Purpose The purpose of this paper is to get a consumer’s cross-cultural insight on the potential of using social networking sites as short food supply chains. Design/methodology/approach A qualitative approach, using free listing tasks and sentence completion techniques, was adopted in this research. The research group decided to apply the study in three countries with different cultural backgrounds, namely, Mexico, Spain and Egypt. The final sample consisted of 424 respondents in total, including 209 Spanish, 111 Mexicans and 104 Egyptians, all of them actual users of social networks. Findings The most significant result that emerges from this study is that a high percentage of consumers within the three countries might be interested in these new short food chains. Also, the study offers food companies the most relevant motivations and barriers of consumers for their engagement to this initiative. Also, the study provides categories of foods that consumers would purchase via these chains in each country. Originality/value The multicultural perspective of this study might open new opportunities for food businesses around the world, especially for SMEs, to develop new short food supply chains enabling them to increase sale levels and, therefore, increase profitability and reduce costs.
Bayle y Voltaire hacen una apuesta firme por la tolerancia en circunstancias vitales distintas. Uno, al refutar la interpretación de las palabras de Lucas por parte de san Agustín, que con-ducen a la justificación de la intolerancia para destruir la herejía. El otro, divulgando la conde-na de Calas al patíbulo por el fanatismo papista. Para Bayle hay que actuar en conciencia y libremente, aun en el caso de la conciencia errónea, que tiene, también, sus derechos, y no ir nunca contra la razón. Para Voltaire fanatismo y dogmatismo trastornan y violentan las socie-dades, convirtiéndolas en un infierno. Sólo la tolerancia es el bien social para la pluralidad de creencias. El propósito de este escrito es contrastar la concepción de la tolerancia de ambos autores, que en contextos distintos coinciden en lo básico.
Liquid-in-air generation of monodisperse, microscale droplets is an alternative to conventional liquid-in-liquid methods. Previous work has validated the use of a highly inertial gaseous continuous phase in the production of monodisperse droplets in the dripping regime using planar, flow-focusing, PDMS microchannels. The jetting flow regime, characteristic of small droplet size and high generation rates, is studied here in novel microfluidic geometries. The region associated with the jetting regime is characterized using the liquid Weber number (Wel) and the gas Reynolds number (Reg). We explore the effects of microchannel confinement on the development and subsequent breakup of the liquid jet as well as the physical interactions between the jet and continuous gaseous flow. Droplet breakup in the jetting regime is also studied numerically and the influence of different geometrical parameters is investigated. Numerical simulations of the jetting regime include axisymmetric cases where the jet diameter and length are studied. This work represents a vital investigation into the physics of droplet breakup in the jetting regime subject to a confined gaseous co-flow. By understanding the effects that different flow and geometry conditions have on the generation of droplets, the use of this system can be optimized for specific high-demand applications in the aerospace, material, and biological industries.
