Probabilistic feature analysis of facial perception of emotions

Summary.  According to the hypothesis of configural encoding, the spatial relationships between the parts of the face function as an additional source of information in the facial perception of emotions. The paper analyses experimental data on the perception of emotion to investigate whether there is evidence for configural encoding in the processing of facial expressions. It is argued that analysis with a probabilistic feature model has several advantages that are not implied by, for example, a generalized linear modelling approach. First, the probabilistic feature model allows us to extract empirically the facial features that are relevant in processing the face, rather than focusing on the features that were manipulated in the experiment. Second, the probabilistic feature model allows a direct test of the hypothesis of configural encoding as it explicitly formalizes a mechanism for the way in which information about separate facial features is combined in processing the face. Third, the model allows us to account for a complex data structure while still yielding parameters that have a straightforward interpretation.     

Theorizing notions of the participation of people in poverty in social policymaking: Policing,politics and subjectification

Since the 1990s, a paradigm of participation has gained prominence and become a dominant policy rhetoric in anti-poverty policymaking in Europe, embracing the key idea that people in poverty should participate as equal citizens in political decision-making processes. Based on a historical case study of the production process of a Belgian white paper, the General Report on Poverty (1994), we investigate who participated in the GRP production process, and whether the underlying participatory and democratic mechanisms produced a shift in power and might have led to a more socially just and equal society. We rely on a central set of ideas of the French philosopher Jacques Rancière to theorize different notions of participation, and tease out whether the processing of equality had the capacity to move from policing towards politics through subjectification. Our research study demonstrates how social change and a reconfiguration of the democratic order can appear as a moment of democracy, yet inevitably leads to a new police.     

Community-level determinants of contraceptive use in the Philippines: A structural analysis

We use household and community data from the Philippines to estimate a multilevel model of contraceptive use. We go beyond previous efforts in this field by developing a structural model that recognizes joint endogeneity and the temporal ordering of variables, by considering a wider range of community influences on fertility behavior, and by employing an econometric procedure allowing for a multilevel error structure. The results suggest that there are significant effects on fertility behavior of community-level family planning services, labor-market conditions, and infrastructure development. These results provide insights regarding the structural determinants of contraceptive use and fertility that are useful for drawing policy implications.     

Children's education in the Phillipines: Does high fertility matter?

This paper examines the effects of family size and sibling position on children's current school enrollment status in the Philippines. The theoretical framework focuses on the determinants of children's participation in alternative activities, specifically schooling, market work, and home production. This approach allows for a greater understanding of the mechanisms through which fertility, as reflected by number of siblings and sibling composition, influences children's education than would examining the determinants of schooling alone. The model is estimated using the 1983 wave of the Bicol Multipurpose Survey. The results indicate the existence of negative effects of fertility on school enrollment, which, in part, operate through work status. In addition, these effects differ according to the sibling position of the child.     

On opulence driven poverty traps

Endogenous population growth, i.e., making the rate of population growth dependent on society's opulence, causes parametric changes to have a larger impact and can cause multiplicity of steady states in a dynamic intertemporal optimization framework. This provides a simple explanation for the possibility of differing growth paths between countries (using a standard production function) or another explanation of the poverty trap. We give two examples (opulence sensitivity and production sensitivity) that both give rise to three steady states in which poor (rich) countries will evolve over time to the low (high) income steady state. In both examples there are middle income countries that will choose the low (high) income steady state if they are impatient (patient), where patience is measured through the rate of time preference o. Foreign aid in the form of a large transfer of capital from abroad enables poor and impatient middle income countries to move to the high income steady state.We would like to thank Nico Heering, Martijn Herrmann, Theo Junius, Ngo van Long, Ad Pikkemaat, John Pitchford, Lakshmi Raut, Casper de Vries, an anonymous referee, participants of workshops at the University of Groningen and the University of Amsterdam and especially Harry van Dalen for valuable comments.

Circular, invisible, and ambiguous migrants: components of difference in estimates of the number of unauthorized Mexican migrants in the United States

Based on an equation that can be used with available data and that provides a basis for facilitating decomposition analyses, this research estimates that about 2.54 million total (as opposed to enumerated) unauthorized Mexicans resided in the United States in 1996. Comparing this figure with an estimate of about 2.70 million released by the U.S. Immigration and Naturalization Service (INS) during the 1990s, we find that the two estimates involve different assumptions about circular, invisible, and ambiguous migrants. Such differences not only can have important policy implications; they can also be sizable and can operate in opposite directions, as illustrated by findings from a components-of-difference analysis. The results are also extrapolated to 2000, and implications for 2000 census counts are discussed.     

Public policy and the labor market adjustment of new immigrants to Australia

Two separate cohorts of immigrants to Australia are compared in order to assess the potential role of immigrant selection criteria, labor market conditions, and income-support policy in facilitating the labor market adjustment of new arrivals. Although these two cohorts entered Australia only five years apart, their initial labor market outcomes varied dramatically. The results indicate that changes in immigration policy may have led to increased human capital endowments that in turn resulted in higher participation rates and reduced unemployment. At the same time, improvement in Australian labor market conditions and changes in income-support policy over the 1990s – which most likely altered the returns to human capital – were probably instrumental in reinforcing the effects of tighter immigrant selection criteria. As much as half of the fall in unemployment rates among women and one third the decline among men appears to have occurred as the result of changes in the returns to demographic and human capital characteristics.

A decomaosition of trends in poverty among children of immigrants

Poverty levels among all children in the United States have tended to fluctuate in the past 30 years. However, among the children of immigrants, child poverty increased steadily and rapidly from about 12% in 1970 to 33% in the late 1990s before declining to about 21% in 2000. Using 1970, 1980, 1990, and 2000 Public Use Microdata Samples data, we identified key factors that underlie the fluctuations in immigrant child poverty from 1969 to 1999 and the divergence from children of natives. We found that roughly half the absolute increase in immigrant child poverty can be linked to changing conditions in the U.S. economy that make it more difficult to lift a family out of poverty than 30 years ago. These changes occurred disproportionately among children of parents with lower levels of education, employment, and U.S. experience but not among racial/ethnic minorities. Poverty risks among various racial and ethnic groups converged over time. The relative increase in poverty for immigrant versus native children owes largely to the divergence between immigrant and native families in racial/ethnic composition, parental education, and employment.     

On the Preference to Avoid Ex Post Inventory Errors

The value of demand information underlies many supply chain strategies that aim at better matching supply and demand. This study reports on the results of a laboratory experiment designed to estimate the behavioral value of demand information. Relative to the commonly assumed benchmark of a rational risk‐neutral decision maker, we find that decision makers are consistently willing to pay too much for the option to eliminate the risk of supply not matching demand. Contrary to intuition, we show that risk aversion does not explain this result. We posit that demand information provides behavioral value because it mitigates regret from ex post inventory errors.
