DNA was extracted from the extinct American mastodon, the extinct woolly mammoth, and the modern Asian and African elephants to test the traditional morphologically based phylogeny within Elephantidae. Phylogenetic analyses of the aligned sequences of the mitochondrial gene cytochrome b support a monophyletic Asian elephant-woolly mammoth clade when the American mastodon is used as an outgroup. Previous molecular studies were unable to resolve the relationships of the woolly mammoth, Asian elephant, and African elephant because the sequences appear to have evolved at heterogeneous rates and inappropriate outgroups were used for analysis. The results demonstrate the usefulness of fossil molecular data from appropriate sister taxa for resolving phylogenies of highly derived or early radiating lineages.

The trinucleotide/amino acid relationships of the present-day genetic code are established by the amino-acylation reactions of tRNA synthetases, whereby each of 20 specific amino acids is attached to its cognate tRNAs, which bear anticodon trinucleotides. Because of its universality, the appearance of the modern genetic code is thought to predate the separation of prokaryotic and eukaryotic organisms in the universal phylogenetic tree. In the light of new sequence information, we present here a phylogenetic analysis that shows an unusual picture for tyrosyl- and tryptophanyl-tRNA synthetases. Ij particular, the eukaryotic tyrosyl- and tryptophanyl-tRNA synthetases are more related to each other than to their respective prokaryotic counterparts. In contrast, each of the other 18 eukaryotic synthetases is more related to its prokaryotic counterpart than to any eukaryotic synthetase specific for a different amino acid. Our results raise the possibility that present day tyrosyl- and tryptophanyl-tRNA synthetases appeared after the separation of nucleated cells from eubacteria. The results have implications for the development of the genetic code.

The association of species of yucca and their pollinating moths is considered one of the two classic cases of obligate mutualism between floral hosts and their pollinators. The system involves the active collection of pollen by females of two prodoxid moth genera and the subsequent purposeful placement of the pollen on conspecific stigmas of species of Yucca. Yuccas essentially depend on the moths for pollination and the moths require Yucca ovaries for oviposition. Because of the specificity involved, it has been assumed that the association arose once, although it has been suggested that within the prodoxid moths as a whole, pollinators have arisen from seed predators more than once. We show, by using phylogenies generated from three molecular data sets, that the supposed restriction of the yucca moths and their allies to the Agavaceae is an artifact caused by an incorrect circumscription of this family. In addition we provide evidence that Yucca is not monophyletic, leading to the conclusion that the modern Yucca-yucca moth relationship developed independently more than once by colonization of a new host.

Il lavoro di ricerca presentato in questa tesi di dottorato riguarda l'applicazione di studi di modellistica molecolare per l'individuazione di nuovi approcci farmacologici nel campo della neuroprotezione e del controllo della proliferazione di cellule staminali. Durante il mio dottorato di ricerca, mi sono concentrata sullo studio del sistema degli endocannabinoidi come target per lo sviluppo di nuovi trattamenti neuroprotettivi. In particolare, la mia ricerca ha avuto come obiettivo la modulazione dei livelli di 2-arachidonilglicerolo e arachidonil-etanolamide tramite l'inibizione degli enzimi MGL (monoglyceride lipase) e FAAH (fatty acid amide hydrolase). Il mio progetto di ricerca comprende anche studi di modellistica molecolare per l'individuazione di piccole molecole in grado di inibire il complesso proteina-proteina YAP-TEAD. Tale complesso, coinvolto nei sistemi di regolazione della proliferazione cellulare, rappresenta un target di cruciale importanza nel controllo della proliferazione e differenziazione di cellule staminali e, al tempo stesso, nel controllo dell'espansione tumorale

Recently the Supreme Court has placed new limits on both the substance of the Fourth Amendment and the exclusionary that serves as the principal remedy for Fourth Amendment violations. In this Article we briefly summarize these limitations and then argue that the curtailment of the exclusionary rule has the potential to ameliorate substantive Fourth Amendment doctrine. The limited reach of the modern exclusionary rule provides the Court with license to develop an expansive new substantive framework free of the specter of a correspondingly expansive remedial framework. One point on which nearly all jurists and commentators agree is that current Fourth Amendment doctrine is a mess. We argue that the Court’s exclusionary rule cases, while frustrating and ill-conceived if viewed in isolation, provide the Court with an opportunity to revisit problematic Fourth Amendment doctrine that was born under a very different remedial regime. Such an approach would allow the Court to adhere to its current view of the exclusionary rule as a remedy of last resort while creating a Fourth Amendment with teeth. The goal is a Fourth Amendment right that is more substantial and clearly defined, but a remedy that remains limited to egregious violations of clear substantive rules. The time is now to lift the Fourth Amendment fog.

As American leadership has narrowly focused on fighting global terror in Iraq and Afghanistan, the modern version of the KGB, now known as the FSB, has been conducting continuous clandestine warfare operations against the United States. These warfare operations include strategic economic and political partnerships with anti-American entities worldwide and direct embedding of double agents in the US intelligence community. This paper investigates the role of Russia's cultural history leading to the merger of the Russian Federal Security Service (FSB) and Russian Organized Crime (ROC). This paper concludes that the FSB is the most pervasive security threat to the United States and that employing Russian native and heritage speakers of Russian in the US intelligence community compromises US national security.

The primary goal of this research is to document local perspectives by presenting a set of commentaries and meanings, in the form of narratives, related to environmental health conceptions on an Oji-Cree reserve in Northeastern Ontario, Canada. Through an ethnographic case study, this research explores how the modern-day production of a sociocentric and ecocentric self, as ethnic marker and moral category, is contributing to environmental/community health and well-being on Native reserves. Cultural representations of personhood and community based on the Medicine Wheel model, as a cognitive model, create an ontological paradigm that promotes a holistic foundation for human behaviour and interaction, as well as healthy, sustainable communities.

The question of energy security of the European Union (EU) has come high on the European political agenda since the mid-2000s as developments in the international energy sector have increasingly been perceived as a threat by the EU institutions and by the Member State governments. The externalisation of the EU’s internal energy market has in that context been presented as a means to ensure energy security. This approach, which can be called ‘post-modern’ with reference to Robert Cooper’s division of the world into different ‘ages’,1 however, shows insufficiencies in terms of energy security as a number of EU energy partners belonging to the ‘modern’ world do not accept to play the same rules. This consequently poses the questions of the relevance of the market-based approach and of the need for alternative solutions. This paper therefore argues that the market-based approach, based on the liberalisation of the European energy market, needs to be complemented by a geopolitical approach to ensure the security of the EU’s energy supplies. Such a geopolitical approach, however, still faces important challenges.

In examining the long-awaited opinion given January 22nd by the CJEU in the case concerning the European Securities and Markets Authority (ESMA), this Commentary argues that the ruling is important for the insights it yields into the modern understanding of the Meroni non-delegation doctrine. The authors, Jacques Pelkmans and Marta Simoncini, aim to extract the potential implications of the ESMA case for the place and significance of the Meroni doctrine in building up the single market. They demonstrate that the ESMA case is yet another manifestation of a slow process of “mellowing Meroni’, which is a critical condition for a new single market strategy aiming to end the remaining fragmentation of the single market – not only in financial markets but also in network industries – and to ensure its ‘proper functioning’.

President Viktor Yanukovych and his Party of Regions have been repeating the pledge to decentralise power in Ukraine and to give local government a greater decision-making role ever since the party appeared on the Ukrainian political scene. The implementation of this reform is crucial both for the economic recovery of Ukraine’s regions and the overall modernisation efforts of the Ukrainian state. At present relations between central government and the regions are regulated by Soviet-era legislation that fails to address the modern-day challenges facing Ukraine. The political elite in the country, including the opposition, appear to have reached consensus on the importance of the decentralisation reform. The first attempts to implement changes in this area were made in the late 1990s, followed by a comprehensive reform programme developed between 2007 and 2009 by Yulia Tymoshenko’s government. In 2012, the Constitutional Assembly under the President of Ukraine appointed a team of experts who drafted a document detailing the reform of local government and the territorial organisation of power1. The document envisages the implementation of what effectively are two major reforms: (1) an administrative-territorial reform, which would help consolidate the fragmented administrative structure, creating larger and more economically self-sufficient administrative units, and (2) local government reform, focusing on creating clearly defined powers for local authorities with a view to securing government funding for specific tasks delegated from central government. Nonetheless, despite these measures, and in spite of the rhetoric coming from President Yanukovych and other members of the Party of Regions, it seems unlikely that the reform will be implemented in the foreseeable future. A series of concrete political decisions taken by the president over the past three years indicate that Yanukovych has not abandoned his plan to build a highly centralised political system. This in turn limits the capacity to govern of local authorities and further restricts the sources of funding for Ukraine’s regions. This apparent resistance to change stems from the fact that by implementing the proposed reforms, the president and his political allies would be forced to relinquish much of their control over the political processes taking place in the country and would have to free up the distribution of budgetary resources between Kyiv and the regions. The implementation of the reform within the specified timeframe (i.e. by 2015) is also unlikely due to the upcoming presidential election and the deteriorating economic situation in Ukraine. Without a comprehensive reform of local government, however, Ukraine will be unable to undertake effective modernisation measures, which are key for the socio-economic development of the country’s regions.

This paper examines the association between one of the most basic institutional forms, the family, and a series of demographic, educational, social, and economic indicators across regions in Europe. Using Emmanuel Todd’s classification of medieval European family systems, we identify potential links between family types and regional disparities in household size, educational attainment, social capital, labour participation, sectoral structure, wealth, and inequality. The results indicate that medieval family structures seem to have influenced European regional disparities in virtually every indicator considered. That these links remain, despite the influence of the modern state and population migration, suggests that either such structures are extremely resilient or else they have in the past been internalised within other social and economic institutions as they developed.

The argument of this paper is that several empirical puzzles in the citizenship literature are rooted in the failure to distinguish between the mainly legal concept of nationality and the broader, political concept of citizenship. Using this distinction, the paper analysis the evolution of German and American nationality laws over the last 200 years. The historical development of both legal structures shows strong communalities. With the emergence of the modern system of nation states, the attribution of nationality to newborn children is ascribed either via the principle of descent or place of birth. With regard to the naturalization of adults, there is an increasing ethnization of law, which means that the increasing complexities of naturalization criteria are more and more structured along ethnic ideas. Although every nation building process shows some elements of ethnic self-description, it is difficult to use the legal principles of ius sanguinis and ius soli as indicators of ethnic or non-ethnic modes of community building.
