A test of Suchey-Brooks (pubic symphysis) and Buckberry-Chamberlain (auricular surface) methods on an identified Spanish sample: paleodemographic implications

Forensic Anthropology and Bioarchaeology studies depend critically on the accuracy and reliability of age-estimation techniques. In this study we have evaluated two age-estimation methods for adults based on the pubic symphysis (Suchey-Brooks) and the auricular surface (Buckberry-Chamberlain) in a current sample of 139 individuals (67 women and 72 men) from Madrid in order to verify the accuracy of both methods applied to a sample of innominate bones from the central Iberian Peninsula. Based on the overall results of this study, the Buckberry-Chamberlain method seems to be the method that provides better estimates in terms of accuracy (percentage of hits) and absolute difference to the chronological age taking into account the total sample. The percentage of hits and mean absolute difference of the Buckberry-Chamberlain and Suchey-Brooks methods are 97.3% and 11.24 years, and 85.7% and 14.38 years, respectively. However, this apparently greater applicability of the Buckberry-Chamberlain method is mainly due to the broad age ranges provided. Results indicated that Suchey-Brooks method is more appropriate for populations with a majority of young individuals, whereas Buckberry-Chamberlain method is recommended for populations with a higher percentage of individuals in the range 60-70 years. These different age estimation methodologies significantly influence the resulting demographic profile, consequently affecting the biological characteristics reconstruction of the samples in which they are applied.

Nicaragua en la encrucijada: el liderazgo de Daniel Ortega y su influencia en el sistema político nicaragüense

En noviembre de 2006, Nicaragua se unió a los países latinoamericanos que han apostado por que la izquierda vuelva a gobernar el país. En el presente trabajo sus autoras realizan una reflexión sobre el devenir postrevolucionario en Nicaragua en relación con una de sus figuras claves, Daniel Ortega. Una aproximación personal a uno de los líderes históricos del sandinismo contextualizada con el papel desempeñado por Ortega en la política moderna nicaragüense, considerando que los liderazgos personales están primando en la política nacional frente a las necesidades reales de una sociedad que está atravesando una grave crisis interna.

Lampas y el espíritu de la naturaleza: estudio de la controversia entre Henry More y Robert Hooke

“Lampas y el Espíritu de la Naturaleza” estudia la controvèrsia entre Henry More i Robert Hooke a propòsit de la filosofia mecànica de la naturalesa en el context del pensament filosòfic i científic del segle XVII a Anglaterra, una controvèrsia que malgrat que es pugui considerar obsoleta en la seva forma no ho és en el seu fons, ja que tant les qüestions plantejades per More com les observacions de Hooke són pertinents i no són lluny, mutatis mutandis, de determinats plantejaments del nostre present.

Consens i revolució: Poble i nació a la Barcelona de la Revolució Liberal, 1835-1843

Anàlisi dels deferents discursos de moderats, progressistes i republicans i els usos dels mots “poble” i “nació” durant els anys 1837-1843. L’autor considera que aquesta perspectiva és important per entendre el període, tot i que els recents debats sobre els orígens del nacionalisme a Espanya ho han deixat en un lloc secundari

Anàlisi del fenomen turístic a Ripoll durant el període 1907-1936 a través de revistes històriques de la vila

L’objectiu principal d’aquest estudi és analitzar el fenomen turístic a Ripoll durant els primers anys del segle XX, concretament durant el període 1907-1936, a través de revistes setmanals de Ripoll d’aquesta època, ja que permeten observar què passava en aquells moments a la societat de la vila i com vivia el turisme, si ho veien com un aspecte negatiu o positiu. A més, el període s’ha escollit per veure com era el turisme a inicis del segle XX, però també per veure com va evolucionar i com es va estancar al 1936 amb l’esclat de la Guerra Civil

Security analysts as frame-makers

In this paper we explore the mechanisms that allow securities analysts to value companies in contexts of Knightian uncertainty, that is, in the face of information that is unclear, subject to unforeseeable contingencies or to multiple interpretations. We address this question with a grounded-theory analysis of the reports written on Amazon.com by securities analyst Henry Blodget and rival analysts during the years 1998-2000. Our core finding is that analysts' reports are structured by internally consistent associations that includecategorizations, key metrics and analogies. We refer to these representations as calculative frames, and propose that analysts function as frame-makers - that is, asspecialized intermediaries that help investors value uncertain stocks. We conclude by considering the implications of frame-making for the rise of new industry categories, analysts' accuracy, and the regulatory debate on analysts'independence.

Casado Rigalt, Daniel, 2009: El arqueólogo enamorado. Historia oculta de la arqueología española: de los hallazgos fortuitos a los falsificadores de tesoros. La esfera de los libros, Madrid, 275 pp.

Pyrenae acoge la reseña de una obra divulgativa, que debe ser valorada dentro de ese género. No obstante, su lectura también será útil para cualquier profesional que quiera abrir una cata en el estado de la arqueología peninsular de finales de la primera década del siglo XXI, puesto que la firma un doctor en la materia y no un divulgador procedente de otro campo. El arqueólogo enamorado va precedido de un prólogo escrito con amor por Carmen Rigalt, periodista y madre del autor. Bajo el subtítulo Historia oculta de la arqueología española: de los hallazgos fortuitos a los falsificadores de tesoros, se plantea un proyecto elogiable, que aspira a ofrecer un panorama completo del pasado hispánico, desde la más remota prehistoria a los visigodos, haciendo cuadrar, de forma bastante equilibrada, la amplia geografía peninsular en 14 capítulos y una introducción.

The first SEPServer event catalogue 68-MeV solar proton events observed at 1 AU in 1996-2010

SEPServer is a three-year collaborative project funded by the seventh framework programme (FP7-SPACE) of the European Union. The objective of the project is to provide access to state-of-the-art observations and analysis tools for the scientific community on solar energetic particle (SEP) events and related electromagnetic (EM) emissions. The project will eventually lead to better understanding of the particle acceleration and transport processes at the Sun and in the inner heliosphere. These processes lead to SEP events that form one of the key elements of space weather. In this paper we present the first results from the systematic analysis work performed on the following datasets: SOHO/ERNE, SOHO/EPHIN, ACE/EPAM, Wind/WAVES and GOES X-rays. A catalogue of SEP events at 1 AU, with complete coverage over solar cycle 23, based on high-energy (~68-MeV) protons from SOHO/ERNE and electron recordings of the events by SOHO/EPHIN and ACE/EPAM are presented. A total of 115 energetic particle events have been identified and analysed using velocity dispersion analysis (VDA) for protons and time-shifting analysis (TSA) for electrons and protons in order to infer the SEP release times at the Sun. EM observations during the times of the SEP event onset have been gathered and compared to the release time estimates of particles. Data from those events that occurred during the European day-time, i.e., those that also have observations from ground-based observatories included in SEPServer, are listed and a preliminary analysis of their associations is presented. We find that VDA results for protons can be a useful tool for the analysis of proton release times, but if the derived proton path length is out of a range of 1 AU < s[3 AU, the result of the analysis may be compromised, as indicated by the anti-correlation of the derived path length and release time delay from the asso ciated X-ray flare. The average path length derived from VDA is about 1.9 times the nominal length of the spiral magnetic field line. This implies that the path length of first-arriving MeV to deka-MeV protons is affected by interplanetary scattering. TSA of near-relativistic electrons results in a release time that shows significant scatter with respect to the EM emissions but with a trend of being delayed more with increasing distance between the flare and the nominal footpoint of the Earth-connected field line.

A comparison of three established age estimation methods on an adult Spanish sample.

Most current methods for adult skeletal age-at-death estimation are based on American samples comprising individuals of European and African ancestry. Our limited understanding of population variability hampers our efforts to apply these techniques to various skeletal populations around the world, especially in global forensic contexts. Further, documented skeletal samples are rare, limiting our ability to test our techniques. The objective of this paper is to test three pelvic macroscopic methods (1-Suchey-Brooks; 2- Lovejoy; 3- Buckberry and Chamberlain) on a documented modern Spanish sample. These methods were selected because they are popular among Spanish anthropologists and because they never have been tested in a Spanish sample. The study sample consists of 80 individuals (55 ♂ and 25 ♀) of known sex and age from the Valladolid collection. Results indicate that in all three methods, levels of bias and inaccuracy increase with age. The Lovejoy method performs poorly (27%) compared with Suchey-Brooks (71%) and Buckberry and Chamberlain (86%). However, the levels of correlation between phases and chronological ages are low and comparable in the three methods (< 0.395). The apparent accuracy of the Suchey-Brooks and Buckberry and Chamberlain methods is largely based on the broad width of the methods" estimated intervals. This study suggests that before systematic application of these three methodologies in Spanish populations, further statistical modeling and research into the co-variance of chronological age with morphological change is necessary. Future methods should be developed specific to various world populations, and should allow for both precision and flexibility in age estimation.
