Grado, Mercedes de. "La rebelión de las sirenas : identidad y debate feminista en la narrativa de Adelaida García Morales." Thesis, Durham University, 2002. http://etheses.dur.ac.uk/3837/.
Full textAbstract:
This doctoral thesis analyses the types of feminine identity represented in Adelaida Garcia Morales' works. It examines as well how these subjectivities are constituted and points out that this Spanish writer's narrative proposes alternative symbolic representations of Spanish women and new feminine identities who are not framed according to patriarchal standards. Furthermore, this study highlights how Garcia Morales' novels and short stories constitute what it has been labelled as "fiction of debate". That is, they represent different ideas and feminist concepts proposed by the two main Spanish feminist approaches: feminism of difference and feminism of equality. The texts analyzed in these theses provide a valuable channel of communication, and create a forum for both airing and debating the main concerns of Spanish women and issues at stake during the 80's and 90's. This study will follow a literary feminist approach, which focuses on the historical and social frameworks of Garcia Morales work's production as well as contextualizes her narrative with reference to the recent Spanish social and political history. Therefore, this study points out the dialectical relationship between texts and ideological structures, which allows an account of the interrelationships between literature and feminist politics.

Full textAbstract:
Memoria (licenciado en ciencias jurídicas y sociales)Esta tesis presenta una reflexión metateórica de la historia de la filosofía del derecho de los siglos XX y XXI al interior de la tradición analítica. Para dicho propósito se divide en tres ejes argumentativos. El primero presenta la elucidación de la noción de tradición analítica en filosofía, a partir de la distinción entre “tradiciones y concepciones filosóficas” propuesta por M. E. Orellana Benado, con el fin de dar cuenta de sus orígenes, rasgos distintivos y discusiones más relevantes. El segundo ofrece una comprensión iusfilosófica de la tradición analítica en el siglo XX. Sobre la base de: la Teoría Pura del Derecho (1934) de Hans Kelsen y El Concepto de Derecho (1961) de H. L. A. Hart. Analizando las dos aproximaciones metodológicas de este último (al derecho como sociología descriptiva y como teoría jurídica analítica) y sus puntos centrales. Finalmente, revisa las consecuencias que trajo la publicación de la segunda edición de El Concepto de Derecho (1994) con el Postscript, añadido por sus editores, texto en el que Hart responde a sus críticos. El tercer eje argumentativo muestra en dos partes el desarrollo de la filosofía jurídica analítica de los tres primeros lustros del siglo XXI. Una de ellas considera la importancia y actualidad de los proyectos de Kelsen y Hart, mientras que la otra indagará en el surgimiento de nuevas concepciones iusfilosóficas como el naturalismo jurídico, el pragmatismo jurídico, el Law & Economics y los estudios críticos del derecho

Full textAbstract:
Recent books by Alan Bloom and Alasdair MacIntyre have argued that liberal individualism is inadequate to a full moral existence. Bloom claims that our lives could be so much richer if we recognized the creative force of 'prejudices' and acknowledged that culture needs just such a creative force if it is to flourish. MacIntyre claims that individual identity is embedded in the particular cultural tradition of which each individual is a part. He goes on to develop the argument that each person's moral understanding is necessarily bounded by his own tradition and that moral membership in some such tradition is a precondition of being able to understand the moral arguments of any tradition. MacIntyre also argues that the language of moral debate suffers from meaning incommensurability because the underlying rationale for the arguments that are framed within each tradition reflect different beliefs about rationality. Both Bloom and MacIntyre can be interpreted in a way that depicts them as complementary members of a school of thought known as 'communitarianism'. This paper takes the view that the version of communitarianism formed by the conjunction of the major premises of Bloom and MacIntyre is based on an epistemological error. It begins with a brief exploration of the genesis of the concept of modern individualism using De Tocqueville as the point of departure. The paper attempts to illustrate the Tocquevillean theme of "freedom as interdependency" of rational individuals. (Abstract shortened by UMI.)

Resumo: Rede Neural Artificial (RNA) é um modelo que tenta emular uma Rede Neural Biológica. A área de RNA tem se mostrado bastante promissora, o que pode ser comprovado pela quantidade de trabalhos publicados e de eventos científicos. Mas para que as RNAs atinjam o escopo de aplicações desejado, muitas de suas limitações atuais terão que ser superadas. Ainda não é claro e bem estabelecido o funcionamento das RNAs, não existem metodologias boas e completas para a utilização das mesmas em aplicações, isto é, metodologias que diante de um problema específico a ser resolvido, indiquem qual a topologia de rede, o algoritmo de aprendizagem e a amostragem de informações adequadas ao funcionamento desejado. Em não se tendo uma metodologia que indique a combinação ótima dos elementos de uma RNA para uma determinada aplicação, resta aos usuários a opção de partir de uma base teórica e, utilizando-se de métodos empíricos, ir formando regras individuais de como conseguir as melhores combinações dos elementos formadores da rede. Esta técnica, porém, apresenta muitas dificuldades em sua realização devido à grande quantidade de variáveis que precisam ser avaliadas durante todo o processo de desenvolvimento da rede. O presente trabalho busca facilitar o entendimento do funcionamento das RNAs através da familiarização do usuário com os seus elementos formadores. Foi desenvolvido um simulador de RNAs, denominado Sirena, que através de sua interface gráfica procura minimizar a dificuldade de entendimento dos processos de baixo nível realizados pelas RNAs. Durante o processo de simulação pode-se ter acesso a diversas representações, tanto qualitativas quanto quantitativas, que visam refletir as alterações que ocorrem na rede rias fases de aprendizagem e inferência.
Abstract: Artificial Neural Net (ANN) is a model that emulates a Biological Neural Net. The ANN field has showed very promising which can be verified by the number of published papers and scientific events. In spite, to reach the desired ANN applications scope, many of ANN current limitations have to be overcome since it is not yet and well established the ANN functioning . There is no good and complete methodologies for construct ANN applications, i.e., for a specific problem to be solved, no methodology indicates what the net topology is, the learning algorithm and the sample of information suitable to the desired performance. If there is no methodology that indicates the better combination of the ANN elements to a specific application, the users have the option to start from a theoretical base and, by using empirical methods, begin constructing personal rules that indicates. the better combination of neural elements. The execution of this technique is difficulty because the number of variables that need to be evaluated during the net development process The focus of this work is facilitate the understanding of the ANN functioning through the user familiarization with its elements. A ANN simulator named Sirena was developed and its graphical interface aim to minimize the understanding difficulties of the low level processes executed by ANNs. During the simulation process one can access to several qualitative and quantitative representations that reflect the net alterations in the learning and inference phases.

Full textAbstract:
This inquiry is a two-tongued performance as research project asking "Why was the voice of the Sirens deadly?" and "How can the Sirens inform contemporary feminist theatre praxis?". The two questions in constant dialectic have been explored in a written dissertation as well as in a one-hour original and ensemble performance called The Quivering: a Matter of Life and Death. Analysing references in mythology, art and history, the written component suggests how the Siren's sonic qualities are manifest in distinct cultural icons and embodied by actual female performers. Four Siren vocalities are identified and theorised: The Monster vocality is evidenced in the figure of the femme fatale; the Lamenter exists in traditional funerary singers and contemporary torch songs; the sound of the Diva is heard in the opera queen; and the Lullaby Maker acoustics oscillate between the banter of Mother Goose and the 'red hot mamas' of the blues. Pursuing what is deadly about each of these embodied voices, the thesis articulates why female sound, like the Siren song of knowledge, is so ambivalently received - its evocation of otherness (Monster), liminality (Lamenter), jouissance (Diva) and contra-diction (Lullaby Maker) is both feared and revered. These four vocalities have grown in and out of The Quivering, a performance odyssey that has interrogated aesthetic, content, characterisation, narrative and devising practice, all with an ear to the Siren's 'deadly' sonority. Subverting portrayals of death as a woman and a taboo, its comic-tragic heroines exist in a liminal landscape as lamenters who confront and facilitate the audience's death passage. In counterpoint to Homeric legacy, it has been designed as an open text, which, combined with its heightened physicality and musicality, make for an 'other' aesthetic or contemporary Siren 'song'. The Quivering is pitched at the same tone as the distilled Siren vocalities or 'blue notes', and, as a performance as research project, also re-sounds provocatively within traditional academic discourse. The 'deadliness' of the female voice, in myth, in theory and in performance thus resides in its dissolution of logos and certainty. It quivers with the pleasure and trauma of a corporeal jouissance that exceeds narrative and linguistic frames with its full-bodied, acoustic and imagistic resonance.

Full textAbstract:
This thesis examines three works: Margaret Atwood's The Robber Bride and Alias Grace, and Angela Carter's Nights at the Circus. All three novels feature female characters that contain elements or myth fragments of mermaids and sirens. The thesis asserts that the images of the mermaid and siren have undergone a gradual process of change, from literal mythical figures, to metaphorical images, and then to figures or myth fragments that reference the original mythical figures. The persistence of these female half-human images points to an underlying rationale that is independent of historical and cultural factors. Using feminist psychoanalytic theoretical frameworks, the thesis identifies the existence of the siren/mermaid myth fragments that are used as a means to construct the category of the 'bad' woman. It then identifies the function that these references serve in the narrative and in the broader context of both Victorian and contemporary societies. The thesis postulates the origin of the mermaid and siren myths as stemming from the ambivalent relationship that the male infant forms with the mother as he develops an identity as an individual. Finally, the thesis discusses the manner in which Atwood and Carter build on this foundation to deconstruct the binary oppositions that disadvantage women and to expand the category of female.

Full textAbstract:
Une approche télescopique par une enquête de très longue durée et une analyse microscopique des cas localisés révèlent la dimension transculturelle -à la fois diachronique et synchronique- des réemplois populaires de l'image de la sirène. Les cas étudiés sont très éloignés dans le temps et dans l'espace: Mami Wata dans l'Afrique post-coloniale; un corpus d'amulettes européennes et une sirène nourrice au Moyen-Âge; des sirènes séductrices dans la Grèce ancienne. L'étude des intentionnalités activées par ce corpus d'images-objets suit les branchements historiques qui relient ces cas et souligne, dans un parcours régressif, l'étendue historique des dynamiques de métissage culturel. Chaque adaptation culturelle de l'image de la sirène, loin de se présenter comme la survivance d'une tradition se définit comme une invention novatrice s'appropriant d'une héritage sélectionné par une mémoire active et irrévérencieuse. Cette recomposition constante sauvegarde aunsi la vitalité du mytheA comprehensive long-term approach and a microscopic analysis of circumscribed cases highlight the transcultural dimension -both diachronically and synchronically- of re-employment of the image of the siren and mermaid in folklore. Examples are drawn from different places at different points in history: Mami Wata in post-colonial Africa, a corpus of European charms; a nursing mermaid in the Middle Ages; seductive sirens in Ancient Greece. The study of the agency underpinning a corpus of image-objects from those contexts follows a description of the historical connections linking those cases and underlines, by following a regressive approach, the historical depth of the dynamics of cultural hybridization. In non way does each cultural embedding of the siren and mermaid myth present itself as the mere survival of a tradition. Rather it adds innovation to an active and playful memory, thus safeguarding the myth's vitality

Full textAbstract:
Successful implementation of advanced electrical power generation technology into the global marketplace requires at least two fundamental ideals: cost effectiveness and the guarantee of public safety. These requirements can be met by thorough design and development of technologies in which safety is emphasized and demonstrated. A detailed understanding of the many physical processes and their synergistic effects in a complicated fusion energy system is necessary for a defensible safety analysis. One general area of concern for fusion devices is the production of particulate, often referred to as dust or aerosol, from material exposed to high energy density fusion plasma. This dust may be radiologically activated and/or chemically toxic, and, if released to the environment, could become a hazard to the public. The goal of this investigation was to provide insight into the production and transport of particulate generated during the event of extreme heat loads to surfaces directly exposed to high energy density plasma. A step towards achieving this goal was an experiment campaign carried out with the Surface InteRaction Experiment at North Carolina State (SIRENS), a facility used for high heat flux experiments. These experiments involved exposing various materials, including copper, stainless steel 316, tungsten, aluminum, graphite (carbon), and mixtures of carbon and metals, to the high energy density plasma of the SIRENS source section. Material mobilized as a result of this exposure was collected from a controlled expansion chamber and analyzed to determine physical characteristics important to safety analyses (e.g., particulate shape, size, chemical composition, and total mobilized mass). Key results from metal-only experiments were: the particles were generally spherical and solid with some agglomeration, greater numbers of particles were collected at increasing distances from the source section, and the count median diameter of the measured particle size distributions were of similar value at different positions in the expansion chamber, although the standard deviation was found to increase with increasing distances from the source section, and the average count median diameters were 0.75 micron for different metals. Important results from the carbon and carbon/metals tests were: particle size distributions for graphite tests were bi-modal (i.e. two distributions were present in the particle population), particles were generally smaller than those from metals-only tests (average of 0.3 micron), and the individual particles were found to contain both carbon and metal material. An associated step towards the goal involved development of an integrated mechanistic model to understand the role of different particulate phenomena in the overall behavior observed in the experiment. This required a detailed examination of plasma/fluid behavior in the plasma source section, fluid behavior in the expansion chamber, and mechanisms responsible for particulate generation and growth. The model developed in this work represents the first time integration of these phenomena and was used to simulate mobilization experiments in SIRENS. Comparison of simulation results with experiment observations provides an understanding of the physical mechanisms forming the particulate and indicates if mechanisms other than those in the model were present in the experiment. Key results from this comparison were: the predicted amount of mass mobilized from the source section was generally much lower than that measured, the calculated and measured particle count median diameters were similar at various locations in the expansion chamber, and the measured standard deviations were larger than those predicted by the model. These results implicate that other mechanisms (e.g., mobilization of melted material) in addition to ablation were responsible for mass removal in the source section, a large number of the measured particles were formed by modeled mechanisms of nucleation and growth, and, as indicated by the large measured standard deviations, the larger particles found in the measurement were from an aerosol source not included in the model. From this model, a detailed understanding of the production of primary particles from the interaction of a high energy density plasma and a solid material surface has been achieved. Enhancements to the existing model and improved/extended experimental tests will yield a more sophisticated mechanistic model for particulate production in a fusion reactor.

Full textAbstract:
This thesis challenges the traditional view of the 'femme fatale' as merely a dangerous and ravenous sexual predator who leads men into ruination. Critical, especially feminist, scholarship mostly regards the femme fatale as a sexist construction of a male fantasy and treats her as an expression of misogyny that ultimately serves to reaffirm male authority. But this thesis proposes alternative ways of viewing the femme fatale by showing how she can also serve as a figure for imagining female agency. As such, I focus on a particular character type that is distinct from the general archetype of the femme fatale because of the greater degree of agency she demonstrates. This 'criminal femme fatale' uses her sexual appeal and irresistible wiles both to manipulate men and to commit criminal acts, usually murder, in order to advance her goals with deliberate intent and full culpability. This thesis reveals and explains the agency of the criminal femme fatales in American Hardboiled crime fiction between the late 1920s and the end of World War II in the works of three authors: Dashiell Hammett, Raymond Chandler and James M. Cain. The criminal femme fatales in the narratives of these authors show a subversive power and an ability to act - even though, or perhaps only if, this action is a criminal one. I show that these criminal femme fatales exhibit agency through their efforts to challenge not only the 'masculine' genre and the criminal space that this genre represents, but also to undercut the male protagonist's role and prove his failure in asserting control and dominance. Hammett's narratives provide good examples of how the criminal femme fatales function on a par with male gangsters in an underworld of crime and corruption. Chandler's work demonstrates a different case of absent/present criminal women who are set against the detective and ultimately question his power and mastery. Cain's narratives show the agency of the criminal femme fatales in the convergence between their ambition for social mobility and their sexual power over the male characters. To explain how these female characters exhibit agency, I situate this body of literature alongside contemporaneous legal and medical discourses on female criminality. I argue that the literary female criminal is a fundamentally different portrayal because she breaks the 'mad-bad' woman dichotomy that dominates both legal and medical discourses on female criminality. I show that the criminal femme fatales' negotiations of female agency within hardboiled crime fiction fluctuate and shift between the two poles of the criminalized and the medicalized women. These criminal femme fatales exhibit culpability in their actions that bring them into an encounter with the criminal justice system and resist being pathologized as women who suffer from a psychological ailment that affect their control. The thesis concludes that the ways in which the criminal femme fatales trouble normative socio-cultural conceptions relating to docile femininity and passive sexuality, not only destabilize the totality and fixity of the stereotype of the femme fatale in hardboiled crime fiction, but also open up broader debates about the representation of women in popular culture and the intersections between genre and gender.

Full textAbstract:
Foucault's argument in the short work "Of Other Spaces" suggests that rhetoric can be defined as how language is used to create and foster power inequities in hierarchical systems. Further, rhetoric enables individuals or groups to gain credibility and mobility within those systems--and to deny that same credibility and mobility to others. The nineteenth and early twentieth century was a period of transition for women, particularly middle- and upper-class white women. During this time, activist activities conducted by and on behalf of women were considered a threat to U.S. society. As a result, rhetoric was used with the intention of limiting American women's credibility and mobility.Although women had always been considered physiologically and intellectually inferior, diagnoses with a variety of "female-only" ailments became more common in the late nineteenth and early twentieth centuries. For men threatened by women's increasing political activism, this became a very effective method of arguing that women should be denied access to power. Because women were considered outside of the structure of society by virtue of a physiological state they were unable to change, then by definition women could only be regulated, and never regulate. Moreover, the postbellum expansion of civil society into a mass-market structure was an extremely efficient means of distributing that message.In this work, I use Foucault's "science of discipline" as the heuristic to analyze these debates. Foucault lists numerous categories and subcategories that can fall under the science of discipline--far too many to productively and coherently apply here. Therefore, I have modified the science of discipline into a four-pronged process. Applying this heuristic to the definition of rhetoric put forth here, I argue in this work that the medical profession, the magazine industry, and activist women engaged in dialogue with one another within the context of the suffrage movement. I argue that these specialized discourses responded to and built upon ideological allegiances, both explicitly and implicitly, to address the issue of woman's place in society--the "woman question."

A print copy of this title is available from the UO Libraries, under the call number: MUSIC ML82 .W35 2008Using muted group theory, this thesis explores the experiences of an all-woman rock band in the current cultural climate. This qualitative study uses a methodological triangulation that incorporates ethnography, in-depth interviews, and feminist critical discourse analysis. The data reveal that women in the rock music scene are a muted group, and as such they face many unique challenges, especially when attempting to create music using a feminist collaborative creative process, or conveying a message that challenges patriarchal gender norms. The results of this study point to numerous opportunities for researchers, educators, and those involved in the music scene to examine issues surrounding gender in rock music.

Full textAbstract:
Este trabajo es un acercamiento a la narrativa testimonial desde dos perspectivas: por un lado, la revisión teórica de su naturaleza canónica o antropológica, y, por otro, el análisis de un texto ficcional que hace suyas numerosas características discursivas del testimonio, razón por la cual estuvo, tras su aparición, en una situación liminal entre lo etnográfico y lo literario.
Es así, pues, que Canto de sirena (1977) de Gregorio Martínez motivó una discusión sobre la naturaleza de un libro que, para algunos lectores o críticos, seguía la línea de diversos textos publicados en años anteriores, denominados bajo el rótulo general de testimonios y estrechamente ligados al trabajo antropológico y sociológico, los cuales tenían la intención de dar a conocer y denunciar, desde la voz de los afectados, diversas situaciones de opresión, abusos o subyugación. El libro de Martínez fue acogido y leído bajo esta perspectiva, aun cuando, desde el formato, daba claras muestras de que estaba enmarcado en el campo literario. A partir de la dialéctica con estudios teóricos sobre el testimonio y una lectura analítica de la novela, se evidenciará el uso del modo testimonial como un recurso discursivo empleado por el autor para dotar de un carácter social y colectivo a su texto.
Con cuestiones tales como analizar y desentrañar quién habla en el testimonio, a quién se dirige el testimoniante o a quiénes representa, así como qué es lo que se cuenta en estos relatos colectivos, se abordará el problema que tratará de responder a la pregunta: ¿Cómo se ficcionalizan los recursos retóricos y enunciativos del testimonio canónico en la novela Canto de sirena?.Tesis

A família Trichechidae pertence à ordem Sirenia, mamíferos aquáticos preferencialmente herbívoros que habitam regiões costeiras. Atualmente, esta família inclui as três espécies viventes de peixes-bois: Trichechus manatus, encontrado na costa atlântica das Américas, ocorrendo descontinuamente desde a Flórida (Estados Unidos) até o Brasil (estado de Alagoas); Trichechus inunguis, endêmico da bacia amazônica; e Trichechus senegalensis, distribuído na costa atlântica da África, do Senegal a Angola. Adicionalmente, são descritas duas subespécies de T. manatus, T. m. latirostris (peixe-boi da Flórida), que ocorre na Flórida e Golfo do México, e T. m. manatus (peixe-boi das Antilhas), encontrado no México, Caribe e Américas Central e do Sul, até o nordeste do Brasil. Esta designação subespecífica difere quanto aos dados cranianos e moleculares. Neste estudo foram usadas abordagens morfométricas geométricas e citogenéticas para avaliar a existência de variação geográfica em T. inunguis, T. m. manatus, T. m. latirostris e T. senegalensis, com o propósito de analisar variações morfológicas do crânio intra e interespecíficas, e diferenças cariotípicas em T. m. manatus e T. inunguis do Brasil. Os resultados das análises de morfometria geométrica revelaram nenhum dimorfismo sexual de tamanho e forma do crânio em nenhuma das espécies e a separação da população de T. inunguis das populações de T. senegalensis, T. m. manatus e T. m. latirostris por mudanças de forma do crânio, havendo sobreposição entre alguns destes indivíduos. T. m. manatus e T. m. latirostris apresentaram maior tamanho de crânio que T. inunguis e presença de alometria (forma relacionada com tamanho) foi observada. As análises intraespecíficas de forma do crânio mostraram a separação da população brasileira de T. m. manatus das populações do Caribe de T. m. manatus e dos Estados Unidos de T. m. latirostris, as quais sobrepuseram-se parcialmente, enquanto que em T. inunguis não houve uma clara separação entre suas populações geográficas. Também não foi observada variação de tamanho do crânio entre as populações de nenhuma das espécies. O pequeno tamanho amostral não permitiu que uma análise intraespecífica fosse realizada em T. senegalensis. Considerando que somente indivíduos do nordeste do Brasil foram amostrados e que os espécimes do Suriname e Guiana apresentaram forma do crânio mais similar àquela da população do Caribe, é sugerido a hipótese de que a foz do rio Amazonas pode ter interrompido ou estar interrompendo o fluxo gênico nas populações de T. m. manatus do Brasil, condizente com modelos de especiação alopátrica. Além disso, a população do peixe-boi antilhano do Brasil mostrou-se tão diferenciada, em relação à forma do crânio, quanto são as duas espécies bem reconhecidas de peixes-bois (T. inunguis e T. senegalensis). Os resultados das análises cromossômicas também revelaram diferenças cariotípicas estruturais entre T. m. manatus (2n = 48) do Brasil e as populações do peixe-boi antilhano de Porto Rico e do peixe-boi da Flórida, reforçando as conclusões obtidas pela morfometria geométrica e sugerindo o isolamento reprodutivo da população do Brasil. A análise citogenética da população brasileira de T. inunguis (2n = 56) revelou a presença de um par cromossômico heteromórfico e polimórfico com relação à morfologia acrocêntrica e submetacêntrica, mostrando um padrão que pode ser indicativo de evolução cromossômica recente, devido à existência de variantes cariotípicas heterozigotas. Em adição, não foi verificada a presença de sítios teloméricos intersticiais nos cromossomos de T. inunguis e T. m. manatus pela técnica de hibridização in situ fluorescente. Os resultados obtidos neste estudo para a população brasileira de T. m. manatus suportam a evidência preliminar dos dados de DNA mitocondrial e estas conclusões combinadas não coincidem com a designação subespecífica de T. manatus atualmente aceita, baseada em medidas lineares do crânio.

Full textAbstract:
In a discipline commonly faulted for ad hoc assumptions and models with very little discriminating observational evidence, cosmologists are continually trying, and in many cases succeeding, to improve both the data and models. However, the desire to support currently favoured models often dominates research and may lead to a systematic bias being introduced in favour of a model before a strong body of supporting evidence has been accumulated. This is perhaps most evident in literature supporting the viability of Gamma Ray Bursts as cosmological distance indicators, where aside from subjective data-selection, the basic statistical methods are at best questionable and at worst incorrect. To this end, we construct a simple cosmology-independent illustration of the effect that the application of these methods has on parameter estimation and discuss the correct method to apply to current data. We also investigate the constraints potential future Gamma Ray Burst data may place on alternatives to the status quo Concordance Model in the shape of Conformal Gravity and Unified Dark Matter through a widely applicable and transferable Bayesian model comparison technique and the development of a representative mock data set. Finally, we investigate gravitational wave standard sirens as an alternative high-redshift distance indicator. We first illustrate their strong diagnostic potential through a Bayesian model comparison between the standard Unified Dark Matter model and a variant in which the dark component is redshift dependent. By drawing mock data from a known cosmological model, thus fixing the expected values of the model parameters, we find that while 182 Type 1a Supernovae are readily confused between constant and evolving models, just 2 standard sirens are able to successfully identify the correct model. Having established standard sirens as an effective tool in cosmological model comparison, we then address the potential confusion of models with dynamical dark energy and intrinsic curvature. We show that currently used distance indicators - Type 1a Supernovae, Baryon Acoustic Oscillations and the Cosmic Microwave Background Radiation - are not reliable enough to identify a small amount of intrinsic curvature, which partly justifies the common practice of assuming flat space in order to reduce the number of free parameters. However, we show that the addition of even a small number of standard sirens greatly reduces this problem. The addition of just two sirens offers a slight improvement, while adding ten sirens to the aforementioned list of indicators halves the range over which there is uncertainty between models.

If you are the author or principal advisor of this work and would like to request open access for it, please contact us at open-help@bu.edu. Thank you.The use of emergency lights and sirens as warning devices by ambulances is a hotly debated topic within the Emergency Medical Services. For the last few decades, research has shown that lights and sirens have only a minimal effect on time required to transport patients to the hospital, and essentially no positive effect on patient outcome. Meanwhile, thousands of ambulance crashes occur every year (usually during the operation of lights and sirens), and its possible that's tens of thousands of crashes are occurring as a result of a passing ambulance, though not directly involving the ambulance itself. This paper is meant to provide a thorough review of the science behind the use of lights and sirens, the risks they pose to EMS providers, patients, and the public, and strategies to help curb the cost they pose both in dollars and lives. The available literature on this subject all points to the use of lights and sirens being out dated, ineffective, and dangerous, and yet almost nothing has been done to solve the problems they cause. Continued research and development is needed to help make ambulances safer for their occupants, more effective driver training programs need to be offered to EMS providers, and protocols need to be adopted to limit the unnecessary use of L&S.

There are evidences that Amazonian manatee convey identity information, to its conspecifics, using sounds. Evidences about the presence of vocal signature and individual recognition have been documented in the specie. However, there is little information about the vocal behavior and the development of the individual vocal pattern for this species. The vocalizations of thirty eight individuals living in captivity at INPA had their vocalizations recorded throughout eleven years. The calling rates from these animals were compared across age classes and sexes. Three females that reproduced in captivity also had their calling rates compared in two different stages: lactating and non-lactating. Lactating females and calves presented higher calling rates than the others, emphasizing that the main role of manatee s acoustic communication is the mainentance of proximity between mother and calf. Aiming to verify if the variability within individual vocal pattern would tend to decrease with age, we analyzed vocalizations of twenty three individuals. We performed spectrographic cross-correlation of vocalizations emitted by each animal, within each recording day. The resulting similarity indexes were plotted across time for each individual. The similarity indexes did not show any clear tendency of increase or decrease across time. We also investigated intra-individual variations in some acoustic parameters. Among them, only the maximum fundamental frequency showed significant increase in five individuals that were analyzed during the change of age class from calf to juvenile. When we compared the acoustic parameters within age classes and sexes, we did not find any significant differences in the fundamental range or in the maximum fundamental frequency. Only signal duration showed a significant difference among age classes, more specifically, between calves and adults, with longer signal durations in adults. There wasn t a significant difference in signal duration between calves and juveniles, or between juveniles and adults. A calf born in captivity was recorded since birth. In this case study, we observed that the similarity between the calf s vocalizations and those from his mother increased through time, suggesting the existence of vocal learning in this species.
Existem evidências de que o peixe-boi da Amazônia (Trichechus inunguis) fornece a seus co-específicos informações acerca de sua identidade por meio da comunicação sonora. Evidências da existência de assinatura vocal, bem como de reconhecimento individual já foram documentados na espécie. No entanto, existem poucas informações sobre o comportamento vocal da espécie e sobre o desenvolvimento do seu padrão vocal individual. Trinta e oito indivíduos vivendo em cativeiro no INPA tiveram suas vocalizações gravadas em um período de onze anos. As taxas de vocalização desses animais foram analisadas e comparadas entre classes etárias e sexos. Três fêmeas que se reproduziram em cativeiro também tiveram suas vocalizações comparadas em duas fases distintas: lactação e não-lactação. Fêmeas em lactação e filhotes apresentam as taxas de vocalização mais elevadas que os demais, sugerindo que a coesão entre mãe e filhote seria a principal função da comunicação sonora no peixe-boi da Amazônia. Para verificar se o padrão vocal individual tenderia a reduzir sua variabilidade ao longo do tempo, vinte e três indivíduos tiveram suas vocalizações analisadas. Para isso, os espectrogramas das vocalizações emitidas, por indivíduo, a cada dia de gravação foram submetidos a uma correlação cruzada. Os índices de similaridade resultantes dessa correlação foram plotados, em relação ao tempo, para cada indivíduo. Não houve tendência clara ao aumento ou à redução dos índices de similaridade com o passar do tempo. Variações intra-individuais também foram analisadas em alguns parâmetros acústicos. Dentre eles, apenas a freqüência de maior intensidade na fundamental variou significativamente, aumentando seu valor para os cinco indivíduos acompanhados na mudança de classe etária (de filhotes para juvenis). Quando parâmetros acústicos foram comparados entre as classes etárias e entre os sexos, diferenças significativas não foram encontradas entre a variação da freqüência fundamental, nem na freqüência fundamental de maior intensidade. Somente a duração do sinal mostrou variação significativa entre classes etárias, mais especificamente entre filhotes e adultos, sendo mais elevada nestes últimos. Não houve diferença significativa na duração do sinal entre filhotes e juvenis nem entre juvenis e adultos. Um filhote nascido em cativeiro teve suas vocalizações gravadas a partir do nascimento. Em um estudo de caso, observou-se o aumento da similaridade entre as vocalizações do filhote e as vocalizações maternas ao longo do tempo, sugerindo aprendizado vocal na espécie.

Full textAbstract:
The purpose of this thesis was to critically investigate the noise produced by the sirens fitted to South Australian Police general patrol vehicles and calculate if this noise was of an intensity to cause noise induced hearing loss. Previous studies in Western Australia and in South Australia examined noise emissions from emergency vehicle sirens for the purpose of selecting the most suitable siren for emergency vehicles, this being the siren emitting the greatest intensity of sound. This study has researched emergency vehicle sirens from the perspective of employee exposure to siren noise. Noise levels were recorded from inside the police vehicles using a hand held digital sound level meter while the vehicle was driven under driving conditions of stationary, 60 km/h, 80 km/h and 100 km/h. Noise level readings were taken with the front windows closed and open . South Australian police sirens have three distinct settings with differing noise outputs. The change in vehicle speed was found to affect the noise intensity within the vehicle for all 3 siren types. The peak noise level recorded was with the windows open and the vehicle travelling at 100 km/h ( 95, 94 and 97 dB(A) for the three sirens respectively). Closing of the front windows when stationary and when driving at was found to reduce the noise intensity within the vehicle. The greatest reduction from closing the windows was recorded at 100 km/h. This reduction was 11, 9 and 7 dB(A) respectively for the three siren types. Siren type one was the siren normally used by the South Australian police, consequently the majority of exposure by South Australian police employees is to siren type one. These sirens produced a peak internal vehicle noise Intensity of 95 dB(A) at 100 km/h with the windows open and 84 dB(A) at 100 Km/h with the windows closed . The reading of 95 dB(A) is greater that the 90 dB(A) eight hour continuous exposure limit set by the South Australian Occupational Health Safety and Welfare Act of 1986. The maximum exposure time for unprotected ears using the 90 dB(A) eight hour equivalent continuous A weighted sound pressure level (Laeq,8h) would be 2 hours and 30 minutes (150 minutes) . The assumption of this study was that noise intensity levels in excess of 90 dB(A) Laeq,8h will cause noise induced hearing loss. Therefore the noise intensity recorded from the vehicle siren tests at 100 km/h with the windows open have the potential to cause hearing loss if the duration exceeds 150 minutes. The review of existing records of vehicle pursuits showed that between January 1 1998 and December 31 2001, there were three instances where the exposure to siren noise exceeded the 150 minute exposure period. This study found the closing of the windows to reduce the noise intensity at all speeds and all sirens types to below the 90 dB(A) Laeq,8h. It is therefore recommended that all police vehicles whilst using the sirens close all windows to reduce the noise intensity within the vehicle.

Full textAbstract:
A functional and effective alarm signal is a critical component of alarm systems designed to alert workers of impending danger. In a previous study (Hansson, 2017) background alarm sirens composed of changing-state sounds with an embedded temporal deviant, produced greater disruption of serial short-term memory than a signal without a deviant. However, to give rise to disruption the siren needed to change from fast to slow, since a change from slow to fast was impotent in its effect on task performance. In the current study, whether acoustic change was a necessary prerequisite for obtaining the fast-to-slow deviant effect was explored. Thus, repeated tones—steady-state sequences—presented at slow or fast rates were used with or without a temporal deviant (change from slow-to-fast vs. change from fast-to-slow). In the context of the steady-state sequences, both slow-to-fast and fast-to-slow temporal deviants produced disruption relative to the fast and slow control sequences. This suggests that a changing-state sequence is required for the fast-to-slow temporal deviant effect to arise. However, an alternative explanation based upon inter-stimulus intervals is also entertained. Understanding the acoustic parameters of sound is necessary to develop alarms sirens that are better at capturing attention. The current study suggests that embedding temporal deviants within sirens can promote greater attentional capture, but that this may depend on the nature of the alarm signal (whether it is changing vs. steady-state) and the direction of the change of speed (slow-to-fast vs. fast-to-slow).

Full textAbstract:
Alarm signals such as sirens are crucial in alerting users of impending dangers. Therefore, it is important that the siren is designed so it can capture user's attention. In a previous study (Hansson, 2017) background alarm sirens composed of changing-state sounds with an embedded temporal deviant, produced greater disruption of serial short-term memory than a signal without a temporal deviant. However, to give rise to disruption the siren needed to change from fast to slow, since a change from slow to fast was impotent in its effect on task performance. This was further addressed in Hansson (2018) where it was shown that acoustic change appeared to be a necessary prerequisite for obtaining the fast-to-slow temporal deviant effect: When steady-state sounds were used fast-to-slow and or slow-to-fast temporal deviants were equally disruptive of serial recall. However, in order to create a steady-state siren, inter-stimulus intervals were incorporated into the siren to prevent the continuous uninterrupted presentation of a single tone. Since inter-stimulus intervals were not used in Hansson (2017) it could be the presence of these that eliminated the potency of the fast-to-slow over the slow-to-fast temporal deviation effect in Hansson (2018). Therefore, the current study was undertaken to investigate whether the embedding inter-stimulus intervals within a changing-state siren would restore the potency of the fast-to-slow temporal deviation over the slow-to-fast temporal deviation in capturing attention. The additional disruption for fast-to-slow temporal deviants over slow-to-fast temporal deviants (that did not produce disruption relative to control) returned in the current study when inter-stimulus intervals were included within the siren. The results support the notion that the additional disruption produced by fast-to-slow, over slow-to-fast temporal deviants depend on the changing-state properties of the siren. Implications of this result for the design and operation of sirens within ecologically valid settings are discussed.

Dissertation (PhD)--University of Stellenbosch, 2006.ENGLISH ABSTRACT: Increases in taxonomic sampling and the numbers and types of markers used in phylogenetic studies have resulted in a marked improvement in the interpretation of systematic relationships within Eutheria. However, relationships within several clades, including Paenungulata (Hyracoidea, Sirenia, Proboscidea), remain unresolved. Here the combination of i) a rapid radiation and ii) a deep divergence have resulted in limited phylogenetic signal available for analysis. Specifically i) a short internode separating successive branching events reduces the time available for changes to occur, while ii) the longer the time since divergence, the greater the opportunity for signal to be negatively affected by homoplasy. This is evident in both molecular and morphological data where an overall consensus on paenungulate relationships is lacking. Morphological analysis of anatomical and fossil evidence favours the association of Sirenia (S) and Proboscidea (P) (Tethytheria) to the exclusion of Hyracoidea (H); further, support for uniting these three taxa as Paenungulata is contentious. In contrast, molecular data provide strong support for Paenungulata but intra-ordinal relationships are ambiguous. Although results from mitochondrial DNA sequence data favour Tethytheria, there is no consensus of support for this clade from nuclear DNA. Nuclear DNA is typified by node instability but favours H+P in the largest concatenation of sequences. Due to the expected increased effect from homoplasy and consequently the increased likelihood for misleading signal, it is unclear which result is most likely to represent the “true” tree. An analysis of available and added intron sequences to characterise signal heterogeneity among nuclear DNA and mitochondrial DNA partitions indicated that the phylogenetic utility of partitions varies considerably. Subpartitioning of the data according to similar evolutionary processes/characteristics (e. g., mtDNA vs. nDNA and codon position) revealed new insights into the signal structure of the data set; specifically i) that nuclear DNA first codon positions, and to a lesser degree second codon sites, provide convincing support for H+P, and ii) that support for S+P by faster evolving sites within mtDNA suggests that this may be the result of misleading signal. If H+P represents the “true tree”, then support for this clade indicates that phylogenetic signal has been reduced over time as a result of multiple hits, which explains the presence of (hidden) support in slower evolving sites where homoplasy is less likely to occur, in contrast to faster evolving sites where no support for H+P was observed. In an attempt to provide further resolution from an alternative perspective to that possible with DNA sequence data, chromosomal rearrangements were identified among the three paenungulate lineages. Using comparative chromosome painting, unique changes within each order and specific to Paenungulata were characterised, however, intra-ordinal synapomorphies were not recovered. Although this may suggest a hard polytomy, the slow to moderate rate of evolution estimated from the data is likely not sufficient relative to the rapid radiation associated with the paenungulate node. Further examination of chromosomal rearrangements at a higher level of resolution may yet reveal informative changes.

By laasgenoemde het die kombinasie van i) ‘n vinnige radiasie en ii) ‘n diep divergensie die filogenetiese sein wat vir analise beskikbaar is, beperk. Meer spesifiek sal i) opeenvolgende vertakkings wat deur kort internodusse geskei word die beskikbare tyd waartydens veranderings kan intree, verminder, terwyl ii) ‘n toename in tydsverloop sedert divergensie die kans dat die sein deur homoplasie nadelig beïnvloed sal word, vergroot. Dit word in sowel molekulêre en morfologiese data, waar ‘n oorhoofse konsensus t.o.v. verwantskappe van Paenungulata ontbreek, waargeneem. Morfologiese analise van anatomiese en fossielbewyse ondersteun die samevoeging van Sirenia (S) en Proboscidea (P) (Tethytheria) ten koste van Hyracoidea (H). Ondersteuning vir die samevoeging van dié drie taksa as Paenungulata is egter aanvegbaar. In teenstelling hiermee word Paenungulata sterk deur molekulêre data ondersteun, al bly die verwantstkappe op intra-orde vlak, steeds onduidelik. Alhoewel die resultate van mitochondriale DNA op Tethytheria dui, word die klade nie deur data van kern-DNA ondersteun nie. Kern-DNA word gekarakteriseer deur node instabiliteit maar verkies H+P in die grootste samevoeging van geen volgordes. Na aanleiding van die verwagte toename in die effek van homoplasie en die gevolglik groter kans op ‘n misleidende sein, is dit nie duidelik watter van die resultate die meer korrekte filogenetiese stamboom verteenwoordig nie. Analise van beskikbare en nuut toegevoegde intron-volgordes om sein-heterogeniteit tussen kern- en mitochondriale DNA verdelings te karakteriseer, toon dat die filogenetiese nut van verdelings beduidend verskil. Onderverdeling van die data op grond van soortgelyke evolusionêre prosesse/karaktereienskappe (bv. mtDNA vs. nDNA, en kodonposisie) het na nuwe insigte in die seinstruktuur van die datastel gelei. Meer spesifiek dat i) kern-DNA se eerste kodonposisies, en tot ‘n mindere mate die tweede kodonposisies, H+P oortuigend ondersteun en ii) dat ondersteuning vir S+P deur posisies binne mtDNA wat vinnig verander, op ‘n misleidende sein mag dui. As H+P die korrekte stamboom verteenwoordig dui ondersteuning vir die klade op ‘n filogenetiese sein wat met verloop van tyd as gevolg van veelvuldige seinvoorkomste verklein het. Dit verklaar die aanwesigheid van versluierde ondersteuning in stadig-veranderende posisies waar die neiging tot homoplasie klein is, in teenstelling met posisies wat vinniger verander en waar ondersteuning vir H+P nie waargeneem is nie. Op soek na verhoogde resolusie vanuit ‘n ander perspektief as DNA-volgordebepaling, is chromosomale herrangskikkings in die drie stamlyne van Paenungulata nagevors. Met behulp van vergelykende chromosoomkleuring is unieke veranderings binne elke orde en spesifiek binne Paenungulata gekarakteriseer, maar geen sinapomorfe kenmerke is op die intra-orde vlak gevind nie. Alhoewel dit op ‘n onopgeloste politomie mag dui, is die stadige tot matige evolusietempo wat van die data afgelei word, relatief tot die vinnige radiasie wat met die Paenungulata-nodus geassosieer word, waarskynlik onvoldoende vir ‘n oplossing. Verdere navorsing oor chromosomale herrangskikkings met ‘n hoër resolusievlak mag addisionele insiggewende veranderings aantoon.

Full textAbstract:
An effective alarm system is a critical part of many different types of jobs. It is also important that the alarm signal can capture human attention and convey appropriate urgency. In the current study the effect of siren sounds with or without unexpected, deviant sounds represented by a change of speed (a temporal deviant) were tested to evaluate if such change could successfully capture attention. The results showed that distraction was more pronounced when the deviant within the sound was a change from fast to slow as compared with slow to fast. Therefore, an alarm signal using a temporal deviant – changing from fast to slow—can be effective in capturing human attention and might be factored into the design of alarm systems.

Full textAbstract:
Population structure can be defined as a difference in the frequencies of alleles among populations, and it is often caused by barriers to dispersal. I used mitochondrial DNA sequences to examine the population structure of two large, aquatic salamanders, Amphiuma means (the Two-Toed Amphiuma) and Siren lacertina (the Greater Siren), at two spatial scales in peninsular Florida. Both species appear to have similar life histories, including poor dry land dispersal capabilities, and I hypothesized that they would exhibit significant population structure at both broad and fine scales. Wetland loss and landscape fragmentation are certain to have caused decreases in abundance and even extirpation of local populations of both species. Understanding current levels of genetic diversity is important in conservation efforts, particularly if individuals must be translocated in the future.
A portion of the cytochrome b gene was analyzed for 34 Amphiuma means and 21 Siren lacertina sequences. A neighbor-joining tree and haplotype network showed that A. means exhibited statistically significant population structure at the broad, but not the fine scale. The lack of structure at the fine scale was attributed to periodic flooding among drainage basins in the low-lying study area. The same analyses showed that S. lacertina did not exhibit statistically significant population structure at the broad scale (analyses were not conducted at the fine scale because of low sample size). The difference in broad-scale population structure between the two species is the result of a difference in gene flow, which in turn, can be the result of a difference in effective population size (Ne), female dispersal capability and/or behavior, chance of bait-bucket transfer, or biogeographic history. The best of these possible explanations seems to be a difference in biogeographic history. For the two sites from which both species were sampled, estimated population divergence date was 3.3-6.4 million years ago (mya) for A. means and 0.04-0.5 mya for S. lacertina. The large difference in estimated divergence dates suggests that S. lacertina colonized peninsular Florida from somewhere else following a glacial sea level rise or an interglacial sea level fall, at a time when A. means was already present in refugia within peninsular Florida. This is the first study to explicitly examine the population genetics of A. means and S. lacertina, and future studies should examine their population genetics range wide, to elucidate how gene flow and/or historical biogeography may have contributed to population structure elsewhere.

Full textAbstract:
The salamander family Sirenidae is composed of two extant genera, Siren and Pseudobranchus, each with two known species. Several questions regarding Sirenidae life history persist, and much of the available life history data for Pseudobranchus are attributed to studies of P. axanthus in northern Florida. Information on the reproductive biology of P. axanthus is limited, and historical references often suggest contradictory results. This study was undertaken to clarify information and expand on the limited data regarding P. axanthus reproductive biology, specifically for southern Florida populations. The study population was most likely the P. a. belli subspecies. P. axanthus in southern Florida exhibited year round, continuous reproduction with oviposition documented in nine months. Potential clutch size was positively correlated to female size. The largest observed potential clutch was a female with 58 pre-ovulatory oocytes. The largest observed bout was a female with 15 oviductal eggs. Female P. axanthus in southern Florida oviposited eggs singly and at total densities of 3-4 eggs/m2. Developmental time to egg hatching lasted about 30 days, larvae hatched at 16mm TL, and minimum size at female sexual maturity was 115mm TL and 72mm SVL. The reproductive biology of P. axanthus was distinctly contrasting to other members of the family Sirenidae, S. intermedia and S. lacertina, that occupy the same habitat at the same study location.

Full textAbstract:
Les premiers representants des andlau apparaissent dans la deuxieme moitie du xiie siecle. Ce sont des ministeriaux de l'abbaye d'andlau. Ce lignage, dont le nom se fixe a la fin du xiie siecle s'emancipe au cours du siecle suivant pour former, avec d'autres familles de chevaliers, la basse noblesse. Grace a l'appui de leurs chateaux, ils accroissent leur influence dans diverses regions d'alsace, et notamment autour d'andlau. A partir du xve siecle, ils se developpent particulierement en haute alsace par le biais, entre autres, de mariages. Sans reussir a se creer un territoire, les andlau se constituent une importante seigneurie sur l'ensemble de l'alsace. Le noyau primitif que constitue la region d'andlau - auquel tous les andlau restent attaches- est partage entre les differentes branches du lignage alors que les biens acquis par mariage sont herites par la descendance directe. Cette politique de partage et de transmission des possessions leur a permis de joir de revenus confortable et de ne pas tomber dans l'insignifiance. Leur fortune et les contacts qu'ils entretiennent au sein de la societe leur ont permis d'occuper des fonctions publiques prestigieuses: plusieurs andlau se sont illustres dans des carrieres politiques et ecclesiastiques. Les andlau comptent parmi les plus importantes familles de la noblesse alsacienneThe first membres of the andlau's lineage appears half the second part of 12th century. They are ministerials of the andlau's abbey. The lineage became in the 13th cebtury, with other knights families, part of nobility. Through their castels, they increase their authority accross alsace, espacially in andlau and its surroundings. From the 15th century, they particulary expand in south alsace. Though they did not manage to build a territory they set up a significant lordship all over alsace. Andlau and it's neighbourhood is beiing shared between the different branch of the family while the goods acquired by the mariage are to be inherited by the direct descendants. This sharing and inheriting policy allowed the andlau's lineage not to sink into poverty and to be well off. Their fortune and the relations they up in the society made them able to have prestigious activities in the public relations : some of them become famous in political or clerical careers. The andlau's family is one oneof the most important alsacian noble dynasty of the middle ages
