Abstract This paper is an extract from the report of a case study into the programme supply make/buy decision of the UK's main terrestrial commercial television channel, ITV. It compares this decision in the start‐up period (1954–1964) with the latest operating period (1992–2001) to show how programme supply arrangements have changed. It also provides an interpretation for why these changes have occurred. ITV's continuing dominance of the UK terrestrial commercial market permits this paper to be examined as a country specific case of how organising structures for programme supply evolve. Due to the concise nature of this paper, only one aspect of the make/buy decision is compared: changes to the structure within which programme supply decisions are determined. The analysis is based on state archives and interviews. It is concluded that contractual ambiguity and political fear of the social impact of commercial television initially inhibited the adoption of a competitive programme supply structure. Later changes to this structure are attributed to increased contract specification and a more market‐oriented approach. A brief theoretical interpretation based on transaction cost economics, economic sociology, and the property rights literature is provided. 相似文献

This study investigated changes in teachers' and students' perceptions of students' effort, strategy use, and academic difficulties when strategy instruction was infused into the classroom curriculum. The sample consisted of 201 students with learning disabilities, 210 average achievers, and 57 teachers from Grades 4–9 in two urban and suburban communities. After six months of classroom‐based strategy instruction, students with learning disabilities reported more consistent use of strategies with their schoolwork and perceived themselves as struggling less in reading, writing, and spelling. Teachers perceived the students with learning disabilities as more strategic and as applying more effort to their schoolwork. Teachers also perceived their students as showing significant improvements in spelling, regardless of whether they had learning disabilities. These findings extended the results of previous investigations and indicated the small, positive impact of classroom‐based strategy instruction. Further investigations are critical to evaluate the generalizability of these findings. 相似文献

Online surveys are increasingly used in educational research, yet little attention has focused on ethical issues associated with their use in educational settings. Here, we draw on the broader literature to discuss 5 key ethical issues in the context of educational survey research: dual teacher/researcher roles; informed consent; use of incentives; privacy, anonymity, and confidentiality; and data quality. We illustrate methods of addressing these issues with our experiences conducing online surveys in educational contexts. Moving beyond the procedural ethics approach commonly adopted in quantitative educational research, we recommend adopting a situated/process ethics approach to identify and respond to ethical issues that may arise during the conduct, analysis, and reporting of online survey research. The benefits of online surveying in comparison to traditional survey methods are highlighted, including the potential for online surveys to provide ethically defensible methods of conducting research that would not be feasible in offline education research settings. 相似文献

This paper presents data from a study of young adults with Down syndrome who were born either just before, or during the period when radical changes to special education services for people with intellectual disabilities were introduced. The specific aim of the study was to examine the development of language and literacy skills in a group of young adults with Down syndrome, some of whom had been educated at a time when there was an increase in expectations for achievement and opportunity to learn. Results showed that all but one of the young adults had learned to read, though for some, these skills were limited. In general, there was evidence of a positive relationship between age (for those born after 1970), attendance at an integrated school situation, and the achievement of more advanced reading and language skills. It was also evident that learning to read provides both a functional daily living skill and a satisfying recreational activity for young adults with Down syndrome. 相似文献

This phenomenological study explored six single mothers’ experiences of support at their young children’s school. Themes resulting from interpretative phenomenological analysis suggest the single mothers experienced tangible (e.g., school resources, school-wide events, structural flexibility, teachers’ formal communication) and intangible (e.g., caring relationships with school faculty and staff, experiencing teachers as parenting partners, perceiving acceptance from the school environment) forms of support from their children’s school. Furthermore, results suggest these single mothers experienced intangible supports more prominently than tangible forms of support. The support needs of these single mothers at their young children’s school were also explored including the mothers’ desire for stronger relationships with other parents and families at the school. 相似文献

Although there has been a great deal of research into Collaborative Information Retrieval (CIR) and Collaborative Information Seeking (CIS), the majority has assumed that team members have the same level of unrestricted access to underlying information. However, observations from different domains (e.g. healthcare, business, etc.) have suggested that collaboration sometimes involves people with differing levels of access to underlying information. This type of scenario has been referred to as Multi-Level Collaborative Information Retrieval (MLCIR). To the best of our knowledge, no studies have been conducted to investigate the effect of awareness, an existing CIR/CIS concept, on MLCIR. To address this gap in current knowledge, we conducted two separate user studies using a total of 5 different collaborative search interfaces and 3 information access scenarios. A number of Information Retrieval (IR), CIS and CIR evaluation metrics, as well as questionnaires were used to compare the interfaces. Design interviews were also conducted after evaluations to obtain qualitative feedback from participants. Results suggested that query properties such as time spent on query, query popularity and query effectiveness could allow users to obtain information about team's search performance and implicitly suggest better queries without disclosing sensitive data. Besides, having access to a history of intersecting viewed, relevant and bookmarked documents could provide similar positive effect as query properties. Also, it was found that being able to easily identify different team members and their actions is important for users in MLCIR. Based on our findings, we provide important design recommendations to help develop new CIR and MLCIR interfaces. 相似文献

Failure to thrive (FTT) is a frequent cause for the admission of infants to the hospital. Such hospitalizations are often lengthy and expensive, and usually do not contribute to an understanding of the etiology of FTT. Generally, organic causes of FTT can be ruled out by a thorough history and physical examination. In this study two groups were examined: 17 infants who were admitted to foster medical placement homes (MPH), private homes with specially trained parents; and a comparison group of 18 infants who were treated in a more traditional way with diagnostic hospitalization. The groups were similar in all regards prior to admission. All infants were less than a year of age. Family disruption was a prominent feature in both groups, but socio-demographic analysis showed them to be similar in all areas studied. The comparison group gained an average of 276 grams in the hospital over 8.6 days. The MPH group gained 362 grams in the hospital over 8.7 days, with an additional 1270 grams in the medical placement home over 31.1 days. Five children were admitted to the medical placement home without hospitalization. After correcting for an expected weight gain of 15 grams per day (normal growth), the comparison group showed a catch-up growth of 16 gms/day, while the MPH group gained 29 gms/day in excess of expectation, almost twice the comparison group. A 100-gram weight gain cost +308 in the MPH program and +1,635 in the traditional approach. This five-fold difference was felt to be a significant deterrent to the continuing approach of admitting children to the hospital for for the workup of FTT.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
