Análisis del proceso que condujo a la construcción del concepto de explotación inserto en el Protocolo para prevenir, reprimir y sancionar la trata de personas, incorporado a la legislación colombiana a través de la Ley 800 de 2003

El objetivo de este trabajo de grado es describir una disputa política por el significado del concepto de explotación en el marco de la redacción del “Protocolo para prevenir, reprimir y sancionar la trata de personas, especialmente mujeres y niños”, en el cual se define aquello que se entiende por trata de personas. La construcción de este concepto excluye e invisibiliza otros tipos de explotación comunes en el sistema de producción capitalista contemporánea que pertenecen al universo de violencia objetiva sistémica a través del énfasis en la explotación sexual que hace parte de la violencia subjetiva.

Análisis de los programas de la agencia española de cooperación internacional para el desarrollo dirigidos a las mujeres en la lucha contra el vih/sida en mozambique (2005-2010)

En este estudio de caso pretende dar respuesta a que factores vitalizan la cooperación Española en Mozambique a través del análisis de programas como el VITA, dirigidos específicamente al desarrollo y mejoramiento de la salud en el continente Africano. Este estudio de caso se centra en el investigación de los discursos de desarrollo que se fundamentan en las políticas internacionales de cooperación , basadas en la existencia de una enfermedad como el VIH que ha puesto en manifiesto la interacción entre la esfera biológica y social , social e individual entre el fenómeno existencial y cultural, lo que fundamenta su importancia y estudio. Se ha escogido esta herramienta de investigación social, en este estudio de caso, para abordar la forma en que funciona y opera la AECID en Mozambique a través de los programas con enfoque de género encaminados al problema del VIH. Se pretende dar a conocer el desarrollo en materia de la cooperación internacional de una organización tan importante como la AECID, cuyos proyectos gozan de una gran credibilidad en cuanto a la ejecución de sus acciones y que en general dichos proyectos se adecuan a las necesidades de la población, a los objetivos de desarrollo nacionales y a las prioridades de la cooperación española.

Transformaciones discursivas en el proceso de securitización del narcotráfico. Un análisis de los actos discursivos oficiales de Colombia y Estados Unidos en la Guerra contra las drogas 1986 - 1990

El tema de las drogas suscita un debate entre quienes defienden la prohibición y la represión, y aquellos que defienden alternativas como la legalización y/o regulación y otras más moderadas como la descriminalización y la despenalización. Aunque ambas posturas muestran datos empíricos que las soportan, desde el ámbito discursivo la visión represiva se ha posicionado como la más aceptada en el continente americano, más específicamente, en Latinoamérica. El presente trabajo, hace un estudio de caso del proceso de securitización del narcotráfico entre los presidentes de Estados Unidos y Colombia durante el período 1986-1990. A lo largo del texto, se analizan discursos oficiales de los presidentes de ambos Estados, resaltando las estrategias retóricas y sus transformaciones que legitimaron acciones represivas de tipo político-militar contra las drogas. Al final se apunta a reivindicar el discurso como un instrumento para reproducir creencias sobre fenómenos, en este caso, la creencia de que las drogas son una amenaza existencial a la seguridad política y militar para los Estados.

The importance of the relationship between scale and process in understanding long-term DOC dynamics

Concentrations of dissolved organic carbon have increased in many, but not all, surface waters across acid impacted areas of Europe and North America over the last two decades. Over the last eight years several hypotheses have been put forward to explain these increases, but none are yet accepted universally. Research in this area appears to have reached a stalemate between those favouring declining atmospheric deposition, climate change or land management as the key driver of long-term DOC trends. While it is clear that many of these factors influence DOC dynamics in soil and stream waters, their effect varies over different temporal and spatial scales. We argue that regional differences in acid deposition loading may account for the apparent discrepancies between studies. DOC has shown strong monotonic increases in areas which have experienced strong downward trends in pollutant sulphur and/or seasalt deposition. Elsewhere climatic factors, that strongly influence seasonality, have also dominated inter-annual variability, and here long-term monotonic DOC trends are often difficult to detect. Furthermore, in areas receiving similar acid loadings, different catchment characteristics could have affected the site specific sensitivity to changes in acidity and therefore the magnitude of DOC release in response to changes in sulphur deposition. We suggest that confusion over these temporal and spatial scales of investigation has contributed unnecessarily to the disagreement over the main regional driver(s) of DOC trends, and that the data behind the majority of these studies is more compatible than is often conveyed.

Link between DOC in near surface peat and stream water in an upland catchment

Hydrologic transport of dissolved organic carbon (DOC) from peat soils may differ to organo-mineral soils in how they responded to changes in flow, because of differences in soil profile and hydrology. In well-drained organo-mineral soils, low flow is through the lower mineral layer where DOC is absorbed and high flow is through the upper organic layer where DOC is produced. DOC concentrations in streams draining organo-mineral soils typically increase with flow. In saturated peat soils, both high and low flows are through an organic layer where DOC is produced. Therefore, DOC in stream water draining peat may not increase in response to changes in flow as there is no switch in flow path between a mineral and organic layer. To verify this, we conducted a high-resolution monitoring study of soil and stream water at an upland peat catchment in northern England. Our data showed a strong positive correlation between DOC concentrations at − 1 and − 5 cm depth and stream water, and weaker correlations between concentrations at − 20 to − 50 cm depth and stream water. Although near surface organic material appears to be the key source of stream water DOC in both peat and organo-mineral soils, we observed a negative correlation between stream flow and DOC concentrations instead of a positive correlation as DOC released from organic layers during low and high flow was diluted by rainfall. The differences in DOC transport processes between peat and organo-mineral soils have different implications for our understanding of long-term changes in DOC exports. While increased rainfall may cause an increase in DOC flux from peat due to an increase in water volume, it may cause a decrease in concentrations. This response is contrary to expected changes in DOC exports from organo-mineral soils, where increase rainfall is likely to result in an increase in flux and concentration.

Variation in the sensitivity of DOC release between different organic soils following H2SO4 and sea-salt additions

Long-term monitoring data from eastern North America and Europe indicate a link between increased dissolved organic carbon (DOC) concentrations in surface waters over the last two decades and decreased atmospheric pollutant and marine sulphur (S) deposition. The hypothesis is that decreased acidity and ionic strength associated with declining S deposition has increased the solubility of DOC. However, the sign and magnitude of DOC trends have varied between sites, and in some cases at sites where S deposition has declined, no significant increase in DOC has been observed, creating uncertainty about the causal mechanisms driving the observed trends. In this paper, we demonstrate chemical regulation of DOC release from organic soils in batch experiments caused by changes in acidity and conductivity (measured as a proxy for ionic strength) associated with controlled SO42− additions. DOC release from the top 10 cm of the O-horizon of organo-mineral soils and peats decreased by 21–60% in response to additions of 0–437 µeq SO42− l−1 sulphuric acid (H2SO4) and neutral sea-salt solutions (containing Na+, Mg2+, Cl−, SO42−) over a 20-hour extraction period. A significant decrease in the proportion of the acid-sensitive coloured aromatic humic acids (measured by specific ultra-violet absorbance (SUVA) at 254 nm) was also found with increasing acidity (P < 0.05) in most, but not all, soils, confirming that DOC quality, as well as quantity, changed with SO42− additions. DOC release appeared to be more sensitive to increased acidity than to increased conductivity. By comparing the change in DOC release with bulk soil properties, we found that DOC release from the O-horizon of organo-mineral soils and semi-confined peats, which contained greater exchangeable aluminium (Al) and had lower base saturation (BS), were more sensitive to SO42− additions than DOC release from blanket peats with low concentrations of exchangeable Al and greater BS. Therefore, variation in soil type and acid/base status between sites may partly explain the difference in the magnitude of DOC changes seen at different sites where declines in S deposition have been similar.

Prizes for modernity in the provinces: The Arts Council’s 1950-1951 regional playwriting competition

As part of its contribution to the 1951 Festival of Britain, the Arts Council ran what can be seen in retrospect to be an important playwriting competition. Disregarding the London stage entirely, it invited regional theatres throughout the UK to put forward nominations for new plays within their repertoire for 1950-1951. Each of the five winning plays would receive, what was then, the substantial sum of £100. Originality and innovation featured highly amongst the selection criteria, with 40 per cent of the judges’ marks being awarded for “interest of subject matter and inventiveness of treatment”. This article will assess some of the surprising outcomes of the competition and argue that it served as an important nexus point in British theatrical historiography between two key moments in post-war Britain: the first being the inauguration of the Festival of Britain in 1951, the other being the debut of John Osborne’s Look Back in Anger in May 1956. The article will also argue that the Arts Council’s play competition was significant for two other reasons. By circumventing the London stage, it provides a useful tool by which to reassess the state of new writing in regional theatre at the beginning of the 1950s and to question how far received views of parochialism and conservatism held true. The paper will also put forward a case for the competition significantly anticipating the work of George Devine at the English Stage Company, which during its early years established a reputation for itself by heavily exploiting the repertoire of new plays originally commissioned by regional theatres. This article forms part of a five year funded Arts and Humanities Research Council (AHRC) project, ‘Giving Voice to the Nation: The Arts Council of Great Britain and the Development of Theatre and Performance in Britain 1945-1994’.

The seaweed flora of Admiralty Bay, King George Island, Antarctic

Admiralty Bay is located on the western side of King George Island. Although several research teams of different nationalities have carried out surveys in the region for decades, there are only two publications dealing with the seaweed flora of the bay. Here, we report on a taxonomic survey of the seaweeds we collected during the 25th Brazilian Antarctic Expedition (December 2006/November 2007). We discovered 42 species (21 Rhodophyta, 14 Phaeophyceae, and 7 Chlorophyta), corresponding to an increase of about 31% in the seaweed biodiversity hitherto known for the region. Considering that the Antarctic Peninsula, adjacent to King George Island seems to be one of the most rapidly warming spots on the planet, this kind of survey may provide a valuable tool for detecting eventual changes in seaweed biodiversity.

Apoptosis may underlie the pathology of zinc-deficient skin

The trace element zinc is essential for the survival and function of all cells. Zinc deficiency, whether nutritional or genetic, is fatal if left untreated. The effects of zinc deficiency are particularly obvious in the skin, seen as an erythematous rash, scaly plaques, and ulcers. Electron microscopy reveals degenerative changes within keratinocytes. Despite the well-documented association between zinc deficiency and skin pathology, it is not clear which cellular processes are most sensitive to zinc deficiency and could account for the typical pathological features. We used the cultured HaCaT keratinocyte line to obtain insight into the cellular effects of zinc deficiency, as these cells show many characteristics of normal skin keratinocytes. Zinc deficiency was induced by growing cells in the presence of the zinc chelator, TPEN, or by growth in zinc-deficient medium. Growth of cells in zinc-deficient medium resulted in a 44% reduction of intracellular zinc levels and a 75% reduction in the activity of the zinc-dependent enzyme, 5'-nucleotidase, relative to the control cells. Over a period of 7 days of exposure to zinc-deficient conditions, no changes in cell viability and growth, or in the cytoskeletal and cell adhesion systems, were found in HaCaT cells. At 7 days, however, induction of apoptosis was indicated by the presence of DNA fragmentation and expression of active caspase-3 in cells. These results demonstrate that apoptosis is the earliest detectable cellular change induced by zinc deficiency in HaCaT keratinocytes. Our observations account for many of the features of zinc deficiency, including the presence of degenerate nuclei, chromatin aggregates and abnormal organization of keratin, that may represent the later stages of apoptosis. In summary, a major causal role for apoptosis in the pathology of zinc deficiency in the skin is proposed. This role is consistent with the previously unexplained diverse range of degenerative cellular changes seen at the ultrastructural level in zinc-deficient keratinocytes.

The nationals may be heading into the wilderness, forever

Non-union rural workers may well be attracted to Kevin Rudd. IN RECENT decades, the Nationals have defied predictions of their demise. They have weathered the passing of agrarian socialism and the rapid decline in the farm population and - after the debacle of the "Joh for PM" campaign two decades ago - the party has successfully rallied around more limited goals of political survival and influence in the Coalition. Their parliamentary representation has fallen,...

Letters to a young Catholic, by George Weigel

With the Twentieth World Youth Day in Cologne on 16-21 August, this year, scheduled to be the first overseas visit of Pope Benedict XVI, it is timely to consider the latest book from George Weigel, (perhaps best known for his Witness to Hope: The Biography of John Paul II) in which he composes 14 letters specifically aimed at young Catholics, who, like many of their older counterparts, may well be wondering what it means to be a Catholic today.
