Tranexamic Acid in the Treatment of Hip Fractures: A Clinical Review
Authors: Krebs Nathan M. , VanWagner Michael J. , Marchewka Tiffany , Faraj Usama , Vitale Christopher R.
Published: February 2021

INTRODUCTION

Although regularly used as a method to reduce blood loss in elective orthopedic procedures (e.g., total hip and knee arthroplasty), there currently is little evidence concerning the optimal dosage, timing and route for the use of tranexamic acid to reduce postoperative blood loss in hip fracture repair.

SUMMARY OF THE EVIDENCE

The current literature suggests that tranexamic acid may be used to reduce postoperative blood loss in addition to reducing the risk of requiring blood transfusions following the surgical repair of hip fractures. Furthermore, it may have the potential to improve patient outcomes and decrease the overall costs of caring for this patient population.

CONCLUSIONS

Further studies are needed to truly gauge the effect of tranexamic acid on long-term patient outcomes and hospital costs.

Authors: Grill Justin , Bryant Caleb , Dunikoski Leonard , Carrasco Zach , Wisniewski Samuel J. , Price Kristen
Published: February 2021

CONTEXT

Currently, there is no standard therapy for treatment of acute renal colic. With the increased scrutiny and controversy now surrounding opioids, the authors identified a need to investigate an alternative medication for pain control. As such, they sought to determine the efficacy of sub-dissociative (i.e., low) doses (0.3 mg/kg) of ketamine in providing Emergency Department (ED) patients acute pain management for renal colic secondary to nephrolithiasis.

METHODS

After institutional review board (IRB) approval, the authors conducted a non-blinded, prospective clinical study. A convenience sample of n = 34 patients from the ED of a Western Michigan-based health system with suspected renal colic received one intravenous dose of ketorolac, 30 mg if over 50 kg body weight or 15 mg if under 50 kg In patients weighing greater than 50 kg, up to two doses of sub-dissociative ketamine were then given to further control pain. Pain was assessed at times 0, 30, 60, 90 and 120 minutes.

RESULTS

There was a statistically significant pain reduction with administration of sub-dissociative ketamine, with 24 (69.2%) patients reporting an average reduction in pain score > 30% (t = 3.16, p = 0.004). Initial average pain scores for patients receiving sub-dissociative ketamine averaged 7.76 (SD = 2.55) on the 11-point verbal Pain Numeric Rating Scale. After a first dose of ketamine, patients’ average pain score was 3.56 (SD = 0.74) at 30 minutes. After two hours, patients’ average score was 2.56 (SD = 0.65), indicating that pain control was still effective over time with no statistically significant change in pain scores. Additionally, there was no statistically significant difference in pain reduction observed between genders (t = -0.192, p = 0.850).

CONCLUSIONS

Based on these results, sub-dissociative ketamine may be considered a reasonable and effective supplemental non-opiate treatment option for suspected renal colic in otherwise healthy 18-70-year-old patients and could provide an effective alternative to traditional therapies. Further studies utilizing this methodology with larger, more generalizable samples are needed to further validate these findings.

Published: February 2021

INTRODUCTION

The aim of this study is to evaluate the relationship between Breast Imaging Reporting and Data System and surgical biopsies that may increase effectiveness of wire-guided percutaneous localizations for non-palpable breast lesions.

METHODS

A retrospective review of a sample of 149 patients who underwent wire-guided localization with wide local excision for non-palpable breast lesions at the authors’ institution between January 2013 and April 2016. After IRB approval, sample patients’ records were reviewed and data were collected concerning their radiological, histological and surgical characteristics.

RESULTS

One (0.67%) complication occurred related to wire migration. There were nine (6.04%) recorded cases of seroma and three (2.01%) cases of hematoma. Breast Imaging Reporting and Data System (BI-RADS) Category 4 was found to have a positive predictive value of 28.4% for breast cancer. Under Category 4 subcategorization 4A, 4B, and 4C, the number of positive lesions were two (6.89%), three (10.34%) and five (17.24%), respectively. Forty (78.43%) of the 51 patients with cancer had negative (i.e., non-cancerous) margins compared to 11 (21.57%) cases that had positive margins after the first procedure.

CONCLUSION

The BI-RADS Category 4 encompasses the majority of lesions, with approximately 70% of such biopsies lesions later found to be benign. A subcategorization of BI-RADS 4 needs further clarification in distinguishing benign vs malignant imaging characteristics. Future retrospective studies designed to identify benign vs. malignant lesions, confirmed by validating prospective studies, will better clarify a new subcategorization of BI-RADS Category 4, thus allowing surgeons and radiologists to make the best surgical recommendations for their patients.
Do Not Let it Be the Last: End-of-Life Care Decisions in the Primary Care Clinic

Published: February 2021

CONTEXT

For many patients, end-of-life care (EOLC) wishes are unknown and are generally only brought up during healthcare crises. During such healthcare episodes, loved ones are often distraught, and as such, can find it difficult to focus on details surrounding the event. The best place for these discussions may be in non-acute settings including primary care clinics. The purpose of this study was to examine how well a sample of patients (N = 177) in three Michigan-based primary care teaching clinics thought they and their loved ones were prepared in terms of having their EOLC wishes known.

METHODS

Prospective data were collected from three Internal Medicine teaching clinics in the Metro-Detroit area through an anonymous written survey addressing EOLC issues in a 16-item cross-sectional study. Respondents were adult patients at one of three participating primary care clinics. Perceived preparedness for EOLC was measured by: 1) possibly having had a prior EOLC discussion with a healthcare provider 2) having created an Advance Directive, such as a Durable Power of Attorney (DPOA) or Living Will with medical decision preferences, 3) reported preferences for quality versus quantity of life, and 4) preferences for CPR and other specific life-sustaining interventions.

RESULTS

In this sample, 77 (43.5%) of 177 respondents had discussed their EOLC wishes with a provider. Regarding Advance Directives, 63/177 (35.6%) had established a DPOA, and 59/177 (22%) had made a Living Will. The majority of respondents preferred quality over quantity of life. The most difficult EOLC questions included the decision for CPR, tracheostomy, and PEG tube placement.

CONCLUSIONS

Based on these results, EOLC discussions probably occur infrequently in the primary care or other healthcare settings. Most survey responses indicated that sample patients were unprepared concerning the details of future EOLC decisions. Engagement of such discussions should be a part of routine visits in the primary care clinic and should be re-visited when there is a change in a patient’s health. Further larger-scale studies using validated surveys are required in this vitally important area of practice. Key Words: advance care planning, end-of-life care conversations, primary care

Abstract An apple is a fruit that is widely planted in mountainous or cold regions, for example in Malang. Apples are fruits that have many colors, there are green, yellow, and red colors. With a variety of colors that make consumers feel confused whether the apples to be eaten are sweet or sour. Because almost most consumers do not know the type of apple that will be purchased. Sometimes the type of apple that will be purchased is green, but because it does not know ripe or raw, it is wrong to choose. In order to help consumers in knowing the level of maturity of apple again, a system was made. With the aim to be able to classify the level of maturity of the apple again. So that the system created will display information whether the apple is more ripe or raw. The system will process the image of the apple again and take the GLCM texture features (intensity, contrast, energy, smoothness, entropy, skewness). And the process of determining fruit maturity using the KNN method. The system was built using the matlab tool, with 200 datasets, consisting of 130 training datasets, and 70 testing datasets. In applying the KNN algorithm to determine the maturity level of apples, the accuracy results are 51.4%.

Abstract. Polar stratospheric clouds (PSCs) have been observed from 2014 to 2018 from the lidar observatory at the Antarctic Concordia station (Dome C), included as a primary station in the NDACC (Network for Detection of Atmospheric Climate Change).
Many of these measurements have been performed in coincidence with overpasses of the satellite-borne CALIOP (Cloud Aerosol Lidar with Orthogonal Polarization) lidar, in order to perform a comparison in terms of PSC detection and composition classification. Good agreement has been obtained, despite intrinsic differences in observation geometry and data sampling. This study reports, to our knowledge, the most extensive comparison of PSC observations by ground-based and satellite-borne lidars. The PSCs observed by the ground-based lidar and CALIOP form a complementary and congruent dataset and allow us to study the seasonal and interannual variations in PSC occurrences at Dome C.
Moreover, a strong correlation with the formation temperature of NAT (nitric acid trihydrate), TNAT, calculated from local temperature, pressure, and H2O and HNO3 concentrations is shown. PSCs appear at Dome C at the beginning of June up to 26 km and start to disappear in the second half of August, when the local temperatures start to rise above TNAT. Rare PSC observations in September coincide with colder air masses below 18 km.
Effect of mixing structure on the water uptake of mixtures of ammonium sulfate and phthalic acid particles

Published: February 2021

Abstract. Aerosol mixing state regulates the interactions between water
molecules and particles and thus controls aerosol activation and
hygroscopic growth, which thereby influences visibility degradation,
cloud formation, and its radiative forcing. There are, however, few current studies on the mixing
structure effects on aerosol hygroscopicity.
Here, we investigated the hygroscopicity of ammonium
sulfate / phthalic acid (AS / PA) aerosol particles with
different mass fractions of PA in different mixing states in terms of
initial particle generation. Firstly, the effect of PA coatings
on the hygroscopic behavior of the core-shell-generated mixtures of AS with PA was studied using a coating hygroscopicity tandem
differential mobility analyzer (coating HTDMA). The slow increase in the
hygroscopic growth factor of core-shell-generated particles is observed with
increasing thickness of the coating PA prior to the deliquescence
relative humidity (DRH) of AS. At relative humidity (RH) above 80 %,
a decrease in the hygroscopic growth factor of particles occurs as the thickness
of the PA shell increases, which indicates that the increase of PA mass
fractions leads to a reduction of the overall core-shell-generated particle
hygroscopicity. In addition, the use of the Zdanovskii–Stokes–Robinson (ZSR) relation leads to the
underestimation of the measured growth factors of core-shell-generated
particles without consideration of the morphological effect of
core-shell-generated particles, especially at higher RH. Secondly, in the
case of the AS / PA initially well-mixed particles, a shift of the DRH of AS (∼80 %, Tang and Munkelwitz, 1994) to lower RH is observed due to the presence of
PA in the initially well-mixed particles. The predicted hygroscopic growth
factor using the ZSR relation is consistent with the measured hygroscopic
growth factor of the initially well-mixed particles. Moreover, we compared
and discussed the influence of mixing states on the water uptake of AS / PA
aerosol particles. It is found that the hygroscopic growth factor of the
core-shell-generated particles is slightly higher than that of the initially
well-mixed particles with the same mass fractions of PA at RH above 80 %.
The observation of AS / PA particles may contribute to a growing field of
knowledge regarding the influence of coating properties and mixing structure
on water uptake.
The transformation of the forest steppe in the lower Danube Plain of southeastern Europe: 6000 years of vegetation and land use dynamics

Abstract. Forest steppes are dynamic ecosystems, highly susceptible to changes in
climate, disturbances and land use. Here we examine the Holocene history of
the European forest steppe ecotone in the lower Danube Plain to better
understand its sensitivity to climate fluctuations, fire and human impact,
and the timing of its transition into a cultural forest steppe. We used
multi-proxy analyses (pollen, n-alkanes, coprophilous fungi, charcoal and
geochemistry) of a 6000-year sequence from Lake Oltina (southeastern Romania) combined
with a REVEALS (Regional Estimates of Vegetation Abundance from Large Sites) model of quantitative vegetation cover. We found a greater tree cover, composed of xerothermic (Carpinus orientalis and Quercus) and temperate (Carpinus betulus, Tilia, Ulmus and Fraxinus) tree taxa,
between 6000 and 2500 cal yr BP. Maximum tree cover (∼ 50 %), dominated by C. orientalis occurred between 4200 and 2500 cal yr BP at a time of
wetter climatic conditions and moderate fire activity. Compared to other
European forest steppe areas, the dominance of C. orientalis represents the most distinct
feature of the woodland's composition at this time. Tree loss was underway
by 2500 yr BP (Iron Age), with the REVEALS model indicating a fall to
∼ 20 % tree cover from the Late Holocene forest maximum,
linked to clearance for agriculture, while climate conditions remained wet.
Biomass burning increased markedly at 2500 cal yr BP, suggesting that fire
was regularly used as a management tool until 1000 cal yr BP when woody
vegetation became scarce. A sparse tree cover, with only weak signs of
forest recovery, then became a permanent characteristic of the lower Danube
Plain, highlighting more or less continuous anthropogenic pressure. The
timing of anthropogenic ecosystem transformation here (2500 cal yr BP) falls between that in central-eastern (between 3700 and 3000 cal yr BP) and
eastern (after 2000 cal yr BP) Europe. Our study is the first quantitative
land cover estimate at the forest steppe ecotone in southeastern Europe
spanning 6000 years. It provides critical empirical evidence that, at a
broad spatial scale, the present-day forest steppe and woodlands reflect the
potential natural vegetation in this region under current climate
conditions. However, the extent of tree cover and its composition have
been neither stable in time nor shaped solely by the climate. Consequently,
vegetation change must be seen as dynamic and reflecting wider changes in
environmental conditions including natural disturbances and human impact.
Key drivers of pyrogenic carbon redistribution during a simulated rainfall event
Authors: Bellè Severin-Luca , Berhe Asmeret Asefaw , Hagedorn Frank , Santin Cristina , Schiedung Marcus , van Meerveld Ilja , Abiven Samuel
Published: February 2021

Abstract. Pyrogenic carbon (PyC) is produced by the incomplete combustion of
vegetation during wildfires and is a major and persistent pool of the global
carbon (C) cycle. However, its redistribution in the landscape after fires
remains largely unknown. Therefore, we conducted rainfall simulation
experiments on 0.25 m2 plots with two distinct Swiss forest soils
(Cambisol (clay loam) and Luvisol (sandy silt)). We applied PyC produced
from wood (Picea abies) labeled under FACE conditions and C4 grass (Miscanthus sinensis) to the soil
surface to study PyC redistribution by runoff and splash and the vertical
mobility of PyC in a 10 cm unsaturated soil column based on the differences
in δ13C of soils and PyC. We assessed the effect of soil
texture, slope angle and PyC characteristics (feedstock and particle size)
on the mobility of PyC during 30 min of intense rainfall
(102 mm h−1). Our results highlight that PyC is highly mobile. Surface
runoff transported between 0.2 % and 36.0 % of the total added PyC. Erosion
by splash further redistributed 10.3 % to 25.3 % of the added PyC. Soil
type had a substantial impact on the redistribution of PyC by both runoff
and splash: on average, we recovered 10.5 % of the added PyC in runoff
and splashed material for the clay-rich Cambisol and 61.3 % of the added
PyC for the sandy silt Luvisol combined. PyC feedstock had a clear but
contrasting effect on PyC redistribution: relocation in the runoff and
splashed material was greater for wood PyC (43.4 % of total added PyC)
than grass PyC (28.4 %). However, more wood PyC (11.5 %; fraction of
organic C derived from the PyC) remained where it was initially applied
compared to grass PyC (7.4 %). The results further suggest that the
effect of PyC characteristics on its mobility can be highly variable and
depend not only on the material from which it was derived, but also on other
factors (e.g., particle size, porosity, density). In particular, the mobility
of PyC was almost twice as large for fine-grained PyC (< 63 µm) than for coarse PyC (63 µm–2 mm). Vertical mobility of PyC up
to 10 cm depth was greater in the clay-rich, well-aggregated Cambisol but
limited in the physically instable Luvisol, likely due to quick aggregate
breakdown and surface sealing. The addition of PyC to the surface of the
studied soils further induced changes in the export of native soil organic
carbon (nSOC) after the 30 min rainfall event. Our study shows that
large quantities of PyC can be redistributed by water erosion over short
timescales and that the mobility of PyC depends to a great extent on the
response of soils to rainfall. Moreover, the addition and redistribution of
PyC affects the export of nSOC and thus the C budget of fire-affected soils
and catchments.
Weekly reconstruction of pH and total alkalinity in an upwelling-dominated coastal ecosystem through neural networks (ATpH-NN): The case of Ría de Vigo (NW Spain)
between 1992 and 2019
Authors: Broullón Daniel , Pérez Fiz F. , Doval María Dolores
Published: February 2021

Abstract. Short and long-term variability of seawater carbon dioxide (CO2) system shows large differences between different ecosystems which are derived from the characteristic processes of each area. The high variability of coastal ecosystems, their ecological and economic significance, the anthropogenic influence on them and their behavior as sources or sinks of atmospheric CO2, highlight the relevance to better understand the processes that underlie the variability and the alterations of the CO2 system at different spatiotemporal scales. To confidently achieve this purpose, it is necessary to have high-frequency data sustained over several years in different regions. In this work, we contribute to this need by configuring and training two neural networks with the capacity to model the weekly variability of pH and total alkalinity (AT) in the upper 50 m of the water column of the Ría de Vigo (NW Spain), with an error of 0.031 pH units and 10.9 µmol kg−1 respectively. With these networks, we generated weekly time series of pH and AT in seven locations of the Ría de Vigo in three depth ranges (0–5 m, 5–10 m and 10–15 m), which adequately represent independent discrete measurements. In a first analysis of the time series, a high short-term variability is observed, being larger for the inner stations of the Ría de Vigo. The lowest values of pH and AT were obtained for the inner zone, showing a progressive increase towards the outer/middle zone of the ría. The mean seasonal cycle also reflects the gradient between both zones, with a larger amplitude and variability for both variables in the inner zone. On the other hand, the long-term trends derived from the time series of pH show a higher acidification than that obtained for the open ocean, with surface trends ranging from −0.020 pH units per year in the outer/middle zone to −0.032 pH units per year in the inner zone. In addition, positive long-term trends of AT were obtained ranging from 0.39 µmol kg−1 per year in the outer/middle zone to 2.86 µmol kg−1 per year in the inner zone. The results presented in this study show the changing conditions both in the short and long-term variability as well as the spatial differentiation between the inner and outer/middle zone to which the organisms of the Ría de Vigo are subjected. The neural networks and the database provided in this study offer the opportunity to evaluate the CO2 system in an environment of high ecological and economic relevance, to validate high-resolution regional biogeochemical models and to evaluate the impacts on organisms of the Ría de Vigo by refining the ranges of the biogeochemical variables included in experiments.
Close-to-nature management positively improves the spatial structure of Masson pine forest stands

Published: February 2021

Abstract. Close-to-nature management (CTNM) has been proposed as a promising forestry management approach to improve the structure and quality of forests, which integrates wood production and ecological service functions. Research on the effect of CTNM on the univariate and bivariate distribution of the spatial structure of forest stands provides a scientific basis for the evaluation of CTNM implemented in forestry. Here, we analyzed and compared the spatial-structure characteristics of Masson pine (Pinus massoniana) plantations (young, middle-age, and near-mature stages) under CTNM 8 years after selective cutting and unmanaged control. We used univariate and bivariate distribution of three spatial-structure parameters: mingling (M), dominance (U), and uniform-angle index (W). Results showed that the effect of CTNM on spatial structure was more remarkable in middle-aged and near-mature Masson pine forests compared with the young forest. CTNM significantly improved mingling degree and promoted the horizontal distribution, thereby changing from a cluster to a random distribution. Moreover, CTNM improved the proportion of trees with a high mixing degree and random distribution and the proportion of trees having a micro-structure of random distribution with a high degree of mixture and dominance with a high degree of mixture in middle-aged and near-mature Masson pine forest. Overall, the implementation of CTNM 8 years ago showed a positive effect on the improvement of the spatial structure of Masson pine forest, but the present spatial structure is suboptimal. Further implementation of CTNM to adjust the mingling and uniform-angle index is necessary, and CTNM according to this method of frequency distribution of stand structure parameters can improve the success of forest management.

Essential Self of Natalie Waite in Hangsaman by Shirley Jackson
Authors: Behrens Susan J.
Published: February 2021

In light of a 2016 biography and 2020 feature film about writer Shirley Jackson, contemporary readers are rediscovering Jackson’s work. One novel of interest is Hangsaman (1951). This is a book in motion, with shifting realities and narratives that are mirrored in the author’s naming schemes. Moments of disorientation in Hangsaman originate in, and reflect, the inner life of protagonist Natalie Waite. There seem to be multiple Natalies who struggle at times to be whole, and at other times to be a different person entirely. Along with these vicissitudes in personality, the protagonist takes on variations on the name Natalie. At the point at which she is at the greatest risk of losing herself completely, Natalie adopts a new name, the gender-ambiguous Tony. Natalie is ultimately saved from slipping away and becoming Tony through the author’s device of false starts, i.e., opportunities for characters to relive and rename events in a new light, in a different reality. Natalie’s internal journey has been, all along, tracked by her public and private names.

Se presenta en la siguiente investigación un análisis descriptivo pormenorizado de la producción científica de alto impacto (definida ésta como toda investigación indexada en la base de datos Scopus) de una universidad privada colombiana, la Universidad Tecnológica de Bolívar, durante el período temporal 2017-2019. El objetivo de este trabajo es dilucidar los aspectos positivos y negativos de la implementación de un plan de metas anual relacionado con la producción científica del profesorado de planta de esta entidad educativa superior durante su primer año de vigencia (año 2019). Para ello, se revisó la información de la base de datos Scopus en función de diversas variables tales como el tipo de producto, número de autores, área temática... y su evolución temporal en esos tres años, haciendo también una comparativa con el resto de las universidades de su entorno más cercano. Aunque se logró superar con creces la meta global impuesta (superar el centenar de productos), la asignación de cuotas de producción científica al profesorado profundizó otras tendencias ya existentes en esta universidad como la extrema dependencia del trabajo de ciertos departamentos de ingeniería y la preferencia por publicar conference proceedings y no libros, capítulos de libro o revistas.
Del besalamano al correo electrónico: una aproximación a la correspondencia en los fondos del archivo del congreso de los diputados

La carta es un tipo documental con una importancia muy significativa en el ámbito de la actividad parlamentaria, pues a través de estos documentos se sustancian diversas iniciativas y también se establece un flujo muy variado de comunicación. Las cartas evidencian la comunicación, interna y externa, de las Cortes a lo largo de sus ya más de dos siglos de Historia. Hoy los intercambios epistolares, a través de los que se materializa la comunicación han variado sustancialmente en lo que a su soporte se refiere, y también en muchos de los usos asociados a ellas, pero su capacidad de comunicación sigue intacta. El presente artículo pretende acercarse a esta tipología documental a través de los expedientes que se conservan en el Archivo del Congreso de los Diputados y acercarse a su complejo y múltiple presente para tratar de poner el acento en la necesidad de su conservación.

Tão importante quanto os fatores conjunturais que têm contribuído para a crescente proletarização docente, muitas atitudes e concepções do próprio próprio professor costumam colaborar com este processo, automatizando e descaracterizando sua prática pedagógica.
Os egressos da UEPG e o ensino de história: a formação de professores
Authors: De Carvalho Silvana Maura Batista
Published: February 2021

O trabalho realizado pretendeu avaliar e contribuir para a formação de professores, buscou atingir os objetivos propostos de oferecer subsídios para o curso de licenciatura em História da Universidade Estadual de Ponta Grossa, em especial, à disciplina de Metodologia e Prática de Ensino, extraídos da prática pedagógica do professor. Para isso reportou-se aos egressos do curso, formados no período de 1987-92, a fim de que através da análise de alguns aspectos de sua prática fosse possível estabelecer o perfil do professor formado pela UEPG. Os professores graduados no período indicado sofreram a ação do projeto de estágio supervisionado – Marcos Referenciais da História em Ponta Grossa – implantado em 1990. Esse projeto trouxe novas dimensões ao estágio curricular que, em concordância com o Currículo Básico do Paraná, expressa uma concepção “renovada” para o ensino de História. A preocupação foi a de avaliar se e como tal concepção constitui o suporte teórico-metodológico da atuação do professor, por meio de estratégias docentes utilizadas para sua concretização. A pesquisa possibilitou a indicação de pontos de reflexão para a avaliação do curso , e para novas políticas de formação de professores, no curso de História da UEPG. Entre eles: a necessidade de superação da desarticulação entre as disciplinas do currículo do curso; a sugestão formulada pelos professores que apontam outros aspectos, além dos já atendidos, a serem considerados na formação docente visando atender a dinamicidade da realidade atual. Esses pontos possibilitam indicar a direção a ser dada nos cursos de licenciatura – a formação do “professor reflexivo.”

Escola básica: dois segmentos dissociados
Authors: Ribas Mariná Holzmann , Martins Rosilda Baron , Luporini Teresa Jussara
Published: February 2021

A Escola Básica constituiu-se num campo fértil de estudo e de investigações. Foi com essa perspectiva que se desenvolveu o projeto de pesquisa Escola Básica: dois segmentos dissociados que se originou com a constatação dos altos índices de evasão e repetência na 5a série, gerados pelas dificuldades que os alunos de uma escola pública enfrentavam na passagem das séries iniciais para as finais do 1o grau; tais dificuldades afloraram no desempenho dos alunos e nas queixas dos professores de 5as séries. A análise foi estruturada em três eixos norteadores: a gestão interna da escola, a ação supervisora compartilhada e a disponibilidade dos professores da escola em desenvolver uma proposta que aprimora o fazer pedagógico dos envolvidos. Com isso, foi possível ver que quando existe o comprometimento com uma proposta pedagógica há a possibilidade de participação dos envolvidos na definição de conteúdos e de formas de ação. Além disso, quando efetivamente apoiada/acompanhada pela equipe técnico- administrativa, os resultados são consistentes e produtivos, gerando o sentimento de pertença e poder decisório em relação à unidade escolar.

A educação acontece em diferentes espaços. A mídia também é um desses espaços. Por isso, neste artigo, propusemo-nos a analisar algumas questões, que consideramos relevantes e que, em geral, ocultam a hegemonia de uma classe sobre a outra. No processo educativo que acontece por meio da mídia, há uma contribuição para fortalecer tal hegemonia. Isso comprova a não neutralidade da educação. A mídia tem se mostrado como partido ideológico da elite, e o poder que exerce neste espaço social pode ser definido como poder simbólico, atrelado intimamente ao poder econômico, político e, em alguns casos, até coercitivo. Para discutirmos a mídia como instrumento educativo, em favor da manutenção do status quo, optamos em fazê-lo apresentando como duas temáticas que são por ela tratadas: Gênero e o Movimento dos Trabalhadores Rurais Sem Terra.   Palavras-chave: Mídia. Educação. Consenso. Hegemonia. Gênero. Movimento dos Trabalhadores Rurais Sem Terra.   Education is settled in different places and the media is also one of these places. Therefore, in this article we propose to analyze some relevant questions that can usually hide the hegemony of a class on the other. In the educative process intermediated by the media, we can notice a contribution to empower this hegemony. This put in evidence the education no neutrality position. The media can be understood as an ideological political organization of the upper class and its power can be defined as a symbolic one, linked to the economic and politician forces and even acting, in some cases, as a coercion element. To discuss the media as an educative instrument, in favor of the of the status quo maintenance, we present two thematic that have been followed: Gender and Movimento dos Trabalhadores Rurais Sem Terra (The Movement of the Agricultural Workers With No Land).   Keywords: Media. Education. Consensus. Hegemony. Gender. Movimento dos Trabalhadores Rurais Sem Terra.

Authors: Rosso Ademir José
Published: February 2021

O presente trabalho relata uma pesquisa desenvolvida com a colaboração de 12 alunas do Curso de Pedagogia em Séries Iniciais da Universidade do Alto Vale do Itajaí, Campus de Tijucas - SC. O objetivo da pesquisa foi saber o que os professores das Séries Iniciais do Ensino Fundamental pensavam sobre o planejamento didático, a partir de entrevistas semi-estruturadas. A realização da pesquisa deu-se dentro do contexto da disciplina Prática de Ensino em Didática. Do conjunto dos materiais coletados, respeitando-se a diversidade e a heterogeneidade dos dados, pode-se provisoriamente dizer que os educadores, ao mesmo tempo em que se prendem mais aos aspectos didáticos do ensino, manifestam-se favoráveis à necessidade de se planejar as atividades didático-pedagógicas, rejeitando a verticalização do planejamento presente nos sistemas de educação.
