Parental Cultural Socialization of Mexican‐American Adolescents’ Family Obligation Values and Behaviors

The current study examined how parents’ cultural socialization efforts contribute to adolescents’ family obligation values and behaviors and how these processes may depend upon the relational climate at home. Utilizing survey and daily diary methodologies, 428 Mexican‐American adolescents (50% males; M_age = 15 years) and their parents (83% mothers; M_age = 42 years) participated in the study. Adolescents reported on their family obligation values and engagement in family assistance tasks across 14 days. Parents reported on their cultural socialization practices. Results indicated that parental cultural socialization was associated with adolescents’ family obligation values and behaviors when parent–child relationships were low in conflict and high in support. Findings suggest that the transmission of cultural values and practices is best facilitated through positive parent–child relationships.     

论当代大学生全球化意识的培养

全球化背景下多元文化的碰撞和激荡使90后的大学生容易陷入身份认同危机。顺应全球化语境,培养大学生的全球化意识实质上是构建一种基于尊重传统文化基础之上的多元文化认同与适应。承认不同文化的普同特性是培养大学生全球化意识的基础;建立以高度的文化自觉和广泛的文化认同为基础的文化安全是保障,最终目的是形成一个和谐发展的文化生态系统。     

改革开放40年乡镇民间体育组织的历史变迁与启示——以G镇为个案的实证考察

采用个案分析、实地调查、口述史记录等研究方法，考察了改革开放40年安徽省G镇民间体育组织演变的历史脉络与特征，在此基础上对我国乡镇体育组织变迁进行了理论探索。研究认为改革开放40年G镇民间体育组织经历了恢复初建期（1978-1991年）、快速成长期（1992-2001年）和蓬勃发展期（2002-2018年）三个阶段的流变过程。G镇民间体育组织变迁对我国乡镇体育组织发展的启示是：传统与现代融合是乡镇体育组织发展的文化诉求；国家与社会互构是乡镇体育组织发展的主体关系；走向"善治"是未来乡镇体育组织发展的治理理念。     

Universities and the humanities,then and now

Over the centuries, universities have functioned as gatekeepers and treasurers of received knowledge, while concomitantly furthering innovative contributions to society. Yet, when cultivating research ‘silos’, universities encourage scholars to explore in seeming isolation. Out of such tensions, universities have supported, and will continue to pursue, different kinds of, and approaches to, furthering knowledge and creativity. In the past, the humanities had been central to this mission. More recently, however, the efficient and global acceleration of consumer-oriented ‘knowledge production and consumption’ seems to form a critical factor upsetting the centrality of the humanities in university cultures. In this context, exploring the academic communities of the late middle ages proves to be a useful exercise. Forged in strong relationships with ecclesiastical and secular powers, mediaeval universities nonetheless share critical concerns with today’s academic institutions; thus, they too were constrained by the need to attract and exact excellence, to navigate relationships with their immediate environs, and to train professionals, who could ensure continuity in academic communities, the church, and the imperial courts. In other words, mediaeval universities also experienced polarising tensions that reveal consonances between then and now and that can gloss today’s acceleration driving the consumer model of knowledge production and consumption, while also encouraging scholars to form more explicit links to external constituencies.

跑台训练增强大鼠的学习记忆及其海马BDNF基因表达

目的:探讨8周跑台训练对大鼠学习记忆能力及其海马内脑源性神经营养因子(BDNF)基因表达的影响。方法:将24只雄性SD大鼠分为对照组(C组,n=8)和训练组(T组,n=16),T组进行8周的跑台训练。通过Y迷宫实验,所有大鼠在第7周进行学习能力测试,在第8周进行记忆能力测试。第8周最后一次训练后,随机将T组分为T1组(n=8)和T2组(n=8)。T1组训练后即刻与C组同时断头处死,两组交叉进行,T2组在训练后24时断头处死,采用RT-PCR法检测各组大鼠海马内BDNF的基因表达水平。结果:Y迷宫测试表明T组大鼠的学习记忆优于C组;与C组相比,T1组和T2组大鼠海马中BDNF的基因表达水平均显著升高(p<0.01)。结论:8周跑台训练可增强大鼠的学习记忆能力,这与海马内BDNF基因表达的增加有关。     

论网络空间中的语言暴力

网络的发展带来了舆论空间的革命性拓展,但随之也产生了语言暴力等消极言论现象。这一现象产生的原因是多方面的,突出反映在网络语言暴力主体及客体的特定性、网络发言语境的群居性、社会怨恨心理的影响等方面。     

对称铣削系统协同运动位姿误差预测与补偿算法

针对对称铣削系统在加工过程中会出现协同位姿误差的问题,提出一种考虑温度变化的对称铣削系统协同位姿误差预测与补偿方法。在恒温条件下,将对称铣削系统的工作空间划分为平动轴运动空间和旋转轴运动空间,提出一种在采样点误差已知情况下的误差预测算法|在变温条件下,通过测量分析对称铣削系统的热误差,提出一种能够快速确定任意温度下系统误差的方法。在误差补偿方面,提出一种递归算法补偿系统误差,并在对称铣削系统上进行实验。结果表明,在恒温条件下,补偿后的协同位置精度及姿态精度分别提高了78.42%和 57.03% ,在变温条件下分别提高了 79.14%和 62.79%,验证了该算法的有效性。
