report of the workshop on boosting SME development and competitiveness in the Caribbean

The Economic Commission for Latin America and the Caribbean (ECLAC) Subregional Headquarters for the Caribbean, in collaboration with the Division of Production, Productivity and Management at ECLAC Headquarters in Chile, convened a one-day workshop on “Boosting SME Development and Competitiveness in the Caribbean”, at the Subregional Headquarters for the Caribbean in Port of Spain on 14 May 2009. The workshop was the culmination of country studies that were carried out under an Italian Government-funded project to assess the policies, institutions and instruments for dynamic Small and Medium Enterprises (SME) development and competitiveness in Jamaica, Suriname and Trinidad and Tobago. The aim was to use the lessons learned from the three country studies to inform policy and practice in the other member countries of the Caribbean Development and Cooperation Committee (CDCC). The main objectives of the workshop were to: (a) share and discuss the findings of the country studies and lessons learned; (b) provide a forum for high quality discussion of the policy environment, instruments, business development and support services required for successful SME development in the Caribbean; and (c) map out a strategy for moving from analysis and recommendation to policy implementation and business changes in order to promote a dynamic and competitive SME sector. The workshop aimed to arrive at practical solutions to major constraints and a weighting of key actions in order of priority of implementation, by adopting a problem-solving approach. Participants at the workshop included representatives of key SME support institutions in the region, actual SMEs and academic researchers. The list of participants and provisional programme are annexed to this report.

Escolas diferenciadas praticam um ensino de ciências diferenciado para melhor!?: o que dizem os estudantes sobre o ensino de ciências de uma escola de aplicação

O presente estudo é relativo às práticas docentes no ensino de ciências em uma Escola de Aplicação tida como escola diferenciada positivamente em termos da qualidade de suas práticas de ensino, das condições de trabalho de seus professores e pelo suposto interesse de atualização permanente para assegurar aprendizagem significativa aos estudantes e prepará-los para exercer a cidadania. Meu objetivo foi identificar parâmetros de diferenciação qualitativa do ensino na área de Ciências, considerando justamente que a experimentação pedagógica foi uma das vertentes que dirigiu a criação de ‘escolas de aplicação’ no País. Esta investigação se desenvolve em uma modalidade de pesquisa narrativa por meio da qual se objetiva evidenciar, a partir do relato dos estudantes sobre suas experiências no ensino de ciências, como se configuram as práticas de ensino, especialmente em termos de: a) seleção de conteúdos, b) abordagens teórico-metodológicas do ensino, c) interação professor aluno e aluno-aluno em classe e fora desta, bem como d) práticas, critérios e procedimentos de avaliação do ensino e da aprendizagem. Procurei investigar como os alunos percebem e que valores atribuem às práticas de ensino de Ciências, configuradas especialmente como “boas aulas de ciências”. Tendo como foco os relatos dos estudantes de 5ª a 8ª séries da escola pesquisada, sobre as práticas de ensino de ciências que vivenciam, assumo como premissa, que estes possuem idéias, percepções e concepções acerca do processo de ensino e de aprendizagem. As análises por mim procedidas apontam para uma prática de ensino reprodutiva e memorativa, pouco diferente das práticas tradicionais usuais das escolas comuns. No tocante à natureza das aulas e à temática dessas aulas, pouco se valoriza os conhecimentos prévios dos estudantes, predominando um tipo de aula em que os alunos passivamente se limitam a observar o trabalho docente, reproduzem ou repetem quando solicitados aspectos de conteúdos/conhecimento informativo de temas e assuntos das ciências fechados no programa a cumprir e descontextualizados, sem qualquer relação com a realidade, com o mundo em que os estudantes vivem. A guisa de conclusão, considero que as possibilidades e os limites desse ensino obsoleto e ultrapassado de Ciências evidenciados pelos estudantes põem em questão o ensino atual da área e colocam desafios para esta escola de aplicação e para seus professores, em função principalmente das condições privilegiadas de uma escola de aplicação. Torna-se imprescindível que se retome tais práticas de ensino para atualizá-las ao se buscar refletir coletivamente sobre os conteúdos que podem ser significativos para os estudantes, sua relação com o mundo de hoje, bem como sobre as metodologias para tratamento dos conteúdos das Ciências na perspectiva da efetiva construção da aprendizagem significativa dos estudantes, preparando-os de fato para a cidadania.

A geração de resíduos sólidos urbanos e sua influência na gestão urbano-ambiental municipal de Sorocaba/SP

In Brazil, rates of urban solid waste generation increase proportionally more than the annual growing of the population. The government, from its federal authority to the municipal spheres, faces increasing challenges for Urban and Environmental management regarding to solid waste in general and, in particular, municipal solid waste. Financial problems added to public health problems that worsen with the serious environmental impacts generated every year. In August 2010 Brazil the PNRS (National Policy on Solid Waste) was approved and sanctioned in which represented a true watershed in the country as a legal framework extremely ambitious and visionary. This work presents the successes and challenges that the municipality of Sorocaba/SP is facing after more than three years of PNRS sanctioned to conduct an Urban and Environmental management suited to the new legal bases towards the subject of solid waste. The results show a large gap between the content proposed by the law and the technical, financial and temporal reality to practical implementation by the municipal government. New legislation and federal incentives, consortiums among the cities, flexible deadlines and environmental education at all levels are certainly some proposals to catalyze processes that aim to solve and overcome the challenges of solid waste

Transmission of Chlamydia trachomatis through sexual partnerships: a comparison between three individual-based models and empirical data

Chlamydia trachomatis is the most common bacterial sexually transmitted infection (STI) in many developed countries. The highest prevalence rates are found among young adults who have frequent partner change rates. Three published individual-based models have incorporated a detailed description of age-specific sexual behaviour in order to quantify the transmission of C. trachomatis in the population and to assess the impact of screening interventions. Owing to varying assumptions about sexual partnership formation and dissolution and the great uncertainty about critical parameters, such models show conflicting results about the impact of preventive interventions. Here, we perform a detailed evaluation of these models by comparing the partnership formation and dissolution dynamics with data from Natsal 2000, a population-based probability sample survey of sexual attitudes and lifestyles in Britain. The data also allow us to describe the dispersion of C. trachomatis infections as a function of sexual behaviour, using the Gini coefficient. We suggest that the Gini coefficient is a useful measure for calibrating infectious disease models that include risk structure and highlight the need to estimate this measure for other STIs.

Testing Wisconsin asphalt mixtures for the 2002 AASHTO mechanistic design procedure

There has been a continuous evolutionary process in asphalt pavement design. In the beginning it was crude and based on past experience. Through research, empirical methods were developed based on materials response to specific loading at the AASHO Road Test. Today, pavement design has progressed to a mechanistic-empirical method. This methodology takes into account the mechanical properties of the individual layers and uses empirical relationships to relate them to performance. The mechanical tests that are used as part of this methodology include dynamic modulus and flow number, which have been shown to correlate with field pavement performance. This thesis was based on a portion of a research project being conducted at Michigan Technological University (MTU) for the Wisconsin Department of Transportation (WisDOT). The global scope of this project dealt with the development of a library of values as they pertain to the mechanical properties of the asphalt pavement mixtures paved in Wisconsin. Additionally, a comparison with the current associated pavement design to that of the new AASHTO Design Guide was conducted. This thesis describes the development of the current pavement design methodology as well as the associated tests as part of a literature review. This report also details the materials that were sampled from field operations around the state of Wisconsin and their testing preparation and procedures. Testing was conducted on available round robin and three Wisconsin mixtures and the main results of the research were: The test history of the Superpave SPT (fatigue and permanent deformation dynamic modulus) does not affect the mean response for both dynamic modulus and flow number, but does increase the variability in the test results of the flow number. The method of specimen preparation, compacting to test geometry versus sawing/coring to test geometry, does not statistically appear to affect the intermediate and high temperature dynamic modulus and flow number test results. The 2002 AASHTO Design Guide simulations support the findings of the statistical analyses that the method of specimen preparation did not impact the performance of the HMA as a structural layer as predicted by the Design Guide software. The methodologies for determining the temperature-viscosity relationship as stipulated by Witczak are sensitive to the viscosity test temperatures employed. The increase in asphalt binder content by 0.3% was found to actually increase the dynamic modulus at the intermediate and high test temperature as well as flow number. This result was based the testing that was conducted and was contradictory to previous research and the hypothesis that was put forth for this thesis. This result should be used with caution and requires further review. Based on the limited results presented herein, the asphalt binder grade appears to have a greater impact on performance in the Superpave SPT than aggregate angularity. Dynamic modulus and flow number was shown to increase with traffic level (requiring an increase in aggregate angularity) and with a decrease in air voids and confirm the hypotheses regarding these two factors. Accumulated micro-strain at flow number as opposed to the use of flow number appeared to be a promising measure for comparing the quality of specimens within a specific mixture. At the current time the Design Guide and its associate software needs to be further improved prior to implementation by owner/agencies.
