正现代人因为过度使用电子产品,近视人群越来越多,所以无论是框架眼镜还是隐形眼镜都很畅销。但畅销不代表能完全满足人们的视觉需求,比如近视的人看不清远处,远视的人看不清近处,这种情况会加速眼睛的疲劳度。那么,有没有一款黑科技眼镜让远视近视自动 相似文献

Efforts to estimate various sociodemographic variables in small geographic areas are proving difficult with the replacement of the Census long-form with the American Community Survey (ACS). Researchers interested in subnational demographic processes have previously relied on Census 2000 long-form data products in order to answer research questions. ACS data products promise to begin providing up-to-date profiles of the nation’s population and economy; however, unit- and item-level nonresponse in the ACS have left researchers with gaps in subnational coverage resulting in unstable and unreliable estimates for basic demographic measures. Borrowing information from neighboring areas and across time with a spatiotemporal smoothing process based on Bayesian statistical methods, it is possible to generate more stable and accurate estimates of rates for geographic areas not represented in the ACS. This research evaluates this spatiotemporal smoothing process in its ability to derive estimates of poverty rates at the county level for the contiguous United States. These estimates are then compared to more traditional estimates produced by the US Census Bureau, and comparisons between the two methods of estimation are carried out to evaluate the practical application of this smoothing method. Our findings suggest that by using available data from the ACS only, we are able to recreate temporal and spatial patterns of poverty in US counties even in years where data are sparse. Results show that the Bayesian methodology strongly agrees with the estimates produced by the SAIPE program, even in years with little data. This methodology can be expanded to other demographic and socioeconomic data with ease. 相似文献

In recent years, the discipline of sociology has seen an increased discussion of public sociology, but the discussion has focused on whether or not it is a good idea for sociologists to become more engaged with their various publics. A different question motivates this research: What are the institutional arrangements that make doing public sociology difficult, and thus less likely? Following Dorothy Smith, we start from the perspective of frontline actors and ask them about their experiences. We combine data from two sources: individual interviews with a sample of 50 academic feminists, a group that has theoretical motivation to be interested in public sociology and group interviews with 15 feminists engaged in some form of public sociology. These informants tell us about two related institutional barriers to doing public sociology: the culture of professional sociology and the standards we use for evaluating scholarship. The impact of these disciplinary barriers probably varies by institution type and career stage but there is reason to suspect they generate costs not just for individuals but for the discipline. Taking steps to break down these barriers would ameliorate concerns some have raised about public sociology. 相似文献

Feminist Standpoint Theory identifies knowledge as a social product developed from a specific social position. We apply this theory to explore the dominant standpoint informing the social organization of Western art via an institution we call art/criticism. We find that the assumptions, values, and analytic strategies informing mainstream art and art criticism express the standpoint of privileged men. As a test of our argument, we consider the case of an artist who is often hailed as a feminist artist and yet is one of the most successful woman artists today: Cindy Sherman. We find that while Sherman is working with some fertile possibilities for feminist analysis, her work ends up re‐directing this potential into a disempowering play with images. We conclude that rather than countering our argument, the celebration of Sherman’s work as feminist reveals the workings, as well as the limits, of the privileged male standpoint in art. 相似文献

The Community Education Service (CES) of The Society of Rehabilitation and Crime Prevention (SRACP) has pioneered the adoption of life education in crime prevention education in Hong Kong since 1977. Under this programme, former offenders and drug abusers are recruited to share their experiences with community audiences. Through such sharing, it is hoped that the former offenders and drug abusers will gain a deeper insight into the consequences of committing crime or abusing drugs, have the courage to admit their failings and find the way to lead a more fulfilling and law-abiding life.In the past, different organizations have employed former offenders and drug abusers in educational programmes, particularly in relation to the prevention of juvenile delinquency. A number of studies demonstrate the educational effectiveness of sharing past deviant behaviours with audiences. Moreover, the mission of SRACP is to help the reintegration into society of former offenders and drug abusers. Consequently, employing former offenders and drug abusers to share their experiences serves another important function; to facilitate the transformation of their past histories into valuable assets and help with their own rehabilitation during the process of serving others, as suggested by ‘helper therapy’ and ‘professional ex-s’ (Brown 1991). A successful rehabilitation means success in reducing recidivism.This paper examines whether sharing one's real-life experiences with others can influence the rehabilitation process, and provides recommendations for improving service delivery to benefit both audience and the speakers themselves. Fifteen individuals who were formerly either offenders or drug abusers, aged between 18 and 45 years, and who had led a ‘clean’ life for the previous six months, took part in in-depth interviews in order to investigate their perceptions of the function of real-life experience sharing in their own rehabilitation. Concepts of labelling theory (Becker 1963) and self-fulfilling prophecy (Wilkins 1976) provided the framework for these interviews.The study concludes that respondents are normally able to help themselves to resist crime and drugs, given that the internal and external factors affecting sharing are well addressed. The results identify practical implications and directions for future involvement of former offenders and drug abusers in community-based crime prevention education programmes. 相似文献

Ten years on, the photographs from the US-operated Iraqi prison Abu Ghraib have become synonymous with the war on terror for highlighting an unseemly combat culture. This article focuses on the ongoing functions of these viral photos as objects of cultural memory and also highlights their use as war trophies. Drawing on theories of digital photography, emotional and gestural communication, visual semiotics, and cultural memory, this article examines six of the circulated images. Focusing on the symbolic, the visual contents of the photos are contrasted with the rhetorical account from criminal investigator Brent Pack in the documentary Standard Operating Procedure. While Pack concludes that these images are in fact abusive, he nevertheless dismisses the relevancy of the emoting individuals within the photographs. The arguments here take a particular shape: the pictorial display of emotion is not only relevant, but is essential to the communication of group identity and the perpetuation of cultural memory, which is reinforced by the role that digital photographic technology plays in aiding the circulation of this cultural memory. 相似文献

Quality and quantity: Reconstructing feminist methodology 总被引:1,自引:1,他引:0
Many feminist sociologists have rejected quantitative in favor of qualitative methods, a position which might seem justified
by feminist critiques of positivism. This paper examines both quantitative and qualitative methods in light of two major themes
in radical feminist epistemology, the critique of objectivity and the politics of the research process, and finds both classes
of methods vulnerable. We argue that underlying the argument against quantitative methods is a rejection of abstraction and
a dichotomization of methodologies, both of which are inconsistent with feminist insights. We call for a reconstruction of
methodology that transforms both quantitative and qualitative techniques in ways informed by feminist epistemology and builds
research agendas that integrate both approaches.
Her main research interests are in the development of social measures of gender and in the study of the impact of gender and
class on consciousness.
Her research concerns medical knowledge, social organization, and the health and well-being of women. 相似文献
