This essay examines the historical construction of the Hispanic audience and analyzes how contemporary Hispanic audience researchers/marketers have disrupted that unitary, essentialist construction by segmenting the Hispanic audience by class. The principal tool in this effort is language: the Spanish language is proxy for the “mass” of lower socioeconomic class Hispanic audience; English language usage by Hispanics is the sign of a higher class of Hispanic audience. The clearly defined panethnic conceptualization of the Hispanic audience, the nexus of which is the Spanish language, has been blurred. The study draws on interviews with Hispanic media marketers and audience researchers and on analysis of Hispanic market research reports.  相似文献

PurposeOne of the aims of library catalogs is to clearly represent the relationships existing between two or more bibliographic entities, enabling users to make sense of these relationships. Educational bibliographic relationships are the relationships between an educational work, such as a textbook, and its related works. The main interest of this study was to understand the nature of the supplementary work-to-work bibliographic relationships among educational works and the constitution of educational bibliographic families in the Canadian context using AMICUS (the Canadian national catalog). A thorough understanding of educational bibliographic relationships is required for understanding the Functional Requirements for Bibliographic Records (FRBR) supplementary relationships.Design/methodology/approachWe studied the extent and size of educational bibliographic relationships in the bibliographic universe found in the AMICUS catalog. This is an empirical investigation into the nature and extent of educational work-to-work bibliographic relationships by examining title of works, notes and added entries in bibliographic records. The study was carried out between September 1st 2010 and December 22nd 2010 and examines educational bibliographic relationships between Canadian 2009 publications in each class of the Dewey Decimal Classification (DDC). In other words, this study poses two main questions: What is the structure of educational supplementary bibliographic relationships in Canadian publications? Do significant differences exist across the ten DDC classes?FindingsResults show that 595 works of the 2009 bibliographic records in the AMICUS catalog contain an educational supplementary bibliographic relationship. Of the Canadian publications with an educational supplementary work-to-work bibliographic relationship that were studied, the rates of educational bibliographic relationships were relatively high in the fields of Science (27%), Technology (22%), Social Sciences (20%), and Language (19%). The results of this study suggest a set of guidelines for the establishment and maintenance of educational bibliographic relationships.Originality/valueThis is the first research to examine the educational bibliographic relationships, as supplementary relationships.  相似文献

Like other recent library management systems, OCLC's WorldShare Management Services (WMS) is cloud-based. But unlike the others, WMS opens WorldCat for applications beyond its traditional role as a source of bibliographic records. It enables catalogers to work directly from the Master Record, which no longer needs to be exported to a local system. This article describes the impact of WMS on the roles and functions of cataloging departments, and asks if it is changing the meaning of cataloging. It concludes that while the workflows are changed dramatically, the profession of cataloging remains relevant.  相似文献

ABSTRACT

This study used citation analysis in conjunction with a subjective rubric with five validated criteria to assess the quality of a purposive sample of 452 education dissertation reference lists produced at a nontraditional institution from six doctoral programs. These programs used a variety of distance education models. The citations were then compared with the 100 reference lists selected from doctoral education programs at 10 traditional institutions. Criteria included the breadth of resources, depth of the literature review as shown through the citing of critical historical and theoretical works, depth as demonstrated through the scholarliness of citations chosen, currency, and relevancy. The study discusses how the expanded sample of traditional reference lists continued to demonstrate consistent patterns. In contrast, although the sample of reference lists from distance education programs was much expanded, the patterns of the subsets of reference lists at the nontraditional institution were significantly diverse. The patterns of 35 doctoral reference lists from another for-profit, nontraditional institution known for providing distance education were also examined to compare the results of the two nontraditional programs. Possible reasons for differences in citation patterns by traditional and nontraditional programs are discussed, and the possible role of distance education and program criteria are examined for insights they offer into the use of citation analysis as an assessment tool of the library research skills of doctoral students.  相似文献

ABSTRACT

Carrying out effective and efficient research on Mexican law presents special challenges. Some of these are structural because they condition the entire research process. This guide covers all aspects of Mexican legal research, providing a contextualized overview of the subject. The guide is organized into three main sections: Primary Sources, Secondary Sources, and Online Resources. The reader of this guide will gain a solid foundation in how to do research on Mexican law.  相似文献

ABSTRACT

Mechanical properties of aged beeswax were studied by an indirect measurement, using hydrogenated beeswax as a model material. The adequacy of the model was evaluated by comparison of its chemical composition and thermal properties with those of samples of historical beeswax. It was found that the gradual decrease in content of unsaturated compounds in beeswax contributes significantly to changes of its mechanical properties. As a consequence, beeswax artefacts become increasingly prone to mechanical damage during natural ageing. Understanding the difference between mechanical properties of recent and historical beeswax is primarily important from the point of view of safe handling and storage of such artefacts. Besides, this knowledge could help conservation scientists, e. g. when preparing model samples for testing new conservation methods.  相似文献

Summary

The cause of yellowing of oil-based paints has been investigated by analysing drying oils simultaneously by iodometry (to determine the degree of oxidation) and by colorimetry. It was found that yellowing of drying oils can be attributed to co-oxidation reactions of contaminants. Yellowing level is closely related to the extent of drying and appears to be unaffected by increase in temperature, the addition of driers, or linolenate content.  相似文献

This article examines how routine and ostensibly rational administrative and medical procedures required of asthmatic Medicaid patients to gain treatment under a managed care health delivery system, in fact, further disenfranchise them.  相似文献

International University Education: An Australian Perspective   总被引:1,自引:1,他引:0  
This paper attempts to explore the effectiveness of UK universities' websites. The area of branding in higher education has received increasing academic investigation, but little work has researched how universities demonstrate their brand promises through their websites. The quest to differentiate through branding can be challenging in the university context, however. It is argued that those institutions that have a strong distinctive image will be in a better position to face a changing future. Employing a multistage methodology, the web pages of 20 UK universities were investigated by using a combination of content and multivariable analysis. Results indicated ‘traditional values’ such as teaching and research were often well communicated in terms of online brand but ‘emotional values’ like social responsibility and the universities' environments were less consistently communicated, despite their increased topicality. It is therefore suggested that emotional values may offer a basis for possible future online differentiation.  相似文献

This paper asks whether the integrated training provision currently offered through the different Spanish Second Chance Programmes (SCPs) constitutes a valid response to the educational needs and deficits known to exist among those young people who do not satisfactorily complete the Compulsory Secondary Education stage (ESO). The objectives of the current Social Guarantee Programmes (SGPs) are examined, as are the characteristics of the young people who participate in them. The Programmes of Initial Vocational Qualification (PCPI) envisaged in the most recent educational legislation are also discussed. Having identified the key factors which the empirical studies suggest influence the effectiveness of these programmes in addressing the educational needs and training deficiencies of the young people involved, a number of proposals are presented in connection with the training needs of teaching staff. The paper concludes with a number of proposals for improving the educational response to the challenges that the new perspectives and expectations raise for the development of a system of inclusive education to overcome the education deficits of the young people concerned.  相似文献
