美国自然文化遗产管理经验及对中国有关改革的启示

美国是自然文化遗产资源丰富且管理较为成功的国家,其基本管理理念是根据遗产资源的公益性确定遗产资源的使命,然后建立与使命相应的资金机制、管理机制、经营机制、监督机制等,以确保管理能力、管理手段与管理目标相适应。本文以美国国家公园体系为例介绍了这种理念的形成过程和具体体现方式,总结了中国自然文化遗产管理制度与美国的差别,并在剖析中国有关改革的基础上提出了中国遗产管理应该借鉴美国的基本管理理念。     

Discovery and identification of new D13S317 primer binding site mutations

During the course of conventional testing of CODIS standards at the Alabama Department of Forensic Sciences, a sample with a heterozygous null genotype at D13S317 was discovered using the PowerPlex 1.1 kit (Promega, Madison, WI). The loss of both alleles was confirmed when the sample was amplified using PowerPlex 1.2 primers and resulted in a 9, 10 genotype at this locus. To determine the cause of the silent alleles, the ADFS designed D13S317 primers which encompassed the PowerPlex 1.1 D13S317 primer binding sites and sequenced the region. Both alleles showed the presence of two substitutions (T-->A and G-->T) at positions 1 and 5 (5'-->3') of the reverse primer (positions 196 and 200 of the sequence in GenBank accession number ). Since the mutations were identical on both alleles, they may be assumed to be of ancestral origin.     

Group therapy for women sexually abused as children: mental health before and after group therapy

Forty-five female outpatients sexually abused in childhood were offered a 2-year phase-divided group therapy. Before and after treatment and at 12 months follow-up, they answered questionnaires designed to elicit responses concerning psychological symptoms (Symptom Checklist; SCL-90) and sense of coherence (SOC). Symptoms for posttraumatic stress disorder (PTSD) were assessed before and after treatment. Inpatient days and sick listing days were assessed during 2 years before and 2 years after treatment. The psychological and PTSD symptoms were significantly reduced after treatment, and the SOC was increased as well. Inpatient days were decreased, and sick listing days increased but not significantly. Compared to a similar short-term focused therapy group and a waiting-list group there were no significant differences between the groups. Trauma-focused group therapy for women who were sexually abused in childhood seems to have promising effects on mental health, both concerning long-term and short-term approaches.     

Alcohol and drug use among rural and urban incarcerated substance abusers

A number of prisoners use drugs. Limited information is available about the extent to which urban and urban substance abusers differ in their drug use in criminal justice settings. In addition, many believe that rural areas are protected from drug use. However, findings from this study show only marginally statistical significant differences in drug use between incarcerated rural and urban drug users. It was expected that urban drug users would be more drug career involved with consistently higher levels of drug use and associated problems. Specifically, rural drug users in this study were older at age of first use of marijuana and cocaine; report fewer years of cocaine, hallucinogen, and heroin use; and report more alcohol and sedative use. Findings from this study suggest that rural and urban drug users are similar and that rural areas may be protective from some drug use but risky for other drug use.     

Crime scene investigations using portable,non-destructive space exploration technology

The National Institute of Justice (NIJ) and the National Aeronautics and Space Administration's (NASAs) Goddard Space Flight Center (GSFC) have teamed up to explore the use of NASA developed technologies to help criminal justice agencies and professionals solve crimes. The objective of the program is to produce instruments and communication networks that have application within both NASA's space program and NIJ programs with state and local forensic laboratories. A working group of NASA scientists and law enforcement professionals has been established to develop and implement a feasibility demonstration program. Specifically, the group has focused its efforts on identifying gunpowder and primer residue, blood, and semen at crime scenes. Non-destructive elemental composition identification methods are carried out using portable X-ray fluorescence (XRF) systems. These systems are similar to those being developed for planetary exploration programs. A breadboard model of a portable XRF system has been constructed for these tests using room temperature silicon and cadmium-zinc telluride (CZT) detectors. Preliminary tests have been completed with gunshot residue (GSR), blood-spatter and semen samples. Many of the element composition lines have been identified. Studies to determine the minimum detectable limits needed for the analyses of GSR, blood and semen in the crime scene environment have been initiated and preliminary results obtained. Furthermore, a database made up of the inorganic composition of GSR is being developed. Using data obtained from the open literature of the elemental composition of barium (Ba) and antimony (Sb) in handswipes of GSR, we believe that there may be a unique GSR signature based on the Sb to Ba ratio.
