Chaos theory, informational needs, and natural disasters   总被引:2,自引:0,他引:2  
This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning.  相似文献

Purpose: This paper reports the results of survey research conducted with tribal producers between 2011 and 2012 on 19 of the largest American Indian reservations in Idaho, Nevada, North Dakota, Oregon, South Dakota, and Washington. The purpose of the research was to identify potential barriers to sustainable agriculture on reservation lands. This article reports the results of this research in an effort to promote Extension professionals' understanding of these barriers, which may help to improve outreach programs on American Indian reservations. Understanding the obstacles to sustaining agriculture that American Indian tribes face may inform international agricultural outreach efforts to increase food security targeting indigenous and tribal peoples worldwide.

Design/Methodology/Approach: American Indian agricultural producers comprised the study group. Study objectives included: (1) identify agricultural and natural resource issues of greatest concern to a self-selected sample of tribal agricultural producers on reservation lands; (2) evaluate access to Extension and other US Department of Agriculture outreach and assistance programs; and (3) evaluate the quality of these programs in terms of their relativity to tribal needs.

Findings: Study results indicate that tribal agricultural producers surveyed ranked 29 of 39 agricultural and natural resource issues as a concern. Similarly, they rated access to and quality of outreach programs as fair. Further, tribal producers operating on reservation trust land rated issues more severely than did tribal producers operating on fee simple lands.

Practical Implications: Results of this research will help Extension and other outreach professionals to understand the barriers indigenous and tribal peoples face in sustaining agricultural operations, particularly tribal groups living on federally reserved trust lands, such as American Indians. An increased understanding can inform agricultural policy-makers and outreach professionals in improving programs designed to increase agricultural sustainability, improve food security, enhance economic well-being and improve quality of life of indigenous and tribal peoples worldwide.

Originality/Value: This research provides important information to agricultural policy-makers and Extension professionals striving to sustain agricultural productivity and enhance food security with indigenous and tribal peoples.  相似文献

作为教育家的陈独秀,其职业教育思想独具特色。他认为在社会形态中教育属于上层建筑,中国从来就不大重视职业教育,而欧美各国都注重职业教育。主张“一切教育都建设在社会的需要上面”,讲究“实际应用”,强调理论要联系实际,学习要学以致用,希望教育是平民的而非贵族的。陈独秀的职业教育思想在当今仍有现实意义。  相似文献

This paper considers the role of the Special Educational Needs Coordinator (SENCO), the teacher responsible for the implementation of policies relating to the teaching and learning of children with special educational needs (SEN) in mainstream schools in England and Wales. SENCOs also have a role to play in the inclusion of children with learning difficulties/disabilities in mainstream schools. Yet research indicates that despite the revision of the Special Educational Needs Code of Practice in 2001, many SENCOs are still overwhelmed by the operational nature of the role with little support, time or funding to consider more strategic aspects of inclusion and SEN. The article draws on research by the author and offers the voices of SENCOs from two unitary authorities in the north of England which suggest that where the SENCO is supported by senior management within the school, the role can be a powerful one in relation to inclusion. It concludes by arguing that the role of the SENCO needs to be re‐conceptualized, redefined and remunerated as a senior management post within mainstream schools. If this were to be enforced by national policy, every mainstream school could have at least one powerful advocate for the inclusion of children with learning difficulties/disabilities.  相似文献
