Published: June 2024

This study examined injuries sustained by a six-year-old child dummy in a numerical dolly rollover crash using a Toyota Yaris 2010. A harmonic dynamic system (HDS) composed of spring, dampers, and masses with a Low Back Booster (LBB) is denominated as HDS-LBB model. The HDS-LBB was designed to allow damping movements along three Cartesian axes (X, Y, Z) to reduce the energy transferred to the child by a motor vehicle accident and avoid a high injury risk. The HDS-LBB incorporates springs into the vertical axis to decrease the vertical movement during the rollover. The numerical analysis was conducted using LS-Dyna® R12.1 version during an interval of 1 s, and the boundary conditions were set by the Federal Motor Vehicle Safety Standard (FMVSS) 213 for child restraint recommendations and the FMVSS 208 for a dolly rollover procedure. Data on head and thorax decelerations, neck flexion-extension, and thoracic deflection were acquired at a rate of 1 ms. The injury values obtained by the HDS-LBB were compared with the injury values by another configuration denominated LBB-ISOFIX to assess the effectiveness of the model proposed. The results show a higher peak injury value in the neck and thorax because of seatbelt displacement across the child’s shoulder. Nevertheless, despite this seatbelt behavior, the injuries sustained remained below the Injury Assessment Reference Values (IARVS).
Coming of Age While Challenging Borders: Networks of Solidarity and Resistance of Swedish-Afghan Youths on the Move in Europe
Authors: Rebelo Dora
Published: June 2024

This article examines the strategies of resistance enacted by an informal network of solidarity comprised of Afghan youths on the move in Europe and their Swedish allies. In 2015, thousands of Afghan children fleeing from the Taliban regime arrived in Europe as unaccompanied minors. Many have been hosted in Sweden and lived there for several years, until coming of age. Reaching 18 years prompted a series of consecutive losses, as the Swedish state limited their opportunities to remain in the country or even illegalized them. Subjected to threats of detention, deportation, and ill treatment, many Afghan youths re-escaped into other European countries, crafting networks of informal solidarity to help them resist border violence. This article is based on an ethnographic study that delves into the lived experiences of four Afghan youths who lived in Lisbon between February 2019 and February 2020, particularly focusing on the journey of Ahmed, a young man of Hazara ethnicity. The empirical data shed light on the solidarity enactments that enhanced the youths’ resistance in hostile environments, inviting reflection on the impacts of the European border regime and the importance of agency, care, and political contestation.
Prison and Love: The Role of Affection and Rehabilitative Actions in Reducing Recidivism and Beyond
Authors: Cataldi Laura , Cataldi Silvia
Published: June 2024

This study investigates the protective role of emotional relationships and rehabilitative actions in reducing recidivism within the prison context. Data were collected from three Italian prisons as part of the European project “Calypsos”. This study examines the role of love across its various expressions and components in the social reintegration of inmates, exploring how family ties, educational programs, and employment opportunities contribute to their well-being and socio-affective regeneration. Descriptive analyses and multiple linear regression were used to assess the impact of these factors on recidivism. The results indicate that stable family relationships, positive interactions with teachers, and meaningful work experiences significantly reduce the likelihood of reoffending. The findings highlight the necessity of policies supporting the maintenance of emotional bonds and the provision of educational and vocational training within prisons. This study concludes that integrating these elements into rehabilitation strategies can improve inmate outcomes, reduce recidivism, and enhance social cohesion. Finally, the article identifies love as a performative right as a future research direction.

Published: June 2024

Globally, rural conditions are in states of change. They are often highly vulnerable to climate and environmental change, extreme weather events, conflict, socio-economic changes, inequalities, and demographic changes. These changes are putting stress on rural areas, which rely upon agriculture and natural resources for their livelihoods and are often the foundation of national economies. Communication for development (C4D) has played an important role in addressing these challenges. Its thinking is broadly consistent with rural development goals—indeed, the roots of C4D come in part from rural development and agricultural extension. Communication for development (C4D) was defined by the World Congress on Communication for Development as “…a social process based on dialogue using a broad range of tools and methods. It also seeks change at different levels, including listening, building trust, sharing knowledge and skills, building policies, debating, and learning for sustained and meaningful change. It is not public relations or corporate communications”. However, after decades of action to address these interrelated rural development challenges, much remains to be done. This paper critically considers the following: What does inclusive rural development mean now, in light of environmental change, and how does this affect the conceptualisation and practice of C4D? This was done by using three countries as case studies: Malawi, Ukraine, and the Philippines. Each of these countries represented contrasting challenges and opportunities for rural development and environmental change, with lessons from their experiences shedding insight into the communication for development thinking.
Sustainable Cement Stabilization of Plastic Clay Using Ground Municipal Solid Waste: Enhancing Soil Properties for Geotechnical Applications
Authors: Baldovino Jair Arrieta , Nuñez de la Rosa Yamid E. , Namdar Abdoullah
Published: June 2024

The unconfined compressive strength (qu) weakness of low-compressibility clay (CL) reduces its structural safety. As part of the present study, waste glass powder (WGP) was mixed with Portland cement to improve the geotechnical properties of clayey soil, thus contributing to sustainability through the recycling of municipal waste. Based on the stiffness and chemical composite of WGP and cement, the adopted mixing ratio of the mixed soil was 10% and 20% WGP and 3% and 6% cement. The soil mixing ratio was selected and tested considering the percentage of the cement, WGP, water/cement ratio, dry unit weight, porosity of the specimen, and curing times of 7 days and 28 days. SEM-EDS tests were conducted to examine the impact of raw materials on the microstructural mixed soil. The results from SEM-EDS show that the cement–WGP–CL mixture caused different degrees of cementation and bonding products. Modifying multiple layers of water in the particle of the clay surface led to the enhancement of the interaction of the interlayer of hydrated clay, achieving the best unconfined compressive strength and stiffness of the designed specimen. From the viewpoint of unconfined compressive strength and stiffness enhancement, blending content of 20% WGP and 6% cement and dry unit weights compaction was recommended for stabilizing CL. The process of qu and stiffness improving CL involved an optimized mixing ratio and particle densification reaction efficiency. The soil’s qu and stiffness were predicted using ANN (artificial neural networks) and the porosity/cement index was predicted based on the experimental results.

Published: June 2024

Urban vegetation has an essential role in maintaining the hydrological and energy balance. These processes in urban areas have been long overlooked due to the fragmentation and uneven feature of land use and vegetation distribution. Recent advances in remote sensing and the ease of data acquisition have allowed a more precise mapping of vegetation and land cover, making it possible to simulate the above processes at micro scales. This research selects a small typical residential catchment in Japan as the study area and the purpose of this research is to investigate the impact of urban vegetation on mitigating urban runoff and the heat island effect. The remote-sensed Normalized Difference Vegetation Index (NDVI) data were used to represent vegetation spatial distribution and seasonal variation. A single layer canopy model and the Storm Water Management Model were coupled to simulate interception, evapotranspiration, and runoff generation processes. The effects of vegetation amount and landscape patterns on the above processes were also considered. The results showed that the coupled model had a satisfactory performance in the modeling of these processes. When the vegetation amount was set to 1.4 times its original value, the summer total runoff had a 10.7% reduction and the average surface temperature had a 2.5 °C reduction. While the vegetation amount was 0.8 times its original value, the total runoff increased by 6%, and the average surface temperature in summer increased by 1.5 °C. The combination of green roof and dense street trees showed the best mitigation performance among the different landscape patterns. The results of this study could be used as a reference for future green infrastructure development in areas with similar climate and vegetation characteristics.
Sustainable Waste Management in Orthopedic Healthcare Services
Authors: Moldovan Flaviu , Moldovan Liviu
Published: June 2024

It is estimated that globally medical surgical specialties, including orthopedics, produce large amounts of hospital waste. However, the possibilities of recycling materials are not well highlighted. Orthopedic hospitals can collect larger volumes of recyclables that could be kept out of landfills. The general objective of this study is to identify the categories and related amounts of waste and recyclable materials produced by the main types of medical interventions in orthopedics. The specific objective is to evaluate the amounts of waste produced in the preoperative and intraoperative periods, but also their recycling potential. For one month, we analyzed eight types of orthopedic medical interventions, of which five were surgical and three were nonsurgical. These were performed at the County Emergency Clinical Hospital of Targu Mures in Romania. For surgical interventions, the waste was collected separately in the preoperative and intraoperative periods. Waste was divided into recyclable, nonrecyclable, and biological categories. The waste bags were weighed with a portable scale. The main results are the average amounts of recyclable waste produced per case in the eight types of medical interventions. The secondary results show the average amounts per case of nonrecyclable, biological, and total waste. To test for statistically significant differences between the types of medical interventions, we performed an analysis of variance. Seventy-four cases were included in the study. An amount of 466.2 kg of waste was collected, with an average mass of 6.3 kg per case. During the preoperative period, 130.3 kg of waste was produced, of which 78% was recyclable. During the intraoperative period, 303.8 kg of waste was produced and only 11% was recyclable. Trauma surgery produced the largest amount of waste, followed by arthroplasty. A quarter of orthopedic waste is recyclable, and the greatest potential for recycling is preoperative waste, which can be effectively recycled at three-quarters. Through effective recycling programs, the ecological footprint of orthopedic–traumatology interventions can be reduced.
The Moderating Role of ESG Administration on the Relationship between Tourism Activities and Carbon Emissions: A Case Study of Basic Local Governments in South Korea
Authors: Oh Heekyun
Published: June 2024

This study examines the impact of tourism activities (TA) on carbon emissions (CE) in South Korea and investigates how ESG (environmental, social, and governance) administration power moderates these relationships. To explore four research areas—the relationship between TA and CE; variations across three years (2019–2021); the moderating effect of ESG policies; and the influence of control variables—MIMIC models were employed using secondary data from credible national institutions. The main results across the years and ESG groups (high vs. low) are as follows: (1) The positive influence of individual TA on CE ranked as food and beverage > shopping > recreation > accommodation, with no differences across the years or ESG groups. (2) ESG administration alleviated the carbon-emitting effects of TA, with significant moderation in 2019 and 2021, but not in 2020 (particularly, the effect sizes of TA were greater in low ESG groups). (3) Although tourism development stimulates TA more strongly in the high ESG groups, the CE induced by TA is significantly mitigated by ESG administrative support, resulting in smaller effects than those observed in the low groups. (4) The latter part covers diverse discussions on the influence of control variables—such as infection safety, atmospheric pollution, tourism development, income levels, green space, and local population.

Published: June 2024

China’s new-type urbanization has been instrumental in fostering high-quality economic and social progress. This research explores the impact and underlying mechanisms of the new-type urbanization policy on urban green total factor productivity (GTFP) by analyzing a sample of 165 Chinese prefecture-level cities from 2009 to 2020. Utilizing the difference-in-differences (DID) approach, the study uncovers several key findings: (1) compared to non-pilot areas, the new-type urbanization policy significantly boosts urban GTFP by 43.5%, supporting a shift towards more sustainable and eco-friendly urban growth; (2) the analysis of impact mechanisms indicates that these policies enhance urban GTFP through technological innovation and environmental regulation; and (3) the urban agglomeration model test reveals that being part of an urban agglomeration amplifies the effects of the new-type urbanization policy on GTFP. These results underscore the significance of these policies in driving sustainable and high-quality urban development in China, offering valuable insights for policymakers to formulate and implement effective urbanization strategies.

Authors: İnce Melike Nur , Taşdemir Çağatay
Published: June 2024

Global economic growth, marked by rising GDP and population, has spurred demand for essential goods including furniture. This study presents a comprehensive demand forecasting analysis for retail furniture sales in the U.S. for the next 36 months using Multiple Linear Regression (MLR) and Holt–Winters methods. Leveraging retail sales data from 2019 to 2023, alongside key influencing factors such as furniture imports, consumer sentiment, and housing starts, we developed two predictive models. The results indicated that retail furniture sales exhibited strong seasonality and a positive trend, with the lowest forecasted demand in April 2024 (USD 9118 million) and the highest in December 2026 (USD 13,577 million). The average annual demand for 2024, 2025, and 2026 is projected at USD 12,122.5 million, USD 12,522.67 million, and USD 12,922.17 million, respectively, based on MLR, while Holt–Winters results are slightly more conservative. The models were compared using the Mean Absolute Percentage Error (MAPE) metric, with the MLR model yielding a MAPE of 3.47% and the Holt–Winters model achieving a MAPE of 4.21%. The study’s findings align with global market projections and highlight the growing demand trajectory in the U.S. furniture industry, providing valuable insights for strategic decision-making and operations management.

Authors: Leng Zheng , Zhou Changzhi , Hou Hong , Wang Junhuan
Published: June 2024

The adsorption of Sb(V) and As(V) onto iron-loaded gasification slag composite material (Fe-GFS), as well as the possible mechanisms, was investigated. Batch experiments showed that in a single system, Fe-GFS sorbed As(V) to a greater extent than Sb(V) with the maximum adsorption capacity (pH 3.0) of 34.99 mg/g (0.47 mmol/g), while that of Sb(V) was 27.61 mg/g (0.23 mmol/g). In the composite system, the presence of low concentrations of Sb(V) reduced the adsorption efficiency of Fe-GFS for As(V), while the presence of high concentrations of Sb(V) actually promoted the adsorption of As(V). The presence of As(V) consistently inhibited the adsorption of Sb(V) by Fe-GFS. Compared to Fe-GFS, new peaks appeared in the FTIR spectra after adsorption, indicating the presence of Sb-O and As-O bonds on the surface after adsorption. XPS results showed that the adsorption of As(V) and Sb(V) led to a decrease in Fe-OH bonds, with a more significant decrease in Fe-OH bonds observed after the adsorption of As(V), indicating a stronger affinity of Fe-GFS for As(V) compared to Sb(V). Our results suggest that Fe-GFS is an efficient adsorbent with great potential for applications in water containing As(V) and Sb(V).

Authors: Abu-Saleem Mohammed , Vieira Horacio Santana , Borges Luiz Henrique Campos
Published: June 2024

In this paper, we examine the role played by topology, and some specific boundary conditions as well, on the physics of a higher-dimensional black hole. We analyze the line element of a five-dimensional non-extremal Reissner–Nordström black hole to obtain a new family of subspaces that are types of strong retractions and deformations, and then we extend these results to higher dimensions in order to deduce the relationship between various types of transformations. We also study the scalar field perturbations in the background under consideration and obtain an analytical expression for the quasibound state frequencies by using the Vieira–Bezerra–Kokkotas approach, which uses the polynomial conditions of the general Heun functions, and then we discuss the stability of the system and present the radial eigenfunctions. Our main goal is to discuss the physical meaning of these mathematical applications in such higher-dimensional effective metric.
Why Foot-and-Mouth Disease-Free with Vaccination Should Be Equivalent to Foot-and-Mouth Disease-Free without Vaccination
Authors: Moura Pedro , Kihm Ulrich , Schudel Alejandro , Bergmann Ingrid , Buholzer Patrik
Published: June 2024

Foot-and-Mouth Disease (FMD) is still one of the most relevant animal diseases and remains of global concern. The World Organization for Animal Health (WOAH) has specified two sanitary statuses that assure freedom from FMD: a country or zone can be free from FMD either with or without vaccination. To obtain either of the two statuses, absence of virus circulation must be shown. The standards set by WOAH are used for trade negotiations. During recent decades, different tools and approaches were developed to control FMD, including vaccines, diagnostics, and the Progressive Control Pathway for FMD. These tools improved over time, and nowadays high-quality, reliable vaccines and specific diagnostics are available to efficiently control and detect the infection, even in vaccinated populations. Due to these improvements, it is no longer justifiable to treat the two FMD-free statuses differently. The distinction between the statuses provides wrong incentives and tempts countries to take increased risks by stopping vaccination to improve their trade conditions, which can have potentially devastating consequences. The decision to stop vaccination should only be made on the basis of a careful and comprehensive analysis of the local and regional epidemiological situation. This paper presents the perspective that member countries and WOAH should recognize the two FMD-free statuses as equivalent.
Prevalence of Near-Vision-Related Symptoms in a University Population
Authors: Gomes Jessica , Franco Sandra
Published: June 2024

The university population has high visual demands. It is therefore important to assess the prevalence of symptoms in these subjects, which may affect their academic performance. In this cross-sectional study, a randomized sample of 252 subjects from a university answered the Convergence Insufficiency Symptom Survey (CISS) questionnaire. In addition, questions were asked about blurred vision during and after near tasks, the number of hours per day spent in near vision, and whether or not they wore glasses. Furthermore, 110 subjects underwent an eye exam, including a refraction and accommodation assessment. The mean age of the subjects was 28.79 ± 11.36 years, 62.3% reported wearing glasses, and on average 7.20 ± 2.92 hours/day was spent in near vision. The mean of the CISS score was 18.69 ± 9.96, and according to its criteria, 38% of the subjects were symptomatic. Some symptoms were significantly (p < 0.05) more frequent in subjects wearing glasses. Accommodative dysfunctions were present in 30.9% of the subjects, the most common being insufficiency of accommodation. We emphasise the importance of assessing symptomatology during the clinical examination in this group of subjects, as they spend many hours a day in near vision, as well as assessing accommodation, binocular vision, and the ergonomic work environment, which may be at the origin of the symptoms, in addition to the need to wear glasses.

Published: June 2024

The natural hydrological cycle of basins has been significantly altered by climate change and human activities, leading to considerable uncertainties in attributing runoff. In this study, the impact of climate change and human activities on runoff of the Ganjiang River Basin was analyzed, and a variety of models with different spatio-temporal scales and complexities were used to evaluate the influence of model choice on runoff attribution and to reduce the uncertainties. The results show the following: (1) The potential evapotranspiration in the Ganjiang River Basin showed a significant downward trend, precipitation showed a significant upward trend, runoff showed a nonsignificant upward trend, and an abrupt change was detected in 1968; (2) The three hydrological models used with different temporal scales and complexity, GR1A, ABCD, DTVGM, can simulate the natural distribution of water resources in the Ganjiang River Basin; and (3) The impact of climate change on runoff change ranges from 60.07% to 82.88%, while human activities account for approximately 17.12% to 39.93%. The results show that climate change is the main driving factor leading to runoff variation in the Ganjiang River Basin.
Carbon Emission Reduction of Reclaimed Water Use Substitution for Inter-Basin Water Transfer and Sustainability of Urban Water Supply in Valley Area
Authors: Ma Nian , Xu Yongxin
Published: June 2024

Urbanization confronts the dual challenges of water scarcity and environmental degradation, prompting the exploration of diverse water sources for mitigating these impacts. Inter-basin water transfer (IBWT) has emerged as a solution to balance urban water demand and supply in areas with local water shortages. While IBWT can deliver high-quality water over long distances, it is costly, often contributing significantly to carbon emissions. Reclaimed water use (RWU) presents a promising alternative to address this dilemma. In this paper, a valley region of Chongqing municipality in Southwest China, which is confronted with water and environmental risks resulting from rapid urbanization, was explored and discussed as a case study to assess the potential impact of RWU on reducing carbon emissions as compared to IBWT. A method of accumulative accounting was adapted to calculate and sum up carbon emission intensities at various stages, revealing that the operational carbon emission intensities of IBWT and RWU are 0.7447 KgCO2/m3 and 0.1880 KgCO2/m3, respectively. This indicates that RWU substitution can reduce carbon emissions by 0.5567 KgCO2/m3 or 75%. This paper further elucidates the mechanism behind carbon emission reduction, highlighting the energy-saving benefits of using reclaimed water locally without recourse to extensive transportation or elevation changes. Additionally, this result presents three scenarios of reclaimed water use, including urban miscellaneous water, river flow replenishment, and agricultural irrigation in relation to their substitution effects and environmental impacts. Estimates of carbon emission reductions from reclaimed water use were projected at the planned scale, with the maximum potential of reclaimed water utilization predicted. Finally, this paper proposes an enhanced strategy to identify and prioritize factors affecting reclaimed water utilization and the effect of carbon emission reduction. This paper aims to facilitate the establishment of a robust legal, institutional, and managerial framework while fostering interdisciplinary and cross-sectoral cooperation mechanisms in valley urban areas. The methodology employed can be universally applied to other regions grappling with severe water stress, thereby facilitating endeavors toward carbon reduction and contributing significantly to the attainment of water sustainability.

Data on state-of-the-art battery electric vehicles are crucial to academia; however, these data are not published due to non-disclosure policies in the industry. As a result, simulation models and their analyses are based on assumptions or insider information. To fill this information gap, we present a comprehensive analysis of the electric powertrain of a Tesla Model 3 Standard Range Plus (SR+) from 2020 with lithium iron phosphate (LFP) cells, focusing on the overall range. On the vehicle level, we observe the resulting range in multiple test scenarios, tracing the energy path from source to sink by conducting different test series on the vehicle dynamometer and through alternating current (AC) and direct current (DC) charging measurements. In addition to absolute electric range tests in different operating scenarios and electric and thermal operation strategies on the vehicle level, we analyze the energy density and the power unit’s efficiency on the component level. These tests are performed through procedures on the chassis dynamometer as well as efficiency analysis and electric characterization tests in charge/discharge scenarios. This study includes over 1 GB of attached measurement data on the battery pack and vehicle level from the lab to the real-world environment available as open-source data.

Published: June 2024

Purpose: As introduced, multimodal pain management bundle for ileostomy reversal may be considered to reduce postoperative pain and hospital stay. The aim of this study was to evaluate clinical efficacy of perioperative multimodal pain bundle for ileostomy.Methods: Medical records of patients who underwent ileostomy reversal after rectal cancer surgery from April 2017 to March 2020 were analyzed. Sixty-seven patients received multimodal pain bundle protocol with ileostomy reversal (group A) and 41 patients underwent closure of ileostomy with conventional pain management (group B).Results: Baseline characteristics, including age, sex, body mass index, American Society of Anesthesiologists classification, diabetes mellitus, and smoking history, were not significantly different between the groups. The pain score on postoperative day 1 was significant lower in group A (visual analog scale, 2.6 ± 1.3 vs. 3.2 ± 1.2; P = 0.013). Overall consumption of opioid in group A was significant less than group B (9.7 ± 9.5 vs. 21.2 ± 8.8, P < 0.001). Hospital stay was significantly shorter in group A (2.3 ± 1.5 days vs. 4.1 ± 1.5 days, P < 0.001). There were no significant differences between the groups in postoperative complication rate.Conclusion: Multimodal pain protocol for ileostomy reversal could reduce postoperative pain, usage of opioid and hospital stay compared to conventional pain management.
Preoperative localization of potentially invisible colonic lesions on the laparoscopic operation field: using autologous blood tattooing

Published: June 2024

Purpose: Preoperative colonoscopic (POC) localization is recommended for patients scheduled for elective laparoscopic colectomy for early colon cancer. Among the various localization method, POC tattooing localization has been widely used. Several dyes have been used for tattooing, but dye has disadvantages, including foreign body reactions. For this reason, we have used autologous blood tattooing for POC localization. This study aimed to evaluate the safety and efficacy of the autologous blood tattooing method.Methods: This study included patients who required POC localization of the colonic neoplasm among the patients who were scheduled for elective colon resection. The indication for localization was early colon cancer (clinically T1 or T2) or colonic neoplasms that could not be resected endoscopically. POC autologous blood tattooing was performed after saline injection, and 2 hemoclips were applied.Results: A total of 45 patients who underwent autologous blood tattooing and laparoscopic colectomy were included in this study. All POC localization sites were visible in the laparoscopic view. POC localization sites showed almost perfect agreement with intraoperative surgical findings. There were no complications like bowel perforation, peritonitis, hemoperitoneum, and mesenteric hematoma.Conclusion: Autologous blood is a safe and effective agent for localizing materials that can replace previous dyes. However, a large prospective case-control study is required for the routine application of this procedure in early colon cancer or colonic neoplasms.

Complete mesocolic excision and central vascular ligation with D3 lymphadenectomy are important surgical principles for improving oncological outcomes in colon cancer. The cranial-first approach is a colonic mobilization–first approach to radical right hemicolectomy, which has several advantages, including early feasibility assessment, safe dissection from surrounding organs, preestablished inferior margin of lymph node dissection, and revelation of the tangible anatomy of the tributaries of the gastrocolic trunk. This video demonstrates the cranial-first approach to radical right hemicolectomy in a 66-year-old man with locally advanced cecal cancer.
¿Qué significa apoyar a la democracia? La psicología política de la erosión democrática en América Latina
Authors: Sarsfield Rodolfo
Published: June 2024

La literatura sobre opinión pública que investiga el apoyo a la democracia ha adolecido de un déficit fundamental: no ha explorado qué quiere decir que un ciudadano exprese, en situación de encuesta, que prefiere un gobierno democrático. Estudiar los significados asociados a la democracia podría explicar la presencia de electorados que responden apoyar a sus regímenes democráticos y que, al mismo tiempo, dan su respaldo electoral a líderes de dudosas credenciales democráticas como ocurre en varios países de América Latina. Dada esta paradoja, en este trabajo se indaga qué concepciones de democracia circulan entre los ciudadanos de la región. Los resultados muestran una amplia presencia de nociones sobre la democracia que son iliberales y poco proclives a los mecanismos de pesos y contrapesos. Así, el estudio encuentra amplios sectores de los latinoamericanos a favor de formas de democracia iliberal y formas de democracia delegativa. Tales significados asociados a la democracia podrían representar la psicología política de la erosión democrática observada en varias naciones de Latinoamérica.

This article explores the multifaceted nature of communicative competence, discuss its key components, and examine strategies for developing and enhancing this vital skill based on the survey conducted among English language learners. Through a deeper understanding of communicative competence, learners can unlock the full potential of their language abilities and navigate the complexities of our interconnected world with confidence and proficiency. The analysis of an online survey among first-year students provides insights into gender distribution, English proficiency levels, communication skills, and cultural awareness. A significant gender disparity is evident, with females comprising 83% of participants. Regarding English proficiency, the majority perceive themselves as intermediate, with smaller proportions identifying as pre-intermediate, beginner, or advanced. While confidence in overall communication skills is high, specific challenges exist in grammar, speaking, and writing. Limited engagement in English conversations outside formal settings indicates a need for increased practice opportunities. Various strategies are employed to enhance English skills, including media consumption and interaction with native speakers. These findings underscore the importance of tailored support for learners at different proficiency levels, promoting increased engagement in English practice outside the classroom, and integrating cultural sensitivity training to enhance communication skills and intercultural competence.

تاريخ المرأة في الإسلام والنظريات النسوية منذ ستينيات القرن الماضي حتى العصر الحديث دراسة تاريخية.
Authors: الرديني ريم
Published: June 2024

تعد دراسة تاريخ المرأة من الدراسات الأكثر حيوية في الآونة الأخيرة، وعلى الرغم من أنه ماتزال كثير من النصوص السائدة تعطي مساحة صغيرة للنساء وتجاربهن الخاصة، فقد سادت علاقة وثيقة بين السياسات النسوية المعاصرة ونظرياتها والممارسات التاريخية النسائية، وتقدم الدراسة مجالات تاريخية مختلفة لكتابة تاريخ النساء في الإسلام منذ ستينيات القرن الماضي حتى العصر الحديث، وتركز على المناهج الجديدة للبحث والمفاهيم؛ حيث إن الدراسات العلمية تعد أفضل طريقة للتعامل مع هذه المهمة المحورية من خلال اختصاصها الأساسي في بناء المعرفة ونشرها. من هنا عرضت الدراسة لسؤالين مهمين، هما: ما نوع الكتابة الأكاديمي في كتابة تاريخ النساء في الإسلام وتقديمها في صور لأبحاث بعد التأثر بالحراك النسوي؟ هل أسهمت الموجات والنظريات النسوية في تفكيك طبقات من الوهم وإعادة كتابة تاريخ النساء في النصوص الإسلامية؟ إن المنهج المتبع في هذه الدراسة يعتمد على الدراسات الجندرية ذات الصلة بـ "تاريخ النساء" الذي نشأ، باعتباره ردّة فعل على التاريخ العام الذي كاد يكون مقصوراً على الرجال، لا يروي إلا الأحداث البارزة التي قام بها هؤلاء، فهمّشت نتيجة ذلك أدوار النساء ومساهماتهن البارزة أو الخفية. تركز الدراسة على المقاربة الجندرية التي تعني المقاربة بالنوع الاجتماعي في الثقافة الإسلامية تشمل الذكورة والأنوثة في الكتابة التاريخية لتاريخ المرأة في الإسلام، وتداخلات العرق والطبقة والهوية، وهو ما يمثل الدعامة الرئيسية لكتابة الحقيقة التاريخية، ومعرفة تاريخ النساء طبقة مهمشة بجميع أطيافها، وذلك يرجع إلى عدة أسباب تم استنتاجها من خلال هذه الدراسة، وهي معرفة تاريخ الأقليات المهمشة ووضعها وفهم الثقافات وربط دور السلطة بذلك، وفهم العلاقات بين الرجال والنساء وهي ما تصب في العلاقات الإنسانية. إن الاستثمار الفعال في فهم تاريخ المرأة دون وجود فكر إقصائي إلى أية فئة مهمشة في المجتمع وضم فئاته المختلفة والمشاركة الحقيقية لهن بمختلف الميادين، والاعتراف بأن التراث المهيمن على الوعي العام بعيد عن وجود مثل هذه المقاربة الجندرية؛ لذا يجب تفكيك هيمنته وسيطرة أفكاره وإعادة مشاركة النساء وتفكيك الخطابات الذكورية فيه من خلال إعادة صياغة الأحداث؛ إذ إن كتابة تاريخ المرأة في التاريخ الإسلامي ما هو إلا كتابة تاريخ جديد باستنطاق حقب صامتة.

أثر المستوى التعليمي والجنس على وعي وآراء مواطني دولة البحرين نحو القمامة المنزلية وإمكانية فصل بعض عناصرها.

لم تعد مشكلة القمامة المنزلية تخفى على أحد ، فقد أصبحت قضية يومية حيوية يواجهها الإنسان ويعاني منها ، وبخاصة المختصون في هذا المجال والمسؤولون عن إدارة القمامة ، حيث إنهم أكثر الناس التصاقا واهتماما بهذه المشكلة ، وأعمقهم وعيا ومعرفة بمردوداتها على الإنسان ومجتمعه إذا لم يتم التعامل معها بطريقة سليمة وصحية .

ولم تعـد هذه المشكلة تخص بلدا دون آخر ، وإنما تحولت الآن إلى مشكلة عالمية جلية في جميع دول العالم ، سواء كانت هذه الدول نامية أو صناعية متقدمة .

واتضحت خطورة المشكلة على نطاقها الواسع عندما نشرت الجرائد والمجلات المحلية والعالمية عن البارجة الأمريكية المعروفة باسم موبروا التي كانت تحمل على متنها 3100 طن من قمامة مدينة نيويورك ، وتبحر بها عرض البحر لتجد موقعا للتخلص منها . فقد بدأت البارجة رحلتها المجهولة في 22 مارس 1987م من إحدى موانئ نيويورك متجهة إلى مكان غير معروف للتخلص من حمولتها ، واستمرت في رحلتها نحو 6 أشهر حتى اضطرت في النهاية إلى الرجوع من حيث أتت . وهذه الحادثة تعتبر تحذيرا شديدا ، ليس للولايات الأمريكية فحسب ، وإنما لجميع دول العالم بدون استثناء .

أن الغاية من كتابة هذا البحث هي تحليل طبيعة وآثار ومحددات وطرق علاج العجز في الموازنة العامة لدولة الإمارات العربية المتحدة الذي ظهر مع بداية الثمانينات واستمر حتى الوقت الحاضر . وتنقسم الورقة إلى مقدمة وخمس أجزاء وخاتمة . فالجزء الأول هو وصف لحجم وتطور العجز خلال حقبة الثمانينات . أما الجزئين الثاني والثالث فهما عبارة عن تحليل لما يعرف بالحساب الموحد الذي يعتبر أشمل وأكثر تعبيرا عن الموازنة العامة لدولة الإمارات مقارنة بالموازنة الاتحادية التي لا تشتمل على إيرادات ومصروفات المؤسسات المحلية . وفي الجزء الرابع تقدم الورقة بعض المقترحات لعلاج هذا العجز في السنوات القادمة . بعد ذلك يركز الجزء الخامس من الورقة على أهم المحددات لهذا العجز في السنوات القادمة أي التسعينيات وما بعدها والتي تشتمل على أسعار النفط ، الأنفاق العسكري ، والإصلاحات الإدارية والمالية . وتتلخص استنتاجات الورقة في عدة نقاط أهمها أن الإيرادات النفطية التي تحققت في السبعينيات لن تتكرر في المستقبل القريب وهذا يعني أن علاج العجز لأبد أن يتركز على ترشيد النفقات العامة ، كما وأن تحقيق التكامل الاقتصادي بين دول المجلس سيزيد من فرص تحقيق التنمية المنشودة في المنطقة نظرا لما يحققه التكامل من تقوية للموقف التفاوضي وتحقيق شروط أفضل للتبادل التجاري بينها وبين بقية العالـم .
