flor de piedra
No full textLa información de esta miniguía se basa a la fecha de publicación de la misma, en los trabajos de los arqueólogos Ticul Alvarez, Oscar J. Polaco, Henry Chapman Mercer, Luis Millet C., Rrcardo Velázquez V., Edward H. Thompson y María Susana Xelhuantz-LópezEtimológicamente la palabra Loltún, compuesta de Lol 'flor' y Tun 'piedra', quiere decir en lengua maya yucateco 'flor de piedra'. En la actualidad las grutas de Loltún son el sitio arqueológico que contiene la más amplia secuencia cronológica en el norte de la península de Yucatán. Por medio de los análisis de los materiales cerámicos, líticos y óseos, se sabe que los primeros cubren un periodo que va desde el año 1000 a.C., hasta el año 1250 d.C., aproximadamente. Los artefactos líticos, que pertenecen al periodo pre cerámico, han sido fechados entre los 9000 y 3000 a.C., aproximadamente, y constituyen la primera evidencia del hombre nómada en la península de Yucatán. Los materiales óseos de fauna pleistocena fueron identificados por el estudio paleontológico, que señala que existieron animales como mastodontes, bisontes, camellos, caballos, y gran variedad de mamíferos, todos ellos ya extintos.</p

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Pavlovian conditioning of muscular responses in chronic pain patients: central and peripheral correlates
No full textA differential conditioning design using an aversive slide as conditioned stimulus (CS+) that was followed by an intracutaneous electric stimulus to the left index finger as unconditioned stimulus (US) and a pleasant slide that was not followed by shock (CS-) were used to test the hypothesis of enhanced aversive conditioning of muscular responses in chronic back pain patients (CBP). Heart rate, skin conductance levels, and integrated surface electromyograms (EMG) from the left and right m. flexor digitorum, the right m. trapezius, and bilaterally from the m. orbicularis oculi were recorded. The electroencephalogram (EEG) was measured from nine electrode positions. The CBP patients showed an enhanced muscular response of the left forearm (where the US was applied) to the CS+ already in the preconditioning phase. During acquisition both the left forearm and the right trapezius of the patients but not the controls displayed enhanced muscular responding to the CS+. During extinction the CBP patients' muscular responses to both CS+ and CS- were elevated. The contingent negative variation of the EEG differentiated between CS+ and CS- in the healthy controls but not the chronic pain patients. These data confirm the hypothesis of enhanced muscular responding in chronic pain patients and suggest a dissociation of muscular and central processes during aversive conditioning in the patients that might contribute to the chronicity problem

Central and peripheral psychophysiological responses to trauma-related cues in subclinical posttraumatic stress disorder: a pilot study.
No full textThis study examined verbal-subjective, peripheral and central physiological responses of motor vehicle accident (MVA) survivors with subclinical posttraumatic stress disorder (PTSD), without PTSD symptoms as well as healthy controls. Seven persons of each group were exposed to positive, neutral, accident-related and negative, non-accident-related slides. The verbal-subjective ratings of the slides did not differ between the groups. In contrast to the verbal ratings of the trauma-related materials, the behavioral and physiological responses showed a remarkable dissociation from these reports. The startle responses were enhanced to accident-related slides only in the PTSD group and MVA survivors with PTSD had a significantly lower response to the neutral slides than MVA survivors without PTSD. P200 was lower to positive, neutral and negative slides in the PTSD group compared to both other groups. The late positive complex showed no group-related effects. The data suggest that traumatized persons with PTSD show exaggerated emotional responses to trauma-related stimuli and reduced cognitive responses to several types of stimuli that may interfere with the extinction of the emotional trauma memory
