Avskaffandet av revisionsplikten : effekten på bankers utlåningsprocess till småföretagare
På grund av avskaffandet av revisionsplikten som började gälla den 1 november år2010 kan idag små företag välja bort sin revision. 250 000 av Sveriges företag är enligtlag berättigade att själva välja vilka revisorstjänster de är i behov av samt i vilkenomfattning.För att banker ska bevilja lån till små företag krävs det en säkerhet som speglarföretagens förmåga att betala kommande räntor och amorteringar. Säkerheten ligger igranskade revisioner och när de blir frivilliga kan tillförlitligheten minska.Metoden som använts är kvalitativ och har utformats via personliga intervjuer medbanker och revisionsbyråer.Syftet med studien är att beskriva effekten av avskaffandet av revisionsplikten påbankers utlåningsprocess till mindre företag.Frågeställning:?Är bankerna villiga att bevilja utlåning av krediter till små företag utan revisor??Finns det någon information som kan ersätta reviderade räkenskaper??Har långa relationer någon påverkan på bankers kreditbedömningsprocess??Hur ser revisionsbyråerna på avskaffandet av revisionsplikten?Slutsatser:Majoriteten av bankerna är villiga att bevilja kredit till företag utan revision. Dock krävsfler beslutskriterier för att bedöma ett företags återbetalningsförmåga.
Utbildade invandrare och kampen för ett jobb : En kvalitativ studie om hur några invandrare med akademisk utbildning beskriver sin situation på den svenska arbetsmarknaden
According to several studies immigrants today in general face more difficulties to enter the labor market than before. This also applies to educated immigrants who are the main focus of this thesis.Studies have shown that educated migrants have more difficulties of obtaining an adequate job than ethnic Swedes. Thousands of educated immigrants are forced to work in low skilled occupations to cope with their everyday lives. The reasons behind their lack of success on the Swedish labor market have been blamed on different kinds of obstacles. This study wants to examine at least some of the obstacles that educated immigrants face on the labor market through some informants own personal reflections and experiences. The study is based on an inside perspective in which the different personal experiences and reflections of the various informants is of great importance. The study is focused on how five educated immigrants describe their situation on the Swedish labor market. The aim is to investigate the informants 'understanding of the difficulties they have to get a job that matches their skills. It also aims to discuss the structural barriers that respondents relate to when they describe their situation. The results of the interviews with the informants have been analyzed with the help of central concepts gained from the two sociologists, Erving Goffman and Pierre Bourdieu.
Dynamisk modellering av vindkraft : En studie av dynamiska beteenden hos inbyggda vindkraftmodeller i PSS/E
Detta examensarbete behandlar dynamiska vindkraftmodeller i simuleringsprogrammet Power System Simulator for Engineering (PSS/E) som används av Svenska Kraftnät vid analyser av det svenska stamnätet. Syftet med examensarbetet har varit att förenkla Svenska Kraftnäts hantering av vindkraftmodeller vid olika analyser av nya vindkraftparker som ska kopplas in på stamnätet. Detta gjordes genom att undersöka om dagens modellering av vindkraft, bestående av negativa laster och tillverkarspecifika vindkraftmodeller, kan ersättas av en generisk representation med de modeller som finns inbyggda i PSS/E. Rapporten ger en teoretisk beskrivning av vilka tekniker som används i vindkraften idag och hur de vindkraftmodeller som används i PSS/E är utformade. För de inbyggda modellerna i PSS/E har både vindkraftverk med dubbelmatad asynkrongenerator (DFIG) och vindkraftverk med fulleffektomriktare studerats. Resultaten visar att en generisk representation av vindkraftverk med DFIG kan göras med den inbyggda modellen i PSS/E med de parametervärden som finns rekommenderade i denna rapport. I den inbyggda modellen för fulleffektomriktare finns dock begränsningar som gör det olämpligt att använda en generisk representation för denna vindkraftstyp. Övriga slutsatser som dragits är att de inbyggda vindkraftmodellerna i PSS/E inte är tillräckligt flexibla för att fullständigt kunna representera ett dynamiskt beteende från en godtycklig tillverkare i händelse av ett systemfel..
Är vi artiga mot virtuella agenter?
The CASA-paradigm, Computers Are Social Actors, was introduced in the book "TheMedia Equation" by Reeves and Nass. One of their experiments concluded that we tend to be polite to computers in the same way as we are to people. In this study I have replicated Reeves and Nass experiment but instead of a text-based interface I have used a virtual agentin order to find out if we are polite to the agents, or still to the computer. Two experimental setups was conducted. The two setups had a common first part that was carried out on onecomputer with one agent.
Solenergi : en lönsam investering för ett lantbruk?
A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.
Att leda - N?r juridiska krav kolliderar med personliga v?rderingar
This study aims to analyze the effects of the proposal regarding mandatory reporting for undocumented individuals within the Swedish public sector and how this potentially affects leaders in their efforts to motivate their employees to comply with this requirement, which is considered ethically charged. The primary focus is to understand how these leaders can motivate their employees considering legal requirements that are both legally binding and ethically sensitive.
By interviewing leaders from various sectors within the public domain in multiple Swedish municipalities, this case study seeks to highlight the challenges arising from the amalgamation of legal mandates and ethical dilemmas. Its goal is to provide insights that can support these leaders in their complex decision-making regarding such issues. The study addresses theoretical aspects such as change management and critical organizational theory.
The study's findings indicate that political decisions play a pivotal role in the processes of change within public operations. Resistance to change varies and takes various forms.
Miljö- och Personalreglering i Förvaltningsberättelsen : - En studie av Svenska Börsnoterade Företag
The environmental work of companies has become an incredibly important factor in achieving reduced levels of environmental pollution. For companies the work on environmental issues began in the 1980s. During this time companies also began to show interest for the personnel, an interest that was shown in the form of attempts to disclose personnel information in economics. Earlier this information was separated from the financial information, despite the fact that the revenues are created by the employees.The purpose of this paper is to examine how well companies with a notification or a permit today account for environmental- and personnel information in their director?s report.
