The health watch case - control study of leukemia and benzene:the story so far

A case–control study nested in the Health Watch cohort of petroleum industry workers, investigated whether the excess of lymphohematopoetic cancers, identified among male members of the Health Watch cohort, was associated with benzene exposure. Cases of non-Hodgkin’s lymphoma (n=31),multiple myeloma (n=15), and leukemia (n=33)were identified between 1981 and 1999. Cases were age-matched to five controls. Exposure was retrospectively estimated for each occupational history using an algorithm in a relational database. Benzene exposure measurements, supplied by Australian petroleum companies, were used to estimate exposure for specific tasks. The tasks carried out within the job, the products handled, and the technology used,were identified from interviews with contemporary colleagues. More than half of the subjects started work after 1965 and had an average exposure period of 20 years. Exposure was low, 85% of the cumulative exposure estimates were<10 ppm years. Matched analyses showed that non-Hodgkin’s lymphoma and multiple myeloma were not associated with benzene exposure. Leukemia risk, however, was significantly increased for the subjects with greater than 16 ppm years cumulative exposure, odds ratio (OR) 51.9 (5.6–477) or with greater than 0.8 ppm intensity of highest exposed job. Cumulative exposures were similar to those found in comparable studies.The inclusion of occasional high exposures, for example, as a result of spillages, reduced the ORs, when the exposure was treated as either a continuous or a categorical variable. Our data demonstrate a strong association between leukemia and modest benzene exposure. The choice of cut-point and reference group has a marked effect on the ORs, but does not change the overall conclusions.

Non-formal education for women workers in Thai industry

This study focuses on non-formal education provision for women workers in industry in Thailand. It consists of a dissertation and four elective studies. The dissertation explored the possibilities to improve women workers' quality of life. The experience gained from the research formed the Participatory Approach Model called "PAM".

Tourism, guest workers, and resident immiserization

This paper analyses the impact of a boom in tourism on the welfare of the residents in the presence of guest workers. Guest workers are employed in the tourism industry and they consume non-traded goods and services. This consumption by guest workers converts non-traded goods into
exportables and creates guest worker generated monopoly power in trade in the home country. It is established that under certain plausible conditions a tourist boom (in the presence of guest workers) results in the immiserization of the resident population. This result arises due to an adverse movement in the terms-of-trade, specifically those associated with the guest workers consumption of non-traded goods. These results are based on a static model of trade and may not be necessarily
valid in a growth model with guest workers, tourism and labor shortages. It is not the object of the paper to be either anti-tourism or anti-guest worker, but only to show a possible source of resident immiserization that is associated with guest workers. This possibility may require correction via a suitable policy both in static and dynamic models.

Prediction intention to quit in the call centre industry: does the retail model fit?

Purpose – Models of workplace turnover are rarely assessed in contexts other than that in which they were developed. This reduces their generalizability and their usefulness in providing managers with guidance as to what they might do to reduce workers intentions to quit. The purpose of this study is to test a model derived from a study of shop floor retail salespeople in the call centre environment.

Design/methodology/approach – A questionnaire measuring the variables in the model was completed by 126 call centre representatives recruited from 11 call centres in Melbourne, Australia.

Findings – Although the model was supported, the interactions among the variables differed. In particular, stressors played a bigger, albeit indirect, role in the intention to quit.

Practical implications – Call centre managers need to consider carefully the aspects of the work environment that may be stressful. If appropriately addressed, turnover may be reduced, and productivity increased.

Originality/value – This paper demonstrates that the model of turnover derived from shop floor salespeople is generally robust in the call centre setting. It provides management of call centres with some guidance as to the factors associated with turnover and areas that can be addressed to reduce it.

Technological change in the postproduction film industry

Technological change in the postproduction film and television industry has affected workers differently depending on age, gender, experience and reputation.

Mothering in the freelance film industry: case studies in the postproduction film industry in Melbourne, Australia

This paper examines the dynamic relationship between work and life through the experiences of three mothers seeking to realise careers in the freelance film industry in Melbourne, Australia. The women were part of a larger sample of postproduction workers who were surveyed on their responses to technological change in the postproduction freeelance film industry but were out of the industry having children during the first wave of technological change. The paper examines qualitative data from these women and later longitudinal data in order to understand the limits of equal opportunity in an uneven playing field.

Technological change in the postproduction film industry a Victorian case study

The first and last stages of filmmaking production and projection remain relatively unchanged, but computerization (through digitalization) has radically transformed film and sound editing. The aim here is to examine some of the effects of this transformation on postproduction employment. The experiences of twenty Victorian postproduction workers, interviewed in 2001, provide the data presented here. The interviewees were divided into groups to reflect their life stage and time working in postproduction.

Review of the quality of studies on the economic effects of smoke-free policies on the hospitality industry

Objective: To compare the quality and funding source of studies concluding a negative economic impact of smoke-free policies in the hospitality industry to studies concluding no such negative impact.

Data sources: Researchers sought all studies produced before 31 August 2002. Articles published in scientific journals were located with Medline, Science Citation Index, Social Sciences Citation Index, Current Contents, PsychInfo, Econlit, and Healthstar. Unpublished studies were located from tobacco company websites and through internet searches.

Study selection: 97 studies that made statements about economic impact were included. 93% of the studies located met the selection criteria as determined by consensus between multiple reviewers.

Data extraction: Findings and characteristics of studies (apart from funding source) were classified independently by two researchers. A third assessor blind to both the objective of the present study and to funding source also classified each study.

Data synthesis: In studies concluding a negative impact, the odds of using a subjective outcome measure was 4.0 times (95% confidence interval (CI) 1.4 to 9.6; p = 0.007) and the odds of not being peer reviewed was 20 times (95% CI 2.6 to 166.7; p = 0.004) that of studies concluding no such negative impact. All of the studies concluding a negative impact were supported by the tobacco industry. 94% of the tobacco industry supported studies concluded a negative economic impact compared to none of the non-industry supported studies.

Conclusion: All of the best designed studies report no impact or a positive impact of smoke-free restaurant and bar laws on sales or employment. Policymakers can act to protect workers and patrons from the toxins in secondhand smoke confident in rejecting industry claims that there will be an adverse economic impact.

Common industry exposure in seemingly unrelated commodities

We propose and document robust evidence of cross-market return, volatility, and volume interactions among futures contracts written seemingly unrelated commodities exposed to a common industry. On the Tokyo Commodity Exchange, we find such evidence in natural rubber (NR), aluminum (AL) and gasoline (GA) futures markets, which are complementary commodities heavily consumed by Japan's automobile industry. Our VAR results indicate that (i) for shorter dynamics, NR and GA volatility both influence AL volatility; GA volume affects NR volatility and volume; the GA market is immune to both NR and AL trading activities; (ii) for longer dynamics, AL volume affects both NR volume and GA volatility; NR volume influences GA volume. These results are robust to lag-specifications, volatility measures and are consistent with full BEKK-GARCH estimates. Further analysis using the silver contract, TOCOM and TOPIX transportation indices, shows that a commodity market factor cannot explain our result. Our results offer insights into how commodity and equity markets relate at an industry level.

Preparing for flexible delivery in industry : learners and their workplaces

This thesis examines the learning preferences and learning strategies of apprentices, and the contexts within which they learn in their workplaces. Since the end of the 1980s Australian vocational education and training (VET) structures and processes have undergone radical change in attempts to develop skills in the workforce that will ensure enterprise, national, and international competitiveness. A major strategy in the national reforms has been the encouragement of flexible delivery as a means through which workplace-based learning can be accessed by a larger number of workers in ways that are cost-efficient, and that reduce the amount of time that workers spend away from their jobs. Although flexible delivery has been championed by governments and industry alike, there has been little attempt to identify the preparedness of either learners or their workplaces for the demands of flexible learning. The thesis examines the economic context for these changes to VET, and also examines the literature available on workplace learning. Additionally, the thesis examines the conceptualisations of flexible delivery that are available in the literature, pointing to the possibility that the wide range of meanings associated with the term ‘flexible delivery’ may result in quite different practices and expectations. The thesis also examines the literature on independent learning and self-directed learning, and explores the concept of ‘client-focused’ flexible delivery. The study of learner preferences uses data collected from apprentices over a period of some years, in the four occupational areas commanding the highest number of apprentices in Australia. These occupational areas are Metals and Machining, Building, Electrical, and Hairdressing. These data on learning preferences are collected using the commercially available Canfield Learning Styles Inventory (CLSI). The data from the sample of 389 apprentices are analysed statistically through analyses of variance, and indicate that variables such as age, gender, and occupational area are related to learning preferences. Apprentices are shown by this analysis to prefer structured programs of instruction that are instructor-led, and to not have a high preference for independent learning or the development of their own learning goals. Additionally, they are shown to have very low preferences for learning through reading, preferring instead to learn through direct hands-on experience. While these characteristics are largely common among the four occupational groups, the Hairdressing apprentices are shown to have a slightly higher preference for independent learning and goal setting. Females are shown to have a higher preference than males for learning qualitative material through reading. Interestingly, the younger apprentices are shown to have a higher preference than the older ones for self-directed learning. Some possibilities for that finding are discussed. The research also shows that the learning preferences displayed by different groups of apprentices in any one program are much the same over time, providing some confidence that data generated from one group of apprentices can be used to make instructional decisions for future groups in the same program. The data are also factor analysed to indicate three major factors underlying apprentice learning preferences. The first factor indicates a Verbal–Non-verbal preference factor, with apprentices clearly preferring to learn through non-verbal means. A second factor is described as Structure–Content, with apprentices showing a preference for learning from structured programs in a structured environment. A third factor, Self-directed–Social preference, indicates apprentices preferring to learn through socially mediated presentations and contexts rather than through more independent forms of learning. Qualitative data are also generated through interviewing eight apprentices, and focusing on the learning strategies they employ while constructing knowledge in the workplace. That component of the research uses a modification of the Marland, Patching and Putt (1992a, 1992b) stimulated recall technique, and a set of learning strategies derived from the work of O’Malley and Chamot (1990) and Billett (1996a). The eight apprentices are drawn from the Metals and Machining, Electrical, and Hairdressing trades. The findings indicate that the learning strategies most often used by apprentices in the workplace are those associated with the construction of knowledge that is structured and provided by the instructor or learning program, and those that include social mediation of learning. Additionally, the strategies associated with demonstration and hands-on practice are most favoured. The qualitative data are confirmatory of the quantitative data. The research also indicates, through the apprentice interviews, that support for apprentice’s learning in their workplace is typically unplanned and haphazard. Their experience was sometimes characterised by a reluctance on the part of the workplace to acknowledge learning needs such as trialling and practice of new knowledge, or pro-actively seeking understanding from other more skilled workers. The learning preferences and learning strategies findings for apprentices, coupled with the findings of typically poor or unplanned support in the workplace, indicate that effective flexible delivery of training to apprentices in the workplace provides a number of challenges. These challenges, it is argued, demand strategies to be developed and implemented to prepare both learners and workplaces for effective engagement with flexible delivery. Using as a theoretical framework Kember’s (1995) two-dimensional model of open learning for adults, the thesis integrates the findings into a proposed two-dimensional model of learner and workplace preparedness for flexible delivery. The model provides for a Learner Development Space, a Workplace Development Space, and a Strategy Space. Within the Learner Development Space, focuses for the development of learner preparedness are identified in terms of self-directed learning, skills developments, and effective participation in a community of practice. Focuses for workplace development identified in the Workplace Development Space are those associated with development of training policies, training structures, and trainer skills and abilities. The Strategy Space then provides detail of seventy-nine specific strategies developed to enhance learner and workplace preparedness within each of the focuses identified.

Implementing a suitable jobs register in the construction industry : preliminary evidence

This pilot study investigated the efficacy of a job register index to support return to work (RTW) for injured workers in the construction industry. Participants included injured workers (n = 22), supervisors/managers (n = 23), treating practitioners (n = 5), occupational rehabilitation consultants (n = 5), union representatives/occupational health and safety representatives (n = 5), RTW coordinators (n = 2), steering committee members (n = 4) and the designated project officer (n = 1). A pre–post test intact group design was used to evaluate the perceived utility of the job register. A partial set of the sample including injured workers and supervisors/managers participated in the pretrial phase (n = 28) while the trial phase included more numerous stakeholder groups to assess the perceived utility of the register (n = 39). Participants completed surveys that incorporated a number of differing sections including injury description and circumstances, communication and collaboration with others, their overall opinion of the return to work process in general and suggestions for future improvements. Additional questions were designed for those participating in the trial with regards to the efficacy of the register. Data were analysed using analysis of variance procedures with pairwise comparisons of pre–post intervention test means. Alternative job options were seen to be offered more frequently. Communication and cooperation improved post implementation. Supervisors perceived the job register a useful innovation to facilitate RTW. The register represents a new resource to the construction industry with potential for wider application following further study.

Physical activity initiatives for male factory workers : gatekeepers' perceptions of potential motivators and barriers

Objective: Worksites have been argued to be a key setting for physical activity promotion, particularly for lower-paid, less-skilled workers. These occupational groups are at increased risk of cardiovascular disease. There is no strong evidence in support of the efficacy of worksite fitness and physical activity interventions. This study assessed potential motivators and barriers to worksite physical activity initiatives for less-skilled workers.

Method: We conducted telephone interviews with 13 Victorian WorkCover insurance providers and 30 manufacturing industry worksite managers. The manufacturing industry was selected as it contains a substantial portion of workers from this high-risk occupational group.

Results: Most insurers incorporated physical activity elements into injury-prevention programs. Few worksite managers reported programs to encourage workers to be more active; they identified reduced premiums and lower-cost programs through insurers as possible motivators. Both groups identified workers' reluctance to participate in physical activity, lack of awareness of potential benefits and program cost as major barriers for worksite physical activity. Other barriers included potential adverse effects on productivity and increased injury risk.

Conclusions: Broader occupational health and safety policies and joint initiatives between insurers and worksite managers may have the potential to provide more opportunities for workers to be more active. However, the barriers identified outweighed the perceived benefits.

Implications: Without structural and regulatory changes or new incentives, the adoption of physical activity initiatives in Australian manufacturing-industry workplaces is unlikely.

Physical activity promotion for male factory workers : a realistic option?

Issue addressed: Worksites are a promising setting for health promotion initiatives. While there is an accumulated body of evidence indicating favourable health and cost outcomes, there have been difficulties identified in recruiting and influencing blue- collar workers. This descriptive study aimed to identify specific opportunities and barriers which may impact upon physical activity options at work for male blue-collar factory workers.

Methods: Fifteen manager interviews and worksite observations, and eight employee group discussions were conducted in manufacturing industry worksites.

Results: Several key barriers emerged which limit opportunities for blue-collar employees to participate in physical activity at work: time constraints; limited facilities; and lack of interest from management to facilitate physical activity due to limited resources and concerns about safety issues. Potential opportunities included the presence of change rooms, showers, outdoor areas suitable for physical activity, nearby parks and local fitness facilities, and occupational health and safety committees.

Conclusions: Increasing opportunities for workers to be active at work did not emerge as a priority of managers who may need to be convinced that allocating time and resources to physical activity is a wise investment and that workers need an environment that both supports and encourages participation in physical activity. The role of physical activity in relation to injury prevention and potential reductions in Workcover premiums is worthy of further investigation.

So what? While worksite physical activity promotion is a national health objective, there are numerous actual and perceived barriers to initiatives directed at factory workers. Rather than offering specific programs, it may be more productive to address work practices and environmental and regulatory barriers through established occupational health and safety channels. Information and education strategies to change the attitudes and beliefs of management and workers about these issues, as well as about the health benefits of physical activity, may also be helpful.

Construction pathway : attracting the missing students and workers to university

The Commonwealth Government has the increased participation of under-represented groups to a 20% diversity target for Australian universities. It also has minimum targets of 40% of all Australians (25-34 years) holding a Bachelor’s degree by 2020. These targets are baseline items in a government agenda of improving educational outcomes for Australians and pivotal in addressing skill shortages in industries such as construction. In construction there is a skewing of skill shortages to the higher order or post entry level skills. Demand for higher skilled occupations such as construction managers, outstrips demand for construction trades (DEEWR, 2010). But whilst 41% of the industry have VET qualifications, only 10% possess HE qualifications in construction. Movement between the VET and HE sectors is low: of all construction students qualifying at AQF 4, less than 10% continue on to higher education and less than 1% of VET qualified persons in the construction workforce seek re-entry to university. This paper examines national data in construction education pathways and evaluates, using the DEMO matrix, the enablers in pathways to HE qualifications. The evaluation is based upon survey responses of two cohorts entering higher education from non-traditional pathways- articulating VET students and mature-aged workers. The results indicate that pathway programmes into construction degrees can attract non-traditional cohorts, but elements such as learner engagement, confidence, people-rich resources and collaboration are critical features of successful pathways.
