The first chapter portrays the historical trajectory of the University of São Paulo and its Superintendence of Social Service, as well the debate about student assistance regarding the feasibility of free higher education as a human right. The second chapter presents a reflection on the changes caused by productive restructuration in the work progress. Finally, the third chapter analyzes the consequences of service system informatization, besides go on with the analysis of intensification and precarization process of the Social Workers work. The conclusion of our analysis suggests that we are facing a change that uses science and technology in service of big capital, intensifying and precarizing the life and work conditions, which cause physical and mental tiredness. Thus Social Workers as salaried public employee experience the same deleterious effect that experiences the private sector employees. Under these circumstances, we can say that financial capital, and its accumulation strategy, there isn t borders, because it invades as the private sphere as the public sphere, which suggests the need of further reflection on how to resist and to face the dismantling of universal rights / Este estudo teve como objetivos problematizar e aprofundar a reflexão sobre os fenômenos contemporâneos da intensificação, precarização e informatização dos processos de trabalho no cotidiano das assistentes sociais da SAS-USP. O primeiro capítulo retrata a trajetória histórica da Universidade de São Paulo e da Superintendência de Assistência Social, bem como traz à cena do debate a assistência estudantil na perspectiva da viabilização do direito ao ensino superior público e de qualidade. Já no segundo, serão aprofundadas as reflexões sobre as mudanças acarretadas pela reestruturação produtiva nos processos de trabalho. E, finalmente, no terceiro, serão analisados os reflexos promovidos pela informatização do sistema de atendimento, além de prosseguir com a análise dos impactos do processo de intensificação e precarização do trabalho das Assistentes Sociais. Na análise empreendida, conclui-se que estamos diante de uma avalanche de mudanças que utiliza a ciência e a tecnologia a favor do grande capital, intensificando e precarizando as condições de vida e de trabalho, o que provoca o desgaste físico e mental das assistentes sociais, as quais, na condição de trabalhadoras assalariadas, funcionárias públicas, experimentam os mesmos efeitos deletérios vivenciados pelos trabalhadores da iniciativa privada. Tal fato indica que o capital financeiro, em suas estratégias de acumulação, não tem fronteiras, pois invade tanto a esfera privada quanto a pública, o que aponta para a necessidade de se continuar a reflexão e a busca por estratégias de resistência e enfrentamento diante de tamanho desmonte dos direitos universais

The experiments were conducted at the Seed Laboratory of the Department of Forest Sciences and Seed Analysis Laboratory of the Department of Agriculture of the Federal University of Lavras, in Lavras-MG. The seeds were acquired by the company ?Sementes Cai?ara?, which were collected in arrays located in the municipality of Pen?polis-SP, in December 2014. After acquired and processed, the lot of seed was characterized by the purity tests, humidity, germination and thousand seed weight. The three main equipment used in the classification, evaluation and separation of the seeds were the equipment mini-SAS, x-ray and blower seed type General. In the X-ray test the seeds were classified according to the internal morphology displayed in the radiographic images, are classified as full seeds, empty or malformed. The seed samples identified by X-ray analysis were taken to germinate, each rank four replicates of 50 seeds. The full, empty and malformed seeds were evaluated externally by the mini-SAS equipment, through the characteristics: dominant color, area, maximum diameter, minimum diameter ratio maximum/minimum diameter and circumference. Each seed group consisted of four replications of 50 seeds. Other equipment used was the seed blower unit, which separated the seeds for the regulation of six different openings, with each of them a light fraction and one heavy. Evaluations were made by weighing the seeds remaining in the blower (heavy fraction) and the number of full seeds in this same fraction made by ray analysis X. Later germination tests were carried out consisting of four repetitions of 50 seeds. Regarding the germination study, the experiment was conducted in thermogradient table at temperatures of 15?C, 20?C, 25?C, 30?C, 35?C and 40?C with supplying constant light, each treatment consisting of four replications of 50 seeds. They were evaluated root issue, normal and abnormal seedlings, hard seeds and dead, in addition to IVG values, T50 and U75-25 to root issue, normal seedling. In determining the imbibition curve germination were tested under conditions of 30?C with constant light and 20-30?C (12h dark, 12h light). The curves were drawn from two replicates of 0,05g seed, the same being weighed in analytical balance for every three hours. After analyzing the data, it was concluded that the use together of seeds and ray blower devices are effective for evaluation and determination of the physical quality of the seeds M. polymorphum. Seed blower in regulating the opening 5 resulted in the better quality of the lot, with the largest number of full seeds. The external parameters assessed by the mini-SAS equipment were not able to qualitatively evaluate the seeds of M. polymorphum, not recommended its use to characterize them. In the germination of study at different temperatures, the best average values of the evaluated criteria resulted in 30?C temperature. In determining the curve imbibition, the seed germination phase pattern presented, and the root emission resulting in a smaller time interval at a temperature of 30?C with constant light, as evidenced from the imbibition phase III / O presente cap?tulo teve por finalidade analisar as propriedades f?sicas e fisiol?gicas das sementes de Moquiniastrum polymorphum por meio dos equipamentos raios X, mini-SAS e soprador de sementes, al?m de avaliar a germina??o em diferentes temperaturas e gerar a curva de embebi??o da esp?cie. Os experimentos foram conduzidos no Laborat?rio de Sementes do Departamento de Ci?ncias Florestais e no Laborat?rio de An?lise de Sementes do Departamento de Agricultura da Universidade Federal de Lavras, na cidade de Lavras- MG. As sementes foram adquiridas pela empresa Sementes Cai?ara, as quais foram coletadas em matrizes localizadas no munic?pio de Pen?polis-SP, em dezembro de 2014. Ap?s adquirido e beneficiado, o lote de semente foi caracterizado por meio dos testes de pureza, umidade, germina??o e peso de mil sementes. Os tr?s principais equipamentos utilizados na classifica??o, avalia??o e separa??o das sementes foram os equipamento de raios X, mini- SAS e soprador de sementes tipo General. No teste de raios X as sementes foram classificadas de acordo com a morfologia interna visualizada nas imagens radiogr?ficas, sendo classificadas como sementes cheias, vazias ou mal formadas. As amostras de sementes identificadas pela an?lise de raios X foram levadas para germinar, sendo cada classifica??o composto por quatro repeti??es de 50 sementes. As sementes cheias, vazias e mal formadas foram avaliadas externamente pelo equipamento mini-SAS, por meio das caracter?sticas cor dominante, ?rea, di?metro m?ximo, di?metro m?nimo, rela??o di?metro m?ximo/m?nimo e per?metro. Cada grupo de sementes foi composto por quatro repeti??es de 50 sementes. Outro equipamento utilizado foi o aparelho de soprador de sementes, o qual separou as sementes pela regulagem de seis aberturas diferentes, apresentando em cada uma delas uma fra??o leve e outra pesada. As avalia??es foram feitas pesando as sementes que permaneceram no soprador (fra??o pesada) e sobre a quantidade de sementes cheias nesta mesma fra??o feita pela an?lises de raios X. Posteriormente foram realizados testes de germina??o compostos por quatro repeti??es de 50 sementes. Em rela??o ao estudo da germina??o, o experimento foi conduzido em mesa termogradiente nas temperaturas de 15?C, 20?C, 25?C, 30?C, 35?C e 40?C com fornecimento de luz constante, sendo cada tratamento composto por quatro repeti??es de 50 sementes. Foram avaliados emiss?o radicular, pl?ntula normal e anormal, sementes mortas e duras, al?m dos valores IVG, T50 e U75-25 para emiss?o radicular, pl?ntula normal. Na determina??o da curva de embebi??o foram testadas germina??es nas condi??es de 30?C com luz constante e 20-30?C (12h ao escuro, 12h em luz). As curvas foram elaboradas a partir de duas repeti??es de 0,05g de sementes, sendo as mesmas pesadas em balan?a anal?tica durante intervalos de tr?s horas. Ap?s a an?lise dos dados, concluiu-se que a utiliza??o em conjunto dos equipamentos de soprador de sementes e raios X s?o eficientes para avalia??o e determina??o da qualidade f?sica das sementes de M. polymorphum. O soprador de sementes na regulagem da abertura 5 resultou a melhor qualidade do lote, apresentando o maior n?mero de sementes cheias. Os par?metros externos avaliados pelo equipamento mini-SAS n?o foram capazes de avaliar qualitativamente as sementes de M. polymorphum, n?o sendo recomendado seu uso para a caracteriza??o das mesmas. No estudo da germina??o em diferentes temperaturas, os melhores valores m?dios dos crit?rios avaliados resultou na temperatura de 30?C. Na determina??o da curva de embebi??o, a germina??o das sementes apresentou padr?o trif?sico, sendo a emiss?o radicular em menor intervalo de tempo resultante na temperatura de 30?C com luz constante, evidenciado a partir da fase III de embebi??o. .

Une échelle de qualité de vie doit vérifier différentes propriétés. L'unidimensionnalité est aujourd'hui communément admise : une échelle doit mesurer un concept unique. La simplicité d'utilisation de l'instrument de mesure est, elle aussi, importante. A ce titre le Rasch est intéressant puisque ce modèle est sous-jacent à toute notion de score non pondéré. Ce travail s'inscrit donc dans le cadre de la sélection d'items vérifiant un modèle de Rasch. Un modèle multidimensionnel est proposé : le modèle marginalement exhaustif de Rasch (MMSRM), pour lequel, chaque dimension garde les propriétés psychométriques du modèle de Rasch. Trois méthodes basées sur l'adéquation d'un tel modèle aux données sont proposées, et comparées par simulations à des procédures existantes. Une seconde partie du travail concerne le développement de programmes pour utiliser des modèles psychométriques sous deux logiciels statistiques : SAS et Stata.

The development of low-frequency SONAR systems, using a network of autonomous systems in unmanned vehicles, provides a practical means for bistatic measurements (i.e. when the source and receiver are widely separated, thus allowing multiple viewpoints of a target). Furthermore, time-frequency analysis, in particular Wigner-Ville analysis, takes advantage of the evolution of the time dependent echo spectrum to differentiate a man-made target (e.g. an elastic spherical shell, or cylinder) from a natural one of the similar shape (e.g. a rock). Indeed, key energetic features of man-made objects can aid in identification and classification in the presence of clutter and noise. For example, in a fluid-loaded thin spherical shell, an energetic feature is the mid-frequency enhancement echoes (MFE) that result from antisymmetric Lamb waves propagating around the circumference of the shell, which have been shown to be an acoustic feature useful in this pursuit. This research investigates the enhancement and benefits of bistatic measurements using the Wigner-Ville analysis along with acoustic imaging methods. Additionally, the advantage of joint space-time-frequency coherent processing is investigated for optimal array processing to enhance the detection of non-stationary signals across an array. The proposed methodology is tested using both numerical simulations and experimental data for spherical shells and solid cylinders. This research was conducted as part of the Shallow Water Autonomous Mine Sensing Initiative (SWAMSI) sponsored by ONR.

This thesis is based on a case study of an airline’s (Scandinavian Airlines (SAS)) customers’ views on self-service technologies for check-in; mobile check-in, internet check-in, and machine (kiosk) check-in. The first aim of the paper was to find sources of satisfaction and dissatisfaction in the airline industry. A number of critical incidents leading to satisfactory and dissatisfactory experiences have been categorized by using the critical incident technique method based on customers’ recalls of past events. Main sources of satisfaction were the SSTs ability to provide a more efficient service by time savings, avoiding queues and by providing increased customer control. Main sources of dissatisfaction were related to technology failure such as malfunctioning machines, technical design problems and service design problems due to unclear role clarity among customers caused by lack of information and trust in own abilities. Second aim of the study was to identify a number of variables affecting SST channel selection. Qualitative interviews revealed following main variables affecting channel choice: accessibility, awareness, lack of trust, and perceived channel efficiency. Findings have been discussed from the perspective of models used in present research such as the consumer readiness model and trusting intentions model so that future researchers can identify and use valid models for understanding SST channel adoption and satisfaction drivers in the flight industry. Hands on managerial implications are provided in the closing part of the paper. Originality: The thesis show industry specific satisfaction and dissatisfaction causes that differ from previous research. Second contribution is the development and classification of factors in groups that influence the SST channel choice for check-in at airports. Finally the paper shows that none of the current models for use intention can independently be used to fully explain choice of channel.

The class of models which is studied in this paper, multi-unit longitudinal models, combines both the cross-sectional and the longitudinal aspects of observations. Many empirical investigations involve the analysis of data structures that are both cross-sectional (observations are taken on several units at a specific time period or at a specific location) and longitudinal (observations on the same unit are taken over time or space). Multi-unit longitudinal data structures arise in economics and business where panels of subjects are studied over time, biostatistics where groups of patients on different treatments are observed over time, and in situations where data are taken over time and space. Modelling issues in multi-unit longitudinal models with random coefficients and patterned correlation structure are illustrated in the context of two data sets. The first data set deals with short time series data on annual death rates and alcohol consumption for twenty-five European countries. The second data set deals with glaceologic time series data on snow temperature at 14 different locations within a small glacier in the Austrian Alps. A practical model building approach, consisting of model specification, estimation, and diagnostic checking, is outlined. (author's abstract) / Series: Forschungsberichte / Institut für Statistik

Synthetic aperture sonar (SAS) technology has rapidly progressed over the past few years with a number of commercial systems emerging. Such systems are typically based on an autonomous underwater vehicle platform containing multiple along-track receivers and an integrated inertial navigation system (INS) with Doppler velocity log aiding. While producing excellent images, blurring due to INS integration errors and medium fluctuations continues to limit long range, long run, image quality. This is particularly relevant in mine hunting, the main application for SAS, where it is critical to survey the greatest possible area in the shortest possible time, regardless of sea conditions. This thesis presents the simulation, design, construction, and sea trial results for a prototype "active beacon" and remote controller unit, to investigate the potential of such a device for estimating SAS platform motion and medium fluctuations. The beacon is deployed by hand in the area of interest and acts as an active point source with real-time data uploading and control performed by radio link. Operation is tightly integrated with the operation of the Acoustics Research Group KiwiSAS towed SAS, producing one-way and two-way time of flight (TOF) data for every ping by detecting the sonar chirps, time-stamping their arrival using a GPS receiver, and replying back at a different acoustic frequency after a fixed time delay. The high SNR of this reply signal, combined with the knowledge that it is produced by a single point source, provides advantages over passive point-like targets for SAS image processing. Stationary accuracies of < 2 mm RMS have been measured at ranges of up to 36m. This high accuracy allowed the beacon to be used in a separate study to characterise the medium fluctuation statistics in Lyttelton Harbour, New Zealand, using an indoor dive pool as a control. Probability density functions were fitted to the data then incorporated in SAS simulations to observe their effect on image quality. Results from recent sea trials in Lyttelton Harbour show the beacon TOF data, when used in a narrowband motion compensation (MOCOMP) process, provided improvements to the quality of SAS images centred on frequencies of 30 kHz and 100 kHz. This prototype uses simple matched-filtering algorithms for detection and while performing well under stationary conditions, the fluctuations caused by the narrow sonar transmit beam pattern (BP) and changing superposition of seabed multipath often cause dropouts and inaccurate detections during sea trials. An analysis of the BP effects and how the accuracy and robustness of the detection algorithms can be improved is presented. Overcoming these problems reliably is difficult without dedicated large scale testing facilities to allow conditions to be reproduced consistently.

In 1955, the New Zealand Government authorised the creation of a Special Forces unit to operate with British counterparts in Malaya to defeat a communist-inspired guerrilla insurgency. Between 1956 and 1971 elements of the New Zealand Special Air Service (SAS) were deployed on active service four times. These operational deployments included periods of time in Malaya, Thailand, Borneo and South Vietnam. The research illustrates the chronological progression of the New Zealand SAS through two of its most influential active service campaigns by examining how commitments to the Borneo ‘Confrontation’ in 1965 and 1966 directly and indirectly influenced the deployment to South Vietnam between December 1968 and February 1971. The mission of the New Zealand SAS in South Vietnam was to ‘assist in providing long range reconnaissance patrols’ that would support the larger infantry elements in defeating the Vietcong and North Vietnamese Army enemy. New Zealand SAS soldiers participated in 169 Australian SAS patrols in South Vietnam. Of those, 137 were commanded by the New Zealanders themselves. The research describes what the New Zealand SAS encountered during nearly two and a half years in South Vietnam; from the tactical intensity associated with small five-man patrols often observing or contacting much larger enemy formations, to the uncompromising professional standards that were expected of all members regardless of situation or circumstances and the influences of experienced Patrol Commanders, and the frustrations and inflexibility which characterised the relationship with their Australian counterparts. The research also further examines the underlying issue of overall strategic success and value of a small nationally-identifiable and strongly independent military unit that was compelled to operate under the command of larger Special Forces coalition counterparts and the impact different political, doctrinal, tactical cultural and cognitive characteristics had on these joint-operational deployments. The size of the New Zealand SAS contribution to the Australian SAS Squadron combined with the command arrangements placed upon it, also dictated that the deployments were never likely to be able to exert influence in any ‘independent’ or nationally-identifiable sense, and the relationships, the types of patrol operations conducted, and the value of these operations, would ultimately see many New Zealand SAS veterans largely dissatisfied with the overall performance of the deployment. Nevertheless, the strength of New Zealand SAS operations in South Vietnam came from its practical application of unique New Zealand Special Forces methodology and field-craft which had been fundamentally shaped and developed in Borneo. The New Zealand SAS operations in South Vietnam and Borneo - the demonstration of the highest standards of patrol techniques, tracking, reconnaissance, ambushing and fire discipline, and above all, operational professionalism that has been the hallmark of New Zealand's military history – provided the evolutionary ‘platforms’ from which today’s highly skilled and enviable New Zealand Special Forces have emerged.
