河北省威县传统土布纺织的历史发展与当代传承

河北省威县土布纺织历史渊源深厚，2014年被列入“国家级非物质文化遗产代表性项目”保护名录。威县土布纺织以图案纹饰形态为载体，以独特的挑经通纬工艺，表现了土布纺织的吉祥寓意之美和希冀驱邪挡灾的民俗观念。近几年威县通过建立技艺传习所、复原原生态技艺以及研习交流探寻了非物质文化遗产的保护传承之路，并取得了一些成效。通过文旅融合、创新产品设计、打造地域文化品牌、搭建共融平台等途径，有助于构建威县土布纺织传承发展的新生态。     

城镇化、工业化对农业全要素生产率增长的影响研究——来自重庆37个县(区)面板数据的证据

文章基于2000—2016年重庆37个县（区）面板数据，使用序列DEA方法测算了重庆农业全要素生产率变动，在此基础上探讨了重庆农业全要素生产率增长的时间演变，并从理论和实证层面系统考察了城镇化和工业化对农业全要素生产率增长的影响。结果表明：首先，2000—2016年间重庆市农业全要素生产率呈上升趋势，2007年后重庆市农业全要素生产率增长更为明显，并且重庆市各地区呈现出明显的空间不平衡性。其次，动态面板模型的实证结果表明城镇化对农业全要素生产率增长具有显著正向影响，工业化对农业全要素生产率增长也具有显著正向影响。最后，研究还发现基础设施、教育水平以及金融发展程度对农业全要素生产率增长均具有显著正向影响，而产业结构对农业全要素生产率增长具有显著负向影响。     

基于OBE教育理念的土木工程专业英语教学改革实践

为提高土木工程专业学生的英语应用能力和《土木工程专业英语》课程的教学效果，本次教改实践以OBE（成果导向教育）教育理念为教改指导思想，以土木工程专业英语教学为教改对象，设计了土木工程专业英语教学的教学内容、教学组织和教学评价等教学环节，在河北工程大学土木工程专业学生中进行了教改实践。教改实践结果表明，基于OBE的土木工程专业英语教学模式在提升土木工程专业学生英语应用能力方面具有很好的效果。本次教改实践的成果值得本校其他工科专业和其他兄弟院校借鉴。     

Deterministic construction of compressed sensing matrices based on semilattices

A central problem in compressed sensing is the construction of sensing matrices. In this paper, we show how to construct sensing matrices by using semilattices, and give many examples of sensing matrices constructed from specific semilattices. Moreover, we show that the new construction for some examples with small parameters gives better sensing matrices compared with previously known constructions.     

Species richness,phylogenetic and functional structure of bird communities in Chinese university campuses are associated with divergent variables

University campus is an important component of urban landscapes for biodiversity conservation. However, to our knowledge no study has quantitatively assessed the diversity and structure of bird communities in Chinese university campuses, especially from phylogenetic and functional perspectives. Here, for the first time we linked species richness, phylogenetic structure and body mass structure of campus bird communities with contemporary climate, glacial-interglacial climate change, altitudinal range, population density around campus, area and age of campus to test their associations. We found 393 bird species in 38 university campuses (29% of all Chinese bird species, two species are endangered, four species are vulnerable, and 33 species are near threatened). The variables significantly correlated with campus bird species richness, phylogenetic structure and body mass structure were altitudinal range and mean annual precipitation, glacial-interglacial anomaly in temperature, and altitudinal range, respectively. In particular, there were more species in steeper and wetter campuses, more young species clustered in campuses with stable glacial-interglacial climate, and more species with smaller body size in steeper campuses. Our study highlights the importance of considering both phylogenetic and functional information for biodiversity conservation in urban ecosystems.     

Chinese youth performing identities and navigating belonging online

This paper examines the experiences of belonging of young Chinese internet users through an analysis of their online identity practices. Drawing on a qualitative research project about online citizenship practices of 31 young Chinese citizens from mainland China, I explore their experiences of belonging on two online platforms (Weibo and WeChat) and the identities formed and sustained through these experiences. The results show that young people experience different senses of belonging in different social media spaces. Their strategies in navigating these experiences are informed by (a) their perceptions of online spaces as private or public, and (b) using online identity performance as a supplement to or escape from identities in physical life. I argue that young Chinese internet users experience different senses of belonging by flexibly appropriating the affordances of social media platforms for communication and networking; these senses of belonging play a key role in forming and sustaining their identities, and are crucial for their wellbeing.

杜甫《登高》诗中的乐观主义精神探微

杜甫写于唐大历二年(767年)秋天的《登高》诗,虽是其晚年凄凉与孤独生活状态的真实写照,但诗中却充满着令人激动的气势.这种气势不仅源于杜甫对登高文学传统的继承,亦是其晚年面对迁逝之感时昂扬生命意识的展现.除了感时伤事,诗中还深刻蕴含着杜甫晚年的壮阔情怀以及乐观主义精神,这种精神与夔州相对安定的生活有着密切关联,更是其儒家思想的重要体现.
