This short reflection considers how humanitarian workers conceptualize and practice “the field” as a site of action. Through the use of narrative ethnography, and drawing on comparisons with the practice of academic anthropology, it attempts to draw out disciplinary assumptions that govern how and where humanitarian action is undertaken. It demonstrates how the field is a central imaginary that underpins the principles and performance of both anthropology and humanitarian action. It highlights how the conceptualization of “the field” is itself a methodological tool in the practice of humanitarian intervention.

Effects of three diphenylether herbicides [2,4-dichlorophenyl-p-nitrophenyl ether (nitrofen); 2,4,6-trichlorophenyl-4′-nitrophenyl ether (hereinafter referred to as MC-1478); and 2,4′-dinitro-4-trifluoromethyl-diphenylether (hereinafter referred to as C-6989)] were measured on phosphorylation and electron transport in spinach(Spinacia oleraceaL.) chloroplasts, and mung bean(Phaseolus aureusL., var. Jumbo) and white potato tuber(Solarium tuberosumL.) mitochondria. All of the diphenylethers acted primarily as inhibitors of chloroplast noncyclic electron transport, and the coupled photophosphorylation. The compounds ranked in the following decreasing order of inhibitory effectiveness: MC-1478 ≥ C-6989 >> nitrofen. A site of action close to light reaction II was suggested. At high molar concentrations, marginal interference with cyclic electron transport or phosphorylation was obtained. In mitochondria, MC-1478 and nitrofen acted primarily as electron transport inhibitors with malate, NADH, and succinate as substrates. MC-1478 was a slightly stronger inhibitor than nitrofen. Only slight stimulation of ADP-limited oxygen uptake was obtained during the oxidation of NADH and succinate; whereas, strong inhibition of oxygen uptake was obtained with malate. C-6989 also weakly stimulated ADP-limited oxygen uptake with NADH and succinate but differed from the two chlorinated diphenylethers in that electron transport was not inhibited when ADP was present in excess. Interference with ATP generation could be one of the mechanisms through which the phytotoxicity of diphenylether herbicides is expressed.

AbstractCharacterization and performance assessment (PA) studies for the potential high-level nuclear waste repository at Yucca Mountain require an understanding of migration mechanisms and pathways of radioactive solutes. Measurements of 36C1 in samples extracted from boreholes at the site are being used in conjunction with recent infiltration estimates to calibrate a site-scale flow and solute transport model. This exercise using the flow and solute transport model, FEHM, involves testing different model formulations and two different hypotheses to explain the occurrence of elevated 36Cl in the Calico Hills unit (CHn) which indicates younger water than in the overlying Topopah Spring unit (TSw). One hypothesis suggests fast vertical transport from the surface via fractures in the TSw to the CHn. An alternative hypothesis is that the elevated 36C1 concentrations reflect rapid horizontal flow in the CHn or at the interface between the CHn and the TSw with the source being vertical percolation under spatially isolated regions of high infiltration or at outcrops of those units. Arguments in favor of and against the hypotheses are described in conjunction with the site-scale transport studies.

In her recent book on celebrity pregnancy, legal scholar Renée Ann Cramer writes, “in the years from 1970 to 2000, popular culture became more open to performances of pregnancy; once kept secret and articulated as private, pregnancy became ‘public.’” This is not wholly true. In the English-speaking world, “celebrity pregnancy,” with its overt performances of femininity and maternity, bodily monitoring, and careful dance between the concealment and revelation of private information, had its first public moment in the long eighteenth century. That century's professional theatre was a site for the intersection of two forms of women's labor: the maternal labor of pregnancy and birth, which affected women of all classes throughout a century with rapidly rising birth rates, and the theatrical labor of professional actresses. Although the latter has been the subject of much-needed study in recent decades, the impact of maternal labor on the professional theatre of the time is only beginning to be explored. Between 1700 and 1800, birth rates for middle- and upper-class British woman rose significantly. Among the aristocracy, rates doubled from four to eight children, and middle-class women averaged seven births by the end of the century. At the same time, women in the professional theatre were inventing and modeling new forms of public womanhood, capitalizing on a burgeoning culture of female celebrity, and, in some cases, wielding exceptional economic and artistic power. Though not all actresses had children, many did, and at rates that were not unlike those of their nontheatrical counterparts. For these women, the successful balancing of maternal and theatrical labor could be vital to their careers and, in many cases, their family's survival. The need to balance personal and professional demands was all the more imperative within the hectic and extremely competitive repertory system. The day-to-day repertory of a London company was of necessity a malleable thing, accommodating short runs of popular pieces, audience requests, illnesses and absences of company members, and the perpetual state of competition between the patent houses of Covent Garden and Drury Lane. To compete profitably, managers needed competent and popular performers (bodies) and performance vehicles (texts) in which to feature them. As the available bodies changed, then, so too did the available plays for performance.

We have previously shown that the caudal nucleus tractus solitarii is a site of action of some antitussive drugs and that the caudal ventral respiratory group (cVRG) region has a crucial role in determining both the expiratory and inspiratory components of the cough motor pattern. These findings led us to suggest that the cVRG region, and possibly other neural substrates involved in cough regulation, may be sites of action of antitussive drugs. To address this issue, we investigated changes in baseline respiratory activity and cough responses to tracheobronchial mechanical stimulation following microinjections (30–50 nl) of some antitussive drugs into the cVRG of pentobarbital-anesthetized, spontaneously breathing rabbits. [d-Ala2, N-Me-Phe4,Gly5-ol]-enkephalin (DAMGO) and baclofen at the lower concentrations (0.5 mM and 0.1 mM, respectively) decreased cough number, peak abdominal activity, and peak tracheal pressure and increased cough-related total cycle duration (Tt). At the higher concentrations (5 mM and 1 mM, respectively), both drugs abolished the cough reflex. DAMGO and baclofen also affected baseline respiratory activity. Both drugs reduced peak abdominal activity, while only DAMGO increased Tt, owing to increases in expiratory time. The neurokinin-1 (NK1) receptor antagonist CP-99,994 (10 mM) decreased cough number, peak abdominal activity, and peak tracheal pressure, without affecting baseline respiration. The NK2 receptor antagonist MEN 10376 (5 mM) had no effect. The results indicate that the cVRG is a site of action of some antitussive agents and support the hypothesis that several neural substrates involved in cough regulation may share this characteristic.

The ketamine metabolite (2 R,6 R)-hydroxynorketamine has been proposed to have rapid and persistent antidepressant actions in rodents, but its mechanism of action is controversial. We have compared the ability of ( R,S)-ketamine with the (2 S,6 S)- and (2 R,6 R)-isomers of hydroxynorketamine to affect the induction of N-methyl-d-aspartate receptor–dependent long-term potentiation in the mouse hippocampus. Following pre-incubation of these compounds, we observed a concentration-dependent (1–10 μM) inhibition of long-term potentiation by ketamine and a similar effect of (2 S,6 S)-hydroxynorketamine. At a concentration of 10 μM, (2 R,6 R)-hydroxynorketamine also inhibited the induction of long-term potentiation. These findings raise the possibility that inhibition of N-methyl-d-aspartate receptor–mediated synaptic plasticity is a site of action of the hydroxynorketamine metabolites with respect to their rapid and long-lasting antidepressant-like effects.

This article focuses on acts of resistance regarding reproductive politics in contemporary Britain. Drawing on empirical research this article investigates grassroots activism around a complex moral, social, and political problem. This article therefore focuses on a site of resistance in everyday urban environments, investigating the practice and performance involved. Identifying specifically the territory(ies) and territorialities of these specific sites of resistance, this article looks at how opposing groups negotiate conflict in public space in territorial, as well as habitual, ways. Second, the article focuses on questions around the impact, distinction, and novelty both in the immediate and long term of these acts of resistance for those in public space. Here, then, the focus shifts to the reactions to this particular form of protest and questions the “acceptability” of specific resistances in the public imaginary.

I examine the staging of time, justice and performance in The Trial of Governor Eyre, investigating what this site-specific performance reveals about the experience of time in the context of colonial violence. In doing so, I show that the work’s discourse on temporality reflects a vital sense of performativity within an Afro-diasporic context. The work’s use of temporality, besides reflecting a cultural adaptation, allows for a remoulding of forms, coupling law and theatre in confronting Eyre’s mass executions of 1865. This remoulding of forms (law as theatre, theatre as law) provides a potential for postcolonial witnessing not available when either performance protocol is used on its own. Using Blazevic’s and Cale Feldman’s concept of ‘misperformance’, I argue that this play-trial arises out of a Benjaminian sense of historicity, providing an experience of inchoate justice that finds fulfilment in the present. The Trial of Governor Eyre points, more broadly, to a new ‘problem-space’ in African diaspora political theory, where resistance against colonial structures of oppression is increasingly mounted on the ground of justice itself and through which the legal apparatuses of colonialism become a site of critical memory. Through the play’s deployment of ritual and its plastic moulding of time, 1865 is enlisted as a key historical conjuncture for thinking through the cultural disenchantment of race, but also of the formalist, creative resources that can be mobilised for reimagining humanness in the contemporary moment.
