Reconstruction of vertical thermal structure from several subsurface temperatures in the China Seas and adjacent waters

Empirical Orthogonal Function (EOF) analysis is used in this study to generate main eigenvector fields of historical temperature for the China Seas (here referring to Chinese marine territories) and adjacent waters from 1930 to 2002 (510 143 profiles). A good temperature profile is reconstructed based on several subsurface in situ temperature observations and the thermocline was estimated using the model. The results show that: 1) For the study area, the former four principal components can explain 95% of the overall variance, and the vertical distribution of temperature is most stable using the in situ temperature observations near the surface. 2) The model verifications based on the observed CTD data from the East China Sea (ECS), South China Sea (SCS) and the areas around Taiwan Island show that the reconstructed profiles have high correlation with the observed ones with the confidence level > 95%, especially to describe the characteristics of the thermocline well. The average errors between the reconstructed and observed profiles in these three areas are 0.69A degrees C, 0.52A degrees C and 1.18A degrees C respectively. It also shows the model RMS error is less than or close to the climatological error. The statistical model can be used to well estimate the temperature profile vertical structure. 3) Comparing the thermocline characteristics between the reconstructed and observed profiles, the results in the ECS show that the average absolute errors are 1.5m, 1.4 m and 0.17A degrees C/m, and the average relative errors are 24.7%, 8.9% and 22.6% for the upper, lower thermocline boundaries and the gradient, respectively. Although the relative errors are obvious, the absolute error is small. In the SCS, the average absolute errors are 4.1 m, 27.7 m and 0.007A degrees C/m, and the average relative errors are 16.1%, 16.8% and 9.5% for the upper, lower thermocline boundaries and the gradient, respectively. The average relative errors are all < 20%. Although the average absolute error of the lower thermocline boundary is considerable, but contrast to the spatial scale of average depth of the lower thermocline boundary (165 m), the average relative error is small (16.8%). Therefore the model can be used to well estimate the thermocline.

Morphological and genetic study of Prorocentrum donghaiense Lu from the East China Sea, and comparison with some related Prorocentrum species

In this paper, the detailed morphology of Prorocentrum donghaiense Lu from both field samples and cultures was examined, and a taxonomic comparison was made between P donghaiense and some related Prorocentrum spp. using morphological and molecular data and other published information. There were distinct differences among these species in morphological characteristics that historically have been presented as conservative features. The discrepancies extended beyond that of individual variations within the same species due to environmental factors. Therefore, these morphological features may not be conservative but, rather, polymorphic depending on environmental conditions. Based on this analysis, we suggest that the high-biomass bloom-forming species in the East China Sea, previously reported as Prorocentrum dentatum Stein, is P donghaiense Lu. The species reported from the East China Sea and Japanese and Korean waters appear to be the same species. Molecular data also suggest that P. dentatum (CCMP1517) and P. donghaiense are genetically identical. Therefore, the geographic distribution of P. donghaiense may be much wider than expected.

Spatial variability in biomass and production of heterotrophic bacteria in the East China Sea and the Yellow Sea

The distributions of heterotrophic bacterial abundance and production were investigated in the East China Sea and the Yellow Sea during the autumn of 2000 and spring of 2001. Bacterial abundance varied in the range 3.2-15.7 (averaging 5.7) x 10(5) and 2.3-13.6 (averaging 6.2) x 10(5) cells cm(-3) in the spring and autumn, respectively. During autumn, bacterial production (BP) (0.27-7.77 mg C m(-3) day(-1)) was on average 3 fold that in spring (0.001-2.04 mg C m(-3) day(-1)). Bacterial average turnover rate (ratio of bacterial production:bacterial biomass, mu=0.21 day(-1)) in autumn was 3 times as high as in spring (0.07 day(-1)). The ratio of integrated bacterial biomass to integrated phytoplankton biomass in the euphotic zone ranged from 4 to 101% (averaging 35%) in spring and 24 to 556% (averaging 121%) in autumn. The results indicate that the distributions of heterotrophic bacteria were controlled generally by temperature in spring and additionally by substrate supply in autumn. (C) 2010 Elsevier Ltd.

Holidays in the Danger Zone: Entanglements of War and Tourism

A timely, and uniquely historical, look at how war turns soldiers, and all of us, into tourists. Holidays in the Danger Zone exposes the mundane and everyday entanglements between two seemingly opposed worlds—warfare and tourism. Debbie Lisle shows how a tourist sensibility shapes the behavior of soldiers in warespecially the experiences of Western military forces in “exotic” settings. This includes not only R&R but also how battlefields themselves become landscapes of leisure and tourism. It further explores how a military sensibility shapes the development of tourism in the postwar context, from “Dark Tourism” (engaging with displays of conflict and atrocity) to exhibitions of conflict in museums and at memorial sites, as well as in advertising, film, journals, guidebooks, blogs, and photography. Focused on how war and tourism reinforce prevailing modes of domination, Holidays in the Danger Zone critically examines the long historical arc of the war-tourism nexus from nineteenth-century imperialism to World War I and World War II, from the Cold War to globalization and the War on Terror.

A governance approach to integrated rural tourism: factors influencing organisational performance and tourism support of local development organisations

Ao longo das últimas três décadas, o envolvimento das comunidades na formulação de políticas locais tem vindo a ganhar cada vez mais atenção como uma abordagem sustentável para o desenvolvimento rural na União Europeia (UE) e no mundo. Emergendo da globalização, novas estruturas de governação têm desafiado a base territorial restricta da autoridade do Estado soberano através do envolvimento de uma rede complexa e de autoorganização de atores governamentais e não-governamentais na tomada de decisões coletivas. A reestruturação territorial e institucional das zonas rurais, associada à expansão da governança rural, ganhou atenção considerável na literatura. No entanto, o potencial de empregar princípios de governança como fatores que determinam as direções de desenvolvimento rural através de desempenho organizacional e apoio no turismo não tem sido amplamente explorado na literatura. Deste modo, o principal objetivo desta tese consiste no emprego de ‘integração’, ‘participação’ e ‘empowerment’ como fatores críticos que influenciam os rumos do desenvolvimento rural (1) através do desempenho organizacional das organizações de governança rural e (2) apoio no turismo de organizações de desenvolvimento rural tendo em vista a validação da abordagem de governança para o turismo integrado. Ao longo deste duplo objectivo geral, a tese é dividida numa componente qualitativa de ‘desempenho’ e numa componente quantitativa de ‘apoio’. Seguindo uma abordagem sistemática baseada num sistema conceptual, foram realizadas 38 entrevistas em profundidade com pessoas chave envolvendo gestores do programa LEADER da UE na Hungria (34% do número total de Grupos de Ação Local [GAL]), seguido por um levantamento de campo transversal realizado através de um sistema de recolha de dados na Internet, tendo resultado em 662 questionários válidos para uma taxa de resposta de 63.6%. Os resultados da componente “desempenho” revelaram padrões na implementação dos princípios de governança, que por sua vez permitiram a identificação de fatores que permitem e restringem o desempenho organizacional. Os resultados da componente “apoio” permitiram destacar que o ponto de vista de redes de desenvolvimento local nos princípios de governança não é homogéneo. Diferenças significativas foram encontradas entre organizações responsáveis pelo planeamento e os grupos de aconselhamento. Contudo, os resultados sugeriram que a dimensão sustentável de turismo rural integrado é um prognosticador da contribuição do turismo para o desenvolvimento global da comunicade e para o apoio do turismo ao longo das redes de desenvolvimento local. Este estudo responde a uma necessidade crescente de investigação, que resulta da proliferação à escala mundial de formações de governança em sistemas de administração pública, tanto no lado dos investigadores como no lado dos praticantes.

Environmental governance in China: weakness and potential from an environmental policy integration perspective

Interest in China’s capacity for environmental governance is growing, in line with its environmental woes and exponential economic growth. Environmental policy efforts have lacked effectiveness, confirming the persistence of a disjuncture between promise and performance. This article contributes to the debate through the analytical lens of Environmental Policy Integration (EPI): a normative concept and governance regime indispensable to sustainable development. It finds that China,like most OECD countries, falls short of the concept. Despite encouraging recent changes, driven by the Hu-Wen regime, and encapsulated in the idea of scientific development, the analysis reveals weaknesses in all three EPI-type responses: normative, organisational and procedural. The disjuncture is confirmed, but drawing on EPI’s normative perspective, it is suggested that the reasons for this lie as much in the framing of the promise, as in the performance, or implementation, itself. Based on this interpretation and on China’s unique extreme characteristics, it is recommended that environmental policy objectives be given principled priority status, as a condition for effective governance.

Complexity theory and tourism policy research

This paper investigates applications of complexity theory in the social sphere and considers its potential contribution to enhance understanding of tourism policy making. Five concepts are identified to explore complex social circumstances and human interactions that influence policy. Social applications of complexity suggest a move towards localised and deeper studies to explore the dynamics of policy enactment in context. It suggests complexity theory might be used as a thinking tool to enable a more holistic approach to policy analysis and investigate policy in its context, considering interactions between different policies/programmes, and the implications of human agency.
