Homogeneidad y fragmentación en los hábitos alimentarios de los españoles. Una respuesta a través del análisis de los horarios, las relaciones y las normas alimentarias
Authors: Díaz Méndez Cecilia , García Espejo Isabel
Published: September 2018

Los procesos de modernización social y sus efectos han sido analizados también en el campo de la alimentación y hoy se discute acerca de la estabilidad o la desestructuración de los hábitos alimentarios. El objetivo de este artículo es contribuir a este debate con datos recientes procedentes de una encuesta de ámbito nacional sobre los hábitos alimentarios de los españoles (ENHALI 2012). Para ello se analizan tres áreas concretas: en primer lugar, la desestructuración de los horarios; en segundo lugar, se indaga si existe un proceso de desfamiliarización de la alimentación; en tercer lugar, se discute si estamos ante un hábito cuyas normas sobre el comer se han individualizado. Tras este estudio se puede afirmar que la sincronía horaria, la importancia que se le da a la sociabilidad y la adhesión a la norma alimentaria presentan una imagen más homogénea que desestructurada de los hábitos alimentarios de la sociedad española.
Género y commuting en las regiones urbanas andaluzas

Published: September 2018

Las diferencias entre mujeres y hombres en las distancias recorridas en los desplazamientos residencia-trabajo son un objeto recurrente en la literatura sobre movilidad, al constatar que las mujeres trabajan más cerca de casa. Sin embargo, el modo en el que estas diferencias operan es objeto de debate entre dos perspectivas: la teoría del enclaustramiento femenino y la teoría tradicional. La primera afirma que las diferencias entre sexos en la movilidad se deben al género, en concreto, a la mayor carga de trabajo doméstico de las mujeres y a la relegación de su rol laboral. Mientras la segunda hace énfasis en cómo estas diferencias se deben a factores intermedios, principalmente socioeconómicos. Nuestro objetivo consiste en contrastar ambas hipótesis para el caso andaluz, a través de la Encuesta Social 2011 de Movilidad en las Regiones Urbanas de Andalucía. Los resultados obtenidos apuntan a la complementariedad de las mismas, aunque operando las desigualdades de género más de manera indirecta, por vía segregación ocupacional, que directa.

Authors: Tello Diego Sebastián , De Prada Jorge Dante , Cristeche Estela Raquel
Published: September 2018

Introducción: El bosque nativo de caldén es un ecosistema natural que produce bienes y servicios ecosistémicos valiosos para la sociedad; no obstante, ha sido reemplazado para la producción de bienes comerciales, agrícolas y ganaderos.Objetivo: Estimar el valor económico de un programa de conservación de los servicios ecosistémicos del remanente del bosque nativo de caldén (Prosopis caldenia Burkart) en el sur de la provincia de Córdoba, Argentina.Materiales y métodos: El área de estudio corresponde a un remanente del bosque de 37 648 ha. La disposición a pagar (DAP) se obtuvo a partir de una encuesta de valoración contingente; 361 cuestionarios fueron aplicados. La unidad de muestreo fue el hogar. Un muestreo probabilístico por conglomerados multiétapico se utilizó en la ciudad de Río Cuarto y un muestreo aleatorio simple en la localidad de Villa Huidobro.Resultados y discusión: La DAP estimada mostró un buen ajuste y la mayoría de los coeficientes estimados fueron estadísticamente significativos (P < 0.05) y consistentes con lo esperado. La DAP aumenta con el ingreso económico de los hogares y se reduce a medida que el monto por pagar consultado incrementa. La DAP por un programa de conservación del bosque nativo de caldén es de 52 ± 8 ARS (11.45 ± 1.76 USD) promedio mensual por hogar.Conclusión: La mayoría de la población urbana del sur de Córdoba no usa los servicios ecosistémicos del bosque; sin embargo, los hogares están dispuestos a pagar para mantener o aumentar los servicios ecosistémicos del bosque.

Introducción: La cantidad y calidad de combustibles forestales determinan la frecuencia, intensidad e impacto de un incendio. A pesar de los servicios ecosistémicos que proveen, poco se conoce de los humedales costeros como los manglares y selvas inundables.Objetivo: Determinar la carga de combustibles leñosos en humedales de la Reserva de la Biosfera La Encrucijada (REBIEN).Materiales y métodos: Los combustibles leñosos se cuantificaron en tres parajes donde existe asociación de manglares y selvas inundables. Se establecieron cuatro unidades de muestreo por tipo de vegetación en cada paraje. En esta evaluación se adaptó la técnica de intersecciones planares. La carga de combustible se cuantificó y comparó por tipo de vegetación, paraje y categoría diamétrica del material leñoso.Resultados y discusión: Las selvas inundables acumularon combustibles muertos en el rango 63.19 a 151.87 t·ha-1, mientras que los manglares acumularon entre 88.81 a 152.38 t·ha-1; la diferencia de cargas no fue estadísticamente significativa (F = 1.05; P = 0.31). Con respecto a la categoría diamétrica, las cargas de combustibles finos (de 0.01 a 0.60 cm) fueron diferentes significativamente entre los parajes de los manglares (F = 3.05; P = 0.04), y los combustibles medianos (de 2.51 a 7.50 cm), entre los parajes de las selvas inundables (F = 9.93; P = 0.006). Conclusión: La cuantificación de combustibles forestales fue posible en humedales costeros, como los manglares y selvas inundables, encontrando cargas hasta tres veces mayores que en otros ecosistemas de zonas templadas. La información obtenida apoyará la priorización de zonas favorables para incendios.

Introducción: La diversificación de portainjertos surge como consecuencia de la aparición de enfermedades y la necesidad de mejorar los rendimientos y la eficiencia productiva de las huertas.Objetivo: Establecer la relación que existe entre las características anatómicas del tallo de cuatro portainjertos de cítricos y el crecimiento inicial del injerto de lima persa ‘Tahiti’ (Citrus x latifolia Tanaka ex Q. Jiménez).Materiales y métodos: Se evaluaron los portainjertos limón ‘Volkameriano’ (C. volkameriana Tenn. & Pasq.), naranjo agrio (Citrus aurantium L.), naranjo trifoliado ‘Flying Dragon’ (Poncirus trifoliata var. monstrosa [T. Ito] Swingle) y naranjo trifoliado ‘Rubidoux’ (P. trifoliata [L.] Raf.). Se estableció el grado de correlación entre siete características del crecimiento inicial del injerto y ocho características del xilema secundario del tallo de los portainjertos.Resultados y discusión: El naranjo agrio y el limón ‘Volkameriano’ mostraron crecimiento más vigoroso; las variables evaluadas fueron 23 a 70 % mayores que con ‘Rubidoux’ y ‘Flying Dragon’. Los portainjertos agrio y ‘Volkameriano’ presentaron vasos del xilema de mayor área y en menor densidad, así como longitud de fibras y radios del xilema mayores; estas características se correlacionaron con valores mayores de longitud y diámetro de brote, velocidad de crecimiento, número de hojas y área foliar del brote del injerto. Un tamaño menor de los vasos, pero mayor densidad, ocasionaron el efecto contrario en el crecimiento del injerto.Conclusión: La densidad, diámetro y longitud de los vasos, y la longitud de las fibras mostraron correlaciones más altas con las variables del crecimiento, por lo que pueden usarse como características de predicción en el crecimiento de injertos.

Authors: Flores-Garnica José G. , Macías-Muro Alejandra
Published: September 2018

Introducción: La cartografía de áreas con mayor densidad de incendios forestales puede desarrollarse a través de la estimación de densidad kernel, la cual requiere la selección de una función y un ancho de banda (h). El valor h, cuando se define mediante procesos subjetivos (visuales), dependerá del conocimiento y experiencia del seleccionador.Objetivo: Proponer una alternativa estadística, basada en información de incendios forestales (2005-2013) del estado de Jalisco, México, para la selección de h como soporte en la estimación de la densidad kernel.Materiales y métodos: A través de siete técnicas se definieron 13 valores de h. El valor de h se seleccionó usando los estadísticos siguientes: raíz del error cuadrático medio, raíz del error medio cuadrático integrado, coeficiente de variación y porcentaje comparativo.Resultados y discusión: Los valores h obtenidos con las técnicas probadas se encontraron entre 2 550 y 41 906 m. Hubo gran variación en los resultados; el rango entre el valor máximo y el mínimo fue 39 356.34 m con una media de 10 936.74 ± 9 955.04 m. Lo anterior implica que no existe un proceso único y universal para todos los casos. De acuerdo con los criterios de validación, el valor de h estadísticamente más adecuado se encuentra entre 5 300 y 5 900 m; el resultado más cercano se obtuvo con la técnica distancia aleatoria media (5 395 m). Conclusión: Es posible seleccionar h bajo una perspectiva estadística práctica, evitando el uso de criterios subjetivos.

Introducción: El análisis histórico de la variabilidad climática representa un primer acercamiento para conocer la recurrencia de eventos como sequías e inundaciones, así como inferir posibles tendencias climáticas. Este estudio representa el primer análisis histórico en la Reserva de la Biosfera Sierra Gorda (RBSG).Objetivos: Desarrollar series dendrocronológicas con el ancho de anillo de Pinus greggii Engelm. ex Parl. y P. montezumae Lamb., determinar su potencial para reconstruir la variabilidad de la lluvia, y reconstruir, mínimamente, la variabilidad de la precipitación y su relación con El Niño Southern Oscillation (ENSO) para el último siglo.Materiales y métodos: En el suroeste de la RBSG se extrajeron 87 muestras de 29 árboles, de las cuales 15 (45 radios) correspondieron a P. greggii y 14 (42 radios) a P. montezumae. Los crecimientos se fecharon empleando técnicas dendrocronológicas.Resultados y discusión: La cronología generada, compuesta de 138 años (1877-2014), se correlacionó significativamente (P < 0.01) con la lluvia de enero-mayo. La reconstrucción de la variabilidad de precipitación estacional invierno-primavera indica que hay variación interanual e interdecadal. Se identificaron cuatro fuertes sequías (1887, 1951-1956, 1969-1972 y 2012) y dos periodos con excelente precipitación (1962-1967 y 1983-1993). Las sequías más fuertes en el suroeste de la RBSG sincronizan con eventos extremos reconstruidos para el norte del país con una recurrencia de 50 años.Conclusión: Pinus greggii y P. montezumae respondieron significativamente a la precipitación del periodo invierno-primavera, lo que permitió reconstruir la variabilidad de la lluvia en un periodo de 138 años. La variabilidad ha sido modulada de manera significativa por ENSO.

Introducción: En la Amazonía peruana, los troncos cortados de palma aceitera (Elaeis guineensis Jacq.) suelen quemarse para evitar el aumento de estos residuos. Estos troncos también se utilizan para la crianza de larvas Rhynchophorus palmarum (Linnaeus, 1758) Csiki E., 1936, que los lugareños usan como fuente de alimento.Objetivo: Establecer la relación que existe entre las características de los troncos cortados de E. guineensis y la crianza de larvas R. palmarum.Materiales y métodos: La investigación se hizo en tres distritos (San Pedro-Campo Verde, TahuayoNeshuya y Maronal-Curimaná) del departamento de Ucayali, Perú. La correlación del número de larvas de R. palmarum con la longitud y el diámetro del cilindro central del tronco se analizó mediante el coeficiente de Spearman (rs ). Asimismo, se determinó la clase de textura del suelo y se estableció la correlación con el número de larvas.Resultados y discusión: La longitud y diámetro de los troncos cortados de palma aceitera fueron diferentes (P < 0.05) en las tres localidades evaluadas. No existe relación del número de larvas de R. palmarum con la longitud y el diámetro de los segmentos del tronco. En cambio, la textura franco arcillosa del suelo está correlacionada positivamente con el número de larvas (rs = 1.00, P < 0.01). El número de larvas fue mayor en las muestras del distrito Tahuayo-Neshuya (145.67 ± 39.67; P < 0.0001).Conclusión: Las características del tronco de palma aceitera no están asociadas con el desarrollo de R. palmarum.
Exploring non-linear associations between atmospheric new-particle formation and ambient variables: a mutual information approach

Published: September 2018

Abstract. Atmospheric new-particle formation (NPF) is a very non-linear process that
includes atmospheric chemistry of precursors and clustering physics as well
as subsequent growth before NPF can be observed. Thanks to ongoing efforts,
now there exists a tremendous amount of atmospheric data, obtained through
continuous measurements directly from the atmosphere. This fact makes the
analysis by human brains difficult but, on the other hand, enables the usage
of modern data science techniques. Here, we calculate and explore the mutual
information (MI) between observed NPF events (measured at Hyytiälä,
Finland) and a wide variety of simultaneously monitored ambient variables:
trace gas and aerosol particle concentrations, meteorology, radiation and a
few derived quantities. The purpose of the investigations is to identify key
factors contributing to the NPF. The applied mutual information method finds
that the formation events are strongly linked to sulfuric acid concentration
and water content, ultraviolet radiation, condensation sink (CS) and
temperature. Previously, these quantities have been well-established to be
important players in the phenomenon via dedicated field, laboratory and
theoretical research. The novelty of this work is to demonstrate that the
same results are now obtained by a data analysis method which operates
without supervision and without the need of understanding the physics deeply. This suggests that the method is suitable to be implemented
widely in the atmospheric field to discover other interesting phenomena and
their relevant variables.
OMI surface UV irradiance in the continental United States: quality assessment,
trend analysis, and sampling issues
Authors: Zhang Huanxin , Wang Jun , Castro García Lorena , Liu Yang , Krotkov Nickolay A.
Published: September 2018

Abstract. Surface full-sky erythemal dose rate (EDR) from Ozone Monitoring Instrument (OMI) at both satellite overpass time and local noon time are evaluated against ground measurements at 31 sites from USDA UV-B Monitoring and Research Program over the period of 2005–2017. We find that both OMI overpass time and local solar noon EDR are highly correlated with the measured counterparts (R = 0.88). Although the comparison statistics are improved with longer time window used for pairing surface and OMI measurements, OMI data overall has ~ 4 % underestimate for overpass EDR while ~ 8 % overestimate for the solar noon time EDR. The biases are analyzed regarding the spatial and temporal data collocation, the effects of solar zenith angle (SZA), clouds and the assumption of constant atmospheric conditions. The difference between OMI overpass EDR and ground observation shows some moderate dependence on SZA and the bias could be up to −30 % with SZA greater than ~ 65°. In addition, the ratio of EDR between solar noon to overpass time is often (95 % in frequency) larger than 1 from OMI products; in contrast, this ratio from ground observation is shown to be normally distributed around 1. This contrast suggests that the current OMI surface UV algorithm would not fully represent the real atmosphere with the assumption of a constant atmospheric profile between noon and satellite overpass times. The viability of surface UV in terms of peak UV frequency is also studied. Both OMI Noon_FS and ground peak EDR show a high frequency of occurrence of ~ 20 mW m−2 over the period of 2005–2017. However, another high frequency of ~ 200 mW m−2 occurs in OMI solar noon EDR while the ground peak values show the high frequency around 220 mW m−2, implying that the OMI solar noon time may not always represent the peak daily UV values. Lastly, OMI full-sky solar noon EDR shows statistically significant positive trends in parts of the northeastern U.S., the Ohio River Valley region and California. However, the UV trends estimated from ground-based network using two sampling methods (one corresponds to the OMI noon time and one averages all the data in a day) show significant negative trends in the Northeast and the Ohio River Valley region, which is consistent with the increase of absorption aerosol optical depth as revealed by OMI aerosol product in these regions. No statistically-significant trend can be found for OMI columnar O3 or cloud optical depth. The future surface UV data estimated with better spatial and temporal resolution obtained from geostationary satellites would help resolve these discrepancies found in the biases and estimated surface UV trends.
Dynamic changes of optical and chemical properties of tar ball aerosols by atmospheric photochemical aging

Published: September 2018

Abstract. Following wood pyrolysis, tar ball aerosols were generated from wood tar separated into polar and nonpolar phases. Chemical information of fresh tar balls was obtained from the high-resolution time-of-flight aerosol mass spectrometer (HiRes-ToF-AMS) and laser desorption/resonance enhanced multiphoton ionization mass spectrometry (LD-REMPI-MS), and their refractive index between 365 and 425 nm were retrieved using a broadband cavity enhanced spectroscopy. Dynamic changes of the optical and chemical properties for the nonpolar tar ball aerosols in NOx-dependent photochemical process were investigated in an oxidation flow reactor (OFR). Distinct differences in the chemical composition of the polar and nonpolar tar aerosols were identified. Nonpolar tar aerosols contain predominantly high-molecular weight unsubstituted and alkyl-substituted polycylic aromatic hydrocarbons (PAHs), while polar tar aerosols consist of a high number of oxidized aromatic substances (e.g., methoxy-phenols, benzenediol) with higher O : C ratio and carbon oxidation state. Fresh tar aerosols have light absorption characteristics similar to atmospheric BrC with higher absorption efficiency towards the UV wavelengths. The average retrieved refractive index (RI) are 1.661 + 0.020i and 1.635 + 0.003i for the nonpolar and polar tar aerosols, respectively, with absorption Ångström exponent (AAE) between 5.7 and 7.8 in the wavelength region 365–425 nm. The RI fits a volume mixing rule for internally mixed nonpolar/polar tar aerosols. The RI of the tar aerosols decreased with increasing wavelength under photochemical oxidation. Photolysis by UV light (254 nm), without strong oxidants in the system, slightly decreased the RI and increased the oxidation state of the tar balls. Oxidation under varying OH exposure levels and in the absence of NOx diminished the absorption (bleaching), and increased the O : C ratio. The photobleaching of tar ball aerosols via photochemically induced OH-oxidation is mainly attributed to decomposition of chromophoric aromatics, nitrogen-containing organics, and high-molecular weight components. Photolysis of nitrous oxide (N2O) was used to simulate NOx-dependent photochemical aging of tar balls in the OFR. Under high NOx conditions, photochemical aging lead to the formation of organic-nitrates, increased oxidation degree and increased absorption for the tar ball aerosols. These observations suggest that secondary organic nitrate formation compensates the bleaching by photolysis and OH radical photooxidation to eventually regain some absorption of aged tar balls aerosols. The atmospheric implication and climatic effects from tar balls upon various oxidation processes are briefly discussed.

Abstract. As commonly observed in oligotrophic stratified waters, a Subsurface (or Deep) Chlorophyll Maximum (SCM) frequently characterizes the vertical distribution of phytoplankton chlorophyll in the Mediterranean Sea. Occurring far from the surface layer seen by ocean color satellites, SCMs are difficult to observe with adequate spatio-temporal resolution and their biogeochemical impact remains unknown. BioGeochemical-Argo (BGC-Argo) profiling floats represent appropriate tools for studying the dynamics of SCMs. Based on data collected from 36 BGC-Argo floats deployed in the Mediterranean Sea, our study aims to address two main questions: (1) What are the different types of SCMs in Mediterranean Sea? (2) Which environmental factors control their occurrence and dynamics? First, we analyzed the seasonal and regional variations of the chlorophyll concentration (Chla), particulate backscattering coefficient (bbp), a proxy of the Particulate Organic Carbon (POC), and environmental parameters (PAR and nitrates) within the SCM layer over the Mediterranean basin. The vertical profiles of Chla and bbp were then statistically classified, and the seasonal occurrence of each of the different types of SCMs quantified. Finally, a case study was performed on two contrasted regions and the environmental conditions at depth were further investigated to understand which parameter controls the SCMs. In the Eastern Basin, SCMs result, at a first order, from photoacclimation process. Conversely, SCMs in the Western Basin reflect a biomass increase at depth benefiting from both light and nitrate resources. Our results also suggest that a variety of intermediate types of SCMs are encountered between these two end-member situations.
Brief Communication: Early season snowpack loss and implications for over-snow vehicle recreation travel planning
Authors: Hatchett Benjamin J. , Eisen Hilary G.
Published: September 2018

Abstract. Over-snow vehicle recreation contributes to rural economies but requires a minimum snow depth to mitigate negative impacts. Daily snow water equivalent (SWE) observations from weather stations in the Lake Tahoe region (western USA) and a SWE reanalysis product are used to estimate the onset dates of SWE corresponding to ~ 30 cm snow depth (SWEmin). Since 1985, median timing of SWEmin has increased by approximately two weeks. Potential proximal causes of this delay are investigated; rainfall is increasing during October-December with dry days also becoming more frequent. Adaptation strategies to address over-snow vehicle management challenges in recreation travel planning are explored.

Published: September 2018

Exclusive breastfeeding’s coverage is low in Indonesia, because attitude, subjective norm and perceived behavioral control fail affecting exclusive breastfeeding intention and behavior. Objectives of research were to formulate exclusive breastfeeding behavior and to explore the relationship of attitude, subjective norm, and behavioral control to exclusive breastfeeding intention and behavior. Mixed method was conducted in rural areas of Karanganyar Regency, Indonesia. Firstly, this was a survey research with attitude, subjective norm, and perceived behavioral control being independent variables. Dependent variables were exclusive breastfeeding intention and behavior. Population of research consisted of 873 lactating mothers. Sampling technique employed was multistage random sampling, with 126 lactating mothers being the sample. Data was collected using questionnaire, data analysis using path analysis. Secondly, case study was conducted through in-depth interview, focus group discussion (FGD), document review, and observation. In-depth interview and FGD was conducted with 49 participants: 30 lactating mothers and 19 health workers. Data analysis was conducted content analysis. The result showed that attitude, affective norm, and perceived behavioral control correlated with exclusive breastfeeding intention (ß = 0.09; p = 0.084; ß = 0.09; p = 0.027; ß = 0.51; p <0.001, respectively). Perceived behavioral control and intention correlated with exclusive breastfeeding behavior (ß = 0.08; p = 0.059; ß = 0.09; p = 0.068, respectively). Exclusive breastfeeding behavior model included attitude, subjective norm, perceived behavioral control, and exclusive breastfeeding behavior. Attitude, subjective norm, and perceived behavioral control collectively correlated with intention; intention and perceived behavioral perception were direct determinants of exclusive breastfeeding behavior.

Published: September 2018

Este trabalho é o segundo momento de reflexões sobre a rede de projeções por inversão, um conceito apresentado anteriormente em nosso artigo “Rede de Projeções por Inversão, Relações entre Tonnetze de Diferentes Tricordes” (ALBUQUERQUE e SALLES: 2017). Retomaremos a nosso estudo sobre este esquema de organização harmônica que foi desenvolvido a partir da necessidade de encontrar um modelo que pudesse relacionar conjuntos de classes de alturas de distintas espécies e diferentes cardinalidades, uma demanda aparentemente não contemplada por propostas neorriemannianas tradicionais. Nosso sistema foi construído calcado nas concomitâncias entre conjuntos implícitos em diferentes Tonnetze gerados a partir de inversões de todas as possibilidades de tricordes, revelando importantes propriedades simétricas implícitas em uma ampla extensão no universo cromático. Nosso trabalho se ampara na discussão promovida por teóricos dedicados ao desenvolvimento de ferramentas analíticas especializadas para o estudo do repertório pós-tonal, se inclinando em particular para o consórcio entre parâmetros oriundos da teoria dos conjuntos e da teoria neorriemanniana.
O conceito de ethos na música da Antiguidade Clássica grega
Authors:   Universidade de Brasília, Portugal Tales Pimentel , Correa Antenor Ferreira ,   Universidade de Brasília
Published: September 2018

No presente texto, apresentamos considerações sobre o conceito de ethos no ideário da Antiguidade Clássica. Duas obras foram tomadas como ponto de partida para essas considerações: A república de Platão e A política de Aristóteles. A partir do confronto entre esses dois filósofos foi possível discorrer sobre a maneira como concebiam a transmissão de emoções e o impacto no caráter dos cidadãos causado pela música, bem como a transformação do posicionamento de ambos em relação à função da música na sociedade. No âmbito dessa argumentação, concluímos que a compreensão mais ampla do conceito de ethos é primordial para o entendimento do pensamento musical dos autores e compositores desde a Antiguidade Clássica até, no mínimo, a Renascença.
Apocryphal media: an archaeology of mediated paranormal presence
Authors: Bernico Matthew
Published: September 2018

Technology does not just encompass tools for humans to master and use, but also cultural objects that play a role in one’s imagination of what is possible. Apocryphal media is a new taxonomic category within Media Archaeology that helps understand the impossible demands and expectations a user might make of a technology. Briefly, Apocryphal media are devices for which there exists an incongruity between the effects one expects the device to produce and what it actually produces. For example, there is an expectation that an electromagnetic field (EMF) reader can detect paranormal entities, but in fact, through the study of the discursive object, it only produces the effect of detecting paranormal entities. Starting with the most spectacular examples, this essay investigates the discursive structures surrounding the tools of paranormal investigation and the discourse surrounding their impossible effects.
Modernidad, progreso y desarrollo: imaginarios de futuro alrededor de la minería del oro en Colombia
Authors: Parra Mayra Natalia , Cano Wilmar Alexander
Published: September 2018

In Colombia, imaginaries of the future woven around gold mining have been shaped and cemented through the promotion of images and figures linked to discourses of progress, development, modernity and wealth. This paper outlines a historical overview of these various imaginaries, clearly showing that, while some differences exist between periods, continuities can be observed among representation schemes built to perceive and conceive mining as well as its relationship with the future. It is argued that the mining activity has relied on narratives with fundamentally symbolic and cultural dimensions, which has enabled its establishment, consolidation and expansion across Colombia since the early twentieth century. The paper concludes that there are conflicting imaginaries about mining today, additionally, it points out that the predominance of pro-mining narratives poses a major threat as they tend to legitimize the ruling power, to prevent the emergence of alternative models of society and to make dissenting voices invisible.

Authors:   Universitat Oberta de Catalunya, Tamarit Sumalla Josep Maria
Published: September 2018

El uso masivo de las TIC por parte de los niños y adolescentes les expone a formas de interacción sexual online con adultos que tienen elementos comunes con el abuso sexual offline. Ante ello, es necesario definir las diferencias existentes entre ambos fenómenos de cara a garantizar que la prevención de las potenciales víctimas se realice de un modo compatible con el principio de proporcionalidad, con la consiguiente necesidad de diferenciación de la respuesta penal. Para ello se indagan cuáles son las características propias de la victimización en línea y los efectos de la misma en las víctimas, se aborda el problema de la identificación de los bienes jurídicos protegidos y se concluye con una serie de recomendaciones de reforma legislativa y aplicación restrictiva de los tipos penales.

Аутор у раду врши анализу овлашћења високог представника и њего-вог дјеловања, с циљем да одговори на питање да ли се Босна и Херцего-вина може назвати државом, тј. да ли је она суверена. Сувереност каокључно својство државне власти јесте својство које мора имати свакадржава, односно говорити о несувереној држави је contradictio in adiecto,а управо то указује на важност ове теме.Приликом разматрања ове теме, коришћено је неколико метода сциљем да се из различитих углова сагледа овај проблем, те дâ коначансуд о суверености Босне и Херцеговине. Првенствено, примијењен је по-зитивноправни метод, којим се анализирају одговарајући акти, нарочитоУстав Босне и Херцеговине и Дејтонски мировни споразум, чије је диои сâм Устав, али и одлуке Уставног суда БиХ, те одлуке високог пред-ставника. Даље, аутор се користи историјским методом како би се уочиоразвој улоге високог представника у постдејтонском периоду, као и логич-ким методом, који је неопходан приликом тумачења Анекса 10 Општегоквирног споразума о миру у Босни и Херцеговини. Такође, коришћени суи политиколошки метод, зарад указивања на неефикасност коју изазивајуполитички чиниоци, као и нормативни метод, којим указујемо на неоства-реност дејтонских циљева. Сви методи имају циљ да испитају правну ифактичку страну положаја и дјеловања високог представника, зарад да-вања коначног одговора на горе поменуто питање.На одговарајућим мјестима су de lege ferenda изложени ставови о ту-мачењу овлашћења високог представника, који је неријетко вршио функциједржавне власти, те на тај тачин субординирао себи државне органе. Ау-тор на крају закључује да је улога високог представника временом ослабила,те да Босна и Херцеговина има прилику да постане држава у пуном обиму,а остварење тог циља је могуће само без учешђа међународних чинилаца.
Empathy and Osteopathic Manipulative Medicine: Is It All in the Hands?
Authors: Rizkalla Mireille N. , Henderson Kyle K.
Published: September 2018

Context

The osteopathic medical school curriculum is unique because of the inclusion of training in osteopathic manipulative medicine (OMM). Interest in and use of OMM promotes cognitive training in diagnosing conditions, emotional training in the alleviation of pain, and physical training in the application of OMM. Osteopathic manipulative medicine may mitigate a reduction in empathy levels of medical students and explain why osteopathic medical students do not follow the declining pattern of empathy previously reported in allopathic medical students.

Objective

To examine whether favorable opinions of OMM are positively correlated with overall student empathy as well as the cognitive, emotional, and behavioral subcomponents of empathy.

Methods

Institutional review board approval was obtained to measure empathy in medical students attending the Midwestern University/Chicago College of Osteopathic Medicine for this cross-sectional study. The 20-item Jefferson Scale of Empathy medical student version (JSE-S) was distributed via email to first-year students at the beginning of the 2016-2017 academic year and at the end of the academic year to all students. Items were divided into cognitive, emotional, and behavioral categories. Items related to demographics, interest and use of OMM and the osteopathic philosophy, frequency of touch, and personality were also included in the survey. Data were analyzed using SPSS software and presented as mean (SEM). Statistical significance was set at P<.05.

Results

Of the 801 students the survey was sent to at the end of the 2016-2017 academic year, 598 students completed the survey, for a response rate of 75%. When accounting for the effect of gender with a multivariate analysis of covariance, there were no differences in empathy scores across school years. When empathy scores from first- and second-year students were combined and compared with combined third- and fourth-year students’ scores to examine the difference between empathy in students during academic and clinical training, a difference in the mean (SEM) JSE-S empathy score was noted (114.6 [0.7] and 112.0 [0.7], respectively; P=.01); however, the effect size was small (partial η2=0.01). Interest in OMM and the osteopathic philosophy were significantly associated with higher empathy scores (P<.05; medium effect; partial η2=0.08).

Conclusion

Interest in and use of OMM are associated with higher empathy scores and empathy subcomponents. Training and use of OMM should be examined as a mechanism contributing to the durability of empathy in the osteopathic medical profession.

Cognitive impairment is common in patients with pain. While symptoms of pain are effectively treated with osteopathic manipulative treatment (OMT), the cognitive complaint is vastly ignored. Pain-induced cognitive dysfunction can be severe and is particularly apparent in working memory and attention. There is good reason to expect cognitive responsiveness to OMT. Previous research has reported the effects of OMT on related psychiatric outcomes, including relief from depression and anxiety, suggesting that OMT may produce more cortical benefits than is currently thought. The rationale to link OMT to cognition comes from the tenets of osteopathic medicine: body unity, homeostasis, and the structure-function relationship. The present article provides background evidence to support the hypothetical link between OMT and cognitive benefits and proposes a physiological mechanism of how OMT could exert its effect on cognition. Research strategies are discussed to test the hypotheses that are generated from the proposed theoretical framework.
Web-Based Language Learning (WBLL) for Enhancing L2 Speaking Performance: A Review
Authors: Cong-Lem Ngo
Published: September 2018

The advent of Web 2.0 technology has afforded language educators more useful technology for English as a foreign language (EFL) teaching. This article reviewed 31 empirical studies investigating the employment of web-based technology to enhance EFL learners’ speaking performance. The findings indicated that overall, web-based language learning (WBLL) could be classified into five major groups: general websites providing linguistic inputs, blogging platforms, communication tools, project-based learning tools and learning management systems. While the available linguistic input online, e.g. web articles and videos, helped to enhance learners’ linguistic and background knowledge, other communication/chat tools facilitated peer interactions and collaborative learning. Audio- and video-based blogging provided convenient platforms for learners to practice their speaking through sharing their personal experiences. Moreover, Web 2.0 technology as a learning management system helped to create a ubiquitous learning environment, where L2 learners could engage in the language learning process without time and space constraints. WBLL was also found to reduce L2 learners’ learning anxiety while making them become more active, motivated language learners. In addition, the role of language instructor in web-based technology implementation was also found to be crucial, e.g. monitoring L2 learners’ learning progress and providing feedback. Further research, however, is warranted to address existing methodological drawbacks of previous studies by recruiting larger sample size, conducting long-term research and controlling for confounding factors, e.g. prior L2 speaking ability and technology usage experience.
Wave Trajectory Study on the Coast of Lhoknga, Aceh Besar, Indonesia: A Numerical Model Approach
Authors: Setiawan Ichsan , Irham Mohammad
Published: September 2018

A numerical model of wave trajectory using shoaling and refraction formula was proposed in the coastal waters of Lhoknga, Aceh Besar, Indonesia. The developed model used a two dimensional (2D) numerical methods for wave trajectory with the input of wave height and period; 0.62 m and 8 second for high tide and 0.47 m and 6 second for low tide. This model was tested on site during low tide and high tide conditions for verification. The purpose of this numerical study is to trace the distribution of wave trajectory because of shoaling, wave breaking, and wave refraction. The model determines the wave height and crest pattern of the ray wave trajectory. The simulation result shows the pattern of the wave propagation at Lhoknga beach moves from the northwest to the east and south of the coast. The model also informs that the maximum wave height during high tide condition is 1.72 m and 1.31 m during low tide condition. The result indicates that the coast of Lhoknga has moderate wave conditions caused by a gentle beach bathymetry slope.
Does Auditor Industry Expertise Improve Audit Quality In Complex Business Environments?
Authors: Butar-Butar Sansaloni , Lily Indarto Stefani Lily Indarto
Published: September 2018

This study examines the role of specialist auditors in enhancing the quality of financial statements by taking into account industry complexity. The test of hypotheses are conducted in two steps. The first step is to provide evidence that earnings quality, measured by earnings persistent, of firms operating in the complex and non-complex industry are different. The second step is to compare the absolute abnormal accruals of companies engaged in the complex industry with those from non-complex industry audited by non-specialist and specialists auditors. Results show: 1) earnings persistence of firms in complex industries are lower than those in non-complex industries. 2) absolute abnormal accruals of firms operating in complex industries are higher than those in non-complex industries regardless industry specialization. Overall, the results suggest that auditor industry expertise does not play a significant role in improving the quality of audited earnings in complex business environ­ment.

Thioredoxin interacting protein (TXNIP) is a novel tumor suppressor that is down‐regulated in several cancer tissues and tumor cell lines. Overexpression of TXNIP causes cell cycle arrest at the G1/S checkpoint in the hepatocellular carcinoma cell line HuH‐7. TXNIP contains putative phosphorylation sites, but the effects of its phosphorylation have not been fully characterized. TXNIP also contains two α‐arrestin domains (N‐arrestin and C‐arrestin) whose functions are not fully understood. Here, we reveal an association between TXNIP and cell cycle regulatory proteins (p27kip1, Jun activation domain‐binding protein 1 (JAB1), Cdk2, and cyclin E), suggesting its participation in cell cycle regulation. We observed phosphorylation of TXNIP and used both in vivo and in vitro kinase assays to demonstrate that TXNIP can be phosphorylated by p38 mitogen‐activated protein kinase. Furthermore, we also identified Ser361 in TXNIP as one of the major phosphorylation sites. Cell cycle analysis showed that Ser361 phosphorylation participates in TXNIP‐mediated cell cycle arrest. In addition, the C‐arrestin domain may also play an important role in cell cycle arrest. We also showed that phosphorylation at Ser361 may be important for the association of TXNIP with JAB1 and that the C‐arrestin domain is necessary for the nuclear localization of this molecule. Collectively, these studies reveal that TXNIP participates in cell cycle regulation through association with regulatory proteins, especially JAB1, and that C‐arrestin‐dependent nuclear localization is important for this function. This work may facilitate the development of a new cancer therapy strategy that targets TXNIP as a key molecule inhibiting cancer cell growth via cell cycle blockade at the G1/S checkpoint.
