The Historic Achievements of the Communist Party of China in Respecting and Protecting Human Rights in the New Era

In the new era,the Communist Party of China(CPC)has made historic achievements in respecting and protecting human rights.Building upon the principle of the“two integrations”(integrating the basic tenets of Marxism with China’s specific realities and fine traditional culture),it has nurtured new theories on respecting and protecting human rights in the new era,which can address the fundamental questions of whom and what the human rights protection efforts in the new era are for.Guided by the principle of“taking our own path,”it has charted a distinct course for the development of human rights,diverging from the Western approach.The CPC has maintained the unity between Party leadership and the respect for and protection of human rights,promoting progress in human rights through the pursuit of“high-quality development,”and ensuring various fundamental rights of the people through the rule of law.Building upon the past experience,the CPC has established the“source”of the institutional framework for respecting and protecting human rights in the new era,crafted the“body”of this institutional framework,and introduced its practical“application.”In promoting the comprehensive advancement of human rights protection,the CPC has facilitated the connotative development of human rights protection in China,empowering China in international human rights discourse,and contributing Chinese strength and wisdom to global human rights governance.

A Study on the Impact of Voice-to-Text Technology on Academic Achievement of the Hearing-Impaired

Hearing loss is a significant barrier to academic achievement,with hearing-impaired(HI)individuals often facing challenges in speech recognition,language development,and social interactions.Lip-reading,a crucial skill for HI individuals,is essential for effective communication and learning.However,the COVID-19 pandemic has exacerbated the challenges faced by HI individuals,with the face masks hindering lip-reading.This literature review explores the relationship between hearing loss and academic achievement,highlighting the importance of lip-reading and the potential of artificial intelligence(AI)techniques in mitigating these challenges.The introduction of Voice-to-Text(VtT)technology,which provides real-time text captions,can significantly improve speech recognition and academic performance for HI students.AI models,such as Hidden Markov models and Transformer models,can enhance the accuracy and robustness of VtT technology in diverse educational settings.Furthermore,VtT technology can facilitate better teacher-student interactions,provide transcripts of lectures and classroom discussions,and bridge the gap in standardized testing performance between HI and hearing students.While challenges and limitations exist,the successful implementation of VtT technology can promote inclusive education and enhance academic achievement.Future research directions include popularizing VtT technology,addressing technological barriers,and customizing VtT systems to cater to individual needs.

Achievability of Chong-Motani-Garg relay channel capacity bounds using forward decoding

To reduce decoding delay of a communication scheme which is backward-decoding-based and achievable Chong Motani-Garg capacity bounds, a novel forward-sliding-window decoding-based communication scheme is proposed. In this scheme, if w = （w1, w2） is the message to be sent in block b, the relay will decode message w1 and generate a new message z at the end of block b, and the receiver will decode message w1 at the end of block b ＋ 1 and decode message z and w2 at the end of block b ＋ 2. Analysis results show that this new communication scheme can achieve the same Chong-Motani-Garg bounds and the decoding delay is only two blocks which is much shorter than that of backward decoding. Therefore, Chong-Motani-Garg bounds can be achieved by a forward decoding-based communication scheme with short decoding delay.
