Going up? Women in the public sector

Abstract: Purpose – This paper aims to document women's reflections on their careers over a ten-year period to provide quantitative baseline data on which to frame follow-up in-depth interviews. The participants work in the public service in Queensland (Australia) and had been recommended for, and participated in, women in management (WIM) courses conducted in the early 1990s. Design/methodology/approach – Data were collected by means of a survey (containing closed and open items) which gathered demographic data and data related to employment history, perceptions of success and satisfaction, and the women's future career expectations. Findings – Findings revealed that the percentage of women in middle and senior management had increased over the ten-year period, although not to the extent one might have anticipated, given that the women had been targeted as high flyers by their supervisors. While not content with their classification levels (i.e. seniority), the majority of the cohort viewed their careers as being successful. Practical implications – Questions arise from this study as to why women are still “not getting to the top”. There are also policy implications for the public service concerning women's possible “reinventive contribution” and training implications associated with women only courses. Originality/value – The study is part of an Australian longitudinal study on the careers of women who attended a prestigious women-only management course in the early 1990s in Queensland. This is now becoming a study of older women.

'Worldmarks': Web guidelines for socially and culturally responsive assessment in university classrooms

In the early 21st century, we need to prepare university students to navigate local and global cultures effectively and sensitively. These future professionals must develop comprehensive intercultural communication skills and understanding. Yet university assessment in Australia is often based on a western template of knowledge, which automatically places International, Indigenous, as well as certain groups of local students at a study disadvantage. It also ensures that Australian students from dominant groups are not given the opportunity to develop these vital intercultural skills. This paper explores the issues embedded in themes 1 and 4 of this conference and provides details of an innovative website developed at Queensland University of Technology in Brisbane, Australia, which encourages academic staff to investigate the hidden assumptions that can underpin their assessment practices. The website also suggests strategies academics can use to ensure that their assessment becomes more socially and culturally responsive.

A PSICOTERAPIA BREVE OPERACIONALIZADA DE MULHERES EM SITUAÇÃO DE VIOLÊNCIA DOMÉSTICA

A presente pesquisa foi realizada com duas mulheres em situação de violência doméstica e fundamentou-se nos pressupostos teóricos, técnicos e metodológicos da intervenção psicológica intitulada PBO- Psicoterapia Breve Operacionalizada. O objetivo foi analisar o processo da PBO de mulheres em situação de violência doméstica. Para a realização do diagnóstico adaptativo operacionalizado utilizou-se como instrumento a EDAO - Escala Diagnóstica Adaptativa Operacionalizada. O método utilizado foi o estudo clínico de abordagem psicanalítica que tem como base o estudo descritivo do tipo estudo de caso. As participantes realizaram cinco entrevistas diagnósticas e foram classificadas igualmente com adaptação ineficaz severa apresentando sintomas neuróticos mais limitadores, inibições restritivas e rigidez de traços caracterológicos. Elas foram encaminhadas para um atendimento em PBO. Após o final do processo realizou-se as entrevistas de Follow up que foram novamente avaliadas por meio da EDAO. Os dados obtidos nas entrevistas de follow up mostraram que houve mudança na eficácia adaptativa. As participantes foram classificadas igualmente com Adaptação Ineficaz Moderada. Elas apresentavam alguns sintomas neuróticos, inibição moderada, alguns traços caracterológicos. Conclui-se que nos casos estudados, na análise por setores, pôde-se perceber que o setor afetivo relacional constituiu-se como uma fonte de conflitos e insatisfações gerando soluções em sua maioria pouquíssimas adequadas, obviamente, influenciando decisivamente os demais setores da adaptação. Também, observou-se o fenômeno da reprodução de modelos do passado nas relações estabelecidas no presente. Nos dois casos estudados houve uma situação de violência física e de abuso sexual, que se configurava como uma herança provinda de uma dinâmica relacional da família de origem e se perpetuava livremente em suas famílias nucleares. Por último, cabe assinalar que as pacientes participaram de forma ativa durante o processo terapêutico. A partir das interpretações teorizadas foram capazes de reconsiderarem suas atitudes frente às situações-problema vividas e puderam, durante e após o processo psicoterapêutico, adotar algumas medidas concretas para enfrentá-las de forma mais adequada. Conclui-se que o processo de psicoterapia breve operacionalizado e a utilização das interpretações teorizadas parecem ter contribuído para a mudança na qualidade da eficácia adaptativa das duas mulheres que fizeram parte deste estudo.

Online approximations for wind-field models

We study online approximations to Gaussian process models for spatially distributed systems. We apply our method to the prediction of wind fields over the ocean surface from scatterometer data. Our approach combines a sequential update of a Gaussian approximation to the posterior with a sparse representation that allows to treat problems with a large number of observations.

Spatial correlations between the vacuolation, prion protein deposition and surviving neurons in variant Creutzfeldt-Jakob Disease (vCJD)

The histological features of cases of variant Creutzfeldt-Jakob disease (vCJD) are often distributed in the brain in clusters. This study investigated the spatial associations between the clusters of the vacuoles, surviving neurons, and prion protein (PrP) deposits in various brain areas in 11 cases of vCJD. Clusters of vacuoles and surviving neurons were positively correlated in the cerebral cortex but negatively correlated in the dentate gyrus. Clusters of the florid and diffuse type of PrP deposit were not positively correlated with those of either the vacuoles or the surviving neurons although a negative correlation was observed between the florid plaques and surviving neurons in some cortical areas. Clusters of the florid and diffuse deposits were either negatively correlated or uncorrelated. These data suggest: 1) that clusters of vacuoles in the cerebral cortex are associated with the presence of surviving neuronal cell bodies, 2) that the clusters of vacuoles are not spatially related to those of the PrP deposits, and 3) different factors are involved in the pathogenesis of the florid and diffuse PrP deposits.

Can we observe collective neuronal activity from macroscopic aggregate signals?

The fundamental problem faced by noninvasive neuroimaging techniques such as EEG/MEG1 is to elucidate functionally important aspects of the microscopic neuronal network dynamics from macroscopic aggregate measurements. Due to the mixing of the activities of large neuronal populations in the observed macroscopic aggregate, recovering the underlying network that generates the signal in the absence of any additional information represents a considerable challenge. Recent MEG studies have shown that macroscopic measurements contain sufficient information to allow the differentiation between patterns of activity, which are likely to represent different stimulus-specific collective modes in the underlying network (Hadjipapas, A., Adjamian, P., Swettenham, J.B., Holliday, I.E., Barnes, G.R., 2007. Stimuli of varying spatial scale induce gamma activity with distinct temporal characteristics in human visual cortex. NeuroImage 35, 518–530). The next question arising in this context is whether aspects of collective network activity can be recovered from a macroscopic aggregate signal. We propose that this issue is most appropriately addressed if MEG/EEG signals are to be viewed as macroscopic aggregates arising from networks of coupled systems as opposed to aggregates across a mass of largely independent neural systems. We show that collective modes arising in a network of simulated coupled systems can be indeed recovered from the macroscopic aggregate. Moreover, we show that nonlinear state space methods yield a good approximation of the number of effective degrees of freedom in the network. Importantly, information about hidden variables, which do not directly contribute to the aggregate signal, can also be recovered. Finally, this theoretical framework can be applied to experimental MEG/EEG data in the future, enabling the inference of state dependent changes in the degree of local synchrony in the underlying network.

Structural characterisation of hypoxia-mimicking bioactive glasses

Nickel and cobalt are both known to stimulate the hypoxia-inducible factor-1 (HIF-1a), thus significantly improving blood vessel formation in tissue engineering applications. We have manufactured nickel and cobalt doped bioactive glasses to act as a controlled delivery mechanism of these ions. The resultant structural consequences have been investigated using the methods of isotopic and isomorphic substitution applied to neutron diffraction. The structural sites present will be intimately related to their release properties in physiological fluids such as plasma and saliva, and hence the bioactivity of the material. Detailed structural knowledge is therefore a prerequisite for optimising material design. Results show that nickel and cobalt adopt a mixed structural role within these bioactive glasses occupying both network-forming (tetrahedral) and network-modifying (5-fold) geometries. Two thirds of the Ni (or Co) occupies a five-fold geometry with the remaining third in a tetrahedral environment. A direct comparison of the primary structural correlations (e.g. Si-O, Ca-O, Na-O and O-Si-O) between the archetypal 45S5 Bioglass® and the Ni and Co glasses studied here reveal no significant differences. This indicates that the addition of Ni (or Co) will have no adverse effects on the existing structure, and thus on in vitro/in vivo dissolution rates and therefore bioactivity of these glasses.

Independent modulation of engagement and connectivity of the facial network during affect processing by CACNA1C and ANK3 risk genes for bipolar disorder

IMPORTANCE Genome-wide association studies (GWASs) indicate that single-nucleotide polymorphisms in the CACNA1C and ANK3 genes increase the risk for bipolar disorder (BD). The genes influence neuronal firing by modulating calcium and sodium channel functions, respectively. Both genes modulate ?-aminobutyric acid-transmitting interneuron function and can thus affect brain regional activation and interregional connectivity. OBJECTIVE To determine whether the genetic risk for BD associated with 2 GWAS-supported risk single-nucleotide polymorphisms at CACNA1C rs1006737 and ANK3 rs10994336 is mediated through changes in regional activation and interregional connectivity of the facial affect-processing network. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional functional magnetic resonance imaging study at a research institute of 41 euthymic patients with BD and 46 healthy participants, all of British white descent. MAIN OUTCOMES AND MEASURES Blood oxygen level-dependent signal and effective connectivity measures during the facial affect-processing task. RESULTS In healthy carriers, both genetic risk variants were independently associated with increased regional engagement throughout the facial affect-processing network and increased effective connectivity between the visual and ventral prefrontal cortical regions. In contrast, BD carriers of either genetic risk variant exhibited pronounced reduction in ventral prefrontal cortical activation and visual-prefrontal effective connectivity. CONCLUSIONS AND RELEVANCE Our data demonstrate that the effect of CACNA1C rs1006737 and ANK3 rs10994336 (or genetic variants in linkage disequilibrium) on the brain converges on the neural circuitry involved in affect processing and provides a mechanism linking BD to genome-wide genetic risk variants.

Spectrally compact optical subcarrier multiplexing with 42.6Gbit/s AM-PSK payload and 2.5 Gbit/s NRZ labels

A novel approach to optical subcarrier multiplexing with compact spectrum is demonstrated using a 42.6 Gbit/s AM-PSK payload and 2.5 Gbit/s NRZ label. In this implementation, the payload introduces a 4.8 dB penalty on the label receiver sensitivity, and the label causes <1 dB penalty on the payload receiver sensitivity.
