Adaptability Assessment and Analysis of Temporal and Spatial Differences of Water-Energy-Food System in Yangtze River Delta in China
Authors: Han Zichen , Ma Hailiang
Published: December 2021

Serving as an effective tool for research on regional sustainable development, adaptive management has become the subject of global climate change and environmental economic research nowadays. Based on the perspective of the adaptability of the composite system, this article decomposes the adaptability into four aspects: sensibility, stability, compatibility and sustainability. We use the pressure-state-impact-response (PSIR) model to construct a Comprehensive Index Evaluation System for the adaptability of the Water-Energy-Food System in the Yangtze River Delta from 2010 to 2019. Our analyses show that: Firstly, the adaptability of the Water-Energy-Food System in the Yangtze River Delta fluctuates greatly, with the lowest value being only 33.35% of the highest value. Secondly, while sensibility shows an “M-shaped” development trend, the stability, sustainability and compatibility of the Water-Energy-Food System in the Yangtze River Delta changes simultaneously, showing a “U-shaped” development trend as a whole. Thirdly, there exists significant spatial differences in the adaptability of the Water-Energy-Food System in the Yangtze River Delta. Zhejiang Province has the highest level of system adaptability, while Anhui Province has the lowest. Based on that, we recommend to strengthen the coordinated management of various departments and natural resources in the Yangtze River Delta and implement strict red lines for resource utilization and environmental protection.

Authors: Ekster Alex , Alchakov Vasiliy , Meleshin Ivan , Larionenko Alexandr
Published: December 2021

Control of airflow of activated sludge systems has significant challenges due to the non-linearity of the control element (butterfly valve). To overcome this challenge, some valve manufacturers developed valves with linear characteristics. However, these valves are 10–100 times more expensive than butterfly valves. By developing models for butterfly valves installed characteristics and utilizing these models for real-time airflow control, the authors of this paper aimed to achieve the same accuracy of control using butterfly valves as achieved using valves with linear characteristics. Several approaches were tested to model the installed valve’s characteristics, such as a formal mathematical model utilizing Simscape/Matlab software, a semi-empirical model, and several machine learning methods (MLM), including regression, support vector machine, Gaussian process, decision tree, and deep learning. Several versions of the airflow-valve position models were developed using each machine learning method listed above. The one with the smallest forecast error was selected for field testing at the 55.5×103 m3/day 12 MGD City of Chico activated sludge system. Field testing of the formal mathematical model, semi-empirical model, and the regularized gradient boosting machine model (the best among MLMs) showed that the regularized gradient boosting machine model (RGBMM) provided the best accuracy. The use of the RGBMMs in airflow control loops since 2019 at the City of Chico wastewater treatment plant showed that these models are robust and accurate (2.9% median error).
Technological Transformation Processes and Resistance—On the Conflict Potential of 5G Using the Example of 5G Network Expansion in Germany
Authors: Jenal Corinna , Endreß Sven , Kühne Olaf , Zylka Caroline
Published: December 2021

The expansion of fifth-generation wireless technology (5G) has been assigned the significance of a ‘key technology’ in connection with technological advances in the context of the digitalization of societies, which is a central goal of current governments in leading industrialized nations. As with other large-scale infrastructure projects such as the expansion of renewable energies as part of the energy transition in Germany, the plans for implementation are meeting with great resistance from the population, sometimes resulting in arson attacks on 5G transmission masts. Current research on 5G focuses primarily on technical–economic, health-related and, in the context of the COVID-19 pandemic, increasingly conspiracy-theoretical aspects, while questions of acceptance or conflict potential have received little attention to date. This article aims to address this research gap and, on the basis of a conflict-theoretical perspective according to Dahrendorf combined with a socio-economic contextualization in the sense of Bourdieu, approaches the question of the extent to which social conflict has already progressed and what regulatory possibilities socio-economic contexts assume in terms of significance. For this purpose, about 70 identifiable internet presences of citizens’ initiatives against 5G were qualitatively and quantitatively evaluated.
Sustainable Team Design: A Challenge to Traditional Beliefs in Information-Intensive Service Industries
Authors: Geoghegan Mark , Cormican Kathryn , Wu Qiong
Published: December 2021

Sustainable management activities focus on creating value for organizations. This is particularly relevant in service organizations as they are under increasing pressure to capture and process information efficiently. We advocate that the amount of information and the way teams process this information have a substantial impact on an organization’s ability to sustain a competitive advantage. This study addresses a gap in the literature by examining the impact of the level of information intensity on performance in the service industry. It also contributes to the debate about whether team structure facilitates performance in a service-based organization. A longitudinal design was employed to determine whether information-intensive processes influence performance, and if so, whether the impact differs between team designs. To do this, data were collected from 24,925 motor insurance claims over two distinct time periods. While our findings confirm that information intensity has a direct impact on the performance of claims processing, they also challenge traditional beliefs about self-managed work teams’ dominance. By adopting a more nuanced and context-specific perspective, we discovered that in certain situations the production line approach to team design was more productive than self-directed work teams in respect to critical operational tasks. This research sheds light on a relatively unexplored aspect of the service industry, has implications for sustainable management practices relating to team design, and provides a rich vein for future research studies.

Published: December 2021

It is a well-known fact that convex and non-convex fuzzy mappings play a critical role in the study of fuzzy optimization. Due to the behavior of its definition, the idea of convexity also plays a significant role in the subject of inequalities. The concepts of convexity and symmetry have a tight connection. We may use whatever we learn from both the concepts, owing to the significant correlation that has developed between both in recent years. In this paper, we introduce a new class of harmonically convex fuzzy-interval-valued functions which is known as harmonically h-convex fuzzy-interval-valued functions (abbreviated as harmonically h-convex F-I-V-Fs) by means of fuzzy order relation. This fuzzy order relation is defined level-wise through Kulisch–Miranker order relation defined on interval space. Some properties of this class are investigated. BY using fuzzy order relation and h-convex F-I-V-Fs, Hermite–Hadamard type inequalities for harmonically are developed via fuzzy Riemann integral. We have also obtained some new inequalities for the product of harmonically h-convex F-I-V-Fs. Moreover, we establish Hermite–Hadamard–Fej’er inequality for harmonically h-convex F-I-V-Fs via fuzzy Riemann integral. These outcomes are a generalization of a number of previously known results, as well as many new outcomes can be deduced as a result of appropriate parameter “θ” and real valued function “∇” selections. For the validation of the main results, we have added some nontrivial examples. We hope that the concepts and techniques of this study may open new directions for research.
Circuit Topology for Bottom-Up Engineering of Molecular Knots
Authors: Golovnev Anatoly , Mashaghi Alireza
Published: December 2021

The art of tying knots is exploited in nature and occurs in multiple applications ranging from being an essential part of scouting programs to engineering molecular knots. Biomolecular knots, such as knotted proteins, bear various cellular functions, and their entanglement is believed to provide them with thermal and kinetic stability. Yet, little is known about the design principles of naturally evolved molecular knots. Intra-chain contacts and chain entanglement contribute to the folding of knotted proteins. Circuit topology, a theory that describes intra-chain contacts, was recently generalized to account for chain entanglement. This generalization is unique to circuit topology and not motivated by other theories. In this conceptual paper, we systematically analyze the circuit topology approach to a description of linear chain entanglement. We utilize a bottom-up approach, i.e., we express entanglement by a set of four fundamental structural units subjected to three (or five) binary topological operations. All knots found in proteins form a well-defined, distinct group which naturally appears if expressed in terms of these basic structural units. We believe that such a detailed, bottom-up understanding of the structure of molecular knots should be beneficial for molecular engineering.
Asymmetric Density for Risk Claim-Size Data: Prediction and Bimodal Data Applications
Authors: Shrahili Mansour , Elbatal Ibrahim , M. Yousof Haitham
Published: December 2021

A new, flexible claim-size Chen density is derived for modeling asymmetric data (negative and positive) with different types of kurtosis (leptokurtic, mesokurtic and platykurtic). The new function is used for modeling bimodal asymmetric medical data, water resource bimodal asymmetric data and asymmetric negatively skewed insurance-claims payment triangle data. The new density accommodates the “symmetric”, “unimodal right skewed”, “unimodal left skewed”, “bimodal right skewed” and “bimodal left skewed” densities. The new hazard function can be “decreasing–constant–increasing (bathtub)”, “monotonically increasing”, “upside down constant–increasing”, “monotonically decreasing”, “J shape” and “upside down”. Four risk indicators are analyzed under insurance-claims payment triangle data using the proposed distribution. Since the insurance-claims data are a quarterly time series, we analyzed them using the autoregressive regression model AR(1). Future insurance-claims forecasting is very important for insurance companies to avoid uncertainty about big losses that may be produced from future claims.
FumDSB Can Reduce the Toxic Effects of Fumonisin B1 by Regulating Several Brain-Gut Peptides in Both the Hypothalamus and Jejunum of Growing Pigs
Authors: Liu Quancheng , Li Fuchang , Huang Libo , Chen Wenjie , Li Zhongyuan , Wang Chunyang
Published: December 2021

Fumonisin B1 (FB1) is the most common food-borne mycotoxin produced by the Fusarium species, posing a potential threat to human and animal health. Pigs are more sensitive to FB1 ingested from feed compared to other farmed livestock. Enzymatic degradation is an ideal detoxification method that has attracted much attention. This study aimed to explore the functional characteristics of the carboxylesterase FumDSB in growing pigs from the perspective of brain–gut regulation. A total of 24 growing pigs were divided into three groups. The control group was fed a basal diet, the FB1 group was supplemented with FB1 at 5 mg/kg feed, and the FumDSB group received added FumDSB based on the diet of the FB1 group. After 35 days of animal trials, samples from the hypothalamus and jejunum were analyzed through HE staining, qRT-PCR and immunohistochemistry. The results demonstrated that the ingestion of FB1 can reduce the feed intake and weight gain of growing pigs, indicating that several appetite-related brain-gut peptides (including NPY, PYY, ghrelin and obestatin, etc.) play important roles in the anorexia response induced by FB1. After adding FumDSB as detoxifying enzymes, however, the anorexia effects of FB1 were alleviated, and the expression and distribution of the corresponding brain-gut peptides exhibited a certain degree of regulation. In conclusion, the addition of FumDSB can reduce the anorexia effects of FB1 by regulating several brain-gut peptides in both the hypothalamus and the jejunum of growing pigs.
QCD Effective Locality: A Theoretical and Phenomenological Review
Authors: Fried Herbert M. , Gabellini Yves , Grandou Thierry , Tsang Peter H.
Published: December 2021

About ten years ago, the use of standard functional manipulations was demonstrated to imply an unexpected property satisfied by the fermionic Green’s functions of QCD and dubbed Effective Locality. This feature of QCD is non-perturbative, as it results from a full gauge invariant integration of the gluonic degrees of freedom. In this review article, a few salient theoretical aspects and phenomenological applications of this property are summarized.
Differential Accumulation of Misfolded Prion Strains in Natural Hosts of Prion Diseases
Authors: Lambert Zoe J. , Greenlee Justin J. , Cassmann Eric D. , West Greenlee M. Heather
Published: December 2021

Prion diseases, also known as transmissible spongiform encephalopathies (TSEs), are a group of neurodegenerative protein misfolding diseases that invariably cause death. TSEs occur when the endogenous cellular prion protein (PrPC) misfolds to form the pathological prion protein (PrPSc), which templates further conversion of PrPC to PrPSc, accumulates, and initiates a cascade of pathologic processes in cells and tissues. Different strains of prion disease within a species are thought to arise from the differential misfolding of the prion protein and have different clinical phenotypes. Different strains of prion disease may also result in differential accumulation of PrPSc in brain regions and tissues of natural hosts. Here, we review differential accumulation that occurs in the retinal ganglion cells, cerebellar cortex and white matter, and plexuses of the enteric nervous system in cattle with bovine spongiform encephalopathy, sheep and goats with scrapie, cervids with chronic wasting disease, and humans with prion diseases. By characterizing TSEs in their natural host, we can better understand the pathogenesis of different prion strains. This information is valuable in the pursuit of evaluating and discovering potential biomarkers and therapeutics for prion diseases.
Maternal HPV Infection: Effects on Pregnancy Outcome
Authors: Condrat Carmen Elena , Filip Lidia , Gherghe Mirela , Cretoiu Dragos , Suciu Nicolae
Published: December 2021

The human papilloma virus (HPV) infection, caused by a ubiquitous virus typically transmitted through the direct contact of infected organs, either through the skin or mucosa, is the most common sexually transmitted infection, placing young women at a high risk of contracting it. Although the vast majority of cases spontaneously clear within 1–2 years, persistent HPV infection remains a serious concern, as it has repeatedly been linked to the development of multiple malignancies, including cervical, anogenital, and oropharyngeal cancers. Additionally, more recent data suggest a harmful effect of HPV infection on pregnancy. As the maternal hormonal environment and immune system undergo significant changes during pregnancy, the persistence of HPV is arguably favored. Various studies have reported an increased risk of adverse pregnancy outcomes among HPV-positive women, with the clinical impact encompassing a range of conditions, including preterm birth, miscarriage, pregnancy-induced hypertensive disorders (PIHD), intrauterine growth restriction (IUGR), low birth weight, the premature rupture of membranes (PROM), and fetal death. Therefore, understanding the mechanisms employed by HPV that negatively impact pregnancy and assessing potential approaches to counteract them would be of interest in the quest to optimize pregnancy outcomes and improve child survival and health.

Published: December 2021

Background: We evaluated how plasma proteomic signatures in patients with suspected COVID-19 can unravel the pathophysiology, and determine kinetics and clinical outcome of the infection. Methods: Plasma samples from patients presenting to the emergency department (ED) with symptoms of COVID-19 were stratified into: (1) patients with suspected COVID-19 that was not confirmed (n = 44); (2) non-hospitalized patients with confirmed COVID-19 (n = 44); (3) hospitalized patients with confirmed COVID-19 (n = 53) with variable outcome; and (4) patients presenting to the ED with minor diseases unrelated to SARS-CoV-2 infection (n = 20). Besides standard of care diagnostics, 177 circulating proteins related to inflammation and cardiovascular disease were analyzed using proximity extension assay (PEA, Olink) technology. Results: Comparative proteome analysis revealed 14 distinct proteins as highly associated with SARS-CoV-2 infection and 12 proteins with subsequent hospitalization (p < 0.001). ADM, IL-6, MCP-3, TRAIL-R2, and PD-L1 were each predictive for death (AUROC curve 0.80–0.87). The consistent increase of these markers, from hospital admission to intensive care and fatality, supported the concept that these proteins are of major clinical relevance. Conclusions: We identified distinct plasma proteins linked to the presence and course of COVID-19. These plasma proteomic findings may translate to a protein fingerprint, helping to assist clinical management decisions.

Authors: Falco Alberto , Bello-Perez Melissa , Díaz-Puertas Rocío , Mold Matthew , Adamek Mikolaj
Published: December 2021

Viral nervous necrosis (VNN) caused by the nervous necrosis virus (NNV) affects a broad range of primarily marine fish species, with mass mortality rates often seen among larvae and juveniles. Its genetic diversification may hinder the effective implementation of preventive measures such as vaccines. The present study describes different inactivation procedures for developing an inactivated vaccine against a new NNV isolate confirmed to possess deadly effects upon the European seabass (Dicentrarchus labrax), an important Mediterranean farmed fish species that is highly susceptible to this disease. First, an NNV isolate from seabass adults diagnosed with VNN was rescued and the sequences of its two genome segments (RNA1 and RNA2) were classified into the red-spotted grouper NNV (RGNNV) genotype, closely clustering to the highly pathogenic 283.2009 isolate. The testing of different inactivation procedures revealed that the virus particles of this isolate showed a marked resistance to heat (for at least 60 °C for 120 min with and without 1% BSA) but that they were fully inactivated by 3 mJ/cm2 UV-C irradiation and 24 h 0.2% formalin treatment, which stood out as promising NNV-inactivation procedures for potential vaccine candidates. Therefore, these procedures are feasible, effective, and rapid response strategies for VNN control in aquaculture.

Published: December 2021

Vaccine hesitancy is one of the top ten greatest threats to global health. During the COVID-19 era, vaccine hesitancy poses substantial risks, especially in visible minorities, who are disproportionately affected by the pandemic. Although evidence of vaccine hesitancy exists, there is minimal focus on visible minorities and the reasons for hesitancy in this group are unclear. Identifying these populations and their reasons for vaccine hesitancy is crucial in improving vaccine uptake and curbing the spread of COVID-19. This scoping review follows a modified version of the Arksey and O’Malley strategy. Using comprehensive search strategies, advanced searches were conducted on Medline, CINAHL, and PubMed databases to acquire relevant articles. Full-text reviews using inclusion and exclusion criteria were performed to extract themes of vaccine hesitancy. Themes were grouped into factors using thematic qualitative analysis and were objectively confirmed by principal component analysis (PCA). To complement both analyses, a word cloud of titles and abstracts for the final articles was generated. This study included 71 articles. Themes were grouped into 8 factors and the top 3 recurring factors were safety and effectiveness of the vaccine, mistrust, and socioeconomic characteristics. Shedding light on these factors could help mitigate health inequities and increase overall vaccine uptake worldwide through interventions and policies targeted at these factors. Ultimately, this would help achieve global herd immunity.

Published: December 2021

Dissolved organic matter (DOM) has a great impact on the main pollution indicators of lakes (such as chemical oxygen demand, COD). Therefore, DOM is the research basis for understanding the meaning of the water environment and the laws of the migration and transformation of pollutants. Qinghai Lake is one of the world’s typical inland plateau lake wetlands. It plays important roles in improving and regulating the climate and in promoting a virtuous regional ecological cycle. In recent years, with the acceleration of urbanization and the rapid development of tourism, under the background of climate change, and with grassland degradation and precipitation change, the whole basin of Qinghai Lake has been facing great ecological pressure. In order to comprehensively explore the water environment of Qinghai Lake and to protect the sustainable development of the basin, a systematic study was carried out on the whole basin of Qinghai Lake. The results show the following: (1) from 2010 to 2020, the annual average value of CODCr in Qinghai Lake fluctuated in the range from class III to class V according to the surface water environmental quality standard, showing first a downward trend and then an upward trend. (2) The concentration of CDOM in Qinghai Lake had obvious temporal and spatial changes. (3) The spatial distribution of the total fluorescence intensity of FDOM in water was also different in different seasons. However, in the three surveys, the area with the highest total fluorescence intensity of FDOM in the water body appeared near Erlangjian in the south of Qinghai Province, indicating that anthropogenic sources are the main controlling factors of dissolved organic matter in the lake.

The Indian subcontinent is annually affected by floods that cause profound irreversible damage to crops and livelihoods. With increased incidences of floods and their related catastrophes, the design, development, and deployment of an Early Warning System for Flood Prediction (EWS-FP) for the river basins of India is needed, along with timely dissemination of flood-related information for mitigation of disaster impacts. Accurately drafted and disseminated early warnings/advisories may significantly reduce economic losses incurred due to floods. This study describes the design and development of an EWS-FP using advanced computational tools/methods, viz. HPC, remote sensing, GIS technologies, and open-source tools for the Mahanadi River Basin of India. The flood prediction is based on a robust 2D hydrodynamic model, which solves shallow water equations using the finite volume method. The model is open-source, supports geographic file formats, and is capable of simulating rainfall run-off, river routing, and tidal forcing, simultaneously. The model was tested for a part of the Mahanadi River Basin (Mahanadi Delta, 9225 sq km) with actual and predicted discharge, rainfall, and tide data. The simulated flood inundation spread and stage were compared with SAR data and CWC Observed Gauge data, respectively. The system shows good accuracy and better lead time suitable for flood forecasting in near-real-time.

Basic Income in the Pandemic Era: Another False Start or a New Paradigm of Social Policy?
Authors: Kvashnin Yury Dmitrievich
Published: December 2021

The article examines the current debate around the concept of an unconditional basic income (UBI) and the prospects for its implementation in the context of heightened social challenges. The growing wealth inequality, the precarization of work, as well as the threat of technological unemployment — all these issues have caused a new wave of interest in universal approaches to the development of social systems. This wave reached its peak during the COVID-19 pandemic, which required emergency measures to support the economy and employment. In a number of countries, the idea of a complete or partial transition from traditional social protection schemes to equal payments for all has gained wide public support and was included in the programs of influential political parties. Many new experiments have been planned or are already under way to assess the UBI’s potential positive and negative effects. The major stumbling block, however, is the problem of funding. Analyzing the proposals put forward in the academic, expert and political communities, the author of the article comes to the conclusion that the transition to a full-fledged UBI even in the most developed countries will be associated with an unacceptable increase in the budget deficit and government debt. A more realistic scenario is the gradual incorporation of certain elements of basic income into existing social systems. Possible approaches here are: the provision of modest benefits, significantly below the national poverty line; payments in favor of particularly vulnerable population groups; implementation of UBI as an emergency measure for a limited period of time.

Este artículo analiza los efectos del salario básico unificado sobre la calidad de vida de los habitantes del cantón Santa Ana de la provincia de Manabí durante el periodo 2007 – 2017, se ha utilizado la tasa de pobreza del cantón como variable proxy del nivel socioeconómico. De acuerdo a la teoría económica, los salarios regulados por ley pueden tener un efecto positivo sobre la economía al reducir las brechas de desigualdad salarial, pero también puede causar problemas como el desempleo. Debido a la poca información a nivel cantonal, este estudio aplica un análisis de covarianza y de correlación de Pearson para encontrar una relación entre el salario y la pobreza. Los resultados sugieren una relación inversa entre el crecimiento salarial y la tasa de pobreza del cantón, por lo que hay un efecto positivo del salario básico sobre el nivel socioeconómico de los habitantes del cantón.

ABSTRACT

 

This article analyzes the effects of the unified basic salary on the quality of life of the inhabitants of Santa Ana during the period 2007-2017. To achieve our goal, we take the poverty rate as a proxy for the socioeconomic status. According to economic theory, wages regulated by law can have a positive effect on the economic growth but also can cause problems such as unemployment. Due to the limited information at cantonal level, this study applies a covariance analysis and a Pearson correlation analysis to find a relationship between salary and poverty. The results suggest an inverse relationship between wage growth and poverty rate. So, there is a positive effect of the basic salary on the socioeconomic level of the inhabitants of Santa Ana.

 

Key words: unified basic salary; socioeconomic status; poverty; Santa Ana.

La presente investigación tiene como objetivo analizar el capital de trabajo y el impacto en la rentabilidad de la industria de alimentos Tsáchila “El Gustador”. La metodología utilizada tuvo un enfoque mixto y es de carácter no experimental, descriptivo y explicativo, por lo que se implementaron técnicas como la encuesta, entrevista y observación para la recolección de datos, los mismos que después de haber sido analizados e interpretados mostraron que existen deficiencias respecto a la administración de las cuentas del activo y pasivo a corto plazo, situación que afecta directamente a la liquidez de la industria y la determinación de inversión en el capital de trabajo; identificando que este hecho tiene su origen por una deficiente gestión del inventario y de las cuentas por cobrar pudiendo afectar en un futuro a las ventas de la empresa y por ende a su rentabilidad.
