Adolescent Cognitive and Non-cognitive Correlates of Adult Health
No full textWhile it is widely acknowledged that the family and childhood environments affect adult well being, why they matter is still an area of significant debate. Previous research concerned with this issue has focused on the influence of family income, family structure, and cognitive ability. Much of this research has focused on economic and social outcomes. Notably, the influence of childhood environments on adult health has not received as much attention as other outcomes, and when health has been the focus, interest has been mainly on childhood health. Here, I present a descriptive analysis of the associations between cognitive and non-cognitive traits measured at the end of childhood (age 14) and mental and physical health at age 41. Results suggest that, on average, adolescent cognitive ability and self esteem have a significant association with health at age 41. Other non-cognitive factors such as locus of control and adolescent substance use do not have significant associations with adult health. Net of adolescent influences, completed education has a significant association with adult health.
Searches for direct supersymmetric gaugino and slepton pair production in final states with leptons with the ATLAS detector
No full textA search for direct production of supersymmetric gauginos and sleptons in final states with two and three leptons is presented. The two lepton analysis uses 4.7 fb−1 of proton-proton collision data at √s = 7 TeV, while the three lepton analysis uses 13 fb−1 at √s = 8 TeV. All data were recorded by the ATLAS detector at the Large Hadron Collider. The results are interpreted in the phenomenological minimal supersymmetric Standard Model, as well as simplified models. No significant excess above the Standard Model expectation is observed. Limits on the particle masses are placed at the 95% confidence level. In simplified models, chargino masses are excluded up to 580 GeV

No full textLuminosity determination and searches for supersymmetric sleptons and gauginos at the ATLAS experiment
No full textThis thesis documents my work in the luminosity and supersymmetry groups of the ATLAS experiment at the Large Hadron Collider. The theory of supersymmetry and the concept of luminosity are introduced. The ATLAS experiment is described with special focus on a luminosity monitor called LUCID. A data-driven luminosity calibration method is presented and evaluated using the LUCID detector. This method allows the luminosity measurement to be calibrated for arbitrary inputs. A study of particle counting using LUCID is then presented. The charge deposited by particles passing through the detector is shown to be directly proportional to the luminosity. Finally, a search for sleptons and gauginos in final states with exactly two oppositely charged leptons is presented. The search is based on 20.3 fb of collision data recorded with the ATLAS detector in 2012 at a center-of-mass energy of TeV. No significant excess over the Standard Model expectation is observed. Instead, limits are set on the slepton and gaugino masses

No full textA search for direct production of supersymmetric gauginos and sleptons in final states with two and three leptons is presented. The two lepton analysis uses 4.7 fb(-1) of proton-proton collision data at root s = 7 TeV, while the three lepton analysis uses 13 fb(-1) at root s = 8 TeV. All data were recorded by the ATLAS detector at the Large Hadron Collider. The results are interpreted in the phenomenological minimal supersymmetric Standard Model, as well as simplified models. No significant excess above the Standard Model expectation is observed. Limits on the particle masses are placed at the 95% confidence level.

No full textFollowing in Your Father's Footsteps: A Note on the Intergenerational Transmission of Income between Twin Fathers and their Sons
No full textWe provide the first twin-based estimates of the intergenerational transmission of income between fathers and sons. Using Swedish register data on the income of monozygotic twin fathers and their sons, we are able to control for unobserved endowments at the twin-pair level when estimating the intergenerational relationship. We find a cross-sectional intergenerational income elasticity of 0.276, while our twin-based intergenerational income elasticity is 0.12. This is close to the estimate of 0.10 found by Björklund et al. (2006) using an adoption design. This suggests that at most half of the income transmission can be given a causal interpretation.twins, income, intergenerational transmission, intergenerational mobility
Self-reported health in mothers : The impact of age, and socioeconomic conditions
No full textThe aim of the present analysis was to study health and well-being in mothers compared to women without children, and to analyze potential interactions with age and socioeconomic conditions. The study comprised 5,368 Swedish women born in 1960-1979 who were interviewed in any of the population-based Surveys of Living Conditions during the period 1996-2003. Having children at home was related to self-reported health symptoms and. long-standing illness in multiple logistic regression models. The impact of age, cohabitation status, full-time or part-time work, and income level were analyzed. While mothers were less burdened by long-standing illness, partly due to selection mechanisms (a "healthy mother effect"), they experienced worse self-rated health and more fatigue than women without children, and the odds of poor self-rated. health and fatigue increased by number of children. Conditions that strengthened the association between motherhood and impaired health were young maternal age, full-time employment, high income, and being alone. The study indicates a need for improved negotiations between parents regarding a fair share of work and family duties and extended support for lone mothers to prevent adverse health effects in women combining children and work. ne results may be useful to policy-makers and employers in developing new policies.</p
Interaction Effects of Social Isolation and Peripheral Work Position on Risk of Disability Pension: A Prospective Study of Swedish Women and Men.
No full textPurposeThe study examines various combinations of levels of social isolation in private life and peripheral work position as predictors of disability pension (DP). A second aim was to test the potential interaction effects (above additivity) of social isolation and peripheral work position on the future risk of DP, and to provide results for men and women by age.MethodThe study was based on a sample of 45567 women and men from the Swedish population who had been interviewed between 1992 and 2007. Further information on DP and diagnoses was obtained from the Swedish Social Insurance Agency's database (1993-2011). The studied predictors were related to DP using Cox's proportional hazard regression. The analyses were stratified on sex and age (20-39 years, 40-64 years), with control for selected confounders.ResultsIncreased risks of DP were found for most combinations of social isolation and peripheral work position in all strata. The hazard ratios (HRs) for joint exposure to high degree of social isolation and a peripheral work position were particularly strong among men aged 20-39 (HR 5.70; CI 95% 3.74-8.69) and women aged 20-39 (HR 4.07; CI 2.99-5.56). An interaction effect from combined exposure was found for women in both age groups as well as a tendency in the same direction among young men. However, after confounder control the effects did not reach significance.ConclusionsIndividuals who were socially isolated and in a peripheral work position had an increased risk of future DP. The fact that an interaction effect was found among women indicates that a combination of social isolation and peripheral work position may reinforce adverse health effects. There was no evidence that a peripheral work position can be compensated by a high degree of social intergration in private life
