The goal of the thesis is creating marketing strategy of small intuitive driven family business. Small and medium sized entities where Sprint belongs, have defined marketing strategy rarely. Therefore marketing strategy and its implementation into the management is big competitive advantage. Theoretic part of the thesis includes strategic analysis of external and internal environment of the enterprise which is summarized by SWOT analysis. Marketing strategy based on strategic analysis conclusions is defined in several areas: main marketing goals, human resources, product portfolio, price, distribution and communication.

The aim of this thesis is to introduce the family of A5 algorithm which is used in data encryption and decryption in GSM phones. It is focused on real time cryptanalysis of the stream cipher A5/1. It describes in detail the known plaintext attack published by A. Biryukov, A. Shamir and D. Wagner. Both the attack and the cipher are implemented. The implementation proves that the preprocessing stage of the attack is very time consuming, but the actual attack can be carried out in real time on a single PC. Then the problem of finding a good statistical model for the process of generating tree of predecessors of internal states of A5/1 is studied. We present reasons why the singletype Galton-Watson process is not suitable for the problem and introduce a multitype Galton-Watson process and a macro process. The models are applied to the process of generating predecessors and their predictions are compared with experimental data.

<p>Upotrebom 50% etanola i superkritičnog ugljendioksida kao ekstragensa izvr&scaron;ena je ekstrakcija različitih vrsta pečuraka. Nakon određivanja prinosa suvih ekstrakata, u njima su određeni: sadržaj ukupnih fenola i ukupnih flavonoida, sadržaj makro- i mikro-elemenata, sadržaj adenozina, kao i sadržaj karakterističnih komponenata pistilarina i variegetične kiseline. Najveći sadržaj ukupnih fenolnih jedinjenja određen je u suvom ekstraktu pečurke <em>C. pistillaris</em>, najveći sadržaj ukupnih flavonoida u ekstraktu <em>D. confragosa</em>, a najvi&scaron;e esencijalnog cinka i selena sadrži suvi ekstrakt pečurke <em>B. edulis</em>. U odnosu na ostale suve ekstrakte ekstrakt pečurke <em>L. saccatum</em> sadrži nekoliko puta veću količinu adenozina. Antioksidativno delovanje suvih ekstrakata analizirano je primenom spektrofotometrijskih i EPR metode. Ekstrakti <em>C. pistillaris, B. edulis </em>i <em>A. mellea</em> pokazali su se kao najefikasniji skevindžeri najopasnije slobodnoradikalske vrste hidroksil radikala, dok se efikasnim u prevenciji lipidne peroksidacije mogu smatrati ekstrakti <em>B. edulis, A. mellea </em>i<em> L. saccatum</em>. Nakon određivanja prinosa supekritičnih ekstrakata ispitivanih pečuraka, u njima je analiziran sastav masnih kiselina i detektovana jedinjenja sterolnog tipa. U ispitivanim ekstraktima dominantna je nezasićena linoleinska kiselina, a značajan je udeo i oleinske nezasićene masne kiseline. Dominantno jedinjenje sterolne strukture u gotovo svim ekstraktima je ergosterol. Ispitan je uticaj superkritičnih ekstrakata pečuraka na fluidnost membrane eritrocita i na osnovu dobijenih rezultata zaključeno da bi značajnu ulogu u antihipertenzivnoj ishrani mogle imati pečurke <em>A. mellea </em>i<em> M. procera</em>.</p> / <p>Using 50% ethanol and supercritical carbon dioxide different mushroom extracts were prepared.

Allt fler socialarbetare väljer idag att åka ut i världen för att arbeta med olika projekt. Det internationella perspektivet är av stor relevans för socialt arbete då globaliseringen av världen gör länder allt mer beroende av varandra och sociala problem kräver internationella lösningar. Kunskaper om hur man arbetar med sociala problem på en strukturell nivå är mycket viktigt inom det internationella fältet för att uppnå hållbara förändringar. Syftet med uppsatsen har varit att bidra med en förståelse för hur socialarbetare arbetar med förändring utifrån ett strukturellt perspektiv inom socialt arbete i utvecklingsländer. Det vi frågat oss är vilka möjligheter som finns, vilka utmaningar och hinder som kan uppstå samt vilka metoder och kunskaper som är viktiga vid socialt förändringsarbete i utvecklingsländer då man arbetar utifrån ett strukturellt perspektiv. För att svara på uppsatsens syfte och frågeställningar har vi valt att genomföra fem kvalitativa intervjuer med socialarbetare med erfarenhet av strukturellt socialt arbete i utvecklingsländer. Intervjumaterialet har bearbetats och analyserats utifrån: Teorier kring Social Mobilisering, Systemteori och Maktteorier samt utifrån tidigare forskning. Intervjumaterialet visar på att det finns stora möjligheter att uppnå förändring på strukturell nivå men att det kan uppstå utmaningar och hinder på vägen. Makt och hierarkier är exempel på sådana hinder. Viktiga metoder för att öka dessa möjligheter är exempelvis att arbeta på flera nivåer i samhället och att arbeta tillsammans med de människor som hjälpen åsyftar. Kunskaper om helhetsperspektiv som inkluderar individ, grupp och samhälle är av betydande vikt för socialarbetaren i det strukturella förändringsarbetet i utvecklingsländer och vikten av att vara lyhörd, respektfull och ödmjuk lyfts fram.

Readjusting Historical Credit Ratings using Ordered Logistic Re-gression and Principal Component Analysis The introduction of the Basel II Accord as a regulatory document for creditrisk presented new concepts of credit risk management and credit risk mea-surements, such as enabling international banks to use internal estimates ofprobability of default (PD), exposure at default (EAD) and loss given default(LGD). These three measurements is the foundation of the regulatory capitalcalculations and are all in turn based on the bank’s internal credit ratings. Ithas hence been of increasing importance to build sound credit rating modelsthat possess the capability to provide accurate measurements of the credit riskof borrowers. These statistical models are usually based on empirical data andthe goodness-of-fit of the model is mainly depending on the quality and sta-tistical significance of the data. Therefore, one of the most important aspectsof credit rating modeling is to have a sufficient number of observations to bestatistically reliable, making the success of a rating model heavily dependenton the data collection and development state.The main purpose of this project is to, in a simple but efficient way, createa longer time series of homogeneous data by readjusting the historical creditrating data of one of Svenska Handelsbanken AB’s credit portfolios. Thisreadjustment is done by developing ordered logistic regression models thatare using independent variables consisting of macro economic data in separateways. One model uses macro economic variables compiled into principal com-ponents, generated through a Principal Component Analysis while all othermodels uses the same macro economic variables separately in different com-binations. The models will be tested to evaluate their ability to readjust theportfolio as well as their predictive capabilities. / Justering av historiska kreditbetyg med hjälp av ordinal logistiskregression och principialkomponentsanalys När Basel II implementerades introducerades även nya riktlinjer för finan-siella instituts riskhantering och beräkning av kreditrisk, så som möjlighetenför banker att använda interna beräkningar av Probability of Default (PD),Exposure at Default (EAD) och Loss Given Default (LGD), som tillsammansgrundar sig i varje låntagares sannoliket för fallissemang. Dessa tre mått ut-gör grunden för beräkningen av de kapitaltäckningskrav som banker förväntasuppfylla och baseras i sin tur på bankernas interna kreditratingsystem. Detär därmed av stor vikt för banker att bygga stabila kreditratingmodeller medkapacitet att generera pålitliga beräkningar av motparternas kreditrisk. Dessamodeller är vanligtvis baserade på empirisk data och modellens goodness-of-fit,eller passning till datat, beror till stor del på kvalitén och den statistiska sig-nifikansen hos det data som står till förfogande. Därför är en av de viktigasteaspekterna för kreditratingsmodeller att ha tillräckligt många observationeratt träna modellen på, vilket gör modellens utvecklingsskede samt mängdendata avgörande för modellens framgång.Huvudsyftet med detta projekt är att, på ett enkelt och effektivt sätt, skapaen längre, homogen tidsserie genom att justera historisk kreditratingdata i enportfölj med företagslån tillhandahållen av Svenska Handelsbanken AB. Jus-teringen görs genom att utveckla olika ordinala logistiska regressionsmodellermed beroende variabler bestående av makroekonomiska variabler, på olikasätt. En av modellerna använder makroekonomiska variabler i form av princi-palkomponenter skapade med hjälp av en principialkomponentsanalys, medande andra modelelrna använder de makroekonomiska variablerna enskilt i olikakombinationer. Modellerna testas för att utvärdera både deras förmåga attjustera portföljens historiska kreditratings samt för att göra prediktioner.

No. of bitstreams: 0 Previous issue date: 2003-03-17T00:00:00Z / Este estudo teve por objetivo identificar e descrever o processo de estratégia de duas grandes organizações do ramo varejista pela ótica da estratégia deliberada, destacando as principais características, modelos e ferramentas teóricas que se aplicam aos casos empíricos. Assim, realizou-se uma pesquisa qualitativa, essencialmente descritiva, com abordagem de estudo de caso junto ao Makro Atacadista e a Wal-Mart. Observou-se que o processo de estratégia do Makro caracteriza-se por ser formal, consciente, sistemático, contínuo e organizado e por seguir uma sequência bem definida de etapas pré-programadas. Os agentes estratégicos são os Diretores da empresa e a estratégia é tornada explícita através de planos e programas. Na Wal-Mart, a formulação da estratégia passa por um processo de concepção, no qual o líder (Presidente da empresa) tem papel fundamental. O modelo é simples e informal e as estratégias são implementadas através de um processo de institucionalização. Nos dois casos, a formulação da estratégia precede a implementação, sendo que a formulação é responsabilidade do Presidente e Diretores e a implementação é executada por seus subordinados. Não se utilizam nos casos as ferramentas analíticas propostas por alguns teóricos da estratégia deliberada e a análise da concorrência é realizada de modo intuitivo. Além disso, não se verifica um modelo de estratégia padrão para as empresas estudadas. Cada qual impõe as suas especificidades organizacionais ao processo de estratégia. Observou-se: que o processo deliberado gera integração e unidade entre os funcionários das empresas, pois todos se alinham num foco comum. Constatou-se ainda a importância do sistema tecnológico das empresas no processo de estratégia, principalmente no que se refere ao controle estratégico. Por fim, o estudo realizado pela ótica da estratégia deliberada demonstrou-se importante, pois, ao contrário do que alguns teóricos, em especial Mintzberg, argumentam, os processos de estratégia empíricos provaram-se essencialmente deliberados. / This study had as purpose to identify and describe the strategy process of two major retailers from the point of view of deliberate strategy, pointing out the main characteristics, models and theoretical tools applicable to empirical cases. .Thus, a qualitative, essentially descriptive research was performed, approaching a case study with Makro Atacadista and Wal-Mart. It was observed that Makro's strategy process is distinguished for being formal, conscious, systematic, continuous and organized, and following a well-defined sequence of predetermined stages. The strategic agents are the company's Directors and the strategy is made explicit through plans and programs. At WalMart, strategy formulation undergoes a conception process where the leader (President of the company) plays a criticai role. The model is simple and informal and the strategies are implemented through an institutionalization processo In both cases, strategy formulation precedes implementation, where the President and the Directors are responsible for its formulation while their subordinates perform its implementation. The analytic tools proposed by some theorists of deliberate strategy are not used in these cases and the competitors' analysis is made based on intuition. Besides, there is no standard strategy model for the surveyed companies. Each of them imposes its own organizational peculiarities on the strategy processo It was observed that the deliberate process generates integration and unity among the companies' employees, since they are ali aligned with a common focus. It was verified further that the companies' technological system is very important for their strategy processes, particularly as regards the strategic control. Finally, the study made from the point of view of deliberate strategy showed up to be extremely important, since, as otherwise argued by some theorists, particularly Mintzberg, empirical strategy processes proved to be essentially deliberate.

Diploma thesis analyses the macro practice in the Czech social work. It defines macro practical concept and its relationship to social policy and community social work by analysing the Czech and foreign specialized publications. It defines the key knowledge, skills and abilities which macro practicioner should manage. It emphasizes the macro scope towards the political representation. Macro practical methods are presented too. Diploma thesis defines two main principles - networking and evidence based practice. At first, macro practicioner is the creator of professional's networks or social services network. Secondly, in the evidence based practice macro practicioner is obligated to manage his decision making process on the base of the best and the most recent scientific researches. It all concludes the macro practice framework, which leads to the efective work with social excluded people. Macro practice is viewed as the approach, which helps clients, communities, regions and target groups in the implementation of their civil right, when it uses the enpowerment techniques. According to the international perspective, the status of the actual Czech macro practice is vieved as unconsolted. Therefore, author proposes the development of the social work education on the bachelor and master degrese...
