论江桥之战标志着我国抗日战争的开始--纪念中国抗日战争胜利60周年

学术界在抗日战争开始的问题上一向存在着异议.本文以史实为根据既论证了江桥之战是当时黑龙江省政府所策划的有领导、有组织地正面抗击日本侵略的战争,并考证出其确实得到了中国政府的授权和支持而具有了民族抗战的性质;又重新评价了其在抗日战争的重要地位和作用,堪称中国抗战中局部抗战的第一战,因而标志着中国抗日战争的开始.同时,也澄清了作为新民主主义革命时期第三阶段的"抗日战争"和中国全面抗日战争与作为那场重大历史事件的"抗日战争"之不同内涵,也即所谓的新民主主义革命时期第三阶段和全面抗战阶段"八年"说与中国抗日战争持续时间多长是两个性质不同的问题,从而对"抗战八年"的说法提出了质疑和批评,并代之以"抗战十四年"的概念.最后的结论是江桥之战的爆发日就是中国抗战的开始之时.     

‘The confidence to know I can survive’: resilience and recovery in post-quake Christchurch

This paper explores the relevance of terms such as resilience and recovery when analysing earthquake stories recorded for the Women's Voices/Ngā Reo o Ngā Wahine Project after the sequence of earthquakes and aftershocks in Christchurch, New Zealand's second-largest city, in 2010–2011. While the media focused on stories of victims, the heroic work of rescue teams, policy, army and firefighters, or the deliberations of national and local politicians, the National Council of Women of New Zealand wanted to ensure that women's everyday quake experiences were recorded for posterity. The outcome was an oral history project that documented the stories of women all over the city, both beneficiaries of earthquake support and those active in assisting others. Their narratives illustrate how resilience in the face of natural hazard events, such as this earthquake sequence, requires effort, ingenuity and imagination, but also the activation of multiple actor networks and relevant technologies. These ‘insider stories’ also highlight the ways in which expectations of ‘resilience’ can obscure vulnerability after natural hazard events and the complex and uneven processes associated with ‘recovery’. The relevance of critical reflections on discourses of resilience is explored through attention to the stories of specific women.     

HEALTH CARE INFLATION AND ITS IMPLICATIONS FOR MONETARY POLICY

Motivated by recent findings on the cyclical movement of both health and health spending, we construct a general equilibrium model that distinguishes health care demand from the demand for other goods. Using this model, we are able to generate inflation dynamics and cyclicality of health that match the US data. When the model is subjected to an expansionary monetary policy shock, it yields different output and inflation responses compared with a two‐sector model with homogeneous demand. We show that the trade‐off between leisure and health spending plays an important role in model dynamics. The model further predicts different degrees of inflation stabilization across sectors when a shift in the monetary policy occurs. (JEL E52, E31, E32, I10)     

嘉庆朝军机处规制的完善与成熟

嘉庆朝是清代军机处各项规制最终定型并完善的时期，但学界对此论述却语焉不详。本文从军机处自身发展角度出发对该时期的军机处进行了考察，分别从分军机大臣的人数及选任资格、军机章京职责与考选、军机处基本职掌这三个方面详细论证该时期军机处的阶段性特点。     

一种基于正交小波变换的盲水印算法

提出了一种新颖的以灰度图像为水印的数字水印算法.首先利用正交小波变换对原始图像进行分解,然后借鉴传统的叠加思想,根据小波变换后,高低频分量的特点,将图像水印嵌入到小波域的低频部分.由于整个嵌入过程中,对原始图像没有进行任何改变,因此绝对保证了原图像的质量.水印的嵌入和提取都在密钥控制之下,可以较好地解决版权争议等问题.实验结果证明该算法对常见的图像处理操作和几何攻击有很强的鲁棒性.     

以数据流特性为导向的令牌调度算法

基于用于可扩展性强的高性能交换机中的多级结构,针对大部分以结构为导向,使用两次调度算法将数据“推”向输出的调度算法,提出了一种以数据流特性为导向的分布式调度算法,该算法支持多级高性能交换机的定长、变长分组交换,从输出端口将数据包从输入端口中“拉”出来．仿真结果表明,在均匀流的作用下,该系统能够达到100％的吞吐率、具有较小的时延,并能方便地支持负载均衡．
