  2. 1. Activation Programs, Benefit Take-Up, and Labor Market Attachment

    Author : Anna Persson; Matz Dahlberg; Eva Mörk; Anders Björklund; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social asssitance; activation programs; workfare; job displacement; Economics; Nationalekonomi;

    Abstract : Essay 1 (with Ulrika Vikman): Previous literature shows that activation requirements for welfare participants reduce welfare participation, but the dynamics behind these results have not been fully examined. In this paper we use a rich set of register data covering the entire working age population in a Swedish municipality to study how the introduction of mandatory activation programs aimed at unemployed welfare participants affect the probability of entering and exiting welfare.

  4. 2. CYP2C19 and brain development : implications for susceptibility to anxiety in a transgenic mouse model

    Author : Anna Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The cytochrome P450-2C19 enzyme is involved in the metabolism of about 10 % of all drugs used today and displays high genetic polymorphism, causing absent, decreased or elevated enzyme activity that divides the population into different metabolic phenotypes. CYP2C19 enzymatic activity is also highly influenced by different substances including drugs and in vivo studies have shown that estradiol and 17α-ethinylestradiol, commonly used in hormone replacement therapy and oral contraceptives, decreased CYP2C19 mediated metabolism in vivo in humans.

  5. 3. Downstream Processing Using Membrane Technology

    Author : Anna Persson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Biochemical technology; Chemical technology and engineering; Protein A; Bovine serum albumin; Lactic acid; Electrodialysis; Ultrafiltration; Microfiltration; Downstream processing; Membrane; Biokemisk teknik;

    Abstract : Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. READ MORE

  6. 4. Effects of landscape context on populations of bumblebees

    Author : Anna Persson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Apoidea; Bombus; Campanula; agriculture; land-use intensity; complexity; garden; grassland; field border; MFC; pollination; Factor Analysis;

    Abstract : To investigate recent declines in bumblebee populations, I carried out landscape analyses, made field studies of bumblebees, flowering plants and pollination in an agricultural region in southernmost Sweden. Studies were carried out in landscapes of contrasting agricultural intensity and land-cover configuration; "simple" landscapes highly dominated by large crop fields, and "complex" with mixed farming, grasslands and smaller fields.

  7. 5. Exploring textiles as materials for interaction design

    Author : Anna Persson; Högskolan i Borås; []
    Keywords : HUMANIORA; HUMANITIES; interaction; design; textiles; materials; Textiles and fashion; Textiles and Fashion General ; Textil och mode generell ;

    Abstract : As computational technology and new materials enter the world of textiles, our view on textile materials is challenged. Textile interaction design suggests a new design space in which the fields of textile design and interaction design are merged. READ MORE
