Users of the Internet are stripped of voice inflections, body language, and other common cues of conversation-only their words are left. Some claim that the lack of these social cues and the lack of hierarchy in the structure of the Internet provide the potential for equality in cyberspace. Many others have shown, though, that the issues of power in cyberspace are similar to the issues of power in physical space. This article examines an intersection of feminism and cyberspace in the ethos of online discussion. It is a rhetorical analysis of two popular feminist newsgroups, alt.feminism and soc.feminism. Do these newsgroups create a feminist and inclusive space online? What are the rhetorical strategies that make an online space more or less inclusive of women? Usenet newsgroups reveal the rhetorical power of these bare words. Although no formal means of discrimination is built into Usenet newsgroup discussions, discrimination does occur through the subtle and not so subtle use of language. This article looks at how various characteristics of language are used on the two newsgroups. Though the ethos on such discussion forums is dynamic, the analysis reveals examples of how sarcastic questioning, strong assertions, accusatory disagreements, and sexistcomments can create a hostile and noninclusive ethos. 相似文献

Animating the graphics in electronic documents may increase readers’ willingness to study them but may impair or distort the processes of gist comprehension. Experiment 1 confirmed that, compared with static diagrams, animation increased readers willingness to study a range of graphic genres (maps, time-lines, drawings of unfamiliar objects). Total reading time was also increased but readers’ differential access of static and animated graphics confounded the interpretation of immediate and delayed retention tests. Experiment 2 contrasted the effects of accessing the graphics before or during reading. Scores on a quiz immediately after reading were significantly higher when the graphics were seen before rather than during reading, suggesting that readers found it difficult to integrate the graphics while still building the gist of the text. Scores on both an immediate and a delayed quiz were significantly higher when the graphics were static rather than animated. One pointer to the cause of the decrement with animated graphics was that the quiz performance of readers having animated graphics correlated with their scores on a picture memory test, whereas those of readers with static graphics did not. In contrast the delayed quiz scores of readers with static graphics showed a significant interaction with their performance on a digit memory task. Readers with high scores on digit memory benefited from accessing the graphics while reading, but readers with low scores on the digit test were impaired by such access during reading. This suggests that the cognitive skills needed for integrating text with animated graphics may differ from those needed for dealing with static graphics. 相似文献

The importance of quality in the provision of day care services for young children is well established. A project designed to address issues of assessing, maintaining and enhancing standards of service provision in the UK developed a set of self‐assessment materials for use in group day care settings. This paper describes a project to evaluate whether versions of the same materials might be effective in group day care settings in Hungary. Differences and similarities between service provision in the UK and Hungary are described. In a study involving 76 Hungarian day care centres, > 80% of staff involved thought using the materials raised their awareness of quality issues, although the materials did not have a significant impact on the quality of care provided. Key differences between service provision in the UK and Hungary are identified as influencing the potential effectiveness of the materials in assessing, maintaining and enhancing quality. 相似文献

Purpose: Some adults with type 2 diabetes mellitus (T2DM) have comorbidities and mobility impairments that limit their exercise capacity. In consideration of this, we developed and piloted a program called Active Steps for Diabetes for people with T2DM, comorbidities, and mobility impairments. The purpose of this paper was to report outcomes for the pilot program. Methods: Active Steps for Diabetes, an 8-week program, included instruction on diabetes self-care andgroup and home exercise programs. Twenty-two females (62.7 ± 6.1yrs) with T2DM and self-reported mobility impairments completed the program. Six participants used a walking aid. Outcome measures included two risk factors for coronary artery disease [daily physical activity and body mass index (BMI)], cardiovascular fitness (6-minute walk distance), and knowledge of diabetes-specific exercise guidelines. A two-way repeated measures ANOVA was used to compare outcomes before and after the program and between participants who did and did not use a walking aid. Results: Active Steps for Diabetes was effective in increasing daily physical activity in both groups of subjects (walking aid group: 2.6 days/week [95% confidence interval (CI) = 2.1 to 3.3]; no walking aid group: 1.9 days/week [95% CI=1.2 to 2.5]). This was accompanied by increases in 6-minute walk distances (walking aid group: 54.0 m [95% CI = 36.4 to 71.6]; no walking aid group: 62.6 m [95% CI=55.7 to 69.4]). Changes in BMI were not significant (walking aid group: −0.4 [95% CI = −1.2 to 0.4]; no walking aid group: −.24[95% CI = −.91 to .44]). Increases in knowledge of diabetes-specific exercise guidelines were observed in both groups (walking aid group: 18.8% [95% CI = 11.3 to 26.4]; no walking aid group: 19.3% [95% CI = 16.1 to 22.5]). Discussion:: Physical inactivity and low cardiovascular fitness are predictors of CAD morbidity and mortality in adults with T2DM. This pilot program suggests that a model for diabetes education, incorporating exercise programs developed by a physical therapist, may increase physical activity, improve endurance, and thereby potentially reduce CAD risk in people with T2DM and mobility impairments from comorbidities.Key Words: type 2 diabetes, physical activity 相似文献

Current awareness services are designed to keep users informed about recent developments based around user need profiles. In organisational settings, they may operate through both electronic and social interactions aimed at delivering information that is relevant, pertinent and current. Understanding these interactions can reveal the tensions in current awareness dissemination and help inform ways of making services more effective and efficient. We report an in-depth, observational study of electronic current awareness use within a large London law firm. The study found that selection, re-aggregation and forwarding of information by multiple actors gives rise to a complex sociotechnical distribution network. Knowledge management staff act as a layer of “intelligent filters” sensitive to complex, local information needs; their distribution decisions address multiple situational relevance factors in a situation fraught with information overload and restrictive time-pressures. Their decisions aim to optimise conflicting constraints of recall, precision and information quantity. Critical to this is the use of dynamic profile updates which propagate back through the network through formal and informal social interactions. This supports changes to situational relevance judgements and so allows the network to ‘self-tune’. These findings lead to design requirements, including that systems should support rapid assessment of information items against an individual’s interests; that it should be possible to organise information for different subsequent uses; and that there should be back-propagation from information consumers to providers, to tune the understanding of their information needs. 相似文献

A historical and theoretical analysis of the copyright environment demonstrates that both the economic rights associated with copyright and the moral rights often associated with copyright perform social functions. The latter have not been as universally embraced or adopted as the former. The lack of enthusiasm for moral rights is argued to be because the social utility of this aspect of the copyright regime has gone largely unrecognized. In fact, moral rights ensure that the information needs of the public are being met because they enhance the ability to assess the authority and reliability of information. While historically this has not been as important as enhancing the supply of information, a function performed by the economic rights of copyright, in the context of the new information environment, the role played by moral rights is becoming increasingly important. Our thesis also defines the appropriate scope of moral rights protection in copyright. 相似文献

Four year old children’s acquisition of print knowledge during electronic storybook reading 总被引:1,自引:0,他引:1
The experiment reported here explored the importance of engaging 4-year-old children’s interest in the print itself during
storybook reading. We explored the effect of computer animation of the print in order to draw the child’s attention to each
word as it was read. We also investigated the influence of illustrating that not all visual displays are readable print on
the child’s print knowledge. The measures of interest were print concept knowledge and early reading skill. Results indicated
that simply drawing children’s attention to the print during shared reading was insufficient to facilitate children’s learning
of print conventions, but this attention to print while hearing stories read did improve children’s letter reading. The child’s
active engagement with the print during shared story reading led to further improvements in written language skills, as illustrated
by gains in knowledge about print concepts. 相似文献
