AbstractThe objective of this study was to obtain evidence about the cross-cultural validity of the ‘Subjective Resilience Questionnaire’ (SRQ), comparing French and Spanish Secondary and High School students’ results. A total of 750 French students formed the sample. To validate the SRQ, confirmatory factor analyses, reliability and correlation and regression analyses were made. The validation process included the analysis of the generalizability of factor structure, and of relationships of resilience scores with different kinds of protective and vulnerability factors — success expectancies and learning-oriented classroom motivational climate (CMC). French results were similar to Spanish results, underlying the importance of considering variations in resilience as a function of the kinds of adversity experienced. Nevertheless, some differences between French and Spanish students were found in the degree they recognize to act in a resilient way in some of the situations covered by SRQ, differences whose theoretical and practical implications for education are discussed. 相似文献

In Java, System.out.printf and String.format consume a specialised kind of string commonly known as a format string. In our study of first-year students at the Ateneo de Manila University, we discovered that format strings present a substantial challenge for novice programmers. Focusing on their first laboratory we found that 8% of all the compilation errors and 100% of the exceptional, run-time behaviour they encountered were due to the improper construction of format strings. Format strings are a language unto themselves embedded within Java, and they are difficult for novice programmers to master when learning to program. In this article, we present exemplars of students' problematic interactions with the Java compiler and run-time environment when dealing with format strings, discuss these interactions, and recommend possible instructional interventions based on our observations. 相似文献

Previous studies have indicated that A‐level students in the UK and Singapore have difficulty learning the topic of ionisation energy. A two‐tier multiple‐choice instrument developed in Singapore in an earlier study, the Ionisation Energy Diagnostic Instrument, was administered to A‐level students in the UK, advanced placement high school students in the USA, and first‐year university students in China, New Zealand, and Spain to determine whether the students from different countries and educational systems had similar conceptions and difficulties as the students in Singapore with the concepts assessed in the instrument. The results showed that, in general, the students in all six samples had similar alternative conceptions, which were grouped under the categories of octet rule framework, stable fully‐filled and half‐filled subshell conceptions, and conservation of force thinking. The students also resorted to relation‐based thinking when answering items involving the trend of ionisation energies across Period 3. Implications for teaching and further research are discussed. 相似文献

ABSTRACT— The aim of the current study was to examine the role of individual differences in neurocognitive and temperamental systems of self‐regulation in early adolescents’ social and academic competence. Measures used in the study included the Attention Network Test, the Early Adolescence Temperament Questionnaire, a peer‐reported Social Status Questionnaire, a self‐reported measure of Schooling Skills, and information on grades obtained by the students in a variety of school subjects (n= 69 12‐year olds). Results showed that efficiency of the neurocognitive network of executive attention is related to academic outcomes, particularly in mathematics, as well as to aspects of social adjustment. Temperamental effortful control appears to be a significant predictor of all dimensions of school competence assessed in this study and mediates the relationship between social adjustment and poor schooling outcomes. These data suggest that individual differences in systems of self‐regulation are central to understanding processes of learning and social adjustment in the school. 相似文献

Some cognitive dimensions are internationally considered by psychologists to describe and to assess creativity. For example, (Guilford, P. (1976). Creatividad y Educación. Buenos Aires. Ed. Paidos) and (Torrance, E. P. (1977). Discovery and nurturance of giftedness in the culturally different. Reston, VA: Council on Exceptional Children) suggested fluency, flexibility, originality and elaboration are the main cognitive processes used to define and assess creativity. However, data from several empirical studies did not confirm a factor structure in accordance with such cognitive functions, despite of the wide use of TTCT (Torrance Tests of Creative Thinking) in different countries. In this paper, we present new data collected in Spain and Portugal with TTCT. According to our data, those cognitive functions supposedly present on a subject's performance are not so strong as to explain the variance in scores. Elaboration factors assume some variance explanation, but the main factors are identified with the products in each subtest, suggesting the importance of format, content and demand on TTCT specific tasks. Consequently, we suggest some reflections to amplify the debate concerning the definition of creativity and its evaluation in psychology. 相似文献

References to parts of structured documents use their structure to locate the piece of document which is the reference target. On the other hand, XML has become an increasingly important language for structured documents. One of its most important related languages is XPath, the language that permits fragments of XML documents to be selected. In this article we present a methodology, and an application case, to automatically extract and solve references to fragments of structured documents. This approach combines structure manipulation and information extraction, to enhance reference extraction tools by improving the precision of the references extracted. We take advantage of XML markup to locate the position within the structure in which the references are found. The use of XPath, one of the most important XML related languages, for reference resolution is original: the resolution tool automatically builds XPath expressions. This proposal is inspired (and implemented) from our work with legislative documents. 相似文献

Clusters,convergence, and economic performance 总被引：1，自引：0，他引：1
This paper evaluates the role of regional cluster composition in regional industry performance. On the one hand, diminishing returns to specialization in a location can result in a convergence effect: the growth rate of an industry within a region may be declining in the level of economic activity of that industry. At the same time, positive spillovers across complementary economic activities can provide an impetus for agglomeration: the growth rate of an industry within a region may be increasing in the “strength” (i.e., relative presence) of related industries. Building on Porter (1998, 2003), we develop a systematic empirical framework to analyze the role of regional clusters – groups of closely related industries operating within a particular region – in the growth of regional industries. We exploit data from the US Cluster Mapping Project to examine the effects of agglomeration within regional clusters after controlling for convergence at the region-industry level. Our findings suggest that industries located in a strong cluster register higher employment and patenting growth. Regional industry growth also increases with the strength of related clusters in the region and with the strength of similar clusters in adjacent regions. We also find evidence of the complementarity between employment and innovation performance in regional clusters: both the initial employment and patenting strength of a cluster have a separate positive effect on the employment and patenting growth of the constituent industries. Finally, we find that new regional industries emerge where there is a strong cluster. These findings are consistent with multiple types of externalities arising in clusters, including knowledge, skills, and input–output linkages. 相似文献

Students of color are overrepresented in school disciplinary records nationally, but little is known about how disciplinary disproportionality varies among groups. Classroom observations in 1 elementary school suggested that when Latino students misbehaved, teachers were less inclined to interpret their behavior as problematic and less inclined to discipline them than their African American peers. Interpretations of behavior developed relationally, as teachers assessed behavior and compared it to that of students whom they considered problematic. Compared to students with “impulse control problems,” Latino students developed a positive reputation and avoided the cycle of disciplinary processes in which their peers found themselves. 相似文献

Introduction
Preanalytical control and monitoring continue to be an important issue for clinical laboratory professionals. The aim of the study was to evaluate a monitoring system of preanalytical errors regarding not suitable samples for analysis, based on different indicators; to compare such indicators in different phlebotomy centres; and finally to evaluate a single synthetic preanalytical indicator that may be included in the balanced scorecard management system (BSC).Materials and methods
We collected individual and global preanalytical errors in haematology, coagulation, chemistry, and urine samples analysis. We also analyzed a synthetic indicator that represents the sum of all types of preanalytical errors, expressed in a sigma level. We studied the evolution of those indicators over time and compared indicator results by way of the comparison of proportions and Chi-square.Results
There was a decrease in the number of errors along the years (P < 0.001). This pattern was confirmed in primary care patients, inpatients and outpatients. In blood samples, fewer errors occurred in outpatients, followed by inpatients.Conclusion
We present a practical and effective methodology to monitor unsuitable sample preanalytical errors. The synthetic indicator results summarize overall preanalytical sample errors, and can be used as part of BSC management system.Key words: Preanalytical phase, errors in laboratory medicine, balanced scorecard, patient safety 相似文献70.

This article is focused on the analysis of the narratives produced by a group of teachers, experts in coeducation, while they were discussing their everyday activities. They are responsible for the implementation of a Plan for Gender Equality in public secondary schools in Andalusia (Spain). This study is based on contributions about doing gender view, according to which gender is not an attribute of individuals, but a way of making sense of interactions and practising a complex system as functioning on three levels: sociocultural, interactional, and individual. We use these levels to understand gender culture in schools through teachers’ discourse. Our interest lies particularly in the meanings, contradictions, difficulties, and conflicts experienced by expert teachers in co-education. Our study was based on group discussions with teachers in charge of the plan for equal opportunities between women and men in school settings. Results show teachers’ conflicts about meanings and how they are supposed to apply the Equality Plan. We observed interactional levels during these conflicts and analysed how teachers construct and validate their discourse. 相似文献
