Research on media and democracy mobilizes a range of conceptual versions of the subject. This is often done implicitly, or out of habit, with a specific model becoming established in any given research tradition. This presentation argues that different theories of the subject can have different implications for our understanding of citizenship and democracy. The text surveys a number of versions,
Abstract in UndeterminedAbstractThe aim of this study is to investigate the structural licensing and the semantics of the dative-DP in ditransitive constructions in German from a cognitive and construction grammar perspective.While the indirect object in constructions with prototypical ditransitive verbs is said to be a lexically selected argument of the verb, the indirect object in beneficiary di
Attosecond pulses allow the study of electrons on their natural timescale. They are created from the interaction of atoms with ultrashort, intense laser pulses whose electric field approaches the strength of inner-atomic electric fields. This thesis presents experiments around the generation, characterization and application of attosecond pulses. First, we study the influence of the atomic genera
Increasing nitrogen(N) deposition due to anthropogenic activities has become a significant global change threat to N-poor terrestrial ecosystems. We compared bacterial growth and nutrients limiting bacterial growth in one of the longest running experiments on increasing N-deposition to a temperate forest, the Chronic Nitrogen Amendment Study at Harvard Forest, USA. Soil samples were collected in f
Popular Abstract in Swedish Intubationer (nedsättande av andningsslang i luftstrupen) i samband med generella anestesier kan påverka lungfunktionen med en sänkt arteriell syresättning (SpO2) som följd. Medel för inhalationsanestesi administreras och elimineras via andningsvägarna. Anestesimedlen tas upp i blodet från lungans alveoler genom diffusion och transporteras löst i blodplasma till hjärnanBackground and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP. Methods: Prospective, randomised, clinical studies. ASA І and II abdominal surgery patie
We report a systematic study of the relationship between crystal quality and electrical properties of InAs nanowires grown by MOVPE and MBE, with crystal structure varying from wurtzite to zinc blende. We find that mixtures of these phases can exhibit up to 2 orders of magnitude higher resistivity than single-phase nanowires, with a temperature-activated transport mechanism. However, it is also fo
Alginate microbeads, produced by emulsion/internal gelation, were studied for the entrapment and microcultivation of microbial cells with biotechnological potential. An anaerobic consortium which was selected for its capacity to degrade complex carbohydrates, and a pure culture of cellulose degrading bacteria were used for entrapment studies. Optimization of conditions for the formation of spheric
In this study a new type of honeycomb-patterned micro-porous polyester fibre was used to develop good moisture absorption and quick drying properties of woven fabrics. Details of the development and after-finish processes of the fabrics were illustrated. The water transport, vapour transmission and quick dry properties of the seven different end products were also investigated. It was evident that
In our previous work, the agreement between the theoretical and measured wavelength for the 4f-M1 transition of Ag-like W shed light on the importance of a careful treatment of all core-valence correlation effects to obtain a reliable value of this fine structure energy separation. To confirm these results and extend the analysis isoelectronically, we have undertaken an experimental and theoretica
The Lund SSAMS machine has been in routine operation since 2004. We present results from the last year of operation of the facility. The reference sample IAEA C7 and the "old" oxalic acid, Oxl, were used as secondary standards. As primary standard for calculations the OxII was used. The background and long term stability of the facility are discussed. We also report on the quality of the C-13/C-12
We are entering a new era with governmental bodies taking an increasingly guiding role, gaining control of registries, demanding direct access with release of open public information for quality comparisons between hospitals. This review is written by physicians and scientists who have worked with the Swedish Knee Arthroplasty Register (SKAR) periodically since it began. It reviews the history of
Commitment to involuntary care is a multistage process comprising many different aspects; legal, psychological, medical, social and ethical among others. It can also be analyzed from the perspective of a continuum starting from the report to the social authorities, the evaluations on whether to commit or not, the actual commitment and aftercare following involuntary treatment. Enhancing knowledge
This study measures the impact of fanya juu terraces on the net value of crop income in a high-rainfall area in the Ethiopian highlands using cross-sectional multiple plot observations. Using propensity score matching methods we find that the net value of crop income for plots with fanya juu terraces is lower than for plots without fanya juu terraces. This finding makes it difficult to avoid concl
The emphasis here is the need to understand both the normative gap and the role of digital architecture in order to display the inherent challenge that copyright meets in a digital society. Consequently, in being a descriptively focused study, this article studies contemporary Hungarian copyright and contrasts this to the findings from a survey with over 500 respondents from the Hungarian file-sha
The interaction of Pt(II)(dppf)-complex, namely [Pt(dppf)(H2O)(2)](2+) with DNA was investigated by DPV and H-1-NMR techniques. The results showed that the interaction process has been characterized by changes in the electrochemical parameters of both compounds and the formation of a new anodic current peak close to the anodic current peak of the [Pt(dppf)(H2O)(2)](2+). In addition, the H-1-NMR sp
Net primary production (NPP) is the difference in gross photosynthetic assimilation of carbon and carbon loss due to autotrophic respiration, and is an important ecosystem variable that facilitates understanding of climate change impacts on terrestrial ecosystem productivity and ecosystem services. The aim of this study is to rapidly estimate the NPP of European potential natural vegetation for cu
The remodeling phase of tissue repair in lung disorders such as idiopathic pulmonary disease, asthma, obliterative bronchiolitis, and after lung transplantation is not well understood. One of the key players in fibrosis is the fibroblast and its progenitor, the fibrocyte. The fibroblast is the main producer of extracellular matrix molecules such as collagen, versican, perlecan, biglycan, and decor
There have been many studies of dipeptide structure at a high level of accuracy using quantum chemical methods. Such calculations are resource-consuming (in terms of memory, CPU and other computational imperatives) which is the reason why most previous studies were restricted to the two simplest amino-acid residue types, glycine and alanine. We improve on this by extending the scope of residue typ
