To simulate the kinematics associated with mining‐induced subsidence in a blocky rock mass, a hybrid rigid block model was developed by combining a small displacement code with a large displacement code. Gravity was applied to a rigid block mesh using an implicit formulation and the equilibrium displacements are then used as initial conditions for an explicit analysis in which excavation of a longwall mine panel and subsequent subsidence was simulated. A parameter study was performed to evaluate the influence of rigid block contact stiffness, vertical joint density, and contact roughness on mining‐induced strata movements for comparison with previously obtained field measurements. The best agreement between measured and calculated displacements was obtained when a relatively low stiffness value was maintained constant for all contacts. A surprising result was that neither increasing the density of vertical joints nor reducing the rigid block contact roughness improved the agreement between measured and simulated displacements.

From one angle, abortion law appears to confirm the regime politics account of the Supreme Court; after all, the Reagan/Bush coalition succeeded in significantly curtailing the constitutional protection of abortion rights. From another angle, however, it is puzzling that the Reagan/Bush Court repeatedly refused to overturn Roe v. Wade. We argue that time and again electoral considerations led Republican elites to back away from a forceful assertion of their agenda for constitutional change. As a result, the justices generally acted within the range of possibilities acceptable to the governing regime but still typically had multiple doctrinal options from which to choose.

This study aimed to identify subgroups of esports players based on their gaming behavior patterns across game genres and compare self-efficacy, social efficacy, loneliness and three dimensions of quality of life between these subgroups.

324 participants were recruited from prolific academic to complete an online survey. We employed latent profile analysis (LPA) to identify subgroups of esports players based on their behavioral patterns across genres. Additionally, a one-way multivariate analysis of covariance (MANCOVA) was conducted to test the association between cluster memberships and development and well-being outcomes, controlling for age and gender as covariates.

LPA analysis identified five clusters (two single-genre gamer groups, two multigenre gamer groups and one all-genre gamer group). Univariate analyses indicated the significant effect of the clusters on social efficacy, psychological health and social health. Pairwise comparisons highlighted the salience of the physical enactment-plus-sport simulation genre group in these outcomes.

This study contributes to the understanding of the development and well-being benefits experienced by various esports consumers, as well as the role of specific gameplay in facilitating targeted outcomes among these consumer groups.

The basis of this study is Kelley’s (1992) two-dimensional model, which measures five follower types. Previous investigations did not support the validity of Kelley’s model. Although the model is utilized in research, the validity and reliability of the Kelley Followership Questionnaire (KFQ) is still in question. In this study, the KFQ validity was tested after revision of the instrument. Factor analysis revealed a three-factor model disputing the theorized two-factor model. Factors of the KFQ-R convergent validity were supported by significant correlations with critical thinking disposition and work engagement scales. This research project is intended to promote the study of the followership construct.

Organizations are changing their new product development processes in order to introduce improvements to innovation performance. The purpose of this study is two‐fold. First, we wish to characterize the change process to examine whether the approach taken represents reengineering, or continuous quality improvement. Second, we wish to compare the process of change to an ideal model of change, and see how closely practice followed theory. Case studies of six companies are developed from interviews of executives, reengineering team members, and other organizational members. The actual change process tended to consist of components of both reengineering and continuous quality improvement, and there were some significant gaps between practice and theory.

Through a survey of 200 employees working in five of the thirty establishments analysed in previous research about the microeconomic effects of reducing the working time (Cahier 25), the consequences on employees of such a reduction can be assessed; and relevant attitudes and aspirations better known.

This study tests the signaling and tunneling models of dividend policies by examining the relationship between the ownership structure and the dividend payout in a setting where strong institutional governance and weak firm-level governance coexist.

Chinese American Depository Receipts (ADRs) listed in the US offer an excellent opportunity to study dividend policy where strong institutional governance and weak firm-level governance coexist. Using a sample of 161 Chinese ADRs from 2004 to 2018, this study examines the relationship between the firm's ownership structure and cash dividend policy.

This study shows that high levels of controlling shareholder ownership and high levels of state ownership are associated with high dividend payouts. A high level of controlling shareholder ownership has a negative effect on its firm value. Dividend payments in those firms mitigate the negative effect, consistent with the signaling (substitution) model. A high level of state ownership is beneficial to its firm value. However, high dividend payment in those firms decreases the benefit, supporting the tunneling model.

This study covers 161 Chinese ADRs listed in the US with a total market capitalization of over $2 trillion and reveals that dividend tunneling could occur in Chinese government controlled ADRs. Findings in this study would offer valuable insights for US investors and regulators.

This paper extends the tunneling hypothesis to the topic of dividend policy in a setting where strong institutional governance and weak firm-level governance coexist. This study shows that tunneling through dividends can happen among Chinese government controlled ADRs in the US. It also complements the literature by extending the examination of the dividend tunneling model from a relatively small universe of master limited partnership (Atanssov and Mandell, 2018) to a larger universe of Chinese ADRs listed in the US with a total market capitalization over $2 trillion US dollars.

In this paper, we propose a new conceptualization of the purpose of the corporation in relation to its activities. This conceptualization builds upon the existing distinction between the corporation as a legal vehicle and the enterprise as an economic organization, but renews the approach of the enterprise. We argue that the enterprise is a peculiar historical form of economic organization that emerged in the late nineteenth century to not only produce but also create new goods and technologies. This creative purpose involved a new type of managerial authority, not grounded in corporate law, but institutionalized in other branches of law, such as labor law. The legitimacy of the managers relied on the premise that the enterprise’s creative power would be harnessed for collective progress. However, this new view of the enterprise was insufficiently conceptualized in the twentieth century and continued to be governed by standard corporate law. This allowed managers to be seen as agents of shareholders, and the purpose of collective progress to be replaced by the interests of shareholders. Our analysis has important implications for the purpose of the corporation. As enterprises become more innovative and impactful, we argue that they can no longer be governed by traditional corporate law. If the corporation remains the legal cloth for business activities, then its purpose must consider the nature and impacts of these activities. We therefore interpret the new legal forms of purpose-driven corporation as an appropriate framework to restore the enterprise and a collective purpose within corporate law.

This chapter argues we should not regard school-to-school collaboration as simply a mechanism for outcome-driven improvement but rather consider the establishment of teacher relationships as the necessary priority when building highly effective collaborative networks. By revisiting the research of Sandra Kruse, Amanda Datnow and Andy Hargreaves, we develop an additional tool to Hood’s matrix of regulation and cohesion in an effort to position collaborative networks in the context of international private fee-paying schools. The tool visualizes the collaborative network development as a relationship continuum in which time is the necessary driver of a network’s success. The 12 Asian private international schools in the case study were given collaborative framework guidance drawn from multiple sources. Subsequently, the enablers and hindrances reported by the collaboration leads highlight the need for trust and teacher agency development to be prioritized by leadership. Finally, on sharing some lessons learned from the case study, we close by arguing the value of collaboration lies in opening the door to allow for agenetic cultures that build reflexive practitioners.
