Frente a este problema, esta dissertação tem como objetivo principal propor um plano de gestão que vise garantir a eficiência das aquisições de bens e serviços na UFAM, bem como propor sugestões de melhorias para a gestão administrativa da Universidade. Para tanto, pesquisas bibliográficas foram realizadas acerca do planejamento em licitações nos órgãos públicos e, em seguida, foi elaborado e testado um plano de gestão adaptado a realidade da UFAM, bem como foi feita uma pesquisa de satisfação junto aos executores dos processos licitatórios. O instrumento de coleta de dados foi um questionário composto de dezenove asserções. Após a análise dos dados coletados foi possível diagnosticar os aspectos positivos e negativos do sistema de aquisições da instituição. O plano de gestão permitiu a melhora quali-quantitativa da realização dos pregões sem ferir a legislação vigente.

In this new scene, it fits to the developing countries to supply hand of cheap workmanship to the international capital. East European and countries as China, India, amongst others, had passed to represent one competition, almost disloyal, in offer of hand of workmanship, since rules basic of market inform that how much bigger offers, minor the price. Thus, countries of the European west, the North America and even though of the South America if see in a position where the improvement of the productivity of the workmanship hand represents a strong factor of the proper subsistence of the company in its markets. For this, one of the methods used for many managers of the multinationals is the comparison of productivity pointers enters its units for the world. A time detected the marcantes points, the productivity searchs to improve each time more, using itself benchmarck that they aim at one total standardization of the production, as, for example, same equipment, products, raw material, techniques and, even though, formation of staff in the other units of the world. Everything this with one only purpose: to arrive at the excellent point of productivity in all its units, not importing on which labor law, where local, economy, society and environment are its units. But, all this effort, in the great majority of the times the multinationals does not obtain to arrive at the call for us of excellent point in all its units. Hardly, if it obtains two or three units with the same productivity. But reason? To this inquiry we consider in them and we could perceive that external factors to the organization intervene decisively with organizacional behavior e, for consequence, in the productivity. In such a way, what we consider in them in this research is to demonstrate some external factors to the organization that act in the productivity, thus causing a different excellent point in each unit, having as base the study of case of the Multinational of Michelin Tires. / Com a nova configura??o mundial ap?s a queda definitiva do socialismo, uma nova divis?o internacional do trabalho se mostrou necess?ria. Neste novo cen?rio, cabe aos pa?ses em desenvolvimento fornecer m?o de obra barata ao capital internacional. O Leste Europeu e pa?ses como China, ?ndia, dentre outros, passaram a representar um uma concorr?ncia, quase desleal, na oferta de m?o de obra, visto que as regras b?sicas do mercado informam que quanto maior a oferta, menor o pre?o. Assim, pa?ses do oeste europeu, da Am?rica do Norte e at? mesmo da Am?rica do Sul se v?em em uma posi??o em que a melhoria da produtividade da m?o de obra representa um forte fator da pr?pria subsist?ncia da empresa em seus mercados. Para isso, um dos m?todos utilizados por muitos gestores das multinacionais ? a compara??o de indicadores de produtividade entre as suas unidades pelo mundo. Uma vez detectados os pontos marcantes, busca-se melhorar cada vez mais a produtividade, utilizando-se benchmarck que visam uma total padroniza??o da produ??o, como, por exemplo, mesmos equipamentos, produtos, mat?ria-prima, t?cnicas e, at? mesmo, forma??o de pessoal nas outras unidades do mundo. Tudo isso com uma s? finalidade: chegar ao ponto ?timo de produtividade em todas as suas unidades, n?o importando sobre qual legisla??o trabalhista, em que local, economia, sociedade e meio ambiente estejam suas unidades. Malgrado todo este esfor?o, na grande maioria das vezes as multinacionais n?o conseguem chegar ao chamado por n?s de ponto ?timo em todas as suas unidades. Dificilmente, se consegue duas ou tr?s unidades com a mesma produtividade. Mas porqu?? A essa investiga??o prop?s-se e p?de-se perceber que fatores externos ? organiza??o interferem decisivamente na produtividade. Desta forma, prop?e-se nesta pesquisa, demonstrar alguns fatores externos ? organiza??o que atuam na produtividade, ocasionando assim um ponto ?timo diferente em cada unidade, tendo como base o estudo de caso da Multinacional de Pneum?ticos Michelin.

It is analyzed the Brazilian experience and reality about the topic, with a specific focus on 90 decade and 2000 years.

A dinâmica paleoceanográfica no Oceano Atlântico Sudoeste ainda é pouco conhecida, com a maioria dos trabalhos descrevendo os últimos 25 mil anos. Neste estudo, foram utilizados como indicadores as assembleias fósseis de cocolitoforídeos (também chamados de nanofósseis calcários), isótopos estáveis de oxigênio e carbono (em testas do foraminífero planctônico Globigerinoides ruber), o conteúdo de carbonato nos sedimentos (fração < 0,63 μm) e datações radiocarbônicas. Foram analisados dois testemunhos, coletados no talude da Bacia de Campos, compreendendo os últimos 440 mil anos. Os resultados apontam que espécies do grupo “placolitoformes”, como Gephyrocapsa spp. e Emiliania huxleyi, e a espécie Florisphaera profunda, habitante da zona fótica inferior, dominaram a assembleia durante todo o intervalo estudado. Entre 440 - 410 mil anos a produtividade é alta, independente da alternância entre estágios glaciais/interglaciais (EIMs 12, 11, 10, 9, 8, 7 e 6). Boa parte deste intervalo de tempo está relacionada ao evento Brunhes médio, quando, no hemisfério sul, havia uma intensificação das circulações atmosférica e oceânica, aumentando a ressurgência costeira. Nos últimos 130 mil anos, existe alguma relação entre a produtividade e esta ciclicidade climática. De forma geral, pode-se dizer que os estágios interglaciais stricto sensu (EIMs 5e e 1) são menos produtivos que os demais (EIMs 5d-a, 4, 3 e 2). Durante estágios interglaciais, a Zona de Convergência Intertropical estaria deslocada para o norte, os ventos de nordeste associados à Alta Subtropical do Atlântico Sul teriam baixa intensidade e a Corrente do Brasil estaria enfraquecida, levando à manutenção da estratificação das águas. Já durante o estágio glacial, as condições inversas favoreceriam a ressurgência costeira. Ao longo dos últimos 130 mil anos, a produtividade máxima é atingida entre 14 - 6,5 mil anos (durante a deglaciação), podendo ser um reflexo dos acontecimentos do Último Máximo Glacial. Entre 440 - 140 mil anos, cocolitoforídeos parecem ter um pequeno papel no ciclo do carbono, transferindo carbonato das águas superficiais para o fundo marinho. Este papel aumenta nos 130 mil anos subsequentes. Durante todo o intervalo, espécies produtoras de pequenos cocólitos, como Gephyrocapsa spp. e Emiliania huxleyi, são as mais determinantes nesta transferência, por serem muito abundantes. / The paleoceanographic dynamic of the Southweast Atlantic is still poorly known, with most of the studies describing the last 25×103 years. In this work, fossil assemblages of coccolithophorids (also called calcareous nannofossils), oxygen and carbon stable isotopes (in shells of the planktonic foraminifera Globigerinoides ruber), the carbonate content in the sediments (< 0,63 μm fraction) and radiocarbon dating were used as indicators. Two sediment cores, recovered at the slope of Campos Basin, were analyzed, comprising the last 440×103 years. The results show that placolith-bearing species, such as Gephyrocapsa spp. and Emiliania huxleyi, and the Florisphaera profunda species, which inhabits the lower photic zone, dominated the assemblage during the whole study interval. Between 440-410×103 years there is high productivity, independent of the alternation between glacial and interglacial stages (MISs 12, 11, 10, 9, 8, 7 and 6). Much of this time interval is related to the mid-Brunhes event, when an intensified atmospheric and oceanic circulation is reported in the southern hemisphere, leading to increased coastal upwelling. Over the past 130×103 years, there was some relationship between the productivity and this climate cyclicity. In a general way, it can be said that stricto sensu interglacial stages (MISs 5e and 1) are less productive than the others (MISs 5d-a, 4, 3 and 2). During interglacial stages, a northward shift in the Intertropical Convergence Zone position would take place, together with a weakening of the northeast winds associated to the Southern Atlantic Subtropical High and a weakening of the Brazil Current, leading to the maintenance of the water stratification. On the other hand, during the glacial stage, the inverse conditions would be favorable to coastal upwelling. Over the last 130×103 years, maximum productivity is achieved between 14- 6,5×103 years (during deglaciation), which could be a reflection of the events of the Last Glacial Maximum. Between 440-140×103 years, coccolithophorids seem to have had a small role in the carbon cycle, transferring carbonate shallow waters to the seabed. This role seems to have increased in the following 130×103 years. During the whole interval, species that produce small coccoliths, such as Gephyrocapsa spp. and Emiliania huxleyi, are the most crucial in this transfer, because they are very abundant.

This thesis presents the findings of a research project to develop and implement a Lean and agile Construction System on a case study project. The aim of the research project, for the sponsor company, was to improve its projects site operations, making them safer for the worker and improving effectiveness and productivity. The findings have shown that the Construction System has proved to be a successful set of countermeasures that act as an antidote to the health, safety and productivity problems that exist in UK construction and that face the sponsor company. The System has been implemented on a large and complex mechanical and electrical case study project in the healthcare sector of UK construction. The outcome of this case study project shows that 37% less onsite labour was needed, meaning fewer workers were exposed to health and safety risks from site operations, leading to zero reportable accidents. Good ergonomics was achieved by focussing on workplace design, thus improving workers wellbeing, together with an improved quality of work for those required on site carrying out simpler assembly tasks. Productivity gains resulted by eliminating process waste, therefore reducing the risk of labour cost escalation that could otherwise have occurred. A 7% direct labour cost reduction was made meaning the labour budget allocation was maintained. Significantly, an overall productivity of 116% was achieved using the Construction System, which compares favourably to BSRIA's findings of an average overall productivity of only 37% when compared to observed best practice for the projects in that case study research. The results include the benefits found from the use of an innovative method to assemble, transport, and install frameless, preassembled mechanical and electrical services modules, where a 93% reduction in onsite labour was achieved together with an 8.62% cost benefit. No time slippage was experienced during onsite assembly to delay or disrupt other trades and the commissioning programme was not compressed that could otherwise have caused problems in handing over the facility to the customer. From a customer's perspective, the built facilities were handed over on-time, to their satisfaction and to budget. The research has achieved two levels of innovation, one at a process level and one at a product level. The process innovation is the development and successful implementation of the Construction System, which is a combination of methods acting together as an antidote to the research problem. The product innovation is the development of the innovative method for assembling, transporting and installing frameless mechanical and electrical corridor modules, whereby modularisation can be achieved with or without an offsite manufacturing capability. The System is built on Lean principles and has been shown to standardise the work, process and products to create flow, pull and value delivery. It is transferable across the sponsor company's business as well as the wider industry itself. The transformation that has occurred is the creation of a step-change in undertaking mechanical and electrical construction work, which has realised a significant improvement in performance for CHt that has "Transformed Traditional Mechanical and Electrical Construction into a Modern Process of Assembly".

The research explored ways for improving maintenance labour productivity and reducing maintenance costs. This can be achieved through reducing the number of maintenance activities and by improving the productivity of labour carrying out repair and maintenance tasks. The research established that Integrated Logistics Support (ILS) techniques, in particular, Failure Modes and Effects Analysis (FMEA) and Reliability Centred Maintenance (RCM) could be applied to building systems, in this case to the maintenance of Rainwater Goods to identify the most applicable and cost effective maintenance strategy. As a result it was found that while 60% of failure modes identified could be rectified by employing a Failure-Based Maintenance strategy, 40% of the failure modes require a Condition-Based Maintenance strategy which is not currently applied. Labour productivity is a subject of tremendous interest to research in the construction industry; the study found however, very little research on the productivity of labour in building repair and maintenance operations. It was found that measurement of building maintenance labour productivity has not been the focus of any previous studies. Indeed no measures of productivity for building maintenance were identified. Having considered a number of alternative measures, the research identified the productivity index expressed in terms of Estimated Hours/Actual hours to be the most appropriate measure of labour productivity in repair and maintenance operations. Using this measure, it was established that labour productivity is impacted by a number of variables including task performance, labour performance, material usage and seasonal variability. Among the objectives of the research was to identify the factors influencing labour productivity. Through a survey questionnaire, it was possible to identify the factors that have the greatest impact on maintenance labour productivity; these were the level of skills and motivation of workmen; quality of information and work instructions; labour turnover and absenteeism; availability of tools and material, and access to the job site. The analysis of historical repairs data from two building repair and maintenance organisations revealed that during the performance of the same tasks, one of the data sources was almost 25% more productive than the other. The research has established that there is a potential for improving labour productivity carrying out building repair and maintenance.

Resumo: A falta de detalhamento nas informações sobre os atributos do solo, nas áreas cultivadas é um fator limitante para aumentar a assertividade na alocação de variedades de cana-de-açúcar em diversos ambientes edafoclimáticos. Atualmente, o conceito de ambientes de produção é amplamente utilizado para classificar o potencial de produtividade dos solos, e a suscetibilidade magnética surge como uma ferramenta importante para mapear áreas de forma ultradetalhada e com baixo custo. Nesse contexto, este trabalho tem como objetivo avaliar a utilização da suscetibilidade magnética como ferramenta na identificação de áreas com diferentes potenciais para produtividade e qualidade de cana-de-açúcar e sua utilização na alocação de variedades. Foram amostrados 445 ha com grid de 1 ponto a cada 5 hectares e, seguindo o espigão da paisagem, foram determinados 14 pontos para amostragem estratificada. Analisaram-se a granulometria e a suscetibilidade magnética de amostras, nas profundidades de 0,0-0,2 m e 0,2-0,4 m. Os dados de produtividade e de qualidade da matéria-prima foram obtidos via banco de dados de 9 safras e biometria realizada na safra de 2018/2019. Como resultados, observou-se alta correlação dos teores de argila e de areia com a expressão magnética. Pela análise multivariada dos resultados históricos, observou-se a organização de 3 grupos com diferentes potenciais de produtividade e de qualidade, diferenciando em até 17,28TCH o resultado entre o grupo com maior e menor potencial, b...

Nowadays, the concept of production environments is used to classify soil execution potential and a magnetic increase in susceptibility as an important tool for mapping ultra-detailed and low cost areas. In this context, this work aims to evaluate magnetic susceptibility, how to use tools to identify areas with different levels of use and quality of sugarcane and its use in the allocation of varieties. 445 ha were sampled with 1 point grid every 5 hectares and, following the understanding of the landscape, 14 points were selected for stratified sampling. Particle size and magnetic susceptibility of dimensions at depths of 0.0-0.2 m and 0.2-0.4 m were analyzed. Test data and raw material quality data were obtained through a 9-crop database and biometrics performed in the 2018/2019 crop. As a result, high correlation of clay and sand content with magnetic expression. By multivariate analysis of historical results, it is possible to organize 3 groups with different levels of use and quality, differentiating up to 17.28TCH or the result between the group with higher and lower potential, based on soil magnetic susceptibility. For biometrics results, as the classes of higher magnetic susceptibility observed in the largest difference and lowest sugar accumulation. Analyzing variety...

Es evidente que la pobreza económica es uno de los problemas que presentan los países subdesarrollados, y que su reducción está relacionada con el aumento de la productividad en las PYME, dado el alto impacto que han representado a lo largo del tiempo. Muchas entidades han identificado la importancia de la agricultura en el sector económico del país. Por lo tanto, es necesario un diagnóstico en la zona. El propósito de este diagnóstico es tener una referencia del entorno desde el punto de vista general, en el que se pueden observar todas las interacciones, descripciones, particularidades y procesos existentes. En esta primera etapa del diagnóstico, se lleva a cabo utilizando un muestreo no probabilístico, que es un método común en la investigación. Uno de los muchos métodos utilizados para identificar el diagnóstico es el muestreo de bolas de nieve que permite encontrar el diagnóstico de poblaciones ocultas donde no hay manera de conocer todas las características de una población. La ventaja de utilizar este tipo de muestreo es que un solo informante inicial puede poner al investigador en contacto con otras fuentes. Además, sobre la base de los resultados obtenidos, se identificó que las causas del problema del sector de Chirimoya estaban asociadas a 3 procesos críticos que reflejaban la no productividad de este sector: proceso de gestión de planificación y control de la producción, proceso de gestión logística y proceso de gestión de la calidad. / It is evident that economic poverty is one of the problems presented by underdeveloped countries, and that their reduction is related to the increase in productivity in MSEs, given the high impact they have represented over time. Many entities have identified the importance of agriculture in the economic sector of the country. Therefore, a diagnosis is necessary in the area. The purpose of this diagnosis is to have a reference of the environment from the general point of view, in which all the interactions, descriptions, particularities and existing processes can be observed. In this first stage of the diagnosis, it is carried out using a non-probabilistic sampling, which is a common method in the investigation. One of the many methods used for identifying diagnosis is the snowball sampling that allows finding the diagnosis of hidden populations where there is no way to know all the characteristics of a population. The benefit of using this type of sampling is that a single initial informant can put the researcher in contact with other sources. Further, based on the results obtained, it was identified that the causes of the problem of the Cherimoya sector were associated to 3 critical processes that reflected the non-productivity of this sector: process of planning management and production control, process of logistic management and process of quality management. / Tesis

Mesoscale turbulence is ubiquitous in the surface ocean and has significant impact on the large-scale ocean circulation and its interaction with the climate. Ocean currents are most energetic in the mesoscale range on the scales of 20-200 km and recent studies have shown that the surface kinetic energy associated with the mesoscale undergo a large seasonal modulation. At scales below the mesoscale where geostrophic approximation breaks down lies the submesoscale (1-20 km). It is at this scale that baroclinic instabilities feed off the available potential energy stored in the deep wintertime mixed layers, known as mixed-layer instability, and in return energize the mesoscale via inverse energy cascade under the constraint of stratification and rotation. Mixed-layer instability (MLI) is inherently submesoscale due to the depth scale associated with it. We show the robustness of MLI on global scale in modulating seasonality in surface mesoscale turbulence by analyzing outputs from a Community Earth System Model fully ocean-atmosphere coupled run with eddying resolution. Due to the rigorous vertical velocities associated with mesoscale turbulence, in the context of climate, they have been shown to make major contributions to the transport of heat and tracers including carbon. More recently, it has been argued that submesoscale heat transport may dominate over the mesoscale. We ask the same question for tracers: What is the relative contribution of submesoscale transport (local effect) over the energized mesoscale via inverse energy cascade (remote effect)? In order to investigate their impact on the dynamics and tracer transport, we run our own seasonally resolving submesoscale permitting channel model configured to represent the zonal-mean view of the Southern Ocean coupled to a full biogeochemical model. The Southern Ocean is unique in that, apart from it being the only zonally re-entrant basin on Earth, it is one of the high-nutrient low-Chlorophyll oceans and iron is predominantly the limiting nutrient for primary production within the open-ocean region. As the basin responsible for generating the densest water mass properties, i.e. Antarctic Bottom Water, and outcropping isopycnals, primary production and the associated biological carbon pump have been of long interest to the biogeochemical and climate community. We provide an independent estimate from satellite observations of the seasonal cycle in phytoplankton biomass by taking advantage of the biogeochemical Argo floats, in which we show that the biomass reaches its maximum around December in the open-ocean region. Our modelled ecosystem reaches its maximum in November, roughly a month earlier, likely due to the lack of aeolian dust input at the surface, and glacial and bathymetric sources from the south in our model. Utilizing spectral analysis and the generalized Omega equation, we decompose the eddy transport of heat and iron to its submesoscale (local) and mesoscale (remote) contributions. With the exception near the surface where mixed-layer instability is active, our results indicate that mesoscale vertical transport is of first-order significance in calculating the budgets and supplying iron across the mixed-layer base to the surface where phytoplankton can effectively photosynthesize.

In a workplace marked by increasing change and competing commitments, business leaders require an increased understanding of alternative work programs. Utilizing spillover theory, motivator-hygiene theory, and adaptive structuration theory, this single case study was an exploration of the strategies that business leaders use for flexible work schedules and virtual work programs. The population consisted of 3 managerial business executives and 6 employees within a midwestern United States division of a global blood management solutions firm. The data collection process included a series of semistructured interviews, a focus group, and the assessment of company documentation. Methodological triangulation identified 5 emerging themes: program assessment and monitoring, standard set of virtual working hours, remote office setup, increased virtual communication, and promotion of quality of life. The transferability of this single case study remains with the reader and future researchers to determine. Future researchers may discover that the findings contribute to social change by better preparing organizations for success while simultaneously positioning individuals to attain optimum balance across life and work responsibilities.
