Trying To understand all-equity firms

This paper studies all equity firms and shows which are in US firms, the main drivers of zero-debt policy. I analyze 6763 U.S. listed companies in years 1987-2009, a total of 77442 firms year. I find that financial constrained firms show a higher probability to become unlevered. In the opposite side, firms producing high cash flow are also likely to become unlevered, paying their debt. Some firms create economies of scale in the use of funds, increasing the probability of become unlevered. The industry characteristics are also important to explain the zero-debt policy. However is the high perception of risk, the most important factor influencing this extreme behavior, which is consistent with trade-off theory.

Nuevas formas de enseñanza en mimo corporal dramático: la técnica corporal y la experiencia somática más allá de la forma y la estética generadas

Planteamos el estudio y la sistematización del mimo corporal dramático, a partir de la experiencia en la práctica de dicha técnica y su enseñanza . Mas allá de inventar una nueva técnica o realizar un trabajo teórico sobre conceptos, intentaremos en base al trabajo práctico realizado en el ultimo año, a partir de las experiencias desarrolladas en las aulas de movimento del maestrado, referenciar sistematizar y poner por escrito los principios y bases del mimo corporal dramático, revisados desde nuevos planteamientos, mas allá de la estética que generó Decroux. Trabajamos en la recopilación y estudio de todos estos principios, desde la experiencia de los últimos cinco años dando clases de mimo corporal dramático en la Real Escuela Superior de Arte Dramático de Madrid y mas concretamente en el trabajo realizado en el ultimo año con un grupo de alumnos y ex-alumnos voluntarios con los que hemos estado investigando sobre la técnica del mimo corporal. No intentamos pues realizar un estudio teórico, basado en ideas, pensamientos, etc. sino exponer desde la experiencia real, desde ejercicios, improvisaciones, diálogos sobre la técnica en la práctica y desarrollo del movimiento. Recogemos aquí no los ejercicios trabajados o soluciones practicas, sino las conclusiones y las bases teóricas que las sustentan y sobre las que creemos que pueden arrojar luz sobre el conocimiento de esta técnica y facilitar tanto su comprensión como su practica, mas allá de la figura de Decroux o de un estilo concreto de movimiento.

Representations of gender in the writings of St. Francis Xavier: an interdisciplinary approach

Francis Xavier’s Letters and Writings are eloquent narratives of a journey that absorbed the Saint’s entire life. His experiences and idiosyncrasies, values and categorizations are presented in a clear literate discourse. The missionary is rarely neutral in his opinions as he sustains his unmistakable and omnipresent objective: the conversion of peoples and the expansion of the Society of Jesus. Parallel with this objective, the reader is introduced to the individuals that Xavier meets or that he summons in his epistolary discourse. Letters and Writings presents us with a structured narrative peopled by all those who are subject to and objects of Xavier’s apostolic mission, by helpful and unhelpful persons of influence, and by leading and secondary actors. What is then the position of women, in the collective sense as well as in the individual sense, in the travels and goals that are the centre of Xavier’s Letters and Writings? What is the role of women, that secondary and suppressed term in the man/woman binomial, a dichotomy similar to the civilized/savage and European/native binomials that punctuate Xavier’s narratives and the historic context of his letters? Women are not absent from his writings, but it would be naïve to argue in favour of the author’s misogyny as much as of his “profound knowledge of the female heart”, to quote from Paulo Durão in "Women in the Letters of Saint Francis Xavier" (1952), the only paper on this subject published so far. We denote four great categories of women in the Letters and Writings: European Women, Converted Women, Women Who Profess another Religion, and Women as the Agents and Objects of Sin, the latter of which traverses the other three categories. They all depend on the context, circumstances and judgements of value that the author chooses to highlight and articulate.

All the world in a boat: portuguese folklore, common sense and ideology

This essay sees “through” an object produced by Portuguese folklore: the moliceiro boat of Ria de Aveiro, whose most original characteristic is the group of four different panels painted on each boat. These unique panels have echoed national mythologies and have undergone influence from institutional channels of instruction and propaganda for much of the twentieth century. We will analyse how this boat expresses the inventory of a community’s identity, imagination, and practices.

Clinical Education - a fundamental curricular unit for all health practitioners

Clinical education is recognized as being crucial for the training of health professionals. This subject is debated amongst teachers, students and professionals. Besides the clinical and research skills, we look for other competencies such as oratory, creative thinking or leadership. We present the results of a study with 4th graders. It’s a exploratory study; the main purpose was to evaluate the outcomes of a unit of clinical education prepared according a new set of competencies and methodologies. The competencies were seen as valuable. Organization, leading or supporting a colleague, rethinking a program to serve client and family are equally important.

Hay vida más allá del trabajo: la relación entre la recuperación de recursos y el desempeño en el trabajo

En los últimos años presenciamos profundas alteraciones en la relación trabajo/ tiempo libre. El proceso de globalización, las alteraciones económicas y sociales produjeron cambios en las estructuras sociales, en el trabajo y en la forma como los individuos ocupan su tiempo libre. Estas transformaciones tuvieron un impacto indeleble en la organización del trabajo, con consecuencias a nivel de las exigencias colocadas a los trabajadores; éstos se vieron obligados a adaptarse a medios cada vez más exigentes, estresantes y en constante mutación. Al mismo tiempo, muchos trabajadores vieron que aumentaba su jornada de trabajo y disminuían los períodos de descanso, dejando poco tiempo para la recuperación de las presiones a que estuvieron sujetos a lo largo de la jornada laboral.

Soft Janus, wrinkles and all

Right now you are probably sitting on a comfy cushion. This is most likely filled with polyurethane (PU) foam. PUs are very long molecules made up of many repeating units. If the repeating units are prepolymers – intermediate-mass building blocks – with more than two reactive end groups, a three-dimensional network will form – a rubber, or elastomer, which can behave elastically depending on the degree of network cross-linking.

A real-time quantitative assay for hepatitis B DNA virus (HBV) developed to detect all HBV genotypes

Hepatitis B virus (HBV) is a major cause of chronic liver disease worldwide. Besides genotype, quantitative analysis of HBV infection is extensively used for monitoring disease progression and treatment. Affordable viral load monitoring is desirable in resource-limited settings and it has been already shown to be useful in developing countries for other viruses such as Hepatitis C virus (HCV) and HIV. In this paper, we describe the validation of a real-time PCR assay for HBV DNA quantification with TaqMan chemistry and MGB probes. Primers and probes were designed using an alignment of sequences from all HBV genotypes in order to equally amplify all of them. The assay is internally controlled and was standardized with an international HBV panel. Its efficacy was evaluated comparing the results with two other methods: Versant HBV DNA Assay 3.0 (bDNA, Siemens, NY, USA) and another real-time PCR from a reference laboratory. Intra-assay and inter-assay reproducibilities were determined and the mean of CV values obtained were 0.12 and 0.09, respectively. The assay was validated with a broad dynamic range and is efficient for amplifying all HBV genotypes, providing a good option to quantify HBV DNA as a routine procedure, with a cheap and reliable protocol.
