dimensions for achieving organization success have significant impact on a company's ability to achieve mass customization.  相似文献

Organizations invest in technology with the expectation that it will contribute to performance, and members of the organization must use technology for it to make a contribution. For this reason, it is important for managers and designers to understand and predict system use. This paper develops a model of workstation use in a field setting where the use of the system is an integral part of the user's job. The model is based on the Technology Acceptance Model (TAM), which we extended to include social norms, user performance, and two control variables. Brokers and sales assistants in the privateclient group of a major investment bank provided data to test our extended model. The core perception variables in TAM do not predict use in this study. Social norms and one's job requirements are more important in predicting use than workers' perceptions about ease of use and usefulness. The paper discusses the implications of these findings and suggests directions for future research.  相似文献

In this paper, we present results from measuring physical disorder in Los Angeles neighborhoods. Disorder measures came from structured observations conducted by trained field interviewers. We examine inter-rater reliability of disorder measures in depth. We assess the effects of observation conditions on the reliability of reporting. Finally, we examine the relationships between disorder, other indicators of neighborhood status, and selected individual outcomes.Our results indicate that there is considerable variation in the level of agreement among independent observations across items, although overall agreement is moderate to high. Durable indicators of disorder provide the most reliable measures of neighborhood conditions. Circumstances of observation have statistically significant effects on the observers’ perceived level of disorder. Physical disorder is significantly related to other indicators of neighborhood status, and to children’s reading and behavior development.This result suggests a need for further research into the effects of neighborhood disorder on children.  相似文献

Migration and stratification are increasingly intertwined. One day soon it will be impossible to understand one without the other. Both focus on life chances. Stratification is about differential life chances - who gets what and why - and migration is about improving life chances - getting more of the good things of life. To examine the interconnections of migration and stratification, we address a mix of old and new questions, carrying out analyses newly enabled by a unique new data set on recent legal immigrants to the United States (the New Immigrant Survey). We look at immigrant processing and lost documents, depression due to the visa process, presentation of self, the race-ethnic composition of an immigrant cohort (made possible by the data for the first time since 1961), black immigration from Africa and the Americas, skin color diversity among couples formed by US citizen sponsors and immigrant spouses, and English fluency among children age 8-12 and their immigrant parents. We find, inter alia, that children of previously illegal parents are especially more likely to be fluent in English, that native-born US citizen women tend to marry darker, that immigrant applicants who go through the visa process while already in the United States are more likely to have their documents lost and to suffer visa depression, and that immigration, by introducing accomplished black immigrants from Africa (notably via the visa lottery), threatens to overturn racial and skin color associations with skill. Our analyses show the mutual embeddedness of migration and stratification in the unfolding of the immigrants’ and their children’s life chances and the impacts on the stratification structure of the United States.  相似文献
