The influence of flexible management practices on the sharing of experiential knowledge in the workplace: a case study of food service helpers

Previous studies have shown that the job knowledge and prudent knowledge of experienced workers constitute a wealth that needs to be shared in workplaces to promote worker integration, job retention and occupational health and safety. It appears, however, that certain management practices undermine this knowledge sharing process. This case study of food service helpers in institutional food service departments is part of a research project aimed at comparing the impact of different work organization methods on knowledge sharing in the workplace on the basis of case studies carried out in several organizations. The results of this case study reveal that by destabilizing and weakening the work teams, flexible management practices create an environment that is not conducive to experiential knowledge sharing.     

Flexible Work Options and Mothers' Perceptions of Career Harm

Whether or not mothers, who often struggle with balancing work and parenting responsibilities, perceive that they face career harm in exchange for control over flexible work options at their jobs is an unanswered question. Using 2009 original data from a random‐digit‐dial telephone survey of 441 mothers located across the United States, this study focuses on how control over two latent variables measuring flexibility, flexible work arrangements (such as scheduling and place of work) and time‐off options, influences mothers' career harm perceptions in a total of three work domains: (1) wages/earnings, (2) raises or promotions, and (3) job evaluations. We find perceptions of career harm among only one‐fifth of mothers; in addition, control over time‐off options reduced perceived career damage related to parenting duties. Mothers may have less to fear than previously hypothesized about the potential sacrifices they have to make when they have significant control over certain flexibility options.     

Fighting the odds: strategies of female caregivers of disabled children in Zimbabwe

Caregivers of disabled children face numerous challenges in meeting their child’s needs. Research on Zimbabwean caregivers of disabled children is limited. Yet the difficult socio-economic, political and institutional context is expected to complicate the caregiving task. This article examines the resources and caring strategies of female caregivers in Mutare, Zimbabwe, using a well-being framework. Through a mixed-methods approach, the data reveals that external support is extremely limited, particularly due to stigma and a weak state. Caregivers are mostly self-reliant and their strategies focus on enabling themselves to take care of their child.     

Data-Intensive Science and Research Integrity

In this commentary, we consider questions related to research integrity in data-intensive science and argue that there is no need to create a distinct category of misconduct that applies to deception related to processing, analyzing, or interpreting data. The best way to promote integrity in data-intensive science is to maintain a firm commitment to epistemological and ethical values, such as honesty, openness, transparency, and objectivity, which apply to all types of research, and to promote education, policy development, and scholarly debate concerning appropriate uses of statistics.     

The poor availability of syntaxes of structural equation modeling

The syntax or codes used to fit Structural Equation Models (SEMs) convey valuable information on model specifications and the manner in which SEMs are estimated. We requested SEM syntaxes from a random sample of 229 articles (published in 1998–2013) that ran SEMs using LISREL, AMOS, or Mplus. After exchanging over 500 emails, we ended up obtaining a meagre 57 syntaxes used in these articles (24.9% of syntaxes we requested). Results considering the 129 (corresponding) authors who replied to our request showed that the odds of the syntax being lost increased by 21% per year passed since publication of the article, while the odds of actually obtaining a syntax dropped by 13% per year. So SEM syntaxes that are crucial for reproducibility and for correcting errors in the running and reporting of SEMs are often unavailable and get lost rapidly. The preferred solution is mandatory sharing of SEM syntaxes alongside articles or in data repositories.     

Attention-deficit/hyperactivity disorder–specific stimulant misuse,mood, anxiety,and stress in college-age women at high risk for or with eating disorders

ABSTRACT

Objective: To examine the misuse of attention-deficit/hyperactivity disorder (ADHD)-specific stimulants in a college population at high risk for or with clinical or subclinical eating disorders. Participants: Four hundred forty-eight college-age women aged 18–25 at high risk for or with a clinical or subclinical eating disorder. Methods: Participants completed assessments of stimulant misuse and psychopathology from September 2009 to June 2010. Results: Greater eating disorder pathology, objective binge eating, purging, eating disorder–related clinical impairment, depressive symptoms, perceived stress, and trait anxiety were associated with an increased likelihood of stimulant misuse. Subjective binge eating, excessive exercise, and dietary restraint were not associated with stimulant misuse. Conclusions: ADHD-specific stimulant misuse is associated with eating disorder and comorbid pathology among individuals at high risk for or with clinical or subclinical eating disorders. Screening for stimulant misuse and eating disorder pathology may improve identification of college-age women who may be engaging in maladaptive behaviors and inform prevention efforts.     

Seeing Eye to Eye: Predicting Teacher–Student Agreement on Classroom Social Networks

This study examines the association between classroom characteristics and teacher–student agreement in perceptions of students' classroom peer networks. Social network, peer nomination, and observational data were collected from a sample of second through fourth grade teachers (N = 33) and students (N = 669) in 33 classrooms across five high‐poverty urban schools. Results demonstrate that variation in teacher–student agreement on the structure of students' peer networks can be explained, in part, by developmental factors and classroom characteristics. Developmental increases in network density partially mediated the positive relationship between grade level and teacher–student agreement. Larger class sizes and higher levels of normative aggressive behavior resulted in lower levels of teacher–student agreement. Teachers' levels of classroom organization had mixed influences, with behavior management negatively predicting agreement, and productivity positively predicting agreement. These results underscore the importance of the classroom context in shaping teacher and student perceptions of peer networks.     

The Limits of Sharing: An Ethical Analysis of the Arguments For and Against the Sharing of Databases and Material Banks

In this article, I study the challenges that make database and material bank sharing difficult for many researchers. I assert that if sharing is prima facie ethical (a view that I will defend), then any practices that limit sharing require justification. I argue that: 1) data and material sharing is ethical for many stakeholders; 2) there are, however, certain reasonable limits to sharing; and 3) the rationale and validity of arguments for any limitations to sharing must be made transparent. I conclude by providing general recommendations for how to ethically share databases and material banks.     

Teen Sexual Behavior: Applicability of the Theory of Reasoned Action

We examined the utility of the theory of reasoned action for predicting sexual intercourse among teenagers and determined whether it holds for both genders and for those with and without prior sexual experience. The data include 749 students who were in 9th–11th grades when the predictors were measured and in 10th–12th grades when sexual intercourse was assessed. About half (53%) were girls, about half (48%) were non‐Hispanic European Americans. Results showed that prior sexual experience was related to a higher rate of sexual intercourse, but boys and girls did not differ. Tests of the causal model for subgroups (boy and girl virgins, boy and girl nonvirgins) yielded similar results. As predicted, paths from intentions to behavior and from norms and attitudes to intentions were significant, as were paths from outcome and normative beliefs to attitude and norm, respectively.     

Immigration,investment, and real wages

When a country is the recipient of large-scale, politically motivated immigration – as has been the case for Israel in recent years – the initial impact is to reduce real wages. Over the longer term, however, the endogenous response of investment, together with increasing returns, may well actually increase real earnings. If immigration itself is not wholly exogenous, but respond to real wages, they may be multiple equilibria, that is, optimism or pessimism about the success of the economy at absorbing immigrants may constitute a self-fulfilling prophecy.
