This thesis presents structural and morphological studies of semiconductor nanostructures, namely quantum dots, nanowires and a dilute ferromagnetic semiconductor. These nanostructures are investigated on the atomic scale using cross-sectional scanning tunneling microscopy (XSTM). Indium arsenide (InAs) quantum dots in both an indium phosphide (InP) and GaAs matrix are studied. The InAs/InP quantu
Politiska organisationer anställer ofta, och i allt högre utsträckning, utredare och andra kunskapsarbetare för att producera kunskap och politiska förslag, och den svenska fackliga centralorganisationen LO har sedan 1930-talet anställt nationalekonomer och andra samhällsvetare. Genom analys- och presentationsmetoder som liknar den akademiska samhällsvetenskapen, och genom interaktion med talesperPolitical organisations routinely, and increasingly, employ researchers to make knowledge claims and suggest political action. Swedish blue-collar trade union organisation LO has done so since the 1930s, employing economists and other social scientists drawing in part on methods of analysis and presentation similar to academic social science, and in part on interaction with spokespersons for trade
This article reviews and develops the recent critique of empiricist quantitative and qualitative methods in social science in general, and leadership studies, in particular. It argues for an interpretive-reflective approach that fully acknowledges the theory-laden, interpretative nature of empirical studies and the ambiguity of ‘data’. In addition the political and historical character of social s
Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1) synthesize these findings, (2) present a conceptual framework that identifies mechanisms and constraints on shrub increase, (3) explore causes, feedbacks and implications of the increased shrub cover in tun
Although the potential advantages of clinical germline genome editing (GGE) over currently available methods are limited, the implementation of GGE in the clinic has been proposed and discussed. Ethical issues related to such an application have been extensively debated, meanwhile, seemingly less attention has been paid to ethical implications of studies which would have to be conducted in order t
Not knowing enough about the similarities or differences of citation structures between different types of publications creates problems related to whether citation maps of research fields based on Web of Science/ISI data are representative of research fields as a whole or if they are a representation of how WoS perceives the field, not the least in the humanities and the social sciences. To inves
The concept of ‘imaginaries’ has gained prominence as a lens for examining how collective orientations shape social and organisational action; yet the meaning of this concept and its relation to neighbouring notions has become so diffuse as to call into question its analytical potential. Addressing this need for clarification, we situate imaginaries within a genealogy of imagination, tracing the cThe concept of ‘imaginaries’ has gained prominence as a lens for examining how collective orientations shape social and organisational action; yet the meaning of this concept and its relation to neighbouring notions has become so diffuse as to call into question its analytical potential.

The symptoms of interstitial cystitis (IC)/bladder pain syndrome (BPS) may have multiple causes and involve many contributing factors. Traditional treatments (intravesical instillations) have had a primary focus on the bladder as origin of symptoms without adequately considering the potential influence of other local (pelvic) or systemic factors. Systemic pharmacological treatments have had modest
There is an increasingly widespread policy momentum to increase patient-centred care and to improve quality of life outcomes within health services. Qualitative research methods are used to elicit in-depth and detailed insights into people's attitudes, beliefs, emotions and experiences - much of which may remain unspoken during clinical encounters. Questions about patients' beliefs and preferences
Rationale: Proinflammatory cytokines have been identified as potential targets for lowering vascular risk. Experimental evidence and Mendelian randomization suggest a role of MCP-1 (monocyte chemoattractant protein-1) in atherosclerosis and stroke. However, data from large-scale observational studies are lacking. Objective: To determine whether circulating levels of MCP-1 are associated with risk
Industry convergence – the merger of hitherto separate industries – is a phenomenon that has had a profound effect on several industries and received considerable interest among practitioners and business press over the past decades. Despite this, industry con- vergence has only received limited attention from the academic management field, al- though an emergent discussion on convergence can be i
The First International Research Workshop on Mesoamerican Nephropathy (MeN) met in Costa Rica in November 2012 to discuss how to establish the extent and degree of MeN, examine relevant causal hypotheses, and focus efforts to control or eliminate the disease burden. MeN describes a devastating epidemic of chronic kidney disease of unknown origin predominantly observed among young male sugarcane cu
Currently, a great deal of biomedical research in fields such as epidemiology, clinical trials and genetics is reliant on vast amounts of biological and phenotypic information collected and assembled in biobanks. While many resources are being invested to ensure that comprehensive and well-organised biobanks are able to provide increased access to, and sharing of biomedical samples and information
This chapter addresses ten “themes” (or conclusions). It starts with conclusions on the various themes that the author has addressed in many articles, books, and reports over the decades. Each conclusion constitutes a section heading, followed by some of the arguments in a much shorter form than when the conclusions were reached originally – over the decades. Therefore, much of the text is heavily
