Improving the organisation and commercialisation of small coffee and cocoa producers in the Northern Amazon Region of Ecuador

Coffee and cocoa represent the main sources of income for small farmers in the Northern Amazon Region of Ecuador. The provinces of Orellana and Sucumbios, as border areas, have benefited from investments made by many public and private institutions. Many of the projects carried out in the area have been aimed at energising the production of coffee and cocoa, strengthening the producers’ associations and providing commercialisation infrastructure. Improving the quality of life of this population threatened by poverty and high migration flows mainly from Colombia is a significant challenge. This paper presents research highlighting the importance of associative commercialisation to raising income from coffee and cocoa. The research draws on primary information obtained during field work, and from official information from the Ministry of Agriculture. The study presents an overview of current organisational structures, initiatives of associative commercialisation, stockpiling of infrastructure and ownership regimes, as well as estimates for both ‘robusta’ coffee and national cocoa production and income. The analysis of the main constraints presents different alternatives for the implementation of public land policies. These policies are aimed at mitigating the problems associated with the organisational structure of the producers, with processes of commercialisation and with environmental aspects, among others.

Essential role of the N-terminal region of TFII-I in viability and behavior

Background: GTF2I codes for a general intrinsic transcription factor and calcium channel regulator TFII-I, with high and ubiquitous expression, and a strong candidate for involvement in the morphological and neuro-developmental anomalies of the Williams-Beuren syndrome (WBS). WBS is a genetic disorder due to a recurring deletion of about 1,55-1,83 Mb containing 25-28 genes in chromosome band 7q11.23 including GTF2I. Completed homozygous loss of either the Gtf2i or Gtf2ird1 function in mice provided additional evidence for the involvement of both genes in the craniofacial and cognitive phenotype. Unfortunately nothing is now about the behavioral characterization of heterozygous mice. Methods: By gene targeting we have generated a mutant mice with a deletion of the first 140 amino-acids of TFII-I. mRNA and protein expression analysis were used to document the effect of the study deletion. We performed behavioral characterization of heterozygous mutant mice to document in vivo implications of TFII-I in the cognitive profile of WBS patients. Results: Homozygous and heterozygous mutant mice exhibit craniofacial alterations, most clearly represented in homozygous condition. Behavioral test demonstrate that heterozygous mutant mice exhibit some neurobehavioral alterations and hyperacusis or odynacusis that could be associated with specific features of WBS phenotype. Homozygous mutant mice present highly compromised embryonic viability and fertility. Regarding cellular model, we documented a retarded growth in heterozygous MEFs respect to homozygous or wild-type MEFs. Conclusion: Our data confirm that, although additive effects of haploinsufficiency at several genes may contribute to the full craniofacial or neurocognitive features of WBS, correct expression of GTF2I is one of the main players. In addition, these findings show that the deletion of the fist 140 amino-acids of TFII-I altered it correct function leading to a clear phenotype, at both levels, at the cellular model and at the in vivo model.

Global alcohol exposure estimates by country, territory and region for 2005--a contribution to the Comparative Risk Assessment for the 2010 Global Burden of Disease Study.

AIMS: This study aimed to estimate the prevalence of life-time abstainers, former drinkers and current drinkers, adult per-capita consumption of alcohol and pattern of drinking scores, by country and Global Burden of Disease region for 2005, and to forecast these indicators for 2010. DESIGN: Statistical modelling based on survey data and routine statistics. SETTING AND PARTICIPANTS: A total of 241 countries and territories. MEASUREMENTS: Per-capita consumption data were obtained with the help of the World Health Organization's Global Information System on Alcohol and Health. Drinking status data were obtained from Gender, Alcohol and Culture: An International Study, the STEPwise approach to Surveillance study, the World Health Survey/Multi-Country Study and other surveys. Consumption and drinking status data were triangulated to estimate alcohol consumption across multiple categories. FINDINGS: In 2005 adult per-capita annual consumption of alcohol was 6.1 litres, with 1.7 litres stemming from unrecorded consumption; 17.1 litres of alcohol were consumed per drinker, 45.8% of all adults were life-time abstainers, 13.6% were former drinkers and 40.6% were current drinkers. Life-time abstention was most prevalent in North Africa/Middle East and South Asia. Eastern Europe and Southern sub-Saharan Africa had the most detrimental pattern of drinking scores, while drinkers in Europe (Eastern and Central) and sub-Saharan Africa (Southern and West) consumed the most alcohol. CONCLUSIONS: Just over 40% of the world's adult population consumes alcohol and the average consumption per drinker is 17.1 litres per year. However, the prevalence of abstention, level of alcohol consumption and patterns of drinking vary widely across regions of the world.

Evolutionary analysis of genes of two pathways involved in placental malaria infection

Placental malaria is a special form of malaria that causes up to 200,000 maternal and infant deaths every year. Previous studies show that two receptor molecules, hyaluronic acid and chondroitin sulphate A, are mediating the adhesion of parasite-infected erythrocytes in the placenta of patients, which is believed to be a key step in the pathogenesis of the disease. In this study, we aimed at identifying sites of malaria-induced adaptation by scanning for signatures of natural selection in 24 genes in the complete biosynthesis pathway of these two receptor molecules. We analyzed a total of 24 Mb of publicly available polymorphism data from the International HapMap project for three human populations with European, Asian and African ancestry, with the African population from a region of presently and historically high malaria prevalence. Using the methods based on allele frequency distributions, genetic differentiation between populations, and on long-range haplotype structure, we found only limited evidence for malaria-induced genetic adaptation in this set of genes in the African population; however, we identified one candidate gene with clear evidence of selection in the Asian population. Although historical exposure to malaria in this population cannot be ruled out, we speculate that it might be caused by other pathogens, as there is growing evidence that these molecules are important receptors in a variety of host-pathogen interactions. We propose to use the present methods in a systematic way to help identify candidate regions under positive selection as a consequence of malaria.

Geochemical and geothermal study of springs in the Ossola-Simplon Region

Geological, hydrogeological and geochemical surveys were carried out in the Piedilago area (Ossola-Simplon region) in order to investigate the geothermal resources present in this area. Following these surface exploration efforts an exploratory geothermal well of 248 m was drilled in 1991. It discharges a thermal water with temperatures up to 43 degrees C and calcium (sodium) sulphate composition with a TDS close to 1350 mg/l. Chemical geothermometers suggest a reservoir temperature close to 45 degrees C indicating that the well virtually produces the pure uncooled thermal water. The Piedilago ex-ample is here considered as the departure point to establish both general criteria for further geothermal investigations in young mountains chains and taking into consideration all the available data on geology and fluid geochemistry of thermal systems in the Ossola-Simplon region, to constrain a geothermal model for the Lower Pennine Zone.

Alpine tectonic evolution of a Jurassic subduction-accretionary complex: Deformation, kinematics and 40Ar/39Ar age constraints on the Mesozoic low-grade schists of the Circum-Rhodope Belt in the eastern Rhodope-Thrace region, Bulgaria-Greece

Deformation of the Circum-Rhodope Belt Mesozoic (Middle Triassic to earliest Lower Cretaceous) low-grade schists underneath an arc-related ophiolitic magmatic suite and associated sedimentary successions in the eastern Rhodope-Thrace region occurred as a two-episode tectonic process: (i) Late Jurassic deformation of arc to margin units resulting from the eastern Rhodope-Evros arc-Rhodope terrane continental margin collision and accretion to that margin, and (ii) Middle Eocene deformation related to the Tertiary crustal extension and final collision resulting in the closure of the Vardar ocean south of the Rhodope terrane. The first deformational event D-1 is expressed by Late Jurassic NW-N vergent fold generations and the main and subsidiary planar-linear structures. Although overprinting, these structural elements depict uniform bulk north-directed thrust kinematics and are geometrically compatible with the increments of progressive deformation that develops in same greenschist-facies metamorphic grade. It followed the Early-Middle Jurassic magmatic evolution of the eastern Rhodope-Evros arc established on the upper plate of the southward subducting Maliac-Meliata oceanic lithosphere that established the Vardar Ocean in a supra-subduction back-arc setting. This first event resulted in the thrust-related tectonic emplacement of the Mesozoic schists in a supra-crustal level onto the Rhodope continental margin. This Late Jurassic-Early Cretaceous tectonic event related to N-vergent Balkan orogeny is well-constrained by geochronological data and traced at a regional-scale within distinct units of the Carpatho-Balkan Belt. Following subduction reversal towards the north whereby the Vardar Ocean was subducted beneath the Rhodope margin by latest Cretaceous times, the low-grade schists aquired a new position in the upper plate, and hence, the Mesozoic schists are lacking the Cretaceous S-directed tectono-metamorphic episode whose effects are widespread in the underlying high-grade basement. The subduction of the remnant Vardar Ocean located behind the colliding arc since the middle Cretaceous was responsible for its ultimate closure, Early Tertiary collision with the Pelagonian block and extension in the region caused the extensional collapse related to the second deformational event D-2. This extensional episode was experienced passively by the Mesozoic schists located in the hanging wall of the extensional detachments in Eocene times. It resulted in NE-SW oriented open folds representing corrugation antiforms of the extensional detachment surfaces, brittle faulting and burial history beneath thick Eocene sediments as indicated by 42.1-39.7 Ma Ar-40/Ar-39 mica plateau ages obtained in the study. The results provide structural constraints for the involvement components of Jurassic paleo-subduction zone in a Late Jurassic arc-continental margin collisional history that contributed to accretion-related crustal growth of the Rhodope terrane.

Trends in prevalence, awareness, treatment and control of hypertension in the Republic of Seychelles (African region) between 1989 and 2013

Objective: We assessed the awareness, treatment and control of hypertension in the Seychelles between 1989 and 2013. In the Seychelles, heath care is free to all inhabitants within a national health system, inclusive all hypertension medications. Design and method: Four surveys were conducted in 1989, 1994, 2004 and 2013 (Seychelles Heart Studies I, II, III and IV) in random samples of the population aged 25-64 (N >1000 and participation rate >75% in each sur acceptance of the program, though no objective index could be calculated. In total, 15% of device measurements were above high normal values and would correspond to either newly diagnosed HNT (second measurement required) or to poorly controlled known HTN. It should be stressed that 53 women without HTN who completed the questionnaire had abnormal BP values, including the 29 women who also contacted the research team. It could be speculated that approximately 2% of women would be first diagnosed with HTN following the completion of the initial phase of the screening program. Conclusions: Hypertension screening in the hair salon setting was proved to be conveniently applicable and well accepted both by owners and by customers and could lead to the new diagnosis of hypertension for 2% of the female clients. Further research is warranted to assess the effectiveness of the program.

La toxicologie forensique, une discipline scientifique en plein essor [Forensic toxicology, a growing scientific discipline]

La recherche de substances ayant pu jouer un rôle direct ou indirect dans la cause de la mort ou ayant pu modifier le comportement d'un individu constitue la mission première de la toxicologie forensique. L'augmentation de la consommation de substances illégales et de médicaments dans les sociétés modernes a fait connaître à la toxicologie forensique un essor très important ces dernières décennies. D'autre part, les développements technologiques analytiques ont permis d'obtenir des outils très sensibles et spécifiques pour la recherche et le dosage d'une multitude de substances dans une grande variété d'échantillons biologiques, parfois présentes à des concentrations très faibles, conséquence d'une dose équivalente à la prise d'une seule unité galénique. Forensic toxicology has to bring evidence of substances that could have been involved directly or indirectly in the cause of death or that could influence the behaviour of somebody. The increase of the consumption of illegal and legal drugs in modern societies during last decades gave a boost to forensic toxicology. Moreover, improvement with analytical technology gave tools with high degrees of sensitivity and specificity for the screening and quantification of a large amount of substances in various biological specimens, even with very low concentration resulting of a single dose of medication.

Measurement of nurses' workload in an oncology outpatient clinic

The growing demand and the degree of patient care in oncological outpatient services, as well as the complexity of treatment have had an impact on the workload of nurses. This study aimed at measuring the workload and productivity of nurses in an oncological outpatient service. An observational study using a work sampling technique was conducted and included seven nurses working in an oncological outpatient service in the south-eastern region of Brazil. A total of 1,487 intervention or activity samples were obtained. Nurses used 43.2% of their time on indirect care, 33.2% on direct care, 11.6% on associated activities, and 12% on personal activities. Their mean productivity was 88.0%. The findings showed that nurses in this service spend most of their time in indirect care activities. Moreover, the productivity index in this study was above that recommended in the literature.

China´s Economic Security Police Towards ASEAN From

After the economic reforms of 1978, China started rising very fast and started engaging other countries in the region which has served to increase its confidence in the region. In the post cold war period, China was seen as a big threat for the region because of its claims on the South China Sea. Nevertheless, this image was eliminated when China engaged ASEAN and other multilateral and regional organizations. This paper is studying China’s economic and security policies towards ASEAN. Globalization Theory is the theory being used to explain the nature of China-ASEAN relations. This research paper argues that China’s rise is promoting peace in the region. With the engagement policy, China started promoting trade and security co operations based on mutual benefits and dialogues for the peaceful resolutions of the disputes in the region. This contributed greatly to improve China’s image in the region. Additionally, China’s posture during the economic crises of 1997 also greatly contributed to improve its image. Thus, the rise of China is providing opportunity to the other countries in East Asia. Chapter One: Background On China-ASEAN Relations The use of Soft Power and engagement policy by the Chinese government has helped to change China’s image in the region. By using these policies China has been able to clear the feeling of suspicion and mistrust among the Asian states. China has increased its participation in multilateral and regional organizations, such as ASEAN. Due to this China has been able to promote economic and security co-operation among countries in the region. Thus, from being a potential threat China became a potential co-operative partner. Chapter Two: A Look into ASEAN ASEAN was originally formed on 8th August 1967 in Bangkok, Thailand, by Indonesia, Malaysia, the Philippines, Singapore and Thailand. Nevertheless, ASEAN was not the first regional group created to act as forum for dialogue between the leaders of different countries. Thought, it is the only one which could work in the region. The aim of the foundation of ASEAN was to promote peace and stability in the Abstract 2 region and also contain the spread of communism in Southeast Asia. For this reason, China did not engage ASEAN until 1990. However, in 1978 with the establishment of the open up policy China started engaging other countries. It started building trust among its neighboring countries by using soft power. By 1992, China formalized its diplomatic ties with ASEAN as a group. The diplomatic ties between China and ASEAN focus on multilateralism and co-operation as the best way for a more peaceful Asia and the search for common security. Thus, security in the region is promoted through economic co-operation among the states. Therefore the relation between China – ASEAN emphasizes the five principles of peaceful coexistence, mutual benefits in economic co-operation, dialogue promoting trust and the peaceful settlement of disputes. Chapter Three: China-ASEAN Economic Relations Since 1978 The economic reform of 1978 has greatly contributed to the economic development of China. After the adoption of the open up policy, China has been able to establish economic and trade relations with the outside world. The realist school of thought had predicted that Asia will not be stable in the post cold war period. Nevertheless, this has not been the case in Asia. China is growing peacefully with the co-operation of countries in the region. China is establishing strong ties with its neighboring countries. China and ASEAN relations focus on mutual benefit instead of being a zero sum game. Thus these relations are aimed at encouraging trust and economic co-operation in the region. China and ASEAN have agreed on Free Trade to assure that the two parties benefit from the co-operation. The ACFTA will have a great impact on economic, political and security issues. This will enable China to increase its influence in Asia and counterbalance the influences that Japan and U.S have in the region. Chapter Four: China ASEAN Relations in the Security Perspective This Chapter is about China and ASEAN relations on security issue. The new security issues of the post cold war period need to be solved in multilateral way. China as a major power in the region, through its engagement policy has solved most Abstract 3 of the disputes in the region using multilateral means. China has also found ways to solve the dispute over Spratly Islands peacefully, through dialogue using ASEAN. Additionally, China signed the Treaty of Amity in 2003, promoted security initiatives through ARF, Declaration on Conduct of Parties in the South China Sea and documents covering non-traditional security threats, economic co-operation and agricultural co-operation in November 2002, and the Joint Declaration on Strategic. Chapter Five: Finding and Analysis This chapter provides a quantitative and qualitative analysis of the date collected throughout this research. It provides an analysis of how the rise of China is promoting peace in the region. China has been promoting mutual beneficial trade and security co-operation which has increased its influence in the region. China has also been able to solve most of the territorial and border dispute in the region through ASEAN. Thus, ASEAN has amended China’s relations with other countries in the region. Therefore, China’s foreign policy in the region has a big impact in shaping the dynamic relations in East Asia. Conclusion and Recommendations This paper concluded that the relationships between China and ASEAN are contributing to peace in the region. After China engaged ASEAN, it has been able to promote multilateral trade based on mutual benefit. This is clearly emphasized by the CAFTA. Additionally, China has solved most of the dispute in the region. It has also found way for a peaceful resolution of the dispute over Spratly Island. Nowadays, the ASEAN countries don’t see China as a threat to the region. Nevertheless, they’ve adopted deterrence measures such as establishing diplomatic relations with other big powers in the region to assure that the region continues to grow peacefully. Concerning this deterrence measures, I recommend as another way for a continued peaceful growth, the resolution of the outstanding dispute.

A Comparison of the Management Models of Protected Areas between China and the Southern African Region

A Comparison of the Management Models of Protected Areas between China and the African South Region allows reading and evaluating the similarities and differences in the use of management model as a management tool for protected areas in China and South African Region. Specifically, some positive and negative features of the management approaches for the two regions. Secondary data was collected from various related literature such as policy documents, students‟ dissertations/thesis, scientific articles and magazines. Based on the method above, the study found out that China's first nature reserve was the Dingus Mountain Nature Reserve in Zhaoqing, Guangdong province established in 1956. By the end of 2005, about 2,349 nature reserves of various kinds were set up throughout the country, covering a total area of 149.95 million ha and accounting for 15 percent of the total land territory. The study further found that Southern Africa has approximately 4,390 protected areas out of 11487920 total land areas and Eastern Africa has approximately 1838144 protected areas, which is equivalent to 15.0% of the total land areas. South Africa in this region had its first declared natural park in 1926 after Paul Kruger (a war hero) had alerted the authorities of the extinguishing threat of some animal species of region.
