Authors: Damjanovic Domagoj , Goebel Ulrich , Fischer Benedikt , Huth Martin , Breger Hartmut , Buerkle Hartmut , Schmutz Axel
Published: February 2017

Background

Hands-on training in point-of-care ultrasound (POC-US) should ideally comprise bedside teaching, as well as simulated clinical scenarios. High-fidelity phantoms and portable ultrasound simulation systems are commercially available, however, at considerable costs. This limits their suitability for medical schools. A Linux-based software for Emergency Department Ultrasound Simulation (edus2TM) was developed by Kulyk and Olszynski in 2011. Its feasibility for POC-US education has been well-documented, and shows good acceptance. An important limitation to an even more widespread use of edus2, however, may be due to the need for a virtual machine for WINDOWS® systems. Our aim was to adapt the original software toward an HTML-based solution, thus making it affordable and applicable in any simulation setting.

Methods

We created an HTML browser-based ultrasound simulation application, which reads the input of different sensors, triggering an ultrasound video to be displayed on a respective device. RFID tags, NFC tags, and QR Codes™ have been integrated into training phantoms or were attached to standardized patients. The RFID antenna was hidden in a mock ultrasound probe. The application is independent from the respective device.

Results

Our application was used successfully with different trigger/scanner combinations and mounted readily into simulated training scenarios. The application runs independently from operating systems or electronic devices.

Conclusion

This low-cost, browser-based ultrasound simulator is easy-to-build, very adaptive, and independent from operating systems. It has the potential to facilitate POC-US training throughout the world, especially in resource-limited areas.

Published: February 2017

Background

Modern synchrotron light sources and detectors produce data at such scale and complexity that large-scale computation is required to unleash their full power. One of the widely used imaging techniques that generates data at tens of gigabytes per second is computed tomography (CT). Although CT experiments result in rapid data generation, the analysis and reconstruction of the collected data may require hours or even days of computation time with a medium-sized workstation, which hinders the scientific progress that relies on the results of analysis.

Methods

We present Trace, a data-intensive computing engine that we have developed to enable high-performance implementation of iterative tomographic reconstruction algorithms for parallel computers. Trace provides fine-grained reconstruction of tomography datasets using both (thread-level) shared memory and (process-level) distributed memory parallelization. Trace utilizes a special data structure called replicated reconstruction object to maximize application performance. We also present the optimizations that we apply to the replicated reconstruction objects and evaluate them using tomography datasets collected at the Advanced Photon Source.

Results

Our experimental evaluations show that our optimizations and parallelization techniques can provide 158× speedup using 32 compute nodes (384 cores) over a single-core configuration and decrease the end-to-end processing time of a large sinogram (with 4501 × 1 × 22,400 dimensions) from 12.5 h to <5 min per iteration.

Conclusion

The proposed tomographic reconstruction engine can efficiently process large-scale tomographic data using many compute nodes and minimize reconstruction times.
Urban/the City: An Experiment Called the “Kochi Film”
Authors: Radhakrishnan Ratheesh
Published: February 2017

This article, organized around three films—Stop Violence (dir. A. K. Sajan, 2002), Big B (dir. Amal Neerad, 2007), and Annayum Rassolum (dir. Rajeev Ravi, 2013)—attempts to account for a moment in the history of Malayalam cinema when an attempt to spatially imagine, through iterative images, the city as a visible space that was distinct, and situated within the state of Kerala, was undertaken. The “city” in Malayalam cinema is at once mediated by a history of its engagement with aesthetics and economics, as well as the modes with which precolonial, colonial, and postcolonial histories are spatially and temporally arranged. The article attempts to think of the city in Malayalam cinema as a moment of refiguration of its history and practices. The city as location in Malayalam cinema emerges as a negotiation with a specific form of realism anchored in rural anthropology put together in what has been termed the “middlebrow cinema” of the 1980s.
Metabolic rate and hypoxia tolerance are affected by group interactions and sex in the fruit fly (Drosophila melanogaster): new data and a literature survey
Authors: Burggren Warren , Souder BriAnna M. , Ho Dao H.
Published: February 2017

Population density and associated behavioral adjustments are potentially important in regulating physiological performance in many animals. In r-selected species like the fruit fly (Drosophila), where population density rapidly shifts in unpredictable and unstable environments, density-dependent physiological adjustments may aid survival of individuals living in a social environment. Yet, how population density (and associated social behaviors) affects physiological functions like metabolism is poorly understood in insects. Additionally, insects often show marked sexual dimorphism (larger females). Thus, in this study on D. melanogaster, we characterized the effects of fly density and sex on both mass-specific routine oxygen consumption (V̇O2) and hypoxia tolerance (PCrit). Females had significantly lower routine V̇O2 (∼4 μl O2·mg−1·h−1) than males (∼6 μl O2·mg−1·h−1) at an average fly density of 28 flies·respirometer chamber−1. However, V̇O2 was inversely related to fly density in males, with V̇O2 ranging from 4 to 11 μl O2·mg−1·h−1 at a density of 10 and 40 flies·chamber−1, respectively (r2=0.58, P<0.001). Female flies showed a similar but less pronounced effect, with a V̇O2 of 4 and 7 μl O2·mg−1·h−1 at a density of 10 and 40 flies·chamber−1, respectively (r2=0.43, P<0.001). PCrit (∼5.5 to 7.5 kPa) varied significantly with density in male (r2=0.50, P<0.01) but not female (r2=0.02, P>0.5) flies, with higher fly densities having lower PCrits. An extensive survey of the literature on metabolism in fruit flies indicates that not all studies control for, or even report on, fly density and gender, both of which may affect metabolic measurements.
Super-resolution mapping of scaffold nucleoporins in the nuclear pore complex
Authors: Ma Jiong , Kelich Joseph M. , Junod Samuel L. , Yang Weidong
Published: February 2017

The nuclear pore complex (NPC), composed of ∼30 different nucleoporins (Nups), is one of the largest supramolecular structures in eukaryotic cells. Its octagonal ring scaffold perforates the nuclear envelope and features a unique molecular machinery that regulates nucleocytoplasmic transport. However, the precise copy number and the spatial location of each Nup in the native NPC remain obscure due to the inherent difficulty of counting and localizing proteins inside of the sub-micrometer supramolecular complex. Here, we combined super-resolution single-point edge-excitation subdiffraction (SPEED) microscopy and nanobody-specific labeling to reveal the spatial distribution of scaffold Nups within three separate layers in the native NPC with a precision of ∼3 nm. Our data reveal both the radial and axial spatial distributions for Pom121, Nup37 and Nup35 and provide evidence for their copy numbers of 8, 32 and 16, respectively, per NPC. This approach can help pave the path for mapping the entirety of Nups in native NPCs and also other structural components of macromolecular complexes.
Corneal epithelial stem cells and their niche at a glance
Authors: Nowell Craig S. , Radtke Freddy
Published: February 2017

The corneal epithelium acts as a protective barrier on the anterior ocular surface and is essential for maintaining transparency of the cornea and thus visual acuity. During both homeostasis and repair, the corneal epithelium is maintained by self-renewing stem cells, which persist throughout the lifetime of the organism. Importantly, as in other self-renewing tissues, the functional activity of corneal epithelial stem cells (CSCEs) is tightly regulated by the surrounding microenvironment, or niche, which provides a range of cues that maintain the stem cell population. This Cell Science at a Glance article and the accompanying poster will therefore aim to summarise our current understanding of the corneal epithelial stem cell niche and its role in regulating stem cell activity during homeostasis, repair and disease.
“Was Pyrrho a Pyrrhonian?”
Authors: Green Jerry
Published: February 2017

This paper attempts a reconstruction of the views of Pyrrho of Elis. Many recent commentators, most notably Richard Bett, have made Pyrrho out to a metaphysical dogmatist who thinks the world is fundamentally indeterminate. Despite some criticisms of this view by Brennan and others, this metaphysical reading has continued to gain adherents. But there are serious textual and logical problems with these dogmatic interpretations. According to the evidence we have, a better view is that Pyrrho was an agnostic skeptic, i.e. one who refused to make assertions about the world outside of perceptual or intellectual appearances. But this does not mean that the traditional view of Pyrrho is correct either: the kind of skepticism Pyrrho endorsed is not Pyrrhonian, because it is grounded in the nature of our epistemic faculties rather than opposition between equally plausible theories, arguments, beliefs, or appearances. A secondary thesis of this paper is about methodology. Rather than focus on the most ambiguous and contentious passages in isolation, we should base our interpretation on the whole corpus, beginning with the easiest passages. Faulty interpretations of Pyrrho go wrong, I argue, partly by failing to follow this method.
Relations of density, polyethylene glycol treatment and moisture content with stiffness properties of Vasa oak samples
Authors: Vorobyev Alexey , Almkvist Gunnar , van Dijk Nico P. , Gamstedt E. Kristofer
Published: February 2017

Treatment with polyethylene glycol (PEG) is the preferred method for the conservation of waterlogged archaeological wooden objects. However, PEG impregnation leads to softening and increased hygroscopicity of the material. The present study compiles experimental results concerning the full elastic properties of PEG impregnated archaeological wood from the Vasa ship in relation to its basic density, PEG content (PEGC) and moisture content (MC). The results show a correlation between a more porous microstructure and high PEGC, and consequently, higher MC. The PEG and moisture contribute to the mass of the wooden object as well as to the softening of the material, which are undesired properties in a larger load-carrying wooden structure. A compromise between the improved dimensional stability and degradation of mechanical properties should therefore be considered in the conservation of wooden objects treated with PEG.
Ordered, Disordered and Partially Synchronized Schools of Fish
Authors: Birnir Björn , Einarsson Baldvin , Bonilla Luis L. , Cornejo-Donoso Jorge
Published: February 2017

We study the properties of an ODE description of schools of fish (B. Birnir, An ODE model of the motion of pelagic fish, J. Stat. Phys. 128(1/2) (2007), 535–568.) and how they change in the presence of a random acceleration. The model can be reduced to one ODE for the direction of the velocity of a generic fish and another ODE for its speed. These equations contain the mean speed

v
ˉ

$\bar{v}$

and a Kuramoto order parameter

r

$r$

for the phases of the fish velocities. In this paper, we give a complete qualitative analysis of the system for large number of particles. We show that the stationary solutions of the ODEs consist of an incoherent unstable solution with

r

=

v
ˉ

=

0

$r\!\!=\!\!\bar{v}\!\!=\!\!0$

and a globally stable solution with

r

1

$r\!=\!1$

and a constant

v
ˉ

0

$\bar{v}\!>\!0$

. In the latter solution, all the fish move uniformly in the same direction with

v
ˉ

$\bar{v}$

and the direction of motion determined by the initial configuration of the school. This is called the “migratory solution”. In the second part of the paper, the directional headings of the particles are perturbed, in two distinct ways, and the speeds accelerated in order to obtain two distinct classes of non-stationary, complex solutions. We show that the perturbed systems have similar behavior as the unperturbed one, and derive the resulting constant value of the average speed, verifying the numerical observations. Finally, we show that the system exhibits a similar bifurcation to that in Vicsek and Czirok (T. Vicsek, A. Czirók, E. Ben-Jacob, I. Cohen and O. Shochet, Novel type of phase transition in a system of self-driven particles, Phys. Rev. Lett. 75(6) (Aug 1995), 1226–1229.) between phases of synchronization and disorder. Either increasing the variance of the Brownian angular noise, or decreasing the turning rate, or coupling between the particles, cause a similar phase transition. These perturbed models represent a more realistic view of schools of fish found in nature. We apply the theory to compute the order parameter for a simulation of the Chile-Peru anchovy fishery.
The Tasks of Climate Related Energy Ethics – The Example of Carbon Capture and Storage
Authors: Steigleder Klaus
Published: February 2017

In this article I try to show that climate ethics must be to a great extent risk and energy ethics. As the emissions of carbon dioxide have to be stopped completely in a relatively short period of time a massive change of global energy systems is needed. Scenarios of how this can realistically be achieved must be developed and evaluated. The required transformations potentially conflict with the important aims of energy security, economic development and overcoming energy poverty. Proposed measures may involve unacceptable risks or be counterproductive. Criteria, principles and guidelines are proposed which are needed to deal with these problems. Finally, the difficulties and tasks of climate related energy ethics are critically exemplified on the strategy of comprehensive carbon capture and storage, a strategy which is part of almost all scenarios which aim at restricting the increase of the average global temperature to 2° C.
On the estimation of regime-switching Lévy models
Authors: Chevallier Julien , Goutte Stéphane
Published: February 2017

The regime-switching Lévy model combines jump-diffusion under the form of a Lévy process, and Markov regime-switching where all parameters depend on the value of a continuous time Markov chain. We start by giving general stochastic results. Estimation is performed following a two-step procedure. The EM-algorithm is extended to this new class of jump-diffusion regime-switching models. Simulations are proposed, alongside an empirical application dedicated to the study of financial and commodity time series. When comparing the results with (i) non regime-switching models, and (ii) continuous regime-switching models (where the Lévy process is replaced by a classic Brownian motion), the Lévy regime-switching model outperforms other competitors.
Context-Dependent Modulation of Excitatory Synaptic Strength by Synaptically Released Zinc
Authors: Kalappa Bopanna I. , Tzounopoulos Thanos
Published: February 2017

Synaptically released zinc inhibits baseline excitatory neurotransmission; however, the role of this neuromodulator on short-term plasticity during different levels of synaptic activity remains largely unknown. This lack of knowledge prevents our understanding of information transfer across zinc-releasing synapses, including 50% of excitatory synapses in cortical areas. We usedin vitroelectrophysiology in mouse brain slices and discovered that the effects of zinc on excitatory postsynaptic current (EPSC) amplitudes are context-dependent. At lower frequencies of activity, synaptically released zinc reduces EPSC amplitudes. In contrast, at higher stimulation frequencies and vesicular release probability (Pr), zinc inhibits EPSC amplitudes during the first few stimuli but leads to enhanced steady-state EPSC amplitudes during subsequent stimuli. This paradoxical enhancement is due to zinc-dependent potentiation of synaptic facilitation via the recruitment of endocannabinoid signaling. Together, these findings demonstrate that synaptically released zinc is a modulator of excitatory short-term plasticity, which shapes information transfer among excitatory synapses.
Axonal Type III Nrg1 Controls Glutamate Synapse Formation and GluA2 Trafficking in Hippocampal-Accumbens Connections
Authors: Zhong Chongbo , Akmentin Wendy , Du Chuang , Role Lorna W. , Talmage David A.
Published: February 2017

Altered neuregulin 1 (Nrg1)/ErbB signaling and glutamatergic hypofunction have been implicated in the pathophysiology of schizophrenia. Here, we employed gene chimeric ventral hippocampus (vHipp)-nucleus accumbens (nAcc) coculture from mouse, electrophysiology, immunocytochemistry, FM1-43 vesicle fusion, and electron microscopy techniques to examine the pre- and postsynaptic mechanisms of genetic deficits in Nrg1/ErbB signaling-induced glutamatergic dysfunctions. Reduced presynaptic type III Nrg1 expression along vHipp axons decreases the number of glutamate synapses and impairs GluA2 trafficking in the postsynaptic nAcc neurons, resulting in decreased frequency and amplitude of miniature EPSCs (mEPSCs). Reduced expression of axonal type III Nrg1 along vHipp projections also decreases functional synaptic vesicle (SV) clustering and vesicular trafficking to presynaptic vHipp axonal terminals. These findings suggest that Nrg1/ErbB signaling modulate glutamatergic transmission via both pre- and postsynaptic mechanisms.

Transformed Neural Pattern Reinstatement during Episodic Memory Retrieval
Authors: Xiao Xiaoqian , Dong Qi , Gao Jiahong , Men Weiwei , Poldrack Russell A. , Xue Gui
Published: February 2017

Contemporary models of episodic memory posit that remembering involves the reenactment of encoding processes. Although encoding-retrieval similarity has been consistently reported and linked to memory success, the nature of neural pattern reinstatement is poorly understood. Using high-resolution fMRI on human subjects, our results obtained clear evidence for item-specific pattern reinstatement in the frontoparietal cortex, even when the encoding-retrieval pairs shared no perceptual similarity. No item-specific pattern reinstatement was found in the ventral visual cortex. Importantly, the brain regions and voxels carrying item-specific representation differed significantly between encoding and retrieval, and the item specificity for encoding-retrieval similarity was smaller than that for encoding or retrieval, suggesting different nature of representations between encoding and retrieval. Moreover, cross-region representational similarity analysis suggests that the encoded representation in the ventral visual cortex was reinstated in the frontoparietal cortex during retrieval. Together, these results suggest that, in addition to reinstatement of the originally encoded pattern in the brain regions that perform encoding processes, retrieval may also involve the reinstatement of a transformed representation of the encoded information. These results emphasize the constructive nature of memory retrieval that helps to serve important adaptive functions.

SIGNIFICANCE STATEMENTEpisodic memory enables humans to vividly reexperience past events, yet how this is achieved at the neural level is barely understood. A long-standing hypothesis posits that memory retrieval involves the faithful reinstatement of encoding-related activity. We tested this hypothesis by comparing the neural representations during encoding and retrieval. We found strong pattern reinstatement in the frontoparietal cortex, but not in the ventral visual cortex, that represents visual details. Critically, even within the same brain regions, the nature of representation during retrieval was qualitatively different from that during encoding. These results suggest that memory retrieval is not a faithful replay of past event but rather involves additional constructive processes to serve adaptive functions.
Building Mulholland Highway: The Road to Mulholland Drive
Authors: Read Barry
Published: February 2017

The scenic highway along the crest of the Santa Monica Mountains that became Mulholland Drive was the brainchild of a group of large property owners, speculators, developers, financiers, and business leaders. This group, organized as the Hollywood Foothills Improvement Association, donated the land for the right-of-way, directed the survey and engineering studies for the roadway, lobbied city officials, convinced small property-holders to approve a municipal improvement district to fund it, and won public support for the project. The scenic drive fostered its members’ real estate goals and the value of their investments. It also promoted tourism in the region and reduced the mountain barrier that had divided the City of Los Angeles from its San Fernando Valley extension.
“No Ku Klux Klan for Kern”
Authors: Rodriquez Alicia E.
Published: February 2017

The Ku Klux Klan saw a rapid rise in Kern County, California, in 1921 but disintegrated in 1922. Local newspapers decried the Klan’s vigilante violence; a diligent district attorney pursued and prosecuted those involved; and the local press and the court cases revealed members’ identities. The ensuing backlash quickly neutralized the Klan in Kern County. The revealed identities enabled the author to profile local KKK adherents. The subsequent career paths of key members and their opponents confirm the shift of public opinion against the Klan despite its public relations efforts.

Resumo O Conselho Municipal de Saúde é uma instância colegiada de participação social no campo das políticas públicas em saúde. De caráter representativo e deliberativo, o conselho é formado por usuários, trabalhadores e gestores do setor da saúde em esfera municipal. Este artigo busca descrever a participação do segmento desses trabalhadores no Conselho Municipal de um município de grande porte da região metropolitana de São Paulo, identificando os fatores que podem se constituir em entraves à efetiva participação dos representantes deste segmento. A abordagem foi qualitativa e a coleta de dados feita por meio de análise documental, da observação de reuniões do Conselho e de entrevistas semiestruturadas. Como resultado, verificou-se que os conselheiros não identificam com clareza os representantes do segmento dos trabalhadores no conselho, desconhecem o papel deste segmento e apresentam uma expectativa sobre o papel técnico-científico a ser desempenhado por eles. No município de Guarulhos, de forma peculiar, denomina-se “promotores da saúde” o conjunto desses trabalhadores e gestores. Observou-se que isso contribuiu para a diluição de seu papel, acentuando os entraves e obstáculos à efetiva participação da sociedade civil nas decisões relativas às políticas de saúde locais.

However, forecasting results though the Tourist Information System showed that the number of tourists decreased. This study proposes practical implications based on these results.
Advertising Effects of Tourism Products on a Social Commerce Site According to the Message Type and Perceived Uncertainty
Authors:   The Tourism Sciences Society Of Korea, Yoon Ahyoung , Yoon Ji-Hwan
Published: February 2017

As competition between travel agencies on social commerce sites continues to escalate, travel agencies currently need to produce effective advertisements. Since there is little difference in both the price and composition of tour products sold at social commerce sites, it might be difficult to differentiate each product from its many other competitors. Throughout this study, widely used message framing and scarcity message strategies were used to measure advertising effectiveness to overcome these problems. In addition, perceived uncertainty was used as a moderating variable to verify whether the level of uncertainty (high vs. low) consumers perceive influences their purchase intention. 2(message framing: profit vs. loss) × 2(scarcity message: quantitative vs. temporal) mixed factorial design was composed, and the perceived value was divided into two groups(low vs. high). The results revealed that for the low-perceived uncertainty group, profit-message framing was more effective on purchase intention. However, for the high-perceived uncertainty group, loss-message framing was more effective. In terms of scarcity message, a quantitative limited message encouraged consumers’ purchase intention more than a temporal limited message regardless of the level of uncertainty.
La salud bucal como derecho humano y bien ético
Authors: Rueda Martínez Gabriela , Albuquerque Aline
Published: February 2017

Fue ejecutado un examen del Reporte Mundial de Salud Bucal, adoptado por el Programa de Salud Bucal Global de la OMS, con el objetivo de determinar si este documento se constituye en una herramienta teórico-política para alcanzar la realización del derecho a la salud bucal. La metodología empleada fue el análisis de prácticas discursivas, formulado por Spink, aplicado a un documento de dominio público. El análisis constató que el Reporte Mundial de Salud Bucal no se constituye en una herramienta política-teórica para la satisfacción del derecho a la salud bucal, en razón a que no incorpora el enfoque basado en los derechos humanos; la perspectiva de este documento es limitada a los cuidados en salud bucal, no establece mecanismos para el efectivo enfrentamiento de los determinantes sociales y las obligaciones estatales de asegurar el derecho a la salud bucal, no son enfatizadas. Al alejarse del referencial de los derechos humanos, también se distancia de la Bioética, en razón de que se desconsidera al paciente en sus múltiples contextos, que permean el proceso salud-enfermedad; así, es contrario a la promoción de condiciones de vidas justas y ecuánimes para los individuos.
Consideraciones del bioderecho sobre la eutanasia en Colombia
Authors: García Pereáñez José Antonio
Published: February 2017

Este artículo aborda de manera reflexiva las incidencias del bioderecho sobre situaciones de eutanasia en Colombia, al interpretar conflictos morales y jurídicos suscitados por las sentencias de la Corte Constitucional C239 de 1997, T970 de 2014 y la Resolución del Ministerio de Salud y Protección Social 1216, de 2015. El propósito fundamental es el análisis de las decisiones judiciales sobre el final de la vida humana. Por lo tanto, se realiza una revisión de la construcción histórica y jurídica del concepto de eutanasia y se propone la discusión sobre su manejo jurídico y su influencia en el colectivo moral. Asimismo, se diserta sobre el concepto de dignidad humana y muerte digna, como precedentes para dirimir los conflictos éticos que la eutanasia suscita. Al final, se analiza el caso de don Ovidio González, quien se convirtió en 2015 en el primer colombiano en recibir la eutanasia de manera legal dentro del sistema de salud.

EMDR Therapy Reduces Intense Treatment-Resistant Cravings in a Case of Gamma-Hydroxybutyric Acid Addiction
Authors: Qurishi Rouhollah , Markus Wiebren , Habra Maaike M.J. , Bressers Bibi , De Jong Cornelis A.J.
Published: February 2017

This article presents the first experiences of using eye movement desensitization and reprocessing (EMDR) therapy to aid in the treatment of gamma-hydroxybutyric acid (GHB) dependency. A case presented itself as a result of intense, treatment-resistant cravings despite pharmacological treatment. The patient received 7 weekly sessions using a subset of the palette of EMDR interventions in addiction (PEIA; Markus & Hornsveld, 2017) targeting both negative and positive valenced addiction-related memory representations from the past, present, and future. Patient-reported GHB craving showed a gradual and prolonged reduction. Urine samples showed that the patient remained abstinent during and at least 6 months after EMDR therapy. Further research regarding the effectiveness of EMDR therapy in this particularly challenging group of substance users is warranted.
Dynamic Assessment of Figurative Language of Children in the Autistic Spectrum: The Relation to Some Cognitive and Language Aspects
Authors: Tzuriel David , Groman Tamar
Published: February 2017

The objectives of this study were to examine (a) differences in figurative language, analogical reasoning, executive functions (EF), theory of mind (ToM), and local/central coherence (LCC) of children with high-functioning autism (HFA; n = 32) and typically developing (TD; n = 32) children; (b) improvement of figurative language using dynamic assessment; and (c) prediction of proverbial understanding by the cognitive variables. A sample of 5- to 11-year-old children with HFA was pair matched with a group of TD children on age, gender, vocabulary, and socioeconomic status (SES). Participants were administered tests of proverbial understanding, metaphorical construction, analogies, language ability, EF, LCC, and ToM. TD children scored higher than children with HFA on all tests. In the HFA group, proverbial understanding was predicted by LCC and verbal ability and in the TD group by metaphorical construction and EF. These findings refute the argument that figurative language among HFA is a function of only verbal ability.

ABSTRACT

Study of parasites inventory on ornamental fish transported in Soekarno-Hatta Airport, Cengkareng, Jakarta was done.  Parasites were identified from coral platy fish (Xiphophorus maculatus), guppy cobra fish (Poecilia reticulata), red nose tetra fish (Hemigrammus rhodostomus) and serpe minor fish (Hyphessobrycon serpae).  Parasites found from coral platy fish were identified as Dactylogyrus  and Argulus japonicus; Trichodina heterodentata and Lerneae infected guppy cobra fish;  red nose tetra fish was infected by Gyrodactylus, whilst Ichthyoph-thirius multifiliis were found in serpe minor fish only. All of the parasites were known as ectoparasites and excluded from the List of Pest and Parasite Fish Quarantine. From this study, there was a correlation between present of parasites with length of fish.

Key words : Ornamental fish, fish parasites, fish quarantine

Turismo termal como opción de turismo de bienestar en Colombia: un estudio exploratorio
Authors: Pineda-Escobar Maria Alejandra , Falla Villa Paola Liliana
Published: February 2017

Colombia ha identificado el turismo como uno de los sectores de la economía nacional con mayor potencial para mejorar la productividad nacional, lo que convierte al subsector del turismo de salud y bienestar en una de las áreas estratégicas de particular interés. Sin embargo, el conocimiento disponible acerca de las alternativas de turismo de bienestar en el país es aún incipiente, por lo cual la academia nacional debe generar respuestas que ayuden a nutrir esta necesidad de conocimiento. En este contexto, mediante la aplicación de una metodología de investigación cualitativa exploratoria, a través de la observación participante, el presente estudio analiza la oferta de termales y aguas medicinales como alternativas que pueden tener un potencial para el turismo de bienestar en Colombia. Para esto, se eligieron y analizaron como casos de estudio los municipios de Nuquí, Aguascalientes y Machetá. La investigación permite comparar los ambientes explorados y ofrecer recomendaciones preliminares como fruto de dicho estudio.
El crecimiento de las empresas establecidas. Un caso de estudio del sector de fabricación de carrocerías en Ecuador abordado desde la perspectiva financiera
Authors: Morales Carrasco Lilián Victoria , Valle Álvarez Alexandra Tatiana , Freire Torres Alva Verónica , Silva Ortiz Paola Karina
Published: February 2017

El presente estudio aborda los factores internos de índole financiera que se relacionan con el comportamiento financiero en la estrategia de expansión de las empresas. Para abordar el problema de investigación, se seleccionaron empresas representativas del sector de fabricación de carrocerías. Se aplicó un análisis estadístico de correlación a tres escenarios de medición del crecimiento; en cada escenario, las variables dependientes ventas, utilidad y capacidad instalada se relacionaron con índices financieros que funcionaron como variables independientes. El análisis descriptivo identificó dos grupos con respecto a la edad de las empresas: en uno, la edad oscila entre 26 y 49 años, para las más longevas, mientras que en el otro grupo las más jóvenes presentan una edad inferior a 26 años. Las empresas estudiadas nacieron como micro y pequeñas empresas, y alcanzaron una dimensión de medianas empresas, medida por el número de trabajadores. Los principales resultados de la investigación muestran altas correlaciones en tres escenarios que indican que la gestión financiera, como factor interno de crecimiento, es decisiva en el momento de analizar el crecimiento de las pymes establecidas del sector de fabricación de carrocerías en el caso de Tungurahua, Ecuador.

Incidencia de las juntas de acción comunal en el desarrollo local en áreas de influencia de proyectos de hidrocarburos
Authors: Sánchez Castañeda July Marcela , Prieto Amanda Vargas
Published: February 2017

Community action groups (CAGs), as non-profit civil organizations that voluntarily participate in a joint effort in the pursuit of a common goal, have been the driving force behind the development of paths, small towns and neighborhoods in recent decades. In Colombia there are about 45,000. The objective of the present study is to learn about the role of CAGs in local development. The methodology used was the case study of the CAGs of neighborhoods Evaristo Sourdis, La Unión and San Carlos (second phase), in Sabanalarga, Atlántico, Colombia. Characterized by its location, its processes and its proximity to the recent development of the oil industry in the town. The results present the characterization of the CAGs, their organizational processes, their actions towards development and its relationship with the new actors of the territory, in this case, the recent oil industry in the town. It is thus concluded that CAGs have an impact on local development processes, regardless of other actors in their territories, since their main goal is the improvement of the living conditions of the town.

Authors: Bernal Chávez Julio Alexander , Díaz Romero Camilo Enrique
Published: February 2017

En este panorama se presentan las características más generales del español hablado en Colombia, en especial, en los niveles fonológico, morfológico y sintáctico. Se exponen, en primer lugar, una contextualización sobre los estudios del español que se usa en el país y las propiedades que son comunes a la mayoría de los hispanohablantes colombianos. En segundo lugar, siguiendo la división diatópica propuesta por Montes (1982), se hace mención de las particularidades lingüísticas de cada superdialecto. Por último, se muestran las cualidades del español hablado en zonas de contacto con las lenguas indígenas y se postulan algunas de las tareas pendientes de investigación sobre las diferentes variedades diatópicas y de contacto de la lengua oficial en el nivel nacional.
