De första på plats: En fallstudie av entreprenörers resonerande vid etablering på en ung marknad
One of the areas in which current theory on entrepreneurship is ambiguous is in the explanation of how entrepreneurs act when entering a new market. One author that has attempted to contribute in this area is Saras D. Sarasvathy who has tried to explain the entrepreneurs reasoning through the theory of causation and effectuation. The former refers to a reasoning that takes the effect of an entrepreneurial action as given, while the latter looks upon the effects as uncertain, while only the means are given. With a foundation in this theory, Sarasvathy claims that when entrepreneurs enters a new market the level of environmental uncertainty is so high that reasoning based on causal relationships is rendered useless.
Matematik : som eleven ser det Elevers uppfattningar om matematik och matematikundervisning
Studiens syftar till att undersöka elevers uppfattningar om matematik och matematikundervisning. Arbetet består av en litteraturgenomgång och en empirisk del där intervjuer med åtta elever ingår.Både den teoretiskaoch den empiriska delen behandlar tre områden. Dessa områden är: - Varför har vi matematik i skolan? - Vad är matematik?- Hur bedrivs matematikundervisning? Den teoretiska studien beskriver frågeställningarna utifrån hur forskare, författare och lärare ser på det. Inom denna del inryms även en beskrivning om hur undervisning skulle kunna se ut i praktiken.
Omkrets och area : En studie om åk 5-elevers kunskaper och svårigheter
Syftet med denna studie är att studera elevers svårigheter i hanterandet av matematikuppgifter gällande omkrets och area samt att undersöka hur elevers kunskaper motsvarar kursplanens uppnående- och strävansmål. Kvalitativt inriktade intervjuer har använts som undersökningsmetod, då studiens huvudsakliga syfte har varit att på djupet undersöka och ge exempel på elevers förståelse. Elevsvaren har analyserats utifrån hur representationsformer, begreppsuttryck och innehåll används gällande omkrets, area och kursplanens mål. Eleverna visar svårigheter gällande omkrets- och areamätning och areakonservering, vilket utgör uppnåendemål inom målet att kunna undersöka matematiska problem och uttrycka sig muntligt med hjälp av grundläggande matematiska begrepp. Elevernas förståelse ökar när de får visa och förklara sin förståelse muntligt och med hjälp av bilder..
Lex Sarah : Vad händer sen?
This paper aims to find out what lex Sarah is and how the process looks like when it comes to the investigation, from reporting to registration to the IVO, the inspection of health and social care. Who investigates, the objective of the lex Sarah and how many cases of reports that comes to registration from the year between 2010-2014. Which legal consequences it can be for an employee who has been notified is investigated also. Previous research only deals with freedom of speech, criticism and the complaint goes to the asset, and because of that, this paper focuses on individual cases where employees ' perception of a lex Sarah-registration gives a psychosocial approach. The paper is limited to a municipality where statistics are retrieved and a comparison at a national level is performed.
Fungiciders påverkan på kvävehalten i höstvete : hur påverkar användandet av fungicider utnyttjandet och inlagringen av kväve i höstvete?
A common perception is that fungicide treatments increases yield, but that the nitrogen of the particular grain is diluted so that the overall removal of grain nitrogen from the field remains unchanged. The aim of this paper is to demonstrate that a healthy crop reduces the risk of nutrient loss from agricultural land. The results from genotype and plant protection trials often show constant nitrogen content in the grain, although the yield has been increased. Results from such experiments are therefore processed in order to confirm this and show that it is no statistically significant difference between the protein content (and also nitrogen content) in crops which have undergone fungicide treatment compared to crops which remained untreated. The trials processed have been carried out in the southernmost part of Sweden and are distinguished to concern winter wheat production.The explanation to the results is that a healthy crop is able to maintain the biological functions of the plant in a more efficient way than a crop damaged by a fungal infection.
Bedömer lärare det väsentliga?: Vad är väsentligt i matematikundervisningen och vad är det lärare egentligen bedömer?
Syftet med vår studie är att undersöka vad lärare bedömer och vad de upplever vara väsentligt att elever lär sig i matematik. Vi har utgått från aktuell litteratur som vi bedömt som relevant för vårt arbete. Vi har gjort kvalitativa intervjuer med åtta lärare i den kommunala skolan som arbetar i olika samhällen. Intervjusvaren har vi kategoriserat för att resultatet ska bli mer lättöverskådligt. Vi har analyserat svaren och kommit fram till att lärarna är mycket läromedelsbundna.
Motivationsfaktorer : - Vad påverkar motivationsnivån hos telefonförsäljare?
Through an examination on a Telemarketing company this paper aim to investigate which relations there is between the level of motivation and performance and how these are related to the factors that are included in Herzbergs two-factor-theory.In this essay we have been using a questionnaire and interview. We have also been able to collect statistics on employees from the Telemarketing company we examine. On the basis of these data we have analyzed which relations there is.The examination shows on relations who mean that the factors Performance and Acknowledgement are the ones that affect the motivation the most, and therefore the level of Performance. The rest of the Motivation factors don?t show any clear relations.
Simulering av vindkraftverk och närliggande elnät vid Risholmen i Göteborg i SimPowerSystems
With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Kundnöjdhet i revision: En jämförelse mellan företag som reviderats av Big Four och företag som reviderats av någon annan revisionsbyrå
The need for auditing originates from the agency problem that arises due to the separation of ownership and control in companies. The purpose of the audit is to increase credibility of the financial statements that management uses to communicate with owners and other stakeholders. In order for the audit to fulfill its purpose a certain level of quality needs to be obtained. The auditor can also be seen as a provider of a commercial service in which service quality is important. Audit quality can thus be separated into technical quality, which is defined as the probability that the auditor both discovers and reports a breach in the client?s accounting system, and service quality, which relates to the provision of services in general.
Likvärdig utbildning för alla barn? En studie om boendesegregation och diskriminering i Sveriges grundskolesystem
The major focus in this study is structural inequalities in primary school in Sweden. UNESCO points out that in many developing countries, up to 40% of the children perform at or below the lowest proficiency level in language and mathematics. Sweden has been criticized by the UN about the large differences in educational achievements between different regions. Based on an official study Sweden considers that those differences are related to ethnically segregate residential areas. My research question is whether the Swedish government takes adequate consideration of the impact that socioeconomically aspects have on educational achievement.

Language is an important indicator of the interdisciplinarity of a certain subject. Therefore this study evaluates the use of central geographical words and concepts, by teachers and students, in seven communal, non-optional subjects in a Swedish upper secondary school. This study provides results after observations of seven subjects on seven occasions, at one upper secondary school. This study shows that by a method of observation, central geographical concepts were used by teachers and students at various extents. Furthermore, the observations provide results of the concept use by over 100 students and 12 teachers.
Effekten av discoverytjänster på bibliotekens e-resurser? ? En undersökning om Summons effekt på Chalmers bibliotek.
The purpose of this essay is to examine what happens with library e-resources after implementing the discovery tool Summon. Summon provides a Google-like experience and uses multiple facet options when users need to narrow their discovery. Observations of change in the libraries e-resources with regards to database searches, click-throughs in linkresolvers and full text downloads are examined through looking at earlier reports and statistics from libraries in America and England. This provides a way to compare with Chalmers University of Technology?s Library.
