  1. 1. Voters' Perceptions of Party Politics - A Multilevel Approach

    Författare :Stefan Dahlberg; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Policy representation; voter perceptions; voting behavior; left-right ideology; perceptual agreement; political parties; party systems; electoral systems; institutions; multilevel;

    Sammanfattning : Modern representative democracies are often described as government by the consent of the governed rather than government by the people. Elections play a central role in this context and several theorists of modern democracy have struggled to determine the circumstances under which effective political representation can exist.

  3. 2. Social Capital and Self-rated Health: testing association with longitudinal and multilevel methodologies

    Författare :Giuseppe Nicola Giordano; Socialmedicin och hälsopolitik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Temporal relationships; Multilevel; Longitudinal; Participation; Trust; Self-rated health; United Kingdom; Social capital;

    Sammanfattning : Since Durkheim’s seminal work over a century ago, research has repeatedly shown that individuals with higher levels of social integration, social networks and social support have better health status. However, the recent introduction of a contextual phenomenon known as social capital to the field of public health has sparked lively debate as to how it may also influence the health of individuals, if at all.

  4. 3. Country of birth and socioeconomic disparities in utilisation of health care and disability pensions - a multilevel approach

    Författare :Anders Beckman; Allmänmedicin och samhällsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disability pension; Utilisation of health care; Country of birth; Socioeconomic; Multilevel; Public health; medical training; General practice; epidemiologi; medicinsk utbildning; epidemiology; Folkhälsa; Allmän medicinsk utövning;

    Sammanfattning : Besides individual characteristics, people born in the same country may present a related pattern of health status and health care utilisation, perhaps because they share a number of socioeconomic and cultural characteristics in addition to their common geographic origin and language. Rather than using simple ethnical or geographical categories, we apply multilevel regression analysis with individuals nested within countries of birth. LÄS MER

  5. 4. Domestic violence against women in rural Indonesia : searching for multilevel prevention

    Författare :Elli Nur Hayati; Malin Eriksson; Maria Emmelin; Ulf Högberg; Mohammad Hakimi; Gunilla Krantz; Umeå universitet; []

    Sammanfattning : Modular battery systems based on multilevel inverter (MLI) topologies can possibly overcome some shortcomings of two-level inverters when used for vehicle propulsion. The results presented in this thesis aim to point out the advantages and disadvantages, as well as the technical challenges, of modular vehicle battery systems based on MLIs in comparison to a conventional, two-level IGBT inverter drivetrain.
