Presentemente, o controlo de gestão está vocacionado para agir antes de os factos indesejáveis ocorrerem, assegurando que os objectivos estabelecidos pela gestão são atingidos dentro do timing fixado. Além disso, o controlo de gestão deve ser o motor que permita alcançar as melhores performances nas áreas críticas da empresa, não só no domínio económico e financeiro, mas também nas áreas do crescimento, segurança e produtividade. Um dos mais importantes objectos das administrações actuais, é determinar se o desempenho da organização está de acordo com o que foi estabelecido previamente, ou seja, seus objectivos e metas. O meio através do qual se verificaria este desempenho seria a utilização de métodos e sistemas de avaliação de desempenho eficazes. Neste contexto, o presente estudo consiste em fazer um estudo exploratório descritivo identificando e averiguando de que forma as instituições bancárias de Cabo Verde efectuam a gestão de alguns aspectos, especialmente a avaliação de desempenho e o controlo estratégico, e que indicadores utilizam. Não obstante os objectivos específicos do trabalho serem outros, também damos especial atenção às características do mercado cabo-verdiano e à importância do sector bancário para a economia. Finalmente, apresentamos o Balanced Scorecard como uma ferramenta capaz de suprir as dificuldades da avaliação de desempenho e o conjunto de indicadores que vemos como o mais adequado. Neste ponto, concentramos nas quatro perspectivas básicas e no mapa estratégico, referindo o papel do Balanced Scorecard no alinhamento estratégico e na avaliação do desempenho organizacional. Para concluir, reforçamos o estudo, entrevistando um especialista (Director Financeiro) de um dos bancos da praça, cujo nome prometemos não publicar. Dessa forma, esperamos contribuir para uma melhor percepção da realidade em estudo, tanto do ponto de vista teórico, quanto da verificação das práticas no sector. Presently, the management control is oriented to act before the undesirable facts happen, assuring that the management established objectives are being achieved in the fixed timing. Besides, the management control must be an engine that permits to achieve the best performances at critical company areas, not only in the economic and financial areas, but at the growth, security and productivity areas too. One of the most important administration objects nowadays is to know if the organization performance is according to the fixed targets. The performance measurement could be done through effective methods and performance measurement systems. That’s why this assignment consists in doing an exploratory and descriptive study, identifying and investigating how the bank institutions of Cape Verde manage some things, particularly the performance measurement and the strategic control, and to know which indicators they use. Although the specific objectives of this assignment are others, we also give special attention to the Capeverdean market characteristics, and to the relevance of the banking industry to the economy of the country. Finally, we present the Balanced Scorecard as a competent tool to supply the measurement performance difficulties and a number of indicators that we find appropriate. In this point, we focus in the four basic perspectives and the strategic map, referring to the role of the Balanced Scorecard in the strategic alignment and organization performance measurement. We conclude this study with an interview to an expert (A Financial Manager) of a bank working in Cape Verde, whose name we promise to preserve. In this way, we hope to contribute to a better perception of this reality, in the theoretical point-of-view as much as in the practical check of this industry’s labour.

Iterated Local Search has many of the desirable features of a metaheuristic: it is simple, easy to implement, robust, and highly effective. The essential idea of Iterated Local Search lies in focusing the search not on the full space of solutions but on a smaller subspace defined by the solutions that are locally optimal for a given optimization engine. The success of Iterated Local Search lies in the biased sampling of this set of local optima. How effective this approach turns out to be depends mainly on the choice of the local search, the perturbations, and the acceptance criterion. So far, in spite of its conceptual simplicity, it has lead to a number of state-of-the-art results without the use of too much problem-specific knowledge. But with further work so that the different modules are well adapted to the problem at hand, Iterated Local Search can often become a competitive or even state of the artalgorithm. The purpose of this review is both to give a detailed description of this metaheuristic and to show where it stands in terms of performance.

The MyHits web site (http://myhits.isb-sib.ch) is an integrated service dedicated to the analysis of protein sequences. Since its first description in 2004, both the user interface and the back end of the server were improved. A number of tools (e.g. MAFFT, Jacop, Dotlet, Jalview, ESTScan) were added or updated to improve the usability of the service. The MySQL schema and its associated API were revamped and the database engine (HitKeeper) was separated from the web interface. This paper summarizes the current status of the server, with an emphasis on the new services.

We study a dynamic general equilibrium model where innovation takes theform of the introduction of new goods whose production requires skilled workers.Innovation is followed by a costly process of standardization, whereby these newgoods are adapted to be produced using unskilled labor. Our framework highlightsa number of novel results. First, standardization is both an engine of growth anda potential barrier to it. As a result, growth is an inverse U-shaped function ofthe standardization rate (and of competition). Second, we characterize the growthand welfare maximizing speed of standardization. We show how optimal protection of intellectual property rights affecting the cost of standardization vary withthe skill-endowment, the elasticity of substitution between goods and other parameters. Third, we show that, depending on how competition between innovatingand standardizing firms is modelled and on parameter values, a new type of multiplicity of equilibria may arise. Finally, we study the implications of our model forthe skill-premium and we illustrate novel reasons for linking North-South trade tointellectual property rights protection.

Latin America participated in the electric revolution which profoundly transformed the most developed Western economies between 1880 and 1930. The electrification of Latin America began relatively soon after these economies, but it was incapable of keeping up with them. Public electric lighting was introduced early in the big Latin American cities, where electric trams started running at almost the same time as in Europe, and electricity spread rapidly in the mining sector. In the most advanced countries or areas in the region, the manufacturing industry substituted the steam engine with the electric motor, following the example of industry in the United States and Europe. Nevertheless, towards 1930 electricity consumption per inhabitant for Latin America was far below that of the more advanced economies, and only the Latin American countries which lead the process of electrification had reached levels of electric consumption that were similar to those of the late industrialised European countries. One of the most striking features of the electric revolution in Latin America is rooted precisely in the enormous national differences. These differences are indicative of the great economic inequalities existing in the heart of the region and these nations highly diverse capacity for economic modernisation.

O presente trabalho visa estudar a importância de transformar os eventos culturais da ilha de São Vicente em produtos turísticos. Está mais do que provado que o turismo pode ser considerado o motor de desenvolvimento de qualquer economia, mas também que poderá levar a sérios problemas ambientais, sociais, culturais e até mesmo económicos com efeito a longo prazo, caso não for bem planeado. Dentro do turismo, o sector de eventos tem apresentado uma grande evolução, trazendo muitos benefícios e promoção para os destinos turísticos. Para além da importância que os eventos têm para os destinos turísticos, esta pesquisa também estudará o que é preciso ser feito a nível social, e em relação às infra-estruturas e serviços locais para serem transformados em produtos turísticos. Para efectuar essa transformação que poderá trazer muito mais benefícios tanto para a ilha como para a população local, será preciso que os eventos culturais da ilha sejam planeados e organizados, envolvendo todas as enti dades locais e a comunidade, de forma que possam criar soluções para desenvolver um turismo sustentável para São Vicente, e diminuir os impactos negativos no ambiente, na sociedade e na cultura. The goal of this Project is to study the importance of transforming the cultural events of São Vicente Island into touristic products. It is proved that tourism can be considered the development engine of any economy, but it can also lead to serious environmental, social, cultural end even economical problems with long term effects in case of bad planning. Within tourism, the events sector has seen a great evolution, bringing many benefits such as promotion to touristic destinations. Further to the importance that the events have to the touristic destinations, this research will also study what needs to be done concerning society and in relation to infrastructures and local services to be transformed into touristic products. To make these transformations come to life, something which can bring much more benefits to the island as well as to the local population, the cultural events of the island need to be planned and organized involving all the local entities, and the community, in the creation of solutions to develop a sustainable tourism for São Vicente and diminish the negative impacts on the environment, society and culture.

The main goal of this research is to investigate how people with different cultural background differ in their interaction style and visual behavior on search engine results pages (SERP), more specifically between groups from the Middle Eastern region vs. Western Europe. We conducted a controlled eye-tracking experiment to explore and evaluate the visual behavior of Arabs and Spaniardusers when scanning through the first page of the search results in Google. Big differences can be observed in the 4 aspects studied: U.A.E. participants stayed on the SERPs for longer, they read more results and they read each snippet in a more complete way than Spaniards. In Spain, people tended to scan the SERP, reading less text on each snippet, and choose a result among the first top rankedones without hardly seeing those in bottom positions.

A extracção clandestina de areia, nas faixas costeiras e nos leitos das ribeiras, tem sido prática de muitos agregados familiares cabo-verdianos. Nas últimas décadas, a praia de Calhetona (Ilha de Santiago) foi um dos muitos locais que sofreram degradação ambiental significativa, devido à realização desta actividade sem quaisquer planos de extracção e de posterior recuperação das áreas degradadas. Este trabalho, através da conjugação de recolha de dados por inquérito, observação directa e pesquisa documental e bibliográfica, teve como objectivos a caracterização da comunidade (que habita no bairro de Ponta Calhetona) que se dedica à extracção de areia na praia de Calhetona, a descrição da dinâmica da actividade extractiva, a avaliação da percepção que a comunidade tem relativamente às consequências da sua actividade e a descrição do impacte ambiental resultante da extracção de areia. Da análise dos inquéritos, efectuados em Fevereiro de 2012, a 25 chefes de agregados familiares que efectuam a extracção de areia na praia de Calhetona, constata-se que estes são maioritariamente mulheres, predominantemente com idade compreendida entre os 40 e os 59 anos, domésticas, com baixa escolaridade, com famílias numerosas e/ou alargadas a seu cargo e dedicando-se à extração de areia à mais de 10 anos. Os inquiridos, face à situação de vulnerabilidade económica, à falta de emprego e à grande procura de areia para a construção civil, vêem nesta actividade uma fonte de rendimento. Contudo, o proveito obtido desta actividade difícil e potencialmente perigosa é reduzido. Quem efectivamente beneficia são os camionistas que compram a areia a quem procede à extracção e a vendem ao consumidor final pelo dobro do preço. Os inquiridos demonstram uma consciência generalizada dos diversos impactes ambientais negativos resultantes da sua actividade, mas alegam que a extracção de areia é uma das poucas alternativas existentes para providenciar o sustento dos seus agregados familiares. Com base na comparação do estado actual da praia de Calhetona com relatos de habitantes locais, relativos às características da mesma no passado, verifica-se que nos últimos 40-50 anos, desde que se iniciou a intensa extracção de areia nesta praia, o seu aspecto físico se degradou claramente. Essa degradação caracteriza-se principalmente pelo recuo da linha de costa, pela quase ausência de areia e pela salinização dos solos localizados nas proximidades da praia, para além dos consequentes impactes negativos sobre a desova das tartarugas e o turismo balnear.

Air transportation is a key contributor to Iowa’s economy. The Iowa Department of Transportation’s Office of Aviation developed this 2009 report to evaluate and analyze the uses and benefits of aviation in Iowa. The statewide economic impact study shows how aviation serves as an economic engine, documents various ways air transportation is used in Iowa, and discusses other benefits that air transportation supports. Aviation related economic benefits measured in this study fall into two categories. In one category, benefits are measured in terms of jobs, payroll, and annual economic activity that various aviation and air transportation groups support. In the other category, added efficiency that businesses realize from their use of aviation is estimated in terms of increased productivity. Many of the economic benefits identified in this study are associated with commercial and general aviation airports that serve communities throughout Iowa. Beyond the boundaries of the airports are other aviation related activities that also add significant value to Iowa’s economy. Both types of economic benefit are discussed in this summary report.

Farms to Fuel project will demonstrate technology to produce alternative renewable energy by combining cattle manure with organic industrial waste products in an anaerobic digester. The digester produces methane gas which fires an engine set to generate base load electricity. This would create environmental benefits by turning crop, livestock, and industrial waste into renewable energy in a sustainable and profitable way. Other benefits of the project include the production of a fertilizer that is more readily applicable to crops than in its raw form.

Amana Farms is using an anaerobic digestion, which is a two-stage digester that converts manure and other organic wastes into three valuable by-products: 1) Biogas – to fuel an engine/generator set to create electricity; 2) Biosolids - used as a livestock bedding material or as a soil amendment; 3) Liquid stream - will be applied as a low-odor fertilizer to growing crops. (see Business Plan appendix H) The methane biogas will be collected from the two stages of the anaerobic digestion vessel and used for fuel in the combined heat and power engine/generator sets. The engine/generator sets are natural gasfueled reciprocating engines modified to burn biogas. The electricity produced by the engine/generator sets will be used to offset on-farm power consumption and the excess power will be sold directly to Amana Society Service Company as a source of green power. The waste heat, in the form of hot water, will be collected from both the engine jacket liquid cooling system and from the engine exhaust (air) system. Approximately 30 to 60% of this waste heat will be used to heat the digester. The remaining waste heat will be used to heat other farm buildings and may provide heat for future use for drying corn or biosolids. The digester effluent will be pumped from the effluent pit at the end of the anaerobic digestion vessel to a manure solids separator. The mechanical manure separator will separate the effluent digested waste stream into solid and liquid fractions. The solids will be dewatered to approximately a 35% solid material. Some of the separated solids will be used by the farm for a livestock bedding replacement. The remaining separated solids may be sold to other farms for livestock bedding purposes or sold to after-markets, such as nurseries and composters for soil amendment material. The liquid from the manure separator, now with the majority of the large solids removed, will be pumped into the farm’s storage lagoon. A significant advantage of the effluent from the anaerobic digestion treatment process is that the viscosity of the effluent is such that the liquid effluent can now be pumped through an irrigation nozzle for field spreading.

Introduction & Objectives: Surgery remains the treatment of choice for localized renal cell neoplasia. While radical nephrectomy was long considered as gold standard, partial nephrectomy (PN) has widened its indications over the past twodecades and has shown oncological results equivalent to radical nephrectomy for small tumors. Moreover, it is considered superior to radical nephrectomy in terms of non-cancer related mortality. The role of negative surgical margin has been widely debated. Intraoperative frozen section analysis has been shown to be unreliable, expensive, time-consuming and not well correlated to final pathology. The goal of the present study was to assess the correlation of intraoperative exvivo ultrasonographic (US) evaluation of resection margin to definitive pathology in patients undergoing PN.Materials & Methods: An observational study was carried out in ours 2 institutions from February 2008 to October 2010. Patients undergoing PN for T1-T2 renal tumors were included. Ex vivo US evaluation was performed. Considering availability of US engine, not all consecutive eligible patients were included. PN was undertaken either by open surgery or laparoscopic access in a standardized technique. The "minimal healthy tissue margin" technique was applied. Once resected, the specimen was kept in a saline solution and US determination of tumor margins was performed. Sequential images were captured in order to evaluate the whole capsule.Results: Twenty-two patients (9 women, age 63±11 years[46-78]) were included in the present analysis. Open or laparoscopic PN was performed in 19 and 3 patients, respectively. Intraoperative ex-vivo US showed negative surgical margin in all cases except one, needing a complementary renal parenchyma resection. US duration ranged from 1 to 4 minutes, with a median time of 1 minute. Definitive histological analysis confirmed the presence of 3 angiomyolipoma, 15 clear cell carcinoma (11 pT1a,3 pT1b,1 pT2), 3 chromophobe carcinoma (1 pT1a,1 pT1b,1 pT2) and 1 pT1a type II papillary tumor. Mean tumor size was 3,4±2.1 cm [0,6-7,2]. Final pathology revealed R0 margins in all cases.Conclusions: Intraoperative ex-vivo US evaluation of resection margin in patients undergoing PN is feasible, time-efficient, well correlated to definitive pathological examination, and should be evaluated in further prospective trials.

In order to study the various health influencing parameters related to engineered nanoparticles as well as to soot emitted b diesel engines, there is an urgent need for appropriate sampling devices and methods for cell exposure studies that simulate the respiratory system and facilitate associated biological and toxicological tests. The objective of the present work was the further advancement of a Multiculture Exposure Chamber (MEC) into a dose-controlled system for efficient delivery of nanoparticles to cells. It was validated with various types of nanoparticles (diesel engine soot aggregates, engineered nanoparticles for various applications) and with state-of-the-art nanoparticle measurement instrumentation to assess the local deposition of nanoparticles on the cell cultures. The dose of nanoparticles to which cell cultures are being exposed was evaluated in the normal operation of the in vitro cell culture exposure chamber based on measurements of the size specific nanoparticle collection efficiency of a cell free device. The average efficiency in delivering nanoparticles in the MEC was approximately 82%. The nanoparticle deposition was demonstrated by Transmission Electron Microscopy (TEM). Analysis and design of the MEC employs Computational Fluid Dynamics (CFD) and true to geometry representations of nanoparticles with the aim to assess the uniformity of nanoparticle deposition among the culture wells. Final testing of the dose-controlled cell exposure system was performed by exposing A549 lung cell cultures to fluorescently labeled nanoparticles. Delivery of aerosolized nanoparticles was demonstrated by visualization of the nanoparticle fluorescence in the cell cultures following exposure. Also monitored was the potential of the aerosolized nanoparticles to generate reactive oxygen species (ROS) (e.g. free radicals and peroxides generation), thus expressing the oxidative stress of the cells which can cause extensive cellular damage or damage on DNA.

When a material fails under a number of repeated loads, each smaller than the ultimate static strength, a fatigue failure is said to have taken place. Many studies have been made to characterize the fatigue behavior of various engineering materials. The results of some of these studies have proved invaluable in the evaluation and prediction of the fatigue strength of structural materials. Considerable time and effort has gone into the evaluation of the fatigue behavior of metals. These early studies were motivated by practical considerations: The first fatigue tests were performed on materials that had been observed to fail after repeated loading of a magnitude less than that required for failure under the application of a single load. Mine-hoist chains, railway axles, and steam engine parts were among the first structural components to be recognized as exhibiting fatigue behavior. Since concrete is usually subjected to static loading rather than cyclic loading, need for knowledge of the fatigue behavior of concrete has lagged behind that of metals. One notable exception to this, however, is in the area of highway and airfield pavement design. Due to the fact that the fatigue behavior of concrete must be understood in the design of pavements and reinforced concrete bridges, highway engineers have provided the motivation for concrete fatigue studies since the 1920's.
