Medical teachers' professional development – perceived barriers and opportunities     

Terese Stenfors-Hayes  Maria Weurlander  Lars Owe Dahlgren  Håkan Hult 《Teaching in Higher Education》2013,18(4):399-408

This paper explores medical teachers' perceived barriers and opportunities for educational and professional development. Data has been gathered through 19 semi-structured interviews with participants on a staff development course 1 year after their participation. The analysis shows that most perceived barriers are found on an organisational level, whilst motivation for development is found on an individual level and often related to the notion of teaching as a ‘private business’. However, what some respondents perceive as barriers are by others seen as opportunities. Some of these differences in perception may be explained by self-efficacy beliefs.  相似文献   

Students' perception of university teaching behaviours     

Akhtar Ali  Riaz H. Tariq  J. Topping 《Teaching in Higher Education》2013,18(6):631-647

The purpose of the paper is to explore Students' perception of university teaching behaviours in Pakistan. Three hundred and fifty students from the six public sector Pakistani universities returned questionnaires. Assessment framework, learning activities and instructional strategies emerged from factor analysis as common factors. Students' views on five conceptual variables were also analysed: instructional design, active teaching, learning activities, questioning styles; and assessment framework. University teaching in Pakistan was found to be driven by assessment. This is a matter of concern for all stake holders, including the administration of the universities, teachers, students and the Higher Education Commission. A teaching behaviour paradigm shift is required, switching from knowledge-oriented teaching behaviour focused on successful passage through assessment, to teaching behaviour focused upon the development of transferable skills demanded by external markets.  相似文献   

对爱上瘾还是真爱?     

Mary H.Guindon 《英语沙龙》2013,(2)

Love is an intense feeling that can easily be confused with love addiction.You've been together for a while now.That euphoric (神愉悦的),queasy (令人眩晕的),sign of true love has settled down only slightly and you know this is your one and only love,your heart's desire.  相似文献

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation.  相似文献   

Exercise cardiac power and the risk of heart failure in men: A population-based follow-up study

Background:Little is known about exercise cardiac power(ECP),defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise,on heart failure(HF)risk.We examined the association of ECP and the risk of HF.Methods:This was a population-based cohort study of 2351 men from eastern Finland.The average time to follow-up was 25 years.Participants participated at baseline in an exercise stress test.A total of 313 cases of HF occurred.Results:Men with low ECP(<9.84 mL/mmHg,the lowest quartile)had a 2.37-fold(95%confidence interval(95%CI):1.68-3.35,p<0.0001)hazards ratio of HF as compared with men with high ECP(>13.92 mL/mmHg,the highest quartile),after adjusting for age.Low ECP was associated with a 1.96-fold risk(95%CI:1.38-2.78,p<0.001)of HF after additional adjustment for conventional risk factors.After further adjustment for left ventricular hypertrophy,the results hardly changed(hazards ratio=1.87,95%CI:1.31-2.66,p<0.001).One SD increase in ECP(3.16 mL/mmHg)was associated with a decreased risk of HF by 28%(95%CI:17%-37%).Conclusion:ECP provides a noninvasive and easily available measure from cardiopulmonary exercise tests in predicting HF.However,ECP did not provide additional value over maximal oxygen uptake.  相似文献   

An Integrated Human Information Behavior Research Framework for Information Studies   总被引：1，自引：0，他引：1  

Diane H. Sonnenwald  Mirja Iivonen   《Library & information science research》1999,21(4):429

Human information behavior is emerging as an important component of information studies. As in many emerging research areas, one challenge is to identify important facets of human information behavior and understand how different methods can be best used to research these facets. This paper presents the framework of an approach to designing and synthesizing research studies in human information behavior. The framework emerges from previous research in human information behavior and incorporates Ranganathan's framework for knowledge organization. It proposes that research studies that investigate human information behavior should consider the following facets: personality, matter, energy, space, and time. Personality refers to actors, and in this framework includes participants and their social networks. Matter refers to the target of the action. It includes information and information resources, including services and technology that may provide access to information. Energy is the action itself, including the participants' tasks, processes, and goals. Space is the environment of the action, and includes physical space as well as organizational and sociopolitical contexts. Time is the nonspatial continuum in which actions and events occur; in the framework, time is considered an episode, interval, or eon. Facets that should be investigated and taken into account in a study help guide the selection of the research methods for the study. Furthermore, research results from multiple studies can be synthesized by understanding the relationships among the facets investigated in the different studies.  相似文献   

Stabilization of switched linear singular systems with state reset     

Xiaoqing Xiao  Ju H. Park  Lei Zhou 《Journal of The Franklin Institute》2019,356(1):237-247

This paper investigates the stability and stabilization of switched linear singular systems with state reset at switching instants. Based on the dynamics decomposition of singular subsystems, a sufficient stability condition for the system with the given state reset is obtained. Then, the stabilization problem by state reset is investigated and an algorithm for computing the reset matrices is presented. The obtained results extend some previous works on both singular switched systems and reset control for normal switched systems. Finally, a numerical example is presented to illustrate the effectiveness of the proposed approach.  相似文献   

Institutional complementarities: The origins of experimentation in China’s plug-in electric vehicle industry     

John P. Helveston  Yanmin Wang  Valerie J. Karplus  Erica R.H. Fuchs 《Research Policy》2019,48(1):206-222

A vast literature on technology transitions within industries suggests that early phases of new technologies are marked by periods of intense experimentation, but we know little about the conditions under which these periods emerge. We apply inductive, grounded theory-building techniques to examine what prompts firms to experiment across one emerging technology platform—plug-in electric vehicles (PEVs)—in China. Triangulating annual vehicle make and model sales data from 2003 to 2016 (plus monthly data from 2010 to 2016); 112 English and Mandarin archival documents from industry, academic, and news outlets; and 51 semi-structured interviews with industry, government, and academic stakeholders, we develop four in-depth case studies. We find that in contrast to the innovation trajectories of multinational and Chinese arms of joint venture (JV) firms, independent domestic Chinese firms (those with no history of international JV partnerships) are undertaking significant experimentation across multiple levels—infrastructure, core system, subsystem, and component—of the emerging PEV technology platform. We propose the concept of “institutional complementarities” to describe how interactions among institutions—here the national JV regulation and local market support and subsidies—may have turned regional markets into protected laboratories, extending the incubation periods for independent domestic firm experimentation. While this diverse experimentation may be an important antecedent of technology transition, consolidation induced by national policy standardization or competitive pressure may be required for PEV innovations to scale beyond their early, protected regional markets.  相似文献   

Kawaii Killers and Femme Fatales: A Textual Analysis of Female Characters Signifying Benevolent and Hostile Sexism in Video Games     

Jessica E. Tompkins  Teresa Lynch  Irene I. Van Driel  Niki Fritz 《广播与电子媒介杂志》2020,64(2):236-254

ABSTRACT

Game developers potentially convey socio-cultural values about gender through design choices. This study interpreted the designs of 11 purposively selected female game characters, developed by studios located in the United States and Japan, through the lens of ambivalent sexism. This social psychological theory posits that sexism consists of hostile and benevolent attitudes about women. Two themes emerged across characterizations: bodies as objects, bodies as weapons and (in)dependence. Both consisted of empowering qualities paired with problematic beliefs about women. This analysis contributes to interdisciplinary literature by using an empirical perspective to interpret gender representations in video games.  相似文献
