How do organizations discursively negotiate organizational identity? In a longitudinal interpretive case study, we investigate the discursive practices of identity negotiations in a non-profit organization. Drawing on semi-structured interviews, documents and participant observations, and in applying a discourse analytical framework, we first identify three distinct discourses that provide the discursive resources for three different identity propositions. Then and in order to understand how these discursive resources are activated and utilized, we reconstruct four distinct discursive practices of organizational identity negotiations: (1) external comparison and differentiation (2) denial of trade-offs and harmonization (3) historization, and (4) moralization. We discuss how this structure relates to other similarly pluralistic organizational contexts.

Recent applications of Foucauldian categories in geography, spatial history and the history of town planning have opened up interesting new perspectives, with respect to both the evolution of spatial knowledge and the genealogy of territorial techniques and their relation to larger socio-political projects, that would be enriched if combined with other discursive traditions. This article proposes to conceptualise English parliamentary enclosureea favourite episode for Marxist historiography, frequently read in a strictly materialist fashioneas a precedent of a new form of sociospatial governmentality, a political technology that inaugurates a strategic manipulation of territory for social change on the threshold between feudal and capitalist spatial rationalities. I analyse the sociospatial dimensions of parliamentary enclosure’s technical and legal innovations and compare them to the forms of communal self-regulation of land use customs and everyday regionalisations that preceded it. Through a systematic, replicable mechanism of reterritorialisation, enclosure acts normalised spatial regulations, blurred regional differences in the social organisation of agriculture and erased the modes of autonomous social reproduction linked to common land. Their exercise of dispossession of material resources, social capital and community representations is interpreted therefore as an inaugural logic that would pervade the emergent spatial rationality later known as planning.

Pru p 3 has been suggested to be the primary sensitizing allergen in patients with peanut allergy in the Mediterranean area. We aimed to confirm this hypothesis, studying 79 subjects.

Adenosine has been identified in the anterior pituitary gland and is secreted from cultured folliculostellate (FS) cells. To determine whether adenosine controls the secretion of anterior pituitary hormones in vitro, adenosine was incubated with anterior pituitaries. It stimulated prolactin (PRL) release at the lowest concentration used (10−10 M); the stimulation peaked at 10−8 M with a threefold increase in release and declined to minimal stimulation at 10−4 and 10−3 M. Follicle-stimulating hormone release was maximally inhibited at 10−8 M, whereas luteinizing hormone release was not significantly inhibited. Two selective A1 adenosine receptor antagonists (10−7 or 10−5 M) had no effect on basal PRL release, but either antagonist completely blocked the response to the most effective concentration of adenosine (10−8 M). In contrast, a highly specific A2 receptor antagonist (10−7 or 10−5 M) had no effect on basal PRL release or the stimulation of PRL release induced by adenosine (10−8 M). We conclude that adenosine acts to stimulate PRL release in vitro by activating A1 receptors. Since the A1 receptors decrease intracellular-free calcium, this would decrease the activation of nitric oxide synthase in the FS cells, resulting in decreased release of nitric oxide (NO). NO inhibits PRL release by activating guanylate cyclase that synthesizes cGMP from GTP; cGMP concentrations increase in the lactotrophs leading to inhibition of PRL release. In the case of adenosine, NO release from the FS cells decreases, resulting in decreased concentrations of NO in the lactotrophs, consequent decreased cGMP formation, and resultant increased PRL release.
