Cherice Joyann Estes The Western Media and the Portrayal of the Rwandan Genocide BY CHERICE JOYANN ESTES ABSTRACT: On December 9, 1948, the United Nations established its Convention on the Prevention and Punishment of the Crime of Genocide. Genocides, however, have continued to occur, affecting millions of people around the globe. The 1994 genocide in Rwanda resulted in an estimated 800,000 deaths. Global leaders were well aware of the atrocities, but failed to intervene. At the same time, the Western media's reports on Rwanda tended to understate the magnitude of the crisis. This paper explores the Western media's failure to accurately interpret and describe the Rwandan Genocide. Recognizing the outside media’s role in mischaracterizations of the Rwanda situation is particularly useful when attempting to understand why western governments were ineffective in their response to the atrocity. -

It would not have been possible without the generous assistance of the libraries and archives I visited, in both the United States and the United Kingdom. However, without the support of the history department and Florida State University, I would not have been able to complete the project. My advisor, Charles Upchurch encouraged me to broaden my understanding of the British Empire, which led to my decision to study Charles Gordon. Dr. Upchurch‘s constant urging for me to push my writing and theoretical understanding of imperialism further, led to a much stronger dissertation than I could have ever produced on my own. -

It has also been included into international end web products [16]. SPEKE has also been included into standards such as ISO/IEC 11770-4 and IEEE P1363.2. In the international standards such as IEEE P1363.2 [22] and this paper, we analyse the SPEKE protocol as specified in the ISO/IEC 11770-4 [24]. ISO/IEC and IEEE standards.

Education in Uganda
0E-14103 Bulletin 1964, No. 32 Education in Uganda by DAVID SCANLON Professor of International Education Teachers College, Columbia University In U.S.DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Office of Education Foreword ASTRIKINGrTHENOMENON of the last few years has been the mounting interest among citizens of the United States in the developing areas of the worldparticularly per- haps the area of middle Africa.Since 1960 most of the coun- tries in this area have gained their independence and are confronting the great problems of nation building and economic development. The entireregionshowsbotha popular enthusiasm for education and a conviction among leaders that education is a key to economic and social developmentan enthusiasm and conviction almost unsurpassed anywhere else in the world. It is not, surprising, then, that during recent years an increas- ing number of Africans have come to study in the United States and hundreds of Americans have traveled in the opposite direc- tion to teach in African schools or otherwise help develop Afri- can educational systems.Administrators of American insti- tutions having African students, teachers of comparative education and social studies, persons engaged in programs for educational assistance in Africa, and others, have reflected a demand for basic information on the educational systems of that continent.This bulletin on education in Uganda is one response to the need. The author, Professor of International Education at Teachers College, Columbia University, spent several months in Uganda during academic year 1960-61 lecturing at the Institute of Edu- cation, Makerere College.During this period he consulted with educators, visited educational institutions, and gathered materials for the present study. -

Thirty-nine out of 150 papers were accepted, and there were two invited talks along with the traditional rump session. About 480 participants from 39 countries were present.

The algorithm has four steps: polynomial selection, sieving, linear algebra, and square root extraction. For N known to be composite, two irreducible polynomials with a common root mod N are needed. f1 (of degree 5 in this case) should have many roots modulo small primes as well as being as small as possible. -

Strong Password-Only Authenticated Key Exchange *
Strong Password-Only Authenticated Key Exchange * David P. Jablon Integrity Sciences, Inc. Westboro, MA [email protected] September 25, 1996 A new simple password exponential key exchange method (SPEKE) is described. It belongs to an exclusive class of methods which provide authentication and key establishment over an insecure channel using only a small password, without risk of offline dictionary attack. SPEKE and the closely-related Diffie-Hellman Encrypted Key Exchange (DH- EKE) are examined in light of both known and new attacks, along with sufficient preventive constraints. Although SPEKE and DH-EKE are similar, the constraints are different. The class of strong password-only methods is compared to other authentication schemes. Benefits, limitations, and tradeoffs between efficiency and security are discussed. These methods are important for several uses, including replacement of obsolete systems, and building hybrid two-factor systems where independent password-only and key-based methods can survive a single event of either key theft or password compromise. 1 Introduction It seems paradoxical that small passwords are important for strong authentication. Clearly, cryptographically large passwords would be better, if only ordinary people could remember them. Password verification over an insecure network has been a particularly tough problem, in light of the ever-present threat of dictionary attack. Password problems have been around so long that many have assumed that strong remote authentication using only a small password is impossible. In fact, it can be done. Since the early 1990’s, an increased focus on the problem has yielded a few novel solutions, specially designed to resist to dictionary attack. -
J-PAKE: Authenticated Key Exchange Without
J-PAKE: Authenticated Key Exchange Without PKI Feng Hao1 and Peter Ryan2 1 Thales E-Security, Cambridge, UK 2 Faculty Of Science, University of Luxembourg Abstract. Password Authenticated Key Exchange (PAKE) is one of the important topics in cryptography. It aims to address a practical security problem: how to establish secure communication between two parties solely based on a shared password without requiring a Public Key In- frastructure (PKI). After more than a decade of extensive research in this ¯eld, there have been several PAKE protocols available. The EKE and SPEKE schemes are perhaps the two most notable examples. Both tech- niques are however patented. In this paper, we review these techniques in detail and summarize various theoretical and practical weaknesses. In addition, we present a new PAKE solution called J-PAKE. Our strategy is to depend on well-established primitives such as the Zero-Knowledge Proof (ZKP). So far, almost all of the past solutions have avoided using ZKP for the concern on e±ciency. We demonstrate how to e®ectively integrate the ZKP into the protocol design and meanwhile achieve good e±ciency. Our protocol has comparable computational e±ciency to the EKE and SPEKE schemes with clear advantages on security. Keywords: Password-Authenticated Key Exchange, EKE, SPEKE, key agree- ment 1 Introduction Nowadays, the use of passwords is ubiquitous. From on-line banking to accessing personal emails, the username/password paradigm is by far the most commonly used authentication mechanism. Alternative authentication factors, including tokens and biometrics, require additional hardware, which is often considered too expensive for an application. -
The Six Lives of Alexine Tinne: Gender Shifts

Many thanks to the UTA History department and College of Liberal Arts for granting the funding necessary for me to visit overseas archives and for fellowships to allow me to complete my writing. To my committee, I thank you for taking the time and the effort to help me shape my arguments, to discuss with me things that I just needed to verbalize before I could get them on paper, and for putting up with all the errant comma placement. Imre Demhardt, thank you for introducing me to cartography and to Alexine Tinne. I had no idea she would take me so far. Stephanie Cole, thank you for guiding me and helping me shape this work into a cohesive look at the gender shifts taking place in the nineteenth century. Your help was invaluable to me! Thank you to my #accountabilibuddies Karen and Kristen who kept me motivated to write even when I really did not want to and saved my sanity when I thought none was left. Thank you Robin for being a stern and strong supporter and to Jeanne for letting me vent my frustrations and always cheering me on.
