A novel chitosan/tripolyphosphate/L‐lysine conjugates for latent fingerprints detection and enhancement

Most chemical and physical methods employed in visualizing latent marks have shown detrimental effects on human health and, therefore, some research groups have directed their attention to the utilization of various (bio)polymers with the aforementioned purpose. Although chitosan is widely used in medicine, pharmacy, food, and drug delivery systems, there are very few studies that address this biopolymer utilization in forensic applications, such as the detection of latent fingerprints. We used chitosan crosslinked with sodium tripolyphosphate and conjugated with L‐lysine to enhance the visualization of latent fingerprints, due to its ability to interact with fingerprint sweat residues. These conjugates were prepared using different (w/w) amounts of chitosan and tripolyphosphate (6/1; 4/1; 1/1; 1/4; and 1/6), and those with the most promising results (i.e., 6/1 formulation) were investigated in detail. Fourier transform infrared (FT‐IR) spectroscopy confirmed interactions between components of the systems. Optical microscopy and scanning electron microscope (SEM) analysis showed that prepared powder formulations were uniform in size and confirmed that chitosan/tripolyphosphate/lysine conjugates bind easily to the sweat and lipid residues present in the latent fingerprints. The testing of prepared conjugates demonstrated the potential of these systems as bio‐based powder substitution for commercially available powders.     

The Balkan Entente in Turkish–Yugoslav relations (1934–41): the Yugoslav perspective

By discussing the role of the Balkan Entente within Turkish–Yugoslav relations, this article endeavours to reflect the extent to which the Entente guaranteed security to Turkey and Yugoslavia. It deals with the 1934–41 period, which starts with the formation of the Balkan Entente and ends with the German invasion of Yugoslavia. The article is written mainly based on Yugoslav archival documents and aims to provide an alternative narrative that contests the conventional Turkish view. It also demonstrates that although the political leaders in Turkey and Yugoslavia became more optimistic about the future of the region after having signed the Balkan Entente, their perception of threat changed over time during the period of increasing instability in Europe.     

Inter‐Rater Reliability of Total Body Score—A Scale for Quantification of Corpse Decomposition

The degree of body decomposition can be quantified using Total Body Score (TBS), a scale frequently used in taphonomic or entomological studies of decomposition. Here, the inter‐rater reliability of the scale is analyzed. The study was made on 120 laymen, which were trained in the use of the scale. Participants scored decomposition of pig carcasses from photographs. It was found that the scale, when used by different people, gives homogeneous results irrespective of the user qualifications (the Krippendorff's alfa for all participants was 0.818). The study also indicated that carcasses in advanced decomposition receive significantly less accurate scores. Moreover, it was found that scores for cadavers in mosaic decomposition (i.e., representing signs of at least two stages of decomposition) are less accurate. These results demonstrate that the scale may be regarded as inter‐rater reliable. Some propositions for refinement of the scale were also discussed.     

National Parliaments and EU Fiscal Integration

This article analyses the impact of the euro crisis on national parliaments and examines their response to the deepening of EU fiscal integration and the correspondent limitation of their budgetary autonomy. It argues that the sovereign debt crisis has provoked the emergence of new channels of parliamentary involvement in EU economic governance. National parliaments have acquired various rights of approval in the European Semester, strengthened the accountability of national governments, reinforced their scrutiny over budgeting, improved their access to information, and created domestic and supranational avenues for deliberation and political contestation of European integration. In these respects, they have undergone further Europeanisation. While these reforms do not outweigh the centralisation of EU powers, they represent an embryonic step in the parliamentary adaptation to the nascent EU fiscal regime. Yet they are unlikely substantially to influence EMU policy‐making processes, because of the democratic disconnect inherent in the EU's multilevel constitution.     

Postmortem Analysis of Electrogram Records from an Implantable Cardioverter‐Defibrillator (ICD) in the Reconstruction of a Road Traffic Accident

The case of a 69‐year‐old man, equipped with an ICD and suffering from several chronic cardiac diseases, who died in a car accident, was presented. We analyzed electrogram records from the ICD explanted from the body during the autopsy, which showed that the driver had suffered from malignant ventricular arrhythmia—ventricular fibrillation (VF). A thorough analysis of the details of the accident, as well as the timing of VF and the rhythm observed after the discharge of the ICD showed that the direct cause of the accident was the episode of arrhythmia resulting in a loss of consciousness. Therefore, the presented case illustrates the usefulness of postmortem analysis of electrogram records from ICDs in the reconstruction of road traffic accidents. In such cases, if the victims are implanted with ICDs, it should be a routine procedure performed by forensic pathologists.     

Reconciling Independence and accountability at the European Central Bank: The false promise of Proceduralism

This article revisits the balancing act between independence and accountability at the European Central Bank (ECB). It contrasts procedural and substantive concepts of accountability, and challenges the mainstream idea that independence and accountability can be reconciled through narrow mandates, the indiscriminate increase of transparency, the creation of multiple channels of accountability, and the active use of judicial review. These assumptions form the pillars of a procedural type of accountability that promises to resolve the independence/accountability dilemma but fails to do so in practice. The article brings evidence to show how ECB accountability has become a complex administrative exercise that focuses on the procedural steps leading up to monetary and supervisory decisions while simultaneously limiting substantive accountability. The failure to acknowledge the trade‐off between independence and accountability (said to be ‘two sides of the same coin’) has resulted in a tendency to privilege the former over the latter.     

Products with nutrition and health claims in the Western Balkans: labelling behaviour,regulation and policy implications

This paper analyses food industry labelling behaviour in regulated and unregulated markets of products with nutrition and health claims (N&H claims) in the Western Balkans. The aim is to find out whether the intervention of the lawmakers in the form of labelling regulation improves transparency of labelling behaviour and facilitates a more informed consumer choice. The analysis is based on a shop survey of 475 products with N&H claims, conducted in six Western Balkan countries (WBC). Statistical inference is derived from the results of the Mann–Whitney and Kruskal–Wallis non-parametric tests as well as the Dunn post-test for all pairwise comparisons as a form of simultaneous nonparametric inference. Differences among the countries constituting the region are significant. In comparison with regulated markets in the region, unregulated WBC markets are characterized by a higher level of “spurious” statements dominated by regional/domestic producers not obliged to use scientifically-approved claims in their corporate practices. In these conditions, differences in labelling behaviour are expected as well, which is only partly confirmed by our testing results.     

Credit,crisis and contract enforcement: evidence from the Spanish loan market

A number of theoretical and empirical studies have shown that the development of credit markets is affected by the efficacy of enforcement institutions. A less explored question in this context is how these institutions interact with turns in the economic cycle and the impact of different types of legal procedures on credit market performance. This paper fills these gaps by analyzing how differences in the availability of credit and the evolution of non-performing loans ratios may be partially explained by regional variations in the quality of loan contract enforcement during recent periods of sustained growth (2001–2007) and recession (since 2008) in the Spanish economy. This research concludes that a rise in the clearance rate of executions (i.e., when a judge enforces the repayment of a debt) increases the ratio of total credit to GDP. However, the declaratory stage of the procedure (i.e., when a debt is firstly verified by a judge) does not seem to be statistically significant. A possible explanation to this finding is that, throughout the economic cycle, a relevant proportion of the defaults that take place are strategic (i.e., defaults by a solvent debtor). Furthermore, it is observed that, in regions where declaratory procedures are more efficient, less credit is declared as non-performing. The latter effect, however, is only observed after the onset of the “Great Recession” in 2008. This may be related to the increase of non-strategic defaults during a downturn.     

Complex suicide: an unusual case with six methods applied

Complex suicides (CSs) are committed by using more than one method. They account for 1.5-5% of all suicides. We present a case of CSs of a 44-year-old man, found dead in the vicinity of his car, in a deserted frozen field. Police investigation excluded homicide, and no medical data confirmed mental illnesses. Autopsy revealed wrist cuts, neck cuts, acid burns in the GI tract, multiple stab wounds to the head by a screwdriver, and several uncertain signs of hypothermia. Toxicology analysis (gas chromatography-mass spectrometry) confirmed ingestion of insecticide. We concluded that stab wounds to the head were the cause of death, while external hemorrhage and hypothermia were contributing factors. This is the first case of CSs reviewed in the literature where six suicide methods were applied. This particular case is interesting because the victim used a screwdriver as a tool for inflicting stab wounds to the head, which is a rare suicidal method.
