Business opportunities in international markets are largely determined by accessibility, transparency, and legal frameworks fair to all parties concerned. Arab book markets in principle offer a tremendous potential with more than 300 million readers sharing one common language. Besides unsolved censorship issues, problems with money collection, and differing regulations, however, the lack of a uniform book distribution system is the most critical hurdle for the development of a common Arabic book market. Most importantly, there is no comprehensive database containing accurate content briefs, background information on authors, ISBN numbers, and publisher company information as well as all relevant commercial data such as book prices, weight, logistics terms, and availability. Authors and publishers are hard hit as they often need to organize book transportation, delivery, and invoice collection on their own. At present, “selling book fairs” in the Arab world—with the exception of Abu Dhabi International Book Fair—present themselves as crowded book bazaars rather than executive meeting points. The authors of the article, however, are anticipating change: New distribution initiatives will soon interlink regional Arabic markets and create unique growth and profit opportunities.  相似文献

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

This paper explores the emotional responses that assignment feedback can provoke in first-year undergraduates. The literature on the link between emotions and learning is well established, but surprisingly research on the relationship between emotions and feedback is still relatively scarce. This article aims to make an additional contribution to this emerging field. Semi-structured interviews with 24 first-year undergraduate students from the Humanities and Social Sciences department in a post-1992 institution were conducted. The interview narratives identified how the emotional impact of feedback was related to: prior experiences of education, the significance participants attached to the feedback received on their first assignment and how their interpretations of feedback comments were linked to beliefs about themselves as learners. The implications of these experiences on student ‘belonging’ and learning are discussed. The underlying themes that emerged from the findings are the polarised emotions of anxiety and confidence. Based on the findings, the paper concludes by making recommendations for reconceptualising feedback on first-year assignments. It suggests that a holistic assessment approach, which incorporates timely feedback indicating if students are ‘on the right lines’ with low-stakes assignments, is a practice that may both reduce anxiety and increase confidence to support students.  相似文献

Transfer research examines how artistic activities can have an impact outside of the realm of art itself. The article concludes that this research can be carried out in a meaningful way, only within the framework of a comprehensive theory of aesthetic education. This theory would encompass the structural analysis of artistic activity, as well as biographical reports about artistic experiences. The elucidation of the concepts or themes relevant to the theory would include the notion of aesthetic experience, the understanding of immediate, aesthetic experiences, the analysis of artistic processes, and the outcomes of scientifically evaluated applications of aesthetic education.  相似文献

This paper addresses potential negative effects of systematic external competence assessment on different levels of the education system. We discuss possible sources of misinterpretations of competence assessment feedback, potential consequences of feedback and assessment for different education stakeholders (teachers, students, and educational administration) as well as negative effects of systematic competence assessment on the culture of teaching and learning. The paper concludes with some reflections on possibilities to prevent or reduce the discussed negative effects.  相似文献

Reporting on research results to students, teachers and institutions is a big challenge within competence assessment research: students individually have to be given feedback about how they performed, teachers have to be provided with information about their classes, education authorities are interested in actual research results. For feedback being helpful for students, teachers and institutions, the following questions have to be thought of: (1) Who is the feedback given to? What is the aim of the feedback? (2) Which results shall be reported? (3) How should feedback theoretically look like? And (4) how does feedback depend on the given general framework? The given article discusses these questions and offers a “checklist” to research projects with a focus on competence assessment.  相似文献
