Socialtjänstens barnskyddsarbete En studie av socialsekreterares riskbedömningar avseende barn som utsätts för våld eller sexuella övergrepp i hemmet.
The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.
Textil fotokatalytisk vattenreningsreaktor: Optimering av beredningsparametrar för titandioxidbeläggning på polyestersubstrat ämnad för vattenrening
I denna kandidatuppsats avlägsnas organiska föroreningar från vatten genom användning av textilier, vars yta belagts med nanopartiklar utav ämnet titandioxid. När titandioxid belyses med UV-strålning sker en fotokatalytisk reaktion, vilket i sin tur bryter ned bland annat bakterier och organiska färgämnen. I hopp om att finna ultimat vidhäftning mot textil passande titandioxid har olika typer av beläggningar studerats; akrylbaserade, sol-gel och slutligen en hybrid. Dessutom har fem olika konstruktioner av textila bindningar jämförts i syfte att undersöka dess påverkan på den fotokatalytiska effekten. Förorenade vatten är ett stort problem, både i utvecklingsländer och i industriella sammanhang.
Driva tulpaner i näringslösning eller i jord :
The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands.
There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.
Smart seed : fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling
Oilseed rape constitutes a good break crop within a cereal dominated cropping system. The normal sowing time for winter rape in Sweden is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time.
Besparingsmodell för produktivitetshöjande arbete inom skärande bearbetningsteknik
The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.
Metodik för fastställande av bärförmåga på befintliga betongkonstruktioner
Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.
Trädgårdsergonomi : om konsten att undvika de vanligaste riskfaktorerna för hälsan i små trädgårdsföretag med krukodling
This paper is based on a literature review and interviews made with managers in small-scale nurseries for pot plant production. The review helped to identify the worst occupational hazards in pot plant production. The interviews provided a way to investigate how the nurseries act so as to avoid the worst hazards and what they do to even out work intensive periods during the season in order to get a more even distribution of work over the year.
According to available statistics problems with back and shoulders are the most common of the physical disorders and the risk for occupational accidents are high for greenhouse workers. Most of the occupational injuries are connected to musculoskeletal problems. The handling of material is often manual and involves frequent lifting and carrying of heavy loads, the strenuous work postures and static muscular tensions these repetitive tasks are associated with causes straining and overloading.
Likabehandling, lika behandling eller bara behandling : En exempelstudie av upplevelsen av likabehandlingsarbetet i skolan
Equal treatment in school is an on-going debate in the Swedish society. At the same time teachers around the country struggles to make ends meet because of a heavy workload. Voices have been raised that teachers no longer have the time to actually be teachers since they get piled up with paper work and other administrative tasks. However, schools are bound by law to take action against harassments and discrimination of any kind. There is also an overall policy in the Swedish national curriculum that every school must embrace diversity and actively teach students about solidarity and respect.
Medborgarinflytande, former och verkan : En studie av motståndet mot etableringen av ett ungdomshem i Kristinehamn 2005-2007
Abstract"Citizen Influence, Forms and Effects - A study of the Resistance Concerning the Establishment of a Juvenile Detention Center in Kristinehamn 2005-2007"Political Science, Johan Utter This essay circles around the concepts of citizenship and the questions if and how citizens in the modern democracy can influence and effect the political decisions made by the governing body on the local level. This is done by the means of a case-study concerning the establishment of an institutional facility for convicted youths in Kristinehamn. The planning of this facility and especially its planned location in Sunneberg aroused a significant negative response from the citizens, demanding a better alternative for the location.The proposition resulted in heavy protests from the citizens as the planned location was viewed as an important recreation area, where the citizens could experience nature first hand, close to the centre of town. As a result, some citizens living close to the planned location, formed a network called "Bevara Sunneberg", whose purpose was to influence the decision-makers and make the citizen?s voices heard.

Arbetsmiljöekonomisk utvärdering av ergonomiförbättringar : Grundade i antaganden om sjukfrånvaro och förändring i arbetsbelastning efter intervention inom en avdelning i läkemedelsbranschen
The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided.
Skattning av parametrar till ordinära differentialekvationer
SammanfattningDet här projektet behandlar området Additiv Tillverkning (AM) för metalliska material och undersöker om det är lämpligt att använda vid produktion inom flygindustrin. AM är en relativt ny tillverkningsmetod där föremål byggs upp lager för lager direkt ifrån en datormodell. Teknikområdet tillåter i många fall större konstruktionsfriheter som möjliggör tillverkning av mer viktoptimerade och funktionella artiklar. Andra fördelar är materialbesparing och kortare ledtider vilket har ett stort ekonomiskt värde.En omfattande litteraturstudie har gjorts för att utvärdera alla tekniker som finns på marknaden och karakterisera vad som skiljer de olika processerna. Även maskiners prestanda och kvalité på tillverkat material utvärderas, och för varje teknik listas möjligheter och begränsningar.
Threats and opportunities for the survival of the Yangtze finless porpoise
The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.
Medborgardeltagande i stadsplanering - En fallstudie av Södra Gårda
This essay examines how public planners and the inhabitants of södra Gårda relate to the physical planning of the area and to the demolition versus the preservation of the quarters Eken and Cedern, and how the dialogue between planners and citizens appears to be. How do the planners and policymakers relate to citizen participation in urban planning, and how is participatory planning carried out in the legislation, rhetorically and in practice. Former research indicates a distinct gap between rhetorics, legislation and actions in practice regarding citizen participation in planning, which is why we find it an interesting topic for further research. The essay aims to highlight the different actors interests and visions of the development of the area. Which are the standpoints and arguments the different actors set out for the future visions of the area? The essay focuses on citizen participation in urban planning in the city of Gothenburg.
