Managing the risks to which children are exposed in contemporary Britain is complex, requiring parents to balance opportunities for a child’s development with an appropriate concern for the potential consequences. Managing risk is particularly an issue for mothers, who, despite societal changes, tend to retain overall responsibility for the care of children. This paper explores the meanings mothers attach to risk and how this influences their children’s outdoor play. It also extends the scope of much existing literature by including children’s own perspectives on risk in outdoor play. Semi-structured interviews were undertaken with 12 mothers who had children aged between 9 and 11 years old who attended a north-east school. Two focus groups were also held, each with six of the children. Findings are analysed in relation to mother and child constructions of risk; mothers and children as risk managers; and negotiating mothering choices. The paper pays particular attention to the way in which mothers’ decisions were framed within risk cultures and dominant views of ‘good’ and ‘bad’ mothering.  相似文献

This article argues that policy in relation to education has relied too extensively on the more easily measured costs of production to support a common conclusion of economies of scale in school and/or district size. It argues that there are external costs that increase with size but that can be measured less easily that offset this case. This would imply that the tendency within the education profession to advocate ever-larger school sizes is premature at best. To make the case, it models the choice of school size to emphasize that costs, such as school violence, born by both students and their parents but not (necessarily) by education administrators may result in school sizes that are too big from the perspective of school users. The second and third parts of the article introduces evidence to suggest that school violence is one of these external costs.  相似文献

Open space, residential property values, and spatial context   总被引:8,自引:0,他引:8  
We use hedonic analysis of home transaction data from the Minneapolis–St. Paul metropolitan area to estimate the effects of proximity to open space on sales price. We allow the effects of proximity to vary with demographic and location-specific characteristics and include fixed effects to control for observed and unobserved neighborhood characteristics. We find that the value of proximity to open space is higher in neighborhoods that are dense, near the central business district, high-income, high-crime, or home to many children. Using the metropolitan area's average value may substantially overestimate or underestimate the value of open space in particular neighborhoods.  相似文献

Optimal Contracting with Private Knowledge of Wealth and Ability   总被引:1,自引:0,他引:1  
We examine the optimal design of contracts when an agent is privately informed about his wealth, his ability, and his effort supply. We find that the agent's wealth and ability act as perfect complements in determining the power of the incentive scheme under which he operates. Only if his ability and his wealth both increase can an agent be assured of operating under a more powerful scheme. Consequently, severe under-utilization of wealth and ability arise in equilibrium.  相似文献

Trust, reputation and corporate accountability to stakeholders   总被引:6,自引:0,他引:6  
This paper explores the relationship between accountability, trust and corporate reputation building. Increasing numbers of corporations are mobilising themselves to put more and more information out into the public domain as a way of communicating with stakeholders. Corporate social accounting and stakeholder engagement is happening on an unprecedented scale. Rather than welcoming such initiatives, academics have been quick to pick faults with contemporary social auditing and reporting, claiming that in its current form it is not about demonstrating accountability at all, but rather about building corporate reputation. Academics argue that 'accountability should hurt', that if accountability is an enjoyable process, then the organisation isn't doing it right. For organisations that are currently engaging with stakeholders and ostensibly becoming more transparent about their corporate social performance, this kind of critique is likely to be bewildering. This paper argues that central to the notion of accountability and to contemporary social accounting practice is the concept of trust. Accountability is based upon a distrust of corporate management, whereas corporate reputation building is about strategically seeking to establish trust in stakeholder relationships in order to negate formal accountability requirements. Using a split trust continuum, the paper seeks to explain and synthesise what seem to be two very different paradigms of organisational transparency.  相似文献

In many time series models, an infinite number of moments can be used for estimation in a large sample. I supply a technically undemanding proof of a condition for optimal instrumental variables use of such moments in a parametric model. I also illustrate application of the condition in estimation of a linear model with a disturbance that is serially uncorrelated and conditionally heteroskedastic.  相似文献

The importance of Chinese students in Australia has been largely neglected in the tourism development and place branding of Australia. This study explores the factors that influence Chinese students’ word-of-mouth behaviors, as well as other behaviors influencing Australia as a tourism destination. Following a literature review, a taxonomy of word-of-mouth behaviours is proposed in terms of the way information is communicated. “Place attachment to Australia”, “place attachment to China”, and “place satisfaction in Australia”, are proposed as the key factors that influence such behaviors. Using structural equation modelling, the authors find that “place attachment to Australia” and “satisfaction” with Australia are positively related to different behavior outcomes including Chinese students’ word-of-mouth, intentions to recommend Australia as a tourism destination, and willingness to help Chinese tourists to create satisfying experiences in Australia. Based on these findings, the theoretical and practical implications are discussed.  相似文献

Despite the state of flux in media today, television remains the dominant player globally for advertising spending. Since television advertising time is purchased on the basis of projected future ratings, and ad costs have skyrocketed, there is increasingly pressure to forecast television ratings accurately. The forecasting methods that have been used in the past are not generally very reliable, and many have not been validated; also, even more distressingly, none have been tested in today’s multichannel environment. In this study we compare eight different forecasting models, ranging from a naïve empirical method to a state-of-the-art Bayesian model-averaging method. Our data come from a recent time period, namely 2004-2008, in a market with over 70 channels, making the data more typical of today’s viewing environment. The simple models that are commonly used in industry do not forecast as well as any econometric models. Furthermore, time series methods are not applicable, as many programs are broadcast only once. However, we find that a relatively straightforward random effects regression model often performs as well as more sophisticated Bayesian models in out-of-sample forecasting. Finally, we demonstrate that making improvements in ratings forecasts could save the television industry between $250 and $586 million per year.  相似文献
