417 College & Research Libraries receives a large number of manuscripts each year that have kept the two of us busy, as editorial assistants, with many of the initial reviews of submission for the journal during the last two years. In 2011 alone C&RL received 134 submissions, of which only 46 were finally selected for publication. This acceptance rate demonstrates the rigor of our review proces...

This paper is concerned with the problem of selfcalibration. First some general concepts are discussed, then several methods are briefly discussed. In the second part of the paper the problem of critical motion sequences is treated. This problem could cause an important limitation to the practical use of self-calibration. In this context several interesting results are presented. self-calibrati...

We question the use of mechanical models, such as coin flipping, to represent the probabilities of gender distributions in sibship families consisting of two children. Both the assumptions of the models and the reliability of the data should be evaluated. Using models without these critical evaluations may tend to perpetuate myths rather than elucidate biological realities.

Many people reason poorly, by almost any measure of reasoning. Although there is evidence that people can be taught to think critically, educators don’t really know how. They don’t know what works, what doesn’t, or why. This report describes the Monash Critical Thinking Study – a three year project to investigate the effectiveness of a number of teaching methods for improving critical thinking....

During modern era of critical phenomena, several inequalities between critical exponents have been derived. However most of these inequalities depend on some assumptions. Beside this, some of these inequalities can be replaced by equalities. Several solved classical models as well as some recent theories have helped us to check the validity of these inequalities. To check these inequalities in ...

In this paper we propose a dialogue game for agents to deliberate over a proposed action. The agents’ dialogue moves are defined by a structured set of argument schemes and critical questions (CQs). Thus, a dialogue move is an instantiated scheme (i.e. an argument) or a CQ (i.e. a challenge on the argument instantiated in the scheme). The proposed dialogue game formalises the protocol based exc...

long-throated flumes are measurement structures often used in water and wastewater systems to determine the flow discharge. the head-discharge relationship of long-throated flumes is traditionally determined following the critical flow theory and the boundary layer concept. after a review of the traditional approach and an analysis of the approximate assumptions of the boundary layer approach, ...

—Having worked for a long time with video-lectures, we devised a new teaching model that makes use of the recorded videos to free the teacher from part of his work and allowing him to concentrate his efforts on a more effective and involving teaching strategy. I. INTRODUCTION Video lectures are becoming more and more popular, especially since important educational institutions such as Princeton...
