Calcium and Phosphorus Detection Using Benchtop Versus Handheld X‐ray Fluorescence Spectrometers

Elemental analysis of calcium (Ca) and phosphorus (P) has been shown to be useful in differentiating skeletal and nonskeletal material. X‐ray fluorescence spectrometry (XRF) is an attractive, nondestructive technique for forensic anthropologists, and the development of portable XRF instrumentation is promising for field applications. This study examines the performance of handheld XRF instrumentation operated in air compared to a traditional benchtop XRF device that has the ability to control the analysis atmosphere. Both instruments can be used to effectively distinguish skeletal from nonskeletal remains. However, as the measurement atmosphere affects detection levels for calcium and phosphorus, Ca/P ratios obtained from the instruments and analysis conditions were found to differ significantly, with analyses conducted in air showing significantly lower phosphorus detection. Consequently, comparison of Ca/P ratios to conclude skeletal versus nonskeletal origin must be based on data collected under similar analysis conditions.     

Family Transitions and Later Delinquency and Drug Use

Changes in the family structure can be very disruptive to adolescents who live in those families. This article examines the impact of the number of family transitions on delinquent and drug-using behavior. Specifically, the effect of family transitions is hypothesized to be mediated by problems within the family, school, and peer settings. A sample of 646 boys (73%) and girls (27%) taken from a longitudinal panel study of high-risk adolescents are used to examine these hypotheses. For girls, little support is found for the direct or the indirect effect of family transitions on delinquent behavior or drug use. For boys, however, both forms of problem behavior are influenced by family transitions directly and indirectly through changes in, and problems with, peer associations. The findings suggest that during times of family turmoil, the friendship network of adolescent male children is also disrupted, leading to an increase in associations with delinquent others and, in turn, an increase in problematic behaviors.

Federal Financial Reporting: Some views of R.K. Mautz

A number of proposals would apply Generally Accepted Accounting Principles (GAAP), as developed for reporting the financial performance of for-profits, to federal financial reporting and budget accounting. Critics of these proposals include R.K. Mautz, a distinguished professor of accountancy. This article summarizes some of Mautz's conceptual objections to the use of private GAAP by not-for-profits and indicates his preferred approach to improved financial reporting by government.     

Heifer International: Growing a learning organisation

Heifer International (HI) has been applying participatory approaches to rural development for nearly 60 years. Organisationally, HI focuses on building the capacity of its country programmes and NGO partners to work independently toward a unifying mission. An open structure allows HI to validate and incorporate the rich and diverse experience of its project holders and country programme offices into organisational planning and daily operations. This article analyses three recent HI initiatives which incorporate deliberate processes to facilitate organisational learning. It outlines different strategies that HI uses to institutionalise learning without imposing limitations on it.     

Desistance as a Developmental Process: A Comparison of Static and Dynamic Approaches

New research in the field of developmental criminology has led researchers to reconceptualize desistance as a behavioral process that unfolds over the life course. This approach puts more emphasis on the pathways by which people reach the state of non-offending, and less emphasis on the state of non-offending itself. This reconceptualization has implications for how we measure desistance in longi-tudinal data. In this paper, we suggest that the traditional measurement approach is inconsistent with this view, and we present an alternative measurement approach based on the premises of developmental criminology. Although not perfect, we argue that the dynamic measure better describes the key elements of the process of desistance. Both approaches are implemented using data from the Rochester Youth Development Study, a longitudinal study of youthful offenders. We demon-strate that the two approaches identify different people as desistors. Moreover, we argue that the dynamic definition of desistance has more promise for providing insight into the changes that are the behavioral focus of the desistance process.     

Investigating Friendship Quality: An Exploration of Self-Control and Social Control Theories’ Friendship Hypotheses

While associations with deviant peers are well understood to impact individual development, less is understood about the relationship between friendship quality and delinquency. Two criminological theories-social control theory and self-control theory-are able to offer an explanation for the latter relationship. Social control and self-control theories both premise that delinquents will have largely fractured, weak, and "cold and brittle" friendships. This study investigates how variations in perceptions of friendship quality are related to the delinquency, maternal attachment, school attachment, and self-control levels of both a participant and his/her close friend. To explore these relationships, we use a diverse (14% black; 18% Hispanic; 9% Asian) sample of 2,154 emerging adults within 1,077 friendship pairs (66% female). In each dyad, both members perceived the friendship's quality and reported personal markers of delinquency, social bonds, and self-control. Several series of multilevel models are estimated that regress each participant's friendship quality perception onto the participant's and their friend's delinquency, attachments, self-control, and demographic characteristics. Results show that delinquents have as intense, or more intense, friendships as non-delinquents. However, low levels of both actor and partner attachments and self-control are independently related to low friendship quality, and this is especially true for self-control. Supplemental analyses demonstrate that the effect of self-control on friendship quality may be reduced when individuals in dyads are delinquent. In conclusion, studies that address friendship quality without including characteristics of multiple members of the friendship are only capturing part of one's estimate of friendship quality.
