Current Impediments for New England DOTs to Transition to Sustainable Roadside Practices for Strengthening Pollinator Habitats and Health
Authors: Campanelli John , Kuzovkina Yulia A. , Kocurek Samuel
Published: February 2023

Government agencies whose work impacts the environment have sought more sustainable policy changes that require the use of native plants for revegetation. However, New England DOTs have encountered hurdles in attempts to transition from using cool-season turfgrass to implementing the more complicated management practices required to establish native plant communities. Two of the most significant barriers have been the slow transition to mainly using native plants for revegetation and the lack of genetically appropriate ecotypic native plant material (ENPM) produced in the Northeast. Growers of ENPM have resisted increasing production because they struggle to gauge demand due to substantial communication gaps between local producers and end users. Therefore, we organized focus groups with New England state DOTs, Departments of Environmental Protection, and Fish and Wildlife Services to determine their demand for ENPM and to explore their relationships with producers. We determined that the subcontracting of DOTs hinders their ability to develop relationships with producers because it leaves seed source selection in the hands of third parties. Another impediment was found to be the resistance of some maintenance departments to adopt sustainable management practices, such as reduced mowing. In summary, we determined that DOTs would benefit from establishing more direct relationships with producers to communicate their ENPM needs.
An Empirical Study on the Relationship between Corporate Social Responsibility and Default Risk: Evidence in Korea
Authors: Suganda Tarsisius Renald , Kim Jungmu
Published: February 2023

Focusing on the Korean stock market, this paper expands on previous research on the relationship between corporate social responsibility (CSR) and default risk. By using a comprehensive sample of 6977 firm-year observations during the 2011–2021 period, we employ the year fixed effects and industrial sector dummies classified by FnGuide Industry Classification Standard to control for shifting economic conditions over time and effects within industries. The Z-score is employed as the primary proxy for default risk, and the finding of the study confirms a negative association between CSR practices and default risk. Moreover, testing the three components of CSR, we also find that each component has a negative impact on the default risk. To ensure the robustness of our findings, we conduct a robustness check using two additional proxies of default risk: the K-score, a specific measure of default risk for the Korean market, and the distance to default (DTD), a market-based model. Our results remain consistent and robust even when utilizing alternative proxies, further confirming the negative relationship between CSR and default risk. This has significant implications for businesses and regulators who aim to decrease the risk of default through implementing CSR initiatives.
Supply Chain Performance with a Downside-Risk-Averse Retailer and Strategic Customers
Authors: Zhao Ling , Zou Anquan , Xiong Minghua , Liu Jun
Published: February 2023

Predicting future promotion information on markdowns, customers can maximize their utilities by deciding when to buy. With this strategic behavior, this paper investigates a downside-risk-averse retailer’s integrated stock and pricing problem using a single case study method. Analyzing effects of the downside risk aversion and strategic customers is our purpose. By exploring a two-phase newsvendor model with a retailer selling to strategic customers, our work determines the downside-risk-averse retailer’s equilibrium ordering level and selling price. On this basis, effects of the downside risk aversion and the strategic behavior on the retailer’s optimum decisions and profit are analyzed. We find that the reverse effect of the strategic behavior can be mitigated by the retailer’s downside risk constraint. We also extend the model to a decentralized supply chain case. It is found that a low (high) downside risk aversion would mean that the supply chain profit in the decentralized case can (cannot) dominate the centralized under some (any) wholesale price contracts when customers are strategic. In addition, for different risk aversions, we also construct contracts to optimize the supply chain profit. Our results will provide reference evidence of making operational management decisions for the downside-risk-averse retailer in the case of strategic customers.
Energy and Economic Savings Assessment of Energy Refurbishment Actions in Italian Residential Buildings: Comparison between Asset and Tailored Calculation
Authors: Palladino Domenico , Di Turi Silvia
Published: February 2023

Residential buildings have become one of the leading sectors in the energy refurbishment process towards the clean energy transition. Energy Performance Certificates (EPCs), based on the asset rating calculation method, are often used to quantify the energy performance in standard conditions before and after renovation, but their energy outcomes can significantly differ from the actual energy consumption and savings. More consistent results can be obtained by adopting a “tailored” approach, capable of considering more the actual building operation conditions and users’ behaviour. In this framework, the study evaluates the heating energy needs of Italian representative multi-family houses in all the climatic zones and five retrofitting scenarios with both asset and tailored ratings. Finally, a cost–benefit analysis, based on energy savings and interventions costs, is also carried out to assess the affordability of the refurbishment actions depending on the adopted calculation methods. The analysis of retrofitting scenarios highlighted that asset energy outcomes are generally slightly greater than the tailored ones (differences of around 3–13% on average), but the affordability of the chosen energy efficiency measures is significantly overrated. It could underline the need to adopt the tailored approach for more accurate energy savings assessment and economic evaluation.

Authors: Liu Jingjing , Zhao Min , Zhang Chao , Ren Fangrong
Published: February 2023

Since its reform and opening up, China’s economy has undergone rapid development and has experienced problems such as the overexploitation of resources and the destruction of the ecological environment. To achieve a balance between economic growth and environmental protection and to follow the sustainable development path, China must implement corresponding environmental regulation policies and vigorously encourage enterprises to pursue green technology innovation. In this paper, environmental regulation is divided into command-and-control, market incentive and voluntary participation. Command-and-control environmental regulation is measured using the entropy method and the logarithm of the pollution discharge fee income in each region is used as the measurement index of market-incentive environmental regulations. At the same time, the logarithm of the number of environmental protection proposals planned by the National People’s Congress and the number of environmental protection proposals planned by the CPPCC is used as the measurement index of voluntary participation in environmental regulations. Based on a regression equation of the effects of environmental regulations on green technology innovation, this paper uses the two-step system GMM method to analyze the panel data of industrial enterprises larger than a designated size in 30 provinces, autonomous regions and municipalities in China from 2006 to 2017. Moreover, the paper compares the effects of command-and-control, market-incentive and voluntary participatory environmental regulations on green technology innovation. The empirical results show that command-and-control environmental regulations initially have an inverted U-shaped effect on green technology innovation and market incentive and voluntary participatory environmental regulations have a U-shaped effect on green technology innovation. A comparison of the three environmental regulation policies shows that the effect of command-and-control environmental regulation is more significant.
The Power of Financial Incentives versus the Power of Suggestion for Individual Pension: Are Financial Incentives or Automatic Enrollment Policies More Effective?
Authors: Yanıkkaya Halit , Aktaş Koral Zeynep , Çitçi Sadettin Haluk
Published: February 2023

This study investigates and compares the impacts of two important reforms in retirement savings—matching contribution and automatic enrollment—on participation in the individual pension system (IPS) in Turkey by using a dataset containing information about over 40 million pension contracts for the period of 2004–2021. Unlike the automatic enrollment system (AES), the state matching contribution policy imposes a burden on the state’s budget; understanding the relative effectiveness of the two policies can help protect the public budget from such burdens, especially by taking individual attitudes into account in future policy recommendations. Our estimations indicate that both reforms led to an overall increase in participation. However, the AES is not efficient at encouraging participants to make an active decision on plan characteristics, such as portfolio choices. We also evaluate the effects of the two reforms on IPS participation among different demographic groups. We find that males and married individuals are more responsive to matching contributions, and education levels seem to be closely related with IPS participation. Participants are also sensitive to both the returns of pension funds and alternative investment instruments. All the findings imply that individuals must be encouraged to recognize the need for effective financial preparation in their post-retirement lives. To accomplish this, policymakers could utilize a comprehensive informative campaign and workplace seminars about both the system as a whole and the returns, and they could improve the plan characteristics to be compatible with the needs of individuals before retirement as well as after.
Transfer and Unsupervised Learning: An Integrated Approach to Concrete Crack Image Analysis
Authors: Gradišar Luka , Dolenc Matevž
Published: February 2023

The detection of cracks in concrete structures is crucial for the assessment of their structural integrity and safety. To this end, detection with deep neural convolutional networks has been extensively researched in recent years. Despite their success, these methods are limited in classifying concrete as cracked or non-cracked and disregard other characteristics, such as the severity of the cracks. Furthermore, the classification process can be affected by various sources of interference and noise in the images. In this paper, an integrated methodology for analysing concrete crack images is proposed using transfer and unsupervised learning. The method extracts image features using pre-trained networks and groups them based on similarity using hierarchical clustering. Three pre-trained networks are used for this purpose, with Inception v3 performing the best. The clustering results show the ability to divide images into different clusters based on image characteristics. In this way, various clusters are identified, such as clusters containing images of obstruction, background debris, edges, surface roughness, as well as cracked and uncracked concrete. In addition, dimensionality reduction is used to further separate and visualise the data, making it easier to analyse clustering results and identify misclassified images. This revealed several mislabelled images in the dataset used in this study. Additionally, a correlation was found between the principal components and the severity of cracks and surface imperfections. The results of this study demonstrate the potential of unsupervised learning for analysing concrete crack image data to distinguish between noisy images and the severity of cracks, which can provide valuable information for building more accurate predictive models.
Contamination, Ecological Risk and Source Apportionment of Heavy Metals in the Surface Sediments in the Hailar River, the Upper Source of the Erguna River between China and Russia
Authors: Xie Yufeng , Huo Xiaodong , Hu Chuanhai , Tao Yuqiang
Published: February 2023

The concentrations of heavy metals (As, Cd, Cr, Cu, Hg, Ni, Pb and Zn) in 17 surface sediment samples from the Hailar River, the upper source of the Ergun River, which is the boundary river between China and Russia, were analyzed. Traceability and cause analysis of heavy metals in sediment were carried out by correlation analysis and principal component analysis. The results showed that the concentrations of Hg and Cd in sediments exceeded the soil background values. Due to the high biological toxicity factor of Hg, Hg is the highest potential ecological risk factor in the Hailar River and its tributary the Yimin River. The sources of Hg and As were likely to come from human activities including mining, coal burning and animal husbandry; other HMs, especially Zn and Cr, mainly come from mining and natural factors. Due to the high level of urbanization and more agricultural activities, the pollution potential of Cd, Hg and Pb in the Yimin River and the lower reaches of the Hailar River was greater. The results of this study will help to understand the distribution and pollution of heavy metals in river sediments in the basin and provide management support for China’s local environmental management departments and relevant national departments of China.
Video Anomaly Detection Based on Attention Mechanism
Authors: Zhang Qianqian , Wei Hongyang , Chen Jiaying , Du Xusheng , Yu Jiong
Published: February 2023

Camera surveillance is widely used in residential areas, highways, schools and other public places. The monitoring and scanning of sudden abnormal events depend on humans. Human anomaly monitoring not only consumes a lot of manpower and time but also has a large error in anomaly detection. Video anomaly detection based on AE (Auto-Encoder) is currently the dominant research approach. The model has a highly symmetrical network structure in the encoding and decoding stages. The model is trained by learning standard video sequences, and the anomalous events are later determined in terms of reconstruction error and prediction error. However, in the case of limited computing power, the complex model will greatly reduce the detection efficiency, and unnecessary background information will seriously affect the detection accuracy of the model. This paper uses the AE loaded with dynamic prototype units as the basic model. We introduce an attention mechanism to improve the feature representation ability of the model. Deep separable convolution operation can effectively reduce the number of model parameters and complexity. Finally, we conducted experiments on three publicly available datasets of real scenarios (UCSD Ped1, UCSD Ped2 and CUHK Avenue). The experimental results show that compared with the baseline model, the accuracy of our model improved by 1.9%, 1.4% and 6.6%, respectively, across the three datasets. Compared with many popular models, the validity of our model in anomaly detection is verified.
Complexity Factor of Static Axial Complex Structures in f(R, T) Gravity
Authors: Yousaf Z. , Bhatti M. Z. , Farwa U.
Published: February 2023

This article investigates the physical features of static axial sources that produce complexity within the matter configuration within the perspective of f(R, T) theory, where R is the curvature invariant and T identifies the trace of matter energy tensor. In this case, the contracted Bianchi identities of effective as well as normal matter are used to develop the conservation equations. We split the curvature tensor to compute structure scalars, involving the physical aspects of the source in the influence of modified factors. We explore the evolving source and compute the complexity of the system. Three complexity factors are determined by using structure scalars; after that, the corresponding propagation equations are explored to investigate the intense gravitational consequences. Finally, the outcomes of irregular anisotropic spheroids are presented using the criterion of vanishing complexity. The f(R, T) corrections are shown to be an additional source of complexity for the axial anisotropic configuration.

First Identification of Amphidinols from Mexican Strains and New Analogs
Authors: Durán-Riveroll Lorena M. , Weber Jannik , Krock Bernd
Published: February 2023

The genus Amphidinium has been the subject of recent attention due to the production of polyketide metabolites. Some of these compounds have shown significant bioactivities and could be related to species interactions in the natural benthic microenvironment. Among these compounds, amphidinols (AMs) are suspected to be related to fish kills and probably implicated in ciguatera symptoms associated with the occurrence of benthic harmful algal blooms (bHABs). Here, we present the first report of a variety of AMs produced by cultured strains from several species from the Mexican Pacific, the Gulf of California, and the Gulf of Mexico. Through ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS), ten previously known AMs (AM02, -04, -05, -06, -07, -09, -11, -14, -15, and -17), four recently reported AMs (N7, N8/N9, N12, and N13), and three new variants (U1, U2, and U3) were identified. Of the twelve analyzed Amphidinium cultures, five were not AM producers, and the cell quotas of the remaining seven strains ranged from close to nondetectable to a maximum of 1694 fg cell−1, with many intermediate levels in between. The cultures from the Mexican North Pacific coast produced AMs in a higher quantity and variety than those from worldwide locations. This is the first study of AMs from Mexican Amphidinium strains, and our results confirm the relevance of continuing the investigation of the genus bioactive metabolites.

Published: February 2023

Glioblastoma is the most aggressive form of malignant brain tumor. Standard treatment protocols and traditional immunotherapy are poorly effective as they do not significantly increase the long-term survival of glioblastoma patients. Oncolytic viruses (OVs) may be an effective alternative approach. Combining OVs with some modern treatment options may also provide significant benefits for glioblastoma patients. Here we review virotherapy for glioblastomas and describe several OVs and their combination with other therapies. The personalized use of OVs and their combination with other treatment options would become a significant area of research aiming to develop the most effective treatment regimens for glioblastomas.

Published: February 2023

Pregnant women are at higher risk of severe Coronavirus disease 2019 (COVID-19) complications than non-pregnant women. The initial exclusion of pregnant women from anti-SARS-CoV-2 vaccines clinical trials has caused a lack of conclusive data about safety and efficacy for this vulnerable population. This cross-sectional study aims to define the factors related to vaccination adherence in a sample of women experiencing high-risk pregnancies. The recruited women completed a questionnaire based on the Health Belief Model. Data were analyzed to evaluate the associations between socio-demographic variables and vaccination acceptance through descriptive, univariate and multivariate logistic analyses. Among the 233 women enrolled, 65.2% (n = 152) declared that they would accept the anti-SARS-CoV-2 vaccine. Multivariate analysis showed that vaccination acceptance was associated with a high educational level (aOR = 4.52, p = 0.001), a low perception of barriers to vaccination (aOR = 1.58, p = 0.005) and the gynecologist’s advice (aOR = 3.18, p = 0.01). About a third of pregnant women are still hesitant about the anti-SARS-CoV-2 vaccine, probably because of the conflicting information received from media, friends, acquaintances and health institutions. Determining factors linked to vaccine hesitancy among pregnant women is useful for creating vaccination strategies that increase vaccination uptake.

Transgender women (TGW) in India, especially those who engage in sex work, are at high risk for HIV. Guided by the information-motivation-behavioral skills model and qualitative formative research findings, Sakhi (girlfriend), a 3-week smartphone-based pilot intervention consisting of short videos (one/week) and text messages (two/week), was implemented using a one-group pre- and post-test design to test its efficacy in promoting condom use and HIV testing among TGW (n = 50) who engage in sex work in Chennai. Changes in outcomes were assessed by conducting multivariable analyses using generalized estimating equations. Participants’ mean age was 26 years, and the mean monthly income was INR 21700 (USD 292). About one-third completed college, and 96% were HIV-negative. Significant changes in the desired direction were observed in the primary outcomes: condom use – decrease in the engagement of condomless anal sex with male partners (12% to 2%, p < 0.05) and HIV testing – increase in intentions to undergo HIV testing every 6 months (34% to 86%, p < 0.001); and in some of the secondary outcomes: decrease in alcohol use before sex, increase in intentions to use condoms consistently and increase in the well-being score. This study demonstrated the feasibility, acceptability, and preliminary efficacy of the Sakhi intervention and warrants a larger randomized trial among diverse subgroups in diverse settings.
Development of a Distributed Control System for the Hydrodynamic Processes of Aquifers, Taking into Account Stochastic Disturbing Factors
Authors: Ilyushin Yury Valeryevich , Asadulagi Mir-Amal Mirrashidovich
Published: February 2023

Uncontrolled, intensive extraction of water from mineral water deposits can lead to negative consequences, the penetration of sewage beyond the water-resistant layers, the destruction of the structure of aquifers and the further loss of the mineral water source. This paper deals with the issues of control of hydrodynamic processes under random impacts in the aquifers of mineral water deposits using mathematical models. The analysis of the technological process of mineral water extraction and statistical analysis of retrospective monitoring data of the deposit were carried out in order to confirm the hypothesis of the stationarity of the processes under consideration. A mathematical model of hydrogeological processes occurring under random disturbances has been constructed. The influence of such disturbances is expressed in deviations of the head in the aquifer from the desired value. Controlling consists of maintaining the head of aquifers at a given level in order to preserve the hydro-mineral base of the region. Lumped and distributed controllers are proposed as corrective blocks, the parameters of which are calculated by frequency methods of controller synthesis. The use of a closed loop control system minimizes the influence of random effects.
Barriers to Innovation in Water Treatment
Authors: Ahmed Farah , Johnson Daniel , Hashaikeh Raed , Hilal Nidal
Published: February 2023

While phenomenal strides are being made on the technological front, the water industry lags behind other sectors in the adoption of innovative techniques. Contributing factors include long lifetimes and costs of previous water infrastructure, risk aversion due to public health concerns surrounding water access, and low financing for innovation. While many professionals see the need for innovation, they prefer traditional tried and tested routes. Regulations may be useful in accelerating the transition to sustainable technologies. Furthermore, the literature emphasizes the role of environmental, social, and political actors, as well as their interplay in realizing innovation in the water sector.

Published: February 2023

Although healthy ecosystems are vital to sustaining human society, the Brazilian Cerrado and Atlantic Forest biomes have suffered from disorderly human development and the intense use of natural resources. Thus, cost-effective studies are needed to develop tools to assess environmental conservation and the integrity of water courses to inform decisions for ensuring their recovery where ecosystem maintenance is deficient. This study sought to develop a methodology in which the Watershed Habitat Evaluation and Biotic Integrity Protocol (WHEBIP) and Rapid Assessment Protocol for Habitat Diversity (RAP) could be used in an integrated, adaptive manner to evaluate the Water Ecosystem Integrity (WEI) in courses of rivers and streams in tropical regions of the Brazilian Cerrado–Atlantic Forest interface undergoing intense agricultural exploitation. Accordingly, a spatial assessment using geographic information systems was followed by a field visit to apply the methodology. A preliminary assessment of the soil conditions in the Lobo Reservoir Hydrographic Basin was conducted, identifying stretches of rivers and streams that were suitable for payment for environmental services and for recovery from the impact of anthropic activities. Such activities were present in 50.23% of the basin’s total area, and intensive degradation was found in stretches of the water courses, primarily where the head springs of the Itaqueri River and Lobo Stream, the principal tributaries of the Lobo Reservoir, lie. Native vegetation, Brazilian Cerrado, and reforestation occupy a total of 38.5% of the basin, comprising areas of intense conservation activity by the Brazilian government.

Assessing how land use change will affect water production ecosystem services is essential to developing sound water resource management and ecosystem conservation. The results of a coordination analysis of land-use intensity and water yield based on future land-use simulation projections are useful for future land-use planning. To effectively assess water production rates, the PLUS and InVEST models were used to dynamically assess the changes in water production occurring in the urban agglomeration on the northern slopes of the Tianshan Mountains from 2000 to 2030 under different scenarios of land-use change. The results show that the water-production rates in the study area from 2000 to 2020 were 517.26 × 106 m3, 582.28 × 106 m3, and 456 × 106 m3, showing an increasing and then decreasing trend, with the water production function decreasing from the foothills of the Tianshan Mountains to the north and south, with values of 509.10 × 106 m33, 510.90 × 106 m3, and 502.28 × 106 m3 being presented for the three scenarios in 2030. The rapid economic development scenario presents the lowest water yield values and the ecological conservation development scenario presents the highest water yield values. Changes in water production rates are closely related to changes in land use, which can be verified further by an analysis of the coordination between land- use intensity and water production. For this study area, the ecological conservation development scenario may be more in line with the future urban development pattern, and the results of the present study can provide some scientific references for land-use planning.
Effect of Sand Co-Presence on CrVI Removal in Fe0-H2O System
Authors: Gheju Marius , Balcu Ionel
Published: February 2023

The aim of the present study was to provide new knowledge regarding the effect of non-expansive inert material addition on anionic pollutant removal efficiency in Fe0-H2O system. Non-disturbed batch experiments and continuous-flow-through column tests were conducted using CrVI as a redox–active contaminant in three different systems: “Fe0 + sand”, “Fe0 only” and ”sand only”. Both experimental procedures have the advantage that formation of (hydr)oxide layers on Fe0 is not altered, which makes them appropriate proxies for real Fe0-based filter technologies. Batch experiments carried out at pH 6.5 showed a slight improvement of CrVI removal in a 20% Fe0 system, compared to 50, 80 and 100% Fe0 systems. Column tests conducted at pH 6.5 supported results of batch experiments, revealing highest CrVI removal efficiencies for “Fe0 + sand” systems with lowest Fe0 ratio. However, the positive effect of sand co-presence decreases with increasing pH from 6.5 to 7.1. Scanning electron microscopy—energy dispersive angle X-ray spectrometry and X-ray diffraction spectroscopy employed for the characterization of Fe0 before and after experiments indicated that the higher the volumetric ratio of sand in “Fe0 + sand” system, the more intense the corrosion processes affecting the Fe0 grains. Results presented herein indicate the capacity of sand at sustaining the efficiency of CrVI removal in Fe0-H2O system. The outcomes of the present study suggest that a volumetric ratio Fe0:sand = 1:3 could assure not only the long-term permeability of Fe0-based filters, but also enhanced removal efficiency of CrVI from contaminated water.

Authors: GÜLSEVEN SIDIR Yadigar , SIDIR İsa
Published: February 2023

The electronic, hydrophobic and global reactivity parameters of modeled 28 different 5,8-quinolinequinone derivatives have been calculated using DFT (B3LYP)/6-31G(d,p) method and basis set. The molecular descriptors are chosen molecular polarizability, dipole moment, frontier molecular orbital energy, molecular volume, ionization potential, electron affinity, electronegativity, molecular hardness, molecular softness, electrophilic index, molar refractivity, octanol–water partition coefficient, entropy and capacity of heat. The relations between molecular descriptors have been investigated dependent on their correlations. QSAR/QSPR models have been derived for anti-proliferative and anti-inflammatory activity of these 5, 8-quinolinequinone (s) derivatives. The dependence of the electronegativity parameter on both electronic and thermochemical parameters is found to be the best correlated parameter.

At a global level, rivers serve as receptors for large amounts of waste generated by human activities such as agriculture, industrial activity and domestic activities, on the other hand, they are an important source of water supply for both agricultural, industrial and domestic. Therefore, in recent years, receptors have been affected by pollutants, in the case of Contamination by fats and oils is a problem caused by activities such as: the existence of outboard motor repair shops, boat landings, discharges of water from houses-rooms, gas stations, public markets, yards, among others. The effects of these pollutants affect the public health of the population living outside the Grijalva basin, with the respiratory and skin conditions when in direct contact with these chemicals, even causing various types of cancer. For all of the above, the development of this research project was motivated, which will allow knowing the levels of contamination of fats and oils in the years 2019 and 2020 in the study area, being Arroyo Polo 1st and 3rd sections of Frontera, Centla, Tabasco, based on the comparison of the maximum permissible limits (LMP) of the NOM-001-SEMARNAT-1996. To evaluate the behavior and projection of the data, the Minitab version 18 software was used, where the analyzed data of the years 2019 and 2020 were taken to be able to indicate if there is a significant increase in later years. A trend towards an increase in contaminating fats and oils was observed. In the first sampling, the average concentrations of fats and oil were 5.23 mg/L. In the second sampling, the concentration of fats and oils was the lowest of 5.02 mg/L and the highest concentration was 6.23 mg/L. of the third and fifth sampling point, it is observed in both cases that there is a tendency towards an increase in contaminants. At the fourth sampling point, It is observed that there is a tendency towards the decrease of this contaminant. In both samples, the concentrations of fats and oils are below what is established by NOM-001-SEMARNAT-1996, since said norm establishes the maximum permissible limit of 25 mg/L per month.

Muslim Intellectual History
Authors: Pervez Saulat
Published: February 2023

This article strives to chart the intellectual history of Muslims and the trans-civilizational, discursive tradition of Islam spanning fourteen centuries. It chronicles the scholarly projects shaping Islamic thought as they developed in the wake of the Prophet’s (s) death and intensified in the ensuing centuries despite the numerous changes and tumultuous times the Muslim ummah encountered. Together with an accompanying map and visual timeline, it endeavors to empower students of Islam in general and Islamic Studies programs in particular with an appreciation of the breadth and depth of Muslim intellectual history. The article begins by tracing the foundation of early regional centers, the side-by-side formation of disciplines, the development of the various legal schools as well as the many strains of Islamic thought, and how they not only influenced one another but also became absorbed into mainstream Islam, ending with an overview of the impact of modernity on Islamic thought. Through this effort, I hope that students will be able to cultivate a rudimentary understanding of Islamic scholarship in its historical context, make interdisciplinary connections, critically engage with the individual disciplines in their focused study, and gain an overall nuanced reverence for the collective Muslim intellectual legacy across 1400 years along with the diversified scholarly struggles to diligently honor and observe the message received from the Prophet Muhammad (s). The map and timeline accompanying the present survey of Muslim intellectual history are available here.
IRON HOMEOSTASIS IN THE SUBJECTS WITH IMPAIRED GLUCOSE TOLERANCE

Diabetes is common. Globally, diabetes has increased. Changes in iron metabolism markers, such as transferrin and ferritin, may induce or
exacerbate type 2 diabetes. Several iron metabolism indicators independently predict reduced glucose tolerance, type 2 diabetes, and chronic
glycemic characteristics. Ferritin and transferrin levels have increased with IGT and T2DM prevalence. Rising ferritin levels are likely due to
increased iron reserves, but the association between transferrin and diabetes seems unrelated to iron storage, inammation, or lipid metabolism.

studied. The glomeruli cannot lter the large, negatively charged serum transferrin molecule. Thus, urine transferrin levels may indicate diabetic
nephropathy development. Iron levels should be examined in Type 2 diabetics since too much might aggravate the illness.

Villa Borbone show up to the eye of the attentive traveler immersed in the geometries of a lush garden, fading into the motility of the coastal landscape. A set of buildings, including the small chapel steeped in classical suggestions, is a part of what once constituted the vast property of the ducal family. An incredibly precious heritage, which this book aims to account for, restoring its history, its materiality, but also all its fragility, in an attempt to define a path that can contribute to its preservation.

Neste capítulo, temos como objetivo principal apresentar e problematizar questões relacionadas à decolonialidade no ensino superior que vêm sendo pesquisadas por meio de metodologias qualitativas na Universidade Federal da Bahia. A partir da constatação de que o conhecimento acadêmico-científico no Brasil apresenta um forte traço da colonialidade, torna-se urgente enunciar os processos que têm tornado a Universidade um espaço estratégico para o processo de decolonização. Reconhecemos os avanços nos últimos anos com a emergência de demandas pela publicação de políticas e programas, bem como pela reconfiguração do currículo das disciplinas para atender à diversidade observada na universidade. No entanto, não obstante os avanços observados, ainda podemos notar uma ascendência colonial em modos de pensar a produção de conhecimento e as estratégias didáticas de seu compartilhamento, sobretudo, em época de busca de parâmetros alinhados a epistemologias do Norte Global, em especial, o Eurocentrismo. Neste capítulo, apresentaremos três pesquisas nas quais a decolonização é uma temática transversal. Além disso, destacamos que estas pesquisas se desenvolveram com o aporte metodológico qualitativo, o qual se revela importante para a obtenção de resultados teóricos e práticos.

Bimbingan dan konseling di Indonesia telah resmi masuk sejak 1975. Namun, dalam praktiknya bimbingan konseling kerap mengalami kendala, sehingga eksistensinya cendrung bernada negatif. Hal tersebut disebabkan oleh beberapa faktor, yaitu keterbatasan kualitas sumber daya manusia dalam bidang bimbingan dan konseling. Karenanya, dalam implementasinya layanan konseling di sekolah kurang efektif. Model konseling KIPAS hadir menjadi tawaran alternatif terhadap problematik tersebut. Konsepsi KIPAS menawarkan posisi diri sebagai syarat kualitas upaya meminimalisir nada negatif terhadap bimbingan dan konseling. KIPAS yang merupakan akronim (posisi diri) dari (1) kawan, (2) inovator, (3) pamong, (4) abdi, dan (5) supporter. Dalam implementasinya, langkah model KIPAS yaitu, (1) kabar gembira; (2) integrasi dan internalisasi; (3) perencanaan tindakan; (4) aktualisasi; dan (5) sertifikasi. Hal ini menunjukkan bahwa konsepsi konseling KIPAS memang dipersiapkan untuk menjadi tawaran mencerahkan bagi ketimpangan pelaksanan bimbingan konseling selama ini. Melalui konsepsi ini, diharapkan terciptanya suasana baru yang lebih menggembirakan dan mengubah stigma konseling ke arah yang lebih baik.

Наголошено про пріоритетне значення на підприємствах мотивації праці через задоволення потреб персоналу. Виділено результати останніх досліджень і публікацій вітчизняних науковців, які доводять важливість врахування низки чинників при організації та удосконаленні мотивації праці. Сформовано структуру взаємозв’язків основних категорій мотивації праці персоналу підприємства, що корелюються з їхніми потребами та очікуваними результатами від її удосконалення. Виділено низку груп стимулів, які активно використовуються підприємствами при забезпеченні мотивації праці. При цьому більшість із них набувають матеріальної та нематеріальної форми. Виділено пріоритетне значення способів нематеріального стимулювання праці, які розділено на соціальні, моральні, творчі, психологічні. Наголошено на позитивних та негативних наслідках мотивації праці, які головним чином визначаються інтересами персоналу. Відповідно до таких висновків розділено інтереси персоналу на індивідуальні, колективні та суспільні. Доведено пріоритетне значення індивідуальних інтересів, а відтак і таких стимулів при удосконаленні мотивації праці. Запропоновано систему потреб персоналу підприємства розділяти на сукупні (враховують загальну сукупність основних стимулів та мотивів) та вторинні (визначають соціальні потреби, потреби в повазі, самовиявлення) потреби. Зроблено висновки, що в основу діалектичної єдності матеріальних і нематеріальних стимулів необхідно закладати взаємозв’язки між різними групами потреб та інтересів. Наголошено на пріоритетах органів державного управління при наданні допомоги (організаційної, інституційної, економічної та іншої) підприємствам при удосконаленні мотивації праці. Доведено необхідність для підприємств у контексті мотивації праці досягнення певного соціального ефекту, що дозволяє відповідно до світового досвіду суттєво підвищити продуктивність та ефективність праці. Значну частину дослідження приділено проблемам соціальної відповідальності підприємства, через яку можливе вирішення низки стратегічних завдань, як забезпечення ефективності мотивації праці, так і покращення ділової активності, партнерських відносин, результатів діяльності підприємства.
ОБЛІКОВЕ ЗАБЕЗПЕЧЕННЯ СИСТЕМИ УПРАВЛІННЯ ОСНОВНИМИ ЗАСОБАМИ ПІДПРИЄМСТВА: ОРГАНІЗАЦІЙНИЙ АСПЕКТ

У статті проаналізовано поняття обліку основних засобів на підприємстві. Обґрунтовано різні точки зору стосовно трактування сутності поняття “основні засоби”, одним із яких є “основні засоби – засоби виробництва, які беруть участь у виробничому процесі багато разів, не змінюючи натуральної форми, виконуючи одну й ту ж саму функцію протягом декількох виробничих циклів та переносять свою вартість на створений продукт частинами”. Також зазначено трактування даного терміна відповідно до статті 14 Податкового кодексу України. Визначено основні завдання з організації обліку основних засобів. Теоретичні та практичні дослідження процесу експлуатації основних засобів дали можливість виокремити його інформаційні потоки, котрі підлягають документуванню та знаходять своє відображення в системі рахунків бухгалтерського обліку. У статті зображено модель інформаційних потоків у процесі документування операцій із експлуатації (використання) основних засобів. Виходячи з побудованої моделі інформаційних потоків, процес експлуатації основних засобів доцільно розглядати як сукупність організаційних дій щодо ступеня використання об’єктів у господарській діяльності підприємства, які можна згрупувати в активну та пасивну форми. Також перелічено рекомендовані документи, які доцільно було б затверджувати кожен рік. Вказано, що організацію обліку основних засобів потрібно будувати з урахуванням таких основних факторів: довготривалого терміну використання об’єктів, протягом якого їх необхідно обліковувати; технічно складної та багатокомпонентної будови, котру необхідно детально відображати в облікових регістрах; необхідність проведення ремонтів, реконструкції, модернізації основних засобів призводить до зміни їх первісних характеристик, котрі потрібно своєчасно відображати у регістрах обліку; коштовність об’єктів вимагає адекватної організації процесів їх приймання, списання, а також обліку наявності, які б забезпечували їхню цілісність та збереження у робочому стані. Звернено увагу на те, що основними шляхами вдосконалення організації обліку основних засобів є раціоналізація кожної форми документів і регістрів обліку, методів збору, обробки та узагальнення облікової інформації, адаптованих до сучасних умов.
