Authors: Pérez Jorge Orlando , Bertoni Martín , Sattler Silvana Andrea , Terreno Dante Domingo 
Published: September 2015

Este trabajo se propone resolver el problema de la determinación de la estructura de financiamiento para cada pyme. En la mayoría de las investigaciones sobre este tema, se realizan análisis descriptivos acerca de las variables que inciden en la decisión sobre la mezcla entre pasivo y patrimonio en contextos diferentes, mientras que en este caso se aporta una herramienta, que se espera mejore el proceso de la toma de decisiones financieras. Para abordar el tema planteado, se propone un modelo matemático para que el administrador financiero de la pyme pueda establecer la mezcla de capitales más conveniente. Para ello, previamente, se identifican las características de las distintas fuentes de financiamiento, las variables que inciden en el riesgo y la asociación entre la fuente y el destino de los fondos. Se desarrolla la fundamentación matemática del modelo y luego se traslada el mismo a una planilla de cálculo electrónica, para que, al cargar los datos de las distintas variables, se pueda arribar a la mejor combinación entre fondos propios y ajenos, de manera que al confrontar con la rentabilidad de la inversión, se pueda obtener el mayor valor económico agregado.
Grado de conocimiento del adjetivo “intangibles”, y su relación con la identificación, reconocimiento, medición, valoración y revelación de “intangibles” en la información contable de las empresas en Popayán. Un análisis descriptivo y econométrico
Authors: Ramírez Gutiérrez Zoraida , Gómez Sánchez Andrés Mauricio 
Published: September 2015

Este artículo de reflexión pretende mostrar por medio de metodologías cualitativas (metodología Delphi y estudio de casos) y cuantitativas (econometría), el grado de conocimiento del término o adjetivo intangible y su asociación con la identificación, reconocimiento, medición y valoración, a efectos de la revelación de intangibles en la información contable y financiera de las organizaciones. Con la metodología Delphi se genera evidencia empírica con la ayuda de propietarios de empresas, procesadores y usuarios de información financiera, lo que mediante el estudio de casos se contrasta con las entrevistas y la información contable que ha sido revelada por empresas comerciales, industriales y de servicios de la ciudad de Popayán, Cauca. El trabajo de campo tiene como objetivo relacionar las variables grado de conocimiento del adjetivo intangible, con el grado de identificación y reconocimiento de intangibles en las empresas, para indagar sobre la importancia en la generación de valor de los mismos y, por tanto, la imperiosa necesidad de generar modelos que brinden posibilidades para la sistematización, medición y valoración de intangibles, como paso necesario e indispensable para la revelación y/o divulgación de los mismos en la información contable y financiera. </p>
El contrapunto de la percepción: Vallejo en clave local/global
Authors: Rueda María Helena 
Published: September 2015

La poca pacífica entrada al mercado global en la Colombia de los '80 y '90 ofrece un momento fecundo para la innovación literaria, según el estudio de María Helena Rueda "El contrapunto de la percepción: Vallejo en clave local/global". Para Rueda, el texto que lanza a Vallejo a la fama internacional, La virgen de los sicarios, constituye un holograma de un momento en el que intelectuales, artistas y líderes cívicos intentan representar realidades extremas para públicos internacionales. Nuevas subjetividades urbanas, como la del sicario, viven entre flujos mercantiles, en tanto una nueva literatura urbana colombiana se ubica en un espacio cultural que también siente el impacto de la globalización. Cuidadosamente, María Helena Rueda coloca La Virgen de los sicarios en este contexto, entre el canon nacional y un público internacional que acogió con entusiasmo "la sicaresca".
El malditismo de Fernando Vallejo como espectáculo melodramático
Authors: Hoyos Héctor 
Published: September 2015

El análisis de Héctor Hoyos se aproxima al arte de provocación de Vallejo como un espectáculo que subvierte la estructura afectiva del melodrama. En el presente artículo, Hoyos propone que tanto en La Virgen de los sicarios como en La puta de babilonia la voz de Vallejo, más allá de buscar simplemente escandalizar a su público, aprovecha sobre todo la oportunidad para insertarse en la coyuntura de la reproducción mediática, del espectáculo melodramático montado en torno a los íconos de Pablo Escobar y Juan Pablo II. El malditismo paródico de Vallejo es para Hoyos tardío y espectacular y está sostenido por el melodrama, un melodrama de fetichismos, reducciones y lugares comunes que -en medio de rancheras, tangos, villanos y brillantes corazones rojos- Vallejo busca trastornar desde adentro.
Fiel a su corriente: Las repeticiones de Vallejo en Casablanca la bella
Authors: Aristizábal Juanita C. 
Published: September 2015

En el presente artículo, Juanita Aristizábal ofrece un análisis de las diatribas recurrentes de Vallejo. A través de su estudio de longue durée, Aristizábal pone en contexto el tono que algunos críticos recientemente han comparado al de un “disco rayado”. Al contrario de la repetición superflua, esta cuidadosa examinación de la voz narrativa de Vallejo arguye que la repetición en sí es lo que le da la arquitectura resonante a la crítica social de Vallejo, concluyendo que el marco temático y espacial de sus libros evoluciona junto con el desarrollo de Colombia. Además de poner Casablanca la bella en el contexto de la obra más amplia de Vallejo, Aristizábal hace hincapié en las imágenes provocativas del dandy que Vallejo construye, ya no las del esteta que mira con nostalgia mientras París se derrumba sino las del autor que vive en las sombras de los rascacielos de Medellín.

Published: September 2015

Se muestran los resultados del estudio cinético de la degradación térmica del Poliácido Láctico – PLA, sin procesar y reprocesado por extrusión. Las muestras procesadas se obtenían después de cada reprocesamiento. Estas muestras se analizaron respecto a la temperatura de transición vítrea, índice de fluidez, poder calorífico y termogravimetría dinámica. Se determinó el triplete cinético por medio de los métodos Flynn-Wall-Ozawa (FWO), Friedman, Gyulai, Kissinger-Akahira-Sunose (KAS), Kissinger, Diferencial e Integral de Arrhenius, Briodo, Chang, Coats-Redfern, Flynn-Wall, Horowitz-Metzger, MacCallum-Tanner, Madhusudanan y el método Dinámico. Se encontró que la energía de activación () aumenta con el reprocesamiento y el factor de frecuencia () lo hace con la velocidad de calentamiento. También se encontró que el triplete cinético promedio, obtenido por métodos isoconversional y no isoconversional, toma valores para de 147.14 y 225.30 kJ/mol, de 26.94 y 45.07 min<sup>-1</sup> y de 0.86 y 0.91, respectivamente.
La violencia del narcotráfico en los países de mayor producción de coca: los casos de Perú y Colombia
Authors: Cubides Salazar Olga Marcela 
Published: September 2015

El presente trabajo realiza una comparación entre la violencia del narcotráfico de Perú y Colombia,siendo estos dos países los mayores productoresde cocaína en el mundo, pero teniendo niveles distintos de violencia. En el caso de Perú los niveles de violencia son bajos y en el caso de Colombia notablemente elevados. El trabajo plantea que el cultivo y producción de droga en sí mismo no es fuente de altos niveles de violencia,sino que la intensidad de esta depende de la presencia de más variables en juego.
<span>Notes on the development of </span><span class="hitHilite">Afronothrus</span> <span class="hitHilite">incisivus</span><span> (Acari: Oribatida) with new distribution records from Asia and Australia</span>
Authors: Wang Hui-Fu , Norton Roy A. , Lu Jian-Quan 
Published: September 2015

Afronothrus is a distinctive genus of oribatid mites in the family Trhypochthoniidae. The type species, A. incisivus Wallwork, was previously known from Africa, the neotropics, and various islands; our new records from China (Guangdong Province), Singapore and Australia (Queensland) show it to be circumglobal in warm latitudes. The ontogeny of this species is described and partially illustrated. Many aspects of development are intermediate in nature between those of other Trhypochthoniidae and the genus Trhypochthoniellus (Trhypochthoniellidae). All postlarval instars possess a sac-like cuticular structure invaginating from the bothridium, which was previously unknown.
Toward More Scalable Off-Line Simulations of MPI Applications
Authors: Casanova Henri , Gupta Anshul , Suter Frédéric 
Published: September 2015

The off-line (or post-mortem) analysis of execution event traces is a popular approach to understand the performance of HPC applications that use the message passing paradigm. Combining this analysis with simulation makes it possible to “replay” the application execution to explore “what if?” scenarios, e.g., assessing application performance in a range of (hypothetical) execution environments. However, such off-line analysis faces scalability issues for acquiring, storing, or replaying large event traces. We first present two previously proposed and complementary frameworks for off-line replaying of MPI application event traces, each with its own objectives and limitations. We then describe how these frameworks can be combined so as to capitalize on their respective strengths while alleviating several of their limitations. We claim that the combined framework affords levels of scalability that are beyond that achievable by either one of the two individual frameworks. We evaluate this framework to illustrate the benefits of the proposed combination for a more scalable off-line analysis of MPI applications.
Averted predator gaze reduces latency to flee by zebra-tailed lizards (Callisaurus draconoides)
Authors: Cooper William E. , Sherbrooke Wade C. 
Published: September 2015

Directness of a predator’s gaze affects several aspects of antipredatory behavior, including flight initiation distance (FID = predator-prey distance when fleeing begins), which is longer under direct than averted gaze. However, the effect of gaze directness on probability of fleeing or latency to flee (LF) in a short interval when a prey is immobile near an immobile predator is unknown. We predicted that probability of fleeing is greater and LF is shorter if the predator’s gaze is averted than direct. If the predator has not detected the prey, it will detect it immediately and attack when the prey moves while under direct gaze. Therefore, the prey is less likely to flee than if the predator is looking elsewhere. Under direct gaze the cost of fleeing decreases over time because the predator is increasingly likely to detect the prey. Under averted gaze, risk of being detected is constant for immobile prey and increases if the prey flees. Cost of fleeing under averted gaze is therefore constant and lower if the prey flees than under direct gaze at short latency, predicting shorter LF and greater likelihood of fleeing within a short fixed interval. We test this novel prediction of a model of the effect of gaze directness using the zebra-tailed lizard, Callisaurus draconoides. The proportion of lizards that fled was three times greater for averted than direct gaze, suggesting that prey under scrutiny reduce movement to avoid being detected. We discuss effects of gaze on FID, LF and probability of fleeing.
Quality improvement training for core medical and general practice trainees: a pilot study of project participation, completion and journal publication
Authors: McNab Duncan , McKay John , Bowie Paul 
Published: September 2015

Background and objectives Small-scale quality improvement projects are expected to make a significant contribution towards improving the quality of healthcare. Enabling doctors-in-training to design and lead quality improvement projects is important preparation for independent practice. Participation is mandatory in speciality training curricula. However, provision of training and ongoing support in quality improvement methods and practice is variable. We aimed to design and deliver a quality improvement training package to core medical and general practice specialty trainees and evaluate impact in terms of project participation, completion and publication in a healthcare journal. Method A quality improvement training package was developed and delivered to core medical trainees and general practice specialty trainees in the west of Scotland encompassing a 1-day workshop and mentoring during completion of a quality improvement project over 3 months. A mixed methods evaluation was undertaken and data collected via questionnaire surveys, knowledge assessment, and formative assessment of project proposals, completed quality improvement projects and publication success. Results Twenty-three participants attended the training day with 20 submitting a project proposal (87%). Ten completed quality improvement projects (43%), eight were judged as satisfactory (35%), and four were submitted and accepted for journal publication (17%). Knowledge and confidence in aspects of quality improvement improved during the pilot, while early feedback on project proposals was valued (85.7%). Conclusion This small study reports modest success in training core medical trainees and general practice specialty trainees in quality improvement. Many gained knowledge of, confidence in and experience of quality improvement, while journal publication was shown to be possible. The development of educational resources to aid quality improvement project completion and mentoring support is necessary if expectations for quality improvement are to be realised.
(Un)Identified: détourned photographs from modern Siam
Authors: Power Nigel 
Published: September 2015

This visual essay weaves together images from an artistic research project with discussion of the critical and historical contexts which animated and informed it. The images – for the most part – are composites of late 19th and early 20th century photographic portraits discovered by chance in the National Archive of Thailand. In November 2014 these were exhibited at H Project Space, a Bangkok gallery located in a neo-colonial house built by an Anglo-Thai couple around the same time as the photographs were taken. For this, the composites were generated in real time using software designed by the author. These were projected at monumental scale to create two immersive spaces. In the interests of clarity, images from this exhibition and others generated during the visual research process are included here. The inquiry sought to raise questions about overlooked and taboo aspects of Thai history and to relate these to a political present characterised by mass censorship, curtailed freedom of expression and a heavily policed visual culture.
Sand lizard (Lacerta agilis) phenology in a warming world
Authors: Ljungström Gabriella , Wapstra Erik , Olsson Mats 
Published: September 2015

Abstract
Background
Present-day climate change has altered the phenology (the timing of periodic life cycle events) of many plant and animal populations worldwide. Some of these changes have been adaptive, leading to an increase in population fitness, whereas others have been associated with fitness decline. Representing short-term responses to an altered weather regime, hitherto observed changes are largely explained by phenotypic plasticity. However, to track climatically induced shifts in optimal phenotype as climate change proceeds, evolutionary capacity in key limiting climate- and fitness-related traits is likely to be crucial. In order to produce realistic predictions about the effects of climate change on species and populations, a main target for conservation biologists is thus to assess the potential of natural populations to respond by these two mechanisms. In this study we use a large 15-year dataset on an ectotherm model, the Swedish sand lizard (Lacerta agilis), to investigate how higher spring temperature is likely to affect oviposition timing in a high latitude population, a trait strongly linked to offspring fitness and survival.

Results
With an interest in both the short- and potential long-term effect of rising temperatures, we applied a random regression model, which yields estimates of population-level plasticity and among-individual variation in the average, as well as the plastic, response to temperature. Population plasticity represents capacity for short-term adjustments whereas variation among individuals in a fitness-related trait indicates an opportunity for natural selection and hence for evolutionary adaptation. The analysis revealed both population-level plasticity and individual-level variation in average laying date. In contrast, we found no evidence for variation among females in their plastic responses to spring temperature, which could demonstrate a similarity in responses amongst females, but may also be due to a lack of statistical power to detect such an effect.

Conclusion
Our findings indicate that climate warming may have positive fitness effects in this lizard population through an advancement of oviposition date. This prediction is consistent over shorter and potentially also longer time scales as the analysis revealed both population-level plasticity and individual-level variation in average laying date. However, the genetic basis for this variation would have to be examined in order to predict an evolutionary response.

Abstract
Introduction
Saline-based and hydroxyethyl starch solutions are associated with increased risk of renal dysfunction. In the present study, we tested the hypothesis that balanced solutions and a limited volume of hydroxyethyl starch solution (renal protective fluid management [RPF] strategy) would decrease the incidence of postoperative acute kidney injury (AKI) and improve clinical outcomes in patients undergoing off-pump coronary artery bypass graft surgery (OPCAB).

Methods
We investigated 783 patients who underwent elective OPCAB. All patients who underwent OPCAB between 1 January 2010 and 4 July 2012 formed the control group and were given intravenous fluids with saline-based solutions and unlimited volumes of colloid solutions. All patients who underwent OPCAB between 5 July 2012 and 31 December 2013 formed the RPF group and were given intravenous fluids with RPF. The primary outcome was the incidence of postoperative AKI. Secondary outcomes included the incidence of severe AKI, requirement for renal replacement therapy, renal outcome at the time of discharge, and other clinical outcomes.

Results
Postoperative AKI occurred in 33 patients (14.4 %) in the RPF group compared with 210 patients (37.9 %) in the control group (P < 0.001). The incidences of severe AKI and persistent AKI after OPCAB were significantly lower, and the postoperative extubation time and duration of hospital stay were significantly shorter, in patients in the RPF group than in those in the control group. After adjustment by multivariate regression analyses and inverse probability of treatment weighting adjustment, the RPF group was independently associated with a lower incidence of postoperative AKI, severe AKI, and persistent AKI and a shorter postoperative extubation time and duration of hospital stay.

Conclusions
The RPF strategy is associated with a significantly decreased incidence of postoperative, severe, and persistent AKI in patients undergoing OPCAB, although residual confounding may be present.
Executive Summary to EDC-2: The Endocrine Society's Second Scientific Statement on Endocrine-Disrupting Chemicals

Published: September 2015

Abstract
This Executive Summary to the Endocrine Society's second Scientific Statement on environmental endocrine-disrupting chemicals (EDCs) provides a synthesis of the key points of the complete statement. The full Scientific Statement represents a comprehensive review of the literature on seven topics for which there is strong mechanistic, experimental, animal, and epidemiological evidence for endocrine disruption, namely: obesity and diabetes, female reproduction, male reproduction, hormone-sensitive cancers in females, prostate cancer, thyroid, and neurodevelopment and neuroendocrine systems. EDCs such as bisphenol A, phthalates, pesticides, persistent organic pollutants such as polychlorinated biphenyls, polybrominated diethyl ethers, and dioxins were emphasized because these chemicals had the greatest depth and breadth of available information. The Statement also included thorough coverage of studies of developmental exposures to EDCs, especially in the fetus and infant, because these are critical life stages during which perturbations of hormones can increase the probability of a disease or dysfunction later in life. A conclusion of the Statement is that publications over the past 5 years have led to a much fuller understanding of the endocrine principles by which EDCs act, including nonmonotonic dose-responses, low-dose effects, and developmental vulnerability. These findings will prove useful to researchers, physicians, and other healthcare providers in translating the science of endocrine disruption to improved public health.

Published: September 2015

Abstract
To improve the utilization of Li2S active material, an essential increase of Li+ ion conductivity for Li2S itself was investigated by modifying the crystal structure of Li2S. Li2S–LiI solid solutions were prepared by mechanical milling and their ionic conductivities were remarkably increased. All-solid-state cells with Li2S–LiI composite electrodes exhibited the highest utilization of Li2S with high reversibility and cyclability in all-solid-state cells with Li2S reported so far.

Abstract
Low-temperature catalytic oxidation of gaseous 1,2-dichlorobenzene (1,2-DCBz) on V2O5–WO3/TiO2 films was investigated in the presence and absence of ozone and UV irradiation. This paper describes a rapid (1.8 s), low-ozone consuming (190 ppm), and efficient (99.9%) catalytic degradation of 1,2-DCBz at a relatively low temperature (160 °C). The possible underlying mechanisms are also discussed.
