Descripción de una nueva especie del género Prionychus Solier, 1835 de Marruecos y redescripción de Prionychus anthracinus (Mulsant, 1856) y Prionychus lugens (Küster, 1850) (Coleoptera, Tenebrionidae, Alleculinae)

In this work we describe a new species of Prionychus from northern Morocco, specifically in the region of Nador, near Melilla. Prionychus alfonsoblancoi sp. nov. belongs to those species in which the prosternum, ahead of procoxa, angles downards in a flat or slightly convex slope, the elytra have almost no striae, the anterior margin of pronotum has no border and they show a chestnut colouration. Within the Iberian/Maghreb area, these characters make P. alfonsoblancoi resemble only P. lugens, a species from which it can be clearly separated by the length of the antennae, the pronotal punctuation and the structure of the aedeagus. P. alfonsoblancoi is the fourth species present in Morocco and, by extension, in North Africa. Given the biometrics indices currently used to describe the species of this subfamily, it has been decided to re-describe Prionychus anthracinus and Prionychus lugens according to up-to-date standards. A dichotomous key to the species of the genus that inhabit the Iberian peninsula and northern África has also been developed.En este trabajo se describe una nueva especie de Prionychus del norte de Marruecos; en concreto de la región de Nador, en las cercanías de Melilla. Prionychus alfonsoblancoi sp. nov. pertenece al grupo de especies que presentan el prosterno, por delante de las procoxas, en declive plano o algo convexo, élitros casi sin estrías, borde anterior del pronoto no rebordeado y coloración castaña. Estos caracteres hacen que en el ámbito iberomagrebí, P. alfonsoblancoi se aproxime únicamente a Prionychus lugens, especie de la que puede separarse claramente por la longitud de las antenas, el punteado del pronoto y la estructura del edeago. P. alfonsoblancoi representa la cuarta especie presente en Marruecos y, por extensión, en el norte de África. Dados los índices biométricos que actualmente se utilizan para describir las especies de esta subfamilia, se ha optado por redescribir Prionychus anthracinus y Prionychus lugens según los criterios actuales. Además se ha elaborado una clave dicotómica de las especies del género que habitan la península ibérica y el norte de África

Descripción de una nueva especie del género Leiodes Latreille, 1797 de la península ibérica (Coleoptera, Leiodidae, Leiodinae)

In this paper a new Iberian species of Leiodes Latreille, 1797 from Cabeza la Vaca (Sierra de Tudía, Badajoz, Extremadura) is described. Leiodes tudiensis n. sp. shares with some species of the genus the low mesoventral keel, elytral surface with grooves, last antennal article clearly narrower than the penultimate and conus-shaped metatarsi. Palearctic species of Leiodes with these characters are Leiodes brandisi (Holdhaus, 1902), L. ganglbaueri (Holdhaus, 1902), L. piliferus (Reitter, 1885), L. rugosa Stephens, 1829, L. skalitzkyi (Ganglbauer, 1899) and L. taurica (Breit, 1917). However, the structure of the aedeagus only shows similarity to L. taurica, although it is clearly different. The morphology of the aedeagus, together with the color pattern and other morphological details make the new species highly characteristic.Se describe una nueva especie de Leiodes Latreille, 1797 de la península ibérica. Los especímenes de la serie tipo proceden de Cabeza la Vaca (Sierra de Tudía, Badajoz, Extremadura). Leiodes tudiensis n. sp. pertenece al grupo de especies que presentan la quilla mesoventral baja y estriolas transversas en la superficie elitral, además de tener los metatarsómeros cónicos y el último artejo antenar claramente más estrecho que el penúltimo. Estos caracteres hacen que en el ámbito paleártico se aproxime a Leiodes brandisi (Holdhaus, 1902), L. ganglbaueri (Holdhaus, 1902), L. piliferus (Reitter, 1885), L. rugosa Stephens, 1829, L. skalitzkyi (Ganglbauer, 1899) y L. taurica (Breit, 1917). Sin embargo, la peculiar estructura general del edeago muestra semejanza únicamente con L. taurica; no obstante, hay diferencias fácilmente observables, lo cual sumado a diversos detalles adicionales de su morfología, permite separar las dos especies sin dificultad

Aptitud Combinatoria de líneas endocriadas (S3) de maíces forrajeros con introgresión de Zea diploperennis litis, Ooebley y Guzmán para la producción de biomasa aérea

The evaluation of inbred lines within a program of hybrid maize requires not only the determination of lines production per-se but also that of the average behaviour of their hybrid combinations (General Combining Aptitude) and their capacity to produce higher hybrid combinations among them (Specific Combining Aptitude). The aim of this work was the analysis of the General Combining Aptitude (GCA) of eleven forage maize inbred lines derived from the original crossing between Zea mays L. x Zea diploperennis Iitis, Doebley and Guzman, and the Specific Combining Aptitude (SCA) of the progeny of a pimple and direct diallelic among them. The total aerial plant forage mass and their morphological components are evaluated in comparison with a commercial hybrid. The GCA/SCA rate was high for all the production characters evaluated, showing low dominance effect or over-dominance, maybe due to a slight difference among lines. GCA was found to be significant for the production of leaves -line 4 (LE 785) presented the highest values and was also favoured with the GCA highest values for stem and whole plant. Line 2 (LE 769) GCA was found satisfactory for corncob production. The crossing (2 x 4) showed good behaviour in the production of forage and since this is due to the genetic contribution of their progeny lines, it would be interesting to begin a recurrent selection program, starting with the first segregating generation of this crossing, trying a favourable gene recombination of the forage mass.La evaluación de líneas endocriadas en un programa de maíces híbridos requiere no sólo determinar la producción perse de las mismas, sino también el comportamiento promedio de sus combinaciones híbridas (Aptitud Combinatoria General) y la capacidad de producir combinaciones híbridas superiores al cruzarse entre sí (Aptitud Combinatoria Específica). El objetivo de este trabajo fue analizar la Aptitud Combinatoria General (ACG) de once líneas endocriadas de maíces forrajeros derivados de la cruza original entre Zea mays L. x Zea dipioperennis litis, Doebley y Guzman y la Aptitud Combinatoria Específica (ACE) de la progenie de un dialélico simple directo entre ellas. Se evaluó la biomasa aérea total de la planta y sus componentes morfológicos en comparación con un híbrido comercial. La proporción de ACG/ACE fue alta en todos los caracteres de producción evaluados indicando poco efecto de dominancia o sobredominancia, quizás producto de una escasa divergencia entre las líneas. Sólo se encontró ACG significativa para la producción de hojas. Sobresale en tal sentido la línea 4 (LE 785) que también presentó los mayores valores en la producción de tallo y planta entera. La línea 2 (LE 769) se destacó por su ACG en la producción de mazorca. La cruza (2 x 4) tuvo buen comportamiento en la producción de forraje y teniendo en cuenta que se debe a la transmisión de los genes de sus líneas progenitoras sería interesante iniciar un programa de selección recurrente a partir de la primera generación segregante de esa cruza, intentando una recombinación génica favorable en la producción de biomasa

Liberal intervention in the foreign policy thinking of Tony Blair and David Cameron

David Cameron was a critic of Tony Blair’s doctrine of the international community, which was used to justify war in Kosovo and more controversially in Iraq, suggesting caution in projecting military force abroad while in opposition. However, and in spite of making severe cuts to the defence budget, the Cameron-led Coalition government signed Britain up to a military intervention in Libya within a year of coming into office. What does this say about the place liberal interventionism occupies in contemporary British foreign policy? To answer this question, this article studies the nature of what we describe as the ‘bounded liberal’ tradition that has informed British foreign policy thinking since 1945, suggesting that it puts a distinctly UK national twist on conventional conservative thought about international affairs. Its components are: scepticism of grand schemes to remake the world; instinctive Atlanticism; security through collective endeavour; and anti-appeasement. We then compare and contrast the conditions for intervention set out by Tony Blair and David Cameron. We explain the similarities but crucially also the vital differences between the two leaders’ thinking on intervention, with particular reference to Cameron’s perception that Downing Street needed to loosen its control over foreign policy-making after Iraq. Our argument is that policy substance, policy style and party political dilemmas prompted Blair and Cameron to reconnect British foreign policy with its ethical roots, ingraining a bounded liberal posture to British foreign policy after the moral bankruptcy of the John Major years. This return to a patient, pragmatic and ethically informed foreign policy meant that military operations in Kosovo and Libya were undertaken in quite different circumstances, yet came to be justified by similar arguments from the two leaders

New Sites/Sights: Exploring the White Spaces of Organization

Contemporary organization is increasingly understood as contingent and improvisational - and immersed in complex and shadowy realities where customary assumptions about the space and time of organization no longer hold. This Special Issue invites organization studies into an ambivalent space of sites/sights in organization, the double-play of this modest conceptual proposal necessary in order to open up the complex folding of the epistemological and the ontological in organization today. In this introduction we seek to establish and position a distinctive approach to what we claim to be ‘white spaces’ in organization. We show that any adequate treatment of these white spaces compels a significant breaching of the disciplinary norms of organization studies. Our argument derives from a consideration of a range of recently emerging concepts and analyses in the study of organization, all of which are suggestive of crisis and of emerging (anti-)forms of organization. This edition of Organization Studies publishes six papers and three originally commissioned book reviews that help advance this emerging problematic in organization, and which in their various ways extend our understanding of possible organizing futures. </jats:p

Counteranion-Dependent Reaction Pathways in the Protonation of Cationic Ruthenium−Vinylidene Complexes

The tetraphenylborate salts of the cationic vinylidene complexes [Cp*Ru=C=CHR(iPr2PNHPy)]+ (R = p-C6H4CF3 (1a-BPh4), Ph (1b-BPh4), p-C6H4CH3 (1c- BPh4), p-C6H4Br (1d-BPh4), tBu (1e-BPh4), H (1f-BPh4)) have been protonated using an excess of HBF4·OEt2 in CD2Cl2, furnishing the dicationic carbyne complexes [Cp*Ru≡CCH2R(iPr2PNHPy)]2+ (R = p-C6H4CF3 (2a), Ph (2b), p-C6H4CH3 (2c), p-C6H4Br (2d), tBu (2e), H (2f)), which were characterized in solution at low temperature by NMR spectroscopy. The corresponding reaction of the chloride salts 1a-Cl, 1b-Cl, 1c-Cl, and 1d-Cl followed a different pathway, instead affording the novel alkene complexes [Cp*RuCl(κ1(N),η2(C,C)-C5H4N-NHPiPr2CH=CHR)][BF4] (3a−d). In these species, the entering proton is located at the α- carbon atom of the former vinylidene ligand, which also forms a P−C bond with the phosphorus atom of the iPr2PNHPy ligand. To shed light on the reaction mechanism, DFT calculations have been performed by considering several protonation sites. The computational results suggest metal protonation followed by insertion. The coordination of chloride to ruthenium leads to alkenyl species which can undergo a P−C coupling to yield the corresponding alkene complexes. The noncoordinating nature of [BPh4]− does not allow the stabilization of the unsaturated species coming from the insertion step, thus preventing this alternative pathway
