A comparison of two certification schemes for dairy cow welfare in relation to resource-based, management-based and animal-based measures

Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.

Amning som preventiv åtgärd mot plötslig spädbarnsdöd : En litteraturstudie

ABSTRACTObjectiveThe aim of this study was to determine if and what kind of scientific evidence there is for the advice that breast-feeding can reduce the risk of sudden infant death syndrome (SIDS). The aim was to investigate research on the subject published in the last 15 years.MethodA systematic review without meta-analysis with relevant original articles published in the last 15 years.Main resultsAfter searching for articles 26 relevant articles were used for this study and two were excluded because of poor quality. Mixed results were shown on breast feeding and the risk of SIDS. Breast-feeding seems to have some protective effect but can?t be separated from known risk factors of SIDS.Plain language summaryBreast feeding can be regarded as a preventive measure against SIDS.

Piotroski ur ett riskperspektiv : En empirisk studie av 3- samt 4-faktors CAPM

An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) measure of financial performance, F_SCORE.

Övervikt och fetma hos barn och ungdomar : Orsaker, konsekvenser och åtgärder

The purpose of this essay was to get some knowledge about how the situation was for children with overweight and obesity. I wanted to examine what experience about causes, consequences and measure the professionals, who meets children in different situations in their daily work had, and I wanted to find out which explanations current research had about the problem.The knowledge I have acquired during my work with this paper about the problem was that it was depending on many different factors on various stage in the child's life which influences and interacts with the child in its development. The risk that a child would develop overweight was amongst other things depending on the child's eating- and exercising habits.This habit was formatted for example by the circumstances in the family, availability of sweets/food and the choice of leisure time activities.The consequences for the overweight/obese children could be that the child did not manage to keep up with its friend's physical activities which led to a sense of rejection, risk of being bullied by friends, the risk of a damaged physical and psychic health. The problem was not easy to measure and all of the studies demonstrated that parental involvement is necessary in an effective treatment of childhood obesity..

Metoder för prediktion av kardiovaskulär sjukdom med njurfunktionen

This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..

Han, Tarzan; Hon, Jane?: En studie om skillnader mellan pojkar och flickor i utredningsarbete på en socialförvaltning

The purpose of this essay was to examine whether there were any differences in social workers way of investigating boys and girls, age 13-15. The main questions we wanted to answer were; which were the factors that the social workers focused on? Did the investigations lead to a measure and if so, which one? How were risk and protection factors described and ana-lysed?To answer our questions we read and analyzed 22 reports, written by social workers 2004 at the department for teenagers and families at a social welfare service in Sweden. We came to the conclusion that there were some differences, but these were few and not extensive. Recreational activities was mentioned in a higher degree in the boys reports while health, housing conditions and network were mentioned more often in the girl´s reports.

Riskstatusbedömning : Ett djupgående analysverktyg för sevesoanläggningar

Safety and risk management currently have a starting point based on the negative outcome of safety, thus the lack of safety. The starting point for the thesis is to find a way to measure the positive outcome of safety through ergonomic aspects regarding chemical plants that are covered of the Seveso II Directive.Through a literature study of safety and ergonomics fourteen key aspects of safety were found. Safety Performance Indicators (SPI's) are used to assess the fourteen identified proactive indicators of safety. An analysis in three steps - called risk status assessment - is design to give an SPI its value. A pilot study of the risk status assessment was performed at the ethanol producer Lantmännen Agroetanol in Norrköping, Sweden..

Effektivitetsmätningar i inköpsfunktionen

The objective of this study is to determine if and how Swedish businesses measure the efficiency of their purchasing departments.In this study I have interviewed six medium to large successful companies and asked them· Which ratios they use to measure the efficiency of their purchasing departments· Why they use these ratios and· How the results of these measurements are usedI can conclude that although there are no ratios or other measurements that directly measure the efficiency of purchasing indirect measures do exist.The measures applied are usually the result of demands from management and the results are reported back to management and used to follow development within a particular field of purchasing. Benchmarking, especially external benchmarking, is unusual..

Arbetsbelastning hos flygledare: utveckling av belastningsenkät för flygledningsarbete på mindre flygplatser.

In this thesis, it is investigated if it is possible to create a common factor of the work tasks done by an air traffic controller, which then can measure workload. This will lead to the development of a tool to measure workload at small airports. In the research project a questionnaire is created to measure the different tasks an air traffic controller has. The same questionnaire will also measure the number of environmental factors that exists around the air traffic controller. To measure the validity of the questionnaire, the authors are using NASA-TLX.

Riskpremien, vad ska man tro? : En studie med facit i hand

The market risk premium is one of the most important parameters in finance. Its value and the ways to calculate a risk premium for the market is a widely debated subject. This thesis examines numerous ways of calculating a risk premium for the Swedish market with regard to how good an estimation they make of a real risk premium. Estimations based on historical periods ranging from 20 to 85 years is calculated as well as a premium based on forward-looking estimates. The real risk premium is solved out for a selection of companies and an index with the help of CAPM.

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.
