Light Scattering in the Eye Lens Near the Spinodal
Authors: Grzegorzewski Bronisław , Rudeichuk Volodymyr
Published: August 2018

Scattered light intensities measurements of the nuclear part of adult bovine lenses are reported. In the investigated samples the existence of a binary liquid phase separation from a metastable state is demonstrated by the phenomenon of hysteresis. Fluctuations near spino­dal are studied by means of a tentative theoretical approach. Accordingly the scattered light intensities were analyzed reduced by the intensity obtained for the stable state of the system. Fluctuations in the stable state are ascribed to protein aggregates and are analyzed by means of random density fluctuation theory. To evaluate the correlation length of the fluctuations near spinodal the Ornstein-Zernike theory is adopted. Temperature dependence of the corre­lation length ξ of the fluctuations near spinodal can be described by equation for critical fluctuations

. For the investigated lenses the exponent ν varies from 0.65 to 0.74 and the parameter ξ0 varies from 1.6 nm to 3.6 nm. The spinodal temperature Ts for the investigated samples is evaluated.

Authors: Budzikiewicz Herbert , Fernández Diana Uría , Fuchs Regine , Michalke Roland , Taraz Kambiz , Rungiviriachai Chalerm
Published: August 2018

For a pyoverdin isolated from Pseudomonas putida it could be shown that Lys is incorporated into the peptide chain by its ε-amine group in contrast to the normally observed connection by the α-amino group. The structure elucidation of the pyoverdin by chemical degradation and spectroscopic methods is reported and the criteria for the distinction between α-and ε-connection in the case of Lys are discussed.
Chemo-Enzymatic Syntheses of Both Enantiomers of Neodictyoprolenol and Neodictyoprolene; Possible Biosynthetic Intermediates of Sex Pheromones in Brown Algae
Authors: Yamamoto Yuuko , Akakabe Yoshihiko , Matsui Kenji , Shimidzu Hiroshi , Kajiwara Tadahiko
Published: August 2018

Neodictyoprolenol [(-)-(S)-(1,5Z,8Z)-undecatrien-3-ol], dictyoprolenol [(-)-(S )-(1,5Z)- undecadien-3-ol] and their acetates neodictyoprolene [(+)-(5)-3-acetoxy-(1,5Z,8Z)-undecatriene] and dictyoprolene [(+)-(S)-3-acetoxy-(1,5Z)-undecadiene], which are interesting as possible biosynthetic intermediates of the sex pheromones (dictyopterene B, C′ and D′) of brown algae, were synthesized by chemo-enzymatic methods through optical resolution of racemic neodictyoprolenol and dictyoprolenol using two lipases; Amano PS (Pseudom onas sp.) and Novozym 435® (Candida sp.). A combination of acylation of the alcohols and hydrolysis of the acetates by Novozym 435® produced neodictyoprolenol, neodictyoprolene, dictyoprolenol and dictyoprolene with high optical purities over 99% enantiomeric excess (e.e.).

This snythetic methods will make it easier to search these compounds in marine algae and to study their biosynthesis.
New Auxin Analogs. Possible Probes for Auxin Receptors
Authors: Reynoso-Herrera Elvia , Rius-Alonso Carlos , Albores-Velasco Martha
Published: August 2018

Based on structure-activity relationship studies, auxin analogs that can be covalently bound to a polymeric support are proposed. Molecular modeling studies were carried out by comparing different parameters of substituted phenoxyacetic acids with their auxin activity. A good correlation of the activity with the size and shape of the HOMO orbital of the acids was found. Accordingly, analogs with a substituent in the 5 position of the aromatic ring, capable to be bound to a polymeric matrix were synthesized and their auxin activity was evaluated with the wheat coleoptile elongation test. Compounds with a hydroxymethyl- and with a carboxymethyloxy- substituent were active in this test. Their use as probes for the 2,4-D receptor is proposed.
Carboxymethylated Glucan Inhibits Lipid Peroxidation in Liposomes
Authors: Babincová Melánia , Machová Eva , Kogan Grigorij
Published: August 2018

Protective capabilities were studied of carboxymethylated (1→3)-β-ᴅ-glucan from Saccharomyces cerevisiae cell wall against lipid peroxidation in phosphatidylcholine liposomes in duced by OH· radicals produced with Fenton’s reagent (H2O2/Fe2+) and also by microwave radiation using absorption UV-VIS spectrophotometry. A significant decrease in the conjugated diene production, quantified as Klein oxidation index, was observed in the presence of a moderate amount of added glucan. Increase of the oxidation index was accompanied with enhanced carboxyfluorescein leakage as a result of liposome membrane destabilization. This process was markedly suppressed with glucan present in the liposome suspension. Therefore, glucan may be considered as a potent protector against microwave radiation-induced cell damage.

Bacteriorhodopsin Thermal Stability: Influence of Bound Cations and Lipids on the Intrinsic Protein Fluorescence
Authors: Tuparev Nikolai , Dobrikova Anelia , Taneva Stefka , Lazarova Tzvetana
Published: August 2018

Temperature - induced changes in protein intrinsic fluorescence of native, delipidated and deionized purple membranes are investigated. It is found that the removal of cations most strongly affects the protein and its thermal stability. The denaturation of dei-BR completes at 70 °C, while delipidated and native BR still maintain their native structure at this temperature. Both, the quantum yield and the fluorescence maximum suggest correlation between the Trp-retinal coupling and protein structural stability. The low red shift of the fluorescence maximum caused by increasing of temperature indicates limited unfolding of bacteriorhodopsin upon denaturation.
Hydration of Alkylammonium Salt Micelles - Influence of Bromide and Chloride Counterions
Authors: Róźycka-Roszak Boźenna , Żyłka Romuald , Sarapuk Janusz
Published: August 2018

The micellization process of dodecyltrimethylammonium chloride (DTAC) and bromide (DTAB) was studied. Nuclear magnetic resonance method was used. The 1H NM R and 13C NM R spectra were taken at higher and lower concentrations than the critical micelle concentrations (CMC) of the compounds studied. Chemical shifts were analysed. The studies performed were prompted by earlier calorimetric measurements which showed that there were significant qualitative and quantitative differences in the micellization process of the compounds studied. Namely, DTAB micelle dissociation was found to be an endothermic process while that of DTAC was exothermic. The differences found must be the result of differentiated influence of bromide and chloride counterions on the micellization process, including the phenomenon of micelle hydration. The objective of the work was to check whether cationic surfactant counterions can influence the micelle hydration process. Indeed, DTAB and DTAC, as monomers, exhibit similar hydrophobic hydration, but DTAB micelles are more hydrated than DTAC ones.

It seems that the differences found in micellization of both salts studied may be attributed to different physicochemical properties of bromide and chloride ions, such as their mobilities and radii of their hydrated forms. Moreover, the effect of anions on the water structure must be taken into account. It is important whether the anions can be classified as water ordering kosmotropes, that hold the first hydration shell tightly, or water disordering chaotropes, that hold water molecules in that shell loosely.
Expression of an HSP110 Family, Ischemia-Responsive Protein (irp94), in the Rat Brain after Transient Forebrain Ischemia
Authors: Koh Hyeon-Song , Moon Il Soo , Lee Young-Ho , Shong Minho , Kwon O-Yu
Published: August 2018

The transcriptional expression of an ischemia responsive protein (irp94) in the hippocampus of rats was analyzed by Northern blotting. A transient forebrain ischemia was induced in the rats by temporary occluding of the bilateral common carotid arteries (CCAs) for various periods, and then reperfusion. Among the frontal, parietal, temporal and occipital lobes, and the cerebellum and hippocampus, the maximum mRNA expression of irp94 was at the occipital lobe, and the minimum was at the parietal lobe following ten min of forebrain ischemia. The irp94 mRNA expression reached a maximum fifteen min after the transient ischemia. From twenty min on after the ischemia its expression decreased. After a ten-min ischemia and the following reperfusion, irp94 mRNA expression gradually increased in the first twelveh, and then decreased. The expression pattern was like that of the endoplasmic reticulum chaperone, Erp72, but not that of the cytosol chaperone, hsp72. In addition, when intracellular ATP was depleted with antimycin A the mRNA level of irp94 increased in a thyrocyte cell culture model.

The results suggest that irp94, like a molecular chaperone, may play a role in protecting the cell against external stimulation, especially after a transient forebrain ischemia. Although future studies of irp94 will be required to clarify the interactions with other intracellular factors inducing ischemia or showing molecular chaperone activity, what is offered here is an insight into its functional role as a component of stress response in neurons that should be considered as a new therapeutic approach for the treatment of ischemia.

Morir de pie. Una aproximación a los derechos humanos a partir de dos novelas latinoamericanas
Authors: Guaraglia Pozzo Malvina
Published: August 2018

El artículo plantea la posibilidad de leer los derechos humanos desde una perspectiva cultural, haciendo hincapié en su dimensión ética, como herramientas de construcción de identidades políticas y sociales. Desde esta premisa, y partiendo de un campo nuevo de estudios, se postula la existencia de una larga genealogía de textos de denuncia que han articulado los principios éticos de los derechos humanos en los espacios públicos nacionales de las sociedades latinoamericanas. Asimismo, a través del análisis ejemplificativo de dos novelas, se estudian las distintas estrategias retóricas que pueden estar en la base de esa articulación.

Un nuevo orden en la locura: estructuras disipativas en Desde los blancos manicomios, de Margarita Mateo Palmer
Authors: Lugo Herrera Lilianne
Published: August 2018

El presente trabajo propone analizar la novela Desde los blancos manicomios, de la autora cubana Margarita Mateo Palmer, a partir de algunos conceptos del mundo de la ciencia, tales como las estructuras disipativas de Ilya Prigogine, la Ley de la Entropía, y los fractales de Benoit Mandelbrot. Dicho análisis permitirá mostrar cómo el diseño de la protagonista y su característica principal, la locura, así como la estructura fragmentada de la novela, las diferentes voces narrativas y el juego intertextual, permiten una lectura crítica y feminista de la literatura cubana y caribeña. La locura de la protagonista, además, se puede ver como la expresión de un desorden social y un mundo fracturado, que en este caso coincide con la realidad cubana de las décadas de los 90 y los 2000, años de profunda crisis económica tras la caída de la Unión Soviética y el campo socialista, y como una reacción de búsqueda de agencia intelectual femenina frente a una sociedad machista.

Making the Science Classroom a Place for Wonder
Authors: Niedermeyer Jason
Published: August 2018

What is the role of wonder in a classroom? And how does a teacher activate this most human of emotions? This paper investigates the role wonder—and the subjects most closely associated with it, art and science—should play in our students’ school lives. The work connects my lived experiences as a high school teacher and college professor with the philosophy of John Dewey and contemporary literature on pedagogical practices. My findings suggest that it is a moral imperative to encourage wonder in our classrooms and to do so in an authentic way.
How to Use Taxonomic Principles in a Non-Scientific Setting to Teach Hierarchical Thinking
Authors: Rehorek Susan J. , Shotwell Mark A.
Published: August 2018

Science education as it is taught in the twenty-first century primarily focuses on scientific literacy, specifically on the process of science and how it can be applied. Most process-driven pedagogical tools are based on hypothesis-driven science, in which the hypothesis is the focal point. In descriptive science, the focal point is the organization of data, leading ultimately to the formation of questions and hypotheses. This technique helps students through the process of data collection, organization, and application without the use of scientific terminology. The students are led through the process using common objects, and then required, as a homework assignment, to collect, organize, and apply their own data. By using this simple, repetitive technique, students will see how a classical scientific field (taxonomy) can be applied to modern life situations.
Using Open-Source Data in Correlative Species Distribution Modeling of Marine Species
Authors: Morales-Ramirez Carlos A. , Pang Pearlyn Y.
Published: August 2018

Open-source data are information provided free online. It is gaining popularity in science research, especially for modeling species distribution. MaxEnt is an open-source software that models using presence-only data and environmental variables. These variables can also be found online and are generally free. Using all of these open-source data and tools makes species distribution modeling (SDM) more accessible. With the rapid changes our planet is undergoing, SDM helps understand future habitat suitability for species. Due to increasing interest in biogeographic research, SDM has increased for marine species, which were previously not commonly found in this modeling. Here we provide examples of where to obtain the data and how the modeling can be performed and taught.
Challenges to Meeting the UN Sustainable Development Goals in Sri Lanka
Authors: Herath Gamini
Published: August 2018

In 2015, the UN proposed the Sustainable Development Goals; they were accepted by 193 countries. Sri Lanka faces many challenges in implementing the SDGs. The lack of reliable and recent data is a serious issue. Another issue is the weak institutional capacity of Sri Lanka, which has led to poor governance and policy incoherence. There is no strong political will, and interministerial conflicts are rampant. Unless these issues are properly addressed, the yahapalanaya (good governance) government of President Sirisena may not contribute well to achieve the SDGs by 2030.
Climate and wartalk: Metaphors, imagination, transformation
Authors: Mangat Rupinder , Dalby Simon
Published: August 2018

Fossil fuel divestment activists re-imagine how the war metaphor can be used in climate change action to transform thinking around what will lead to a sustainable society. Through the naming of a clear enemy and an end goal, the overused war metaphor is renewed. By casting the fossil fuel industry in the role of enemy, fossil fuel divestment activists move to a re-imagining of the climate change problem as one that is located in the here and now with known villains who must be challenged and defeated. In this scenario, climate activists move away from the climate and national security framing to a climate and human security way of thinking.
Oncogenic kinases and perturbations in protein synthesis machinery and energetics in neoplasia
Authors: Uchenunu Oro , Pollak Michael , Topisirovic Ivan , Hulea Laura
Published: August 2018

Notwithstanding that metabolic perturbations and dysregulated protein synthesis are salient features of cancer, the mechanism underlying coordination of cellular energy balance with mRNA translation (which is the most energy consuming process in the cell) is poorly understood. In this review, we focus on recently emerging insights in the molecular underpinnings of the cross-talk between oncogenic kinases, translational apparatus and cellular energy metabolism. In particular, we focus on the central signaling nodes that regulate these processes (e.g. the mechanistic/mammalian target of rapamycin MTOR) and the potential implications of these findings on improving the anti-neoplastic efficacy of oncogenic kinase inhibitors.
Role of RFRP-3 in the development of cold stress-induced polycystic ovary phenotype in rats
Authors: Squicciarini V , Riquelme R , Wilsterman K , Bentley G E , Lara H E
Published: August 2018

RFamide-related peptide (RFRP-3) is a regulator of GnRH secretion from the brain, but it can also act in human ovary to influence steroidogenesis. We aimed to study the putative local role of RFRP-3 in the ovary and its potential participation in the development of a polycystic ovary phenotype induced by chronic sympathetic stress (cold stress). We used adult Sprague–Dawley rats divided into control and stressed groups. In both groups, we studied the effect of intraovarian exposure to RFRP-3 on follicular development and plasma ovarian steroid concentrations. We also tested the effect of RFRP-3 on ovarian steroid production in vitro. Chronic in vivo intraovarian exposure to RFRP-3 decreased basal testosterone concentrations and cold stress-induced progesterone production by the ovary. In vitro, RFRP-3 decreased hCG-induced ovarian progesterone and testosterone secretion. Immunohistochemistry and mRNA expression analysis showed a decrease in Rfrp and expression of its receptor in the ovary of stressed rats, a result which is in line with the increased testosterone levels found in stressed rats. In vivo application of RFRP-3 recovered the low levels of secondary and healthy antral follicles found in stressed rats. Taken together, our data indicate a previously unknown response of hypothalamic and ovarian RFRP-3 to chronic cold stress, influencing ovarian steroidogenesis and follicular dynamics. Thus, it is likely that RFRP-3 modulation in the ovary is a key component of development of the polycystic ovary phenotype.

Authors: Nahata Leena , Campo-Engelstein Lisa T. , Tishelman Amy , Quinn Gwendolyn P. , Lantos John D.
Published: August 2018

In this article, we discuss a case in which a 16-year-old birth-assigned male came out to her parents as transgender. She is referred to the gender management program at a large pediatric academic center to discuss hormone therapy. She was initially evaluated by a psychiatrist, diagnosed with gender dysphoria and anxiety, and treated with medication and psychotherapy. When her anxiety was well controlled and she met eligibility and readiness criteria, she was referred to 1 of 2 pediatric endocrinologists in the gender management program to discuss hormone therapy. As part of the discussion about the risks/benefits of estrogen therapy, the pediatric endocrinologist discussed options for fertility preservation (FP) before potentially gonadotoxic therapy. The patient stated that she was not interested in FP. Her mother requested procedures to preserve the possibility that the daughter could have biological children someday. We asked experts in the care of transgender youth to discuss ways in which the doctor could respond to this disagreement between parents and a teenager about FP.

RUSSIA'S MARKET AND PRODUCT-BASED EXPORT DIVERSIFICATION
Authors: ERKAN Birol , Sunay Zekai Fatih
Published: August 2018

The Gini-Hirshman Index, Trade Concentration Ratio and Deviation Index has been used as the main measurement tools in this study. In the study, Russia has been analyzed in terms of market and product-based export diversifications between 2000-2016. Scores obtained at the end of the analyzes made reveal that the diversification of Russian exports is low on both market and product basis. It is obvious that high level of export concentrations will adversely affect the Russian economy. It is likely that Russia, which can not diversify its exports on a market and product basis will be influenced by the global crisis.

ABSTRACT Objective: To report the insertion of the nursing students of the Franciscan University Center in the community through the project Adopting a Family, contributing to critical thinking within the Nursing academic production and its articulation to collective health. Results: In the professors’ evaluation, the activity represented an effective articulation and insertion of the university in the community; for the students, it allowed for spaces of construction, deconstruction and negotiation with the unknown and the uncertain; for the families, it enabled the feeling of being remembered and valued as human beings and citizens. Through the experiences had, the transformation of health practices goes through the emergence and valuation of new knowledge. Final considerations: The insertion of the university in the community is constituted by an entrepreneurial strategy that is proponent of changes, due to its more effective and resolute outreach of health issues proposed by the national health system.
The professor’s body: discourses on subjectivity to reflect on nurses’ education
Authors: Silva Paulo Sérgio da , Figueiredo Nébia Maria Almeida de
Published: August 2018

ABSTRACT Objective: to reflect on the body of the nursing professor in the subjectivity discourse. Method: this is a reflective essay on the theoretical and practical reverberations of the nursing professor’s body based on the Deleuzoguattarian discourse. Results: in the theoretical framework, the body of the nursing professor was considered as a producer of subjectivities and understood without organs, surrounded by strengths, desires, and affections. In the practical framework, we discussed pedagogical strategies developed by professors, such as dramatic games, simulated scenes, presentation of the line of care and living portfolio, characterized by stimulating nursing students to value political, civic, creative, and supportive dimensions. Conclusion: based on the subjectivity discourses, the professor’s body was demystified as uniquely holder of knowledge, and all participants in the educational scenario were considered active protagonists of collective knowledge.

Molecular studies on African swine fever virus from Brazilian isolates
Authors: Freitas Tânia Rosária Pereira , Lyra Tânia Maria de Paula
Published: August 2018

ABSTRACT: African swine fever (ASF) is a devastating viral infirmity that affects domestic and wild swine caused by the ASF virus (ASFV) that belongs to the family Asfaviridae in the Asfavirus genus. Studies for genotypic and antigenic determination of ASFV including samples from Brazilian outbreaks were carried out outside Brazil. Here, we have reviewed studies on the molecular aspects of Brazilian isolates from 1978 and 1979. Results obtained from restriction fragment analysis, cloning and gene sequencing display the genotypic variation of viral samples. Viral genotyping based on sequences of the 3’ region of the p72 gene included in genotype I Brazilian samples, reinforcing the suggestion of the European origin for the virus that infected Brazilian herds and having low virulence potential. Corroborating those findings, at the American station PIADC, the infection of healthy pigs with the Brazilian strain induced ASF sub acute disease with low mortality and a low-virulence. Those results were similar with epidemiological vigilance forms of Brazilian swineherd in good health conditions having at least one ASFV isolation, and the ASF pioneer’s studies on the low mortality in the Brazilian herds affected by ASF. The ASFV spreading in Eastern Europe and Russia triggered a greater concern with intensifying the risk of viral dissemination from country to country. The low virulence ASF strains can increase the problem because of hidden viral reservoirs - which further reinforces the need for safety and preventive measures in virus-free countries. Finally, the problem is further compounded by the lack of vaccines and other immunological resources.
Evaluation of microscopic protocols for somatic cell counts in milk of dairy sheep
Authors: Moraes Cristiane Rosa , Vieira Tatiana Regina , Pinto Andrea Troller , Schmidt Verônica
Published: August 2018

ABSTRACT: The somatic cell count (SCC) is a diagnostic tool that indicates the mammary gland health and can be determined by the counting of cells in the microscope. There are discussions regarding appropriate staining method to the ewes’ milk. The present study aimed to identify a methodology of microscopic SCC proper to the milk of the ovine species. Therefore, glass slides for smear were manufactured with 10 µL of ewe’s milk in 1 cm2, and the fixers xylol and Carnoy’s solution were tested, as well as and May-Grünwald, Broadhurst-Paley, Wrigth and Panoptic stainings. Carnoy’s solution was elected, because it allowed a better fixation of the dairy film to the microscope slides, and Broadhurst-Paley staining, due to its good coloration and visualization of cells, as well as the differentiation of cytoplasmic corpuscles in ewe’s milk. Broadhurst-Paley coloration is a tool applicable to the somatic cell count in ovine specie’s milk.

ABSTRACT: This study aimed to evaluate the occurrence of Bacillus cereus group in requeijões and especialidades lácteas tipo requeijão (regular and light) and to verify if there is differences in relation to this occurrence among different categories of these products. A set of 14 (35%) lots was contaminated with this bacterial group from the 40 lots with low counts (maximum 3.1 × 10 CFU/g), and no significant difference regarding counts or presence/absence were observed among the categories of the products. It can be concluded that contamination by B. cereus group in these products is unable to consist in risk to consumers, regarding adequate refrigeration during selling. This study was the first one to report this bacteria group for these dairy products and highlights the needs of further investigations to evaluate the impact of its spoilage during shelf life.

Abstract OBJECTIVE Randomized clinical trial protocol to evaluate the incidence of radial artery occlusion with two different arterial compression devices after transradial procedures. METHODS Barbeau’s test will be performed in adults scheduled to undergo transradial interventional procedures. Those with A, B, or C plethysmographic patterns will be selected. At the end of the procedure, patients will be randomly assigned (1:1) to receive patent haemostasis with TR Band™ device or conventional haemostasis with an elastic adhesive bandage. The primary outcome is the incidence of radial artery occlusion. Secondary outcomes are Barbeau’s test curve change, additional time to achieve haemostasis, incidence of bleeding at the puncture site, pain severity, development of arteriovenous fistula, radial pseudo aneurysm, any access-site complication requiring vascular surgery intervention and costs between the two devices. DISCUSSION The results of this trial should provide valuable additional information on the best approach for haemostasis after transradial percutaneous cardiovascular interventions.

ABSTRACT In order to reach an optimum and sustainable production, growers must know the fertilizing potassium (K) and phosphorous (P) application rates. The present study aimed to determine the rice development in response to combined rates of P and K, on Plinthaquults (380-400 g kg-1 of clay), under high and low fertility conditions, in the tropical lowland plain of the Araguaia river, Brazil. Three field experiments were performed, each one consisting of a completely randomized factorial block design, with three replications. Treatments included a combination of six K2O rates (0 kg ha-1, 30 kg ha-1, 60 kg ha-1, 90 kg ha-1, 120 kg ha-1 and 150 kg ha-1) with six P2O5 rates (0 kg ha-1, 30 kg ha-1, 60 kg ha-1, 90 kg ha-1, 120 kg ha-1 and 150 kg ha-1). No interaction effect between P and K rates was observed for the evaluated variables in any fertility level/year. Phosphorous application under low fertility conditions, as well as K under high fertility conditions, affect overall crop nutrition, tillering capacity, yield components and grain yield of lowland rice, though no effects were observed due to the P application in high fertility soils and K in low fertility soils. Under high fertility conditions, the grain yield increment rate due to the K application was 4.04 kg ha-1, whereas in the low fertility areas, such as recently cleared fields, a maximum yield of 7,161 kg ha-1 was achieved by applying 140 kg ha-1 of P.

Abstract Objective: To grasp the perceptions and experiences of professionals in the primary health care as teamwork in the Family Health Strategy (FHS) in a medium-sized municipality in the southern of Brazil. Method: Qualitative research carried out, between April and July 2016, with 13 health professionals (nurses, doctors, dentists, community health agents, nursing technicians and oral health aide) workers in FHS. Data were collected through semi-structured interviews, transcribed and submitted to content analysis. Results: From the analysis emerged three thematic categories: Teamwork from the perspective of the FHS health professionals; Strategies for maintaining teamwork out of daily routine; and Challenges of the insertion of Oral Health in the FHS. Conclusions and implications for a practice: Participants demonstrated that they understood the importance of teamwork and interpersonal relationships, and recognize the inherent challenges of this process. They revealed weaknesses in the relationships among dentistry and other members of the FHS, marked by a sense of exclusion and disinterest in participating.

Published: August 2018

Resumo Este artigo se propõe a discorrer sobre algumas das principais definições de qualidade aplicadas à educação superior a partir dos anos 1990, tanto por autores brasileiros quanto estrangeiros, de modo a elucidar o dissenso presente no tema e dispor de uma definição da “qualidade” em relação à educação. Para alcançar tais objetivos, esta pesquisa se utilizou de metodologia qualitativa de cunho descritivo, possibilitada por um estudo bibliográfico de diversas fontes, principalmente artigos científicos sobre o tema da qualidade na educação superior. Como resultado, constatou-se uma composição multidimensional de qualidade que aborda tanto características instrumentais, presentes em fatores objetivos e regulatórios, quanto substantivas, pautadas em elementos subjetivos e simbólicos, quando aplicada na educação superior. Também foram observadas diferenças paradigmáticas entre as abordagens brasileiras e estrangeiras, apresentando a qualidade uma ênfase teórica no contexto brasileiro e uma abordagem prática no contexto estrangeiro.

Resumo El objetivo de este ensayo es investigar las diferentes dimensiones formativas que los docentes del siglo XXI necesitan potenciar para transformar su realidad socioecológica, con el fin de repensar las políticas públicas educativas del Ecuador. Primero se abordan las concepciones epistemológicas de la educación transdisciplinar: la autoformación, la heteroformación, la ecoformación y la ontoformación. Después se complementa con los saberes ancestrales absolutos y alter-nativos. Como resultado, las ciencias de la educación para el buen vivir emergen como una praxis pedagógica transformadora a nivel ontológico, ético, estético, político y científico. En conclusión, el artículo integra un diálogo inter-epistemológico que conjuga una ecología de saberes para la articulación de una educación del buen vivir que emancipe, concientice y sensibilice.
The training of the teacher in the 21th century: an approach with the history of medieval education
Authors: Oliveira Terezinha
Published: August 2018

Abstract Our purpose is to deal with teacher education in Brazil, with the history and history of education as our guiding principle, based on texts by Thomas Aquinas. For us, in the process of teacher training, the professionals involved must be clear that teaching and learning occur when these characters are aware of the need to understand the intellectual “essence” of man. Therefore, we recover the Dominican master to make explicit that knowledge becomes effective when there is an understanding that men are, par excellence, social beings. Based on these principles, we will examine data about teaching in Brazil, relying on the reflections of the medieval master to show the relevance to a country whose people have knowledge acquired by and in history. In theoretical terms, our arguments follow the principles of social history, with special attention to the idea of long duration.
Multilevel modeling of persistence in higher education

Abstract The dropout or evasion rates in higher education are now a social and institutional concern, justifying the implementation of public policies to prevent this phenomenon. These policies need studies on the most determinant variables of the risk of dropout. The main objective of this study is to analyze the student’s persistence in undergraduate courses, and the relationship with the student’s previous school trajectory and with the conditions of entrance into higher education, controlling for students’ sociodemographic characteristics, such as gender and age. We applied multilevel logistic regression models to data of 2.697 freshmen enrolled in a Portuguese public university in the academic year 2015/16. The results suggest that failure in basic education (ISCED 2) has a long-term effect. According to the estimates obtained, students who declare not having failed in basic education have odds ratio of persistence 2.7 times higher than students who declare having failed in basic education. The conditions of student’s admission to the course he/she attends are relevant variables to persistence in Higher Education, for example, whether s/he was admitted to her/his first option course and the student’s university entrance score. The results also show that older and male students have lower probability of persistence.
