Studie- och yrkesvägledare samarbete med lärare i skolan : En studie om hur studie- och yrkesvägledare upplevelse kring hur samarbete och tillhörighet fungerar

In this study the author will search on how, co-operation between teachers and guidance counse-lors in school works. The study was too looking for if guidance counselors experiencing if they can feel cooperation in school, when they work by themselves in their profession, and if the guidance counselors feel a part of the whole school.Total interviewed four guidance counselors in elementary school, in a medium sized town somewhere in Sweden. The author have used qualitative methods for allow guidance counselors to answer free and not influence from other parametric.The result demonstrates that all guidance counselors believe that it is important to have coopera-tion with teachers in schools. Most of the guidance counselors believe that neither the directors nor teachers really know what skills guidance counselors possess. The respondents describe that they often turns to teachers who believe that guidance is an important part of the school's work for students..

Clinical and subclinical mastitis in dairy cattle in Kampala, Uganda

Dairy farming in Uganda provides a source of food, employment and income. Previous studies have revealed high frequencies of bovine mastitis, a costly disease for the dairy farmer. The aims of this study were to investigate the bacteriological panorama in milk from udder quarters with clinical (CM) and subclinical mastitis (SCM) and to determine the antimicrobial susceptibility in staphylococcal isolates. Further, we intended to establish the prevalence of subclinical mastitis and to investigate some environmental factors and animal properties that might influence the frequency of mastitis. For CM, farmers made contact with the members of this study when recognizing an animal with CM.

Konstruktion av current conveyors via makromodellering

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Ventilationseffektivisering i skolbyggnader :

Studien går ut på att jämföra tre olika styrsystem för ventilation, nämligen CAV (Constant Air Ventilation), VAV (Variabel Air Ventilation) och DCV (Demand Controlled Ventilation). Dessa styrsystem ställs mot varandra i tre olika lokaltyper, med syfte att identifiera det mest energieffektiva styrsystemet. Ett syftet med studien är också att upptäcka vid vilka flöden det lönar sig att arbeta med VAV- och DCV-styrsystemen..

Ultraljudsmätare för bubbelfälla

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

Internationell operation - Nationellt intresse

Kalla krigets slut innebar helt förändrade säkerhetspolitiska förutsättningar för de flesta stater. Då var världen uppdelad i två tydliga block med två styrande supermakter i ständig dragkamp medan vi idag har en annan verklighet med många olika allianser och asymmetriska hot av olika slag. Denna säkerhetspoltiska omdaning har också påverkat det vetenskapliga studiet av internationella relationer och framförallt under 90-talet deklarerade flera forskare det liberala perspektivets seger över realismen. Denna uppsats är en fallstudie som tittar närmare på Europeiska unionens första marina insats, EUNAVFOR - Operation Atalanta och särskilt på Sveriges deltagande i den samma. Syftet är att söka efter de motiv som läggs fram för insatsen i såväl FNs resolutioner som EUs och Sveriges riksdags beslut för att sedan analysera dessa utifrån de två grundläggande vetenskapliga perspektiven inom internationella relationer. Studien visar att sanningen ligger någonstans mitt emellan dessa två motsatta perspektiv. Båda förhållningsätten innebär ett antal antaganden och förenklingar vilka leder till blinda fläckar i studien och först när man ställer dem emot varandra framkommer helheten. Sveriges deltagande i operation Atalanta kan alltså förklaras av både strikt nationella motiv och av ett delat ansvar inom världssamfundet..

En återvunnen och återanvänd förskola : Hur barn lär sig betydelsen av återvinning och återanvändning

This thesis means to find out how preschool teachers are working to demonstrate the importance of recycling and reuse for children. My hope is to contribute knowledge about various practical methods to establish the idea of sustainable development in the operation. I have used the method of qualitative research and done semi-structured interviews with preschool teachers on certified green flag preschools. The questions I have asked for example concerned how the preschool teachers have worked with recycling and reuse, how much the children have been able to influence and if other didactic subjects are implicated. Six interviews were made and these are summarized in the result part.

Psykosocial   arbetsmiljö   och   besvärsförekomst    bland   flygplanslastare

The purpose of this study was to describe perceived psychosocial work environment and musculoskeletal complaints among baggage handlers, and to evaluate whether there is any linear relationship between them. The study is a questionnaire based cross-sectional study, and part of an ongoing larger project. Therefore, the number of forms has been limited to those that were collected in the project by 2010-11-25 (N=117). The questions analyzed in the study come from the Copenhagen Psychosocial Questionnaire and ?Nordiska Ministerrådets formulär om besvär i rörelseorganen?, respectively.

NATO 1989-2015 : NATO:s säkerhetpolitiska arbetsprocessfrån 1989 till 2015 sett utifrån Berlinmurensfall och konflikten i Afghanistan

The main purpose with the essay is to look into NATO and annalise how the organisation haschanged it´s security policy work process today 2015, seen from two different world eventsduring the period 1989-2015, the collapse of the Berlin wall and war in Afghanistan. Purposeand issuses also apply based on two theories Anarchymodel and World society model. In orderto highlight two different ways to see NATO:s security policy work process over time untilthe present day.Issues:? How did the fall of Berlin wall in 1989 change NATO:s security policy work process?? How did the war in Afghanistan in 2001 change NATO:s security policy work process?The essay is a qualitative method literature review describing NATO as an organisation andworld events that had impact on NATO over time.The result show that NATO has shifled it´s borders further fast because ?new? membercountries from the former Soviet Union are party members. NATO has moved closer toRussia, and increased in momentum.

Marschen mot Bagdad : 1st Marine Division

Denna uppsats avhandlar 1st Marine Division och deras väg in i Irak under operation Iraqi Freedom. Syftet med uppsatsen är att verifiera om det var konceptet manöverkrigföring som 1st Marine Division använde sig av under invasionen? Det har sagts att amerikanerna använde sig av manöverkrigföring i denna operation. Jag ställer mig mer frågande om det verkligen var det konceptet som de använde sig av.För att svara på frågeställningen har jag först beskrivit vad manöverkrigföring är, därefter har jag gjort en fallstudie på 1st Marine Division och deras agerande under invasionen av Irak 2003. Vi följer divisionen från utgångsgrupperingen i Kuwait tills divisionen är inne i Bagdad.

Pedagogik för blogg : "när skolan blir viktig och på riktigt"

In this essay I examine if socio cultural theory is present for teachers when pupils and students are using computers in class, especially when using blogs as a tool for learning. The aim of the essay is also to examine if blogs among pupils in class can promote peer support, co-operation and reflective dialogue, and in that case in what way. The essay consists of two studies, one small interview study and one literature study.  The interview study is made with the qualitative method phenomenographic analysis, presenting four Swedish teachers who have much experience using blogs in education. The aim of the literature study where some national and international research studies of relevance are presented, is to broaden the perspective.The result of the interview study shows that a socio cultural theory is highly present among the teachers who already use blogs in education. In addition, those teachers experience that the blog in the classroom supports dialogue and co-operation among the pupils.  In contrast, the literature study shows that most teachers in Sweden who made their pupils work with computers in classroom seem to let their student work alone, without guiding them and without creating co-operation or dialogue in the classroom.

Can increased activity recorded with help of activity monitoring sensor indicate an upcoming calving?

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

Samverkan och samordning för nyanlända flyktingar : En kvalitativ studie om etablering på arbetsmarknaden i två kommuner

This study has an integration policy direction as it focuses on the qualification for the new arrivals to quickly establish themselves in the labor market, and how the government's interventions, which in this case is the establishment reform, have affected municipalities and what its role is in this context. The purpose of the establishment reform is to faster the new arrivals integration in to the labor market. The aim of this study is to analyze the interaction factors that is affecting the integration of new arrivals into the labor market by study the professionals opinions on the interplay between involved organizations in two municipalities before and after the establishment reform. Studies have shown that the establishment reform has not achieved its goal and the purpose is to analyze the aspects behind this problem. The results of the study were analyzed with help of the interaction theory and the new institutional theory which is a part of the organization theory. An important aspect in the results of our study is the deficiency with the interaction between the participating organizations that obstruct the new arrivals path to becoming self-contained. In order to identify the problem, the study focuses on the co-operation among two communities in Sweden with the new arrivals way into the labor market.
