Medical educators: How they define themselves - Results of an international web survey.

BACKGROUND Little is known about medical educators' self-definition. AIMS The aim of this study is to survey an international community of medical educators focusing on the medical educators' self-definition. METHODS Within a comprehensive, web-based survey, an open question on the participants' views of how they would define a "medical educator" was sent to 2200 persons on the mailing list of the Association for Medical Education in Europe. The free text definitions were analysed using qualitative thematic analysis. RESULTS Of the, 200 medical educators invited to participate, 685 (31.1%) provided a definition of a "medical educator". The qualitative analysis of the free text definitions revealed that medical educators defined themselves in 13 roles, primarily as "Professional Expert", "Facilitator", "Information Provider", "Enthusiast", "Faculty Developer", "Mentor", "Undergraduate and Postgraduate Trainer", "Curriculum Developer", "Assessor and Assessment Creator", and "Researcher". CONCLUSIONS Our survey revealed that medical educators predominantly define themselves as "Professional Experts" and identified 12 further self-defined roles of a medical educator, several of which not to have been reported previously. The results can be used to further the understanding of our professional identity.

Does the use of mobile devices (tablets and smartphones) affect survey quality and choice behaviour in web surveys?

Web surveys are becoming increasingly popular in survey research including stated preference surveys. Compared with face-to-face, telephone and mail surveys, web surveys may contain a different and new source of measurement error and bias: the type of device that respondents use to answer the survey questions. This is the first study that tests whether the use of mobile devices, tablets or smartphones, affects survey characteristics and stated preferences in a web-based choice experiment. The web survey on expanding renewable energy production in Germany was carried out with 3182 respondents, of which 12% used a mobile device. Propensity score matching is used to account for selection bias in the use of mobile devices for survey completion. We find that mobile device users spent more time than desktop/laptop users to answer the survey. Yet, desktop/laptop users and mobile device users do not differ in acquiescence tendency as an indicator of extreme response patterns. For mobile device users only, we find a negative correlation between screen size and interview length and a positive correlation between screen size and acquiescence tendency. In the choice experiment data, we do not find significant differences in the tendency to choose the status quo option and scale between both subsamples. However, some of the estimates of implicit prices differ, albeit not in a unidirectional fashion. Model results for mobile device users indicate a U-shaped relationship between error variance and screen size. Together, the results suggest that using mobile devices is not detrimental to survey quality.

The impact of installer business models on the uptake of residential microgeneration in the UK: Evidence from a nation-wide survey

This paper arises from a doctoral thesis comparing the impact of alternative installer business models on the rate at which microgeneration is taken up in homes and installation standards across the UK. The paper presents the results of the first large-scale academic survey of businesses certified to install residential microgeneration. The aim is to systematically capture those characteristics which define the business model of each surveyed company, and relate these to the number, location and type of technologies that they install, and the quality of these installations. The methodology comprised a pilot web survey of 235 certified installer businesses, which was carried out in June last year and achieved a response rate of 30%. Following optimisation of the design, the main web survey was emailed to over 2000 businesses between October and December 2011, with 317 valid responses received. The survey is being complemented during summer 2012 by semi-structured interviews with a representative sample of installers who completed the main survey. The survey results are currently being analysed. The early results indicate an emerging and volatile market where solar PV, solar hot water and air source heat pumps are the dominant technologies. Three quarters of respondents are founders of their installer business, while only 22 businesses are owned by another company. Over half of the 317 businesses have five employees or less, while 166 businesses are no more than four years old. In addition, half of the businesses stated that 100% of their employees work on microgeneration-related activities. 85% of the surveyed companies have only one business location in the UK. A third of the businesses are based either in the South West or South East regions of England. This paper outlines the interim results of the survey combined with the outcomes from additional interviews with installers to date. The research identifies some of the business models underpinning microgeneration installers and some of the ways in which installer business models impact on the rate and standards of microgeneration uptake. A tentative conclusion is that installer business models are profoundly dependent on the levels and timing of support from the UK Feed-in Tariffs and Renewable Heat Incentive.

Reaching the invisible : overcoming sampling barriers in GLB research via web surveys

Sampling is fundamental to the credibility of any empirical investigation, and this is no different for the area of Gay, Lesbian and Bisexual (GLB) research. In fact, it would not be an overstatement to say that publication of GLB research into high quality and mainstream journals has been limited in part because of sampling issues. The purpose of this paper is to raise awareness of the unique sampling problems posed by GLB resaerch and to offer solutions to these through the use of web surveys and recruitment strategies. In particular, we provide data which show that, contrary to voiced concerns, when employed with a rigorous recruitment strategy, web surveys increase rather than reduce sampling coverage. Further, we provide evidence that the web survey technique can yield data of comparable quality to that obtained with a hard-copy survey. The paper concludes with strategies researchers can adopt to overcome barriers in obtaining a diverse GLB sample.

Patterns of Ecstasy Use and Associated Harm: Results of a Brazilian Online Survey

The aim of this study was to gather information about ecstasy users in Brazil, particularly on issues related to risks associated to the use of the drug, so as to offer a basis to prevention projects. A total of 1,140 Brazilian ecstasy users answered an online questionnaire from August 2004 to February 2005. Participants were predominantly young single heterosexual well-educated males from upper economical classes. A categorical regression with optimal scaling (CATREG) was performed to identify the risks associated with ecstasy use. ""Pills taken in life"" had a significant correlation with every investigated risk, particularly ecstasy dependence, unsafe sex, and polydrug use. ""Gender,"" ""sexual orientation,"" and ""socioeconomic class"" were not predictive of risk behavior. The Internet proved to be a useful tool for data collection. Given the recent increase in ecstasy availability in Brazil, a first prevention campaign directed toward the drug is urgent. At least in a preliminary Brazilian intervention, the campaign must be conducted at night leisure places, mainly frequented by youngsters from upper socioeconomic classes. The results do not call for information material with specific targets, such as gender or sexual orientation. The study`s limitations have been noted.

Does the Use of Mobile Devices (Tablets and Smartphones) Affect Stated Choice Behavior in Web Surveys? An Application to Environmental Valuation

Web surveys are becoming increasingly popular in survey research. Compared with face-to-face, telephone and mail surveys, web surveys may contain a different and new source of measurement error and bias: the type of device that respondents use to answer the survey questions. To the best of our knowledge, this is the first study that tests whether the use of mobile devices affects survey characteristics and stated preferences in a web-based choice experiment. The web survey was carried out in Germany with 3,400 respondents, of which 12 per cent used a mobile device (i.e. tablet or smartphone), and comprised a stated choice experiment on externalities of renewable energy production using wind, solar and biomass. Our main finding is that survey characteristics such as interview length and acquiescence tendency are affected by the device used. In contrast to what might be expected, we find that, compared with respondents using desktop computers and laptops, mobile device users spent more time to answer the survey and are less likely to be prone to acquiescence bias. In the choice experiment, mobile device users tended to be more consistent in their stated choices, and there are differences in willingness to pay between both subsamples.

Common values in assessing health outcomes from disease and injury: Disability weights measurement study for the Global Burden of Disease Study 2010

BACKGROUND Measurement of the global burden of disease with disability-adjusted life-years (DALYs) requires disability weights that quantify health losses for all non-fatal consequences of disease and injury. There has been extensive debate about a range of conceptual and methodological issues concerning the definition and measurement of these weights. Our primary objective was a comprehensive re-estimation of disability weights for the Global Burden of Disease Study 2010 through a large-scale empirical investigation in which judgments about health losses associated with many causes of disease and injury were elicited from the general public in diverse communities through a new, standardised approach. METHODS We surveyed respondents in two ways: household surveys of adults aged 18 years or older (face-to-face interviews in Bangladesh, Indonesia, Peru, and Tanzania; telephone interviews in the USA) between Oct 28, 2009, and June 23, 2010; and an open-access web-based survey between July 26, 2010, and May 16, 2011. The surveys used paired comparison questions, in which respondents considered two hypothetical individuals with different, randomly selected health states and indicated which person they regarded as healthier. The web survey added questions about population health equivalence, which compared the overall health benefits of different life-saving or disease-prevention programmes. We analysed paired comparison responses with probit regression analysis on all 220 unique states in the study. We used results from the population health equivalence responses to anchor the results from the paired comparisons on the disability weight scale from 0 (implying no loss of health) to 1 (implying a health loss equivalent to death). Additionally, we compared new disability weights with those used in WHO's most recent update of the Global Burden of Disease Study for 2004. FINDINGS 13,902 individuals participated in household surveys and 16,328 in the web survey. Analysis of paired comparison responses indicated a high degree of consistency across surveys: correlations between individual survey results and results from analysis of the pooled dataset were 0·9 or higher in all surveys except in Bangladesh (r=0·75). Most of the 220 disability weights were located on the mild end of the severity scale, with 58 (26%) having weights below 0·05. Five (11%) states had weights below 0·01, such as mild anaemia, mild hearing or vision loss, and secondary infertility. The health states with the highest disability weights were acute schizophrenia (0·76) and severe multiple sclerosis (0·71). We identified a broad pattern of agreement between the old and new weights (r=0·70), particularly in the moderate-to-severe range. However, in the mild range below 0·2, many states had significantly lower weights in our study than previously. INTERPRETATION This study represents the most extensive empirical effort as yet to measure disability weights. By contrast with the popular hypothesis that disability assessments vary widely across samples with different cultural environments, we have reported strong evidence of highly consistent results.

Democracia eletrônica para quem? : Quem são, o que querem e como os cidadãos avaliam o portal da Câmara dos Deputados

A dissertação busca responder em que medida todas as possibilidades de interação ofertadas pelo Portal da Câmara dos Deputados atendem às necessidades de interação política dos cidadãos que utilizam estes novos canais. Quem são os usuários destas novas ferramentas? Qual a avaliação que eles fazem destes novos canais? Qual é a opinião deles sobre as possibilidades de participação eletrônica? O principal aspecto teórico abordado nesta dissertação é a seguinte discussão: a internet replica formas de participação tradicionais ou é realmente capaz de fazer com que mais cidadãos, incluindo aqueles que estão alheios e desinteressados, participem? Essas questões foram direcionadas ao Portal da Câmara dos Deputados do Brasil, que, ao longo dos últimos anos, soube adaptar-se e promover um espaço de amplo acesso a informações legislativas, com capacidade de contato e interação entre o cidadão e o seu representante e é considerado, atualmente, o melhor portal legislativo da América do Sul. A dissertação utilizou duas metodologias distintas. A primeira consistiu em analisar as estatísticas de acesso ao Portal, identificando assim os padrões de acesso: os sites de referência e os caminhos de busca através dos quais se chega ao Portal. A segunda consistiu na condução de um Web Survey para coletar a opinião dos usuários. O questionário aplicado teve como objetivo coletar avaliações das ferramentas disponibilizadas pelo Portal, identificar o perfil dos usuários e compreender-lhes o comportamento político no mundo off-line. Um dos principais achados é o de que a Democracia Eletrônica desenvolvida pelo Portal da Câmara dos Deputados tem servido mais aos profissionais da política que ao cidadão comum. Mas, mesmo assim, o cidadão comum, interessado em buscar participação, contato e interação com os atores políticos, está procurando essas ferramentas on-line. Palavras chaves: Democracia Eletrônica, Câmara dos Deputados, pesquisa on-line, estatísticas de acesso.

SPHERE: Stormont Parliamentary Hansards: Embedded in Research and Education

SPHERE (Stormont Parliamentary Hansards: Embedded in Research and Education) was a JISC-funded project based at King’s College, London and Queen’s University, Belfast, working in Partnership with the Northern Ireland Assembly Library, and the NIA Official Report (Hansard). Its purpose was to assess the use, value and impact of The Stormont Papers digital resource, and to use the results of this assessment to make recommendations for a series of practical approaches to embed the resource within teaching, learning and research among the wider user community. The project began in November 2010 and was concluded in April 2010.

An Exploration of Political Consciousness Amongst Final Year Nursing Students in Northern Ireland

Context and background
Historically nurses perceive politics and nursing as being at odds with the caring image, synonymous with nurses (Salvage, 1985). Furthermore the concept of the ‘politics of nursing’ lacks clear conceptual clarity (Hewison, 1994). This concept ranges across a continuum from political interest to participation or engagement (Rains et al, 2001). It is often argued political interest tends to be equated with knowledge/ involvement in health policy development and nurse education can foster political consciousness, through political socialization (Brown, 1996). But despite the World Health Organization (WHO, 2002) urging this involvement, nurses globally are largely absent from the political and policy making arena. What influences nurse’s political socialization and the development of a political consciousness is not clearly identified or known, although many commentators suggest the undergraduate educational environment, plays an important role (Hanley, 1987, Winter, 1991).     

AIM
The aim of this study was to explore third year nursing student’s perceptions of politics in nursing, in the context of Northern Ireland. A number of hypotheses were tested examining the relationship between age, prior educational attainment and political interest and attitudes.  

Research methodology
A cross sectional research design was used and the data was collected using a short anonymous self-completion web survey (Bryman, 2012). The sample was a convenience sample of one cohort of final year adult nursing students (n154) in one Northern Irish university, with a 42% response rate. Data was analyzed using SPSS.

Key findings and conclusions
The results revealed 55% of students were very/fairly interested in politics, with 6% reporting no interest in politics. 85% of students were registered to vote, but only 48% voted in the 2010 N Ireland Assembly election.   
Recommend inclusion of a unit of study incorporating innovative teaching methods related to politics and health related policy, in the undergraduate nursing programme.

Pratiques d’individualisation en enseignement primaire au Québec visant à faciliter l’intégration des élèves handicapés ou des élèves en difficulté au programme de formation générale

Au Québec, des ressources considérables sont investies pour assurer la réussite scolaire des élèves handicapés et en difficulté, tant au plan des apprentissages, de la socialisation que de la qualification. Pour des raisons évoquées d’équité et d’accès à la formation générale, les politiques éducatives privilégient l’intégration de ces élèves en classe ordinaire (Ministère de l'Éducation, 2008; Ministère de l'Éducation du Québec, 1999, 2004a). Ces politiques appellent de profonds changements dans l’organisation scolaire et conduisent inévitablement les enseignants à adopter des pratiques d’individualisation de leur enseignement. En dépit de l’importance de l’individualisation de l’enseignement pour favoriser la réussite des élèves intégrés, les pratiques pédagogiques mises en œuvre par les enseignants québécois demeurent méconnues. Cette étude vise à obtenir un portrait de ces pratiques. Plus spécifiquement, cette étude vise à obtenir des données sur la fréquence d’utilisation de certaines pratiques, à étudier leur compréhension conceptuelle et appliquée par les enseignants, ainsi qu’à identifier des facteurs personnels et organisationnels pouvant expliquer les différences entre les enseignants. Sur la base de la littérature disponible, une typologie des pratiques d’individualisation a été produite, regroupant quatre pratiques : la différenciation pédagogique, l’enseignement de stratégies, l’accommodation et la modification. Puis, un questionnaire élaboré aux fins de cette étude, permettant d’évaluer empiriquement la prégnance de ces quatre pratiques, a été rempli par 138 enseignants provenant de 35 commissions scolaires du Québec. Parmi ces enseignants, treize ont été sélectionnés et interviewés sur la base des exemples de leurs pratiques mentionnées dans les questions ouvertes du sondage. Fondée sur un devis mixte de type concourant et imbriqué (Creswell, 2003), cette recherche combine une stratégie d’analyse quantitative des données issues du questionnaire à des analyses de contenu des entrevues, de nature qualitative. Les résultats convergent vers trois niveaux de prise en charge de l’hétérogénéité en classe: nuancée, mécanique et réactive. Seuls les enseignants qui ont une prise en charge nuancée démontrent une compréhension et une utilisation des pratiques conformes au cadre conceptuel. Suivant cette hypothèse formulée à partir des données d’entrevue, les résultats d’une ANOVA ont permis de conclure que le tiers des répondants au sondage (n=41) utilisant le plus fréquemment la différenciation pédagogique fait une utilisation significativement peu fréquente de la pratique de la modification. Enfin, des analyses de régression ont révélé que parmi les autres facteurs prédisant l’utilisation des pratiques se trouvent la participation à des activités de formation continue, le niveau d’enseignement, le nombre d’élèves dans le groupe et le nombre d’élèves en difficulté avec des plans d’intervention. Les résultats de cette recherche indiquent un niveau de connaissance inégal des pratiques étudiées chez les enseignants, ainsi qu’une mise en œuvre déficiente des ressources nécessaires à l’intégration scolaire des élèves handicapés ou en difficulté.

Phénomène de biohype dans des articles scientifiques rapportant des résultats issus de recherches cliniques en nutrigénétique/nutrigénomique : caractérisation et perception des chercheurs

Le développement de la nutrigénétique/nutrigénomique (NGx) a suscité de nombreuses attentes puisque les retombées qui lui sont associées s’avèrent potentiellement bénéfiques autant pour les individus en santé que pour les individus malades. De grandes attentes avaient également été associées au Projet de décryptage du Génome Humain (PGH). Aujourd’hui, seules quelques attentes de celles envisagées se sont concrétisées. Le PGH a donc évolué dans un contexte marqué par du biohype, soit la promotion d’attentes exagérées, voir irréalistes. Étant donné l’importance des attentes associées avec le développement de la NGx et des limites méthodologiques auxquelles fait encore face la recherche clinique conduite dans ce domaine, l’objectif principal de cette thèse est de déterminer si les publications scientifiques rapportant des résultats de recherches cliniques effectuées en NGx contribuent à l’émergence d’un phénomène de biohype. Plus spécifiquement, il s’agira également de documenter la perception des chercheurs oeuvrant dans le domaine de la NGx du phénomène de biohype, d’identifier certains facteurs qui pourraient expliquer son émergence dans la littérature scientifique propre à ce domaine et de proposer des pistes d’actions pour limiter les risques associés à ce phénomène. Nous avons tout d’abord procédé à une analyse documentaire d’articles scientifiques rapportant des résultats issus de recherches cliniques en NGx. Celle-ci nous a révélé que plusieurs bénéfices étaient promus dans cette littérature alors même que les limites méthodologiques n’étaient pas d’emblée présentées et discutées. Cette observation nous portait à croire que ces bénéfices étant potentiellement prématurés. Nous avons ensuite voulu valider notre constat auprès des chercheurs œuvrant principalement dans le domaine de la NGx. Cette enquête nous a permis de constater que les chercheurs étaient généralement en accord avec les bénéfices que nous avons recensés dans les articles scientifiques. Toutefois, ils n’envisageaient pas leur concrétisation à moyen terme. Par ailleurs, cette enquête nous a également révélé que les limitations méthodologiques actuellement rencontrées dans la conduite de recherches cliniques soulevaient des doutes quant à la faisabilité des bénéfices promut dans les articles scientifiques. Ces données viennent confirmer notre observation à savoir qu’un phénomène de biohype serait réellement en émergence dans les articles scientifiques rapportant des résultats de recherches cliniques en NGx. Outre des informations concernant les publics ciblés par les chercheurs et les éléments que doivent contenir un article scientifique, cette enquête nous a également aidés à mieux comprendre les avantages associés à la promotion de bénéfices. Selon la majorité des chercheurs interrogés, la promotion de bénéfices dans un article scientifique augmenterait les chances d’un manuscrit d’être publié et favoriserait la continuité du financement du domaine de recherche. Cette activité étant caractérisée par un environnement compétitif, la promotion de bénéfices semble être une avenue à envisager pour se démarquer. Quoique la promotion de bénéfices prématurés ou exagérés ne soit pas considérée comme de l’inconduite scientifique, elle peut causer entre autres un affaiblissement du sentiment de confiance entre le public et les chercheurs et ultimement, contrevenir à la continuité d’une saine activité de recherche. À la lumière de ces données, nous croyons qu’une des stratégies qui permettrait de prévenir l’apparition des risques associés au phénomène de biohype serait de sensibiliser les chercheurs et les éditeurs de journaux scientifiques à ces derniers. Plus particulièrement, nous encourageons l’intégration de lignes directrices portant sur la gestion du biohype dans les codes de conduites qui ont été mis en place pour favoriser les bonnes pratiques en recherche.
