This work describes the genesis, articulation and consolidation from 2007 of a social network of b-learning (blended learning) in the UA (University of Alicante) (Spain), with the institutional backing of the Office of the Vice President for Education Technology and Innovation, and the momentum and advice of professor Angel Fidalgo (UNESCO (United Nations Educational, Scientific and Cultural Organization) chair for University of Management and Policy). The social network currently has more than 25 teachers, working on different work linkages with the university, implementing or intending to apply the teaching methodologyb-learning during the course 2007-2008 in a variety of courses and degrees. To do so, several resource centers (blogs, wikis, Wimba Create (before CourseGenie), etc.), and digital platforms (Virtual Campus of the UA, Moodle, etc.) are used. 相似文献

Between General Franco's agony (October/November 1975) and the constitution's approval (December 1978), European media reported intensively about the democratisation process in Spain. The present paper deals with its examination through the Radio della Svizzera di lingua italiana broadcasts. As the only Swiss Italian-speaking broadcaster, it tried to provide in-depth information and opinion on a country whose solid ties with Switzerland were based on economy, migration and tourism. The study of this non-commercial radio allows us to determine the way the democratisation was approached and portrayed for a Swiss audience and offers a genuine case for transnational historical research. 相似文献

This article exposes the ancient Nepohualtzitzin as an important contemporary mathematical tool. The design and development of Nepohualtzitzin Ethnomathematics Clubs (NECs) in predominantly Latina/o and low-income schools is also presented. NECs provide informal learning opportunities to develop and strengthen cultural connections to and abilities in mathematics for bicultural-bilingual learners, their parents, and teacher candidates. The formation of NECs is made possible through transnational alliances developed over time between the University of Texas at San Antonio, Secretaría de Educación Pública de México (Ministry of Public Education of Mexico), Coahuiltecan Indian Nation, Aztlán Associates, Danza Azteca Xinachtli, and Tzicatl—Community Development Corporation. 相似文献

This study aimed to analyse the association of different components of physical fitness, body composition, cardiometabolic markers and the Mediterranean diet with bone mineral density (BMD) in perimenopausal women, and to test which of these components are independently associated with BMD. The sample comprised 197 perimenopausal women (52.6 ± 4.5 years). Physical fitness was assessed with the “Senior Fitness Test” battery and the handgrip strength and Bruce tests. Fat and lean mass and BMD were measured using dual-energy X-ray absorptiometry. We analysed the markers of metabolic syndrome, C-reactive protein, and components of the Mediterranean diet. Handgrip muscle strength (β = 0.212, P = 0.005), body weight (β = 0.244, P = 0.001), BMI (β = 0.180, P = 0.011) and lean mass (β = 0.379, P < 0.001) were positively associated with BMD. No associations were observed between cardiometabolic markers or the Mediterranean diet with BMD (all P > 0.05). When all relevant indicators of BMD were simultaneously considered, lean mass was the only 1 showing an independent association with BMD (β = 0.392, P < 0.001), explaining 14% of the BMD variability. In conclusion, muscle strength might be a marker of BMD in perimenopausal women. However, lean mass was the only factor independently associated with BMD. Future research to determine whether increasing lean mass through specific exercise-based interventions contributes to increasing BMD is warranted. 相似文献

IntroductionThe Fourth Universal Definition of Myocardial Infarction Global Taskforce recommends the use of high sensitive troponin (hs-Tn) assays in the diagnosis of acute myocardial infarction. We evaluated the analytical performance of the Atellica IM High-sensitivity Troponin I Assay (hs-TnI) (Siemens Healthcare Diagnostics Inc., Tarrytown, USA) and compared its performance to other hs-TnI assays (Siemens Advia Centaur, Dimension Vista, Dimension EXL, and Abbott Architect (Wiesbaden, Germany)) at one or more sites across Europe.Materials and methodsPrecision, detection limit, linearity, method comparison, and interference studies were performed according to Clinical and Laboratory Standards Institute protocols. Values in 40 healthy individuals were compared to the manufacturer’s cut-offs. Sample turnaround time (TAT) was examined.ResultsImprecision repeatability CVs were 1.1–4.7% and within-lab imprecision were 1.8–7.6% (10.0–25,000 ng/L). The limit of blank (LoB), detection (LoD), and quantitation (LoQ) aligned with the manufacturer’s values of 0.5 ng/L, 1.6 ng/L, and 2.5 ng/L, respectively. Passing-Bablok regression demonstrated good correlations between Atellica IM analyser with other systems; some minor deviations were observed. All results in healthy volunteers fell below the 99th percentile URL, and greater than 50% of each sex demonstrated values above the LoD. No interference was observed for biotin (≤ 1500 µg/L), but a slight bias at 5.0 g/L haemoglobin and 50 ng/L Tn was observed. TAT from was fast (mean time = 10.9 minutes) and reproducible (6%CV).ConclusionsReal-world analytical and TAT performance of the hs-TnI assay on the Atellica IM analyser make this assay fit for routine use in clinical laboratories. 相似文献

Prior research studies associated the employment of part-time faculty with student degree and/or certificate completion (Benjamin, 2002; Ehrenberg & Zhang, 2005; Jacoby, 2006; Leslie & Gappa, 2002; Umbach, 2008; Umbach & Wawrzynski, 2005). To date, institutional-level data have been utilized to investigate whether such employment adversely associated with student degree and/or certificate completion in two-year community colleges. Little research, however, has been conducted to study such association utilizing both student and institutional-level data (e.g., Eagan & Jaeger, 2009; Jacoby, 2006). In this study, we draw data from Integrated Postsecondary Education Data System (IPEDS) and The Beginning Postsecondary Students Longitudinal Study (BPS: 04/09), and employ a multilevel logistic regression model to investigate whether the proportion of part-time faculty is negatively associated with individual student’s likelihood of degree and/or certificate completion. Analytical results indicate the proportion of part-time faculty in community colleges is not negatively associated with student’s likelihood of degree and/ or certificate completion. 相似文献

In recent years, there have been increasing calls for an overall transformation of the nature of engineering Ph.D. programs and the way theses are assessed. There exists a need to understand the examination process to ensure the best quality outcome for candidates in engineering. The work we present in this paper uses data collected between 2003 and 2010 for a total of 1220 Australian Ph.D. theses by analysing examiner reports. Our analysis indicates that Ph.D. theses in engineering, N?=?106, differ considerably from those in other fields in areas such as gender of candidates and examiners and the examiners’ geographical location. We also found that assessment areas such as significance and contribution of the thesis, publications arising from the thesis, breadth, depth and recency of the literature review and communication and editorial correctness are areas in which the proportion of text of engineering examiners' comments differs significantly from other fields. 相似文献

This study, based on the theoretical model of Teacher Self-Efficacy proposed by Denham and Michael (1981), explored the effects
of prior training, previous teaching experience, and certain demographic variables on the teaching self-efficacy of graduate
teaching assistants. An adapted version of the Self-Efficacy Toward Teaching Inventory (Tollerud, 1990) was administered to
a sample of graduate teaching assistants. Graduate teaching assistants with prior training endorsed a significantly higher
level of self-efficacy than those with no training. Correlational analyses demonstrated significant positive relationships
between prior training and previous teaching experience with level of self-efficacy. Multiple regression analysis indicated
that previous teaching experience explained a significant amount of variance in self-efficacy. Results are discussed in light
of the current training and utilization of graduate teaching assistants, and suggestions for future research are offered.
