This research paper is concerned with the need to improve how listening skills are taught in the Capeverdian EFL classroom. Teaching English through listening is not an easy task, especially when there are many factors that impede the learning process such as: lack of adequate materials and conditions; lack of qualified teachers with good pronunciation, and lack of innovative approaches to teaching listening skills. If our goal as teachers is to produce good English speakers we must invest in training good listeners. In this work I will focus on the following aspects: an evaluation of how effectively listening skills are taught in the Capeverdian EFL classroom; a look at how we can turn teaching problems into positive solutions; how to improve teaching listening skills and materials and recommendations for best practices in teaching listening skills in the EFL classroom. In conclusion I will include listening activities which reflect these best practices and offer recommendations for further research.

PURPOSE: The Gastro-Intestinal Working Party of the EORTC Radiation Oncology Group (GIWP-ROG) developed guidelines for target volume definition in neoadjuvant radiation of adenocarcinomas of the gastroesophageal junction (GEJ) and the stomach. METHODS AND MATERIALS: Guidelines about the definition of the clinical target volume (CTV) are based on a systematic literature review of the location and frequency of local recurrences and lymph node involvement in adenocarcinomas of the GEJ and the stomach. Therefore, MEDLINE was searched up to August 2008. Guidelines concerning prescription, planning and treatment delivery are based on a consensus between the members of the GIWP-ROG. RESULTS: In order to support a curative resection of GEJ and gastric cancer, an individualized preoperative treatment volume based on tumour location has to include the primary tumour and the draining regional lymph nodes area. Therefore we recommend to use the 2nd English Edition of the Japanese Classification of Gastric Carcinoma of the Japanese Gastric Cancer Association which developed the concept of assigning tumours of the GEJ and the stomach to anatomically defined sub-sites corresponding respectively to a distinct lymphatic spread pattern. CONCLUSION: The GIWP-ROG defined guidelines for preoperative irradiation of adenocarcinomas of the GEJ and the stomach to reduce variability in the framework of future clinical trials.

1. Aim - Concerns over how global change will influence species distributions, in conjunction with increased emphasis on understanding niche dynamics in evolutionary and community contexts, highlight the growing need for robust methods to quantify niche differences between or within taxa. We propose a statistical framework to describe and compare environmental niches from occurrence and spatial environmental data.¦2. Location - Europe, North America, South America¦3. Methods - The framework applies kernel smoothers to densities of species occurrence in gridded environmental space to calculate metrics of niche overlap and test hypotheses regarding niche conservatism. We use this framework and simulated species with predefined distributions and amounts of niche overlap to evaluate several ordination and species distribution modeling techniques for quantifying niche overlap. We illustrate the approach with data on two well-studied invasive species.¦4. Results - We show that niche overlap can be accurately detected with the framework when variables driving the distributions are known. The method is robust to known and previously undocumented biases related to the dependence of species occurrences on the frequency of environmental conditions that occur across geographic space. The use of a kernel smoother makes the process of moving from geographical space to multivariate environmental space independent of both sampling effort and arbitrary choice of resolution in environmental space. However, the use of ordination and species distribution model techniques for selecting, combining and weighting variables on which niche overlap is calculated provide contrasting results.¦5. Main conclusions - The framework meets the increasing need for robust methods to quantify niche differences. It is appropriate to study niche differences between species, subspecies or intraspecific lineages that differ in their geographical distributions. Alternatively, it can be used to measure the degree to which the environmental niche of a species or intraspecific lineage has changed over time.

Nestling birds produced later in the season are hypothesized to be of poor quality with a low probability of survival and recruitment. In a Spanish population of house martins (Delichon urbica), we first compared reproductive success, immune responses and morphological traits between the first and the second broods. Second, we investigated the effects of an ectoparasite treatment and breeding date on the recapture rate the following year. Due probably to a reverse situation in weather conditions during the experiment, with more rain during rearing of the first brood, nestlings reared during the second brood were in better condition and had stronger immune responses compared with nestlings from the first brood. Contrary to other findings on house martins, we found a similar recapture rate for chicks reared during the first and the second brood. Furthermore, ectoparasitic house martin bugs had no significant effect on the recapture rate. Recaptured birds had similar morphology but higher immunoglobulin levels when nestlings compared with non-recaptured birds. This result implies that a measure of immune function is a better predictor of survival than body condition per se.

We model green markets in which purchasers, either firms orconsumers, have higher willingness-to-pay for lesspolluting goods. The effectiveness of pollution reductionpolicies is examined in a duopoly setting. We show thatduopolists' strategic behaviour may increase pollutionlevels. Maximum emission standards, commonly used in greenmarkets, improve the environmental features of products.Nonetheless, overall pollution levels will rise becausegovernment regulation also affects market shares and bootsfirms' sales. Consequently, social welfare may be reduced.We also explore the effects of technological subsidies andproduct charges, including differentiation of charges.

Desde a última década do séc. XX, o turismo em Cabo Verde tem sido um dos sectores que mais cresce, atraindo maior investimento directo estrangeiro. Contudo, este crescimento gerou também maior pressão sobre os recursos existentes, com impactes negativos a vários níveis. Tem-se reflectido e discutido a sustentabilidade do turismo em território nacional, com objectivos claros de valorização do destino turístico cabo-verdiano, através da conservação e melhoria do ambiente natural, social e cultural. A aposta das autoridades cabo-verdianas no incremento do turismo para o séc. XXI levou a eleição do ecoturismo como a actividade de futuro, com o objectivo de melhorar a competitividade da oferta turística, ser uma alternativa no sector. Uma actividade que pode ser implementada em qualquer ilha, desde que bem aproveitada a vasta oferta de produtos existentes, envolva e forme a população da importância da conservação da biodiversidade e contribua para a erradicação da pobreza ao gerar recursos económicos para as comunidades locais. Deste modo, se requer pensar que arquitectura para o planeamento e realização de infra- estruturas físicas para o adequado desenvolvimento do ecoturismo em Cabo Verde. Os actores directos como os arquitectos, engenheiros civis e planeadores têm uma enorme responsabilidade ao desenhar e executar obras para o turismo, sobre tudo em ecossistemas de grande fragilidade como os que caracterizam as áreas naturais. Sendo um assunto relativamente recente no país, ainda não se criaram normas, regras, directivas claras para o desenvolvimento deste tipo de infra-estruturas turísticas. Em muitos casos, são os próprios desenhadores e construtores, bem como aos seus clientes, quando demonstram alguma sensibilidade na conservação e preservação de áreas de significação ecológica, estabelecem os seus próprios critérios de desenho e códigos éticos que garantam o mínimo de impacte ambiental e uma interacção harmoniosa e sustentável entre a obra física e os espaços circundantes. O presente trabalho tem como objectivo discutir e analisar qual a importância do ecoturismo no panorama arquitectónico cabo-verdiano e se este turismo sustentável será apenas uma ideia teórica, um modelo ideal de actividade ou passível de ser aplicável, de se observar na prática.

Some chronic diseases--like renal failure, liver insufficiency, chronic lung disease, cardiac involvement, diabetes mellitus, asplenia--present limited defects of the immune system and/or a higher risk of infection; therefore, patients with such pathologies should get selective vaccinations. The efficacy of immunization decreases with disease progression; for this reason, these patients should be immunized as soon as possible. At the beginning of their disease, these patients do not need a specialized treatment and are followed by the general practitioner alone who is in charge of immunizing them as well as contact people of any immunocompromised patient. OFSP's regular vaccinations programme is recommended, as well as selective vaccinations against influenza, pneumococci and viral hepatitis, depending on the underlying chronic disease.

This paper describes the influence of high environmental stress on evolutionary trends in some selected Mesozoic ammonite lineages and some protists. During extinction periods, many ammonoids are affected by drastic simplifications of their shell geometry, ornamentation and suture line. We observe that relatively tightly coiled ammonites can give rise to highly evolute forms or uncoiled heteromorphs with simple ornamentation and almost ceratitic suture line-a phenomenon called "proteromorphosis". Such simplifications often correspond to a reappearance of ancestral geometries (primitive ornamentation, evolute coiling or uncoiling) which suggest that the evolutionary clock of these organisms can be reinitialized by extreme, sublethal, environmental stress such as giant volcanism (including its consequences on diverse pollutions and on climatic changes) and major regressive events.

Comparative national management accounting is the least developed aspect in the field of international accounting. Only during the second half of the 1990's some comparisons of national managementaccounting practice have appeared published but only at theregional level. In this paper a range of factors that give rise to variations in national management accounting practice are postulated. We support this list with examples from a range of analyses of national management accounting practices, drawing particularly on the work of Lizcano (1996) and Bhimani (1996).Finally, twelve key factors are identified as influencing an individual country's approach to management accounting.

Faced with recurrent drought and famine during five centuries of human occupation, the small and densely populated Cape Verde Islands have a history of severe environmental problems. The arid climate and steep, rocky terrain provide scant resources for traditional subsistance farming under the best conditions, and in years of low rainfall the failure of rainfed crops causes massive food shortages. Agricultural use of steep slopes where rainfall is highest has led to soil erosion, as has removal of the island's vegetation for fuel and livestock. Pressure on the vegetation is particularly severe in dry years. International aid can provide relief from famine, and the introduction of modern agricultural and conservation techniques can improve the land and increase yield, but it is unlikely that Cape Verde can ever be entirely self -sufficient in food. Ultimately, the solution of Cape Verde's economic and environmental problems will probably require the development of productive urban jobs so the population can shift away from the intensive and destructive use of land for subsistance farming. In the meantime, the people of Cape Verde can best be served by instituting fundamental measures to conserve and restore the land so that it can be used to its fullest potential. The primary environmental problems in Cape Verde today are: 1. Soil degradation. Encouraged by brief but heavy rains and steep slopes, soil erosion is made worse by lack of vegetation. Soils are also low in organic matter due to the practice of completely removing crop plants and natural vegetation for food, fuel or livestock feed. 2. Water shortage. Brief and erratic rainfall in combination with rapid runoff makes surface water scarce and difficult to use. Groundwater supplies can be better developed but capabilities are poorly known and the complex nature of the geological substrate makes estimation difficult. Water is the critical limiting factor to the agricultural capability of the islands. 3. Fuel shortage. Demand for fuel is intense and has resulted in the virtual elimination of native vegetation. Fuelwood supplies are becoming more and more scarce and costly. Development of managed fuelwood plantations and alternate energy sources is required. 4. Inappropriate land use. Much of the land now used for raising crops or livestock is too steep or too arid for these purposes, causing erosion and destruction of vegetation. Improving yield in more appropriate areas and encouraging less damaging uses of the remaining marginal lands can help to alleviate this problem.
