The objectives of our study were to investigate the dose–response relationship of the TASER X26 discharge duration in an anesthetized swine model. Fourteen swines were anesthetized and then exposed to TASER X26 discharge for 5 sec (n = 5) or for 10 sec (n = 6). The sham control group (n = 3) was anesthetized and studied using the same protocol except TASER X26 discharges during the experiments. Hemodynamic parameters were obtained. Blood pressure and total peripheral resistance decreased significantly after TASER discharge and returned to baseline value at 15 min after 5 sec of TASER discharge but did not return to baseline values during the 30‐min observation period after 10 sec of TASER discharge. Repetitive TASER X26 discharge resulted in adverse physiologic events with a dose–response relationship related to the duration of TASER X26 discharge in an anesthetized swine model. 相似文献

Abstract: Radiographs and computed tomography (CT) images have been increasingly applied and accepted in forensic sciences. Along with radiographs and CT images, the frontal sinus is often used for the individual identification because of its unique and unchangeable characteristics. The purpose of this study is to define the usefulness of three‐dimensional (3‐D) images of the frontal sinus for identification. CT images from 119 Korean cadavers were built up for 3‐D reconstruction and surveyed with 15 measurements. The total volume of the sinus, some nonmetric characteristics, and the bilateral asymmetry index in men differed significantly from those in women (p < 0.05). The digit codes, six sections and 10‐digit number, were almost able to accurately identify individuals (98%). This study showed a statistical difference between the sexes and classified the fused and prominent middle sinuses for the first time. This proposed method for identification is more accurate than those used in other studies. 相似文献

Although the international community has recently promoted legislation as an important reform strategy for ending female genital cutting (FGC), there exist divergent views on its potential effects. Supporters argue that legal prohibition of FGC has a general deterrent effect, while others argue legislation can be perceived as coercive, and derail local efforts to end the practice. This study examines the range of responses observed in rural Senegal, where a 1999 anti‐FGC law was imposed on communities in which the practice was being actively contested and targeted for elimination. Drawing on data from a mixed‐methods study, we analyze responses in relation to two leading theories on social regulation, the law and economics and law and society paradigms, which make divergent predictions on the interplay between social norms and legal norms. Among supporters of FGC, legal norms ran counter to social norms, and did little to deter the practice, and in some instances incited reactance or drove the practice underground. Conversely, where FGC was being contested, legislation served to strengthen the stance of those contemplating or favoring abandonment. We conclude that legislation can complement other reform strategies by creating an “enabling environment” that supports those who have or wish to abandon FGC. 相似文献

Abstract This paper considers pedagogical questions surrounding the teaching of law to non‐lawyers. It draws on research into the teaching, learning and assessment of law in social work education. The research comprised a systematic review of international literature, a practice survey, focus groups with students and practice teachers, and two stakeholder conferences. The evidence suggests that law teaching in social work education is of particular interest in highlighting key dimensions of education practice that affect students’ learning. The paper provides some signposts towards research‐informed organisation of teaching, learning and assessment, and highlights important areas for further study. 相似文献

Shoeprints left at the crime scene provide valuable information in criminal investigation due to the distinctive patterns in the sole. Those shoeprints are often incomplete and noisy. In this study, scale‐invariance feature transform is proposed and evaluated for recognition and retrieval of partial and noisy shoeprint images. The proposed method first constructs different scale spaces to detect local extrema in the underlying shoeprint images. Those local extrema are considered as useful key points in the image. Next, the features of those key points are extracted to represent their local patterns around key points. Then, the system computes the cross‐correlation between the query image and each shoeprint image in the database. Experimental results show that full‐size prints and prints from the toe area perform best among all shoeprints. Furthermore, this system also demonstrates its robustness against noise because there is a very slight difference in comparison between original shoeprints and noisy shoeprints. 相似文献

Variability in ridge density in a sub‐Saharan population sample was studied by counting ridges in three fingerprint areas (two distal regions, radial and ulnar, and one proximal region) on the epidermal surface of the distal phalanx. Study material was obtained from the fingerprint impressions of 100 male sub‐Saharan subjects aged between 18‐ and 48‐years old. The results were compared with those obtained from a Spanish population sample. Sub‐Saharan males presented lower ridge density than Spanish males in the distal regions (radial and ulnar) of all fingers, whereas differences in the proximal region were only observed on some fingers. Using the differences observed between these populations, the likelihood ratio for inferring membership of one of the populations from a fingerprint of unknown origin was calculated; therefore, a ridge density of 14 or less for both areas (ulnar and radial), support an origin sub‐Saharan versus Spanish population. 相似文献

This study highlights complexities associated with postsurgical trauma interpretation of a 76‐year‐old female patient from a psychiatric institution in Mexico. The skeletal analysis identified complications from an unsuccessful surgical operation for an intertrochanteric fracture of the femur. An improperly placed surgical plate resulted in nonunion due to limited contact between fracture margins. However, it is unclear whether this resulted from surgical complications, ineffective postoperative care, or from the decedent's limited ability to follow postoperative care instructions. Additionally, failure of the plate resulted in degenerative changes to the acetabulum. These complications, associated with degenerative changes to upper limb joints, suggest significant mobility issues. The pattern of antemortem trauma and contextual information support a conclusion of postoperative medical neglect, a documented problem in psychiatric institutions in Latin America. This study provides insight into the relevance of detailed trauma assessment of skeletal remains in cases where neglect and human rights violations are suspected. 相似文献

Rib fractures are considered highly suspicious for nonaccidental injury in the pediatric clinical literature; however, a rib fracture classification system has not been developed. As an aid and impetus for rib fracture research, we developed a concise schema for classifying rib fracture types and fracture location that is applicable to infants. The system defined four fracture types (sternal end, buckle, transverse, and oblique) and four regions of the rib (posterior, posterolateral, anterolateral, and anterior). It was applied to all rib fractures observed during 85 consecutive infant autopsies. Rib fractures were found in 24 (28%) of the cases. A total of 158 rib fractures were identified. The proposed schema was adequate to classify 153 (97%) of the observed fractures. The results indicate that the classification system is sufficiently robust to classify rib fractures typically observed in infants and should be used by researchers investigating infant rib fractures. 相似文献

The removal of judicial independence from the motherland for several Commonwealth countries was fraught with difficulties. The determination of where final national appeals would lie has had a most colourful history in the Commonwealth. An extension of judicial dependence may arguably be expressed in the manner in which a state address disputes of international law and its choice of the appropriate tribunal for redress. It is argued in this article that independence did not seem to indicate that some Member States were willing to relinquish their desire to move too far away from the family of the British Commonwealth. Consequently, in accepting the Option Clause of the International Court of Justice (ICJ), a number of Commonwealth Member States entered a reservation which, inter alia, excludes disputes with the government of any country that is a Member of the British Commonwealth. Although today only eight Commonwealth Member States (including Britain) maintain this exclusionary clause, to the extent that these eight may find themselves bound by this clause presents some difficulty when there are disputes among these Member States. The author highlights these difficulties by examining the case of Mauritius and the Chagos Archipelago. Ultimately, the present day Commonwealth seeks dispute settlement through peaceful means, with an absolute respect for the rule of international law governing relations within and among its Member States. 相似文献
