En busca de tinterillos. Intermediarios en el mundo indígena ecuatoriano durante el siglo XX (Debates)

Este artículo aborda el papel de los abogados semiprofesionales, conocidos como tinterillos, en las comunidades indígenas de la sierra ecuatoriana, a partir de mediados del siglo XIX, quienes adquirieron una presencia aparentemente ubicua en las comunidades rurales del Ecuador. Muchas veces los tinterillos fueron parte de las élites locales con algo de educación. Inspiraban respeto entre los indígenas (quienes, en su mayoría, eran analfabetos) debido a su habilidad a manejar documentos escritos. Estos intermediarios comúnmente explotaron su posición privilegiada para su propio beneficio económico, social y político. Sin embargo, los indígenas llegaron a depender del apoyo de los tinterillos para denunciar ante el gobierno los abusos de los terratenientes. En ocasiones, en lugar de sentirse impotentes o víctimas, los indígenas aprendieron a negociar sus relaciones con esos intermediarios para su beneficio. El estudio de los tinterillos permite examinar las relaciones de poder que se negociaron entre diferentes culturas y a través de profundas divisiones de clase.

La responsabilidad social del periodismo: procesos informativos, debates políticos y ejes de políticas públicas en el contexto de la Ley de Comunicación en el Ecuador

Este trabajo analiza la confrontación entre el poder político y los medios privados en el contexto del debate de la Ley de Comunicación y reflexiona sobre las complejas relaciones entre comunicación cultura y política en la sociedad contemporánea. A la vez, realiza una reseña crítica de algunas prácticas informativas marcadas por la violencia simbólica - espectacularización, revictimización e indefensión- en evidente conflicto con la responsabilidad social. Plantea también las bases conceptuales de la responsabilidad social del periodismo y propone los ejes de trabajo de unas políticas públicas para mejorar las prácticas informativas: formación de periodistas; información con enfoque de derechos; nuevas agendas informativas; formación de audiencias críticas; visibilidad y participación social, y otras maneras de incidir en el campo mediático.

Museos de historia y producción de conocimientos: cuestiones para el debate (Debates)

The article thinks over the role of museums in the construction of scientific and historical representations and as a space that connects the forms of visualizing the past and the construction of historic knowledge. Also analyzes the museum as a setting of tension between the visualization and the generation of scientific or historical knowledge; and between the forms of evoking-representing and the sensitive cognitive processes that it activates in museum audiences. This oscillation takes place in the Museo Paulista.

La emergencia del intelectual en América Latina y el espacio público: el caso de Alfonso Reyes, 1927-1939 (Debates)

This article is a case study of the emergence of the intellectual in Spanish American: the trajectory of Alfonso Reyes. In Latin America modernity and the beginnings of the 20th Century contributed to circumstances and historical processes that permitted the 19th Century literates to progressively transform into intellectual: to be exact a ‘transitional intellectual’. This study looks at some of the dynamics that validated the intellectual as a new social actor during the period studied. The public visibility as it was never before, placed thinkers, and the use of means of communication of the time and the cultural elements like books and magazines, allowing that they be turned into public figures and to obtain some of their objectives.

Solar induced climate effects

Solar electromagnetic radiation powers Earth’s climate system and, consequently, it is often naively assumed that changes in this solar output must be responsible for changes in Earth’s climate. However, the Sun is close to a blackbody radiator and so emits according to its surface temperature and the huge thermal time constant of the outer part of the Sun limits the variability in surface temperature and hence output. As a result, on all timescales of interest, changes in total power output are limited to small changes in effective surface temperature (associated with magnetic fields) and potential, although as yet undetected, solar radius variations. Larger variations are seen in the UV part of the spectrum which is emitted from the lower solar atmosphere (the chromosphere) and which influences Earth’s stratosphere. There is interest in“top-down” mechanisms whereby solar UV irradiance modulates stratospheric temperatures and winds which, in turn, may influence the underlying troposphere where Earth’s climate and weather reside. This contrasts with “bottom-up” effects in which the small total solar irradiance (dominated by the visible and near-IR) variations cause surface temperature changes which drive atmospheric circulations. In addition to these electromagnetic outputs, the Sun modulates energetic particle fluxes incident on the Earth. Solar Energetic Particles (SEP) are emitted by solar flares and from the shock fronts ahead of supersonic (and super-Alfvenic) ejections of material from the solar atmosphere. These SEPs enhance the destruction of polar stratospheric ozone which could be an additional form of top-down climate forcing. Even more energetic are Galactic Cosmic Rays (GCRs). These particles are not generated by the Sun, rather they originate at the shock fronts emanating from violent galactic events such as supernovae explosions; however, the expansion of the solar magnetic field into interplanetary space means that the Sun modulates the number of GCRs reaching Earth. These play a key role in enabling Earth’s global electric (thunderstorm) circuit and it has been proposed that they also modulate the formation of clouds. Both electromagnetic and corpuscular solar effects are known to vary over the solar magnetic cycle which is typically between 10 and 14 yrs in length (with an average close to 11 yrs). The solar magnetic field polarity at any one phase of one of these activity cycles is opposite to that at the same phase of the next cycle and this influences some phenomena, for example GCRs, which therefore show a 22 yr (“Hale”) cycle on average. Other phenomena, such as irradiance modulation, do not depend on the polarity of the magnetic field and so show only the basic 11-yr activity cycle. However, any effects on climate are much more significant for solar drifts over centennial timescales. This chapter discusses and evaluates potential effects on Earth’s climate system of variations in these solar inputs. Because of the great variety of proposed mechanisms, the wide range of timescales studied (from days to millennia) and the many debates (often triggered by the application of inadequate statistical methods), the literature on this subject is vast, complex, divergent and rapidly changing: consequently the number of references cited in this review is very large (yet still only a small fraction of the total).

Review: intellectual property aspects of plant transformation

One of the recurring themes of the debates concerning the application of genetic transformation technology has been the role of Intellectual Property Rights (IPR). This term covers both the content of patents and the confidential expertise usually related to methodology and referred to as 'Trade Secrets'. This review explains the concepts behind patent protection, and discusses the wide-ranging scope of existing patents that cover all aspects of transgenic technology, from selectable markers and novel promoters to methods of gene introduction. Although few of the patents in this area have any real commercial value, there are a small number of key patents that restrict the 'freedom to operate' of new companies seeking to exploit the methods. Over the last 20 years, these restrictions have forced extensive cross-licensing between ag-biotech companies and have been one of the driving forces behind the consolidation of these companies. Although such issues are often considered of little interest to the academic scientist working in the public sector, they are of great importance in any discussion of the role of 'public-good breeding' and of the relationship between the public and private sectors.

‘Trying to be a Man': J. M. Barrie and sentimental masculinity

This article discusses the treatment of sentimentality in the fiction of J.M. Barrie, focusing in particular on Tommy and Grizel (1900). It place the discussion in the context of wider debates over sentimentality in Victorian culture and explores the intersection between these and discourse of gender and sexuality in the late nineteenth century.

The hanging man: death, indeterminacy and the event

This article discusses approaches to the interpretation and analysis an event that is poised between reality and performance. It focuses upon a real event witnessed by the author while driving out of Los Angeles, USA. A body hanging on a rope from a bridge some 25/30 feet above the freeway held up the traffic. The status of the body was unclear. Was it the corpse of a dead human being or a stuffed dummy, a simulation of a death? Was it is tragic accident or suicide or was it a stunt, a protest or a performance? Whether a real body or not, it was an event: it drew an audience, it took place in a defined public space bound by time and it disrupted everyday normality and the familiar. The article debates how approaches to performance can engage with a shocking event, such as the Hanging Man, and the frameworks of interpretation that can be brought to bear on it. The analysis takes account of the function of memory in reconstructing the event, and the paradigms of cultural knowledge that offered themselves as parallels, comparators or distinctions against which the experience could be measured, such as the incidents of self-immolation related to demonstrations against the Vietnam War, the protest by the Irish Hunger Strikers and the visual impact of Anthony Gormley’s 2007 work, 'Event Horizon'. Theoretical frameworks deriving from analytical approaches to performance, media representation and ethical dilemmas are evaluated as means to assimilate an indeterminate and challenging event, and the notion of what an ‘event’ may be is itself addressed.

Are the debates on water privatization missing the point? Experiences from Africa, Asia and Latin America

This paper has two principal aims: first, to unravel some of the arguments mobilized in the controversial privatization debate, and second, to review the scale and nature of private sector provision of water and sanitation in Africa, Asia and Latin America. Despite being vigorously promoted in the policy arena and having been implemented in several countries in the South in the 1990s, privatization has achieved neither the scale nor benefits anticipated. In particular, the paper is pessimistic about the role that privatization can play in achieving the Millennium Development Goals of halving the number of people without access to water and sanitation by 2015. This is not because of some inherent contradiction between private profits and the public good, but because neither publicly nor privately operated utilities are well suited to serving the majority of low-income households with inadequate water and sanitation, and because many of the barriers to service provision in poor settlements can persist whether water and sanitation utilities are publicly or privately operated. This is not to say that well-governed localities should not choose to involve private companies in water and sanitation provision, but it does imply that there is no justification for international agencies and agreements to actively promote greater private sector participation on the grounds that it can significantly reduce deficiencies in water and sanitation services in the South.

(PDF, 406 KB) On L3 acquisition and phonological permeability: a new test case for debates on the mental representation of non-native phonological systems

The goal of this article is to make an epistemological and theoretical contribution to the nascent field of third language (L3) acquisition and show how examining L3 development can offer a unique view into longstanding debates within L2 acquisition theory. We offer the Phonological Permeability Hypothesis (PPH), which maintains that examining the development of an L3/Ln phonological system and its effects on a previously acquired L2 phonological system can inform contemporary debates regarding the mental constitution of postcritical period adult phonological acquisition. We discuss the predictions and functional significance of the PPH for adult SLA and multilingualism studies, detailing a methodology that examines the effects of acquiring Brazilian Portuguese on the Spanish phonological systems learned before and after the so-called critical period (i.e., comparing simultaneous versus successive adult English-Spanish bilinguals learning Brazilian Portuguese as an L3).

On the (un)-ambiguity of adjectival modification in Spanish determiner phrases: informing debates on the mental representations of L2 syntax.

This study contributes to a central debate within contemporary generative second language (L2) theorizing: the extent to which adult learners are (un)able to acquire new functional features that result in a L2 grammar that is mentally structured like the native target (see White, 2003). The adult acquisition of L2 nominal phi-features is explored, with focus on the syntactic and semantic reflexes in the related domain of adjective placement in two experimental groups: English-speaking intermediate (n = 21) and advanced (n = 24) learners of Spanish, as compared to a native-speaker control group (n = 15). Results show that, on some of the tasks, the intermediate L2 learners appear to have acquired the syntactic properties of the Spanish determiner phrase but, on other tasks, to show some delay with the semantic reflexes of prenominal and postnominal adjectives. Crucially, however, our data demonstrate full convergence by all advanced learners and thus provide evidence in contra the predictions of representational deficit accounts (e.g., Hawkins & Chan, 1997; Hawkins & Franceschina, 2004; Hawkins & Hattori, 2006).
