This paper presents results of an ongoing research effort to support effective user involvement during modeling and analysis meetings. Productivity and user participation of traditional group meetings have been limitations imposed by chauffeured facilitation and single-user tools. These tools have been designed for analysts rather than for direct use by non-analyst users. Recently, electronic meeting systems (EMS) modeling tools that allow users to work in parallel to contribute directly during meetings have been developed. Such tools allow more domain experts to participate directly and productively during model development meetings than is possible using the traditional approach. Although previous research has demonstrated that EMS modeling tools may be used to develop some model content, little research had been done on collaborative facilitation methods that employ these tools. This paper presents a comparison of modeling approaches for use with EMS modeling tools and proposes an approach that overcomes significant problems inherent in other approaches. It leverages the productivity enhancement afforded by direct group access and still results in production of complete, integrated, high quality models. This approach allows models to be developed two to four times faster than with traditional modeling support and yet avoids model ambiguities and inconsistencies. 相似文献

Since the advent of public and private initiatives in Colombia, there has been interest in exploring the possible future pathways of the Colombian business cycle. Based on a foresight analysis, it has been identified on the one hand that it is necessary to achieve greater productivity and competitiveness and on the other hand, collective intentionality towards progress must be encouraged. Using these analyses, new Colombian scenarios are discussed, taking into account intentionality towards entrepreneurship and innovation. Following the entrepreneurship research, it is suggested that innovative entrepreneurial activity is linked to long-term economic growth. Thus, the purpose of this paper is to identify the role of innovative entrepreneurship in Colombian business cycle scenarios using system dynamics (SD) modelling. Here, we approach futures studies, testing dynamic hypotheses concerning development based on societal and socioeconomic integration, in which innovative entrepreneurship is highly relevant. The model, supported by circular flow analysis and Schumpeterian theory, shows how this type of entrepreneurship contributes to sustainable economic growth during the simulation period (2003–2032). To achieve a 6.77% average growth rate (the higher scenario), policies regarding knowledge transfer from specialized foreign individuals, incumbent firms and universities, as well as incentives for entrepreneurial societies and collectivism, are discussed. 相似文献

Enhancing ecosystem services in vineyards: using cover crops to decrease botrytis bunch rot severity
Botrytis bunch rot is a disease that causes loss of yield and quality in many fruit and vegetable crops in temperate climates worldwide. The rot is caused by the fungus Botrytis cinerea, a saprophytic necrotroph. In grapes, the presence of the fungus can reduce yield, taint wine and increase its sensitivity to oxidation. In the current work, inter-row phacelia and ryegrass were mulched in situ in winter 2005 and compared with a bare ground control. The mulches were applied under 10-year-old Chardonnay vines in a 10-replicate randomized block design in New Zealand. Functional soil biological activity increased by 1.5–4.5 times in the two cover crop treatments compared with the control, an effect related to elevated soil moisture in these treatments. This increase in soil moisture and a higher rate of soil biological activity increased vine debris degradation, reduced B. cinerea primary inoculum on the debris and decreased B. cinerea severity at flowering (December 2005) and harvest (April 2006). These results show the potential of mulched cover crops to enhance soil ecosystem services, reduce variable costs and improve the sustainability of viticulture and potentially other agricultural systems, in temperate climates worldwide. 相似文献

A two-dimensional model on escape motives in activity engagement was developed in three studies. We suggested that motivation to escape the self through engagement in an activity partly derives from intentions to either prevent negative affect or to promote positive affect. A scale for measuring these intentional mindsets was developed consisting of the subcategories self-suppression and self-expansion. Results showed that the dimensions were differently related to psychological predictors, outcomes, and experiences in the activity engagement. We argue that the present research introduces escapism as a relevant theoretical and empirical concept applicable to several types of activity engagements. 相似文献

社会融入是社会行动的结果,而经济活动是社会行动的首要活动。根据对陕西省西安市的调查数据,以“是否持续参与城市社会经济活动”考量“村改居”群体的城市社会融入与否,运用二元Logistic回归模型,从自身特征、经济资本、人力资本和社会支持4个方面分析“村改居”群体城市社会融入的影响因素,结果表明:“村改居”群体的城市社会融入与年龄、性别等自身条件无关,经济资本中分红、房租等可替代收入变量和人力资本中高层次职业变量的影响不显著,社会支持等外部因素的影响也不显著;交往能力和政策制度变量在各自的类别模型中对“村改居”群体的城市社会融入具有显著影响,但未能进入最终模型;就业收入、文化程度和一技之长对“村改居”群体的城市社会融入具有显著正向。因此,“村改居”群体提高就业收入和文化程度以及拥有一技之长,均有助于其城市社会融入进程。 相似文献
