A qualitative study exploring barriers to a model of shared care for pre-school children`s oral health

Objective To explore the oral health beliefs and practices of primary health care professionals which may act as barriers to the development of a model of shared care for the oral health of pre-school children.

Design Qualitative focus group discussions and semi-structured interviews.

Setting Four rural local government areas in Victoria, Australia, 2003.

Subjects and methods Subjects: maternal and child health nurses, general medical practitioners, dental professionals and paediatricians working in the four local government areas. Data collection: discipline specific focus groups and semi-structured interviews. Data analysis: transcription, coding, clustering and thematic analysis.

Results Several strong themes emerged from the data. All participants agreed that dental caries is a significant health issue for young children and their families. Beliefs about the aetiology of dental caries and its prevention were variable and often simplistic, focusing predominantly on diet. Dental professionals did not believe that they had a primary role in the oral health of pre-school aged children but that others particularly maternal and child health nurses did. However other health care professionals were not confident in assuming this role.

Conclusions This study has identified important barriers and possible strategies for the development of an integrated and shared approach to preventing dental caries in pre-school aged children. Clear and consistent oral health information and agreed roles and responsibilities need to be developed.

Out of pocket costs to stroke patients during the first year after stroke - results from the North East Melbourne stroke incidence study

Non-reimbursed ‘out of pocket’ costs to stroke patients have not been included in existing cost of illness studies. We aimed to determine the nature and magnitude of ‘out of pocket’ costs to stroke patients during the first year after stroke. ‘Out of pocket’ costs during the first year after stroke were documented for 165 persons registered in a community-based stroke incidence study during 1996/1997. Virtually all cases reported some ‘out of pocket’ costs. The average cost over 12 months was A$1110. The highest cost items were home modifications, aids and equipment. The most commonly incurred expense was for prescription medications. Total ‘out of pocket’ costs incurred by first-ever stroke patients in Australia in 1997 were estimated to be A$29 million or 5% of the total cost of stroke. The majority of ‘out of pocket’ costs relate to post-acute care aimed at minimising disability and handicap rather than to ‘acute’ healthcare.

A mechanistic study of the intestinal absorption of crypotanshinone, the major active constituent of Saliva miltiorrhiza

The nature of intestinal absorption of most herbal medicine is unknown. Cryptotanshinone (CTS) is the principal active constituent of the widely used cardiovascular herb Salvia miltiorrhiza (Danshen). We investigated the oral bioavailability of CTS in rats and the mechanism for its intestinal absorption using several in vitro and in vivo models:1) Caco-2 cell monolayers; 2) monolayers of MDCKII cells overexpressing P-glycoprotein
(PgP); and 3) single-pass rat intestinal perfusion with mesenteric vein cannulation. The systemic bioavailabilities of CTS after oral and intraperitoneal administration at 100 mg/kg were 2.05 and 10.60%, respectively. In the perfused rat intestinal model, permeability coefficients based on CTS disappearance from the luminal perfusate (P_lumen) were 6.7- to 10.3-fold higher than permeability coefficients based on drug appearance in venous blood (P_blood). P_blood significantly increased in the presence of the P-gP inhibitor, verapamil. CTS transport across Caco-2 monolayers was pH-, temperature- and ATP-dependent. The transport from the apical (AP) to the basolateral (BL) side was 3- to 9-fold lower than that from the BL to the AP side. Inclusion of verapamil (50 µM) in both AP and BL sides abolished the polarized CTS transport across Caco-2 cells. Moreover, CTS was significantly more permeable in the BL to AP than in the AP to BL direction in MDCKII and MDR1-MDCKII cells. The permeability coefficients in the BL to AP direction were significantly higher in MDCKII cells overexpressing PgP. These findings indicate that CTS is a substrate for PgP that can pump CTS into the luminal side.

Issues in the implementation of cross-cultural management in Australia-evidence from a study of selected public and private sector organisations

This study examines the current status of cross-cultural management (CCM) in Australia.

The study is based on Reyes' (2004) Ph.D research of a qualitative nature in five organisations in the public and private sectors selected from a sample of organisations which appear to lead the field in Australia in respect of CCM. Literature is also surveyed to present a picture of the current legal and institutional setting of CCM in Australia and provide a context for the study.

Analysis of the findings highlights the gap between cross-cultural rhetoric and action in workplace situations. Problems are identified leading to incomplete and inadequate implementation of CCM in the respondent organisations. The study argues for the need for management to take a systems approach to the formulation and implementation of CCM. Some suggestions are made for improvements in the future.

Year 12 students' mental models of the nature of light

This paper reports on the third year of a three-year longitudinal investigation into six Year 10 secondary students’ understanding of optics at a secondary school level. During the first two years of the study the students’ understanding of geometrical optics was explored with the adoption of constructivist teaching and learning strategies. The students' understanding of geometrical optics following the Year 11 teaching stage then formed the basis of exploration of their mental models of the nature of light. This exploration occurred before, during and following a Year 12 teaching stage where the students studied physical optics and quantum ideas. Before the Year 12 teaching stage the students had constructed mental models of light that related to their understanding of a ray. Over the Year 12 teaching stage the students’ mental models changed to conceptualizations of a photon. There was evidence in the students’ mental models of a hybridization of the particle and wave scientific models. That is, they conceptualized the photon as having both wave and particle characteristics. The variation in the students’ hybrid models also suggested a variation in the way they conceived of the nature of scientific models.

Little big boys: a study of peers, power and pedagogy

In this paper we will argue that the dominant discourse on young males 'at risk' focuses too narrowly on the adolescent and young adult years. There is a tendency to individualise, both practically and theoretically, behaviours that are thought to substantiate the application of this category. Against this backdrop, we report on a study undertaken with a group of 6-8 year old boys in a primary school setting. The research was compiled around the interactions of an 'affinity group' of five young males across a six-month period. Prominent in our discussion of this data will be, the contextual nature of behaviour and identity, the influential role of the peer group, and the desire to 'other' in defining the self. We conclude by considering some of the implications this work has for the way mainstream schooling is structured and practiced.

Marketing students' perception of traditional and intensive delivery : an exploratory study

The study investigated how undergraduate marketing students perceived intensive delivery of subjects over summer school as compared to traditional semester delivery. The results suggest that students did not perceive there were substantial differences in learning, but preferred the more intensive nature of the learning. The results also indicate that summer school students found the subject more interesting and rated the subject higher overall as compared with the traditional mode. Individual assessment grades for students in the intensive mode did differ to those in the traditional mode, but examination results and final grades were not statistically different. Intensive modes may be viable alternatives to traditional semester long classes, although they do potentially have increased costs.

Country practice : a case study of regional public relations practice

Research into public relations practice in all settings is vital given the extent and spread of its practice. However, despite the maturity of the public relations profession and the number of public relations practitioners who operate outside metropolitan areas, there has been little research to identify the distinctive nature of public relations practice in regional locations.

This research project begins a dissection of the nature of professional public relations practice in a non-metropolitan setting through the examination of public relations activity, workplaces and interactions in a regional locale. The project seeks to examine the specific nature of public relations practice in non-metropolitan Australia through a case study of two Victorian regional cities; Ballarat and Warrnambool. Analysis of these two sites provides the pilot stage for a larger future comparative examination of public relations practice in regional Australian centres with a variety of economic, demographic and geographic profiles.

What is the on-campus experience? Engineering student study and work

Accreditation for off-campus engineering programmes has proven to be problematic. In Australia, off-campus programmes are compelled to contain mandatory residential sessions so that offcampus students can have an `on-campus experience'. This paper explores the nature of modern oncampus undergraduate engineering study, and finds that it now typically involves at least part-time employment and has more in common with off-campus study than the on-campus experience enjoyed by most of the current institutional (education and professional) administrators when they completed their undergraduate studies. Rather than ignore student term-time work, engineering programmes should use it to enhance the development of desirable graduate attributes.

Diversities in the professional organization of accountants : a comparability study with insights from the Chinese experience

While spatial, historical and cultural variations across different countries have prevented any generalisation to be made of the professionalization process, various analytical themes can be said to have emerged in scholarly inquires relating to the professional organization of accountants. In highlighting these broad themes, this study argues that they have all revolved around one important relationship-that of the state and the accounting profession. The dynamics and the fluid nature of this intriguing relationship is further captured and contrasted in this study through an investigation of an episode of intra-professional conflict during the professionalization experience of the Chinese accountants.

The existence and nature of risk management committees in Australian companies

A risk management committee (RMC), as a newly evolving sub-committee of the board of directors, functions as a key governance support mechanism in the oversight an organisation’s risk management strategies, policies and processes. However, empirical evidence on the factors associated with the existence and the type of RMCs remains scant. Using an agency theory perspective, this study investigates the association between board factors such as proportion of non-executive directors, CEO duality, and board size; as well as, other firm-related factors (e.g. auditor type, industry, leverage, and complexity), and (1) the existence of a RMC, and (2) the type of RMC (namely, a separate RMC versus one that is combined with the audit committee). Data was collected from the annual reports of the top 300 ASX-listed companies. The results, based on logistic regression analyses, indicate that RMCs tend to exist in companies with an independent board chairman and larger boards. Further, the results also indicate that in comparison to companies with a combined RMC and audit committee, those with a separate RMC are more likely to have larger boards, higher financial reporting risk and lower organisational complexity. The findings of this study provide additional information on the use and design of RMCs in a voluntary setting.

Exploring the extent and nature of the diversity of the doctoral population in Australia : A profile of the respondents to a 2005 national survey

Although there is general agreement that diversity is a feature of doctoral education in Australia, there are various forms and levels of diversity, many of which are not captured by analyses that rely on categories for analysing the doctoral education population that are those commonly used in education at the undergraduate level, such as sex, age, mode of study, type of enrolment, citizenship, and Broad Field of Study, etc. These categories primarily reflect concerns to do with funding and issues of participation and equity. Our analysis of data from a national survey of doctoral candidates carried out in 2005 as part of a Linkage Grant project “Reconceptualising the doctoral experience’, suggests that not all of these categories are relevant to critical concerns for doctoral education. Nor do analyses at a macro-level represent the particularity of the doctoral experience. They can mask the reality of a highly variable student population, and one that is not necessarily represented accurately or helpfully by ascribing group identities.

Teaching and learning force as a representational issue : insights from a classroom video study

An enormous amount of research in the conceptual change tradition has shown the difficulty of learning fundamental science concepts, yet conceptual change schemes have failed to convincingly demonstrate improvements in supporting significant student learning. Recent work in cognitive science has challenged this purely conceptual view of learning, emphasising the role of languages, and the importance of personal and contextual aspects of  understanding science. The research described in this paper is designed around the notion that learning involves the recognition and development of students’ representational resources. In particular, we argue that difficulties with the concept of force are fundamentally representational in nature. The paper describes the planning and implementation of a classroom sequence in force that focuses on representations and their negotiation, and reports on the effectiveness of this perspective in guiding teaching and learning. Classroom sequences involving three teachers 158 2008 NARST Annual International Conference were videotaped using a combined focus on the teacher and groups of students. Video analysis software was used to code the variety of representations used, and sequences of representational negotiation. Stimulated recall interviews were conducted with teachers and students. The paper will report on the effect of this approach on teacher knowledge and pedagogy, and on student learning of force.

Health care provider and consumer understandings of cultural safety and cultural competency in health care : an Australian study

There is increasing recognition in Australia that racial and ethnic minority groups experience significant disparities in health and health care compared with the average population and that the Australian health care system needs to be more responsive to the health and care needs of these groups. The paper presents the findings of a year long study that explored what providers and recipients of health care know and understand about the nature and implications of providing culturally safe and competent health care to minority racial and ethnic groups in Victoria, Australia. Analysis of the data obtained from interviewing 145 participants recruited from over 17 different organizational sites revealed a paucity of knowledge and understanding of this issue and the need for a new approach to redress the status quo.

A prospective study of overweight, physical activity and depressive symptoms in young women

This study examined the prospective associations of BMI, physical activity (PA), changes in BMI, and changes in PA, with depressive symptoms. Self-reported data on height, weight, PA, selected sociodemographic and health variables and depressive symptoms (CESD-10) were provided in 2000 and 2003 by 6,67 young adult women (22–27 years in 2000) participating in the Australian Longitudinal Study on Women's Health (ALSWH). Results of logistic regression analyses showed that the odds of developing depressive symptoms at follow-up (2003) were higher in women who were overweight or obese in 2000 than in healthy weight women, and lower in women who were active in 2000 than in sedentary women. Changes in BMI were significantly associated with increased odds of depressive symptoms at follow-up. Sedentary women who increased their activity had lower odds of depressive symptoms at follow-up than those who remained sedentary. Increases in activity among initially sedentary young women were protective against depressive symptoms even after adjusting for BMI changes. These findings indicate that overweight and obese young women are at risk of developing depressive symptoms. PA appears to be protective against the development of depressive symptoms, but does not attenuate the depressive symptoms associated with weight gain. However, among initially sedentary young women, even small increases in PA over time may reduce the odds of depressive symptoms, regardless of weight status.
