Last year 1279 professional authors completed a lengthy questionnaire on their use of, and attitudes towards, technological tools for writing and publishing. The data were analysed quantitatively, by examining the most frequent responses to items on the questionnaire, and qualitatively, by looking closely at details illuminating the relationship between authors and publishers. The results, for present purposes, are divided into three broad bands of interest: first, what types of writing software authors are currently using; second, what the implications of using authors' disks in the publication chain are; and third, how technology alters perceptions of the copy as a unit of sale. Findings suggest that though authors are operating at basic levels, they have embraced technology with more enthusiasm than their publishers. The challenge facing those involved in books is to make provision for presenting and displaying work in electronic form: to improve contracts and licensing agreements, and to disseminate information on technology to authors.Funded by the British National Bibliography Reseach Fund.© Jane Dorner, 1991 相似文献

The views of specialists (academics, librarians, publishers and information scientists) on trends in scholarly communications were canvassed by means of structured questions. A greater commonality of views was found than might have been expected. 相似文献

ABSTRACTThis paper examines how conservators engage with uncertainty when creating preventive conservation strategies. It argues that by recognising contexts in which uncertainty will be encountered conservators can develop effective management strategies. A typology of uncertainty explores a range of categories of uncertainty, their experience in preventive conservation and identifies distinct approaches to manage them. Managing uncertainty may include acts of defining its parameters, exposing and resolving through communication or protecting from with contingency. Whatever approach is adopted it must be accepted that uncertainty cannot be avoided. It is important therefore to aim to live well with uncertainty and the paper advocates for preventive conservation applications of strategies recommended in health care for patients with life-threatening illnesses. These strategies include working on things that can be controlled, goal setting, acceptance and factoring in emotions. The ability to identify contexts in which uncertainty is inbuilt should trigger those concerned with preventive conservation to activate strategies developed for managing and living well with uncertainty. 相似文献

AbstractMaternal dietary habits influence maternal and foetal health, representing a pathway for intervention to maximise pregnancy outcomes. Advice on energy intake is provided on a trimester basis, with no additional calories required in the first trimester and an additional 340?kcal?d?1 and 452?kcal?d?1 needed for the second and third trimesters. Energy intake depends on pre-gravid body mass index (BMI); underweight women are recommended an increase of 150, 200 and 300?kcal?d?1 during the first, second and third trimester, normal weight women an increase of 0, 350 and 500?kcal?d?1 and obese women an increase of 0, 450 and 350?kcal?day?1. The recommendations for carbohydrate and protein intake are 175?g?d?1 and 0.88–1.1?g?kgBM?d?1, with no change to fat intake. The number of pre-gravid obese women is rising; therefore, we need to regulate weight in women of childbearing age and limit gestational weight gain to within the recommended ranges [overweight women 6.8–11.3?kg and obese women 5.0–9.1?kg]. This can be achieved using nutritional interventions, as dietary changes have been shown to help with gestational weight management. As pregnancy has been identified as a risk factor for the development of obesity, normal weight women should gain 11.5–16.0?kg during pregnancy. While some research has shown that dietary interventions help to regulate gestational weight gain and promote postpartum weight loss to some extent, future research is needed to provide safe and effective guidelines to maximise these effects, while benefitting maternal and foetal health. 相似文献

This article describes the adaptation of ‘story grammar’ to developing the subject understanding and literacy of 14–16-year-old students. ‘Story grammar” analyses the structure of episodes of a typical story and it was developed through research into the narrative development of younger, frequently language-delayed, children. Reasons for expecting this story grammar to provide a helpful basis for teaching older students are summarized. An application of story grammar in teaching business studies is described through the activities designed for students and evidence from students' work. Implications for understanding of literacy in a subject context are discussed. 相似文献

Reflections about the use of critically reflexive praxis by academic/practitioners are offered based on a case study of a formative evaluation of Circles® USA, a nonprofit organization coordinating initiatives across the U.S. working to move families out of poverty. Critically reflexive praxis is theorized as featuring several themes including acknowledging different levels of context, critical dialogue with collaborators, engaging cultural difference and intersectionalities, problematizing power relations and relationships among researchers and collaborators, and occurring throughout the research project. Examples of critical dialogic reflexivity and navigating common tensions that emerge throughout such community engagement projects are detailed during three phases: planning and design; fieldwork and interviews; and outcomes, applications, and implications. 相似文献
