The Effect of Decomposition on the Efficacy of Biometrics for Positive Identification

Biometrics, unique measurable physiological and behavioral characteristics, are used to identify individuals in a variety of scenarios, including forensic investigations. However, data on the longevity of these indicators are incomplete. This study demonstrated that iris and fingerprint biometric data can be obtained up to four days postmortem in warmer seasons and 50 + days in the winter. It has been generally believed, but never studied, that iris recognition is only obtainable within the first 24 hours after death. However, this study showed that they remain viable for longer (2–34 days) depending upon the environmental conditions. Temperature, precipitation, insects, and scavenger activity were the primary factors affecting the retention of biometrics in decomposing human remains. While this study is an initial step in determining the utility of physiological biometrics across postmortem time, biometric research has the potential to make important contributions to human identification and the law enforcement, military, and medicolegal communities.     

Failure of anthropometry as a facial identification technique using high-quality photographs

Anthropometry can be used in certain circumstances to facilitate comparison of a photograph of a suspect with that of the potential offender from surveillance footage. Experimental research was conducted to determine whether anthropometry has a place in forensic practice in confirming the identity of a suspect from a surveillance video. We examined an existing database of photographic lineups, where one video image was compared against 10 photographs, which has previously been used in psychological research. Target (1) and test (10) photos were of high quality, although taken with a different camera. The anthropometric landmarks of right and left ectocanthions, nasion, and stomion were chosen, and proportions and angle values between these landmarks were measured to compare target with test photos. Results indicate that these measurements failed to accurately identify targets. There was also no indication that any of the landmarks made a better comparison than another. It was concluded that, for these landmarks, this method does not generate the consistent results necessary for use as evidence in a court of law.     

FUTURE CHILD'S RIGHTS IN NEW REPRODUCTIVE TECHNOLOGY:THINKING OUTSIDE THE TUBE AND MAINTAINING THE CONNECTIONS

This article considers whether children born through assisted human reproduction are entitled to information about their biological origins. It examines the issue both from a clinical perspective, citing social science research and the personal narratives of donor‐conceived children, and from a legal perspective, outlining the extent of a child's “right to know” in different jurisdictions. The article suggests that a uniform legal approach is needed that will recognize the right of all children to access details about their identity and conception, for the sake of their psychological well‐being. The article includes a fact scenario that considers the situation of a donor‐conceived child who has become the subject of a custody dispute, and who has not been told the circumstances of his conception.     

Reproductive Health: Morals,Margins and Rights

Reproductive interventions and technologies have the capacity to generate profound societal unease and to provoke hostile reactions underpinned by various moral concerns. This paper shows that this position currently goes relatively unchecked by the European Court of Human Rights, which allows the margin of appreciation and consensus doctrines significantly to limit the scope of reproductive rights under the right to respect for private and family life under Article 8. This occurs both in relation to the interest in avoiding reproduction at stake in abortion, and that in achieving it at stake in medically assisted reproduction. The paper demonstrates significant flaws in the Court's framing and deployment of these doctrines in its reproductive jurisprudence. It argues that, as regards existing and upcoming reproductive interventions and technologies, the Court should attend to the concept of reproductive health, long recognised in international conventions and policy materials.     

论人工生殖子女父母身份之认定

传统民法中父母子女关系的建立,血缘与怀胎是母亲同时具备的要素,法律上兼以二者作为认定母子关系的指标。随着医学科技的发达,人工生殖技术使得血缘与怀胎间的相连性不再理所当然,不孕夫妻可以借用他人的精卵通过体内或体外受精,使妻孕育分娩子女,甚至可以将不孕夫妻的受精卵植入他人的子宫怀胎分娩,使得人类的繁衍可以在血缘之外的母体进行。生殖科技对现行法律制度提出了诸多挑战,人工生殖子女之父母身份的认定问题尤为突出。为避免因采用特殊规则形成人工生殖子女为特殊子女的不当认识,立法上应力求采用与自然生殖同样的父母认定标准确定人工授精子女的亲子关系,即依据出生事实确定谁是母亲,根据婚生推定及否认制度确定谁是父亲,丈夫的术前同意限制其对子女的婚生否认权的行使;立足于有限性开放代理孕母的观点,确定代孕子女的父母身份时,法律应突破传统的分娩者为母亲的观念,通过特殊立法规定遗传父母为代孕子女之法律父母。     

双针挂针疗法结合温和灸治疗周围性面瘫急性期疗效观察

目的 观察双针挂针疗法结合温和灸悬灸翳风穴治疗周围性面瘫急性期的临床疗效。方法 将60例符合周围性面瘫急性期诊断标准的患者随机分为观察组与对照组,每组30例。在急性期单纯使用基础药物治疗的基础上,观察组采用双针挂针疗法,并辅以温和灸,对照组则不加用针刺治疗。两组各治疗7 d后,均改用常规针刺手法,以7 d为1个疗程,共治疗3个疗程。观察两组患者治疗前、治疗第7天及治疗第21天面神经功能评分及疗效。结果 观察组基于面神经功能评分的疗效优于对照组（P＜0.05）。两组患者治疗7 d、21 d后面神经功能评分均显著高于治疗前（P＜0.05）;治疗7、21 d后,观察组患者面神经功能评分均显著高于对照组（P＜0.05）。结论 在周围性面瘫急性期使用双针挂针疗法结合温和灸的治疗方案,可恢复患侧面神经功能,改善患者预后。

Beyond the sphere of the English facial approximation literature: ramifications of German papers on western method concepts

In the English literature, facial approximation methods have been commonly classified into three types: "Russian,"American," or "Combination." These categorizations are based on the protocols used, for example, whether methods use average soft-tissue depths (American methods) or require face muscle construction (Russian methods). However, literature searches outside the usual realm of English publications reveal key papers that demonstrate that the Russian category above has been founded on distorted views. In reality, Russian methods are based on limited face muscle construction, with heavy reliance on modified average soft-tissue depths. A closer inspection of the American method also reveals inconsistencies with the recognized classification scheme. This investigation thus demonstrates that all major methods of facial approximation depend on both face anatomy and average soft-tissue depths, rendering common method classification schemes redundant. The best way forward appears to be for practitioners to describe the methods they use (including the weight each one gives to average soft-tissue depths and deep face tissue construction) without placing them in any categorical classificatory group or giving them an ambiguous name. The state of this situation may need to be reviewed in the future in light of new research results and paradigms.     

魁奈的经济表与马克思的经济表

魁奈的经济表曾引起马克思的极大兴趣。马克思在深刻地解析了魁奈经济表的图式之后,着手创建社会资本再生产理论时,首先创绘出了自己的经济表。应该承认,马克思的经济表和魁奈的经济表之间确存有某些内在联系。魁奈的经济表给予马克思诸多启发,马克思的经济表使魁奈的天才尝试成为真正的科学。虽然马克思最终放弃了用经济表的形式表述自己的社会再生产模型,但经济表却搭建起了他的社会资本再生产理论框架,是马克思社会再生产理论的雏型。     

Farm transmission and the commercialization of agriculture in northern Maine in the second half of the 19th century

The transition to capitalism has been one of the most discussed issues in the historiography of the rural United States in the 18th and 19th centuries, but the typology, and the “market revolution” construed upon it, are problematic. The article explores some of these problems by examining the commercialization of eastern Canadian agriculture, which was a prolonged process starting in the beginning of the 19th century in the St. Lawrence–Great Lakes axis and ending during the 1960s in the outlying parts of Quebec, Ontario, and the Maritime Provinces. It is difficult to identify clear trends in the numbers yielded by evidence from this region for the time period in question. Highly commercial farms were more likely than the others to transfer all their property to their children. Deficit farmers were much more likely than the others to transfer all their property to outsiders. But the data do not support the view that farmers who were keen on turning their farms into moneymaking businesses adopted property transmission practices that were markedly different from the others. And before the 1830s, there was really no need to have strategies in place because land was plentiful.
