BACKGROUND This study is the first cost-benefit analysis (CBA) of occupational health and safety (OHS) in a low-income country. It focuses on one of the largest shipbuilding companies in Bangladesh, where globally recognised Occupational Health and Safety Advisory Services (OHSAS) 18001 certification was achieved in 2012. OBJECTIVES The study examines the relative costs of implementing OHS me...

A new synthetic method for chiral oxazolidinone derivatives, therapeutic agents for treating urinary disturbance, is described. The condensed compound obtained from chiral 1-amino-3-phenyl-2-propanol and 1-phenyl-3-morpholino-1-propanone was reduced with Me4NBH(OAc)3 to give the intermediate, 1-(3-morpholino-1-phenylpropyl)amino-3-phenyl-2-propanol (MAPP) in 34% diastereomeric excess (d.e.). MA...

The basal ganglia control body movements, value processing and decision-making. Many studies have shown that the inputs and outputs of each basal ganglia structure are topographically organized, which suggests that the basal ganglia consist of separate circuits that serve distinct functions. A notable example is the circuits that originate from the rostral (head) and caudal (tail) regions of th...

In England in 1800 a profound change occurred that ushered in an important component in the regime of modern economic growth. In pre-industrial England, from 1250 to 1800, the rich produced many more surviving children than the poor. From 1800 to 1875 there was no association between wealth and net fertility. And after 1875 wealth became strongly negatively associated with net fertility. Why th...
