“A Universal Telomerase Rna Core Structure Includes Structured Motifs Required For Binding The Telomerase Reverse Transcriptase Protein”. Proceedings Of The National Academy Of Sciences, 101, Pp. 14713–14718. doi:10.1073/pnas.0405879101.
Publisher's Version תקציר Telomerase synthesizes telomeric DNA by copying a short template sequence within its telomerase RNA component. We delineated nucleotides and base-pairings within a previously mapped central domain of the Saccharomyces cerevisiae telomerase RNA (TLC1) that are important for telomerase function and for binding to the telomerase catalytic protein Est2p. Phylogenetic comparison of telomerase RNA sequences from several budding yeasts revealed a core structure common to Saccharomyces and Kluyveromyces yeast species. We show that in this structure three conserved sequences interact to provide a binding site for Est2p positioned near the template. These results, combined with previous studies on telomerase RNAs from other budding yeasts, vertebrates, and ciliates, define a minimal universal core for telomerase RNAs.

“Veganism”. Journal Of Social Philosophy, 35, Pp. 367-379.
תקציר The article discusses the social philosophy of vegans. Vegans charge moral vegetarians with inconsistency: if eating animals is a participation in a wrong practice, consuming eggs and dairy products is likewise wrong because it is a cooperation with systematic exploitation. Vegans say that even the more humane parts of the contemporary dairy and egg industry rely on immoral practices, and that therefore moral vegetarianism is too small a step in the right direction. According to vegans, moral vegetarians have conceded that animals are not means; that human pleasure cannot override animal suffering and death; that some industries ought to be banned; and that all this carries practical implications as to their own actions. Yet they stop short of a full realization of what speciesist culture involves and what living a moral life in such an environment requires. Moral vegans distinguish themselves from moral vegetarians in accepting the practical prescriptions of altogether avoiding benefiting from animal exploitation, not just of avoiding benefiting from the killing. Vegans take the killing to be merely one aspect of the systematic exploitation of animals. The moral logic of veganism appears sound. The viability of moral vegetarianism depends on the ability to establish a meaningful difference between animal-derived products which they boycott, and those that they consume. Moral vegetarians agree that the egg and dairy industry has to be radically reformed.
Vladimir Pecherin (1807-1885), a Russian political emigré and Catholic convert was a controversial figure both in nineteenth-century Ireland and in Russian intellectual history. In his autobiographical notes and in the letters to his Russian corespondents of the 1860s and the 1870s, eventually collected in Apologia pro vita mea (Mémoires d'outre-tombe), Pecherin provides a vivid display of the evolution of Russian thought. His writings as a whole constitute an artistic presentation of the Russian Zeitgeist. Certain glaring contradictions between the ideas expressed in Pecherin's Russian correspondence and the reality of his long life within the Catholic Church require explanation. The article focuses on the authorial intention behind Pecherin’s autobiographical writing. In the hope of cementing his connection with Russia, Pecherin created in his memoirs the largely stock literary image of a “superfluous man,” a dominant literary figure of nineteenth-century Russian literature. Pecherin’s practical activity within the Catholic Church was, however, by no means superfluous, as his reputation in Dublin attests. Pecherin’s epistles to Russia invert the genre of “confession of conversion” and form a “confession of disillusionment.” Pecherin’s “hero” writes a repentant story in which he recounts a life-long pattern of devotion to various deceptive illusions, among which he counts Socialism, Hegelianism, as well as Catholicism and religion in general. The constant reinventions of himself are matched by surprising flexibility of his literary style, which seems to imitate the major voices of Russian classic literature, from Karamzin and Dostoevsky to Turgenev. If we acknowledge that Pecherin’s memoirs are primarily a work of art and only then a source of historically accurate information, many of his apparent contradictions are explained. Natalia Pervukhina, Bryn Mawr College Ph.D. 1986, is Professor at the University of Tennessee, Knoxville, is author of Anton Chekhov: The Sense and the Nonsense (Legas Publishers, 1993), V.S. Pecherin.

When viewed as a question of distributive justice the evaluation of workfare typically reflects exclusively on the distribution of income: do the physically capable have a justified claim for state support, or is it fair to demand from those who do work to subsidise this support? Rarely is workfare appraised in terms of how it affects other parties such as employers or other workers, and on the structural effects the pattern of incentives it generates brings about, or as an issue of distributive justice related to a more extensive range of objects of distribution such as access to pleasing jobs.
We propose to evaluate workfare by looking at its effects more broadly: (1) we discuss and dismiss on empirical grounds the two most common arguments in favour of workfare, namely that workfare develops self-reliance among participants and it is more economical in the use of altruism among taxpayers. (2) We suggest that workfare focuses on work as a burden and as a means to income, ignoring other beneficial aspects that are conducive to the worker’s self expression. These other benefits are distributed unevenly between two main groups: the privileged well off and the disadvantaged. (3) we argue that workfare functions as a mechanism to preserve these privileges to one class of workers at the expense of another. Or, to put it the other way, the payment of unconditional welfare to the long term unemployed might be justified as one method of mitigating unjustified privileges.
In recent years, focus on issue of the spatial has increased exponentially. Briefly charting this rise in its various theoretical forms, we may locate a common theme within many of the positions taken up in response to the spatial: a concern with turmoil and oppression, and with a shifting of both physical and political boundaries. Nowhere is this concern more explicit than in the post-colonial response to what may be seen as the most violent violation of space: the colonial appropriation of land and territory as part of the various imperial projects of previous centuries. In post-colonial writing the colonial space is acknowledged, rejected for its inauthenticity and then re-made. A detailed reading of a particular text – Ben Okri’s Infinite Riches – and of a particular space within this text – the city – allows us to exemplify some of the narrative strategies by which such a powerful reclaiming of space may be asserted by the post-colonial author. June 2004: Sara Upstone is an AHRB-funded research student at Birkbeck College, where she also teaches. She is working on transformations of space in the postcolonial, magical realist novel. She has published articles on subjects ranging from J.R.R. Tolkien to Toni Morrison. Her research interests include postcolonial, twentieth-century and contemporary literature, cultural and spatial theory and popular culture. |

“Zero-Dimensional And Quasi One-Dimensional Effects In Semiconductor Nanorods”. Nano Letters, 4, 6, Pp. 1073-1077. .
Publisher's Version תקציר 
Scanning tunneling microscopy (STM) and optical spectroscopy measurements were performed on InAs nanorods 7 to 25 nm long. Both methods reveal a clear dependence of the band-gap on length, with a red shift for longer rods. This (zero-dimension like) behavior is different than that of CdSe rods, where the band-gap is nearly insensitive to length, a signature of quasi one-dimensionality. The transition between these two regimes is governed by the ratio between the Bohr radius and the nanorod length. The gaps measured by tunneling spectroscopy are larger than the optical gaps by a factor that depends on the tunneling configuration. This is attributed to a combination of the Coulomb interaction and the voltage division between the two tunnel junctions in the STM experiment.
