The present study establishes the fact that effective information processing is dependent on the learning techniques one adopts. A sample of 100 students in the age group from 13 to 17 including boys and girls were chosen. They were divided into two groups of control and experimental. To the experimental group, certain specific learning techniques were taught for a period of six months. The same group was tested taking blood samples to study the neuro transmitter serotonin levelshenme before and after adopting learning techniques. Results of the study proved that there is significant relationship between learning techniques and the information processing ability of an individual. 相似文献

Adhesion molecules play a key role in cancer progression and tumorigenesis. Genetic polymorphism of adhesion molecules may alter the normal functioning thereby leading to bladder cancer susceptibility. Hence we aimed to evaluate three SNPs of CD166 gene (CD166rs6437585 C/T, CD166rs10511244 C/T, and CD166rs1157 A/G) in bladder cancer patients and normal controls of North Indian population. A total of 270 healthy controls and 240 confirmed bladder cancer patients were recruited for this study. Three SNPs of CD166 gene viz. CD166rs6437585 C/T, CD166rs10511244 C/T, and CD166rs1157 A/G were selected for this study. CD166rs6437585 C/T and CD166rs10511244 C/T were genotyped by Taqman allelic discrimination assay and CD166rs1157 A/G was genotyped by PCR–RFLP. The statistical analysis was done using the SPSS software, version 16.0 (SPSS, Chicago, IL), and p < 0.05 was considered statistically significant. Haplotypic analysis was done by using SNP analyzer version 1.2A. CD166rs6437585 C/T and CD166rs10511244 C/T showed significant association with reduced risk in bladder cancer while CD166rs1157 A/G showed significant high risk along with association at genotypic and allelic levels. Haplotypic analysis showed 1.8-folds risk in CCG combination, whereas CTA and TCG showed significant association with reduced risk. Further stratification on the basis of smoking, tumor grade/stage and BGC therapy revealed no association of these three polymorphic sites of CD166. Our study suggests that CD166rs6437585 C/T and CD166rs10511244 C/T are predictive for the reduced risk of bladder cancer, whereas CD166rs1157 A/G had shown significant association with high risk of bladder cancer in North Indians. This somehow suggests that CD166rs1157 A/G can be used as a marker for risk prediction of bladder cancer. 相似文献

Environmental occurrence of Aspergillus and other fungal spores are hazardous to humans and animals. They cause a broad spectrum of clinical complications. Contamination of aflatoxins in agri-food and feed due to A. flavus and A. parasiticus result in toxicity in humans and animals. Recent advances in aspergillus genomics and aflatoxin management practices are encouraging to tackle the challenges posed by important aspergillus species. 相似文献

One of the main differences between novice and expert problem solving in physics is that novices mostly construct problem representations from objects and events in the experimental situation, whereas experts construct representations closer to theoretical terms and entities. A main difficulty in physics is in interrelating these two levels, i.e. in modelling. Relatively little research has been done on this problem, most work in AI, psychology and physics education having concentrated on how students use representations in problem solving, rather than on the complex process of how they construct them. We present a study that aims to explore how students construct models for energy storage, transformation and transfers in simple experimental situations involving electricity and mechanics. The study involved detailed analysis of problem solving dialogues produced by pairs of students, and AI modelling of these processes. We present successively more refined models that are capable of generating ideal solutions, solutions for individual students for a single task, then models for individuals across different tasks. The students' construction of energy models can be modelled in terms of the simplest process of modelling — establishing term to term relations between elements of the object/event world and the theory/model world, with underlying linear causal reasoning. Nevertheless, our model is unable to take into account more sophisticated modelling processes in students. In conclusion we therefore describe future work on the development of a new model that could take such processes into account.1. CHENE = CHaîne ENErgetique, or Energy Chain. (In French Chêne also means oak).2. Throughout the rest of the paper we use the following simple notation in order to avoid possible confusion between modelling as a process performed by the students, in the domain of physics, and AI modelling of the former modelling process: students' modelling in physics = modelling

.3. It has not been necessary to use more sophisticated strategies at the stage of our work reported here. The next system, modelCHENE, will directly address this issue.4. Note that what we refer to in this context as problem solving may in another context be viewed as construction of a qualitative representation for subsequent quantitative problem solving.5. The protocols indicate that students use this as a kind of anchor in their reasoning-some students returning to it in order to resolve impasses. As the current problem solver provides no mechanism for handling impasses we cannot model the reuse of information in any meaningful way.6. We are grateful to an anonymous reviewer for this example.7. This provides the minimum distinction for our initial needs.8. Though there is a difficult step in deciding that the moving object really is the last unassigned object-since that requires setting aside any need to assign roles to, for example, connecting strings etc.9. At the moment we have to provide psCHENE with slightly different rulesets: providing rules with priorities would be more convenient. 相似文献

Since their inception in 1993 at an Australian university, the workshop tutorials in physics have evolved and grown beyond the initiating department. In this paper, we adopt an interpretive perspective to: (i) reflect on why the tutorials continue to be successful; (ii) use models from literature to understand that success; and (iii) abstract key features that can inform scholarly inquiry into teaching and learning in higher education in other contexts and discipline areas. Practitioner (action) research and design‐based research not only provide useful methodological frameworks that support the success of the workshop tutorials, but they also offer a worthwhile methodological strategy for fostering scholarly inquiry into university teaching and student learning. 相似文献

Arts integration research has focused on documenting how the teaching of specific art forms can be integrated with ‘core’ academic subject matters (e.g. science, mathematics and literacy). However, the question of how the teaching of multiple art forms themselves can be integrated in schools remains to be explored by educational researchers. This paper draws on data collected at a secondary school in Singapore. The case study analyses how three art teachers, using the idea of ‘space’ as organizing theme, implemented a module of instruction that connected concepts and processes from a variety of art forms (including dance, music, drama and visual arts). We present evidence from curriculum materials, lesson plans, student–teacher classroom interactions and students’ productions. Students were able to reflect upon the importance of space within the arts, analyse the points of convergence and divergence among several art forms, experiment with space and create their own interdisciplinary performances. Our ultimate aim is to provide insights that might inspire art teachers in designing instructional units focused on ‘big ideas’. We suggest that allowing more curricular freedom and providing teachers with adequate structures for interdisciplinary collaboration are key to achieving meaningful levels of integration. 相似文献

Hyperhomocysteinemia has been considered an independent risk factor in the development of stroke. The present study was undertaken
to evaluate serum homocysteine levels in patients with cerebrovascular accidents among the Manipuri population and to compare
with the normal cases. Ninety-three cerebrovascular accident cases admitted in the hospital were enrolled for the study and
twenty-seven age and sex matched individuals free from cerebrovascular diseases were taken as control group. Serum homocysteine
levels were estimated by ELISA method using Axis homocysteine EIA kit manufactured by Ranbaxy Diagnostic Ltd. India. The finding
suggests that hyperhomocysteinemia is associated with cerebrovascular accident with male preponderance, which increases with
advancing age. However, whether hyperhomocysteinemia is the cause or the result of cerebrovascular accidents needs further
investigations. 相似文献

Co-opetition between giants: Collaboration with competitors for technological innovation 总被引：6，自引：0，他引：6

We investigate why and how co-opetition (simultaneous pursuit of collaboration and competition) between large firms occurs, evolves, and impacts the participating firms and the industry. We develop a multi-level conceptual framework by combining literature-based conceptual arguments and insights from an in-depth study of an exemplar case of co-opetition between Samsung Electronics and Sony Corporation. Our study demonstrates that co-opetition is challenging yet very helpful for firms to address major technological challenges, to create benefits for partnering firms, and to advance technological innovation. We also show that co-opetition between giants causes subsequent co-opetition among other firms and results in advanced technological development. Moreover, co-opetition capabilities of firms play an important role in enhancing common benefits as well as in gaining proportionately larger share of the benefits. 相似文献
