    Sammanfattning : The paper deals with various positivity and continuity questions arising in the Weyl calculus of pseudo-differential operators. Let W be a symplectic vector space. LÄS MER

  2. 2. Topics in Nonlinear Elliptic Differential Equations

    Författare :Shoyeb Waliullah; Andrzej Szulkin; Thomas Bartsch; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Concentration-compactness principle; critical Sobolev exponent; symmetric solutions of elliptic equations; degenerate elliptic equation; Nehari manifold; Caffarelli-Kohn-Nirenberg inequality; infinitely many solutions; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : In this thesis we examine the existence of solutions to nonlinear elliptic partial differential equations via variational methods.In Paper I we consider the existence of constrained minimizers which correspond to solutions of equations involving the iterated Laplacian, the iterated p-Laplacian and the critical Sobolev exponent.

  3. 3. Essays on Inequality and Education

    Författare :Erika Ekström; Per-Anders Edin; Peter Fredriksson; Arne Bigsten; Paul Gregg; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Income distribution; Discrimination; Namibia; Vocational education; University enrolment; Unemployment; Adult education; Wage earnings; Nationalekonomi; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of an introduction and four self-contained essays.Essay I examines the contribution of socio-economic variables to Namibian income inequality. I examine the extent to which total income inequality is due to within-group inequality or between-group inequality. Income inequality in Namibia ranks among the highest in the world. LÄS MER

  4. 4. Family, Neighborhoods, and Health : Conditions for the Development of Human Capabilities

    Författare :Evelina Björkegren; Helena Svaleryd; Hans Grönqvist; Erik Plug; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Health; Inequality; Mortality; Intergenerational Mobility; Birth-order; Neighborhoods; Birth; Childhood; Youth; Capabilities; Education; Economics; Nationalekonomi;

    Sammanfattning : Essay 1: We use data from a large sample of adoptees born in Sweden to decompose the intergenerational persistence in health inequality across generations into one pre-birth component, measured by the biological parents’ longevity, and one post-birth component, measured by the adopting parents’ longevity. We find that most of the health inequality is transmitted via pre-birth factors. LÄS MER

  5. 5. Empirical Essays on Education and Health Policy Evaluation

    Författare :Debbie Lau; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; SAMHÄLLSVETENSKAP; MEDICAL AND HEALTH SCIENCES; SOCIAL SCIENCES; causal inference; register data; segregation; endogamy; iodine deficiency; information campaign; mother tongue education; inequality;

    Sammanfattning : Chapter 1: Impact of School Peers from the Same Region-of-Origin on Endogamy and Work Segregation: Evidence from Sweden This study estimates how the quasi-random variation in the proportion of school peers from the same Region-of-Origin (ROO) affects the probability for an individual to have a partner from the same ROO (endogamy) and the proportion of colleagues from the same ROO in the same workplace later in life (work segregation). This is answered by a fixed effect regression model, together with a unique dataset that merges different register databases from Sweden. LÄS MER
