Skiftarbetets påverkan på den upplevda stressen : - en undersökning inom vården

AbstractThe purpose with this study was to get knowledge if there are any possible differences in, and correlation between, experienced stress, experienced demands, experienced control and experienced social support in correlation to shiftwork.The study was made at two central hospitals in south of Sweden and had 90 participants (78 women and 12 men) that answered a questionnaire in the current variables. The result in experienced stress showed that there were no differences between shift workers. The results showed a difference between the day- and the nightshift in the correlation between control and stress. The writers speculates that the reason why the nightshift experience high stressvalues with high control can depend on the lack of presence by higher managers, compared with the dayshift. .

Bättre enskilda avlopp i Sigtuna kommun : möjligheter för bebyggelse i Odensala socken

There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010. A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.

Styrtransmission för bandfordon

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

Effektiv prestationsmätning : en studie av prestationsmätning i kund-leverantörsrelationer

Background: Performance measurement as a management control tool has received considerable academic attention. As the number of inter-organisational relationships, such as customer-supplier relationships, increases, there is a new scope for performance measurement as a management control tool. In order for a company to assess the effectiveness of its supplier relationships it has to define, measure and evaluate variables that are critical for the success of the relationship. The role of management control, and thereby of performance measurement, has increasingly been discussed in theory. However, empirical research in this area is still somewhat limited.

Riskkapital kopplat till handel med spelarkontrakt inom svensk elitfotboll

The aim of this paper is to examine venture capital in football player contracts in Sweden. This is a phenomena that have existed in Sweden since 1999 when the company Djurgården fotboll AB was founded, since then eight other companies have been started. These companies form an alliance with a football club and invest in player contracts. These contracts have high risk since it is valued by the performance of the contracted player. The venture capital firms have no formal control over their investments and they are showing negative results.

Homosexualitet i tre klassifikationssystem under tre decennier: Ett queerteoretiskt perspektiv på SAB, UDK och DDC.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

En studie om förutsättningar för ledarskap i kunskapsintensiva verksamheter

Title: A study about conditions for leadership in knowledge-intensive firms.Authors: Cecilia Ekström and Niklas SandbergKeywords: Leadership, knowledge-intensive firm, hierarchies, followers.Background: Leadership is becoming one of our greatest social myths and is considered a total solution for many problems that occur in an organization. The view of leadership is usually from a top-down perspective, which contributes to an often underestimated view of the follower. Just as it is important to understand the leader's view of leadership, it is important to understand how employees view the structure from which the leader derives its legitimacy. The existing conditions in knowledge-intensive firms, such as autonomy, place special demands on the formal leadership.Purpose: The purpose of this study takes an employee perspective, to understand what the conditions are for formal leadership in knowledge-intensive firms.Method: A qualitative research method was used and empirical material was collected through interviews with employees in knowledge-intensive firms. The empirical material was analyzed by the respondents? mental images which were set against the theoretical framework of the thesis.Conclusions: The conditions for formal leadership in knowledge-intensive firms make it advantageous to have a leader with a withdrawn role.

Reglering av veka strukturer med multipla sensorer

In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.

Design och implementation av konfigurationsverktyg för funktionsblock

Abstract In high voltage substations there is an increasing demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.
