Relatório de estágio no Praia D’El Rey Marriott Golf & Beach Resort: Melhoria das operações através dos recursos existentes

Durante o período de estágio curricular, no âmbito do Mestrado em Gestão e Direção Hoteleira, que decorreu de 1 de Novembro de 2013 a 31 de Julho de 2014, nos departamentos de Direção de F&B, At Your Service e Relações Públicas e Eventos do Praia D’El Rey Marriott Golf & Beach Resort, verificou-se que, em algumas e diferentes situações, não existia uma gestão eficaz entre os recursos existentes e a própria operação. O objetivo do presente trabalho pretende mostrar como, muitas vezes, através dos próprios recursos se consegue melhorar a operação e, consequentemente, os resultados. Efetuou-se uma análise de observação à operação e, ao mesmo tempo, interagiu-se diretamente com os recursos humanos, no intuito de se detetarem falhas que se consigam evitar através dos próprios recursos, ou seja, sem custos para a empresa. Na Direção de F&B pôs-se em prática um dos standards exigidos pela cadeia Marriott, o Art of Host. Este standard será abordado ao longo do presente trabalho, contudo, a sua principal vantagem é, sem dúvida, a melhoria da comunicação entre equipas e a partilha de ideias e conhecimentos. Ainda na área do F&B, mas já a nível de compras e fornecedores, também se realizaram estudos e análises que se revelaram importantes para uma melhor gestão da operação. No departamento de At Your Service, verificou-se uma falha no conhecimento da carta de room-service, por parte dos PBX Operators. Assim, realizou-se um taste panel para todos os colaboradores deste departamento e os resultados foram bastante positivos. Já na área das Relações Públicas e Eventos, projetou-se e criou-se um espaço que funciona como um Resort Information Office, ou seja, um ponto de informação do resort onde, ao mesmo tempo, se promovem eventos. Um projeto dinâmico e eficaz. As ações implementadas, no geral, demonstraram que, de facto, conseguem-se melhorias na operação, muitas vezes, através dos recursos existentes. Recomenda-se a adoção futura e contínua deste tipo de iniciativas e ações para que se obtenham resultados cada vez melhores.

(Table 2) Grain composition of sediments from ODP Hole 161-974B and from beach samples

Miocene to Pleistocene sand and sandstone were recovered at Ocean Drilling Program Site 974 in the Tyrrhenian Basin and Sites 976 and 977 in the Alboran Basin. Sand detrital modes were determined for 45 samples from these sites, as well as 10 samples of Spanish beach sand. At Site 974, the Pleistocene section includes a number of volcaniclastic (vitric ash) and terrigenous sand layers; the latter are heterogeneous and contain sedimentary and metamorphic lithic fragments. Submarine canyon and onshore drainage patterns suggest that the most likely source of this sediment is the Tiber River drainage basin in central Italy, where a Pleistocene volcanic field is superimposed on Apennine orogenic rocks. In contrast, the Miocene sand in Unit III at Site 974 may have been derived from local basement highs. The quartzolithic composition and preponderance of metamorphic and sedimentary lithic debris in sand samples from Unit II at Site 976, Unit I at Sites 977 and 978, and Unit I at Site 979 are consistent with derivation from metamorphic rocks and sedimentary cover sequences that crop out in the Betic Cordillera of southern Spain (976-978) and in the Rif of Northern Africa (979). The sedimentary to metamorphic lithic fragment ratios in these samples reflect the relative proportion of metamorphic and sedimentary rocks exposed in onshore source terranes. In contrast, the source of the few quartzose Pleistocene sands at Site 976 was likely the Flysch Trough Units that crop out near Gibraltar. The significant volcanic component in certain intervals at Sites 976 (upper Miocene) and 977 (lower Pliocene to Miocene) is consistent with widespread volcanic activity during basin inception and development. Mean sand detrital modes for sand subgroups from both the Alboran and Tyrrhenian Basin sites plot in the Recycled Orogenic and Magmatic Arc compositional fields of Dickinson et al. (1983, doi:10.1130/0016-7606(1983)94<222:PONAPS>2.0.CO;2), reflecting the hybrid tectonic histories of these basins.

Mineralcomposition of beach sediments from the area "Fähre Großenbrode-Kliff Wulfen" on Fehmarn

Um die Insel Fehmarn und an der Nordküste Wagriens wurden rund 2500 Strand-, Flachwasser- und Seesandproben zum Erkennen der Materialtransportwege sedimentpetrographisch untersucht. Für die Schwermineralbestimmung wurde hauptsächlich die Fraktion 0,2-0,1 mm herangezogen, da diese für die vorliegenden Sedimente charakteristisch ist. Da die Mineralzusammensetzung der Sedimente im gesamten Untersuchungsgebiet gleich ist, also nirgends örtlich sog. Leitminerale zugeführt werden, wurden bei der Auswertung der Analysenergebnisse die hydrographischen Verhältnisse der westlichen Ostsee und die Abhängigkeit des Sedimentes von der Kraft des bewegten Meerwassers beachtet. Bezüglich der Abhängigkeit des transportierten Materials von der Wasserkraft werden drei voneinander abweichende Systeme, nämlich der Strand, die Brandungszone und das tiefere Wassergebiet, erkannt. Am Strand ist die angewandte Untersuchungsmethode sowohl an langgestreckten Küsten als auch in stark untergliederten Ufergebieten zum Erkennen der Sandwanderbahnen geeignet. Erosion und Neuzuführung von Material auf dem Transportwege zeigen das gleiche mineralische Bild, und eine Entscheidung, welcher dieser beiden Fälle tatsächlich vorliegt, kann nur im Gelände getroffen werden. Die Korngrößenanalyse allein ist zur Beantwortung vorliegender Fragestellungen nicht brauchbar, weil durch gegebene hydrographische Bedingungen die Korngröße in Transportrichtung sowohl abnehmen als auch zunehmen kann. In Strandgebieten mit veränderter natürlicher Beschaffenheit der Sedimente und an Küsten mit ausgedehnten vorgelagerten materialliefernden Abrasionsflächen ist die Grenze der Methode aufgezeigt. Höfte, Haken und Sandinseln zeigen jeweils typische mineralische Zusammensetzungen ihres Strandes, aus welchen die Entstehung der betreffenden Anlandungsformen abgeleitet werden kann. Quer über die Brandungszone weisen die Sedimente auf engem Raum wechselnde Mineralzusammensetzung auf, aus der auf die örtlichen hydrographischen Verhältnisse geschlossen werden kann. Zum Vergleich sedimentpetrographischer Ergebniswerte sind nur Sande, die unter gleichen Ablagerungsbedingungen entstanden sind, geeignet. Zum Erkennen der Materialwanderwege wurden entweder Sandproben von den Riffkämmen oder aus den Rinnen zwischen zwei Sandanhäufungszonen untersucht. In beiden Fällen wurden die Transportrichtungen erkannt. In Gebieten, in denen die Strandsanduntersuchungen negativ verliefen, ließen die Riffsandproben Schlüsse auf die Materialschüttungsrichtungen zu. An exponierten Küsten mit mehreren wirksamen Windrichtungen darf jedoch nicht von dem einen auf das andere Wandersystem geschlossen werden. Eine Umkehr der Materialvertriftung zwischen Flachwasser und Strand kann vorliegen. Im tieferen Wasser ist es möglich, mit gleicher Methode unter Berücksichtigung der Morphologie des Meeresgrundes die Materialschüttungsrichtung zu erkennen. Zur Sedimentuntersuchung auf Linienprofilen sind nur Proben gleicher Wassertiefe geeignet; die Sonderung des Materials nach der Tiefe muß beachtet werden. Aus den ermittelten sedimentpetrographischen Werten lassen sich eine Reihe von Beziehungen ablesen, die zur Deutung der Mineralgesellschaft und für die Auswertung der Untersuchungsergebnisse herangezogen werden können. Als regionales Ergebnis der vorstehenden Untersuchung kann eine Karte der Küsten Fehmarns und Nordoldenburgs vorgelegt werden, in der die Sandwanderungswege am Strand, in der Flachwasserzone und in den daran anschließenden tieferen Wassergebieten dargestellt sind.

Publicidad de Guerrilla: Estudio de la campaña Coronita Save the Beach

En el presente artículo se realiza una reflexión sobre la relación existente entre las nuevas formas publicitarias de Guerrilla y el arte conceptual de los años setenta; en concreto refiriéndose a una campaña como es Coronita Save the Beach de la compañía mexicana de cervezas Coronita. Estas formas publicitarias de guerrilla han surgido como solución a la crisis de los formatos tradicionales de los medios de comunicación y a la saturación publicitaria. Son, a su vez, formatos novedosos en el ámbito publicitario, pero se ejecutan en base a esquemas artísticos del siglo XX surgidos a raíz de la crisis del objeto artístico de los años setenta. Esta crisis supuso el origen del arte conceptual, movimiento artístico que buscaba la supremacía de la idea frente al objeto artístico en sí. El arte siempre ha sido vanguardia cultural y social. Desde este punto de vista, se ha analizado esta campaña que se vale de estas vías alternativas de comunicación, estableciendo una relación entre arte y publicidad.

High plasticity of loggerhead nesting site fidelity: from using repeatedly the same small beach during different seasons to deposit consecutive nests in different islands distant more than 100 km

[EN] Sea turtles exhibit a strong natal homing associated with a high nesting site philopatry. Mark-recapture and genetic studies confirm these patterns suggesting differences among and within species. In the present study, we have analysed the degree of nest site fidelity of a loggerhead population nesting on the islands of Cape Verde and have evaluated the existence of intrapopulational variability in this trait. The loggerhead is the only sea turtle species that nests in Cape Verde, and 15,000–25,000 nests per season have been estimated for the whole archipelago.

Rate predation on the nesting of Caretta caretta because of Ocypode cursor in Calheta de Pau beach, Boa Vista Island (Cape Verde Rep.)

[EN] Located in the Cape Verde Archipelago is one of the most important nesting population of Caretta caretta, Boa Vista Island being the principal nesting area. This population has been subject of research since 1998.

Study of environmental radioactivity in Las Canteras beach

[EN]In this final degree work an assessment of the impact of environmental radioactivity, mainly on bathers of the most important beach in Las Palmas de Gran Canaria (Las Canteras), has been done. For this purpose, the main radionuclides contained in intertidal superficial sand samples have been measured by using gamma spectrometry analysis. Also alpha activity of the beach water was determinated by means of ZnS(Ag) scintillation detector. The radioactivity detected was due to the natural occurring radionuclides 226Ra (238U- series), 232Th and 40K in sand samples with an average activity concentrations of 14.6±1.0, 17.4±1.0 and 528±24 Bq/kg, respectively. From these values, the outdoor annual effective dose was of 0.047 mSv/y, which is below to the world’s average value (0.07 mSv/y)

Geotechnical properties of the Cassino Beach mud

Knowledge of the marine soils properties, together with hydrodynamic and climatic data, plays an important role for a better understanding of the dynamic behavior of sandy and muddy coasts. This paper deals with reporting and basic interpretation of two campaigns of exploration and characterization of the mud of Cassino Beach, southern Brazil, carried out during the years of 2004 and 2005. Samples were obtained by means of cores collected at some locations offshore, and were submitted to various laboratory geotechnical tests, including determination of the physical index, grain size distribution, Atterberg limits, and shear resistance by both triaxial and shear vane tests. Results confirm the existence of a very soft soil deposit offshore Cassino Beach, highly plastic, compressible, and viscous, forming an important database for further studies.

The response of surf-zone phytoplankton to nutrient enrichment (Cassino Beach, Brazil)

To understand the mechanisms that trigger changes in chlorophyll a and species composition in the phytoplankton of the surf-zone at Cassino Beach (RS), we performed two short nutrient-enrichment experiments (4–5 days each) during the summer and winter of 2010. Seawater was incubated under controlled conditions of temperature (summer 25± 3 °C, winter 18±1 °C), salinity (summer 28, winter 26) and irradiance (100 μmol m−2 s−1 ). Dissolved inorganic nutrients were added in various concentrations in the summer (silicate, Si; nitrate, N; phosphate, P) and winter (N, P) experiments. Samples were taken daily for cell counts and chlorophyll a analysis. In both experiments, chlorophyll a values and cell density showed a significant increase (mainly diatoms) in the treatments with nitrate addition, regardless of the proportion added. In the summer experiment, the largest chlorophyll a increase, approximately threefold (31.5 to 89.5 μg L−1 ), was observed in the NP treatment due to the growth of Asterionellopsis glacialis (Castracane) Round, Skeletonema tropicum Cleve, Thalassiosira sp. Cleve and Pseudo-nitzschia spp. Peragallo. The maximum growth was obtained in the SiNP treatment for S. tropicum (μ=0.7), Thalassiosira (μ= 1.9) and Pseudo-nitzschia (μ= 1.3) and in the SiN treatment for A. glacialis (μ= 1.0). In the winter experiment, the chlorophyll a content increased 4.2 and 5.5 times, respectively, in the N and NP treatments (maxima 38.8 μg L−1 and 31.5 μg L−1 ), where A. glacialis (μ= 1.7–1.9) and Cylindrotheca closterium (Ehrenberg) Reimann & J.C. Lewin (μ= 1.0–1.96) showed the highest amount of growth. These results indicate that nitrate is the most important nutrient controlling phytoplankton chlorophyll a at sandy Cassino Beach. However, the responses of different species to enrichment during the summer and winter indicated that other factors also played a role. A. glacialis, present during both seasons, presented the highest growth rate during the winter, whereas during the summer it was independent of nutrient enrichment but coincided with the lowest growth of S. tropicum. This finding suggested the occurrence of allelopathic interactions between these species. During the summer, multi-enrichment (SiNP) favoured the best growth of S. tropicum, Pseudo-nitzschia spp. and Thalassiosira sp. These results indicated that the phytoplankton composition and diversity in the surf zone of Cassino Beach are shaped by the availability of silicate and phosphorus as well as by the availability of nitrate.
