Global uppvärmning : gymnasieelevers oro och kunskap

Global warming is generally recognized as one of the major environmental challenges we have to face in the near future. The students in school today are the ones that will have to deal with the consequences of it tomorrow. That is why education about it is so important. Previous research shows that students believe that environmental issues in general are important problems to be solved. I this study I tested students in grade twelve, in four different schools in order to find out what their level of knowledge about global warming is, how worried they are about it and if there are any correlation between their knowledge and their level of worry.

Elektronisk motorstyrning för ottomotorer

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

Kundorderstyrd tillverkning ? Påverkande faktorer, förutsättningar och problem : En övergripande studie om hur små och medelstora företag flyttar kundorderpunkten och går mot mer kundanpassning.

This study presents a holistic view of which factors small and medium-sized enterprises (SMEs) have to consider, in moving their customer order decoupling point (CODP) further from the customer, thereby becoming more customized. The study also investigate whether SMEs and larger enterprises differ in the strategic questions relating to what influences an enterprise to become more customized, which prerequisites are required and which problems enterprises should anticipate and prepare for. These questions are important, given that strategic change is challenging, and can take considerable time to accomplish; it therefore needs to be based on the right decisions. This study is motivated by the fact that the markets SMEs are selling to tend to become more and more complex and harder to anticipate. Increased globalisation and use of IT and ICT have lead to greater uncertainty in customer demand.

Den etniska identitetens påverkan på partnerval och attraktion: Leker lika barn bäst?

SammanfattningStudien utredde orsaken till partnerval inom den egna etniska gruppen. Judiska universitetsstuderande (n=42) jämfördes med icke-judiska svenska universitetsstuderande (n=42) och deltagarna jämfördes på variablerna ingruppsidentitet, likhet, stöd från socialt nätverk, partnerval och kollektivism. Dessutom attraktivitetsskattades personer med och utan davidsstjärna. Bäst prediktor för svenskarnas preferens för partnerval inom gruppen var stöd från socialt nätverk medan likhet var bäst prediktor för judarnas ingruppspreferens. Ingruppsidentitet predicerade partnerval inom gruppen för judarna, men inte för svenskarna.

Användning av Self Organizing Maps som en metod att skapa semantiska representationer ur text

Denna studie är ett kognitionsvetenskapligt examensarbete som syftar på att skapa en modell som skapar semantiska representationer utifrån ett mer biologiskt plausibelt tillvägagångssätt jämfört med traditionella metoder. Denna modell kan ses som ett första steg i utredningen av ansatsen som följer. Studien utreder antagandet om Self Organizing Maps kan användas för att skapa semantiska representationer ur stora mängder text utifrån ett distribuerat inspirerat tillvägagångssätt. Resultatet visar på ett potentiellt fungerande system, men som behöver utredas vidare i framtida studier för verifiering av högre grad..

Kan en standard för miljökommunikation förbättra miljöprestanda? : Ett examensarbete i samarbete med NQA Nordic AB

Mankind has always been communicating, it is almost impossible to not communicate. The communication tree has grown a new branch, the environmental communication branch, and an ISO standard, the ISO 14 063 Environmental communication- guidelines and examples was issued October 2006. The purpose of this thesis is commissioned by the managing director of NQA Nordic AB in order to examine and analyse how organisations communicate environmental issues today, and how big the need for ISO 14 063 actually is, and further more if there are needs and wishes to make ISO 14 063 a certifiable standard. The main conclusion is that the there is a need for the standard, but it is difficult to say in which form since the knowledge about the standard is far to low among the organisations examined in this thesis. Clarity and transparency as ISO 14 063 promotes are important ingredients in organisations? environmental work, so sure a standard for environmental communication can help improve environmental performance, for example through opening up for two-way communication and from that on take part of the stakeholders? opinions.This study is based on a literature study and a questionnaire survey where 70 organisations (in this case authorities, corporations and non-governmental organisations) randomly chosen from the seven criteria, which ISO 14 001 defines as the environment: land, water, air, flora, fauna, natural resources and man and his collaboration with those.

Hur science parks och inkubatorer kan stötta kommersialiseringen av idéer sprungna från näringslivet: En studie av Science Park Jönköping samt några företag i regionen

This master thesis has been written in collaboration with Science Park Jönköping and is based on a problem related to corporate innovation. Science Park Jönköping believes that there is an untapped potential in existing industry in the form of ideas that are never commercialized. These theories are also supported in the research in which other authors have perceived that the ideas and inventions which do not belong to the core business risk ending up in drawers. If more of these ideas could be spin-offs or other forms of enterprise instead of staying in the drawers it would lead to growth, both for companies and for the society in large.The purpose of the thesis work is to, based on the case Science Park Jönköping, analyze how science parks and incubators can support the commercialization of ideas that derive from industry, who otherwise had been left lying. The work began with a mapping of the Science Park Jönköping operations and the skills they possess, and then other initiatives that aim to commercialize more ideas from companies were examined.

Resan mot partnering

The purpose of this thesis is to examine how the working method partnering has been welcomed in the Swedish construction company NCC and find possible explanations to this. The theoretical background used to understand and discuss our findings mainly builds on value and network dynamics. The empirical study is of a qualitative nature and builds upon 13 semi-structured interviews and the participation in a two-day start up workshop with 21 representatives from involved parties. The study shows that partnering has been positively accepted at NCC. Possible explanations for this can be found in the contrast the method represents to the traditional way of working within the construction industry.

Entreprenörskap på landsbygden : 6 små livsmedelsförädlande företag i Mälardalen

For a long time, economic activity has decreased and shows a downward trend in the food sector. To break this requires efforts to strengthen corporate position with the ability to meet market challenges. In the small producers is a great potential for them to be able to increase its profitability thanks to its ability to offer added value in the product. But to achieve this requires not only a willingness and creativity out of the ordinary but also factors that lead us into this report, current issues. The issues are related to marketing, brand building and the importance of developing a stable network. The study aims to investigate how small businesses operate in rural areas are experiencing the possibilities of support from various networks and organizations and that, from a business perspective, and also see which areas that they need more support in to achieve a growing business. The work has been followed by an inductive method, when we initially could not say anything about the empirical results.

Projekt Pet Shop

This essay presents a business plan for the idea of a Pet Shop in Stockholm. The initial purpose of the essay was to investigate weather the company would be financially profitable or not. During the process we encountered problems and pitfalls that we felt contributed to the fact that our business idea is yet not realized. Therefore the second purpose of describing the process that an entrepreneur goes through when starting a new business came about. Besides the business plan for Pet Shop we present a selection of the theories that we found relevant for our situation, among others behaviour of entrepreneurial teams, network theory and execution.

Narrativ i visuell media

Denna undersökning omfattar kamerans inverkan på narrativet i visuella medium. Syftet är att få en insikt i hur kunskap om kameratekniker och ?vinklar påverkar hur åskådaren uppfattar vad regissören vill förmedla, och undvika att fokus sätts på element i filmscener som riskerar att förvirra åskådaren. För att undersöka detta problemområde har litteratur om filmhistoria och kamerateknik använts för att sammanfatta kunskap om hur kameran skall användas, för att förmedla relevant information och bygga upp den effekt som regissören strävar efter. Informationen utifrån detta har därefter tjänat som utgångspunkt för att skapa en kort animerad film med rymdtema där kameran eftersträvar att leverera en konkret visuell upplevelse där vinklar används för att understryka vad varje scen vill förmedla.
