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

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

Wie können Ergebnisse der Kompetenzdiagnostik in Forschungsprojekten sinnvoll zurückgemeldet werden?
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

This article is focussing on a historical approach to the term of aesthetic education from three different angles: as history of ideas, biographies and images. Aesthetic education is thereby understood as performative and reflective involvement with aesthetics and the fine arts such as arts, theatre and literature etc. A first approach is defining the history of ideas as a theoretical reconstruction of aesthetic concepts and their educational relevance; this history is also discussing educational theories and their aesthetic implications. It is more or less an implicit and compensatory history because the important contexts are not visible at first sight; and the aesthetic and pedagogical theories often need a reciprocal addition. A biographical perspective is hereby concentrated on the biography of artists. Thereby the educational science of biographies are highlighting the situation of the arts and the artists, the development of becoming an artist, the progression as an artist and the artistic institutions in a educational-aesthetic nexus. Such a perspective is supplementing the history of ideas concerning cultural and socio-historical dimensions as well as institutional and biographic aspects. Finally, the history of images is focusing on the thesis that every picture also includes a programme of aesthetic education. In pictures the process of productive and reflective visualisation is expressed: paintings refer to their production and their understanding. For the method of the historical-educational iconography of aesthetic education a historicizing matrix from production aesthetics, work aesthetics and reception aesthetics is suggested. This matrix is combined with a theory of education as transformation of self-relation, of relations to other individuals and the world. The three approaches just mentioned are exemplified by Leonardo da Vinci and his famous picture “Vitruvian Man” from 1492. 相似文献

Higher educational institutions place a priority on the retention and timely graduation of students. Previous literature has identified transfer students to have unique concerns and that these concerns vary by major. While previous retention research has reported factors that influence students’ decision to remain in college, many of these studies treated transfer status as a homogenous group. The university in this study enrolls a high percentage of transfer students, and a large percentage of these transfers students enroll in Criminal Justice classes and become Criminal Justice majors. To determine if there are unique risk factors among Criminal Justice transfer students, this study uses multiple measures of transfer status to identify factors that might impact a students’ (1) university involvement, (2) GPA, (3) satisfaction with and sense of belonging to their university and (4) thereby influence their decision to remain in school. The proposition that transfer students as compared to native (nontransfer) students differ on how they face university challenges was also examined. While several variables were found to be important to students’ adjustment to the University, transfer status does not appear to be significant risk factor. Implications of the results are discussed. 相似文献

Over the past several decades, there has been a wealth of research identifying factors and conditions of persistence toward graduation for first-year students and more recently transfer students. While previous research recognizes these critical periods, some recent literature suggests that students may face a similar transitional period later in their academic careers as they advance into their major areas of study. To date, there has been a dearth of information exploring upper-level students' success and commitment to graduation. Exploring this later transition might provide a critical link to understanding the graduation gap between those students who persist to graduation and those who drop out. The purpose of this research was to review the intervention programs proscribed by the literature, design an intervention program, and examine the impact of the program on criminal justice students during this advanced transitional phase of their college careers. It examined the direct and indirect effects of the intervention program on both retention and the antecedents of successful retention while controlling for other relevant influences identified in the literature. The results indicated that the intervention had small, but significant positive direct and indirect effects on academic integration, commitment to the university, and graduating in a timely fashion. Policy implications are discussed. 相似文献

This investigation was designed to socially validate the characterization and operational definitions of collaboration as described in the professional literature and quantitatively identify salient features of collaboration. The study was conducted in two phases. The first phase employed an adelphi methodology asking practitioners to define and describe the collaborative process. Open-ended surveys were sent to teachers, special education teachers, administrators, and related service providers at the building, district, and state levels in 3 states representing distinct national regions. A content analysis team identified 35 thematic units that were used to create a second instrument for the second phase of the study, a factor analysis. Surveys were sent to teachers, special educators, administrators, and related service providers at the building, district, and state levels in 7 states. A factor analysis revealed 4 factors as salient components of collaboration. Results of the investigation socially validated most concepts of collaboration articulated in the literature. Overall, practitioners have a pragmatic view of the process of collaboration coupled with an emphasis on the collaborative ethic. Each identified factor is described and discussed. This article concludes with implications of these findings for professional preparation programs. 相似文献

Teacher education programs are being encouraged to collaborate with K‐12 partners to develop and implement contextually rich field experiences that integrate methods course instruction with public school practices. As a result, we outline four models of integrating methods instruction and field experiences and raise the question “How does the classroom and school context of the field experience influence what prospective teachers learned in the methods courses?” This study examines the way two different cohorts of prospective elementary teachers who learned to teach in two different contexts define their own social studies pedagogical content knowledge. The students' espoused philosophies of education offer insight into how different models of integrated field experiences may impact on their beliefs about social studies teaching. Through this study we raise questions that should be considered in constructing methods courses linked to field experiences and suggest Bronfenbrenner's model as a tool for looking at these contextual influences. 相似文献
