The Representation of the Female Body in the Multimedia Works of Regina José Galindo

The female body is central to the performance art, poetry and blog site interventions of Guatemalan Regina José Galindo. While Galindo is best known for her performance work, this article compares the hereto overlooked, distinctive and often shocking representations of the female body across her multimedia outputs. We first consider the ways in which, in all three media, Galindo presents an ‘excessive’, carnivalised, grotesque and abject female body. Second, we analyse representations of the female body that has been subjected to violence at a private and public level. In so doing, we show how Galindo not only contests hegemonic visions of gender and (national) identity but also challenges the viewer/reader to engage with, rather than look away from, the violence to which women are subjected in patriarchal society.

AUDIT OF ANTIBIOTIC USAGE IN A MEDIUM-SIZED GENERAL-HOSPITAL OVER AN 11-YEAR PERIOD - THE IMPACT OF ANTIBIOTIC POLICIES

The objective of the present study was to evaluate trends in antibiotic expenditure over an 11-year period (1982-1992) in a 370-bed district general hospital in Northern Ireland and to examine the impact of two separate antibiotic policies on antibiotic usage. A further objective was to examine the attitudes of prescribers to the second policy. Drug utilization review was used to collect information on antibiotic expenditure and usage before and after introduction of separate antibiotic policies in 1985 (not intensively monitored) and 1989 (intensively monitored). A mail questionnaire was used to determine the attitudes of prescribers. The first policy (1985) showed no benefits with regard to the number of antibiotic entities stocked (45 before, 45 after), number of dosage units issued (9.35 increase) or expenditure (33.35 increase). The 1989 policy led to significant reductions in the number of antibiotic entities stocked (28.9%), number of antibiotics issued (11.9%) and expenditure (6.1%). Expenditure began to spiral upwards when active monitoring of the second policy was suspended. The majority of prescribers (87.2%) who responded to the questionnaire (56.5% response rate) felt that the 1989 policy made a positive contribution to antibiotic usage in the hospital.

Managing SMT Resource Usage through Speculative Instruction Window Weighting

Simultaneous multithreading processors dynamically share processor resources between multiple threads. In general, shared SMT resources may be managed explicitly, for instance, by dynamically setting queue occupation bounds for each thread as in the DCRA and Hill-Climbing policies. Alternatively, resources may be managed implicitly; that is, resource usage is controlled by placing the desired instruction mix in the resources. In this case, the main resource management tool is the instruction fetch policy which must predict the behavior of each thread (branch mispredictions, long-latency loads, etc.) as it fetches instructions.

Stigmatised Identity and Service Usage in Disadvantaged Communities: Residents’, community workers’ and service providers’ perspectives.

The impact of community stigmatisation upon service usage has been largely overlooked from a social identity perspective. Specifically, the social identity-mediated mechanisms by which stigmatisation hinders service use remain unspecified. The present study examines how service providers, community workers and residents recount their experience of the stigmatisation of local community identity and how this shapes residents’ uptake of welfare, education and community support services. Twenty individual and group interviews with 10 residents, 16 community workers and six statutory service providers in economically disadvantaged communities in Limerick, Ireland, were thematically analysed.Analysis indicates that statutory service providers endorsed negative stereotypes of disadvantaged areas as separate and anti-social. The awareness of this perceived division and the experience of ‘stigma consciousness’ was reported by residents and community workers to undermine trust, leading to under-utilisation of community and government services. We argue that stigmatisation acts as a ‘social curse’ by undermining shared identity between service users and providers and so turning a potentially cooperative intragroup relationship into a fraught intergroup one. We suggest that tackling stigma in order to foster a sense of shared identity is important in creating positive and cooperative service interactions for both service users and providers.

Dynamic Buffer Management for Multimedia Services in Beyond 3G Wireless Networks

This paper investigates a dynamic buffer man-agement scheme for QoS control of multimedia services in be-yond 3G wireless systems. The scheme is studied in the context of the state-of-the-art 3.5G system i.e. the High Speed Downlink Packet Access (HSDPA) which enhances 3G UMTS to support high-speed packet switched services. Unlike earlier systems, UMTS-evolved systems from HSDPA and beyond incorporate mechanisms such as packet scheduling and HARQ in the base station necessitating data buffering at the air interface. This introduces a potential bottleneck to end-to-end communication. Hence, buffer management at the air interface is crucial for end-to-end QoS support of multimedia services with multi-plexed parallel diverse flows such as video and data in the same end-user session. The dynamic buffer management scheme for HSDPA multimedia sessions with aggregated real-time and non real-time flows is investigated via extensive HSDPA simulations. The impact of the scheme on end-to-end traffic performance is evaluated with an example multimedia session comprising a real-time streaming flow concurrent with TCP-based non real-time flow. Results demonstrate that the scheme can guar-antee the end-to-end QoS of the real-time streaming flow, whilst simultaneously protecting the non real-time flow from starva-tion resulting in improved end-to-end throughput performance

Dynamic Buffer Management for Multimedia Services in 3.5G Wireless Networks

This paper presents and investigates a dynamic
buffer management scheme for QoS control of multimedia
services in a 3.5G wireless system i.e. the High Speed Downlink
Packet Access (HSDPA). HSDPA was introduced to enhance
UMTS for high-speed packet switched services. With HSDPA,
packet scheduling and HARQ mechanisms in the base station
require data buffering at the air interface thus introducing a
potential bottleneck to end-to-end communication. Hence, for
multimedia services with multiplexed parallel diverse flows
such as video and data in the same end-user session, buffer
management schemes in the base station are essential to support
end-to-end QoS provision. We propose a dynamic buffer management
scheme for HSDPA multimedia sessions with aggregated real-time and non real-time flows in the paper. The end-to-end performance impact of the scheme is evaluated with an example multimedia session comprising a real-time streaming
flow concurrent with TCP-based non real-time flow via extensive HSDPA simulations. Results demonstrate that the scheme can guarantee the end-to-end QoS of the real-time streaming flow, whilst simultaneously protecting non real-time flow from starvation resulting in improved end-to-end throughput performance

Buffer Management for Multimedia QoS control over HSDPA Downlink

HSDPA specifications include support for a flexible framework for QoS management. In this paper, it is shown how buffer management could be incorporated into HSDPA QoS framework for 'multimedia' traffic QoS control in the MAC-hs of the Node-B. A time-space-priority (TSP) scheme is proposed as viable buffer management scheme to this effect. Comparative simulation study with other schemes is presented, demonstrating the effectiveness of the TSP buffer management scheme for 'multimedia' service QoS control in HSDPA Node-B data buffers
