Intraobserver Error in Macromorphoscopic Trait Data, ,

As part of a much larger investigation into the use of macromorphoscopic trait data by forensic anthropologists to estimate ancestry from unidentified skeletal remains, we conducted a fourteen‐year (2002–2016) intraobserver error study. Motivated by the development of a large macromorphoscopic database―which will potentially utilize data collected in 2002―quantification of observer error, the impact of technological improvements in macromorphoscopic trait data collection and observer experience is necessary. To maximize comparisons between the two samples, ten macromorphoscopic traits were assessed. Results revealed three patterns of error relating to observer experience, the introduction of new technologies, and error inherent in the method. Overall, this study found the effect of error on macromorphoscopic trait analysis could be predicted and did not significantly impact their utility.     

Scanning Electron Microscopy–Energy‐Dispersive X‐Ray (SEM/EDX): A Rapid Diagnostic Tool to Aid the Identification of Burnt Bone and Contested Cremains

This study investigates the use of Scanning electron microscopy–energy‐dispersive X‐ray (SEM‐EDX) as a diagnostic tool for the determination of the osseous origin of samples subjected to different temperatures. Sheep (Ovis aries) ribs of two experimental groups (fleshed and defleshed) were burned at temperatures of between 100°C and 1100°C in 100°C increments and subsequently analyzed with the SEM‐EDX to determine the atomic percentage of present elements. Three‐factor ANOVA analysis showed that neither the exposure temperature, nor whether the burning occurred with or without soft tissue present had any significant influence on the bone's overall elemental makeup (p > 0.05). The Ca/P ratio remained in the osseous typical range of between 1.6 and 2.58 in all analyzed samples. This demonstrates that even faced with high temperatures, the overall gross elemental content and atomic percentage of elements in bone remain stable, creating a unique “fingerprint” for osseous material, even after exposure to extreme conditions.     

An open trial of an anger management treatment in a correctional facility: preliminary effectiveness and predictors of response

Despite the prevalence of anger management programs in correctional settings, there is mixed support for their effectiveness, and little is known about who benefits most. This preliminary study aimed to (1) evaluate the effectiveness of anger management for inmates, and (2) examine baseline psychopathology and midtreatment variables as response predictors. Participants were 30 incarcerated men undergoing 12-session anger management groups. Post-intervention, inmate-reported anger, and disciplinary actions decreased. Increased reported emotion regulation strategies predicted anger reduction.     

Exploitation of the Ultraviolet Properties and Machine Cut Edges of Paper to Associate and Sequence Sheets in a Ream

Previously unreported line patterns visible under ultraviolet light were observed on a proportion of plain white A4 printer/copier paper from different manufacturers. These Ultraviolet Line Patterns (UVLPs) usually appear as stripes down the vertical length of the paper. Typically, the UVLPs were found to “repeat” through the ream in a predictable way, while also changing. It is postulated that the repeating nature of the UVLPs is a result of the way that paper is manufactured. This leads to the ability to sequence the sheets compared to their original source paper. Even in the absence of UVLPs, it is possible to use our observation of the manufacturing process to anticipate the order of several sheets of paper and conclusively associate them, in some cases, by physically fitting their machine cut edges and crossing paper fibers. Such a novel approach to examining questioned documents would be highly useful in forensic casework.     

Court Sentencing Patterns for Environmental Crimes: Is There a “Green” Gap in Punishment?

Objectives

This study examines sentencing patterns for environmental crimes and tests the assumption that “green” offenders receive more lenient treatment from criminal courts than non-environmental offenders.

Methods

We present two sets of analyses. First, we present an empirical portrait of environmental felony offenses convicted in a single state (Florida) over a fifteen-year period and the resulting criminal sanctions. Second, we use a precision matching analysis to assess whether environmental offenders receive more lenient treatment when compared to non-environmental offenders with the same characteristics and offense severity scores.

Results

Findings indicate that an overall small percentage of felony convictions in state courts stem from environmental crimes. We also find that punishments for environmental crimes are more lenient than sanctions assigned to comparable non-environmental offenses when the environmental crime is ecological, but that punishments are sometimes harsher when the environmental crime involves animals.

Conclusions

The findings provide general support for the argument that courts and other formal institutions of social control treat environmental crimes more leniently than non-environmental crimes. This paper also raises important questions about citizen and state actors’ perceptions of crimes against the environment and, more generally, about the ways in which theories of court sentencing behaviors apply to environmental crime sanctioning decisions.

     

A new method for the recovery and evidential comparison of footwear impressions using 3D structured light scanning

Footwear impressions are one of the most common forms of evidence to be found at a crime scene, and can potentially offer the investigator a wealth of intelligence. Our aim is to highlight a new and improved technique for the recovery of footwear impressions, using three-dimensional structured light scanning. Results from this preliminary study demonstrate that this new approach is non-destructive, safe to use and is fast, reliable and accurate. Further, since this is a digital method, there is also the option of digital comparison between items of footwear and footwear impressions, and an increased ability to share recovered footwear impressions between forensic staff thus speeding up the investigation.     

Contextual information management: An example of independent-checking in the review of laboratory-based bloodstain pattern analysis

This article describes a New Zealand forensic agency's contextual information management protocol for bloodstain pattern evidence examined in the laboratory. In an effort to create a protocol that would have minimal impact on current work-flow, while still effectively removing task-irrelevant contextual information, the protocol was designed following an in-depth consultation with management and forensic staff. The resulting design was for a protocol of independent-checking (i.e. blind peer-review) where the checker's interpretation of the evidence is conducted in the absence of case information and the original examiner's notes or interpretation(s). At the conclusion of a ten-case trial period, there was widespread agreement that the protocol had minimal impact on the number of people required, the cost, or the time to complete an item examination. The agency is now looking to adopt the protocol into standard operating procedures and in some cases the protocol has been extended to cover other laboratory-based examinations (e.g. fabric damage, shoeprint examination, and physical fits). The protocol developed during this trial provides a useful example for agencies seeking to adopt contextual information management into their workflow.     

Pampered or pariah: does animal type influence the interaction between animal attitude and empathy?

ABSTRACT

Research into the interaction between deliberate harm of animals and potential risk for human directed violence has burgeoned in the past two decades. In light of an underlying premise that attitudes are predictive of behaviour, a number of researchers have examined demographic and personality variables that affect attitudes to, and by extrapolation behaviours towards, animals. One particularly active topic of research in this area is the potential relation between human-directed empathy and attitudes to animals, with researchers consistently finding that those with higher human-directed empathy scores tend to hold more pro-animal welfare attitudes. The current study adds to this literature by evaluating the effect of different animal types (Pet, Pest or Profit) in this overall animal attitude/human-directed empathy relationship with a large (n?=?1606), community-based, Australian sample. As anticipated, attitudes towards animals in the Pet category were significantly more pro-welfare than for either Pest or Profit animals and women indicated more pro-welfare attitudes across all three than men. The strength and significance of the relation between human-directed empathy and attitudes to animals varied across Pet, Pest and Profit animal categories and affective vs cognitive empathy. The strongest correlation was found between Pet and the Empathic Concern subscale of the Davis Interpersonal Reactivity Index. The implications of these differences for the previously observed link between attitudes to animals and empathy, humane education and future research directions are discussed.     

Economic Growth,Regime Insecurity,and Military Strategy: Explaining the Rise of Noncombat Operations in China

Abstract

Although China's armed forces have yet to complete its ambitious modernization program, its military strategy has begun to emphasize the ability to conduct noncombat operations such as disaster relief and peacekeeping in addition to traditional war fighting. This new component of China's military strategy is best explained by an unexpected relationship between economic growth and regime security. Although growth is key to the legitimacy of leaders in developing countries, it also creates new sources of domestic unrest and increases the vulnerability of the economy to external shocks, both of which, if unchecked, can harm future growth. As a result, developing countries such as China may use their armed forces to maintain political stability and provide services that the state lacks, such as emergency disaster relief. These conclusions are based on original data from China.
