对技术定义的思索

技术的定义不是唯一的 ,可以从技术的来源、技术与科学的对应性、技术与人的关系、系统论几个不同的角度给技术下定义 ,这些定义从不同侧面揭示了技术的本质 ,各有各的用途 ,各有各的适用范围。这种给技术下定义的方法也为给其他概念下定义提供了有益的借鉴与启迪。     

The problem of definition expansion and contraction

This article is the fourth of a series of articles discussing various open research problems in automated reasoning. The problem proposed for research focuses on finding criteria that would enable an automated reasoning program to expand or contract definitions wisely. For evaluating a proposed solution to this research problem, we include suggestions concerning possible test problems.This work was supported by the Applied Mathematical Sciences subprogram of the Office of Energy Research, U.S. Department of Energy, under contract W-31-109-Eng-38.     

The role of the American Board of Professional Psychology in professional mobility.

This article describes the role of certification by the American Board of Professional Psychology (ABPP) in easing the process by which psychologists move beyond their original jurisdictional boundaries to practice psychology. Meeting the requirements for licensure or certification in the various jurisdictions can be a difficult task because these requirements vary considerably from jurisdiction to jurisdiction. Other mechanisms that are available to facilitate this process include the Certificate of Professional Qualification in Psychology issued by the Association of State and Provincial Psychology Boards and certification by the National Register of Health Service Providers in Psychology. The ABPP certificate/diploma has been regarded by many state psychological associations and state boards of psychology as an appropriate way in which to recognize psychologists who are eligible for licensure/certification in a jurisdiction because of the examination requirements for board certification.

Contemporary approaches to certification of measurement provision software

Contemporary approaches to the certification of measurement provision software are considered in domestic and overseas publications. Normative documentation is analyzed and a scheme is proposed for certification that takes account of the features of programs used for metrological purposes. __________ Translated from Izmeritel’naya Tekhnika, No. 5, pp. 65–68, May, 2007.

Important features of Iris OSQL

OSQL is the object-oriented database language developed for the Iris object-oriented database management system at Hewlett-Packard Laboratories. Its three fundamental constructs are objects, types, and functions. This paper provides an overview of the underlying concepts and some important features of OSQL.     

Service life planning and performance requirements

Service life planning comprises a model for the determination of a reasonable expected service life for buildings and components, and it establishes a routine for the assessment of design alternatives. A design option is considered reasonable when it meets or exceeds performance requirements over time that have been drawn up specifically for the specific project. Due to this assessment reference, there is a very evident link to the concept of performance-based building. Any stakeholder involved in the value chain or in the design process of the building, as well as regulators and building users, can express performance requirements. Identified requirements, both in relevance and in quality, will vary with the stakeholder and his/her perspective of interest. As building sector manufacturers develop most products with reference to standards rather than with reference to specific requirements, there is no direct link from user requirements to the product design. Instead, the building designer has the responsibility to ensure performance requirements are met by the performance of products integrated into the design. As these design decisions also have to be made at the material and component level, a performance-based building would benefit from an established rationale that enables the communication of performance requirements across the relevant system levels in the relevant design processes. A path for the connection of the established concepts of service life planning and performance-based building is presented. The aim is to identify key elements that need to be developed for the successful linkage of performance-based building with service life planning.     

水源涵养内涵及估算方法综述

水源涵养和生态系统过程与人类生产生活紧密相关,深入研究水源涵养对维持生态系统健康和人类社会可持续发展至关重要,对促进人与水和谐共生具有指导意义。随着对水源涵养研究与应用的深入,水源涵养内涵逐渐丰富,评估方法愈加多样,但以往的研究中水源涵养定义模糊,缺乏对各种评估方法的综合性对比分析,因此急需明确界定水源涵养内涵,分析各种估算方法的适用性。采用文献分析法系统梳理水源涵养研究历程,将其划分为认识与萌芽期、理论发展期、定量计算和模型综合评估等4个阶段;从定义、水量与功能等3个方面明确界定水源涵养内涵,从原理、时空尺度、适用范围及优缺点方面对已有水源涵养量估算方法进行对比和分析,并展望水源涵养研究的未来发展方向。
