Children's Interaction With Commercials*

Public policy attention to numerous issues arising from children's television commercials has resulted in considerable research interest in this area. Most studies have been based on 1) cognitive developmental approaches; 2) survey methods based on parental reports of child viewing; 3) a view of the child as an atomized entity in the viewing environment. This study focuses on interactive episodes of child viewing. Behavior specimens of interactive viewing collected by naturalistic methods are presented illustrating children and parents actively shaping the commercial viewing situation.     

Acts of Last Resort: Asylum,Whistleblowing and the Anthropology of Secrecy

Anthropologists face fresh challenges as they endeavour to conduct research in an increasingly securitised and secretive world. Those who wield asymmetrical power in society often seek to guard information and knowledge. Therefore, it is imperative that anthropologists seek new ways of navigating the politics of secrecy if they are to reveal anything of its inner workings. In pursuit of this imperative, this paper examines practices of whistleblowing and posits secrecy as a dialectic that is characterised by processes and practices that work towards concealment, as well as revelation. In shifting the analytical focus from that which is concealed to what is revealed in acts such as whistleblowing, we contend that anthropologists may elucidate something about secrecy that is revealing of context-specific forms of agency and power. In doing so, analysis draws upon Australia’s secretive immigration and border protection regime and in particular a recent government inquiry that enabled whistleblowers to reveal details of secrets that had previously been closely held.     

Role of bisphosphonates in the management of postmenopausal osteoporosis: an update on recent safety anxieties

Following their introduction in the 1990s, bisphosphonates have become the mainstay of treatment in the management of postmenopausal osteoporosis, and their use continues to rise. Commonly noted adverse effects in clinical practice include gastrointestinal side-effects, acute phase reactions (predominately seen with intravenous preparations) cutaneous reactions and more rarely, ocular side-effects. However, recent reports of potentially serious adverse effects of bisphosphonate therapy, including atypical subtrochanteric and femoral shaft fractures, atrial fibrillation, oesophageal carcinoma and osteonecrosis of the jaw, have prompted concerns regarding the long-term safety of this class of drugs. This review summarizes the benefits and potential adverse effects of bisphosphonates used in the treatment of postmenopausal osteoporosis. Although evidence of a definitive casual relationship between bisphosphonate therapy and serious adverse effects is lacking, concern remains particularly in relation to atypical subtrochanteric and femoral shaft fractures. This has important consequences in terms of determining optimum duration of therapy and how best to target therapy at those most at risk. Recently, attention has focused on individual fracture risk assessment in order to optimize the risk-benefit ratio of treatment for individual patients. A review of the role of hormone replacement therapy in younger women with significant risk of osteoporotic fractures may be timely in these circumstances.     

重构现场:新闻报道的空间叙事策略

新闻报道的空间建构是新闻报道有效叙事之重点环节,聚焦于现场的报道,是一种立足于深刻认知新闻现场和现场新闻之内在关联的选择性重构,现场既代表新闻报道的语境与情境还原,同时也是实现传受双方互动理解的一种审美超越。现场的报道空间建构不仅体现出新闻报道的时效要求对叙事策略选择的必然,更通过叙事设计的结构化、进入化策略来实践传受双方知觉场的共建,尤其在当代新媒体环境下,新闻报道的空间叙事策略将伴随社会空间的心灵感知而不断创新发展。重视并有效发掘、应用那些能够激发受众感知的想象力的空间要素,才是新闻报道未来创新的方向,空间的重构也绝非是媒介技术提供的拟态逼真,而是构建合乎受众认知需求与审美体验的空间实践,是叙事的社会参与,也是其心灵对话空间的共建。     

Immigrant Settlement Patterns: The Role of Metropolitan Characteristics*

Immigration continues to change the social, economic, and political landscapes of urban America. Consequently, scholars, as well as the general public, are interested in the internal migration patterns of immigrants. In this research, we identify and explain the characteristics of metropolitan areas that have the strongest effects on the percentage change in the foreign‐born population between 1990 and 2000. Using lagged independent variables and a sample of 150 metropolitan areas, we find that settlement patterns among immigrants are diverging from traditional patterns. That is, those metropolitan areas that had moderately high levels of globalization and lower costs of living as well as lower disadvantage indicators (e.g., percentage poverty) in 1990, had larger increases in percentage foreign‐born between 1990 and 2000 compared to areas with lower levels of globalization and higher costs of living and disadvantage. These trends suggest the increasing importance of second‐tier metropolises such as Atlanta, Phoenix, and Las Vegas in understanding where immigrants settle.     

Transformations of Old Colony Mennonites: the making of a trans‐statal community

Through an analysis that combines the historical development of the Old Colony Mennonites, which covers their migrations from sixteenth‐century Europe to late twentieth‐century Latin America, with ethnographic field work in Bolivia and Argentina, I examine the genesis and maintenance of a religiously based trans‐statal community. I argue for the conceptual maintenance of a clear distinction between transnational and trans‐statal processes in understanding the cross‐border practices of Old Colony Mennonites. Mennonites do not move in and out of nations but between the territories over which different states claim sovereignty. I further show that the trans‐statal practices of Old Colony Mennonites are a strategic means of outmanoeuvring states in their imposition of national identities within a context of nation‐states being the dominant political formation. The case contributes to the call for a shift in emphasis from nations to faith communities in transnational and trans‐statal studies.     

Some alternatives to Edgeworth

The Edgeworth expansion is well known as a means for obtaining approximate tail probabilities from information concerning the moments of the distribution. Recent saddlepoint and asymptotic methods lead to several alternative approximations. These alternatives are developed and compared by means of average relative error.     

Engaging families of court-mandated youths in an alternative to institutional placement

In a family-centered diagnostic assessment program for youths adjudicated as P.I.N.S. or J.D., placement in short-term foster homes was combined with outreach efforts to engage families in family counseling. Results demonstrated positive feedback by parents and a sharp reduction in the percentage of youths needing institutional placements.     

Approximations to noncentral distributions

Two methods for approximating the distribution of a noncentral random variable by a central distribution in the same family are presented. The first consists of relating a stochastic expansion of a random variable to a corresponding asymptotic expansion for its distribution function. The second approximates the cumulant generating function and is used to provide central χ² and gamma approximations to the noncentral χ² and gamma distributions.
