Early Maternal Depression and Social Skills in Adolescence: A Marginal Structural Modeling Approach

Early maternal depression is a risk factor that may have adverse effects on adolescent social skills. Although evidence indicates links between early maternal depression and social outcomes during early childhood, whether an association extends to adolescence needs further examination. We tested the possible long‐term association between early maternal depression and adolescent social skills using a national secondary dataset. A secondary objective was to test if maternal parenting at the transition to adolescence mediated the association, with the notion that adverse outcomes of early maternal depression could be ameliorated by positive parenting practices at an important developmental transition. Data were obtained from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Marginal structural modeling within the context of structural equation modeling revealed a significant association between early maternal depression and adolescent social skills while controlling for maternal depression during pre‐adolescence and adolescence. Maternal parenting skills partially mediated the association between early maternal depression and mother report of adolescent social skills. These findings have important implications for understanding the link between early maternal depression and adolescent social skills, and for informing parenting practices during pre‐adolescence.     

A return to work program for injured workers: a reassignment model

The current workers' compensation system does not encourage permanently restricted workers who are disabled due to work related injuries to return to work. Workers are often labeled permanently disabled and are released from their positions with their employers. However, according to the Americans with Disabilities Act of 1990, these individuals may be qualified to return to productive employment. This paper will describe a Reassignment Model for occupational therapy supported by the rehabilitation frame of reference. This Model presents reassignment to a vacant position as a reasonable accommodation to return injured workers to productive employment. A case study will illustrate the successful implementation of the model. The potential benefits of using this Model will be described for clients, society, employers, and the occupational therapy profession.     

Success of research-based spin-offs. State-of-the-art and guidelines for further research

The topic of this paper is research-based spin-offs from public organisations. The initial point is a discussion about the economic benefit of such companies. The paper investigates factors influencing the generation, development, and growth of research-based spin-offs built on scientific know-how or research results. An analysis of previous empirical studies allows the identification of three main groups of success factors, concerning the founder, the environment, and the later company itself. Based on Gartner’s framework of new venture creation—used as a structure-building tool and substitute of entrepreneurial theory—we give an overview of entrepreneurial success factors. We also identify inconsistencies and gaps in empirical evidence and guidelines for further research. Particular explanation seems to be necessary for incentives, ideas, and incubation environments, all having an impact on formation and performance of spin-offs.      

The Impact of Estimation: A New Method for Clustering and Trajectory Estimation in Patient Flow Modeling

The ability to accurately forecast and control inpatient census, and thereby workloads, is a critical and long‐standing problem in hospital management. The majority of current literature focuses on optimal scheduling of inpatients, but largely ignores the process of accurate estimation of the trajectory of patients throughout the treatment and recovery process. The result is that current scheduling models are optimizing based on inaccurate input data. We developed a Clustering and Scheduling Integrated (CSI) approach to capture patient flows through a network of hospital services. CSI functions by clustering patients into groups based on similarity of trajectory using a novel semi‐Markov model (SMM)‐based clustering scheme, as opposed to clustering by patient attributes as in previous literature. Our methodology is validated by simulation and then applied to real patient data from a partner hospital where we demonstrate that it outperforms a suite of well‐established clustering methods. Furthermore, we demonstrate that extant optimization methods achieve significantly better results on key hospital performance measures under CSI, compared with traditional estimation approaches, increasing elective admissions by 97% and utilization by 22% compared to 30% and 8% using traditional estimation techniques. From a theoretical standpoint, the SMM‐clustering is a novel approach applicable to any temporal‐spatial stochastic data that is prevalent in many industries and application areas.     

Predictors of Student Health Care Utilization Patterns

Abstract

In recent years, interest has been renewed concerning student utilization and nonutilization of university and college health services. A study was conducted at James Madison University to examine for prediction purposes: (a) student utilization patterns; (b) knowledge of available services; and (c) attitudes toward the student health service. Questionnaires were sent to a 10% random sample of the student population. Employing multiple regression analysis, the predictive value of the independent variables of knowledge, attitudes, convenience, and sociodemographic data were evaluated for the three criterion (dependent) variables related to utilization and non-utilization of health services. These had been identified as (1) frequency of use, (2) number of different types of use, and (3) user-nonuser. Results of the analysis indicated that certain predictor variables could predict to an extent the utilization and nonutilization patterns of students. The implications of these findings as well as their reflections on previous studies are discussed.     

Reclaiming Life: Six Consumers of Mental Health Services Talk About What Helped and What Did Not Help Them Get Their Lives Back

This article summarizes a roundtable discussion held at Thresholds in Chicago, Illinois in September 2012, where six people diagnosed with serious mental illness talked about what helped and did not help them recover and successfully reclaim their lives. Their comments, taken as part of their personal narratives, can help enhance understanding of the recovery process. The discussion is organized by the themes that emerged: considering life as distinct from diagnosis, meeting basic needs, empowerment, education, community, faith and hope, healthy thinking, peers, and focus on wellness. Panel members also offer advice for mental health service providers.     

OR in the paper industry

The paper reviews the applications of OR in the paper industry and concludes that acceptance of OR is in general very poor. Some of the possible reasons for this are discussed, along with prospects for the future.     

Beyond taxonomy

Much of the considerable confusion about the definition of social entrepreneurship in academic literature stems from a lack of empirical research on the subject. This article advances social entrepreneurship research beyond conceptualization discussions by developing and validating an instrument that quantifies the incidence of nonprofit entrepreneurial behavior. Information from 145 Kansas City Metropolitan Area nonprofit organizations was collected to validate the underlying constructs represented in the instrument. Behavior differences were depicted between entrepreneurial and nonentrepreneurial nonprofits. Using principal component factor analysis, the research illustrates social entrepreneurship as a unique nonprofit behavior that occurs at the intersection of innovation, proactiveness, and risk taking.     

A Matter of Reputation and Pride: Associations between Perceived External Reputation,Pride in Membership,Job Satisfaction and Turnover Intentions

This study investigates how job satisfaction and turnover intentions are related to external reputation as perceived by employees and their pride in membership. Based on a cross‐sectional survey including 439 employees, it also provides insights into external reputation as a possible source of collective pride. Study results indicate that, in agreement with social identity theory, outsiders' views of the organization are closely associated with employees' pride in organizational membership as well as job satisfaction. Both pride and job satisfaction mediate the relationship between perceived external reputation and turnover intentions. Hence, a favourable reputation matters in managing turnover intentions and is closely related to employee pride and satisfaction. Tenure of employees is positively associated with pride while intensive customer contact is negatively related to perceived external reputation and pride. Implications pinpoint the need for alignment of reputation management and human resources management. Furthermore, managers need to focus on new staff and employees with frequent customer contact and should implement pride‐building strategies according to the tenure of employees and intensity of customer contact.
