Escuelas de negocios latinoamericanas Un análisis empírico

Drawing on recent available data of a sample of Latin American business schools, this paper aims at identifying the organizational determinants of the students’ success in their post-MBA professional work. These relationships are tested through multiple regressions using panel data with random effects. The main finding is that the level of scholarly knowledge production, operationalized as number of articles published in journals indexed in the Social Science Citation Index, is in a positive and statistically significant way associated with the alumni’s success. The quality of the faculty has also a positive and significant effect upon the dependent variable, although this result is not robust as per different model specifications.     

Análisis del servicio de Urgencias aplicando teoría de líneas de espera

Those responsible for making decisions in hospitals are increasingly aware of the need to efficiently manage hospital systems. An option for analysis is done by queuing models. In this paper is analyzed the service area ER, in a public hospital applying the concepts and relationships of waiting lines. From the model results, it is concluded that in the emergency department does not have the required minimum number of doctors to allow a steady flow of patients. With the model, the minimum required number of doctors is calculated to meet current and future demand for service with the same service time and the same discipline of service. Analytical models, allowing direct understand the relationships between service demand, number of doctors and patient care priority viewed as a queuing system. The work is useful for administrators and managers of hospital systems.     

La medición del desempeño social empresarial a través de las redes sociales

Corporate social performance (CSP) has been studied extensively by management scholars, yet most approaches to its measurement continue to be ambiguous, controversial and difficult to research. In this paper, we propose measuring CSP via the construct of stakeholder satisfaction through social media. Using organizational justice theory, we argue that the satisfaction of stakeholder expectations can be understood partly through the perception of unjust corporate behavior, which is then expressed by stakeholders through social media. The explosion of social networking and microblogging has made it possible for people to express opinions with respect to the economic, social, and environmental events for all sorts of firms. We test these ideas using event study methods with a sample of 5,440 observations from ten firms. We find preliminary evidence of the sensitivity of social media to these events.     

Análisis de costos y estrategias productivas en la lechería de pequeña escala en el periodo 2000–2012

An accounting analysis was performed on the evolution and performance of productive, economic and marketing strategies implemented by small-scale dairy farmers in the peri-urban area of Texcoco, Mexico. Economic and production records for 1 023 lactation were obtained in two periods, 2000 and 2012. The general cost methodology was used to establish the accounting structures of these production systems, and the re-adjustment of values financial methodology through calculating deflated values based on data from the Mexican National Index of Consumer Prices. Evidence is presented that farmers in Stratum I defined as strategies not hiring temporary or permanent labour, as well as independence in the purchase of inputs (this Stratum produces 90% of its inputs). Stratum II reduced 3 of the main 4 items of the total production cost (feeding, medicines and breeding) and increased the mean profit per litre of milk ($ 2.00 MXN) through selling strategies. Stratum III defined as their strategies increased productivity (59%), a reduction in the cost (29%) of the main input (feed) and taking advantage of their productive scale to obtain a higher receipt of revenues for the farm.     

Un análisis de la gestión por competencias en la empresa española De la teoría a la práctica

This paper is about the competency management, a technique for human resources management aimed at improving the performance of employees and organization performance. Specifically, there are concerns about the high degree of implementation of this technique and its relationship with management performance in specific industries with various economic outcomes.     

Evaluación del efecto de la psicología del inversionista en un mercado bursátil artificial mediante su grado de eficiencia

The main objective in this paper is developing a cellular automaton model where interact more than one kind of broker, where the use and exchange of information between the investors explain the complexity through the Hurst coefficient estimation, this, represents an efficient or random market when the value is equal to 0.5. Due to the variants proposed in this research it can be determined that should exist a rational component in the simulator in order to generate an efficient behavior.     

Evolución de la capacidad tecnológica en México. Aplicación del análisis estadístico multivariante de cluster

This paper conducts an analysis on the existence of state clusters related with technological capabilities in Mexico. An empirical study was conducted using the technique of multivariate statistical cluster analysis, based on the set of indicators proposed by Cepal (2007), collecting data from various public sources country for 2006 and 2012 in order to study the time evolution of such clusters, trying to see what states have been moving to a cluster located in positions more which have advanced and retreated over the period. The results show the existence of 7 groups of states characterized by different technological capabilities, plus states are identified in decline and progress, both in terms of absorptive capacity and innovation, and in relation to the technological infrastructure capabilities.     

Análisis del comportamiento estadístico y aproximación fractal en la recaudación del impuesto sobre nóminas y asimilados en el estado de Quintana Roo

This paper analyzes the tax collection from payroll tax on staff and non-staff in the state of Quintana Roo from 2000 to 2010. Its main contribution is to identify the statistical revenue behavior using a fractal approach, establishing iterative patterns at both state and municipal level, for the entire analyzed series of 132 months as well as shorter time periods. It serves as a trigger for application in other locations and charges in order to explore some features of taxation. Two statistical criteria were used to determine normal or abnormal series of municipal tax collection during the study period, namely, the Empirical Rule criteria and parameters using Chebyshev’s theorem. As a contrast, the Jarque-Bera test was applied on residuals, concluding that the fiscal revenue from the state of Quintana Roo (municipal data) does not follow a normal distribution, which is why the fractal approach has been used. The results with data for tax collection by municipalities throughout Quintana Roo show the presence of a fractal behavior (repetitive and cyclic) in revenue, which can be interpreted as the presence of a consolidated tax base, thus justifying the conclusion that there is strength (the observed level of collection) in local public finances. The same conclusion is obtained, with different temporal cuts, when analyzing and detecting the presence of specific fractal revenue behavior observed in municipalities of Benito Juarez (Cozumel) and Othon P. Blanco from 2000 to 2010.     

Aprendizaje,innovación y gestión tecnológica en la pequeña empresa: Un estudio de las industrias metalmecánica y de tecnologías de información en Sonora

In the industrial development in Northwestern Mexico stands out the limited capacity of local firms to integrate into the global value chains and there is an emergent participation of the metalworking sector and information technology as suppliers of goods and services for large exporters. Recent local researches analyze the accumulation of technological capabilities, but they have not researched the relationship with technology management strategies. This paper presents the results of an empirical study of micro, small and medium enterprises in such areas, which allows the guessing of a direct correlation between the level of accumulated skills and the level of technology management.
