Published: October 2017

As the main gas production layer, the subsalt Cretaceous Bashijiqike Formation of Kuqa foreland basinis charactered by large depth and poor matrix properties. Structural fractures are widespread with complicated characteristics and distribution, which have large influence on gas production. A lot of effort has been put into the research on the fracture in this area, the research includes refined fracture description on the basis of core and image log data; multi-methods and multi-times fracture distribution pattern prediction. However, the above studies are limited by core availability, seismic data quality, well log data, etc, so the fracture prediction results were not good. Considering the fractures of super-deep tight sandstone reservoirin Kelasu structural belt having the characteristics of multiscale, and the development characteristics, origin and distribution pattern of fractures with different sizes being different, this study defined fracture classes, systematically summarized the development characteristics and distribution patterns of fractures at different scales and their groups, and explored the control effect of fracture system on reservoir. The following understandings are obtained: (1) based on fracture length, aperture, development characteristics, etc, fractures are divided into three classes, namely first order fracture – large fractures, second order fracture – grain penetrating fractures, third order fracture – grain margin fractures; (2) based on fracture length, origin, and combination characteristics, three classes of fracture combinations are recognized, namely first order fracture combination – dominant fracture belt; second order fracture combination – dominant fractures and associated fractures; third order fracture combination – grain margin fracture network; (3) fractures are the main flowing channel in superdeep tight sandstone reservoir, fractures effectively improved reservoir flow property and act as the main contributor of high and stable production in low porosity sandstone reservoir.

Conventional approach to project exploration strategy planning at Identification/Access stage is usually focused on hydrocarbon presence confirmation and uncertainties decreasing. Further, at the end of the Appraisal stage, the main purpose is creating successful business case. However, focus on economic value of total project at Identification stage may lead to more optimal exploration program and increasing project EMV.

The objective of this case study is to describe specific approach to establish major project exploration strategy at initial stage, based not only on uncertainty decreasing, but also on early business case development and maximizing future economic value.

Case study project is framed within license area in the north-eastern part of the Pannonian Basin of Eastern Europe. 2D seismic survey identified 41 structural, structural-tectonic and pinch-out traps.

Specific methodology, applied to this project, consists of 3 key steps.

At first, full-cycle business case design and calculation were performed. All defined traps were rated by complex geological criteria: geological chance of success, probabilistic STOIIP estimation etc. Then production profiles were estimated for each prospect in accordance with P90, P50, P10 STOIIP outcomes. Preliminary surface facilities concept was developed and tied to expected markets, which were revealed after detailed region investigation and analysis of logistic and transport options. The whole project life cycle CAPEX and OPEX were estimated corresponding to P90, P50, P10 production profiles. Economic value (EMV, J) of each prospect and the whole business case were calculated and allowed to specify initial prospects rating.

Next step is optimization calculations, which revealed synergy potential of possible clustering of prospects.

At last, total rating of most valuable traps is formed. The most important issue of exploration strategy is not only list of rated options but also timing, sequence of works, geological and non-technical risk estimation.

As a result, exploration strategy included 10 traps, optimized 3D seismic and exploration drilling schedule, and key decision to drill exploration wells for the specific traps without 3D seismic. Preliminary optimal facilities concept was revealed as placement of 5 wells per separate platform with integrated oil preparation facilities and in-house energy generation.

Published: October 2017

The dewaterability of excess sludge significantly improved upon pretreatment with Fenton's reagent in this study. After 0.9 g/L of Fe2+ and 5.0 g/L of H2O2 were added to the sludge, and reacted for 2 h at pH = 4, the specific resistance to filtration (SRF) of the excess sludge decreased from an initial value of 29.74 × 1012 m/kg to 6.49 × 1012 m/kg. The factors that affected this improvement in sludge dewaterability as evaluated by SRF reduction showed the following order: H2O2 > pH > Fe2+ > reaction time. Furthermore, the hydrolysis performance of the sludge under the optimal reaction conditions was investigated. The results indicated that the concentration of soluble chemical oxygen demand in the supernatant increased almost 14 times compared to raw sludge, and the contents of soluble protein and soluble polysaccharide were more than 8 and 17 times higher, respectively, than for the untreated situation. However, the amounts of ammonia nitrogen (NH4+-N) and phosphate (PO43−-P) released from the sludge showed different trends: NH4+-N increased by 200%, while PO43−-P decreased by 82%. The production of volatile fatty acids (VFAs) from the treated sludge showed that total VFAs increased by 66%, and iso-butylacetic acid was the dominant product among the total VFAs.
The Research on Influence of Unloading on Borehole Stability in Clay-Rich Shale Formation
Authors: Ding Yi , Liu Xiangjun , Luo Pingya , Liang Lixi
Published: October 2017

Introduction:

Unloading phenomenon happens in the beginning of drilling and is able to change stress state around borehole. This change of stress state causes impact on rock structure and strength, thus affecting the evaluation of wellbore stability. Especially for determining initial mud pressure, unloading is a significant influence factor. Clay-rich shale formation is well-known for high risk of borehole collapsing, appropriate mud pressure is necessary to stabilize wellbore. Therefore, the unloading influence needs to be considered when it comes to selection of initial mud pressure.

Materials and Methods:

In this paper, based on the triaxial test, unloading situation has been simulated to investigate the influence of unloading on rock mechanical property. It is shown that clay-shale strength declines with increasing unloading range. Also, note that in comparison with internal friction angle, cohesion has larger decline caused by unloading.

Results:

Taking account of the unloading influence, new model has been established to investigate wellbore stability. These results demonstrate that unloading creates variable strength decrease at the wall of borehole due to different in-situ stress and well trajectory. This strength decrease gives rise to increasing collapse pressure. In particular, unloading has relatively larger impact in the formation with strong anisotropy and high in-situ stress. Besides, inappropriate well trajectory will increase unloading impact.

Conclusion:

Finally, this model has been applied to several cases in clay-shale formation, Northern China. And the new model in each case is well consistent with oilfield experience, indicating its practicability and proving unloading is a non-negligible factor for the assessment of wellbore stability.
High Octane Gasoline Using Renewable Aromatic Hydrocarbons
Authors: Seames Wayne , Khambete Malhar , Khatibi Nahid , Amsley-Benzie Shelby , Kozliak Evguenii , Muggli Darrin , Tande Brian
Published: October 2017

Background:

The replacement of leaded high octane aviation gasoline with an unleaded renewable alternative would decrease the emissions of lead and fossil-derived carbon into the atmosphere. Replacement has been limited by the requirement of a very high octane number in many existing general aviation aircraft engines.

Method:

Two separate process pathways were developed that generate an unleaded octane fuel with a motor octane number >96 from triglyceride oils (TGs), such as crop oils and algae oil. A series of experiments coupled with process simulations was used to verify the feasibility of both pathways and to provide preliminary laboratory scale data that could form the basis for further development towards a commercial technology. In the first pathway, TG oil is catalytically cracked to produce a high concentration of simple aromatic hydrocarbons. These aromatic hydrocarbons are then alkylated using propylene to form a mixture, which after purification acquires fuel properties compliant with those in the ASTM specification for 100 octane low lead aviation gasoline (100LL AvGas). In the second process pathway, the aromatic hydrocarbons are isolated after cracking using a sulfolane solvent extraction process to increase alkylation efficiency and fuel quality.

Result:

The results demonstrate that it is technically feasible to produce a replacement for 100LL AvGas using either pathway, and thus these strategies may be attractive candidates for commercialization.

Leveraging Self-Affirmation to Improve Behavior Change: A Mobile Health App Experiment (Preprint)
Authors: Springer Aaron , Venkatakrishnan Anusha , Mohan Shiwali , Nelson Lester , Silva Michael , Pirolli Peter
Published: October 2017

BACKGROUND

mHealth interventions can help to improve the physical well-being of participants. Unfortunately, mHealth interventions often have low adherence and high attrition. One possible way to increase adherence is instructing participants to complete self-affirmation exercises. Self-affirmation exercises have been effective in increasing many types of positive behaviors. However, self-affirmation exercises often involve extensive essay writing, a task that is not easy to complete on mobile platforms.

OBJECTIVE

This study aimed to adapt a self-affirmation exercise to a form better suited for delivery through a mobile app targeting healthy eating behaviors, and to test the effect of differing self-affirmation doses on adherence to behavior change goals over time.

METHODS

We examined how varied self-affirmation doses affected behavior change in an mHealth app targeting healthy eating that participants used for 28 days. We divided participants into the 4 total conditions using a 2×2 factorial design. The first independent variable was whether the participant received an initial self-affirmation exercise. The second independent variable was whether the participant received ongoing booster self-affirmations throughout the 28-day study. To examine possible mechanisms through which self-affirmation may cause positive behavior change, we analyzed three aspects of self-affirmation effects in our research. First, we analyzed how adherence was affected by self-affirmation exercises. Second, we analyzed whether self-affirmation exercises reduced attrition rates from the app. Third, we examined a model for self-affirmation behavior change.

RESULTS

Analysis of 3556 observations from 127 participants indicated that higher doses of self-affirmation resulted in improved adherence to mHealth intervention goals (coefficient 1.42, SE 0.71, P=.04). This increased adherence did not seem to translate to a decrease in participant attrition (P value range .61-.96), although our definition of attrition was conservative. Finally, we examined the mechanisms by which self-affirmation may have affected intentions of behavior change; we built a model of intention (R2=.39, P<.001), but self-affirmation did not directly affect final intentions (P value range .09-.93).

CONCLUSIONS

Self-affirmations can successfully increase adherence to recommended diet and health goals in the context of an mHealth app. However, this increase in adherence does not seem to reduce overall attrition. The self-affirmation exercises we developed were simple to implement and had a low cost for both users and developers. While this study focused on an mHealth app for healthy eating, we recommend that other mHealth apps integrate similar self-affirmation exercises to examine effectiveness in other behaviors and contexts.

Authors: Pascoe Michael , Monroe Forrest , Macfarlane Helen
Published: October 2017

BACKGROUND

Wiki platform use has potential to improve student learning by improving engagement with course material. A student-created wiki was established to serve as a repository of study tools for students in a medical school curriculum. There is a scarcity of information describing student-led creation of wikis in medical education.

OBJECTIVE

The aim is to characterize website traffic of a student-created wiki and evaluate student perceptions of usage via a short anonymous online survey.

METHODS

Website analytics were used to track visitation statistics to the wiki and a survey was distributed to assess ease of use, interest in contributing to the wiki, and suggestions for improvement.

RESULTS

Site traffic data indicated high usage, with a mean of 315 (SD 241) pageviews per day from July 2011 to March 2013 and 74,317 total user sessions. The mean session duration was 1.94 (SD 1.39) minutes. Comparing Fall 2011 to Fall 2012 sessions revealed a large increase in returning visitors (from 12,397 to 20,544, 65.7%) and sessions via mobile devices (831 to 1560, 87.7%). The survey received 164 responses; 88.0% (162/184) were aware of the wiki at the time of the survey. On average, respondents felt that the wiki was more useful in the preclinical years (mean 2.73, SD 1.25) than in the clinical years (mean 1.88, SD 1.12; P<.001). Perceived usefulness correlated with the percent of studying for which the respondent used electronic resources (Spearman ρ=.414, P<.001).

CONCLUSIONS

Overall, the wiki was a highly utilized, although informal, part of the curriculum with much room for improvement and future exploration.

Authors: Bose-Brill Seuli , Feeney Michelle , Prater Laura , Miles Laura , Corbett Angela , Koesters Stephen
Published: October 2017

BACKGROUND

Advance care planning allows patients to articulate their future care preferences should they no longer be able to make decisions on their own. Early advance care planning in outpatient settings provides benefits such as less aggressive care and fewer hospitalizations, yet it is underutilized due to barriers such as provider time constraints and communication complexity. Novel methods, such as patient portals, provide a unique opportunity to conduct advance care planning previsit planning for outpatient care. This follow-up to our pilot study aimed to conduct pragmatic testing of a novel electronic health record-tethered framework and its effects on advance care planning delivery in a real-world primary care setting.

OBJECTIVE

Our intervention tested a previsit advance care planning workflow centered around a framework sent via secure electronic health record-linked patient portal in a real-world clinical setting. The primary objective of this study was to determine its impact on frequency and quality of advance care planning documentation.

METHODS

We conducted a pragmatic trial including 2 sister clinical sites, one site implementing the intervention and the other continuing standard care. A total of 419 patients aged between 50 and 93 years with active portal accounts received intervention (n=200) or standard care (n=219). Chart review analyzed the presence of advance care planning and its quality and was graded with previously established scoring criteria based on advance care planning best practice guidelines from multiple nations.

RESULTS

A total of 19.5% (39/200) of patients who received previsit planning responded to the framework. We found that the intervention site had statistically significant improvement in new advance care planning documentation rates (P<.01) and quality (P<.01) among all eligible patients. Advance care planning documentation rates increased by 105% (19/39 to 39/39) and quality improved among all patients who engaged in the previsit planning framework (n=39). Among eligible patients aged between 50 and 60 years at the intervention site, advance care planning documentation rates increased by 37% (27/96 to 37/96). Advance care planning documentation rates increased 34% among high users (27/67 to 36/67).

CONCLUSIONS

Advance care planning previsit planning using a secure electronic health record-supported patient portal framework yielded improvement in the presence of advance care planning documentation, with highest improvement in active patient portal users and patients aged between 50 and 60 years. Targeted previsit patient portal advance care planning delivery in these populations can potentially improve the quality of care in these populations.

The objective of the research was to determine the effect of the germination of black rice. Black rice was soaked for 12 h and further germinated for 12, 24, 36, and 48 h. Non-germinated black rice was used as a control. Black rice was germinated for 19-20 h. Fat, and moisture content, total sugar, cooking quality, sensory analysis, and fatty acid composition of germinated black rice were further evaluated. Results show that fat content decreased during germination, but moisture content and total sugar increased. Physiochemical properties, such as length expansion ratio, volumetric expansion, water absorption, gel consistency, and alkali values were in the ranges of 0.77-0.91 mm, 2.42-3.38, 1.64-2.04, 66-82.5 mm, and 2-3.5, respectively. From sensory analysis, most of panelists were favorable for the germinated black rice at 24 h germination. SFA and MUFA tended to decrease during germination but PUFA tended to increase. Thus the germination is effective to improve nutritional values of black rice

Published: October 2017

Fermentation of peanut milk added with various sucrose concentrations using candidate probiotic strain of Lactobacillus paracasei SNP-2 was investigated, and the lactic acid bacteria survival during storage of the fermented peanut milk drinks were also studied. Peanut milk fermentations were carried out at 37°C for 18 h. It was found that peanut milk without addition of sucrose could support the growth of L. paracasei SNP-2, but not the production of lactic acid. Fermentation of peanut milk with addition of 2-10% sucrose significantly increased the production of lactic acid. The numbers of lactic acid bacteria showed no marked reduction in the fermented peanut milk drinks during storage at 4°C for 21 days, still sufficiently high to exert beneficial probiotic effects in the host. Fermented peanut milk drink using L. paracasei SNP-2 can be used as a non-dairy probiotic product.

Published: October 2017

The study’s aim was to develop a quantitative risk assessment model of Listeria monocytogenes in liver chicken paté. The model was performed using the Integrated Challenge Test (Italian Journal of Food Safety, Vol. 1 N. 6 2012) with the objective to reduce the analytical cost and time. The challenge test was carried out on 3 different batches stored at 12°C and inoculated with a mix of Listeria monocytogenes strains. Lactobacillus spp. and Listeria monocytogenes plate counts were performed daily on each sample until the stationary phase was reached by both populations. The challenge test results at 12°C were input in the Combase DMfit software to determine the growth parameters of Listeria monocytogenes and lactic flora which showed mutual interaction. Then, using the Combase Predictor for Listeria monocytogenes and the FSSP (Food Spoilage and Safety Predictor) software for lactic flora, the growth parameters were extrapolated at 4°C and 8°C. The growth parameters of both populations at 4°C, 8°C and 12°C were then used to apply the model in order to predict the maximum daily concentration of Listeria monocytogenes. Model results were assessed against the results of an additional challenge test conducted with the same strain mix inoculum in 3 different batches stored for 4 days at 4°C, 4 days at 8°C and then 4 days at 12°C. The proposed model represents a reliable quantitative risk evaluation which provides realistic results with limited cost.

El objetivo del estudio fue realizar un análisis de rentabilidad de la producción de maíz en el Distrito de Desarrollo de Tulancingo, Hidalgo. Se realizó una encuesta dirigida a 55 productores, considerando variables de carácter cuantitativo y cualitativo, de mayo a septiembre de 2010. Se identificaron tres categorías de productores según su rendimiento: categoría I: rendimiento £ 1 t ha-1, (24 % de los productores); categoría II: de 1.1 a 2 t ha-1, (72%) y categoría III: ≥ 2.1 (4%). Algunos de los problemas que enfrentaban eran: sequía (96% mencionó que la falta de agua limita la producción); reducido uso de semilla mejorada (28 % la utiliza); control fitosanitario deficiente (sólo 4 % lo realiza); 24 % aplica herbicidas; y 60 % fertiliza, evidenciando un bajo nivel tecnológico. Lo anterior, por la falta de asesoría técnica y capacitación. Los costos de producción promedio fueron de $7290.19 por ha, con un rendimiento de 1.87 t ha-1, lo que permite obtener ganancias de $83.15 por ha. Los productores de categoría III tienen una ganancia de $1067.80 por tonelada, mientras que los de categoría I registran pérdidas de $2416.50, lo que se explica por los bajos rendimientos.
Necesidades femeninas básicas y fugitivas de la política social, en comunidades productoras de maíz nativo.

Published: October 2017

El objetivo de este trabajo es conocer y analizar cómo las mujeres rurales redefinen sus necesidades ante la imposición de programas sociales diseñados para satisfacer las necesidades básicas femeninas, promover el avance de las mujeres pobres y desarrollar el bienestar de sus familias. El análisis parte de la analogía del contenedor, donde las necesidades son fluidos que toman la forma del recipiente que los contiene, y la tapa del contenedor son los programas sociales. El estudio se realizó con mujeres de dos comunidades que producen maíz nativo en el Estado de México y que han sido sujetas de programas sociales, al mismo tiempo que han vivido las consecuencias del retiro de los apoyos estatales a la producción de subsistencia. Los resultados muestran que estos programas sostienen los roles de reproducción asignados tradicionalmente a las mujeres rurales pero, frente a los cambios que traen consigo los procesos de globalización en la vida cotidiana de ellas, se puntualiza la existencia de pequeños escapes del contenedor, lo que se traduce en necesidades fugitivas, mismas que desafían la definición del Estado sobre las necesidades básicas femeninas.
La perspectiva de género en la comprensión de la masculinidad y la sobrevivencia indígena en México.
Authors: Díaz-Cervantes Rufino
Published: October 2017

Este trabajo propone un marco teórico para orientar la aprehensión de los matices patriarcales y heterosexistas de las masculinidades indígenas en México y Latinoamérica, cuyos contextos son la supervivencia y reproducción en condiciones de marginalización. Parte de reflexionar sobre algunos aportes de los estudios de género y de las masculinidades, en general de la academia feminista, que enfatizan sobre la perspectiva de género. Discute la importancia de abordar la relación existente entre etnia y género para entender procesos históricos que intervienen en la construcción del sujeto indígena contemporáneo y plantea la necesidad de superar al discurso de la dualidad de género en función de probar la existencia de la diversidad genérica, invisibilizada y reprimida por la vigencia de sistemas simbólicos, que evidencian particularidades de la masculinidad hegemónica y la dominación masculina indígenas. Se concluye que la interpretación de la masculinidad indígena requiere ser estudiada respecto a sus significados y prácticas originarias, sus resistencias y alianzas con las socializaciones occidentales, sus consecuencias para la sobrevivencia y reproducción indígena, particularizada en sus afectaciones a mujeres, hombres y en otras identidades genéricas reprimidas, además de advertir sus trascendencias en el medio ambiente.
¿Quién toma las decisiones agrícolas? Mujeres propietarias en el Ecuador.
Authors: Deere Carmen D. , Twyman Jennifer
Published: October 2017

Este trabajo investiga si las mujeres propietarias de parcelas participan en las decisiones agrícolas sobre ellas. Con base en una muestra nacional de Ecuador, el análisis demuestra que la gran mayoría de mujeres dueñas participan activamente en la conducción de sus parcelas, sean éstas propiedades de ellas de manera individual o en conjunto con su pareja. También revela que hay diferencias en el nivel de participación de las mujeres, dependiendo de su estado civil o situación marital (si son casadas o unidas en comparación con jefas de hogar solteras, separadas, divorciadas o viudas) y de la forma de la propiedad. Además, su participación varía según la decisión agrícola bajo consideración. De todos modos, nuestro análisis conduce a una conclusión sobresaliente: los datos censales proporcionan una visión distorsionada de la agricultura familiar porque no se toma en cuenta que las decisiones agrí- colas son tomadas frecuentemente por la pareja y conllevan a una subestimación de la participación de las mujeres casadas/ unidas como agricultoras.

Authors: Cordero-Cortés Patricia , Núñez-Espinoza Felipe , Hernández-Romero Oliverio , Arana-Coronado Oscar A.
Published: October 2017

En esta investigación se explican los factores resilientes identificados en micro y pequeñas empresas rurales (MIPyMES), a partir de la construcción de un listado de factores obtenidos de proyectos de la Red Nacional Desarrollo Rural Sustentable (RENDRUS) y confirmados mediante estudio de casos de unidades económicas localizadas en el municipio de Ziracuaretiro en el estado de Michoacán, México. Las MIPyMES son medios de desarrollo rural para México y objetos de estudio por su capacidad de sobrevivencia. Las principales contribuciones de este trabajo son: ayudar a establecer una definición de resiliencia empresarial, identificar los factores resilientes, a partir de los factores de riesgo y protectores, y contribuir con una idea del tipo de situaciones críticas que atraviesan las empresas rurales en México. El método de estudio tiene dos partes. La primera consistió en la revisión de literatura y la segunda en la elaboración de estudios de caso, con mayor análisis en la parte sociocultural y en la estructura organizacional de la empresa rural. Los principales factores resilientes identificados fueron: el logro de una mayor coordinación grupal, un mayor compromiso grupal, honestidad, adquirir más disciplina grupal y productiva, así como establecer alianzas estratégicas, entre otras.

El arroz (Oryza sativa L.) en México ocupa el cuarto lugar en la producción de granos alimenticios, detrás del maíz, frijol y trigo. La producción nacional ha cubierto una parte de la demanda interna, recurriendo a las importaciones y situando al país como un importador neto, ya que durante el periodo de 2010 a 2012, 85 % del consumo de arroz pulido provino del exterior. El objetivo de la investigación, es evaluar la competitividad de la producción de arroz en México ante EE. UU. como principal socio comercial, con el fin de proponer acciones que contribuyan a mejorarla. Se realizó un análisis de la competitividad a nivel macroeconómico utilizando los Índices de Ventaja Competitiva Revelada Aditiva, de Apertura Comercial, y de Autosuficiencia Alimentaria. Además de una comparación de subsidios que reciben los productores de arroz en México y los EE. UU. con información de la Organización para la Cooperación y el Desarrollo Económicos (OECD). Identificando como contribuye en la competitividad del cereal, a EE. UU. como exportador de arroz y México un importador. A nivel microeconómico se compararon costos de producción del ciclo agrícola 2012 de EE.UU., con los estados mexicanos de Michoacán, Morelos y Campeche. La producción de arroz resultó no competitiva en Campeche, pero si en Michoacán y Morelos.
Actitud de cafeticultores sobre el manejo y conservación de suelos del sitio Ramsar, Cascadas de Texolo.

El cultivo del café (Coffea arabica L.) es de gran importancia económica, cultural y ambiental en el Sitio Ramsar Cascadas de Texolo y en su entorno, decretado como Área Natural Protegida. La degradación física, química y biológica del suelo en esta zona se ha incrementado; por lo que es prioritario realizar investigación tendiente a su manejo y conservación. El objetivo de este estudio fue conocer el historial y la actitud de cafeticultores del Sitio Ramsar Cascadas de Texolo hacia la adopción de prácticas de manejo y conservación del suelo. El estudio se realizó en localidades de Xico y Teocelo, Veracruz, mediante una encuesta que empleó un cuestionario aplicado a 40 cafeticultores cuya parcela se ubica dentro del polígono del Sitio Ramsar. Se encontró que las obras y prácticas de conservación de suelo fueron impulsadas al inicio de los años setenta por el desaparecido Instituto Mexicano del Café (INMECAFÉ) algunas de las cuales se siguen manteniendo y practicando. La edad promedio de los encuestados superó los 61 años, de los cuales 60 % son pequeños propietarios, 22 % medianos y 18 % grandes. De los productores 80 % alguna vez establecieron obras o ejecutaron prácticas de conservación. Sin embargo; actualmente sólo 45 % sigue realizando prácticas de conservación de suelo dentro del Sitio, a pesar de haber sido denominado Ramsar. Se encontró una actitud ligeramente positiva (3.3), en escala de Likert, hacia la conservación del agroecosistema cafetalero. Productores con mayor superficie cultivada presentan mejor actitud hacia la conservación de suelo (4.4), lo que podría estar relacionado con que son los que tienen mayor grado de escolaridad. Se concluyó que las actividades tendientes a la conservación de suelo que se practican en el Sitio Ramsar fueron producto de capacitaciones anteriores que aún tienen influencia y que han ido reduciéndose considerablemente a pesar de existir una actitud positiva entre los cafetaleros hacia el manejo y conservación del recurso.
La ruta del tabaco: migración temporal entre Nayarit, México y la Costa Este de Estados Unidos.
Authors: Madera-Pacheco Jesús A. , De Dios Hernández Dagoberto
Published: October 2017

 

Nayarit es el principal estado productor de tabaco en México; sin embargo, dicha actividad ha venido a menos desde principios de los años ochenta, principalmente reflejada en una reducción de la superficie cultivada de tabaco y en el número de productores habilitados. El objetivo general de este trabajo consiste en dar a conocer el impacto que el fenómeno migratorio Santiago Ixcuintla, Nayarit-Costa Este de Estados Unidos ha tenido entre los migrantes y sus familias en términos de agricultura, capital económico, capital intelectual y capital social. Como eje que guía la presente investigación planteamos que el empleo en los campos de tabaco en Estados Unidos es uno de los factores importantes por los cuales no ha tenido eco la política de reconversión productiva para el tabaco en Nayarit que entró en vigor a partir de 2004. La histórica producción tabacalera en Nayarit ha formado una mano de obra especializada que emplean en los tabacales de Estados Unidos; así entonces, ¿cómo dejar la actividad que les permite ser la mano de obra especializada por la cual son contratados, en un lugar donde les pagan como jornaleros, hasta diez veces más de lo que ganan aquí como productores?
