PROPERTIES AND MANAGEMENT IMPLICATIONS OF SOILS FORMED FROM VOLCANIC MATERIALS IN LEMBANG AREA, WEST JAVA
Authors: Yatno Edi , Zauyah Siti 
Published: October 2016

Soils formed from volcanic materials have a high potential for agricultural development, especially for horticultural crops, tea, and pine trees. Data on the characteristics of these soils are important for the management planning. Six representative soil profiles developed on andesitic volcanic ash and tuff in Lembang area, West Java were studied to determine the soil physical, chemical, and mineralogical properties, to study the relationship between the soil properties, and to classify the soils according to the Soil Taxonomy. The results indicated that all the soils had very deep (&gt;150 cm) solum. In general, the volcanic ash soils were darker colored, more granular, more friable, less sticky and less plastic than the volcanic tuff soils. Physically, the ash soils had lower bulk density (0.44-0.73 mg m-3) and higher available water content (13-33%) than the tuff soils. Bulk density decreased with increasing allophane. Chemically, the ash soils had higher pHNaF (mostly &gt; 10), higher organic carbon (4.3-6.8% in upper horizons), higher CEC (20- 44 cmolc kg-1), and higher P retention (&gt; 85%) than the tuff soils. P retention logarithmically increased with increasing oxalate extractable Al and allophane. The sand fractions of the ash soils were dominated by hornblende, while the tuff soils were predominantly composed of opaque minerals. In the clay fractions, the ash soils were dominated by allophane, whereas the tuff soils showed high contents of gibbsite and metahalloysite. Soils developed on volcanic ash were classified as Thaptic Hapludands and Typic Melanudands, while soils formed from volcanic tuff were classified as Andic Dystrudepts. The low bulk density and friable consistency of the soils contributed to favorable soil tilth. However, high P retention and Al saturation in most soils are limiting factors for plant growth. Application of P fertilizers and liming coupled with efficient placement can be recommended to enhance P availability and reduce Al toxicity. Organic matter can be used to reduce Al toxicity. Soil conservation needs to be considered, especially in the steep slope areas.

Continuous Corn and Corn–Soybean Profits over a 45‐Year Tillage and Fertilizer Experiment
Authors: Trlica Andrew , Walia Maninder K. , Krausz Ron , Secchi Silvia , Cook Rachel L. 
Published: October 2016

Core Ideas
Cumulative profit (1970–2014) in no‐till was similar to other tillage types with NPK.
Relative profits were more sensitive to changes in machinery than herbicide cost.
Return on fertilizer ranged from 56 to 251% for P and K and 69 to 434% for N.
Studies comparing profitability of tillage systems often examine narrow historic windows or exclude annual price fluctuations. This study uses a continuous corn (Zea mays L.) (CC; 1970–1990) and corn–soybean [Glycine max (L.) Merr.] (CS; 1991–2014) Tillage × Fertilizer study in somewhat poorly drained soils in southern Illinois to reconstruct partial annual budgets with historical prices for crops, fertilizers, lime, herbicides, fuel, labor, and machinery. Combinations of tillage (moldboard plow [MP], chisel tillage [ChT], alternate tillage [AT], and no‐till [NT]) and fertilizer (Control, N‐only, N+NPK starter, NPK+NPK starter, and NPK broadcast) treatments were evaluated. The CC profits were highest in NPK‐applied treatments followed by N‐only and Control. The MP treatments were similar to ChT and more profitable than NT, while AT fell between. In CS, NPK‐applied treatments were similar regardless of tillage. Combined costs for herbicide, machinery, labor, and diesel were higher in MP and ChT systems than AT and lowest in NT, but were a small percentage of total costs (26.6, 26.0, 21.5, and 18.2%, respectively). Nitrogen fertilizer offered a return on investment of 396% in CC and 133% in CS while P & K returned 78% in CC and 109% in CS. Sensitivity analysis in CS showed that NT would be less profitable than MP if herbicide costs increased 850%. A 300% machinery cost increase would have made MP less profitable than NT. These findings suggest that since 1991 CS under NT carried the same potential for profit as other tillage systems under full fertility management.
Phyllochron Interval and Yield Response to Planting Date and Fertility in Wheat
Authors: Oakes Joseph , Heiniger Ronnie , Crozier Carl , Murphy Joseph , Wilkerson Gail 
Published: October 2016

Core Ideas
Selecting the proper planting date is crucial in managing early leaf and tiller development while managing temperature.
There is an ideal planting date each year that will vary based on weather conditions.
Starter fertilizer may be necessary in cold, wet years to stimulate tiller growth.
Early growth and fall tiller production are key to high yields.
An understanding of early leaf and tiller growth in wheat (Triticum aestivum L.) and its impact on yield is an important concept for managing winter wheat. Field trials consisting of two planting dates (November and December) and three starter fertilizer treatments (urea ammonium nitrate, ammonium phosphate, Nachurs 9–18–9 liquid fertilizer) were conducted at four locations in North Carolina over a 2‐year period. The earlier planting dates resulted in the highest yield in 2013 to 2014, while the later planting date resulted in the highest yield in 2012 to 2013. Higher yield at the later planting dates in 2012 to 2013 was due to extremely cold weather and less than ideal growing conditions in November that increased the initial phyllochron interval (PI) of the early‐planted wheat. In contrast, ideal growing conditions in December coupled with warm winter weather resulted in a shorter average PI for wheat planted in December than for wheat planted in November. Despite a similar pattern with shorter initial PI at the later plantings in 2013 to 2014, the winter was not as warm and growing degree‐days (GDD) were not accumulated as rapidly as in the previous year, which limited the time that the later planting date had to develop leaves. A response to starter fertilizer was observed at one location in 2013 to 2014, resulting in a shorter PI and higher tiller counts with urea ammonium nitrate and 9–18–9 compared with the control. This resulted in an increased yield, and was largely due to abundant rainfall. This study indicates that planting date and starter fertilizer can influence the length of the initial PI and, depending on subsequent weather, can influence wheat yield.
A GIS‐based Upscaling Estimation of Nutrient Runoff Losses from Rice Paddy Fields to a Regional Level
Authors: Sun Xiaoxiao , Liang Xinqiang , Zhang Feng , Fu Chaodong 
Published: October 2016

Nutrient runoff losses from cropping fields can lead to nonpoint source pollution; however, the level of nutrient export is difficult to evaluate, particularly at the regional scale. This study aimed to establish a novel yet simple approach for estimating total nitrogen (TN) and total phosphorus (TP) runoff losses from regional paddy fields. In this approach, temporal changes of nutrient concentrations in floodwater were coupled with runoff‐processing functions in rice (Oryza sativa L.) fields to calculate nutrient runoff losses for three site‐specific field experiments. Validation experiments verified the accuracy of this method. The geographic information system technique was used to upscale and visualize the TN and TP runoff losses from field to regional scales. The results indicated that nutrient runoff losses had significant spatio‐temporal variation characteristics during rice seasons, which were positively related to fertilizer rate and precipitation. The average runoff losses over five study seasons were 20.21 kg N ha−1 for TN and 0.76 kg P ha−1 for TP. Scenario analysis showed that TN and TP losses dropped by 7.64 and 3.0%, respectively, for each 10% reduction of fertilizer input. For alternate wetting and drying water management, the corresponding reduction ratio was 24.7 and 14.0% respectively. Our results suggest that, although both water and fertilizer management can mitigate nutrient runoff losses, the former is significantly more effective.Core Ideas
A new model based on GIS was used to estimate regional nutrient runoff losses from paddy fields.
Regional variation of nutrient runoff losses was influenced by rainfall and fertilizer application.
Increasing floodwater storage is more advisable than fertilizer reduction to reduce nutrient runoff losses.
Effects of Dolomitic Limestone Application on Zinc Speciation in Boreal Forest Smelter‐Contaminated Soils
Authors: Hamilton Jordan G. , Farrell Richard E. , Chen Ning , Reid Joel , Feng Renfei , Peak Derek 
Published: October 2016

Anthropogenic activities at the HudBay Minerals, Inc., Flin Flon (Manitoba, Canada) mining and processing facility have severely affected the surrounding boreal forest ecosystem. Soil contamination occurred via a combination of metal and sulfuric acid deposition and has resulted in forest dieback and ineffective natural recovery. A community‐led effort to revegetate areas of the landscape through the application of a dolomitic limestone has been met with varied success. Zinc (Zn) speciation has shown to be closely linked to the presence or absence of an invasive metal‐tolerant grass species, with soils being broadly classed into two revegetation response groups. Group I, characterized by the absence of metal‐tolerant grasses, and group II, characterized by the presence of metal‐tolerant grasses. The systematic approach used to lime areas of the landscape produced a liming chronosequence for each group. This study used a combination of X‐ray absorption spectroscopy, X‐ray fluorescence mapping, and X‐ray diffraction techniques to determine the effect of liming on Zn speciation in these chronosequences. Liming group I soils resulted in the formation of a neo‐phase Zn‐Al‐hydroxy interlayer coprecipitate and subsequent rapid boreal forest revegetation. The effect of liming on Zn speciation on the group II soils resulted in a gradual transition of increasingly stable adsorption species, culminating with a stable Zn‐Al‐layered double hydroxide precipitate. Boreal forest vegetation has failed to recolonize group II soils during the study. However, the formation of the layered double hydroxide species resulted in a significant reduction in CaCl2–extractable Zn. Further research is required to determine how to promote the revegetation of these soils.Core Ideas
For sites where metal‐tolerant grass is absent, liming produces a limited pH response.
For sites where metal‐tolerant grass is present, liming has a larger pH effect.
Liming metal‐tolerant grass vegetated soils fails to promote boreal vegetation growth.
Zn‐Al‐HIM precipitates after liming soils where metal‐tolerant grass is absent.
Liming soils with metal‐tolerant grass transforms octahedral adsorbed Zn to Zn‐Al‐LDH.
Joaquín Giménez y El Tío Nonilla
Authors: Bonilla Reyna Helia Emma 
Published: October 2016

El desentrañamiento gradual de los múltiples procesos que convergen en la caricatura decimonónica mexicana permitirá construir interpretaciones fundamentadas de este tipo de imágenes. Se sabe poco sobre la regularidad de su circulación, sus autores, las motivaciones bajo las que actuaron, incluso sobre el sentido básico de sus imágenes. En estos aspectos encontramos algunas respuestas en El Tío Nonilla, uno de los periódicos mexicanos más tempranos en que se recurre a un uso abundante de la caricatura, y que se publicó a mediados del siglo xix en la ciudad de México. Su redactor en jefe e ilustrador, el inquieto escritor español Joaquín Giménez, fue un hombre de lengua e ingenio agudos, cuya actuación causó polémica en el medio periodístico capitalino. Los vaivenes en su postura reflejan, además de sus desavenencias personales, el estado efervescente de la política nacional; ello y la riqueza cultural de su tiempo se plasman tanto en sus caricaturas como en sus escritos.
Ciencia y arte en dos publicaciones astronómicas novohispanas del siglo XVIII
Authors: Moreno Corral Marco Arturo 
Published: October 2016

En 1769 ocurrieron varios fenómenos astronómicos que fueron observados desde la ciudad de México. José Antonio Alzate Ramírez fue uno de los que los estudió y la información que obtuvo la publicó en dos hojas sueltas ilustradas con grabados. Una de ellas muestra una muy bien lograda imagen de las casas del cabildo o ayuntamiento de la ciudad de México. En la actualidad esos documentos, que son valiosos desde el punto de vista estético y astronómico, son práctica-mente desconocidos. Por la información que contienen y por su belleza, nos hemos interesado en su estudio y en su rescate, pues sin duda son una clara muestra de la actividad científica que se desarrolló en el México del siglo XVIII, así como de la calidad alcanzada por los grabadores que entonces había en nuestra nación. Este trabajo también aporta nueva información sobre el edificio colonial que actualmente ocupa el Departamento del Distrito Federal en el extremo suroeste de la Plaza de la Constitución de la capital del país.
450 Tears Too Soon: Mixteca-Puebla Style Polychrome Ceramics in El Salvador
Authors: Amaroli B. Paúl E. , Olsen Bruhns Karen 
Published: October 2016

El Posclásico temprano en El Salvador se caracteriza por la fase Cihuatán, una versión local de la cultura de la elite internacional del Posclásico en Mesoamérica. Elementos de esta cultura, adoptada por los salvadoreños, incluyen urbanismo y estilos internacionales, mexicanizados, de arquitectura y de la planeación de centros rituales y de la elite, así como marcados cambios en el decorado de las céramicas. Entre los nuevos objetos de cerámica se encuentra Banderas polícroma, una versión local de la extendida tradición cerámica conocida como Mixteca-Puebla polícroma. La única muestra excavada por fechar es del mismo Cihuatán y corresponde en su mayoría con el subestilo del códice, un estilo que representa motivos del centro y sur de México cercanamente relacionados con las pinturas de los códices. Estos motivos son, en su mayoría, bélicos. Uno de los más comunes es el chimalli, o escudo, usualmente atado con dardos y atlatls, seguido de cráneos, huesos, partes del cuerpo desmembradas, espinas de maguey y otros arte-factos asociados con la guerra y el sacrificio.
Después de las utopías, la nostalgia. El siglo XIX y su recepción en el siglo XX
Authors: Dorotinsky Alperstein Deborah 
Published: October 2016

Este artículo propone una reflexión sobre la historiografía de la fotografía decimonónica como empezó a realizarse en el siglo XX. Aborda dos libros de Enrique Fernández Ledesma para analizar las formas de representación textual y visual de la experiencia burguesa en el siglo XIX, en particular la romántica. Resalta la importancia que tuvieron las construcciones de comportamientos de clase social y de género pensando en la complementariedad de la dupla tradición/modernidad como una tensión casi inescapable en la construcción de una modernidad nacional. Por ello se vinculan con los sueños utópicos y las remembranzas del pasado tanto virreinal como decimonónico. Es decir una nostalgia del pasado como actitud histórica, como una expresión más de lo paradójicas que fueron las energías que movieron la cultura después del renacimiento cultural de la posrevolución y de las formas de irse dando la modernidad en el país.
La cruz mexicana del siglo XVI de la catedral de Palencia (España): la visión indígena del Gólgota como "la montaña sagrada"
Authors: García Barrios Ana , Parada López de Corselas Manuel 
Published: October 2016

En este estudio se analiza la cruz de altar de cristal de roca y plata dorada que se conserva en la catedral de Palencia (España). La obra mide 48,5 cm de altura y consta de dos partes: la cruz propiamente dicha con su Cristo crucificado y, en la cruceta, una representación de Dios Padre en la parte delantera y la Virgen en la posterior; la segunda parte, que sirve de apoyo a la cruz, se trata de una representación del Gólgota o Calvario habitado por diversas plantas y animales de clara tradición prehispánica mesoamericana. Su base contiene la marca de la ciudad de México empleada al menos desde mediados del siglo XVI hasta ca. 1572. Dentro del arte novohispano esta cruz se incluye estilística e iconográficamente entre las primeras manifestaciones del llamado arte indocristiano. Pese a ello, solamente figura en publicaciones sobre platería virreinal novohispana y su complejo programa hasta ahora no se había estudiado a profundidad. iconográfico

"Trampantojo a lo divino": El Nazareno del Hospital de Jesús en Pensilvania
Authors: Robin Alena 
Published: October 2016

En la segunda mitad del siglo xvii una indígena donó una escultura de Jesús Nazareno a la iglesia del Hospital de la Concepción de Nuestra Señora de la ciudad de México. A los pocos años, el culto adquirió proporciones mayores, a tal punto que el nombre del hospital cambió por el de Hospital de Jesús, con el cual todavía se le conoce. A medida que el culto del Nazareno fue creciendo, también lo hizo el fenómeno de las "copias", en el cual una efigie, por el respeto y devoción que había adquirido, se transformaba en "modelo" a seguir. El propósito de esta noticia es dar a conocer un cuadro novohispano, conservado en el St. Charles Borromeo Seminary, en Wynnewood, Pensilvania, y explicar porqué se cree que dicha pintura es un retrato pintado de esta devota escultura.

Background This study aimed to determine the effect of tenofovir disoproxil fumarate (TDF) on bone metabolism and bone mass in HIV-infected adolescents. Methods This was a sub-study of a cross-sectional multicentre bone health trial that enrolled perinatally HIV-infected Thai and Indonesian adolescents (10–18 years) with viral suppression on antiretroviral therapy. Participants were classified into two groups as TDF users and non-users. Bone metabolism-related markers (25-hydroxyvitamin D [25-OHD], intact parathyroid hormone [iPTH], bone turnover biomarkers), and lumbar spine dual-energy X-ray absorptiometry were assessed. Bone mineral density (BMD)/bone mineral apparent density (BMAD) Z-scores were calculated. Results Of 394 adolescents, 136 (34.5%) and 258 (65.5%) were TDF users and non-users, respectively. Among TDF users, median age (IQR) was 16.1 (14.7–17.4) years and TDF treatment duration (IQR) was 2.3 (1.4– 3.1) years. Among TDF non-users, median age (IQR) was 14.3 (12.6–16.4) years. BMD and BMAD Z-scores comparing TDF users with non-users were -0.8 and -0.6 ( P=0.27), and -0.3 and -0.2 ( P=0.58), respectively. The association between TDF use and iPTH elevation was intensified in adolescents with suboptimal vitamin D levels (25-OHD <30 ng/ml; P=0.001). TDF administration was positively associated with bone resorption marker ( P=0.04) and negatively associated with bone formation marker ( P=0.04). With data up to 4 years, neither association between TDF use and bone mass loss (BMD: P=0.09; BMAD: P=0.22), nor variation of bone mass Z-scores by TDF treatment duration (BMD: P=0.34; BMAD: P=0.58) was demonstrated. Conclusions Recent TDF administration was correlated with PTH elevation and bone turnover dysregulation but not with bone mass reduction in our cohort. A study with extended follow-up to ascertain TDF-associated bone mass deterioration is warranted.
Crime organisé : un acteur global
Authors: Roudaut Mickaël R. 
Published: October 2016

Si les trafics ont toujours existé, ils ont développé une dimension transnationale dans le sillage de la mondialisation. Loin de représenter des réalités éthérées, les flux illicites exercent une influence réelle sur les relations internationales. Ils revêtent donc une portée géopolitique globale. À l’échelle locale, les acteurs de ces flux illicites, du grand criminel à la « petite frappe », incarnent, en remettant en cause la légitimité des États, un modèle alternatif de développement. In fine , le crime organisé, parfois seul employeur viable au sein de régions pauvres ou en déshérence, effectue un saut qualitatif dépassant une nature simplement parasitaire au profit d’une relation symbiotique avec le pouvoir.
