Mercadotecnia Digital Como Estrategia de Innovación Para el Impulso del Turismo Mexicano en el Contexto de Seguridad Sanitaria

A partir de diciembre de 2019, inicia en China una enfermedad que nadie imaginó que en poco tiempo afectaría al resto del mundo, con el consiguiente colapso social y económico. En este sentido, para el año 2020, como consecuencia de la emergencia sanitaria, el sector turístico se ha convertido en uno de los escenarios más críticos que requiere una capacidad de reacción en el impulso a las políticas públicas que propicien su resurgimiento, el reforzamiento de la infraestructura de comunicaciones y servicios para consumidores y prestadores de servicio, incremento a los presupuestos para reforzar la promoción de los destinos turísticos, entre otros.Sin embargo, hoy por hoy, el componente más importante en la recuperación del sector turístico mexicano es la Innovación, como estrategia gubernamental y empresarial para el desarrollo y aprovechamiento de tecnología inteligente para la creación de soluciones transformadoras para los retos a los que ya se enfrenta el mercado actual. De esta manera, surge un área de oportunidad muy relevante representada por la Mercadotecnia Digital y el uso de las Redes Sociales, que en alianza estratégica con el Turismo, se constituye como un medio para diseñar un modelo integral de gestión para la actividad turística. El presente artículo establece como objetivo identificar las necesidades específicas que presenta el sector turístico y que requieren ser atendidas por la Mercadotecnia Digital como estrategia innovadora mediada por las tecnologías de la información y comunicación, redes sociales y plataformas digitales. Esta investigación de tipo exploratorio, fue diseñada para realizarse de carácter mixto, con enfoque tanto cualitativo como cuantitativo. En su primera etapa muestra los puntos de vista de usuarios frecuentes de las redes sociales en su conocimiento, frecuencia de uso, tipo de canal como rubros que reflejan las necesidades que cubren el criterio de “comunicación efectiva”. Ya en el ámbito turístico, se reflejan los intereses específicos sobre la consulta de páginas web, ubicación de servicios, búsqueda de ofertas y diversidad de productos turísticos comercializados por los diferentes proveedores.   As of December 2019, there was a disease outbreak in China that no one imagined would affect the rest of the world within a short time, resulting to the social and economic collapse of many countries. In this sense, by 2020, as a consequence of the health emergency, the tourism sector has become one of the most critical scenarios that need a reaction capacity in promoting public policies that promote its resurgence, the reinforcement of communications infrastructure and services for consumers and service providers, and increased budgets to reinforce the promotion of tourist destinations among others. Today, the most important component in the recovery of the Mexican tourism sector is innovation. Innovation, therefore, is the strategy used by the government and businesses for the development and use of smart technology to create transformative solutions for the challenges it is already facing. Due to the current market, a very relevant area of opportunity arises by using Digital Marketing and Social Networks. In strategic alliance with tourism, it serves as a means of designing a comprehensive management model for tourism activity. This paper focuses on identifying the specific needs presented by the tourism sector and how to meet this needs using digital marketing as an innovative strategy mediated by information and communication technologies, social networks, and digital platforms. This exploratory research was designed to be carried out on a mixed basis, with both qualitative and quantitative approach. In its first stage, it shows the points of view of frequent users of social networks based on its knowledge, frequency of use, and type of channel as items that reflect the needs that cover the criterion of "effective communication". In the tourism field, specific interests are reflected on the consultation of web pages, location of services, search for offers, and diversity of tourism products marketed by different providers

Thermoelectricity from Macro to Nanoscale: Wave Behaviour and Non-Local Effects

In this chapter, the physical principles to be taken into account in thermoelectricity at the nanometre scale are discussed. We argue that the numerical methods must also be adapted to the emergence of new physical behaviours at that scale, namely, wave propagation of heat, diffusive-ballistic transition, nonlocal effects, among others. It is first shown that thermoelectric phenomena at the nanoscale can be described by introducing thermodynamic inertia and nonlocal effects. The transport equations are obtained from the thermodynamics of irreversible processes. After this, we introduce the Spectral Chebyshev Collocation method as a well-suited numerical method to deal with the new physical behaviours appearing at the nanoscale. We then show the use of these formalisms to analyse specific and interesting aspects of the optimization of pulsed thermoelectricity and coupled thermoelectric modules

Anti-infective properties of medicinal plants from the Baja California peninsula, Mexico for the treatment of Fusarium oxysporum f. sp. basilici in organic sweet basil (Ocimum basilicum)

Certified-organic farming systems in Baja California Peninsula and Northwest Mexico are nationally and globally recognized, especially due to the production of vegetables and aromatic herbs under protected agriculture systems. Based on the background of some species of the flora of Baja California Sur (BCS) to inhibit a diversity of microorganisms, the effect of 22 medicinal plants of the region was explored to know the in vitro activity against the fungus Fusarium oxysporum f. sp. basilici isolated from basil (Ocimum basilicum L.). The plants processed as crude ethanolic and aqueous extracts were analyzed in duplicate (three replicates) evaluating the inhibition of mycelial growth and spore germination. In mycelial inhibition test, all plants extracts (1000 mg L-1) showed an effectiveness of 11 to 40% to inhibit F. oxysporum. The most effective plant extracts according to 50% effective inhibition dose (ED50), were Larrea tridentata, Hymenoclea monogyra and Lippia palmeri with an ED50 of 220, 303 and 3000 mg L-1, respectively. Tukey’s PostHoc tests indicated that H. monogyra and L. tridentata are ten times (ED50 <300 mg L-1) more effective than L. palmeri (ED50 3000 mg L-1). In addition, the dose-response trend analyzes according to the logarithmic-logistic model (drc packages), showed the maximum slope values ​​between 100 and 1000 mg L-1. In the spore germination inhibition tests, most ethanolic extracts (5000 mg L-1) showed an effectiveness between 21 and 80%. The results of this study demonstrated that the inhibitory potential of these plants used in BCS traditional medicine are a viable alternative for the control of F. oxysporum f. sp. basilici in organic basil production systems. Highlights 22 medicinal native plants from the Baja California peninsula can effectively inhibit (in vitro) oxysporum f. sp. basilica. The most effective species were Larrea tridentata, Hymenoclea monogyra and Lippia palmeri with a mycelial growth inhibition (ED50) of 220, 300 and 3000 mg L-1, respectively. In vitro effectiveness of Fusarium-growth inhibition of medicinal plants of BCS were in ED50 ranges from 220 to 3000 mg L-1. Creosote bush (L. tridentata) extract at a dose of 5000 mg L-1 can inhibit the fungal sporulation by up 80%. The ethanol-aqueous extract of the medicinal plants of BCS have the potential to be used for long-term control of the fusariosis disease in basil.Certified-organic farming systems in Baja California Peninsula and Northwest Mexico are nationally and globally recognized, especially due to the production of vegetables and aromatic herbs under protected agriculture systems.

Optimization of the physic, optical and mechanical properties of a composite edible films of gelatin, whey protein and chitosan

Artículo indizadoThe aim of this work was to evaluate the effect of the concentration of gelatin (G) (3–6 g), whey protein (W) (2.5–7.5 g) and chitosan (C) (0.5–2.5 g) on the physical, optical and mechanical properties of composite edible films (CEFs) using the response surface methodology (RSM), as well as optimizing the formulation for the packaging of foods. The results of the study were evaluated via first‐ and second‐order multiple regression analysis to obtain the determination coefficient val‐ ues with a good fit (R ˃ 0.90) for each of the response variables, except for the values of solubility and b*. The individual linear effect of the independent variables (the concentrations of gelatin, whey protein and chitosan) significantly affected (p ≤ 0.05) the water vapor permeability (WVP), strength and solubility of the edible films. The WVP of the edible films varied from 0.90 to 1.62 × 10−11 g.m/Pa.s.m2, the resistance to traction varied from 0.47 MPa to 3.03 MPa and the solubility varied from 51.06% to 87%. The optimized values indicated that the CEF prepared with a quantity of 4 g, 5 g and 3 g of gelatin, whey protein and chitosan, respectively, provided the CEF with a smooth, continuous and transparent surface, with L values that resulted in a light‐yellow hue, a lower WVP, a maximum strength (resistance to traction) and a lower solubility. The results revealed that the optimized formulation of the CEF of G–W–C allowed a good validation of the prediction model and could be applied, in an effective manner, to the food packaging industry, which could help in miti‐ gating the environmental issues associated with synthetic packaging materials.Consejo Nacional de Ciencia y Tecnologí

Diffie-Hellman Protocol Based on Elgamal and AES Cryptosystems

Abstract : -This paper presents a communication scheme design for securing messages through local area networks (LAN). This scheme implements a hybrid cryptosystem which is formed by AES-256 in its symmetric part and ElGamal for encryption of keys where the prime has 400 digits and 200 digits for the alpha primitive. It also applies the Diffie-Hellman protocol for key secure distribution. This implementation is targeted at senior management members or groups of any corporate trust where the number of users is small. Key distribution requires a number equal to the number of rounds for at least one user

The European Eel NCCβ Gene Encodes a Thiazide-Resistant Na-Cl Cotransporter

The thiazide-sensitive Na-Cl cotransporter (NCC) is the major pathway for salt reabsorption in the mammalian distal convoluted tubule. NCC plays a key role in the regulation of blood pressure. Its inhibition with thiazides constitutes the primary baseline therapy for arterial hypertension. However, the thiazide-binding site in NCC is unknown. Mammals have only one gene encoding for NCC. The eel, however, contains a duplicate gene. NCCα is an ortholog of mammalian NCC and is expressed in the kidney. NCCβ is present in the apical membrane of the rectum. Here we cloned and functionally characterized NCCβ from the European eel. The cRNA encodes a 1043-amino acid membrane protein that, when expressed in Xenopus oocytes, functions as an Na-Cl cotransporter with two major characteristics, making it different from other known NCCs. First, eel NCCβ is resistant to thiazides. Single-point mutagenesis supports that the absence of thiazide inhibition is, at least in part, due to the substitution of a conserved serine for a cysteine at position 379. Second, NCCβ is not activated by low-chloride hypotonic stress, although the unique Ste20-related proline alanine-rich kinase (SPAK) binding site in the amino-terminal domain is conserved. Thus, NCCβ exhibits significant functional differences from NCCs that could be helpful in defining several aspects of the structure-function relationship of this important cotransporter
