Abstract As early as the 1830s, water was pumped from the lake above the city and led via a wooden pipe to the centre of Tampere. In the 1860s, a businessman suggested that a privately held waterworks be constructed, but a city-owned works was preferred. A gravity system began distributing water in 1882, followed by a high-pressure system in 1898. The first phase of a sewerage system was completed in 1894. The bodies of water upstream and downstream from the City of Tampere deteriorated during the 1950s and 1960s but recovered surprisingly fast after the introduction of efficient water pollution control. Groundwater utilization was suggested in the 1910s, implemented partly since the 1950s, and may be followed by artificial recharge by 2010. Experiences from both water supply and water pollution control in the case of Tampere indicates that foreign solutions as such do not suit Finnish conditions. Applied development and research are needed. The role of public relations and education is becoming increasingly important as we enter the 21st century. 相似文献

Electronic Data Interchange (EDI)—despite its basic simplicity—forms a complex and inter-organizational innovation. This necessitates multiple points of observation and the use of multiple theoretical frames in accounting EDI diffusion processes. Based on field study data we deliver a multi-level account of EDI diffusion in Finland. The study clarifies how factors located on three levels of analysis can be applied to understand the unfolding of EDI adoption in different organizational constellations, here called diffusion patterns. We examine three families of diffusion patterns: local dyadic patterns; industry-wide networks; and national initiatives. Overall we discern five distinct diffusion patterns. The analysis of the five patterns demonstrates that EDI diffusion is a complex interplay of organizational, industry and institutional factors. On the theory plane our study calls for the need to orchestrate multi-level approaches to study the diffusion of complex, and networked technologies. 相似文献

Holistic care is nothing new. There are well-known examples across the world and throughout history – from ancient Greece, China and India to early 20th-century northern Europe – of approaches that prioritise placemaking as a facilitator for health and healing. Inspired by such precedents, London-based architects Penoyre & Prasad produce buildings that engage with nature and help put patients back in control of their recovery process. Sunand Prasad , one of the firm's cofounders, explains. 相似文献

The Finnish Wind Atlas was prepared applying the mesoscale model AROME with 2.5 km horizontal resolution and the diagnostic downscaling method Wind Atlas Analysis and Application Programme (WAsP) with 250 m resolution. The latter was applied for areas most favourable for wind power production: a 30 km wide coastal/offshore zone, highlands, large lakes and large fields. The methodology included several novel aspects: (i) a climatologically representative period of real 48 months during 1989–2007 was simulated with the mesoscale model; (ii) in addition, the windiest and calmest months were simulated; (iii) the results were calculated separately for each month and for sectors 30° wide; (iv) the WAsP calculations were based on the mesoscale model outputs; (v) in addition to point measurements, also radar wind data were applied for the validation of the mesoscale model results; (vi) the parameterization method for gust factor was extended to be applicable at higher altitudes; and (vii) the dissemination of the Wind Atlas was based on new technical solutions. The AROME results were calculated for the heights of 50, 75, 100, 125, 150, 200, 300 and 400 m, and the WAsP results for the heights of 50, 75, 100, 125 and 150 m. In addition to the wind speed, the results included the values of the Weibull distribution parameters, the gust factor, wind power content and the potential power production, which was calculated for three turbine sizes. The Wind Atlas data are available for each grid point and can be downloaded free of charge from dynamic maps at www.windatlas.fi . Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

News coverage of climate change has increased in the English‐speaking industrialised countries since 2005. The development of news coverage, especially in the United States, has been widely studied. Knowledge of the development and contents of climate debate in other languages than English is sparse. This paper presents the development on the press news coverage on climate change in Finland during the period 1990–2009 and discusses different social, economic and ecological factors influencing the news coverage. 相似文献

This case study of VTT Building Technology comprehensively describes the reasoning, decisions and effects in the process of change caused by the transformation to improve the applicability of research results and to increase commercial income. The change in culture, management, organizational structure, organizational strategies and research, development and dissemination activities were designed to increase customer orientation, performance quality and effectiveness in all activities. The culture change from a scientific research community to a customer-oriented and flexible commercial organization is detailed. In addition to the deep vertical levels of knowledge gained from research, a horizontal capability is developed and promoted to provide applicable knowledge (know-how) in forms suitable to the Institute's customers. Clear targets for achieving the Institute's mission and financial performance have been established to gauge progress and provide incentive for rewards. VTT Building Technology a mene cette etude de cas qui decrit de maniere exhaustive le raisonnement, les decisions et les effets du processus de changement induits par la transformation visant a ameliorer les applications des resultats de la recherche et a accroitre les recettes commerciales. Les changements qui affectent la culture, la gestion, les structures et les strategies d'organisation, la recherche et le developpement ainsi que les activities de dissemination ont ete penses afin d'orienter davantage le client, et d'ameliorer le niveau de qualite et l'efficacite de toutes les activities, L'auteur etudie en detail le changement de culture provoque par le passage d'une communaute de recherche scientifique a une organisation commerciale souple et orientee "client". Outre les niveaux verticaux profonds de connaissance issus de la recherche, il se developpe une capacite horizontale que l'on encourage pour fournir des connaissances (savoir faire) applicables et presentees dans des formes convenant a la clientele de l'Insitut. Des objectifs financiers et de programme precis ont ete fixes a l'Institut pour que l'on puisse evaluer les progres et motiver les travaux par des recompenses. 相似文献

District heating companies’ efficiency of providing district heating to small houses in Finland and Sweden is studied. The method used is Data Envelopment Analysis (DEA). The results indicate that Finnish companies, overall, are more efficient when offering district heat to small house customers. In Finland, price increases demand and impacts district heating company efficiency the most. The lower price level in Finland, compared to Sweden, might be a reflection of competition between different heating goods. In Sweden, network size and company size (large companies are more efficient in providing small houses with heat than small ones) drive the efficiency of small house district heating. 相似文献

Abstract.
Europe once was the most important mining region in the world and nearly every European country has remnants of historic and even pre-historic mining sites. Though the importance of mining activities in most European countries declines, the abandoned sites are still there and can cause environmental dangers as well as technological challenges. On the bases of selected European countries and case studies, these dangers and challenges are described and potential solutions are illustrated. 相似文献

Knowledge of underwater morphology is an essential component of many hydrological and environmental applications such as flood modelling and lotic habitat mapping. Remote sensing allows modelling of bathymetry at spatial scales that are impossible to achieve with traditional methods. However, the use of passive remote sensing for modelling water depth in fluvial environments remains a challenge. Different methods of computing bathymetry models based on remotely sensed imagery combined with ground measurements for calibration were investigated in order to produce a digital bathymetry model of a reach of the river Tana in Lapland. An empirical deep water correction model was evaluated together with theoretical hydraulically assisted bathymetry (HAB) models. The empirical model produced good results, correlating to known depths at 0.98 (R 2 = 0.96) with a mean error of ±12.0 cm. It was demonstrated that usable levels of accuracy can be achieved with data that had previously been considered unsuitable for bathymetry modelling. Some issues related to channel substrate were addressed. The models based on hydraulic theory were tested for the first time outside the area they were developed in. Both models were found to be rather sensitive to certain assumptions, such as the channel friction parameter. The HAB models are able to produce relative depth estimates that can under certain conditions approach actual depths at accuracies similar to the empirical model. Extensive accuracy assessment was performed in order to evaluate the vertical as well as the spatial accuracy of the three models. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献
