Published: January 2018

Los estudios bibliométricos aplicados a la producción científica de las universidades aportan información valiosa para la toma de decisiones en materia de planificación y evaluación de sus actividades de investigación. El objetivo de este artículo es representar y analizar el perfil investigador de la Facultad de Ingeniería Industrial del Instituto Superior Politécnico José Antonio Echeverría (Cujae) de Cuba, a partir de un estudio bibliométrico de la producción científica de sus investigadores en las bases de datos Scopus y Web of Science (WOS) durante el periodo 2003-2012. Se evalúan indicadores validados internacionalmente para la dimensión cuantitativa y cualitativa de la producción, así como indicadores de la colaboración científica, los cuales permiten determinar la visibilidad e impacto de estas publicaciones a nivel internacional. Mediante la comparación de los resultados fue posible la valoración de la contribución de la facultad a la posición de la Cujae en las distintas ediciones del ranking iberoamericano SIR. Se concluye que, aun cuando el número de artículos refleja una tendencia creciente en los últimos años, es bajo el porcentaje de trabajos en colaboración internacional y el promedio de citas por artículos es inferior a la tendencia descrita en la literatura.AbstractThe bibliometric studies applied to the scientific production of universities can provide valuable information for the decision-making process related to research planning and evaluation. The objective of this paper is to represent and to analyze the research profile of the Industrial Engineering School of the Polytechnic University of Havana José Antonio Echeverría (Cujae) in Cuba, by means of a bibliometric study applied to its scientific production indexed in the databases Scopus and Web of Science during the period 2003-2012. There were evaluated internationally validated indicators for the quantitative and qualitative dimension of the production, as well as indicators for the scientific collaboration, which allowed the determination of the visibility and impact of these publications at international level. By means of the comparison of the results, it was possible the assessment of the contribution of the School to the position of Cujae in the several editions of the SIR Latin American ranking. It was concluded that, even though there has been a positive tendency in the number of articles in the last years, the percentage of papers in international collaboration is low and the average of cites per paper is below the tendency described in the literature.

Published: January 2018

El objetivo de este trabajo es analizar cómo un sistema de estímulos económicos y de reconocimiento a las actividades de investigación en México ha impactado la productividad científica de las instituciones de educación superior (ies) a nivel nacional. Este análisis emplea una base de datos con información de 27,667 investigadores mexicanos que han formado parte del Sistema Nacional de Investigadores (sni), al menos por un año, en el periodo 1991-2011, e integra 122,406 artículos publicados por dichos científicos en revistas isi. A fin de determinar la cantidad y calidad de la productividad de las ies, se consideraron como unidades de medida los artículos de publicaciones científicas y las citas bibliográficas. Los resultados indican que únicamente el 28% de las ies analizadas emitieron uno o más artículos en el periodo de estudio. Adicionalmente, nuestros resultados muestran que en diez universidades se agrupa tanto la mayor cantidad de artículos publicados, como la mayor cantidad de citas bibliográficas. Por otra parte, se muestra que la edad máxima de productividad es a los 58 años para el caso de las investigadoras y 57 años para los investigadores. Finalmente, una de las contribuciones de este trabajo es que muestra que las actividades de colaboración están en continuo crecimiento entre los investigadores.

Nowadays, there are biologically sustainable options that can partially replace synthetic fertilizers and reduce production costs. To test the response of 18 maize varieties to synthetic fertilization (FQ), synthetic fertilization plus inoculant (FQB) and synthetic fertilization plus compost (FQC), in 2010 two experiments were established in rainfed conditions in the Valley of Puebla, with a completely randomized design, under a split plots arrangement, with three replications. Type of fertilization was assigned to the main plot and maize genotypes were the split plot. No differences were found in grain and stover yield by type of fertilization. There was a strong interaction between varieties and type of fertilizer as well as between varieties and location in grain and stover yield. For the interaction between variety and type of fertilization, it was found that 56% of the varieties showed higher yields with FQC, in while 27.8% had higher yields with FQB and 16.7% yielded better with FQ. The highest stover yield was obtained in San Andrés Calpan with FQC (8.8 Mg ha-1), while in San Pedro Tlaltenango it was obtained with FQB (15.3 Mg ha‑1) and FQ (15.4 Mg ha‑1). The use of both synthetic fertilization and inoculant or compost maintains and increases maize grain and stover yield, compared with using only synthetic fertilizer.
MULTITEMPORAL LANDSAT DATA TO QUICK MAPPING OF PADDY FIELD BASED ON STATISTICAL PARAMETERS OF VEGETATION INDEX (CASE STUDY: TANGGAMUS, LAMPUNG)
Authors: Parsa I Made , Dirgahayu Dede 
Published: January 2018

Paddy field has unique characteristics that distinguish it from other plants. Before it planting, paddy field is always flooded so that the appearance is dominated by water (aqueous phase). Within the growth of rice, field conditions will be increasingly dominated by greenish rice plants.While at the end, the rice plants will turn yellow indicating for harvesting. During flooding stage, the normalized difference vegetation index (NDVI) of pady field is negative. The negative value of NDVI of paddy field will ultimately increase to the maximum value at the maximum vegetative growth. TheNDVI of paddy field will decrease from generative phase until harvest and after harvest. The objective of this study was to perform the vegetation index analyses for multitemporal Landsat imagery of paddy field. The results showed that the difference of vegetation index values (maximum - minimum)of paddy field were greater than the difference of vegetation index values of other land uses. Such differences values can be used as indicator to map land for rice. The evaluation results with reference data showed that the mapping accuracy (overall accuracy) was of 87.4 percent.

Currently, fishpond aquaculture becomes an interesting business for investors because of its profit, and a source of livelihood for coastal communities. Inventory and monitoring of fishpond aquaculture provide important baseline data to determine the policy of expansion and revitalization of the fishpond. The aim of this research was to conduct an inventory and monitoring of fishpond area inMaros regency of South Sulawesi province using Satellite Pour l’Observation de la Terre (SPOT -4) and Advanced Land Observing Satellite (ALOS) Phased Array type L-band Synthetic Apeture Radar (PALSAR). SPOT image classification process was performed using maximum likelihood supervised classification method and the density slice method for ALOS PALSAR. Fishpond area from SPOT data was 9693.58 hectares (ha), this results have been through the process of validation and verification by the ground truth data. The fishponds area from PALSAR was 7080.5 Ha, less than the result from SPOT data. This was due to the classification result of PALSAR data showing someobjects around fishponds (dike, mangrove, and scrub) separately and were not combined in fishponds area calculation. Meanwhile, the result of SPOT -4 image classification combined object around fishponds area.
Reading a Dead Man’s Mind: Hellenistic Philosophy, Rhetoric and Roman Law
Authors: Tellegen-Couperus Olga , Tellegen Jan Willem 
Published: January 2018

Which Hellenistic school of philosophy was most influential in the development of Roman law, Stoicism or the New Academy? Within the broader and familiar topic of the connection between philosophy, rhetoric and law in ancient Rome, an unequivocal, or at least potentially persuasive, answer to this question has so far remained elusive. While we would caution against overheated expectations of a conclusive resolution, we believe that the concept of the voluntas testatoris, whose interpretation was as much a matter of debate in Roman antiquity as it is now among Romanists, will bring us closer. Using this notion as a case study, we will argue that while the Roman jurists did not construct a balanced and general voluntas testatoris theory, they might in this area at least have been more likely to favour the New Academy approach.
‘Bulk Surveillance’, or The Elegant Technicities of Metadata
Authors: Coté Mark 
Published: January 2018

Metadata has jumped from the specialist vernacular of the archivist and programmer to public discourse in the wake of the Snowden revelations. Yet the precise nature and import of this seemingly technical artifact remains dimly understood. This chapter will undertake a cold war archaeology of metadata, from analogue information gathered by the East German Stasi to the born digital data accessed by the NSA and GCHQ. Metadata is a key cipher for the contemporary technocultural condition, and the chapter offers a case study of broader shifts in techne (the constitutive relationship between the human and technology) and in labouring practices as afforded by our data-infused digital environment. The chapter provides a concise history of metadata as highly structured data for the information discovery of data objects. Changing surveillance practices reflect the increasingly fine granularity of the digital human to the extent that now we can be considered as data objects. The degree to which this manifests an ontological shift is addressed in relation to philosophical debates about materiality and the nonhuman. It also illustrates a changing ecosystem for new kinds of informational politics. The chapter concludes by reconceptualising the persistent generation of born-digital metadata via Simondon.
Pertes du Gave d'Ossau et naissance du Neez (Vallée d'Ossau, Pyrénées-Atlantiques)
Authors: Bauer J , Oller G , Sabrier Roger 
Published: January 2018

A "gave" is a mountain torrent in the Pyrenees. The water supply of the city of Pau is depending almost entirely on a karstic spring called " Oeil du Neez" (the Neez Eye, which means spring of the Neez). L'Oeil du Neez is the main resurgence -among several others -of water sinks in the gave bed across the urgo-nian limestone ridge of Arudy. Development of this karstic system through the complex structural setting of a frontal thrust has been favoured by the geomorphic evolution of the Arudy basin, dammed to the north by a morai-nic loop, but also by the presence of highly suitable hydrodynamic and tectonic conditions (water head and fractures network).
Water quality of the Oeil du Neez is closely depending on Gave water quality. However, the catchment area proper, of this resurgence, exerts its own chemical influence.

Abstract
To obtain accurate mass measurements for cold planets discovered by microlensing, it is usually necessary to combine light curve modeling with at least two lens mass–distance relations. The physical parameters of the planetary system OGLE-2014-BLG-0124L have been constrained thanks to accurate parallax effect between ground-based and simultaneous space-based Spitzer observations. Here, we resolved the source+lens star from sub-arcsecond blends in H-band using adaptive optics (AO) observations with NIRC2 mounted on Keck II telescope. We identify additional flux, coincident with the source to within 160 mas. We estimate the potential contributions to this blended light (chance-aligned star, additional companion to the lens or to the source) and find that 85% of the NIR flux is due to the lens star at H
L = 16.63 ± 0.06 and K
L = 16.44 ± 0.06. We combined the parallax constraint and the AO constraint to derive the physical parameters of the system. The lensing system is composed of a mid-late type G main sequence star of M
L = 0.9 ± 0.05 M
⊙ located at D
L = 3.5 ± 0.2 kpc in the Galactic disk. Taking the mass ratio and projected separation from the original study leads to a planet of M
p = 0.65 ± 0.044 M
Jupiter at 3.48 ± 0.22 au. Excellent parallax measurements from simultaneous ground-space observations have been obtained on the microlensing event OGLE-2014-BLG-0124, but it is only when they are combined with ∼30 minutes of Keck II AO observations that the physical parameters of the host star are well measured.

Abstract
The optically and IR-bright and starlight-scattering HR 4796A ringlike debris disk is one of the most- (and best-) studied exoplanetary debris systems. The presence of a yet-undetected planet has been inferred (or suggested) from the narrow width and inner/outer truncation radii of its r = 1.″05 (77 au) debris ring. We present new, highly sensitive Hubble Space Telescope (HST) visible-light images of the HR 4796A circumstellar debris system and its environment over a very wide range of stellocentric angles from 0.″32 (23 au) to ≈15″ (1100 au). These very high-contrast images were obtained with the Space Telescope Imaging Spectrograph (STIS) using six-roll PSF template–subtracted coronagraphy suppressing the primary light of HR 4796A, with three image-plane occulters, and simultaneously subtracting the background light from its close angular proximity M2.5V companion. The resulting images unambiguously reveal the debris ring embedded within a much larger, morphologically complex, and biaxially asymmetric exo-ring scattering structure. These images at visible wavelengths are sensitive to and map the spatial distribution, brightness, and radial surface density of micron-size particles over 5 dex in surface brightness. These particles in the exo-ring environment may be unbound from the system and interacting with the local ISM. Herein, we present a new morphological and photometric view of the larger-than-prior-seen HR 4796A exoplanetary debris system with sensitivity to small particles at stellocentric distances an order of magnitude greater than has previously been observed.
Evidence of an Upper Bound on the Masses of Planets and Its Implications for Giant Planet Formation
Authors: Schlaufman Kevin C. 
Published: January 2018

Abstract
Celestial bodies with a mass of

have been found orbiting nearby stars. It is unknown whether these objects formed like gas-giant planets through core accretion or like stars through gravitational instability. I show that objects with

orbit metal-rich solar-type dwarf stars, a property associated with core accretion. Objects with

do not share this property. This transition is coincident with a minimum in the occurrence rate of such objects, suggesting that the maximum mass of a celestial body formed through core accretion like a planet is less than

. Consequently, objects with

orbiting solar-type dwarf stars likely formed through gravitational instability and should not be thought of as planets. Theoretical models of giant planet formation in scaled minimum-mass solar nebula Shakura–Sunyaev disks with standard parameters tuned to produce giant planets predict a maximum mass nearly an order of magnitude larger. To prevent newly formed giant planets from growing larger than

, protoplanetary disks must therefore be significantly less viscous or of lower mass than typically assumed during the runaway gas accretion stage of giant planet formation. Either effect would act to slow the Type I/II migration of planetary embryos/giant planets and promote their survival. These inferences are insensitive to the host star mass, planet formation location, or characteristic disk dissipation time.

Abstract
All known extraterrestrial dust (micrometeoroids) entering the Earth’s atmosphere is anticipated to have a significant contribution from ordinary chondritic precursors, as seen in meteorites, but this is an apparent contradiction that needs to be addressed. Ordinary chondrites represent a minor contribution to the overall meteor influx compared to carbonaceous chondrites, which are largely dominated by CI and/or CM chondrites. However, the near-Earth asteroid population presents a scenario with sufficient scope for generation of dust-sized debris from ordinary chondritic sources. The bulk chemical composition of 3255 micrometeorites (MMs) collected from Antarctica and deep-sea sediments has shown Mg/Si largely dominated by carbonaceous chondrites, and less than 10% having ordinary chondritic precursors. The chemical ablation model is combined with different initial chondritic compositions (CI, CV, L, LL, H), and the results clearly indicate that high-density (≥2.8 g cm−3) precursors, such as CV and ordinary chondrites in the size range 100–700 μm and zenith angle 0°–70°, ablate at much faster rates and lose their identity even before reaching the Earth’s surface and hence are under-represented in our collections. Moreover, their ability to survive as MMs remains grim for high-velocity micrometeoroids (>16 km s−1). The elemental ratio for CV and ordinary chondrites are also similar to each other irrespective of the difference in the initial chemical composition. In conclusion, MMs belonging to ordinary chondritic precursors’ concentrations may not be insignificant in thermosphere, as they are found on Earth’s surface.
A dataset on the species composition of amphipods (Crustacea) in a Mexican marine national park: Alacranes Reef, Yucatan
Authors: Paz-Ríos Carlos , Simões Nuno , Pech Daniel 
Published: January 2018

Alacranes Reef was declared as a National Marine Park in 1994. Since then, many efforts have been made to inventory its biodiversity. However, groups such as amphipods have been underestimated or not considered when benthic invertebrates were inventoried. Here we present a dataset that contributes to the knowledge of benthic amphipods (Crustacea, Peracarida) from the inner lagoon habitats from the Alacranes Reef National Park, the largest coral reef ecosystem in the Gulf of Mexico. The dataset contains information on records collected from 2009 to 2011. Data are available through Global Biodiversity Information Facility (GBIF).
A total of 110 amphipod species distributed in 93 nominal species and 17 generic species, belonging to 71 genera, 33 families and three suborders are presented here. This information represents the first online dataset of amphipods from the Alacranes Reef National Park. The biological material is currently deposited in the crustacean collection from the regional unit of the National Autonomous University of Mexico located at Sisal, Yucatan, Mexico (UAS-Sisal). The biological material includes 588 data records with a total abundance of 6,551 organisms. The species inventory represents, until now, the richest fauna of benthic amphipods registered from any discrete coral reef ecosystem in Mexico.

Published: January 2018

De openstelling van de markt van de top level domeinnamen in 2012 bood nieuwe perspectieven voor bedrijven, overheden en privépersonen om een geografisch component op te nemen in de domeinnaam van hun website. Sindsdien werd er weinig tot geen onderzoek verricht om de introductie van de nieuwe top level domeinnamen (TLDN) te analyseren. Op basis van het specifieke geval van de TLDN .brussels, bespreekt dit artikel het empirisch onderzoek naar de mate waarin de openstelling van de markt van de top level domeinnamen de registratiepraktijken daadwerkelijk heeft beïnvloed. Door gebruik te maken van vrij beschikbare softwaretools, zoals OpenRefine en Natural Language Processing (NLP) methodes, werd het volledige corpus van de .brussels domeinnamen (6 300) vanuit kwantitatief oogpunt geanalyseerd. Op basis van een statistisch representatieve steekproef (592 domeinnamen), maakte een kwalitatieve interpretatie een verfijndere analyse mogelijk van de manier waarop de nieuwe TLDN in de praktijk wordt gebruikt. Op die manier geeft het artikel een gedetailleerd inzicht in de gevolgen van de recente wijzigingen van de regels inzake registratie van de domeinnamen. Dankzij deze analyse kunnen onderzoekers, beleidsmakers, investeerders en al wie om de identiteit van Brussel in de digitale wereld geeft, een beter inzicht krijgen van de stand van zaken van de .brussels TLDN.
