IntroductionIntercropping practices play a crucial role in enhancing and maintaining the biodiversity and resiliency of agroecosystems, as well as promoting stable and high crop yields. Yet the relationships between soil nitrogen, microbes, and yield in maize cultivated under maize/soybean intercropping systems remain unclear.MethodsTo fill that knowledge gap, here we collected maize rhizosphere soil at the staminate stage after 6 consecutive years of maize/soybean intercropping, to investigate how intercropping and nitrogen application rates affected nitrogen utilization by crops and soil microbial community composition and function. We also examined correlations of those responses with yields, to clarify the main ways that yield is enhanced via intercropping and by nitrogenous fertilizer gradient changes generated by different nitrogen application rates.ResultsThe amount of applied fertilizer was 240 kg N ha-1 was best for obtaining a high maize yield and also led to the greatest nitrogen-use efficiency and bacterial diversity. Under the same N application rate, intercropping increased the maize yield by 31.17% and soil nitrogen (total, ammonium and nitrate nitrogen) by 14.53%, on average, in comparison to monocropping. The enrichment of Gemmatimonas and Bradyrhizobium significantly increased the soil nitrogen content, and a greater relative abundance of Sphingomonas and Gemmatimonas increased the maize yield, whereas enrichment of Candidatus_Udaeobacter and Bradyrhizobium decreased it. The benefits of intercropping mainly arise from augmenting the abundance of beneficial microorganisms and enhancing the efficiency of N use by crop plants.DiscussionThis study’s findings are of key importance to bolster the stability of agro-ecosystems, to guide the scientific rational use of nitrogen fertilizers, and to provide a sound theoretical basis for achieving the optimal management of intensive crop-planting patterns and green sustainable development.

BackgroundMarital satisfaction is one of the important components of quality of life. Women’s marital satisfaction is affected when they enter the middle age period, due to the mental and emotional tensions caused by the physical changes. In this regard, the present study aimed to investigate the association of quality of life with marital satisfaction, stress, and anxiety in middle-aged women referring to health centers of Ahvaz city, Iran.MethodsThis cross-sectional descriptive-analytical study was conducted on 1,000 middle-aged married women (30–59 year of age) under the auspices of health centers of Ahvaz city, Iran in 2019. The subjects were selected by simple random sampling method, and were asked to complete demographic characteristics, quality of life questionnaire, Enrich marital satisfaction questionnaire, Holmes-Raheh stress questionnaire, and Spielberger state–trait anxiety inventory. The data were analyzed by using SPSS 0.22 software through mean, standard deviation, frequency, Pearson correlation and regression (p = 0.05).ResultsBased on the results, 42.4% of the participants were between 40 and 50 years of age, 35.6% had a high school diploma, and 50% of them were housewives. Also, the results of Pearson’s correlation showed a positive and significant relationship between quality of life and marital satisfaction (r = 0.178) (p &lt; 0.001). However, quality of life had a negative and significant relationship with anxiety (r = −0.552) (r &lt; 0.001) and stress (r = −0.188) (p &lt; 0.001).ConclusionGiven the positive and significant relationship between quality of life and marital satisfaction, appropriate trainings are highly recommended for couples to increase the quality of life and marital satisfaction of middle-aged women and thus strengthen the health of family and society.

BackgroundMental health challenges are encountered by frail older adults as the population ages. The extant literature is scant regarding the correlation between depressive symptoms and social participation among frail older adults.MethodsThis study is based on an analysis of data from China Health and Retirement Longitudinal Study (CHARLS) participants aged 60 and older who are frail. A frailty index (FI) was developed for the purpose of assessing the frailty level of the participants. Additionally, latent class analysis (LCA) was employed to classify the participants’ social engagement patterns in 2015 and 2018. The study used ordered logistic regression to examine the relationship between social participation type and depressive symptoms. We also used Latent Transition Analysis (LTA) methods to explore the impact of changes in social activity types on depressive symptoms after three years of follow-up in 2018. In addition, the response surface analysis (RSM) investigation explored the relationship among FI, depression, and social participation.ResultsA total of 4,384 participants completed the baseline survey; three years later, 3,483 were included in the follow-up cohort. The baseline survey indicates that female older adults in rural areas who are single, have lower incomes, shorter sleep durations, and lighter weights exhibited more severe depressive symptoms. Social participation patterns were categorized into five subgroups by LCA. The findings indicate that individuals classified as “board game enthusiasts” (OR, 0.62; 95% CI, 0.47-0.82) and those as “extensive social interaction” (OR,0.67; 95% CI, 0.49-0.90) have a significantly lower likelihood of developing depressive symptoms compared to the “socially isolated” group. We also discovered that “socially isolated” baseline participants who transitioned to the “helpful individual” group after three years had significantly greater depressed symptoms (OR, 1.56; 95% CI, 1.00-2.44). More social activity types and less FI are linked to lower depression in our study.ConclusionThe results of the study emphasize the importance of social participation patterns and the number of social participation types in relation to the severity of depression among frail older adults individuals. This study’s findings may provide important insights for addressing depressive symptoms in frail older adults person.

IntroductionThis study aims to develop a comprehensive evaluation model for urban tourism competitiveness in China. Given China's transition into a mature tourist destination, there is a pressing need for a framework that can assess the effectiveness of its urban tourism strategies. The model presented in this study is designed to provide a holistic understanding of the factors influencing urban tourism competitiveness in the Chinese context.MethodsThe methodology employed in this study combines both qualitative and quantitative approaches. A modified version of Porter's Diamond Model serves as the primary framework, augmented by the IMD World Competitiveness Center: International Institute for Management Development (IMD) framework to incorporate social governance and environmental dimensions. To derive comprehensive scores for sustainable development, a linear weighted evaluation method was used, incorporating the coefficient of variation entropy weight method. This approach allows for a quantitative assessment of urban tourism competitiveness from 2008 to 2019.ResultsThe key findings of the study reveal significant challenges within the current urban tourism landscape in China. These challenges include homogeneous competition, a lack of strategic management, and insufficient service quality. Furthermore, the study identifies the need for greater emphasis on sustainable tourism development, balancing economic benefits with the preservation of cultural and natural assets.DiscussionBased on the findings, the study proposes several solutions to address the identified challenges. These solutions include creating boutique inland tourism routes, developing unique urban tourism brands, and enhancing regional cooperation and management practices. Additionally, the study emphasizes the importance of integrating community development and services into the evaluation model to foster sustainable tourism development. The proposed solutions offer actionable insights for policymakers and planners seeking to improve the competitiveness and sustainability of urban tourism in China.

Published: September 2024

IntroductionExplanatory models of disease focus on individuals’ and groups’ understandings of diseases, revealing a disconnect between livestock keepers and animal health providers. Animal health providers rely on models grounded in their veterinary training and experience. At the same time, livestock keepers may construct models based on traditional knowledge and their lived experience with East Coast fever in their cattle herds. To better understand East Coast fever and develop more efficient management strategies, this ethnographic study used the explanatory models’ framework to provide a structured way for comprehending and contrasting different beliefs and understandings of East Coast fever as perceived by the livestock keepers across the different livestock production systems.MethodMultiple data collection methods were employed, including unstructured observations, 30 in-depth interviews (IDIs), 18 focus group discussions (FGDs), and 25 key informant interviews (KIIs).ResultsAdult cattle, calves and sheep were perceived as susceptible to East Coast fever. However, there were varying perceptions of livestock susceptible to East Coast fever in the different livestock production systems. East Coast fever was attributed to multiple factors, including ticks, tsetse flies, mosquitos, birds, stagnant, dirty, or contaminated water, and livestock-wildlife interactions. However, some aspects were specific to the production system. Livestock keepers classified diseases based on observable signs, grouping diseases with similar signs under the same classification. Moreover, livestock keepers described different forms of East Coast fever ranging from treatable to fatal, which could be distinguished by the signs they presented. Self-treatment with drugs from the local agro-vet shops was the initial course of action during suspected cases of East Coast fever. Animal health practitioners were the last resort if self-treatment did not produce the desired outcome. Livestock keepers perceived avoidance of stagnant or contaminated water, tick control, and fencing as effective control measures for East Coast fever in their livestock herd. Very few livestock keepers were aware of an East Coast fever vaccine.DiscussionMechanistic explanations hold little significance in controlling East Coast fever. Instead, understanding and addressing livestock keepers’ beliefs regarding ECF is crucial for promoting behaviors that support interventions across different livestock production systems.
Teaching and learning for sustainable futures: Reclaiming, collaboration and empathy
Authors: Berman Kim Shelley 
Published: September 2024

Introducing community engagement to my annual class of Visual Art honours students has become increasingly challenging. There is a healthy resistance to the perception of ‘cultural tourism’, and students are sensitive to the idea of entering a community as voyeurs with the perception of privileged “saviours”. I offer a particular example of an emerging annual exchange with the African Reclaimers Organisation (ARO), who have partnered with the University of Johannesburg (UJ) in a range of projects that can add value to upcycling of collected and sorted waste products. The pervasive news of corruption, violence, and rolling blackouts undermines well-being and increasingly perpetuates despair, apathy, or distraction. In this climate, a question of response in an educational environment is pertinent. How does one teach and learn about sustainable futures? How can educators foster empathy, agency, and activism among students? This article draws on ecology activist and scholar Dylan McGarry’s expanded concept of transgressive social learning using skills transfer through an apprenticeship, which is helpful in framing a model of teaching and learning based on social exchange. Including selected student reflections, the paper considers methods and practices that model ways to develop various forms of personal and social agency through exploring empathetic encounters.

This research analyses the behavior of corrosion, durability, and quality of reinforced concrete samples coated with two different materials when exposed to contaminated soil with sulfates. The initial assessment involved evaluating the water absorption rate of the coating materials before and after exposure to a solution containing 3% Na2SO4 + 3% MgSO4 + 3% K2SO4 + 3% CaSO4 to determine their durability. The corrosion potential and linear polarization resistance technique were employed to measure the corrosion rate. Carbon steel and AISI 304 steel bars were tested alongside a stainless counter electrode. The findings indicate that the solvent-based coating exhibited superior performance, demonstrating reduced corrosion and water absorption rates. Additionally, the presence of sulfates led to the formation of a surface layer on the concrete, initially aiding in limiting water penetration. However, over time, this layer eventually causes damage to the concrete from the inside out.
FIRE RISK ASSESSMENT METHOD OF TRANSPORTATION OF LIQUEFIED PETROLEUM GASES ALONG A SECTION OF TRACK PASSING NEXT TO A PASSENGER RAILWAY PLATFORM

Published: September 2024

Действующая в настоящее время Методика определения расчетных величин пожарного риска на производственных объектах не содержит методов оценки величины пожарного риска при транспортировке пожароопасных грузов. При этом значительное количество инцидентов при их транспортировке, сопровождающихся, в частности, пожарами, показывает необходимость учета угрозы жизни и здоровью людей, как перемещающихся по путям сообщения, так и находящихся в непосредственной близости от них. В настоящей работе предложен метод оценки величины индивидуального и социального пожарного риска для лиц, находящихся в поездах пригородного сообщения и на платформах во время транспортировки сжиженных углеводородных газов.
The current methodology for determining the calculated values of fire risk at industrial facilities does not contain methods for assessing the fire risk value during the transportation of flammable cargoes. The high number of transport incidents involving flammable cargoes, including fires, also highlights the need to take into account threats to life and health both of people travelling along the routes and those in their immediate vicinity. This paper proposes a method for assessing the value of individual and social fire risk for persons on commuter trains and on platforms during transportation of liquefied petroleum gases. As an example, there is considered a rectilinear double-track section of a railway track, along which transit transportation of LPG tanks is carried out. A commuter train and platform is located on the railway section. There are considered the cases of people being on the platform and in a local train. There is taken into consideration the time required to evacuate people from the wagon when calculating the fire risk. It was found that the greatest contribution to the value of potential fire risk is provided by the scenarios of a flash fire, as well as a fireball. Based on the conducted approbation of the fire risk assessment method, it can be concluded that the results obtained through the proposed methodology qualitatively coincide with those obtained in other publications. At the same time, calculations carried out using this method make it possible to calculate the fire risk value for railway passengers.

Résumé La principale bénéficiaire du classement international des universités est l’industrie de l’édition en langue anglaise. Classer les universités fournit des informations qui intéressent et contribue à augmenter considérablement la vente des journaux. Parce que la place d’une université dans les classements mondiaux (le Times et le Shanghai Jiao Tong ) dépend fortement de la publication dans les revues internationales à comité éditorial, principalement en langue anglaise, revues la plupart du temps contrôlées par les multinationales de l’édition telles que Thomson Scientific, ces classements augmentent du même coup la publication et la vente de revues à fonds privés. Ces classements et ces palmarès n’ont absolument rien de scientifique, ils sont opaques dans leur mode d’évaluation des universités et commencent à avoir un impact négatif sur la qualité de la formation et de la recherche dans les universités.

Résumé	L’évolution du métier des enseignants-chercheurs et de leurs tâches, a été peu étudiée par la sociologie de l’éducation davantage centrée sur des questions comme celles posées par les apprenants. L’analyse comparée d’une documentation institutionnelle publiée en France et d’ouvrages scientifiques portant sur les enseignants-chercheurs permet cependant de repérer les contours d’une profession : missions, tâches, modes de recrutement, d’évaluation..., que l’institution a constamment modifiée à partir des années 1970. Sont en particulier pointées les difficultés liées à la mise en place de politiques d’établissements confrontés à de nouveaux défis sociaux et à l’articulation de la recherche avec les différentes missions qui incombent aux enseignants-chercheurs comme élément de structuration de leur métier.
