Maternal and Infant Care Beliefs and Practices of Aeta Mothers in Central Luzon, Philippines
Authors: Leabres Jr. Juanito , Jose Marlon , Nuqui Alvin , Nogoy Jessie , Pudadera Rene , Ramos Wilfredo
Published: February 2020

Background: This study attempts at understanding the Aetas concept of maternal and infant care, specifically, beliefs and practices of Aeta mothers during pregnancy, childbirth and care of the infant.

Methodology: Qualitative descriptive design was utilized in this research. Forty Aeta mothers were informants of this study selected via purposive sampling. Participant observation, formal and informal interviews and examination of relevant documents were the instruments for data collection.

Findings: Most respondents were between 16-27 years old, from the province of Zambales, with two pregnancies and one living child. The majority had home deliveries attended by traditional birth attendants or next of kin and had visits to the Rural Health Units for a prenatal check-up. It was found that most Aeta mothers usually visit the Rural Health Unit in their second trimester. The mothers also rely on traditional beliefs and practices passed on from elders of the community particularly on diet, hygiene, and faith in God, preparation prior to delivery, cord care and use of placenta.

Conclusion: The findings showed that the majority of the Aeta mothers interviewed adhered to some form of belief and practice that were passed to them by their elders.

Implication: Stakeholders such as government and non-government organizations should pursue promoting and enriching beliefs and practices of the Aeta and reinforcing programs with an emphasis on indigenous minorities to follow safe delivery and motherhood practices that are culturally acceptable.

Responsibility: to the problem of the category conceptualization
Authors: DZIOBAN O. , RUBAN O.
Published: February 2020

In the article the phenomenon of responsibility is considered as a socio-historical phenomenon that appears as a result of the emergence and development of social relations and as a characteristic of relations between the individual, social group and society as a whole. The key conceptual approaches to the understanding of responsibility in the history of the development of philosophical culture are analyzed. It is concluded that a major trend in information society is ubiquitous abdication of responsibility at virtually every level of its manifestation, which allows to talk about the asymmetry of society development : the extremely high degree of technological development is accompanied by the degradation of ethics and morality. This becomes theprimary contradiction, that generates social conflicts, from interpersonal to international.
Human and citizen rights and freedoms: conceptual approaches to differentiation in Germany and Ukraine
Authors: CОSІLОVА О. , FЕDІRCО I.
Published: February 2020

The article analyzes the relationship between human rights and rights of citizens in general and in Ukraine and Germany particular. Basic approaches to the classification of human rights are explored. It is emphasized that, unlike human rights, which apply to all persons without restriction, the rights of the citizen cover the sphere of legal relations of the individual with the state, characterized by the presence of citizenship. It is emphasized that in Germany the freedoms are part of the rights of individuals and are defined as “rights to liberties”, while having a negative status, which implies minimization of state influence and interference. The legal status of foreigners in both countries and the peculiarities of the exercise of their rights and freedoms are analyzed.
TWO-STAGE PRIORITIZATION PROCEDURE FOR MULTIPLICATIVE AHP-GROUP DECISION MAKING
Authors: Lin Changsheng , Kou Gang , Peng Yi , Alsaadi Fawaz E.
Published: February 2020

In this paper, we propose two-stage prioritization procedure (TSPP) for multiplicative Analytic Hierarchy Process-group decision making (AHP-GDM), which involves determining the group priority vector based on the individual pair-wise comparison matrices (PCMs), simultaneously considering the consensus and consistency of the individual PCMs. The first stage of the TSPP involves checking and revising the individual PCMs for reaching the acceptable consensus and consistency. The second stage of the TSPP involves estimating the group priority vector using Bayesian approach. The main characteristics of the proposed TSPP are as follows: 1) It makes full use of the prior information as well as the sample information during the Bayesian revision of the individual PCMs and the Bayesian estimation of the group priority vector; 2) It ensures that the revised individual PCMs reach the acceptable consensus and consistency; 3) It enriches the aggregation methods for the collective preference in multiplicative AHP-GDM. Finally, two numerical examples are used to evaluate the applicability and effectiveness of the proposed TSPP by the comparisons with several other methods.
Laminar Flame Speeds in Degenerate Oxygen–Neon Mixtures
Authors: Schwab Josiah , Farmer R. , Timmes F. X.
Published: February 2020

The collapse of degenerate oxygen–neon cores (i.e., electron-capture supernovae or accretion-induced collapse) proceeds through a phase in which a deflagration wave (“flame”) forms at or near the center and propagates through the star. In models, the assumed speed of this flame influences whether this process leads to an explosion or to the formation of a neutron star. We calculate the laminar flame speeds in degenerate oxygen–neon mixtures with compositions motivated by detailed stellar evolution models. These mixtures include trace amounts of carbon and have a lower electron fraction than those considered in previous work. We find that trace carbon has little effect on the flame speeds, but that material with electron fraction

has laminar flame speeds that are

times faster than those at

. We provide tabulated flame speeds and a corresponding fitting function so that the impact of this difference can be assessed via full star hydrodynamical simulations of the collapse process.
Distance Education for Graduate Nursing: One State School's Experience
Authors: Ostrow Lynne , DiMaria-Ghalili Rose Ann
Published: February 2020

This article describes the authors experience in teaching graduate nursing courses to students in the rural state of West Virginia during the past 20 years. The strengths and weaknesses of each technological method are detailed, from both the instructor and student perspectives. The most recently implemented system (fall 2003), Webcasting, is also described. The support required within the institution, particularly from Instructional Design and Information Systems staff, and throughout the state is reviewed. The lessons learned from one school's long history with distance education are analyzed from the theoretical perspectives of adult learners and virtual students. We share our experiences with other nurse educators so they can devote more effort to the curricular aspects of their courses, rather than reinventing the technological wheel.

The meanings of various verbal and nonverbal behaviors of Asian students are examined to clarify their communication patterns. Culture-based assumptions are identified, and measures to improve intercultural communication in nursing education are provided.
Content Validation of Instruments: Are the Perspectives of Anglo Reviewers Different From Those of Hispanic/Latino and American Indian Reviewers?
Authors: Evans Bronwynne C.
Published: February 2020

This article reports on the content validation of eight quantitative instruments developed to evaluate the interventions and outcomes for a Nursing Workforce Diversity Grant. During the expert review phase of the content validation process, response patterns to certain instrument items differed, effectively separating the reviewers into two groups. The response patterns of the Hispanic/Latino and American Indian experts were aligned with one another. The responses of the Anglo reviewers were also aligned with one another but not with the responses of the other group, which evaluated as highly relevant instrument items that were organized around five themes: the Importance of a Personal Relationship with Students of Color; the Effect of Isolation from Home and Family; the Importance of Culture and Ethnicity in Personal Identity; the Need for Collaborative, Interactive Learning and a Curriculum of Inclusion; and the Presence of Prejudice, Discrimination, and Racism.
Hablamos Español: Crossing Communication Barriers with the Latino Population
Authors: Amerson Roxanne , Burgins Shelley
Published: February 2020

This article outlines the retrospective study of a pilot project to teach Spanish phrases related to health care to students of an associate degree nursing program. This project was initiated in response to the documented increase in the Latino population in upstate South Carolina. In the decade from 1990 to 2000, four counties in this region documented increases in the Latino population at greater than 60%.

The nursing faculty began teaching simple Spanish phrases prior to each lecture and provided opportunities for students to earn extra credit points on unit examinations for correct translations. The planning and implementation process is described, and descriptive statistics are documented to provide a basic evaluation of success rates for the participating students. The focus of this project was to facilitate communication with Latino clients by teaching students common phrases and simple questions in the Spanish language.

Published: February 2020

Baccalaureate nursing programs must find innovative methods to transform educational culture to value and reward excellence in caring for older adults. Mennonite College of Nursing at Illinois State University used a multidimensional approach to engage college constituents and change the way baccalaureate students are prepared to care for older adults. The college engaged faculty, students, and the community in exchange activities that focused on generating excitement for geriatric nursing within the college and the community. Engaging college constituents enabled large numbers of individuals to work toward creating an educational culture that values and rewards excellence in geriatric nursing.
The Breastfeeding Case Study: A Model for Educating Nursing Students
Authors: Spatz Diane L.
Published: February 2020

Due to several national initiatives and recommendations from professional organizations, more women may be encouraged to breastfeed. However, they will not achieve improvement in breastfeeding duration if their health care providers lack knowledge about breastfeeding or are not easily accessible in some areas. Nurses who work with families with children are responsible for a great deal of patient education and can affect women's decisions to initiate and continue breastfeeding. Therefore, it is critical that nurse educators find a way to address this knowledge gap, especially in already overburdened curricula. This article describes a successful model for doing so.
Incorporating Research into Associate Degree Nursing Curricula
Authors: McEnroe Ayers Denise M. , Coeling Harriet
Published: February 2020

All nurses are urged to be involved in research as participants and/or consumers. Such involvement may range from using research findings to participating in one or more of the research process steps to serving as principle investigator of a funded study. Clinicians at the bedside, including associate degree (AD) nurses, are well positioned to contribute to the body of nursing knowledge and enhance nursing care by identifying nursing care problems worthy of research, collecting data for nursing studies, and applying research findings in the care they provide.

Minimal literature has addressed the preparation of AD students to assist in the research process. In this article, we describe how one AD program prepared students for their role as research participants. Content about the research process was presented in an easy-to-understand, clinically focused manner, and a brief research experience was provided to motivate and prepare these students for research involvement as nurses prepared at the AD level. The educational objectives were met, although time constraints limited students' opportunity to learn about research.
California's Minority Majority and the White Face of Nursing
Authors: Seago Jean Ann , Spetz Joanne
Published: February 2020

Of the 33 million people in California, the nation's most populous state, minority groups now constitute the majority of the population. Many sources predict that by 2060, the entire country will mirror the diversity of California today. Like the rest of the country, California is experiencing a critical shortage of nurses that is predicted to increase in the coming years, and California's nursing workforce does not represent the racial and ethnic diversity of the state's population as a whole. If the nursing profession is to thrive in the coming years, educators and leaders must create a way to embrace people from diverse ethnicities and cultures. The purposes of this article are to determine whether ethnic minority groups have different success rates in California nursing programs, whether nursing programs with high percentages of diverse students have differing success rates, and to describe the institutional predictors of on-time completion rates, attrition rates, and NCLEX-RN

Published: February 2020

The aim of this study was to employ the principal component technique to physiological data and environmental thermohygrometric variables correlated with detection of clinical and subclinical mastitis in dairy cattle. A total of 24 lactating Girolando cows with different clinical conditions were selected (healthy, and with clinical or subclinical mastitis). The following physiological variables were recorded: udder surface temperature, ST (°C); eyeball temperature, ET (°C); rectum temperature, RT (°C); respiratory frequency, RF (mov. min-1). Thermohygrometric variables included air temperature, AirT (°C), and relative humidity, RU (%). ST was determined by means of thermal images, with four images per animal, on these quarters: front left side (FL), front right side (FR), rear right side (RR) and rear left side (RL), totaling 96 images. Exploratory data analysis was run through multivariate statistical technique with the employment of principal components, comprehending nine variables: ST on the FL, FR, RL and RR quarters; ET, RT; RF, AirT and RU. The representative quarters of the animals with clinical and subclinical mastitis showed udder temperatures 8.55 and 2.46° C higher than those of healthy animals, respectively. The ETs of the animals with subclinical and clinical mastitis were, respectively, 7.9 and 8.0% higher than those of healthy animals. Rectum temperatures were 2.9% (subclinical mastitis) and 5.5% (clinical mastitis) higher compared to those of healthy animals. Respiratory frequencies were 40.3% (subclinical mastitis) and 61.6% (clinical mastitis) higher compared to those of healthy animals. The first component explained 91% of the total variance for the variables analyzed. The principal component technique allowed verifying the variables correlated with the animals' clinical condition and the degree of dependence between the study variables.
Sugarcane with Elephant grass replacing sugarcane with urea in the diet of crossbred dairy cows1
Authors: Teixeira César Roberto Viana , Lana Rogério de Paula , Gomes Luiz Henrique dos Santos
Published: February 2020

The objective was to evaluate the partial substitution of sugarcane treated with urea by elephant grass in the feeding of crossbred cows in lactation. Eight crossbred cows (Holstein x Gyr) were used, with 474 kg of body weight (standard deviation = 46.15 kg) and 8.15 kg of milk per day. The animals were housed in individual stalls, distributed in two 4 x 4 Latin squares, and the treatments were: sugar cane; sugar cane corrected with 0.5% of urea and ammonium sulfate (9:1); 75% of sugar cane + 25% of elephant grass and 50% of sugarcane + 50% of elephant grass, based on natural matter. In addition to the treatments, it was provided water and mineral salt ad libitum and 3 kg of concentrate supplement (24% crude protein), based on corn meal and soybean meal, supplied in two portions during the morning and afternoon milking. There was a treatment effect on the intake and digestibility of dry matter and nutrients, except for non-fibrous carbohydrate intake, and there was no effect on milk production and composition. It can be concluded that the substitution of sugarcane by elephantgrass (25 and 50%) increases the intake and decreases the digestibility of DM and OM, without affecting milk production, when the cows are supplemented with 3 kg of concentrate, containing 24% of protein per day.

Created fibroin films (FF) are then evaluated in some characteristics such as surface structure, chemical structure, tensile strength, absorbency, dehydration rate, biodegradation ability, pH determination, preventing bacteria ability and cytotoxicity test. Results: All results indicated that created FF is fulfilled with all the required properties of wound dressings. Conclusions: This study is the first step to creating foundation and orientation for the development of commercial wound dressings.
Preparation and Characterization of Akermanite/Merwinite Scaffolds for Bone Tissue Repair
Authors: Ansari Mojtaba , Malmir Farzad , Salati Amir
Published: February 2020

The ceramics in the system CaO–MgO–SiO2 has recently attracted a great deal of attention because they display a good in vitro bioactivity and have potential use as bone implants. Biphasic calcium-magnesium-silicate ceramics were prepared by a sol-gel method. The dried gel with chemical composition 3CaO.MgO.2SiO2 was thermally treated at 1200 °C for 2 hrs. The structural behavior of the synthesized ceramics was examined by means of X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Merwinite crystalline phase and akermanite phase were recognized. Then, porous akermanite/merwinite scaffolds were prepared to utilize polymer sponge method and evaluated by employing SEM. Furthermore, bone marrow stromal cells (BMSC) adhesion and proliferation on the scaffolds were evaluated by MTT assay test. Differentiation of the cells was assessed by measuring alkaline phosphatase (ALP) activity. The results demonstrated that BMSC adhered and spread well on akermanite scaffolds and proliferated with the increase in the culture time, and the differentiation rate of osteoblasts on scaffolds was comparable to that on blank culture plate control. Thus, the obtained results presented that the akermanite/merwinite scaffolds deserve attention for bone tissue engineering applications.
Non-crop habitats serve as a potential source of spotted-wing drosophila (Diptera: Drosophilidae) to adjacent cultivated highbush blueberries (Ericaceae)
Authors: Urbaneja-Bernat Pablo , Polk Dean , Sanchez-Pedraza Fernando , Benrey Betty , Salamanca Jordano , Rodriguez-Saona Cesar
Published: February 2020

Native to southeast Asia, the spotted-wing drosophila (Drosophila suzukii (Matsumura); Diptera: Drosophilidae) has become a major pest of small fruits in the Americas and Europe. Field studies were conducted over a two-year period (2015–2016) in cultivated highbush blueberry (Vaccinium corymbosum Linnaeus; Ericaceae) fields and adjacent non-crop habitats containing wild blueberries in New Jersey (United States of America). We tracked seasonal changes in D. suzukii adult abundance and fruit infestation throughout the ripening period (June–August). In both years, D. suzukii adult counts post-harvest were generally higher in traps located in non-crop habitats compared with those located in highbush blueberry fields. Wild and cultivated fruits synchronised in maturation, and the numbers of eggs laid and of emerged adults in both fruit types were comparable for most of the season, although sometimes these numbers were higher in wild fruits post-harvest. Overall, immature success (measured as the per cent egg-to-adult survival) was also mostly higher in wild than in cultivated fruits. Altogether, these studies document that non-crop habitats, and wild hosts therein, are used by D. suzukii during fruit ripening and may serve as potential sources of infestation to nearby highbush blueberry fields. Hence, methods that reduce D. suzukii populations in non-crop habitats may help manage this pest in neighbouring highbush blueberries.
DEVELOPMENT OF AN IMPROVED EPSTEIN-BARR VIRUS (EBV) NEUTRALIZING ANTIBODY ASSAY TO FACILITATE DEVELOPMENT OF A PROPHYLACTIC GP350-SUBUNIT EBV VACCINE
Authors: Liu Hui , Gemmell Lorraine , Lin Rui , Zuo Fengrong , Balfour Henry H. , Woo Jennifer C. , Hayes Gregory M.
Published: February 2020

No licensed vaccine is available for prevention of EBV-associated diseases, and robust, sensitive, and high-throughput bioanalytical assays are needed to evaluate immunogenicity of gp350 subunit-based candidate EBV vaccines. Here we have developed and improved analytical tools for such a vaccine’s pre-clinical and clinical validation including a gp350-specific antibody detection assay and an EBV-GFP based neutralization assay for measuring EBV specific antibodies in human donors. The sensitivity of our previously published high-throughput EBV-GFP fluorescent focus (FFA)-based neutralization assay was further improved when guinea pig complement was supplemented using a panel of healthy human sera. Anti-gp350 antibody titers, which were evaluated using an anti-gp350 IgG ELISA assay optimized for capture and detection conditions, were moderately correlated to the FFA-based neutralization titers. Overall, these sensitive, and high-throughput bioanalytical assays are capable of characterizing the serologic response to natural EBV infection, with applications in evaluating EBV antibody status in epidemiologic studies and immunogenicity of candidate gp350-subunit EBV vaccines in clinical studies.

Limits of conjugacy classes under iterates of hyperbolic elements of Out($\mathbb F$)
Authors: Ghosh Pritam
Published: February 2020

For a free group

\mathbb F

of finite rank such that rank

(\mathbb F) \geq 3

, we prove that the set of weak limits of a conjugacy class in

\mathbb F

under iterates of some hyperbolic

\phi \in \mathrm {Out} (\mathbb F)

is equal to the collection of generic leaves and lines with endpoints in attracting fixed points of

\phi

.

As an application we describe the ending lamination set for a hyperbolic extension of

\mathbb F

by a hyperbolic element of Out(

\mathbb F

) in a new way and use it to prove results about Cannon–Thurston maps for such extensions. We also use it to derive conditions for quasiconvexity of finitely generated, infinite index subgroups of

\mathbb F

in the extension group. These results generalize similar results obtained in [23] and [19] and use different techniques.
Free subgroups of 3-manifold groups

Published: February 2020

We show that any closed hyperbolic 3-manifold

M

has a co-final tower of covers

M_i \to M

of degrees

n_i

such that any subgroup of

\pi_1(M_i)

generated by

k_i

elements is free, where

k_i \ge n_i^C

and

C = C(M) > 0

. Together with this result we prove that

\log k_i \ge C_1 \operatorname{sys}_1(M_i)

, where

\operatorname{sys}_1(M_i)

denotes the systole of

M_i

, thus providing a large set of new examples for a conjecture of Gromov. In the second theorem

C_1 > 0

is an absolute constant. We also consider a generalization of these results to non-compact finite volume hyperbolic 3-manifolds.

Authors: Karpowicz Izabela , Suphaphiphat Nujin
Published: February 2020

Advanced economies have been witnessing a pronounced slowdown of productivity growth since the global financial crisis that is accompanied in recent years by a withdrawal from trade integration processes. We study the determinants of productivity slowdown over the past two decades in four closely integrated European countries, Austria, Denmark, Germany and the Netherlands, based on firm-level data. Participation in global value chains appears to have affected productivity positively, including through its effect on TFP when facilitated by higher investment in intangible assets, a proxy for firm innovation. Other contributors to productivity growth in firms are workforce aging, access to finance, and skills mismatches.
Discerning Good from Bad Credit Booms

Credit booms are a focal point for policymakers and scholars of financial crises. Yet our understanding of how the real sector behaves during booms, and why some booms may go bad, is limited. Despite a large and growing body of literature, most of the work has focused on aggregate economic activity, and relatively little is known about which industries benefit and which suffer during these episodes. This note aims to fill this gap by analyzing disaggregated output and employment data in a large sample of advanced and emerging market economies between 1970 and 2014.
Public Sector Debt Definitions and Reporting in Low-Income Developing Countries
Authors:   International Monetary Fund,   World Bank
Published: February 2020

Increasing public debt vulnerabilities in low-income developing countries (LIDCs)
have heightened the need for fuller and more transparent accounting of public
sector debt (PSD).
The framework for reporting on public sector debt is sound. But there is room for LIDCs to further improve their compilation, reporting, and dissemination of public sector debt data in international databases and more
broadly the public domain.
Commercial Microwave Links as a tool for operational rainfall monitoring in Northern Italy

Abstract. There is a growing interest in emerging opportunistic sensors for precipitation estimates, motivated by the need to describe with detail precipitation structures. In this work a preliminary assessment of the accuracy of Commercial Microwave Links (CMLs) retrieved rainfall rates in northern Italy is presented. The CML product, obtained by the publicly available RAINLINK package, is evaluated at different scales (single link, 5 km x 5 km grid, river basin) against the precipitation products operationally used at Arpae-SIMC, the Regional Weather Service of Emilia-Romagna, in northern Italy. The results of the 15 min single-link validation with close-by raingauges show high variability, with influence of the area physiography and precipitation patterns and the impact of some known issues (e.g. melting layer). However, hourly cumulated spatially interpolated CML rainfall maps, validated with respect to the established regional gauge-based reference, show performances (R2 of 0.47 and CV of 0.77) which are very similar, when not even better, to satellite- and adjusted radar-based precipitation gridded products. This is especially true when basin-scale total precipitation amounts are considered (R2 of 0.85 and CV of 0.63). Taking into account also delays in the availability of the data (latency of 0.33 hours for CML against 1 hour for the adjusted radar and 24 h for the quality controlled raingauges), CMLs appear as a valuable data source in particular from a local operational framework perspective. A diffuse underestimation is evident at both grid box (Mean Error of −0.26) and basin scale (Multiplicative Bias of 0.7), while the number of false alarms is generally low and gets even lower as coverage increases. Finally, results show complementary strengths for CMLs and radars, encouraging a joint exploitation.

This study aimed to determine nutrient metabolizability coefficients and apparent metabolizable energy (AME) and nitrogen-corrected AME (AMEn) values of moringa leaf meal and bocaiuva pulp for slow-growing broilers. Three hundred and fifty 1-day-old chicks of the Red Naked Neck line were allocated to five treatments in a completely randomized design with seven replicates of 10 birds. Treatments consisted of a control diet and four test diets. The proportion of ingredients evaluated in the test diets was 20% moringa leaf meal and bocaiuva pulp and 40% corn and soybean meal. The total excreta collection method was applied with 1% ferric oxide included in the diets as a marker of start and end of collection, in the starter, grower and finisher phases. The metabolizability coefficients of dry matter, crude protein and ether extract and the AME and AMEn values of moringa leaf meal, bocaiuva pulp, corn and soybean meal were determined. Data were subjected to analysis of variance and means were compared by Tukey’s test at the 5% probability level. The protein from moringa leaf meal and the fat from bocaiuva pulp are highly metabolizable by birds at different ages. The AME and AMEn values of moringa leaf meal ranged from 2557 to 2868 Kcal/kg and 2205 to 2479 Kcal/kg, respectively. In bocaiuva pulp, AME and AMen ranged between 2680 and 3119 Kcal/kg and 2483 and 2490 Kcal/kg, respectively. Therefore, the alternative ingredients can be used in the formulation of diets for slow-growing broilers to partially replace corn and soybean meal.
The head of the nominal is N, not D: N-to-D Movement, Hybrid Agreement, and conventionalized expressions
Authors: Bruening Benjamin
Published: February 2020

The DP Hypothesis has recently come under intense criticism (Bruening 2009, Bruening et al. 2018). In the face of this criticism, several responses have been offered. This paper addresses three such responses and shows that they are without force. First, N-to-D movement is not necessary in Shona, as Carstens (2017) claims. Second, patterns of hybrid agreement in Bosnian-Croatian-Serbian do not require the DP Hypothesis, as Salzmann (2018) claims. Third, patterns of conventionalized expressions show that there is a close syntactic relation, possibly selection, between a selecting head and N, contra Salzmann (2018). The patterns of conventionalized expressions are incompatible with the DP Hypothesis and require that the head of the nominal is N, not any functional head. Functional heads inside nominals have to be dependents of the head N, not vice versa.
APP GeoGebra Graphing Calc: articulações da Matemática e tecnologias na Educação Básica
Authors: Moro Fernanda Teresa , Rossatto Scheila Andretta
Published: February 2020

O ensino da Matemática, em muitos contextos, ainda se encontra desvinculado das tecnologias. Os recursos, como as tecnologias digitais, de maneira geral, são pouco utilizados nos processos de ensino e de aprendizagem nas diferentes disciplinas, aspecto esse reforçado pela carência de formação tecnológica dos professores e pela cultura escolar predominante, na qual há ênfase à abordagem expositiva do conhecimento. O enfoque, na maioria das vezes, tem consistido na transmissão do conteúdo matemático escolar, uma vez que o ensino nas aulas de matemática ocorre frequentemente mediante a apresentação de conceitos, leis e fórmulas, de forma desarticulada, vazios de significado e distanciados das tecnologias digitais, constituindo-se em um entrave no aprendizado. O uso de tecnologias tem sido frequentemente apontado, em discussões acadêmicas, como relevante recurso didático. As tecnologias digitais podem assumir uma importância fundamental na promoção de aprendizagens significativas em matemática, pois ajudam os alunos a aprender através do estabelecimento de inter-relações entre os saberes teóricos e práticos inerentes aos processos do conhecimento escolar. Neste contexto, este trabalho apresenta um relato de experiência desenvolvido no 1º ano do Ensino Médio em uma escola da rede privada do município de Erechim, RS. O objetivo do trabalho é desenvolver e investigar ações de intervenção para problematizar e aprimorar o ensino de Matemática, possibilitando a exploração de funções de 1º e 2º graus com recursos tecnológicos. Para este trabalho foi utilizado o APP GeoGebra Graphing Calc, que permite o uso nos próprios Smartphones dos estudantes. Espera-se que este trabalho possa contribuir a outros professores para que os mesmos passem a incorporar as tecnologias em sua prática pedagógica.
Democratização da educação superior: nexos entre a afirmação da excelência e o desafio do reconhecimento
Authors: Grisa Gregório Durlo , Caregnato Célia Elizabete
Published: February 2020

As universidades públicas federais brasileiras vivem um importante processo de democratização. Assegurado majoritariamente pela Lei 12.711/2012, ele expõe novas dinâmicas e contradições. Este artigo discute a relação entre excelência acadêmica e o reconhecimento institucional aos novos públicos que ingressam nessas instituições. A base empírica é constituída por oito entrevistas com gestores que ocupam cargos acadêmicos de destaque em uma universidade pública comprometida com a excelência acadêmica, conforme seus documentos oficiais. Para a discussão dos dados, recorremos à ideia de excelência acadêmica e à noção de reconhecimento. Elas apoiam a compreensão de que se está tratando de um universo institucional tensionado entre o objetivo de ser excelente e o de exercer sua função social. Para cumpri-los, a universidade precisa desenvolver formas de lidar com públicos estudantis não tradicionais, os quais crescentemente estão presentes no cotidiano institucional. Concluímos que o processo de democratização em uma instituição que busca afirmação com base na excelência acadêmica necessita reafirmar práticas que ofereçam condições aos novos públicos de estudantes para alcançarem, além do acesso, espaços de prestígio e sucesso acadêmico.
