Immersive virtual reality (IVR) has been frequently proposed as a promising tool for learning. However, researchers have commonly implemented a plethora of design elements in these IVR systems, which makes the specific aspects of the system that are necessary to achieve beneficial outcomes unclear. Against this background, this study aims to combine the literature on presence with learning theories to propose that the ability of IVR to present 3D objects to users improves the presence of these objects in the virtual environment compared with 2D objects, leading to increased learning performance.

To test this study’s hypotheses, the authors conducted a 2 (training condition: approach vs avoid) x 2 (object presence: high vs low) between-subjects laboratory experiment that used IVR with 83 female participants.

The results support this study’s hypotheses and show that training with high object presence leads to greater reactions to cues (chocolate cravings) and improved health behaviour (chocolate consumption).

This study shows that increased object presence leads to unique experiences for users, which help reinforce training effects. Moreover, this work sheds further light on how immersive computer technologies can affect user attitudes and behaviour. Specifically, this work contributes to IVR research by showing that learning effects can be enhanced through an increased degree of object presence.

The ethics literature has focused on the influence of self-construal dimensions on unethical decision-making. However, the literature is unclear about why these self-construal dimensions (Independent-self, Relational-self, Collective-self) impact differently on unethical decision-making. Based on the theory of cooperation and competition, this study empirically examines the mediating role of competitive orientation and addresses the theoretically unexplained question of why self-construal dimensions influence differently on unethical decision-making.

Based on the deductive approach, a quantitative research study was conducted on the Sri Lankan banking industry because there have been many instances of unethical behavior reported in this sector lately. Data were collected from 305 bank branch managers using a structured survey questionnaire.

The findings revealed that competitive orientation mediates the self-construal dimensions and explained that competitive orientation is one reason why independent-self, relational-self and collective-self influence differently on unethical decision-making.

This paper addresses the unanswered question of why self-construal dimensions relate to unethical decision-making differently.

This study aims to develop a reliable and valid German/Deutsch version of the management standards indicator tool (MSIT-D) to broaden the pool of instruments available to practitioners and to support international collaborations regarding this workplace management issue.

The MSIT-D was translated from English to German, then its psychometric properties examined using data from British employees (n = 321) and German employees (n = 358). Confirmatory factor analyses (CFAs) were used to evaluate the internal structure and measurement invariance, and Cronbach’s alpha was used to assess internal consistency. Comparisons were made with the German language risk assessment tool Fragebogen zur Gefährdungsbeurteilung psychischer Belastungen (FGBU) to examine concurrent and incremental validity. Criterion validity was checked using established measures of work-related health.

The MSIT-D has an equivalent seven-factor structure (demands, control, managerial support, peer support, relationships, role and change) as the original; the analyses confirmed configural and metric measurement invariance with the original scale. The internal consistency of the scales ranged from 0.82 to 0.91. Regarding criterion validity, the MSIT-D was positively correlated with emotional exhaustion and psychosomatic complaints and negatively correlated with work engagement and workability. The analyses yielded meaningful correlations between the MSIT-D dimensions and the FGBU.

This is the first study to develop a German version of the MSIT and confirm metric measurement invariance. This will allow a comparison of MSIT scores with related constructs between German- and English-speaking samples. As a reliable and valid instrument for assessing work-related stressors, the outcome of this study presents opportunities for developing a unified surveillance system for work-related stress at the European level.

The present article deals with the topic of migrants’ exclusion from welfare benefits in European host countries from the angle of the research on the so-called “welfare chauvinism” (Andersen and Bjørklund 1990, p. 212). More specifically, it explores the political justifications behind welfare chauvinism in the policy debate surrounding some recent chauvinist-oriented social policies. Drawing on that, the article develops a theoretical argument to generate expectations about how politicians use different types of justifications. The fundamental proposition is that the chauvinistic arguments used are shaped by the different types of social programs, i.e. either universal or means-tested programs.

Qualitative content analysis of several selected parliamentary debates in the period 2017–2019 in Austria is carried out. In order to improve the efficiency of the research, the author relies on MAXQDA, an advanced piece of software for qualitative data analysis, to code the qualitative data and analyze them. The author prefers this to other similar programs as it is considered a valid and reliable tool within the academic research world.

The article points out that programs design works as an explanatory factor to highlight variations of welfare chauvinist arguments.

It develops for the first time a theoretical argument explaining the presence and variation of welfare chauvinist arguments based on social programs design.

Background: Geostatistics focuses on spatial or spatiotemporal datasets. Geostatistics was initially developed to generate probability distribution predictions of ore grade in the mining industry; however, it has been successfully applied in diverse scientific disciplines. This technique includes univariate, multivariate, and simulations. Kriging geostatistical methods, simple, ordinary, and universal Kriging, are not multivariate models in the usual statistical function. Notwithstanding, simple, ordinary, and universal kriging techniques utilize random function models that include unlimited random variables while modeling one attribute. The coKriging technique is a multivariate estimation method that simultaneously models two or more attributes defined with the same domains as coregionalization.

Objective: This study investigates the impact of populations on traffic volumes as a variable. The additional variable determines the strength or accuracy obtained when data integration is adopted. In addition, this is to help improve the estimation of annual average daily traffic (AADT).

Methods procedures, process: The investigation adopts the coKriging technique with AADT data from 2009 to 2016 from Montana, Minnesota, and Washington as primary attributes and population as a controlling factor (second variable). CK is implemented for this study after reviewing the literature and work completed by comparing it with other geostatistical methods.

Results, observations, and conclusions: The Investigation employed two variables. The data integration methods employed in CK yield more reliable models because their strength is drawn from multiple variables. The cross-validation results of the model types explored with the CK technique successfully evaluate the interpolation technique's performance and help select optimal models for each state. The results from Montana and Minnesota models accurately represent the states' traffic and population density. The Washington model had a few exceptions. However, the secondary attribute helped yield an accurate interpretation. Consequently, the impact of tourism, shopping, recreation centers, and possible transiting patterns throughout the state is worth exploring.

The initial policy of the countries that developed vaccines has been to lock the vaccine by patent. This has been due to the fact that domestic demand for vaccine was mounting. Since only a few countries could invest in it, manufacturing and export remained at the behest of those few resulting in deep inequity in the global rollout. Pandemics are global health crises. Hence, calls for the patent waiver for the COVID-19 vaccine are growing to access the vaccine. The vaccine and its production, marketing and distribution have been politicized driven by the hegemonic aspiration. Both manufacturing and import-dependent countries are racing to win the diplomatic battle: the former has to win to gain hegemony and the latter to get the vaccine. Hence, the vaccine distribution has been marked with deep discrimination, and as a result, the migrant community is less likely to get their vaccine on time. This article engages in the decades-long debate over intellectual property rights and patenting life-saving vaccines. We argue that exemption of COVID-19 vaccines from intellectual property rights would improve global access and equity.

Family constitutions are relatively new to the law of family companies, although there might have been forerunners in the history of entrepreneur families. The practical importance and the proliferation of family constitutions in German family companies are increasing, along with the discussion of family constitutions in legal literature. This new instrument of family governance is not law driven but business driven, it has been designed by business advisors. Its analysis and classification are still at the very beginning in academic research and practice. Even though family constitutions are generally deemed to be without any legal effect and not legally binding, from a legal point of view, this assumption is at least highly questionable.

Compared to the years prior to the COVID-19 pandemic, more workers today seemingly have choice over where, when and how they do their work. However, gender inequalities at work and at home persist, which may impact perceptions of choice. Thus, researchers must investigate the potential impact of gender and domestic responsibilities on perceptions of work-related options, including perceptions of workspace choice.

Using an original dataset with workers in North America, South America, Europe and Asia (N = 3,147), the authors conducted logistic regression analyses to explore whether workers felt they had a choice in where they do their work (workspace choice). In addition to gender, the authors considered the effect of domestic responsibilities (childcare and housework) on worker perceptions of workspace choice.

In the paper's initial regression, the authors found that men (OR: 1.24; 95%CI 1.04–1.48) as well as workers reporting that a partner was responsible for all or most of the housework (OR: 1.80; 95%CI 1.34–2.40) and childcare (OR 1.51; 95%CI 1.09–2.09) reported feeling a greater sense of workspace choice. Simultaneously, follow-up regression analyses found that women and men whose partners had a greater share of domestic responsibility had amplified perceptions of choice. However, surprisingly, men who claimed primary responsibility for domestic work also reported more choice over workspace.

Using an international sample, the authors explore gender inequities in worker perceptions of workspace choice. The authors' findings suggest that domestic responsibilities interact with gender in interesting ways, leading to differences in perceptions of choice in the post-pandemic workplace.

This paper aims to examine the influence of the interplay between servant leadership behaviors and Machiavellianism on leader effectiveness.

Drawing on trait activation theory and motivation to lead theory, the authors hypothesize that the effect of servant leadership behaviors on perceived leadership effectiveness is manifested differently in teams with high-Machiavellian vs. low-Machiavellian leaders. In teams with low-Machiavellian leaders, servant leadership behaviors are expected to be associated with a cooperative way of handling team conflicts, which enhances employees' leader effectiveness ratings. In contrast, in teams with high-Machiavellian leaders, this mediation role vanishes due to the incongruency between Machiavellian traits and the cooperative context. The authors conducted a two-wave survey-based study and tested the hypotheses with a matched supervisor-employee sample from 310 employees and their leaders in 91 teams.

The results showed that servant leadership behaviors positively impact leadership effectiveness and that this effect takes place through cooperative team conflict management (TCM) without controlling for leaders' Machiavellian trait. Further analysis shows this mediation mechanism is only strong and significant in teams led by low-Machiavellian leaders, but not high-Machiavellian leaders.

To the authors’ best knowledge, this is the first study that examines the interplay of servant leadership behaviors and Machiavellianism on perceived leader effectiveness.

本文旨在探討僕人式領導行為與馬基雅維利主義之間的相互作用會如何影響領導效能。

我們根據特質激活理論和領導動機理論、建立了一個假設，這個假設就是： 僕人式領導行為對感知的領導效能所產生並顯示出來的影響、是會視乎團隊是高/強馬基雅維利主義，還是低/弱馬基雅維利主義而有所分別的。若團隊的領導者是低/弱馬基雅維利主義的話，僕人式領導行為大概會與使用合作的方式去處理團隊衝突有相互之關聯，這會提高僱員對領導效能的評分。與此相反，若團隊的領導者是高/強馬基雅維利主義的話，這調節作用和角色將會因馬基雅維利主義的特質與合作的環境之間存在著不協調而消失。我們進行了一個兩波的、以及基於調查的研究，在這研究中，我們利用管理者和員工相應的樣本來測試各個假設;這些樣本包括91個團隊內的310名員工及其領導者。

研究結果顯示、僕人式領導行為對領導效能會產生積極的影響，而這影響是透過以合作方式管理團隊衝突而產生的，亦沒有對領導者的馬基雅維利主義特質加以管控。我們進一步的分析顯示、這調節機制只會在由低/弱馬基雅維利主義的領導者領導的團隊內顯得強烈和顯著，但若領導者是高/強馬基雅維利主義的話，情況就不一樣了。

盡我們所知，本研究為首個研究、去探討僕人式領導行為與馬基雅維利主義之間的相互作用會如何影響感知的領導效能。
