Abstract
This study compares minimum‐extended Gini hedge ratios estimated by the rank‐based method of Lerman and Yitzhaki and a nonparametric kernel method. The rankbased method is more prevalent in the Gini hedging literature, however, the kernel estimator provides a more powerful approach to estimation. The empirical results show that the hedge ratios calculated using these two methods are different for all levels of risk aversion, and that rank‐based hedge ratios are typically larger than those estimated using the kernel method. Moreover, the differences tend to be larger at moderate and high levels of risk aversion and smaller at lower levels. Statistical evidence shows that the hedge ratios are highly statistically different for three of the five commodities tested. However, despite these differences, we find no differences in hedging performance.

Abstract
This paper compares the hedging performance of the minimum‐extended Gini hedge ratio (MEGHR) and the minimum‐variance hedge ratio (MVHR) using three emerging market currencies. The MEGHR is consistent with the expected utility hypothesis under very general conditions, unlike the MVHR which requires special distributional assumptions. Our sample violates these conditions, and thus provides a context for contrasting the performance of the MEGHR and MVHR. Our results show that the MVHR and MEGHR are indeed different and in some cases the differences are substantial, both statistically and in order of magnitude. This indicates that the MEGHR should provide superior hedging performance given its theoretical robustness. Our hedging performance results support this conclusion for all currencies.

Abstract
This paper presents a framework consisting of seven logically linked considerations yielding nine strategies for managing risky situations. The framework provides a comprehensive method any entity can use to determine its strategy for managing a risky situation. The framework goes beyond the issue of calculating risk to asking how it might be managed The framework is applied in an example involving a human resources manager making a series of three related choices. It is also applied to the choices of strategies for a chief financial officer facing currency rate fluctuations and excessive taxes on profit.

Abstract
Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Abstract
Purpose
Many individuals in drug treatment courts (DTCs) have co-occurring mental health and substance use disorders (COD), which can negatively impact treatment engagement, behavioral health and criminal justice outcomes. This paper aims to report results of DTC participants with a COD, who received a 12-month wraparound treatment intervention called MISSION-Criminal Justice (MISSION-CJ) alongside DTC to improve treatment engagement and behavioral health outcomes and reduce reincarcerations.
Design/methodology/approach
In this pre-post, single-group pilot, 48 clients enrolled and 81% completed 12-month follow-up assessments (N = 39) and weekly MISSION-CJ fidelity for type and intensity of services delivered. Generalized linear mixed models (GLMMs) were computed with a fixed term for fidelity (e.g. high or low MISSION-CJ), time and a fidelity x time interaction term.
Findings
Among participants, at 12 months, 81% of the participants remained engaged in treatment at study completion, and 89% had high MISSON-CJ fidelity. Clients demonstrated significant reductions from baseline to 12 months in average nights in jail (B = −0.1849511, p < 0.0344), mental health symptoms via the Behavior and Symptom Identification Scale (BASIS) total and subscale scores (B = −0.121613, p < 0.0186) and trauma symptoms on the PTSD Checklist-5 (PCL-5) (B = −0.928791, p < 0.0138). High MISSION-CJ fidelity further improved criminal justice, and behavioral health outcomes.
Originality/value
This was the first reported 12-month MISSION-CJ trial. While feasible to implement, given the design limitations, future research should include a large randomized controlled trial.

Abstract
This paper proposes an anthropology‐based theoretical model describing the impact of top management culture clash on the commitment of the acquired team to the new organization and on its cooperation with the acquiring team. It suggests that three factors are influential, namely the degree of cultural differences, the nature of the contact between the teams, and the intended level of integration between the companies. The paper generates numerous propositions for predicting the impact of the culture clash. It also offers suggestions for further theoretical and empirical study, and presents some of the model's practical implications.

Abstract
Ineffective expatriate performance and premature returns have been found to relate primarily to an inability to adjust to the foreign environment rather than a lack of technical competence. Research has identified three dimensions of expatriate adjustment: adjustment to work, adjustment to interactions with people in the foreign country and general adjustment to the culture and living conditions. Five major factors that have been found to influence these dimensions of adjustment and research using these factors provides a framework to help international firms understand and take a more active role in facilitating expatriate adjustment.

Abstract
Purpose
The purpose of this paper is to examine relationships between cross-cultural adjustment and stress of expatriate employees with families in a multinational corporation and identify common stressors reported during international transitions.
Design/methodology/approach
This study utilized both quantitative and qualitative methods through an online survey based tool. The CernySmith Assessment captured the statistical measures of objective adjustment scales along with written in, subjective stressor responses from a sample of expatriates.
Findings
Overall subjective stress level was negatively correlated with all five objective adjustment domains (organizational, cultural, relational, behavioral, and personal). Seven stressor categories (cultural, occupational, relational, historical, crisis, spiritual, physical) demonstrated statistically significant negative relationships with overall adjustment. Regression analysis indicated expatriate adjustment was predicted by spiritual, occupational, and support stressors. Write-in stressor responses provided specific expressions of individual stress challenges, strains, and hassles that support predicted relations according to the Family Adaptation and Adjustment Response model.
Research limitations/implications
This study provides a snapshot of objective adjustment interacting with subjective stress for expatriate employees from a single international organization during a specific time period.
Originality/value
These findings provide insights to organizations and human resource development professionals as well as to expatriates and their families on how stress impacts expatriate adjustment. It also highlights the need for support mechanisms to ease transitions and reduce stressors.
