Sexual assault investigations present uniquely challenging circumstances to detectives, and a small proportion result in arrest. Improving sexual assault investigations requires expanding the evidence base to improve our understanding of how these investigations unfold and the factors associated with positive case outcomes, including the likelihood that an offender is arrested.

The authors abstracted data on 491 adult sexual assaults investigated by five large and midsized law enforcement agencies to describe the characteristics of sexual assault investigations and to explain the relationships between these characteristics and the likelihood that a suspect is arrested.

Overall, detectives move swiftly to investigate sexual assaults but tend to miss investigative opportunities that increase the likelihood of an arrest, like locating and processing the crime scene or pursuing interviews with key witnesses and leads. Sexual assaults typically lack physical evidence that can be used to identify and lead to an arrest of a suspected offender; when this evidence is present, the case is more likely to result in an arrest. Delayed reporting of the crime to law enforcement decreases the likelihood of a suspect being arrested, but the mechanisms are unclear.

Few studies have used a detailed data abstraction process for a large sample of cases from multiple law enforcement agencies to understand sexual assault investigations and their case outcomes. The results can improve practitioners' and researchers' understanding of sexual assault investigations, including those factors that increase the likelihood of a suspect's arrest.

Violence against the police represents an ongoing and serious problem in the USA. In 2014, over 48,000 law enforcement officers assaulted while on duty. Although over one in four of these resulted in injury, little is known about the conditions under which injury is likely to occur. The purpose of this paper is to provide an assessment of the individual and situational factors that predict injurious assaults against law enforcement.

Using logistic regression, the current study analyzes data from the 2012 National Incident-Based Reporting System (NIBRS) on all assaults against the police (n=8,987) in order to understand, within a routine activities theoretical framework, how individual-level characteristics (i.e. officer and offender characteristics) and situational influences (i.e. assignment type, activity type, and location) predict the likelihood that an assault will result in injury.

Overall, findings suggest support for a routine activities theory of violence against the police. Initiating an arrest, one-officer vehicle type, and incidents occurring on highways/roads were all more likely to result in injurious assaults against the police. Other predictors of injury include officer and offender demographics as well as the time the incident took place.

This research was unable to control for some factors that may influence the likelihood of injury such as wearing body armor. Additionally, NIBRS data are not nationally representative, which limits the generalizability of the findings.

This is one of the first papers to use national data to examine the individual and situational factors that predict injurious assaults against law enforcement.

Reviews previous research on the effects of CEO compensation structure, outlines the criteria for relative performance evaluation (RPE) and notes the paucity of empirical evidence to support it. Reports a study of the use of RPE for US bank CEO compensation 1976‐1988; and its relationship to shareholder, market and industry returns. Explains the methodology and presents the results, which suggest that CEO pay is positively linked to firm performance, but negatively linked to market/industry performance; and that performance is positively linked to CEO option wealth. Adds that both the pay/performance link and the use of RPE increased after bank deregulation in the early 1980s. Considers consistency with other research and concludes that the reduction in compensation risk offered by RPE should reduce compensation cost and thus provide a good reason for the banking industry to increase its use.
