Effectiveness of additional representations for the search result presentation on the web

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.     

我国图情档学科关于文化信息数字资源整合的研究——以博物馆研究为视角

我国图情档学科认为博物馆是文化信息数字资源整合的主体之一。博物馆中以其展品为代表的文化信息资源对满足公众多样化的文化需求、增强中华文化竞争力起着重要作用。本文借助Citespace分析软件,通过对作者、机构、关键词可视化图谱的绘制,识别出我国图情档学科下以博物馆为主题词的科研文献成果概况、科研机构分布及研究热点词与其研究发展趋势。经分析得知,该学科下以博物馆为主题的研究可以分为两个阶段:第一阶段(1996-2008年)主要是博物馆文献资源的开发与利用、博物馆与图书馆文献资源的开发与利用、博物馆古籍保护管理工作以及古籍文献等主题。第二阶段(2009-2019年)主要探讨三馆馆际合作的资源整合路径、数字资源整合理论模式与合作机制等的研究,并结合相关文献内容,深入探讨以博物馆为主题的研究重点,基于此,我国图情档学科应以博物馆中丰富多样的文化信息资源为视角,开展涵盖档案馆、图书馆、博物馆的全种类、全范围的全文化信息数字资源整合。最后,本文围绕数字资源整合这一具有影响力的研究热点,探讨如何从图情档学科的角度出发,有效地涵盖博物馆,构建以图书馆、档案馆、博物馆三馆为主体的数字资源整合模式与机制,建立为公众文化精神需求服务的信息共享平台。     

Fitness,physical activity and academic achievement in overweight/obese children

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.     

Hacia un lenguaje gráfico en la enseñanza

En este trabajo se parte del supuesto de que el uso de recursos gráficos, además de ser positivo, está creciendo continuamente en la enseñanza. Con el fin de facilitar la utilización de recursos gráficos en la realización de transparencias, mapas mentales, mapas conceptuales, resúmenes, etc., se proponen unas reglas básicas que constituyen en sí mismas un lenguaje gráfico     

Special education reform in Brazil: an historical analysis of educational policies

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.
