The potential utility of an online dental research network from the operspectives of clinicians, researchers, and policy makers /

Makansi, Nora Nader. January 2007 (has links)
Background. An online research network was set up among 11 dentists and 2 researchers in Montreal to test the feasibility of data collection over one year. Objectives. We evaluated the pilot participants' experiences and their perspectives regarding its potential utility. Methods. One-on-one qualitative interviews with 4 researchers, 4 dentists, and 3 policy makers. Interviews were recorded on audiotape and transcribed for coding and interpretation. Results. Although feasibility of data collection was evident in the pilot results; qualitative data revealed the limitations of the pilot, the unmet expectations, and the lack of impact of research findings. In terms of potential utility; the participants expressed interest in research, online communication and continuing education. Qualitative analysis revealed differences in perspectives and shared interests among the participants. Conclusion. An online research network can reduce the gap between research and practice. However, to attract participants, it must consider the needs and expectations of those involved.

Oral health beliefs and dental health care-seeking behaviors among Chinese immigrants

Dong, Mei, 1966- January 2006 (has links)
Understanding culturally related health values and identifying ethnically specific health seeking pathways can help health care providers supply culturally competent services and enhance cooperation with patients of different backgrounds. Cultural competency training, notably through cultural awareness courses, promotes understanding of the impact of social factors on illness and thus prepares medical and dental students to better serve their patients. Cultural awareness can also help preventive health programs fit community needs and cultural contexts. / Despite the fact that Chinese immigrants are the fastest growing ethnic minority in North America, few studies have been published on their beliefs and health-seeking behaviours following immigration. We thus lack information on how Chinese immigrants regard dental health and manage their dental problems. Objective. The aims of this study were to explore how oral illness is viewed by Chinese immigrants in Montreal, Canada and how they manage dental problems. Methods. We conducted a qualitative research study based on semi-structured, one-on-one interviews and thematic analyses of the transcribed interviews. Twelve adult Montreal Chinese immigrants with a high level of education participated in the study. / Results. Chinese immigrants in Montreal have a good understanding of dental caries in terms of its etiology, process, and ways to prevent and treat it. It thus seems that there is no major cultural barrier between this type of immigrant and oral health care professionals in regard to dental caries. However, we also observed that traditional beliefs and medications coexist with scientific dental knowledge and professional treatments concerning problems such as gingival swelling, gingival bleeding, and bad breath. In the case of gingival swelling, for instance, participants identified etiological factors that referred to both cultures: local factors referred to oral hygiene and were related to scientific culture, whereas general factors referred to traditional knowledge ("internal fire"). Chinese immigrants' dental health seeking pathways include self-treatment, consulting a dentist in Canada or in China during a return visit, and obtaining Chinese traditional medicine. The dental health seeking pathways varied depending on the circumstances. For dental caries and other acute diseases such as toothache, Chinese immigrants prefer to consult a dentist. For chronic diseases, some of them rely on self-treatment or an alter-native treatment such as traditional Chinese medicine. The language barrier, financial problems and lack of trust are the main factors affecting Chinese immigrants' access to dental care services in Canada. Former bad medical or dental experience among Chinese immigrants causes a loss of trust in Western medicine and dentistry and influences the decision to seek alternative treatments. / Conclusion. This study suggests that, in order to facilitate dentist-patient communication; oral health professionals should be informed of immigrants' representation of oral health and illness, and that Chinese immigrants should be provided with basic scientific knowledge.

Access to dental care in individuals with Down Syndrome living with their families compared to those not living with their families

Taherinejad, Farahnaz. January 2006 (has links)
Objective. To evaluate access to dental care for individuals with Down syndrome living with their families, as compared to those not living with families. Methods. A cross-sectional, observational study design was used. Data were collected through a questionnaire sent to the 2327 members of the Canadian Down Syndrome Society. Bivariate and multivariate analyses were performed to investigate the association between place of residence and a variety of indicators of access to dental care. Result. In the multivariate stage of analysis, after adjusting for possible confounders, significant association between place of residence and two dependent variables, indicated that individuals with DS living with their families had approximately twice the odds for ever had a filling, (95% CI, 1.0-3.8), and they had approximately one third odds for ever had extractions, compared to individuals with DS living elsewhere (95% CI, 0.1-0.7). Conclusion. These observations suggest that Canadians with DS living at home receiving different dental care compared to those living elsewhere.

Cognitive Science: комплексный подход : магистерская диссертация / Cognitive Science: an integrated approach

Плинер, А. А., Pliner, A. A. January 2015 (has links)
Master's thesis of Pliner A.A. "Cognitive Science: an integrated approach" is devoted to the study of cognitive science as a set of scientific research in various fields of philosophy, psychology, artificial intelligence, linguistics, united by a common research interest in the issue of knowledge. The emergence of interest in cognitive science could attributed to the middle of the XX century and related to the work of such thinkers as J. Miller, N. Chomsky, W. McCarthy and others. At the present stage of development, it is time to study the cognitive sciences as systems containing components operating in other systems and having different nature, and they connected with the original system in the complex functional dependence. The aim of investigation is the implementation of an integrated approach to the analysis of the phenomenon of cognitive sciences. The object of study - a cognitive science as a set. Subject of research – a specific complex relationship cognitive sciences and their implementation in a variety of applications. The work consists of four chapters. The first chapter is devoted to the history of the formation of the concept of cognitive science, the second chapter describes the basic methods of the cognitive sciences, the third chapter highlights the major features of complexing cognitive sciences, the fourth chapter builds complex cognitive science as an element of other polysystem. / Магистерская диссертация Плинер А.А. "Cognitive Science: комплексный подход" посвящена изучению когнитивных наук как комплекса научных исследований в различных областях философии, психологии, искусственного интеллекта, лингвистики, объединенных единым исследовательским интересом к вопросу познания. Возникновение интереса к когнитивным наукам можно отнести к середине XX в. и связать с работами таких мыслителей, как Дж. Миллер, Н. Хомский, У. Маккарти и других. На современном этапе развития пришло время изучения когнитивных наук как системы, содержащей элементы, функционирующие и в других системах, имеющих иную природу, и находящихся с первоначальной системой в сложной функциональной зависимости. Целью работы является осуществление комплексного подхода к анализу феномена когнитивных наук. Объект исследования – это когнитивные науки как комплекс. Предмет исследования – специфические комплексные взаимосвязи когнитивных наук и их реализация в различных сферах применения. Работа состоит из четырех глав. Первая глава посвящена истории формирования понятия когнитивных наук, вторая глава описывает основные методы когнитивных наук, третья глава выделяет основные комплексообразующие черты когнитивных наук, четвертая глава строит комплекс когнитивных наук как элемент других полисистем.

The information-seeking behaviour of science fiction and fantasy writers

Holappa, H. (Harri) 28 February 2017 (has links)
The topic of this master’s thesis is the information-seeking behaviour of creative writers in the genres of science fiction and fantasy. The artistic information-seeking behaviour on the whole has been the subject of only a handful of published studies, and creative writer studies have been almost non-existent. This study utilized the online questionnaire method with an emphasis on Likert items and nonparametric statistical analysis to answer the following research questions: 1) What are the information sources and channels used by SF&F writers in the three work roles of creative writing proposed by this study: the researcher, artisan and entrepreneur roles? 2) What characteristics of information sources are seen by SF&F writers to be the most important? 3) How writing genre, writing experience, writer attainment and gender affect their choice of information sources and channels? 4) What information barriers do they experience? The questionnaire was submitted to 16 English-speaking SF&F forums, drawing 130 participants from nine forums. The findings suggest that the information-seeking behaviour of SF&F writers is characterized by a heavy use of search engines, interpersonal sources and ‘the self’ as an information source. In the researcher role, additional importance is given to online encyclopedias and databases, to fiction and non-fiction, and to the nature and environment. Information-seeking in the artisan role is not associated with any particular sources, albeit buying behaviour might be higher. Information seeking in the entrepreneur role was shown to be more interpersonal in nature than in the other two roles. The most important source characteristic for SF&F writers is trustworthiness. Scifi writers are more frequent users of online news services than fantasy writers in the researcher role. Accumulating writing experience is associated with more frequent use of public libraries, archives and museums. Starting writers tend to use scholars and experts less. Those with 6–10 years of experience may have entered a period in their writing lives when career-related information seeking from online databases, media-sharing services and online news services is higher. Female writers tend to be more enthusiastic users of other people’s experiences in the researcher role, and of various channels of learning to write in the artisan and entrepreneur roles. AWriter attainment is slightly correlated with the writer having a little higher tolerance on poor accessibility and timeliness of sources, and him or her holding little less preference in already familiar sources. The majority of information barriers experienced by SF&F writers are environmental barriers, especially money-related ones. This study showed that there are patterns of behaviour among SF&F writers that, when researched further, enable a more holistic view on the general human information seeking. Understanding the different preferences in creative writers’ information seeking in the three work roles will also make the development of more effective and targeted information products and services possible, especially at those academic libraries serving student patrons in the growing number of higher education creative writing programs. / Tämän pro gradu -tutkielman aihe on tieteis- ja fantasiakirjoittajien tiedonhankintakäyttäytyminen. Aiempi taiteilijoita koskeva tiedonhankintakäyttäytymisen tutkimus on ollut vähäistä ja luovia kirjoittajia koskeva tutkimus lähes olematonta. Tutkielman metodi on verkkolomakkeella toteutettu kyselytutkimus, jonka painopisteet ovat Likert-asteikollisissa kysymyksissä ja epäparametrisessa tilastollisessa analyysissä. Tutkimuskysymykset ovat seuraavat: 1) Mitkä ovat tieteis- ja fantasiakirjoittajien käyttämät tiedonlähteet ja -kanavat kolmessa tämän tutkimuksen ehdottamassa työroolissa: tutkijarooli, artesaanirooli ja yrittäjärooli? 2) Mitkä tiedonlähteiden piirteet ovat kirjoittajien mielestä tärkeimmät? 3) Miten kirjoittajien genre, kokemus, rahalliseen ansioon yltäminen ja sukupuoli vaikuttavat tiedonlähteiden valintaan? 4) Mitä tiedonhankinnan esteitä kirjoittajat kohtaavat? Kyselylomake lähetettiin 16 englanninkieliselle tieteis- ja fantasiakirjoittamisen foorumille, ja se keräsi 130 vastaajaa yhdeksältä foorumilta. Tuloksista kävi ilmi, että tieteis- ja fantasiakirjoittajien tiedonhankintakäyttäytymistä luonnehtii hakukoneiden, interpersoonallisten lähteiden ja ”itsen” käyttö tiedonlähteenä. Tutkijaroolissa arvoa annetaan myös tietokannoille ja -sanakirjoille verkossa, fiktiiviselle ja tietokirjallisuudelle sekä luonnolle ja ympäristölle. Artesaaniroolin tiedonhankintaa ei hallitse mitkään tietyt lähteet, joskin lähteiden hankinta saattaa olla yleistä. Yrittäjäroolin tiedonhankinta on luonteeltaan interpersoonallisempaa kuin muiden. Tärkein tiedonlähteen piirre tieteis- ja fantasiakirjoittajille on luotettavuus. Tieteiskirjoittajat ovat fantasiakirjoittajia aktiivisempia verkkouutispalvelujen käyttäjiä tutkijaroolissa. Kirjoittamiskokemuksen kertyminen on liitoksissa yleisten kirjastojen, arkistojen ja museoiden käytön lisääntymiseen. Aloittelevat kirjoittajat käyttävät muita ryhmiä vähemmän hyväkseen asiantuntijoita ja tutkijoita. He joilla on 6–10 vuotta kirjoittajakokemusta saattavat olla urallaan vaiheessa, jossa kirjoittajauraan liittyvä tiedonhankinta on yleistä verkon tietokannoista, tietosanakirjoista, medianjakopalveluista ja uutispalveluista. Naispuoliset kirjoittajat hyödyntävät miehiä aktiivisemmin muiden ihmisten kokemuksia tutkijaroolissa ja joitakin kirjoittamaan oppimisen kanavia artesaani- ja yrittäjäroolissa. Rahalliseen ansioon yltäminen korreloi hiukan korkeamman tiedonlähteiden huonon tavoitettavuuden ja myöhäisyyden sietokyvyn kanssa sekä jo entuudestaan tuttujen lähteiden hiukan vähemmän suosimisen kanssa. Tieteis- ja fantasiakirjoittajien yleisimmät tiedonhankinnan esteet ovat ympäristöön ja erityisesti rahaan liittyvät esteet. Tutkielma osoitti, että tieteis- ja fantasiakirjoittajien tiedonhankintaan liittyy piirteitä, joita syvemmin tutkimalla voidaan päästä entistä kokonaisvaltaisempaan käsitykseen ihmisen tiedonhankinnasta. Ymmärtämällä luovien kirjoittajien tiedonhankintaa erilaisissa työrooleissa on myös mahdollista kehittää entistä parempia heille räätälöityjä informaatiopalveluja ja -tuotteita. Tämä pätee erityisesti niihin korkeakoulukirjastoihin, jotka palvelevat kansainvälisesti koko ajan kasvavaa joukkoa luovan kirjoittamisen opiskelulinjoissa olevia.

Learning to participate:participating to learn in science and mathematics classrooms

Kaartinen, S. (Sinikka) 15 August 2003 (has links)
Abstract The aim of this thesis is to examine the practices of classroom learning communities whose pedagogy in the learning of science and mathematics draws on the sociocultural perspective. This pedagogical framework views learning as a collective process of meaning making situated in cultural contexts. This research thesis illuminates the ways in which communal learning activity is constructed into being in the social interactions of classroom learning communities. Methodologically, this research is concerned with unravelling the dynamics of collaborative learning processes, and with examining how they give rise to the construction of diverse voices during participation in cultural activities. The empirical findings discussed in this thesis are derived from three case studies. Case Study 1 examines the nature of participation processes in science classrooms representing three age levels (Kaartinen & Kumpulainen, 2001). Case Study 2 focuses on the construction of explanations in a collaborative science learning project (Kaartinen & Kumpulainen, 2002). Case Study 3, reported in two articles, investigates the processes and conditions for collaborative reasoning in an elementary classroom context with a special interest in mathematics (Kumpulainen & Kaartinen, 2000, 2003). On the basis of the findings of this thesis, successful collaboration — joint effort towards a joint non-predetermined goal of action — can be said to require the growth of communicative consciousness. This means the ability to approach the problem under question from the point of view of another person and hence conversely, an ability to see one's own position from the point of view of other person. In this thesis, collaborative negotiation processes consisted of diverse interpretations, varying from informal to formal explanations, and from descriptive reasoning to causal reasoning. It seems evident that the traditional approach to teaching does not give students enough tools to elaborate their conceptions. However, the results of this thesis indicate that the collaborative learning situations here described have the power to provide students with opportunities to elaborate their explanations. The results of this thesis highlight the potential of the sociocultural approach to engage students in educational interaction, where diverse voices are able to participate and contribute to the ongoing discussion. The involvement of all students in collaborative discourses also poses challenges to sociocultural pedagogy, calling for educators to recognise and support varied opportunities for participation in educational discourse. The examples presented in this thesis are aimed at providing educators and researchers with lenses through which to examine the sociocultural practices of these classrooms and potentially further develop them. / Tiivistelmä Väitöstutkimukseni tarkoituksena on tutkia sosiokulturaalista pedagogiikkaa soveltavien oppijayhteisöjen käytänteitä matematiikan ja luonnontieteiden luokkahuoneissa. Tämän pedagogisen lähestymistavan mukaan oppiminen nähdään yhteisöllisenä, kulttuurisiin käytänteisiin liittyvänä osallistumis- ja merkityksenantoprosessina. Tutkimus valottaa yhteisöllisten opiskelutilanteiden rakentumista ja realisoitumista tutkimukseen osallistuneiden luokkahuoneiden sosiaalisessa vuorovaikutuksessa. Tässä tutkimuksessa kehitettyjen tutkimusmenetelmien avulla halutaan selvittää yhteistoiminnallisten opiskeluprosessien luonnetta ja sitä, kuinka näiden prosessien avulla voidaan tukea erilaisten lähestymistapojen osallistumista kulttuurisiin toimintoihin. Tutkimuksen empiiriset tulokset ovat peräisin kolmesta eri tapaustutkimuksesta. Ensimmäinen tapaustutkimus (Kaartinen & Kumpulainen, 2001) tarkastelee kolmea eri ikäkautta edustavien luonnontieteiden luokkahuoneiden osallistumisen prosessia. Toinen tapaustutkimus (Kaartinen & Kumpulainen, 2002) keskittyy selitysten rakentumisen tutkimiseen yhteistoiminnallisuutta soveltavassa luonnontieteiden opiskeluprojektissa. Kolmas tapaustutkimus, joka on raportoitu kahdessa eri artikkelissa (Kumpulainen & Kaartinen, 2000, 2003), tutkii yhteistoiminnallisen merkityksenantoprosessin rakentumista ja luonnetta ala-asteen geometrian opetuksessa. Tulosten perusteella kommunikatiivinen tietoisuus on onnistuneen yhteistoiminnallisuuden edellytyksenä matematiikan ja luonnontieteiden opiskelussa. Kommunikatiivinen tietoisuus tässä yhteydessä tarkoittaa kykyä lähestyä tarkasteltavaa ongelmaa toisen osallistujan näkökulmasta ja vastaavasi kääntäen, kykyä nähdä oma asemansa osallistuvan toisen näkökulmasta. Yhteistoiminnallisten selitysten luonteen tutkimus toi esille erilaisia lähestymistapoja akateemiseen tietoon matematiikan ja luonnontieteiden alalla. Tässä tutkimuksessa selitysten rakentuminen koostui erilaisista tulkinnoista ja vaihteli informaalista selittämisestä formaaliin selittämiseen sekä kuvailevasta selittämisestä syy- seuraussuhteita etsivään selittämiseen. Tulokset valottavat sosiokulturaalisen lähestymistavan mahdollisuutta sellaisen kasvatuksellisen vuorovaikutuksen rakentumisessa, joka tukee erilaisten tulkintojen osallistumisen ja vaikuttamisen mahdollisuutta merkityksenantoprosessiin. Haasteen muodostaa sellaisen kasvatuksellisen vuorovaikutuksen rakentaminen, jossa myös hiljaiset oppijat osallistuvat yhteisölliseen merkityksenantoprosessiin. Tutkimuksessa esitettävät empiiriset esimerkit tarjoavat kasvattajille ja tutkijoille välineitä, joiden avulla voidaan tarkastella ja mahdollisesti myös kehittää matematiikan ja luonnontieteiden luokkahuoneiden sosiaalisia käytänteitä.
