泰勒·斯威夫特:我歌写我心,错爱亦无憾

在纳什维尔一个冰冷的二月天,斯威夫特在SIR录音室为其进行中的47城巡回演唱会进行排练,宣传自己的专辑《红》(2012)。她当时正漫不经心地弹着一把镶着珍珠母的泰勒吉他,那是她最钟爱的品牌。斯威夫特擅长写很好听的流行歌曲,这些歌余音袅袅,萦绕你心头就像是棒棒糖粘在你的头发上一样。她的嗓音有时会为人诟病,因为纤细单薄,但是听着很甜美优雅,还带着那么点乡村鼻音。斯威夫特在自己的录影带中塑造笨拙可爱的形象,通常在其中她扮演不     

Adding Value to Usage Statistics: The Journal Usage Statistics Portal (JUSP) Enhancements

The Journal Usage Statistics Portal (JUSP) provides a single point of access to journal usage data from participating publishers on behalf of UK academic libraries. In August 2011 JISC awarded funding to develop two value-added enhancements to support existing service provision and help libraries assess the value and impact of e-resources. This article describes the development of these enhancements and their impact.     

Classifying The Pseudo-Turpin Chronicle

This study focuses on the library classification practices of The Pseudo-Turpin Chronicle. The Pseudo-Turpin Chronicle has been called an enigmatic work by scholars, and the mystery has carried into library classification. The work's language of origin is not its national language. The work's varied acceptance as fact and fiction also plays into its classification practices. For many years, The Pseudo-Turpin was believed to be a true account, so it was classed as history. While the work has standard literature classification numbers, even its literature classification practices are varied.     

Measurement Uncertainty in Racial and Ethnic Identification Among Adolescents of Mixed Ancestry: A Latent Variable Approach

In this article, we operationalize identification of mixed racial and ethnic ancestry among adolescents as a latent variable to (a) account for measurement uncertainty, and (b) compare alternative wording formats for racial and ethnic self-categorization in surveys. Two latent variable models were fit to multiple mixed-ancestry indicator data from 1,738 adolescents in New England. The first, a mixture factor model, accounts for the zero-inflated mixture distribution underlying mixed-ancestry identification. Alternatively, a latent class model allows classification distinction between relatively ambiguous versus unambiguous mixed-ancestry responses. Comparison of individual indicators reveals that the Census 2000 survey version estimates higher prevalence of mixed ancestry but is less sensitive to relative certainty of identification than are alternate survey versions (i.e., offering a “mixed” check box option, allowing a written response). Ease of coding and missing data are also considered in discussing the relative merit of individual mixed-ancestry indicators among adolescents.     

A review of the foundational processes that influence beliefs in climate change: opportunities for environmental education research

Recently, many organizations involved in environmental education have initiated programs that aim to educate visitors or other publics who interact with nature-based resources about the impacts and landscape transformations occurring because of climatic changes. However, many psychological, human-evolutionary, and social–ecological processes that impede individuals’ ability to notice or respond to (e.g. adaptation and mitigation behaviors) climate impacts in nature-based areas, or in their urban-based home communities, may influence the educational process. By reviewing and examining these foundational processes and their potential influence on an audience’s attitudes and beliefs towards climate change, we outline and explain their importance for research. Based on these important psychological, human-evolutionary, and social–ecological processes, the authors conclude by identifying how researchers can investigate the influence of these processes and their potential impacts on environmental education outcomes.     

Words for Artworks: The Aesthetics of Meaning Making

In this article we introduce a research strategy that involves the making of visual maps by individuals in response to their interactions with artworks. The maps record the meaning‐making processes involved in the encounters and provide us with permanent records of otherwise ephemeral experiences. The case study presented here provides data for comparisons between three visits each to two artworks exhibited at the Calouste Gulbenkian Modern Art Centre in Lisbon. We conclude that our meaning‐making strategy is important for its own heuristic research value in both formal and non‐formal educational contexts, as well as providing an instrument for the training of teachers and museum educators.     

Integrating privacy studies into teacher education curricula

Abstract

Privacy studies may be seen by some teacher educators as being ‘anti-technology’ in their character, with the potential to dim the enthusiasm of future teachers for new technological initiatives. However, privacy is taking on new significance in an age of the Internet and advanced information technologies, as the examples and sources outlined in this article demonstrate. Privacy issues have a strong influence on various pressing international political and economic concerns, and thus add important dimensions to curricula. Some technological developments (such as encryption) also provide hands-on dimensions to privacy topics that are likely to whet the interests of many students. Teacher educators can work to introduce privacy notions to future teachers in ways that will enhance both their information technology studies and their understanding of other curricular areas (including citizenship, business, and social studies). As described in this article, privacy exercises, scenarios, and hands-on laboratory sessions were provided in several teacher education courses in the United States. What teacher educators do in relation to privacy studies will help determine the future character of discourse and the direction of technological development pertaining to privacy.     

No effect of glutamine supplementation and hyperoxia on oxidative metabolism and performance during high-intensity exercise

Abstract

Glutamine enhances the exercise-induced expansion of the tricarboxylic acid intermediate pool. The aim of the present study was to determine whether oral glutamine, alone or in combination with hyperoxia, influenced oxidative metabolism and cycle time-trial performance. Eight participants consumed either placebo or 0.125 g · kg body mass^?1 of glutamine in 5 ml · kg body mass^?1 placebo 1 h before exercise in normoxic (control and glutamine respectively) or hyperoxic (FiO₂ = 50%; hyperoxia and hyperoxia + glutamine respectively) conditions. Participants then cycled for 6 min at 70% maximal oxygen uptake ([Vdot]O_2max) immediately before completing a brief high-intensity time-trial (～4 min) during which a pre-determined volume of work was completed as fast as possible. The increment in pulmonary oxygen uptake during the performance test (Δ[Vdot]O_2max, P = 0.02) and exercise performance (control: 243 s, s _x  = 7; glutamine: 242 s, s _x  = 3; hyperoxia: 231 s, s _x  = 3; hyperoxia + glutamine: 228 s, s _x  = 5; P < 0.01) were significantly improved in hyperoxic conditions. There was some evidence that glutamine ingestion increased Δ[Vdot]O_2max in normoxia, but not hyperoxia (interaction drink/FiO₂, P = 0.04), but there was no main effect or impact on performance. Overall, the data show no effect of glutamine ingestion either alone or in combination with hyperoxia, and thus no limiting effect of the tricarboxylic acid intermediate pool size, on oxidative metabolism and performance during maximal exercise.     

Predicting continued use of online teacher professional development and the influence of social presence and sociability

This study examined how a well‐established Technology Acceptance Model (TAM) could predict teachers' intentions to continue using e‐learning for professional development based on perceived ease of use and usefulness. Although studies have shown social interactions are important to teachers, no study has analyzed the mediating influence of social presence and sociability within e‐learning professional development. Therefore, the original TAM was expanded to encompass user perceptions of social presence and sociability. Structural equation modeling was used to measure the mediating affects on their intention to continue using e‐learning for their professional development. The results indicate that the expanded hypothesized model was a good predictor of continuance intention. Perceived ease of use, perceived usefulness and social presence were found to be significant determinants of teachers' intent to continue using e‐learning to meet their future professional development needs. The results have implications for educational leaders, designers and facilitators who want to promote teacher online professional development and embed e‐learning conditions that will be readily embraced by classroom teachers.
