Protective behavioral strategies (PBS) are useful skills for reducing the negative consequences of alcohol. The moderating effects of anxiety on the relationship between 3 different types of PBS and negative consequences were examined among students accessing college counseling services. Results revealed a significant interaction between anxiety and strategies while drinking, suggesting that these simple strategies may be particularly beneficial among students who drink heavily and experience high levels of anxiety. Implications for counseling centers are discussed. 相似文献

Criminal justice programs at traditional institutions of higher learning have been moving toward offering courses online and, in some cases, placing entire programs online for the better part of the past decade. In competition with for‐profit institutions, many traditional colleges and universities have expanded their distance education programming to include online courses and programs to attract students. As a result, the number of criminal justice students has increased, as have the profits for home institutions. With this growth in the online education market, the criminal justice faculty member has been thrust, willingly or unwillingly, into the world of online teaching—a method of instruction foreign to many instructors. From the authors’ experience at their current (and in the case of the lead author a second) institution, this paper addresses many issues that must be considered by faculty members before embarking on this type of time‐intensive initiative. 相似文献

Effects of a combined inversion and plantarflexion surface on knee and hip kinematics during landing

Although landing in a plantarflexion and inversion position is a well-known characteristic of lateral ankle sprains, the associated kinematics of the knee and hip is largely unknown. Therefore, the purpose of this study was to examine the changes in knee and hip kinematics during landings on an altered landing surface of combined plantarflexion and inversion. Participants performed five drop landings from 30 cm onto a trapdoor platform in three different conditions: flat landing surface, 25° inversion, or a combined 25° plantarflexion and 25° inversion. Kinematic data were collected using a seven camera motion capture system. A 2 × 3 (leg × surface) repeated measures ANOVA was used for statistical analysis. The combined surface showed decreased knee and hip flexion range of motion (ROM) and increased knee abduction ROM (p < 0.05). The altered landing surface creates a stiff landing pattern where reductions in sagittal plane motion are transferred to the frontal plane, resulting in increased knee abduction. A stiff landing pattern is frequently related to increased risk of anterior cruciate ligament injury. It may be beneficial for athletes at risk to train for alternate methods of increasing their sagittal plane motion of the knee and hip with active knee or trunk flexion. 相似文献
