Commercial whaling during the 20th century drastically reduced many populations of great whales in the Southern Hemisphere. The Antarctic blue whale, for example, is estimated to have been reduced to less than 0.1% of its original abundance based on catch records and population dynamic models. Despite this population bottleneck, several...

The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...
Purpose
The purpose of this study was to investigate the effects of a required
mathematics content course upon prospective elementary school
teachers at Brigham Young University. The investigation consisted of
three major areas: (1) attitudes toward mathematics, (2) basic mathematical
understanding, and (3) the relationship between certain selected
variables.
Procedure...
The central purposes of this study were to review the
historical sources of David Kolb's formulation of experiential
learning theory, and to determine the effect and
application of Kolb's theory and Learning Style Inventory
as reflected in the literature between 1971 and 1990.
It was found that Kolb based his...
Several dolphin species have global distributions. The extent of their radiation and limits to gene flow are presumably a product of oceanographic features both recent and historical, behavioral specializations and social organization. Rough-toothed dolphins (Steno bredanensis) are globally distributed in tropical and subtropical waters and are generally found in depths...
The sperm whale (Physeter macrocephalus) shows some of the most derived characteristics of any mammal: a large body size, large brain, complex social organization and a capacity for deep foraging dives that few other marine mammals can match. Despite a history of exploitation that removed hundreds of thousands of individuals,...
This was an experimental study designed to compare the effectiveness
of computer-assisted laboratory instruction to teacher-assisted
laboratory instruction based on student achievement in Elementary
Business Statistics. Computer-assisted laboratory materials and an
Elementary Business Statistics achievement test were evaluated.
Procedures
The setting of this experiment was at Southern Oregon State
College,...
This study was designed with two major aims. The first was toexamine certain characteristics of both Departmental and Non- Departmentalteachers who were teaching matriculation chemistry in SouthAustralian secondary schools during 1967. The numbers of teacherswho participated were: Departmental 40, and Non - Departmental 23.The second was to ascertain certain learning...
