A Connectivity Metrics-Based Approach for the Prediction of Stress-Dependent Fracture Permeability
Authors: Deng Qinglin , Shang Xueyi , He Ping
Published: February 2024

Rapid and accurate assessment of fracture permeability is critical for subsurface resource and energy development as well as rock engineering stability. Fracture permeability deviates from the classical cubic law under the effect of roughness, geological stress, as well as mining-induced stress. Conventional laboratory tests and numerical simulations are commonly costly and time-consuming, whereas the use of a connectivity metric based on percolation theory can quickly predict fracture permeability, but with relatively low accuracy. For this reason, we selected two static connectivity metrics with the highest and lowest prediction accuracy in previous studies, respectively, and proposed to revise and use them for fracture permeability estimation, considering the effect of isolated large-aperture regions within the fractures under increasing normal stress. Several hundred fractures with different fractal dimensions and mismatch lengths were numerically generated and deformed, and their permeability was calculated by the local cubic law (LCL). Based on the dataset, the connectivity metrics were counted using the revised approach, and the results show that, regardless of the connectivity metrics, the new model greatly improves the accuracy of permeability prediction compared to the pre-improved model, by at least 8% for different cutoff aperture thresholds.

Published: February 2024

Breast cancer is the most frequently diagnosed female cancer worldwide. Environmental contaminant exposure is suspected to be crucial, but the broad-spectrum communal properties that these suspected contaminants all share remain to be explored, especially in source and drinking water. In this work, we focused on the Pearl River Basin, which has the highest breast cancer incidence and mortality in China, and hypothesized that the breast cancer risk in this area is associated with its water source. Our objective was to resolve the possible communal properties that are associated with breast cancer from water mixture extracts of source and drinking water and to identify the key drivers by utilizing the latest epidemiology data, performing an exhaustive water toxicological and chemical characterization, and combining partial least-squares path statistics modeling (PLS-PM). We proposed a path for a drinking water-toxicity-induced breast cancer risk and confirmed its association with estrogen-receptor- and thiol-depletion-relevant mechanisms. The breast cancer incidence risk was associated with water-mixture-promoted mammalian cell proliferation (i.e., estrogenic effect), while the mortality risk was associated with a greater thiol depletion (i.e., oxidative stress). Endocrine-disrupting chemicals (EDCs) and dissolved organic matter (DOM) from anthropogenic sources in drinking water are key drivers for estrogenic effects and oxidative stress, respectively. The PLS-PM standardized effects of the DOM and EDCs in treated water on the breast cancer incidence and mortality were −0.07 and 0.31, and 0.35 and 0.31, respectively, further revealing that EDCs strongly influence the incidence risk, whereas the mortality risk resulted from the joint effects of EDCs and DOM. This study clearly shows an association between the breast cancer risk and drinking water toxicity in a high-prevalence area of China, broadening the future perspectives for water-contaminant-specific breast cancer prevention research.
A Critical Review of Existing Methods to Evaluate the Performance of Nature-Based Solutions (NBS) on Commercial Roofs (CR) to Mitigate Urban Flooding
Authors: Dabas Maha , Molleti Sudhakar
Published: February 2024

The intensity and frequency of extreme rainfall events have increased in North America and the world due to climate change. Extreme rainfall events, characterized by a heavy volume of rainfall in a short duration, have triggered the onset of urban flash floods. Over the years, flash flooding has been reported in different cities in Canada, which resulted in many losses. Subsequently, different green roofing systems have been adopted to control urban stormwater runoff as part of Nature-Based Solutions (NBS) to mitigate urban flood and build a flood-resilient city. Currently, no specific widely recognized standard or code is dedicated to determining the hydrological performance of green roofs as a whole system. Moreover, there are no test protocols to regulate the design of green roof systems in the market. A comprehensive literature review examines existing research methods adopted to evaluate influencing parameters affecting the hydrological performance of NBS-CR. The results indicate several limitations in experimental and field investigations. Consequently, to address these limitations, it is essential to formulate a multi-functional work plan to develop a standardized test method that can become a common platform for the roofing industry to test and quantify the hydrological performance of their systems.

Published: February 2024

Dissolved oxygen (DO) concentration is a pivotal determinant of water quality in freshwater lake ecosystems. However, rapid population growth and discharge of polluted wastewater, urban stormwater runoff, and agricultural non-point source pollution runoff have triggered a significant decline in DO levels in Lake Erie and other freshwater lakes located in populated temperate regions of the globe. Over eleven million people rely on Lake Erie, which has been adversely impacted by anthropogenic stressors resulting in deficient DO concentrations near the bottom of Lake Erie’s Central Basin for extended periods. In the past, hybrid long short-term memory (LSTM) models have been successfully used for the time-series forecasting of water quality in rivers and ponds. However, the prediction errors tend to grow significantly with the forecasting period. Therefore, this research aimed to improve the accuracy of DO forecasting models by taking advantage of Lake Erie’s real-time water quality (water temperature and DO concentration) monitoring network to establish temporal and spatial links between adjacent monitoring stations. We developed hybrid LSTM models that combine LSTM, convolutional neuron network LSTM (CNN-LSTM), hybrid CNN with gated recurrent unit (CNN-GRU) models, and convolutional LSTM (ConvLSTM) to forecast near-bottom DO concentrations in Lake Erie’s Central Basin. These hybrid LSTM models improve their capacity to handle complicated datasets with spatial and temporal variability. These models can serve as accurate and reliable tools for forecasting DO concentrations in freshwater lakes to help environmental protection agencies better access and manage the health of these vital ecosystems. Following analysis of a 21-site Lake Erie dataset for 2020 and 2021, the ConvLSTM model emerged as the most accurate and reliable, boasting an MSE of 0.51 mg/L, MAE of 0.42 mg/L, and an R-squared of 0.95 over the 12 h prediction range. The model foresees future hypoxia in Lake Erie. Notably, the temperature near site 713 holds significance for Central Basin DO forecasting in Lake Erie, as indicated by outcomes derived from the Shapley additive explanations (SHAP).

Published: February 2024

Analyzing the spatial relationship between humans and water is crucial for regional development and water allocation schemes, particularly in the face of extreme water scarcity in the Yellow River Basin. A quantitative evaluation model of surface water resource accessibility (SWRA) has been developed, with rural settlements serving as the research unit. This model is built upon three key dimensions: topography, distance, and surface water resources within the Yellow River Basin. The results show that: (1) The SWRA range spans from 0.13 to 0.88, with an average value of 0.47 and a standard deviation of 0.05. Higher SWRA values are concentrated in the eastern and western regions, while lower values are predominantly found in the central area. (2) The gradient of SWRA across the 12 catchments, from low to high, is as follows: Sanmenxia station, Lanzhou station, Shizuishan station, Longmen station, Tongguan station, Toudaoguai station, Xiaolangdi station, Huayuankou station, Lijin station, Gaocun station, Ai Shan station, and Tangnaihai station. (3) At the city scale, the SWRA values are generally higher in the eastern areas of 10 cities, with one exception being higher in the west. Conversely, in the western areas of nine cities, the SWRA values are lower. The remaining cities exhibit SWRA values at a medium level. The correlation coefficient between primary industry gross domestic product (GDP) and SWRA is 0.271 (N = 56, Sig = 0.043, in 0.05 level, the correlation is significant), which confirms that SWRA serves as a factor influencing GDP and is appropriately designed for assessing water accessibility. Consequently, managers can utilize SWRA results to make informed decisions regarding regional development and water allocation.

Authors: Liu Qingtao , Xu Jie , Wang Qiqing , Li Wenping
Published: February 2024

Coal mines’ water inrush is one of the five major disasters that affect the safety of coal mine production. The assessment of coal mines’ water inrush is a prerequisite for preventing and controlling coal mines’ water inrush. To objectively and effectively evaluate the risk of water inrush in the coal seam roof and overcome the shortage of single assignment methods, two methods, the analytic hierarchy process and the entropy method, are used in this paper to determine each evaluation factor’s subjective and objective consequences. Game theory is applied to obtain the combined weights of each influencing factor to make up for the lack of a single assignment method. Taking the roof of Coal Seam No. 7 in mining Areas I and II of Dananhu Coal Mine No. 7 as an example, six primary evaluation indexes are created to control water inrush in the coal seam roof. The comprehensive weights of each index is determined; a vulnerability index evaluation model is established; and the results of the water inrush risk zone in the coal seam roof of Dananhu Coal Mine No. 7 are obtained using the GIS spatial analysis function. The results show that the discriminatory effects of the zoning model have a high accuracy and can provide a reference basis for future coal seam mining control work in this mine.

Published: February 2024

This study extensively explores the impact of climate change on meteorological droughts within metropolises in Iran. Focused on Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz, this research employed CMIP6 climate models under varying climate change scenarios (SSPs) to forecast severe meteorological droughts spanning the period from 2025 to 2100. The investigation utilized a diverse set of drought indices (SPI, DI, PN, CZI, MCZI, RAI, and ZSI) to assess the drought severity in each city. This study is crucial as it addresses the pressing concerns of rapidly decreasing water levels in Iran’s dams, serious declines in underground aquifers, and the compounding issues of land subsidence and soil erosion due to excessive groundwater withdrawal in the face of severe droughts. This study culminated in the generation of box plots and heatmaps based on the results. These visual representations elucidated the distribution of the drought values under different indices and scenarios and provided a depiction of the probability of severe drought occurrences until the end of the century for each city. The resulting findings serve as invaluable tools, furnishing policymakers with informed insights to proactively manage and fortify metropolitan resilience against the evolving challenges posed by a changing climate.

Authors: Wang Yingying , Lv Mouchao , Wang Wen’e , Meng Ming
Published: February 2024

In this study, experimental investigations were conducted on rectangular side weirs with different widths and heights. Corresponding simulations were also performed to analyze hydraulic characteristics including the water surface profile, flow velocity, and pressure. The relationship between the discharge coefficient and the Froude number, as well as the ratios of the side weir height and width to upstream water depth, was determined. A discharge formula was derived based on a dimensional analysis. The results demonstrated good agreement between simulated and experimental data, indicating the reliability of numerical simulations using FLOW-3D software (version 11.1). Notably, significant fluctuations in water surface profiles near the side weir were observed compared to those along the center line or away from the side weir in the main channel, suggesting that the entrance effect of the side weir did not propagate towards the center line of the main channel. The proposed discharge formula exhibited relative errors within 10%, thereby satisfying the flow measurement requirements for small channels and field inlets.

Tropical maar lakes are distinct ecosystems with unique ecological features. To comprehend, manage, and conserve these lakes, it is essential to understand their water sources, particularly groundwater, and the hydrogeochemical processes shaping their water chemistry. This research focuses on the maar lake Alchichica in central Mexico, known for harboring 18 new and endemic species and a ring of stromatolites. With groundwater discharge as the primary source, concerns arise over anthropic extraction impacts on water levels and stromatolite survival. Sampling six wells and one piezometer revealed major ion (Ca2+, Mg2+, K+, Na+, Cl−, HCO3−, SO42−) and trace element (Fe, Al3+, SiO2) concentrations. Geochemical evolution was explored through diagrams, geological sections, and inverse geochemical models using the PHREEQC code. Findings indicate groundwater evolving along controlled flow paths, and influencing chemical composition through water–rock interactions. The lake’s unique conditions, resulting from the mixing of two flows, enable stromatolite formation. Water level reduction appears unrelated to evaporation at the sampled sites, suggesting a need for a broader study in a larger area. Analyzing the maar lake’s hydrochemistry provides valuable insights into unique characteristics supporting high endemism in this ecosystem. This research enhances our understanding of groundwater’s geochemical processes and hydrogeochemical evolution in maar lakes, with potential applications worldwide.
Microalgae-Mediated Biosorption for Effective Heavy Metals Removal from Wastewater: A Review
Authors: Mahlangu Dumisane , Mphahlele Keletso , De Paola Francesco , Mthombeni Nomcebo Happiness
Published: February 2024

Environmental contamination by heavy metals poses significant threats to terrestrial and aquatic ecosystems, necessitating the development of effective remediation strategies. Conventional methods for heavy metal removal exhibit limitations, including inadequate efficiency and elevated costs. In this context, microalgae have emerged as a promising bioremediation approach due to their robust metal-binding capabilities, specifically through biosorption. This review comprehensively examines the role of microalgae in addressing heavy metal pollution, with a primary focus on their effective removal from wastewater. Microalgae offer wastewater purification potential across diverse sources and capitalize on wastewater as a growth matrix, yielding valuable bioproducts, biomaterials, and bioenergy. Their versatility allows them to thrive in various wastewaters, facilitating effective contaminant removal. This study also investigates the application of microalgae in decentralized water treatment systems (DWTSs), where the decentralized nature of these systems proves advantageous in addressing heavy metal contaminants directly at the point of generation or use. This approach holds particular significance in regions where centralized systems face obstacles due to geographical constraints, inadequate infrastructure, or financial limitations. DWTSs not only provide a decentralized solution for heavy metals removal but also prove advantageous in disaster relief scenarios and rapidly growing urban areas.

Published: February 2024

Enhancing crop production in the saline regions of the Yellow River Delta (YRD), where shallow saline groundwater is prevalent, hinges on optimizing water and salt conditions in the root zone. This study explored the effects of various physical methods on soil water and salt dynamics during the cotton growing season in these saline areas. Three approaches were tested: plastic film mulching (FM), plastic film mulching with an added compacted soil layer (FM+CL), and ridge-furrow planting (RF). The HYDRUS-2D model (Version 3.02) was used to analyze changes in soil water and salt content in the root zone over time. The results showed that subsoil compaction significantly lowered salt build-up in the root zone, especially in the top 20 cm. Film mulching was crucial for reducing water loss in the Yellow River Delta. Crop transpiration increased by 7.0% under FM and 10.5% under FM+CL compared to RF planting. Additionally, FM+CL reduced soil salinity in the top 10 cm by 11.5% at cotton harvest time compared to FM alone. The study concludes that combining film mulching with a soil compaction layer is a promising strategy for local farmers, addressing soil water retention, salt management, and boosting cotton yields.
Evaluation of the Characteristics of Pollutant Discharge in Tomato Hydroponic Wastewater (HWW) for Sustainable Water Management in Korea
Authors: Son Jinkwan
Published: February 2024

In South Korea, the use of hydroponic cultivation has been on the rise. However, this system produces a large amount of wastewater. In this study, the amount of wastewater generated by hydroponic tomato cultivation is identified, and a management plan is proposed. Based on the analysis of 103 tomato HWW samples, it was found that the electrical conductivity (EC) was 4.25 ± 1.01 dS/m, the nitrogen (N) content was 411.21 ± 122.64 mg/L, and the phosphorus (P) content was 47.74 mg/L, which caused eutrophication. Therefore, agricultural reuse and HWW treatment were proposed. Regarding the annual HWW load, 1 ha of hydroponics discharges 964.26 kg/ha of N, 111.95 of P, 937.46 of K, 795.14 of Ca, 313.83 of Mg, and 405.40 of S. The trace elements were heavy metals, which were calculated as Fe—4.03, Mn—0.77, Zn—1.08, B—2.25, Cu—0.38, and Mo—0.05 kg/ha. Since wastewater is a national source of drinking water, it needs to be collected and treated. Inter-item correlation analysis showed that most of the fertilizer components were correlated with the EC concentrations. This study can be used to determine the concentrations required for agricultural reuse and to determine the treatment capacity in HWW management.

Authors: Papciak Dorota , Domoń Andżelika , Zdeb Monika
Published: February 2024

This study assessed the impact of the method of conducting the biofiltration process on the efficiency of ammonium nitrogen removal from water in combined sorption and nitrification processes. The research was carried out on diatomite deposits using biofiltration with gravity and counter-gravity flow. The following physicochemical water parameters were controlled during the research, including ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, and dissolved oxygen. Unconventional flow turned out to be more beneficial because it allows for optimal use of the entire bed surface, natural regulation of the biofilm thickness, and maintaining constant microbiological activity of the biofilm. The automatic regulation of the biofilm thickness during water flow prevented excessive growth of dead organic matter and limited the development of heterotrophic bacteria. Biofiltration with counter-gravity flow also resulted in reduced oxygen consumption. Regardless of the flow direction used, water after the single-stage biofiltration process was characterized by an increased content of nitrite nitrogen. The introduction of the second stage of filtration made it possible to obtain water that meets the requirements for water intended for human consumption.
Pessimistic realistic or aware? – Hungarian youth’s pension expectations
Authors: Vaskövi Ágnes
Published: February 2024

Pension awareness is a specific part of financial awareness focusing on material preparation for the years of retirement at an unknown time to start in the distant future. Its starting point is dual: on the one hand, a recognition of longevity risk and, on the other hand, a proper assessment and planning of future options based on the individual’s current financial position. In this study, we wanted to survey the expectations of Hungarian university students about the state pension system, so we conducted online research with questionnaires. Three groups of questions were devised, (i) expectations of the state pension system, (ii) the generosity of the pension system, and (iii) retirement age. Pension-related expectations show that young people, in general, are quite pessimistic and regard the ageing society as the most worrying factor. Expectations about the generosity of pensions are also pessimistic, both in terms of replacement rate and the rate of state pension compared to pensioners’ total income which is estimated lower than it would actually be under the current laws. Expectations of retirement age reflect the European trends; the youth asked typically plan to retire at 65+. We also looked into regional differences and found the youth of Budapest and the Central-Hungarian region were quite negative on every issue while there were differences in other regions. Young people in Northern Hungary have a higher than average positive view of their retirement prospects. The negative attitude can be explained by the lack of transparency of the pension system and limited access to information. Also, because the reform of the state pension system is delayed in this country, respondents have major issues about its sustainability. Our findings can be important input for decision makers to shape the attitude of pension savings and retirement preparations.

Published: February 2024

Key Points

This post hoc analysis of the Tolvaptan Efficacy and Safety in Management of Autosomal Dominant Polycystic Kidney Disease and Its Outcomes 3:4 study investigated the long-term predictive potential of initial changes in eGFR.

Initial eGFR change from baseline to week 3 proved to be a significant and independent indicator of the long-term effects of tolvaptan.

No correlation was found between the initial change in eGFR and the annual rate of percent growth in total kidney volume.

Background

Tolvaptan, the only pharmaceutical treatment available for autosomal dominant polycystic kidney disease (ADPKD), reduced the rates of total kidney volume (TKV) increase and kidney function decline in patients with ADPKD in the global phase 3 Tolvaptan Efficacy and Safety in Management of Autosomal Dominant Polycystic Kidney Disease and Its Outcomes (TEMPO) 3:4 study. Since tolvaptan initiation is associated with an initial decline in the eGFR, this post hoc analysis of the TEMPO 3:4 study investigated whether initial changes in eGFR from baseline to week 3 after tolvaptan administration can predict its longer-term effects on eGFR and TKV in patients with ADPKD.

Methods

eGFR was estimated using the CKD Epidemiology Collaboration equation at baseline and up to month 36. TKV was estimated using standardized kidney magnetic resonance imaging at baseline and after 12, 24, and 36 months of tolvaptan treatment. The effect of tolvaptan on kidney function and kidney volume was evaluated by measuring changes in eGFR from week 3 and TKV from baseline up to 36 months. All 961 patients randomized to receive tolvaptan in TEMPO 3:4 were included in this analysis.

Results

Initial change in eGFR from baseline to week 3 was a significant and independent predictor of the mean rate of change in eGFR per year. By contrast, there was no association between initial change in eGFR and the rate of percent growth in TKV per year.

Conclusions

Changes in eGFR after 3 weeks of treatment are likely due to the pharmacologic effect of tolvaptan, and these initial changes are predictive of the long-term effects of tolvaptan treatment.

There is little empirical research concerning whether flipped learning can be a viable alternative to the traditional present-practice-produce class of EFL (English as a foreign language) oral/aural skills for adult learners. The present study addresses this gap by investigating the effects of flipped learning on adult learners’ improvement in EFL speaking. Twelve Korean native speakers participated in a language course comprised of 24 sessions for a three-month period (60-minute per session, 2 sessions per week); six of them were assigned to a control group where they received traditional offline lectures in the classroom while the other six participated in flipped learning. Learners with similar backgrounds and attitudinal profiles were chosen as a focus group and their achievements and classroom behaviors were compared. The results indicate that when compared in pairs of shared learner variables, students in the experimental group invariably outperformed their counterparts in the control group on both immediate and delayed post-tests. Students in the flipped classroom also demonstrated some characteristic behavioral features that were not observed in the control group, such as connecting prior and current discussions, formulating more elaborated and personalized questions, and exercising autonomy by proposing their own discussion topics.

Published: February 2024

Microplastics can accumulate in the environment and be transferred to different trophic levels, making them a concern for the aquatic food chain. As far as the researcher is aware, this study is the first to analyze microplastics in seawater and zooplankton along the eastern coastline of Phuket, Thailand, emphasizing their ecological significance. Analysis of the seawater samples identified 256 microplastic particles, with an average concentration of 52.6±21.4 and 32.6±30.3 particles L-1 for 20–300 µm and >300 µm classes, respectively. Four zooplankton species—copepod, fish larvae, bivalvia larvae, and shrimp larvae—were chosen for examination. The findings indicated that microplastics can move to higher trophic levels, and their interaction with zooplankton resulted in 26 microplastic particles among the 120 zooplankton individuals observed. This yielded an average ingestion rate of 0.22±0.57 particles per individual zooplankton, with the highest rate observed among fish larvae. The micro-Fourier Transform Interferometer (µFT-IR) analysis verified the presence of polyethylene terephthalate (PET), polyethylene (PE), polyester, urea-formaldehyde (UF), and polyamide (PA). This underscores the prevalence of these polymers in daily and human-made plastic sources, emphasizing the need to implement effective measures to address micro-plastic pollution in ecologically vital areas to safeguard marine environments.

Published: February 2024

The decrease in air quality has been a major concern in the world for decades, and it has continued to worsen with toxic gases accumulating at exponential rates. The atmosphere has been heavily polluted as a result of anthropogenic activities, and these activities were greatly reduced during the COVID-19 pandemic when a lockdown policy was imposed. The study area, Lagos, is the state in Nigeria with the highest population count, making it most susceptible to the spread of the coronavirus and, as such, having the strictest policy regulations. This study seeks to evaluate the effects of the COVID-19 lockdown policy on air quality in Lagos State. The study adopted geographic information systems (GIS) and remote sensing techniques. Goggle Earth Engine (GEE) and Sentinel 5P (S5P) TROPOMI dataset were used to obtain results for carbon monoxide (CO), sulphur dioxide (SO2), aerosols (particulate matter), and nitrogen dioxide (NO2) through JavaScript coding for the year before the lockdown (2019), the year of the lockdown (2020), and the year after the lockdown (2021). Results from the study revealed that the year 2020 had lower concentrations of aerosols and NO2, which increased in 2021 when human and vehicular activities were back to normal. SO2 and CO concen-trations were higher in the year 2020 than in year 2019 and 2021, suggesting that the COVID-19 lockdown was loosely implemented. It is recommended that policymakers invest in green technologies such as solar systems to minimize emissions, enforce strict emission standards for industries and vehicles to limit the release of air pollutants.

Abstract.     The intention to continue the family business can be influenced in particular by parents. This study discusses the influence of parental support dimensions including Instrumental Assistance (IA) and Career-related modeling (CRM) in forming the intention to continue a family business that focuses on female successors with self-efficacy as mediation. Through this research, it is expected to be able to provide the latest views, especially girls, when in the family business. The sampling technique used was a purposive sampling technique on 195 girls aged at least 18 years who had contributed to the family business. This research was tested using SmartPLS 3.0 and JASP software. Through this study, the findings of this study indicate that both Instrumental Assistance (IA) and self-efficacy play significant roles in shaping a daughter's inclination to achieve success within the context of a family business. Unlike the previous Career-Related Modeling (CRM) based on specific studies indicate that self-efficacy does not serve as a mediating factor in the relationship between Career-Related Modelling and a daughter's intention to succeed in the family business.

L’urbanistica come strumento di tutela dei paesaggi rurali storici
Authors: Agostini Ilaria
Published: February 2024

Sul finire degli anni Settanta, l’intensità delle trasformazioni territoriali rende “drammaticamente urgente” – come ricorda Gian Franco Di Pietro  – l’individuazione, in Toscana, di uno strumento urbanistico indirizzato alla tutela del paesaggio. È ascrivibile a tale urgenza il precoce capitolo di pianificazione dei paesaggi rurali storici toscani, tema su cui ci soffermeremo, di pochi anni precedente la definizione formale della pianificazione ‘paesistica’ avvenuta a partire dal 1985 con la cosiddetta legge Galasso.
I primi piani urbanistici generali 1963-1986
Authors: Carbone Carlo
Published: February 2024

L’impegno nel progetto di piani urbanistici generali di Gian Franco Di Pietro ha luogo nella fase di consolidamento della crescita economica e demografica degli anni Cinquanta e di maturazione del grande squilibrio fra le zone di sviluppo e quelle di abbandono, con la vigenza della sola L.1150/42, quando il PRG non era obbligatorio né doveva estendersi all’intero territorio comunale e veniva considerato prevalentemente come strumento per indicare le sole aree destinate all’espansione.
GRAMSCI E O ENCONTRO COM O MUNDO ÁRABE
Authors: Manduchi Patrizia , Marchi Alessandra
Published: February 2024

O artigo resulta de pesquisas, na perspectiva gramsciana, sobre a história dos países islâmicos e de atividades do Laboratório de Estudos Internacionais Gramsci da Universidade de Cagliari (Gramsci Lab), que reconstroem as etapas e os desenvolvimentos de um processo que, ao longo dos anos, possibilitou a penetração do pensamento do autor dos Cadernos do Cárcere no mundo árabe. Realidades nas quais o tema da tradutibilidade filosófica assume um indubitável interesse político, devido à incidência de contradições, conflitos e processos revolucionários desencadeados pela dialética entre o legado colonial e o presente desses países e as lutas dos povos dessa parte do mundo, pela emancipação dos paradigmas da civilização ocidental, impostos à força ao longo dos séculos.
HEGEMONIA E BLOCO HISTÓRICO
Authors: Douvan Alexandre , Simão Pontes Felipe
Published: February 2024

Este artigo objetiva uma análise do conceito de hegemonia em Gramsci a partir das contribuições de diferentes autores que geraram influência sobre a teorização gramsciana com a problematização da interpretação de Laclau e Mouffe (2015) sobre o fim dos conflitos pela hegemonia quando consumada a unificação do bloco histórico. Para a análise, retomam-se as matrizes históricas, significados e modificações no sentido do conceito, tomando-se como ponto de partida a cunhagem grega do termo, sua retomada no círculo da social democracia russa e, então, a crucial contribuição de Lênin, as interpretações de Trotski, Rosa Luxemburgo e outros autores que de uma forma ou de outra enriqueceram o conceito até a interpretação aprofundada de Gramsci. Estruturados esses elementos, propõe-se uma leitura distinta daquela empreendida por Laclau e Mouffe sobre a auto-anulação do conceito no momento de unificação do bloco histórico.
