This Master's thesis aims to investigate the reference interview using the discourse analytical method discourse psychology. The reference interview has been studied thoroughly, and its importance has been proven repeatedly within the field of Library and Information Science (LIS). However, it has never been studied from a discourse analytical point of view before.The material for our study was gathered at Malmö public library, and consists of 10 tape-recorded and then transcribed reference interviews. Our study shows that there are several discourses within the reference situation. The dominating discourse, the reference interview discourse, is found within all the reference interviews.

Erythropoiesis is a complex and carefully controlled process which is mainly regulated by erythropoietin. Using flow cytometry cells in a blood sample can be analyzed one by one. ADVIA 2120 using flow cytometry for analysis of red blood cells (RBC) and reticulocytes. Red blood cell distribution width (RDW) is a component of the RBC method. RDW indicates size variation on erythrocytes and is measured as a percentage of the mean cell volume (MCV). By measuring the RDW anemia can be divided into makrocytic, microcytic or normocytic. Reticulocytes refract light more strongly than red blood cells because they contain some cellular debris. The number of reticulocytes in the peripheral blood reflects erythropoiesis in the bone marrow. The purpose of this project was that by approved methods to establish reference ranges for the parameters, RDW and reticulocyte counts.The individuals who participated in the study, n=124, were considered healthy and had varying ethnicity. Reference subjects had not donated blood the last six months and participation in the study was voluntary.The statistic evaluation includes examination of distribution, and reference ranges for both men and women were established using the 2.5:t and 97.5:t percentiles. The calculated reference interval for RDW was between 12.0 ? 14.3% and the calculated reference interval for reticulocytes was between 38.0 ? 112.8 x109 cells/L. The results showed a significant difference between males and females for the parameter reticulocytes was seen. The difference indicates that different reference ranges should be established for men and women (p<0,0001). No significant difference between males and females were seen for RDW (p=0,74) indicating that the same reference ranges can be used for both men and women. .

Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.

The aim of this master thesis is to find out if young people and librarians think that reference groups can support public libraries to meet the needs of young people, and if the reference groups, which the librarians describe, differentiates from the young peoples requirements. I have made a qualitative study with a questionnaire to six librarians who have experience from reference groups and ten interviews with teenagers. The result showed that young people have many interests and needs which can be met from the library. The teenagers were positive to the library and many of them showed interest in having more influence on the library. Many would like to join a reference group, but on the condition that they would be offered real influence.

The aim of this thesis was to study librarians approach upon reference questions and available resources and also to find out if there is any connection between the nature of the reference question and the choice of resource. The purpose was also to give a deeper understanding of the reference work. Nine librarians were given ten reference questions and their reference work was tape recorded. The study was completed with seven interviews sent by email. Some of the reflections were translated under the headlines of form, subject, time, language and availability.

The purpose of this master thesis is to investigate how librarians working in academic libraries are experiencing the reference situation from a pedagogical point of view, by applying a theoretical framework consisting of learning strategies and their different characteristics, to qualitative interviews. Other goals are to elucidate the fact that learning takes place every day at libraries during the reference situation and that this work must be seen as ?one of the most important activities that takes place at the library?, using the words from one of the interviewed librarians, but also to make place for more discussions regarding pedagogic and library work. This is done by posing questions about knowledge, learning, information literacy, communication, the reference encounter, the roles of the librarian, policy and also architectural aspects of the reference situation. The interviews were taped, transcribed and categorized according to the earlier mentioned areas of interest.

This master thesis is a study of a new electronic library reference service-project called Speak instantly to a librarian and the purpose of the thesis is to investigate a new electronic reference service and how the librarians who work with it experience it. This should be seen from an informational society point of view. The study is conducted from two questions: - What needs do the libraries have and how do they argue for the project and the chat-reference service Speak instantly to a librarian? - How do the librarians experience the personal work situation in the new reference service, and its use of chat technology? Together with interviews of a selected group of librarians from the public libraries of Göteborg, Malmö, Nacka and Stockholm, this thesis includes aspects such as the theory of the informational society by Manuel Castells, as well as literary studies of the history of library reference, the development of electronic reference service and the virtual library, and the background and the beginning of the studied project Speak instantly to a librarian. The thesis also contains an overlook of other similar library projects in the United States of America.

The purpose of this Master?s thesis is to investigate how librarians solve difficult reference questions. The aim is to discuss the nature of reference work ? do librarians make conscious decisions regarding search strategies or do they rely principally on their instincts, or simply chance. The thesis is a qualitative study.

Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

The purpose of this thesis is to study how some librarians working at a public library experience problems that can occur at the reference interview, slightly focusing on communication difficulties. Therefore I interviewed three librarians working at the reference desk on a daily basis. I chose to limit the study to public libraries and to the south of Sweden. My main question is: what difficulties can a librarian encounter during a reference interview and what can he/she do to treat these? In support of my main question I have three subordinated questions:What reasons can there be to a librarian not understanding a user?s information need?What methods are useful for a librarian to enhance the condition of the reference interview? What attitudes and qualities can be of use for the librarian at a difficult reference interview?For the collection of empirical data I chose to use semi-structured interviews.

The aim of this report was to quantify the accumulation of carbon dioxide (CO2) and methane (CH4) in ice-covered lakes in winter (October-March) during three consecutive years, and to assess whether the concentrations of DIC and CH4, as well as the ratio DIC:CH4 differs between years and between lakes affected by clearcutting and untreated reference lakes. Water- and gas samples were collected from four boreal lakes (two affected by clearcutting and two untreated reference lakes) located in Västerbottens inland in spring. The lakes were found to accumulate on average 91, 55, and 84 mgCm-2d-1 during winters 2012-2013, 2013-2014, and 2014-2015, mostly originating from CO2. The concentrations of DIC (autumn and spring) were higher in the affected clear-cut lakes compared to reference lakes for all years, including the reference year (2012-2013) before clear-cutting. No such difference was found for CH4 or the ratio DIC:CH4.

The aim of this study was to examine the social relationships between children and librarians during reference interviews. Using qualitative interviews with five children's librarians I illustrate attitudes and behaviours during a reference situation which take place in psychological, social and even in pedagogical contexts. The literature review comprises studies of the reference interview with children and youth, a description of interpersonal communication and finally social interaction and dialog between teachers and pupils. The main result of this study was the demonstration of a dichotomy in modes of interpersonal communication. In one mode, the social frame is emphasized.

The aim of this master?s thesis is to examine the virtual reference service Ask the Library [Bibblan svarar] from a postmodern perspective. Ask the Library is a Swedish online reference service that is run by the country?s public libraries. The postmodern theories of Jean-François Lyotard are used to study how information is managed and transmitted within the service.

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.
