O Sistema Técnico-Democrático/The technical-democratic system
Authors: Silveira Ronie Alexsandro Teles da
Published: December 2019

Possuímos sentimentos divergentes com relação a aspectos do presente: somos otimistas com relação à expansão da democracia e cautelosos com relação à aplicação intensa da técnica. Indago se é possível manter esses dois sentimentos divergentes a partir de uma análise da situação cultural que produziu as noções atuais de natureza e sujeito – os respectivos fundamentos da técnica e da democracia contemporâneas. Constato que o sistema técnico-democrático, do qual essas noções emergiram, impõe uma conexão específica entre a natureza e o sujeito, de tal forma que o movimento produzido em uma delas afeta necessariamente a outra. Portanto, democracia e técnica se constituem como as duas faces de uma mesma moeda e não devem ser tratadas de maneira abstrata, como dois elementos distintos. As tentativas de identificação de problemas e de proposição de soluções sobre a técnica e a democracia tenderão a produzir resultados inócuos se partirem dessa perspectiva abstrata que os representa como dois elementos separados da vida contemporânea.Abstract: We have different feelings about aspects of the actual world: we are optimistic about the expansion of democracy and cautious about the technique’s intense application. I ask if it’s possible to keep these two conflicting feelings from an analysis of the cultural situation that produced the current notions of nature and subject – the respective foundations of contemporaries technique and democracy. I note the technical democratic system, which these notions have emerged, imposes a specific connection between nature and subject, such that the movement produced in one necessarily affects another. Therefore, democracy and technique constitute as two sides of the same coin and should not be treated abstractly as two distinct elements. Attempts to identify problems and propose solutions about the technique and democracy will tend to produce innocuous results if they start from this abstract point of view that represent them as two separate elements of contemporary life. Keywords: Technique; Democracy; Nature; Subjectivity; Technical Democratic System.
Técnica e Inteligência Artificial: O debate entre J. Searle e D. Dennett/Technique and Artificial intelligence: the debate between J. Searle and D. Dennett
Authors: Viana Wellistony Carvalho
Published: December 2019

O debate entre J. Searle e D. Dennett acerca da possibilidade técnica de uma Inteligência artificial gira em torno de uma única questão: estados mentais expressam algo intrínseco, privado e subjetivo, experimentado em primeira-pessoa ou não passam de entidades obscurantistas, frutos da ignorância e, em princípio, reduzíveis à objetividade científica da neurociência? Searle defende a primeira tese, enquanto Dennett argumenta pela segunda. O texto expõe a posição de Dennett, a crítica de Searle e se direciona para uma nova solução, que defende um monismo integral, no qual mente e cérebro podem ser vistos como duas dimensões de uma mesma realidade. Nesse sentido, o projeto de Inteligência artifical precisará revisar o conceito de “físico” se quiser avançar em suas pretenções, incluindo nele conceitos hoje antagônicos como intencionalidade, liberdade e subjetividade. Abstract: The debate between J. Searle and D. Dennett about the technical possibility of an artificial intelligence revolves around a single issue: mental states express something intrinsic, private and subjective, experienced in first-person or are merely obscurantist entities, results from ignorance and, in principle, reducible to scientific objectivity of neuroscience? Searle argues for the first position, while Dennett argues for the second. The text exposes the position of Dennett, the criticism of Searle and is directed to a new solution, which advocates an integral monism, in which mind and brain can be seen as two dimensions of the same reality. In this sense, the project of artificial intelligence need to review the concept of "physical" if it wants to advance its claims, including today antagonistic concepts such as intentionality, freedom and subjectivity. Keywords: physicalism, technique, artificial intelligence, John Searle, Daniel Dennett.
O Ethos democrático contemporâneo: das culturas tradicionais à fusão de culturas/The Contemporary Democratic Ethos: from Traditional Cultures to Fusion of Cultures
Authors: Danner Leno Francisco
Published: December 2019

O artigo defende que, desde a segunda metade do século XX, o processo de evolução de nossas sociedades é marcado pela acelerada fusão e pela cada vez mais intensa miscigenação de culturas, que apontam para o enfraquecimento das culturas e das instituições tradicionais por causa da constituição de uma nova cultura, fundida e miscigenada, afirmadora do pluralismo e do individualismo, bases para o universalismo moral. Além disso, nesse mesmo período, a crítica ao modelo de modernização ocidental (capitalismo, racionalização), que estaria destruindo formas alternativas de sociabilidade, de relação com o mundo e de produção da vida material, passou a dar a tônica da atuação de novos movimentos sociais, grupos culturais e iniciativas cidadãs. Com isso, é possível perceber-se um aspecto político-cultural altamente emancipatório em nossas sociedades, isto é, a desconstrução das culturas e da autoridade das instituições tradicionais, bem como a necessidade de repensar-se o modelo de progresso e de desenvolvimento ocidentais, em favor da democracia, dos direitos humanos e de formas alternativas de vida, o que aponta para uma reavaliação positiva, em termos de Ocidente e mesmo do Brasil, das culturas indígenas e negras para a formação das nossas sociedades e para a superação de seus problemas.Abstract: the paper argues that, since second half of twentieth century, the process of evolution of our societies is characterized by rapid fusion and very intense miscegenation of cultures, what points to impairment of traditional cultures and institutions, because the constitution of a new culture, fused and mixed, affirming pluralism and individualism that are the basis for moral universalism. Moreover, in this same period, the critic to the western model of modernization (capitalism, rationalization), that would be destroying alternative forms of sociability, relation with de world and production of material life, become current with new social movements, cultural groups and citizen initiatives. So, it is possible to perceive a highly emancipatory political-cultural aspect in our societies, namely the deconstruction of traditional cultures and authority of institutions, in favor of the democracy, human rights and alternative forms of life that conducts to a positive revaluation, in terms of Western and even Brazil, of indigenous and black cultures to the constitution of our societies and the overcoming of their social problems. Keywords: Democracy; Fusion of Cultures; Tradition; Modernization; Revaluation.
Uma concepção bidimensional de democracia como salvaguarda da liberdade/A two-dimensional design of democracy as a safeguard for freedom
Authors: Oliveira Joedson De Santana
Published: December 2019

Este trabalho tem o propósito de apresentar uma concepção republicana de democracia que não é uma democracia participativista nos moldes de Rousseau, que defendeu uma democracia direta, tampouco é uma democracia liberal que resume a participação ao sufrágio. Iremos argumentar que a democracia defendida dentro do republicanismo de Philip Pettit, entendida como democracia bidimensional, por ser ao mesmo tempo eleitoral e contestatória, é não só compatível com a defesa da liberdade, mas, também e, sobretudo, guardiã da mesma.Abstract: This paper aims to present a republican conception of democracy is not a democracy direct the lines of Rousseau, who argued for a direct democracy, nor is it a liberal democracy that summarizes the participation of suffrage. We will argue that democracy advocated in Philip Pettit's republicanism, democracy understood as two-dimensional, being at the same time and contestatory election, is not only compatible with the defense of freedom, but also and above all, the same guardian. Key words: Freedom; democracy; republicanism; Philip Pettit

Observaremos o que é específico de uma narrativa, no que diz respeito a sua ordem de composição como também sua efetivação pragmática a partir de uma metodologia demonstrativa por meio dos contos selecionados. Desta forma, desenvolveremos nosso propósito de investigação acerca do conceito em estudo. E, ainda, explicitar o conjunto das proposições que evidencia a construção do sentido expresso na relação constitutiva das ações quanto ao problema da compreensão do todo. Daí a necessidade da sistematização do conceito de intriga na narrativa de ficção.

Materials and methods. There were examined 1824 patients, suffering DFS for period from 2015 to 2019 yr., who suffered purulent-necrotic affections of the foot - abscess, phlegmon, purulent tendovaginitis, purulent arthritis, gangrene. All the patients suffered diabetes mellitus Type 2, average duration of which have constituted (12.3 ± 2.7) yrs. Qualitative content of microflora and sensitivity of cultures for antibiotics were revealed  on automatic microbiological analizators «Vitek2» and BacT/ALERT (France).
Results. The cause of purulent-necrotic complications was a gram-positive microflora, which in 57.1 - 66.8% patients was diagnosed in monoinfection and prevailed in a content of microbial associations. Phenomena of resistance to the main antibacterial preparations was revealed in 37.4% bacteria. The biggest resistance have had Staphylococcus aureus and Enterococcus faecalis. In 62.5% patients, owing Staphylococcus aureus, a resistance gene to Staphylococcus aureus with three genetic variations were revealed, which differed in accordance to resistance for certain groups of antibiotics. The most significant MRSA Type 3 - panresistant (in 6/2% patients).
Conclusion. Investigations of purulent-necrotic foci in patients with the DFS witnesses, that the leading microorganism while development of complications constitutes a gram-positive  microflora, which is characterized by presence of polyresistant and panresistant strains. Such a condition gives background to necessity for correcting of the antibacterial therapy administered.

Results of ultrasonographic investigation in 546 patients, ageing 17 - 76 old and suffering thyroidal nodal affections, were analyzed. All the patients were divided into two groups. Into the firsr group  (the main) 427 (78.2%) patients were included, to whom ultrasonographic investigation was performed by a surgeon-endocrinologist. Into the second group (the control one) 119 (21.8%) patients were included, to whom ultrasonographic investigation was performed by a radiologist. Ultrasonographic criteria with nodal thyroidal affections were estimated in accordance to the TI-RADS scale, and the results of cytological investigations of the nodal affections - in accordance to criteria of the Bethesda system. The degree of the malignant nodal affections risk was determined, taking into account a quantity of intranodal echographic signs in accordance to the points gradation, using a Ti-RADS system. Results. In accordance to results of pathohistological investigations of the removed specimen a benign changes were revealed in 128 (76.6%) patients, and malignant - in 39 (23.4%). In structure of malignant affections papillary cancer was established in 23 patients, follicular - in 13, medullary - in 2, Hurtle-cellular - in 1 patient. In accordance to cytological investigations, conducted in 2014 - 2018 yrs., there was established, that in the first group a fine-needle biopsy was conducted in 211/427(49.4%) patients. Operative interventions were performed in 105 (24.6%) patients. In the second group a fine-needle biopsy was performed in 64/119 (53.8%) patients. Operative intervention was conducted in 62 (52.1%) patients. Conclusion. While conduction of ultrasonographic investigation by a surgeon-endocrinologist the rate of revealing of false-positive echographic signs have lowered in more than 2 times (1.4%), comparing with analogous index while conduction of the investigation by radiologist (3.1%). Application of a TI-RADS classification have permitted to reduce the rate of the fine-needle biopsy and doing of surgical interventions.

Qualitative Analysis of the Relationship Between Teachers and Students`not-Knowing in the Process of Solving Reasoning Tasks
Authors: Fierro Kevin , Tchoshanov Mourat , Shakirova Gulshat
Published: December 2019

Mason and Spence’s (1999) work demonstrate a detailed view into the concept of knowing. Although they highlight the importance of not-knowing as a first step, it is a topic that is not well researched. This study aims at expanding that research, by analyzing not-knowing expressions from teacher to student and possible connections to be found. During a course of geometric reasoning student teachers were asked to reason with a tangram while simultaneously recording their expressions of not-knowing and reflecting on it periodically. Student teachers were then tasked to teach this lesson to their students, who would also reflect and express their forms of not-knowing. Findings presented no real link between teacher-student expressions of not-knowing, but two major conclusions were made. Individuals altogether struggle conveying their not-knowing clearly and when they did express it, these expressions leaned heavily on not-knowing-that and not-knowing-how forms. A discussion follows to interpret said findings. A conclusion is made detailing key points in the study and what comes next for the concept of not-knowing.

The problem is that: while in the beginning, kids are very enthusiastic about performing chores and collecting points, by the time when they have accumulated a sufficient number of points, they become less and less interested. In this paper, we provide a decision theory solution on how many points to assign for consecutive chores.

Education researchers often cite a statement from Anatole France: "An education isn't how much you have committed to memory, or even how much you know. It's being able to differentiate between what you know and what you don't." In this paper, we show how this statement can be transformed into an exact theorem.

In some classes, students want to get a passing grade (e.g., C or B) by spending the smallest amount of effort. In such situations, it is reasonable for the instructor to assign the grades for different tasks in such a way that the resulting overall student's effort is the largest possible. In this paper, we show that to achieve this goal, we need to assign, to each task, the number of points proportional to the efforts needed for this task.
The impact of inflation on the cost of adjustable-rate mortgages
Authors: Musiałowski Tomasz
Published: December 2019

Aim: To assess how inflation affects the cost of adjustable-rate mortgage from the perspective of personal finances.Design / Research methods: Adjustable-Rate Mortgage simulations were carried out, showing both the nominal and real costs of a mortgage loan. The behavior and the relationship between the inflation rate and WIBOR 3M rate were compared.Conclusions / findings: The analysis shows that the real cost of mortgage decreases with an increase in inflation. During the period under review, inflation declined, reducing both the real and nominal cost of the loan. There was a strong positive correlation between the WIBOR 3M rate and the inflation rate. Equally strong, although a negative correlation was observed between the inflation rate and the real interest rate. With the decline in inflation, real mortgage rates increased, and vice versa. Particular attention was paid to the periods in which inflation was rising. WIBOR 3M rate reacted to this increase to a much lesser extent and with a lag compared to the inflation rate.Originality / value of the article: Considering that forecasts presented by the National Bank of Poland predict inflation growth in the coming years, a thorough examination of the inflation impact on the mortgage costs is an important issue for risk management in households with mortgage.
The Islamic economy: its origin, its world view and its claims
Authors: Visser Hans
Published: December 2019

Aim: This article takes a critical look at the claims made by advocates of an Islamic economy, in particular that it differs fundamentally from capitalism and socialism because it is built “on a superior ethical basis. The aim is to find out whether this claim can be creditably sustained and why it is made.Design: The world view behind the Islamic economy is probed into by means of a literature study encompassing publications by prominent students of Islam and Islamic economics, predominantly themselves Muslims, which have appeared in a wide range of professional books, magazines and paper series.Conclusions: It is concluded that an Islamic economic system does not differ fundamentally from mixed-economy non-Islamic ones and that there is little reason for non-Muslims to accord Islamic ethics special status. Further, it is found that important drivers of the attempts to Islamize the economy are frustration about the sorrow state of the Islamic world at least since the early nineteenth century and a wish to regain something of its former glory. In other words, identity politics is at play. There may an element of subjectivity in this conclusion, as it depends on interpretations that are hard to prove or disprove conclusively, but statements by leading Muslim advocates of Islam economists give it weight. The conclusion may help to interpret developments in the Muslim world, which is an indispensable step in finding a way to deal with them.
The impact of foreign trade on the Netherlands’ real CO2 emissions
Authors: Fortuński Bartosz
Published: December 2019

Aim: CO2 emissions and the related climate change are a global problem, where the direct impact of actions of individual countries depends on their total share in CO2 emissions. In order to assess the potential for policy measures, the openness of an economy, and the related import and export and their impacts on emissions should be considered. The aim of this paper is the attempt to show the real CO2 emissions of the Netherlands as well as the impact of its trade on CO2 emissions in other countries in the world and in the EU in 2015.Design / Research methods: This study was conducted on the group of countries that are the major emitters of CO2 in the world including most of the EU members. Countries with negligible CO2 emissions were omitted. Actual CO2 emissions were obtained by applying the actual emission factor. This takes into account the transfer of CO2 in export products and services as well as those imported by particular countries.Conclusions / findings: The real CO2 emissions in the Netherlands are significantly different from the gross values, which represent the CO2 emissions in the particular countries. It is also important to indicate that isolated actions of a single country within the European Union itself do not deliver the intended global and regional target – significant CO2 emissions reduction. The approach proposed in this study, when applied, may have serious implications for individual EU member states in implementing their energy policy objectives.Originality / value of the article: The article shows a different approach to the issue of CO2 emission, including the importance of international trade in a globalizing world.
Teaching and mindsets regarding sustainable development – a Mexican case study
Authors: Zepeda Quintana David Slim , Esquer Javier , Anaya Carlos
Published: December 2019

Aim: The world has become increasingly interconnected and complex. This represents a very serious problem for sustainable development; therefore, the development of instruments that reduces ignorance as well as fragilities are required, this with the intention of being prepared to deal with unexpected events that can threaten sustainability. In this context, universities emerges as a key player since they have the responsibility to lead society towards a sustainable future through the generation of professionals, managers and decision makers which play significant roles in national and global economies; however, it seems that the talent and human resources that are being generated lack the capacity to face these complex problems. This research aims  to identify if teaching interventions, applied to engineering students, produces changes on students perception about business sustainability and sustainable development and, as consequence, identify if the creation of necessary cognitive capabilities for the solution of complex problems that can lead us to collapse scenarios can be produced on students.

Design / Research methods: Questionnaires were applied in a Mexican university. The experiment consists of three phases: (1) a pre-test (n=337), (2) intervention and (3) a post-test (n=329) to see the differences after the interventions. Analysis has been carried out based in hypothesis testing through z-test in order to identify significative changes among the two samples.

Conclusions / findings: Changes in the students' perception were observed. This means that the conditions for teaching sustainable development and sustainable business in this case of study can potentially contribute to creating in students the cognitive capabilities necessary to contribute to business sustainability. The results must be threated carefully; nevertheless, they provide the basis for further research.

Originality / value of the article: This paper makes substantial and original contributions to knowledge in the field through empirical approach; provide a unique and explorative perspective of the situation of current conditions for teaching sustainable development and sustainable business and presents potential contributions in to the creation of students with the awareness and capacities to solve the complex problems of sustainable development
Do mergers and acquisitions increase default risk? Evidence from the European market
Authors: Bessler Wolfgang , Steenbeek Hidde , Westerman Wim
Published: December 2019

Aim: In this study, we examine the changes in default risk of the bidder over the course of a merger or acquisition. The data set consists of 531 deals in which the acquirers are European firms. We employ a general set of determinants to analyse the change in default risk and extend the literature by providing new empirical evidence for the European capital market.

Research design: Abnormal returns are analysed to provide preliminary insights into the merger induced valuation effects. All hypothesized relationships on the changes in default risk are tested via a regression analysis. We differentiate these results further by analysing which factors determine the increase in default risk.

Findings: Previous research on this issue reported mixed results. The main finding of our empirical analysis is that, on average, mergers and acquisitions of European bidders significantly increase default risk during the post-merger period.

Originality: This study adds to the mergers and acquisitions literature for European bidders and targets. The empirical findings suggest that some observed relationships and determinants are different in Europe than in the United States.

Implications: This research introduces a default risk model that could be applied to predict bidder performance subsequent to a merger or acquisition by analysing possible changes in default risk of the bidder. It also provides some possible explanations for the average increase in default risk. This study may help practitioners to better assess the potential risks when acquiring other firms.

Key words: mergers & acquisitions, abnormal returns, default risk, Europe

Authors: Chavarry Vallejos Carlos Magno , Rojo Gutiérrez Marco Antonio
Published: December 2019

Se identifica la correspondencia de procesos que interactúan en la dirección de proyectos para inducir a la reducción de costos y con ello a la optimización de los recursos en la construcción de edificios multifamiliares del Programa Mivivienda en Lima Metropolitana, Perú. La fase de planificación de los proyectos, donde se da la estructura de descomposición de los trabajos (EDT), no guarda relación con los trabajos realizados en la ejecución de las actividades, es decir, provoca una desarticulación entre la planificación y el control de los costos. Esta investigación aporta evidencia de que la correspondencia de procesos para determinar el presupuesto fue del 78%, seguido de los procesos para controlar los costos y para planificar con un 64%, siendo el proceso de estimar los costos con la menor correspondencia con un 53%. De acuerdo con estos resultados, se concluye que la reducción del costo después de aplicar el plan de mejora en la ejecución de una edificación multifamiliar es del 4.76% del costo directo del presupuesto base y terminando 2.32% antes del plazo programado. Se emplea el método deductivo, de orientación aplicada, con enfoque cuantitativo y de fuente de recolección de datos pro lectiva. El tipo del estudio es descriptivo, correlacional y explicativo, basado en un diseño no experimental, transversal y prospectivo. La población estuvo conformada por un total 128 proyectos, en donde se realizó un muestreo aleatorio sistemático, la encuesta es transversal y la técnica la entrevista es personal. El instrumento utilizado fue un cuestionario semiestructurado, constituido por preguntas cerradas, con valores dicotómicos.
