the effects of cooperative versus individual directed reading thinking activities on students inferential and referential questions
two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...
15 صفحه اولBaseline Behavior of Pilot Whales and their Responses to Playback of Anthropogenic and Natural Sounds
This project investigated the social ecology and baseline behavior of long-finned pilot whales as part of a broad multi-investigator research program that seeks to understand how cetaceans are affected by mid-frequency sonar and other sources of anthropogenic noise. The study of how noise affects large delphinids is important since results so far have suggested that they have different response...
متن کاملEnvironmental Influences on Mountain Gorilla Time Budgets
Data on the time budgets of mountain gorillas (Gorilla gorilla beringei) were collected during field studies in the Virunga Volcanoes region of Rwanda and Zaire. Focal sampling was used to determine the proportion of time that individuals of different agehex classes spent in several mutually exclusive activity states. The gorillas spent the majority of daylight hours feeding; most of the rest o...
متن کاملThe Demographic Effects of Increasing Anthropogenic Noise on Mysticeti Whales
Over the past five decades anthropogenic (man-made) noise has increased in the world’s oceans due to an increase in shipping, oil drilling, research activities, and military explorations. All of these factors have contributed to a dramatic elevation of low frequency noise in the oceanic environment. Research on marine mammals has shown that noise below 1000Hz can cause physical trauma to their ...
متن کاملAssessment of Management to Mitigate Anthropogenic Effects on Large Whales
United States and Canadian governments have responded to legal requirements to reduce human-induced whale mortality via vessel strikes and entanglement in fishing gear by implementing a suite of regulatory actions. We analyzed the spatial and temporal patterns of mortality of large whales in the Northwest Atlantic (23.5°N to 48.0°N), 1970 through 2009, in the context of management changes. We u...
