The 2012 Report “Transnational Insolvency: Global Principles for Co-operation in International Insolvency Cases” – commissioned by The American Law Institute in conjunction with The International Insolvency Institute – annexed 23 “Global Rules on Conflict-of-Laws Matters in International Insolvency Cases”. These proposed “Global Rules” are intended to “serve as legislative recommendations” to (inter alia) promote uniformity and greater certainty in the unpredictable area of conflict of laws. This article provides a brief commentary upon the 23 proposed Global Rules from an Australian perspective (comparing the effect and intent of each rule with the current Australian conflict-of-laws position) and offers some conclusions as to the merits of the “Global Rules” initiative.

The purpose of this article is to investigate the relationship between organizational and professional commitment of project workers. We first present (1) role-conflict theory and exchange theory to establish the multiple dimensions of commitment (affective, continuance, and normative) and (2) social identity theory to support our argument for different foci of commitment—organization and profession. Building on these theoretical lenses, we present the literature review that compares organizational and professional commitment of project workers with respect to the three dimensions of commitment. Adopting a positivist approach and a sample of 141 project workers, we use Pearson’s correlation to identify the relationship between affective organizational and affective professional, continuance organizational and continuance professional, and normative organizational and normative professional commitment. We report significant correlation between affective organizational commitment and affective professional commitment of project workers. The correlations between continuance organizational commitment and continuance professional commitment and normative organizational commitment and normative professional commitment are moderate. We then discuss the implications of these findings for the project management profession.

Organisational commitment is extensively represented in the human resource management and organisational behaviour literature as a key factor in the relationship between employees and their organisations. Although Allen and Meyer (1990) noted that an employee can experience the three components of organisational commitment simultaneously, in terms of commitment profiles, the majority of studies have looked at the antecedents and outcomes of affective, continuance, and normative commitment independently. There is still only limited research that has investigated the nature of commitment profiles and their implications for employee work-related behaviours (Gellatly Meyer and Luchak 2006; Herscovitch & Meyer 2002; Somers 2010; Wasti 2005). An area where the commitment profiles approach potentially provides new insights is on the nature of normative commitment.

What began as the “account manager’s conscience” has grown to be top-of-mind in Australian advertising today. Account planning is a hybrid discipline which uses research to bring the consumer voice to the campaign process during strategy generation, creative development and evaluation. In Australia, account planning is subjected to the “Vegemite Factor” where planners are spread too thinly across accounts and much of the market is dominated by freelance researchers and planners. This unique environment has shaped many different perceptions of account planning in Australia. These are compared with an international definition of account planning and the current research. While many basic tenants of the definition are shared by Australian advertising professionals, the difference appears to be in the ongoing nature, team approach and level of commitment. In Australia, account planners seem to be more facilitators of the strategic direction, than directors of it. Instead of exerting a sustained influence across the campaign, most energy appears to be expended at the start of campaign development, rather than extending through to its evaluation.

Dreaming of Amelia (2009) recounts a small group of HSC students’ final year of high school. Told from multiple perspectives, the novel focuses on shifting senses of self, maturity, and agency as the protagonists move from adolescence to adulthood. The central conflict of the novel results from two ‘bad kids from the bad crowd at bad Brookfield High’ (blurb) transferring to wealthy private school, Ashbury; Amelia and Riley are scholarship students who do not fit with Ashbury’s profile of 'normal student' as it is understood by the school’s students or staff, and their presence in the school community forces many people to reassess their understanding of individual value (or, at least, that’s what the novel claims happens). In the shifting of perceptions, allegiances, and relationships, each of the main characters achieves a stronger sense of their identity, and Dreaming of Amelia is thus firmly located within the tradition of Young Adult (YA) literature, with all its stereotypes of adolescence.

Cell based therapies require cells capable of self renewal and differentiation, and a prerequisite is the ability to prepare an effective dose of ex vivo expanded cells for autologous transplants. The in vivo identification of a source of physiologically relevant cell types suitable for cell therapies is therefore an integral part of tissue engineering. Bone marrow is the most easily accessible source of mesenchymal stem cells (MSCs), and harbours two distinct populations of adult stem cells; namely hematopoietic stem cells (HSCs) and bone mesenchymal stem cells (BMSCs). Unlike HSCs, there are yet no rigorous criteria for characterizing BMSCs. Changing understanding about the pluripotency of BMSCs in recent studies has expanded their potential application; however, the underlying molecular pathways which impart the features distinctive to BMSCs remain elusive. Furthermore, the sparse in vivo distribution of these cells imposes a clear limitation to their in vitro study. Also, when BMSCs are cultured in vitro there is a loss of the in vivo microenvironment which results in a progressive decline in proliferation potential and multipotentiality. This is further exacerbated with increased passage number, characterized by the onset of senescence related changes. Accordingly, establishing protocols for generating large numbers of BMSCs without affecting their differentiation potential is necessary. The principal aims of this thesis were to identify potential molecular factors for characterizing BMSCs from osteoarthritic patients, and also to attempt to establish culture protocols favourable for generating large number of BMSCs, while at the same time retaining their proliferation and differentiation potential. Previously published studies concerning clonal cells have demonstrated that BMSCs are heterogeneous populations of cells at various stages of growth. Some cells are higher in the hierarchy and represent the progenitors, while other cells occupy a lower position in the hierarchy and are therefore more committed to a particular lineage. This feature of BMSCs was made evident by the work of Mareddy et al., which involved generating clonal populations of BMSCs from bone marrow of osteoarthritic patients, by a single cell clonal culture method. Proliferation potential and differentiation capabilities were used to group cells into fast growing and slow growing clones. The study presented here is a continuation of the work of Mareddy et al. and employed immunological and array based techniques to identify the primary molecular factors involved in regulating phenotypic characteristics exhibited by contrasting clonal populations. The subtractive immunization (SI) was used to generate novel antibodies against favourably expressed proteins in the fast growing clonal cell population. The difference between the clonal populations at the transcriptional level was determined using a Stem Cell RT2 Profiler TM PCR Array which focuses on stem cell pathway gene expression. Monoclonal antibodies (mAb) generated by SI were able to effectively highlight differentially expressed antigenic determinants, as was evident by Western blot analysis and confocal microscopy. Co-immunoprecipitation, followed by mass spectroscopy analysis, identified a favourably expressed protein as the cytoskeletal protein vimentin. The stem cell gene array highlighted genes that were highly upregulated in the fast growing clonal cell population. Based on their functions these genes were grouped into growth factors, cell fate determination and maintenance of embryonic and neural stem cell renewal. Furthermore, on a closer analysis it was established that the cytoskeletal protein vimentin and nine out of ten genes identified by gene array were associated with chondrogenesis or cartilage repair, consistent with the potential role played by BMSCs in defect repair and maintaining tissue homeostasis, by modulating the gene expression pattern to compensate for degenerated cartilage in osteoarthritic tissues. The gene array also presented transcripts for embryonic lineage markers such as FOXA2 and Sox2, both of which were significantly over expressed in fast growing clonal populations. A recent groundbreaking study by Yamanaka et al imparted embryonic stem cell (ESCs) -like characteristic to somatic cells in a process termed nuclear reprogramming, by the ectopic expression of the genes Sox2, cMyc and Oct4. The expression of embryonic lineage markers in adult stem cells may be a mechanism by which the favourable behaviour of fast growing clonal cells is determined and suggests a possible active phenomenon of spontaneous reprogramming in fast growing clonal cells. The expression pattern of these critical molecular markers could be indicative of the competence of BMSCs. For this reason, the expression pattern of Sox2, Oct4 and cMyc, at various passages in heterogeneous BMSCs population and tissue derived cells (osteoblasts and chondrocytes), was investigated by a real-time PCR and immunoflourescence staining. A strong nuclear staining was observed for Sox2, Oct4 and cMyc, which gradually weakened accompanied with cytoplasmic translocation after several passage. The mRNA and protein expression of Sox2, Oct4 and cMyc peaked at the third passage for osteoblasts, chondrocytes and third passage for BMSCs, and declined with each subsequent passage, indicating towards a possible mechanism of spontaneous reprogramming. This study proposes that the progressive decline in proliferation potential and multipotentiality associated with increased passaging of BMSCs in vitro might be a consequence of loss of these propluripotency factors. We therefore hypothesise that the expression of these master genes is not an intrinsic cell function, but rather an outcome of interaction of the cells with their microenvironment; this was evident by the fact that when removed from their in vivo microenvironment, BMSCs undergo a rapid loss of stemness after only a few passages. One of the most interesting aspects of this study was the integration of factors in the culture conditions, which to some extent, mimicked the in vivo microenvironmental niche of the BMSCs. A number of studies have successfully established that the cellular niche is not an inert tissue component but is of prime importance. The total sum of stimuli from the microenvironment underpins the complex interplay of regulatory mechanisms which control multiple functions in stem cells most importantly stem cell renewal. Therefore, well characterised factors which affect BMSCs characteristics, such as fibronectin (FN) coating, and morphogens such as FGF2 and BMP4, were incorporated into the cell culture conditions. The experimental set up was designed to provide insight into the expression pattern of the stem cell related transcription factors Sox2, cMyc and Oct4, in BMSCs with respect to passaging and changes in culture conditions. Induction of these pluripotency markers in somatic cells by retroviral transfection has been shown to confer pluripotency and an ESCs like state. Our study demonstrated that all treatments could transiently induce the expression of Sox2, cMyc and Oct4, and favourably affect the proliferation potential of BMSCs. The combined effect of these treatments was able to induce and retain the endogenous nuclear expression of stem cell transcription factors in BMSCs over an extended number of in vitro passages. Our results therefore suggest that the transient induction and manipulation of endogenous expression of transcription factors critical for stemness can be achieved by modulating the culture conditions; the benefit of which is to circumvent the need for genetic manipulations. In summary, this study has explored the role of BMSCs in the diseased state of osteoarthritis, by employing transcriptional profiling along with SI. In particular this study pioneered the use of primary cells for generating novel antibodies by SI. We established that somatic cells and BMSCs have a basal level of expression of pluripotency markers. Furthermore, our study indicates that intrinsic signalling mechanisms of BMSCs are intimately linked with extrinsic cues from the microenvironment and that these signals appear to be critical for retaining the expression of genes to maintain cell stemness in long term in vitro culture. This project provides a basis for developing an “artificial niche” required for reversion of commitment and maintenance of BMSC in their uncommitted homeostatic state.

It is almost a truism that persons who occupy formal bureaucratic positions in schools may not actually be leaders if they were not role incumbents in a bureaucracy. It is also clear from studies of grassroots leaders that without the qualities of skills of leadership no one would follow them because they have no formal, hierarchical role upon which others were dependent to them. One of the reasons for re-examining the nature of grassroots leaders is to attempt to recapture those tactics or strategies which might be reconceptualized and utilized within more formal settings so that role dependent leadership becomes more effectual and trustworthy than one that is totally dependent on role authority. This reasoning is especially a critical need if there is a desire to work towards more democratic and collaborative working arrangements between leaders and followers, and where more flexible and dynamic relationships promise higher levels of commitment and productivity. Hecksher (1994) speaks of such a reconceptualization as part of a shift from an emphasis on power to one centered on influence. This paper examines the nature of leadership before it was subjected to positivistic science and later behavioural studies. This move follows the advice of Heilbrunn (1996) who trenchantly observed that for leadership studies to grow as a discipline, “it will have to cast a wider net” (p.11). Willis et. Al. (2008) make a similar point when they lament that social scientist have forced favoured understanding bureaucracies rather than grassroots community organizations, yet much can be gained by being aware of the tactics and strategies used by grassroots leaders who depend on influence as opposed to power. This paper, then, aims to do this by posing a tentative model of grassroots leadership and then considering how this model might inform and be used by those responsible for developing school leaders.

Professional service firms (PSFs) present HR professionals with a number of unique challenges, as they share characteristics of both service and knowledge intensive organizations. While many of these firms are relying on High Commitment Work Practices (HCWPs) to enhance critical employee behaviors such as service quality and turnover, the analysis presented in this paper raises questions about traditional understandings of commitment in professional service environments. In particular, data from three Danish financial investment PSFs suggest that employees are more committed to developing and promoting their own professions than to the organization itself, which has important implications for the way in which HCWPs are designed and utilized. In addition, the focus of HCWP research has favored the use of social exchange theory as an underpinning framework for considering the impact of HR practices on employee commitment. In the context of PSFs, we question the applicability of social exchange theory and instead draw upon the Ability-Motivation-Opportunity (AMO) framework (1982) to analyze how specific HRM practices contribute to the development of commitment, and to successful organizational outcomes in PSFs.

Recent decades have witnessed a global acceleration of legislative and private sector initiatives to deal with Cross-Border insolvency. Legislative institutions include the various national implementations of the Model Law on Cross-Border Insolvency (Model Law) published by the United Nations Commission on International Trade (UNCITRAL).3 Private mechanisms include Cross-Border protocols developed and utilised by insolvency professionals and their advisers (often with the imprimatur of the judiciary), on both general and ad hoc bases. The Asia Pacific region has not escaped the effect of those developments, and the economic turmoil of the past few years has provided an early test for some of the emerging initiatives in that region. This two-part article explores the operation of those institutions through the medium of three recent cases.

In this paper, we examine the lawfulness of a proposal to provide elective ventilation to incompetent patients who are potential organ donors. Under the current legal framework, this depends on whether the best interests test could be satisfied. It might be argued that, because the Mental Capacity Act 2005 (UK) (and the common law) makes it clear that the best interests test is not confined to the patient's clinical interests, but extends to include the individual's own values, wishes and beliefs, the proposal will be in the patient's best interests. We reject this claim. We argue that, as things currently stand, the proposal could not lawfully be justified as a blanket proposition by reference to the best interests test. Accordingly, a modification of the law would be necessary to render the proposal lawful. We conclude with a suggestion about how that could be achieved.

Mandatory child abuse and neglect reporting laws apply to teachers in many countries of the world. However, such laws have not yet been introduced for teachers in Malaysia, and there is debate about whether the laws should be extended to teachers at all. This paper aimed to investigate the level of support among teachers to assume mandatory reporting duties and to identify factors determining this support in Malaysia. A total of 668 teachers from 14 randomly selected public primary schools completed an anonymous self-administered questionnaire. Results showed that 44.4 per cent of the respondents supported legislation requiring teachers to report child abuse. Teachers of Indian ethnicity, those with a shorter duration of service in teaching (< 5 years), the availability of knowledgeable and supportive school staff and a higher level of commitment to reporting were significant factors affecting teachers' support for mandatory reporting. This study provides important insights into factors influencing teachers' support for the introduction of mandatory reporting legislation for teachers in Malaysia. Teachers do not unanimously support these laws and there is a lack of clarity about what such laws will mean for teachers. The data highlight the need for specific training programmes to raise teachers' awareness, build their confidence and enhance their willingness to report child abuse.

In this paper, we present initial results of an inductive, longitudinal case study of four firms that applied bricolage behaviors during resource constraints in firm emergence. Building on these cases, we discuss and extend existing research in bricolage theories by investigating how bricolage enables or hinders progress within firm creation. We explore the factors that places limits on the use of bricolage effectiveness during emergence. Specifically, in this paper, we discuss the impact of commitment and attention on bricolage effectiveness and how these influences may shape attempts to further progress and continue despite the resource constraints entrepreneurs often face in venture creation processes.

Maritime security has emerged as a critical legal and political issue in the contemporary world. Terrorism in the maritime domain is a major maritime security issue. Ten out of the 44 major terrorist groups of the world, as identified in the US Department of State’s Country Reports on Terrorism, have maritime terrorism capabilities. Prosecution of maritime terrorists is a politically and legally difficult issue, which may create conflicts of jurisdiction. Prosecution of alleged maritime terrorists is carried out by national courts. There is no international judicial institution for the prosecution of maritime terrorists. International law has therefore anticipated a vital role for national courts in this respect. The international legal framework for combating maritime terrorism has been elaborately examined in existing literature therefore this paper will only highlight the issues regarding the prosecution of maritime terrorists. This paper argues that despite having comprehensive intentional legal framework for the prosecution of maritime terrorists there is still some scopes for conflicts of jurisdiction particularly where two or more States are interested to prosecute the same offender. This existing legal problem has been further aggravated in the post September 11 era. Due to the political and security implications, States may show reluctance in ensuring the international law safeguards of alleged perpetrators in the arrest, detention and prosecution process. Nevertheless, international law has established a comprehensive system for the prosecution of maritime terrorists where national courts is the main forum of ensuring the international law safeguards of alleged perpetrators as well as ensuring the effective prosecution of maritime terrorists thereby playing an instrumental role in establishing a rule based system for combating maritime terrorism. Using two case studies, this paper shows that the role of national courts has become more important in the present era because there may be some situations where no State is interested to initiate proceedings in international forums for vindicating rights of an alleged offender even if there is a clear evidence of violation of international human rights law in the arrest, detention and prosecution process. This paper presents that despite some bottlenecks national courts are actively playing this critical role. Overall, this paper highlights the instrumental role of national courts in the international legal order.
