Determination of age at the time of death based on the observation of cranial sutures has led to numerous studies with sometimes contradictory results. The initial hypothesis being that suture closure is part of an age-related physiological process, the conflicting results have been interpreted by various authors as secondary to the choice of sutures, under the co-existing influence of pathological factors or genetic factors, or even independent of age. Despite these differences, macroscopic methods remain much used in anthropology and in forensic medicine. In our work, we evaluated the value of the degree of closure of the frontosphenoidal suture in estimating age at death of mature subjects, with the secondary objective of establishing a linear regression which could be used in routine practice. The study concerned bone specimens from individuals whose age, sex and medical history were known. Macroscopic observation was carried out on the ectocranial and endocranial sides according to four stages of closure previously defined. 290 sutures were taken from a population of whom two-thirds were men. The method can be repeated and reproduced and the regression established shows the confidence range for average error to be +/-1.5 years. While this result is of interest in terms of precision in prediction for a group of people, the prediction range is too great (+/-23 years) to be applicable to a single individual as part of a forensic procedure. 相似文献

On a hot September night in 1984, I set foot in China for the very first time. After a long wait at Beijing International Airport, I decided, out of sheer despair, to hail a taxi, even though my Chinese was very limited. On the way to the (then) Beijing Institute of Foreign Languages, I started an alarmingly hesitant conversation, more body language than anything, with the driver. 相似文献

Although plant clinics are considered an important mechanism in the service delivery to farmers, not much is known about their functioning in the daily reality of plant doctors and farmer-clients. This article reports on an exploratory study describing the functioning of eight plant clinics in Rwanda. Personal and organisational commitment, publicity, and proactive communication with farmers and local leaders are key factors explaining higher attendance of some clinics. Farmer attendance is under-reported by 40–50%. Data management needs improvement to make clinic records reliable tools for decision-makers. This type of assessment can help improve operations and realise the plant clinics’ potential. 相似文献

目的通过实验研究用视频方法鉴定车速结果的准确性及其影响因素。方法在选定的实验场地上,让实验车辆以一定速度匀速通过一段距离,使用高空、垂直、斜角和车载四个位置的摄像机同时录制,将车速计算结果进行比较。结果理论和实验数据分析表明,误差的大小主要取决于:车速和帧速率,车体上参考点和路上参考点的对齐效果,还有行车距离的大小和播放器屏幕的大小等。结论用视频方法进行车速鉴定,相对于传统的用力学公式进行计算,其准确性和可信度较好;一般条件下,误差可在5%~10%之间估算;夜晚条件下,可在车灯的轮廓线上选择车体上参考点,炫目情况除外。 相似文献

This essay reacts to Philippe Van Parijs’s arguments in favor of English as the global lingua franca and in favor of the territorial protection of the languages of minority nations. I agree with both arguments. But I see the case for the lingua franca as a matter of convenience rather than justice. And I don’t link territorial protection to the emergence of English, but instead ground it as a fundamental right of national self-determination. 相似文献
