  1. 21. Understanding Intergenerational Mobility : Inequality, Student Aid and Nature-Nurture Interactions

    Författare :Gunnar Brandén; Mikael Lindahl; Björn Öckert; Erik Lindqvist; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intergenerational mobility; inequality; student aid; adult education; difference-in-differences; propensity scores; Economics; Nationalekonomi;

    Sammanfattning : Essay I: A body of evidence has emerged in the literature on intergenerational mobility documenting that unequal countries experience less social mobility: a relationship known as the Great Gatsby Curve. In this paper I estimate the Great Gatsby Curve within Sweden across 125 commuting zones and 20 cohorts, exploiting both cross-sectional and longitudinal variation. LÄS MER

  3. 22. Understanding Task Parallelism : Providing insight into scheduling, memory, and performance for CPUs and Graphics

    Författare :Germán Ceballos; David Black-Schaffer; Erik Hagersten; Samuel Thibault; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Task-based programming; Task Scheduling; Analytical Cache Model; Scheduling; Runtime Systems; Computer Graphics rendering ; Computer Science; Datavetenskap;

    Sammanfattning : Maximizing the performance of computer systems while making them more energy efficient is vital for future developments in engineering, medicine, entertainment, etc. However, the increasing complexity of software, hardware, and their interactions makes this task difficult.

  4. 23. Understanding the Noise : Spliceosomal snRNA Profiling

    Författare :Lei Liu Conze; Anders Virtanen; Lars Wieslander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ncRNA; snRNA; U1; splice site; alternative splicing; high-throughput sequencing; 454; SNP; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : The concept of the gene has been constantly challenged by new discoveries in the life sciences. Recent challenging observations include the high frequency of alternative splicing events and the common transcription of non-protein-coding-RNAs (ncRNAs) from the genome. The latter has long been considered noise in biological systems. LÄS MER

  5. 24. Understanding Firm Behavior : The Role of Recruitments and Institutional Reforms

    Författare :Anton Nyrenström Gidehag; Sven-Olov Daunfeldt; Dan Johansson; Niklas Rudholm; Christian Bjørnskov; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Recruitment; knowledge spillover; labor cost; labor demand; employment; immigrants; payroll tax; wages; tax evasion;

    Sammanfattning : The topic of this thesis is firm behavior and how it is shaped by institutional changes and firms’ recruitment decisions.The first essay studies how the recruitment decisions made by small and medium-sized enterprises (SMEs) affect their subsequent productivity development.

  7. 25. Understanding Certificate Revocation

    Författare :Åsa Hagström; Robert Forchheimer; Ingemar Ingemarsson; Håkan Kvarnström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Revocation; Public-key certificates; Graph transformation; Information science; Informationslära;

    Sammanfattning : Correct certificate revocation practices are essential to each public-key infrastructure. While there exist a number of protocols to achieve revocation in PKI systems, there has been very little work on the theory behind it: Which different types of revocation can be identified? What is the intended effect of a specific revocation type to the knowledge base of each entity?As a first step towards a methodology for the development of reliable models, we present a graph-based formalism for specification and reasoning about the distribution and revocation of public keys and certificates.
