Optimizing the Learning Order of Chinese Characters Using a Novel Topological Sort Algorithm

We present a novel algorithm for optimizing the order in which Chinese characters are learned, one that incorporates the benefits of learning them in order of usage frequency and in order of their hierarchal structural relationships. We show that our work outperforms previously published orders and algorithms. Our algorithm is applicable to any scheduling task where nodes have intrinsic differences in importance and must be visited in topological order

Transitive reduction of citation networks

In many complex networks, the vertices are ordered in time, and edges represent causal connections. We propose methods of analysing such directed acyclic graphs taking into account the constraints of causality and highlighting the causal structure. We illustrate our approach using citation networks formed from academic papers, patents and US Supreme Court verdicts. We show how transitive reduction (TR) reveals fundamental differences in the citation practices of different areas, how it highlights particularly interesting work, and how it can correct for the effect that the age of a document has on its citation count. Finally, we transitively reduce null models of citation networks with similar degree distributions and show the difference in degree distributions after TR to illustrate the lack of causal structure in such models

STUDIES OF PERFORMANCE AND PREDICTABILITY OF CACHE-LOCKING

Today’s real-time systems need to be faster and more powerful than ever before. Caches are an architectural feature that helps solve this problem. Caches however are unpredictable and do not improve the worst case execution time. This work studies the effects of cache-locking on performance and time predictability. Two locking methods were evaluated: a dynamic locking method and a static locking method. The performance of single and multi-core processors and multiple levels of caches were studied. The time predictability of the single core system was studied and the cost of the time predictability was determined for each locking method. Cache-locking in the Level 2 cache had the best performance and the static-locking method had the highest predictability

We Can\u27t Fix Their Idiot Lives: Juvenile Treatment Programs in an Era of Neoliberal Social Abandonment

Using two months of interviews and fieldwork at Youth Care Corp., a non-residential treatment program for court mandated youth, this project serves as a case study and critique of theorized structural shifts around and within the crime control apparatuses of the U.S., such as the expanding privatization of welfare, increases in risk management thinking, and the abandonment of the rehabilitative ideal. In this paper I argue that a combination of these forces, in particular the de-funding of welfare services and move away from deviant rehabilitation, has created a tension within Youth Care Corp. between its institutional focus on the responsibilizing empowerment of low-risk youth and the informal, unprofessional provision of welfarist direct aid by individual staff

Shadow of the Patriarch: Amanda Labarca Hubertson\u27s Views on North American/Latin American Relations

Amanda Labarca Hubertson (1886-1975) is recognized as one of Chile\u27s foremost thinkers, educators and feminist leaders of the 20th century. vVhile the genre of travel writing comprises only a small part of Labarca\u27s substantial writing career, the present essay under discussion, From Chile, represents the culmination of observations and reflections on North American and Latin American cultures derived from Labarca\u27s extended visits to the U.S. during the first half of the 20th century. Originally developed as an unpublished essay called Toward a Better Understanding ( Hada un entendimiento mejor ), this essay was included in the collection entitled As Others See Us: The United States Through Foreign Eyes, edited by Franz M. Joseph in 1959. (Paul 2/ 27) Like a number of other publications and activities sponsored by private pro-American foundations in years following World War II, this book containing Labarca\u27s essay was commissioned by an educational organization, the American-European Foundation, ostensibly as a vehicle to promote cultural understanding but also undoubtedly to defend North American culture. (Berghahn 416) For Labarca, however, it represented the opportunity to condense half a century of experiences and reflections into one essay with the goal of promoting hemispheric understanding and mutual respect

Evangelical Perspectives on Latino Immigration

Since 2006, a number of evangelical Christian leaders and organizations have become allies to the movement for comprehensive immigration reform in the United States. Starting with the historical context of the Civil Rights movement, this study will examine points of contact and divergence among the positions and practices of white, black and Latino evangelicals regarding the issue of Latino immigration. Notable nuances within and among the groups exist due to theological traditions, lived experience, socio-economic considerations and demographics. In order to become more effective allies in the comprehensive immigration reform movement, evangelical Christians need to address a number of challenges as individuals, churches, and denominations

Cedarville University: Defining Legacies

Cedarville University’s 125th anniversary in 2012 provided an appropriate moment to look back and remember how God has led so many wonderful people to this place and how His hand has guided and kept us over all these years. As the university continues to grow and change, many individuals new to the campus—students, administrators, faculty and staff members alike—may not be aware of all the contributions of those who preceded them. In order to capture those lives before they are lost to history, Dr. Loach set out to record the stories behind some of the faces and names long associated with the university. In addition, she highlights how some of the university\u27s more than 30,000 alumni have served the Lord through various fields of endeavor around the world.https://digitalcommons.cedarville.edu/cedrus_press_publications/1017/thumbnail.jp
