Adductor injuries account for the majority of acute groin injuries. Iliopsoas and proximal rectus femoris injuries are also common. More than 1 in 5 injuries showed no imaging signs of an acute injury. Clinically diagnosed adductor injuries were often confirmed on imaging, whereas iliopsoas and rectus femoris injuries showed a different radiological injury location in more than one-third of the cases. The discrepancy between clinical and radiological findings should be considered when diagnosing acute groin injuries.

This paper reports findings from an exploratory, place specific study of the relationship between victims' lifestyles, routine activities, and residential burglary victimization. A telephone survey differentiated people with various lifestyles in terms of daily obligatory and discretionary activities. These differential lifestyles were related to variations in routine activities (i.e., pedestrian and automotive traffic) on street segments around residential areas. In a pooled cross-sectional design, street segments with higher volumes of routine activities between 1992-1996 had significantly lower burglary rates over this time period, as did street blocks with irregular periods of routine activities in 1997. Implications are discussed for the lifestyle I exposure and routine activity theories and for the movement in criminology away from explaining why individual offenders commit crimes, toward explaining why crimes happen at particular places at particular times and not others.

tae Choo, sunghoon roh, Matthew robInsonThe current study examines the applicability of the "gateway hypothesis" to drug use patterns of secondary school students from a nonmetropolitan area in Tennessee. The data were collected from students in the 8 th , 10 th , and 12 th grades at three secondary schools, using self-administered questionnaires under supervision of teachers. Although there is some support for the gateway hypothesis in our data, there is also evidence that what differentiates those who move from initial marijuana use to use of harder drugs are risk factors unique to individuals and their environments, consistent with the predictions of problem behavior theory and integrated systems theory. Implications for various interpretations of the gateway hypothesis are discussed.

This study identified environmental characteristics associated with residential burglaries of apartment complexes predominantly occupied by students, located near two major universities and a community college in Tallahassee, Florida. Through observation and measurement of environmental characteristics, results showed that accessibility played little role in differentiating burglarized and nonburglarized apartment units. Yet, burglarized units were disproportionately likely to be located on the corner of the building and on the first floor. Results also showed that apartment units with reported burglaries in 1993 were less surveillable than apartment units with no reported burglaries--i.e., burglarized units were more obstructed by foliage or structure. Finally, through surveying student apartment residents, results suggested that burglaries largely occurred at times when students reported being away from their apartments for purposes of attending classes, engaging in recreational activities, or shopping. The results add additional support for the well-established link between environmental characteristics and residential burglary. ARTICLEOver the past several decades, there has been a growing body of theoretical and research literature dealing with environmental factors associated with burglary. This literature seldom has given specific attention to apartment complexes, and studies focusing on privately owned and operated complexes predominantly occupied by college and university students are conspicuous by their absence.
