Reforming ‘Sydney global city’: Mapping enduring sites of institutional conflict

Local government in New South Wales (NSW) Australia presently faces the prospect radical consolidation alongside the implementation of metropolitan-wide governance structures. The pervasive modernity of these processes has been couched in the rhetoric of the need to achieve ‘Global City’ status such that Sydney can compete with other regionally-based centres. However, these narratives neglect the historically repetitive nature of these conflicts. Following from an account of the city’s early attempts at metropolitan governance, this discussion examines ‘Sydney Global City’ as it is portrayed in the advocacy literature exemplified by the work of the increasingly influential lobby group, the Committee for Sydney. We then provide an account of contemporary processes of state-local relations toward consolidation and metropolitan governance. We argue that former iterations of attempted reforms are instructive, particularly in directing attention to the institutional sites of conflict away from the economic reductionism of the ‘global cities’ narrative

Heisenberg models and Schur–Weyl duality

We present a detailed analysis of certain quantum spin systems with inhomogeneous (non-random) mean-field interactions. Examples include, but are not limited to, the interchange- and spin singlet projection interactions on complete bipartite graphs. Using two instances of the representation theoretic framework of Schur–Weyl duality, we can explicitly compute the free energy and other thermodynamic limits in the models we consider. This allows us to describe the phase transition, the ground-state phase diagram, and the expected structure of extremal states

How Do Audiologists Respond to Emotional and Psychological Concerns Raised in the Audiology Setting? Three Case Vignettes

Objectives: Emotional and psychological well-being are essential to overall health, but there is little research showing how to approach emotional and psychological concerns in the audiological setting. This study investigated audiologists’ self-reported clinical behaviors in response to emotional and psychological concerns and/or symptoms raised by audiology clients. Design: A sample of 83 Australia-based audiologists completed a survey including vignettes presenting older adults with hearing loss and experiencing symptoms consistent with either depression or grief. Content analysis was used to explore: (1) audiologists’ self-reported usual response when clients present with emotional and psychological concerns and/or symptoms in the audiological setting; (2) audiologists’ ability to identify and describe psychological symptoms; and (3) audiologists’ self-reported clinical behaviors relating to client referral for psychological support. Results: When asked to describe their usual clinical course of action in response to the vignettes, over one half the audiologists described actions that address the clients concerns related to psychological well-being. Where audiologists described how they would provide psychological support, they described modifications to the audiological rehabilitation program including involving significant others in the rehabilitation process, recommending additional support outside of the audiology setting (such as General Practitioner or psychologists), and providing emotional support and counseling. When prompted, the majority of participants recognized the two cases with depression as having a mental health condition; however, 48% of participants indicated the control case as also having a mental health condition. When asked directly, the majority of audiologists indicated that they would refer the three vignettes for specialist support; however, less than one third described referral to a General Practitioner and less than 5% described referral to a mental health professional as their normal course of action in the open response item. Twenty-five different professions/people were reported as potential sources for referral. Conclusion: These findings support the need for further training and/or resources for audiologists to enable them to appropriately detect, describe and refer for emotional and psychological concerns and/or symptoms raised by clients’ in the audiology setting

Accessibility and applicability of currently available e-mental health programs for depression for people with poststroke aphasia: Scoping review

© Stephanie Jane Clunne, Brooke Jade Ryan, Annie Jane Hill, Caitlin Brandenburg, Ian Kneebone. Background: Depression affects approximately 60% of people with aphasia 1 year post stroke and is associated with disability, lower quality of life, and mortality. Web-delivered mental health (e-mental health) programs are effective, convenient, and cost-effective for the general population and thus are increasingly used in the management of depression. However, it is unknown if such services are applicable and communicatively accessible to people with poststroke aphasia. Objective: The aim of this study was to identify freely available e-mental health programs for depression and determine their applicability and accessibility for people with poststroke aphasia. Methods: A Web-based search was conducted to identify and review freely available e-mental health programs for depression. These programs were then evaluated in terms of their (1) general features via a general evaluation tool, (2) communicative accessibility for people with aphasia via an aphasia-specific communicative accessibility evaluation tool, and (3) empirical evidence for the general population and stroke survivors with and without aphasia. The program that met the most general evaluation criteria and aphasia-specific communicative accessibility evaluation criteria was then trialed by a small subgroup of people with poststroke aphasia. Results: A total of 8 programs were identified. Of these, 4 had published evidence in support of their efficacy for use within the general population. However, no empirical evidence was identified that specifically supported any programs’ use for stroke survivors with or without aphasia. One evidence-based program scored at least 80% (16/19 and 16/20, respectively) on both the general and aphasia-specific communicative accessibility evaluation tools and was subject to a preliminary trial by 3 people with poststroke aphasia. During this trial, participants were either unable to independently use the program or gave it low usability scores on a post-trial satisfaction survey. On this basis, further evaluation was considered unwarranted. Conclusions: Despite fulfilling majority of the general evaluation and aphasia-specific evaluation criteria, the highest rated program was still found to be unsuitable for people with poststroke aphasia. Thus, e-mental health programs require substantial redevelopment if they are likely to be useful to people with poststroke aphasia

Comparing predictive abilities of longitudinal child growth models

© 2018 John Wiley & Sons, Ltd. The Bill and Melinda Gates Foundation's Healthy Birth, Growth and Development knowledge integration project aims to improve the overall health and well-being of children across the world. The project aims to integrate information from multiple child growth studies to allow health professionals and policy makers to make informed decisions about interventions in lower and middle income countries. To achieve this goal, we must first understand the conditions that impact on the growth and development of children, and this requires sensible models for characterising different growth patterns. The contribution of this paper is to provide a quantitative comparison of the predictive abilities of various statistical growth modelling techniques based on a novel leave-one-out validation approach. The majority of existing studies have used raw growth data for modelling, but we show that fitting models to standardised data provide more accurate estimation and prediction. Our work is illustrated with an example from a study into child development in a middle income country in South America

Selective expansion of viral variants following experimental transmission of a reconstituted feline immunodeficiency virus quasispecies

Following long-term infection with virus derived from the pathogenic GL8 molecular clone of feline immunodeficiency virus (FIV), a range of viral variants emerged with distinct modes of interaction with the viral receptors CD134 and CXCR4, and sensitivities to neutralizing antibodies. In order to assess whether this viral diversity would be maintained following subsequent transmission, a synthetic quasispecies was reconstituted comprising molecular clones bearing envs from six viral variants and its replicative capacity compared in vivo with a clonal preparation of the parent virus. Infection with either clonal (Group 1) or diverse (Group 2) challenge viruses, resulted in a reduction in CD4+ lymphocytes and an increase in CD8+ lymphocytes. Proviral loads were similar in both study groups, peaking by 10 weeks post-infection, a higher plateau (set-point) being achieved and maintained in study Group 1. Marked differences in the ability of individual viral variants to replicate were noted in Group 2; those most similar to GL8 achieved higher viral loads while variants such as the chimaeras bearing the B14 and B28 Envs grew less well. The defective replication of these variants was not due to suppression by the humoral immune response as virus neutralising antibodies were not elicited within the study period. Similarly, although potent cellular immune responses were detected against determinants in Env, no qualitative differences were revealed between animals infected with either the clonal or the diverse inocula. However, in vitro studies indicated that the reduced replicative capacity of variants B14 and B28 in vivo was associated with altered interactions between the viruses and the viral receptor and co-receptor. The data suggest that viral variants with GL8-like characteristics have an early, replicative advantage and should provide the focus for future vaccine development
