The ACIGA Data Analysis programme
The Data Analysis programme of the Australian Consortium for Interferometric
Gravitational Astronomy (ACIGA) was set up in 1998 by the first author to
complement the then existing ACIGA programmes working on suspension systems,
lasers and optics, and detector configurations. The ACIGA Data Analysis
programme continues to contribute significantly in the field; we present an
overview of our activities.Comment: 10 pages, 0 figures, accepted, Classical and Quantum Gravity,

Optical and infrared spectrophotometry of 18 Markarian galaxies
Slit spectra, spectrophotometric scans and infrared broad band observations are presented. Eight of the program galaxies can be classified as Seyfert galaxies. Arguments are given that thermal, nonthermal and stellar radiation components were present. One group of Seyfert galaxies was characterized both by the presence of a high density region of gas and by a continuum dominated by nonthermal radiation. The continua of the remaining program Seyferts, which did not have a high density region of gas, were dominated by thermal radiation from dust and a stellar continuum. Ten of the galaxies, which are not Seyfert galaxies, are shown to be examples of extragalactic H 2 regions
Network sensitivity to geographical configuration
Gravitational wave astronomy will require the coordinated analysis of data
from the global network of gravitational wave observatories. Questions of how
to optimally configure the global network arise in this context. We have
elsewhere proposed a formalism which is employed here to compare different
configurations of the network, using both the coincident network analysis
method and the coherent network analysis method. We have constructed a network
model to compute a figure-of-merit based on the detection rate for a population
of standard-candle binary inspirals. We find that this measure of network
quality is very sensitive to the geographic location of component detectors
under a coincident network analysis, but comparatively insensitive under a
coherent network analysis.Comment: 7 pages, 4 figures, accepted for proceedings of the 4th Edoardo

Safeguarding Play in Virtual Worlds: Designs and Perspectives on Tween Player Participation in Community Management
Managing problematic interactions in online communities has been a challenge since the days of early text-based, multi-user environments. Research in this area has mostly focused on adults and older teens. In this article, we examine the interactions and commentaries of tween players in Whyville.net, a virtual world with (at the time of the study) more than 1.5 million registered players ages 8â16. To understand how tween players define problematic behavior and what they observe in their own community, we draw from an archive of online postings to Whyvilleâs newspaper. The postings cover the period from 2000 to 2009 and consist almost entirely of player-generated content. Complementing these tween writings are observations of an after school gaming club in which, over a period of three months, about 20 youth players ages 9â12 met almost daily to play for an hour on Whyville.net. We highlight one particular incident observed in the gaming club because it illustrates how club members dealt with problematic behavior experienced online. Finally, we address the challenges and opportunities that tween player participation in community management presents for managing online behavior and player safety

Spectral Line Removal in the LIGO Data Analysis System (LDAS)
High power in narrow frequency bands, spectral lines, are a feature of an
interferometric gravitational wave detector's output. Some lines are coherent
between interferometers, in particular, the 2 km and 4 km LIGO Hanford
instruments. This is of concern to data analysis techniques, such as the
stochastic background search, that use correlations between instruments to
detect gravitational radiation. Several techniques of `line removal' have been
proposed. Where a line is attributable to a measurable environmental
disturbance, a simple linear model may be fitted to predict, and subsequently
subtract away, that line. This technique has been implemented (as the command
oelslr) in the LIGO Data Analysis System (LDAS). We demonstrate its application
to LIGO S1 data.Comment: 11 pages, 5 figures, to be published in CQG GWDAW02 proceeding
The impact of masculinity upon men with psychosis who reside in secure forensic settings
Purpose
Masculinity is a core cognitive structure that plays a central role in organising attitudinal and behavioural processes. Yet there is limited research focussing upon the meaning of masculinity for men who have a past history of violent behaviour, who experience psychotic phenomena and reside in secure forensic settings. The paper aims to discuss these issues.
Design/methodology/approach
Q-methodology was used to elucidate the factors regarding how men who experience psychotic phenomena perceive their masculinity. Ten participants from a secure forensic setting performed a 49-statement Q-sort task.
Findings
Principal component factor analysis with varimax rotation was performed on the ten completed Q-sorts which revealed a three-factor solution, accounting for 57 per cent of the variance in the data. The factors were interpreted and discussed under the following headings: âassured and asserting maverickâ, âcalm, confident, composed conformistâ and ânurturing provider in the face of adversityâ. This revealed that men with psychosis have different, predominantly pro-social explanatory frameworks for their representation of masculinity.
Research limitations/implications
This study revealed that men with psychosis have different, predominantly pro-social explanatory frameworks for their representation of masculinity. However, the study was limited by its lack of longitudinal assessment and the inclusion of a greater number of participants may have enhanced the representativeness and generalisability of the findings.
Practical implications
Therapeutic discussions in respect of masculinity itself could provide men with the opportunity to develop newer, more adaptive conceptualisations of themselves, help them develop greater self-awareness and understanding of the sources of their presenting concerns, which in turn could enhance a provisional formulation of their difficulties. It would also be potentially valuable to understand how these patterns of masculinity map onto coping, recovery style and service engagement. Furthermore, services could also benefit from becoming more aware of hospitalisation being a shameful perhaps stigmatizing time for men with psychosis.
Social implications
It may be useful for people working in healthcare settings to be aware of how the service users they support perceive their masculinity, so the existential and deeper needs of male patients are provided with enough consideration. This is an important point, as some individuals are often reluctant or neglect to enquire about individualâs psychotic experiences and gender identification.
Originality/value
Although forensic psychiatric care is primarily populated by men who have committed violent acts, there is a limited research focussing upon the meaning of masculinity in this context. This is in spite of evidence which shows that maladaptive perceptions of masculinity can be reinforced during time spent residing in secure settings. The cultural constructs of masculinity and their respective impact upon the diagnosis, management and outcome of psychosis has also received little attention. Therefore, this research represents new and significant contributions to the field
Variations in older people\u27s emergency care use by social care setting: a systematic review of international evidence
\ua9 The Author(s) 2023. Published by Oxford University Press. BACKGROUND: Older adults\u27 use of social care and their healthcare utilization are closely related. Residents of care homes access emergency care more often than the wider older population; however, less is known about emergency care use across other social care settings. SOURCES OF DATA: A systematic review was conducted, searching six electronic databases between January 2012 and February 2022. AREAS OF AGREEMENT: Older people access emergency care from a variety of community settings. AREAS OF CONTROVERSY: Differences in study design contributed to high variation observed between studies. GROWING POINTS: Although data were limited, findings suggest that emergency hospital attendance is lowest from nursing homes and highest from assisted living facilities, whilst emergency admissions varied little by social care setting. AREAS TIMELY FOR DEVELOPING RESEARCH: There is a paucity of published research on emergency hospital use from social care settings, particularly home care and assisted living facilities. More attention is needed on this area, with standardized definitions to enable comparisons between studies
