Patterns of practice: a reflection on the development of quantitative/mixed methodologies capturing everyday life related to water consumption in the UK

There is a growing body of research arguing the relevance of practice approaches to understand resource consumption, and to highlight alternative pathways to sustainability. These practice approaches offer an alternative conceptualisation of demand and have been demonstrated largely by qualitative research, particularly in the work on water and energy consumption in the home. However, these historical narratives and qualitative research have not, to date, lead to the development of quantitative or mixed methodologies that could potentially reflect the diversity of performances of practice across populations in a more systematic way. This paper reflects, critically, on one such attempt to scale a practice-based perspective into a quantitative survey on water consumption and practice in homes in the south and South-East of England. The use of quantitative and mixed methodology has substantial potential – from translating practice-based research to policy; developing indictors to track patterns of practices as they change over time; and the exploration of methodologies that reflect the bundling and coordination of practices associated with water use inside and outside the home. The benefits and utility of such a methodological approach are highlighted as cautions and future research directions.

The origins of a source: Edward Long,Coromantee slave revolts and The History of Jamaica

Since the 1960s, historians of the early-modern era have been working with colonial sources to uncover the ways that Africans with connections to the Gold Coast – often known as ‘Coromantees’ in the Anglo-American colonies – shaped the history of the Atlantic World. One of the most influential primary sources used in this literature is a 32-page section of the second volume of The History of Jamaica, written by the planter-historian Edward Long in 1774. ‘The origins of a source’ uses Long’s life and works, both published and unpublished, to tell the story of this source’s creation. In doing so, it provides a detailed case study for how a prominent and controversial intellectual acquired knowledge of African culture, and then repurposed and deployed that knowledge as a tool in the abolitionist debates. It argues that the political context of abolition is essential to understanding Long’s writings on the Coromantee.     

De los Derechos Humanos: Reimagining Civics in Bilingual & Bicultural Settings

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.     

Local and landscape drivers of arthropod abundance,richness, and trophic composition in urban habitats

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.     

Item-response-theory analysis of two scales for self-efficacy for exercise behavior in people with arthritis

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.     

A New Empirically Weighted Monetary Aggregate for the United States

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.     

学术论文写作的"注意事项"

选题要凸现真正具有创新性的“问题意识”,在收集资料的过程中要努力地使得“自己的思想”建基于“传统的资源”并充分地敞开,要重视包括结构、语言、注释在内的写作技巧,尤其要在创作学术论文的整个过程中贯彻以诚信为本的“研究伦理”,——这一学术论文写作的“注意事项”看似老生常谈,但现实却仍然要求我们在编辑学的意义上重申之、在专业研究的意义上激活之、在伦理学的意义上警醒之。     

Performance in Food Retailing: A Cross-national Consideration and Comparison of Retail Margins

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.     

Further Effects of Lottery Odds on Responding

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.
