Dominant approaches to teaching social studies often marginalize bilingual and bicultural students. This is particularly troubling because the explicit goal of the social studies is to cultivate civic participation. Educational inequalities are thus tied to political inequalities. In light of this, this article shares a narrative case study of the author's own bilingual and bicultural approach to teaching middle school civics at a dual-language American school in Mexico. Through the illustration of a comparative civics curriculum that incorporates translanguaging practices, the author argues that embracing bilingualism and biculturalism in the social studies can lead to more expansive possibilities for justice-oriented civic education.  相似文献

Urban green spaces, such as forest fragments, vacant lots, and community gardens, are increasingly highlighted as biodiversity refuges and are of growing interest to conservation. At the same time, the burgeoning urban garden movement partially seeks to ameliorate problems of food security. Arthropods link these two issues (conservation and food security) given their abundance, diversity, and role as providers of ecosystem services like pollination and pest control. Many previous studies of urban arthropods focused on a single taxon (e.g. order or family), and examined either local habitat drivers or effects of landscape characteristics. In contrast, we examined both local and landscape drivers of community patterns, and examined differences in abundance, richness, and trophic structure of arthropod communities in urban forest fragments, vacant lots, and community gardens. We sampled ground-foraging arthropods, collected data on 24 local habitat features (e.g., vegetation, ground cover, concrete), and examined land-cover types within 2 km of 12 study sites in Toledo, Ohio. We found that abundance and richness of urban arthropods differed by habitat type and that richness of ants and spiders, in particular, varied among lots, gardens, and forests. Several local and landscape factors correlated with changes in abundance, richness, and trophic composition of arthropods, and different factors were important for specific arthropod groups. Overwhelmingly, local factors were the predominant (80 % of interactions) driver of arthropods in this urban environment. These results indicate that park managers and gardeners alike may be able to manage forests and gardens to promote biodiversity of desired organisms and potentially improve ecosystem services within the urban landscape.  相似文献

Benefits of physical activity for those with arthritis are clear, yet physical activity is difficult to initiate and maintain. Self-efficacy is a key modifiable psychosocial determinant of physical activity. This study examined two scales for self-efficacy for exercise behavior (SEEB) to identify their strengths and weaknesses using item response theory (IRT) from community-based randomized controlled trials of physical activity programs in adults with arthritis. The 2 SEEB scales included the 9-item scale by Resnick developed with older adults and the 5-item scale by Marcus developed with employed adults. All IRT analyses were conducted using the graded-response model. IRT assumptions were assessed using both exploratory and confirmatory factor analysis. The IRT analyses indicated that these scales are precise and reliable measures for identifying people with arthritis and low SEEB. The Resnick SEEB scale is slightly more precise at lower levels of self-efficacy in older adults with arthritis.  相似文献

A New Empirically Weighted Monetary Aggregate for the United States   总被引:1,自引:0,他引:1  
This article uses an approach to long-run modeling proposed by Pesaran, Shin, and Smith (2001) to develop an empirically weighted broad monetary aggregate for the United States and to demonstrate the advantages of this type of aggregate from a monetary policy perspective. The new empirically weighted aggregate performs well in out-of-sample nominal income and inflation forecasting tests, and in respect of the latter is clearly superior to simple sum M2, Divisia M2, and simple sum M2+ (which includes stock and bond mutual funds) over the period 1991–2001.  相似文献

The leading United Kingdom food retailers have recently come under considerable scrutiny in respect of their reported profits, margins and accounting policies. Journalists and analysts as well as academics have focused on comparisons with continental European retailers. This paper argues that a number of factors are pertinent to the debate on performance in food retailing. The classification introduced (accountancy practices, cost structures, management structures and control and the environmental context), is illustrated using UK and French company data. The conclusion is drawn that it is not just simple differences but also the operational dimensions of company practices relating to these factors which are important determinants of performance. Simplistic headline comparisons are too inaccurate to be meaningful.  相似文献

Lotteries (i.e., probabilistic bonus contingencies) are an established intervention in Organizational Behavior Management. Although common, there are many permutations of lotteries used in literature and they are often combined with other interventions. One key variable that may influence the effectiveness of lotteries are the odds that the lottery will pay out to those who earn entry. The current investigation evaluated a lottery intervention with varied payout chances (25%, 12%, 6%, or 3%). A 6% chance of winning was the lowest odds of winning where responding was reliably maintained across two participants. Implications of these results and future direction for research are discussed below.  相似文献

New retail locations and formats and changing consumer capabilities and behaviours (including “switching”) have encouraged “outshopping” from rural to urban areas. Rural areas have been suffering from a decline in the provision of services, including retailing. One “solution” has been the strengthening of market towns in rural areas by the development of new major retail stores. The effects of this are perhaps not fully understood, particularly where the rural area comprises a network of towns rather than a single centre. Three comparable consumer surveys (1988, 1998, 2004) of shopping behaviour in the Scottish Borders are analysed. Consumer place and store switching data are used to examine the impact of new retail opportunities on shopping patterns. Two different switching strands are identified: clawback and redistribution. Redistribution within the rural network is a new finding.  相似文献

This article documents some findings of a sociological research project which was done in West Germany from 1970 ‐ 1973 (Dannecker/Reiche 1974). 139 contact‐persons, chosen by the authors, distributed 1617 questionnaires to homosexuals. 789 were filled out and sent back and constitute our sample.

The complete research project comprises six themes: coming out; homosexual subculture; homosexual friendships; sexuality of homosexuals; jobs and the employments of homosexuals; the collective neurosis of homosexuals.  相似文献
