Measures of word recognition (REC) and two component skills, phonological coding (PHON) and orthographic coding (ORTH), were subjected to multivariate behavioral genetic analysis. Data were obtained from a sample of identical and fraternal twin pairs wherein at least one member of each pair was reading disabled (RD), and from a sample of twins wherein both members of each pair read in the normal range. Confirmatory factor analysis was used to fit the genetic, common environmental, and specific environmental covariance components for REC, PHON, and ORTH within the RD and normal simples. The resulting heritability estimates for REC, PHON, and ORTH were 0.59, 0.41, and 0.05 in the RD sample, and 0.35, 0.52, and 0.20 in the normal sample. After dropping the nonsignificant common environment parameters from the models, the genetic correlations between REC and PHON and between REC and ORTH were respectively 0.81 and 0.45 in the RD sample, and 0.68 and 0.45 in the normal sample. Differences between the genetic correlations were significant in the RD sample (p<0.005), marginally significant in the normal sample (p<0.10), and highly significant in the combined sample (p<0.001), indicating that genetic influences on individual differences in REC are more strongly related to genetic variance in PHON than in ORTH. These results are consistent with previous demonstrations of substantial genetic covariance between the disabled group's deficits in REC and PHON, but not between REC and ORTH (Olson et al., 1989; Olson and Rack, 1990). 相似文献

A standardized procedure was developed for eliciting those details of a library's service policies that are important to its users and for recording the data by checking appropriate categories on a form. This inventory procedure covers the entire spectrum of user services and accommodates a wide range of policies. The inventory was originally designed for use by trained interviewers in largescale surveys of academic medical libraries. However, it is also suitable for other kinds of libraries, and the Interview Guide and Checklist can be used for a self-survey by library staff. In addition to survey use, the inventory has a variety of educational, administrative, managerial, and research applications. A method for weighting the categorical inventory data to reflect the relative desirability of different policies makes it possible to calculate scores indicating how a library's policies compare with those of an "optimal" library. An analogous inventory of the services a library provides to other libraries was developed for surveying major backup resources in the medical library system. 相似文献

ABSTRACT We compared cardiometabolic demand and post-exercise enjoyment between continuous walking (CW) and time- and intensity-matched interval walking (IW) in insufficiently active adults. Sixteen individuals (13 females and three males, age 25.3 ± 11.1 years) completed one CW and one IW session lasting 30 min in a randomised-counterbalanced design. For CW, participants walked at a mean intensity of 65–70% predicted maximum heart rate (HRmax). For IW, participants alternated between 3 min at 80% HRmax and 2 min at 50% HRmax. Expired gas was measured throughout each protocol. Participants rated post-exercise enjoyment following each protocol. Mean HR and V˙O2 showed small positive differences in IW vs. CW (2, 95%CL 0, 4 beat.min?1; d = 0.23, 95%CL 0.06, 0.41 and 1.4, 95%CL 1.2 ml.kg?1.min?1, d = 0.36, 95%CL 0.05, 0.65, respectively). There was a medium positive difference in overall kcal expenditure in IW vs. CW (25, 95%CL 7 kcal, d = 0.58, 95%CL 0.33, 0.82). Post-exercise enjoyment was moderately greater following IW vs. CW (9.1, 95%CL 1.4, 16.8 AU, d = 0.62, 95%CL 0.06, 0.90), with 75% of participants reporting IW as more enjoyable. Interval walking elicits meaningfully greater energy expenditure and is more enjoyable than CW in insufficiently active, healthy adults. 相似文献

The Gutenberg‐e project was created as an experiment to explore whether peer‐reviewed, born‐digital monographs would alter the way in which historical scholarship is presented, whether scholars would receive the same professional credit for these publications as for work published in print, and whether the project would enable publication of monographs that would otherwise be turned down by university presses for financial reasons. The project reached the following conclusions: authors and publishing staff collaborated in creating new models of scholarship and writing; over the course of the project, attitudes toward digital publications evolved toward acceptance of this new form of publication; the time and costs involved in creating these models exceeded expectations; continued experimentation is necessary in order to keep up with authors' growing expectations in publishing digital scholarship. 相似文献

Novels that prioritise the connectedness and strength of girls’ friendships without employing the pervasive trope of “mean
girls”—those who typically divide in order to conquer other girls—are potentially empowering in their refusal to perpetuate
limited and binary accounts of adolescent femininity. While Ann Brashares’ cult novel (now film), The Sisterhood of the Traveling Pants (2005a; originally 2002) appears to be representative of this textual shift, underpinning the overt call to value girls’ relationships
is a deeply conservative, assimilationist narrative that relies on an acceptance of traditional patriarchal values. This article
analyses the ways in which the novel appropriates “multicultural difference” to valorise, sustain and naturalise the central
position and authority of patriarchy in the lives of young girls, regardless of their cultural heritage.
Kate McInally currently works as a research fellow, and teaches children’s literature at Deakin University, Burwood, Australia.
Her particular research interests are feminist, queer and Deleuzean theory, representations of girl–girl desire in young adult
fiction, and multicultural children’s fiction. 相似文献

How can we use ICT to enhance the quality of pupil learning? The case study below deliberately embedded ICT within the context of an existing scheme of work to develop 11–12 year olds’ understanding of the skills and processes of historical investigation. It also mapped onto the existing teaching styles of the teachers involved, and reflected their orientation—beliefs and values. The role for the ICT was to present the pupils with a problem that would intrigue, excite and motivate them. Accordingly, we asked them to act in role as assistants to Harry and Hermione in investigating the strange death of Sam Woodhouse in 1822. The pupils carried out the investigation using a hyperlinked set of clues. They had undertaken two identical kinds of investigation earlier in the year. One was a murder mystery, the other the disappearance of the Princes in the Tower in 1483. For both these mysteries the clues were on cards. Comparisons of the results of the ICT mystery with those of the earlier two investigations suggest that the hyperlink version was equally effective in terms of developing understanding, with some clear advantages in developing pupils’ overall understanding of the problem and ability to make links between disparate clues and pieces of information. 相似文献

HIV remains a significant health concern entering the fourth decade of the epidemic [Centers for Disease Control and Prevention. 2014. HIV basics. Retrieved from http://www.cdc.gov/hiv/basics/index.html], and people living with HIV continue to grapple with stigma. This study uses Leary and Schreindorfer's [1998. The stigmatization of HIV and AIDS: Rubbing salt in the wound. In V. J. Derlega &; A. P. Barbee (Eds.), HIV and social interaction (pp. 12–29). Thousand Oaks, CA: Sage] conceptualization of stigma to explore prior stigmatization on reasons for and against future disclosures. We interviewed HIV+ individuals (N?=?59) and used a combination of deductive and inductive coding to analyze participants’ responses. Deductive codes consisted of four stigma characteristics (pose a threat to others’ health and safety, deviate from group standards, create negative emotional reactions in others, and failure to contribute), experiences of feeling stigmatized due to HIV status (yes or no), and the degree to which HIV stigma was a concern (major, minor, or no concern). Inductive coding identified examples of perceived and experienced stigma and stigma concerns on future disclosure decision-making. Practical implications discuss individual, institutional, and societal stigma-reduction interventions and programs. 相似文献

The purpose of this study was to determine the differences between third and sixth grade female and male students when retelling orally a story read silently. The students' retelling of the story was analyzed by comparing how closely, both structurally and linguistically, they paralleled the T-units or communication units of the author. In general, female students performed significantly differently than did male students. The researchers examine these differences in light of recent research in the area of gender differences. 相似文献

In the years since Michael Brown’s death, the hashtag #HandsUpDontShoot has been criticized for supposedly misrepresenting forensic evidence as framed by the Department of Justice. However, an expressive pull has kept alive both the hashtag and the sentiment behind it. The images of #HandsUpDontShoot are compelling in that they offer a glimpse into lived experiences that are often dismissed, ignored, or refuted. In this essay, I trace the aesthetic features of the #HandsUpDontShoot images, which foreground shocking juxtapositions between nonviolent protesters and militarized police forces, to the hashtag’s historical analogue: antilynching photography. Antilynching photography often utilized the aesthetic techniques of remediation, recontextualization, and juxtaposition—aesthetic features used prominently in today’s digital and remix cultures. By noting #HandsUpDontShoot’s use of these same techniques, I illuminate the ways in which Twitter’s connective affordances shape the viewer’s encounter with the images to engender ethical witnessing by affectively linking Brown’s death to shared material experiences of racial minorities. Such encounters propel witnesses beyond distanced objectification and toward an embodied reckoning of those experiences. 相似文献
