Moderate emissions grandfathering

Emissions grandfathering holds that a history of emissions strengthens an agent’s claim for future emission entitlements. Though grandfathering appears to have been influential in actual emission control frameworks, it is rarely taken seriously by philosophers. This article presents an argument for thinking this an oversight. The core of the argument is that members of countries with higher historical emissions are typically burdened with higher costs when transitioning to a given lower level of emissions. According to several appealing views in political philosophy (utilitarianism, egalitarianism, prioritarianism, and sufficientarianism) they are therefore entitled to greater resources, including emission entitlements, than those in similar positions but with lower emissions. This grandfathering may play an especially important role in allocating emission entitlements among rich countries

A framework for luck egalitarianism in health and healthcare

Several attempts have been made to apply the choice-sensitive theory of distributive justice, luck egalitarianism, in the context of health and healthcare. This article presents a framework for this discussion by highlighting different normative decisions to be made in such an application, some of the objections to which luck egalitarians must provide answers and some of the practical implications associated with applying such an approach in the real world. It is argued that luck egalitarians should address distributions of health rather than healthcare, endorse an integrationist theory that combines health concerns with general distributive concerns and be pluralist in their approach. It further suggests that choice-sensitive policies need not be the result of applying luck egalitarianism in this context

Symmetric motifs in random geometric graphs

We study symmetric motifs in random geometric graphs. Symmetric motifs are subsets of nodes which have the same adjacencies. These subgraphs are particularly prevalent in random geometric graphs and appear in the Laplacian and adjacency spectrum as sharp, distinct peaks, a feature often found in real-world networks. We look at the probabilities of their appearance and compare these across parameter space and dimension. We then use the Chen-Stein method to derive the minimum separation distance in random geometric graphs which we apply to study symmetric motifs in both the intensive and thermodynamic limits. In the thermodynamic limit the probability that the closest nodes are symmetric approaches one, whilst in the intensive limit this probability depends upon the dimension.Comment: 11 page

The Effect of Wing Tip Floating Ailerons on the Autorotation of a Monoplane Wing Model

The preliminary tests described here were made to determine the extent to which wing tip floating ailerons might be effective in reducing airplane spinning tendencies. The tests showed that initial spinning tendencies and rates of stable spinning could doubtless be reduced by the use of tip floating ailerons on an airplane. It also appears to be desirable to reduce to a minimum the interference between wing and aileron. This would serve to maintain uniformity of action at all angles of attack and enable calculation of the aileron characteristics

An examination of tonal and rhythm curriculum in beginning band method books using Edwin Gordon\u27s learning sequences as a model

This study examines four nationally recognized, beginning band method books to determine whether they adhere to the sequence of skill,tonal content, and rhythm content learning levels developed by Edwin Gordon. Each exercise was examined to determine what skill level is needed to successfully complete the tonal content and the rhythm content of each exercise. The skill level was then ranked according toGordon\u27s skill, tonal content, and rhythm content levels of learning. With Each exercise categorized, the tonal and rhythm curriculum could be compared with Gordon\u27s sequential levels of learning for appropriate sequence. The books studied did not adhere to the sequence of Gordon\u27s Sequential levels of learning. Further study is necessary to provide direct evidence that adherence to Gordon\u27s principles of music learning produces more efficient learning in the band class

On the Very Model of a Modern Major Manager:The Importance of Academic Administrators in Support of the New Pedagogy

The shifting nature of organizational practice within higher education (HE) is such that the contemporary university may, at this stage of its evolution, be completely unrecognizable from the haven of liberal education first described by Cardinal Newman in the early nineteenth century (see, e.g., Senior et al., 2017a). Unlike these small elite institutions, the modern day university is more akin to the pluralistic “multiversity” first described by Charles Kerr in 2001. This model for an effective institute is one that is immediately recognizable as a modern day enterprise with a diverse portfolio of large-scale research activities informing an equally diverse portfolio of large-scale academic programs (Kerr, 2001). One only has to spend a short period of time in any modern day university to realize that Kerr’s model for a university is very much the dominant design within the global HE sector. Such diversity breeds a new psychology in the individuals who govern HE institutes and needs to be considered to ensure that despite its complexity HE is still delivered effectively

Rolling Moments Due to Rolling and Yaw for Four Wing Models in Rotation

This report presents the results of a series of autorotation and torque tests on four different rotating wing systems at various rates of roll and at several angles of yaw. The investigation covered an angle of attack range up to 90 degrees and angles of yaw of 0 degree, 5 degrees, 10 degrees, and 20 degrees. The tests were made in a 5-foot, closed-throat atmospheric wind tunnel. The object of the tests was primarily to determine the effects of various angles of yaw on the rolling moments of the rotating wings up to large angles of attack. It was found that at angles of attack above that of maximum lift the rolling moments on the wings due to yaw (or side slip) from 5 degrees to 20 degrees were roughly of the same magnitude as those due to rolling. There was a wide variation in magnitude of the rolling moment due to yaw angle. The rates and ranges of stable autorotation for the monoplane models were considerably increased by yaw, whereas for an unstaggered biplane they were little affected. The immediate cause of the rolling moment due to yaw is apparently the building up of large loads on the forward wing tip and the reduction of loads on the rearward wing tip
