A Twin Protection Effect? Explaining Twin Survival Advantages with a Two-Process Mortality Model
2016
Twin studies that focus on the correlation in age-at-death between twin pairs have yielded important insights into the heritability and role of genetic factors in determining lifespan, but less attention is paid to the biological and social role of zygosity itself in determining survival across the entire life course. Using data from the Danish Twin Registry and the Human Mortality Database, we show that monozygotic twins have greater cumulative survival proportions at nearly every age compared to dizygotic twins and the Danish general population. We examine this survival advantage by fitting these data with a two-process mortality model that partitions survivorship patterns into extrinsic …
Gütekriterien qualitativer Sozialforschung. Ein Diskussionsanstoß
2018
Zusammenfassung Der Beitrag expliziert Gütekriterien der qualitativen Sozialforschung. Er geht von der Prämisse aus, dass Qualitätsmerkmale in diesem Segment empirischer Sozialforschung nur unter konsequentem Rekurs auf die spezifischen Funktionsbedingungen interpretativer und rekonstruktiver Verfahren zu bestimmen sind. Fünf Kriterien werden vorgeschlagen: Gegenstandsangemessen ist eine Weise der Herstellung des Forschungsgegenstandes, die das empirische Feld ernst nimmt und Methoden, Fragestellungen und Datentypen einer fortlaufenden Justierungsanforderung unterwirft. Empirische Sättigung reflektiert die Güte der Verankerung von Interpretationen im Datenmaterial. Theoretische Durchdringun…
El proyecto de investigación social como instrumento integrador de la praxis para los futuros/as trabajadores/as sociales
2015
El presente trabajo muestra los resultados de una investigación-intervención aplicada a los alumnos de cuarto curso de Grado en Trabajo Social. En este documento se articula una metodología de enseñanza colaborativa, significativa y crítica a partir de las evidencias de la práctica del Trabajo Social. Como conclusiones de este estudio se justifica el uso de la metodología Blended Learning en el espacio universitario. Se evidencia como con la participación y cooperación colectiva se favorece el desarrollo de competencias investigadoras, y se señala el proyecto de investigación social como herramienta que permite vincular las prácticas externas del alumnado con los elementos teóricos de la di…
Sequential Intensification of Metformin Treatment in Type 2 Diabetes With Liraglutide Followed by Randomized Addition of Basal Insulin Prompted by A1…
2012
OBJECTIVE We evaluated the addition of liraglutide to metformin in type 2 diabetes followed by intensification with basal insulin (detemir) if glycated hemoglobin (A1C) ≥7%. RESEARCH DESIGN AND METHODS In 988 participants from North America and Europe uncontrolled on metformin ± sulfonylurea, sulfonylurea was discontinued and liraglutide 1.8 mg/day added for 12 weeks (run-in). Subsequently, those with A1C ≥7% were randomized 1:1 to 26 weeks’ open-label addition of insulin detemir to metformin + liraglutide (n = 162) or continuation without insulin detemir (n = 161). Patients achieving A1C <7% continued unchanged treatment (observational arm). The primary end point was A1C change bet…
Effects of a Mediterranean Eating Plan on the Need for Glucose-Lowering Medications in Participants With Type 2 Diabetes: A Subgroup Analysis of the …
2019
OBJECTIVE: To examine the effects of two Mediterranean eating plans (Med-EatPlans) versus a low-fat eating plan on the need for glucose-lowering medications. RESEARCH DESIGN AND METHODS: From the Prevención con Dieta Mediterránea (PREDIMED) trial, we selected 3,230 participants with type 2 diabetes at baseline. These participants were randomly assigned to one of three eating plans: Med-EatPlan supplemented with extra-virgin olive oil (EVOO), Med-EatPlan supplemented with mixed nuts, or a low-fat eating plan (control). In a subgroup (15%), the allocation was done in small clusters instead of using individual randomization, and the clustering effect was taken into account in the statistical a…
Discrimination in the sharing economy: evidence from a Hungarian field experiment
2018
Findings from our pilot research project which focused on providing car sharing services to young people with different ethnic/racial background showed discrimination against certain ethnic groups. The research was based on a controlled field experimental design to examine the chances of rides being offered to racially different testers. The experimental variables were both race and gender. Creating altogether 8 profiles enabled us to test the interaction between these two experimental stimulus. The small-scale research (total N=160) was implemented in Hungary, in summer 2017 by interns of TARKI, Hungarian Social Research Centre. The forthcoming article shows evidence of ethnic/racial dispr…
Neighborhood characteristics and violence behind closed doors: The spatial overlap of child maltreatment and intimate partner violence
2018
In this study, we analyze first whether there is a common spatial distribution of child maltreatment (CM) and intimate partner violence (IPV), and second, whether the risks of CM and IPV are influenced by the same neighborhood characteristics, and if these risks spatially overlap. To this end we used geocoded data of CM referrals (N = 588) and IPV incidents (N = 1450) in the city of Valencia (Spain). As neighborhood proxies, we used 552 census block groups. Neighborhood characteristics analyzed at the aggregated level (census block groups) were: Neighborhood concentrated disadvantage (neighborhood economic status, neighborhood education level, and policing activity), immigrant concentration…
Students of Religion Studying Social Conflict Through Simulation and Modelling: An Exploration
2020
Researchers at our university use modelling and simulation (M&S) to study religious conflicts, and we wanted to introduce undergraduate students of religion to this research approach. Hence, we started a three-year educational design research project to empirically study ways to introduce these students to M&S as a viable research method in their discipline. The research project will entail several iterations, which aim to have a feasible and effective design of lessons and a better understanding of the learning processes. The first iteration was exploratory and is reported here. For this exploration, we organised a seminar, which was videotaped for post hoc analysis. The seminar started wi…
Constitució d'una comunitat social d'investigació amb persones majors des de la responsabilitat social universitària = Constitution of a Social Resea…
2012
Es presenta com s'ha constituït una comunitat social d'investigació (CSI) amb 48 persones majors institucionalitzades des de la responsabilitat social universitària (RSU) i des d'una perspectiva humanista. En aquesta CSI es va valorar el benestar psicològic de les persones institucionalitzades amb mètodes quantitatius i qualitatius, i amb una proposta d'investigació-acció participativa (IAP). S'inicia, així, un procés d'innovació epistemològica, amb escassos antecedents, a l'hora d'investigar i entendre el benestar de les persones majors. Aquesta primera experiència de la CSI aporta observacions sobre els canvis de les dimensions del benestar de Ryff durant el procés d'envelliment dins de l…
Perceiving need for lifestyle counseling: findings from Finnish individuals at high risk of type 2 diabetes.
2011
OBJECTIVE To investigate the proportion of individuals at high risk of type 2 diabetes who perceive the need for lifestyle counseling, factors associated with this perception, and whether the perceived need is associated with subsequent attendance in lifestyle intervention. RESEARCH DESIGN AND METHODS Baseline and intervention data were obtained from 10,149 participants in a Finnish National Diabetes Prevention Project. RESULTS In total, 36% of men and 52% of women perceived the need for counseling. Most of the risk factors did not increase the perceived need for counseling. Those agreeing to attend supervised lifestyle intervention were more likely to report a perceived need than those who…
