Published: June 2024

Objective: A Compliant Joint of humanoid robot is a spring-loaded assembly, which is used to interact safely with the environment, and it helps to stabilized sudden shock and vibration in the robotic system. At the moment, compliant joints are required to optimize their size and dimensions which result into optimized weight and factor of safety of humanoid robot. Methods: Analysis is carried out using Response Surface Methodology (RSM) and Multi-Objective Genetic Algorithm (MOGA) using ANSYS. The current study employed goal-driven optimisation using ANSYS Workbench to minimise weight and achieve the required factor of safety range for the compliant joint. To find out range of variables such as rim thickness, shaft diameter, base thickness, module thickness and spoke thickness affecting on responses such as factor of safety and geometrical mass of compliant joint single factor single response parametric analysis is carried out. Findings: Based on trend of preliminary analysis variable range and combinations are selected to study interaction effect of parameters to obtain favorable factor of safety and low geometrical mass. The optimized compliant joint is compared with various design and validated through the developed actual module. Novelty: Eventually, the geometry mass of the compliant joint was reduced from 0.8604 kg to 0.6449 kg, resulting in a lighter weight (24.06% reduction) with a 1.7533 factor of safety and more compact in size (outer diameter is shrink from 142 to 126 mm).

The southwest (SW) and northeast (NE) monsoon winds significantly affect the oceanographic and climatic changes over the Bay of Bengal (BoB). We present here detailed geochemical and isotopic records from two sediment cores (SK157 14; 5°11′ N: 90°5′ E and SK157-16; 8°46′ N: 90°18′ E), collected from the southern BoB. In this study, we mainly focus on variations in paleoproductivity and terrigenous fluxes introduced into the BoB since last ~70 kyr: We have reconstructed biogenic barium (Babio), calcium carbonate (CaCO3) content, and total organic content (TOC) in both sediment cores to infer paleoproductivity during the period of study. The distributions of productivity proxies in both these cores indicate that the productivity may have been significantly high during MIS 1 and MIS 3 (warmer interglacial periods), when SW monsoon was intensified. The terrigenous proxies (Al%, Ti%, d(0.9)) show that the southern BoB may have received higher terrigenous input during the MIS 2 and MIS 4 (glacial periods) coinciding with the intensification of NE monsoon. The weathering proxy (K/Al), in contrast, shows no significant changes during MIS 2, 3 and 4. However; a significant shift is seen during glacial to Holocene transition.

Published: June 2024

Petrographical, mineralogical and geochemical studies were carried out on the beach sands of Limbe (South-West Cameroon) to highlight their provenance, source rocks alteration and the tectonic framework. The Limbe beach sediments were classified as sandy litharenite type. The sediments were derived from mafic and andesite source rocks. The sediments are composed of quartz, olivine, augite, amphibole, pyroxene, plagioclase, potassium feldspar, muscovite and biotite, indicating the primary phases of magmatic source rocks; kaolinite and illite in the secondary phase; and rutile in their residual composition. The presence of ferromagnesian minerals indicates that they were derived from the mafic rocks, which are the basalts of the Cameroon Volcanic Line (CVL). However, the presence of quartz associated with plagioclase and feldspars suggests that alkaline granites played a minor role in the sedimentation of the Limbe beaches. Total Quartz - Total Feldspar - Total Lithic Fragments (Qt-Ft-Lt) mineralogical relationships demonstrate that these beach sediments would be formed in an undissected arc tectonic context, typical of volcanic sources with high relief producing black sands or sands enriched in iron oxides. Their microscopic characteristics of angular to subangular shapes suggest that the magmatic sources are proximal to the shoreline deposits. The characteristics of microporosity, iron oxide inclusions, conchoidal fracture, heavy mineral grains, and opaque minerals support this proximal source. The conchoidal fractures defining the angularity of these beach sediments would suggest its derivation from crystalline rocks. The predominance of heavy minerals suggests that the rocks proximal to the beach have been altered. The abundance of primary minerals associated with these secondary heavy minerals justifies the existence of unweathered lithic grains in the source rocks and an alteration that occurred under a tropical monsoon climate that ranged from semi-humid to humid. The use of the multi-element tectonic discrimination diagram implies an arc framework that is compatible with the geology of the study area.

Published: June 2024

The petroleum industry is becoming more concerned about sand production because of the mounting difficulties it causes, along with the accompanying technological and operational obstacles. In this study, a field case in the south of Iraq was carried out to analyze the potential of sanding and rock collapse. This investigation has focused on the upper and lower sand layers, which are sandstone reservoirs within this field. To achieve the purpose of this study, a One-Dimensional Geomechanical Model was established along the area of interest. The critical drawdown pressure (CDDP) at which the well may be produced without experiencing shear failure or sanding was then determined at various depletion rates. The results indicated that as the rocks strength increases, so does depletion and the quantity of sand-free drawdown. Because the upper sand unit has a higher critical bottom-hole flowing pressure (Pcw), it is possible that it will begin producing sand before the lower unit. Sanding becomes more likely with each drawdown when the reservoir pressure reaches approximately 2400 psi. Finally, this research may be used as a predictor of the likelihood of sanding over the well’s productive life and as a guide for production engineers seeking to achieve optimal completion performance.
Remote Sensing-based Morphometry on the Petroliferous Cambay Rift Basin (Gujarat, Western India)
Authors: Surabhi K , Biswas Mery , Mukherjee Soumyajit
Published: June 2024

The Cambay Rift Basin (CRB) is a product of rifting in western India that formed during India’s drift following the breakup of Gondwanaland during the Early Jurassic and Tertiary Periods. Being petroliferous, the basin has attained paramount attention. Seismicity in CRB proves its present-day tectonic sensitivity. Several NNW-SSE, NW-SE and NE-SW trending faults regulate the channel morphology within a portion of the basin. Drainage network systems are proxies of active faulting. Geomorphic indices e.g., long profile analysis, basin-scale parameters, stream length gradient index and sinuosity index along the main channels in the five watersheds have been evaluated in this work. The Index of Active Tectonics (IAT) is derived from the basin-scale parameters and is clubbed into three classes: class 1 (IAT = 1.4 - 1.9), class 2 (IAT = 1.91 - 2.4) and class 3 (IAT = 2.41 - 2.9). IAT Class 1 indicates a higher present-day tectonic activity than the other watersheds such as 1, 2 and 5. Watersheds in the northern and eastern Cambay region (watersheds 3 and 4, and portions of 1 and 5) exhibit higher tectonic activity. Slope breaks and low sinuosity index near the crossing-points in these northern and eastern portions indicate active / weak zones. Along these zones, channels incise vertically and more efficiently than laterally in watersheds 3 and 4. These weak zones may indicate older structures such as lineaments and faults. The Ahmedabad-Mehsana block in watershed 3 and partly in watershed 1 within the CRB with several oil fields are tectonically highly active. Therefore, well-bore stability studies need to be carried out in this block.
Demineralization of Coal from Johilla Coalfield using Neutrophilic Native Bacteria: A Novel Technique to obtain REE from Coal
Authors: Rai Shweta , Lata Singh Asha , Singh Prakash K.
Published: June 2024

Mineral matter in coal is the host of several environmentally sensitive elements and a potential source of Rare Earth Elements (REE). During combustion, some trace elements are liberated as gas, while others get concentrated in ash, contaminating soil and local water bodies. Minimizing the inorganic content makes the coal clean and eventually increases its calorific value. Bacteria serve as an eco-friendly remediation tool, particularly neutrophilic ones that facilitate the treatment at mild pH and ambient temperatures. Use of native bacteria accelerates the treatment process by readily adapting to substrates. We present the remediation potential of three native neutrophilic bacteria in this study. After six days of treatment, Bacillus sp. CpH06 has reduced ash yield by 15.96%, trace elements by 26% to 75%, and REE by 24% to 50%. Bacillus anthracis CpH08 has reduced ash yield by 22.6%, trace elements by 6.4% to 70.5%, and REE by 8.4% to 37%. Maximum ash yield reduction of 22.91% was attained by the Cronobacter sp. CpH10 including reduction of 8.1% to 73% of trace elements and 26% to 48% of REEs. The FTIR spectra reveal alterations in both peak intensity and position of inorganic functional groups resulting from the removal of elements, formation of new bonds, and the elimination of certain pre-existing functional groups. XRD spectra indicate bio-oxidation mechanism, exhibited by the removal of copper sulfate hydroxide and pyrite along with formation of Jarosite and metal-sulfide peaks. The findings encourage further research on the effectiveness and performance of these bacteria on diverse types of coals.

Published: June 2024

Landslides often result in damage to property and loss of life in the Himalayan Region because of high seismicity and rugged terrain. To address this issue, the current study focused on developing a landslide inventory based susceptibility map for Kargil-Ladakh Region of North-Western Himalaya. The landslide susceptibility map for the region was generated with the help of Frequency Ratio (FR) Method, landslide inventory layer and eleven influencing factors such as; elevation, geomorphology, aspect, slope, plan curvature, lithology, rainfall, profile curvature, distance from road and lineaments, temperature, and land cover. The results reveal that approximately (50%) of the study-area lies under moderate to very high susceptibility zones. The low and very low susceptibility zones cover the remaining (50%) of the study-area. The findings highlight that several factors significantly contribute to landslide occurrences in the region, namely slope, road network, elevation, rainfall, and land cover. The northern part of the study area is particularly susceptible to landslides due to the presence of the national highway, a high concentration of settlements, and increased infrastructure development. Furthermore, areas surrounding local highways and community road networks show moderate landslide susceptibility. The results were validated with the help of the Receiver Operating Characteristic (ROC) curve, yielding a value of (82%) which is well within the acceptable limit. The results underscore the importance of developing site-specific landslide mitigation strategies to safeguard vulnerable communities in this strategically significant border region of India.

Published: June 2024

This study identifies and analyses megatrends of global development and how conceptual and applied aspects of this megatrends are treated in the expert-academic community by outlining the specifics of megatrends of global development in the international political sphere. Megatrends of global development such as the cyber revolution, the transition to information society based on the production and consumption of information, the growing role of network structures, on world politics, increasing consumption, hyper-consumption as a complex systemic phenomenon have a significant impact on world politics. The paper summarises the megatrends of global development that will shape the world in future. The "compression" of historical and political time as a megatrend of global development is reflected in the increase of the intensity of historical events and the decrease in the duration of historical and political cycles. There is a threefold transformation of the modern political organisation of the world: the transformation of the Westphalian world political model, which is determined by globalisation as a megatrend of global development, the transformation of the modern international system, largely due to integration as a megatrend, and the transformation of political systems. A change in the hierarchy of leading international actors, a crisis in the institution of global leadership, a rethinking of the power of leading global actors, and the emergence of new potential political and economic global leaders are projected.

Published: June 2024

In response to the gaps in understanding the causal relationship between seismic waveform features and the types of seismic events, this research is focused on seismic events of low magnitude (ML≤3.0) in the North China region. Using the Bayesian network theory, we conduct an analysis to infer event types for natural earthquakes, artificial explosions, and mining collapses, and the outcomes achieved notable efficacy for the discrimination of seismic events. Through the analysis of seismic waveforms from 1818 events, we systematically extracted and quantified 55 features in temporal, spectral, and energy domains, which were then recoded as node variables for subsequent analysis. The new data set was subject to select nodes with strong associations to the node type. Subsequently, Bayesian network topologies were constructed using three different algorithms to reconstruct the custom network, calculating posterior probabilities and marginal probabilities. Simultaneously, an extensive evaluation with precision–recall curves of the network structure was carried out, encompassing accuracy, precision, recall, and F1-score. Ultimately, sensitivity analysis was performed on each node to reveal the extent of the influence of node variations on the inference of the node type. The findings showed that the sensitivity of discrimination of seismic events was notably high for several features, including high-frequency P/S spectral ratio values (11 to ∼20 Hz), central frequency, dominant frequency, average frequency, rise and decay average frequency, the real part of the complex cepstral coefficients, peak ground acceleration, and zero crossing. In the classification of natural earthquakes, artificial explosions, and mining collapses, it was observed that the probability of mining collapses was maximized when peak ground acceleration was less than 1526.08, and concurrently, the P/S spectral ratio (11 to ∼20 Hz) fell within the range of −0.25 to −0.02.

Published: June 2024

Deciphering a comprehensive 3D fault model for the regions with moderate-to-strong earthquakes is crucial for understanding earthquake triggering mechanisms and assessing future seismic hazards. On 21 May 2021, a massive Ms 6.4 earthquake occurred in Yangbi, Dali City, China, near the northern Red River fault zone. Despite numerous studies conducted over the past two years, the seismogenic fault of this earthquake remains a topic of controversy. In this article, we refine the workflow for 3D construction of fault surfaces from Riesner et al. (2017) and used it for the Yangbi earthquake. We constructed a seismogenic fault model for the Yangbi earthquake and Caoping fault from the collected multisource data. One utilizes a combination of focal mechanisms and relocated hypocenters, whereas the other combines geological and geophysical data from the study area. Upon analyzing these two fault models and the relocated hypocenter data, we propose that the seismogenic fault in the Yangbi earthquake is an undiscovered blind fault or a secondary blind fault of the Weixi–Qiaohou fault, rather than the surface-emerging Caoping fault.

A FAMÍLIA E O AMOR: UMA LEITURA DA EXORTAÇÃO APOSTÓLICA PÓS-SINODAL AMORIS LAETITIA, DO PAPA FRANCISCO
Authors: Lemos Carolina Teles
Published: June 2024

Apresentamos, aqui, uma leitura da Exortação Apostólica Pós-Sinodal Amoris Laetitia (a alegria do amor), do Papa Francisco. O documento, que está dividido em nove capítulos e mais de 300 parágrafos, recolhe os resultados de dois Sínodos sobre a família convocados pelo Papa Francisco em 2014 e 2015. Nossa leitura apresenta a relação estabelecida pelo Papa entre o amor e a família. Em um primeiro momento, destacamos qual concepção de amor transparece na Encíclica e, em seguida, como tal amor é proposto às famílias. De nosso ponto de vista, o Papa, no decorrer da Encíclica, apresenta uma visão realista sobre as realidades das famílias, no que tange ao amor. Mas é essa mesma realidade que chama e desfia as famílias à construção de relações mais amorosas e aponta para a necessidade de que seja criada e consolidada uma pastoral familiar consciente e crítica.

A comparative study on the effect of intrathecal nalbuphine and buprenorphine as an adjuvant to 0.5% hyperbaric bupivacaine in elective infraumbilical surgeries
Authors: Arunkumar R , Nimi G  , Sandhya K
Published: June 2024

: Subarachnoid blockade provides excellent operating conditions for lower abdominal, orthopedic, pelvic, urological, gynecological and lower extremity surgery. Most subarachnoid anesthetics are single shot injections and have a definite duration; hence opioids have been used along with local anesthetics in subarachnoid block to prolong its effect, duration, quality of analgesia and minimize the necessity of postoperative analgesics.

: The primary objective of the study was to assess the onset and duration of sensory and motor blockade. The secondary objective of the study was to compare the hemodynamics, duration of postoperative analgesia and the complications encountered between the two groups.

: A prospective randomized double-blinded study was done in 120 patients divided into two group with 60 in each group as group N and group B by computer generated random numbers. Group N received 0.5% Heavy Bupivacaine (3.2ml) + 0.6mg of Nalbuphine (0.3ml) to a total volume of 3.5 ml and Group B received 0.5% Heavy Bupivacaine (3.2ml) + 90µg of Buprenorphine (0.3 ml) to a total volume of 3.5 ml for spinal anesthesia. The differences between the groups were statistically analyzed with the Independent t test for continuous variables and Pearson’s chi-square test for categorical variables. Observations and results: The onset of sensory block (p=0.303) and motor block (p=0.510) was observed to be faster in group N when compared to group B with statistical insignificance, but the duration of both sensory block (p˂0.001) and motor block (p˂0.001) was more pronounced in group B when compared to group N with statistical significance. The duration of effective analgesia was more pronounced in group B (468.35±30.57 minutes) compared to group N (362.70±35.53 minutes).

: The duration of the sensory and motor block with effective postoperative analgesia were more pronounced in buprenorphine compared to nalbuphine and hence intrathecal buprenorphine is a better alternative adjuvant to intrathecal nalbuphine in elective infraumbilical surgeries.
Enhanced recovery after surgery (ERAS): A budding concept in neonatal intestinal surgery
Authors: Erram Harika , Varshney Preeti Goyal , Gupta Anshu
Published: June 2024

Enhanced recovery after surgery (ERAS) is a multidisciplinary approach, widely used in adults and children for improving patient care with reduced length of hospital stay and medical costs. However, it is poorly established and perceived as unimplementable in neonates. Recently, ERAS guidelines consisting of 17 recommendations for perioperative care in neonatal intestinal surgery are laid down by the ERAS society. To elicit the feasibility of implementing ERAS protocol, we did an observational pilot study in neonates undergoing intestinal surgery at a tertiary centre to know the number of recommendations from ERAS guidelines already being followed routinely.

Data was collected for the neonates undergoing intestinal surgery for three months. All the relevant details were noted and analysed to find out the number of recommendations from ERAS guidelines already being implemented and the postoperative outcome of these neonates.

Twelve neonates underwent intestinal surgery for obstruction and atresia during the study period. Eight out of 17 ERAS guidelines were already followed as a routine protocol in all these patients. Nine patients were extubated on table, one patient was extubated within 24 hours of surgery and two patients succumbed to death. Ten neonates were discharged from hospital within 6-8 days of surgery.

Many recommendations from ERAS guidelines for neonatal intestinal surgery are already being followed routinely, suggesting that the implementation of complete ERAS protocol is easily possible, which may further improve the perioperative outcome with reduced length of hospital stay.

Intra canalmedicament must be completely removed from the pulp space for better penetration of sealers. Various methods of irrigant delivery are used for removal of medicament from root canals. Removal of N-acetyl cysteine when used as an intracanal medicament hasn't been studied yet.

To compare efficacy of different irrigation techniques, ultrasonic, sonic, navi tips, side vented needles in removal of N-acetyl cysteine as an intracanal medicament- an study

Fifty-two maxillary anterior teeth were decoronated and standardized to a root length of 13 mm. Root canals were prepared with Protaper Universal rotary system. N-acetyl cysteine paste was placed in root canals with lentulospiral and kept in an incubator for 7 days. Then four groups (n=13) were established according to the removal technique- Group 1- Passive ultrasonic irrigation, Group 2- Sonic irrigation, Group 3- Manual irrigation with NaviTip, Group 4- Manual irrigation with side vented needles. Each tip was placed 2 mm short of working length and irrigation was done using 5.25% sodium hypochlorite. Final irrigation was done, then roots were split buccolingually and evaluated for residual medicament under stereomicroscope at 24x magnification.

Done using Kruskal-Wallis and Mann-Whitney tests (P ≤ 0.05).

In coronal and middle third, there was significant difference in removal of medicament by Group 1- Passive ultrasonic irrigation compared to other techniques, whereas, in apical third Group 2- Sonic irrigation showed better result. Group 3-Manual irrigation with NaviTip and Group 4- Manual irrigation with side- vented needles was significantly less effective than other techniques.

Use of irrigants with activation devices like ultrasonic and sonic revealed improved removal of N- acetyl cysteine intracanal medicament.
Non-surgical management of simultaneous occurrence of internal root resorption and calcific metamorphosis: A case report
Authors: Raju Gracemol , Baranwal H.C
Published: June 2024

Internal resorption and calcific metamorphosis are two sequelae of pulpal necrosis after traumatic injuries like concussion and luxation injuries. After traumatic injury, the pulp may become completely necrosed followed by calcification of the entire root canal by the activity of odontoblastic cells. In some other cases, partial necrosis of the pulp tissue with overstimulation of odontoclastic cells and resorption of the root canal dentinal walls may happened. Commonly any of the cells become active and one of the sequelae may will continue. Rarely these two conditions will happen together. In this particular case report with simultaneous occurrence of these two conditions with symptomatic periapical abscess.

Authors: De Sousa Neto João Tomé , Guimarães Daniel Barboza
Published: June 2024

Esta análise da narrativa seriada aborda as diretrizes estabelecidas por Frederick W Taylor na sua Organização Racional do Trabalho de uma maneira crítica utilizando-se como base de comparação o funcionamento da sociedade Gem do desenho animado Steven Universo, da Cartoon Network, de maneira a estabelecer as conexões necessárias para entender as semelhanças e refletir sobre a natureza da ORT como guia de produtividade das organizações. O processo de construção dessa análise baseou-se na abordagem qualitativa e em pesquisa bibliográfica sobre a obra de Frederick W Taylor somado à coleta de dados através de observação, tendo como resultado a contribuição bibliográfica de um conteúdo que conseguiu demonstrar a possibilidade de associações entre produções recentes voltadas para o público infanto-juvenil com temas mais íntimos da teoria da administração, mesmo que essas obras não possuam um caráter fundamentalmente crítico.
Interdependência e conexões entre rotinas organizacionais: revisão e análise sobre a relação com artefatos
Authors: Figueira Erick Cardoso da Silva , Scofield Laura Vieira , Da Rocha-Pinto Sandra Regina
Published: June 2024

Pautados pela perspectiva da prática, os interesses de investigação de teóricos organizacionais vêm elevando o nível de análise, a partir do que acontece dentro de rotinas, para questões acerca da interdependência entre rotinas. Ao mesmo tempo, a evolução do papel de artefatos físicos e digitais na dinâmica de rotinas vem apresentando distintas direções, ora posicionando esses elementos como periféricos, ora como centrais. Diante disso, o objetivo deste estudo residiu em evidenciar o que a literatura produziu sobre interdependência e conexões entre rotinas organizacionais, bem como sua relação com artefatos. Para tanto, realizou-se uma revisão da literatura a partir das bases Web of Science e SCOPUS. Os seguintes aspectos foram identificados: (a) o predomínio da perspectiva da prática como lente teórica; (b) a categorização da interdependência entre rotinas; e (c) os elementos apontados como mecanismos de conexão entre rotinas. A literatura sugere que os artefatos podem conectar rotinas organizacionais ao transferir informação e conhecimento; ou como bases de entendimento para a execução de ações. Assim, este estudo propõe uma agenda de pesquisas para orientar a conceitualização de conexões entre rotinas organizacionais, considerando o papel dos artefatos nessa dinâmica.

Authors: De Azevedo Cardoso Lucas Tomás , Castilho Adriana Guedes de
Published: June 2024

A presente pesquisa tem como objetivo refletir sobre as dificuldades que ocorrem para efetivar a inclusão das pessoas com autismo no mercado de trabalho. Essa pesquisa se faz relevante, pois busca contribuir para o desenvolvimento de estratégias e políticas que promovam a inclusão efetiva desses indivíduos, valorizando suas habilidades e potenciais no ambiente de trabalho. Para alcançar esse propósito, foram coletados dados por meio de questionários enviados aos gestores de Recursos Humanos, a fim de compreender o atual processo de inclusão e os obstáculos enfrentados nesse contexto. Além disso, a revisão bibliográfica desempenhou um papel fundamental nesse estudo, permitindo identificar a obrigatoriedade estabelecida pela Lei nº 8.213, de 24 de julho de 1991, conhecida como lei de cotas, que norteia a inclusão de pessoas com deficiência em geral, estabelecendo a reserva de vagas para esses indivíduos no mercado de trabalho. Os resultados revelaram a existência de estereótipos na contratação de pessoas com autismo, bem como uma tendência de não contratação daqueles com deficiência intelectual.

Este trabalho tem como objetivo analisar o uso da rede social Instagram da empresa Limpe Fácil Paris, localizadas na cidade de Guarabira, que atua com a comercialização de produtos de limpeza, como ferramenta de impulsionamento de negócio. O foco do trabalho foi fazer o posicionamento da marca por meio do aprimoramento do perfil do Instagram, de modo a atrair seguidores como potenciais clientes e impulsionar as vendas. A pesquisa é do tipo descritiva e foram analisados dados quantitativos coletados a partir do próprio mecanismo de mensuração da plataforma, o Instagram, envolvendo: alcance, engajamento, seguidores, perfil do cliente em relação a sexo, faixa etária e localização. Estes dados foram coletados a partir da prestação de serviço ofertada a empresa Limpe Fácil Paris, pela Empresa Júnior do Instituto Federal da Paraíba (IFPB), do campus Guarabira, a Singular Empresa Júnior. A partir dos resultados obtidos, pode-se perceber que a ferramenta Instagram, de fato atua como uma impulsionadora para o desenvolvimento dos negócios, sobretudo quando bem planejada. No caso desta pesquisa, isso pode ser percebido, principalmente, pelo aumento de contas alcançadas e pelas ações de engajamento, que estão relacionados a interações, como comentários e compartilhamentos.  Percebe-se que o aumento de seguidores não foi significativo neste período de atuação junto à empresa, o que nos mostra que para atuar nas mídias digitais a empresa deve concentrar esforços diários e ter uma postura ambiciosa diante das possibilidades de alcance que o meio digital proporciona.
Exploring economic activity from outer space: A Python notebook for processing and analyzing satellite nighttime lights
Authors: Patnaik Ayush , Mendez Carlos
Published: June 2024

Nighttime lights (NTL) data are widely recognized as a useful proxy for monitoring national, subnational, and supranational economic activity. These data offer advantages over traditional economic indicators such as GDP, including greater spatial granularity, timeliness, lower cost, and comparability between regions regardless of statistical capacity or political interference. However, despite these benefits, the use of NTL data in regional science has been limited. This is in part due to the lack of accessible methods for processing and analyzing satellite images. To address this issue, this paper presents a user-friendly geocomputational notebook that illustrates how to process and analyze satellite NTL images. First, the notebook introduces a cloud-based Python environment for visualizing, analyzing, and transforming raster satellite images into tabular data. Next, it presents interactive tools to explore the space-time patterns of the tabulated data. Finally, it describes methods for evaluating the usefulness of NTL data in terms of their cross-sectional predictions, time-series predictions, and regional inequality dynamics.

Equilibrium in Practice
Authors: Trivedi Nripesh
Published: June 2024

In [1], it is proposed that n players are in equilibrium if all of their strategies yield highest possible expectation for the respective players. This equilibrium is related to the equilibrium proposed in this paper. In this paper, I propose an equilibrium where a group of n players are involved. Equilibrium of the group is equilibrium of the individual players since every player lives in group. Inspired from this conclusion, I propose that equilibrium of the individual players is the equilibrium of the group. To explain in plain and simpler words, equilibrium of the group is the equilibrium of the individual players since each player lives in the group.

La influencia del rebranding visual en la percepción de marca Caso: Spot Publicitario “Swarovski Wonderlab”
Authors:   , Coz Rosas Maria Lucia
Published: June 2024

Hoy en día, las marcas saben que para ser recordadas por su público es esencial lograr conectar con ellos y adaptarse a los cambios del mercado y al nuevo perfil del consumidor. Por ello, las marcas buscan estar actualizadas y muchas lo demuestran con una renovación de su imagen a través del rebranding visual, y con una transformación de su narrativa publicitaria mediante el storytelling. La publicidad desempeña un papel sumamente importante en la proyección de la nueva imagen de marca, ya que de esta depende una respuesta positiva por parte del público objetivo. Dentro de un mercado reducido como el de joyerías de alta gama, es muy importante que las marcas se mantengan vigentes y se diferencien de su competencia de forma innovadora a través de sus campañas publicitarias. La presente investigación concluyó que el rebranding visual y las herramientas publicitarias influyen en la percepción de la marca por parte de los grupos objetivo. En ese sentido, la metodología se centró en un estudio cualitativo con un paradigma fenomenológico no probabilístico, en el que se utilizó una guía de preguntas para observar la influencia del rebranding en la percepción de las consumidoras peruanas, analizando el caso de Swarovski a través del anuncio publicitario “Wonderlab”.
