Work-related use of information and communication technologies (ICTs) after hours can be potentially detrimental to employee well-being. In the current study, we examine whether psychological detachment mediates the link between work-related use of ICTs after hours and fatigue and whether affective commitment exacerbates this mediated relationship.

We collected two waves of data from 295 employees in Vietnam, with 51% being female and an average age of 37.81 years old (SD = 7.93).

Work-related use of ICTs after hours was positively related to employees' fatigue via psychological detachment. The negative relationship between work-related use of ICTs after hours and psychological detachment was stronger for employees with higher affective commitment.

Organizations are encouraged to set policies and procedures to reduce work-related use of ICTs after hours to protect employee health; when work-related use of ICTs after hours is necessary, organizations should provide employees, especially those with higher affective commitment, with resources and strategies to better detach from this experience.

Our findings contribute to the understanding of how work-related use of ICTs after hours might adversely affect employee well-being through psychological detachment and that more committed employees can be more affected in this process.

The support of host country nationals (HCNs) is a key determinant of expatriate adjustment and performance. The purpose of this paper is to explore underlying motivations for their support to expatriates. Previous research has shown that HCNs with pro-social motivation are more likely to help expatriates. Drawing upon motivated information processing in groups (MIP-G) theory, the authors test whether epistemic motivation moderates the observed relationship between pro-social motivation and HCNs’ support toward expatriates.

The authors ran two correlational studies (N = 267) in the USA (Study 1) and South Korea (Study 2). Across two studies, epistemic motivation and social motivation were measured using their multiple proxies validated in previous research. The authors also measured HCNs’ willingness to offer role information and social support to a hypothetical expatriate worker.

Results lend support to our hypotheses that pro-social HCNs are more willing than pro-self HCNs to provide role information and social support to the expatriates, but this occurs only when they have high rather than low epistemic motivation.

The current paper contributes the literature on HCNs helping expatriates by qualifying the prior results that a pro-social motivation (e.g. agreeableness and collectivism) increases the willingness of HCNs to help expatriates. As hypothesized, this study found that that case is only true when HCNs have high, rather than low, epistemic motivation. Also, previous research on MIP-G theory has mainly focused on the performance of small groups (e.g. negotiation, creativity and decision-making). To the best of the authors’ knowledge, this research is the first attempt to test MIP-G theory in the context of HCNs helping expatriates.

By adopting a cross-country analysis, this study aims to investigate how consumers' perception of book covers affects their online book purchases in terms of feelings of delight and perceived value of the book.

The authors tested the hypotheses using a structural equation model using two countries' datasets obtained from 191 Japanese and 207 French consumers.

The perceived attractiveness of a picture/photo on a book cover can positively influence feelings of delight. Such emotion enhances a book's perceived value, resulting in active online book purchases. Furthermore, when the perceived value of a book is evident, the French are more strongly motivated to purchase books compared to Japanese consumers.

By simultaneously examining emotion and perceived value as an organism, the authors advance the knowledge of the relationship between book covers and online book purchases. In addition, the authors offer evidence that cross-cultural differences (between the French and Japanese) can stimulate different responses to each affective and cognitive internal state, although similar environmental stimuli are provided.

This study investigates the effects of related and unrelated technology diversity on R&D efficiency and how a firm’s unique core technology moderates this relationship. In particular, this study aims to address the research gap in the technological diversity literature by examining whether the effects of related and unrelated technological diversity on R&D efficiency are consistent in the context of R&D-intensive firms.

Using a panel dataset of 516 top R&D investors worldwide from 2012 to 2018, the paper tests hypotheses on how the ambivalence of technological diversity affects R&D efficiency depending on the level of diversity.

Unrelated technological diversity has an inverted U-shaped curve relationship with R&D efficiency, which indicates that there exists an optimal point of unrelated technological diversity. Additionally, core technology plays a contingent role in this relationship by alleviating the volatility of the inverted U-shaped relationship between unrelated technological diversity and R&D efficiency.

This study makes an original contribution to the technological diversity literature by adopting an approach not limited to specific countries or industries, focusing on R&D-intensive contexts. Furthermore, the paper distinguishes the various types of technological diversity, considering that the motivations and strategic objectives underlying technological diversity vary depending on the specific type. This allows researchers to gain a deeper insight into how different types of diversity strategies impact R&D efficiency.

Drawing on the theory of planned behavior, this study aims to conduct an empirical investigation on whether and how psychological and motivational factors (i.e. attitudes, subjective norms and perceived behavioral control) affect actual purchase behavior. It does so through the lens of boycott intention and gender differences in the context of boycott campaigns.

Focusing on the South Korean boycott campaign against Japanese companies, this study employs a structural equation model using survey data from 571 South Korean consumers to test the hypotheses.

While the three psychological and motivational factors inhibit all three dimensions of actual purchase behavior (i.e. purchase frequency, number of items purchased and purchase amount) through increased boycott intention, perceived behavioral control of boycotts directly curb South Korean consumers from purchasing Japanese products. Additionally, the effect of boycott intention on overall actual purchase behavior is stronger for men than for women, suggesting a moderating role of gender.

To mitigate the devastating impact of unexpected consumers' boycott campaigns, this study advises that global brand management and attractive online channels are essential while considering the differential impact of gender.

By conceptualizing three dimensions of actual purchase behavior capturing behavioral changes before and after a boycott, this study highlights the linkages between psychological and motivational factors, intentions and behaviors. Additionally, this study attempts to clarify the previously conflicting evidence on gender's role in boycott campaigns while taking a culture-inclusive psychologies approach to gender.

This study identifies the factors that postgraduate service management programs (PSMPs) in Korean Universities can use to gain competitive advantage.

A mixed-method approach was adopted in serial order to verify the role of PSMP identity in the relationship between education service quality and student satisfaction established in prior research. Study 1 is a case study designed to gain a comprehensive understanding of the PSMPs in Korea using data derived through a document review of the sources collected from the official websites of PSMPs. In Study 2, focus group interviews were conducted with students and graduates of PSMPs to gain new insights that would help attain competitive advantage. Finally, a questionnaire survey was conducted in Study 3 to statistically test the relationship between PSMP identity, education service quality and student satisfaction.

Education service quality has a positive impact on PSMP identity, PSMP identity has a positive impact on student satisfaction and PSMP identity mediates the aforementioned impacts. The results established PSMP identity as a key factor in enhancing its competitiveness.

Since PSMPs have a short history and are limited number of cases in Korea, their justification is not well-understood by the general public and companies. This problem is not limited to PSMPs but is also shared by other specialized postgraduate programs. With comprehensive data on and new insights into PSMPs, including the determinants of competitive advantage, the results provide basic evidence for follow-up research and useful information for administrative officers in charge of specialized postgraduate programs.

The role of entrepreneurship education in promoting entrepreneurial actions remains unclear. The purpose of this paper is to investigate the logic of different types of entrepreneurship education and the effect of learning characteristics in promoting entrepreneurial actions among student entrepreneurs in the higher education setting.

The study employs a quantitative approach involving the use of survey data collected via an Internet tool. The constructs of variables are measured using previously tested scales. The data were analysed using partial least squares modelling because it can handle formative and reflective constructs in the same model and is capable of testing for moderation.

The findings illustrate that voluntary entrepreneurship education generates learning outcomes in terms of students' entrepreneurial actions, which is important because without action, a venture will never be launched. This is especially so if students show a deep learning orientation, while mastery motivation showed a significant and negative moderating effect. This is not the case for compulsory entrepreneurship education.

Embedded in construal level theory, this paper offers knowledge that can help to advance entrepreneurship education research (1) by uncovering the role of different types of entrepreneurship education interventions, (2) by considering students' entrepreneurial actions as the dependent variable and (3) by unravelling the role of students' learning characteristics in the efficacy of entrepreneurship education interventions. By doing this, the study addresses recent repeated calls for more fine-grained research focused on how university students learn in entrepreneurship in higher education and its effects.

The purpose of this paper is to analyze the spatial patterns of different phenomena in the same geographical space. Andresen’s spatial point pattern test computes a global index (the S-index) that informs on the similarity or dissimilarity of spatial patterns. This paper suggests a generalized S-index that allows perfect similarity and dissimilarity in all situations.

The relevance of the generalized S-index is illustrated with police data from the San Francisco Police Department. In all cases, the original S-index, its robust version – which excludes zero-crime areas – and the generalized alternative were computed.

In the first example, the number of crimes greatly exceeds the number of areas and there are no zero-value areas. A key feature of the second example is that most street segments were free of any criminal activity in both patterns. Finally, in the third case, one type of event is considerably rarer than the other. The original S-index is equal to the generalized index (Case 1) or theoretically irrelevant (Cases 2 and 3). Furthermore, the robust index is unnecessary and potentially biased when the number of at least one phenomenon being compared is lower than the number of areas under study. Thus, this study suggests to replace the S-index with its generalized version.

The generalized S-index is relevant for situations when events are relatively rare –as is the case with crime – and the unit of analysis is small but plentiful – such as addresses or street segments.

The purpose of this paper is to describe and test a quantitative harm-focused approach to offender selection for investigation and surveillance. The approach incorporates a measure of crime harm as well as a time-decay function that adjusts the score downward for offenders who desist from crime.

Across 10 of 21 high-crime police districts in the city of Philadelphia, the authors compare the mean harm scores of 60 prolific offenders selected by district analysts, 60 prolific offenders selected citywide by detectives assigned to the Gun Violence Reduction Task Force and the top 60 prolific offenders chosen from a harm-score generated list of known offenders in the ten high-crime districts.

The offenders on the harm-focused list have significantly greater mean harm scores than the offenders identified by the crime analysts or task force personnel. They have a significantly greater mean number of gun crime episodes in their offending history as well.

The harm-focused approach uses arrest data that may not accurately reflect convictions and which miss undetected criminal activity. A leader of a criminal organization who orchestrates criminal activities but does not engage directly may have a low harm score. Arrest data may also suffer from some inherent bias. The approach also requires the creation of a crime harm index. Determining the operational impact on overall crime reduction by focusing on offenders with higher harm scores will require further research.

Clinical methods of target selection based on officer intuition, opinion and experience may have limitations in terms of effectiveness and accuracy. They also lack transparency and may incorporate bias, a critical consideration given the current crisis in police-community trust and legitimacy. The actuarial method of weighing the harm of past offending with a crime harm score may be more acceptable and defendable to the community. It also identifies offenders with a higher frequency of involvement in gun crimes. Until methodological limitations are better understood, a compromise may be to start with the harm-score method (data-driven) and supplement this initial list through intelligence and investigative information.

The paper expands crime harm indices to quantify offender triage lists. The authors also empirically demonstrate through a case study that the approach is more effective at identifying harmful offenders than methods that solely rely on the experience or intuition of either crime analysts or detectives.
