Säkerheten på en byggarbetsplats : Förhåller sig Skanska och dess underentreprenörer olika till arbetsmiljösäkerhet?

Approximately ten people die every year at building sites in Sweden. Every year TheWork Environment Authority (Arbetsmiljöverket) receives 3200 accident reportsfrom the construction sector. The Swedish building contractor Skanska has the vision:?Zero accidents?. Only at Skanska Sweden, where this diploma work is preformed,350-520 accidents and mishaps are reported every year for the last 5 years.

Kan D-vitamintillskott minska depressiva symtom?

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

Undersökning av mental arbetsbelastning under instrumentflygövningar

En människa har en viss mängd kapacitet för att utföra uppgifter. Om uppgifterna blir för svåra eller för många, det vill säga om den mentala arbetsbelastningen blir för hög, går det inte längre att klara av alla uppgifter och prioritering av de viktigaste uppgifterna blir nödvändigt. Piloter behöver ofta ta in och bearbeta en stor mängd information under instrumentflygning. Ofta måste en del av uppgifterna utföras samtidigt och på begränsad tid. Syftet med examensarbetet är att, med hjälp av en subjektiv mätmetod undersöka vilka moment under instrumentflygövningar som medför störst respektive minst mental arbetsbelastning.

Sociala medier för Knowledge management : Företags användning av webb 2.0 baserade kollaborationsverktyg för kunskapshantering

Knowledge is today one of the most important resources for an organization to handle. But knowledge can also be difficult for organizations to manage. The internet is still growing and new tools take form that allows users to effectively share information. The purpose of this report was to describe how organizations can make use out of internal social media to facilitate knowledge management processes. Three issues involving mapping, coding and dissemination of knowledge to were produced to answer the thesis. The study was limited to examining the identification, coding and dissemination of knowledge through the internal social media plattformen, IBM Connections. The theoretical framework emphasizes how social networks can promote knowledge sharing, how a knowledge mapping can promote knowledge dissemination and sharing, how knowledge can be stored in data sources and how important interaction is to spread awareness. The theory has been supplemented by descriptions of how the system IBM Connections works. Surveys were conducted on four companies that use IBM Connections as an internal communication plattformen. The four companies were selected to illustrate how they use the plattformen of knowledge management processes and we chose to interview the people who were responsible for the introduction of the plattformen. The study identified several similarities between the different companies and that although there were some technical and cultural recalcitrant units against this new type of system within the organization so favored IBM Connections knowledge in several ways. The built-in search automatic created a map of knowledge through the plattform's user profiles. Saved files and documents could be found even after the employees left the company, which encodes knowledge into the company knowledge resources. The opportunity to interact with one another, often over great distances, favored the sharing of knowledge. A comparison with the theoretical framework provided us with the conclusion that internal social media can be used in several ways to Knowledge management through automated knowledge maps, the ability to store knowledge within the company and to communicate knowledge across functional and geographical boundaries in interactive discussions..

Att planera för social hållbarhet i ekobyar :

This essay gives the reader an overview of the different problems and issues a landscape architect might meet, in the process of planning and realizing an eco-village. Its aim is to stimulate new ideas, based on the traditional, present and future working field of landscape architects. The essay does not claim to cover all imaginable aspects of social sustainability within an eco- village, but refers to the presented sources for further in-depth reading. Although the original focus has been on physical planning, the interviewees? words have been of big importance, and to a certain extent changed the constitution of this essay.

Köpa jordbruksmark i Ukraina :

We have chosen to write our examination essay about Ukraine, we wanted to find out what kind of possibilities there is to run a farm there, and also find out what kind of problems that might arise. Ukraine is still heavily influenced by Russia and the legacy from the former Soviet Union. The agriculture today looks pretty much like it did before the collapse of the Soviet system. There are large governmental or cooperatively owned farms. The large farms have to deal with bad cash-liquidity and they often have trouble getting a hold of seed and artificial manure to their whole acreage.

Lean i arbetsprocessen för projekledning

This report presents the results of a thesis in which the department PL Hus at Grontmij AB isstudied. The study has been done in order to locate problem areas in order to streamline andimprove the quality of working. The study was done by an engineering student from theDepartment of Industrial Management at KTH on behalf of Grontmij AB. The project extendedover a period of 20 weeks during spring 2011.In addition to the Department itself has two project managers in two different projects beenfollowed. The method used has been participant observation and was used to be able to comeclose to reality and thus find problem areas where there are opportunities for development.Validation was made through comments and opinions from workers at Grontmij AB, afterreading the reports analysis.Based on a system and holistic approach has parallels been drawn to the production systems suchas TPS (Toyota Production System) and lean production.

Dynamisk modellering av vindkraft : En studie av dynamiska beteenden hos inbyggda vindkraftmodeller i PSS/E

Detta examensarbete behandlar dynamiska vindkraftmodeller i simuleringsprogrammet Power System Simulator for Engineering (PSS/E) som används av Svenska Kraftnät vid analyser av det svenska stamnätet. Syftet med examensarbetet har varit att förenkla Svenska Kraftnäts hantering av vindkraftmodeller vid olika analyser av nya vindkraftparker som ska kopplas in på stamnätet. Detta gjordes genom att undersöka om dagens modellering av vindkraft, bestående av negativa laster och tillverkarspecifika vindkraftmodeller, kan ersättas av en generisk representation med de modeller som finns inbyggda i PSS/E. Rapporten ger en teoretisk beskrivning av vilka tekniker som används i vindkraften idag och hur de vindkraftmodeller som används i PSS/E är utformade. För de inbyggda modellerna i PSS/E har både vindkraftverk med dubbelmatad asynkrongenerator (DFIG) och vindkraftverk med fulleffektomriktare studerats. Resultaten visar att en generisk representation av vindkraftverk med DFIG kan göras med den inbyggda modellen i PSS/E med de parametervärden som finns rekommenderade i denna rapport. I den inbyggda modellen för fulleffektomriktare finns dock begränsningar som gör det olämpligt att använda en generisk representation för denna vindkraftstyp. Övriga slutsatser som dragits är att de inbyggda vindkraftmodellerna i PSS/E inte är tillräckligt flexibla för att fullständigt kunna representera ett dynamiskt beteende från en godtycklig tillverkare i händelse av ett systemfel..

Är vi artiga mot virtuella agenter?

The CASA-paradigm, Computers Are Social Actors, was introduced in the book "TheMedia Equation" by Reeves and Nass. One of their experiments concluded that we tend to be polite to computers in the same way as we are to people. In this study I have replicated Reeves and Nass experiment but instead of a text-based interface I have used a virtual agentin order to find out if we are polite to the agents, or still to the computer. Two experimental setups was conducted. The two setups had a common first part that was carried out on onecomputer with one agent.

Androgynitetens betydelse för det kreativa uttrycket i To the Lighthouse

A growing need to strengthen ones position on the market, even as a city in competition with other cities, has resulted in an increasing number of municipalities developing brand platforms. When the city of Umeå developed their platform, they identified decision makers and investors as one of four important target groups.The aim of this study is to explore the portrayed image of the city of Umeå in two Swedish trade journals which addresses the specific target group decition makers and investors in both public and private sector. The aim is also to compare the image of Umeå in the two papers, to the ambition of the municipality, expressed in the brand platform.In order to make the observations as firmly established as possible, the method of the study is a combination of a quantitative content analysis and a qualitative text analysis. The study draws on the theories of Eli Avraham and Philip Kotler, concerning how to improve city images and how to market a specific city among others. The study shows that the city of Umeå in large extent is portrayed in accordance to the ambition which the municipality expressed in the brand platform.Umeå is displayed as an expanding city.

Artikelbundna instruktioner : Layout och rutiner

This thesis is carried out on behalf of watermixer manufacturer Ostnor AB in Mora.The thesis deals with the area of Article Bound Instructions (ABI) at the company'sassembly department, regarding the layout and management routines involved withthese instructions.In the current situation there are problems with no uniformity in the manner in whichthe ABI is written, then referred to both the civil structure, images and specificityrates in the text.Another problem is that operators do not make use of the ABI that are available inthe current situation, and that there are no clear procedures for who has theresponsibility to write, update and change these ABI.During this work has several people that were identified as key personnel of thethesis held in order to get a handle on how the current situation of the variousobjects of the work looks like, and to examine different desires about the future ofthese should look like from the different subjects perspectives been interviewed.During the work, a number of deficiencies, including that the current program that isused to write the ABI, Lotus Notes, do not possess near the prerequisites for being asimple program to deal with when writing the ABI, which is a condition since wishesare about to put the responsibility for the ABI generation to the departmentsoperators, since their main task is to assemble and do not bother with a program in acomputer.The result of this work has generated new layout and structure of the ABI, designedto be used continuously in the assembly for evaluation, routines regardingresponsibility of the ABI for the Department of Production Engineering (PT),procedures for how the ABI should be written regarding amount of detaileddescriptions in the text and use of pictures.In addition, proposals for further work and improvements has been developed basedon experience during the work and presented at the end of the report..
