Independent social choice correspondences

A fixed agenda social choice correspondence on outcome set X maps each profile of individual preferences into a nonempty subset of X. If satisfies an analogue of Arrow's independence of irrelevant alternatives condition, then either the range of contains exactly two alternatives, or else there is at most one individual whose preferences have any bearing on . This is the case even if is not defined for any proper subset of X.     

Risk as Analysis and Risk as Feelings: Some Thoughts about Affect, Reason, Risk, and Rationality

Modern theories in cognitive psychology and neuroscience indicate that there are two fundamental ways in which human beings comprehend risk. The “analytic system” uses algorithms and normative rules, such as probability calculus, formal logic, and risk assessment. It is relatively slow, effortful, and requires conscious control. The “experiential system” is intuitive, fast, mostly automatic, and not very accessible to conscious awareness. The experiential system enabled human beings to survive during their long period of evolution and remains today the most natural and most common way to respond to risk. It relies on images and associations, linked by experience to emotion and affect (a feeling that something is good or bad). This system represents risk as a feeling that tells us whether it is safe to walk down this dark street or drink this strange‐smelling water. Proponents of formal risk analysis tend to view affective responses to risk as irrational. Current wisdom disputes this view. The rational and the experiential systems operate in parallel and each seems to depend on the other for guidance. Studies have demonstrated that analytic reasoning cannot be effective unless it is guided by emotion and affect. Rational decision making requires proper integration of both modes of thought. Both systems have their advantages, biases, and limitations. Now that we are beginning to understand the complex interplay between emotion and reason that is essential to rational behavior, the challenge before us is to think creatively about what this means for managing risk. On the one hand, how do we apply reason to temper the strong emotions engendered by some risk events? On the other hand, how do we infuse needed “doses of feeling” into circumstances where lack of experience may otherwise leave us too “coldly rational”? This article addresses these important questions.     

Building Strategic Technology Alliances for Teaching and Learning

There is a major need for higher education to confront intense competition, enhance academic programs to meet the challenges of this competition, and to develop new teaching and learning strategies to meet the demands of the global marketplace. Technology and the Internet are intended to break down the barriers of time and space and enable more students to participate and collaborate with faculty and other students. Critical thresholds must be met in order to use technology to communicate, collaborate, and transform teaching and learning. Strategic technology alliances establish a partnership between technology vendors and higher education that will achieve these thresholds to meet the teaching and learning needs of the 21st century student.

PATTERNS OF CONCEPTION, NATALITY, AND MORTALITY FROM MIDWESTERN CEMETERIES:

Our research demonstrates the potential of cemeteries data for sociology and contributes to a greater understanding of demographic and social patterns characterizing the Midwest since its Euramerican settlement. We examine data from ten cemeteries (2,021 burials) spanning the 1830s–1980s in east-central Illinois. Seasonal conception patterns reflect winter and spring peaks, with indication of the spring peak dissipating more recently. Seasonal mortality patterns show a tendency for younger people to die in late summer and older people to die in late winter. Contrary to national patterns, we found female deaths exceeding male deaths in the 10–64 age group. As expressions of gender bias, females are disproportionately identified on gravestones in terms of familial relationships. Of the different cemetery types surveyed (1 family, 4 neighborhood, 2 community, 3 church), only the church cemeteries continue to be used, suggesting a sectarian role in preserving otherwise declining communities.     

Public confidence in the U.S. Supreme Court: A new look at the impact of Court decisions

Judicial scholars have long debated the notion that Court decisions can influence the public's attitudes toward the U.S. Supreme Court. We engage this literature by introducing new dimensions to existing theory for predicting the impact of Court decisions on public confidence in the Court and by introducing innovative methods to test our hypotheses. We begin our analysis by examining the relationship between specific Court decisions and public confidence with aggregate time series data. Our analysis then shifts to an examination of individual-level survey data to examine the same hypotheses. Our results indicate that specific decisions can have a significant positive and negative impact on individual-level confidence in the Court. We conclude with a discussion of the implications of our findings for the theoretical and methodological debates over the influence of Court decisions on public confidence.
