RANGE-BASED NETWORK FORMATION TO SUPPORT GEOREFERENCING OF MAPPING SWARM PLATFORMS
Authors: Ladai A. , Toth C.
Published: July 2022

Abstract. Mapping platforms jointly operating in a formation are increasingly used to improve the efficiency of geospatial data acquisition recently. For example, UAS swarm mapping is gaining market share or robot platform are used for indoor mapping. These platforms are typically equipped with imaging and navigation sensors as well as have various communication capabilities. Until now, the platforms are individually navigated and georeferenced. Since the platforms are typically sharing a small area, and thus, they are within their sensing range; for example, they can see and thus track each other in optical or lidar imagery. Furthermore, new communication technologies have started to provide ranging information between communication points. Using the ranges between platforms makes it feasible to create a local geodetic network defined by the platforms. The geometric strength of the network then can be exploited to support platform georeferencing. In this study, the network formation based on ranges is investigated. Initial experiences are reported on the impact of the size of the network, the spatial distribution of the network nodes and the number of available ranges.

Abstract. Global climate change has affected the rate of rising sea level, the frequency, intensity, timing, and distribution of hurricanes and tropical storms which threatens coastal ecosystems such as Bayou Perot, Little Lake in New Orleans along the Gulf of Mexico. The impact of hurricanes could include wetland and coastal land loss. This paper compared the land cover changes around Bayou-Perot- Little Lake, New Orleans, USA following Hurricanes Ida (August 26, 2021 to August 28, 2021). Two high-resolution Sentinel 2 imagery dated before and after Hurricane Ida was compared to assess the impacts of the hurricane on the land cover around Bayou Perot. A Random Forest classification (RF) algorithm in Google Earth Engine was used to produce maps and identify areas that have experienced conversions in land use or land cover change after the hurricane. This method of classification has the advantages of high classification accuracy and the ability to measure variable importance in land-cover mapping. In addition to random classification algorithm, other analysis such as the Normalized Difference Vegetation Index (NDVI) was be used to gain a better perspective of the overall changes in vegetation across the landscape. Five main classes were considered after the classification which included water, vegetation, bare soil, built up and marsh area. The results of the land cover change showed exposed old coastal marsh, valuable dune habitat providing storm protection to estuaries, wetlands, and the coastal population destroyed.

Authors: Awad B. , Erer I.
Published: July 2022

Abstract. The process of identifying change in remote sensing images has been a focal point of research for decades now. Many classical algorithms exist, and many new modern ones are still being developed. These algorithms can be divided into supervised and unsupervised. In this work an unsupervised method is presented. This method relies on the scene alignment algorithm SIFT flow. It is shown that building upon simple principles an accurate change map can be obtained from the SIFT descriptor flow of the two input images. Furthermore, it is shown that this method despite its simplicity exceeds other unsupervised methods and comes close to supervised ones, even exceeding them in some metrics. Lastly, the advantages of SIFT flow in comparison to the supervised methods are highlighted alongside its own downsides.
FEATURE MATCHING ENHANCEMENT USING THE GRAPH NEURAL NETWORK (GNN-RANSAC)
Authors: Elashry A. , Toth C.
Published: July 2022

Abstract. Improving the performance of feature matching plays a key role in computers vision and photogrammetry applications, such as fast image recognition, Structure from Motion (SFM), aerial triangulation, Visual Simultaneous Localization and Mapping (VSLAM), etc., where the RANSAC algorithm is frequently used for outlier detection; note that RANSAC is the most widely used robust approach in photogrammetry and computer vision for outlier detection. It is known that the outlier ratio used in RANSAC primarily determines the number of trial runs needed, which eventually, determines the computation time. Over time, different methods have been proposed to reject the false-positive correspondences and improve RANSAC, such as GR_RANSAC, SuperGlue, and LPRANSAC. The specific objective of this study is to propose a filtering algorithm based on Graph Neural Networks (GNN), as a pre-processing step before RANSAC, which can result in improvements for rejecting the outliers. The research is based on the idea that descriptors of corresponding points, as well as their spatial relationship, should be similar in image sequences. In graph representation, built by the adjacency matrix of data (nodes features), there should be similarity for corresponding points that are close to each other in the image domain. From the many GNNs techniques, Graph Attention Networks (GATs) were selected for this study as they assign different importance to each neighbour’s contribution as anisotropic operations, so the features of neighbour nodes are not considered in the same way, unlike other GNNs techniques. In our approach, we build a graph in each image, because the similarity of the two-dimensional spatial relationships between points in the image domain of consecutive images should be similar. Then during processing, points with any significantly different neighbours are considered as outliers. Next, the points can be updated in the GNN layer. GNN-RANSAC is tested experimentally on real image pairs. Clearly, the proposed pre-filtering increases the inlier ratio and results in faster convergence compared to ordinary RANSAC, making it attractive for real-time applications. Furthermore, there is no need to learn the features.

Published: July 2022

Abstract. Deep Learning algorithms are increasingly used for mapping waterbodies in remotely sensed images. DeepLabV3+ is an image segmentation method that includes ASPP and encoder-decoder to retrieve pyramid spatial features at different scales and structural information respectively. Previous studies have shown that DeepLabV3+ can accurately map waterbodies in false colour infrared images. However, ability of DeepLabV3+ for extracting waterbodies in RGB images is unknown. This study tested DeepLabv3+ algorithm to extract waterbodies in the RGB bands. Sentinel 2A/B images (n = 2841) and their corresponding annotations were downloaded from Kaggle (host of public datasets) and subset images (n = 10405) of 100 × 100 pixels were cropped. From these subset images, 8941 were used for training and validation and 1464 were used for testing the trained model. Dice and Jaccard/Intersection over Union (IoU) were used for evaluating the output generated by the model. The network was trained for 50 epochs with 32 iterations in each epoch. The model trained at the end of 30th epoch was selected as final based on minimum information loss (0.0743). The average Dice and Jaccard/IoU scores for the output images were 0.8412 and 0.7169 respectively. The high scores obtained in this study indicate that DeepLabV3+ can be used for identifying waterbodies in RGB or true-colour images.

Published: July 2022

Abstract. Recent Arctic warming has fuelled interest in the weather and climate of the polar regions and how this interacts with lower latitudes. Several interesting theories of polar-midlatitude linkages involves Rossby wave propagation as a key process even though the meridional gradient in planetary vorticity, crucial for these waves, is weak at high latitudes. Here we review some basic theory and suggest that Rossby waves can indeed explain some features of polar variability, especially when relative vorticity gradients are present. We suggest that large-scale polar flow can be conceptualised as a mix of geostrophic turbulence and Rossby wave propagation, as in the mid-latitudes, but with the balance tipped further in favour of turbulent flow. Hence, isolated vortices often dominate but some wavelike features remain. As an example, quasi-stationary or weakly westward-propagating subpolar anomalies emerge from statistical analysis of observed data, and these are consistent with some role for wave propagation. The noted persistence of polar cyclones and anticyclones is attributed in part to the weakened effects of wave dispersion, the mechanism responsible for the decay of mid-latitude anomalies in downstream development. We also suggest that the vortex-dominated nature of polar dynamics encourages the emergence of annular mode structures in principal component analyses of extratropical circulation. Finally, we consider how Rossby waves may be triggered from high latitudes. The linear mechanisms known to balance localised heating at lower latitudes are shown to be less efficient in the polar regions. Instead, we suggest the direct response to sea ice loss often manifests as a heat low, with radiative cooling balancing the heating. If the relative vorticity gradient is favourable this does have the potential to trigger a Rossby wave response, although this will often be weak compared to waves forced from lower latitudes.

Raíces escolásticas de la teoría de la propiedad de John Locke
Authors: Cendejas Bueno José Luis
Published: July 2022

En este trabajo se aborda la larga trayectoria que va del pensamiento jurídico romano hasta la explicación que da Locke del origen de la propiedad, del dinero y, en última instancia, del poder político (civil government). Tanto Vitoria y Suárez como Locke parten de considerar un estado prepolítico primigenio (de inocencia en Vitoria y Suárez, de naturaleza en Locke) de igual libertad para todos (omnium una libertas) y propiedad común (communis omnium possessio), en el que se habría encontrado la humanidad antes del establecimiento de las instituciones características del estado civil. A pesar de la presencia de elementos de continuidad con respecto a Vitoria y a Suárez, mediante la sustitución del estado de inocencia prelapsario por un status naturae que no precisa de lectura teológica alguna, y que Locke sitúa en un tiempo histórico realmente existente, el autor inglés formula una teoría estrictamente secular, basada en la larga tradición del ius naturale, sobre los orígenes del gobierno civil y de la propiedad privada.
El poder del soberano para manipular el dinero: Juan de Mariana y John Locke

La presente investigación analiza la respuesta teórica que recibió uno de los factores causantes de la denominada Revolución de los precios en Europa durante los siglos XVI y XVII, concretamente el aspecto relacionado con las alteraciones de los valores monetarios de las piezas de vellón y plata en Castilla e Inglaterra. En ambos países estos episodios fueron analizados con rigor desde el punto de vista teórico tal y como se desprende del estudio de las ideas monetarias del periodo que se desarrollaron en los dos territorios. En este estudio, a la luz de los acontecimientos históricos que tuvieron lugar, analizamos los fundamentos del pensamiento monetario de Juan de Mariana y de John Locke quienes se oponen a que el soberano altere los valores monetarios con intereses fiscales, así como la diferente acogida que tuvieron.

Antitrust Reform and the Nirvana Fallacy: The Case Against a New Sherman Act
Authors: Joshua D. Wright  , Jennifer Cascone Fauver
Published: July 2022

Demands for major antitrust reform are coming from all directions: politicians, industrial organization (IO) economists, and antitrust lawyers. While the political, legal, and economic debates vary in important ways, they all boil down to a single question: Do we need a “New” Sherman Act? Progressive IO economists argue that a “crisis” of competition in markets—evidenced by increasing levels of aggregate industry concentration—has resulted in systematic market power across the economy, and that a crisis of institutional credibility in the courts has biased antitrust law in favor of defendants. However, as this Article illustrates, the economic and empirical evidence support neither proffer. Rather than reform based on upon evidence of market failure or a failure of antitrust institutions, Progressive IO economists call for reform based upon the nirvana fallacy—a comparison of the today’s institutions with an imaginary set of perfect institutions guided by omniscient and well-intending economists. But economics is not on the agenda of current proposals for antitrust reform and calls for a “New” Sherman Act threaten to upend the long-standing partnership between law and economics on which the consumer welfare standard is predicated. Without such a partnership, antitrust institutions will struggle to achieve their objective of promoting competition on behalf of Americans.
Evaluation of GeneXpert MTB/RIF Assay for Rapid Diagnosis of Tuberculosis and Detection of Rifampicin Resistance in Extra Pulmonary Specimens
Authors: Singla Sonam , Sarma Smita , Sengupta Sharmila
Published: July 2022

Introduction: Extra pulmonary tuberculosis (EPTB) accounts for 15%-20% of all tuberculosis (TB) cases. Diagnosis of EPTB is difficult due to its pauci-bacillary nature. The slow growth rate of mycobacterium makes isolation and identification by culture delayed. The Xpert MTB/RIF assay detects both TB and resistance to rifampicin in less than two hours. Hence we compare Gene Xpert with TB culture to diagnose EPTB and determine rifampicin resistance.
Methods: The study was conducted between Nov 2016 to Oct 2017 and all EPTB specimens were collected.The collected specimens were processed for acid fast stain, MTB/RIF assay and liquid culture by MGIT (Mycobacterial Growth Indicator Tube).
Results: A total of 340 EPTB specimens were evaluated. Culture positivity rate was 22.4%. Gene Xpert was positive in 21.7% cases. The sensitivity of Xpert was 68% and specificity was 92% with culture as gold standard. The sensitivity of Gene Xpert in various samples ranged from 93% to 12% being highest in pus sample (93%) and lowest in pleural fluid (13%) whereas the specificity reversed being 100% in pleural fluid and 79% in pus. MTB detected 22 more cases than culture hence Xpert identified 29.7% more cases than culture. We also observed that Xpert missed 9% culture positive cases.
The culture confirmed rifampicin resistant was observed in 12 cases while Gene Xpert identified in 8 among them however in 3 cases Xpert was rifampicin sensitive.
Conclusion: Our study confirms that Xpert MTB/ RIF assay is an important advancement in diagnosing EPTB. Although it cannot replace the conventional techniques but can contribute significantly in an early diagnosis and management of EPTB . Hence a combined approach including acid fast stain, culture identification and sensitivity and Gene Xpert as well as appropriate sample should be sent for an early and reliable diagnosis of EPTB.

Key words: Extra pulmonary tuberculosis, Mycobacterium tuberculosis, Gene Xpert MTB/RIF assay, rifampicin resistance, MGIT (mycobacterial growth indicator tube).

Published: July 2022

Abstract. The problem of improving the substitute players preparation system in the game of football was and remains quite current at the contemporary stage. One of the acute problems in this regard is the selection of young footballers on certain criteria. According to the analysis of the literature, it was highlighted that most specialists focus on the traditional selection criteria of young footballers and very few of them take into account the structure and content of the activity on each game. It was this criterion that was the basis of the research undertaken, where all the game actions performed by footballers on the main game positions were analyzed, in order to be able to select both the right people for these positions and their specific training, of each game position. This will ultimately lead to an increase in the quality of training of footballers, both on the playing field and for the team as a whole.

Abstract. The program regulating the content of physical education lessons, aimed primarily at the formation of motor skills, is not able to have a significant impact on improving the motor conditions of elementary school pupils. The content of the lessons has a minimal impact on the development of endurance. The purpose of the study: optimization of physical education methods of primary school. Material and methods The study was conducted on the basis of GUO Secondary School No. 31 named after V. Khoruzhey, Vitebsk, for 12 weeks. The experiment involved schoolchildren 7-9 years old (n = 48). Experimental factor - motor tasks of cyclic and complex coordination nature, heart rate 50 - 70% of the maximum, 8-10 min. Methods: generalization and analysis of literary data; control tests; pedagogical experiment; anthropometry; methods of mathematical statistics. The results of the study and their discussion. The expected, statistically reliable, training effect from the implementation of the development was not achieved. With such a value of V with 17-93% in the indicators of half of the tests, it is impossible to achieve the required reliability of differences. Therefore, it is more legitimate to evaluate the quality of the program by the growth rate of X test indicators. 700 min. for 12 weeks is not enough for changes in motor conditions to be statistically confirmed. Due to the fact that the curriculum is aimed at the formation of motor skills, there is no reason to evaluate its quality by tests reflecting the measure of the development of motor qualities. The development of motor conditions without the use of influences in the developmental mode is very difficult in the conditions of a school lesson. Conclusion. The motor tasks installed in the program allowed the subjects of the experimental group to increase their motor conditions to the level of the requirements of the age norm. The fragmentary use of influences stimulating the development of various forms of motor manifestations of endurance not only significantly improved the functionality of the cardiovascular system (P 0.02), but also contributed to their effective implementation with power and aerobic modes of motor manifestation. It should be noted that the made changes contributed to the harmonious development of all motor abilities without exception.

Introduction: People living with the human immunodeficiency virus (HIV) are generally overweight or have an altered body composition as compared to healthy individuals, showing a change in nutritional profile over time. Objective: The aim of the study was to characterize the nutritional status, estimate the prevalence of lipodystrophy, and examine the association between lipohypertrophy and lipid profile alterations, and other clinical data of HIV-infected individuals. Methods: This was a cross-sectional study on male and female subjects living with HIV, treated at a specialized outpatient clinic, aged 18 years old and over, whether using the antiretroviral therapy or not. Results: The sample consisted of 420 people with a mean age of 43.8 years (standard deviation 11.7). The length of time of the HIV infection averaged 74.6 months, and 91% of the respondents were on antiretroviral therapy. Lipodystrophy prevalence was 35.7%. Of these, 82 (54.7%) presented lipohypertrophy, 61 (40.7%) had lipoatrophy and 7 (4.6%) had a mixed syndrome. Female gender, body mass index, fat percentage, waist circumference and waist-hip ratio were positively associated with the presence of lipohypertrophy (p<0.001). High mean total cholesterol (p=0.015) and LDL fraction (p=0.028) also showed a statistically significant association with lipohypertrophy. The sampled participants had a nutritional profile compatible with overweight or obesity. No association was found between lipohypertrophy and ART and the therapy duration. Conclusion: Considering the consequences of overweight as a cause of various pathological conditions, preventive measures and interventions are highly recommended for this population.

Published: July 2022

Background: Systemic chemotherapy is the standard of care for patients with metastatic breast cancer, with an undecided role in surgery. Limited data is available for the role of surgery on the overall survival of stage 4 breast cancer in regards to luminal subtypes of patients. This is a retrospective data analysis comparing overall survival benefit and disease-free survival in stage IV breast cancer after systemic treatment and systemic disease control concerning luminal classification in the last five years. Method: Patients who had surgery and no surgery after systemic treatment and disease control were compared for 5 years overall survival as the primary endpoint and disease-free survival as the secondary endpoint. The survival benefit was also compared in regards to tumor biology (ER/PR, HER2 status) Results: Data included 430 patients, 244 in surgery and 186 in no surgery group. At one year survival for surgery performed and not performed was not significant. Five-year overall survival for surgery performed and not performed was 84.4% and 74.6%. A statistically highly significant difference in survival rates was observed (p<0.0001). The mortality rate was 15.6% in surgery performed and 25.4% in the no-surgery group which showed a significant difference among the two study groups (p=0.011). We found statistically significant differences in luminal B (p=0.01) and triple-negative breast cancer patients (p=0.001) for survival rates in surgery performed and not performed groups. Conclusion: Surgery has a positive impact on overall survival in Stage 4 patients with systemic disease control even in high-risk luminal B, Her 2 Positive, and triple-negative breast cancer patients. There was no significant difference observed in disease-free survival who were operated on or not. However, there was no local recurrence in the operated group.

Monkeypox is no longer "an uncommon viral zoonotic disease" because it has spread all over the world and the outbreak is still occurring. It is concerning that the disease has spread to other regions and countries. There is a lack of information regarding the ecological, zoonotic, epidemiologic, clinical, and public health aspects of monkeypox. Significant adverse effects are associated with the first-generation live attenuated vaccinia virus vaccinations that are stored for use in emergency situations in multiple countries. As a result of the cessation of smallpox vaccinations, an ecological void has been created in which more people have diminished or no protection against MPXV. This will increase the rate of virus transmission from animals to humans as well as from humans to other humans. Urgent research and monitoring should be carried out as part of a global initiative titled "One-Human-Animal Environmental Health."

Published: July 2022

Background: Prevalence of overweight, obesity among children age in Egypt and severe obesity among of all age groups varies very high, children's obesity is an alarming issue. Continually rising prevalence of obesity and overweight in children is a major public health concern. This is due to its various and serious health hazards on one side and its preventable nature on the other side. The problem primarily relies on the ability of parents to recognize their child's overweight/obesity, and to be aware that obesity is a risk factor for long-term health issues. Several studies showed that many parents are not concerned about their children's body weight, because they either think too little of their child's body weight or believe that obesity is inherited, thus modifiable. Parent's perception of child feeding is one of the influencing causes that contribute to child weight status. Although the prevalence of childhood obesity has increased significantly in Egypt, parents are unable to appreciate obesity in their child. Parental beliefs and practices in children’s nutrition may determine deviations in the acquisition of the child’s food preferences and in their self-regulation, who can influence their nutritional status. Childhood obesity and metabolic complications related thereto emerge as a challenge to global health in the 21st century, given its dramatic increase in the last decade in most countries Aim of the study: to assess of parental beliefs and practices about child feeding and its impact on child weight. Setting: The research was conducted on sample of parents (mother, father, children), living in some regions at Menoufia Governorate, Egypt.

Introduction: Women have a higher life expectancy than men. However, this does not guarantees a healthy life as women are often disadvantaged section of society. Additionally, women develop a series of natural physiological changes during midlife accompanied with chronic conditions including genitourinary conditions. We aimed to estimate the prevalence and determine the correlates of chronic renal failure, incontinence and kidney stones among women aged ≥45 years in India. Methods: We employed data from the first wave of Longitudinal Ageing Study in India (LASI) wave-1, 2017-2018. A sample of 32,097 women aged ≥45 years were included. Descriptive statistics were used to report prevalence along with 95% confidence interval as a measure of uncertainty. Separate multivariable regression analysis was conducted to assess the association between various socio-demographic and behavioral correlates with the outcome i.e. chronic renal failure, incontinence and kidney stones. Results: The overall prevalence of chronic renal failure was 0.53% (95% CI: 0.45-0.62), incontinence was 2.9% (95% CI: 2.72-3.09) and 2.28% (95% CI: 2.11-2.45). The multivariable regression analysis showed participants aged ≥75 years had a higher odds [AOR: 1.81 (95% CI: 1.34-2.44)] of having incontinence. Kidney stone were significantly akin [AOR: 1.98 (95% CI: 1.53-2.55)] among participants having obesity.

Introduction: Stress is defined as physical and psychological state that occurs when the individual is unable to cope with demands and pressure of situation. In the present Covid-19 era when doctors are overloaded, the stress to balance between his family and work life has increased. The modern medical workplace is a complex environment and doctors take it either exciting or depressing. The stress due to working conditions lead to many symptoms like depression, anxiety, anger, headache, insomnia. Aim of the study was to estimate the level of stress among doctors, to identify the risk factors and relieving factors for the stress and to assess the consequences of stress. Material & Methods: It is an Observational Cross Sectional Study. After obtaining permission from Institutional Ethical Committee the study was conducted on 400 doctors pursuing post graduation after MBBS and post graduate doctors. Doctors in the study work in different departments of private and government hospitals as well as private practitioners. They were included in the study only after obtaining an informed consent. All the doctors fitting into the inclusion criteria were taken into the study.

The paper aims to compare the CO2, CO, CH, and O2 concentrations in the exhaust gases of Cummins KTA 50 diesel engines of BelAZ 75131 mining dump trucks equipped with an onboard cryogenic fuel system and running on diesel and gas-diesel fuel at coal mines of Kuzbass (Russia). The research novelty lies in determining ecological efficiency when using liquefied natural gas (methane) as a motor fuel for heavy-duty mining dump trucks. In the near future, the use of this type of motor fuel will minimize the anthropogenic impact on the environment by reducing harmful emissions and provoking the environmental safety of the region where a large amount of mining equipment is used in coal mining enterprises. The demand for mining dump trucks, their operating conditions, and the world experience in converting mining equipment to liquefied natural gas (methane) were briefly analyzed. The use of alternative fuel sources for heavy-duty mining trucks is a promising way to reduce harmful emissions into the atmosphere. This paper presents a research technique. The data on the study of the CO2, CO, and CH groups and O2 concentrations in the exhaust gases of Cummins KTA 50 diesel engines of BelAZ 75131 mining dump trucks hauling rock mass are presented. The obtained data on the CO2, CO, and CH groups and O2 concentrations during diesel and gas-diesel operation of empty and laden BelAZ 75131 mining dump trucks when going uphill and downhill were substantiated. The results of calculating the average weighted emissions of the CO2, CO, and CH groups in the exhaust gases of Cummins KTA 50 diesel engines were presented.

The paper describes the design of an electroosmotic device for treating dehydration of water-mineral-organic wastewater sludge from paper production and a methodology for conducting experimental studies. As for regression equations for the reduction factor of the waste mass, specific indicators were presented: drainage fluid consumption, current strength, power consumption, and energy, depending on the voltage on the electrodes and the duration of treatment. Besides, the required waste treatment function depends on the voltage and the required waste concentration. Equations and graphs were presented. In terms of the intensity of fluid excretion, it was found that the most effective treatment is performed during the first 0.5–0.7 h. At a voltage of about 25 V, the processing time of waste (until the mass of waste is reduced to 1/3) is about 0.75 h, and at a voltage of less than 10 V, it is about 3–5 h. With a decrease in the voltage, the liquid withdrawal slows down faster. By the magnitude of the current, the separation process lasts for the first 0.7–1.0 h. By the nature of the change in the current, the process is homogeneous (differing only in intensity) at a voltage of more than 8 V. At a lower voltage, the intensity of waste separation by current strength and an increase in the duration of processing decreases sharply. The power consumption is actively growing in the first 1–2 h of processing, gradually slowing down. Then we found the proportionality of power to the applied voltage. The increase in power was associated with a decrease in the distance between the electrodes. With a decrease in the mass of waste less than 50% of the initial value, energy is less efficiently used for separating waste, and the observed increase in energy consumption during further processing sharply increases energy consumption. To reduce the final mass of waste and obtain their concentrate, it was necessary to increase energy consumption. Waste processing should be stopped when 1/3 of the initial waste mass remains due to the actual cessation of the separation of waste fractions with an active increase in energy consumption.

There are many overlaps between sustainability concepts so they are sometimes used interchangeably. This study was aimed to provide a deep analysis of the sustainability concepts in the circular supply chain (CSC) field and to identify research gaps and paths for future research. We conducted a search using keywords including “sustainability” combined with at least one of the keywords sustainable supply chain, green supply chain, circular supply chain, and closed-loop supply chain in the Google Scholar, ScienceDirect, and Emerald as well as the Web of Science. Mind Map Software was used to identify the gaps in the use of the CSC. The comparative investigation of the different concepts of sustainability showed that the CSC encompasses all concepts of sustainability and has a comprehensive concept that goes beyond all concepts of sustainability.
Filtro burbuja
Authors: Bruns Axel
Published: July 2022

El concepto de “filtro burbuja”, acuñado por el empresario y activista en tecnología Eli Pariser en 2011, sugiere que los motores de búsqueda y las redes sociales, junto con sus algoritmos de recomendación y personalización, son los principales responsables de la polarización social e ideológica que se vive en muchos países; ya no es posible encontrar una dieta informativa equilibrada y saludable, sino que solo vemos información que apunta a nuestros intereses establecidos y refuerza la visión del mundo que ya tenemos. Los filtros burbuja son considerados elementos decisivos en fenómenos políticos populistas como el Brexit, Trump, Bolsonaro, entre otros, y las empresas de búsqueda y redes sociales han sido duramente criticadas por no haber impedido su desarrollo. Sin embargo, la evidencia empírica de su existencia, o de la del concepto relacionado de “cámaras de eco”, es escasa; de hecho, las personas usuarias de las redes sociales y de los motores de búsqueda parecen encontrar, en términos generales, una dieta mediática sumamente centrista que es, en todo caso, más diversa que la de las no usuarias. No obstante, la recurrencia de estos conceptos en los principales medios de comunicación y en los debates políticos ha creado una realidad discursiva propia, la cual aún repercute de forma significativa en las instituciones sociales, en los medios y en las plataformas de comunicación, así como en las personas usuarias. Este artículo ofrece una revisión crítica de la idea de “filtro burbuja” y concluye que su persistencia solo ha servido para desviar la atención de la comunidad académica de áreas de investigación mucho más críticas.
Soberanía digital
Authors: Pohle Julia , Thiel Thorsten
Published: July 2022

En la última década, la soberanía digital se ha convertido en un elemento central en los discursos políticos sobre temas digitales. Aunque su popularidad ha aumentado, tanto en los países centralizados/autoritarios como en los democráticos, el concepto es aún muy controvertido. Tras investigar los desafíos a la soberanía que en apariencia plantea la transformación digital, este ensayo explora cómo la soberanía ha reaparecido como una categoría clave en relación con lo digital. Luego de sistematizar los diversos argumentos de carácter normativo sobre la soberanía digital, expone cómo, en la actualidad, el concepto se entiende más como una práctica discursiva en la política y en la normativa que como un concepto jurídico u organizativo.
