Making the work in the public sector more efficient is something that has been seen as necessary during the later years. One way to do this on municipal level has been to apply solutions former used mostly by private companies. The organisational parts have also been adjusted to existing conditions in this work of change. For example more and more municipalities have come to use the purchaser-supplier model since the beginning of the 1990's. Norrköping, Linköping and Motala have been chosen in this essay for a closer study of the effects of the changes of the 90's, from an efficiency point of view. Even the process whereby the changes have been performed has been studied. The result that is being presented is that the purchaser-supplier model in many ways has contributed to an increased consciousness about the existing problems in the work and organisation in the municipalities. At the same time there is critics about the way the model is being used, and about the fact that the application isn't always adjusted to the existing reality.

The aim of the study has been to gain an increased understanding of the sense of participation and influence that the enrolled nurses, working with home-help services within the purchaser – provider model, feel and how this participation and influence affect them. Five enrolled nurses in three of Stockholm's districts related their experiences of participation and influence at work in the qualitative interviews that were conducted. The result was then analyzed with the help of two theories, Karasek's and Theorell´s Demand- Control Model and Antonovsky's theory regarding ”a Sense of Coherence (SOC)”. The analyzes show that the enrolled nurses have a low sense of participation and influence regarding decisions relating to their work situation. Decisions that affect the enrolled nurses are made by politicians, directors, and care managers of the city districts (biståndshandläggare). On the other hand, the enrolled nurses felt strong support from their peers at work. They could socialize and discuss issues with them. The analyzes show that without their peer support, they would have a lower sense of participation and influence. Furthermore the analyzes show that the interview subjects possess knowledge and competence that they are unable to make use of in their work.

Each product is available on a subset of markets and its unit cost depends on the market where it is available. The objective is to buy all the products, departing and returning to a domicile, at the least possible cost defined as the summation of the weights of the edges in the tour and the cost paid to acquire the products. A Transgenetic Algorithm, an evolutionary algorithm with basis on endosymbiosis, is applied to the Capacited and Uncapacited versions of this problem. Evolution in Transgenetic Algorithms is simulated with the interaction and information sharing between populations of individuals from distinct species. The computational results show that this is a very effective approach for the TPP regarding solution quality and runtime.

Since the end of the 1980s, the introduction of market mechanisms in the public sector has been a dominant feature in Sweden. The same is true for the social services in several municipalities, where business style behaviour and organisation, and competition have become salient features of market-oriented social services. The aim of the study is to describe and analyse: the structural conditions for market oriented personal social services; how social workers pursue client centred work in market oriented personal social services; the consequences of this market orientation on the personal social services. The empirical study is a case study of the personal social services in the municipality of Linköping. The purchaser-provider model in Linköping is one of the most advanced and discussed in Sweden. The research comprises a quantitative pilot study and a qualitative main study. The main study is based on twenty semi-structured interviews with experienced social workers and their immediate superiors. The analysis of the interviews reveals that the personal social services are only achieving to a lesser extent the ends that a quasi-market, theoretically, should achieve. The conditions that have to be satisfied to achieve the ends of the quasi-market are only partly met. Bureaucratic control is one important reason why the personal social services are imperfect as a quasi- market. The re-organisation has resulted in a number of, to some extent, positive consequences. The re-organisation has, however, also resulted in some negative consequences. In the thesis these are categorised in terms of fragmentation, antagonism and obscurity. A linguistic change, in market oriented personal social services, appears to have influenced social workers to think and act differently in relation to their work. The most important conclusion drawn from the study is that the market oriented personal social services partly function as a responsive quasi-market for strong, rational and well- informed clients. However, in relation to the most vulnerable, it is failing in many respects. / digitalisering@umu

Private enforcement, which primarily represents individuals&rsquo / right to claim damage arisen from violations of competition law, supplements public enforcement and ensures indemnification of individual loss. However, private enforcement of competition law has fallen behind public law enforcement in laws presented in this study, other than those enforced in the USA. Realizing this fact, European Commission, has recently focused on the enhancement and facilitation of private enforcement in the Community competition law. The lagging behind of private enforcement mainly sources from the cultural and traditional differences in the understanding of liability law between Anglo Saxon Law and Continental Law. Anglo Saxon law tradition is inclined to leave the matter to individual action, whereas Continental Law is in more favor of strengthening regulatory mechanisms. More specific obstacles to the improvement of private enforcement are, yet not exhaustively, indefiniteness of legal basis of claims, involvement of complex economic analysis while stating the case, courts&rsquo / lack of technical knowledge, indefinite relationship between judiciary and competition authorities, problems in proving damage and causality, absence of facilitating procedural mechanisms such as class actions, treble damage and discovery rights. In the Community law context it is also highly probable to encounter peculiar problems arisen from co-existence of different national laws. Additionally, implementation of the Community competition law by national authorities may also lead to the weakening of the Single Market objective. Through this study, we will present probable solutions by depicting all these problems.

(Geo)demographic factors of consumers' behaviour Abstract The master's thesis deals with issues of consumer behavior in its theoretical plane. In order to empirically analyze behavior of consumers on the demand of housing, within the limits of population development of the Slovak Republic between the years 1990 and 2060. The objective of the analysis is the construction of housing demand query functions in the Slovak Republic, which indicates the trends of housing demand. Model translates demographic changes in the population behavior in quantitative and structural changes of the housing demand. The result is that, despite the expression of uncertainty in the development of behavioral population has forecast housing demand for the high rate of inertia. The latter starting from the stability of the age structure of the population. We are assuming that the period of the next sixty years will be characterized by changes in trends in the development of the population of a continuously aging population. What was negative and reflected in the curve of housing demand. Keywords: consumer, purchaser, demographic changes, population forcast, demand forcast, real estate, housing demand

This dissertation work is focused on issues related to a purchasing process in business subjects. It examines issues related to an evaluation of suppliers for a particular order. It also deals with issues within supplier-purchaser relationship, its creation and management through the SCM - Supply Chain Management. The topic of this thesis is very progressive as the selection and the evaluation of the suppliers is a very important factor in the terms of purchase and purchase expenses. A good management of the supplier-purchaser relationship can save expenses to business subjects. The elaboration of this dissertation thesis used not just theoretical findings acquired from the Czech and international literature, but also findings from surveys. The primary survey was carried out through the quantitative research, in particular research questionnaires. The findings from the primary survey were evaluated through the application Microsoft Excel and UNISTAT ® Statistical Package Version 5.6.06 Light. The acquired results were used to define the most important factors, which affect an evaluation of suppliers as well as an evaluation of the SCM in companies and data about purchases in companies. In addition the findings from the research questionnaires helped to evaluate the appointed hypothesis of the dissertation thesis. A partial outcome of the dissertation thesis is the proposal of the methodology of the evaluation of new and current suppliers including the weighting of individual evaluation parameters. For a common suppliers’ evaluation, an evaluation frequency is set by the importance of supplied material. Additionally, it methodologically describes how to evaluate supplier in time for day-to-day supply and for one-off supply. An additional partial outcome is the proposal of the methodology for an evaluation of a level of the SCM. The conclusion of the dissertation thesis is dedicated to the summary of findings, discussion of preconditions for implementation of the proposed methodology to real situations and possibilities of an additional scientist work in appropriately related subjects.

Many people still confused and misunderstand the differences between auction types: In fact, we have only two major types of auctions which are the forward auction and Reverse auction[22]. In a forward auction a single seller offers an item for sale with many competitive buyers driving the price upward: In a Reverse Auction, a single buyer wants to purchase a service or an item from many sellers, they drive the price downward: There are many differences between these type of auction: Including the progress of the auctions; winner selection criterion and other factors: The Reverse Auction nowadays is one of the most preferred types of online auctions: It gains popularity rapidly because of representing the buyers' side and helps him to drive prices down in contrary with the forward auction or traditional auction. The aim of this study is to identify the most common types of the Reverse auctions and compare them to one another to determine when should be used by a buyer and propose the most efficient implementation model for some types: The results of this study are: achieve a written report and a small demonstrator model on how to implement English Auction and Second-Sealed bid Auction.

Cette thèse a pour objet l'obligation de sécurité en matière la responsabilité contractuelle à la lumière du droit français et du droit libyen. La recherche tend à répondre aux questions suivantes : Qu'entend-on par sécurité des produits médicaux ? Sur quel fondement juridique peut-on justifier cette obligation ? Quelles sont les difficultés d'application de cette obligation pour traiter les problèmes de produits de santé ? C'est quoi le produits de santé ? Et Le droit de la responsabilité civile libyen est-il parfaitement adapté à la protection de la victime des produits de santé comme dans le droit de la responsabilité français ? Ce questionnement a conduit l'auteur à développer une analyse approfondie de l'obligation de sécurité en manière de la responsabilité contractuelle et le droit de la santé français et libyen. Dans la première partie de la thèse, on constate que la notion d'obligation de sécurité, y compris en matière de la responsabilité contractuelle, a connu une évolution majeure par rapport à l'époque précédant. En fait, l'apparition de la notion d'obligation de sécurité est ancienne puisqu'elle a été créée en France le 21 novembre 1911 à l'occasion du contrat de transport. Elle peut être définie comme « l'obligation de veiller à la sécurité d'une personne ou d'un bien, qui peut être une obligation de résultat ou de moyen ». Certains codes du monde proche-oriental ont adopté la résolution que la Cour de cassation française a prise en 1911 dans le domaine du transport de personnes, comme l'Egypte et le Liban. En 1956, la Cour d'Appel à Alexandrie a conformé l'obligation de sécurité dans le domaine du transport de personnes / This thesis focuses on the safety obligation regarding contractual liability in the light of French law and Libyan law. Research tends to answer the following questions: What is safety of medical products? On what legal basis can we justify that obligation? What are the difficulties in applying this requirement to address issues of health products? What is the health products? The law and civil liability Libya is it perfectly suited to the protection of the victim of health products as in the French liability law? This questioning has led the author to develop a thorough analysis of the safety obligation by way of contractual liability and health law French and Libyan. In the first part of the thesis, we see that the notion of bond security, including with respect to contractual liability, has experienced a major change from the time before. In fact, the emergence of the concept of safety obligation is old since it was founded in France 21 November 1911 at the contract of carriage. It can be defined as "the obligation to ensure the safety of any person or property which may be an obligation of result or means." Some codes of Near Eastern world have adopted the resolution that the French Supreme Court has taken in 1911 in the transportation of persons, such as Egypt and Lebanon. In 1956, the Appeal Court in Alexandria has complied with the requirement of safety in the transportation of persons. Similarly, in Lebanon in the Code of Obligations and Contracts provides in Article 688 that the contract of carriage of persons is the responsibility of the carrier's obligation to lead the traveler, unharmed, to the destination

The Diploma thesis ,Selected aspects of the retail supplier-purchaser relations' defines British grocery retailing. It presents government bodies which regulate retail industry and important independent not-for-profit organizations which have a strong influence on the market situation. It introduces the reader into legislation which regulates supplier-purchaser relations, particularly the Supermarket Code of Practice and its revised version the Groceries Supply Code of Practice. The analytical part examines the British market at the macroeconomical level, outlines the grocery retailing structure, describes the supply chain, customer behaviour, points out certain pricing and product policy trends and presents subjects which are bonded by the provisions set out in the Groceries Supply Code of Practice. The findings on local market competition and barriers which prevent the entry by a competitor are of a high significance as well. Despite the introduction of legal regulation the supplier-purchaser relations remain unequal and unfair. The thesis proposes a forecast of possible future grocery market development in the United Kingdom.
