Easier analysis and better reporting : modelling ordinal data in mathematics education research

This article presents an examination of the use of Rasch modelling in a major research project, 'Improving Middle Years Mathematics and Science' (IMYMS). It is unarguable that it is important to take students' perceptions, or views, into account when planning learning and teaching for them. The IMYMS student perceptions survey is an attempt to make visible these student viewpoints, and report them in a way that is accessible to teachers and researchers involved in the project. The project involves four clusters of schools from urban and regions of Victoria to investigate the role of mathematics and science knowledge and subject cultures in mediating change processes in the middle years of schooling. There are five secondary and twenty-eight primary schools. The project has generated both qualitative and quantitative data, with much of the qualitative data being ordinal in nature. Reporting the results of analyses for a range of audiences necessitates careful, well-designed report formats. Some useful new report formats based on Rasch modeling -the Modified Variable Map, the Ordinal Map, the Threshold Map, and the Annotated Ordinal Map - are illustrated using data from the IMYMS project. The Rasch analysis and the derived reporting formats avoid the pitfalls that exist when working with ordinal data and provide insights into the respondents' views about their experiences in schools unavailable by other approaches.

Environmental reporting initiatives: towards triple-bottom line reporting or the intergration of financial and environmental performance

This objective of this study was to investigate the quantity and quality of voluntary environmental disclosures in the annual reports of the top 500 firms listed by market capitalisation on the Australian Stock Exchange. The periods examined were those immediately prior and subsequent to the release of the Exposure Draft Coalition for Environmentally Responsible Economics (CERES) Global Reporting Initiatives(GRI) issued in March 1999. Using content analysis to focus on the environmental aspects, and drawing heavily on the research of Gamble et al (1995), the study compared 425 annual reports over a two year period and 60 environmental reports, in order to explore reporting practices in the periods surrounding this intervention. The results suggest a trend to triple bottom reporting, and a significant change in the quality and quantity of environmental information, albeit in specific categories.

Environmental and social responsibility: a normative financial reporting concept

The inclusion of environmental and social values in a firm’s policy and key performance indicators can enhance its reputation and create wealth for both the firm and its investors. Social values and associated activities are initially integrated with financial resources through the strategic plan, which requires firms to merge the longer term environmental and social values with short term economic objectives and performance measures. Strategies will differ between individual corporations. This paper provides a normative reporting concept which connects the financial implications associated with longer term planning for environmental and social values, with short term accounting reports. Reporting variants adapted from total cost assessment, life cycle costing, variable costing are integrated to offer opportunities to present both past and predicted information based on a product segment view.

Who speaks on footballers and sexual assault? A gender analysis of sports reporting

The recent spate of sexual assault allegations made against Australian Football League (AFL) players has generated intense media scrutiny and public concern. Following from similar highly publicised allegations directed at the National Rugby League, these incidents have engendered significant debates around sexism and football culture in the popular press. It is the media’s response to allegations of sexual assault made against AFL footballers that will be analysed here. This study offers a content analysis of articles from the sport sections of two major Australian newspapers, The Age and the Herald-Sun, with the aim of assessing the prevalence of women’s perspectives on the issue of player misconduct and whether the gender of the reporter has any bearing on gender stereotyping in sport reporting. By assessing how the phenomenon of player misconduct has been covered in sport news, this paper evaluates the media’s role in changing dominant attitudes and perceptions of gender relations in Australian society.

Program assessment and reporting: linking people, processes and data

As part of a larger Simplification Project for program quality assurance processes conducted at RMIT University, this paper chronicles the refinement of one aspect: program assessment and reporting. This involved the realignment of criteria used in program quality assurance with those developed in higher-level strategic and business planning processes. In addition, the project attempted to address the lack of alignment between annual program processes and subsequent decisions made about the future of programs, particularly in profile planning processes.
A revised Program Annual Report process was developed that aimed to achieve simplicity and alignment while re-engaging program leaders and heads of schools with the quality agenda. A concerted effort was made to develop a process that improved on previously poor vertical communication inherent in program quality assurance. This paper explores the ways in which this was achieved by a) linking people to data through the use of agreed and contextualised performance indicators, and b) linking people to process through more meaningful input into planning and opportunity for dialogue.

What makes a good investigative interviewer of children? A comparison of police officers' and experts; perceptions

Purpose – The purpose of this paper is to examine police officers’ perceptions about their role in interviewing children, and to compare these perceptions with those of child eyewitness memory experts.

Design/methodology/approach – A diverse sample of 23 police officers (from three states of Australia) individually participated in in-depth interviews where they were asked to define what makes a good interviewer in the area of child abuse investigation.

Findings – Irrespective of the background of the officers, the important role of interviewers’ personal attributes was emphasised (e.g. having a relaxed, empathetic, warm nature). Such personal attributes were more prominent in the participants’ descriptions than knowledge of legislation and children’s
development, prior job experience, and interviewing techniques.

Research limitations/implications – The paper shows that while child eyewitness memory experts acknowledge the importance of establishing a bond of mutual trust between the interviewer and the child, the importance of utilising an open-ended questioning style for enhancing rapport, and
for eliciting a detailed and accurate account of abuse cannot be overstated. The possible reasons for the police officers’ emphasis on personal qualities are discussed.

Originality/value – This paper has revealed that limitations in the competency of police officers in interviewing children is not merely a problem of “doing” (i.e. learning to ask open-ended questions),
but may also reflect ingrained attitudinal and organisational barriers.

Guide to questioning children during the free-narrative phase of an investigative interview

The inability of professionals to maintain the use of open-ended questions in the free-narrative phase of investigative interviews with children has been a major problem around the globe. The current paper addresses this concern by describing the key principles underlying the elicitation of free-narrative accounts and practical suggestions for formulating questions. The paper focuses on interviewing children in the early- and middle-childhood years and commences with a definition of the term “free-narrative account” and a description of how such accounts typically develop in children. A description is then provided of the four key characteristics of a good question in the free-narrative interview phase. These include (a) simple language, (b) absence of specific details or coercive techniques, (c) flexibility on the part of the interviewee to choose what details will be reported, and (d) encouragement of an elaborate response. Finally, the process of eliciting a narrative account is briefly described, including examples of questions that adhere to the four characteristics listed above.

Environmental reporting in annual reports: an examination of Australian state government departments

The nature and extent of environmental reporting within the annual reports of four Australian state government departments over a six year period from 2000-2006 is examined in this study. The Victorian Government Department of Sustainability and Environment (DSE), the New South Wales Department of Energy, Utilities and Sustainability (DEUS), the South Australian Department for Environment and Heritage (DEH) and the Tasmanian Department of Primary Industries, Water and Environment (DPIWE) have been selected. These departments are responsible for environmentally sensitive areas such as conservation, water management and public land management. The nature of these areas is a factor which might potentially affect disclosure practices so it might be expected that these departments disclose more environmental information than departments in less environmentally and politically sensitive areas. These departments also have a number of politically active stakeholder groups, including Aboriginal communities and organisations, environmental groups and forest and timber industries. This study found a reduction in environmental reporting after a five year period of increases.

Under-reporting of energy intake in the 1997 national nutrition survey

Aims To estimate the level of under-reporting of energy intake by gender, age, ethnicity and body size (normal, overweight, obese) in the 1997 National Nutrition Survey (NNS97) in New Zealand.
Methods Data were from 4,258 participants (1,808 men and 2,450 women aged 15 years and over) who completed the 24-hour diet recall; the primary methodology used in the NNS97. Under-reporting was assessed using the ratio of reported energy intake to estimated resting metabolic rate (EI: RMRest). Cut-off limits were used to identify percentages of under-reporters in the various subgroups.
Results Mean EI: RMRest was 1.40 for all participants (1.51 for men, 1.30 for women, p<0.001) with older age being associated with lower EI: RMRest (p<0.001). There were no significant differences in mean EI: RMRest between ethnic groups for men.
Mean EI: RMRest for women were: Maori 1.46, European 1.29, and Pacific 1.37 (p<0.01). A larger body size was associated with a significantly lower EI: RMRest especially for women.
Percentages of ‘definite’ under-reporters (individual EI: RMRest <0.9) were as follows: men 12%, women 21%; Europeans 16%, Maori 23% and Pacific 26%; normal weight (11%), overweight (19%) and obese (27%) participants; and from 10% in the youngest to 23% in the oldest age group (p<0.001 for all results).
Conclusion In this study, in agreement with the literature, women, older people and obese people under-reported more than men, younger people and non-obese people. Possible ethnic differences in under-reporting rates need further study. Care is needed in interpreting the energy intake data from the NNS97.
