Export competitiveness in an oil and gas economy: the case of Trinidad and Tobago, 1985-2010

The oil and gas sector has led the economy of Trinidad and Tobago since the late 1970s and, more pronouncedly, since 2000, accounting for a large share of gdp, total exports and tax revenue. Its prospects in the medium term could be negatively affected, however, if oil and gas extraction expands in other countries, and if the United States attains energy self-sufficiency. This paper offers an analysis of the evolution and competitiveness of its oil and non-oil exports to both the United States and global markets, based on the revealed comparative advantage (rca) index used by eclac. Other foreign trade indicators are also included to determine the structure of the country’s trading relations. The period from 1985 to 2010 is analysed and the results presented are intended to advocate the diversification of Trinidad and Tobago’s exports into more dynamic and diversified markets.

Manejo de agrobiodiversidad en geoformas de restingas de várzea peruana, Iquitos/Perú

O estudo tem como objetivo avaliar e analisar o manejo da agrobiodiversidade em geoformas de restingas a partir da adaptabilidade da agrobiodiversidade praticada e da função que desempenham nas estratégias econômicas das famílias produtoras ribeirinhas. A relativa estabilidade das geoformas de restingas em função das erosões e inundações e seu grande potencial agro-biológico natural, explicam sua ocupação e uso intensivo dos solos desde muito antes do descobrimento e colonização da Amazônia pelos europeus (espanhóis e portugueses). A adaptabilidade da biodiversidade ribeirinha, como estratégia para produzir, manejar e conservar a diversidade dos recursos agrícolas, agroflorestais e outros recursos da agrobiodiversidade amazônica nas diferentes unidades de produção ou agroecosistemas (hortas, quintais, capoeira e bosques) de propriedade familiar, tem contribuído para alcançar auto-suficiência alimentar durante o ano e, principalmente, enfrentar ou diminuir riscos ocasionados por grandes inundações e pelo mercado (instabilidade de preços). O trabalho de campo foi realizado na várzea amazônica peruana, especificamente no Setor Muyuy, no sudeste da cidade de Iquitos.

O outro artificial e a alteridade na cultura pós-moderna

A presente pesquisa nasceu a partir de inquietações frente a um fenômeno que mostra a fascinação de homens que se relacionam com bonecas realistas – Real Dolls. Estas modelos simulam de forma perfeccionista altura, peso, forma, textura, cor, sexo, como se fossem “de carne e osso”, mas são “de metal e silicone”. As bonecas, contudo, não são meros brinquedos sexuais, pois adquirem muitas vezes a função de companhia, colocando em cheque a própria dimensão da alteridade. Esta relação construída artificialmente funciona, portanto, como um disparador de indagações acerca do outro e da atualidade. Assim, o objetivo deste estudo foi realizar uma discussão teórica, de cunho psicanalítico, a respeito da noção de alteridade na cultura contemporânea. Para isso, seguimos a trilha de questões chave: quem são o outro e a alteridade? Qual o seu lugar na cultura atual? Estaria a alteridade ameaçada pelo simulacro? Como pensar tal “negação da alteridade” sob o prisma da pós-modernidade? Seguindo este fio condutor, colocou-se em foco complexidades de um outro ao mesmo tempo familiar e estranho, ora configurado a partir de um “estrangeiro ao eu”, ora como um “eu estrangeiro” – remetendo à alteridade radical que constitui o eu, o inconsciente. A referência à atualidade se dá a partir do embate entre modernos e pós-modernos, onde se destaca a apreensão de uma sociedade regida pelo espetáculo narcísico e de um sujeito extremamente individualista, hedonista e consumista. Ganha espaço neste contexto a figura de um “outro artificial” que obedece a lógica perversa de predação que configura a primazia do eu em detrimento da alteridade. Desta forma, o outro se revela um artifício e a alteridade uma presença/ausência que joga com as aparências da atualidade e escamoteia seu “corpo” em uma aparente familiaridade. Assim, a alteridade persiste e desloca-se, fundamentando o outro como elemento que estrutura e desestrutura o sujeito, dando uma peculiaridade inevitavelmente “alteritária” para o mal-estar contemporâneo. Assim, o outro é, por um lado, descartável, pois a lógica narcísica proclama a autossuficiência do eu-ideal, enquanto, por outro lado, é a peça chave do espetáculo. É importante ponderar, portanto, que o lugar da alteridade está garantido, ainda que maquiado pela indiferença, ao contrário da impressão passada pelo panorama que deixa a entender sua extinção.

Análise termoeconômica de uma mini-estação de tratamento de esgoto com auto-suficiência energética

Avaliação da auto-suficiência energética de reatores anaeróbicos aplicados ao tratamento de resíduos de uma cervejaria em escala piloto

This project aimed to analyze the feasibility of the methane yield associated to the anaerobic digestion of brewery residues, checking whether the energetic balance of the system is favorable. The methane yield efficiency was calculated for the parameters of two papers that treated solids with a particle-size <1mm. Theses solids are not degraded in conventional treatment systems. Calculations were based in the reactions of anaerobic degradation of the macromolecules that compose brewery residues, considering the theoretical production and the effective production of methane. The results were 50.44% and 52.86%. Regarding to the energy balance of the anaerobic treatment, we noted the high influence of the selection and operating regime of electrical equipment over the potential energy. The best situation, in which the energetic self-sufficiency was reached, was observed when using the mixer under an intermittent regime (1min/h), without employing the heating recirculator, for the maximum organic loading of 4.0 gVS/L.day (days 248-258). In this case, the system would generate an amount of energy equal to 0.0356 kWh/day, able to overcome the energy required by the equipment in about 6.5 times. Moreover, we also noted the interference of the application of different solid loadings in the reactors, once the application of the higher organic load generated 5 times more energy than the application of the smaller one

Revisão dos principais radiofármacos utilizados no Brasil e suas aplicações na detecção e terapia de patologias

Radiopharmaceuticals are substances marked with radionuclides that can be used for detection and treatment of cancer, infections and inflammatory diseases. They emit several types of radiation through different decay routes, each radioisotope with its specific properties and uses. They can usually be produced from several different materials, by bombardment with particle beams in a nuclear research reactor or cyclotron, depending on their characteristics. Brazil has four public institutions which produce - or import - and distribute radiopharmaceuticals to hospitals and clinics throughout its territory. The largest such institution, Ipen, distributes 97% of radiopharmaceuticals used in the country. Some radiopharmaceuticals decay very quickly, meaning they must be produced and quickly administered to the patient in the same location, presenting a logistical challenge. Nuclear medicine in Brazil is a promising field and has been steadily growing, although rigid laws and a lack of qualified work force hinder Research and Development efforts for new radiopharmaceuticals. The construction of a new nuclear research reactor, in 2016, should generate self-sufficiency and economy in radiopharmaceutical production and avoid a future crisis in the supply of technetium-99m, the most important radioisotope, used in over 80% of procedures with radiopharmaceuticals.

EMERSON AS A ROMANTICIST

It was the romanticists who tended to write poetry of “autobiography,” who inquired of themselves concerning themselves, and assumed that the world was interested in what they found. Nor was the habit of self-consciousness regarding the poetic office let drop by their successors. That the words poet and poetry were so often on Emerson’s lips would be evidence enough to students of literature, in its changing temper and shifting modes, of his probable localization in time. It is also evidence of his relation to certain European movements of thought to which he gave—comparatively late in their currency and much tempered —American expression. In his doctrine of the superiority and the aloofness of the poet, of the latter’s severance from others to whom he yet bears messages of light, in his self-sufficiency and his sovereignty, his belief in the intrinsic goodness of nature and of man, and his concern with poetic thought rather than poetic form, Emerson may be termed the American representative of ideas which already had had wide circulation in Europe. In great part they emanated from Rousseau, and some of them, especially the gospel of the rights and the supremacy of the individual, had metamorphosed the politics and the map of Europe as well as its literature.

Influencia de las decisiones políticas en la rentabilidad del riego de especies forrajeras con aguas regeneradas

[ES] La escasa disponibilidad de agua a bajo precio y el actual régimen de ayudas del REA, ambos decididos a nivel político, explican que el autoabastecimiento forrajero sea actualmente un objetivo inalcanzable en Canarias. El Plan de Forrajeras de Canarias pretende contrarrestar esta realidad e incrementar su nivel de autoabastecimiento. La ayuda financiera que supone el REA reduce el importe a pagar por el forraje importado frente al producto local, condicionando la adopción de decisiones por parte de los ganaderos. De acuerdo a los cálculos realizados, reutilizando el agua en lugar de verterla, el cultivo de Maralfalfa podría ser competitivo frente a la importación, siendo financieramente viable con precios del agua en un rango de 0,20-0,30 €/m3

Uremic Neuropathy: Epiemiological Study in Hemodialysis Patients

Background/Aims. Uremic Neuropathy (UN) highly limits the individual self-sufficiency causing near-continuous pain. An estimation of the actual UN prevalence among hemodialysis patients was the aim of the present work. Methods. We studied 225 prevalent dialysis patients from two Italian Centres. The Michigan Neuropathy Score Instrument (MNSI), already validated in diabetic neuropathy, was used for the diagnosis of UN. It consisted of a questionnaire (MNSI_Q) and a physical-clinical evaluation (MNSI_P). Patients without any disease possibly inducing secondary neuropathy and with MNSI score  3 have been diagnosed as affected by UN. Electroneurographic (ENG) lower limbs examination was performed in these patients to compare sensory conduction velocities (SCV) and sensory nerve action potentials (SNAP) with the MNSI results. Results. Thirtyseven patients (16.4%) were identified as being affected by UN, while 9 (4%) presented a score <3 in spite of neuropathic symptoms. In the 37 UN patients a significant correlation was found between MNSI_P and SCV (r2 = 0.1959; p<0.034) as well as SNAP (r2 = 0.3454; p=0.027) both measured by ENG. Conclusions. UN is an underestimated disease among the dialysis population even though it represents a huge problem in terms of pain and quality of life. MNSI could represent a valid and simple clinical-instrumental screening test for the early diagnosis of UN in view of an early therapeutic approach.

Is a sustaining rod necessary for diverting loop ileostomy?

Objective: Whether or not a protective stoma reduces the rate of anastomotic leakage after distal colorectal anastomosis is still discussed controversially. It does however facilitate clinical management once leakage has occurred. Loop ileostomies seem to be associated with a lower morbidity and a better quality of life compared to loop colostomies. Generally, diverting loop ileostomies are secured at skin level by means of a supporting device in order to prevent retraction of the ileostomy into the abdomen. However, due to the supporting rod, difficulties may occur in applying a stoma bag correctly and leakage of faeces onto the skin may occur even with correct eversion of the afferent limb. Our aim was to compare morbidity and time to self-sufficient stoma-care in patients having a loop ileostomy with rod to those without rod. Methods: A total of 60 patients necessitating loop ileostomy were analyzed. Patients received surgery in of the two involved institutions according to inhouse standard procedures. 30 patients had an ileostomy with rod (VCHK Inselspital) and a further 30 without rod (KSW Winterthur). Morbidity and time to self-sufficiency regarding stoma care was analyzed during the first 90 postoperative days. Morbidity was determined according to a scoring system ranging from 0 to 4 points for any given set of possible complications (bleeding, necrosis, skin irritation, abscess, stenosis, retraction, fistula, prolapse, parastomal hernia, incomplete diversion), where 0 = no complication and 4 = severe complication. Continuous variables were expressed as median (95% Confidence Interval). For comparisons between the groups the Mann-Whitney U test was used, between categorical variables the X2 test was applied. Results: There were no significant differences in length of hospital stay or time to self-sufficient stoma-care between the groups. Although not significant, patients with a rod ileostomy had a tendency towards more stoma-related complications as well as stoma-related reoperations. The number of patients reaching total self-sufficiency regarding stoma care was higher after rodless ileostomy. Conclusion: According to our data, rodless ileostomies seemto fare just as well as those with a supporting rod, with equal morbidity rates and more patients reaching self-sufficient stoma care. Therefore routine application of a rod for diverting loop ileostomy seems unnecessary

Human Trafficking Victims and Their Children: Assessing Needs, Vulnerabilities, Strengths, and Survivorship

Given the increased awareness and attention to human trafficking, including the establishment of federal laws and policies, federally funded task forces that provide law enforcement responses, and specialized victim services, it is important to assess the impact of these procedures and services on survivors/victims of international human trafficking and their immigrant children. By federal definition, certified victims of international human trafficking are eligible for all services provided to refugees in this country, including reunification with their minor children. This research is based on a qualitative study conducted in Austin and Houston, Texas with human trafficking victims/survivors. The project’s goal was to gain an understanding of the needs of human trafficking survivors after their rescue, their overall integration into American life, and the subsequent needs of their immigrant children after reunification. The project objectives examined the factors that either promote or hinder self-sufficiency, the determination of social service needs, and policy and practice recommendations to strengthen survivors, their children and their families living both locally and abroad. For this project, nine (n = 9) in-depth interviews were conducted with adult foreign-born victims of human trafficking. Researchers gathered data using a semi-structured questionnaire that queried about factors that promote or hinder victims’ services and needs. Interviews were conducted in participants’ homes using bilingual research staff and/or trained interpreters, were digitally-recorded, and subsequently transcribed. Participation in this study was completely voluntary. Specific steps were taken to ensure that the participants’ identities were protected. Open coding of data was utilized and the data were subsequently organized or grouped into properties and later developed into contextual themes around the research questions. The findings are grounded with the use of direct quotes from participants. As a result of progressive U.S. policy, many victims of human trafficking are being reunited with their minor children. Immigrant children are one of the largest and fastest growing populations in the U.S. and for a variety of reasons are vulnerable to exploitation. Research also indicates that victims of trafficking are identified by traffickers because of their perceived “vulnerabilities” or lack of opportunities (Clark, 2003). Therefore, it is important that practices and policies are developed to address the unique needs of these families with an eye toward positive outcomes for parent and child safety and well-being. Social service providers are provided a toolkit that may be utilized before and during the reunification period.

The story of Community preference for food security

"Préférence communautaire" is an in-built notion of the CAP since its inception with the Treaty of Rome (1957). Its’ simple objective laid down at the Stresa Conference in 1958 is to prefer community produce over imports wherever possible, while at the same time promoting agricultural exports and FDI (“vocation exportatrice de l’Europe”). Does this contrast or correlate with the notion of “food sovereignty” which originated in 1996 as a notion of small farmer self-sufficiency (Via Campesina), and which now has found its way into the official EC discourse? Recent CAP reforms indeed seem to continue banking on border protection and on the occasional export subsidy. Nonetheless, coming together with claims to mitigate climate change, “food sovereignty” à la CAP fails to acknowledge efficiency losses at home and negative spillover effects on the right to food of food exporting developing countries. This chapter asks whether new non-tariff and domestic support measures are just new wine in the old cask of fortress Europe, together with the FDI promotion instruments of the FED and others. Might the increasing dynamics and new challenges of agricultural trade and investment lead to lower market and production shares for European farms? It concludes that in the medium term the WTO Green Box has the only legal and effective tools to promote EU agriculture and food.
