For traditional industries it is a real challenge, not only to achieve a clear product differentiation, but also to provide adequate services in order to ensure value and customer fidelity.  相似文献

The presentation of search results on the web has been dominated by the textual form of document representation. On the other hand, the document’s visual aspects such as the layout, colour scheme, or presence of images have been studied in a limited context with regard to their effectiveness of search result presentation. This article presents a comparative evaluation of textual and visual forms of document representation as additional components of document surrogates. A total of 24 people were recruited for our task-based user study. The experimental results suggest that an increased level of document representation available in the search results can facilitate users’ interaction with a search interface. The results also suggest that the two forms of additional representations are likely beneficial to users’ information searching process in different contexts.  相似文献

ABSTRACT

The aim of this study was to examine the associations of fitness and physical activity with academic achievement in children with overweight/obesity. A total of 106 (10.0 ± 1.1y, 61 boys) children participated. The fitness components were assessed by field and laboratory-based tests. Physical activity was measured via accelerometry. The academic achievement was assessed by a standardised test and school-grades. Field-based cardiorespiratory fitness was associated with language skills (ß-standardised- ranging from 0.281 to 0.365, p < 0.01). The field-based muscular strength was associated with grade point average, natural and social sciences, and foreign language (ß = 0.280–0.326, all p ≤ 0.01). Speed-agility was associated with some language-related skills (ß = 0.325–0.393, all p ≤ 0.01). The laboratory-based muscular strength also showed an association with mathematics skills (ß = 0.251–0.306, all p ≤ 0.01). Physical activity did not show significant association with academic achievement (p > 0.01). Overall, the significant associations observed for muscular strength and speed/agility were attenuated and disappeared in many cases after additional adjustments for body mass index and cardiorespiratory fitness, indicating that these associations are inter-dependent. Our study contributes by indicating that other fitness components apart from cardiorespiratory fitness, such as muscular strength and speed-agility, are positively associated with academic achievement. However, these associations appear to be dependent on body mass index and cardiorespiratory fitness.  相似文献

News use and political discussion are often studied as important factors in understanding the effects of political efficacy on participation. However, measurements of external efficacy often blur distinctions between personal ability and government responsiveness. This study establishes a measure for perceptions of competence in the institutions of democratic government—government efficacy (GE). Drawing on panel survey data from the United States, confirmatory factor analysis introduces GE as a unique construct. Political efficacy dimensions are tested for their impact on news consumption, discussion, and political participation. Results add to the extant literature revolving the role of political efficacy on news use, discussion, and participation.  相似文献

The “Digital Heritage: Spotlight on Europe” column examines technological advances internal and external to cultural institutions. The digital shift changed radically how cultural heritage is made, disseminated, distributed, accessed, consumed, and monetized. One of the most important revolutions is that the user's role changed dramatically, shifting from passive observers to active participants and content producers with many new and exciting opportunities for engagement, creative use, and access. The strength of the column is its broad, international focus, and contributors are encouraged to explore issues and recent advances in digital heritage theories, methodologies, standards relevant to the European region, as well as the larger, global audience. Interested authors are invited to submit proposals and articles to the column editor at annamaria.tammaro@unipr.it. Please include “ILLR submission” in the subject line of the e-mail.  相似文献

ABSTRACT

This paper describes an histprical view of the legal and political aspects related to special education. It analyses the current and future perspectives that public and private educational institutions utilize to provide school services to individuals with disabilities in Brazil. Although Brazil has developed laws and provisions to guarantee the integration of students with disabilities into regular schools, this is not happening in most cases. In fact, Brazil does not yet have schools that consider the diversification of students’ capabilities as beneficial to the intellectual development of deficient and non‐deficient students. Poor teacher training and institutional conservatism constitute the obstacles to the implementation of innovation in this area. Most of the innovations seen today are the fruit of individual initiatives, such as the Project for Training Teachers to Integrate the Disabled into Schools (PROEDEM) and the Project for Using Computers in Special Education, that we describe. We believe that these new proposals will have a great impact on the education of students with deficiencies. This will raise the consciousness of educators and will help to transform the current conceptions and actions related to the education of people with disabilities, making possible the implementation of special education reforms.  相似文献
