Editorial: 25 años de evaluación por pares en Trabajos de Prehistoria

This editorial closes the four-year term of the current Editorial Board. It presents the contents of volume 75, the 25th since Trabajos de Prehistoria became a semestral peer-reviewed journal. Both numbers of vol. 75 combine articles accepted in the course of normal business with invited manuscripts. The latter address the current state of prehistoric research in the Iberian Peninsula as seen from abroad, as well as presenting the results of major projects carried by prehistorian of the Institute of History in the Spanish National Research Council. It assesses the degree of professionalism and the international impact of the work that falls within the journal’s scope of interest. The volume is dedicated to its founder, Martín Almagro Basch.El editorial cierra el cuatrienio del actual equipo. Presenta el contenido del volumen 75, dedicado a Martin Almagro Basch, fundador de Trabajos de Prehistoria, cuando se conmemoran los 25 años de la evaluación por pares en la revista. Cada número semestral combina artículos resultantes de la gestión habitual de la revista con otros invitados. Estos abordan el estado actual de la investigación prehistórica en la Península Ibérica, visto desde el extranjero, y proyectos importantes llevados a cabo por los prehistoriadores del Instituto de Historia del Consejo Superior de Investigaciones Científicas (CSIC). Se valora el grado de profesionalidad e internacionalización que han adquirido los estudios enmarcados en las líneas editoriales de Trabajos de Prehistoria

Cómo valorar los sistemas de propiedad a partir de datos arqueológicos

Processual archaeologists have been reluctant to address the nature of prehistoric property regimes. Ethnological evidence suggests a predictable development of such regimes over the evolutionary range of human societies. Examination of patterns of elite expenditure and household consumption can be used to evaluate such evolutionary scenarios in concrete cases.Los arqueólogos procesuales han sido remisos a ocuparse de la naturaleza de los regimenes prehistóricos de propiedad. La evidencia etnológica sugiere un desarrollo predecible de tales regimenes en el curso de la escala evolutiva de las sociedades humanas. El examen de los patrones relativos a los gastos de la elite y del consumo familiar puede usarse para evaluar tales escenarios evolutivos en casos concretos

Notas sobre la trayectoria científica de Mª. Dolores Fernández-Posse

The scholarly trajectory of Mª Dolores Fernández- Posse involved an ongoing process of critical observation, reflection, and change that is quite rare in Archaeology. Her change from normativism to a historically informed functionalism is representative of the general evolution of Spanish archaeological studies over the course of the past thirty years. What is unusual about Fernández-Posse -and attests to her straightforward and unassuming intelligence- is that she herself changed her mind and voiced that change with clarity and humor.La trayectoria científica de Mª Dolores Fernández-Posse se caracterizó por un proceso continuo de observación crítica, reflexión y cambio, algo poco común en Arqueología. Su cambio del normativismo a un funcionalismo de orientación histórica es representativo de la evolución de los estudios arqueológicos en España a lo largo de los últimos treinta años. Lo realmente inusual de Fernández-Posse -y lo que atestigua su directa pero no pretenciosa inteligencia- es que ella misma cambió de ideas y publicitó ese cambio con claridad y humor

Cambio cultural y contacto en la Prehistoria de la Europa mediterránea

The historically documented importance of seafaring commerce has served as a charter for the interpretation of Mediterranean prehistory. Within the normativist framework that prevailed until recently, any similarity in the particulars of archaelogical assemblages could be proof of a commerce of ideas. By limiting the notion of commerce t0 quantifiable exchanges, processualists have argued for the autonomous development of each region within the prehistoric Mediterranean, a perhaps excessively restricted view. World-systems approaches offer the opportunity to give processual weight to intersocietal contacts, but only are successful when the social and economic structure of both center and periphery is adequately understood.La importancia del comercio marítimo en épocas históricas ha servido como modelo para la interpretación de la prehistoria mediterránea. Para los normativistas que prevalecieron hasta recientemente, cualquier parecido particular entre conjuntos arqueológicos podría ser prueba de un comercio de ideas. Al restringir el término comercio a intercambios cuantificables, los procesualistas han sostenido que el desarrollo prehistórico de cada región del Mediterráneo era autónomo, un punto de vista quizás demasiado limitado. Los enfoques de tipo sistema mundial brindan la oportunidad de dar un peso procesual a los contactos entre las sociedades, pero sólo funcionan cuando hay una valoración adecuada de la estructura social y económica tanto del centro como de la periferia

Bioimpedance markers and tuberculosis outcome among HIV-infected patients

ackground: The changes in body composition markers (weight, fat mass, lean mass, and BMI) over time can be associated with TB treatment outcome among HIV-infected patients. The aim of this study was to investigate whether changes in fat mass and lean mass were associated with the treatment response among patients with HIV infection and pulmonary tuberculosis. Materials and Methods: This was a prospective cohort study. Data from HIV-infected patients commencing TB therapy were analyzed. This included body weight measurement using bioimpedance equipment at baseline, one month, and two months after starting TB treatment. Results: The study was conducted in 125 patients, 17 patients (13.6%) died during treatment, of which 5 died during the first month of treatment, 4 during the second month and 8 after the second month. The group of patients with good response, increased their weight by 1.3 kg (p <0.001) at the end of the first month of TB treatment and 2.6 kg in the second month (p <0.001), and body fat increase was 1.2 Kg (p <0.001) and 2.3 kg (p <0.001), the first and second month respectively. The group of patients who died had lost 2.1 kg fat mass after the first month (p <0.001) and 3.7 kg in the second month (p <0.001). Conclusions: Our results show that the weight change during TB treatment (increased fat mass) helps us predict therapeutic response. Weight loss during the first month of starting therapy should be evaluated thoroughly to identify the probable cause of treatment failure.Revisión por pare

Rural-to-Urban Migration: Socioeconomic Status But Not Acculturation was Associated with Overweight/Obesity Risk.

To investigate whether socioeconomic status (SES) and acculturation predict overweight/obesity risk as well as the mediating effect of physical activity (PA) in the context of internal migration. Cross-sectional study of 587 rural-to-urban migrants participating in the PERU MIGRANT study. Analyses were conducted using logistic regression and structured equation modeling. Interaction effects of SES and acculturation were tested. Models were controlled for age, gender and education. Only SES was a significant predictor of overweight/obesity risk. Lower SES decreased the odds of being overweight/obese by 51.4 %. This association did not vary by gender nor was it explained by PA. Mechanisms underlying the relationship between SES and overweight/obesity may differ depending on the geographic location and sociocultural context of the population studied. Research on internal migration and health would benefit from the development of tailored acculturation measures and the evaluation of exploratory models that include diet
