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.

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.

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.

The purpose of this paper is to determine how Australian workplaces, their managers and employees respond to those who are grieving at work, as a result of chronic or terminal illness, or caring for those with chronic or terminal illness. The review draws on Australian and relevant international literature and seeks to answer this question.

A literature review was undertaken in preparation for an Australian study examining workplace supports for people who are grieving – because they are carers, have experienced a death, or are balancing their own illness with their work. Using a range of search terms, the literature was searched for relevant work between 1980 and 2010. The search found examples of workplace supports throughout the world and some developing Australian literature.

Despite illness and death occurring at any stage of a person's life, there is little research that identifies workplace issues associated with grief and loss. And while workplace legislation allows for minimal supports, there was evidence that some workplaces have begun to offer flexibility for work life balance.

Effective workplace supports will involve individual and workplace responses, but also require legislative approaches in order to effect broad‐based system change.

The paper compares Australian and international literature about workplace supports and provides an overview of the issues arising.

This study sought to identify teachers' overall experiences in teaching social studies, the considerations they make in planning and implementing social studies lessons in the absence of mandated curriculum, approaches to social studies instruction and the role of legislation on social studies instruction.

Two practicing teachers at different grade levels participated in this study to allow for comparative case study analysis. Teachers were observed teaching social studies lessons and then were interviewed to gain an understanding of their perspectives on teaching social studies at the elementary level and the role that administrative and legislative messaging played in their decision-making.

The lack of a scripted and formal program for social studies created opportunities for teacher autonomy and content integration in lessons. This is especially true for teachers that place a high value on social studies content and skills. Persistent issues, such as limited time and mandated testing pressures, continue to create barriers that teachers must work to overcome.

Since teachers play a critical role in the enactment of policy and curriculum, when a formal curriculum program is absent, opportunities arise. Control of the classroom and inherent messaging therein continues to create a high value battleground. When teachers are given the autonomy to set lesson outcomes, opportunities for quality instruction, such as project based learning and content integration, are possible.

Police services, police associations and police foundations now engage in philanthropy and these efforts are communicated using social media. This paper examines social media framing of the philanthropic and charitable work of police in Canada.

Drawing from discourse and semiotic analyses, the authors examined the ways that police communications frame contributions to charity and community’s well-being. Tweets were analyzed for themes, hashtags and images that conveyed the philanthropic work of police services, police associations as well as police foundations.

The authors discovered four main forms of framing in these social media communications, focusing on community, diversity, youth and crime prevention. The authors argue that police used these communications as mechanisms to flaunt social capital and to boost perceptions of legitimacy and benevolence.

More analyses are needed to examine such representations over time and in multiple jurisdictions.

Examining police communications about philanthropy not only reveals insights about the politics of giving but also the political use of social media by police.

Social media is used by organizations to position themselves in social networks. The increased use of social media by police, for promoting philanthropic work, is political in the sense that it aims to bolster a sense of legitimacy.

A distinction must be drawn between a dismissal on the one hand, and on the other a repudiation of a contract of employment as a result of a breach of a fundamental term of that contract. When such a repudiation has been accepted by the innocent party then a termination of employment takes place. Such termination does not constitute dismissal (see London v. James Laidlaw & Sons Ltd (1974) IRLR 136 and Gannon v. J. C. Firth (1976) IRLR 415 EAT).
