射击教学效果的优劣与学员的心理活动紧密相联。在射击教学中,只有符合受教育者的心理和生理发展规律,才能使学员在受教育过程中充分感受到教育者的关心和信任,在学习过程中不断增强自信心,不断提高对射击的兴趣,从中挖掘出潜力,提高学员学习的主动性和自觉性,获得良好的教育效果。  相似文献

School shootings are not a new phenomenon in the United States or internationally. In comparison to other acts of violence experienced by youth, such tragedies are uncommon but garner extensive media attention. The Columbine High School shooting received more attention across a broader range of issues than any other school shooting, with only the Sandy Hook tragedy rivaling it for media attention. In the aftermath of the Columbine shooting, public sentiment regarding violence in schools became a central point of contention that bred fear and panic. Given the embeddedness of judges within the larger community context and the effects of community characteristics on sentencing outcomes, we wondered if the Columbine shooting – via moral panic and community upheaval – might have had an impact on judges imposing criminal sentences. To assess the effect of the Columbine shooting on judicial decision-making outcomes, the current study uses United States Sentencing Commission data from 1998 through 2001. In doing so, it contributes to the extant literature concerning the embeddedness of judges within communities and answers recent call for more research on the temporal context of sentencing disparities.  相似文献

School shooting tragedies and the juvenile justice system’s movement toward a retributive and punitive framework gravely impacted how primary and secondary school students, disproportionately urban districts, used security measures to lock down campuses and build “fortress-like” schools. This iteration of control on school campuses emerged in tandem with the most recent generation’s zero tolerance approach to student violence and problems; a policy widely regarded as ineffective in urban, suburban, and rural districts. As school shootings continue to impact state legislative action and public reactions to school management, this paper takes a critical approach to school security policies and reviews the evidence on the risk for school violence and how to move away from student control approaches that do not improve school safety. Instead, the incorporation of prosocial education and school engagement efforts finds that school and student safety is improved. These, and related approaches to student body management, decreases campus violence and may also minimize the risk of some school shootings - as rare as these tragic incidents are across the nation’s schools. The interplay of schools, students, and the juvenile and family courts is ongoing. Knowing how school districts can best approach their campus environments, safety, and learning is important for school social workers and court personnel because of how often these systems work, or do not work, together.  相似文献

The influence of muzzle instability on bullet deflection, when perforating laminated particleboards, was studied with three different handgun bullet types. The mean deflection angles of .32 Auto FMJ and .38 Special SJHP bullets were calculated to be 0.90° and 0.83°, respectively after perforating particleboards orthogonally at a 1 m muzzle-to-target distance. The mean angles dropped to 0.70° and 0.58° at a 15 m muzzle-to-target distance. The differences in deflection angles proved to be statistically significant (< 0.05) with p-values of 0.023 and 0.001, respectively. The mean calculated deflection angles of .38 Special LRN bullets also dropped from 1.51° to 1.38° when the muzzle-to-target distance was increased from 1 to 15 m, but this difference was not significant (p-value of 0.357). The results support the hypothesis that muzzle instability has an influence on deflection. The possible implications for shooting incident reconstructions and for future research are discussed.  相似文献

Measuring trajectory angles of bullet defects at a crime scene is an important part of crime scene investigation as these angles can be used for shooting incident reconstructions. The Washington State Patrol Crime Scene Response Team (WSP CSRT) had a desire to report and use measured trajectory angles. To report quantitative measurements, a statement of uncertainty for the measurement must also be reported due to an accreditation requirement through the ANSI National Accreditation Board (ANAB), through which the WSP CSRT is accredited. This evaluation examined the measurement uncertainty of the 3D laser scanning method that the WSP CSRT utilizes for measuring the vertical and azimuth angles from trajectory rods fitted to bullet defects. Three studies were performed which examined the variation of vertical and azimuth angle measurements from trajectory rods on flat surfaces, the variation of azimuth angle measurements from a trajectory rod on a curved surface, and a traceability study with known vertical and azimuth angle measurements. Seven common substrates were selected as target materials and were shot with 9 mm Luger and 0.45 Auto caliber bullets. A vehicle with one bullet defect was utilized for the curved surface study. The WSP's current fleet of Trimble X7 3D laser scanners, the WSP Criminal Investigation Division (CID) Detectives who operate these scanners, and the Forensic Scientists responsible for trajectory rod placement and angle measurements were utilized. An overall measurement uncertainty of +/− 2.6 degrees at an approximate 95% confidence interval was determined for all trajectory angles measured from trajectory rods.  相似文献

This study uses a media distortion analysis to examine the New York Times coverage of mass public shooting incidents occurring in the United States from 1966 to 2016. A comparison between media coverage and actual incidents is used to identify the characteristics influencing the newsworthiness of mass public shootings. This work expands the breadth and depth of media and mass public shooting research, strengthening the validity of previous findings, and identifying new characteristics influencing newsworthiness. Findings indicate significant predictors of newsworthiness include higher casualties and injuries, as well as perpetrators that are young, Middle Eastern, and ideologically motivated. School shootings are more likely to receive any coverage, and all non-workplace shootings receive salient levels of coverage. An incident is also more likely to receive any coverage if a combination of weapons is used. These findings have important implications for public knowledge and perceptions of mass public shootings.  相似文献

对射击教学训练,管理者通常只注意排除场所、设备等客观可见的危险点,而忽视了人的心理状态对安全具有决定性影响。因此,必须了解参与射击教学活动各类人员的心理状态及其对安全工作的影响,确保射击教学训练安全。  相似文献
