Drought frequency and severity intensify with climate change, challenging many Mediterranean cities to face securing sustainable water supplies. In this context, groundwater emerges as a key but often overlooked resource, particularly in urban areas historically reliant on external drinking water systems. This study provides a comprehensive hydrogeological characterisation of the groundwater system in Aix-en-Provence (southeastern France), with a specific focus on hypothermal springs and the cold springs of the Vallon des Pinchinats, which historically supplied the town before the creation of the Canal de Provence by the company of the same name (Société du Canal de Provence (SCP)). By combining chemical and isotopic analyses (δ¹⁸O, δ²H, and chloride concentrations) with a statistical clustering (DACMAD method), we characterise the origin and dynamics of distinct water sources and evaluate their influence with surface water and external supply systems. Four key hydrological entities influencing the study area were identified. (1) regional precipitation (RRW) contributing significantly to groundwater recharge in the region. The isotope composition of the RRW was calculated (δ¹⁸O: −6.68‰, δ²H: −41.80‰, Cl: 2.2 mg/L) (2) Groundwater from the Oligocene aquifer (OG) characterised by an enrichment in chloride and sulphate. (3) Groundwater from the Cretaceous–Jurassic aquifer (CJG), a karstified aquifer from the Sainte-Victoire-Concors massif, which supplies the cold and hypothermal springs in Aix-en-Provence and multiple springs in the region. (4) Canal de Provence water (CPW) as an external water source, used for domestic supply, which has left a traceable signal in the local hydrosystem. The study reveals that cold springs of the Vallon des Pinchinats result from the mixing of Oligocene and Cretaceous–Jurassic groundwaters. Hypothermal springs (20–30 °C) circulate at moderate depths (165–500 m), unlike previous models suggesting deeper infiltration and mixing processes. This study contributes a novel hydrogeochemical and isotopic framework applicable to other Mediterranean urban areas facing similar pressures and highlights the strategic role that local groundwater can play in building long-term water resilience.

Estimating leaks in urban gas distribution systems is crucial for reducing greenhouse gas emissions from fugitive losses and mitigating costly waste. This study aimed to use a simplified methodology to estimate pipeline leakage in gas distribution systems and validate these estimations against established benchmarks or other gases globally. The estimation encompassed sources including third-party damage, long-term permeation, flaring, and purging during pipeline commissioning and decommissioning, as well as fugitive leakage, each requiring respective evaluation. Results showed that the total town gas leakage volume was around 695,044 m³ to 2,009,991 m³, accounting for 0.045% to 0.13% of the total town gas sales in 2022. Among the five leakage sources, fugitive leakage was the major contributor with the leakage volume of 1,938,914 m³. To comprehensively benchmark all emission factors (EFs), those from previously reported studies were adapted to the town gas scenario and combined with the current activity factors (AFs) in Hong Kong to calculate the leakage amounts. Comparing our results with different models, we observed variations in estimated leakage amounts based on years, regions, and sampling methods. Upgrades in pipeline materials led to reduced EFs and subsequently lower total gas leakage. Our findings support efforts to reduce greenhouse gas emissions by providing actionable data for policymakers and utility companies to address gas leakage issues. Full article

Sexist ideologies and attitudes perpetuate gender inequalities in both private and public contexts. Traditional views of sexism emphasize hostility, but the phenomenon is more complex, involving interdependent power relations between men and women. The Ambivalent Sexism Theory identifies two forms: hostile sexism (HS) and benevolent sexism (BS). This study aimed to measure the levels of HS and BS among men in a northern Italian town, examining sociodemographic factors associated with elevated sexism scores. A paper questionnaire was administered by a volunteer organization and the Local Health Authority to male individuals over 18 in Cesena from February to April 2023. The convenience sample was recruited from diverse settings, including universities, companies, cafes, and hospitals. The Ambivalent Sexism Inventory (Glick & Fiske) was translated into Italian and used for data collection. A total of 275 participants were included. The mean age was 44.4 years, with a diverse educational background. Regression analyses revealed that higher education levels were associated with lower HS scores with a high school education and a bachelor’s degree or higher showing statistically significant coefficients of −5.33 (SE = 2.26, p = 0.019, and 95% CI: −9.78–−0.88) and −8.64 (SE = 2.51, p = 0.001, and 95% CI: −13.58–−3.69), respectively, if compared to individuals with middle school education or less. Age was a significant predictor of BS, with older individuals showing higher BS scores (Coeff. = 0.20, SE = 0.05, p < 0.001, and 95% CI: 0.10–0.31). Healthcare professionals had higher HS scores, while unionists had both lower HS and BS scores. This study highlighted the levels of both HS and BS in various professional and social contexts. Education appears to be a critical factor in reducing HS, while age influences BS. Full article

Access to reliable water supply is critical for sustainable development and public health, yet many peri-urban and rural communities in the developing world face challenges such as poor maintenance, faulty infrastructure, and inadequate governance of water services, hindering the UN’s Sustainable Development Goals (SDG). In Emina-Boadi, a small town in Kumasi, Ghana, residents increasingly rely on boreholes due to substandard service from the Ghana Water Company Limited (GWCL). This shift highlights concerns about water reliability, quality, and affordability, impacting public health and hindering progress toward SDG 6. This case study assesses water service levels using key performance indicators (KPIs) such as quantity, quality, affordability, accessibility, and reliability, focusing on sources like boreholes, hand pumps, piped water, hand-dug wells, rainwater, and surface waters. The study aims to delineate the roles of different water providers, understand community dynamics, and evaluate contributions to rural development and SDG 6 through stakeholder interviews and questionnaires. By leveraging the WASHCost framework, which aims to improve planning methods and the provision of water and sanitation services by addressing the lack of cost information in rural and peri-urban areas, and the Joint Monitoring Programme (JMP) framework, which monitors progress toward global targets related to water, sanitation, and hygiene, the study categorizes indicators and draws connections among them. The findings reveal a significant preference for borehole services, with 87% usage and an 83% reliability rate compared to 13% for GWCL. Daily water consumption averages 60.75 L per person, with on-premises access improving water collection efficiency to 7 min. Dissatisfaction with GWCL services highlights the need for improved delivery aligned with community needs and SDG targets. Adopting sustainable management practices, enhancing infrastructure, and improving governance are crucial for ensuring safe and affordable water access for all residents of Emina-Boadi and similar communities.

This paper investigates the conditions and consequences of integrating small towns into industrial production networks. It is based on empirical research conducted in Algeria, a hydrocarbon-dependent rentier economy characterized by significant regional inequalities and the political aims of economic diversification and spatial rebalancing. Elaborating the case study of a state-owned cement factory in the small town of Sigus, the research provides insights into the multiple roles of the state in shaping production network integration and the characteristics of small towns as economic locations. The methodology combines secondary data and information with primary research based on semi-structured interviews. It reveals the importance of a multi-scalar regional framework in production network integration, whereby national factors played a key role due to the centralized Algerian state, the state-owned character of the investing company, and the shortcomings of the small town’s local environment. It emphasizes the contradictory impacts of production network integration in economic, social, and environmental terms, primarily on a local level. These contradictions underscore the necessity for critical evaluations to maximize the benefits of production network integration while mitigating its adverse effects. They also call for the more consistent involvement of the local community in similar economic development decisions. Notably, this research contributes significantly to the existing body of literature by addressing the underexplored topic of integrating small towns into production networks within the Algerian context. Doing so offers a more nuanced understanding of the particular economic, social, and environmental dynamics at play in these locations, thereby enriching the discourse on economic development strategies for small towns in rentier economies like Algeria.

This article merges evaluations of Black life through the Southern Gothic and the intersection of Black studies to conceptualize the “Black Gothic”. The Black Gothic conceives of a future that requires closely examining the past and the present primarily through a Southern Gothic and Black horror lens. Much of Black Gothic’s analytics depended upon the framework outlined within Afro-pessimism and the subprime; however, it differs in its pursuits of reparations as a way forward. The Black Gothic focuses on intermingling the lived anti-Black experiences of Black existence with supernatural gothic traditions, forcing readers to determine which experience is more horrific. The Black Gothic functions as a mode of interaction with the Southern Gothic and the Black horror visual genres; its definition invokes literary and visual modes and genres that expand the many depictions of Black life in America when it is constantly threatened by elimination and devaluation. The Black horror genre seeks to expose the “afterlife of slavery” through actual and speculative means. Meanwhile, Southern Gothic’s ability to cross temporal bounds makes these the ideal genres to present the enslaved’s repressed and debted history. Southern Gothic replaced ruined gothic castles with plantations; Black Gothic replaced plantations and the monolithic “South” with northern sundown towns, redlining, and subprime mortgages. The Black Gothic’s methodology uses a systemic fiscal devaluation of Black ownership, self, and property through the subprime. In company with Fred Moten’s conceptualization of the subprime, the Black Gothic views being marked as “subprime” as an antecedent to predatory housing practices; it is instead the moment that captured Africans experience social death. Using Toni Morrison’s Beloved and Misha Green’s HBO adaptation of Matt Ruff’s novel Lovecraft Country, I define the Black Gothic and then outline its capacity to function as an analytic to further both the Southern Gothic and Black horror genres. The Black Gothic transcends gothic traditions by including films and texts that are not categorically gothic or horror and exposes the horrific and gothic modes primarily exhibited through the treatment of the descendants of enslaved Africans. Comprehensively, this article argues for a space to view the future re-evaluation of Black life through speculative and practical reparations. Full article

We continue to think about a conventional work model. Full article

Wastewater management in Bogor, Indonesia faces significant challenges in achieving sustainability. The success of the development of wastewater management requires an analysis of the characteristics of the actors related to the relationship between actors, the attitude of actors toward development goals, and the possibility of alliances and conflicts that arise. The research aims to identify the actors’ typologies based on the strengths and relationships between the actors’ and the actors’ attitudes toward managing fast-growing areas in self-help settlements based on domestic wastewater management for the area of Bogor Town, Indonesia. This research uses a case study approach, and data were collected through observation, interviews, and focus group discussions. Data analysis used the MACTOR method (Matrix of Alliances and Conflicts Tactics, Objectives, and Recommendations) to identify the stakeholder actors’ strengths, relationships, and patterns of alliances. The results showed that the most influential actors in wastewater management are the Housing and Settlements Agency (DISRUMKIM), Regional Drinking Water Companies (PDAM), entrepreneurs (PUSAHA), MEDIA, the Regional People’s Representative Council (DPRD), Regional Development Planning Agency (BAPPEDA), Public Works and Spatial Planning Service (DPUPR), and the Health Service (DINKES). In addition, the highest divergence value was 35, which occurred in Sub-District Tanah Sareal (KEC. TANSAR) to PUSAHA. There are four actors with a high level of ambivalence, namely Sub-District Bogor Selatan (KEC BOSEL), Regional Disaster Management Agency (BPBD), MEDIA, and Environment Service (DLH). These findings form the basis for developing a pattern of collaboration between all stakeholders necessary for the development of sustainable wastewater management in Bogor, Indonesia. In addition, this finding allows it to be used as relevant information, and it can be implemented in other cities with the same characteristics as Bogor Town is facing similar challenges in wastewater management.

LCA methodology is often used in public procurement decision making. The European Commission introduced Life Cycle Costing (LCC) in 2014 to support this methodology. LCCs take into account costs incurred during a service, work or product’s lifetime. Application management techniques of LCC offer a better awareness of the factors that influence the resources and costs in the case of procurements. The identification of the factors that influence the costs is the main key of the LCC tool. In such a way, the life cycle management is focused on efficient purchasing. The awareness levels of the LCC criteria influence the cost and will also highlight other aspects of existing products that could benefit from the involvement of life cycle management. Taxi transport services (as an alternative to public transportation) are a sector of the economy with a good income when acquisitions are properly carried out. When the acquisitions are analyzed, governmental and local regularizations should be taken into account. Today, cities, as well as small towns, look forward to improving the quality of life of the citizens and reducing pollution. The acquisitions of buses/cars for public use must be carried out with respect to the required performance of the cars. On the one hand, the municipality should be in line with the European Commission’s policy; on the other hand, it should be in line with the state’s public procurement requirements. An acquisition must also be reasonable in terms of price, lifetime, environmental impact, circular economy and meeting citizens’ needs. The goal of this paper was to analyze the acquisition of cars for taxi services from the perspective of public procurements. The study was performed with the help of the Taxi LAL company from Bacau County. The LCC techniques were applied to identify the most “acceptable” as well as the most “profitable” choices for taxi services. For a better understanding of the problem, within the present paper the mechanism of cost assessment for a product modernization was exemplified. Full article

In 2019, Indonesia’s electricity consumption exceeded 278 TWH, or about 1.08 MWh/capita. This value shows a considerable increase in electricity consumption which has doubled in just a decade. Previous studies have shown that the proportion of electricity consumption used for lighting needs is correlated to the country’s GDP. This is generally around 20 to 50% of electricity production but can go up to 86% in the case of Tanzania. Indonesia is the 4th country in the world in terms of population and its lighting market as well as its lighting-related energy consumption has a strong impact on several levels: societal, environmental but also economic and energy. Having a knowledge of the lamps used by the Indonesian people is therefore particularly interesting and important, in particular in the context which presents a great societal diversity but also in a context of energy saving. Indonesia is an archipelagic country made up of 5 large islands and over 17,000 small islands with widely varying levels of population density. This island geography leads Indonesia to face challenges in the distribution and production of electrical energy, which affects the use of lamps in various types of regions. The overview of this study was done by collecting data from various sources, especially BPS (Biro Pusat Statistik/Statistic Center Bureau of Indonesia), CLASP (an NGO for clean energy), the Ministry of Energy and Mineral Resources of Indonesia (ESDM), PLN (Indonesian Electrical Company), etc. The data obtained from these sources provides several descriptions of general lighting conditions in Indonesia viewed from several angles, such as growth of lamp market, use of lamp types, percentage of use of lamps with energy saving (ESL), etc. Considering that Indonesia has various regional characteristics, in this study, the survey of a total of 394 respondents was conducted on the use of lamps by creating regional categories based on electrical conditions, power consumption, and electricity per capita, among others. The categories of areas observed fall into 5 types based on their population and geography: large cities, small towns, rural/village areas, islands and remote areas. The results of compiling data from these various sources show that the types of lamps used by Indonesians follow the lighting trend in the world. The use of LED lamps has a utilization percentage of around 52%, much higher than other types of lamps such as CFL, fluorescent or incandescent. Based on the survey conducted, it is known that the widely used LED power is between 1 and 10 watts with a usage time of 8 to 12 h per day. In the next few years, it is estimated that the use of LEDs in Indonesia will increase as the government has prepared various regulations and policies related to energy saving, one of which relates to lighting.

This paper shows the technical–economic assessment of two power systems based on renewable electricity to cover the energy consumption requirements of a drinking water treatment plant in the town of Pile, Ecuador, with a planning horizon of 15 years. A stand-alone and a grid-connected solar PV system were proposed to power this plant, which was designed considering the maximum daily potable water supply condition. This plant operated under two scenarios: (1) 12 h during daylight hours and (2) 24 h. Both schedules were proposed to assess the impact of PV power systems on plant operation. We modeled and optimized a total of four scenarios, where each scenario consisted of one of the proposed PV power systems and the plant with one of its operating schedules. Homer Pro software was used to size and find an optimal solution in each scenario, considering the net present cost (NPC) as the main criterion for optimization. The results showed that the change in the plant operation schedule significantly influenced the parameters of each scenario, such as component sizing, electricity production, initial capital, NPC, and electricity purchase/sale capacity from the plant as a grid power service user to the electric utility company.

Express delivery in rural areas of China has many problems, such as high delivery cost and low efficiency. As an effective way to solve the difficulties of rural delivery, it is important to study the innovation and application of a joint distribution model. In the background, this paper takes express delivery enterprises in rural areas as the research object. First, it proposes to construct a three-level “county-town-village” joint distribution system in which e-commerce platforms participate. Next, it establishes an evolutionary game model of express delivery enterprise joint distribution alliance and solves it. Finally, the model is analyzed through numerical simulation. The results show that the distribution system of express delivery enterprises in rural areas is affected by excess returns, early input costs, operating costs, cooperation risks, penalty costs, learning and absorption capacity of enterprises and other factors. After introducing the rewards and punishments of e-commerce platforms as an independent influencing factor in the evolutionary game model, the shorter time for express companies to finally make cooperation strategies indicates that the rewards and punishments of e-commerce platforms have a positive significance in promoting the rapid development and stable operation of a rural logistics joint distribution system.

The actual problem of enterprise revenue management that requires an effective solution is considered. Revenue is the main source of cash proceeds specifically from the main enterprise activities, as well as one of the main factors affecting enterprise functioning. As a result, the amount of revenue is extremely important for the company—it must be sufficient to ensure the repayment of all expenses of the company and the formation of the required profit amount. However, the amount of revenue itself is not the only important characteristic of revenue; the revenue stability over time and the revenue receipt regularity are no less important. The purpose of this work is to develop a dynamic model of enterprise revenue management, which differs from the model known in the literature by considering the parameter of enterprise performance efficiency. The parametric method of Stochastic Frontier Analysis (SFA) is used as a method to evaluate the efficiency of an enterprise. Financial indicators are used as input and output data. The model was tested on six small business sectors of a single-industry town for the period from 2007 to 2021. Data collection was carried out using the SPARK system, which allows selecting enterprises for research by the status of the enterprise (bankrupt/operating), by the size of the enterprise (large/medium/small/micro), etc. The above calculations based on the constructed modified model have demonstrated the possibility of using the enterprise’s revenue management with the desired rate of change and with the work efficiency parameter.

In contrast with many other sectors of the Russian economy, there is low market concentration in the forest industry and, consequently, a large number of relatively small enterprises scattered throughout the world’s largest country. In many cases, logging or woodworking companies are the only or key employers in sparsely populated areas, making them important sources of the social and economic stability of small towns and rural settlements. In 2022, Russian forest companies faced dramatic barriers to international trade, which led to the suspension of production with the risk of further layoffs. Thus, the issue of social and economic importance of the forest business in Russia has gained additional sounding. This paper aims to estimate the decline in revenues and the number of employees in forestry companies in Asian Russia because of sanctions. Based on corporate accounting reports, we have generated a dataset covering 4675 forest industry companies in Asian Russia. We use quantile regression to estimate the impact of the number of employees on revenue. All companies were divided into quartiles by revenue and into 6 groups by type of economic activity. A significant differentiation of the return on the number of employees depending on the type of activity and the volume of firms’ revenues was found. Estimates of potential losses of companies during labor force reduction were obtained, which would be 1.2%–3.6% of revenue for a company from Q1, 2.2%–6.6% of revenue for Q2 and 2.7%–8.1% of revenue for Q3. The results clearly demonstrate that forest companies might be very interested in retaining a workforce, even if an opportunistic drop in product demand creates a financial shortfall. Policy makers should take this into account when shaping instruments to support the industry. Full article

Since the mid-nineteen century, when the first mining companies were established in the region of Antofagasta to extract saltpeter, mining managers and civil authorities have always had to face a number of problems to secure a water supply sufficient for the development of industrial activities and society. The unique features of the region, namely the scarcity of rainfall, the high concentration of arsenic in freshwaters and the increasing pressure of the mining sector, have made the supply of drinking water for local communities a challenge. In the 1950s, the town of Antofagasta experienced a serious drinking water crisis. The 300 km long aqueduct starting from the Toconce catchment, opened in 1958, temporarily ended this shortage of drinking water but created an even more dramatic problem. The concentration of arsenic in the water consumed by the population had grown by approx. ten times, reaching the value of 0.860 mg/L and seriously affecting people’s health. The water treatment plants (WTPs) which were installed starting from the 1970s in the region (namely the Old and New Salar del Carmen in Antofagasta and Cerro Topater in Calama, plus the two recent desalination plants in Antofagasta and Tocopilla), have ensured, since 2014, that the drinking water coverage in the urban areas was practically universal (>99.9%). However, the rural areas have continued to experience significant shortcomings regarding their capacity to ensure the quality and continuity of the water supply service in the long run. Presently, approx. 42% of the rural population of the region of Antofagasta does not have a formal supply of drinking water. The recent amendments to the Chilean Water Code (March 2022) and the interventions carried out in the framework of the Agua Potable Rural (APR) program were intended to reduce the socio-ecological inequalities due to the lack of drinking water in the semi-concentrated and isolated rural population.
