Specificity of phonological representations in U.S. English-speaking late talkers and typical talkers

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.     

The imbalance of sex-hormones related to depressive symptoms in obese men

Obese men may present hypogonadothrofic hypogonadism, mainly related to higher insulinemia and aromatase activity. Our objectives were to evaluate the relationship of sex-hormones profiles and frequency of depressive symptoms in 43 obese men, in a cross-sectional study. They had 19–60 years, and body mass index 30–50?kg/m². LH, total and free testosterone (TT and FT), estradiol (E₂), sex hormone binding globulin, estradiol/total testosterone ratio (E₂/T) were analyzed. Depressive symptoms were evaluated by “beck depression inventory” (BDI), and significant depression was considered if BDI?≥?16.Thirty-four (80%) presented low TT levels, but only 4 (14%) had low free testosterone and hypogonadism symptoms; 12 of 43 (28%) presented increased E₂. Forty five (56%) presented depressive symptoms, but 16 (28% of the 45) had significant depression. BDI correlated positively with E₂ (r?=?0.407; p?=?0.001) and E₂/T (r?=?0.473; p?=?0.001), but not TT or FT. Patients with significant depressive showed higher levels of estradiol (136?±?48 versus 103?±?48?pg/ml, p?=?0.02) and E₂/T (16.0?±?9.9 versus 9.8?±?4.6; p?=?0.002) (mean?±?SD).In conclusion, obese men may present relatively excess of estradiol and deficiency in testosterone, leading to an imbalance between these two hormones. The greater this imbalance, the more depressive symptoms had our patients.     

Mothers, Fathers, Peers, and Mexican-Origin Adolescents' Sexual Intentions

Drawing on a symbolic-interaction perspective and a compensation model, the processes linking mother-and father-adolescent relationship qualities, deviant peer affiliations, and adolescents' sexual intentions were investigated for 246 Mexican-origin youths born in the United States and in Mexico using multiple-group structural equation models. Deviant peer affiliations significantly mediated the relations between paternal acceptance and sexual intentions and between disclosure to mothers and sexual intentions for U.S.-born youths but not for Mexico-born youths. Findings highlight the importance of examining variability as a function of youth nativity.     

Performance Evaluation in Non-Governmental Organizations (NGOs): An Analysis of Evaluation Models and their Applications in Brazil

The objective of this article is to deepen the debate surrounding the practice of evaluation as performed by Brazilian NGOs. In order to accomplish this goal, we examined the results of an investigation conducted between 2007 and 2009 that had two stages: first, a national study and second, a quantitative and qualitative study made in the state of Santa Catarina. We also considered secondary sources of data from two important studies on the national level that were conducted in 2008 and 2009 by the Fonte Institute, with partnership of the Itaú Social Foundation. The results showed that most NGOs use internal rather than external evaluation and conduct evaluations focused on projects and programs. Furthermore, they used evaluation mainly to help decision making about projects. Consequently, the majority of NGOs focused their evaluations on results and were not concerned with creating spaces for self-reflection and learning.     

Labour Surplus,Worker Rights and Productivity Growth: A Comparative Analysis of Asia and Latin America

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.
