Nine Stories and the Society of the Spectacle: An Exploration into the Alienation of the Individual in the Post-War Era

This thesis analyzes the thematic links between three of J. D. Salinger’s short stories published in Nine Stories (“A Perfect Day for Bananafish,” “Down at the Dinghy,” and “Teddy”), ultimately arguing that it is a short-story cycle rooted in the quandary posed by the suicide of Seymour Glass. This conclusion is reached by assessing the influence of T. S. Eliot’s poem “The Waste Land” on these stories, something that is understood through the Marxist frame of Guy Debord’s The Society of the Spectacle

A Crack in the Ice : Attachment and Insanity in Pink Floyd\u27s The Wall

Pink Floyd’s concept album The Wall follows a musician named Pink from adolescence to adulthood as he struggles to maintain his sanity while searching for a genuine connection on the thin ice of modern life. This paper analyzes several aspects of the album to trace the character’s break with reality and what he comes to realize, such as all of the lyrics, the track-listing and the side each song appears on, and any non-musical background noise. Through the lens of Attachment Theory, a type of developmental psychology, the inevitability of Pink’s descent into madness is shown, as is how his lack of secure attachment to his mother is one of the biggest determining factors of his psycho-social and emotional advancement

Genes encoding pentatricopeptide repeat (PPR) proteins are not conserved in location in plant genomes and may be subject to diversifying selection

<p>Abstract</p> <p>Background</p> <p>The pentatricopeptide repeat (PPR) is a degenerate 35 amino acid motif that occurs in multiple tandem copies in members of a recently recognized eukaryotic gene family. Most analyzed eukaryotic genomes contain only a small number of PPR genes, but in plants the family is greatly expanded. The factors that underlie the expansion of this gene family in plants are not as yet understood.</p> <p>Results</p> <p>We show that the location of PPR genes is highly variable in comparisons between orthologous, closely related, and otherwise co-linear chromosomal regions of the <it>Brassica rapa </it>or radish and <it>Arabidopsis thaliana</it>. This observation also pertains to paralogous duplicated segments of the genomes of <it>Arabidopsis thaliana </it>and <it>Brassica rapa</it>. In addition, we show that PPR genes that seem closely linearly aligned in these comparisons are not generally found to be closely related to one another at the nucleotide and amino acid sequence level. We observe a relatively high level of non-synonomous vs synonomous changes among a group tandemly repeated radish PPR genes, suggesting that these, and possibly other PPR genes, are subject to diversifying selection. We also show that a duplicated region of the <it>Arabidopsis </it>genome possesses a relatively high density of PPR genes showing high similarity to restorers of fertility of cytoplasmic male sterile (CMS) systems of petunia, radish and rice. The PPR genes in these regions, together with the restorer genes, are more highly similar to one another, in sequence as well as in structure, than to other PPR genes, even within the same sub-family.</p> <p>Conclusion</p> <p>Our results suggest are consistent with a model in which at least some PPR genes undergo a "birth and death" process that involves transposition to unrelated chromosomal sites. PPR genes hold certain features in common with disease resistance genes (R genes), and their "nomadic" character suggests that their evolutionary expansion in plants may have involved novel molecular processes and selective pressures.</p

Introduction to NoSQL in a Traditional Database Course

Many organizations are dealing with the increasing demands of big data, so they are turning to NoSQL databases as their preferred system for handling the unique problems of capturing and storing massive amounts of data. Therefore, it is likely that employees in all sizes of organizations will encounter NoSQL databases. Thus, to be more job-ready, college students need to be introduced to this technology to begin to have a functional understanding of how it works and how to use it. This paper provides a simple project-based, teaching case that introduces NoSQL and can be easily integrated into any existing database management course to augment concepts and skills geared around traditional SQL relational databases. The teaching case was tested and student feedback (pre- and post-assessment results, shown in the data analytics and results section) indicated a significant increase in their basic knowledge of NoSQL

Location and expression of genes related to the cytoplasmic male sterility system of Brassica napus

Cytoplasrnic male sterility (CMS) is a maternally inherited defect in the production of pollen, the male gamete of the flower. This sterility can be suppressed by nuclear Restorer of Fertility (Rf) genes that normally downregulate the expression of the CMS-associated novel mitochondrial gene. In Brassica napus, nap CMS and pol CMS are associated with related chimeric mitochondrial genes orf222 and orf224, respectively. CMS in both nap and pol is associated with a polar loss of locule development, loss of synchronous locule development and clumping of sporogenous tissue away from the tapetal cell layer, as well as secondary effects on petal and bud formation. In nap CMS, early accumulation of orf222 transcripts in the locule regions of developing anthers is associated with sterility, while the absence of orf222 transcripts from the locules is associated with fertility restoration. Accumulation of novel antisense transcripts of atp6 in a cell specific manner which matches that of sense transcripts of orf222 and atp6 in nap CMS anthers may be indicative of a post-transcriptional regulatory mechanism associated with CMS in flower buds.Restoration of fertility in Brassica napus nap and pol CMS is associated with nuclearly encoded genes Rfn and Rfp, respectively. These restorers are very closely linked to one another, and may be allelic. Further efforts to isolate Rfp have narrowed the genomic region to approximately 105 kb of a syntenic region in Arabidopsis thaliana. Cosmid clones isolated from a library of Brassica rapa genomic DNA introgressed with Rfp have been successfully sorted into contigs through the application of the amplified fragment length polymorphism technique. The region to which Rfp is mapped is syntenic to a region of Arabidopsis DNA that is a duplication of a second location at the 23 megabase region of chromosome 1 of that genome. This region contains pentatricopeptide (PPR) motif-encoding genes that are highly related to other restorers of fertility of other species. By inference, Rfp from Brassica napus may encode PPR motifs. The PPR genes related to these previously characterized restorers of fertility are often found alongside the restorer genes existing as mini-clusters of several PPR-encoding genes. This is likely caused by selective pressure acting on PPR-encoding genes that resulted in diversification and multiplication of these genes. In addition, the PPR genes of this duplicated region are not syntenically located, whereas the non-PPR-encoding genes maintain their syntenic locations. The same is true for orthologous comparisons between Arabidopsis and other plant species. PPR genes are therefore malleable and capable of alteration in response to changing environmental pressures, such as the evolution of sterility inducing genes

Cosmo Alexander: His Travels and Patronage in America

Relatively little is known of European artists who worked for short periods of time in the American Colonies during the eighteenth century. Perhaps Cosmo Alexander was typical of other artists who came to America seeking greater opportunity than in their homeland, only to leave several years later, perhaps disillusioned and no wealthier. Artists who are better known stayed in America long enough to build up clientele in a broad area and produced enough works to have many survive long enough to be documented by later sources. As the subjects in many of Alexander\u27s portraits show, there was a large prosperous middle-class patronage of the art of portraiture. Considering the social conventions of the time, personal references and letters of recommendation would have facilitated travel and introduction to prospective clients. The emphasis of this research is the patronage which Cosmo Alexander found in the American Colonies as evidenced by portraits executed between 1765 and 1771. Family connections, Scottish ancestry and communities having large Scottish populations have played a part in determining probable routes. In 1961 Gavin L. M. Goodfellow submitted a thesis to Oberlin College on Cosmo Alexander. This was the first and (to date) the only extensive monograph on the artist. The thesis was general in nature, covering Alexander\u27s life and listing all paintings known at that time, only sixteen of which were believed to have been painted in America. Because he dealt in detail with Alexander\u27s total biography and stylistic characteristics, only one chapter was devoted to American works. Since Goodfellow\u27s research the number of American paintings signed by or attributed to Alexander has increased from sixteen to twenty-six. With greater documentary evidence available, patterns can be established and generalizations made which possibly are typical of other artists in similar circumstances
