Starting and Sustaining an Undergraduate Research Program: The SURIEM Experience at Michigan State University

Abstract

Mentoring undergraduate students in research is both rewarding and challenging. In this paper we present how we established a summer Research Experience for Undergraduates (REU) program in the mathematical sciences at Michigan State University. A goal of our REU is to include students who are at an early stage of their study of mathematics. We share our experiences in recruiting students, designing research projects, and mentoring our participants. We discuss the challenges we faced and the solutions we found while working with a diverse group of undergraduate students from across the nation.     

对古代文学地域性研究的思考——以荆楚地区的唐诗研究为重点来考察

从地域角度研究中国古代文学,近年来引起人们的关注,关陇、中原、吴越、巴蜀、岭南等地区的古代文学的研究成果日丰。但作为既有悠久传统,又有着典型的地域特色的荆楚地区的文学,从《楚辞》以后便很少有人问津,给人以楚文学从汉末就中流截断之感。其实,由于荆楚地区独特的文化氛围和民族性格,使荆楚文学一直以独特的地域性,流响在华夏文学的水脉里。     

充分发挥“邓小平理论概念”课的思想政治教育作用

“邓小平理论概论”课是高校思想政治工作的重要阵地。当前应以邓小平理论“三进”为核心，加强对大学生的思想政治4教育，这就需要加强师资队伍建设、提高教师素质；努力开辟第二课堂；加强网络战线制控权，保证“思想政治教育”网的“红色”基调。     

Hybrid ants-like search algorithms for P2P media streaming distribution in ad hoc networks

Media streaming delivery in wireless ad hoc networks is challenging due to the stringent resource restrictions,po-tential high loss rate and the decentralized architecture. To support long and high-quality streams,one viable approach is that a media stream is partitioned into segments,and then the segments are replicated in a network and served in a peer-to-peer(P2P) fashion. However,the searching strategy for segments is one key problem with the approach. This paper proposes a hybrid ants-like search algorithm(HASA) for P2P media streaming distribution in ad hoc networks. It takes the advantages of random walks and ants-like algorithms for searching in unstructured P2P networks,such as low transmitting latency,less jitter times,and low unnecessary traffic. We quantify the performance of our scheme in terms of response time,jitter times,and network messages for media streaming distribution. Simulation results showed that it can effectively improve the search efficiency for P2P media streaming distribution in ad hoc networks.
