This user study was carried out at the library at Chalmers University of Technology in Gothenburg in the spring of 1999. Chalmers wanted to investigate how much their employees use electronic journals. To facilitate decision-making and be cost effective, the library needed to know about their customers' opinions. The main purpose was to investigate the usage of electronic journals, how the library's choice of these journals affects the frequency of use and what the attitudes towards them are. A questionnaire was sent out to 2 400 employees; 477 replies were received.

AbstractThe aim of this present study was to investigate whether there is a relationship between birth order and the personality trait narcissism using 181 individuals from Finnveden High School in Värnamo (115 females, 60 males, mean age 17, sd=0,94), in the context of the proposal of Sulloway (1996) that personality is influenced by the specialized nich-es siblings adopt in the quest for access to parental resources. A questionnaire which in-cludes Narcissistic Personality Inventory test, Birth order test and also Rosenberg?s self-esteem test in order to investigate if it might has an impact on narcissistic personality trait, was used. Results showed that there was no significant relationship between birth order and narcissism, however, a significant relationship between narcissism and self-esteem was found. Furthermore, there was a significant relationship between narcissism and the individual?s relationship with the mother.

The purpose of the literature study was to describe older people´s difficulties and attitudes to take several drugs. Literature has been sought in two large databases and included literature is selected, quality assessed and analyzed, based on the study purpose and questions. The authors conducted a descriptive literature review of qualitative and quantitative articles. Difficulties to access different types of pharmaceutical packaging, or to remember when to take their medicines are difficulties the elderly encounter. Cultural and socioeconomic differences become apparent.

Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

The purpose of our qualitative study is to investigate how the caretakers, in the elderly care,interpret and manage the issue of alcohol problems in elderly people. We have beenperforming semi-structured interviews on 9 people, on different levels in the elderly care.There were 3 elderly care managers, 1 nurse, 1 assistance administrator and 4 auxiliarynurses, who all, at some level, work with alcohol problems in elderly people. Thoseinterviews were performed singularly, with one exception: we interviewed an elderly caremanager and her 2 auxiliary nurses at the same time. To analyse our empirics, we have usedthe theories of Power and Ageism. Our study shows that the auxiliary nurses, who are theones who must deal with these problems, have great difficulties to perform their work becausethey have no qualified knowledge about alcohol problems.

Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.

The aim of this study is to examine reading on the MobileReadforums. The term ?to read? is extended to also cover bookcollection and usage of new technology such as mobile readerunits.A catalyst for reading on mobile reader units seem to be the needto always have access to the personal e-book collection. Apartfrom being a source for reading the collection of e-books alsoserves the purpose of extending the members self-esteem.A large portion of the activities on the MobileRead forum isaimed at making new technology comprehensible with the help ofprotocols to determine the usage of that technology. The processof making protocols also seem to be another way for the membersto extend their self-esteem.Traditional libraries are mainly seen as one of many sources for ebooks.Librarians are mostly perceived as being service mindedbut lacking in e-book knowledge.There is also a risk for miscommunication as the library hasdeveloped other protocols that defines an e-book and how itshould be used.This study is a qualitative analysis based on forum posts collectedfrom the MobileRead forum..

The objective of this study was to investigate how the local newspaper readers felt about reading the local newspaper in a tablet device, such as the iPad. We wanted to study the attitudes from consumers towards tablets and if the traditional local newspaper can be substituted with a tablet device. We decided to use qualitative interviews as our method. The selection of respondents was based upon age, whether or not they had a subscription and if they owned a tablet device or not. We accomplished fifteen interviews with respondents living within the area where the newspapers of Barometern and Oskarshamnstidningen are spread. The study shows that the majority of the respondents who already had a subscription tended to lack interest in changing their traditional newspaper consumption. Their habits of reading the local news on paper were strong.

Thermal fatigue is a serious problem in todays power plants. A large amount of damages around the world circles around that subject. The damage can come from the mechanism of two flows mixing with different temperatures in a T-junction. It is a fundamental prerequisite that these T-junctions are frequently tested for damages. An amount of criterias steers the rate of testings.

Värmesystemet i kvarteret "Skruven" i Danderyd betjänas av en fjärrvärmeväxlare kompletterad med kondensorvärmen ur en kylmaskin. Målet med analysen är att bedöma hur systemet kan optimeras för att utnyttja kondensorvärmen så mycket som möjligt. Kondensorvärmen är i princip gratis då kylan maskinen producerar är nödvändig för verksamheten i fastigheten.En beräkningsmodell skapades i Microsoft Excel där anläggningens karakteristiska temperaturer och massflöden kan beräknas utifrån given utomhustemperatur och avgiven effekt ur kondensorn på kylmaskinen. Till modellen läggs energiberäkningar utifrån utomhus-temperaturer uppmätta i SMHIs mätstation i Bromma var tredje timme år 2009.En kostnadsanalys av hur förändringar i driftsättet påverkar hur stor del av den avgivna kondensorvärmen som kan tillföras värmesystemet har utförts. I analysen används Norrenergis kostnadsstruktur för fjärrvärmedebitering samt den beräknade kostnaden för den el kylmaskinen förbrukar.Fjärrvärmekostnaden i modellen uppgår till 219 000 kr/år, utan förvärmning kostar den 630 000 kr/år.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

Purpose: This thesis aims to study how students in upper secondary school evaluate sources in their everyday school work and how the role of the school library and librarian officiate in this context.Methodology: A web questionnaire was conducted and 155 students from different schools, with or without school library and school librarian, participated. We coded and aggregated the questionnaires according to the strategies that are used when evaluating sources, identified by Francke, Sundin and Limberg. Cognitive authority, a theory by Patrick Wilson, was also a part of our analysis. Conclusions: The study shows that students use different strategies, separately or combined, as a way to evaluate sources. The teacher is regarded as a cognitive authority and is the main influence concerning source evaluation. It also shows that the role of school libraries and school librarians, in this context, seem to be non-existent.

The main purpose of this thesis has been to identify and discuss problems connected with the preservation of newspapers in Sweden. Another purpose was to see if the preservation of newspapers has been influenced by the fact that preservation studies in general concerns printed monographs and digital materials. This qualitative study is partly based upon interviews with four librarians experienced in working with newspapers and preservation. The thesis deals with cultural heritage in general and on a more specific level with newspapers where the following questions are dealt with: Why preserve? Who preserves? How to preserve? and What is preserved? Strategies used for preserving newspapers such as paper, microfilming and digitization are described as well as legal deposit, the Swedish microfilming programme and TIDEN, a digitization project of newspapers.
