Over the past few years the question of whether the lecture is an effective teaching method has been one of the most heatedly debated topics in the field of higher education. While research on the effectiveness of lectures has been carried out since at least the 1960s, the value of the lecture has been increasingly questioned recently for a number of reasons that include waning lecture attendan...

Range-space methods for convex quadratic programming improve in efficiency as the number of constraints active at the solution decreases. In this paper we describe a range-space method based upon updating a weighted Gram-Schmidt factorization of the constraints in the active set. The updating methods described are applicable to both primal and dual quadratic programming algorithms that use an a...

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the effectiveness and safety of yoga for treatment of urinary incontinence in women, compared to no specific treatment, to another active treatment, or to an active treatment without adjuvant yoga, with a focus on patient symptoms and quality of life.

OBJECTIVE A double-blind, placebo-controlled study was performed with 37 patients to assess the efficacy as well as the safety of short-term pre-seasonal subcutaneous immunotherapy (SCIT) with a six-grass pollen allergoid for one year. RESULTS After one pre-seasonal treatment cycle there are significant differences between the groups in favour of active treatment. On a "1-10" visual rating sc...

Remote measurements of trace constituents using an active technique such as lidar have been made possible for the rapid development of powerful tunable laser sources. This paper, originally presented at the OSA Topical Meeting on Optical Remote Sensing of the Atmosphere, in January 1985, illustrates the differential absorption lidar technique used for the measurement of the ozone vertical distr...

In this review talk I discuss the important issues of AGN research and how the new generation of X-ray observatories can help to constrain the physics of AGN. I also present a biased list of the new XMM-Newton and Chandra discoveries and how they have altered our view of AGN. I also present a set of what are the new types of observations that need to be performed to make significant progress in...

It has been recently claimed that the most-obtuse-angle pivot rule is one of the best choices for Phase I linear programs based on the simplex method. In this short note we give two instances of Phase I cycling under such ratio-test-free rule, both when it is used to obtain primal feasibility and when trying to achieve dual feasibility with its unnormalized counterpart. A crash procedure that i...

An experiment is carried out on a subset of a first year group in Semester 1, 2001 for five separate fiftyminute sessions. Five groups are taught using one teaching technique based around the idea of passive learning. Five further groups are taught using a second technique based on active learning within small groups. The remaining three groups face a third approach based on a combination of th...

The primary role of the vocational agriculture teacher has always been to help students learn knowledge and skills in agriculture. In order for the program to justify the time and money utilized on it, it is important that students be taught by competent teachers using a variety of teaching methods and using them appropriately (The Unfinished Agenda. 1986). A competent teacher is the essential ...
