The relationship between the frequency and the processing complexity of linguistic structure

In this paper the relative frequencies of the possible resolutions of ambiguities involving noun phrase attachment sites are compared to the results of off-line psycholinguistic measurements of syntactic complexity. A lack of correlation between the two is observed. It is therefore argued that the comprehension system is distinct from what is driving the frequencies in the corpora. A production heuristic separate from the comprehension system is proposed to account for the observed frequencies.We would like to thank Susanne Tunstall for providing linguistic judgments in the corpus analyses reported in Sec. 3.3.

Restorying family therapy

This article describes a multi-systemic model of therapy developed by the author over the past decade and summarizes the main products of this project: Explication of key family systems notions, strategic family play therapy, multi-systemic therapy, and culturally-competent family therapy. The model incorporates beyond the family system, culture, wider ecosystems, psychodynamics, and the individual's neuropsychological, cognitive, and socio-emotional development. The model enables the therapist to design flexible multimodal interventions.     

The perceived strength of illusory contours.

Illusory contours are not well understood, partially because a lack of physical substance complicates their specification via physical standards. One solution is to gauge illusory contours with respect to luminance-defined contours, which are easily quantified physically. Accordingly, we chose a metric (perceived contrast) that expresses illusory contour strength in terms of the physical contrast of luminance-defined contours. Using this metric, adult observers adjusted the contrast of a luminance-defined contour until it matched the perceived contrast of an illusory contour. Illusory contour length, inducer size, and inducer contrast all influenced illusory contour strength. The results are adequately explained via low-level visual processes. It appears that matching paradigms can be beneficial in quantitative studies of illusory contours.     

Occupational stress. Spice of life or kiss of death?

Work-related psychosocial stressors originate in social structures and processes, affect the human organism through psychological processes, and influence health through four types of closely interrelated mechanisms--emotional, cognitive, behavioral, and physiological. The health outcome is modified by situational (e.g., social support) and individual factors (e.g., personality, coping repertoire). The work-environment-stress-health system is a dynamic one with many feedback loops. There is little but increasing direct evidence of a causal relationship between work-related psychosocial stressors and the incidence and prevalence of occupational morbidity and mortality. But, a substantial body of indirect evidence strongly suggests that such associations exist and emphasizes the need to better understand their role. Accordingly, research and health action should aim at being systems-oriented, interdisciplinary, intersectorial, health- (and not only disease-) oriented, and participative.     

The Association of Religiosity and Political Conservatism: The Role of Political Engagement

Some argue that there is an organic connection between being religious and being politically conservative. We evaluate an alternative thesis that the relation between religiosity and political conservatism largely results from engagement with political discourse that indicates that these characteristics go together. In a combined sample of national survey respondents from 1996 to 2008, religiosity was associated with conservative positions on a wide range of attitudes and values among the highly politically engaged, but this association was generally weaker or nonexistent among those less engaged with politics. The specific political characteristics for which this pattern existed varied across ethno‐religious groups. These results suggest that whether religiosity translates into political conservatism depends to an important degree on level of engagement with political discourse.     

Would you Value a few More Hours of work? Underemployment and Subjective Well-Being Across Chilean Workers

Underemployment has gained attention in recent years because of its effects on health and well-being (life satisfaction), it is a widespread phenomenon in the labor force that affects not only workers, but also households, companies and governments. This paper explores the relationship between underemployment and subjective well-being for a representative sample of Chilean workers using an ordered probit model. Also, by using different underemployment definitions and a latent class ordered probit model we analyze the observed and unobserved heterogeneity in this relationship. Finally, we assess the monetary valuation of well-being costs by estimating the amount of money that a worker is willing to accept in order to bear the potential negative effects of underemployment on well-being. Our results find a negative relationship between underemployment and subjective well-being, as the average worker is willing to accept an increase of CLP$64,009 (roughly 30.5% of the minimum wage) in her/his monthly wage for being underemployed. If we take into account the observed and unobserved heterogeneity, our results identify a group that is not sensitive to underemployment, while others are willing to accept an increase of CLP$146,622 in her/his monthly wage for being underemployed. Our work highlights the importance of well-being in the workplace and has implications for labor flexibility legislation and the empowerment of workers. Heterogeneous responses to underemployment imply that one-size-fits-all policies to regulate working hours might not suffice.

     

An Empirical Investigation of Partial Effect Sizes in Meta-Analysis of Correlational Data

ABSTRACT. The partial correlation and the semi-partial correlation can be seen as measures of partial effect sizes for the correlational family. Thus, both indices have been used in the meta-analysis literature to represent the relationship between an outcome and a predictor of interest, controlling for the effect of other variables in the model. This article evaluates the accuracy of synthesizing these two indices under different situations. Both partial correlation and the semi-partial correlation appear to behave as expected with respect to bias and root mean squared error (RMSE). However, the partial correlation seems to outperform the semi-partial correlation regarding Type I error of the homogeneity test (Q statistic). Although further investigation is needed to fully understand the impact of meta-analyzing partial effect sizes, the current study demonstrates the accuracy of both indices.
