建设海峡西岸社会主义新农村的战略定位

从把握中央精神实质、反思国内外农村发展经验和融入海峡西岸经济区建设全局等3个方面分析探讨了海峡西岸社会主义新农村建设的战略定位问题。认为,准确定位要根据中央的精神实质,把握好世界现代化发展过程城乡演变的基本规律和我国城乡发展的特殊性、全国的共性和海峡西岸经济区的特点及其建设全局和新农村建设的关系,从海峡西岸经济区建设全局和持续发展的高度处理好新农村建设与加快工业化和城镇化发展的矛盾,加大外力推动促进内源发展,建立新型的城乡关系,促进农村经济与社会的综合发展,增进农民福祉。     

建设海峡西岸社会主义新农村的价值选择

建设社会主义新农村,本质是要缩小城乡差距,使农村在加速工业化、城市化的过程中能够与城市共同协调发展,使农民与城市居民一样享受等值不同质的现代生活。以等值不同质为取向增进农民福祉,是海峡西岸社会主义新农村建设的出发点和落脚点。建设海峡西岸社会主义新农村,要树立大资源观,以增量资源为杠杆激活存量资源,构建平等、互动、共福的新型城乡关系。     

Exploring social constructions of followership: A qualitative study

This study adopts a qualitative approach to deconstruct the meaning of followership. Interviews were conducted with employees in various industries to examine how individuals socially construct their roles as followers and to explore followership schemas and contextual influences that relate to these constructions. Results suggest that while some individuals socially construct definitions around passivity, deference and obedience, others emphasize the importance of constructively questioning and challenging their leaders. With regard to personal qualities that are thought to make followers effective, major themes such as obedience, expressing opinions, and taking initiative were found to be most disparate across different groups of followers. Results also revealed that contextual factors may affect both followership constructions and behavior in the follower role. These findings have important implications regarding a need to examine the construct of followership in leadership research, as well as raise interesting possibilities for advancing an “expanded” view of leadership in organizations.     

Operationalizing the Construct of Friendship among Children: A Psychometric Comparison of Sociometric-Based Definitional Methodologies

Peer relations researchers generally agree that friendship involves a close, mutual, dyadic relationship. However, the lack of consensus on how to operationalize this construct has limited our understanding of the role of friendship in social adjustment. The present study directly compared the psychometric properties (i.e., number of friendships identified, concordances, and stability) of the five major different definitions of friendship used in the literature. Fourth- and fifth-grade students (N = 90) completed a battery of sociometric measures at two different times separated by eight weeks. Friendship dyads were then identified using the following definitional criteria: (1) mutual positive nominations; (2) mutal high ratings (i.e., 4 or 5 on a five-point Likert-type scale); (3) one positive nomination reciprocated by a rating of 5; (4) one positive nomination and mutual high ratings; and (5) one positive nomination and mutual ratings averaging at least 4. Frequency and concordance analyses indicated differences across the five definitions. In addition, the friendships identified by each of the five definitions were similarly moderate in their stability. Explanations for, and the possible implications of, these differences are discussed.     

Semiparametric estimation of employment duration models

There are a variety of economic areas, such as studies of employment duration and of the durability of capital goods, in which data on important variables typically are censored. The standard techinques for estimating a model from censored data require the distributions of unobservable random components of the model to be specified a priori up to a finite set of parameters, and misspecification of these distributions usually leads to inconsistent parameter estimates. However, economic theory rarely gives guidance about distributions and the standard estimation techniques do not provide convenient methods for identifying distributions from censored data. Recently, several distribution-free or semiparametric methods for estimating censored regression models have been developed. This paper presents the results of using two such methods to estimate a model of employment duration. The paper reports the operating characteristics of the semiparametric estimators and compares the semiparametric estimates with those obtained from a standard parametric model.     

Upper Confidence Limits on Excess Risk for Quantitative Responses

The definition and observation of clear-cut adverse health effects for continuous (quantitative) responses, such as altered body weights or organ weights, are difficult propositions. Thus, methods of risk assessment commonly used for binary (quantal) toxic responses such as cancer are not directly applicable. In this paper, two methods for calculating upper confidence limits on excess risk for quantitative toxic effects are proposed, based on a particular definition of an adverse quantitative response. The methods are illustrated with data from a dose-response study, and their performance is evaluated with a Monte Carlo simulation study.     

Evaluation of treatment programs for persons with severe mental illness: moderator and mediator effects

This study evaluated several statistical models for estimating treatment effects in a randomized, longitudinal experiment comparing assertive community treatment (ACT) versus brokered case management (BCM). In addition, mediator and moderator analyses were conducted. The ACT clients had improved outcomes in terms of housing and psychiatric symptoms than BCM clients. Case management housing assistance and financial assistance partially mediated housing outcomes. No reliable mediators were found for psychiatric symptoms, and no reliable moderators were found for either housing or psychiatric symptoms. The study also made several important methodological advances in the analysis of longitudinal data in randomized experiments.
