RESUMENEste trabajo tiene como propósito desarrollar un modelo sistémico que explique y permita analizar la conducta ambiental en alumnos de establecimientos educacionales certificados, Región Coquimbo-Chile. Se crea una relación entre cada variable que estructura el modelo conductual exploratorio propuesto, con método de Mínimos Cuadrados Parciales (PLS). Para el análisis conductual, se realiza una encuesta con muestra significativa estadísticamente (7% error y 95% confiabilidad) en establecimientos educacionales certificados ambientalmente, de las ciudades de Coquimbo y La Serena. El modelo estructural tiene una correcta calidad de predicción, el Test de Stone-Geisser (Q2>0), complementariamente la varianza explicada de cada una de las relaciones es aceptable. En consecuencia, se concluye que las actitudes y los amigos de los mismos estudiantes influyen significativa y directamente en su conducta ambiental. Mientras que las estrategias y valores corporativos de los establecimientos educacionales y la familia no tienen una influencia significativa.Palabras clave: estrategias, actitudes, valores, ecuaciones estructurales. ABSTRACT The purpose of this paper is to develop a systematic model to explain and analyze the environmental behavior of students from certified educational instituitons in Región de Coquimbo, Chile. A relationship among variables has been established to structure the exploratory behavioral model presented through a Partial Least Squares (PLS) method. For behavioral analysis, a survey was implemented showing a significant statistical sample (7% error and 95% reliability) of environmentally certified educational institutions. The structural model presents an appropriate prediction quality, Stone-Geisser test Q2>0; additionaly, the variance explained in each relation is adequate. Consequently, it is concluded that attitude and friendship among students themselves affect the environmental behavior significantly and directly. While corporate startegies and values from insitutions and the family do not seem tho affect crucially.
ResumenEl objetivo de la investigación es realizar un análisis de la fidelización del estudiante de ingeniería en relación con su centro de educación superior. Se toma como población objetivo los estudiantes de la carrera Ingeniería Civil Industrial de la Universidad de La Serena, en Chile y se propone un modelo relacional con seis hipótesis de trabajo. Se aplicaron encuestas con tamaño de muestra de 177 estudiantes que representan el 54% de la población, considerando escala politómicas tipo Likert. Para el contraste del modelo propuesto se emplearon los métodos de ecuaciones estructurales. Finalmente, se determinó la confirmación del carácter multidimensional de la fidelidad del estudiante con su centro de educación superior. Basado en ello, se concluye que la fidelidad del estudiante es afectada de forma significativa por la calidad del proceso enseñanza-aprendizaje, que la satisfacción del estudiante influye de manera positiva y significativa, y que la red de apoyo externo es una variable significativa que impacta directa e indirectamente la fidelidad del estudiante. Palabras clave: estudiante, enseñanza-aprendizaje, satisfacción, fidelización, red de apoyo Analysis of Engineering Student Loyalty to his/her Center of Higher Education: Education Management Challenges AbstractThe objective of the research is to analyze the loyalty of engineering students in relation to its center of higher education. Students of the career of Industrial Civil Engineering at the University of La Serena in Chile were considered in the study and a model including six relational hypotheses is proposed. Surveys were applied to 177 students, representing 54% of the population, considering Likert scale polytomous. To compared the results of the proposed model structural equation methods were used. Finally, confirmation of the multidimensional nature of student loyalty with its center of higher education was determined. Based on this, it is concluded that loyalty student is significantly affected by the quality of the teaching-learning process, student satisfaction has a positive and meaningful influence, and that the network of external support is a significant variable that impacts directly and indirectly students 'loyalty.
Instrumental and sensory textural characteristics of frozen blue squat lobster (Cervimunida johni) tails stored at −22C for 0, 15 and 60 days were evaluated. The influence of fishing area (north or south) was also studied. Instrumental texture was evaluated by shear and compression testing using a Warner–Bratzler blade for firmness and a flat plunger with two‐cycle compression for texture profile analysis (TPA) testing. A trained panel was utilized to evaluate textural attributes using the score method. Results showed that fishing area and frozen storage did not affect the textural quality of blue squat lobster tails. However, a strong correlation (r > 0.9) between sensory and instrumental texture parameters was observed. Instrumental chewiness (r = 0.91), cohesiveness (r = 0.96) and sensory hardness (r > 0.84) obtained the strongest correlations. In this way, the use of instrumental analysis may be useful as an alternative to sensory analyses to evaluate the textural characteristics of blue squat lobster tails.
This research analyzes the influence of management control on the public value that is generated in the services dependent on the Ministry of Economy, Development and Tourism of Chile. Surveys with a sample size of 375 officials were applied, using a Likert-type polytomous scale. The results are analyzed by the structural equations method based on partial least squares. The creation of public value is explained in 32.5% by the direct relationship with the achievement of challenging results, which, at the same time, depends significantly on the development of competencies, management focused on the management control, allocation of rewards and a culture of continuous improvement. Thus, the systemic management of these variables will promote the creation of public value, where management control will allow public decision makers to know and proactively learn, according to what is happening at all times, in the processes considered critical for the organization.
ResumenSe presenta un modelo para determinar la conducta intraemprendedora social en estudiantes de Instituciones de Educación Superior, tomando como caso de estudio las carreras de Ingeniería de la Universidad de La Serena, en Chile. Se propone un modelo relacional con ocho hipótesis de trabajo. Se aplicaron encuestas a un grupo de 401 estudiantes, considerando escala politómicas tipo Likert. Para el contraste del modelo propuesto se emplearon los métodos de ecuaciones estructurales, basado en los mínimos cuadrados parciales. Se determinó que la innovación social, la fidelidad del estudiante y la disposición al riesgo explican en un 46,5% a la conducta intraemprendedora social. La identificación del estudiante con su carrera y con su universidad influye de forma directa y significativa en la fidelidad del estudiante. Se concluye que la gestión sistémica de la universidad se debe enfocar en promover la innovación social, fortaleciendo la disposición al riesgo de los estudiantes y mejorar los procesos de enseñanza aprendizaje e imagen institucional. Palabras clave: intraemprendimiento social; innovación social; institución de educación superior; modelo de ecuaciones estructurales; fidelidad Determinant Factors for Social Intrapreneurism: The Case of the Engineering Students of the University of La Serena, ChileAbstract A model to determine social intrapreneurism behavior in students of institutions of higher education is presented, taking as a study case the engineering careers of the University of La Serena, in Chile. A relational model with eight working hypotheses is proposed. A sample of 401 students was studied and a survey was applied, considering a Likert-type politomic scale. For comparing the results of the proposed model the method of structural equations, based on partial least squares was also used. It was determined that social innovation, student loyalty and willingness to risk account for 46.5% of social intra-entrepreneurial behavior, the identification of students with their career and their university influences directly and meaningfully student's fidelity. It is concluded that the systemic management of the university should focus on promoting social innovation, strengthening students' risk disposition and improving the processes of teaching learning and institutional image.
