Determination of average vehicle speed utilizing reverse projection

Reverse projection photogrammetry has long been used to estimate the height of an individual in forensic video examinations. A natural extrapolation would be to apply the same technique on a video to estimate the speed of an object by determining the distance traveled between two points over a set amount of time. To test this theory, five digital video recorders (DVRs) were connected to a single fixed camera to record a vehicle traveling down a track. The vehicle's speed was measured through Doppler radar by a trained operator and the speedometer of the vehicle was also recorded with a video camera. The recorded video was examined and the frames that best depict the beginning and end of the vehicles course were selected. Two reverse projection photogrammetric examinations were performed on the selected frames to establish the position of the vehicle. The distance between the two points was measured, and the time elapsed between the two points was examined. The outcome provided an accurate speed result with a standard degree of uncertainty. This study proves the feasibility of using video data and reverse projection photogrammetry to determine the speed of a vehicle with a limited set of variables. Further research is needed to determine how additional variables would impact the standard degree of uncertainty.     

The Accuracy and Repeatability of Reconstructing Single Bullet Impacts Using the 2D Ellipse Method

When a bullet punctures a surface, it leaves behind a bullet impact, which can be analyzed in order to determine the origin and trajectory path from which a bullet was discharged using many different scientific methods to reconstruct a shooting scene. The purpose of the research was to test the accuracy and repeatability of reconstructing the impact angle of single bullet impacts using the ellipse method. The research was conducted by firing various calibers of ammunition into drywall panels positioned at varying angles of incidence from 88° until ricochet occurred. This was done in order to determine which caliber type and angle of incidence are most accurate and precise for reconstructing a shooting scene. The study examined four caliber types fired into drywall panels, with 5 repeated shots for each of the 11 angles of incidence (n = 220). Furthermore, 31 participants partook in the study to estimate a bullet impact angle of incidence utilizing the ellipse method. The results show that the best performance (accuracy and repeatability) is seen with the measurements of the 0.45 caliber ammunition. When angle of incidences is low (<64°), the performance (accuracy and repeatability) was seen to be better in all caliber ammunitions. Overall, the data provided for single bullet impacts deposited in drywall show that the ellipse method is useful in providing measurements for most crime scene reconstruction purposes and has also demonstrated that results vary depending on the type of ammunition, firearm, and angle of incidence being examined.     

商标侵权惩罚性赔偿的制度构建

我国《商标法》2013年第三次修改时首次在知识产权领域引入惩罚性赔偿责任。实证分析表明,惩罚性赔偿在商标侵权诉讼中适用甚少且适用不规范的问题突出,未能充分发挥其遏制侵权行为的预期作用。究其原因,主要存在适用条件不明确、赔偿基数难确定、程序保障不充分等问题。为规范适用,充分发挥惩罚性赔偿的作用,需要从以下四个方面完善其制度构建:一是强化程序保障;二是明确适用条件;三是完善赔偿数额的计算;四是厘清惩罚性赔偿与法定赔偿的关系。     

Forensic Facial Reconstruction: A Systematic Review of Nasal Prediction Techniques

Prediction facial features from the skull are recurring theme on the forensic literature. The nose has been investigated since it has a significant role in facial recognition and the literature shows that there is not an universal method for nasal prediction. This study aimed to conduct a systematic review to analyze what are the most consistent techniques of nasal reconstruction. Primary studies describing or validating nasal reconstruction techniques in adults and published in journals of Forensic Sciences were included in this review. Tedeschi‐Oliveira's method positioned nasal tip with acceptable accuracy as Gerasimov's method. The Krogman's and Iscan's technique underestimated nasal projection in North Americans. The Prokopec's and Ubelaker's method obtained accuracy in Caucasoid. George's method presented results similar to reference standard in Caucasoid. In a supplementary way, studies are needed to accurately estimate the nasal width.     

网络信息安全犯罪的定量评价困境和突围路径——大数据背景下网络信息量化标准的反思和重构

刑法对网络安全的保护立场，正由网络运行安全转向网络信息安全。刑事立法更新不断增设网络信息安全专属罪名的同时，刑事司法的定量评价体系却未能一体构建，成为网络安全刑法保护的薄弱环节。当前网络信息安全犯罪的定量评价体系缺乏明确的逻辑主线，同时适用错位的“传统法益侵害程度”量化标准和模糊的“数据规模”新型量化标准，无法满足网络信息安全专属罪名司法适用的准确性和统一性需求，导致了司法适用的困境。消弭规范和技术之间的差异，以“信息规模”为定量评价核心的基础上，建构信息价值的分层评价模型，并将“组信息”作为基础的数据规模计量单位，是大数据时代背景下，突破网络信息安全犯罪司法定量评价困境的合理路径。     

Horses for courses: China's accommodative approach to food standard‐setting in response to the internationalization of regulation

This paper examines the evolution of China's food standard‐setting procedures from both domestic and international perspectives, particularly in the context of the internationalization of regulation. After the reform and opening‐up in 1978, state actors and leading enterprises monopolized the process of national food standard setting. With further participation in the global economy in the 21st century, China has become familiar with the international standard‐setting procedures and has modeled its domestic policymaking on these practices. This has resulted in a more transparent, inclusive, scientific, pluralized, and consensus‐based form of decisionmaking. By contrast, the standards of the strategic industries have been harmonized to the standards of international counterparts through a top‐down and authoritarian approach. This paper argues that China uses an accommodative approach, trichotomizing suitable standards and decisionmaking procedures in terms of inclusiveness and transparency, which suits the developmental needs of the domestic market, food export markets, and strategic industries.     

Confidence in an election authority and satisfaction with democracy: Evidence from a quasi-natural experiment of a failed election in Sweden

Contemporary research on electoral integrity has focused on the functioning, evaluation, and legitimacy of electoral processes in emerging democracies. By contrast, this study investigates whether a failed election in a well-established democracy can affect individuals' evaluations of the electoral management body, the Election Authority, and whether those evaluations affect satisfaction with democracy. Using the case of a Swedish regional election in 2010 that had to be rerun due to procedural mistakes in the vote handling, we found that, in the short term, individuals’ confidence in the Election Authority was reduced after it was announced that the election had to be rerun because of the mistakes. Subsequently, this decreased confidence was strongly associated with less satisfaction with democracy at the regional and national level. As good news for the authority, after a successful rerun election, confidence rebounded to the levels prior to the failed election.     

Uncovering land tenure insecurities: tips for tenure responsive land-use planning in Ethiopia

Land-use planning, although a mechanism for development, can also generate insecurity during its implementation. This article argues that tenure security and land-use planning should not be implemented in isolation from each other. It posits that land-use planning – rather than restricting the security of people's tenure – has the potential to serve as a means of securing tenure. The article explores tenure (in)security elements in land-use planning as a crucial challenge in the urban town of Gelan Sidama Awash, Ethiopia. Using data collected through stakeholders’ interviews, it uncovers their tenure security challenges, and outlines a set of measures for enhancing tenure security through land-use planning.     

‘Flat and fabulous’: women’s breast reconstruction refusals post-mastectomy and the negotiation of normative femininity

The ‘pinkification’ of breast cancer culture in recent years conflates women’s empowerment with the celebration of hyperfemininity. Consistent with this trend, reconstructive surgery post-mastectomy is increasingly normalised: restoring the breasts is to restore ‘lost’ femininity. Contextualised within the pressures of this normalisation, our article explores how women who decide against breast reconstruction negotiate their non-normative ‘flat’ bodies. We examine women’s posts in a breast cancer forum about their refusals of breast reconstruction. Using thematic and feminist post-structuralist analyses, we suggest that although health and body acceptance discourses enable resistance to embodied femininity norms, pressures to conform permeate practices related to appearance. Clothes and prosthetic breasts enabled forum participants to pass as ‘healthy’, ‘whole’, and ‘recovered’. The study’s findings emphasise the limitations to agency and resistance that emanate from the ways constraining gender discourses infiltrate every aspect of a woman’s life. In line with a critical awareness approach to breast cancer education, we discuss the possibilities of resistance afforded by the safe spaces of online communities.     

Investing in multi-stakeholder dialogue to address natural resource competition and conflict

How can multi-stakeholder dialogue help assess and address the roots of environmental resource competition and conflict? This article summarises the outcomes and lessons from action research in large lake systems in Uganda, Zambia, and Cambodia. Dialogues linking community groups, NGOs and government agencies have reduced local conflict, produced agreements with private investors, and influenced government priorities in ways that respond to the needs of marginalised fishing communities. The article details policy guidance in four areas: building stakeholder commitment, understanding the institutional and governance context, involving local groups in the policy reform process, and embracing adaptability in programme implementation.
