The urban neighborhood and cognitive functioning in late middle age

This study examines the association of cognitive functioning with urban neighborhood socioeconomic disadvantage and racial/ethnic segregation for a U.S. national sample of persons in late middle age, a time in the life course when cognitive deficits begin to emerge. The key hypothesis is that effects of neighborhood on cognitive functioning are not uniform but are most pronounced among subgroups of the population defined by socioeconomic status and race/ethnicity. Data are from the third wave of the Health and Retirement Survey for the birth cohort of 1931 to 1941, which was 55 to 65 years of age in 1996 (analytic N = 4,525), and the 1990 U.S. Census. Neighborhood socioeconomic disadvantage has an especially large negative impact on cognitive functioning among persons who are themselves poor, an instance of compound disadvantage. These findings have policy implications supporting "upstream" interventions to enhance cognitive functioning, especially among those most adversely affected by neighborhood socioeconomic disadvantage.     

The displaced and dispossessed of Darfur: explaining the sources of a continuing state-led genocide

The millions of survivors who fled from attacks to Sudanese-controlled displacement camps and the refugee camps in Chad are the living ghosts of the Darfur genocide. The 1948 Genocide Convention incorporates extermination by mass killing and elimination through forced migration as two distinct elements of genocide. Genocide scholars and public discourse emphasize extermination by killing, but they give far less explanatory attention to the elimination processes that the Genocide Convention describes as 'deliberately inflicting on the group conditions of life calculated to bring about its physical destruction'. (Article II United Nations 1948.) In Darfur, understanding the latter processes requires theoretical attention to the history of food, water, and famine and detailed methodological attention to temporal processes of displacement. We demonstrate how intentional state-led attacks on food and water massively dislodged Black Africans in Darfur from February 2003 to August 2004. The political leadership of the Sudanese state dehumanized and forcibly displaced Black Africans from their homes in Darfur to camps where they largely remain, not only through mass killings and rapes, but also by destroying life-sustaining access to food and water, leading to the genocidal elimination of group life in this region.     

Risk Taking in Late Adolescence: Relations Between Sociomoral Reasoning,Risk Stance,and Behavior

This study explored relations among late adolescents' sociomoral reasoning about risk taking, risk stance, and behavior. One‐hundred and thirty‐two participants (18–20‐year‐olds) were surveyed about their own risk stance (Avoidant, Opportunistic, Curious, Risk Seeking) and behavior in three realms (Alcohol Use, Drug Use, Reckless Driving), and sociomoral reasoning about hypothetical risk taking in a baseline scenario with no social domain information and a final scenario that highlighted the moral (i.e., harmful consequences for others), conventional (i.e., sociolegal consequences), personal (i.e., personal prerogative), and prudential (i.e., harmful consequences for self) domains bearing on risk taking. The complex relations among sociomoral reasoning about risk taking, risk stance, and behavior are discussed in terms of social domain theory and dual‐process theories of risk taking.     

Long‐Term Population Decline in Europe: The Relative Importance of Tempo Effects and Generational Length

It has recently been suggested that an end to further increases in the mean age of child‐bearing in Europe (ending the negative tempo effect on fertility) would have a substantial effect on population dynamics in terms of slowing population aging and decline and weakening the negative momentum affecting population size over the coming decades. On the other hand, stable population theory suggests that under sub‐replacement fertility conditions, a longer mean length of generations implies slower shrinking, and thus a relatively larger population in the very long run. This note compares the relative importance of the two effects analytically and with data for the 15‐country European Union. It also considers whether an increase in the mean age of childbearing will decrease the quantum of fertility. This question is highly relevant in the context of the effects of possible policies aiming to influence the tempo of fertility rather than the quantum directly. The results show that for the coming 200 years the effect of tempo changes clearly dominates, with the effect of a shorter mean length of generation only becoming visible thereafter. Even small tempo‐quantum interactions can overwhelm the generation‐length effect.     

Guestworker programs: Evidence from Europe and the United States and some implications for U.S. policy

Mounting concern in the United States over increased illegal migration from Mexico during the past decade has generated a heated policy debate and led to a number of proposals as to how the U.S. government should deal with the problem. Among these has been a call for a temporary worker program similar to the U.S.-sponsored Bracero Program (1942–1964) in which over 4 million Mexican workers were recruited to perform temporary agricultural labor in the southwestern United States. This article considers the implications of such a program by examining the social and economic effects of previous guestworker programs in the United States and western Europe from the perspective of both sending and receiving societies. Particular attention is paid to the efficacy of these programs in promoting temporary as opposed to long-term immigration of foreign workers as well as their developmental impact on sending countries.Now at 2405 Rayburn House Office Building, U.S. House of Representatives, Washington DC 20515.     

Brides N' Bumps

This paper accounts for the rise of a monolithic contemporary post-feminist pregnant bridal identity that is upheld and sold as the “ultimate” pleasure of femininity in Australia, the US, and the UK. I shall critically analyse the enfranchisement of the contemporary pregnant bride as a “new” consumer identity using the purchase of a maternity wedding dress as a key example. I argue that as pregnancy is already an experience deeply embedded in the marketplace, with this comes the added pressure for pregnant women to use bridal maternity clothing to conform to normative feminine bodily ideals. This claim is supported by interviews with a sample of Australian pregnant brides as part of a longitudinal qualitative study of pregnancy and body image. I conclude that as much as the pregnant bride challenges convention, in many ways, paradigms of femininity, in this context, remain ultimately unchanged and unchallenged.     

Using our brains to develop better policy

Current governmental practices often use a method called weight of evidence (WoE) to integrate and weigh different sources of information in the process of reaching a decision. Recent advances in cognitive neuroscience have identified WoE-like processes in the brain, and we believe that these advances have the potential to improve current decision-making practices. In this article, we describe five specific areas where knowledge emerging from cognitive neuroscience may be applied to the challenges confronting decisionmakers who manage risks: (1) quantifying evidence, (2) comparing the value of different sources of evidence, (3) reaching a decision, (4) illuminating the role of subjectivity, and (5) adapting to new information. We believe that the brain is an appropriate model for structuring decision-making processes because the brain's network is designed for complex, flexible decision making, and because policy decisions that must ultimately depend on human judgment will be best served by methods that complement human abilities. Future discoveries in cognitive neuroscience will likely bring further applications to decision practice.     

SELECTIVE ATTENTION AND LEARNING

What do we notice and how does this affect what we learn and come to believe? I present a model of an agent who learns to make forecasts on the basis of readily available information, but is selective as to which information he attends to: he chooses whether to attend as a function of current beliefs about whether such information is predictive. If the agent does not attend to some piece of information, it cannot be recalled at a later date. He uses Bayes' rule to update his beliefs given attended‐to information, but does not attempt to fill in missing information. The model demonstrates how selective attention may lead the agent to persistently fail to recognize important empirical regularities, make systematically biased forecasts, and hold incorrect beliefs about the statistical relationship between variables. In addition, it identifies factors that make such errors more likely or persistent. The model is applied to shed light on stereotyping and discrimination, persistent learning failures and disagreement, and the process of discovery.

Coal demand,market forces,and U.S. coal mine closures

Economic transitions have the potential to displace workers and cause social unrest. Coal mine closures and the resulting employment losses in rural areas have become salient issues. Using data on coal mine and power plant operation, we model closure as a function of expected profits, which allows us to compare the effects on mine closure of specific demand and supply shocks to expected mine profits. Increasing costs of production have had a large impact on closures, but lower natural gas prices and lower electricity demand have played more recently important roles.
