Studieavhopp sjökaptensprogrammet / Master mariner dropout

Andersson, Alexandra, Henwood, Erica January 2018 (has links)
Detta arbete har haft som syfte att undersöka vilka orsaker som ligger bakom valet att avbryta sina studier i förtid vid sjökaptensprogrammet, samt att kartlägga problemområden som upplevs av de studenter som valt att avsluta sina studier i förtid. Arbetet har även syftat till att undersöka huruvida anledningarna skiljer sig från tidigare forskning av ämnet. Av särskilt intresse var praktikperioden och dess inverkan för studieavhopp. För att undersöka fenomenet närmare har en kvalitativ metod med semistrukturerade intervjuer använts. Respondenterna valdes ut från en och samma klass av sjökaptensprogrammet med ingångsår 2012 för att få undersökningen så tidsmässigt relevant som möjligt. Intervjuerna har fokuserats runt förbestämda teman, vilka tidigare forskning har identifierat som avgörande faktorer som leder till avhopp. Resultatet visar att beslut om studieavhopp uppstår som en kombination av flera faktorer, och är mycket sällan resultatet av en enskild faktor. Stickprovet som undersöktes var homogen med yrkesgruppen fartygsbefäl i resten av landet och även med sina före detta klasskamrater. Utbildningen beskrevs med positiva ordalag och det sociala nätverket ansågs verka skyddande. Praktiken har visat sig vara betydelsefull i beslutet, särskilt då verkligheten ombord kolliderar med studentens förskönade bild om livet till sjöss, och var ofta den utlösande faktorn i beslutet om avhopp samband med en negativ framtidstro och ett bristande intresse för yrket. / This study aims to examine underlying causes in cases of dropout from the Master mariner programme, as well as mapping out problem areas for those students who choose to drop out. The study also aims to examine whether these causes differ from previous research in the area. Of particular interest is the role work experience plays in the decision to drop out. In order to examine the subject further a qualitative method has been used and semi structured interviews have been held with respondents from a single year commencing their studies in 2012 in order for the study to be as relevant as possible. Interviews have focused around pre-determined themes, which previous research has concluded to be of importance. Results show dropout as a result of a combination of factors, and very rarely is a single factor significant enough to describe the phenomena. The sample group was homogenous to the larger population of Officers in the Swedish merchant navy, as well as to their previous class mates. The course was described in positive terms and the social network around a student was often a protective factor. Work experience is shown to be of vital importance when a student considers dropping out, especially when reality collide with the students´own glorified expectations of life at sea. This together with a negative view on future work prospects and a general lack of interest in shipping was commonly reason for dropping out.

Maritime policy and the success of nations : the case of Greek-flagged ocean shipping

Konsta, Katerina January 2017 (has links)
In an era that national flags are dying off (Sletmo 2001) there is no dispute about the success of Greek flagged shipping. How can a small nation like Greece retain the highest percentage of all national fleets? Literature identifies that this success is due to several reasons. However, what are the elements that contribute to the success of Greek-flagged shipping? This study establishes that ‘the success of Greek ocean-going flagged shipping is a blend of a tendency for governments to experiment with various policies intended to promote national competitiveness, individual entrepreneurship, the cluster as well as culture, knowledge and skill’. Litrature from different disciplines and sources are summarised, compared, contrasted, and synthesised in order to develop a coherent outcome and gain a new perspective in the respective field. Since “policy is like beauty in the eye of the beholder…” (Roe 2007c) a multilevel, holistic, exploratory, inductive, deductive, abductive, and overall pragmatic methodological approach is considered, as the only viable option for complex research questions related to maritime policy. A three-method approach is applied with every method contributing to each other: the Timeline A to Ω and Literature Analysis, Delphi Method, and the Application of Porter’s diamond on national competitiveness. The belief that traditional flags are dying off, implies that they are not dead yet. The Greek Registry, and every ship registry is a system of people, organisations , and processes and it is that system that contributes to the success of the flag. Contrary to the belief of some players, government policy affects the size and the quality of the national flag ocean-going fleet undertaking various polices intented to promote national competitiveness. This study contributes to academic knowledge as well as to the Greek and any other registry’s competitiveness, as well as to the govenemental decision making and development of maritime policies. Recommendations are made for the Greek flag and the maritime policy, as well as for the application of the GREKON MODEL to the real maritime world and academia.

Challenges of Multimodal Transport Services:The Case of Ethiopian Shipping and Logistics Service Enterprise : Ethiopia- Sweden-Denmark and UK trade routes operation

Demse, Habtesilase Ketema January 2018 (has links)
Abstract Purpose: is to identify the challenges of multimodal transport service of ESLSE in the Europe trade routes operation from origin up to destination and to analyze the contribution of network partners to ESLSE solving these challenges.   Design\Data collection\Approach: This thesis relied on qualitative research design in order to identify the key challenges of multimodal transport services and to show how the network partners contribute to solving these challenges. Moreover, to achieve the objective of the study, semi structure interviews were used, and the responses from 14 experts were analyzed.   Theoretical framework: The theoretical base and concepts are used to determine the theoretical boundaries of the research. It provides an overview of the literature that exists in the challenges of multimodal transport services. The theoretical framework firstly encompassed the logistics performance and personnel, followed by the description of multimodal transport services, customs facilitation, ICT, infrastructure, network partner integration and port administration. Lastly, theoretical synthesis is developed that are identified from the theory to demonstrate the interrelationship between individual concepts.   Findings: The findings of this study revealed that multimodal transport service was impacted by a number of challenges even if the network partners contributed some solutions. The results of the study showed that the lack of skilled logistics personnel; poor ICT system; lack of integration between network partners; lack of effective infrastructure; inadequate and ineffective capacity of trucks; material theft; corruption; security risk; lack of prompt response in the operation between network partners; monopoly of the operation by ESLSE; and lack of quality of transported cargo are the main challenges for multimodal transport services. Managerial implication: For managers of network partners, it is recommended that they should be aware that the challenge of multimodal transport service is the result of poor ICT systems; lack of integration between network partners; lack of effective infrastructure; lack of skilled logistic personnel; inadequate and ineffective capacity of trucks; material theft; corruption; security risk; lack of quality of transported cargo; and lack of prompt response in the operation between the network partners Hence, they should take action to solve the problems by integrating with shipping agents and steering committees such as customers office, transport minister, and maritime authority. Moreover, the shipping agents managers can use the results of the study to enhance their contribution in order to solve the challenges of multimodal transport services by communicating with the ESLSE.   Limitations: The small sample size without adequately diverse geographical spread and sample of shipping agents and dry ports since the study is only limited to Europe trade routes and it did not take in to consideration other continents like Africa and Asia which could have given additional information on the topic. The sample of shipping agent and dry ports was limited with 3 out of 11 and 3 out of 7 respectively.   Originality\Value: This thesis is one of the first to analyze the challenges of multimodal transport in the case of Ethiopia to Europe trade operation by interviewing both the ESLSE and shipping agents.

Redução dos impactos ambientais causados por emissões de gases no transporte marítimo. / Reduction of the environmental impacts caused by the maritime transport.

Juan Carlos Montoya Cisneros 07 November 2011 (has links)
O transporte marítimo depende essencialmente da energia dos derivados do petróleo e, em conseqüência, produz emissões de CO2, SOX, NOX e material particulado entre outros. Hoje o transporte aquaviário responde por aproximadamente 4,5% das emissões de carbono, 4% das emissões de óxidos de enxofre e 7% das emissões de oxido de nitrogênio. Se a expansão desse modal de transporte se mantiver nos próximos anos, como se tem previsto, a sua participação na emissão destes tipos de poluentes deve aumentar e, certamente, haverá pressões da sociedade para introdução de medidas que contenham esse aumento. Pode-se afirmar que os poluentes gerados pelo Transporte Marítimo são resultado de deficiência em projeto de navios e de seus sistemas, de uma má gestão operacional, e inclusive da ausência de medidas de regulamentação mais rigorosas. O estudo se concentra em estudar dois destes pontos. O primeiro se refere ao desenvolvimento do projeto do navio e da instalação propulsora com a preocupação de reduzir o consumo de energia. Isso implica em alterações nos projetos e seus sistemas de propulsão, tirando melhor proveito da tecnologia disponível no mercado, bem como análise da viabilidade de uso de fontes alternativas de energia. O segundo ponto se refere ao processo de gestão operacional, com ênfase na redução da emissão de poluentes. Serão examinados exemplos práticos que sustentem as reduções e benefícios, por exemplo, a redução de velocidade do navio. Por ultimo foram expostas as alternativas que o autor considera as mais promissoras para atingir o objetivo pretendido. São selecionadas as melhores opções que contribuem para a redução das emissões de gases, entre as medidas tecnológicas, operacionais e de dimensionamento de frota. Algumas destas alternativas podem ser aplicadas aos navios existentes, enquanto que outras só podem ser aplicadas no projeto de navios novos. / The shipping depends on the energy of oil products, which produce emissions of CO2, SOX, NOX and particulate matter. Today, the water transport accounts for approximately 4.5% of carbon emissions, 4% of sulfur oxides emissions and 7% of nitrogen oxide emissions. If the expansion of this mode of transport is maintained in the coming years, as has been predicted, its participation in the emission of these types of pollutants must increase, and certainly there will be pressure from society for introducing measures to contain its increase. It can be argued that pollutants generated by the Maritime Transport are the result of deficiency in the design of ships and theirs systems, deficient operational management, and even the absence of more stringent regulatory measures. The study focuses on the study of these two points. The first refers to the development of Ship design and propulsion plant with a view to reducing energy consumption. This implies changes in design and propulsion systems, making best use of available technology, as well as the evaluation of viability in the use of sources of alternative energy. The second point refers to the process of operational management, with emphasis on reducing of emissions. Practical examples are examined to support and benefit the reductions of emissions, for example, the reduction of ship speed. Finally is exposed the alternatives that the author considers the most promising to achieve the desired goal. The best options are selected to reducing greenhouse gas emissions between technological measures, operational and fleet sizing. Some of these alternatives can be applied to existing ships, while others may only be applied in the design of new ships.

Análise da estrutura de financiamento à indústria naval no Brasil. / Analysis of the structure of financing to the industry of naval construction in Brazil.

Marcello Muniz da Silva 10 October 2007 (has links)
Este trabalho discute os microfundamentos do financiamento de projetos orientado à construção naval no Brasil, tendo como base de comparação práticas adotadas em outros países. A experiência brasileira é tratada metodologicamente como um \"estudo de caso\". Este procedimento se justifica em razão da natureza complexa do problema da pesquisa, importância do contexto na tomada de decisão por parte dos agentes envolvidos (armador, estaleiro, órgãos governamentais, órgãos de financiamento, etc.), escassez de informações estatísticas e escassez de estudos direcionados ao tema. A modelagem proposta abrange dois enfoques complementares. O primeiro toma como base um conjunto de indicadores econômico-financeiros de empresas de armação nacionais e estrangeiras. O objetivo é comparar a estrutura de capital das empresas de navegação nacionais e estrangeiras. Os resultados são confrontados com opiniões de agentes ligados ao setor a fim de verificar se as dificuldades no financiamento possuem relação com as causas explicitadas. Estes foram obtidos a partir de um extenso banco de dados elaborado durante a pesquisa e são analisados á luz de princípios que regem a concessão de financiamentos, incluindo critérios seguidos pelo BNDES no repasse de recursos do Fundo da Marinha Mercante (FMM). As informações geradas são confrontadas com opiniões de diretores financeiros de empresas de armação nacionais, obtidas por meio de entrevistas realizadas ao longo do desenvolvimento do projeto. Essa investigação é complementada pelo posicionamento de especialistas vinculados às associações classistas que atuam ao setor. O intuito é apontar e discutir a percepção destes atores sobre os obstáculos do financiamento local. O segundo enfoque, ainda baseado nas informações contidas no banco de dados e nas entrevistas realizadas no âmbito da pesquisa, estabelece um modelo, baseado na teoria financeira, destinado a avaliar o nível de atratividade do financiamento setorial. A determinação do modelo tem como ponto de partida a estimação da taxa de retorno setorial por meio da aplicação de técnicas econométricas de cointegração sobre dados de ações de 44 empresas de transporte marítimo e índices de mercado obtidos juntos ao New York Stock Exchange (NYSE). O modelo proposto e executado por meio de simulação computacional é também alimentado por parâmetros das estruturas de financiamento de diversos países e estatísticas que captam os respectivos níveis de risco associados à transferência de recursos. Quando executado, o modelo considera e compara uma operação de financiamento feita por uma empresa de transporte local para a construção de uma embarcação em estaleiro nacional a qual submete a proposta a diferentes linhas de financiamento. O procedimento adotado confronta a estrutura de financiamento brasileira com as praticadas no Japão, Coréia do Sul, Alemanha, Noruega, China e EUA. O grau de atratividade do financiamento local é resumido por meio de índices de atratividade gerados pelo modelo. O estudo termina discutindo os resultados da modelagem e apresentando uma síntese de microfundamentos que orientam o financiamento destinado à construção de embarcações. / This dissertation presents the micro foundations of the naval construction project finance in Brazil, as it can be compared to practices of other countries. The Brazilian experience is treated methodologically as a \"study case\". This procedure is justified due not only to the exploratory nature of the research question on a quite complex subject but also to the relevance of the decision making process of major actors involved (shipowner, shipbuilder, regulatory agency, financial agencies, etc.), scarcity of data, information and other previous specific studies. The methodology developed has two complementary perspectives. The first takes as its base a set of economic and financial indicators of Brazilian and foreign merchant marine firms. The indicators were obtained through an extensive data collection undertaken during this research and are analyzed by the same parameters used by the National Economic and Social Development Bank - BNDES in its loan mechanisms to the Marine Merchant Fund - FMM. The information is then submitted to an analysis of financial executives of naval construction firms and leaders of entrepreneur\'s organizations, by means of structured interviews. The objective is to point out and discuss the perception of these important actors on the structural constraints of the Brazilian financial system. The second perspective, based on the data collected and on the interviews realized, establishes a theoretical finance simulation model to measure how attractive are the investments in the naval sector. The model is specified through the estimation of the rate of return in the sector. Cointegration econometric techniques are applied to data of 44 marine transportation firms, utilizing market indicators obtained in the New York Stock Exchange (NYSE). The model is also fed by parameters of several countries\' financial structure as well as statistics that capture the risk level in each case. The model considers and compares one project submitted by a single firm to different financial lines. The adopted procedures are able to compare the Brazilian structure of finance to the practices undertaken in Japan, South Korea, Germany, Norway, China and United States. The degree of attraction of the local financial system is summarized by a system of \"attraction index\" generated by the model. The study ends up with a discussion of the outputs of the model and presents a synthesis of the micro foundations that should subsidy the naval construction industry.
