General canonical models for graded normal logics (graded modalities IV)

We prove the canonical models introduced in [D] do not exist for some graded normal logics with symmetric models, namelyKB°, KBD°, KBT°, so that we define a new kind of canonical models, the general ones, and show they exist and work well in every case.     

The Personalities of Presidents as Independent Variables

The debate about the relative importance of the personality traits of presidents has a long history. Until the mid-1970s, scholars of the presidency extensively focused on the uniqueness of the individuals that held office. However, the difficulty in capturing presidential personalities and measuring their impact on executive politics led to a significant quantitative shift that focused more on the institutions within which presidents operate. This change produced a long-lasting divide between researchers interested in the “institutional” presidency and those focused on the “personal” presidency. I propose to integrate both approaches by incorporating insights from differential psychology to treat the personality traits of presidents as independent variables. In support of the argument, I use data from an expert survey that captured psychometric traits of presidents who governed the Western Hemisphere in 1945–2012 to reassess an influential study about Latin American presidents. The results show that adding openness to experience leads to a deeper understanding of presidential approval. I conclude by arguing that measuring the personality traits of all sorts of leaders is necessary to modernize the study of elites.     

Psychological and Social Factors that Promote Positive Adaptation to Stress and Adversity in the Adult Life Cycle

The phenomenon of resilience reflects positive adaptation despite contexts of risk, significant adversity, or trauma (Masten and Powell 2003; Luthar 2006). The purpose of this investigation was to propose a mediation model to explain the relation between stress and some psychological and social resources that enhance positive adaptation throughout the entire adult life cycle, and to explore the moderator role of age and country of origin. The indicator of positive adaptation was life satisfaction (LS). The sample comprised 171 Mexicans and 154 Spaniards (N?=?325), aged between 18 and 87?years. Mediation was tested by means of various hierarchical regression analyses, which revealed that the positive adaptation process is enhanced by a group of psychological and social resources that mediate the effects of stress on LS. Self-esteem, optimism, internal control, coping aimed at acceptance, and coping aimed at seeking emotional support, as well as social contacts can mediate the negative effects of stress. Finally, it was found that age moderates the internal control but none of the remaining variables whereas the country does not moderate the relation of the variables.     

Coping with Stress, Coping with Violence: Links to Mental Health Outcomes Among At-risk Youth

Coping reactions to stressful events are important links between difficult experiences and the emergence of psychopathology. In this study we compared youths?? negative coping with stress in general to their negative coping with violence in particular, and utilized a person-centered analytic approach to examine how patterns of coping relate to various mental health outcomes. We utilized survey interview measures to collect data from a sample of 131 youth (ages 11?C14, 100?% ethnic minority) residing in an economically distressed metropolitan area of the northeast. We observed significant relations between youths?? tendencies to cope with stress and violence via externalized-internalized strategies (e.g., yelling to let off steam, crying) and their mental health symptoms. However, we generally did not observe relations between engagement in distancing coping strategies (e.g., making believe nothing happened) and any problematic outcomes. Negative coping does not appear be a monolithic construct uniformly associated with negative outcomes for youth. Distancing coping might represent an especially useful short-term coping response for youth living in socioeconomically distressed conditions from the standpoint of inhibiting symptom development.     

Semantic and phonemic verbal fluency in Parkinson's disease: Influence of clinical and demographic variables

Changes of cognitive function in PD have been extensively documented and defined as a 'frontal' type executive dysfunction. One of the main components of this executive dysfunction is the impairment of verbal fluency. The aim of the present study was to assess semantic and phonemic fluency in a large sample of PD patients and to investigate the effect of clinical and sociodemographic variables on verbal fluency in this patient group. Three hundred patients with idiopathic Parkinson's disease who were consecutive referrals to our clinic and 50 age and education matched healthy controls completed the phonemic and semantic verbal fluency tasks. Both phonemic and semantic verbal fluency were significantly impaired in PD patients relative to matched controls. Stage of illness, presence of depression, education and age influenced verbal fluency measures. Regression analyses established that global measures of cognitive ability (MMSE) and executive function (FAB) and side of onset of motor symptoms predicted 36-37% of variance of phonemic or semantic verbal fluency measures. Thus, future studies aimed at assessing cognitive functioning in PD patients treated by deep brain stimulation (DBS) should adequately take into account several factors (stage of illness, depression, executive functioning) which may potentially influence performance on verbal fluency tasks.     

De las tormentosas relaciones entre forma y contenido en el pensamiento: crónica de un romance anunciado

Resumen

El presente artículo estudia las complejas y cambiantes relaciones entre forma y contenido en la psicología del pensamiento. Tradicionalmente se han distinguido dos estadios en el razonamiento y la solución de problemas: una fase de representación, centrada básicamente en el contenido del problema, y una segunda fase de proceso o razonamiento propiamente dicho, en la que primarían los aspectos lógico-formales. El artículo analiza la evolución desde los estudios sintácticos del pensamiento—centrados en las reglas formales que lo rigen—a los estudios semánticos, preocupados sobre todo por el contenido de las representaciones, para acabar proponiendo una integración de ambos aspectos dentro de una visión pragmática del pensamiento.     

SCIENCE AND RELIGION IN LATIN AMERICA: DEVELOPMENTS AND PROSPECTS

The state of the debate surrounding issues on science and religion in Latin America is mostly unknown, both to regional and extra‐regional scholars. This article presents and reviews in some detail the developments since 2000, when the first symposium on science and religion was held in Mexico, up to the present. I briefly introduce some features of Latin American academia and higher education institutions, as well as some trends in the public reception of these debates and atheist engagement with it in Mexico and Argentina. The primary conclusion of this article is that, even though the discussion is new to Latin American academic circles, it is gaining traction and will certainly grow in the coming years.
