Some Concerns Regarding Ternary-relation Semantics and Truth-theoretic Semantics in General

This paper deals with a collection of concerns that, over a period of time, led the author away from the Routley–Meyer semantics, and towards proof- theoretic approaches to relevant logics, and indeed to the weak relevant logic MC of meaning containment

Payload installation and deployment aid for Space Shuttle Orbiter spacecraft remote manipulator system

An aid concept known as the PIDA (Payload Installation and Deployment Aid) is presented as a way to assist the RMS (Remote Manipulator System) by relaxing the accuracy required during payload handling in the payload bay. The aid concept was designed and developed to move payloads through a prescribed path between the confined quarters of the payload bay and a position outside the critical maneuvering area of the Orbiter. A description of the design requirements and the modes of operation of the various functions of the deployment and the docking mechanisms are covered

Payload installation and deployment aid for space shuttle orbiter spacecraft remote manipulator system

An aid concept known as the PIDA (Payload Installation and Deployment Aid) is presented as a way to assist the Remote Manipulator System (RMS) by relaxing the accuracy required during payload handling in the payload bay. The aid concept was designed and developed to move payloads through a prescribed path between the confined quarters of the payload bay and a position outside the critical maneuvering area of the Orbiter. An androgynous docking mechanism is used at the payload/PIDA interfaces for normal docking functions that also serves as the structural connection between the payload and the Orbiter, that is capable of being loosened to prevent transfer of loads between a stowed payload and the PIDA structure. A gearmotor driven drum/cable system is used in the docking mechanism in a unique manner to center the attenuator assembly, align the ring and guide assembly (docking interface) in roll, pitch, and yaw, and rigidize the mechanism at a nominal position. A description of the design requirements and the modes of operation of the various functions of the deployment and the docking mechanisms are covered

The Other Debt Crisis

[Excerpt] Much public attention has focused on higher education for the growing debt burdens that students are amassing, the steadily increasing tuition levels, and their impact that these debt burdens, on students’ access to higher education and postgraduate educational, employment and lifestyle options. While students who have amassed six figure debt levels during college are publicized in the press, most graduating students’ debt levels are much smaller

University Endowment Growth: Assessing Policy Proposals

The growth of college and university endowments, particularly those of elite schools, have drawn the attention of policymakers and pundits. Using a decomposition of the growth of endowments between 1991 and 2010 we simulate the effects of three prominent proposed policies had they been implemented in 1991 on endowment payouts through 2010: (1) a minimum spending rule, (2) removing full income tax deductibility of donations, and (3) taxing total endowment sizes beyond a given size. We find that a minimum spending rule increases the average size of endowment payouts for all quartiles of the endowment distribution in nearly all years of the sample period and has a modestly larger relative impact on richer schools. Removing tax deductibility decreases endowment payouts with its effect increasing over time. It has a larger relative impact on schools with smaller endowments than on richer schools
