Artificial Intelligence (AI) is revolutionizing education by enhancing classroom instruction, personalizing learning, and automating administrative tasks. As AI technologies integrate into pedagogy, they create immense opportunities but also raise significant ethical dilemmas. This paper explores the dual nature of AI in education: its promise to transform teaching-learning processes and the associated ethical concerns, including data privacy, algorithmic bias, and teacher de-skilling. The journal critically examines how AI tools like intelligent tutoring systems, predictive analytics, and generative AI models are reshaping classroom pedagogy. It further investigates policy frameworks, teacher preparedness, and the Indian context to suggest a balanced, ethical, and inclusive adoption of AI in education.

Critical illness is an exquisitely time-sensitive condition and follows a disease continuum, which always starts before admission to the intensive care unit (ICU), in the majority of cases even before hospital admission. Reflecting the common practice in many healthcare systems that critical care is mainly provided in the confined areas of an ICU, any delay in ICU admission of critically ill patients is associated with increased morbidity and mortality. However, if appropriate critical care interventions are provided before ICU admission, this association is not observed. Emergency critical care refers to critical care provided outside of the ICU. It encompasses the delivery of critical care interventions to and monitoring of patients at the place and time closest to the onset of critical illness as well as during transfer to the ICU. Thus, emergency critical care covers the most time-sensitive phase of critical illness and constitutes one missing link in the chain of survival of the critically ill patient. Emergency critical care is delivered whenever and wherever critical illness occurs such as in the pre-hospital setting, before and during inter-hospital transfers of critically ill patients, in the emergency department, in the operating theatres, and on hospital wards. By closing the management gap between onset of critical illness and ICU admission, emergency critical care improves patient safety and can avoid early deaths, reverse mild-to-moderate critical illness, avoid ICU admission, attenuate the severity of organ dysfunction, shorten ICU length of stay, and reduce short- and long-term mortality of critically ill patients. Future research is needed to identify effective models to implement emergency critical care systems in different healthcare systems.

To date, the effectiveness of acceptance and commitment therapy (ACT) for acute stroke patients has not been well recognized. The study aimed to discover the effectiveness of group-based ACT in treating depression for acute stroke patients. We conducted a randomized controlled trial with 140 acute stroke patients with depression. The ACT intervention comprised seven sessions, of 45-60min over 4 weeks. Data were collected pre- and post-intervention and at 3-month follow-up, assessing depression, health-related quality of life (HRQoL), psychological flexibility, cognitive fusion, sleep quality, and confidence. Overall, 99.3% of the included patients were assessed as having mild depression. The ACT intervention significantly reduced depression in acute stroke patients in comparison with the control group post-intervention and at 3 months (partial ). Additionally ACT significantly improved HRQoL-mental component summary, sleep quality, psychological flexibility, cognitive fusion, and confidence compared with control group. ACT is effective in treating acute stroke patients with depression, and the efficacy was maintained at 3-month follow-up.

This paper describes the experimental characterization of single-pass ion cyclotron resonance heating as applied to acceleration of ions for electric propulsion. A millimeter-wave interferometer system has shown to be a clear and simple method of quantifying ion acceleration due to ion cyclotron resonance heating. The experimental work was done on the VX-10 experiment of the variable specific impulse magnetoplasma rocket concept. The perpendicular velocity of the ions generated by ion cyclotron resonance heating was converted into axial velocity by the decreasing gradientoftheaxialmagnetic fieldattheexhaustofthepropulsionsystemfromconservationofthemagnetmoment.

InterferometerdensitymeasurementsweretakenatthreedifferentlocationsontheVX-10experimentupstreamand downstream of the ion acceleration zone. A clear measurement of a 25% density drop for helium and a 40% density drop for deuterium was measured downstream of the ion resonance zone characteristic of ion acceleration.

An attractive choice for low power neutralization, field effect electron emitters provide electron emission without heater power (as for thermionic emitters) or consumable gas requirements (as for hollow cathodes). One concern for contemporary field emitters, however, is their robustness while operating in ionospheric and electric propulsion environments. This presentation details experimental results of a phase-II STTR program run by ElectroDynamic Applications, Inc. in collaboration with the University of Michigan, to develop boron nitride as an electron emission substrate. A unique material for electron emission, with properties similar to diamond, boron nitride shows potential for significant improvement in the area of robustness while still providing low extraction voltages.

The usability of information is vital to successful websites, products, and services. Managers and developers often recognize the role of information or content in overall product usability, but miss opportunities to improve information usability as part of the product-development effort. This meeting is an annual forum on human factors of information design, in which we discuss issues selected by the group from the facilitators' list of topics, augmented by attendees' suggestions.

Effective participant recruitment is crucial to collecting reliable data during usability testing of high-tech products and services. Not only should test participants reflect the characteristics of the targeted users of the product or service, but they must also be likely to use it. Only then will their experiences and opinions yield reliable data for identifying meaningful improvements. This paper presents real-world challenges in recruiting participants for usability testing of new-technology products and services for which no firmly established customer base exists. It discusses techniques for meeting recruiting challenges, before and after test sessions begin, based on Tec-Ed Inc.'s usability-test case studies.

A veces la fama de un libro obstaculiza el conocimiento de las restantes producciones de un escritor. El xito de A riel eclips la importancia de los Motivos de Proteo, el libro ms personal e ntimo del pensador uruguayo. Sin embargo, en los ltimos aos, la crtica tradicional, dividida entre el elogio fcil y el rechazo arbitrario, ha dejado paso a estudios ms objetivos y juicios ms aquilatados, entre ellos los de Emir Rodrguez Monegal y Carlos Real de Aza que le han restituido no pocos de sus mritos.
