In order to adapt current subjects to the ECTS credits system, it is necessary to estimate how much time a student has to invest in learning a subject. The Polytechnic Engineering School of the University of the Basque Country has made an initial study to investigate this matter in several subjects. A weekly questionnaire design was used for all the students in the class, supplemented, when necessary, by an individual interview, with student collaboration. The results indicate that the study rhythm and the number of hours are strongly conditioned by the evaluation system. 相似文献

Sexual abuse in a national survey of adult men and women: prevalence, characteristics, and risk factors 总被引:40,自引:2,他引:40
This paper reports on the first national survey of adults concerning a history of childhood sexual abuse. Victimization was reported by 27% of the women and 16% of the men. Higher rates of abuse were found among men who grew up in unhappy families, lived for some period with only their mothers, who were currently residing in the West and who came from English or Scandinavian heritage. Higher rates of abuse were found among women who grew up in unhappy families, lived for some period without one of their natural parents, received inadequate sex education, were currently residing in the West or who were born after 1925. 相似文献

AbstractThis study investigated whether presenting a picture before reading can encourage situation-model construction. We compared two conditions (n?= 30) which differed in whether a picture of the initial situation described in a narrative text was presented before reading (i.e. pictorial-support condition) or not (i.e. no-picture condition). Situation-model construction was measured using both process- and product-oriented measures. Eye-tracking data indicated online resource allocation to the different levels of text representation: surface, textbase, and situation model. Literal text questions and inference questions were used as an offline indication of textbase and situation-model processing, respectively. The results showed that a picture presented before reading led to a redistribution of processing resources during reading, evidenced by a shift from textbase to situation-model processing. This attentional shift did not translate into higher comprehension scores. The results were interpreted in line with multimedia learning theories suggesting pictures can serve as a mental scaffold for situation-model construction. 相似文献

The seamless integration of reagents into microfluidic devices can serve to significantly reduce assay complexity and cost for disposable diagnostics. In this work, the integration of multiplexed reagents into thermoplastic 2D microwell arrays is demonstrated using a scalable pin spotting technique. Using a simple and low-cost narrow-bore capillary spotting pin, high resolution deposition of concentrated reagents within the arrays of enclosed nanoliter-scale wells is achieved. The pin spotting method is further employed to encapsulate the deposited reagents with a chemically modified wax layer that serves to prevent disruption of the dried assay components during sample introduction through a shared microchannel, while also enabling temperature-controlled release after sample filling is complete. This approach supports the arbitrary patterning and release of different reagents within individual wells without crosstalk for multiplexed analyses. The performance of the in-well spotting technique is characterized using on-chip rolling circle amplification to evaluate its potential for nucleic acid-based diagnostics. 相似文献

We carried out an empirical study of aggression in relation to different personal traits. In this article we present results obtained for different forms of aggression, including results of machine-learning experiments with the AQJSM method. The method distinguishes several classes with different levels of aggression defined with a special form, as well as making causal inferences with AQ preprocessing and the first stage of JSM method of extraction of cause and effect relationships. The proposed method produces acceptable results for both small datasets and big data with incomplete information. 相似文献

The results from analyzing the scientific output of scientists from the Novosibirsk oblast’ are given based on works published
in 2005–2009. The analysis was carried out using the data and potential of the Web of Science (WoS) and, in particular, information
about domestic and foreign science foundations that supported particular studies, Journal Citation Reports, HistCite software,
and certain additional data that included official statistics from Rosstat and involved indicators derived from the journal impact factor and the aggregate impact factor of the WoS knowledge category. The publications by the scientists from the oblast’ were distributed according to 133 WoS knowledge categories. Research
in certain trends in 48 WoS knowledge categories carried out in the oblast’ is in no way inferior to and very often is even
better than the global science standards. More than 50% of the publications were sponsored by domestic and foreign science
foundations: the scientific quality of these works was considerably higher than that of the unsponsored studies. The coauthors
of the articles published by scientists of the oblast’ in the period were their colleagues from 83 countries. R & D costs
in the Novosibirsk oblast’ are used quite efficiently: in 2009 the publications by the scientists of the oblast’ accounted
for more than 9% of the entire amount of works published all over Russia, while internal research and development expenses
were only 2.5% of such expenses nationwide. 相似文献
