A estrutura dos compostos orgânicos em livros didáticos de nível superior: análise sob a perspectiva de Bachelard
Authors: Cedran Jaime da Costa , Santin Filho Ourides 
Published: October 2019

O presente trabalho tem por objetivo analisar a sequência apresentada por alguns livros didáticos de química orgânica, ao abordar as estruturas carbônicas e seu arranjo espacial, e discuti-las sob a ótica da epistemologia de Gaston Bachelard. Os livros foram escolhidos por serem adotados nas disciplinas introdutórias de Química Orgânica em algumas das principais universidades brasileiras. Os resultados mostram que todos os livros se iniciam com a mesma abordagem o tema de estrutura e propriedades dos compostos orgânicos, partindo das características eletrônicas do átomo de carbono e das possibilidades de sua hibridação, para depois apresentarem conceitos mais simples, obtidos a partir de dados experimentais. Tal abordagem caracteriza uma inversão do ponto de vista histórico e também do ponto de vista epistemológico, tomando como referencial a sequência de escolas filosóficas propostas por Bachelard. Palavras-chave: Química Orgânica. Análise de Livros Didáticos. Bachelard.

Este texto apresenta reflexões da Comissão Assessora de Área de Pedagogia do Enade 2014 acerca da relação entre os conteúdos constantes nas questões do Enade/Pedagogia em 2008, 2011 e 2014 e as Diretrizes Curriculares Nacionais para o Curso de Graduação em Pedagogia/2006. Traz um breve histórico do curso de Pedagogia no Brasil, evidencia as diretrizes de formação do pedagogo, expõe a pesquisa documental como metodologia, a qual utilizou o software Alceste para tratar os dados, cuja análise será exibida na sequência. Constatou-se que essas provas do Enade trazem elementos que revelam a existência de convergência entre a orientação da formação e a avaliação do curso, porém, devido ao contexto amplo de avaliação de política de formação, não é possível verificar, plenamente, todos os elementos constitutivos dessa formação.

Avaliação externa: conceitos, significados e tensões
Authors: Lélis Luziane Said Cometti , Hora Dinair Leal da 
Published: October 2019

O estudo discute a relação existente entre a avaliação externa e a prática pedagógica, as compreensões adquiridas pelos profissionais que atuam no ambiente escolar, as apropriações dos resultados, as tensões e as estratégias utilizadas para a melhoria do ensino. As significações construídas a respeito da avaliação externa são provenientes de revisão bibliográfica e pesquisa de campo realizada em uma escola pública municipal de Belém/PA. As análises acerca dos resultados indicam dois movimentos/posicionamentos concomitantes: o dos gestores pedagógicos, que não privilegiam os resultados dos testes externos e nem o índice de qualidade nacional na realização da organização do trabalho pedagógico; e o dos professores que estão modificando “naturalmente” seus fazeres em busca de resultados preconizados pelo Índice de Desenvolvimento da Educação Básica (IDEB). Palavras-chave: Avaliação externa. Prática pedagógica. Regulação. Responsabilização.
Modelagem matemática e letramento científico no ensino de física
Authors: Souza Ednilson Sergio Ramalho de , Santo Adilson Oliveira do Espírito 
Published: October 2019

Na atual sociedade tecnológica e globalizada, permeada de rápidas transformações socioculturais, os conteúdos para o ensino de física não podem mais se concentrar na aprendizagem conceitual. Além de conceitos, os estudantes precisam construir competências que os possibilitem investigar e tomar decisões críticas cientificamente fundamentadas, ou seja, é necessário letramento científico. Competências desse tipo envolvem a adoção de uma abordagem educacional ativa, tal como a modelagem matemática. O objetivo deste artigo é analisar a modelagem como geradora de competências essenciais para a formação de sujeitos letrados cientificamente no contexto amazônico do ensino de física. A pesquisa de campo envolveu três ciclos de modelagem com professores de ciências (n=13) do município de Almeirim, Pará, Brasil. Os métodos para produção de dados foram inspirados na metodologia mista. A interpretação de informações recorreu a procedimentos da análise textual discursiva em três fases: unitarização, categorização e metatexto. Os resultados evidenciam que a modelagem matemática pode ter implicações positivas para o letramento científico em física, especialmente para desenvolver competências para diferenciar questões com possibilidades de serem investigadas cientificamente, para avaliar formas de explorar cientificamente dada questão e para usar diferentes linguagens visando a manifestar aprendizagens.

Gobernanza Intercultural y Ciudadanía Política en Pátzcuaro, Michoacán, México
Authors: Ibarra Miguel Rodrigo González 
Published: October 2019

El tema de ciudadanía advierte un análisis desde diversas interpretaciones teóricas y metodológicas que apuntan hacia una perspectiva pluridimensional y connotaciones complejas. No obstante, existe un cierto consenso respecto a que el término ciudadanía remite a la pertenencia de los individuos y los grupos sociales a una determinada comunidad política. Este trabajo se propone analizar: a) cuál es la importancia de la ciudadanía y la gobernanza intercultural en los procesos de gobierno y construcción de políticas públicas locales; b) explicar de qué forma se concibe la construcción de ciudadanía activa a través de la llamada participación solidaria; y c) analizar cuáles fueron las aportaciones del Consejo Ciudadano de la Región Lacustre de Pátzcuaro en el Estado de Michoacán, México, hacia la construcción de ciudadanía política y gobernanza intercultural. Utilizando una perspectiva cualitativa -a través de la revisión de documentos, entrevistas en actores y análisis empírico- se discute que, en mayor o menor medida, la creación del Consejo motivó la gobernanza intercultural que requieren las comunidades para incidir en los procesos de participación solidaria y construyó las bases para una ciudadanía activa y solidaria hacia temas relacionados con la educación y el medio ambiente, entre otros temas, comunitarios. Palabras claves: Gobernanza Intercultural. Ciudadanía. Michoacán. Consejo Ciudadano de la Región Lacustre.
Shrinking municipalities and their budgetary revenues on the example of the Warmian-Masurian Voivodeship in Poland
Authors: Wichowska Anna 
Published: October 2019

Research background: Adverse demographic changes in many local administration units around the world lead to their shrinkage. These processes are usually accompanied by economic changes. The economic consequences of shrinkage can be assessed based on the budgetary revenues of local units, which are largely dependent on the local population and the demographic structure.
Purpose of the article: The aim of this article is to evaluate the shrinkage of Polish municipalities and the effects of population change on the budgetary revenues of local administration units. The analysis was conducted in selected municipalities of the Warmian-Masurian voivodeship, which is the least economically developed region in Poland. The analysis covered the period between 2012 and 2017.
Methods: The shrinkage of municipalities was evaluated with the use of the methods proposed by the Shrinking Cities International Research Network (SCIRN). According to this methodology, a local unit shrinks when the annual decrease in population exceeds 0.15% for more than five consecutive years. The influence of demographic changes on the budgetary revenues of municipalities was evaluated with the use of linear correlation analysis (Pearson's r) as well as a survey conducted among municipal treasurers in the Warmian-Masurian voivodeship.
Findings & Value added: Symptoms of shrinkage were described in selected municipalities of the Warmian-Masurian voivodeship. The presence of correlations between different categories of budgetary revenues and demographic changes was confirmed. The results of the study and the formulated practical recommendations constitute constructive inputs to the discussion on possible solutions to the analyzed problem. They can also be used in further research to analyze other aspects of municipal budgets (the consequences of depopulation for budgetary expenditures, municipal debt, etc.) or conduct comparisons with other regions in Poland and in the world.
Becoming business-like: the determinants of NGOs? marketization turning into social enterprises in Poland
Authors: Mikołajczak Paweł 
Published: October 2019

Research background: NGOs face an increasing expectation to be more business-like. They are becoming involved in selling services by performing a commercial activity, which, in turn, is a basic condition for creating social enterprises. The changes related to this approach are an essential condition for their survival and a significant reason for developing their new form as social enterprises. On the other hand, there is no lack of critical opinions related primarily to mission volatility. Currently, a discussion is taking place in the literature on factors that may affect NGOs? marketization; these, however, have not been empirically verified yet. The identified research gap constituted a major challenge for the author.
Purpose of the article: The purpose of this paper is to verify whether conducting a business activity influences the entrepreneurial way of NGOs? operation, and to indicate the factors that have a significant impact on their marketization.
Methods: On the basis of a representative national survey of 3,800 NGOs, including 412 social enterprises in Poland. a one-factor analysis of variance (ANOVA) and a stepwise backward regression analysis were carried out.
Findings & Value added: The analysis of the results confirms that there are significant differences between NGOs operating as social enterprises and NGOs not performing a business activity. In contrast with the existing literature, this study indicates that social enterprises have less diversified revenue sources and use a more or less democratic governance model. Moreover, Polish social enterprises less frequently adjust their policy direction to donors? interests. The factors significantly affecting NGOs? marketization include action strategies for several years, activity in favor of external benefit takers, close business cooperation, lack of permanent financing sources, and regular activity combined with flexible working time.

Limfadenopatia u dzieci i dorosłych: zasady postępowania diagnostycznego
Authors: Styczyński Jan 
Published: September 2019

StreszczeniePowiększenie węzłów chłonnych (limfadenopatia) jest jednym z najczęstszych objawów klinicznych, zwłaszcza u dzieci. U ok. 50% zdrowych dzieci dochodzi do powiększenia węzłów chłonnych; najczęściej w wieku 2-10 lat. Celem pracy jest przedstawienie zasad postępowania diagnostycznego u pacjenta z limfadenopatią, jak również omówienie jej przyczyn, zasad rozpoznawania oraz przedstawienie rekomendacji postępowania klinicznego u pacjenta z powiększeniem węzłów chłonnych. Etiologię limfadenopatii u dzieci i dorosłych oraz związane z tym ukierunkowanie diagnostyki różnicowej można określić wg kilku reguł przedstawionych akronimami w języku angielskim: MIAMI, CHICAGO, wg liter alfabetu lub lokalizacji. W postępowaniu diagnostycznym obowiązuje czteroetapowy proces: (1) badanie podmiotowe (wywiad) i przedmiotowe; na tym etapie najczęściej zapada decyzja o hospitalizacji; (2) badania laboratoryjne; (3) badania obrazowe: USG i/lub tomografia komputerowa; (4) otwarta biopsja węzła. W chwili obecnej otwarta biopsja węzła i badanie histopatologiczne są złotym standardem diagnostycznym limfadenopatii u dzieci. Ze względu na ryzyko maskowania lub opóźnienia rozpoznania chłoniaka lub białaczki do czasu ustalenia jednoznacznej diagnozy nie należy podawać steroidów. U dzieci z ostrym jednostronnym powiększeniem przednich węzłów chłonnych szyjnych oraz z objawami ogólnymi powinna zostać zastosowana antybiotykoterapia empiryczna.
Znaczenie techniki aCGH w nowotworach mieloproliferacyjnych – przegląd literatury
Authors: Osmańska Katarzyna , Pilarska-Deltow Maria , Haus Olga 
Published: September 2019

StreszczenieNowotwory mieloproliferacyjne (MPN) są klonalnymi chorobami komórek macierzystych szpiku, które charakteryzują się proliferacją jednej lub więcej linii mieloidalnych krwiotworzenia: granulocytowej, czerwonokrwinkowej i/lub megakariocytowej. Do MPN BCR-ABL1(-) zalicza się m.in. czerwienicę prawdziwą (PV), nadpłytkowość samoistną (ET) oraz pierwotną mielofibrozę (PMF). Nowotwory mieloproliferacyjne BCR-ABL1(-) należą do najmniej poznanych nowotworów układu krwiotwórczego pod względem nabytych zmian genetycznych. Badania nad MPN trwają od ponad 60 lat. Podobieństwo objawów klinicznych wskazuje na wspólną patogenezę PV, ET i PMF. Głównym celem prowadzonych badań jest wytypowanie markerów, które nie tylko pomogą w diagnostyce poszczególnych typów MPN czy w klasyfikacji chorych do grup ryzyka, ale mogłyby być także celem terapeutycznym. Głównym celem terapii jest przedłużenie życia pacjentów, w tym także zminimalizowanie prawdopodobieństwa transformacji w ostrą białaczkę. aCGH jest niewątpliwie techniką bardzo przydatną klinicznie, która, choć nie znalazła jeszcze rutynowego zastosowania w klinice hematoonkologii, to wykorzystywana jest w coraz większej liczbie badań, zwłaszcza do analizy nowotworów, w których istotne są aberracje niezrównoważone. Niniejsza praca przedstawia zastosowanie techniki aCGH w nowotworach mieloproliferacyjnych.
Strategie doboru krwinek czerwonych dla biorców w różnych sytuacjach klinicznych
Authors: Fabijańska-Mitek Jadwiga 
Published: September 2019

StreszczeniePrzed transfuzją krwinek czerwonych wykonuje się rutynowe testy immunohematologiczne, dzięki którym przetacza się biorcom serologicznie zgodną krew dawców. Wyzwaniem dla serologów jest dobór koncentratu krwinek czerwonych (KKCz), gdy uodpornieni biorcy mają alloprzeciwciała z powodu wcześniejszych transfuzji lub ciąż albo wytworzą autoprzeciwciała w niedokrwistościach autoimmunohemolitycznych (NAIH). Wyzwaniem dla klinicystów jest pilna, ratująca życie transfuzja bez próby zgodności. Są to przetoczenia nagłe (krwawienie) oraz sytuacje, gdy brak jest krwi o wyjątkowych fenotypach. Ważne jest tworzenie narodowych rejestrów rzadkich dawców krwinek czerwonych i uczestnictwo w rejestrze międzynarodowym oraz przekazywanie informacji o skutkach niezgodnego przetoczenia i leczeniu ograniczającym hemolizę. Inne problemy dotyczą szczególnych grup biorców krwi, czyli: płodów, noworodków, niemowląt i pozostałych dzieci. Różnią się one cechami hematologicznymi i immunologicznymi, więc testy zgodności muszą się też różnić. Skomplikowane są transfuzje po transplantacjach komórek krwiotwórczych i narządów, gdy z powodu immunologicznego chimeryzmu dochodzi do hemolizy. Ścisła współpraca między klinicystami i immunohematologami jest konieczna, by zapewnić bezpieczeństwo transfuzji w wymienionych sytuacjach klinicznych opisanych w prezentowanej publikacji.
ABC of viral infections in hematology: focus on herpesviruses
Authors: Styczyński Jan 
Published: September 2019

AbstractViruses are a form of life that possess genes but do not have a cellular structure. Viruses do not have their own metabolism, and they require a host cell to make new products; therefore, they cannot naturally reproduce outside a host cell. The objective of this paper is to present the basic practical clinical roles of viruses in patients with hematological diseases including malignancies and non-malignan- cies, as well as those undergoing hematopoietic cell transplantation (HCT), with the focus on herpesviruses causing latent infections in severely immunocompromised patients. From the hematologist point of view, viruses can play a major role in four conditions: causing infections; causing lymphoproliferations and/or malignancies; causing (pan)cytopenia; and used as vectors in treatment (e.g., gene therapy, CAR-T cells). Taking into account the role of viruses in hematology, infection is the most frequent condition. Among DNA viruses, the highest morbidity potential for human is expressed by Herpesviridiae (herpesviruses), Adenoviridae (adenovirus; ADV), Polyomavirus (BKV, JCV), and Bocavirus. RNA viruses can play a role in pathogenesis of different clinical conditions and diseases: lymphoproliferative disorders and malignancy, possibly causing NHL, AML, MDS, and others (HCV, HIV, and others); pancytopenia and aplastic anemia (HIV, HCV, Dengue virus); respiratory infections (community-acquired respiratory virus infections; CARV) caused by Orthomyxoviruses (e.g. influenza A/B), Paramyxoviruses (e.g. human parainfluenza virus PIV-1, -2, -3, and -4; respiratory syncytial virus RSV-A and -B), picornaviruses (e.g., human rhinovirus), coronaviruses (e.g., human coronavirus), Pneumoviridiae (e.g., human metapneumovirus), and potentially other viruses.

Published: October 2019

Abstract
Extracting useful information from astronomical observations represents one of the most challenging tasks of data exploration. This is largely due to the volume of the data acquired using advanced observational tools. While other challenges typical for the class of big data problems (like data variety) are also present, the size of datasets represents the most significant obstacle in visualization and subsequent analysis. This paper studies an efficient data condensation algorithm aimed at providing its compact representation. It is based on fast nearest neighbor calculation using tree structures and parallel processing. In addition to that, the possibility of using approximate identification of neighbors, to even further improve the algorithm time performance, is also evaluated. The properties of the proposed approach, both in terms of performance and condensation quality, are experimentally assessed on astronomical datasets related to the GAIA mission. It is concluded that the introduced technique might serve as a scalable method of alleviating the problem of the dataset size.

Abstract
The aim of this study was to evaluate ovarian activity and the size of oocytes in ovarian follicles in sexually mature Landrace-Yorkshire gilts in relation to the individual seasons of the year. The study was carried out on 240 gilts slaughtered at an abattoir during the four yearly seasons. The size and weight of the ovaries, the number of follicles and corpora lutea (CL) according to individual size categories were evaluated. The oocytes were aspirated from follicles and their sizes were measured. Our evaluation of the size of the ovaries showed that they were the largest in autumn, when their mean length reached 25.8 ± 3.4 mm, while in winter their mean length was 24.2 ± 2.9 mm. The smallest weight of the ovaries was determined in autumn (mean 5.7 ± 1.4 g) and the highest in spring (mean 6.2 ± 2.2 g). The largest number of follicles in the ovaries of the gilts was recorded during the autumn months, with a predominance of follicles up to 3 mm (mean number 17.9 ± 7.5). The largest number of corpora lutea was observed in spring (mean number 12.1 ± 2.6) and the smallest in winter (mean number 6.1 ± 1.1). The oocytes from follicles of up to 3 mm size, were the smallest in spring (mean size 16.99 × 103 ± 3.42 × 103 µm2) and the largest in winter (mean size 18.90 × 103 ± 2.99 × 103 µm2). In total, the largest oocytes were aspirated from 4—6 mm follicles in autumn (mean size 19.60 × 103 ± 5.37 × 103 ± µm2). The values recorded indicated that the seasons affected the ovarian activity and the growth of oocytes in gilts.
