Forecasts indicate a growing demand for digital content around the world. Converting to digital content can open up countless new revenue possibilities. Adding alternate channels may be worth consideration, but what are the options and what does it take to utilize them effectively? This article explores the opportunities that potentially exist for publishers with content that may be digitized and distributed to global markets. A brief review of the current marketplace is also incorporated, including current players and trends. Finally, an analysis of some of the potential issues, challenges and pitfalls is presented in context of delving into a new international digital content distribution strategy. 相似文献

In this article we present Supervised Semantic Indexing which defines a class of nonlinear (quadratic) models that are discriminatively
trained to directly map from the word content in a query-document or document-document pair to a ranking score. Like Latent
Semantic Indexing (LSI), our models take account of correlations between words (synonymy, polysemy). However, unlike LSI our
models are trained from a supervised signal directly on the ranking task of interest, which we argue is the reason for our
superior results. As the query and target texts are modeled separately, our approach is easily generalized to different retrieval
tasks, such as cross-language retrieval or online advertising placement. Dealing with models on all pairs of words features
is computationally challenging. We propose several improvements to our basic model for addressing this issue, including low
rank (but diagonal preserving) representations, correlated feature hashing and sparsification. We provide an empirical study
of all these methods on retrieval tasks based on Wikipedia documents as well as an Internet advertisement task. We obtain
state-of-the-art performance while providing realistically scalable methods. 相似文献

In this paper the authors reflect on their experiences of being academic developers and suggest how our profession might advance in the future. Our inquiry focuses on academic development and how we can support our clients more effectively. We propose that the profession of academic development should aim for academic status with many more research‐active staff contributing to its knowledge base. If this profession were located within the already recognized research field of higher education, we believe a number of potential benefits could accrue. These include a new level of professional standing, greater efficiency in our universities and a more substantial academic development community. Our thoughts and arguments on the nature of our work are framed within a discussion of professional identity, knowledge and academic freedom. 相似文献

This article aims to stimulate debate about the nature of field courses in higher education. We use a colloquium format that allows each of us to reflect on the philosophy of field course teaching and our writing endeavours to establish a dialogue between the authors and leave the reader with a sense of curiosity. It starts with a position paper that sets out a particular viewpoint on field courses to which responses were invited. Two of the respondents were experienced field-course teachers in disciplines traditionally associated with this type of curriculum, the other a lecturer in a non-field-course-oriented discipline. 相似文献

The main factors associated with technology integration have been the subject of research for over a decade. However, the conditions which sustain technological developments have been less frequently investigated. This paper explores this issue in the context of the use of videoconferencing in schools in England. The research took a multiple case-study approach by returning to schools with a reputation for demonstrating innovative policy and practice in videoconferencing, which were the subject of an earlier investigation. Analysis of developments in the interim five-year period led to the construction of a five-level typology of change. Further analysis identified critical dimensions associated with the sustainability of videoconferencing. These included technical and structural factors, as well as policy frameworks and personnel status. The perceived usefulness and relevance of videoconferencing as a learning technology emerges as a central determinant of sustainability, with the conclusion that for policymakers and schools, videoconferencing has become an ‘orphan’ technology. 相似文献

Abstract This article argues that because of the practice in the 1960s of placing black children in so-called ‘educational subnormal’ units there is now a reluctance to look at the speci?c needs of African Caribbean children. The post-Warnock politics of integration/inclusion following this period point to the ‘institutional racism’ of schools and white teachers to explain poor exam results. This article argues that in the current political climate which prioritizes ‘inclusion’ we should not patronize the black child. There is a need to position the factors of oppression equally with other factors of underachievement; to re-employ psychological, behavioural and educational tools as well as to deconstruct school processes and teacher attitudes; and to consider psychosocial factors related to underachievement without forgetting the reality of institutional racism. The article illustrates a research project that looks at the pastoral needs of African Caribbean children. It points to these needs as the key variable in unlocking their underachievement at school. 相似文献

This sub‐study is part of a longitudinal naturalistic investigation monitoring the social behaviour of young children (3‐8‐year‐olds) before and after the arrival of broadcast television in St Helena, South Atlantic. Children's free‐play behaviour in first school playgrounds was videotaped in 1994 (pre‐tv), and in 1995 and 1996 (post‐tv), and then coded and analysed by trained observers. Findings showed no significant differences in children's behaviour either across the availability of broadcast television (i.e. CNN) or with the addition of further channels (CNN plus others). 相似文献

In education, as in all other fields, grassroots practitioners need people with sharp, creative minds who are able to question accepted ideologies and challenge current practice. Such innovators stimulate argument and collaboration which, in turn, lead to the development of new philosophies and to more enlightened and effective practices. In this paper it Is argued that in special education, however, the philosophical models of integration which have been presented over the last eight years have often inadvertently inhibited, rather than promoted, the Introduction of more effective learning systems. 相似文献

In view of processes of individualization and pluralization, the requirements for living in modern societies result in significantly increased complexity of social constructions of reality. Especially for individualized juvenile people new forms of communities are a constitutive feature of social lifestyle progression and rearrangement. Within events a specific type of these juvenile communalities emerges. Based on two different cases, a music festival and an improvisational theater performance, this paper emphasizes a crucial similarity of events: the use of (physical) staging as a social mechanism for integration and distinction. The process of ‘eventization’ (i.e., spectacularization) provides a framework for action, in which emotional as well as mental affiliations constitute. 相似文献

This special issue comprises eleven articles from the DFG priority program “Competence Models for Assessing Individual Learning Outcomes and Evaluating Educational Processes”. The special issue aims at showing the priority program’s present state of discussion concerning essential concepts and questions related to the modeling of competencies. The first article describes the structure and research areas of the program and gives an overview on the current state of research. The short articles two to eleven discuss questions and problems which proved to be of particular importance during the work of the priority program in the last years. These articles constitute the result of a workshop of the participating scientists of the priority program in terms of position papers. 相似文献
