An exploratory study was carried out to investigate the relative effectiveness of news stories watched on television and news stories read by children. Children aged 10 to 12 (n = 123) either watched five news stories or read print versions of the same news stories. In each condition, half of the children expected a retention test, whereas the other children did not. Results indicated that children who did not expect a retention test learned more from television news than from printed news. Among children who expected a retention test, televised and printed news were recalled about equally well. 相似文献

This paper seeks to highlight the links and discrepancies between three contemporary theoretical fields. The first part is devoted to theories of mind and personal epistemology. Both fields deal with naïve theories relating to the nature of knowledge and can be integrated within the concept of folk epistemology (Kitchener New Ideas Psychol 20:89–105, 2002). We argue that analyzing both domains from a developmental perspective may provide evidence for the origins of epistemological beliefs and the reasons for their evolution. The second part of the paper extends the discussion to the concept of metacognition and to its potential links with the two previously mentioned fields. In the past, theories of mind and metacognition have mainly developed as independent fields, but recent studies have highlighted a possible developmental lineage between them that needs further investigation. As the influence of the procedural component of metacognition (the regulation process) seems obvious in the personal epistemology perspective, we suggest that conducting more in situ studies will enable us to deepen our understanding of the links between the multiple components of the epistemological perspective and the reasons for epistemic change. 相似文献

Changes in the relation between cognitive and metacognitive skills during the acquisition of expertise 总被引:2,自引:0,他引:2

This paper focuses on the transformation of general metacognitive skills of novices into domain-specific regulatory procedures of experts, and the relation of those skills to intelligence. Research has shown that the general metacognitive skills of novices, although partly correlated to intelligence, additionally contribute to learning outcome on top of intelligence. The metacognitive skills of experts appear to be domainspecific and unrelated to intelligence. Two experiments were conducted. The objective of the first experiment was to confirm and generalize these earlier results concerning the relation of intellectual ability, metacognitive skillfulness and learning of novices vs. advanced subjects. The objective of the second experiment was to investigate this relation under different conditions of task complexity. It was hypothesized that advanced subjects would regress to more novice-like behavior under very complex learning conditions (i.e., general metacognitive skills and intelligence would re-appear as combined predictors of learning outcome). On the other hand, low intelligent novices, irrespective of their metacognitive skillfulnes, were expected to fail on very complex problems. Results partly confirmed these hypotheses. Implications for the conditions under which metacognitive experiences should be implemented, are being discussed. 相似文献

Social media systems have encouraged end user participation in the Internet, for the purpose of storing and distributing Internet content, sharing opinions and maintaining relationships. Collaborative tagging allows users to annotate the resulting user-generated content, and enables effective retrieval of otherwise uncategorised data. However, compared to professional web content production, collaborative tagging systems face the challenge that end-users assign tags in an uncontrolled manner, resulting in unsystematic and inconsistent metadata.This paper introduces a framework for the personalization of social media systems. We pinpoint three tasks that would benefit from personalization: collaborative tagging, collaborative browsing and collaborative search. We propose a ranking model for each task that integrates the individual user’s tagging history in the recommendation of tags and content, to align its suggestions to the individual user preferences. We demonstrate on two real data sets that for all three tasks, the personalized ranking should take into account both the user’s own preference and the opinion of others. 相似文献

IntroductionLeukolysis-related pseudohyperkalemia due to preanalytical procedures may lead to erroneous (or absence of) treatment based on an invalid lab test result. We aimed to obtain a leukocyte threshold above which leukolysis-related pseudohyperkalemia becomes clinical relevant. Secondly, temporal dynamics of treatment-induced leukocyte decrease were studied to allow tailored implementation of laboratory information system (LIS) decision rules based on the leukocyte threshold to avoid leukolysis-related pseudohyperkalemia.Materials and methodsPotassium results of AU5811 routine chemistry (Beckman Coulter, Brea, California, USA) and iStat point of care (POC) (Abbott Diagnostics, Chicago, Illinois, USA) analysers were compared, the latter method being insensitive to leukolysis caused by pre-analytical procedures. Potassium results were combined with leukocyte counts obtained using a Cell-Dyn Sapphire haematology analyser (Abbott Diagnostics, Santa Clara, California, USA), resulting in 132 unique data triplets. Regression analysis was performed to establish a leukocyte threshold. The Reference Change Value (√2 x Z x √(CVa2 + CVi2)) was used to calculate maximum allowable difference between routine analyser and POC potassium results (deltamax + 0.58 mmol/L). Temporal analysis on the treatment-induced leukocyte decrease was performed by plotting leukocyte counts in time for all patients above the threshold leukocyte count (N = 41).ResultsEstablished leukocyte threshold was 63 x109/L. Temporal analysis showed leukocyte counts below the threshold within 8 days of treatment for all patients.ConclusionsBased on performed analyses we were able to implement LIS decision rules to reduce pseudohyperkalemia due to preanalytical procedures. This implementation can contribute to a reduction in erroneous (or absence of) treatments in the clinic. 相似文献

The main focus of this case study of a fifth grade teacher observed in 21 lessons is on variability; not the variability of a particular teacher in regard to the average teaching pattern, but the intra-individual variability. The analyses are related to two hypotheses: (1) The teacher's pattern of behavior remains stable whatever he or she is teaching; and (2) The teacher varies his or her behavior according to what is being taught. The data are consistent with the first hypothesis, but not the second one. Although the absolute frequencies of each behavioral category vary a lot across lessons, the content does not appear as a sufficiently explanatory factor. By a factorial analysis of correspondences, the author identified two major kinds of lessons and formulated a new explanatory hypothesis in which teacher planning plays a crucial role. 相似文献

The use of trademark data in innovation studies is still limited because as yet no guidelines exist to ascertain which trademarks relate to innovation. This paper proposes that a branding strategy approach may help to identify innovation related trademarks. Companies use distinctive branding strategies for innovation and these branding strategies have important consequences for the design of new trademarks and their application scope. Based on a sample of Benelux and Community trademarks, we find that trademarks for brand creation relate more often to product innovation. In addition, we find negative effects of a trademark’s industry scope on its relatedness to product innovation, and of a trademark’s geographic scope on its relatedness to service innovation. Our findings bear several key implications for further research towards identifying innovation-related trademarks from a branding strategy perspective. 相似文献

ABSTRACT This study investigated the effects of maturity status on knee extensor torque and vastus lateralis architecture of young soccer players. Thirty-four males aged 13–18 years were divided into two groups: pubescent (PUB, n = 15) and postpubescent (POSP, n = 19). Torque by angle interaction was established for absolute [F(2.649, 84.771) = 9.066, p < 0.05] and relative to body mass [F(2.704, 86.533) = 4.050, p < 0.05] isometric torque with the POSP group showing greater values. Muscle volume torque-angle relationship was similar between groups. Absolute, relative to body mass, and relative to muscle volume concentric and eccentric torque-velocity relationship showed a non-significant interaction but a significant group effect in favour the POSP group for absolute and concentric torque relative to body mass. Torque-angle and torque-velocity relationship normalized by body mass allometric exponents showed a non-significant interactions and group effects. Muscle thickness (3.6 ± 0.6 vs. 3.8 ± 0.6 cm), fascicle length (8.3 ± 1.4 vs. 8.9 ± 1.6 cm) and pennation angle (15.0 ± 2.3 vs. 14.3 ± 3.2 degrees) was similar between PUB and POSP groups, respectively. Maturity status did not show a significant effect on muscle architecture and on isometric and dynamic torques when allometrically normalized. 相似文献

ABSTRACTAmid ongoing disruption, discourse about journalism increasingly emphasizes innovation within the newsroom and the rise of entrepreneurial initiatives outside it. This article uses the concept of interpretive repertoires to explore how students enrolled in journalism programmes in Britain and the Netherlands understand innovation and entrepreneurialism in relation to changing industry circumstances and long-standing conceptualizations of occupational norms and behaviours. We find shared repertoires that embrace technological change, but generally within an acceptance of traditional normative practice. 相似文献
