This study of the developing Welsh Assembly (WA) provides a unique opportunity to comprehend how the values and public statements of a democratic institution's initial and ongoing leadership develop its structure and culture. We track the evolution of a new democratic institution and investigate relationships between leadership, path-dependency and cultural development. In this paper, Welsh Assembly Member (AM) leadership is analysed in relation to sources of path-dependency in the WA. Two sets of interviews and surveys provide AM perspectives of the Assembly in relation to the evolving leadership capability and institutional culture.  相似文献

This study explores full‐time workers' understanding of and assumptions about part‐time work against six job quality components identified in recent literature. Forty interviews were conducted with employees in a public sector agency in Australia, a study context where part‐time work is ostensibly ‘good quality’ and is typically long term, voluntary, involving secure contracts (i.e. permanent rather than casual) and having predictable hours distributed evenly over the week and year. Despite strong collective bargaining arrangements as well as substantial legal and industrial obligations, the findings revealed some serious concerns for part‐time job quality. These concerns included reduced responsibilities and lesser access to high status roles and projects, a lack of access to promotion opportunities, increased work intensity and poor workplace support. The highly gendered, part‐time labour market also means that it is women who disproportionately experience this disadvantage. To foster equity, greater attention needs to focus on monitoring and enhancing job quality, regardless of hours worked.  相似文献

Presentation format can influence the way target audiences understand risk-related information. Brochures or fish fact sheets are the methods traditionally used by state agencies to inform the public about fish consumption advisories and the risks from consuming fish. This study examines the efficacy of presenting information about the risks from consuming contaminated fish and shellfish in two different formats: a brochure and classroom presentation. The two instruments were developed and tested in Spanish and English, reflecting the local ethnic composition in the Newark Bay Complex. The instruments were tested on women of child-bearing age at the Women, Infants, and Children Center in Elizabeth, New Jersey. Detailed diagrams were used in both presentations, including contaminated fish species, fish preparation methods, and food chain bioaccumulation and transmission to the fetus. There were few language-related differences in the efficacy of the classroom lesson, and the main ideas were understood by both groups. Where there were significant differences in understanding about the risks from consuming fish or crabs from the contaminated waters of Newark Bay, in all cases the women exposed to the classroom lesson had a better understanding than those who read the brochure. Ninety-six percent of the women who heard the lesson understood that it was unsafe to eat fish from the port, compared to 72% of those reading the brochure. Both formats succeeded in imparting information to most women about the area under advisories, the fish species under advisories, and transmission of toxins to the fetus. Information on fish preparation was recalled less clearly, partly because women were asked to relate methods to reduce the risk from consuming fish from 11 presented, and most recalled only two or three of the list. The advantages and disadvantages of conducting short classes to women of child-bearing age are discussed.  相似文献

Numerous responsible gambling (RG) strategies are promoted to assist consumers to “gamble responsibly”. However, consumer adoption of RG strategies, how this varies by gambler risk group, and whether usage is associated with non-problematic gambling are largely unknown. This study aimed to (1) determine how use of RG-related strategies differs amongst regular gamblers by gambler risk group; and (2) identify RG-related strategies whose usage predicts non-problem/low risk gambling. Regular Australian gamblers on high-risk products (N = 860), recruited through gambling venues and an online wagering operator, were surveyed about their use of RG strategies promoted on the website of their jurisdiction’s main RG agency. Knowledge of RG strategies was reasonably high amongst all gambler risk groups, but lower-risk groups were more likely to use RG strategies. A logistic regression correctly predicted 82.1 % of lower-risk gamblers and 77.2 % of higher-risk gamblers. Predictors of lower-risk gambling included: greater confidence in their understanding of RG; endorsement of lower gambling expenditure and frequency limits; fewer erroneous gambling beliefs; being less likely to gamble to win money, challenge their skills/beat the odds, or forget about worries and stresses; and being more likely to gamble for pleasure/entertainment. Lower-risk gamblers were more likely to set a money limit in advance of gambling and to balance their gambling with other activities. These findings contribute to understanding which strategies are favoured by different risk groups, and which are associated with safer levels of gambling. They can guide consumer information aimed at enhancing RG consumption and future research on RG consumption.  相似文献

Background

Increased circulating levels of prolactin have been associated with increased risk of both in situ and invasive breast cancer. We investigated whether or not physical activity had a dose–response effect in lowering plasma levels of prolactin in postmenopausal women.

Methods

Four hundred previously inactive but healthy postmenopausal women aged 50–74 years of age were randomized to 150 or 300 min per week of aerobic physical activity in a year-long intervention. Prolactin was measured from fasting samples with a custom-plex multiplex assay.

Results

A high compared to moderate volume of physical activity did not reduce plasma prolactin levels in intention-to-treat (Treatment Effect Ratio (TER) 1.00, 95% Confidence Interval (CI) 0.95 – 1.06) or per-protocol analyses (TER 1.02, 95% CI 0.93 – 1.13).

Conclusions

It is unlikely that changes in prolactin levels mediate the reduced risk of breast cancer development in post-menopausal women associated with increased levels of physical activity.

Science fiction (sf) does more than provide a fleeting moment of entertainment; it has many personal and social functions. In addition to offering audiences “romantic escapism” (Gerrold, 1996, pp. 5–6), sf also enables the “postulation of an alternative reality from which to contemplate this one” (Gerrold, 1996, pp. 5–6); as such, it is especially important “for groups which have had limited stakes in the status quo” (Jenkins, 1995, p. 242). To date, no research has been undertaken on the relationship between Australian queers and sf fandom. This article reports the findings of an online survey and explores the psycho-social features of Australian queer sf fans and why they like the genre. While the characteristics of this sample mirror those of Australian queers generally, they also have slightly higher rates of mental illness and are far more likely to state they have “no religion.” Furthermore, while enjoying the “sciency” (P10, bisexual woman) aspects of sf, Australian queers also like the “poignant metaphors for our own civilization” (P45, asexual man)  相似文献

Whilst there is a wealth of research into family communication and family relationships, there is little information about whether (and if so how) mobile phones have impacted on these processes. The authors’ study involved individual semi‐structured interviews with 60 families, including parents/carers and young people aged 11–17, to investigate this further. The interviews explored how mobile phones are used in family communication; participants’ views about the benefits and disadvantages of mobile phone use; and issues around safety, surveillance and privacy. The findings show that young people and parents see mobiles as a key way for families to keep in touch, and to monitor and ensure young people’s safety. However, some participants felt there was a downside to this, in relation to some young people either withdrawing into their own social worlds, or having a false feeling of security as a result of having a mobile. Gender differences in views and usage were also found. The paper concludes with some general comments about the role of mobile phones in family life.  相似文献

Excluding very severe child abuse cases, biological parents are usually encouraged to maintain contact with their children in care. Parent‐child contact is often considered important because it can maintain the child's psychological identity and well‐being. It can also maintain parent‐child attachment and in some cases facilitate reunification. Improving parenting skills is viewed as an important method by which contact between children and their biological parents can be enhanced. However, mainstream parenting groups are often unsuitable for parents whose children are in care for a number of reasons. There is stigma involved with having children in care, such parents have very complex lives and there are reduced opportunities to practise skills learnt with their children. Groups designed specifically for parents whose children are in care appear to be a promising approach to improving the quality of contact between these parents and their children. This paper will review group‐based approaches to working with biological parents whose pre‐school‐aged children have been placed in care. The paper will also report the findings of a research project designed to identify key facilitators and barriers to parental involvement in a group‐based programme which includes contact between parents and their children who have been placed in care.

This paper examines autonomy, choice, options, and power in healthcare decision making for older people. Using discourse analysis and a case study from data gathered as part of an ethnographic field study we critique a common conceptualization of healthcare decision making as patients choosing from an array of options offered by healthcare providers. A discourse of “giving options and being realistic” used by healthcare providers is contrasted with the experience of a single patient's transitional care from hospital to home after hip fracture. This illustrates how a wide variety of actors, institutions, values, and resources take precedence in determining a discharge destination. While the accounts given by healthcare providers cast patient choice in respectful terms, an ethnographic approach illustrates that the “choices” are structured by a discourse which simplifies the complexity of what is offered and who gets to choose. In the case study the patient's choice was subjugated by expertise and institutional concerns; her options were largely illusory; and her autonomy was “at risk” due to her age, poor health, and limited resources. We use Foucault's ideas about discourse and governmentality to question the scope of agency in healthcare decision making. We argue that the conceptualization of informed patients making autonomous choices acts as “misdirection” which deflects problem solving and discussion away from a productive examination of the differences between healthcare system offerings and client needs. We conclude by posing questions to reorient the debate surrounding healthcare decision making for older adults and recommend a more participatory approach to designing social services.  相似文献

This paper reports an experimental test of the Porter Hypothesis that environmental regulations create innovation offsets that would not otherwise be undertaken. Using a process analysis framework to consistently account for non-separabilities in production and pollution abatement practices, the findings suggest productivity gains can appear to be greater with environmental regulations than without even though they are not. This result which would seem to support the Porter argument, is the result of inadequacies in the methods used to decompose the influences to productivity change. Thus, the experiments offer one explanation for why it has been difficult in practice to reject the hypothesis.  相似文献
