Previous research has shown that school enrollment in developing countries responds to the changes in return to education generated by a change in demand in the export sector, that pays higher wages for a given skill level. Using data from Mexico, I show that the negative effects of a lower return to education are not limited to lower rates of school enrollment. Parents also respond to a decrea...

Sera from 30 patients with inflammatory bowel disease (IBD) (16 with Crohn's disease (CD) and 14 with ulcerative colitis (UC) were assayed for the presence of antibodies against 159 Escherichia coli O-antigens and compared with sera from 16 matched control subjects. The majority of patients with IBD had agglutinating antibodies to a higher number of Escherichia coli O-antigens and in higher tit...

The purpose of this study is to empirically test the validity of Kaldor’s laws of economic growth in China between 1978 and 2004 and to provide an alternative explanation of sources of Chinese economic growth in a Kaldorian perspective. First, in a spatial econometrics perspective using a regional data set, the present paper empirically verifies that Kaldorian hypotheses on economic growth hold...

This paper shows how agricultural productivity shocks can generate large industrial output fluctuations in poor countries, using a static general-equilibrium model with Stone-Geary preferences. A negative shock to agricultural productivity increases food prices, which affects manufacturing output through two channels: (1) meeting subsistence requirements in the face of rising food prices causes...

Lipopolysaccharide O antigens (endotoxins) and other bacterial antigens readily attach to erythrocytes in vitro. This attachment is prevented by certain mammalian and avian sera. In this study, the inhibitory capacity of sera from lower animals was compared with that of higher animals for a total of 30 species. Antigens and the corresponding antisera included both crude O antigens and purified ...
