Aboriginal people across Australia suffer significant health inequalities compared with the non-Indigenous population. Evidence indicates that inroads can be made to reduce these inequalities by better understanding social and cultural determinants of health, applying holistic notions of health and developing less rigid definitions of wellbeing. The following article draws on qualitative research on Victorian Aboriginal peoples' relationship to their traditional land (known as Country) and its link to wellbeing, in an attempt to tackle this. Concepts of wellbeing, Country and nature have also been reviewed to gain an understanding of this relationship. An exploratory framework has been developed to understand this phenomenon focusing on positive (e.g., ancestry and partnerships) and negative (e.g., destruction of Country and racism) factors contributing to Aboriginal peoples' health. The outcome is an explanation of how Country is a fundamental component of Aboriginal Victorian peoples' wellbeing and the framework articulates the forces that impact positively and negatively on this duality. This review is critical to improving not only Aboriginal peoples' health but also the capacity of all humanity to deal with environmental issues like disconnection from nature and urbanisation.

Even though many schools and educational systems, from elementary to tertiary, state that they endorse antihomophobic policies, pedagogies, and programs, there appears to be an absence of education about, and affirmation of, bisexuality, and minimal specific attention to bi-phobia in curriculum, policy, and student welfare. Bisexuality continues to fall into the gap between the binary of heterosexuality and homosexuality across all educational sectors. These absences and erasures leave bisexual students, family members, and educators feeling silenced and invisibilized within school communities. Indeed, these absences and erasures have been considered a major factor in bisexual young people, family members, and educators in school communities experiencing worse mental, emotional, sexual, and social health than their homosexual or heterosexual counterparts. Also of interest is the persistence of bisexual erasure in adult-developed resources and programs, even though there is increasing evidence of sexual identities and practices in youth subcultures that are adopting shifting discursive and societal constructs of sexuality, characterized by notions of fluidity, ambisexuality, and a reluctance to label their sexuality according to the heterosexual/homosexual binary. The articles in this issue profoundly engage with and problematize the three impediments to education systems when those systems engage with sexual diversity instead of sexual duality, namely, erasure, exclusion by inclusion into gay and lesbian categories, and the absence of intersectionality (wherein other facets of identity and experience that interweave with sexuality are not taken into account, such as class, gender, Indigeneity/Aboriginality, ethnicity, geographical location, and religion).

The paper examines the effect of ownership structure and board characteristics on bank performance of GCC counties. Evidence indicates that the extent of the foreign ownership level has a significant positive association with the bank performance. However, concentrated ownership does appear to have a significant negative impact on performance and institutional ownership does not have any significant effect on performance. Other governance variables such as CEO duality and board size appear insignificant impact on performance. These results suggest a need to strengthen the internal control mechanisms within banks of GCC countries.

© 2015 Elsevier Ltd. Empirical examinations of the links between corporate governance and intellectual capital are underresearched, particularly from the context of emerging economies where corporate governance mechanisms tend to be largely ceremonial due to family dominance. This study aims to address this gap in the intellectual capital disclosure (ICD) literature by undertaking an empirical examination of the relationship between corporate governance and the extent of ICD of Bangladeshi companies. Inter alia, the key findings of this study suggest that there is a non-linear relationship between family ownership and the extent of ICD. This research also found that foreign ownership, board independence, and the presence of audit committees are positively associated with the extent of ICD. Conversely, family duality (i.e., where the positions of CEO and chairperson are occupied by two individuals from the same family) is negatively associated with the extent of ICD.

This paper investigates the association between Malaysian politically connected (PCON) firms and the cost of debt. We extend previous research that finds Malaysian PCON firms are perceived as being of higher risk by the market, and by audit firms, by providing evidence that lenders also perceive these firms as being of higher risk. We also find that PCON firms have a significantly (1) higher extent of leverage, (2) higher likelihood of reporting a loss, (3) higher likelihood of having negative equity, and (4) higher likelihood of being audited by a big audit firm. We suggest that PCON firms are charged higher interest rates by lenders as a result of efficient contracting given their higher inherent risks. Additionally, we find that CEO duality present in PCON firms is perceived by lenders as being more risky, and that a higher proportion of independent directors on the audit committee mitigate this perceived risk. © 2012.

This study examines the effect of directors’ human and social capital (i.e. board capital) on the level of corporate social responsibility (CSR) disclosures by drawing on insights from a resource-based view. It also investigates the effect of chief executive officer (CEO) power on this relationship. Data were obtained from annual reports of companies listed on the Dhaka Stock Exchange in Bangladesh from 2005 to 2013. We employ outside directors’ experiences and expertise as a proxy for board capital and measure CEO power using a ‘power index’ that comprises CEO duality, ownership, tenure and family CEO status. Results show that board capital is positively associated with CSR disclosure levels; however, CEO power is negatively associated with CSR disclosures and reduces the effect of board capital on CSR disclosures. Thus, we conclude that although board capital can improve CSR practices, CEO power can also inhibit these practices.

GroupIndia has emerged as a major source of migrants for developed countries including Australia; yet, there is a dearth of research on Indian migrant entrepreneurs, particularly women. Using qualitative methods of enquiry, we explore the perceptions of Indian migrant women entrepreneurs (MWEs) and their partners in Melbourne, Australia, about their entrepreneurship experiences from a family embeddedness perspective. More specifically, we explore how family embeddedness of Indian MWEs is influenced by certain factors which in turn influence their entrepreneurship experience. Our findings suggest that entrepreneurship among Indian MWEs is a complex phenomenon influenced by their being an Indian, a woman and a new Australian, all of which interact and influence their family dynamics and entrepreneurial experience. Our findings shed light on the duality of Indian culture which exerts both an enabling and a constraining influence on the family dynamics of MWEs, the constraining role of gender and the positive impact of their integration into the host country’s sociocultural context which all influence their family embeddedness and entrepreneurship. Contributing to the discussion on ‘ethnic’ and ‘women entrepreneurship’ from a family embeddedness perspective, we offer policy implications for facilitating entrepreneurship in the growing but under-researched cohort of Indian MWEs.

This study examines the linkages between board leadership structure in terms of CEO duality (CEOs who jointly serve as board chairs), the proportion of expert outside directors on the board (PENEDs) and voluntary corporate disclosures. Regression analyses of observations from 385 Hong Kong companies show that CEO duality is associated with lower levels of voluntary corporate disclosures. However, the negative CEO duality/voluntary disclosure association is weaker for firms with higher PENEDs suggesting that the expertise of non-executive directors (NEDs) moderates the CEO duality/corporate disclosures relationship.

In this paper, I explore the complex ethical dynamics of violence and nonviolence in Mahāyāna Buddhism by considering some of the historical precedents and scriptural prescriptions that inform modern and contemporary Buddhist acts of self-immolation. Through considering these scripturally sanctioned Mahāyāna ‘case studies,’ the paper traces the tension that exists in Buddhist thought between violence and nonviolence, outlines the interplay of key Mahāyāna ideas of transcendence and altruism, and comments on the mimetic status and influence of spiritually charged texts. It is the contention of this paper that violent scriptural metaphors can create paradigms of enactment that are paradoxically illustrative of the core ‘non-violent’ Mahāyāna virtues of compassion (karuṇā), giving (dāna), patience (kṣānti), and vigor (vīrya). The discussion will show that these virtues are underpinned by the Mahāyāna philosophical mainstays of non-duality (advayavāda), bodhisattvic transcendent altruism, skillful means (upāya), and dependent co-origination (pratītyasamutpāda).
