Within the cut-throat world of newspaper advertising the newspapers of Britain's Women's Social and Political Union (WSPU) Votes for Women and the Suffragette managed to achieve a balance that has often proved to be an impossible challenge for social movement press—namely the maintenance of a highly political stance whilst simultaneously exploiting the market system with advertising and merchandising. When the militant papers advocated window smashing of West End stores in 1912–1913, the companies who were the target still took advertisements. Why? What was the relationship between news values, militant violence and advertising income? ‘Do-it-yourself’ journalism operated within a context of ethical consumerism and promotionally orientated militancy. This resulted in newspaper connections between politics, commerce and a distinct market profile, evident in the customisation of advertising, retailer dialogue with militants and longer-term loyalty—symptomatic of a wider trend towards newspaper commercialism during this period.  相似文献

Previous studies implicate suprasegmental phonology in reading acquisition. However, little is known about how suprasegmental sensitivity develops or how it contributes to reading. Here, 130 Spanish primary-school children participated in this 2-year longitudinal study. Nonlinguistic rhythm, lexical-stress sensitivity and metrical-stress sensitivity, along with phonological awareness, vocabulary, nonverbal intelligence, and reading aloud, were assessed on five occasions. Results suggest that prosody abilities have different developmental trajectories and that prosody explains unique variance in reading beyond that explained by other factors. There was some evidence that the contribution of each prosody skill occurred at different phases in reading development. Nonlinguistic rhythm, lexical-stress sensitivity, and metrical-stress sensitivity assessed at the end of kindergarten, the start of Grade 1, and the end of Grade 1, respectively, predicted reading performance 6 months later. Nevertheless, sample size and reliability temper the conclusions that can be made. The implications of prosody skills for literacy development are discussed.  相似文献

Recent research has demonstrated that slight increases of inter-letter spacing have a positive impact on skilled readers' recognition of visually presented words. In the present study, we examined whether this effect generalises to young normal readers and readers with developmental dyslexia, and whether increased inter-letter spacing affects the reading times and comprehension of a short text. To that end, we conducted a series of lexical decision and continuous reading experiments in which words were presented with the default settings or with a small increase in inter-letter spacing. Increased spacing produced shorter word identification times not only with adult skilled readers (Experiment 1), but also with young normal readers (Grade 2 and Grade 4 children; Experiment 2) and, even to a larger degree, with readers with dyslexia (Experiments 3 and 4). These experiments suggest that slight increases in inter-letter spacing would improve the readability of texts aimed at children, especially those with dyslexia.  相似文献

There are signs that teams are becoming more popular in ethnographic research. New technology and, in the UK, the Research Assessment Exercise have facilitated the establishment and continuance of teams. In this paper, the authors discuss their experiences in one particular research team in recent years. Securing adequate funding has been the essential structural prerequisite. The authors distinguish among project, federated, and whole teams, depending on function and level of analysis. They consider team structure, approach, business, and processes, and the relationship between individual and team. Teamwork has enabled a wider and deeper coverage of work, a broader comparative base, and multiple researcher triangulation. The team provides a forum for the discussion of ethical issues, an immediate supportive reference group. It has opened up horizons, and promoted individual change and development. It has aided analysis and writing, and promoted clearer and more robust arguments. The article concludes with some caveats.  相似文献

This work is devoted to the study of symmetric control systems. It establishes a relation between internal symmetry and external one for a linear invariant control system having n real simple poles. The symmetric stabilization problem is studied using a symmetric feedback gain such that the output control stabilizes the closed-loop system. A necessary and sufficient condition is given to solve this stabilization problem for a symmetric control system (A,B,C) and a generalized symmetric control system (E,A,B,C).  相似文献

The decade of the 1970s heralded a major research effort into mariculture of economically important red and brown seaweeds. Limited and declining natural populations, lack of synthetic substitutes for the phycocolloids, and their upwardly spiralling costs have emphasized the need for more research in this area. Algal mariculture is now technically and scientifically feasible, but the economic realities are still undetermined. This article examines what is known about seaweed mariculture and discusses where future research efforts must go.  相似文献

Findings are presented from a qualitative longitudinal collective case study of 29 teachers newly appointed to rural or remote schools in Western Australia. All participants experienced stress and articulated coping strategies in response: direct-action, palliative and avoidant strategies. Where protective structures and processes existed in environments, teachers employed direct-action problem-solving strategies. Avoidant strategies were more common in young and mature-aged novices, rather than experienced teachers.Three critical times were identified to support adaptation: first weeks of appointment for information, first semester for assistance, support, feedback for development of competence and three months before the year-end for stability and certainty.  相似文献
