This chapter outlines the evolution of Mexico’s payments for hydrological services program from its inception through the first two years of the program’s implementation. Background information on forests, deforestation, and potential environmental services provide context for a political economy analysis of the path the program traveled through Mexico’s legislative and administrative structures. We also analyze the characteristics of the recipients during the first two years, including results from a survey of participants and community case studies. A final section extracts lessons from the Mexican experience, including possible alternative program designs to address some of the problems encountered in its implementation

The understanding of decision-making systems has come together in recent years to form a unified theory of decision-making in the mammalian brain as arising from multiple, interacting systems (a planning system, a habit system, and a situation-recognition system). This unified decision-making system has multiple potential access points through which it can be driven to make maladaptive choices, particularly choices that entail seeking of certain drugs or behaviors. We identify 10 key vulnerabilities in the system: (1) moving away from homeostasis, (2) changing allostatic set points, (3) euphorigenic “reward-like” signals, (4) overvaluation in the planning system, (5) incorrect search of situation-action-outcome relationships, (6) misclassification of situations, (7) overvaluation in the habit system, (8) a mismatch in the balance of the two decision systems, (9) over-fast discounting processes, and (10) changed learning rates. These vulnerabilities provide a taxonomy of potential problems with decision-making systems. Although each vulnerability can drive an agent to return to the addictive choice, each vulnerability also implies a characteristic symptomology. Different drugs, different behaviors, and different individuals are likely to access different vulnerabilities. This has implications for an individual’s susceptibility to addiction and the transition to addiction, for the potential for relapse, and for the potential for treatment.

The role of Implicit motivation to Control prejudice (ImCp) in moderating
the effect of resource depletion on spontaneous discriminatory behavior
was examined. Cognitive resource depletion was manipulated by having
participants solve either difficult or easy anagrams. A “Shooter Task” measuring unintended racial discriminatory behavior followed. participants
then reported their subjective experiences in the task. Finally, ImCp and
an implicit race-weapons stereotype were measured, both using Go/no-go
Association Tasks (GnATs). ImCp moderated the effect of depletion on discriminatory behavior: depletion resulted in more racial bias in the Shooter
Task only for those who scored low in our measure of ImCp, while high
ImCp participants performed comparably in both the low and high depletion conditions.

In the spring of 1957, the Center for Studies in Higher Education (CSHE) at the University of California, Berkeley was formally established as an organized research unit, enabled by an initial grant from the Carnegie Corporation and making it the first academic enterprise in the United States focused on higher education policy issues. Since then, the Center has been an important source for encouraging an international comparative perspective, and this thereby provided a timely scholarly theme for reflecting and projecting the role of higher education in society within a globalizing world.

Racial segregation is often blamed for some of the achievement gap between blacks and whites. We study the effects of school and neighborhood segregation on the relative SAT scores of black students across different metropolitan areas, using large microdata samples for the 1998–2001 test cohorts. Our models include detailed controls for the family background of individual test-takers, school-level controls for selective participation in the test, and city-level controls for racial composition, income, and region. We find robust evidence that the black–white test score gap is higher in more segregated cities. Holding constant family background and other factors, a shift from a highly segregated city to a nearly integrated city closes about one-quarter of the raw black–white gap in SAT scores. Specifications that distinguish between school and neighborhood segregation suggest that neighborhood segregation has a consistently negative impact while school segregation has no independent effect, though we cannot reject equality of the two effects. Additional tests indicate that much of the effect of neighborhood segregation operates through neighbors' incomes, not through race per se. Data on enrollment in honors courses suggest that within-school segregation increases when schools are more highly integrated, potentially offsetting the benefits of school desegregation and accounting for our findings.

National systems of public higher education are in a state of flux. Throughout the world, a shift is occurring in the support and perception of the purpose of public research universities. Many national governments are attempting to bend their higher education systems to meet their perceived long-term socio-economic needs. At the same time, there are relatively new supranational influences on higher education markets and practices that will grow in influence over time, including the Bologna Agreement, the European Commission, the pending General Agreement on Trade and Services, and globalization associated with broadband communication and internationalization of corporations.
