Abstract

This study examines the state of urban entrepreneurship in El Salvador, focusing on its transition to digital environments. Employing a qualitative, phenomenological approach, the research analyzes the lived experiences of 12 entrepreneurs from the eastern region of the country, selected through purposive sampling. Data were collected via semi-structured interviews and participant observation, leading to the identification of key thematic categories: offline–online integration, market reach, technological adaptation, and cultural influence. The findings indicate that social media platforms play a crucial role in expanding market access, reducing operational costs, and re-signifying cultural symbols within commercial practices. Despite these benefits, the persistent digital divide and technological barriers constrain the full transformative potential of digital entrepreneurship. The study concludes that successful integration between physical and virtual commercial domains relies not only on access to digital infrastructure but also on entrepreneurs' capacity to navigate evolving sociocultural dynamics. This research advances the field of commercial cyber-anthropology and provides practical insights for strengthening the local digital economy in developing contexts.

Abstract

This study aims to enhance the dynamic response of a flexible link robot manipulator (FLRM) to achieve faster positioning, improved trajectory tracking, and effective suppression of link deflection. A dynamic model of the FLRM was developed, and a hybrid control strategy integrating a proportional–integral–derivative (PID) controller with a linear quadratic regulator (LQR) was designed and implemented within the closed-loop system architecture. The complete system was modeled and simulated using MATLAB/Simulink. Initial simulations assessed the performance of the PID and LQR controllers independently. The PID controller yielded a rise time of 0.2617 s, peak time of 0.9434 s, settling time of 3.2394 s, and overshoot of 11.9676%. In contrast, the LQR controller demonstrated superior dynamic characteristics, with a rise time of 0.2505 s, peak time of 0.3489 s, settling time of 0.4769 s, and minimal overshoot of 0.0048%. To further enhance system performance and reduce trajectory tracking error, a hybrid PID–LQR controller was developed, incorporating refined PID parameters. Simulation results showed that the hybrid controller achieved a rise time of 0.1444 s, peak time of 0.2706 s, settling time of 0.2637 s, and overshoot of 0.5119%. These outcomes demonstrate that the PID–LQR hybrid controller significantly outperforms the individual PID and LQR approaches by achieving near-zero overshoot, faster response, and reduced stabilization time.

Abstract

Neurodegenerative disorders represent a significant and escalating global healthcare challenge, characterized by the progressive degeneration of neurons and a consequent decline in cognitive and motor functions. Among older adults, Alzheimer’s disease (AD) is the most prevalent neurodegenerative condition, marked by hallmark neuropathological features such as intracellular hyperphosphorylated tau (p-tau) forming neurofibrillary tangles, synaptic dysfunction, neuronal loss, and extracellular amyloid beta (Aβ) plaque accumulation. Aluminium (Al), a known neurotoxic metal, can cross the blood-brain barrier and accumulate in brain tissue, inducing changes associated with neurodegeneration. Additionally, D-galactose (D-gal) is frequently used in animal models to accelerate aging by inducing oxidative stress and inflammation, thus serving as a valuable tool in anti-aging and neurodegenerative research. This study investigates the therapeutic potential of Ziziphus mauritiana extract (ZME), a traditional medicinal plant with recognized nutritional and pharmacological value, in mitigating cognitive dysfunction induced by Aluminium Chloride (AlCl₃) and D-galactose in Wistar rats. Thirty-five healthy adult male rats (80–120 g) were administered D-gal (60 mg/kg, intraperitoneally) and AlCl₃ (200 mg/kg, orally) to induce neurodegeneration. Two experimental groups received ZME at doses of 100 mg/kg and 50 mg/kg, respectively, while the positive control group was treated with donepezil (1 mg/kg). Cognitive function was assessed using the Novel Object Recognition (NOR) test, oxidative stress was evaluated via Superoxide Dismutase (SOD) activity, and histological examination of the prefrontal cortex was conducted to assess neuronal integrity. Results revealed that exposure to AlCl₃ and D-gal significantly impaired cognitive performance, reduced SOD levels (p < 0.05), and induced morphological alterations in the prefrontal cortex. Treatment with ZME significantly improved cognitive performance, elevated SOD activity, and restored cortical architecture, indicating neuroprotective effects. These findings support the potential of Ziziphus mauritiana as a therapeutic agent for mitigating AD-related cognitive impairments through its antioxidative and neuroprotective mechanisms.

Abstract

The rapid urbanization of the 21st century has significantly reshaped global food production and consumption patterns, with profound implications for food security and sustainability, particularly in developing countries. With over 56% of the global population now residing in urban areas (World Bank), cities have become increasingly dependent on rural agricultural systems and food imports. This reliance leads to elevated transportation costs, higher carbon emissions, and heightened vulnerability to global supply disruptions. In response, small-scale food production within urban and peri-urban environments presents a promising solution. Models such as community gardens, rooftop farms, and family farming initiatives not only decrease dependence on external food sources but also support environmental sustainability, bolster local economies, and improve urban residents’ quality of life. Despite these benefits, the implementation of urban agriculture faces considerable challenges, including limited access to cultivable land, inadequate infrastructure, and regulatory constraints. Public perception and community engagement are critical factors influencing the adoption and long-term viability of these practices. This article explores the role and impact of urban agriculture in addressing food insecurity, with a specific focus on San Miguel, El Salvador. It highlights the potential of agro-architectural innovations and community-based approaches in enhancing urban resilience and sustainability. The study concludes with strategic recommendations to foster broader adoption of urban agricultural practices through supportive policies, infrastructure development, and awareness campaigns.

Abstract

Roads today are often equipped with speed breakers, which, although intended to control vehicle speed and reduce accidents, frequently cause inconvenience and potential hazards, especially when drivers encounter them unexpectedly. Speed breakers were introduced to curb the risks of collisions due to overspeeding; however, their physical implementation can disrupt vehicle movement and comfort. This study proposes a smart speed variation system for electric vehicles using a Fuzzy Logic Controller, aimed at eliminating the need for physical speed bumps while ensuring road safety. In the proposed system, a transmitter is placed at the entry point of a road segment with a designated speed limit. This transmitter sends a specific frequency corresponding to the speed limit, which is received by oncoming vehicles equipped with a compatible receiver. Upon receiving the signal, the vehicle automatically adjusts its speed to comply with the set limit. When the vehicle exits the restricted zone, it receives another signal permitting it to resume normal speed. This intelligent speed control system enhances driving comfort, ensures safety by maintaining regulated speeds, and contributes to energy efficiency in electric vehicles. The system was developed and simulated using MATLAB/Simulink with fuzzy logic to handle the dynamic control of vehicle speed based on environmental inputs. The simulation results confirm that speed variation can be effectively achieved through vehicle-to-infrastructure communication, demonstrating a viable alternative to traditional speed control mechanisms.

Abstract

This systematic literature review investigates the current state of English teacher education in Latin American universities, highlighting key challenges and opportunities in the preparation of competent educators. Drawing on peer-reviewed literature sourced from academic databases such as Google Scholar and Semantic Scholar, the study synthesizes findings from recent publications in both English and Spanish. The analysis reveals persistent curriculum deficiencies, notably the disproportionate emphasis on theoretical knowledge at the expense of practical training, limited integration of information and communication technologies (ICT), and inadequate incorporation of cultural identity. Additionally, neoliberal educational policies are found to hinder pedagogical innovation by prioritizing accreditation metrics over meaningful instructional reform. Despite these challenges, emerging approaches such as interactive didactics demonstrate promise, with evidence indicating a 4% improvement in teaching efficiency. The review advocates for curriculum models that balance linguistic competence, hands-on teaching experience, and cultural responsiveness, while also addressing digital inequities and systemic policy barriers. Future research should assess the long-term efficacy of innovative pedagogical strategies and develop context-sensitive models to strengthen English teacher education across diverse Latin American contexts.

Abstract

This study investigates the use of mobile device applications for English language learning among university students enrolled in virtual EFL (English as a Foreign Language) courses in El Salvador. Adopting a descriptive, quantitative, and relational research design, data were collected from 199 students across all academic levels within an English language bachelor’s program. Findings reveal that nearly half of the students report an intermediate level of engagement with mobile apps for English learning. However, a notable portion of students do not utilize entertainment-based language learning apps, indicating selective use based on perceived educational value. Statistical analysis shows a significant variation in app usage by academic level, with advanced students demonstrating higher engagement. No significant difference was found based on gender. These results reflect increasing digital competence among university students and emphasize the importance of providing targeted support and structured integration of mobile learning tools within virtual EFL curricula to enhance language acquisition outcomes.

Abstract

The central narrative guiding ethical concerns in Nigeria's media landscape is the alarming rise of fake news, hate speech, questionable source credibility, quackery, and weak internal censorship—practices that contribute significantly to ethical lapses across online journalism platforms. In an era increasingly dominated by sensationalism and disinformation, there is diminishing emphasis on ethically sound and balanced reporting, which traditionally underpins objective journalism. This study investigates the ethical challenges associated with online reporting practices in Nigeria, with a specific focus on the proliferation of fake news across digital media platforms. Anchored in the Social Responsibility Theory, the research employs focus group discussions and key informant interviews for data collection. A systematic sampling technique was used to select 5,944 registered journalists, media scholars, and members of the Nigerian Union of Journalists’ ethics committee from all six geo-political zones. Data were analyzed through detailed thematic probes and discussions. Key findings reveal a significant lack of comprehensive understanding of media laws among practitioners, many of whom are unaware of the legal implications tied to their professional responsibilities. The study highlights the critical need for clearly defined editorial policies to enhance source credibility and mitigate the spread of fake news and hate speech. Furthermore, ethical non-compliance is largely driven by the presence of untrained individuals posing as media influencers across various internet-based platforms. The study recommends deliberate efforts to improve awareness and enforcement of media laws, the establishment of a strong regulatory framework by both government and the Nigerian Union of Journalists, and ongoing training and retraining programs for digital media practitioners to uphold ethical journalism standards.
