Age Estimation by Amino Acid Racemization in Human Teeth

Abstract: When an unidentified body is found, it is essential to establish the personal identity of the body in addition to investigating the cause of death. Identification is one of the most important functions of forensic dentistry. Fingerprint, dental, and DNA analysis can be used to accurately identify a body. However, if no information is available for identification, age estimation can contribute to the resolution of a case. The authors have been using aspartic acid racemization rates in dentin (D‐aspartic acid/L ‐ aspartic acid : D/L Asp) as an index for age estimation and have obtained satisfactory results. We report five cases of age estimation using the racemization method. In all five cases, estimated ages were accurate within a range ±3 years. We conclude that the racemization method is a reliable and practical method for estimating age.     

Results of the 2008 Colombian paternity testing quality control exercise

The Reference National Laboratory, Genes Ltda, designated by the Commission of Accreditation and Alertness created by Law 721 of 2001 of Republic of Colombia, organized and coordinated the Quality Control Exercise of 2008 for laboratories undertaking paternity and maternity tests with DNA markers. The Quality Control Exercise included both practical and theoretical exercises. For the practical exercise, three blood samples in FTA Classic Card were sent to each participating laboratory to be genotyped for DNA markers using the routine methodologies in their laboratories. For the theoretical exercise, it was asked to the participating laboratories to calculate the partial and final paternity indexes based on two genetic profiles of an alleged biological father and his son. Allele frequencies were made available to the participants, as well as Y chromosome haplotype database. A total of 12 laboratories have participated with data from 57 STRs, including autosomal and sex chromosome markers. Consensus was found in 37 STRs, 21 in autosomes and 16 Y chromosome linked. The rate of reporting errors was 3.1% (concentrated in just one laboratory). The theoretical exercise had consensus.     

Japan＇s ＂unsettling＂ past： Article 11 of San Francisco Peace Treaty and its ramlncatlons

Article 11 of the Treaty of Peace with Japan （San Francisco Peace Treaty） has become a rallying point for some activists and historians in their endeavor to have Japan recognize its ＂war responsibility＂ and redress its ＂unsettled past＂. The provision stipulates Japan＇s acceptance of the ＂judgments of the International Military Tribunal for the Far East and of other Allied War Crimes Courts both within and outside Japan＂. The wording of this provision, which is ambiguous enough to leave a room for its re-interpretation later, was a result of a compromise among the World War lI Allies. Yet, neither archival investigation of the article＇s drafting process nor a survey of the opinions of U.S. legal experts in the public international did not prove the validity of the revisionist thesis. Nevertheless, the treaties Japan signed with its former colony （Korea） and belligerent （China） left the settlement of war-related issues obscure, creating a leeway for initiating later controversies. The end of the Cold War heralded the re-evaluation of World War I1 settlements. The subsequently created agitated environment surrounding the historical discussion of Japan＇s so-called ＂unsettled＂ past has been ＂unsettling＂ enough to prevent the Japanese leaders from establishing a uniform interpretation of Article l l, and has added impetus to the movements pressuring Japan to recognize its ＂war responsibility＂. Although interested parties have so far cited Article 11 mainly to demand ＂inaction＂ from Japan, such as to discourage Japanese political leaders from visiting the Yasukuni Shrine, there is a growing indication that some may well utilize it to demand Japan＇s ＂action＂--to pay indemnities to the victims of Japan＇s alleged atrocities through various forms of redress movements.     

Turkey’s Public Administration Today: An Overview and Appraisal

ABSTRACT

This study overviews and appraises Turkey’s contemporary public administration system. Its prominent characterizing features are discussed, with an emphasis on both the achievements and problem areas. Turkey has a long history of strong traditional bureaucratic practices and culture, from which its contemporary public administration system has emerged since the Republic was established almost a century ago. Despite its many achievements, public administration has its problems, generally the product of conflicts between tradition and modernity. Due emphasis should, however, be given to addressing the challenges of its over-politicization, strengthening governance practices, enhancing the human factor, and instituting further modern administrative reforms.     

The Relative Influence of Different Domains of Social Connectedness on Self-Directed Violence in Adolescence

Previous research has linked greater social connectedness with a lowered risk of self-directed violence among adolescents. However, few studies have analyzed the comparative strength of different domains of connectedness (e.g., family, peers and school) to determine where limited resources might best be focused. Data to address that gap were taken from the Centers for Disease Control and Prevention’s Student Health and Safety Survey, administered to 4,131 7th–12th graders (51.5% female; 43.8% Hispanic; 22.6% African American or Black). Logistic regressions (controlling for age, gender, race/ethnicity, family structure, academic performance, and depressive symptoms) suggest that family connectedness was a stronger predictor than connectedness to peers, school, or adults at school for non-suicidal self-harm, suicidal ideation, suicide plans, and non-fatal suicidal behavior. In some analyses, peer connectedness was unexpectedly a risk factor. Results have implications for prevention of suicide in adolescence, especially in the context of the current trend towards school-based prevention programs.     

Diagnostic criteria for postbullying disorder: A phenomenological research design of bullying victims

This study aimed to investigate the diagnostic criteria for postbullying disorder, which enable the persons who provide therapy services for bullying victims, because until now, there are no criteria to help clinicians diagnose postbullying disorder. This study employed phenomenological research design. Purposive sampling was adopted to sample six university students who are experiencing the bullying behavior from their colleagues in the university campus. The results revealed that there are eight criteria for diagnosing postbullying disorder among victims. These are trauma exposure, symptoms of penetration, avoidance, perception and negative emotions, self‐destructive behavior, dysfunction due to symptoms, duration (1 month or more) of symptoms, and the criteria that the bullying symptoms cannot be attributed to the use of substances or drugs of another medical conditions. Results shed new light on the diagnostic criteria for postbullying disorder and proved the usefulness of these criteria in understanding the development of the postbullying symptoms among victims. These findings enable schools and universities to plan psychotherapy interventions for victims.

A Longitudinal Investigation of Cognitive Self-schemas across Adolescent Development

Research in developmental psychology highlights youth’s self-schemas as one possible pathway to improve adolescents’ functioning and promote positive developmental outcomes. Despite this, the trajectory of positive and negative self-schemas is relatively understudied. This study addresses this limitation by empirically examining the trajectory of self-schemas in a community sample of 623 youth (M?=?13.04 years; 54% female; 49% African American, 4% Biracial, 47% European American) who were followed over a seven-year period. Caregivers completed measures of parenting practices, maternal rumination and negative inferential style, and adolescents completed a computerized behavioral task assessing self-schemas (i.e., mental frameworks that guide attention, interpretation, and memory of one’s experiences). Multilevel growth curve modeling results demonstrated a quadratic slope for negative self-schemas and no mean-level change for positive self-schemas. These trajectories did not vary by gender or racial group. However, parenting factors differentially influenced the trajectories. Specifically, higher levels of parental involvement at baseline, or an active interest and engagement in a child’s experiences and activities, related to lower levels of negative self-schemas during adolescence. Additionally, higher levels of parental rumination and parental negative control at baseline related to lower levels of youth positive self-schemas at baseline. These findings contribute to models of youth cognitive development.
