Velocidad y desorientación en Punctum de Martín Gambarotta y Silvia Prieto de Martín Rejtman
Authors: Ceresa Constanza
Published: July 2014

Martín Gambarotta’s collection of poetry, Punctum (1996), and Martín Rejtman’s film Silvia Prieto (1999) are significant examples of the cultural transformations that took place in Argentina during the 1990s. Both works show the effects of market logic in social space, speech and on new subjectivities. However, this article proposes that the emancipatory character of Punctum and Silvia Prieto goes beyond the mere ‘exposure’ of the corrosive effects of neoliberalism in everyday life. By way of an analysis of certain scenes and poems, this article will discuss how, by taking a critical position ‘within’ present social relations of production (and therefore, their mediations), these works reveal a critique of neoliberalism through an ‘economy of language’ that frustrates mercantile logic, by submitting its rapid mediations to the effects of anti-narrative.
Manoel de Barros in film: The nature of language and the language of nature
Authors: Müller Adalberto
Published: July 2014

My concern here is to discuss three adaptations of Brazilian poet Manoel de Barros’ work to cinema: Joel Pizzini’s (1986) prizewinning Caramujo-Flor, my own short Wenceslau e a árvore do gramofone (2008) and Pedro César’s documentary Só dez por cento é mentira (2008). I use the word ‘adaptation’ ironically, because actually the three films are everything but adaptations. They are rather ‘devices’ created to somehow ‘read’ and interpret Manoel de Barros’ poetry in cinematic terms. In doing so, they compel cinematographic language to change its ‘nature’ just as nature compels Manoel de Barros to change his poetry. I also clarify the distinction between poetry and cinema, and expansive terms such as Pasolini’s ‘cinema di poesia’ and Jean Cocteau’s ‘poésie de cinéma’, aiming to illuminate the possible connections between art forms apparently diametrically opposed to one another in the way they function relative to their media. In other words, poetry and cinema can live together as long as some process of intermediality takes place.

Mehr oder weniger?
Authors: Lorenz Stephan
Published: July 2014

»Mehr oder weniger?« Ökologische Wachstumskritik richtet sich gegen zerstörerische Dynamiken moderner Industrie- und Überflussgesellschaften, die ein gutes Leben gefährden. Auch Konzepte nachhaltiger Entwicklung halten oft allzu optimistisch an modernen Mehr-Versprechen fest. Jedoch bietet auch die bloße Hinwendung zum Weniger keine besseren Antworten. Vielmehr bedarf nachhaltige Entwicklung der kontinuierlichen Suche nach abgestimmten Mitteln und Zwecken. Stephan Lorenz zeigt, dass Chancen dafür in der Demokratisierung der Suchprozesse liegen. Den Sozialwissenschaften kommt dabei die Aufgabe zu, zur Verbesserung entsprechender Aushandlungsverfahren beizutragen. Es geht um die Frage: Wer und was muss wie berücksichtigt werden?
Bipositions and motion events: How verb semantics motivates prepositional vs. postpositional uses of Finnish path adpositions
Authors: Lehismets Kersten
Published: July 2014

Finnish is one of the relatively few languages that have bipositions - adpositions that can be used both prepositionally and postpositionally. From a typological point of view, the class of bipositions is quite rare (Hagège 2010: 124). Prepositional and postpositional usages of Finnish bipositions may show remarkable differences, which are not only of stylistic but also of semantic nature. Semantic differences, for instance, may pertain to the opposition between actual and subjective motion. In this article, I discuss constructions containing the Finnish path adpositions (P-ADPs) läpi ‘through’ and yli ‘over, across’ and investigate the semantics of the verbs used in these constructions. I show that semantically more schematic motion verbs prefer postpositions, whereas more specific or contentful ones (such as those that elaborate the motion by emphasizing its incrementality or lack of directionality) prefer prepositions

Measuring Sunk Costs in Agricultural and Food Industry Assets: Why Some Assets Sell Below Appraisal
Authors: Boland Michael A. , Crespi John M. , Turner Tracy M.
Published: July 2014

Asset obsolescence or external obsolescence isa decline in the economic value of capital because ofa decrease in demand for the capital’s services. Measurements of sunk costs typically use appraised values of capital. In food and agricultural industries facing asset obsolescence due to government policy, appraised values may be greatly overstated and this has implications for research on industrial structure. A theoretical model to account for the appraisal error is developed and the method is applied to the U.S. sugar beet industry. The sugar beet industry displays symptoms of asset obsolescence. Our estimates indicate that plant appraisals using currently accepted practices greatly overstated the true value of these assets in 2006.
Enhancement of mechanical properties of polypropylene by blending with styrene-(ethylene-butylene)-styrene tri-block copolymer
Authors: Drozdov Aleksey D. , Sanporean Catalina-Gabriela , de C. Christiansen Jesper
Published: July 2014

Observations are reported in impact tests, uniaxial tensile tests with various strain rates, relaxation tests with various strains and cyclic tests with a mixed deformation program and various maximum strains per cycle on neat polypropylene (PP) and a blend of PP with styrene-(ethylene-butylene)-styrene copolymer (SEBS). Experimental data demonstrate a pronounced enhancement of impact resistance of PP due to the presence of an impact modifier, accompanied by improvement of its properties under low-speed loading, observed as a decrease in relaxation rate and residual strain under cyclic deformation. Material constants in constitutive equations are determined by matching the experimental data. Correlations are established between changes in the viscoelastoplastic response of PP and evolution of its microstructure induced by the presence of an impact modifier.

Published: July 2014

In this study, zinc-62 was prepared at radiopharmaceutical grade (for
62Zn/62Cu generator production) using
natCu(p, xn) reaction with the production yield of
5.9 mCi/μAh
at 30 MeV proton energy (radiochemical
separation yield >95%, radionuclidic purity >99% and
radiochemical purity >99%). In the next step, rituximab was
successively labeled with [62Zn]-ZnCl2 after conjugation
with p-SCN-Bz-DOTA followed by molecular filtration and determination of the
average number of DOTA conjugated per mAb (6:1) by spectrophotometric
method. Radiochemical purity (>97%, measured by ITLC and HPLC),
integrity of protein after radiolabeling (gel electrophoresis) and stability
of [62Zn]-DOTA-rituximab (in final formulation, and human serum)
were determined 1–8 h as well as biodistribution studies in
wild-type rats followed by coincidence imaging for 6 h. However,
the accumulation of the radiolabeled antibody was not consistent with the
former reported rituximab conjugates. [62Zn]-labeled monoclonal
antibodies and fragments can be prepared as potential in vivo PET
generators for molecular imaging however, the search for application of stable
zinc complexes must be continued.
Addition of Al2O3 nanoparticles to bentonite: effects on surface charge and Cd sorption properties
Authors: Mayordomo Natalia , Alonso Ursula , Missana Tiziana , Benedicto Ana , García-Gutiérrez Miguel
Published: July 2014

Compacted bentonite barrier in radioactive waste repositories is expected to prevent radionuclide migration, due to its high sorption capability for many radionuclides. This study analyses whether the addition of Al2O3 nanoparticles (NPs) enhances the sorption properties of bentonite. The study was carried out with 109Cd, highly pollutant heavy metal and divalent fission product. Sorption experiments were conducted in NaClO4 at different ionic strengths (5·10-4 to 10-1 M) and pH (2 to 10), using mixtures of sodium homoionised bentonite and Al2O3 in different proportions.

It has been probed that addition of Al2O3 NPs to bentonite enhances Cd sorption at pH higher than 6. The effect of Al2O3 NPs addition on the surface properties of bentonite colloids was also analyzed by measuring particle size and surface charge in all studied systems.
Interpretation of Knudsen Cell Experiments to determine the Instant Release Fraction in Spent Fuel Corrosion Scenarios by using a Mechanistic Approach: the Caesium Case

Published: July 2014

The Knudsen Effusion Mass Spectrometer (KEMS) and the mechanistic MFPR (Module for Fission Product Release) code are tools which seem particularly interesting to support studies of the Instant Release Fraction (IRF) of Cs from spent nuclear fuel in a final repository. With KEMS, the thermal release of 137Cs and 136Xe were analysed by annealing up to total vaporization (2500K) of high burn-up (60 GWd/tU) Spent Nuclear Fuel (SNF) samples. Powder samples from the centre of the fuel, without high burn-up structure, were used. To determine the IRF, samples were analysed before and after being submitted to corrosion experiments in bicarbonated aqueous media.

MFPR was applied to determine the localization of Cs and fission gases in the SNF at the end of irradiation; the results are compared and supported by dedicated thermodynamics calculations performed for equilibrium conditions at various temperatures and fuel oxygen potentials by the non-ideal thermodynamic MEPHISTA (Multiphase Equilibria in Fuels via Standard Thermodynamic Analysis) database. A possible mechanism for Cs release during thermal annealing is proposed, taking into account inter-granular release and Cs oxide vaporization, atomic diffusion, ternary oxide phase formation and bubble release.

Differences in KEMS release profiles before and after submitting the samples to aqueous corrosion are attributed to the IRF and to changes in the vaporisation mechanism because of differences in the oxygen potential (pO2). The IRF of Cs estimated from the KEMS spectra, consisting on the part located at the grain boundaries and in inter-granular bubbles, is not significantly different from that corresponding to the experimental results found using classical static leaching experiments.

New experimental campaigns are being designed to confirm our interpretation proposed after this first run.
Design of a New Reactor to Work at Low Volume Liquid/Surface Solid Ratio and High Pressure and Temperature: Dissolution Rate Studies of UO2Under Both Anoxic and Reducing Conditions.
Authors: Martínez-Torrents A. , Giménez J. , Casas I. , de Pablo J.
Published: July 2014

A flow-through experimental reactor has been designed in order to perform studies at both high pressure and high temperature conditions. A chromatographic pump is used to impulse the leachant throughout the reactor in order to work at very low flows but high pressures. Therefore, high surface solid to volume leachant ratios, similar to the ones predicted in the final repository, can be obtained. The reactor allows working at different atmospheres at pressures up to 50 bars. The temperature inside the reactor can be set using a jacket.

Using this new reactor the evolution of uranium concentrations released from an UO2sample was studied at different conditions.

The results show that at hydrogen pressures between 5 and 7 bars, hydrogen peroxide does not seem to significantly oxidize the uranium (IV) oxide. Uranium concentrations in those experiments remain between 10-8mol·l-1and 10-9mol·l-1.
A Study of Natural Metamict Yttrium Niobate as Analogue of Actinide Ceramic Waste Form
Authors: Qiuxiang Cao , Isakov Anton I. , Xiaodong Liu , Krivovichev Sergey V. , Burakov Boris E.
Published: July 2014

Natural metamict mineral found as large (1-3 cm in size) homogeneous grains (as assumed, former single crystals), was investigated by X-ray powder diffraction (pXRD), high-temperature pXRD, scanning electron microscopy (SEM) and electron microprobe analysis (EMPA). The average chemical composition obtained by EMPA is (wt. %): Nb2O5 – 42.6; Ta2O5 – 4.4; TiO2 – 9.2; UO3 – 4.4; ThO2 – 1.0; MnO – 1.3; FeO – 19.4; Y2O3 – 16.6.

The untreated (original) sample is X-ray amorphous. The sample remained amorphous after annealing at 400 °C for 1 hour. The sample became almost fully crystalline after annealing at 700 °C for 1 hour with an X-ray diffraction pattern similar to that of Fe-columbite (ICCD: 01-074-7356). Further annealing at 1000 °C and higher temperatures caused changes in the phase composition of the sample. It was proposed that under self-irradiation a single-phase U-Th-bearing solid solution, based on monocrystalline Y-niobate, became metamict but remained homogeneous without evidence of solid solution destruction. However, this metamict solid solution is unstable under thermal treatment and recrystallization.
Molten Salt Synthesis of Zirconolite Polytypes
Authors: Gilbert M. R.
Published: July 2014

Zirconolite (CaZrTi2O7), a durable and compositionally flexible titanate ceramic for the immobilization of separated actinides, is currently the UK’s preferred candidate phase for the immobilization of plutonium dioxide arising from aqueous reprocessing. Here, its suitability as a waste-form for actinide chlorides arising from pyrochemical reprocessing is investigated through synthesis via a molten salt mediated reaction using a number of different salt eutectics (MgCl2:NaCl, CaCl2:NaCl and KCl:NaCl). It is found that the effectiveness of the molten salt synthesis of zirconolite is governed by the solubility of ZrO2 in the salt medium used; the synthesis proceeding via the formation of a perovskite (CaTiO3) intermediate which then reacts with ZrO2 to form zirconolite via a solution-diffusion mechanism. Most notably, in the KCl:NaCl eutectic different zirconolite polytypes are formed at different synthesis temperatures, with zirconolite-3T forming at 900 °C, giving way to zirconolite-2M at 1200 °C.
The Book of Manāqib and Prophetic History
Authors: Ahimsa-Putra Heddy Shri
Published: July 2014

In order to understand and to read the book completely with high curiosity, historians and scholars of socio-cultural studies need to be not merely critical as usually required in every discipline, but also should be widely open-minded and fully aware that history has diverse meanings in accordance with perspective used to interpret it. Why? This is because this book is an unusual book of history in usual sense of the word. Although written using historical sources or written documents about empirical events occured in the past, this book discusses the meaning of history and its sources started with doubting or questioning—indirectly—various assumptions underlying historical inquiries that so far have been conducted. This book basically is a narration or story about the Book of Manaqib that describes the legend of famous Muslim scholar (‘ulama’, sing ‘alim) who was known among the Sufis as “Prince of Saints” (sultan al-awliya’) or “pole of saints” (wali al-qutb), Shaykh ‘Abd al-Qadir al-Jilani. Among Indonesian Muslims, he is popularly known as Syekh ‘Abdul Qadir Jaelani., Of course, this book does not simply discuss the life of this legendary scholar, but also discusses the position and the significance of the Book of Manaqib of Shaykh ‘Abd al-Qadir al-Jilani. The question remains, “what are the reasons leading Dr. Ajid to discuss such a book?” We can find the answer to this question throughout this book explicitly and implicitly.

Published: July 2014

Information about the use of floristic resources of the immediate edges of ombrophilous forest (Atlantic rainforest) fragments by stingless bees is not readily available in the scientific literature. Considering the importance of these plant species for local guilds of stingless bees, this study aimed to identify and characterize the flora of the immediate borders of four Atlantic rainforest fragments situated in Baturité massif, state of Ceará, used as food resource by stingless bees. We studied the growth-form of the plants, the floristic similarity between edges and the effect of rainfall on the flowering, and suggested simple techniques for handling these areas. We compiled a total of 82 plant species with a predominance of tree and shrub form. There were different floristic richness between areas and rainfall had differentiated influence on flowering, according to the edge. We concluded that the florist components of the studied edges are relevant to the stingless bee guilds, but alternative management practices are needed to conserve both plant and bee species.
Pull test performance and correlation with falls risk in Parkinson?s disease
Authors: Munhoz Renato P. , Teive Helio A.
Published: July 2014

Postural instability (PI) and falls are major sources of disability in Parkinson’s disease (PD). Our objectives were to evaluate the correlation between the pull-test (PT) scores and falls. Patients underwent a standardized data collection including demographic, clinical data, and the UPDRS scores for falls and the PT. Cases with scores >1 for falls were considered frequent fallers. 264 patients were included with mean age 67.6±10 years, mean age of onset 59.1±10.7 years. Comparison between PT scores versus the proportion of frequent fallers and the mean score of the UPDRS for falls showed that for each increase in the PT score, both parameters were significantly worse, with positive linear relationship. For any abnormal PT score, sensibility and negative predictive value were excellent; specificity and positive predictive value improved with worse PT scores. In conclusion, the PT provides important and reliable information regarding PI and the risk of falls in PD.

Authors: Sanges Giuseppe , Gamerra Mario , Sorrentino Gerardo , Luca Roberto De , Merone Maddalena , Feleppa Michele , Bigal Marcelo Eduardo
Published: July 2014

Objective: To measure the intra-sinus pressure and the maxillary sinus functional efficiency (MSFE) in individuals with chronic facial pain after conservative or conventional endoscopic maxillary surgery, as well as in controls. Method: Sinus manometry was performed 5 times during inhalation. Results: The resemblance of pressure values comparing those treated with minimally invasive surgery and controls was remarkable, while traditional surgery significantly decreased intrasinusal pressures. The MSFE was 100% in the three tested times for controls, close to that in those submitted to minimally invasive surgery (98.3%, 98.8%, and 98.0%) and significantly impaired after conventional surgery (48.8%, 52.1%, 48.5 %, p<0.01). All patients submitted to minimally invasive surgery remained pain-free after three months of surgery, relative to 46.7% of the submitted to conventional surgery (p<0.05). Conclusion: Minimally invasive sinus surgery is associated with functionality of the chambers that resemble what is found in normal individuals.
Mental health of children and adolescents with epilepsy: analysis of clinical and neuropsichological aspects
Authors: Moreira Fernanda de Souza , Lima Andrea Bandeira de , Fonseca Paula Christina , Maia Filho Heber de Souza
Published: July 2014

Epilepsy compromises the development of cognitive and social skills and represents a risk of psychiatric comorbidity. Objective: To compare psychopathological symptoms in children with epilepsy and in a healthy group, and to correlate the results with neuropsychological and clinical variables. Method: Forty five children with idiopathic epilepsy and sixty five healthy controls underwent neuropsychological evaluation and their caregivers replied to a psychopathology questionnaire (Child Behavior Checklist – CBCL). Results: There were significant differences in CBCL, with poorer results showed mainly by patients with epilepsy. There was no significant association between any psychopathological symptom and disease duration or amount of antiepileptic drugs used. There was positive correlation between intelligence quocient and CBCL on items such as sluggish cognitive tempo, aggressive behavior, attention problems and activities and a negative relation between academic achievement, conduct and rule-breaking behavior. Conclusion: Children with epilepsy had the worse results in the psychopathology evaluation. Certain psychopathological variables are related to the cognitive profile, with no relation to clinical variables.

Published: July 2014

The aim of this study was to identify the main health management issues in Brazil according to the opinion of managers who were intentionally chosen. Data was collected from July to November 2010, through key-informant interviews: two directors from national reference private hospitals, located in Southeast Brazil; and executive authorities of the Brazilian Unified Health System (SUS), one of each government level - municipal, state, and federal managers. SUS management was considered outdated; the system was defined as lacking stable funding and having flaws in planning and service assessment. Moreover, both sectors lack professionalization in management. In conclusion, SUS is still in consolidation and requires more resources, stable funding and management able to bring its principles and guidelines into reality. Management issues affect both public and private sectors and the public-private partnerships have not been oriented by public responsibility.

Authors: Kloh Daiana , Lima Margarete Maria de , Reibnitz Kenya Schmidt
Published: July 2014

This study focuses on the ethical and social commitment in nursing education and its impact on the development of the teaching plan, with the viewpoint that this theoretical reflection can contribute to awaken the interrelationship of the teaching plan and ethical and social commitment in college-level courses. It is assumed that the concept of ethics adapts to the values relative to each time and place, being considered an essential element for the comprehensive education of human beings. In order for education to be anchored in actions in accordance with social, ethical and professional commitment, ethical principles should permeate the curriculum content, and be present in teaching positions that involve interpersonal relationships and evaluation procedures.

Authors: Bandeira Danieli , Cogo Silvana Bastos , Hildebrandt Leila Mariza , Badke Marcio Rossato
Published: July 2014

This qualitative and descriptive study aimed to identify how nursing course professors approach death and dying in the university and what the implications are on the formation process. Ten professors of the undergraduate nursing course were intentionally selected and underwent semi-structured interviews, which were recorded. The thematic analysis of the data revealed that the presence of the fact caused insecurity in the interviewees and portrayed the lack of preparation in the undergraduate course, which could indicate a certain difficulty working with this theme. Furthermore, the interviewees highlighted the importance of working with death and dying. It is essential to understand the university to be a transforming agent of reflective subjects and a promoter of conditions for the student to experience the aspects involved in the care when faced with death.

Authors: Santos Érick Igor dos , Gomes Antonio Marcos Tosoli , Oliveira Denize Cristina de
Published: July 2014

The aim of this study was to analyze the social representations of vulnerability and empowerment of nurses, in the context of their relationships with the work environment, in which they care for people with HIV/AIDS. A qualitative and descriptive study was carried out with 30 nurses in a public hospital that is a reference for HIV/AIDS care. The theoretical framework of the procedural approach from the Social Representations Theory was adopted. The interviews were transcribed and submitted to thematic content analysis using the software Nvivo 9.0. Vulnerability was expressed as embarrassment, dissatisfaction, distress, frustration, insecurity, overload and stress. In turn, empowerment was expressed in the form of positive interpersonal relationships, moral and operational support from the team, adaptations and improvisations, acquisition of scientific knowledge, and professional self-protection.

Published: July 2014

This is a qualitative study with the aim to understand the meaning of experiencing illness for a child with cancer. The thematic drawing-story was used, with eight children aged between 6 and 12 years old, from February to May of 2012. The material was analyzed according to the theoretical and analytical framework of the French Discourse Analysis line, which seeks to understand the socio-historical processes of meaning production. The study revealed that, for the child with cancer, the disease is found out in an unexpected manner and he/she is soon inserted into a new context. In addition, the child faces barriers that may delay diagnosis, having his/her routine changed. The child presents signals and symptoms that cause discomfort and anxiety. At the same time, the child hopes to be healed with the treatment accomplishment. The results may contribute to changes in nursing care for this population.
Analysis of quality indicators of central sterile supply departments at accredited public hospitals
Authors: Fusco Suzimar de Fátima Benato , Spiri Wilza Carla
Published: July 2014

This study aimed to describe and analyze quality indicators of Central Sterile Supply Departments in Accredited Public Hospitals in São Paulo state and their management by those in charge of those departments. It is a multiple-case study, presenting interconnected data from three accredited hospitals in a report on cross-referenced cases. Data were collected by semi-structured interviews with the person in charge and by technical visits with documental analysis. Results showed the difficulty which those in charge have in identifying specific indicators for the department; the indicators mentioned relate to production and client satisfaction surveys, and do not describe the effective quality of the service, as they are fragmented and do not consolidate results in the search for improvement. This suggests low specificity and low sensitivity of the National Accreditation Organization criteria to this department's context.
Reasons which lead the health services not to allow the presence of the birth companion: nurses' discourses
Authors: Brüggemann Odaléa Maria , Ebsen Erika Simas , Oliveira Maria Emilia de , Gorayeb Marina Kuchiniski , Ebele Romana Raquel
Published: July 2014

This qualitative research aimed to investigate the reasons the health services of Santa Catarina, Brazil, do not allow the presence of the birth partner of choice of women in the birthing process. The data were collected from September 2011 to January 2012 through semi-structured interviews with 12 nurses responsible for obstetric centers which did not permit, or permitted sometimes, the presence of the birth companion. The interviews were analyzed using the Discourse of the Collective Subject, in which three themes emerged: professionals' resistance to the presence of the companion; lack of physical infrastructure and human and material resources; and the institution's resistance to implementing the Companion's Law. The discourses show that impeding the presence of the companion is mainly related to the decision of the professionals and the inadequacy of the organizational structure. This requires changes in the attitude of the staff, institutional support, and management strategies to increase the support for the presence of the woman's companion of choice.
Oportunidades de aprendizaje y competencias matemáticas: un estudio de dos casos
Authors: Carrillo José , Contreras Luís C. , Zakaryan Diana
Published: July 2014

Este estudio trata de conocer la importancia que tienen las oportunidades de aprendizaje (OTL) que ofrece el profesor en su aula a la hora de facilitar la adquisición de las competencias matemáticas de sus estudiantes (CM). Se presenta la parte empírica de una investigación, que ha consistido en el estudio de dos casos particulares (en España y Armenia), y documentamos los resultados obtenidos a la luz de un modelo teórico OTL-CM, construido de forma emergente en el proceso de análisis de los datos. Los resultados de nuestra investigación han constatado que las escasas OTL que promueven el aprendizaje significativo de las matemáticas limitan tanto la adquisición de los conocimientos y destrezas matemáticas básicas, como la capacidad de aplicarlos en situaciones de la vida real.

Conocimiento matemático de futuros profesores para la enseñanza de la probabilidad desde el enfoque frecuencial
Authors: Gómez Emilse , Batanero Carmen , Contreras José Miguel
Published: July 2014

En este trabajo se evalúan algunos componentes del conocimiento matemático para la enseñanza de la probabilidad (desde el enfoque frecuencial) de futuros profesores de Educación Primaria. Para evaluar el conocimiento común del contenido se analizan las soluciones dadas individuamente por 157 futuros profesores españoles de Educación Primaria a un problema abierto. Una vez discutidas con los participantes sus soluciones al problema, se analizan dos componentes del conocimiento didáctico, en 81 de estos profesores, trabajando en pequeños grupos: (a) para evaluar el conocimiento especializado del contenido se pide a los participantes identificar los contenidos matemáticos en la tarea; (b) evaluar el conocimiento del contenido y los estudiantes se les pide identificar y justificar, entre un grupo de respuestas dadas por alumnos de Educación Primaria, cuáles son correctas e incorrectas. Mientras que en la evaluación inicial se observaron diversas concepciones erróneas, como sesgo de equiprobabilidad, heurística de representatividad y subestimación de la variabilidad en el muestre, en la segunda los futuros profesores son capaces de identificar las respuestas correctas e incorrectas, explicando la razón de los errores. Aunque el conocimiento didáctico es aún insuficiente, pues se identifican pocos objetos matemáticos en la tarea, se deduce la utilidad de la actividad para el desarrollo del conocimiento de los futuros profesores.
Gestión didáctica en clases y su relación con las decisiones del profesor: el caso del teorema de pitágoras en séptimo grado
Authors: Olfos Raimundo , Guzmán Ismenia , Estrella Soledad
Published: July 2014

Este artículo presenta el análisis de la gestión didáctica de dos profesoras de matemáticas en Chile, a partir de la observación directa de sus clases de geometría del teorema de Pitágoras, en el grado 7 y alumnos de 12 a 13 años. El objetivo del estudio consiste en detectar, en la gestión de la clase, los índices de las decisiones didácticas que toman las docentes sobre el tema, y verificar si sus gestiones siguen algún modelo didáctico de la acción pedagógica. Este estudio se centra en el análisis de episodios seleccionados de las clases, el cual se inscribe en una perspectiva constructivista del aprendizaje y de la enseñanza de la matemática, basado en ideas claves de la teoría de situaciones didácticas de Brousseau. La gestión de los profesores conduce a un modelo de transmisión de conocimientos que dificultan el desarrollo de las matemáticas y el protagonismo del estudiante.
Análisis según el modelo cognitivo APOS* del aprendizaje construido del concepto de la derivada
Authors: Urquieta M. Angélica Vega , Yañez José Carrillo , Andrade Jorge Soto
Published: July 2014

Este trabajo fue motivado por el bajo rendimiento de los estudiantes que ingresan a primer ciclo en la educación superior en Chile. Por lo tanto, nuestro interés fue investigar cómo aprenden matemáticas los estudiantes, cómo construyen conocimiento y cuál es el nivel de aprendizaje construido en un tema, de especial dificultad para ellos, como es el concepto de la derivada y sus aplicaciones. Este trabajo es parte de una investigación más extensa que consideró un estudio de casos múltiples. Presentamos, aquí, los resultados obtenidos de dos de ellos. Para indagar el aprendizaje construido se usó el modelo cognitivo APOS de Ed Dubinsky. Se creó un entorno interactivo de enseñanza para el aula apoyado por Módulos de Clases y clases de trabajo práctico basado en Talleres Computacionales. Se mencionarán algunos resultados brevemente. Se descubrió que, si el concepto de derivada en un punto no es comprendido a nivel de Acción, los estudiantes tienen dificultades para extenderlo y transitar a un nivel superior de comprensión e interpretar el concepto geométricamente. Además, tienen dificultades de comprensión cuando deben discriminar entre proposiciones falsas y verdaderas enunciadas sobre propiedades de la derivada relacionadas con la monotonía y la concavidad de una función. Se obtuvieron conclusiones sobre el aprendizaje evidenciado y sobre la estrategia de enseñanza implementada.
The square as a figural concept
Authors: Vodušek Helena Bezgovšek , Lipovec Alenka
Published: July 2014

In the geometry research we operate with mental entities, which contain an image as an essential component. This helps us in thinking, but it often does not coincide with the formal definition. In many cases, flat shapes are represented only with a curve, a boundary, and not as a part of the plane, which can lead to a false conception of flat shapes. The purpose of the research was to clarify pre-service elementary teachers' (N=186) concept image in the case of a square, whether it is hollow or filled, and what role it plays in problem solving. Qualitative methodology, specifically thematic analysis, was used in order to analyze participants' responses to a specially designed task. Only a very small part of participants gave expected answers. The results showed that the pre- service teachers' image of a square as a frame totally dominated the conceptual part of the figural concept of a square.

Context Liver cirrhosis patients with hepatocellular carcinoma present nutritional alterations and metabolic disorders that negatively impact the prognosis. Objective The objective is to identify alterations in the metabolism of macro and micronutrients among liver cirrhosis patients with and without hepatocellular carcinoma and their relation to the Child-Turcote-Pugh score and Barcelona Clinic Liver Cancer staging. Methods Analytical transversal study, with 31 hepatocellular carcinoma patients and 48 liver cirrhosis patients. Laboratorial exams were carried out. The existence of an association between the biochemical parameters and the disease severity as well as the presence of hepatocellular carcinoma was assessed. Results The metabolic-nutritional profile of liver cirrhosis patients caused by the hepatitis C virus and hepatocellular carcinoma showed alterations, specifically the lipid (total cholesterol, HDL and triglycerides), protein (albumin, creatinine and uric acid), iron (transferrin, iron and ferritin saturation), hematocrit and hemoglobin, zinc and B12 vitamin profiles. There is a relation between nutritional biochemical markers and the Child-Turcote-Pugh, as well as Barcelona Clinic Liver Cancer staging. Conclusions Considering the existence of alterations in the metabolism of nutrients in liver cirrhosis patients with and without hepatocellular carcinoma, and also that conventional nutritional assessment methods present limitations for this population, the biochemical laboratorial exams are valid to complement the diagnosis of the nutritional state in a quick and practical manner.

Context There is a relative lack of studies about exhaled nitrite (NO2-) concentrations in cirrhotic and transplanted patients. Objective Verify possible differences and correlations between the levels of NO2-, measured in plasma and exhaled breath condensate collected from patients with cirrhosis and liver transplant. Method Sixty adult male patients, aged between 27 and 67 years, were subdivided into three groups: a control group comprised of 15 healthy volunteers, a cirrhosis group composed of 15 volunteers, and a transplant group comprised of 30 volunteers. The NO2- concentrations were measured by chemiluminescence. Results 1) The analysis of plasma NO2- held among the three groups showed no statistical significance. 2) The comparison between cirrhotic and control groups, control and transplanted and cirrhotic and transplanted was not statistically significant. 3) The measurements performed on of NO2- exhaled breath condensate among the three groups showed no statistical difference. 4) When comparing the control group samples and cirrhotic, control and transplanted and cirrhotic and transplanted, there was no significant changes in the concentrations of NO2-. Conclusion No correlations were found between plasma and exhaled NO2-, suggesting that the exhaled NO2- is more reflective of local respiratory NO release than the systemic circulation.

Context Hypertension is a common disorder in general practice and has a widely known association with type 2 diabetes mellitus. Low adhesion to clinical treatment may lead to poor results. Obesity surgery can bring early and relevant resolution rates of both morbidities. Objective To describe hypertension evolution after Roux-en-Y gastric bypass in patients with type 2 diabetes mellitus. Method Descriptive observational study designed as a historical cohort of 90 subjects with hypertension and diabetes who underwent Roux-en-Y gastric bypass and were evaluated before and after surgery. Results It was observed a hypertension resolution rate of 85.6% along with markedly decrease in anti-hypertensive usage. Mean resolution time was 3.2 months. Resolution was associated with homeostasis model assessment – insulin resistance, preoperative fasting insulin, anti-hypertensive usage, hypertension time, body mass index and percentage of weight loss. Resolution of hypertension was not statistically associated with diabetes remission within this sample. Conclusion Roux-en-Y gastric bypass was a safe and effective therapeutic tool to achieve hypertension resolution in patients who also had diabetes mellitus.

Context Adalimumab is a fully-human antibody that inhibits TNF alpha, with a significant efficacy for long-term maintenance of remission. Studies with this agent in Latin American Crohn’s disease patients are scarce. Objectives The objective of this study was to outline clinical remission rates after 12 months of adalimumab therapy for Crohn’s disease patients. Methods Retrospective, single-center, observational study of a Brazilian case series of Crohn’s disease patients under adalimumab therapy. Variables analyzed: demographic data, Montreal classification, concomitant medication, remission rates after 1, 4, 6 and 12 months. Remission was defined as Harvey-Bradshaw Index ≤4, and non-responder-imputation and last-observation-carried-forward analysis were used. The influence of infliximab on remission rates was analyzed by Fischer and Chi-square tests (P<0.05). Results Fifty patients, with median age of 35 years at therapy initiation, were included. Remission rates after 12 months of therapy were 54% under non-responder-imputation and 88% under last-observation-carried-forward analysis. After 12 months, remission on patients with previous infliximab occurred in 69.23% as compared to 94.59% in infliximab-naïve patients (P = 0.033). Conclusions Adalimumab was effective in maintaining clinical remission after 12 months of therapy, with an adequate safety profile, and was also more effective in infliximab naïve patients.

Context Ulcer is the most common gastrointestinal disturbance resulting from an inadequate gastric mucosal defense. Several drugs are available in the market to address the disease; however, these drugs are associated with unnecessary side effects. Objectives Previous research have confirmed the efficacy of plant extracts for possible treatment of the disease. This research aims to evaluate the anti-ulcer properties of medicinal plants. Methods Methanol extracts from the leaves of Intsia bijuga, Cynometra ramiflora, Tamarindus indica, Cassia javanica, Cassia fistula, Bauhini purpurea, Senna spectabilis, Senna siamea and Saraca thaipingensis were evaluated for their anti-ulcer activity using HCl-ethanol as ulcerogen. Results All extracts showed inhibitory activity with I. bijuga, T. indica, S. spectabilis and S. thaipingensis exhibiting more than 50% inhibition. S. thaipingensis showed the highest activity at 80%. S. spectabilis and S. thaipingensis were partitioned further into hexane, ethyl acetate and aqueous fractions. The aqueous and ethyl acetate fractions of S. spectabilis showed significant increased in its activity while the hexane and ethyl acetate fractions of S. thaipingensis gave higher activity than its aqueous portions. Conclusions We conclude that plant extracts are potential sources of new anti-ulcer agents.
Portfolio valuation in banks

Published: July 2014

Frequent references are made to the use of portfolio spread rates in managing financial risks in banks, but indications as to the procedures for determining such rates are very scant.The purpose of this article is to present some initial ideas on the subject: a Standard Funding system indicates what each portfolio should have earned, while an Actual Funding system points out what each portfolio did, in fact, earn; additionally, by comparing the outcomes of the two funding systems for each portfolio, it is possible to determine what each portfolio earned (or lost) in the way of arbitrage.
Indústria de tabaco e cidadania: confronto entre redes organizacionais
Authors: Boeira Sérgio Luís
Published: July 2014

O artigo aborda a história da indústria de tabaco no Brasil e da formação de sua rede estratégica, bem como da rede dos atores sociais que a contrapõem. Na primeira parte, apresenta-se uma correlação entre a história da produção industrial, do consumo de tabaco e do antitabagismo. Na segunda parte são apresentados os conceitos de rede estratégica e de rede multifragmentária (antifumo), propostos para facilitar a compreensão de alguns dos múltiplos aspectos conflitivos entre as duas redes. A pesquisa de campo envolveu entrevistas com empresários, fumicultores, sindicalistas, técnicos de empresas fumageiras, técnicos do setor saúde, líderes de ONGs e outros atores sociais. Os resultados sugerem que há um crescimento simultâneo e contraditório das redes, com larga vantagem para a rede estratégica das empresas de tabaco, e um conjunto de dilemas no interior da rede multifragmentária.
