Relationships between solar activity and climate change

The relationship between recurrent droughts in the High Plains of the United States and the double sunspot cycle is discussed in detail. It is suggested that high solar activity is generally related to an increase in meridional circulation and blocking patterns at high and intermediate latitudes, especially in winter, and the effect is related to the sudden formation of cirrus clouds during strong geomagnetic activity that originates in the solar corpuscular emission

Subgeometric ergodicity of strong Markov processes

We derive sufficient conditions for subgeometric f-ergodicity of strongly Markovian processes. We first propose a criterion based on modulated moment of some delayed return-time to a petite set. We then formulate a criterion for polynomial f-ergodicity in terms of a drift condition on the generator. Applications to specific processes are considered, including Langevin tempered diffusions on R^n and storage models.Comment: Published at http://dx.doi.org/10.1214/105051605000000115 in the Annals of Applied Probability (http://www.imstat.org/aap/) by the Institute of Mathematical Statistics (http://www.imstat.org

Physician Assisted Dying: A Turning Point?

Physician Assisted Dying (PAD) has been lawful in some countries since the 1940s and in the United States since 1997. There is a body of social and scientific research that has focused on whether the practice has been misused and whether gaps exist in legislative safeguards. There are multiple concerns with physicians assisting patients to die: incompatibility with the physician’s role as a healer, devaluation of human life, coercion of vulnerable individuals (e.g., the poor and disabled), and the risk that PAD will be used beyond a narrow group of terminally ill individuals. Statutes in the United States have been drafted with these concerns in mind in an effort to mitigate the possible risks of PAD while still providing individuals with access. There seems to be a shift in attitudes towards PAD. Currently four states statutorily permit PAD and it is being discussed by multiple legislatures across the country. There also seems to be a shift in medical practice as demonstrated by a 2015 survey that showed for the first time that more than half of physicians surveyed favored medical assistance in dying. PAD is a deeply personal choice. The question is whether more states will authorize the practice and, if so, what safeguards will be put in place to ensure the practice is not misused and remains consistent with prevailing social and ethical thought

Forced Migration, The Human Face of a Health Crisis

Nearly 60 million refugees, asylum-seekers and internally displaced persons (IDPs) fled their homes in 2014, predominately from war-torn Syria, Afghanistan and Somalia. The global response to assisting this vulnerable group has been wholly incommensurate with the need given the profound health hazards faced by forced migrants at each stage of their journey. The majority of forced migrants are housed in lower-income countries that do not have the infrastructure to assist the significant numbers of individuals who are crossing their borders and the humanitarian organizations who seek to assist in the response are grossly underfunded and under-resourced. Countries have varying responsibilities to protect different classes of forced migrants based in international law, however there are significant gaps in existing agreements, leaving many individuals without protection or hope of assistance. There is a need to strengthen existing international agreements to ensure that all classes of forced migrants are entitled to protection and to ensure the enforceability of existing agreements where governments refuse to honor their existing obligations
