Working with children as stakeholders in development: the challenges of organisational change

This article considers the challenges of promoting children's participation in development programming. It argues against the tendency to see the main obstacle to achieving this aim as technical. Instead it explores the institutional dimensions of change that may be required. The experience of a four-year process of training and organisational review within Save the Children Denmark provides the substance for reflection about the kinds of cultural and structural change that are implicated in enabling a development organisation to become capable of engaging young people as stakeholders in a meaningful and sustainable manner.     

成年牦牛支气管动脉的组织结构观察

运用组织学方法对成年牦牛肺支气管动脉的组织结构进行了研究与分析,以探索支气管动脉对高原低氧环境的适应性结构。支气管动脉分布于支气管、胸膜、淋巴结、小叶间隔、肺动脉与肺静脉外膜、迷走神经鞘膜及气管腺周围,其中膜厚度占外径百分率MT(%)的均值为(33.30±11.03)%。肺外支气管动脉内皮下层无纵行平滑肌束,但进入支气管壁后其内弹性膜分叉并包绕纵行平滑肌束;中膜平滑肌结构较致密,外膜中含纵向螺旋状排列的胶原纤维束和弹性纤维。小支气管黏膜固有层中含有大量的支气管小动脉,数量可达(120±51)条/mm2。虽然黏膜固有层与外膜中的支气管动脉管径相差较大,但中膜平滑肌的厚度却很相近。可见,成年牦牛肺内支气管动脉管壁中的平滑肌含量非常丰富,是一种对低氧环境的适应性结构,表明低氧对牦牛肺有一定的影响。     

MAP-2在大鼠脑损伤后表达变化的时间规律性研究

目的探讨MAP-2在大鼠脑损伤后表达变化的时间规律性。方法以355.09kPa冲击应力致大鼠局灶性脑损伤后,在不同时间应用原位杂交、免疫组化、免疫组化双染色技术检测MAP-2 mRNA和蛋白表达情况。结果 MAP-2mRNA在对照组及假手术组均有表达,伤后30 min表达增强,伤后2d,达到峰值,并维持高水平表达至伤后7d。MAP-2蛋白在对照组及假手术组均有表达,伤后3h开始呈下降趋势,伤后1d,达到最低值,伤后2d起,表达逐渐恢复,伤后15d,恢复至对照组水平。结论脑损伤后MAP-2 mRNA及蛋白表达具有时间规律,可用于法医学推断脑损伤形成时间。     

录像制品性质初探

我国《著作权法》规定了影视作品和录像制品,并对它们分别赋予著作权与邻接权的保护。本文通过对基本概念的检视,发现现有录像制品的概念中暗藏矛盾,进一步分析产生这种矛盾的原因,同时重新审视了独创性标准和邻接权制度,提出可以尝试用视听作品的概念统一影视作品与录像制品。希冀在我国《著作权法》第三次修订进行调研工作的大背景之下,对重新定位著作权法中的录像制品提供一种有益的尝试。     

Forensic investigation of OOXML format documents

MS Office documents could be illegally copied by offenders, and forensic investigators still face great difficulty in investigating and tracking the source of these illegal copies. This paper mainly proposes a forensic method based on the unique value of the revision identifier (RI) to determine the source of suspicious electronic documents. This method applies to electronic documents which use Office Open XML (OOXML) format, such as MS Office 2007, Mac Office 2008 and MS Office 2010. According to the uniqueness of the RI extracted from documents, forensic investigators can determine whether the suspicious document and another document are from the same source. Experiments demonstrate that, for a copy of an electronic document, even if all the original characters are deleted or formatted by attackers, forensic examiners can determine that the copy and the original document are from the same source through detecting the RI values. Additionally, the same holds true if attackers just copy some characters from the original document to a newly created document. As long as there is one character left whose original format has not been cleared, forensic examiners can determine that the two documents are from the same source using the same method. This paper also presents methods for OOXML format files to detect the time information and creator information, which can be used to determine who the real copyright holder is when a copyright dispute occurs.     

建设工程领域拖欠农民工工资责任主体分析

近年来拖欠农民工工资问题愈演愈烈,不仅使农民工辛苦的血汗钱化为泡影,生活得不到保障,而且严重扰乱建筑市场的秩序,严重违反了公平原则,社会影响恶劣,亟需解决。但在我国现行的法制体系下,农民工只能向与其有直接劳动关系的单位或组织主张支付工资的请求,而不能向与其有间接联系的发包方、工程总承包方主张支付工资请求权,不利于保护农民工的利益。这一切源自于合同相对性的限制,合同相对性就表现在主体的相对性、内容的相对性以及最重要的是责任的相对性,但是我国不乏有突破这一原则的立法例。将这些突破归结到一点,可以发现突破点就在于满足实现社会实质正义的需要,将法律的天平倾向于保护社会弱势群体,以形式上的不平等实现实质的正义,将拖欠农民工工资的责任落实到实处,将发包方和工程总承包方纳入到责任体系,以切实解决我国这一关乎民生的问题。     

Can markets be expected to prevent themselves from self‐destruction?

Even if competitive markets have shown themselves to be the most efficient organizational form for creating economic efficiency, the question of how they can avoid destructive influence from agents with opportunistic motives remains unresolved. Different institutional approaches have argued that to be efficient, markets need to be embedded in a set of formal and informal institutions. Because such institutions will in the long run make all market agents better off, they are labeled efficient institutions. Contrary to what is argued in neoclassical economics, it is unlikely that such institutions will be created endogenously by market agents because the institutions are to be understood as genuine public goods. Moreover, if such institutions have been established, we should expect market agents to face a collective action problem when sustaining them, leading to the destruction of the institutions. The conclusion is that if left to themselves, markets should be understood as inherently self‐destructive.

司法公正与司法权的国家本位

司法公正是司法活动的本质要求,是法院和其他司法机关所追求的根本目的.司法权的国家本位是一种国家完全主导司法活动的"司法状态".司法权的国家本位对司法公正的影响是深重的.它使"无讼是求"成为主流的司法文化,也使得司法活动不重程序,司法活动和司法制度过分强调国家和社会"秩序".要真正实现司法公正,必须适当调整司法权的国家独占,让社会和公民在司法活动中发挥更重要的作用.
