Lrp acts as both a positive and negative regulator for type 1 fimbriae production in Salmonella enterica serovar Typhimurium.
Leucine-responsive regulatory protein (Lrp) is known to be an indirect activator of type 1 fimbriae synthesis in Salmonella enterica serovar Typhimurium via direct regulation of FimZ, a direct positive regulator for type 1 fimbriae production. Using RT-PCR, we have shown previously that fimA transcription is dramatically impaired in both lrp-deletion (Δlrp) and constitutive-lrp expression (lrp(C)) mutant strains. In this work, we used chromosomal P(fimA)-lacZ fusions and yeast agglutination assays to confirm and extend our previous results. Direct binding of Lrp to P(fimA) was shown by an electrophoretic mobility shift assay (EMSA) and DNA footprinting assay. Site-directed mutagenesis revealed that the Lrp-binding motifs in P(fimA) play a role in both activation and repression of type 1 fimbriae production. Overproduction of Lrp also abrogates fimZ expression. EMSA data showed that Lrp and FimZ proteins independently bind to P(fimA) without competitive exclusion. In addition, both Lrp and FimZ binding to P(fimA) caused a hyper retardation (supershift) of the DNA-protein complex compared to the shift when each protein was present alone. Nutrition-dependent cellular Lrp levels closely correlated with the amount of type 1 fimbriae production. These observations suggest that Lrp plays important roles in type 1 fimbriation by acting as both a positive and negative regulator and its effect depends, at least in part, on the cellular concentration of Lrp in response to the nutritional environment

Latino politics: identity, mobilization, and representation
Due to the dramatic growth of the Latino population in America, in combination with the relative decline of the Anglo (non-Hispanic white) share, Latino Studies is increasingly at the forefront of political concern. With Latino Politics: Identity, Mobilization, and Representation, editors Rodolfo Espino, David L. Leal, and Kenneth J. Meier bring together essays from a number of leading scholars to address the ever-more important issues within the field. Providing an overview of issues surrounding Latino identity and political opinion—such as differences among Latino groups based on national origin, the importance of descriptive representation, and issues of competition and cooperation, particularly with reference to African Americans—the editors speak to the many fundamental debates ingrained in the discipline.
In addition to highlighting important contributions of the study of Latino politics to date, this volume suggests areas that have yet to be explored and, perhaps more importantly, demonstrates how the study of Latino politics relates to broader questions of American politics and society. Foregrounding debates in the overall discipline of political science, the collection will appeal to those who study Latino politics as well as those who are interested in understanding American politics and society with reference to Latino and "minority" concerns

Modification of nektonic fish distribution by piers and pile fields in an urban estuary
Large urban piers degrade habitat value for several estuarine benthic fish species by shading, but their effects on mobile nektonic species is less well understood due to sampling challenges. Dual Frequency Identification Sonar (DIDSON) allowed equal access to sampling in the water column of structured shaded and unshaded vs. open environments in both dark and light conditions by methods similar to video but without light. Sampling (n = 228, 5-minute transects) occurred under and around four large municipal piers of varying dimensions in the Hudson River estuary during day and night from summer and fall in 2007 - 2009. The distribution of small (5 - 25 cm in length) and large (25 – 850 cm) fishes were analyzed separately in recognition of functional guild differences. Small fishes occupied open water, shaded under-pier, and un-decked relict piling habitats, but were significantly more abundant during the day in open unshaded water than under adjacent piers or in piling habitats.. Small fish occurred under 3 of 4 piers of varying size and configuration at 10 - 20% of the median abundances of adjacent open water. However, while schools were rare under piers they could be very large, so that abundance greatly exceeded mean open water abundance variance so as to preclude confidence in differences among piers. The differences among habitats was not significant at night, and the difference among piers was also not significant at night. School membership for small fish appeared to mitigate adverse effects of shading and may influence scaling of their response to shading and could therefore influence pier design. Large (>25 cm) predatory fish were uncommon but responded similarly to habitat effects as did small fish. Habitats did not segregate fish by guild as small forage fish co-occurred in 65.8% of samples with large piscivores. Studies that provide species-specific and mechanistic interpretation of dynamic habitat use as well as further quantification of scaling effects could improve our understanding of how fishes respond to piers and other structures on urban shorelines.Peer reviewed

Barthes, Bakhtin, Structuralism: A Reassessment
PhDThe thesis is a comparative analysis of the shared ideas and concerns in the works of
Mikhail Bakhtin and Roland Barthes from the point of view of differences between
French and Slavic literary structuralisms. Its background argument is that the
structuralism developed in the later works of the Russian Formalists and by Prague
Structuralists and Soviet Semioticians is more historically and socially oriented than its
French version, defining the structure of a literary work as a system of all of its
elements and effects (even those that take us outside of the text, like literary tradition
and historical and political circumstances). In this sense, Bakhtin can be seen as a part
of the Slavic structuralist tradition (and not opposed to it as is often claimed), and
Barthes (seen throughout his career) is on the whole perhaps closer to the Slavic
structuralism than he is to the French.
The particular problems discussed are those of the relationship between
literature and ideology, the notions of intertextuality, heteroglossia, dialogism and
polyphony and the differences between them, and the role of the author.
Barthes and Bakhtin shared a lifelong interest in the role of ideology in literature
and the influence of authoritarian language or myth on culture in general and the literary
text in particular. They looked for ways in which the deadening effect of the
mythological (epic, monological) thought and word can be counteracted through
literature, and different versions of what Kristeva termed 'intertextuality' played an
important part in their treatment of the subject. They also both discussed the role of the
author and their voice in the literary text, and the question of their power over the text,
its characters (Bakhtin) and the reader (Barthes).
The main thread of Barthes and Bakhtin's thought focuses on the problem of
counteracting authoritarian language through literature, and the solutions they proposed
can fruitfully be seen in the light of Slavic structuralism's notions of literary structure
