Samozvanets (The Pretender)

he Russian word Samozvanets most directly translates to Imposter in English. However, for this thesis, I have selected the alternative interpretation of Pretender. Imposter implies the taking or assuming of another’s position. Pretender, more personally, carries the meaning of presenting self as something one is not. It is through the lens of the Pretender that I examine the idea of what it means to be a member of a particular ethnicity, and to engage with one’s cultural heritage. I do this through a collection of fictional stories, investigating various lives within the Russian diaspora following the dissolution of the Soviet Union. I use this lens to present some of the various ways in which Russians preserve and redefine their sense of self apart from their home country. The collection focuses its attention on themes of identity and nationalism to present the unique challenges faced by a modern diasporic community. Shadows in the Field sets the reader in a remote area of Russia and follows a young man as he attempts to pursue his dream of becoming a tailor in the immediate aftermath of the Soviet Union’s dissolution, eventually leading him to immigrate to the United States. The Distance Between Us brings the reader to a dilapidated porch outside of a house party in Boston, Massachusetts where a Russian adoptee and a runaway discuss what it means to be free from the past and present. What We Keep brings the reader further into the home, following the experience of a private tutor called to work with a traumatized Russian orphan. Moonflower expands on the idea of “the home” by inter-weaving three time periods across Moscow, Boston, and London, into the journey of a young woman iii seeking to overcome the grief of the sudden death of her mother, while attempting to establish independence from her controlling oligarch father. The Pretender concludes the collection with a Russian immigrant’s meditation on masculinity, power, and nationalism in the wake of the Russo-Ukrainian War

Synthesis of perhydrofuro[2,3-b]furans from isopentenyl alcohol through carbonyl-ene and wacker-type reactions

A range of 2-substituted perhydrofuro[2,3-b]furans have been synthesized in a stereoselective manner through a sequence involving the Lewis-acid catalyzed carbonyl-ene reaction of a protected isopentenyl alcohol with a variety of enophiles, deprotection of the corresponding monoprotected diols, and palladium-catalyzed intramolecular acetalization under Wacker-type reaction conditions.This work was generously supported by the Spanish Ministerio de Ciencia e Innovación (MICINN), grant number CTQ2007-65218 and Consolider Ingenio 2010, grant number CSD2007-00006, the Generalitat Valenciana (GV; PROMETEO/2009/039), and Fondos Europeos para el Desarrollo Regional (FEDER).

Host Shifts from Lamiales to Brassicaceae in the Sawfly Genus Athalia

Plant chemistry can be a key driver of host shifts in herbivores. Several species in the sawfly genus Athalia are important economic pests on Brassicaceae, whereas other Athalia species are specialized on Lamiales. These host plants have glucosides in common, which are sequestered by larvae. To disentangle the possible direction of host shifts in this genus, we examined the sequestration specificity and feeding deterrence of iridoid glucosides (IGs) and glucosinolates (GSs) in larvae of five species which either naturally sequester IGs from their hosts within the Plantaginaceae (Lamiales) or GSs from Brassicaceae, respectively. Furthermore, adults were tested for feeding stimulation by a neo-clerodane diterpenoid which occurs in Lamiales. Larvae of the Plantaginaceae-feeders did not sequester artificially administered p-hydroxybenzylGS and were more deterred by GSs than Brassicaceae-feeders were by IGs. In contrast, larvae of Brassicaceae-feeders were able to sequester artificially administered catalpol (IG), which points to an ancestral association with Lamiales. In line with this finding, adults of all tested species were stimulated by the neo-clerodane diterpenoid. Finally, in a phylogenetic tree inferred from genetic marker sequences of 21 Athalia species, the sister species of all remaining 20 Athalia species also turned out to be a Lamiales-feeder. Fundamental physiological pre-adaptations, such as the establishment of a glucoside transporter, and mechanisms to circumvent activation of glucosides by glucosidases are therefore necessary prerequisites for successful host shifts between Lamiales and Brassicaceae
