Abstract In the present paper, we assessed the potential for local wind, solar PV, and energy storage to provide baseload (constant, uninterrupted) power in every county of the contiguous United States. The amount of available capacity between 2020 and 2050 was determined via a least-cost optimization model that took into account changing costs of constituent technologies and local meteorological conditions. We found that, by 2050, the potential exists for about 6.8 TW of renewable baseload power at an average cost of approximately $50 / MWh, which is competitive with current wholesale market rates for electricity. The optimal technology configurations constructed always resulted in over two hours of emergency energy reserves, with the amount increasing as the price of energy storage falls. We also found that, given current price decline trajectories, the model has a tendency to select more solar capacity than wind over time. A second part of the study performed three million simulations followed by a regression analysis to generate an online map-based tool that allows users to change input costs assumptions and compute the cost of renewable baseload electricity in every contiguous US county.

Abstract BACKGROUND Proton therapy for benign and malignant tumors has dosimetric and clinical advantages over photon therapy. Patients in Alberta, Canada are referred to the United States for proton treatment. The Alberta Heath Care Insurance Plan (AHCIP) pays for the proton treatment and the cost of flights to and from the United States (direct costs). This study aimed to determine the out-of-pocket expenses incurred by patients or their families (indirect costs). METHODS Invitation letters linked to an electronic survey were mailed to patients treated with protons between 2008 and 2018. Expenses for flights for other family members, accommodations, transportation, food, passports, insurance, and opportunity costs including lost wages and productivity were measured. RESULTS Fifty-nine invitation letters were mailed. Seventeen surveys were completed (28.8% response rate). One paper survey was mailed at participant request. Nine respondents were from parent/guardian, 8 from patients. All patients were accompanied to the US by a family member/friend. Considerable variability in costs and reimbursements were reported. Many of the accompanying family/friends had to miss work; only 3 patients themselves reported missed work. Time away from work varied, and varied as to whether it was paid or unpaid time off. CONCLUSIONS Respondents incurred indirect monetary and opportunity costs which were not covered by AHCIP when traveling out of country for proton therapy. Prospective studies could help provide current data minimizing recall bias. These data may be helpful for administrators in assessing the societal cost of out-of-country referral of patients for proton therapy.

In this paper, we use publicly available data from the Medical Expenditure Panel Survey - Insurance Component (MEPS-IC) to investigate the effect of Massachusetts' health reform plan on employer-sponsored insurance premiums. We tabulate premium growth for private-sector employers in Massachusetts and the United States as a whole for 2004 - 2008. We estimate the effect of the plan as the difference in premium growth between Massachusetts and the United States between 2006 and 2008—that is, before versus after the plan—over and above the difference in premium growth for 2004 to 2006. We find that health reform in Massachusetts increased single-coverage employer-sponsored insurance premiums by about 6 percent, or $262. Although our research design has important limitations, it does suggest that policy makers should be concerned about the consequences of health reform for the cost of private insurance.

There is a direct relationship between years lived beyond age 65 and the number of individuals diagnosed with dementia, primarily Alzheimer's disease (AD). The occurrence of AD has no socioeconomic, geographical, or ethnic limitations. The problem is worldwide. Its magnitude is demonstrated by the following facts: (a) approximately 6% to 8% of persons 65 years or older have AD, and the prevalence of the disease doubles each 5 years after 60 years of age; (b) 30% of 85-year-old individuals can be expected to have the disease; (c) AD affects an estimated 4 million people in the United States, and is expected to affect approximately 14 million Americans within the next few decades; (d) AD patients average 6 to 10 years of comprehensive treatment from symptom onset to death; (e) AD is the fourth leading cause of mortality among elderly Americans, more than 100,000 each year; (f) caregiver attempts at management of the behavioral and psychological symptoms of AD result in up to 50% developing significant psychological distress themselves; and (g) the cost for the management of AD patients is estimated to be between US $80 billion and US $120 billion annually. Primary care is essential for the appropriate diagnosis and treatment of the complex set of behavioral and psychological symptoms of dementia (BPSD) associated with AD.

Abstract<title> SUMMARY </title>We have gathered here twenty-six writings from the correspondence of Giuseppe Peano, as well as letters by Alexander Macfarlane and Alexander Ziwet.Peano's letters were addressed to Ernesto Cesaro, an important member of the great Italian school of mathematics founded in the second half of the Nineteenth century. In these writings, Peano discusses various topics: Infinitesimal calculus and Barycentric calculus, the «Rivista di Matematica» and the «Formulario» of which he was editor; didactics and a question about Actuarial mathematics. Some of the writings are confidential in nature: in one letter, Peano proposes exchanging his professorial chair with Cesaro's, and hence transferring from Turin to Naples.The letters written by Macfarlane and Ziwet were sent to Peano; they contain, at the request of Cesaro, information concerning university chairs and the cost of living in the United States.
