Using Discrete-Time Event History Fertility Models to Simulate Total Fertility Rates and Other Fertility Measures

Event history models, also known as hazard models, are commonly used in analyses of fertility. One drawback of event history models is that the conditional probabilities (hazards) estimated by event history models do not readily translate into summary measures, particularly for models of repeatable events, like childbirth. In this paper, we describe how to translate the results of discrete-time event history models of all births into well-known summary fertility measures: simulated age- and parity-specific fertility rates, parity progression ratios, and the total fertility rate. The method incorporates all birth intervals, but permits the hazard functions to vary across parities. It can also simulate values for groups defined by both fixed and time-varying covariates, such as marital or employment life histories. We demonstrate the method using an example from the National Survey of Family Growth and provide an accompanying data file and Stata program.     

Heterogeneity in Parent‐reported Social Skill Development in Early Elementary School Children

Despite known risks associated with aberrant social skill development, there has been a relative dearth of literature on typical developmental changes in social skills over time. In this study, we examine systematic changes in social skills from kindergarten (typical age of 5–6 years) to third grade (typical age of 8–9 years), and focus on systematic heterogeneity across these developmental trajectories. Data came from the National Head Start—Public School Early Childhood Transition Demonstration Project (N = 6964). Mixture models provide evidence for multiple classes of individuals representing heterogeneity in the development of social skills. Classes were defined as a majority class (whose trajectories remained relatively stable over time), an increasing class (whose trajectories increased at a faster rate than the majority class), and a decreasing class (whose trajectories decreased at a faster rate than the majority class). Developmental trends accounted for a substantial proportion of the variance in social skill components. Implications and limitations of the study are discussed.     

A Mission of Civic Engagement: Undergraduate Students Working with Nonprofit Organizations and Public Sector Agencies to Enhance Societal Wellbeing

Universities in the U.S. have been criticized for not contributing enough to the social well-being of the communities within which they operate, and business schools have been accused of failing to prepare students adequately for careers in business. These criticisms have led to increased focus on service learning, a form of experiential learning that aids students in the application of theoretical knowledge to “real-life” situations—including problems and opportunities—faced by local as well as international communities. Even though service-learning has become fairly popular in business schools throughout the U.S., there is relatively little literature that illuminates its application. Thus, the present article describes a service-learning project in a marketing research course and how this project supports the university’s mission of civic engagement. Included are also a discussion of course-specific objectives as well as learning goals, objectives, and assessments as commonly required by regional and national accreditation agencies.     

Agency Problems between Managers and Employees in Nonprofit Organizations: A Discrete Choice Experiment

Most principal–agent literature of nonprofit organizations has focused on the relationship between board members and managers. However, in addition to the role as an agent of the board, the manager also performs a role as principal with respect to the nonprofit employees. By using a discrete choice experiment, we identify the objectives of managers and employees in nonprofit organizations and assess the presence of agency problems in this relationship. Our sample consists of 76 headmasters, 161 teachers, and 39 administrative employees in 74 secondary nonprofit schools in Belgium. We find that the six objectives set out in the experiment play an important role for both headmasters and subordinate staff. However, the results also indicate that some of these objectives are significantly more important for the headmasters. In sum, our results suggest that agency theory and stewardship theory are not necessarily in conflict with each other but can be combined into a more general governance framework for nonprofit organizations. Consequently, we argue that incentive structures that incorporate different types of objectives can facilitate the recruitment and retention of employees in nonprofit organizations.     

The Employment Experience of Refugees in the Netherlands1

This study focuses on the economically disadvantaged position of refugees. We use survey data of refugees from Somalia, Iran, Afghanistan, Iraq, and the former Yugoslavia in the Netherlands, to analyze refugees’ odds of employment and their occupational status. In line with human capital and social capital theory, we find that host country specific education, work experience, language proficiency, and contacts with natives are positively related to the chances of employment and occupational status. The study shows that health problems, integration courses, and the time spent in refugee reception centers form important additional explanations of the economic integration of refugees.     

Performance Evaluations as Gender Barriers in Professional Organizations: A Study of Auditing Firms

Gendering processes often take the form of organizational subtexts, that is, seemingly gender‐neutral practices that have gender implications. The purpose of this article is to study performance evaluations, which, based on management by objectives systems, may appear neutral, but tend to be based on male norms of what is regarded as good performance. We analysed the careers and performance evaluations of 391 newly licenced Swedish auditors, using an open‐ended question survey. In this industry 50 per cent of new employees and 92 per cent of partners are men. Even in the early stages of their careers, there are notable differences between women and men. The women achieved less and show lower career ambitions and expectations as well as greater intentions to leave the auditing industry. Performance evaluations are also perceived differently, men focusing on what is evaluated (reflecting the perceptions of those at higher hierarchical levels) and women focusing on who does the evaluating and how.     

A Couple-Based Approach to the Reduction of PTSD Avoidance Symptoms: Preliminary Findings

This study reports preliminary findings regarding the feasibility and efficacy of a novel couple-based treatment, named Strategic Approach Therapy (SAT), for reducing avoidance symptoms of posttraumatic stress disorder (PTSD). Six male Vietnam combat veterans diagnosed with PTSD and their cohabitating marital partners participated in 10 weeks of SAT treatment. Self-report, clinician ratings, and partner ratings of PTSD symptoms were obtained before the first session and after the tenth session of treatment. Veterans reported statistically significant reductions in self-reported, clinician-rated, and partner-rated effortful avoidance, emotional numbing, and overall PTSD severity. These data indicate that SAT offers promise as an effective treatment for PTSD avoidance symptoms.     

An environmental life cycle optimization model for the European pulp and paper industry

Will paper recycling reduce the environmental impact of the European pulp and paper sector? If so, is maximal paper recycling the best policy to optimize the life cycle of the pulp and paper sector? We explore these questions using an approach that combines materials accounting methods and optimization techniques. Environmental impact data are inputs for a linear programming network flow model to find optimal configurations for the sector. These configurations consist of a mix of different pulping technologies, a geographical distribution of pulp and paper production, and a level of recycling consistent with the lowest environmental impacts. We use the model to analyse scenarios with different recycling strategies. Recycling offers a reduction in environmental impact in regions with a high population and a large production of paper and board products. Regions with a large production of graphic products should focus on cleaner virgin pulp production with energy recovery. We conclude that relocation of paper production also offers a reduction in environmental impact. However, the severe effects on the economy make this policy less attractive than a combination of recycling, cleaner pulp production and energy recovery.     

European management: An emerging competitive advantage of European nations

This article extends the debate begun in the June 1992 issue of EMJ when the authors first criticized Michael Porter's explanatory framework in his Competitive Advantage of Nations (1990), over the role of national culture on the competitive advantage of nations. In this paper, Frans van den Bosch and Arno van Prooijen stress that Europe is a locus of competitive advantage if one is prepared to pay attention to the possibility of ‘European Management’ as a potential asset of European firms. In this connection, the transnationalization of European firms is of importance.
