Peer-to-peer som företagslösning

ProblemomrÄde: Idag Àr anvÀndandet av peer-to-peer (P2P) - applikationer sÄsom KaZaa, ICQ och Seti@home utbrett bland privatpersoner. AnvÀndningen inom företag Àr dock Ànnu i sin linda. Vi kommer dÀrför i den hÀr uppsatsen utreda om ett eventuellt införande av P2P- teknik i ett företagsnÀtverk ger nÄgra fördelar jÀmfört med en klassisk Client/Server-lösning. Hypotes: Arbetet bygger pÄ hypotesen: ?En P2P-lösning ger fördelar för företaget jÀmfört med en Client/Server-lösning? Genomförande: För jÀmförelsen mellan P2P och Client/Server definierades och jÀmfördes fem omrÄden: SÀkerhet, AnvÀndbarhet, TillgÀnglighet, Bandbredd samt Utrustningskrav. Slutsats: Inom omrÄdena AnvÀndbarhet och TillgÀnglighet ger en P2P-lösning klara fördelar, dÀremot inom omrÄdena SÀkerhet och Bandbredd visar Client/Server- lösningen istÀllet klara fördelar. OmrÄdet Utrustningskrav Àr oavgjort dÄ det inte finns nÄgon mÀrkbar skillnad pÄ lösningarna. SÀkerhetsproblemen Àr P2P-teknologins akilleshÀl och det problem som Àr mest troligt att stoppa stora investeringar i framtiden om det inte löses. Slutsatsen av vÄr jÀmförelse blir sÄlunda: För ett företag som redan har ett existerande Client/Server-nÀtverk Àr det inte nÄgon idé att helt byta system, dÀremot kan det vara av intresse att introducera en applikation som möjliggör skapandet av sÄ kallade Virtuella NÀtverk. För ett helt nytt företag kan skapandet av ett P2P-nÀtverk vara ett vÀl sÄ intressant alternativ till Client/Server.

Att mÀta bibliotek: en studie av tvÄ biblioteks verksamhetsberÀttelser.

During the late twentieth century, political and societal changes gave rise to an increased interest in performance evaluation in public organizations. This development also affected libraries in the public sector. The main concern for this master thesis is performance measurement in libraries. In this study two different types of libraries are investigated, one public and the other academic. My aim is to find out if and how performance measurement appears in the libraries annual activity reports.

Genusvetenskapens utveckling inom B&I : en bibliometrisk studie av studentuppsatser med genusperspektiv

The main purpose of this two year masterÂŽs thesis is to study patterns, structures and relations within gender studies when combined with Library and Information Science(LIS). Further aims are to determine the character of student work considering, occurrence, gender and main theme, to study the progress of the intellectual base of gender studies within LIS and to evaluate the use of bibliometrics as a tool for researching the development of a discipline. To achieve these aims, a bibliometric study using both publication analysis and citation analysis, is carried out. The studied material contains student work, specifically focused on gender, from the Swedish School of Library and Information Science (SSLIS) from 1985?2012.

Risk och osÀkerhet vid intrÀde pÄ den svenska apoteksmarknaden: En studie om nya aktörer pÄ en marknad under omreglering

The Swedish pharmacy market will be re-regulated in July 2009 which will present private actors with an opportunity to enter the market. Several risks and uncertainties are associated with such an entry. The purpose of this thesis is to increase the understanding of identification and management of risks and uncertainties associated with entering the Swedish pharmacy market. We also intend to investigate similarities and differences in risk identification and risk management as well as create an understanding of the underlying reasons for these similarities and differences. Three companies interested in entering the market have been interviewed and the interviews were conducted with an open approach to avoid influencing the companies? answers.

XML som informationsbÀrare för EDI

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.

KONCEPTUELLA STUDIER AV SCIENCE FICTION-VAPEN : Hur uppfattas och pÄverkas konceptgrafiken av konceptuella studier gjorda pÄ sciencefiction-vapen.

Denna uppsats behandlar svenska börsnoterade fastighetsbolags tillvĂ€gagĂ„ngssĂ€tt att vĂ€rdera sitt fastighetsbestĂ„nd. BĂ„de nĂ€r det kommer till metod och typ av vĂ€rdering (graden av intern kontra extern).Vidare undersöks faktorer som stĂ„r till grund för dessa och hur företagens vĂ€rdering har förĂ€ndrats sen en kortare tid tillbaka.Uppsatsen kombinerar analyser av finansiella Ă„rsredovisningar frĂ„n svenska börsnoterade fastighetsbolag med ett par kvalitativa intervjuer med nĂ„gra av de högst respekterade och uppsatta personerna i fastighetsvĂ€rlden.Analyserna visar pĂ„ att en majoritet av fastighetsbolagen anvĂ€nder en hög grad extern vĂ€rdering tillsammans med avkastningsbaserade vĂ€rderingsmetoder. Även en förĂ€ndring av fördelningen mellan intern och extern vĂ€rdering under de senaste fyra Ă„ren konstateras och reflekteras över.I intervjuerna jĂ€mförs bland annat interna och externa vĂ€rderingars riktighet och trovĂ€rderighet ur tvĂ„ vĂ€ldigt olika perspektiv. HĂ€r tas Ă€ven problematik upp och skillnader i teori och praktik..

Är Kinas upphovsrĂ€ttslag förenlig med TRIPS-avtalet?

Since the beginning of the twenty-first century, China has captivated global attention due to its astonishing economic growth. This development has resulted in an enormous growth in foreign direct investments, as well as the country?s new role aseconomic super power. When joining the World Trade Organization in 2001, China agreed to adhere to the minimum requirements of the organization?s several multilateral agreements.

Kvinnor i kommunala nÀmnder : En kvantitativ studie i kvinnopolitisk representation

Over the last decades there has been a steady increase in the representation of women on the political arena. Despite of this there are still fewer women in comparison to men in political organs particularly at the municipal level. It is therefore of great importance to examine which different factors that tend to effect the female representation at this level. Doctor of philosophy at UmeÄ University Jessika Wide presented in a study from 2000 that the share of women in the municipal councils tended to depend upon cultural, socio-economical and political factors. Other scholars also mean that women have specific interests and therefore are more represented in some areas.

Biblioteken, upphovsrÀtten och de nya medierna

The explosion of new digital media puts pressure for developments within copyright law both in Sweden and internationally. These developments are taking place on two different international areas: (1) WIPO which is a part of the UN family and (2) the EU where a new directive on copyright law is being prepared and probably implemented during 2001. The aim of this thesis is twofold: (1) to study which considerations libraries must make when handling the new digital media both under today's copyright laws and under those which are being developed internationally. (2) What will be the consequences, for Swedish libraries, if the new EU-directive on copyright law is implemented in Sweden? By analysing current copyright laws, international treaties and the proposal for a new EU-directive as well as the national debate the thesis brings attention to a number of central issues for libraries.

Arbetsmiljö - En jÀmförelse mellan svensk och dansk lagstiftning

The purpose with this essay is to give the reader an insight into and to describe the Danish Work Environment Act in its current wording and then compare it with the Swedish Work Environment Act. The first part of the essay describes the Work Environment Act and after that I compare with the Swedish Work Environment Act. At the end of the essay I will give my own thoughts of the result of this essay. I have chosen not to describe some of the chapters of the Act, for example the chapter about technical means and materials, because of the less importance for this essay and of my own interest. I have also chosen not to make mention of individual professions.

Genusforskares informationssökningssituation

This Masters thesis concerns difficulties experienced by Gender Studies researchers in an information seeking context. The aim is to identify, and study the cause of, these potential difficulties by asking the following questions: How do researchers in Gender Studies seek information? What difficulties may arise when information seeking is carried out in Gender Studies? What may be the cause of these difficulties? What does Gender Studies consist of? In order to find feasible answers to these questions, particular attention is paid to the context in which the researchers exist and work. The database KVINNSAM serves as an example of how libraries have tried to overcome barriers in information seeking in Gender Studies. The method used is a qualitative one based on interviews and literature studies.

Den Moderna Webben: Kan HTML5 konkurrera med traditionell programvara?

Vi ser en förÀndring i hur vi anvÀnder applikationer. FrÄn att tidigare varit associerat till en dator och begrÀnsat till ett par operativsystem finns de numera överallt. Fler plattformar innebÀr att man mÄste utveckla en applikation till var och en av dessa. Detta gör att utvecklingstiden och kostnaderna ökar och efterfrÄgan av crossplattformlösningar i form av webbapplikationer har dÀrför ökat. Vi tittar nÀrmare pÄ hur det gÄr att anvÀnda sig av HTML5, och övriga tekniker som en modern webblÀsare har integrerat stöd för, för att utveckla webbaserade applikationer. Vi tar reda pÄ om det finns nÄgra hinder eller begrÀnsningar i detta och om det finns nÄgra fördelar i att anvÀnda webben som plattform. Resultatet indikerar att med de nya tekniker som Àr pÄ ingÄng kan man utveckla webbbaserade applikationer med prestanda motsvarande Java eller C#.

FrÀmlingsfientlighet i tidigmoderntid : en studie i Olaus Petris "En Swensk Cröneka"

Syftet med denna uppsats blir att ta reda pĂ„ hur reformatorn Olaus Petri uttryckte sin frĂ€mlingsfientlighet och mot vem eller vilka den riktades. Med frĂ€mlingsfientlighet menas i denna uppsats inte bara rĂ€dsla för utlĂ€nningar utan ocksĂ„ rĂ€dsla för det som var annorlunda trots att det betecknades som svenskt. Reformationen var inte bara en religiös och andlig företeelse. Den gjorde ocksĂ„ ansprĂ„k pĂ„ att vilja styra hur mĂ€nniskor skulle tĂ€nka och agera i det dagliga livet. ÄndamĂ„let med denna uppsats blir förutom det ovan nĂ€mnda att ta reda pĂ„ vad som föranledde Olaus Petris frĂ€mlingsfientlighet.

Bibliotekarieutbildningen vid BHS 1977 t.o.m 1999 En diskursteoretisk studie

The aim of this master thesis is to investigate changes within four discourses identified in the curriculum material of the Swedish library education in BorÄs Bibliotekarielinjen dating from 1977 and 1985 and its successor Library and Information Science Biblioteks- och informationsvetenskap dating from 1995, 1999. My method used is a text analytic method primarily derived from the discourse theory of Ernesto Laclau and Chantal Mouffe, yet with addition of tools from the critical discourse analysis of Fairclough. By identifying three floating signifiers within the material, i.e information, library, and librarian, and thereafter identifying their fixation, a pattern of resemblance and diversity in the fixating signs appeared between different courses of the curriculum dating from 1999. Hence I could establish an order of discourse consisting of four library discourses, a knowledge organisation discourse, a user discourse, a society discourse and a management discourse. Using this discursive order as a pattern, I could trace these four discourses back in time within the material dating from 1995, 1985 and 1977.

Förlorad i övergÄngen frÄn aritmetik till algebra : Hur gymnasieelever översÀtter aritmetik till algebra

The aim of this thesis is to look for signs of students? understanding of algebra by studying how they make the transition from arithmetic to algebra. Students in an Upper Secondary class on the Natural Science program and Science and Technology program were given a questionnaire with a number of algebraic problems of different levels of difficulty. Especially important for the study was that students leave comments and explanations of how they solved the problems. According to earlier research, transitions are the most critical steps in problem solving.
