Får elever bättre uppmärksamhetsförmåga efter fysisk aktivitet? : En experimentell studie om fysisk aktivitets påverkan på uppmärksamhet

The aim of this study is to find out whether there is any difference to be found in the attention ability before and after physical activity. The method used in this study was made of an experimental design. The participants were chosen through a cluster sampling and thereafter divided into a control group and an experimental group. A total of 64 pupils from upper secondary school participated in the study, 25 of them in the experimental group and 39 of them in the control group. Since the measure was repeated, both in respect of time and the comparison between the groups, a mixed design was used.

Private Equity-bolags styrning av portföljbolag; En fallstudie av värderingsmodellens översättning till olika organisationsnivåer.

The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.

Sociala relations som skapas i Mmorpg-spel.

Background: It is today common for companies to provide some sort of incentive for CEO's and senior management positions to motivate, retain and benefit employees within a company. This is in order to drive the goals of the CEO and management in the direction that is desired by the owner. Currently, the Swedish centre-right government has forbidden the use of such variable pay within state-owned companies. There are two different attitudes to variable pay, one that is in favour and one that rejects it. However most people agree on the fact that a well-functioning incentive scheme can be of great strategic importance for a company.Approach: has variable pay to CEO's had any effect on the company's profitability.Aim: the aim of the study is to compare companies who use variable pay to CEO's with companies that do not in relation to their profitability in terms of profit margins, yearly performance, returns on total capital and returns on equity.Method: the study uses a quantitative approach.

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.

Psykologstudenters tankar om arbetsliv och arbetsmöjligheter : Ett self-efficacy- och locus of control- perspektiv

Tron på den egna förmågan (self-efficacy) och upplevelsen av kontroll (locus of control) påverkar människors agerande och bedömningar av sina möjligheter. Syftet med undersökningen var att öka förståelsen för hur studenter från psykologlinjen i Stockholms Universitet bedömde sina chanser att få ett arbete direkt efter utbildningen. Fyra studenter deltog i undersökningen och data samlades genom kvalitativa halvstrukturerade intervjuer. Resultatet visade att möjligheterna till att få arbete efter examen ansågs vara goda men att den praktiska tjänstgöringen för psykologer, PTP, sågs som en flaskhals. Erfarenhet, kontakter, ålder, kön och utbildningsinriktning ansågs kunna påverka möjligheterna till att få en PTP-tjänst och påverkade också deltagarnas bedömning av sina chanser.

Trådlös kamerastyrning

As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.
