The linked dependence assumption, a widely used simpli cation in probabilistic retrieval, is brie y reviewed and its validity is investigated. We show that the linked dependence assumption is violated particularly if the query features are good discriminators between relevant and non-relevant documents. We then propose the manual concept generation method, which takes into account the dependenc...

This paper proposes the paradigm and the corresponding normalization algorithms with coexistence of eXtensible Markup Language (XML) functional dependence and XML values dependence. The concepts of redundancy and keys are firstly described in this paper, while the paradigm with coexistence of XML functional dependence and XML values dependence is defined later. Then, the non-redundancy judgment...

conclusions the results of this study in terms of personality disorders and types of used drugs were in accordance with the previous studies results. it is necessary to design appropriate treatment plans for medical treatment of those with personality disorders. results there was a significant correlation between stimulant use and histrionic personality disorder (p < 0.001) and antisocial and n...

Vygotsky posed a variety of meaningful ideas for education in his short life. This paper focuses on everyday concepts and mathematical concepts or scientific concepts from his theory, reorganizing these ideas according to a new idea of sublated concepts. Using a series of interviews from a third grade fraction class in Japan, the paper discusses how everyday and mathematical concepts arise out ...

This mixed-methods study investigates the effects of student attitudes and behaviours on the outcomes of learning mathematics with computer tools. A computer tool was used to help students develop the mathematical concept of function. In the whole sample (N = 521), student attitudes could account for a 3.4 point difference in test scores between individuals on a 10-point scale. General attitude...

In this paper, we define a binary relation for general collective choice situations, the needing relation, that captures one notion of dependence between alternatives with respect to inclusion in several popular solution concepts, including the top-cycle set, the uncovered set, the Banks set, and the minimal covering set. After defining the relation and relating it to a graph theoretical view o...

Little consensus exists on the risk of benzodiazepine (BZD) dependence. We investigated how often BZD dependence and related concepts have been defined in the literature on BZD effects in humans. In addition, the definitions of BZD dependence were compared in order to assess the similarity of contents. From a total of 250 papers (published between 1988 and 1991) 51 provided 126 dependence-relat...

When there are many people who don't need to expect something more than the benefits to take, we will suggest you to have willing to reach all benefits. Be sure and surely do to take this intelligent open learning systems concepts models and algorithms 1st edition that gives the best reasons to read. When you really need to get the reason why, this intelligent open learning systems concepts mod...

We have come a long way and finally are about to study calculus. Many of you might have taken some courses in the past where you learned a number of formulas to calculate the derivatives and integrals of certain functions. The purpose of this course, however, is not to memorize these formulas mindlessly. Rather, our goals are to understand the mathematical concepts underlying such formulas and ...
