Capacitación turística en comunidades indígenas. Un caso de Investigación Acción Participativa (IAP)

La literatura académica subraya la importancia de involucrar a la comunidad en los procesos de capacitación turística. Sin embargo, apenas hay reflexiones sobre cómo diseñar e implementar la formación en áreas rurales y remotas. En este trabajo se exponen las cuatro fases de un ciclo de Investigación Acción Participativa (IAP), desarrollada en la Selva Lacandona de México con la colaboración de los grupos originarios lacandones y ch’oles. El objetivo de estudio fue la capacitación humana en las áreas de sistemas turísticos, interpretación del patrimonio natural y cultural, y creación de producto. Todo ello complementado con una capacitación específica para mujeres y jóvenes, grupos tradicionalmente relegados en estas comunidades. El relato de las distintas fases de la IAP nos muestra cómo el conocimiento ancestral es la base para una capacitación turística sólida. La involucración de jóvenes estudiantes en los procesos de formación en comunidades, los formatos adaptados a los contextos locales, y los ejercicios de reciprocidad científica, sirven además para la revitalización cultural, el refuerzo de la autoestima y el desarrollo endógeno de los pueblos indígenas.

Co-design: setting relational domains for deep sustainability

This paper draws mainly on the work of Elizabeth Sanders who has being practising, thinking and mapping participatory design research for over 25 years, connecting it to insights from Maturana (1984), Capra (2002), Jovchelovitch (1995, 2000, 2007) and Preece (2011), to propose that the process of design per se is a relational domain of cocreativity that is essential to construct a way toward deeper sustainability.

Gray's Reinforcement Sensitivity Theory: a psychometric critique

This study identifies valid orthogonal scales of Gray's animal learning paradigms, upon which his Reinforcement Sensitivity Theory (RST) is based, by determining a revised structure to the Gray-Wilson Personality Questionnaire (GWPQ) (Wilson, Gray, & Barrett, 1990). It is also determined how well Gray's RST scales predict the surface scales of personality, which were measured in terms of Eysenck Personality Profiler (EPP) scales, the EPQ-R and the learning styles questionnaire (LSQ) scales. First, results suggest that independent pathways of RST scales may exist in humans. Second, Fight seems related to Anxiety and not the Fight/Flight system as proposed by RST. Third. a remarkably consistent story emerges in that Extraversion scales are predicted by Fight, Psychoticism scales are predicted by Active-avoidance, Fight and/or Flight, and Neuroticism scales tend not to be predicted at all (except for Anxiety). Fourth, Gray's revised scales are Unrelated to gender and age effects and show a predictable overlap with the LSQ and original GWPQ scales. It is concluded that Gray's model of personality might provide a stable biological basis of many surface scales of personality, but that there must also be other influences on personality. These results question the finer structure of Gray's RST whilst also showing that RST has greater range of applicability than a strict interpretation of theory implies. (C) 2002 Elsevier Science Ltd.

Gray's model of personality and aggregate level factor analysis

Previous research shows that correlations tend to increase in magnitude when individuals are aggregated across groups. This suggests that uncorrelated constellations of personality variables (such as the primary scales of Extraversion and Neuroticism) may display much higher correlations in aggregate factor analysis. We hypothesize and report that individual level factor analysis can be explained in terms of Giant Three (or Big Five) descriptions of personality, whereas aggregate level factor analysis can be explained in terms of Gray's physiological based model. Although alternative interpretations exist, aggregate level factor analysis may correctly identify the basis of an individual's personality as a result of better reliability of measures due to aggregation. We discuss the implications of this form of analysis in terms of construct validity, personality theory, and its applicability in general. Copyright (C) 2003 John Wiley Sons, Ltd.

The personality profile of female Anglican clergy in Britain and Ireland: A study employing the Eysenck Personality Profiler

A sample of 523 newly ordained female Anglican clergy in England, Ireland, Scotland and Wales completed the Eysenck Personality Profiler (EPP). The data demonstrated that the female clergy tended to be less extravert than women in general, less neurotic than women in general, and less toughminded than women in general. These findings help to clarify the way in which women clergy tend to project a characteristically masculine personality profile in respect of one major dimension of personality (neuroticism), but a characteristically feminine personality profile in respect of the other two major dimensions of personality (psychoticism and extraversion).

Evaluation of individual protein errors in silver-stained two-dimensional gels

The relationship between spot volume and variation for all protein spots observed on large format 2D gels when utilising silver stain technology and a model system based on mammalian NSO cell extracts is reported. By running multiple gels we have shown that the reproducibility of data generated in this way is dependent on individual protein spot volumes, which in turn are directly correlated with the coefficient of variation. The coefficients of variation across all observed protein spots were highest for low abundant proteins which are the primary contributors to process error, and lowest for more abundant proteins. Using the relationship between spot volume and coefficient of variation we show it is necessary to calculate variation for individual protein spot volumes. The inherent limitations of silver staining therefore mean that errors in individual protein spot volumes must be considered when assessing significant changes in protein spot volume and not global error.

Strategic interventions in intellectual asset flows

The rise of the knowledge economy brings to the foreground questions of how firms might best capture the value of their intellectual assets. In this article I introduce the notion of strategic interventions in intellectual asset flows designed to influence the level and composition of intellectual asset scarcity, with implications for firm performance. I also present propositions that explain and predict how contingencies at differing levels of analysis influence the choice of strategic intervention.

5 '-Untranslated regions with multiple upstream AUG codons can support low-level translation via leaky scanning and reinitiation

Upstream AUGs (uAUGs) and upstream open reading frames (uORFs) are common features of mRNAs that encode regulatory proteins and have been shown to profoundly influence translation of the main ORF. In this study, we employed a series of artificial 5'-untranslated regions (5'-UTRs) containing one or more uAUGs/uORFs to systematically assess translation initiation at the main AUG by leaky scanning and reinitiation mechanisms. Constructs containing either one or two uAUGs in varying contexts but without an in-frame stop codon upstream of the main AUG were used to analyse the leaky scanning mechanism. This analysis largely confirmed the ranking of different AUG contextual sequences that was determined previously by Kozak. In addition, this ranking was the same for both the first and second uAUGs, although the magnitude of initiation efficiency differed. Moreover, similar to10% of ribosomes exhibited leaky scanning at uAUGs in the most favourable context and initiated at a downstream AUG. A second group of constructs containing different numbers of uORFs, each with optimal uAUGs, were used to measure the capacity for reinitiation. We found significant levels of initiation at the main ORF even in constructs containing four uORFs, with nearly 10% of ribosomes capable of reinitiating five times. This study shows that for mRNAs containing multiple uORFs/uAUGs, ribosome reinitiation and leaky scanning are efficient mechanisms for initiation at their main AUGs.

Global changes in gene expression observed at the transition from growth to stationary phase in Listeria monocytogenes ScottA batch culture

Listeria monocytogenes is a food-borne Gram-positive bacterium that is responsible for a variety of infections (worldwide) annually. The organism is able to survive a variety of environmental conditions and stresses, however, the mechanisms by which L. monocytogenes adapts to environmental change are yet to be fully elucidated. An understanding of the mechanism(s) by which L. monocytogenes survives unfavourable environmental conditions will aid in developing new food processing methods to control the organism in foodstuffs. We have utilized a proteomic approach to investigate the response of L. monocytogenes batch cultures to the transition from exponential to stationary growth phase. Proteomic analysis showed that batch cultures of L. monocytogenes perceived stress and began preparations for stationary phase much earlier (approximately A(600) = 0.75, mid-exponential) than predicted by growth characteristics alone. Global analysis of the proteome revealed that the expression levels of more than 50% of all proteins observed changed significantly over a 7-9 h period during this transition phase. We have highlighted ten proteins in particular whose expression levels appear to be important in the early onset of the stationary phase. The significance of these findings in terms of functionality and the mechanistic picture are discussed.

Transgenic mice that express Cre recombinase in osteoclasts

To study the physiological control of osteoclasts, the bone resorbing cells, we generated transgenic mice carrying the Cre recombinase gene driven by either the tartrate-resistant acid phosphatase (TRAP) or cathepsin K (Ctsk) promoters. TRAP-Cre and Ctsk-Cre transgenic mouse lines were characterized by breeding with LacZ ROSA 26 (R26R) reporter mice and immunohistochemistry for Cre recombinase. The Cre transgene was functional in all lines, with Cre-mediated recombination occurring primarily in the long bones, vertebrae, ribs, and calvaria. Histological analyses of the bones demonstrated that functional Cre protein was present in 1) osteoclasts (Ctsk-Cre); 2) osteoclasts, columnar proliferating, and hypertrophic chondrocytes (TRAP-Cre line 4); and 3) round proliferating chondrocytes (TRAP-Cre line 3). In conclusion, we generated transgenic mouse lines that will enable the deletion of floxed target genes in osteoclasts, which will be valuable tools for studying the regulation of osteoclast function.

A full cost environmental accounting experiment

A lack of appropriate measurement techniques has constrained full cost environmental accounting (FCEA) experimentation. Yet, there has been little research on the applicability of valuation techniques recently developed by environmental economists within FLEA frameworks. This paper examines a reporting experiment using these valuation techniques that was undertaken by an Australian Government Department managing publicly owned forests. The FCEA experiment was ultimately not successful. However, the implementation experiences of the Department including the reactions of its managers and stakeholders provide an opportunity to critically reflect on the experimental outcomes to extend the current empirical knowledge of corporate social responsibility reporting. Such critical reflection has not been common in past FCEA experimentation. © 2005 Elsevier Ltd. All rights reserved.
