Crítica a los mecanismos de cooperación entre Colombia y Perú para enfrentar la oferta de drogas ilícitas en la frontera (2003-2012)

El objetivo de esta investigación es explicar la forma en que la oferta de drogas ilícitas en la frontera ha configurado los mecanismos de cooperación entre Colombia y Perú de 2003 a 2012. Éste será desarrollado a través de los conceptos de cooperación (Keohane 1984) y securitización (Buzan 1998), que condujeron al estudio del proceso de coordinación política en tres etapas (Balzacq 2010): qué se dice en los acuerdos de cooperación entre Colombia y Perú, cómo han actuado los Estados en la frontera y cómo ese comportamiento ha afectado la posibilidad de coordinación política con Ecuador y Brasil dentro del micro complejo regional de seguridad. De esta manera, se probará que el tema de la oferta de drogas ilícitas en la frontera permanece en el campo politizado en la agenda colombo-peruana, mientras que la posibilidad de vínculos entre grupos armados organizados de ambos Estados está securitizada.

A new challenge for malaria control in Brazil: asymptomatic Plasmodium infection - a review

The evolution of malaria in Brazil, its morbidity, the malaria control programs, and the new challenges for these programs in the light of the emergence of asymptomatic infection in the Amazon region of Brazil were reviewed. At least six Brazilian research groups have demonstrated that asymptomatic infection by Plasmodium is an important impediment to malaria control, among mineral prospectors in Mato Grosso and riverside communities in Rondônia and, in our group, in the middle and upper reaches of the Negro river, in the state of Amazonas. Likewise, other researchers have studied the problem among indigenous communities in the Colombian, Peruvian, and Venezuelan parts of the Amazon basin, adjacent to Brazil. The frequency of positive results from the polymerase chain reaction (PCR) among asymptomatic individuals has ranged from 20.4 to 49.5%, and the presence of Plasmodium in the thick blood smears, from 4.2 to 38.5%. Infection with Anopheles darlingi has also been demonstrated by xenodiagnosis among asymptomatic patients with positive PCR results. If a mean of 25% is taken for the asymptomatic infection caused by Plasmodium sp. in the Amazon region of Brazil, malaria control will be difficult to achieve in that region with the measures currently utilized for such control.

Impacto del conflicto armado en la frontera colombo-ecuatoriana y las implicaciones en sus relaciones diplomáticas a partir de la implementación del Plan Colombia hasta diciembre de 2009

Históricamente, las fronteras colombianas han sido porosas, frágiles y descuidadas desde una perspectiva política. La extrema pobreza y la ausencia de instituciones estatales han dejado a las poblaciones vulnerables ante diversos actores armados y a merced de las actividades ilícitas, que inevitablemente se desbordan y afectan los territorios vecinos. El desborde de los efectos del conflicto armado a territorio ecuatoriano, los enfrentamientos e incursiones del ejército colombiano, y la presencia de actores no estatales como los grupos al margen de la ley, han hecho que las relaciones bilaterales se minen, dañando lo que alguna vez fue una cordialidad constructiva entre Colombia y Ecuador. Para analizar esta problemática, se utilizaron las teorías de las relaciones internacionales de Interdependencia y seguridad cooperativa.

Viabilidad de implementación de una zona libre en la zona de frontera colombo-venezolana, sector de tienditas

La zona fronteriza de Norte de Santander ha sido un territorio que a lo largo de la historia ha tenido periodos de grandes superávits para la población de la zona, así como periodos de crisis. La región fundamenta su vida económica, social y cultural en el intercambio que se realiza con Venezuela. En esta investigación mediante el análisis del estado actual de la región y por medio del uso de herramientas y análisis administrativos se estudiara la viabilidad de implementar una Zona Libre en la zona de frontera colombo-venezolana, sector de Tienditas. Con herramientas como las 5 fuerzas de Porter, pronósticos cuantitativos, diagramas de flujo, análisis cualitativos, etc. se brindara un mayor entendimiento de las fortalezas y debilidades de la región, flujo de productos y servicios en la frontera y las propuestas de mejoramiento, localización de la zona, sectores potenciales y legislación o propuestas que generarían un valor agregado a esta zona.

La presente investigación analiza en qué medida el estado de las relaciones políticas bilaterales con Ecuador han determinado los alcances y desafíos en los mecanismos de integración y desarrollo fronterizos terrestre colombiano, específicamente la ZIF y la COVIEC dentro del periodo 2001 – 2010.

Bilateral trade between New Zealand & the pacific alliance: perspectives and possibilities for further trade engagement

Due to the rapid and effective success of countries in the Pacific Rim for the last two decades, current world trade attention has been focussed on what appears to be the common vision of the ‘Pacific Century’. Reducing attention from the Atlantic and focusing it on the Pacific represents a new challenge for countries touching this ocean. The main Latin American economies bordering the pacific have taken upon this challenge with the creation of the Pacific Alliance in 2011. In this way, Chile, Colombia, Mexico and Peru intend to penetrate and increase trade with the region by forming a coalition. The Pacific Alliance has attracted international attention, interest and support from nations around the world, counting 32 countries as observers; 7 are actually located in the region and six of them rank amongst the Top 15 world economies. As is expected, the possibility of closer trade engagement with big players such as China, India, Japan, South Korea or Australia absorb the main attention of media, governments and academics alike, leaving behind other feasible and possible opportunities unattended. That is precisely the case of New Zealand and its favourable commerce opportunities with the Pacific Alliance. The following document will study the major trends and variations in trade between New Zealand, the Pacific Alliance and its members between 2010 and 2014. Proving that mutual trade is most likely to keep on growing.

Die Gletscher der bolivianischen Anden, Verbreitung von Gletschern und neuzeitlichen Moränen in der Cordillera Apolobamba Cololo Region (Ostkordillere)

The uniform triangulation of the whole glacierized area of the Eastern Cordillera of Bolivia provided the first comparable geometrie basis for an accurate photogrammetric height evaluation of glaciers in the mountain range from the far south up to the Peruvian border. A total of 1775 glaciers, larger than 0.1 ha, were recorded in 16 mountain ranges ofthe East- ern Cordillera. Snow lines in the outer tropics can now be analysed with an accuracy of European standards. In spite of the widemeshed network of meteorological stations this allows a more pre- eise climatic differentiation to be made, particularly at high altitude sites. The methods and results of the analysis are described. Because of these results it becomes necessary to revise and refine previous concepts of the spatial distribution of climatic phenomena. Characteristics of glaciers in the Bolivian Cordillera obviously depend on the NE to SW decline in precipitation. The snow lines which are found at an altitude of 4500 m on the north- eastern slope directed towards the Yungas climb up to 5200 m on the lee slope towards the Alti- plano. The N to S increase in snowline elevation is not as significant as expected. With some res- ervation a 100 m fall in the snowline elevation in the Bolivian Cordillera can be explained by an increase in precipitation of about 50 mm.

Onchocerciasis in Ecuador: Prevalence of Infection on the Ecuador-Colombia Border in the Province of Esmeraldas

The prevalence of onchocerciasis infection was determined in communities on 7 rivers located in the northern area of the cantón San Lorenzo, province of Esmeraldas. Diagnosis of the infection was obtained by skin biopsies and recombinant-antigen based-serology. No evidence of infection was detected in 9 communities studied along the Río Mataje, which forms the frontier between Ecuador and Colombia, nor in 10 adjacent communities located on 5 interior rivers. Evidence for Onchocerca volvulus infection was found in 4 communities on the Río Tululví with the following prevalence: La Boca (3.5% by biopsy and 3.9% by serology), Guayabal (9.1% by both biopsy and serology), La Ceiva (51.5% by biopsy and 53% by serology), and Salidero (4% by biopsy and 7.7% by serology). A few individuals in these communities were seropositive for O. volvulus in the absence of detectable dermal microfilariae: these might harbor very light or prepatent infections. No clinical disease attributable to onchocerciasis was found. The infected communities will be included in the ivermectin-based National Control Program for the disease, with no evidence of the infection having extended north of the Ecuadorian-colombian border

Tectonomagmatic evolution of Western Amazonia: Geochemical characterization and zircon U-Pb geochronologic constraints from the Peruvian Eastern Cordilleran granitoids

The results of a coupled, in situ laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) U-Pb study on zircon and geochemical characterization of the Eastern Cordilleran intrusives of Peru reveal 1.15 Ga of intermittent magmatism along central Western Amazonia, the Earth's oldest active open continental margin. The eastern Peruvian batholiths are volumetrically dominated by plutonism related to the assembly and breakup of Pangea during the Paleozoic-Mesozoic transition. A Carboniferous-Permian (340-285 Ma) continental arc is identified along the regional orogenic strike from the Ecuadorian border (6 degrees S) to the inferred inboard extension of the Arequipa-Antofalla terrane in southern Peru (14 degrees S). Widespread crustal extension and thinning, which affected western Gondwana throughout the Permian and Triassic resulted in the intrusion of the late- to post-tectonic La Merced-San Ramon-type anatectites dated between 275 and 220 Ma, while the emplacement of the southern Cordillera de Carabaya peraluminous granitoids in the Late Triassic to Early Jurassic (220-190 Ma) represents, temporally and regionally, a separate tectonomagmatic event likely related to resuturing of the Arequipa-Antofalla block. Volcano-plutonic complexes and stocks associated with the onset of the present Andean cycle define a compositionally bimodal alkaline suite and cluster between 180 and 170 Ma. A volumetrically minor intrusive pulse of Oligocene age (ca. 30 Ma) is detected near the southwestern Cordilleran border with the Altiplano. Both post-Gondwanide (30-170 Ma), and Precambrian plutonism (691-1123 Ma) are restricted to isolated occurrences spatially comprising less than 15% of the Eastern Cordillera intrusives. Only one remnant of a Late Ordovician intrusive belt is recognized in the Cuzco batholith (446.5 +/- 9.7 Ma) indicating that the Famatinian arc system previously identified in Peru along the north-central Eastern Cordillera and the coastal Arequipa-Antofalla terrane also existed inboard of this parautochthonous crustal fragment. Hitherto unknown occurrences of late Mesoproterozoic and middle Neoproterozoic granitoids from the south-central cordilleran segment define magmatic events at 691 +/- 13 Ma, 751 +/- 8 Ma, 985 +/- 14 Ma, and 1071-1123 +/- 23 Ma that are broadly coeval with the Braziliano and Grenville-Sunsas orogenies, respectively. Our data suggest the existence of a continuous orogenic belt in excess of 3500 km along Western Amazonia during the formation of Rodinia, its ``early'' fragmentation prior to 690 Ma, and support a model of reaccretion of the Paracas-Arequipa-Antofalla terrane to western Gondwana in the Early Ordovician with subsequent detachment of the Paracas segment in form of the Mexican Oaxaquia microcontinent in Middle Ordovician. A tectonomagmatic model involving slab detachment, followed by underplating of cratonic margin by asthenospheric mantle is proposed for the genesis of the volumetrically dominant Late Paleozoic to early Mesozoic Peruvian Cordilleran batholiths.

Indigenous knowledges and power in friction with human rights and development discourses : the case of the Witoto Ethnic Safeguarding Plan in the Colombian Amazon

Cette thèse analyse les négociations interculturelles des Gens du Centre (groupe amazonien multi-ethnique) avec les discours universels de droits humains et de développement mobilisés par l’État colombien. L’analyse se concentre sur le Plan de sauvegarde ethnique Witoto chapitre Leticia (ESP), qui est un des 73 plans formulés et implémentés par l’État colombien pour reconnaître les droits des peuples autochtones en danger par le déplacement forcé causé par les conflits armés internes. J’analyse l’ESP à travers la notion de friction (Tsing, 2005) qui fait référence aux caractéristiques complexes, inégalitaires et changeantes des rencontres contemporaines entre les différences des savoirs locaux et globaux. Mon analyse se base aussi sur des approches foucaldiennes et/ou subalternes de pouvoir comme la recherche anticoloniale et de la décolonisation, les perspectives critiques et contre-hégémoniques des droits humains, le post-développement, et les critiques du féminisme au développement. L’objectif de la thèse est d’analyser les savoirs (concepts de loi, de justice et de développement); les logiques de pensée (pratiques, épistémologies, rôles et espaces pour partager et produire des savoirs); et les relations de pouvoir (formes de leadership, associations, réseaux, et formes d’empowerment et disempowerment) produits et recréés par les Gens du Centre au sein des frictions avec les discours de droits humains et du développement. La thèse introduit comment la région habitée par les Gens du Centre (le Milieu Amazone transfrontalier) a été historiquement connectée aux relations inégalitaires de pouvoir qui influencent les luttes actuelles de ce groupe autochtone pour la reconnaissance de leurs droits à travers l’ESP. L’analyse se base à la fois sur une recherche documentaire et sur deux terrains ethnographiques, réalisés selon une perspective critique et autoréflexive. Ma réflexion méthodologique explore comment la position des chercheurs sur le terrain influence le savoir ethnographique et peut contribuer à la création des relations interculturelles inclusives, flexibles et connectées aux besoins des groupes locaux. La section analytique se concentre sur comment le pouvoir circule simultanément à travers des échelles nationale, régionale et locale dans l’ESP. J’y analyse comment ces formes de pouvoir produisent des sujets individuels et collectifs et s’articulent à des savoirs globaux ou locaux pour donner lieu à de nouvelles formes d’exclusion ou d’émancipation des autochtones déplacés. Les résultats de la recherche suggèrent que les Gens du Centre approchent le discours des droits humains à travers leurs savoirs autochtones sur la « loi de l’origine ». Cette loi établit leur différence culturelle comme étant à la base du processus de reconnaissance de leurs droits comme peuple déplacé. D’ailleurs, les Gens du Centre approprient les discours et les projets de développement à travers la notion d’abondance qui, comprise comme une habileté collective qui connecte la spiritualité, les valeurs culturelles, et les rôles de genre, contribue à assurer l’existence physique et culturelle des groupes autochtones. Ma thèse soutient que, même si ces savoirs et logiques de pensée autochtones sont liés à des inégalités et à formes de pouvoir local, ils peuvent contribuer à des pratiques de droits humains et de développement plurielles, égalitaires et inclusives.

Leadership and performance in multicultural business environments a qualitative study in German-Colombian teams

Multicultural leadership is a topic a great interest in nowadays globalized work environment. Colombia emerges as an attractive marketplace with appealing business opportunities, especially for German enterprises. After presenting Colombia’s current political, social and economic situation, the thesis elaborates the complex subject of cultural differences while focusing on the peculiarities of German and Colombian national cultures. The resulting implications for a team’s collaboration and leader effectiveness are theoretically supported with reference to the landmark studies of Hofstede and GLOBE. By utilizing semi-structured interview techniques, a qualitative research enriches the previous findings and gives an all-encompassing insight in German-Colombian teamwork. The investigation identifies distinctive behavioral patterns and relations, which imply challenges and factors of success for multicultural team leaders. Finally, a categorical analysis examines the influence of cultural traits on team performance and evaluates the effectiveness of the applied leadership style.

Late-career international migration and reproductive work. A comparison between Peruvian and Ukrainian women in the Southern Europe

Research on the relationship between reproductive work and women´s life trajectories including the experience of labour migration has mainly focused on the case of relatively young mothers who leave behind, or later re-join, their children. While it is true that most women migrate at a younger age, there are a significant number of cases of men and women who move abroad for labour purposes at a more advanced stage, undertaking a late-career migration. This is still an under-estimated and under-researched sub-field that uncovers a varied range of issues, including the global organization of reproductive work and the employment of migrant women as domestic workers late in their lives. By pooling the findings of two qualitative studies, this article focuses on Peruvian and Ukrainian women who seek employment in Spain and Italy when they are well into their forties, or older. A commonality the two groups of women share is that, independently of their level of education and professional experience, more often than not they end up as domestic and care workers. The article initially discusses the reasons for late-career female migration, taking into consideration the structural and personal determinants that have affected Peruvian and Ukrainian women’s careers in their countries of origin and settlement. After this, the focus is set on the characteristics of domestic employment at later life, on the impact on their current lives, including the transnational family organization, and on future labour and retirement prospects. Apart from an evaluation of objective working and living conditions, we discuss women’s personal impressions of being domestic workers in the context of their occupational experiences and family commitments. In this regard, women report varying levels of personal and professional satisfaction, as well as different patterns of continuity-discontinuity in their work and family lives, and of optimism towards the future. Divergences could be, to some extent, explained by the effect of migrants´ transnational social practices and policies of states.

Growth parameters and mortality rate of the Scomber japonicus peruanus (Jordán & Hubb, 1925) along the Peruvian coast, South Pacific

The growth parameters and the mortality rates of the Scomber japonicus peruanus (Chub mackerel) were studied based on monthly data of frequency of fork length classes obtained from commercial landings off the Peruvian coast from 1996 to 1998. The asymptotic body length and growth rate values obtained by the ELEFAN I (Electronic Length Frequency Analysis) ranged from 40.20 cm to 42.20 cm and from 0.38 to 0.39, respectively. The oscillation amplitude was 0.60; the Winter point values varied from 0.50 to 0.60 and the performance index from 2.79 to 2.84. The total mortality rate of the Chub mackerel obtained by the linearized catch curve oscillated between 1.68 and 3.35. The rate of fishing mortality varied from 1.16 to 2.78 and the exploitation rate from 0.68 to 0.84. The annual rate of natural mortality estimated by the Pauly's method ranged from 0.52 to 0.53. The results obtained allow us to conclude that the longevity of the Chub mackerel was slightly over seven years.

Effects of flooding of the River Paraná on the temporal activity of Anopheles (Nyssorhynchus) darlingi Root (Diptera: Culicidae), at the border state of Mato Grosso do Sul and São Paulo, Brazil

INTRODUCTION: Study of the temporal activity of malaria vectors during the implantation of a hydroelectric power station on the River Paraná, intended to generate electrical energy. The river separates the States of São Paulo and Mato Grosso do Sul, in Brazil. The objective was to verify whether alterations occurred in the wealth and diversity indices of Anopheles, following two successive floods, extended to the temporal activity and nycthemeral rhythm followed over a five year period. METHODS: Mosquito capture was performed monthly using the Human Attraction Technique and Shannon Traps. The first, executed for 24h, provided the nycthemeral rhythm and the second, lasting 15h, permitted the tracking of Anopheles during the two floods. RESULTS: The bimodal pattern of Anopheles darlingi defined before these floods was modified throughout the environment interventions. The same effect had repercussions on the populations of An albitarsis s.l., An triannulatus and An galvaoi. Activity prior to twilight was less affected by the environment alterations. CONCLUSIONS: The dam construction provoked changes in Anopheles temporal activity patterns, permitting classification of the area as an ecologically steady and unstable situation. Differences observed in Anopheles behavior due to the capture methods revealed the influence of solo and multiple attractiveness inside the populations studied.

Border figure detection using a phase oscillator network with dynamical coupling

Oscillator networks have been developed in order to perform specific tasks related to image processing. Here we analytically investigate the existence of synchronism in a pair of phase oscillators that are short-range dynamically coupled. Then, we use these analytical results to design a network able of detecting border of black-and-white figures. Each unit composing this network is a pair of such phase oscillators and is assigned to a pixel in the image. The couplings among the units forming the network are also dynamical. Border detection emerges from the network activity.
