Thermal Imaging as a Lie Detection Tool at Airports

We tested the accuracy of thermal imaging as a lie detection tool in airport screening. Fifty-one passengers in an international airport departure hall told the truth or lied about their forthcoming trip in an interview. Their skin temperature was recorded via a thermal imaging camera. Liars’ skin temperature rose significantly during the interview, whereas truth tellers’ skin temperature remained constant. On the basis of these different patterns, 64% of truth tellers and 69% of liars were classified correctly. The interviewers made veracity judgements independently from the thermal recordings. The interviewers outperformed the thermal recordings and classified 72% of truth tellers and 77% of liars correctly. Accuracy rates based on the combination of thermal imaging scores and interviewers’ judgements were the same as accuracy rates based on interviewers’ judgements alone. Implications of the findings for the suitability of thermal imaging as a lie detection tool in airports are discussed.     

Identification of two fire victims by comparative nuclear DNA typing of skeletal remains and stored umbilical tissues

We describe here our collaborative efforts in identifying 2 fatalities of a fire disaster by using a variety of identification techniques. Postmortem findings in both cases were reinforced using Short Tandem Repeat (STR) DNA technology to establish with a high degree of certainty the identities of 2 child victims. STR markers used in the present study include HUMAMEL, HUMCSFIPO, HUMTHO1, HUMvWA, HUMFES/FPS, HUMF13A01, HUMFOLP23, D8S3O6, HUMFGA, and HUMTPOX. Unambiguous identification was made possible through matching DNA profiles generated from skeletal remains with those from umbilical tissues. These tissues were kept by their mothers in accordance with a Philippine tradition and were submitted for DNA analysis. Of the DNA profiles generated from exhumed bone samples of 21 child victims, comparison with the genetic profiles of children A and B obtained from umbilical tissues showed consistent DNA matches with remains 1756 and 1758, respectively.     

Reforming the World Health Organization: what influence do the BRICS wield?

The World Health Organization (WHO) is currently undergoing fundamental reform that is intended to impact its programmes and priority setting and its financial and governing structures. Within the reform debates, new relations of powers are emerging among traditional donors and emerging economies such as the ‘BRICS’: Brazil, Russia, India, China and South Africa. These five emerging economies have formally committed ‘to strengthen and legitimise the WHO as the coordinating authority in global health’ through the principle of multilateralism. In this paper, the results of a qualitative study – based on 21 key informant interviews – that seeks to better understand BRICS’ engagement in this organisation and the extent to which their action enables these countries to influence the reform process were presented. The results show that individual BRICS countries found natural pairings with each other on both particular elements of the reform, notably governance and WHO financing, and specific health issues. While numerous examples of individual BRICS countries seeking to raise the profile of specific health issues were found, some evidence of a coordinated effort to influence reform as a bloc was also found. Although this was largely limited to rhetorical announcements of support in formal Declarations and Communiqués, it nevertheless articulates a vision of the WHO as an organisation with a broad mandate delivered with sufficient, predictable funding.     

Longitudinal Bi-directional Relationships Between Sleep and Youth Substance Use

Despite the known deficits in sleep that occur during adolescence and the high prevalence of substance use behaviors among this group, relatively little research has explored how sleep and substance use may be causally related. The purpose of this study was to explore the longitudinal bi-directional relationships between sleep duration, sleep patterns and youth substance use behaviors. Participants included 704 mostly white (86.4?%) youth, 51?% female, with a baseline mean age of 14.7?years. Self-reported substance use behaviors included past month alcohol, cigarette, and marijuana use. Sleep measures included sleep duration on weekends and weekdays, total sleep, weekend oversleep, and weekend sleep delay. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between sleep and substance use adjusting for socio-demographic characteristics, pubertal status, body mass index z-score, and depressive symptoms. Cigarette use and weekend sleep were bi-directionally related as were marijuana use and total sleep. No other bi-directional associations were identified. However, alcohol use predicted shorter weekend oversleep and marijuana use predicted increased weekend sleep and weekend oversleep. Sleep patterns and duration also predicted adolescents' cigarette, alcohol, and marijuana use. Sleep, both patterns and duration, and substance use among youth are intertwined. Future research is needed to explore these bi-directional relationships, as well as other important contextual factors that may moderate these associations.     

Reliability of Craniofacial Superimposition Using Three‐Dimension Skull Model

Craniofacial superimposition is a technique potentially useful for the identification of unidentified human remains if a photo of the missing person is available. We have tested the reliability of the 2D‐3D computer‐aided nonautomatic superimposition techniques. Three‐dimension laser scans of five skulls and ten photographs were overlaid with an imaging software. The resulting superimpositions were evaluated using three methods: craniofacial landmarks, morphological features, and a combination of the two. A 3D model of each skull without its mandible was tested for superimposition; we also evaluated whether separating skulls by sex would increase correct identifications. Results show that the landmark method employing the entire skull is the more reliable one (5/5 correct identifications, 40% false positives [FP]), regardless of sex. However, the persistence of a high percentage of FP in all the methods evaluated indicates that these methods are unreliable for positive identification although the landmark‐only method could be useful for exclusion.     

The future of online social work education and Title IV-E child welfare stipends

ABSTRACT

In this concept paper, the authors explore online learning in social work and how IV-E education has been and will continue to be impacted. An empirical estimate of the national prevalence of online IV-E social work degree options is presented. Using Colorado as a case example, the authors share some of the opportunities and challenges presented by online education. Universities in Colorado have realized that online education connects rural and indigenous communities, reduces the need for students to relocate, and promotes a well-prepared, qualified child welfare workforce, but online options also challenge programs with localization issues. With connectivity increased and the physical location of students becoming less and less relevant, IV-E child welfare education providers need a proactive national dialogue to further assess the benefits and barriers to IV-E partnerships across state lines and the development of promising approaches in this area. The recruitment and retention of a well-educated and prepared child welfare workforce is critical for positive outcomes for children and families. Online social work education continues to grow nationwide. Now is the time for a national workgroup, including a broad group of stakeholders, to explore how the IV-E community will respond to online delivery of social work education.     

Optimal enforcement of competition policy: the commitments procedure under uncertainty

The introduction of a commitments procedure in EU antitrust policy (Article 9 of Council Regulation 1/2003) has entitled the the European Commission to extensively settle cases of alleged anticompetitive conduct. In this paper, we use a formal model of law enforcement to identify the optimal procedure to remedy cases in a context of partial legal uncertainty (Katsoulacos and Ulph in Eur J Law Econ 41(2):255–282, 2016). We discuss in particular the merits of a policy of selective commitments where firms either take strong commitments or are investigated under the standard infringement procedure.
