The learning analytics (LA) field seeks to analyze data about students’ interactions, and it has been applied in the development of tools for supporting both learning and teaching processes. Recent research has paid attention on how LA may benefit teachers in the creation of educational resources. However, most of the research on LA solutions is carried out to support teachers in analyzing students’ behavior data collected as they interact with virtual learning environments. While solutions to support teachers in different virtual learning and teaching contexts have become important, to date little research has been done on how LA solutions can help teachers to create and evaluate Open Educational Resources (OERs). This study aims at presenting the evaluation of a LA tool for supporting teachers in the creation and evaluation of accessible and quality OERs considering that both processes fall within the competences that teachers can acquire and strengthen by participating as authors (creation) and evaluators (evaluation) of OERs. The study was conducted with Colombian teachers and the results obtained highlight the positive effect the tool had on the teachers’ acquisition of the competences and the positive attitude they had toward using the tool.  相似文献   

Project Management Techniques at the Complutense University: Academic Librarians' Perceptions     

Silvia Cobo Serrano  Rosario Arquero Avilés 《New Review of Academic Librarianship》2018,24(2):124-135

This study examines how academic librarians at the Complutense University (Spain) perceive project management techniques that are becoming increasingly popular in library and information centers due to the need to comply with their strategic planning and services. To reach this goal, a quantitative and qualitative methodology was applied and a survey, in the form of a questionnaire, was used as a data gathering tool. The response rate was 31.2%. The key findings are based on respondents' education regarding project management skills and their expertise managing projects, as well as the presence of project management courses in the Library and Information Science Spanish curriculum. This study revealed that over one third of the academic staff completed their project management training by self-directed learning. Additionally, over half of them stated that they had not participated in any library project in the last five years, and almost half of the library staff concluded that project management techniques are quite important as formal courses in the Library and Information Science university programs. The study is interesting and revealing for those library and information services professionals who are facing day-to-day to users' demands and Library and Information Science challenges.  相似文献   

Ethanol as an antifungal treatment for paper: short-term and long-term effects     

Silvia O. Sequeira  Alan J. L. Phillips  Eurico J. Cabrita  Maria F. Macedo 《文物保护研究》2017,62(1):33-42

In paper conservation ethanol is used as an antifungal agent. However, information on the antifungal efficacy of this alcohol is scarce and often inconsistent. In this study, we clarify if ethanol is effective and safe to use in paper conservation in the short as well as in the long term. None of the tested ethanol concentrations (5–100%) promoted conidia germination, but rather delayed or entirely inhibited it, depending on alcohol concentration and contact time. In a simulation of an interventive treatment of samples colonized by fungi, all the tested ethanolic solutions (30, 70, and 100%) revealed antifungal activity. The best results were obtained with 70% ethanol, showing fungicidal properties on four of the five-tested fungal species (Aspergillus niger, Cladosporium cladosporioides, Penicillium chrysogenum, and Penicillium corylophilum). No deleterious effects of 70% ethanol on the tested paper were observed either in the short or in the long term.  相似文献   

Twitter and Television in a Hybrid Media System     

Rita Marchetti 《Journalism Practice》2016,10(5):626-644

By analyzing all of the keywords and hashtags that became Trending Topics (TTs) in the Italian Twittersphere during both an electoral period and a non-electoral period, we evaluated what Italian Twitter users discussed. We found that topics about actors and issues in the entertainment field (e.g., singers, Hollywood stars and television stars) drive Italian discussions and that the political sphere is a secondary topic that elicits minor arguments within users’ conversations. However, we believe that even this low level of discussion about politics was able to influence the public agenda, thanks to the advent of a hybrid media system in Italy. In fact, Italian print media and television constantly covered the individual tweets or hashtags of a niche of citizens who were discussing politics on Twitter. Television, a part of the Italian media system that is highly consumed by the public, is also a primary factor in determining the appearance of a specific actor or issue on the TT list. Furthermore, we empirically confirmed the logic of breaking news events on Twitter, a microblogging site that primarily focuses on exceptional occurrences.  相似文献

Inflectional morphology and dyslexia: Italian children’s performance in a nonword pluralization task     

Maria Vender  Federica Mantione  Silvia Savazzi  Denis Delfitto  Chiara Melloni 《Annals of dyslexia》2017,67(3):401-426

In this study, we present the results of an original experimental protocol designed to assess the performance in a pluralization task of 52 Italian children divided into two groups: 24 children with developmental dyslexia (mean age 10.0 years old) and 28 typically developing children (mean age 9.11 years old). Our task, inspired by Berko’s Wug Test, had the aim of testing the subjects’ ability to apply pluralization rules to nonwords in the morphologically complex context of Italian nominal inflection. Results demonstrate that dyslexics display poorer morphological skills in comparison to controls, showing lower accuracy in the task. Furthermore, the dissimilar performances reported by the subjects in the different conditions indicate that the ability to inflect nonwords depends on factors such as the rule’s productivity, frequency, and opacity with respect to gender. Finally, the children’s performance in this task was significantly related to their reading proficiency, and it could predict accuracy in word reading independently of phonological awareness and working memory.  相似文献   

Child and partner abuse: self-reported prevalence and attitudes in the north of Portugal     

Machado C  Gonçalves M  Matos M  Dias AR 《Child abuse & neglect》2007,31(6):657-670

OBJECTIVES: To determine the self-reported prevalence of child and partner physical and emotional abuse in the north of Portugal and to investigate attitudes about these forms of family violence. METHODS: Data were collected by questionnaire from a representative sample of parents in two-parent families with children under the age of 18 years. A total of 2,391 parents participated (1,057 males), aged 20-67 years. Four questionnaires were used, one behavioral and one attitudinal, for each of the forms of abuse: child and partner. RESULTS: At least one act of emotional or physical abuse towards a child during the previous year was reported by 25.9% of participants (12.3% reported physically abusive and 22.4% emotionally abusive acts). Abuse of a partner was reported by 26.2% of participants; at least one act of physical abuse during the previous year was reported by 12% and of emotional abuse by 23.7%. The attitudinal data, however, showed general disapproval of the use of violence, both for disciplining children and within marital relationships. The degree of self-reported support for physical punishment was higher in participants who reported using abusive behavior. Females more commonly reported acts of child abuse, and males reported acts of partner abuse. Both forms of self-reported abuse showed an association with low educational and socio-economic status. CONCLUSIONS: This is the first study in Portugal to analyze family violence through self-report using a representative sample. The findings indicate that child and partner abuse constitute a significant problem in the region of northern Portugal. The discrepancy between the self-reported behavioral and attitudinal data may reflect conflicts in Portuguese society, which is undergoing substantial cultural changes.  相似文献
