Adição de policloreto de alumínio e remoção de peixes bentívoros como técnicas de restauração de lagos rasos do semiárido brasileiro

Eutrophication is the most common cause of water quality degradation in the world. This process occurs by excessive nutrients inputs, nitrogen and phosphorus, to the aquatic systems resulting in algal and cyanobacterial blooms. In shallow lakes these effects are pronounced due to the higher interaction of the lake with watershed, air and sediment. There are innumerous restoration techniques of eutrophied lakes with a range of successful results but there is only one case of successful lake restoration in Brazil: Paranoá Lake in Brasília city. The Brazilian semiarid region has many artificial lakes, named açudes, which are mostly eutrophic and shallow lakes. The eutrophication in these lakes is reported and the phytoplankton community is dominated by potentially toxic cyanobacteria species, mainly Cylindrospermopsis raciborskii. The aim of this thesis is to test techniques for water quality management which can be easily applied in Brazilian semiarid lakes. Results from a laboratory experiment suggest that the addition of a phosphorus sorbent clay associated with an aluminium based coagulant is an effective technique in removing soluble reactive phosphorus and reducing C. raciborskii growth rate – cyanobacteria potentially toxic dominant in reservoirs of Brazilian semiarid – but this effect is dependent on the biomass in the application moment. Results from a field experiment in mesocosm in a eutrophied lake showed that the addition of aluminium based coagulant and removal of benthivorous fish is more efficient in removing total phosphorus and chlorophyll-a from water column than the isolated application of one of the techniques. Lastly, laboratory tests showed that aluminium based coagulant exhibited good performance in removing turbidity and total phosphorus from water of six reservoirs but the efficiency was reduced by algal biomass and pH. The results of this study showed that the improvement in water quality of eutrophied reservoirs in semiarid region is possible through internal loading control by phosphorus precipitation and inactivation in sediments or inhibition of phosphorus release by benthivorous fishes, and also that these results show are additives in water quality improvement.

A Anatomia da Gestão Estratégica: neuroeconomia, gestão de recursos humanos e sistema de gestão de qualidade

Contexto: O trabalho que a seguir se apresenta foi elaborado no âmbito de um novo conceito na gestão do desempenho organizacional, a gestão estratégica multidimensional, onde a neuroeconomia foi associada à perspetiva teórica da gestão estratégica de recursos humanos (Dessler, 2005) e à aplicação do sistema de gestão da qualidade (SGQ), da NP 9001: 2008 (Saraiva e tal, 2009), para formar um método eficaz de conceção dos percursos de operacionalização da organização Objetivos: Pretendeu-se construir uma forma anatómica de gestão de desempenho organizacional através dos três conceitos mencionados, num contexto de gestão estratégica multidimensional, possibilitando a sua quantificação pelo nível de implementação dos requisitos para um sistema de gestão de qualidade, com o intuito de verificar sua viabilidade, sendo a resiliência organizacional dependente em grande medida dos recursos humanos, Método: Pelo conjunto das três áreas mencionadas foi criado um guia de atuação abrangendo as bases fundamentais para o desenvolvimento de uma estrutura organizacional: verificação dos níveis de incidência da gestão do desempenho organizacional; caracterização de diferentes tipos de estratégias de intervenção; implementação de estratégias preventivas e estratégias corretivas; utilização das quatro dimensões PIPE – performance, inovação, processos e empenhamento – como estratégias corretivas; integração das estratégias preventivas com as estratégias corretivas; diagnóstico contínuo de situações problema na gestão do desempenho organizacional; conceção de percursos de intervenção na gestão do desempenho organizacional; conceção de um projeto de gestão estratégica. A amostra final é constituída por uma organização do 3ºsetor, nomeadamente uma IPSS, a Associação Recreativa Cultural e Social das Gândaras, na Lousã, no distrito de Coimbra. Resultados: Com efeito, acredita-se que com este trabalho seja possível quantificar o nível de implementação dos requisitos para um SGQ num contexto de gestão estratégica multidimensional. / Context: The work presented below was prepared as part of a new concept in the management of organizational performance, the multidimensional strategic management, which was associated the neuroeconomics perspetive with the human resourses strategic management (Dessler, 2005) and the application of the quality management system (QMS), NP 9001: 2008 (and such Saraiva, 2009), to form an effective method of conception paths of operation of the organization Objetives: It was intended to build an anatomical shape organizational performance management across the three concepts mentioned in the context of multidimensional strategic management, enabling to quantify the level of implementation of the requirements for a quality management system, in order to verify their viability , and the organizational resilience largely dependent on human resources. Method: For all the three areas mentioned has created an action guide covering the fundamentals for developing an organizational structure: the verification of the incidence levels of organizational performance management; characterization of different types of intervention strategies; implementation of preventive strategies and corrective strategies, using the four dimensions PIPE - performance, innovation, processes and commitment - as corrective strategies; integration of preventive strategies with remedial strategies; diagnosis of problem situations in the ongoing management of organizational performance; conception pathways of intervention in the management of organizational performance; conception of a project of strategic management. The final sample consists of an organization of the 3rd setor, an IPSS, the Associação Recreativa Cultural e Social das Gândaras, in Lousã, in the district of Coimbra. Results: In fact, it is believed that this work is possible to quantify the level of implementation of the requirements for a QMS in a multidimensional context of strategic management.

Programa de aquisição de alimentos (2003-2010): avaliação da implementação pela CONAB no Rio Grande do Norte

This thesis aimed to evaluate the implementation of the Food Acquisition Program(PAA) through CONAB RN in the period of 2003-2010 with the perception of all agents involved in the implementation of the government program.For the methodological trajectory it was adopted a descriptive bibliographical and documentary approach with triangular qualitative and quantitative, also called evaluative research.The theoretical model was supported by the authors Draibe (2001), Aguilar and Ander-Egg (1994) and Silva(2001), among others, that focused on family farming and evaluation of implementation of public policy having as a category of analysis the size implementation of policy and the latter divided into 10 theoretical dimensions.The universe consisted of three groups: the first were the managers and technicians from CONAB(RN and Brasilia), totaling 15 subjects. The second group was of associations/cooperatives that participated in the programin 2010, totaling a sample in each access of 15 representatives. The third group of subjects totaled with 309 representatives of governmental and non-governmental organizations that received donations of food for the same period. Semi-structured interviews and forms were adopted as instruments of data collection.The data were processed qualitatively by the analysis of content (interviews and documents) and quantitatively by means of statistical tests that allowed inferences and adoption of frequencies. Among the key find ingests that the program is not standing as a structure supported by planning. The interests of the performers do not necessarily converge with the objectives of the Food Acquisition Program (PAA). A shockof goals was identified (within the same program) when comparingthe financial agent (Ministry of Rural Development and of Social Development and Fight Against Hunger Ministry r) and the executor, CONAB/RN. Within the assessed dimensions, the most fragileis the sub-managerial decision-making and Organizational Environment and internal assessment, still deserves attention the sizeof logistical and operational Subsystem, as this also proved weak.The focusin the quest toexpand thequantificationof the resultsof theFood Acquisition Program (PAA)by CONAB/RN does forget a quality management focused on what really should be:the compliance with the institutional objectives of the government program.Finally, the perspective for the traded implementation should be re-examined because excessive discretion by managers along with technical staff has characterized there al role of the Food Acquisition Program (PAA) as public policy. We conclude that the implementation model, which apparently aggregates values to the benefitted citizens, has weakened the context of work on family farms having the management model of the implementation process be reviewed by the Federal Government and point too ther paths, which have as a guide line the emancipation and developmentof the field or in the field andat the same time enables the reduction of nutritional deficiency of beneficiaries in a balanced and coherent way

A satisfação profissional e a cultura organizacional : uma análise a partir do modelo ASH no Centro Federal de Educação Tecnológica do Rio Grande do Norte

With the need of the companies in becoming more competitive within the market, it arises an incessant search for selective human potential, with a high level of capacity and low rotativity, which motivation results in production raise, quality optimization and waste reduction. This scenario requires a strategy development which advantages the Human Resources Quality Management. This way, the model of the Human System Audit (HSA), developed by the Spanish researchers Ouijano and Navarro, presents itself as an important tool to diagnosis and evaluation, contemplating the environment where the organization is inserted, its strategies, its organizational design, its processes and its organizational effectiveness. In this sense, the present study has identified the existent relation between the professional satisfaction and the Organizational Culture, based in the model HSA. The research has been a quantitative-descriptive one and has had as population the technical-administrative workers from the Federal Center of Technical Education of Rio Grande do Norte (CEFET RN). The data collection has occurred during May, 2008, by means of the application of a questionnaire in the HSA model. The sample was composed by 167 subjects, distributed among the Five units of the institution. It was used the factorial analysis, with the extraction method of main components and orthogonal rotation varimax, in order to extract the dimensions of the satisfaction and of the organizational culture and the calculation of Cronbach s Alpha coefficient, to evaluate the reliability of these dimensions. The factorial analysis of the satisfaction indicators has identified four factors,, all of them showing significance: gratefulness and relationship , self-realization , stability and security and physical conditions and social benefits . The result of the factorial analysis with the indicators of the organizational culture has extracted four factors and among them, three of them have obtained significance: Personal Satisfaction Style , Competitive-Denial-Power Style and the Conventional-Dependent Style . After identifying the dimensions of the satisfaction and culture found at CEFET-RN, it has been notice the existence or not of relation among them, through the application of Pearson s coefficient. It has been verified that all of the dimensions of the Professional satisfaction are correlated with some dimension of the organizational culture, having in outstand position, with higher intensity, the relation between the culture style of Personal Satisfaction and the satisfaction factor referring to the self-realization

Challenges to improve inter-professional care and service collaboration for people living with psychiatric disabilities in ordinary housing

The aim of this study was to describe health care- and social service professionals' experiences of a quality-improvement program implemented in the south of Sweden. The focus of the program was to develop inter-professional collaboration to improve care and service to people with psychiatric disabilities in ordinary housing. Focus group interviews and a thematic analysis were used. The result was captured as themes along steps in process. (I) Entering the quality-improvement program: Lack of information about the program, The challenge of getting started, and Approaching the resources reluctantly. (II) Doing the practice-based improvement work: Facing unprepared workplaces, and Doing twice the work. (III) Looking backevaluation over 1 year: Balancing theoretical knowledge with practical training, and Considering profound knowledge as an integral part of work. The improvement process in clinical practice was found to be both time and energy consuming, yet worth the effort. The findings also indicate that collaboration across organizational boundaries was broadened, and the care and service delivery were improved.

What is best for Esther? Building improvement coaching capacity with and for users in health and social Care-A case study

While coaching and customer involvement can enhance the improvement of health and social care, many organizations struggle to develop their improvement capability; it is unclear how best to accomplish this. We examined one attempt at training improvement coaches. The program, set in the Esther Network for integrated care in rural Jonkoping County, Sweden, included eight 1-day sessions spanning 7 months in 2011. A senior citizen joined the faculty in all training sessions. Aiming to discern which elements in the program were essential for assuming the role of improvement coach, we used a case-study design with a qualitative approach. Our focus group interviews included 17 informants: 11 coaches, 3 faculty members, and 3 senior citizens. We performed manifest content analysis of the interview data. Creating will, ideas, execution, and sustainability emerged as crucial elements. These elements were promoted by customer focusembodied by the senior citizen trainershared values and a solution-focused approach, by the supportive coach network and by participants' expanded systems understanding. These elements emerged as more important than specific improvement tools and are worth considering also elsewhere when seeking to develop improvement capability in health and social care organizations.

Curricular training report: clinical studies coordination in a clinical research organization vs an investigational site perspective

This report describes my experience of nine months as a trainee of a CRO (Eurotrials, Scientific Consultants), as well as a trainee of a clinical research site (Clinical Academic Center – Braga, Association). This document describes the European framework about clinical research and the Portuguese situation compared to similar countries. The activities developed during this internship are also described. These activities are divided in two phases. The first one occurred in Eurotrials, Scientific Consultants, a CRO specialized in clinical research and scientific advice. The first weeks were dedicated to intensive self-training needed to perform CTA tasks. These tasks included qualification, initiation and monitoring activities related to clinical trials, as well as the development of a quality management system. The second phase took place on 2CA-Braga, a clinical research center located in Hospital of Braga. Clinical studies coordination was the main focus of this second phase of my internship, as well as negotiation of clinical studies agreements. I had also the opportunity to participate in “1as Jornadas de Investigação Clínica e Inovação” (1st Clinical Investigation and Innovation Conference) organized by 2CA-Braga. Globally, this internship was a great opportunity to get knowledge and experience in the implementation and management of clinical trials, in a CRO and clinical research site perspectives. These two perspectives provided an interesting overview about the scientific needs of different players involved in clinical research. To conclude, this internship strengthened the knowledge acquired from my academic background, which make me able to face and overcome new challenges in the clinical research area.

Composição do fitoplâncton e cianotoxinas em um reservatório utilizado para o abastecimento público: o efeito do tratamento de água convencional.

Florações de cianobactérias nocivas ocorrem frequentemente em reservatórios brasileiros, devido ao incremento de nutrientes pela eutrofização e pelas mudanças climáticas, como o aquecimento global. Estas florações alteram a qualidade dos corpos hídricos, produzindo compostos de gosto e odor e cianotoxinas, que representam um problema para as Estações de Tratamento de Água (ETAs). Estes compostos, quando dissolvidos na água dificultam os tratamentos convencionais. Além das cianobacérias, um dinoflagelado exótico tem ocorrido em águas doces brasileiras, incluindo reservatórios utilizados para o abastecimento público. Os reservatórios de Caxias do Sul (RS – Brasil) são gerenciados pelo Serviço Autônomo Municipal de Água e Esgoto (SAMAE) e apresentam um histórico de florações de cianobactérias nocivas, como Dolichospermum Bory de Saint-Vincent ex Bornet & Flahault e Microcystis (Kützing) ex Lemmermann, dentre outras. Além disso, desde 2012, tem ocorrido nestes reservatórios florações de Ceratium furcoides. Este organismo quando em extensas florações tem sido relacionado à perda da qualidade dos corpos hídricos. O reservatório Maestra foi construído entre os anos de 1965-1970 e abastece 22% da população de Caxias do Sul. Este reservatório fornece água para a ETA Celeste Gobatto, que utiliza o método convencional de tratamento da água. Este trabalho esta estruturado em três capítulos. O primeiro consiste de uma revisão bibliográfica de assuntos relavantes acerca do histórico do monitoramento da qualidade dos reservatórios no Brasil, da biologia de algas e cianobactérias, e as principais cianotixinas e acidentes devido à intoxicação no Brasil. Além disso, é feita uma breve revisão sobre o tratamento convencional da água, mostrando a importância de cada etapa para a remoção das impurezas, de acordo com os padrões de potabilidade da Portaria 2914. O segundo capítulo é manuscrito na forma de artigo científico intítulado “Composição de algas, cianobactérias e cianotoxinas no reservatório Maestra – Caxias do Sul, RS – Brasil”. Este estudo foi realizado entre janeiro de 2012 a abril de 2013. O terceiro capítulo consta de um manuscrito na forma de artigo científico, intitulado “Efeito do tratamento de água convencional na remoção de algas, cianobactérias e cianotoxinas em uma Estação de Tratamento de Água Convencional”. A eficiência de remoção foi avaliada em escala piloto, em uma Estação de Tratamento de Água de Caxias do Sul – RS a qual utiliza o método convencional de tratamento.

Avaliação inorgânica de material particulado atmosférico inalável na região norte do Paraná

This study aimed to determine the concentration and inorganic chemical composition of samples from airborne particulate matter inhaled in fine and coarse fractions. Aerosol samples were collected in 2013 and 2014, from sites located in the cities of Londrina and Maringa, in the state of Paraná, Brazil. The samples were collected daily (24h) in two campaigns: winter and summer. For the collection, was used a dichotomous sampler with quartz fiber filter with 47 mm in size and 2 µm porosity, 97% efficiency, retaining particles of up to 0.3 µm. Quantification of the airborne particulate matter mass was performed by gravimetry method. The results from Londrina to PM2.5 and MP2,5-10 represent, respectively, 29.2% and 70.8% of airborne particulate matter in the winter campaign (2013), 30.9% (PM2.5) and 69.1 % (MP2,5-10) in the summer campaign (2013), and 35.9% (PM2.5) and 64.1% (MP2,5-10) in the winter 2014 campaign. In the city of Maringa, the results presented the percentage of 42.0% (PM2.5) and 58.0% (MP2,5-10) for the winter season (2014), and 28.8% (PM2.5) and 71.2 % (MP2,5-10) for the summer season (2014). The PM2.5/PM10 ratio was on average 0.3, demonstrating that both cities are developing urban areas. Analysis of the major soluble inorganic species in water (NO3-, SO42- and Cl-) associated with MP2,5-10 were quantified by ion chromatography at the LACA Laboratory in the State University of Londrina, with the largest contribution found in all campaigns was to NO3-. The NO3-/SO42- ratios above 1.0 indicate the local traffic contribution. The analysis of metals associated with PM2.5 was carried out by mass spectrometry with inductively coupled plasma (ICP-MS) in the Federal University of Santa Catarina. The Zn, Pb, Cu and Mn concentrations found in all campaigns indicate the contribution of mobile sources to PM2.5. The concentration of BCe in PM2.5 was determined by reflectance, with higher BCe concentrations being found in winter campaigns. In general, Londrina presented the highest concentrations from the species analyzed when compared to Maringá. In addition, the analysis of the air mass trajectories indicated the transportation of pollutants coming mainly from fires in the southeastern region of the country.
