Is construction procurement a key to sustainable development?

Has specialization of professional roles obstructed the holistic approach and sustainable development? A preliminary survey in Botswana involving construction professionals found that existing procurement systems have not integrated the efforts of the different project participants and also fail to fulfil the expectations of the users. A holistic approach involving the re-integration of construction disciplines by applying new procurement methods is proposed. An integrated, holistic way of working could provide a number of synergies through the consideration of the building project as an entire system. The implications include better decision making upstream, more efficient use of resources and the mitigation of negative environmental effects downstream.

La specialisation professionnelle est-elle un obstacle a l'approche globale et au developpement durable? Une etude preliminaire menee au Botswana et portant sur les metiers de la construction a revele que les systemes d'approvisionnement actuels n'integrent pas les efforts des differents participants a un projet et ne repondent pas aux attentes des utilisateurs. Cet article propose une approche globale dont le succes repose sur la reintegration de ces metiers et sur de nouvelles methodes d'approvisionnement. Une methode de travail integree et holistique, ou un projet de construction serait considere comme un systeme complet, pourrait faire naitre un certain nombre de synergies. Cette hypothese exige un meilleur processus decisionnel en amont une utilisation plus efficace des ressources et l'attenuation des effets negatifs sur l'environnement en aval.     

Sustaining Rural Landscapes: the role of integrated tourism

The aim of a European Union-funded research project entitled 'Supporting and Promoting Integrated Tourism in Europe's Lagging Rural Regions' (SPRITE) is to analyse and develop the potential for better-integrated tourism in the rural landscapes of Europe. Integrated tourism can be defined as that which is explicitly linked to the localities in which it takes place and, in practical terms, has clear connections with local resources, activities, products, production and service industries, and a participatory local community. Enhancing the sustainable economic potential of rural landscapes requires partnerships among rural people and the sustainable yet productive use of rural resources. A 'culture economy' approach to integrated tourism is proposed, which emphasizes the importance of local identity, the strategic commodification of resources and of place, and the importance of extra-local forces in enabling local activities. It is suggested that this approach may represent a shift beyond more traditional approaches to rural development.     

黄河中游多沙粗沙区水沙控制途径的探讨

根据黄河中游多沙粗区暴雨洪水及产流产沙特点，提出了为控制水沙危害，黄河中游治理应分两步走的战略。第一步解决近期水沙控制和耕地问题，主要措施是建设淤地坝和骨干坝。研究表明，在现状坝地，梯田条件下，为满足粮食生产需要，每平方公里需新增坝地３．１８ｈａ，且能港口控制水沙的要求。第二步是进行坡面治理，改善生态环境，以达到根治水沙的目的。

Only connect: teaching, technology and telesis

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.     

Product Platform Identification and Development for Mass Customization

This paper is mainly concerned with the Identification of an embryonic product platform from a family of products whose composition, configuration and characteristics are represented by Attributed Graphs. The problem becomes that of identifying the largest isomorphic sub-graph with the highest similarity. An algorithm is proposed for solving this problem together with several novel concepts.     

测定地下水流向的多计数管探头的研制

多计数管流向探头;;单孔;;总流向;;局部流向;;滤水管 掌握地下水的流动方向,有助于研究地下水的运动规律。利用放射性单孔法可以测定地下水流某一点流动方向。 应用放射性指示剂在单孔中测定地下水流向的方法由奥地利的梅尔霍费于1963年首先提出,1964年波兰的鲍劳斯齐克等把这种方法用于现场测量。放射性单孔流向测量方法有若干种,其原理基本相同,仅测量装置结构有区别,早期有单管旋转式探头。我们从1983年7月
