Journal of Systems Engineering and Electronics 2007年第4期18卷 818-824页

Communication security is a critical aspect of QoS provisioning in wireless mesh network （WMN）. Because of the inherent characteristics of WMN, conventional security mechanisms cannot be applied. In order to guarantee the communication security, a novel communication security mechanism is proposed. The mechanism uses a communication encryption scheme to encrypt data packets and employs a risk avoidance scheme to avoid the malicious nodes during communications. Simulation results indicate that the mechanism is able to provide secure communication effectively and reduce the damage of attacks through multiple paths.

The accumulation of pathological α-synuclein(α-syn)in the central nervous system and the progressive loss of dopaminergic neurons in the substantia nigra pars compacta are the neuropathological features of Parkinson's disease(PD).Recently,the findings of prion-like transmission of α-syn pathology have expanded our understanding of the region-specific distribution ofα-syn in PD *** evidence suggests that α-syn aggregates are released from neurons and endocytosed by glial cells,which contributes to the clearance of α-***,the activation of glial cells by α-syn species produces pro-inflammatory factors that decrease the uptake of α-syn aggregates by glial cells and promote the transmission of α-syn between neurons,which promotes the spread of α-syn *** this article,we provide an overview of current knowledge on the role of glia and α-syn pathology in PD pathogenesis,highlighting the relationships between glial responses and the spread ofα-syn pathology.

清代书院的知识结构,大致包括"俗学"、"古学"、"新学"三个方面,即时文类书等应试之学、传统四部之学、晚清时务泰西之学。具体情形,可由书院的阅读指南和课业设置获知一二。书院士子的知识广度,主要体现在古学和新学方面,这在经史词章类、时务西学类课艺的题目中,有具体而直观的呈现。总体看来,清代书院提倡读经典为主、读类书为辅,反对庸烂时文和二手知识,对卑俗的应试学风有纠偏之功,有助于士子建构健全的知识体系;清代书院与科举的关系,是积极的良性互动,而不是消极的"附庸"。

《中国文学编年史》抽样分析

武汉大学学报（人文科学版） 2007年第2期60卷 194-199页

作者：鲁小俊中南财经政法大学新闻与文化传播学院湖北武汉430074

十八卷本《中国文学编年史》是迄今为止规模最大的中国文学编年著作。该书的总体特点可以由随机抽取的两个时间点——康熙四十三年甲申(1704)和嘉庆元年丙辰(1796)——窥知一二。

综合考察《清代朱卷集成》中有多份朱卷且所记生年不同的154人,并参考《清代官员履历档案全编》中的相关记载,可以发现:清代的官年歧异现象,以减岁为主导趋向,追求"年轻化";会试朱卷中的生年,较多地成为做官后年龄的"定本";也有曾以官年应试,后以实年做官者,但这只是少数人;官年与实年的岁差,多在数岁乃至十数岁,其中三四年、五六年,最为常见,七八年、九十年,也不在少数;同一人的多份朱卷,所记出生年份越早者越接近于实年。我们也可由此确定著录生年的一个原则:在没有其他传记资料佐证的情况下,宜以所记出生年份最早之朱卷为依据,简称"早岁优先"。

如聆謦咳:语录体与书院教学

语录体在书院教学活动中的运用大致有三种形态:引申先贤语录、记录师长讲论、拟想现场语境,可简称为“引言”“记言”“拟言”。在师长关于讲学、劝谕、训示的“独白”之外,语录体还有三种“副文本”,即“过场”语言和“旁白”“对白”... 详细信息

语录体在书院教学活动中的运用大致有三种形态:引申先贤语录、记录师长讲论、拟想现场语境,可简称为“引言”“记言”“拟言”。在师长关于讲学、劝谕、训示的“独白”之外,语录体还有三种“副文本”,即“过场”语言和“旁白”“对白”。语录体在书院教学中既体现出权威性和精粹性,又有平等化、生活化倾向。它再现或模拟了面对面的现场情境,营造出近距离的接受氛围,能让诸生和后学如聆謦咳。因此,历代书院将其作为教学文体,普遍运用且行之有效。
