Published: October 2023

In recent years, the frequent outbreaks of Ulva prolifera in the South Yellow Sea have become the largest-scale green tide disasters in the world. The causes of its outbreaks have garnered widespread attention, particularly the coupled effects of multiple factors. Leveraging the Google Earth Engine (GEE) platform, this study conducted a long-term investigation of the Yellow Sea green tide disaster and the factors using multi-source satellite imagery. Finally, the combined effects of natural environmental changes and human activities on Ulva prolifera were analyzed by redundancy analysis (RDA) and variation partitioning analysis (VPA). The results indicate: (1) Since 2018, the scale of Ulva prolifera in the South Yellow Sea has shown a distinct “biennial” trend. (2) Regarding environmental factors, SST, PAR, precipitation, and windspeed have certain effects on the growth of Ulva prolifera. However, they cannot be considered as determining factors for the outbreak of Ulva prolifera (0.002 < R2 < 0.14). Regarding anthropogenic factors, the recycle time of Pyropia yezoensis culture rafts has a relatively minor influence on the extent of Ulva prolifera. There exists a certain positive correlation (R2 = 0.45) between the human footprint index (HFI) of Jiangsu Province and the annual variation in Ulva prolifera area in the South Yellow Sea. (3) The combined effects of multiple factors influence green tide outbreaks. The Ulvatotal explanatory power of SST, PAR, precipitation, windspeed, HFI, and the recycle time of Pyropia yezoensis culture rafts for the annual variation in the Ulva prolifera area is 31.8%, with these factors interweaving and mutually influencing each other. This study offers important insights into quantifying the driving forces behind Ulva prolifera in the South Yellow Sea, providing valuable information for a deeper comprehension of the complexity of marine ecosystems and sustainable management.
Exploring the Nuances of Emirati Identity: A Study of Dual Identities and Hybridity in the Post-Oil United Arab Emirates
Authors: Al Hameli Asmaa , Arnuco Monerica
Published: October 2023

In the face of globalization and diversity in the United Arab Emirates, the post-oil generation of Emiratis face unique challenges in navigating their cultural and national identities. Previously published research and scholarly works have engaged in complex discourse around Emirati identities, describing them as a population with similar genealogical backgrounds, ancestry, history, and cultural values. However, the element of heterogeneity among Emiratis remains highly under-examined. This research paper will examine the experiences of Emiratis with dual identities in the UAE, investigating their perceptions, attitudes, and narratives on being labeled as the “other” by their compatriots; exploring the spaces where hybrid Emiratis, locally known as “halfies”, choose to reveal and conceal their multiplicity. In order to examine this complex socio-cultural phenomenon, semi-structured interviews with twenty Emiratis with twin identities were employed for this empirical study. The examination of the interviews uncovered the difficulties that individuals with mixed heritage encounter, as well as their strategies for overcoming these obstacles in order to find acceptance in a society that values a shared national identity. The research findings contribute to the scholarship of Emirati identity construction.

Authors: Dumont Mélody , Gomez Christopher , Arnaud-Fassetta Gilles , Lissak Candide , Viel Vincent
Published: October 2023

On 5–6 July 2017, an unstable atmospheric condition caused an unusual concentration of rainfall above the Northern part of Kyushu Island, triggering a set of hydro-meteorological hazards. Within the affected area, the mountainous subwatershed of the Akatani River was significantly impacted by numerous landslides combined with debris flow and floods. National and local agencies deployed a plan of reconstruction to restore the floodplain and protect inhabitants. Regarding the hydrosystem in the Akatani watershed, this reconstruction project mainly focuses on the restoration of damaged protection systems and the construction of new infrastructures. Thus, this paper aims to explain the restoration plan of the Akatani River in terms of the strategic Japanese River System Sabo and then as a model of a national-scale spatial plan. It draws on (i) a literature review based on the historical evolution of Japanese protection systems and the River Sabo System; (ii) field surveys in 2019, 2022 and 2023, in conjunction with (iii) interviews with local, regional, and national officials; and (iv) a Geographical Information System analysis of previously and newly built protection systems through aerial photograph interpretation and geospatial data. Sabo works implemented in the Akatani watershed illustrate the engineering vision of Japanese river management. They also constitute a comprehensive system and include a downstream–upstream logic which echoes that of the River System Sabo. In addition, the disaster of July 2017 and the government’s response emphasize the continuous adaptation and improvement of the Japanese disaster management system, which mitigates severe disasters.

Published: October 2023

This quantitative research study delves into the adoption of management accounting tools (MATs) and their impact on organizational performance and sustainability within the provincial branches of the Supreme Audit Agency of the Republic of Indonesia (Badan Pemeriksa Keuangan Republik Indonesia/BPK-RI). A well-structured research design and data collection approach is employed, where surveys are administered to 435 senior auditors within BPK-RI provincial branches. A robust data analysis using structural equation modeling (SEM) through SmartPLS v4 software is conducted to assess the relationships between variables. This study provides compelling evidence that the perceived usefulness of MATs significantly impacts their adoption. This underscores the importance of how users perceive the utility of these tools. Furthermore, this research identifies that MATs’ adoption directly affects organizational performance and sustainability, highlighting the positive impact of these tools in the public sector. However, this research suggests that user perceptions of the ease of use of MATs do not significantly influence their adoption in the public sector accounting context. The study also reveals that MATs play a mediating role, facilitating the relationship between perceived ease of use and perceived usefulness and their subsequent impact on organizational performance and sustainability. These findings are valuable for public sector organizations, policy development, and future research initiatives, contributing to a better understanding of MATs’ adoption and its implications in the dynamic landscape of public sector accounting, especially in Indonesia.
Does Emotional Labor Trigger Turnover Intention? The Moderating Effect of Fear of COVID-19
Authors: Zhu Tingting , Park Sung Kyu , Tu Ruonan , Ding Yi
Published: October 2023

Turnover is a costly and time-consuming expense, especially for service industry businesses. To date, little is known about whether and how emotional labor may activate employee turnover intention in the service industry. In order to solve the above problems and fill the gaps, this study aimed to verify how emotional labor can trigger turnover intention during the COVID-19 pandemic. Based on job characteristics theory and job demands–resources theory, this study examined whether emotional display rules and emotional labor strategies affect turnover intention brought on by emotional exhaustion and job dissatisfaction, with fear of COVID-19 as a moderator. After testing our hypotheses using a sample of 623 individuals from China’s service industry, this study found that emotional display rules (positive and negative display rules) are significantly related to emotional labor strategies (deep acting, expression of naturally felt emotions, and surface acting). In particular, positive display rules have a positive impact on deep acting and the expression of naturally felt emotions and are more closely related to the expression of naturally felt emotions. Negative display rules negatively affect surface acting. Moreover, emotional labor strategies correlate significantly with emotional exhaustion, job satisfaction/dissatisfaction, and subsequent turnover intention. Thus, deep acting and the expression of naturally felt emotions are related to low emotional exhaustion and high job satisfaction, while surface acting is related to high emotional exhaustion and low job satisfaction. Emotional exhaustion has a negative effect on job satisfaction and a positive effect on turnover intention. Job satisfaction significantly weakens turnover intention. In addition, fear of COVID-19 has a moderating effect on the relationship between job satisfaction and turnover intention. The group with a high fear of COVID-19 has higher turnover intention even in job satisfaction situations than the group with a low fear of COVID-19. This work advances emotional labor research by combining two dimensions of emotional display rules and three dimensions of emotional labor strategies into a framework, investigating the mechanism through which emotional labor influences turnover intention, and revealing the moderating effect of fear of COVID-19 in the process.

Published: October 2023

Rural economies are crucial for global development, with more than 80% of the world’s population living in rural areas and agriculture providing livelihoods for approximately 2.5 billion people worldwide. However, these economies are often vulnerable to various factors, including climate change, natural disasters, and a lack of progressive economic policies. The main aim of making rural economies more sustainable is to promote long-term economic development, protect the environment, and improve the quality of life in urban–rural communities. This paper explored certain strategies for enhancing rural economies to be more sustainable. The results show that smart growth has been rapidly growing in urban cities, while certain communities outside urban areas have been left behind. However, both urban and rural communities need economic growth and be adaptive to smart growth to serve their communities and adhere to the Sustainable Development Goals (SDGs) in the new era of innovation. Thus, we argue that rural areas are a big part of emerging economies. As such, they cannot be left behind in any smart growth. In this study, we found that rural economies need training and up-skilling in order to improve their sustainability and efficiency targets. Through a systematic review, this paper looked at various ways rural communities can solve their challenges toward smart growth and the sustainability of their resources. As a result, we propose solutions for urban–rural communities to implement in daily activities in terms of policy and practice approaches.
A Harmful Algal Bloom Detection Model Combining Moderate Resolution Imaging Spectroradiometer Multi-Factor and Meteorological Heterogeneous Data
Authors: Bu Xiangfeng , Liu Kai , Liu Jingyu , Ding Yunhong
Published: October 2023

Over the past few decades, harmful algal blooms (HABs) have occurred frequently worldwide. The application of harmful algal bloom detection when based solely on water quality measurements proves challenging in achieving broad generalization across various regions. Satellite remote sensing, due to its low risk, cost effectiveness, and wide ground-coverage capabilities, has been extensively employed in HAB detection tasks. However, relying solely on remote sensing data poses issues of false positives, false negatives, and the incomplete consideration of contributing factors in HAB detection. This study proposes a model for harmful algal bloom detection by integrating MODIS multifactor data with heterogeneous meteorological data. Initially, a dataset named MODIS_MI_HABs is constructed by gathering information from 192 instances of harmful algal bloom events worldwide. Subsequently, remote sensing data corresponding to specific regions are collected; all were obtained from a moderate resolution imaging spectroradiometer (MODIS) aboard an ocean-color-detecting satellite. This dataset encompasses variables such as chlorophyll-a concentration, the sea surface temperature, photosynthetically active radiation, the relative radiation stability differences, the six seawater-absorption coefficients, and three scattering coefficients. By fusing six meteorological factors, latitude and longitude information, and remote sensing data, a regression dataset for harmful algal bloom detection is established. Finally, employing harmful algal bloom cell concentration as the data label, seven machine learning models are employed to establish correlations between the remote sensing data, heterogeneous meteorological data, and harmful algal bloom cell concentrations. The root mean square error (RMSE), mean absolute error (MAE), explained variance (EV), and coefficient of determination (R2) parameters are used to evaluate the regression performance. The results indicate that the extreme gradient boosting (XGR) model demonstrates the best predictive capability for harmful algal blooms (leave-one-out: RMSE/MAE = 0.0714). The XGR model, trained with the entire dataset, yields the optimal predictive performance (RMSE = 0.0236, MAE = 0.0151, EV = 0.9593, R2 = 0.9493). When compared to the predictions based on the fixed-area water quality analysis and single-source remote sensing data usage, the proposed approach in this paper displays wide applicability, offering valuable support for the sustainable development of marine ecology.
Solitary Wave Propagation of the Generalized Rosenau–Kawahara–RLW Equation in Shallow Water Theory with Surface Tension
Authors: AL-saedi Akeel , Nikan Omid , Avazzadeh Zakieh , Lopes António
Published: October 2023

This paper addresses a numerical approach for computing the solitary wave solutions of the generalized Rosenau–Kawahara–RLW model established by coupling the generalized Rosenau–Kawahara and Rosenau–RLW equations. The solution of this model is accomplished by using the finite difference approach and the upwind local radial basis functions-finite difference. Firstly, the PDE is transformed into a nonlinear ODEs system by means of the radial kernels. Secondly, a high-order ODE solver is implemented for discretizing the system of nonlinear ODEs. The main advantage of this technique is its lack of need for linearization. The global collocation techniques impose a significant computational cost, which arises from calculating the dense system of algebraic equations. The proposed technique estimates differential operators on every stencil. As a result, it produces sparse differentiation matrices and reduces the computational burden. Numerical experiments indicate that the method is precise and efficient for long-time simulation.
High-Riding Conus Medullaris Syndrome: A Case Report and Literature Review—Its Comparison with Cauda Equina Syndrome
Authors: Huang Ya-Lin , Chang Shin-Tsu
Published: October 2023

Introduction: Conus medullaris syndrome (CMS) is a distinctive spinal cord injury (SCI), which presents with varying degrees of upper motor neuron signs (UMNS) and lower motor neuron signs (LMNS). Herein, we present a case with a burst fracture injury at the proximal Conus Medullaris (CM). Case Presentation: A 48-year-old Taiwanese male presenting with lower back pain and paraparesis was having difficulty standing independently after a traumatic fall. An Imaging survey showed an incomplete D burst fracture of the T12 vertebra. Posterior decompression surgery was subsequently performed. However, spasticity and back pain persisted for four months after surgical intervention. Follow-up imaging with single photon emission computed tomography (SPECT) and a whole body bone scan both showed an increased uptake in the T12 vertebra. Conclusion: The high-riding injury site for CMS is related to a more exclusive clinical representation of UMNS. Our case’s persistent UMNS and scintigraphy findings during follow-up showcase the prolonged recovery period of a UMN injury. In conclusion, our study provides a different perspective on approaching follow-up for CM injuries, namely using scientigraphy techniques to confirm localization of persistent injury during the course of post-operative rehabilitation. Furthermore, we also offered a new technique for analyzing the location of lumbosacral injuries, and that is to measure the location of the injury relative to the tip of the CM. This, along with clinical neurological examination, assesses the extent to which the UMN is involved in patients with CMS, and is possibly a notable predictive tool for clinicians for the regeneration time frame and functional outcome of patients with lumbosacral injuries in the future.

Published: October 2023

In search of physics beyond the standard model, new phenomena can be relevant in low energies. In view of the Standard Model Extension is an effective field theory, in this study we explore the fermionic sector by showing that the properties of nonrelativistic quantum systems can be modified. We study one-dimensional nonrelativistic quantum systems under Lorentz symmetry violation effects caused by the coupling between the fixed vector field fμγ5 and the derivative of the fermionic field. We deal with the quantum bouncer, the attractive inverse-square potential, a modified attractive inverse-square potential, and a scalar exponential potential inside this scenario of the Lorentz symmetry violation. Then, we show that the spectra of energy are influenced by the Lorentz symmetry violation effects.

Nasopharyngeal cancer (NPC) is a prevalent type of cancer that often takes the form of undifferentiated carcinoma in the Maghreb region. It affects people of all ages. NPC diagnosis, mainly based on detecting Epstein-Barr virus (EBV), has not been well evaluated in North Africa. We compared the classical EBV serological tests using indirect immunofluorescence to the detection of EBV DNase antibodies by immunoblot in Algerian NPC patients. Significant variations were observed among different age groups of patients regarding the presence of VCA-IgA antibodies (0–14 and ≥30 years old, p < 0.0001; 15–19 and ≥30 years old, p < 0.01) and EA-IgA (0–14 and ≥30 years old, p < 0.01; 15–29 and ≥30 years old, p < 0.05). Differences were also noted in the titers of IgA anti-VCA and anti-EA antibodies across the three age groups. Some patients under the age of 30 with detectable IgG anti-VCA antibodies had undetectable IgA anti-VCA antibodies. These patients had a strong anti-DNase IgA response. However, older individuals had a higher level of anti-DNase IgG. Before treatment, children had strong DNase reactivity as indicated by specific IgA antibodies. Young adults had high IgA anti-DNase response, but the elderly (90.9%) had a lower response for these antibodies. Following therapy, the children retained high levels of IgA anti-DNase antibodies, and 66% of the young adults demonstrated robust antibody reactivity against DNase. In contrast, IgG responses to anti-DNase were low in children. This study demonstrated the utility of anti-DNase responses in the diagnosis and prognosis of NPC.

Human immunodeficiency virus type 2 (HIV-2) is known to be less pathogenic than HIV-1. However, the mechanism(s) underlying the decreased HIV-2 pathogenicity is not fully understood. Herein, we report that β-chemokine CCL2 expression was increased in HIV-1-infected human monocyte-derived macrophages (MDM) but decreased in HIV-2-infected MDM when compared to uninfected MDM. Inhibition of CCL2 expression following HIV-2 infection occurred at both protein and mRNA levels. By microarray analysis, quantitative PCR, and Western blotting, we identified that Signal Transducer and Activator of Transcription 1 (STAT1), a critical transcription factor for inducing CCL2 gene expression, was also reduced in HIV-2-infected MDM. Blockade of STAT1 in HIV-infected MDM using a STAT1 inhibitor significantly reduced the production of CCL2. In contrast, transduction of STAT1-expressing pseudo-retrovirus restored CCL2 production in HIV-2-infected MDM. These findings support the concept that CCL2 inhibition in HIV-2-infected MDM is meditated by reduction of STAT1. Furthermore, we showed that STAT1 reduction in HIV-2-infected MDM was regulated by the CUL2/RBX1 ubiquitin E3 ligase complex-dependent proteasome pathway. Knockdown of CUL2 or RBX1 restored the expression of STAT1 and CCL2 in HIV-2-infected MDM. Taken together, our findings suggest that differential regulation of the STAT1—CCL2 axis may be one of the mechanisms underlying the different pathogenicity observed for HIV-1 and HIV-2.
Generation of High-Resolution Gridded Runoff Product for the Republic of Korea Sub-Basins from Seasonal Merging of Global Reanalysis Datasets
Authors: Sunwoo Woo-Yeon , Nguyen Hoang Hai , Jun Kyung-Soo
Published: October 2023

Gridded runoff product at the sub-basin level is pivotal for effective hydrologic modeling and applications. Although reanalyses can overcome the lack of traditional stream gauge networks to provide reliable geospatial runoff data, the inherent uncertainties associated with single products are still a problem. This study aims to improve the single products’ limitations over the heterogeneous Republic of Korea region by merging three common global reanalysis datasets to generate a high-quality and long-term gridded runoff product at a high resolution. The merging method relies on triple collocation (TC) analysis, which requires no reference runoff dataset, with a modification that was applied separately to wet and dry seasons (seasonal merging). A comparison between the merged runoff and its parent products at 0.10° grid, on a daily basis, and using the entire 10-year period (2011–2020) against an independent ground-based sub-basin runoff product generally indicated a superior performance of the merged product even at the national scale of Republic of Korea. Moreover, a slight improvement obtained with the seasonal merging compared to the traditional all-time merging highlighted the potential of this modification to address several drawbacks in the TC assumption, especially the non-stationary runoff pattern caused by seasonal rainfall effects in the Republic of Korea. Despite the need for further improvement such as bias correction, the results of this study encourage making a reliable benchmark runoff product at a regional scale, which is beneficial for flood/drought monitoring and artificial intelligence-based hydrologic model training.
On Internal Erosion of the Pervious Foundation of Flood Protection Dikes
Authors: Girolami Laurence , Bonelli Stéphane , Valois Rémi , Chaouch Naïm , Burgat Jules
Published: October 2023

This work focuses on the mechanisms that trigger internal erosion of the pervious foundation of flood protection dikes. The origin of these permeable layers is generally attributed to the presence of a paleo-valley and paleo-channels filled with gravelly-sandy sediments beneath the river bed and dikes. These layers may extend into the protected area. Visual observations of leaks, sand boils and sinkholes in the protected area testify to internal erosion processes in the underground soil. Local geological conditions are part of the information to be sought to explain these processes: presence of permeable soils and position of interfaces. Results obtained on Agly dikes (France), using two classical geophysical methods (EMI and ERT), were analyzed using cored soils and showed that it is not enough to simply conclude to the presence of backward erosion piping. The possibility of internal erosion, such as suffusion or contact erosion, must also be considered as the cause of leaks, sand boils and sinkholes. As the results obtained are explained by the presence of a paleo-valley and paleo-channels beneath the river bed and dikes—commonly encountered in this context—the methodology presented and the results obtained are likely to be relevant for many dikes.

Published: October 2023

The Great Lakes Depression region basin is among the most sensitive regions to vegetation change due to climate change. This study estimated spatial-temporal changes and relationships in hydro-climate and vegetation dynamics in the basin. Studying the spatial-temporal variation between vegetation dynamics and hydro-climate in this basin is essential for assessing climate change and sustainability. This research involved an examination of the mean yearly air temperature, overall annual rainfall, fluctuations in river discharge, vegetation cover, and alterations in vegetation types within the selected basin stations. This was accomplished through the utilization of hydro-meteorological analysis, satellite assessment, land cover determination, and statistical analysis. Over the course of the study, it was observed that the average annual air temperature increased at all stations (with a positive change of Z = +1.16). The amount of precipitation decreased (Z = −0.79), especially from 2000 to 2014, and its statistical significance decreased. During the study period, average river discharge significantly decreased (Z = −3.51). Due to these combined factors, the lake’s water level also decreased (Z = −2.03). Vegetation cover change varied in high mountains, near river and lake water surfaces, and in arid regions. Changes in air temperature and precipitation in the current year determine vegetation cover. Because of the large amount of precipitation in the summer months from 2000 to 2010 and 2020, the growth of vegetation cover during that period was relatively good. This study was conducted in arid and semi-arid regions of Central Asia and demonstrates the impact of climate change on changes in vegetation cover.

Published: October 2023

In this study, apricot-pit-based activated carbon was functionalized and used as a sorbent for the preconcentration of lead (Pb2+) in different water and food samples. The activated sorbent was modified with ethylenediaminetetraacetic acid (EDTA) to enhance its selectivity for the efficient removal of Pb2+ ions. The modified activated sorbent was characterized using FTIR, an SEM, BET, and TGA. The column adsorption method was used to study the adsorption capacity of synthesized and modified activated carbon and analyzed using atomic absorption spectrophotometry. A multivariate procedure, i.e., Plackett–Burman design (PBD) and central composite design (CCD), was studied for optimizing the adsorption process, which allows the optimization of multiple variables at the same time. An interference study was conducted to ascertain the selectivity of the developed method. The developed method was validated by assessing certified reference materials and additional standards for Pb2+ detection in real samples. To assess the precision of the proposed procedure, repeatability (RSDr) and reproducibility (RSDR) were calculated, which were determined to be <3.0 (n = 7) and <7.5 (n = 15), respectively. The obtained results revealed that the modified AC is a suitable and efficient sorbent for the preconcentration of Pb2+ in real water and food samples.

The Perrot Spring (1300 m a.s.l.), located to the right of the Chalamy valley in the Monte Avic Natural Park (Valle d’Aosta, Italy), is an important source of drinking water for the municipality of Champdepraz. This spring is located on a large slope characterised by the presence of a Quaternary cover of various origins (glacial, glaciolacustrine, and landslide) above the bedrock (essentially serpentinite referred to the Zermatt–Saas Zone, Penninic Domain). Water emerges at the contact between the landslide bodies and impermeable or semi-permeable glaciolacustrine deposits. The aim of this study is to define the processes and recharge zones of this spring. The analysis of the data revealed the presence of two contributions to the Perrot Spring input: a spring thaw contribution defined by a small increase in flow and an autumn contribution from rainwater infiltration. The low average temperature and low variation of the annual temperature (4.8–6.5 °C) suggest a sufficiently deep flow circuit. Chemical analyses showed a groundwater chemistry consistent with the regional geology: the hydrochemical facies is calcium–magnesium bicarbonate and isotopic analyses (δ2H and δ18O) of rainfall and spring water suggested a recharge altitude of about 2100 m a.s.l. In conclusion, this study makes it possible to recognize the water inputs to the spring discharge and to delineate its recharge area, which can be proposed to implement strategies to protect the resource.

Published: October 2023

Soil moisture is essential parameter in the Earth’s surface. The information provided by soil moisture plays a vital role in agricultural production, eco-environmental protection, water and land resources management, etc. Meanwhile, the accurate monitoring of the spatial and temporal distribution of soil moisture is of great significance for the engineering geological assessment and geological disaster prevention. Monitoring and retrieving soil moisture via remote sensing data and mathematical models are the main research methods at present and the crucial issue is how to eliminate the influence of other surface and soil parameters like roughness and soil bulk density, and the interference of vegetated areas to electromagnetic waves. Nowadays, many branches of retrieval methods have been developed, and researchers are integrating multiple models to improve the retrieval accuracy. This paper summarizes the present research status and progress of soil moisture retrieval via remote sensing based on four kinds of models: empirical model, semi-empirical model, physical model, and machine learning. The soil moisture products are summarized and listed at the same time. The difficulties and issues in the present research are discussed and the future outlook is explored.

Published: October 2023

The grinding reinforcement of fine sand layers is a difficult problem in dam engineering construction. As a new type of grouting material, permeable polymer with excellent impermeability and high strength is widely used in dam engineering. In this paper, a series of compressive tests were designed considering different grouting pressures, curing days, moisture content, and porosity of fine sand. The influence of grouting parameters and sand layer conditions on the strength of fine sand layers reinforced by permeable polymers was analyzed. SEM and XDR tests were conducted to analyze the microscopic characteristics of the grouting stone. The functional calculation model of the strength and the influencing factors was established to explore the main factors influencing grouting stones. The compressive strength of grouted stones increases rapidly from the 7th to the 14th day, reaching about 96% of the maximum strength. The degree of influence of different factors is grouting pressure > moisture content > porosity. The compressive strength of the grouted stones increases with the increase of grouting pressure and the number of curing days. The compressive strength decreases with the sand layer’s increasing moisture content and porosity.

Published: October 2023

A continuous stirred tank reactor (CSTR) was utilized in this study to enrich and cultivate anaerobic ammonia oxidation process (ANAMMOX) granular sludge by gradually decreasing its pH, and to investigate the effects of different concentrations of ferrous ions (Fe2+) on the activity of ANAMMOX granular sludge cultivated under biased acidic conditions. The final nitrogen removal of ANAMMOX deteriorated at pH 6.30–6.50 after 220 days of continuous operation, but the nitrogen removal of ANAMMOX was favorable at pH 6.50–7.00. This indicates that a slightly acidic environment (pH = 6.50–7.00) promotes the activity of ANAMMOX, but the pH should not be too low (pH = 6.30–6.50). In the reactor, Candidatus Kuenenia was consistently the dominant ANAMMOX genus and its abundance declined from 11.70% on day 1 to 10.44% on day 220. As Fe2+ concentrations were increased (10, 20, 30 mg/L) in ANAMMOX granular sludge cultured in an acidic environment, the nitrogen removal effects gradually increased. In addition, with the increase in Fe2+ concentrations, the total nitrogen removal load (NRL) in the reactor was increased from 1.16 kg/(m3/d) to 1.42 kg/(m3/d). Increases in Fe2+ concentration did not result in inhibition of ANAMMOX, which may be attributed to the morphology of sludge and the shape of the reactor. As a result of the present study, new insights were gained into the physiological characteristics of ANAMMOX in an acidic environment over the long term, and how Fe2+ affects its ability to remove nitrogen from the environment.

In the process of exploitation, the animals of the main herd constantly reduce their productivity, and may also depreciate due to a decrease in their cost, obsolescence and unsuitability for further use. In this regard, there is an objective need for periodic monitoring of depreciation and the organization of timely accounting for the culling of animals from the main herd. Therefore, the article substantiates the provisions for monitoring and accounting for the depreciation and culling of animals from the main herd. A methodology has been developed for determining the cost and accounting for depreciation, as well as culling animals from the main herd, their sale and fattening.

Published: October 2023

In the modern educational environment, the emphasis on linguistic competence formation becomes crucial since globalization and international cooperation foresee a significant impact of language training on key processes in education. This article examines modern trends in the usage of innovative pedagogical technologies in higher education to deepen the linguistic competence of students of higher education institutions. The author analyzes the role of innovations in pedagogy and linguistics and highlights the advantages of using these technologies in the environment of higher education institutions.

The author focuses on the study and analysis of such approaches as the Flipped Classroom, case study technology, and literary analysis of cases, the usage of virtual reality, and the project activity method.

The article highlights how these innovative methods can change the traditional approach to language learning, allowing higher education students to actively engage in foreign language learning and develop their linguistic competence. Flipped Classroom allows you to shift the emphasis from lecture teaching to the independent work of higher education students, while case study technology stimulates analytical thinking and solving practical problems. Literary analysis of cases contributes to the study of real situations of using a foreign language, and the usage of virtual reality makes learning more exciting. The method of project activity supports the development of communication and organizational skills of educational process participants.

All these pedagogical approaches are considered in the context of their influence on the deepening students’ linguistic competence and the possibilities of their active learning and self-development. The study offers an efficient contribution to the usage of innovations in higher education to improve the effectiveness of foreign language and linguistic disciplines.

Intervenants sociaux et populations « jeunes en difficulté ». Un difficile rapport à l’institué
Authors: Mathey-Pierre Catherine
Published: October 2023

Une enquête menée en 2001 sur le thème « Intervenants sociaux et insertion » montre, à travers l’exemple d’un quartier de la Seine-Saint-Denis, la grande complexité du travail de ces professionnels. Il est question ici de la tension qu’ils rencontrent dans leurs pratiques entre le maintien d’une nécessaire proximité avec les jeunes « en difficulté » dont ils ont la charge et leur position par rapport à leur institution et dans certains cas à la loi. Comment concilier continuité du travail auprès de populations « en marge » et appui sur l’institué, en particulier lorsque le sens de ce dernier n’est pas clair ?

L’évitement scolaire par déménagement
Authors: Korsu Emre
Published: October 2023

Entre les stratégies d’évitement pouvant être menées à domicile constant, les stratégies interventionnistes permettant l’obtention de conditions de scolarisation «acceptables» et les dynamiques locales favorisant la constitution d’écoles et de collèges publics recrutant un public plutôt favorisé, les familles culturellement nanties semblent disposer d’un arsenal d’alternatives pour apporter au problème scolaire une solution de proximité sans changement de domicile.

Droit à la différence ou différence de droits ?
Authors: Crahay Marcel
Published: October 2023

Inventer une école et un système de formation plus justes nécessite de revenir sur les facilités d’une école sur mesure, d’un égalitarisme grand teint ou du droit à la différence. Les mécanismes psychosociaux générateurs d’inégalités doivent être revus à la lumière d’une interrogation sur le bagage commun de compétences nécessaire, sur le droit à la formation pour tous et sur des dispositifs d’orientation respectant les principes de justice.

L’innovation comme tradition au lycée de Jaunay-Clan
Authors: Noble Dominique
Published: October 2023

Le lycée pilote innovant (LPI) de Jaunay-Clan en est à sa dix-huitième année d’existence. Son équipe, très largement renouvelée au cours des années, n’a cessé depuis son inauguration de développer une expérience innovante dont l’originalité tient au fait qu’elle se déroule dans un lycée qui ne dispose d’aucun statut expérimental particulier. C’est sans doute pourquoi les pratiques mises en oeuvre au LPI sont en partie transférables, même si elles restent relativement fragiles.

Published: October 2023

Notre démocratie souffre de l’autoreproduction des élites et la société est chaque jour davantage consciente de cette difficulté. Pourtant, il n’est pas encore possible d’espérer rapidement une réforme des concours d’entrée des grandes écoles. La discrimination positive semble dès lors la meilleure solution pour diversifier socialement leur recrutement. Sciences Po nous en a donné récemment l’exemple.
