Development of a Novel Finger-Trigger Interface for Trigger Pull Measurement

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.     

盗窃罪中财产性利益占有的规范化解释进路

偷换二维码案的认定涉及诸多理论争议。通过对此类案件的构成要件定型分析可以发现,在涉事主体方面,行为人、商户、顾客三方关系是此类案件涉事主体的合理确定。无论是对于诈骗罪还是盗窃罪的行为定型方面,均存在难以解释的问题。特别是认为此类案件构成诈骗罪和新型三角诈骗的主张,在逻辑链条上无法有力地阐明其扩张解释的理由。对此,合理的解释路径是个别、例外地承认在此类涉及侵权行为以及民事请求权消灭的场合下,财产性利益的规范性占有的可能。这种规范化的理解虽然扩张了事实性的占有概念,但具有整体法秩序上的理由,并且符合刑法作为规范学的学科定位。与此同时,通过义务分配的功能性分析,也可以有效地区分不同情况,对于相关案件中的行为作出妥当的、符合罪刑法定原则要求以及司法实践需求的评价。     

Fatal Methemoglobinemia Due to Acute Inhalation of Methyl Nitrite in an Industrial Accident

Methyl nitrite is suggested to cause methemoglobinemia by generating methemoglobin, which may be lethal when the methemoglobin concentration exceeds 70%. However, intoxication with methyl nitrite is seldom reported compared with that with other nitrites. Here, we present an industrial accident involving methyl nitrite inhalation during its synthesis process that resulted in three fatalities and one survivor. The autopsy revealed conspicuous blue-gray discoloration in various parts of the body, including the skin, airway mucosa, vessels, brain, heart, and among other areas. The toxicological tests on the deceased showed methemoglobin concentrations in the blood over the lethal level and increased nitrite ion levels in the blood, gastric contents, liver, and lung tissue compared with those in control samples. The cause of death was determined to be methemoglobinemia-induced hypoxia due to methyl nitrite inhalation. This report provides evidence that in methyl nitrite intoxication, exposure duration has a significant influence on the postmortem changes and likelihood of a fatal outcome may be related to the age of the victim. More attention is required regarding the industrial hazards of this substance.

Corporate policy entrepreneurship and cross-boundary strategies: How a private corporation champions mobile healthcare payment innovation in China?

The private nature of corporate actors does not necessarily preclude them from contributing to public interest. When business strategies and genuine public motivation are favorably aligned, corporate actors from the private sector can also drive public sector innovations. For a private corporation, policy entrepreneurship inherently entails crossing not only the public–private boundary but also various policy domains. This study formulates five propositions to characterize the cross-boundary strategies of corporate policy entrepreneurship, a distinct form of policy entrepreneurship in a developing authoritarian state. The case study of mobile healthcare payment innovation in China finds that the corporate entrepreneur used a series of cross-boundary strategies adeptly that eventually made the innovation not only adopted in one locality but also rapidly diffused nationwide. These strategies were not used in isolation or in a pure stepwise fashion but appeared to be recursive and interactive, suggesting the dynamic nature of corporate policy entrepreneurship in a multilevel governance system. More studies could be done to further examine strategies and processes of other forms of policy entrepreneurship in various national and sectoral settings.     

Diffusion models over the life cycle of an innovation: A bottom-up and top-down synthesis approach

The diffusion models tend to be tested individually in isolation and remain the same over time for the studied innovations in the literature. Moreover, there is growing interest to learn from other countries in our current age of globalization. Therefore, this paper chooses the innovation of public resources trading platforms in China to fulfill above literature gaps. We have examined key events and the issuances of related laws and regulations by Chinese governments. Our contributions are twofold: (a) Our analysis and results show that the diffusion models evolve over the different stages of a life cycle of an innovation, contrasting to the literature results that diffusion models remain the same for their studied innovations. Due to major diverse characteristics among different adopter categories over a life cycle of an innovation, we argue that it is appropriate and necessary to apply different diffusion models on different adopter categories, which is missing in the current literature. (b) We find a first bottom-up and then top-down synthesis approach as an effective, efficient diffusion process for both fitting local needs (i.e., effective) and adopting innovations rapidly nationwide (i.e., efficient).     

论协商民主及其在我国的实现

作为一种在西方政治学界兴起的新理论,协商民主强调平等性、责任性和公共性.协商民主的实行有利于和谐社会的实现:有利于公民美德的重塑以及保障和促进公共政策的合法性.但是由于其制度化和程序化规范的缺失与不足;公共利益的难以确定性和公民参与能力的贫困等因素制约着协商民主的发展,我们必须加强作为民主政治发展的方向和前景的协商民主制度建设,提高公民参与的能力和素质.     

环境习惯法对少数民族地区环境法制建设的贡献——以青海果洛藏族自治州达日县和青海湟中县为例

将民族环境习惯法与国家法进行衔接和融合,既是少数民族地方环境法制建设的需要,也是民族环境习惯法现代化的合理进路。具体而言,三江源地区环境习惯法可以成为国家环境立法的来源,并有助于环境法律的实施,同时能够弥补环境立法的空缺。     

Budgeting for Accountability: A Comparative Study of Budget Reforms in the United States during the Progressive Era and in Contemporary China

Budgeting is an important mechanism for ensuring public accountability. How do budget reforms in the United States during the Progressive Era compare to those in contemporary China? Are administrative and legislative budget controls essential to an effective, efficient government? Though the two countries differ in many respects, significant parallels between their budget reforms are evident. In the United States, electoral accountability alone does not guarantee overall government accountability if proper budgetary institutions are absent. China's recent budget reform reveals that it is possible to develop accountability, absent open elections, but with limitations and constraints. Lessons on budgeting and accountability for other developing and transitional countries are drawn from this comparative study.
