Professional soccer players have a lengthy playing season, throughout which high levels of physical stress are maintained. The following recuperation period, before starting the next pre-season training phase, is generally considered short but sufficient to allow a decrease in these stress levels and therefore a reduction in the propensity for injury or musculoskeletal tissue damage. We hypothe...

I consider a retailer who sells a new product over two periods: advance and regular selling seasons. Experienced consumers learn their valuations for the product in the advance selling season, while inexperienced consumers learn only when the product becomes available in the regular selling season. The retailer is uncertain about the number of inexperienced consumers. Production takes place bet...

Twice a year, normally diurnal songbirds engage in long-distance nocturnal migrations between their wintering and breeding grounds. If and how songbirds sleep during these periods of increased activity has remained a mystery. We used a combination of electrophysiological recording and neurobehavioral testing to characterize seasonal changes in sleep and cognition in captive white-crowned sparro...

What constitutes audience engagement? What elements of a show produce the most social activity? Much attention has been paid to Twitter’s ability to capture real-time audience reactions and sentiment towards a television show, but little is known about what subjects drive an individual to tweet (or conversely, not to tweet). Though common sense may suggest that especially provocative, humorous,...

Predicting the grass dry matter intake (GDMI), milk yield (MY) or milk fat and protein yield (milk solids yield (MSY)) of the grazing dairy herd is difficult. Decisions with regard to grazing management are based on guesstimates of the GDMI of the herd, yet GDMI is a critical factor influencing MY and MSY. A data set containing animal, sward, grazing management and concentrate supplementation v...

The winter use of standing dead biomass produced by warm season grasses during the previous growing season may be an alternative to grazing systems in the semi-arid Pampean Region of Argentina. This study evaluated: 1) the effect of different deferment periods on the leaf blade percentage and quality of ‘kleingrass’ (Panicum coloratum L.), a warm season specie recently introduced to that region...

The effects of sex, injuries, season and site on the growth of the spiny lobsters Panulirus gracilis, and P. inflatus, were studied through mark-recapture techniques in two sites with different ecological characteristics on the coast of Guerrero, México. Panulirus gracilis occurred in both sites, whereas P. inflatus occurred only in one site. All recaptured individuals were adults. Both species...

Mud Recycle is a process option for cane diffuser factories; it eliminates the need for a filter station by using the bed of shredded cane in the diffuser to separate out mud solids from the juice. This paper describes the Mud Recycle system at Maidstone mill and presents the results of a Mud Recycle trial that was carried out during the 1998 season. Maidstone switched to Mud Recycle on a perma...

This study evaluated the invariance properties of the Leadership Scale for Sport in a sample of 219 female netball players over four time points within a 10-week playing season. Support was found for Chelladurai and Saleh’s (1980) >hypothesized 5-factor structure of the Leadership Scale for Sport. Furthermore, differential stability and partial invariance was found for the Leadership Scale for ...

Halyomorpha halys is an introduced stink bug species from Asia that is spreading throughout the Mid-Atlantic United States. It is native to South Korea, Japan, and eastern China, where it is an occasional pest of tree fruit, including apple and pear. Cage experiments with adults placed on apple and peach during critical plant growth stages demonstrate that it can cause damage to developing frui...
