Abstract

The microbial community in the oligotrophic North Pacific Subtropical Gyre is dominated by unicellular microorganisms less than a few micrometers in size. Despite the persistent low nutrient concentrations, phytoplankton growth rates appear near maximal, sustained by the recycling of nutrients with plankton population sizes regulated by processes such as zooplankton grazing and viral lysis. Seasonal pulses of particle export to the deep sea and increases in phytoplankton abundance occur during the summer months; however, the factors that result in these imbalances in growth and loss processes are not well understood. Nonetheless, as a result of persistent fieldwork and development of sensitive methodologies, the biogeochemical and ecological dynamics occurring over timescales ranging from diel to interannual are being revealed. This Research Topic covers multiple aspects of microbial oceanography in the oligotrophic North Pacific Subtropical Gyre including identification and isolation of microorganisms, quantification of microbial biomass and turnover, metabolism and physiological activities, and microbial-mediated biogeochemical cycling.All of the papers use field data collected by either the Hawaii Ocean Time-series (HOT) program, the Center for Microbial Oceanography: Research and Education (C-MORE) or the Simons Collaboration on Ocean Processes and Ecology (SCOPE). These three programs have greatly increased our understanding of microbial ecology and biogeochemical cycling in the NPSG, in part by providing unparalleled access to the NPSG on oceanographic research vessels.

Abstract

In the United States, much of the research is focused on developing new and very expensive technologies and drugs - often without a major therapeutic benefit. In resource limited countries, basic oncology care is frequently lacking. In addition, the benefits of various chemo-radiotherapy combinations for a number of malignancies are unknown as these populations have not been adequately investigated. For oncologists in these countries who have marginal to adequate resources, accrual to clinical trials is virtually non-existent to minimal, due to the complexities of their population and competing co-morbidities. As a result, there is a tremendous disparity in treatment outcomes for these populations, compared to those in developed countries. Therefore, we have asked a number of oncologists from different parts of the world to report their experience. Topics that will be covered include locally advanced breast and cervical cancer (India, South Africa), human resources for cancer control in India, systematic review of radiation resources in low and middle income countries, planning national radiotherapy services, building sustainable partnerships through the newly formed ICEC (International Cancer Export Corps), cancer disparities among American Indians, and training radiation oncologists in these under served parts of the world. Authors will discuss "lessons learned" from their populations, practical suggestions to address these disparities, and how we as a global oncology community can address, and mitigate these global challenges. The editorial by Dr. Coleman and myself highlights the invaluable contributions from our global contributors. Thank you for taking the time to read this special issue on global cancer disparities. We are all energized to begin addressing the needs of our cancer patients worldwide.

Abstract

In the last few decades, Japanese popular culture productions have been consolidated as one of the most influential and profitable global industries. As a creative industry, Japanese Media-Mixes generate multimillion-dollar revenues, being a product of international synergies and the natural appeal of the characters and stories. The transnationalization of investment capital, diversification of themes and (sub)genres, underlying threat in the proliferation of illegal audiences, development of internet streaming technologies, and other new transformations in media-mix-based production models make the study of these products even more relevant today. In this way, manga (Japanese comics), anime (Japanese animation), and video games are not necessarily products designed for the national market. More than ever, it is necessary to reconcile national and transnational positions for the study of this cultural production.The present volume includes contributions aligned to the analysis of Japanese popular culture flow from many perspectives (cultural studies, film, comic studies, sociology, etc.), although we have emphasized the relationships between manga, anime, and international audiences. The selected works include the following topics:• Studies on audiences—national and transnational case studies;• Fandom production and Otaku culture;• Cross-media and transmedia perspectives;• Theoretical perspectives on manga, anime, and media-mixes.
