优质旅游有效供给因素对我国旅游产业效率的影响及区域差异

优质旅游是新时代我国旅游产业发展的必然选择。通过采用三阶段DEA模型等方法,从支撑因素、产业发展及消费需求三个维度构建优质旅游有效供给的环境变量,并采用面板数据实证分析了优质旅游有效供给因素对我国旅游产业效率的影响与区域发展差异。研究结果表明,优质旅游有效供给环境变量对我国旅游产业效率影响显著,其中支撑因素水平和旅游消费水平促进效率提升,产业发展在一定程度上抑制效率增长;目前我国优质旅游有效供给总体水平不高,且不同区域及省份之间表现出一定差异。因此,应通过进一步优化支撑要素水平、建立旅游投资总量调控及质量监督机制、制定积极的消费引导政策、缩小区域差距等,促进产业效率改进,提高优质旅游有效供给总体水平。     

An Anthropological Examination of the Types of Skeletal Fractures Resulting from Fatal High (˃3 m) Free Falls,

Fatal falls from heights (?3 m) often result in blunt force trauma (BFT) to the skeleton. The fracture patterns that result from this BFT mechanism are well understood in forensic anthropology and forensic pathology; however, details of the specific types of fractures that result remain poorly documented. The aim of this study was to provide a detailed examination of the types of fractures that may result from fatal high falls. Fractures were recorded from 95 full‐body postmortem computed tomography scans of individuals known to have died from a high fall. Trauma was then analyzed taking into account the extrinsic and intrinsic variables known to influence a fall using multiple logistic regression. A total of 339 types of fractures were classified, of which 16 were significantly associated with this BFT mechanism. Classified fracture types will augment anthropological interpretations of the circumstances of death from BFT in cases of suspected high falls.     

A Fatal Case of Poisoning with Fentanyl Transdermal Patches in Japan

Fentanyl transdermal patches have been used to treat cancer‐ and noncancer‐related chronic pain. However, its inappropriate or illegal application may cause fatal poisoning. We herein present the case of a Japanese woman in her 40s who was found dead with seven 25‐μg/h fentanyl transdermal patches on her body. We established a detailed toxicological analysis procedure to quantify fentanyl, and its metabolite norfentanyl, and other drugs (acetaminophen, allylisopropylacetylurea, celecoxib, estazolam, promethazine, and sertraline) in human whole blood by ultra‐high‐performance liquid chromatography–tandem mass spectrometry. The measured fentanyl and norfentanyl concentrations in the femoral and cardiac blood were 0.051 and 0.072 μg/mL and 0.033 and 0.076 μg/mL, respectively. The decedent's fentanyl concentrations were consistent with previously reported postmortem blood levels for fatal cases of poisoning by fentanyl transdermal patches. Based on the decedent's case history, autopsy findings, and toxicological analyses, the cause of death was identified as intoxication with transdermal fentanyl.     

事件相关电位客观评估视敏度的法医学应用

目的研究不同视敏度水平的事件相关电位(event-related potential,ERP)成分特征,以期为视敏度的客观评定提供理论依据。方法选取16名被试进行单眼刺激。要求被试眼平视前方屏幕,注意屏幕中央的视觉刺激并对朝向不同的刺激进行计数。屏幕的中央会显示3种不同视敏度水平所对应的视标刺激图片,分别记录其ERP结果。结果 (1)阈上视敏度水平一致刺激的P_1振幅高于阈值、阈下视敏度水平一致刺激的P_1振幅,阈值和阈下视敏度水平一致刺激的P_1振幅差异无统计学意义,冲突刺激与一致刺激在3种视敏度水平的趋势类似。(2)阈上和阈值视敏度水平都出现了潜伏期在340~500 ms内的P300成分;阈下视敏度水平在相应的时间窗内无P300成分。3种视敏度水平的P_(300)振幅差异有统计学意义,振幅由大到小分别为阈上、阈值、阈下视敏度水平。结论 ERP技术可以成为法医学客观评定视敏度的新手段。

口蹄疫病毒A/WH/09株结构蛋白P1基因的克隆及其B细胞抗原表位的预测

对口蹄疫病毒(FMDV)A/WH/09株P1结构蛋白基因进行了扩增、克隆及序列测定。结果显示,FMDV A/WH/09株P1基因长2 208bp,包含完整的开放阅读框,编码736个氨基酸,其中VP1长636bp,编码212个氨基酸;VP2长654bp,编码218个氨基酸;VP3长663bp,编码221个氨基酸;VP4长255bp,编码85个氨基酸。采用DNAStar Protean软件对P1蛋白的二级结构、可塑性、亲水性、表面可及性及抗原指数等参数进行了综合分析,并预测其B细胞的抗原表位分布。结果表明,VP1、VP2和VP3上均有多个区域为B细胞抗原优势表位,VP4上也有少量潜在的B细胞抗原表位。与已鉴定的B细胞抗原表位相比,本试验所用方法预测的结果有较高的准确度,是一种较为先进的表位研究方法。     

Webcasters’ protection under copyright – A comparative study

This paper studies the fourth generation ‘peer-2-peer’ (P2P) file sharing technology which is also known as streaming technology from the technology point of view. It critically analyses the nature of streaming technology and assesses similarities to broadcasting for the purpose of copyright protection in the name of webcasting. In addition, it considers the possibility of protecting webcasting within the framework of broadcasting under copyright and the extent of broadcasters’ rights applicable to webcasters. Based on the conclusions derived from the discussion of UK, New Zealand, Italian and US law on streaming, WIPO Standing Committee on Copyright and Related Rights (SCCR) draft documents will be critically analyzed. The Last part of this work will offer suggestions as to how to protect webcasting (streaming technology) under the umbrella of copyright.
