The aim of this article is to contribute to the development of our understanding of two aspects of attitude change in Australia. First, both cohort and individual explanations for attitude change are tested empirically. Second, empirical evidence is provided about the nature and scope of change in gender role attitudes amongst males and females, and of different birth cohorts in Australia, as reported in two survey periods: 1994 and 2002. In particular, the question of whether there is empirical evidence of cohort differences in attitudes to gender roles in Australia is investigated. TheThe aim of this article is to contribute to the development of our understanding of two aspects of attitude change in Australia. First, both cohort and individual explanations for attitude change are tested empirically. Second, empirical evidence is provided about the nature and scope of change in gender role attitudes amongst males and females, and of different birth cohorts in Australia, as reported in two survey periods: 1994 and 2002. In particular, the question of whether there is empirical evidence of cohort differences in attitudes to gender roles in Australia is investigated. The findings show that birth cohorts display progressively more modern attitudes, but people tend not to change their attitudes as they get older. In addition, men and women have different attitudes to gender roles, with men displaying more traditional beliefs than women. Having more than one child makes women less inclined to express the belief that women should work.

The Australian market research industry relies on telephone interviewing as one of its major data collection methods. Through Its LIST initiative, the industry has committed to best practice In research methods in order to address various concerns, especially the decline in response rates for telephone interviews. Response rates are determined by the co-operation of eligible respondents and their degree of contactabllity. The reported study is concerned with the way the industry attempts to manage contactabiIity. A study of fieldwork managers responSible for over 75% of all phone interviews in Australia revealed a limited use of contact enhancing strategies such as longer fieldwork periods and more callbacks. Commercial imperatives for timely surveys and a lack of end-user concern for response rate issues, along with cost issues, were believed to be responsible.

The paper responds to the release of both the AusCERT and CSI/FBI computer crime and security surveys with a comparison of the results between the two countries' respondents. Overall both surveys show the trend that most organisations employ security technologies but half of them still experience incidents which compromise their security. These incidents have significant quantifiable losses but despite these organisations are still loathed to report to law enforcement agencies for various reasons. These include the impression that law enforcement agencies are not interested, and the negative publicity such incidents can cause in their aftermath.

Survey response rates and response quality are declining in most markets, threatening the viability of many established research techniques. One attempt to combat this has been to make survey completion more convenient for respondents, with on-line surveys being an example of this. This paper looks at respondent attitudes to demographic questions in on-line surveys – questions that are crucial for many analysis practices and yet often have the highest non-completion rates. The exploratory survey conducted here (n=198) examined attitudes towards surveys and empirically examined the reasons behind non-completion and intentions to give misleading information. The results suggest that general attitudes towards providing demographic data in on-line surveys are related to the likely response behaviour, and the more uncomfortable someone claims to be with providing this data, the more likely they will be to either omit a response or exit the survey altogether. Past experience with on-line surveys increases the chances of respondents answering completely and accurately and in most cases, significantly reduces the likelihood of exiting the survey completely if asked these questions. Finally, there is some evidence that providing broad categorical response options is preferred to more specific categories or open text boxes, and this may represent the best technique for improving response rates and quality.

Telephone interviewing is the major data collection method for the market research industry. Although social trends such as mobile phones and call screening make it harder to contact people, better technology and contact regimes can assist companies to ameliorate the situation. A study of fieldwork managers responsible for over 75% of all phone interviews in Australia revealed limited use of contact enhancing strategies such as longer survey periods and more callbacks. Commercial imperatives for timely surveys and a lack of end-user concern for response rate issues, along with costs concerns, were believed to be responsible.

Sampling is fundamental to the credibility of any empirical investigation, and this is no different for the area of Gay, Lesbian and Bisexual (GLB) research. In fact, it would not be an overstatement to say that publication of GLB research into high quality and mainstream journals has been limited in part because of sampling issues. The purpose of this paper is to raise awareness of the unique sampling problems posed by GLB resaerch and to offer solutions to these through the use of web surveys and recruitment strategies. In particular, we provide data which show that, contrary to voiced concerns, when employed with a rigorous recruitment strategy, web surveys increase rather than reduce sampling coverage. Further, we provide evidence that the web survey technique can yield data of comparable quality to that obtained with a hard-copy survey. The paper concludes with strategies researchers can adopt to overcome barriers in obtaining a diverse GLB sample.

Leadership, professional and other transferable skills are embedded in the expected attributes of Australian research postgraduates at the successful completion of their degrees. This paper reports on the development of an evaluation process for a postgraduate transferable skills program at The University of Melbourne, Australia. Existing and emerging evaluation practices and processes are examined in light of the literature on what constitutes 'good' evaluation of the type of program under consideration. The development of the process to go beyond the commonly used participant satisfaction surveys and to improve evaluation practices is described in detail. The results of the evaluation to date are provided and discussed in terms of their usefulness in incorporating particular improvements to the program. The implications for the evaluation of other programs of this type are considered.

Information security is portrayed as a global problem that impacts all countries that are considered as part of the Information Society. Recent surveys show that there are increased concerns about computer crime. The paper will focus upon recent national security surveys from Australia and New Zealand and the trends that this research shows. Is it fair to assume the security practices are the same all over the world? The paper looks at security practices from a number of different countries perspectives and shows that security practices are not generic and vary from country to country. The paper will also evaluate the worth that National Security Surveys have in the field of Information Security Surveys.

Cardiovascular disease (CVD) is the leading cause of death and hospitalization in both men and women in nearly all countries of Europe. The most frequent forms of CVD are those of an atherosclerotic origin, mainly ischaemic heart disease, stroke and heart failure. The magnitude of the problem contrasts with the usual paucity and poor quality of data available on incidence and prevalence of CVD, except for few rigorous but limited studies.
The objectives of the health interview and health examination surveys (HIS/HES) are to evaluate the frequency and the distribution of the disease, to evaluate trends and treatment effectiveness, to estimate risk factors distribution and prevalence of high risk conditions and to monitor prevention programmes.
According to the EUROCISS project (EUROpean Cardiovascular Surveillance Set) recommendations, surveys are aimed at describing the prevalence of the following CVD conditions: myocardial infarction, heart failure, angina pectoris, peripheral arterial disease, stroke, and ischaemic heart disease.
HIS and HES were developed to supplement information collected from routine databases and population-based registers to implement consistent public health policies. HIS can be repeated periodically in a new sample of the population, or can follow up over time the population recruited at baseline. Procedures and methods to collect information from participants include self-administered questionnaires, direct interviewer-administered questions and telephone interviews. A minimum set of questions to be administered every year, along with a longer, more detailed module to be administered periodically are recommended to evaluate CVD prevalence. The addition of HES provides more detailed and objective information that can be used to improve estimates regarding prevalence of both risk factors and disease status.
The selection of more specialized CVD-specific tests will depend on the objective the survey is designed to achieve, the assumed response rate and the cost and time considerations. For HES on CVD the minimum required is to perform the following measurements: height, weight, blood pressure, waist circumference, total and high density lipoprotein-cholesterol and glucose assay in a nonfasting blood sample. The next appropriate step would be to perform an electrocardiogram. High costs usually make HES difficult to carry out.
Standardization of measurements, training of personnel and quality control are essential to assure reliable data. A high response rate is extremely important, as nonrespondents tend to have different health characteristics from the rest of the sample and their omission therefore results in bias.
This manual of operations is intended for health professionals and policy makers and provides a standardized and simple model for the implementation of a CVD survey.
