The Sound of Falling Trees: Integrating Environmental Justice Principles into the Climate Change Framework for Reducing Emissions from Deforestation and Degradation (REDD)

Charitable giving is of great value to society. In particular, wealthy individuals and their families have the ability to make a significant impact on society. Many research papers and wealth briefings try to understand the multi-billion dollar global charitable giving market. These studies have provided valuable insights, but often miss the viewpoint of High Net Worth Individuals (HNWIs). Our comparative research provides a unique perspective on wealthy individuals in France and in the Netherlands. It is the first research to use the same methods in two different countries, which allows us to make solid comparisons. We asked 961 High Net Worth Individuals about their charitable giving behaviour and their knowledge of and interest in impact investing. What causes do our clients value most? How much do they give annually? And how does charitable giving relate to impact investing for the clients? Does the financial return or social return drive individuals to invest with impact? Please join us in this study to explore charitable giving from the giver’s perspective

The Editor\u27s Song

The program of the 2011 Mathfest\u27s opening banquet was MAA-The Musical!\u27 Produced by Annalisa Crannell and starring the MAA Players (active MAA members all), it highlighted activities of the Association and of Mathfest itself. This song represents the journals. It was sung by past editor Frank Farris to the tune of A Wand\u27ring Minstrel I, from Gilbert and Sullivan\u27s the Mikado

Music from Vibrating Wallpaper

Wallpaper patterns have been shown to be decomposable into standing waves of plane vibrations [6]. Previously unexplored are the sounds that arise from these vibrations. The main result of this paper is that each wallpaper type (square, hexagonal, rectangular, generic) has its own distinctive family of pitches relative to a fundamental. We review the method to make wallpaper with wave functions and describe new musical scales for each type, including initial attempts to use the scales: a movie showing vibrations of wallpaper patterns with 3- and 6-fold symmetry inspired a new piece by American composer William Susman, commissioned by the San Jose Chamber Orchestra, Barbara Day Turner, conductor. The piece, “In a State of Patterns,” was premiered on March 25, 2018

An intrinsic construction of Fefferman\u27s CR metric

We construct a conformal class of Lorentz metrics naturally associated with an abstract definite CR structure. If the CR structure is that of a pseudoconvex boundary in Cn we prove that the intrinsically constructed metric is the same as that discovered by Fefferman using a solution to a complex Monge-Ampère equation. The construction presented here relies on formal solutions of a linear equation, dζ = 0, and provides a relatively simple procedure for computing the metric
