Att mäta eller inte mäta : en studie om fo?rha?llandet mellan prestationsma?tning och kulturell styrning i mer eller mindre osa?kra omgivningar
Det finns i management control-litteraturen en efterfra?gan pa? studier som tar ett helhetsperspektiv pa? styrsystem (Management Control Systems, MCS) och som fo?rklarar hur dessa system bidrar till effektivitet hos organisationer. Utifra?n ett contingency-synsa?tt underso?ker vi i denna studie hur kulturell styrning och prestationsma?tning som delar av MCS, tillsammans med den kontextuella variabeln osa?kerhet i omgivningen, pa?verkar hur effektiva organisationer a?r. Vi antar en systemansats och o?nskar studera relationen mellan fler variabler, och da?rfo?r tilla?mpas en klusteranalys da?r datamaterialet delas in i grupper med liknande karakta?ristika.
Självreglering eller lagstiftning : inom informationssäkerhet
Sja?lvreglering inom olika marknader a?r inte na?gon ny ide?, utan har funnits under la?ng tid i Sverige och internationellt. Sja?lvreglering ga?r i korthet ut pa? att pa? frivillig grund skapa normer som pa? olika sa?tt sa?krar kvaliteten fo?r producerade varor och tja?nster. Det kan till exempel handla om etiska regelverk och rekommendationer fra?n branschorganisationer.

VoIP-system inom fo?retag blir mer vanligt. Sa?kerheten bo?r da? beaktas fo?r att undvika hot som riskerar konfidentialitet, integritet och tillga?nglighet. Denna rapport visar resultat fra?n tva? olika VoIP-systems sa?kerhet med hja?lp av praktiska penetrationstestscenarion i labbmiljo?.
Säkerhetsklassificering av IT-system på Fläkt Woods AB
This report presents a method for modelling a computer system from a security perspective. The questions that are going to be treated are:? What defines a secure system and how does the company relate to these factors?? What are the threats today based on hardware/software, human factors and company routines/policies?? What measures should be taken for the organisation to reach a higher level of security for their systems?? How do we develop a method for classification of security and what components should it contain?? What changes are reasonable and necessary with the respect to the company?s resources?The report has been done through interviews and analysis of existing systems on Fla?kt Woods AB. From analysis of material, the aspects judged relevant to the subject and to the company?s needs, have been compiled to a document.
Sakta men s?kert ? snabbt men (r?tts)os?kert? En r?ttsdogmatisk analys av balansen mellan r?ttss?kerhet och effektivitet i snabbare lagf?ring
Reformen Snabbare lagf?ring inf?rdes f?r att p?skynda r?ttsprocessen och effektivisera hanteringen av mindre allvarliga brott. Syftet var att minska tiden mellan brott och lagf?ring samt att effektivisera resursanv?ndningen i utredningsarbetet. Samtidigt har reformen m?tt kritik f?r att inskr?nka r?ttss?kerheten, s?rskilt n?r det g?ller den misst?nktes r?tt till f?rsvar och m?jligheten att ?verklaga.
Sjuksk?terskors upplevelser av patients?kerhet vid tolkanv?ndning inom v?rden En litteratur?versikt
Bakgrund: Sjuksk?terskors har en nyckelroll i v?rden och vikten av effektiv kommunikation
f?r att s?kerst?lla h?gkvalitativ omv?rdnad. Spr?kbarri?rer identifieras som hinder f?r
kommunikation och patients?kerhet, d?r anv?ndningen av tolkar kan vara en l?sning men ocks?
medf?ra utmaningar. Det ?r av avg?rande betydelse att s?kerst?lla korrekt information och
kommunikation f?r att minska risken f?r v?rdsskador och fr?mja patients?kerheten.
Dokumenthanteringssystem inom byggbranschen
One of the aims of this report has been to make an inventory of the building trade market to see which document handling systems that are available. The secondary aim was to document the users´ demands on the systems and other demands such as quality assurance. After this, the document handling systems Byggnet and Lotus Notes, which are rather complex systems, have been analysed. Finally a recommendation has been made. In the inventory of the marketthe internet has been used because it is there the latest information can be found.
Säkerhetstänkande integrerat i systemdesign via formaliserade metoder
Systems development methods mirror different organizational perspectives, and not all methods are formalised, but what they have in common is the purpose of structuring and supporting systems development processes. Which method would be the most suitable may be determined by the systems development context at hand, because every systems development context is unique. Information is a valuable asset in today?s organizations, and it needs to be protected against both internal and external security threats. In our essay we aspired to find and present suggestions as to how systems developers can include security in the very design based on formalised systems development methods to create systems that are better prepared to meet the security challenges of today.
Tillverkarnas syn på utvecklingen av väderskydd
How does the weather protection systems look like today, and how will they be developed in the future? These are questions that we have worked with during this project. At the start of our report there?s a summary of the leading weather protection manufacturers in Sweden. We have explained how these systems are constructed and how they work.
"Den som är satt i skuld är icke fri" : En studie om de svenska elnätsföretagens kapitalstrukturer
Title: Co-operative, prevent or complement? - An essay on the relationships between control systems. Authors: Kim Eriksson and Victoria KarlssonPurpose: The essay aims to describe the relations between control systems and how they related to each other, based on an operationalization of the control systems. Research question: What are the control systems relations to each other? With regards whether control systems co-operative, prevents and/or complement each other.Theoretical framework: The essays theoretical framework is based on Malmi and Browns (2008) description of five different control systems and control mechanisms associated with each control system.   Research methodology: The method was based on three different data collection methods. These methods were observations, documentation, and semi-structured interviews.Conclusions: It is concluded that the control systems has comprehensive relations. Control systems have more, than one, relation to each other..

Att vakta den digitala staten - En kvalitativ intervjustudie om svenska myndigheters strategi och upplevelser av ett f?r?ndrat cyberlandskap
Denna studie syftar till att skapa kunskap om hur svenska myndigheter upplever f?r?ndringar
i cyberhotbilden samt hur de arbetar med att f?rebygga, hantera och anpassa sina interna
s?kerhets?tg?rder i en f?r?nderlig omv?rldsbild.
Analysen utg?r fr?n tv? teoretiska perspektiv. Rutinaktivitetsteorin anv?nds f?r att f?rst?
myndigheter som kapabla v?ktare i den digitala milj?n och hur s?kerhets?tg?rder kan minska
tillg?ngligheten f?r motiverade angripare. Teorin om risksamh?llet anv?nds f?r att analysera
hur myndigheter agerar proaktivt i en kontext pr?glad av os?kerhet, d?r riskbed?mningar ofta
grundar sig p? framtida hot snarare ?n faktiska h?ndelser.

Energivinst vid hybridisering av hydrauliskt system
Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.
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..
