Abstract:

High embryonic and fetal death rates in manipulated embryos in laboratory suggest that the process of early placentation can be inefficient. This investigation aimed to evaluate the development of placenta, and organogenesis of Nelore bovine embryos, and fetuses by natural stud and in vitro fertilization (IVF) over the period from 15 to 70 days of pregnancy. Fifty-nine embryos (15 to 50 days of gestation), 9 fetuses in initial period (60 to 70 days of gestation), and 10 embryos originated by IVF technique (35 to 46 days of gestation) were used. The same semen was used for all IVF, except the e

Abstract:

AbstractField experiments, in which the researcher manipulates one or more variables in a naturally occurring setting, have sometimes been used in studies of social conflict and should probably be used more often. They are more useful than observational studies for assessing the impact of novel conditions, establishing cause and effect, and reducing confounding. And they are more useful than laboratory experiments for examining long-term effects and those that involve strong passions, and for establishing external validity. However field experiments also have their limitations. Some variables

Abstract:

It is well established that the satiety providing effects of food can influence meal size and a disparate area of research suggests that memory regarding recent eating informs food intake. Here we examined whether remembered meal satisfaction (encompassing memory for meal liking and satiety) can be manipulated in the laboratory and whether this influences later food intake. Participants (N = 128, body mass index mean = 23.46kg/m2, standard deviation = 4.70) consumed a fixed lunch and then rehearsed the satisfying or dissatisfying aspects of the meal, or a neutral experience (control), in order

Abstract:

Abstract Most mobile organisms respond to multiple cues when selecting habitat types, and laboratory experiments that manipulate only single cues may fail to reveal the true complexity of habitat-selection behaviour. In south- eastern Australia, broad headed snakes Hoplocephalus bungaroides (Elapidae) lie in wait under sun-warmed rocks to ambush velvet geckos Oedura leseuerii (Gekkonidae). Previous laboratory work has shown that both the geckos and the snakes actively select hotter rather than colder rocks, and that the snakes actively select rocks scented by geckos. We manipulated rock temper

Abstract:

Animals use cues to find their food, in microhabitats within their physiological tolerances. Termites build and modify their microhabitat, to transform hostile environments into benign ones, which raises questions about the relative importance of cues. Termites are desiccation intolerant and foraging termites are attracted to water, so most research has considered moisture to be a cue. However, termites can also transport water to food, and so moisture may play other roles than previously considered. To examine the role of moisture, we compared Coptotermes acinaciformis termite foraging decisi

Abstract:

This article examines how the presentation of information during a laboratory experiment can alter a study’s findings. We compare four possible ways to present information about hypothetical candidates in a laboratory experiment. First, we manipulate whether subjects experience a low-information or a high-information campaign. Second, we manipulate whether the information is presented statically or dynamically. We find that the design of a study can produce very different conclusions. Using candidate’s gender as our manipulation, we find significant effects on a variety of candidate evaluation

Abstract:

I developed an interactive computer program that allows one to demonstrate and experiment with various phenomena in visual perception using IBM-compatible computers. The program contains modules for demonstrating the color afterimage, the cafe illusion, additive color mixing and the opponent-process theory of color vision, the glowing axes illusion, the Hermann grid, the McCollough effect, the motion aftereffect, the neon illusion, and simultaneous contrast. The user has considerable control over the stimuli making up the image and can manipulate the variables that contribute to the perception

Background: We sought to reduce healthcare-associated infections (HCAIs) through the application of complexity science. Objective: To confirm incidental findings that altering the structure of microbiology reports with targeted education led to better utilisation of laboratory resources, while participating in efforts to reduce HCAI. Methods: We adopted a different approach to laboratory result authorisation, using narrative to engage the clinicians and induce behavioural change. Subsequent educational opportunities emphasised key messages. Findings/Results: Positive urine means calculated by
