Exploring Online Sexually Explicit Material: What is the Relationship to Sexual Coercion?

With the popularity of the Internet, it is easy to access sexually explicit material. Past research has demonstrated that exposure to sexually explicit material in traditional formats (i.e. magazines and videos) may have an influence on male attitudes and behaviors towards females, but these effects appear to be minimal and dissipate over the long term. Though the body of literature examining Internet sexually explicit material is smaller, researchers have found little to no effects on attitudes or aggressive behaviors immediately after exposure. However, research regarding exposure to online sexually explicit material has not included forensically relevant variables. Previous research has suggested that undergraduate males who report engaging in sexually coercive or aggressive behaviors differ in terms of personality, attitudinal, and behavioral variables from individuals who do not report this type of behavior. Therefore, the purpose of this study was to examine the same personality and attitudinal variables that have been studied in previous research, but to extend this research by including behavioral variables related to the viewing of online sexually explicit material. Male undergraduate students were provided with a link to take an online survey examining personality (empathy, sensation-seeking, and psychopathy), attitudinal (rape myth belief, acceptance of interpersonal violence, and hostility towards women) and behavioral (online sexual compulsivity and online behaviors with regard to sexual material) variables. The relationship between these variables and sexually coercive behavior was examined. Results indicate there is a significant relationship between some scales related to empathy and viewing sexually explicit or degrading material. Further results indicated that individuals who identified as having engaged in sexually aggressive behavior endorsed more items related to online sexually compulsive behaviors. Exploratory analyses revealed that the amount, as opposed to the type, of sexually explicit material viewed appears to be more related to adverse outcomes.

Risk-based Modeling to Develop Zoning Criteria for Land-use Near Canadian Airports

Land development in the vicinity of airports often leads to land-use that can attract birds that are hazardous to aviation operations. For this reason, certain forms of land-use have traditionally been discouraged within prescribed distances of Canadian airports. However, this often leads to an unrealistic prohibition of land-use in the vicinity of airports located in urban settings. Furthermore, it is often unclear that the desired safety goals have been achieved. This paper describes a model that was created to assist in the development of zoning regulations for a future airport site in Canada. The framework links land-use to bird-related safety-risks and aircraft operations by categorizing the predictable relationships between: (i) different land uses found in urbanized and urbanizing settings near airports; (ii) bird species; and (iii) the different safety-risks to aircraft during various phases of flight. The latter is assessed relative to the runway approach and departure paths. Bird species are ranked to reflect the potential severity of an impact with an aircraft (using bird weight, flocking characteristics, and flight behaviours). These criteria are then employed to chart bird-related safety-risks relative to runway reference points. Each form of land-use is categorized to reflect the degree to which it attracts hazardous bird species. From this information, hazard and risk matrices have been developed and applied to the future airport setting, thereby providing risk-based guidance on appropriate land-uses that range from prohibited to acceptable. The framework has subsequently been applied to an existing Canadian airport, and is currently being adapted for national application. The framework provides a risk-based and science-based approach that offers municipalities and property owner’s flexibility in managing the risks to aviation related to their land use.
