Effectiveness of Taxicab Security Equipment in Reducing Driver Homicide Rates

submitted by: NIOSHcomm
Background: Taxicab drivers historically have had one of the highest work-related homicide rates of any occupation. In 2010 the taxicab driver homicide rate was 7.4 per 100,000 drivers, compared to the overall rate of 0.37 per 100,000 workers. Purpose: Evaluate the effectiveness of taxicab security cameras and partitions on citywide taxicab driver homicide rates. Methods: Taxicab driver homicide rates were compared in 26 major cities in the U.S. licensing taxicabs with security...

MWV Episode 72 - Jonathan Eisen - Evolvability, the Built Environment and Open Science

submitted by: MicrobeWorld
Jonathan Eisen is an evolutionary biologist, currently working at University of California, Davis and is the academic editor-in-chief of the open-access journal PLoS Biology. On this episode, Jonathan talks about "evolvability," the probability that organisms can invent new functions. To do this, he has been using genome data in conjunction with experimental information to try and understand the mechanisms by which new functions have originated. Another area of interest for Eisen is the...

Consumer attitudes and understanding of low sodium claims on food: An analysis of healthy and hypertensive individuals

submitted by: Christina.L.Wong
Background: Sodium-related claims on food labels should facilitate lower-sodium food choices; however, consumer attitudes and understanding of such claims are unknown. Objectives: We evaluated consumer attitudes and understanding of different types of sodium claims and the effect of having hypertension on responses to such claims. Design: Canadian consumers (n = 506), with and without hypertension, completed an online survey that contained a randomized mock package experiment, which...

Effect of preterm birth and birth weight on eating behavior at 2 years

submitted by: valama
ABSTRACT Background: Preterm infants frequently present eating difficulties in early childhood. Determinants of these difficulties are not known. Objective: We assessed the influence of neonatal and maternal characteristics on eating behaviors at 2 y of age. Design: The following 2 cohorts were compared: 234 preterm children born ,33 wk of gestational age from the POLYmorphisme ge´ne´tique, Nutrition et Comportement Alimentaire cohort and 245 term children from the Observation des...

biosights: May 13, 2013 - Ventral lamellipodia plug the gaps

submitted by: JCB
When leukocytes enter or exit the blood stream, they leave small wounds both in and between the vascular endothelial cells, which must be quickly repaired so that the endothelium can maintain its barrier function. Martinelli et al. reveal that wounding causes a loss of tension in endothelial cells, inducing the formation of ventral lamellipodia that close the holes left by transmigrating leukocytes. This biosights episode presents the paper by Martinelli et al. from the April 29, 2013, issue...

biosights: April 15, 2013 - Frog oocytes evade the checkpoint

submitted by: JCB
Most dividing cells possess a spindle assembly checkpoint that prevents them from entering anaphase until all their chromosomes are correctly attached to the metaphase spindle. Shao et al. reveal that Xenopus eggs lack this checkpoint, allowing them to undergo meiosis in the absence of microtubules or in the presence of monopolar spindles. This biosights episode presents the paper by Shao et al. from the April 15, 2013 issue of The Journal of Cell Biology and includes an interview with...
