Tungsten metal powder, using a hydrometallurgical route, was extracted from tungsten heavy alloy scrap that was generated during machining of penetrator cores for the manufacture of Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS). The powder was subjected to extensive characterisation that included physical property evaluation and analysis of the alloy chemistry in order to assess its suitability for the preparation of tungsten heavy alloys with enhanced mechanical properties. Subsequently, a tungsten heavy alloy based on W-Ni-Co was consolidated using this powder through liquid phase sintering followed by heat treatment and swaging operations to realize long rods (~500 mm). This was followed by a detailed characterisation that included microstructure and mechanical property. The mechanical properties of these rods are promising, exhibiting a good balance of tensile and impact properties, which in turn underscores the potential of these recycled powders in the production of premium quality heavy alloy long rods for stringent applications such as kinetic energy penetrators.

Published: October 2023

Since the 1950s, the Brazilian automotive sector has been supported by different public policies until the present day. Despite the importance of the Brazilian automotive industry in the national and global scene, there is no concrete empirical research that correlates with the different public policies have shaped the progress of this sector in the country. Thus, this paper aims to evaluate how the different public policies contributed to the development of the Brazilian automotive sector. To capture those impacts, it is necessary to develop a methodological approach supported by a systematic review of the literature and research some specific indicators that will allow measuring the results. The results indicate that each of the public policies contributed different mechanisms for the redefinition of local strategies for the development of products, investments in technologies and innovation and the installation of new automakers in Brazil. The main limitations of the research are a large volume of fragmented information and the results of public policies not always easily measurable and available to allow a more concrete analysis of their effectiveness or provide elements that support the reformulation of new public strategies.

Authors: Kohlbeck Eloiza , Beuren Fernanda Hänsch , Santos Vanessa Maria
Published: October 2023

Goal: Analyze the benefits of the application of recycled polypropylene in the evaporation tray of refrigerators in a multinational company of electro-electronic equipment.
Design / Methodology / Approach: This research conducts a systematic literature review; performs a Life Cycle Analysis (LCA) of the polypropylene production, interpreting its results through a Pareto Diagram; and presents a case study in a multinational company of white line electro-electronic equipment.
Results: The LCA results point out that propylene and the components released by the chemical plant cause the main negative externalities under the environment and human health, so that during PP production, propylene is responsible for 72% of the impacts under global warming and 86% in the face of scarcity of fossil resources. Thus, the case study proposes recycling polypropylene, following the Circular Economy guidelines by aligning the proposal with the Zero Waste policy, with modular design, with Reverse Logistics, and with Sustainable Development Goals.
Research limitations: The work presents limitations inherent to literature review works, where filters are used to limit the search (limited to articles, published between 2012 and 2021 and written in English).
Practical implications: The research encourages recycling, pointing out its contribution under the environmental, social and economic spheres.
Originality / Value: The research presents originality and methodological value by combining qualitative and quantitative methods, and a theoretical and practical approach. Thus, it was possible to implement the research in the multinational company analyzed, and to measure the benefits obtained.

Casein and Banana Peel-Loaded Bacterial-Resistant Surgical Textiles
Authors: Saravanan M.
Published: October 2023

Today, the need for fabrics that resist the growth of microorganisms is rising rapidly, as bacteria and other microbes are resistant to any clean room environment. In particular, health care and hygiene textile products must be more bacterial resistant. This study thus concentrated on developing antibacterial surgical textile products using eco-friendly material, such as casein and banana peel, which were used to coat fabric using cyclodextrin as a cross-linking agent. In this research work, fabric was treated with banana peel, casein, and a combination of banana peel and casein, without cyclodextrin, while cyclodextrin-loaded fabric treated samples were tested for antimicrobial resistance (AATCC100-2004). The treated samples initially studied using FTIR showed a peak point at 3,278.99 cm-1, which infers the presence of an O-H group for banana peel extract, and at 3,340.71 cm-1, which infers the presence of an N-H group for casein. Antimicrobial tests against E. coli showed a bacterial reduction of 81.44%, while a reduction of 52.80% was recorded for S. aureus. An analysis of untreated and treated samples showed that treatment with extracts of an agent through the pad-dry-cure process did not have a significant effect on the tensile and air permeability characteristics of the samples.
Una aproximación cualitativa al impacto de la Ley 20.903 en la calidad de programas de formación inicial docente de la Universidad de Los Lagos
Authors: Barra-Ranni Mauricio , Guerrero-Molina Gustavo , Saavedra-Hernández Hugo , Soto-Silva Ignacio
Published: October 2023

En 2016 fue publicada la Ley 20.903, que establece regulaciones a las pedagogías en Chile, tanto en formación inicial docente (FID) como en el ejercicio profesional de dichas carreras. Así, se propone caracterizar los impactos iniciales y resultados de la Ley 20.903 y las normas de la Comisión Nacional de Acreditación (CNA) en las carreras pedagógicas de la Universidad de Los Lagos y analizar los resultados en sus niveles de calidad. El estudio constituye una profundización de un proyecto de investigación financiado por la CNA. Es un estudio de caso, en el cual se utilizó el enfoque cualitativo. Se aplicaron entrevistas a directores(as) y jefaturas de carrera, así como grupos focales a académicos(as) y estudiantes. Se concluye que la Ley 20.903 disminuiría la desregulación de las pedagogías: valorizaría la FID, mejoraría el currículo y estandarizaría la calidad. Aunque, participantes afirman que provocaría una homogeneización en la formación, por ende, relevan la necesidad de considerar el contexto territorial en el proceso formativo. Además, las nuevas exigencias de la ley derivarían en mayor burocratización en el proceso de acreditación de carreras pedagógicas y supondría un peligro para su sustentabilidad, ya que el aumento de los puntajes mínimos de ingreso perjudicaría la matrícula.

Published: October 2023

Optimization of optical and electrical properties of active semiconducting layers is required to enhance thin film solar cells' efficiency and consequently became the cornerstone for sustainable energy production. Computational studies are one of the ways forward to optimize solar cells’ characteristics. In this study, Silvaco-Atlas, a powerful software that excels in both 2D and 3D electrical simulations of semiconductors has been used for the simulation in order to investigate the solar cell properties. The architecture of the solar cell simulated was FTO/ZnO/In2S3/CuInS2/Mo. This study aims to optimize solar cell efficiency by optimizing film thicknesses and carrier concentrations via simulation. The designed solar cell was exposed to the presence of a sun spectrum of AM1.5 from a 1kW/m2 incident power density at 300K. The thickness values of the window (ZnO), absorber (CuInS2) and buffer (In2S3) layers were varied to record a solar cell's optimum thickness. The resulting FTO/ZnO/In2S3/CuInS2/Mo solar cell formed by simulation is presented. The best efficiency and fill factor of the solar cell simulated were found to be 41.67% and 89.19%, respectively. The recorded values of current density and the open circuit voltage of the cell were 40.33mA/cm2 and 1.15 V, respectively. Additionally, the maximum power of the simulated solar cell device was 41.68 mW. Optimization results revealed that the most efficient cell found was made up of a window layer with a thickness of 0.03μm, an absorber layer with a thickness of 6.0μm and a buffer layer with a thickness of 0.2μm. The optimized carrier concentration of ZnO, In2S3 and CuInS2 was respectively 1e21 cm-3, 1e20 cm-3, 3e18 cm-3 and the optimized Al-doped ZnO value was 1e25 cm-3. The Absorption spectra indicated that the solar cell's peak absorption occurs between 350 nm and 1250 nm and presented a good external quantum efficiency (EQE) of around 84.52% to 92.83% which indicates good efficiency in the visible domain. This performance is attributed to the transparency of FTO, ZnO and good absorption of In2S3 and CuInS2 thin films.
Comparative analysis of certainty factor and analytic hierarchy process for landslide susceptibility zonation in parts of Solan, Himachal Pradesh, India
Authors: Magray Adil Ahmad , Singh Kanwarpreet , Sharma Swati
Published: October 2023

The state of Himachal Pradesh in India is one of the most important hotspots when it comes to landslides; and Kandaghat, a tehsil in the Solan district of Himachal Pradesh having religious and tourism importance, is substantially affected by frequent landslides causing road blocking. In the present study, the analytic hierarchy process (AHP) and certainty factor (CF) techniques, which form part of the geographic information system (GIS)-based landslide susceptibility models, were used to prepare a landslide susceptibility map for the Kandaghat region, for which, as a preliminary step, an inventory of 214 live landslides was prepared from the Bhukosh data directory. The landslide inventory was cross-verified on the Google Earth platform. About nine landslide causative factors (slope, curvature, aspect, soil, rainfall, land use–land cover, lithology, drainage density and lineament density) were considered for the study area, and against the backdrop of these, the corresponding thematic maps were prepared and used in turn for the preparation of the final landslide susceptibility map. Based on the two mentioned techniques, the thematic maps were assigned weights according to their prominence and dynamic processes in the study area. The model performance for each method was evaluated using the area under the curve (AUC), and the accuracies for the AHP and CF were ascertained as, respectively, 81% and 85.6%. The Himalayan terrains are significantly prone to landslides, and this study outlines the characteristics of one of the important Himalayan towns in terms of vulnerability for landslides, together with providing its classification in terms of slope deformation susceptibility; this procedure can help direct attention towards areas needing to be classified under high to very high landslide susceptibility zones.
Watershed prioritization of drainage basins based on geomorphometric parameters, Neyyar watershed, India
Authors: Shekar Padala Raja , Mathew Aneesh
Published: October 2023

Prioritisation of sub-watersheds (SWs) is becoming increasingly important in the conservation of natural resources, particularly in watershed planning. In this study, sub-watershed for the Neyyar basin was prioritised using three methods: morphometric analysis, principal component analysis (PCA) and hypsometric analysis. Morphometric analysis and hypsometric analysis were carried out using remote sensing (RS) and geographic information system (GIS) techniques, while PCA was performed for dimensionality reduction of morphometric parameters. The watershed was divided into 11 sub-watersheds (SW1–SW11), and each sub-watershed was given priority. To rank and prioritise SWs, 15 morphometric parameters were selected from the quantitative measures of morphometric analysis, including linear, relief, and areal. PCA was used to rank and prioritise SWs based on three highly correlated morphometric parameters. The hypsometric integral (HI) values were determined using the elevation relief ratio approach, and HI values were utilised to prioritise SWs. For both methods, such as morphometric analysis and PCA, a higher priority has been given to SW1. Using hypsometric analysis, higher priorities have been assigned to SW1, SW7, SW8, SW9, SW10 and SW11. The most common SWs that belong to the same priority of SWs and have a high correlation between them among the three methods are SW1, SW2, and SW5.The results of this analysis indicate that SW1 is a common high priority area with a significant risk of soil erosion, runoff and peak discharge. Therefore, decision-makers may utilise the high-priority sub-watershed to guide planning and development, measure conservation efforts and manage the land to prevent.
Stylistyczno-składniowa struktura języka poetyckiego Iwana Nyzowego
Authors: Tielieżkina Ołesia
Published: October 2023

Autorka rozpatruje tkankę składniowo-stylistyczną twórczości wybitnego ukraińskiego poety Iwana Nyzowego, którego dorobek artystyczny dotychczas pozostaje poza zasięgiem zainteresowań językoznawców. Nieodłącznym składnikiem przestrzeni językowej poety są środki stylistyczne o charakterze składniowym. Badaczka analizuje funkcjonowanie w utworach poety takich środków stylistycznych, jak figury dodawania (anafora, epistrofa, homoioteleuton), figury gromadzenia (gradacja, polisyndeton, asyndeton), figury przemieszczenia (inwersja, chiazm), figury retoryczne (zwrot adresatywny, pytanie, negacja, afirmacja, okrzyk). Za pomocą wymienionych środków figuratywno-ekspresyjnych o charakterze składniowym poeta tworzy wyjątkową tonację emocjonalną tekstu poetyckiego, uwypukla swoją wypowiedź, układa swoisty rysunek rytmiczno-melodyczny i kreuje wyraziste kontury obrazu poetyckiego, a zatem jako autor osiąga najbardziej wyrazisty efekt stylistyczny w manifestacji swojego światopoglądu indywidualnego.

Published: October 2023

Proponowany artykuł jest poświęcony badaniu specyfiki strukturalnej i cech motywacji autorskich nazw dań w powieści Marii Matios Kulinarne figle. Badanie przeprowadzono w ramach onomazjologii poznawczej, która umożliwia identyfikację mechanizmów językowego znaczenia mentalnego leksykonu na podstawie różnych czynników świadomości. Scharakteryzowano cechy strukturalne autorskich nazw potraw, wyróżniono nomeny jednoskładnikowe, będące prostymi jednostkami sufiksowymi, oraz wieloskładnikowe, które są strukturalnie związane z kombinacjami wyrazów. Wyróżniono i opisano 12 typowych modeli nazw wieloskładnikowych. Zanalizowano powiązania motywacyjne między strukturą onomazjologiczną autorskich nazw potraw a semantyką i fragmentami wiedzy aktywowanymi w procesie nazywania. Stwierdzono, że kulinaryzmy formalnie i merytorycznie odzwierciedlają wybór motywatorów nazwy: składników, cech smakowych, sposobu przygotowania, dystrybucji lokalnej itp. Motywacja metaforyczna opiera się na przenoszeniu nazwy na podstawie zewnętrznego podobieństwa przedmiotów (kształt, kolor, wielkość), a także na skojarzeniach wartościujących i emocjonalnych. Zarejestrowano nazwy równoległe ze względu na dobór różnych motywatorów.
Mikroobraz jako sposób wizualizacji tekstu w małej prozie Iryny Sawki (na podstawie zbioru nowel "Korale z dzikiej róży")
Authors: Jankowska Żanna
Published: October 2023

Literatura jako dziedzina sztuki ma w swym repertuarze różnorodne formy i środki autoekspresji, które ostatecznie decydują o stopniu jej artyzmu. Należy do nich także mikroobraz (szczegół artystyczny). Współczesna pisarka ukraińska Iryna Sawka w swoich nowelach sięga nierzadko po mikroobrazy, które stają się istotną cechą jej prozy, czyniąc ją dobrze rozpoznawalną. Jej twórczość jak dotąd nie była jednak obiektem wnikliwszych badań literaturoznawczych, stąd też niniejszy artykuł można uznać za próbę włączenia nowelistyki Sawki do obszaru zainteresowań współczesnego dyskursu naukowego. Zwraca uwagę również fakt, że kluczowy mikroobraz pojawia się często w samych tytułach utworów Sawki, a następnie wokół niego nadbudowywana jest cała fabuła. W niniejszym badaniu uwzględniono szczególnie te mikroobrazy, które stanowią swego rodzaju wizualizację percepcji tekstu i najsilniej oddziałują na wyobraźnię czytelnika.

Published: October 2023

The purpose of this study was to explore the value of resting-state magnetic resonance imaging (MRI) based on the brain extraction tool (BET) algorithm in evaluating the cranial nerve function of patients with delirium in intensive care unit (ICU). A total of 100 patients with delirium in hospital were studied, and 20 healthy volunteers were used as control. All the subjects were examined by MRI, and the images were analyzed by the BET algorithm, and the convolution neural network (CNN) algorithm was introduced for comparison. The application effects of the two algorithms were analyzed, and the differences of brain nerve function between delirium patients and normal people were explored. The results showed that the root mean square error, high frequency error norm, and structural similarity of the BET algorithm were 70.4%, 71.5%, and 0.92, respectively, which were significantly higher than those of the CNN algorithm (P < 0.05). Compared with normal people, the ReHo values of pontine, hippocampus (right), cerebellum (left), midbrain, and basal ganglia in delirium patients were significantly higher. ReHo values of frontal gyrus, middle frontal gyrus, left inferior frontal gyrus, parietal lobe, and temporal lobe and anisotropy scores (FA) of cerebellums (left), frontal lobe, temporal lobe (left), corpus callosum, and hippocampus (left) decreased significantly. The average diffusivity (MD) of medial frontal lobe, superior temporal gyrus (right), the first half of cingulate gyrus, bilateral insula, and caudate nucleus (left) increased significantly (P < 0.05). MRI based on the deep learning algorithm can effectively improve the image quality, which is valuable in evaluating the brain nerve function of delirium patients. Abnormal brain structure damage and abnormal function can be used to help diagnose delirium.
„Sprachkontakte“ aus der Sicht der kontrastiven Linguokulturologie
Authors: Donec Pavel
Published: October 2023

The problem of language contacts has two main perspectives: as an interaction of several codes being quasi-independent actors and as interaction of two languages in the consciousness of a concrete individual – mostly the mother tongue and a foreign language. In this article, the second approach is advocated. As the mother tongue (“own language”) acts the Russian, and the German – as the foreign (“alien”) language. With language contacts of this kind (foreign language acquisition, interlingual/intercultural communication, translation), certain differences between the contact languages come to light. They are described from the point of view of contrastive linguoculturology – a discipline that is located in the overlapping zone between conventional contrastive linguistics and linguoculturology, which has been developing rapidly in recent times, especially in the former USSR. The notion linguocultural “contrast” is proposed for the role of the basic unit of this discipline: it is binary and composed of a “specialx” and a “lacunaey” (contrastx↔y = specialx + lacunaey). Three types of contrasts are distinguished: (1) system-linguistic, (2) discursive and (3) cultural.

3D thin-film nanofluid flow with heat transfer on an inclined disc by using HWCM
Authors: Alshehry Azzh Saad , Yasmin Humaira , Shah Rasool
Published: October 2023

Momentum and heat transmission influence the coated physical characteristics of wire product. As a result, understanding the polymeric movement and heat mass distribution is crucial. An increase in thermal efficiency is necessary for the wire covering technology. So, the aim of this work is to investigate the influence of nanomaterials on the heat and mass transport processes in wire coating analyses. A thin film nanofluid is used to investigate heat and mass transfer in three dimensions over a rotating inclined disc. Both the suction and injection effects of nanofluids and the thermal radiation of their fluxes are taken into account. By employing similarity variables, the set of governing equations can be transformed into a differential equation system. The necessary differential equation system is solved using the Haar wavelet collocation method. Plots and observations of the velocity distribution, concentration, and thermal fields within the boundary layer across an inclining, steadily rotating plane are made. Flow characteristics change as a result of varying embedded factors such as

Objectives

Cyclin-dependent kinase 5 (Cdk5) activity is specifically active in neurogenesis, and Cdk5 and neocortical neurons migration related biomarker are expressed in Cos-7 cells. However, the function of Cdk5 on the transformation of immortalized Cos-7 cells into neuronal-like cells is not clear.

Methods

Cdk5 kinase activity was measured by [γ-32P] ATP and p81 phosphocellulose pads based method. The expression of neuron liker markers was evaluated by immunofluorescence, real-time PCR, Western blot, and Elisa.

Results

P35 overexpression upregulated Cdk5 kinase activity in Cos-7 cells. p35 mediated Cdk5 expression promoted the generation of nerite-like outgrowth. Compared with the empty vector, p35-induced Cdk5 activation resulted in time-dependent increase in neuron-like marker, including Tau, NF-H, NF-H&M, and TuJ1. Tau-5 and NF-M exhibited increased expression at 48 h while TuJ1 was only detectable after 96 h in p35 expressed Cos-7 cells. Additionally, the neural cell biomarkers exhibited well colocation with p35 proteins. Next-generation RNA sequence showed that p35 overexpression significantly upregulated the level of nerve growth factor (NGF). Gene set enrichment analysis showed significant enrichment of multiple neuron development pathways and increased NGF expression after p35 overexpression.

Conclusion

p35-mediated Cdk5 activation promotes the transformation of immortalized Cos-7 cells into neuronal-like cells by upregulating NGF level.
End-User Threat Perception: Building Confidence to Make Decisions Ahead of Severe Weather
Authors: Olson Jillian R. , Doyle Claire M. , LaDue Daphne S. , Marmo Alex N.
Published: October 2023

Ahead of severe weather, National Weather Service (NWS) core partners are responsible for making decisions that ensure the safety of their jurisdiction. NWS defines core partners as government and nongovernment officials who make weather related decisions; this study uses the term “end-user” to refer to those individuals within emergency management, fire departments, public works, and school systems. Owing to the complex science of severe weather forecasting, many events turn out to be null events and end-users learn to be selective in which forecasts warrant extra preparations. While end-users state they would rather be overprepared than under prepared, end-users face varying consequences in the wake of null events that could lead them to be more hesitant in the future. Our team conducted background and event-based interviews with emergency managers, fire departments, public works, and school officials in various states across the United States east of the Rocky Mountains. Event-based interviews were separated into sets according to their Storm Prediction Center (SPC) risk level and coded thematically; this study specifically focuses on how end-users perceived the threat of severe weather in the hours ahead of its forecasted occurrence. Analyses concluded that (i) end-users in the same SPC risk level perceived threats differently, (ii) end-users in the SPC Enhanced risk had the most variation, and (iii) threat perceptions were driven by forecast information, the end-users’ personal experiences, and environmental cues. As SPC risk level increased, end-users increasingly applied information from the three themes to adjust their situational awareness and build confidence before making potentially costly decisions. By understanding the impacts of null events and how end-users gauge threats, the NWS can better support end-users and use null events as an opportunity to build trust and partnership with their core partners.
Autocrine/paracrine growth hormone in cancer progression
Authors: Zhang Xi , Pandey Vijay , Bhardwaj Vipul , Zhu Tao , Lobie Peter E
Published: October 2023

It is now apparent that growth hormone (GH), an anterior pituitary hormone predominantly regulating postnatal somatic growth and metabolism, is also expressed in extrapituitary tissues. An extrapituitary synthetic site of GH that has garnered interest is the de novo or enhanced expression of GH in carcinoma or other cancers. In a number of cancers, including carcinoma of the mammary gland, endometrium, liver, prostate, and colon, the expression of GH is independently associated with more advanced clinicopathologic parameters of the cancer. In some of these cancers, tumor human growth hormone (hGH) expression portends worse survival outcomes for patients. Functionally, tumor-derived hGH exerts both autocrine and paracrine functions on carcinoma cells and cancer-associated stroma. Expression of autocrine/paracrine hGH in cancer drives tumor growth, angiogenesis, metastasis, and resistance to therapy by promotion of cancer cell proliferation, survival, epithelial-to-mesenchymal transition, motility, invasion, cancer stem cell-like behavior, and metastasis. Autocrine/paracrine hGH activates oncogenic signaling pathways and specific transcriptome signatures and enhances the expression of an oncogenic secretome to promote these functions. Hence, extrapituitary expression of GH in cancer promotes cancer progression independent of endocrine hGH, and may be considered as a validated target in oncology.
Cambios y adaptaciones en las celebraciones religiosas frente a la pandemia del Covid-19.Estudio de las parroquias católicas de Santander, Colombia

Published: October 2023

Este artículo busca dar a conocer una parte de los resultados de la investigación “Consecuencias de la pandemia del Covid-19 en las iglesias cristianas de Santander. Aspectos económicos, religiosos y sociales”, y en particular expone y contextualiza la manera como las parroquias católicas de esta región de Colombia asumieron y respondieron a las restricciones e inconvenientes suscitados por la pandemia en lo referente a la práctica religiosa litúrgica, tales como la celebración de misas, de festividades religiosas y la administración de los sacramentos. Metodológicamente, se sirvió de la etnografía digital, de la realización de encuestas a párrocos y de la consulta de prensa y sitios de noticias en la web. Entre los resultados, se destaca la rápida adaptación material y simbólica de las parroquias a los nuevos formatos virtuales y a distancia, a pesar de la relativamente poca experiencia con que se contaba al respecto, lo cual les permitió ganar nueva feligresía temporal —aun internacional— que compensaba en parte las pérdidas de fieles ocasionadas por el cierre de templos y además la buena relación de colaboración que en general se tuvo con el gobierno y sus medidas para afrontar la pandemia. Los resultados pueden servir como punto de referencia para comprender la problemática, no solo en el ámbito nacional colombiano, sino, además, latinoamericano, y, finalmente, se invita a ahondar en investigaciones empíricas sobre el tema, que apenas comienzan a darse en nuestro contexto.
Tendencias didácticas en los textos colombianos para enseñar filosofía en Bachillerato (1994-2003)
Authors: Prieto Galindo Fredy Hernán , Salcedo Ortiz Eduardo
Published: October 2023

Este texto presenta los resultados de una investigación realizada en la Universidad Pedagógica Nacional durante el primer semestre de 2018. El objetivo principal de la investigación consistió en identificar las tendencias didácticas de los textos editados en Colombia para la enseñanza de la filosofía en bachillerato durante la década 1994-2003. Desde el método de análisis de contenido, se identificaron las tendencias didácticas y se evaluaron los recursos didácticos como las imágenes, las citas textuales, las redes conceptuales, etc. Los resultados muestran dos tendencias didácticas: primero, la pedagogía tradicional y el constructivismo son los modelos pedagógicos predominantes; segundo, la mayoría de libros tratan que el estudiante establezca relaciones entre la filosofía y el contexto sociocultural colombiano.
Explicando las diásporas políticas
Authors: Abu-Tarbush José , Cabrera Abu Nasara
Published: October 2023

La importancia de las diásporas en la política mundial se ha ido acrecentando durante las últimas décadas, sin desmerecer la atención de la que previamente han sido objeto a lo largo de la historia contemporánea. Diferentes autores ponen de manifiesto que ese creciente rol y relevancia de las diásporas en los asuntos mundiales no se ha visto acompañado, de manera equivalente, por el desarrollo de una teoría afín en la disciplina de las Relaciones Internacionales. El objetivo del presente artículo es recoger las principales perspectivas que explican la aparición, desarrollo y evolución de las diásporas, con especial énfasis en la construcción de las diásporas políticas. Sin pretensión de exhaustividad, se realiza un breve recuento de aquellas aproximaciones teóricas que permiten una mayor comprensión de las diásporas en general y de las diásporas políticas en particular. Se parte de una óptica constructivista, en desafío de las aproximaciones esencialistas, con el propósito de contribuir a un marco teórico desde el que explicar las diásporas políticas, propiciando una revisión bibliográfica sobre las mismas en el campo de las Relaciones Internacionales. Para ello, se da cuenta del origen del concepto de diáspora, su evolución, las aproximaciones clásicas (citando a aquellos autores más relevantes que partían de una perspectiva más estructuralista); y las perspectivas más recientes e innovadoras con una óptica más compleja y heterogénea de las mismas (de mayor diversidad interna y con un mayor número de espacios relacionales). De este modo, se parte de una concepción de las diásporas como construcciones sociales y políticas que, más allá de contener unos rasgos definitorios básicos, son comunidades transnacionales que surgen tras específicos procesos de movilización. Es en este marco concreto de las diásporas políticas en el que se establece su relación con los conflictos, la globalización y las tecnologías de la información y la comunicación (TIC); para acabar describiendo su construcción y evolución en un marco global donde el dinamismo sociopolítico de las diásporas está relacionado de manera compleja con el grado de integración o exclusión de sus miembros en sus sociedades de acogida, así como con la situación (de conflicto o no) de sus estados originarios, apuntando a una mayor longevidad de aquellas diásporas definidas como víctimas o cuya emergencia radica en su expulsión o salida forzada del país natal o de origen.

This paper investigates the usage of singular and plural forms of address in contemporary Lithuanian. The object of the research is the pronouns tu and jūs, and second-person verbs. The aim of the present study is to analyze how and why singular and plural forms of address are used and which social and psychological factors determine this usage. The research data consists of 111 discourse completion tests filled by university students. For a deeper insight, 6 semi-structured in-depth interviews with students and young people who have just finished their studies were also conducted. Quantitative and qualitative research methods were combined for both data collection and analysis.Based on the results, it can be concluded that the distribution of forms of address in situations where the sociolinguistic and pragmatic choice was not obvious was approximately equal. Statistically significant variables were found to be sex and age. However, as the qualitative aspect of the study reveals, the usage of these forms depends on diverse and subtle variables, including social distance, relative power, and age, as well as their interaction within specific communicational situations. The study confirms that plural forms of address generally convey respect, formality, and polite distance, while singular forms indicate friendliness, intimacy, and familiarity. Nevertheless, both formal and informal forms of address can also be employed as impoliteness strategies. In some cases, the switch between the forms of address is caused by mutual agreement, while in others, it occurs on its own and indicates changes in social or psychological circumstances. The choice between singular and plural forms of address is often complex and not always fluent; therefore, interlocutors may seek to avoid them altogether and navigate a delicate balance between formal and informal ways of addressing people.

Purpose: to investigate and experimentally substantiate the forms of increasing the need-based motivation of students to engage in physical education in the main institution of a new type based on different modes of motor activity. Materials and methods: in order to identify the structure and features of the need-motivational characteristics of physical culture among students of new-type educational institutions, two questionnaires were conducted among 104 students of 10 classes of secondary schools and lyceums in Slovyansk. Questionnaires were conducted at the beginning and at the end of the study. School students formed the control group, and lyceum students formed the experimental group. Results: no age differences between the analyzed groups were found, in the process of the questionnaire, more than half of high school students (54.2%) believe that the number of lessons per week should be increased to three times, 20.0% are inclined to two one-time classes and 25.8% of students would like to increase the number of physical education lessons to four times a week. Among students of secondary schools and lyceums in general, a common regularity of the importance of motives is revealed, however, the values of individual motives differ, sometimes significantly. Conclusions: Experimentally proven promising application in educational institutions of a new type of different-level variants of motor activity of schoolchildren.

Otolith traits such as size and mass were investigated in 60 fish specimens of C. kais and C. macrostomum collected from the Tigris River, Şırnak region, Türkiye collected from September 2015 to December 2015. The purpose of this work was to determine the asymmetry level in the otolith length (OL), otolith width (OW), and otolith mass (OM). OL's rate of asymmetry was greater than OW’s and OM's. The asymmetry in the three otolith traits rose with the fish length. The plausible reason for asymmetry in the otolith features explored has been considered relative to the inconsistency of growth triggered by ecological influence associated with the inconsistency in water temperature, salinity, depth, and contaminants occurring in the Tigris River System.

Amblypygi have a tropical and sub-tropical distribution and their first of the four pairs of legs, is modified as feelers. Their activity period and dark habitats render visual cues ineffective and they rely on non-visual sensory perception. There is agreement among researchers that the whip spiders invest in olfactory and tactile senses imparted by sensory structures concentrated on the tarsal segment of the first pair of long, well-articulated non-ambulatory legs that are constantly moved in all directions to sample the environment for detecting location of prey, as also for navigating. This is the first attempt to elucidate the sensory structures present on the antenniform legs of the whip spider, Phrynichus phipsoni (Pocock, 1894), collected from the state of Goa, India; using scanning electron micro[1]scope, and paves way for further research on sensory biology of this cryptic arachnid order. The examined specimen generally conforms to the diversity and morphology of sensory assemblage on the antenniform legs reported in other amblypygi species. Sensory structures elucidated include terminal trident tarsal claws, tarsal organ, bristles, porous sensilla, club sensilla, rod sensilla, slit sensilla, trichobothria, plate organ, pit organ and foliate leaf like hairs.
