The happy land homicides: 87 deaths due to smoke inhalation

We reviewed all 87 deaths from the Happy Land Social Club fire. All deaths were due to smoke inhalation. The carboxyhemoglobin (COHb) concentrations ranged from 37 to 93% with a mean of 76.5%. The vast majority (97%) of the decedents had a COHb concentration over 50%. Cyanide blood concentrations ranged from 0 to 5.5 mg/L with a mean of 2.2 mg/L. Nine decedents had no cyanide detected, and seven had cyanide concentrations of less than 1 mg/L. Fewer than one third of the decedents had thermal injuries, and most were partial thickness burns involving less than 20% body surface area. Ethanol was detected in 72% of decedents with a range of 0.01 to 0.29 g% and a mean blood concentration of 0.11 g%. Cocaine or cannabinoid use was identified in 9% of the decedents. All decedents were visually identified, and all had soot in the airway extending to the major bronchi. Carboxyhemoglobin concentrations corresponded well with deaths from smoke inhalation. Cyanide concentrations did not correspond with the extent of smoke inhalation, and the role of cyanide in contributing to these deaths is doubtful. Hydrogen chloride inhalation, as evidenced by comparison of the pH of tracheal mucosa to controls, was not a factor.     

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.     

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.     

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.     

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.     

How Close is Too Close?: The 2012 Election in the Electoral College

While it is too soon to predict the 2012 presidential winner, it is not too early to know that the general election is likely to be a fiercely competitive contest that will, assuming no major unexpected events occur (e.g., another recession), come down to a few thousand votes in a few swing states, most probably including Ohio. When a presidential election is this close, there exists the possibility that the popular vote winner and the electoral vote winner will differ, which has happened four times before (1824, 1876, 1888, and 2000), but continues to be controversial. More ominously, there is also a small, but real chance of an electoral vote tie between the candidates, which would then place the selection of the president in the House of Representatives and the vice president in the Senate. Even though congressional selection is the constitutionally prescribed remedy and has historical precedents (1800, 1824), it seems unlikely that the Electoral College would long survive what would surely be a spirited public debate over who should choose the president. Thus, the 2012 election results may be too close to sustain the legitimacy of the presidential selection method.
