Distribution And Ecology

Meiofauna are a component of aquatic environments from polar to tropical regions. They may colonize all types of habitats and include very enigmatic and exclusive taxa. The biodiversity of this component in marine ecosystems is far from being accurately estimated, but this would be a new challenge given the importance that meiofaunal components may play in marine ecosystem functioning and processes. This Special Issue collects many interesting topics in research on meiofauna contributing to plugging a gap on several key issues in their biodiversity, distribution, and ecology, from numerous regions that include the USA, Brazil, French Guiana, Costa Rica, Mexico, Cuba, Italy, Kuwait, Vietnam, Madagascar, the Maldives, and South Korea.

AbstractIn epidemiology, the modeling of epicenters is important both conceptually and mathematically. This paper is an attempt to model epicenters mathematically. We present an algorithm to find new epicenters. Applying our model for the data related to COVID-19 pandemic, we obtain epicenters in China, South Korea, Iran, Italy, France, Germany, Spain, the USA, and Switzerland, on the days 1, 35, 42, 42, 49, 50, 50, 50, and 56, respectively. Although the number of these epicenters is less than 5% of all contaminated countries across the globe, as of March 22, 2020, they make up 74% of new cases and over 80% of total confirmed cases. Finally, we conclude that we expect to face three new epicenters between March 22 and April 1, 2020.

Agar-agar manufacturing was Japan’s monopoly for about 300 yr from 1644 until about 1920, when its production was initiated in the USA by introducing techniques from Japan, and then was begun in South Korea, Indonesia, and many other countries. Today the average annual output of agar-agar of over 20 countries amounts to 6000 tons, half of which is produced in Japan.Agarophytes are harvested in many countries and traded among them. In Japan, nearly 14,000 tons are consumed in a year, two thirds of which are imported from about 20 countries.Under these circumstances, there is a worldwide demand for appropriate measures for resource conservation, effective harvesting, and utilization of agarophytes.This paper presents the results of basic and applied investigations on the agarophytes and the existing state of harvesting and resource-conservation management in Japan.

Abstract. We present a summary of biomass data for 11 Plankton Functional Types (PFTs) plus phytoplankton pigment data, compiled as part of the MARine Ecosystem biomass DATa (MAREDAT) initiative. The goal of the MAREDAT initiative is to provide global gridded data products with coverage of all biological components of the global ocean ecosystem. This special issue is the first step towards achieving this. The PFTs presented here include picophytoplankton, diazotrophs, coccolithophores, Phaeocystis, diatoms, picoheterotrophs, microzooplankton, foraminifers, mesozooplankton, pteropods and macrozooplankton. All variables have been gridded onto a World Ocean Atlas (WOA) grid (1° × 1° × 33 vertical levels × monthly climatologies). The data show that (1) the global total heterotrophic biomass (2.0–6.4 Pg C) is at least as high as the total autotrophic biomass (0.5–2.6 Pg C excluding nanophytoplankton and autotrophic dinoflagellates), (2) the biomass of zooplankton calcifiers (0.9–2.3 Pg C) is substantially higher than that of coccolithophores (0.01–0.14 Pg C), (3) patchiness of biomass distribution increases with organism size, and (4) although zooplankton biomass measurements below 200 m are rare, the limited measurements available suggest that Bacteria and Archaea are not the only heterotrophs in the deep sea. More data will be needed to characterize ocean ecosystem functioning and associated biogeochemistry in the Southern Hemisphere and below 200 m. Microzooplankton database: doi:10.1594/PANGAEA.779970.

Purpose While there is burgeoning service literature identifying consumer vulnerabilities and questioning the assumption that all consumers have the resources to co-create, limited research addresses solutions for consumers experiencing vulnerabilities. Service systems can provide support for consumers but can also create inequities and experienced vulnerabilities. This paper aims to identify current and further research needed to explore this issue and addresses marketplace problems for consumers experiencing vulnerabilities. Design/methodology/approach This viewpoint discusses key issues relating to solving marketplace problems for consumers experiencing vulnerabilities. A call for papers focused on solving marketplace problems for consumers experiencing vulnerabilities resulted in a large number of submissions. Nine papers are included in this special issue, and each one is discussed in this editorial according to five emergent themes. Findings Vulnerabilities can be temporary, or permanent, and anyone can suddenly experience vulnerabilities. Inequities and vulnerabilities can be due to individual characteristics, environmental forces, or due to the structure of the marketplace itself. Solutions include taking a strengths-based approach to addressing inequities and using a multiple-actor network to provide support. Practical implications The recommendations addressed in this paper enable more positive approaches to solving marketplace problems for consumers experiencing vulnerabilities. Social implications Taking a solutions-focused lens to research relating to vulnerabilities will contribute toward addressing inequities within the marketplace. Originality/value Increasingly, service literature is identifying inequities; however, very limited research addresses solutions for solving marketplace problems for consumers experiencing vulnerabilities. This paper suggests taking an approach focusing on strengths, rather than weaknesses, to determine strategies, and using the support of other actors (Transformative Service Mediators) where required.

BackgroundThis study aimed to compare treatment outcomes between patients with severe pelvic fractures treated at a representative trauma center that was established in Korea since 2015 and matched cases treated in the USA.MethodsTwo cohorts were selected from a single institution trauma database in South Korea (Ajou Trauma Data Bank (ATDB)) and the National Trauma Data Bank (NTDB) in the USA. Adult blunt trauma patients with a pelvic Abbreviated Injury Scale >3 were included. Patients were matched based on covariates that affect mortality rate using a 1:1 propensity score matching (PSM) approach. We compared differences in outcomes between the two groups, performed survival analysis for the cohort after PSM and identified factors associated with mortality. Lastly, we analyzed factors related to outcomes in the ATDB dataset comparing a period prior to the implementation of the trauma center according to US standards, an interim period and a postimplementation period.ResultsAfter PSM, a total of 320 patients (160 in each cohort) were identified for comparison. Inhospital mortality was significantly higher in the ATDB cohort using χ2 test, but it was not statistically significant when using Kaplan-Meier survival curves and Cox regression analysis. Moreover, the mortality rate was similar comparing the NTDB cohort to ATDB data reflecting the post-trauma center establishment period. Older age, lower systolic blood pressure (SBP) and Glasgow Coma Scale (GCS) at admission were factors associated with mortality.DiscussionMortality rate after severe pelvic fractures was significantly associated with older age, lower SBP and GCS scores at admission. Efforts to establish a trauma center in South Korea led to improvement in outcomes, which are comparable to those in US centers.Level of evidenceLevel IV.

The Cold War

Treaty between the United States of America and the Russian Federation on measures for further reduction and limitation of strategic offensive arms (“New START”) is the last pillar of the arms control regime on which the end of the Cold War and the new world order rested. Its expiration on 5 February 2021 is a top security challenge and indicates a possible new strategic arms race. However, can the United States and Russia still preserve the existing strategic arms control by extending the Treaty for another five years? What are the prospects, the opportunities and obstacles for this extension? What are the most pressing issues USA and Russia face with in order to preserve strategic arms control and are they willing to do so? In order to answer to these research questions author analyses several key issues that are of paramount importance for extension of the New START: nuclear modernization processes, invention of new weapons and emergence of new warfare domains; transparency and verification and broader confidence building measures; missile defence and prompt global strike; tactical nuclear weapons in Europe and Asia; general US-Russia relations which include question of democratic capacity; and broader influence of this Treaty on nuclear non-proliferation regime. By using content and discourse analysis author concludes that, although it is obvious that the extension of the New START would be primarily in favour of Russia and that the USA has not much to gain, the character of strategic stability in the Third Nuclear Age gives reasons to believe that the New START will be extended for another five years.
