Nya inslag i bostadspolitiken konsekvenser för Helsingborg

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Ta rygg på insiders? : En studie om möjligheten till abnormal avkastning genom replikering av insiders köp & säljtransaktioner

Ända sedan handeln med finansiella instrument utvecklades under början av 1900-talet har problematiken kring insiderhandel existerat. Denna problematik bottnar i att personer med ett informationsövertag, dvs. insiders kan enligt vissa tidigare utförda studier generera abnormala avkastningar vid exempelvis aktiehandel. Oenigheten på detta forskningsområde är relativt stort. Det skulle därför vara intressant att titta på möjligheterna till abnormal avkastning genom att replikera insiders köp- och sälj transaktioner på den svenska aktiemarknaden.Denna studies frågeställning formuleras således; Kan utomstående investerare generera abnormal avkastning genom att replikera insiders köp- respektive sälj transaktioner på Stockholmsbörsens Small Cap lista?För att svara på denna frågeställning genomfördes en kvantitativ studie innehållande 60 stycken bolag noterade på Stockholmsbörsens Small Cap lista.

Systematisering av information på företag en fallstudie

The purpose of this paper is to investigate how a small company manages its information, primarily the organization of digital documents. The two dominating themes are classification and information politics, the former in the context of a corporate environment and the latter to help us to describe the situation at the company. The method used has involved observation of the company's current computer network structure and also interviews with six employees at different levels in various departments at the company. The result of our investigation has been the realization that, although logical structure is important when organizing documents in a digital environment, it is also necessary to have rules regarding its implementation..

Utveckling Ulricehamn- om stora förändringar i en liten stad :

The purpose of this thesis is to inquire how a small town can be affected by some planned changes in the physical structure of the town, and how its inhabitants can benefit from those major changes. The town in question is Ulricehamn, and of the four projects considered, two concerns infrastructure. A new railway and a new locality for the major road, today passing through Ulricehamn. The other two projects are run by the local authorities, that is the planning of a modern town park by the lake, and a new public building for cultural purposes. There are no guarantees that any of the four projects will ever be realized, but in the process with this work, they have been considered as already a fact.

Sourcingmöjligheter ? en jämförelse mellan den portugisiska och kinesiska

The lifecycle of fashion products get shorter and shorter. Companies in the fashion business needto make sure that they can offer their customers the right products, in the right quantity at theexact right time. The competition on the fashion market today is tough and if companies aregoing to be successful they need to have access to the most reliable suppliers, and also offer theircustomers products with high quality to attractive prices. It is therefore of highest importance toevaluate and choose the right sourcing strategy. Product category and type of organisation aresome of the factors that will determine which strategy that is most appropriate.

Livsmedelssäkerhet för skolor, förskolor och äldreomsorg i Varbergs kommun; HACCP för tillagnings- och mottagningskök

One of the main objectives of all food production is to produce foods that can safely beconsumed without fear of being sick. Despite this hundreds of people are affected in Sweden offood poisoning almost every day. Most cases are caused by a small group of so-called pathogenicmicroorganisms. The most frequently affected are the small children, the elderly, persons withreduced resistance and pregnant. The reasons behind the food poisoning are often ignorance andlack of food hygiene.

Rörelseaktivitet för små barn : Några förskolepedagogers syn på vikten av att ha planerad rörelseaktivitet i förskolan

Studier har visat att frivilligt barnlösa individer stereotypt har betraktats vara olyckliga och otillfredsställda, något som inte har fått vetenskapligt stöd. Syftet med den här tvärsnittsstudien var att undersöka om det föreligger några skillnader i livskvalitet och livstillfredsställelse mellan frivilligt barnlösa personer och föräldrar i den svenska populationen. Forskningsfrågan undersöktes med en enkät som bestod av självskattningsskalorna QOLI (Quality Of Life Inventory) och SWLS (Satisfaction With Life Scale). 130 deltagare genomförde studien varav 54 är frivilligt barnlösa individer och 76 är föräldrar. Studien visade att det inte finns några signifikanta skillnader mellan grupperna med avseende på livskvalitet och livstillfredsställelse.

Motivation till personlig utveckling

Den, i olika forskningsartiklar, återkommande uppfattningen om att enperson som är autonomt orienterad är mer benägen till att utveckla enmotivation till personlig utveckling ledde till denna undersökning.Syftet med studien var att undersöka hur autonomi påverkar människortill motivation till personlig utveckling. Studien tar sin utgångspunkt iself-determination theory och dess underteori causality orientationstheory, med de tre orienteringarna kontrollerad, impersonell ochautonomi, vilka handlar om orsak till varför en person handlar på ettvisst sätt och effekten därav. De olika orienteringarna mättes med enenkät konstruerad efter general causality orientation scale ochmotivation till personlig utveckling mättes med egenkonstrueradefrågor. Enkäten lades ut på fyra olika sidor på Internet medförhoppning om att nå ett brett deltagande. Studien visade att denkontrollerade orienteringen var den av de tre orienteringarna sompåverkade människor i högst grad till motivation till personligutveckling.

Förändringskommunikation i organisationer : En studie som jämför hur uppfattningar skiljer sig mellan chefer och medarbetare i en förändringsprocess

Title: Change Communication within organizations ? How perceptions differ between managers and employees in an organizational changeAuthor: Emma Ender & Fanny TeschTutor: Anne-Marie MorhedPurpose: The purpose of this thesis was to study and compare different perceptions of change communication between managers and employees within two smaller organizations. We wanted to examine how the communication process within the change was carried out. We also aimed to compare the results with change communication models of Johansson & Heide (2008) and Lewin (1951), and also existing concepts, to see if our result differed from earlier research. Our key questions to answer were: How do managers communicate a change to the employees in two smaller companies? How do the managers think that the employees perceive the information about the change? How do the employees perceive the information about the change? How does change models from previous research correspond to, or differ from the change process?Method/Material: The material used in this thesis consists of a total of twelve interviews with both managers and employees at two small companies.Main results: The main results shows that communicating a change is complex, and that it is difficult to create models and theories for the phenomenon, as each change is unique.
