Üldistatud lineaarsete mudelite kasutamine sotsiaalteadustes: praktikum

Üldistatud lineaarsed mudelid (ÜLM) on lineaarse regressioonimudeli tänapäeval laialdaselt kasutatav üldistus, mis võtab ühtsesse lihtsasse kasutusskeemi kokku mudelid, mida traditsiooniliselt tuntakse paljude erinevate nimede all (nt regressioon-, dispersioon- ja kovariatsioonanalüüs, logistiline ja Poissoni regressioon). Selline üldistus võimaldab erinevatest mudelitest paremini aru saada ning neid paindlikumalt rakendada. ÜLM ideestik on laialdaselt kasutusel paljudes erinevates teadusvaldkondades (sh sotsiaalteadused, psühholoogia, liikumis- ja sporditeadused jne) ning selle tundmine on nende valdkondade uurimistulemustest aru saamiseks üha olulisem. Kursusel käsitletakse ÜLM kasutamist programmiga R. Järgnevas kursuse materjalide kogumikus on (a) sissejuhatav tekst R-i kasutamisest, (b) praktikumijuhendid, ja (c) kursuse lisamaterjalid. Kõigis tekstides tuleks courier kirjas olev osa ise R-is järele proovida – praktikumid on sel viisil ka iseseisvalt läbi tehtavad

The perceptions and experiences of tenants living in a social housing initiative in Port Elizabeth

Social housing aims to redress the housing crisis that South Africa is currently facing given the backlog that was left in the provision of free basic housing. Research conducted on the low to the middle-income group from which South African social housing tenants originate, suggests that this income bracket experiences social, physical and mental health challenges. They are three times more likely to suffer from depression than their counterparts in developed countries. Little to no literature has been published focusing on tenants who represent low to middle-income groups living in social housing in South Africa. Furthermore, the researcher did not come across literature highlighting the perceptions and experiences of tenants, who represent these low to middle-income groups, and who live in social housing in South Africa. In the context of South African social housing, there is a gap in the literature about the perceptions and experiences of tenants living in a social housing initiative.Guided by the Social Constructionism and Sense of Community theoretical frameworks, the goal of this qualitative research study waste gain a better understanding about the perceptions and experiences of tenants living in a social housing initiative in South Africa. An exploratory and descriptive research design was employed, focusing on the tenants of one social housing initiative. A non-probability purposive sampling procedure was followed. Convenience sampling was applied and followed up by volunteer sampling techniques. The sample size consisted of 9 social housing tenants. Individual, semi-structured interviews were conducted by an independent interviewer and used to collect data and analyse themes. Trustworthiness and ethical considerations were adhered to on all levels.This research contributes to a greater understanding of the perceptions and experiences of tenants living in a social housing initiative. The study revealed that most tenants experienced an increased sense of safety in the social housing initiative as compared to the surrounding community. The study further revealed that lower-income tenants have concerns about the long-term affordability of rentals in social housing. Among others, the study recommends that social workers advocate for inclusive social and economic policies to promote greater inclusion of vulnerable groups from low-income backgrounds

Assessing opportunities for physical activity in the built environment of children: interrelation between kernel density and neighborhood scale

BACKGROUND: Built environment studies provide broad evidence that urban characteristics influence physical activity (PA). However, findings are still difficult to compare, due to inconsistent measures assessing urban point characteristics and varying definitions of spatial scale. Both were found to influence the strength of the association between the built environment and PA. METHODS: We simultaneously evaluated the effect of kernel approaches and network-distances to investigate the association between urban characteristics and physical activity depending on spatial scale and intensity measure. We assessed urban measures of point characteristics such as intersections, public transit stations, and public open spaces in ego-centered network-dependent neighborhoods based on geographical data of one German study region of the IDEFICS study. We calculated point intensities using the simple intensity and kernel approaches based on fixed bandwidths, cross-validated bandwidths including isotropic and anisotropic kernel functions and considering adaptive bandwidths that adjust for residential density. We distinguished six network-distances from 500 m up to 2 km to calculate each intensity measure. A log-gamma regression model was used to investigate the effect of each urban measure on moderate-to-vigorous physical activity (MVPA) of 400 2- to 9.9-year old children who participated in the IDEFICS study. Models were stratified by sex and age groups, i.e. pre-school children (2 to <6 years) and school children (6–9.9 years), and were adjusted for age, body mass index (BMI), education and safety concerns of parents, season and valid weartime of accelerometers. RESULTS: Association between intensity measures and MVPA strongly differed by network-distance, with stronger effects found for larger network-distances. Simple intensity revealed smaller effect estimates and smaller goodness-of-fit compared to kernel approaches. Smallest variation in effect estimates over network-distances was found for kernel intensity measures based on isotropic and anisotropic cross-validated bandwidth selection. CONCLUSION: We found a strong variation in the association between the built environment and PA of children based on the choice of intensity measure and network-distance. Kernel intensity measures provided stable results over various scales and improved the assessment compared to the simple intensity measure. Considering different spatial scales and kernel intensity methods might reduce methodological limitations in assessing opportunities for PA in the built environment

Pathological gambling in Estonia: Relationships with personality, self-esteem, emotional states and cognitive ability

Abstract Due to changes in gambling accessibility during the last decade gambling has become more widespread in Estonia and the prevalence of pathological gambling has sharply increased. The present study attempts to identify psychological characteristics of Estonian pathological gamblers. It has been shown that a wide range of social, economic, and individual factors (e.g. personality traits and emotional states) predict the likelihood of becoming a pathological gambler. In the present study, pathological gamblers' (N = 33) personality traits, self-esteem, self-reported emotional states and cognitive ability were compared to the respective characteristics in a non-gambling control group (N = 42) matched for age, gender and educational level. It was found that compared to controls, pathological gamblers had higher scores on Neuroticism (especially on its immoderation facet) and lower scores on Conscientiousness (especially on its dutifulness and cautiousness facets) and on self-esteem scale. They reported more negative emotional states during the previous month (especially depression and anxiety). Finally, pathological gamblers had lower general cognitive ability. In a logistic regression model, the likelihood of being a pathological gambler was best predicted by high immoderation score and low cognitive ability
