Rhodium/phospholane-phosphite catalysts give unusually high regioselectivity in the enantioselective hydroformylation of vinyl arenes
Using the phospholane-phosphite ligand, BOBPHOS, almost perfect regioselectivities and high enantioselectivities (up to 92% ee) are observed in Rh catalysed enantioselective hydroformylation of vinyl arenes. This can be achieved under solvent-free conditions.PostprintPeer reviewe

Perinatal maternal and neonatal behaviour in the captive reticulated giraffe
A captive reticulated giraffe was observed constantly for three weeks prior to, and periodically for 90 days subsequent to, the birth of her calf. Extensive observations were made of the birth sequence, feeding, drinking, sleeping and one instance of an infant distress call, as well as observations of the initiation of maternal behaviour (including licking, nursing, placentophagia, and what appeared to be helping the calf to stand, guiding the calf's movements, and attempts to respond to the calf's distress call).'n Kameelperdkoei in gevangeskap is onafgebroke vir drie weke voor en periodiek vir 90 dae na die geboorte van haar kalf dopgehou. Noukeurige waarnemings is gedoen van die geboorteproses, die voeding, soog, slaap en, op een geleentheid, van die noodroep van die kalf. Verdere waarnemings is ook gedoen ten opsigte van die aanvang van moedergedrag insluitend die lek en oppas van die kalf, verwydering van die plasente, optrede wat voorgekom het as hulp aan die kalf om te staan, stuur van die kalf in sy bewegings en reaksie op die noodroep van die kalf

Arts Districts, Universities, and the Rise of Digital Media
In the last decade, arts and culture have been placed at the center of attention when discussing economic growth. In particular, studies on the âcreative classâ have been using arts and culture as an important factor impacting local economies. In addition, studies on local economic development have frequently viewed universities as a major factor in economic growth. In the middle of this discussion is new economic growth via creativity, via new recipes and new combinations of local capital, and via innovation centers. Combining these disparate literatures brings to center stage both clusters of arts and culture and concentrations of research and human capital development. Hence, the focus of this paper is to analyze the dual impacts of universities and arts districts on innovation and economic growth through employment in digital media. The results indicate that cultural districts have a consistently positive effect on local digital media economic activityâemployment and innovation. The same cannot be said for research universities
