The Relationship

Four waves of longitudinal data were used to examine the relationship between the use of alcohol, marijuana, and cocaine and aggression from early adolescence into adulthood. The prevalence of fighting while using drugs (i.e., acute effects) was higher for alcohol than for marijuana and cocaine. A series of nested structural equation models examined the cross-sectional and long-term longitudinal interrelationships between each type of drug use and aggressive behavior. While alcohol use was not significantly related to later aggressive behavior at any age, both marijuana and cocaine use were significantly related to later aggression. In contrast, aggressive behavior did not significantly predict later alcohol, marijuana, or cocaine use. Overall, these data suggest that the long-term as well as acute relationships between aggression and drug use vary by drug type and stage of the life cycle.

The Relationship

The importance of human resource management (HRM) practices to improve organizational attitudes and behaviors is not yet widely acknowledged. However, is not clear whether the effect of HRM practices on outcomes vary depending on the level of specific personal resources. The present paper aims to examine the relationship between HRM practices and work engagement by focusing on the moderating role of adaptability. We used cross-sectional data with surveys from 1219 Italian employees in public, private, and non-profit organizations. The results of structural equation models (SEM) showed that HRM practices were positively related to work engagement overall for employees with low adaptability. Therefore, adaptability moderated the relationship between HRM practices and work engagement. In terms of originality, this study is based on the paucity of empirical studies linking developmental HR practices to employees’ work engagement. Hence, the present study addressed this gap by examining the relationship between the perception of HRM practices and work engagement, as well as how adaptability moderated this relationship. These findings are discussed in terms of their theoretical and practical implications for HRM.

Background:The literature has shown that workaholism acts at the root of burnout, but research regarding these constructs in the nursing profession is scant. Similarly, little attention has been paid to the impact of workaholism on disillusion, which is a dimension of burnout linked to professional vocation.Objectives:Contribute to the ongoing research on the relationship between workaholism and burnout among nurses. Moreover, this study considers disillusion as a dimension to be considered when investigating the relationship between workaholism and burnout, since nursing entails professional vocation.Method:The study followed a cross-sectional design. 614 nurses of six hospitals in South Italy have compiled two Self-report questionnaires: the Dutch Utrecht WorkAholism Scale (workaholism - Italian version) and the Link Burnout Questionnaire (burnout). Part of the group of subjects was diagnosed with both syndromes or considered at risk of developing them. The impact of workaholism on burnout was examined using Structural Equation Models for each variable.Results:More than 26% of the nurses are affected by burnout whereas 21% are workaholics. Working excessively proved to be a good predictor of both psychophysical exhaustion and disillusion.Conclusions:Nurses are at risk of workaholism and burnout. The study shows that workaholism is a predictor of nurses’ burnout, in particular working excessively (a dimension of workaholism) affects their psychophysical well-being and professional vocation.

The Relationship

Psychopathic traits and a history of traumatic brain injury (TBI) are common among imprisoned individuals. Although previous research has examined correlates of TBI among juvenile offenders, little research has explored the relationship between psychopathic traits and TBI among this population. Study objectives included: (1) examine the association between the history of a TBI and psychopathic traits among juvenile offenders and (2) determine if the history of a TBI predicts the manifestation of different psychopathic factors among juvenile offenders. Cross-sectional data from the Multidimensional Youth Residential Inventory consisted of 226 juvenile offenders. Bivariate and multivariate analyses were conducted. Results of linear regression analyses showed that history of a TBI significantly predicted callous unemotional and impulsive irresponsible traits. Clinical implications suggest early intervention is needed to treat the potential long-term effects of TBIs and the development of psychopathic traits. Recommendations for further research are discussed.

The Impact

We aimed to examine the complex relationships between patient safety processes and outcomes and multimorbidity using a comprehensive set of constructs: multimorbidity, polypharmacy, discordant comorbidity (diseases not sharing either pathogenesis nor management), morbidity burden and patient complexity. We used cross-sectional data from 4782 patients in 69 primary care centres in Spain. We constructed generalized structural equation models to examine the associations between multimorbidity constructs and patient-reported patient safety (PREOS-PC questionnaire). These associations were modelled through direct and indirect (mediated by increased interactions with healthcare) pathways. For women, a consistent association between higher levels of the multimorbidity constructs and lower levels of patient safety was observed via either pathway. The findings for men replicated these observations for polypharmacy, morbidity burden and patient complexity via indirect pathways. However, direct pathways showed unexpected associations between higher levels of multimorbidity and better safety. The consistent association between multimorbidity constructs and worse patient safety among women makes it advisable to target this group for the development of interventions, with particular attention to the role of comorbidity discordance. Further research, particularly qualitative research, is needed for clarifying the complex associations among men.

The Relationship

Bicultural identity orientations have rarely been examined in relation to both perceived discrimination and psychological distress. Furthermore, these constructs have usually been studied in isolation, but their intersection is essential for understanding intercultural relations in multicultural societies. Using cross-sectional data from 1,143 Canadian undergraduate students from immigrant families, this study explored the relationship between perceived discrimination and psychological distress, and how bicultural identity orientations might mediate this relationship. The structural equation modeling results indicated that perceived discrimination was associated with higher levels of psychological distress and hybrid, monocultural, alternating, and conflicted orientations, but lower levels of complementary orientation. Alternating and conflicted orientations were related to higher psychological distress, whereas the other orientations were not. Alternating and conflicted orientations mediated the relationship between perceived discrimination and psychological distress, whereas the other orientations did not. The findings are discussed in light of theories on identity integration, rejection–identification, and acculturation.

The Relationship

In light of increasing concerns about global environmental problems, environmental moral education is assumed to have a significant influence on the pro-environmental behaviour of students. Within the past decade, several higher education institutes have acknowledged the importance of integrating sustainability into the educational curriculum to have a focused and explicit impact on society. The current study investigated the relationship between environmental moral education and pro-environmental behaviour while drawing upon insights from the conservation of resource theory. The relationship among the aforementioned variables was studied for the mediating role of psychological empowerment and the moderating effect of Islamic religiosity. Data were collected from 429 university students with a cross-sectional approach. The data were analysed using “structural equation modelling” and “PROCESS” analytical techniques. The results of the study followed the predicted conceptual model, that is, environmental moral education was positively related to pro-environmental behaviour. Furthermore, psychological empowerment partially mediated the aforementioned relationship, while Islamic religiosity moderated the relationships between environmental moral education and pro-environmental behaviour as well as between environmental moral education and psychological empowerment. These findings reinforce the importance of environmental moral education and Islamic religiosity in understanding the Muslim student’s ecological behaviours.

Purpose The purpose of this paper is to examine the relationships between supplier development practices (SDPs) and supplier-buyer relationship practices from the supplier’s perspective (SBRSP), and seek to understand how specific SDPs may impact a buyer’s operational performance as well as supplier-buyer relationship practices. Design/methodology/approach The authors conducted a survey of 512 respondents from the different manufacturing firms in India and applied structural equation modelling to test a structural model that proposes the impacts of various efforts of SDPs on a buyer’s performance as well as SBRSP. Findings The study concludes that SDPs and SBRSP together improve the relationship between a buyer and supplier, and this improved relationship leads to competitive advantages (CAs) followed by profitability. Results indicate that supplier perspective of buyer-supplier relationship can be improved under the condition of SDPs and SBRSP together. SDPs are driven by productive measure and competitive pressure, whereas customer uncertainty is found to be statistically insignificant. Research limitations/implications The study was carried out in North Maharashtra Industrial Zone of India, where the auto sector and machine/components manufacturing firms have been established for a considerable period of time. Results of the study are limited to manufacturing organizations predominantly focussing on the automobile sector and machine/components manufacturing firms. Practical implications This study provides significant insights into the specific impact of various SDPs and SBRSP for both academics and practitioners. SDPs along with SBRSP practices lead to improvement in the relationship leading to CAs. SBRSP suggests that trust, long-term commitments and the supplier’s perspective are important practices for relationship improvement. Originality/value The current study attempts to identify what are the success factors for the supplier-buyer relationship from the supplier’s perspective and SDPs and how the supplier-buyer relationship can be improved under the condition of SDPs and SBRSP. Hence, the aim is to develop a more thorough understanding of the outcomes of a supplier-buyer relationship improvement from both buyer’s and supplier’s perspective, under the conditions of supplier development to achieve CAs leading to profitability. Furthermore, the study analyses the effect of the improved supplier-buyer relationship for achieving CAs leading to profitability.

Purpose The purpose of this paper is to investigate the relationship between employee motivation and intention for knowledge sharing behaviour. Inter-generational differences (generations X and Y only) were assumed to moderate in the relationship between intention and knowledge sharing behaviour of non-academic staff of higher learning institutions. This research also aims to test the role of behavioural intention as mediation between motivation and knowledge sharing behaviour. Design/methodology/approach This research tested a conceptual framework derived from widely accepted theories. This study was carried out on non-academic staff working at the different higher learning institutions in Malaysia. Respondents from private and public higher learning institutions in Peninsular Malaysia were asked to complete a self-administered questionnaire. This research also applied confirmatory factor analysis and structural equation modelling to examine the proposed hypothesis of this inquiry. Findings Results indicate that non-academic staff knowledge sharing behaviour was significantly mediated by intention between motivation and knowledge sharing behaviour relationship. More specifically, inter-generational differences (generations X and Y) play a significant moderation role between intention and knowledge sharing behaviour. Research limitations/implications The generalizability of this cross-sectional study can be strengthened by adopting a longitudinal approach in the next phase of the study. Practical implications The results of this research highlighted that the higher learning institutions need to institutionalize knowledge sharing behaviour among their non-academic staff (executive and non-executive) by facilitating knowledge sharing-oriented work environment. Originality/value This paper has attempted to furnish a comprehensive understanding of knowledge sharing behaviour among the non-academic staff of higher learning institutions.

Using Data

Using data on marijuana and cocaine use from the 1984 National Longitudinal Survey of Youth, the authors examine the hypothesis that drug use reduces labor market productivity, as measured by wages. From an analysis that controls for the probability of employment and the endogeneity of drug use, they find that although long-term and on-the-job use of marijuana negatively affected wages, the net productivity effect for all marijuana users (both those who engaged in long-term or on-the-job use and those who did not) was positive. No statistically significant association was found between cocaine use and productivity.
