BACKGROUND

Cardiac troponin T concentrations measured with high-sensitivity assays (hs-cTnT) provide important prognostic information for patients with stable coronary artery disease (CAD). However, whether hs-cTnT concentrations mainly reflect left ventricular (LV) remodeling or recurrent myocardial ischemia in this population is not known.

METHODS

We measured hs-cTnT concentrations in 619 subjects with suspected stable CAD in a prospectively designed multicenter study. We identified associations with indices of LV remodeling, as assessed by cardiac MRI and echocardiography, and evidence of myocardial ischemia diagnosed by single positron emission computed tomography.

RESULTS

Median hs-cTnT concentration was 7.8 ng/L (interquartile range, 4.8–11.6 ng/L), and 111 patients (18%) had hs-cTnT concentrations above the upper reference limit (>14 ng/L). Patients with hs-cTnT >14 ng/L had increased LV mass (144 ± 40 g vs 116 ± 34 g; P < 0.001) and volume (179 ± 80 mL vs 158 ± 44 mL; P = 0.006), lower LV ejection fraction (LVEF) (59 ± 14 vs 62 ± 11; P = 0.006) and global longitudinal strain (14.1 ± 3.4% vs 16.9 ± 3.2%; P < 0.001), and more reversible perfusion defects (P = 0.001) and reversible wall motion abnormalities (P = 0.008). Age (P = 0.009), estimated glomerular filtration rate (P = 0.01), LV mass (P = 0.003), LVEF (P = 0.03), and evidence of reversible myocardial ischemia (P = 0.004 for perfusion defects and P = 0.02 for LV wall motion) were all associated with increasing hs-cTnT concentrations in multivariate analysis. We found analogous results when using the revised US upper reference limit of 19 ng/L.

CONCLUSIONS

hs-cTnT concentrations reflect both LV mass and reversible myocardial ischemia in patients with suspected stable CAD.
La expansión territorial de la minería mexicana durante el periodo 2000-2017. Una lectura desde el caso del estado de Morelos
Authors: Téllez Ramírez Isidro , Sánchez Salazar María Teresa
Published: June 2018

Este artículo tiene como objetivo analizar el comportamiento de la expansión territorial de la minería durante los últimos 17 años en el estado de Morelos. Para el examen de esta dimensión de la actividad minera, se consideraron dos indicadores: número de títulos y superficie concesionada. Los resultados muestran que las concesiones para extraer minerales metálicos en esta entidad se multiplicaron sustancialmente durante el periodo de bonanza comprendido entre 2004 y 2013. Se discute así que la ampliación de la minería constituye una modalidad de acumulación de capital basada en el despojo de extensas áreas del subsuelo nacional, en donde influyeron directamente los cambios realizados por el Estado en los marcos legales relativos a la propiedad, aprovechamiento y comercio de los recursos mineros, así como la presencia cada vez mayor de compañías mineras junior de origen canadiense. Se indica, además, que la expansión territorial de la minería en Morelos ha operado sobre las últimas riquezas colectivas que aún no habían sido explotadas: ríos, acuíferos, cerros, manantiales, Áreas Naturales Protegidas y espacios de valor arqueológico. Se concluye que el rechazo social es la única barrera que ha logrado suspender el avance de la expansión minera en esta entidad, lo cual manifiesta la necesidad de modificar la forma en que el Estado mexicano expide los títulos de concesión minera en México.

Authors: Bessa Mariana de Camargo
Published: June 2018

Este artigo tem como objetivo analisar ocorrências de mal-entendidos observadas em uma sala de aula de Português como Língua Estrangeira em ambiente de imersão. Com base nos conceitos de interculturalidade (BYRAM; GRIBKOVA STARKEY, 2002; CANDAU, 2008), face (GOFFMAN, 1980) e mal-entendido (LODER, 2008; SCHEGLOFF; JEFFERSON; SACKS, 1977), este estudo de cunho qualitativo apresenta transcrições de registros de áudio, analisadas a partir dos princípios da Análise da Conversa Etnometodológica. A partir dos resultados obtidos na análise, conclui-se que essas ocorrências de mal-entendidos e estranhamentos estão relacionadas às interpretações divergentes de uma expressão e de uma situação, e às diferenças culturais entre os estudantes. Assim, é papel do professor transformar tais estranhamentos em momentos de aprendizagem, mediando o diálogo e facilitando a troca organizada de expressões conflitantes.

Material para o ensino de português para falantes de Espanhol para o contexto universitário
Authors: Luiza Ferreira Laura Márcia
Published: June 2018

O aumento da oferta de cursos de português para falantes de Língua Espanhola, por meio da ampliação da Rede Brasileira de Ensino no Exterior pelo estado brasileiro, a criação da Universidade Federal da Integração Latino-Americana (UNILA) assim como a crescente procura pela certificação de proficiência atestada pelo exame Celpe-Bras por examinandos de origem dos países da América Latina, contextualizam a demanda de materiais de ensino de português voltados especificamente para o público latino-americano. No presente trabalho, apresento a fundamentação teórico-metodológica que subjaz a elaboração de cinco unidades didáticas propostas para o público de universitários falantes de espanhol como língua materna. Inicialmente, faço uma análise de estudos e propostas que trataram da especificidade do ensino de português para falantes de línguas próximas. Em seguida, discuto os princípios metodológicos, bem como as características do ensino de línguas baseado em tarefas para, ao final, descrever, exemplificar e justificar as decisões tomadas durante a elaboração das unidades didáticas. Embora o trabalho limita-se a uma discussão teórico-metodológica sobre a elaboração de um material didático específico, espera-se que o presente artigo contribua para o debate acerca do ensino de português para falantes de espanhol.
Acolhimento intercultural e ensino de português como língua adicional nas escolas municipais de Foz do Iguaçu
Authors: Ribeiro Simone Beatriz Cordeiro
Published: June 2018

Como o Brasil faz fronteira com vários países de Língua Espanhola, a presença de estrangeiros hispano falantes em instituições de ensino brasileiras é muito frequente. Muitos desses alunos passam a frequentar as escolas brasileiras sem conhecimento algum da Língua Portuguesa e passam a aprendê-la, nestas instâncias, como Português Língua Materna, uma prática de ensino que contribui para a exclusão e o apagamento da sua língua de berço. Diante disso e considerando uma metodologia de educação em línguas, foi proposto o Projeto de Extensão “Ensino de Português como Língua Adicional no Ensino Fundamental I”, objetivando acolher esses discentes e dirimir as sucessivas reprovações e/ou alocações dos mesmos em séries mais iniciais, pelo simples fato de não saberem a Língua Portuguesa. Para tanto, objetiva-se discutir sobre a situação de Tríplice Fronteira vivenciada pela cidade de Foz do Iguaçu, Paraná – Brasil e a prática de acolhimento de estrangeiros nas escolas da rede municipal, no Ensino Fundamental I, sob a ótica de que as Línguas Portuguesa e Espanhola, neste espaço transfronteiriço, se caracterizam como Línguas de Fronteira (STURZA, 2006; RIBEIRO, 2015, 2017a), sugerindo um ensino de Língua Adicional (RODRIGUES, 2013) que suscite o acréscimo, agregando e adicionando conhecimentos, provendo e mantendo o multiculturalismo e o plurilinguismo existente nesta região de fronteira.

Authors: Silva Doralúcia Gil da , Dell'Aglio Débora Dalbosco
Published: June 2018

O estudo do bem-estar subjetivo com adolescentes justifica-se pela importância da identificação e promoção de aspectos positivos nesse período do desenvolvimento. O sexo e a faixa etária têm sido associados à variação da satisfação de vida e afetos positivos e negativos. Assim, este trabalho teve por objetivo avaliar o nível de BES de adolescentes, a partir de um índice que engloba a avaliação de afetos positivos e negativos e a satisfação dos adolescentes com relação aos domínios específicos de suas vidas, observando a associação com sexo e faixa etária. Foram aplicadas a Escala Multidimensional de Satisfação de Vida e a Escala de Afetos Positivos e Negativos para Adolescentes em 426 estudantes (média de idade 14.91 anos; DP=1.65) de escolas públicas de Porto Alegre. Foram observadas médias mais altas entre os meninos nas dimensões satisfação com a família, autoeficácia e bem-estar. As meninas apresentaram maior satisfação com as amizades, maiores níveis de afetos negativos e menor satisfação com a vida. Tais dados indicam a necessidade de intervenções que promovam aspectos positivos entre as adolescentes.

Published: June 2018

Os adolescentes que foram adotados são frequentemente identificados como um grupo em risco em termos de competência social. Neste estudo pretendeu-se analisar a competência social de um grupo de adolescentes adotados, através da comparação com um grupo de adolescentes em acolhimento residencial (AR) e de um grupo de adolescentes que viviam com a família de nascimento e explorar a sua relação com variáveis relativas à adoção. Participaram neste estudo 135 adolescentes, com idades compreendidas entre os 12 e os 17 anos, dos quais 45 foram adotados, 45 estavam em AR e 45 viviam com a família de nascimento. A competência social foi avaliada junto dos próprios adolescentes através do SSIS-RS. Os resultados demonstraram diferenças estatisticamente significativas entre os três grupos de adolescentes, apresentando os adolescentes adotados mais habilidades sociais e menos problemas de comportamento que os adolescentes em AR, mas menos habilidades sociais e mais problemas de comportamento que os adolescentes que viviam com a família de nascimento. Verificou-se ainda quanto mais tarde os adolescentes que vêm a ser adotados entraram em acolhimento, menor o seu reportório de habilidades sociais. Estes resultados apontam a premência de práticas de intervenção em proteção infantil que propiciem o desenvolvimento da competência social.

Apresenta-se um estudo exploratório com 307 estudantes de instituições de ensino superior do Porto. Os participantes de ambos os sexos, com idades entre os 18 e os 48 anos (M = 23; DP = 5.6) responderam a um questionário de diagnóstico local de segurança, a fim de captar as perceções sobre o crime e a vitimação na área, os sentimentos de segurança e as conceções sobre a atuação policial. Os resultados apontam para uma perceção geral de segurança, apesar dos roubos ou dos peditórios reportados. A experiência de vitimação (15%), nem sempre reportada às autoridades, traduziu-se numa perceção fragilizada quanto à atuação policial. O estudo permite concluir pela importância da formulação estratégica de planos de segurança baseada numa participação da comunidade.

Ocean waves is one of the ocean phenomenon and It is occurred by the external forces. There are some approaches to study this phenomenon which are analytical, numerical, and physical modelling. This research aims to compare between analytical and experimental data. The methods were used in the research divided into three steps. First step was calculating theoretical equation of the relationship between dimensionless number of relative depth (kh) and stroke and wave height ratio (H/S). Secondly, the wave parameters including wave height (H), water depth (d), and wave length (L) were measured in a wave flume. Finally, the value of percentage model bias (PB) was calculated. It showed at 15,513% and 8,5% for 50 rpm and 80 rpm, respectively. In conclusion based on PB, experimental data had positive correlation to analytical equation. Keywords: Waves, piston type wavemaker, percentage model bias (PB)  Gelombang merupakan salah satu fenomena yang ada di laut.

On the Standard Aversion to the Agrapha Dogmata
Authors: Szlezák Thomas A.
Published: June 2018

The present paper deals with eight charges that are frequently leveled against any research that focuses on the agrapha dogmata. The charges are demonstrated to be completely unfounded and, therefore, duly dismissed. In particular, it is argued here that the phrase ta legomena (so‑called) is by no means to be understood as ironic. Consequently, the article rejects the very common picture of Plato as some sort of dogmatist and author of a fixed philosophical system. However, Plato’s philosophy is presented as rather ‘overt’ and ‘straightforward’ in its nature. With the situation being as it is, thorough knowledge of the agrapha dogmata is shown to be an absolute prerequisite for understanding Plato’s dialogues. The paper concludes with an observation that while investigating the issue is completely warranted and does not in any way entail any devaluation of the dialogues, Aristotle’s testimony must also be taken into account.
Socrates’ Philosophy as a Divine Service in Plato’s Apology
Authors: Tymura Dorota
Published: June 2018

The aim of the present paper is to discuss Socrates’ idea of philosophy asa service to the god. First the article investigates why Chaerephon wentto Delphi and why he asked Pythia the famous question concerningSocrates. The investigation provides a basis for distinguishing two majorperiods in his activity. The one preceding the Delphic oracle consists inconducting inquiries in a group of closest friends. The one following theDelphic oracle consist in addressing a much larger audience. An analysisof both periods suggests that the oracle from Delphi greatly affectedSocrates’ relations with other Athenians. While the present article dealsalso with the issue of Socrates’ daimonion, it hypothesizes that the voiceof daimonion and the voice of Pythia could be regarded as Apollo’sinterventions.
Ancient Greek and Byzantine Political Ethics
Authors: Mantzanas Michail
Published: June 2018

The political morality that Plato and Aristotle supported was governed by various anthropological and social determinants, which means that they focused on man understood as a citizen and interpreted through the dialectic as well as through the prospects of the city’s happiness, since for both of them man was a social animal. The political ethics of Plato and Aristotle does not endanger the political community with political bankruptcy. This political morality does not start from intransigent principles to reach a compromise that has already been surpassed by the previous negative dynamics. The Byzantine political morality oscillates between the individual and the totality. It is not governed by individualism but rather by communitarianism, which entails that it confirms the dynamics of unity within the city. The Byzantine political morals is imbued with an anticipation of the political crisis, it seeks to identify any negative developments and strives to avoid the political marginalization of the citizens who are likely to rebel against any autocratic government. The Byzantine political morality is, thus, not an idle and selfish political introversion, concerned merely with political crises, conflict scenarios and conspiracy theories, as it strives to come up with various solutions that should guarantee political balance.
Good, Pleasure and Types of Friendships in Aristotle’s Eudemian Ethics
Authors: Smolak Maciej
Published: June 2018

In EE H 2 Aristotle presents a typology of friendship starting from the puzzle whether the good or the pleasure is the object of love. But after indicating the reasons for loving and identifying three types of friendships he raises three important questions (1237a19–21): (1) whether there is any friendship without pleasure; (2) how the hedonical friendship differs from the ethically friendship; (3) on which of the two things the loving depends: do we love somebody because he is good, even if he is not pleasant, at any rate not for his pleasantness? The present article attempts to give answers to questions 1–3 and show that despite the coincidence of good and pleasure and the important role of pleasure in the hedonical and ethical friendship the typology does not lose its validity
Thales on Water
Authors: Legutko Ryszard
Published: June 2018

The paper attempts to reconstruct Thales’ argument about water, which is rightly considered to be the core of his philosophy of nature. It consists of two separate arguments – one biological and the other physical – which ascribe to water two different functions: in the first case, it is a source of life on the earth or, in another version, a source of life of the earth in its entirety; in the second case, it is something that supports the earth in its stationary position in the cosmos. These two arguments indicate that Thales’ notion of water was meant to answer more than just one question about nature. This, in turn, might justify the use of the concept of arche, which Aristotle attributed to the Ionian philosophers, even though Thales had obviously never used the term. The concept may somehow accurately render Thales’ more general view of water. It should be noted, however, that if the term arche can be applied to Thales’ views, then it is only in the sense related to the “coming-to-be”. Thales’ arguments did not apply – contrary to what some doxographers said and what certain scholars still maintain – to the question of the end, or perishing of physical things, the problem taken up only by later Ionians. To put it differently, Thales never claimed that the physical things which die or undergo destruction change into water.
Melissus and the Problem of the Void: Apology and/or Misapprehension of the Parmenidean Monism?
Authors: Volpe Enrico
Published: June 2018

With respect to Parmenides’ thought Melissus was regarded as a dissident thinker already in antiquity. His polemical introduction of the concept of void and the relative idea of infinite Being seemed particularly controversial. The aim of the present paper is to examine the origins of the Melissian understanding of void in order to trace its philosophical genesis to the criticism of the Atomist Leucippus. According to the philosopher from Abdera, the Eleatic fundamental principles had to conform to the obviousness of bodies’ motion, which is why the Eleatic not-Being had to be understood as void. Melissus took issue with this view and criticized the idea of the void’s reality by means of a methodical argument. In the course of doing so, the philosopher from Samos distorted the original Parmenidean ontology, which is why his theories were often criticized severely as theoretically weak.
Trilemmas: Gorgias’ PTMO Between Zeno and Melissus
Authors: Rossetti Livio
Published: June 2018

The present paper makes the following points. (1) The summary given in Sextus Emp. Math. VII is of much greater value than usually acknowledged, since it preserves several key elements of Gorgias’ communicational strategy. (2) A sketchy trilemma is available in the opening sentence of Philolaos (DK 44B2) as well as in a passage of Plato’s Parmenides. This is evidence in favor of the hypothesis that the very first known trilemma was devised by Gorgias and not by Sextus himself or Aenesidemus. (3) Not unlike Zeno, Gorgias enjoyed to be neither serious nor joking, but remained somewhat halfway. This point is seldom acknowledged, though it is crucial in order to understand that he pretends to claim (e.g. that p), but his claims do not amount to any points of doctrine. (4) That he remains halfway should not prevent us from appreciating some of his ideas, but, at the same time, we should not expect full intellectual adhesion to what he tells us. Besides, something similar occurs in most of Plato’s dialogues. (5). Gorgias owes a lot to Melissus.
Effect of thermal modification on the micromorphology of decay of hardwoods and softwoods by the white rot fungusPycnoporus sanguineus
Authors: Gao Jie , Kim Jong Sik , Daniel Geoffrey
Published: June 2018

Thermal modification (TM) of wood at high temperatures can lead to significantly improved decay resistance against white rot (WR) fungi, but little is known about the mechanism of this improvement at the cellular level. As a contribution to this topic, hardwoods (HWs) (ash, beech) and softwoods (SWs) (spruce, fir) were submitted to the Termovuoto®TM process at 220°C for 3–4 h (shortly TMW220°C) and were degraded by the WR fungusPycnoporus sanguineus.The results were studied using microscopy techniques. Decay occurred preferentially via cell wall delignification prior to the removal of cellulose and hemicelluloses. Concerning this effect and fungal colonization, there were no essential differences between TMW220°Cand the unmodified reference of all wood species. TMW220°C, however, showed a number of characteristic changes in decay morphology. Narrow and distinct concentric transition zones were observable in decayed fiber and tracheid cell walls, which demark the lignified and delignified regions. Moreover, cell wall separation by preferential delignification of compound middle lamellae (CML) was not seen in decayed tracheids. It can be concluded that the Termovuoto TMW220°Cprocess has an impact on the delignification process ofP. sanguineusat the cell wall level, which slows down the decay.
