Purpose

Questionable research or reporting practices (QRPs) contribute to a growing concern regarding the credibility of research in the organizational sciences and related fields. Such practices include design, analytic, or reporting practices that may introduce biased evidence, which can have harmful implications for evidence-based practice, theory development, and perceptions of the rigor of science.

Design/Methodology/Approach

To assess the extent to which QRPs are actually a concern, we conducted a systematic review to consider the evidence on QRPs. Using a triangulation approach (e.g., by reviewing data from observations, sensitivity analyses, and surveys), we identified the good, the bad, and the ugly.

Findings

Of the 64 studies that fit our criteria, 6 appeared to find little to no evidence of engagement in QRPs and the other 58 found more severe evidence (91 %).

Implications

Drawing upon the findings, we provide recommendations for future research related to publication practices and academic training.

Originality/value

We report findings from studies that suggest that QRPs are not a problem, that QRPs are used at a suboptimal rate, and that QRPs present a threat to the viability of organizational science research.

In this article, I consider the harms inflicted upon transgender persons through “misgendering,” that is, such deployments of gender terms that diminish transgender persons' self‐respect, limit the discursive resources at their disposal to define their own gender, and cause them microaggressive psychological harms. Such deployments are morally contestable, that is, they can be challenged on ethical or political grounds. Two characterizations of “woman” proposed in the feminist literature are critiqued from this perspective. When we consider what would happen to transgender women upon the broad implementation of these characterizations within transgender women's social context, we discover that they suffer from two defects: they either exclude at least some transgender women, or else they implicitly foster hierarchies among women, marginalizing transgender women in particular. In conclusion, I claim that the moral contestability of gender‐term deployments acts as a stimulus to regularly consider the provisionality and revisability of our deployments of the term “woman.”  相似文献

Purpose

An item-sort task is a common method to reduce over-representative item lists during the scale-creation process. The current article delineates the limitations and misapplications of the accepted statistical significance formula for item-sort tasks and proposes a new statistical significance formula with greater utility across a wider range of item-sort tasks.

Design

First, a simulation study compares the two formulas in an array of conditions that vary on sample size and number of assignment choices. Second, an empirical study compares the results of three separate item-sort tasks across the two formulas for statistical significance.

Findings

In the empirical study, the proposed formula produces more correct retention decisions than the existing formula across all three item-sort tasks. In the simulation study, the proposed formula is more appropriate than the existing formula under most conditions. The two formulas function identically in item-sort tasks with only two assignment choices.

Implications

Researchers could obtain erroneous results when misapplying the existing item-sort task statistical significance formula to cases with more than two assignment choices. The proposed formula corrects this limitation, ultimately providing accurate results more often than the existing formula. Applying the proposed formula could help future research and practice throughout the scale development process.

Originality

Despite widespread use, few attempts have been made to improve scale-creation pretest methods, particularly item-sort tasks. The current study demonstrates that even conventional statistical methods are susceptible to misuse and misapplication, and future research could benefit from the reexamination of other common methods.

Proactive and reactive aggression represent distinct functions of aggression that are associated with different risk factors, including individual and contextual characteristics. However, more research evaluating the interactive effects of risk factors is needed. The current study evaluated whether corporal punishment moderated the influence of neighborhood problems and anger coping on proactive and reactive aggression in a child psychiatric inpatient sample of 6 to 13 year olds (n?=?151). Findings were compared across child- and caregiver-reports of aggression. Consistent with expectations, anger coping was more strongly associated with reactive aggression than proactive aggression across informants. In contrast, perceived neighborhood problems were only associated with child-reports of proactive aggression, with corporal punishment moderating this association. Specifically, the association between neighborhood problems and proactive aggression was only evident at high levels of corporal punishment. Treatment implications and future directions are discussed.  相似文献

Exposure to violence (ETV) has emerged as a key and stable predictor of violent offending. However, not all youth offenders who experience ETV go on to chronic violent offending. Consequently, it is possible that individual differences, such as psychopathic traits, may be an important factor in the link between ETV and violent offending. These traits are associated with exposure to violence and, separately, to violent offending. The present study used data from Pathways to Desistance, a multisite, longitudinal study of serious juvenile offenders (N = 1170, Meanage = 16.05, SD = 1.16) to explore these relationships, simultaneously. First, autoregressive cross-lagged path models were used to examine the longitudinal bivariate relations among violent offending, ETV, and psychopathic traits. Second, latent class growth analysis was used to determine trajectories ETV. And third, the mediating influence of psychopathic traits was examined. Results indicated that ETV predicted later engagement in violence, but there was some degree of reciprocity between ETV and violence over time. Additionally, respondents with stable high or increasing trajectories of ETV reported more instances of violent offending. Finally, psychopathic traits mediated the relationship between ETV and violent offending. Together these findings support the notion that individuals with psychopathic traits perceive and internalize their environment differently than others and that this difference guides their own violent offending. Given the importance of psychopathic traits for understanding the influence of ETV on violent offending, prevention and intervention strategies must be developed that take into account both individual differences and environmental factors.  相似文献

This study set out to investigate parental attitudes toward entrepreneurship education as evaluative directing components of social representations. A nationwide sample of parents (N = 625) was asked to indicate their opinions on a set of statements about entrepreneurship education. The parents’ attitudinal orientation suggested that they would rather avoid entrepreneurship education than approach it. Additionally, parental evaluations contained indecision and polarised opinions, and most parents saw it as unlikely or were unsure whether their children would become entrepreneurs. Parental attitudes correlated with the established representations of education and subsequent policy stands, suggesting that entrepreneurship education has been made familiar by anchoring attitudes in the field of educational debates. It was suggested that current trends in educational policy and work life may stimulate the formation of polemical social representations pertaining to entrepreneurship education.  相似文献

Individuals with high intolerance of uncertainty (IU) have been shown to exhibit abnormal threat responding, which may be mediated by hyperactive anterior insula (aINS) response to uncertainty. Research has indicated that individuals with high IU also exhibit abnormal positive valence responding, suggesting that IU may impact responding to uncertainty regardless of the valence of the potential outcome. To date, no study has investigated the neural processes associated with IU and response to uncertain positive stimuli, such as rewards. Therefore, this study was designed to examine the association between individual differences in IU and neural activation during uncertain reward using functional magnetic resonance imaging (fMRI). Thirty-seven adults completed a self-report measure of IU and a reward task during fMRI. Consistent with the threat literature, greater IU was associated with increased aINS activation during uncertain reward. This association was more robust for the prospective IU subscale, a dimension characterized by worry about future events. Together with prior studies, these findings provide evidence that IU is related to abnormal threat and reward responding, and that these deficits may be similarly linked to hyperactive aINS response to uncertainty.  相似文献

Pathological gambling is characterized by excessive gambling behavior which influences the life and well-being of a person in a dysfunctional way. It often leads to severe consequences in social and family life, career and material matters. This can also include illegal acts. In the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) excessive gambling was classified under impulse-control disorders but was renamed as gambling disorder (GD) and reclassified under the category “substance-related and addictive disorders” in DSM-5, due to parallels to substance use disorders in the clinical characteristics as well as genetic and neurobiological factors. In Germany, approximately 0.5?% of the adult population suffer from GD. Especially gambling machines are associated with an increased risk of gambling-related problems. Common comorbidities are substance-related and affective disorders. The most important risk factors are young age, male gender, a history of migration, gambling-related problems in the family, unemployment, a low educational level and low household income. Delinquent behavior was not considered to be a sufficiently discriminative factor for GD, although there is a correlation between delinquency and gambling behavior. In addition, those GD subjects who show delinquent behavior also show a specific risk profile. Thus, mental health professionals should be aware of possible psychosocial consequences in GD, such as illegal acts, and this should be addressed in the effective treatment strategies, such as cognitive behavioral therapy. Moreover, it is necessary to improve the access routes for affected people into healthcare system in order to ensure early detection and treatment of the disease.  相似文献
