The certification test for English teachers in a certain state asked candidates to identify the name of the frog in Mark Twain's "The Celebrated Jumping Frog of Calaveras County." If students answered this question correctly and said, Dan'l Webster, does this mean that these students would be prepared for the teaching field? Conversely, if students answered this question incorrectly, does this mean they were ill - prepared for becoming teachers? Can such an irrelevant question really point to the knowledge and abilities of future teachers? Hardly, use of unimportant questioning such as this illustrates the main problem with using a multiple choice format when assessing students. Trivial items such as names of animals and other insignificant information are often given priority over their significance in the story simply because students are not able to demonstrate what they really know in narrative form (Smagorinsky, 2002).  相似文献

The current literature on aging and ageism is summarized in support of a theoretical perspective that includes both the biological and the psychosocial components of these processes. Conceptual and methodological problems are identified in models that rely on a deficit approach to aging. We suggest that the biased responses of others foster older adults' stress-related emotional and hormonal responses—responses that may effectively reduce their social and cognitive competence. This negative feedback process ultimately acts in a stereotype-maintaining fashion. Implications are drawn for possible changes in social policy and institutional practices that may reduce or prevent the harmful effects of ageism. Examples are given of existing policies and practices that limit the lives of older adults (in the guise of protection), along with newly instituted policies and practices (including those at an international level) that place the welfare of older adults in the context of life course issues shared by all.  相似文献

ABSTRACT

This article explores the technical limitations of audio recordings and how those limitations impact the reliability of sound evidence in police use of force cases. In audiovisual recordings, audio is often assumed neutral, redundant or to have the same limitations as its visual counterpart. Bringing together film theorist Michel Chion’s concept of audio-vision and the technical specifications of mobile audio recording, this article highlights how design priorities and compression processes can influence the way sound evidence is perceived. By failing to acknowledge audio recordings as distinct from their visual counterparts, they are rendered invisible and are therefore under scrutinized throughout legal processes. This neglect becomes notably problematic in cases of police use of force where audio/visual recordings often work to bolster the already privileged officer testimony.  相似文献

The present study will examine energy consumption from two competing perspectives within environmental social science: political economy and ecological modernization. These frameworks will be evaluated with a fixed‐effects panel analysis of state‐level energy use between the years 1960 and 1990, based on data for 50 states plus Washington, DC, from the Energy Information Administration’s State Energy Data System. The results from the panel analysis show that the increase in total energy use between 1960 and 1990 depended on both increasing economic growth and urbanization, even after controlling for population size, industrialization, and inflation‐adjusted energy prices. The results challenge the claims of ecological modernization theory and support a political economic approach to the study of changes in energy use. In the conclusion, the study’s findings will be framed within the context of the early twenty‐first‐century economic and ecological crises. In light of efforts to reduce greenhouse gas emissions, this study can also further advance the renewable energy debate by reminding us of the social drivers of energy use.  相似文献

Sport participation and positive development in older persons   总被引:2,自引:1,他引:1  
In many Western countries, more and more people are living longer. As part of this demographic shift, increasing numbers are participating in Masters sport. In the past, sport was considered important for the development of young people; however, the potential for sport participation to affect positive development across the lifespan is now recognized. The purpose of this paper is to introduce conceptual frameworks from developmental psychology that are being used to understand youths’ positive development through sport, and to explore these frameworks in the context of sport as an avenue for positive development in older persons. To achieve this aim, we outline research on sport participation as it applies to youth development and consider relevant aspects as they broadly apply to development later in life. This discussion highlights the inherent paradox of sport participation—that it has the potential to provide considerable positive growth but also the potential for significant negative consequences. Finally, we explore areas of future research related to positive development in older persons through sport.  相似文献

This paper considers Lagrange Multiplier (LM) and Likelihood Ratio (LR) tests for determining the cointegrating rank of a vector autoregressive system. n order to deal with outliers and possible fat-tailedness of the error process, non-Gaussian likelihoods are used to carry out the estimation. The limiting distributions of the tests based on these non-Gaussian pseudo-)likelihoods are derived. These distributions depend on nuisance parameters. An operational procedure is proposed to perform inference. It appears that the tests based on non-Gaussian pseudo-likelihoods are much more powerful than their Gaussian counterparts if the errors are fat-tailed. Moreover, the operational LM-type test has a better overall performance than the LR-type test. Copyright O 1998 by Marcel Dekker, Inc.  相似文献

This paper examines the attitudes of 285 hunters and fishermen from South Carolina about hunting and fishing, risk, environmental issues, and future land use of the Savannah River Site. We test the null hypothesis that there is no difference in hunting and fishing rates, attitudes toward the safety of fish and deer obtained from SRS, attitudes toward future land use at SRS, and perceptions of the severity of environmental problems as a function of how far respondents lived from the site. Respondents hunted or fished an average of over 40 days a year, and only half felt that the fish and deer from SRS were safe to eat. Willingness to expend federal funds was correlated with perceptions of the severity of the problem. Preferences for future land use at SRS fell into three categories: high (environmental research park, hunting, fishing, camping), medium (nuclear production, factories, preserve only), and low (nuclear waste storage, residential). There were no differences in hunting and fishing rates, ranking of the severity of environmental problems, and willingness to expend federal funds as a function of distance of residence from SRS, but attitudes toward future land use differed significantly as a function of location of residence. Those living close to SRS were more willing to have the site used for factories, residential, nuclear material production and to store nuclear wastes than those living farther from the site. Our data on recreational rates, attitudes toward future land use, and willingness to expend federal funds to solve environmental problems reiterate the importance of assessing stakeholder attitudes toward decisions regarding future land use at DOE sites  相似文献

We report a meta-analytic examination of the value of five facets of family-friendly work environments (FFWEs) in reducing work/family conflict (WFC). Cumulation of 38 studies (total N = 13,605) suggests that facets of FFWE may provide less assistance to workers in managing WFC than one may hope, as none explained more than seven percent of the variance in WFC. A family-friendly work culture seems most influential in reducing WFC. Importantly, spousal support and FFWEs explain different portions of variance in WFC, suggesting that FFWEs are uniquely valuable to workers in achieving work/ family balance. Implications for research and practice are discussed. When authors reported separate correlations for different subgroups (e.g., males and females), samples, administrations (as in a longitudinal study), or measures of the same construct, those correlations were examined separately. The studies included in this meta-analysis are listed in the references prefixed with an asterisk.  相似文献
