El tiempo libre como heurístico del self: una metodología para el análisis de la complejidad del sujeto
No full textLas actividades de ocio y tiempo libre se han considerado importantes para el desarrollo del self – sí mismo – como proceso psicosocial (entre otros, Csikszentmihalyi y Kleiber, 1991; Cuenca, 2008a; Grossman y O’Connell, 2000; Kleiber, 1999; Munné y Codina, 1996, 2002; Wearing y Wearing, 1992). El análisis empírico de este vínculo y los procesos que se generan entre ellos es lo que pretende mostrar la Metodología Cualitativa Secuencial (MCS; Codina, 1999, 2005a y b). Esta estrategia metodológica permite poner de manifiesto la complejidad del tiempo libre, del self y de las relaciones entre ambos (Codina, 2004a y b; Codina y Pestana, 2008; Pestana, 2007; Pestana y Codina, 2005). Como muestra del potencial explicativo de la MCS, en este trabajo se ejemplifica una aproximación empírica al self con base en la dialogicidad derivada de las ideas de M. Bajtín (1961/2003a, 1974/2003b) y en los aspectos complejos —no linealidad, fractalidad, borrosidad— descritos por F. Munné (1997a, 2000) en su modelo del self. Investigar empíricamente propuestas teóricas sobre el self como las de Bajtín y Munné posibilita aprehender las relaciones del desarrollo de la persona con un comportamiento más libre. En un sentido más general, la MCS contribuye a resaltar el carácter vertebrador de la libertad y la mismidad en el análisis del sujeto contemporáneo
Data mining and mall users profile
No full textMarketing scholars have suggested a need for more empirical research on consumer response to malls, in order to have a better understanding of the variables that explain the behavior of the consumers. The segmentation methodology CHAID (Chi-square automatic interaction detection) was used in order to identify the profiles of consumers with regard to their activities at malls, on the basis of socio-demographic variables and behavioral variables (how and with whom they go to the malls). A sample of 790 subjects answered an online questionnaire. The CHAID analysis of the results was used to identify the profiles of consumers with regard to their activities at malls. In the set of variables analyzed the transport used in order to go shopping and the frequency of visits to centers are the main predictors of behavior in malls. The results provide guidelines for the development of effective strategies to attract consumers to malls and retain them there
Is student procrastination related to controlling teacher behaviours?
Get PDF[EN] Even motivated students procrastinate, for procrastination is triggered by a volitional (rather than by a motivational) problem. However, many factors, such as learning context, teacher interpersonal style, and also type of motivation may influence the occurrence of procrastination. The aim of the present study was to assess the relations between first-year university students’ procrastination and controlling teacher behaviour. Four types of controlling teacher behaviour and three distinct measures of procrastination were ecvaluated and their correlations assessed. Findings revealed small but significant associations between (a) conditional use of rewards and decisional procrastination, and between (b) excessive personal control and procrastination linked to avoiding tasks. Results suggest that controlling teacher behaviours might influence students’ psychological experiences in learning negatively. Teachers who do not refrain from constant use of conditional rewards may deffer students’ decision processes regarding their own autonomous academic learning, and excessive personal control may favour students’ perceptions of external regulations, decreasing intrinsic motivation and autonomous self-regulated learning and, thus, making it more likely to engage in alternative activities, procrastinating academic learning.Valenzuela, R.; Codina, N.; Pestana, J.; González-Conde, J.

Critical analysis and digital literacy in learning social psychology
Get PDF[EN] This paper presents a teaching experience in social psychology learning, aimed at students’ acquisition of critical analysis and digital literacy competences at the University of Barcelona. The methodology consisted of asking each student to answer to a socially relevant question, by means of (a) identifying key underlying psychosocial processes and (b) searching for adequate keywords in scientific databases such as PsycNet and Sociological Abstracts, in order to (c) select and critically compare two relevant articles that could answer this question. The acquisition of these competences was assessed with a rubric and related questions in the final exam. Results indicated both the effectiveness of this approach to teach competences in digital literacy and critical analysis through motivating questions, and the translation of these competences in other situations. This approach also showed to be more effective in teaching these ompetences than only giving lectures. This methodology is promising, as it provides an answer to how to give future professionals competences in answering effectively and rigorously to socially relevant problems in the Information Society.González-Conde, J.; Codina, N.; Valenzuela, R.; Pestana, J.

Observation of solution-induced corneal staining with fluorescein, rose bengal and lissamine green
No full textEver since sodium fluorescein (‘fluorescein’ [FL]) was first used to investigate the ocular surface over a century ago, the term ‘staining’ has been taken to mean the presence of ocular surface fluorescence [1]. This term has not been necessarily taken to infer any particular mechanism of causation, and indeed, can be attributed to a variety of possible aetiologies [2].\ud
\ud
In recent times, there has been considerable interest in a form of ocular surface fluorescence seen in association with the use of certain combinations of soft contact lenses and multipurpose solutions. The first clinical account of this phenomenon was reported by Jones et al. [3], which was followed by a more formal investigation by the same author in 2002 [4]. Jones et al described this appearance as a ‘classic solution-based toxicity reaction’. Subsequently, this appearance has come to be known as ‘solution-induced corneal staining’ or more recently by the acronym ‘SICS’ [5].\ud
\ud
The term SICS is potentially problematic in that from a cell biology point of view, there is an inference that ‘staining’ means the entry of a dye into corneal epithelial cells. Morgan and Maldonado-Codina [2] noted there was no foundation of solid scientific literature underpinning our understanding of the true basic causative mechanisms of this phenomenon; since that time, further work has been published in this field [6] and [7] but questions still remain about the precise aetiology of this phenomenon..
El self y sus pluralidades: un análisis desde el paradigma de la complejidad
Get PDFIt is considered shared opinions about
the diverse self-referents definitions and terms. This
diversity is valued in its real scope, and interpreted as a
necessary pluralism to analyze a complex phenomenon
such as the self. In this sense, some self-referential
analysis from linear and complex perspectives are considered,
showing some of their main differences according
to an epistemological standpoint. Following this,
a theoretical complexity-based model of the self is presented;
this model permit to explain the question of
diversity in self research, and to set forth some criteria
to develop an integrated self conception coming from
different theories. Besides, considering self interactive
aspect makes to propose an analysis of complex nuances
in environmental influences that affect self-referents
system; specifically, those related to an interactive
power studied in Microphysics, and the asinthotic
freedom -which contradicts the classical views about
the load of the interaction strength. This analysis is
translated into some complex elements in others'
influence in the self.Acerca de la diversidad de definiciones y
términos autorreferenciales se considera la opinión
compartida sobre la problemática de la misma. Se valora
el alcance real de dicha diversidad y se observa que
ésta puede ser interpretada como pluralidad necesaria
en el análisis de un fenómeno complejo como el self
(sí mismo). Se consideran algunos análisis autorreferenciales
que se practican desde concepciones lineales y
complejas y se muestran algunas de las mayores diferencias
según el enfoque epistemológico. A partir de
aquí se presenta un modelo teórico basado en una concepción
compleja del self y, tomando como referencia
este modelo, se explica la problemática de la diversidad
en la investigación del self y se plantean criterios para
el desarrollo de una concepción integradora de diversas
orientaciones. En esta misma línea, atendiendo a la
dimensión interactiva del self se propone un análisis de
ciertos aspectos complejos de la influencia del medio
sobre el sistema de autorreferencias. En esta propuesta
se consideran algunos tipos de fuerzas interactivas se
dan en la microfísica y un efecto que contradice las
concepciones clásicas sobre el poder de las fuerzas de
interacción: la libertad asintótica. En relación con lo
visto a lo largo del trabajo, se plantea un análisis que
pone de manifiesto ciertos aspectos complejos de la
influencia de los otros sobre el self
