Sixty undergraduate students made category membership decisions for each of 132 candidate exemplar-category name pairs (e.g., chess – Sports) in each of two separate sessions. They were frequently inconsistent from one session to the next, both for nominal categories such as Sports and Fish, and ad hoc categories such as Things You Rescue from a Burning House. A mixture model analysis revealed that several of these inconsistencies could be attributed to criterial vagueness: participants adopting different criteria for membership in the two sessions. This finding indicates that categorization is a probabilistic process, whereby the conditions for applying a category label are not invariant. Individuals have various functional meanings of nominal categories at their disposal and entertain competing goals for ad hoc categories.

The main goal of the study is to analyze the link between Grit and Life Attitude, and its relation with the permanence and academic performance of students from the National Defense University. This paper is mainly focused in the link between the first two constructs. Grit is defined as the passion and constancy to achieving goals, to resisting with effort and interest towards the challenges and difficulties, which is a leader’s attribute (Duckworth, Peterson, Matthews y Kelly, 2007). Life Attitude based on the existential belief that life has a purpose, that persons draw meaning from a variety of sources: recreational and creative activities, personal relationships, achievements (Reker - Woo, 2011). A non-probabilistic sample was formed, for convenience, of 162 students; a sociodemographic questionnaire designed ad hoc; the Scale of Determination (Grit Scale) (Duckworth et al., 2007), which is in the process of validation (Tortul and Daura, in evaluation) and the Life Attitude Test (LAP-R (VE-AA)) in the Spanish adaptation of Barni (2017) were administered. Statistical analysis were made from the collected data, in order to corroborate if there were differences in the variables. The first results showed differences according to career and sociodemographic variables; the undergraduate students obtained higher scores in the positive dimensions of the LAP-R than in other researches made in the same geographical context. The work evidences data of interest in the training of defense professionals, for the decision making in the educational style necessary for an integral formation as a lifelong process.

Desde hace casi un siglo la preocupación de las universidades sobre la satisfacción de los estudiantes con la calidad de la docencia recibida se ha ido incrementando. La revisión de la literatura permite clasificar los atributos de una docencia de calidad en tres grandes tipos de competencias: pedagógicas, genéricas y disciplinares. El objetivo de este trabajo es señalar las variables, que a juicio de los estudiantes, más influyen en la satisfacción del alumnado con la calidad de la docencia. Los participantes fueron 476 estudiantes del grado de Administración y Dirección de Empresas de la Universidad Castilla La Mancha. Se utilizó un cuestionario construido ad hoc para valorar la satisfacción de los estudiantes con la docencia. Se utilizaron pruebas paramétricas (Análisis de Regresión Logística) y no paramétricas (árbol de decisión). Nuestros datos indican que si el profesor explica con claridad, se preocupa por averiguar si los conceptos explicados han sido entendidos y prepara sus clases la valoración sobre la calidad de su docencia será muy satisfactoria. El identificar los atributos de una docencia de calidad permitirá a las universidades elaborar planes de formación inicial y permanente de su profesorado teniendo presente el papel crucial que juegan las competencias genéricas, pedagógicas y disciplinares en la interacción profesor-estudiante. For almost a century now, the concern of universities about student satisfaction with teaching quality has been increasing. A literature review has enabled the attributes of quality teaching to be classified into three main types: pedagogical, generic, and disciplinary. The aim of this paper is to identify the variables that, in the opinion of students, most influence student satisfaction regarding teaching quality. A total of 476 undergraduate students participated from Business Administration and Management of the University of Castilla-La Mancha (Spain). An ad hoc questionnaire was used to assess student satisfaction with teaching. Parametric (Logistic Regression Analysis) and non-parametric (Decision Tree) models were used. Our data indicate that if the professor explains the subject clearly, is concerned to find out whether the explanations have been understood, and carefully prepares the classes; the teaching-quality assessment will be very satisfactory. The identification of the attributes of quality teaching will enable universities to draw up initial and ongoing training plans for their teaching staff, bearing in mind the crucial role played by generic, pedagogical, and disciplinary competences in professor-student interaction.
