Amend the old or address the new: Broad-based legislation when proposing policies is costly

If each legislator wishes to encourage other legislators to address new problems in future periods, then a subgame perfect Nash equilibrium can exist with the following properties: (1) no legislator finds it worthwhile to make a narrow proposal that appeals to a minimum majority; (2) instead, legislators propose policies that appeal to all members, not for fear of retaliation, but rather to encourage other members to work on new problems in succeeding periods; (3) in succeeding periods no legislator amends the existing broad policy. We find an equilibrium with these properties in finite as well as infinite period games.     

Neighborhoods of last resort: How landlord strategies concentrate violent crime

Studies of crime hot spots have argued that landlords’ management styles, specifically their tenant screening and property monitoring techniques, affect crime. These studies, however, have rarely considered the political–economic contexts in which these actions take place: specifically, how landlords’ behaviors are shaped by, and themselves reproduce, larger rental market structures. Drawing on data pertaining to eviction rates, criminal incidents, housing code violations, and landlord behavior in Milwaukee, Wisconsin, this study documents how extractive rental management strategies, such as weak tenant screening, frequent eviction filings, and property disinvestment, concentrate crime at particular properties. In turn, high rates of crime in a neighborhood incentivize these extractive landlord strategies. By showing how landlords’ economic strategies are central to urban crime geographies, this study contributes to our understanding of third-party policing by revealing the limits of market-based solutions to place management dilemmas.     

Preclinical Assessment of Safety and Efficacy of Fluorescent Dye for Detecting Dermal Injuries (the injuries were both abrasions and incision) in a Murine Model

Objective documentation of tears and abrasions to the external genitalia after sexual assault is an important part of the forensic examination. A 1% aqueous solution of toluidine blue (TB) dye is often used to highlight injury, but the dye can be difficult to see on dark skin. We evaluated a fluorescent dye for detecting injuries on all skin colors in a relevant preclinical murine model. We compared the ability of trained, blinded observers to detect unstained wounds and wounds stained with 1% fluorescein sodium (FL) and with TB. We also evaluated the cutaneous wound healing response after application of both dyes. The no‐dye group had significantly fewer (p < 0.05) true‐positive identifications compared to all the dye groups. No differences in effectiveness were detected between dye treatments. All groups exhibited statistically similar healing rates. These findings support the evaluation of fluorescein sodium in a future clinical study with human subjects.     

Law Enforcement and the Rights of the Accused: Are the Police Getting a Bad Rap?

Nationwide, law enforcement professionals have endured increasing scrutiny regarding their treatment of custodial suspects and their alleged abridgement of suspects’ Constitutional rights. At the same time, in the interests of community safety, many members of the public fully expect police officers to function efficiently in arresting and facilitating the prosecution of likely perpetrators. These perspectives reflect due-process and crime-control models respectively. Very little is known, however, about how law enforcement professionals actually view the rights of the accused when not acutely immersed in the cross-currents of public opinion. Using an anonymous survey, the current investigation addresses both Miranda rights as well as the European Union’s (EU) much more comprehensive approach to the rights of the accused. In general, this sample of 209 urban police officers favored protections of criminal suspects that went considerably beyond Miranda safeguards.
