Various authors have highlighted the potential contribution of the internet to enhance the interactivity, transparency, and openness of public sector entities and to promote new forms of accountability. The search for new styles of governance which promote higher levels of transparency and the engagement of citizens is viewed as a way of improving citizens' trust in governments. As the social media are becoming ubiquitous, both academics and practitioners need some initial and reliable background data about the deployment of this kind of technology at all levels. The aim of this work is to provide an overall view about the use of Web 2.0 and social media tools in EU local governments in order to determine whether local governments are using these technologies to increase transparency and e-participation, opening a real corporate dialog. In addition, the paper tries to identify which factors promote the level of development of these tools at local level. Our results show that most local governments are using Web 2.0 and social media tools to enhance transparency but, in general, the concept of corporate dialog and the use of Web 2.0 to promote e-participation are still in their infancy at the local level. 相似文献

There is a wide set of evaluation metrics available to compare the quality of text clustering algorithms. In this article,
we define a few intuitive formal constraints on such metrics which shed light on which aspects of the quality of a clustering
are captured by different metric families. These formal constraints are validated in an experiment involving human assessments,
and compared with other constraints proposed in the literature. Our analysis of a wide range of metrics shows that only BCubed satisfies all formal constraints. We also extend the analysis to the problem of overlapping clustering, where items can simultaneously
belong to more than one cluster. As Bcubed cannot be directly applied to this task, we propose a modified version of Bcubed
that avoids the problems found with other metrics.

Personalization can be addressed by adaptability and adaptivity, which have different advantages and disadvantages. This study investigates how digital library (DL) users react to these two techniques. More specifically, we develop a personalized DL to suit the needs of different cognitive styles based on the findings of our previous work [Frias-Martinez, E., Chen, S. Y., & Liu, X. (2008) Investigation of behavior and perception of digital library users: A cognitive style perspective. International Journal of Information Management]. The personalized DL includes two versions: adaptive version and adaptable version. The results showed that users not only performed better in the adaptive version, but also they perceived more positively to the adaptive version. In addition, cognitive styles have great effects on users’ responses to adaptability and adaptivity. These results provide guidance for designers to select suitable techniques to develop personalized DLs. 相似文献

In the rural Andes of Peru, primary school inefficiency ranks higher than in the rest of the country, with a nearly 50 per cent rate of first grade repetition. In 1993 the investigators administered a battery of four psycho-educational tests to 360 schoolchildren in the fourth and fifth grades at ten primary schools in the Andean region of Huaraz. They also recorded the children''s individual characteristics, i.e. family background, nutritional status, and educational attainment, and rated the schools according to educational features such as classroom size, time devoted to learning, and student-teacher ratio. A year later, in 1994, children were re-examined in the schools using the same test battery. All subjects were small for their age, had poor diets, spoke mostly Quechua at home (Spanish in school), lived in a rural environment, and walked considerable distances to school. Regression analyses of the 1993 data indicated that the performance of Quechua children on verbal tests was heavily influenced by family background, while their mathematical competence was related to school experience. On the other hand, improvement in test scores from one year to the next appeared to be strongly related to test performance in 1993 and less clearly to the other recorded variables. Finally, the schools'' promotion rates were clearly associated with test scores from the previous year but less clearly with grade repetition rates. 相似文献

Google Scholar,Web of Science,and Scopus: A systematic comparison of citations in 252 subject categories 总被引:1,自引:0,他引:1

Despite citation counts from Google Scholar (GS), Web of Science (WoS), and Scopus being widely consulted by researchers and sometimes used in research evaluations, there is no recent or systematic evidence about the differences between them. In response, this paper investigates 2,448,055 citations to 2299 English-language highly-cited documents from 252 GS subject categories published in 2006, comparing GS, the WoS Core Collection, and Scopus. GS consistently found the largest percentage of citations across all areas (93%–96%), far ahead of Scopus (35%–77%) and WoS (27%–73%). GS found nearly all the WoS (95%) and Scopus (92%) citations. Most citations found only by GS were from non-journal sources (48%–65%), including theses, books, conference papers, and unpublished materials. Many were non-English (19%–38%), and they tended to be much less cited than citing sources that were also in Scopus or WoS. Despite the many unique GS citing sources, Spearman correlations between citation counts in GS and WoS or Scopus are high (0.78-0.99). They are lower in the Humanities, and lower between GS and WoS than between GS and Scopus. The results suggest that in all areas GS citation data is essentially a superset of WoS and Scopus, with substantial extra coverage. 相似文献

OBJECTIVE: This study aimed to explore the relationship between perceived neighborhood social disorder and attitudes toward reporting child physical abuse. METHOD: Data from a national probabilistic sample (N=9,759) were used. Responses about the perception of neighborhood social disorder, perceived frequency of child physical abuse in Spanish families, and willingness to report a case of child physical abuse to the police were collected through face-to-face interviews in respondents' homes. RESULTS: Multivariate logistic regression analysis showed that perceived neighborhood social disorder was negatively related to residents' attitudes toward reporting child physical abuse. These results take into account the potential confounding effects of gender, age, socio-economic status, educational level, size of city, and perceived frequency of child physical abuse on reporting attitudes. CONCLUSION: Results illustrate the important role that community characteristics may play in processes relevant to the prevention of child maltreatment such as residents' attitudes towards reporting child physical abuse, and suggest that especially disadvantaged communities characterized by high levels of social disorder need to be specifically targeted if the aim is to increase the capacity to prevent child maltreatment in the community. 相似文献

We take advantage of a combinatorial misconception and the famous paradox of the Chevalier de Méré to present the multiplication rule for independent events; the principle of inclusion and exclusion in the presence of disjoint events; the median of a discrete-type random variable, and a confidence interval for a large sample. Moreover, we pay tribute to our original bibliographic sources by providing two computational tools to facilitate the students' insights on these topics. 相似文献

Scientific research and student involvement are critical to the formation of physicians, yet the number of medical researchers has decreased over time. To implement corrective strategies, the variables associated with positive research attitudes and productivity among medical students must be identified. The aim of this study was to evaluate the variables associated with students interested or involved in research. A validated questionnaire was applied to the student members of an established anatomy research group in a Mexican medical school with a six-year medical program. Data were collected and analyzed. A total of 85.5% (n = 77/90) students answered the survey with most respondents being second-year medical students. The majority of respondents indicated that the important component of conducting research was a contribution to the new knowledge (45.5%) and to the scientific community (42.9%). More than half of respondents mentioned a professor or a peer as the initial motivation to become involved in research. Lack of time was the main limitation (59.7%) to research involvement. Perceived benefits were knowledge and team work skills. Of those involved, most (85.7%) wished to continue participating in research as a complement to their clinical work. Professors and student colleagues were found to play an important motivational and recruitment role for medical research. These efforts in turn have developed into long-lasting mentor-mentee relationships. Students also anticipated that early involvement in research will positively influence the likelihood of future physicians' contribution and collaboration in research. 相似文献
