Firstly, the mechanical removal of the caruncle seeds was performed, after being pre-soaked for 24 hours and irradiated with cobalt60 gamma radiation (0, 50, 100, 150 and 200Gy) and, then, sown in polystyrene trays containing soil. Parameters such as electrical conductivity, emergence index and emergence rate, growth parameters and analysis of antioxidant enzymes (SOD, CAT and APX) measured/assessed in leaves and roots of castor bean plantlets /seedlings were evaluated. The results were submitted to ANOVA and the averages compared through Turkey test (5%). The electrical conductivity was not affected by the radiation doses used. The results showed that gamma radiation negatively affected plantlets/seedlings development, given that the dose of 200Gy significantly reduced emergence and speed of emergence index. The growth parameters showed a reduction in the plantlets size with the increase of radiation doses. The activities of antioxidant enzymes, superoxide dismutase showed a significant difference only at a dose of 200Gy to the leaves, not being significant to the roots. The activity of the enzyme ascorbate peroxidase showed increased activity in the leaves as the radiation doses were also increased. The activity of catalase showed no significant difference when exposed to different doses of gamma radiation in both leaves and roots. From the foregoing it can be concluded that the doses of Co60 gamma radiation used in this study were shown to have a negative effect on the morphological and physiological characteristics evaluated in this work. Regarding the activity of antioxidant enzymes (SOD and APX), the shoots of seedlings of castor bean was more sensitive to gamma radiation Co60 used. / O presente estudo teve por objetivo avaliar a radiossensibilidade de sementes de mamona cultivar IAC80 submetida a diferentes doses de radiação gama cobalto60. Primeiramente foi feita a remoção mecânica da carúncula das sementes, foram préembebidas por 24h em água destilada e irradiadas com radiação gama cobalto60 (0, 50, 100, 150 e 200 Gy) e posteriormente semeadas em bandejas de isopor contendo solo. Foram feitos testes de condutividade elétrica, emergência e índice de velocidade de emergência, análises de crescimento e análise das enzimas antioxidantes (SOD, CAT e APX) avaliadas nas folhas e nas raízes de plântulas de mamona. Os resultados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey (5%). A condutividade elétrica não foi afetada pelas doses de radiação utilizadas. Os resultados mostraram que a radiação gama afetou negativamente o desenvolvimento das plântulas, sendo que a dose de 200Gy reduziu significativamente a emergência e o índice de velocidade de emergência. As características morfofsiológicas apresentaram redução do tamanho das plântulas conforme o aumento das doses de radiação. Na atividade das enzimas antioxidantes, a superóxido dismutase apresentou diferença significativa apenas na dose de 200Gy, para as folhas, não sendo significativa nas raízes. A atividade da enzima ascorbato peroxidase mostrou aumento da atividade nas folhas conforme o aumento da dose de radiação. Já a atividade da catalase não mostrou diferença significativa quando exposta a diferentes doses de radiação gama tanto em folhas quanto em raízes. A partir do exposto pode-se concluir que as doses de radiação gama Co60 utilizadas neste estudo mostraram ter um efeito negativo sobre as características morfofisiológicas avaliadas neste trabalho. Quanto à atividade das enzimas antioxidantes (SOD e APX), a parte aérea das plântulas de mamona se mostrou mais sensível às doses de radiação gama Co60 utilizadas.

Un appareil de mesure de la fluorescence, à faible coût et portable a été développé pour quantifier les concentrations d’Ochratoxine A (OTA) dans des échantillons réels. Le système est basé sur l’excitation par une UV-LED à 365 nm et un photo détecteur contrôlé par une interface dans LabVIEW. Aussi, une image capteur, CMOS, contrôlée par une interface conçue dans MATLAB. L’OTA est une molécule naturellement fluorescente. Après excitation par une UV-, l’image de la fluorescence émise est captée par une caméra et traitée en vue de la mesure de la concentration de l’OTA. Le système d’analyse a été basé sur les 3 composants rouge, vert et bleu (RGB, selon l'acronyme anglais). La gamme est linéaire entre de 2-40 µg/L. L’extraction de l’OTA est réalisée par des colonnes d'immuno affinité (IAC, selon l'acronymeanglais) et les colonnes à empreinte moléculaire (MIP, selon l'acronyme anglais) pour les échantillons de cacao, de la bière et du vin. Les résultats obtenus ont été validés par la méthode chromatographique (HPLC). L'appareil conçu est facile à utiliser, économique et portable. En outre, l'utilisation des nouvelles technologies a été inclus tels que l'emploi du smartphone pour détecter l'OTA et la création d'un APP. Des données d'image de fluorescence provenant de la caméra du smartphone et sont analysées par un ordinateur personnel et présentés dans les composantes RGB, où l'image est envoyée à l'ordinateur par WIFI et le téléphone intelligent est utilisé comme source d'énergie trop. Enfin, une APP pour le système Android a été créé pour capturer l'image et fournit les valeurs RGB. Enfin l'utilisation du traitement de l'image a été utilisée pour quantifier l'OTA dans les échantillons réels sans colonnes IAC ou MIP, employée pour extraire la mycotoxine. L’analyse a été réalisée par des techniques colorimétriques et d’analyse de la couleur. / A portable and low cost fluorescence set-up to quantify the concentrations of Ochratoxin A(OTA) in real samples was developed. The detection through the device consist of anultraviolet light at 365 nm and an photo detector or a CMOS sensor controlled by anexecutable interface designed in LabVIEW or MATLAB. It has been reported that OTA is naturally fluorescent, so it allows the user to get a UV LED to excite the sample, get a value involtage when a photodetector is employed or a photograph of the OTA under excitationconditions, and process that image in order to predict the concentrations of the sample. Tocapture and process the image, in an automatically manner, the system was completely basedon the Red, Green and Blue (RGB) components. The linearity for OTA obtained in the rangeof concentrations corresponds to 2-40 µg/L. Immunoaffinity columns (IAC) and molecularimprinted polymer columns (MIP) were used with cocoa, beer and wine samples. Theobtained results were cross-validated using chromatographic method such as HPLC and theFluoroskan equipment. The developed setup is easy to use, economical and portable. Besides,the use of new tendencies was included such as employ the smartphone to detect OTA and thecreation of an APP. Fluorescence image data from the smartphone camera are analyzed by apersonal computer and presented in RGB components, where the image is sent to thecomputer by WIFI and the smartphone is used as a power source too. Finally, an APP forandroid system was created to capture the image and provides the RGB values. At the end, theuse of image processing to quantify the OTA in real samples without incorporated IAC or MIPcolumns to extract the mycotoxin from a complex solution, employing colorimetric techniquesand color analysis.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The present research work had as objective to analyse the relation between the municipalities of the State of Rio Grande do Sul affected by the droughts according to the emergency decrets and to the index of rain anomaly (IAC) in the period of 1991 to 2012. The motodology constituted of the analysis of pluviometric preciptation data acquired in the website HidroWeb of National Agency of Water (ANA) and in the National Institute of Meteorology (INMET) website using the Index of rain anomaly developed by Rooy (1965) and data of emergency decrets provided by the Civil Defense - RS. Data were analysed in order to identiy the municipalities affected by the droughts and its caracterization considering nagatives preciptation anomalies occurences according to IAC. Utilizating data from IAC, it was verified duration periods, itensity and droughts frequency by municipality. The emergency decrets where analysed in order to verify the total amount in the State, and on each municipality. In the end, it was realized an integrated variable analisys, to determinate the period of duration and intensity of the droughts by minicipalities issued emergency decrets in the analisys period. The results showed, that the majority of the emergency decrets analyzed were recorded after three consecutive months of droughts ranging from smooth to moderate, and the droughts acording to IAC occured mostly in the western State, mainly on summer, autun and winter. Furthermore, it was observed that the second hald of the analised period, a greater doughts month number by municipalieties, higher percentual of affected areas by negatives anomalies of preciptation, mostly negative rain anomaly rates, besides a greater number of recorded emergency decrets, that indicates a tendency a decrese on pluviometrics preciptations in the State of Rio Grande do Sul in the last decade, in the analised period. / O presente trabalho de pesquisa teve como objetivo analisar as relações entre os municípios do Estado do Rio Grande do Sul afetados pelas estiagens de acordo com os decretos de situação de emergência e o Índice de Anomalia de Chuva (IAC) no período de 1991 a 2012. A metodologia consistiu na análise de dados de precipitação pluviométrica adquiridos junto ao site HidroWeb da Agência Nacional das Águas (ANA) e no site do Instituto Nacional de Meteorologia (INMET) utilizando o Índice de Anomalia de Chuva (IAC) desenvolvido por Rooy (1965) e dados de decretos de situação de emergência oriundos da Defesa Civil-RS. Os dados foram avaliados visando à identificação dos municípios afetados pelas estiagens e a caracterização destes considerando as ocorrências de anomalias negativas de precipitação de acordo com o IAC. Com a utilização dos dados do IAC, foram verificados, os períodos de duração, intensidades e frequências dos eventos de estiagem por município. Os decretos de situação de emergência foram avaliados de forma a verificar o número total de decretos registrados no Estado, e em cada município. Por fim, realizou-se a análise integrada das variáveis, para determinar o período de duração e intensidade das estiagens por decretos de situação de emergência emitidos pelos municípios do Estado no período de análise. Os resultados mostraram, que a maioria dos decretos de situação de emergência avaliados foram registrados após três meses consecutivos de estiagem com intensidades variando de suave a moderada, e que os eventos de estiagem de acordo com o IAC ocorreram em sua maioria no setor Oeste do Estado, principalmente nas estações do verão, outono e inverno. Ademais, foram observados na segunda metade do período de análise, um maior número de meses com estiagem por município, maiores percentuais de áreas afetadas por anomalias negativas de precipitação, índices de anomalia de chuva anuais negativos em sua maioria, além de um maior número de decretos de situação de emergência registrados, o que indica uma tendência de diminuição das precipitações pluviométricas no Estado do Rio Grande do Sul na última década do período de análise.

Public policies are, at once, the means for articulation of political philosophies and processes, the conduits for conversion of political and bureaucratic decisions into actions and the means by which the electorate can assess government performance. Public policy processes offer a means of achieving social and economic change and they are a primary justification for the existence of governmental systems. On these counts, identification of the elements of policy processes and the ways they interact with each other is essential to an understanding of the relationships between public policy decisions, systems of democratic government and their connections with wider society. This thesis goes behind the facade of public policy outcomes and analyses the processes involved in arriving at policy decisions. Linkages are traced between political theories, the processes of public policy decisions and final policy outcomes. This involves, first, an examination and critique of liberal-democratic theories. Second, there is detailed examination of pluralist democratic practice, which is the prevailing political paradigm of modern western liberal-democratic societies. The analysis finds substantial evidence of gross distortions in the process relative to normative theories. Plain causes are the institutionalisation of special interests to the exclusion of wider public interests and inadequate accountability of governments and bureaucracies for their actions. Policy processes in pluralist systems are examined and it is concluded that the social environment, institutional influences and factors which affect the behaviour of institutions are key elements explaining public policy decisions. The capacity for pluralism to significantly influence policy outcomes depends largely on the degree and nature of access to the public policy process at various points. In examining the role of government institutions in public policy processes, it is argued that a clear distinction between the elected legislature and the administrative bureaucracy is artificial and misleading. Further, there is evidence that public service bureaucrats can become captives of their particular client groups and, thus, less accessible to the full range of relevant interests. These problems are exacerbated by the two-party Westminster model of representative democracy which tends to concentrate power in cabinet government, resulting in a decline in the importance of parliament as a deliberative and scrutinising bodies. This dissertation develops the view that there are significant causal links between institutional philosophies and values and the dominant disciplines within institutions. It is also argued that growing professionalism in bureaucracies and a tendency for functional divisions of public policy to be in broad symmetry with the divisions of the professions, tends to intensify the influence of particular professional disciplines on related areas of public policy. The critique of liberal-democratic theories and the related discussion of factors affecting policy processes in a pluralist system are used to identify the essential elements of public policy processes. It is proposed that all policy processes contain the four elements of pluralism, access, accountability and planning which are interactively related. Differences in emphasis given to these elements in the policy process explains the nature of individual policy decisions. Thus, the normative policy process datum model provides both a static and dynamic framework for analysing policy decisions. In order to examine the theoretical arguments in an empirical context, the policy processes of the Australian Federal Government, in the area of industry assistance, are analysed. This policy arena contains all the 'raw material' of pluralist processes and is, therefore, a fertile area for analysis. Furthermore, operating within this policy arena is the Industries Assistance Commission [IAC], a bureaucratic institution which is quite unlike traditional administrative structures. The IAC has, prima-facie, all of the features of the policy process datum model; it operates in an open mode, it encourages a range of pluralistic inputs, it has a highly professional planning function and, because its policy advice is published, it encourages scrutiny and accountability of itself, other actors in the bureaucracy and the elected government. The IAC operates in a rational-comprehensive mode. The analysis concludes that the IAC was established in part to be a countervailing force to restore some balance in the industry policy arena. In this it has been partly successful - the distributive policy decisions of governments have come under much greater scrutiny than in the past and other areas of the bureaucracy have been forced to operate more frequently in a rational-comprehensive mode, rather than as advocates of sectional interests. The IAC has itself limited its range of objectives, however, and has tended to become a computational organisation, isolating its core economic [planning] technology from the interactive processes of the policy process model, i.e. pluralism, access and accountability. By protecting its essential philosophy in this way, the IAC runs the risk of becoming less influential in the overall policy process. Using the policy process model as a datum, and the empirical experience of the IAC and the policy arena in which it operates, several options for administrative reform are examined. A summary agenda for administrative change is proposed which revolves around ways of achieving balanced pluralistic inputs, a greater degree of access, better bureaucratic and government accountability and ways of exploiting but controlling technocratic planning expertise. Emphasis is placed on the need to achieve enriched interactive flows between each of these key elements. If these conditions can be met, it is proposed that a revised and improved administrative bureaucracy will emerge.

In 1982, a new model of psycho-educational assessment, called the Initial Assessment and Consultation Approach (IAC), was introduced into the Education Clinic of the Division of Specialised Education at the University of the Witwatersrand (WITS). It has continued to be used in the new Emthonjeni Centre at WITS University. The IAC assessment model was developed in response to criticisms and limitations of existing assessment practices. It represents an approach that is client oriented, in that it encourages consultants and clients to arrive together at their own decisions. Key to the model is a joint problem-solving approach, where the concept of the client’s control, consent and commitment are imperative. The aim of this study was to explore student consultants’ perceptions of the IAC model of assessment. More specifically, the study explored the perceptions of the effectiveness of the IAC as a tool for psycho-educational assessment; the student consultants’ opinion regarding the model and lastly past students’ use of the IAC approach at internship sites or places of work. The results of the study were qualitatively examined through the use of thematic content analysis, which provided rich description participants’ opinions. The sample consisted of forty respondents. Information letters were distributed to all participants and data was gathered through the use of an online questionnaire. The questionnaire was structured specifically to elicit the participants’ perceptions of the IAC model of psycho-educational assessment. The results indicate that the IAC is perceived as an effective approach to psycho-educational assessment, by student consultants at WITS University, and many of the principles of the approach are continued to be adopted by past students at their internship sites or places of work.

The first cycle of quality assurance (QA) was conceptualised and developed between 2001 and 2004 as reflected in the policy documents of the Higher Education Quality Committee (HEQC). The HEQC as the national QA agency was created as the permanent sub-committee of the Council on Higher Education (CHE) to take care of the QA responsibility in 2001. The national QA agency had to operate within the divisions created in higher education under apartheid, which often created perceptions based on prejudice about the distribution of quality. The South African higher education landscape has been exposed to the first cycle of the Higher Education Quality Committee QA cycle during which conducted 34 institutional audits, accredited approximately 5000 new programmes, subjected 85 programmes to national reviews, trained approximately 550 institutional auditors and 1500 programme evaluators and conducted many workshops and training opportunities for higher education institutions (HEIs). The main aim posed by this study was to determine the response of HEIs to the recommendations in the HEQC audit reports. The sub-questions of the research are (i) What process was followed to develop the quality improvement plan? (ii) Who were the role-players in the development of the quality improvement plan? (iii) What influenced their actions in the development of the quality improvement plan? (iv) What value did the quality improvement plan development have for the institution? (v) How does the quality improvement plan fit into the comprehensive quality management system of the institution? To answer the research questions, interviews were carried out on six participants. The findings were that the primary research question has been addressed conclusively by the three institutions through the experience of participants. The responses indicate how they have embraced improvement at the respective institutions which in turn have grown as a result of the HEQC audit process. The conclusion was an in depth response to the recommendations in the audit reports, illustrating ownership of quality improvement plan processes within the institutions. From the results of the secondary research questions it is concluded that the participants’ responses provided the richness of the quality improvement plan process in the audit process. The responses reflected and confirmed the processes followed in developing the quality improvement plans and the role and influence of role- players in the quality improvement plan process. The responses reflected the value of this process and revealed how it had been incorporated into the comprehensive annual planning processes of the institutions. The study concludes that the participating institutions responded differently and effectively to the recommendations in the HEQC audit reports, with the improvement reflected in the manner and approach institutions displayed when responding to recommendations, reflecting systematic processes.
