Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The thesis consists of four papers, summarized as follows. Do Host Country Educations Even Out the Playing Field? Immigrant-Native Labor Market Gaps in Sweden This study follows a cohort of students from Swedish compulsory school graduation in 1988 until 2002 to document differences in education, including grades and field of education, and labor market outcomes between immigrants and natives. Results indicate initial differences in youth labor market status and long term differences in employment rates, most notably for those with Non-European backgrounds. Acculturation Identity and Higher Education: Is There a Trade-off Between Ethnic Identity and Education? This paper examines the role of identification to home and host cultures on the pursuit of higher educations for individuals with immigrant backgrounds. Identity is defined according to a two-dimensional acculturation framework based on strength of identification to both ethnic background cultures and the majority culture. The results put into question the premise of oppositional identities. Is It How You Look or Speak That Matters? -An Experimental Study Exploring the Mechanisms of Ethnic Discrimination Using a laboratory experiment, we explore the following questions: Are beliefs about performance affected by if a candidate is perceived to have looks that are non-stereotypical for the dominant population? Do these beliefs change if the candidate has a native-like vs. accented speech? We find that candidates not perceived as stereotypically Swedish are considered to be worse performers. When candidates are presented by both looks and speech, we find negative beliefs for candidates that speak Swedish with a foreign-accent. Sector Differences in the Glass Ceiling in Sweden -Is Occupational Segregation the Explanation? This paper explores sector differences in how the gender wage gap varies across the wage distribution and examines the role of occupational segregation in explaining this variation for Sweden. Results indicate that the phenomenon known as the glass ceiling is stronger in the public sector than in the private sector. This difference is found to be due to occupational segregation.

- A search for a new resonance decaying to a W or Z boson and a Higgs boson in the [Formula: see text] final states is performed using 20.3 fb[Formula: see text] of pp collision data recorded at [Formula: see text] 8 TeV with the ATLAS detector at the Large Hadron Collider. The search is conducted by examining the WH / ZH invariant mass distribution for a localized excess. No significant deviation from the Standard Model background prediction is observed. The results are interpreted in terms of constraints on the Minimal Walking Technicolor model and on a simplified approach based on a phenomenological Lagrangian of Heavy Vector Triplets.

- Studies of the spin and parity quantum numbers of the Higgs boson in the [Formula: see text] final state are presented, based on proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb[Formula: see text] at a centre-of-mass energy of [Formula: see text] TeV. The Standard Model spin-parity [Formula: see text] hypothesis is compared with alternative hypotheses for both spin and CP. The case where the observed resonance is a mixture of the Standard-Model-like Higgs boson and CP-even ([Formula: see text]) or CP-odd ([Formula: see text]) Higgs boson in scenarios beyond the Standard Model is also studied. The data are found to be consistent with the Standard Model prediction and limits are placed on alternative spin and CP hypotheses, including CP mixing in different scenarios.

- A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2012 at [Formula: see text] TeV from pp collisions corresponding to an integrated luminosity of 20.3 fb[Formula: see text]are examined. Particles producing anomalously high ionisation, consistent with long-lived massive particles with electric charges from [Formula: see text] to [Formula: see text] are searched for. No signal candidate events are observed, and 95 % confidence level cross-section upper limits are interpreted as lower mass limits for a Drell-Yan production model. The mass limits range between 660 and 785 GeV.
