Physical activity attenuates the symptoms of fibromyalgia, and its level is oftentimes associated with the perceived environment of fibromyalgia patients. Within this context, we aimed to study the reliability of the Spanish version of the Assessing Levels of Physical Activity (ALPHA) environmental questionnaire and the mode of commuting questionnaire. We also studied the association between the perceived environment and mode of commuting with physical activity levels among female fibromyalgia patients in Spain. Test–retest reliability was judged by the intra-class correlation coefficient (ICC), weighted kappa statistic, Spearman correlations and the proportion of agreement. We calculated bivariate Pearson’s correlations between environmental sum scores and physical activity measured by both International Physical Activity Questionnaire (IPAQ) and accelerometry. More than 70% of the scales and items showed a good reliability regarding the ICC, the weighted kappa, the Spearman correlation and the percentage of inter-agreement (higher than 50%). The perceived environment assessed with the ALPHA showed a low correlation with both IPAQ and accelerometry. The Spanish version of the ALPHA environmental questionnaire proved to be reliable and showed a weak degree of association with physical activity in female fibromyalgia patients.  相似文献

In the education world, it is widely accepted that language learning is one of the pioneering disciplines in the application and use of the information and communication technologies, initially preceded by the widespread use of audiovisual resources which, finally integrated in the digital space, bring about the use of multimedia. Additionally, language learning has greatly contributed to standardizing lesson plans. They set the basis for learning design, one of the last advances in the pedagogical organization of education through the use of computers in learning managing systems. Most recently, language learning has also played an innovative role in the implementation of portfolios to education. These three perspectives address different issues for e-learning: the access to content through technology; the design of the learning initially with the help of tutors and then applying institutional frameworks for their own personal learning processes; and the edition of the resulting e-learning experience as evidence with the e-dossier, a part of the e-portfolio. Currently, the web is evolving towards its original function as the read/write web where the user, apart from accessing information, can create their own information and communicate more interactively, using technology-enhanced learning environments to integrate text and multimedia for real audiences both in the classroom and outside. Thus, taking language learning guided by the Common European Framework of Reference for Languages, the authors present here a complete e-learning system which integrates textual as well as multimedia facilities to acquire learning content, edit learning design and report learning experiences.  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

There is interest in the accuracy and inter-unit reliability of position-tracking systems to monitor players. Research into this technology, although relatively recent, has grown exponentially in the last years, and it is difficult to find professional team sport that does not use Global Positioning System (GPS) technology at least. The aim of this study is to know the accuracy of both GPS-based and Ultra Wide Band (UWB)-based systems on a soccer field and their inter- and intra-unit reliability. A secondary aim is to compare them for practical applications in sport science. Following institutional ethical approval and familiarization, 10 healthy and well-trained former soccer players (20?±?1.6 years, 1.76?±?0.08?cm, and 69.5?±?9.8?kg) performed three course tests: (i) linear course, (ii) circular course, and (iii) a zig–zag course, all using UWB and GPS technologies. The average speed and distance covered were compared with timing gates and the real distance as references. The UWB technology showed better accuracy (bias: 0.57–5.85%), test–retest reliability (%TEM: 1.19), and inter-unit reliability (bias: 0.18) in determining distance covered than the GPS technology (bias: 0.69–6.05%; %TEM: 1.47; bias: 0.25) overall. Also, UWB showed better results (bias: 0.09; ICC: 0.979; bias: 0.01) for mean velocity measurement than GPS (bias: 0.18; ICC: 0.951; bias: 0.03).  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
