Finns det ett samband mellan graden av upplevd arbetsrelaterad stress och copingstrategi hos grundskolepedagoger?

The purpose of this study was to examine whether there was any connection between coping strategies; emotional and cognitive strategy and perceived level of stress among primary school teachers in primary and middle school. It was also investigated whether there was a difference between full-time and part-time employees and perceived level of stress. As a theoretical background Lazarus' transaction theory of stress was used as an explanation of mental stress, Lazarus coping strategies for stress and Karasek?s and Theorell?s model of psychosocial work environment was used to explain unhealthy at work. To measure coping we used Coping inventory resources and to measure the stress we used Percieved stress scale.

Evaluation of a new microarray method for genotyping of HLA-DQ2 and HLA-DQ8 for investigation of celiac disease

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

Den språkliga mångfaldens skola : En studie av språkutvecklande samtal

This study is about what teachers in primary schools say that they are doing to create a school for all.The purpose of this study is to find out what teachers in primary schools say that they do on their mission to create a school for everyone and how they organize teaching to achieve this. The study was conducted as an interview of five teachers from elementary school of different gender and with a qualitative method because it provides a great opportunity to problematize, interpret and understand the responses of the interviewees.The results show that all the teachers think that their mission is to teach so that they can give each student what they need to achieve the goals. This may not be every day but over time, they hope that all students feel that they get so much of the teacher's time that they need..

Att reducera ledtiden i en produktion med hög variation och låg volym - En casestudie på Lab.gruppen

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

Ultraljudssvetsning: ett komplement eller ersättning till symaskinen?

AbstractThis bachelor thesis has been assigned by the company ACG Nyström, Borås. ACG Nyström is working in cooperation with a Swiss company named Jentschmann AG. Jentschmann is a manufacturer of ultra sonic welding machines which ACG Nyström is marketing in Scandinavia and the Baltic States. On behalf of Jentschmann AG the company has the aim to introduce the ultra sonic welding technique to new companies.The aim of this thesis is to compare traditional sewing machines with ultra sonic welding machines within two textile areas, protective clothing and outdoor living.Two investigative questions have been formulated for this purpose: what are the differences between a sewing machine and an ultra sonic welding machine? Is it possible to replace the sewing technology with ultra sonic welding? These stand as guidance for this paper.To gather knowledge interviews, literature studies, and tests on two different ultra sonic welding machines were performed.

Utomhuspedagogik- det outnyttjade rummet

Through a quantitative examination, 26 pedagogies in the pre-school activity answered a few questions in an enquiry about outdoor education. The purpose with this examination was to find out what pedagogies think and apprehend about outdoor education, and also if the "education plan" is in their minds during outdoor activities and if they see them self´s as competent in nature studies. They have also answered questions whether they think that they have good outdoor environment that stimulates children´s development and learning and if there´s any forest that they visit on regular basis.The pedagogies think that during time spent outdoor, it´s the motor skills that are best developed. All of the pedagogies mentioned above think that they need to get more educated in nature studies and also that pedagogies attitude towards time spent outdoors affect the children. They do not think about the goals and intentions of the "educations plan" all the time.

(O)motiverad Invandrarpolitik : en studie om motiven att frångå invandrarpolitik och införa integrationspolitik

An effective Integration policy is important in Sweden while our government has decided and committed to be a country where everybody will be given the same opportunities. There is a greater awareness in today?s society of integration policy goals such as equal rights, responsibilities and opportunities for all. In a number of areas, however, the disparities between immigrants and Swedish-born citizens are still too large.The Swedish Riksdag decided on integration policy in 1997. The main task for this thesis will be to examine the motive behind the Government's decision to revoke immigrations policy and introduce integration policy.

Produktivitet i robotcell

The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the visionsystem.

Inköpssamarbeten mellan oberoende företag

The aim of this paper is to present a case study that increases the understanding of pooled purchasing between independent companies, but also acknowledges the importance of relationships. While previous research has established the advantages and disadvantages of pooled purchasing, our paper shows that successful relationships can render additional synergies and benefits. At the same time, one must consider the time and resources needed to create successful relationships as well as the resulting interdependencies. These implications are well established within the field of purchasing and network theories. However, the authors believe that these implications need to be more explored in regards to pooled purchasing..

Omkonstruktion av treaxlig plockrobot och dess plockverktyg

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

Implementering av en ny chefsroll : Fallstudie av LRF-Konsult

As companies worldwide are in search of competitiveness and larger shares of the market, organizational change has become a key-factor to sustain a competitive edge. But as organizations consist of people, the human aspect of change is not to be disregarded. When change occurs, humans need time to find their new role in the organization, a process that takes time. In this thesis the authors ask themselves what an implementation process of a new managerial role looks like. To answer this question they?ve studied LRF Konsult.

Hantering av varumärken

AimThe aim of the study was to develop a method for the survey of play movement demands and temporal patterns in order to enable a descriptive study of the defensive players in American Football. The overall aim was to  improve the understanding of how American Football is played to create opportunities for enhancement of current or developing new training methods to better suit football.MethodFifty plays from a Division 3 college football game on video from 2005 was divided into sequences of action for one player each from the defensive line, linebackers and defensive backs and analyzed with the video analyzing software cSwing. Every players sequence of action was recorded in a spreadsheet and noted on a scaled football field where distances were measured and together with time stamps from cSwing velocity was calculated.ResultsUsing this method it was possible to describe the play movement demands and temporal patterns which was the main task of the study. The defensive end worked on an average 4.61 seconds per play, the distance was 12.4 meters and average speed 2.5 m×s-1. The linebacker worked on an average 4.35 s per play, 13.7 m and at a mean speed of 3.0 m×s-1.

Hantering av risk i en Leveraged Buyout-miljö: Ägarförändringsklausulen, ett nytt fenomen?

The change of control clause is nowadays a well used covenant in the Eurobond market, with the aims to protect bondholders in case of a leveraged buyout. This thesis intend to evaluate whether the change of control clause is a new phenomenon in the Eurobond market today and to estimate what have been the driven force for the popularity of it. The thesis found that the change of control clause already existed before and thus it is not a new phenomenon. Several factors where found though to explain the extended use of the clause today. Starting in 2005 the LBO activity increased rapidly, exposing almost every company to the risk of LBO.

Riskkapitalbolags inverkan på risk för finansiell kris i portföljbolag: En studie av 53 transaktioner i tillverkningsindustrin

The aim of this small thesis is to investigate if the probability of business failure is higher at the time of divestment than at the time of acquisition for portfolio companies that have been subject to private equity ownership. The background for this thesis is the widespread critique aimed at private equity firms, claiming that they increase the risk in their portfolio companies. We have performed a study of 53 buyout transactions, involving Swedish manufacturing companies, covering a time span of 13 years, from 1995 to 2007. We find evidence of an increased risk of business failure for the portfolio companies with a short forecasting horizon (within one year). The absolute increase in the sample is however small.

Evaluation of lithium-heparintube analyses performance

Today, some kind of laboratory results is required for around 70% of the diagnostics and follow-ups for diseases. In many of the cases the time from sampling to a result is very critical. Therefore the discussion of how to improve this situation has begun. For many analyses serum has been the routine choice for a long time but now it is disputed. After blood collection in a serum tube it is essential to wait 30-60 minutes before centrifugation and analysis of the sample, a long time for someone in an acute state.
