Las empresas que desarrollan estrategias de fidelización tienen mayor probabilidad de ser rentables

Las empresas y marcas actualmente requieren un conocimiento más profundo de sus clientes y garantizar la permanencia de los mismos como consumidores de sus productos y/o servicios a largo plazo. A través de la fidelización de clientes se logra este objetivo en las empresas. Los clientes según su valor son segmentados a fin de establecer estrategias de fidelización, es decir, de lealtad de los usuarios hacía la marca o empresa. Esta segmentación depende del valor que tiene un cliente para la empresa, representado en cuan rentable puede ser. Allí se contemplan variables tan importantes como son, sus características de consumo, sus variables demográficas y psicográficas y la influencia que este sujeto puede tener en el momento de lograr negociaciones de mayor volumen, que impactan directamente en la rentabilidad de la empresaActually brands and companies require a deeper knowledge of the customers and guarantee the permanence of the same as consumers of its products and/or services a long term. Through loyalty of the customers can make this target companies. The customers by value are segmented to strategies to establish loyalty, it means, loyalty of users to brands or companies. This segmentation depends on the value of a customer for the company, represented in how profitable it can be. Here referred to such important variables such as, consumption characteristics, demographic and psycographic variables, and the influence that this person can be at the time of negotiations of higher level, that directly impacted the profitability of the compan

Evaluación de la calidad de los ecosistemas acuáticos a partir del modo de nutrición (IMN) de sus macroinvertebrados. Una adaptación para la educación secundaria

Tanto por las Naciones Unidas como por la Comisión Europea (COM, 1997) se insta al estudio, conservación y mejora de los sistemas acuáticos. En la Península Ibérica y hasta la fecha, los índices utilizados habitualmente para evaluar y determinar la calidad del agua basados en los macroinvertebrados tienen una aplicación restringida a los ríos, ya que, en los demás ecosistemas acuáticos (lagos, lagunas, humedales, etc.) el comportamiento de dichos índices parece que no aporta conclusiones fiables. Con el nuevo índice ecológico presentado en este trabajo, llamado “Índice del Modo de Nutrición” (IMN), se pretende evaluar la calidad de la estructura trófica de las comunidades de macroinvertebrados de todos los sistemas acuáticos continentales y acercar de manera relevante la utilización de los macroinvertebrados acuáticos en la realización de proyectos dirigidos al alumnado de enseñanza secundaria

Antiurolithic activity of Berberis trifoliate extract on induced urolithiasis in rats by zinc disc implantation

Background: In clinical therapy, there is no satisfactory drug available for treatment of urolithiasis, especially for the prevention of their recurrence. The aim of this work was to evaluate in vivo antiurolithic activity of methanolic extract of Berberis trifoliata leaves.Material and methods: Urolithiasis was induced in Wistar rats by zinc disc implantation in urinary bladder. Upon postsurgical recovery, different doses of the methanolic extract of B. trifoliata leaves (50, 100 and 150 mg/kg body weight) were administered orally to zinc disc implanted rats for a period of 20 days. Antiurolithiatic activity was evaluated by measuring the difference between the weight of the implanted zinc discs at the time of implantation and the final weight of the dried calculi taken out from the bladder at the end of the 20 days period of treatment.Results: Extract of B. trifoliata significantly reduced calculi deposition around the implanted zinc disc at all doses (50, 100, and 150 mg/kg).Conclusion: Treatment with methanolic extract of B. trifoliata is useful agent against the kidney stone formation.Keywords: Antiurolithic, Berberis trifoliata, urolithiasis, zinc disc implantation

Los conflictos socioambientales y la construcción de alternativas: experiencias de agricultura periurbana en el sur de la zona metropolitana de Guadalajara, Jalisco, México

El crecimiento desordenado de la zona metropolitana de Guadalajara, Jalisco, México, ha ocasionado una serie de conflictos socioambientales que impactan los recursos naturales y la calidad de vida de los habitantes del entorno periurbano. Ante ello, diversos actores locales se han orientado a construir alternativas a estos conflictos y allí es crucial el papel de la agricultura familiar periurbana, sustentable y multifuncional. En este trabajo se da cuenta de la experiencia del Instituto Tecnológico y de Estudios Superiores de Occidente, que lleva a cabo en la región un proyecto de acompañamiento e investigación participativa, donde se ha formado a los agricultores locales en la transición hacia agriculturas más sustentables, con el que se han demostrado las experiencias de agricultura periurbana, su viabilidad y sus aportaciones a la sustentabilidad regional, y se ha favorecido la articulación de los actores locales con organizaciones regionales y nacionales. Estos procesos se realizan en un tejido social fuerte que es la base para la construcción de alternativas a los conflictos socioambientales. The disordered sprawl of Guadalajara, Jalisco, Mexico has caused a number of environmental conflicts that impact the environment and quality of life of the residents of the suburban surroundings. In response, diverse local actors have focused on building alternatives to these conflicts where it is crucial the role of peri-urban, sustainable and multifunctional family agriculture. The Western Institute of Technology and Higher Education, holds in the region a project of accompaniment and participatory research, which has qualified local farmers in the transition to more sustainable agriculture and demonstrate the feasibility of the experiences of periurban agriculture and their contributions to regional sustainability, finally it has favored the articulation of local regional and national actors. These processes get done inside a strong social network which is the base to the construction of alternatives to socioenvironmental conflicts

Application of directly brewed compost extract improves yield and quality in baby leaf lettuce grown hydroponically

The aim of this work was to study whether the application of a directly brewed compost extract (added in the nutrient solution or by microsprinkler) could be used to improve the yield and quality of baby leaf red lettuce growing in a floating system, and to control the incidence of Pythium irregulare. Its e_ect on the quality of fresh-cut red lettuce was also studied. For this, two experiments were carried out over two growing cycles (winter–spring and autumn). The results showed that the use of compost extract added to the nutrient solution improved baby leaf lettuce growth and quality, reducing the nitrate content and enhancing the content of potentially health-promoting compounds such as phenols and flavonoids and the antioxidant capacity. Microbial quality was maintained during storage and the compost extract had no negative e_ect on the microbial load of the final product. In addition, application of the compost decreased the population of P. irregulare in the water. It is concluded that the application of directly brewed compost extract is of potential use in a sustainable soilless production system for baby leaf red lettuce, since it improves the yield and quality of the product and is able to control the incidence of P. irregulare.This work was supported by projects AGL2017-84085-C3-3-R and AGL2017-84085-C3-1-R from the Ministerio de Economía y Competitividad of Spain

Combined effect of salinity and LED lights on the yield and quality of purslane (Portulaca oleracea L.) microgreens

The present work aims to explore the potential to improve quality of purslane microgreens by combining water salinity and LED lighting during their cultivation. Purslane plants were grown in a growth chamber with light insulated compartments, under different lighting sources on a 16 h d1 photoperiod—fluorescent lamps (FL) and two LED treatments, including a red and blue (RB)) spectrum and a red, blue and far red (RB+IR) LED lights spectrum—while providing all of them a light intensity of 150 _mol m2 s1. Plants were exposed to two salinity treatments, by adding 0 or 80 mM NaCl. Biomass, cation and anions, total phenolics (TPC) and flavonoids content (TFC), total antioxidant capacity (TAC), total chlorophylls (Chl) and carotenoids content (Car) and fatty acids were determined. The results showed that yield was increased by 21% both in RB and RB+FR lights compared to FL and in salinity compared to non-salinity conditions. The nitrate content was reduced by 81% and 91% when microgreens were grown under RB and RB+FR, respectively, as compared to FL light, and by 9.5% under saline conditions as compared with non-salinity conditions. The lowest oxalate contents were obtained with the combinations of RB or RB+FR lighting and salinity. The content of Cl and Na in the leaves were also reduced when microgreens were grown under RB and RB+FR lights under saline conditions. Microgreens grown under RB light reached the highest TPC, while salinity reduced TFC, Chl and Car. Finally, the fatty acid content was not affected by light or salinity, but these factors slightly influenced their composition. It is concluded that the use of RB and RB+FR lights in saline conditions is of potential use in purslane microgreens production, since it improves the yield and quality of the product, reducing the content of anti-nutritional compounds.This project was financed by the Autonomous Community of the Region of Murcia nº 20849/PI/18 through the grant call for projects for the development of scientific and technical research by competitive groups, included in the Regional Programme for the Promotion of Scientific and Technical Research (Action Plan 2018) of the Seneca Foundation-Science and Technology Agency of the Region of Murcia (Spain).
