Evaluation of the retinal ON- and OFF-responses in the dog ERG
The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from
their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background.
This study shows that the dog ERG has both ON- and OFF-responses and that these responses can be separated by prolonging the flash duration over 50 ms. The dog OFF-response waveform was more similar to the cat OFF-response than the human OFF-response
(Frishman, 2006; Zrenner and Gouras, 1979).
In this study six female three-year-old Beagle dogs were included. Both background and flash stimuli were provided by LEDs (light emitting diodes) with a wavelength of 470 nm, a wavelength that is absorbed almost as effectively by the canine M/L-cones as by the S-cones.
These stimuli gave ERGs with both ON- and OFF-responses.
Green structure planning in Transit-oriented Development (TOD) : a spatial analysis of Önnestad
During the winter 2011 Isaksson and Andersson did a time budget study on Nordens Ark?s Przewalskis horses during daytime when there were visitors and caretakers in the park.

"Hur mycket invandring tål Sverige?" : Invandrings- och integrationsdiskurser hos tre elitskribenter och på Avpixlat- en relationell studie
Drawing on theories of ethnic representations in mainstream news media and racial discrimination (van Dijk 2000, Hultén 2006, Husband & Downing 2005, Wodak 2011), and using methods of critical discourse analysis (mainly van Dijk 1993, 1991, Fairclough 1995) this bachelor thesis aims to investigate the inter-textual and inter-discursive relationship between selected editorial and opinion pieces written by three mainstream right wing ?symbolic elites? and the xenophobic blog ?Avpixlat?. The three selected symbolic elites are: Per Gudmundsson, editorial writer at the second largest Swedish newspaper SvD, Andreas Johansson Heinö, academic with a P.H.D. in political science, specialized on issues of integration and ethnic relations, and Paulina Neuding, editorial writer at SvD and editor in chief for right-wing oriented magazine Neo. All three are actively taking part in the mediated discussion of ethnic relations in Sweden from a liberal-conservative perspective.
ERASMUS-programmets fördelar för deltagarländerna : En studie av vilka fördelar deltagarländerna anser sig få av att studenter studerar utomlands genom ERASMUS-programmet.
The object of this essay was, first, to study what advantages parliamentary members in the participating countries argue that their country gains when university students study abroad via ERASMUS, and, second, to study two factors that might affect what advantages that are emphasised by the parliamentary members in the participating countries. To achieve this object, two research questions were posed regarding what advantages of the ERASMUS Programme are mentioned in the parliamentary debate in three countries, United Kingdom, Sweden and Germany, and regarding whether the parliamentary debate is different between the countries as concerns what advantages are emphasised. Subsequently another two research questions were studied, regarding whether the countries? different positions in Europe and the existence of euroscepticism in these countries affect what advantages of the ERASMUS Programme are emphasised in the parliamentary debate. The study was carried out using argumentation analysis, in which the arguments for participation in the ERASMUS Programme presented in the parliamentary debates were compiled and grouped together according to whether they refer to economic and professional advantages or to cultural and social advantages.

Reaktivitets differens i Novel Object test hos hästar i olika inhysningssystem
Hästen är ett stäppdjur som under en lång tid utvecklat sin flyktinstinkt samt specifika beteendemönster som spänd kroppshållning och fnysningar. Dessa beteendemönster visar sig vid rädsla och har som funktion att varna artfränder för möjlig fara. Utvecklingen av ovanstående beteenden har haft en stor betydelse för artens överlevnad. Att snabbt fly från saker som hastigt dyker upp i synfältet, är hästens främsta sätt att skydda sig mot fara.
Flyktinstinkten har haft så stor betydelse för hästens överlevnad att den inte går att träna bort. Hästens flyktinstinkt ligger ofta bakom flertalet av alla hästrelaterade olyckor som sker.

Pragmatisk förmåga hos barn med hörselnedsättning : En samtalsanalytisk studie om begäran om förtydligande
Different abilities are of importance to pragmatics, there among hearing. Hearing impairment can affect language development and also pragmatic ability. The aim of the present paper was to study the pragmatic ability in terms of request for clarification in children with Hearing Impairment (HI) in conversation with children with no known hearing impairment, henceforth normally hearing (NH). The present study also describes requests for clarification sequentially in detail, and also highlights points where there may be observable differences between children with and without hearing impairment. Eight conversational pairs consisting of one child with HI and one NH child were studied.
Från top down till bottom up : - Att förklara och utvärdera psykosocialt arbete inom hälso- och sjukvården
Today, activities funded with public funds needs to present relevant and reliable information which shows the results obtained. Requirements increase in welfare activities to be run based on scientific, empirical knowledge. This applies particularly to social work. The social work is, however, poorly researched in areas such as knowledge of interventions in the content, context and effects. One way to evidence-base social work can be to conduct regular and qualified assessments.
Yrkesroll i förändring? : En studie av ett antal statsanställda arkivariers upplevelser av införandet av en verksamhetsbaserad arkivredovisning
The aim of this thesis is to examine the archivist's professional role in public authorities and discuss if, and in what way, the profession is effected by the new swedish process oriented archival description system. The study focuses on swedish authorities and does not make any international comparisons with other institutions. Neither does it investigate archivists workingin the private sector, but centers on public institutions.The survey is performed in five swedish public authorities, using interviews and observations. Grounded theory is used as a method initially in the purpose of keeping an open mark towards the object of study. The initial results led on to questions about how well the archivists perceived that communication within the authorities served, and how this in turn prepossessed their work situation and the professional roles in which they found themselves.
Marknaden och kulturarvet: Argumentationsanalys av moderaternas kulturmotion 2005/06Kr:233
The cultural policy area has a tendency to be seen as a consensus area, where there are no big conflicts between the parties. The aim of this master?s thesis is to study the moderate party?s cultural motion 2005/06Kr:233 with the party leader Fredrik Reinfeldt as first author. If consensus rules, the party?s ideology should not be visible in the motion, but the assumption in the thesis is that it is visible.
Tillgänglighet, en förmån eller en avlägsenhet? : tillgänglighet för synskadade på museer och förmedling av arkeologi
This bachelor thesis brings up a discussion about museums availability and access to thearchaeological display objects towards blind and visually impaired visitors. The study phasewill take start in analyzing four museums in south Sweden, all which have exhibitions aboutthe prehistory.Visually impaired and blind visitors don?t have a lot to go on at the current exhibitions aboutprehistory. This is because of the lack of access and availability when it comes to their specialneed. To raise awareness to this problem I took out a survey for the museums to answer.
Jämförelse av programvaror för konstruktion i råa punktmoln
Laser scanning is a method of surveying that has evolved rapidly in recentyears. The technique is based on a laser scanner set up, which can document a structureusing pulsed laser beams. Each time the laser hits a surface it is partly reflectedback to the scanner that stores the point. By using strategically placed targets, storedpoints from different scans can be merged into a point cloud. A point cloud is avisualization of the scanned object with a very high accuracy.
