Statistical Inference for Transformation Inhomogeneous Point Processes

Abstract.  Statistical inference for exponential inhomogeneous Markov point processes by transformation is discussed. It is argued that the inhomogeneity parameter can be estimated, using a partial likelihood based on an inhomogeneous Poisson point process. The inhomogeneity parameter can thereby be estimated without taking the interaction into account, which simplifies the statistical analysis considerably. Data analysis and simulation experiments support the results.     

Ethical leadership: A review and future directions

Our literature review focuses on the emerging construct of ethical leadership and compares this construct with related concepts that share a common concern for a moral dimension of leadership (e.g., spiritual, authentic, and transformational leadership). Drawing broadly from the intersection of the ethics and leadership literatures, we offer propositions about the antecedents and outcomes of ethical leadership. We also identify issues and questions to be addressed in the future and discuss their implications for research and practice. Our review indicates that ethical leadership remains largely unexplored, offering researchers opportunities for new discoveries and leaders opportunities to improve their effectiveness.     

The Role of Assertiveness and Decision Making in Early Adolescent Substance Initiation: Mediating Processes

This study examined the mediating processes linking assertiveness and decision making to early adolescent substance initiation, along with the moderating effect of gender on those processes. Models specifying negative expectancies and refusal intentions as mediators of individual rights assertiveness and decision‐making effects on substance initiation were evaluated across 18 months on a nontreatment cohort of young adolescents participating in a prevention trial (average age 12.3 years at baseline; N=357). Results indicated that individual rights assertiveness and decision making had indirect effects on substance initiation through effects on negative outcome expectancies and refusal intentions. Gender differences were found in both the average level and the pattern of relationships among the variables. For girls, refusal intentions were negatively associated with later substance initiation. For boys, early levels of substance initiation were negatively associated with later levels of negative expectancies and refusal intentions. Implications for prevention programming are discussed.     

Authorizing processes changing team autonomy during new product development

One basic feature of recent collaborative team arrangements for organizing new product development is a high degree of autonomy for cross-functional teams. The literature, however, has not provided a very precise analysis of team autonomy in the context of new product development. The theoretical framework advanced here, based on the literature and the authors' case studies, assumes that developing a large and technologically sophisticated new product requires a hierarchy of collaborating teams. In this complex organizational context, managers do not completely predetermine any one team's autonomy. During the course of a new product development program, certain authorizing (deauthorizing) processes produce ad hoc changes in autonomy. This paper identifies specific authorizing processes and hypothesizes about variables that should affect them. The propositions also lead to some managerial implications for preserving team autonomy.     

Family policy in Sweden

Sweden has a well-developed family policy, organized around the goals of family economic security and physical well-being, voluntary parenthood, gender equality, and children's rights. This article provides a comprehensive analysis of family policy in Sweden, beginning with a brief history of the development of family policy goals and a consideration of the reasons for the consensus on family policy goals that has arisen. Details are provided on programs designed to reach goals, and the success of these programs is evaluated. The impact of recent economic and political developments on the future of family policy making in Sweden is also discussed.She is also Adjunct Professor of Women's Studies. Her research interests focus on work-family linkages in industrial societies and their implications for gender equity. She is currently researching the impact of corporate culture on men's participation in child care in Sweden. She received her Ph.D. in Sociology from the University of Wisconsin at Madison.     

Political Beliefs in an Era of Economic Decline: Farmers' Attitudes Toward State Economic Intervention,Trade, and Food Security1

Abstract The effects of the economy on political attitudes is a longstanding sociological issue that is receiving renewed attention in the face of recent U.S. economic downturns. While the impacts of the farm crisis on financial and household well-being of farm operators have been addressed by a number of studies, few have explored its political outcomes. Four perspectives that consider how economic forces translate into political beliefs are outlined, two reflecting objective economic position (class location and financial pressure) and two indicating subjective appraisals (feelings of economic uncertainty and subjective deprivation). Data from a sample of Ohio farm operators for 1987 are used to analyze how the perspectives are related to progressive beliefs about farming, the domestic nonfarm economy, and third-world food production. Indicators of objective economic position and subjective appraisals have relatively limited impact on farmers' political attitudes. Of these indicators, subjective appraisals were more closely related to attitudes. In addition, operators' stances on farm political issues also affect their views on domestic nonfarm and third-world policy agendas. Implications were found for studies of farmers' political attitudes as well as for broader sociological theory regarding the development of progressive attitudes during periods of economic decline.     

Fallen apples

Children today often have to cope with living in fractured family systems in which multigenerational dysfunction and abuse is passed on to them. As a result, they often make decisions that lead them into unsafe, and possibly disastrous situations. Some children and adolescents cannot see beyond today. They are prone to giving up because they feel nothing can change. Growing up in physically violent homes can create children who are unable to control their own violent rages. While hospitalized, they often seek the struggle and emotional release that accompanies physical management. Physical management allows the children to be out of control and safe at the same time.
