Situationen för anhöriga till yngre personer med demenssjukdom
Syftet med föreliggande studie var att undersöka hur bra vi är på att bedöma ålder på omaskerade och maskerade ansikten. Syftet var även att undersöka om det fanns systematiska fel som är förknippade med åldersbedömning av maskerade ansikten.Totalt fick 60 försöksdeltagare, samtliga ungdomar, skatta åldern på 60 fotografier av 30 maskerade och 30 omaskerade män. Fotografierna var indelade i två åldersgrupper, yngre och äldre, och samtliga stimulipersoner förekom i både den maskerade och den omaskerade varianten.Resultaten visade att försöksdeltagarna var bättre på att skatta åldern på omaskerade ansikten än på maskerade. Inga skillnader i systematiska fel fans mellan maskerade och omaskerade ansikten.Bilder av unga ansikten skattades med högre precision än bilder av äldre ansikten..
Portal till det förflutna : en arkeologisk kvalitetskontrollerad ämnesportal som resurs för universitetsutbildning i Lund.
The purpose of this essay ("Gateway to the Past. An archaeological quality controlled subject gateway as a resource for higher education in Lund") is to examine how a quality controlled subject gateway could increase the quality of the information supply for the Department of Archaeology and Ancient History at Lund University. The essay gives a brief background to subject gateways and also describes the Department and its subjects (prehistoric archaeology, medieval archaeology, osteology and classical studies) . The essay consists of a questionnaire distributed to parts of the target group as well as an investigation of three particular subject gateways: NordArk, ARGE and The Labyrinth. The essay also contains an exposition of how archaeologists seek information, of the structure of the archaeological subjects and of classification systems for quality controlled subject gateways.
Alternativ uppvärmning av reningsverket på Utö - En studie av energibesparingsmöjligheterna i syfte att minska uppvärmningskostnaderna
The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.
Termisk analys av kompakta jordvärmesystem - Sensitivitetsanalys och korrektions faktorer baserat på fältmätningar i referensanläggningar i Östergötland
Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.
Utvärdering av nya metoder för att finna och värdera risker i ett system
Examensarbetet är utfört vid BAE Systems Bofors AB i Karlskoga. Projektet har gått ut på att utvärdera den nya teorin STAMPoch testa det tillhörande verktyget STPAinom säkerhetsarbete mot det avgränsade ARCHER-systemets delsystem granatgrip-/lyftdon.I dag blir systemen mer och mer komplicerade och de nuvarande metoderna har inte utvecklats i samma takt för att göra en grundläggande säkerhetsanalys då många av olyckorna härrör från oförutsedda interaktioner. Teorin och verktyget är en nyutvecklad metod för att identifiera och värdera risker i ett system eller en produkt. Företaget har ännu inte satt sig in tillräckligt i professorn på MIT, Nancy Levesons rapport som ligger bakom denna nya metod för att arbeta med riskbedömning. Eftersom det är en relativt ny teori inom säkerhetsarbete så finns det inte speciellt mycket forskning att tillgå och antalet källor som finns tillgängliga är få.
Framkomlighetsanalys med hjälp av en digital terrängmodell och kartdata
Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.
Uppföljning inom ett vårdvalssystem - En fallstudie av uppföljningen av husläkaruppdraget i Stockholms Läns Landsting
This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..

This master thesis was performed at IdaInfront AB. The aim of the thesis was toinvestigate how the design principles ofthe user interface in Windows 8 can beapplied to a case management system. Theuser interface in Windows 8 is based ona design language called Metro and it isprimarily designed for touch screens.Ida Infront AB wanted to know whatpossibilities and limitations the Metrointerface offers.The study has resulted in a prototypeapplication that is developed in Windows8. The prototype shows how the Metrointerface can be applied on a casemanagement system. Some limitations inthe usability have been identified inthe Metro interface when applied to acase management system.
System 348 - Rekombinator : Analys av reglerproblematik vid O2
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
?Seriously seeking comics? ? Ämnesbestämning, klassifikation och indexering av tecknade serier
The purpose of this master?s thesis is to examine how comics, here defined as a combination of text and images, are handled by the libraries in regards to subject analysis, classification and indexing. A comparative approach has been used in this study. First, common practices, methods and theories concerning subject analysis developed for documents consisting of text or images are presented. Then the current systems at two special libraries, specializing in comics and consequently dealing with both text and images, are examined and related to the above mentioned practices, in order to discover differences and similarities.
Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning
Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made.
A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.
Tjänsteorienterad arkitektur : Ett arkiv- och informationsvetenskapligt perspektiv på tjänsteorienterad arkitektur
The starting point of this paper has to do with rapid changes within the information technology and the need for agile and fast systems. The primary goal is to investigate what happens with recordkeeping practices in agile environments like service oriented architecture (SOA). It is in the possible transfer between IT architecture and digital archive the area of this paper resides. The paper relates to the Records Continuum model by which records will be considered historical and active at the time of creation. In the Records Continuum model recordkeeping practices and archival requirements will have to be taken into account at the time of creation.This paper concerns SOA from the perspective of Archival and Information science.
Private equity - styrning av tre portföljbolag; En komparativ fallstudie av ett buyout-bolags styrning av tre portföljbolag
By identifying effects that a buyout-firm has on management control systems in its portfolio companies, the aim of this thesis is to explain how such effects differs between the companies and finally to explain why the effects differs even though the companies are owned by the same buyout-firm. The study is conducted as a qualitative case study based on interviews with representatives from the studied buyout-firm and three of its portfolio companies.By analyzing the empirical findings with frameworks and theories within management control systems and value creation, we cannot only identify effects that are common for all portfolio companies but we can also observe differences between the portfolio companies.The identified effects that are common for all portfolio companies are: increased internal reporting burden, increased perceived risk of getting laid off among managers and co-workers and replacement of the board immediately after acquisition.The effects that are observed only for two portfolio companies are: increased focus on short-term planning, higher financial targets, replacement of company management upon acquisition and moving of decision authorities to higher organizational levels. Differences are observed although the portfolio companies are owned by the same buyout-firm due to: differences in management and co-workers equity stake in the portfolio companies, differences in business complexity and differences in planned exit-horizon..
Informationskompetensen i användarundervisningen
This master thesis investigates the user education. Christine Bruce has presented a theory of information literacy in her research which has resulted in seven different aspects of information literacy. In this study I wanted to investigate what aspects there were and what they looked like in a practical educational situation. The methods used for this study were observation and a questionnaire. I analysed the observations by using Bruces aspects of information literacy to group the observed activities into the different aspects.
Användbar användarmedverkan : Är användarmedverkan positivt för systemutvecklingsprocessen?
Computer use at work has risen considerably over the past fifteen years and is currently a relatively common phenomenon when 76 percent of women and 72 percent of men using the computer in their daily work (SCB Arbetsmiljörapport 2009).According to Gulliksen and Göransson (2009), Sweden is one of the countries which are more advanced in the procurement of computer systems at work. He means that Sweden has unique opportunities and conditions for user participation in the development of computer systems, when the user has the right to influence their working environment through a law in the Work Environment Act. The paper examines the importance of user involvement in system development and the Swedish company's approach and experience of user involvement. To highlight and explore the importance of user involvement, there has been a case study in which users have been representative of the development process. The case study has been conducted on a case company where the system IST analys was in need of a new interface.
