A growing body of literature is devoted to testing the reality of the “long-tail” phenomenon. This literature is mostly, if not exclusively, focused on the impact of Internet on the distribution of sales by product. However, the long tail also raises the issue of a possible change in the usual market structure of cultural industries: an oligopoly with a competitive fringe. To our knowledge, no paper addresses the following question: If the long-tail effect does exist, is it of more benefit to small or dominant publishers? The aim of this paper was to address this issue in the context of the French publishing industry. Our main findings are as follows: (1) the market concentration of the French book industry is lower online than offline and (2) the difference in concentration between the two channels of distribution tended to widen over the period 2004–2010. Strategies adopted by leading publishers on the Web do not allow them to maintain the market share obtained with bricks-and-mortar retailers. Furthermore, we show that the market share lost by dominant firms is captured by small publishers online and by medium-sized publishers in conventional stores. 相似文献

This study analyzed how clinically diagnosed women with eating disorders described the hurtful messages from parents, siblings, and peers that triggered eating disorder symptomology as well as the healing messages that assisted with coping and recovery. Three themes overlapping across all groups were revealed for hurtful messages: 1) critical, 2) social modeling, and 3) direct comparison. Our findings show that fathers, siblings, and peers similarly used teasing. Other points of distinction were uncovered for fathers: aggressive messages and denial of eating disorder. Competition with female siblings and friends was also a triggering factor for young females with eating disorders. Four distinct categories of healing messages were identified: 1) emotional, 2) instrumental, 3) informational, and 4) appraisal. Point of distinction for friends’ and siblings’ healing messages was absence of negative comments about weight and appearance. Results were able to encapsulate both helpful/supportive and hurtful/unsupportive messages, and these findings will be helpful for treatment centers who may incorporate them in recovery programs. 相似文献

Rainsford Island is an 11-acre island located in central Boston Harbor, Massachusetts. The proximity to the City of Boston resulted in the Island being used as a quarantine facility, poorhouse, veteran's hospital and school for wayward boys from 1737 to 1920. The Island consists of two linked topographic highs of glacial origin connected by a spit formed from reworked glacial material. The majority of the southern “high” is only slightly elevated above present-day sea level and was the site of a cemetery that serviced the quarantine facility, poorhouse and veteran's hospital. Historical research indicates that more than 1100 persons were buried on Rainsford during this time. The records for the cemetery have been lost through fire and only four sandstone posts presently mark the cemetery. Our team sought to (1) assess shoreline change on the southern portion of the Island; (2) map the boundaries of the unmarked cemetery using ground-penetrating radar and (3) determine the vulnerability of the cemetery to coastal erosion caused by long-term sea-level rise and episodic flooding. Shoreline change analysis indicates that the southern portion of the island has eroded on the north-facing beach at a rate of 0.2 m/yr while the south-facing beach has been stable. Topographic analysis of the landscape indicates that the central area of the southern portion is less than 1 m above sea level with a slightly elevated rim approximately 2 m above sea level. The ground-penetrating radar surveys indicated that the low-lying central portion exhibited evidence for burials. The results indicate that the cemetery is vulnerable to erosion and coastal flooding. A storm with a coastal storm surge of approximately 1 m will result in flooding of the cemetery. The northern edge of the cemetery is extremely vulnerable to erosion and the first mapped burial on the northern side will be impacted in approximately 10 years. The southern edge of the cemetery is protected by horizontal and vertical accretion. As a result, conservation resources should be concentrated on the northern edge of the cemetery. 相似文献

It is widely acknowledged that to be able to teach language and literacy with digital technologies, teachers need to engage in relevant professional learning. Existing formal models of professional learning are often criticised for being ineffective. In contrast, informal and self-initiated forms of learning have been recently recognised as meaningful and relevant but little is known about these authentic learning experiences for professional purposes. This article investigates three teachers’ self-initiated professional learning about digital technologies through their Personal Learning Networks. The analysis identified that the participants’ everyday digital literacy practices provided opportunities for a range of professional practices that supported learning about digital technologies: information retrieval and resources aggregation, cooperation, collaboration, reflections and socialising. It also revealed that the teachers considered this form of learning as valuable. The article concludes by discussing how knowledge about self-initiated professional learning might be used to draw out some implications for teachers’ professional development. 相似文献

The purpose of the study was to investigate the effects of revising goals focused on content and audience awareness on the
persuasive writing of fifth- and eighth-grade students. Students were randomly assigned to three different goal conditions:
a general goal; a goal to improve content; and a goal to improve content and communication with an audience. Final drafts
of essays were scored for elements of persuasive discourse relevant to content and audience and for overall persuasiveness.
Students in the audience goal group were more likely than both other groups to consider opposing positions and rebut them.
Students in both the content and audience goal groups wrote essays that were more persuasive than essays by students in the
general goal group. The results also indicate that eighth-grade students wrote more persuasively than fifth-grade students
and that girls wrote more persuasively than boys. 相似文献

The aim of this work is to analyze the dimensional structure of the Spanish version of the School and College Ability Test, employed in the process for the identification of students with high intellectual abilities. This test measures verbal and mathematical (or quantitative) abilities at three levels of difficulty: elementary (3rd, 4th, and 5th years in Primary school), intermediate (6th year in Primary school plus the 1st and 2nd years of Compulsory Secondary School or ESO), and advanced (3rd and 4th years of ESO plus the 1st and 2nd years of bachillerato – equivalent to High school). For each level there are two forms, X and Y. The research was undertaken with the results obtained from the application carried out for the validation and norming of the Spanish version of the test, and for which a representative sample of students from Navarre at these mentioned levels was taken. This study assessed the possible unidimensionality of the simplicity or the complexity of the structure of this test as an essential aspect of construct validity. To this end, the results were triangulated for the classic factorial techniques and non-parametric methods based on the item response theory. 相似文献
