Les pirogues monoxyles du moyen âge
Authors: Laurent Fabrice
Published: January 2018

Les deux pirogues monoxyles sont datées pour l'une (Ep. 6) de la fin du XIe-tout début du XIIe siècle et pour l'autre (Ep. 14) des années 1200. L'épave Ep. 6, très partiellement préservée sur 3,35 m de long (extrémité avant en levée), est celle d'une grande pirogue monoxyle, à fond plat peu développé et bouchain en forme. Cette extrémité de la pirogue comporte un renfort transversal réservé dans la masse qui est doté d'une mortaise interprétée comme une éventuelle mortaise d'emplanture de mât de halage. L'épave Ep. 14, bien conservée sur 8,26 m de long, a une section transversale à fond plat et flancs rectilignes. Les plus notables de ses caractéristiques sont des membrures de deux types -réservées et rapportées -, des réparations par des pièces rapportées et intégrées dans la masse, des trous de jauge d'épaisseur. Pour un poids à lège de la coque de 200 kg, la capacité maximum de charge a été évaluée à 400 kg.
Les épaves modernes (XVIe-XVIIIe siècles)

Published: January 2018

In total six wrecks of boats with aquarium-container have been discovered. This is a very rarely attested archaeological ensemble. The function of these wrecks dating to the first half of the 16th century is characterised by the existence of a compartment pierced with numerous holes that served as a keep-net to hold live fish. This compartment is separated from the rest of the hull by water-tight walls. Five of these keep-net craft (wrecks Ep. 10, 11, 12, 15, 16) are simple log boats, the two others (Ep. 9 and Ep. 3) are of a plank built structure. The keep-net pirogues exhibit a general morphology characterised by a rectangular transversal section (flat bottom, straight flanks) and a longitudinal profile of a flat bottom and two swim bows. The numerous repairs might correspond, for several of the log boats (Ep. 11, 12, 15), to a re-use after adaptation. One of the two keep-net craft with a plank assembled hull (Ep. 13) appears also to have been re-used and transformed into a " bachuel The study of the overall dimensions and details of elements of the hull (spacing of the frames, height of the planking, width etc) would tend to show the application of the "Lyonnais" foot by the carpenters of the keep-net boats. The study closes by placing these craft within a historical perspective as part of the development of a régional market.

Dating from 1746, the wreck Ep. 1 is preserved to a length of 12.24 metres. Only one of its extremities is destroyed. The hull, plank assembled, is "bottom based". The bottom is of conifer wood strakes, the "chine strakes" of oak and the swim bow, stili preserved, is oak. The bowed bottom strakes are assembled by dowelling to the fìat fìoor frames ("épars"), which are, except for one coniferous frame, of oak. The floor-timbers are associated with paired L shaped frames of oak dowelled and, here and there, nailed to the side planks. The seams are made water-tight by strips of moss covered by batons and held in place by metal staples. This hull displays a certain number of particular features : "transverse girders, longitudinal girders, scarfing of the bottom planks, scarfing of the girders". The reconstituted dimensions would be : length 12.33 metres ; width at bottom 2.60 metres ; width at planking 3.369 metres. The metrological study has demonstrated that the foot and the French toise de Roi measurement were probably used in the shipyard where this boat was constructed. Its morphology might correspond to that of a "penelle" of the upper Rhône and Saône Rivers.
Le dossier de l'épave du Golo (Mariana, Haute-Corse). Nouvelles considérations sur l'interprétation et l'origine de l'épave
Authors: Pomey Patrice
Published: January 2018

Découverte et documentée au XVIIIe siècle, publiée à la fin du XIXe par l'amiral F.-E. Paris, dans ses Souvenirs de marine conservés, l'épave du Colo est originale à bien des égards. Son état de conservation semble exceptionnel et ses caractéristiques techniques très particulières posent, en l'absence de tout contexte, le problème de son origine et de sa datation.

L'étude du dossier de l'épave, conservé au Musée national de la Marine à Paris, apporte à cet égard de nombreux éléments nouveaux. Il comporte, en effet, divers plans et relevés annotés de la main de l'amiral Paris ainsi qu'une note manuscrite inédite riche d'informations. L'étude de ces documents permet de montrer que les plans publiés dans les Souvenirs de marine conservés sont en fait largement restitués et conduit à mieux préciser l'état original de l'épave.

Dès lors, l'étude de l'épave s'en trouve modifiée et il devient possible d'en proposer une nouvelle restitution fondée sur un assemblage par tenons et mortaises du bordé, selon un schéma encore archaïsant, et un assemblage par ligatures des membrures. L'ensemble inscrit manifestement l'épave du Colo dans la tradition archaïque. La comparaison avec les épaves de tradition ibérique d'influence punique de Mazarrón et de Binissafùller, d'une part, et avec les épaves grecques archaïques de la famille Jules-Verne 7 et 9, d'autre part, conduit à rattacher l'épave du Golo à la tradition ibérique d'influence punique aux alentours des VIIe-VIe siècle avant J.-C.

Hélène Bernard, Marie-Pierre Jézégou, Philippe Blanc, Benoit Mille, The shipwreck Riches Dunes 5 at Marseillan (Hérault) : a transporter of decorative objects for domestic use in the 2nd century AD.

The Riches Dunes 5 site is located at a depth of some 6 métrés to the east of Marseillan-Plage (Hérault). Several vestiges suggest the hypothesis of a shipwreck. The cargo material consists of a 3 tonne block of marble and différent decorative elements in marble. Analyses have revealed différent provenances and the prépondérant mass of the marble is from eastern provinces of the Empire, with only some from the quarries of Luni. In addition there is a small ibis head in lead. The features of the large block might suggest that it was ordered for use as a stele. The other pieces of marble could be an order of "second hand" elements for private décoration based upon reused pieces having been dismantled from their original décor.

The palaeo-environmental context.

The Arles-Rhône 3 wreck, once set within its archaeological, geomorphological and sedimentological context, can lead to a proposed morphology of the Rhône channel that crossed Arles around the 1st century AD. The heavy works and banking of the channel played a probable role in the changing of hydraulic conditions that contributed to a contraction of the channel and improvement of its functioning. According to the stratigraphic data, the sinking occurred during a hydrological event of great intensity whose terminus post quem, as revealed by sedimentary sequence dating, is set at 66 AD.
La navigation du chaland
Authors: Marlier Sabrina
Published: January 2018

Pour descendre le fleuve, le chaland se laissait porter par le courant. Des rames d’appoint pouvaient néanmoins être utilisées soit pour accélérer la descente soit pour assurer la manoeuvre dans les courants. Si les eaux du fleuve étaient basses, des perches de sondes pouvaient être utilisées. Pour la remonte, en revanche, il fallait vaincre le fort courant du fleuve et surmonter les obstacles qui se présentaient. La remontée du fleuve s’effectuait par halage. Jusqu’à la fi n du XVe s, le halage sur le Rhône était assuré par des hommes («halage au col » ). Pour l’Antiquité, on ne dispose que de peu de documents sur le halage ; il s’agit de témoignages textuels (Martial, Ausone et Sidoine Apollinaire) et iconographiques (bas-reliefs de Cabrières-d’Aigues, de Colonzelle, d’Igel, de Neumagen, et sur la statue représentant Le Tibre) en relation avec le bassin rhodanien (Rhône, Saône et Durance), la Moselle et le Tibre. En termes de puissance, ce sont les documents du Moyen Âge qui renseignent le rapport de un haleur pour 1,5 tonne de charge utile. Ainsi, pour le chaland Arles-Rhône 3 chargé au maximum de ses capacités, une vingtaine de haleurs étaient nécessaires.
La fonction du Chaland

The function of the barge.

The function of the Arles-Rhône 3 barge was that of a river transport unit. The last load transported by this boat shows that it carried heavy material destined for Arles (for development of embankments, building of public monuments or a house) or else for the Camargue (construction of a villa, farm, roads, embankments etc.). The detachable and adjustable nature of the hold designed to receive the load of stones leads to the notion that other types of cargo could also have been transported on this barge.
Conclusion

Published: January 2018

Au terme de la réflexion sur l’interprétation historique de l’épave du chaland Arles-Rhône 3, il apparaît manifeste que c’est dans une perspective de grande diversité architecturale qu’il faut replacer cette épave qui, au sein de la tradition « Rhône-Saône » , ne représente ainsi qu’une «famille architecturale » , plus particulière au Bas-Rhône et à «l’espace nautique arlésien » , à côté d’autres familles plus propres aux espaces nautiques d’amont comme la famille constituée par les épaves des chalands du Parc Saint-Georges. Après les épaves de Lyon, l’épave Arles-Rhône 3 contribue à son tour à l’élaboration de cette «nouvelle histoire » de l’architecture nautique fluviale antique.

It has recently been discovered that some, if not all, classical novae emit GeV gamma-rays during outburst, but the mechanisms involved in the production ofgamma-rays are still not well understood. We present here a comprehensive multiwavelength data set—from radio to X-rays—for the most gamma-ray-luminous classical nova to date, V1324 Sco. Using this data set, we show that V1324 Sco is a canonical dusty Fe ii-type nova, with a maximum ejecta velocity of 2600 km s−1 and an ejecta mass of a few

. There is also evidence for complex shock interactions, including a double-peaked radio light curve which shows high brightness temperatures at early times. To explore why V1324 Sco was so gamma-ray luminous, we present a model of the nova ejecta featuring strong internal shocks and find that higher gamma-ray luminosities result from higher ejecta velocities and/or mass-loss rates. Comparison of V1324 Sco with other gamma-ray-detected novae does not show clear signatures of either, and we conclude that a larger sample of similarly well-observed novae is needed to understand the origin and variation of gamma-rays in novae.
An Alternate Approach to Measure Specific Star Formation Rates at

Published: January 2018

We trace the specific star formation rate (sSFR) of massive star-forming galaxies (

) from

to 7. Our method is substantially different from previous analyses, as it does not rely on direct estimates of star formation rate, but on the differential evolution of the galaxy stellar mass function (SMF). We show the reliability of this approach by means of semianalytical and hydrodynamical cosmological simulations. We then apply it to real data, using the SMFs derived in the COSMOS and CANDELS fields. We find that the

is proportional to

at

, in agreement with other observations but in tension with the steeper evolution predicted by simulations from

to 2. We investigate the impact of several sources of observational bias, which, however, cannot account for this discrepancy. Although the SMF of high-redshift galaxies is still affected by significant errors, we show that future large-area surveys will substantially reduce them, making our method an effective tool to probe the massive end of the main sequence of star-forming galaxies.
YSO Jets in the Galactic Plane from UWISH2. IV. Jets and Outflows in Cygnus-X
Authors: Makin S. V. , Froebrich D.
Published: January 2018

We have performed an unbiased search for outflows from young stars in Cygnus-X using 42 deg2 of data from the UKIRT Widefield Infrared Survey for H2 (UWISH2 Survey), to identify shock-excited near-IR H2 emission in the 1–0 S(1) 2.122 μm line. We uncovered 572 outflows, of which 465 are new discoveries, increasing the number of known objects by more than 430%. This large and unbiased sample allows us to statistically determine the typical properties of outflows from young stars. We found 261 bipolar outflows, and 16% of these are parsec scale. The typical bipolar outflow is 0.45 pc in length and has gaps of 0.025–0.1 pc between large knots. The median luminosity in the 1–0 S(1) line is 10−3

. The bipolar flows are typically asymmetrical, with the two lobes misaligned by 5°, one lobe 30% shorter than the other, and one lobe twice as bright as the other. Of the remaining outflows, 152 are single-sided and 159 are groups of extended, shock-excited H2 emission without identifiable driving sources. Half of all driving sources have sufficient WISE data to determine their evolutionary status as either protostars (80%) or classical T Tauri stars (20%). One-fifth of the driving sources are variable by more than 0.5 mag in the K-band continuum over several years. Several of the newly identified outflows provide excellent targets for follow-up studies. We particularly encourage the study of the outflows and young stars identified in a bright-rimmed cloud near IRAS 20294+4255, which seems to represent a textbook example of triggered star formation.

NASA’s New Horizons spacecraft’s voyage through the Pluto system centered on 2015 July 14 provided images of Pluto’s small satellites Nix and Hydra at viewing angles unattainable from Earth. Here, we present solar phase curves of the two largest of Pluto’s small moons, Nix and Hydra, observed by the New Horizons LOng Range Reconnaissance Imager and Multi-spectral Visible Imaging Camera, which reveal the scattering properties of their icy surfaces in visible light. Construction of these solar phase curves enables comparisons between the photometric properties of Pluto’s small moons and those of other icy satellites in the outer solar system. Nix and Hydra have higher visible albedos than those of other resonant Kuiper Belt objects and irregular satellites of the giant planets, but not as high as small satellites of Saturn interior to Titan. Both Nix and Hydra appear to scatter visible light preferentially in the forward direction, unlike most icy satellites in the outer solar system, which are typically backscattering.
End-of-Life Conversations as a Legacy
Authors: Sorrell Jeanne M.
Published: January 2018

Advance directives such as living wills and health care powers of attorney are important documents that offer patients ways to avoid unwanted care when they are unable to express their wishes. Although health care professionals have increased focus on advance care planning in recent years, approximately two thirds of American adults do not have advance medical directives. In addition, 90% of individuals believe that talking to loved ones about end-of-life wishes is important, but only 27% have done so. It is important for nurses to understand the complex factors that influence how individuals make health care decisions and identify ways to encourage conversations with family, friends, and health care providers to help clarify patients' wishes for endof-life care.

An exploratory factor analysis on the Eating Disorder Examination-Questionnaire (EDE-Q) is presented for a clinical sample of women with anorexia nervosa. THE EDE-Q was completed by 169 participants after admission to an inpatient unit for eating disorders. Results of the current study did not support the four-factor model presented by the EDE-Q. A new four-factor solution was obtained with two factors showing similarity to the Restraint and Eating Concern subscales of the original model. The Shape and Weight Concern items primarily loaded together on one factor, along with preoccupation with food and fear of losing control over eating, two Eating Concern items. Finally, an appearance factor was obtained that supports the results of prior research. [

Published: January 2018

By methods of optical, scanning and transmission electron diffraction microscopy and microhardness and tribology parameters measurement the changes regularities of structure-phase states, defect substructure of rails surface after the long term operation (passed tonnage of gross weight 500 and 1000 mln. tons) were established. It is shown that the wear rate increases in 3 and 3.4 times after passed tonnage of gross weight 500 and 1000 mln. tons, accordingly, and the friction coefficient decreases in 1.4 and 1.1 times. The cementite plates are destroying absolutely and cementite particles of around form with the sizes 10-50 nm are forming after passed tonnage 500 mln tons. The appearance of dynamical recrystallization initial stages is marked after the passed tonnage 1000 mln tons. It is shown that the operation of steel rails is accompanied by full fractures in surface layers with lamellar pearlite grains and the formation of ferrite–carbide mixtures with nanosized particles. The deformation of steel increases the densities of scalar and excess dislocations, the curvature–torsion values of the crystal lattice, and the amplitudes of internal stress fields. The possible mechanisms of established regularities are discussed. It is noted that two competitive processes can take place during rails long term operation: 1. Process of cutting of cementite particles followed by their carrying out into the volume of ferrite grains or plates (in the structure of pearlite). 2. Process of cutting, the subsequent dissolution of cementite particles, transition of carbon atoms to dislocations (into Cottrell atmospheres), transition of carbon atoms by dislocations into volume of ferrite grains or plates followed by repeat formation of nanosize cementite particles.

Published: January 2018

The structural-phase state of weld joints of the samples of Grade 2 alloys with micro- and submicrocrystalline structure is studied using methods of X-ray diffraction analysis. The weld joint was obtained by joining plates with a thickness of 2 mm using the electron-beam welding method. It is established that the transfer of the titanium alloy Grade 2 from the microcrystalline state into the submicrocrystalline state during the process of gradual grinding of grains in the samples by the abc-pressing method at a parallel stepwise decrease of the temperature in the range of 750-500 °C leads to an intensive introduction of oxygen atoms into the crystalline lattice of the solid solution a-Ti. The presence of an increased content of oxygen atoms in the crystalline lattice of the solid solution a-Ti in the submicrocrystalline state in the Grade 2 alloy in the weld zone and in the heat-affected zone promotes the formation of metastable phases w-Ti and α''-Ti. The obtained results made it possible to assume that in the process of electron-beam welding in the Grade 2 alloy in the submicrocrystalline state, an increased concentration of interstitial oxygen atoms in the crystalline lattice of the solid solution based on a–Ti plays a significant role in the formation of a wide range of structural-phase states in the weld zone and in the heat-affected zone.

In the context of inflammation, osteopontin (Opn) is known to promote effector responses, facilitating a proinflammatory environment; however, its role during antigenic tolerance induction is unknown. Using a mouse model of asthma, we investigated the role of Opn during antigenic tolerance induction and its effects on associated regulatory cellular populations prior to disease initiation. Our experiments demonstrate that Opn drives protective antigenic tolerance by inducing accumulation of IFN-β–producing plasmacytoid dendritic cells, as well as regulatory T cells, in mediastinal lymph nodes. We also show that, in the absence of TLR triggers, recombinant Opn, and particularly its SLAYGLR motif, directly induces IFN-β expression in Ag-primed plasmacytoid dendritic cells, which renders them extra protective against induction of allergic airway disease upon transfer into recipient mice. Lastly, we show that blockade of type I IFNR prevents antigenic tolerance induction against experimental allergic asthma. Overall, we unveil a new role for Opn in setting up a tolerogenic milieu boosting antigenic tolerance induction, thus leading to prevention of allergic airway inflammation. Our results provide insight for the future design of immunotherapies against allergic asthma.
Road traffic collisions in Malawi: Trends and patterns of mortality on scene
Authors: Schlottmann Francisco , Tyson Anna F. , Cairns Bruce A. , Varela Carlos , Charles Anthony G.
Published: January 2018

Background: Worldwide, 90% of injury deaths occur in low- and middle-income countries (LMIC). Road traffic collisions (RTCs) are increasingly common and result in more death and disability in the developing world than in the developed world. We aimed to examine the prehospital case fatality rate from RTCs in Malawi.Material and Methods: A retrospective study was performed utilizing the Malawian National Road Safety Council (NRSC) registry from 2008-2012. The NRSC data were collected at the scene by police officers. Victim, vehicle, and environmental factors were used to describe the characteristics of fatal collisions. Case fatality rate was defined as the number of fatalities divided by the number of people involved in RTCs each year. Logistic regression analysis was used to determine predictors of crash scene fatality.Results: A total of 11,467 RTCs were reported by the NRSC between 2008 and 2012. Of these, 34% involved at least one fatality at the scene. The average age of fatalities was 32 years and 82% were male. Drivers of motor vehicles had the lowest odds of mortality following RTCs. Compared to drivers; pedestrians had the highest odds of mortality (OR 39, 95% CI 34, 45) followed by bicyclists (OR 26, 95% CI 22, 31). The average case fatality rate was 17% / year, and showed an increased throughout the study period.Conclusions: RTCs are a common cause of injury in Malawi. Approximately one-third of RTCs involved at least one death at the scene. Pedestrians were particularly vulnerable, exhibiting very high odds of mortality when involved in a road traffic collision. We encourage the use of these data to develop strategies in LMIC countries to protect pedestrians and other road users from RTCs.
A Steady State Continuous Flow Chamber for the Study of Daytime and Night time Chemistry under Atmospherically Relevant NO levels

Published: January 2018

Abstract. Experiments performed in laboratory chambers have contributed significantly to the understanding of the fundamental kinetics and mechanisms of the chemical reactions occurring in the atmosphere. Two chemical regimes, classified as high-NO versus zero-NO conditions, have been extensively studied in previous chamber experiments. Results derived from these two chemical scenarios are widely parameterized in chemical transport models to represent key atmospheric processes in urban and pristine environments. As the anthropogenic NOx emissions in the United States have decreased remarkably in the past few decades, the classic high-NO and zero-NO conditions are no longer applicable to many regions that are constantly impacted by both polluted and background air masses. We present here the development and characterization of the NCAR Atmospheric Simulation Chamber, which is operated in steady state continuous flow mode for the study of atmospheric chemistry under intermediate NO conditions. This particular chemical regime is characterized by constant sub-ppb levels of NO and can be created in the chamber by precise control of the inflow NO concentration and the ratio of chamber mixing to residence timescales. Over the range of conditions achievable in the chamber, the lifetime of peroxy radicals (RO2), a key intermediate from the atmospheric degradation of volatile organic compounds (VOCs), can be extended to several minutes, and a diverse array of reaction pathways, including unimolecular pathways and bimolecular reactions with NO and HO2, can thus be explored. Characterization experiments under photolytic and dark conditions were performed and, in conjunction with model predictions, provide a basis for interpretation of prevailing atmospheric processes in environments with intertwined biogenic and anthropogenic activities. We demonstrate the proof of concept of the steady state continuous flow chamber operation through measurements of major first-generation products, methacrolein (MACR) and methyl vinyl ketone (MVK), from OH- and NO3-initiated oxidation of isoprene.
Interaction between elevated CO2 and phytoplankton-derived organic matter under solar radiation on bacterial metabolism from coastal waters

Published: January 2018

Abstract. Microcosm experiments to assess bacterioplankton response to phytoplankton-derived organic matter obtained under current and future-ocean CO2 levels were performed. Surface seawater enriched with inorganic nutrients was bubbled for 8 days with air (current CO2 scenario) or with a 1000 ppm CO2–air mixture (future CO2 scenario) under solar radiation. The organic matter produced under the current and future CO2 scenarios was subsequently used as inoculum. Triplicate 12 L flasks filled with 1.2 µm-filtered natural seawater enriched with the organic matter inocula were incubated in the dark for 8 days under CO2 conditions simulating current and future CO2 scenarios to study the bacterial response. The acidification of the media increased bacterial respiration at the beginning of the experiment while the addition of the organic matter produced under future levels of CO2 was related to changes in bacterial production and abundance. The balance between both, respiration and production, made that the bacteria grown under future CO2 levels with an addition of non-acidified matter showed the best growth efficiency at the end of the incubation. However cells grown under future scenarios with high CO2 levels and acidified organic matter additions did not perform differently than those grown under present CO2 conditions, independently of the addition of acidified or non-acidified organic matter. This study demonstrates that the increase in atmospheric CO2 concentrations can affect bacterioplankton directly by changes in the respiration rate and indirectly by changes on the organic matter with concomitant effects on bacterial production and abundance.
Development of a precipitation–area curve for warning criteria of short-duration flash flood
Authors: Bae Deg-Hyo , Lee Moon-Hwan , Moon Sung-Keun
Published: January 2018

Abstract. This paper presents quantitative criteria for flash flood warning that can be used to rapidly assess flash flood occurrence based on only rainfall estimates. This study was conducted for 200 small mountainous sub-catchments of the Han River basin in South Korea because South Korea has recently suffered many flash flood events. The quantitative criteria are calculated based on flash flood guidance (FFG), which is defined as the depth of rainfall of a given duration required to cause frequent flooding (1–2-year return period) at the outlet of a small stream basin and is estimated using threshold runoff (TR) and antecedent soil moisture conditions in all sub-basins. The soil moisture conditions were estimated during the flooding season, i.e., July, August and September, over 7 years (2002–2009) using the Sejong University Rainfall Runoff (SURR) model. A ROC (receiver operating characteristic) analysis was used to obtain optimum rainfall values and a generalized precipitation–area (P–A) curve was developed for flash flood warning thresholds. The threshold function was derived as a P–A curve because the precipitation threshold with a short duration is more closely related to basin area than any other variables. For a brief description of the P–A curve, generalized thresholds for flash flood warnings can be suggested for rainfall rates of 42, 32 and 20 mm h−1 in sub-basins with areas of 22–40, 40–100 and > 100 km2, respectively. The proposed P–A curve was validated based on observed flash flood events in different sub-basins. Flash flood occurrences were captured for 9 out of 12 events. This result can be used instead of FFG to identify brief flash flood (less than 1 h), and it can provide warning information to decision-makers or citizens that is relatively simple, clear and immediate.

A new hat for librarians: providing REDCap support to establish the library as a central data hub
Authors: Read Kevin , LaPolla Fred Willie Zametkin
Published: January 2018

Background: REDCap, an electronic data capture tool, supports good research data management, but many researchers lack familiarity with the tool. While a REDCap administrator provided technical support and a clinical data management support unit provided study design support, a service gap existed.Case Presentation: Librarians with REDCap expertise sought to increase and improve usage through outreach, workshops, and consultations. In collaboration with a REDCap administrator and the director of the clinical data management support unit, the role of the library was established in providing REDCap training and consultations. REDCap trainings were offered to the medical center during the library’s quarterly data series, which served as a springboard for offering tailored REDCap support to researchers and research groups.Conclusions: Providing REDCap support has proved to be an effective way to associate the library with data-related activities in an academic medical center and identify new opportunities for offering data services in the library. By offering REDCap services, the library established strong partnerships with the Information Technology Department, Clinical Data Support Department, and Compliance Office by filling in training gaps, while simultaneously referring users back to these departments when additional expertise was required. These new partnerships continue to grow and serve to position the library as a central data hub in the institution.

Objective: This article describes the collection and analysis of annotated bibliographies created by first-year health sciences students to support their final poster projects. The authors examined the students’ abilities to select relevant and authoritative sources, summarize the content of those sources, and correctly cite those sources.Methods: We collected images of 1,253 posters, of which 120 were sampled for analysis, and scored the posters using a 4-point rubric to evaluate students’ information literacy skills.Results: We found that 52% of students were proficient at selecting relevant sources that directly contributed to the theme, topic, or debate presented in their final poster projects, and 64% of students did well with selecting authoritative peer-reviewed scholarly sources related to their topic. However, 45% of students showed difficulty in correctly applying American Psychological Association (APA) citation style.Conclusion: Our findings demonstrate a need for instructors and librarians to provide strategies for reading and comprehending scholarly articles in addition to properly using APA citation style.
Análisis crítico de la fiscalidad de las cooperativas de segundo grado como fórmula de integración
Authors: Aguilar Rubio Marina
Published: January 2018

Las sociedades cooperativas de segundo grado constituyen uno de los instrumentos básicos de concentración empresarial previstos en la legislación cooperativa y ha sido la fórmula tradicionalmente utilizada por las cooperativas a la hora de acometer un proyecto de integración.El trabajo que se presenta trata de mostrar la especial tributación de las sociedades cooperativas de segundo grado, que nos interesan especialmente por ser el instrumento de integración más utilizado en España por las sociedades cooperativas para emprender procesos de concentración en el ámbito agrario, sector clave en nuestro entorno geográfico.Centraremos el estudio de su fiscalidad en el Impuesto sobre Sociedades por las particularidades tributarias que presenta el mismo en este tipo societario. Las sociedades cooperativas de segundo grado pueden optar por tributar como simples sociedades cooperativas, según lo regulado en la Ley 20/1990, de 19 de diciembre, sobre Régimen Fiscal de Cooperativas, o hacerlo como grupo cooperativo, acogiéndose en el régimen especial de tributación consolidada establecido para este tipo social.Al igual que las sociedades de primer grado éstas disfrutan de una serie de beneficios fiscales tanto en la imposición directa como en la indirecta, como consecuencia de la naturaleza social de las mismas.

Minería de datos, una innovación de los métodos cuantitativos de investigación, en la medición del rendimiento académico universitario
Authors: Dicovskiy Riobóo Luis María , Pedroza Manuel Enrique
Published: January 2018

En este ensayo sobre calidad universitaria y su medición, se hace una revisión teórica sobre los factores que inciden en el rendimiento académico. En la revisión teórica, se encontró que hay consenso que las mayores deserciones ocurren en el primer año de la universidad y que estas causas están también vinculadas a la historia preuniversitaria del estudiante. La asistencia a clases de forma regular y la motivación a su carrera, también son aspectos importantes que resaltan para mejorar el rendimiento académico. El factor género: varón o mujer, es un aspecto que se debe considerar en cualquier estudio de rendimiento académico. Se discute que las bases de datos académicas que están en los centros universitarios, son un material importante en cualquier investigación académica, y que deberían ser estudiadas por minería de datos, como un método innovador dentro los métodos tradicionales de investigación cuantitativa. La minería de datos permite extraer nuevos conocimientos, a partir de base de datos que surgen de la acumulación de información académica en el tiempo.
A presença feminina em fotoclubes no século XX: apontamentos preliminares
Authors: Grecco Priscila Miraz de Freitas
Published: January 2018

No presente artigo abordamos a presença de fotógrafas amadoras atuantes no Foto Cine Clube Bandeirante durante as décadas de 1940 e 1950. Com o intuito de pensarmos como seu deu a atuação de mulheres em um ambiente majoritariamente masculino como fotoclubes, apontamos a participação de algumas fotógrafas que aparecem no Boletim Foto Clube, órgão de difusão mensal das ideias e imagens produzidas pelo Foto Cine Clube Bandeirante durante as décadas de 1940 e 1950, momento em que o clube congregava a produção do que ficou conhecido como Escola Paulista de Fotografia. Acreditamos que o interesse crescente por essa temática no Brasil em geral, e não somente em São Paulo, aos poucos possa delinear um perfil mais definido sobre quem eram essas mulheres.

Published: January 2018

Sentiment analysis has become one of the most popular process to predict stock market behaviour based on consumer reactions. Concurrently, the availability of data from Twitter has also attracted researchers towards this research area. Most of the models related to sentiment analysis are still suffering from inaccuracies. The low accuracy in classification has a direct effect on the reliability of stock market indicators. The study primarily focuses on the analysis of the Twitter dataset. Moreover, an improved model is proposed in this study; it is designed to enhance the classification accuracy. The first phase of this model is data collection, and the second involves the filtration and transformation, which are conducted to get only relevant data. The most crucial phase is labelling, in which polarity of data is determined and negative, positive or neutral values are assigned to people opinion. The fourth phase is the classification phase in which suitable patterns of the stock market are identified by hybridizing Naïve Bayes Classifiers (NBCs), and the final phase is the performance and evaluation. This study proposes Hybrid Naïve Bayes Classifiers (HNBCs) as a machine learning method for stock market classification. The outcome is instrumental for investors, companies, and researchers whereby it will enable them to formulate their plans according to the sentiments of people. The proposed method has produced a significant result; it has achieved accuracy equals 90.38%.

The Senegal River basin (Guinea, Mali, Mauritania, and Senegal) is a key agricultural production area in sub-Saharan Africa. Here, rice fields are left fallow during the cooler winter season, when the night temperatures reach 16 °C but the maximum daily temperatures remain above 30 °C. This season was used for the first time to conduct multi-environmental trials of durum wheat. Twenty-four elite breeding lines and cultivars were tested for adaptation during seasons 2014-15 and 2015-16 at two stations: Kaedi, Mauritania and Fanaye, Senegal. Phenological traits, grain yield and its components were recorded. Top grain yield was recorded at 5,330 kg ha-1 and the average yield at 2,484 kg ha-1. The season lasted just 90 days from sowing to harvest. Dissection of the yield in its components revealed that biomass and spike fertility (i.e. number of seeds produced per spike) were the most critical traits for adaptation to these warm conditions. This second trait was confirmed in a validation experiment conducted in 2016-17 at the same two sites. Genotype × environment interaction was dissected by AMMI model, and the derived IPC values used to derive an ‘AMMI wide adaptation index’ (AWAI) to asses yield stability. The use of a selection index that combined adjusted means of yield and AWAI identified three genotypes as the most stable and high yielding: ‘Bani Suef 5’, ‘DAWRyT118’, and ‘DAWRyT123’. The last two genotypes were also confirmed among the best in a validation trial conducted in season 2016-17. The data presented here are meant to introduce to the breeding community the use of these two research stations along the Senegal River for assessing heat tolerance of wheat or other winter cereals, as well as presenting two new ideal germplasm sources for heat tolerance, and the identification of spike fertility as the key trait controlling adaptation to heat stress.

Analysis of the gene action exhibited by an agronomic trait in crop plants is useful in the planning of an effective plant breeding program. This study sought to establish the inheritance variance of root yield components and beta carotene content present in sweet potato clones commonly grown in Kenya. Ten contrasting parents were selected based on their beta carotene content, dry matter content and yield potential. They were planted in pots in the green house at KEPHIS-Muguga, Kenya, where they were grafted into Ipomoea setosa to boost their ability to flower. Five parents were further selected based on their ability to flower under local environmental conditions and crossed in a 5 × 5 half diallel manner. Five parents and ten F1 clones arising from this hybridization were evaluated at KALRO-Kiboko, Kenya during two rainy seasons. The field trials were laid out in a randomized complete block design of three replications. The data were scored for root yield characteristics, beta carotene and root dry matter content. Griffing Method II, Model 1 diallel was used to estimate the general and specific combining ability. Genetic variability for beta carotene and root dry matter content indicated that the two traits were controlled mostly by both additive and dominant gene actions. Heterosis gene effects were found for beta carotene and root dry matter content which would be useful in the improvement of sweet potato productivity.

There is an increasing consumer demand for alternative cereals nowadays. Spelt wheat (Triticum aestivum ssp. Spelta) appears to be a future source for the agriculture and food sector. Alternaria spp. infections might become a serious danger to the worldwide grain industry, resulting in yield losses and reduction of end-use quality, with potential harmful effect of Alternaria toxins on human and animal health. This paper presents the first assessment of the impact of Alternaria infection and its toxins to quality of spelt wheat. The results showed that fungal contamination significantly reduced both trade and technological quality parameters. Volume weight, thousand kernel weight and wet gluten were significantly decreased, while protein content was significantly higher in Alternaria inoculated treatments. Although with slight decrease, falling number was not significantly affected by fungal contamination. The most negative impact of alternariol (AOH) was registered on volume weight and thousand kernel weight (-0.847; -0.898), while highly significant positive correlation was found between AOH and protein content (0.758). Alternaria spp. additionally destroyed spelt gluten structure, resulting in reduction of dough energy and baking quality with no significant influence of mycotoxins (AOH and AME) on technological quality parameters.
