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.     

美､德个人信息宪法保护路径比较及启示——以个人信息的双重属性切入

个人信息的保护研究一般基于信息的人身性与财产性为选择保护的路径,却忽略了个人信息的人身依附属性.根据自由主义与社群主义对自我的解释得出个人信息具有个体性与公共性的双重属性.基于此双重属性导致美、德两国在个人信息保护模式上有所区别:美国将个人信息作为隐私权保护外延,显示其对信息个体性的追求;德国利用领域理论将个人信息作为人格尊严的保护客体,显示其对信息公共性的偏向.从法律文化视角比较,两国存在价值取向与隐私认可程度的差异,由此造成对个体性和公共性的不同偏向;两国又因司法谦抑主义与公共安全和个人信息保护的竞争,导致保护限缩的共同趋向.两种保护路径反映不同的法律文化的同时,也体现出两国都重视在立法基础上的宪法审查运用,以此平衡个人信息的个体性与公共性.故我国个人信息保护亦需以“审查”作为个人信息保护的有效方式,并以个体性与公共性的动态平衡作为判断标准.具体审查可以从程序上的公正平衡与实体上的合理平衡两方面进行判断,以此为个人信息提供有效保护.此外,打破个体性与公共性平衡状态的唯一变量只能基于公共利益的考量.     

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.     

粤港澳大湾区西部核心产业创新空间提升规划思考 ——以顺德为例

在粤港澳大湾区一体化发展背景下,顺德以土地换产值的传统增长模式难以为继,制造业面临巨大的下行压力,根本原因是城市创新空间系统性、产学研协同创新转化、优质服务的创新空间不能匹配顺德日益增长的发展需求.本文结合产业创新空间相关基础研究,从内外部创新空间格局视角,重点梳理顺德产业创新空间方面的规划探索.从区域创新合作、多元创新协同、提升空间供给等方面总结既有经验并提出新的思考.     

认罪认罚被告人上诉问题研究——以检察业务为视角

适用认罪认罚制度得到从宽处罚的被告人仍有部分提出上诉,其中以量刑过重为由的投机型上诉占大多数,尽管如此,认罪认罚被告人的上诉权仍应全面保留,对于因不合理上诉导致认罪认罚从宽制度效率价值无法充分发挥的问题,检察机关应当提升检察业务水平,加强沟通联系,强化释法说理工作,以减少被告人的不合理上诉,推进认罪认罚从宽制度的实施。
