This paper speculates that due to antiquated criminal predator identification that the courts render less prison time to predators who continually commit abominable forms of crime than to first time violent offenders who were controversially convicted of the crime of murder. A sample of 89 respondents includes 61 males and 28 females incarcerated in high custody penitentiaries. The findings show that many predators are rarely charged and/or convicted of heinous predatory acts consequently their prison sentences averaged an eight year confinement as compared to nonpredators with an average of 25 years to life, often without parole. The hypothesis was supported and a criminal offender classification was created to explain various offender profiles. One implication of this finding is that methods of crime control including criminal profiles are inadequate to deal with one of America's worst problems—predatory attacks. An assumption that arises from this implication is that crime control is linked to popular myths produced by the media and therefore predators largely go unchecked. Further research should be concluded to determine efficient methods of intervention for various categories of predators. 相似文献

Modeling Bone Surface Morphology: A Fully Quantitative Method for Age‐at‐Death Estimation Using the Pubic Symphysis 下载免费PDF全文
Dennis E. Slice Ph.D. Bridget F. B. Algee‐Hewitt Ph.D. 《Journal of forensic sciences》2015,60(4):835-843
The pubic symphysis is widely used in age estimation for the adult skeleton. Standard practice requires the visual comparison of surface morphology against criteria representing predefined phases and the estimation of case‐specific age from an age range associated with the chosen phase. Known problems of method and observer error necessitate alternative tools to quantify age‐related change in pubic morphology. This paper presents an objective, fully quantitative method for estimating age‐at‐death from the skeleton, which exploits a variance‐based score of surface complexity computed from vertices obtained from a scanner sampling the pubic symphysis. For laser scans from 41 modern American male skeletons, this method produces results that are significantly associated with known age‐at‐death (RMSE = 17.15 years). Chronological age is predicted, therefore, equally well, if not, better, with this robust, objective, and fully quantitative method than with prevailing phase‐aging systems. This method contributes to forensic casework by responding to medico‐legal expectations for evidence standards. 相似文献

“Nervengas auf dem Meeresgrund” oder “Gefahr aus der Tiefe”. Solche und ?hnliche
Titel kennzeichnen Ver?ffentlichungen zum Thema Rüstungsaltlasten in Nord- und Ostsee. Dies ist
ein Zeichen der immer noch hohen Brisanz dieses Themas. In jüngster Vergangenheit sorgte die Verifikation
der Verklappung von ca. 90 t Tabun-Granaten südlich von Helgoland für Aufsehen. Fakt ist, dass
sich erhebliche Mengen Weltkriegsmunition in Nord- und Ostsee befinden. Leider mangelt es bisher nicht
nur an einer Aufkl?rung des von den Rüstungsaltlasten ausgehenden Risikos seitens der Naturwissenschaft,
sondern auch an einer rechtswissenschaftlichen Aufkl?rung eventuell bestehender Bergungs- und Sanierungspflichten.
Im folgenden Beitrag werden einige einschl?gige v?lkerrechtliche Vertr?ge mit Schwerpunktsetzung
im Seerecht auf das Vorliegen entsprechender Pflichten geprüft und gezeigt, dass Pflichten zur Bergung
der Altmunition bestehen. 相似文献

Das Thema Klimawandel und Naturschutz geh?rt derzeit zu den zentralen Gegenst?nden der politischen
und wissenschaftlichen Umweltdiskussion. Sowohl für Juristen als auch für Naturwissenschaftler
verschiedener Fachrichtungen stellt das Thema eine besondere Herausforderung dar. In den folgenden Er?rterungen
geht es vor allem um die Fragen, welches Instrumentarium das geltende europ?ische Recht zum Schutzgebietsnetz
Natura 2000 bereith?lt, um klimabedingten Arealverschiebungen von Tier- und Pflanzenarten Rechnung
tragen zu k?nnen, und wie dieses Instrumentarium de lege ferenda optimiert werden kann. Die Bearbeitung
der Fragen erfolgt auf der Grundlage rechts- und naturwissenschaftlicher Kooperation. 相似文献

Costly product liability lawsuits continue to plague the pharmaceutical industry, and insurance to cover these losses is severely inadequate. Furthermore, questionable regulation of drugs exists once a pharmaceutical has passed FDA approval. This article describes a plan that uses a capitalistic, rather than a governmental, approach to solve both the insurance and the quality control problems. Although the proposed plan has never been used to insure pharmaceutical companies, different permutations of it have been used to insure other litigation-prone industries. Success from the proposed insurance entity results from the combined knowledge of scientists and actuaries to provide both protection from product liability lawsuits for the pharmaceutical industry and enhanced post-market surveillance of pharmaceuticals. 相似文献

This study focused on a series of hypotheses regarding residents’ attitudes toward the police: (1) residents’ attitudes toward
the police are better represented by a two-dimensional model that differentiates global perceptions of the police from assessments
of the police in the respondents’ neighborhood; (2) the structure of residents’ attitudes toward the police is different for
Whites, African Americans, and Latinos; (3) direct experiences with the police in the respondents’ neighborhood will be more
strongly associated with the respondents’ assessment of police in their neighborhood than global perceptions of the police;
and (4) the influence of direct experiences with the police will be stronger for African Americans and Latinos than for Whites.
Results based on structural equation modeling offer strong support for the need to differentiate between global and neighborhood
perceptions of the police. The underlining measurement structure of attitudes toward the police was similar for Whites, African
Americans, and Latinos. However, the relationship between global and neighborhood attitudes was stronger for African Americans
and Latinos. Negative contact with the police was associated with both negative global and neighborhood assessments of the
police. Non-negative contact was associated with positive neighborhood perceptions of the police; however, only when it occurred
within the neighborhood. The influence of direct experiences with the police (both inside and outside the neighborhood) was
similar for Whites, African Americans, and Latinos. 相似文献

Decompositional odor analysis database 总被引:1,自引:0,他引:1

This study, conducted at the University of Tennessee's Anthropological Research Facility (ARF), describes the establishment of the Decompositional Odor Analysis (DOA) Database for the purpose of developing a man-portable, chemical sensor capable of detecting clandestine burial sites of human remains, thereby mimicking canine olfaction. This "living" database currently spans the first year and a half of burial, providing identification, chemical trends and semi-quantitation of chemicals liberated below, above and at the surface of graves 1.5 to 3.5 ft deep (0.45 to 1.0 m) for four individuals. Triple sorbent traps (TSTs) were used to collect air samples in the field and revealed eight major classes of chemicals containing 424 specific volatile compounds associated with burial decomposition. This research is the first step toward identification of an "odor signature" unique to human decomposition with projected ramifications on cadaver dog training procedures and in the development of field portable analytical instruments which can be used to locate human remains buried in shallow graves. 相似文献

Analysis of length polymorphism at short tandem repeat (STR) loci utilizing the polymerase chain reaction (PCR) process has proven to be an ideal assay for human identification purposes. The short length of STR loci coupled with the amplification of target sequence through PCR allows for a robust, sensitive, and specific assay for highly polymorphic markers. A multiplex containing fifteen STR loci plus the gender-determining locus Amelogenin was developed to provide a single amplification/detection of all CODIS (Combined DNA Index System) STR loci (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, TH01, TPOX, and vWA) as well as two internationally-accepted STRs (D2S1338 and D19S433). By incorporating five-dye fragment analysis technology and non-nucleotide linkers, previously optimized AmpFlSTR kit primer sequences have been maintained. This kit has been developed in accordance with the standards of the forensic community as defined by the DNA Advisory Board. Validation studies were performed to include developmental validation, and the results support the use of the AmpFlSTR Identifiler PCR Amplification Kit for human identity and parentage testing. 相似文献
