El inicio y desarrollo de la geología en la Universidad de Buenos Aires
Authors: Ramos Víctor 
Published: May 2019

Las clases de Pellegrino Strobel en la Universidad de Buenos Aires marcan el comienzo de la enseñanza de la geología en Argentina. En los años transcurridos se pueden reconocer seis etapas. La primera etapa pionera iniciada por Strobel en 1865, culmina con Eduardo Aguirre y transcurre desde 1878 a 1906. La segunda consolida la enseñanza con Enrique Hermitte, quien forma los primeros profesionales que sirvieron al país en diferentes disciplinas y dirige las tesis de los primeros egresados. La tercera marca el inicio de la investigación geológica liderada por Juan Keidel y Pablo Groeber. Produce un cambio en la enseñanza y en las investigaciones, con la tesis doctoral en 1933 de Horacio J. Harrington de excelente nivel científico. Harrington como director del Instituto de Geología de la universidad y como profesor fue uno de los mejores geólogos argentinos de la primera mitad del siglo XX. El golpe militar en 1955 marca el inicio de la cuarta etapa liderada por Félix González Bonorino y caracterizada por una educación más sólida en diferentes especialidades y un moderno plan de estudios. Tuvo docentes de calidad, con profesores formados en el exterior y extranjeros, que enseñaron disciplinas poco desarrolladas en el país. El período 1966-1983 fue marcado por su opacidad, con algunas excepciones como el desarrollo del paleomagnetismo por Daniel Valencio y sus discípulos. La última etapa comienza con la vuelta a la democracia, que junto a concursos docentes abiertos sin restricciones, permite alcanzar el presente grado de desarrollo.
Las investigaciones geológicas del Museo de La Plata desde la época del centenario a la del sesquicentenario: 1906-1966

Published: May 2019

Entre 1884 y 1905, bajo la dirección de Francisco P. Moreno el Museo de la Plata tuvo una clara proyección nacional y fue protagonista del desarrollo del conocimiento geográfico y geológico de diferentes partes del país, especialmente de la Patagonia. En 1905 pasó a integrar la Universidad Nacional de La Plata, situación que determinó la renuncia de F. P. Moreno, La dirección fue asumida por el antropólogo S. Lafone Quevedo y el museo fue organizado en varias escuelas, lo cual significaría, en años posteriores, una casi excluyente acción tendiente a su progresiva integración a la docencia. En 1920 fue designado director el arqueólogo L. M. Torres, quien debió retirarse en 1932 debido a problemas de salud. Entre 1906 y 1934, las investigaciones geológicas fueron limitadas y se circunscribieron fundamentalmente al accionar individual de S. Roth y W. Schiller, con algunos aportes de M. Kantor y E. Herrero Ducloux. Roth mayormente completó y publicó resultados de estudios realizados en la época de Moreno, mientras que Schiller hizo contribuciones sobre la geología de la alta cordillera de Mendoza y San Juan, de las Sierras Australes de Buenos Aires y de la región petrolífera de Comodoro Rivadavia, en general respondiendo a iniciativas ajenas al museo. En 1934 se incorporó J. Frenguelli, quien sería Director de la institución entre 1935 y 1946. Durante las décadas de 1930 y 1940 las investigaciones geológicas originadas en el museo adquirieron importancia y se debieron fundamentalmente a Frenguelli y en menor medida a E. Fossa Mancini, a las que se sumaron los aportes paleontológicos que realizó A. Cabrera, a partir de 1925. Las contribuciones de Frenguelli se focalizaron en el Cenozoico superior y en la estratigrafía y las plantas fósiles de los estratos continentales del Paleozoico superior y Mesozoico inferior. Otro de los aportes institucionales importantes fue la formación de numerosos geólogos, los que a partir de la década de 1940 realizaron estudios desde diferentes instituciones y empresas en todo el país. En 1946 se produjo un quiebre a nivel nacional e institucional que significó el desplazamiento de J. Frenguelli, la transformación del Instituto del Museo en Facultad de Ciencias Naturales y Museo, con prioridad en la enseñanza, todo lo cual significó en la década de 1950 la pérdida de la continuidad en la investigación y en las publicaciones. La creación de la CIC y el CONICET y la introducción del sistema de dedicación exclusiva a fines de los 50 sentaron condiciones que en la década de 1960 llevarían a un intento de reiniciar investigaciones planificadas en geología y paleontología.

Published: May 2019

Abstract
In the spring of 2017, Stołowe Mountains National Park started a research program related to the protection of water resources. The research program was started because of, among others, the growing problems of water resources and the dying of spruce trees. One of the projects commissioned by the Park was ‘Monitoring the impact of renaturisation and hydrological status on changes in the biomass of trees and stands’. The monitoring covered spruce stands growing along the main watercourse of the Park (the Czerwona Woda). As a part of the study, three rectangular surfaces (from 0.45 to 0.50 ha) and 10 circular areas (0.04 ha each) were established. On fenced rectangular surfaces, 10 model trees were selected using the Draudt method. They were monitored using hemispheric cameras (changes in crowns), dendrometers (changes in the circumference of stems) and minirhizotronami (changes in the root layer). In addition to the measurements of all the trees on the surface, imaging with terrestrial laser scanning and hemispherical images was done.
The data and results presented in this work were created as a result of the implementation of a project financed from funds related to the forestry fund of the State Forests National Forest Holding.
The Determination of Performance Measures by Using a Balanced Scorecard Framework
Authors: Kefe Irem 
Published: May 2019

Abstract
The aim of this study was to determine the contributions of the balanced scorecard (BSC) methods to identify the relationship between the objectives and activities and examine how the BSC should be formed in a manufacturing company. The BSC framework was examined via a case study in a yarn manufacturing company. The activities to be carried out by the company to achieve its objectives and how the appropriate measures are determined in evaluating the contribution of the activities to the achievement of objectives are explained under the BSC approach. The BSC implementation and adaptation have facilitated in a family owned company because of its fast decision-making process. Objectives are made clear in accordance with the company’s strategy and causal relationship between objectives and activities are linked by the strategy map. The BSC implementation shows that financial measures are not enough to evaluate the effects of all the activities on the objectives in a company. The cooperation between departments in the company and the efficiency of corporation meetings increases. The meetings have become more result-oriented due to clarifying objectives and responsibility of individual levels.

Published: May 2019

Abstract
Forest Reserves in Southwestern Nigeria have been threatened by urbanization and anthropogenic activities and the rate of deforestation is not known. This study examined the vegetation characteristics of Akure Forest Reserve using optical remote sensing data. It also assessed the changing pattern in the forest reserve between 1986 and 2017. Global Navigation Satellite System (GNSS) receiver was used to capture the location of the prominent settlements that surrounded the Forest Reserve in order to evaluate their effects on the forest. Landsat TM 1986, Landsat ETM+ 2002 and Landsat OLI_TIRS 2017 with 30m resolution were classified to assess the spatio-temporal changing pattern of the forest reserve. The results showed different composition of vegetation, which include undisturbed forest, secondary regrowth and farmlands. The study further revealed that in 1986, 2002 and 2017, undisturbed forest constituted 63.3%, 32.4% and 32.1% of the entire land area respectively, while secondary regrowth occupied 8.3% in 1986, 9.5% in 2002 and 15.6% in 2017. The farmlands had erratic growth between 1986 and 2017. It was 16.9% in 1986, 22.1% in 2002 and 17.5% in 2017. The bare ground exhibited inconsistency in the coverage. In 1986 the areal extent was 11.5%, when it increased to 36% in 2002 and decreased to 31.9% in 2017. In conclusion, the study revealed the extent of forest depletion at Akure Forest Reserve and it is therefore important that the residents, the government and the researchers show major concern about some of the critical factors to human beings that are responsible for forest depletion.
Genetic analysis of cabbages and related cultivated plants using the bag-of-words model
Authors: Owsianková Hana , Faltýnek Dan , Kučera Ondřej 
Published: May 2019

Abstract
In this study, we aim to introduce the analytical method bag-of-words, which is mainly used as a tool for the analysis (document classification, authorship attribution and so on; e.g. [1, 2]) of natural languages. Quantitative linguistic methods similar to bag-of-words (e.g. Damerau–Levenshtein distance in the paper by Serva and Petroni [3]) have been used for the mapping of language evolution within the field of glottochronology. We attempt to apply this method in the field of biological taxonomy – on the Brassicaceae (Cruciferae) family. The subjects of our interest are well-known cultivated crops, which at first sight are morphologically very different and culturally perceived as objects of different interests (e.g. oil from oilseed rape, turnip as animal feed and cabbage as a side dish). Despite the phenotypic divergence of these crops, they are very closely related, which is not morphologically obvious at first sight. For this reason, we think that Brassicaceae crops are appropriate illustrative examples for introducing the method. For the analysis, we use genetic markers (internal transcribed spacer [ITS] and maturase K [matK]). Until now, the bag-of-words model has not been used for biological taxonomisation purposes; therefore, the results of the bagof-words analysis are compared with the existing very well-developed Brassica taxonomy. Our goal is to present a method that is suitable for language development reconstruction as well as possibly being usable for biological taxonomy purposes.

Abstract

Introduction: Hypertension (HT) is characterized by high blood pressure. The reninangiotensin-aldosterone system (RAAS) plays a crucial role in blood pressure (BP) regulation by maintaining vascular tone and the water-sodium balance. We aimed to investigate whether there is any relation between AGT (M235T), ACE (I/D), and AGTR1 (A1166C) genetic polymorphisms and hypertension among Turkish people from Southeast Anatolia.

Method and Results: A total of 210 individuals, consisting of 102 healthy controls and 108 patients with essential hypertension admitted to the Cardiology Department of the Adıyaman University Research and Application Hospital were included the study. DNA isolation was performed from the blood samples via commercial kit. Genotype determination was determined using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Statistically significant differences were found between the control and patient groups in terms of genotype distribution and allelic frequencies of ACE I/D polymorphisms. Significant differences were found in the frequencies of ICM, DCM, DCT, DAT between the patient and control groups.

Conclusions: In this study, we found a significant association of ACE I/D polymorphism with HT, and we showed that the I allele can increase the risk of HT in Turkish people from Southeast Anatolia. Although we did not find any association between independent AGT M235T and AGT1R A1166C polymorphisms and HT, we observed that the DCM, DCT, and DAT haplotypes of ACE/AGT1R/AGT polymorphisms reduced the risk of hypertension, while the ICM haplotype increased it.

Conversations between future French teachers: a proposal of design for on-line oral interaction practice in initial training
Abstract
In this paper, we present the proposal for the design of an online course that aims at improving oral interaction skills in the context of pre-service foreign languages teacher training . The support given to students during the French Language Degree Supervised Internship at UnB enabled us to identify shortcomings of this skill. As a result, we considered a curricular alternative to allow more space and time for the target language practice in real context settings. We adopted the Design-Based Research methodology, because of the answers that it brings to our aim of designing a course involving digital technology, oral interaction and mediation, as well as the essential link promoted between design, research and practice. According to this approach, we hereby present the analysis, design, development and implementation stages of the extension course “Conversations between pre-service French teachers”, offered since 2013 in partnership with the University of Poitiers, France.

A influência da idade na inteligibilidade e no grau de sotaque estrangeiro de alunos brasileiros de inglês de nível avançado
Authors: Lima Jr Ronaldo Mangueira 
Published: May 2019

Resumo
Este estudo investigou a influência que a idade com a qual brasileiros começam a estudar inglês no Brasil pode ter na sua pronúncia ao final do curso avançado de inglês, mais especificamente na inteligibilidade e no grau de sotaque estrangeiro. Alunos que estavam cursando o último semestre de seus cursos e haviam começado o curso em diferentes idades foram gravados lendo um parágrafo e falando espontaneamente. Um grupo controle de falantes nativos de inglês também foi gravado desempenhando as mesmas tarefas. Os níveis de inteligibilidade e de grau de sotaque estrangeiro dos participantes foram avaliados por um painel de nove juízes, e os resultados mostram uma tendência de declínio na pronúncia com o aumento da idade de início do curso, com um grande declínio mesmo entre o grupo controle e os aprendizes mais novos. Alguns aprendizes excepcionais, com níveis de inteligibilidade e de grau de sotaque estrangeiro próximos aos dos falantes nativos, foram encontrados. Os resultados estão alinhados ao conceito de aquisição de segunda língua como sistema dinâmico, sob a qual os dados foram analisados.

The influence of age on intelligibility and rate of foreign accent of Brazilian advanced learners of English
Abstract
This study has investigated the influence that the age in which Brazilian learners begin to study English in Brazil may have on their pronunciation at the end of their advanced English courses, especially on their intelligibility and rate of foreign accent. Learners who were in the last semester of their courses and who had begun studying at different ages were recorded reading a paragraph and speaking spontaneously. A control group of native speakers of English was also recorded performing the same tasks. Participants’ levels of intelligibility and of rate of foreign accent were assessed by a panel of nine judges and the results show a tendency of decline in their pronunciation as the age in which they began studying increases; with a sharp decline even between the control group and the earliest starters. A few exceptional learners, with intelligibility and rate of foreign accent levels close to those of the native speakers, were found. The results are aligned with the concept of second language acquisition as a dynamic system, under which the data were analyzed.

In this work, we make some reflections on the practices of digital literacy experienced by a group of Distance Education users of Virtual Learning Environment - VLE SOLAR, Federal University of Ceará - UFC. We base our work mainly on r83eflections (CASSANY, 2005; Eshet-Alkalai, 2004; SOARES, 2002; XAVIER, 2002; Buzato, 2001; Lévy, 1999). We situate this research as an explanatory research diagnostic character (GIL, 2002) located in the qualitative-interpretative paradigm (BORTONI-RICARDO, 2008). We construct our sample by two sources: two questionnaires and the analysis of the activities of SOLAR. The results show that the practices of recurrent digital literacy in the data are diverse and are primarily related to vernacular literacy practices. These practices are linked to different agencies of literacy with which these participants were and are related. Our data indicate that being literate digital implies taking changes in the modes of approaching the text with the use and interaction of multiple semiosis in texts that are in a digital format, in general the screen.
