In this paper, we propose a new bulk-loading technique for high-dimensional indexes which represent an important component of multimedia database systems. Since it is very inefficient to construct an index for a large amount of data by dynamic insertion of single objects, there is an increasing interest in bulk-loading techniques. In contrast to previous approaches, our technique exploits a pri...

The study sought to explain remedial learners’ attitude towards English language using three variables: gender, age and locus of control. Three properly validated instruments were used to collect data on the relevant variables from 385 remedial English learners randomly selected from 5 remedial education centers in Ibadan, Nigeria. Data analysis involved the use of multiple regression to explai...

Is public opinion a beloved but unreal myth like the unicorn? Or a thing out there in the garden like an elephant, of which sight-impaired, competing methodologists measure different parts? Or a fuzzy set of probabilities like the electron, both wave and particle, perhaps of inherently uncertain location? Or does it include all of the above? ...If we want to measure public opinion, we need to d...

In many real-world probabilistic reasoning problems, one of the questions we want to answer is: how many objects are out there? Examples of such problems range from multitarget tracking to extracting information from text documents. However, most probabilistic modeling formalisms — even firstorder ones — assume a fixed, known set of objects. We introduce a language called Blog for specifying pr...

In the current academic climate, there is no shortage of discourses proclaiming a veritable neurorevolution: that new insights into the functioning of the human brain will lead not only to novel possibilities of technoscientific intervention, but also to a radical transformation of our sense of what it is to be human in general. More striking still is the enthusiastic appropriation of this new ...
