En studie av fysiska, organisatoriska och individuella riskfaktorer hos arbetstagare med datorarbete

Musculoskeletal disorders (MSD) are common in individuals with computer based work. Thecurrently known risk factors for these disorders is in the literature derived to physical,organizational and individual factors. A recent survey of three working groups at a companyin Stockholm explored that more than 50% of the employees had neck and shoulder problems.Aim: The study aims to create a better understanding for the current musculoskeletalproblems at the company. Such an understanding is created by examining the physical,organizational and individual risk factors in the workplace and the result can provide a goodbasis for intervention proposals.Method: In order to answer the aim of the study the authors chosed to use both qualitativeand quantitative methods of data collection through interviews and questionnaire survey. Theinterview and questionnaire was designed to create both a specific and comprehensive pictureof the physical, organizational and individual risk factors having a bearing effect on theexisting MSD problem.Result: Seven categories were compiled from interviews, which largely deals with the factthat high demands can lead to behaviors that may pose a significant risk for the occurrence ofMSD.

Sitkagranens potentiella merproduktion jämfört med vanlig gran i Hallands län

Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden. This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation. The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.

Obesity is a growing problem worldwide among children and adolescents. Previous research has shown that food habits and weight in order children with high and low risk of developing obesity (based on parental BMI) differs between the two groups. It has also been shown that the mother affects the child´s food habits and weight..

Med ryktet som insats: - En fallstudie i tre svenska storföretags ryktesarbete

The purpose of this thesis is to gain understanding of how companies proactively can manage their reputation. The thesis analyzes three multinational companies in Sweden and uses two theoretical approaches - the reputation risk view and the reputation strengthening view - to gain an overall perspective of how companies work with their reputation. It focuses on investigating which key areas of reputation risk the focal companies identify and how they manage the reputation risks within these areas. Moreover, it examines which stakeholders the companies believe are most critical from a reputation point of view and in what ways the companies work with strengthening their reputation among those stakeholders. In order to find a general approach, the thesis investigates the similarities and differences that exist between the respective companies in the study.

Test av icke-kurssäkrad ränteparitet med fokus på riskpremien och möjliga förklarande faktorer

This thesis aims to evaluate the concept of Uncovered Interest Parity. The parity states that the logarithmic difference between domestic and foreign interest rate equals the logarithmic difference between expected future spot exchange rate and the spot exchange rate, . In defining the exchange rate it is often presumed that the parity relation prevails even though several studies suggest the opposite. Numerous economists maintain that the theory?s shortcomings can be explained through the existence of a Risk Premium.

Comparison between different freezing and thawing methods for human spermatozoa

Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.

Effektivisering av urvalsprocesser vid analysering av björnspillning : Ett förslag till den svenska förvaltningen av brunbjörn Ursus arctos

The aim with this report is to formulate a strategic method to optimize selection processes of DNA-samples from a faeces inventory to identify as many individuals in as few analyzes as possible, and by that keep down the costs of brown bear management. Brown bear management in Sweden founds today on results from faeces inventory and is substantially led by the county administration boards. Data from the years of 2004 and 2009´s inventories in Västerbotten was used to test and evaluate different methods in selection processes of which faeces that should be sampled. Comparison were made between making selection by chance, by spatial distribution and by calculating variations in logistic regressions coefficient b, in other words bear density and probability in finding same individual in several faeces. We can show making selection by chance is the most uncertain method.

Effekt av spädningsvätska på spermiemembranintegritet analyserad med NucleoCounter SP-100 :

This study is a part of a larger project where the aim has been to evaluate different methods to assure the quality in stallion semen, due to the fact that some stallions in horse breeding have poor semen quality. The increased use of transport semen requires new methods to ensure good semen quality. In this part of the project the viability and concentration in fresh and cooled semen was examined with NucleoCounter SP-100. A comparison between two different commercially available semen extenders, Kenney?s and INRA 96, was made.

Kommunfullmäktigeledamöters sociala representation -en fallstudie i tre svenska kommuner av kön, ålder och etnicitet

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

Miljöhänsyn inom EU:s sektorspolitik - integrering genom "nya" policyinstrument?

To integrate environmental concerns into non-environmental policy making has become an important policy objective within the European Union. This essay investigates policy instruments in use to achieve environmental policy integration in the EU's transport sector respectively fisheries sector. The point of departure is a theoretical discussion about governance and the use of different policy instruments for environmental management at the EU-level. The focal point is the argumentation that regulatory policy instruments alone cannot achieve environmental policy integration satisfactory. By using Jordan et al's classification of so called "new" environmental policy instruments (market-based instruments, voluntary agreements and ecolabels) as complements to regulatory measures, the essay investigates whether the first-mentioned are used within the two sectors.

Public Sector Scorecard : en ekonomistyrningsmodell med kundfokus

The Public Sector Scorecard (PSS) is a younger version of the balanced scorecard, created for public and nonprofit organizations. The latest model of PSS is divided into three main groups and seven perspectives, while the balanced scorecard consists of four perspectives. Organizations who use either PSS or the balanced scorecard are supposed to have a clear vision spread all over the unit. This study has sought differences between the two models of financial control in both theory and practice. The first part of the study is a theoretical comparison between the models? structures and terms used in them.

Hand Arm RiskbedömningsMetod (HARM) : Utvärdering av en metod för riskbedömning av biomekanisk belastning av övre extremiteten vid manuellt arbete samt dess lämplighet vid arbetsmiljötillsyn

AbstractIntroduction: Hand Arm Risk Assessment Method (HARM) is a tool to assess the risks of deve­lo­ping complaints of the arm, neck or shoulders during manual work. The method was developed in the Netherlands primarily for employers, but is also used as an aid to work environment in­spec­tors. The purpose of this study was to evaluate the HARM-method for assessment of biomecha­nical exposure of the upper limbs when performing manual tasks as well as its suitability to be used within work environment inspection. Methods: Ten labour inspectors conducted assessments of five video-recorded work tasks. Assess­ments made with HARM were compared with those made with the Assessment of Re­pe­titive Tasks (ART) tool and with ACGIH Hand Actvity Level (HAL) - both methods for assess­ment of bio­mecha­nical exposure of the upper limbs - and with the model for the assessment of re­pe­titive work in the pro­visions of the Swedish Work Environ­ment Autho­rity on ergonomics for the prevention of mus­culo­skeletal disorders, AFS 1998:1.
