Caso Skanska
Caso Skanska is an incident that occurred in Argentina and regarded corruption and bribes to government officials. This study investigates how this incident could occur and how it can be explained. The theoretical framework used is the dynamic interaction model, stakeholder theory, embeddedness theory, the political perspective and corruption theory. The method used is qualitative and it consists of data gathered through semi-structured interviews in Sweden and Argentina as well as other sources of written information of relevance for the study. The authors conclude that Caso Skanska could occur due to the lack of strong institutions as well as transparency.
Egyptiska universitetsstudenters åsikter om det egyptiska utbildningssystemets förutsättningar att främja en demokratisk utveckling i Egypten
The purpose of this essay is to examine Egyptian university students´attitudes about the Egyptian education system´s ability to support a democratic process in Egypt. In order to carry out my study, scientific books and articles have been read and interviews have been made among Egyptian university students. The interviews contained questions about the Egyptian education system´s impact on the democratic process in Egypt and which impact the Egyptian education system has had on the Egyptian revolution.The conclusion drawn from my study is that Egyptian university students find the contemporary Egyptian education system based on authoritarian rules and with a lack of democratic values. The Egyptian university students believe that to establish democratic institutions in Egypt, the Egyptian citizens need a better understanding about democratic values. However, some of the students believe that the democracy that should be established in Egypt, must be based on Islamic values and to succeed with that, Islamic studies must play a greater part in the Egyptian education.When it comes to the Egyptian education system´s impact on the Egyptian revolution the Egyptian university students´opinions were somehow divided. .
Konflikter på jobbet : En kvalitativ studie om enhetschefens dialog med medarbetarna i konfliktsituationer
The aim of this study was to get knowledge of the communicationprocess between the branch head and the co-worker in communal geriatric care. To narrow it down we focused on how the branch head experience the communicationprocess in conflictsituations between co-workers and what she or he usually do to resolve the conflict. We made qualitative interviews with ten of the branch heads in communal geriatric care, in four communes. The questions we had in mind throughout the study was based on four keywords (communication, leadership, conflict and conflict management) of which we created a narrative story from every interviewing person to get hold of the experience and knowledge behind their interviews. In our analysis as theoretical perspectives we used System theory, communication theory, attribution theory and the philosophy of Dialogue by Martin Buber.
Stabilitet och förändring i samband med en ERP-implementering : En fallstudie
Utvecklingen och användningen av ERP-system har blivit allt vanligare och trots att ett sådant system kan bidra med effektivitet kan implementeringen av ett sådant system innebära en omfattande organisatorisk förändring. Vid en förändring i form av införande av ny teknologi inverkar befintliga rutiner och institutioner på huruvida stabilitet kan upprätthållas. Stabilitet kan upprätthållas då nya regler går i linje med rådande rutiner eller vid närvaro av en lös koppling mellan dessa. Uppsatsens syfte är att genom en fallstudie undersöka om och isåfall hur stabilitet och förändring kan samverka vid implementering av ett ERP-system. Studien visar att detta är möjligt, dels tack vare att de anställda får vara delaktiga, att de inser förändringens huvudsakliga syfte samt att de nya reglerna går i linje med rådande rutiner och institutioner.
Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie
The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..
Systemtyper utanför ramen för både traditionell systemutveckling och e-infrastrukturutveckling : Finns de och hur bör de i så fall utvecklas?
Denna studie har som syfte att underso?ka om det finns en typ av system vars egenskaper liknar ba?de traditionella system och e-infrastrukturer utan att tillho?ra na?gon av dessa typer samt hur en designmodell skulle se ut fo?r denna typ av system. Detta system kallar vi gra?nsfallssystem.Fo?r att underso?ka om denna finns har traditionella system och e-infrastrukturer samt hur man utvecklar dessa typer av system analyserats. Detta fo?r att se ifall det existerar na?gon form av system som har egenskaper fra?n ba?da dessa ytterligheter och om det existerar sa?dana system hur man pa? ba?sta sa?tt ska utveckla dem.

The project enables mobile payment by text message (SMS). Most theory concerning the management of projects is developed for private companies.
Förväntningar: Hur de Påverkar Motivationen hos Nyanställda
This paper aims at shedding light on the effects of a broken psychological contract in terms of job satisfaction. In a qualitative field study, the author researches seven newly recruites employees about their expectations when starting their jobs at the rapidly growing, Swedish company Klarna. Using Herzbergs two-factor model of hygiene and motivation factors as well as modern motivation theory, i.e. self-determination theory, the study answers questions as to what makes a candidate choose a company and what factors motivates as well as demotivates the recruit at the job, in the onboarding phase. The result is an attempt to describe what makes a recruitment process successful..
Hur en okontrollerad expansion av IT-projekts omfattning undviks
Today there is an even higher demand on IT-projects success rate compared to a few years ago. IT-projects must be handled more efficiently and result in a more profitable investment. In order to make the handling of IT-projects more efficient and create profitability the developers must have a broad understanding of the IT-projects characteristics and which factors that affect the result of the projects. Changes within IT-projects are often carried out through the development of a system. Since this change is more common when it comes to IT-projects it is important to handle risk and change within these kinds of projects in order to prevent and avoid uncontrolled changes.
Borde Sverige gå från ett spelmonol till ett licenssystem gällande EMV lotterier? : En kostnadsnyttoanalys
The gambling industry goes from a national matter towards an international market. Since more and more members of EU does liberalise the gambling reforms and introduces a license system more participants will get an EU license for online gambling. With an EU license it is difficult for members of the EU to refuse a company to offer a gambling supply on the Internet if they don?t have an open license system. This paper tries to acknowledge the problem regarding the monopoly Sweden has today and calculate the effect if Sweden would move to a license system regarding online gambling by doing a cost benefit analysis.
Prestandaförändringen hos en bergvärmeanläggning efter fem års drifttid
The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.
OSE och Linux : En studie om prestanda
There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..
Hazel- Ett mjukvarusystem för automatisk och optimal schemaläggning
This report documents the development of a software system for automaticscheduling called Hazel. This system is comprised of a server where an automaticscheduler has been implemented, as well as a web and mobile applicationthat allows users to interact with the system. The scheduler hasbeen developed with the functional programming language Haskell and usesa SAT-solver.Manual scheduling has long been the bane of managers everywhere, asmatching the needs of the employer with those of the employee is often adifficult and time-consuming task. There already exists several automaticschedulers that attempt to solve this problem. The issue with said schedulersis that thay tend to be expensive, or developed to only fulfill the needsof a particular organisation.
