El objetivo de este estudio es contribuir al entendimiento, desde un punto de vista histórico, del papel que juega el cine en los procesos de popularización de la ciencia, la medicina y la tecnología. El punto de partida es la consideración de la medicina y del cine como conjuntos complejos y multidimensionales de “prácticas y discursos” de carácter científico-tecnológico y, por tanto, como formas particulares de acción e interacción cotidiana entre personas, colectivos e instituciones que juegan un papel básico en los procesos de construcción y funcionamiento de las sociedades contemporáneas. Así, mediante el análisis de la representación y articulación de las prácticas y los discursos médico-sanitarios en el cine documental colonial español del primer franquismo, es decir, en el caso particular de la construcción, legitimación y consolidación de un régimen totalitario, se aportan algunas claves explicativas sobre las múltiples relaciones entre diferentes colectivos (expertos y no-expertos) en cuanto a la naturaleza y el nivel de intervención en los procesos de generación y gestión de conocimiento científico-tecnológico. Como resultado, el cine se revela como un espacio no sólo de evasión y entretenimiento, sino también de ciencia y educación, donde la capacidad de definir y solucionar problemas cotidianos de la población, y por tanto, su impacto en la construcción de la arquitectura social, ideológica, económica, política y cultural de las sociedades contemporáneas, se fundamenta en la combinación de sus aspectos como espectáculo narrativo y científico-tecnológico.

Uranium mines are the - often forgotten - source of nuclear power. The promotion of nuclear energy as a clean alternative and the projected increase of electricity demand in countries such as China and India, have led to a global “uranium rush”, unseen since the peak of the Cold War. This article studies the formation of the expanding nuclear frontier looking at the interaction between the global uranium metabolism, industrial dynamics and local ecologies of resistance using Namibia as a case-study. Namibia, the world´s fourth largest producer of uranium, stands at the frontier of this rush with sixty-six recently granted prospecting licenses that could turn into mines, compared to only three currently operating mines. We focus on three generic attributes that help to explain the emergence and intensity of resistance by local communities to uranium mining: the ecology and geography of the resource; the degree and type of political and economic marginalization of the community; and crucially, the connection and integration of local concerns with broader social movements and political demands. We show with the use of empirical material how these factors play out differently in five Namibian communities that have been, or stand to be, affected by uranium mining, and explain how local ecologies of resistance shape the global uranium rush.

This paper analyses whether a firm’s absorptive capacity and its distance from the technological frontier affect the choice between innovation and imitation in innovative Spanish firms. From an extensive survey of 5,575 firms during the 2004-2009 period, we found two significant results. With regard to the role of absorptive capacity, the empirical evidence shows that when innovative firms have difficulties in accessing external information and hire skilled workers, their innovative capacity is reduced. Meanwhile, with regard to distance from the technological frontier, the firms that reduce this gap manage to increase their innovative capacity at the expense of imitation. To summarise, when we studied firms’ absorptive capacity and their relative position to the technological frontier in tandem, we found that the two factors directly affected firms' ability to innovate or imitate.

This paper explores how absorptive capacity affects the innovative performance and productivity dynamics of Spanish firms. A firm’s efficiency levels are measured using two variables: the labour productivity and the Total Factor Productivity (TFP). The theoretical framework is based on the seminal contributions of Cohen and Levinthal (1989, 1990) regarding absorptive capacity; and the applied framework is based on the four-stage structural model proposed by Crépon, Duguet and Mairesse (1998) for setting the determinants of R&D, the effects of R&D activities on innovation outputs, and the impacts of innovation on firm productivity. The present study uses a twostage structural model. In the first stage, a probit estimation is used to investigate how the sources of R&D, the absorptive capacity and a vector of the firm’s individual features influence the firm’s likelihood of developing innovations in products or processes. In the second phase, a quantile regression is used to analyze the effect of R&D sources, absorptive capacity and firm characteristics on productivity. This method shows the elasticity of each exogenous variable on productivity according to the firms’ levels of efficiency, and thus allows us to distinguish between firms that are close to the technological frontier and those that are further away from it. We used extensive firm-level panel data from 5,575 firms for the 2004-2009 period. The results show that the internal absorptive capacity has a strong impact on the productivity of firms, whereas the role of external absorptive capacity differs according to nature of the each industry and according the distance of firms from the technological frontier. Key words: R&D sources, innovation strategies, absorptive capacity, technological distance, quantile regression.

The Asian Diaspora in the Americas in the 16th and 17th has been neglected by scholars for a long time. This fact is baffling, not only for the great interest of this topic in of itself, but also because it could provide new knowledge of colonial Mexico, especially in terms of the interaction among the many groups that populated the colony. This early movement of people and ideas across the largest extension of water in the planet is characteristic of what has been called the ¿archaic globalization,¿ and thus research on these matters could contribute to the history of globalization.In this presentation, I seek to further elaborate on the themes outlined by Edward Slack in The Chinos in New Spain: A Corrective Lens for a Distorted Image, an article published in 2009 in the Journal of World History. Firstly, I would like to bring forth some evidence that indicates that Asian religious practices were present in Mexico in the 1600s. Furthermore, I will argue that the traces of these practices are still visible today, in the form of a popular fortune-telling tradition. Secondly, I intend to provide some information about the arrival, settlement and distribution of the Asian Diaspora. I will focus on their distribution within Mexico City. Thirdly, I will elaborate on their occupations, social status and daily life, as well as in the patterns in marriages and relations with other groups. And lastly, I will show how the guild of barbers served as an Asian immigrant reception network.

El projecte de recerca ha analitzat la complexitat ètnica, social i de gènere de l’assentament colonial d’Empúries a partir d’un exhaustiu estudi contextual dels materials ceràmics d’ús quotidià provinents de diferents sectors excavats als anys vuitanta a la Neàpolis empuritana (N-7000, N-5000 i N-1000). Aquests sectors datats els segles V i IV a.C., corresponen a un moment en el qual s’està construint una identitat colonial diferenciada en l’espai emporità. La comparació dels aixovars domèstics usats quotidianament pels habitants d’aquest tres sectors situats en punts distants de la Neàpolis mostra que estem davant d’un assentament colonial molt heterogeni, on conflueixen materialitats, tradicions tecnològiques i pràctiques quotidianes iberes, gregues i híbrides. Els estudis de materials confirmen que no va existir una segregació espacial entre poblacions d’origen grec i iber en aquest assentament i suggereixen la cohabitació de gent –tant d’homes com de dones- d’origen grec i iber a les diferents àrees estudiades d’aquest assentament portuari. En el registre material ceràmic de totes les zones estudiades s’observa un predomini dels productes ceràmics de tradició grega (colonials o àtics) en els serveis de taula, però no així en els estris utilitzats a la cuina, que són majoritàriament de tradició ibera. També els materials ceràmics relacionats amb l’emmagatzematge domèstic i amb el transport i el comerç (àmfores) són predominantment ibers. Aquest patró suggereix que els ibers que van cohabitar amb els grecs al port emporità no van assumir en tots els casos posicions subalternes, sinó que tingueren un rol rellevant en la gestió econòmica i comercial d’aquest espai portuari.

The view of a 1870-1913 expanding European economy providing increasing welfare to everybody has been challenged by many, then and now. We focus on the amazing growth that was experienced, its diffusion and its sources, in the context of the permanent competition among European nation states. During 1870-193 the globalized European economy reached a silver age . GDP growth was quite rapid (2.15% per annum) and diffused all over Europe. Even discounting the high rates of population growth (1.06%), per capita growth was left at a respectable 1.08%. Income per capita was rising in every country, and the rates of improvement were quite similar. This was a major achievement after two generations of highly localized growth, both geographically and socially. Growth was based on the increased use of labour and capital, but a good part of growth (73 per cent for the weighted average of the best documented European countries) came out of total factor productivity efficiency gains resulting from not well specified ultimate sources of growth. This proportion suggests that the European economy was growing at full capacity at its production frontier. It would have been very difficult to improve its performance. Within Europe, convergence was limited, and it only was in motion after 1900. What happened was more the end of the era of big divergence rather than an era of convergence.

This paper estimates a translog stochastic frontier production function in the analysis of all 48 contiguous U.S. states in the period 1970-1983, to attempt to measure and explain changes in technical efficiency. The model allows technical inefficiency to vary over time, and inefficiency effects to be a function of a set of explanatory variables in which the level and composition of public capital plays an important role. Results indicated that U.S. state inefficiency levels were significantly and positively correlated with the ratio of public capital to private capital. The proportion of public capital devoted to highways is negatively correlated with technical inefficiency, suggesting that not only the level but also the composition of public capital influenced state efficiency.

The principal aim of this paper is to estimate a stochastic frontier costfunction and an inefficiency effects model in the analysis of the primaryhealth care services purchased by the public authority and supplied by 180providers in 1996 in Catalonia. The evidence from our sample does not supportthe premise that contracting out has helped improve purchasing costefficiency in primary care. Inefficient purchasing cost was observed in thecomponent of this purchasing cost explicitly included in the contract betweenpurchaser and provider. There are no observable incentives for thecontracted-out primary health care teams to minimise prescription costs, whichare not explicitly included in the present contracting system.

The dominant hypothesis in the literature that studies conflict is that poverty is the main cause of civil wars. We instead analyze the effect of institutions on civil war, controlling for income per capita. In our set up, institutions are endogenous and colonial origins affect civil wars through their legacy on institutions. Our results indicate that institutions, proxied by the protection of property rights, rule of law and the efficiency of the legal system, are a fundamental cause of civil war. In particular, an improvement in institutions from the median value in the sample to the 75th percentile is associated with a 38 percentage points reduction in the incidence of civil wars. Moreover, once institutions are included as explaining civil wars, income does not have any effect on civil war, either directly or indirectly.

When did overseas trade start to matter for living standards? Traditional real-wage indices suggest that living standards in Europe stagnated before 1800. In this paper, we argue thatwelfare rose substantially, but surreptitiously, because of an influx of new goods as a result ofoverseas trade. Colonial luxuries such as tea, coffee, and sugar transformed European diets afterthe discovery of America and the rounding of the Cape of Good Hope. These goods became household items in many countries by the end of the 18th century. We use three different methodsto calculate welfare gains based on price data and the rate of adoption of these new colonialgoods. Our results suggest that by 1800, the average Englishman would have been willing to forego 10% or more of his income in order to maintain access to sugar and tea alone. These findings are robust to a wide range of alternative assumptions, data series, and valuation methods.

L'anàlisi del festeig com activitat social en les societats prehistòriques i protohistòriques, així com el seu paper en les relacions de poder, ha estat un dels temes recurrents en la literatura arqueològica generada en els darrers vint anys i referent a zones i períodes extremadament diversos. A la Mediterrània occidental i l"Europa central han estat particularment influents els treballs de M. Dietler, autor que, a partir d"un important volum de documentació etnogràfica, va proposar una tipologia de banquets en contextos socials de diferents naturaleses que és susceptible d"explicar aspectes rellevants de la documentació arqueològica coneguda de la Protohistòria a la costa mediterrània de la Península Ibèrica i la Gàl·lia entre altres, el volum i naturalesa canviants dels materials d"importació , tal com s"ha mostrat en diversos treballs més o menys recents (Dietler, 1990, 1996, 1999). Per als autors d"aquest treball, les idees elaborades per Dietler continuen essent plenament vàlides i conserven tot el seu potencial heurístic i explicatiu, per la qual cosa val la pena recordar-les breument.
