This study investigated the effects of introducing a family planning counseling model at clinics of Peru's Ministry of Health. Providers trained in the model presented greater quality of care and longer counseling sessions than did controls. The main effects, however, were misleading. Nearly all of the quality improvements were contributed by 37% of the trained providers; they had already been better performers at the pretest and complied with the new counseling model's requirement of job aid use at the posttest. The recognition that a majority of trained providers did not profit from training posed a challenge that led to improvements in the model. Training x Trainee Interactions should be explored in evaluations.  相似文献

Although Colombia is a major country of emigration, little is known about its citizens' motivations for migration. Social and economic conditions have been studied as determinants of migration, but violence has received less attention. We examine how social networks and violence function to promote emigration from Colombia by linking event‐history data from the Latin American Migration Project to external data on violence and economic conditions. We show that emigration is more likely to be initiated by those with higher education, those with network connections to migrants, and during periods of greater violence and increased police presence. Although violence acts powerfully to determine when people migrate, the geographic distribution of social capital determines where they go. Not surprisingly, migrants go to locations where people in their social networks are currently living or have been earlier.  相似文献

Late talkers are a heterogeneous group of children who experience delayed language development in the absence of other known causes. Late talkers show delays in expressive phonological development, but less is known about their receptive phonological development. In the current study, U.S. monolingual English-speaking typical talkers (TTs) (n = 23, mean age = 26.27 months, 57% male; 78.3% White) and late talkers (n = 22, mean age = 24.57 months, 59% male, 72.7% White) completed a Looking-While-Listening task to assess their sensitivity to mispronunciations. Results revealed that late talkers and TTs looked to the referent of a word for a shorter duration when it was mispronounced than when it was correctly pronounced, suggesting they were sensitive to mispronunciations. However, there were no significant differences between the two groups in their sensitivity to mispronunciations.  相似文献

How do labour market conditions, trade union rights and job security regulations affect labour productivity? This paper is the first attempt at an empirical analysis of this important question for a large sample of Asian and Latin American countries. We provide new estimates of the rates of surplus labour in 20 countries, as well as detailed tables summarizing their key regulations governing certain aspects of union activity and layoffs. Then we exploit these and other data in an econometric analysis of intercountry differentials in the growth rate of labour productivity in manufacturing during the 1980s. Among the principal results, we find that, while all else remains the same, productivity growth rates are significantly higher in countries with relatively larger labour surpluses, the effects of excess of labour on productivity growth are affected by the strength or weakness of union rights. We also find that the impacts of union rights and job security protections on productivity trends may be either positive or negative, depending on the labour market situation.  相似文献
