Vän eller Vänskaplig : Ett dilemma i rollen som chef
Motivation för ledarskap styrs av värderingar, personlighet och tro på sin förmåga. Forskning har genererat tre motivationskategorier för ledarskap, affektiv-identitet ledarmotivation, icke-kalkylerande ledarmotivation och social-normativ ledarmotivation. Studien undersökte dessa tre motivationskategoriernas inbördes rangordning och skillnader mellan utbildningsinriktning och kön samt samband med generell self-efficacy och personlighetsegenskaper enligt femfaktormodellen. 192 studenter deltog från en mellansvensk högskola, därav 54 män, 90 från socionomprogrammen, 72 från det internationella businessprogrammet och 30 från två ingenjörsprogram. De besvarade en enkät bestående av Chan och Drasgows Motivation to lead scale, Chen, Gully och Edens General self- efficacy scale och Shafers femfaktormodell Big Five Marker. Resultatet visar att det finns skillnader mellan motivationskategorier och utbildningsinriktning.
En jämförelse mellan linjära och traditionella bedömningssystem hos hästar
In Sweden the breeding organization for the Swedish Warmblood horse uses a traditional scoring system when evaluating horses. The horse is scored subjectively in relation to how good each trait is in relation to the breeding objective. Other countries, for example the Netherlands, instead use a linear scoring system. The linear scoring system evaluates the horse on a scale between two, for the breed, biological extremes which makes the evaluation more objective since the judges personal values does not influence as much. The breeding organization for the Swedish Warmblood is today planning a change towards a linear scoring system.
Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala
There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

The purpose with this thesis is to get a compilation of all the critical bolted joints of all enginesproduced at LV Motors. ABB LV Motors produces induction engines with seven shaft heights. Eachengine size exists several variants of components ex. standard shield and flange shield. Depending onwhich components the engine is equipped with arises various types of strains in the engine's parts,certain assembly ways are more favourable than other.The most critical parts in the engine from a mechanical point of view are the screw units betweenshield/stator, feet/stator and bearing cover/shield.
PERSONLIGHETSFAKTORER OCH RISKY BUSINESS : Vilka personlighetsfaktorer är kopplade till individers riskbenägenhet?
Personlighetsfaktorerna har betydelse för hur mycket risker individer tar. Syftet med denna studie är att undersöka om det finns ett samband mellan personlighetsfaktorerna enligt femfaktormodellen och graden av generell riskbenägenhet. Mycket av tidigare forskning har kopplat personlighet till domänspecifikt risktagande som hälsa, ekonomi och arbete, medan denna studie undersöker kopplingen till generell riskbenägenhet i vardagen vilket kan vara att välja ett okänt resmål eller att söka till en ny universitetsutbildning. 189 undersökningsdeltagare i olika åldrar och från olika yrkesgrupper besvarade en enkät bestående av två olika tester, den svenska versionen av the Big Five Inventory (BFI) och en svensk översättning av the Risk Propensity Scale (RPS). Resultatet visar på ett signifikant samband mellan fyra av de fem personlighetsfaktorerna enligt femfaktormodellen och en ökad riskbenägenhet, nämligen Öppenhet, Samvetsgrannhet, Utåtriktning och Vänlighet.
Skadeförekomst hos häst relaterat till olika typoch mängd av utevistelse
This study was performed to examine whether horses that are kept alone in smallpaddocks are less likely to suffer injuries, compared to horses kept in biggerenclosures with the company of other horses, or not. In not yet published researchmaterial from 2005, risk factors associated with ?accidental injuries? versus ?wearand tear injuries? (represented by trauma injury and fetlock inflammationrespectively), were compared. That material, based on the results of 507 returnedquestionnaires from owners of horses in a Swedish insurance company, includedquestions about paddock/pasture confinement. The results from those questionswere then analyzed in this study in a so called case-control study, in which thegroups with trauma and fetlock inflammation were compared to a healthy controlgroup.The results show that the risk of fetlock inflammation is greater in a smallconfinement, OR for inflammation in a small paddock is 2,2 (95% KI 1,2-3,9)compared to a bigger paddock.
Den offentliga upphandlingens påverkan på entreprenörer : En studie av små och medelstora byggentreprenörer
Public procurement in Sweden is regulated by the Act on Public Procurement (lagen om offentlig upphandling, LOU, in Swedish). The Public procurement in Sweden stands every year approximately for 500 billion Swedish crowns of the taxpayers? money. It is therefore important that the money is spent in the best possible way. The focus in this study is set on the relationship between the small- and medium sized building entrepreneurs and the government.
Kakelugnar : en studie av Emil Petterssons kakelugnsmatriser
In recent centuries the Swedish Tiled Stove has varied in its design with an aesthetic evolutionary history that has not only followed the architectural and artistic ideals but also the taste in stove design. The heat source has varied depending on the regional traditions and where it was located within the country, but the inside of the construction was of a similar five channel system. The purpose of this paper is to study and compare the design of tile matrices made by Emil Petterson with other Swedish stoves. The following questions will be addressed:What characterized the production of a small scale tile stove workroom during the years 1900-50? Which main styles can be described as Emil Pettersson?s ideal while producing his matrices? And finally, is it possible to study the tile stove matrices as objects of historical and cultural significance, and what difficult methodological issues might occur in the doing of it? To answer these questions I will present the results of the documentation of Pettersson?s tile matrices with detailed historical categorizations and schedules. The conclusion shows that Pettersson as a stove builder and -producer was characterized by eclectic ideals and a design shape based on more liberal interpretations of contemporary trends.

Patienters upplevelser och attityder till tandhygienistbehandling, samt ett reliabilitetstest av mätinstrumenten Corah Dental Anxiety Scale och Dental Hygienist Beliefs Survey
The aim of the study was to examine experiences and attitudes to dental hygienist treatment in a group of patients by using the assessment tools Corah Dental Anxiety Scale (DAS) and Dental Hygienist Beliefs Survey (DHBS) at the dental hygienist clinic, the university of Kristianstad. Another aim of the study was to test the reliability of the assessment tools. Methods: Fifteen respondents answered the two questionnaires at two different occasions before dental hygienist treatment. The results showed that nine respondents reported that they are absolutely calm when their dental hygienist is going to remove tartar, while six are a little bit worried or tensed. The categories ethics, communication, trust and control in DHBS had a positive agreement (mean value 1.1 and 1.2).
Lucid dreaming treatment och lucida drömmars relation till locus of control, depression samt subjektivt välbefinnande
Lucida drömmar (LD) innebär att drömmaren inser, under drömmens gång, att omgivningen och händelserna runtomkring är en dröm och inger förmågan att kunna påverka och reflektera över händelserna i drömmen. I lucid dreaming treatment (LDT) får drömmaren lära sig att förändra mardrömmars händelseförlopp. Dock blir inte alla lucida och många tror att det är själva känslan av kontroll som ger en effekt. Studien kommer utforska om kontroll utgör en nyckelkomponent i LDT genom att undersöka sambandet mellan LD och locus of control (LoC), depression och subjektivt välbefinnande där LD verkar som en medierande variabel mellan å ena sidan LoC och å andra sidan depression samt subjektivt välbefinnande. Deltagarna (n = 54) i undersökningen har fyllt i formulär gällande frekvens av drömmar och LD samt formulären Rotter?s 29 item internal-external scale, Center for epidemiologic studies depression scale, International positive and negative affect schedule short form, Satisfaction with life scale och Pittsburgh sleep quality index.
Öronakupunktur mot ångest och depression : En analys av behandling i grupp
Introduction: Anxiety and depression are common among patients enrolled in psychiatric outpatient care. Ear Acupuncture is an alternative form of treatment that has been shown to relieve anxiety and depression in previous studies.Aim: To evaluate ear acupuncture as a group treatment for depression and anxietyMethod: A psychiatric outpatient clinic has been offering group treatments with ear acupuncture for anxiety and depression for 5 weeks. Participants of the study have answered self-rating scales Montgomery Åsberg Depression Rating Scale, Beck Anxiety Inventory and Sheehan Disability scale before and after the treatment period. Material was collected in the period 2008-2012 and has been analyzed in SPSS.Results: Data from 31 patients were included in the study. The results from the study showed a significant difference, between the measurements before and after treatment, with a reduction of the average values in the three different scales.Summary: From this study, it is difficult to draw any conclusions about the effect of ear acupuncture.
Energianalys av tryckluftsystem : så kan Billerud Skärblacka AB spara energi på tryckluft
Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

Vidare fanns ettnegativt samband mellan femininitet och kroppsuppfattning och självkänsla och gällandeandrogynitet fanns ett positivt samband med självkänsla.
Utredning om en ökad biologisk behandling av matavfall i Halmstads kommun
Environment and sustainable development are very current topics in today's society, bothnational and international. The government's bill 2004/05:150 ?Swedish environment objectives - a common commission? contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: ?Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment.
