  2. 1. Pointwise and Genomewide Significance Calculations in Gene Mapping through Nonparametric Linkage Analysis: Theory, Algorithms and Applications

    Author : Lars Ängquist; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; programming; actuarial mathematics; Statistik; cytogenetics; Genetik; cytogenetik; Mathematics; Matematik; Statistics; operations research; Genetics; ROC curves; conditioning loci; optimal score functions; noncentrality parameter; cost adjusted relative efficiency; exponential tilting; importance sampling; Monte Carlo simulation; normal approximation; crossover rate; process maximum; analytical approximation; significance calculations; NPL score; conditional linkage analysis; two-locus linkage analysis; Allele sharing; aktuariematematik; operationsanalys; programmering; gene-gene interaction; composite hypotheses; genetic disease models; classes of score functions; nonparametric linkage analysis;

    Abstract : In linkage analysis or, in a wider sense, gene mapping one searches for disease loci along a genome. This is done by observing so called marker genotypes (alleles) and phenotypes (affecteds/unaffecteds) of a pedigree set, i.e. READ MORE

  4. 2. Computational Medical Image Analysis : With a Focus on Real-Time fMRI and Non-Parametric Statistics

    Author : Anders Eklund; Hans Knutsson; Mats Andersson; Stephen LaConte; Linköpings universitet; []
    Keywords : functional magnetic resonance imaging; brain computer interfaces; canonical correlation analysis; random permutation test; graphics processing unit;

    Abstract : Functional magnetic resonance imaging (fMRI) is a prime example of multi-disciplinary research. Without the beautiful physics of MRI, there wouldnot be any images to look at in the first place. To obtain images of goodquality, it is necessary to fully understand the concepts of the frequencydomain. READ MORE

  5. 3. Active and healthy ageing in Europe : significance of social relationships

    Author : Septi Kurnia Lestari; Nawi Ng; Xavier de Luna; Malin Eriksson; Mikael Rostila; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; older population; ageing; social relationships; social support; social participation; social contact; quality of life; frailty; panel data; latent class analysis; growth model; multilevel logistic regression; pandemic; Europe; SHARE; äldre befolkning; åldrande; sociala relationer; socialt stöd; socialt deltagande; sociala kontakter; livskvalitet; åldersskörhet; paneldata; latent klassanalys; tillväxtmodell; flernivålogistisk regression; pandemi; Europa; SHARE; epidemiologi; Epidemiology; Public health; folkhälsa;

    Abstract : Background: Social relationships have important roles in achieving active and healthy ageing. Social relationships are dynamic across the life course. A myriad of contextual and individual (e.g. READ MORE

  6. 4. Juvenile Crime in Context : The Significance of School Affiliation

    Author : Julia Sandahl; Tove Pettersson; Bitte Modin; Robert Svensson; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Juvenile crime; School context; Socio-structural approach; Multilevel analysis; Contextual theories of crime; kriminologi; Criminology;

    Abstract : Within criminology, research on the school-crime relationship has been dominated by individual-level theories and methods. This thesis contributes to the relatively scarce literature focused on the socio-structural aspects of juvenile crime by applying a multidimensional approach to the urban school context of Stockholm.

  7. 5. Morphometric analysis of Cambrian fossils and its evolutionary significance

    Author : Illiam Jackson; Graham Budd; Jorijntje Henderiks; Richard Mann; Nigel Hughes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extended Evolutionary Synthesis; phenotypic plasticity; genetic assimilation; phenotypic accommodation; Agnostus pisiformis; Mackinnonia; elliptical fourier analysis; species concept;

    Abstract : The Extended Evolutionary Synthesis (EES) is currently emerging as a theoretical alternative to the Modern Synthesis (MS) in which to frame evolutionary observations and interpretations. These alternative frameworks differ fundamentally in their understanding of the relative roles of the genotype, phenotype, development and environment in evolutionary processes and patterns. READ MORE
