Calculation of percent shrinkage in human fetal diaphyseal lengths from fresh bone to carbonized and calcined bone using Petersohn and K?hler's data.

Calculation of age from fetal and newborn remains may be problematic, and when these remains are altered by maceration, decomposition or burning, age may be more difficult to discern. When soft tissue indicators are transformed, then two techniques exist for accurate age determination; dental development, which may prove difficult given the degree of tissue alteration; and appearance, size and fusion of ossification centers, including diaphyseal length, which may yield inaccurate ages if shrinkage is not accounted for. This study is undertaken to facilitate age calculation by systematically re-evaluating diaphyseal shrinkage and determine shrinkage rates from wet to carbonized states and wet to calcined states using Petersohn and K?hler's data, originally published in German and then published in Fazekas and Kósa (1978:362-369). Average shrinkage, standard deviation, minimum and maximum values are calculated for each diaphysis and then for all diaphyses between 4-10 lunar months (LM) and for newborns. Associated values for carbonized diaphyses are: 4 LM--32.50% +/- 12.12%; 5 LM--14.04% +/- 4.44%; 6 LM--6.78% +/- 1.06%; 7 LM--4.18% +/- 0.31%; 8 LM--3.47% +/- 0.42%; 9 LM--3.05% +/- 0.18%; 10 LM--2.46% +/- 0.67%; and in newborns 2.16% +/- 0.29%. Similar values for calcined diaphyses are: 4 LM--40.11% +/- 17.51%; 5 LM--18.29% +/- 4.42%; 6 LM--9.84% +/- 1.27%; 7 LM--9.82% +/- 0.51%; 8 LM--9.42% +/- 0.72%; 9 LM--9.45% +/- 0.33%; 10 LM--8.94% +/- 0.37%; and in newborns 8.96% +/- 0.49%. These findings suggest that percent shrinkage due to carbonization and calcination is greatest in the earliest age groups, decreasing substantially with advancing age. The rates of shrinkage, however, vary by the burning process utilized and age group studied. These general findings are similar to those of Petersohn and K?hler, yet specific values for percent shrinkage vary greatly from values cited in this analysis. These data provide a means to assess the degree of shrinkage that occurs for each diaphysis for each given age group.     

A Call to Action—The Essential Role of Advocacy

Editor's Note: The Perspectives featured in this issue of Public Administration Review were adapted from May 2016 commencement addresses: Anna Maria Chavez, the CEO of the Girl Scouts of the USA, spoke on the 12th at Arizona State University's College of Public Service and Community Solutions; Nancy Pelosi, the Democratic Leader in the United States House of Representatives spoke on the 7th at New York University's Wagner School of Public Service; and Tommy Thompson, the former Governor of Wisconsin and Secretary of Health & Human Services, spoke on the 15th at the University of Wisconsin's La Follette School of Public Affairs. These Perspectives reaffirm the highest principles of American public administration: that by and large, government is NOT the problem, and quite often indeed holds the solution; that effective and helpful public policy depends on informed expert opinion and research; and that those who enter public service should do so with a commitment to the notion that America best fulfills its promise when we seek the well‐being of all people, including the least fortunate. We chose these messages from among a wealth of commencement speeches because while they come from leaders with quite different political views, background, and experience, taken together they offer a coherent and inspiring call to public service.

Youth justice conferencing and indigenous over-representation in the Queensland juvenile justice system: a micro-simulation case study

Restorative justice conferencing for young offenders is firmly established in Australian juvenile justice, and legislated conferencing schemes are operating in all Australian states and territories. While there is some variation in the terms used to describe restorative justice conferences (e.g., family group conferencing, family conferencing, or youth justice conferencing), there is much more consistency in how the conferencing process is managed across Australian jurisdictions. In Queensland youth justice conferencing is a process that brings together an offender, the victim and their supporters to discuss the harm caused by the offending behaviour and provide the young person with an opportunity to take responsibility for his or her behaviour and make amends. This paper begins by briefly sketching the development of restorative justice conferencing in Queensland and describes the Juvenile Justice Simulation Model (JJSM), a micro-simulation model developed for criminal justice policy analysis in Queensland, Australia. We use this micro-simulation model to conduct an experimental exploration of the effects that youth justice conferencing has on system-wide outcomes for indigenous young people. The model simulates the impact of interventions up until 2011 on the number of finalised youth justice court appearances. Our results indicate that youth justice conferencing is unlikely to reduce the over-representation of indigenous young people in the juvenile justice system. The simulations demonstrated that, by the 2011, youth justice conferencing would result in a 12.5% decrease in finalised court appearances. Unfortunately, this decrease was more apparent for non-indigenous young people (13.7% decrease in court appearances) than for indigenous young people, who had a 10.5% decrease in court appearances. This differential impact of conferencing is due to the different court appearance profiles between indigenous and non-indigenous young offenders, with indigenous young people initiating offending at an earlier age and offending more frequently than non-indigenous young offenders.
