Postdeconstruction-reconstruction of journals as a methodological solution for the postmodern researcher

Many in the postmodern era recognise the subjectivity of the research process and in doing so seek to dismantle the traditional barrier between the researcher and the researched. How may the standpoint of this research subject be incorporated? How may this be implemented in practical terms? And how may this be analysed without theoretical recourse to essentialism? This paper proposes a new application of journalling to solve these methodological dilemmas drawing on a wider research project that investigates how practitioners conceptualise and enact policy reform. Responses to related postmodern methodological dilemmas and solutions will be invited from conference discussants.

Emerging methodological issues in environmental education research

This presentation draws on recent experience in the “Environment and School Initiatives” (ENSI) project to explore emerging issues in the methodology of action research in environmental education. The ENSI project has been operating for close to twenty years, involving some twenty (mainly European) countries in the conduct and reporting of attempts to adopt an action research perspective in environmental education curriculum development and professional development. The presentation will locate the project within an historical perspective on research in environmental education before considering differing interpretations of the action research methodology in a range of different (country-based) professional settings. With examples from case studies of action research in environmental education, the presentation suggests that action research is best characterised by adoption of certain principles such as deliberate reflection by practitioners, respect for „practical knowledge‟ of teachers and teacher-generated narrative data, and recognition of the significance of context, rather than by adherence to any recipe-like methodological formula. A corollary of this is that methodologists need to acknowledge and respect the „exigencies of practice‟ within which practitioners of action research in environmental education conduct their professional work.

The effects of clustered data on standard error estimates in covariance structure analysis : a field data application

Purpose – The purpose of this article is to present an empirical analysis of complex sample data with regard to the biasing effect of non-independence of observations on standard error parameter estimates. Using field data structured in the form of repeated measurements it is to be shown, in a two-factor confirmatory factor analysis model, how the bias in SE can be derived when the non-independence is ignored.

Design/methodology/approach – Three estimation procedures are compared: normal asymptotic theory (maximum likelihood); non-parametric standard error estimation (naïve bootstrap); and sandwich (robust covariance matrix) estimation (pseudo-maximum likelihood).

Findings – The study reveals that, when using either normal asymptotic theory or non-parametric standard error estimation, the SE bias produced by the non-independence of observations can be noteworthy.

Research limitations/implications – Considering the methodological constraints in employing field data, the three analyses examined must be interpreted independently and as a result taxonomic generalisations are limited. However, the study still provides “case study” evidence suggesting the existence of the relationship between non-independence of observations and standard error bias estimates.

Originality/value – Given the increasing popularity of structural equation models in the social sciences and in particular in the marketing discipline, the paper provides a theoretical and practical insight into how to treat repeated measures and clustered data in general, adding to previous methodological research. Some conclusions and suggestions for researchers who make use of partial least squares modelling are also drawn.

Patients' experiences of cardiology procedures using minimal conscous sedation

Aim: The study's purpose was to describe patients' experiences of minimal conscious sedation during diagnostic and interventional cardiology procedures.

Methods: Over a 6-week period, 119 consecutive patients (10% of annual throughput) from a major metropolitan hospital in Melbourne, Australia, were interviewed using a modified version of the American Pain Society Patient Outcome Questionnaire. Patients identified pain severity using a 10-point visual analogue scale and rated their overall comfort on a 6-point Likert scale ranging from very comfortable to very uncomfortable.

Results: Patients were aged 67.6 years (standard deviation 11.1), 70.8% were male, and the mean body mass index was 27.7 (standard deviation 4.8). Patients underwent diagnostic coronary angiography (67.5%), percutaneous coronary interventions (13.3%), or combined procedures (19.2%). Most patients (65%) were comfortable in the context of low-dose conscious sedation. Slight discomfort was reported by 26% of patients; 9% reported feeling uncomfortable primarily as a result of a combination of musculoskeletal pain, angina, and vasovagal symptoms experienced during the procedure. There was significant correlation (rho = .25, P = .01) between procedure length and patients' report of overall comfort, suggesting longer procedures were less comfortable for patients.

Conclusions: The minimal sedation protocol was effective for the majority of patients; however, 9% of patients experienced significant discomfort related to preexisting conditions, highlighting the need for individual patient assessment before, during, and after the procedure.

Risk management and ethical environment : effects on internal audit and accounting control procedures

This study examines the impact of the scope of risk management and ethical environment on internal audit activities and the quality of accounting control procedures (ACPQ). The conceptual framework for the study is guided by COSO’s frameworks on internal controls and enterprise risk management and data from a questionnaire survey of 64 Australian firms are analysed using a structural equation model. The results of the study support that (1) internal audit activities have a significant intervening effect on the relationship between the scope of risk management and ACPQ, and (2) a direct and positive relationship exists between ethical environment and ACPQ. Our findings suggest that widening the scope of risk management activities do not directly improve ACPQ, but that it leads to more extensive internal audit activities and in turn such activities promote better ACPQ. Further, the results indicate that fostering a more ethical environment directly leads to higher ACPQ. These results have implications for the design of internal controls, namely with respect to the role of internal audit activities and ethical environment in enhancing ACPQ.

Nutrition screening in long-term care facilities : an evaluation of the methodological quality of available instruments

A variety of nutrition screening instruments have been developed and implemented for identifying the risk of undernutrition among community and hospitalized older adults. Despite the high prevalence of undernutrition amongst older adults in long-term care, few screening instruments have been developed or evaluated in this setting. This review aims to evaluate the validity, reproducibility and feasibility of nutrition screening instruments developed for use, or described as being used, with older adults in long-term care. Ten publications encompassing nine independent nutrition screening tools were identified using electronic databases and manual searches of reference lists. The Mini Nutritional Assessment-Short Form (MNA-SF) was the most widely evaluated nutrition screening instrument and met the requirements for a valid instrument (sensitivity and specificity >0.9) for use in the long-term care setting. Modified versions of the MNA for use in China and South Africa also demonstrated acceptable levels of sensitivity and specificity. Other nutrition screening instruments were found to have variable levels of sensitivity and specificity and while some demonstrated levels consistent with the MNA-SF, only two were evaluated across more than one study population, Body Mass Index (BMI)+weight loss and BMI+albumin. These same instruments reported the highest levels of inter-rater and test-retest reproducibility, although this was only tested in one other instrument (Chinese Nutrition Screen -modified MNA). In conclusion, it is evident from this review that further work in this area is needed. Based on validity, reproducibility and feasibility it appears that BMI+weight loss is the most suitable nutrition screening instrument for use in the long-term care setting at this time. MNA-SF is promising; however, there is currently no data for inter-rater or test-retest reproducibility in the long-term care setting.

Quality of internal control procedures : antecedents and moderating effect on organisational justice and employee fraud

Purpose – This study aims to bring together theoretical concepts from the organizational justice, internal control and fraud literature to develop two distinct models relating to employee fraud and the quality of internal control procedures (ICP), respectively.

Design/methodology/approach – Survey data from 64 Australian firms were used to develop the two models. The first model was tested using a logistic regression analysis, and the second model was tested using a multiple regression analysis.

Findings – The first model reveals that the quality of ICP has a moderating effect on the relationship between perceptions of organizational justice and employee fraud. The second model indicates that ICP quality is significantly and positively related to three key organizational factors: the corporate ethical environment, the extent of risk management training of staff, and the internal audit (IA) activity level.

Practical implications – Risk management strategies relating to employee fraud will need to pay greater attention to organizational factors that affect both perceptions of justice at the workplace and ICP quality, including fostering a more ethical and equitable work environment, increasing IA activities and staff training in risk management.

Originality/value – Using the fraud triangle framework, this study extends previous literature by providing empirical evidence on the role of organizational justice and ICP regarding employee fraud.

Longitudinal studies into science learning - methodological issues

The Gold Standard for education research promotes randomized controlled trials (RCTs) that can produce generalizable knowledge claims across similar problems and situations. Unfortunately, the Gold Standard does not fully recognize the need for developmental research to better understand the problem space, formulate theory and approaches to teaching and learning, and formulate and pursue associated research questions. This developmental research has been a precursor to the development of interventions together with the necessary instrumentation and technologies required to fully investigate these through the more formal evaluative processes imagined by the Gold Standard. This chapter focuses on longitudinal studies that cover a continuum from such developmental research to research that uses control-experimental features to evaluate interventions. These studies attend to a set of issues dealing with  developmental progressions and learning trajectories that require  investigation over an extended period of time. It will be argued that
these longitudinal studies of a variety of methodological types represent quality research in that rigorous design and implementation produce  evidence-based claims. The chapter examines the nature of the relationship between evidence and claims in these studies, to show the possibility of building in control features every bit as strong as those in classic Gold Standard designs. Further, it will be argued that, given the complexity of learning pathways, a simplistic interpretation of RCTs conducted over the shorter term can be misleading in terms of both internal and external validity claims.

The second curriculum opera : Arias, assessment and methodological traces

Drawing on contemporary forms of qualitative research such as performance ethnography (McCall, 2000), autoethnography (Ellis & Bochner, 2000; Ellis & Flaherty, 1992) and using narrative and writing as forms of inquiry (Richardson, 1990; 1992; 1995a; 1995b; 1997; 1999; 2000), this research project constructs a 'learning through' (Gardner, 1983; 1993; 1995; 1999; 2003a; 2003b) approach to curriculum within pre-service teacher education. During 2002 we initiated the first curriculum opera (Dixon & White, 2003; Dixon, White, & Smerdon, 2003) in our Faculty of Education with thirty-seven students. In 2003 we developed this learning and teaching approach with twice as many students. We also reconsidered assessment of students involved in the opera for overall theoretical consistency. As students increasingly took control, they 'imagined curriculum' (Doll & Gough, 2002) and transformed their exploration of identity in the 'process of becoming' teachers (Britzman, 2003). In this paper, we outline the project and the learning involved. We also indicate future directions for learning and teaching in preservice teacher education as well as the potential uses and misuses of teacher assessment through portfolio.

The optimisation of ultrasonic cleaning procedures for dairy fouled ultrafiltration membranes

Ultrafiltration (UF) of whey is a major membrane based process in the dairy industry. However, commercialization of this application has been limited by membrane fouling, which has a detrimental influence on the permeation rate. There are a number of different chemical and physical cleaning methods currently used for cleaning a fouled membrane. It has been suggested that the cleaning frequency and the severity of such cleaning procedures control the membrane lifetime. The development of an optimal cleaning strategy should therefore have a direct implication on the process economics. Recently, the use of ultrasound has attracted considerable interest as an alternative approach to the conventional methods. In the present study, we have studied the ultrasonic cleaning of polysulfone ultrafiltration membranes fouled with dairy whey solutions. The effects of a number of cleaning process parameters have been examined in the presence of ultrasound and results compared with the conventional operation. Experiments were conducted using a small single sheet membrane unit that was immersed totally within an ultrasonic bath. Results show that ultrasonic cleaning improves the cleaning efficiency under all experimental conditions. The ultrasonic effect is more significant in the absence of surfactant, but is less influenced by temperature and transmembrane pressure. Our results suggest that the ultrasonic energy acts primarily by increasing the turbulence within the cleaning solution.
