Qualidade nos serviços turísticos náuticos no Alto Douro Vinhateiro: perspetiva dos clientes internos (colaboradores)

No contexto atual, marcado pela crise económica e financeira, as organizações dos serviços turísticos procuram aliar o conceito de qualidade com os seus serviços, de modo a satisfazer os clientes internos (colaboradores) e os clientes externos (turistas) e a garantir a prestação de um serviço personalizado e de excelência. O objetivo da presente dissertação consiste em proporcionar uma visão geral da qualidade dos serviços turísticos náuticos efetuados na região do Alto Douro Vinhateiro (ADV), junto dos clientes internos (colaboradores). Para o efeito, foi aplicado um inquérito a 117 colaboradores de diversas organizações dos serviços turísticos náuticos da região do ADV e realizada uma pesquisa exploratória e descritiva. Os resultados obtidos demonstram que existem aspetos a serem melhorados nas organizações (preocupação com os colaboradores; formação especifica; condições de trabalho; maior dialogo entre chefias e colaboradores; atribuição de carga horária e de folgas) para que os colaboradores se sintam satisfeitos. Por outro lado, verificou-se que as perceções sobre a qualidade nos serviços turísticos náuticos são iguais em ambos os géneros; Abstract: Quality in Nautical Touristic Services in Alto Douro Vinhateiro – The Internal Clients (Collaborators) Perspective In the actual context marked by the economic and financial crisis, the organizations of touristic services are looking to ally the concept of services with their services, in order to satisfy internal customers (collaborators) and external costumers (tourists) and to guarantee the installment of an excellent and personalized service. The aim of this thesis is to provide an overview of the quality of nautical tourism services made in the region of Alto Douro Vinhateiro, with internal clients (employees). For this purpose it applied a survey of 117 employees from various organizations of nautical tourism services of the ADV region and conducted an exploratory and descriptive research. The results show that there are areas to be improved in organizations (preoccupation with employees; specific training,; working conditions; greater dialogue between managers and employees; allocation of hours and days off) so that employees can feel satisfied- Moreover it was found that the perceptions of the quality of nautical tourism services are equal in both sexes.

The 1998-2001 submarine lava balloon eruption at the Serreta Ridge (Azores archipelago): constraints from volcanic facies architecture, isotope geochemistry and magnetic data

The most recent submarine eruption observed offshore the Azores archipelago occurred between 1998-2001 along the submarine Serreta ridge (SSR), ~4-5 nautical miles WNW of Terceira Island. This submarine eruption delivered abundant basaltic lava balloons floating at the sea surface and significantly changed the bathymetry around the eruption area. Our work combines bathymetry, volcanic facies cartography, petrography, rock magnetism and geochemistry in order to (1) track the possible vent source at seabed, (2) better constrain the Azores magma source(s) sampled through the Serreta submarine volcanic event, and (3) interpret the data within the small-scale mantle source heterogeneity framework that has been demonstrated for the Azores archipelago. Lava balloons sampled at sea surface display a radiogenic signature, which is also correlated with relatively primitive (low) 4He/3He isotopic ratios. Conversely, SSR lavas are characterized by significantly lower radiogenic 87Sr/86Sr, 206Pb/204Pb and 208Pb/204Pb ratios than the lava balloons and the onshore lavas from the Terceira Island. SSR lavas are primitive, but incompatible trace-enriched. Apparent decoupling between the enriched incompatible trace element abundances and depleted radiogenic isotope ratios is best explained by binary mixing of a depleted MORB source and a HIMU­type component into magma batches that evolved by similar shallower processes in their travel to the surface. The collected data suggest that the freshest samples collected in the SSR may correspond to volcanic products of an unnoticed and more recent eruption than the 1998-2001 episode.
