Maria Mercè Mach Piera (Facultat de Psicologia, Ciències de l´Educació i de l´Esport Blanquerna) ha defensat la tesi que porta per títol  La validesa del model triaxial de la confiança organitzativa com a predictor de l'efectivitat, dirigida pel Dr. Simon Dolan i per la Dra. Vicenta Sierra:

This thesis studies the relationship between trust and organisational effectiveness in the         context of interactive professional sports. (In spite of the growing interest in management literature on organisational trust and its influence on effectiveness and results, very few empirical studies have analysed it from the team perspective). The objective of this research is to empirically research how far the perception of players' trust (between team members, their relationships with the principle coach and the club as a whole) can predict future team action. Another factor considered was the possible moderating effect of the coach’s management style (transactional or transformational leadership), along with group cohesion and organisational policies.

This empirical work analyses the results of field work done between March and April 2005 with 700 athletes from 59 professional teams in the Spanish premier sporting leagues for basketball (ACB), handball (ASOBAL), skate hockey (OK-Liga) and indoor football (Liga de Honor). It used a combination of ANOVA and regression analysis to estimate the relationships proposed in the research model. The results obtained provide evidence that one group of variables exercises a mediating effect between the actual and future results of the team. Our results explain 68.6 % of the variance.

Feliciano Sesé Muniátegui (ESADE ADE) ha defensat la tesi que porta per títol Propuesta de un método de validación de esquemas conceptuales y análisis comparativo de la noción de información en los métodos de desarrollo de sistemas de información, dirigida pel Dr. Eduard Bonet i Guinó:

The techniques used by conceptual modelling are an essential component in many development methods for Information Systems (IS). However, such techniques usually pay little or no attention to the problem of validating the conceptual schema. This paper explores a technique that is based upon a conceptual schema to draw up IS specifications that are both formally stated and intelligible to users.

The technique is based on reducing company forms to axioms. For this purpose, a grammar is defined to express a company’s forms as formulae. A procedure then turns the conceptual schema into formulae employing this grammar. The transformed conceptual schema thus represents the calculus axioms. A set of inference rules are then applied to obtain the forms (stated as calculus theorems) to be employed by users. This allows users to validate the conceptual schema through the forms they work with whilst also achieving a formal specification of the system that programmers cannot misinterpret.

Eloí Terezinha Lauxen Peruzzolo (Facultat de Psicologia i Ciències de l'Educació i de l'Esport  Blanquerna) ha defensat la tesi que porta per títol La Senectud Centrovertida. La actitud, los tipos y la función psicológica inferior asociada a la hipertensión en sujetos mayores hipertensos, dirigida pel Dr. Pere Segura i Ferrer i pel Dr. Francesc Xavier Marín Torner:

El objetivo general de esta investigación ha sido demostrar la posible relación existente entre la hipertensión, la actitud consciente, los tipos y las funciones psicológicas en sujetos mayores. Con los resultados se pueden comprobar las siguientes hipótesis:

Personas mayores e hipertensas pertenecen en mayor número a la actitud introvertida y en menor número a la extravertida; En personas mayores introvertidas e hipertensas se observa, de manera estadísticamente significativa, el predominio de un tipo psicológico que sumado a su función inferior correlaciona con la hipertensión. A partir de los resultados se sugieren psicoterapias orientadas para los sueños, dibujos, juegos de arena, modelación en arcilla, pintura e imaginación activa, individual o en grupo.
