Impact of the mode of data collection on the quality of survey questions in social sciences

Revilla, Melanie Audrey 26 September 2012 (has links)
This dissertation studies the impact of the mode of data collection on the quality of answers to survey questions, defined as the product of reliability and validity. Using data from the Netherlands about different topics (media, social and political trust, satisfaction, political orientation, left-right self-placement, attitudes toward immigration), it shows that the quality is similar in a computed assisted face-to-face survey using show cards (the European Social Survey, ESS) and a web survey based on a probability sample (the LISS panel). This is true both at the level of single items and composite scores. It suggests that standardised relationships across variables can be compared across these two modes. On the contrary, telephone interviews lead to some differences in quality. For complex concepts, measurement equivalence also holds, meaning that means and unstandardised relationships can be compared across the faceto- face and web surveys mentioned previously. / Esta tesis estudia el impacto que el método de recolección de datos en encuestas tiene sobre la calidad de las respuestas, definida como el producto de la fiabilidad y la validez. Utilizando datos de Holanda sobre temas diversos (utilización de los medios de comunicación, confianza social y política, satisfacción, orientaciones políticas, autoubicación en la escala izquierda-derecha, actitudes hacia la inmigración), se muestra que la calidad es similar en una encuesta cara-a-cara asistida con ordenador y utilizando tarjetas (la Encuesta Social Europea) y una encuesta online basada en una muestra probabilística (el panel LISS). Esto se cumple tanto para los indicadores simples, como para indicadores complejos. Los resultados sugieren que las relaciones estandardizadas entre variables son comparables entre los dos métodos de recolección. Al contrario, las entrevistas telefónicas producen diferencias de calidad. Para conceptos complejos, la equivalencia de las mediciones también está garantizada: las medias y las relaciones no estandarizadas son comparables en las entrevistas cara-a-cara y online.

Determinants of psycho-social well-being of informal caregivers of physically challenged children in South-Western Nigeria

Oyeleke, Isaac Ajiboye January 2014 (has links)
Informal caregiving denotes care that is provided by a family member or friend rather than by a professional who is reimbursed for services. Assuming a caregiving role can be stressful and burdensome. The effects of caregiving on the caregiver's health are moderated by individual differences in resources and vulnerabilities, such as socioeconomic status, prior health status, and level of social support. This work describes the determinant of psycho-social well-being of informal caregivers of physically challenged children in southwest of Nigeria. This study is guided theoretically by Ryff”s psychosocial well-being theory, The study adopted expo facto research design. Multistage samplings involving the use of random and purposive techniques were used to select 812 respondents who are informal caregivers. Social support questionnaire, Social support satisfaction level, Ryff’s psychological well-being scale were used. Findings indicated that social support predicted psycho-social well-being of informal caregivers of physically challenged children. Social support and satisfaction level combine together have impact on psycho-social well-being of informal caregivers of physically challenged children. More also, socio-economic factors such as occupation, educational level and income also predict psycho-social well-being of informal caregivers. Finally, marital status and gender also contribute to well-being of caregivers. It was therefore, recommended that social inclusion should be pursued with de-institutionalization of children with disability. Parents of children with disability should be encouraged to form support group and as well as encouraging fathers of children with disability to take an active part in ensuring their children with disability well-being. More also, there is need to empower informal caregivers through training and education. More importantly governments at the three levels ( Federal, State and local) should assist caregivers at ensuring their own and that of their children with disability well-being through improvement on various existing social welfare services in the country.

The relevance, importance and applicability of sustainable development in Economic and Management Sciences (EMS) education

America, Carina Georgina 03 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: One of the main features of the Economic and Management Sciences (EMS) learning area is that it prepares learners to participate in an economically complex society where social justice and a healthy environment are key concerns. Teachers are faced with an important learning outcome in the EMS curriculum, namely Sustainable Growth and Development, requiring them to equip learners with an understanding of sustainability and to encourage critical reflection on the related processes. This research aims to explore EMS teachers’ underlying conceptual understanding of sustainable development and to establish how these understandings relate to their teaching practices. The meaning of sustainable development has elicited multiple and contested reactions in the literature. Many authors are in agreement that development strategies should be consistent with the planet’s resources and linked to a balance between society, economy and the environment. However, increased production and consumption resulting from neoliberal economic policies and intensified global competition invariably disturb the earth’s ecosystem. On the one hand, increased economic activity has the advantage of resource development (capital, natural and human resources) that promotes economic growth. On the other hand, this growth occurs at the expense of resource exploitation which in turn leads to environmental degradation, the erosion of cultural identities, health risks and, in many instances, unsustainable lifestyles. There is a growing consensus that knowledge and a changed mindset are required for developing an enhanced focus towards a sustainable future. Education for Sustainable Development (ESD) provides the knowledge, skills, values and theories for promoting sustainable development. The research was conducted within a constructivist-interpretivist paradigm. A case study design strategy, as part of a qualitative research approach, was selected to best answer the research question. The data collection was done by means of the literature reviewed, in-depth interviews and subject-object interviews (written explanations). This was followed by the systematic categorisation and coding of the data by means of content analysis. The main finding of the study was that EMS teachers had a single focus with regard to sustainable development: their understanding predominantly related to the economic pillar of sustainable development. The interrelatedness of the economy, society and the environment to achieve sustainable development objectives was not subjected to much scrutiny. This research showed that there is a need for ESD to be integrated into the EMS discourse. / AFRIKAANSE OPSOMMING: Een van die uitstaande kenmerke van die leerarea: Ekonomiese en Bestuurswetenskappe (EBW) is dat dit leerders voorberei vir deelname binne 'n ekonomies komplekse samelewing waar maatskaplike geregtigheid en ‘n gesonde omgewing ‘n kern-uitdaging vorm. Onderwysers word gekonfronteer met 'n belangrike leeruitkoms in die EBW-kurrikulum, naamlik Volhoubare Groei en Ontwikkeling, wat van hulle verwag om leerders toe te rus met 'n begrip van volhoubaarheid en om kritiese refleksie oor verwante prosesse te stimuleer. Hierdie navorsing het ten doel om die onderliggende konseptuele begrip van volhoubare ontwikkeling by EBW-onderwysers te verken en vas te stel hoe hierdie begrip betrekking het op hul onderrig praktyke. Die betekenis van volhoubare ontwikkeling het verskeie en omstrede reaksies in die literatuur ontlok. Baie outeurs stem saam dat die ontwikkeling van strategieë in ooreenstemming moet wees met die planeet se hulpbronne en gekoppel moet word aan 'n balans tussen die samelewing, die ekonomie en die omgewing. Verhoogde produksie en verbruik, as gevolg van die neoliberale ekonomiese beleid, versterk egter wêreldwye mededinging en versteur sodoende die aarde se ekosisteem. Enersyds het toenemende ekonomiese aktiwiteit die voordeel van hulpbronontwikkeling (kapitaal, natuurlike en menslike hulpbronne) wat ekonomiese groei bevorder. Andersyds vind hierdie groei plaas ten koste van hulpbronbenutting, wat weer lei tot die agteruitgang van die omgewing, die aftakeling van kulturele identiteit, gesondheidsrisiko's, en, in baie gevalle, nie-volhoubare lewenstyle. Daar is 'n groeiende konsensus dat kennis en 'n verandering in denkwyse nodig is om ‘n sterker fokus op 'n volhoubare toekoms te verseker. Opvoeding vir Volhoubare Ontwikkeling (OVO) verskaf die kennis, waardes en teorieë vir die vestiging van volhoubare ontwikkeling. Hierdie navorsing is onderneem binne 'n konstruktivisties-interpretivistiese paradigma. Om die beste antwoord op die navorsingsvraag te bied, is ‘n kwalitatiewe navorsingsbenadering gekies en ‘n gevallestudie-ontwerpstrategie gevolg. As deel van die data-insameling is die literatuur voortdurend verken en in-diepte onderhoude is gevoer, gevolg deur geskrewe verduidelikings. Hierna is die sistematiese kategorisering en kodering van die data deur middel van 'n inhoudsanalise gedoen. Die belangrikste bevinding van die studie was dat die EBW-onderwysers 'n enkele fokus gehad het ten opsigte van volhoubare ontwikkeling: hul begrip het hoofsaaklik betrekking gehad op die ekonomiese pilaar van volhoubare ontwikkeling. Daar was deurgaans 'n gebrek aan kritiese refleksie oor die interverwantskap tussen die ekonomie, die samelewing, die omgewing en die wyse waarop die doelwitte van volhoubare ontwikkeling bereik kan word. Hierdie navorsing het getoon dat daar 'n behoefte bestaan om OVO binne die EBWleerarea te integreer.

Pupils' interest in Science

Afandi, Misa Abdallah January 2015 (has links)
Abstrakt Syftet med detta arbete är att undersöka vad lärare kan göra för att motivera eleverna till NO- lektionen. Undersökningen syftar till att se om det finns skillnader mellan pojkars och flickors intresse för naturvetenskap. Detta examensarbete bygger på en intervjuundersökning som genomfördes i sjundeklass med åtta elever, fyra pojkar och fyra flickor. Undersökningen visade att läraren har stor betydelse för att väcka intresse hos eleverna. Detta sker genom att variera undervisningen efter elevernas behov. Undervisningen visade också att intresset för naturvetenskap skiljer sig åt mellan pojkar och flickor. Pojkarna är mest motiverade till kemiområdet, medan flickorna är mest motiverade till biologiområdet. Dessutom är flickorna mer intresserade av att välja NO-linje i gymnasiet.

Social media mining as an opportunistic citizen science model in ecological monitoring: a case study using invasive alien species in forest ecosystems.

Daume, Stefan 27 August 2015 (has links)
Dramatische ökologische, ökonomische und soziale Veränderungen bedrohen die Stabilität von Ökosystemen weltweit und stellen zusammen mit neuen Ansprüchen an die vielfältigen Ökosystemdienstleistungen von Wäldern neue Herausforderungen für das forstliche Management und Monitoring dar. Neue Risiken und Gefahren, wie zum Beispiel eingebürgerte invasive Arten (Neobiota), werfen grundsätzliche Fragen hinsichtlich etablierter forstlicher Managementstrategien auf, da diese Strategien auf der Annahme stabiler Ökosysteme basieren. Anpassungsfähige Management- und Monitoringstrategien sind deshalb notwendig, um diese neuen Bedrohungen und Veränderungen frühzeitig zu erkennen. Dies erfordert jedoch ein großflächiges und umfassendes Monitoring, was unter Maßgabe begrenzter Ressourcen nur bedingt möglich ist. Angesichts dieser Herausforderungen haben Forstpraktiker und Wissenschaftler begonnen auch auf die Unterstützung von Freiwilligen in Form sogenannter „Citizen Science“-Projekte (Bürgerwissenschaft) zurückzugreifen, um zusätzliche Informationen zu sammeln und flexibel auf spezifische Fragestellungen reagieren zu können. Mit der allgemeinen Verfügbarkeit des Internets und mobiler Geräte ist in Form sogenannter sozialer Medien zudem eine neue digitale Informationsquelle entstanden. Mittels dieser Technologien übernehmen Nutzer prinzipiell die Funktion von Umweltsensoren und erzeugen indirekt ein ungeheures Volumen allgemein zugänglicher Umgebungs- und Umweltinformationen. Die automatische Analyse von sozialen Medien wie Facebook, Twitter, Wikis oder Blogs, leistet inzwischen wichtige Beiträge zu Bereichen wie dem Monitoring von Infektionskrankheiten, Katastrophenschutz oder der Erkennung von Erdbeben. Anwendungen mit einem ökologischen Bezug existieren jedoch nur vereinzelt, und eine methodische Bearbeitung dieses Anwendungsbereichs fand bisher nicht statt. Unter Anwendung des Mikroblogging-Dienstes Twitter und des Beispiels eingebürgerter invasiver Arten in Waldökosystemen, verfolgt die vorliegende Arbeit eine solche methodische Bearbeitung und Bewertung sozialer Medien im Monitoring von Wäldern. Die automatische Analyse sozialer Medien wird dabei als opportunistisches „Citizen Science“-Modell betrachtet und die verfügbaren Daten, Aktivitäten und Teilnehmer einer vergleichenden Analyse mit existierenden bewusst geplanten „Citizen Science“-Projekten im Umweltmonitoring unterzogen. Die vorliegenden Ergebnisse zeigen, dass Twitter eine wertvolle Informationsquelle über invasive Arten darstellt und dass soziale Medien im Allgemeinen traditionelle Umweltinformationen ergänzen könnten. Twitter ist eine reichhaltige Quelle von primären Biodiversitätsbeobachtungen, einschließlich solcher zu eingebürgerten invasiven Arten. Zusätzlich kann gezeigt werden, dass die analysierten Twitterinhalte für die untersuchten Arten markante Themen- und Informationsprofile aufweisen, die wichtige Beiträge im Management invasiver Arten leisten können. Allgemein zeigt die Studie, dass einerseits das Potential von „Citizen Science“ im forstlichen Monitoring derzeit nicht ausgeschöpft wird, aber andererseits mit denjenigen Nutzern, die Biodiversitätsbeobachtungen auf Twitter teilen, eine große Zahl von Individuen mit einem Interesse an Umweltbeobachtungen zur Verfügung steht, die auf der Basis ihres dokumentierten Interesses unter Umständen für bewusst geplante „Citizen Science“-Projekte mobilisiert werden könnten. Zusammenfassend dokumentiert diese Studie, dass soziale Medien eine wertvolle Quelle für Umweltinformationen allgemein sind und eine verstärkte Untersuchung verdienen, letztlich mit dem Ziel, operative Systeme zur Unterstützung von Risikobewertungen in Echtzeit zu entwickeln.

Religion, intolerance, and social identity

Walters, Handri 03 1900 (has links)
Thesis (MA (Political Science))--Stellenbosch University, 2009. / ENGLISH ABSTRACT: Over the past few decades the secular world has witnessed an increasing assault, specifically from the monotheistic religious fundamentalist community, on their beliefs and values. The undeniable intolerance shown by the religious fundamentalist community has often translated into violent terrorist attacks against the secular world. The fact that religious beings can resort to such atrocious acts of violence has certainly baffled many onlookers. It surely comes as no surprise that religious fundamentalism is generally viewed as a ''hard-to-understand‟ phenomenon. This literature review will describe the ''hard-to-understand‟ phenomenon that is religious fundamentalism by employing social identity theory. The social identity of religious fundamentalists is generally derived from sacred texts and what they consider to be absolute truths. These presumed absolute truths not only provide ample opportunity for the development of the ''us‟/''them‟ duality, but also provide a platform for an intense intolerance of the ''other‟, also referred to as the out-group. Of course, the ''us‟/''them‟ duality can be created on many social dimensions, but religion has proven to bring quite an extensive, even murderous, intolerance to in- and out-group characterizations. The ever increasing actions of religious fundamentalist groups over the past few decades have certainly illustrated this point with some conviction. The importance of social identity has been recognised in many major traditions of the social sciences, not excluding political science. Social identity forms the basis of any group‟s actions or reactions. Therefore, its significance stretches far beyond simply providing an identity to a social group. Social identity also acts as a preamble to how a social group, in this case religious fundamentalists, chooses to deal with invidious comparisons. By employing social identity in this particular way we can go beyond investigating how religious fundamentalists act and react to the point of understanding why they act and react the way they do. In this study it was found that although a number of options to deal with invidious comparisons are available to social groups, only a few of these options are likely to be pursued by religious fundamentalists in order to remain a relevant and competitive social group within the social hierarchy. This approach will provide important insights into a formerly ''hard-to-understand‟ phenomenon namely religious fundamentalism. / AFRIKAANSE OPSOMMING: Oor die laaste paar dekades het die sekulêre wêreld 'n toenemende aanslag op sy oortuigings en waardes waargeneem, spesifiek vanaf die monoteïstiese godsdienstige fundamentalistiese gemeenskap. Die onloënbare onverdraagsaamheid wat deur hierdie godsdienstige fundamentalistiese gemeenskap getoon word ontaard dikwels in geweldadige terroriste aanvalle op die sekulêre wêreld. Die feit dat godsdienstige individue hulself begwewe tot sulke wreedaaardige dade van geweld het verseker baie toeskouers verydel. Dis is sekerlik dan nie 'n verrassing dat godsdienstige fundamentalisme gesien word as 'n ''moelik-om-te-begryp‟ fenomeen nie. Hierdie literatuur oorsig sal die ''moelik-om-te-begryp‟ fenomeen wat godsdienstige fundamentalisme is beskryf deur gebruik te maak van die sosiale identiteits teorie. Die sosiale identiteit van godsdienstige fundamentaliste spruit oor die algemeen uit heilige teks en absolute waarhede. Hierdie absolute waarhede bied nie slegs ruim geleenthede vir die ontwikkeling van die ''ons‟/''hulle‟ dualiteit nie, maar bied ook 'n platform vir 'n intense onverdraagsaamheid van die 'ander‟, wat ook verwys word na as die buite-groep. Natuurlik kan die ''ons‟/''hulle‟ dualiteit op grond van baie ander sosiale dimensies ontwikkel word, maar godsdiens het telke male al gedemonstreer dat dit 'n omvattende, selfs moordadige, onverdraagsaamheid na binne- en buite-groep karakterisering bring. Die al ewige toenemende aksies van godsdienstige fundamentalistiese groepe oor die laaste paar dekades illustreer sekerlik hierdie punt met oortuiging. Die belangrikheid van sosiale identiteit word erken deur verskeie tradisies van die sosiale wetenskappe en politieke wetenskap word nie hier uitgesluit nie. Sosiale identiteit vorm die basis van enige groep se aksies en reaksies. Vir hierdie rede strek die betekenisvoheid ver verby die feit dat slegs 'n identiteit aan 'n sosiale groep verskaf word. Sosiale identiteit tree op as 'n voorrede vir die manier waarop 'n sosiale groep, in ons geval godsdienstige fundamentaliste, verkies om onbenydenswaardige vergelykings te hanteer. Deur sosiale identiteit op hierdie besondere manier aan te spreek kan ons verder gaan as om slegs ondersoek in te stel in hoe godsdienstige fundamentaliste optree en reageer tot die punt waar ons kan verstaan hoekom hulle optree en reageer op hierdie spesifieke manier. In hierdie studie is gevind dat alhoewel daar 'n aantal opsies beskikbaar is vir sosiale groepe om onbenydenswaardige vergelykings te hanteer, is daar slegs 'n paar van hierdie opsies wat mees waarskynlik nagestreef sal word deur godsdienstige fundamentaliste ten 'n einde 'n relevante en kompeterende sosiale groep binne die sosial hïerargie te wees. Hierdie benadering sal belangrike insigte bring tot die voormalige 'moeilik-om-te-begryp‟ fenomeen genaamd godsdienstige fundamentalisme.
