Despite the growing body of research on work engagement, little is known about what drives work engagement among different age cohorts. This study aims to investigate whether engagement varies across age cohorts and examine the job resources that foster teacher engagement. A questionnaire was distributed to 537 teachers who were employed in elementary, lower and upper secondary school. Findings show that work engagement did indeed vary across the diverse age group and is influenced by different resources. In line with previous studies, data revealed that the engagement of younger teachers is driven by the opportunity for development and interaction with colleagues, while older employees appreciate the opportunity to see their competencies acknowledged. What is most noteworthy is the opportunity to design practices and to provide every age group with the appropriate set of motivators. 相似文献

Recent research findings suggest that students who have difficulty learning a second language have weaknesses in oral and
written native-language skills which affect their performance in the foreign-language classroom. These weaknesses involve
understanding the phonological, syntactic, and semantic codes of language. Evidence suggests that dyslexic/learning-disabled
and other “at risk” students who struggle in the second language classroom exhibit particular difficulty with the phonological
and syntactic codes of the language. The Orton-Gillingham method, a multisensory, structured language approach which adheres
to the direct and explicit teaching of phonology, is presented as an alternative to the “natural” communication approaches
recently developed by foreign-language educators to teach a second language. A method for adapting this approach for teaching
Spanish is described. 相似文献

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

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

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

IntroductionSeveral laboratory tests are characteristically altered in Coronavirus Disease 2019 (COVID-19), but are not totally accurate in predicting the disease outcome. The long pentraxin 3 (PTX3) is quickly released directly at inflammation sites by many immune cell types. Previous studies have shown that PTX3 correlated with disease severity in various inflammatory conditions. Our study investigated the use of PTX3 as a potential marker of COVID-19 severity and compared its performance in detecting a more severe form of the disease with that of routine laboratory parameters.Materials and methodsStored serum samples of RT-PCR confirmed COVID-19 cases that had been obtained at hospital admission were retrospectively analysed. Intensive care unit (ICU) stay was considered a surrogate endpoint of severe COVID-19. Pentraxin 3 was measured by a commercial enzyme-linked immunosorbent assay.ResultsA total of 96 patients were recruited from May 1st, 2020 to June 30th, 2020; 75/96 were transferred to ICU. Pentraxin 3 was higher in ICU vs non-ICU patients (35.86 vs 10.61 ng/mL, P < 0.001). Univariate and multivariate logistic regression models demonstrated that the only significant laboratory predictor of ICU stay was PTX3 (OR: 1.68 (1.19-2.29), P = 0.003), after controlling for comorbidities. The Receiver Operator Characteristic curve analysis showed that PTX3 had a higher accuracy compared to C-reactive protein (CRP), lactate dehydrogenase (LD), ferritin in identifying ICU patients (AUC of PTX3 = 0.98; CRP = 0.66; LD = 0.70; ferritin = 0.67, P < 0.001). A cut-off of PTX3 > 18 ng/mL yielded a sensitivity of 96% and a specificity of 100% in identifying patients requiring ICU.ConclusionHigh values of PTX3 predict a more severe COVID-19. 相似文献

Reading minds: the relation between children's mental state knowledge and their metaknowledge about reading 总被引:1,自引:0,他引:1
The relation between children's mental state knowledge and metaknowledge about reading was examined in 2 studies. In Study 1, 196 children (mean age = 9 years) were tested for verbal ability (VA), metaknowledge about reading, and mental state words in a story task. In Study 2, the results of Study 1 were extended by using a cross-lagged design and by investigating older children (N = 71, mean ages = 10 years at Time 1 and 11 years at Time 2) for mental state knowledge, metaknowledge about reading, and VA. Results showed a significant relation between early cognitive (but not emotion) mental state knowledge and later metaknowledge about reading, controlling for VA. Results suggest close links between different aspects of children's knowledge about the mind. 相似文献

Using data from a post-test only experiment with random assignment, this article examines whether differing music genres influence socially relevant decisions made by listeners. A sample of White college students was exposed to1 of 3 music genres during an ostensible waiting period, and was then asked to allocate funding to projects for different ethnic groups. Three music conditions—radical White power rock, mainstream rock, and Top 40 pop music—were examined to determine whether differential allocations to ethnic groups would emerge following music exposure. As expected, Top 40 pop music exposure led to equal allocations to the various ethnic groups. After listening to mainstream rock, participants allocated significantly higher budgets to White Americans compared to all other race groups. After listening to radical White power rock music, participants also allocated significantly higher budgets to White Americans, but changes in allocations to ethnic minority groups also emerged. Namely, African Americans and Arab Americans received particularly low funding from participants exposed to radical White power rock music. 相似文献
