El dilema de la Reforma Tributaria: ¿estructural o fiscalista?
Authors: Vallejo Zamudio Luis Eudoro 
Published: February 2017

El 20 de octubre, el ministro de Hacienda, Mauricio Cárdenas, presentó ante el Congreso el proyecto de Ley de Reforma Tributaria, cuyo fundamento, en buena parte, es el informe de la Comisión de Expertos Tributaristas. El Gobierno nacional aspira a recaudar $7.2 billones y, de esta forma, compensar la reducción de los ingresos de la nación provocados por factores tales como la caída de los precios del petróleo, la reducción del crecimiento económico, que -de acuerdo con proyecciones para 2016 del Banco de la República, puede ser de alrededor del 2 %-, y la eliminación de impuestos temporales a partir del 2018.
Vocabularies of Citizenship: West Coast Secondary Students Describe Their Civic Subjectivities, Skills, and Classrooms
Authors: Elbert Jamie 
Published: February 2017

Canada’s changing geopolitical landscape will require a generation of engaged and active citizens. Citizenship education in British Columbia must negotiate conflicting narratives while opening spaces for students to develop civic skills and subjectivities. Given negative program reviews, empirical evidence for the impact of identity - especially group identifications - on behaviours and beliefs, and continued low youth political engagement, there is a great need to understand how citizenship and civic subjectivities are constructed in real school contexts in order to gain insight into how secondary civics classrooms might support students’ active political voices and development of efficacious subjectivities.	This article reports preliminary results from a large mixed methods, multiple-case study project. The data reported here focuses on students (n = 64) from two purposefully sampled secondary school classrooms on Vancouver Island: a special civics program, and a regular stream Social Studies classroom in the same school. Data collection consisted of a class-wide online survey near the beginning of the course. Grounded in the larger understandings of social identity theory and rooted cosmopolitanism, qualitative data from open-ended questionnaire responses analyzed with a constant comparative coding technique explored the extent to which students construct regional, national, or global notions of citizenship. A preliminary report of quantitative items investigates the level of conflict present between levels of identification and suggests avenues for future research. Examined against previous research and the theory of rooted cosmopolitanism, this project aims to question the popular narrative of youth apathy and to describe the ways in which students characterize their civic subjectivities. In giving voice to student perspectives on their civic selves and their Civics classrooms, this study aims to contribute to more representative classrooms and pedagogies.
Peanut Residue Carbon and Nitrogen Mineralization under Simulated Conventional and Conservation Tillage

Published: February 2017

Core Ideas
Recommendations of 22 to 67 kg N ha−1 credit after peanut are not substantiated.
Decomposition of peanut residue in North Carolina and Alabama fit double exponential decay equations.
Nitrogen credit to wheat was 14 to 24 kg N ha−1, but to cotton was 2 to 10 kg N ha−1.
Nitrogen credits differ by location and placement of residue.
Nitrogen credits should be specified to which crop they are applied.
Residue management is an important aspect of cropping systems. Availability of plant residue N to succeeding crops depends on N mineralization rates. Cooperative Extension currently recommends 22 to 67 kg N ha−1 credit to subsequent crops following peanut (Arachis hypogaea L.), but these recommendations are not supported in the literature, nor do they specify if the credit is applied to a subsequent winter or spring crop. The objective of this study was to assess N release rates from residues of three peanut cultivars (NC V‐11, GA 02‐C, and ANorden) at two placements (surface and 10‐cm deep) and two locations representing northern and southern extremes of U.S. commercial peanut production (North Carolina and Alabama). Litterbags containing the equivalent of 3.5 Mg ha−1 were placed in a completely randomized design at both locations with four replications and retrieved periodically up to 335 d after application. Results were fit to single or double exponential decay models. Based on empirical models, the N credit to a subsequent winter wheat (Triticum aestivum L.) crop was estimated at 14 to 19 kg N ha−1 when peanut residues were buried after harvest, and 19 to 24 kg N ha−1 when on the soil surface. When N credits were applied to a subsequent cotton (Gossypium hirsutum L.) crop, they were reduced to 2 to 9 kg N ha−1 (buried) and 6 to 10 kg N ha−1 (surface). Current recommendations are higher than the results obtained in this study suggest and warrant re‐examination.

Core Ideas
Forage radish and winter pea cover crops improved nitrogen‐use efficiency in a potato cropping system.
A high N‐yielding winterkilled cover crop is preferred over rye for early planting of potato.
Rye may not provide the succeeding potato with sufficient N because of early termination.
Growers in the northeastern United States often over‐apply N fertilizer to guard against yield limitations. Over fertilization increases costs of production and raises environmental concerns. This study was conducted to evaluate whether using cover crops and N fertilizer management can improve tuber yield and nitrogen‐use efficiency (NUE) in a potato (Solanum tuberosum L.) production system. Three cover crop species including forage radish (Raphanus sativus L.), cereal rye (Secale cereale L.), and winter pea (Pisum sativum L.); four N fertilizer rates (0, 75, 150, and 225 kg N ha−1) and two potato varieties (Dark Red Norland [DRN] and Superior [SUP]) were used in a 2‐yr field experiment. Results indicated that tuber yield and NUE indices can be restricted by either the lowest or highest levels of N fertilizer (75 and 225 kg N ha−1, respectively). Potato grown in no cover crop plots needed to be fertilized at 225 kg N ha−1 to produce the highest yield (26.5 Mg ha−1) whereas potato after winter pea or forage radish produced the same or higher yields at 75 and 150 Kg N ha−1, respectively (P ≤ 0.01). Forage radish or winter pea improved NUE in either potato variety as more synchrony existed with respect to N release from cover crop residues and potato N requirements than that of cereal rye. Overall, forage radish or winter pea could be suitable alternatives to cereal rye in rotation with potato as indicated by the cover crop biomass production and N yield, N use metrics, and potato tuber yield.

Core Ideas
Soybean in organic no‐till yielded as well as conventional organic.
Corn in organic no‐till had lower yield than conventional organic.
A crimped cover crop can cause N immobilization and reduced corn yield.
Organic crop production is dependent on tillage for weed control, but because tillage can lead to decreased levels of soil organic carbon (SOC) alternative management needs to be explored. This study was conducted in Boone County, Missouri, in 2012 to 2014 to determine the effects of three organic production systems and four poultry compost rates on crop yield and SOC on a claypan soil. The production systems included tillage with no cover crop, tillage with a mowed and incorporated cover crop, and no‐till with a crimped cover crop in a wheat (Triticum aestivum L.)–corn (Zea mays L.)–soybean (Glycine max L.) rotation. Cover crops included cereal rye (Secale cereale L) and hairy vetch (Vicia villosa L.). Compost rates were 0, half the recommended rate, the recommended rate, and 1.5 times the recommended rate. Achieving cover crop biomass sufficient for weed suppression was a challenge when soil fertility declined during the study. Corn yield was reduced 30% in 2013 in no‐till plots compared to tilled although plant populations were nearly equal, indicating that N immobilization may be significant in crimped cover crops. When there was adequate soil moisture and weed control from the cover crop, soybean grown under organic no‐till was competitive with tilled treatments. Optimum timing of cover crop crimping for acceptable weed control was more successful in a soybean system compared with corn. Organic no‐till in this study was more successful in soybean and wheat than in corn, when the cover crop biomass was sufficient to suppress weeds.
Major ions behaviour during evaporation of different saline type water of Western Mongolian lakes (geochemical modelling)
Authors: Kolpakova Marina N. , Gaskova Olga L. 
Published: February 2017

AbstractThe main Mongolian water resources are lakes whose volume has significantly reduced in recent years as a consequence of global warming. This article presents research on three different types of nearly disposed Western Mongolian lakes with a wide range of brines’ composition: Shaazgai-Nuur (soda), Davsan-Nuur (chloride) and Tonhil-Nuur (sulfate). The aim of this study was to determine the differences in geochemical evolution associated with evaporation-crystallization processes of representative lakes of various chemical types. The modelling was performed by using PHREEQC and HCh software that allows application of Pitzer's approach for saline solutions. The modelling was performed for these natural objects for the first time. The model demonstrated that the evaporation-crystallization processes are different for soda and chloride/sulfate brines. Soda type lake maintained unchanged ion composition while chemical composition of chloride and sulfate lakes went through significant alterations according to a sequence of mineral precipitation. The calculated model did not confirm the possibility of long-term transformation from SO4-Mg brines to Cl-Mg due to evaporative concentration only; additional factors including mixing with inflow water also influence sodium and chloride increase. Close agreement between the model and the actual mineralogical data was observed, testifying to the proper software and reliability of our assumptions.
Cardiomyocyte Reprogramming: A Potential Strategy for Cardiac Regeneration
Authors: Tendean Marshel , Oktaviono Yudi Her , Sandra Ferry 
Published: February 2017

Heart disease is the leading cause of death worldwide. Within decades a limited process of cardiac cell regeneration was under observation. Embryonic stem cell (ESC) shows great potential for cell and tissue regeneration. Studies indicate that ESC has the potential to enhance myocardial perfusion and/or contractile performance in ischemic myocardium. However there is still challenge to evaluate the issues of teratoma. Then induced pluripotent stem cell was invented by introducing four transcriptional factors (Oct4, Sox2, Klf4, c-Myc). iPSC was created from murine fibroblast and then differentiated into cardiomyocyte. Reprogramming the adult cell could be performed in full, partial or direct reprogramming. Several studies add the significance by reprogramming the cells through more efficient techniques. However several limitations are still remained.Keywords: cardiomyocyte, reprogramming, iPSC, fibroblast

Identificación de especies del género Ischnosiphon utilizadas por dos comunidades Ticuna del Perú para elaborar sus tejidos tradicionales
Authors: Martín Brañas Manuel , Núñez Pérez Cecilia Del Carmen , Zárate Gómez Ricardo 
Published: February 2017

El pueblo ticuna ha ocupado desde tiempos ancestrales el territorio que comprende actualmente la triple frontera entre Brasil, Colombia y Perú, manteniendo, a través de los años y a pesar de la separación limítrofe, ciertos vínculos sociales y culturales, fortalecidos a través del intercambio de saberes y prácticas culturales. En el Perú existe una escueta bibliografía etnobiológica sobre los usos tradicionales que los ticuna dan a las especies vegetales de su entorno, a diferencia de lo que ocurre en Colombia y Brasil. En ese sentido se llevó a cabo una investigación para identificar las especies del género <em>Ischnosiphon, </em>utilizadas tradicionalmente por dos comunidades ticuna de la cuenca baja del río Amazonas para elaborar sus tejidos utilitarios y rituales. Las comunidades de estudio fueron Bufeo Cocha y Santa Rita de Mochila, ubicadas en el Distrito de Ramón Castilla, Provincia de Mariscal Ramón Castilla, en el Departamento de Loreto (Perú). La investigación permitió determinar el sistema de uso tradicional de las especies del género <em>Ischnosiphon</em>, localmente conocidas como huarumá. Se determinaron tres especies utilizadas por estas comunidades en sus tejidos tradicionales, realizándose la identificación taxonómica de las mismas (<em>I. arouma, I. obliquus, I. puberulus</em>) y registrándose el uso que los ticuna del bajo Amazonas dan a las fibras extraídas de sus tallos.
