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.     

Making Sense of Turkey’s Reaction to the Qatar Crisis

ABSTRACT

When the Qatar crisis erupted in June 2017, Turkey quickly sided with Qatar, sending tons of food supplies and deploying troops in the Emirate. Yet, from a purely geopolitical and economic perspective, Turkey would have been expected not to take sides given its much larger trade relations with Saudi Arabia and the United Arab Emirates, and their political clout in the region and beyond. It seems that the path dependence in bilateral relations between Turkey and Qatar pre-ordained the former’s reaction. More specifically, by the time the Gulf crisis erupted, Turkey and Qatar had already developed a special relationship, which strongly affected Turkey’s pro-Qatar stance.     

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.     

Public confidence in the judiciary: the interaction between political awareness and level of democracy

Apart from the studies that focus on public attitudes toward higher courts in advanced democracies, we know little about the factors that can explain public confidence in the judiciary in a comparative setting. In this regard, the goal of this study is to explain whether, and to what extent, the country's level of democracy moderates the impact of political awareness on public confidence in the judiciary. This study uses hierarchical linear models to analyse the interaction between individual and country level factors by using the World Values Survey (2005–2009) data for 49 countries and various other data sources. Our empirical results show that in advanced democracies political awareness variables like education and political participation have a positive impact on public confidence in the judiciary, whereas in countries with weak levels of democracy higher political awareness leads to increased cynicism about the judiciary. These results suggest that a one-size-fits-all approach to explain confidence in the judiciary is not possible when we are dealing with a wide range of societies that vary in terms of many characteristics, both institutional and cultural.     

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.     

Regionalism's multiple negotiations: ASEAN in East Asia

This article explains East Asian regionalism as the product of two sets of negotiations. The first negotiation is between East Asia on the one hand and global forces and structures on the other. The second negotiation is intra-regional and includes a critical negotiation between the Association of Southeast Asian Nations (ASEAN)-Southeast Asia and East/Northeast Asia, which also provides the primary focus of this article. This article details ASEAN's extensions into East Asian regionalism as part of interdependent efforts to adapt transitioning global and regional systems. Conceiving these regional negotiations to be not just economic and utilitarian but first and foremost normative, this article details the opportunities and dilemmas represented by ‘East Asia’ for ASEAN, ASEAN-Southeast Asia and Southeast Asia as a meaningful organizing principle. Dilemmas associated with the ASEAN Plus Three process, an East Asia free-trade area and the ASEAN Charter provide illustrations of East Asia's understood challenges for Southeast Asia in addition to the ways that Southeast Asian agencies have been shaping the form and content of recent East Asian efforts and also how regional-global and intra-ASEAN negotiations continue to provide key constraints.     

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.     

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.     

Fatal intoxication because of trihexyphenidyl

Trihexyphenidyl (THP) is an anticholinergic agent with forensic toxicological interest. We present a case of a 59-year-old woman with a history of paranoid disorder, who was found dead in the house where she lived alone. The autopsy findings revealed no marked pathological changes. Toxicological analysis based on gas chromatography-mass spectrometry (GC-MS) analysis revealed THP and its major metabolite (hydroxy-THP) in blood and urine, with THP concentrations of 0.053 and 0.560 mg/L, respectively. The blood and urine ethanol concentrations were low 0.096 and 0.100 g/L, respectively. Based on these results, we determined the cause of death to be THP poisoning. It is suggested that rare case of death associated with THP overdosage should be taken in conjunction with central nervous system depressants (benzodiazepines, ethanol) and/or with other pathological disorders. Thus, our case could not be supportive for this allegation.
