Charismatic as well as politically astute, Ton Nu Thi Ninh is a patient woman — up to a point. As a high-ranking member of Vietnam's Communist Party, and regarded as the most powerful woman in...
The article discusses how Vietnamese citizens Ton Nu Thi Ninh and Dang Thi Hoang Yen have worked to support the creation of private universities in Vietnam. The author discusses the perception of private education in Vietnam.
The presidents of the nation’s major private research universities were paid a median compensation of $627,750 in the 2007-8 fiscal year — a 5.5 percent increase from the previous year — according to The Chronicle of Higher Education annual executive compensation survey.
The fast-growing group of millionaire private college and university presidents hit a new record in recent years, and it's likely more college leaders will make seven-figure salaries once the slumping economy rebounds.
Während man sich weiter über mögliche Monetarisierungsmodelle für den beliebten Microblogging-Service Twitter Gedanken macht, sind bereits viele kreative Menschen am
With all the skepticism of whether it's just a social media fad and questions about how the company expects to generate revenue, Twitter has left many critics silent by continuing to grow.
The article discusses Covenant University in a town outside Lagos, Nigeria. As a privately run, Christian university, it breaks with a Nigerian tradition of free public higher education. The demand among Nigerian youth for higher education is beyond what the state can provide, leaving an opening for private institutions.
Abstract:
In this paper, an algorithm for cluster generation using tabu search approach with simulated annealing is proposed. The main idea of this algorithm is to use the tabu search approach to generate non-local moves for the clusters and apply the simulated annealing technique to select suitable current best solution so that speed the cluster generation. Experimental results demonstrate the proposed tabu search approach with simulated annealing algorithm for cluster generation is superior to the tabu search approach with Generalised Lloyd algorithm. 1 Clustering Clustering is the process of grouping patterns into a number of clusters, each of which contains the patterns that are similar to each other in some way. The existing clustering algorithms can be simply classied into the following two categories: hierarchical clustering and partitional clustering [1]. The hierarchical clustering operates by partitioning the patterns into successively fewer structures. This method gives rise to a d...
Great branding has always been about influence and not control. Today, the way to achieve this is by observing the conversation and involving yourself in it.
CiteSeerX - Document Details (Isaac Councill, Lee Giles): Clustering is a hard combinatorial problem and is defined as the unsupervised classification of patterns. The formation of clusters is based on the principle of maximizing the similarity between objects of the same cluster while simultaneously minimizing the similarity between objects belonging to distinct clusters. This paper presents a tool for database clustering using a rule-based genetic algorithm (RBCGA). RBCGA evolves individuals consisting of a fixed set of clustering rules, where each rule includes d non-binary intervals, one for each feature. The investigations attempt to alleviate certain drawbacks related to the classical minimization of square-error criterion by suggesting a flexible fitness function which takes into consideration, cluster asymmetry, density, coverage and homogeny.

Wikipedia has rapidly become one of the most used reference sources in the world, but a new study shows that the website's explosive growth is tailing off and also suggests the community-created encyclopaedia has become less welcoming to new contributors.
The article discusses fears among U.S. private colleges and universities that the state aid they receive may be among the first programs cut as states tighten their budgets. Fluctuations in state spending on private higher education are discussed, as are the types of aid, including money given directly to colleges and grants and loans to in-state students.

Armed with a Sh500 million war chest in funds, partly raised through a private placement, the Kenya School of Professional Studies is set to expand its facilities after getting the green light to operate as a private university.
The Federal Government last week announced the granting of licences to enable seven new private universities to operate. With that approval, the number of recognised universities in the country rose to ninety-six, thirty-four of them private.
Immer wieder wird vom "lebenslangen Lernen" gesprochen. Das Bachelor/Master-System unterstützt diese Idee eigentlich – doch in Sachen Finanzierung gibt es noch viele Hürden. Viele Leistungen sind ab 30 nicht mehr (oder nur in Ausnahmefällen) zugänglich oder sie sind teurer als für jüngere Studierende. Oliver und Katrin Iost fassen zusammen, auf was zu achten ist, welche Ausnahmen es gibt und warum sich Betroffene durchaus zusammen tun sollten, um Änderungen zu erreichen.
Die wohl erste Meldung zum Amoklauf in Ansbach kam über den Kurznachrichtendienst Twitter: Ein Student verbreitete die Nachricht, obwohl er selbst nicht am Tatort war.
CiteSeerX - Document Details (Isaac Councill, Lee Giles): Clustering categorical databases presents special difficulties due to the absence of natural dissimilarities between objects. We present a solution that overcomes these difficulties that is based on an information-theoretical definition of dissimilarities between partitions of finite sets (applied to partitions of the set of objects to be clustered which are determined by categorical attributes) and makes use of genetic algorithms for finding an acceptable approximative clustering. We tested our method on databases for which the clustering of the rows is known in advance and we show that our proposed method finds the natural clustering of the data with a good classification rate, better than that of the classical algorithm k-means.
CiteSeerX - Document Details (Isaac Councill, Lee Giles): In a database with categorical attributes each attribute denes a partition whose classes can be regarded as natural clusters of rows. The main theme of this paper is nding a partition of the rows of the database that is as close as possible to the partitions associated to each attribute. The classes of this partition will then be treated as clusters of rows. We evaluate the closeness of two partitions by using certain generalizations of the classical conditional entropy. From this perspective, we wish to construct a partition (referred to as the median partition) such that the sum of the dissimilarities between this partition and all the partitions determined by the attributes of the database is minimal. Then, the problem of nding the median partition is an optimization problem over the space of all partitions of the rows of the database for which we give an approximative solution. To search more eciently the space of possible partitions, which can be very large, we are using a genetic algorithm. Partitions are represented by chromosomes and we tested both the classical techniques of mutation and crossover and certain special mutation and crossover methods that contain specic knowledge of the problem domain. Keywords: median partition, Shannon entropy, Gini index, mutations, crossover operations 1
Screen scraping is the art of programatically extracting data from websites. If you think it's useful: it is. If you think it's difficult: it isn't. And if you think it's easy to really piss off administrators with ill-considered scripts, you're damn right.
