Sometimes What Everybody Thinks They Know Is True

This essay responds to D. Davis and W. C. Follette (2002), who question the value of motive evidence in murder cases. They argue that the evidence that a husband had extramarital affairs, that he heavily insured his wife's life, or that he battered his wife is ordinarily of infinitesimal probative value. We disagree. To be sure, it would be foolish to predict solely on the basis of such evidence that a husband will murder his wife. However, when this kind of evidence is combined with other evidence in a realistic murder case, the evidence can be quite probative. We analyze cases in which it is virtually certain that the victim was murdered but unclear who murdered her, and in which it is uncertain whether the husband murdered the wife or she died by accident. We show that in each case motive evidence, such as a history of battering or of infidelity, can substantially increase the odds of the husband's guilt. We also consider the actual case on which Davis and Follette base their paper. We argue that testimony of Davis on the basis of the analysis presented in their paper was properly excluded, for it would have been misleading and unhelpful.     

The Effect of Safety Net Generosity on Maternal Mental Health and Risky Health Behaviors

Single mothers are more likely to experience mental health problems and stress-related negative health behaviors than their married counterparts, but a more generous safety net may improve these outcomes. We use a simulated safety net eligibility approach that accounts for interactions across safety net programs and relies on changing policies across states and time to identify causal effects of safety net generosity on psychological distress and risky behaviors of single mothers. Results suggest that a more generous safety net is protective of maternal mental health: a $1,000 increase to the simulated potential combined cash and food benefit package reduces severe psychological distress by 8.4 percent. Breaking out effects by individual programs while still controlling for potential benefits from other programs, we find protective effects of tax credits, cash benefits provided by Temporary Assistance for Needy Families, and food benefits provided by Supplemental Nutritional Assistance, but no effects of Medicaid eligibility. The effects are primarily driven by single mothers with the lowest levels of education. We find no significant effects of generosity on daily smoking, but we find evidence that benefits reduce the likelihood of heavy drinking. Results suggest that government investments in resources available to low-income families can be effective at improving well-being.     

Understanding Multilevel Governance Processes through Complexity Theory: An Empirical Case Study of the Quebec Health-Care System

This paper aims to contribute to a better understanding of multilevel governance processes. We do so by focusing on the in-depth examination of the institutional changes recently implemented in the Quebec health care delivery system that require a close collaboration between interdependent actors acting at various levels of governance. Our three research questions are: (1) How does multi-level governance emerge in a pluralist institutuional context? (2) How do multi-level governance processes shape the adaptive capacity of the organization to its environment? (3) How does institutional context influence these multi-governance processes?Our empirical investigation is inspired by the theory of complexity which invites us to pay attention to three processes: self-organization, eco-self organization and co-evolution. This study shows that the effectiveness of multi-level governance processes do not only go through the implementation of instruments aiming at aligning the action of lower government levels with the objectives of the upper levels as suggested by numerous existing works. More precisely, it suggests that more distributed and coordinated processes favor a more homogenous form of adaptation (Miller and Page, 2007) taking into account the interdependence between stakeholders.     

Comparison of the M-Vac® Wet-Vacuum-Based Collection Method to a Wet-Swabbing Method for DNA Recovery on Diluted Bloodstained Substrates*†‡

A wet-vacuum-based collection method with the M-Vac^® was compared to a wet-swabbing collection method by examining the recovery of diluted blood on 22 substrates of varying porosity. The wet-vacuum method yielded more total nuclear DNA than wet-swabbing on 18 porous substrates, recovering on average 12 times more DNA. However, both methods yielded comparable amounts of total DNA on two porous and two nonporous substrates. In no instance did wet-swabbing significantly recover more DNA. The wet-vacuum method also successfully collected additional DNA on previously swabbed substrates. Mitochondrial DNA yields were assessed, and outcomes were generally similar to the nuclear DNA outcomes described above. Results demonstrate that wet-vacuuming may serve as an alternative collection method to swabbing on difficult porous substrates and could potentially recover additional DNA on previously swabbed substrates. However, swabbing remains the preferred collection method on substrates with visible stains and/or nonporous surfaces for reasons of convenience, simplicity, and lower cost relative to the wet-vacuum method.     

Sovereignty in the Balance: Claims and Bargains at the UN Conferences on the Environment, Human Rights, and Women

States vary the content and subject matter of their claims to sovereignty. In an analysis of when states invoked sovereignty at recent UN World Conferences on the environment (1992), human rights (1993), and women (1995), the authors revise and extend Litfin's (1997) notion of bargains among components of sovereignty. At the conferences, states invoked sovereignty in debates over cultural and religious values, economics, and increased international accountability. The authors interpret the debates based on how four elements of sovereignty—autonomy, control, and legitimacy in the eyes of other states and nonstate actors—are traded by states through implicit or explicit bargaining. They identify patterns that vary by issue area. The authors argue that nongovernmental organizations as well as other states may legitimate or delegitimate states' sovereign claims. They find that countries of the global South made more sovereignty claims of all kinds than Northern states. And, sovereignty bargains may be struck more easily over power and economics than social values.     

Putting Ourselves in Another’s Skin: Using the Plasticity of Self-Perception to Enhance Empathy and Decrease Prejudice

The self is one the most important concepts in social cognition and plays a crucial role in determining questions such as which social groups we view ourselves as belonging to and how we relate to others. In the past decade, the self has also become an important topic within cognitive neuroscience with an explosion in the number of studies seeking to understand how different aspects of the self are represented within the brain. In this paper, we first outline the recent research on the neurocognitive basis of the self and highlight a key distinction between two forms of self-representation. The first is the “bodily” self, which is thought to be the basis of subjective experience and is grounded in the processing of sensorimotor signals. The second is the “conceptual” self, which develops through our interactions of other and is formed of a rich network of associative and semantic information. We then investigate how both the bodily and conceptual self are related to social cognition with an emphasis on how self-representations are involved in the processing and creation of prejudice. We then highlight new research demonstrating that the bodily and conceptual self are both malleable and that this malleability can be harnessed in order to achieve a reduction in social prejudice. In particular, we will outline strong evidence that modulating people’s perceptions of the bodily self can lead to changes in attitudes at the conceptual level. We will highlight a series of studies demonstrating that social attitudes towards various social out-groups (e.g. racial groups) can lead to a reduction in prejudice towards that group. Finally, we seek to place these findings in a broader social context by considering how innovations in virtual reality technology can allow experiences of taking on another’s identity are likely to become both more commonplace and more convincing in the future and the various opportunities and risks associated with using such technology to reduce prejudice.
