Expatriates’ success in Ethiopia: Empirical evidence on the overlooked impact of cultural value alignment

The present study assessed the impact on the work engagement of expatriates’ personal value orientation alignment with the host country’s national culture. Participants were 231 expatriates from seven countries who are working in Ethiopia (females = 17%; mean age = 36 years, SD = 2.72 years). The expatriates completed measures of personal value orientation, cross-culture adjustment, and work engagement levels. Structural equation modelling analysis indicated expatriates with personal value orientations that align with the host country’s national culture to have a higher work engagement level. Cross-cultural adjustment mediated the relationship between personal value orientation and work engagement. Expatriates’ personal value orientation fit with the host country’s national culture is a resource to accomplish their work successfully.     

Abstract: Sample Size Planning for Latent Curve Models

When designing a study that uses structural equation modeling (SEM), an important task is to decide an appropriate sample size. Historically, this task is approached from the power analytic perspective, where the goal is to obtain sufficient power to reject a false null hypothesis. However, hypothesis testing only tells if a population effect is zero and fails to address the question about the population effect size. Moreover, significance tests in the SEM context often reject the null hypothesis too easily, and therefore the problem in practice is having too much power instead of not enough power.

An alternative means to infer the population effect is forming confidence intervals (CIs). A CI is more informative than hypothesis testing because a CI provides a range of plausible values for the population effect size of interest. Given the close relationship between CI and sample size, the sample size for an SEM study can be planned with the goal to obtain sufficiently narrow CIs for the population model parameters of interest.

Latent curve models (LCMs) is an application of SEM with mean structure to studying change over time. The sample size planning method for LCM from the CI perspective is based on maximum likelihood and expected information matrix. Given a sample, to form a CI for the model parameter of interest in LCM, it requires the sample covariance matrix S, sample mean vector , and sample size N. Therefore, the width (w) of the resulting CI can be considered a function of S, , and N. Inverting the CI formation process gives the sample size planning process. The inverted process requires a proxy for the population covariance matrix Σ, population mean vector μ, and the desired width ω as input, and it returns N as output. The specification of the input information for sample size planning needs to be performed based on a systematic literature review. In the context of covariance structure analysis, Lai and Kelley (2011) discussed several practical methods to facilitate specifying Σ and ω for the sample size planning procedure.     

Effects of Accuracy Motivation and Anchoring on Metacomprehension Judgment and Accuracy

The current research investigates how accuracy motivation impacts anchoring and adjustment in metacomprehension judgment and how accuracy motivation and anchoring affect metacomprehension accuracy. Participants were randomly assigned to one of six conditions produced by the between-subjects factorial design involving accuracy motivation (incentive or no) and peer performance anchor (95%, 55%, or no). Two studies showed that accuracy motivation did not impact anchoring bias, but the adjustment-from-anchor process occurred. Accuracy incentive increased anchor-judgment gap for the 95% anchor but not for the 55% anchor, which induced less certainty about the direction of adjustment. The findings offer support to the integrative theory of anchoring. Additionally, the two studies revealed a “power struggle” between accuracy motivation and anchoring in influencing metacomprehension accuracy. Accuracy motivation could improve metacomprehension accuracy in spite of anchoring effect, but if anchoring effect is too strong, it could overpower the motivation effect. The implications of the findings were discussed.     

面孔识别过程中多重社会亚范畴的交互作用

认知者往往依据陌生个体面孔所携带的性别、年龄、种族等多重社会范畴信息对其进行加工,以期快速识别和了解他人。在基于面孔识别的多重社会范畴加工过程中,亚范畴间存在着复杂的交互作用。研究者分别采用"Who Said What"范式、重复启动范式、加纳选择注意范式、鼠标追踪范式等方法,发现亚范畴间的内隐加工具有彼此削弱的特性,外显加工存在交互影响的不对称性和偏差性。动态交互理论对此进行了进一步的理论分析与阐释。今后需更加科学地区分社会范畴加工的各个阶段,凸显内隐和外显加工的区别与联系;同时进一步整合各研究范式,克服方法异质导致的结果偏差甚至矛盾。     

Microstructural characterization of the M23C6 carbide in a long-term aged Ni-based superalloy

The microstructural features of M₂₃C₆ carbide in a long-term aged heat- and corrosion-resistant Ni-based superalloy have been investigated in detail using various kinds of transmission electron microscope (TEM) techniques. It is found that TEM contrast, which is related to structural and chemical inhomogeneities inside the grains, always exists in the interior of grains in the alloy. The structure of these inhomogeneous regions has been determined to be the same as that of the γ′ and t-M₂₃C₆ phases, where t-M₂₃C₆ indicates a transitional and metastable phase. Although possessing the same structure as the M₂₃C₆ phase, the chemical composition of the t-M₂₃C₆ is different from that of the M₂₃C₆ phase. Compared with M₂₃C₆, t-M₂₃C₆ is richer in Ni, Co, Al and Ti but poorer in W, Mo and Cr. This phenomenon of structural and chemical inhomogeneity demonstrates that pristine M₂₃C₆ carbide (p-M₂₃C₆) precipitated in standard heat-treated samples is unstable. Therefore, upon long-term ageing treatment, Ni, Co, Al and Ti may locally enrich inside the p-M₂₃C₆ phase, finally forming the γ′ phase, which can be described by the decomposition reaction p-M₂₃C₆ → M₂₃C₆ + γ′.     

The role of formal information sharing in key account team effectiveness: does informal control matter and when

Team selling is a useful approach for retaining strategically important accounts in business-to-business markets. For key account sales teams, ensuring adequate access to information about customer needs offers sustainable competitive advantages. However, the internal alignment of market information remains a recurring managerial issue in key account team selling. This study develops a moderated mediation model to identify management strategies that encourage team members' formal information sharing, which in turn improves team effectiveness. Analysis of a multilevel data set comprising 37 fluid key account teams reveals that customer orientation and task interdependence increase formal information sharing among team members. Managers' exercise of professional control strengthens the positive impact that formal information sharing has on team satisfaction. However, the practice has a dysfunctional influence on the positive effect of task interdependence on formal information sharing. Firms with key account management (KAM) programs must decide whether the marginal benefits attained by advocating such professional control outweigh the possible drawbacks.

采用2(组内变量:量尺大小(25分和9分))×2(组间变量:评分方法(相对和绝对))的混合实验设计探讨评分量表对115名大学生新手评委评分准确性的影响。对于评分准确性,采用Cronbach1955年提出的四个指标,Elevation(EL)、Differential elevation(DE)、Stereotype accuracy(SA)、Differential Accuracy(DA)。结果发现,评分方法只在SA上主效应显著,量尺大小在只在DA上主效应边缘显著,评分方法和量尺大小在DE、SA和DA三个指标上均有交互作用。总体上看,在结构化面试评分中,对于评分准确性,相对评分量表优于绝对评分量表,小量尺量表优于大量尺量表。     

Psychometric properties of the Padua Inventory in Chinese college samples

The aim of the present study was to investigate the psychometric properties of the Padua Inventory in Chinese college samples. Three different samples (N1 = 1,939, N2 = 1,341, and N3 = 298) of Chinese college students were recruited. Exploratory factor analyses yielded a four-factor structure which was similar to that found in previous studies. Further, present results showed good internal consistency as well as convergent and divergent validity with the subscales of the Symptom Checklist-90 and the Penn State Worry Questionnaire. Although no sex difference was found on total score, women had significantly higher scores on Factor 2 (Urges and worries of losing control over motor behaviors) and Factor 4 (Checking), while men had significantly higher scores on Factor 3 (Contamination). Implications of ter the results and directions for research are discussed.
