Over the last several decades, the light-harvesting protein complexes of purple bacteria have been among the most popular model systems for energy transport in excitonic systems in the weak and intermediate intermolecular coupling regime. Despite this extensive body of scientific work, significant questions regarding the excitonic states and the photo-induced dynamics remain. Here, we address the

Fluorescence decay measurements of the rate of non-radiative direct energy transfer have been employed to characterize the core and the core-corona interface of polyisoprene-poly(methyl methacrylate) (PI-PMMA) diblock copolymer micelles in acetonitrile. These micelles consist of a core of the insoluble PI blocks and a corona of the soluble PMMA blocks. The block copolymers are labeled, at the bloc

Contemporary management increasingly acknowledges that employees have an important responsibility for communication. In employees’ interactions with supervisors, colleagues, and external stakeholders, they actively participate in the co-construction of everything from the organization’s internal communication climate, to the brand and reputation of the organization. This case encourages students t

Background: The relationship between animal ethics orientations and consumer demand for meat with high standards of animal welfare, and the way this relationship plays out in different countries, is not well understood. Using pork as a case study, this comparative study aims to identify the animal ethics orientations that drive purchases of welfare meat in Denmark, Germany, andSweden.

It has repeatedly been shown that consumers consider the higher price of organic produce to be a barrier to buying organic food products. The present paper therefore asks whether organic consumption affects consumers’ actual total food expenditures. Food purchase data for a panel of Danish households during 2006–2014 were used to compare the total food expenditures of different organic household sIt has repeatedly been shown that consumers consider the higher price of organic produce to be a barrier to buying organic food products.

Breast cancer is an important cause of disease-burden and death in women. To prevent over- and undertreatment of breast cancer patients, new prognostic and predictive factors are needed. We aimed to study associations between prognosis and body constitution, genetic factors, and tumor-specific protein levels related to metabolic pathways, and to examine the prognostic impact of statin use and body

Since the terrorist attacks of 9/11, scholars have increasingly turned their attention to the rise and influence of jihadi Salafism. For the most part, though, the focus of this body of work has been on the sociology and activities of organizations such as al-Qaʿeda (AQ) and the Islamic State (IS), with less attention paid to the details of the movements’ ideologies.This, however, should not sugge

This study shows that the production of industrial and commercial waste should form part of normal organisational practices. When asked about waste prevention, representatives of food, textile, electronics and construction companies in Sweden have difficulties highlighting concrete waste-prevention objectives, measures and outcomes. Instead, they highlight economic, technical, and organisational b

Many contemporary scholars have recently defended the idea that the agency of things is symmetrical and equivalent to human agency. We propose an alternative approach to artefacts’ agency based on a field study concerned with contextually situated observations of the process of design of artefacts in Amazonia. By means of participant observation and interviews, we address the role of artefacts in

Sabotera gasledningar, menar Andreas Malm. Vänta på ”riktig kris”, menar Alf Hornborg. Men det duger inte. Lösningen är att fortsätta agera kollektivt genom civilsamhället med olika metoder för att mobilisera bredare massor och sätta press på makthavare, skriver forskare vid Lunds universitet.

Background. The symptoms of obsessive-compulsive disorder (OCD) are highly heterogeneous and it is unclear what is the optimal way to conceptualize this heterogeneity. This study aimed to establish a comprehensive symptom structure model of OCD across the lifespan using factor and network analytic techniques.Methods. A large multinational cohort of well-characterized children, adolescents, and adu

Turkey is in search of a new social contract premised on an extensive revision of the country's Kemalist inheritance and incorporating the economic and political transformations set in motion in the Ozal period. This is not a straightforward task for the reformist forces in Turkish politics and civil society; the imperative and nature of reform are the object of contestation between those factions

This thesis is intended to make a contribution to ongoing efforts to enhance our understanding of the “popular” in the study of politics through a critical examination of the uses and constructions of the people in Turkish politics since the establishment of the Turkish Republic in 1923, to the present in order to distinguish between different modalities of appeals to the “people” and their implic

Background. Pernicious anemia (PA) is an autoimmune disease (AID) which is caused by lack of vitamin B12 (cobalamin) due to its impaired uptake. PA is a multifactorial disease which is associated with a number of other AID comorbidities and which is manifested as part of autoimmune polyglandular syndrome. Due to the shortage of family studies on PA, we planned to address the problem by assessing f
