Can intermunicipal collaboration help the diffusion of E-Government in peripheral areas? Evidence from Italy     

Enrico Ferro  Maddalena Sorrentino 《Government Information Quarterly》2010

This paper analyzes the implementation of new intermunicipal structures in Italy to support the development of E-Government in the country's peripheral areas. Our exploratory case study, conducted in the Piedmont Region, shows that intermunicipal collaborations can facilitate the coordination of interdependent subjects, rationalize existing resources (e.g., through the reuse of application software solutions), and prevent the dispersion of federal government funds. Nevertheless, intermunicipal collaborations alone do not seem to have the power needed to ensure that decisions made at the central level will automatically translate into concrete and binding commitments for the municipalities involved. From a methodological standpoint, the article makes use of the analytical frameworks offered by organization science to interpret the effects of collaborative arrangements on E-Government implementation.  相似文献   

Strengthening Agricultural Education and Training in sub-Saharan Africa from an Innovation Systems Perspective: A Case Study of Mozambique     

Kristin E. Davis  Javier Ekboir  David J. Spielman 《The Journal of Agricultural Education and Extension》2013,19(1):35-51

Abstract

This paper examines how post-secondary agricultural education and training (AET) in sub-Saharan Africa can contribute to agricultural development by strengthening the capacity to innovate—to introduce new products and processes that are socially or economically relevant to smallholder farmers and other agents. Using the AET system in Mozambique as a case study, this paper examines the role of AET within the context of an agricultural innovation system. This innovation systems perspective offers an analytical framework to examine technological change in agriculture as a complex process of interactions among diverse actors who generate, exchange, and use knowledge, conditioned by complex social and economic institutions. The paper argues that while AET is conventionally viewed as key to the development of human capital, it also has a vital role to play in building the capacity of organizations and individuals to transmit and adapt information, products and processes, and new organizational cultures and behaviors. The paper emphasizes the importance of improving AET systems by strengthening the capabilities of organizations and professionals; changing organizational cultures, behaviors, and incentives; and building innovation networks and linkages. The paper offers several recommendations to enhance the effectiveness of AET for agricultural innovation and development. Key reforms include aligning the mandates of AET organizations with national development aspirations; inducing change in the cultures of AET organizations through the introduction of educational programs and linkages beyond the AET system; and enhancing innovative individual and organizational capacity by improving incentives to forge stronger links between AET and other stakeholders.  相似文献   

Cognitive load and knowledge sharing in Learning Networks     

Ya P. Hsiao  Francis Brouns  Liesbeth Kester  Peter Sloep 《Interactive Learning Environments》2013,21(1):89-100

Learning Networks (LNs) are online social networks designed to support nonformal learning; they are therefore particularly suitable for self-directed learners. In LNs, learners need to construct knowledge through knowledge sharing with other participants. However, without support, learners have to organize knowledge sharing themselves and this could induce extraneous cognitive load. When working on complex learning tasks, this organizing process could have a detrimental effect on knowledge construction. To optimize cognitive load, we propose using a peer support system that applies the mechanisms of peer tutoring to support knowledge sharing. Its mechanisms reduce, we argue, the extraneous load imposed by having to organize knowledge sharing as well as induce germane load by directing the freed-up cognitive capacity to processes that contribute to knowledge construction.  相似文献   

When Transnational Civil Network Meets Local Context: An Exploratory Hyperlink Network Analysis of Northern/Southern NGOs' Virtual Network in China     

《Journal of International and Intercultural Communication》2013,6(1):40-60

Abstract

Nongovernmental organizations (NGOs) are important communicators in the international arena, but few studies have explored the encounter between Northern NGOs (NNGOs) and Southern NGOs. This study examines how NNGOs build relationships with Chinese NGOs (CNGOs) online and how network positions affect the amount of local media coverage NNGOs receive. This study revealed three major findings: NNGOs occupied a disadvantageous network position; a close connection with CNGOs was crucial for NNGOs to attract media coverage; and NNGOs' and CNGOs' virtual networks demonstrated structural patterns similar to those of their offline networks. This study calls for attention to a mutually beneficial virtual communication structure.  相似文献   

Explaining the persistence of “decentralisation” of education in Egypt     

《International Journal of Educational Development》2021

This study examines how and why decentralisation remained central to education reform in Egypt over the period 1990–2016 despite the mixed outcome at both the national and international levels. Three decentralisation models were examined: community schools, public-private partnerships and school-based management. Network analysis was combined with a process-tracing approach to identify the key actors and mechanisms causing policy persistence. Analysis revealed international agencies used coercion through funding and persuasion by framing the models to match political sponsors’ interests. There was also bounded-rational learning by national actors from foreign experts and experiences and several complementary mechanisms with minor influence.  相似文献   

基于Google Earth的车辆防碰撞虚拟仿真系统     

肖广兵  陈有超  季淦  孙宁  陈勇 《教育技术导刊》2019,18(10):107-110

车载自组织网络（VANET）是近年来智能交通领域的研究热点之一。在VANET网络中,智能车辆通过交互共享道路环境信息,可提高交通安全水平。在现实环境中进行大规模的车载自组织网络实验,在经济性和可行性上都具有较大困难。在SUMO交通仿真基础上开发出车辆防碰撞虚拟仿真系统,通过Google Street Map获取真实道路环境（如路网、楼宇、植被等）,并结合 GEMV2软件对智能车辆在真实道路环境下的无线通讯链路质量进行评估,实现了虚拟行车交通流与车辆间无线通讯质量评估两位一体的模拟仿真,增强了车辆对周围道路交通环境的综合感知能力。  相似文献
