The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.

Syftet med studien var att undersöka självförtroende och kroppsbild hos datorspelare, styrketränare och en kontrollgrupp. En webbenkät med manliga medlemmar på dator- och idrottsrelaterade internetforum genomfördes. Kontrollgruppen var medlemmar på dessa forum som varken styrketränade eller spelade datorspel. Skalorna Social physique anxiety scale, Rosenberg self-esteem scale och Drive for muscularity scale administrerades. Resultatet visar att grupperna inte var signifikant skilda åt gällande social fysisk ångest eller självförtroende.

Östby waterworks in the community of Kramfors has since 2003 had problems of fast clogging of the slow sand filters. As the clogging appears more often, they must be cleaned more frequently which has made the drinking water preparation difficult. Wintertime it has sometimes been impossible to clean the filters which has led to their closing and this has influenced the water quality negatively.The waterworks is a surface waterworks which takes its raw water from the lake Sjöbysjön. The water is flocculated and filtered in a contact filter with the flocculent EKOFLOCK 91. Thereafter it is alkalinized before it reaches the outdoors placed slow sand filters.

The main purpose of this study was to inquire into personality and the state anxiety in relation to career decidedness scale among students in upper secondary school. The participants were 124 students in three grades and respectively non vocationally oriented classes. The participants were asked to grade themselves on a scale in relation to the statements regarding, state of decidedness for career choice, personality (NEO FFI, Costa & McCrae, 1985. Sweden, Gerontologic Center) and anxiety (AnTI, Wells, 1994). The results showed no significant relationship between personality and state of anxiety that could be connected to the decidedness for career choice.

In the fall 2011 a new grading scale will be implemented in the Swedish school. A government bill suggests a change of the scale from a three- to a six-point scale. The students will also be graded from the sixth class instead of today?s eighth. From the first year of the compulsory school the pupil will get a written judgment.

Forskning har indikerat att individer med högt välbefinnande är bättre på att bemöta stress. Syftet med föreliggande studie var att undersöka vilka faktorer som skiljer individer med högt välbefinnande från dem med lågt välbefinnande, samt om deltagarna med högt välbefinnande har en bättre förmåga att hantera stress samt balansera krav och kontroll. 184 personer, varav de flesta kvinnor, har fått fylla i Ryff Psychological Well-being scale, Perceived Stress Scale och Job Content Questionnaire för att mäta välbefinnande, upplevd stressnivå och balansen mellan krav och kontroll. Två grupper skapades, en med lågt (n=20) och en med högt välbefinnande (n=20). Det framkom att gruppen med lågt välbefinnande ansåg sig ha signifikant lägre kontroll än gruppen med högt välbefinnande (p=.015).

The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

Stress är idag ett område som är allt mer omdiskuterat och anses ha inverkan på den psykiska hälsan. Många studerande på universitetsnivå upplever någon gång under utbildningen stress, och detta kan bland annat förklaras utifrån tidspress, ny stad samt ekonomi. Syftet med denna studie var att ta reda på huruvida stress hos studenter kan förklaras utifrån self-efficacy och fysisk aktivitet, samt om det finns någon skillnad i upplevd stress mellan manliga och kvinnliga studenter. Det var 76 av 92 tillfrågade studenter som svarade på hela enkäten (39 män och 37 kvinnor) som innehöll två standardiserade tester, General Self-Efficacy Scale respektive perceived stress scale. Resultatet visade ett signifikant samband mellan variablerna stress samt self-efficacy.

Syftet med studien var att ta reda på om det går att predicera medarbetares livstillfredsställelse, psykosociala välmående och upplevd relation till närmaste chef utifrån chefers emotionsperception och emotionsreglering. Detta gjordes genom att 38 chefer utförde ett datorbaserat emotionsperceptionstest samt besvarade Emotional Regulation Questionaire. Deras närmaste medarbetare bestående av totalt 213 stycken fick sedan besvara en enkät bestående av delar från Satisfaction With Life Scale, SF-1 och QPS Nordic. Studiens huvudresultat visade att generaliserat kan resultatet från emotionsperceptionstestet och det självrapporterade användandet av omvärdering av känslor hos chefer förklarar 28 % av skattningarna på Satisfaction With Life Scale hos medarbetarna. Resultaten diskuteras i termer av att chefer skapar en positiv atmosfär på arbetsplatsen, identifierar sociala problem och löser konflikter effektivare när de är skickliga på emotionsperception och omvärderar sina känslor..

This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.

Theory of mind involves the ability to take another person?s perspective in thought, emotions and intentions.  There is today a lack of instruments to assess children?s development of Theory of Mind (ToM) in Swedish. ToM is considered by many scientists to be the basis for development of pragmatic competence. The relationship between these two abilities is complex and not fully resolved. Both abilities are important components for the development of social skills.    The purpose of this study was to compare 4 and 5-year olds ToM-ability measured with a Swedish version of Wellman and Liu?s ToM-scale, Sally Anne and Social Emotional Test with estimated pragmatic competence measured with the Children?s Communication Checklist (CCC).
