This paper aims to present a proposal to improve this methodology for the analysis of heterogeneous capacities based on the profit margin per product. Which was structured in three moments: development of the proposal, deployment in a business context, and validation of the results through the application of a linear programming method. This proposal considers the five initial steps of the existing tools as a starting point, taking as a reference the normal time available for each homogeneous group and introducing modifications in the steps. The application of the methodology in the conditions of SMEs demonstrated its ability to generate results superior to those of traditional methods and similar to those obtained by specific linear programming techniques.

This paper aims to establish a model of structural equations that summarizes the degree of incidence of variables related to job satisfaction in organizations. It starts from the identification of the variables to analyze according to the literature on the subject and those that were corroborated through the consultation of experts, later proceed to the construction of instruments for their measurement and application of these to 4,235 employees in 150 entities from different productive sectors. With the results obtained in the surveys, a confirmatory factor analysis was developed, which verified the incidence of the variables evaluated in the work satisfaction and later proceeded to the construction of the model. The model obtained shows the relationship between the different variables that affect job satisfaction and confirming its multifactorial character as a construct. The data that facilitated the generation of the model allow to establish a logic of management of the job satisfaction from managing in an integrated way the latent variables that condition them, ensuring their correct management, such as: the design of work content, working conditions, interpersonal relationships with peers in general and with managers in particular, policies and methods of stimulation and the group work.

The purpose of this research is to analyze the perception of the environment by SME owners and managers. The research methodology used in this study involved collecting information from 384 SME owners-managers from different sectors of the economy in Santo Domingo de los Tsáchilas, Ecuador. Proportional stratified sampling was used with 95% confidence and an error of 5%. The data was collected through a self-administered cross-sectional survey questionnaire that aimed to get SME owner-managers to describe how they perceive their environment making a combination of the value of each variable. The study applied categorical principal component analysis (CATPCA) to identify the component structure of social capital by considering the ordinal and nominal nature of the data. The methodology used allowed us to understand the perception of the environment by different SME owner-managers from different sectors of the economy. It also revealed the strategic approach they considered most appropriate to the market situation in which they operate. The practical implications of this research suggest that SME owner-managers can benefit from understanding the perception of the environment by adopting flexible and adaptable solutions to changing environmental conditions, using environmental profiles to uncover opportunities, and anticipating changes to gain valuable insights.

This research focuses on characterizing the orientation of the research that shows the contributions in the field of administrative sciences in Latin America. To do this, publications on Administrative Sciences by researchers in the region reported in Scopus were analyzed. After an initial review of all these publications, the sample was reduced to 87%, identifying the functions or areas of knowledge towards which they were oriented, their evolution over time, the sectors and countries where they were published, the collaboration networks between countries based on the development of the research and the main journals where they have been published. The results show that the administrative sciences are present in the epistemological development of Latin America, its conception and evolution correspond to the theoretical and methodological principles that established it as a science; They also reflect the existence of a vast network of collaboration in research in this field between countries in the region and beyond. At the same time, they show the need to strengthen the ties of collaboration between the most prolific researchers to strengthen the existence of an autochthonous school that responds to the particularities of the socioeconomic environment where they develop.
