Market Concentration Levels in the U.S. Consumer Book Industry: 1995–1996     

Albert N. Greco 《Journal of Cultural Economics》2000,24(4):321-336

While many scholars have studied the impact mergersand acquisitions have had on market concentrationlevels in various industries, few have addressed theconsumer book market, an important U.S. culturalindustry. This paper: (1) defines the consumer bookmarket; and (2) using consumer book mergers, salesdata, the U.S. Department of Justice's 1992 mergerguidelines, the Herfindahl–Hirschman Index, andfour-firm and eight-firm concentration ratios testswhether an illegal level of market concentration or aviolation of Justice's antitrust guidelines wereevident in 1995 and 1996. Data on market entrybarriers, outputs, and prices are also analyzed.  相似文献   

Adopting E-Readers with a Purpose: Surveying Users to Develop a Recreational Reading Kindle Lending Program     

Veronica Arellano Douglas  Conrad Helms 《College & Undergraduate Libraries》2015,22(1):76-89

Studies have shown that students and faculty have reservations about the performance and usability of e-readers in an academic setting. However, incorporating e-readers on college campuses for recreational reading purposes has proven to be quite popular. These trends held true in a study conducted by librarians at St. Mary's College of Maryland. Students, faculty, and staff were surveyed on their use of and familiarity with e-books, e-readers, and tablet devices with e-reader functionality. Information gathered from this survey resulted in the launch of a pilot Kindle lending program focused exclusively on promoting recreational reading.  相似文献   

Guided reading: young pupils' perspectives on classroom practice     

Veronica Hanke 《Literacy》2014,48(3):136-143

Guided reading is widely perceived to be tricky in English primary schools; prior research has found difficulties with teacher interpretation and implementation. The study reported here suggests that to understand the problems associated with it we should also take into account pupils' perspectives on their guided reading lessons. In this case, the pupils were 4–7 years old. The special challenges of accessing young pupil perspectives were addressed through co‐authored drawings, a type of graphic elicitation. The drawings, together with other collected data, generated insights into pupil perceptions of literacy practices, of the role of friends and ability grouping in learning to read, and of their teachers' organisational challenges. A socio‐cultural analysis of these data indicates that these pupils were sensitive to the social and cultural contexts of their guided reading lessons. It may be that precise official advice for guided reading in England, originating in the National Literacy Strategy documents in 1999 and the Primary National Strategy documents in 2003 and 2008, has been insufficiently sensitive to the complex teaching and learning contexts of guided reading and that this discrepancy has contributed to the identified difficulties. The paper concludes that some rethinking of the literacy practice of guided reading would be valuable.  相似文献

Three-dimensional modelling of statues: the Minerva of Arezzo     

Raffaella Fontana  Marinella Greco  Marzia Materazzi  Enrico Pampaloni  Luca Pezzati  Claudio Rocchini  Roberto Scopigno 《Journal of Cultural Heritage》2002,3(4):1

The Minerva of Arezzo is an ancient bronze statue located at the Museo Archeologico in Florence and currently under repair at the Restoration Centre of the Soprintendenza Archeologica of the Tuscany Region. We assembled a complete three-dimensional (3D) digital model of the Minerva before the restoration started. More 3D models will be produced to keep track of the variations that occurred during the restoration process, up to the final acquisition of the form of the restored artwork. The modelling of the Minerva will be the focal point of an ambitious “Minerva Project” that involves the integration of data from other sources in a 3D digital model of the object. Besides this, the project is aimed at showing how 3D techniques can be used to design useful and easily manageable new tools for the diagnostics of archaeological objects. 3D measurements have been realized by means of a high-resolution laser scanner developed at National Institute for Applied Optics (INOA). The instrument is composed of commercial low-cost components in order to be competitive with the very expensive commercial devices. Besides this, our scanner is supported by an efficient and flexible software developed by Consiglio Nazionale delle Ricerche (CNR) that supports all the post-processing phases of a 3D scanning session (range data alignment, merge and simplification).  相似文献

Attitudes and aspirations regarding engineering among Chinese secondary school students: comparisons between industrialising and post-industrial geo-engineering regions of Mainland China and Hong Kong     

Peter Kutnick  Zhiyong Zhu  Cecilia Chan  Rosanna Yuen-Yan Chan  Betty Pok-Yee Lee  Veronica Ka Wai Lai 《Compare》2018,48(4):608-629

School-based pipelines/routes for university and technical engineering education are recognised as important for economic development and the high-school years are critical for shaping students’ career aspirations and attitudes. This study examined a range of attitudes/experiences on the aspirations of secondary students to pursue engineering education and vocation. Experiential/attitudinal aspects covered demographic characteristics, family/school support, practical learning experiences, curricular/extra-curricular experiences, attitudes, perceptions and engineering-efficacy that may affect aspirations. A validated questionnaire capturing these variables was administered to respective samples of secondary school students from four Chinese geo-engineering regions (Beijing, Guangzhou, Hong Kong and ShanXi; 5965 students) that represent differing degrees of industrialisation. Comparative analyses across regions show ‘doing’ engineering is key to motivating students’ aspirations; while regional variations suggest that schooling and family factors are generally more significant in industrialising Mainland cities, and extracurricular opportunities and personal factors are more significant for students in post-industrial Hong Kong.  相似文献   

Evaluation criteria for competency-based syllabi: a Chilean case study applying mixed methods     

Oscar Jerez  Leslier Valenzuela  Veronica Pizarro  Beatriz Hasbun  Gabriela Valenzuela  Cesar Orsini 《Teachers and Teaching》2016,22(4):519-534

In recent decades, higher education institutions worldwide have been moving from knowledge-based to competence-based curricula. One of the greatest challenges in this transition is the difficulty in changing the knowledge-oriented practices of teachers. This study evaluates the consistency between syllabus design and the requirements imposed by a competence-based learning environment. To make this comparison, the study sets four criteria (C1: explicit relationship between syllabus and graduate profile; C2: precision of the learning outcomes and assessment criteria; C3: contents that mobilise the learning outcomes; and C4: learning and assessment activities) derived from the literature and a thematic analysis of competence-based learning in higher education. Afterwards, a sample of 150 syllabi from different disciplines of five Chilean public universities were analysed, all of which stated the use of learning outcomes and competences in their learning models. Using a three-point Likert scale derived from the aforementioned criteria and their indicators, a comparison was made between the actual practices reflected in the syllabus design and the previously established criteria. Results show a gap between the declaration of a competency-based curriculum and actual syllabus outlines. Moreover, there are important differences among disciplines. Although all disciplines present high levels of accomplishment for Criteria 1 and 3, only the discipline of health sciences presents an acceptable level for Criteria 2 and 4. It is recommended that further research be undertaken towards identifying effective competency-based syllabus design.  相似文献   

Market-level information and the diffusion of competing technologies: An exploratory analysis of the LAN industry     

Vasilis Theoharakis  Demetrios Vakratsas  Veronica Wong 《Research Policy》2007,36(5):742-757

Market-level information diffused by print media may contribute to the legitimation of an emerging technology and thus influence the diffusion of competing technological standards. After analyzing more than 10,000 trade media abstracts from the Local Area Networks (LAN) industry published between 1981 and 2000, we found the presence of differential effects on the adoption of competing standards by two market-level information types: technology and product availability. The significance of these effects depends on the technology's order of entry and suggests that high-tech product managers should make strategic use of market-level information by appropriately focusing the content of their communications.  相似文献
