Det huvudsakliga syftet med min uppsats var att läsa Brott och straff (1866) i en kristen teologisk kontext, där jag ville undersöka om de två trosinriktningarna i romanen förenades eller inte. Jag tog min utgångspunkt i att Raskolnikov gav uttryck för föreställningar inom Gud-är-död-teologin med betoning på Simone Weil och William Hamilton, och att Sonja gav uttryck för föreställningar inom den rysk-ortodoxa teologin. Vidare formulerade jag frågan: Kan man läsa Brott och straff som en egen gren inom kristen teologi? Jag tog hjälp av identitetsrekonstruktion som metod, med fokus på Ruard Ganzevoorts användning av termen. Resultatet är att man faktiskt kan läsa Brott och straff som en egen gren inom kristen teologi. Både Raskolnikov och Sonja har fått något i utbyte av varandra och sålunda rekonstruerat sina tidigare övertygelser och trosuppfattningar. Raskolnikovs identitet, som tidigare präglades av en övermänniskoteori och föreställningen om att Gud kanske inte finns, har påverkats av mötet med Sonja och övergett sina tidigare trosuppfattningar. Han har börjat tro. Sonja har också genomgått en förändring. Mötet med Raskolnikov har lett till att hon har börjat betrakta verkligheten med ett realistiskt synsätt. Hon har även kommit till insikt om att lidandet är ett ofrånkomligt faktum. Resultatet av den teologiska föreningen leder till en ny sorts teologi, som jag valt att kalla hoppets teologi. En teologi som förenar föreställningar från båda trosinriktningar.

Syftet med min uppsats var att undersöka hur elever med dyslexi i grundskolans senare år och deras IT-användning påverkas av att den svenska grundskolan arbetar med att inkludera dem i det vanliga klassrummet. I denna undersökning har jag valt att använda mig av en litteraturstudie där jag studerat vad andra forskare har skrivit samt rapporter som publicerats på Skolverkets hemsida. Tidigare och nyare skollagar har även de studerats. I resultatet har det kommit fram att elever med dyslexi känner sig stressade att bli klara fort med sina arbetsuppgifter om de måste dela på en dator. Det har även visat sig att det går i genomsnitt sex elever per dator, vilket leder till att elever med dyslexi kan hamna i stressade situationer. Negativa attityder från klassläraren kan påverka dem negativt på ett sätt som gör att IT-användningen uteblir för elever med dyslexi om de inkluderas i klassrummet. Men en del av lärarna anser att datorn hjälper dem att anpassa sin undervisning efter elever i behov av särskilt stöd.

O estudo da responsabilidade civil dos administradores de companhias abertas na doutrina nacional trata usualmente dos deveres fiduciários, do ato regular de gestão e da teoria ultra vires, da culpa ou dolo do administrador, das ações ut universi e ut singuli e da solidariedade entre a responsabilidade do administrador e a da companhia. Poucos abordam as causas extintivas dessa responsabilidade, e raro são os que tratam da hipótese de exclusão de responsabilidade do artigo 159, § 6º, da Lei nº 6.404/76. Como a disciplina dos deveres fiduciários prevista na lei societária brasileira tem forte influência do Direito norte-americano, buscou-se na legislação, doutrina e jurisprudência daquele país os fundamentos necessários à melhor interpretação e aplicação da regra de exclusão e, em especial, na business judgment rule, doutrina que protege os administradores contra responsabilização por prejuízos à companhia decorrentes de decisões por eles adotadas, proteção esta também conferida pela hipótese do artigo 159, § 6º, da Lei nº 6.404/76, ao administrador leal e de boa-fé.

In this paper, we compare a well-known semantic spacemodel, Latent Semantic Analysis (LSA) with another model, Hyperspace Analogue to Language (HAL) which is widely used in different area, especially in automatic query refinement. We conduct this comparative analysis to prove our hypothesis that with respect to ability of extracting the lexical information from a corpus of text, LSA is quite similar to HAL. We regard HAL and LSA as black boxes. Through a Pearsonrsquos correlation analysis to the outputs of these two black boxes, we conclude that LSA highly co-relates with HAL and thus there is a justification that LSA and HAL can potentially play a similar role in the area of facilitating automatic query refinement. This paper evaluates LSA in a new application area and contributes an effective way to compare different semantic space models.

Many immigrants in Sweden have not had the chance to learn to read and write, for various reasons. In Sweden, literacy is a prerequisite to being able to function in the cultural community, and for many immigrants this is the first time that they experience their inability to read and write as a handicap or see themselves as “illiterate”. The aim of this study is to use a socio-cultural, second language and gender approach to describe, analyse and understand how a number of adult, illiterate, immigrant women experience their situation when they are expected to simultaneously learn to speak, read and write Swedish. The study focuses on two literacy groups in two Swedish municipalities. In one of the groups I act as both teacher and researcher. The thesis is a case study of the learning process of five illiterate immigrant women in Sweden. The results are based on interviews, carried out with the help of an interpreter, and observation of teaching and texts ritten by the students. The study is based on the assumption that human learning is an activity that takes place in a cultural community in a social context. When learning a language, the language is simultaneously the tool that facilitates social communication and the object of the learning process. The study shows that cultural communities influence the women in different ways. Gender structures are firmly planted in a patriarchal value system, which means that women are seen as inferior to men, and women are expected to “meet the demands of others”. The women have no time to study at home, as their household duties are prioritised. However, there are subtle indications that there is a wish to change the situation in accordance with Swedish values and norms. This can be seen in the Swedish for Immigrants (SFI) lessons. As they have little contact with Swedes, school is the only arena in which they have a chance to use Swedish. They are positive towards teaching and school as an institution. Here they are able to develop an alternative identity. The study also shows that teaching in the literacy groups is to a great extent based on a technical approach, in which the teacher tries to elicit a correct answer from the students. Social interaction involving contemplation and negotiation is either not included or not prioritised. the women’s experience and knowledge is not made use of. There are,however, occasions when collaborative discussions take place between the teacher and students. On these occasions an exchange of experiences takes place. Learning is based on the students’ own experiences and thoughts. Linguistic concepts gain meaning in the collaborative discussion. Initially the concepts may be unclear, but the group works on them together, adapting and adjusting them until they finally make sense. Finally, I conclude that women immigrants bring their own socio-cultural values and experience to the school situation, which affects their learning process to varying degrees. Furthermore, immigrant women need more time at school, as it is the only arena in which they can spend time on studying and personal development. another conclusion is that the school must become a learning community that recognises the immigrants’ cultures, makes use of the students’ experience and allows the students to participate in collaborative discussions, so that they can develop their ability to speak, read and write Swedish.

Litteraturstudien behandlar skönlitteratur i undervisning, vilka effekter den har samt varför skönlitteratur bör läsas i skolan. Syftet med litteraturstudien är att kartlägga skönlitteraturens roll i undervisningen samt synliggöra dess möjligheter. Frågeställningar som används är: Vilka faktorer påverkar läsning?; Varför ska skönlitteratur läsas i skolan?; Hur används skönlitteratur i undervisning och vad ger det för effekter? Studien är en litteraturstudie där datainsamling av texter gjorts utifrån tidigare nämnt syfte. Komparativ analysstrategi har även använts för att visa på ett vidgat perspektiv inom problemområdet. De teorier som genomsyrar detta arbete är den sociokulturella teorin, kognitivismen och pragmatismen. Resultatet visar att undervisning kring skönlitteratur ofta saknas och bakomliggande orsaker till detta samt beskriver hur tillgång till skönlitteratur främjar läsning. Resultatet belyser såväl fördelar som nackdelar med skönlitteratur i undervisning. Slutsatsen av detta arbete är att skönlitteratur kan ha en positiv påverkan på elevers utveckling av ett flertal förmågor. För att möjliggöra denna utveckling krävs att en mängd faktorer samspelar såsom lärarens unika kompetens, ett tydligt syfte med undervisningen och elevernas aktiva deltagande.

Introduktion: Stroke är en av de stora folksjukdomarna och en av de ledande dödsorsakerna i Sverige. Det är en vanlig orsak till funktionsnedsättning och påverkar personen både fysiskt och psykiskt. Syfte: Litteraturstudiens syfte var att belysa upplevelse av psykisk ohälsa efter en stroke, ur ett patientperspektiv. Metod: Den metod som användes var en litteraturstudie, med deduktiv ansats. Med hjälp av relevanta sökord identifierades elva artiklar i databaserna CINAHL och PubMed, som sedan genomgick en kvalitetsgranskning och slutligen utgjorde resultatet. Resultat: Presenterades i tre kategorier utifrån en modifiering av referensramen enligt följande: Avsaknad av emotionellt välbefinnande, Avsaknad av socialt välbefinnande, Avsaknad av psykisk välbefinnande. Dessa kategorier visade upplevelser av psykisk ohälsa på olika sätt och hur de påverkade patienten. Slutsats: Upplevelser av psykisk ohälsa var vanligt förekommande hos patienterna. Då fokus låg på den fysiska rehabiliteringen hamnade den psykiska dimensionen i skymundan. Det är av stor vikt att sjuksköterskan uppmärksammar och möter dessa upplevelser av psykisk ohälsa i ett tidigt utvecklingsskede, för att undvika vidareutveckling mot mer allvarliga psykiatriska tillstånd.

Background: The Lateral Septal Area (LSA) is involved with autonomic and behavior responses associated to stress. In rats, acute restraint (RS) is an unavoidable stress situation that causes autonomic (body temperature, mean arterial pressure (MAP) and heart rate (HR) increases) and behavioral (increased anxiety-like behavior) changes in rats. The LSA is one of several brain regions that have been involved in stress responses. The aim of the present study was to investigate if the neurotransmission blockade in the LSA would interfere in the autonomic and behavioral changes induced by RS. Methodology/Principal Findings: Male Wistar rats with bilateral cannulae aimed at the LSA, an intra-abdominal datalogger (for recording internal body temperature), and an implanted catheter into the femoral artery (for recording and cardiovascular parameters) were used. They received bilateral microinjections of the non-selective synapse blocker cobalt chloride (CoCl(2), 1 mM/ 100 nL) or vehicle 10 min before RS session. The tail temperature was measured by an infrared thermal imager during the session. Twenty-four h after the RS session the rats were tested in the elevated plus maze (EPM). Conclusions/Significance: Inhibition of LSA neurotransmission reduced the MAP and HR increases observed during RS. However, no changes were observed in the decrease in skin temperature and increase in internal body temperature observed during this period. Also, LSA inhibition did not change the anxiogenic effect induced by RS observed 24 h later in the EPM. The present results suggest that LSA neurotransmission is involved in the cardiovascular but not the temperature and behavioral changes induced by restraint stress.

The lateral septal area (LSA) is a part of the limbic system and is involved in cardiovascular modulation. We previously reported that microinjection of noradrenaline (NA) into the LSA of unanesthetized rats caused pressor responses that are mediated by acute vasopressin release. Magnocellular neurons of the paraventricular (PVN) and supraoptic (SON) of the hypothalamus synthesize vasopressin. In the present work, we studied which of these nuclei is involved in the pressor pathway activated by unilateral NA injection into the LSA as well as the local neurotransmitter involved. Chemical ablation of the SON by unilateral injection of the nonspecific synapses blocker cobalt chloride (1 mM/100 nl) did not affect the pressor response evoked by NA (21 nmol/200 nl) microinjection into the LSA. However, the response to NA was blocked when cobalt chloride (1 mM/100 nl) was microinjected into the PVN, indicating that this hypothalamic nucleus is responsible for the mediation of the pressor response. There is evidence in the literature pointing to glutamate as a putative neurotransmitter activating magnocellular neurons. Pretreatment of the PVN with the selective non-N-methyl-D-asparate (NMDA) antagonist NBQX (2 nmol/100 nl) blocked the pressor response to NA microinjected into the LSA, whereas pretreatment with the selective NMDA antagonist LY235959 (2 nmol/100 nl) did not affect the response to NA. Our results implicate the PVN as the final structure in the pressor pathway activated by the microinjection of NA into the LSA. They also indicate that local glutamatergic synapses and non-NMDA glutamatergic receptors mediate the response in the PVN. (c) 2008 Wiley-Liss, Inc.

Considering the evidence that the lateral septal area (LSA) modulates defensive responses, the aim of the present study is to verify if this structure is also involved in contextual fear conditioning responses. Neurotransmission in the LSA was reversibly inhibited by bilateral microinjections of cobalt chloride (CoCl(2), 1 mM) 10 min before or after conditioning or 10 min before re-exposure to the aversively conditioned chamber. Only those animals that received CoCl(2) before re-exposure showed a decrease in both cardiovascular and behavioral conditioned responses. These results suggest that the LSA participates in the expression, but not acquisition or consolidation, of contextual fear conditioning.
