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.     

论纳税人诚实推定权的入法途径

诚实推定权由纳税人财产权与人格尊严权衍生而来,在立法中加以确认有助于落实税收法定、践行量能课税和提高纳税人遵从度。诚实推定权借鉴了刑法上的无罪推定和民法上的善意推定,其基本内涵是税务机关认为纳税人有少缴税款嫌疑时,应由该机关承担举证责任,证明强度应达到优势证据标准。我国应在修改《税收征收管理法》时,明确表达纳税人享有诚实推定权,同时准确界分纳税人的协力义务和税务机关的举证责任,强调逃税行为必须具备主观故意的要件,合理限定税收检查权。诚实推定权入法将对税收征纳实践产生影响,提高现有“计税依据明显偏低”的认定标准,使纳税人的正当理由诉求更有可能被认可,对逃税行为的界定也将更为精确。     

法医牙科学研究进展CSCD

法医牙科学是法医学与口腔医学的交叉学科,通过科学地收集、检测、评价牙科证据而为司法实践提供有法律效力的证明资料。本文从年龄推断,性别推断,种族、职业及生活习惯推断,个体识别,家庭暴力或虐待行为判定等方面对法医牙科学的应用现状进行综述,并对其未来应用进行展望,希望对法医牙科学体系进行不断的补充和完善,使其在法医学甚至司法实践中更好地发挥作用。     

国外药品不良反应损害救济制度述评及其对我们的启示

药品在发挥诊断、治疗、预防疾病功能的同时必然会伴随不良反应的发生。对于不良反应的后果是否应当救济 ,或在多大范围内救济 ?就这一问题 ,考察了德国、日本、美国以及我国台湾地区相关的判例和立法例 ,尽管上述各国和地区在救济方式或立法模式上有所差异 ,但对于药品常见且可预期之外的不良反应以及疫苗中毒所致人身损害应当救济则是一致的 ,这也是我国在完善或制定相关法律时值得借鉴的。     

关于破坏监管秩序罪的认定

破坏监管秩序,是罪犯在监狱及其他监管场所服刑期间时有发生的行为,破坏监管秩序,情节严重则构成犯罪。我国《刑法》第315条规定了破坏监管秩序罪的构成及其刑事责任。破坏监管秩序罪,是指被依法关押在监管场所服刑的罪犯,殴打监管人员,组织其他被监管人破坏监管秩序,聚众闹事,扰乱正常的监管秩序,殴打、体罚或指使其他人殴打、体罚其他被监管人,情节严重的行为。破坏监管秩序罪,处3年以下有期徒刑。     

"被害人自愿"与诈骗罪认定

行为人通过实施欺诈手段取得财产的行为不一定构成诈骗犯罪。诈骗犯罪中的欺诈手段和其他侵犯财产罪中实施的欺诈手段的根本区别是 :诈骗犯罪中的欺诈手段使被害人产生错误认识 ,其基于意志自由“自愿交付”财产。区分诈骗罪与盗窃、抢夺、抢劫、敲诈勒索等其他以实施欺诈手段侵犯财产的犯罪 ,必须从被害人在受到欺诈时的认识因素和意志因素两个方面来进行。     

Coming to Terms with Separatist Insurgencies

Although insurgencies may begin their rebellions with expressed desires for outcomes unacceptable to opposing governments, the desired insurgent outcomes sometimes undergo modification, creating conditions that can make governments more amenable to external mediation. In certain separatist conflicts, the likelihood of external mediation increases when the political redefinition of the state insisted upon by the insurgents undergoes a revision, from secession to self‐determination, understood as a variant of autonomy. In the same vein, although it may not happen concurrently, insurgent movements become more amenable to external mediation if and when opposing governments revise the preferred conflict outcome from a military defeat of the insurgents to a containment of the movement. These two developments can serve as objective referents helping external parties to identify a ripe moment in the conflict and initiate mediation. But the implementation of an agreement ending separatist conflict may not occur if the government fails to submit the proposed territorial bounds of autonomy to prior review by constituents. Potential spoilers among government constituents should be identified and recruited to participate in the negotiations so that the likelihood of agreement rejection is reduced. In some states, however, the legal mechanisms and political opportunities for constituents to act as spoilers do not exist.     

Implementation and Optimization of the Sodium‐Rhodizonate Method for Chemographic Shooting Distance Estimation

In shooting incident investigations where it is important to estimate the shooting distance, the sodium‐rhodizonate coloring method has been used for the visualization of GSR patterns extensively. This publication describes the optimization of this method by the use of a heated press for the transfer of GSR traces on garments, as well as variation of a number of other important process parameters. Our final aim for this project was to prepare a formal validation of the coloring method as prerequisite for its inclusion into the scope of ISO17025‐certified methods in the GSR Laboratory. A number of important factors and process parameters were identified, such as buffer composition and pH, type of textile used as a substrate and resolution of the documentation of the results. Results were tested using a synthetic proficiency test. Our optimized method has been found to be a very effective technique for visualization of macroscopic GSR traces.     

The anatomical diaspora: evidence of early American anatomical traditions in North Dakota

The current focus in forensic anthropology on increasing scientific certainty in ancestry determination reinforces the need to examine the ancestry of skeletal remains used for osteology instruction. Human skeletal remains were discovered on the University of North Dakota campus in 2007. After recovery, the osteological examination resulted in a profile for a 33- to 46-year-old woman of African descent with stature ranging from 56.3 to 61.0 in. The pattern of postmortem damage indicated that the remains had been prepared for use as an anatomical teaching specimen. Review of the American history of anatomical teaching revealed a preference for Black subjects, which apparently extended to states like North Dakota despite extremely low resident populations of people of African descent. This study emphasizes the need to examine the ancestry of older teaching specimens that lack provenience, rather than assuming they are derived from typical (i.e., Indian) sources of anatomical material.     

Human dental age estimation by calculation of pulp-tooth volume ratios yielded on clinically acquired cone beam computed tomography images of monoradicular teeth

Abstract: Secondary dentine is responsible for a decrease in the volume of the dental pulp cavity with aging. The aim of this study is to evaluate a human dental age estimation method based on the ratio between the volume of the pulp and the volume of its corresponding tooth, calculated on clinically taken cone beam computed tomography (CBCT) images from monoradicular teeth. On the 3D images of 111 clinically obtained CBCT images (Scanora^®3D dental cone beam unit) of 57 female and 54 male patients ranging in age between 10 and 65 years, the pulp–tooth volume ratio of 64 incisors, 32 canines, and 15 premolars was calculated with Simplant^® Pro software. A linear regression model was fit with age as dependent variable and ratio as predictor, allowing for interactions of specific gender or tooth type. The obtained pulp–tooth volume ratios were the strongest related to age on incisors.
