Transition from socialist to capitalist economy led to enormous changes in earnings and employment. In our study a long-horizon descriptive analysis is presented about the major trends, including the last fifteen years of socialism. Education, gender, calendar time, age and vintage effects are separately analyzed. Aggregate (quasi-) panel analysis is used to assess the role of labor demand and ...

This letter deals with the problem of fluctuating target detection in heavy-tailed -distributed clutter over a number of independent coherent intervals, e.g., in the case of a long observation interval (“stare mode”), or that of independent (range) resolution cells as per the track before detect techniques. The generalized likelihood ratio test for the problem at hand is derived, as well as an ...

Dynamical, self-organizing models of sentence processing predict "digging-in" effects: The more committed the parser becomes to a wrong syntactic choice, the harder it is to reanalyze. Experiment 1 replicates previous grammaticality judgment studies (F. Ferreira & J. M. Henderson, 1991b, 1993), revealing a deleterious effect of lengthening the ambiguous region of a garden-path sentence. The aut...

Fossorial rodents damage lawns/water impoundments/crops. We conducted a two-choice, parametric-type study to determine the effects of capsicum-oleoresin/soil mixtures (0.00, 0.75, 1.50, and 2.25%) upon soil-contact, soil-digging, and pelage-grooming behaviors in northern pocket gophers (Thomomys talpoides). In 3 alternate-day (1-h/day) exposures to > or = 1.50% capsicum-oleoresin soil mixtures,...
