Abstract
Although different facets of managerial third‐party intervention in organizations have been explored, we know little about how managers should intervene in different disputes for resolving them successfully. In this study, a prescriptive model of intervention strategy selection proposed by Elangovan (1995) is tested. Data on successful and unsuccessful interventions were collected from senior managers in different organizations. The results show that following the prescriptions of the model leads to a significant increase in the likelihood that an intervention would be successful as well as in the degree of success of the intervention, thereby supporting a contingency view of dispute intervention.

Abstract
Identification in a regression discontinuity (RD) design hinges on the discontinuity in the probability of treatment when a covariate (assignment variable) exceeds a known threshold. If the assignment variable is measured with error, however, the discontinuity in the relationship between the probability of treatment and the observed mismeasured assignment variable may disappear. Therefore, the presence of measurement error in the assignment variable poses a challenge to treatment effect identification. This chapter provides sufficient conditions to identify the RD treatment effect using the mismeasured assignment variable, the treatment status and the outcome variable. We prove identification separately for discrete and continuous assignment variables and study the properties of various estimation procedures. We illustrate the proposed methods in an empirical application, where we estimate Medicaid takeup and its crowdout effect on private health insurance coverage.

Abstract
In a service-led, knowledge-based economy, employers increasingly expect universities to deliver a workforce suited to this environment. This emphasis is evident in contemporary Australian higher education, which is shifting to an acquisition of vocational outcomes. However, vocational outcomes are not traditionally viewed as outcomes of liberal arts programs. Balancing new expectations with traditional perspectives generates a tension between assuring graduates employment outcomes and maintaining the integrity of the Bachelor of Arts (BA) as a liberal arts program. Getting it wrong can result in fragmented and unstable curricula. One of the many ways that Australian BA programs are grappling with this problem is through the provision of work-integrated learning (WIL) opportunities for liberal arts students. In professions-based programs such as engineering or dentistry, the shape and nature of these courses may be obvious. It is less so in the generalist BA. Australian BA programs offer students the opportunity to engage with WIL in a variety of ways. Evidence from national studies investigating the Australian BA between 2008 and 2016 highlight common features of practice – such as the objectives, activities, and structure, and indicate that two approaches to providing WIL opportunities in the BA are evident. In order to meet the goals and aspirations of both economic and social purposes of higher education, liberal arts programs tend to adopt either a transactional or a transformational model. Each model has particular characteristics and approaches to practice that can inform the development of new programs and policies more globally.

Abstract
Much of the extant management research implies that the existence of industries and organizations depends on variables and factors largely beyond their control, and survival is the result of a happy confluence of their origins, events, and growth rather than actions of conscious volition. The authors suggest that industry circumstances can be overcome. So, rather than studying rates of organization population change as effects of environmental change, the authors propose that some managerial actions can be taken that, in the aggregate, will affect the industry context. Changes in concentration should influence the environment in which industry members will compete later. Migration moves and rationalization of production facilities, along with organization population pressures, should exert strong influences on changes in the industry environments. Such findings suggest that some degree of strategic choice is at work and that firms have some discretionary choice in their industries.

Abstract
This chapter explores ways that tablet devices can be used to support the inclusion of students with disability in inclusive classrooms. A short description of the evidence of efficacy of using tablets to support students with disability is provided. Ways to use tablet devices to support students with disability in the areas of communication, academics, organisation and social emotional skills to support their inclusion in mainstream classrooms are addressed. Lastly, barriers to using tablets to support students with disability in inclusive classrooms are described and ways to remove these barriers are suggested.

Abstract
The sexual and erotic dimensions inherent in leadership’s physicality impact on power dynamics within organizations but have been rendered largely invisible by current scholarship. In organizational practice, leadership is a masculine activity ideally carried out by male bodies, such that women’s leadership is still perceived as problematic. This suggests that the field is fearful of allowing sexual bodies to pollute what should be a functional, cognitive and instrumental activity. This chapter therefore draws on Julia Kristeva’s concept of abjection to explain how and why the sexual body is positioned as the unspoken other of leadership. To do this, I explore the representation of two very contrasting leaders, Jean Luc Picard and the Borg Queen, in the popular film Star Trek: First Contact. The film illuminates how leadership ideally resides in a virile, mastered and distant male body. The sexual female body is represented as disgusting, dangerous, and a source of contamination and so must be cast out and destroyed. Finally, I ask whether the representation of the Borg Queen is useful as a transgressive means to undermine the abjection of the female leader’s body. However, I conclude that to counter abjection, scholars of leadership need instead to build discursive and material practices that revalue the feminine and respect the alterity of self and others.

Abstract
The BEKK GARCH class of models presents a popular set of tools for applied analysis of dynamic conditional covariances. Within this class the analyst faces a range of model choices that trade off flexibility with parameter parsimony. In the most flexible unrestricted BEKK the parameter dimensionality increases quickly with the number of variables. Covariance targeting decreases model dimensionality but induces a set of nonlinear constraints on the underlying parameter space that are difficult to implement. Recently, the rotated BEKK (RBEKK) has been proposed whereby a targeted BEKK model is applied after the spectral decomposition of the conditional covariance matrix. An easily estimable RBEKK implies a full albeit constrained BEKK for the unrotated returns. However, the degree of the implied restrictiveness is currently unknown. In this paper, we suggest a Bayesian approach to estimation of the BEKK model with targeting based on Constrained Hamiltonian Monte Carlo (CHMC). We take advantage of suitable parallelization of the problem within CHMC utilizing the newly available computing power of multi-core CPUs and Graphical Processing Units (GPUs) that enables us to deal effectively with the inherent nonlinear constraints posed by covariance targeting in relatively high dimensions. Using parallel CHMC we perform a model comparison in terms of predictive ability of the targeted BEKK with the RBEKK in the context of an application concerning a multivariate dynamic volatility analysis of a Dow Jones Industrial returns portfolio. Although the RBEKK does improve over a diagonal BEKK restriction, it is clearly dominated by the full targeted BEKK model.
