Published: November 2021

Las políticas educativas planteadas en Guatemala, sus características e ideales, se establecen como como un parámetro de referencia para los docentes, a partir de la importancia de conocer y establecer cuáles son las estrategias educativas actuales, al paso de los años y de diversas reformas a la educación los efectos no has sido los esperados, se ha establecido a los docentes como elementos claves en las transformaciones pedagógicas por razones que no son objetivas, es pues la labor docente en simultaneo la problemática mayor y la solución más viable en el ideal de la mejora de la educación (Villafuerte, 2020).

 

Los cimientos sobre los que descansan los sistemas escolares se enfocan en que la enseñanza tradicional, en donde el docente dicta una catedra y el estudiante escucha y asimila lo que pueda, es por ello que el rol de los educadores es preponderante, pues a partir de su disponibilidad por adquirir destrezas y aptitudes demandadas por los diferentes contextos, en conjunto con la comunidad educativa, como una serie de engranajes movidos por un eje central, en este sentido la responsabilidad social de los formadores en el marco del cambio de los sistemas educativos, es necesaria e indispensable.

Astrometric Mass Ratios of 248 Long-period Binary Stars Resolved in Hipparcos and Gaia EDR3
Authors: Makarov Valeri V. , Fabricius Claus
Published: November 2021

Using the absolute astrometric positions and proper motions for common stars in the Hipparcos and Gaia catalogs separated by 24.75 yr in the mean epoch, we compute mass ratios for long-period, resolved binary systems without any astrophysical assumptions or dependencies, except the presence of inner binary subsystems that may perturb the observed mean proper motions. The mean epoch positions of binary companions from the Hipparcos Double and Multiple System Annex are used as the first epoch. The mean positions and proper motions of carefully cross-matched counterparts in Gaia EDR3 comprise the second epoch data. Selecting only results with sufficiently high signal-to-noise ratio and discarding numerous optical pairs, we construct a catalog of 248 binary systems, which is published online. Several cases with unusual properties or results are also discussed.
Binary Black Hole Formation with Detailed Modeling: Stable Mass Transfer Leads to Lower Merger Rates
Authors: Gallegos-Garcia Monica , Berry Christopher P L , Marchant Pablo , Kalogera Vicky
Published: November 2021

Rapid binary population synthesis codes are often used to investigate the evolution of compact-object binaries. They typically rely on analytical fits of single-star evolutionary tracks and parameterized models for interactive phases of evolution (e.g., mass transfer on a thermal timescale, determination of dynamical instability, and common envelope) that are crucial to predict the fate of binaries. These processes can be more carefully implemented in stellar structure and evolution codes such as MESA. To assess the impact of such improvements, we compare binary black hole mergers as predicted in models with the rapid binary population synthesis code COSMIC to models ran with MESA simulations through mass transfer and common-envelope treatment. We find that results significantly differ in terms of formation paths, the orbital periods and mass ratios of merging binary black holes, and consequently merger rates. While common-envelope evolution is the dominant formation channel in COSMIC, stable mass transfer dominates in our MESA models. Depending upon the black hole donor mass, and mass-transfer and common-envelope physics, at subsolar metallicity, COSMIC overproduces the number of binary black hole mergers by factors of 2–35 with a significant fraction of them having merger times orders of magnitude shorter than the binary black holes formed when using detailed MESA models. Therefore we find that some binary black hole merger rate predictions from rapid population syntheses of isolated binaries may be overestimated by factors of ∼ 5–500. We conclude that the interpretation of gravitational-wave observations requires the use of detailed treatment of these interactive binary phases.

Depression in magnetic field strength with a scale below one proton gyroradius is referred to as a kinetic-size magnetic hole (KSMH). KSMHs are frequently observed near Earth’s space environments and are thought to play an important role in electron energization and energy dissipation in space plasmas. Recently, KSMHs have been evidenced in the Venusian magnetosheath. However, observations of KSMHs in other planetary environments are still lacking. In this study, we present the in situ detection of KSMHs in the Martian magnetosheath using Mars Atmosphere and Volatile EvolutioN (MAVEN) for the first time. The distribution of KSMHs is asymmetry in the southern–northern hemisphere and no obvious asymmetry in the dawn–dusk hemisphere. The observed KSMHs are accompanied by increases in the electron fluxes in the perpendicular direction, indicating the cues of trapped electrons and the formation of electron vortices inside KSMHs. These features are similar to the observations in the Earth’s magnetosheath and magnetotail plasma sheet and the Venusian magnetosheath. This implies that KSMHs are a universal magnetic structure in space.
On the Origin of Gamma-Ray Flares from Bright Fermi Blazars
Authors: Paliya Vaidehi S. , Böttcher M. , Gurwell Mark , Stalin C. S.
Published: November 2021

The origin of γ-ray flares observed from blazars is one of the major mysteries in jet physics. We have attempted to address this problem following a novel spectral energy distribution (SED) fitting technique that explored the flaring patterns identified in the broadband SEDs of two γ-ray bright blazars, 3C 279 (z = 0.54) and 3C 454.3 (z = 0.86), using near-simultaneous radio-to-γ-ray observations. For both sources, the γ-ray flux strongly correlates with the separation of the SED peaks and the Compton dominance. We propose that spectral hardening of the radiating electron population and/or enhancement of the Doppler factor can naturally explain these observations. In both cases, magnetic reconnection may play a pivotal role in powering the luminous γ-ray flares.

Thysanoptera is amongst the most predominant orders of insects in different ecological zones with worldwide distribution. Due to their small size, there is a large gap in their distribution and host range data. To the best of our knowledge, there is no investigation on the thrips distribution and their host range in Xishuangbanna. Currently, a total of 566 species in 155 genera are listed in China, of which 313 species represent Terebrantia.

In this study, a list of 116 species representing 55 genera within the families Aeolothripidae and Thripidae is provided. Two of these, Dichromomothrips nakahari Moud, 1976 (subfamily Thripinae) and Phibalothrips rugosus Kudo, 1979 (subfamily Panchaetothripinae) are recorded for the first time in China. Thrips species with their host ranges, habits and habitats are provided. Our study aims to contribute to the global biodiversity distribution data-gap of Thysanoptera for conservation purposes, as well as pest species targetting Integrated Pest Management tactics.
Les deux Casse-noisettes ou le détour par l’enfance
Authors: Labouret Mireille
Published: November 2021

Balzac met en scène dans Le Cousin Pons des personnages vieillissants dans un univers promis à la mort. Or, les deux « casse-noisettes », Pons et Schmucke, sont présentés comme des enfants : Pons, « vieillard de naissance », concentre en lui les défauts et les goûts attribués à la petite enfance tandis que Schmucke incarne la naïveté et l’innocence de cet âge. Ce retour à l’enfance s’accompagne pour les deux musiciens d’un détour par les formes artistiques du conte et de la féérie, propices au déploiement d’un imaginaire propre à l’enfance, les figures de l’ogresse et de la marâtre se superposant au visage de la mère protectrice. Toutefois, c’est le sourire de l’enfance, émanant de la petite Topinard, qui éclaire le dénouement bien sombre du récit et suggère qu’il est d’autres liens que ceux de la famille bourgeoise et d’autres valeurs que celles prônées par le clan Camusot pour illustrer l’adage res duplex de la dédicace des Parents pauvres au prince de Teano.
Petites choses et petites gens dans Le Cousin Pons
Authors: Conrad Thomas
Published: November 2021

On considère ici Le Cousin Pons comme un renouvellement de l’univers balzacien, autour d’un romanesque du « petit ». Un « rapetissement » (social, spatial, psychologique) de l’univers balzacien se produit dans Le Cousin Pons , avec un déplacement vers les « petites gens » (petits bourgeois et classes populaires), qui donne un rôle nouveau aux « petites choses », même par rapport à l’esthétique réaliste du détail des années 1830-1840. La collection de Pons en est l’emblème. On remet ainsi en perspective les interprétations dominantes du roman, marxistes (Barbéris) ou déconstructionnistes (Schuerewegen, de Biasi). Le roman n’est pas structuré par l’opposition entre classes, ni par une indifférenciation ironique, mais par un réseau complexe de micropouvoirs (Foucault) et de dynamiques « moléculaires » (Deleuze) dont le sujet n’est pas la bourgeoisie, mais les petites gens eux-mêmes. Le roman étudie comment l’argent s’infiltre dans la texture fine des rapports sociaux pour les redéfinir.

Published: November 2021

Autoimmune blistering skin disorders are rare. According to direct immunofluorescence studies, three categories are described: pemphigus group, pemphigoid group and dermatitis herpetiformis. Among these diseases, bullous pemphigoid is the most common. Patients with typical bullous pemphigoid disease are usually elderly and have many comorbidities. Considering that topical and systemic corticosteroids are the first choice therapy, these patients also have increased morbidity and risk of death. The main characteristic of bullous pemphigoid as an acquired autoimmune blistering disease is the formation of autoantibodies against hemidesmosomal antigens BP180 and BP230. Although IgG autoantibodies predominate within the plasma and skin of BP patients, some features of the disease cannot be explained solely by IgG-mediated mechanisms. Epitope spreading phenomena, immunoglobulin class switch and the relevance of IgM and IgE autoantibodies are discussed in this article.

The Urban growth in Trikomo (Yeni İskele) region in Cyprus has dramatically increased recently. The unorganized and uncontrolled development process has started to consume land resources; loss of landcover, valuable agricultural lands, and change of wetlands of stream beds or ponds occurred. In addition, partial and fragmented housing development projects bring only housing and second housing to the coastal region. As a result, environmental and economic problems occurred in sustainable urban growth (SUG) in the Trikomo (Yeni İskele) region. Due to the lack of planning instruments in Trikomo, urban expansion policies and alternatives have been ignored. In this regard, this research tries to investigate spatial SUG and expansion alternatives by using Multi-Criteria Evaluation (MCE) and fuzzy logic within geographical information systems (GIS). Compact growth, environmental protection, and equal accessibility to local services were used for multi-criteria analysis to construct spatial SUG problems. Then they were converted to spatial layers within the (GIS) environment. Results show that; 6 percent of the study area is in a shallow suitability zone. Forty-four percent of it has very low and low suitability for SUG. Also, 41 percent of the area is suitable. Only 12 percent of the area has high and very high suitability values. These findings showed that approximately 118 square kilometers (56 percent) of the city is within the same level appropriate for urban development.
A justiça brasileira sob medida : A pandemia no Brasil entre direitos e privilégios

Published: November 2021

Partindo da afirmação de que a sociedade brasileira se estrutura de forma hierarquizada, reproduzindo um ethos aristocrático em contraposição a uma ordem republicana, podemos reconhecer que, no plano jurídico, a desigualdade se opera em dois níveis : no aspecto normativo – por meio da elaboração das leis – e na administração dos conflitos, quando da aplicação das leis, especialmente pelo Judiciário. Nesse texto pretendemos problematizar o modo como as instituições judiciárias no Brasil internalizam e (re)produzem desigualdades jurídicas – o que se tornou mais evidente com a pandemia da Covid-19 e suas consequências para a esfera de direitos dos brasileiros. Para tanto, pretendemos descrever três categorias de casos (os casos de auxílio-saúde ; casos de “fura-fila” da vacinação contra a Covid-19 ; e os casos de pedidos de liberdade de réus presos em razão da pandemia da Covid-19), que ajudam a revelar essa chave da desigualdade.
AUTOMATED POLYP DETECTION IN COLONOSCOPY VIDEOS USING IMAGE ENHANCEMENT AND SALIENCY DETECTION ALGORITHM
Authors: Nisha J. S. , Gopi V. P. , Palanisamy P.
Published: November 2021

Colonoscopy has proven to be an active diagnostic tool that examines the lower half of the digestive system’s anomalies. This paper confers a Computer-Aided Detection (CAD) method for polyps from colonoscopy images that helps to diagnose the early stage of Colorectal Cancer (CRC). The proposed method consists primarily of image enhancement, followed by the creation of a saliency map, feature extraction using the Histogram of Oriented-Gradients (HOG) feature extractor, and classification using the Support Vector Machine (SVM). We present an efficient image enhancement algorithm for highlighting clinically significant features in colonoscopy images. The proposed enhancement approach can improve the overall contrast and brightness by minimizing the effects of inconsistent illumination conditions. Detailed experiments have been conducted using the publicly available colonoscopy databases CVC ClinicDB, CVC ColonDB and the ETIS Larib. The performance measures are found to be in terms of precision (91.69%), recall (81.53%), F1-score (86.31%) and F2-score (89.45%) for the CVC ColonDB database and precision (90.29%), recall (61.73%), F1-score (73.32%) and F2-score (82.64%) for the ETIS Larib database. Comparison with the futuristic method shows that the proposed approach surpasses the existing one in terms of precision, F1-score, and F2-score. The proposed enhancement with saliency-based selection significantly reduced the number of search windows, resulting in an efficient polyp detection algorithm.

Authors: Davlin-Pater Christina
Published: November 2021

Context

The educational escape room is an innovative teaching strategy, and the use of this technique is gaining popularity in some health care disciplines. It is believed to promote acquisition of knowledge and skills, increase motivation, and encourage engagement, critical thinking, collaboration, and problem-solving.

Objective

To describe the use of an innovative educational escape room in a master's-level athletic training course and to examine learning effectiveness and students' perceptions.

Design

Quasi-experimental.

Setting

A Commission on Accreditation of Athletic Training Education–accredited master's-level athletic training program.

Patients or Other Participants

A convenience sample of 14 students enrolled in a master's-level professional athletic training program participated.

Intervention(s)

Educational escape room.

Main Outcome Measures(s)

A paired-samples t test was used to determine differences between preactivity and postactivity knowledge-assessment scores. Measures of central tendency were used for survey questions related to student perceptions of the activity. Student perceptions were assessed after the intervention.

Results

All participants completed the preactivity and postactivity knowledge assessments. The difference in scores was found to be statistically significant (t13 = −4.502, P = .001), with a large effect size (Cohen d = 1.32). Participants thought the escape room was an effective way to improve their knowledge of course materials (mean ± SD = 5.0 ± 0.0) and encouraged them to apply course material in a new way (mean ± SD = 4.9 ± 0.27). Participants reported that they had fun (mean ± SD = 5.0 ± 0.0) and felt that the activity was immersive (mean ± SD = 5.0 ± 0.00). Qualitative elements from the postactivity survey corroborated the data.

Conclusions

The education escape room described in this study promoted learning while providing a fun and engaging learning experience with positive perceived value.

Point-of-care (POC) tests to detect SARS-CoV-2 antibodies offer quick assessment of serostatus after natural infection or vaccination. We compared the field performance of the BioMedomics COVID-19 IgM/IgG Rapid Antibody Test against an ELISA in 303 participants enrolled in a SARS-CoV-2 household cohort study. The rapid antibody test was easily implemented with consistent interpretation across 14 users in a variety of field settings. Compared with ELISA, detection of seroconversion lagged by 5 to 10 days. However, it retained a sensitivity of 90% (160/177, 95% confidence interval [CI] 85–94%) and specificity of 100% (43/43, 95% CI 92–100%) for those tested 3 to 5 weeks after symptom onset. Sensitivity was diminished among those with asymptomatic infection (74% [14/19], 95% CI 49–91%) and early in infection (45% [29/64], 95% CI 33–58%). When used appropriately, rapid antibody tests offer a convenient way to detect symptomatic infections during convalescence.

Published: November 2021

This study investigated the relationship between the levels of fungicide pollution and the abundance and diversity of macroinvertebrate fauna in three river systems: Aponmu, Oruwo, and Owena in south-western Nigeria, which are in close proximity to cocoa plantations. For each river, three sites were selected for the collection of water and sediment samples from April to July, 2018. Prior to sample collection, the physicochemical parameters (electrical conductivity, total dissolved solutes, pH, temperature, and dissolved oxygen) were determined. Also, aquatic macroinvertebrates were collected, and were identified to generic level, where possible. The levels of copper and sulphate in the samples were determined following standard procedures. The range of mean values for the physicochemical parameters were: 0.07-0.20 mS/cm, 60.00 – 154.00 ppm, 24.60 – 28.13 °C, 6.97 – 7.43, and 0.87 – 2.87 mg/L for electrical conductivity, total dissolved solutes, temperature, pH, and dissolved oxygen respectively. The range of mean values for copper and sulphate in sediment samples were 30.58 – 56.63 mg/Kg and 787.12 – 978.33 mg/Kg respectively while those for the water samples were 2.86 – 6.93 mg/L and 476.6 – 685.58 mg/L respectively. A total of nineteen (19) macroinvertebrate genera comprising Insecta (14), Gastropoda (3), Crustacea (1), and Bivalvia (1) were recorded. Taxa richness and species diversity were higher in river Owena in comparison to rivers Aponmu and Oruwo. The high abundance of the taxa: Potamididae, Gerridae, Notonectidae, Libellulidae, and Platycnemididae in the sampled rivers notwithstanding the pollution levels is an indication that these taxa are capable of thriving in polluted aquatic systems.

Published: November 2021

Antibiotics resistance is a rapidly emerging issue through the misuse of antibiotics to treat human and animalrelated infections. The use of beta-lactams has increased considerably since its discovery so also resistant genes leading to Extended-Spectrum Beta-Lactamases (ESBL) mediated by the presence of blaCTX-M , blaTEM and blaSHV genes present in most Gram-negative bacteria. This study aimed to detect the widespread distribution of ESBL genes from fomites, healthcare workers, and patients suffering from urinary tract infection in two hospitals in  Lagos state, Nigeria. A total of 150 swab samples were collected from fomites, health care workers, and cathetersof patients suffering from urinary tract infection (UTI). Antibiotics susceptibility test was performed by Kirby- Bauer technique according to CLSI guidelines. Organisms that tested positive phenotypically for ESBL were subjected to PCR for molecular analysis. ESBL prevalence rate of 21.8% and a carbapenemase-resistance rate of 16.7% were recorded. The ESBL producing isolates showed the highest resistance to ceftriaxone (82.4%) and the least resistance to tigecycline (5.9%). The existence of blaCTX-M and blaTEM was detected in 76.5% and 17.6% of the isolates respectively, while bla encoding gene was not detected in this study. The distribution of blaSHV genes detected in this study is of great concern which necessitates strict control measures in the usage of antibiotics especially the third-generation cephalosporin. In summary, the presence and distribution of ESBL encoding genes within two hospitals in Lagos were tested and the highest occurrence was recorded in blaCTX-M gene  reducing and limiting the available treatment option for infections.

Published: November 2021

Lentinus squarrosulus is a popular mushroom in Nigeria used for traditional medicine apart from food. The identification of those high-quality fungal species is not only necessary but has great economic significance as it will allow product distributors to verify the material they are selling. Hence, this study investigated the morphological and molecular relationship among L. squarrosulus samples from different locations in Ibadan. Ten samples of L. squarrosulus were collected from nine different natural habitats in Ibadan, Oyo State, Nigeria, from which pure cultures were prepared. Isolation of DNA was done from fruiting bodies of fresh samples evaluated. Ten primers were designed from ITS sequences of the Family Agariceae and used for the study. The ten mushrooms evaluated in the study showed diverse morphological features such as colour of cap and pileus, size of stipe and pileus. A total of 50 amplicons were generated of which 31 bands (62%) were polymorphic. The RAPD variety-specific products were generated in some of the genotypes evaluated which can serve as unique identifiers. The study showed mean values for marker gene diversity of 0.27, Polymorphism Information Content (PIC) of 0.25 and 63.81% polymorphism. Both morphological and molecular analyses revealed two clustered groups. Number and types of samples in each group were not the same in both studies. The presence of unique band pattern among sampled fungi evaluated showed the discriminating power of the primer Ast-F in the study.

Quarrying activities are explored to extract a variety of materials deposited underneath the earth surface. These activities however can potentially impact negatively on soil quality and cause elemental pollution. This study assessed soil quality and distribution of metals in soils around four quarrying sites (PAPA, S&D, TCity and Mile 8) within Abeokuta, Ogun State, Nigeria. Thirty six topsoil samples were collected at distances from quarry gates in September 2019 and analyzed using standard methods. Soil quality and metal concentrations were compared with reference and standards and the degrees of soil contamination assessed using relevant indices. Soil quality reduced with distance from the quarry gates. Similarly, metal concentrations had strong and significant (P=0.05) negative relationships with distance and were higher in soil samples compared to the reference. Moderate contaminations for all metals were observed in soils collected close to the quarry gates soils from the results of the contamination factor index (Cf).  However, the results of ecological risk index (Ei) showed that the metal  loads in soils currently do not pose any ecological risk.

This paper 1 analyzed and compared the main macroeconomic indicators of Xinjiang Uygur Autonomous Region (XUAR) of China and the other provinces in China, by using the macroeconomic data of China and 12 western provinces from 1999 to 2011 and considering the indicators of average developing level and economic development. Results from this study shows that the main problems existing in the process of economic development include several aspects in XUAR, such as lacking scale of fixed and foreign investment, and existed big gap of people's income between XUAR and the whole country and the other western provinces, and also, the industrial structure is not reasonable. Therefore, XUAR should fully use the golden opportunity for a new round of western development strategy including national policy on counterpart support, and makes effort in improving investment environment and expanding the ways to attract foreign investment as well as increasing the resident’s income to reduce the gap in income. Currently, the most urgent task of XUAR is to adjust local industrial structure and speed up the social economy so as to catch up with the average developing level of China.

Although participants indicated that their frequency and skills of using the electronic devices or applications had generally increased or improved after the training, the increment was not statistically significant (). This indicated that while the participants, to some extent, benefited from the online training provided, there has not been a significant impact on them
A Study on the Teaching Method for Academic Writing through Interactive Feedback
Authors: Park Sang-eun , Ahn Seohyun
Published: November 2021

Interactive feedback refers not to the unidirectional feedback given by a professor, but rather to responsive feedback is provided as response the student’s self statement on their own writing, regarding his or her their intentions as an author and their writing process. It allows students to accept feedback as conversation and communication with readers within the academic community, rather than as a modification demand or justification of evaluation from the professor. Students can experience feedback request and constructive application of the feedback in their writing as a useful writing strategy. Professors also can provide effective and efficient writing guidance and advice by identifying their students’ writing intentions and concerns in advance. This study examined the theory and overseas examples of practiced interactive feedback, constructed post-writing activities and feedback process that can be implemented in class, and then demonstrated them in writing courses of university. As a result, this study confirmed that students experience the writing process in a more communicative manner through interactive feedback.
Korean University Students' Usage, Awareness and Attitudes Toward ELF
Authors: Shin Hyojung
Published: November 2021

Based on a survey conducted among 77 Korean university students, this article examined their usage and awareness of ELF (English as a Lingua Franca), and observed if problems which previous researches have claimed appeared among them. By analyzing data gathered via 2 simple questions and 4 descriptive questions, this study found that the respondents appreciated English as a basic medium for global communication. The respondents also reported various domestic and foreign situations in which they used English to communicate with different interlocutors who spoke different native languages. However, critical issues, such as ownership of English, idealized attitudes toward Standard English, and bias against the varieties of English spoken, all of which have been reported in several empirical researches, were also detected. As globalization extends throughout all areas of our life, and as L2 speakers excel L1 speakers in number as a result, this article calls for more effort to discuss ELF issues in general English education for university students. It also calls for the development of new pedagogical practices. The findings of this study could provide for a meaningful start in that it looked into the real life situations of the students.

The purpose of this study is to analyze the English learning experience of college students using Colaizzi's method, which is one of the qualitative research methods, using self-coaching technology as a tool to improve self-directed learning ability. In-depth interview were conducted to collect data, and 9 significant statements, 4 theme clusters, and 2 categories were derived.
The results are as follows. First, it showed that the participants clearly set the reasons and goals for learning English. Second, it was confirmed that they had time to return to the positive motivation they experienced in the past and strengthened their will to overcome difficulties caused by self-coaching. Third, it was reported that they had a valuable experience of asking the questions presented for the first time, and they recollected the feelings of when they happily learned English, thereby gaining new vitality for learning English. Finally, it also showed that they experienced risk factors such as a desire to procrastinate, a desire to give up, and a rush to complete a task due to difficulty in self-control, which could lead to poor learning.
Based on these results, it was suggested that self-coaching contributed to the improvement of learning English, the importance of questions, necessary factors when expanding to regular classes, and the expansion of coaching research.

The selected research papers were examined for their research trends by the year, type, and research topic. The progress by the year and type show that there has been an ongoing stream of research regarding culture education in Korean for academic purposes since 2006, and that since 2018 the presentations of dissertations has increased. The analysis results by the research topic were examined according to “current state,” “curriculum,” “educational content,” “teaching plans,” “educational materials,” and “cultural factors”. This study found that there was more active research involving plans for cultural instructions than other topic areas across all the dissertations and papers published in journals. Futhermore, the proportion of research papers on literature was high. Based on these analysis results, this study proposed certain directions that instructors should take for culture education research that pertains to culture education in Korean for academic purposes.
YENİ TÜRK ŞİİRİNİ BESLEYEN BİR KAYNAK: MEVLÂNA
Authors: NAS Halef
Published: November 2021

Cumhuriyet dönemi Türk edebiyatı tarihinde Mevlâna’nın değerini idrak eden şairler az değildir. Hikayeci, romancı, tiyatrocu, denemeciler de bunlara eklenince sayı daha da çoğalacaktır. Bu yönüyle Cumhuriyetin kuruluşundan sonra gelişen Türk edebiyatında Mevlâna’nın yeri, edebi türler bağlamında henüz araştırılmış değildir. Konu şu hâlde bakir bir saha gibi durmakta ve yüksek lisans, doktora seviyesinde ilgilenecek araştırmacıları beklemektedir. Bu araştırmalar içinde öne çıkacak ilk kavram “gelenek” olacaktır. Cumhuriyet dönemi Türk şiirinin ilk yarısında ağırlıklı olarak ifadesini bulan inkılap şiiri, inkılapçı şiir ve gelenek şiirine bakıldığında Mevlâna ve Mesnevi’sini kaynak olarak gören şairlerin üçüncü grupta ağırlıklı olarak kümelendiği tahmin edilebilir. Bu dönemde yetişen kimi büyük şairlerin teorik yazılarında şiirin ayırt edici bir vasfı “süreklilik” olmuştur. “Süreklilik” geçmiş, hal ve geleceği birbirine bağlayan geleneğin şiirinde ifadesini bulur. Geleneğe yaslanan bir şiir dilinin geçmişin kaynaklarını ihmal etmeyeceği de aşikardır. Bu yazı şiirde sürekliliğin bir örneği olarak, vefatı üzerinden asırlar geçmesine rağmen Mevlana’nın günümüz şiirini bir kaynak olarak nasıl beslediğine odaklanmaktadır.
Durağan'ın (Sinop) Jeoturizm Açısından Değerlendirilmesi
Authors: BAĞCI Harun Reşit , KARADURAK Sevcan
Published: November 2021

Bu çalışmada, Durağan’da bulunan Jeomorfosit olma potansiyeline sahip yer şekilleri araştırılmıştır. Batı Karadeniz Bölümü’nde yer alan Durağan, Sinop’un kıyı ardı ilçelerinden biridir. Tektonizma, flüvyal süreçler ve litolojisine bağlı olarak jeomorfolojik açıdan ilgi çekici yer şekillerine sahiptir. Çalışma kapsamında; Durağan’da jeomorfosit olabilecek yer şekillerinin tespiti, tanıtılması ve jeomorfoturizm potansiyellerinin nicel olarak belirlenmesi amaçlanmıştır. Bu amaçla; arazi çalışmalarıyla yer şekilleri tespit edilerek, morfometrik özellikleri incelenmiş, ulaşılabilirlikleri ve ilgi çekebilecek yönleri araştırılmıştır. Sahayla ilgili ikincil veriler temin edilmiş, CBS kullanılarak görsel materyaller üretilmiştir. Tespit edilen yer şekillerinin jeomorfoturizm potansiyellerinin belirlenebilmesi için Jeosit Ön Değerlendirme Modeli (Preliminary Geosite Assessment Model-GAM) kullanılmıştır. Bu modele göre yer şekilleri ana ve ek değerlere göre 0-1 arasında puanlanarak, bir matrise yerleştirilmiş, düşük, orta ve yüksek seviyeleri gösteren “Z” alanları belirlenmiştir.

Durağan’da üç şelale, iki mağara, kanyon, volkanik şekiller ve kayalıklar olmak üzere, jeomorfosit olma potansiyeline sahip, sekiz yer şekli tespit edilmiştir. Bu şekiller GAM’a göre; Z21, Z22 ve Z32 alanlarındadır. Z21, orta seviyede ana, düşük seviyede ek değerlere, Z22 orta seviyede ana ve ek değerlere, Z32 ise yüksek seviyede ana, orta seviyede ek değerlere sahip jeomorfositleri göstermektedir. Tespit edilen şekillerin, işlevsel turizm değerlerinin düşük olması ve tanıtım eksikliği ek değer puanlarını, yöreyle ilgili akademik çalışmaların yetersizliği ise ana değer puanlarını düşürmüştür. Sonuçlara göre, Durağan’da en yüksek jeomorfoturizm değerine sahip yer şekilleri Kızılırmak Kanyonu ile Karakaya Kayalıkları iken en düşük değer Ağcaçal Mağarası’na aittir.

Durağan, konumu ve topoğrafyası nedeniyle sosyoekonomik imkânların kısıtlı, kırsal nüfusun ağırlıklı olduğu bir yerleşmedir. Bu gibi yerleşmelerde jeomorfoturizm gibi etkinlikler, bilinirliliği artırarak yöreyi ekonomik anlamda desteklemektedir. Durağan, jeomorfositleri ile bir açık alan dersliği niteliğindedir. Coğrafya başta olmak üzere pek çok yükseköğretim programının öğrencileri ile ortaöğretim öğrencilerinin ziyaret edilebileği bir uygulama alanı niteliğindedir. Bu anlamda Durağan’da tespit edilen yer şekillerinin tanıtılması, sürdürülebilir olarak jeomorfoturizme açılması Coğrafya bilimi, yöre ekonomisi ve bu yer şekillerinin korunması açısından önemlidir.
Sobre la necesidad de Filosofía contextual. Dussel y Roig, dos contribuciones para pensar el presente del filosofar latinoamericano
Authors: Bianchi José Ernesto , Irrazabal Astudillo Nadia Jimena
Published: November 2021

En este trabajo nos proponemos desarrollar dos visiones acerca del quehacer filosófico de Enrique Dussel y Arturo Roig, por considerar a ambas visiones paradigmáticas de dos de las grandes corrientes de ideas que animaron esta discusión, la Filosofía de la Liberación y la Historia de las ideas. Mediante una revisión bibliográfica sobre los autores, analizaremos las características del pensamiento filosófico hegemónico que buscan combatir y los supuestos que lo sostienen, señalando sus fracturas doctrinales y axiológicas, para luego ofrecer una posibilidad afirmativa frente al presente y al porvenir del filosofar latinoamericano. Finalmente, con el objeto de dar algo de luz sobre este problema general que abre el trabajo ¿Para qué una filosofía latinoamericana?, extraeremos algunas conclusiones sobre lo que deba ser nuestro filosofar, direccionadas en el sentido de abandonar la dicotomía entre teoría y praxis, como así también la prerrogativa aristotélica de la filosofía como un saber inútil y desafectado de su contexto.
La arabidad en la narrativa sudamericana de la segunda mitad del siglo XX y la literatura del Mahyar
Authors: Bartet Leyla
Published: November 2021

Desde finales del siglo XIX llega a las costas americanas una importante inmigración de origen levantino. Este movimiento migratorio se prolongó a lo largo del siglo XX dejando una huella profunda en la vida cotidiana y en la historia de nuestros pueblos. La experiencia del encuentro cultural es recogida ampliamente por el discurso literario que es espejo y proyección de nuestra identidad conflictiva, diversa y múltiple. La mayoría de los inmigrantes eran campesinos o pequeños comerciantes empobrecidos. Pero también llegaron a América intelectuales sirios, libaneses y palestinos que crearon círculos literarios e importantes escuelas que revolucionaron la producción literaria en lengua árabe: la llamada literatura del Mahyar. El estudio abordará el tema desde; el discurso literario del enunciante ajeno al mundo árabe, el discurso literario del enunciante árabe (o de origen árabe) y la literatura del Mahyar: el renacimiento literario árabe desde América.
