Do perceptions of their partners’ childbearing desires affect young women’s pregnancy risk? Further study of ambivalence

We explore whether young women’s perceptions of their sexual partners’ childbearing desires contribute to their risk of pregnancy. We used weekly journal data collected from 787 young women to measure their childbearing desires and their perceptions of their partners’ childbearing desires. We then conducted hazard modelling to predict pregnancy risk with variables based on interactions between the women’s desires and their perceived partners’ desires. Models that include perceived partners’ desires perform better than one based on women’s desires alone. The best model contains three significant predictors: one confirms the importance of pronatal, ambivalent, and indifferent desires for pregnancy risk; one indicates that the perceived partners’ antinatal desires reduce women’s pregnancy risk; and one suggests that women who both perceive their partners accurately and are in agreement with them have a lower pregnancy risk. The results indicate that perceived partner data can improve prediction and enhance our understanding of pregnancy risk.     

Rejected by Family for Being Gay or Lesbian: Portrayals,Perceptions, and Resilience

A myriad of negative psychosocial outcomes face gay men and lesbians who experience rejection by their family for not being heterosexual. However, what constitutes rejection is not clear, and, more importantly, it is not known how resilience is fostered within such a context. This qualitative study sought to examine these issues by exploring the lived experiences of Australian gay men and lesbians who were previously or were currently experiencing family rejection because of their sexuality. A total of 21 in-depth, semistructured interviews were individually conducted and analyzed. Thematic analysis of the interviews revealed several themes that provided greater understanding of the portrayals and perceptions of family rejection; the impact of family rejection on mental health; and, importantly, how these individuals came to establish resilience in the face of experiencing family rejection. Limitations, directions for future research, and clinical implications of the findings are also discussed.     

Influence of Perceived Maternal Psychological Control on Academic Performance in Chinese Adolescents: Moderating Roles of Adolescents’ Age,Gender, and Filial Piety

Existing studies with East Asian samples have reported inconsistent findings on the association between parental psychological control and academic performance in children and adolescents. A moderation effect is present, when the magnitude or direction of the association between two variables significantly changes with another variable called a moderator. This study explored moderators for the association between maternal psychological control and academic performance. A total of 338 Chinese secondary school students aged 14–20completed self-report measures of perceived maternal psychological control, academic performance, and attitudes toward filial piety. Structural equation modeling suggested that adolescent age moderated the association of interest: the influence of perceived maternal psychological control on academic performance significantly varied between middle adolescents aged 14–17 and late adolescents aged 18–20. Based on the findings, this study offers a possible rationale for the inconsistent findings in studies with East Asian samples and proposes that parenting effect should be assessed developmentally.     

The situational logic of entrepreneurship: a realist approach to national policy

National policy initiatives to encourage entrepreneurial behaviour are often developed with limited knowledge of the contextual constraints and causal factors. In this paper, we adopt a social realist approach, generally associated with critical realism, as a framework for analysing levels of entrepreneurial behaviour. The trigger for our study is the apparent anomaly of low levels of German entrepreneurship. We apply the morphogenetic framework of the sociologist Margaret Archer to Germany and then compare this to the United States. We conclude that particular so-called situational logics at the intersection of structure and culture constitute mechanisms which provide strategic direction for the decisions of potential entrepreneurs. We argue that a social realist stance based upon Archer’s sociology provides a practical grounding for research and policy development.     

Developing management capability within a horizontal supply chain in performance measurement deployment and evolution: a Dynamic Capabilities and Goal Theory perspective

Abstract

Complex collaboration in rapidly changing business environments create challenges for management capability in Utility Horizontal Supply Chains (UHSCs) involving the deploying and evolving of performance measures. The aim of the study is twofold. First, there is a need to explore how management capability can be developed and used to deploy and evolve Performance Measurement (PM), both across a UHSC and within its constituent organisations, drawing upon a theoretical nexus of Dynamic Capability (DC) theory and complementary Goal Theory. Second, to make a contribution to knowledge by empirically building theory using these constructs to show the management motivations and behaviours within PM-based DCs. The methodology uses an interpretive theory building, multiple case-based approach (n = 3) as part of a USHC. The data collection methods include, interviews (n = 54), focus groups (n = 10), document analysis and participant observation (reflective learning logs) over a five-year period giving longitudinal data. The empirical findings lead to the development of a conceptual framework showing that management capabilities in driving PM deployment and evolution can be represented as multilevel renewal and incremental Dynamic Capabilities, which can be further understood in terms of motivation and behaviour by Goal-Theoretic constructs. In addition, three interrelated cross-cutting themes of management capabilities in consensus building, goal setting and resource change were identified. These management capabilities require carefully planned development and nurturing within the UHSC.     

Mitigating Inventory Overstocking: Optimal Order‐up‐to Level to Achieve a Target Fill Rate over a Finite Horizon

Service level agreements (SLAs) are widely adopted performance‐based contracts in operations management practice, and fill rate is the most common performance metric among all the measurements in SLAs. Traditional procedures characterizing the order‐up‐to level satisfying a specified fill rate implicitly assume an infinite performance review horizon. However, in practice, inventory managers are liable to maintain and report fill rates over a finite performance review horizon. This horizon discrepancy leads to deviation between the target fill rate and actual achieved fill rate. In this study, we first examine the behavior of the fill rate distribution over a finite horizon with positive lead time. We analytically prove that the expected fill rate assuming an infinite performance review horizon exceeds the expected fill rate assuming a finite performance review horizon, implying that there exists some inventory “waste” (i.e., overstocking) when the traditional procedure is used. Based on this observation and the complexity of the problem, we propose a simulation‐based algorithm to reduce excess inventory while maintaining the contractual target fill rate. When the lead time is significant relative to the length of the contract horizon, we show that the improvement in the inventory system can be over 5%. Further, we extend our basic setting to incorporate the penalty for failing to meet a target, and show how one can solve large‐scale problems via stochastic approximation. The primary managerial implication of our study is that ignoring the performance review horizon in an SLA will cause overstocking, especially when the lead time is large.     

Alternate Routing Strategies in Batch Manufacturing: An Evaluation

Batch manufacturing firms are experiencing significant changes because of technological developments in work center design, such as flexible manufacturing systems (FMS) and planning/control tools like computer-aided process planning (CAPP). These new developments provide production managers with some solutions to a number of complex problems. For example, numerical-controlled (NC) machine center installations are effective in providing quality parts because of tight tolerance specifications built into the equipment. However, these highly efficient centers create bottlenecks that constrain shop throughput, since production planners tend to rely too much on them. To help improve manufacturing planning, we introduce an important element to the batch production scheduling component of CAPP's mission—evaluating possible alternate routes. Production scheduling encompasses job route selection as well as machine center assignment (loading), job releasing, and setting due dates. In this paper, three routing strategies requiring different levels of shop floor information are tested and evaluated using computer simulation. Shop performance is measured by total cost and traditional measures of job flow time, lateness, and tardiness.     

REORDER-POINT MODELS WITH DISCRETE PROBABILITY DISTRIBUTIONS

This paper is concerned with the determination of reorder points and safety-stock levels for situations where both the demand and lead-time distributions are discrete and independent. Formulas are developed for computing exact probabilities for the lead-time demand distribution on the basis of empirical distributions. Practitioners can use the model to obtain exact probabilities for situations where the computational burden is justified, while academicians can use the model to evaluate heuristic approaches to the reorder-point problem.
