Authors: Mohamed Abdalla Abdelrahim Elnur
Published: March 2023

The article is devoted to the main stages of the formation and development of foreign economic relations between Sudan and the USSR, starting with the establishment of Soviet-Sudanese diplomatic relations in 1956 and up to the end of the 1980s. The purpose of this article is to study the main directions of Soviet-Sudanese economic and scientific-technical cooperation in the context of political relations between the two countries in the period under study. The author relies on the principles of modern historical science: reliability, scientific objectivity and historicism, as well as a number of general scientific and special historical methods, in particular, chronological and historical-comparative. The object of the study is the Soviet-Sudanese economic relations in the 1960s-1980s. The subject of the study is the forms, directions and mechanisms of interaction between Sudan and the USSR in the economic sphere. It is shown how the unstable internal political situation in the country, the constant struggle for power between the military and civilians had a direct impact on the level of bilateral relations. The main directions of trade and economic cooperation between the Sudan and the USSR are revealed, which concerned, among other things, the sphere of geological exploration, construction, personnel training, and the exchange of specialists. Special attention is paid to military-technical bilateral cooperation, which was most actively developed during the presidency of Jafar Mohammed Nimeiri. The conclusion is made about the role of the USSR in the diversification of Sudan's industrial production, the restructuring of its monocultural economy and, in general, in the development and strengthening of the state sector of the country's economy.

Russian Formalism in Practice: A Narratological Reading of Joseph Conrad's Youth
Authors: Poursanati Susan , Ghodrati Asghar
Published: March 2023

Conrad's shorter works of fiction are mostly ignored in the formalistic analysis of his critics. Therefore, in order to fill the gap in the literature associated with the narrative structure of Conrad's shorter works, the authors of this article consider in detail the ideas of Genette's narratology for Conrad's story "Youth, Narration". Narratology, the method used in this article, is a science of literature that originated in the works of Russian formalists and is engaged in the systematic study of narratives. The purpose of this science is to identify the basic structures and relationships involved in the creation of history and its meaning. To achieve this goal, the theorists of narratology have introduced and defined a number of language rules that separate all narratives written in all languages. The scientific novelty of the work lies in the fact that in practice the narratological reading of the material is shown, and also shows how the authors apply these structural rules to their texts. Genette, a French narratologist, introduced five narrative categories in his book Narrative Discourse; these categories include Order, Duration, Frequency, Mood, and Voice. This article discusses Genette's narrative categories applied to Joseph Conrad's short story "Youth, Narrative" and identifies the structural nuances of this story in order to help readers in general and those who study literature, in particular, to touch upon a careful reading of Conrad's writing style.

Any teacher, when faced with various problematic and stressful situations in his professional activity, should be able to solve them promptly and effectively. To do this, first of all, he must have a low level of anxiety, since increased anxiety negatively affects the ability to rationally solve problematic situations. We organized and conducted a study on the basis of Secondary School No. 12. Krasnoyarsk. 37 teachers of the school took part in it. The purpose of the study was to study the relationship between anxiety and the social status of a secondary school teacher. We hypothesized that secondary school teachers with different social status in the group are characterized by differences in anxiety indicators, both in severity and in the ratio of its individual components.1. Teachers with pronounced anxiety can occupy any status position, i.e. they can have any number of choices, both positive and negative. The social status is not affected by the level of anxiety among teachers 2. There is a relationship between anxiety and the factors that cause it, namely: between anxiety and frustration, between anxiety and self-expression, between anxiety and fear of colleagues. Thus, the main hypothesis put forward by us that secondary school teachers with different social status in the group are characterized by differences in anxiety indicators, both in severity and in the ratio of its individual components, has not been confirmed. This means that modern teachers do not worry about their position, status, authority in the group.
The specifics of the choreographic interpretation of the main characters in the ballet "Zephyr and Flora, or Metamorphoses" (2021) in the context of modern plastic trends.
Authors: Khokhlova Daria
Published: March 2023

In this article, an attempt is made to comprehend the features of the choreographic embodiment of the images of the main characters (Zephyr and Flora) by choreographer A.S. Belyakov in the play "Zephyr and Flora, or Metamorphoses" (2021). This ballet is a modern appeal to the theme of the pre–romantic ballet Sh. Didlo (early XIX century). Such a plan cannot but be relevant, as well as the study of its creative results, first carried out in this article. Based on the methods of ballet studies analysis approved by Russian historians and ballet theorists (Dobrovolskaya, Krasovskaya, Slonimsky, Surits), the author applied comparative historical, ideological, artistic and analytical methods, as well as the method of included observation (based on personal experience working on the part of Flora). The main research tools were analytical description and semantic analysis of the variation of Zephyr and the duet of Zephyr and Flora. With their help, we managed to draw the following conclusions. The choreographic vocabulary of the fragments is distinguished by an organic combination of classical positions and pas with the author's movements (pictorial, ornamental poses; somewhat broken positions of the arms and body; originally modified technical elements). The dramaturgy of the modern reading of the plot of the pre-romantic ballet is developed by the choreographer by plastic (not pantomime) means in key dance fragments. Thus, the choreographic embodiment of the images of Zephyr and Flora demonstrates an organic synthesis of the ideological idea and the general aesthetics of pre-romantic ballet with the unconventionality and innovation of the modern author's plastic solution.
Fourth High-Lift Prediction/Third Geometry and Mesh Generation Workshops: Overview and Summary
Authors: Rumsey Christopher L. , Slotnick Jeffrey P. , Woeber Carolyn D.
Published: March 2023

The Fourth AIAA Computational Fluid Dynamics (CFD) High Lift Prediction Workshop and the Third Geometry and Mesh Generation Workshop were held collaboratively with the common goal of assessing the numerical prediction capability of current-generation computational fluid dynamics technology for swept medium-/high-aspect-ratio wings in high-lift configurations. A key aspect of this joint endeavor was the use of technology focus groups: an innovative new approach for workshops involving close collaboration between participants. These groups, which included both mesh-generation and flow-solver experts, worked to accelerate advancements for their particular methodologies by addressing key questions of importance before the workshop. The high-lift version of the NASA Common Research Model (CRM-HL) configuration was the focus of this workshop. Measured experimental wind-tunnel data were available for comparison. The workshop also included a two-dimensional turbulence model verification exercise based on the CRM-HL wing shape. Altogether, 44 participants submitted a total of 184 datasets of CFD results. This paper provides a high-level summary of the results and conclusions from the workshop. Like at past workshops, fixed-grid Reynolds-averaged Navier–Stokes methods continued to be inaccurate and inconsistent for predicting high-lift flow physics near maximum lift conditions. However, mesh adaptation definitively brought more consistency. Scale-resolving methods appeared most promising for predicting high-lift flow physics near maximum lift.
Semi-Supervised Active Learning for Anomaly Detection in Aviation
Authors: Memarzadeh Milad , Matthews Bryan , Templin Thomas , Sharif Rohani Aida , Weckler Daniel
Published: March 2023

Anomaly detection in commercial aviation is an extremely challenging yet crucial task. Accurately detecting operationally significant anomalies can save civilian lives and/or result in significant savings in maintenance cost. The current practice uses manually tuned rule-based mechanisms to flag exceedances from predefined safety boundaries. However, this system cannot identify unknown risks and emerging vulnerabilities. Recently, innovative approaches based on machine learning have been used to automate anomaly detection. However, there are limits to their applicability in the field of aviation due to several challenges: 1) Properly reviewed data are scarce in aviation and, as a result, supervised learning cannot reach optimal performance. 2) Operationally significant anomalies do not coincide with statistically significant ones and, as a result, unsupervised learning fails to provide reliable and robust performance. In this paper, we propose a semi-supervised active learning framework for anomaly detection (SALAD), which detects operationally significant anomalies in flight operational quality assurance data. The developed framework works with vast amounts of unlabeled data as well as a small quantity of labeled data reviewed by subject matter experts to reliably identify safety anomalies in flight operations. Moreover, the model’s active learning strategy allows it to detect unknown anomalies that might emerge in the system. We validate the performance of the SALAD with a real-world case study of anomaly detection during the approach to landing of commercial aircraft. We specifically show that the proposed framework reaches reliable performance when only 1% of the data is labeled and can identify unknown anomalies effectively.

Published: March 2023

Objectives:

Treatment of developmental dysplasia of the hip (DDH) with high hip dislocation in children using a one-stage operation appears tedious and associated with complications. This study aimed to assess a less traumatic approach for the surgical treatment of irreducible hips among children with DDH after walking age. The treatment strategy involved open reduction (OR) alone and non-invasive monitoring of acetabular development.

Methods:

This was a retrospective analysis of 22 hips of 20 female patients with complete dislocation of the hip and a mean age of 25.09 ± 4.6 months, performed between February 2013 and February 2018. All DDH patients underwent OR alone and had an irreversible hip dislocation. After surgery, a spica cast was applied for 6 weeks and then reduced to a broomstick cast for a considerable period. Finally, night abduction brace was placed until a normal acetabular index (AI) was obtained. The mean follow-up was 44.60 ± 12.36 months.

Results:

Out of 20 patients with DDH, 18 (90%) were successfully treated by OR alone. The main pre-operative AI of 41.82° ± 5.54° decreased to 16.19° ± 7.09° at the final follow-up (P < 0.001). An initial negative center-edge angle at the pre-operative stage gradually increased to a mean of 26.86° ± 6.56° during the follow-up period.

Conclusion:

Relatively less invasive approach adopted in this study not only obviated the need for an additional procedure but also had a favorable effect on the acetabular and hip joint development.

Published: March 2023

Цель исследования – выявление поэтических особенностей геокультурной модели «Дьоллоох Дьокуускай» (Счастливого Якутска), формирующейся в 50–80-ых гг. ХХ в. Задачами статьи являются выявление художественных элементов, складывающихся в единый текст Счастливого Якутска; определение качественных характеристик геокультурной модели «города-университета»; актуализация идеи созидания как основного лейтмотива национальной прозы 50–80-ых гг. ХХ в. Новизна исследования заключается в изучении модели «города в городе» – города-университета, студенческого городка Сэргэлээх, объединяющем в своем едином смысловом спектре структурные уровни Счастливого Якутска: эволюцию героя, мотив мечты, концепт счастья и молодости и др. Достаточно интересно интерпретируется в спектре национально-поэтической образности концепт белого теплохода, который может быть интерпретирован как олицетворение мечты человека в узком смысле и как образ советского абсолютизма, торжественного и мощного, в широком понятии. В результате определены поэтические особенности городской культурной модели «города-университета» как основной хронотопической системы в модели Счастливого Якутска; выявлены место и роль героя прозы 50–80-ых гг. ХХ в., сознание которого чрезвычайно отзывчиво к модификациям окружающего ландшафта.

The purpose of the study is to identify the poetic features of the geocultural model «Dyolloh Dyokuuskai» (Happy Yakutsk), which was formed in the 50–80s of the twentieth century. The objectives of the article are to identify the artistic elements that form a single text of Happy Yakutsk; to determine the qualitative characteristics of the geocultural model of the «city-university»; to actualize the idea of creation as the main leitmotif of national prose of the 50–80s of the twentieth century. The novelty of the research lies in the study of the model of a «city within a city» – a university city, a student town of Sergeleeh, combining in its single semantic spectrum the structural levels of Happy Yakutsk: the evolution of the hero, the motive of dreams, the concept of happiness and youth, etc. It is quite interesting to interpret the concept of a white motor ship in the spectrum of national poetic imagery, which can be interpreted as the personification of a person's dream in a narrow sense and as an image of Soviet absolutism, solemn and powerful, in a broad concept. As a result, the poetic features of the urban cultural model of the «university city» as the main chronotopic system in the model of Happy Yakutsk are determined; the place and role of the prose hero of the 50–80s of the twentieth century, whose consciousness is extremely responsive to modifications of the surrounding landscape, are revealed.
Legal status of indigenous communities in natural resource management
Authors: Доржеева В.В. , Слепцова О.Ю.
Published: March 2023

Статья посвящена актуальной теме правового статуса общин коренных малочисленных народов в сфере природопользования. Правовой статус общин КМНС в сфере природопользования включает комплекс правомочий, реализация которых при ведении традиционной хозяйственной деятельности требует дополнительных мер государственной поддержки. Приведен анализ действующего российского законодательства с учетом недавних изменений и дополнений. Отмечено, что поправки в законодательство расширили сферу хозяйственной деятельности общин и закрепили право общин осуществлять предпринимательскую и иную, приносящую доход деятельность, если она соответствует целям их создания. Сделан вывод, что основные отличия в правовом статусе общин КМНС как участников земельных, лесных, ресурсных отношений состоят в безвозмездном характере пользования отдельными видами ресурсов и порядке пользования. Однако проблемы в области реализации прав на природные ресурсы сохраняются. Статус общин КМНС в сфере природопользования можно оценить как формально равноправный, но фактически пониженный по сравнению с другими субъектами. Многие закрепленные в законодательстве субъективные права не могут быть реализованы общинами в силу ряда объективных причин, которые порождают необходимость дополнительных мер государственной поддержки.

The article is devoted to the topical issue of the legal status of indigenous minority communities in natural resources management. The legal status of indigenous communities in nature management includes a set of powers, the realization of which requires additional measures of state support in carrying out traditional economic activities. The article provides an analysis of the current Russian legislation with regard to recent amendments and additions. It is noted that the legislative amendments have expanded the scope of economic activities of communities and secured the right of communities to carry out entrepreneurial and other income-generating activities, as long as these are consistent with the objectives for which they were established. It is concluded that the main differences in the legal status of indigenous minority communities as participants of land, forest, and resource relations lie in the gratuitous nature of the use of certain types of resources and the order of use. However, problems in the field of realization of rights to natural resources persist. The status of indigenous communities in nature management can be assessed as formally equal, but actually lower than that of other subjects. Many of the subjective rights enshrined in the legislation cannot be implemented by communities due to a number of objective reasons, which generate the need for additional measures of state support.

Published: March 2023

Generating or even retaining slow magnetic relaxation in surface immobilized single-molecule magnets (SMMs) from promising molecular precursors remains a great challenge. Illustrative examples are organolanthanide compounds that show promising SMM properties in molecular systems while surface immobilization generally diminishes their magnetic performance. Here, we show how tailored Lewis acidic Al(III) sites on silica surface enable the synthesis of a material with SMM characteristics via chemisorption of (Cpttt)2DyCl ((Cpttt)= 1,2,4-tri(tert-butyl)- cyclopentadienide). Detailed studies of this system that also include its diamagnetic Y analogue indicate that the interaction of the metal chloride with surface Al sites results in a change of the coordination sphere around the metal center inducing for the dysprosium-containing material slow magnetic relaxation up to 51 K with hysteresis till 8 K and an effective energy barrier (Ueff) of 449 cm-1, the highest reported thus far for a supported SMM.

Published: March 2023

The synthesis of well-defined materials as model systems for catalysis and related fields is an important pillar in the understanding of catalytic processes at a molecular level. Various approaches employing organometallic precursors have been developed and established to make monodispersed supported nanoparticles, nanocrystals, and films. Using rational design principles, a new family of precursors based on group 10 metals suitable for the generation of small and monodispersed nanoparticles on metal oxides has been developed. Particle formation on SiO2 and Al2O3 supports is demonstrated, as well as the potential in the synthesis of bimetallic catalyst materials exemplified with a PdGa/SiO2 system capable in the hydrogenation of CO2 to methanol. In addition to surface organometallic chemistry (SOMC), it is envisioned that these precursors could also be employed in related applications such as atomic layer deposition, due to their inherent volatility and relative thermal stability.

The lead optimization process in drug discovery campaigns is an arduous endeavour where the input of many medicinal chemists is weighed in order to reach a desired molecular property profile. Building the expertise to successfully drive such projects collaboratively is a very time-consuming process that typically spans many years within a chemist's career. In this work we aim to replicate this process by applying artificial intelligence learning-to-rank techniques on feedback that was obtained from 35 chemists at Novartis over the course of several months. We exemplify the usefulness of the learned proxies in routine tasks such as compound prioritization, motif rationalization, and biased \textit{de novo} drug design. Annotated response data is provided, and developed models and code made available through a permissive open-source license.
The Accumulation of Antifreeze Proteins on Ice is Determined by Adsorption
Authors: Thosar Aniket U , Shalom Yitzhar , Braslavsky Ido , Drori Ran , Patel Amish J
Published: March 2023

Antifreeze proteins (AFPs) facilitate the survival of diverse organisms in frigid environments by adsorbing to ice crystals and suppressing their growth. The rate of AFP accumulation on ice is determined by an interplay between AFP diffusion from the bulk solution to the ice-water interface and the subsequent adsorption of AFPs to the interface. To interrogate the relative importance of these two processes, here we combine non-equilibrium fluorescence experiments with a reaction-diffusion model. We find that as diverse AFPs accumulate on ice, their concentration in the aqueous solution does not develop a gradient but remains equal to its bulk concentration throughout our experiments. These findings lead us to conclude that AFP accumulation on ice crystals, which are smaller than 100 microns in radius, is not limited by the diffusion of AFPs, but by the kinetics of AFP adsorption. Our results imply that mass transport limitations do not hinder AFPs from performing their biological function.

Published: March 2023

La democracia liberal experimenta actualmente un desapego ciudadano del que forma parte el populismo, un fenómeno especialmente presente en los países latinoamericanos. Sin embargo, la tesis de que el populismo caracteriza la política en Latinoamérica todavía necesita estudios micro en países concretos. En este artículo, se ofrece una definición operativa de populismo, se propone un código de análisis que recoge las características principales de este fenómeno y se aplica a los spots de los candidatos que llegaron a la segunda y definitiva vuelta en las últimas dos elecciones presidenciales de 2015 y de 2019 en Guatemala. Los resultados confirman la presencia del populismo en los spots, pero la ausencia de algunos de los rasgos lleva a plantear unas campañas de populismo mitigado. Al mismo tiempo, no todos los candidatos recurren a él con la misma intensidad.

Los mapas mediáticos son herramientas fundamentales para el estudio y análisis de los procesos de comunicación en una región. En el caso de Hispanoamérica los ejemplos disponibles son pocos e incompletos. El objetivo de esta investigación es la construcción de un mapa inédito y actual del dominio de la prensa hispanoamericana y, para ello, recurrimos metodológicamente a una minuciosa identificación de medios a partir de una revisión de las publicaciones científicas en las revistas de Comunicación indexadas en Web of Science y Scopus. Los resultados del estudio identifican 2.403 medios de comunicación; de ellos casi nueve de cada diez son tradicionales, lo que da cuenta que los nuevos medios nativos digitales no logran aún visibilidad académica. Los países con mayor cantidad de medios de comunicación son Argentina, México, Colombia, Ecuador y Chile. Aunque el mapa de medios supone una aproximación sesgada al construirse sobre los medios elegidos por la comunidad científica en función de sus intereses particulares, ofrece un sólido acercamiento por la amplitud de datos recabados y la correlación establecida con los indicadores socioeconómicos.
On the Properties of Bias-Variance Decomposition for kNN Regression
Authors:   Sobolev Institute of Mathematics SB RAS, Nedel’ko V. M.
Published: March 2023

When choosing the optimal complexity of the method for constructing decision functions, an important tool is the decomposition of the quality criterion into bias and variance. It is generally assumed (and in practice this is most often true) that with increasing complexity of the method, the bias component monotonically decreases, and the variance component increases. The conducted research shows that in some cases this behavior is violated. In this paper, we obtain an expression for the variance component for the kNN method for the linear regression problem in the formulation when the “explanatory” features are random variables. In contrast to the well-known result obtained for non-random “explanatory” variables, in the considered case, the variance may increase with the growth of 𝑘.

Published: March 2023

We study the first mixed problem for the telegraph equation with a nonlinear potential in the first quadrant. We pose the Cauchy conditions on the lower base of the domain and the Dirichlet condition on the lateral boundary. By the method of characteristics, we obtain an expression for the solution of the problem in an implicit analytical form as a solution of some integral equations. To solve these equations, we use the method of sequential approximations. The existence and uniqueness of the classical solution under specific smoothness and matching conditions for given functions are proved. Under inhomogeneous matching conditions, we consider a problem with conjugation conditions. When the given data is not smooth enough, we construct a mild solution.

Published: March 2023

Probabilistic Law Discovery (PLD) is a logic based Machine Learning method, which implements a variant of probabilistic rule learning. In several aspects, PLD is close to Decision Tree/Random Forest methods, but it differs significantly in how relevant rules are defined. The learning procedure of PLD solves the optimization problem related to the search for rules (called probabilistic laws), which have a minimal length and relatively high probability. At inference, ensembles of these rules are used for prediction. Probabilistic laws are human-readable and PLD based models are transparent and inherently interpretable. Applications of PLD include classification/clusterization/regression tasks, as well as time series analysis/anomaly detection and adaptive (robotic) control. In this paper, we outline the main principles of PLD, highlight its benefits and limitations and provide some application guidelines.
Determination of torque for milling working equipment of excavator when repairing a pipeline
Authors: Kuznetsov I. S.
Published: March 2023

Introduction. During the overhaul of the pipeline to remove the soil under the pipe, a trench tool is currently used. The new technology of excavation of soil under the pipeline proposed by the authors, which provides for the use of replaceable milling working equipment for a hydraulic excavator, makes it possible to increase the speed of repair work. The purpose of the article is a theoretical study of the process of interaction between the structural elements of milling equipment and the developed soil.Methods and materials. Based on the basic provisions of the theory of interaction of the working bodies of earthmoving machines with the soil, a mathematical model of the work of the milling working equipment of a hydraulic excavator was created. It makes possible to get the dependence of the resistance forces arising on the cutters of the working equipment, on its design parameters and the physical and mechanical properties of the soil.Results. According to the results of the analysis of the obtained dependence of the torque on the cutting angle and the angular speed of rotation of the milling head, it was found that the greatest influence on the torque required to overcome the forces of soil resistance and the drive of the working body is exerted by the angular speed of rotation of the milling head. The minimum value of the torque in the study area 50 N·m is observed at the point where the cutting angle of the soil is 45º, and the angular speed of rotation of the milling head is 4 rad/sec. The maximum torque 215 N·m was recorded at a cutting angle of 65º and a milling head speed of 10 rad/sec.Сonclusions. According to the results of the theoretical study of the process of cutting soil with the help of the milling working equipment of the excavator, the torque of the hydraulic motor necessary to rotate the milling head was established. The results of the theoretical studies carried out are recommended to be used to calculate the design and operating parameters in the design and creation of an experimental sample of milling working equipment.

Authors: García Gutiérrez Zaily del Pilar , Herrero Hernández Alejandra , Dumett Arrieta Simón Antonio , Gallo Bohórquez Linda , Tabares Salazar Adriana
Published: March 2023

Al leer este libro, hay que dejarse tocar por la travesía educativa realizada por los autores, compartir sus brújulas, mirar con asombro a su estrella polar, dejarse guiar por sus mapas e tinerarios y asumir la presencia del inesperado, que todo viaje conlleva. Este libro narra el resultado de un proceso de investigación interdisciplinar y multisectorial, donde participan el Departamento de Filosofía de la Facultad de Ciencias Humanas y Sociales, la Facultad de Educación y varios programas como Trabajo Social y Psicología, así como el Grupo MARFIL además tiene en cuenta e incluye la voz de instituciones educativas dedicadas a la infancia (jardines infantiles, fundaciones, ludotecas, centros culturales). Esta característica demarca una ruta de investigación educativa muy necesaria en el siglo XXI, principalmente teniendo en cuenta el foco epistemológico, que se revela en el título: Ciudadanía creativa desde el fomento del pensamiento crítico, ético y creativo en niños y niñas de primera infancia como actores sociales y constructores de paz. Este libro une el papel del pensamiento a la fuerza de la acción de las infancias2, que pueden (¡y deben!) ser vistas como ciudadanas. Por lo tanto, la importancia de esta publicación es primordial para el contexto colombiano, pero también lo es para otros contextos.
Suburban Forestry: An Investigation into the Reuse of Native Timber in Aotearoa
Authors:   , Hannah Alexander
Published: March 2023

Cities in Aotearoa are undergoing a rapid increase in density as a response to the national housing crisis. As a result, the production of building materials and large-scale demolition create mass carbon emissions and vast quantities of waste, exacerbating the ongoing global environmental crisisAs density and demolition have increased, the country’s older housing stock has declined. Notably, the large quantity of state houses built throughout the 1930s-50s has seen a steady decrease. Rapid clearance of these houses to provide space for new government builds has sent much of the native timber with which these houses are constructed to landfills. As logging of native trees has essentially disappeared in Aotearoa, due to the historical depletion of forests, any native timber that ends up as demolition waste is unlikely to be replaced.

This thesis examines how architectural solutions can facilitate the preservation and reuse of this native timber. Through an iterative design exploration, this research examines how heritage and sustainability can be explored through material reuse. Physical and speculative investigations have informed an understanding of the qualities of reused native timber and how these influence the design process.
Narrative Scenes on Medieval Metalwork. (c2023)
Authors:   ,   Lebanese American University, Hariz Mira
Published: March 2023

The Seljuqs are a tribe from Oguz origins who came into Central Asia from the Eurasian Steppe1. The Turkic dynasty ruled over the area from 1040 to 11942. They were known for their warfare skills, and eventually their rule spread westward through the Atabegs3. Between the 11th and 13th centuries, the region witnessed political unrest. However, art production under the Seljuqs thrived4. One of the materials of which many objects survived is metalwork. The surfaces of these objects are adorned with various decorative schemes which include, enthronement scenes, court entertainment scenes, hunting scenes, astrological symbols, vegetal motifs, and geometry. Figural representation was widespread, however the appearance of the narrative scene of Bahram Gur and Azadeh on metalwork is unprecedented. Three reasons could be attributed to this occurrence. First, the Seljuqs associated with the story of a heroic Persian King. The Seljuq military men decided to include the story of a heroic King on their metalwork as a resemblance to them. Bahram Gur is a ruler from the Sassanian period5. He is known for his hunting prowess, strength against wild animals, and military power. Second, oral traditions, and the widespread of the story of Bahram Gur facilitated the appearance of the narrative scenes on metalwork from this period. The traveling scholars, poets, artists were part of the Muslim culture, which enhanced exchange of knowledge and information. And the stories of Bahram Gur were widespread in Iran which triggered a high image production in the area6. Consequently, the oral traditions lead to the widespread of the stories of Persian Kings. Third, the appreciation of the Seljuqs of the Persian culture, may have triggered the rendering of the narrative scene of Bahram Gur and Azadeh on their metalwork. The Seljuqs were military commanders who came into Persia to defend territory7. The art produced under their rule reflected the culture of Persia. Moreover, the representation of Bahram Gur on their metalwork could indicate the appreciation of some rulers to the story of a heroic Persian Sassanian King.
Elaboración de Planes Locales de Desarrollo en la Comunidad Las Lajas, Santiago Tulantepec, Hidalgo.

Las teorías del desarrollo tienen una preocupación y origen desde los primeros economistas llamados clásicos, para tratar de explicar los diferentes niveles de desarrollo de los países, desde el mercantilismo, el capitalismo manufacturero del siglo XVIII ( Adam Smith, David Ricardo) y el desarrollo del capitalismo Industrial del siglo XIX (Carlos Marx, Walras, Jevons, Marshall,). En el siglo XX surgen interpretaciones del desarrollo, en los años 40 ́s y 50 ́s (Lewis,Harrod, Domar, Solow etc.) tratan de teorizar y de explicar esa dicotomía entre los países desarrollados y los subdesarrollados desde una visión analítica e histórica. La teoría convencional de la economía (neoclásica), ponía de modelo a los países industrializados. En los 90 ́s, Amartya Sen introduce el Índice de Desarrollo Humano (IDH) con nuevos indicadores y posteriormente el ambiental, las políticas públicas afrontan los diversos problemas de los países desarrollados, las economías denominadas emergentes y los menos desarrollados. En el siglo XXI la elaboración de planes y diagnósticos se convierten en un instrumento principal para detectar la problemática de las comunidades y orientar las acciones en una economía global.

The purpose of the research is to develop a territorial analysis to propose measurement tools for sustainable land management in river basin Coata region of Puno - Peru. The research design is exploratory. The hypothesis that guides the study suggests that this status quo has to do among other things, with both mistakes in reading the territory, as in the elaboration and implementation of rural land development proposals. This exercise culminates in a triangulation between diagnosis systems cultural, agricultural and forestry development, identifying measurement tools that are constantly applied in the basin such as the SWOT analysis, logical framework, exercises that contribute to setting indicators sustainability from a comprehensive and specific outlook for the basin, which is synthesized in the formulation of a proposed uses. This implies an adjustment to the planning, monitoring and evaluation for the territory, with formulation of rural territorial development indicators that consider elements of sustainability itself for the territory as part of the process of the basin development and collecting practices sustainable, aimed at improving the quality of life of the population.
Historia de dos ciudades, y de un santuario para animales: futuros multiespecie en el Antropoceno
Authors: Tavera Villegas Hugo
Published: March 2023

En este ensayo ofrezco una descripción de la manera en que el futuro es imaginado al interior de la literatura sobre los derechos de los animales, específicamente por autores que se ubican dentro del llamado giro político en la ética animal. En el Antropoceno, término con el que se designa a nuestra era geológica, caracterizada por la influencia de la especie humana sobre el sistema de la Tierra, el futuro parece haberse eclipsado, tanto así que este solo es para muchos concebible como catástrofe. A través de la exposición de diferentes imaginarios políticos multiespecie, concretizados en la construcción teórica de zoodemocracias del futuro, doy cuenta aquí de una emergente literatura sobre utopías políticas caracterizada por la crítica al excepcionalismo humano.
