The value of circles and the dangers of straight lines

This article focuses on how respectful learning relationships based on reciprocity between a Anglo-western raised educator and South Sudanese Australian students and graduates in social work and welfare courses in a regional location have (re)shaped the development of a research process. A reflective critique is intertwined with a description of my search (as an experienced practitioner but new researcher) for an appropriate ethical cross cultural framework for researching and advocating with a small ethnic population in a regional location. This includes a description of the process of exploring the need for, and positioning of, changing and re-creating relationships between the ‘researcher(s)’ and the ‘researched’ as co-authors; co-researchers; collaborators and participants to address issues of selfdetermination and power in the context of cross cultural research, education and human rights. The motivation to research seems a pivotal part of ethics in cross cultural research. As an educator I became concerned that the courses I taught in, and my own teaching practices, were (unintentionally) discriminatory. There appeared to be a lack of acknowledgement and/or action regarding the ingrained Western whiteness permeated and privileged knowledge and approaches in the construction and delivery of courses. I did not think I was adequately responding to, recognising or incorporating the different knowledge’s, strengths and needs of South Sudanese Australian students and graduates. There was a lack of fit between the academic rhetoric of human rights and diversity and my/our educator practice. This article explores the ‘corralling’ effect of mainstream research culture with attention to its potential for seduction and corruption that tends to separate the passion from the researcher, the researcher from the researched, and the actual issue(s) of concern ….from everyone.

Design and analysis of efficient rectifiers for wireless power harvesting in DBS devices

This paper presents an analysis of optimum rectifier circuits for wireless energy harvesting in deep brain stimulation (DBS) devices. Since DBS demands compact and low power consumption devices, small, high conversion efficient, and high output voltage rectifiers need to be developed. The investigation that is presented in this paper is analytical and simulated based. Analysis on a variety of circuit configurations brings more evidence to improve the performance of rectifiers. Analytical parameters influencing the output DC voltage and the efficiency of the rectifiers are described. The operating frequency of the 915 MHz industrial, scientific and medical (ISM) radio band is used in this study. The maximum conversion efficiency of the LC matched half wave rectifier, the Greinacher voltage doubler, the Delon doubler, and the 2-stage voltage multiplier is obtained as 56.34%, 74.45%, 71.48%, and 31.44%, respectively, at the 30 dBm input power level. The corresponding maximum output DC voltages are 6.27 V, 16.83 V, 13.36 V, and 9.20 V. Thus the Greinacher voltage doubler is deemed as the best configuration according to the conversion efficiency and the output voltage measurements.

The game-changers: exploring radically transformational challenges confronting education business leadership

This paper highlights the radical and rapid changes occurring at all levels of education that are having a profound impact on educational leadership, governance, business and administration. These far-reaching transformations include: competition from a rapidly expanding unregulated private sector; the international impact of de-regulation; the demise of union power, secure education jobs, time-honored hours and working conditions; constant, rapid education policy change and the proliferation of open access technologies which are rendering physical education campuses less relevant or obsolete. The paper suggests that at this stage in history we are witnessing game-changing forces that are fundamentally altering educational provision, the nature of education work, the education workforce, educational outcomes, educational leadership, governance and business. Most importantly, it argues that educational leaders and education business managers need to be ready for them and more instrumental in policy debates arising in their wake. The paper concludes with ideas for responsive action from education business leaders.

The impact of divergent historical and cultural factors on convergence in global communication practice

Communication practice is increasingly converging around globally consistent approaches and techniques shaped by both globalisation and globalising communications technologies. However, this paper argues, national and regional practice histories and cultural characteristics have shaped, and continue to shape, practice in individual markets. The paper analyses the extent of that these divergent histories and cultures have shaped the structure and practices of the public relations industry in Australia and other countries. The paper challenges the common assumptions about public relations development and industry practice having developed from a predominantly US-based model progressively disseminated globally. It traces the history of public relations in Australia, counterpointing its distinctive origins, to the US-origin thesis. It also examines the impact of demography and diverse national culture on industry shape and practice, comparing the Australian industry to that of other industries around the world. It uses mini-case studies of campaigns in specific countries to assess the extent to which they are culturally bound by historical and cultural differences and the extent to which they are capable of being transferred or adapted to individual markets. For instance, assumptions about globally consistent brand identities are contradicted by McDonald’s’ branding practices in markets such as Canada and Japan. The paper also discusses how emerging market PR industries are being shaped by distinctive and divergent cultures and development paths and may create new structural and practice models as the emerging economies becoming dominant internationally. The authors suggest that history and cultural diversity continue, and will continue to, shape national and regional practices.

The delivery of teacher education programmes in regional Victoria, Australia: Opportunities and challenges

A significant number of Australian universities have multiple campuses (Winchester and Sterk 2006). To manage successful student learning outcomes, Winchester and Sterk (2006) argue that universities may experience challenging teaching and learning issues such as fragmentation, duplication, inconsistency and lack of equitable opportunities for students across the various sites. In recent years, online educational technology has enabled Australian universities to rethink the ways in which they deliver programmes (Smith, Ling and Hill 2006). Such a paradigm and technological shift provide a ‘window of opportunity’ to meet the challenging demands of serving multiple campuses (Bottomley 2000), especially those in regional areas. In Victoria, at June 2012, the regional population was 1.38 million (Australian Bureau of Statistics 2013). However, Polesel’s (2009) report found that students from regional areas defer university at twice the rate of metropolitan students. There is also evidence that students in regional areas, on the one hand, consider such areas as a learning environment with many advantages (e.g. small classes and a compact campus)(Ellis et al. 2005). On the other hand, students’ different interests can often be overlooked in educational settings (Semke and Sheridan 2012).
This paper will report on the results of a baseline study using survey methodology, which examined the challenges and opportunities of delivering elements of two undergraduate programmes in regional areas in Victoria, Australia. In particular, the research focused on two selected undergraduate teacher education programmes: (1) primary education; and (2) early childhood education. Focused discussion data, gathered from academics involved in delivering the programmes in the regional campuses will be presented as an analysis of issues and practices of teaching and learning in the 21st century. Implications for the provision of a quality learning experience and environment for students and for the course marketing strategies will be discussed.

Nutritional psychiatry research: an emerging discipline and its intersection with global urbanization, environmental challenges and the evolutionary mismatch

In 21st-century public health, rapid urbanization and mental health disorders are a growing global concern. The relationship between diet, brain function and the risk of mental disorders has been the subject of intense research in recent years. In this review, we examine some of the potential socioeconomic and environmental challenges detracting from the traditional dietary patterns that might otherwise support positive mental health. In the context of urban expansion, climate change, cultural and technological changes and the global industrialization and ultraprocessing of food, findings related to nutrition and mental health are connected to some of the most pressing issues of our time. The research is also of relevance to matters of biophysiological anthropology. We explore some aspects of a potential evolutionary mismatch between our ancestral past (Paleolithic, Neolithic) and the contemporary nutritional environment. Changes related to dietary acid load, advanced glycation end products and microbiota (via dietary choices and cooking practices) may be of relevance to depression, anxiety and other mental disorders. In particular, the results of emerging studies demonstrate the importance of prenatal and early childhood dietary practices within the developmental origins of health and disease concept. There is still much work to be done before these population studies and their mirrored advances in bench research can provide translation to clinical medicine and public health policy. However, the clear message is that in the midst of a looming global epidemic, we ignore nutrition at our peril.

Framing and enhancing distributed leadership in the quality management of online learning environments in higher education

This article reports on the findings of senior leadership interviews in a nationally funded project on distributed leadership in the quality management of online learning environments (OLEs) in higher education. Questions were framed around the development of an OLE quality management framework and the situation of the characteristics of distributed leadership at the core of the framework. The project’s premise is that distributed leadership is a descriptive reality of managing OLEs given the various leadership parties involved and the complexities of the contemporary technological landscape. Leaders’ understandings of distributed leadership were examined—its nature, value and potential for advancing the quality management of OLEs. There was confirmatory evidence of its reality, but its meaning and value were not uncritically accepted. It can be concluded that building distributed leadership must start through deliberative formal leadership commitment and action starting at the highest levels of the institution.

Sociocultural influences on strategies to lose weight, gain weight, and increase muscles among ten cultural groups

This study determined how sociocultural messages to change one's body are perceived by adolescents from different cultural groups. In total, 4904 adolescents, including Australian, Chilean, Chinese, Indo-Fijian, Indigenous Fijian, Greek, Malaysian, Chinese Malaysian, Tongans in New Zealand, and Tongans in Tonga, were surveyed about messages from family, peers, and the media to lose weight, gain weight, and increase muscles. Groups were best differentiated by family pressure to gain weight. Girls were more likely to receive the messages from multiple sociocultural sources whereas boys were more likely to receive the messages from the family. Some participants in a cultural group indicated higher, and others lower, levels of these sociocultural messages. These findings highlight the differences in sociocultural messages across cultural groups, but also that adolescents receive contrasting messages within a cultural group. These results demonstrate the difficulty in representing a particular message as being characteristic of each cultural group.

Mega-events and mega-profits: Unravelling the Vancouver 2010 security–development nexus

Academic and political commentators have commonly sought to understand the Olympics as a cultural dynamic, a "spectacle" that motivates certain actors to project their relative interests in localized spaces and as well on a global scale (Hiller 2006; Boyle and Haggerty 2009b ). Mega-events, as this argument goes, are monumental cultural events (Roche 2000) that rely on the audacity of spectacle to dramatize and condition the cultural, political, legal and economic landscape. Extending these insights into surveillance studies, Boyle and Haggerty (2009b: 259-260) position spectacle and the disciplinary mechanisms of anxieties associated with mega-events to explain the risk management practices of security planners. The dynamic social implications of the spectacle condition dramatic regimes of securitization and surveillance such that sovereign power emanates from the production and consumption of spectacle. In similar fashion Vida Bajc (2007: 1648) writes that security meta-rituals "demonstrate[s] that the process of transformation of [the] public space [of mega-events] from one of routine of daily life into a sterile area [that] has a ritual form [that] .... separates insiders from outsiders and brings about a new socio-political reality." Put another way, the "security-meta ritual" legitimates security and surveillance practices by normalizing the social hierarchies it imposes. Bajc focuses on the over-determination of dividing practices in mega-event security, but the signifying practices associated with capital are absent (perhaps due to her empirical focus on presidential addresses). Klauser (2008: 181) links commercialization and mechanisms of surveillance, but only by foregrounding the significance of "neutralized space" created by granting absolute commercial rights to event sponsors. Neoliberalprivatization and its articulation with security and surveillance, however, cannot be reduced to control over sponsorship rights and consumptive practices in particular urban "zones," nor can it be limited by the methodological temporality of the event itself.

Adherence to therapeutic guidelines for patients with community-acquired pneumonia in Australian hospitals

Community-acquired pneumonia (CAP) is a significant cause of morbidity and mortality, particularly in elderly patients, and is associated with a considerable economic burden on the healthcare system. The combination of high incidence and substantial financial costs necessitate accurate diagnosis and appropriate management of patients admitted with CAP. This article will discuss the rates of adherence to clinical guidelines, the use of severity scoring tools and the appropriateness of antimicrobial prescribing for patients diagnosed with CAP. The authors maintain that awareness of national and hospital guidelines is imperative to complement the physicians' clinical judgment with evidence-based recommendations. Increased use of pneumonia severity assessment tools and greater adherence to therapeutic guidelines will enhance concordant antimicrobial prescribing for patients with CAP. A robust and multifaceted educational intervention, in combination with antimicrobial stewardship programs, may enhance compliance of CAP guidelines in clinical practice in Australia.

Power, effects, confidence, and significance: an investigation of statistical practices in nursing research

Objectives: To (a) assess the statistical power of nursing research to detect small, medium, and large effect sizes; (b) estimate the experiment-wise Type I error rate in these studies; and (c) assess the extent to which (i) a priori power analyses, (ii) effect sizes (and interpretations thereof), and (iii) confidence intervals were reported. Design: Statistical review. Data sources: Papers published in the 2011 volumes of the 10 highest ranked nursing journals, based on their 5-year impact factors. Review methods: Papers were assessed for statistical power, control of experiment-wise Type I error, reporting of a priori power analyses, reporting and interpretation of effect sizes, and reporting of confidence intervals. The analyses were based on 333 papers, from which 10,337 inferential statistics were identified. Results: The median power to detect small, medium, and large effect sizes was .40 (interquartile range [. IQR]. = .24-.71), .98 (IQR= .85-1.00), and 1.00 (IQR= 1.00-1.00), respectively. The median experiment-wise Type I error rate was .54 (IQR= .26-.80). A priori power analyses were reported in 28% of papers. Effect sizes were routinely reported for Spearman's rank correlations (100% of papers in which this test was used), Poisson regressions (100%), odds ratios (100%), Kendall's tau correlations (100%), Pearson's correlations (99%), logistic regressions (98%), structural equation modelling/confirmatory factor analyses/path analyses (97%), and linear regressions (83%), but were reported less often for two-proportion z tests (50%), analyses of variance/analyses of covariance/multivariate analyses of variance (18%), t tests (8%), Wilcoxon's tests (8%), Chi-squared tests (8%), and Fisher's exact tests (7%), and not reported for sign tests, Friedman's tests, McNemar's tests, multi-level models, and Kruskal-Wallis tests. Effect sizes were infrequently interpreted. Confidence intervals were reported in 28% of papers. Conclusion: The use, reporting, and interpretation of inferential statistics in nursing research need substantial improvement. Most importantly, researchers should abandon the misleading practice of interpreting the results from inferential tests based solely on whether they are statistically significant (or not) and, instead, focus on reporting and interpreting effect sizes, confidence intervals, and significance levels. Nursing researchers also need to conduct and report a priori power analyses, and to address the issue of Type I experiment-wise error inflation in their studies. © 2013 .

Heritage conservation futures in an age of shifting global power

This article argues that international conservation and heritage governance are now entering new and historically important phases. The economic and political shifts that characterize globalization today are providing a platform for non-Western modes of heritage governance to gain newfound legitimacy on the international stage. With the appropriation of cultural heritage for commercial and political purposes occurring at all levels within the emerging economies of Asia, South America, the Middle East, and Africa, heritage conservation aid now plays an important role in the cultural diplomacy and soft power strategies of numerous countries in these regions. Analyses of the globalization of heritage governance in the mid–late 20th century have focused primarily on intergovernmental bodies, such as UNESCO, at the expense of critically reading the role nation-states continue to play in international conservation and heritage governance policy. Using examples from Asia, this paper addresses this imbalance by re-centering the nation-state in an account that argues the rise of heritage diplomacy, coupled with today’s shifting global order and ongoing reduction in UNESCO’s capacity, hold important implications for heritage conservation over the coming decades.
