The effect of the original introduction of Medicaid on welfare participation and female labor supply

This paper uses the fact that states introduced Medicaid programs at different times between 1966 and 1972 to estimate Medicaid??s effect on Aid to Families with Dependent Children (AFDC) participation. Using state-level data, we find that the introduction of Medicaid accounted for approximately 10% of growth in AFDC caseloads from 1964 to 1974, a time period during which there was thought to be significant unexplained growth in caseloads. Analysis of individual-level data indicates that Medicaid??s effect on AFDC participation occurred through its effect in increasing the number of eligibles who participated in the program, and not because of increases in eligibility or reductions in workforce participation.     

New Approaches to Human Mobility: Using Mobile Phones for Demographic Research

This article explores new methods for gathering and analyzing spatially rich demographic data using mobile phones. It describes a pilot study (the Human Mobility Project) in which volunteers around the world were successfully recruited to share GPS and cellular tower information on their trajectories and respond to dynamic, location-based surveys using an open-source Android application. The pilot study illustrates the great potential of mobile phone methodology for moving spatial measures beyond residential census units and investigating a range of important social phenomena, including the heterogeneity of activity spaces, the dynamic nature of spatial segregation, and the contextual dependence of subjective well-being.     

A semiotic approach to ‘ethnicity’. An example from Taiwanese ‘Chineseness’

For a few decades, socio-cultural as well as linguistic anthropologists have worked hard to construct a reliable semiotic paradigm to study linguistic, cultural and social interactions. These subfields – linguistic, cultural and social – are often analytically tackled asunder, though they are intimately interconnected, intertwined and overlapping. The semiotic theory of culture is not a novel discovery in itself, but it can also be applied to the study of society and ethnicity. Culture, society and ethnicity are systems of communication, that is systems of signs; society is a system of signs whose meaning emerges from social interactions and ethnicity a system of signs whose meaning is strategically imposed by a specific society through a specific culture. Moreover, those three systems of communication, of signs, are interconnected in various ways. This essay will analyze ‘Taiwanese Ethnicity’ in its semiotic dimension, and explore how society, culture and ethnicity interact in constructing an ethnic identification.     

The Working Families’ Tax Credit and Some European Tax Reforms in A Collective Setting

A framework for simplified implementation of the collective model of labor supply decisions is presented in the context of fiscal reforms in the UK. Through its collective form the model accounts for the well known problem of distribution between wallet and purse, a broadly debated issue which has so far been impossible to model due to the limitations of the unitary model of household behavior. A calibrated data set is used to model the effects of introducing two forms of the Working Families’ Tax Credit. We also summarize results of estimations and calibrations obtained using the same methodology on data from five other European countries. The results underline the importance of taking account of the intrahousehold decision process and suggest that who receives government transfers does matter from the point of view of labor supply and welfare of household members. They also highlight the need for more research into models of household behavior.

Collective Models of Labor Supply with Nonconvex Budget Sets and Nonparticipation: A Calibration Approach

We suggest a methodology to calibrate a collective model with household-specific bargaining rules and marriage-specific preferences that incorporate leisure externalities. The empirical identification relies on the assumption that some aspects of individual preferences remain the same after marriage, so that estimation on single individuals can be used. The procedure maps the complete Pareto frontier of each household in the dataset and we define alternative measures of a power index. The latter is then regressed on relevant bargaining factors, including a set of variables retracing the potential relative contributions of the spouses to household disposable income. In its capacity to handle complex budget sets and labor force participation decisions of both spouses, this framework allows the comparison of unitary and collective predictions of labor supply reactions and welfare changes entailed by fiscal reforms in a realistic setting (see Michal Myck et al., 2006; Denis Beninger et al., 2006).

Homophobia: a challenge for psychosocial nursing

1. In 1975, the American Psychological Association stated that homosexuality was not a disorder and that homophobia was a form of prejudice based on stereotypes. 2. Because homophobia, like racism or sexism, is learned, it can be unlearned. 3. People who feel homosexuality is a choice hold more negative attitudes toward individuals who are gay, lesbian, bisexual, or transgendered. 4. Homophobia not only damages individuals who are gay, lesbian, bisexual, or transgendered, but also limits heterosexuals by locking them into rigid gender-based roles.
