Examining the role of export competitive advantages on export performance

This paper investigates the role of export competitive advantage on export performance in food industry. The proposed study designs a questionnaire in Likert scale and distributes it among 280 randomly selected experts in food industry and Cronbach alpha has been calculated as 0.827. The study has applied factor analysis to find important factors influencing export performance. Kaiser-Meyer-Olkin Measure of Sampling Adequacy and Bartlett's Test of Sphericity have been performed to validate the results and they both validated the questionnaire. The results of the survey have determined six effective groups including product development, e-commerce, marketing planning, organizational performance, competitiveness and supply chain management

Western Fires are Burning Higher in the Mountains at Unprecedented Rates: It’s a Clear Sign of Climate Change

The Western U.S. appears headed for another dangerous fire season, and a new study shows that even high mountain areas once considered too wet to burn are at increasing risk as the climate warms. Nearly two-thirds of the U.S. West is in severe to exceptional drought right now, including large parts of the Rocky Mountains, Cascades and Sierra Nevada. The situation is so severe that the Colorado River basin is on the verge of its first official water shortage declaration, and forecasts suggest another hot, dry summer is on the way. Warm and dry conditions like these are a recipe for wildfire disaster

The Role of Urban Agriculture Approach in Food Supply and Export Ability (Case Study of Neishabour in Iran)

The growth of cities and the increase of urban population in recent years has caused many problems for the health of the environment and citizens. On the other hand, given that urbanism is inevitable, we must think of ways to reduce the pressure on nature by cities and improve economic and social indicators in cities. Urban agriculture will play an effective role in establishing a logical relationship between urban needs and improving the economic situation. In this research, the study of the role of urban agriculture from an economic point of view, especially in the field of food supply and export ability has been emphasized. The research method is descriptive-analytical and based on collecting survey data (field). The main research tool is a questionnaire. Its validity was confirmed by elites and its reliability was confirmed by completing 30 questionnaires through Cronbach's alpha at a level greater than 0.70. The study population was 264,375 citizens living in Neishabour. The sample size was determined by Cochran's formula equal to 384 people. The results showed that urban agriculture is significant in food supply and export ability at a level of less than 0.05. The city's agriculture can be effective in improving the export of organic products, fruits and vegetables, exports of ornamental and medicinal plants, branding of products, as well as in supplying fresh vegetables, providing healthy food, improving the quality of nutrition and protein. Urban agriculture has a significant level of less than 0.05 in urban development indicators such as improving the urban environment, improving employment, improving citizens' incomes, creating attractive urban spaces, rainwater consumption, etc. From the people's point of view, it is possible to cultivate crops such as peaches, Damask rose, poultry breeding, etc., according to the available spaces. The study of the role of urban agriculture through structural equations shows that the total effect is 0.81 and in total urban agriculture can explain about 56% of the variance of role-playing and two variables of meeting food needs and export ability

Transmission de l'énergie magnétique et étude des machines électriques et leurs systèmes de freinage dynamique

Dans l’industrie manufacturière et véhicule électrique, dans le but d’éviter les accidents malheureux, la commission de santé et de sécurité au travail (CSST) a exigé récemment l’installation d’un système de freinage d’urgence pour chaque système tournant et manœuvré par les employés. Il s’agit donc d’une opportunité de concevoir un système efficace, intelligent, fonctionnant sans capteurs et permettant en cas de panne électrique et/ou en cas d’urgence d’arrêter la machine tournante à l’intérieur de trois secondes. Ce système peut être actionné par fil ou bien utilisant le principe de communication sans fil, il doit aussi être indépendant du réseau électrique. Ce Mémoire présente la simulation accentuée sur la méthode de calcul Maxwell, un programme informatique visant à réaliser la visualisation et l’acheminement des champs magnétiques dans une machine asynchrone. Maxwell entre autres, propose une nouvelle approche de présentation dynamique des machines basée sur les graphes planaires et trois dimensionnelle. En plus, il intègre également des fonctionnalités de paramétrage des jeux de courant continu, qui permettent de visualiser l’effet des variables indépendantes mécaniques et électriques. En plus, la modélisation électromagnétique se concerne sur une unité de la transmission de l’énergie magnétique et la force mécanique pour l’analyse d’une boîte de disques tournants de l’énergie magnétique dans une plage de puissance active. Enfin, au regard de nos résultats de simulation, chaque variable appliquée au modèle fonctionne comme nous en souhaitait et admet de bonnes performances. En effet, avec ces variables on arrive à résoudre des équations des champs magnétiques et de la vitesse remplacée à la place de la température pour laquelle le programme informatique exige des conditions très complexes

¿Cómo componer una mezcla de mercadeo de medios de comunicación para ganar una campaña electoral? Propuesta de un marco para el marketing político

This article addresses the issue of composing different media to send an integrated message to the voters in electoral campaigns and presents a framework for managing media in political marketing. The authors conducted deep interviews with strategy developers of the past presidential elections as well as two parliamentary elections in Iran to extract the strategy development process for delivering the campaign message to the target audiences. thematic analysis used for analysis of data and interviews coded in three levels of open, axial and selective. The paper suggests a sequence of audience, message and media to launch a successful campaign within a framework that starts with campaign structure and strategy and accomplished with economic effectiveness measuring and success rate.Este artículo presenta un marco para la gestión de medios en campañas electorales. Se realizaron entrevistas a profundidad con desarrolladores de estrategias en las pasadas elecciones presidenciales, así como dos elecciones parlamentarias para extraer el proceso de desarrollo de la estrategia para transmitir el mensaje de la campaña a las audiencias objetivo. El documento sugiere una secuencia de audiencia, mensaje y medios de comunicación para lanzar una campaña exitosa
