  1. 1. Children’s Peer Status and Their Adjustment in Adolescence and Adulthood : Developmental issues in sociometric research

    Författare :Peter Zettergren; Lars R. Bergman; Thomas W. Farmer; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sociometric peer status; classification; stability; cluster analysis; longitudinal; long-term adjustment; childhood; adolescence; adulthood; Psychology; Psykologi; psykologi; Psychology;

    Sammanfattning : The present research intended to examine the relationship between childhood stable peer status and adjustment in midadolescence for both genders, and adjustment in early and middle adulthood for women. One-year stably peer rejected, popular, and average boys and girls were identified by an age 10 and age 11 sociometric classification procedure using positive nominations and rank-ordering. LÄS MER

  3. 2. Silencing and DNA double-strand break repair in budding yeast

    Författare :Andreas Kegel; Stefan Åström; Stephan Marcand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silencing; Reb1; DSB; NHEJ; Nej1; illegitimate recombination; yeast; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : Transcriptional silencing that makes large chromosomal domains inaccessible for the transcriptional apparatus is nucleated at DNA elements called silencers. In K.lactis a 102bp HMLα silencer was defined revealing three distinct protein-binding regions (A, B, and C) that were required for silencing of HMLα. LÄS MER

  4. 3. Epigenetic Control of Mammalian Development : Studies on an imprinting control region

    Författare :Liang Liu; Pärt Peterson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Epigenetic; Genomic imprinting; DNA methylation; Igf2; H19; Insulator; CTCF; Imprinting control region; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; zoologisk utvecklingsbiologi; Animal Development;

    Sammanfattning : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. LÄS MER

  5. 4. Comparative Genomics of Endosymbiotic Bacteria

    Författare :Ivica Tamas; Paul Baumann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; comparative genomics; endosymbiotic bacteria; Buchnera; reductive evolution; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Genomes of intracellular bacteria are thought to be the products of reductive evolution. They have evolved from ancestral genomes of free-living bacteria through a process of massive gene loss. LÄS MER

  7. 5. A developmental perspective on psychopathic traits in adolescence

    Författare :Selma Salihovic; Margaret Kerr; Henrik Andershed; Randall. T. Salekin; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; psychopathic traits; adolescents; development; stability; change; parental behavior; subgroups; parenting; Psychology; Psykologi;

    Sammanfattning : More than half of known crime is committed by 5-6% of the criminal population. Who are these people? Research has shown that it is likely that a majority of these individuals are characterized by having a psychopathic personality. Interestingly, research has shown that psychopathic features are not unique to adults. LÄS MER
