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   

Serial position effects in social transmission of food preference     

Juárez-Maldonado CE  Ortega-Saavedra G  Huichan-Olivares F  Gómez-Romero J  Cruz-Morales SE  Arriaga-Ramírez JC 《Learning & behavior》2006,34(4):374-378

The serial position effect in Long-Evans rats was evaluated in two experiments. In Experiment 1, the effect in a group for which an interstimulus interval (ISI) was introduced between items in a list of demonstrators was compared with that in a group without an ISI. With an ISI, a recency effect was produced. In Experiment 2, a serial position effect group was compared with four groups in which either the distinctiveness or the context of the middle item was changed, relative to the items on either side of it. A von Restorff effect was produced when a rat from a different strain was used as a demonstrator in Position 2. The results for Experiment 1 are discussed in relation to interstimulus effects in monkeys and those for Experiment 2 with respect to changes in the physical properties of middle items.  相似文献

Postural control quantification in minimally and moderately impaired persons with multiple sclerosis: The reliability of a posturographic test and its relationships with functional ability

BackgroundPostural control has been associated with the functional impairment in persons with multiple sclerosis (pwMS). However, there is a need for reliable methods to assess postural control in early stages of the disease, when subtle changes can be difficult to detect. The aims of this study were to assess the absolute and relative reliability of a standing and a sitting posturographic protocol in minimally (Expanded Disability Status Scale ≤ 2) and moderately (2.5 ≤ Expanded Disability Status Scale ≤ 4) impaired pwMS, and to analyze relationships among postural control and functional mobility and gait performance.MethodsTo assess postural control in an upright stance, 14 minimally and 16 moderately impaired pwMS performed six 70 s trials in tandem stance, 3 with their weaker leg behind (TS_WL) and 3 with their stronger leg behind (TS_SL). Additionally, participants completed five 70 s trials using an unstable sitting protocol (US) to assess trunk stability. The mean radial errors of TS_WL, TS_SL, and US trials were calculated as postural control indexes. Furthermore, participants performed the Timed Up and Go test (TUG) and the Timed 25-foot Walk test (T25FW) to measure their functional mobility and gait speed, respectively. Reliability was evaluated using the intraclass correlation coefficient (ICC_3,1) and the standard error of measurement (SEM). Analyses of variances were carried out to assess between-group differences. Hedges’ g index (d_g) was used to estimate the effect size of differences. Pearson correlation analyses (r) were performed to examine the relationships among the postural control and the functional tests.ResultsPosturographic tests showed a high reliability in both minimally (0.87 ≤ ICC ≤ 0.92; 9.32% ≤ SEM ≤ 11.76%) and moderately (0.80 ≤ ICC ≤ 0.92; 10.33% ≤ SEM ≤ 15.33%) impaired pwMS. Similarly, T25FW and TUG displayed a high consistency in minimally (0.89 ≤ ICC ≤ 0.94; 3.43% ≤ SEM ≤ 5.17%) and moderately (0.85 ≤ ICC ≤ 0.93; 5.57% ≤ SEM ≤ 6.56%) impaired individuals. Minimally impaired pwMS showed a better performance on the TUG, T25FW, and TS_WL than moderately impaired individuals (p < 0.05; d_g ≥ 0.8). The TS_WL, TS_SL, and US variables correlated with TUG scores (0.419 ≤ r ≤ 0.604; p < 0.05), but TS_WL also correlated with T25FW scores (r = 0.53; p < 0.01). Furthermore, US scores correlated with both tandem stance parameters (TS_WL: r = 0.54, p < 0.01; TS_SL: r = 0.43, p < 0.05).ConclusionTandem and sitting posturographic tests provide reliable measures of postural control in pwMS, even in individuals with a homogeneous disease profile. Gait speed, functional mobility, and weaker leg status seem decisive in assessing the degree of physical activity limitation in pwMS. Finally, although trunk stability does not seem to be so affected by the course of the disease, it remains relevant for postural control and functional capacity.  相似文献   

Learning,unlearning and internationalisation: Evidence from the pre-export phase     

José C. Casillas  Francisco J. Acedo  José L. Barbero 《International Journal of Information Management》2010

The internationalisation process has been described as a process of learning under which a business increases its commitment abroad as the company acquires knowledge on new markets and on the nature of the process itself. The present work proposes a model that relates the possession of a base of knowledge originated in supra-organisational, organisational and individual sources, as the actively new decision of seeking knowledge related to the start of the exporting activity. Integrating the literature on the pre-export behaviour of the business and the theory of organisational learning, we propose that such relationship is influenced by two dimensions: the export intention and the context of unlearning. The sample included 103 SMEs in the pre-exporting phase. Results support the conception of the process of internationalisation as a process of learning under which a prior base of knowledge is combined with periods of unlearning and a search for new knowledge.  相似文献   

University Efficiency: Complementariness versus Trade‐off between Teaching,Research and Administrative Activities     

Ricardo Sellers‐Rubio  Francisco J. Mas‐Ruiz  Ana B. Casado‐Díaz 《Higher Education Quarterly》2010,64(4):373-391

University managers should be aware of the importance that efficiency has for their own universities, orientating their actions towards research and teaching excellence. This study estimates teaching and research efficiency of the different departments of a university and tests the complementariness versus trade‐off between them. The results obtained show high levels of efficiency for the departments analysed, which is important for budget allocation, as one of the main challenges faced by a university is the allocation of budgets to different departments. The results also support the trade‐off between teaching efficiency and research activity, the complementariness between teaching efficiency and research efficiency, between research efficiency and time deducted from teaching, as well as the complementariness between research efficiency and administration activity.  相似文献
