Authors: Ares-Elejoste Patricia , Seoane-Rivero Ruben , Gandarias Iñaki , Iturmendi Aitziber , Gondra Koldo
Published: July 2023

The current concerns of both society and the materials industries about the environmental impact of thermoset composites, as well as new legislation, have led the scientific sector to search for more sustainable alternatives to reduce the environmental impact of thermoset composites. Until now, to a large extent, sustainable reinforcements have been used to manufacture more sustainable composites and thus contribute to the reduction of pollutants. However, in recent years, new alternatives have been developed, such as thermosetting resins with bio-based content and/or systems such as recyclable amines and vitrimers that enable recycling/reuse. Throughout this review, some new bio-based thermoset systems as well as new recyclable systems and sustainable reinforcements are described, and a brief overview of the biocomposites market and its impact is shown. By way of conclusion, it should be noted that although significant improvements have been achieved, other alternatives ought to be researched.

New water-soluble nanocomposites with cobalt oxide nanoparticles (Co3O4NPs) in a poly(1-vinyl-1,2,4-triazole) (PVT) matrix have been synthesized. The PVT used as a stabilizing polymer matrix was obtained by radical polymerization of 1-vinyl-1,2,4-triazole (VT). The polymer nanocomposites with Co3O4 nanoparticles were characterized by ultraviolet–visible, Fourier-transform infrared spectroscopy, atomic absorption spectroscopy, transmission electron microscopy, dynamic light scattering, gel permeation chromatography, and simultaneous thermogravimetric analysis. The resulting polymer nanocomposites consist of spherical isolated cobalt nanoparticles with a diameter of 1 to 13 nm. The average hydrodynamic diameters of macromolecular coils are 15–112 nm. The cobalt content in nanocomposites ranges from 1.5 to 11.0 wt.%. The thermal stability of nanocomposites is up to 320 °C.
Interreligious Solidarity as a Benefit of Divine Hiddenness—On the Meaning of the Ambiguity of Religious Phenomena
Authors: Hołda Miłosz
Published: July 2023

Divine hiddenness appears today as one of the most important and serious religious problems. This problem has been posed most clearly by the proponents of the “argument from hiddenness”. They point to religious diversity as an important element working in the background of this argument and strengthening the force of its impact. In turn, religious diversity is seen as a result of the ambiguity of religious phenomena and the lack of conclusive testimony in favor of religious beliefs. In my paper, I pose the thesis that the ambiguity of religious phenomena can be counted among the “benefits of divine hiddenness”. This will be possible when the ambiguity of religious phenomena becomes the basis for the formation of interreligious solidarity. I define the concept of interreligious solidarity and show the theoretical aspects of this attitude. In discussing the theoretical aspect of interreligious solidarity, I draw attention to the possible role of phenomenology. I also argue that in the context of divine hiddenness, the most important question is not the one concerning the genesis of this problem (“why are religious phenomena not more unambiguous?”), but the question concerning the meaning of this problem (“what to do with the ambiguity of religious phenomena?”).

Published: July 2023

Introduction: Parkinson’s disease (PD) commonly causes speech impairments, including difficulties in expressing emotions through voice. Method: The objective of this study was to investigate gendered vocal expressions of fear, anger, sadness, and happiness for mild to moderate PD. Prosodic features (related to fundamental frequency (F0), intensity (I), speech rate, articulation rate, and number and duration of pauses) and acoustic correlates of voice quality (CPPS, jitter, shimmer, and HNR) were collected from 14 patients with PD (mean age = 69.93; SD = 7.12; 8 males, 6 females) and 13 healthy controls (HC) (mean age = 68.13; SD = 8.27; 5 males, 8 females) matched for age, sex, and years of education. The utterances were extracted from four emotional and one neutral text. The neutral utterance and the emotional utterances were compared. Intra-sex comparison (female with PD vs. female HC and male with PD vs. male HC) and inter-sex comparison (female vs. male both for patients with PD and for HC), were performed with the Mann–Whitney test. A Mann–Whitney test was also used to compare the different emotional conditions, considering sex and PD diagnosis as well. Results: No significant intra-sex differences were found for the neutral speech, but inter-sex differences emerged. Regarding emotional speech, females with PD featured lower MaxF0 than female HCs for happiness and higher intensity variability (SD I) for sadness. Utterances by females with PD had lower CPPS than utterances by HCs for anger and fear. Utterances by males with PD had lower minimum intensity (MinI) than utterances by male HCs when expressing fear. Conclusions: Emotional vocal expression in individuals with PD was found to be impaired and showed sex differences. These findings have the potential to significantly impact the quality of life of PD patients.

This work investigates the prospective usage of dried date palm residues for eosin Y and eosin B (ES-Y and ES-B) dye removal from an aqueous solution. A green synthesis route is utilized to prepare carbon nanofibers (CNFs) from date palm residues. We study the characteristics of carbon nanomaterials based on their composition and morphology. The characterization includes different types of instruments such as a Fourier-Transform Infrared Spectroscopy (FTIR), Brunauer Emmett Teller (BET), and Scanning Electron Microscopy (SEM). Batch mode experimentations are conducted and studied utilizing various significant factors such as the dose of the adsorbent, solution pH, contact time, and the initial quantity of eosin molecules as a pollutant. The dye adsorption capability improves with an increasing adsorbent dose of up to 40 mg of CNFs. The adsorption of dyes onto CNFs achieves equilibrium in around 60 h, whereas the optimal starting dye concentration in this study is 50 ppm. Further, to study the under-investigated toxic molecules’ adsorption process mechanism on the nanomaterials’ active sites, we introduce kinetic models involving pseudo-first-order, pseudo-second-order, and models based on intra-particle diffusion. Langmuir and Freundlich’s isotherms are considered to study the equilibrium isotherms, and the Langmuir isotherm model deals considerably with the attained experimentation results.

Published: July 2023

The mainstream application of the anammox process is often hindered by its long recovery phase and instability under disturbance. In this study, a lab-scale anammox sequencing biofilm batch reactor (SBBR) was rapidly recovered within 85 days by gradually increasing the influent nitrogen concentration, and the total inorganic nitrogen (TIN) removal efficiency achieved 83.44 ± 0.03%. During the recovery process, the nitrogen removal rate (NRR) increased from 0.05 to 0.34 kg/(m3·d), with the nitrogen loading rate (NLR) changing from 0.08 to 0.40 kg/(m3·d) in the anammox system. The activities of hydrazine oxidase (HZO) in the biofilm also increased from 0.17 to 10.80 μmol Cyt-c/(g VSS·s). Also, the dominant anammox genera in the biofilm were Candidatus Kuenenia and Candidatus Brocadia. The results of this study suggested that an SBBR–anammox system filled with a microbial carrier could facilitate the enrichment of anammox bacteria and contribute to performance recovery.
Reverse Engineering of Maintenance Budget Allocation Using Decision Tree Analysis for Data-Driven Highway Network Management
Authors: Amir Azam , Henry Michael
Published: July 2023

One important aspect of network-level highway management is the rational distribution of the maintenance budget to the necessary assets. However, the decision making underlying budget allocation is often unclear, making it difficult to determine whether the budget is being allocated effectively. Based on the PDCA (plan–do–check–action) approach to maintenance management, this research proposes the application of decision tree algorithm to reverse engineer the factors affecting maintenance budget allocation. Annual inspection and budget data for 3000 km of highway network were analyzed using the CART algorithm with two conceptualizations of budget allocation. Both frameworks revealed that the budget allocation was related to factors other than pavement conditions, and it was concluded that maintenance planning was primarily based on subjective considerations, rather than inspection data. This study demonstrates the combination of PDCA cycle and decision tree analysis as a valuable technique for evaluating and improving decision making in maintenance budget allocation and highway network management.

Published: July 2023

Cyber attackers are becoming smarter, and at the end of the day, many novel attacks are hosted in the cyber world. Security issues become more complex and critical when the number of services and subscribers increases due to advanced technologies. To ensure a secure environment, cyber professionals suggest reviewing the information security posture of the organization regularly via security experts, which is known as penetration testing. A pen tester executes a penetration test of an organization according to the frameworks and standardization guidelines. Security breaches of the system, loopholes in OS or applications, network vulnerabilities, and breaking data integration scopes are identified, and appropriate remediation is suggested by a pen tester team. The main aim of a penetration process is to fix the vulnerabilities prior to the attack in tangible and intangible resources. Firstly, this review work clarifies the penetration conception and is followed by the taxonomy of penetration domains, frameworks, standards, tools, and scoring methods. It performs a comparison study on the aforementioned items that develops guidelines for selecting an appropriate item set for the penetration process according to the demand of the organization. This paper ends with a constructive observation along with a discussion on recent penetration trends and the scope of future research.

Authors: Chen Hongmei , Cai Songlin
Published: July 2023

The current global situation is complex and volatile. Thus, promoting the construction of a resilient digital innovation ecosystem has become an important issue for regional innovation development. Based on panel data from 30 Chinese provinces and cities, this study empirically investigated the current situation and resilience level of China’s regional digital innovation ecosystem development using a global entropy method, a technique for order performance by similarity to the ideal solution (TOPSIS), Moran’s I, obstacles, and panel models. The results indicate that the resilience level of China’s regional digital innovation ecosystem will grow from 2011 to 2021. Spatially, it showed a spatial distribution of “coastal high–central flat–northwest depression,” with inter-regional “low coupling” and intra-regional “high cohesion” characteristics. The global Moran’s I was greater than zero, decreasing by 43.860% from 2011 to 2021, and the scope of the “high-high” quadrant and the “low-high” quadrant has been expanding and narrowing, respectively. The state and response indicators were the main obstacles to the resilience development of the regional digital innovation ecosystem, and the obstacle degree of the pressure indicators increased during the survey period. Industrial structure, regional urbanization, human capital, and digital industrialization have made significant positive contributions to regional digital innovation ecosystem resilience overall, and the drivers were regionally heterogeneous in space. Finally, this study proposes strategies for improving the resilience of regional digital innovation ecosystems, including strengthening top-level design, differentiated development, and lowering obstacles.
Optimal Dispatch Strategy for Virtual Power Plants with Adjustable Capacity Assessment of High-Energy-Consuming Industrial Loads Participating in Ancillary Service Markets
Authors: Wang Yining , Li Guangdi , Zhou Bowen , Ma Hongyuan , Li Ziwen
Published: July 2023

Amid the context of a sustainable development strategy, there is a growing interest in renewable energy as an alternative to traditional energy sources. However, as the penetration rate of clean energy gradually increases, its inherent features, such as randomness and uncertainty, have led to a surging demand for flexibility and regulation in power systems, highlighting the need to enhance the flexibility of power systems in multiple dimensions. This paper proposes a method for evaluating the adjustable power capacity of a virtual power plant (VPP), which considers the high-energy-consuming industrial load in the day-ahead to real-time stages and establishes an optimization scheduling model for auxiliary service markets based on this method. Firstly, within the day-ahead phase, the VPP is categorized and modeled based on its level of load flexibility regulation. The assessable capacity is then evaluated to establish the adjustable power range of the VPP, and the capacity of the VPP is subsequently reported. Secondly, the adjustable loads inside the VPP are ranked using the performance indicator evaluation method to obtain the adjustment order of internal resources. Finally, on the real-time scale, an optimization scheduling model to minimize the net operating cost of the VPP is established based on real-time peak-shaving and frequency regulation instructions from the auxiliary service market and solved using the CPLEX solver. The case study results show that the proposed method effectively reduces the net operating cost of the VPP and improves the stability of its participation in the auxiliary service market, which verifies the effectiveness of the proposed method.

Published: July 2023

The present study was carried out with the objective of understanding the stated interest of agricultural students in entrepreneurship and to provide an accurate research report for decision-makers, for developing entrepreneurship in India. In the present investigation, a two-stage sampling procedure was employed. In the first stage, cluster sampling was used to select the state agricultural universities (SAUs) in India. In the second stage, simple random sampling was performed to select student respondents from each SAU. Data were collected from 1797 agricultural students (second stage units) from 17 SAUs out of 74 (first stage units) studying a bachelor’s/master’s degree program and analyzed to infer outcomes related to entrepreneurship. Variables such as basic information, job interest, motivational factors, hurdles to becoming an entrepreneur, awareness about government schemes, and essential hard and soft skills were measured. Data were analyzed using frequencies, chi-square test (X2), rank-based quotient (RBQ), and binary logistic regression (BLR) analyses. The survey results revealed that “entrepreneurship” was given a lower preference by the majority; as a result, there was less motivation for students from family members. However, about 78% of students showed interest in becoming an entrepreneur. Significant areas of entrepreneurial interest for the observed students included, in order are digital agriculture < input production < marketing < farming < advisory services < dairying < financial services < poultry < developing eLearning material for farmers < and other jobs. This study demonstrates the need for Career Development Centers (CDCs), government support, and awareness and incentives regarding entrepreneurship through effective policy interventions, to protect entrepreneurs from the potential risk of business losses. This research outcome substantially contributes to the Sustainable Development Goal (SDG-4, quality education), through the soft skill development of the students, resulting in innovative agri-entrepreneurs. The present research suggested some policy implications to promote entrepreneurship more widely, which may also help other developing countries to frame potential regulations for agricultural education and entrepreneurial activities.

Published: July 2023

The rapid expansion of the cultural industry and the escalating demand for innovation have led to a growing attention on the sustainable development of cultural and creative parks. This study aims to provide a comprehensive review and prospectus of the literature on the sustainable development of these parks using CiteSpace knowledge mapping. We analyzed 662 publications from 2012 to 2023 in the Web of Science database using bibliometric methods, such as descriptive statistical analysis, network analysis, and co-citation analysis. Our findings indicate that research hotspots in the sustainable development of cultural and creative parks focus on cultural ecosystems, environmental conservation, cultural landscapes, creative tourism, park management, and urban renewal. Three primary research themes emerged: ecological service systems, assessment models, and multidimensional value. We propose five future prospects: (1) diversifying sustainable development strategies; (2) coordinating development with urban, regional, and global sustainable development goals; (3) enhancing interdisciplinary research; (4) deepening stakeholder participation; and (5) improving the evaluation index system for sustainable development. This study offers a systematic guiding framework for constructing multidimensional value for the sustainable development of cultural and creative parks, providing valuable insights for future theoretical and practical research.

This study investigated the effects of feeding cotton gin trash (CGT) to Mecheri ram lambs, as an alternate diet, on growth performance, carcass characteristics, and meat quality. A growth performance trial was conducted with thirty-two weaned Mecheri ram lambs with an average body weight of 12.64 ± 0.74 kg, which were assigned to four groups (n = eight animals in each group). The diet’s roughage part was replaced by CGT at percentages of 0% (T1), 25% (T2), 50% (T3), and 75% (T4). The growth trial lasted six months (180 days) from weaning lambs at 3–4 months until 9 months for marketing. All the animals were fed on a dry matter requirement basis at 4% of their body weight. The study revealed that the lambs fed with 50 (T3) and 75 (T4) % inclusion levels of CGT showed significantly (p < 0.01) higher total body weight gain than the T1 and T2 groups. The average daily gain of lambs in T3 (99.24 g) and T4 (105.51 g) were significantly (p < 0.01) higher than T1 (80.77 g) and T2 (83.61 g) groups. Throughout the study period, there was no statistically significant (p > 0.05) difference in the average Dry Matter Intake (DMI) (g) between the groups; however, the lambs in T4 demonstrated higher feed efficiency (7.4) than the T1 (9.3) group. The slaughter studies revealed that the lambs in the T4 followed by the T3 groups registered significantly (p < 0.01) higher hot carcass weight, dressing percentage, and meat: bone ratio than T2 and T1 group animals. The T3 and T4 groups had significantly (p < 0.05) higher weights of the liver, spleen, head, stomach, and empty intestines when compared to T1 and T2 groups; however, there was no significant (p > 0.05) difference in the weights of edible and inedible offals. In addition, there were no significant variations (p > 0.05) in pH, WHC, shear force value, sensory characteristics, and proximate composition of meat among treatment groups. The SFA levels in the T3, T4, and T2 groups were substantially (p < 0.01) greater than in the control group (T1). In contrast, the proportion of MUFA in the T1 group was significantly (p < 0.05) greater than in the T3 and T4 treatment groups. There was no significant difference in PUFA or the PUFA/SFA ratio between the treatment groups. In accordance with current research findings, the CGT can be added up to 75% of the roughage component in sheep feed as an effective unconventional supplementation, as it improves body weight, feed efficiency, and carcass characteristics in Mecheri ram lambs.

Published: July 2023

The COVID-19 pandemic has posed a significant global threat, leading to several initiatives for its control and management. One such initiative involves wastewater-based epidemiology, which has gained attention for its potential to provide early warning of virus outbreaks and real-time information on its spread. In this study, wastewater samples from two wastewater treatment plants (WWTPs) located in the southeast of Spain (region of Murcia), namely Murcia, and Cartagena, were analyzed using RT-qPCR and high-throughput sequencing techniques to describe the evolution of SARS-CoV-2 in the South-East of Spain. Additionally, phylogenetic analysis and machine learning approaches were applied to develop a pre-screening tool for the identification of differences among the variant composition of different wastewater samples. The results confirmed that the levels of SARS-CoV-2 in these wastewater samples changed concerning the number of SARS-CoV-2 cases detected in the population, and variant occurrences were in line with clinical reported data. The sequence analyses helped to describe how the different SARS-CoV-2 variants have been replaced over time. Additionally, the phylogenetic analysis showed that samples obtained at close sampling times exhibited a higher similarity than those obtained more distantly in time. A second analysis using a machine learning approach based on the mutations found in the SARS-CoV-2 spike protein was also conducted. Hierarchical clustering (HC) was used as an efficient unsupervised approach for data analysis. Results indicated that samples obtained in October 2022 in Murcia and Cartagena were significantly different, which corresponded well with the different virus variants circulating in the two locations. The proposed methods in this study are adequate for comparing consensus sequence types of the SARS-CoV-2 sequences as a preliminary evaluation of potential changes in the variants that are circulating in a given population at a specific time point.

Published: July 2023

The Bratislava region in Slovakia aims to improve its transport infrastructure by connecting the airport with the railway network. As part of the Trans-European Network for Transport project (TEN-T), an underground railway line is proposed to be constructed on both sides of the Danube River, connecting the airport in Bratislava to the Petržalka region on the river’s right side. However, underground construction is likely to have an impact on the groundwater flow regime. This construction, which will be built below the ground surface, should be built by excavating from above under the protection of sealing walls to prevent significant changes to the groundwater level regime (GWL). Therefore, a numerical model based on the finite element method (FEM) was established to evaluate the effect of the planned underground construction on the GWL, and technical measures were introduced to mitigate any potential impacts. The results of the model revealed possibilities for controlling the groundwater level in the aquifer affected by the railway structure during and after the construction.

Published: July 2023

It appears to be a challenge to keep young adolescents involved in sports, while motivation has been confirmed as a key determinant for sport participation. Consequently, the aim of this study was to get a better insight into the motivational aspects and barriers of young adolescents while paying attention to the various contexts of youth sports in the Netherlands (i.e., club, commercial and urban sports). In total, 741 young adolescents (ages 12–15) filled in a questionnaire about the motivation and barriers to participate in sports and starting a new sport. The most important motivational factor in all sports contexts appears to be ‘fun/pleasure’. Additionally, they like the atmosphere of sports, and are motivated by learning new skills and becoming better at sports. Furthermore, young adolescents value a positive atmosphere, a skilled trainer and being able to participate at their own level (with others) when starting a new sport. Identified barriers are ‘liking other activities’, ‘a lack of time’, and that ‘sport is not fun anymore’. Nevertheless, the young adolescents surveyed, even those not active in sports, generally do not experience a high degree of barriers to participate in sports. The findings provide directions for developing future interventions that improve sport participation and prevent dropout.

The article analyzes recycling of industrial waste. The main direction of construction production development is the use of new materials, reduction of material intensity, providing mechanization and industrialization of construction, increasing the operational characteristics of products and structures, the implementation of wasteless technologies in building materials at the expense of industrial waste and pollution reduction. It is important to produce concretes and mortars with enhanced physical and thermal properties for linings of thermal units operating in difficult operating conditions (high temperature, aggressive environment, contact of lining material with gases, metal melts and fluxes). Heat-resistant concretes are used in ferrous and non-ferrous metallurgy, chemical and oil refining, petrochemical, power, machine building, pulp and paper industry, in building materials The introduction of heat-resistant concrete by using new structural elements for thermal units, the most appropriate from the thermal and technological side, which is not feasible when using piece ceramic refractories. Components of heat-resistant concretes - fine grind additives and aggregates are usually made of expensive materials (chamotte, mullite, chromite, magnesite, zircon, etc.). The production of additives requires energy-intensive milling and sieving operations, which complicate and increase the cost of aggregate production technology. The replacement of scarce and expensive components by local materials and the development of technology for obtaining heat-resistant concrete on chemical binders using non-deficient materials, especially industrial waste is an important task. The prospects of using alumina-containing wastes as additives in heat-resistant concretes, which allows increasing durability and refractoriness of construction materials. The used fine-dispersed catalyst IM-2201, which is used in petrochemistry and is an alumina-chromium waste, was studied. The composition and properties of this waste and the change in the properties of concrete with the introduction of additives have been studied. It was shown that the properties of concrete change after the introduction of alumina-chromium waste in a given amount (5, 10 and 15%). Their average density, thermal strength and other properties are increased. The improvement of physical and thermal characteristics depends on the structure and new formation in the obtained samples. Concrete samples were analyzed using petrographic method and it was shown that the addition of aluminochrome waste contributes to densification of the structure due to filling the pore space with glassy mass and newly formed crystals in the cementitious mass.

On an energy basis, the problem of calculating the nonlinear deformation of structures of reinforced concrete multi-storey frames during the destruction of crossbars along an inclined section from special influences caused by structural restructuring of the structural system is solved. Analytical dependences are obtained for determining the parameters of the "moment-curvature" and "transverse force-shear" diagrams in the static-dynamic loading mode of the structures under consideration. The limiting load is determined at which, in the considered structural system of the ring, after applying a special effect in the form of a sudden removal of one of the columns, a special limiting state is achieved with the destruction of crossbars along inclined sections. The obtained design scheme of the destruction of the crossbars of the frame structures under consideration caused by the combined action of bending moments and transverse forces is compared with the destruction scheme obtained experimentally.

Perspectivas de gênero no uso dos meios de transporte e na percepção sobre as condições de mobilidade urbana
Authors: Nunes de Sousa Isabel Cristina , Bovo Peres Renata
Published: July 2023

Neste estudo, buscou-se ampliar a compreensão sobre o papel do gênero nas percepções sobre uso dos meios de transporte e sobre as condições de mobilidade urbana. O intuito era compreender, de maneira mais aprofundada, as condicionantes sociais que interferem diretamente nos padrões de deslocamento da população e perpassam indiretamente as estratégias e políticas públicas elaboradas para direcionar a escolha dos modos de transporte. Por meio da análise de respostas a um questionário, focou-se na mobilidade urbana sob uma perspectiva de gênero, especificamente nos papéis e relações sociais inerentes. Foram levantados dados primários e realizadas análises estatísticas (descritivas e inferenciais) para mensuração da influência do gênero sobre a) uso dos meios de transporte para deslocamentos diários, e b) percepções sobre as condições de mobilidade urbana. A pesquisa foi feita em uma cidade média brasileira do interior do Estado de São Paulo (São Carlos). Constatou-se uma provável relação entre o gênero dos respondentes e o uso do meio de transporte principal, visto a existência de diferenças entre homens e mulheres, sem influência constatada, entretanto, nas percepções sobre as condições de mobilidade urbana no município em questão.
A A (des)atenção à motocicleta no planejamento do sistema de mobilidade urbana
Authors: FAJGENBAUM FEIGES MANOELA , De Andrade Pereira Bernardinis Márcia
Published: July 2023

Diante do cenário brasileiro de deslocamentos intraurbanos, o modo por motocicleta vem conquistando posições cada vez mais protagonistas. A sua versatilidade e dinamismo particulares são também características que ditam o seu maior desafio: os acidentes de trânsito, os quais são extremamente onerosos à vida e aos cofres públicos. A motocicleta é peça compositora de um sistema de mobilidade urbana, o qual deve ser planejado conforme as instruções da Política Nacional de Mobilidade Urbana (Lei Federal nº 12.587/2012). O presente artigo investiga cinco planos de mobilidade, nas cinco regiões do Brasil, em municípios que apresentam altas taxas de índice de motorização para este modo de deslocamento. As discussões abordadas revelam tratativas nulas ou superficiais para a motocicleta, bem como a ausência de reflexão sobre suas causas e consequências. Ainda, com exceção dos dados estatísticos, é evidenciada a escassez de pesquisas acerca da temática. Embora eleita como principal escolha modal por parte da população, a motocicleta é comumente negligenciada pelos instrumentos de planejamento de mobilidade urbana, proporcionando consequências relevantes nos âmbitos sociais, territoriais, ambientais e econômicos das cidades.
Los caminos del Norte de Patagonia como problema historiográfico (1884-1958)
Authors: Chávez Matías , Sourrouille Marcos
Published: July 2023

Se propone abordar el problema de los caminos del sur de Río Negro y el norte de Chubut desde la segunda mitad del siglo XIX hasta mediados del siglo XX. Se argumenta que en la Patagonia septentrional, la consolidación de una vialidad estatal con una red caminera jerarquizada fue un proceso gradual y conflictivo. El objetivo es reconstruir el ordenamiento de la caminería norpatagónica durante ese período mediante el análisis de diversas fuentes, como cartografía histórica, inspecciones de tierras, informes técnicos de vialidad, documentos de prensa y expedientes de las respectivas gobernaciones. El estudio se inicia examinando las crónicas de viaje, como las de Claraz y Musters, que registraron observaciones precisas sobre las principales rastrilladas indígenas que conectaban la región. A continuación, se examina la nueva vialidad metropolitana que comenzó a imponerse a partir de las campañas militares de expansión nacional a fines del siglo XIX. Por último, se abordan las disputas entre diferentes actores y agencias que intentaron establecer jerarquías y direcciones para los caminos en las décadas siguientes.
No caminho: técnica, movimento e ritmo na formação de cães-guia
Authors: Von der Weid Olivia
Published: July 2023

As habilidades físicas e corporais de cães-guia são social e criativamente desenvolvidas por meio das relações entre cães e pessoas que acontecem em diferentes ambientes ao longo dos seus dois primeiros anos de vida. Durante as fases de socialização e treinamento, tanto o organismo do cão quanto a sua qualidade de guia estão se desenvolvendo juntos. O mesmo processo que forma o cão como guia também habilita seres humanos a uma nova identidade social e profissional – a de treinador e instrutor de cães-guia. No artigo apresento uma reflexão etnográfica sobre o processo de formação de cães-guia, uma tecnologia assistiva animal desenvolvida para facilitar a mobilidade da pessoa com deficiência visual. Focando especialmente na fase de treinamento, procuro compreender a trajetória das transformações, o desenrolar dos eventos e as mudanças de movimento que vão tornando certos cães aptos a se “graduarem” como guias. A técnica de guiar é aqui entendida como resultado de uma certa relação entre movimentos e coisas, abarcando ferramentas, corpos humanos e caninos e seus deslocamentos em diferentes ambientes.
Biografías móviles de personas con discapacidad en territorios rurales del sur de Chile; hacia una tipología de sus movilidades
Authors: Solsona-Cisternas Diego
Published: July 2023

El siguiente trabajo tiene por objetivo analizar las movilidades de personas con discapacidad en dos comunas rurales del Sur de Chile: San Juan de la Costa y las Islas de Quinchao. Utilizando un enfoque etnográfico y combinando diversas técnicas de investigación, pudimos examinar cómo estas personas se desplazan y acceden a actividades y servicios en sus respectivos territorios. Comparamos sus desplazamientos actuales con aquellos anteriores al inicio de su discapacidad, tomando en cuenta perspectivas biográficas. Además, identificamos los destinos más comunes, los modos de transporte utilizados y los motivos de sus desplazamientos. A partir de estos hallazgos, presentamos una tipología que destaca los aspectos subjetivos de las experiencias móviles de las personas con discapacidad. Finalmente, destacamos que este estudio se erige como un esfuerzo por contribuir a “leer” las discapacidades desde el enfoque de la movilidad ya que a pesar que se asume que la discapacidad es una cuestión “espacial”, a nivel latinoamericano aún es muy incipiente el desarrollo de estudios que vinculen discapacidad, movilidad y territorio desde una perspectiva experiencial.

Authors: Baltezarević Radoslav , Baltezarević Vesna , Baltezarević Ivana
Published: July 2023

The eSports industry, supported by the accelerated development of digital technologies, is becoming more and more interesting to companies, as a potential place where products and services can be advertised. Given that consumers, who follow or actively engage in playing digital games and eSports, are mostly younger men, digital marketing strategies seem like a logical choice. This paper provides several theoretical viewpoints on the function of digital marketing in the industry of eSports. The authors attempted to make this topic more accessible to professionals with expertise in this field by assessing the views of 113 respondents and highlighting the possible advantages of adopting digital marketing in the eSports industry. The aim of this study is to show that companies should focus on promoting brands on digital platforms dedicated to eSports, because such activities, which are intended for players and audiences, are generally acceptable activities of business entities. Also, when carrying out brand promotion on these platforms, it is advisable to hire credible eSports influencers on social media to recommend their brands, and ultimately, to support the spread of eWOM about the company’s brand.
Gaining New Insights into Professional Knowledge in Digital Game Art by Taking a Design Perspective
Authors: Hawey Dave
Published: July 2023

Although artists contribute a great deal to what digital game players see on the screen, there is a marked absence in the literature of direct studies of artists working in digital game development. We stress the need to understand these artists’ professional knowledge in a rich and contextualized manner, and beyond technical expertise. In this paper, we describe the design process carried out by an experienced technical artist during game preproduction. We report findings gained through ethnography/shadowing at the Montreal-based Red Barrels studio. We refer to pragmatist and constructivist theories of professional design practice to make sense of its reflective, collaborative, situated, and transactional aspects. This paper draws conclusions on three ideas: (1) the benefits of using design theory to examine design-like reflective skills in game art practice; (2) the utility of qualitative methods to construct a thorough, holistic, and contextualized understanding of professional practice, and (3) how a richer, more elaborate understanding of ‘design’ in game development points to a need for further research on the sociocultural aspects of game experience design.
The Noun Phrase in the English Sentence – Syntax Review
Authors: Jovanovska Sashka
Published: July 2023

Numerous languages allow nouns to be distinguished only by their inflections. Any prefix or suffix that conveys grammatical information is an inflection. Inflections are used to show the grammatical function of a noun (i.e., subjects take one set of endings, direct objects another, and indirect objects yet another). Modern languages like Lithuanian and Russian and ancient languages like Classical Latin and Sanskrit utilize inflections to do this. These ends also indicate whether a word is solitary or plural. This paper explains the Noun phrases in English sentences especially with the usage of English Syntax.
Produzimos narrativas complexas?
Authors: Rocha Simone Maria
Published: July 2023

Busco contribuir a necessária discussão do conceito de complexidade narrativa em seus múltiplos aspectos e que carecem de uma abordagem que seja propriamente poética. Em específico busco relacioná-la ao hibridismo de gênero enquanto esse gesto cujas características gerais poderiam nos ajudar a pensar em termos de complexidade narrativa. Com isso pretendo, ao mesmo tempo, que tal gesto me ajude a lançar luz para o que é possível chamar de narrativa complexa no contexto das séries brasileiras produzidas para streaming. Para evidenciar meu argumento, farei menções oportunas às distintas produções originais produzidas no país entre 2016 e 2021 e como elas operam com mesclas entre gêneros enquanto uma programação de efeitos emocionais compostos e, em alguns casos, ambíguos. Adoto tal hibridismo como hipótese de trabalho para avaliá-lo e compreendê-lo como complexidade possível em nossas narrativas.
A produção original da Netflix de 2013 a 2020
Authors: Penner Tomaz
Published: July 2023

Este artigo busca traçar um panorama do catálogo brasileiro da Netflix, mapeando as nacionalidades dos títulos originais disponíveis e identificando quais territórios são privilegiados em termos de incentivos para realização e quais são preteridos; quais já se tornaram tradicionalmente produtores e quais estão em ascensão. Para cumprir este propósito, são utilizadas informações consolidadas em estudos anteriores (autoria suprimida) e é dada continuidade à coleta de dados, o que ampliou o corpus da pesquisa e permitiu que fossem identificados resultados como: percepção do crescimento percentual da participação de títulos originais no catálogo geral da Netflix Brasil – o que possivelmente se repete nos demais catálogos nacionais ao redor do mundo; identificação do aumento do número de países envolvidos na produção original Netflix; e tendência de queda na participação dos Estados Unidos na referida produção, apesar de ainda ser o país de onde vem quase a metade dos títulos originais Netflix.
