Uppsatsens utgångspunkt är att perspektivet utgör en psykosocial länk mellan individ och omvärld. Med grund i Henry Montgomerys perspektivmodell, som bland annat framhåller hur fakta och värderingar är intimt förbundna i social perception, förs ett resonemang kring perspektivets socialpsykologiska förankring i mellanmänskliga sammanhang. Modellens element subjekt, objekt och mental position diskuteras systematiskt utifrån George Herbert Meads perspektivteoretiska ansats samt Alan Page Fiskes socialitetsteori. Syftet är främst att visa på perspektivets deskriptiva och evaluativa konstitution, dess sociala grund och kontextberoende. Tanken är att Meads resonemang fungerar som en formell teoretisk grund för subjektet och dennes kommunikativt grundade intersubjektivitet, genom perspektivtagandet via symbolbruk och den generaliserade andra, emedan Fiskes ansats tar fasta på en bestämd social differentiering genom socialitetsformer vilket i sig utgör fundamentet för värderingars sociala förankring samt människors socialitet i en mer substantiell mening.

Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environMental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Students who do not achieve the different credentials that Elementary schools demand because of their mental disability, have the alternative to go to special school. Special school has a reduced course of studies, which correspond  to the students' different conditions and qualifications. The students who go to special school have done assessments to establish their need of extra help and support in their education. This paper want to show how the schooling of the children can be experienced from a parental point of view. Parents with children with special needs constantly have to make different choices to promote their children's development. In this study the parents of disabled children have been interviewed about their children's participation and intergration in ordinary schools and later in special schools.

Human Resource Management (HRM) handlar om att leda mänskliga resurser. Det blir det allt vanligare att personalansvaret delegeras till linjecheferna i organisationen eftersom de arbetar närmast de anställda. Syftet med denna studie var att med kvalitativ metod undersöka på vilket sätt chefers arbetssituation skiljer sig åt mellan de som har, respektive inte har, en HR-avdelning att tillgå. Studien baserades på nio enskilda intervjuer vilka tolkades enligt induktiv tematisk analysmetod. Resultatet visade att personalarbetet var mer integrerat i det dagliga chefsarbetet på företag som hade HR-avdelning, och dessa chefer kände sig inte stressade av personalansvaret i sig.

Studiens syfte var att undersöka vilka former av psykisk ohälsa som skolkuratorer mötte samt hur de arbetade med detta. Vi har därför utfört en kvalitativ studie och intervjuat sex skolkuratorer som arbetar med högstadieelever. Resultatet visade att psykisk ohälsa var ett mångtydigt begrepp, men att de mest centrala formerna av psykisk ohälsa i skolan var stress, prestationsångest och självskadebeteende. Skolkuratorernas arbetsuppgifter upplevdes som diffusa, men de tre mest framträdande arbetsuppgifterna i samband med psykisk ohälsa var kartläggning, enskilda samtal samt att remittera elever vidare till andra aktörer. Skolkuratorerna fokuserade främst på akuta insatser vilket resulterade i att det förebyggande arbetet att motverka psykisk ohälsa blev eftersatt.

Background: During the last decades patient satisfaction has become an important measurement of quality in psychiatric care. However the patients are seldom asked to evaluate the treatments.Objectives: The aim is to determine which factors the outpatients regard as beneficial in their psychiatric treatment. The purpose is explorative. During the study another purpose developed; to present research on the importance of the relationship between the caretaker and the caregiver for the outcome.Method: 30 persons were interviewed about what they found helpful in psychiatric treatment. The interviews were open using Grounded Theory as methodological input.Result: The most prominent topic was the quality of the relationship between the caregiver and the caretaker.

Bakgrund: Den psykiska ohälsan ökar hos barn och unga. De ökade psykiska besvären hos elever kan knytas till den individualisering som är en del av den moderna utvecklingen. Att så tidigt som möjligt upptäcka och behandla psykisk ohälsa är angeläget. Skolsköterskan är central för skolhälsovården då hon är tillgänglig i elevernas vardagsmiljö.Syfte. Att belysa skolsköterskans upplevelse av psykisk ohälsa hos elever.Metod: Som metod valdes semistrukturerad intervju.

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

Syftet med denna studie är att undersöka elevers tankar, känslor och upplevelser av studier inom det individuella gymnasieprogrammet. Enligt tidigare forskning och enligt teorierna framgår det att elever som går det individuella programmet har negativa tankemönster, upplever psykisk ohälsa och depressiva symtom. I undersökningen har både kvantitativa och kvalitativa data analyserats. En enkätundersökning har skickats ut hos eleverna och två intervjuer har gjorts, en intervju med en lärare och en med en kurator. Resultatet visar höga procent av negativa tankemönster, depression och psykisk ohälsa hos eleverna.

During the autumn 2009, a 15 hp degree project was accomplished. The objective of the study was to describe different equipment alternatives, suitable for fresh market apple harvest. A field study was conducted during the harvest period to evaluate the efficiency (kg / person/ hour), using the different equipment. Four different systems are described in the study; Pick-ing-bag, Picking-train, Pluk-O-Trak and the Conveyor Harvester. The information about the systems is based on interviews with growers together with previous studies.

Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.

This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.

The purpose of this examination is to get a view of the attitude towards internet-use within after school centers. By comparing the views of pupils with the teacher?s point of view, one can notice differences that may be due to a lack of knowledge or communication. The questions are: What view does the principal, the staff, and the pupils have on internet-use in after school centers? Does their view differ? If so, how? To be able to respond to these questions, the pupils and the staff have been handed surveys and the principal has been interviewed.
