Distribuerad öppenhet : En studie av konceptualiseringen av öppenhet inom open access-rörelsen
The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.
Sexuell dysfunktion hos kvinnor med diabetes : en sammanställning av tillgängliga mätinstrument
Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.
Iron bioavailability and pro- and prebiotics
Iron deficiency is one of the most frequent micronutrient deficiencies around the world. Low iron bioavailability simultaneously with a high iron requirement is a high risk factor for developing iron deficiency. Probiotics are microorganisms that confer a health benefit on the host. Prebiotics are oligosaccharides which provide a health benefit on the host due to a positive modulation of the microflora in the gut. The aim of this paper is to evaluate if there is a connection between pro-and/or prebiotics and iron bioavailability.
Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields
The pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. There are several examples in the literature of interactions between pathogens where one, or both species, support or increase the damage made by the other organism. These complexes are important to investigate and to be able to forecast, since even low incidences of fungi or nematodes may result in an interaction of significance.
Resan är målet: En kvantitativ studie om kongruenta erbjudandens påverkan på köpintentionen
The technological development and increasing popularity for integrated multichannel solutions constitutes both severe opportunities and challenges for todays' and tomorrows' retailers. On the account of consumers leaving traces when using digital channels and the technological development enabling retailers to use this information to create relevant offers, goal-congruity is relevant to apply in the multichannel shopping context. Based upon previous research on goal congruity and channel integration, our main purpose in this study is to increase the understanding for how congruity in an offer increases the intention to redeem the offer. Several studies focus on and contrast the product characteristics hedonic and utilitarian. However, it has been stated that it is crucial that research also examines the difference in target audience, buying situation and as examined in this study: buying decision process.
DEN ANDREIdentitetskonstruktioner i förhållande till skolnormen : - Vuxnas berättelser om sin tidigare skolgång
AbstractWe decided to explore former school pupils? experiences of not conforming to the norm. Earlier studies have focused on the children as ?the problem?. We see this as worrying, especially since there is very little research focusing on the pupils? own experiences. The children?s own perspective needs to be brought to the fore.

Inflammatory cytokines induced by Bovine Viral Diarrhoea Virus (BVDV) in Peripheral Blood Mononuclear Cell (PBMC) subsets
Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.
Representativ valdemokrati? : Gör den valdemokratiska idealtypen rättvisa åt den representativa demokratin?
In modern, Swedish political science there are different ways of looking at ?democracy?. A very common distinction is that between three groups of democratic theories: electoral democracy, participation democracy and deliberative democracy.The nowadays frequently used concept of electoral democracy is often used as synonymous with the older concept of representative or indirect democracy ? frequently regarded as a contrast to the direct democracy of ancient Athens. However, there are also important differences.
Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?
Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.
Novel anticancer combination therapies using replication-selective oncolytic adenoviruses and chemotherapeutics : investigating cell death mechanisms
Den här studien genomfördes i Helsingborgs kommun som ett examensarbete inom livsmedelstillsynsprogrammet på Lantbruksuniversitet (SLU) i Uppsala. Idén med uppsatsen uppkom efter att författaren deltagit i ett möte på miljökontoret i Helsingborg. En kontroll som gjorts bland livsmedelsbutiker i kommunen visade att 60 % av livsmedelsbutikerna fick underkänt vid inspektioner. De områden som fick flest anmärkningar var rengöring och underhåll av lokaler och utrustning, internrevision och temperaturer i kylar och frysar. Över hälften av butikerna fick underkänt vid kontrollen vilket visar på att det uppenbarligen finns brister i egenkontrollen.
Canine S- and M/L- cone electroretinograms
Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989).
Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).
Metodik för resistenstest i renkavle : en studie om herbicidresistens; mekanismer, detektion och åtgärder
Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.
Möte med ett okänt musikstycke Musikhögskolestudenters strategier när de ska bilda sig en uppfattning om ett nytt musikverk utifrån ett fonogram eller en notbild
Title: An encounter with an unknown piece of music. This essay describes the mechanisms involved in musical interpretation, by studying a score and listening to a recording. I have tried to map processes dealing with listening and score reading through an experiment, in which students from the Malmö Academy of Music were presented with a novel piece of music. I have made some conclusions, for instance it seems as though there is a connection in the interpretation between musical complexity and tempo, and a connection between dynamics and pitch, moreover that the participants in this study seem to be affected by the interpretational practice at the Malmö Academy of Music. The study is qualitative in its design both regarding data collection and interpretation of data.
Det allmännas skadeståndsansvar : Skadeståndsansvar för ideell skada enligt frihetsberövandelagen
BACKGROUND: Today?s societal changes, including high rate of change and increasing information flows, are increasing the demand on the individual mental capacity. It becomes increasingly difficult to analytically process all the different dilemmas and everyday decisions as individuals have a limited mental capacity available to make these decisions. Thus, it has been suggested that ego-depleted relies more heavily on intuition, which is less burdensome, when making decision. However little is known about to what extent intuitive decisions differ from analytic.
