Thesis advisor: Robert Murphy / Luxury Good Consumer Trends and Advertising Spending Outcomes on the Economy This paper will explore how consumer trends in luxury goods affect the overall economy of the United States and vice versa. In economics, a luxury good is a good for which demand increases more than proportionally as income rises. Luxury goods are said to have high income elasticity of demand. In other words, as people become wealthier, they will buy more and more of the luxury good. Luxury goods are highly sensitive to economic upturns and downturns; therefore, the state of the economy will often shape consumer spending on luxury goods. However, consumer trends often fuel the economy as well. The demand for luxury goods creates jobs in manufacturing, advertising, event planning and many other areas of specialty that can contribute to a rise in GDP. An increase in exports due to a demand for American luxury goods would have a similar effect. The goal will be to discover any patterns in the data and perhaps to formulate an economic model that will expose the relationship between consumer trends in luxury goods and their effect on the economy. / Thesis (BA) — Boston College, 2008. / Submitted to: Boston College.

Three aspects of sexual reproduction and development of a Puerto Rican strain of Schistosoma mansoni in white mice were studied. It has long been known that the male in the genus Schistosoma is essential for the somatic and reproductive development of the female, but no critical study has been reported to date on whether or not the reverse is true. / In order to determine what influence, if any, the female may have on the development of male worms, somatic growth and reproductive development of males from bi- and unisexual infections were compared. No difference was noted between males of identical ages from bi- and unisexual infections (of 20 to 120 days) with respect to length, degree of reproductive development, and meiotic events. / The sequence of meiotic events in the male S. mansoni is typical of most diploid organisms: chromosome condensation, synapsis, and balanced distribution to the gametes. The mean chiasma frequency was 23.22 $\pm$ 1.4. This strain has, on the average 11.61 cross-overs or 1161 units of map lengths. / Light and transmission electron microscopy showed that the spermatozoa of Schistosomatium douthitti and Heterobilharzia americana conform to the "standard" digenean sperm morphology (filiform, with 2 axial complexes of the 9+1 microtubule arrangement), whereas the sperm of S. mansoni are more bulbous with one axoneme. S. douthitti and H. americana sperm have two free flagella that emerge posteriorly, whereas S. mansoni sperm has a single flagellum. / Source: Dissertation Abstracts International, Volume: 49-03, Section: B, page: 0604. / Major Professor: Robert B.

Caenorhabditis elegans spermatozoa are nonflagellated, ameboid cells that contain no F-actin yet are capable of crawling over solid surfaces. In this study, the role of cell surface membrane dynamics in locomotion were studied. Monoclonal antibodies against membrane proteins were generated and used to examine (1) the detailed pattern and mechanism of surface membrane movement, (2) the pattern and mechanism of insertion of new membrane components onto the spermatozoan surface, and (3) the effects of anti-cell surface protein antibodies on cell locomotion. I found that the general pattern of front-to-back membrane flow observed on other crawling metazoan cells also occurs on the pseudopod of C. elegans spermatozoa. Replacement of labelled membrane proteins lost to rearward flow occurs by a mechanism that inserts new protein onto the tips of numerous pseudopodial projections which contact the substrate during crawling, exactly where they are needed to expand the cell forward and create new sites of substrate adhesion. Membrane protein insertion occurs in the absence of cytoplasmic vesicles by a mechanism involving the post-translational, covalent attachment of lipid to the protein. Sperm do not crawl on naked glass, however, anti-cell surface antibodies immobilized on glass promote locomotion. This effect was concluded to be specific based, in part, on the ability of soluble antibody to stop locomotion in a concentration dependent fashion. / Source: Dissertation Abstracts International, Volume: 48-12, Section: B, page: 3478. / Thesis (Ph.D.)--The Florida State University, 1987.
