Use of an auditory looming task to test infants' sensitivity to sound pressure level as an auditory distance cue

This study describes how an auditory looming technique was used to investigate 4-to 6-month-old infants' sensitivity to sound pressure level (SPL) as an auditory distance cue. Thirty-two infants were tested in complete darkness and presented with auditory stimuli that underwent unidirectional variations in SPL (40–70dB). The rate at which SPL was varied during the course of trials (past vs. slow) was manipulated by varying trial length (5s vs. 10s).

All that is dark can become white: the rules of the game in Bend it Like Beckham

The “light” and uplifting film, Bend it Like Beckham (2002), is deconstructed to expose its passive ideologies that equate physical darkness with regressive cultural and social outlooks and practices. While Bend it Like Beckham constructs itself as a modern fairy tale of a girl achieving her dream of athletic opportunity and success (with a nice side-dish of romance), the film’s privileging of whiteness is both a cultural and a gendered norm that must be desired and achieved before that dream may come true.

Being resilient as described by people who experience mental illness

Aim: The purpose of this research was to explore resilience as described by consumers of mental health services in Australia who have experienced mental illness.

Background: Most qualitative research pertaining to resilience has focused on child and adolescent groups. In relation to the Australian context there appears to be a paucity of qualitative studies on resilience and the experience of mental illness.

Method: The study utilized a phenomenological approach elucidated by Colaizzi as the philosophical underpinnings of the study. In keeping with Colaizzi’s (1978) approach to inquiry, information was gathered through in-depth, semi-structured individual interviews. Information analysis utilised Colaizzi’s (1978) original seven-step approach with the inclusion of two additional steps, making this study’s analysis a nine step process.

Findings: Emergent themes explicated from participant transcripts follow: Universality, Acceptance, Naming and knowing, Faith, Hope, Being the fool and, Striking a balance, Having meaning and meaningful relationships, and ‘Just doing it’. The emergent conceptualisation which encapsulated the themes was; Viewing life from the ridge with eyes wide open. - choosing to walk through the darkness all the while knowing the risks and dangers ahead and making a decision for life amid ever-present hardships.

Conclusion: The findings of this study suggest being resilient can be learnt and therefore, should be a fundamental consideration in guiding therapeutic interventions within the context of clinical practice.

Fictional endstates

Studies the intellectual in power striving to realise the universal State or Empire. Examines this theme through the medium of four fictional narratives: Yevgeny Zamyatin's We, Aldous Huxley's Brave new world, Arthur Koestler's Heart of darkness, and George Orwell's Nineteen eighty-four. The hypothesis of the inquiry is that all four of these texts provide fictional redescriptions of a crisis of confidence in the Enlightenment ideal of progress.

Methods of coating textiles with soluble conducting polymers

Soluble conducting alkyl polypyrrole polymers have been applied by either chemical polymerization of the 3-alkyl monomers or direct application of polymer emulsion to the surface. Solution, vapor and spray polymerization methods of coating poly(3-alkylpyrroles) to the surface of woven wool fabrics are explored. Conductive textile samples have also been prepared by applying emulsions of soluble prepolymerized 3-alkylpyrrole to the fabric surface. Direct applications of a conductive paint to the textile surface eliminate the exposure of the substrate to damaging oxidizing agents which allow the coating of more sensitive and delicate substrates. All textiles produced are tested for abrasion resistance and conductivity. For alkyl polypyrrole coated fabrics, the optimum carbon chain lengths are between n=10 and n=14, which result in optimum values of conductivity and solubility. The darkness of the tone is inversely related to the surface resistivity of the resulting conductive fabric. Therefore, deep black coatings have low resistivity whereas light gray coatings on a white fabric surface have higher surface resistivity. Longer alkyl chains result in higher surface resistivity in fabrics. The conductive coating of poly(3-decanylpyrrole) on the textile surface has a better abrasion resistance compared to that of an unsubstituted polypyrrole coating.

A method for tracking rats in a complex and completely dark environment using computerized video analysis

The automated tracking of rodents in open field environments has become a standard laboratory technique for the investigation of the effects of drugs, novel therapeutic interventions and genetic mutations on behavior. Here, we develop an extension of this technique that permits tracking in full darkness through a complex (‘enriched’) environment comprising naturalistic structures such as tunnels and hides. To eliminate unwanted light reflections and tape noise, we developed a unique video filter that combines the advantages of differential and non-differential filtering. This filter enabled the tracking of albino rats against a relatively dark background to an accuracy of approximately 97% compared to hand tracking of the same animal, irrespective of whether the rat was inside a hide box or tunnel or out in the open field. The system as a whole can be easily deployed using standard PCs and inexpensive infrared cameras and lights.

The world-swimmers

For days now you have been driving across unbroken grassland, which you know you’ll never be able to leave behind forever, no matter how fast you might go, or however deep into the night you persist in your journey. The northern coast of your country is far in the distance and darkness, yet nothing is clearer to you than the knowledge that the plain you once in a while spit into will surely not disappear when it gets to the water. You have faith it will move without interruption through the breakers, even picking up speed across the ocean, until there is no more ocean—and with all the more reality if it takes on a form you could not even begin to comprehend. After so much confusion—the wrack of entire cities on sickening flats of sand—this alone seems certain.

Dreamweavers

Dreamweavers is a touring show Curated by Simon Gregg at the Gippsland Regional Gallery, touring Nationally from 2011 until April 2013.

The exhibition explores the contemporary preoccupation for the Fantastic through a range of national and international art practices, that are united by an enduring fascination with darkness and dark places. Dreamweavers is a multi-sensory experience that is more like entering another world than an art exhibition. It combines sculpture, digital media, photography and painting, in an intoxicating visual feast.

Dreamweavers features the work of six artists. James Gleeson (1915-2008) was Australia’s pre-eminent Surrealist, and one of the country’s most acclaimed twentieth century artists. In his work massive, heaving and largely unidentifiable forms meld with apocalyptic skies and earth in twisted biomorphic shapes.

i1234m

In experimental film-artist Dirk De Bruyn’s work, these gestures of syntactical erasure can be understood as a poetic practice which seeks to grasp preverbal early childhood states – an (inevitably futile) attempt to excise meaning from experiences, before language and its attendant comprehension of the world. De Bruyn attributes this impulse to his early immigration from The Netherlands to Australia, and the confusion he experienced in the consequent liminal space between cultures, identities and languages. His tumultuous performances, which typically begin and end in darkness, combine urgent vocal utterances – hollering, screaming and chanting – with the sumptuous illumination of projected film. De Bruyn’s vocalisations meld with and amplify the images’ blooming fields of colour and intricately layered, hand-animated imagery. At Gertrude, Dirk will perform a new work for three 16mm projectors and voice entitled ‘i1234m’.

Darwin after dark: illuminating suburban atmospheres

In Australian cities, culturally diverse suburban landscapes are often sensed as discomforting sites of fear and anxiety, particularly after dark. Imagined risks of encounters with bodies of colour easily policed during the day when vision is clear, but who escape biopolitical regimes of securitisation and surveillance at night contribute to such atmospheric qualities of place. These affective atmospheres of fear and anxiety that haunt bodies and limit their ability to inhabit public space, however, can provide a sense of freedom for bodies who claim suburban spaces of darkness through tactile and sonic senses. This paper draws on the contemporary literature on affective atmospheres to show how racialised Indigenous and asylum seeker bodies become present in different ways in suburban places in Darwin after dark. The paper focuses on two events – spontaneous dancing to Indigenous music at Mindil beach market and a Vigil commemorating asylum seeker lives in a suburban courtyard. Drawing on ethnographic research I explore these affective intervention that illuminate dark suburban atmospheres in Darwin. Such interventions that draw attention to the attunement of bodies to difference unsettle biopolitical regimes that victimise and patronise visible non-white bodies and contribute to rethinking racism and darkness in suburban Darwin and the Top End.

Headless and unborn, or the Baphomet restored: interfering with Bataille and Masson’s image of the Acephale

At a certain period in European intellectual history, a comparatively large number of artists and intel- lectuals – arguably the most important thinkers and artists of the times – were all involved to a greater or lesser degree in the envisioning of a new myth that might lead European civilization out of the gathering darkness of fascism, a myth they hoped would pro- voke the total and radical transformation of society and culture.

Synchronization by low-amplitude light-dark cycles of 24-hour pineal and plasma melatonin rhythms of hatchling European starlings (Sturnus vulgaris)

In young European starlings, as in other avian species, high-amplitude 24-hr rhythms in plasma and pineal melatonin are already present around the time of hatching. In chickens this rhythmicity results at least partly from the light sensitivity of the melatonin-producing and -secreting system. In contrast to the chicken, the starling is a hole-nesting bird, and it seemed questionable whether the low light intensities in the nest are sufficient to synchronize perinatal melatonin rhythms. We therefore exposed starling eggs to light cycles roughly simulating those measured in nest-boxes, i.e., an 11-hr phase of complete darkness and a 13-hr phase consisting of 15 min of dim light (10 lux) alternating with 30 min of darkness. For one group the photophase lasted from 0600 to 1900 hr; for the other group the photophase lasted from 1800 to 0700 hr. In approximately 10-hr-old hatchlings of both groups, plasma and pineal melatonin concentrations were high during the dark phase and low during the light phase. We conclude that perinatal low-amplitude light intensity changes of the kind experienced by hatching starlings in the field are sufficient for synchronizing the melatonin-producing and -secreting system in the pineal and possibly other organs.

Fatores da administração do sistema penitenciário do Rio de Janeiro que os impedem de cumprirem com sua missão de recuperação do detento?

Since some years ago, the penitentiany systen of Rio de Janeiro is going through the nuest sendus administrative crisis,leading more and more to chaotic situations, over imagined before by homan being. Nowadays all the factors and components of the existing models are still medievaIs, and even distant fron the human needs. The daily life ofthe condemned is a sway betuen lack of hygiene, disrespect to homan rigts, lack of modem corrective practices and also, lack of psychological support. How, then can me demand from the state ( Govemment) the rehabilitation of the imprisoned and their preparation to face society if they are treated manny times as victins of this same society? This society impose a life style enjoyed only by a privileged social class which forget about then when sent to the darkness. Many of then, join the penitentary systen because of minor crimes, and when they serve their tem, um for funately they go back to prison accused for move violent crimes. The penitentian models haven't developed the same way the society where they worked at has. There, the present brazilian penitentiary model has showed obsolete and inefficient alone its principal mission ofrehabilitation and re - education ofthe imprisoned. Our main objetive will be the construction and analysis of the penitential administrative model, as being able to fullfill the necesity of the penitentiary administrator (Manager). Analy zing on a specific reasoning which focus showld not be that of the theories and isolated projects of the topic, we will develop a progran far form religions, judiciary on political technics by building na administrtive penitentiary model strictly professional where we coul a have a deep analysis of the topic. We will try to approach the aspects of organization existing to day inorder to understand them and criate, a model wich will adjust betten to the necesitives of this thesis.
