Blue Infrastructures: An Exploration of Oceanic Networks and Urban–Industrial–Energy Interactions in the Gulf of Mexico
Authors: Mehan Asma , Casey Zachary S.
Published: September 2023

Urban infrastructures serve as the backbone of modern economies, mediating global exchanges and responding to urban demands. Yet, our comprehension of these complex structures, particularly within diverse socio-political terrain, remains fragmented. In bridging this knowledge gap, this study delves into “boundary objects”—entities enabling diverse stakeholders to collaborate without a comprehensive consensus. Central to our investigation is the hypothesis that oceanic infrastructural developments are instrumental in molding the interface of urban, industrial, and energy sectors within marine contexts. Our lens is directed at the Gulf of Mexico, which is distinguished by its industrial depth and expansive marine grid. We highlight the Gulf Intracoastal Waterway’s (GIWW) paramount role in regional movement and the ecological facets of practices such as dredging, which is vital for transport and coastal conservation. A striking revelation of our study is the transformation of offshore structures in the Gulf into vibrant marine habitats. Emphasizing the intertwined nature of marine infrastructures, we denote oceans as pivotal platforms for impending urban expansion, especially as land resources wane. Our research aspires to validate the role played by oceans as a nexus in the urban–industrial–energy fusion.

Authors: Díaz-Padilla Vidina Tais , Travar Irena , Acosta-Rubio Zamira , Parra-López Eduardo
Published: September 2023

The pandemic changed the strategic business approach of tourist destinations on a global scale. Given this new scenario, there is a need to implement sustainability strategies that are aligned with economic, social, and environmental aspects to continue competing in the international tourism market. Therefore, identifying these strategies, specific to each destination, is a key variable for tourism competitiveness. To help destination managers, this paper aims to measure tourism competitiveness in terms of sustainability. Using the Rasch model, the analysis confirms that the Sustainable Development Goals (SDGs) represent and, thus, measure tourism competitiveness. In addition, the results obtained show that the countries with the highest socioeconomic development are the most competitive tourist destinations, and the most relevant SDGs for tourism competitiveness are related to prosperity and social guarantees.

Authors: De Simone Valentina , Di Pasquale Valentina , Nenni Maria Elena , Miranda Salvatore
Published: September 2023

Production planning and control (PPC), responsible for all the activities that keep production running regularly, plays an essential role in the transition to more sustainable manufacturing systems. PPC decision-making processes need to be driven by sustainable principles even if this makes them more effortful and complex from the strategic to operative level. This study aims to review the scientific literature relating to sustainable PPC. A bibliometric analysis of 437 papers published on the Scopus database was performed to identify the most relevant articles, authors, and journals and to provide the current topic trends and future research themes and gaps. The findings revealed the increasing interest in this topic mainly since 2018. China and the USA are the most productive countries, whereas the Journal of Cleaner Production and Sustainability are the most productive journals. The analysis has also highlighted the ways to address sustainability issues in PPC, e.g., by integrating in scheduling models objectives related to sustainability or by removing barriers to reverse logistics and circular economy at the PPC level. The following topics, instead, deserve further research: attention to the social issues in PPC and the development of decision support systems that will improve companies’ PPC decision-making capabilities in sustainable optics.
Analysis of Control Technology for Large Deformation of a Geological Bedding Bias Tunnel with Weakly Cemented Surrounding Rock
Authors: Ju Jinmao , Liu Honglin , Hu Hongqian , Hang Yinjian , Shan Chengfang , Wang Hongzhi
Published: September 2023

The Baishitou Tunnel of the Dali–Lincang railway project is a weakly cemented surrounding rock tunnel with geological bedding bias. The deformation of the surrounding rock on the side with the greatest stress is nearly 1 m, which seriously affects construction progress and significantly increases construction cost. In order to achieve the goal of safe, efficient, economic, and socially sustainable development in tunnel construction, it is necessary to study the large deformation of weakly cemented surrounding rock in the geological bedding bias tunnel. Engineering technicians first used field measurement methods to monitor the pressure and deformation of surrounding rock and studied the deformation law of surrounding rock pressure and deformation over time. Secondly, numerical simulation methods were used to study the stress distribution law, plastic failure depth, and initial support stress of tunnel-surrounding rock under different support schemes, and they independently designed a yielding anchor bolt with enhanced anchoring, which plays a key role in controlling the deformation of the surrounding rock. The main conclusions are as follows: (1) Through the analysis of the measured pressure data of the initial branch of the section and the displacement monitoring data of the measuring point, it is found that the deformation of the surrounding rock of the weakly cemented tunnel is large and fast. At the same time, the pressure and deformation of the surrounding rock of the tunnel are greatly affected by geological bedding bias. After the excavation of the inverted arch, the pressure and deformation of the surrounding rock at the right arch shoulder of the tunnel are the highest, reaching 0.832 MPa and 0.53 m, which are significantly greater than those on the left arch shoulder. (2) Using the numerical simulation software FLAC3D 5.0 and ANSYS 16.0, a three-dimensional numerical model of the roadway was established to simulate the stress distribution, plastic failure depth, and initial support stress of the tunnel’s surrounding rock under the influence of geological bedding bias. By comparing the support effects of different support schemes, it was concluded that under the support scheme of “I25 arch + yielding anchor bolt”, the surrounding rock failure depth was small, the stress concentration was weak, and the initial support deformation was controllable as a whole. (3) The self-designed yielding anchor bolt has good economic and applicable value, and it has received the expected support effect after field verification. (4) Various special support measures such as advanced grouting anchor rods, casing arches, or temporary cross supports are used to assist in controlling the large deformation of weakly cemented surrounding rock tunnels to a certain extent.

Published: September 2023

Village-owned enterprises are expected to be a forum for village business groups to develop their economic potential. This research aims to understand the reality of village-owned enterprises and their implications for rural businesses. This research focuses on understanding the perspective of other village entities and asking whether these enterprises enhance the rural economy through partnership relationships or become competitors for rural small businesses. This study used a qualitative approach with informants from the village-owned enterprises management and villagers who run small businesses. The results showed that the village-owned enterprises runs a business that resembles the business fields of the villagers. This situation has unconsciously created a sense of competition for both parties. The atmosphere of competition between the two business entities has the potential to hinder the growth of the village’s local economy. This study recommends that village-owned enterprises evaluate their business activities and build a cooperation network for the sustainability of rural businesses. This research contributes to the enrichment and implementation of sustainability by capturing the context of rural business activities in Indonesia.

Published: September 2023

This qualitative study aims to explore the applicability of Twitter as a valuable data source for research on public spaces, with a particular focus on public spaces within the context of Saudi Arabia. The study’s primary objective is to demonstrate Twitter’s efficiency in providing data that would otherwise require substantial time and resources using conventional research methods. Additionally, the study aims to highlight Twitter’s role in monitoring the progress and success of a local urban project. Furthermore, it examines how individuals utilize Twitter to share their experiences and interactions with public spaces, specifically examining content related to a local placemaking initiative in one of Saudi Arabia’s largest cities. To achieve this, a convenience sample of 113 consecutive tweets associated with the local initiative was collected from Twitter. The tweets were then subjected to a thorough thematic analysis framework, yielding three overarching themes: (1) Positive impact and community engagement; (2) Enhancement of the city’s visual landscape; and (3) Community collaboration through volunteer work. These categories provide a comprehensive framework to explore and comprehend the multifaceted dimensions of public space discourse on Twitter. The research presented in this study contributes significantly to the expanding body of knowledge concerning the utilization of social media data for urban research and offers valuable practical implications for planners, designers, and policymakers involved in the development and enhancement of public spaces.

Influence of Deicer on Water Stability of Asphalt Mixture under Freeze–Thaw Cycle
Authors: Guo Mingjun , Kovalskiy Viktor Pavlovich , Nian Tengfei , Li Ping
Published: September 2023

In seasonal frozen soil areas, the repeated freeze–thaw cycle of internal moisture in asphalt mixture in winter and spring will accelerate the peeling of asphalt film and aggravate the water damage of asphalt pavement. It is of great significance to carry out the attenuation law of mechanical properties of asphalt mixture under freeze–thaw cycles to prevent and reduce the economic losses caused by water damage to asphalt pavement. This study will investigate the impact of deicer application on the water stability of asphalt mixtures within the climatic conditions prevalent in Northwest China. Specifically, freeze–thaw cycle tests were administered to two types of dense-graded asphalt mixtures under three distinct deicer solutions and three disparate low-temperature environments. The Marshall water immersion test and freeze–thaw splitting test were employed to evaluate the water stability of asphalt mixtures subject to multiple factors, and the relative importance of each factor was statistically analyzed using the acquired data. Results demonstrated that AC-13 and AC-16 asphalt mixtures (AC is asphalt-concrete, which is asphalt concrete, and 13 or 16 represents the maximum particle size of aggregate (13 mm or 16 mm)), saturated in 15% CH4N2O, 20% NaCl, and 20% CH2CH3OH solutions, underwent a varying number of freezing–thawing cycles (0, 5, 10, 15, 20, 25, and 30) at temperatures of −5 °C, −15 °C, and −25 °C, respectively, displayed a discernible decline in their residual stability MS0 and freeze–thaw splitting tensile strength ratio TSR. This decline was particularly marked when temperatures dropped below the solution’s freezing point. Disregarding the fixed factors of weather variation (different low-temperature environments) and road service duration (number of freezing–thawing cycles), the aggregate grading imposed a more pronounced influence on asphalt mixture water stability than the presence of deicers.
The Initial Impacts of the COVID-19 Pandemic on Regional Economies in Indonesia: Structural Changes and Regional Income Inequality
Authors: Akita Takahiro , Alisjahbana Armida Salsiah
Published: September 2023

The COVID-19 pandemic has exerted an enormous impact on the Indonesian economy. In 2020, the country’s economy contracted by 2.7%. However, the impact has been spatially heterogeneous. Based on provincial GDP across industrial sectors, this study examines how structural changes caused by the pandemic have affected the determinants of inter-provincial inequality in Indonesia by conducting a bi-dimensional inequality decomposition analysis. According to the bi-dimensional decomposition analysis, after the outbreak of COVID-19, the tourism sector reduced its contribution to inter-provincial inequality. On the other hand, the IC and financial services sectors were not affected by the pandemic and raised their contributions. When Indonesia recovers from the pandemic, it is likely that the tourism sector will regain its position as an important determinant of inter-provincial inequality. However, the most important sectors in determining inter-provincial inequality will be the IC, financial, and business services sectors, particularly in the Java–Bali region. With the rapid advancement of IC, financial, and e-business technologies, the roles of these high-inequality sectors are likely to increase unless policies that could facilitate spatial dispersion of these services and activities are implemented.
Spread Is Better: Suitability for Climate Neutrality of Italian Urban Systems
Authors: Bertin Mattia , Fabian Lorenzo
Published: September 2023

In light of the challenges required by the European Green Deal policies concerning the achievement of climate neutrality by 2050, this paper analyses the suitability of different Italian urban systems for energy consumption and CO2 emission reduction. In anthropised territories, there are strong relationships between energy consumption, climate-changing emissions and settlement patterns. Lands considered low could increase their rating because they have far greater environmental, energy and land resources than more pivotal ones. After an Italian-scale overview of the ecosystem capacities, this paper develops a detailed study of three exemplary areas: the northeast, the northwest, and the central-west coast. The analysis uses Burkhard’s matrix for ecosystem values and the energy consumption 2021 report of the National Energy Authority. The first finding is that the northeast region, characterised by spread and rarefied urbanisation, has a peculiar suitability for climate neutrality. In the results, spread territories perform much better than centralised ones. The coexistence of little urban cores, space for vegetation and a widespread water network promotes synergies for enhancing an ecosystem approach to land design.
Bayes Estimation for the Rayleigh–Weibull Distribution Based on Progressive Type-II Censored Samples for Cancer Data in Medicine
Authors: Akdam Neriman
Published: September 2023

The aim of this study is to obtain the Bayes estimators and the maximum likelihood estimators (MLEs) for the unknown parameters of the Rayleigh–Weibull (RW) distribution based on progressive type-II censored samples. The approximate Bayes estimators are calculated using the idea of Lindley, Tierney–Kadane approximations, and also the Markov Chain Monte Carlo (MCMC) method under the squared-error loss function when the Bayes estimators are not handed in explicit forms. In this study, the approximate Bayes estimates are compared with the maximum likelihood estimates in the aspect of the estimated risks (ERs) using Monte Carlo simulation. The asymptotic confidence intervals for the unknown parameters are obtained using the MLEs of parameters. In addition, the coverage probabilities the parametric bootstrap estimates are computed. Real lifetime datasets related to bladder cancer, head and neck cancer, and leukemia are used to illustrate the empirical results belonging to the approximate Bayes estimates, the maximum likelihood estimates, and the parametric bootstrap intervals.
Flavor Symmetry of Hydrogen Atoms Potentially Affecting the Proton Radius Deduced from the Electron-Hydrogen Scattering
Authors: Oks Eugene
Published: September 2023

Precise knowledge of such fundamental quantity as the proton charge radius rp is extremely important both for the quantum chromodynamics (for quark-gluon structure) and for atomic physics (for atomic hydrogen spectroscopy). Yet the ambiguity in measuring rp persists for over a dozen of years by now—from the time when in 2010 the muonic hydrogen spectroscopy experiment yielded rp ≈ 0.84 fm in contrast to the form factor experiment by the Mainz group that produced rp ≈ 0.88 fm. Important was that this difference corresponded to about seven standard deviations and therefore was inexplicable. In the intervening dozen of years, more experiments of various kinds were performed in this regard. Nevertheless, the controversy remains, which is why several different types of new experiments are being prepared for measuring rp. In one of our previous papers, we pointed out the factor that was never taken into account by the corresponding research community: the flavor symmetry of electronic hydrogen atoms, whose existence was confirmed by four kinds of atomic or molecular experiments and also evidenced by two kinds of astrophysical observations. Specifically, in that paper there was discussed the possible presence of the second flavor of muonic hydrogen atoms (in the corresponding experimental gas) and its effect on the shift of the ground state of muonic hydrogen atoms due to the proton finite size. In the present paper we analyze the effect of the flavor symmetry of electronic hydrogen atoms on the corresponding elastic scattering cross-section and on the proton charge radius rp deduced from the cross-section. As an example, we use our analytical results for reconciling two distinct values of rp obtained in different elastic scattering experiments: 0.88 fm and 0.84 fm (which is by about 4.5% smaller than 0.88 fm). We show that if the ratio of the second flavor of hydrogen atoms to the usual hydrogen atoms in the experimental gas would be about 0.3, then the extraction of rp from the corresponding cross-section would yield by about 4.5% smaller value of rp compared to its true value. We also derive the corresponding general formulas that can be used for interpreting the future electronic and muonic experiments.

Microplastics are readily available in the natural environment. Due to the pervasiveness of microplastic pollution, its effects on living organisms necessitate further investigation. The size, time of exposure, and amount of microplastic particles appear to be the most essential factor in determining their toxicological effects, either organismal or sub-organismal. For our research work, we preferred to work on a terrestrial model organism Drosophila melanogaster (Oregon R+). Therefore, in the present study, we characterized 2–100 µm size PET microplastic and confirmed its accumulation in Drosophila, which allowed us to proceed further in our research work. At larger dosages, research on locomotory activities such as climbing, jumping, and crawling indicated a decline in physiological and neuromuscular functions. Our studies also determined retarded development in flies and decreased survival rate in female flies after exposure to the highest concentration of microplastics. These experimental findings provide insight into the possible potential neurotoxic effects of microplastics and their detrimental effects on the development and growth of flies.
Unconventional Mechanisms of Heavy Quark Fragmentation
Authors: Kopeliovich Boris , Nemchik Jan , Potashnikova Irina , Schmidt Ivan
Published: September 2023

Heavy and light quarks produced in high-pT partonic collisions radiate differently. Heavy quarks regenerate their color field, stripped-off in the hard reaction, much faster than the light ones and radiate a significantly smaller fraction of the initial quark energy. This peculiar feature of heavy-quark jets leads to a specific shape of the fragmentation functions observed in e+e− annihilation. Differently from light flavors, the heavy quark fragmentation function strongly peaks at large fractional momentum z, i.e., the produced heavy–light mesons, B or D, carry the main fraction of the jet momentum. This is a clear evidence of the dead-cone effect, and of a short production time of a heavy–light mesons. Contrary to propagation of a small qq¯ dipole, which survives in the medium due to color transparency, a heavy–light Qq¯ dipole promptly expands to a large size. Such a big dipole has no chance to remain intact in a dense medium produced in relativistic heavy ion collisions. On the other hand, a breakup of such a dipole does not affect much the production rate of Qq¯ mesons, differently from the case of light qq¯ meson production.

Published: September 2023

This study combines a traditional chemical characterization with a simultaneous biological evaluation through histological, immunohistochemical, and enzymatic observations to assess the efficiency and sustainability of soil washing on Hg-contaminated sediment in terms of the bioavailability of the contaminant before and after the treatment, as well as the potential drawbacks of the treatment that are not revealed by a simple chemical characterization of treated sediments on its own. Different extracting agents, that is, ethylenedinitrilotetraacetic acid (EDTA), ethylenediaminedisuccinic acid (EDDS), sodium thiosulfate, potassium iodide (KI), and iodine (I2), have been compared in this work to evaluate their efficiency in the removal of Hg from contaminated sediments. Speciation analysis was applied to assess the mobility of Hg from different fractions of aged sediments. Biological evaluation was carried out through the use of large mesocosms and Mytilus galloprovincialis as biological sentinels. Results from bench scale tests have shown Hg removal of up to 93% by means of the multi-step KI/I2 washing process of the sediment. Results from histological, immunohistochemical, and enzymatic analysis have shown significant differences in the degree of alteration of biological tissues and their functional integrity between organisms in contact with contaminated and restored sediments. The reduction in 5-HT3R immunopositivity in the mesocosm with treated sediments suggests a tendency for mussels to recover a healthy condition. This result was also confirmed by the measurement of the enzymatic activity of AChE in mussel gills, which was significantly reduced in organisms from the mesocosm with polluted sediments compared with those from the one with restored sediments. The proposed approach could help stakeholders all over the world select, at an early stage, the most efficient cleaning action from a more holistic perspective, including not only pollutant concentration and economic reduction but also a direct assessment of the ultimate impact of the selected process on the biological system.

Authors: Li Man , Li Shanshan , Liu Huancai , Zhang Junjie
Published: September 2023

Water yield and purification are important aspects of water ecosystem services, and achieving a balanced development of the two is necessary for the development of aquatic ecosystems. Using the InVEST model, the spatiotemporal variations of regional water yield and purification services in Shanxi, China, from 2000 to 2020 were analyzed. Three future scenarios (natural development, urban development, and ecological protection) were assessed for 2030 using the PLUS model. The results showed that in 2000–2020, the water yield of Shanxi Province in terms of space was generally low in the middle and northwest and high in the southeast, and it was affected by land-use change and climatic change. From 2000 to 2020, the water yield of Shanxi Province changed by 78.8 mm. In 2030, water yield will be highest under the urban development scenario (380.53 mm) and lowest in the ecological protection scenario (368.22 mm). Moreover, the water quality purification capacity improved, with nitrogen loading high in the center and low in the east and west. Due to the implementation of environmental protection policies and the improvement of the technical level, the nitrogen load was the highest in 2000 (0.97 kg/hm2) and lowest in 2015 (0.94 kg/hm2). By 2030, because of the high nitrogen loadings of cultivation and construction land and low nitrogen loadings of forests and grasslands, the nitrogen load was lowest under the scenario of urban development (0.94 kg/hm2) and highest under ecological protection (0.85 kg/hm2).

Published: September 2023

Systematic, quantitative evidence on education system coherence is limited. Prior research has indicated alignment of instructional components, such as curriculum standards, assessments, and teachers’ instruction, is important for children’s learning. This study uses the Surveys of Enacted Curriculum methodology to investigate alignment of instructional components in Nigeria's primary education system. The study analyzes curriculum standards, national exams, and classroom instructional content for mathematics and English language across all six primary-level grades. We find that key foundational mathematics and English language skills are covered by all three components, with some notable omissions on the end-of-cycle English language exams. All three components give high emphasis to the low cognitive demand processes of ‘memorize’ ‘perform’, and ‘demonstrate’, and give very low emphasis to the more demanding cognitive processes of ‘analyze’ and ‘apply to non-routine situations’. Both the curriculum standards and classroom instruction depict a slow pace of content progression across grades, manifested through broad but shallow content coverage. The high alignment suggests the potential for a well-functioning education system, however, low student performance in mathematics and English language exams suggest otherwise. The findings suggest the Nigerian primary education system may be operating in a low-achieving equilibrium in which the system is aligned for low levels of cognitive demand and student mastery.
El Proceso de Civilización y la Modernidad Eurocéntrica en Norbert Elías y Aníbal Quijano
Authors: Lazo López Luis Miguel
Published: September 2023

The contributions of Norbert Elías and Aníbal Quijano are fully valid in current social theory. In the specific case of Latin American societies, cultural studies, postcolonial and decolonial subalterns, the epistemologies of the South, Eurocentrism and the critique of modernity, can be reviewed in light of their postulates. Thus, this text explains the theoretical relationship that exists between the Civilization Process and Eurocentric Modernity, categories proposed by Elías (1988) and Quijano (2000) respectively. The central thesis of the essay is that civilization and modernity in the Latin American context are the two sides of the same coin, and have been historically intertwined with an epistemic purpose, that is, having the power of knowledge.

El gold estándar en los países desarrollados es la reconstrucción mamaria inmediata, y actualmente existen pocas contraindicaciones absolutas para realizar alguna técnica de reconstrucción. Este artículo se describen las opciones reconstructivas (colgajos e implantes), tiempos de reconstrucción, ventajas y desventajas de ambas técnicas, potenciales complicaciones, y se propone un algoritmo de tratamiento. La elección de la técnica de reconstrucción debería ser decidida entre la paciente y su cirujano/a, considerando características físicas, factores relacionados con la enfermedad y tratamiento oncológico, y preferencias de las pacientes.

In this study, an all-dielectric metasurface with an F-shaped chiral structure in the terahertz region has been proposed. The coupling between the electric and magnetic dipole modes supported by the metasurface can be adjusted by varying the structural parameters. In the parameter space composed of l
l and s, any closed path around exceptional point in the circular polarization conversion channel t

O Lugar como mediação na abordagem de conceitos e temas da Geografia Escolar
Authors: Santos Rodrigues Caio , Costa Junior Ronaldo Santos
Published: September 2023

Este artigo tem como objetivo apresentar uma discussão do conceito de lugar na perspectiva da Geografia humanista e da Geografia escolar, vinculando às dimensões fenomenológicas da realidade do estudante e à educação geográfica, na possiblidade de uma leitura dos espaços vividos de forma próxima à dinâmica cotidiana dos estudantes, pois, tal relação está fundamentada nos princípios de uma abordagem que valoriza as geografias vividas no espaço-tempo em que foram experimentadas. Apoiado nessa corrente, entende-se que as vivências e experiências – produto da geograficidade – são elementos constitutivos do espaço mais imediato de cada sujeito, dessa forma, esse trabalho propõem uma articulação dessa dimensão no processo de ensino/aprendizagem dos conhecimentos geográficos. A compressão de conceitos/categorias se configura como um desafio para o educando. Partindo dessa premissa, defende-se uma abordagem que pode ter como ponto de partida a própria existência do sujeito no mundo. O itinerário percorrido na produção deste texto seu deu a partir e exclusivamente de pesquisa bibliográfica. Sendo assim, alguns autores e autoras nortearam as reflexões tecidas: Relph (2014), Tuan (2013), Marandola (2021), Marandola e Oliveira (2019), Massey (2008), Callai (2010). Nesse aspecto, esse caminho possibilitou diálogos em torno de temáticas inerentes a geograficidade do estudante, contemplando dimensões que emergem do lugar de vivência.
Avaliação de medidas estruturais de combate a riscos de inundações urbanas no rio Itapicuru-Mirim, Jacobina, Bahia

Este trabalho objetiva discutir as principais medidas estruturais de combate a riscos de inundação do rio Itapicuru-mirim, localizado na cidade de Jacobina, Bahia. A metodologia adotada no trabalho envolveu pesquisa bibliográfica, especialmente, para a discussão de fontes secundárias. Além disso, utilizou-se a pesquisa de campo para observações, registros fotográficos e anotações. Os resultados apontam intervenções hidrológicas estruturais importantes após a década de 1940, com canalizações nas partes sudoeste, central e leste da cidade de Jacobina. Foram registradas três inundações de destaque no século XX e duas neste século, apontando que as políticas públicas foram insuficientes para extinguir eventos de origem hidrológica, porém induzidas por contradições territoriais. Afirma-se que o ordenamento da cidade de Jacobina não contempla a gestão e planejamento adequados, subsidiando segregações e desigualdades sócio-espaciais.
