The Microblades Cache from Upper Paleolithic Cultural Layer of the Strelka-1 Site in Krasnoyarsk
Authors: Barkov A. V. , Kolesnik A. V.
Published: September 2024

Observations. During the excavation of the multi-layered archeological site of Strelka-1 in 2021 a small cluster of microblades chipped off one core was found within Upper Paleolithic cultural layer. The cultural layer dated about 16 000 cal BP. 12 microblades were found tightly adjacent to each other in a kind of a “bunch”. It is possible that the blades originally were kept in an organic small “bag” or were tied with a strap together. The main part of the microblades conjoins back into two blocks of the initial core. Similar clusters of the stone pieces are described as caches that is purposely hidden values. The lithic industry relates to the Afontova culture which used microblades as insets for different composite tools made of organic materials. The set of the stone insets from cache matches to the term “tool kit”. There are the same tool kits in the Upper Paleolithic sites of the European part of Russia. A number of sites such as Kostenky-1 (in upper cultural layer), Avdeevo, Kamennaya Balka II etc. comprised “tool kits” consisting of stone blades placed into a cultural layer as a cache. Presumably such tool kits were the Stone Age huntersgatherers’ private property. The tool kits were made up shortly after the cleavage of a core.Conclusion. The authors of this article interpret microblade tool kits as a display of the non-utilitarian behavior of Upper Paleolithic man. This phenomenon within very remote territories and in genetically unrelated cultures reflects the general archetype of consciousness of primitive people.

Published: September 2024

Purpose. The study results of the storage pit no. 1791 for fish supplies from the Tartas-1 site are presented. This site is the basis for studying the Early Neolithic Barabinskaya culture. The aim is to reconstruct the peculiarities of functioning and chronology of pit no. 1791 investigated at the site Tartas-1.Results. During the investigation of the pit, it was discovered that upper layers were a later pit no. 1791 that was built on top of an older storage pit when it had ceased to function. In the bottom of this later pit, a horn of a large animal (probably a bison), a large fragment of a ceramic vessel, and a large accumulation of fish scales and gill coverings were found; in the older pit numerous almost rotted fish bones and an animal (probably dog) bone were found. Radiocarbon dating has been used to determine the chronological position of the pit no. 1791. Samples of bison horn fragments and dog bones, stratigraphically located at different depths, were used.Conclusions. The analysis confirmed the stratigraphic observations made earlier: the dates obtained chronologically place the pit in the Early Neolithic period, and they correlate with the dates obtained previously in laboratories in Germany and Russia, within the VII millennium BC, with a partial overlap to the VIII century BC. Radiocarbon dating confirmed the stratigraphic observations. We studied two Early Neolithic objects: an early fish storage pit and a late pit that sealed it. Few remains of fish bones and a dog bone were found in the fill and at the bottom of the early pit. The late pit contained a hoard of buffalo horns, ceramics, stone and clay tools, and fish scales.
The Saber of the Qing Empire: Peculiarities of Chronology and Morphology
Authors: Pastukhov A. M.
Published: September 2024

Purpose. The article describes the peculiarities of chronology and morphology of the saber of the Qing Dynasty. Additionally, it analyzes the design, system and techniques of decoration, as well as the materials used for the manufacture of the scabbard.Results. The total length of the saber is 88 cm including the length of the blade 70.8 cm. When in the scabbard, the length is 101.8 cm. The blade is made of Damascus steel in 18th century and the fittings of the hilt and scabbard are made of cooper alloy using the punch technique. Their surface is decorated with elaborated ornament representing playing human figures and clouds. The total style of fittings is fangshi but the material and technique applied are not characteristic for the genuine fittings of Qing 18th century sabers, they were obviously made in the end of Qing period imitating the high-Qing style. In general, the saber has the blade of Damascus steel made in 18th century mounted into the copper alloy fittings in fangshi style made in the late 19th – early 20th century.Conclusion. The saber is a rare survived sample of the high-quality blade made in 18th century with almost intact geometry, and fittings interesting in respect of techniques used and the plot of ornamentation, made in late 19th – early 20th century. As the piece of high-Qing period blade it could be regarded as the interesting sample of the art of highQing era swordsmiths and decorative art of the end of the imperial period in respect of fittings. Putting this saber into the scholar circulation gives the valuable material to the researchers for attribution of Qing edged weapons in museum and private collections.

Published: September 2024

Background Problems: Currently, there is still limited identification of nutritional intake, hormonal, and physical performance in adolescent athletes in Indonesia. Research Objectives: This study aims to identify anthropometric, nutritional intake, IGF-1 hormone level, and adolescent athletes’s performance. Methods: The research method used a cross-sectional study. A convenient sample of 58 athletes under Balai Pemusatan Pendidikan dan Latihan Pelajar. The research instrument used Bioelectrical Impedance Analysis (BIA), leg dynamometer, hand grip dynamometer, tape measure, height stature, SQ-FFQ Form, and body fat caliper. Blood samples were collected and tested by a professional laboratory. Data analysis techniques used Pearson’s test for normally distributed data and Spearman’s rank for non-normally distributed data. Findings and Results: The result of this study found a significant (p < 0.05) correlation between energy intake, anthropometric measurement of z score (BMI/Age), and endomorph score with an athlete’s muscle strength. We also found significant differences (p < 0.05) in macronutrient and micronutrient consumption in male and female athletes, and we also found significant differences in somatotype score and muscle strength in male and female athletes. Conclusion: We conclude that many athletes are not consuming the recommended levels of carbohydrates, fat, protein, and some micronutrients. We found a correlation between energy intake and fat intake with leg muscle strength. However, there was no correlation between IGF-1 hormone levels and athlete strength. Intake is thought to indirectly affect grip strength and leg strength.
Emergence of IT Implementation Consequences in Organizations: An Assemblage Approach
Authors: Sesay Abdul , Karahanna Elena , Boudreau Marie-Claude
Published: September 2024

Ex nihilo nihil fit—nothing comes from nothing—fundamentally challenges IS scholars to explain how a new behavior may emerge and evolve into a recognizable practice from an organization’s IT implementation processes. Prior research addressing this problem has ascribed consequences to a pre-existent macro-level structure or micro-level interactions. We examine this issue by conceptualizing the emergence of IT implementation consequences as a multi-phased process with analytically disaggregated phases. Using an assemblage lens, our theorizing draws on data from a multisite case study of Body-Worn Camera technology implementation in three municipal police organizations in the U.S. We identify three emergence phases—individuation, composition, and actualization—and develop a process model theorizing a path from material and expressive components to IT implementation consequences through cascading properties and capacities. Our model shows that the emergence of IT implementation consequences is non-linear, and involves feedback loops across multiple phases. In some instances, IT implementation consequences may emerge via negative feedback loops involving tweaks and course correction before converging into recognizable new practices. In other instances, they may fail or delay converging into recognizable practices. We also show how combining existing components and assemblages results in nesting assemblages at successively larger scales. This helps us to relativize the micro-macro relationship and explain both top-down and bottom-up emergence of IT implementation consequences.
Advancing Understanding of Scaling Health Information Infrastructures: Learning from EHR Initiatives in England
Authors: Klecun Ela , Kankanhalli Atreyi , Zhou Ya
Published: September 2024

Many countries are developing their health information infrastructures (HII), such as integrated electronic health records (EHRs), as a means to improve healthcare efficiency and effectiveness. However, efforts to build and scale up HII are fraught with challenges, as exemplified by the well-known case of the National Health Service (NHS) in England. Particularly, HII scaling initiatives give rise to tensions, such as across geographical boundaries of EHRs, which are often not effectively addressed in practice. At the same time, there have been calls for research on scaling IS through a practice perspective, which adds to the existing categorical analysis of scale. Thus motivated, we aim to conceptualize the scaling of HII, focusing on the tensions between scales, the practices to accomplish scaling, and their consequences for scaling outcomes. To do so, we undertake a case study of recent NHS efforts to integrate EHRs in England, where we analyze these scalar concepts and their inter-relationships. Through our study, we further develop the notion that scaling not only involves increasing the scale of IS, but entails constructing and reconstructing scales. We also offer theoretical contributions by conceptualizing the range of scalar tensions and practices, their interplay, and influences on HII scaling outcomes. Tensions that we identify as associated with different scale boundaries (organizational, spatial, and technological), extend those recognized in prior research. Furthermore, we uncover scalar practices of joining and differentiating, adding to the governance and architectural approaches for HII scaling examined in past work. Through deepening the understanding of HII scaling, we generate insights for practitioners by highlighting scalar tensions and practices that could address the tensions under different conditions. Overall, we draw attention to scaling phenomena as being integral to the development of HII and introduce a new vocabulary for thinking about HII scaling.
When Algorithms Delegate to Humans: Exploring Human-Algorithm Interaction at Uber
Authors: Stelmaszak Marta , Möhlmann Mareike , Sørensen Carsten
Published: September 2024

Algorithms are increasingly seen as capable of autonomously initiating and managing interactions with humans—for example, through delegating the rights and responsibilities for successful outcomes of shared tasks without human intervention. While research into such interactions primarily focuses on dyadic configurations, complex settings where multiple agents work together have become a nexus of more nuanced interactions that go beyond the dyad. This paper explores such interactions through the lens of delegation by investigating how many algorithms delegate to many humans in a multi-agent setting. Analyzing patent data and interviews with drivers and passengers, we unpack delegation in the context of the ride-hailing application Uber. We theorize distributed delegation as a construct capturing collective hybrid appraisal, collective hybrid distribution, and collective hybrid coordination, in which a collective of algorithms delegates by drawing on inputs from multiple human agents. Our findings highlight that distributed delegation is collective, hybrid, and relational by nature, and demonstrate the extent to which human inputs are necessary for collectives of algorithms to exercise the capacity to delegate. Distributed delegation as a continuum of algorithmic and human involvement poses a challenge for recent theories suggesting the unprecedented autonomy of algorithms from humans.
Self-Organization and Governance in Digital Platform Ecosystems: An Information Ecology Approach
Authors: Engert Martin , Hein Andreas , Maruping Likoebe M. , Thatcher Jason Bennett , Krcmar Helmut
Published: September 2024

This research investigates the interplay of top-down control and bottom-up self-organization within digital platform ecosystems (DPEs), focusing on the formation and management of complementor coalitions. Although these coalitions can increase a DPE’s generativity, they can also threaten its integrity. We investigate this tension by employing information ecology (IE) theory, which allows us to examine complementor coalitions as holons that navigate between self-assertiveness and integration within the structural hierarchies of DPEs. Utilizing an inductive, embedded case-study approach, we analyze the interplay between top-down control exerted by platform owners and the bottom-up self-organization of complementors in two enterprise software platform ecosystems. Our findings identify three distinct interaction modes—mandated, supported, and autonomous self-organization—each presenting hierarchical trade-offs between platform owner control and complementor autonomy. Our findings extend the prevalent owner-centric theory of platform governance by highlighting the significant impact of bottom-up self-organization on the governance and evolution of DPEs. We propose an integrated theory that accommodates these new dynamics, suggesting soft power as an effective governance mechanism. This study contributes to a deeper understanding of the complexities in governing DPEs and offers practical insights for managing top-down control and bottom-up self-organization in the evolving landscape of enterprise software DPEs.

La zone sur laquelle porte notre contribution est localisée dans la steppe sud Algéroise (Algérie). Cette recherche est consacrée à l’analyse de la diversité floristique dans la région de Djelfa. L'étude de la végétaion de notre zone d'étude, a permis de discriminer sept groupements végétaux distincts sur le plan floristique et physionomique. L’analyse de la phytodiversité globale, a permis de recenser 170 taxons appartenant à 34 familles et 111 genres. Asteraceae, Poaceae, Fabaceae, Brassicaceae et Cistaceae sont les familles les plus représentées avec environ 59% des espèces. Le spectre biogéographique global indique la dominance des espèces méditerranéennes avec 80 espèces soit 47 % des taxons dénombrés. 27 espèces endémiques soit 16 % ont été identifiées, dont 16 espèces le sont d’Afrique du Nord. L'analyse des types biologiques a montré la dominance des thérophytes qui représentent 85 taxa soit 50 % par rapport aux autres formes de vie. L’analyse de la diversité floristique par l’utilisation de l’indice de Shannon-Weaver (H’) dans les unités de végétation (forêt, matorral, pelouse, steppe à alfa, steppe présaharienne), a montré une diversité moyenne à faible qui oscille entre 3,34, dans les formations végétales de la steppe à alfa, et 2,40 dans la steppe présaharienne dégradée. Ces résultats sont confirmés par l’indice de Pielou (E) avec respectivement 0,55 et 0,39 dans les deux formations.
A human capital simulation model in innovation projects
Authors: Бекетов С.М. , Поспелов К.Н. , Редько С.Г.
Published: September 2024

Рассмотрены основные аспекты концепций человеческого капитала, инновационных проектов и имитационного моделирования, на основе чего предложена имитационная модель, описывающая роль человеческого капитала в инновационных проектах. Разработанная модель высокого уровня абстракции создана для исследования роли социального компонента в организационной структуре инновационного проекта в общем контексте (на уровне отрасли, предприятия, части предприятия) и рассматривается прежде всего как инструмент для отслеживания динамики проектов с учетом состояния человеческого капитала системы. Модель состоит из двух основных частей: базовой имитационной модели, выполненной на языке системной динамики, и агентного компонента модели, описывающего динамику человеческого капитала. Модель представляет собой концептуальный инструмент, требующий калибровки и доработки для применения к конкретной организации.

The main aspects of three concepts––human capital, innovation projects, and simulation modeling––are considered, and a simulation model is proposed to describe the role of human capital in innovation projects. This high-level abstraction model is intended to study the role of the social component in the organizational structure of an innovation project in a general context (at the level of an economic sector, an enterprise, or part of an enterprise). It is treated primarily as a tool for tracking the dynamics of projects considering the state of human capital of the system. The model consists of two main components, namely, a basic simulation model in system dynamics terms and an agent-based component of the model describing human capital dynamics. The model is a conceptual tool that requires calibration and refinement when being implemented in a particular organization.
A LOCAL PATH PLANNING ALGORITHM FOR AVOIDING OBSTACLES IN THE FRENET FRAME
Authors: Макаров М.И.
Published: September 2024

Представлен алгоритм локального планирования пути в системе координат дорожного полотна. Он основан на варьировании точек исходной траектории с применением метода потенциального поля и обеспечения гладкости получаемого пути относительно новой системы координат. Реализация алгоритма основывается на решении задачи минимизации целевого функционала. Рассматривается решение задачи применительно к планированию пути беспилотной транспортной платформы, для чего требуется изменять участки заранее подготовленной гладкой траектории движения транспортного средства в режиме реального времени с учетом возникающих препятствий и с сохранением гладкости. Использование новой системы координат дает преимущество во времени выполнения алгоритма по сравнению с его работой в декартовой системе координат. Алгоритм реализован на языке Python. Выделение горизонта планирования позволяет сочетать предложенный подход с различными алгоритмами следования по пути, которые сами по себе не реализуют методы обхода препятствий. Численное моделирование выполнено для характерных примеров, по которым можно оценить эффективность предложенного алгоритма.

This paper presents a local path planning algorithm in the coordinate system of the roadbed. The algorithm is based on varying initial trajectory points using the potential field method and ensuring the smooth resulting path in a new coordinate system. This algorithm is executed by minimizing an objective functional. The problem is solved with application to path planning for an unmanned transport platform: it is necessary to change the vehicle’s global smooth trajectory points in real time while maintaining smoothness and avoiding emerging obstacles. Compared to the Cartesian coordinate system, the new coordinate system is advantageous in terms of the execution time of the algorithm. The algorithm is implemented in Python. With a planning horizon being specified, this approach can be combined with various path-following algorithms that have no obstacle avoidance methods. Computer simulation results are provided to demonstrate the effectiveness of the proposed algorithm.

Аннотация: Данная статья актуальна, так как процессы слияния и поглощения в период санкций и ухода с российского рынка иностранных компаний дают возможность развития новых процессов в данном направлении.  В статье анализируются процессы слияния и поглощения на основе российской практики.  Показаны изменения данных процессов в связи с вводимыми санкциями и влияния на них внешнеполитической обстановки. Авторы затрагивают вопросы роли государства в процессах слияния и поглощения, вызванные новой геополитической обстановкой и положением на российском товарном рынке. Авторами проведен анализ данных процессов в 2021 году и особенности M&A в первой половине 2022 года. В работе рассмотрена роль государства на рынке слияния и поглощения. Как правило она заключается в организации функционирования правовых институтов, арбитражных судов, а также принятии антимонопольных актов. Государство помимо законодательной поддержки и контроля само может выступать актором на рынке слияния и поглощения. Поддержка государства данных процессов в последние месяцы очевидна. Для эффективного функционирования рынка слияния и поглощения необходимо регулирование через взаимодействия спроса и предложения, а также создание государством правовой базы для формирования и поддержания институтов, координирующих данные процессы.

Negara Indonesia merupakan salah satu negara agrikultur, di mana bidang pertanian berperan penting dalam menjaga keberlangsungan hidup. Hal ini dikarenakan, sebagian besar masyarakat Indonesia menggunakan beras sebagai bahan pangan pokok mereka. Sedangkan ketersedian bahan pangan pokok masyarakat sudah berkurang, karena adanya alih fungsi lahan-lahan pertanian menjadi perumahan, industry, dan lain-lain. Bukan hanya itu saja, permasalahan lain yang dapat menurunkan ketersediaan bahan pangan yaitu seperti, kondisi iklim atau cuaca, system pengairan, serangan hama dan masih banyak lagi permasalahan yang dapat mengakibatkan panen menjadi kurang maksimal. Penggunaan teknologi dalam bidang pertanian seharusnya menjadi lebih mudah dan membantu para petani dalam mendeteksi penyakit yang menyerang daun padi. Karena itu, deteksi dan klasifikasi hama pada daun padi perlu dilakukan untuk mengevaluasi akurasi, presisi, dan recall menggunakan perhitungan matriks kebingungan (confusion matrix) dengan menerapkan algoritma K-Nearest Neighbors (KNN). Dari hasil klasifikasi tersebut menghasilkan nilai akhir akurasi paling tinggi yaitu sebesar 73% pada jarak piksel (d) yaitu 5 dan nilai tetangga (k) yaitu 3 pada offset 0°. Hal ini menunjukkan bahwa algoritma KNN cukup baik dalam melakukan klasifikasi.

Published: September 2024

Malnutrition is still a national issue that affects many regions in Indonesia. The use of the Kartu Menuju Sehat (KMS) is considered less than optimal because of frequent recording errors due to the loss of the card, making it impossible to properly monitor the nutritional status of toddlers. In addition, people, especially parents, want to know whether their toddler's diet is adequate or not. Based on these problems, an application is needed to determine the nutritional status of toddlers. This research is important to assist medical personnel in assessing the nutritional status of toddlers and can be relied upon for accuracy through an expert system application. This research aims to develop an expert system application that utilizes the Fuzzy Mamdani method to identify the nutritional status of toddlers based on weight, age, height, and arm circumference parameters. The stages in this research include identifying parameters that affect nutritional status through sources of expertise from doctors, determining sets and rules in the fuzzy method, system implementation, system evaluation, and optimization. The results stated that the Fuzzy Mamdani method has an accuracy value of 90.2% in detecting the nutritional status of toddlers. The acceptance test of the application display assessment resulted in 92.5%, the ease of use of the application was 85.83%, and system analysis resulted in 90.83%.

Published: September 2024

The limited availability of synthetic techniques and methods, coupled with the sensitivity of the oxazole ring, has restricted the use of ethynyl-substituted oxazoles in drug design, despite their potential advantages. In this study, we present our extensive experience in oxazole chemistry through a comprehensive analysis of the oxazole core’s tolerance to various reaction conditions for selective modifications. Additionally, we aimed to optimize synthetic protocols to develop efficient methods scalable to multigram quantities in a single run. We also sought to identify mild, tolerant approaches to address the instability of the oxazole ring and manage potential side reactions. Our work led to the development of an efficient approach for performing click reactions on ethynyl heterocycles, resulting in excellent yields and a straightforward purification process. This opens up a largely unexplored space for incorporating small molecule oxazoles into drug targets via click reactions with various azides. These findings could significantly advance oxazole chemistry and their integration into drug development programs.

Solid polymer electrolytes are an exciting solution for safe and stable solid lithium electrode battery systems but are hindered by low ionic conductivity and low lithium transference. All-atom molecular dynamics simulation has become an invaluable tool to probe lithium diffusion mechanisms and accelerate the discovery of promising polymer chemistries. Because of their low computational cost and despite their approximate nature, only classical interatomic potentials can access the time and length scales for appropriate statistics of polymer kinetics. Machine learning (ML) potentials trained end-to-end on ab initio data have proven more accurate but cannot be scaled to the necessary time- and length- scales yet. Historical approaches to parameterize classical force fields have been incremental, reliant on a manual combination of top-down and bottom-up fitting, and are often paywalled and hard to reproduce. We introduce a computational learning workflow to predict classical interatomic potential parameters using quantum mechanical computations as training data that combines the automation and end-to-end fitting of ML with traditional class 1 and class 2 functional forms. The fitting strategy produced potentials whose simulations improved the accuracy of lithium coordination environments, diffusivities, and conductivities relative to experimental approaches when compared to both naive and hand-tuned parameters for liquid and solid organic electrolyte systems. We show that chemistry-informed regularization is necessary to constrain predicted parameters in order to reproduce experimental solvation and kinetic properties. Finally, we explore the limitations of non-polarizable, fixed point-charge schemes in describing electrolyte anions and compare the effects of two alternative schemes to fit point-charge distributions. The two strategies result in distinct lithium coordination mechanisms and highlight that closest parity to DFT forces and energies does not correlate to correct trends with lithium salt concentration in kinetic and solvation properties for fixed-point-charge classical interatomic potentials.
q-Gaussian and q-BWF functions for the deconvolution of Raman and infrared spectra of Calcite
Authors: Sparavigna Amelia Carolina
Published: September 2024

Here we consider calcite and its spectra (Raman and infrared) that we can find in the RRUFF database. We apply q-Gaussian and q-BWF functions to decompose the spectra. The q-Gaussian functions had been derived in the framework of Tsallis analysis of entropy. Their use for Raman spectroscopy has been proposed by Sparavigna, 2023. The q-BWF functions have been defined by Sparavigna, 2023, to generalize the BWF (Breit-Wigner-Fano) functions, and proposed for fitting to asymmetric peaks in Raman spectroscopy. Besides examples of decompositions of RRUFF spectra, a review of literature about calcite is given. We will also add an appendix about the Raman spectra of calcite recorded by R. S. Krishnan (1945), by means of the F. Rasetti technique (1932) which was using the λ2536.5 mercury resonance radiation. As we can see, Krishnan succeeded to record the second order components of the spectrum.

Published: September 2024

The future food security and hidden hunger are the major challenges which lead the developing countries for the exploration of wild edibles. Wild edibles have also been explored for their nutritional values which can potentially contribute to solving the issues such as malnutrition and livelihood in developing and rural communities of various parts of the world. This is first study to evaluate the nutritional values and phytochemical screening of semiarid populations of Marsilea spp. The nutritional analysis reveals carbohydrate (0.63 %), protein (4.20 %), fat (5.0 %), dietary fiber (8.6 %) and mineral content. the study also attempts various antioxidant assays such as DPPH, FRAP, ABTS, CUPRAC and PMA. The results show Marsilea is a very rich source of nutrition and minerals. It may help in livelihood development in developing and poor countries. This fern can also be utilized for fortification and developing the cultivation practice of Marsilea.

Published: September 2024

Mitochondria exhibit a close interplay between their structure and function. Understanding this intricate relationship requires advanced imaging techniques that can capture the dynamic nature of mitochondria and their impact on cellular processes. However, much of the work on mitochondrial dynamics has been performed in single celled organisms or in vitro cell culture. Here, we introduce novel genetic tools for live imaging of mitochondrial morphology in the nematodeCaenorhabditis elegans, addressing a pressing need for advanced techniques in studying organelle dynamics within live intact multicellular organisms. Through a comprehensive analysis, we directly compare our tools with existing methods, demonstrating their advantages for visualizing mitochondrial morphology and contrasting their impact on organismal physiology. We reveal limitations of conventional techniques, whereas showcasing the utility and versatility of our approaches, including endogenous CRISPR tags and ectopic labeling. By providing a guide for selecting the most suitable tools based on experimental goals, our work advances mitochondrial research inC. elegansand enhances the strategic integration of diverse imaging modalities for a holistic understanding of organelle dynamics in living organisms.

Published: September 2024

O presente artigo trata da evolução do desmatamento no período de 2000 a 2009 no município de Brasnorte/MT, incluindo o uso e ocupação nas Terras Indígenas. O mapeamento foi determinado através da interpretação visual das áreas desmatadas nas imagens de satélite Landsat TM5, georreferenciadas, na resolução de 30m, utilizando software ArcGis. Obtiveram-se mapas de desmatamento da área total do município e de cada reserva indígena em cada período mencionado. Observou-se que o desmatamento está atrelado ao avanço da fronteira agrícola e das áreas de pastagens, além da extração da madeira para fins comerciais. Para o ano de 2000 a área total do município apresentava um uso de 29,48% e no final de 2009 de 46,46% adentrando Terras Indígenas. Com uma maior fiscalização e controle do desmatamento houve o processo de consolidação da cultura da soja e redução do extrativismo vegetal, que no início do período era a principal economia do município.
REFLEXÕES SOBRE PLANEJAMENTO URBANO EM UBERLÂNDIA (MG): A ABORDAGEM DO PLANO DIRETOR ATUAL PARA A MOBILIDADE URBANA
Authors: Gomes da Silva João Paulo , Gumiero Cleps Geisa Daise
Published: September 2024

A intensa dinâmica urbana de Uberlândia trouxe consigo uma série de problemas como o crescimento excessivamente horizontalizado do sítio urbano, com ocupação de áreas desprovidas de infraestrutura básica, especulação imobiliária, além de problemas relacionados à mobilidade. Tais problemas exigiram do poder público municipal a elaboração de planos e/ou instrumentos urbanísticos que pudessem conter o crescimento desordenado da cidade. Desde então, foram elaborados diversos planos urbanísticos, de intervenções no sistema viário, legislações de uso e ocupação do solo e, por fim, os Planos Diretores. Deste modo, este trabalho tem por objetivo apresentar e analisar as diretrizes referentes à mobilidade urbana contidas no atual plano diretor da cidade de Uberlândia, aprovado em 2006. A temática é relevante visto que a melhoria da mobilidade urbana é um meio de se garantir um crescimento urbano sustentável e uma apropriação mais justa e democrática dos espaços públicos, colaborando para a consolidação de uma boa qualidade de vida na cidade de Uberlândia-MG.
