The rising number of data portals has been increasing demand for new techniques to assess data openness in an automated manner. Some methods have emerged that presuppose well-organized data catalogs, the availability of API interfaces and natively exposed metadata. However, many data portals, particularly those of local governments, appear to be misimplemented and developed with the classic website model in mind, which provides access to data only through user interaction with web forms. Data in such portals resides in the hidden part of the web, as it is dynamically produced only in response to direct requests. This paper proposes an automated method for assessing government-related data in the deep web on the basis of compliance with open data principles and requirements. To validate our method, we apply it in an experiment using the government websites of the 27 Brazilian capitals. The method is fully carried out for 22 of the capitals' websites, resulting in the analysis of 5.6 million government web pages. The results indicate that the keyword search approach utilized in the method, along with the checking of web pages for multifield web forms, is effective for identifying deep web data sources, as 1.5% of web pages with potential government data that are analyzed are found to contain data stored in the deep web. This work contributes to the development of a novel method that allows for the continuous checking and identification of government data from surface web data portals. In addition, this method can be scaled and repeated to assure the widest possible content coverage.  相似文献   

Teaching and learning conceptions in Engineering Education: an innovative approach on Mathematics     

Mario Neto Borges  Maria Do Carmo Narciso Silva Goncalves  Flavio Macedo Cunha 《European Journal of Engineering Education》2003,28(4):523-534

A worldwide problem in Engineering education is the high rates of students' failure and drop out particularly at the beginning of the course. This is related to the process by which students learn Mathematics. An innovative methodology of teaching calculus was developed and it is presented in this paper. The approach, based on both course modularisation and the error theory, is student centred. It fosters student/lecturer commitment and emphasizes continuous assessment of the process. Knowledge, in this work, is regarded as a construction and reconstruction process based on phenomenological and hermeneutic concepts. Survey results demonstrated the effectiveness of the applied methodology.  相似文献

Effects of distinct practice conditions on the learning of the o soto gari throwing technique of judo     

Fábio Rodrigo Ferreira Gomes  Flavio Henrique Bastos  Cássio de Miranda Meira Jr.  Jaqueline Freitas de Oliveira Neiva  Go Tani 《Journal of sports sciences》2017,35(6):572-578

The aim of this study was to investigate the effects of different types of practice on learning the o soto gari, focusing on the kuzushi (unbalancing the opponent). A total of 64 children (mean age 9.19 ± 1.41 years) were assigned to one of four groups: (1) static traditional practice, i.e., uchikomi – repetition of the moving pattern that characterises the technique up to the point of throwing; (2) in motion traditional practice – uchikomi with the tori (player executing the technique) moving/walking; (3) whole practice with pre-kuzushi – full technique with a preparatory component for kuzushi; (4) progressive parts practice with pre-kuzushi – progressively introducing kuzushi, tsukuri (set-up to execute the technique) and kake (final part of the technique; projection) with pre-kuzushi. Pre-test, acquisition, post-test and retention test were carried out. Movements were video recorded and analysed regarding three aspects: global technique of the tori, occurrence of a movement pattern performed by the tori to unbalance the uke (player receiving the “attack”), and occurrence of actual unbalance (kuzushi). Results showed no significant differences between-groups. However, different within-groups improvements suggest that using a uchikomi with pre-kuzushi can help learners deal with the motor actions of pulling and pushing in order to unbalance the opponent.  相似文献   

Diagnosis of pathologies in ancient (seventeenth-eighteenth centuries) decorative blue-and-white ceramic tiles: Green stains in the glazes of a panel depicting Lisbon prior to the 1755 earthquake     

Teresa P. Silva  Maria-Ondina Figueiredo  Maria-Alexandra Barreiros  Maria-Isabel Prudêncio 《文物保护研究》2014,59(2):63-68

Decorative panels of ceramic glazed tiles comprise a valuable cultural heritage in Mediterranean countries. Their preservation requires the development of a systematic scientific approach. Exposure to an open-air environment allows for a large span of deterioration effects. Successfully overcoming these effects demands a careful identification of involved degradation processes. Among these, the development of micro-organisms and concomitant glaze surface staining is a very common effect observed in panels manufactured centuries ago. This paper describes a study on the nature of green stains appearing at the surface of blue-and-white tile glazes from a large decorative panel with more than one thousand tiles, called Vista de Lisboa that depicts the city before the destruction caused by the 1755 earthquake. The characterization of green-stained blue-and-white tile glazes was performed using non-destructive X-ray techniques (diffraction and fluorescence spectrometry) by directly irradiating the surface of small tile fragments, complemented by a destructive scanning electron microscopy (SEM) observation of one fragment. Despite the green staining, analytical X-ray data showed that no deterioration had occurred irrespective of the blue or white color, while complementary SEM-EDX data provided chemical evidence of microorganism colonization at the stained glaze surface.  相似文献   

Information as a Tool for Development     

Nice Figueiredo 《International Information and Library Review》2013,45(3):189-201

Abstract

Argument surrounds the concept that information can only be a tool for development if it is useful for the intended users. A short discussion on information value is presented with a brief summary of the main findings of users’ studies and collections evaluations. These are considered as the basic requirement for the establishment of services/products useful for the target users. A case study describing the implementation of networks of information in Brazil is used to support the argument.  相似文献   

Quantity of Group Child Care,Behavior Problems,and Prosocial Behaviors: A Study with Portuguese Preschoolers     

Nuno Torres  António J. Santos  Ligia Monteiro  Mafalda Figueiredo  Brian E. Vaughn 《Early education and development》2013,24(8):1145-1165

Research Findings: Data from a national sample of Portuguese preschool centers were used to examine the relationship between age of start and number of hours in child care and levels of externalizing and prosocial behaviors with peers. Participants were both parents and teachers of 543 children (mean age = 4.5 years, 50.6% girls). Children started child care between 3 and 64 months and were attending child care 1–9 hr per day. The child care centers’ classrooms had adult–child ratios between 5 and 8.7 and group sizes between 15 and 26 children. Externalizing and prosocial behavior with peers was assessed with the Social Competence and Behavior Evaluation Scale–Short Form completed by the 3 adult informants. Control variables included family sociodemographics and education level, maternal parenting style assessed with the Parenting Styles and Dimensions Questionnaire, and maternal stress assessed with the Parenting Experiences questionnaire. Practice or Policy: Both the number of hours per week in child care and an earlier start of center-based child care had modest but significant associations with dimensional scores from teachers’ reports of externalizing behavior but not with mothers’ or fathers’ reports, suggesting that externalizing behavior with peers could be regarded as context specific to peer relationships in group child care. There was no evidence that the quantity of exposure to child care per se could be a substantial risk factor for severe levels of externalizing behavior. Prosocial behavior with peers was not significantly associated with the number of hours in child care or with the age of entry into group child care.  相似文献

Between the prescribed and the lived in physical education lessons     

Zenólia Christina Campos Figueiredo  Janaína Esfalsini Figueira  Sandra Soares Della Fonte  Francisco Eduardo Caparróz 《Sport, Education and Society》2016,21(6):945-962

This study examines physical education (PE) curriculum development in an elementary school. Our goal was to understand the daily construction of a curriculum. We sought to analyse the theoretical and methodological framework and documents that a PE teacher uses each day while putting a curriculum into practice (lived curriculum). The data collection instruments included participant observation, interviews and document analysis. The analytical process revealed the influence of internal and external factors that affect both the authorship and the autonomy of a teacher working on the daily construction of a lived PE curriculum and that create tensions, struggles and conflicts.  相似文献
