Full textAbstract:
La tesi dottorale “Coesione sociale nell’attualizzazione del Modello Cubano. Studio di caso nel municipio di Trinidad, nella provincia di Sancti Spiritus, Cuba”, è il risultato di una riflessione teorica di tre anni rispetto alla costruzione dei processi sociali e allo sviluppo umano, attraverso un lavoro sul campo multidisciplinare e alla pratica metodologica peculiare del Dottorato in Sviluppo Umano Sostenibile, e si inserisce nel percorso di ricerca del progetto CALSS: ricerca sulla coesione sociale nei consigli popolari, nei quartieri e nelle comunità della provincia di Sancti Spiritus a partire dalle nuove tipologie di imprenditoria e attività socio-produttive, finalizzato ad indagare la costruzione della coesione sociale in relazione alla strategia socialista a livello nazionale.
A partire dal caso di studio si analizza il problema attraverso differenti approcci teorici e da una prospettiva sociologica. L’obiettivo generale consta in un’analisi della coesione sociale a partire dalla descrizione delle forme di interazione sociale che si manifestano in relazione allo sviluppo dell’imprenditoria nel territorio d’analisi, muovendo dalla sfida più ampia del processo di sviluppo che attraversa Cuba.
La ricerca intende offrire una sistematizzazione degli approcci teorici a livello internazionale sulla coesione sociale e una tesi rispetto alle ipotesi che la costituiscono, tenendo in considerazione l’attualizzazione del modello cubano finalizzato alla promozione di una società prospera e solidale, dove possono coesistere diverse forme di gestione economica.La tesis doctoral “Cohesión social en la actualización del Modelo cubano. Estudio de caso en el municipio Trinidad, provincia Sancti Spíritus, Cuba”, es resultado de tres años de debate teórico sobre la construcción de los procesos sociales y el desarrollo humano, de trabajo de campo multidisciplinario y, de prácticas metodológicas propias del Doctorado Internacional en Desarrollo Humano Sostenible, Universidad Milano Bicocca, Italia y el Proyecto “Caracterización de la apropiación que hace la población residente en Sancti Spíritus de la implementación de los Lineamientos, desde la cohesión social, formando parte de los nuevos emprendimientos laborales y socioproductivos en consejos populares, barrios y comunidades” (CALSS) de la Universidad “José Martí Pérez” de Sancti Spíritus, Cuba; con la finalidad de profundizar los supuestos relativos a la construcción de la cohesión social en una estrategia nacional de base socialista. Desde el Estudio de Caso -como estrategia de trabajo metodológica- se analiza la problemática con el propósito de debatir las diferentes visiones teóricas que sobre el tema se discuten en la academia, y contrastar, desde la perspectiva sociológica una experiencia real de cohesión social. Su objetivo general se orienta en el análisis de la cohesión social desde la descripción de las formas de interacción social que se manifiestan con el desarrollo de los emprendimientos en el territorio enunciado, ante el desafío que constituye el proceso de perfeccionamiento que se implementa en Cuba. La investigación aporta una sistematización de enfoques teóricos que predominan a nivel mundial sobre cohesión social y, una argumentación de los supuestos que la constituyen; presentes en la actualización del Modelo cubano y su intención de alcanzar una sociedad próspera y solidaria donde coexisten diferentes formas de gestión económica. A partir de la triangulación metodológica para la comprensión de las formas de interacción de los sujetos sociales se enfatiza en una perspectiva renovadora de los supuestos de la cohesión social, dígase, grupo de recomendaciones genéricas que enriquecen sus dimensiones; desde ahí el papel de los individuos como agentes de transformación social.

Full textAbstract:
As the only developed country with a mostly publicly-owned and centrally-planned economy, sociological study of Cuba offers profound opportunities for theoretical and practical consideration of the viability of that model. Hitherto unseen levels of support for socialism among Americans and a renewed European Left in the wake of the Great Recession and worsening human-caused climate change provide a context of renewed interest. Cuba’s geographic location, high standard of living, ethnic/racial diversity, and relative cultural liberalism, further, make it the uniquely best-suited counterexample to the “end of history” model of (neo)liberal democratic consensus. While limited, partial analyses of the Cuban system abound, attempts to synthesize this information and meaningfully address its unique development of the Marxist-Leninist single-party state as a legitimate form of society are nearly nonexistent. I will argue that the system’s survival and significant adaptations from its past as a Soviet client state warrant a second look as a viable alternative type of social organization. A review and synthesis of the social scientific literature in addition to notions of democracy and attempts to quantify utilitarian function like Happy Planet Index demonstrates that, more so than untested models, the Cuban one presents a viable if very imperfect example of equitable sustainability.

The Anode effect that occurs in electrolytic smelter pot is responsible for gases such as PFC s. These gases contribute to the greenhouse effect, and in addition jeopardizes its productive capacity. From the voltage (output) and current (input) are estimate ARX and OE models of the electrolytic smelter pot using the Systems Identification Theory, the ARX and OE models of the electrolytic smelter pot are built to represent the steady state operation and the anode effect occurrence. After the simulation are chosen the models with better adjustment to the measure exit. For the selection are used established criteria along the research, the ARX and OE models of electrolytic smelter pot, are built to represent the full state operation of the electrolytic smelter pot. Based on real data and via algebraic properties, the models generate the functions of specific transfer of each model that are validated with real data obtained in the industry, the answer in time, in the convergence frequency and speed are analyzed. From the transfer function is made the representation of the normal stage of operation of the electrolytic smelter pot, and by the properties of the estimate model is made the prediction the anode effect identifying the increase of the voltage in the validation stage. Therefore, this work introduces the investigation of ARX and OE parametric models how better represent the operation of the electrolytic smelter pot to can enable the prediction of the anode effect in the productive process of the aluminum. In this dissertation, we propose the models development in the domain of the continuous and discreet time with a study of her transitory answers and of steady state as well as your answer in frequency of your normal operation and in the phase that precedes the anode effect.
O efeito anódico que ocorre nas cubas eletrolíticas é responsável pela emissão de gases como os PFC s, gases esses, que contribuem para o efeito estufa, além de comprometer sua capacidade produtiva. A partir dos sinais de tensão (saída) e corrente (entrada) são estimados modelos ARX e OE da cuba eletrolítica utilizando a Teoria de Identificação de Sistemas. Após a simulação são escolhidos os modelos com melhor ajuste à saída medida. Para a seleção são utilizados critérios estabelecidos ao longo da pesquisa. Os modelos ARX e OE das cubas eletrolítica, são construídos para representar o pleno estado de funcionamento da cuba. Baseados em dados reais e via propriedades algébricas, os modelos geram as funções de transferência específicas de cada modelo que são validadas com dados reais obtidos na indústria, a resposta no tempo, na freqüência e velocidade de convergência são analisadas. A partir da função de transferência é feita a representação da fase normal de funcionamento da cuba eletrolítica, e pelas propriedades do modelo é feita a predição do efeito anódico identificando o aumento da tensão na fase de validação. Portanto, este trabalho apresenta a investigação de modelos paramétricos ARX e OE que melhor representam o funcionamento da cuba eletrolítica para possibilitar a predição do efeito anódico no processo produtivo do alumínio. Nesta dissertação propomos o desenvolvimento de modelos no domínio do tempo contínuo e discreto com um estudo das suas respostas transitória e de regime permanente assim como sua resposta em freqüência de seu funcionamento normal e na fase que antecede o efeito anódico.

Full textAbstract:
In this dissertation, the socio-ecological transformations that occurred during Cuba’s Revolución Agrícola are explored, against the backdrop of the historical subalternisation of the country as a consequence of Spanish and American imperialism, and in relation to the continuing subalternisation of the country and its people through the neoliberal mass media. To contextualize such exploration, the origins of large-scale privatization of common land, and the subsequent process of urbanization in the West, are investigated, before Cuba’s similar developmental path – as a result of Spanish colonialism, U.S. imperialism, and communist influence – is detailed. Thereafter, the way in which Cuba established an alternative food paradigm, characterised by local, communal, and urban production during the country’s ‘Special Period’ in the 1990s, is discussed, with a view to illustrating how this eco-socialist model of food production, in both rural and urban areas, led to new relations between people and nature. This Cuban model is then posited as a socio-ecologically sustainable model of food production, deserving of the attention of communities around the world, who seek to gain a degree of autonomy from neoliberal agribusiness. Conversely, the efforts of mainstream neoliberal mass media to silence the immensely positive characteristics of the revolution are also investigated, and framed in terms of the historical subjugation of Cuban voices in the American mass media, and the contemporary marginalisation of the country and its people in the neoliberal mass media. Finally, the dissertation concludes by examining the alternative media response, on the part of several prominent Cubans and those sympathetic to their cause, to bring attention to the value of the socio-ecological transformations that have occurred on the island, against the backdrop of various theorisations of the importance of alternative media platforms as a radical counterforce to neoliberal mass media hegemony.

Full textAbstract:
The current study investigated vowel quality in Miami Cuban Spanish, looking specifically at the influence of English on the Spanish vowel system. The vowel production of eleven Miami Cubans from three generations is investigated. Subjects include six males and five females. Three different elicitation instruments were used. The first was a brief sociolinguistic interview, the second was a story that the participants were asked to read aloud. Carrier words were embedded into the story in order to obtain multiple samples of both stressed and unstressed vowels. For the third instrument, subjects were asked to read a list of words with careful attention to their pronunciation. The reading list contained the same words that were embedded in the story of the first task. These three instruments were repeated in both Spanish and in English in order to investigate possible English influence in the Spanish vowel system of these bilinguals.

Full textAbstract:
The present study consisted of two parts: (1) The examination of whether demographic differences in utilization of multiple forms of health services existed among Non-Hispanic Whites, Mexican-, Cuban-, and Puerto Rican-American adolescents. (2) The examination of whether the Andersen model, revised for Latino adolescents, fit equally well for Mexican-, Cuban-, and Puerto Rican-Americans. Data for this study were drawn from the first two waves of the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative sample of 7th through 12th-grade students in the United States collected between 1994 and 1996.Logistic regression analyses indicated that there were significant differences in routine physical exams based on ethnicity. Mexican-American adolescents were less likely than Non-Hispanic White, Cuban-American, and Puerto Rican-American adolescents to receive routine physical exams. Finding based both on the logistic regressions and on the latent mean comparisons suggested that Cuban- and Puerto Rican-American adolescents are more likely to utilize health services than Mexican-American adolescents. Cuban-American adolescents were also less likely to indicate the need for medical services, whereas Mexican-American adolescents were more likely to state that they needed medical services but were unable to receive them.The results of multi-group confirmatory factor analyses provide mixed evidence toward the indication that the revised Andersen's conceptual model is an appropriate overall framework to utilize with Mexican-, Cuban-, and Puerto Rican-American adolescents. Based on the structural equation model findings, it appears that the major link between need and use of health care services is not supported in the three Latino subgroups. The Andersen model only partially addressed health care needs among the adolescent Latino subgroups. Although there are connections from the main predisposing predictors (including Latino adolescent-specific characteristics) to enabling resources and need, these indirect associations do not necessarily predict use of health services with Mexican-, Cuban-, and Puerto Rican-American adolescents. Clearly there is a great need for health care services among Latino adolescents, particularly given their health disparities in adolescent risk behavior; however current models need further revision, such as including key cultural factors and social context, to predict use of health care services.

Full textAbstract:
Since the Soviet collapse in 1991, Cuba tried intensively to attract foreign direct investments in order to improve the economic situation. The first reform was made in 1995, which was not a success, since both foreign direct investment and joint ventures decreased in the beginning of the 21st Century. In response, the government implemented a new law concerning foreign direct investment in 2014, with more relaxed regulations and increased benefits for the investors. This study aimed to examine whether the 2014 reform had solved the problems that existed under the previous law and the new reforms had helped Cuba’s exports. The purpose was therefore to investigate to which industry foreign direct investment should be allocated. The study took two approaches. First, it applied the Revealed Comparative Advantage model to distinguish effective from ineffective industries. It included a field study that aimed to gain understanding of the effect the new law has had so far, and whether it could improve exports. In addition, the field study attempted to determine where foreign direct investment should be allocated. The results indicated that Cuba has a comparative advantage in two industries: mining and agriculture. These industries were therefore examined in the field study. Key findings showed that ongoing issues, such as bureaucracy, lack of legal security and the wage policies of government employment agencies still exist, despite the introduction of new legislation. However, the new law may create increasing export possibilities in the food and mining industries, since Cuba has an outwardly-orientated policy and large factor proportions in agriculture and mining that could be exploited.Minor Field Study (MFS)

Full textAbstract:
This cross sectional study investigated the association between 25-hydroxyvitamin D (25(OH)D) levels, vitamin D receptor (VDR) polymorphisms, HOMA2 and diabetes status in Cuban Americans, Haitian Americans, and African Americans. The sample for the study included a total of 885 participants (Cuban American = 370; Haitian American = 259; African American = 256). Serum 25(OH)D levels were determined using a commercial ELISA kit from Immunodiagnostic Systems Limited. Polymerase chain reaction-restriction fragment length polymorphism (PCR- RFLP) was used for genotyping BsmI and TaqI, Real-time- Polymerase chain reaction (RT-PCR) was used for ApaI. HOMA2 model calculations were used as a surrogate marker for insulin resistance, insulin sensitivity and β-cell function. All statistical analyses were performed using SPSS (Version 18.0, Chicago, IL, U.S.). Student’s t-test and analysis of variance (ANOVA), c2 test and logistic regression analysis were used.
We found that Cuban Americans without T2D had significantly lower odds of having insufficient 25(OH)D compared to all other groups. Participants with darker skin (Haitian Americans and African Americans) and those with T2D had the greatest risk of having insufficient levels of 25(OH)D. Cuban Americans with T2D had a protective factor for vitamin D insufficiency if they carried the TaqI genotype (tt) (p < 0.02) and Cuban Americans without T2D had the highest β-cell function levels (p < 0.05).
Further investigation is needed to have a better understanding of the role vitamin D, VDR polymorphisms and the role HOMA2 model plays in the three ethnicities. Awareness of the high prevalence of vitamin D insufficiency among Haitian Americans and African Americans and also in those with T2D may sensitize physicians and dietitians to increase efforts to prevent vitamin D insufficiency. Further research to investigate the role and mechanism of action of vitamin D and diabetes is warranted.

Full textAbstract:
Fondée sur onze mois d’enquête de terrain à Cuba, cette thèse a un objectif double : comprendre comment des dynamiques contestataires émergent et perdurent sur le long terme sans faire l’objet d’une répression sévère, à l’instar des dissidents ; et saisir ce que l’existence de cette contestation tolérée nous apprend sur les modes d’exercice du pouvoir dans un tel contexte. Les pratiques contestataires sont ici problématisées comme intentionnelles, collectives et conflictuelles et étudiées de façon relationnelle, afin de restituer les logiques d’interaction entre autorités socialistes et collectifs contestataires. A partir de cette démarche, ce travail montre que les pratiques contestataires sont partiellement tolérées par les autorités car elles ne sont ni ppositionnelles ni directement politiques. Elles s’articulent, quoique de façon critique et parfois subversive, aux normes de la socialisation révolutionnaire, qui fondent les cadres légitimes de perception de la réalité. Elles s’inscrivent aux marges du champ culturel à travers l’élaboration d’un répertoire hybride, entre action collective et création culturelle. Ces ambiguïtés permettent aux collectifs de négocier des espaces d’action selon les échelles de gouvernement. Les autorités leur octroient ces espaces car ils permettent la régulation et la contention de la contestation, à travers une coercition fondée sur l’incertitude et l’arbitraire. Cette étude met ainsi à jour la plasticité du régime cubain et incite, au-delà de ce cas spécifique, à substituer aux analyses en termes d’érosion de la capacité à gouverner l’observation des modes d’adaptation et de transformation des régimes autoritairesThis dissertation is based on eleven months of fieldwork in Cuba. Its objective is twofold. First, understand how contentious dynamics have emerged and endured through time without undergoing severe repression, like dissident movements. Secondly, grasp what the existence of this tolerated contention tells us about the way power is wielded in such a context. Contentious practices are here defined as intentional, collective and conflictive. This study focuses on the relationships between contentious movements and State authorities, in order to understand the logics of their interactions. Elaborating on this, this dissertation shows that contentious practices are partly tolerated by the authorities because they are neither oppositional nor directly political. They are linked up, though in a critical and sometimes subversive way, to the norms of the revolutionary socialization, on which are based the legitimate frameworks for perception of reality. Contentious movements are situated at the margins of the cultural field, thanks to the creation of a hybrid repertoire: between collective action and cultural creation. That ambiguity allows them to negotiate space for action, according to the levels of government. Authorities grant them some space because that this allows for the regulation and containment of contention, through the use of a specific mode of coercion, which is based on uncertainty and arbitrariness. This study also brings to light the plasticity of the Cuban regime and invites us, beyond that specific case, to substitute analyses in terms of erosion of governing capacity for analyses of the modes of adaptation and transformation of authoritarian regimes

Apesar de consideráveis avanços na análise de impacto e gestão de riscos de movimentos de massa, estes continuam a representar grande risco à vida e infraestruturas em regiões montanhosas no mundo. A região da Serra do Mar, devido à suas características geomorfológicas, climáticas e ao avanço da urbanização, é região favorável à ocorrência de movimentos de massa, sobretudo os escorregamentos translacionais rasos. Embora a previsão de áreas instáveis seja essencial para a redução dos danos que esses processos causam, a tarefa não é simples em função da complexidade e variabilidade de fatores que controlam a estabilidade das encostas. A aplicação de modelos de bases físicas é forma objetiva de caracterização de movimentos de massa, especialmente escorregamentos translacionais, em função da aplicação direta de equações que descrevem fisicamente esses processos erosivos naturais, prevendo a suscetibilidade sob diferentes cenários de uso e ocupação do solo e situações climáticas. Este trabalho tem como objetivo a avaliação da suscetibilidade a escorregamentos translacionais rasos nas bacias hidrográficas dos rio Mogi e Perequê, município de Cubatão (SP), através da caracterização geológica-geotécnica e da aplicação dos modelos de base física SHALSTAB e SINMAP. Ademais, tem como objetivo a determinação do modelo que melhor se aplica à região de estudo nas escalas de trabalho. Através da criação do modelo digital de elevação (MDE) da área de estudo, base para a obtenção das informações topográficas, da coleta de amostras de solo nas campanhas de campo e da realização de ensaios laboratoriais na obtenção dos parâmetros geotécnicos, é feita a modelagem usando os modelos SINMAP e SHALSTAB nas escalas de 1:50.000 e 1:10.000. A calibração dos modelos é baseada no mapeamento de cicatrizes de episódios de escorregamentos que ocorreram na região nos anos de 1994 e 1985, onde, respectivamente, 542 e 1679 cicatrizes foram mapeadas por meio de imagens aéreas na escala de 1:25.000. Utilizando os métodos de taxa de sucesso e erro e matriz de contingência na determinação do modelo que melhor se aplica à área de estudo, o modelo SHALSTAB mostra-se o mais adequado em ambas as escalas de trabalho pois apresenta maior acurácia (cicatrizes dentro de áreas instáveis) e menor proporção de cicatrizes em áreas estáveis (falsos negativos). Portanto, o emprego de modelos de bases físicas na avaliação da suscetibilidade a escorregamentos na Serra do Mar mostra-se eficaz e representa importante auxílio na análise de risco que esses fenômenos podem representar à sociedade. A determinação do modelo que melhor se aplica a uma área específica é essencial na qualidade e eficiência de análises e avaliações de riscos a escorregamentos pois é uma ferramenta direta e objetiva de representação de processos erosivos.
Despite considerable advances on mass movements risk analysis and assessment, these processes still represent great danger to infrastructure and human lives in mountainous regions around the world. The Serra do Mar region, due to its geomorphological and climatic characteristics and due to urbanisation increase, is highly susceptible to mass movements’ occurrences, especially shallow landslides. While the prediction and mapping of unstable areas are essential to mitigate damages that these processes can cause, it is not an easy task due to the complexity and variability of the parameters that control slope stability. The application of physically based models is an objective method to characterise mass movements, especially shallow landslides, since it directly applies equations that physically describe the processes, predicting their susceptibility under many different scenarios of land use and climatic situations. The objective of this dissertation is the application of the SHALSTAB and SINMAP models on shallow landslide susceptibility assessment at the Mogi and Perequê rivers’ watersheds, in the municipality of Cubatão (São Paulo). Also, it aims to determine which model best represents slope stability in the study area at each work scale. Based on the digital elevation model (DEM), which provides topographic information to the model, and soil samples collected during fieldwork that later were tested to acquire geotechnical parameters, the modelling of shallow landslides is made using the SINMAP and SHALSTAB models at the scales of 1:50.000 and 1:10.000. The model calibration is based on landslide scars mapping of mass movements events that occurred in the region in 1994 and 1985, where, respectively, 542 and 1679 landslides scars were mapped using aerial images at a scale of 1:25.000. By using the success and error index method and a contingency table to determine the model that best suits the study region, the SHALSTAB model stands out as the most adequate in both work scales since it presents a higher accuracy (landslide scars within unstable areas) and lower proportion of landslide scars in stable areas (false negatives). The application of physically based models in assessing landslide susceptibility at the Serra do Mar region proves to be successful and, therefore, represents an important tool in risk analysis and assessment. The determination of a model that best represents the slope stability of a particular region is essential to the quality and efficiency of landslide risk analysis and assessment, as well as in urban planning, since it is a direct and objective method of representing and predicting the occurrence of these erosive processes.

Full textAbstract:
The aim of this study is to describe two strategies of professional teacher development in Cuba and analyse how they affect the professional growth of the teachers. The strategies investigated are methodological work sessions and further education at the university. Eight upper-secondary school teachers were interviewed and it was analysed how their professional growth was affected by the Cuban professional development strategies. The model utilized was the interconnected model of professional growth (Clarke & Hollingsworth, 2002).The results show that, four of the eight interviewed teachers experienced change sequences and growth networks as a consequence of participating in the two investigated strategies. The methodological work sessions promote a collaborative approach among the teachers to developing the education in their school. Further education in the university, on the other hand, encourages the teachers to reflect individually on practical school-related problems. The results indicate that the organization of the work both the professional development strategies provided acted as an incentive for the interviewed teachers’ development.Målet med den här studien är att beskriva två lärarutvecklingsstrategier i Kuba och analysera hur de påverkar lärarnas professionella utveckling. De undersökta strategierna är metodologiska arbetsmöten och vidareutbildning vid universitet.

Modellen som använts är the interconnected model of professional growth (Clarke & Hollingsworth, 2002).Resultaten visar att de metodologiska arbetsmötena uppmuntrar lärarna att arbeta kollektivt med att utveckla utbildningen i sin skola. Universitetsvidareutbildning, vad andra sidan, främjar individuell reflektion över praktiska skolrelaterade problem. Resultatet indikerar att den organisation av arbetet som båda lärarutvecklingsstrategierna medför stimulerar lärarna att utvecklas.

A presente tese apresenta uma proposta de construção de um modelo multicritério utilizando uma abordagem construtivista, para avaliar potenciais candidatos a receber a outorga de uso da água. A ocupação territorial desordenada, e a concentração da população nos centros urbanos, somada ao aumento da demanda regionalizada de água, tornam a cada dia os conflitos pelo uso da água mais complexos, exigindo medidas nem sempre simples para sua resolução. As soluções nesse campo necessitam de abordagens abrangentes, incluindo aspectos legais, técnicos, sociais, econômicos e ambientais. O processo de outorga é um instrumento de gestão dos recursos hídricos que visa à racionalização do seu uso. Para a implantação da outorga se faz necessário definir critérios e estabelecer um mecanismo ou adotar ferramentas que permitam a transparência do processo, de maneira a não suscitar conflitos entre os distintos usuários. Métodos utilizados na pesquisa operacional tradicional, como a programação linear, consideram como melhor alternativa aquela que otimiza uma determinada função, a qual avalia a performance das alternativas segundo o critério considerado. A metodologia Multicritério de Apoio à Decisão (MCDA), por sua vez, incorpora múltiplos aspectos, tanto objetivos como subjetivos, considerados importantes pelos tomadores de decisão. Para o desenvolvimento desta pesquisa foi realizado um estudo de caso da bacia hidrográfica do rio Cubatão do Sul, considerando-se como tomadores de decisão um sub-grupo do conjunto de membros do comitê da referida bacia, que possui uma área de 738 km2 e fornece água para o abastecimento de aproximadamente 800 mil habitantes em cinco municípios. Como resultado da pesquisa, foi desenvolvido um modelo para avaliação de potenciais candidatos à outorga da água. A utilização da metodologia MCDA foi essencial para a negociação e entendimento do processo de outorga dos recursos hídricos pelos tomadores de decisão. O modelo construído pode dar suporte à tomada de decisão pelo poder público em relação às solicitações de outorga de uso da água da bacia.

La tesi es centra en una anàlisi prèvia de les implicacions de la teoria del cicle de vida aplicada a les destinacions turístiques pel geògraf canadenc Richard W. Butler (1982) i en un estudi del significat de l'aparició del postmodernisme i les seves repercussions en el turisme, a la vegada que es resegueix la història que ha fet possible l'aparició del turisme massificat de sol i platja.Tot això és la base teòrica imprescindible per poder estudiar empíricament les destinacions de Saltburn (Regne Unit), l'Estartit (Costa Brava) i Cayo Coco (Cuba), utilitzant el cicle de vida per escriure la seva història i veure les polítiques de desenvolupament i regeneració turística que s'han seguit i si aquestes es poden qualificar de postfordistes. La principal conclusió és que el concepte del cicle de vida es limita a ser una eina de diagnòstic a posteriori. El cicle de vida, com a instrument prescriptiu, no serveix. Es específic per a cada destinació, amb unes etapes i punts d'inflexió que només es poden establir en restrospectiva. El cicle de vida és una eina descriptiva molt útil per entendre l'evolució de les destinacions turístiques i els seus mercats, però vigilant de no caure en falses exploracions o perillosos determinismes.
This thesis is based on an analysis of the implications of the life-cycle theory on tourist destinations by the Canadian geographer Richard W. Butler (1982); and on a study of what the emergence of postmodernim and its repercussions on tourism have meant. At the same time, the history that has made the appearance of mass sun and beach tourism possible is reviewed.
All this is the theoretical basis for the empirical study of the tourist destinations of Saltburn (United Kingdom), l'Estartit (Costa Brava) and Cayo Coco (Cuba). Life cycle is used as the instrument for writing their history and seeing what development and tourist regeneration policies they have followed and whether they can be defined as post-Fordist policies.
In conclusion, current tourist models, more inauthentic, diverse and customised, place a question-mark over the Fordist tourist practices of previous decades, although there are still more elements of continuity than of change. The idea now is to make the Fordist tourist model feasible, by using postmodernism as an instrument to give a theoretical and ideological gloss to the model that can be still called Fordist, but that has been adapted to new times and settings.

Previous issue date: 2011Atualmente as empresas necessitam de sistemas que lhes dêem um suporte na tomada de decisões, o que pode ser crucial para a sobrevivência da empresa no mercado econômico global. Os sistemas transacionais possuem limitações em relação a isto. Portanto, é necessário o desenvolvimento de um sistema de Data Warehouse associado à utilização de ferramentas OLAP, que suprem as limitações dos sistemas tradicionais. Considerando as particularidades deste tipo de sistemas, as técnicas utilizadas na modelagem de dados para sistemas tradicionais, não possuem a mesma eficácia para estes sistemas de Data Warehouse. A Modelagem Multidimensional é a que melhor traz benefícios para este tipo de ambiente, pois consegue representar de forma fidedigna a realidade dos negócios. Paralelo a isto, a Web Semântica surge para transformar a Web de um repositório de documentos interligados em uma base de conhecimentos distribuídos. Sua idéia central é tornar o significado da Web acessível e processável pelas máquinas. Ela engloba uma combinação das seguintes tecnologias: Metadados, Ontologias e Inferências Lógicas. Uma Ontologia é um modelo de dados que representa um conjunto de conceitos de um determinado domínio e os relacionamentos entre estes. Ela serve então para descrever formalmente um domínio do discurso, seus indivíduos, classes, atributos e relacionamentos. Este trabalho traz uma proposta de geração semi-automatizada de modelos multidimensionais de cubos OLAP a partir de ontologias. Para tanto, são abordados os principais conceitos de um sistema de Data Warehouse, e da modelagem multidimensional. Também são tratados alguns conceitos da Web Semântica e de Ontologias. Após isto são analisados alguns trabalhos que utilizam a web semântica na modelagem de sistemas de Data Warehouse. Um protótipo foi desenvolvido como prova de conceito. Por fim são apresentadas as conclusões e sugestões de trabalhos futuros dentro da área de estudo

Previous issue date: 2008-05-21The purpose of this study is to investigate how the authoral division is processed in the romance Memórias Póstumas de Brás Cubas and what it represents to the realistic-cienficist literary patterns of the XIX century. Having as a central focus the questioning about the authorial signature, the critical analysis concentrated itself in the strategies of this authorial dissemination through three basic principles: the duplicity of the opening prologues between Brás Cubas supposed author and Machado de Assis the authorial signature inscribed in the book; the fiction of the dead author and the conception of autobiography as a portrait of the real author, questioning the frontiers between the fictional and empirical author; the truncated citations and the continuous dislocations of the supposed author Brás Cubas to the function of reader of his own book, which turns the reader into an author, promoting a corrosion of the authorial unity. As a conclusion, the study demonstrated that the questioning of the authorial signature in Memórias Póstumas was an instabilizing element of the romance standard in the realism-naturalism of the XIX century, also affecting the criticism of the sources by means of the authorial reading fiction responsible for the gnawing citations of an author-reader that speaks to us from the other side of the mistery
A proposta deste estudo é investigar como a divisão autoral é processada no romance Memórias Póstumas de Brás Cubas e qual sua representação para o cientificismo-realista literário do século XIX. Apresenta como foco central o questionamento sobre a paternidade autora. A análise crítica se concentrou nas estratégias dessa disseminação autoral por meio de três princípios básicos: a duplicidade dos prólogos de abertura entre Brás Cubas autor suposto - e Machado de Assis - a assinatura autoral inscrita no livro; a ficção do autor morto e a concepção de autobiografia como retrato do autor real, colocando em questão as fronteiras entre autor ficcional e empírico; as citações truncadas e os contínuos deslocamentos do autor suposto Brás Cubas - para a função de leitor do próprio livro que escreve, o que faz do leitor autor, promovendo a corrosão da unicidade autoral. Como conclusão, o estudo demonstrou que o questionamento da paternidade autoral em Memórias Póstumas foi um elemento desestabilizador do modelo de romance do realismo-naturalismo do século XIX, bem como abalou os pressupostos da crítica de fontes por meio da ficção de leitura autoral responsável por citações roídas de um autor-leitor que nos fala do outro lado do mistério

Esta dissertação faz uma investigação sobre a relação entre identidade europeia e integração regional. Desta forma, analisam-se quais elementos, durante o processo de construção de uma comunidade europeia integrada e cooperativa, contribuíram para a constituição de uma identidade compartilhada. Tendo-se admitido a existência de uma identidade europeia fundada nas dimensões cívico-institucional, histórico-cultural e nacional, este trabalho propõe uma análise tridimensional das percepções identitárias nacionais dos Estados membros da União Europeia e um modelo de distribuição espacial. A hipótese central do estudo é a de que a integração europeia, principalmente por meio de suas instituições, como é analisado no estudo comparativo dos países que adotaram o Euro, afeta a mudança nas identidades dos cidadãos e seu senso de pertencimento a essa comunidade supranacional. O estudo da questão identitária, a avaliação do sentimento de pertencimento a um ethos europeu e a delimitação das fronteiras dessa identidade europeia são essenciais para entender os rumos do processo de integração no que se refere ao maior aprofundamento e ao maior alargamento do bloco. _______________________________________________________________________________________________ ABSTRACT
This dissertation presents a research on the relationship between European identity and regional integration. Thus, analyses which elements, during the process of building an integrated and cooperative European community, contributed to the constitution of a shared identity. Considering the existence of a European identity based on civic-institutional, historic-cultural and national dimensions, this dissertation proposes a three-dimensional analysis of the European Union Member States’ national identity perceptions. The central hypothesis of this research is that the European integration, particularly through its institutions, as analysed on the comparative study of countries that have adopted the Euro, affects the change in the identities of people and their sense of belonging to this supranational community. The study of the identity, the evaluation of the feeling of belonging to a European ethos and the demarcation of the boundaries of this European identity are essential to understand the direction of the integration process with regard to the further deepening and enlargement of the bloc.

Este estudo foi elaborado com o objetivo de colher subsídios de coordenadores de estágio, ou de cursos de Administração de Empresas, sobre a problemática do estágio supervisionado de estudantes. Com o recurso de questionário e de entrevista semi-estruturada, levantaram-se dados específicos sobre políticas e práticas de estágio vigentes numa amostra intencional de onze instituições de ensino superior localizadas na mesorregião Metropolitana de Curitiba. O Cubo de Dificuldade, que pretende conciliar a pedagogia do ensino-aprendizagem e a pedagogia do trabalho, foi adotado como modelo referencial para provocar a análise, reflexão e crítica do grupo de entrevistados. Para contextualizar a pesquisa, de caráter exploratório, foi feita uma caracterização do estágio e de seus possíveis benefícios para as partes envolvidas: estudante, escola e empresa. Examinaram-se os principais elementos da legislação de estágio, bem como as diretrizes curriculares que norteiam o curso de Administração de Empresas. O estágio de estudantes, entendido como treinamento de papel profissional, foi descrito ao longo de três dimensões de natureza sistêmica: operacional, conceitual e situacional. De acordo com os resultados da pesquisa, detectou-se que as instituições de ensino consultadas dedicam pouca atenção aos estágios não-obrigatórios e, em relação aos de caráter obrigatório, prevalece uma concepção formalística do processo com baixo grau de interação com os campos de aplicação. O conjunto de enunciados que fundamenta o Cubo de Dificuldade foi avaliado, em termos gerais, de forma positiva pelos entrevistados.

The objective of this study was to propose models that aid decision making in productive process of Pinus caribaea var. caribaea Barr. & Golf. through the application of multivariate techniques, regression analysis, multicriteria decision analysis techniques (MCDA) and Artificial Neural Networks (ANNs) in different stages of said process. The three stages of the forest production process (PPF) involved in the present study were: (1) growth, yield and forest survival stage; (2) wood extraction and transport stage, and (3) wood primary transformation stage. Pinus caribaea var. caribaea growth, yield and survival modeling required data from temporary and permanent circular plots of 500 m² of the Macurije Integral Forest Company, in which the following variables were measured: : Diameter at Breast Height - DBH (cm), total height - H (m) and survival - (num. of trees/ha). At this stage, the specie productive capacity classification was carried, Artificial Neural Networks (ANNs) were trained and regression models were adjusted for growth prediction and yield and survival prognosis. At wood extraction and transport stage, the performance of different wood extraction systems and means was evaluated through univariate and multivariate factorial experiments, being cost and productivity the dependent variables obtained by time and movement studies. At the same stage, a Lexicographic Goals Programming model was proposed to assist decision making in harvesting and forest transport planning. At the stage of wood primary transformation in Combate de Tenerías sawmill, regression models were adjusted and ANNs were trained, both for lumber recovery factor prediction and lumber classification. Lumber quality being a discrete ordinal variable, ordinal logistic regression was used for its modeling. The database required for lumber recovery factor modeling was composed by the variables Diameter at Breast Height (DBH), Smallest log diameter (D) and conicity (Con.) obtained from real-time monitoring of wood sawing at the sawmill Combate de Tenerías. The 24 variables predicting lumber quality were measured in pieces obtained at the end the end of sawing process in the same sawmill. The results obtained during the research indicated that multivariate, multicriteria and Artificial Neural Networks techniques are efficient in assisting decision-making in FPP stages considered. ANNs models presented similar or superior performances to the traditional regression models both in prediction (volumetric growth, lumber recovery factor) or prognosis (survival, growth and yield) and in lumber grading. From the results, it was concluded that it is not prudent to assume absolute superiority of ANNs and that opting for the complementarity of both approaches rather than the exclusive use of ANNs, as most comparative research tends to suggest, is far more prudent. Multivariate evaluation of wood extraction machineries performances and the Lexicographic Goal Programming model proposed for timber extraction and transport planning provided a multicriteria support translated into solutions with greater practicality and functionality.
Objetivou-se no presente estudo, propor modelos que auxiliem na tomada de decisões no processo produtivo de Pinus caribaea var. caribaea Barr. & Golf. por meio da aplicação de técnicas multivariadas, análise de regressão, técnicas de análise de decisão multicritério (MCDA) e Redes Neurais Artificiais (RNAs) em diferentes etapas do referido processo. As três etapas do processo produtivo florestal (PPF) envolvidas no presente estudo foram: (1) a fase de crescimento, produção e sobrevivência florestal; (2) a fase de extração e transporte florestal e (3) a fase de transformação primária da madeira. A modelagem de crescimento, produção e sobrevivência da espécie requereu de dados provenientes de parcelas temporárias e permanentes circulares de 500 m² de plantios de Pinus caribaea var. caribaea da Empresa Florestal Integral Macurije, nas quais foram medidas as variáveis: Diâmetro à Altura de Peito DAP (cm), altura total – H (m) e sobrevivência - (árv./ha). Nessa etapa, foi realizada a classificação da capacidade produtiva da espécie, foram treinadas Redes Neurais Artificiais (RNAs) e foram ajustados modelos de regressão para a predição e prognose de sobrevivência e crescimento e produção florestal. Na etapa de extração e transporte florestal, avaliou-se o desempenho de diferentes meios e sistemas de extração de madeira por meio de experimentos fatoriais univariados e multivariados sendo custo e produtividade as variáveis dependentes obtidas por estudos de tempo e movimento. Na mesma etapa, se propôs um modelo de programação por metas lexicográficas para auxiliar a tomada de decisão na extração e transporte florestal. Na etapa de transformação primária da madeira na serraria Combate de Tenerías, foram ajustados modelos de regressão e foram treinadas RNAs, tanto para a predição do rendimento em madeira serrada como para a classificação da mesma. A qualidade de madeira serrada sendo uma variável discreta ordinal, a regressão logística ordinal foi utilizada para sua modelagem. A base de dados requerida para a modelagem do rendimento em madeira serrada foi composta pelas variáveis Diâmetro a Altura do Peito (DAP), Diâmetro menor da tora (D) e conicidade (Con.) obtidas do acompanhamento em tempo real do desdobro da madeira na serraria Combate de Tenerías. As 24 variáveis preditoras da qualidade de madeira serrada foram mensuradas em peças obtidas ao final do processo de desdobro na mesma serraria. Os resultados obtidos ao longo da pesquisa indicaram que as técnicas multivariadas, multicritérios e as Redes Neurais Artificiais são eficientes no auxílio à tomada de decisão nas etapas do PPF consideradas. Os modelos de RNAs apresentaram desempenhos similares ou superiores aos modelos tradicionais de regressão tanto na predição (crescimento volumétrico; rendimento em madeira serrada) ou prognose (sobrevivência; crescimento e produção florestal) como na classificação da madeira serrada. Através dos resultados obtidos ao longo da pesquisa, concluiu-se que não é prudente assumir a superioridade absoluta das RNAs e que optar pela complementaridade de ambas as abordagens em vez do uso exclusivo das RNAs, como a maioria das pesquisas comparativas tendem a sugerir, é bem mais argucioso. A avaliação multivariada dos desempenhos dos meios de extração de madeira e o modelo de programação por metas lexicográfica proposto para o planejamento de extração e transporte de madeira proporcionaram um apoio multicritério traduzido em soluções com maior praticidade e funcionalidade.

Resumo: Modelos matemáticos de predição de erosão e produção de sedimentos tem um grande potencial para uso em estudos da degradação e manejo dos recursos naturais, pois permitem estimar os impactos causados pela atividade agrícola. Este trabalho trata da aplicação do modelo hidrológico SWAT (Soil Water Assessment Tool), com a finalidade de previsão dos riscos de erosão devido às mudanças no uso da terra, na bacia do rio Chambas na província Ciego de Ávila, em Cuba. Este modelo tem sido utilizado de forma eficaz em estudos da dinâmica ambiental na representação da variabilidade espacial e temporal de processos hidrosedimentológicos em bacias hidrográficas. O método desenvolvido para modelagem descreve a dinâmica da perda de solo devido à enxurrada produzida pela água e às mudanças no uso da terra. Este permite a avaliação dos riscos de erosão do solo, utilizando um modelo implementado em um Sistema de Informação Geográfica (SIG) em modo raster. O mapeamento de cobertura e uso da terra foi realizado com base na utilização de técnicas de sensoriamento remoto e processamento digital das imagens. O estudo baseou-se no desenvolvimento de diferentes cenários de previsão de comportamento das taxas de erosão do solo, segundo mudanças da cobertura e uso da terra. Tendo em conta este procedimento, o mapeamento da erosão atual e/ou a sua predição no tempo e no espaço, desempenha um papel importante na determinação da variabilidade espacial dos fenômenos, tornando-se uma ferramenta essencial para o planejamento na conservação dos solos. Os resultados obtidos permitem avaliar a aplicabilidade do modelo na modelagem do escoamento superficial e produção de sedimentos em bacias hidrograficas em escala média com predominio de uso agrícola. Esta foi avaliada através dos resultados da simulação em uma escala de tempo mensal e anual sem calibração durante um período de 20 anos de simulação para três cenários de estudo. Foram utilizadas diferentes condições de uso e ocupação do território. A análise dos resultados das simulações no âmbito destes cenários permitiu identificar as mudanças e contrastes que ocorreram e potenciais dos processos hidrosedimentológicos na bacia, o cálculo dos volúmes do fluxo de escoamento e as taxas na produção de sedimentos anual e mensal e a sazonalidade destes processos. Neste sentido se desenvolveu uma metodologia para o cálculo e a avaliação da erosão dos solos por meio da utilização das ferramentas de geoprocessamento. Posteriormente, pretende-se aplicar esta metodologia para outras regiões do país, constituindo-se numa poderosa ferramenta para o prognóstico dos riscos à erosão nas regiões agrícolas de manejo inadequado e também, como instrumento para a tomada de decisões relativas aos impactos da erosão, acelerada pela atividade humana
Abstract: Mathematical models for predicting erosion and sediment production has great potential for use in studies of the degradation and planning of natural resources, that allow estimating impacts caused by agricultural activity. This work deals with the application of the hydrological model SWAT (Soil Water Assessment Tool), in order to forecast the risks of soil erosion due to land use changes, in the Chambas river basin, Ciego de Avila province, Cuba. This model has been successfully used in studies of environmental dynamics in the representation of spatial and temporal variability of hydro-sedimentological processes in watersheds. The method developed for modeling, describes the dynamic in the loss of soil due to runoff produced by water and changes in land use. This allows us to assess the risks in soil erosion, using a model implemented in a Geographic Information System (GIS) raster mode. In determining the mapping of land cover/land use will be use remote sensing techniques and digital image processing. The study is based on the development of different scenarios to predict behavior in the rates of soil erosion when the Land cover /land use change. Taking into account this procedure, the mapping of the existing erosion and/or its prediction in time and space, plays an important role in determining the spatial variability of the phenomena, becoming an essential tool for soils conservation planning. The results obtained allow evaluating the applicability of the model in modeling runoff and sediment yield in medium scale watersheds with predominance of agricultural use. This was evaluated through simulation results on a monthly and annual time scale without calibration over a period of 20 years of simulation to three study scenarios. We used different stages of use and occupation of the territory. The analysis of simulation results under these scenarios, allowed identifying changes and contrasts, occurring and potential in hydro-sedimentological processes in the watershed, the calculation of flow rates of runoff and sediment yield annual and monthly and the seasonality of these processes. In this sense, was developing a methodology that enables using geoprocessing tools for the calculation and assessment of soil erosion and its subsequent generalization to other regions. This provides a powerful tool for forecasting the risk of erosion in agricultural regions, which facilitates decision making about the negative effects of accelerated erosion by human activity

La calidad de vida de los ciudadanos está condicionada, entre otros aspectos, por la calidad del espacio urbano donde habitualmente desarrollan sus actividades, y es el espacio público, el medio físico donde este tipo de actividades se manifiesta. El derecho ciudadano de poder ingresar, transitar y permanecer en el espacio público, de manera segura, confortable y autónoma, son acciones que engloba el concepto de accesibilidad. Para evaluar el espacio público con una perspectiva accesible se parte de un enfoque sistémico que analiza los problemas del espacio público en su conjunto y no de los componentes aislados. Se define un modelo conceptual estructurado en cuarenta y una variables en tres unidades de análisis; el espacio público y su diseño, la accesibilidad y usos, y los principales elementos que definen los procesos físicos, cognitivos y afectivos de las personas al usar el espacio público y las principales actividades o acciones que desarrollan en el mismo. Se establecen relaciones a partir del uso del método prospectivo de Matrices de Impacto Cruzado y Multiplicación Aplicada para la Clasificación (MIC- MAC), para determinar las variables claves, las más sensibles del modelo conceptual propuesto.
La problemática del espacio público en la Habana, así como las potencialidades que promueve esta ciudad histórica consolidada, permiten aplicar el modelo conceptual propuesto, en el Vedado y La Habana Vieja. En estas zonas centrales, se han clasificado los espacios públicos, en espacios trazados tipos, de recorrido, de cruce y de estancia. Se han seleccionado el Parque Víctor Hugo, y la Plaza Vieja, así como sus calles y cruces asociados, como espacios trazados tipos, para la evaluación de la accesibilidad, a partir de las variables claves del modelo conceptual planteado.The quality of citizen life, is conditioned, among other aspects, by the quality of the urban space, where they usually develop theirs activities, and it’s the public space, the physical place where this kind of social activities manifest itself. The citizen’s rights to access, walk, and remained in the public space, safe, comfortable, and independent way, are public actions that encompass the concept of accessibility. Assessing public spaces with an accessible perspective is a systemic approach that analyses the problematic situation of the public places as a whole and not the insolate component. This thesis proposes a conceptual model of accessibility for the public spaces, structured in forty-one elements defined it in three analytical conceptual units: all about the physics aspect of the public spaces and it urban design, the second about the uses and accessibilities to the public spaces, and the main elements had defined the physical, cognitive and affective processes of the people, who use the cities, and the principals urban activities that are develop in it. The relationship of this elements is established by the use of the prospective method, Cross-Impact Matrix and Applied Multiplications for the Classifications (MIC-MAC). This method is important for decided the most sensitive key elements of the propose conceptual model for accessible public spaces. The problem of public spaces in Havana City, as well as a city with urban potential to promoted, because it’s an consolidate and historical city, allow to apply the proposed conceptual model, specific in Vedado and Old Havana. In this central urban’s areas, have been classified, it’s public spaces in different type of space like: space for the pedestrian route, crossing space and space for the stay. The Victor Hugo Park, and the Plaza Vieja Square, as well as its associated streets and street crossing, have been selected as type draw public spaces, for the evaluation of accessibility based on the key elements by the conceptual model proposed.

La repartition spatiale entre chenaies (chene vert, chene liege et chene zeen), resulte d'un ensemble de facteurs: bioclimatiques, edaphiques et biotiques favorables. L'approche dendroecologique a pour objectif de contribuer a une meilleure comprehension des relations cernes-climat. La fonction de reponse de chaque population precise le role respectif des temperatures et des precipitations mensuelles sur la croissance radiale. L'etude dendrometrique et de cubage du chene liege a permis d'evaluer la production subereuse en volume. L'etude de la biomasse et du volume du chene vert a conduit a elaborer des modeles mathematiques a partir des peuplements scleriphylles obtenus sur plusieurs cepees moyennes abattues et permettre l'elaboration de tarifs poids-secs

This thesis analyzes the Cuban medical adaptation in Venezuela called Misión Barrio Adentro (MBA) and seeks to answer the question of whether MBA shows promise as a health system that improves medical accessibility for impoverished and marginalized populations. In many cases MBA succeeds by: utilizing a free universal health care system; locating health centres in previously underserved areas; providing medical education scholarships to populations from non-traditional backgrounds; creating a catchment system based on medical accessibility; scaling up the medical workforce to 60,000 community doctors by 2019; and broadening the very praxis of what health means in a Latin American social medicine approach. However, some challenges remain including issues of corruption, fragmentation, and polarization. Issues regarding internal and external migration of Misión Sucre-trained physicians remain to be comprehensively evaluated. However, the capacitation of non-traditional medical personnel, imbued with conciencia, is significant and could well become an important example for other countries.

Full textAbstract:
Federal agencies operating along the border in southern Florida include the United States Coast Guard (USCG), United States Customs and Border Protection (USCBP), which is the parent agency for Border Patrol (BP), Immigration Customs Enforcement (ICE), and the National Park Service (NPS). Each agency has its own mission regarding immigration, and conflicts have emerged regarding responsibilities and responses to immigrant landings. The purpose of this study was to identify federal law enforcement perspectives about tactics for responses to Cuban immigrant landings within national parks in southern Florida. This study was motivated by the following research questions: 1.) How do the federal agencies operating along the southeastern border in Florida work together during responses to Cuban immigrant landings within national parks? 2.) What are the perspectives among agency personnel about tactics for response to Cuban immigrant landings within national parks? 3.) What tactics should be emphasized in future responses? The concept of shared mental models (SMM) provided a framework for the research, and data was collected through the Q method. Three factors, or social perspectives, on responses to landings were revealed: 1.) React & Transport, 2.) Protect and 3.) Plan. Implications for managers, limitations and future research is discussed.

Full textAbstract:
Part I. Novel mercaptoethoxy and mercaptoxylyleneoxy derivatives of meso-tetraphenylporphyrin, H$\sb2$TPP, and meso-tetranaphthalporphyrin, H$\sb2$TNP, with the potential for coordinating an iron-sulfur cubane cluster, have been synthesized and characterized. The thiol function is guarded during synthesis by an acetate protecting group, which is removed quantitatively by an acid-catalyzed hydrolysis reaction in the final workup step. The four "thiol-arms" on these light-sensitive porphyrins allows for the presence of atropisomers which have been observed and, in the case of the tetranaphthalporphyrin derivative, separated. The atropisomers of the acetylmercaptoxylyleneoxy derivatized tetraphenylporphyrin, H$\sb2$TAMXPP, interconvert at a rapid rate and are only observable by $\sp1$H NMR spectroscopy at $-$70$\sp\circ$C. The free-base porphyrins, in the thiol-protected form, are easily metallated by literature procedures and the zinc(II) and iron(III) chloro derivatives of these new porphyrin compounds have been synthesized and characterized.
Part II. The thiol functionality of the mercaptoxylyleneoxy derivative of tetraphenylporphyrin, H$\sb2$TAMXPP, readily exchanges for ethanethiol when H$\sb2$TAMXPP is reacted with (Fe$\sb4$S$\sb4$(SEt)$\sb4\rbrack\sp{2-}.$ The dioxygen and light sensitive product, (cation)$\sb2$ (Fe$\sb4$S$\sb4$(H$\sb2$TMXPP)) has been isolated and characterized. Mossbauer and $\sp1$H NMR spectroscopy provide evidence for the successful synthesis of the desired porphyrin/iron-sulfur cluster compound. As such, this compound is the first example for the synthesis and isolation of a 1:1 porphyrin/iron-sulfur cluster compound and provides as a first generation model compound for the siroheme/iron-sulfur cluster structural unit found at the active site of sulfite reductase.

This master thesis studies the most appropriate entry mode to Cuba for Vicaima and its subsequent stages of internationalization. I analyze the general business environment in Cuba and the attractiveness of the interior door industry in Cuba with a Pestle analysis and 5 forces of Porter, respectively, and we define the company’s organizational resource platform. I also study the pros and cons of diverse internationalization modes and concluded that a successive stage model approach is the most suitable for SME companies like Vicaima. I conclude that Vicaima should start its internationalization mode with Indirect Exportation and evolve into a servicing facility.
