Histomorphometric indices of the pancreas in intoxication with alcohol and narcotics

The results of histomorphometric examinations of the pancreas in drug- and alcohol-addiction as well as in acute intoxications are described. They show that, in chronic alcoholic intoxication as compared with opiomania, there are more pronounced interlobular sclerosis and lipomatosis, which is manifested by an enlarged middle lobe of the stroma (containing fat and connective tissue fibers), by a higher density of islands of Langerhans and by their higher sectional area. Autolysis and edema of the stroma are more severe in an acute intoxication with drugs than in other cases of fatal outcome. A possibility is demonstrated to differentiate between various types of the so-called long-term exogenous intoxication and to discriminate between different types of thanatogenesis typical of various cases of acute intoxications. Data are presented that demonstrate the advantage of the quantitative analysis of histological preparations over the qualitative one.     

Using Ecological Inference Point Estimates as Dependent Variables in Second-Stage Linear Regressions

The practice of using point estimates produced by the King ecologicalinference technique as dependent variables in second-stage linearregressions leads to second-stage results that, in general,are inconsistent. This conclusion holds even when all assumptionsbehind King's ecological technique are satisfied. Second-stageinconsistency is a consequence of the fact that King-based pointestimates of disaggregated quantities contain errors correlatedwith the true quantities the estimates measure. Our findingson second-stage inconsistency, as well as a fix that we propose,follow from econometric theory in conjunction with an analysisof simulated and real ecological data sets.     

The poor in Singapore: issues and options

This article examines the changing patterns of poverty in Singapore. As Singapore's population ages, the poor increasingly includes the elderly. It appears that ascribed factors, such as gender and race, have significant influence on financial security at old age. As the population ages, the adequacy of existing anti-poverty policy is challenged.
