Differential Effects of Formal and Informal Gambling on Symptoms of Problem Gambling During Voluntary Self-Exclusion.

Voluntary self-exclusion (VSE) programs enable problem gamblers to engage in a break from casino-based gambling. The current study analyzed the effects of a VSE program in British Columbia, Canada on problem gambling symptoms and the comparative reductions in problem gambling symptoms when participants abstained from gambling, continued to participate in non-casino based gambling, or attempted to violate their exclusion contract. 269 participants completed two telephone interviews over a 6-month period. Participants were administered the Problem Gambling Severity Index (PGSI). Substantial reductions in PGSI scores were observed after 6 months. Program violators had significantly smaller PGSI Difference Scores by Time 2 compared to those who continued to gamble outside of the casino and those who completely abstained from all gambling. There were no significant differences between those who gambled informally and those who abstained. A multiple regression identified that while access to counselling and length of enrollment also contributed to the reduction in PGSI scores, violation attempts were most strongly associated with smaller reductions in symptoms of problem gambling. These results imply that some gamblers can successfully engage in non-casino based forms of gambling and still experience reductions in symptoms of problem gambling. Future analyses will explore characteristics associated with group membership that may help to identify which participants can successfully engage in non-casino based gambling without re-triggering symptoms of problem gambling.

The Temporal (In)Stability of the Unemployment and Crime Relationship.

The complex relationship between crime and economic change has had a long pedigree in criminological research. This article considers the temporal stability of the Cantor and Land model of unemployment and crime using a decomposition model of Canadian provinces, 1981 to 2009. We include multiple economic measures for a more comprehensive representation of economic performance, allowing for the estimates of long- and short-run unemployment effects to vary over time. We undertake this analysis considering 12 crime types, finding strong support for the Cantor and Land model in both property and violent crimes. However, in a number of cases, we find that there is significant variation of these relationships over time. This result implies that support for this model depends on the time period analyzed and that any policy derived from this model of unemployment and crime is time-period dependent.

An Empirical Examination of the Victim-Search Methods Utilized by Serial Stranger Sexual Offenders: A Classification Approach.

Past research on the spatial mobility of serial offenders has generally found that these individuals make calculated decisions about the ways in which they come into contact with suitable victims. Within the geographic profiling literature, four victim-search methods have been theorized that describe how serial predatory offenders hunt for their victims: hunter, poacher, troller, and trapper. Using latent class analysis, the aim of this study is to test whether this theoretical typology can be empirically derived using data that were collected from both police files and semi-structured interviews with 72 serial sex offenders who committed 361 stranger sexual assaults. Empirical support is found for each of the aforementioned victim-search methods, in addition to two others: indiscriminate opportunist and walking prowler. Chi-square analyses are also conducted to test for associations between this typology and characteristics of the offense such as victim information, environmental factors, and the offender's modus operandi strategies. Findings from these analyses suggest that the types of victims and environments targeted by the offender, as well as the behaviors that take place both before and during the offense, are dependent upon the offender's victim-search strategy. Although the theoretical hunter, poacher, troller, and trapper were intended to describe the victim-search methods of serial violent predators more generally, the finding that these strategies exist along with two others in this sample of sexual offenders may indicate that search behavior is specific to certain crime types. Furthermore, these findings may be of assistance in the investigation of stranger sexual assaults by providing law-enforcement officials with possible clues as to the characteristics of the unknown suspect, the times and places likely targeted in any past or future events, and possibly even his base of operations.
