NCBI ROFL: When it comes to walking backward, practice makes perfect.

By ncbi rofl | February 21, 2013 12:00 pm

The effect of repeated bouts of backward walking on physiologic efficiency.

“Previous studies have demonstrated an increased energy expenditure with novel tasks. With practice, the energy cost decreases as the body more efficiently recruits motor units. This study examined whether one becomes more efficient after repeated bouts of backward walking. Read More


NCBI ROFL: Drug use patterns at major rock concert events.

By ncbi rofl | February 5, 2013 3:00 pm

To describe alcohol and drug use patterns in patients presenting to first aid stations at major rock concerts.
We retrospectively reviewed all charts generated at the first aid stations of five major rock concerts featuring the rock groups Pink Floyd, the Grateful Dead, and the Rolling Stones. The first aid stations, located at a sports stadium, were staffed by paramedics, emergency medicine nurses, and physicians. We recorded the following data: patient demographics, history of drug or ethanol use, time spent by patient in first aid station, treatment rendered, diagnosis, and patient disposition. Read More


NCBI ROFL: Groundbreaking study finds beaches more popular on sunny days.

By ncbi rofl | September 3, 2012 7:00 pm

Assessing preferences of beach users for certain aspects of weather and ocean conditions: case studies from Australia.

“Three well-known Australian beaches, Surfers Paradise Beach (Gold Coast), Narrowneck Beach (Gold Coast) and Bondi Beach (Sydney), were selected for analysis of beach user preferences for certain weather and ocean conditions. Regression methods were used to determine how the numbers of visitors to these beaches are affected by these conditions. Actual visitor numbers were counted at three times during the day over several months at each beach with the aid of web cameras. The corresponding weather and ocean conditions were obtained from the Australian Bureau of Meteorology and local government agencies. Weekly and seasonal factors were also considered. Read More

NCBI ROFL: Surprise surprise, sarcasm is hard to communicate via email.

Egocentrism over e-mail: can we communicate as well as we think?

“Without the benefit of paralinguistic cues such as gesture, emphasis, and intonation, it can be difficult to convey emotion and tone over electronic mail (e-mail). Five experiments suggest that this limitation is often underappreciated, such that people tend to believe that they can communicate over e-mail more effectively than they actually can. Read More

NCBI ROFL: Apparently, you can't bribe doctors with candy.

By ncbi rofl | August 2, 2012 7:00 pm

Randomized trial of 5 dollars versus 10 dollars monetary incentives, envelope size, and candy to increase physician response rates to mailed questionnaires.

“BACKGROUND: The validity of the results of mailed surveys is often threatened by nonresponse bias, which is made more likely when response rates are low. However, the effectiveness and cost-effectiveness of several strategies to increase response rates are uncertain. OBJECTIVES: To assess three strategies to increase response rates to mailed physician surveys: including a 10 dollars versus a 5 dollars cash incentive in the initial mailing, including a mint candy or not, and using a large versus small outgoing envelope.

NCBI ROFL: Why watching the Food Network could sabotage your diet.

By ncbi rofl | July 17, 2012 7:00 pm

Watching food-related television increases caloric intake in restrained eaters.

“While watching 30-min television (TV) programs that contained either food-related content or non-food-related content, participants were asked to eat two types of candy by explicitly being told that we were interested in how the TV program influenced their taste and therefore they needed to consume some of those candies.

NCBI ROFL: Do nachos count as a meal? Depends on which college student you ask.

By ncbi rofl | June 13, 2012 7:00 pm

Categorization of foods as “snack” and “meal” by college students.

“The cognitive representation of a food as being a “snack” or a “meal” influences eating behavior. We found previously that subjects who considered a particular food to be a ‘snack’ ate significantly more calories when tested later than subjects who considered the same foods as a ‘meal’. We conducted two surveys to determine the categorization of foods as “snacks” or “meals”. Read More

NCBI ROFL: Nice guys really do finish last.

By ncbi rofl | June 11, 2012 7:00 pm

Do nice guys–and gals–really finish last? The joint effects of sex and agreeableness on income.

“Sex and agreeableness were hypothesized to affect income, such that women and agreeable individuals were hypothesized to earn less than men and less agreeable individuals. Because agreeable men disconfirm (and disagreeable men confirm) conventional gender roles, agreeableness was expected to be more negatively related to income for men (i.e., the pay gap between agreeable men and agreeable women would be smaller than the gap between disagreeable men and disagreeable women).

NCBI ROFL: Parental behavior at kids' sports events.

By ncbi rofl | May 24, 2012 7:00 pm

Kids speak: preferred parental behavior at youth sport events.

“News reports and scholarly research have indicated increasing concern that parent-spectator behavior at youth sport events may be problematic. Multiple strategies have been used to influence spectator behavior in youth sport contexts (e.g., “Silent Sundays”). However it is unlikely that interventions aimed at changing parent-spectator behaviors have adequately considered young athletes’ perspectives, because little is known about how children want parents to behave during youth sport events.

NCBI ROFL: Finally, proof that pants are hotter than skirts.

By ncbi rofl | May 23, 2012 7:00 pm

The effects of two types of clothing on seasonal heat tolerance.

“The aim of this study was to look at changes in seasonal heat tolerance due to acclimatization produced by different types of clothing. A group of 12 female adults served as subjects in the study which lasted for 3 months from April to June during which the ambient temperature gradually rose. Of the group 6 of them (skirt group) wore knee-length skirts daily, and the others (trouser group) were dressed in full trousers during this acclimatization period. The heat tolerance before and after the acclimatization period was compared between the two groups under conditions in which relative humidity was 30% and ambient temperature was raised to 37 degrees C. Rectal temperature, mean skin temperature and the loss of body mass caused by sweating were measured in the two groups. Read More
