Trigger pull is the force that needs to be exerted on the trigger to discharge a firearm. The measurement of trigger pull can assist in the evaluation of the safety, function, and manufacturing characteristics associated with a firearm during the forensic firearm examination process. Nonetheless, the accuracy and uncertainty of trigger pull measurements may be affected by the measuring device, test procedure, and environmental conditions. In this work, an innovative finger-trigger interface device was developed to facilitate accurate trigger pull measurements. The idea was to reduce the variation related to the position of the measurement device on the trigger in existing measuring methods and devices. Three force sensors based on different technologies were initially evaluated. While two of the three sensors failed to produce data, the miniature capacitive plate sensor exhibited high precision and a linear response over the range of typical trigger pulls. To examine the effects of the finger-trigger interface on trigger pull measurement, different sensor housing prototypes were designed in silico and 3D printed for the construction of three finger-trigger interface devices. The performance of each finger-trigger interface device was evaluated by measuring the trigger pulls of several selected firearms and comparing the data to a previously published study. Our preliminary results demonstrated the novel finger-trigger interface device offered a new way to measure trigger pull in situ with acceptable accuracy and precision.  相似文献

I review arguments favoring bans on problematic speech (e.g., hate speech) on campus. Contrasting such calls for top-down regulation, I explore the potential for a “bottom-up approach” to campus speech governance to address vexing concerns pertaining to campus speech without violating free speech and academic freedom principles. I examine the political economy and epistemological dynamics inherent within the two forms of governance. I argue that, relative to a centralized top-down approach, a decentralized bottom-up approach to speech governance avoids political dynamics that bend toward the inappropriate use of power. Further, I argue that a bottom-up approach leaves the discursive space contestable, and therefore more open to new discovery and correction. Recognizing that a bottom up approach is no panacea, I also consider open questions and concerns that warrant further inquiry.  相似文献

An analysis of communication disaster response in four well‐known natural disasters explores at what stage a disaster communication plan can fail. Based on a marketing strategy formulation–implementation framework, four different outcomes are used to examine what makes a disaster communication plan succeed or fail. This leads to an identification of barriers to the implementation of disaster communication plans. Very often in disaster communication plan failures the strategy formulation is blamed. However, often it is implementation at fault. This makes it hard to diagnose the reason for the communication plan failure. By taking heed of the barriers identified here, disaster response executives can hopefully overcome some of the causes of disaster communication plan failure. Avenues for future research are identified.  相似文献

Growth curve analyses were used to investigate parents’ and peers’ influence on adolescents’ choice to abstain from antisocial behavior in a community-based sample of 416 early adolescents living in the Southeastern United States. Participants were primarily European American (91%) and 51% were girls. Both parents and peers were important influences on the choice to abstain from antisocial behavior. Over the four-year period adolescents relied increasingly on parents as influences and relied less on peers as influences to deter antisocial behavior. Significant gender differences emerged and suggested that female adolescents relied more on social influences than did male adolescents but that as time progressed male adolescents increased the rate at which they relied on peers. Higher family income was associated with choosing peers as a social influence at wave 1, but no other significant income associations were found. Understanding influences on adolescents’ abstinence choices is important for preventing antisocial behavior.

ABSTRACT

On 24 August 2012, the Honourable Maria Lourdes Sereno was appointed Chief Justice of the Philippine Supreme Court, the first woman to hold such position since its establishment in 1901. Several cases involving important women’s issues decided during her term were reviewed in this work, inspired by the possibility that a young, brilliant and hardworking woman of humble beginnings sitting at the helm could make a difference. Indeed, the Chief Justice manifested commendable grit in registering meaningful dissent in Imbong v. Ochoa, where she championed women’s bodily autonomy, and when she wrote a provocative concurrence in Vinuya v. Romulo, where she gave hope to women who suffered wartime atrocities. However, she missed an opportunity to put the rape shield law into good use in deciding People v. Batuhan and Lacturan. Her concurrence was also disappointing in Garcia v. Drilon, where she favoured rational basis review over intermediate level of scrutiny for gender-based classification, in People v. Jumawan where a conviction for marital rape was based on romantic paternalism, in People v. Palotes where additional compensatory damages were not considered for a rape victim who bore a child, in People v. Tionloc where acquittal was based on rape myths, and in People v. Caoili where the Court refused to call rape by its ugly name.  相似文献
