It is understood organizations adopt practices about environment is essential, as their internal processes as external actions, the corporative and social changes are considered in this scene. It is observed consumers are important, therefore, more and more they analyze the responsible performance of Brazilian organizations. It was performed a quantitative research through questionnaire for achieving the objectives of this study. The sample was composed by 336 people at capacity consumption fully. The survey results demonstrate environmental management can be an excellent tool for conquering consumers, because consumers realize the great responsibility assumed by organizations regarding to the environment, nowadays. This finding was possible because most of the respondents answered the environmentally responsible behavior of organizations is decisive factor at the purchase’s moment. However, the data revealed consumers do not realize the practices adopted by companies. This lack of awareness may prejudice environmentally responsible organizations’ worth by consumers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20management" title="environmental management">environmental management</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=conscious%20consumption" title=" conscious consumption"> conscious consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazilian%20organizations" title=" Brazilian organizations"> Brazilian organizations</a> </p> <a href="https://publications.waset.org/abstracts/29440/the-consumers-attitudes-in-front-of-organizations-environmental-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29440.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">619</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> Interorganizational Relationships in the Brazilian Milk Production Chain </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20T.%20Okano">Marcelo T.

The interorganizational networks are important in economic life, the fact facilitate the complex interdependence between transactional and cooperative organizations. A need identified in the literature is the lack of indicators to measure and identify the types of existing networks. The objective of this research is to examine the interorganizational relationships of two milk chains through indicators proposed by the theories of the four authors, characterizing them as network or not and what the benefits obtained by the chain organization. To achieve the objective of this work was carried out a survey of milk producers in two regions of the state of São Paulo. To collect the information needed for the analysis, exploratory research, qualitative nature was used. The research instrument of this work consists of a roadmap of semistructured interviews with open questions. Some of the answers were directed by the interviewer in the form of performance notes aimed at detecting the degree of importance, according to the perception of intensity to that regard. The results showed that interorganizational relationships are small and largely limited to the sale of milk or dairy cooperatives. These relationships relate only to trade relations between the owner and purchaser of milk. But when the producers are organized in associations or networks, interorganizational relationships and increase benefits for all participants in the network. The various visits and interviews in several dairy farms in the regions of São Pau-lo (indicated that the inter-relationships are small and largely limited to the sale of milk to cooperatives or dairy. These relationships refer only to trade relations between the owner and the purchaser of milk. But when the producers are organized in associations or networks, interorganizational relationships increase and bring benefits to all participants in the network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interorganizational%20networks" title="interorganizational networks">interorganizational networks</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20chain" title=" dairy chain"> dairy chain</a>, <a href="https://publications.waset.org/abstracts/search?q=interorganizational%20system" title=" interorganizational system"> interorganizational system</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C3%A3o%20Pau-lo" title=" São Pau-lo"> São Pau-lo</a> </p> <a href="https://publications.waset.org/abstracts/29228/interorganizational-relationships-in-the-brazilian-milk-production-chain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29228.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">580</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Proposal for a Framework for Teaching Entrepreneurship and Innovation Using the Methods and Current Methodologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20T.%20Okano">Marcelo T.

The educational institutions such as universities, colleges and colleges of technology, has two main roles in this process, to guide and train entrepreneurs and provide technological knowledge and encourage innovation. Thus there was completing the triple helix model of innovation with universities, government and industry. But the teaching of entrepreneurship and innovation can not be only the traditional model, with blackboard, chalk and classroom. The new methods and methodologies such as Canvas, elevator pitching, design thinking, etc. require students to get involved and to experience the simulations of business, expressing their ideas and discussing them. The objective of this research project is to identify the main methods and methodologies used for the teaching of entrepreneurship and innovation, to propose a framework, test it and make a case study. To achieve the objective of this research, firstly was a survey of the literature on the entrepreneurship and innovation, business modeling, business planning, Canvas business model, design thinking and other subjects about the themes. Secondly, we developed the framework for teaching entrepreneurship and innovation based on bibliographic research. Thirdly, we tested the framework in a higher education class IT management for a semester. Finally, we detail the results in the case study in a course of IT management. As important results we improve the level of understanding and business administration students, allowing them to manage own affairs. Methods such as canvas and business plan helped students to plan and shape the ideas and business. Pitching for entrepreneurs and investors in the market brought a reality for students. The prototype allowed the company groups develop their projects. The proposed framework allows entrepreneurship education and innovation can leave the classroom, bring the reality of business roundtables to university relying on investors and real entrepreneurs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=Canvas" title=" Canvas"> Canvas</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20model" title=" traditional model"> traditional model</a> </p> <a href="https://publications.waset.org/abstracts/28907/proposal-for-a-framework-for-teaching-entrepreneurship-and-innovation-using-the-methods-and-current-methodologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28907.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">576</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Teaching of Entrepreneurship and Innovation in Brazilian Universities </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20T.%20Okano">Marcelo T.

Entrepreneurship is as important in small and medium-sized enterprises (SMEs) and local markets as in large companies, and national and international markets, and is just as key a consideration for public companies as or private organizations. Entrepreneurship helps to encourage the competition in the current environment that leads to the effects of globalization. There is an increasing tendency for government policy to promote entrepreneurship for its apparent economic benefit. Accordingly, governments seek to employ entrepreneurship education as a means to stimulate increased levels of economic activity. Entrepreneurship education and training (EET) is growing rapidly in universities and colleges throughout the world, and governments are supporting it both directly and through funding major investments in advice-provision to would-be entrepreneurs and existing small businesses. The Triple Helix of university–industry–government relations is compared with alternative models for explaining the current research system in its social contexts. Communications and negotiations between institutional partners generate an overlay that increasingly reorganizes the underlying arrangements. To achieve the objective of this research was a survey of the literature on the entrepreneurship and innovation and then a field research with 100 students of Fatec. To collect the data needed for analysis, we used the exploratory research of a qualitative nature. We asked to respondents what degree of knowledge over ten related to entrepreneurship and innovation topics, responses were answered in a Likert scale with 4 levels, none, small, medium and large. We can conclude that the terms such as entrepreneurship and innovation are known by most students because the university propagates them across disciplines, lectures, and institutes innovation. The more specific items such as canvas and Design thinking model are unknown by most respondents. The importance of the University in teaching innovation and entrepreneurship in the transmission of this knowledge to the students in order to equalize the knowledge. As a future project, these items will be re-evaluated to create indicators for measuring the knowledge level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brazilian%20universities" title="Brazilian universities">Brazilian universities</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title=" entrepreneurship"> entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title=" entrepreneurship"> entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=globalization" title=" globalization "> globalization </a> </p> <a href="https://publications.waset.org/abstracts/29234/teaching-of-entrepreneurship-and-innovation-in-brazilian-universities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29234.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">507</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">61</span> Translating History in a Brazilian Graphic Novel: A Translation Project for Angola Janga by Marcelo D'Salete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Rezende">Carolina Rezende</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Cesar%20Neves%20Monteiro"> Julio Cesar Neves Monteiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditionally, History and fiction are considered to be opposing fields of study. While one is linked to the study of facts, things that have happened within the limits of ‘reality’, the other explores a made-up world, originated from imagination and fantasy. However, despite their apparent discrepancies, there is a fundamental trait that brings them closer. Historical narratives, similarly to fiction ones, are produced based on multiple interpretations of an event, which are transmitted in a rather subjective way by language. It is within this perspective of history and fiction intertwined that this paper aims to discuss the translation of historical facts in the graphic novel Angola Janga, by Marcelo D’Salete, as well as presenting it as a historical document. The novel, which is divided into 11 short stories, narrates the rebellions that took place in Serra da Barriga, between the 16th and 17th centuries, that resulted in the Guerra dos Palmares. The graphic novel in question is a result of the author’s 11-year historical and bibliographical research, which combines history and fiction in order to shed a light of the confrontation that history seems to overlook. Also, the book includes a foreword, glossary, chronological line of Guerra dos Palmares, as well as maps and references used by the author during his research. For that, a few segments from the book will be selected and translated in order to show such connection between history and fiction, and the discussion resulted from it will be based on the works of Southgate (2009), Pym (2001) and D’hulst (2001). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphic%20novel" title="graphic novel">graphic novel</a>, <a href="https://publications.waset.org/abstracts/search?q=history" title=" history"> history</a>, <a href="https://publications.waset.org/abstracts/search?q=fiction" title=" fiction"> fiction</a>, <a href="https://publications.waset.org/abstracts/search?q=Palmares" title=" Palmares"> Palmares</a> </p> <a href="https://publications.waset.org/abstracts/100900/translating-history-in-a-brazilian-graphic-novel-a-translation-project-for-angola-janga-by-marcelo-dsalete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100900.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Towards Positive Identity Construction for Japanese Non-Native English Language Teachers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yumi%20Okano">Yumi Okano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The low level of English proficiency among Japanese people has been a problem for a long time. Japanese non-native English language teachers, under social or ideological constraints, feel a gap between government policy and their language proficiency and cannot maintain high self-esteem. This paper focuses on current Japanese policies and the social context in which teachers are placed and examines the measures necessary for their positive identity formation from a macro-meso-micro perspective. Some suggestions for achieving this are: 1) Teachers should free themselves from the idea of native speakers and embrace local needs and accents, 2) Teachers should be involved in student discussions as facilitators and individuals so that they can be good role models for their students, and 3) Teachers should invest in their classrooms. 4) Guidelines and training should be provided to help teachers gain confidence. In addition to reducing the workload to make more time available, 5) expanding opportunities for investment outside the classroom into the real world is necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=language%20teacher%20identity" title="language teacher identity">language teacher identity</a>, <a href="https://publications.waset.org/abstracts/search?q=native%20speakers" title=" native speakers"> native speakers</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20policy" title=" government policy"> government policy</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20pedagogy" title=" critical pedagogy"> critical pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=investment" title=" investment"> investment</a> </p> <a href="https://publications.waset.org/abstracts/164078/towards-positive-identity-construction-for-japanese-non-native-english-language-teachers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164078.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">103</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Study of Cahn-Hilliard Equation to Simulate Phase Separation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nara%20Guimar%C3%A3es">Nara Guimarães</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Aquino%20Martorano"> Marcelo Aquino Martorano</a>, <a href="https://publications.waset.org/abstracts/search?q=Douglas%20Gouv%C3%AAa"> Douglas Gouvêa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An investigation into Cahn-Hilliard equation was carried out through numerical simulation to identify a possible phase separation for one and two dimensional domains.

We develop a class of dynamic stochastic general equilibrium (DSGE) model with nominal rigidities and compare two de facto inflation stabilization policies, optimal monetary policy and optimal monetary and fiscal policy with the minimizing interest rate spread policy which completely suppress the default. Under the optimal monetary and fiscal policy, not only the nominal interest rate but also the tax rate work to minimize welfare costs through stabilizing inflation. Under the optimal monetary both inflation and output gap are completely stabilized although those are fluctuating under the optimal monetary policy. In addition, volatility in the default rate under the optimal monetary policy is considerably lower than one under the optimal monetary policy. Thus, there is not the SI-SD trade-off. In addition, while the minimizing interest rate spread policy makes inflation rate severely volatile, the optimal monetary and fiscal policy stabilize both the inflation and the default. A trade-off between stabilizing inflation and suppressing default is not so severe what pointed out by Uribe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sovereign%20risk" title="sovereign risk">sovereign risk</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20monetary%20policy" title=" optimal monetary policy"> optimal monetary policy</a>, <a href="https://publications.waset.org/abstracts/search?q=fiscal%20theory%20of%20the%20price%20level" title=" fiscal theory of the price level"> fiscal theory of the price level</a>, <a href="https://publications.waset.org/abstracts/search?q=DSGE" title=" DSGE"> DSGE</a> </p> <a href="https://publications.waset.org/abstracts/50808/revisiting-the-fiscal-theory-of-sovereign-risk-from-the-dsge-view" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50808.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">321</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Non–Geometric Sensitivities Using the Adjoint Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Hayashi">Marcelo Hayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Lima"> João Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Chieregatti"> Bruno Chieregatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ernani%20Volpe"> Ernani Volpe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The adjoint method has been used as a successful tool to obtain sensitivity gradients in aerodynamic design and optimisation for many years.

Many companies use the techniques of the Toyota Production System, which in a way goes against a better management of supply chain risks. This paper studies key events in some multinationals to analyze the trade-off between the best supply chain risk management techniques and management policies designed to create lean enterprises. The result of a good balance of these actions is the reduction of losses, increased customer trust in the company and better preparedness to face the general risks of a supply chain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=just%20in%20time" title="just in time">just in time</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title=" lean manufacturing"> lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20disruptions" title=" supply chain disruptions"> supply chain disruptions</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a> </p> <a href="https://publications.waset.org/abstracts/51640/analysis-of-supply-chain-risk-management-strategies-case-study-of-supply-chain-disruptions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51640.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">338</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Association of Social Data as a Tool to Support Government Decision Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Rodrigues">Diego Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Lisboa"> Marcelo Lisboa</a>, <a href="https://publications.waset.org/abstracts/search?q=Elismar%20Batista"> Elismar Batista</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcos%20Dias"> Marcos Dias </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on data on child labor, this work arises questions about how to understand and locate the factors that make up the child labor rates, and which properties are important to analyze these cases.

Therefore, modulating neuronal activity in these regions may change individuals’ perception in a given situation such as exercise. We tested whether transcranial direct current stimulation (tDCS) change cerebral oxygenation and pleasure during exercise. Fourteen volunteer healthy adult men were assessed into five different sessions. First, subjects underwent to a maximum incremental test on a cycle ergometer. Then, subjects were randomly assigned to a transcranial direct current stimulation (2mA for 15 min) intervention in a cross over design in four different conditions: anode and cathode electrodes on T3 and Fp2 targeting the insular cortex, and Fpz and F4 targeting prefrontal cortex, respectively; and their respective sham. These sessions were followed by 30 min of moderate intensity exercise. Brain oxygenation was measured in prefrontal cortex with a near infrared spectroscopy. Perceived exertion and pleasure were also measured during exercise. The asymmetry in prefrontal cortex oxygenation before the stimulation decreased only when it was applied over this region which did not occur after insular cortex or sham stimulation. Furthermore, pleasure was maintained during exercise only after prefrontal cortex stimulation (P > 0.7), while there was a decrease throughout exercise (P < 0.03) during the other conditions. We conclude that tDCS over the prefrontal cortex changes brain oxygenation in ventromedial prefrontal cortex and maintains perceived pleasure during exercise. Therefore, this technique might be used to enhance effective responses related to exercise. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=affect" title="affect">affect</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20stimulation" title=" brain stimulation"> brain stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=dopamine%20neuromodulation" title=" dopamine neuromodulation"> dopamine neuromodulation</a>, <a href="https://publications.waset.org/abstracts/search?q=pleasure" title=" pleasure"> pleasure</a>, <a href="https://publications.waset.org/abstracts/search?q=reward" title=" reward"> reward</a>, <a href="https://publications.waset.org/abstracts/search?q=transcranial%20direct%20current%20stimulation" title=" transcranial direct current stimulation"> transcranial direct current stimulation</a> </p> <a href="https://publications.waset.org/abstracts/75181/the-effects-of-transcranial-direct-current-stimulation-on-brain-oxygenation-and-pleasure-during-exercise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75181.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">326</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Independent Audit in Brazilian Companies Listed on B3: An Analysis of Companies That Received Qualified Opinion and Disclaimer of Opinion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Saldo%20Alves">Diego Saldo Alves</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Paveck%20Ayub"> Marcelo Paveck Ayub</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The quality of accounting information is very important for the decision-making of managers, investors government and other information users.

Batch scale tests were carried out at pH range of 2 to 7 using a laboratory solution simulating concentrate nickel liquors as those typically obtained when sulfate intermediates from nickel laterite are re-leached and treated for the selective removal of cobalt, zinc, manganese and copper with Cyanex 272 ([Ca] = 0.57 g/L, [Mg] = 3.2 g/L, and [Ni] = 88 g/L). The increase on the concentration of D2EHPA favored the calcium extraction. The extraction of magnesium is dependent on the pH and of ratio of extractants D2EHPA and Cyanex 272 in the organic phase. The composition of the investigated organic phase did not affect nickel extraction. The number of stages is dependent on the magnesium extraction.

Market-based and labor environment explanations have received particular attention, both to explain the reasons for a growth in this compensation and to indicate that they may increase agency problems rather than mitigate them. In this sense, labor forces, especially related to the market for executives, contribute to defining the terms of compensation packages and represent a significant external control mechanism to moderate agency problems, but may be of little effect if the executives are entrenched and concentrate enough power to have a say in his/her compensation. Based on a five-year data panel related to executive compensation in 250 listed companies in Brazil, we examine whether the economic recession in the last two years produced any impact in this compensation, controlling for the sector and level of governance of the company. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agency%20problems" title="agency problems">agency problems</a>, <a href="https://publications.waset.org/abstracts/search?q=executive%20compensation" title=" executive compensation"> executive compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20mechanisms" title=" control mechanisms"> control mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title=" corporate governance"> corporate governance</a> </p> <a href="https://publications.waset.org/abstracts/81769/effects-of-an-economic-recession-on-executive-compensation-a-panel-analysis-of-listed-companies-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81769.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">445</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Determinant Elements for Useful Life in Airports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20M%C3%BCller%20Beuren">Marcelo Müller Beuren</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Duarte%20Ribeiro"> José Luis Duarte Ribeiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies point that Brazilian large airports are not managing their assets efficiently. Therefore, organizations seek improvements to raise their asset’s productivity. Hence, identification of assets useful life in airports becomes an important subject, since its accuracy leads to better maintenance plans and technological substitution, contribution to airport services management. However, current useful life prediction models do not converge in terms of determinant elements used, as they are particular to the studied situation. For that reason, the main objective of this paper is to identify the determinant elements for a useful life of major assets in airports. With that purpose, a case study was held in the key airport of the south of Brazil trough historical data analysis and specialist interview. This paper concluded that most of the assets useful life are determined by technical elements, maintenance cost, and operational costs, while few presented influence of technological obsolescence. As a highlight, it was possible to identify the determinant elements to be considered by a model which objective is to identify the useful life of airport’s major assets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airports" title="airports">airports</a>, <a href="https://publications.waset.org/abstracts/search?q=asset%20management" title=" asset management"> asset management</a>, <a href="https://publications.waset.org/abstracts/search?q=asset%20useful%20life" title=" asset useful life"> asset useful life</a> </p> <a href="https://publications.waset.org/abstracts/24890/determinant-elements-for-useful-life-in-airports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24890.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">522</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> A Method for Reduction of Association Rules in Data Mining</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20De%20Castro%20Rodrigues">Diego De Castro Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Lisboa%20Rocha"> Marcelo Lisboa Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20M.%20De%20Q.%20Trevisan"> Daniela M.

Very often, the number of rules generated is high, sometimes even in databases with small volume, so the success in the analysis of results can be hampered by this quantity. The purpose of this research is to present a method for reducing the quantity of rules generated with association algorithms. Therefore, a computational algorithm was developed with the use of a Weka Application Programming Interface, which allows the execution of the method on different types of databases. After the development, tests were carried out on three types of databases: synthetic, model, and real. Efficient results were obtained in reducing the number of rules, where the worst case presented a gain of more than 50%, considering the concepts of support, confidence, and lift as measures. This study concluded that the proposed model is feasible and quite interesting, contributing to the analysis of the results of association rules generated from the use of algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title="data mining">data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=association%20rules" title=" association rules"> association rules</a>, <a href="https://publications.waset.org/abstracts/search?q=rules%20reduction" title=" rules reduction"> rules reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a> </p> <a href="https://publications.waset.org/abstracts/110517/a-method-for-reduction-of-association-rules-in-data-mining" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110517.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Finite Element Analysis of the Blanking and Stamping Processes of Nuclear Fuel Spacer Grids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Oliveira%20Santos">Rafael Oliveira Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Pessanha%20Moreira"> Luciano Pessanha Moreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Costa%20Cardoso"> Marcelo Costa Cardoso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spacer grid assembly supporting the nuclear fuel rods is an important concern in the design of structural components of a Pressurized Water Reactor (PWR).

The use of a magnetic organic liquid (also known as ferrofluid), consisting of magnetite nanoparticles coated by oleic acid dispersed in the organic diluent, has proven successful to speed up phase disengagement. The method, however, has never been used industrially; therefore, the aim of this study is to raise its main limitations. Tests were carried out using a ferrofluid containing 30 g/l of magnetite dissolved in commercial aliphatic kerosene Exxsol D80. The efficiency of cobalt extraction ([Co] = 1 g/l) with 10% v/v Cyanex 272 (bis-2,4,4-trimethylpentyl phosphinic acid) at changing pH of the aqueous phase (2 to 7) was found unaffected in the conditions studied. However, the chemical resistance of the ferrofluid in contact with deionized water at changing acidity (from 10-7 to 2 mol/l) revealed that the nanoparticles are not resistant when contacted to aqueous solutions with a pH ≤ 2. Such result represents a serious limitation to the applicability of the method mainly to hydrometallurgical systems because solvent extraction operations are normally done in acid conditions, therefore more effective strategies to coat the particles are required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20solvent%20extraction" title="magnetic solvent extraction">magnetic solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=oleic%20acid" title=" oleic acid"> oleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetite%20nanoparticles" title=" magnetite nanoparticles"> magnetite nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=cyanex%20272" title=" cyanex 272"> cyanex 272</a> </p> <a href="https://publications.waset.org/abstracts/41603/magnetic-solvent-extraction-using-nanoparticles-coated-by-oleic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41603.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Water Detection in Aerial Images Using Fuzzy Sets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caio%20Marcelo%20Nunes">Caio Marcelo Nunes</a>, <a href="https://publications.waset.org/abstracts/search?q=Anderson%20da%20Silva%20Soares"> Anderson da Silva Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Gustavo%20Teodoro%20Laureano"> Gustavo Teodoro Laureano</a>, <a href="https://publications.waset.org/abstracts/search?q=Clarimar%20Jose%20Coelho"> Clarimar Jose Coelho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a methodology to pixel recognition in aerial images using fuzzy $c$-means algorithm.

However, in the real world there are many areas with uncertainties and inaccuracies which can be mapped by clustering algorithms that use fuzzy sets. The methodology presents in this work is applied to multispectral images obtained from Landsat-5/TM satellite. The pixels are joined using the $c$-means algorithm. After, a classification process identify the types of surface according the patterns obtained from spectral response of image surface. The classes considered are, exposed soil, moist soil, vegetation, turbid water and clean water. The results obtained shows that the fuzzy clustering identify the real type of the earth's surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerial%20images" title="aerial images">aerial images</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20clustering" title=" fuzzy clustering"> fuzzy clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition" title=" pattern recognition"> pattern recognition</a> </p> <a href="https://publications.waset.org/abstracts/30574/water-detection-in-aerial-images-using-fuzzy-sets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30574.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">482</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Helping the Development of Public Policies with Knowledge of Criminal Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20De%20Castro%20Rodrigues">Diego De Castro Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20B.%20Nery"> Marcelo B.

Therefore, it has been noticed that monitoring of meteorological data (solar irradiance, air temperature, wind velocity, etc.) is important to predict the potential of a given geographical area in solar energy production. In this sense, the present work compares two computational tools that are capable of estimating the energy generation of a photovoltaic system through correlation analyzes of solar radiation data: PVsyst software and an algorithm based on the PVlib package implemented in MATLAB. In order to achieve the objective, it was necessary to obtain solar radiation data (measured and from a solarimetric database), analyze the decomposition of global solar irradiance in direct normal and horizontal diffuse components, as well as analyze the modeling of the devices of a photovoltaic system (solar modules and inverters) for energy production calculations. Simulated results were compared with experimental data in order to evaluate the performance of the studied methods. Errors in estimation of energy production were less than 30% for the MATLAB algorithm and less than 20% for the PVsyst software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20production" title="energy production">energy production</a>, <a href="https://publications.waset.org/abstracts/search?q=meteorological%20data" title=" meteorological data"> meteorological data</a>, <a href="https://publications.waset.org/abstracts/search?q=irradiance%20decomposition" title=" irradiance decomposition"> irradiance decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20photovoltaic%20system" title=" solar photovoltaic system"> solar photovoltaic system</a> </p> <a href="https://publications.waset.org/abstracts/101500/comparison-of-irradiance-decomposition-and-energy-production-methods-in-a-solar-photovoltaic-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101500.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Effects of Voltage Pulse Characteristics on Some Performance Parameters of LiₓCoO₂-based Resistive Switching Memory Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Van%20Son%20Nguyen">Van Son Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Huy%20Mai"> Van Huy Mai</a>, <a href="https://publications.waset.org/abstracts/search?q=Alec%20Moradpour"> Alec Moradpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Auban%20Senzier"> Pascale Auban Senzier</a>, <a href="https://publications.waset.org/abstracts/search?q=Claude%20Pasquier"> Claude Pasquier</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang%20Wang"> Kang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre-Antoine%20Albouy"> Pierre-Antoine Albouy</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20J.%20Rozenberg"> Marcelo J.

Both data on morphological aspects of the newly-formed tissue, and clinical trials comparing different templates, are still lacking. The goal of this study was to prospectively analyze the outcome of patients treated with two of the existing templates, followed by thin skin autograft. They are both made of bovine collagen, one includes a superficial silicone layer. Surgery was performed on patients with impaired mobility resulting from burn sequelae (n = 12 per template). Negative pressure therapy was applied post-surgically; patients were monitored for 12 months. Data on scar skin quality (Vancouver and POSAS evaluation scales), rate of joint mobility recovery, and graft contraction were recorded. Improvement in mobility and skin quality were demonstrated along with graft contraction, in all patients. The silicone-coupled template showed the best performance in all aspects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dermal%20regeneration%20template" title="dermal regeneration template">dermal regeneration template</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20skin" title=" artificial skin"> artificial skin</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20quality" title=" skin quality"> skin quality</a>, <a href="https://publications.waset.org/abstracts/search?q=scar%20contracture" title=" scar contracture"> scar contracture</a> </p> <a href="https://publications.waset.org/abstracts/103937/comparative-study-of-dermal-regeneration-template-made-by-bovine-collagen-with-and-without-silicone-layer-in-the-treatment-of-post-burn-contracture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103937.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Numerical Analysis of Crack's Effects in a Dissimilar Welded Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20N.%20L.%20Alves">Daniel N.

As soon, to understand the response of materials when submitted to adverse conditions is essential to design a safety project. This work investigates the presence of cracks in dissimilar welded joints (DWJ). Its fracture toughness responses depend upon the heterogeneity present in these joints. Thus, this work aim analyzing the behavior of the crack tip zone located in a buttery dissimilar welded joint (ASTM A-36, Inconel, and AISI 8630 M) used in the union of pipes present in the offshore oil production lines. The crack was placed 1 mm from fusion line (FL) Inconel-AISI 8630 M toward the AISI 8630 M. Finite Element Method (FEM) was used to analyze stress and strain fields generated during the loading imposed on the specimen. It was possible observing critical stress area by the numerical tool as well as a preferential plastic flow was also observed in the sample of dissimilar welded joint, which can be considered a harbinger of the crack growth path. The results obtained through numerical analysis showed a convergent behavior in relation to the plastic flow, qualitatively and quantitatively, in agreement with previous performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack" title="crack">crack</a>, <a href="https://publications.waset.org/abstracts/search?q=dissimilar%20welded%20joint" title=" dissimilar welded joint"> dissimilar welded joint</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20field" title=" strain field"> strain field</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20stress%20field" title=" the stress field"> the stress field</a> </p> <a href="https://publications.waset.org/abstracts/88025/numerical-analysis-of-cracks-effects-in-a-dissimilar-welded-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88025.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Digital Transformation: The Effect of Artificial Intelligence on the Efficiency of Financial Administrative Workers in Peru in 2024</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Fabrizio%20Gavilano%20Farje">Thiago Fabrizio Gavilano Farje</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Patricio%20Herrera%20Malpartida"> Marcelo Patricio Herrera Malpartida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the influence of artificial intelligence (AI) on the work efficiency of administrative employees in the financial sector of Metropolitan Lima, Peru, during the year 2024. Focusing on the relationship between AI implementation and work efficiency, it addresses specific variables such as decision-making, motivation, and employee productivity. To accomplish the analysis between AI and work efficiency within the financial sector of Metropolitan Lima, it is necessary to evaluate how AI optimizes time in administrative tasks, examine how AI impacts the agility of the process of making decisions, and investigate the influence of AI on the satisfaction and motivation of employees. The research adopts a correlational and explanatory approach, designed to establish and understand the connections between AI and work efficiency. A survey design adapted from an OECD study is used, applying questionnaires to a representative sample of administrative workers in the financial sector who incorporate AI into their functions. The target population includes administrative workers in the financial sector of Metropolitan Lima, estimated at 73,097 employees based on data from the Censo Nacional de Empresas y Establecimientos and studies by the BCRP. The sample, selected through simple random sampling, comprises 246 workers. <p class="card-text"><strong>Keywords:</strong> <a
