Planering och Målstyrning : En nulägesanalys av ett markdistrikt inom Skanska

This report is a result of a diplomawork in construction engineering.The goal of this thesis is to highlighthow the work with planning andperformance management is done in theprojects at the Swedish buildingcontractor Skanska Väg & anläggning,region Stockholm/Mälardalen, districtMark Stockholm North, compared toSkanska?s policies.The comparison was made with focus onfive tools for productivity. The toolsare as follow: broken-down schedule,work sets, visual control, performancemanagement/progress monitoring and bestpractice.The study showed that the usage of thedifferent tools varied both within andbetween the different projects.Practically none of the projects whereusing the tools progress monitoring andbest practice, mostly due to fewoperations being applicable. The worksets are now mostly documented, but theyare rarely followed up. Performancemanagement is somewhat inconsequentialfor the moment, but during 2011 targetsheets will be introduced, withtemplates for setting up targets.Scheduling is one of the most importantworks regarding planning.

Sambandet mellan psykisk ohälsa och hälsorelaterade levnadsvanor bland kvinnor och män i en skånsk befolkning

Bakgrund: Daglig rökning och låg fysisk aktivitet på fritiden är betydligt högre bland individer med psykisk ohälsa. Syfte: Att undersöka dessa samband i ett köns- och socioekonomiskt perspektiv, samt eventuellt finna bakomliggande orsaker. Metod: Använder data från en tvärsnittsstudie (Folkhälsoenkät, Skåne 2000) med en representativ population (n = 11 304) i åldern 18-65. Huvudvariabler är självrapporterad daglig rökning och låg fysisk aktivitet, samt psykisk ohälsa som bedöms via General Health Questionnaire-12. Analyser gjordes med logistisk regression för att få oddskvoter och kontrollera för möjliga confounders. Resultat: Samband finns mellan psykisk ohälsa och daglig rökning, respektive låg fysisk aktivitet bland båda könen, och bland socioekonomiska grupper. Kvinnor har signifikant lägre oddskvoter gällande båda sambanden. Individer med psykisk ohälsa har fler ofördelaktiga levnadsvanor än de med ej psykisk ohälsa, oavsett socioekonomisk status.

Prissättningen av bostadsrätter: Vilka faktorer påverkar priserna, vad är riktpriset för en lägenhet?: - En mikrostudie av Södermalm i Stockholm

Those who have invested in apartments, i.e. tenant-ownership, within the city centre of Stockholm have gained a higher than expected return on investment due to a buoyant real estate market. During the latest twelve-month period, the prices have risen more than 20 per cent in the city of Stockholm, resulting in an increased wealth together with a higher debt burden among investors. The aim of this thesis is to investigate which factors determine the prices from a micro perspective, and to what extent. An attempt is particularly made to estimate the degree of capitalization of the monthly fees; a factor which has turned out to be important according to other studies; but also to construct pricing models in order to set target prices for apartments.

Resultatet av 150 års samlande : en dokumentation av Gästrike-Hälsinge nations konstsamling

There is an old saying, that after Epaminondas nothing was ever the same again. In this thesis I will focus on three questions: "Epaminondas the man." Who was he? "Epaminondas the general." How did he change the technique of warfare that made it possible to beat the Spartans? "Epaminondas, founder of cities and wall-builder." How did he build the walls around the cities he initiated, that made them resist enemy attacks for many years to come?While seeking the answers to yhese questions I will make a contextual analysis to get the historical background to all the phenomina involved..

Comparison between anesthesia with sufentanil-midazolam and sevoflurane in medetomidine premedicated rabbits undergoing ovariohysterectomy

Rabbits carry a high risk of anesthesia related death. This study was part of a project to develop a form of total intravenous anesthesia (TIVA) with minimal effects on cardiac, respiratory and metabolic parameters. In the study, TIVA with sufentanil and midazolam (group TIVA, n=9) was compared with inhalation anesthesia with sevoflurane (group SEVO, n=9) in female rabbits undergoing surgery (ovariehysterectomi). All rabbits were pre-medicated with medetomidin and carprofen before anesthesia induction. Anesthesia was induced with TIVA (2.3 ?g/ ml sufentanil, 0.45 mg/ ml midazolam) at a rate of 4 ml/ kg/ h and the mean induction dose was 0.4 ?g/ kg of sufentanil and 0.1mg/ kg of midazolam.

Tidig extubering efter hjärtkirurgi : Intensivvårdssjuksköterskans kunskap om tidig extubering och deras syn på faktorer som påverkar tiden till extubering

Early extubation of cardiac surgery patients has become increasingly important. The assessment of the patient before an early extubation is crucial and the intensive care nurses (ICU nurses) in this estimation is there for very important.The aim of this study was to examine critical care nurses' knowledge of early extubation, and what view ICU nurse has about factors that affect the time to extubation of cardiac surgery patients.A quantitative approach with descriptive and comparative design was used. Selection was all ICU nurses at a thoracic intensive care unit who were clinically active in patient care.The study showed that ICU nurses had good knowledge of why an early extubation was essential. However, the knowledge about the unit?s extubation criteria was low.

Nya sensorsystem för kombinationseffekter av antibiotika

Idag är antibiotikaresistens ett allvarligt problem. En tillfällig lösning på problemet är att utnyttja synergieffekter som kan uppstå mellan olika typer av antibiotika. Det innebär att antibiotika skulle kunna ha effekt mot bakterier som har utvecklat resistens.I denna rapport har flera olika metoder, för att mäta bakterietillväxt, utvärderats. Dessa metoder indikerar om antibiotikakombinationerna har en effekt. Däribland har både kommersiella och nyligen publicerade metoder undersökts.

Bibliotek Plattan : en plats för inspiration, lärande och möten?

The main focal point of this study is about public libraries and its possible roles in today's society. Going from having had a clear educational orientation, public libraries has with time amassed several other roles, which all need to relate to the swedish law regarding libraries and other governing documents, as well as business plans. This thesis focus on a qualitative investigation, which was conducted through in-depth interviews with librarians and other staff at a public library in Stockholm, named bibliotek Plattan, to ascertain the prevailing opinions within this facility about the role of libraries and librarians. The choice of examine this particular library was based on the fact that bibliotek Plattan differs from the public library in general and only offers material for adults. Their collection of litterature is primarily based on fiction novels.

Miljö i fokus - En studie av de bakomliggande drivkrafterna för den ökade miljömedvetenheten inom svensk kemiindustri

BACKGROUND & During the last century, the Swedish chemical industry has developedPROBLEM: considerably in regard to respecting the environment. Following various discharges and pollutions during the first half of the 20th century, environmental concepts such as CSR, Responsible Care and REACH have developed in order to improve the situation. Today, environmental issues play a central role in the society, but what are the reasons behind this increased environmental commitment? PURPOSE & The purpose of this thesis paper is to study the driving forces behindDELIMITATIONS: the increased environmental awareness in companies. Is this mainly due to stricter legislations, or do factors like pressure from the general public, the industry or customers play a more vital role? Furthermore, do economic incentives exist, that make it interesting for companies to invest in environmental awareness? Since the chemical industry spans over a wide spectrum in regard to environmental issues, this paper will focus on a specific area of the industry.

Drama inom den obligatoriska skolan

In this paper, I have conducted a study of what perspectives educational drama has in theory and practice. The study aims to show an example of how and out of what perspectives educational drama is a part of the school?s activity at a geographically distinct school, from kindergarten on to primary and secondary school years. The general attitude of the faculty and their arguments for and against drama constitute the major aspects of this study, which has been carried out through qualitative interviews at a school in Skåne. The results were that pre-school focuses on teaching drama to develop communicative abilities amongst the students (art educational perspective) while secondary school seemingly abandoned this approach and focuses more on using it for personal development, increasing empathy and understanding of other people by taking it to a more emotional level in order to affect for example moral values of the students.

XP ett stöd eller ett hinder?

Detta arbete är en reflektion över ett programvaruutvecklingsprojekt, WAIS, och den arbetsmetodik som användes för detta projekt. Arbetsmetodiken för utvecklings-projektet var Extreme Programming (XP) och vi ifrågasätter om detta val var lämpligt för ett projekt som WAIS. Projektet genomfördes vid Blekinge Tekniska Högskola under våren 2004. Utvecklingsprojektet WAIS var en del av ett större projekt, AIS 42, som stöds av VINNOVA. Huvudprojektets bakgrund och syfte beskrivs för att läsaren skall förstå den roll projektet hade. Studenternas uppgift har varit att utveckla en prototyp för ett system som skall sprida information relaterad till logistik och transporter.

Helsingborg has the intention to build a train tunnel south of Knutpunkten. This report investigates the hydro geological aspects of the project. Questions at issue that will be answered: 1. Which parameters affect the groundwater level? 2. How will these parameters change within 100 years considering climate changes and what will be the consequences on the groundwater level. According to SMHI climate analysis the climate can change causing increasing precipitation, temperature, and a rising sea level.

Spårbarhet i RM-processen ur ett förändringshanteringsperspektiv

Det problemområde som behandlas i arbetet är den del av systemutvecklarens arbete avsett att hantera förändringar i kravbilden under systemutvecklingens hela livscykel, kallat Requirements Management (RM). Arbetet fokuseras på detaljer kring spårbarhet inom förändringshantering.För att lyckas i spårbarhetsarbetet gäller det för systemutvecklaren att se hur de olika krav som finns i kravbilden är relaterade till varandra och var kraven har sitt ursprung. Det skiljs inom spårbarhetsområdet mellan framåt- och bakåtriktad spårbarhet. Vardera spårbarhetsriktningen delas sedan in i två steg från kravursprung framåt via kravdokumentation till realisering då det gäller den framåtriktade och från realisering via kravdokumentation till kravursprung då det gäller den bakåtriktade.En studie har genomförts där litteraturens syn har jämförts med ett antal respondenters då det gäller att dels kartlägga vilka typer av spårbarhet som behövs inom systemutvecklingsprojekt och dels vilket stöd som behövs för att etablera och underhålla denna spårbarhet..
