Abstract The World Wide Web (WWW) has a decentralized information environment and a non-linear (hypertext) information structure. This non-linear structure allows users to retrieve information at many different levels but also increases the difficulty of information retrieval. Unlike a well-developed CD-ROM database, the WWW does not have a controlled searching environment and information can be indexed in many different ways. It takes a well planned search strategy to perform an effective search in the labyrinth of the WWW. The SIRO (Systematic Information Retrieval/Organization) model offers a research planning process designed specifically for information seekers in the agricultural disciplines. The intention is to enhance search results and organize retrieved information. This process starts with the identification of the information structure on the WWW, then proceeds by organizing and analyzing information in a visual diagram or a “thinking map.” This process leads searchers to logical sources on the WWW and a systematic analysis of the result. 相似文献

The management of occupational health and safety (OHS) including safety culture interventions is comprised of complex problems that are often hard to scope and define. Due to the dynamic nature and complexity of OHS management, the concept of system dynamics (SD) is used to analyze accident prevention. In this paper, a system dynamics group model building (GMB) approach is used to create a causal loop diagram of the underlying factors influencing the OHS performance of a major drilling and mining contractor in Australia. While the organization has invested considerable resources into OHS their disabling injury frequency rate (DIFR) has not been decreasing. With this in mind, rich individualistic knowledge about the dynamics influencing the DIFR was acquired from experienced employees with operations, health and safety and training background using a GMB workshop. Findings derived from the workshop were used to develop a series of causal loop diagrams that includes a wide range of dynamics that can assist in better understanding the causal influences OHS performance. The causal loop diagram provides a tool for organizations to hypothesize the dynamics influencing effectiveness of OHS management, particularly the impact on DIFR. In addition the paper demonstrates that the SD GMB approach has significant potential in understanding and improving OHS management. 相似文献

The aim of this article was to characterise and compare the level of environmental intelligence among university students from selected countries of Central and Eastern Europe. This was done using empirical data collected by the author in 2015. In the introduction and theoretical part of this text, the term ‘environmental intelligence’ is defined, and issues raised by modern sociologists such as M. Maffesoli and M. Archer are presented. Two hypotheses stating that respondents from Poland, Slovakia and Czech Republic have higher levels of environmental intelligence than university students from the Ukraine, and those studying natural sciences have higher levels of environmental intelligence than students of the humanities or social sciences were verified. The statistical analysis conducted in the second part of the text revealed a higher level of environmental intelligence among students from the European Union countries compared to respondents from the Ukraine. However, there were no significant differences between the level of environmental intelligence and respondents’ faculty of studies. This indicates that studying natural sciences did not contribute to a more dynamic development of environmental intelligence in students. This revelation may be disturbing, as the state of the environment cannot improve if young people cannot use and care for it responsibly. 相似文献

针对环保科技城规划中普遍存在的规划战略理念与实施操作脱节的情况,研究首先论述了规划中战略理念的"远瞻"和实施操作的"近交"两大层面对江苏盐城环保科技城规划的影响,以及二者在产业体系、空间布局和分期扩展等方面的呼应及链接,从而提出只有通过对"远瞻"定位与"近交"策略进行链接式思考,才能保证规划得以有效的贯彻与实施,才能更好地推动环保科技城的发展。 相似文献
