Authors: Teixeira David Romão , Vilas Bôas Junior Jaildo Calda dos Santos , Ribeiro Alexsandro Rabaioli Nunes , Cruz Eunice Santos da , Beltrão José Arlen
Published: January 2022

O objetivo deste artigo é compartilhar reflexões referentes às nossas experiências com o ensino da Educação Física no Ensino Médio desenvolvidas em dois colégios da rede pública do interior do Estado da Bahia, na primeira unidade escolar de 2021. A construção dos relatos utilizou como fonte de dados: i) os registros e relatórios dos núcleos do Programa de Residência Pedagógica de cada colégio; ii) os documentos oficiais que orientam o Ensino Médio; e iii) os registros de observação dos professores. Os relatos de experiência apontam aspectos importantes sobre o ensino da Educação Física no Ensino Médio em meio à pandemia do COVID-19, como: a) as dificuldades de fazer experimentos práticos no ensino remoto; b) a importância da elaboração de roteiros de estudo; c) a preocupação com o grande quantitativo de estudantes que não participam das atividades síncronas; d) as limitações de avaliar a aprendizagem. Concluímos que não é possível uma Educação Física escolar de qualidade no formato remoto, virtual, ou à distância, uma vez que não é possível garantir no Ensino Médio o aprofundamento dos conteúdos da Cultura Corporal sem a realização das experimentações práticas, em grupo, e sob a responsabilidade de um professor de forma presencial.
Análisis de interpolación espacial de contagios de COVID-19 en la cuenca del río Luján
Authors: Humacata Luis
Published: January 2022

Uno de los factores que se debe tener en cuenta cuando se analiza la propagación de un virus es el geográfico o espacial, que condiciona su proceso de difusión espacial, a partir de las relaciones funcionales que se presentan en el espacio geográfico. El presente trabajo desarrolla la propuesta metodológica basada en el método de interpolación espacial denominado Estimador de Densidad Kernel, orientado a la modelización cartográfica de densidades continuas, considerando la tasa de contagios de COVID-19. El área de estudio corresponde a los municipios de la cuenca del río Luján (Argentina). Los resultados cartográficos evidencian una marcada diferenciación espacial de la incidencia de los contagios en el interior de los municipios del área de estudio, y definen sectores de mayor dinamismo en la propagación espacio-temporal del virus.
¿Hacia un proceso de litoralización? Análisis geohistórico de los partidos de La Costa, Pinamar y Villa Gesell (Buenos Aires)
Authors: Maya Mario Alejandro
Published: January 2022

Los espacios litorales constituyen áreas de extraordinaria importancia para los seres humanos. Son espacios de una gran significación desde el punto de vista natural, social, político y económico. El presente trabajo realiza una aproximación a las características de ocupación del territorio costero en los Partidos de La Costa, Pinamar y Villa Gesell. Para ello, se utilizó la técnica de análisis geohistórico con el objetivo de analizar la evolución espacio/temporal del área objeto de estudio hacia el proceso de litoralización. La periodización elaborada permite reconocer las modificaciones vinculadas con la presión antrópica ejercida sobre el espacio litoral. La finalidad es comunicar la situación actual de los municipios para orientar acciones conducentes a un manejo integral de las áreas costeras como herramienta de gestión. Los resultados reflejan que el espacio analizado ha modificado, de manera determinante, su impronta fundacional y se hallan inmersos, en mayor o menor medida, en un proceso de litoralización. Originalmente fueron concebidas como un entorno escénico para una vida social alejada de la actividad cotidiana y adecuadas para realizar actividades recreativas y el disfrute de los paisajes. En cambio, la conjunción de actividades económicas, el aumento de la población y la expansión de emprendimientos urbanos cerrados han evolucionado sin una planificación sostenible. Si las autoridades municipales no toman medidas que propongan un manejo integrado de dicho espacio para una gestión planificada, la misma devendrá en una progresiva degradación del espacio litoral estudiado.
Una aproximación al manejo de cuencas hidrográficas desde el ordenamiento territorial en la Región Metropolitana de Buenos Aires
Authors: Baez Santiago , Cortizas Ludmila
Published: January 2022

En este trabajo se propone discutir sobre aquellas conceptualizaciones vinculadas al manejo o gestión de cuenca y al ordenamiento territorial, para luego indagar cómo estas miradas permean los instrumentos y organismos de ordenamiento territorial –actualmente vigentes– que tienen influencia en la Región Metropolitana de Buenos Aires (RMBA). Desde el punto de vista metodológico, se recurrió a la recopilación y análisis de aquellos instrumentos y organismos más representativos que tienen influencia en la RMBA, bibliografía específica, informes técnicos y sitios web oficiales. Los resultados obtenidos evidencian que aún continúan predominando las concepciones más tradicionales de ordenamiento territorial, manejo y gestión de cuencas, y, a su vez, la complejidad ambiental y territorial de la RMBA pareciera que no termina de ser correctamente abordada por tales instrumentos, dadas las múltiples jurisdicciones y el elevado grado de dispersión normativa existente.

Authors: Bonfanti Fernando Ariel , Sánchez Matías Emanuel
Published: January 2022

En las últimas décadas el calentamiento global ha intensificado incendios que destruyeron enormes áreas boscosas en diversas partes del mundo. La Argentina no ha quedado exenta de esta problemática y el Chaco mucho menos. Por tanto, el presente artículo intenta dar una mirada geográfica a la temática de los incendios forestales producidos en nueve departamentos del este de esta provincia durante el período comprendido entre los años 2015 y 2020. A través del análisis estadístico y la georreferenciación de información de diferentes fuentes, el trabajo tiene como objetivo identificar los focos de incendio que se han registrado en el área de estudio antes descrita y en ese lapso de tiempo, y caracterizar la actual gestión provincial en materia de riesgos de incendios. La producción de cartografía se realizó a partir de la utilización de Qgis. La región analizada sufrió en 2020 una gran cantidad de focos ígneos en áreas rurales que afectaron a poco más de 60 000 hectáreas, destruyendo pastizales, bosques nativos e implantados y, en consecuencia, deteriorando los suelos, la fauna silvestre, y perjudicando también la cobertura de rastrojos y a la hacienda.

Monster plants: the vegetal political ecology of Lacandonia schismatica
Authors: Durand Leticia , Sundberg Juanita
Published: January 2022

This article presents a story about a plant – Lacandonia schismatica – which subverted disciplinary traditions in botany and reconfigured its geopolitical orders of knowledge. To tell this story, we focus on Lacandonia's 'plantiness', Lesley Head and colleagues' (2012) concept to signify each kind of plant's unique biophysical characteristics, capacities, and potentialities, and through which they co-produce the world. We trace how L. schismatica intervened in, and (re)configured processes of knowledge production, environmental politics, and identity formation in the Lacandon Forest, Chiapas, Mexico, where it was found. Lacandonia's plantiness came into being through sudden macromutations; this unexpected but viable plant species participated in reviving an old debate in evolutionary biology: macroevolution versus gradualism. We also analyze how Lacandonia's plantiness compelled shifts in environmental politics in Chiapas and identity formation in Frontera Corozal, the Chol community where L. schismatica was first located. We conclude with a brief reflection on the implications of vegetal ethics for addressing contemporary environmental crises.
Reshaping Louisiana's coastal frontier: managed retreat as colonial decontextualization
Authors: Jessee Nathan
Published: January 2022

This article describes social encounters produced by climate adaptation policy experimentation focused on managed retreat—a concept increasingly used by academics and planning professionals to describe various kinds of relocation from areas exposed to environmental hazards. Building on scholarship that examines the political ecology of resettlement and adaptation, I draw on five years of ethnographic work conducted alongside Isle de Jean Charles Biloxi-Chitimacha-Choctaw Tribal leaders as their longstanding Tribal resettlement was transformed by government investment. I describe how Louisiana's Office of Community Development relied on Tribal planning to garner federal funds, used those funds to reduce the scope of the resettlement, and systematically erased the initial resettlement rationales and aims of Indigenous leaders. I liken the state's approach to Dina Gilio-Whitaker's notion of decontextualization as a colonial strategy, and argue that state efforts to transform the resettlement from what Tribal leaders viewed as "an act of cultural survival" to a scalable model for managed retreat policy threatens to reproduce a frontier dynamic whereby colonial and capitalist futures are once again rested upon the erasure of Indigenous peoples. State tools for decontextualization included published constructions of risk, community, and timelines; liberal planning conventions; and evocations of legal barriers. Ethnographic accounts of such processes can inform future resistance to eco-colonial schemes within climate adaptation.

Authors: González-Martell Andrea Daniela , Sánchez-Quintanilla Edison Enrique , García-Aguilar Nadia , Hernández-Contreras Tiaré , Cilia-López V. Gabriela
Published: January 2022

Indigenous communities in Mexico are vulnerable to food insecurity (FI) due to a series of factors that prevent them from having access to sufficient and nutritious food. Therefore, this population group has the highest chronic malnutrition in the country. Objective: This study describes the FI conditions of an indigenous community in the Potosina Huastec. Methodology: FI was measured with the Household Food Insecurity Access Component Scale (HFIAS). Results: There is food insecurity ranging from concern about food lack, food reduction, and hunger. The 95.57% of households with children under 18 years were in some state of food insecurity, with severe food insecurity dominating. Limitations: Was a cross-sectional study carried out in a community of the Potosina Huastec. However, it is the municipality with the highest degree of marginalization in the area, but the community chosen is the largest in the municipality. Nonetheless, the results can be considered representative of the area. Conclusions: The food security community depends on climatic, socioeconomic, demographic, geographic, cultural factors, food preference conditions, among others. In addressing food insecurity, it is necessary to consider all factors to have a real diagnosis of food insecurity conditions in rural and indigenous communities.

Dialektologia wobec zmian językowych na polskiej wsi. Jak mogłoby wyglądać nowe spojrzenie?
Authors: Rak Maciej
Published: January 2022

The article concerns the linguistic situation in the Polish village and the need for a new approach in dialectological research. In the 21st century, Polish dialectology becomes a de facto subdiscipline of sociolinguistics. The disintegration of the dialects means that there is a need for new descriptive research in the area that was part of Poland before 1945. In the western and northern territories (until 1945 belonged to Germany), it seems justified to conduct sociolinguistic research taking into account the communicative communities.

Zaprzeczone przymiotniki i imiesłowy przymiotnikowe w poematach romantycznych
Authors: Stachurski Edward
Published: January 2022

The article is a research attempt to show the participation of a group of negative adjectives and adjectival participles formed using prefixes nie- and bez- in 8 romantic poems representing the textual corps of Polish romantic poetry. The negatives with prefix nie- are nine times more numerous than negatives formed using prefix bez-. Almost each negative is in romantic poems less numerous than his not negative equivalent. The participation of negatives reach 1,45% of the vocabulary and 0,34% of the text of analyzed corps. From among 7 romantic poets C. Norwid uses negatives most willingly. Most frequently represented are negatives: niemy, nieruchomy, niewinny, nieznajomy and niezwykły. Negatives in romantic poems are used for semantic and stylistic purposes. Most often they serve the poets to specify the description of characters and things.
Prasa lokalna jako źródło do badań dialektologicznych (na przykładzie kieleckich „Przemian”)
Authors: Cygan Stanisław
Published: January 2022

The local press is used to a small extent for dialectological studies. In the article, I present a review and typology of press materials contained in the Kielce socio-cultural monthly „Przemiany” (Transformation, 1970–1989), which is a valuable source of language material, primarily for Polish dialectical lexicography, but also for the study of the language system of the Kielce dialects from the 1980s and 1990s. The sociolinguistic aspect is included in the description of dialects in the analyzed press texts. On the one hand, Kielce dialect materials broaden the number of printed sources for the issued Polish dialect dictionary, and on the other – they can be well used when developing a regional glossary.

Angka kematian maternal menjadi salah satu indikator yang dapat menggambarkan kesejahteraan masyarakat di suatu negara. Pada tahun 2019, di Provinsi Jawa Barat tercatat jumlah kematian ibu sebanyak 684 kasus atau 74,19 per 100.000 kelahiran hidup. Salah satu upaya untuk menurunkan angka kematian maternal di Provinsi Jawa Barat dapat dilakukan dengan memodelkan angka kematian maternal terhadap faktor yang mempengaruhinya sehingga nilai kematian maternal dapat diestimasi. Pada penelitian ini, angka kematian maternal di Provinsi Jawa Barat diestimasi dengan parameter model regresi nonparametrik B-Spline menggunakan pendekatan metode Ordinary Least Square (OLS). Pemilihan regresi nonparametrik B-Spline dikarenakan hasil plotting setiap variabel respon terhadap variabel prediktor tidak menunjukkan pola tertentu, selain itu model regresi B-Spline memiliki fleksibilitas yang tinggi. Model B-Spline terbaik bergantung pada penentuan titik knot optimal yaitu dengan nilai Generalized Cross Validation (GCV) minimum. Setelah dilakukan analisis angka kematian maternal berdasarkan regresi nonparametrik B-Spline diperoleh suatu model terbaik pada saat orde dua dan banyaknya titik knot untuk X1 adalah dua, X2 adalah satu, X3 adalah tiga, dan X4 adalah tiga dengan nilai GCV sebesar 352,3002, sementara nilai koefisien determinasi yang diperoleh sebesar 0, 8443.

Authors: Sroyer Alvian M. , Mandowen Samuel A. , Reba Felix
Published: January 2022

Malaria adalah penyakit yang disebabkan oleh parasite bernama Plasmodium. Tercatat keseluruhan kasus malaria yang terjadi di Indonesia pada tahun 2019 adalah sebanyak 250.644 kasus. Dan kasus malaria tertinggi terjadi di provinsi Papua, yaitu sebesar 86% atau sebanyak 216.380 kasus. Di Provinsi Papua, penyakit malaria dialami oleh semua usia dan bulan-bulan terjadi peningkatan pasien penderita malaria juga sangat bervariasi. Hal ini mengakibatkan dinas Kesehatan mengalami kesulitan dalam mengelompokan jenis malaria berdasarkan usia pasien dan bulan-bulan kejadian. Sebenarnya sudah ada penelitian yang menjelaskan pengelompokan jenis-jenis malaria, namun belum dijelaskan secara terperinci masing-masing kelompok malaria seperti Malaria Tropika, Malaria Tertiana, Malaria Quartana, Malaria Ovale. Tujuan dari penelitian ini adalah, melakukan analisis cluster terhadap beberapa jenis malaria, usia dan bulan kejadian. Metode cluster yang digunakan dalam penelitian ini adalah metode Single Linkage dan K-Means. Selanjutnya kedua metode akan di evalusi menggunakan standar deviasi. Metode terbaik yang dapat digunakan untuk analisis cluster adalah metode yang memiliki nilai standar deviasi lebih kecil. Data yang digunakan dalam penelitian ini adalah data sekunder yang diperoleh dari Dinas Kesehatan Provinsi Papua. Hasil penelitian menunjukan bahwa, metode Single Linkage lebih akurat dibandingkan dengan K-Means. Dimana dari 50 pasien terdapat 47 pasien lebih dominan terkena penyakit malaria tertiana yaitu pada rentang usia remaja dan dewasa pada bulan juni. Sehingga diharapkan pemerintah Provinsi Papua dapat memberikan sosialisasi kepada masyarakat, khususnya mereka yang pada rentang usia remaja dan dewasa. Karena hampir 94% penyakit malaria tertiana di derita oleh mereka yang berusia remaja dan dewasa.

Published: January 2022

This paper empirically identifies the hidden periodicities in the time series of monthly food inflation of Turkey with its subgroups for the periods from January, 2004 to June, 2020. Periodicity is the hidden cycles of the time series which is beyond the seasonality. In order to deal with this hidden cycles periodogram based time series analysis is used. Also, future inflation ratios are forecasted by Harmonic regression. The results of this study reveal that food inflation of Turkey has cycles of approximately 2 years which is mostly derived by food and non-alcoholic beverage inflation.
Correlations of gas, dust and young stellar populations in the spiral galaxy NGC 7331
Authors: TOPAL Selçuk
Published: January 2022

Molecular clouds (MCs) in galaxies are complex places with many phases. It is, therefore, essential to study the physics and kinematics of the MCs using multiple emission lines. We probe the physics of the molecular gas and dust in the nearby spiral galaxy NGC 7331 using multiple emission lines, i.e. carbon monoxide (CO), 24μm and far-ultraviolet (FUV) data. 14 positions were targeted across the gaseous disc of NGC 7331. We found that CO intensities, gas mass, gas surface density, and 24μm-to-FUV flux ratio (i.e. the extinction) increase up to about 40 arcsec from the centre and then start to decrease. There is a positive correlation between most of the pair of parameters studied (except FUV flux density). The beam-averaged physical parameters on the eastern side of the disc show higher median values than those on the western side. Our results indicate that the star formation activity, stellar populations and overall physical properties of the ISM are different on either side of the disc. Our study provides notable insights into the complex nature of the interstellar medium (ISM) in galaxies and has the potential to provoke future higher-resolution studies yet to come.

Bu çalışmada 5, 10 ve 15 cm yüksekliklerdeki Hız Kesici Tümseklerin (HKT) toplu yolcu taşıma faaliyetlerinde sıklıkla kullanılan minibüs, midibüs ve otobüs sınıfındaki taşıtlar üzerinde hızı azaltma konusundaki performansları değerlendirilmiştir. HKT’lerin taşıt hızlarını azaltma konusundaki performansları, kamera görüntüleri aracılığıyla taşıtların mesafe ortalamalı hız değerleri okunarak araştırılmıştır. Öncelikle, HKT’lerin sürücülerin hızlarını azaltma konusunda etkilemediği bir mesafede taşıt hızları (Etkilenmemiş Hız, EH) belirlenmiştir. Hız azaltma performanslarını belirlemek amacıyla her bir HKT’den geçen taşıtların -60 m, -40 m, -20 m, 0 m (üzerinden geçişte), +20 m, +40 m ve +60 m’lerdeki hızları belirlenmiştir. Tüm hız ölçümleri Serbest Akım ve Doygun Akım olmak üzere iki faklı trafik akım rejiminde ayrı ayrı yapılmıştır. Hızlar ve EH’ya göre her bir noktadaki Yavaşlatma Oranı (YaO) değerleri grafikler yardımıyla görselleştirilerek sonuçlar karşılaştırılmıştır. Ayrıca, değerlendirilen her bir HKT için hız ölçülen farklı ölçüm noktaları arasında ve her bir hız ölçüm noktası için taşıt türleri arasında istatistik benzerlikler araştırılmıştır. Yalnızca sınırlı sayıda araştırmanın bulunduğu bu konuda literatüre katkı sağlanmıştır.

Authors: YALÇIN KUZU Serpil
Published: January 2022

Dielektronlar olarak adlandırılan elektron (e-) pozitron (e+) çiftleri, evrenin oluşumunu anlamak için yapılan yüksek enerjili parçacık çarpışma deneylerinin çeşitli süreçlerinde üretilen elektromanyetik sinyallerdir. Bu parçacık çiftleri, güçlü kuvvet etkileşimi yapmamaları sebebiyle bulundukları ortamın özelliklerinden etkilenmezler ve böylece çeşitli üretim mekanizmaları ile ilgili önemli bilgi sağlarlar. Dielektronları ölçmek için yüksek saflıkta çift sinyalleri gereklidir. Bu sinyalleri, kendisinden çok daha büyük olan arka plan (fon) kaynaklarından (e+e+, e-e-) ayırt etmek için karmaşık analiz teknikleri gereklidir. Geleneksel parçacık analiz yöntemleri ile dielektron çiftleri yüksek sistematik belirsizlikler ile üretilir. Son yıllarda çeşitli alanlardaki yapay zeka (AI) uygulamaları, insan çabalarının hızını, doğruluğunu ve verimliliğini artırmak için önem kazanmaktadır. Bu çalışmada dielektron analizinde yapay zeka tabanlı makine öğrenmesi yaklaşımı kullanılmıştır. Çalışmada rastgele orman (RO) sınıflandırma yöntemi Büyük Hadron Çarpıştırıcısı 2010 yılı verisinde bulunan dielektronların elde edilmesine uygulanmıştır. Yapılan çalışmada %90.9 duyarlılık ve %92.0 kesinlik ile RO metodu uygulanmış dielektron analizleri %98.2 başarı göstermiştir.
New fixed-disc results via bilateral type contractions on S-metric spaces
Authors: TAŞ Nihal
Published: January 2022

There are some examples of self-mappings which does not satisfy the Banach contractive condition and have a unique fixed point or more than one fixed point. In this case, metric fixed-point theory has been extensively generalized using some techniques. One of these techniques is to generalize the used contractive conditions such as the Jaggi type contractive condition, the Dass-Gupta type contractive condition etc. Another technique is to generalize the used metric spaces such as a b-metric space, an S-metric space etc. The last technique is to investigate geometric properties of the fixed-point set of a given self-mapping such as fixed circle, fixed disc etc. For this purpose, “fixed-circle problem” has been studied with various techniques as a geometrical generalization of the metric fixed-point theory. This problem was also considered as “fixed-figure problem”. Some solutions to these recent problems were obtained using different contractions both a metric space and a generalized metric space. The main purpose of this paper is to prove some fixed-disc theorems on an S-metric space. To do this, we modify the known contractive conditions. Also, the obtained new theorems are supported by some illustrative examples.

Published: January 2022

El objetivo del presente estudio es determinar el impacto de las variables institucionales sobre la degradación ambiental en dieciséis países de América Latina, medida por la emisión de CO2 y el cambio en la Huella Ecológica (HE), desde el enfoque de la Curva Medioambiental de Kuznets (EKC). Se utiliza datos de panel de los países durante el periodo 2002-2014. Los resultados confirman la hipótesis EKC cuando usamos las emisiones de CO2, y para el caso de la HE se verifica únicamente cuando las variables institucionales se introducen como un indicador sintético. Según ambos modelos, estamos lejos del punto de inflexión.
