Essays on Labor Market Disparities and Discrimination : Immigration, Education and Gender

Doctoral thesis (other academic/artistic)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.

Do I belong to this society? The role of positive inter-ethnic climate in class and fairness of teachers

Conference paper (peer-reviewed)abstract
- Social alienation and marginalization among immigrant youth are important risk factors for their adjustment and integration into the host society. Thus, it is very essential to develop a comprehensive understanding on why some immigrant youth feel belong to the host society whereas others do not. One of the indicators of societal belongingness among immigrant youth could be related to the nature of their interpersonal experiences in school with their peers and teachers. Immigrant youth who experience positive inter-ethnic contact in class and treated fairly by their teachers may develop greater feelings of class belonging and social trust, and in turn, they may feel part of the host society. To test these conceptual arguments, we examined (1) whether positive inter-ethnic class climate and fair treatment of teachers are associated with societal belonging, and (2) whether adolescents’ feelings of class belonging and social trust explain these links.The data came from the first wave of an ongoing three-year longitudinal study, the Youth & Diversity Project. The analytical sample included youth with at least one parent born outside of Sweden (N = 423; Mage = 13.19, SD = .51; 44% girls). The results of mediation analysis showed that class belonging significantly mediated the association between positive inter-ethnic class climate and societal belonging, βind=.13, z = 3.85, p < .001, 95% CI: .08, .22. In addition, social trust significantly mediated the link between fair treatment of teachers and societal belonging, βind=.04, z = 1.96, p < .05, 95% CI: .01, .08. Overall, these findings suggest that experiencing positive inter-ethnic relationships in school may help immigrant youth develop connection to their immediate social context, and in turn build feelings of societal belonging. Furthermore, fair treatment of teachers may promote social trust among immigrant youth, and indirectly lead to feeling belong to the larger society.

Symmetrical doherty amplifier with high efficiency over large output power dynamic range

Conference paper (peer-reviewed)abstract
- For the conventional Doherty power amplifiers, asymmetrical cells are used to achieve high efficiency over large (> 6 dB) output power dynamic ranges, i.e. larger class-C cell. In this paper, it will be theoretically proven that high efficiency over large dynamic ranges also can be achieved using symmetrical devices, while still maintaining full voltage and current swing of both transistor cells. Using a smaller class-C cell compared to the asymmetrical Doherty has the advantages of higher gain and power added efficiency (PAE). The proposed symmetrical Doherty concept is experimentally verified by a 3.5 GHz 28 Watt circuit demonstrator fabricated using identical GaN HEMT devices. An average power added efficiency of 52% and adjacent power leakage ratio of -52 dB is obtained with 9 dB peak-to-average power-ratio 20 MHz LTE test signals.
