Exploring the Moderating Roles of Perceived Person–Job Fit and Person–Organisation Fit on the Relationship between Training Investment and Knowledge Workers' Turnover Intentions

Previous studies have documented inconsistent results in terms of the relationship between knowledge workers' perceived training investment and their turnover intentions. In order to clarify the inconsistencies, the present study extends previous research by exploring the moderating roles of perceived demand–ability (D–A) job fit and person–organisation (P–O) fit. Data were collected from 303 research and development (R&D) engineers from 30 high‐technology firms in Taiwan. Hierarchical regression analyses were conducted to test the hypotheses. The results show that perceived D–A fit, P–O fit, and perceived training investment interact jointly to predict knowledge workers' turnover intentions. Specifically, while the main effect of perceived training investment on turnover intentions was negative, under situations of extremely high perceived D–A fit and extremely low P–O fit, the relationship between knowledge workers' perceived training investment and their turnover intentions became positive, and under situations of low perceived D–A fit and high P–O fit, the relationship between knowledge workers' perceived training investment and their turnover intentions remained negative. Theoretical and practical implications are also discussed. Les études antérieures ont donné des résultats contradictoires quant aux relations entre la connaissance que les salariés perçoivent de l’investissement dans la formation et leurs intentions de changer. Dans le but de clarifier ces incohérences, la présente étude prend la suite de recherches antérieures en explorant les rôles modérateurs de la compatibilité perçue entre la compétence et les nécessités au travail (DA) et de la compatibilité entre la personne prise dans sa globalité et les caractéristiques de l’organisation qui l’emploie (PO). Les données ont été collectées auprès de 303 ingénieurs en recherche et développement (R&D) de 30 entreprises de haute technologie à Taiwan. Des analyses de régression hiérarchique ont conduit à tester les hypothèses. Les résultats montrent que la compatibilité D‐A, la compatibilité P‐O et l’investissement perçu dans la formation interagissent conjointement pour prédire les intentions de changement des employés. Plus spécifiquement, alors que le principal effet de l’investissement perçu dans la formation sur les intentions de changement est négatif, dans des conditions de compatibilité D‐A perçue comme étant basse et de compatibilité P‐O haute, la relation entre la connaissance que les salariés perçoivent de l’investissement dans la formation et leurs intentions de changement reste négative. Les implications théoriques et pratiques sont aussi discutées.

Am I the Only One This Supervisor is Laughing at? Effects of Aggressive Humor on Employee Strain and Addictive Behaviors

Prior literature on humor primarily documents its positive effects on employees’ attitudes and behaviors, though increasing research on aggressive humor suggests some conflicting viewpoints. This paper proposes a model based on social comparison and attribution theories to examine the influence of supervisors’ aggressive humor on employees’ strain and addictive behaviors. The tests of the research model entailed a 2‐wave study with 243 frontline employees from 4 manufacturing companies of a group corporation in China. The results showed that supervisors’ aggressive humor with employees related positively to employees’ strain. This positive association became stronger when the supervisors did not use aggressive humor with the peers of the focal employees. Employees’ strain mediated the interactive effects of supervisors’ aggressive humor with the focal employees and those with their peers on employees’ addictive behaviors (e.g., problematic use of Internet, alcohol, and tobacco). As well as having practical implications, this study offers theoretical insights for research into humor, leadership, and addictive behaviors.     

Culture, temporal focus, and values of the past and the future

This article examines cultural differences in how people value future and past events. Throughout four studies, the authors found that European Canadians attached more monetary value to an event in the future than to an identical event in the past, whereas Chinese and Chinese Canadians placed more monetary value to a past event than to an identical future event. The authors also showed that temporal focus-thinking about the past or future-explained cultural influences on the temporal value asymmetry effect. Specifically, when induced to think about and focus on the future, Chinese valued the future more than the past, just like Euro-Canadians; when induced to think about and focus on the past, Euro-Canadians valued the past more than the future, just like Chinese.     

Friction and wear behaviour of Inconel 718 alloy fabricated by selective laser melting after heat treatments

ABSTRACT

The effect of heat treatments (solution and double aging) on friction and wear behaviour of Inconel 718 (IN718) alloy fabricated by selective laser melting (SLM) were studied. After heat treatment of solution and double aging, the friction and wear of the alloy have been improved. The worn surfaces of heat-treated IN718 alloy became smoother, and micro-ploughing became shallower. After solid solution hearting, a portion of the Laves phase ((Ni, Fe, Co)₂(Nb, Ti, Mo)) dissolves into the matrix, after which the γ″ phase (Ni₃Nb) andthe equilibrium phase of the δ phase (Ni₃Nb) precipitates during double ageing. After solution and double aging, nano-scale γ′ (Ni₃(Al, Ti)) and γ″ phases distribute homogeneously in the matrix, which improves the material hardness and wear resistance of the SLMed IN718 alloy.     

An Extension of Dominance Analysis to Canonical Correlation Analysis

Dominance analysis (Budescu, 1993 Budescu, D. V. 1993. Dominance analysis: A new approach to the problem of relative importance of predictors in multiple regression.. Psychological Bulletin, 114: 542–551. [Crossref], [Web of Science ®] , [Google Scholar]) offers a general framework for determination of relative importance of predictors in univariate and multivariate multiple regression models. This approach relies on pairwise comparisons of the contribution of predictors in all relevant subset models. In this article we extend dominance analysis to canonical correlation analysis to explore the relative importance of the variables in both sets. The proposed extension provides (a) a decomposition of the models' fit into components associated with the individual variables; (b) the ability to compare the relative importance of variables from the two sets; (c) the ability to perform multistage analyses, involving all canonical variates; and (d) a bootstrapping inference procedure. The approach is illustrated with an empirical data example involving parenting styles and youth outcomes and its unique features are highlighted and discussed.     

Psychological contracts and innovative behavior: a moderated path analysis of work engagement and job resources

This study explored the relationships between psychological contract types and innovative behavior. We focused on the mediating effect of work engagement and the moderating effect of job resources (organizational and social resources). Participants were 267 dyads of research and development engineers and their supervisors from 30 high‐tech companies. Moderated path analysis was used to test the hypotheses. Findings showed that: (a) work engagement fully mediated the negative relationship between transactional contracts and innovative behavior; in addition, it also fully mediated the positive relationship between relational contracts and innovative behavior; and (b) job resources attenuated the former and strengthened the latter mediating effects. These findings contribute to understanding how, why, and when psychological contract types lead to innovative behavior via work engagement.     

Methods for Mediation Analysis with Missing Data

Despite wide applications of both mediation models and missing data techniques, formal discussion of mediation analysis with missing data is still rare. We introduce and compare four approaches to dealing with missing data in mediation analysis including listwise deletion, pairwise deletion, multiple imputation (MI), and a two-stage maximum likelihood (TS-ML) method. An R package bmem is developed to implement the four methods for mediation analysis with missing data in the structural equation modeling framework, and two real examples are used to illustrate the application of the four methods. The four methods are evaluated and compared under MCAR, MAR, and MNAR missing data mechanisms through simulation studies. Both MI and TS-ML perform well for MCAR and MAR data regardless of the inclusion of auxiliary variables and for AV-MNAR data with auxiliary variables. Although listwise deletion and pairwise deletion have low power and large parameter estimation bias in many studied conditions, they may provide useful information for exploring missing mechanisms.     

Outlying Observation Diagnostics in Growth Curve Modeling

Growth curve models are widely used for investigating growth and change phenomena. Many studies in social and behavioral sciences have demonstrated that data without any outlying observation are rather an exception, especially for data collected longitudinally. Ignoring the existence of outlying observations may lead to inaccurate or even incorrect statistical inferences. Therefore, it is crucial to identify outlying observations in growth curve modeling. This study comparatively evaluates six methods in outlying observation diagnostics through a Monte Carlo simulation study on a linear growth curve model, by varying factors of sample size, number of measurement occasions, as well as proportion, geometry, and type of outlying observations. It is suggested that the greatest chance of success in detecting outlying observations comes from use of multiple methods, comparing their results and making a decision based on research purposes. A real data analysis example is also provided to illustrate the application of the six outlying observation diagnostic methods.     

辩证法心理学发展的曲折道路与新机遇

当前国际上所兴起辩证法心理学研究的热潮对于克服当代心理学的深层困境,推动理论心理学研究与重建心理学理论具有重要意义。然而辩证法心理学的发展道路并不平坦,其根源在于以下事实:1)科学实证主义的"无矛盾"原理与辩证法是格格不入的;2)当代辩证法心理学理论并不是完美的,其本身还存在弊端。当今由于社会建构论的兴盛与理论心理学的复兴为辩证法心理学的发展又提供了新的机遇。
