This article offers an ethnographic account of the significance of rap music and hip hop culture for white youth in the city of Newcastle upon Tyne in north-east England. Although white appropriations of black music in Britain have been well documented in sociological work, there is currently very little research on white responses to rap and hip hop. During the course of this article I identify two distinct responses on the part of white Newcastle youth to rap and hip hop. I then go on to argue that, despite their differing nature, each of these responses can be seen as bound up with issues of locality and local experience.  相似文献

Nobody could accuse the Royal Statistical Society's President Andy Grieve of looking for a quiet life. As well as being a consultant statistician for pharmaceuticals company Pfizer, he has for many years been heavily involved with the Society and Statisticians in the Pharmaceutical Industry. However, he claims to Helen Joyce that his early career was shaped by a fondness for "taking the easy option".  相似文献

For the evaluator who is part of the management of a human service organization, future expectations will be more demanding than at present. Operating staff, managers, and funders will already be familiar with the methods and the usefulness of capable program evaluation. Improved information tools will help the evaluator meet this challenge, by keeping the organization visible and manageable. A more fundamental change will be an improved “language of accountability”. Program standards, accreditation, and review now focus on structure and process characteristics. What is emerging is a growing consensus on definitions of client problems and program objectives in relation to these problems. This consensus spurs psychometric research on measures of problems and of the attainment of program objectives. Dependable, standard measures and meaningful comparative data will make the evaluation of program effectiveness possible.  相似文献

Although rare in the west, in Japan and in some other advanced countries on the Asian‐Pacific rim, there is a popular perception that there has been a significant increase in the numbers of young people who withdraw socially for protracted periods of time (referred to by the Japanese term ‘hikikomori’). This paper describes the hikikomori phenomenon in Japan, considers evidence relating to its prevalence and examines views about the causes. I argue that the tendency to think of hikikomori as a homogeneous group characterised by psychological malaise is misleading and that withdrawal and disengagement can also be linked to changing opportunity structures. The collapse of the primary labour market for young people and the growing prevalence of a precarious secondary sector has led to a situation in which traditional and deep‐rooted norms are undermined and young people forced to find new ways of navigating transitions within a highly pressured and rigid system. Under these circumstances, acute withdrawal often represents an anomic response to a situation where tradition no longer provides adequate clues to appropriate behaviour rather than as a malaise reducible to individual psychologies.  相似文献

We consider simulation-based methods for exploration and maximization of expected utility in sequential decision problems. We consider problems which require backward induction with analytically intractable expected utility integrals at each stage. We propose to use forward simulation to approximate the integral expressions, and a reduction of the allowable action space to avoid problems related to an increasing number of possible trajectories in the backward induction. The artificially reduced action space allows strategies to depend on the full history of earlier observations and decisions only indirectly through a low dimensional summary statistic. The proposed rule provides a finite-dimensional approximation to the unrestricted infinite-dimensional optimal decision rule. We illustrate the proposed approach with an application to an optimal stopping problem in a clinical trial.  相似文献

The portmanteau statistic is commonly used for testing goodness-of-fit of time series models. However, this lack of fit test may depend on one or several atypical observations in the series. We investigate the sensitivity of the portmanteau statistic in the presence of additive outliers. Diagnostics are developed to assess both local and global influence. Three practical examples demonstrate the usefulness of the proposed diagnostics.  相似文献

The idea of 'audience' no longer appears to suit media studies. Conceiving the public as sponges for information and entertainment may have worked in the television age. But not so the computer, mobile phone, iPod era. Increasingly, it appears that the public amuse and inform themselves, using media to create and circulate their own content. This presents media scholars with a considerable challenge, as outlined in David Gauntlett's announcement of 'Media Studies 2.0'. One goal of the new discipline is to dispense with 'audience' as a meaningful category. This essay will argue that this is a rhetorical shift only possible because of audience research. Additionally, in describing a study of young student drinkers, the essay will argue that traditional, 'receiver' definitions of audience offer an important means for the public to enter policy debates on binge culture. Abandoning audience thus also means ignoring media issues that the public feel are important.  相似文献

In this article I argue the need for critical evaluation of qualitative research methodology in sociological studies of the relationship between youth culture and popular music. As the article illustrates, there is currently an absence of critical debate concerning methodological issues in this field of sociological research. In the first part of the article I begin to account for this absence by illustrating how early research on youth and music rejected the need for empirical research, relying instead on theories and concepts drawn from cultural Marxism. The second part of the article illustrates how the legacy of this early body of work in youth and music research manifests itself in current research which, although empirically grounded, is characterized by an almost total lack of engagement with methodological issues such as negotiating access to the field, management of field relations and ethical codes. Similarly problematic is the uncritical acceptance on the part of some researchers of their insider knowledge of particular youth musics and scenes as a means of gathering empirical data. In the final part of the article I focus on the issue of insider knowledge and the need for critical evaluation of its use as a methodological tool in field-based youth and music research.  相似文献

In the present article, we present a theoretical perspective on ageism that is derived from terror management theory. According to the theory, human beings manage deeply-rooted fears about their vulnerability to death through symbolic constructions of meaning and corresponding standards of value. We extend this perspective to suggest that elderly individuals present an existential threat for the non-elderly because they remind us all that: (a) death is inescapable, (b) the body is fallible, and (c) the bases by which we may secure self-esteem (and manage death anxiety) are transitory. We review some recent empirical evidence in support of these ideas and then discuss possible avenues for combating ageism.  相似文献

There have been many studies of mercury geochemistry in the environment and its bioconcentration/bioaccumulation through the aquatic food chain. However, there is a dearth of information regarding the bioaccessibility of mercury in human receptors exposed primarily by soil ingestion. This paper reviews the current state of knowledge of mercury bioaccessibility and speciation in soils, and the utility of speciation methods to estimate mercury bioaccessibility. We conclude that additional research is necessary to determine: (1) whether analytical measurements can adequately determine the bioaccessibility of mercury in sediments and soils; (2) the accuracy of in vitro analyses in assessing mercury bioaccessibility; (3) the ability of mercury to cross tissue membranes of the mouth, esophagus, stomach, and the small and large intestines; (4) the speciation and distribution of mercury in biological fluids; and (5) mercury bioavailability using an in vivo animal model relevant to human gastrointestinal tract conditions.  相似文献
