Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

A guide for practical implementation in adult and pediatric emergency department and urgent care settings
The Fourth National Climate Assessment (NCA4) fulfills that mandate in two volumes. This report, Volume II, draws on the foundational science described in Volume I, the Climate Science Special Report (CSSR).2 Volume II focuses on the human welfare, societal, and environmental elements of climate cha...nge and variability for 10 regions and 18 national topics, with particular attention paid to observed and projected risks, impacts, consideration of risk reduction, and implications under different mitigation pathways. Where possible, NCA4 Volume II provides examples of actions underway in communities across the United States to reduce the risks associated with climate change, increase resilience, and improve livelihoods.

2nd edition. The purpose of this document is to provide a generic model that can be used for risk assessment of larviciding and mollusciciding; it aims to harmonize the risk assessment of such pesticides for public health use. The assessment considers both adults and children (all age groups) as we...ll as people in the following specific categories:
those handling products and preparing/loading the spray liquid in application equipment;
those applying the spray or other formulations; and
residents who may come into contact with treated waters during washing, bathing, fishing or any other activity, or use the treated waters.

In 1964 medical mission was challenged and called to define its distinctiveness and its special role in the context of that particular time. The consultation "Tuebingen I" clearly stated: "The Christian church has a specific task in the field of health and healing"1, and developed a conce...pt of wholeness and of the role of the congregation in health provision. 50 years later, the question of the proprium of Christian health services is again a very important one. At a time when governments, international non-governmental organizations and other philanthropic organizations participate in health care, the question has to be asked: What is the specific contribution of a Christian health service or ministry of healing? At a time when chronic disease challenges not only rich but now also poor countries, when infections like Ebola that for years were hidden in Africa pose a threat to the global situation, Christians have to reflect on the question of the proprium of Christian health care.

Country Strategic Plan Evaluations (CSPEs) encompass the WFP strategy and entirety of WFP activities during a specific period. Their purpose is twofold: 1) to provide evaluation evidence and learning on WFP's performance for country-level strategic decisions, specifically for developing the next Cou...ntry Strategic Plan (CSP) and 2) to provide accountability for results to WFP stakeholders. These evaluations are mandatory for all CSPs and are carried out in line with the WFP Policy on Country Strategic Plans and the WFP Evaluation Policy.

Catholic hospitals and other health services provide invaluable care to many in the community. This article accentuates the pastoral nature of Catholic health care, which is definitive to its Catholic identity. Discussing contemporary Catholic health care in conjunction with the works of Henri Nouwe...n we explore the challenges faced by today’s Catholics in Catholic health care and respond to these issues. In support of the discussion are the results of qualitative research into the perceptions Perth parishioners have of Catholic health care’s pastoral nature and Catholic identity. This research aims towards understanding the challenges facing Catholic health care providing pastoral care within its Catholic identity.
