Collision Avoidance for a Car-like Mobile Robots using Deep Reinforcement Learning
Authors:   Department of Human Intelligence and Robot Engineering, Sangmyung University, South Korea, Yeom Kiwon
Published: November 2021

—The applications of mobile robots are more and more diverse and extensive. The motion planning of the mobile robots should be considered in aspect of effectiveness of the navigation, and collision-free motion is essential for mobile robots. In addition, dynamic path planning of unknown environment has always been a challenge for mobile robots. Aiming at navigation problems, this paper proposes a Deep Reinforcement Learning (DRL) based path planning algorithm which can navigate nonholonomic car-like mobile robots in an unknown dynamic environment. The output of the learned network are the robot’s translational and angular velocities for the next time step. The method combines path planning on a 2D grid with reinforcement learning and does not need any supervision. The experiments illustrate that our trained policy can be applied to solve complex navigation tasks. Furthermore, we compare the performance of our learned controller to the popular approaches.

This article deals with a diagnostic approach based on a predictive / conditional maintenance approach of a hydroelectric group. The technique used is based on the spectral analysis of the vibration signals, as well as on the orbital analysis of the bearings displacements. To do this, test protocols in different operating regimes are carried out, based on the collection of data measured according to the multisensor approach, the aim of which is to identify the predominant faults. The positions of the sensors are placed as close as possible to the bearings on the rigid structure of the hydroelectric group in accordance with the recommendations of standard ISO 10816-5. The evaluation approach is based on the analysis of the amplitudes of the vibration speeds, the aim of which is to identify the type of faults, as well as on the bearing displacement indicators in order to classify them in the pre-established zones according to thresholds recommended by the Standard. Therefore, a recommended tuning intervention can be planned in order to restore the unit to its proper operating condition, the aim of which is to increase its service life and improve fuel efficiency.

Those who use convex or concave lenses should use sunglasses made from regular spectacle lenses. In this case, it uses a surface coating to block UV rays, so it is relatively vulnerable to UV protection. To this end, we developed a spectacle lens that can completely block ultraviolet light and suppress blue light by using a monomer that completely blocks the area below 410 nm and has a sunglasses function through photochromic function. A spectacle lens with photochromic, polarization and UV blocking functions was developed using a monomer with a high refractive index of 1.67. In the photochromic property, a recovery time of 2 minutes for light reaction and 5 minutes for dark reaction was obtained. Five layers of anti-reflection coating were applied to the surface of the lens to reduce the transmittance in the visible light region to 0.1 or less. ITO was applied to give an electromagnetic wave shielding function, and the thickness and conductivity of ITO were proportional to the result. The blue light emitted from the LED is reduced by more than 30% to reduce eye fatigue. UV rays were completely blocked below 410 nm.

Microesferas de ácido poliláctico marcadas con 166Ho. Una alternativa frente a las de 90Y en el tratamiento del carcinoma hepático mediante radioembolización
Authors: Pérez-Doñate Alejandro , Pérez-Giménez Facundo , Romero-Otero Mónica , Pérez-Doñate Virginia , Castillo-Garit Juan Alberto
Published: November 2021

Los tumores hepáticos constituyen un importante problema de salud a nivel mundial que en multitud de ocasiones va asociado a patologías previas y factores de riesgo como las hepatitis víricas B y C, el consumo excesivo de alcohol y el aumento de casos de esteatohepatitis no alcohólica, cada vez más relevante en los países industrializados.En hepatocarcinomas no susceptibles de resección quirúrgica, la braquiterapia se está mostrando muy eficaz frente a la quimioterapia sistémica y transarterial, por lo que se desarrollan nuevos tratamientos locorregionales mínimamente invasivos y con menor toxicidad.La radioembolización hepática es una forma de braquiterapia consistente en la administración por vía arterial de microesferas marcadas con radionucleidos emisores beta negativos que en el tejido hepático tienen una escasa penetración, lo que permite la administración de dosis elevadas que provoquen daño celular en el tejido tumoral, de manera que se evita la irradiación de tejido sano contiguo.Entre las microesferas más utilizadas se encuentran las de resina y/o vidrio marcadas con 90Y, aunque actualmente se está incrementando el uso de las de 166Ho sobre matriz biodegradable de ácido poli-L-láctico, los motivos principales residen en las características de este radionucleido, como son la emisión beta de menor energía, el periodo de semidesintegración más corto y presentar, además, emisión de fotones gamma, lo que permite su seguimiento gammagráfico. Asimismo, es un elemento paramagnético, por lo que se puede detectar mediante resonancia magnética, lo que facilita la simulación previa al tratamiento y el seguimiento posterior de este.

Published: November 2021

La malaria es una enfermedad parasitaria causada por protozoos del género Plasmodium y transmitida por vectores del género Anopheles. En 2019 esta enfermedad se cobró la vida de más de 400.000 personas, de las cuales un 94 % se concentraban en la región de África. Uno de los principales problemas en el control de la malaria es la aparición de resistencias frente a los diferentes fármacos que existen, es por ello que es necesario el desarrollo de alternativas antimaláricas eficaces. En este estudio se ha aplicado la topología molecular a una serie de compuestos análogos de la 4-anilinoquinolina con actividad inhibitoria de la proliferación de 3 cepas de Plasmodium falciparum, una sensible a la cloroquina (D6) y dos resistentes (W2 y C235); para así desarrollar un modelo de relación cuantitativa estructura-actividad QSAR que permita predecir la actividad de los compuestos frente a cada una de ellas. Utilizando el análisis lineal discriminante se seleccionaron tres funciones que clasificaron correctamente el 87 % de los compuestos analizados en la cepa D6, en la W2 y en la C235, respectivamente. Para la validación del modelo se empleó un test interno del tipo leave some out para cada una de las funciones. Por último, se aplicó el modelo en la búsqueda de nuevos compuestos antimaláricos potencialmente activos frente a las tres cepas.
Desechos de vinificación como inhibidores de biopelículas de Staphylococcus aureus
Authors: Viola Carolina María , Cartagena Elena , Arena Mario Eduardo
Published: November 2021

Staphylococcus aureus es un patógeno conocido que forma biopelículas en una amplia variedad de entornos y representa un riesgo severo de contaminación de los alimentos. El presente estudio se centró en la determinación de las capacidades antibiofilm de extractos de orujo procedentes de diferentes varietales de diferentes polaridades, procedentes de Cafayate, Argentina, frente a dos cepas de S. aureus. Se utilizaron orujos de tres varietales regionales (Bonarda, Tannat y Malbec) para inhibir la formación de biofilm (BF) o tratar una biopelícula formada. Se realizaron extracciones con solventes de polaridad creciente (cloroformo, acetato de etilo y etanol) y se enfrentaron 10 y 100 µg/mL de extractos a las cepas de S. aureus ATCC 6538 y LVP63. Los extractos acetato de etilo y etanólicos de orujo del varietal Tannat fueron los más efectivos para disminuir la formación de BF en S. aureus sin afectar el crecimiento planctónico. Respecto a los efectos sobre la biopelícula preformada, los extractos de los varietales Malbec y Tannat disminuyeron la actividad metabólica hasta un 70% y los extractos polares de Tannat y la mezcla de orujos disgregaron hasta un 65% el BF preformado por ambas cepas S. aureus. Por lo tanto, la reutilización de estos desechos agroindustriales se plantea como una alternativa natural para combatir bacterias patógenas en la industria alimentaria, disminuyendo el impacto de estos residuos agroindustriales en el ambiente y convirtiendo a estos desechos en un bioproducto, económicamente, rentable.

Published: November 2021

Lipid oxidation is the reaction responsible for food degradation, to solve this problem the agri-food industry uses antioxidants, preservatives and chemical stabilizers. Currently there is an increasingly strong demand for healthier eating, because of this, the industry is increasingly interested in replacing chemical compounds with natural products of equal or greater effectiveness. This project studies oxidative stability in margarines of different composition, both qualitative and quantitative, when independently adding dehydrated material from a fungus (Lentinula edodes) and a seaweed (Chondrus crispus), which are characterized for having antioxidant activity. To achieve this, Rancimat equipment was used at different temperatures: 110 ºC, 120 ºC, 130 ºC and 140 ºC ± 1.6 ºC. comparing treated margarine samples with their respective controls. Results varied depending on the temperatures used, the composition of margarines and the natural antioxidants added. The results show that the margarine with a lower proportion in unsaturated fatty acids, and especially in polyunsaturated fatty acids, have greater oxidative stability and it increases to a greater degree when the fungus is added with respect to the addition of seaweed.

Published: November 2021

La enfermedad de Chagas es una antropozoonosis parasitaria de transmisión mayoritariamente vectorial. Si bien afecta principalmente a América, constituye una de las mayores enfermedades desatendidas a nivel mundial. Solamente dos fármacos con un alto grado de toxicidad se encuentran disponibles para su tratamiento, por lo que es preciso aunar esfuerzos en pos del desarrollo de nuevas drogas antitripanosomales eficaces y con escasos efectos adversos. En este estudio, se aplicó la topología molecular para el desarrollo de un modelo QSAR capaz de predecir la actividad citotóxica antitripanosomal de un grupo de 39 compuestos. El modelo desarrollado mediante análisis lineal discriminante permitió clasificar correctamente al 93,3 % de los compuestos activos estudiados. Para la predicción de la potencia antitripanosomal se empleó un análisis de regresión multilineal, que fue capaz de explicar el 90,8 % de la varianza. Ambos análisis fueron validados mediante un test interno de tipo “leave some out”. Se aplicó el modelo obtenido a nuevos compuestos, destacándose ocho moléculas potencialmente activas que podrán ser utilizadas en futuros ensayos preclínicos.

Published: November 2021

Las queratosis actínicas son lesiones cutáneas preneoplásicas frecuentes causadas por una exposición crónica a las radiaciones solares.  La obtención  de modelos animales que contribuyan a comprender los mecanismos implicados en esta patología y a evaluar nuevas terapias farmacológicas resulta de gran interés para la comunidad científica.  Se desarrolló un biomodelo de queratosis actínica en ratones Balb/c, empleando como inductor la radiación UVA. Se aplicaron dos esquemas de irradiación: Grupo I, expuesto a tres sesiones diarias de radiación de 2h y Grupo II, dos sesiones diarias de 4h, con igual tiempo de receso entre sesiones y durante un período de 14 días. Se evaluaron parámetros macroscópicos y microscópicos, y la frecuencia de aparición de micronúcleos en sangre periférica. Los animales correspondientes al Grupo I no mostraron lesiones mascroscópicas y microscópicamente evidenciaron una leve acantosis con ausencia de displasia; mientras que en los animales del Grupo II se observaron lesiones macroscópicas que se correlacionan histopatológicamente con la presencia de una queratosis actínica. La frecuencia de micronúcleos obtenida en el Grupo II fue significativamente superior a la formación de micronúcleos espontáneos en el Grupo Control. El biomodelo experimental de queratosis actínica obtenido reproduce el efecto de las radiaciones ultravioletas sobre la piel.
Qualitative Insider Research in a Government Institution: Reflections on a Study of Policy Capacity
Authors: Cameron Bobby Thomas
Published: November 2021

Embarking on a qualitative Ph.D. research project in public administration is often daunting for novice researchers. For those students who consider adopting an emic or insider approach for their research, the ethical, methodological, and analytical challenges that lay ahead may seem insurmountable at times. In this article, I reflect on my experience as a Ph.D. student completing qualitative research with my colleagues to study policy capacity in a provincial government in Canada. I review how I constructed an ethical framework by integrating policy from Research Ethics Boards and government. Throughout the article, I deal primarily with ethical considerations and the personal and professional tensions associated with insider research. In addition to providing an overview of the literature on insider and emic research, I present ethical protocols that student-practitioners in other settings should consider when completing academic research with their colleagues in government institutions. Overall, the risks one must mitigate and minimize when completing insider research in government institutions are not substantially different from insider research in private institutions. While insider approaches in the study of public administration are not without their unique challenges, they do offer great potential in broadening and deepening emic knowledge of public administration practice.

Con el objetivo de contribuir con información relevante sobre el impacto de la tasa de cambio sobre el comportamiento de los flujos comerciales de maíz, en un contexto de subsidios a la producción, además de generar información relevante para la toma de decisiones de política económica. Para lo cual se analizó un modelo de maximización de la utilidad esperada y se estimó una función de demanda por importaciones de maíz a partir de un análisis de cointegración y un modelo vector de corrección de error (VCE). Los resultados mostraron que los cambios de la tasa de cambio real tienen efecto positivo sobre los flujos comerciales, en tanto que la volatilidad de la tasa de cambio ejerce un efecto negativo sobre dichos flujos. Los resultados de la prueba de hipótesis indicaron que tanto los cambios en la tasa de cambio real como la volatilidad tienen un efecto significativo sobre los flujos de comercio de maíz entre México y Estados Unidos.
The Legal Protection for Female Workers in the Perspective of Islamic Law and Law No. 11 Year 2020 on Job Creation
Authors: Koto Ismail , Hanifah Ida
Published: November 2021

On Monday, 5 October 2020, the Draft Law on Job Creation was ratified by the House of Representatives of the Republic of Indonesia and the manuscript was signed by the government on November 3, 2020. Therefore, since November 3, 2020, the Draft Law on Job Creation promulgated in Law Number 11 Year 2020 on Job Creation. Based on the existing official text, the researcher intended to compare the rights of female workers as regulated in Law Number 13 of 2003 on Manpower with Law Number 11 of 2020 on Job Creation. The research method used in this study was a normative juridical research, with a statutory and conceptual approach, descriptive analytical research specifications, data collection by literature study, and qualitative data analysis. The protection of female workers as referred to in the previous labor law was still valid and was not discussed at all in Law Number 11 of 2020 on Job Creation. Therefore, it could be ascertained that the refusal of workers during the process of the Draft Law on Job Creation is wrong. The article which was amended related to the protection of female workers did not change the substance of the protection of female workers as previously regulated through Law Number 13 Year 2003 on Manpower. The Qur'an has been explained that people need to provide special rights for female workers. Explicitly, there is no verses in the Qur'an that mentioned the word 'special rights for female workers'. However, implicitly, there were general arguments based on the verses in the Qur'an that could be used as a basis for granting this right. Some of the special rights of female workers were implicitly communicated in Islamic teachings.

Authors:   Ministry of Health, Sri Lanka, Karunapema R.P.P.
Published: November 2021

Background: Many health problems encountered today arising from consumption of unsafe food. Contamination of food and feeds arising from naturally occurring toxicants, microbiological contaminants, chemical contaminants such as additives used above the permitted levels, pesticide and veterinary residues in food or as toxic components from food processing could have deleterious effects in humans and animals. Food control measures are critical in fostering food safety management of a nation. Methods: In depth review of the existing legislation on food safety and hygiene and the food control system was done. International literature and reports were reviewed to compare the current global situation and the Sri Lankan situation. In depth interviews were conducted among the Public Health Inspectors who comprise the majority of authorized officers Results: The food control legislation which was enacted in 1980 has been amended only twice in 1991 and 2011. There are over 50 Regulations brough in time to time under the Food Act of 1980. The food control system is mainly centralized and the implementation is done mainly at the level of the Medical Officer of Health (MOH). Many provisions of the legislation are outdated and needs revisions. The perception of the Public Health Inspectors reveled that a vast majority are not satisfied with the current food control system and are the opinion that the improvements should be made in all areas related to the food control system. Conclusion: The food control system in Sri Lanka should be revisited and be improved and updated to be in line with the current global trends. The capacities of the analytical system as well as the authorized officers should be improved in order to ensure effective implementation of the food control system.

En este caso, lo que aquí se presenta, es la parte conceptual de una investigación que hurga el movimiento estudiantil de 1968. A 50 años de ocurrido, nos hemos dado a la tarea de explorar distintas expresiones que se encuentran en el mismo 68, como los escritos por parte de su órgano de dirección, el Consejo Nacional de Huelga, y sus volantes, así como lo que la prensa y otros sectores, como los empresarios, que en su momento se manifestaron. Explora- mos, asimismo, sobre los escritos que varios de los dirigentes posteriormente publicaron. Reconstruimos, a partir del análisis de los principales periódicos de la época y en años recientes, cómo se ha desarrollado ese discurso sobre los movimientos de oposición. Igualmente, hemos entrevistado a participantes de aquel entonces y a quienes en la actualidad de alguna manera se vinculan a las manifestaciones que conmemoran el movimiento de 1968. Representaciones sociales de los actuales jóvenes, memoria colectiva de los participantes de entonces y mentalidades sobre el quiebre del orden autoritario de un sistema político, social y cultural, que se enquistó en distintas instituciones, como las universidades y las familias. Eso forma parte de un segundo momento de la actual investigación. En este primer escrito, proponemos un marco de referencia e interpretación de una investigación empírica en proceso.

Published: November 2021

The goal of investigation was assessment of environmental impact and economic efficiency of composite briquette production on the base of peat and renewable biomass. Biomass for composite briquettes was obtained from straw (cereal crops and rape) and wood residues (sawdust, chips) Experimental composite briquette were produced from the mixture of peat and biomass in relation to – 25 : 75, 50 : 50, 75 : 25. The technological cards of biomass feedstock production for 6 variants were developed. Technological cards were used for calculation of emission into the atmosphere during life cycle of biomass production and prime cost of biomass. The lowest volume of gas (SO2, NOx, CO2)

and particulate matter (PM) emission was installed for biomass production from the sawdust. The highest volume of

emission was installed for production of biomass from the straw with pressing it in standard bale. The volume of CO2

emission for the sawdust production was 6 kg per ton of biomass and for the standard bale of straw was 19 kg per ton of

biomass. Prime cost of sawdust production (lowest) was 11 belarusian rubles per ton of biomass, for the wood chips was 19 rubles per ton and for the straw varied from 26 to 33 rubles per ton in depend of technology. It was installed that

growth of biomass rate in composite briquette had a good influence on number of basic fuel characteristics (contents of

ash, sulfur and moisture). The variation of calorific value of briquette was not significant in depend of biomass contents.

In accordance with assessment of all characteristics the better briquettes was obtained from the peat and sawdust.

Published: November 2021

The main topic of research is the drainage basins of small rivers, which in recent years have become objects of close attention due to the high degree of their transformation associated with significant anthropogenic loads. The article presents a methodology for geoecological analysis of anthropogenic loads on the catchments of small rivers, an assessment of the degree of natural protection of the territory and a comprehensive description of the ecological state of the Yaselda river basin using GIS technologies. The paper considers the results of the study of the geoecological state of small catchments by assessing various indicators of the natural protection of the territory and factors of anthropogenic load. The scientific novelty of the research consists in the development of a methodology for assessing the geoecological situation of small catchments of the rivers of the Belarusian Polesye on the basis of a matrix of attributive indicators, which allows, taking into account generalized point estimates, to identify categories of lands with different geoecological situations. As a result of the research, a hydrographic zoning of the river basin was carried out. Yaselda, eight small private catchments (sub-basins) were identified, cartographic material was digitized, statistical data were collected, a database was created on various physical-geographical, socio-economic and ecological-hydrographic indicators. In this work, for the first time, the natural resource potential of small catchments of the Yaselda river basin is studied and presented, the natural environment-forming factors are assessed, and the main anthropogenic factors are identified, their qualitative and quantitative characteristics are carried out.

Published: November 2021

The catchment basin differentiation of the suburban territory of Minsk has been performed. The catchments of reservoirs used for the city's water supply and recreation of urban dwellers have been identified as a priority for water protection measures.

The landscape-ecological conditions of the identified basins, which determine the specificity of pollution of the rivers on which the reservoirs are built, have been evaluated. The differences in the economic development of the basins are revealed. The predominant importance of agriculture as a source of water pollution has been established. An assessment of the chemical pollution of reservoir waters with biogenic substances and their ranking according to its intensity was carried out, according to which they are combined into three groups, including reservoirs with periodic pollution (frequency of exceeding the MPC – 10–30 %), reservoirs with non-accidental pollution (30–50 %) and reservoirs with stable pollution (50 %). Comparison of the intensity of pollution of reservoirs with the forest cover of their drainage basins is carried out. It showed no relationship between them. On this basis, the need was identified for the widespread

adoption of additional measures to form the natural frameworks of the basins, including those with high forest cover.

Katılımcılar, dört hafta süresince araştırmacı tarafından hazırlanan yaşam becerileri odaklı etkinliklere katılmışlardır. Etkinlikler pandemi nedeniyle çevrim içi geçekleştirilmiştir. Veri toplama aracı olarak görüşme ve gözlem kullanılmıştır. Veriler içerik analizi kullanılarak analiz edilmiştir. Analiz sonucunda yedi tema, 14 kategori ve 76 koda ulaşılmıştır. Araştırmada, yaşam becerileri eğitimine katılan öğrencilerin, atölye çalışmalarının okuldaki etkinliklerle benzer ve farklı yönleri olduğunu düşündükleri, yaşam becerileri eğitimi hakkında olumlu görüş belirttikleri, eğitimin güçlü ve zayıf yönlerinin farkında oldukları, yaşam becerileri eğitiminin birçok becerinin geliştirilmesine katkısı olduğunu düşündükleri, etkinliklerin çevrim içi olması nedeniyle zorluklar yaşadıkları, bazı etkinlikleri daha ilgi çekici buldukları, okullarda bu eğitimin yaygınlaştırılmasını istedikleri sonuçları ortaya çıkmıştır. Ayrıca öğrencilerin yaşam becerileri eğitiminin 21. yy becerilerini geliştirmesi açısından önemli olduğunu düşündükleri görülmüştür. Yaşam becerileri eğitimine katılan öğrencilerin bu tür eğitimlerin yaygınlaştırılması gerektiği görüşü dikkate alınarak bu tür araştırmaların ve verilen eğitimlerin sayısı ve kapsamı artırılmalıdır.

Purpose: The purpose of the study was to examine the influence of tendering processes on the performance of National Government constituency development fund projects.Methodology:  The study adopted a case study design to achieve in-depth understanding of the constituency while drawing inference on similar situations in other constituencies in Kenya. The study targeted 359 projects of various types across the constituency. However, for efficiency and accessibility, a sample of 60 projects were selected using stratified random sampling where the different categories of projects form the strata from which samples were selected. The study employed three tools to collect data; questionnaire, interviews and record analysis review. These tools were appropriate due to the nature of data which ranged from opinions, structured data and reports on project implementation. Interviews were conducted with sub-county based officers to get in- depth information on the challenges faced by NG-CDF projects particularly those that relate to procurement. The study adopted descriptive statistics to analyze data which is presented by use of bar graphs, pie charts and tables.Findings: The study established that, there is indeed a relationship between tendering processes and project performance; 47% of the projects under study that were initiated during period delayed due to factors associated with tendering processes; Similarly, 49% of the projects studied experienced cost escalations during the implementation period. 60% had to be redone at certain stages of project implementation. Further the study established that the effects of faulty processes included: late deliveries; non-purchase of required items; escalation of procurement budget; delivery of small quantities; delivery of wrong material sizes; non-delivery of ordered items; overpricing among others.Unique Contribution to Theory, Practice and Policy: The study recommends the need to enhance supplier performance through; cross-functional team working of relevant county and national government departments, focused supplier development processes which includes training through continuous exposure to relevant regulatory requirements and improvement in the quality of Project Management Committee membership devoid of political inclinations.

Published: November 2021

The purpose of this paper is to provide answers to the following research questions: Is effective mentoring a function of culture, learning or hereditary, birth/ nature? Or are people born with certain traits that make them more effective or better mentors than others or is it based on learning or socialization/ nurture?; Is cross gender or cross-racial more effective than mentoring based on demographic similarities characteristics? Are there some types or techniques or practices of mentoring that are more appropriate or more suitable to some demographic groups or populations – women, blacks and other racial minorities etc. than others? This paper defines mentoring, discusses competing schools/ theories of mentorship, as well as typologies of mentoring approaches. The paper concludes that multiple/ group mentoring approach is indicative of the new trend in the business; and that while each mentoring technique or model supplements or complements the other, multiple mentoring styles or systems tend to present the best possible path to achieving efficiency and effectiveness. Finally, it recommends appropriate mentoring strategies and techniques to improve mentoring that include programs that take into account demographic similarities between mentors and protégés, gender and race-based norms, stereotypes and discrimination, as well as cultural diversity.
A produção do espaço em Portalegre/RN
Authors: Barreto Filho Boanerges de Freitas
Published: November 2021

A centralidade das cidades na sociedade capitalista é inegável. A cidade é o lócus privilegiado em que as forças capitalistas se manifestam da forma mais vigorosa através das modificações das paisagens naturais pela infraestrutura construída. À medida que a acumulação de capital se intensifica novas estruturas geográficas são forjadas e modificam incessantemente as relações socioespaciais. Este trabalho tem como objetivo analisar a produção do espaço na cidade de Portalegre/RN. Para tanto, recorreu-se à pesquisa de campo, interpretando a realidade a partir da coleta de dados primários (imagens capturadas com uso do Google Earth Pro e entrevistas com os moradores mais antigos), bem como, pesquisa documental e bibliográfica. As expansões recentes perceptíveis em Portalegre/RN decorreram da estruturação de equipamentos turísticos construídos e/ou incentivados pelo Poder Público, pela construção de bairros populares nas franjas da cidade a partir da ação estatal e pela disposição de alguns proprietários de áreas nos arredores da cidade em loteá-las.
Secret
Authors: Gagnon Eric
Published: November 2021

Tout secret institue une division entre ceux qui le détiennent et ceux qui en sont exclus. Le secret lie étroitement parole et pouvoir. Son étude est une bonne introduction à l’anthropologie du pouvoir, aux manières dont il s’exerce et aux façons de s’en soustraire. Elle est également une bonne introduction à l’anthropologie de la parole : ce que l’on dit et ce que l’on tait.
