Escenarios de colonialismo y (de) colonialidad en la construcción del Ser Negro. Apuntes sobre las relaciones de género en comunidades negras del Pacífico colombiano (Tema Central)

Las relaciones de género en las comunidades negras están mediadas por el legado esclavista a la que fue sometida la población afro descendiente en las Américas, éstas se forjaron en la construcción histórica del ser negros. Aun la estructura patriarcal fue una potestad de los amos esclavistas, no del negro despojado de sí mismo, tanto el hombre como la mujer negro-negra esclavos fueron mercancías, su sexualidad y sus relaciones hicieron parte de la función de mercantil que le infringieron los amos, la maternidad fue un oficio y el hombre negro un reproductor de bienes. El derecho a Ser es el primer principio en la propuesta organizativa del Proceso de Comunidades Negras –PCN– como estrategia de dignificación del ser negros y de descolonización interna y externa desde el sujeto mismo hacia y desde la sociedad que le rodea.

El conflicto interno armado en Colombia. Antecedentes y perspectivas (Tema Central)

Este artículo reflexiona sobre los conflictos que aquejan a la sociedad colombiana, teniendo en consideración a los actores y a los elementos objetivos y estructurales que los condicionan. Se parte de entender al conflicto no como algo patológico sino como un espacio normal de divergencia social. Además de ello, el autor analiza la relación entre política y violencia en Colombia, considera los elementos de tipo interno y externo que han determinado esta relación, enfatiza sobre los rasgos de exclusión social y política que han caracterizado a Colombia, y analiza los escenarios posibles de resolución del conflicto colombiano.

Historia de la cooperación monetaria y financiera internacional y su importancia en el desarrollo del mercado financiero internacional (Tema Central)

La historia de la cooperación monetaria y financiera internacional da cuenta de la forma en que el sistema monetario influyó en el mercado financiero internacional. En las páginas que siguen se podrá observar cómo los países intentaron su equilibrio interno y externo, a través de sus diversos mecanismos monetarios internacionales. El período patrón oro (1870-1914), merece atención, porque las tentativas subsiguientes de reformar el sistema monetario internacional, sobre la base de tipos de cambio fijos, se la construyó sobre la fortaleza del patrón oro. Los años de entreguerras (1918-1939) fueron marcados por la tendencia en la impresión desbocada de billetes, lo que trajo altos niveles de inflación. El Acuerdo Bretton Woods (1945-1973), que crea el Fondo Monetario Internacional, fue el resultado de la enorme preocupación de los gobiernos de cuarenta y cuatro países, por los acontecimientos económicos desastrosos en el período de entreguerras.

Política exterior y cooperación: del discurso a la acción (Otros Temas)

Este artículo presenta el escenario de la política exterior y cooperación internacional previo al gobierno de Rafael Correa, tomando a la cooperación dentro del Plan Colombia e Iniciativa Regional Andina como ejemplo de la misma. Igualmente, la autora plantea la existencia de un paradigma que rige tanto la política interna como externa del Ecuador y como éste se vincula con el ALBA. Finalmente, confronta el discurso con la realidad comercial y de cooperación de varios países de Sudamérica.

Soberanía e integración en América Latina (Tema Central)

El artículo hace referencia al desarrollo de la soberanía y las nuevas formas de regionalismo en América Latina. En esta lógica, el “nuevo regionalismo” surge en los últimos años bajo condiciones internas y externas que se traducen en el surgimiento de nuevas formas regionales como ALBA, UNASUR, CELAC. Adicionalmente, se recalca la persistencia de obstáculos a la integración regional como la soberanía nacional, pero al mismo tiempo se plantea enfrentar los mencionados desafíos a través de cambios conceptuales del término soberanía, en función de una estrategia a largo plazo que genere una gobernanza regional.

Algunas características de los programas antárticos de India y China (Tema Central)

This paper states that even though the Antarctic Treaty is a remarkable instrument for peaceful collaboration and scientific research, it is, basically, a by-product of the Cold War that reaffirms a particular status quo. This paper explores whether the ATS will meet the needs of an emerging world order. Particularly, the paper evaluates the ATS in the face of new global challenges, both internal and external to the Antarctic Treaty System (ATS) itself, as well as power shifting processes on a world scale, climate change and the changing interests of new states. China is a key component in understanding this issue because its Antarctic engagement is entering a new phase one that challenges current multilateral provisions. China’s Antarctic program will be analyzed within the framework of International Relations approaches and theories.

Using aircraft measurements to determine the refractive index of Saharan dust during the DODO Experiments

Much uncertainty in the value of the imaginary part of the refractive index of mineral dust contributes to uncertainty in the radiative effect of mineral dust in the atmosphere. A synthesis of optical, chemical and physical in-situ aircraft measurements from the DODO experiments during February and August 2006 are used to calculate the refractive index mineral dust encountered over West Africa. Radiative transfer modeling and measurements of broadband shortwave irradiance at a range of altitudes are used to test and validate these calculations for a specific dust event on 23 August 2006 over Mauritania. Two techniques are used to determine the refractive index: firstly a method combining measurements of scattering, absorption, size distributions and Mie code simulations, and secondly a method using composition measured on filter samples to apportion the content of internally mixed quartz, calcite and iron oxide-clay aggregates, where the iron oxide is represented by either hematite or goethite and clay by either illite or kaolinite. The imaginary part of the refractive index at 550 nm (ni550) is found to range between 0.0001 i to 0.0046 i, and where filter samples are available, agreement between methods is found depending on mineral combination assumed. The refractive indices are also found to agree well with AERONET data where comparisons are possible. ni550 is found to vary with dust source, which is investigated with the NAME model for each case. The relationship between both size distribution and ni550 on the accumulation mode single scattering albedo at 550 nm (ω0550) are examined and size distribution is found to have no correlation to ω0550, while ni550 shows a strong linear relationship with ω0550. Radiative transfer modeling was performed with different models (Mie-derived refractive indices, but also filter sampling composition assuming both internal and external mixing). Our calculations indicate that Mie-derived values of ni550 and the externally mixed dust where the iron oxide-clay aggregate corresponds to the goethite-kaolinite combination result in the best agreement with irradiance measurements. The radiative effect of the dust is found to be very sensitive to the mineral combination (and hence refractive index) assumed, and to whether the dust is assumed to be internally or externally mixed.

The 2003 CAP Reform: Accommodating WTO Pressures

In 2003, the EU agreed a major reform of the common agricultural policy (CAP). Its centrepiece was a new Single Payment Scheme (SPS). Policy concerns at the time involved the budget, EU enlargement to the East, the WTO negotiations, and a perception (articulated by Commissioner Fischler) that there should be a shift of budget funds from CAP's Pillar 1 (price and income support) to Pillar 2 (rural development). We outline these concerns, conclude that the WTO was the main driving force of the reforms, set out the key parameters of the new support scheme, and outline some thoughts on the durability of the reformed CAP in the face of continued internal and external pressures.

Post occupancy evaluation of a building employing windcatchers for summer ventilation

A combined windcatcher and light pipe (SunCatcher) was installed in the seminar room at the University of Reading, UK. Monitoring of indoor environment in real weather conditions was conducted to evaluate the application of windcatchers for natural ventilation. In addition, a subjective occupancy survey was undertaken. External weather conditions and internal indoor air quality indicators were recorded. The “tracer-gas decay” method using SF6 was used to establish air change rate for various conditions. The results indicated that the ventilation rate achieved through the windcatcher depends on the difference between internal and external air temperatures, and on wind speed and direction, in agreement with other published work in the area. The indoor air quality parameters were found to be within acceptable levels when the windcatcher was in operation. The measured air change rate was between 1.5ac/h and 6.8ac/h. Occupants’ questionnaires showed 75 per cent satisfaction with the internal conditions and welcomed the installation of the systems in UK buildings.

Innovation in facilities management: from trajectories to ownership

Purpose – Innovation in facilities management (FM) is a complex process as FM is a diverse discipline. This paper aims to use innovation trajectories to explore this complex process through the introduction of a technology innovation in two FM services of security and workspace management. It also aims to consider the discourse of individuals within their trajectory to understand their positions toward the innovation. Design/methodology/approach – A two-year case study was conducted and it was based in an in-house FM department that was part of a financial institution. The specific methods used for the paper were semi-structured interviews with key participants of the project. Critical discourse analysis was used to examine the data. Findings – Individuals who were involved in introducing the technology to the FM department were both internal and external to FM as innovation in FM does not happen in isolation to the organisation. Innovation trajectories were often intertwined or occurred simultaneously during the process of a project which sometimes resulted in conflict. Tensions within the discourse of ownership of the project were particularly apparent as this discourse had a power dimension in driving the project through to implementation. Research limitations/implications – The research is limited by being a single case study so it is not possible to generalise findings but the findings may have resonances with other organisations. Originality/value – The paper presents an original idea about how to understand innovation processes in FM services.

An examination of actors that impact technology introduction to FM

Developing and implementing a technology for Facilities Management (FM) can be a complex process. This is particularly the case when a technology impacts on an organisation as a whole. There are often a number of relevant actors, internal and external to FM, who should be engaged. This engagement is guided by the strategy of the organisation which is led by top management decisions. Indeed, it is top management who have the final decision to implement a technology. Actors of top management and other relevant actors will have their own discourses toward the implementation of the technology based on how they foresee the technology befittingly benefitting the organisation. This paper examines actors who play a relevant and necessary part in supporting and implementing a technology to FM. It examines how an actor’s discourse toward the project inhibits or speeds up the implementation of a technology. The methods used for this paper are based on a two year case study in a FM department where a technology development was observed and interviews with key participants were conducted. Critical discourse analysis is used to analyse the data. Prominent discourses that emerge from the data are emphasised during the process of introducing the technology. This research moves beyond focusing purely on project successes but examines the difficulties and the hurdles that must be overcome to reach a successful technology implementation.

The lay of the trilobite: rereading May Kendall

The impact of Darwin's theory of evolution by natural selection on the culture of late Victorian England and on the development of Western thought at large is at once widely acknowledged and hotly contested. In this essay, I revisit the question of what difference an understanding of Darwin's ideas, their reception and their afterlife within evolutionary biology makes to how we read Victorian poetry. I suggest that there are three distinct ways of approaching poetry after Darwin. The first is to examine poems in their own cultural context, considering how they respond to the scientific discourses of their time in the light of internal and external evidence as to the specific sources of each poet's knowledge of those discourses. The second is to ground an interpretative framework in Darwinism's insights into human biology itself. The third is to explore how a given poem's responses to the philosophical issues raised by Darwin's thinking, including questions of ethics and theology, give its readers a possible model for their own responses to the same concerns today. I suggest too that the limitations of each approach may be best overcome by bringing them together. I go on to explore the potential of the first and third approaches through a reading of May Kendall's poem 'The Lay of the Trilobite' in a series of different contexts, from its first appearance in 'Punch', through her first collection Dreams to Sell, to her essays on Christian ethics from the 1880s and 1890s

Towards a resolution of ‘the paradox of the plankton’: a brief overview of the proposed mechanisms

In plankton ecology, it is a fundamental question as to how a large number of competing phytoplankton species coexist in marine ecosystems under a seemingly-limited variety of resources. This ever-green question was first proposed by Hutchinson [Hutchinson, G.E., 1961. The paradox of the plankton. Am. Nat. 95, 137–145] as ‘the paradox of the plankton’. Starting from Hutchinson [Hutchinson, G.E., 1961. The paradox of the plankton. Am. Nat. 95, 137–145], over more than four decades several investigators have put forward varieties of mechanisms for the extreme diversity of phytoplankton species. In this article, within the boundary of our knowledge, we review the literature of the proposed solutions and give a brief overview of the mechanisms proposed so far. The proposed mechanisms that we discuss mainly include spatial and temporal heterogeneity in physical and biological environment, externally imposed or self-generated spatial segregation, horizontal mesoscale turbulence of ocean characterized by coherent vortices, oscillation and chaos generated by several internal and external causes, stable coexistence and compensatory dynamics under fluctuating temperature in resource competition, and finally the role of toxin-producing phytoplankton in maintaining the coexistence and biodiversity of the overall plankton population that we have proposed recently. We find that, although the different mechanisms proposed so far is potentially applicable to specific ecosystems, a universally accepted theory for explaining plankton diversity in natural waters is still an unachieved goal.

Interactive learning in UK construction practice: examining the role of BIM process standards

From a construction innovation systems perspective, firms acquire knowledge from suppliers, clients, universities and institutional environment. Building information modelling (BIM) involves these firms using new process standards. To understand the implications on interactive learning using BIM process standards, a case study is conducted with the UK operations of a multinational construction firm. Data is drawn from: a) two workshops involving the firm and a wider industry group, b) observations of practice in the BIM core team and in three ongoing projects, c) 12 semi-structured interviews; and d) secondary publications. The firm uses a set of BIM process standards (IFC, PAS 1192, Uniclass, COBie) in its construction activities. It is also involved in a pilot to implement the COBie standard, supported by technical and management standards for BIM, such as Uniclass and PAS1192. Analyses suggest that such BIM process standards unconsciously shapes the firm's internal and external interactive learning processes. Internally standards allow engineers to learn from each through visualising 3D information and talking around designs with operatives to address problems during construction. Externally, the firm participates in trial and pilot projects involving other construction firms, government agencies, universities and suppliers to learn about the standard and access knowledge to solve its specific design problems. Through its BIM manager, the firm provides feedback to standards developers and information technology suppliers. The research contributes by articulating how BIM process standards unconsciously change interactive learning processes in construction practice. Further research could investigate these findings in the wider UK construction innovation system.

Planning in the face of ‘deep divisions’: a view from Beirut, Lebanon

This article discusses planning in the global South-East while focusing on the specific context of social divides, political turmoil and conflict situations. The article proposes a five-way framework based on political science and planning to theory to analyse such contexts. The article explores the case of Beirut, Lebanon that has undergone several episodes of internal and external conflicts resulting in a society splintered along sectarianism. Three Two case studies of open urban spaces and their public activities are analysed using the five-way framework The discussion indicates how economic liberalism that is prevalent in countries of the South-East, along with place-based identities, interest-based identities, consensus orientated processes and institutionalism might facilitate a cultivation of deep values away from a narrowly constructed identity. The article argues that planners should understand the options for positive action that aim to bridge deep divisions and suggests that the five-way framework provides a reference for contextualising in different ways to suit particular contexts. Therefore, the framework is not necessarily restricted to the South-East but could be applicable to any context which manifests deep divisions.
