Following the September 11 terrorist attacks there were increased demands in America for patriotism. This attitude of hyper-patriotism, in accordance with the Bush Administration’s appropriation of the American civil religion, precluded many discursive possibilities for dissent. Yet there were some who still utilized the available outlets of public discourse to dissent from Bush Administration policies.

Show moreFollowing the September 11 terrorist attacks there were increased demands in America for patriotism. This attitude of hyper-patriotism, in accordance with the Bush Administration’s appropriation of the American civil religion, precluded many discursive possibilities for dissent. Yet there were some who still utilized the available outlets of public discourse to dissent from Bush Administration policies. Green Day’s 2004 song, “Jesus of Suburbia,” is just such an exemplary dissent discourse. What follows is divided into four sections. First, I analyze the ideological circumstances which preceded the release of “Jesus of Suburbia.” Second, I reflect on the respective conceptual insights of Ivie’s humanizing dissent and Burke’s perspective by incongruity; ultimately, I suggest their programs be joined into an individual construct: dissent by incongruity. Third, I examine how “Jesus of Suburbia” employed dissent by incongruity to critique imperialistic policies. Finally, I argue Green Day’s use of dissent by incongruity reorients the direction of dissent discourse.

Show moreGiven that religion, specifically Christianity, plays such an important role in the creation, definition, and maturation of both Hurston ' s and Gaines’s characters, I believe it is imperative to evaluate the role that this religion plays in the lives of the black characters in two seminal texts by these two authors. Clearly religious concerns are at work throughout both texts, so too, then, is the issue of race in that the black characters, via their enslaved ancestors, inherited Christianity as they knew it from white slaveholders. Thus, the study of Christianity in the lives of black Southern characters necessarily must also address racism. This analysis, then, speaks to the role that white Christian ideology plays in the shaping of black Southern characters, in terms of both identity and religion.

Show moreOn the occasion of the Ecological Society of America's centennial, we sought to learn which ecological concepts members value in terms of their utility. This required defining “concept,” and selecting concepts from current ecology textbooks that might arguably belong to a normative set. All ESA members were invited to participate in an online survey in October 2014 in which they rated 70, randomly selected concepts (out of a total set of 131) in terms of utility. Alternative to rating, respondents could mark the concept as unfamiliar. Respondents were also able list concepts that were important to them that were not encountered in the survey. Fifteen percent (1324) of the ESA membership participated in the survey. Of these, 89% were addressed in North America, 62% were male, 77% held Ph.D. degrees, 67% were involved in academia through employment or as students, and about one-half of the total were divided between community and ecosystem ecology domains of interest. The 10 highest ranked concepts (in descending order) for utility were scales (small, local, regional, global, etc.), ecosystem, habitat, species, disturbance/perturbation, organism, population, community, competition, and species life history. The 10 lowest ranked concepts (in descending order) for utility were Lotka-Volterra predator–prey/competition models, Allee effect, nutrient spiraling, character displacement, doubling time, climax, Hardy-Weinberg equation, red queen hypothesis, chemoautotroph/chemoautotrophy, and mimicry. Respondents entered 2800 terms not encountered in the survey. After parsing for concepts missed due to the survey's random presentation process, for semantic redundancy and for terms deemed non-concepts, 119 candidate concepts emerged. Many of these deserve consideration for inclusion in a normative set and introduction in textbooks. This research provides a well-considered definition of “concept,” a basis for defining a normative set of concepts expected to be known to all ecologists, and a measure of familiarity but, more importantly, a measure of usage by contemporary ecologists who were members of ESA. These results help us to understand ourselves and our science, to better teach ecology, to guide the initiatives of the collective ecological community, and to further explore the extent and intellectual structure of the principal concepts by which ecologists pursue their work.

Show moreNew technological developments have minimized training, hardware expense, and distribution problems for the production and use of instructional videos, and any science instructor can now make instructional videos for their classes. We created short "Khan style" videos for the topic of buffers in biochemistry and assigned them as homework, followed by group problem-solving sessions in class. We tested the hypothesis that "inverting the classroom" (a popular terminology for the new format) could replace traditional live lectures, which are typically followed by assigning homework problems (traditionally, mostly solved by students working alone). Using the inverted classroom method, we found that most of our students achieved mastery in solving buffer problems on an exam, without any live lecture (the class averages were ~80%). Our survey data showed that both students and faculty reviewers considered the new format to be an effective teaching tool. To validate our results, we included six survey questions concerning rigor and fairness; positive data were obtained in this regard, with a mean of ~4, on a 5-point scale. We included three separate classes in our study with grade data from 67 students and survey data from 42 students.

Show moreWe have carried out an extensive search for gamma-ray lines in the first year of public data from the spectrometer (SPI) on the INTEGRAL mission. INTEGRAL has spent a large fraction of its observing time in the Galactic plane with particular concentration in the Galactic center (GC) region (~3 Ms in the first year). Hence the most sensitive search regions are in the Galactic plane and center. The phase space of the search spans the energy range 20-8000 keV and line widths from 0 to 1000 keV (FWHM). It includes both diffuse and pointlike emission. We have searched for variable emission on timescales down to ~1000 s. Diffuse emission has been searched for on a range of different spatial scales from ~20° (the approximate field of view of the spectrometer) up to the entire Galactic plane. Our search procedures were verified by the recovery of the known gamma-ray lines at 511 and 1809 keV at the appropriate intensities and significances. We find no evidence for any previously unknown gamma-ray lines. The upper limits range from a few × 10-5 to a few × 10-2 cm-2 s-1 depending on line width, energy, and exposure; regions of strong instrumental background lines were excluded from the search. Comparison is made between our results and various prior predictions of astrophysical lines.

Show moreEast coast of India is characterized by low to medium topography and an extensive network of major estuaries, bays, mangrove creeks, rivers and tidal inlets that permit inland flooding during tropical cyclones. A coupled wave + surge hydrodynamic modeling system (ADCIRC + SWAN) is implemented to simulate storm surge, still water level elevation and wave induced setup associated with ‘Phailin’, a very severe cyclonic storm that made landfall in the Odisha State, east coast of India, during October, 2013. The coupled model provides a realistic description on the dynamic interaction of tides, wind, waves and currents, which is critical for operational needs. The study assesses the role of wave-induced setup on the net water level elevation using time varying wave radiation stress that is dynamically updated in the coupled model run. Numerical experiments are carried out for both storm surge alone and coupled mode versions. Dependent upon complex bathymetry and coastal geometry, inclusion of wave-induced setup in coupled runs results in an additional 23–36% increase of peak surge relative to an uncoupled, surge-tide simulation. The significant wave height from coupled model also shows an excellent match with observed wave heights from a wave-rider buoy located off the Odisha coast. The comparison of surge residuals between model and observation also exhibits a good match. The study highlights the importance of having a coupled wave-hydrodynamic model for operational needs in the north Indian Ocean.

Show moreThe composite thalli produced by lichen fungi in symbiosis with algae often show structural convergences with plants. Similar overall thallus forms and branching patterns may arise in lichens with very different anatomical construction, indicating the autonomy of the morphological level of organization. Fungal and algal growth and division may be highly integrated within meristem-like morphogenetic zones in many lichens, whereas in others the symbionts may contribute in a less synchronized fashion to the construction of the thallus. Although thallus-level morphology and morphogenesis may be compared with those of plants, ontogeny of the lichen thallus differs fundamentally. Observations of lichen ontogeny illustrate the formation of the thallus by unification of autonomous, primary cellular elements in co-ordinated growth. In land plants and many algae, by contrast, the plant body is the primary structure, the cellular elements of which represent secondary subdivisions. The convergences in form are based on a common mode of nutrition in combination with cell-wall building materials that impart similar structural potential. The photosynthetic apparatus forming the basis of this mode of nutrition is not a convergent feature, however, but a homologous structure that originated in the cyanobacteria and subsequently passed laterally into diverse biological lineages by repeated endosymbioses. With consolidation of these symbioses as eukaryotic algae and plants, the organismal level of organization was repeatedly re-established with increasing degrees of complexity, and morphological convergences were expressed at these new levels. In lichens, by contrast, the symbiosis is not organismally consolidated; morphological expression instead emerges at the superorganismal level.

Show moreDespite the valuable ecosystem services provided by mangrove ecosystems they remain threatened around the globe. Urban development has been a primary cause for mangrove destruction and deterioration in south Florida USA for the last several decades. As a result, the restoration of mangrove forests has become an important topic of research. Using field sampling and remote-sensing we assessed the past and present hydrologic conditions of a mangrove creek and its connected mangrove forest and brackish marsh systems located on the coast of Naples Bay in southwest Florida. We concluded that the hydrology of these connected systems had been significantly altered from its natural state due to urban development. We propose here a mangrove creek restoration plan that would extend the existing creek channel 1.1 km inland through the adjacent mangrove forest and up to an adjacent brackish marsh. We then tested the hydrologic implications using a hydraulic model of the mangrove creek calibrated with tidal data from Naples Bay and water levels measured within the creek. The calibrated model was then used to simulate the resulting hydrology of our proposed restoration plan. Simulation results showed that the proposed creek extension would restore a twice-daily flooding regime to a majority of the adjacent mangrove forest and that there would still be minimal tidal influence on the brackish marsh area, keeping its salinity at an acceptable level. This study demonstrates the utility of combining field data and hydraulic modeling to aid in the design of mangrove restoration plans.

Show moreFour coral-dominated coastal sites within two embayments (Kealakekua Bay and Honokōhau Bay) on the lee of the island of Hawai‘i were studied to assess evidence of anthropogenic impacts in these relatively pristine locales. Nutrient-loading parameters were analyzed in relation to benthic composition data. Statistically, there were significant positive relationships between nitrate + nitrite, silicate, and ammonium with the abundance of macroalgae, coralline algae, and dead coral, and between δ15N and dead coral abundance. The north outside site of Kealakekua Bay and the south outside site of Honokōhau Bay appear to be most impacted by nutrient-loading factors in each bay, respectively. Comparisons with past nutrient data indicate that nutrient inputs have increased to the two bays, and that early impacts of these increased loadings are evident. It is predicted that at current nutrient-loading rates, the north sites of Kealakekua Bay and the south sites of Honokōhau Bay will exhibit evidence of further degradation in future years.

Show morePhotoacoustic calorimetry (PAC) allows measurement of the energetics of reactive intermediates. Here, we report the examination of the metal carbonyl η5-CpMn(CO)3 (Cp, cyclopentadiene) via time-independent PAC, in a homologous series of solvents. The measured heat releases allow one to determine simultaneously the enthalpy and volume change resulting from the photodissociation of CpMn(CO)3. While the photoacoustic signal results from both of these processes, it has often been assumed that the volume change contribution to the observed photoacoustic signal is negligible for small molecules undergoing photodissociation. The current study tests the assumption of a negligible reaction volume by using a more complete treatment. The reaction of an equimolar number of photons and CpMn(CO)3 molecules, the subsequent photodissociation of the Mn–CO bond, and the ligation of a solvent molecule in an alkane solvent yields ΔHobs = 32.7 ± 0.7 kcal/mol and ΔVchem = 11.0 ± 1.3 mL/mol, both of which are independent of the quantum yield of photodissociation. A detailed analysis of the quantum yield is included (using both previously reported measurements, and new data from this work), from which we determine Φdiss = 0.635. This quantum yield allows us to determine ΔHrxn = 51.6 kcal/mol and ΔVrxn = 17.3 mL/mol. These results demonstrate that if the contribution of the reaction volume change to the photoacoustic signal is ignored, the reaction enthalpy derived would underestimate the true value by 7%. We also estimate the BDE{Cp(CO)2Mn–CO} to be 59.4 kcal/mol.

Show moreThis case study summarizes an assessment of risk of methylmercury (MeHg) exposure to fish–eating birds foraging at Stormwater Treatment Area–2 (STA–2). This assessment was required as a special condition for a permit modification authorizing flow–through operation of STA–2 Cell 1 without it first satisfying formal mercury start–up criteria. The assessment estimates the risks posed by MeHg to the great egret (Ardea albus) and the bald eagle (Haliaeetus leucocephalus). Exposure models were based on literature–derived life history parameters combined with site–specific MeHg concentrations in water, sediment, and fish. To assess risk, daily MeHg intake by females and cumulative MeHg consumed by nestlings were compared to literature–derived effects thresholds. The results indicated the likelihood was low that MeHg exposures to birds foraging throughout STA–2 would exceed effects thresholds at the time of this assessment. Birds foraging exclusively from Cell 1 or the small discharge canal were predicted to experience greater exposures and could be at potential risk. However, this worst–case risk was comparable or lower than risk levels encountered in nearby water conservation areas or the Everglades National Park.

- Abstract / Description
-
The catalyst-free, regioselective synthesis of 4′-O-substituted pyridoxine derivatives under solventless conditions is described. The methodology relies on the highly regioselective formation of the ortho-pyridinone methide from pyridoxine and subsequent oxa-Michael addition of alcohol nucleophiles. This methodology provides good to excellent yields for primary and secondary alcohols and moderate yields for tertiary alcohols.
