Non-thermal transitions in a model inspired by moral decisions

This work introduces a model in which agents of a network act upon one another according to three different kinds of moral decisions. These decisions are based on an increasing level of sophistication in the empathy capacity of the agent, a hierarchy which we name Piaget's ladder. The decision strategy of the agents is non-rational, in the sense they are arbitrarily fixed, and the model presents quenched disorder given by the distribution of its defining parameters. An analytical solution for this model is obtained in the large system limit as well as a leading order correction for finite-size systems which shows that typical realisations of the model develop a phase structure with both continuous and discontinuous non-thermal transitions

Personality and music major

Early research investigating the personality of college-aged student and professional musicians examined traits of music performers, composers, and music teachers. Subsequent research studies followed with examinations of personality in university music programs, several of which employed the Myers-Briggs Personality Inventory (MBTI). The prevalence of MBTI types has not been examined amongst the diversity of music programs currently offered in many universities. The purpose of this study was to examine the prevalence of MBTI psychological type of university music students (N = 217) across six different music majors (i.e., Music Business, Music Composition, Music Education, Music Engineering, Music Performance, and Music Therapy). The MBTI mental function of Intuitive–Feeling was found to be highly over-represented in the total music sample as compared to national norms, while several other personality preferences significantly dominated or were sparse in the music majors. The findings extend the personality and music research literature and have practical implications for music educators, academic counsellors, college-aged music students, and students who are considering music as a study and career
