Descomplicando o Celpe-Bras: Explicitação e Aplicação do Construto Bakhtiniano no Design de Um Curso Online para o Instituto Guimarães Rosa

Alexandre Ferreira Martins,Thamis Larissa Silveira 부산외국어대학교 중남미지역원 2023 이베로아메리카 Vol.25 No.2

This text addresses the educational design(Bulla 2014) of Descomplicando o Celpe-Bras, an online course developed for the Guimaraes Rosa Institute. Over a period of more than twenty years, the Celpe-Bras has played a significant role as an instrument of language policy in the field of Portuguese as an additional language(PLA), influencing both educational processes and the agents involved in them(Ye 2009). The design of this course is based on the notion of speech genres(Bakhtin 1984), a theoretical assumption of the examination itself. First, we present the Celpe-Bras and its theoretical foundations. Subsequently, we demonstrate the course design, explaining the application of theoretical assumptions through the analysis of two of the fifteen lessons. The course proves to be an important tool for those who need to become familiar with its Bakhtinian theoretical construct through the examination.

“Beyond 2010 : A Sketch of Future Economic Challenges for Mongolia”

Alexandre Repkine 동중앙아시아경상학회 2011 한몽경상학회 학술대회 Vol.2011 No.1

In this essay I am outlining the major features of Mongolian economic performance during the last decade and sketch out the most promising avenues of development in the future. It appears that sticking to a smart policy of managing windfall profits resulting from the copper export boom in the future is going to be the main challenge for the Mongolian government to face in the next decennium. Channeling those profits into the public infrastructure and productive investment would make a stark difference between long-term growth and stagnation characteristic of the less fortunate victims of the Dutch disease such as Turkmenistan. The development of ger neighborhoods in the vicinity of Ulaan Baataar is another challenge the Mongolian economy will have to face. Specifically, the problems of ensuring smooth transition of the ger areas into the apartment complexes is going to take a long time, while during this transition major infrastructural problems will have to be addressed. In the last section of this essay I am arguing that the introduction of microfinance system similar to the one implemented by the Grameen bank in Bangladesh would help solve a lot of these transitional problems.

Private tutoring through the internet: globalization and offshoring

Alexandre Ventura,장선화 서울대학교 교육연구소 2010 Asia Pacific Education Review Vol.11 No.1

The private tutoring industry has come forward as the third great sector of education. The common sense representation about private tutoring is changing. The growing search for supplementary educational support services and the technological innovation have created a new paradigm. This paper focuses on one of the most interesting faces of this new phenomenon: the rise of private tutoring through the internet. The very promising market is considered by some analysts as a true explosion on the offer and demand levels. Many families are feeling increasingly unable to provide their children the `` extra help'' they need to meet the requirements of further steps in the education system. So, for several reasons, they are outsourcing and even offshoring this so important and competitive task. The field is full of learning and market opportunities. This is the new globalized world of the less shadow and progressively growing private tutoring in the XXI century.

How Similar are the East Asian Economies? A Cluster Analysis Perspective on Economic Cooperation in the Region

Alexandre Repkine 동중앙아시아경상학회 2012 한몽경상학회 학술대회 Vol.2012 No.1

Recent economic calamities such as the 1997 Asian financial crisis have amply demonstrated the need for increased economic integration in the East Asian economic region. While various forms of economic cooperation are possible, it is important to identify groups, or clusters, of countries that are similar to each other economically. Such similarity not only has been shown to be associated with the increased bilateral trade flows, but also with the increased net welfare gains to the participating countries. I employ a variety of clustering techniques and come up with a clustering solution containing four groups of economically similar countries. The clusters are robust across the estimation procedures. Hierarchical clustering also conducted in this study suggests a sequential agglomerating path for the countries to follow. The results of this study are intended as one of the (many) decision tools used by the parties considering multilateral economic cooperation and trade agreements in the region.

Capability of Tungsten Carbide Micro-mills to Machine Hardened Tool Steel

Alexandre Gilbin,Michaël Fontaine,Gérard Michel,Sébastien Thibaud,Philippe Picard 한국정밀공학회 2013 International Journal of Precision Engineering and Vol. No.

The aim of this study is to optimize micro-mills and their conditions of use to manufacture plastic injection molds in hardened tool steels by micro-milling. The presented results deal with the test of four types of tungsten carbide square end micro-mills in elementary operations with different feed rates and cutting speeds in order to analyze the evolution of cutting forces, cutting stability, tool life,tool wear, surface roughness and burs formation. This experimental approach allows highlighting the influence of cutting conditions,especially feed rate, on burr formation and tool life. This analysis shows a correlation between the micro-mills characteristics (geometry, composition of tungsten carbide) and their wear behavior. Moreover, some dynamic aspects of the micro-milling process are underlined through the influence of cutting speed on cutting stability. This type of experimental study is suitable for the optimization of the tool edge geometry and it reveals the need to develop a predictive model adapted to micro-milling to optimize the dynamic behavior of the tool.

Reinventing the Mongolia-Russia Relationship: a Geoeconomic Perspective

Alexandre Repkine 동중앙아시아경상학회 2009 한몽경상연구 Vol.20 No.1

In this paper I am analyzing Mongolia’s unique geoeconomic location in between Russia and China. I argue that it is essential that Mongolia be considered as a civilization of its own rather than a satellite or vassal of either of its two big neighbors. I start by analyzing Mongolia’s comparative advantages with respect to China and Russia and stress Mongolia’s importance as home to the world’s most significant strategic deposits, and as a transit country. An historical journey reveals that Mongolia has been strongly influenced by the former Soviet Union for most of the twentieth century so that ignoring this influence is counterproductive, while it makes every economic and political sense making use of it. The key idea in this essay is that neither Russia nor China should be trying to make Mongolia part of its sphere of interests. Rather, a balanced cooperation with the two countries is necessary to achieve both economic prosperity and the solution of brewing ethnical problems in the region.

Trends in genotype frequency resulting from breeding for resistance to classical scrapie in Belgium (2006∼2011)

Alexandre Dobly,Sara Van der Heyden,Stefan Roels 대한수의학회 2013 JOURNAL OF VETERINARY SCIENCE Vol.14 No.1

In sheep, susceptibility to scrapie is mainly determined by codons 136, 154, and 171 of the PRNP gene. Five haplotypes are usually present (ARR, ARQ, ARH, AHQ, and VRQ). The ARR haplotype confers the greatest resistance to classical scrapie while VRQ renders animals most susceptible. In 2004,the European Union implemented a breeding program that promotes selection of the ARR haplotype while reducing the incidence of VRQ. From 2006 to 2011 in Belgium, frequency for the ARR/ARR genotypes increased from 38.3% to 63.8%(n = 6,437), the ARQ haplotype diminished from 21.1% to 12.9%, and the VRQ haplotype decreased from 2.0% to 1.7%. The status of codon 141, a determinant for atypical scrapie,was also evaluated. Out of 27 different breeds (n = 5,163), nine were abundant. The ARR/ARR frequency increased in eight of these nine major breeds. The selection program has had a major impact on the ARR haplotype frequency in Belgium. However, the occurrence of atypical scrapie represents a critical point for this program that warrants the continuous monitoring of scrapie. Additionally, genotype frequencies among the breeds varied greatly. Texel, a breed that is common in Belgium, can still be selected for due to its average ARR frequency.

Time-dependent analysis of slender, tapered reinforced concrete columns

Alexandre de Macêdo Wahrhaftig 국제구조공학회 2020 Steel and Composite Structures, An International J Vol.36 No.2

This study analyzed stresses in concrete and its reinforcement, computing the additional loading transferred by concrete creep. The loading varied from zero, structure exclusively under its self-weight, up to the critical buckling load. The studied structure was a real, tapered, reinforced concrete pole. As concrete is a composite material, homogenizing techniques were used in the calculations. Due to the static indetermination for determining the normal forces acting on concrete and reinforcement, equations that considered the balance of forces and compatibility of displacement on cross-sections were employed. In the mathematical solution used to define the critical buckling load, all the elements of the structural dynamics present in the system were considered, including the column self-weight. The structural imperfections were linearized using the geometric stiffness, the proprieties of the concrete were considered according to the guidelines of the American Concrete Institute (ACI 209R), and the ground was modeled as a set of distributed springs along the foundation length. Critical buckling loads were computed at different time intervals after the structure was loaded. Finite element method results were also obtained for comparison. For an interval of 5000 days, the modulus of elasticity and critical buckling load reduced by 36% and 27%, respectively, compared to an interval of zero days. During this time interval, stress on the reinforcement steel reached within 5% of the steel yield strength. The computed strains in that interval stayed below the normative limit.

Rich in Resources: a Blessing or a Curse? The Case of Mongolia

Alexandre Repkine 동중앙아시아경상학회 2011 한몽경상학회 학술대회 Vol.2011 No.1

In this study we are addressing an important question of whether Mongolia's natural abundance in natural resources is likely to promote economic growth in the country or lead it to stagnation. We argue that the natural resource curse is not cast in stone, but that at the same time little can be expected in terms of the economic prosperity if drastic institutional reforms are not undertaken in the near future. Those reforms would have to concern the transparency of Mongolia's financial sector so as to decrease the cost of capital, and government intervention in order to channel the windfall profits from the mining sector into the infrastructural improvements. Such improvements are especially needed in order to reduce Mongolia's comparative disadvantage in terms of its transportation costs. Encouraging innovative processes in the manufacturing sector especially for the export-oriented firms would be another policy priority.

Does Linguistic Diversity Affect International Trade in East and South Asia?

Alexandre Repkine 동중앙아시아경상학회 2013 한몽경상학회 학술대회 Vol.2013 No.1

While linguistic differences impede international trade by creating communication barriers, linguistic heterogeneity is likely to facilitate trade for at least two reasons. First, the scope of comparative advantages will be wider in case the trading partners represent a linguistically heterogeneous environment as a whole. Second, linguistically heterogeneous countries will be more successful dealing with the communication barriers arising as a result of linguistic differences. Using a sample of East and South Asian economies we find empirical evidence in support of the two heterogeneity hypotheses, at the same time confirming the negative effect of linguistic differences found in earlier studies.
