Authors: Castro-Sánchez Manuel , Linares-Manrique Marta , Sanromán-Mata Silvia , Pérez Cortés Antonio José
Published: June 2017

El aumento de las conductas sedentarias en la sociedad actual representa uno de los principales problemas de salud del siglo XXI, agravado por el creciente uso e incorporación a la vida diaria de las nuevas tecnologías y un aumento del abandono de la práctica deportiva. Se plantea como objetivo, determinar las conductas sedentarias y de ocio digital en una población de estudiantes de Educación Primaria, Secundaria y Universidad, así como establecer las posibles relaciones existentes entre las variables. Participaron 155 estudiantes de 10 a 28 años (M=15,75 años; DT= 4,420), en la presente investigación que utilizó un diseño descriptivo y de corte transversal. Los adolescentes  respondieron a un cuestionario de elaboración ropia que contenía ítems de tipo sociodemográfico, físico-deportivo y de ocio digital. Como principales resultados podemos señalar que la mayoría de los sujetos ven la televisión menos de dos horas diarias; la mitad de la muestra no practica actividad física, encontrando que en la etapa universitaria se percibe un descenso con respecto a las otras etapas; los estudiantes de Primaria dedican más tiempo a jugar a videojuegos que en las etapas Secundaria y Universidad. Todos estos datos nos indican lo necesario de implementar programas de promoción de actividad física habitual en detrimento de las conductas sedentarias.

Published: June 2017

La adolescencia es un periodo clave en el inicio del consumo de sustancias nocivas y la adquisición de conductas dañinas, como el consumo de alcohol y tabaco, por ello el presente estudio tiene como objetivo analizar el consumo de estas sustancias en relación con la práctica de actividad física de los adolescentes y establecer las relaciones existentes entre las variables. Participaron 2.134 estudiantes de edades comprendidas entre los 15 y los 18 años (M=15,93 años), que permitió el registro y evaluación de las variables Consumo de Tabaco “Fagerström Test for Nicotine Dependence (FTND)”, Consumo de Alcohol “Alcohol Use Disorders Identification Test (AUDIT)” y Actividad física. Los resultados mostraron que nueve de cada diez adolescentes no son fumadores y tres de cada diez bebían alcohol; las chicas predominan en el consumo de alcohol de forma moderada, frente a los chicos, que lo hacen en forma excesiva. Casi siete de cada diez adolescentes practica actividad física de forma extraescolar, frente a un tercio que no practica. Ser físicamente activo está relacionado con no ser fumador o serlo en menos cantidad, pero no hay relación entre consumir alcohol y ser físicamente activo.

A study to find the causes of diabetic foot infections in a selected community
Authors: Pallela Someshwara Rao Narayana , Narahari Padmavathi
Published: June 2017

Background: Ulcerations associated with diabetes are the most common cause of foot infections. Most of these ulcers are a direct result of loss of sensation secondary to peripheral neuropathy. The prevalence of leg ulceration is approximately 1% to 2%, and is slightly higher in the older adult population. Venous ulcers are the most common form of leg ulcers, accounting for almost 80% of all lower extremity ulcerations. Peak prevalence is between 60 and 80 years. Approximately one third of patients with chronic venous insufficiency will develop venous ulceration before the age of 40 years. In addition, venous ulcers may have a prolonged duration and are associated with a high rate of recurrence, which contributes to their prevalence. Approximately 15% of persons with diabetes will develop foot ulceration during their lifetime. Most lower extremity amputations in India are preceded by a foot ulcer. This study is done to find the commonest causes of foot infection in the background of neuropathy among the selected population.Methods: Total of 153 patients were included in this study. Detailed history was taken and all the wounds were classified according to Wagner’s grades. Foot infections in the grade 3,4, 5 (which required debridement/amputations) were included in the study. Foot ulcerations without infections were excluded from the study.Results: 142 (92%) of the patients with infection had diabetic neuropathy. All patients with diabetic neuropathy presented with sensory neuropathy. 33 (21%) patients presented with infection due to previous callus. 52 (33%) patients presented with infection due to previous non-healing ulcer. 20 (13%) patients with deformities developed callus at bony pressure areas due to neuropathy or post-surgery sequel. One patient had hot water burns injury. Five (0.03%) patients had Ingrown nails. 14 (0.09%) patients related to barefoot walking/thorn prick injuries. 6 (0.03%) patients had fungal infection. Two (0.01%) patients had itching and scratching over legs. 15 (0.09%) patients had history of previous amputation. Vigorous massage was the cause in 1 patient (0.006%). Shoe bite injury resulted in foot ulcer in 2 (0.02%) patients. Two (0.02%) patients presented with infection due to deep cracks in heels.Conclusions: Neuropathic changes is the most common cause of diabetic foot infections among which callus, non-healing trophic ulcer and previous amputee are the predominant causes. Patient education has a crucial role in prevention of diabetic foot infections by foot care precautions.

Authors: V. Arunagirinathan , S. Stalin , E. Narayanan
Published: June 2017

Background: Empyema thoracis (ET) is serious complication of pneumonia in children, treatment outcome depends upon many risk factors. Empyema thoracis is a serious infection of the pleural space. Despite the availability of broad spectrum antibacterial, improved vaccination coverage and better diagnostic tools, ET remains associated with high morbidity worldwide. This study was undertaken to identify risk factors associated with poor outcome and to describe etiological agents.Methods: This nested case control study was conducted at Institute of Child Health and Hospital for Children, Egmore, and Chennai from January 2011 to October 2012 in age group from 1 month to 12 years attending with clinical/radiological evidence of empyema. Cases children with complications and controls without complications. Basic investigations, ultrasonogram chest, pleural fluid gram stain/ culture and blood culture done. Antibiotics started empirically and changed based on culture and sensitivity. Intercostal drainage (ICD) was inserted with an underwater seal.  Demographic data and other variables analysed were haemoglobin, persistent positive CRP, serum albumin level, pleural fluid gram stain, culture and sensitivity, imaging like ultra-sonogram, CECT, X-ray chest after ICD insertion.Results: Of 90 empyema cases, 26 recovered without complication, 56 recovered with complication, 8 died. Logistic regression uses to find association between variables and complications. Risk factors significantly associated with complications were persistent positive CRP, pleural fluid gram stain, imaging ultra-sonogram chest showing loculations, CECT scan showing pleural thickening and X-ray chest after ICD insertion.Conclusions: Independent risk factors associated with complications were X-ray chest after ICD insertion showing non-resolution, ultrasonogram revealing loculations and septations. Early diagnosis, appropriate antibiotics and timely intervention helps in reduction of empyema and complications.

Published: June 2017

Background: Hypertension is considered as a major health issue in developed as well as developing countries and its possible origin during childhood prompts pediatricians to routinely include measurement of blood pressure (BP) as an integral part of pediatric physical examination. The objectives of the study were to evaluate the normal range of blood pressure in adolescent school going students of 12-16 years, prevalence of hypertension and relationship of BP with variables like age, body mass index (BMI), socioeconomic status and family history of hypertension.Methods: A cross sectional study was undertaken for a period of one year in adolescent school children in age groups between 12-16 years. Detailed clinical examination was done in 1060 adolescent school children and BP was recorded in right upper limb and correlation of BP with BMI, family history of hypertension and diabetes were studied.Results: Mean systolic and diastolic pressure showed linear relationship with age. There was a highly statistically significant difference between mean systolic and diastolic blood pressure between lower and middle socio-economic class. Prevalence of obesity in our study was 1.13%, overweight was 7.83%. Prevalence of hypertension in obese children was 33.33% and in overweight children 18.07%. Family history of hypertension and diabetes carry a significant correlation with elevated systolic and diastolic blood pressure in adolescents.Conclusions: This study revealed that socio economic factors play a significant role in determining the blood pressure of the individual. Children of middle class have significantly elevated mean systolic pressure and mean diastolic pressure than low socio-economic groups.

Published: June 2017

Background: To study the electroencephalographic abnormalities and imaging profile of 60 children suffering from neurocysticercosis at a tertiary care centre over a period of two years.Methods: A diagnosis of Neurocysticercosis was made mainly on the basis of clinical features, imaging studies and serological tests. Patients were evaluated for different types of abnormalities on electroencephalogram (EEG) of their brains. This study group was subsequently evaluated for nature, type and site of lesion on computed tomographic scan and Magnetic Resonance Imaging of brain.Results: 28 (57.14%) cases had abnormal EEG finding in which nonspecific background changes was the commonest abnormalities. Solitary lesion (71.66%) were most common type of lesion. Parietal lobe was most common affected lobe followed by frontal lobe (18.6%). Transitional lesion (71.66%) in the form of ring enhancement following contrast administration was the prominent nature of lesion.Conclusions: Electroencephalographic abnormalities are not directly related to site and type of involvement. Parietal lobe was the most common affected lobe probably due to middle cerebral artery involvement.

Authors: B. A. Girisha , P. Rajesh , C. Satish Kumar , N. Muralidhar
Published: June 2017

Background: Incidence of proximal tibial fractures is increasing due to increasing incidence of road traffic accidents (RTA). Knee joint being one of the major weight bearing joint of the body, appropriate management of fracture around it will be of paramount importance in maintaining mobility. The recent development of locking compression plate (LCP) has revolutionized the treatment of proximal tibial fractures by overcoming the few drawbacks of conventional buttress plate.

Methods: We studied 30 patients involving proximal tibial fracture manged using LCP [23 patients with minimally invasive plate osteosynthesis, (MIPO) technique and 7 patients with Open reduction and internal fixation (ORIF) technique]. We followed up all the patients until complete union of fractures.

Results: The average time for union of fracture was 14 weeks (range: 12-24 weeks). Overall 96.7% patients had acceptable outcome (70% excellent and 26.7% good). Patients treated with MIPO technique healed earlier and more frequently had excellent results than those treated with ORIF. A total of four patients had complications (knee joint stiffness in 1, postoperative loss of reduction in 1, infection in 1 and knee instability in 1).

Conclusions: Locking compression plate system acts as a good biological fixation for proximal tibial fractures even in difficult fracture situations. MIPO technique offers faster healing and better outcome than ORIF in patients with proximal tibial fractures.
Information control system for space experiments onboard international space station
Authors: Voronin F. A. , Dunaeva I. V.
Published: June 2017

The paper considers development of the Information Control System (ICS) of the Russian Segment of the International Space Station (ISS). The main ICS modules for carrying out scientific experiments comprise the Service Module, the Multipurpose Laboratory Module and the Science Power Module. At present specialists of Energia RSC are working to create high-tech conditions for scientific experiments on the new ISS modules, modernize the existing ones and combine them into a single onboard ISS information control complex. The information control system (ICS) is intended for automatic and manual control of space experiments. The effectiveness of modernization was confirmed by the results obtained during space experiments on the basis of the Information Control System. The ICS modernization started in 2012. At that time the ICS consisted of 4 onboard computers. The main task of ICS modernization was to introduce new computers and software-hardware systems. The software was supposed to have a flexible architecture and provide resources for all future onboard payloads. At the first stage one onboard computer was replaced. The main purpose of that stage was to test the new ISS hardware and software. The rest of the ICS computers will be replaced at the second stage, the Multipurpose Laboratory Module and the Science Power Module will also be equipped. The reliability of the system hardware is improved using functional backup. In 2014 2 cameras were installed on the ISS together with UrtheCast company (Canada).One of the cameras is a middle resolution camera; the other one is a high resolution camera. Today ground preparation of an experiment with Icarus scientific equipment is being carried out, jointly with the German Center of Aviation, DLR, and the SpaceTech company (Germany). The experience of the first stage of modernization suggests that the modernized ISS RS ICS will become an up-to-date system allowing the realization of most ambitious space experiments in automatic mode.
Frequency characteristics of a coaxial gas damper for booster feed line
Authors: Odinokov D. A. , Gimadiyev A. G.
Published: June 2017

In development and maintenance of liquid rockets it is essential to ensure its stability in relation to longitudinal oscillations of the body (longitudinal stability, pogo effect) for all possible disturbances. It is known that one of the most effective ways to ensure the longitudinal stability is to use gas dampers-accumulators installed in the feed line at the engine inlet. The damper in the feed line produces additional compliance, thus making it possible to eliminate the coincidence of the fundamental natural frequency of the pressure fluctuations in the feed line and the natural frequencies of the rocket body, which is necessary for providing the longitudinal stability. The damper parameters are selected on the basis of mathematical modeling and experimental data. In this paper, a nonlinear mathematical model of a coaxial gas damper is developed with the use of the ideal-gas law equation for an adiabatic process and the Bernoulli and Saint-Venant Vantsel equations. The mathematical model is used to calculate the frequency characteristics of the damper in the form of input acoustic conductance. The results obtained make it possible to take into account the contribution of passage sections of the throttles to the performance of the damper at the design stage, as well as to select its parameters in simulating processes in the feed lines to solve the longitudinal stability problem.

Published: June 2017

The paper deals with the problem of determining the optimum amount of technological resources of a hub functional subsystem, performing ground handling of aircraft (AC) for purposes of a chosen process step. A simulation model is proposed to be used for the optimization. The simulation model takes into account the peculiarities of the hub work activity and includes a fuzzy controller (FC) that reflects the logic of the airport controller who manages the process of aircraft ground handling. A model example of the solution of an optimization problem is presented. The example indicates the possibility and feasibility of using a fuzzy controller to model a human operators strategy.
POLÍTICAS LINGUÍSTICAS EDUCATIVAS: EFEITOS DA CONTEMPORANEIDADE
Authors: Day Kelly Cristina Nascimento
Published: June 2017

As transformações tecnológicas transcorridas na passagem do século XX para o XXI, modificando profundamente os modos de comunicar entre os indivíduos « intra » e « inter » nacionalmente e, por conseguinte, o papel das línguas no mercado de trabalho global, estão refletidas nas políticas linguísticas em curso na atualidade. Tais políticas encontram-se circunscritas por diversos fatores que não são apenas mercadológicos, exigindo uma observação criteriosa por parte dos agentes político-linguísticos e avaliadores. A proposta deste trabalho é delinear os principais viéses de debate em torno da política linguística educativa nos dias atuais e estabelecer os diferentes focos de discussão. Nossa análise busca situar políticas periféricas, não hegemônicas que confrontam a ideologia da prevalência de políticas globais sobre as locais e refletir sobre as repercussões destas políticas no âmbito de objetivos educacionais que vislumbrem os ideais do plurilinguismo, da tolerância e do respeito à diversidade cultural.
Znaczenie benchmarkingu w działalności innowacyjnej przedsiębiorstw turystycznych na przykładzie Polskich Linii Lotniczych LOT SA
Authors: Gierczak-Korzeniowska Beata
Published: June 2017

Celem artykułu jest identyfikacja znaczenia benchmarkingu jako źródła innowacji w działalności przedsiębiorstw turystycznych na przykładzie Polskich Linii Lotniczych LOT. Uszczegółowieniem tego celu jest wskazanie działów firmy, które wykorzystały metodę w poszukiwaniu impulsów rozwojowych do stworzenia nowej lub ulepszenia dotychczasowej oferty. Podmiotem badań była linia lotnicza należąca do Star Alliance oraz pracownicy wybranych działów w liczbie 27. W ramach badań zastosowano metodę ankietową oraz – tylko w odniesieniu do kierowników wybranych działów – metodę wywiadu jawnego standaryzowanego. Przy analizie danych wykorzystano metody wnioskowania statystycznego, m.in. test niezależności chi-kwadrat. Mimo że wprowadzenie benchmarkingu w struktury przedsiębiorstwa pozwala na szybkie wyrwanie się z kręgu ograniczeń własnej kultury i standardowych zachowań, a zdobywanie wiedzy w trakcie tego procesu daje podstawę do nowych, innowacyjnych pomysłów, to znaczenie metody w działalności innowacyjnej omawianego przedsiębiorstwa nie znajduje odzwierciedlenia w jej praktycznym zastosowaniu. Zauważalny jest przede wszystkim brak wiedzy na temat benchmarkingu, a utożsamianie metody ze zwykłą analizą konkurencji jest skutkiem niepowodzeń i braku kreatywności w jej stosowaniu.

Authors: Duhan* Savita , Sheokand Sunita , Kumari Anita , Sharma Nidhi
Published: June 2017

Four pigeon pea genotypes (ICPH-2431, PARAS, UPAS-120, H09-33) were raised in polythene bags filled with half kg soil + FYM manure mixture. Waterlogging, salinity and waterlogging + salinity treatments were given for 8 days and observations were recorded 1 day after removal from treatment in 20 and 40 day old plants. Significant decline in percent survival was observed under waterlogging and combined treatment in 20 and 40 day old plants. Decline in total sugar content and non reducing sugar content was observed under all three treatments in 20 and 40 day old plant leaves. In roots, an initial increase in total soluble sugar content was observed with waterlogging and salinity treatment. Non reducing sugar content also decreased under all the three treatments. An increase in sucrose synthase and alcohol dehydrogenase activity under all three treatments and formation of aerenchyma in roots under waterlogging and combined treatment was also observed. Waterlogging and salinity in combination was more deleterious compared to alone treatments. Roots were more sensitive to all the stresses as compared to leaves. ICPH performed best among all the genotypes.

Published: June 2017

Forty nine genotypes of wheat were evaluated for 12 quantitative and one quality traits during 2010-11. The experiment was conducted in randomized complete block design with three replications at Crop Research Centre, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The mean, range, genotypic and phenotypic coefficient of variation, heritability in broad sense, genetic advance correlation and path analysis were analyzed. Plant height, number of productive tillers per plant, spike length, 1000-grain weight, biological yield per plant and harvest index were significant and positive correlated with grain yield per plant. The phenotypic and genotypic path coefficients exhibited high positive direct contribution of number of productive tillers per plant, plant height, harvest index and 1000-grain weight towards grain yield.The positive indirect effect of plant height on grain yield was registered via days to maturity, number of spikelets per spike, 1000-grain weight and biological yield per plant. Number of productive tillers per plant revealed contribution on grain yield via number of grains per spike, 1000 grain weight, biological yield per plant and harvest index revealing that indirect selection of these characters would be effective in improving grain yield per plant. Higher genotypic coefficient of variance along with high heritability and genetic advance for grain yield per plant, plant height, number of spikelets per spike, number of grains per spike and 1000-grain weight would also be of great use for indirect selection for improvement in yield per plant.

Grain yield response of drought stressed wheat to foliar application of glycine betaine
Authors: Gupta Neha , Thind Sanjeev Kaur
Published: June 2017

A field experiment was conducted to investigate influence of exogenous application of glycine betaine (GB) on performance of wheat under prolonged drought conditions. A set of 19 wheat genotypes differing in stress sensitivity, were sprayed with 100mM GB at maximum tillering and anthesis stage. GB treatment significantly declined the phenological pace under drought stress by increasing days to anthesis. Foliar applied GB improved grains/ spike and thousand grain weight of selected wheat genotypes over stressed ones. The genotype specific response to GB application suggested some threshold optimum level to be necessary for yield improvement under drought stress in susceptible genotypes as compared with tolerant ones. In overall, GB alleviated negative effects of drought stress by a rise in harvest index of most genotypes suggesting its role in assimilate translocation.

The production of roses in Ecuador is an economic opportunity that has been increasing since the 1980's. Ecuador is the fourth country in the world with a comparative advantage in rose production. Its quality and variety of colors has positioned the Ecuadorian rose as one of the best in the world. The research aims to compare four control treatments of the red spider (Tetranychus spp). Three of them are controlled through biological control (Verticillium Lecanii), while one of them is through chemical control. It tries to identify which one is the most efficient and that has the greatest economic benefit when compared to the control costs of each treatment. The results show significant evidence on T4 (chemical control), which is not only the most efficient in controlling mites at all stages of development. Also, it proves to be the least costly and it therefore provides greater profitability to the company.

Nuestro objetivo con este artículo es llamar la atención sobre la necesidad de impulsar este tipo de investigaciones en España y aportar algunos indicadores iniciales a partir del análisis de las mujeres al frente de sus hogares en la Castilla interior del Antiguo Régimen. En este sentido, abordaremos las características de sus unidades familiares, su estructura, tamaño y composición e, incluso, nos preguntaremos por cuántas mujeres corresidían sin la presencia de ningún varón. Para ello, compararemos los datos generales con los correspondientes a las jefaturas femeninas y éstos con el comportamiento de los hogares encabezados por mujeres viudas con 50 o más años. Un grupo de edad muy adecuado para estudiar la incidencia de la soledad al reducirse considerablemente las posibilidades de volver a contraer nupcias y perpetuar la inexistencia de la figura masculina de referencia.Palabras clave: Familia, hogares, mujeres, soledad, Castilla, Siglo XVIIIAbstract: We currently know little about solitude in the rural world. This paper aims to call the attention about the need to promote this type of research in Spain, and provide some initial indicators starting from the analysis of women as head of households in inland Castile during the Ancien Regime. In this regard, we adress the different characteristics of the households, their structure, size and composition. We also deep into the number of women that resided with no male relative. To that end, we compare general data with those that correspond to female head of households, and the former with the behavior of the widows aged 50 years or over households. This is a very appropriate age group to study the incidence of solitude, because the possibilities of getting married again are very low and they perpetuate that lack of a male figure reference in the household.Key words: Family, households, women, solitude, Castile, 18th Century
Zitelle e zitellacce. Prejudices and scorn in the perception of widows and single women in Italy in the 19th century
Authors: Miscali Monica
Published: June 2017

Abstract: Living alone in the pre-industrial world often created more complications for women than for men. The main source of this discrimination was a widespread prejudicial and hostile attitude towards unattached women and widows in general. Past societies have generated both pejorative and celebratory words to describe women who have never been married or were widowed. Expressions such as “old maid”, “vecchia zitella” or the slightly more benevolent expression “poor widow” have become commonplace. The aim of this paper is firstly to highlight the negative prejudices suffered by single women and widows in past centuries. Secondly, it hopes to demonstrate the considerable change in society’s attitude towards unmarried women that accompanied the rise of the bourgeois society and that transformed the semantic sense of the otherwise neutral word zitella to the pejorative one it has today. Despite focusing on the particular case of Italy, it will also seek to give a brief overview of the situation in the rest of Europe.Key words: Widows, single women, zitella, prejudices, stereotypes, ItalyRésumé: Vivre seul dans le monde préindustriel a souvent créé plus de complications pour les femmes que pour les hommes. La principale source de cette discrimination était une attitude préjudiciable et hostile envers les femmes seules et les veuves en général. Les sociétés du passé ont généré de nombreux mots péjoratifs pour décrire les femmes qui n’ont jamais été mariées ou qui étaient veuves. Combien de fois avons-nous entendu des mots tels que «old maid», ou bien «vieille fille» ou encore l’expression apparemment bienveillante “pauvre veuve”. Le but de cet article est de mettre en évidence les préjugés négatifs qui ont été employé au cours des siècles passésafin de décrire les femmes célibataires et les veuves et de montrer comment l’attitude de la société envers les femmes célibataires a considérablement changé avec la montée de la société bourgeoise qui a transformé le sens sémantique du mot “zitella” originairement neutre en un terme au sens aujourd’hui péjoratifact francese. L’article se concentrera sur les cas de l’Italie, mais il cherchera aussi à donner un bref aperçu de la situation dans le reste de l’Europe.Mots-clés: Veuves, femmes célibataires, vieille fille, préjugés, stéréotypes, zitella
La Antigüedad, ¿virtuosa o esclavista? Un debate de la Ilustración
Authors: Montoya Rubio Bernat
Published: June 2017

Resumen: La concepción que actualmente tenemos de la Antigüedad greco-romana, como un período con unas características socio-económicas particulares claramente diferenciadas de la Europa moderna, no se deriva únicamente de los datos aportados por las fuentes y de las investigaciones históricas del siglo XIX. Esta interpretación de la Antigüedad se configura durante la segunda mitad del s. XVIII en estrecha relación con los debates sobre la situación política y económica que caracterizan este período. El objetivo de este artículo es mostrar cómo la dinámica de estos debates afecta a los cambios en la forma de entender la Antigüedad clásica.Palabras clave: Concepción de la Antigüedad, esclavitud antigua, paradigma del humanismo cívico, Pocock, Montesquieu, Adam Smith, Rousseau, MablyAbstract: The current understanding of classical Antiquity, i.e., a period with a number of socio-economical characteristics clearly differentiated from those of Modern Europe, is not solely derived from data provided by Classical texts and the historical research of the 19th century. This interpretation of Antiquity, which appeared during the latter half of the 18th century, bears a close connection to discussions on the political and economic state that characterise the period. The aim of this article is to show the impact of the dynamics of these debates on the changes in the way Classical Antiquity is understood.Key words: Perception of Antiquity, ancient slavery, civic humanist paradigm, Pocock, Montesquieu, Adam Smith, Rousseau, Mably
Aproximación al estudio de las antigüedades en la América española en el siglo XVIII a través de tres instrucciones
Authors: León Gómez Alicia , Gil Fernández Raquel
Published: June 2017

Resumen: En este artículo analizamos tres instrucciones emitidas en el siglo XVIII en las que se alude al tratamiento de vestigios arqueológicos de la América española. A través de ellas podemos observar la evolución en la concepción imperante en cada momento sobre los restos arqueológicos, y cómo se va trascendiendo desde la perspectiva anticuarista hasta una nueva corriente en la que se empiezan a tratar como fuente de información. Centrándonos en los capítulos dedicados a antigüedades, analizaremos el cuerpo de las instrucciones redactadas por Franco Dávila, Antonio de Ulloa y José de Estacharía y el tratamiento que se recomienda en las mismas para los restos muebles e inmuebles hallados en la América Colonial.Palabras clave: Instrucciones, Historia de la arqueología de la América Colonial, anticuarismo, novatores, antigüedades americanasAbstract: In this article, we analyse three sets of instructions, issued in the 18th century, referring to the treatment of the archaeological vestiges of Spanish America. Through them we can trace the evolution of the prevailing idea concerning archaeological remains at every moment, and how a shift from the antiquarian perspective to a new trend will allow them to be treated as a source of information. We analyse the body of instructions written by Franco Davila, Antonio de Ulloa and José de Estacharía, focusing on the chapters dedicated to antiques, which recommended treatment for the remains and personal property found in Colonial America.Key words: Instructions, History of the American Colonial archaeology, antiquarianism, novatores, American antiques

Completando seu 11o volume, a Revista Brasileira de Inovação apresenta neste número uma reedição do artigo clássico de Gerald Silverberg, Giovanni Dosi e Luigi Orsenigo: Innovation, Diversity and Diffusion: A Self-Organisation Model, originalmente publicado em 1988 no periódico The Economic Journal. Ao apresentar o artigo, Gabriel Porcile destaca que o modelo teórico construído pelos autores fundamenta-se na abordagem pioneira de Richard Nelson e Sidney Winter sobre a dinâmica coevolutiva da inovação e da difusão tecnológica. Aponta ainda os principais pontos que dão sustentação ao modelo, faz excelente contraponto com o modelo convencional da firma representativa, e discute sucintamente visões complementares e desdobramentos teórico-metodológicos a partir da contribuição de Silverberg, Dosi e Orsenigo.
