Recent studies comparing terrestrial versus aquatic locomotion in animals have shown that changes in kinematics, muscular activation patterns, and performance across media are often dramatic. Surprisingly, however, despite the importance of feeding to the survival of most animals, few studies have compared differences in feeding behaviour between media. The present study compares prey-capture b...

Abstract Strikes are a recurrent phenomenon in many countries. However, research on strikes from psychological perspective has been limited. By developing sound measure to assess attitudes and behavioral reactions strikes, we will be better position evaluate these constructs individuals compare across studies. Therefore, developed scale following classic development guidelines using four sample...

BACKGROUND Nigeria has suffered from several healthcare workers' strikes in the past 36 months, involving all categories of health workers. Frequent healthcare workers' strikes result in the closure of public healthcare institutions preventing Nigerians' access to quality health services. The purpose of this study was to identify the root cause(s) of strikes by healthcare workers, their effects...

Death or injury to whales from vessel strike is one of the primary threats to whale populations worldwide. However, quantifying the rate of occurrence of these collisions is difficult because many incidents are not detected (particularly from large vessels) and therefore go unreported. Furthermore, varying reporting biases occur related to species identification, spatial coverage of reports and...

Antipredator responses may appear unsuccessful when animals are exposed to approaching vehicles, often resulting inmortality. Recent studies have addressedwhether certain biological traits are associated with variation in collision risk with cars, but not with higher speed-vehicles like aircraft. Our goal was to establish the association between different species traits (i.e., body mass, eye si...

The Department of the Navyimplemented its present mandatory bird-aircraft strike reporting system in 1981. Reported bird-aircraft strikes have increased each year, presumably due to increased awareness and compliance with regulations. Four Naval air stations implementing birdaircraft strike hazard reduction programs in 1984 reported 57-78% fewer strikes in 1984 than in 1983.

In 1975, writing about the immorality of a strike by resident physicians (housestaff) in New York City,1 I pointed out that "for a physician to strike, for whatever reason, is unconscionable and totally contrary to every standard. of medical ethics and morality." Although sympathetic to the demands of the housestaff, I argued that to leave patients without direct medical assistance and attendan...

New genetic mapping studies explain why a certain mouse strain is predisposed to developing fatal leukemia. Turcotte et al., reporting on page 881, identify a point mutation in the transcription factor IRF-8 (interferon regulatory factor 8) that abolishes its function and sets the stage for a second, leukemia-triggering mutation. The recombinant mouse strain BXH-2 is known to develop first a my...

Electrical burn injuries account for about 5% of burns unit admissions. Electricians and linesmen are at highest risk but those working with electrical tools also form a significant proportion of this patient group. [2] Electrical injuries in children are unusual and are mainly due to misguided exploration outside the home. [3] For every death, there are two serious injuries and 36 reported ele...
