Reports in a book on randomized trials by Mosteller and Boruch are used as a benchmark. The initiatives have been driven heavily by recent governmental emphasis on ＂evidence based policy＂ in education, criminology, welfare and other sectors. This policy has been backed, in the US at least, by substantial investments in mounting randomized controlled trials to evaluate curriculum packages and programs in grades K-12, crime prevention programs, welfare, and other work. Accelerated growth in randomized trials has entailed cross discipline pre-doctoral and post-doctoral institutes and graduate education programs aimed at enhancing the quality in trial design, execution, and analysis of results. Specific illustrations of graduate education in this area of statistics are taken mainly from experience at the University of Pennsylvania＇s Graduate School of Education and selected other institutions.展开更多

文摘With the common trend of integration and accelerated industrialization-modernization,especially in the context of the current Industrial Revolution 4.0,the South is one of the areas where there are situations and requirements especially for training and research in social sciences in general,sociology in particular.Because,the issue is not only to contribute to the early recovery of the―human resource valley‖(specializing in the South West),facilitating the rapid development of human resources for―investment policy‖and early implementation of the―zoning,planning‖but also by many other economic,social,and cultural issues of the whole region…All have been asked to promote the training and applied research in sociology,especially in specialized sociology to contribute to the linking and promoting the active role of the social sciences with strategic issues and strategies related to the practical development of this land both in the immediate future and in the long run.
文摘This invited paper reviews recent initiatives in teaching about randomized field trials at the graduate level in education research. Reports in a book on randomized trials by Mosteller and Boruch are used as a benchmark. The initiatives have been driven heavily by recent governmental emphasis on ＂evidence based policy＂ in education, criminology, welfare and other sectors. This policy has been backed, in the US at least, by substantial investments in mounting randomized controlled trials to evaluate curriculum packages and programs in grades K-12, crime prevention programs, welfare, and other work. Accelerated growth in randomized trials has entailed cross discipline pre-doctoral and post-doctoral institutes and graduate education programs aimed at enhancing the quality in trial design, execution, and analysis of results. Specific illustrations of graduate education in this area of statistics are taken mainly from experience at the University of Pennsylvania＇s Graduate School of Education and selected other institutions.
文摘A survey of language training centers(LTCs)in Dalian,China was conducted,to ascertain the strengths and weaknesses,or the differentiating factors,of such centers.The survey was undertaken to understand the current landscape of after-school institutes in the region,particularly those that offer training in English as a second/foreign language.The information uncovered by the research is considered beneficial not only to entrepreneurs who may wish to be involved in this industry,but also to college English majors who may wish to teach at an LTC.
文摘Background Stable angina pectoris is a common subtype of coronary heart disease.Patients suffer from chest tightness,chest pain and crushing pain under the inducement of fatigue and emotional agitation.This study aims to investigate the effect of exercise training guidance based on action research on exercise endurance and readmission rate of patients with stable angina pectoris.Methods A retrospective study was conducted on 60 patients with stable angina pectoris due to coronary heart disease admitted to our hospital from February 2020 to November 2023.Patients were divided into a control group of 29 cases(receiving conventional exercise training guidance)and a guidance group of 31 cases(receiving action research-based exercise training guidance).Both groups received continuous training for one month.A comparison was made between the exercise endurance indicators[6-minute walk test distance(6MWT),peak oxygen consumption(peak VO2),anaerobic threshold(AT),exercise duration(ED)],quality of life,and readmission rate within 6 months after intervention in both groups.Results After 1 month of intervention,6MWT,peak VO2,AT and ED were increased in both groups,and those in the guidance group were higher than those in the conventional group(P<0.05).The score of quality of life(The 36-item shot-form health status survey,SF-36)in both groups was increased,and the guidance group scored higher than the conventional group(P<0.05).The readmission rate of patients in the guidance group was 6.45%,which was lower than that in the conventional group(27.59%)(P<0.05).Conclusions The application of action research-based exercise training guidance in patients with stable angina pectoris due to coronary heart disease has significant effects,improving exercise endurance,significantly improving quality of life,and reducing readmission rate,thus having practical value.[S Chin J Cardiol 2024;25(3):162-168]
文摘AIM:To determine the benefits of a 10-wk resistance training programme on cardiovascular health in nonobese and active adolescents.METHODS:This is a pragmatic randomised controlled intervention.The study was carried out in a Hong Kong Government secondary school.Thirty-eight lean and active boys and girls were randomised to either the resistance training group or the control group.Students in the resistance training group received in-school 10-wk supervised resistance training twice per week,with each session lasting 70 min.Main outcome measures taken before and after training included brachial endothelial dependent flow-mediated dilation,body composition,fasting serum lipids,fasting glucose and insulin,high sensitive C-reactive protein,24-h ambulatory blood pressure and aerobic fitness.RESULTS:The only training related change was in endothelial dependent flow-mediated dilation which increased from 8.5%to 9.8%.A main effect of time and an interaction(P<0.005) indicated that this improvement was a result of the 10-wk resistance training.Main effects for time(P<0.05) in a number of anthropometric,metabolic and vascular variables were noted;however,there were no significant interactions indicating the change was more likely an outcome of normal growth and development as opposed to a training effect.CONCLUSION:Ten weeks of resistance training in school appears to have some vascular benefit in active,lean children.
文摘It is imperative that all stakeholders within the research ecosystem take responsibility to improve research integrity and reliability of published research.Based on the unique experiences of a specialist publishing ethics and research integrity team within a major publisher,this article provides insights into the observed trends of misconduct and how those have evolved over time,and addresses key actions needed to improve the interface between researchers,funders,institutions and publishers to collectively improve research integrity on a global scale.
文摘BACKGROUND Case studies(CS)are relevant for the development of theoretical and practical competencies in psychotherapy.Despite rapid progress in the development of methods and principles for establishing CS in the last three decades,research into the aims of CS,especially in training,or how CS are to be conducted is rare.AIM To elucidate the form and methodology of CS,the objectives of CS used in training institutions(TI),and if/how TIs handle therapist allegiance.Also,this preliminary investigation will suggest avenues for further research and attempt to establish certain guidelines.METHODS In order to counteract researcher bias and enlarge the question-pool,a focus group was established.The recorded and transcribed text was analyzed with Mayring’s method of qualitative content analysis,and the generated categories were formulated as questions.The resulting questionnaire with both qualitative and quantitative queries was sent out(after pre-testing)to all 39 Austrian TIs that provide professional psychotherapy training.The answers and text passages received were then also categorized with qualitative content analysis.Data analysis was discussed by a peer group consisting of three psychotherapists trained in differing schools of psychotherapeutic methods.RESULTS 94%of Austrian institutes use CS as part of their psychotherapeutic training.Understanding of the term“case study”is inconsistent and has a wide variety of interpretations.CS serve mainly:(1)For observation of training/progress in therapeutic practice and knowledge/acquisition of the theory specific to each psychotherapeutic school;(2)To improve(self-)reflection capabilities;and(3)To expand theoretical knowledge.Most of the CS written are not accessible for students nor for the research community.More than two thirds of the CS take only the position of the author into account(the client’s position is not described).15.5%of the TIs do not consider researcher or therapist allegiance at all.CONCLUSION A more precise formulation of the term case study is needed in psychotherapeutic training.The training therapists play a key function,as they exemplify and teach how to deal with distorting factors.General guidelines as to how to conduct CS in training institutions would provide more direction to students,increase scientific rigor,and enhance synergistic effects.
