Identification of incident fractures : the Geelong Osteoporosis Study

Background: Complete fracture ascertainment is critical for fracture cost estimates and planning for future health care facilities. Virtually complete ascertainment is possible for hip fractures because they nearly always require hospitalisation.

Aims: To validate the use of radiological reports as a resource for ascertaining fracture cases, using hip fracture as a model.

Methods: Hip fracture rates obtained from radiological reports were compared with rates obtained from hospital discharge summaries of medical records using International Classification of Diseases-9 (ICD-9) codes 820.0–820.9 and 733.1 over a three-year period.

Results: Hip fracture cases numbered 589 using radiological reports and 585 using medical records. Discharge summaries failed to identify 15 cases ascertained through radiology reports whereas 11 cases ascertained through medical records were not identified from X-ray reports. The age-specific incidence rates for radiological ascertainment were within the 95% confidence limits of the rates derived from medical records.

Conclusions: Among a population of patients generally admitted to hospital for treatment of their fracture, we were able to identify more cases from radiological reports than from medical records. Incidence rates for hip fracture were comparable using the two methods. Radiological reports provide a valuable resource for identifying incident fractures. This method of case ascertainment would be suitable for identifying both major and minor fractures in regions with self-contained health services where access to all radiological reports is possible.

Building genetic networks using relatedness information : a novel approach for the estimation of dispersal and characterization of group structure in social animals

Natal dispersal is an important life history trait driving variation in individual fitness, and therefore, a proper understanding of the factors underlying dispersal behaviour is critical to many fields including population dynamics, behavioural ecology and conservation biology. However, individual dispersal patterns remain difficult to quantify despite many years of research using direct and indirect methods. Here, we quantify dispersal in a single intensively studied population of the cooperatively breeding chestnut-crowned babbler (Pomatostomus ruficeps) using genetic networks created from the combination of pairwise relatedness data and social networking methods and compare this to dispersal estimates from re-sighting data. This novel approach not only identifies movements between social groups within our study sites but also provides an estimation of immigration rates of individuals originating outside the study site. Both genetic and re-sighting data indicated that dispersal was strongly female biased, but the magnitude of dispersal estimates was much greater using genetic data. This suggests that many previous studies relying on mark–recapture data may have significantly underestimated dispersal. An analysis of spatial genetic structure within the sampled population also supports the idea that females are more dispersive, with females having no structure beyond the bounds of their own social group, while male genetic structure expands for 750 m from their social group. Although the genetic network approach we have used is an excellent tool for visualizing the social and genetic microstructure of social animals and identifying dispersers, our results also indicate the importance of applying them in parallel with behavioural and life history data.

What does a museum mean? A narrative approach to museum impact

This paper presents ‘narrative’ as a theoretically informed qualitative perspective to explore and substantiate such abstract concept as ‘museum impact’. It argues that the impact of museums is best understood via the meanings visitors make and negotiate in the long-term. This provides critical insights into what a museum visit means and how its impact is negotiated within time and space. I lay out the theoretical rationale and methodological approach for the research project underpinning this paper while future publications will provide empirical findings and theoretical conclusions.

Antecedents and consequences of service quality in a higher education context : A qualitative research approach

Purpose – The purpose of the paper is to report on the perception of students in regard to critical antecedents, dimensions and consequences of service quality with an aim to develop a theoretical model in the context of a university in Australia.

Design/methodology/approach – This research used focus group discussions with 19 students who had been studying in undergraduate and postgraduate level programs at an Australian university.

Findings – The findings show that the critical antecedents to perceived service quality are information and past experience. There are three aspects of perceived service quality, namely, academic, administrative and facilities. Student satisfaction and student trust are found to have direct and positive relationships with perceived service quality as consequences; and brand performance and behavioural intention are found to have indirect relationships with perceived service quality mediated through satisfaction and trust.

Originality/value – This paper found three separate themes and their relationships with service quality in the context of a university. These themes are: information, past experience and brand performance. Perceived service quality was found playing an important role in this theoretical model. The model provides a good explanation of university brand performance and students' behavioural intentions.

A generalised data analysis approach for baggage handling systems simulation

Airport baggage handling systems are a critical infrastructure component within major airports, and essential to ensure smooth luggage transfer while preventing dangerous material being loaded onto aircraft. This paper proposes a standard set of measures to assess the expected performance of a baggage handling system through discrete event simulation. These evaluation methods also have application in the study of general network systems. Results from the application of these methods reveal operational characteristics of the studied BHS, in terms of metrics such as peak throughput, in-system time and system recovery time.

The problem of underachievement in numeracy : using bourdieu and critical theory to interpret academic achievement

The paper considers the achievement gap experienced by Victorian public school students. The paper uses a methodological approach informed by critical theory to interpret achievement levels between students from high and low socio-economic status. It analyses and discusses documented data and in doing this, reflects upon the work of Bourdieu emphasizing the reproductive nature of contemporary schooling. 

EPODE approach for childhood obesity prevention : methods, progress and international development

Childhood obesity is a complex issue and needs multistakeholder involvement at all levels to foster healthier lifestyles in a sustainable way. ‘Ensemble Prévenons l'ObésitéDes Enfants’ (EPODE, Together Let's Prevent Childhood Obesity) is a large-scale, coordinated, capacity-building approach for communities to implement effective and sustainable strategies to prevent childhood obesity. This paper describes EPODE methodology and its objective of preventing childhood obesity.

At a central level, a coordination team, using social marketing and organizational techniques, trains and coaches a local project manager nominated in each EPODE community by the local authorities. The local project manager is also provided with tools to mobilize local stakeholders through a local steering committee and local networks. The added value of the methodology is to mobilize stakeholders at all levels across the public and the private sectors. Its critical components include political commitment, sustainable resources, support services and a strong scientific input – drawing on the evidence-base – together with evaluation of the programme.

Since 2004, EPODE methodology has been implemented in more than 500 communities in six countries. Community-based interventions are integral to childhood obesity prevention. EPODE provides a valuable model to address this challenge.

Consideration of multiple template switches is critical to the determination of the recombination rate on the HIV genome

Retroviral recombination drives viral diversity and facilitates the emergence of immune escape and drug resistant mutants that contribute to disease progression. Current estimates of retroviral recombination rates are based on indirect measurements that do not take into account the effects of multiple recombination events. In the presence of multiple template switches, any even number of template switches result in no observed recombination and any odd number is detected as a single recombination event. We demonstrate that ignoring multiple recombination events consistently underestimates the true recombination rate, especially over large genetic distances and high rates of recombination. Here, we present a novel approach to measure rates of recombination across different gene segments regardless of the effects of genetic distance and the overall rate of recombination. We apply these tools to a novel HIV-1 marker system, which mimics the recombination process between closely related genomes, analogous to those found within the quasispecies of an infected individual. We directly measure the recombination rate in gag, correcting for the effects of multiple template switches and background recombination. Furthermore, our analysis indicates that recombination rates are likely to vary across the viral genome. This system is applicable to other studies to accurately measure the recombination rate that is critical for the diversification of retroviruses.

Critical pre-implementation elements in engendering change for sustainability in SMEs : insights from SME sustainability leaders

Despite the increased awareness surrounding sustainability issues and growing pressure on businesses to adopt sustainable business practices, there is little understanding of management processes and practices necessary for SMEs to implement environmental sustainable (ES) practices. Through qualitative in-depth interviews, this paper draws on the experiences and perspectives from twelve SME sustainability leaders to present answers to the 'what' and 'why' of critical pre-implementation elements in engendering change for sustainability within the SME context. The research questions examined in this study are: In the views of SME sustainability leaders: what pre-implementation elements are important in setting the foundations of ES success in SMEs; what are the most important elements in the decision to introduce and encourage improved ES practices; and how do SME sustainability leaders plan for ES change in their firms. We also examine how the pre-implementation elements identified in this study, fit with the steps of one of the most well-known sustainability change management frameworks by Dunphy et al (2003). The results show that elements playing a role in setting the foundations for ES success in participating firms include: the SME leader challenging the status quo, gathering of initial information; clarifying the internal know-how about ES, identifying who the ES leader(s) is, and what the associated roles are; creating a theme of environmental sustainability in the firm (what sustainability means to the firm); and the personal mindset of leaders regarding ES. In addition, it was evident from the interview data that apart from providing valuable data regarding what must change and why, the drivers and benefits of ES provide a strong rationale and motivation to the rest of the organisation why sustainability is important to the organisation. Furthermore, it is evident from the interview data that the most used strategic approach to planning by SME sustainability leaders, is a deliberate approach even though the emergent approach to planning has also featured in some SMEs. Furthermore, the CEOs are the main players in the strategic process, with the majority involving staff in planning for ES. The results also indicate that in matching the pre-implementation elements to Dunphy et al‘s (2003) sustainability change management steps, the execution of two of their steps may need adjustment to be fully applicable to SMEs. Several practical implications for other SMEs are outlined. In conclusion, the framework outlined in this paper provides an example of a critically reflective approach to a specific phase of the environmental sustainability puzzle in SMEs.

Review of nursing care for patients undergoing percutaneous coronary intervention: a patient journey approach

Aim.  To evaluate the existing literature to inform nursing management of people undergoing percutaneous coronary intervention. Background.  Percutaneous coronary intervention is an increasingly important revascularisation strategy in coronary heart disease management and can be an emergent, planned or rescue procedure. Nurses play a critical role in delivering care in both the independent and collaborative contexts of percutaneous coronary intervention management. Design.  Systematic review. Method.  The method of an integrative literature review, using the conceptual framework of the patient journey, was used to describe existing evidence and to determine important areas for future research. The electronic data bases CINAHL, Medline, Cochrane and the Joanna Briggs data bases were searched using terms including: (angioplasty, transulminal, percutaneous coronary), nursing care, postprocedure complications (haemorrhage, ecchymosis, haematoma), rehabilitation, emergency medical services (transportation of patients, triage). Results.  Despite the frequency of the procedure, there are limited data to inform nursing care for people undergoing percutaneous coronary intervention. Currently, there are no widely accessible nursing practice guidelines focusing on the nursing management in percutaneous coronary intervention. Findings of the review were summarised under the headings: Symptom recognition; Treatment decision; Peri-percutaneous coronary intervention care, describing the acute management and Postpercutaneous coronary intervention management identifying the discharge planning and secondary prevention phase. Conclusions.  Cardiovascular nurses need to engage in developing evidence to support guideline development. Developing consensus on nurse sensitive patient outcome indicators may enable benchmarking strategies and inform clinical trial design. Relevance to clinical practice.  To improve the care given to individuals undergoing percutaneous coronary intervention, it is important to base practice on high-level evidence. Where this is lacking, clinicians need to arrive at a consensus as to appropriate standards of practice while also engaging in developing evidence. This must be considered, however, from the central perspective of the patient and their family.

Temporal patterning of competitive emotions : a critical review

An interactional model of stress that integrates current research on competitive affects and emphasizes the temporal dimensions of the stress process is forwarded. The literature reveals that the study of athletes' affective responses to competition has been narrowly focused on pre-competitive anxiety. Equivocal findings on temporal patterning of competitive anxiety suggest that a fundamental change in the empirical approach is needed because the current conceptualization of anxiety and other complex emotions is imprecise. The analysis of secondary emotions as patterns of discrete basic emotions, as suggested by differential emotions theorists, is proposed for consideration in future research. In this view, competitive anxiety is considered as a set of patterns of emotions rather than a unitary affect. The adoption of this approach could result in better operationalization of competitive anxiety as well as other secondary performance-related emotions. We propose that research on competitive affects should follow two parallel lines. The first should focus on the description of complex emotional states that reflect the idiosyncratic emotional experience and vocabulary of the athlete. The second should examine the sets of basic emotions experienced throughout competition, and focus on individual differences and factors determining those differences. The integration of the two approaches could lead to a better understanding of whether, how and why individuals differ in the interpretation of specific secondary emotions and their effect on performance. Moreover, it would permit the analysis of intra-individual variations in labelling secondary emotions with respect to different competitive contexts and temporal aspects.

A critical review of psychological instruments used in police officer selection

Purpose
The purpose of this paper is to critically examine the instruments used in the screening process, with particular attention given to supporting research validation. Psychological screening is a well-established process used in the selection of employees across public safety industries, particularly in police settings. Screening in and screening out are both possible, with screening out being the most commonly used method. Little attention, however, has been given to evaluating the comparative validities of the instruments used.

Design/methodology/approach
This review investigates literature supporting the use of the Minnesota Multiphasic Personality Inventory (MMPI), the California Personality Inventory (CPI), the Inwald Personality Inventory (IPI), the Australian Institute of Forensic Psychology's test battery (AIFP), and some other less researched tests. Research supporting the validity of each test is discussed.

Findings
It was found that no test possesses unequivocal research support, although the CPI and AIFP tests show promise. Most formal research into the validity of the instruments lacks appropriate experimental structure and is therefore less powerful as “evidence” of the utility of the instrument(s).

Practical implications
This research raises the notion that many current screening practices are likely to be adding minimal value to the selection process by way of using instruments that are not “cut out” for the job. This has implications for policy and practice at the recruitment stage of police employment.

Originality/value
This research provides a critical overview of the instruments and their validity studies rather than examining the general process of psychological screening. As such, it is useful to those working in selection who are facing the choice of psychological instrument. Possibilities for future research are presented, and development opportunities for a best practice instrument are discussed.

A sophistic rhetorical approach to public relations

This article introduces a thesis that understanding rhetoric properly will lead to the best way of understanding public relations properly. It acknowledges but then critiques Robert Heath’s advocacy of the rhetorical paradigm. It also acknowledges the more critical contributions to the rhetorical theory of public relations of Jacquie L’Etang, Øyvind Ihlen, Andrej Skerlap and Lee Edwards. However in declining to favour the approaches of any of these authors it argues that no writers have so far revealed the true significance of a proper application of the notion ‘rhetoric’ to the field of public relations. The claim will be that if the true relevance of the fields of public relations and rhetoric to each other is fully recognised the stature of public relations would be raised to a considerable extent beyond current thinking.

Evaluating the intertwined critical success factors for sustainable e-learning

Successfully leveraging knowledge transfer in distributed e-learning requires effective combination of pedagogies, technologies, and efficient management of learning resources. As a result, identifying and evaluating the critical success factors within each of these facets is vital for the success of e-learning. This paper explores the critical success factors intertwined within the learning ecosystem namely pedagogy, technology and management of learning resources in a higher education e-learning environment. Adopting a hybrid approach consisting of a systematic literature review and interviews with experts in e-learning, this paper shows that there is a discrepancy between theory and practice in e-learning in regard to the application of pedagogies, use of technology, and management of reusable learning objects. This implies that there is a need for tackling various issues regarding the adoption of appropriate e-learning strategies, knowledge sharing, quality, granularity and reusability of learning object for sustainable e-learning.
