Estimated cost of electricity with time horizon for micro grids based on the policy response of demand for real price of energy

The intelligent microgrids are an efficient alternative, which allows to supply the demand decreasing the losses of the electrical system and at the same time; the environment and the consumers are the main beneficiaries. This article develops a heuristic based on an energy management model based on the real price of electricity, which will allow end users to encourage the implementation of a policy of response to demand, in order to optimize their consumption, for which a micro smart grid is analyzed, with conventional and non-conventional renewable generation, In addition, a mechanism of "real energy price" will be implemented as a policy of response to demand, with the aim of optimizing the costs of energy that will be transferred to users depending on the stratum to which it belongs, these costs will have a short-term horizon with hourly intervals, achieving a reduction in the purchase of energy from the syste

Contaminación ambiental generada por la emisión de gases

El ser humano es el único individuo que tiene la capacidad intelectual de administrar los recursos naturales existentes, por tanto es sobre quien recae la responsabilidad de los efectos que se producen dentro del medio ambiente, como lo son las modificaciones climáticas, la contaminación excesiva, el deterioro de la capa de ozono, la infertilidad de los terrenos, entre otros. A partir de la revolución industrial se incrementa la emisión de gases nocivos para el medio ambiente y para la salud del ser humano. El exagerado consumo de artículos generadores de gases contaminantes, como los son los automóviles, aerosoles, refrigeradores, plantas industriales, maquinas a vapor, ha provocado el desequilibrio ambiental, que en la actualidad se hace más evidente en la vida cotidiana.Pregrad

Effects of Management-Development Practices on Hospitality Management Graduates\u27 Job Satisfaction and Intention to Stay

Therefore, one may ask whether the entry-level managers for whom these programs are designed perceive them to be effective. The present study explores management-development practices, procedures, and techniques, and their effects on job satisfaction and organizational commitmen

Corrupción, incentivos y contrabando técnico en Colombia : 1998 – 2013

El contrabando técnico representa un problema para los hacedores de política económica pues tiene efectos perversos en temas fundamentales como la hacienda pública, la competencia de mercado y la informalidad. Sin embargo, a pesar de ser un problema tan importante son pocos los esfuerzos empíricos que se han hecho para estudiar los incentivos que están detrás de esta práctica ilegal, tanto a nivel global como para el caso colombiano. En este trabajo se desarrolla un modelo teórico a partir del cual se estudian los incentivos para la existencia del contrabando, y sus conclusiones se contrastan con una aplicación empírica en la que se utilizan datos de importaciones (reporte de origen y destino) de 24 sectores económicos (583 productos) provenientes de 84 países entre 1998 y 2013. Con estos datos se estima un modelo de panel de datos en el que se encuentra que hay una relación positiva entre la corrupción y el contrabando y también entre los aranceles y el contrabando técnico, indicando que se presenta una mayor subfacturación en productos que tienen aranceles altos y provienen de países más corruptos.Universidad del Rosari

Let\u27s \u27Meetup\u27 at the Theme Park

Many people enjoy theme park and other leisure experiences with their families; however, today a great number of single, geographically mobile individuals desire to partake in such experiences. ‘Meetup’ is the world’s largest social network of local groups and thus allows for both online and off-line (in person) interactions. Using an ethnographic approach, this study examines how individuals can enjoy activities centered on common activities, interests, and opinions (AIO) via immersion in a Meetup group over the course of a year. Notably, members visited with greater frequency, had less tolerance for long lines, and were more likely to attend special events, eat at specialty restaurants, and consume alcohol. Group members also exchanged travel advice and both contributed and detracted from the enjoyment of the theme park experience. Membership in this Meetup group increased the frequency of visits and deeper exploration of the theme park resort, thus improving behavioral loyalty among annual pass holders. Managers can learn from these online communities to foster interactions among their guests and better target this new market

Towards a Model of Electronic Word-of-Mouth and Its Impact on the Hotel Industry

Scholars and practitioners recognize that spreading word-of-mouth can play an important role in the formation of a hotel’s image. However, the relationships among various measures of online customer engagement are relatively unknown. The present study analyzes the relationships and quantifies the impacts of various measures of online engagement including the number of online reviews, overall rating, and relative ranking. The researchers used path analysis on a sample of 178 hotels to study the relationships among relevant variables and build a model to explain the impact of such measures (Figure 2). The results reveal there is a positive direct effect of the number of reviews on a hotel’s TripAdvisor rating. A negative direct effect was found between TripAdvisor rating and a hotel’s comparative ranking. Finally, the researchers discovered that TripAdvisor rating fully mediates the relationship between the number of reviews and a hotel’s comparative ranking. This article concludes with a discussion of both the theoretical and practical implications of such findings

Delighted or Outraged? Uncovering Key Drivers of Exceedingly Positive and Negative Theme Park Guest Experience

Purpose Despite multiple studies of customer delight in various service industries, limited research exists in the hedonically driven theme park context. The purpose of this paper is to explore the key drivers of customer delight and outrage in theme parks by analyzing TripAdvisor’s comments from visitors to the top 20 North American theme parks. Design/methodology/approach Following the analysis of thousands of extremely positive and negative comments using MAXQDA qualitative software, keywords drivers of delight and outrage were identified. The researchers applied both thematic and root cause in order to ascertain the sources leading to both positive and negative consumer feedback. Findings Delighted guests relayed various aspects of their experience including positive affect experience, positive value perceptions, and limited wait times. Root causes that influenced customer delight included: excellent core product, quality food and beverage, servicescape, pricing decisions, and low visitor demand or sensible admissions policies. Outraged guests described various aspects of their experiences such as negative perceptions of value, long waits, poor customer service, and negative emotions. Root causes for customer outrage included low quality or deficient core products, poor quality of food and beverage, poor facility maintenance, aggressive pricing decisions, poor staff selection, training, and working conditions, and high customer demand on any given date or aggressive admissions policies. Originality/value The present research is unique in that it exposes the key themes of customer delight and outrage in the theme park setting, presents a conceptual model, and analyzes its root causes

Stars, Diamonds, and Other Shiny Things: The Use of Expert and Consumer Feedback in the Hotel Industry

Over the past few years, researchers have studied the topic of online consumer feedback. Most of these studies focus on consumer decision making, and managing a hotel\u27s image.Consequently, more research could explore consumer-generated feedback from the viewpoint of hotel operations and service quality improvement. The present research explored the ways in which hotel General Managers use feedback from consumers (namely online), experts, and internal sources to improve service quality. A combination of a quantitative survey and qualitative interviews were utilized. The study targeted General Managers of upscale hotels.Quantitative data was analyzed using multiple and simple regression analysis, correlations, and ANOVA. Results demonstrate that General Managers pay unequal amounts of time and effort to evaluating the various types of feedback. Furthermore, there were also significant differences in the perceived reliability of each source. The present research discovered a strong link between customer satisfaction survey scores and online reviews, as reported by General Managers. The reviews of consumers and experts also displayed significant relationship
