一种智能算法在起火部位判定中的应用

针对火灾事故多发,火灾原因多样化、复杂化,火灾调查工作缺少有效、直观技术手段的现实状况,提出了一种基于吸引力模型和弹性作用力模型,用于判定火灾现场起火部位的辅助智能算法,并利用Java语言开发了火灾现场起火部位辅助识别系统以实现算法的人机交互。通过已认定火灾案件进行的可行性验证表明,算法准确可靠,对于重建、模拟和分析真实火场信息,帮助火灾现场调查人员准确认定起火点,提高火灾调查分析的效率,科学准确地认识、理解火灾痕迹特征具有重要的现实意义。     

The cost of managerialism in the university: an autoethnographical account of an academic redundancy process

This paper presents an autoethnographical account of the events associated with the author’s redundancy from a tenured academic position at Murdoch Business School, Murdoch University, Perth, Western Australia. It is argued that managerialism, a social philosophy that sees the management of a university to be little different from the management of a for-profit business, provided university management with a rationale for a course of action that imposed heavy costs on individuals and undermined core academic values. The apparent weakness of the protection provided by tenure is highlighted by the mechanisms through which university management exerted control over the academic employment relationship. The cost of imposing management’s will to win at all costs corrodes valuable aspects of academic work, such as collegiality, trust and the sharing of information. The paper shows that the various mechanisms of control imposed by a university management that adheres to managerialist principles can destroy much of what is worthwhile in the university. What is left is something with little spirit and nothing worthwhile to manage.

Estimating the economic value of libraries

The authors are economists working for the Australian consultancy, SGS Economics & Planning in Melbourne. In 2011, the company produced a report for the State Library of Victoria on the value of libraries. Shishir Saxena and Andrew McDougall were responsible for the research that went into this report.     

Nitrogen addition delays the emergence of an aridity-induced threshold for plant biomass

Crossing certain aridity thresholds in global drylands can lead to abrupt decays of ecosystem attributes such as plant productivity, potentially causing land degradation and desertification. It is largely unknown,however, whether these thresholds can be altered by other key global change drivers known to affect the water-use efficiency and productivity of vegetation, such as elevated CO₂ and nitrogen(N). Using >5000 empirical measurements of plant biomass, we showed that crossing a...

Revisiting an information infrastructure for development: exploring the cost of information in Pacific Island development

Information and communication technologies (ICTs) have been associated with development programmes for many decades. A theme of Lamberton’s commentary on such initiatives focuses on the lack of attention given to information as a key factor in the development process. His writing reiterated a number of arguments that he saw as being fundamental to the application of an information perspective to development issues. With a focus on agricultural development policy in the Pacific region, the paper uses a number of propositions that are suggested by Lamberton to analyse contemporary development initiatives in Pacific Island agriculture. These propositions focus attention on information costs that can influence the transfer of information and development of knowledge. Document analysis of selected published sources from a Pacific Island development programme are reviewed to illustrate the significance of information costs for development processes. The paper addresses the contention between traditional authority and knowledge and its significance for development.

对我院电工电能新技术发展的几点想法

我院的电工研究队伍在全国电工事业的发展中起着重要作用,做出过重大贡献。现在想就今后20年或在更长的时期内如何发挥更大的作用(特别是我身处的电工研究所)谈几点想法。我院电工学科建设仍应坚定不移地以电工电能新技术为主要方向,另根据最近国家中长期科学与技术发展规划战略研究与讨论的情况和我院已有的基础,近期内应重点考虑超导电工、电气化交通、新能源发电等几个方面。(1)超导电工上世纪60年代初实用超导体出现后,我院于60年代后期开始了超导电工研究,70年代末超导电工定为我院电工研究领域的三个重点发展方向之一,以超导磁体技术…

云制造下厂商成本、用户成本鸿沟跨越

长期以来,厂商与用户之间存在的成本鸿沟被认为难以跨越,然而,随着云制造等新制造模式的兴起,构建跨组织成本协同机制成为厂商与用户的合作主导关系面临的关键问题。从产品制造为核心的商业模式刚性、竞争为主导的企业边界、产权鸿沟下市场机制的局限、决策代理人利己选择等多维度,对传统制造环境下的厂商成本与用户成本鸿沟形成机理进行解析,提出以价值生态系统为内核、推进产品与服务一体化、构建动态契约合作机制以及"连接红利"的跨界成本协同平台为路径的厂商成本、用户成本协同模型,为云制造环境下跨组织的成本优化提供理论框架,并通过案例分析对理论框架进行验证。
