基于整体性视角的社区更新：框架、模式与案例 — —以佛山桂华邨社区为例

现行的政府单一主导、政府与开发 商合作的社区更新模式与业主的自主更新需 求产生了矛盾。针对现有研究对社区更新的 系统性缺乏关注的问题，本文从整体视角出 发，通过构建“参与主体—程序设计—法规 政策—资金调配”四维框架，分析现行社区 更新模式与业主自主更新需求产生冲突的内 在机制。在优化现有模式的基础上，提出三 种适应业主自主更新需求的理论模式。桂华 邨业主自主更新失败的实践案例证明了本文 所提出的四维框架的重要性。最后，从政府 视角对我国社区更新机制提出优化建议。     

Public perceptions on artificial intelligence driven disaster management: Evidence from Sydney,Melbourne and Brisbane

In recent years, artificial intelligence (AI) is being increasingly utilised in disaster management activities. The public is engaged with AI in various ways in these activities. For instance, crowdsourcing applications developed for disaster management to handle the tasks of collecting data through social media platforms, and increasing disaster awareness through serious gaming applications. Nonetheless, there are limited empirical investigations and understanding on public perceptions concerning AI for disaster management. Bridging this knowledge gap is the justification for this paper. The methodological approach adopted involved: Initially, collecting data through an online survey from residents (n = 605) of three major Australian cities; Then, analysis of the data using statistical modelling. The analysis results revealed that: (a) Younger generations have a greater appreciation of opportunities created by AI-driven applications for disaster management; (b) People with tertiary education have a greater understanding of the benefits of AI in managing the pre- and post-disaster phases, and; (c) Public sector administrative and safety workers, who play a vital role in managing disasters, place a greater value on the contributions by AI in disaster management. The study advocates relevant authorities to consider public perceptions in their efforts in integrating AI in disaster management.     

寒冷地区某既有办公建筑围护结构优化改造研究

既有公共建筑能耗中,围护结构节能潜力巨大。以兰州某既有办公建筑为例,采用DeST-C软件模拟围护结构不同材料厚度、窗型,得出系列负荷,通过对数据分析、比较,得出如下结论:外墙外保温适宜材料为50mm的挤塑板,最大热负荷节能率为45.66%;屋面适宜保温材料为65mm的挤塑板,最大热负荷节能率为4.25%;外窗各个朝向全部更换玻璃,推荐选用内张膜中空玻璃(双膜),最大热负荷节能率为7.36%;单独更换南向外窗材料,推荐选用真空镀膜复合中空玻璃,最大热负荷节能率为1.78%。     

Public-sector reform: Lessons from the privatisation experiment in Greece

This paper explores the process of public sector reform in Greece through the lens of privatisation. It is suggested that the transformation of the domestic post-war interventionist state into the current market-oriented paradigm has been disrupted and dependent on changing reform rationales. Along with the effect of historical dynamics on the direction and scale of change, the explanatory power of external determinants of reform is stressed. Findings reflect a direct linkage between the intensity of external pressure and the pace of reforms. The sustainability of gradual privatisation reforms seems more certain than the outcomes of fast-track privatisations under policy conditionality.     

A New NTRU-Type Public-Key Cryptosystem over the Binary Field

As the development of cloud computing and the convenience of wireless sensor netowrks, smart devices are widely used in daily life, but the security issues of the smart devices have not been well resolved. In this paper, we present a new NTRU-type public-key cryptosystem over the binary field. Specifically, the security of our scheme relies on the computational intractability of an unbalanced sparse polynomial ratio problem (DUSPR). Through theoretical analysis, we prove the correctness of our proposed cryptosystem. Furthermore, we implement our scheme using the NTL library, and conduct a group of experiments to evaluate the capabilities and consuming time of encryption and decryption. Our experiments result demonstrates that the NTRU-type public-key cryptosystem over the binary field is relatively practical and effective.     

PKI/CA技术综述

公开密钥基础设施(PKI)是解决网络安全的技术．典型PKI应用系统包括安全Web、注册机构(RA)、认证机构(CA)、目录(LDAP)和数据库等服务器．RA验证客户证书申请后提交CA．CA检查信息完整和数字签名正确后把证书存放到证书库和目录服务器，并将签发证书序列号通知客户和RA．客户即可使用该号通过目录服务器下载证书．1993年以来，美、加、欧洲、韩、日等国已相继展开PKI研究．我国2001年将PKI列入十五863计划，并着手解决PKI标准化、CA互联互通等关键技术问题。

Sociotechnical systems, risk management, and public health: comparing the North Battleford and Walkerton outbreaks

Accidents in different complex sociotechnical systems are rarely compared using the same theoretical framework for risk management. We conducted a comparative analysis of two Canadian public health disasters involving drinking water distribution systems, the North Battleford Cryptosporidium parvum outbreak in April 2001 and the Walkerton E. coli outbreak in May 2000. Both accidents resulted from a complex interaction between all levels of a complex sociotechnical system. However, the low-level physical and individual factors differed in the two cases, whereas, the high-level governmental and regulatory factors tended to be the same. These findings may have implications for the design of public policies to minimize risk in complex sociotechnical systems.     

Public Attitudes to In-House Water Recycling in England and Wales

This study, which is based on responses from over 300 individuals in England and Wales, explores how a willingness to use a water-recycling system of specific configuration varies against a number of factors which are linked to system design, system scale, system context, and water-conservation behaviour. Findings show that there is broad willingness to accept in-house water recycling provided that public health is not compromised.     

Awards for Distinguished Contributions to Psychology in the Public Interest: 1986.

The awards for Distinguished Contributions to Psychology in the Public Interest recognize persons who, in the opinion of the Committee on Public Interest Awards, have advanced psychology as a science and/or profession by a single extraordinary achievement or a lifetime of outstanding contributions in the public interest. These contributions might include the identification or solution of significant social problems; unusual initiative or dedication to activity in the public interest; or the integration of the science and/or profession of psychology with social action in a manner beneficial to all. The Committee is authorized to present two awards per year, each with a prize of $2,000. The second award, for which recipients may not have held a Ph.D. for more than 15 years, was established to recognize the large number of excellent psychologists who have made significant contributions to the public interest during the early stages of their careers.
