文化多元化视域下马克思主义大众化及其实践路径

文化多元化是当前我国马克思主义意识形态文化建设的基本文化生态。文化多元化在对人类文明进步产生巨大推动作用的同时,也对马克思主义主导意识形态文化建设带来了消极影响和认同危机。面对文化多元化负效应的影响,加快推进马克思主义大众化,就要坚持社会主义核心价值体系的引领,坚持主流文化的主导,正确对待传统文化的继承与弘扬,善于学习和借鉴人类文明的共同成果,同时坚持党领导下的理论创新等。     

问题导向促进在线学习者认知能力发展的研究

问题乃是通向理解之门.问题可以激发学习者的求知欲和探究欲,有利于推动教学的开展和促进学习者认知能力的发展.在线学习环境下为促进学习者认知能力的发展提供了丰富的认知工具和资源.但是,由于缺乏对教学问题导向作用的关注,在线课程在促进学习者认知能力发展方面存在着不理想之处,不能有效地引起认知上的深度理解.在文献研究和案例分析的基础上,综合分析了国内外问题导向在在线学习课程中的经验与不足,构建了问题导向促进学习者认知能力发展的在线学习框架和课程实例.在课程设计中提供了以问题为引导的情境体验和探究互动的机会,通过丰富的案例学习和认知支架,让学习者在问题解决过程中学会自主探究和深度思考,引导学习者从对知识的低水平认知层次逐渐向高水平认知层次发展.最后,为了验证问题导向在线课程对学习者认知发展的促进作用,采用实验调查等方法进行了实证研究.     

关于中等职业学校数学课堂教学策略的探索与实践

Genomic consequences of population decline in critically endangered pangolins and their demographic histories

Pangolins are among the most critically endangered animals due to heavy poaching and worldwide trafficking. However, their demographic histories and the genomic consequences of their recent population declines remain unknown. We generated high-quality de novo reference genomes for critically endangered Malayan (Manis javanica, MJ) and Chinese (M. pentadactyla, MP) pangolins and re-sequencing population genomic data from 74 MJs and 23 MPs. We recovered the population identities of illegally traded pangolins and previously unrecognized genetic populations that should be protected as evolutionarily distinct conservation units. Demographic reconstruction suggested environmental changes have resulted in a population size fluctuation of pangolins. Additionally, recent population size declines due to human activities have resulted in an increase in inbreeding and genetic load. Deleterious mutations were enriched in genes related to cancer/diseases and cholesterol homeostasis, which may have increased their susceptibility to diseases and decreased their survival potential to adapt to environmental changes and high-cholesterol diets. This comprehensive study provides not only high-quality pangolin reference genomes, but also valuable information concerning the driving factors of long-term population size fluctuations and the genomic impact of recent population size declines due to human activities, which is essential for pangolin conservation management and global action planning.     

C++Builder与MATLAB混合编程在企业智能化战略决策中的应用

企业战略决策是一个非结构化的过程,其形成机制难以清晰描述。本文讲述了如何利用MATLAB神经网络工具箱建立BP网络模型,结合BorlandC Builder具有的丰富可视化组件和SQLServer的数据库管理功能,调用MATLAB引擎进行混合编程,本文还讨论了编程设计过程,使系统能够辅助企业做出科学化的战略决策。     

析远程英语学习者之学习策略

本文通过问卷调查,分析研究了远程英语学习者的学习策略。结果表明:远程学习者常用的英语学习策略有:自我管理策略、记忆策略和语法策略等。许多成人学生在英语学习中不善于合理使用各种策略。作者认为在远程英语教学中要注意培养学生运用策略的能力,另外必要对面授辅导课给予足够的重视。     

论文化互动教育研究的价值取向、对象与方法

在联合国教科文组织大力推进文化互动教育走向国际化的进程中,愈来愈多的国家开始关注并积极助推文化互动教育的现代发展。纵观当前我国学界关于文化互动教育的研究成果,价值取向上,理论价值与实践价值并举;研究对象上,宏观、中观与微观相联结;研究方法上,时间—历史研究与空间—比较研究相互演进。然而,文化互动教育研究依然存在着理论研究的“薄弱化”、实践研究的“片段化”、综合研究的“浅表化”等问题。为此,今后的相关研究需要注重丰富更多视域的理论研究、畅显文化互动教育的具体实践研究、开展三观互联的综合性研究。     

Genomic diversity and post-admixture adaptation in the Uyghurs

Population admixture results in genome-wide combinations of genetic variants derived from different ancestral populations of distinct ancestry, thus providing a unique opportunity for understanding the genetic determinants of phenotypic variation in humans. Here, we used whole-genome sequencing of 92 individuals with high coverage (30–60×) to systematically investigate genomic diversity in the Uyghurs living in Xinjiang, China (XJU), an admixed population of both European-like and East-Asian-like ancestry. The XJU population shows greater genetic diversity, especially a higher proportion of rare variants, compared with their ancestral source populations, corresponding to greater phenotypic diversity of XJU. Admixture-induced functional variants in EDAR were associated with the diversity of facial morphology in XJU. Interestingly, the interaction of functional variants between SLC24A5 and OCA2 likely influences the diversity of skin pigmentation. Notably, selection has seemingly been relaxed or canceled in several genes with significantly biased ancestry, such as HERC2–OCA2. Moreover, signatures of post-admixture adaptation in XJU were identified, including genes related to metabolism (e.g. CYP2D6), digestion (e.g. COL11A1), olfactory perception (e.g. ANO2) and immunity (e.g. HLA). Our results demonstrated population admixture as a driving force, locally or globally, in shaping human genetic and phenotypic diversity as well as in adaptive evolution.     

广东省中超职业足球俱乐部后备人才培养研究* ——以广东省恒大、富力足球俱乐部为例

足球后备人才应走职业化培养道路已经得到广泛认同。但我国足球职业化的发展已经走过近20年,其成绩却一直不理想。出现这种现象的原因是多方面的,主要是由于青少年足球后备人才的足球职业化培养不够成功。近年来广东省中超职业足球俱乐部经过不懈的努力成绩不错,但其后备人才的职业化培养仍不容乐观。研究的重点在于了解广东省高水平中超足球俱乐部后备人才培养现状,找出职业化培养后备人才的不足,为提高后备人才的质量,促进足球运动发展提供参考的理论依据和对策。
