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

Determining the application sequence of hand-written pen ink and printer toner lines has attracted significant interest in questioned document examination. This study uses coaxial light to determine line-crossing sequences, with intersections observed under a VSC600 forensic document workstation and a Leica M205A Stereo-microscope. Results show that reflected light at intersections and color contrast between intersections and nonintersections was observed when a hand-written ink line passes over a toner line, while a toner line passing over a written line appeared dull, with no color contrast. The procedure was tested under a range of conditions, such as types of writing pens and laser printers, the writer, and writing pressure, with the latter playing an important role in the evaluation. To validate the results, a 90% detection rate and 98% accuracy rate were achieved from 50 samples of blind testing, which is more effective than optical microscopy.  相似文献

History has taught us that the Global North's attempts to ‘civilise' the rest of the world's population, both now and in colonial times, have been fraught with difficulty. This paper argues that this difficulty is mainly owing to the political standpoint and positioning of our perceived engineering and technical superiority. A failure to recognise this viewpoint and to change the way in which we work together—in a global sense—to solve issues such as climate change, threatens our ability to survive as a species. Political standpoints on such issues still assume a superiority of governments in the Global North. This paper retraces colonial engineering projects, mainly directed from the UK, that failed to consider the development of other populations in the world, and their needs. It is also posited that our exploitation in the Global North, which assumes historical superiority as a basic premise, will fail in tackling major issues. Change is needed through a decolonisation of engineering projects, and western engineering curricula that are used to train future professionals. Evidence of the impact of decolonisation on the engineering discipline itself is scarce, but nevertheless, a response is needed to ensure that a more inclusive curriculum and narrative is developed.  相似文献

The increased use of information and communication technologies (ICTs) has triggered enormous innovation in the public sector and created positive public value at the managerial, delivery of services, and policy levels. However, these positive outcomes do not automatically accrue simply by adoption of ICTs as public leaders can fail to adopt relevant new ICTs, use them poorly, or use them in ways that actually diminish public value, which raises the question of the importance of e-leadership. This article examines e-leadership and innovation capacity at the individual public manager level and fills in some gaps about the practice and implementation of ICTs in the public sector. We explore eight research questions useful in theorizing about e-leadership, develop constructs of e-leadership, and describe the current development of e-leadership. By comparing e-leadership in two country settings (South Korea and the United States), we also overcome the limitations of the existing Western-oriented studies about innovations in the public sector. In addition to the growth of e-leadership use and requirements for a variety of competencies equivalent to, but separate from, traditional communication competences, we find that national cultures exert significant influence on the major constructs of e-leadership, which implies that an effective e-leadership strategy should consider cultural contexts seriously.  相似文献

近年来台湾地区的刑事诉讼经历了重大的改革,其公诉权制约机制较为完善。对于检察官不起诉、缓起诉处分,立法设置了再议制、交付审判制进行监督和制约,防止检察官滥用不起诉权;对于检察机关的起诉则在审前以起诉审查制进行制约,防止未达起诉法定门槛的案件进入审判。对于大陆来说,其公诉权制约机制有很大的借鉴意义。大陆也应设立公诉权的司法权制约机制,对于检察机关的起诉和不起诉都应最终由法院来进行审查和制约,以保证公诉权合法行使。但对于台湾地区公诉权制约机制的不足之处,借鉴的同时需予以改进。  相似文献

Smart card technology is one of the most recent computer revolutions, making its way world-wide into the hands and wallets of everyone. Today smart cards are used all over the world as personal identification cards for corporate building security systems and personal computer equipment access control. Governments, financial services, transportation, telecommunications, healthcare, education, retail and many other industries are planning to or already using smart cards as a means of providing better security and improved services to its customers and users. Understanding the factors that influence user acceptance of information technology is of interest both to researchers in a variety of fields as well as procurers of technology for large organizations. The purpose of this study is to develop an acceptance model and evaluate the user acceptance of smart card in Iran. A pilot study is conducted and a total of 46 questionnaires were distributed among the master students in field of computer science (information security and software engineering) at University Technology Malaysia, Kuala Lumpur. The measurement items in the questionnaire asked about their awareness and acceptance of smart cards, and the initial findings are presented and discussed.  相似文献

This article discusses a theatrical spectacle created by Walt Disney and General Electric for the 1964 New York World’s Fair that has run for the last five decades: the Carousel of Progress, a history pageant that stages the evolution of domestic technology in the twentieth century. As a spectacle dedicated to celebrating tools that bolster women’s participation in the social reproduction of capitalism, the author argues, the Carousel shows how expos utilize theatricality in order to inscribe industrial technologies within corporate ideologies. By apprehending the Carousel of Progress as a site of corporate performance, the author demonstrates how the Carousel’s afterlife in theme park entertainment has enabled Disney to theatricalize disparate modes of capitalist futurity in response to shifting cultural sensibilities. The author situates the Carousel within an economy that has consistently presented female domestic labor as subordinate to corporate capital, culminating with its late-1990s staging of an illusory prefeminism, which fantasizes a twentieth century in which no feminist movement took place. Engaging with theories of corporate performance, this article takes up the Carousel of Progress’s production history as an indication of theatricality’s longstanding utility to corporate capitalism.  相似文献

The past decade has witnessed an intensifying focus on the development of irrigation in sub-Saharan Africa. It follows a 20-year hiatus in the wake of disappointing irrigation performance during the 1970s and 1980s. Persistent low productivity in African agriculture and vulnerability of African food supplies to increasing instability in international commodity markets are driving pan-African agricultural investment initiatives, such as the Comprehensive Africa Agricultural Development Programme (CAADP), that identify as a priority the improvement in reliability of water control for agriculture. The paper argues that, for such initiatives to be effective, there needs to be a re-appraisal of current dynamics of irrigation development in sub-Saharan Africa, particularly with respect to the role of small-scale producers’ initiatives in expanding irrigation. The paper reviews the principal forms such initiatives take and argues that official narratives and statistics on African irrigation often underestimate the extent of such activities. The paper identifies five key characteristics which, it argues, contradict widely held assumptions that inform irrigation policy in Africa. The paper concludes by offering a definition of ‘farmer-led irrigation’ that embraces a range of interaction between producers and commercial, government and non-government agencies, and identifies priority areas for research on the growth potential and impact of such interactions and strategies for their future development.  相似文献
