Desarrollo de la Competencia de Trabajo en Equipo en la Asignatura de Dirección de Producción y Operaciones
Authors: Estelles-Miguel Sofía , Albarracín Guillem José Miguel , Palmer Gato Marta Elena , Peris-Ortiz Marta 
Published: July 2017

El trabajo en equipo se ha convertido en una exigencia en el mercado laboral. Esto es debido a que los cambios, la incorporación de tecnologías y los nuevos procesos dentro de las organizaciones hacen que las tareas sean cada vez más complejas y en muchas ocasiones no es posible realizar una resolución individual de las mismas. Por todo esto, en la mayoría de las organizaciones se pretende crear una cultura de colaboración, como la mejor estrategia para la resolución de problemas. Sin embargo, la educación que debería promover la cooperación y el trabajo en equipo, actualmente todavía promueve la competitividad. En base a todo esto, se ha desarrollado una experiencia de trabajo en equipo en la asignatura de Dirección de Producción y Operaciones y el presente trabajo presenta los resultados de la misma.
Symbiotic Space: Exploring the Nexus of Rigor, Problems of Practice and Implementation
Authors: Kochhar-Bryant Carol A. 
Published: July 2017

Across the United States, doctoral programs in education are in deep reflection about their purpose, content, and expected outcomes for graduates. Many are in the throes of redesign and testing to better differentiate between two pathways to the doctorate—one for scholars preparing for research and academic roles and one for scholar-practitioners who wish to focus on problems of practice and implementation. This paper explores a major source of challenge among faculty as they engineer both research-oriented and practitioner-oriented degrees, and that is the interconnections among the constructs of rigor, problems of practice, and implementation. The paper examines the tension between the “gold standard” of random assignment studies and causal inferences, and the more recent frames of inquiry in which research is translated to practice through shared pathways that engage multiple stakeholders. Several questions are explored: Are “rigor” and “relevance” opposing constructs? What is rigor and should there be a new standard for scholars navigating within a symbiotic space – the arena in which they seek to impact highly complex social problems within authentic field-based settings? Is rigor subjective, or can it be measured? These questions are examined within the context of implementation science and through the lens of the lived experience of Education faculty who find themselves in a creative crucible as they navigate the redesign process.
Just Who Is John Galt, Anyway? A Carnivalesque Approach toAtlas Shrugged
Authors: Duncan Charles 
Published: July 2017

AbstractBased on a paper delivered at a conference devoted to carnivalesque studies, this article focuses attention on Rand's masterwork, Atlas Shrugged. By utilizing the carnivalesque techniques of Menippean satire and the “dialogic” interplay of narrative voices, with trickster-heroes as the agents of social change, the author argues that Rand ruthlessly deconstructs the logic of command economies and models a society turned, as Bakhtin would say, “topsy turvy” in favor of pure free enterprise. In doing so, she also contests the political boundaries of a stereotypically left-wing genre whose scholars are also typically Marxian.
The Beneficiary Statement and Beyond
Authors: Jetton Merlin 
Published: July 2017

Abstract
The beneficiary statement refers to a passage in the Introduction of The Virtue of Selfishness. It concerns who the beneficiary of an action should be and any breach between actor and beneficiary. This article critiques said passage and shows how rational self-interest extends beyond the actor's self-interest more narrowly conceived. It critiques the Trader Principle and shows further how trade extends rational self-interest beyond the actor's self-interest more narrowly conceived. It shows how the virtue of independence does not imply that all dependence is a vice. Dependence in collaborative action even extends to the virtue of productiveness.
Ultimate Value: Self-Contradictory
Authors: Hartford Robert 
Published: July 2017

Abstract
Ever since Ayn Rand's groundbreaking analysis of life and value, and her formulation of the Objectivist ethics, controversy has been generated over the relation between the “choice to live” and the status of life as the “ultimate value.” The author argues that the concept “Value” should be modified to denote “that which [an organism] acts to gain and/or keep” that serves as the means to a further end. Deeper analysis shows that the term “ultimate value” is self-contradictory and has been detrimental to the study of the foundations of the Objectivist ethical theory.
Debunking Ecofundamentalism
Authors: Gissurarson Hannes H. 
Published: July 2017

Abstract
Rögnvaldur Hannesson, an international authority on natural resource management, has written a well-argued book against ecofundamentalism, which, for him, puts nature before man. He cogently discusses the problems of applying notions of sustainability and biodiversity to the human condition and suggests that in the foreseeable future fossil fuels should still be utilized as energy sources. Hannesson regards models of global warming as scientific but as too uncertain for mankind to radically alter its ways of life. But he does not distinguish clearly between reasonable environmentalists and the real ecofundamentalists who disguise conflicts between themselves and others as conflicts between man and nature.
Reply to Roger E. Bissell: Thinking Volition
Authors: Jetton Merlin 
Published: July 2017

Abstract
The author agrees with much of Roger E. Bissell's critique of the Objectivist idea of volition (in his July 2015 essay, “Where There's a Will, There's a ‘Why’: A Critique of the Objectivist Theory of Volition”), especially as expressed by Leonard Peikoff. On the other hand, the author believes Bissell's reform of the Objectivist conception is at best minimal and it lacks attention to thinking as an integral part of volition.
The Geopolitical Economy of the Global Internet Infrastructure
Authors: Winseck Dwayne 
Published: July 2017

AbstractAccording to many observers, economic globalization and the liberalization of telecoms/internet policy have remade the world in the image of the United States. The dominant roles of Amazon, Apple, Facebook, and Google have also led to charges of US internet imperialism. This article, however, argues that while these internet giants dominate some of the most popular internet services, the ownership and control of core elements of the internet infrastructure—submarine cables, internet exchange points, autonomous system numbers, datacenters, and so on—are tilting increasingly toward the EU and BRICS (i.e., Brazil, Russia, India, China, and South Africa) countries and the rest of the world, complicating views of hegemonic US control of the internet and what Susan Strange calls the knowledge structure.
Taxonomy, systematics and biology of the Australian halotolerant wolf spider genus Tetralycosa (Araneae: Lycosidae: Artoriinae)
Authors: Framenau Volker W. , Hudson Peter 
Published: July 2017

The Australian wolf spider genus Tftralycosa Roewer, 1960, with Lycosa meracula Simon, 1909 (junior synonym of Lycosa oraria L. Koch, 1877) as type species, is revised to include 13 species, eight of which are described as new here: Tetralycosa adarca sp. nov., T. alteripa (McKay, 1976), T. arabanae Framenau, Gotch & Austin, 2006, T. baudinettei sp. nov., T. caudex sp. nov., T. eyrei (Hickman, 1944), T. floundersi sp. nov., T. halophila sp. nov., T. oraria (L. Koch, 1876), T. orariola sp. nov., T. williamsi sp. nov., T. wundurra (McKay, 1979) comb. nov. and T. rebecca sp. nov. Members of Tetralycosa are halotolerant, exclusively inhabiting saline environments such as coastal beaches, and mound springs, clay pans and salt lakes in the Australian interior. A phylogenetic analysis of the genus identified a monophyletic clade of eight species that live permanently on the barren surface of salt lakes suggesting a single radiation into this extremely inhospitable habitat. Some of these Tetralycosa species are currently known from single salt lakes only and with increasing disturbances of these systems by mining, agriculture and recreational use, research effort should be increased to study their ecology and conservation status.
L’innovation religieuse en question
Authors: Perreault Jean-Philippe 
Published: July 2017

Au point de départ de cette réflexion sur l’innovation religieuse, deux considérations : d’une part, il existe nécessairement de la nouveauté et de la créativité religieuses dans la mesure où les religions évoluent, s’adaptent et demeurent vivantes ; d’autre part, la jeunesse est elle-même pensée et construite comme source de nouveauté et de progrès. L’innovation religieuse se trouve conséquemment au centre du thème de recherche « jeunes et religions ». Sous forme de « notes de recherche », l’intention ici est d’identifier quelques repères permettant une problématisation de la question de l’innovation religieuse dans l’étude du rapport des jeunes aux religions. Pour ce faire, nous interrogerons les conditions d’une telle innovation, tant sur le plan empirique qu’épistémologique : de quelle innovation est-il question, qui innove et innove en regard de quoi ? Quelle épreuve épistémologique devrions-nous faire subir aux principaux concepts pour nous assurer de leur opérationnalité, de leur fécondité et de leur scientificité pour nos travaux ?
Unmixing detrital geochronology age distributions
Authors: Sundell Kurt E. , Saylor Joel E. 
Published: July 2017

AbstractDespite recent advances in quantitative methods of detrital provenance analysis, there is currently no widely accepted method of unmixing detrital geochronology age distributions. We developed a model that determines mixing proportions for source samples through inverse Monte Carlo modeling, wherein mixed samples are compared to randomly generated combinations of source distributions, and a range of best mixing proportions are retained. Results may then be used to constrain a forward optimization routine to find a single best‐fit mixture. Quantitative comparison is based on the Kolmogorov‐Smirnov (KS) testDstatistic and Kuiper testVstatistic for cumulative distribution functions, and the Cross‐correlation coefficient for finite mixture distributions (probability density plots or kernel density estimates). We demonstrate the capacity of this model through a series of tests on synthetic data, and published empirical data from North America mixed in known proportions; this proof‐of‐concept testing shows the model is capable of accurately unmixing highly complex distributions. We apply the model to two published empirical data sets mixed in unknown proportions from Colombia and central China. Neither example yields perfect model fits, which provides a cautionary note of potentially inadequate characterization of source and/or mixed samples, and highlights the importance of such characterization for accurate interpretation of sediment provenance. Sample size appears to be a major control on mixture model results; small (n < 100) samples may lead to misinterpretation. The model is available as a MATLAB‐based stand‐alone executable (.exe file) graphical user interface.
Why was the arid and semiarid northwest China getting wetter in the recent decades?
Authors: Peng Dongdong , Zhou Tianjun 
Published: July 2017

AbstractThe arid and semiarid northwest China has experienced a significant wetting trend in summer during 1961–2010, but the reasons remain ambiguous. In this study, moisture budget analysis is employed to quantify the contributions of different factors to the wetting trend. The results show that more than 50% of the increasing precipitation is balanced by the increased evaporation. The convergence of moisture flux (the sum of horizontal moisture advection and wind convergence terms) has a significant positive contribution to the wetting trend. The increased net surface radiation, which is contributed by the increased downward longwave radiation, supplies more energy to favor the evaporation process of vaporization. The moisture flux convergence is further separated into thermodynamic component in association with changes in specific humidity and dynamic component due to changes in atmospheric circulation. The thermodynamic contribution to the wetting trend is induced by the increased specific humidity which is associated with enhanced evaporation. The dynamic contribution is dominated by an anomalous cyclone over central Asia. The anomalous cyclone is related with intensified horizontal vorticity advection which is associated with a significant southward displacement of Asian subtropical westerly jet. The results indicate that the changes of evaporation against the background of global warming deserve more attention in projecting the climate change in arid and semiarid regions.
High‐resolution chronology of sediment below CCD based on Holocene paleomagnetic secular variations in the Tohoku‐oki earthquake rupture zone
Authors: Kanamatsu Toshiya , Usami Kazuko , McHugh Cecilia M. G. , Ikehara Ken 
Published: July 2017

AbstractUsing high‐resolution paleomagnetic data, we examined the potential for obtaining precise ages from sediment core samples recovered from deep‐sea basins close to rupture zones of the 2011 and earlier earthquakes off Tohoku, Japan. Obtaining detailed stratigraphic ages from deep‐sea sediments below the calcium compensation depth (CCD) is difficult, but we found that the samples contain excellent paleomagnetic secular variation records to constrain age models. Variations in paleomagnetic directions obtained from the sediments reveal systematic changes in the cores. A stacked paleomagnetic profile closely matches the Lake Biwa data sets in southwest Japan for the past 7000 years, one can establish age models based on secular variations of the geomagnetic field on sediments recovered uniquely below the CCD. Comparison of paleomagnetic directions near a tephra and a paleomagnetic direction of contemporaneous pyroclastic flow deposits acquired by different magnetization processes shows precise depositional ages reflecting the magnetization delay of the marine sediment record.

AbstractWe present an advance toward accurately predicting the arrivals of coronal mass ejections (CMEs) at the terrestrial planets, including Earth. For the first time, we are able to assess a CME prediction model using data over two thirds of a solar cycle of observations with the Heliophysics System Observatory. We validate modeling results of 1337 CMEs observed with the Solar Terrestrial Relations Observatory (STEREO) heliospheric imagers (HI) (science data) from 8 years of observations by five in situ observing spacecraft. We use the self‐similar expansion model for CME fronts assuming 60° longitudinal width, constant speed, and constant propagation direction. With these assumptions we find that 23%–35% of all CMEs that were predicted to hit a certain spacecraft lead to clear in situ signatures, so that for one correct prediction, two to three false alarms would have been issued. In addition, we find that the prediction accuracy does not degrade with the HI longitudinal separation from Earth. Predicted arrival times are on average within 2.6 ± 16.6 h difference of the in situ arrival time, similar to analytical and numerical modeling, and a true skill statistic of 0.21. We also discuss various factors that may improve the accuracy of space weather forecasting using wide‐angle heliospheric imager observations. These results form a first‐order approximated baseline of the prediction accuracy that is possible with HI and other methods used for data by an operational space weather mission at the Sun‐Earth L5 point.
Climatology of seasonal snowfall accumulation across the Sierra Nevada (USA): Accumulation rates, distributions, and variability
Authors: Huning Laurie S. , Margulis Steven A. 
Published: July 2017

AbstractA detailed picture of how snowfall varies across high‐elevation mountain ranges in both space and time remains a knowledge gap in understanding the montane hydrologic cycle. Previous studies generally used point‐scale snow measurements in an attempt to represent the spatial variability of snowfall across a range; however, these traditional approaches provide incomplete insight into the cumulative snowfall (CS) distribution from the basin‐scale to the mountain range‐scale. In this study, a high‐resolution, spatially distributed snow reanalysis was utilized to characterize 31 winters (water years 1985–2015) of snowfall distributions, snowfall accumulation rates, and snowstorms across the Sierra Nevada (USA). The CS data set (quantified in units of snow water equivalent) was verified against over 2600 station years of in situ observations. The seasonal CS was found to have mean and root‐mean‐squared differences of −4 and 12 cm, respectively, and a correlation of 0.96 with snow pillow observations. Using this novel CS information, results indicated that the CS accumulates rapidly across all 20 basins examined with, on average, at least 50% of the integrated CS accumulating in less than or equal to 6 days or three snowstorms over each basin. The largest (or leading) snowstorms each season yield ∼27% of the CS, on average, and most frequently last 4 days. Across the range, over 40% of the leading snowstorms occur in February. This study showed that the hydroclimatology of the Sierra Nevada is driven by hydrological extremes as manifested in the high interannual variability of its seasonally integrated CS, 4.4–41.3 km3, during the 31 years.
The dynamics of hepcidin‐ferroportin internalization and consequences of a novel ferroportin disease mutation

Published: July 2017

AbstractThe hepcidin‐ferroportin axis underlies the pathophysiology of many iron‐associated disorders and is a key target for the development of therapeutics for treating iron‐associated disorders. The aims of this study were to investigate the dynamics of hepcidin‐mediated ferroportin internalization and the consequences of a novel disease‐causing mutation on ferroportin function. Specific reagents for ferroportin are limited; we developed and characterized antibodies against the largest extracellular loop of ferroportin and developed a novel cell‐based assay for studying hepcidin‐ferroportin function. We show that hepcidin‐mediated ferroportin internalization is a rapid process and could be induced using low concentrations of hepcidin. Targeted next‐generation sequencing utilizing an iron metabolism gene panel developed in our group identified a novel ferroportin p.D84E variant in a patient with iron overload. Wild‐type and mutant ferroportin constructs were generated, transfected into HEK293 cells and analysed using an all‐in‐one flow‐cytometry‐based assay to study the effects on hepcidin‐mediated internalization and iron transport. Consistent with the classical phenotype of ferroportin disease, the p.D84E mutation results in an inability to transport iron and hepcidin insensitivity. These results validate a recently proposed 3D‐structural model of ferroportin and highlight the significance of this variant in the structure and function of ferroportin. Our novel ferroportin antibody and assay will be valuable tools for investigating the regulation of hepcidin/ferroportin function and the development of novel approaches for the therapeutic modulation of iron homeostasis.
A Base‐Mediated 6‐exo‐trig versus 6‐exo‐dig Carbocyclization Strategy for the Synthesis of Functionalized Biaryl Compounds
Authors: Yadav Pratik , Shaw Ranjay , Panwar Rahul , Sahu Satya Narayan , Kumar Abhinav , Pratap Ramendra 
Published: July 2017

AbstractA base‐mediated carbocyclization study has been performed between two allowed Baldwin cyclization modes (6‐exo‐trig and 6‐exo‐dig) and it was found that 6‐exo‐trig cyclization was preferred over 6‐exo‐dig. Allyl cyanide was found to be suitable and efficient pronucleophile for this investigation and two sp2–sp2 transition‐metal‐free C−C bond formations took place in a single operation to yield two differently functionalized biaryl compounds.
Speech‐like orofacial oscillations in stump‐tailed macaque (Macaca arctoides) facial and vocal signals

Published: July 2017

AbstractObjectivesSpeech is unique to humans and characterized by facial actions of ∼5 Hz oscillations of lip, mouth or jaw movements. Lip‐smacking, a facial display of primates characterized by oscillatory actions involving the vertical opening and closing of the jaw and lips, exhibits stable 5‐Hz oscillation patterns, matching that of speech, suggesting that lip‐smacking is a precursor of speech. We tested if facial or vocal actions exhibiting the same rate of oscillation are found in wide forms of facial or vocal displays in various social contexts, exhibiting diversity among species.Materials and MethodsWe observed facial and vocal actions of wild stump‐tailed macaques (Macaca arctoides), and selected video clips including facial displays (teeth chattering; TC), panting calls, and feeding. Ten open‐to‐open mouth durations during TC and feeding and five amplitude peak‐to‐peak durations in panting were analyzed.ResultsFacial display (TC) and vocalization (panting) oscillated within 5.74 ± 1.19 and 6.71 ± 2.91 Hz, respectively, similar to the reported lip‐smacking of long‐tailed macaques and the speech of humans.DiscussionThese results indicated a common mechanism for the central pattern generator underlying orofacial movements, which would evolve to speech. Similar oscillations in panting, which evolved from different muscular control than the orofacial action, suggested the sensory foundations for perceptual saliency particular to 5‐Hz rhythms in macaques. This supports the pre‐adaptation hypothesis of speech evolution, which states a central pattern generator for 5‐Hz facial oscillation and perceptual background tuned to 5‐Hz actions existed in common ancestors of macaques and humans, before the emergence of speech.

Published: July 2017

CaseIn rare cases, spinal epidural abscess involves the entire spine and can lead to neurological deficits and sepsis if treatment is delayed or suboptimal. A 65‐year‐old man was admitted with a diagnosis of bacterial meningitis. After admission, magnetic resonance imaging showed a spinal epidural abscess from the cervical to lumbar spine. Blood culture revealed Staphylococcus aureus. The patient was initially treated medically because he had no neurological deficits. Repeat blood culture remained positive and abscesses were found in the mediastinum and bilateral psoas muscles.OutcomeSurgery was carried out and the patient's postoperative course was satisfactory.ConclusionSpinal epidural abscess can extensively affect the spine and may present with the symptoms of bacterial meningitis. It is essential to examine the entire spine and paraspinal regions and to treat early in cases of spinal epidural abscess.
