[pt] Este estudo investiga o tema das drogadicções a partir de um referencial psicanalítico. A droga é vista como um meio de intensa satisfação pulsional, que pode levar, pela drogadicção, a um certo isolamento e alheamento das determinações subjetivas. O autor parte de algumas proposições freudianas sobre a droga e as drogadicções para investigar as operações de constituição do sujeito em Lacan. Verifica, a partir daí, a importância da relação com a alteridade no processo contínuo de sustentação da atividade representativa inconsciente. Para o tratamento, propõe que o analista forneça uma atenção especial aos atos - passagem ao ato e acting-out - que surgem desde as entrevistas preliminares. Indica a presença, nestes casos, de uma operação de exclusão da atividade representativa, que poderá ser inicialmente retomada pela via dos atos que, por sua vez, podem servir para resgatar a função do sujeito do inconsciente. Inclui um caso clínico, onde se fez uso das concepções teóricas desenvolvidas. / [en] This study investigates the theme of drug addiction from a psychoanalytic referential. The drug is seen as a way of intense drive satisfaction, which may lead, through drug addiction, to a certain alienation and isolation from subjective determinations. Starting with some Freudian principles about the drug and the drug addictions, the author sets out to investigate the operations of subject constitution in Lacan. It is therefore ascertained the importance of the relation with the Other in the continuous process of sustaining the representative activity of the unconscious. For the treatment, it is proposed that the analyst pays particular attention to the acts - passage à l acte and acting-out - which become evident from the preliminary interviews. It is indicated the existence of an operation of exclusion of the representative activity. This representative activity may be initially resumed via the acts, which, in turn, may serve to recapture the function of the unconscious subject. A clinical case is included, in which the use of theoretical concepts developed is made.

The empirical literature on mergers, market power and collusion in differentiated markets has mainly focused on methods relying on output and/or panel data. In contrast to this literature we suggest a novel approach that allows for the detection of collusive behavior among a group of firms making use of information on the spatial structure of horizontally differentiated products. By estimating best response functions using a spatial econometrics approach, we focus on differences in the strategic interaction in pricing between different groups of firms as well as on differences in price levels. We apply our method to the market for ski lift tickets using a unique data set on ticket prices and detailed resort-specific characteristics covering all ski resorts in Austria.

The aim of this dissertation is to evaluate and compare the chosen integrated transport systems in the Czech Republic and based on findings submit a proposal to improvement. For this purpose are chosen the largest and the smarter transport sysstems in the Czech Republic, which are: - Integrated transport system of the Hradec Kralove region (IREDO) - Prague integrated transport system (PID) - Integrated transport system of the South Moravia (IDS JMK) Within the analysis is used the evaluation of the qulitative indicators, for example the number of the carriers, the number of tthe stations etc. This shows that these indicators haven?t got sufficient predictive value for the analysis and final evaluation, because some differences among the transport system. Therefore are the ratios included the analysis, which arw designed on the basis of the quantitative criterions recalculated for factors causing the significant differences of the transport systems. From the analysiss came out best the Integrated transport system in Prague (PID), because of the high freguency of the transport links, large fleet, reliable continuity of the transport links, and the positive evaluation of the range of distribution network, the number of vending machines, types of tickets and existence of the car lots P+R. The worst rated is Integrated transport system of Hradec Kralove region (IREDO), which was recomended to concenterate for the information sources and to attractive the system by these sources. Generally speaking the successful integrated transport systems are these which comply with conditions of the uniformity, intelligibility and clarity. Another important factor is the high frequency of the transport links, the continuity, availability of the bus stops and of course the quality passenger information.

More than ever, businesses heavily rely on IT service delivery to meet their current and frequently changing business requirements. Optimizing the quality of service delivery improves customer satisfaction and continues to be a critical driver for business growth. The routine maintenance procedure plays a key function in IT service management, which typically involves problem detection, determination and resolution for the service infrastructure. Many IT Service Providers adopt partial automation for incident diagnosis and resolution where the operation of the system administrators and automation operation are intertwined. Often the system administrators' roles are limited to helping triage tickets to the processing teams for problem resolving. The processing teams are responsible to perform a complex root cause analysis, providing the system statistics, event and ticket data. A large scale of system statistics, event and ticket data aggravate the burden of problem diagnosis on both the system administrators and the processing teams during routine maintenance procedures. Alleviating human efforts involved in IT service management dictates intelligent and efficient solutions to maximize the automation of routine maintenance procedures. Three research directions are identified and considered to be helpful for IT service management optimization: (1) Automatically determine problem categories according to the symptom description in a ticket; (2) Intelligently discover interesting temporal patterns from system events; (3) Instantly identify temporal dependencies among system performance statistics data. Provided with ticket, event, and system performance statistics data, the three directions can be effectively addressed with a data-driven solution. The quality of IT service delivery can be improved in an efficient and effective way. The dissertation addresses the research topics outlined above. Concretely, we design and develop data-driven solutions to help system administrators better manage the system and alleviate the human efforts involved in IT Service management, including (1) a knowledge guided hierarchical multi-label classification method for IT problem category determination based on both the symptom description in a ticket and the domain knowledge from the system administrators; (2) an efficient expectation maximization approach for temporal event pattern discovery based on a parametric model; (3) an online inference on time-varying temporal dependency discovery from large-scale time series data.
