Healthcare delivery systems have determinative implications for the availability, cost, effectiveness, and patient experiences of society’s medical care system. More recent developments, including value-based care and integrated models, are nevertheless characterized by such disparities, most especially for the rural and economically less privileged citizens, thus underlining the role of drastic change. They suggest that the conventional model, such as fee-for-service and managed care, is not effective enough to transform systematic problems, while new models like patient-centered medical homes and Accountable Care Organizations could develop more effective frameworks. However, these innovations have drawbacks like poor scalability, non-uniform take-updates, and erratic policy intervention, which makes them insufficient to fill the gaps in accessibility and efficiency in one go. The ten barriers discussed here are geographical location, shortage of these specialists, and cost to patients, which imply the need to maintain equity in dispensing healthcare services. Additionally, established indicators of quality demonstrate that there is considerable instability in the results associated with patient satisfaction, clinical results, and organizational effectiveness; this underscores the need for the further application of ICTs such as telehealth, artificial intelligence and analytics to underpin successful processes and support decision-making. This work examines the existing models of the specified problem in detail, categorizes the problem into critical areas of improvement, and synthesizes the problem using literature reviews, quantitative assessment, and presentation of the problem graphically. It is supposed to offer a set of recommendations on how to achieve this goal and incentivizing innovative care networks, building out digital health, and advancing policy changes that support population-health approaches to delivering care. Filling these gaps is crucial for getting a healthcare system that is fair, cheap and capable of producing quality health for all population types as they need.

Healthcare accessibility is one of the main determinants of health in the population and the world. The three A’s, access, cost, and availability of health facilities, play a significant role in how quality health care is being delivered and, in the effort, to prevent diseases and improve the health standards of the communities. Analyzing healthcare access models, this paper discusses best practices as well as problems that have been observed in different world regions. Major factors are assessed, including UHC, selective health policies, PPL, and the implementation of technologies for describing and increasing access to health care services. The research also focuses on a particular aspect of healthcare availability: the number of accessible healthcare facilities available to people and the extent to which they can address the population’s health needs in terms of existing disparities, economic burden, and response to emerging public health issues. This paper analyzes global case studies that reveal emerging challenges and suggest solutions to strengthen healthcare access for diverse populations.

Labor informality is a phenomenon that impacts the economic and social development of various regions, including the department of Puno, by limiting access to labor rights and perpetuating poverty and inequality. This study aims to determine the socioeconomic factors that influence labor informality in the department of Puno. To achieve this objective, a methodology with a quantitative approach of explanatory scope and a non-experimental cross-sectional design was used, analyzing data from the National Household Survey (ENAHO) of the National Institute of Statistics and Informatics (INEI), whose sample was made up by 1,771 individuals of working age from the department of Puno. The results revealed that factors such as sex (p = 0.0470), educational level (p = 0.0000), age (p = 0.0000), area of ​​residence (p = 0.0040), financial inclusion (p = 0.0000), the type of employer occupation (p = 0.0290), the type of contract (p = 0.0000), the monthly income (p = 0.0000), the size of the company (p = 0.0010) and the type of commercial economic activity (p = 0.0000) were determining factors of labor informality. In conclusion, it is established that socioeconomic factors significantly influenced labor informality in the department of Puno, which implies that public policies should focus on improving access to education and financial services to promote the formalization of employment and, therefore, improve the living conditions of the working population.
فرهنگ و تنوع فرهنگی در فلسفه هردر
Authors: فطرت بریالی
Published: December 2024

فرهنگ و تنوع فرهنگی مهمترین درون‌مایه کار فکری هردر و موضوع محوری فلسفه این متفکر است. هردر معنای وسیعی برای فرهنگ در نظر دارد و فرهنگ را «محصول و آفریده ممتاز یک قوم یا ملت در طول تاریخ برای رفع نیازهایش» می‌داند. در نگاشتن این مقاله از روش کتابخانه با رویکرد مروری و مطالعه آثار معتبر مرتبط با مسئله تحقیق، ‌استفاده شده و از خلال این تحقیق دریافتیم که فرهنگ آفریده روحی و معنوی انسان بوده و تنوع فرهنگی ریشه در مشیت الهی دارد. اهمیت این تحقیق، یکی این است که ما را متوجه می‌سازد که فرهنگ، در کنار واژه‌هایی چون انسانیت و کمال، بر اموری مطلوب و والا دلالت داشته؛ و آن‌چه بیشتر سرنوشت و هویت یک ملت را می‌سازد فرهنگ است نه سیاست.

Published: December 2024

وضیعت خاص کودکان کار شاقه سبب شده تا آنان هم در جامعه و هم در محیط خانوادگی، در معرض انواع سوءاستفاده و آسیب‌ها قرار گیرند و به انبوهی از حمایت‌ها نیازمند باشند. تنها یکی از جلوه‌های حمایت از این کودکان ارتقای سلامت اجتماعی آنان است. سلامت اجتماعی عبارت است از ارزیابی و شناخت فرد از چگونگی عملکردش در اجتماع می‌‌باشد. ‌‍‍هدف از این تحقیق دریافت میزان سلامت اجتماعی کودکان کار شاقه بوده که 97 پرسش‌نامه از کودکان کار شاقه ناحیه هفتم شهر کابل جمع‌آوری شد. جهت بررسی سلامت اجتماعی از پرسش‌نامه سلامت اجتماعی کیز (۲۰۰۴) استفاده شد. سلامت اجتماعی کودکان کار شاقه با میانگین ۸۳.۱۶ در حد مطلوب قرار نداشته است. نتایج این مطالعه نشان داد سلامت اجتماعی کودکان کار شاقه از وضعیت مطلوبی برخوردار نیست. بنابراین جهت شناسایی و ارتقای سلامت اجتماعی و حذف عوامل مؤثر بر پدیده‌ی خیابانی کودکان، تلاش مشترک کلیه سطوح جامعه را می‌طلبد.
تحلیل نظریه نخبه‌گرایی از نظر جامعه‌شناسی سیاسی
Authors: حبیبی محمدخالد
Published: December 2024

در جامعه‌شناسی سیاسی نظریه نخبه‌گرایی از اهمیت به‌سزایی برخوردار بوده و متکی براین اصل است که ماهیت هر جامعه توسط ماهیت نخبگان آن تعیین می شود؛ بنابراین هدف ما در این مقاله شناخت، توضیح و تحلیل این نظریه از دیدگاه جامعه‌شناسی سیاسی می‌باشد. اهمیت تحقیق در این مسأله از آنجا ناشی می‌شود که نظریه نخبه‌گان می‌تواند ما را در شناخت ماهیت ساختار سیاسی جوامع کمک کند. برای تحریر این مقاله روش تحقیق کتابخانه‌ای‌ و تحلیل کیفی استفاده شده است. یافته‌های تحقیق نشان می‌دهد که نخبه‌گرایی نه تنها در دوره های گذشته؛ بلکه در دروان معاصر نیز به‌عنوان یک نظریه عمده در جامعه‌شناسی سیاسی مطرح بوده و علاوه بر تفکر سیاسی غرب از منابع اسلامی نیز می‌تواند نظریه نخبه‌گرایی را استخراج نمود و در اندیشه‌های متفکرین اسلامی نیز مباحث ارزش‌مند در باب نظریه نخبه‌گرایی وجود دارد.

Published: December 2024

رابطه معرفت و سعادت در فلسفه ابن‌سینا یک بررسی پدیدارشناختی است که این رابطه را در انحا و وجوه مختلف پی می‌گیرد. مسئله‌ی این مطالعه، نقش معرفت و پرورش قوه عاقله در تحصیل سعادت است. این مطالعه تحلیلی و توصیفی است که به روش مروری با استفاده از منابع معتبر انجام شده است. این تحقیق به دنبال دست‌یابی به اهداف مختلف از جمله دریافت نحوه‌های رابطه بین معرفت و سعادت در فلسفه ‌ابن‌سینا می‌باشد. یکی از یافته‌های این تحقیق، این است که فلسفۀ ابن‌سینا، فلسفۀ کمال‌گرا و سعادت‌گراست و نگاه سعادت‌محور به معرفت دارد که به خودسازی و خودشناسی انسان نیز منتهی‌ می‌شود. دراین فلسفه بحث سعادت از لذت و بهجت آغاز می‌شود و بعداً به مفاهیم کمال، خیر و انبساط روحی انسان می‌رسد. معرفت نه‌تنها ما را به تجربه سعادت در این جهان یاری می‌کند؛ بلکه داروی سعادت در جهان دیگر نیز هست. اهمیت این تحقیق، این است که ما را متوجه می‌سازد که پرورش قوه عاقله و کسب دانش، راه ورود به سعادت واقعی و نامتزلزل است.
تأملی بر نظریهٔ اخلاق در منظومه فلسفی ابن‌سینا
Authors: حبیبی محمد خالد
Published: December 2024

ابن‌سینا از مؤسسین و پیشوایان برجستهٔ مکتب مشائی اسلامی در تمدن و فرهنگ اسلامی است. هرچند در مباحث علم اخلاق ابن‌سینا تحت تأثیر اندیشه‌های اخلاقی ارسطو و فارابی قرار دارد؛ چنان‌که از اندیشه‌های این فیلسوف بر می‌آید او باب مستقلی را متناسب با پیش‌فرض‌های انسان‌شناختی فلسفهٔ خود برای تحقیق و تبیین ویژگی‌ها، فضایل و مزایایی اخلاقی گشوده است که تحلیل و بررسی این مطالب هدف اصلی این تحقیق را تشکیل می‌دهد. روش تحقیق مقاله حاضر از نوع روش تحقیق مروری است و تلاش صورت می‌گیرد تا موضوعات به‌صورت عمیق و همه‌جانبه مطالعه و تحلیل گردد. در نتیجه می‌توان گفت که برای ابن‌سینا اخلاق به‌صورت عموم در سه طبقه خلاصه می‌شود. اخلاق عامه، اخلاق خواص و اخلاق اخص. ابن‌سینا فضیلت را فصل ممیز انسان از دیگر جان‌داران دانسته و در نظر او تقوا برای سلوک روحانی و اشراقی آدمی مؤثریت حیاتی و تعیین‌کننده دارد.

Published: December 2024

Este artículo muestra la disertación teórica utilizada para fundamentar una investigación en proceso, cuyo objetivo es explicar de qué manera una estrategia didáctica orientada en la pedagogía del posmétodo contribuye a mejorar la competencia comunicativa, en inglés; el estudio implica una amplia posibilidad para potenciar la competencia comunicativa en inglés, ya que al ser una estrategia orientada en la pedagogía del posmétodo, permite tener en cuenta las necesidades e intereses de los estudiantes, como las características locales del contexto, donde la escuela no es un ambiente aislado de su realidad, sino un espacio para reconocerse y trabajar en favor de su desarrollo personal y social, vinculando, a su vez, su vida real con el proceso de aprendizaje del inglés, y posibilitando así la generación de discurso oral y escrito en dicho idioma, y por tanto, la práctica y potenciación de estas habilidades. Este estudio se realizó con 23 estudiantes de grado octavo de una sede rural, en el municipio de ciénega Boyacá, Colombia, a través de un enfoque mixto, con un diseño explicativo secuencial (DEXPLIS); para recoger la información se utilizaron textos orales y escritos producidos por los estudiantes y una entrevista semi estructurada. Debido a que es un estudio en proceso aún no se tienen resultados concretos, pero se ha observado gran motivación por parte de los estudiantes al incluir las vivencias de su cotidianidad como contenidos y recursos de enseñanza.
Cultivating Consciousness: A Meta-Abilities Model for 21st Century Academic Leadership Development
Authors: Gomez Medina Carlos Javier , González Martínez María Cristina
Published: December 2024

This investigation integrates consciousness expansion into UK academic leadership training to address complex educational environments. Utilizing an integrative review and Grounded Theory elements, it presents the Conceptual Model of Consciousness Development for Academic Leaders (CMDAL) encompassing seven components: Self-awareness, Self-regulation, Cognitive Development, Interpersonal domain, ethical development, spiritual development, and Change capacity (adaptability). Significant and complex challenges that cannot be resolved with traditional ways have evidenced the gap between them and current competencies-based leadership training; Models that use a holistic approach are more appropriate for developing academic leaders; Consciousness expansion is the pillar of these holistic models. The CMDAL proposed model, focusing on seven dimensions highlights the importance of complementing current holistic leadership development with elements of consciousness expansion to develop higher-order abilities or Meta-abilities that can enhance leadership effectiveness as they foster psychological maturity.
Future research should address the empirical validation of the model. Limitations include more analysis for context-specific adaptations and longitudinal research/testing to establish efficacy.

Authors: Coronel Puello María Concepción
Published: December 2024

Este artículo es producto de la investigación doctoral titulada ‘El rol de la mujer en el Periodismo Deportivo en Colombia desde la mirada de las y los profesionales del canal RCN Radio de la ciudad de Cartagena, Colombia’. Se realizaron entrevistas semiestructuradas a siete mujeres periodistas para determinar cuáles han sido las experiencias y los desafíos que han representado para ellas incursionar en el periodismo deportivo, así como el exponer aquellas situaciones relacionadas con el desarrollo de su profesión en las cuales han sufrido algún tipo de discriminación en función de su género.

Measuring wind turbine noise poses significant challenges due to dynamic wind conditions, low-frequency components, and the presence of residual noise sources, including insect vocalizations. Long-term measurements are crucial for capturing the complex interplay of variables influencing sound propagation and for informing effective mitigation strategies. Our study leverages extensive insect sound recordings to develop classification methods for automatic exclusion of insect noise during wind turbine noise measurements with feature extraction and unsupervised learning. We highlight the challenges posed by dynamic environmental conditions and advocate for innovative approaches to filter out residual noise sources and enhance the accuracy of wind turbine noise assessment. Insect calls significantly affect sound pressure levels (SPL) at lower wind speeds. Moving forward, interdisciplinary research efforts and technological advancements are essential to address the complexity of wind farm noise and its impacts comprehensively, ensuring sustainable development and minimizing adverse effects on human health and biodiversity.

The measurement of angular velocity in rotating systems holds significant importance, especially in industrial applications. Various methods, both contact and non-contact, have been developed for determining angular velocity. This paper presents a notable contribution in the form of the design and implementation of a stroboscopic system characterized by the capability to fine adjustment the frequency of stroboscopic pulses using a multi-turn potentiometer, along with minimal energy consumption and low implementation cost, owing to the utilization of widely available components. To evaluate the performance of the stroboscope, a rotating system based on a DC motor was designed and implemented, whereas the rotation speed is controlled by a PWM signal. Additionally, to verify the accuracy of the measurements obtained with the implemented stroboscope, an angular velocity measurement system based on a photointerrupter was also developed.
