The correlations between mechanical behaviour, tensile strength, and rock parameters of metasedimentary rock samples in Karak, Pahang’s New Austrian Tunnelling Method (NATM) were statistically evaluated from the rock mechanic laboratory works at the selected sections around 2,000 m of the tunnel (named as NATM-1). According to a statistical analysis, lithotypes, geological structures, and region geology have a significant impact on the mechanical behaviour of the metasedimentary rock. In the Brazilian test, the fracture behaviour of the disc specimens was highly related to the reliability and precision of the experimental data by validations of methods. In this work, the impact of different loading methods and rock lithotypes on the failure mechanism of Brazilian discs was examined utilising five different metasedimentary rock types and three different loading methods. During the loading operation, the strain and displacement fields of the specimens were recorded and evaluated using a computerised strain gauge system. The rock types, according to experimental data, have a significant impact on the peak load and deformation properties of Brazilian discs. With the method below, tensile strength point of a disc specimen is clearly regulated by the material stiffness and tensile–compression ratio. Seismic occurrences have had a substantial impact on changing the rock and exerting forces that may affect its mechanical characteristics as well as its vulnerability to weathering effects or discontinuities. As a result, the goal of this study is to look into the connection between rock mechanics and metasedimentary rock stress analysis in NATM-1, Karak, Pahang.

Global virtual teams (GVTs), also known as transnational or distributed teams, are increasingly common as organizations strive to maintain a global presence, find top and diverse talent, and cope with economic constraints. Despite increasing adoption of GVTs, there is a dearth of research addressing whether GVTs are an effective coping strategy for dealing with the world economic crisis and if there are unintended negative consequences on employee well-being as a result of their use. Thus, a focal question guiding the development of this chapter is whether or not GVTs are a sustainable solution for organizations? In this chapter we present a generic framework depicting the cycle by which macroeconomic demands impose changes on organization's structures, which trickle down to the level of the individual who has to cope with the demands the new structure has imposed. We discuss GVTs as an intervention (or cure) for organizations’ dealing with the current world economic crisis and how this organizational intervention inevitably becomes the context (or cause) for the kinds of stressors or demands employees face.

This study applies asymmetric rather than conventional symmetric analysis to advance theory in occupational psychology. The study applies systematic case-based analyses to model complex relations among conditions (i.e., configurations of high and low scores for variables) in terms of set memberships of managers. The study uses Boolean algebra to identify configurations (i.e., recipes) reflecting complex conditions sufficient for the occurrence of outcomes of interest (e.g., high versus low financial job stress, job strain, and job satisfaction). The study applies complexity theory tenets to offer a nuanced perspective concerning the occurrence of contrarian cases – for example, in identifying different cases (e.g., managers) with high membership scores in a variable (e.g., core self-evaluation) who have low job satisfaction scores and when different cases with low membership scores in the same variable have high job satisfaction. In a large-scale empirical study of managers (n = 928) in four (contextual) segments of the farm industry in New Zealand, this study tests the fit and predictive validities of set membership configurations for simple and complex antecedent conditions that indicate high/low core self-evaluations, job stress, and high/low job satisfaction. The findings support the conclusion that complexity theory in combination with configural analysis offers useful insights for explaining nuances in the causes and outcomes to high stress as well as low stress among farm managers. Some findings support and some are contrary to symmetric relationship findings (i.e., highly significant correlations that support main effect hypotheses).

In 2020, household incomes were severely hit by the lockdowns imposed across the world in response to the COVID-19 pandemic. Using data from the last available wave of the euro-area harmonized Household Finance and Consumption Survey for 2016, this chapter documents European households’ financial resilience to this shock, based on pre-shock balance sheets, potential exposure to COVID-19, and in the absence of government interventions. The results highlight that there are large and similar shares of the population across European countries that are likely to suffer from the economic fallout of containment measures – albeit through different channels.

We review 25 years of research on expatriate experiences concentrating on expatriate adjustment as a central construct, and relying on a general stressor-stress-strain framework. First, we consider who expatriates are, why their experiences differ from domestic employees, and what adjustment is. Conceptualizing (mal)adjustment in terms of stress, we next review the stressors and strains associated with it. Consolidating the wide range of antecedents (anticipatory and in-country) that have been studied to date, we note major patterns of effects and their implications for how HR managers can facilitate adjustment. Although relatively less research has focused on the consequences of adjustment, enough evidence exists to establish a bottom-line impact of poor adjustment on performance. To stimulate future efforts to understand the experiences of expatriates, we discuss the challenges and opportunities of continuing down this road of research.
