Authors: Zhang Chengkai , Zhang Yanjun , Li Yu , Li Shan
Published: May 2023

Based on Chinese provincial data from 2013 to 2020, this research constructed a fintech index and a digital index and analyzed the temporal and spatial coupling coordination status and driving factors of the two using a coupled coordination model. The results of the study were as follows. (1) In general, the comprehensive index of fintech and digital villages increased year by year in the time sequence and fell into fintech-dominated coupling. The divergence in space was significant, showing an overall decreasing trend from the eastern coastal areas to the central areas and western areas. (2) In terms of sequential characteristics, the coupling coordination between fintech and digital villages shifted into the stage of primary coordination, which was phased and rising and continued to grow during the examination period. (3) In terms of spatial characteristics, the degree of coupling coordination between fintech and digital villages was different and agglomerative, with a trend of “strong in the east, mediocre in the middle and poor in the west”; seven provinces and cities entered the intermediate coordination stage. (4) In terms of drivers, the levels of economic development, regional industrial structure, regional population density, and digital infrastructure had a positive influence on coupling coordination. (5) Conditional convergence existed in eastern, central and western China from the convergence test; also, the speed was faster than absolute convergence.

Authors: Wang Min , Ji Meng , Wu Xiaofen , Deng Kexin , Jing Xiaodong
Published: May 2023

The improvement of port cluster eco-efficiency is of great significance to constructing a world-class shipping hub and the high-quality development of regional economy. This study adopts the Super-EBM (Super-efficiency Epsilon-Based Measure) model to evaluate the eco-efficiency of the Yangtze River Delta port cluster in China, and the GML (Global Malmquist-Luenberger) index, spatial hot spot analysis, gravity center migration model, and the Theil index are combined to reveal the spatial-temporal evolution. The results show that the average eco-efficiency of the Yangtze River Delta port cluster is 0.686, with 55.6% of the ports being below the average, which is directly related to the low scale efficiency. Mainly driven by technical efficiency improvement, the overall eco-efficiency has a growth rate of 8.7% from 2010 to 2019. Moreover, considerable spatial divergence has formed in the port cluster, and the eco-efficiency gravity center has always been in the south of Jiangsu. The overall eco-efficiency gap has widened by 19.92%, and the gap within the region, particularly within Zhejiang, is the major source. To improve the overall eco-efficiency of the port cluster, policymakers should strengthen the technological spillover of ecologically efficient ports in clean production and mechanism reform, while optimizing the resource consolidation system of ports with relatively low eco-efficiency.
Creative Hubs and Intercultural Dialogue—Towards a New Socio-Economic Narrative
Authors: Komorowski Marlen , Fodor Máté Miklós , Pepper Sara , Lewis Justin
Published: May 2023

This paper argues that creative hubs are enablers and curators of intercultural dialogue. Building upon an internationally funded project bringing together creative hubs from Turkey, Greece, Serbia and the UK, research was carried out through a survey analysis across these four countries with 98 creative hubs and four workshops in co-working spaces (involving 29 creative hub experts). Based on the data collected, this paper suggests a new framework for understanding intercultural dialogue in creative hubs through their spatial and cultural attributes, as well as through their levels of activity. The findings support the argument for a shift from an economic to a socio-economic narrative around creative hubs.
Ecological Health Assessment of an Urban River: The Case Study of Zhengzhou City, China
Authors: Li Jie , Huang Lintong , Zhu Kai
Published: May 2023

Urban river ecological health assessment is an effective means to manage urban rivers, and combining principles of landscape ecology can provide new help for the ecological restoration of urban rivers and improving their ecosystem service value. From the perspective of important functions of ecosystems, based on typical sample site investigations of different river sections, questionnaire surveys, and remote sensing technology, a fuzzy comprehensive evaluation model based on the factor analysis method was used to construct an indicator system that can quantitatively reflect the ecological health of urban rivers. This comprehensive evaluation index system includes five major functions: social function, habitat and corridor function, water ecological function, water landscape function, and spatial enclosure function. The study identified key areas, key rivers, key river sections, and main indicator projects for the ecological restoration of the urban river landscape corridors in Zhengzhou. The study results also showed that the urban river landscape corridors in Zhengzhou have prominent problems in social function, water ecological function, and habitat and corridor function, and 62.1% of the river sections are currently in a sub-healthy state. The flood control function, eutrophication of water body, naturalization rate of revetment, and five other indicators in the old city district are significantly lower than those in the new city district, and the old city district should be the focus of the ecological restoration of urban river corridors. From the evaluation of the ecological health status of typical river sections, the Jinshui River and Xionger River have a larger number of river sections that urgently need restoration. This study provides a reference for the ecological restoration of urban rivers in Zhengzhou, a rapidly urbanizing region, and has reference significance for the construction of water landscapes in small and medium-sized cities with low levels of urbanization.
Effect and Mechanism of Environmental Decentralization on Pollution Emission from Pig Farming—Evidence from China
Authors: Shao Haiying , Li Bowen , Jiang Yanjun
Published: May 2023

Pollutants produced by pig breeding are among the important pollutions. It is necessary to explore the factors influencing the emission intensity of pollutants from pig breeding and find ways to decrease them. Using the provincial panel data of China from 2001 to 2017, this paper analyzed the mechanism impact of environmental decentralization on pollution emission from pig farming. The results showed that environmental decentralization could significantly reduce the emission intensity of pollutants from pig farming. Decentralization of environmental monitoring had a certain effect on reducing such emission intensity, while decentralization of environmental administration has not played this role. In addition, the scale of pig farming can effectively strengthen the effect of environmental decentralization on pollution reduction in pig farming. From the perspective of regional heterogeneity, environmental decentralization can reduce such emission intensity in restricted development areas, potential growth areas, and moderate development areas. Also, decentralization of environmental monitoring can also, obviously, reduce pollutant emissions in potential growth areas. The research results have reference value for determining the reasonable level of environmental decentralization between regions and improving environmental regulation policies.
A Study of Multidimensional and Persistent Poverty among Migrant Workers: Evidence from China’s CFPS 2014–2020
Authors: Chen Yiyan , Tang Zhaoyun
Published: May 2023

Poverty is a critical social problem in numerous countries. It is a result of many aspects and has been addressed worldwide for a long time. In this study, we construct the multidimensional poverty index (MPI) for migrant workers in China based on Amartya Sen’s capabilities approach. Using the Chinese Family Panel Studies (CFPS) data during 2014–2020 and the Alkire–Foster methodology, our study examines the multidimensional poverty of migrant workers using static to dynamic analyses. The results show the following: (1) The multidimensional poverty of migrant workers shows a general decreasing trend over time. (2) Over one third of migrant workers are in severe multidimensional poverty. (3) The in-work poverty of migrant workers is serious, which is reflected in the indicators of employment security, housing provident fund, labor contract, and labor union. (4) Approximately 30% of migrant workers’ multidimensional poverty is persistent. It is difficult for them to rid themselves of persistent poverty by their own effort. This study suggests that the government should pay more attention to poverty reduction and capability improvement for migrant workers.
A Case Study on Hierarchical Linear Models Applied to the UN’s Sustainable Development Goals (SDGs): A Perspective Using the World and Brazil’s Data
Authors: Lemes Murilo , Belfiore Patrícia , Fávero Luiz Paulo
Published: May 2023

This study analyzed the statistical relation between the Sustainable Development Goals and their relative indicators for the UN’s 2030 Agenda through the implementation of a two-level linear hierarchical model (HLM2) using STATA/SE 16 statistical software. The objective of this model was to address priorities by saying how much and where each country should invest so that they can achieve these goals by the end of the decade. Intrinsically, it was checked whether the indicators listed by the UN are statistically capable of describing the expected output. After analyzing the results, SDGs 8, 9 and 7 were, respectively, identified as priorities. The HLM2 also pointed out that economic growth is the most important variable amongst all considered. Finally, it was concluded that a generic answer does not serve to respond to the complexities worldwide, and therefore, it would be more appropriate to direct actions on a case-by-case basis.
Study on the Factors Influencing and Mechanisms Shaping the Institutional Resilience of Mega Railway Construction Projects
Authors: Zhao Xi , Liu Yuming , Jiang Wenchao , Wei Dongri
Published: May 2023

With mega railway construction projects (MRCPs) facing various natural disasters and extremely difficult engineering construction tasks, there is an urgent need to improve the resilience management capability of engineering construction to cope with complex and changing internal and external risks. As a key element of the construction management system, the level of institutional resilience directly determines the adaptability of the construction system in the face of crisis. However, the research on the influencing factors and the formation mechanism of institutional resilience is slightly insufficient. Therefore, this paper defines the connotation of institutional resilience in MRCPs on the basis of existing research. Secondly, it codes authoritative journals and expert interview reports related to MRCPs in China by applying a rooting theory. Finally, the paper analyses the formation mechanism of institutional resilience based on an Interpretative Structural Modeling and proposes strategies to enhance it. The results show that the institutional environment is the fundamental influencing factor, institutional implementation, institutional supervision, institutional guarantee and institutional feedback are the direct influencing factors, and institutional stakeholders and institutional design are indirect influencing factors. The mechanism of interaction between the institution and the institutional environment, the mechanism of interaction between the institution and the institutional stakeholders, the mechanism of generation of institutional rules and the mechanism of operation of institutional rules work together to generate institutional resilience. This paper, as an exploratory study on institutional resilience in the field of engineering management, has sorted out the ideas for the subsequent research on institutional resilience in this field and provided the directions for project managers of MRCPs to improve their institutional systems.
Driving New Venture Sustainability: A Study Based on Configuration Theory and Resource Orchestration Theory
Authors: Song Ruiqi , Xiang Lingduan
Published: May 2023

New ventures often face the challenge of resource scarcity, and how to overcome the resource constraint problem and improve new venture sustainability has been a long-standing concern of scholars and practitioners. Most existing studies have explored the impact on the financial performance of new ventures of a single factor, and few studies have focused on the impact of the configuration effect of multiple factors on new venture sustainability. In this paper, based on the configuration theory and resource orchestration theory, we use fuzzy-set qualitative comparative analysis (fsQCA) with a sample of 189 entrepreneurs to explore the mechanisms driving the configuration effects of multiple factors of entrepreneurial decision-making logic, resource bundling, and environmental uncertainty on new venture sustainability. The empirical results show that the paths to achieve high new venture sustainability are diverse and equivalent, and effectuation is a core antecedent condition in all paths. There are four conditional configurations of the drivers of high sustainability in new ventures, including dual-logic resource integration, market-driven resource integration, means–resource innovation in emerging markets, and resource-rich or resource-creating integration under dual logic.

Published: May 2023

Habitat fragmentation seriously threatens urban biodiversity conservation and ecosystem integrity. Constructing an ecological network and improving the connection level between habitat patches can effectively alleviate the general ecological environmental problems of rapid urban development. In this paper, three focal animal species were selected in the central urban area of Yichang City in China. Based on the habitat quality assessment results of the InVEST model, the ecological network of the three focal species was designed by combining morphological spatial pattern analysis and least-cost path models, and a multi-species comprehensive ecological network of the study area was designed. The consensus identified 31 ecological sources, 64 ecological corridors and 151 ecological nodes. The results can provide support for biodiversity conservation and green space planning in the study area, and also provide a reference for the construction and optimization of ecological networks for biodiversity conservation in urbanized areas.

Authors: Tennakoon Hemamali , Hansen Jared M. , Saridakis George , Samaratunga Mahesha , Hansen Joseph W.
Published: May 2023

Online and distance learning classes have been touted for the last several years as an innovation in higher education that should help improve the entrepreneurial growth mindset of students. However, the reported negative online learning experience of many college students worldwide during the COVID-19 epidemic has shown that many opportunities remain to improve the sustainable development and growth of online visual instruction practices. In this study, we outline and investigate a set of hypotheses related to the perceived usefulness and perceived ease of use (from TAM) of online video instruction in higher education courses during the pandemic. We employ grounded theory using autoethnographic case studies as a data source. We found that (a) synchronous broadcast lectures improve participant attitude (H1) and motivation (H2) toward online instruction, (b) prerecorded video instruction increases participant perceived “ease of use” (H3) and perceived behavioral control (H4) of online instruction, but (c) indicators of recorded dates on pre-recorded video instruction decreases participant perceived “usefulness” (H5) and “certainty” (H6) of online instruction. We enrich the insights of popular motivation models for organizations and the higher education industry by outlining a set of emotional elements originating in neuroscience leadership research (SCARF) that might either amplify or diminish the perceived the ease of use and perceived usefulness to technology usage relationships when participations engage in online learning situations.

Authors: Demko-Rihter Jelena , Sekerez Vojislav , Spasić Dejan , Conić Nevena
Published: May 2023

Prices applied to internal transactions between the business segments or divisions of a company in transactions between related entities within a group (transfer pricing) can have a significant impact on a company’s competitive advantage. Transfer pricing policy influences the profits of operating segments, resource allocation and the need for segment reporting. The two main approaches to transfer pricing are the tax and managerial approaches. The aim of this research was to test whether multidivisional companies operating in Serbia give more importance to the tax or the managerial aspect of transfer pricing policy. Another research aim was to determine whether segment reporting is more developed in companies in Serbia that have the legal obligation to prepare consolidated financial statements. Both research hypotheses were confirmed using the questionnaire method on a final sample of 52 large and medium-sized companies (out of 1912 large and medium-sized companies operating in Serbia). First, our findings show that tax compliance is more dominant in transfer pricing than the managerial perspective in the Serbian companies analyzed. Second, we found that mandatory consolidated financial reporting and related segment reporting can influence the managerial approach to transfer pricing in Serbian multidivisional companies and groups. Other factors (production orientation of companies, developed responsibility accounting and managers’ bonuses, for example) also encourage this approach.

Introduction: Remdesivir (REM) and monoclonal antibodies (mAbs) could alleviate severe COVID-19 in at-risk outpatients. However, data on their use in hospitalized patients, particularly in elderly or immunocompromised hosts, are lacking. Methods: All consecutive patients hospitalized with COVID-19 at our unit from 1 July 2021 to 15 March 2022 were retrospectively enrolled. The primary outcome was the progression to severe COVID-19 (P/F < 200). Descriptive statistics, a Cox univariate–multivariate model, and an inverse probability treatment-weighted (IPTW) analysis were performed. Results: Overall, 331 subjects were included; their median (q1–q3) age was 71 (51–80) years, and they were males in 52% of the cases. Of them, 78 (23%) developed severe COVID-19. All-cause in-hospital mortality was 14%; it was higher in those with disease progression (36% vs. 7%, p < 0.001). REM and mAbs resulted in a 7% (95%CI = 3–11%) and 14% (95%CI = 3–25%) reduction in the risk of severe COVID-19, respectively, after adjusting the analysis with the IPTW. In addition, by evaluating only immunocompromised hosts, the combination of REM and mAbs was associated with a significantly lower incidence of severe COVID-19 (aHR = 0.06, 95%CI = 0.02–0.77) when compared with monotherapy. Conclusions: REM and mAbs may reduce the risk of COVID-19 progression in hospitalized patients. Importantly, in immunocompromised hosts, the combination of mAbs and REM may be beneficial.

Published: May 2023

Serum bicarbonate deficiency is a disorder frequently found in human patients with acute (AKI) and chronic (CKD) kidney disease, due to abnormalities in kidney generation and reabsorption of bicarbonate. Although alkali supplementation is usually performed in both humans and veterinary CKD patients, data regarding the frequency of bicarbonate disorders in AKI and CKD dogs are scarce. The aim of the present study is to assess the frequency and the severity of bicarbonate deficiency of dogs affected by AKI, acute chronic kidney disease (ACKD), and CKD, and to investigate its possible association with the IRIS grade/stage as well as with disorders of calcium phosphate metabolism. A retrospective evaluation of the serum biochemical panels of all dogs with diagnoses of AKI, ACKD, and CKD referred to the nephrology and urology service of the Veterinary Teaching Hospital of the University of Pisa, between January 2014 and January 2022, was performed. Bicarbonate deficiency was defined as serum bicarbonate < 22 mmol/L and classified as moderate (between 18 and 22 mmol/L) or severe (<18 mmol/L). Serum bicarbonate deficiency was found in 397/521 dogs (76%), of which 142/397 (36%) showed moderate deficiency, and 255/397 (64%) severe deficiency. Dogs with AKI and ACKD showed a significantly higher frequency of bicarbonate deficiency (p = 0.004) and severe forms compared to CKD dogs (p = 0.02). In AKI and ACKD dogs, a negative linear correlation was found between serum bicarbonate and serum creatinine, urea, and phosphate. The frequency of bicarbonate deficiency was higher in the later stages of the disease in both AKI (p = 0.01), ACKD (p = 0.0003), and CKD dogs (p = 0.009). Dogs with serum CaxP ≥ 70 mg2/dL2 showed a higher frequency of bicarbonate deficiency (p = 0.01) and showed severe forms (p = 0.01) compared to dogs with CaxP < 70 mg2/dL2. Serum bicarbonate deficiency seems to be a very frequent disorder in both AKI, ACKD, and CKD dogs, with an increasing frequency and severity in more advanced stages of kidney disease. The higher frequency and severity of bicarbonate deficiency in AKI and ACKD may be caused by a more severe and sudden loss of kidney function, or extra-renal factors. Finally, the association between frequency and severity of bicarbonate deficiency and abnormal CaxP may suggest a potential connection between metabolic acidosis and bone mineral disorders.

Published: May 2023

Given increasingly prominent environmental issues, there is a pressing need to satisfy more stringent emission standards for wastewater treatment plants (WWTP) while concurrently prioritizing energy conservation; a new up-flow layered nitrogen removal filter was constructed on a laboratory scale using gravel (for the bottom and top layers) and embedded bio-organic carriers (for the middle layer) containing microorganisms as fillers to treat the secondary effluent by introducing a portion of raw water. This study investigated the nitrogen removal effectiveness and transfer pathways of synthetic wastewater at varying mixing ratios, promoted the enrichment of Anammox Bacteria (AnAOB) by embedding microorganisms, and analyzed the microbial community structure using high-throughput sequencing techniques. The findings showed that the highest total nitrogen (TN) removal efficiency was achieved with chemical oxygen demand (COD), ammonia (NH4+-N), and nitrate (NO3−-N) contents in the mixture at 77, 10, and 8 mg·L−1, respectively, with an average efficiency of 89.42%. NO3−-N was mostly removed through denitrification (heterotrophic), while NH4+-N was eliminated by partial nitrification (PN) and anaerobic ammonium oxidation (Anammox, autotrophic). According to high-throughput sequencing results, denitrifying bacteria such as Thauera (1.30–6.96%), Flavobacterium (0.18–0.40%), and Parcubacteria (0.14–0.32%) were present in all the filter layers, and Anammox bacteria such as Candidatus_Kuenenia were predominant in the middle layer at a 0.88% abundance, with the aid of organic carriers.

Mt. Munkhkhairkhan is the most crucial region for understanding climate and glaciation changes in Mongolia. This study investigated the relationship between glacial area changes and the climate elements of Mt. Munkhkhairkhan in the Mongolian-Altai Mountains using a remote sensing approach, in-situ observations, the Mann–Kendall (MK) test, Innovative Trend Analysis Method (ITAM), Sen’s slope estimator test, and statistical analysis. The study results showed that for the last 30 years, the annual average air temperature of Mt. Munkhkhairkhan has been slightly increasing. Total annual precipitation (mainly snow) in the mountain area decreased from 1990 to 2000, but since 2000, a significant increase in precipitation levels has appeared. For the last 30 years, the glacial area has decreased by 32% to 11.7 km2. Multiple regression results showed a strong correlation between Temperature, Precipitation, and Glaciers (Multiple R = 0.69, R2 = 0.48). Ruther indicated that Temperature (t = −2.332, p = 0.036) and Precipitation (t = −3.212, p = 0.007) were significant predictors in the model. Air temperature and precipitation explained 48 percent of the change in the glacier area, and R = 0.69 is a strong correlation. The glaciers and snow area in the study area have changed due to climate warming and precipitation changes and are located in arid and semi-arid regions of Central Asia. This study of Mt. Munkhairkhan shows that climate change significantly impacts glaciers and snow.

The cultivation of the Mediterranean mussel, Mytilus galloprovincialis Lamarck, 1819, has been tested in an innovative Integrated Multitrophic Aquaculture system (IMTA) in the Mar Grande of Taranto, as part of the EU-funded Remedialife project. This farming method could solve several problems including the low growth rate in mesotrophic environments while reducing the environmental impact of fish mariculture. Three productive cycles have been carried out. The first (2018–2019, traditional experiment) was conducted in three long lines around six cages of the fish farm in order to evaluate total mussel production under the innovative IMTA system and quality for human consumption by analyzing the concentration of culturable heterotrophic bacteria, total and fecal coliforms, Escherichia coli and Salmonella spp. in mussel tissues. In addition, 17 polycyclic aromatic hydrocarbons (PAHs), including 16 EPA priority compounds and seven polychlorinated biphenyls (PCBs), which are indicators of PCB contamination in the environment, were analyzed using gas chromatography in conjunction with a mass spectrometer. The second cycle (2020–2021, horizontal distance experiment) aimed to test the influence of fish cages on mussel growth by placing mussels near and far from the fish cages. The third cycle (2021–2022, vertical distance experiment) aimed to overcome the phenomenon of “heat waves” that can occur in the Mar Grande of Taranto during summer by testing the growth performance of mussels at two different depths (1 and 12 m). The following parameters were measured: Shell Length, L (mm); Shell Dry Weight, SDW (g); Flesh Dry Weight, FDW (g); Condition Index, IC = FDW/SDW. The results showed that the best growth performance was obtained near the fish cages and at a depth of 12 m. Moreover, the indicators of microbial contamination and concentrations of chemical compounds analyzed in mussel tissues cultured under the innovative IMTA system were in compliance with the reference values of European regulations.
Machine Learning Framework with Feature Importance Interpretation for Discharge Estimation: A Case Study in Huitanggou Sluice Hydrological Station, China
Authors: He Sheng , Niu Geng , Sang Xuefeng , Sun Xiaozhong , Yin Junxian , Chen Heting
Published: May 2023

Accurate and reliable discharge estimation plays an important role in water resource management as well as downstream applications such as ecosystem conservation and flood control. Recently, data-driven machine learning (ML) techniques showed seemingly insurmountable performance in runoff forecasting and other geophysical domains, but they still need to be improved in terms of reliability and interpretability. In this study, focusing on discharge estimation and management, we developed an ML-based framework and applied it to the Huitanggou sluice hydrological station in Anhui Province, China. The framework contains two ML algorithms, the ensemble learning random forest (ELRF) and the ensemble learning gradient boosting decision tree (ELGBDT). The SHapley Additive exPlanation (SHAP) was introduced into our framework to interpret the impact of the model features. In our framework, the correlation analysis of the dataset can provide feature information for modeling, and the quartile method was utilized to solve the outlier problem of the dataset. The Bayesian optimization algorithm was adopted to optimize the hyperparameters of the ensemble ML models. The ensemble ML models are further compared with the traditional stage–discharge rating curve (SDRC) method and the single ML model. The results show that the estimation performance of the ensemble ML models is superior to that of the SDRC and the single ML model. In addition, an analysis of the discharge estimation without considering the flow state was performed. This analysis reveals that the ensemble ML models have strong adaptability. The ensemble ML models accurately estimate the discharge, with a coefficient of determination of 0.963, a root mean squared error of 31.268, and a coefficient of correlation of 0.984. Our framework can prove helpful to improve the efficiency of short-term hydrological estimation and simultaneously provide the interpretation of the impact of the hydrological features on estimation results.

The purpose of this study is to identify the leading causes of slope instability along a local highway in Anhui, People’s Republic of China. As part of the east expansion project, the mountain range will be excavated to create a two-way, nearly 30 m wide highway. The site’s topography consists of a hill with palm-shaped faces carved from limestone running along its sides. The geological characteristics and slope stability of the research area highlight the possibility of slope failure along both sides of the roadway. Slope stability analysis was performed in order to determine the failure mechanism and create a stable slope. Initial slope characterization and shear properties of the rock were determined by means of fieldwork and laboratory analysis. By causing wedging failure and toppling collapse, the bedding joints and discontinuity orientations increase instability, as determined by a kinematic analysis performed with DIP.6 software. The Limit Equilibrium Method (LEM) of analysis is presented in the software Slide 6.020 to illustrate the instability of the slope. The unstable condition of the slopes was determined using empirical methods that were validated and enhanced by limit equilibrium analysis.
Effects of Salinity, pH, and Cu(II) on the Adsorption Behaviors of Tetracycline onto Polyvinyl Chloride Microplastics: A Site Energy Distribution Analysis
Authors: Liang Yifan , Ying Chuhan , Zhu Jianyu , Zhou Qian , Sun Kuan , Tian Yajun , Li Jun
Published: May 2023

Microplastics (MPs), as vectors for various pollutants in the environment, have been arousing public concern in recent years. The extensive use of antibiotics has led to their frequent detection in water environments, where they inevitably coexist with MPs and are actively adsorbed onto MPs’ surfaces. However, the information on the influence of the main environmental factors on the sorption behavior of MPs is not fully understood, and especially, information about the effect mechanism is limited. This study aims to comprehensively assess the main factors and mechanisms that affect antibiotic sorption onto microplastics. The results indicated that the adsorption of tetracycline (TC) onto PVC MPs fits the pseudo-second-order model well. The adsorption of TC onto PVC MPs decreased with increasing salinity and pH. With the help of SED analysis, the decrease at high salinity was attributed to the decreased quantities of the most distributed energy sites in high-salinity systems compared to freshwater. Additionally, the decreased adsorption capacity of TC onto MPs at high pH mainly resulted from the electrostatic repulsion between MPs and TC2−. The coexisting Cu2+ and TC could improve the affinity between PVC MPs and TC via “MPs-TC-Cu2+” and “MPs-Cu2+-TC” bridges, boosting the capacity of PVC MPs to adsorb TC. This study provides comprehensive insights into the influence and mechanism of the main factors on the environmental behaviors of the coexistence of MPs with antibiotics, which is of great importance for evaluating and controlling their risks.

Published: May 2023

The aim of this study was to investigate the long-term changes in the coastal stretch of the Lido barrier island, a 12 km sandy coast bordering the Lagoon of Venice, and to assess the impacts of human interventions in the system. Coastal modifications were examined in a GIS environment through the analysis of aerial photographs covering the period 1955–2019. To achieve our goal, the study area was divided into three cells (i.e., from north to south, A, B, and C), and the rates of shoreline change were calculated over five subsequent periods (i.e., 1955–1978, 1978–1987, 1987–1996, 1996–2006, and 2006–2019). The results mainly showed a positive trend in the long-term (cell A avg. 2.0 m/year; cell C avg. 1.2 m/year) and moderate erosion (cell A and C avg. 0.9 m/year) in the periods 1996–2006 and 2006–2019, probably due to an increase in the frequency of storm surges. However, major effects on beach erosion and progradation were produced by human interventions. In particular, positive impacts were derived from the shore-normal engineering structures intercepting longshore currents, whereas negative effects were from works functional to the realisation of the MoSE system at the Lido and Malamocco inlets, which reduced the amount of available sediment, thus contributing to the worsening conditions of cells A and C. In view of the expected sea-level rise, this area merits higher consideration for correct spatial planning in the framework of integrated coastal zone management. We suggest that a monitoring program of shoreline evolution must be set up to better manage its future development.

Published: May 2023

The selection of pumps as turbines (PATs) for their respective use in energy optimisation systems is a complicated task, because manufacturers do not provide the characteristic curves. For this reason, some research has been carried out to predict them with computational fluid dynamics (CFD) and mathematical models. The purpose of this study is to validate these two prediction methodologies of flow (Q) vs. head (H) curves through numerical modelling using the computational package OpenFOAM, together with a comparison with the experimental data obtained from a PAT for the case in which the nominal rotation speed of the machine varies. Depending on the configuration and working conditions of the PAT, the simulation performed with OpenFOAM was validated by calibrating it with the nominal curve of the pump and with another simulation performed with CFD workbench SOLIDWORKS FloEFD. Subsequently, the second methodology related to the analyses and mathematical models proposed to predict the Q vs. H curves were also validated with new models in OpenFOAM and the experimental data. The results show that these prediction methods are effective when a machine’s operating point is close to the BEP (best efficient point). The absolute error ranges obtained with these two prediction methodologies for rotation speeds of 880 rpm, 1020 rpm, 1200 rpm, and 1500 rpm are between 5 and 24%, 2 and 17%, 0 and 12%, and 1 and 24%, respectively.

The study of issues related to theories, concepts and paradigms is certainly important for both science and practice in absolutely any field. In the previous article, we analyzed the fundamental questions in the field of theories, concepts and paradigms of accounting and reporting. In this article, we continue our research in this area. We used the following research methods: analysis and synthesis, comparison, grouping method, analogy method, logical approach, historical approach, systematic approach. As a result of the research, this article, in particular, gives its own definition of the theory, presents the author’s view on the correlation of theories, concepts and paradigms, including accounting and reporting, analyzes the theories, concepts and paradigms of accounting and reporting, described by modern Russian and foreign scientists, present author’s vision of the reasons for the existing significant discrepancies on these issues in various sources. In future works, we will continue research in this area.

As terapias complementares para o alívio da dor estão cada vez mais frequentes nas maternidades, sendo que o desenvolvimento de tais práticas também consiste em uma das atribuições dos serviços hospitalares de referência à Atenção à Gestação de Alto Risco. Neste sentido, o presente estudo buscou avaliar o uso de práticas humanizadas em uma instituição de referência à gestação de alto risco em Minas Gerais, por meio da análise de conteúdo dos relatos de Profissionais de Saúde e Gestores sobre as ações padronizadas na instituição dentro das práticas da Rede Cegonha, além de verificar a existência de rotina de analgesia para partos normais nessa instituição pelos (Profissionais de Saúde, Gestores, Gestantes e Puérperas). Tratou-se de uma pesquisa diagnóstica de caráter exploratório e abordagem quanti-qualitativa, com análise bibliográfica e de campo, contando com um questionário semi-estruturado.  A análise dos dados mostrou que não houve diferença significativa entre as respostas providas pelos participantes em nenhuma das situações analisadas, demonstrando uma similaridade de respostas de profissionais e gestores em relação à existência de ações padronizadas na instituição dentro das práticas da Rede Cegonha, e o desconhecimento das três categorias em relação à inexistência de rotina de analgesia para o parto normal.

Holy Anointing Oil Tradition in Eastern Orthodox Church Perspective
Authors: Steve Kalalo John Abraham , Ricky Sutjiadi
Published: May 2023

The fact that there are many different types of holy anointing oil available for purchase suggests that there is a high demand for this traditional practice. To gain a better understanding of this tradition, it would be helpful to examine its ancient roots. This article focuses on the use, purpose, and meaning of holy anointing oil within the Eastern Orthodox Church. This church is one of the oldest religious institutions that practices this tradition. The research method employed in this study is qualitative and involves a thorough review of relevant literature. By the end of this investigation, the article aims to explore the biblical perspective on holy anointing oil and how the tradition is viewed within this context. The Epistle of James is one of the most frequently cited texts concerning the use of anointing oil. According to James, the central theme of the letter is the importance of combining faith with good deeds.

Published: May 2023

Objetivo: buscou-se avaliar a concordância entre o Sistema de Informação de Agravo de Notificação (SINAN) e dados policiais para casos de violência física e sexual contra mulheres, bem como o perfil das mulheres agredidas, das agressões e dos agressores. Método: foi realizado estudo transversal com casos ocorridos em uma cidade de Minas Gerais, notificados no SINAN e/ou identificados na base policial, entre os anos de 2015 e 2016. Criou-se uma base consolidada, composta pelos casos elegíveis das duas fontes, tendo sido realizadas análises descritivas. Em uma base pareada contendo casos comuns aos dois bancos, foi realizada análise de concordância pelo teste Fleiss’Kappa. Resultados: 1.185 casos compuseram a base consolidada e 56 constituíram a base pareada. Houve sub-registro de 83,54% nos dados do SINAN, além de incompletude importante de informações. A base policial apresentou cerca de oito vezes maior captação. A concordância de informações foi elevada/moderada para sete de 11 características avaliadas para os casos comuns. Na base consolidada, as vítimas foram predominantemente negras, solteiras ou viúvas, com idade entre 18 e 39 anos. Os homens, especialmente (ex)parceiros e familiares, foram os principais agressores. Conclusão: o sub-registro e a incompletude de informações sobre violência contra mulher no SINAN é uma realidade que precisa ser tratada. O cruzamento com fontes de dados policiais é uma alternativa para melhorar a qualidade das informações, reduzindo o sub-registro. Apesar dos dados subestimados, percebeu-se que a violência física e doméstica, cometida por (ex)parceiro contra mulheres jovens e negras continua sendo prevalente, atentando para o fato que se deve manter foco de políticas públicas.

التوليد الشكلي في بنية الذؤابات الزخرفية

Published: May 2023

من المعروف أن الفن العربي الإسلامي فن زخرفي, نما على يد الفنانين المسلمينحيث أنصرفوا عن رسم الكائنات الحية لكراهيتها سيما بالعهود الأولى للإسلام؛ مما أدىذلك الى أستخدام زخارف أخرى متنوعة(هندسية - نباتية- نصية خطية)؛ تجسدت بتزيينالقرآن الكريم والعمارة الاسلامية؛ وبمرور الزمن تطورت تلك الزخارف؛ فحملت في بنيةوحداتها وعناصرها الشكلية ميزة وصفت بطابعها الزخرفي الإسلامي. حيث جاعت الذؤابات كشكل متمم للعمل الزخرفي الخطي؛ أذ شكلت بمجموعتهاالشخصية المتكاملة حقلا تزينيا مهما ساعدت على تجميل كثير من التطبيقات على صعيدالمنجزات الخطية حيث استلهمت فنيا وعولجت تصميميا لتلبي الأهداف الجمالية والذوقية؛وذلك انطلاقا من التنوع والتباين الناشئين في بنيتها التصميمية للمفردات والعناصرالمعتمدة فيها وحتى داخل الاتجاه الواحد، فضلا عن وجود توالدات شكلية مختلفة تتمثلبها الذؤابات الزخرفية وهي كما يأتي:-‎١‏ ذؤابات زخرفية نباتية( غصنية- كأسية- زهرية).7" ذؤابات زخرفية هندسية.‎٣‏ ذؤابات زخرفية مزدوجة(نباتية- هندسية). واعتمدت هذه التوالدات الشكلية في تطبيقات كثيرة سيما اللوحات الخطية التي تعدميدان بحثنا هذا. حيث وجد الباحث أن من الصعوبات التي تواجهه في هذا الميدان هو التنوع الكبيرللتصاميم المنفذة. فضلا عن كثرتها ولن نبالغ أذا قلنا أن ليس هناك من النماذج ما يمكنأن تطمئن على أن يكون مثلا وافيا لهذا التنوع للذؤابات الزخرفية؛ بمعنى أن تتجسد فيهكل الاحتمالات التصميمية المنفذة فعلاء وفي ضوء ذلك أجتهد الباحث أن يركز جهده على
