The Effect of Time on Bone Fluorescence: Implications for Using Alternate Light Sources to Search for Skeletal Remains

Bones fluoresce when exposed to certain wavelengths of shortwave light, and this property can be useful in locating and sorting skeletal remains in forensic contexts. The proteins in bone collagen are largely responsible for its fluorescent properties, but these proteins degrade and denature over time. This study examined the fluorescence of bones from four temporal groups (recent, semi‐recent, ancient, and historic) ranging from 0 to 1064 years before present. Specimens were photographed under 490 nm wavelength light, and fluorescence was quantified by converting intensity to a gray scale value based on the RGB color model using ImageJ^® software. Significant (p < 0.05) differences were found in mean fluorescence between all four temporal groups, and a 0.324 coefficient of correlation indicates a significant (inverse) relationship between fluorescence and time. Bone fluorescence decreases with time, but some fluorescence is retained even in older samples. Fluorescence can therefore be reliably used in many modern skeletal remains searches.     

Effects of Aluminum Foil Packaging on Elemental Analysis of Bone,

Burned skeletal material is often very fragile and at high risk for fragmentation during packaging and transportation. One method that has been suggested to protect bones in these cases is to carefully wrap them in aluminum foil. Traces of aluminum, however, are known to transfer from foil packaging materials to food products. If such transfer occurs between aluminum foil and bones, it could interfere with subsequent chemical, elemental and isotopic analyses, which are becoming more common in forensic anthropological investigations. This study examined aluminum levels in bones prior to and following the use of aluminum foil packaging and storage for a 6‐week period. Results indicate no significant change in the detected levels of aluminum (p > 0.05), even when packaged in compromised foil and exposed to elevated temperatures. Aluminum foil can therefore continue to be recommended as a packaging medium without affecting subsequent chemical examinations.     

Criminal Careers in Cyberspace: Examining Website Failure within Child Exploitation Networks

Publically accessible, illegal, websites represent an additional challenge for control agencies, but also an opportunity for researchers to monitor, in real time, changes in criminal careers. Using a repeated measures design, we examine evolution in the networks that form around child exploitation (CE) websites, over a period of 60 weeks, and determine which criminal career dimensions predict website failure. Network data were collected using a custom-designed web-crawler. Baseline survival rates were compared to networks surrounding (legal) sexuality and sports websites. Websites containing CE material were no more likely to fail than comparisons. Cox regression analyses suggest that increased volumes of CE code words and images are associated with premature failure. Websites that are more popular have higher odds of survival. We show that traditional criminal career dimensions can be transferred to the context of online CE and constitute some of the key determinants of an interrupted career.     

Institutions,distributional concerns,and public sector reform

Abstract. As in otherWestern countries, a wave of reform has swept the Danish public sector. The record of these reforms is mixed and paradoxical; an ambiguous delegation of executive authority and radical privatization have been successfully implemented, while other measures, especially contracting out and user democracy or the introduction of greater choice, turn out to have failed. The paper argues that this experience offers two general lessons. First, shortterm costs and benefits are decisive to those who enact and implement public sector reform. Second, institutional factors specific to each type of reorganization have a major impact on the political distribution of costs and benefits.     

Bilateral Asymmetry of Nutrient Foramen Position in Forearm Bones: Implications for its Use in Sorting Commingled Remains

Commingling is frequently encountered in cases examined by the Committee on Missing Persons in Cyprus, and pair‐matching is routinely used as a preliminary segregation method. Here we examine the degree of bilateral asymmetry in nutrient foramen position of the radius and ulna to determine whether nutrient foramen position may be useful in visual and/or ostetometric pair‐matching. Differences in nutrient foramen position between left‐right pairs from the same individual were compared with differences in nutrient foramen position between different individuals. Bilateral asymmetry in nutrient foramen position was found to be high, indicating that it is not a reliable trait for pair‐matching. Bilateral asymmetry and between‐person variation were found to differ between the two bones examined, suggesting that nutrient foramen position in other long bones should also be tested.     

Parenting in Emerging Adulthood: An Examination of Parenting Clusters and Correlates

The changing nature of the transition to adulthood in western societies, such as the United States, may be extending the length of time parents are engaged in “parenting” activities. However, little is known about different approaches parents take in their interactions with their emerging-adult children. Hence, this study attempted to identify different clusters of parents based on the extent to which they exhibited both extremes of control (psychological control, punishment, verbal hostility, indulgence) and responsiveness (knowledge, warmth, induction, autonomy granting), and to examine how combinations of parenting were related to emerging adult children’s relational and individual outcomes (e.g. parent–child relationship quality, drinking, self-worth, depression). The data were collected from 403 emerging adults (M age = 19.89, SD = 1.78, range = 18–26, 62% female) and at least one of their parents (287 fathers and 317 mothers). Eighty-four percent of participants reported being European American, 6% Asian American, 4% African American, 3% Latino, and 4% reported being of other ethnicities. Data were analyzed using hierarchical cluster analysis, separately for mothers and fathers, and identified three similar clusters of parents which we labeled as uninvolved (low on all aspects of parenting), controlling-indulgent (high on both extremes of control and low on all aspects of responsiveness), and authoritative (high on responsiveness and low on control). A fourth cluster was identified for both mothers and fathers and was labeled as inconsistent for mothers (mothers were above the mean on both extremes of control and on responsiveness) and average for fathers (fathers were at the mean on all eight aspects of parenting). The discussion focuses on how each of these clusters effectively distinguished between child outcomes.     

The Reliability of Visually Comparing Small Frontal Sinuses*

Abstract: Several studies have investigated frontal sinus comparison for personal identification. One study addressed the statistical reliability of correct identification using automated digital methods and resulted in a 96% accuracy rate. Missed matches with the digital methods generally involved small, less featured sinuses. This study investigates the hypothesis that human examiners may be able to more accurately identify correct matches than digital methods, even when the comparisons involve small frontal sinuses. Participants were provided two sets of 28 radiographs and were instructed to identify matching radiographs and list the radiographs that did not have a corresponding match. Overall, error rates were low, with correct associations identified at a rate of 0.983. No incorrect associations (“false positives”) were made. Correct association rates were highest among participants “experienced” examining radiographs. Results support previous assertions that frontal sinus radiographs are a reliable means of personal identification even when the frontal sinuses are small.     

International Prosecution and National Bureaucracy: The Contest to Define International Practices Within the Danish Prosecution Service

This article explores how international ideals and practices of law enforcement come into conflict with national bureaucracies. Drawing on original interviews, the investigation demonstrates how the competition to define the role of international prosecution impacted career strategies as well as the actual administration of criminal law within the Danish Prosecution Service (DPS). The analysis shows that this competition is embodied in two competing groups of prosecutors situated in a wider national bureaucracy—itself subject to transformations that affect the very stakes of the contest to define the international. While the institutionalists build careers closely attuned to the systemic and increasingly lean‐management‐inspired requirements of the DPS, the dissident and consequently unsettled position of the activists leads them to craft alternative career strategies closely related to the emergence of new international fields of criminal law.     

Welfare Administration Reform Between Coordination and Specialization

This article identifies transboundary coordination practices and related modes of specialization in welfare administration reforms. We describe how the 2005 reform of the welfare administration in Norway started as a process of integration involving merger and partnership, but later, following the 2008 reorganization, introduced re-centralization and re-specialization. The main research questions are how we can explain this change of administrative reform? Why was the integrative administrative reform not sustainable and reorganization through re-specialization seen as a better answer to the “wicked issues” of welfare services? To answer these questions we apply a structural-instrumental perspective and a cultural-institutional perspective.     

Public Service Motivation: A Test of the Job Attraction–Selection–Attrition Model

ABSTRACT

Public service motivation (PSM) research suggests that PSM influences employee sector choice, yet relatively little research examines how time moderates this relationship. In this research we examine public service motivation among private and public sector lawyers. Using survey data that measure sector of employment at multiple time periods, we investigate the stability of the relationship between individual reward orientations and sector employment choice over time. Our findings suggest that while PSM may not clearly predict the employment sector of a respondent's first job, it does increase the likelihood that a respondent's subsequent job is in the public sector.
