Abstract. During the monsoon season, pollutants emitted by large coastal cities and
biomass burning plumes originating from central Africa have complex transport
pathways over southern West Africa (SWA). The
Dynamics–Aerosol–Chemistry–Cloud Interactions in West Africa (DACCIWA) field
campaign has provided numerous dynamical and chemical measurements in and
around the super-site of Savè in Benin (≈185 km away from the
coast), which allows quantification of the relative contribution of advected
pollutants. Through the combination of in situ ground measurements with
aircraft, radio-sounding, satellite, and high-resolution chemistry-transport
modeling with the CHIMERE model, the source attribution and transport
pathways of pollutants inland (here, NOx and CO) are
carefully analyzed for the 1–7 July 2016 period. The relative contributions
of different sources (i.e., emissions from several large coastal cities) to
the air quality in Savè are characterized. It is shown that a systematic
diurnal cycle exists with high surface concentrations of pollutants from
18:00 to 22:00 UTC. This evening peak is attributed to pollution transport
from the coastal city of Cotonou (Benin). Numerical model experiments
indicate that the anthropogenic pollutants are accumulated during the day
close to the coast and transported northward as soon as the daytime
convection in the atmospheric boundary layer ceases after 16:00 UTC,
reaching 8∘ N at 21:00 UTC. When significant biomass burning
pollutants are transported into continental SWA, they are mixed with
anthropogenic pollutants along the coast during the day, and this mixture is
then transported northward. At night, most of the coastal anthropogenic
plumes are transported within the planetary boundary layer (below about
500 m above ground level), whereas the biomass burning pollutants are mostly
transported above it, thus generally not impacting ground level air quality.
Effectiveness of short term air quality emission controls: A
high-resolution model study of Beijing during the APEC period

Published: January 2019

Abstract. We explore the impacts of emission controls on haze events in Beijing in October–November 2014 using high resolution WRF-Chem simulations. The model reproduces surface temperature and relative humidity profiles over the period well and captures the observed variations in key atmospheric pollutants. We highlight the sensitivity of simulated pollutant levels to meteorological variables and model resolution, and in particular to treatment of turbulent mixing in the planetary boundary layer. We note that simulating particle composition in the region remains a challenge, and we overpredict NH4 and NO3 at the expense of SO4. We find that the emission controls implemented for the APEC Summit period made a relatively small contribution to improved air quality (20–26 %), highlighting the important role played by favourable meteorological conditions over this period. We demonstrate that the same controls applied under less favourable meteorological conditions would have been insufficient to reduce pollutant levels to meet the required standards. Continued application of these controls over the 6-week period considered would only have reduced the number of haze days where daily-mean fine particulate matter exceeds 75 μg m−3 from 15 to 13 days. Our study highlights the limitations of current emission controls and the need for more stringent measures over a wider region during meteorologically stagnant weather.
Radiative Forcing by Light-Absorbing Particles in Snow in Northeastern China Retrieved from Satellite Observations
Authors: Pu Wei , Cui Jiecan , Shi Tenglong , Zhang Xuelei , He Cenlin , Wang Xin
Published: January 2019

Abstract. Light-absorbing particles (LAPs) deposited on snow can decrease snow albedo and affect climate through the snow-albedo radiative forcing. In this study, we use MODIS observations combined with a snow albedo model (SNICAR) and a radiative transfer model (SBDART) to retrieve the radiative forcing by LAPs in snow (RFLapsMODIS) across Northeastern China (NEC) in January–February from 2003 to 2017. RFLapsMODIS presents distinct spatial variability, with the minimum (22.3 W m−2) in western NEC and the maximum (64.6 W m−2) near industrial areas in central NEC. The regional mean RFLapsMODIS is ~ 45.1 ± 6.8 W m−2 in NEC. The positive (negative) uncertainties of retrieved RFLapsMODIS due to atmospheric correction range from 14 % to 57 % (−14 % to −47 %) and the uncertainty value basically decreased with the increased RFLapsMODIS. We attribute the variations of radiative forcing based on remote sensing and find that the spatial variance of RFLapsMODIS in NEC is 74.6 % due to LAPs, while 21.2 % and 4.2 % due to snow grain size, and solar zenith angle. Furthermore, based on multiple linear regression, the BC dry and wet deposition and snowfall could totally explain 81 % of the spatial variance of LAP contents, which confirms the reasonability of the spatial patterns of retrieved RFLapsMODIS in NEC. We validate RFLapsMODIS using in situ radiative forcing estimates. We find that the biases in RFLapsMODIS are negatively correlated with LAP concentrations and range from ~ 5 % to ~ 350 % in NEC.

Published: January 2019

Abstract. We measured methane ebullition from a patterned boreal bog situated in the Siikaneva wetland complex in southern Finland. Measurements were conducted on water (W) and bare peat surfaces (BP) in three growing seasons 2014–2016 using floating gas traps. The volume of the trapped gas was measured weekly, and methane and carbon dioxide (CO2) concentrations of bubbles were analyzed from fresh bubble samples collected separately. We applied a mixed effects model to quantify the effect of the environmental controlling factors on the ebullition. Ebullition was higher from W than from BP, and more bubbles were released from open water (OW) than from water's edge (EW). On average, ebullition rate was the highest in the wettest year 2016 and ranged between 0–253 mg m−2 d−1, 0–147 mg m−2 d−1 and 0–186 mg m−2 d−1 in 2014, 2015 and 2016, respectively. Ebullition increased together with increasing peat temperature, weekly air temperature sum and atmospheric pressure, and decreasing water table (WT). Methane concentration in the bubbles released from W was 15–20 times higher and from BP 10 times higher than their CO2 concentration. The proportion of ebullition fluxes upscaled to ecosystem level for the peak season was 2–8 % and 2–5 % of the total flux measured with eddy covariance technique and with chambers and gas traps, respectively. Thus, the contribution of methane ebullition from wet non-vegetated surfaces of the bog to the total ecosystem-scale methane emission appeared to be small.
Characteristics and influencing factors of rainfall-induced landslide and debris flow hazards in Shaanxi Province, China
Authors: Zhang Ke , Wang Sheng , Bao Hongjun , Zhao Xiaomeng
Published: January 2019

Abstract. Shaanxi Province, located in northwest China and spanning multiple
hydroclimatic and geological zones, has many areas largely suffering from
rainfall-induced landslide and debris flow. The objectives of this study are
to reveal the spatiotemporal characteristics of the two hazards and identify
their major controlling factors in this region based on a region-wide,
comprehensive ground-survey-based hazard inventory dataset from 2009 to 2012.
We investigated the spatiotemporal characteristics of the two hazards and
quantified the relationships between the occurrence rates of the two hazards
and their influencing factors, including antecedent rainfall amount, rainfall
duration, rainfall intensity, terrain slope, land cover type and soil type.
The results show that landslide has a higher occurrence rate and more
extensive distribution than debris flow in this region, while the two hazards
are both concentrated in the south with ample rainfall and steep terrains.
Both of the hazards show clear seasonalities: July–September for landslide
and July for debris flow. Rainfall characteristics (amount, duration and
intensity) and slope are the dominant factors controlling slope stability
across this region. Debris flow is more sensitive to these rainfall metrics
on the high-value ranges than landslide in this region. Land cover is another
influencing factor but soil type does not appear to impose consistent impacts
on the occurrence of the two hazards. This study not only provides
important inventory data for studying the landslide and debris flow hazards
but also adds valuable information for modeling and predicting the two
hazards to enhance resilience to these hazards in this region.
New insight from CryoSat-2 sea ice thickness for sea ice modelling
Authors: Schröder David , Feltham Danny L. , Tsamados Michel , Ridout Andy , Tilling Rachel
Published: January 2019

Abstract. Estimates of Arctic sea ice thickness have been available from the CryoSat-2
(CS2) radar altimetry mission during ice growth seasons since 2010. We derive
the sub-grid-scale ice thickness distribution (ITD) with respect to five ice
thickness categories used in a sea ice component (Community Ice CodE, CICE)
of climate simulations. This allows us to initialize the ITD in stand-alone
simulations with CICE and to verify the simulated cycle of ice thickness. We
find that a default CICE simulation strongly underestimates ice thickness,
despite reproducing the inter-annual variability of summer sea ice extent. We
can identify the underestimation of winter ice growth as being responsible
and show that increasing the ice conductive flux for lower temperatures
(bubbly brine scheme) and accounting for the loss of drifting snow results in
the simulated sea ice growth being more realistic. Sensitivity studies
provide insight into the impact of initial and atmospheric conditions and,
thus, on the role of positive and negative feedback processes. During summer,
atmospheric conditions are responsible for 50 % of September sea ice
thickness variability through the positive sea ice and melt pond albedo
feedback. However, atmospheric winter conditions have little impact on winter
ice growth due to the dominating negative conductive feedback process: the
thinner the ice and snow in autumn, the stronger the ice growth in winter. We
conclude that the fate of Arctic summer sea ice is largely controlled by
atmospheric conditions during the melting season rather than by winter
temperature. Our optimal model configuration does not only improve the
simulated sea ice thickness, but also summer sea ice concentration, melt pond
fraction, and length of the melt season. It is the first time CS2 sea ice
thickness data have been applied successfully to improve sea ice model
physics.

Published: January 2019

El fenómeno de la radiodifusión universitaria tiene casi un siglo de recorrido, desde sus primeras experiencias en universidades de Estados Unidos y Argentina, pero este hecho no se corresponde con la investigación desarrollada sobre la materia. El objetivo del presente estudio es identificar y analizar la producción científica sobre radio universitaria publicada en revistas indexadas en la base de datos de Scopus en el periodo 2000-2017 a través de distintos indicadores bibliométricos. Los resultados muestran que existe una escasa producción bibliográfica (47 documentos), que se mantiene a lo largo del período analizado y va en claro aumento en el último lustro, así mismo la mayoría de documentos se aglutinan en instituciones estadounidenses, españolas y latinoamericanas. Una de las principales conclusiones, es que en España existe un creciente interés en este tema de investigación coincidiendo con la creación de la Asociación de Radios Universitarias de España (ARU).
La gestión de datos de investigación en el horizonte de las bibliotecas universitarias y de investigación.
Authors: Alonso-Arévalo Julio
Published: January 2019

La sociedad TIC necesita, hace uso y proporciona de una enorme cantidad de datos; procesarlos, entenderlos y transformarlos en decisiones de valor es el reto del análisis de los llamados "big data", un término utilizado para referirse a la explosión de una ingente cantidad y diversidad de datos digitales de alta frecuencia, que se están convirtiendo en un elemento esencial para la competencia, y que según la mayoría de los expertos en el tema serán clave para el crecimiento de la productividad, la innovación y la posibilidad de generar el suficiente excedente para la sostenibilidad de la sociedad. La gestión de los datos de investigación se plantea como uno de los grandes retos que han de asumir durante los próximos años las bibliotecas científicas y de investigación. Ya la mitad de las universidades estadounidenses tienen un plan de trabajo sobre esta cuestión, todos los informes de tendencias están de acuerdo en que la Gestión de Datos de Investigación (RDM) será una de las cuestiones prioritarias y de futuro que deberán asumir las bibliotecas de investigación. En este artículo se hace un análisis del estado de la cuestión sobre la gestión de datos de investigación, normativa, repositorios de datos, prácticas y políticas que están desarrollando las bibliotecas en torno al tema.
Identidades culturales a través de textos audiovisuales satíricos: El caso de "La Vida de Brian"
Authors: Valhondo Crego José Luís
Published: January 2019

Life of Brian parodies a mythical narrative of Western culture in order to satirize cultural stereotypes after May 1968, at the time of transition to an economic model of global deregulation of markets. Monty Python work with detachment strategies to reenchant a depleted political sphere; however, with regard to the problem of multiculturalism, his account does not offer solutions for the diversity of the publics. Neither the old nor the new Institutions are represented by offering viable political horizons. Christianity, the Establishment or the New Left are described with scepticism at best or cynically, at worst. In short, only the posture of perplexity and astonishment of Brian serves as a common value in the construction of a public sphere whose main trait is a postmodern oxymoron, the individualistic gregariousness

Published: January 2019

The aim of this study was to evaluate the oxidative stability of fresh lamb patties from Longissimus dorsi (LD) muscle, obtained from animals slaughtered at 10 months-age, during 9 days under refrigerated storage. Six batches (n = 6) of lamb patties were prepared and analyzed for thiobarbituric acid-reactive substances (TBARS), and for carbonyl content throughout 9 days at 4 °C. TBARS levels were stable (p > 0.05) during first five days of storage and a decrease (p < 0.05) in lipid oxidation was observed on day 9. Carbonyl content increased (p < 0.05) up to day 5, remaining constant (p > 0.05) from day 5 to day 9. We concluded that fresh lamb patties from LD muscle of animals slaughtered with 10 months of age was relatively stable to oxidative process during refrigerated storage without additional treatment, which may represent a viable and interesting alternative for refrigerated meat market.
“Prevent[ing] … Restless Spirits from Exciting Disturbances”: Benjamin Franklin and the Wyoming Valley
Authors: Mulford Carla J.
Published: January 2019

The controversy over the lands in the Wyoming Valley of Pennsylvania has been the stuff of legend (in stories of the Battle of Wyoming) and the historical record. Scholars in recent years have presented the history of the region as a contest between empires, between monied classes and common people seeking to eke out a living in a border region, and between individuals unsure of the political implications of democratic institutions. Left out of the narratives of the 1780s Wyoming controversy is a key figure who assisted in resolving the dispute: Benjamin Franklin. Biographers of Franklin have omitted discussion of his important intervention in the Wyoming events. Yet Franklin had a significant role to play as the controversy reached its resolution in the formation of the county of Luzerne.
Sense of coherence and work-related patterns of behavior and experience among faculty nurse educators in Egypt
Authors: Sharaf Amira Y. , Taha Eman E.
Published: January 2019

Background: Nursing education is associated with high intensity work and potential burnout. Sense of coherence mitigates the effect of job stress and enhances work wellness. This study aims to identify work-related patterns of behavior and experience among nurse educators and examine the independent relationship between sense of coherence and workplace behavior patterns.Methods: The study used a cross-sectional descriptive design and a sample of 130 nurse educators teaching in the Faculty of Nursing, Alexandria University, Egypt. The nurse educators completed questionnaires measuring sense of coherence and work-related patterns of behavior and experience.Results: Discriminant analysis delineated four work behavior patterns: healthy (16.2%), frugal (1.5%), overburdened (68.5%), and burnout (13.8%). Sense of coherence was positively associated with the healthy work pattern (r = .66, p < .001), and negatively associated with the burnout (r = -.63, p < .001) and overburdened (r = -.18, p < .05) patterns. Regression analyses, controlling for years of teaching experience, indicated that a weak sense of coherence was associated with classification of nurse educators into the overburdened work pattern (B = -.05, SE = .12, Wald χ2 = 13.13, p < .001) and the burnout work pattern (B = -.10, SE = .02, Wald χ2 = 21.52, p < .001) compared to healthy work pattern.}Conclusions: The study findings highlight the importance of sense of coherence as a health-promoting resource in the workplace. Strategies are discussed for creating meaningful work experiences to reinforce a sense of coherence and simultaneously cultivate work-related wellness among nurse educators.

Published: January 2019

El aumento de los hogares unipersonales en España, especialmente entre las mujeres mayores, su elevada esperanza de vida incluso en edades avanzadas, y el hecho de que hasta la fecha vienen percibiendo pensiones más bajas puede convertirlas en más vulnerables. El objetivo de este artículo es cuantificar desde un punto de vista actuarial las diferencias en el valor esperado de las pensiones contributivas para personas solteras y casadas que llegan a la edad de jubilación con una misma trayectoria laboral, haciendo especial énfasis en el sexo femenino. Suponiendo el cobro de pensiones medias, tanto solteras como casadas se encuentran en peor situación que sus homólogos masculinos, pero el monto total de pensiones contributivas para una mujer casada es hasta un 22,3% superior al de una mujer soltera.

Authors: García-Carro Beatriz , Sánchez-Sellero María Carmen
Published: January 2019

Ya que no es lo mismo «ser pobre» que «sentirse pobre», el objetivo es el tratamiento subjetivo de la pobreza mediante las líneas de Kapteyn y Deeleck, así como la obtención de indicadores (subjetivos y objetivos) calculados para los diferentes tamaños del hogar y en función de la densidad poblacional; todo ello a partir de la Encuesta de Condiciones de Vida (ECV) en España para los años 2008, 2012 y 2016. Concluimos que los hogares que se sienten pobres son más numerosos que aquellos que lo son, debido a la sobreestimación de las tasas subjetivas de Kapteyn y Deeleck. Obtuvimos umbrales de pobreza subjetiva similares para los tamaños de hogar más frecuentes. Los hogares son y se sienten menos pobres en las zonas o áreas geográficas más densamente pobladas.

sformułowanej przez Józefa Koniecznego oraz jakościowej teorii informacji Mariana
Mazura uogólnionej przez Józefa Kosseckiego. Ujęcie cybernetyczne pozwoliło na dokonanie
analizy procesu niszczenia informacyjnego odbywającego się w trakcie agresji
informacyjnej na społeczeństwa współczesnych państw, a w szczególności na zachodzące
w nich procesy informacyjne determinujące podejmowanie prawidłowych decyzji.
W pierwszej części artykułu zwrócono uwagę na zagrożenia współczesnych społeczeństw
wynikające z walki informacyjnej, która na obecnym etapie rewolucji informacyjnej
przybrała charakter powszechny. W drugiej części dzięki zastosowaniu
metod cybernetycznych zaprezentowano istotę i mechanizmy stojące za walką informacyjną.
W końcowej części sformułowano ogólne wnioski na temat walki informacyjnej,
która we współczesnych społeczeństwach stanowi szczególne zagrożenie dla
bezpieczeństwa i rozwoju państwa.
Zdaniem autorki cybernetyczne ujęcie tego zagadnienia może być przydatne do
planowania systemów ochrony i obrony informacyjnej państw, gdyż ich bezpieczeń-

Thermal stability of nanoscale oxides and
carbides of W and Zr in Cu-Al-Fe alloy
Authors: Zatulovskyi A.S. , Shcheretskyi V.O. , Shcheretskyi A.O.
Published: January 2019

Purpose: of this paper is to discover phases evolution of nanoscale tungsten, zirconium
oxides and carbides during heating up to 1200°C in contact with the copper alloy CuAl8Fe3.
Design/methodology/approach: The main investigation methods are X-ray phase
analysis and thermal analysis. The X-ray phase analysis is done by automated X-ray
diffractometer DRON-3.0 with cobalt anode, the thermal analysis is done with synchronous
thermal analyser STA 449F1 Jupiter (NETZSCH).
Findings: The initial interactions’ temperatures for the carbides and oxides with copper alloy
CuAl8Fe3, also temperatures of isomorphic and polymorphic transitions are discovered.
Comparative thermal analysis of the nanoscale powders reveals carbides are more stable in
air and inert gas (argon) versus oxides ones.
Research limitations/implications: Intermediate phase transitions during heating and
cooling are predicted on the base of known thermodynamic data and scientific reports, X-ray
phase analysis is performed only for initial and result material before and after heat treatment.
Practical implications: Obtained data allows developing effective technological
consolidation regimes of ESD nanoscale zirconium, tungsten carbides and oxides with
cuprum-based alloys for wear and heat resistant composite materials production.
Originality/value: The paper exposes new thermal data of isomorphic and polymorphic
transformations for zirconium, tungsten carbides and oxides nanoscale powders obtained
by ESD and their interactions with copper CuAl8Fe3 alloy in temperature range: 25-1200°C.
Properties of polylactide, obtained
from lactic acid in the process of lactic
fermentation of lactose in whey post
production (waste)
Authors: Maślanka S. , Juszczyński J. , Kraszewski T. , Oleksy W.
Published: January 2019

Purpose: This publication provides a description of RDC Glokor’s own research into the
effectiveness of the lactic fermentation process of lactose, lactic acid concentration and
polylactide (PLA) production by ring-opening polymerization obtained from the condensation
of two molecules of lactic acid. Furthermore, this publication sets out to determine potential
applications of the PLA as a commercial material with a selection of thermal properties.
Design/methodology/approach: In the described research works, a lactic fermentation
process was used in which lactose is converted to lactic acid with the participation of Lactic
Acid Bacteria. Polylactide was obtained indirectly by Ring Opening Polymerization and by
direct polymerization, straight from lactic acid, omitting the intermediate stages. Next, the
obtained lactide and polylactide were examined by spectroscopic methods (IR, NMR) to
determine their purity. Thermal methods (TG, DSC) to determine thermoplastic properties,
i.e. softening point, decomposition temperature and glass transition temperature.
Findings: Obtained from waste whey, PLA and its copolymers are excellent biodegradable
polymers that have the potential to be used in medicine as resorbable surgical strands,
biopolymers for implant production, as well as in many industries including for the production
of biodegradable bottles and disposable packaging, 3D printer cartridges.
Research limitations/implications: The research on lactic acid and lactide polymerization
described in this article is still a new issue that requires further research to optimize PLA
processes with industry-specific thermoplastic and physicochemical properties.
Originality/value: In the basic waste processing of milk, there is a large volume of whey
sour, which is ecologically dangerous for waste treating. Due to the high content of lactose
(up to 6%) this waste can be used as a raw material in the lactic fermentation process in
which lactose is converted to lactic acid with the participation of lactic acid bacteria. Lactic
acid can be concentrated and subjected to a dehydration process to lactide, which in the
final stage is subjected to the process of ring-opening polymerization in order to produce
biodegradable polylactide. The described process of carrying out the lactose contained in
PLA whey is an innovative way to obtain a biodegradable usable polymer, which can be used
to replace plastics such as polypropylene and polyethylene.
Posthuman affect in Margaret Atwood’s science fiction Oryx & Crake
Authors: Gonçalves Davi Silva , Rassier Luciana Wrege
Published: January 2019

Este artigo analisa o romance de Atwood Oryx & Crake (2003) para identificar se e de que forma seu desenvolvimento integra a crítica sobre o afeto no pós-humanismo. Assim, discutimos como a narrativa faz uso de artefatos distópicos da sociedade do século XXI para elaborar acerca da questão da conexão entre o humano e a máquina, bem como a falta de afeto resultante dela. O que a narrativa nos diz a respeito da influência da sociedade pós-humana na nossa relação afetiva com o meio ambiente, com a máquina e entre nós como sujeitos pós-humanos? É importante dizer que olhamos para o pós-humanismo de duas formas: como o momento de descreditar a ingenuidade humanista, bem como a sociedade fabricada no qual o humano e o pós-humano se veem irreversivelmente interligados. A discussão proposta, portanto, nos lembra da pertinência da distopia como um espelho da sociedade de onde ela emerge – especialmente no que concerne à novas perspectivas críticas fornecidas pela distopia pós-humana. A crítica frutífera articulada pelo mundo afetivo dos personagens de Oryx & Crake (2003) acerca do futuro pós-humano, onde tudo parece dar errado, é uma resposta à ideia questionável de que as distopias não teriam pertinência em um mundo que se vê supostamente isento da possibilidade de um regime político absolutista global.

Em Trilogia Cuiabana, destacam-se fragmentos poéticos da Cuiabá da infância do escritor Silva Freire. O efeito estético da Trilogia reside, porém, não só nos textos verbais que a integram, mas também na afetuosa edição e diagramação realizada por Wlademir Dias-Pino. As intervenções desse artista transformaram a obra em um mosaico de poemas, fotos, fragmentos de notícias, gravuras e desenhos. Nesse contexto, o presente artigo visa entender como os cortes, colagens e montagens de Dias-Pino, nos processos editoriais da Trilogia Cuiabana, ressignificam, à guisa de álbum de recortes, as lembranças poéticas de seu amigo Silva Freire, em exercício relacional da memória.
Escrever (sobre) os afetos: a escrita íntima de Annie Ernaux
Authors: Costa Leila De Aguiar
Published: January 2019

Os romances da francesa Annie Ernaux, considerados pela crítica literária como inscritos no contemporâneo gênero “autoficção”, parecem construir toda uma cenografia dos afetos que põe o Eu em diálogo com o Outro. O movimento dos afetos que perpassa obras como La Place (1983), Une femme (1987) e Journal du dehors (1993), quaisquer sejam seus fluxos ─ do interior para o exterior, do exterior para o interior ─ encenam a constituição mesma do sujeito, indelevelmente inscrita em uma comunidade, familiar, fraternal, coletiva. A proposta aqui é, pois, percorrer essas quatro autoficções procurando nelas reconhecer uma particular escrita do(s) afeto(s).
Representações da afetividade na literatura afro-brasileira de autoria feminina contemporânea
Authors: Pereira Rodrigo Da Rosa
Published: January 2019

Este trabalho busca investigar diferentes representações das afetividades na literatura afro-brasileira de autoria feminina contemporânea. Para tanto, tomamos por base alguns contos publicados na série literária Cadernos Negros. As noções de sororidade e matrifocalidade, bem como da espiritualidade afrodescendente colocam-se relevantes para compreendermos as relações de solidariedade e cooperação que se estabelecem nas narrativas em questão. Por outro lado, também verificam-se relações de vulnerabilidade afetivas, vistas como consequências negativas intimamente ligadas ao distanciamento da tradição afrodescendente.

This review seeks to integrate recent scientific findings on the behaviour of buffalo cows in different production systems. These issues are discussed in relation to the level of welfare that buffalo cows experience under different production systems. In extensive conditions, the level of welfare is high because the animals are free to express natural behaviours related to feeding (grazing, ruminating) and rest. In contrast, intensified livestock-raising methods and techniques (machine-milking, artificial breeding etc.), first developed for dairy cattle are increasingly being used with water buffaloes in order to increase milk production. Greater knowledge of the biology of dairy buffaloes in aspects linked to physiology, behaviour, and health, together with needed adjustments to their production systems, will indicate options for improving the levels of comfort and welfare of these animals and contribute to increasing the efficiency of this type of dairy production. It is necessary to appreciate the importance of welfare within the entire chain of animal production since each of the scientific aspects considered in this manuscript reflects that animal welfare is not an absolute term, but multidisciplinary, with direct consequences on productivity. The welfare of animals in the production systems must be considered with the aim of ensuring an adequate nutritional, clinical, sanitary and behavioural status of the animals. When these aspects are achieved, production can be maximized and, for this reason, it is essential to maintain a balance between welfare and productivity.
La importancia de los efectos espaciales en la deuda municipal
Authors: Balaguer Coll Maria Teresa , Ivanova Toneva Mariya
Published: January 2019

This article analyses the debt of local governments taking into account the presence of spatial interactions among neighbouring municipalities. To this end, the S2SLS and Spatial lag models were applied to a sample of 527 municipalities located in the Valencian Community (Spain) for the year 2015. The main results reveal a spatial correlation in outstanding debt among municipalities. The gender of the mayor, the grants and transfers received and the average payment period have direct effects on outstanding debt. In turn, the net savings index, inactive population, local income and the strength of the ruling political party have indirect effects on the municipal debt and indirect spatial effects on the debt of the neighbouring municipalities.

Este artículo analiza la deuda de los gobiernos locales teniendo en cuenta la presencia de interacciones espaciales entre los municipios vecinos. Para ello se utiliza una muestra 527 municipios de la Comunidad Valenciana, para el año 2015 y se aplican los modelos espaciales S2SLS y Spatial lag. Los principales resultados obtenidos muestran la existencia de autocorrelacion espacial en la deuda viva entre los municipios. Las variables género del alcalde, índice de subvenciones y transferencias recibidas y el periodo medio de pago presentan efectos directos sobre la deuda viva. Mientras que, el índice de ahorro neto, la población no activa, la renta local y la fortaleza política tienen efectos directos en la deuda del municipio y efectos espaciales indirectos en la deuda de los municipios vecinos.
Temas emergentes en contabilidad y control de gestión
Authors: Dávila Antonio
Published: January 2019

Organizations are at an interesting inflection point where existing paradigms are insufficient. The focus on execution as the main source of competitive advantage has been the dominant paradigm since the late 19th century. It is not enough. The dynamism brought by billions of people joining the market economy and by the exponential development across a large number of technologies requires complementing execution with managing for creation. Management accounting and control is not immune to these changes. Rather, its future development will determine its relevance to management. This paper reflects on some of the opportunities opening for this management discipline to keep its significance to managers. The paper explores new challenges in supporting execution and its role in creating new sources of value.

Las organizaciones están en un punto de inflexión donde los paradigmas existentes son insuficientes. El enfoque en la ejecución como la fuente más importante de ventaja competitiva ha sido el paradigma dominante desde el siglo XIX. No es suficiente. El dinamismo que ha traído el hecho de que más de mil millones de personas se hayan sumado a la economía de mercado y el desarrollo exponencial de un número significativo de nuevas tecnologías requiere complementar la ejecución con gestionar la creación. La contabilidad y control de gestión no son inmunes a estos cambios. Es más, su desarrollo en los próximos años determinará su relevancia para los gestores. Este artículo refleja algunas de las oportunidades que se están abriendo a esta disciplina de gestión para seguir siendo significativa para los ejecutivos de las organizaciones. El artículo explora los retos para seguir apoyando la ejecución así como su papel creando nuevas fuentes de valor.
Multilinear square functions and multiple weights
Authors: Grafakos Loukas , Mohanty Parasar , Shrivastava Saurabh
Published: January 2019

In this paper we prove weighted estimates for a class of smooth multilinear square functions with respect to multilinear $A_{\vec P}$ weights. In particular, we establish weighted estimates for the smooth multilinear square functions associated with disjoint cubes of equivalent side-lengths. As a consequence, for this particular class of multilinear square functions, we provide an affirmative answer to a question raised by Benea and Bernicot (Forum Math. Sigma 4, 2016, e26) about unweighted estimates for smooth bilinear square functions.
The reproducing kernel of $\mathcal H^2$ and radial eigenfunctions of the hyperbolic Laplacian
Authors: Stoll Manfred
Published: January 2019

In the paper we characterize the reproducing kernel $\mathcal {K}_{n,h}$ for the Hardy space $\mathcal {H}^2$ of hyperbolic harmonic functions on the unit ball $\mathbb {B}$ in $\mathbb {R}^n$. Specifically we prove that \[ \mathcal {K}_{n,h}(x,y) = \sum _{\alpha =0}^\infty S_{n,\alpha }(\lvert x\rvert )S_{n,\alpha }(\lvert y\rvert ) Z_\alpha (x,y), \] where the series converges absolutely and uniformly on $K\times \mathbb {B}$ for every compact subset $K$ of $\mathbb {B}$. In the above, $S_{n,\alpha }$ is a hypergeometric function and $Z_\alpha $ is the reproducing kernel of the space of spherical harmonics of degree α. In the paper we prove that \[ 0\le \mathcal K_{n,h}(x,y) \le \frac {C_n}{(1-2\langle x,y\rangle + \lvert x \rvert^2 \lvert y \rvert^2)^{n-1}}, \] where $C_n$ is a constant depending only on $n$. It is known that the diagonal function $\mathcal K_{n,h}(x,x)$ is a radial eigenfunction of the hyperbolic Laplacian $\varDelta_h $ on $\mathbb{B} $ with eigenvalue $\lambda _2 = 8(n-1)^2$. The result for $n=4$ provides motivation that leads to an explicit characterization of all radial eigenfunctions of $\varDelta_h $ on $\mathbb{B} $. Specifically, if $g$ is a radial eigenfunction of $\varDelta_h $ with eigenvalue $\lambda _\alpha = 4(n-1)^2\alpha (\alpha -1)$, then \[ g(r) = g(0) \frac {p_{n,\alpha }(r^2)}{(1-r^2)^{(\alpha -1)(n-1)}}, \] where $p_{n,\alpha }$ is again a hypergeometric function. If α is an integer, then $p_{n,\alpha }(r^2)$ is a polynomial of degree $2(\alpha -1)(n-1)$.
Bounded point derivations on $R^p(X)$ and approximate derivatives
Authors: Deterding Stephen
Published: January 2019

It is shown that if a point $x_0$ admits a bounded point derivation on $R^p(X)$, the closure of rational function with poles off $X$ in the $L^p(dA)$ norm, for $p >2$, then there is an approximate derivative at $x_0$. A similar result is proven for higher-order bounded point derivations. This extends a result of Wang which was proven for $R(X)$, the uniform closure of rational functions with poles off $X$.
La economía colaborativa: un nuevo modelo económico
Authors: Sastre-Centeno José Manuel , Inglada Galiana Elena
Published: January 2019

La denominada economía colaborativa está instalándose paulatinamente en la sociedad como un nuevo modelo económico, social, cultural e inclusive legal, fomentado por un cambio en múltiples valores y por las nefastas consecuencias de la crisis económica. También, las tecnologías de la información y la comunicación y la aparición de redes sociales son factores que han facultado la creación de nuevas formas de satisfacer las necesidades de las personas. Es un hecho que la economía colaborativa ha llegado con fuerza, con anhelos de cambiar muchas cosas y todo parece señalar que nos encontramos frente a un fenómeno destinado a persistir y a ampliar sus horizontes. No obstante, es importante no considerarla como una sustituta al sistema actual sino como un complemento que brinda más oportunidades y normaliza los modelos del consumo. Esta imparable economía se ha propagado a materias como el alquiler de viviendas, viajes, transportes o finanzas, entre otros muchos sectores. Estamos siendo testigos de un hecho patente con una justificación, el capitalismo sin control. Dicha realidad puede ser una solución a una recesión económica, puesto que permite el intercambio en casos de necesidad. Es la complementación favorable desde un enfoque renovador, económico, social y ecológico. El objetivo principal de este trabajo es ver en qué se ha convertido este nuevo movimiento en la actualidad y sus viables potencialidades.
RobOMP: Robust variants of Orthogonal Matching Pursuit for sparse representations
Authors: Loza Carlos A
Published: January 2019

Sparse coding aims to find a parsimonious representation of an example given an observation matrix or dictionary. In this regard, Orthogonal Matching Pursuit (OMP) provides an intuitive, simple and fast approximation of the optimal solution. However, its main building block is anchored on the minimization of the Mean Squared Error cost function (MSE). This approach is only optimal if the errors are distributed according to a Gaussian distribution without samples that strongly deviate from the main mode, i.e. outliers. If such assumption is violated, the sparse code will likely be biased and performance will degrade accordingly. In this paper, we introduce five robust variants of OMP (RobOMP) fully based on the theory of M-Estimators under a linear model. The proposed framework exploits efficient Iteratively Reweighted Least Squares (IRLS) techniques to mitigate the effect of outliers and emphasize the samples corresponding to the main mode of the data. This is done adaptively via a learned weight vector that models the distribution of the data in a robust manner. Experiments on synthetic data under several noise distributions and image recognition under different combinations of occlusion and missing pixels thoroughly detail the superiority of RobOMP over MSE-based approaches and similar robust alternatives. We also introduce a denoising framework based on robust, sparse and redundant representations that open the door to potential further applications of the proposed techniques. The five different variants of RobOMP do not require parameter tuning from the user and, hence, constitute principled alternatives to OMP.
