恶意失权规则的价值分析

物权的变动只有经过公示程式,才具有对社会的公信效力,交易安全方可得到确实保障。现行的善意保护规则虽然可以暂时性地弥补公信力的不足,但终究不是法治国家之恰当选择。当然,采纳能够有效保证物权变动公信力的物权行为无因性规则,并非没有限度。不过,缺憾的存在并不可怕,我们可以通过造就恶意失权制度,以矫正物权行为无因性规则的缺陷。     

Protecting digital identity in the cloud: Regulating cross border data disclosure

Widespread use of cloud computing and other off-shore hosting and processing arrangements make regulation of cross border data one of the most significant issues for regulators around the world. Cloud computing has made data storage and access cost effective but it has changed the nature of cross border data. Now data does not have to be stored or processed in another country or transferred across a national border in the traditional sense, to be what we consider to be cross border data. Nevertheless, the notion of physical borders and transfers still pervades thinking on this subject. The European Commission (“EC”) is proposing a new global standard for data transfer to ensure a level of protection for data transferred out of the EU similar to that within the EU. This paper examines the two major international schemes regulating cross-border data, the EU approach and the US approach, and the new EC and US proposals for a global standard. These approaches which are all based on data transfer are contrasted with the new Australian approach which regulates disclosure. The relative merits of the EU, US and Australian approaches are examined in the context of digital identity, rather than just data privacy which is the usual focus, because of the growing significance of digital identity, especially to an individual's ability to be recognized and to transact. The set of information required for transactions which invariably consists of full name, date of birth, gender and a piece of what is referred to as identifying information, has specific functions which transform it from mere information. As is explained in this article, as a set, it literally enables the system to transact. For this reason, it is the most important, and most vulnerable, part of digital identity. Yet while it is deserving of most protection, its significance has been largely under-appreciated. This article considers the issues posed by cross border data regulation in the context of cloud computing, with a focus on transaction identity and the other personal information which make up an individual's digital identity. The author argues that the growing commercial and legal importance of digital identity and its inherent vulnerabilities mandate the need for its more effective protection which is provided by regulation of disclosure, not just transfer.     

Effect of Substrate Interferences from High‐Density Polyethylene on Association of Simulated Ignitable Liquid Residues with the Corresponding Liquid

The effect of substrate interferences from high‐density polyethylene (HDPE) on the ability to associate an ignitable liquid residue with the corresponding liquid standard, using statistical procedures, is demonstrated. Gasoline, kerosene, and lighter fluid, at three different evaporation levels, were spiked onto HDPE and subsequently burned to generate simulated ignitable liquid residues (ILRs). Samples were extracted using a passive headspace procedure and analyzed by gas chromatography–mass spectrometry. The total ion chromatograms were subjected to data pretreatment procedures prior to principal components analysis and Pearson product moment correlation. Using the combination of these statistical procedures, simulated ILRs were successfully associated with the corresponding liquid type, despite the presence of compounds inherent to the HDPE substrate, as well as those resulting from pyrolysis of the substrate.     

Team Characteristics and Team Member Knowledge,Skills, and Ability Relationships to the Effectiveness of Cross‐Functional Teams in the Public Sector

Abstract

This study examines members of cross‐functional teams in the public sector for the necessary knowledge, skills, and ability (KSA) to be effective team members. It was determined that members of cross‐functional teams in the public sector possess the necessary KSA to perform effectively. The following characteristics are statistically significant factors: (1) years of professional work experience; (2) frequency of team participation; (3) the type of team training, i.e., collaboration and performance management; and (4) situational entry to team assignments (volunteered, assigned, requested), specifically volunteer and requested. The findings are significant in that managers within the government have some guidelines on team formation. They now know who should be team members, team members should be volunteers, and management should ensure that the team members have specific training in the areas of team collaboration and performance management. The findings are significant for employees as well. To acquire experience, employees should be interested in participating in a team environment (i.e., volunteering for the assignment). They should participate on numerous teams, so that they can become more effective as team members. Employees should acquire training in specific team skills (i.e., collaboration and performance management) to help them better understand how to work within the team and the team members and get results.     

Comparing Methods to Assess Intraobserver Measurement Error of 3D Craniofacial Landmarks Using Geometric Morphometrics Through a Digitizer Arm

Intraobserver error (INTRA‐OE) is the difference between repeated measurements of the same variable made by the same observer. The objective of this work was to evaluate INTRA‐OE from 3D landmarks registered with a Microscribe, in different datasets: (A) the 3D coordinates, (B) linear measurements calculated from A, and (C) the six‐first principal component axes. INTRA‐OE was analyzed by digitizing 42 landmarks from 23 skulls in three events two weeks apart from each other. Systematic error was tested through repeated measures ANOVA (ANOVA‐RM), while random error through intraclass correlation coefficient. Results showed that the largest differences between the three observations were found in the first dataset. Some anatomical points like nasion, ectoconchion, temporosphenoparietal, asterion, and temporomandibular presented the highest INTRA‐OE. In the second dataset, local distances had higher INTRA‐OE than global distances while the third dataset showed the lowest INTRA‐OE.     

家兔血液和尿液中氯胺酮浓度的相关性

目的研究家兔尿液中氯胺酮及代谢物去甲氯胺酮浓度与血药浓度的动态相关性。方法实验家兔分为氯胺酮灌胃组、静脉注射组和对照组,分别于染毒前和染毒后不同时间点收集尿液和血液。气相色谱/质谱联用(GC/MS)全扫描定性、气相色谱(GC)定量分析血液和尿液样品中氯胺酮及去甲氯胺酮的浓度。采用双变量Pearson相关分析研究尿液中药物浓度和血药浓度的相关性。结果氯胺酮灌胃组和静脉注射组给药后各时间点氯胺酮及去甲氯胺酮在尿液和血液中的浓度相关系数范围在0.11～0.69之间。结论氯胺酮及去甲氯胺酮在尿液和血液中的浓度相关性较差,尿液药物浓度并不能直接反映血药浓度,因此用尿液中氯胺酮浓度推断血药浓度时应慎重考虑。     

A Multimodal Fusion Approach for Bullet Identification Systems

In the field of forensic science, bullet identification is based on the fact that firing the cartridge from a barrel leaves exclusive microscopic striation on the fired bullets as the fingerprint of the firearm. The bullet identification methods are categorized in 2‐D and 3‐D based on their image acquisition techniques. In this study, we focus on 2‐D optical images using a multimodal technique and propose several distinct methods as its modalities. The proposed method uses a multimodal rule‐based linear weighted fusion approach which combines the semantic level decisions from different modalities with a linear technique that its optimized modalities weights have been identified by the genetic algorithm. The proposed approach was applied on a dataset, which includes 180 2‐D bullet images fired from 90 different AK‐47 barrels. The experimentations showed that our approach attained better results compared to common methods in the field of bullet identification.
