Photogrammetric Documentation of Regions of Interest at Autopsy—A Pilot Study

In this pilot study, the authors tested whether photogrammetry can replace or supplement physical measurements made during autopsies and, based on such measurements, whether virtual computer models may be applicable in forensic reconstructions. Photogrammetric and physical measurements of markers denoting wounds on five volunteers were compared. Virtual models of the volunteers were made, and the precision of the markers' locations on the models was tested. Twelve of 13 mean differences between photogrammetric and physical measurements were below 1 cm, which indicates that the photogrammetric method has a high accuracy. The precision of the markers' location on the models was somewhat less, although the method is still promising and potentially superior to the current procedures used for reconstructions. The possibility to measure any distance on a body, even after the autopsy is concluded and the corpse is no longer available, is one of the biggest benefits of photogrammetry.

Inter-/Intra-observer Reliability of Hand Assessment Using Skin Detail: A Count-based Method

Skin detail of the hand is used in photographic comparisons, yet its reliability has not been evaluated. This study examines a count-based method for documenting skin features. In Part I, 14 individuals counted skin features on 40 color images of the hand, three of which were repeated. An average correlation value of 0.557 was obtained for interobserver assessment; values ranged from 0.545 to 0.832 for intra-observer assessment. The variation in correlation values for hands suggests that there are certain distinguishing characteristics that increase reliability. In Part II, 17 examiners assessed 20 nonrepeated grayscale images of hands by circling skin features. An average correlation value of 0.674 was obtained, but visual assessment of examiner markings suggested some examiners grouped features whereas others viewed them individually. The results suggest further research is warranted, some hands may be more suitable for comparisons, and a standardized method for examining skin features is needed.     

论建立公文质量管理体系

公文的本质特性决定了建立公文质量管理体系的必要性,建立公文质量管理体系也符合公文处理科学化和全面提高公文质量的要求。建立公文质量管理体系主要从公文运动过程和公文质量要素方面着手,需要领导重视,提高文秘人员素质,健全制度,改善处理手段。     

Form follows function: Applying photographic content analysis to forensic firearm identification

Drawing forensic conclusions from an image or a video is known as “photographic content analysis.” It involves the analysis of an image, as well as objects, actions, and events depicted in images or video. In recent years, photographic depictions of objects suspected as illegal firearms have substantially increased, appearing on CCTV surveillance footage, captured by mobile phones and shared on social media. However, the law in Israel states that a person can be charged with illegally possessing a firearm only if it can be proven that the object is capable of shooting with lethal bullet energy. This becomes more challenging in cases where the firearm was not physically seized, and the evidence exclusively consists of images and video. In this study, photographic content analysis was applied to images and video where objects suspected as commercial or improvised firearms had been depicted. An image and event sequence reconstruction video databases of both firearms and replicas were created in order to better define firearm-specific functional morphological features. We demonstrate that it is possible to classify an object as a firearm by analyzing the functional, and not only the esthetic, morphology in images and video. It is also shown that event sequence reconstruction in video may be used to infer that an object suspected as a firearm has the capacity to shoot by confirming the occurrence of a shooting act or shooting process. Thus, photographic content analysis may be used to forensically establish that an object depicted in an image or a video is a firearm by ruling out other known scenarios, and without physically seizing it.

Pyrographies: Photography and the good death

This essay theorizes the ethical potential of photography or what I call “pyrography” by enacting a version of care for death in attending closely to a sort of rehearsal for the deathbed in French photographer and writer Hervé Guibert's photo-novel Suzanne and Louise first published by Gallimard in 1980, the same year as Roland Barthes's famous essay on photography, Camera Lucida. The essay develops the transformative ethical possibilities of and queer political potentialities of pyrography by reading Guibert's project with his two elderly aunts in relation to the work of two of Guibert's intimates: Michel Foucault's “The Social Triumph of the Sexual Will” and Roland Barthes's Camera Lucida and Mourning Diary. In Mourning Diary, Barthes describes the plan for Camera Lucida as an ephemeral monument to his dead mother whose loss he calls, following the last work of psychoanalyst Donald Winnicott: “the catastrophe that has already occurred.” Through its own writing with fire of the death we fear that has already occurred and that we cannot access directly, photography may enable the kind of “as if” work or projective imaginative enactment for which Winnicott calls. This essay put this concept of the photographic pyre or pyrographies to work to characterize a kind of photographic act. Pyrography is a facture of and with the flammable, not of and about the past, but for the present and future. It is a practice of making volatile structures for feeling with the taboo scenes of the conjunction of old age, desire, and death that create spaces not just for mourning the losses that have actually happened. Pyrographies shape spaces in which one might begin to imagine and transact with care the losses and the letting go yet to come. Pyrographies, I am suggesting, trade in the illusions of presence. They give us the catastrophe that has already occurred in palpable form, enabling us to negotiate shame and fear but also desire toward the seemingly impossible: the good death.     

论摄影作品的独创性

摄影作品的独创性表现为摄影器材的选取、摄影参数的调整、摄影时机的选择和摄影者个性化的安排。制式的证件照片不构成摄影作品;体现拍摄时机的抓拍照片可以构成摄影作品;机器自动拍摄的照片一般不构成摄影作品,但体现了人工干预、人工选择的照片可以构成摄影作品。     

法律文书中的模糊词语初探

法律文书在大量使用确切性词语的同时,还必须适当选用模糊词语,选用模糊词语的目的其实也是为了更确切的表意。法律文书在表述难以具体确定的时间空间、无法或不必确定的程度范围、难于或无需准确描述的频率数量、带有预测推断性质的内容情节、不便或不宜直言的情景事实等状况时宜用模糊词语。运用模糊词语可以使法律文书的语义更确切、表述更严谨、文风更庄重、章法更协调。法律文书在使用模糊词语时一定要注意不能超越一定的“模糊度”,不能偏离具体的题旨语境,不能忽略其与确切性词语的对立统一。
