Determination of Trace Elemental Concentrations in Document Papers for Forensic Comparison Using Inductively Coupled Plasma–Mass Spectrometry

Abstract:  With improvements in manufacturing procedures, comparing physical characteristics of paper samples may not offer sufficient discrimination among different vendors. In this work, the potential to differentiate paper samples based on trace element concentrations was investigated. Paper samples from two different vendors were microwave-digested and trace element concentrations (Mg, Al, Mn, Fe, Sr, Y, Ba, Ce, and Nd) were determined using inductively coupled plasma–mass spectrometry. Differences in concentration were assessed statistically using two-way ANOVA and Tukey's honestly significant differences test. Elemental concentrations were shown to be consistent across a single sheet as well as within a single ream of paper for each vendor. Reams from vendor A were differentiated based on Al and Ba concentration while reams from vendor B were differentiated based on Mg, Mn, and Sr concentrations. Paper was differentiated according to vendor based on significant differences in Ba, Sr, Ce, and Nd concentrations.     

美国语境中的“法律人思维”

"像法律人一样思维"的论题不仅涉及到法律思维的种种基本问题,也与法律教育教学的内容和方法直接相关。但是,对它的理解却众说纷纭。法律人思维不是一种独立的思维类型,而是在特殊目的(权利与义务的确定)、制度化程序(程序规则)约束之下,于对抗性对话框架中(说服性对话)构建、分析、批判法律论证的思考活动。其基本特征是,针对一个法律主张,构建和表达合情理的论证,以获得一个合乎自己预期的法律裁决;它的核心是发现、分析和评价理由。     

Strategies for College Student Stalking Victims: Examining the Information and Recommendations Available

The college population is at a heightened risk for stalking victimization; yet it is suggested that college administrators have ignored stalking while focusing on other types of crimes, such as rape. Therefore, the present study seeks to examine the amount of attention universities are giving stalking as a crime that is a risk for their students. Additionally, this paper considers what types of information, recommendations, and strategies for effective responses to this type of victimization (if any) universities are providing to their students. In order examine university responses to stalking, a sample of Florida universities were observed by searching each university’s web page on the Internet. The data obtained from the university websites were analyzed through content analysis. Overall, it does in fact appear that Florida universities are addressing stalking in some manner, and the information they are providing to students is consistent with the current academic research.     

Nanotechnology,Nanomaterials, and the Potential for Regulatory Action by USEPA

The U.S. Environmental Protection Agency (USEPA) has recently taken steps toward directly regulating the potential environmental, health, and safety risks associated with the manufacture and use of nanomaterials, and indications are that it is considering additional regulatory action. More particularly, the agency appears ready to start relying more on the exercise of its existing statutory authorities—including the Toxic Substances Control Act and the Federal Insecticide, Fungicide and Rodenticide Act—than on voluntary industry efforts to address these potential risks. As a result, companies that work with nanomaterials should pay close attention to USEPA's activities in this arena.     

WHERE IS THE JUSTICE? PARENTAL EXPERIENCES OF THE CANADIAN JUSTICE SYSTEM IN CASES OF CHILD SEXUAL ABUSE*

Research concerning child victims of sexual abuse in the judicial system cites largely negative experiences and outcomes. However, few investigations focus on parental experiences of the justice system. Using a grounded theory method this Canadian study explored parental experiences of legal and judicial processes for child sexual abuse victims. Nineteen in‐depth interviews with parents encountering the justice system, as well as interviews with professionals working in those systems were analyzed. Results show a wide range of experiences, with parents reporting predominantly negative outcomes that potentially impede healing for children, indicating earlier judicial reforms have not been realized. Recommendations call for structural changes in the judicial system and more provision of parent‐focused supports.     

For the health of the economy and patent system: rationale and scope of patent attorney privilege

Legal context: There exists, in some countries, a patent attorney privilege.This privilege allows an actual or potential holder of patentrights to withhold from a court communications that it has hadwith its patent attorney. The privilege is not recognized inall jurisdictions and there is variation in the extent of theprivilege in those countries where it does exist. Key points: This article explores the rationale for the privilege in orderto see if there is a sound basis upon which to found it. Througha consideration of the justifications for other legal privileges,the article finds that patent attorney privilege is a justifiableprotection for communications between clients and their patentattorneys. If there was a possibility that the communicationswould have to be revealed in court, this may impact the fulland frank nature of the communications. Such communicationsassist patent attorneys, as professionals with expertise ina specialized field, to provide clients with appropriate andeffective advice. That advice goes directly to the maintenanceand benefit of the patent system and the overall economy. Practical significance: As a result of the variation in the extent of the privilegearound the world, there are moves afoot to reform its operation.This article reveals strong public policy reasons for the recognitionof a patent attorney privilege. These grounds also reinforcethe need to ensure that privilege is not unduly limited in itsoperation in any jurisdiction.     

Collaborative school planning and active schools: a case study of Lee County, Florida

To contribute to the understanding of the links between urban planning and school siting and, ultimately, the impact of both on physical activity, we conducted a case study of Lee County, Florida. Our study examined the extent of state-mandated collaboration between the Lee County School Board and Lee County government (e.g., the Lee County Department of Planning, the Office of Smart Growth, and the Department of Parks and Recreation). Specifically, we investigated planning processes under mandated coordination between the school board and the county and the impact of such coordination on the integration of land-use planning and school facility planning. By describing the process of mandated collaborative school planning in Florida, we illustrate the promise and pitfalls of such top-down legislation and offer insights to other state and local governments looking for ways to improve local planning and to increase physical activity among children.     

Pig-mentation: postmortem iris color change in the eyes of Sus scrofa

Experienced forensic pathologists and examiners may be familiar with the phenomenon of postmortem iris color change; however, only Knight, Simpson's forensic medicine, Arnold, London, 1997; Ref. 1 and Saukko and Knight, Knight's forensic pathology, 3rd ed., Arnold, London, 2004; Ref. 2 have referred to it in the literature, and to date, there have been no published scientific research studies on this taphonomic artifact. A controlled experiment was conducted of postmortem changes to isolated Sus scrofa eyes. The eyes (n = 137) were separated into three groups and each sample was observed for 3-day postmortem at a different temperature. In addition, a Sus scrofa head was obtained to observe postmortem changes of eyes in situ. All isolated blue eyes in the experiment, at room temperature and higher, changed to brown/black within 48 h. The in situ blue eye, at room temperature, turned brown/black within 72 h. If iris color consistently changes postmortem in humans, then this taphonomic artifact must be incorporated into victim identification protocol, including disaster victim identification software, and autopsy reports to prevent inaccurate victim identification and inappropriate exclusion from the identification process.
