Inner ear malformations in siblings presenting with vestibular symptoms in early childhood
IRT Butler, RY Seedat
South African Journal of Child Health , 2011,
Abstract: Introduction. Although the association between inner ear abnormalities and progressive sensorineural hearing loss is well known, vestibular signs or loss of vestibular function in these patients are often unrecognised by medical practitioners. Case report. We report on two siblings with identical inner ear malformations, with special reference to the vestibular symptoms they displayed, as well as the rapid decline in hearing they both experienced in early childhood. We provide a brief overview of the latest classification of these inner ear defects as well as a review of the literature pertaining to children with inner ear malformations presenting with vestibular symptoms. Conclusion. Gross anatomical defects of the inner ear are present in approximately 20% of cases of congenital hearing loss. These defects may result in a rapidly progressive hearing loss. Any child presenting with vestibular symptoms should be referred for an audiological assessment.
Performance Analysis of "WBC over DVB-H" Link Layer
Ji Zhanlin,Ganchev Ivan,O'Droma Máirtín
EURASIP Journal on Wireless Communications and Networking , 2010,
Abstract: This paper presents two novel smart cross-layer error-control coding schemes for improving the error protection of service advertisements that are broadcast to mobile terminals on wireless billboard channels (WBCs) established over a digital video broadcast-handheld (DVB-H) infrastructure. These are the smart section erasure (SSE) and smart transport stream erasure (STSE) schemes, which are jointly executed by the link layer and service layer cross-layer algorithms. The new schemes are analysed and compared to existing schemes. The solution enables the "WBC over DVB-H" system to operate with good flexibility, and in a more reliable way and with greater throughput efficiency than the standard IP datacasting supported in DVB-H.
"WBC over DVB-H" Testbed Design, Development and Results
Ji Zhanlin,Ganchev Ivan,O'Droma Máirtín
EURASIP Journal on Wireless Communications and Networking , 2010,
Abstract: The wireless billboard channels (WBCs) are integral part of the ubiquitous consumer wireless world (UCWW)—a wireless next generation network proposal. The WBCs are used by the service providers to broadcast advertisements of their (wireless) services to the mobile terminals so that the mobile users may discover and associate with the "best" services following the user-driven ''always best connected and best served'' paradigm. A three-layer system architecture of WBCs established over the digital video broadcasting-handheld (DVB-H) standard is presented. The design and development of a corresponding ''WBC over DVB-H'' experimental testbed are described. Various results obtained from the testbed are presented and explained.
O parentesco é sempre tido como heterossexual?
Butler, Judith;
Cadernos Pagu , 2003, DOI: 10.1590/S0104-83332003000200010
Abstract: using the french debate on the gay marriage as a starting point, the author concludes that either answer to the question, both the "yes" and the "no", work to circumscribe a much more complex reality and considers the political and theoretical risks of so doing.
O limbo de Guantánamo
Butler, Judith;
Novos Estudos - CEBRAP , 2007, DOI: 10.1590/S0101-33002007000100011
Abstract: the article discusses the legal statute of the united states? procedures concerning taliban detainees at guantánamo bay. when questioning the refusal of american authorities to concede these prisoners the status of "prisoners of war" in the terms of the geneva conventions, the author claims a critical revision of this international protocol.
Desdiagnosticando o gênero
Butler, Judith;
Physis: Revista de Saúde Coletiva , 2009, DOI: 10.1590/S0103-73312009000100006
Abstract: the paper takes stock of the current debate on the undoing of the pathologization process of transsexuality in the united states. the author asserts that, if, on one hand, the diagnosis of gender identity disorder is still considered worthwhile to be maintained as to ease the financial means to the transition, on the other hand, opposing the diagnosis is also needed in that the diagnosis presumes as a mental illness what should rather be understood as a possibility among many of gender self-determination. bringing to light how complex and paradoxal this debate is, she contends that these two stands should, however, not be considered fully contradictory since, in her viewpoint, transautonomy will not be achieved as long as a legal, medical and social supportive net is not brought about, which only will really make it possible that one lives a transsexual life.

Ecospirituality in the Age of Technological Overkill: Body-Time Reclamation in the Fiction of Alan Lightman and Don DeLillo
Jonathan Butler
Ecozon@ : European Journal of Literature, Culture and Environment , 2011,
Abstract: In exploring the link between ecospirituality and the hard sciences, I argue that theformer provides a much-needed complement to the latter. The fragmentation ofdisciplinary pursuits fostered by the Enlightenment and by the continued progress ofunquestioned technological advance as an end in itself finds its ultimate expression inour current disconnection from the natural world, from each other, and even fromourselves. As a corrective to such disconnection, ecospiritual impulses emerge in anattempt to unify a discombobulated subject, a self so fragmented by the multiplenarratival requirements of a communication-obsessed age (where we can be reached bycell phone, regular phone, multiple email addresses, Facebook, and other social media)that the "contemplative" facet of being human within the rhythms of the natural worldis all but obscured-indeed, is hardly given the requisite environment in which tofunction. Against this over-reliance on technology, on where the hard sciences have ledus, ecospirituality emerges as a balm for the terrorized human spirit. Don DeLillo'srecent novel Point Omega documents this poignantly. His narrator speaks of the "usualterror" of cities with their "endless counting down," with people constantly checkingtheir watches and other time-keeping devices. DeLillo's protagonist moves to the desertwhere "geological time" becomes the paradigm through which a restorative calm isgenerated. Alan Lightman's fiction proves even more relentless in its depiction of thedissociation engendered by an over-reliance on technology. Lightman's protagonist inThe Diagnosis is an information trader who suffers a breakdown and is only restored towell-being through a re-acquaintance with his own natural body rhythms along withthose of the natural world. Many of the characters in the short-story collectionEinstein's Dreams also find that a connection to nature counteracts the senselesscompetition of a consumer-driven, technologically-enhanced world.
Estrogen in the Water: Impacts of Sewage Wastewater on Feminization and Vitellogenin Expression in Male Fathead Minnows (Pimephales promelas)
Lexis Butler
JPUR : Journal of Purdue Undergraduate Research , 2012,
Abstract: Estrogenic compounds (primarily from substances likebirth control drugs) are commonly found in domesticwastewater effluent. These compounds can feminize malefish (e.g., decrease male secondary sex characteristics),reducing competitive advantage during spawning.Exposure to estrogenic chemicals can also lead to theproduction of female-specific proteins such as vitellogenin(VTG). VTG is a yolk-precursor protein synthesizedby the liver of egg-laying females after the stimuli ofestrogen. We hypothesize that upon exposure to estrogencontainingwastewater, adult male fathead minnows(Pimephales promelas) will express this female-specificprotein. Adult males were caged at two different sites inthe West Fork of the White River. The downstreamgroup was placed directly below the outflow from theMuncie Water Pollution Control Facility (MWPCF),while another group (upstream) was placed 0.25 kmupstream from MWPCF. Following a two-week exposure,secondary sex characteristics were examined, and liverswere processed through quantitative polymerasechainreaction (qPCR) to determine expression of VTG. Whileno significant differences resulted from comparison ofsecondary sex characteristics between the study groups,downstream males showed a VTG up-regulation of~ 14-fold (SD = 2.4) when compared to the control group.These results are in agreement with a previous studyin this same area that found “feminization” of nativepopulations of bluntnose minnows (Pimephales notatus).The “estrogenic” compounds that elicited this responseremain unknown.
