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.     

现代逻辑的抽象化趋势——概述抽象代数逻辑的产生和发展

现在的逻辑学已发展为内容丰富、分支众多的学科。随着研究成果的日益丰富,逻辑学向更抽象化的方向发展成为必然,抽象代数逻辑就是这种趋势下产生的一种逻辑形态。要了解这种逻辑的产生,就要从现代逻辑的两个研究方法———对逻辑进行代数化处理和使推理概念形式化或符号化——     

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.     

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.     

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。     

心理学文化转向中的方法论难题及整合策略

近20多年来心理学的文化转向研究基本上扫清了许多外围障碍,但也暴露出了一些深层次的发展难题,如心理学的文化研究在实现科学观的转变过程中如何避免限制与泛化之问的矛盾：人类文化心理的普适性与差异性关系难以在实践操作层面上得到有效实现;后现代及全球化文化背景下加剧了心理学的对立与分歧。求得这一难题有效解决之关键在于改变滞后的科学观．深化阐述性与规范性心理文化层面研究的理论力度。     

全膝关节置换术后镇痛策略

安全、有效的术后镇痛是全膝关节置换术（total knee replacement,TKR）后各项功能恢复的有力保证,与术后很长一段地间内患者的生活质量息息相关。目前关于TKR术后镇痛策略有多种形式和方法。外周神经阻滞和硬膜外镇痛（epidural control analgesia,CEA）的效果可靠,而外周神经阻滞的术后并发症更少,更为理想。
