A victim of its own success: Internationalization, neoliberalism, and organizational involution at the Business Council of Australia

The focus of this article is on the Business Council of Australia (BCA), an association of the CEOs of the 100 or so largest companies operating in Australia. Since its inception the BCA has been an influential supporter of largely successful efforts to neoliberalize and internationalize the Australian economy. Running in parallel with these developments, however, the BCA has moved from being a "somewhat strong" to a relatively weak policy organization. This article argues these two trends are causally related. Neoliberal-inspired economic restructuring and economic internationalization have weakened the "logic of membership" and the "logic of influence" of the BCA, leading to a process of organizational involution. Furthermore, potential offsets to what I describe as the organizational predations of neoliberalism and internationalization - especially via a willingness or capacity to forge supportive or mutualistic relations with the state - have not been realized.

Rôle et évolution du rôle logistique des lixae dans les armées romaines

Cette recherche a pour but d’éclaircir le rôle logistique des lixae dans les armées romaines et l’évolution de celui-ci entre la fin de la période républicaine et de l’Empire tardif. Bien que ceux-ci soient souvent associés aux vivandiers et aux valets d’armée, leur présence dans les armées ne se limite pas à ces deux rôles. Aussi, il sera d’abord question du contexte civil dans les armées romaines en rapport avec les lixae. L’étymologie et l’historiographie des lixae seront ensuite traitées avant d’entreprendre la description et l’analyse de leurs différents rôles d’après les sources anciennes. La dernière partie de cette recherche sera consacrée aux différents rôles des lixae dans les armées romaines et à leur évolution à travers le temps. L’hypothèse avancée dans la recherche est celle d’une spécialisation du rôle marchand des lixae dans les armées entre la période républicaine et la période du haut empire et de l’empire tardif. Enfin, l’ensemble des sources anciennes mentionnant les lixae est regroupé dans deux catalogues en annexe de la recherche.

Dynamic changes in high and low mammographic density human breast tissues maintained in murine tissue engineering chambers during various murine peripartum states and over time

Mammographic density (MD) is a strong heritable risk factor for breast cancer, and may decrease with increasing parity. However, the biomolecular basis for MD-associated breast cancer remains unclear, and systemic hormonal effects on MD-associated risk is poorly understood. This study assessed the effect of murine peripartum states on high and low MD tissue maintained in a xenograft model of human MD. Method High and low MD human breast tissues were precisely sampled under radiographic guidance from prophylactic mastectomy specimens of women. The high and low MD tissues were maintained in separate vascularised biochambers in nulliparous or pregnant SCID mice for 4 weeks, or mice undergoing postpartum involution or lactation for three additional weeks. High and low MD biochamber material was harvested for histologic and radiographic comparisons during various murine peripartum states. High and low MD biochamber tissues in nulliparous mice were harvested at different timepoints for histologic and radiographic comparisons. Results High MD biochamber tissues had decreased stromal (p = 0.0027), increased adipose (p = 0.0003) and a trend to increased glandular tissue areas (p = 0.076) after murine postpartum involution. Stromal areas decreased (p = 0.042), while glandular (p = 0.001) and adipose areas (p = 0.009) increased in high MD biochamber tissues during lactation. A difference in radiographic density was observed in high (p = 0.0021) or low MD biochamber tissues (p = 0.004) between nulliparous, pregnant and involution groups. No differences in tissue composition were observed in high or low MD biochamber tissues maintained for different durations, although radiographic density increased over time. Conclusion High MD biochamber tissues had measurable histologic changes after postpartum involution or lactation. Alterations in radiographic density occurred in biochamber tissues between different peripartum states and over time. These findings demonstrate the dynamic nature of the human MD xenograft model, providing a platform for studying the biomolecular basis of MD-associated cancer risk. © 2013 Springer Science+Business Media New York.

Real Theta Characteristics And Automorphisms Of A Real Curve

Let X be a geometrically irreductble smooth projective cruve defined over R. of genus at least 2. that admits a nontrivial automorphism, sigma. Assume that X does not have any real points. Let tau be the antiholomorphic involution of the complexification lambda(C) of X. We show that if the action of sigma on the set S(X) of all real theta characteristics of X is trivial. then the order of sigma is even, say 2k and the automorphism tau o (sigma) over cap (lambda) of X-C has a fixed point, where (sigma) over cap is the automorphism of X x C-R defined by sigma We then show that there exists X with a real point and admitting a nontrivial automorphism sigma, such that the action of sigma on S(X) is trivial, while X/ not equal P-R(1) We also give an example of X with no real points and admitting a nontrivial automorphisim sigma such that the automorphism tau o (sigma) over cap (lambda) has a fixed point, the action of sigma on S(X) is trivial, and X/ not equal P-R(1)

A Numerical Scheme for Three-Dimensional Front Propagation and Control of Jordan Mode

As an example of a front propagation, we study the propagation of a three-dimensional nonlinear wavefront into a polytropic gas in a uniform state and at rest. The successive positions and geometry of the wavefront are obtained by solving the conservation form of equations of a weakly nonlinear ray theory. The proposed set of equations forms a weakly hyperbolic system of seven conservation laws with an additional vector constraint, each of whose components is a divergence-free condition. This constraint is an involution for the system of conservation laws, and it is termed a geometric solenoidal constraint. The analysis of a Cauchy problem for the linearized system shows that when this constraint is satisfied initially, the solution does not exhibit any Jordan mode. For the numerical simulation of the conservation laws we employ a high resolution central scheme. The second order accuracy of the scheme is achieved by using MUSCL-type reconstructions and Runge-Kutta time discretizations. A constrained transport-type technique is used to enforce the geometric solenoidal constraint. The results of several numerical experiments are presented, which confirm the efficiency and robustness of the proposed numerical method and the control of the Jordan mode.

First-passage failure and its feedback minimization of quasi-partially integrable Hamiltonian systems

An n degree-of-freedom Hamiltonian system with r (1¡r¡n) independent 0rst integrals which are in involution is calledpartially integrable Hamiltonian system. A partially integrable Hamiltonian system subject to light dampings andweak stochastic excitations is called quasi-partially integrable Hamiltonian system. In the present paper, the procedures for studying the 0rst-passage failure and its feedback minimization of quasi-partially integrable Hamiltonian systems are proposed. First, the stochastic averaging methodfor quasi-partially integrable Hamiltonian systems is brie4y reviewed. Then, basedon the averagedIt ˆo equations, a backwardKolmogorov equation governing the conditional reliability function, a set of generalized Pontryagin equations governing the conditional moments of 0rst-passage time and their boundary and initial conditions are established. After that, the dynamical programming equations and their associated boundary and 0nal time conditions for the control problems of maximization of reliability andof maximization of mean 0rst-passage time are formulated. The relationship between the backwardKolmogorov equation andthe dynamical programming equation for reliability maximization, andthat between the Pontryagin equation andthe dynamical programming equation for maximization of mean 0rst-passage time are discussed. Finally, an example is worked out to illustrate the proposed procedures and the e9ectiveness of feedback control in reducing 0rst-passage failure.

O lúdico no trabalho: o ponto de vista da atividade como operador de análise do lúdico no trabalho dos menores em um programa adolescente trabalhador

A presente tese de doutorado propõe-se a investigar o lúdico como um ingrediente das situações de trabalho. Tem-se como referência teórica os materiais oriundos da Ergologia e das abordagens clinicas sobre trabalho: Psicodinâmica do Trabalho e Clinica da Atividade. Os autores pesquisados concordam que independentemente de época histórica, cultura e classe social, jogar e brincar fazem parte da vida da criança, onde real e imaginário se confundem. O jogo constitui uma função tão fundamental para a humanidade quanto a razão e a fabricação de objetos. A cultura possui um caráter essencialmente lúdico; é no jogo e pelo jogo que a civilização surge e se desenvolve. O brincar é uma atividade humana universal, própria da saúde, fundamento de todo o viver criativo, assim como da arte e da cultura. O próprio homem medieval é muito sensível ao lúdico e convive a cada instante com o riso e com a brincadeira. O foco desta pesquisa foi uma aproximação à realidade do trabalho de alguns integrantes de um Programa Adolescente Trabalhador, com idade entre 14 e 18 anos. O campo empírico foi a Gerência Regional de Logística do Banco do Brasil, situada no bairro do Andaraí, no município do Rio de Janeiro. Sete adolescentes participaram da Comunidade Ampliada de Pesquisa. O trabalho de campo foi norteado pela preocupação em evitar a supremacia do saber científico em relação a saberes advindos da prática. Este trabalho de pesquisa não se propôs a pesquisar a realidade de trabalho dos menores, mas investigar os movimentos discursivos produzidos nos Encontros desta Comunidade de Pesquisa. Conforme a abordagem da Clínica da Atividade chama-se à atenção para vários impedimentos da emergência da dimensão lúdica em função dos constrangimentos da organização do trabalho. Por fim, questiona-se que modos de gestão olham para a realidade e o real do trabalho e da atividade, aceitando o lúdico como foco analítico, incorporando essa reserva de alternativa, investigando toda uma riqueza aí potencialmente presente e desconhecida.

Topographic changes in nascent and early mesoderm in amphioxus embryos studied by Dil labeling and by in situ hybridization for a Brachyury gene

In amphioxus embryos, the nascent and early mesoderm (including chorda-mesoderm) was visualized by expression of a Brachyury gene (AmBra-2). A band of mesoderm is first detected encircling the earliest (vegetal plate stage) gastrula sub-equatorially. Soon thereafter, the vegetal plate invaginates. resulting in a cap-shaped gastrula with the mesoderm localized at the blastoporal lip and completely encircling the blastopore. As the gastrula stage progresses, DiI (a vital dye) labeling demonstrates that the entire mesoderm is internalized by a slight involution of the epiblast into the hypoblast all around the perimeter of the blastopore. Subsequently. during the early neurula stage, the internalized mesoderm undergoes anterior extension mid-dorsally (as notochord) and dorsolaterally (in paraxial regions when segments will later form). By the late neurula stage, AmBra-2 is no longer transcribed throughout the mesoderm as a whole; instead. expression is detectable only in the posterior mesoderm and in the notochord, but not in par axial mesoderm where definitive somites have formed.

"The Black Imprint of Sandals in White Mosaic Floors": H.D.'s Mythomystical Poetics

My dissertation examines the traces of inverse (mytho)mysticism, more synchronous with mythical alchemy than transcendent mystery, in H.D.’s mature work (1946-1961). Whereas H.D.’s earliest works respond to a fin de siècle occultism and a collective psyche troubled by the eschatological distress that, as Susan Acheson writes, “was widespread amongst modernist writers grappling with …world events and with the implications of Nietzsche’s inaugural annunciation of modernity in terms of the death of God” (187), her later oeuvre is dedicated to the same work of soul undertaken by the “secret cult of Night” in Vale Ave. Here, her thematic scope faces two ways: backward to ancient Greek mystery cults and their palingenesic rites and forward to depth psychologists searching for the Soul of the World. Vale Ave plays a pronounced role in my study as symbolic guide; in its seventy-four sequences the layering of time in the “trilogy” of past, present, and future that H.D. had explored during the years of the Second World War in order to get behind the fallen walls of cause and effect collapses into two distinct phases of human origin—“meeting” (evolution) and “parting” (involution)—and the poem invites Lilith and Lucifer to be its archetypal guides. My method for the study is imaginal, entering such disciplines as history, philosophy, and theology and bringing psychological understanding to them. John Walsh’s introduction to Vale Ave notes H.D.’s theme “that the human psyche exists in a dimension outside of time and space as well as within them. In Vale Ave, H.D. presents the extremity of this dual-dimensionality: metempsychosis” (vii). However, the concept that H.D. investigates is more than a literary processus of characters who adopt different masks and appear at various junctures in a chronological unwinding of history. I explore H.D.'s works as part of a Modernist tradition of writing “books of the dead” designed not to guide the soul after death, but to draw the gaze upon “a nearer thing,” as H.D. writes in Erige Cor Tuum Ad Me In Caelum, the wisdom intrinsic in the spirit of life itself.

Unitary SK1 of unitary and graded division algebras

The reduced unitary Whitehead group $\SK$ of a graded division algebra equipped with a unitary involution (i.e., an involution of the second kind) and graded by a torsion-free abelian group is studied. It is shown that calculations in the graded setting are much simpler than their nongraded counterparts. The bridge to the non-graded case is established by proving that the unitary $\SK$ of a tame valued division algebra wih a unitary involution over a henselian field coincides with the unitary $\SK$ of its associated graded division algebra. As a consequence, the graded approach allows us not only to recover results available in the literature with substantially easier proofs, but also to calculate the unitary $\SK$ for much wider classes of division algebras over henselian fields.

Stéaryle CoA désaturase en lien avec le syndrome métabolique chez les adultes de la Polynésie française

Objectif : Évaluer l’association entre l’activité estimée du stéaryle-CoA désaturase (SCD) et le syndrome métabolique (MetS) chez une population adulte de la Polynésie française. Méthode : Étude transversale (2006-2007) de 178 adultes vivants en zone urbaine (Papeete, île de Tahiti, archipel de la Société) et rurale (Tubuai, île de Tubuai, archipel des Australes). L’activité estimée de la SCD a été calculée par le ratio produit/précurseur d’acides gras mesurés dans la membrane des érythrocytes (SCD = C16:1n-7/C16:0). Le MetS a été défini selon les critères du NIH (National Institutes of Health, États-Unis). L’analyse de covariance a été utilisée pour comparer la composition en acide gras sanguin et l’activité estimée de la SCD selon la présence de MetS et de différents critères du MetS. La régression logistique multiple a été utilisée afin d’évaluer l’association entre l’activité estimée de la SCD en quartiles et le risque de MetS. Résultats : La prévalence de surpoids était de 87 % (dont 59 % d’obèses) et celle du MetS de 32 %. Les niveaux du précurseur du C16:1n-7, l’acide palmitoléique (C16:0), entre les participants avec et sans MetS étaient similaires. Le niveau d’activité estimée de la SCD était plus élevé chez les participants avec MetS, plus particulièrement chez ceux avec une hypertriglycéridémie. Une activité estimée de la SCD plus élevée était associée positivement à un risque plus élevé de MetS (Ptendance=0,04). Conclusion : Les résultats de notre étude suggèrent qu’une augmentation de l’activité estimée de la SCD est associée positivement au risque de MetS chez la population adulte de la Polynésie française. Une étude longitudinale serait requise afin de confirmer cette association.
