An assessment of the economic impact of climate change on the tourism sector in the Bahamas

The Bahamas is at great risk and vulnerability given its geographical features as a low-lying, sea encircled country. If projected sea level rise is reached by 2050, between 10-12% of territory will be lost, especially in coastal zones where the main tourism assets are located. Vulnerability could also be manifested if flight carbon emission taxes are established in the main source markets, representing an economic threat to the tourism sector for the islands. The impact of climate change on main tourism demand variables will cause some losses to the country‟s income and government revenues. This would be acting conjointly with some local threats to tourism assets and trends in future global tourism demand. The second and no less important threat is tropical cyclones, which may be associated with raising sea level. Estimations posited the amount of losses in excess of 2400 million US$ for the four decades under examination. It is to be pointed out that there is still a lack of comparatively accurate data collection and analysis on this subject, a point deserving more attention in order to deepen the understanding of, and to extract better lessons from these extreme events. In the same period, total estimated impacts of progressive climate change are between 17 and 19 billions of B$ with estimated discount rates applied. The Bahamas is a Small Island Developing State with low growth on GHG emissions (second in Latin America), as well as a relative short capacity to lower emissions in the future. The country has a relative delay in the application of renewable energy systems, a solution that, provided documented studies on-site, might turn out to be fundamental in the country‟s efforts to establish mitigation related policies. The Bahamas currently has institutions and organizations that deal with climate change-related issues and an important number of measures and courses of action have been set up by the government. Nevertheless, more coordination among them is needed and should include international institutions. This coordination is essential even for the first steps, i.e. to conduct studies with a bottom-up approach in order to draw more accurate programs on adaptation and mitigation. It is fundamental for tourism to keep track of potential losses in tourist attractions (and to act accordingly), related to correspondent losses in biodiversity, water resources and coastal erosion. Also, actions to fight climate change impacts might improve the islands security standards, quality of living and protect cultural and heritage assets. These elements may definitely shape the future of the country‟s competitiveness as a tourism destination. It is possible and necessary to decide about the options with good cost-benefit ratio and reasonable payback periods, notwithstanding that cost-benefit analysis requires more refined and accurate data to provide precise and locally adapted options.

Jamaica: Macro-socio-economic assessment of the damage done by flood rains and landslides May 2002

This assessment was prepared for the Government of Jamaica following the significant damages to social and economic infrastructure and productive sectors as a result of a period of sustained and unusual rainfall associated with the convergence of a tropical wave over Jamaica and an area of high pressure to the north of the island resulting in periods of heavy and sustained rainfall over the period May 22 – June 2, 2002. A request for technical assistance was directed to the Economic Commission for Latin America and the Caribbean (ECLAC) Subregional Headquarters for the Caribbean, on May 31, by the Planning Institute of Jamaica. In view of the recent training provided by the ECLAC Caribbean team in the use of the ECLAC methodology to a multi-disciplinary group of 58 persons spanning several sectors, it was felt that this event, while most unfortunate, nonetheless provided an opportune moment for the Jamaican “trainees” to utilize the skills transferred and to apply the methodology which had been taught. Consequently, ECLAC fielded a team of five persons a few days after the request had been made , to give the Jamaican counterpart team the opportunity to collect data of the type and using an approach well suited to the preparation of assessments such as this.

Use of synthetic aperture radar for recognition of Coastal Geomorphological Features, land-use assessment and shoreline changes in Bragança coast, Pará, Northern Brazil

Imagens de radar de abertura sintética (SAR) vem sendo bem mais utilizadas do que antes nas aplicações de geociências em regiões tropicais úmidas. Nesta investigação, uma imagem RADARSAT-1, na banda C, polarização HH adquirida em 1998 foi usada para o mapeamento costeiro e avaliação da cobertura da terra na área de Bragança, norte do Brasil. Imagem do radar aerotransportado GEMS-1000, na banda X, polarização HH, adquirida em 1972 durante o projeto RADAM foi também utilizada para avaliar as variações costeiras ocorridas nas últimas três décadas. A pesquisa tem confirmado a utilidade da imagem RADARSAT-1 para o mapeamento geomorfológico e avaliação da cobertura da terra, particularmente em costas de manguezal de macromaré. Além disso, um novo método para estimar as variações da linha de costa baseado na superposição de vetores extraídos de diferentes imagens SAR, com alta acurácia geométrica, tem mostrado que a planície costeira de Bragança tem estado sujeita a severa erosão responsável pelo recuo de aproximadamente 32 km² e acreção de 20 km², resultando em uma perda de área de manguezal de aproximadamente 12 km². Como perspectiva de aplicação, dados SAR orbitais e aerotransportados provaram ser uma importante fonte de informação tanto para o mapeamento geomorfológico, quando para o monitoramento de modificações costeiras em ambientes tropicais úmidos.

Comparison of two computerized procedures for the assessment of color discrimination in Cebus apella

Color vision consists of the discrimination of objects based on their spectral composition. Among primates, the majority of Platyrrhini monkeys are estimated to have polymorphic and sex-linked dichromacy. The objective of this study was to compare the results produced by different equipment and software for the assessment of tri- and dichromatic conditions in one male and two female Cebus apella. Three experiments were programmed. In Experiment 1, verifying the trichromatic condition of one female subject and dichromatic condition of the remainder of the subjects was possible using an adapted version of the Cambridge Colour Test. Experiment 2 confirmed the results of Experiment 1 using a different array of stimuli of the same test. Experiment 3, which produced results similar to Experiment 2, consisted of a test developed for a standard computer system using stimuli with color properties similar to the ones used in the previous experiment. Favorable conditions for the assessment of color vision in Platyrrhini can be built with low-cost equipment and software. Once data have been gathered with additional subjects and new stimulus arrangements have been tested and confirmed, the procedure can be used for the evaluation of other Platyrrhini species for which behavioral color discrimination data are currently lacking.

Correlação entre parâmetros estimados pelos testes Colour Assessment and Diagnosis e Cambridge Colour Test na avaliação da discriminação de cores

Os testes Colour Assessment and Diagnosis (CAD) e Cambridge Colour Test (CCT) têm sido amplamente utilizados em pesquisas básicas e clínicas, devido à alta sensibilidade e especificidade de seus resultados. Estes testes utilizam diferentes paradigmas de estimulação para estimar os limiares de discriminação de cor. Pouco se sabe sobre a relação de cada paradigma na avaliação da discriminação de cor nesses testes. Sendo assim, este trabalho objetiva comparar os parâmetros de avaliação da discriminação de cor estimados pelos testes CAD e CCT em sujeitos tricromatas e com discromatopsia congênita. Foram avaliados 59 sujeitos tricromatas e 38 sujeitos discromatópsicos (16 protans, 22 deutans) com idade média de 26,32 ± 8,9 anos. Foram testados 66 sujeitos nos testes CAD e CCT, 29 sujeitos no teste CAD e 2 sujeitos no teste CCT. O fenótipo da visão de cores de todos os sujeitos foi determinado através de uma bateria de testes psicofísicos e a estimativa dos limiares de discriminação de cor foi avaliada pelos testes CAD e CCT. Os dados de limiares de discriminação de cor foram ajustados a funções de elipse. Os critérios analisados para cada sujeito foram: a área da elipse, o ângulo de rotação e tamanho dos vetores protan, deutan e tritan. Para cada um dos parâmetros foi realizada: estatística descritiva, análise da dispersão dos parâmetros entre os testes CAD e CCT e dos parâmetros em conjunto, razão entre os parâmetros, correlação dos parâmetros a três modelos matemáticos e análise de concordância. Os parâmetros de área e tamanho dos vetores deutan e tritan do subgrupo tricromata; área e tamanho do vetor tritan do subgrupo protan; e tamanho dos vetores protan e tritan do subgrupo deutan apresentaram equivalência entre os resultados de ambos os testes. Os parâmetros de área, ângulo de rotação e tamanho dos vetores protan e tritan apresentaram concordância de medidas entre os testes CAD e CCT. Fatores como as localizações distintas das coordenadas centrais dos testes CAD e CCT e a disposição espacial dos vetores no espaço de cor da CIE 1976 no teste CCT podem ter influenciado na determinação de limiares de discriminação cromática de ambos os testes. Apesar de utilizarem paradigmas distintos na configuração da estimulação, os testes CAD e CCT são equiparáveis.

Assessment of the mechanics of a tissue-engineered rat trachea in an image-processing environment

OBJECTIVES: Despite the recent success regarding the transplantation of tissue-engineered airways, the mechanical properties of these grafts are not well understood. Mechanical assessment of a tissue-engineered airway graft before implantation may be used in the future as a predictor of function. The aim of this preliminary work was to develop a noninvasive image-processing environment for the assessment of airway mechanics.METHOD: Decellularized, recellularized and normal tracheas (groups DECEL, RECEL, and CONTROL, respectively) immersed in Krebs-Henseleit solution were ventilated by a small-animal ventilator connected to a Fleisch pneumotachograph and two pressure transducers (differential and gauge). A camera connected to a stereomicroscope captured images of the pulsation of the trachea before instillation of saline solution and after instillation of Krebs-Henseleit solution, followed by instillation with Krebs-Henseleit with methacholine 0.1 M (protocols A, K and KMCh, respectively). The data were post-processed with computer software and statistical comparisons between groups and protocols were performed.RESULTS: There were statistically significant variations in the image measurements of the medial region of the trachea between the groups (two-way analysis of variance [ANOVA], p<0.01) and of the proximal region between the groups and protocols (two-way ANOVA, p<0.01).CONCLUSIONS: The technique developed in this study is an innovative method for performing a mechanical assessment of engineered tracheal grafts that will enable evaluation of the viscoelastic properties of neo-tracheas prior to transplantation.

Integrated analysis environment for the Movement Assessment Battery for Children

Developmental Coordination Disorder (DCD), a chronic and usually permanent condition found in children, is characterized by motor impairment that interferes with a child's activities of daily living and with academic achievement. One of the most popular tests for the quantitative diagnosis of DCD is the Movement Assessment Battery for Children (MABC). Based on the Battery's standardized scores, it is possible to identify children with typical development, children at risk of developing DCD, and children with DCD. This article describes a computational system we developed to assist with the analysis of results obtained in the MABC test. The tool was developed for the web environment and its database provides integration of MABC data. Thus, researchers around the world can share data and develop collaborative work in the DCD field. In order to help analysis processes, our system provides services for filtering data to show more specific sets of information and present the results in textual, table, and graphic formats, allowing easier and more comprehensive evaluation of the results.

Assessment of postoperative pain after unilateral mastectomy using two different surgical techniques in dogs

Background: There are few studies reporting pain and postoperative analgesia associated with mastectomy in dogs. The aim of this study was to evaluate postoperative pain after unilateral mastectomy using two different surgical techniques in the dog.Findings: Twenty female dogs were assigned (n=10/group) to undergo unilateral mastectomy using either the combination of sharp and blunt dissection (SBD) or the modified SBD (mSBD) technique, in which the mammary chain is separated from the abdominal wall entirely by blunt (hand and finger) dissection except for a small area cranial to the first gland, in a prospective, randomized, clinical trial. All dogs were premedicated with intramuscular acepromazine (0.05 mg/kg) and morphine (0.3 mg/kg). Anesthesia was induced with intravenous ketamine (5 mg/kg) and diazepam (0.25 mg/kg), and maintained with isoflurane. Subcutaneous meloxicam (0.2 mg/kg) was administered before surgery. Postoperative pain was evaluated according to the University of Melbourne pain scale (UMPS) by an observer who was blinded to the surgical technique.. Rescue analgesia was provided by the administration of intramuscular morphine (0.5 mg/kg) if pain scores were > 14 according to the UMPS. Data were analyzed using t-tests and ANOVA (P>0.05). There were no significant differences between the groups for age, weight, extubation time, and duration of surgery and anesthesia (P>0.05). There were no significant differences for postoperative pain scores between groups. Rescue analgesia was required in one dog in each group.Conclusions: The two surgical techniques produced similar surgical times, incidence of perioperative complications and postoperative pain. Multimodal analgesia is recommended for treatment of postoperative pain in dogs undergoing unilateral mastectomy.
