A simulation for exploring the effects of the "trait list" method's subjectivity on consistency and accuracy of ancestry estimations

The nonmetric "trait list" methodology is widely used for estimating ancestry of skeletal remains. However, the effects of the method's embedded subjectivity on subsequent accuracy and consistency are largely unknown. We develop a mathematical simulation to test whether variation in the application of the "trait list" method alters the ancestry estimation for a given case. Our simulation explores how variations in (i) trait selection, (ii) number of traits employed, and (iii) ancestry choice thresholds affect the ancestry estimation of an unidentified skeleton. Using two temporally and geographically diverse samples, the simulation demonstrates that trait selection, trait quantity, threshold choices, and the exclusion of high-frequency traits had minimal effect on estimation of general ancestry. For all data sets and Runs, Accuracy(AS) was maintained above 90%. The authors close with a discussion on the logistical issues present when choosing traits, and how to avoid ancestry bias.     

Community-level impacts of temperature on urban street robbery

Purpose

Conduct the first empirical intra-urban examination of community-level connections between street robbery and temperature. Examine whether community socioeconomic status (SES) and crime-relevant land uses strengthen or weaken the temperature impact. A theoretical framework relying on routine activity theory, crime pattern theory, and resident-based control dynamics organized predictions.

Data and methods

For Philadelphia census tracts (n = 381), monthly street robbery counts and temperature data for 36 consecutive months were combined with census and land use data, and analyzed with multilevel models.

Results

Community robbery counts were higher when temperatures were higher, and in lower SES communities. In support of previous work with property crime, but in contrast to previous work with assault, the effects of temperature were stronger in higher SES communities. In support of the integrated model, commercial land use prevalence and subway stations were associated with heightened temperature impacts on robbery.

Conclusions

Community-level fixed and random effects of temperature on urban robbery counts persist when controlling for land use and community structure; further, the random effects depend in part on both. There are implications for understanding indigenous guardianship or informal resident-based place management dynamics, and for planning seasonal police deployments.     

Supreme Court to Hear Landmark Case on Climate Change Emissions: Judgment Day Comes in Global Warming Litigation

The Supreme Court has historically been reluctant to involve itself in environmental matters, especially those relating to the regulation of releases or emissions of harmful substances. The court has typically been content to allow the legislative branch to fashion appropriate regulations to address environmental issues and for the executive branch to enforce those regulations. The acceptance of certiorari in the Second Circuit's Connecticut v. AEP case was a surprise because it not only involves environmental regulation, but also the common law applicable to public nuisance actions seeking redress for climate change damage allegedly caused by emissions of greenhouse gases (GHGs). The AEP case is shaping up to be a blockbuster in the climate change debate in the United States, and the decision could have broad repercussions in not only future litigation involving climate change, but also GHG legislation and the insurance available to address damage due to weather-related events.     

EARLY INTERVENTION IN NEW ZEALAND FAMILY COURT CASES

In April 2010 the New Zealand Family Court introduced the National Early Intervention Process (NEIP) to diversify its previous unitary dispute resolution pathway into two tracks (standard and urgent). A “triage” model is now in use to assess and assign cases appropriately. This article outlines the key milestones in the Family Court's 30‐year history which have led to this new initiative to reduce delays and help avoid the escalation of family conflicts over the care of children into bitter and intractable disputes. NEIP represents the most overarching reform of the Family Court since the Court's inception in 1981.     

Enduring neoliberalism in Alberta's oil sands: the troubling effects of private–public partnerships for First Nation and Métis communities

Changes in federal government relations with First Nations and Métis in Canada have been described as shifting over time, from fur trade colonialism, to welfare colonialism, to neoliberal partnerships. Acknowledging changes and continuities in Aboriginal peoples–state relations over time, this article examines the effects of recent policies that emphasize private–public partnerships for economic development on Indigenous communities in northern Alberta. We argue that while the term ‘partnership’ connotes equality, cooperation, and consensus, the actual workings of partnerships are anything but equal, and the effects include fragmentation, competition, and lack of overall accountability. These outcomes work against the needs and aspirations of Indigenous communities.     

The university technology transfer revolution in Saudi Arabia

This paper explains why and how a technology transfer revolution is taking place in Saudi Arabia to meet the mandate that Saudi Arabia become globally competitive as a knowledge-based innovative economy. The paper explains and identifies the new policies and institutions that have been introduced and developed to facilitate technology transfer and knowledge spillovers from the universities for commercialization and ultimately innovative activity and economic growth. The paper finds that a technology transfer revolution in Saudi Arabia is taking place, with the goal of leapfrogging from the factor-based stage of economic development to the innovation-based stage of economic development, while bypassing the intermediary efficiency-based stage of economic development.     

Exploring gender differences in dating violence/harassment prevention programming in middle schools: results from a randomized experiment

In this study, we randomly assigned 123 sixth and seventh grade classrooms from seven middle schools in the greater Cleveland area to one of two five-session curricula addressing gender violence/sexual harassment (GV/SH) or to a no-treatment control group. A baseline survey and two follow-up surveys were administered immediately after the treatment (Wave 2) and about six months post-treatment (Wave 3). In an earlier paper, we demonstrated the effectiveness of two approaches to youth GV/SH prevention programming (a fact-based, law and justice curriculum and an interaction-based curriculum). In this paper, we explored whether these largely positive findings remain for both girls and boys, including whether girls experience higher levels of GV/SH than boys. Most of our statistical models proved to be non-statistically significant. However, in 2 of our 48 victimization/perpetration (any violence, sexual violence and non-sexual violence) models (across two post-intervention follow-up points), we observed that the interventions reduced peer (male or female, non-dating partner) sexual violence victimization and reduced peer perpetration, but another outcome model indicated that the interventions increased dating perpetration. These mixed findings will need to be explored further in future research. Regarding our primary research question, we observed no statistically significant differences for the treatment multiplied by gender interaction terms for any of the perpetration or victimization outcome models, suggesting that the treatment had similar effects on girls and boys. However, we did observe that boys are more involved in violence than girls: both as victims and perpetrators. Boys experienced significantly more of three types of victimization from peers and dating partners compared to what girls experienced at the hands of their peers and dating partners. As perpetrators, boys committed more sexual victimization against peers (immediately post-intervention only) and more sexual victimization against dating partners than girls. The implications of these results are discussed.     

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.
