Effect of Different Attentional Conditions on ERP Detection of Visual AcuityCSCD

Objective: To study the effect of different attentional conditions on the event-related potential (ERP) components generated by the visual information stimuli related to visual acuity, and provide a theoretical reference for clinical forensic visual objective evaluation. Methods: With visual acuity optotypes as normal form of visual information stimuli, 15 volunteers as study subjects were supposed to account the visual acuity optotypes under the attentional condition of visual stimuli. Furthermore, the subjects were required to listen to the storytelling carefully under the non-attentional condition of visual stimuli, and after the examination, they needed to answer the story-related questions. All the EEG results of two different attentional conditions from the subjects were recorded by 32 channel ERP system. Results: Under two attentional conditions, P1 and P300 components were evoked by the visual acuity optotypes on supra-threshold and threshold visual acuity levels, while only P1 component were evoked by the visual acuity optotypes on sub-threshold levels. In the ERP waveforms evoked by the visual acuity optotypes on supra-threshold, P1 and P300 amplitudes under attentional condition were larger than that under non-attentional condition. Conclusion: Attentional conditions can influence the detection of visual acuity. P300 component can be used to distinguish the visual acuity levels with supra-threshold and subthreshold under non-attentional condition. © 2017 by the Editorial Department of Journal of Forensic Medicine.     

109例外伤性视损害的法医学分析

目的对外伤性视力损害的类型,机制及法医学鉴定进行分析。方法收集109例外伤性视损害案例,回顾性分析其两眼视差、屈光参差、受伤眼别、视力分布等项目。结果男女比例5.8:1,多见于30~59岁;单、双眼受伤的比例17.17:1,故意伤害案左、右眼受伤的比例1.39:1;受伤眼115目,83目达低视力或盲程度;两眼视力之差≥3行视标的95人(87.16%);屈光参差2.25D~6.00D的9人,6.00D的23人。结论两眼视差、屈光参差等问题在鉴定实践中并不少见,但我国鉴定标准尚未涉及,建议制定相关标准时关注双眼整体功能。     

占有脱离物与善意取得——兼论我国物权法的价值选择

在善意取得制度中,真正权利人的利益与善意受让人的利益相互冲突,传统民法理论向来将占有委托物与占有脱离物的区分作为一个重要的利益衡平工具.以民法权利外观信赖保护理论为基点,对区分肯定主义立法和区分否定主义立法进行评析,认为善意取得制度应扬弃占有脱离物与占有委托物的区分.在此基础上对我国物权法的价值选择进行评价,并对未来民法典中的善意取得制度提出了立法构想.     

当代视觉文化价值的多元化趋向

视觉文化价值观念的多元趋向,在世界范围内打破了单一的西方审美模式和观念。各种视觉文化均有自己独特的价值取向,它们在一定的时期和阶段是可以兼容的,也是能够独立生存的。

眼动心理学的理论、技术及应用研究

眼动即眼球的运动,它与注意及内部信息加工机制具有密切联系,存在着外源性的和内源性的两种控制,更多情况下受到任务或目的指引,因此眼动心理学研究已经成为当代心理学研究的一种有用范型.随着眼动仪向智能化、系列化、便携式方向的发展,其在心理学众多分支领域中的应用迅速扩展,同时基础性眼动研究及其理论建构也越来越受到重视.     

PRVEP P100潜伏时、空间频率阈值与视敏度关系法医学探讨

目的通过研究眼损伤后不同空间频率下阈刺激时图形翻转视觉诱发电位(PRVEP)相关指标与视敏度之间的关系,试图探讨运用视觉诱发电位推算视敏度的方法及价值。方法对四川大学华西医院眼科门诊钝性眼外伤病例81眼以及正常对照眼(199眼)进行图形翻转视觉诱发电位检查,采用不同空间频率的刺激产生视觉诱发电位波,记录各阈刺激时P100潜伏时与波幅。采用统计学方法描述检测结果,并进行线性相关与回归分析。结果阈刺激空间频率(X)与视敏度的对数值(Y)之间关系密切,可以通过建立两者之间的相应回归方程用以推算视敏度;各组阈刺激时PRVEP P100潜伏时(X)与视敏度(Y)的对数值存在较好相关性。结论建立相应的回归方程推算视敏度是一种较客观、准确的方法,在常规眼科检查的基础上,有利于客观、准确地评定视功能障碍。     

“The Symbol of Our Nation”: The Slouch Hat,the First World War,and Australian Identity

Australian scholars are now familiar with the tropes of the Anzac legend. This narrative describes the realisation of an Australian masculine identity, whose characteristics were forged on the Australian frontier and validated through the ordeal of battle. Though many writers contributed to this narrative, C.E.W. Bean, the official historian of the Australian Imperial Force during the First World War, is most closely associated with the popularisation of this myth, which fused frontier and martial masculinity into a national archetype.

This article will examine the role of the slouch hat as a material and visual device that helped communicate the Anzac legend. While most of the scholarship that examines the construction of this narrative focuses on its articulation in prose, this narrative was also popularised through other media. Artists drew symbols of the frontier into their paintings while museum directors arranged their artefacts to support this narrative. This article will argue that the slouch hat provided an essential visual device to connect the narratives of frontier and martial masculinity through the image of the Australian soldier.     

Comparison of Protocols for Measuring and Calculating Postmortem Submersion Intervals for Human Analogs in Fresh Water

Protocols for determining postmortem submersion interval (PMSI) have long been problematic for forensic investigators due to the wide variety of factors affecting the rate of decomposition of submerged carrion. Likewise, it has been equally problematic for researchers to develop standardized experimental protocols to monitor underwater decomposition without artificially affecting the decomposition rate. This study compares two experimental protocols: (i) underwater in situ evaluation with photographic documentation utilizing the Heaton et al. total aquatic decomposition (TAD) score and (ii) weighing the carrion before and after submersion. Complete forensic necropsies were performed as a control. Perinatal piglets were used as human analogs. The results of this study indicate that in order to objectively measure decomposition over time, the human analog should be examined at depth using the TAD scoring system rather than utilizing a carrion weight evaluation. The acquired TAD score can be used to calculate an approximate PMSI.
