This study estimates the effect of Medicare Advantage (MA) payments and State Medicaid policies on the choice by Medicaid eligible Medicare beneficiaries to either join a MA plan, remain in the fee-for-service (FFS) and enroll in Medicaid (dually enrolled), or remain in FFS Medicare without joining Medicaid. Individual plan choice was modeled using a multinomial logit. The sample includes Medic...

A long-standing question in the planetary sciences asks what the Earth is made of. For historical reasons, volatile-depleted primitive materials similar to current chondritic meteorites were long considered to provide the `building blocks' of the terrestrial planets. But material from the Earth, Mars, comets and various meteorites have Mg/Si and Al/Si ratios, oxygen-isotope ratios, osmium-isoto...

The goals of most of the organisations are achieving their sustainable competitive advantage (CA) challenges. One of the organizational initiatives is to invest appropriate information infrastructures. However, organisations may face difficulties to select effective information infrastructures in their respective situations to achieve CA from elusive information. This paper is to connect the In...

With nearly 30 percent of Medicare beneficiaries opting to enroll in Medicare Advantage (MA) plans instead of fee-for-service Medicare, it's safe to say the MA program is quite popular. The Centers for Medicare & Medicaid Services (CMS) administers a Star Ratings program for MA plans, which offers measures of quality and service among the plans that are used not only to help beneficiaries choos...

Security of a modern block cipher is commonly measured in terms of its resistance to known attacks. While the provable security approach to block ciphers dates back to the first CRYPTO conference (1981), analysis of modern block cipher proposals typically do not benefit fully from this besides the proof of security for DESX by Kilian and Rogaway, and recent work on the notions of PRP-RKA initia...

While originally developed by Merton to explain advancement in scienti…c careers, cumulative advantage is a general mechanism for inequality across any temporal process (e.g., life course, family generations) in which a favorable relative position becomes a resource that produces further relative gains. We show that the term "cumulative advantage" has come to have multiple meanings in the socio...

biomedical datasets usually include a large number of features relative to the number of samples. however, some data dimensions may be less relevant or even irrelevant to the output class. selection of an optimal subset of features is critical, not only to reduce the processing cost but also to improve the classification results. to this end, this paper presents a hybrid method of filter and wr...

influences of three prevalent mass transfer models, on modeling of cavitation, are investigated numerically. two models of singal and zwart are implemented in an open source code, open foam, while the kunz model is available for cavitation modeling. each model is used to flow simulation through a venturi. volume of gas fraction, in the specified sections of conduit, is compared to experimental ...
