Reducing Uncertainty In Sea-Level Rise Prediction: A Spatial-Variability-Aware Approach, Subhankar Ghosh, Shuai An, Arun Sharma, Jayant Gupta, Shashi Shekhar, Aneesh Subramanian Oct 2023

Reducing Uncertainty In Sea-Level Rise Prediction: A Spatial-Variability-Aware Approach, Subhankar Ghosh, Shuai An, Arun Sharma, Jayant Gupta, Shashi Shekhar, Aneesh Subramanian

I-GUIDE Forum

Given multi-model ensemble climate projections, the goal is to accurately and reliably predict future sea-level rise while lowering the uncertainty. This problem is important because sea-level rise affects millions of people in coastal communities and beyond due to climate change's impacts on polar ice sheets and the ocean. This problem is challenging due to spatial variability and unknowns such as possible tipping points (e.g., collapse of Greenland or West Antarctic ice-shelf), climate feedback loops (e.g., clouds, permafrost thawing), future policy decisions, and human actions. Most existing climate modeling approaches use the same set of weights globally, during either regression or …


Sloan On Geopolitics, Geography, And Strategy History In Geopolitics, Bert Chapman Jun 2017

Sloan On Geopolitics, Geography, And Strategy History In Geopolitics, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

Geopolitical literature is experiencing a renaissance and scholars representing classical and critical perspectives in this field bring multifaceted assessments to historical and current international political and security issues. Sloan’s Geopolitics, Geography and Strategic History, which is part of Routledge’s Geopolitical Theory Series, examines connections between geography, strategy, and history and is the subject of this review and analysis. Three thesis questions examined by the author include why the geographical scope of political objectives and following strategies of nation states change, how do these changes occur, and over what time period do these changes occur. Sloan examines why the geopolitical theories …


A Contemporary Citation Analysis Of Geography Education Journals: 2009–2015, Thom Gerrish, Donald Patrick Albert Jan 2017

A Contemporary Citation Analysis Of Geography Education Journals: 2009–2015, Thom Gerrish, Donald Patrick Albert

Libraries Faculty and Staff Scholarship and Research

This study examined the flow of citations from 713 documents emanating from ten geography education journals from 2009 to 2011. The citations generated from these articles were tracked within and between this set of journals from 2009 through 2015. Our searches found 1,067 citations, or an average of 1.5 citations per article. After excluding self-citations, the remaining citations (33.6 percent) filtered out into other geography education journals and were classified into three groups: splash, wave, and ripple. Although the Journal of Geography in Higher Education generated the largest in-degree count, it shared the lead with the International Research in Geographical …


"Chinese Military Space Power: U.S. Department Of Defense Annual Reports, Bert Chapman Mar 2016

"Chinese Military Space Power: U.S. Department Of Defense Annual Reports, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

Following instructions received from the U.S. Congress in the 2000 National Defense Authorization Act, the Department of Defense prepared an annual report on Chinese military power. This report contains classified and unclassif ied editions. Documenting Chinese military space power developments was one of the provisions in this law’s authorizing language. This article will examine how Chinese military space power documents have been described by the Department of Defense during this report's existence through 2015 and detail how members of Congress and Congressional committee hearing witnesses reacted to these developments in Congressional hearing transcripts and in Congressional debate through Fall 2015.


China's Nine-Dashed Map: Maritime Source Of Geopolitical Tension, Bert Chapman Oct 2014

China's Nine-Dashed Map: Maritime Source Of Geopolitical Tension, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

The South China Sea (SCS) is becoming an increasingly contentious source of geopolitical tension due to its significance as an international trade route, possessor of potentially significant oil and natural gas resources, China’s increasing diplomatic and military assertiveness, and the U.S.’ recent and ongoing Pacific Pivot strategy. Countries as varied as China, Taiwan, the Philippines, Indonesia and other adjacent countries have claims on this region’s islands and natural resources. China has been particularly assertive in asserting its SCS claims by creating a nine-dash line map claiming to give it de facto maritime control over this entire region without regard to …
