Problembakgrund/Problemdiskussion: Mitt under brinnande finanskris 2008 tvingades den välkända storbanken Lehman Brothers ansöka om konkurs. Bankens konkurs i kombination andra finansiella instituts var startskottet på en intensiv debatt beträffande flertalet företeelser på den finansiella marknaden. En av dessa företeelser var blankning. Kritiker menar att blankning bidrog till att destabilisera en redan skakad marknad och generera omotiverat stora prisras på aktiemarknaden. Förespråkarna menar och andra sidan att det inte är blankning som formar marknaden utan att det endast är en strategi baserad på brister i marknaden. Oavsett vilken sida som står närmast sanningen ledde debatten till att EU instiftade ett nytt regelverk, som till viss del begränsar blankning och ökar dess transparens. Den första november 2012 började detta regelverk tillämpas i Sverige, och innebär kortfattat att alla större blankningsorders ska offentliggöras av Finansinspektionen (FI). Den stora frågan är därmed vilket bidrag blankning har på den svenska aktiemarknaden efter att detta regelverk börjat tillämpas. I ett försök att undersöka detta kommer den publicerade informationen av FI att bearbetas i denna studie. Problemformulering/Syfte: Utifrån följande frågeställning kommer studien att fokusera på huruvida blankning påverkar volatiliteten på den svenska aktiemarknaden: Påverkar blankning aktieprisvolatiliteten?Syftet är därmed att klargöra om FIs offentliggörande av blankningsorders har någon effekt på volatiliteten på den svenska aktiemarknaden. Teoretisk referensram: Studiens resultat har analyserats och diskuterats utifrån följande teorier: den Effektiva marknadshypotesen, den Adaptiva marknadshypotesen, Informationsasymmetri & Signalteori, Prismanipulation och Beteendebaserad finansiell ekonomi. I detta avsnitt har även tidigare studier inom ämnesområdet behandlats. Metod: För att undersöka om det föreligger ett samband mellan blankning och volatilitet på den svenska aktiemarknaden har en kvantitativ studie genomförts. Studien är baserad på blankningsorders för 53 bolag, som FI:s offentligt publicerat mellan den första november 2012 till den sista januari 2014. Genom användandet av multipla regressioner och ett antal förklaringsvariabler har det statistiskt undersökts om det förelegat något samband mellan bolagens dagliga varians och tillfällen när blankning förekommit. Empiri/Analys/Slutsats: Utifrån de statistiska tester som genomförts i det empiriska kapitlet går det inte att dra några slutsatser beträffande om publicerade blankningsorders har någon effekt på volatiliteten. Därmed finns det inget statistiskt stöd för att blankning påverkar volatiliteten på den svenska aktiemarknaden.

The purpose of this study was to determine the value of emphasizing the teaching of the short story as a means of stimulating young people in reading better literature.

These pieces were written as an exercise in examining how people, with all their idiosyncracies and differences in perception, can experience a single event in massively different ways. The headline for this story is simple. A young man on break from college comes out as gay to his best friend, and when his erotic feelings are unrequited their summer together falls apart. That is the story, but where is the truth? As I see it, the truth as we think of it is unobtainable. There is no one, perfect version of events that satisfactorily explains the hugely different reactions among the four characters that inhabit these stories. There are as many versions of the truth as there are people who experience it. Would you care to read and add another?

The aesthetics of contemporary short fiction have been shaped by its ability to engage with time as a boundless process of becoming. Historically and philosophically, the emergence of the short story as a specific genre may be related to modernist concepts of time and subjectivity. 'Real' time, as it is experienced by the subject, is a flux, in which past and present co-mingle. In Bergsonian terms, an unquantifiable 'duration' 1S contrasted with Newtonian concepts of absolute time as a succession of discrete units. As Hanson has argued, narrative in the short story 1S structured by a seemingly random association of 1mages rather than linear causality. I contextualize the short story genre, historically and culturally, examining texts by George Egerton and Katherine Mansfield before moving on to the main focus of my thesis, which is texts by Alice Munro and Grace Paley. These also present a dynamic reality, within time as a continuum. However, while utilizing modernist techniques, they also subvert them, problematizing concepts of transcendence. The blurring of the boundaries between autobiographical discourse, orality and fiction is used to destabilize notions of a unified subjectivity and of fixed truth. My analysis applies Bakhtinian theories on language and subject formation to investigate this presentation of time as endless self-renewal. I also draw on Genette's narrative theory and introduce Kristevan theory to investigate the speaking subject from a psychoanalytical viewpoint, with particular reference to the gendered subject. The Bakhtinian concept of the chronotope enables the theorization of the space-time nexus as the foundation of generic specificity; I offer a generic chronotope for the short story, which is grounded in the present moment. An examination of the fiction-making process, through a discussion of my own short stories, concludes this discussion of the short story as a form of contact with undefinable reality.

This is a collection of short stories.

Previous studies of how working memory (WM) capacity affects lexical ambiguity resolution have been inconclusive about the choice between inhibition and activation comprehension strategies. In contrast, an adaptive inhibition hypothesis suggests that this choice depends on the availability of WM resources. We used a cross-modal semantic priming paradigm. Participants listened to sentences biasing the subordinate meanings of homonyms, presented at a fast or slow speech rate. We measured lexical decision response latencies to target words that were related to either the subordinate or dominant meaning of homonyms. A WM test was used to evaluate participants' WM capacity. At a fast rate, both high and low WM participants activated dominant (or irrelevant) meanings of the subordinate-biased homonyms. At a regular rate, participants with low WM capacity activated dominant meanings; however, participant with high WM inhibited them. Thus, people with high WM activate and inhibit alternative meanings more flexibly than people with low WM.

Two dual task experiments were conducted to determine the function and content of working memory in concept attainment. Levine's (1966) concept attainment paradigm was used as the primary task. The secondary task in each experiment made selective demands on one of two working memory components, either the phonological loop or the central executive. The effect of the secondary tasks on the performance on the Levine task was measured by frequency of hypothesis use, consistency of hypotheses with previous feedback, and strategies employed to manage feedback. These measures revealed that the two working memory components play different roles in concept attainment. The phonological loop is responsible for maintaining hypotheses, while the central executive carries out mental operations that enable the use of hypotheses that are logically consistent with the given feedback. These findings make it possible to provide a detailed account of the role of working memory in concept attainment and yield new insights into the concept attainment process.
