Situational leadership in air traffic control

In high-risk environments such as air traffic control, leadership on different levels plays a certain role in establishing, promoting, and maintaining a good safety culture. The current study aimed to investigate how leadership styles, leadership style adaptability, and over and under task leadership behavior differed across situations, operative conditions, leadership structures, and working task

The effect of urban geometry on mean radiant temperature under future climate change: a study of three European cities

Future anthropogenic climate change is likely to increase the air temperature (T a ) across Europe and increase the frequency, duration and magnitude of severe heat stress events. Heat stress events are generally associated with clear-sky conditions and high T a , which give rise to high radiant heat load, i.e. mean radiant temperature (T mrt ). In urban environments, T mrt is strongly influenced

Plasma procalcitonin and the risk of cardiovascular events and death: a prospective population-based study.

Objectives: A number of inflammatory biomarkers such as C reactive protein (CRP) are independent predictors of cardiovascular risk. The inflammatory biomarker procalcitonin (PCT) has previously been shown to be associated with coronary atherosclerosis and the metabolic syndrome. We evaluated the ability of PCT to predict future cardiovascular events in a population of apparently healthy individual

MDA in plasma as a biomarker of exposure to pyrolysed MDI-based polyurethane: correlations with estimated cumulated dose and genotype for N-acetylation

The object of this study was to investigate whether exposure of pipe-layers to thermal degradation products of diphenylmethane diisocyanate (MDI) could be assessed by analysing 4,4-methylenedianiline (MDA) in hydrolysed plasma and urine, and whether the genotype for N-acetylation affected these biomarker levels. Blood and urine samples were drawn from 30-pipe-layers who had been welding polyuretha

Context-Dependent Development of Lymphoid Stroma from Adult CD34(+) Adventitial Progenitors.

Despite the key role of primary and secondary lymphoid organ stroma in immunity, our understanding of the heterogeneity and ontogeny of these cells remains limited. Here, we identify a functionally distinct subset of BP3(-)PDPN(+)PDGFRβ(+)/α(+)CD34(+) stromal adventitial cells in both lymph nodes (LNs) and thymus that is located within the vascular niche surrounding PDPN(-)PDGFRβ(+)/α(-)Esam-1(+)I

Essays on Strategy-proof Social Choice

Popular Abstract in Swedish Denna avhandling ger ett bidrag till teorin om strategisäkra kollektiva beslut. I denna teori undersöks under vilka förutsättningar det är möjligt att konstruera omröstningsprocedurer (hädanefter kallade för kollektiva valfunktioner) som är strategisäkra i den bemärkelsen att ingen väljare kan ändra utfallet av en omröstning till sin fördel genom att inte rösta enligt sThis thesis makes a contribution to strategy-proof social choice theory, in which one investigates the conditions under which it is possible to construct social choice functions (i.e., voting procedures) that can never be manipulated in the sense that some voter, by misrepresentation of his true preferences, can change the outcome of a voting and obtain an alternative he prefers to the one that ho

Aligning corporate strategy, procurement strategy and e-procurement tools

This paper presents a framework for assessing alignment between corporate strategy, procurement strategy and purchasing tools. The framework is built on generation of rents as its common denominator for assessing alignment between the levels. Three types of rents are identified: monopoly rents; Ricardian rents and entrepreneurial rents. The framework is then used for assessing the strategic origin

Fluorescence Lidar Multicolor Imaging of Vegetation

Multicolor imaging of vegetation fluorescence following laser excitation is reported for distances of 50 m. A mobile laser-radar system equipped with a Nd:YAG laser transmitter and a 40-cm-diameter telescope was utilized. The laser light was Raman shifted to 397 nm with pulse energies of approximately 30 mJ. An image-intensified CCD camera with a specially designed split-mirror Cassegrainian teles

Use of potentiometric fluorophores in the measurement of mitochondrial reactive oxygen species.

Mitochondrial reactive oxygen species (ROS) are implicated in signal transduction, inflammation, neurodegenerative disorders, and normal aging. Net ROS release by isolated brain mitochondria derived from a mixture of neurons and glia is readily quantified using fluorescent dyes. Measuring intracellular ROS in intact neurons or glia and assigning the origin to mitochondria are far more difficult. I

Individual placement and support - a model to get employed for people with mental illness - the first Swedish report of outcomes.

Scand J Caring Sci; 2011 Individual placement and support - a model to get employed for people with mental illness - the first Swedish report of outcomes Lack of participation in the open labour market is highly prevalent for people with a mental illness across countries, and the proportion of people who get some kind of sickness benefit because of mental illness is steadily growing in Europe.

X-ray - Based Studies of Structural Dynamics in Solids and Liquids

Popular Abstract in Swedish Våglängden för röntgenstrålning är mycket kortare än den för synligt ljus. I själva verket är den jämförbar med avståndet mellan atomer i fasta material, vilket är i storleksordningen en tiondels nanometer. Genom att använda ljus med så kort våglängd är det möjligt att studera materials struktur på atomär nivå. Spridning av röntgenstrålar har utvecklats till ett ovärderThe wavelength of x-ray radiation is much shorter than that of visible light. In fact, it is comparable to the distances between atoms in solids, which is on the order of one tenth of a nanometer. Using light of such a short wavelength, it is possible to study the structure of materials on the atom level. Scattering of x-rays has been developed into an invaluable tool to analyze various characteri
