The Effect of pH on Electrolyte Detection of Fingermarks on Cartridge Cases and Subsequent Microscopic Examination

Cartridge cases may contain deposited fingermarks when the firearm was loaded ( http://www.nij.gov/pubs-sum/225320.htm , J Forensic Sci, 53 , 2008 and 812). Cartridge cases can be individualized with microscopic examination. However, heat and friction degrades the deposited fingermark on the fired cartridge cases, if any on the surface. Also, unfired and fired cartridge cases are made of metal, which is a nonporous surface that does not retain fingermarks well ( http://www.nij.gov/pubs-sum/225320.htm ). This study tests the effects of pH level on fingermark clarity on brass fired and unfired cartridge cases and microscopic striation examination (MSE). Two trials were performed to determine the optimal pH in fingermark clarity for both types of cartridges. This was performed through immersion in six pH range solutions from dilutions of sulfuric acid and sodium hydroxide for 24 h for the purpose of enhancing the fingermarks on the metal. The use of the optimal neutral pH level is suggested because immersion of the cartridge cases in pH 1–3 and 3–5 affects MSE.     

Performance Testing of a Semi-Automatic Card Punch System,Using Direct STR Profiling of DNA from Blood Samples on FTA™ Cards

The 1.2 mm Electric Coring Tool (e-Core™) was developed to increase the throughput of FTA^™ sample collection cards used during forensic workflows and is similar to a 1.2 mm Harris manual micro-punch for sampling dried blood spots. Direct short tandem repeat (STR) DNA profiling was used to compare samples taken by the e-Core tool with those taken by the manual micro-punch. The performance of the e-Core device was evaluated using a commercially available PowerPlex™ 18D STR System. In addition, an analysis was performed that investigated the potential carryover of DNA via the e-Core punch from one FTA disc to another. This contamination study was carried out using Applied Biosystems AmpflSTR™ Identifiler™ Direct PCR Amplification kits. The e-Core instrument does not contaminate FTA discs when a cleaning punch is used following excision of discs containing samples and generates STR profiles that are comparable to those generated by the manual micro-punch.     

Bystander Intervention,Bullying, and Victimization: A Multilevel Analysis of New Zealand High Schools

This study examines the association between schools and student bullying behaviors and victimization among a nationally representative sample (N = 9,107) of New Zealand high school students. In particular, the study sought to explore the role of characteristics of schools and school culture with respect to bystander behavior, while controlling for individual student factors related to victimization and bullying behaviors. Results indicated that a total of 6% of students report being bullied weekly or more often and 5% of students reported bullying other students at least weekly. Results of multilevel analyses suggested that schools characterized by students taking action to stop bullying were associated with less victimization and less reported bullying among students. In contrast, in schools where students reported teachers take action to stop bullying, there was no decline in victimization or bullying. Overall, these findings support whole-school approaches that aid students to take action to stop bullying.     

Social distance and the multimodal construction of the Other in sectarian song

This paper introduces the concept of “tonal gravity” through a multimodal analysis of a YouTube video to demonstrate how multimodality is key to the construction of “Rule Britannia” as a sectarian song. The analysis focuses upon the multimodal semiotics of social distance which has been a key concept in sociological and anthropological traditions in recent times. This concept offers a means to understand the social semiotic relationship between Self and Other in multimodal discourse. Following previous work in social semiotics and music studies which examine how visual composition, music and the voice have constructed social distance or expressions of intimacy, I introduce the concept of tonal gravity which extends the metaphors of semiotic space in previous work in the musical mode, to account for a fuller understanding of how music helps narrate the multimodal Self and Other. This is introduced via a close multimodal analysis of “Rule Britannia” as a Rangers Football fan video which is only transformed into a sectarian text through multimodal collocation where different semiotic resources in various modes act in combination to produce a dominant Self actively prejudiced against a low Other.     

Sport and Diplomacy: A Global Diplomacy Framework

ABSTRACT

The actors, or “players,” involved in the transactions of diplomacy occasioned by sport are manifold. In the case of the world’s “global game”—association football—they include but are not limited to individual footballers, football clubs, national leagues, national associations, football’s international governance structures, multi-national sponsors, and numerous hangers on. Importantly for this analysis, such a panoply of actors creates an architecture, replicated across other sports, which speak to the necessity of furthering the understanding of the relationship between sport and diplomacy. These two phenomena share a long-standing similarity in global affairs; both having been over-looked as means of comprehending relations between different polities otherwise centred on the nation-state. This exegesis advances our understanding in two areas. First, it addresses the parameters of the discussion of “sport and diplomacy” and problematises the discourse between the two with a note on language; and second, it utilises a framework provided by an appreciation of “global diplomacy” to explore concepts of communication, representation, and negotiation in sport and diplomacy.     

Traversing the Fantasy: Why Leftist Academics Must Abandon the Myth of Organic Resistance and Think Again About the Problems We Face

Violence and Mental Illness: A New Analytic Approach

Empirical studies of violence and mental illness have used many different methods. Current state-of-the-art methods gather information from both subject and collateral interviews as well as official records. Typically these sources are treated as additive. Any report of a violent incident from any source is treated as true and all reported incidents are added to generate estimates of frequency. This paper presents a new statistical technique that uses the level of agreement between the sources of data to adjust those estimates. The evidence suggests that, although the additive technique for using multiple sources correctly estimates how many people are involved, it substantially underestimates the number of incidents. The new technique substantially reduces both false negatives and false positives.     

Lessons learned from inter-laboratory studies of carbon isotope analysis of honey

Forensic application of carbon isotope ratio measurements of honey and honey protein to investigate the degree of adulteration with high fructose corn syrup or other C₄ plant sugars is well established. These measurements must use methods that exhibit suitable performance criteria, particularly with regard to measurement uncertainty and traceability – low levels of adulteration can only be detected by methods that result in suitably small measurement uncertainties such that differences of 1‰ or less can be reliably detected. Inter-laboratory exercises are invaluable to assess the state-of-the art of measurement capabilities of laboratories necessary to achieve such performance criteria. National and designated metrology institutes from a number of countries recently participated in an inter-laboratory assessment (CCQM-K140) of stable carbon isotope ratio determination of bulk honey. The same sample material was distributed to a number of forensic isotope analysis laboratories that could not participate directly in the metrological comparison. The results from these studies have demonstrated that the majority of participants provided isotope delta values with acceptable performance metrics; that all participants ensured traceability of their results; and that where measurement uncertainties were reported; these were fit-for-purpose. A number of the forensic laboratories only reported precision rather than full estimates of measurement uncertainty and this was the major cause of the few instances of questionable performance metrics. Reporting of standard deviations in place of measurement uncertainties is common practice outside metrology institutes and the implications for interpretations of small differences in isotopic compositions are discussed. The results have also highlighted a number of considerations that are useful for organisers of similar inter-laboratory studies in the future.     

Cryptocurrencies are (smart) contracts

The functioning of cryptocurrencies like Bitcoin ultimately depends on participants’ agreements to selectively disclose or conceal information. Various arguments suggest that those agreements amount to a large multilateral contract to which all participants are parties. That multilateral agreement is automatically enforced through smart contract technology. Therefore, cryptocurrency “wallet holders” are simultaneously creditors and debtors of smart contract claims vis-à-vis their cryptocurrency community.     

The Distorted Jurisprudential Discourse of Nazi Law: Uncovering the ‘Rupture Thesis’ in the Anglo-American Legal Academy

It has been remarked that the ‘rupture thesis’ prevails within the Anglo-American legal academy in its understanding of the legal system in Nazi Germany. This article explores the existence and origins of this idea—that ‘Nazi law’ represented an aberration from normal legal-historical development with a point of rupture persisting between it and the ‘normal’ or central concept of law—within jurisprudential discourse in order to illustrate the prevalence of a distorted (mis)representation of Nazi law and how this distortion is manifested within the discourse today. An analysis of the treatment of Nazi law in two major 50th anniversary publications about the 1958 Hart–Fuller debate, and a review of representations of the Third Reich within literature from the current discourse, demonstrates that the rupture thesis continues to be reproduced within jurisprudence. An examination of the role of Nazi law in the Hart–Fuller debate itself shows that it can be traced back to the debate, where it was constructed through a combination of conceptual determinism and historical omission. It concludes that the historical Nazi law has great significance for the concept of law, but neither positivism nor natural law has properly theorised the nature of the real Nazi legal system.
