Enraizaimento de estacas de Bougainvillea spectabilis Willd. com o uso de ácido indolbutírico
Authors: Loss Arcangelo , Costa Elias Mendes , Pereira Heitor Paulo Nascimento , Almeida Jander Ferreira 
Published: July 2015

O uso de ácido indolbutírico (IBA) como estimulador do enraizamento em estacas de Bougainvillea spectabilis Willd. pode propiciar aumento de raízes para a formação de mudas comercializáveis. Objetivou-se avaliar o enraizamento, a formação de brotos e a sobrevivência de estacas herbáceas, lenhosas e semi-lenhosas de Bougainvillea com o uso de ácido indolbutírico (IBA). As estacas foram coletadas e tratadas com o IBA (1000 e 2000 mg/lt). Aos 56 dias avaliaram-se a porcentagem de estacas vivas, enraizadas e com brotos; o número de brotos e de raízes por estaca e o comprimento da maior raiz e maior broto. As menores porcentagens de enraizamento foram verificadas nas estacas sem o uso de IBA. Maiores diferenças foram verificadas para as estacas lenhosas. O uso do IBA favorece o enraizamento de estacas de Bougainvillea, com melhor desempenho para as estacas lenhosas e na concentração de 2000 mg/lt de IBA.<div id="__if72ru4sdfsdfrkjahiuyi_once" style="display: none;"> </div><div id="__zsc_once"> </div><div id="__if72ru4sdfsdfruh7fewui_once" style="display: none;"> </div><div id="__hggasdgjhsagd_once" style="display: none;"> </div>
Global Polynomial Kernel Hazard Estimation
Authors: Hiabu Munir , Martínez-Miranda María Dolores , Nielsen Jens Perch , Spreeuw Jaap , Tanggaard Carsten , Villegas Andrés M. 
Published: July 2015

<p>This paper introduces a new bias reducing method for kernel hazard estimation. The method is called global polynomial adjustment (GPA). It is a global correction which is applicable to any kernel hazard estimator. The estimator works well from a theoretical point of view as it asymptotically reduces bias with unchanged variance. A simulation study investigates the finite-sample properties of GPA. The method is tested on local constant and local linear estimators. From the simulation experiment we conclude that the global estimator improves the goodness-of-fit. An especially encouraging result is that the bias-correction works well for small samples, where traditional bias reduction methods have a tendency to fail.</p>
Slashed Exponentiated Rayleigh Distribution
Authors: Salinas Hugo S. , Iriarte Yuri A. , Bolfarine Heleno 
Published: July 2015

<p>In this paper we introduce a new distribution for modeling positive data with high kurtosis. This distribution can be seen as an extension of the exponentiated Rayleigh distribution. This extension builds on the quotient of two independent random variables, one exponentiated Rayleigh in the numerator and Beta(q,1) in the denominator with q&gt;0. It is called the slashed exponentiated Rayleigh random variable. There is evidence that the distribution of this new variable can be more flexible in terms of modeling the kurtosis regarding the exponentiated Rayleigh distribution. The properties of this distribution are studied and the parameter estimates are calculated using the maximum likelihood method. An application with real data reveals good performance of this new distribution.</p>
Calculation of Modal Contributions to Heat Transfer across Si/Ge Interfaces
Authors: Gordiz Kiarash , Henry Asegun 
Published: July 2015

ABSTRACTUsing our newly proposed interface conductance modal analysis (ICMA) formalism, we study the modal contributions to thermal interface conductance (G ) across the interface of crystalline silicon and crystalline germanium. We present the accumulation functions of G at different temperatures and predict G as a function of temperature after proper quantum-corrections have been applied. Different classes of vibration are identified across the interface, among which interfacial modes are determined to have the highest per mode contribution to G . The results demonstrate the ability of ICMA in not only calculating the spectral contributions to G but exactly pinpointing the shape of each vibrational eigen state.
Heat Transfer Performance of Micro-Porous Copper Foams with Homogeneous and Hybrid Structures Manufactured by Lost Carbonate Sintering
Authors: Baloyo Jan Mary , Zhao Yuyuan 
Published: July 2015

ABSTRACTThe heat transfer coefficients of homogeneous and hybrid micro-porous copper foams, produced by the Lost Carbonate Sintering (LCS) process, were measured under one-dimensional forced convection conditions using water coolant. In general, increasing the water flow rate led to an increase in the heat transfer coefficients. For homogeneous samples, the optimum heat transfer performance was observed for samples with 60% porosity. Different trends in the heat transfer coefficients were found in samples with hybrid structures. Firstly, for horizontal bilayer structures, placing the high porosity layer by the heater gave a higher heat transfer coefficient than the other way round. Secondly, for integrated vertical bilayer structures, having the high porosity layer by the water inlet gave a better heat transfer performance. Lastly, for segmented vertical bilayer samples, having the low porosity layer by the water inlet offered the greatest heat transfer coefficient overall, which is five times higher than its homogeneous counterpart.
Prospects of Young Professionals in the Academic Labor Market: Global Comparison and Assessment
Authors: Finkelstein Martin , Iglesias Kevin , Panova Anna , Yudkevich Maria 
Published: July 2015

We offer an analytical model to assess prospects for young faculty based on an analysis of conditions and opportunities of PhD graduates entering the academic market in ten countries: Brazil, China, India, France, Germany, Norway, Russia, Portugal, the Republic of South Africa, and the United States. We have singled out four indicators of demand: a) student enrollment growth rate; b) expenses for research and development and for education; c) the age and rank distribution of current faculty in accordance with national retirement policies; and d) development of technology, emergence of new learning models, and the extent to which these models involve students and faculty. Fundamental factors affecting the supply include: 1) the national system’s reliance on PhD production, and 2) status of post-graduate programs: whether they are the first step in academic career or only a preparatory phase. We have assessed efficiency of faculty recruitment based on openness of search and screening processes and the relative competition for new positions. We have found that the size of national systems in terms of students and staff has expanded considerably, while their proportion in national economies of the countries has remained almost the same. Demand driven by growth is relatively low in Europe, being constrained by ever lower accessibility of entry-level positions and by the job conditions offered there. Most countries — all except China and South Africa — tend to recruit faculty from newly degree graduates. Supply of PhDs (either native or foreign) is quite favorable, mostly due to female academics. The best part of the ten systems that we have analyzed stick to open competition principles when hiring faculty, but at least three systems (Russia, China and India) apply a less open and competitive approach at all levels.
A Comparative Study of Mathematics Teachers’ Beliefs and Practices in Russia, Estonia, and Latvia
Authors: Kardanova Elena , Ponomareva Alena , Osin Evgeniy , Safuanov Ildar 
Published: July 2015

Teachers’ beliefs should be changed in order to introduce modern teaching methods in education. The notion of “belief” combines the ideas, attitudes, and personal philosophies teachers apply in their work. We differentiate between traditional beliefs about teaching as a direct transfer of knowledge and constructivist beliefs assuming that students construct their knowledge themselves through specifically organized activities. We have analyzed the key teacher belief research projects: the OECD’s Teaching and Learning International Survey (TALIS), the cross-cultural Teacher Education and Development Study in Mathematics (TEDS-M), and the Nordic-Baltic Comparative Research in Mathematics Education (NorBA) that we borrowed a questionnaire from. Our survey involved teachers of mathematics in three countries: 390 teachers in Latvia (of which 95 with Russian as their native tongue), 332 teachers in Estonia (of which 92 with Russian as their native tongue), and 1,096 teachers in the Russian Federation. We have found that differences between teachers in different countries were statistically important in all the variables used in the study, regardless of whether Estonian and Latvian teachers were Russian-speaking or not. All teachers implemented their beliefs in their everyday classroom practices. 36% of teachers in Russia had a high level of constructivism (as compared to 26% in Latvia and 18% in Estonia). Proportion of teachers with low levels of traditionalism in Latvia and Estonia (appr. 25% in both) was higher than the same proportion among Russian teachers (17.5%). We have come to a conclusion that different approaches to education system reforms in Russia and in the Baltic states have resulted in a significant diversity of beliefs among teachers of mathematics. Thus, proportion of teachers with low levels of traditionalist beliefs has grown in the Baltic countries more than in Russia, which explains to some extent higher PISA points of Estonian and Latvian students.
Myths and Stereotypes: Some Comments on the History of Education in the Kingdom of Poland in the 19th Century
Authors: Schiller-Walicka Joanna 
Published: July 2015

Some widespread beliefs about school and instruction in Poland need to be reexamined. It would be an unreasonable simplification to believe that the educational system of Poland was exposed to russification throughout the whole 19th century. In reality, the educational policy of the Kingdom of Poland was not unchangeable, and the school system was different in different periods. Russificationis understood as making non-Russian communities adopt the Russian language, culture and Orthodoxy, including administrative initiatives to make non-Russians give up their national identity in favor of the Russian one. The educational system in the country, if judged by the language of teaching and by the ethnic composition of the teaching staff, was absolutely Polish in January 1863, just before the January Uprising. It was only in the 1870s that the russification began. It would even be more appropriate to talk about multiple russifications, their consequences differing in intensity and duration; meanwhile, some of the periods of the 19th century were not affected by the phenomenon at all. We also analyze specific features of the educational policy in Poland: during the Duchy of Warsaw (1807–1815) —development of an efficient multilevel system of public education that honored interests of each social class; in the 1820s — increased control over instruction and the clerical conservative trends in changing the content of education; in the period between the November and January Uprisings — unification of the educational system of Congress Poland with the Russian one; and, finally, the return to the Polish-style instruction on the rise of the so-called Post-Sevastopol Thaw. Special focus is placed on the 46-year existence of the Russian university in Warsaw as an institution that was forced through by Russian authorities but succeeded in developing its own university traditions and goals in culture and science.
The Practice of Implementing International Scholarships: Experience of the Republic of Kazakhstan
Authors: Sagintayeva Aida , Ashirbekov Adil 
Published: July 2015

Bolashak Kazakhstan International Presidential Scholarship was introduced to provide citizens with access to advanced knowledge in newly emerging fields when economy was being restructured and manufacturing industries were being pushed out by innovational ones. The Bolashak Project was launched in 1994 and involved 6,282 people by 2013. The initiative-related experience is analyzed based on the documents regulating participation in the program and on a survey among administrators, scholars and graduates conducted by the Graduate School of Education of Nazarbayev University between 2011 and 2013. Throughout the twenty years of existence, the program has enhanced its effects in the following aspects: providing equal access to participation in the program for all citizens of the country; identifying the priority areas for degree programs; developing the list of foreign higher educational institutions to provide an opportunity for learning abroad; determining the levels of education that need financing under the program; creating conditions to make scholars of the program return to the Republic of Kazakhstan.
The organicity of science
Authors: Gafton Francisc 
Published: July 2015

The systemic character of entities implies their being formed of discrete elements whose conjunction generates hierarchical structures, functions, forces, and roles. While the observation and study of entities entails their segregation with respect to certain sets of criteria, their understanding follows from their thorough comprehension, in plenary connection with the environment of which they are component, product, and factor.
Having the profound role of bringing the human being in the state of knowing and understanding the Universe, science (including the methodology that invents and governs paths, and the apparatus that makes the entire endeavour operational) follows this model of specialized division. Starting from the initial common state, science develops its observations by identifying and describing the reality and its specialized components, in accordance with how they are structured and function, constantly tailoring its means of investigations to the genetic, structural, and functional peculiarities of those aspects.
The completion and evolution of science are consequent to the assimilation of this approach beyond the interdisciplinary level, and arise from the conjunction of scientific knowledge, methods, and instruments, aimed at reflecting reality in its entirety and integrality. This outcome requires a recurrent reconsideration and revision of the organism of science.
Organicitatea științei
Authors: Gafton Francisc 
Published: July 2015

Caracterul sistemic al entităților presupune că acestea sînt formate din elemente discrete, a căror conjuncție generează structuri, funcții, forțe și roluri ierarhizate. Observarea și cercetarea entităților presupune la un moment dat segregarea lor în relație cu anumite seturi de criterii, înțelegerea entităților urmînd cuprinderii acestora în integralitate și în deplina lor conexiune cu mediul a cărui componentă, produs și factor sînt.
Avînd rostul profund de a aduce ființa umană în starea de cunoaștere și înțelegere a Universului, știința (inclusiv metodologia care inventează și reglementează căi și instrumentarul care face operațional întregul demers) urmează acest model al diviziunii specializate. Plecînd de la starea inițială de nediferențiere, știința își dezvoltă observațiile pînă la identificarea și descrierea realității și a componentelor ei specializate, în conformitate cu modalitățile de orînduire și de funcționare a lor, acomodîndu-și mijloacele de investigare la particularitățile genetice, structurale și funcționale ale respectivelor aspecte.
Împlinirea și evoluția științei sînt consecvente înglobării acestui nivel, depășirii celui interdisciplinar, și decurg din conjugarea cunoștințelor, metodelor și instrumentelor ei, spre a reflecta realitatea în deplinătatea și integritatea acesteia. Acest rezultat necesită periodica regîndire și reactualizare a organismului științei.
The interdependencies of bilingual behaviour. Psycholinguistic and sociolinguistic profile of Hungarian-Romanian bilinguals
Authors: Tódor Erika-Mária 
Published: July 2015

This paper presents the specific features of a school population in Romania for whom Romanian is a non-native language, their mother tongue being Hungarian. The first part of the study offers a description of the main characteristics of the verbal behaviour of this bilingual population. The first subheading will discuss, on the one hand, the linguistic profile of the subjects (linguistic interference, linguistic pseudo-creativity etc.) and, on the other hand, it will present the main aspects of the socio-affective dimension of verbal behaviour (such as communicational anguish, displacement of communicational intention, linguistic code switching etc.). Practically, these features can be followed in the case of other bi(multi)lingual speakers as well. The second part of the paper presents certain lexical and semantic interference and vocabulary activating habits in the case of bilingual persons, relating them to the linguistic context and the linguistic landscape.
The formulated data and observations represent a synthesis of empirical research carried out between 2000–2013 through different methods, such as: observation, case studies (within the context of the data referring to the profile of language behaviour), structured interviews and questionnaires (employed in the study of the linguistic landscape). The main aim of this study is to offer a socio- and psycholinguistic profile of Hungarian-Romanian bilingualism set in a holistic context.

Os CONCEITOS DE “SEMELHANÇA”, “DIFERENÇA” E “IDENTIDADE” EM FOUCAULT E SUAS RELAÇÕES COM A CRÍTICA IMPRESSIONISTA BRASILEIRA
Authors: Reis Nelson Ricardo Guedes dos 
Published: July 2015

Para Foucault, o processo epistemológico da civilização ocidental passa por três momentos: até o século 16, esteve ligado ao conceito de semelhança; a partir desse século, até o século 19, ao conceito de diferença. No século 20, a relação dos elementos internos do sistema passou a ser o determinante. A crítica impressionista brasileira se adéqua ao processo epistemológico da primeira fase.

IMAGENS DA DESCONSTRUÇÃO NA HISTÓRIA DO BRASIL, DE MURILO MENDES
Authors: Frota Luciane Da Mota 
Published: July 2015

Este estudo se propõe a fazer uma análise da postura desconstrucionista adotada pelo poeta Murilo Mendes nos poemas que compõem sua obra História do Brasil. Produzidos logo depois da fase inicial do Modernismo, tida como a mais radical e mais ousada, os poemas desse livro servem perfeitamente de base a uma leitura daquilo que Jacques Derrida propôs como desmanche de princípios e de postulados. Enfim, numa leitura dos textos murilianos poder-se-á descobrir significados que não se revelam claramente ao leitor, pois desconstroem um legado histórico construído ao longo de anos, para se propor uma nova identidade e história tipicamente nacionais
Derrida e a essência do político em Espectros de Marx

A Literatura Comparada como dobra crítica e a estrutura paranoica da racionalidade enciclopédica
Authors: Lee Henrique de Oliveira 
Published: July 2015

No seminário “Le concept de littérature comparée et les problèmes théorique de la traduction”, lecionado em Yale em 1979-80, Jacques Derrida explora aspectos institucionais e disciplinares da “Literatura Comparada”. Este trabalho tem por objetivo remontar e discutir argumentos da primeira sessão do seminário de 1979 e apontar a sua ligação com formulações posteriores, tal como a noção de Literatura como uma “instituição sem instituído”.
