ABSTRACT To clarify environmental predictors of bar-room aggression by differentiating relationships due to nightly variations versus across bar variations, frequency versus severity of aggression and patron versus staff aggression.
Male-female pairs of researcher-observers conducted 1334 observations in 118 large capacity (> 300) bars and clubs in Toronto, Canada.
Observers independently rated aspects of the environment (e.g. crowding) at every visit and wrote detailed narratives of each incident of aggression that occurred. Measures of severity of aggression for the visit were calculated by aggregating ratings for each person in aggressive incidents.
Although bivariate analyses confirmed the significance of most environmental predictors of aggression identified in previous research, multivariate analyses identified the following key visit-level predictors (controlling for bar-level relationships): rowdiness/permissive environment and people hanging around after closing predicted both frequency and severity of aggression; sexual activity, contact and competition and people with two or more drinks at closing predicted frequency but not severity of aggression; lack of staff monitoring predicted more severe patron aggression, while having more and better coordinated staff predicted more severe staff aggression. Intoxication of patrons was significantly associated with more frequent and severe patron aggression at the bar level (but not at the visit level) in the multivariate analyses and negatively associated with severity of staff aggression at the visit level.
The results demonstrate clearly the importance of the immediate environment (not just the type of bar or characteristics of usual patrons) and the importance of specific environmental factors, including staff behaviour, in predicting both frequency and severity of aggression.

    • "Also, aggression on the dance floor may be related to crowding in that area, which suggests the need to improve the design and supervision of dance floors (Graham et al. 2012). The incidence of aggression in shady areas after closing time implies that an efficient closing procedure is also important as the number of people remaining in the venue is associated with the frequency of aggressive acts (Graham et al. 2006). Alternatively, improving the lighting in these areas may also be effective in reducing the incidence of aggression (Homel, Carvolth, Hauritz, McIlwain, & Teague, 2004). "

    ABSTRACT: Objectives: This article further examines the phenomenon of aggression inside barrooms by relying on the “bouncer-ethnographer” methodology. The objective is to investigate variations in aggression through time and space according to the role and routine of the target in a Montreal barroom. Thus, it provides an examination of routine activity theory at the micro level: the barroom. Methods: For a period of 258 nights of observation in a Canadian barroom, bouncers completed reports on each intervention and provided specific information regarding what happened, when and where within the venue. In addition, the bouncer-ethnographer compiled field observations and interviews with bar personnel in order to identify aggression hotspots and “rush hours” for three types of actors within barrooms: (a) bouncers, (b) barmaids and (c) patrons. Findings: Three different patterns emerged for shifting hotspots of aggression depending on the target. As the night progresses, aggressive incidents between patrons, towards barmaids and towards bouncers have specific hotspots and rush hours influenced by the specific routine of the target inside the barroom. Implications: The current findings enrich those of previous work by pointing to the relevance of not only examining the environmental characteristics of the barroom, but also the role of the target of aggression. Crime opportunities follow routine activities, even within a specific location on a micro level. Routine activity theory is thus relevant in this context, because as actors in differing roles follow differing routines, as do their patterns of victimization.

    • "Second, alcohol use and addiction may relate crimes to the need for resources to obtain additional alcohol (Rush et al. (1986) and Colon et al. (1982)). Third, the use of alcohol does not lead to crime, but rather creates an environment that encourages criminal behavior (Graham et al. (2006), Toomey and Wagenaar (2002) and Homel et al. (1992)). Most alcohol control policies 7 attempt to limit the positive relationship between alcohol use and crime by limiting alcohol availability. "

    ABSTRACT: With the end of National Prohibition in 1933, thirty states gave counties and municipalities the local option to continue alcohol restrictions. Currently, 10% of U.S. counties still maintain a ban on some or all alcohol sales. Since the Prohibition movement advanced on the association between alcohol use and criminal behavior, this research examines the impact of county level alcohol restrictions on multiple types of crime across five U.S. states. Standard panel models find a positive relationship between local option policy changes to allow alcohol and crime. The novelty of this research involves comparing the impact of alcohol restrictions on crimes often committed under the influence of alcohol versus crimes commonly committed without the use of alcohol. A difference-in-difference-in-difference estimator shows that increasing access to alcohol has no impact on crime types often committed under the influence of alcohol.

    • "Such fi ndings are consistent across a range of populations, including prison inmates (Phillips et al., 2007) and adolescents (Wells et al., 2006). Barroom observations reveal that degree of alcohol intoxication is strongly associated with more severe aggression (Graham et al., 2006a, 2006b), and similar fi ndings are observed in general population studies (Wells and Graham, 2003; Wells et al., 2000). One such investigation found that aggressive incidents could be predicted by the number of drinks consumed 6 hours earlier (Wells and Graham, 2003). "

    ABSTRACT: Numerous studies have examined the impact of alcohol on violence; however, only a small number have addressed differences elicited by different doses of alcohol. Such studies are limited by mixed findings, small sample sizes, inconsistent alcohol doses and control conditions, a bias toward studying only male participants, and the predominant use of only one particular measure to assess aggression. The present laboratory investigation was designed to elucidate and advance this literature by improving on these limitations. Participants were 187 (95 men and 92 women) social drinkers. Following the consumption of one of six alcohol doses (i.e., 0.0 g/kg, 0.125 g/kg, 0.25 g/kg, 0.5 g/kg, 0.75 g/kg, and 1.0 g/kg), participants were tested on a laboratory task in which electric shocks were received from and administered to a fictitious opponent under the guise of a competitive reaction-time task. Aggression was operationalized as the intensity and duration of shocks administered to one's "opponent." Analyses revealed a highly significant positive linear trend between alcohol dose and aggression for both genders. Our data aid in clarifying a body of literature that has been afflicted with numerous limitations and will help guide the selection of alcohol doses for researchers conducting future laboratory-based aggression studies.
