Skolan, radikalisering och det preventiva arbetet : En systematisk litteraturstudie om hur skolan kan fungera som ett verktyg i arbetet mot radikalisering / School, radicalization and preventive work : A  systematic litaratur review of how schools can be a tool in the preventive work against radicalization

Svensson, Sofia, Benslimen Bergström, Semi January 2019 (has links)
Ideologisk motiverad våldsbejakande extremism är ett resultat av en radikaliseringsprocess. Detta är ett stort problem och skolan har ett ansvar att arbeta preventivt mot detta problem. Syftet är att göra en systematisk litteraturstudie om hur skolan och lärare kan arbete på ett framgångsrikt sätt i syfte att minska riskerna för radikalisering. För att göra detta är det viktigt att ha koll på vilka faktorer som kan leda till radikalisering, vilka arbetsmetoder som har en preventiv effekt. Detta arbete är viktigt eftersom den svenska skolan har en central uppgift att fostra aktiva och demokratiska samhällsmedborgare. Detta är ett stort område och aktiva forskare har olika synsätt på radikaliseringsprocessen vilka presenteras i form av ett analysschema. Radikalisering sker till följd av att en individ utsätts för riskfaktorer sprungna ur psykiska och sociala problem. Det kan exempelvis handla om mental ohälsa, polarisering eller uppfostran. För att arbeta preventivt mot att elever radikaliseras har ett antal olika program som utformats. Exempel på sådana program är British prevent och Toleransprojektet. Dessa program innehåller framgångsfaktorer, detta innebär att vissa sätt att arbeta på eller vissa områden att arbeta kring har en preventiv effekt mot radikalisering. Framgångsfaktorerna kan bland annat innefatta värdegrundsarbete, relationskompetens hos lärare eller ökad tolerans bland eleverna.

Exploring Risk Factors on Chinese A Share Stock Market - in the Frame of Fama - French Factor Model / Exploration des facteurs de risque sur le marché boursier chinois A-share – dans le cadre du modèle facteur de Fama-French

Jiao, Wenting 21 September 2017 (has links)
Notre thèse explore les facteurs de risque et les modèles des facteurs sur le marché boursier chinois A-share. Notre étude est basée sur le contexte du modèle facteur de Fama-French (FF). Tout d'abord, au chapitre 1, nous réexaminons l'applicabilité du Modèle Fama-French à Trois Facteurs (FF3F) et du dernier Modèle Fama-French à Cinq Facteurs (FF5F), compte tenu de plusieurs caractéristiques spéciales du marché boursier chinois. Les résultats empiriques montrent que le Modèle FF3F peut expliquer la majorité des variations de séries chronologiques des rentabilités des actions chinoises A-share. Au cours de la période d'échantillonnage, le marché bêta et le facteur SMB sont des déterminants importants pour expliquer la variation transversale des rentabilités des actions, cependant nous ne trouvons aucune prime de valeur. D’après la comparaison des performances des modèles FF3F et FF5F en présence de facteurs de rentabilité et d'investissement, le Modèle FF5F ne semble pas capturer plus de variations de rentabilités espérées que le modèle à trois facteurs, à l'exception des six portefeuilles pondérées en valeurs qui formés à partir de la taille et de la rentabilité opérationnelle.Dans le chapitre 2, nous examinons si les facteurs FF, SMB et HML, sont des proxys d'innovations de variables d'état sélectionnées (rendement de dividende agrégée, taux de T-bonds en un mois, l’écart de terme et l’écart de défaut) qui décrivent, sur la période recherche, les opportunités futures d'investissement sur le marché boursier chinois A-share. Les régressions chronologiques et les régressions des séries transversales sont réalisées sur cinq modèles comparatifs en utilisant l'approche à deux étapes Fama-MacBeth. Les facteurs FF ne perdent pas leur pouvoir explicatif, avec ou sans la présence des innovations des quatre variables d’états sélectionnées, à la fois dans les examens de séries chronologiques et les examens transversaux. Nous trouvons que l'information contenue dans l'innovation de rendements de dividende agrégés semble totalement capturée par la combinaison du marché bêta et du facteur de taille. Les facteurs FF ont pu jouer un rôle limité de capturer d'opportunités d'investissement alternatives représentées par les innovations des quatre variables d'état sélectionnées.Dans le chapitre 3, nous étudions si les facteurs FF sont des proxys de facteurs de risque de détresse et si différentes méthodes de construction des facteurs entraînent des résultats différents. Les résultats empiriques suggèrent qu'il n'y a pas de preuve significative que les facteurs FF représentent un risque de détresse sur le marché boursier chinois A-share. En comparant les résultats des régressions des séries chronologiques à partir de deux méthodes différentes, la performance du facteur de risque de détresse basé sur le DLI semble légèrement meilleure que celui basé sur le O-score. Cependant, le facteur de risque de détresse n'est pas un déterminant important des rentabilités transversales moyennes, et les facteurs FF ne peuvent pas représenter le facteur de risque de détresse dans la section transversale du marché boursier chinois A-share. / This dissertation is to explore the risk factors and factor models on Chinese A-share stock market based on the context of Fama-French (FF) factor model. First of all, chapter 1 re-examines the applicability of Fama-French Three-Factor (FF3F) Model and the latest Fama-French Five-Factor (FF5F) Model considering several special features of Chinese stock market. FF3F Model can explain a majority of time-series variation of the Chinese A-share stock returns. The market beta and SMB are important determinants in explaining the cross-sectional variation in the average stock returns over the sample period; however, we find no value premium. Comparing the performance of both FF3F Model and FF5F Model on Chinese A-share stock market, in the presence of profitability and investment factors, FF5F Model seems not capture more variations of expected stock returns than the three-factor model except the six value-weighted portfolios formed on size and operating profitability.Chapter 2 examines whether FF factors SMB and HML proxy for the innovations of selected state variables (aggregate dividend yield, one-month T-bill rate, term spread and default spread) that describe future investment opportunities on Chinese A-share stock market during the research period. Both time-series and cross-sectional regressions are performed on five comparative models using Fama-MacBeth two-stage approach. FF factors don’t lose their explanatory power with or without the presence of the innovations of selected four state variables in both the time-series and cross-sectional examinations. We find that the information contained in innovation of aggregate dividend yields seems totally captured by the combination of market beta and size factor. FF factors might have played a limited role in capturing alternative investment opportunities proxied by innovations of the selected four state variables.Chapter 3 investigates whether FF factors proxy for distress risk factor and whether different methods of constructing factors result in the different outcomes. The empirical results suggest that there is no significant evidence that FF factors are proxying for distress risk on Chinese A-share stock market. Comparing the time-series regression results by using two different methods, the distress risk factor constructed based on DLI seems to perform slightly better than that constructed based on O-score in capturing time-series average returns. However, the distress risk factor is not an important determinant of cross-sectional average returns, and FF factors cannot proxy as distress risk factor in the cross-section on Chinese A-share stock market.

Syskons band i våldets spår : En tvärsnittsstudie av våldsutsatta barns självskattade kvalitet i syskonrelationer / Sibling Relationships in the Wake of Violence : A Cross-sectional Study of Self-Reported Sibling Relationship Quality in Children Subjected to Child Maltreatment

Jakobsson, Timea, Möllerström, Alexandra January 2022 (has links)
Syskonrelationen är den längsta relationen i livet. Därtill utgör syskonrelationen en viktig arena för barns utveckling. Trots detta finns det få studier där syskonrelationen undersöks i relation till barnmisshandel. I följande studie undersöktes skillnader i den självskattade stöd- och konfliktnivån i syskonrelationen, mellan barn som rapporterade svår barnmisshandel och barn i en kontrollgrupp, samt om kön förändrade dessa skillnader. Vidare undersöktes om stöd- och konfliktnivån påverkade den upplevda nivån av psykosomatiska problem hos barn som rapporterade svår barnmisshandel. Studien genomfördes på ett urval av 1 392 pojkar och flickor mellan 15-16 år, med data från projektet Longitudinal Research on Development in Adolescence (LoRDIA). Barn som rapporterade svår barnmisshandel upplevde signifikant lägre stödnivå och signifikant högre konfliktnivå i sin syskonrelation, än barnen i kontrollgruppen. Skillnaderna var signifikanta både för pojkar och flickor, men pojkar upplevde ett signifikant lägre stöd i sin syskonrelation än flickor. Nivån av syskonstöd och syskonkonflikt påverkade emellertid inte nivån av psykosomatiska problem hos barn som rapporterade svår barnmisshandel. Effektstorlekarna var små i majoriteten av resultaten, vilket tyder på att syskonrelationer är komplexa fenomen som vid sidan av barnmisshandel och kön, även påverkas av en rad andra faktorer. Resultaten diskuteras i ljuset av tidigare forskning och i relation till anknytningsteori, kompensationshypotesen, kongruenshypotesen och könssocialisation. / The relation between siblings is one of the longest throughout the life span. Moreover, the sibling relationship constitutes an important context for children’s development. Nevertheless, in the context of child maltreatment, it remains largely understudied. In this study, we examined the differences in self-reported sibling support and sibling conflict, between children who reported severe child maltreatment and children in a control group, as well as if these differences were affected by gender. Furthermore, we examined whether the level of sibling support and sibling conflict affected the extent of psychosomatic problems experienced by children who reported severe child maltreatment. The study was conducted on a sample of 1 392 boys and girls between the ages of 15-16, using data from the research project Longitudinal Research on Development in Adolescence (LoRDIA). Children who reported severe child maltreatment experienced significantly less sibling support and significantly higher sibling conflict than the control group. These differences were significant for both boys and girls, although boys experienced significantly less sibling support than girls. The level of sibling support and sibling conflict, however, did not affect the extent of psychosomatic problems in children who reported severe child maltreatment. Effect sizes were small in the majority of the results, suggesting that sibling relationships is a complex phenomenon that, besides child maltreatment and gender, may be affected by a number of other factors as well. The results are discussed in light of previous research, and in relation to attachment theory, the compensation hypothesis, the congruence hypothesis, and gender socialization.

Self-Measured Blood Pressure Monitoring in Hypertension Control: The Role of Social Determinants of Health, Current State in the United States, and Future Directions

Oke, Adekunle 01 May 2022 (has links)
Hypertension, a medical condition, predisposes to other cardiovascular diseases, and can be impacted by the social determinants of health (SDOH). Self-measured blood pressure monitoring (SMBP) is an evidence-based approach to hypertension control, but not much is known about the influence of SDOH on SMBP. This dissertation aims to: 1) highlight the SDOH factors whose relationship with SMBP have been explored in research studies; 2) examine the relationship between SDOH and SMBP among United States (U.S.) adults with high blood pressure; and 3) examine the current state of SMBP in the U.S., highlight policy implications from the empirical study and provide recommendations. Aims 1 and 2 were informed by an adapted SDOH framework, which comprised of upstream structural determinants, and downstream intermediary determinants. Aim 1 was achieved via a scoping review of studies across three databases following the PRISMA-SCR checklist. Aim 2 was achieved via a cross-sectional analysis of data from adult respondents to the 2019 Behavioral Risk Factor Surveillance System, with self-reported hypertension. Bivariate and Multiple Logistic regression analyses were conducted. Aim 3 involved a literature scan on policy concerning SMBP, highlighting the policy implications of findings from the empirical study, and providing recommendations for policy/practice. For aim 1, findings suggest that research studies examined the relationship of relatively more structural determinants, than the few, but highly significant intermediary determinants, with SMBP. For aim 2, looking at the structural determinants, males and those who identify as Black and other minority racial groups were more likely to report SMBP. For intermediary determinants, respondents who consumed fruits, vegetables, and exercised were likely to report SMBP, while those who smoke, who drink, and those with poor mental health days were less likely to report SMBP. Respondents with health coverage and whose provider recommended SMBP were likely to report SMBP use. Those ≥65 years were more likely to report SMBP. For aim 3, I recommend that the Centers for Medicare and Medicaid Services lead policy efforts on SMBP reimbursements. Also, healthcare practices should strengthen their technological infrastructure e.g., telehealth to promote access, and Electronic Health Records to promote efficient data collection and tracking.

A Model to Assess Supply Risk for Antibiotics in Swedish Context : Analysis of Supply Structure of 39 Selected Antibiotics

Sriram, Prasad, Milind, Abhishek January 2020 (has links)
The gap between demand and supply for antibiotics in the healthcare sector has seen a steady growth over the past decades, further increasing the risk of antibiotic resistance and unavailability in the Swedish healthcare sector and market. The thesis is part of the work of the multisectoral platform, PLATINEA, which is working towards better availability of antibiotics. This study focuses on analysing the supply structure of antibiotics and pharmaceutical supply chains using a risk assessment model. A literature review of previous research has been done to identify risk factors, understand their importance and develop the risk assessment model. The risk assessment model uses these risk factors to assess the supply risk of an antibiotic. The study is designed in a quantitative manner, where the antibiotics are classified as very high, high, medium, and low risk of shortage using risk scores. Expert opinions were collected using a self-completion questionnaire, in which experts allocate weights that measure the importance of said risk factors. Weights were used to measure value of risk for antibiotics using MCDA process. The outcomes of the study are (1). the weights of risk factors given by industry experts, (2). the developed multi-criteria risk assessment model, (3). ranking of selected 39 antibiotics from high to low supply risk, based on re-assessed risk scores.

Educational Intervention: Effects on Heart Disease Risk Factor Knowledge Among African Americans

Smith, Linda M 01 January 2015 (has links)
Abstract Fatal coronary heart disease among African Americans is associated with a disproportionate burden of cardiovascular disease (CVD) risk factors. Research has indicated that CVD risk factor knowledge and the prevalence of ideal CVH both persist at suboptimal levels. However, few researchers have investigated the relationship between culturally-tailored community-based heart health sessions, short-term knowledge acquisition of CVD risk factors, and the awareness of the American Heart Association's (AHA's) CVH construct. The purpose of this cross-sectional, secondary analysis study was to examine the interplay between these variables in an urban African American sample. Guided by social cognitive theory, the study analyzed de-identified data (data sets of demographic characteristics and Heart Disease Facts Questionnaire) from participant responses collected at multiple community sites to assist in the planning of future health programs. Multiple community sites were randomized into an intervention (n = 50) or comparison group (n = 57). Pearson's correlation and multiple regression were used to analyze data. Knowledge was higher for intervention group participants (β =.44, p = .001) and tended to be higher for those with more education (β = .20, p = .06) and those with less income (β = -.22, p = .07). Notably, most participants (73%) reported awareness of the AHA construct, CVH. The results support culturally-tailored interventions as a useful strategy for CVD risk reduction. The implication for social change is that initiatives at the community-level may positively impact CVH in minority/ethnic communities and subsequently impact CVD disparities.
