Life satisfaction and perception of happiness among university students

The aim of this essay has been the evaluation of three orientations towards happiness: pleasure, meaning and engagement, as well as their relation to life satisfaction and the perception of happiness in a sample of 320 university students. The results show that the most used kind of orientation towards happiness is pleasure, followed by meaning, and finally engagement. It has also been found that pleasure is the orientation most closely associated to happiness while engagement seems to be more related to life satisfaction. These findings aim to the distinction between the concepts of happiness and life satisfaction and lead the attention to the actions which can improve the levels of happiness.     

Barriers perceived by teachers at work, coping strategies, self-efficacy and burnout

This study examines the relationships among stressors, coping strategies, self-efficacy and burnout in a sample of 724 Spanish primary and secondary teachers. We understood stressors as barriers perceived by teachers that interfere with their work meeting learning objectives and which cause them stress and burnout. An analysis of teacher responses using hierarchical regression revealed that pedagogical barriers had significant positive effects on the burnout dimensions. Furthermore, the results show not only the moderator role played by coping strategies in the pedagogical barriers-burnout dimensions relationship, but also the association between self-efficacy and the coping strategies used by teachers. Practical implications are discussed.     

Brief version of the Fear of Negative Evaluation Scale - Straightforward Items (BFNE-S): psychometric properties in a Spanish population

The aim of this study was to examine the psychometric properties of the Brief version of the Fear of Negative Evaluation Scale - Straightforward Items (BFNE-S) in a non-clinical Spanish population. Rodebaugh et al. (2004) recommend the use of this scale composed of 8 straightforwardly-worded items, instead of the 12-item version of the BFNE. The sample consisted of 542 undergraduate students, 71.3% of whom were women and 28.7% were men; the mean age was 21.71 (4.78) years. Exploratory factor analysis produced one factor which accounted for 51.28% of variance. The internal consistency of the scale was alpha = .89. The BFNE-S correlated with the Social Avoidance and Distress Scale (r = .44), the Personal Report of Confidence as Speaker Modified (r = .44), the Public Speaking Self-Efficacy Questionnaire (r = -.38) and both subscales of the Self-Statements during Public Speaking (SSPS-P r = -.22; SSPS-N r = .53). ANOVAs revealed significant differences in the BFNE-S amongst a non-clinical population, persons suffering from specific social phobia, non-generalized social phobia and generalized social phobia.     

Adaptation of the "Recovery Experience Questionnaire" in a Spanish sample

The aim of this work was to examine the psychometric properties of the Spanish version of the "Recovery Experience Questionnaire" developed by Sonnentag and Fritz. The sample was made up of 941 professionals from the security sector. Results from the exploratory factor analysis suggested the possibility of considering a four-factor structure. Confirmatory factor analysis showed that the four-factor model with three correlated items each provided the best fit to the data (CFI=0.97, GFI=0.96, NNFI=0.96, RMSEA=0.05 y AIC=171.76). Therefore, the questionnaire maintains the four recovery experiences -psychological detachment from work, relaxation, mastery experiences and control over leisure time--but with 12 items instead of 16 items as in the original scale. Reliability analysis showed good internal consistency for this scale with Cronbach alpha coefficients for the factors ranging from .75 to .88. Significant correlations were found between the recovery experiences and various external variables, providing evidence of construct validity. Thus, this Spanish version shows adequate psychometric properties and may help to achieve a better understanding of this topic.     

Development and validation of a questionnaire about the main variables affecting the individual investor's behavior in the Stock Exchange

Development and validation of a questionnaire about the main variables affecting the individual investor's behavior in the Stock Exchange. There is a considerable lack of information about the methodology usually used in most of the studies about individual investor's behavior. The studies reviewed do not show the method used in the selection of the items or the psychometric properties of the questionnaires. Because of the importance of investment in the Stock Exchange nowadays, it seems relevant to obtain a reliable instrument to understand individual investor's behavior in the Stock Exchange. Therefore, the goal of the present work is to validate a questionnaire about the main variables involved in individual investors' behavior in the Stock Exchange. Based on previous studies, we elaborated a questionnaire using the Delphi methodology with a group of experts. The internal consistency (Cronbach alpha=.934) and validity evidence of the questionnaire show that it may be an effective instrument and can be applied with some assurance.     

Physical Oracles: The Turing Machine and the Wheatstone Bridge

Earlier, we have studied computations possible by physical systems and by algorithms combined with physical systems. In particular, we have analysed the idea of using an experiment as an oracle to an abstract computational device, such as the Turing machine. The theory of composite machines of this kind can be used to understand (a) a Turing machine receiving extra computational power from a physical process, or (b) an experimenter modelled as a Turing machine performing a test of a known physical theory T. Our earlier work was based upon experiments in Newtonian mechanics. Here we extend the scope of the theory of experimental oracles beyond Newtonian mechanics to electrical theory. First, we specify an experiment that measures resistance using a Wheatstone bridge and start to classify the computational power of this experimental oracle using non-uniform complexity classes. Secondly, we show that modelling an experimenter and experimental procedure algorithmically imposes a limit on our ability to measure resistance by the Wheatstone bridge. The connection between the algorithm and physical test is mediated by a protocol controlling each query, especially the physical time taken by the experimenter. In our studies we find that physical experiments have an exponential time protocol; this we formulate as a general conjecture. Our theory proposes that measurability in Physics is subject to laws which are co-lateral effects of the limits of computability and computational complexity.     

The Sources and Resources of Our Indigenous Theology

In this article I describe the sources of my indigenous theology out of my own experiences, my worldview, and as a woman. In the first part, I mention our struggles of resistance as the source from which we draw our strength and hopes to resist oppression and dream of a different society, as our ancestors dreamed and acted. I then speak of our living for the day as an act of ideological resistance. It is possible that many readers do not yet understand it, but this involves a worldview different from that of Western capitalism. Some communities in the Amazon still practise this other worldview and take it as their guide. They live day by day, concerned not for the morrow but for the present day; they attempt to live a life of quality, justice and honesty, as if it were the last day of their lives. The source from which our theological enterprise springs is also our wise men and women, who still survive in our communities. They are the guardians of our ancestral wisdom on life, the cosmos and our relations with the created world and its creatures. Moreover, our lifestyle is based on caring for and protecting Pachamama as one of the joint creators with God, who offers us life and enables us to live in the world as brothers and sisters, because we come into being in Pachamama and return to her.     

The distinction between intuition and guessing in the SRT task generation: A reply to Norman and Price

We (Fu, Dienes, & Fu, 2010) investigated the extent to which people could generate sequences of responses based on knowledge acquired from the Serial Reaction Time task, depending on whether it felt subjectively like the response was based on pure guessing, intuition, conscious rules or memories. Norman and Price (2010) argued that in the context of our task, intuition responses were the same as guessing responses. In reply, we argue that not only do subjects apparently claim to be experiencing different phenomenologies when saying intuition versus guess, but also intuition and guess responses are associated with different behaviors. We found that people could control the knowledge when generating responses felt to be based on intuition but not those felt to be pure guessing. We present further evidence here that triplets associated with intuition but not guessing were also processed fluently.
