Body Morph: Feasibility Testing of an Interactive CD-ROM to Teach Young Adolescents about Puberty

The aim of this pilot study was to examine the feasibility of an interactive computer program among 34 sixth and seventh grade children and to assess the potential for knowledge acquisition about puberty. Based on a developmental self-esteem approach to teach children about their bodies, the Body Morph program was designed to maximize the educational experience by: (1) tailoring puberty information to boys or girls, and (2) creating a confidential experience. Preliminary results indicated that students significantly improved their knowledge about puberty after using the program. Satisfaction among boys and girls for this type of educational approach suggests that it is a compelling format from which to learn about puberty.This research project was funded with the support of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) 1R43DK061269-01A2 to develop an educational computer program to improve body image in middle schoolers.     

A comprehensive ATR-FTIR spectroscopic analysis for the identification and differentiation of lip balms

Lip balm may be encountered as physical evidence in cases involving sexual assaults, homicides, and kidnappings. Lip balm can be used as corroborative evidence by providing a potential link between the victim, accused, and the crime scene. For lip balms to be used as evidence, it is important to understand the diversity and their aging process under different conditions. Therefore, in this study, ATR-FTIR spectroscopy in conjunction with chemometric tools such as principal component analysis (PCA) and linear discriminant analysis (LDA) has been used for the objective identification and differentiation of 20 brands of lip balms. Moreover, lip balms on different substrates and wearing effects over time were also investigated. The results show that the PCA-LDA training accuracy was 92.5%, whereas the validation accuracy comes out to be 83.33%. A blind study using pristine samples was also performed which resulted in 80% PCA-LDA accuracy. PCA-LDA prediction of samples on various substrates showed a higher chemometric prediction accuracy for nonporous substrates (glass, plastic, and steel), than for porous substrates (cotton cloth, cotton swab stick, dry tissue paper, and white paper) for samples kept in room temperature and under sunlight for 15 days. The substrate study showed that the samples from various substrates could effectively generate respective spectra which can help in brand-level identification even after several days. The present method demonstrates a potential for lip balm samples to be used in forensic casework applications.     

The role of DNA in criminal indictments in Israel

In their investigations of criminal cases, law enforcement agencies rely heavily on forensic evidence. Numerous studies have examined the scientific and technological advancements of DNA testing, but little evidence exists on how the availability of DNA evidence influences prosecutors' decisions to move cases forward in the criminal justice system. We created a new database by juxtaposing data from the Forensics Division of the Israel Police, which recorded the presence (or not) of DNA profiles in criminal cases (n = 9862), and data on the indictment decision for each case (2008–2019). Rates of indictments are computed for each case, and trend lines are used to present variations in the rates of indictment decisions with and without DNA profiles. Approximately 15% of all criminal cases without DNA presented to the prosecutor's office are subsequently prosecuted, compared with nearly 55% of cases with DNA profiles. The presence of DNA evidence influences the prosecutor's decision to move a case forward in the criminal justice system. Utilizing a scientific approach to prosecute offenders is a welcome development; however, DNA evidence is not infallible, and caution must be exercised in regard to DNA's overuse in the legal system.     

A systematic approach to improve downstream single-cell analysis for the DEPArray™ technology

Most commercially available STR amplification kits have never been fully validated for low template DNA analysis, highlighting the need for testing different PCR kits and conditions for improving single-cell profiling. Here, current strategies rely mainly on adjusting PCR cycle number and analytical threshold settings, with a strong preference for using 30 amplification cycles and thresholds at 30–150 RFU for allele detection. This study aimed to (1) determine appropriate conditions for obtaining informative profiles utilizing a dilution series, and (2) test the outcome on single cells using the DEPArray™ technology. Four routinely applied forensic STR kits were compared by using three different amplification volumes and DNA dilutions down to 3.0 pg, while two well-performing kits were used for single/pooled leucocyte and sperm cell genotyping. Besides reduced costs, the results demonstrate that a 50%–75% PCR volume reduction was beneficial for peak height evaluation. However, this was counteracted by an increased artifact generation in diluted DNA volumes. Regarding profile completeness, the advantage of volume reduction was only prominent in samples processed with Fusion 6C. For single and pooled cells, ESIFast and NGMDetect provided a solid basis for consensus profiling regarding locus failure, although locus dropouts were generally observed as stochastic events. Amplification volume of 12.5 μL was confirmed as appropriate in terms of peak heights and stutter frequencies, with increased stutter peaks being the main artifact in single-cell profiles. Limitations associated with these analyses are discussed, providing a solid foundation for further studies on low template DNA.     

Embutramide,a Component of Tanax®(T‐61) as a New Drug of Abuse?

Tanax^®(T‐61) is a euthanasia solution commonly used in veterinary medicine in Europe. It consists of three active components: embutramide, mebezonium iodide, and tetracaine hydrochloride. Human consumption of Tanax^®(T‐61) is usually associated with suicide attempts. In our 15‐year‐long practice, embutramide was detected only three times but within a short period. First, it was found in the urine of a 42‐year‐old veterinarian, and the other two observations were made in a 16‐year‐old young man. Urine samples were analyzed using Shimadzu Prominence TOX.I.S.II. HPLC–DAD system with online SPE extraction system. Both of the two patients denied any intention to die. These cases show that this veterinary drug may also be considered as potential drugs of abuse.     

Zur analogen Anwendung des § 29 Abs 2 MRG auf unbefristete Mietverträge mit Kündigungsverzicht des Mieters

Der OGH hat nunmehr bereits in zwei Entscheidungen die Auffassung vertreten, dass § 29 Abs 2 MRG nicht auf Wohnungsmietverh?ltnisse anwendbar ist, die zwar auf unbestimmte Zeit geschlossen werden, aber auf bestimmte Zeit mit einem Kündigungsverzicht des Mieters versehen sind. Der nachfolgende Beitrag erbringt den Nachweis, dass diese Auffassung mit dem Anliegen nicht vereinbar ist, das § 29 Abs 2 MRG verfolgt.     

Regionalisation as a Driving Force of EU Widening: Recovering from the EU ‘Carrot Crisis’ in the ‘East’

This article focuses on the ‘globalisation-cum-regionalisation’ process in the European Union that has led to the emergence of functional macro-regions. It provides first a classification of regionalisation, and describes the organisational and mental barriers of the European Neighbourhood Policy (ENP). The second part traces the shift of the ENP from the South to the East that has also activated the EU's pre-accession policy in the West Balkan region and the Eastern Partnership programme. Finally, it argues that the Baltic Strategy and the Danube Strategy as functional macro-regions are the main instruments to overcome the weaknesses of the incentive-based approach in the EU's conditionality (or, as it is described here, its ‘carrot crisis’).     

A comparison of three shoe sole impression lifting methods at high substrate temperatures

Footwear impressions are a common form of evidence found at crime scenes, and the accurate recovery and recording of such impressions is critical for shoe sole comparison and identification. The lifting of shoe sole impressions from hot surfaces (>30°C/86°F) and in hot environments has received little attention in the literature, particularly in relation to the recovery of class and randomly acquired characteristics (RACs) required for accurate comparisons. This study addressed this knowledge gap by comparing the performance of three common impression lifters (gelatin, adhesive, and vinyl static cling film) at recovering shoe sole impressions in dust from hot flooring substrates. Dry origin dust shoe sole impressions were made on ceramic tile, galvanized metal, and laminated wood flooring using a shoe that possessed two RACs and five class characteristics present on the sole. Substrates were left in direct full sun for five hours during a summer day prior to lifting. Performance was measured by the proportion of RACs and class characteristics visible in each lifted impression. Results demonstrated that the vinyl static cling film tested performed poorly across all substrates, particularly for metal (23.8% marks recovered), including notable shrinkage of the lifted impression. In contrast, adhesive (~96% marks recovered over all substrates), and to a lesser extent gelatin (~85%), lifts were highly successful on hot substrates. These data suggest that adhesive lifts can consistently and accurately recover shoe sole impressions from hot substrates. This study contributes critical information for crime scene examiners to improve and expand evidence recovery in hot environments.     

Early consolidation and performance crisis: The Majoritarian‐consensus democracy debate in hungary

The current period of early consolidation has been a turning point in East‐Central European democratisation. It has provoked, however, a majoritarian‐consensual debate, first of all in Hungary, as is discussed in this article in a shorter theoretical and in a longer ‘empirical’ part. The introduction deals with the conceptual framework, followed by its application as a Hungarian case study in an East‐Central European context. It is argued that Hungary may be the model for the competing conceptions of democracy in political practice, since (i) an extended version of consensual democracy was established in the early 1990s but opposed by the first government; (ii) there was an attempt by the second government to complete consensual democracy but it failed; (Hi) an abrupt turn was made towards majoritarian democracy in the late 1990s by the third government. In Hungary there has been a long debate on majoritarian versus consensual democracy, involving politicians, experts and the general public. Finally, some broad conclusions can be drawn about the troubles of the young democracies.     

Pathway to terrorist behaviors: The role of childhood experiences,personality traits,and ideological motivations in a sample of Iraqi prisoners

Radicalization to terrorism is a multifaceted process with no single theory or approach to explain it. Although research has focused on understanding the process, there is still a dearth of studies that examine an empirically driven pathway to terrorism behavior. This study examines a cross-sectional sample of incarcerated men convicted of terrorism in Iraq (N = 160). A questionnaire-guided interview included adverse childhood experiences (ACEs), conduct disorder (CD), antisocial personality disorder (ASPD), religious and political ideology, views about causes of terrorism, and the severity of terrorist acts. Path analysis was employed to examine the relationships between these factors and to identify the model with the best fit. After adjusting for age, employment, and location, results indicated that ACEs positively impacted CD, ASPD, religious guidance, and terrorism attitudes. ASPD positively affected political commitment and terrorism attitudes, but inversely affected current religious commitment. Political commitment inversely influenced terrorism attitudes. Religious commitment positively influenced the prioritization of religion in life, which subsequently impacted terrorism attitudes and behavior severity. Additionally, attitudes toward terrorism directly affected the severity of terrorism behavior. All paths in the final model were statistically significant at p < 0.05. Although these findings may be limited in generalizability due to the unique sample, results support the complex and interdependent nature of childhood and adult experiences on the development of both terrorism attitudes and the severity of terrorism behavior.
