The thesis sets out to investigate the research question “Does subject certification affect student achievement in mathematics?” By using data from an international large-scale assessment of student skills, Trends in International Mathematics and Science Study (TIMSS), the thesis uses student achievement scores in mathematics as the dependent variable in a series of multiple linear regression mode
The purpose of this study was to examine the relation between technostress, performance based self-esteem (PBS) and burnout among employees, further if technostress beyond PBS could act as a predictor for burnout. The participants in the study were white collar workers from a Swedish manufacturing industry who on a daily basis were using computer and information technology in their work. These com
Butterflies have been systematically monitored in Europe for several decades using standard protocols that are now adopted in over 30 countries. Butterflies are ideal biological indicators: they are well-documented, measurable, sensitive to environmental change, occur in a wide range of habitat types, represent many other insects, and are popular with the public because of their beauty.Records froExecutive Summary Butterflies have been systematically monitored in Europe for several decades using standard protocols that are now adopted in over 30 countries.

There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. Here we show that, while the contribution of wild bees to crop production is significant, service delivery is
Popular Abstract in English Fruits are a key complement to the diet of many people in the southern region of Africa, especially in rural areas. maphilwa (Vangueria infausta L.), maçanica (Ziziphus mauritiana), maçala (Strychnos spinosa), mapsincha (Salacia kraussi), cajú (Anacardium accidentale L.), mavungwa (Landolpia kirki) are some of the most commonly found fruits in sub-Saharan Africa, particThis study concerns the identification and characterisation of volatile components of fruits, and evaluation of the effect of heat treatment and drying on retention or loss of volatiles of fruits. The investigation included developing a procedure to extract volatile components from the fruit matrix, a purification step, separation, identification and quantification. Initial experiments with Vangue
Peatlands play an important role in the global carbon cycle as they contain a large soil carbon stock. However, current climate change could potentially shift peatlands from being carbon sinks to carbon sources. Remote sensing methods provide an opportunity to monitor carbon dioxide (CO2) exchange in peatland ecosystems at large scales under these changing conditions. In this study, we developed ePeatlands play an important role in the global carbon cycle as they contain a large soil carbon stock.

Exercise is considered to be a "medicine" due to its modulatory roles in metabolic disorders such as diabetes and obesity. The intensity and duration of exercise determine the mechanism of energy production by various tissues of the body, especially by muscles, in which the requirement for adenosine triphosphate (ATP) increases by as much as 100-fold. Naturally, athletes try to improve their exerc
Background Despite a large descriptive literature linking creativity and risk for psychiatric illness, the magnitude and specificity of this relationship remain controversial. Methods We examined, in 1 137 354 native Swedes with one of 59 3-digit official and objective occupational codes in managerial and educated classes, their familial genetic risk score (FGRS) for ten major disorders, calculate
Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies have made possible to obtain very low emittance electron beams, which together with the use of undulators allow to guide a very high photon flux into a very small beam size required by the experiments. Development of sources has been accompanied with eq
Commercialization has been recognized as one of the most difficult phases of the innovation process. Failure rates are high, even for products with the potential to address real needs and deliver real customer value. This master's thesis explores commercialization in an even more challenging business context than the typical case. First, the innovating company is an early startup with limited
Comprehensive experimental knowledge of the 62Zn nucleus has been obtained from the combined statistics of four different experiments. The Gammasphere Ge-detector array in conjunction with the 4pi charged-particle detector array Microball was used to detect the gamma-rays in coincidence with evaporated light charged particles. In total twenty seven band structures have been observed in 62Zn, twent
A simple and direct method based on hollow fibresupported liquid membrane (HFSLM) extraction and liquid chromatography equipped with a UV detector was developed for analysis and quantification of parabens in cosmetic products. The parabens analysed included methyl, ethyl, propyl, isobutyl and butyl paraben. The HFSLM extraction was carried out by employing di-n-hexyl ether as organic liquid that w
The purpose of this work was to present collective data on firefighter fatalities in Sweden between 1937 and 2016. Data presented is directly related to operations only. Fatalities due to long-term exposure of gases, particles, and physical/psychological stress or similar were not included in the study. Also, accidents involving ambulances as well as fatalities in direct relation to physical train
Distraction is an emotion regulation strategy that has an ambiguous status within cognitive-behavior therapy. According to some treatment protocols it is counterproductive, whereas according to other protocols it is seen as a quite useful strategy. The main purpose of the present study was to test the hypothesis that distraction is adaptive when combined with active acceptance, but maladaptive whe
