The minimum postmortem interval can be estimated based on knowledge of the pattern of insect succession on a corpse. To use this approach requires that we take into account the rates of insect development associated with particular climatological conditions of the region. This study is the first to look at insect succession on decomposing carcasses in the high altitude plains (Paramo) in Colombia, at 3035 m above sea level. Five stages of decomposition were designated with indicator species identified for each stage: Callíphora nigribasis at the fresh stage; Compsomyiops verena at the bloated stage; Compsomyiops boliviana during active decay; Stearibia nigriceps and Hydrotaea sp. during advanced decay and Leptocera sp. for dry remains. A succession table is presented for carrion-associated species of the region, which can be used for estimating time since death in similar areas. Compsomyiops boliviana is reported for the first time in Colombia. 相似文献

This article examines the legacy of lynchings on contemporary whites' views of blacks as criminal threats. To this end, it draws on prior literature on racial animus to demonstrate the sustained influence of lynching on contemporary America. We hypothesize that one long‐standing legacy of lynchings is its influence in shaping views about blacks as criminals and, in particular, as a group that poses a criminal threat to whites. In addition, we hypothesize that this effect will be greater among whites who live in areas in America where socioeconomic disadvantage and political conservatism are greater. Results of multilevel analyses of lynching and survey data on whites' views toward blacks support the hypotheses. In turn, they underscore the salience of understanding historical forces, including the legacy of lynchings that influence contemporary views of blacks, criminals, and punishment policies. 相似文献

Advances in robotic handwriting technology create new challenges for forensic document examiners. In the past, devices such as the autopen were used to replicate signatures of government officials and corporate companies. In today's technology, companies such as Bond utilize robots to create written documents, which mimic natural patterns of handwriting. They generate customizable written samples by simulating pen movements and letter formations. Four forensic document examiners were given various reproduced questioned documents and utilized a modified ACE‐V (analysis, comparison, evaluation, verification) methodology to determine their genuineness. Examiners were able to make a distinction between the human writing samples and the skilled robotic equivalents. Several distinct features that are not seen in natural handwriting, such as even pen pressure and the superimposition of letterforms were observed in the robotic samples. Careful examination of identifying features of the Bond produced documents resulted in an opinion of nongenuineness. 相似文献

Developing and Testing a Soil Property Database for Forensic Applications in Southern California 下载免费PDF全文

The research sought to develop and test a forensic database of surface soil variability within previously mapped geologic and soil units in southern California. This type of database could be used to link suspects to crime scenes or determine source locations of soil sample evidence. Variability was evaluated using (i) color, (ii) magnetic susceptibility, and (iii) particle‐size distribution. Soil properties were analyzed for their ability to discriminate source areas using stepwise discriminant analysis. The percent correct predictions for geologic unit groups ranged from 30% to 100%. A blind study experiment matched four of the 18 samples to their unit of origin with the first choice by stepwise discriminant analysis, and eight were matched as second and third choices. The probability of selecting the appropriate unit of origin increased by 54% over random chance and eliminated as much as 99% of the field area as a potential search location. 相似文献

Citizens’ attitudes toward the death penalty have been effected by the availability of life without parole (LWOP). Our analysis focuses upon data from a representative sample of Kentuckians on death penalty attitudes. The factors influencing and related to death penalty support and compared to support for LWOP are considered along with a review of Kentucky survey findings from 1989–2016. The results reveal consistent support for LWOP over the death penalty. Male Kentucky residents with a college education were most likely to support life without parole over capital punishment while male conservatives did not. 相似文献

Over the past three decades, open licensing has evolved from hacker culture thought experiment to a transformative force in applied copyright across a range of industries. Yet very little empirical research exists to understand its disparate uses. This article examines social practices and attitudes about open licensing in order to examine the practical experience of creators and consumers who use this tool and in order to assess its value in moderating the negative consequences of extensive copyright. The discussion about the role of open licensing in creative industries and communities tends to be polarized into two vantage points. Either (1) it is a new, altruistic paradigm enabling creative communities to rework copyright to fit their vision for the cultural commons, or (2) it is a radical theft of creative labor, encouraged by Google and other digital industrial powerhouses, to cheat creators out of their share of profits. Both of these rhetorical vantage points presume a monolithic and largely either selfless or unaware base of creative laborers. We analyze data from a series of surveys across a range of creative fields and practices to show that creators employ open licensing for a variety of reasons, including instrumental purposes oriented toward skirting the many impediments created by institutions and law, rather than merely because they are unaware or selfless. 相似文献
