The purpose of this research was to build and test a conceptual model of the complex interrelationships between students' learning in science (learning approaches and self-regulation), their reading comprehension, question-asking in class and science achievement. These variables were measured by means of a test and a series of questionnaires administered to 604 ninth-grade students, and the data collected were analysed using a correlational, cross-sectional design. Results of a path analysis indicated that (a) students’ self-regulated and intentional knowledge-constructing activity (self-regulated strategy use, deep approach and knowledge-building) were what chiefly accounted for their question-asking in class; (b) question-asking (high and low levels) was related directly to reading comprehension and indirectly, through its contribution to the this, to academic achievement; (c) reading comprehension was directly and negatively associated with surface approach and indirectly and positively related to deep approach and knowledge-building; and (d) some of these variables, particularly reading comprehension, accounted for academic achievement in science. This model explained nearly 30% of the variance in academic achievement and provided a substantial and distinctive insight into the web of interrelationships among these variables. Implications for future research and science teaching and learning are discussed (e.g. the importance of supporting students' efforts to learn science in a meaningful, active and self-regulated way and of improving their reading comprehension).  相似文献

Making the development of technological innovations more efficient: An exploratory analysis in the biotechnology sector     

Fernando E. García-Muiña  Eva Pelechano-Barahona  José E. Navas-López 《The Journal of High Technology Management Research》2009,20(2):131-144

The current study analyzes the processes involved in obtaining technological innovations. Conclusive results are lacking in the literature, so this work defines and empirically tests a model of the relations between the firm's innovative capacity and the different ways of accumulating knowledge and the decision whether or not to codify it. Also, the model takes into account whether the innovations obtained are radical or incremental.The empirical study uses a sample of Spanish biotechnology firms, and the results show that accumulating knowledge using internal sources and not codifying it significantly improves the firm's capacity to develop radical innovations. The results also show that knowledge codification speeds up the development of incremental innovations. The relation between incremental innovations and the sources of knowledge is not so clear, although the results suggest the possible existence of a nonlinear relation between the two variables.  相似文献   

Defining the problem: key element for the success of knowledge management     

Mario?Barcelo-ValenzuelaEmail author  Gerardo?Sanchez-Schmitz  Alonso?Perez-Soltero  Fernando?Martín Rubio  José?Palma 《知识管理研究与实践》2008,6(4):322-333

The objective of this paper is to propose a methodology for applying knowledge management (KM), in which we first focus on explaining problematic areas of an organization by identifying the knowledge core process, before applying KM strategies to those processes. For the methodology, we lean on the larger context of systems thinking to help visualize the whole organization, and it is here that the key factors are identified and a set of strategic criteria is established. The most important criteria are then used to evaluate the associated processes and their respective tasks in order to establish the problematic areas or opportunities where KM initiatives can be applied. This strategy precludes tackling all the organization's problems and allows management to focus on only those processes that provide significant and manageable knowledge. Finally, this study explores and cautiously recommends an unexploited but valuable element to be taken into account when implementing KM initiatives.  相似文献   

Analysis of foot strike pattern,rearfoot dynamic and foot rotation over childhood. A cross-sectional study     

Pedro Ángel Latorre Román  Fernando Redondo Balboa  Juan Párraga Montilla  Víctor Manuel Soto Hermoso  Pedro José Consuegra González  Felipe García Pinillos 《Journal of sports sciences》2019,37(5):477-483

The purpose of this study was to determine the foot strike patterns (FSP), rearfoot position at initial contact (RPic, i.e., No INV/EVE) and foot rotation in children in relation to age. A total of 932 children aged 3 to 16 years participated in this study. A sagittal and frontal-plane video was recorded using a high-speed camcorder to analyse these variables. There is a significant increase (p < 0.001) of rearfoot strike patterns (RFS) prevalence in relation to age; e.g. preschool children (3–6 years old) displayed an RFS prevalence 46.65% and the adolescent population(15–16 years old) an RFS prevalence 92.20%. The total RFS prevalence in all samples was 69.25%. There was a significant reduction (p < 0.001) of prevalence of RPic in relation to age groups; preschool children displayed a prevalence of RPic 60.37% and the adolescent population 10%. There was a significant reduction (p < 0.001) of prevalence of no foot rotation in relation to age groups; preschool children displayed a prevalence of no foot rotation 48.95% and the adolescent population 13.55%. In conclusion, FSP in children are influenced by age. It is noteworthy that the RFS prevalence of children is lower in comparison to the adult population.  相似文献   

The relevance of media in football coaching: the case of José Mourinho’s leadership approach     

Fernando Ilharco 《Soccer & Society》2019,20(2):307-324

This article examines the leadership approach of the football coach José Mourinho, particularly of the relevance of the media for his top performance at Porto (2002–2004), Chelsea (2004–2007), Inter Milan (2008–2010) and Real Madrid (2010–2013). The perspective from which we analyse the work of Mourinho in that period, and his presence in the media, is based on what science calls the paradigm of complexity. This is a relational perspective which, in this case, means not only focusing upon the actions ‘central’ to the activity in question – the technique, tactics, physical preparation and so on – but, with particular relevance, detail and in an integrated fashion, also focusing on the media and the cultural context in which the activity takes place. Key to the transformational work of José Mourinho is his presence in the media, the managing of fame, the challenges and ambitions of the players, the fans and the general public. At stake is a personification of a global system of significance.  相似文献   

An Analysis of College Choice Information Provided on Graduate Program Websites: Implications for Improving Applicant Diversity in Educational Measurement     

Joseph A. Rios  Jennifer Randall  Marina Donnelly 《Educational Measurement》2019,38(4):67-77

There has long been a concern about the lack of representation of ethnic minorities in the field of educational measurement. As previous research has shown that graduate programs primarily rely on their websites for recruiting efforts, the objective of this study was to conduct a content analysis of all U.S. educational measurement program websites to evaluate the availability of college choice information found to be useful for underrepresented ethnic minority applicants. In terms of program climate, results revealed that less than 10% of programs directly encouraged ethnic minorities to apply or included an antidiscrimination statement with regard to application review on their websites. Moreover, only a few program websites indicated the availability of flexible programming—previously found to be important for underrepresented ethnic minority students—such as part‐time options (16%), evening courses (10%), and online course/program availability (8%). Recommendations for how measurement programs can improve their websites to include desirable college choice information for underrepresented ethnic minority applicants are discussed.  相似文献   

High-Resolution Ultrasonic Imaging of Artworks with Seismic Interferometry for Their Conservation and Restoration     

Deyan Draganov  Jürg Hunziker  Karel Heller  Karin Gutkowski  Fernando Marte 《文物保护研究》2018,63(5):277-291

Artworks are an inseparable part of the cultural heritage of societies and provide us with a unique look at cultural developments through time and space. For the best possible conservation, it is paramount to know the constituent materials, condition, and construction techniques of the objects (e.g. painting on wood, fresco, sculpture). Such information is required not only for the surfaces of the objects, but also for the interiors; in the imaging discipline, this is known as depth imaging. Here, we introduce a new method for non-invasive depth imaging as an alternative to traditional non-invasive methods when the latter cannot be used to obtain the required information. We use ultrasonic transverse-wave transmission measurements and turn them into virtual reflection measurements. We achieve this by applying seismic interferometry with active sources. Obtaining reflection measurements by seismic interferometry allows us to apply an advanced imaging technique – prestack depth migration, as used in seismic exploration – to produce a high-resolution depth image of an object. We apply our method to ultrasonic data recorded on a mockup of a painting on a wooden support. We validate our method by comparing our results with an image from X-ray computed tomography.  相似文献

Development and initial validation of a scale to measure emotional abuse among school children aged 13-15 years in Sri Lanka     

Fernandopulle S  Fernando D 《Child abuse & neglect》2003,27(10):1087-1099

OBJECTIVE: To develop a scale to measure emotional abuse among school children aged 13-15 years in Sri Lanka that can be used in field settings. METHOD: Emotional abuse was defined based on available literature. Review of literature and discussions with a panel identified 85 items indicating abusive behaviors. Content validity and social acceptability were achieved by getting the views of this same panel and parents, respectively. Item analysis and assessment of validity were carried out based on the responses to the draft instrument by 105 children aged 13-15 years attending a school in an urban slum area. The test-retest reliability of the scale was assessed using the responses from 144 students from a different school. Criterion validity was established by comparing the independent assessments of a psychiatrist for the presence or absence of emotional abuse with the respective scores of the children on the scale. RESULTS: The scale developed to assess emotional abuse included 46 items having a Cronbach alpha of .89. The test-retest reliability was .73. A cutoff score of 95 was identified at a sensitivity of 76.9% and a specificity of 51.4%. CONCLUSIONS: A scale that had a satisfactory level of reliability and validity was socially acceptable, which could be used in school settings in Sri Lanka was developed to enable identification of emotional abuse among school children aged 13-15.  相似文献
