Reconocimientos arqueológicos en las subcuencas de los ríos coello y Tetare (Municipios de coello y Piedras-Tolima)
Full text linkEn reconocimientos arqueológicos efectuados entre Jos municipios de Coello y Piedras en el departamento del Tolima, parte baja de las subcuencas de los ríos Coello y Totare, se han hallado varios lugares de interés arqueológico que presentan evidencias con características de diversos períodos históricos. En los yacimientos se han obtenido fragmentos cerámicos y líticos, ubicados en la superficie y en capas estratificadas. Por lo .general los aterrazamientos naturales se encuentran localizados en las márgenes del río Magdalena y en afluentes como el Coello y el Opia. De acuerdo con la tipología cerámica establecida para la- región norte del Alto Magdalena, según las formas y diseños que presentan los fragmentos cerámicos se infieren dos ocupaciones temporalmente diferentes. Se considera la primera como propia del Formativo Tardío o de los Desarrollos regionales y la segunda ocupación se identifica como Tardía cercana a la conquista.Mediante los reconocimientos se diferencian dos posibles pautas de ocupación caracterizadas por estar ubicadas en terrazas próximas a las riberas del río Magdalena y a cauces tributarios de los ríos Bogotá, Coello, Opia y Totare. Dicha pauta corresponde así mismo a otros sectores del Valle del Magdalena que se han estudiado con anterioridad en diversos proyectos cercanos a ríos como el Gualí, Sabandija, sumapaz, Luisa y Saldaña. En este tramo de la cuenca del río Coello los sitios establecidos como propios al Formativo Tardío se ubican en terrazas altas (500 m.s.n.m.) con relación al cauce del río Magdalena y las consideradas Tardías en terrazas de menor altura (300 m.s.n.m.}, localizadas por lo general en las márgenes del río coello

Embodied perception of reachable space: how do we manage threatening objects?
No full textThis study aimed at determining whether the size of reachable space is affected by the level of danger of some everyday manipulable objects. Two possibilities are examined: Dangerous objects affect the size of reachable space because of long-term semantic knowledge of their potential hurtful value or the on-line relation between objects’ dangerous attributes and the body. The experimental paradigm combined the danger value (dangerous/not dangerous) and the orientation of objects (e.g. pointing away from/towards the perceiver). Reachability judgments measured the size of peripersonal space, and perception of objects’ danger was estimated through questionnaires. Results revealed that, whatever the estimated level of objects’ danger, the extent of peripersonal space was reduced when the threatening part of dangerous subjects was oriented towards participants, not when oriented away. This suggests that the characteristics of the here and now body-objects interaction are crucial in affecting the boundary of peripersonal space

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Defensive functions provoke similar psychophysiological reactions in reaching and comfort spaces
No full textThe space around the body crucially serves a variety of functions, first and foremost, preserving one’s own safety and avoiding injury. Recent research has shown that emotional information, in particular threatening facial expressions, affects the regulation of peripersonal-reaching space (PPS, for action with objects) and interpersonal-comfort space (IPS, for social interaction). Here we explored if emotional facial expressions may similarly or differently affect both spaces in terms of psychophysiological reactions (cardiac inter-beat intervals: IBIs, i.e. inverse of heart rate; Skin Conductance Response amplitude: SCR amplitude) and spatial distance. Through Immersive Virtual Reality technology, participants determined reaching-distance (PPS) and comfort-distance (IPS) from virtual confederates exhibiting happy/angry/neutral facial expressions while being approached by them. During these interactions, spatial distance and psychophysiological reactions were recorded. Results revealed that when interacting with angry virtual confederates the distance increased similarly in both comfort-social and reaching-action spaces. Moreover, interacting with virtual confederates exhibiting angry rather than happy or neutral expressions provoked similar psychophysiological activations (SCR amplitude, IBIs) in both spaces. Regression analyses showed that psychophysiological activations, particularly SCR amplitude in response to virtual confederates approaching with angry expressions, were able to predict the increase of PPS and IPS. These findings suggest that self-protection functions could be the expression of a common defensive mechanism shared by social and action spaces
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
