马克思主义关于人的发展与社会发展问题

人的发展和社会发具有内在关联性,但马克思主义所关注的人的发展是人的本质力量的发展,即人的劳动能力的发展、人的社会关系的发展。人的发展是一个社会历史过程,又是一个理想目标,社会发展是社会进步的过程,是人类生产力不断提高、人们的社会关系不断进化的过程。实践的观点是理解二者的关键,二者既具有同一性,又具有矛盾性,是一个永恒的矛盾运动的过程。

农村大学生的角色认同与学校适应研究

随着社会变迁的加剧,农村大学生由于早期社会化环境的影响,进入高校以后,出现学校适应问题,表现为角色认同延缓、封闭和角色混淆甚至导致角色失败。而认同理论视角下的角色认同有助于农村大学生接纳自我和环境,从被动接受转变为主动参与,较快适应高校生活。为农村大学生的顺利社会化和构建和谐校园提供理论指导和实践支持。     

《大学图书馆学报》期刊引用认同实证研究

引用认同是Howard D.White在2001年提出的,它同时对引用和施引期刊进行研究,获得了有关引用的全景,有助于了解期刊之间在研究领域、学术思想上的联系。以CSSCI《大学图书馆学报》2000-2009年的数据为研究对象,采用文献计量学的方法,从自引率、自被引率和同被引等方面来研究期刊的引用认同,分析比较了《大学图书馆学报》与图书情报领域其它期刊的关系密切程度,同时还引进了新期刊扩散因子的概念作为期刊影响因子的补充指标,对《大学图书馆学报》进行分析和评价,揭示该刊的学术水平和办刊质量,为该刊今后的发展及研究提供参考数据。     

Chinese urban migrants' sense of place: Emotional attachment,identity formation,and place dependence in the city and community of Guangzhou

In this paper, we study urban migrants' sense of place in Guangzhou, China, focusing on the structural relations between place attachment, identification and dependence as the three key place dimensions. Through both quantitative structural equation modelling and qualitative analysis of in‐depth interviews data, our research suggests that migrants' sense of place demonstrates complex relationships between the three registers of emotional attachment, identity formation and functional dependence. The construction of sense of place is also related to the personal experiences of living as urban ‘outsiders’. Our research also reveals a striking difference between the city and community levels in terms of the ways in which migrants' sense of place is constructed. Urban migrants tend to exploit the functional utilities of microscopic urban spaces to meet their demands for recreation, education and socialisation. On the other hand, their sense of place to the city is largely compromised by their attachment to the hometown and conditioned by their personal identification to the city.     

新生代农民工的未来认同及其影响因素研究——基于青岛的问卷

根据对青岛某纺织厂的问卷调查和深度访谈,深入分析新生代农民工未来认同的现状及其影响因素。新生代农民工目前对市民身份有所期待,但认同度不高;对未来归属地有目标,但归属感不强烈,表现出期待与徘徊并存的现状。文章从制度政策、社会环境和新生代农民工自身3个方面进行影响因素的分析,并据此提出了提升新生代农民工未来认同的对策建议：改革城乡二元体制、改善社会环境,增强关爱与沟通、调整新生代农民工的心态,提升其素质。     

日本晚樱花器官特征基因ClAP1的克隆与表达分析

用同源克隆的方法和3′ RACE技术,从日本晚樱（Prunus lannesiana）中克隆得到了1个AP1同源基因ClAP1的cDNA全长。其cDNA全长1 005 bp,包括1个编码238个氨基酸共717 bp的开放阅读框。序列比对和分子系统发生分析表明,ClAP1是拟南芥的AP1同源基因,其蛋白质的C末端具有一个保守的euAP1模体。半定量RT-PCR分析表明,ClAP1在3个日本晚樱品种‘大岛’、‘一叶’和‘普贤像’的萼片、花瓣、雄蕊和雌蕊中均有表达,在叶中不表达,属参与花发育的转录因子,但其表达模式与拟南芥的AP1有一定差别。

Perceptions of cultural ecosystem services of tree-based green infrastructure: A focus group participatory mapping in Zagreb,Croatia

Urban green infrastructure provides city dwellers numerous benefits. Among them, cultural ecosystem services (CES) are distinguished by being easily perceived and essential for people and their well-being. However, not all CES are equally easy to perceive, resulting with some of the CES categories being weakly explored. Research on CES also rarely considers elements of urban green infrastructure other than parks and forests. Therefore, there is a lack of research on different components of urban green infrastructure, especially tree-based, perceived in relation to CES. This paper presents the results of focus group participatory mapping implemented with citizens in the city districts of Zagreb on the perception of five selected CES categories in various types of urban green infrastructure. Our results show that participants perceived 13 different types of tree-based urban green infrastructure as providers of CES. We also distinguish patterns in the perception of CES categories and their connection with types of tree-based urban green infrastructure. Tree lines are perceived as providers of aesthetical experiences. Furthermore, forests and park forests are perceived in relation to place attachment and recreational activities, while parks are versatile and provide all explored CES. Other types that emerged as important were greenways, greenery around residential buildings and educational institutions, which provokes rethinking of a careful planning of the entire repertoire of urban green infrastructure.     

Biological and molecular characterization of tomato brown rugose fruit virus and development of quadruplex RT-PCR detection

Tomato brown rugose fruit virus(ToBRFV) is a novel tobamovirus firstly reported in 2015 and poses a severe threat to the tomato industry. So far, it has spread to 10 countries in America, Asia, and Europe. In 2019, ToBRFV was identified in Shandong Province(ToBRFV-SD), China. In this study, it was shown that ToBRFV-SD induced mild to severe mosaic and blistering on leaves, necrosis on sepals and pedicles, and deformation, yellow spots, and brown rugose necrotic lesions on fruits. ToBRFV-SD induced distinct symptoms on plants of tomato, Capsicum annumm, and Nicotiana benthamiana, and caused latent infection on plants of Solanum tuberosum, Solanum melongena, and N. tabacum cv. Zhongyan 102. All the 50 tomato cultivars tested were highly sensitive to ToBRFV-SD. The complete genomic sequence of ToBRFV-SD shared the highest nucleotide and amino acid identities with isolate IL from Israel. In the phylogenetic tree constructed with the complete genomic sequence, all the ToBRFV isolates were clustered together and formed a sister branch with tobacco mosaic virus(TMV). Furthermore, a quadruplex RT-PCR system was developed that could differentiate ToBRFV from other economically important viruses affecting tomatoes, such as TMV, tomato mosaic virus, and tomato spotted wilt virus. The findings of this study enhance our understanding of the biological and molecular characteristics of ToBRFV and provide an efficient and effective detection method for multiple infections, which is helpful in the management of ToBRFV.
