Las estelas fronterizas y falsa-puerta como delimitadoras del espacio físico y simbólico en Egipto

El concepto de "frontera" resulta problemático debido al uso corriente que se le da al término. Está naturalizada la noción de una frontera exclusiva: una barrera que divide un territorio A de un territorio no-A, rigiendo el principio aristotélico del tercero excluido. Para el estudio de sociedades de la antigüedad debemos necesariamente desembarazarnos de tales preconceptos. En el presente trabajo nos proponemos observar la factibilidad de utilizar tal concepto para entender las divisiones (no sólo físicas) en el Antiguo Egipto. Teniendo en cuenta el uso reiterado de estelas en la demarcación del espacio proponemos, a partir del estudio de las mismas, interrogarnos acerca de qué es exactamente lo que ellas delimitan y por qué se las utiliza para ello. Los casos testigo de las estelas que marcan el límite de la ciudad de Akhetatón y las llamadas falsa-puerta nos servirán para ilustrar nuestras tesis. Las primeras, erigidas para ser vistas, decretan un límite físico; las segundas, ocultas dentro de tumbas privadas, hacen las veces de límite entre el mundo de los vivos y el de los muertos. En apariencia diferentes, encierran en realidad una misma función: separar regiones cósmicas, manteniendo al Caos fuera del territorio donde reina el Orden.

‘Capitalism’ as False Consciousness

The assertion on which this paper is based is that Capitalism has been superseded by Corporatism. I put forward an argument as to why Marxist scholars can and should abandon the idea that Capitalism still exists based on Marx’s approach to understanding political economy. Further, I argue that Marx’s method can be deployed to better understand and change the corporatist system in which we are currently living first by understanding what it means to be “labour” in a system governed by complex structures of debt.

Next Door

A one-man performance for young audiences developed with the support of the Australia Council in 2004. Next Door portrays the same half-hour in the lives of two cowboy neighbours, experienced from both sides of the wall that divides them. It’s a humorous examination of how humanity’s greatest strength – imagination, can be used to distort perception and alienate the ‘other’.

Detection versus false alarm characterisation of a vision-based airborne dim-target collision detection system

This paper presents a preliminary flight test based detection range versus false alarm performance characterisation of a morphological-hidden Markov model filtering approach to vision-based airborne dim-target collision detection. On the basis of compelling in-flight collision scenario data, we calculate system operating characteristic (SOC) curves that concisely illustrate the detection range versus false alarm rate performance design trade-offs. These preliminary SOC curves provide a more complete dim-target detection performance description than previous studies (due to the experimental difficulties involved, previous studies have been limited to very short flight data sample sets and hence have not been able to quantify false alarm behaviour). The preliminary investigation here is based on data collected from 4 controlled collision encounters and supporting non-target flight data. This study suggests head-on detection ranges of approximately 2.22 km under blue sky background conditions (1.26 km in cluttered background conditions), whilst experiencing false alarms at a rate less than 1.7 false alarms/hour (ie. less than once every 36 minutes). Further data collection is currently in progress.

Field-of-view, detection range, and false alarm trade-offs in vision-based aircraft detection

This paper presents a survey of previously presented vision based aircraft detection flight test, and then presents new flight test results examining the impact of camera field-of view choice on the detection range and false alarm rate characteristics of a vision-based aircraft detection technique. Using data collected from approaching aircraft, we examine the impact of camera fieldof-view choice and confirm that, when aiming for similar levels of detection confidence, an improvement in detection range can be obtained by choosing a smaller effective field-of-view (in terms of degrees per pixel).

The maturity model concept as framework for assessing the capability of higher education institutions to address student engagement, success and retention : new horizon or false dawn?

While the engagement, success and retention of first year students are ongoing issues in higher education, they are currently of considerable and increasing importance as the pressures on teaching and learning from the new standards framework and performance funding intensifies. This Nuts & Bolts presentation introduces the concept of a maturity model and its application to the assessment of the capability of higher education institutions to address student engagement, success and retention. Participants will be provided with (a) a concise description of the concept and features of a maturity model; and (b) the opportunity to explore the potential application of maturity models (i) to the management of student engagement and retention programs and strategies within an institution and (ii) to the improvement of these features by benchmarking across the sector.

Getting in the door : the voluntary provision of accessible housing in Australia

This paper outlines the methodology used in a PhD qualitative research study on the agency of the housing industry in Australia in the provision of accessible housing. Previous studies have identified the need for an increased supply of accessible housing to optimise the inclusion and participation of all people, yet the demand for accessible housing by new home buyers is minimal and voluntary strategies to increase supply have typically failed. In 2010, housing industry leaders agreed to adopt a national voluntary access guideline for housing (Livable Housing Design) and a strategy to provide minimum access features in all new housing by 2020. This study explores the “escaped” phenomenon; how individual agents within the housing industry respond to such initiatives. As the paper is written mid-study it uses a preliminary theme in the findings, that is, minimal demand, to illustrate the methodology of the research.

False-colour spectrograms of long duration acoustic recordings

Acoustic recordings of the environment are an important aid to ecologists monitoring biodiversity and environmental health. However, rapid advances in recording technology, storage and computing make it possible to accumulate thousands of hours of recordings, of which, ecologists can only listen to a small fraction. The big-data challenge is to visualize the content of long-duration audio recordings on multiple scales, from hours, days, months to years. The visualization should facilitate navigation and yield ecologically meaningful information. Our approach is to extract (at one minute resolution) acoustic indices which reflect content of ecological interest. An acoustic index is a statistic that summarizes some aspect of the distribution of acoustic energy in a recording. We combine indices to produce false-colour images that reveal acoustic content and facilitate navigation through recordings that are months or even years in duration.

Effects of different surfaces on the perception of prey-generated noise by the Indian false vampire bat Megaderma lyra.

The low- and high-frequency components of a rustling sound, created when prey (freshly killed frog) was jerkily pulled on dry and wet sandy floors and asbestos, were recorded and played back to individual Indian false vampire bats (Megaderma lyra). Megaderma lyra responded with flight toward the speakers and captured dead frogs, that were kept as reward. The spectral peaks were at 8.6, 7.1 and 6.8 kHz for the low-frequency components of the sounds created at the dry, asbestos and wet floors, respectively. The spectral peaks for the high-frequency sounds created on the respective floors were at 36.8,27.2 and 23.3 kHz. The sound from the dry floor was more intense than that of from the other two substrata. Prey movements that generated sonic or ultrasonic sounds were both sufficient and necessary for the bats to detect and capture prey. The number of successful prey captures was significantly greater for the dry floor sound, especially to its high-frequency components. Bat-responses were low to the wet floor and moderate to the asbestos floor sounds. The bats did not respond to the sound of unrecorded parts of the tape. Even though the bats flew toward the speakers when the prey generated sounds were played back and captured the dead frogs we cannot rule out the possibility of M. lyra using echolocation to localize prey. However, the study indicates that prey that move on dry sandy floor are more vulnerable to predation by M. lyra.

Beyond the hospital door : a retrospective, cohort study of associations between birthing in the public or private sector and women’s postpartum care

Background In Australia, maternity care is available through universal coverage and a parallel, competitive private health insurance system. Differences between sectors in antenatal and intrapartum care and associated outcomes are well documented but few studies have investigated differences in postpartum care following hospital discharge and their impact on maternal satisfaction and confidence. Methods Women who birthed in Queensland, Australia from February to May 2010 were mailed a self-report survey 4 months postpartum. Regression analysis was used to determine associations between sector of birth and postpartum care, and whether postpartum care experiences explained sector differences in postpartum well-being (satisfaction, parenting confidence and feeling depressed). Results Women who birthed in the public sector had higher odds of health professional contact in the first 10 days post-discharge and satisfaction with the amount of postpartum care. After adjusting for demographic and postpartum contact variables, sector of birth no longer had an impact on satisfaction (AOR 0.95, 99% CI 0.78-1.31), but any form of health professional contact did. Women who had a care provider’s 24 hour contact details had higher odds of being satisfied (AOR 3.64, 95% CI 3.00-4.42) and confident (AOR 1.34, 95% CI 1.08- 1.65). Conclusion Women who birthed in the public sector appeared more satisfied because they had higher odds of receiving contact from a health professional within 10 days post-discharge. All women should have an opportunity to speak to and/or see a doctor, midwife or nurse in the first 10 days at home, and the details of a person they can contact 24 hours a day.

Mobile medical applications for melanoma risk assessment: False assurance or valuable tool?

With the smartphone revolution, consumer-focused mobile medical applications (apps) have flooded the market without restriction. We searched the market for commercially available apps on all mobile platforms that could provide automated risk analysis of the most serious skin cancer, melanoma. We tested 5 relevant apps against 15 images of previously excised skin lesions and compared the apps' risk grades to the known histopathologic diagnosis of the lesions. Two of the apps did not identify any of the melanomas. The remaining 3 apps obtained 80% sensitivity for melanoma risk identification; specificities for the 5 apps ranged from 20%-100%. Each app provided its own grading and recommendation scale and included a disclaimer recommending regular dermatologist evaluation regardless of the analysis outcome. The results indicate that autonomous lesion analysis is not yet ready for use as a triage tool. More concerning is the lack of restrictions and regulations for these applications.

‘The door creaked shut’: The new breach of bail offence for youth in Queensland

As part of the 2014 amendments to the Youth Justice Act 1992 (Qld) the previous Queensland government introduced a new breach of bail offence and a reverse onus provision in relation to the new offence. Also included in the raft of amendments was a provision removing the internationally accepted principle that, in relation to young offenders, detention should be used as ‘a last resort’. This article argues that these changes are likely to increase the entrenchment of young people within the criminal justice system.
