EDUCATING SAVAGES: WILL THE REAL "SAVAGE" PLEASE STAND UP? Sponsor: International and Intercultural Communication Division Chair: Richard Morris, Arizona State University "Savagery with a Smile: Lynching Photographs as the Unmasking of White Innocence." Mark McPhail, Miami University "Savage Representations in the White Academy: Liberal Ideology and the Impossibility of Nativist Longing." S.

James Willard Perkinson, University of Denver "Educating Savages: Culture Wars in the Academy with Mary E. Stuckey ; ." Richard Morris, Arizona State University The panel is a riff on Richard Morris's essay with the same title which appeared in Quarterly Journal of Speech positing a critique of the modern educational system as a violent form of "transformational mimesis" for Native Americans. The papers in this thematic seek to draw connections between modern representational practices of the deep past as well as the recent past and trace their implications for tracking a different future for the human species on the planet. Taking modernity's encounter with the indigenous or racial ; "other" as a quintessential form of intercultural encounter, the panel reverses the primitivizing gaze to expose the barbarity lodged deep within modern Western practices of both social "order" and "scientific" rationale. 40467 9: 30 to 10: 45 Convention Center 2nd Level Room 212 A.

How to use dofetilide : use dofetilide as directed by your doctor. Essarily identical, to that in vertebrates Akaike et al., 198 1; Gerschenfeld et al., 1986; Hammond et al., 1987; Miller, 1987 ; . In vertebrates, the activation of b or opioid receptor types increases potassium channel conductance and indirectly reduces calcium channel conductance, while activation of K receptors causes a direct reduction in voltage dependent calcium conductance North, 1986 ; . In both cases, the net result is a reduction in neuronal discharge frequency and the amount of transmitter released. In both rodents and Cepaea, the dihydropyridine DHP ; and non-DHP calcium channel antagonists diltiazem, verapamil, and nifedipine can reduce exogenous opiate and stress-induced opioid analgesia Kavaliers and Ossenkopp, 1987, 1989 ; . This suggests similar roles for calcium-channel-related mechanisms in the mediation of opiate-induced analgesia in mammals and mollusks. In addition, pharmacological reductions of G protein activity by pertussis toxin pretreatment have similar inhibitory effects on morphine-induced analgesia in Cepaea and rodents Yu and Kavaliers, 199 1 ; . This suggests that similar intermediary messenger systems are involved in the mediation of opiate effects in Cepaea and rodents. Moreover, data also indicate that opiates have similar inhibitory effects on dopamine and possibly other monoamine systems in rodents and mollusks Stefano, 1982 ; . These observations suggest similar modes of action and sensitivities of opioid systems in vertebrates and mollusks. Magnetic Fields and Opioid Systems.

From Late Antiquity onwards, as Ernst Kantorowich has demonstrated, the notion of dying for the patria had been interpreted within the framework of the celestial homeland of Christians, i.e. paradise. In other words those who gave up their life for the patria did not do so in defence of a political entity or a temporal lord but rather for God and the celestial body of the saints or, alternatively, the advancement of Christianity here on earth Kantorowicz 1951; 1957 ; . This changed in the thirteenth century: with the growing self-confidence of the main monarchies of Western Europe and the accompanying growth in nationalism ; it happened that the crown of martyrdom began to descend on the war victims of the secular state Kantorowicz 1957, 244 ; .14 In a sense Canones 2 represents an interesting intermediary stage in this process. True, the people of Norway are exhorted to defend the Norwegian realm, but this political entity is not in the possession of the temporal lord, King Magns Erlingsson. Rather it is the preserve of the saintly lfr Haraldsson, who resides in heaven and whose sacrifice his countrymen are in a sense being encouraged to imitate. The other striking feature relates more specifically to the promise of heavenly reward. In the wake of the First Crusade, as I have mentioned, it became commonplace to equate death in battle against the Saracens with automatic entry into paradise or even the attainment of martyrdom. At no point did the Papacy state that those who died on the battlefield would be guaranteed eternal salvation. Urban II, as far as his words at Clermont can be reconstructed, only promised commutation of penance to those who took the cross, i.e. satisfaction for the penance meted out by a confessor for sins confessed. In the twelfth century other popes followed in Urbans footsteps and issued encyclicals which promised those who participated in the Crusade that their temporal punishments for all confessed sins would be commuted Brundage 1976, 11920 ; . But, and this is the main point, there was no question of issuing carteblanche promises of eternal salvation. True, Eugenius IIIs bull Quantum praedecessores 1145 46 ; , which launched the Second Crusade, promised not only commutation of penance but also the remission of all sins confessed i.e. full indulgence ; and, by implication, everlasting life for and dok.

The pharmacokinetic profile of dofetilide in human volunteers and clinical patients is characterized by high 90% ; bioavailability unaffected by coadministration of food or antacids; linear dose proportionality over the clinical dosing range; low variability both within and between patients; and protein binding of 60% to 70% that is independent of plasma concentration. Because dofetilide is excreted mainly in the urine, primarily as unchanged drug, plasma levels are increased in patients with decreased renal function; accordingly, the dose must be adjusted for renal function. In elderly patients, renal function is often decreased. Because AF affects primarily the elderly, dose adjustment becomes even more important. Dofetilide undergoes to a small extent hepatic metabolism, and its pharmacokinetic profile is not affected by mild-to-moderate hepatic dysfunction. However, inhibitors of the CYP3A4 isoenzyme could increase systemic dofetilide exposure. Dofetilide has a terminal half-life t1 2 ; of approximately 10 hours, which permits twice-daily dosing. The relationship between plasma concentrations of dofetilide and its effect on QTc is linear. Absorption and Distribution The oral bioavailability of dofetilide is 90%, with maximal plasma concentrations occurring at about 2 to 3 hours in the fasted state. Oral bioavailability is unaffected by food or antacid. The terminal half-life of TIKOSYN is approximately 10 hours; steady-state plasma concentrations are attained within 2 to 3 days, with an accumulation index of 1.5 to 2.0. Plasma concentrations are dose proportional. The plasma protein binding of dofetilide is 60% to 70% and is independent of plasma concentration and unaffected by renal impairment. The volume of distribution is 3 L kg. Metabolism and Excretion Approximately 80% of a single dose of dofetilide is excreted in urine, of which approximately 80% is excreted as unchanged dofetilide; the remaining 20% consists of inactive or minimally active metabolites. Renal elimination involves both glomerular filtration and active tubular secretion via the cation transport system, a process that can be inhibited by cimetidine and ketoconazole ; . In vitro studies with human liver microsomes show that dofetilide can be metabolized by CYP3A4 but has a low affinity for this isoenzyme. Moreover, TIKOSYN does not inhibit either CYP3A4, CYP2C9, or CYP2D6. However, inhibitors of the CYP3A4 isoenzyme could increase systemic dofetilide exposure. Metabolites of dofetilide are formed by N-dealkylation and N-oxidation. There are no quantifiable metabolites circulating in plasma, but 5 metabolites have been identified in urine.

Because of this, many practitioners will initiate dofetilide therapy only on individuals under telemetry monitoring or if serial ecg measurements of qt and qtc can be performed. Denervated cat, the respiratory response to an increase in arterial H was greater with respiratory-induced acidosis than with metabolically induced acidosis. Similarly, in the anesthetized, peripherally denervated cat, Eldridge et al. 11 ; found that raising PCO2 increased phrenic nerve activity to a greater extent than did infusion of HCl for the same change in medullary extracellular pH. Data obtained from in vitro studies further suggest that CO2 and H exert differential effects with respect to frequency and amplitude of inspiratory motor output 13, 39, 42 ; . In the isolated neonatal rodent brain stem-spinal cord preparation, for example, alteration of superfusate pH at constant PCO2 elicits changes in both respiratory burst frequency and amplitude of phrenic nerve bursts, whereas alteration of superfusate PCO2 at constant pH produces a transient change in amplitude but not frequency of phrenic bursts 13 ; . It not clear whether these reflect differences in the effect of CO2 H at one or more receptors or differential access of CO2 and H to receptors in the brain stem. AZ- and MZ-induced tissue acidosis. The exact mechanism by which microinjection of AZ and MZ produces focal tissue acidosis is not completely understood. It has been demonstrated, however, that inhibition of carbonic anhydrase by intravenous administration of AZ in both rabbits 4 ; and cats 41 ; produces an increase in brain PCO2 and medullary extracellular fluid H concentration. This increase in brain PCO2 has been suggested to result from interference with the hydration of CO2 and impairment of transport in brain capillaries and red blood cells 4, 31, 41 ; , whereas the increase in extracellular fluid H concentration has been suggested to result from an accumulation of metabolically produced H 4, 31 ; . Thus the extracellular fluid H concentration and brain PCO2 can increase independently in response to inhibition of brain carbonic anhydrase 4 ; . Because both of these mechanisms contribute to the production of focal tissue acidosis, and PCO2 and H may independently stimulate central chemoreceptors 5, 11, 13, ; , it is unclear whether our responses were evoked by focal increases in PCO2 or changes in H concentration. In our experiments, focal tissue acidosis was produced pharmacologically by unilateral microinjection of AZ and MZ. Although both AZ and MZ are cellpermeable carbonic anhydrase inhibitors, MZ differs from AZ because of its slightly higher solubility, lower plasma protein binding, and longer activity 21, 22 ; . In our experiments, we found that both agents were effective in eliciting a similar increase in peak amplitude of integrated phrenic nerve activity and frequency of phrenic bursts; however, the time course for these responses was dependent on the agent microinjected. In general, the onset latency was slightly shorter for MZ than for AZ, although this difference was not statistically significant. Furthermore, the time to the peak increase and the time to recovery were generally shorter with AZ than with MZ. These findings appear to be consistent with the pharmacological properties of AZ vs. MZ discussed above and dovonex.
