Is Standard Quantum Mechanics Technologically Inadequate?     

Muller  F. A.; Seevinck  M. P. 《The British journal for the philosophy of science》2007,58(3):595-604

In a recent issue of this journal, P.E. Vermaas ([2005]) claimsto have demonstrated that standard quantum mechanics is technologicallyinadequate in that it violates the ‘technical functionscondition’. We argue that this claim is false becausebased on a ‘narrow’ interpretation of this technicalfunctions condition that Vermaas can only accept on pain ofcontradiction. We also argue that if, in order to avoid thiscontradiction, the technical functions condition is interpreted‘widely’ rather than ‘narrowly’, thenVermaas, argument for his claim collapses. The conclusion isthat Vermaas' claim that standard quantum mechanics is technologicallyinadequate evaporates.

Physico-chemical characterization of a farmland affected by wastewater in relation to heavy metals   总被引：1，自引：0，他引：1  

Emmanuel U. ONWEREMADU 《浙江大学学报(A卷英文版)》2008,9(3):366-372

This study investigated selected properties of soils affected by wastewater and its relationship with some heavy metals A free survey technique involving target sampling was used in siting soil profile pits. Soil samples were collected based on horizon differentiation and analyzed using routine and special analytical techniques. Soil data were subjected to correlation analysis using SAS program. Results show that all heavy metals studied had values above critical limits in the polluted soils using known standards and that these biotoxic metals decreased with soil depths. Highly significant （P=0.01 and 0.05） relationships were established between investigated heavy metals and some soil properties, especially soil pH and organic matter. Further studies involving more edaphic properties, biotoxic metals and their bioaccessibility in crops growing on wastewater soils will surely enhance knowledge and management of these highly anthropogenically influenced soils of the study site.  相似文献

Running for your life: A review of physical activity and cardiovascular disease risk reduction in individuals with schizophrenia     

Claire Chalfoun  Antony D. Karelis  Emmanuel Stip 《Journal of sports sciences》2016,34(16):1500-1515

Individuals with schizophrenia have a greater risk for cardiometabolic risk factors (e.g. central obesity, insulin resistance, hypertension and dyslipidaemia), cardiovascular diseases and mortality. This risky profile may be explained by the adverse effects of antipsychotic medications and an unhealthy lifestyle (e.g. smoking, poor nutrition and low physical activity). In the general population, physical activity has been shown to be the optimal strategy to improve both cardiometabolic parameters and cardiorespiratory fitness levels. Accordingly, an emerging literature of non-pharmacological interventions (e.g. cognitive behavioural therapy, diet and physical activity) has been studied in individuals with schizophrenia. Therefore, the purpose of this review was 1) to conduct a critical literature review of non-pharmacological interventions that included some kind of physical activity (including supervised and unsupervised exercise training) and target cardiometabolic risk factors in individuals with schizophrenia. 2) To describe the contribution of physical activity alone by reviewing trials of supervised exercise training programmes only. A literature review via systematic keyword search for publications in Medline, PubMed, Embase and PsycINFO was performed. Many non-pharmacological interventions are efficient in reducing cardiovascular disease risk factors when combined with physical activity. Supervised physical activity has been successful in decreasing cardiovascular disease risk, and aerobic interval training appears to provide more benefits by specifically targeting cardiorespiratory fitness levels. In conclusion, physical activity is an effective strategy for addressing cardiovascular disease risk in individuals with schizophrenia. Long-term studies are needed to evaluate the feasibility and impact of exercise training programmes in individuals with schizophrenia.  相似文献   

Three-dimensional kinematics of competitive and recreational cyclists across different workloads during cycling     

Rodrigo R. Bini  Frederico Dagnese  Emmanuel Rocha  Mateus C. Silveira  Felipe P. Carpes  Carlos B. Mota 《European Journal of Sport Science》2016,16(5):553-559

Although the link between sagittal plane motion and exercise intensity has been highlighted, no study assessed if different workloads lead to changes in three-dimensional cycling kinematics. This study compared three-dimensional joint and segment kinematics between competitive and recreational road cyclists across different workloads. Twenty-four road male cyclists (12 competitive and 12 recreational) underwent an incremental workload test to determine aerobic peak power output. In a following session, cyclists performed four trials at sub-maximal workloads (65, 75, 85 and 95% of their aerobic peak power output) at 90?rpm of pedalling cadence. Mean hip adduction, thigh rotation, shank rotation, pelvis inclination (latero-lateral and anterior–posterior), spine inclination and rotation were computed at the power section of the crank cycle (12 o'clock to 6 o'clock crank positions) using three-dimensional kinematics. Greater lateral spine inclination (p?p?p?相似文献   

The Growth of Knowledge and the Discursive Gap     

Rob Moore  Johan Muller 《British Journal of Sociology of Education》2002,23(4):627-637

This article raises the question of the character of Bernstein's theory. It draws upon a set of key concepts elaborated in some of his later papers, although we suggest that it is possible to discern the origins of these ideas in much earlier work. In the first section, Bernstein's diagnosis of the sociology of education as a horizontal knowledge structure with a weak grammar is discussed and an apparent paradox identified: if the sociology of education has this form, how can we account for Bernstein's own theory? The remainder of the paper uses the case of Bernstein's own work as a way of exploring the conditions for knowledge growth in sociology as a vertical knowledge structure with a strong grammar.  相似文献   

Collaborative Amateur Production of Educational Videos,which are Viewed on Mobiles: Addressing Poor Technical Resources for Nigerian Creative Arts Academics     

Anne Chick  Emmanuel Etsename 《The International Journal of Art & Design Education》2019,38(1):110-124

This research was a co‐creation and co‐assessment exercise between the researchers, participating printmaking and weaving academics and their students in a Nigerian university. The poor technical resources and increasingly large student groups in the design department, which severely hampers the delivery of an effective education, were addressed. The academics were supported to learn how to create their own instructional videos for their students, demonstrating identified designer‐maker skills and how to use required equipment. These academics are now empowered and have the knowledge to produce their own instructional videos without professional assistance. This is also irrespective of their previous experiences of using video equipment and developing video content.  相似文献
