  1. 1. Towards a Road Safety Development Index (RSDI) : Development of an International Index to Measure Road Safety Performance

    Författare :Ghazwan Al Haji; Kenneth Asp; Linköpings universitet; []
    Nyckelord :Technology; Road safety; RSDI; ASEAN; international comparisons; Human Development; Index; ranking; principal components; composite indicators; macro-performance indicators; macro-models; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Aim. This study suggests a set of methodologies to combine different indicators of road safety into a single index. The RSDI is a simple and quick composite index, which may become a significant measurement in comparing, ranking and determining road safety levels in different countries and regions worldwide.

  3. 2. Psychological distress in coronary heart disease : Risk indicators, treatment and cardiovascular prognosis

    Författare :Fredrika Norlund; Claes Held; Erik Olsson; Petra Lindfors; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; psychological distress; myocardial infarction; coronary heart disease; depression; anxiety; stress; cognitive behavioral therapy; iCBT; stress management; cardiac rehabilitation; Psychology; Psykologi;

    Sammanfattning : The aims of this thesis were to: (1) explore factors associated with emotional distress; (2) investigate psychosocial stress as a risk factor for cardiovascular (CV) morbidity in patients with coronary heart disease (CHD); (3) investigate the impact of group-based stress management on psychological outcomes, and if that mediates risk of CV events; and (4) evaluate an internet-based cognitive behavioral therapy (iCBT) for emotional distress in patients with a recent myocardial infarction (MI).In Study I, data from the national registry SWEDEHEART on 27,267 MI patients < 75 years was used.

  4. 3. Lignocellulose Biocomposites– A Comparison of Wood Fibers and Microfibrillated Lignocellulose

    Författare :Erfan Oliaei; Lars Berglund; Tom S. C. Lindström; Fredrik Berthold; ‪Maria Soledad Peresin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : All-lignocellulose composites, meaning densified fiber or fibril materials without added binder, show interesting mechanical properties and can be eco-friendly. Composites based on hot-pressed microfibrillated lignocellulose (MFLC) and lignocellulosic wood fiber (WF) reinforcements are compared with respect to processing, structure, mechanical properties, and eco-indicators.

  5. 4. Psychometric studies of the Swedish version of the Adolescent Drug Abuse Diagnosis (ADAD) instrument

    Författare :Josefine Börjesson; Helene Ybrandt; Bengt-Åke Armelius; Anders Tengström; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ADAD; validity; reliability; assessment; psychometric; severity index; composite score; normal; antisocial adolescents; psychological health;

    Sammanfattning : This thesis describes studies into the psychometric properties of a Swedish language version of the Adolescent Drug Abuse Diagnosis (ADAD) instrument. The psychometric properties of this instrument have been examined in two previous studies: an American study was conducted by the developers of the interview, Friedman and Utada (1989), and a Swiss study was undertaken by Bolognini et al.

  7. 5. On-site sanitation systems - An integrated assessment of treatment efficiency and sustainability

    Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Arve Heistad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small-scale; sand filter; phosphorus filter; package plant; blackwater; greywater; urine diversion; multi-criteria; composite sample; VA-teknik; Urban Water Engineering;

    Sammanfattning : Small on-site sanitation systems for wastewater collection and treatment are prevalent in suburban and rural areas in many countries. However, these systems often underperform, causing potential impact to the receiving waters and increasing the risks to public health, thus hindering the overall sustainability of the systems. LÄS MER
