PUBLICIDAD POLÍTICA Y LEGISLACIÓN ELECTORAL: LA COMUNICACIÓN EXTRAVIADA
Authors: Juárez Gámiz Julio 
Published: August 2018

<p>La Comunicación es materia de debate relativamente reciente en la ley electoral. Hasta antes de 1994, su tratamiento quedaba acotado al acceso de los partidos políticos a la radio y la televisión. A partir de la reforma electoral de aquel año y hasta el más reciente proceso legislativo en 2007 para modifi car la ley electoral, la discusión sobre la relación entre los medios de comunicación y los partidos políticos ha ido increscendo. Esto ha representado, entre otras cosas, un cambio sustantivo en la conceptualización del papel que la comunicación juega en los procesos electorales y, en general, en la vida democrática del país. Una conceptualización, dicho sea de paso, que hoy trasciende lo electoral.</p>
DILEMAS SOCIOBIOÉTICOS RELACIONADOS CON LA EUTANASIA
Authors: Nuñez Carpizo Elssie 
Published: August 2018

<p> El problema que plantea la práctica de la eutanasia es complejo y polémico. ¿Es siempre el ejercicio libre de la voluntad el que lleva a un individuo a solicitar que se le ayude al bien morir? ¿En qué número de casos esta petición está fundada en diversos grados de enajenación mental, a pesar de un aparente estado de equilibrio psíquico? Estas interrogantes implican una delicadísima responsabilidad del Estado, y, a juicio de la autora, se producen sólo en aquellas sociedades que conciben a la vida como un valor fundamental y no meramente instrumental.</p>

DIAGNÓSTICO DA FRAGILIDADE AMBIENTAL EMERGENTE DO MUNICÍPIO DE ANASTÁCIO, MATO GROSSO DO SUL
Authors: Wagner Leite Vanessa Aline , Perbelin Rodrigues Lidiane 
Published: August 2018

O município de Anastácio possui extensão de 2.940,6km², está situado na porção centro-oeste do estado de Mato Grosso do Sul, entre as coordenadas 20°25’00” e 21°05’00” S e 56°10’00”, 55°20’00” O. O município possui fortes ligações culturais com a região nordeste do Brasil, caracterizada pela produção artesanal de farinha de mandioca realizada pela colonia de pernambucanos do município. Apesar da culturalidade dos pequenos produtores, ocorre no município de Anastácio uma massificação da produção bovina para leite e corte, o que vem incrementando o desmatamento das áreas de Cerrado. Frente a essa problemática, o presente trabalho busca analisar a Fragilidade Ambiental Emergente do município de Anastácio-MS adaptando as metodologias de Crepani et al (2001) e Ross (1994). Foram identificadas 4 classes de fragilidade para a área de estudo: Muito baixa, Baixa, Média e Alta. Nota-se que a Fragilidade Média foi fortemente influenciada pela pastagem, o que sugere que o município sofre com o alto nível de antropização.

The experiment to obtain residue compost of rice straw (S) and tithonia (T) for reduce commercial fertilizers (CF) input and that effect for rice production. This research was arranged in Completely Randomized Block Design (RBD) with three replications of six treatments. The residue treatments are; A (input Urea 200 kg ha-1 (Ru) + SP-36 100kgha-1 (Rp)+KCl 75 kgha-1 (Rk)), B (Ru+2Rp), C (S 5 tonsha-1+ R), D ( S 5 tonsha-1+Ru+Pstarter (Ps)), E (T, 2,.5 tonsha-1 + J, 2,.5 tonsha-1 + 75%Ru+Ps), F (T, 2,.5 tonsha-1 + J, 2,5tonsha-1 +50%Ru+Ps). Data of research were statistically analysed. If the F-calculated was significantly different, they would be further analysed using LSD 0.05. The results showed that residue of T, 2,5 tonha-1 could reduce CF by 50 kg Ureaha-1 (25% R), 75 kg KCl ha-1 (100% R) and 90 kg SP-36ha-1 (90% R) with production 6,66 tonsha-1 Husk Rice (HC). If it is based on farmer tradition, residue of T could reduce CF by 50 kg Ureaha-1 (25% R), and 190 kg SP-36 ha-1 0.95.Key words : compost, residue, rice, straw, tithonia
Mass Transfer Study for Bio-Synergy in Dairy Wastewater Treatment Plant
Authors: Abdulmajeed Basma Abbas , Ibrahim Arwa Raad 
Published: August 2018

The present study addresses the behavior of gases in cultivation media as an essential factor to develop the relationship between the microorganisms that are present in the same environment. This relationship was explained via mass transfer of those gases to be a reasonable driving force in changing biological trends. Stripping and dissolution of oxygen and carbon dioxide in water and dairy wastewater were investigated in this study. Bubble column bioreactor under thermal control system was constructed and used for these processes. The experimental results showed that the removal of gases from the culture media requires more time than the dissolution. For example, the volumetric mass transfer coefficient for the removal of oxygen is 1.67 min-1 while the volumetric mass transfer coefficient for dissolution the same gas is 3.18 min-1. The same thing occurred with carbon dioxide, where the data showed that the volumetric mass transfer coefficient of the dissolution of CO2 is 0.66 min-1 while the volumetric mass transfer coefficient for removal process is 0.374 min-1. However, the two processes (dissolution and removal) with CO2 take more time than that with O2. Therefore, the production of gases due to metabolic processes in bacteria or microalgae remains in culture’s media for a certain period even if that media is sparged by air. Thus, this will give enough time for both microorganisms to consume those gases.

Performance of coated and uncoated carbide/cermet cutting tools during turning
Authors: Ulas Hasan Basri , Bilgin Musa , Sezer Huseyin Kursad , Ozkan Murat Tolga 
Published: August 2018

Abstract
Historically, cutting force and surface roughness are known to be important performance indicators in conventional machining operations and are mainly affected by material type and the choice of cutting tool. One well-known method to improve cutting tool performance is covering these tools with durable ceramic coatings to protect them from wear and thermal degradation. This work elucidates the advantage of Al2O3 and TiN coatings and presents important performance improvements in turning operation. Process parameters such as cutting speed, feed rate, cutting depth and tip radius were taken into consideration in a total of 540 experiments. The design of the experiment and a statistical analysis were performed to reveal significant process parameters. A special experimental setup was designed to measure in-situ cutting forces. The surface roughness of the machined surfaces was measured. An artificial neural network model was developed to predict optimum performance parameters.

Abstract
We present a detailed spectroscopic analysis of horizontal branch stars in the globular cluster NGC 3201. We collected optical (4580–5330 Å), high-resolution (∼34,000), high signal-to-noise ratio (∼200) spectra for 11 RR Lyrae stars and one red horizontal branch star with the multifiber spectrograph M2FS with the 6.5 m Magellan telescope at the Las Campanas Observatory. From measured equivalent widths, we derived atmospheric parameters and abundance ratios for α (Mg, Ca, and Ti), iron-peak (Sc, Cr, Ni, and Zn), and s-process (Y) elements. We found that NGC 3201 is a homogeneous, monometallic ([Fe/H] = −1.47 ± 0.04), α-enhanced ([α/Fe] = 0.37 ± 0.04) cluster. The relative abundances of the iron-peak and s-process elements were found to be consistent with solar values. In comparison with other large stellar samples, NGC 3201 RR Lyraes have similar chemical enrichment histories as do those of other old (t ≥ 10 Gyr) Halo components (globular clusters; red giants; blue and red horizontal branch stars; and RR Lyraes). We also provided a new average radial velocity estimate for NGC 3201 by using a template velocity curve to overcome the limit of single-epoch measurements of variable stars: Vrad = 494 ± 2 km s−1 (σ = 8 km s−1).
Restrictions on the Growth of Gas Giant Cores via Pebble Accretion
Authors: Rosenthal M. M. , Murray-Clay R. A. 
Published: August 2018

Abstract
We apply an order-of-magnitude model of gas-assisted growth, known as pebble accretion, in a turbulent medium to suggest a reason why some systems form wide orbital separation gas giants while others do not. In contrast to traditional growth by ballistic collisions with planetesimals, growth by pebble accretion is not necessarily limited by doubling times at the highest core mass. Turbulence, in particular, can cause growth to bottleneck at lower core masses. We demonstrate how a combination of growth by planetesimal and pebble accretion limits the maximum semimajor axis where gas giants can form. We find that, for fiducial disk parameters, strong turbulence (α ≳ 10−2) restricts gas giant cores to form interior to a ≲ 40 au, while for weak turbulence, gas giants can form out to a ≲ 70 au. The correspondence between α and semimajor axis depends on the sizes of small bodies available for growth. This dependence on turbulence and small-body size distribution may explain the paucity of wide orbital separation gas giants. We also show that while lower levels of turbulence (α ≲ 10−4) can produce gas giants far out in the disk, we expect these gas giants to be low-mass (M ≲ 1 M

J
). These planets are not luminous enough to have been observed with the current generation of direct-imaging surveys, which could explain why wide orbital separation gas giants are currently observed only around A stars.
Near-infrared Spectroscopy of Supernova 2017eaw in 2017: Carbon Monoxide and Dust Formation in a Type II-P Supernova
Authors: Rho J. , Geballe T. R. , Banerjee D. P. K. , Dessart L. , Evans A. , Joshi V. 
Published: August 2018

Abstract
The origin of dust in the early universe has been the subject of considerable debate. Core-collapse supernovae (ccSNe), which occur several million years after their massive progenitors form, could be a major source of that dust, as in the local universe several ccSNe have been observed to be copious dust producers. Here we report nine near-infrared (0.8–2.5 μm) spectra, obtained with GNIRS on Gemini North, of the Type II-P supernova (SN) 2017eaw in NGC 6946, spanning the time interval 22–205 days after discovery. The spectra show the onset of CO formation and continuum emission at wavelengths greater than 2.1 μm from newly formed hot dust, in addition to numerous lines of hydrogen and metals, which reveal the change in ionization as the density of much of the ejecta decreases. The observed CO masses estimated from a local thermodynamic equilibrium (LTE) model are typically 10−4
M
⊙ during days 124–205, but could be an order of magnitude larger if non-LTE conditions are present in the emitting region. The timing of the appearance of CO is remarkably consistent with the chemically controlled dust models of Sarangi & Cherchneff.
Formation of LISA Black Hole Binaries in Merging Dwarf Galaxies: The Imprint of Dark Matter

Published: August 2018

Abstract
Theoretical models for the expected merger rates of intermediate-mass black holes (IMBHs) are vital for planned gravitational-wave detection experiments such as the Laser Interferometer Space Antenna (LISA). Using collisionless N-body simulations of dwarf galaxy (DG) mergers, we examine how the orbital decay of IMBHs and the efficiency of IMBH binary formation depend on the central dark matter (DM) density profile of the merging DGs. Specifically, we explore various asymptotic inner slopes γ of the DG’s DM density distribution, ranging from steep cusps (γ = 1) to shallower density profiles (γ < 1), motivated by well-known baryonic-feedback effects as well as by DM models that differ from cold DM at the scales of DGs. We find that the inner DM slope is crucial for the formation (or lack thereof) of an IMBH binary; only mergers between DGs with cuspy DM profiles (γ = 1) are favorable to forming a hard IMBH binary, whereas when γ < 1 the IMBHs stall at a separation of 50–100 pc. Consequently, the rate of LISA signals from IMBH coalescence will be determined by the fraction of DGs with a cuspy DM profile. Conversely, the LISA event rates at IMBH mass scales offer in principle a novel way to place constraints on the inner structure of DM halos in DGs and address the core–cusp controversy. We also show that, with spatial resolutions of ∼0.1 kpc, as often adopted in cosmological simulations, all IMBHs stall, independent of γ. This suggests caution should be taken when employing cosmological simulations of galaxy formation to study BH dynamics in DGs.
Virtual World Interoperability: Let Use Cases Drive Design
Authors: Watte Jon 
Published: August 2018

Virtual worlds are slowly creeping into our daily lives. While some early
adopters have been using them for entertainment, research and training
over the last 20 years, virtual trade shows and online conferencing with
user avatars are putting them front and center on the desktops of workers
around the world. However, while a "walled garden" virtual world may be
useful in and of itself (just like a cell phone being able to call other
cell phone customers using the same carrier), the real usability
explosion will come when the different virtual worlds start talking to
each other (just like cell phones being able to call any phone number in
the world, no matter who the destination carrier or operator is).

This article will examine the history of virtual world interoperability
as evidenced through early systems like DIS and HLA, current systems such
as Second Life / OpenSim teleport and OLIVE simulation interoperability,
and will examine some common use cases for the future, interconnected
metaverse. Based on this learning, a comprehensive approach to
standards-based virtual world interoperability is described, and the
article ends with a call for action.

The author has a unique depth of perspective on virtual worlds
interoperability, having worked with a variety of technologies ranging
from military simulation all the way to massively multiplayer online
games, having worked for a leading virtual world platform provider
since 2001, and having shipped public virtual world interoperability
solutions since 2005.
Applying Constant Comparative and Discourse Analyses to Virtual Worlds Research
Authors: Leong Peter , Joseph Samuel R. H. , Boulay Rachel 
Published: August 2018

This paper presents the basics of the constant comparative analysis and discourse analysis methods to research in virtual worlds. Our data sources include video recordings of in-world class interactions; artifacts and documents such as students’ blog, and asynchronous discussion postings. For data analysis, we use the constant comparative method as a tool for inductive analysis, and discourse analysis as a tool to discover patterns in discursive practices. The constant comparative method was originally developed for the use in grounded theory methodology, but is now more widely applied as a method of analysis in qualitative research. It requires the researcher to take one piece of data and compare it to all other pieces of data that are either similar or different, gradually identifying the salient differences. In contrast, discourse analysis examines the way in which sentences are combined in larger linguistic units, such as conversational exchanges or written texts. The critical analysis of discourse helps us extend and specify themes generated during constant comparative analysis.
Synthesizing Presence: A Multidisciplinary Review of the Literature
Authors: Beck Dennis , Fishwick Paul , Kamhawi Rasha , Coffey Amy Jo , Henderson Julie 
Published: August 2018

This multidisciplinary literature review analyzed one hundred and eight peer-reviewed journal articles focusing on presence from four academic disciplines: Mass Communication, Human-Computer Interaction, Education, and Psychology. It was conducted because there was a need for a comprehensive, integrated understanding of presence. Results strongly indicate that presence includes both objective and subjective criteria, and thus should be measured in both ways. Results also showed that the different academic disciplines approach the concept in similar, yet distinct ways. These similarities and differences also gave the researchers the necessary content to create a presence ontology. Future researchers are encouraged to use these results and ontology as a starting point for formulating research questions that advance an understanding of presence.
Massively Multi-Player Online Role Playing Games: What’s the Risk?

Published: August 2018

Some may argue that the proliferation of personal computers together with the widespread use of the Internet has brought many benefits to society. The popularity of the internet and its associated online services continues to grow at an exponential rate and consequently, so does the number of avenues for potential exploitation. Prior research has already established that sexual predators and social engineers use the Internet as a means to target and exploit individuals. Indeed, previous studies highlight the significant threats faced by users of instant messaging and social networking facilities. Online role-playing games and virtual environments provide yet another platform for users to interact with one another. Evidence suggests that subscribers of such services often become so immersed in a fantasy world that their ability to differentiate between the virtual and real world is reduced. This monograph investigates the level of threat faced by users of virtual environments and online role-playing games. The study made use of an online survey to assess the current level of awareness and understanding amongst individuals who spend excessive amounts of time engaging in such environments.

Abstract. We assessed the influence of the marine diazotrophic cyanobacterium
Trichodesmium on the bio-optical properties of western tropical South
Pacific (WTSP)
waters (18–22∘ S, 160∘ E–160∘ W) during
the February–March 2015 OUTPACE cruise. We performed measurements of
backscattering and absorption coefficients, irradiance, and radiance in the
euphotic zone with a Satlantic MicroPro free-fall profiler and took
Underwater Vision Profiler 5 (UPV5) pictures for counting the largest
Trichodesmium spp. colonies. Pigment concentrations were determined
by fluorimetry and high-performance liquid chromatography and picoplankton
abundance by flow cytometry. Trichome concentration was estimated from
pigment algorithms and validated by surface visual counts. The abundance of
large colonies counted by the UVP5 (maximum 7093 colonies m−3) was
well correlated to the trichome concentrations (maximum
2093 trichomes L−1) with an aggregation factor of 600. In the
Melanesian archipelago, a maximum of 4715 trichomes L−1 was enumerated
in pump samples (3.2 m) at 20∘ S, 167 30∘ E. High
Trichodesmium abundance was always associated with
absorption peaks of
mycosporine-like amino acids (330, 360 nm) and high particulate
backscattering, but not with high Chl a fluorescence or blue particulate
absorption (440 nm). Along the west-to-east transect, Trichodesmium
together with Prochlorococcus represented the major part of total
chlorophyll concentration; the contribution of other groups were relatively
small or negligible. The Trichodesmium contribution to total
chlorophyll concentration was the highest in the Melanesian archipelago
around New Caledonia and Vanuatu (60 %), progressively decreased to the
vicinity of the islands of Fiji (30 %), and reached a minimum in the
South Pacific Gyre where Prochlorococcus dominated chlorophyll
concentration. The contribution of Trichodesmium to zeaxanthin was
respectively 50, 40 and 20 % for these regions. During the OUTPACE
cruise, the relationship between normalized water-leaving radiance
(nLw) in the ultraviolet and visible and chlorophyll
concentration was similar to that found during the BIOSOPE cruise in the
eastern tropical Pacific. Principal component analysis (PCA) of OUTPACE data
showed that nLw at 305, 325, 340, 380, 412 and 440 nm was
strongly correlated to chlorophyll and zeaxanthin, while nLw at
490 and 565 nm exhibited lower correlations. These results, as well as
differences in the PCA of BIOSOPE data, indicated that nLw
variability in the greenish blue and yellowish green during OUTPACE was
influenced by other variables associated with Trichodesmium
presence, such as backscattering coefficient, phycoerythrin fluorescence
and/or zeaxanthin absorption, suggesting that Trichodesmium
detection should involve examination of nLw in this spectral
domain.
