Analysis of the influence characteristics and correction effect of the mine direct current method in advance detection of roadway cavities
Authors: Xie Haijun , Li Jingrui , Li Zhiqiang , Li Sheng
Published: September 2023

To ensure safety during coal mining, the DC electric method is frequently used for the advanced detection of concealed water-rich abnormal geological bodies located ahead of a drivage roadway. However, to some extent, the accuracy of the detection is influenced by the roadway cavity, resulting in a deviation from the actual location of the anomaly. To investigate this phenomenon, the principle of advanced detection based on a spheroidal physical model was analyzed via “comparative analyses” and “simulated” methods using COSMOL Multiphysics software. Following the principle of numerical simulations, the influence of the roadway cavity on the accuracy of the advanced DC detection method was introduced, and the ratio of apparent resistivity calculated from actual data to that calculated only with the roadway cavity was carried out to obtain the roadway correction coefficient. This coefficient was employed to correct the apparent resistivity data for advanced 3-D detection. Additionally, the response characteristics of the anomalies at different electrode layout locations in the roadway were discussed. The results show that the ratio method effectively corrects the influence of the roadway during advance detection using the DC electric method and simultaneously improves the resolution of geological anomalies and the accuracy of positioning. Additionally, the influence of the roadway was related to the relative positions of the electrodes along the roadway. When the electrodes are set at the junction of the floor and the sidewall, the obtained resistivity curve is less affected. Therefore, the resolutions of the anomalies are higher, and their positioning is more accurate. Furthermore, a practical application of the ratio method indicated that the corrected curves reflected the geological anomalies better.

Authors: Ávila Molina Angélica María
Published: September 2023

La lectoescritura en lengua indígena ha sido usada para aumentar su prestigio y construir un registro duradero, así como medio de aprendizaje de la lengua, mientras que en español facilita el éxito académico y el acceso al trabajo. En el mundo globalizado y urbano, permite la participación, el diálogo social y el disenso. Es necesario generar procesos de aprendizaje de literacidad que no signifiquen el debilitamiento de las lenguas indígenas ni de su oralidad. El objetivo fue formular participativamente recomendaciones para la enseñanza de la lectoescritura en lengua wounmeu (ISO 639-3 noa) y en español acordes con la visión de mundo wounaan, con el fin orientar la toma de decisiones en la construcción del Proyecto Educativo Comunitario y la planificación lingüística en literacidad en el escenario urbano. Para esto, se exploran las posturas sobre la literacidad en las comunidades indígenas y se presentan el proyecto, las prácticas lingüísticas de la comunidad, la explicación de las recomendaciones, un balance del proceso y las conclusiones.
Perfiles geomorfológicos complejos aplicados en las subcuencas de los ríos Huacapa y Huajapa, Guerrero, México

Published: September 2023

En este artículo se presentan perfiles geomorfológicos complejos que incluyen diferentes índices geomorfológicos, los cuales se localizan en la zona norte de la Ciudad de Chilpancingo, Guerrero-México, en los límites de las subcuencas del río Huacapa y río Huajapa. Para la creación de los índices se generó un estudio morfométrico (hipsométrico, pendientes, orden de drenaje, densidad de disección, y profundidad de disección, aunado a la caracterización geológica), los cuales fueron contrastados en dos tipos de perfiles: longitudinales y transversales con el fin de reconocer relaciones y diferenciaciones espaciales a nivel cuenca. Los resultados obtenidos indican que la densidad de disección va de mediana a baja en el perfil longitudinal y en el transversal presenta un valor de bajo a muy bajo; en la densidad de profundidad de disección se presentan valores medios en ambos perfiles. La formación geológica corresponde al terciario neógeno. De acuerdo con la interpretación de los perfiles geomorfológicos se concluye que en la zona se presenta una zona de rebajamiento o nivelación del relieve por la acción de los agentes exógenos. Aunado a esto en el punto de intercepción de ambos perfiles muestra un movimiento tectónico regional positivo, concluyendo así que la zona se encuentra en una fase de transición entre el relieve joven a uno más antiguo ya modelado.

Authors: Bermúdez Ayala María Alejandra , Bachiller Moscoso Claudia Patricia , Fuentes López Héctor Javier
Published: September 2023

En Colombia, durante la cuarentena por COVID-19, aproximadamente cada diez minutos se realizó una denuncia por violencia intrafamiliar. El presente artículo estima la probabilidad de violencia física de la mujer en Bogotá en el marco de aislamiento obligatorio. Esta estimación se realiza a partir de modelos econométricos probabilísticos tipo logit, donde se miden diferentes variables socioeconómicas de las mujeres víctima de violencia física en Bogotá, como: localidad de residencia, edad, estado civil, ocupación, tipo de relación con su agresor, estrato socioeconómico, nivel de escolaridad y si la violencia ocurrió en un espacio privado o público. De este modo, se evidencia que las mujeres que no cuentan con ingresos propios y habitan en zonas de estrato socioeconómico más bajo de la ciudad tienen una mayor probabilidad de ser víctimas de violencia física. Por su parte, se encuentra que las localidades de mayor probabilidad de este tipo de violencia son: Rafael Uribe Uribe, Teusaquillo y Ciudad Bolívar. Igualmente, se evidencia que estar en un espacio privado aumenta la probabilidad de ser víctima de violencia, por lo que en el confinamiento aumentó el riesgo de sufrir violencia física en los hogares.

Published: September 2023

La pandemia global de COVID-19 ha hecho visibles múltiples fenómenos que permanecían latentes, pero no se habían manifestado en la cotidianidad de la vida urbana. A partir del acontecimiento que supuso la irrupción de este nuevo virus, surge la consolidación de una vida esencialmente digital que modifica las dinámicas sociales en un mundo de por sí hiperdigitalizado. Este artículo analiza la reciente pandemia en consonancia con la potenciación del uso de redes sociales y su impacto en diferentes esferas de la vida cotidiana de algunos jóvenes en la ciudad de Bucaramanga durante el año 2020, centrando la atención en el fenómeno de la infodemia y su vínculo con la salud mental. La metodología utilizada es cualitativa con orientación interpretativa. El enfoque hermenéutico guía el análisis de la información, la cual proviene de la experiencia de 80 estudiantes del programa académico de Historia y Archivística de la Universidad Industrial de Santander. Se concluye que la pandemia, junto con los fenómenos digitales que se manifestaron a partir de ella, influyó de forma decisiva en la salud mental de los jóvenes que participaron en el estudio, quienes comprendieron este evento como un acontecimiento desestabilizador de la vida cotidiana que dio nuevos sentidos a la habitual concepción de “normalidad”.
Os movimentos socioterritoriais e a luta contra a fome durante a pandemia do novo coronavírus no Brasil
Authors: Jorge Aline Albuquerque , Machado Angela dos Santos
Published: September 2023

No Brasil, a classe trabalhadora vem perdendo direitos e sofrendo com a descontinuidade de políticas públicas. As ações do governo atual têm refletido no aumento da extrema pobreza e, consequentemente, no retorno do país ao mapa da fome. A pandemia do novo coronavírus agravou essa conjuntura. É nesse contexto que as doações de alimentos realizadas pelo Movimento dos Trabalhadores Rurais Sem Terra (MST) e outros movimentos socioespaciais e socioterritoriais se configuram em importantes ações de solidariedade voltadas ao combate à fome. Este trabalho objetiva analisar criticamente e dimensionar as doações de alimentos do MST. Para isso, foram realizadas pesquisa bibliográfica e entrevista semiestruturada. Também foram levantadas e sistematizadass notícias divulgadas pelo MST, referentes às doações realizadas no período de março de 2020 a março de 2021. A pesquisa aponta que as doações de alimentos são uma forma de luta e de denúncia da ausência do poder público e expressam solidariedade. Essas ações reafirmam a necessidade da reforma agrária.
The Connection between Power and the People in the Mari, Mordovian and Chuvash ASSR in the mid-1950s – 1980s (On the Example of the Councils of Ministers of Autonomous Republics)
Authors: Uchvatov Pavel S.
Published: September 2023

Introduction. This article describes the feedback between the Soviet people and executive authorities of the autonomous republics from the mid-1950s to the 1980s on the example of activities of the Councils of Ministers of the Mari, Mordovian and Chuvash Autonomous Soviet Socialist Republics. The research focuses on the reaction of the Councils of Ministers and their subordinate bodies to letters, received from citizens.

Materials and Methods. The study was based on materials of the State Archive of the Republic of Mari El, the State Historical Archive of the Chuvash Republic, and the Central State Archive of the Republic of Mordovia. In the work were used the content analysis, the concrete historical, the historical-systematic and the historical-comparative methods based on the on the fundamental principles of historical study – historicism, objectivity, systemacity.

Results. The most common form of everyday communication between the Councils of Ministers of ASSR and the society was the submission by citizens of applications, appeals and petitions, which raised the various issues. The analysis of the activities of the Councils of Ministers of the Autonomous Republics revealed problems related with the consideration of citizens’ appeals. The reaction of the Councils of Ministers to criticism of shortcomings in the organization of accounting for incoming letters, control of subordinate authorities, as well as the personal reception of citizens is considered. The most pressing issues with which Soviet people appealed to regional governments were identified.

Discussion and Conclusions. Despite significant shortcomings in the system of consideration of complaints and appeals of citizens, the Councils of Ministers, as the central bodies of state administration of the republics, as a whole performed a number of important communicative functions between the government and society. The following are the most basic points: 1) the citizens had the opportunity to solve various everyday, social, economic issues using the appeal to the authorities; 2) the regional authorities received representations about the problems of concern to the Soviet people, so that timely action could be taken; 3) Councils of Ministers of ASSR and subordinate bodies acted as a link between the people “on the ground” and the highest authorities.
“Let Someone Who is Not a Mathematician Not Read Me” (Natural-Scientific Views in the Works of Leonardo da Vinci)
Authors: Belkin Aleksey I. , Chashina Zhanna V.
Published: September 2023

Introduction. It is noted the originality of Leonardo da Vinci’s natural-scientific views in the context of the Renaissance. The objectives of the article are outlined: the systematization of Leonardo’s natural-scientific views, the identification of methods used by him to cognize the reality, the analysis of the set of social conditions that influenced the formation of the thinker’s views. It is also indicated the relevance of the researched argument; the object and subject of the study are determined.

Materials and Methods. It is indicated that the main source used in the article are the notes of Leonardo, reflecting his ideas about nature. The methods used in the study are related to the specifics of this source: a concrete historical approach, a comparative historical method, logical and textual methods.

Results. The circumstances that gave rise to an interest in natural-scientific problems are indicated – painting and its interpretation as a reflection of the real world, on the one hand; good mathematical training received by Leonardo in his youth, on the other. It is proved, using primary sources, that Leonardo da Vinci considered experience to be the main method of cognition, and the ultimate goal of cognitive activity was the practical application of knowledge. The peculiarity of the humanistic orientation of Leonardo’s thought is revealed. On the basis of primary sources, the thinker’s ideas about nature, human, and the purpose of science are revealed. It is shown how Christian ideas and the humanistic Renaissance view were combined in a peculiar way in the views of the thinker. Attention is drawn to the inconsistency of Leonardo da Vinci’s relationship with Christianity.

Discussion and Conclusion. It is shown the significance of Leonardo’s philosophical views, his role in the history of philosophy as a predecessor of the empiricist philosophers of Modern Time. It is noted that the comprehensive activity of the thinker, in fact, embodied the ideal of a person, great creative opportunities that feed, firstly, the desire to fully know the world and, secondly, the awareness of the usefulness of their activities for others. It is noted that the cultivation of these motivations has a huge educational potential in our time.
Immunisation of chickens with commercial anticoccidial vaccines Immucox® and Livacox® showed varied protection against a virulent Eimeria tenella local isolate and Houghton strain

Published: September 2023

Coccidia is an ubiquitous intestinal protozoan of poultry that invade the mucosa and induce epithelial cell necrosis and inflammation. To assess the pathogenicity of two commercial anticoccidial vaccines against a local isolate of Eimeria tenella, ninety (90) day-old dominant black chicks were assigned to 9 groups of 10 birds each. Immunisation was done at 5 days of age by oral gavage. Infection was done with 1.7×104 E. tenella of either Houghton strain (H-strain) or local isolate (L-isolate) at 4 weeks of age. Increased pathogenicity of the local isolate was observed, as it produced a more severe gross pathologic lesion score than the Houghton strain in unvaccinated but infected groups of chickens 6 days post-infection (dpi). The high virulence and pathogenicity of the local E. tenella was responsible for the differences in the severity of clinical signs, gross and microscopic lesions observed between the H-strain and L-isolate infected groups. The histopathology showed that the vaccinated groups, infected with the H-strain of E. tenella, did not show presence of oocysts or schizonts by 6 dpi. The successful immunogenicity and effectiveness of these two vaccines as measured by the histopathologic lesions and the presence of oocysts in the enterocytes of the caecal crypts of these chickens were reduced in vaccinated and L-isolate infected groups. The findings in the L-isolate groups were setbacks to the use of live attenuated and non-attenuated anticoccidial vaccines for control of coccidiosis and in particular, caecal coccidiosis in chickens reared in environments dominated by virulent E. tenella.

The present study was conducted to examine the changes in calcium and phosphorus levels during Staphylococcus aureus (S. aureus) infection in rabbits. The experimental procedures were carried out with 12 male New Zealand white healthy rabbits, divided into two equal groups - the experimental group (n=6, rabbits infected with S.aureus) and the control group (n=6, uninfected animals). Blood samples were collected at 0 hours before infection, as well on 6, 24, 48, 72 hours and 7, 14 and 21 days after the infection. The amount of calcium in infected rabbits decreased significantly by the 48-th hour (p<0,01) after infection with bacterial suspension. A significant increase of phosphorus in the experimental group was observed at 24 hours and on the 7-th day after infection.

Authors: Nizamov N. , Iliev P.
Published: September 2023

The current study was performed to assess the most common clinical symptoms and hemato-biochemical alterations in goats naturally infested with sucking and biting lice. A total of 4599 goats were included in the clinical investigation. The changes in concentrations of some hematological and biochemical parameters were evaluated using 20 naturally infested animals divided into 2 equal groups – group 1 (infested with Bovicola caprae) and group 2 (infested with Linognathus stenopsis). Blood samples were collected before the treatment with Eprinomectin and on the 30th and 60th-day post-treatment (DPT). After sampling, the blood was examined for changes in the complete blood cell count including RBC, HGB, HCT, RBC indices (MCV, MCH, MCHC, RDW), WBC, leukocyte differential count as well as some biochemical parameters (Ca, P, Fe, total protein, albumin, bilirubin, ASAT, ALAT, AP). Clinical demonstrations in infested goats were not specific, represented with rubbing, scratching, broken hairs, alopecia, skin secretion, inflamed lesions (papules), crusts, and keratinization. The changes found in the hematological and biochemical parameters were normocytic hypochromic anemia (p˂0.001) and hypoferremia (p˂0.01) in the goats infested with sucking lice (L. stenopsis) and leukocytosis (p˂0.001), hyperproteinemia (p˂0.001) and hyperalbumineamia (p˂0.05) in the animals infested with biting lice (B. caprae). All changed parameters have returned to the reference ranges on the 30th and 60th DPT.
What drives global competitiveness in the European Union countries?
Authors: Marčeta Milja , Bojnec Štefan
Published: September 2023

This paper examines the effect of factors of national competitiveness measured by the Global Competitiveness Index (GCI). It aims to identify the key factors that determine GCI of the European Union (EU-28) countries. We observe the composite indicator of GCI and the 12 factors of competitiveness in the period of 2008–2019 focusing on the links between the GCI and the factors of institutions, infrastructure, macroeconomic environment and its stability and market size. The GCI is determined using correlation and regression analyses and Structural Equation Model. A significantly positive relationship with the GCI is confirmed for institutions, infrastructure, macroeconomic environment and stability, labour market efficiency, market size, technological readiness in terms of information and communication technologies, and business sophistication and dynamism, but not for higher education and training and financial market development. The quality institutions are confirmed as a fundamental positive factor for the GCI together with macroeconomic environment and stability and market size. The study contributes with an empirical analysis that confirms the relationship between the selected factors of competitiveness and the GCI in the EU-28 countries.
The economic and social determinants of vaccine hesitancy in Romania during the COVID-19 pandemic
Authors: Boga Balázs , Markó Balázs , Rácz Béla-Gergely
Published: September 2023

The COVID-19 pandemic affected all countries both in social and economic dimensions. Currently, vaccination is considered to be one of the most efficient solutions which can stop the further spread of the virus. Therefore, the paper aims to understand the factors that determined the social approval of the COVID-19 vaccines in Romania. To get a detailed picture on the situation, we looked not only at economic variables, but also at social and demographic components. Accordingly, the findings of the analysis list the variables that significantly influence the vaccination rate nationwide. The social approval (or the refusal) of these shots is a complex issue, thus it is essential that policymakers make decisions based on scientific evidence. The practical relevance of the paper lies in the two policy implications suggested (i.e., transparent and predictable policymaking and adjustments on the level of the education system in the long run for similar situations), which also highlight the importance of evidence-based decision-making processes in public health. Our analysis method consists of multivariate cross-sectional OLS regressions.

Published: September 2023

This investigation analyses the academic research development over the last 30 years on behavioural finance in the emerging markets. We use Web of Science database to collect the bibliographic material and a VOS Viewer software to identify similarities by using bibliometric techniques. The results show a significant growth of research in this area, especially after the subprime crisis and highlights the emergence of sub areas of interest to researchers which have arisen in a natural fashion and without a previously defined orientation. There is still no consensus in the literature regarding the causes of this phenomenon and new questions emerge to expand research on herd behaviour in the emerging markets.

Published: September 2023

Background

Mansonellosis is a widely neglected helminth disease which is predominantly observed in tropical regions. This study was conducted to assess potential associations of the prevalence of circulating Mansonella perstans-specific cell-free DNA in human serum and HIV infection in Ghanaian individuals.

Methods

For this purpose, serum samples obtained from Ghanaian HIV-patients (n = 989) and non-HIV-infected Ghanaian control individuals (n = 91) were subjected to real-time PCR targeting the ITS-(internal transcribed spacer-)2 sequence of M. perstans and Mansonella sp. Deux.

Results

Mansonella-specific cell-free DNA was detected in serum samples of only 2 HIV-positive and 0 HIV-negative individuals, making any reliable conclusions on potential associations between HIV and mansonellosis in tropical Ghana unfeasible.

Conclusions

Future epidemiological studies on hypothetical associations between mansonellosis and HIV infections should focus more specifically on high-endemicity settings for both Mansonella spp.-infections and HIV-infections, include higher case numbers and be based on real-time PCR from whole blood rather than from serum, in which only circulating parasite DNA but no more cell-bound parasite DNA can be detected. However, the study did not show associations of HIV infections in Ghanaian individuals with Mansonella worm loads high enough to detect cell-free Mansonella DNA in serum by PCR.
Mutual Influence of Intellectual Capital and Information Technologies of Management
Authors: Sokolov Boris , Verzilin Dmitry , Maximova Tatyana , Zhang Min
Published: September 2023

To date, there is a generally accepted idea of intellectual capital, and approaches have been developed to measure it at the micro and macro levels. Methods of patent analytics for the analysis of technological trends have been developed. At the conceptual level, it is known that there is a mutual influence of intellectual capital and technological trends, but there are no methodological developments for quantifying such influence using data from various sources. The purpose of the study was to quantify the mutual influence of national intellectual capital and modern management information technologies at the macro level. The mathematical foundations for the distinction of the components of intellectual capital and technologies were considered. The hypothesis about the statistical significance of the mutual influence of intellectual capital and management information technologies was confirmed. The dependence was approximated by linear regression of the intellectual capital index on the logarithm of the country's patent activity index in the field of IT management methods, which can be interpreted as a slowdown in the growth of the intellectual capital index when a certain level of patent activity is reached. It has been established that the more developed the economy, the higher the level of intellectual capital and the higher level of dissemination of IT management methods. China and India are clear exceptions to this pattern. China, which is an upper-middle-income country, demonstrates higher than the countries of its level of economic development, interconnected values of the index of intellectual capital, and the prevalence of IT-management methods. India, ranked 3rd among lower-middle-income countries, has commensurate rates of development of intellectual capital and the spread of IT-management methods with upper-middle-income countries. Further research may be related to testing hypotheses about quantitative relationships between intellectual capital and technological development via the proposed method. It is necessary to detail the identified dependencies by IPC codes and components of intellectual capital and identify dependencies for other technological areas.
On Stochastic Optimization for Smartphone CPU Energy Consumption Decrease
Authors: Pelogeiko Makar , Sartasov Stanislav , Granichin Oleg
Published: September 2023

Extending smartphone working time is an ongoing endeavour becoming more and more important with each passing year. It could be achieved by more advanced hardware or by introducing energy-aware practices to software, and the latter is a more accessible approach. As the CPU is one of the most power-hungry smartphone devices, Dynamic Voltage Frequency Scaling (DVFS) is a technique to adjust CPU frequency to the current computational needs, and different algorithms were already developed, both energy-aware and energy-agnostic kinds. Following our previous work on the subject, we propose a novel DVFS approach to use simultaneous perturbation stochastic approximation (SPSA) with two noisy observations for tracking the optimal frequency and implementing several algorithms based on it. Moreover, we also address an issue of hardware lag between a signal for the CPU to change frequency and its actual update. As Android OS could use a default task scheduler or an energy-aware one, which is capable of taking advantage of heterogeneous mobile CPU architectures such as ARM big.LITTLE, we also explore an integration scheme between the proposed algorithms and OS schedulers. A model-based testing methodology to compare the developed algorithms against existing ones is presented, and a test suite reflecting real-world use case scenarios is outlined. Our experiments show that the SPSA-based algorithm works well with EAS with a simplified integration scheme, showing CPU performance comparable to other energy-aware DVFS algorithms and a decreased energy consumption.
Information Security Risk Analysis in Food Processing Industry Using a Fuzzy Inference System
Authors: Asfha Amanuel , Vaish Abhishek
Published: September 2023

Recently, different attempts have been made to characterize information security threats, particularly in the industrial sector. Yet, there have been a number of mysterious threats that could jeopardize the safety of food processing industry data, information, and resources. This research paper aims to increase the efficiency of information security risk analysis in food processing industrial information systems, and the participants in this study were experts in executive management, regular staff, technical and asset operators, third-party consultancy companies, and risk management professionals from the food processing sector in Sub-Saharan Africa. A questionnaire and interview with a variety of questions using qualitative and quantitative risk analysis approaches were used to gather the risk identifications, and the fuzzy inference system method was also applied to analyze the risk factor in this paper. The findings revealed that among information security concerns, electronic data in a data theft threat has a high-risk outcome of 75.67%, and human resource management (HRM) in a social engineering threat has a low-risk impact of 26.67%. Thus, the high-probability risk factors need quick action, and the risk components with a high probability call for rapid corrective action. Finally, the root causes of such threats should be identified and controlled before experiencing detrimental effects. It's also important to note that primary interests and worldwide policies must be taken into consideration while examining information security in food processing industrial information systems.
Kematangan Beragama Dalam Masa Pandemi Covid-19: Telaah Sosiologis atas Nasihat Imam Besar Istiqlal Nasaruddin Umar
Authors: Lestari Puspita Ayu
Published: September 2023

The pandemic Covid-19 outbreak has hit the economic, social, cultural, and mental health of some residents.. The effects of the outbreak not only make people have to pay more attention to their health. But it is also required to be able to reorganize social and improve mental and spiritual endurance. In these situation, religion forms a human dependence on the dimension of divinity, especially when the man experiences a terrible disaster and closes the door to rationality. Looking at the frenzy and diverse public responses, this paper tries to discuss religious maturity during the covid-19 pandemic by studying the advice of high priest Istiqlal Nasaruddin Umar. Through the theory of W.H. Clark, regarding the four criteria for religious maturity, this paper argues that one's religious maturity can be seen from its application in personal life and those around them during the Covid-19 pandemic.

During the COVID-19 pandemic, there has been an increase in anxiety and distress in many populations. They particularly affected selected professional groups, e.g. teachers. Among the strategies for coping with anxiety and stress, interventions using music as a tool to reduce tension are showing promising results. For the purpose of this study, a therapeutic intervention protocol using various music-based activities was constructed. A pilot study was carried out to initially assess the effectiveness of the intervention, and – on the other hand – to check the feasibility of the proposed experiment in terms of methodology and practice. The study involved 13 participants (n = 13); a mixed study design with a triple-repeated measures was used (the GAD-7 Generalized Anxiety Questionnaire). The results were interpreted both in an individualized and experimental perspective, with a statistical analysis (ANOVA, Student’s t-test). They suggest that the original musical intervention contributed to the reduction of the level of anxiety in the time course. Due to the size of the sample and the pilot design of the study, the results should be treated with caution.
Usability and User Experience on Secondhand Fashion Digital Platforms: A Comparative Study
Authors: Dourado Pedro
Published: September 2023

With the fashion industry's negative impact already widely acknowledged, we've seen new ways of consuming and investing in the circular economy system. After establishing the importance of new technologies in today's fashion consumption, the spotlight is now on the role of e-commerce in the advent of circularity. This article presents a comparative analysis on four second-hand fashion e-commerce websites available in Portugal, with the goal of understanding the importance of usability and user experience for e-business and identifying the best and worst interaction design practices. With implications for academia as well as the fashion and communication industries, this study demonstrates that the analyzed platforms do not have structural issues, becoming examples to be considered for their good performance – which may be the cause for increased interest in the circular economy – and exposing guidelines for future research.
A multimodal analysis for an updated vision of women in music videos
Authors: Sánchez-Vizcaíno María-Carmen , Cancelas-Ouviña Lucía-Pilar , Fonseca-Mora M.Carmen
Published: September 2023

A democratic society is characterised by the respect accorded to the dignity and rights of all its members. These values are also transmitted by high-consumption media cultural products such as music videos. This article discusses the representation of women in music videos published in Spanish on music broadcast platforms in 2019 in order to observe the multimodal discourses to which our society is exposed. After identifying a total of 4197 videos, 47 of the highest emission frequencies were extracted. Using the qualitative data analysis programme Atlas.ti, narrative, linguistic and visual resources, as well as cinematographic components, were analysed. The results reveal clear attacks on female dignity. Normalised sexist violence is observed in songs on the Hispanic market, where women are commodified as sexual objects on both audio-visual and linguistic levels. Hierarchical relationships are also shown, which position women on an inferior plane. In conclusion, commercial channels broadcast music videos from the Hispanic market that violate feminine dignity.
MERCADO DE TRABALHO E CURRÍCULO: PERFIL DE ESTUDANTES DE CIÊNCIAS SOCIAIS E PROCESSO FORMATIVO NO INSTITUTO DE FILOSOFIA E CIÊNCIAS HUMANAS DA UNICAMP
Authors: Santos Isolda Santiago dos
Published: September 2023

Ocorreram mudanças significativas no mercado de trabalho brasileiro para as ciências sociais na última década, principalmente levando em consideração a Reforma do Ensino Médio, o surgimento de novas atuações profissionais e os desinvestimentos em ciência e educação do período de 2013 a 2022. As possibilidades de cientistas sociais se inserirem no mercado de trabalho são bastante variadas, mas ainda há uma concepção curricular bastante voltada à formação de professores da educação básica e pesquisadores acadêmicos nas graduações da área. Em minha pesquisa de mestrado sobre os ingressantes de Ciências Sociais da Universidade Estadual de Campinas, interessava não só conhecer os estudantes, mas também aprofundar a compreensão acerca do currículo do curso e como se expressam a permanência e a mudança das disciplinas oferecidas nos últimos dez anos. Para a realização deste trabalho foram analisadas as ementas disponibilizadas pelo site do Instituto de Filosofia e Ciências Humanas (IFCH) de 2013 a 2023, além dos dados divulgados anualmente pela Comissão Permanente para os Vestibulares sobre os inscritos no vestibular da Unicamp. A partir da análise, foi possível verificar que o IFCH oferece semestralmente muitas disciplinas eletivas voltadas principalmente a conteúdos teóricos e, mesmo nos casos das disciplinas de teor mais prático, focadas mais especificamente em produção acadêmica, não apresentando número expressivo de eletivas que visam, a princípio, um mercado de trabalho mais amplo e fora da universidade.

Quais tipos de questões são mais suscetíveis à persuasão ou polarização por meio de heurísticas fornecidas por elites partidárias? A hipótese central a ser testada neste artigo propõe que questões políticas com alto valor identitário e distintivo favorecem o discernimento, tornando-se, assim, menos suscetíveis à persuasão e polarização por elites políticas (H1). Os dados utilizados neste estudo foram extraídos de um banco de dados experimentais com uma amostra probabilística do eleitorado norte-americano. Para investigar H1, analisamos a relação entre os efeitos das heurísticas polarizantes encontradas nos tratamentos e a diferença nas médias de apoio a dez questões políticas entre republicanos e democratas. A hipótese foi confirmada pelos resultados, tanto em relação à heurística fornecida pelo partido republicano quanto pela fornecida por Donald Trump. Os achados fortalecem a ideia de um sistema democrático que, de fato, representa os valores do eleitorado e evidenciam claramente um limite no impacto das lideranças políticas sobre as preferências dos eleitores. No entanto, essa persuasão ou polarização ainda pode ser problemática mesmo centradas em questões laterais, que podem ser de extrema relevância.
Racismo contra os povos indígenas: principais agentes e formas de manifestação (de 2003 a 2022)
Authors: Ribeiro Rodrigo Barbosa
Published: September 2023

O racismo contra os povos indígenas é um fenômeno com crescente notoriedade, dadas as denúncias e análises a indicar como povos nos mais variados contextos socioculturais são afetados. O presente trabalho pretende construir um quadro geral sobre esse fenômeno, mediante a análise dos episódios de racismo reunidos nos relatórios sobre a "Violência contra os povos indígenas", uma série de publicações a cargo do Conselho Indigenista Missionário (CIMI). Com volumes lançados anualmente, os relatórios compilam os casos desde 2003, totalizando 362 ocorrências nos 20 anos do levantamento. O trabalho consistiu na leitura, análise e sistematização dos casos, identificando os personagens e contextos envolvidos nesses atos. Embora esses episódios não expressem a totalidade das práticas racistas perpetradas contra os povos indígenas, tais ocorrências permitem vislumbrar os principais agentes, locais de ocorrência e formas de manifestação desse fenômeno, permitindo constatar quais povos sofreram ações racistas, bem como quais agentes os praticaram e em quais localidades e/ou contextos relacionais. Em seguida, buscou-se averiguar quais foram as principais formas assumidas pelas ações racistas, relacionando essas manifestações com os agentes e situações previamente identificados. Tais dados mostraram que o racismo não é algo episódico, pois se constitui em um elemento estruturante das relações sociais vivenciadas pelos povos indígenas no Brasil atual, se espraiando pelos mais variados contextos socioculturais e marcando as relações coloniais vigentes.
ONE-DIMENSIONAL IMPULSIVE PSEUDOPARABOLIC EQUATION WITH CONVECTION AND ABSORPTION

Published: September 2023

We study the initial-boundary value problem for the one-dimensional Oskolkov pseudoparabolic equation of viscoelasticity with a nonlinear convective term and a linear absorption term. The absorption term depends on a positive integer parameter n and, as n → + ∞ , converges weakly * to the expression incorporating the Dirac deltafunction, which models an instant absorption at the initial moment of time. We prove that the infinitesimal initial layer, associated with the Dirac delta function, is formed as n → + ∞ , and that the family of regular weak solutions of the original problem converges to the strong solution of a two-scale microscopic-macroscopic model. The main novelty of the article consists of taking into account of the effect of convection. In the final section, some possible generalizations and applications are briefly discussed, in particular with regard to active fluids.

Derecho a la energía desde los derechos humanos: transición profunda hacia viviendas adecuadas, un ambiente sano y modos de vida dignos
Authors: Hessling-Herrera Franco-David , Garrido Santiago-Manuel , Gonza Cinthia-Natalia
Published: September 2023

Con el cambio climático en ciernes y un contexto internacional que propende a la transición energética, el derecho a la energía reclama un espacio de mayor protagonismo en el ámbito internacional y en los sistemas de protección de derechos humanos, para inclinar ese proceso hacia una transición profunda. De ahí que este trabajo tenga como objetivo aportar a los debates y las relaciones posibles entre transición energética y derechos humanos. Se emplea una metodología de derecho comparado, con un enfoque hermenéutico, de descripción densa. Se recorre el concepto de derecho a la energía en la Agenda 2030 y sus objetivos de desarrollo sostenible, al igual que las referencias en otros instrumentos de los sistemas de protección de derechos humanos -tanto el universal como los regionales-. A partir de ese recorrido comparativo, se concluye que el Sistema Interamericano de Derechos Humanos está a la cabeza de la literatura jurídica sobre derecho a la energía, sentando doctrina para evitar el encorsetamiento de la transición energética.
Disposición a pagar por hoteles con ecocertificaciones en el contexto mexicano. Estudio comparativo a través de precios hedónicos

Published: September 2023

Las estrategias medioambientales en el turismo tienen como objetivo reducir el impacto negativo de este sector, a la vez que buscan alcanzar efectos positivos sobre su competitividad y rentabilidad. Sin embargo, aún existe un vacío de investigación en la literatura académica sobre la conexión entre las ecocertificaciones y los precios que los clientes pueden pagar por ese tipo de servicio. El artículo analiza la disposición a pagar de los huéspedes por habitaciones en hoteles amigables con el medio ambiente en México. Se centra en tres de los estados con mayor número de establecimientos hoteleros del país y con más ocupación turística: Quintana Roo, Veracruz y Jalisco. Se evalúan las diferencias entre la disponibilidad a pagar de los huéspedes por hoteles con ecocertificación entre estados, teniendo en cuenta la categoría del establecimiento. Se utilizan modelos de precios hedónicos para evaluar el efecto de la ecocertificación, junto a diferentes atributos del hotel. En el precio de una habitación, se recabó información de la base de datos Trivago y se estimaron las ecuaciones teniendo en cuenta técnicas de panel de datos. Los resultados muestran un efecto significativo en la disposición a pagar por hoteles con ecocertificaciones, con diferencias entre estados y categorías. Las limitaciones de esta investigación son el tiempo de recolección de datos y los lugares de aplicación.

Authors: Hurtado Montes Bibiana
Published: September 2023

Objetivo: evaluar el nivel de actividad física, horas sedente e índice de masa corporal (IMC) en una comunidad universitaria asociados al aislamiento obligatorio decretado en razón a la pandemia por COVID-19. Metodología: estudio descriptivo, transversal en trabajadores, docentes y estudiantes con un rango de edad de 18 a 59 años, llevada a cabo entre febrero y abril del 2021 con un muestreo por conveniencia. Se determinó el índice de masa corporal y se aplicó el Cuestionario Internacional de Actividad Física versión corta avalado para Colombia. Resultados: se evaluaron un total de 52 personas, 35 mujeres (67,3 %) y 17 hombres (32,7 %), edad media de 37,6 años ± 11,4, IMC medio de 25,9 kg/ m² ± 3,8. El nivel del IMC mostró un exceso de peso en el 67,9 % del grupo de 39 años o más; en los menores solo el 4,2 % mostró niveles en obesidad. No se encontraron personas con nivel bajo peso. En el 57,7 % de los participantes se encontró bajo nivel de actividad física, 15,4 % en el nivel moderado y 26,9 % con un nivel de actividad física alta. Las horas sedentes de los mayores se encontró en 8,4 horas por día. Conclusiones: los cambios en el estilo de vida asociados al aislamiento obligatorio, impactaron de forma negativa en el nivel de actividad física, en el IMC y en número de horas sedente a los integrantes de la comunidad universitaria.
