When two friends at Jackson State University sleep together, the lives of four people take an unexpected turn.

Ideas of justice have traditionally focused on what individuals owe to one another and have drawn our attention to what is considered fair – what one of us owes to another is justly matched by what the other owes to them. However, what does justice require us to do for past and future generations? In Justice Back and Forth, award-winning author Richard Vernon explores the possibility of justice in cases where time makes reciprocity impossible. This “temporal justice” is examined in ten controversial cases including the duty to return historical artifacts, the ethics and politics of parenting, the punishment of historical offences, the right to procreate, and the imposition of constitutions on future citizens. By deftly weaving together discussions on historical redress and justice for future generations, Vernon reveals that these two opposing topics can in fact be used to illuminate each other. In doing so, he concludes that reciprocity can be adapted to serve intergenerational cases.

Simple text and photographs provide examples of back and forth movement, including the pendulum in a clock, a child in a rocking chair, and tree in the wind.

Back and Forth The 100 plus new abstract canvases, carefully reproduced in this book with its unusual format, are the result of one of the most intensive phases of work by Günther Förg in recent years, which took place between Autumn 2008 and Spring 2009. The artist places a sequence of calculated colour fields into a basic grid, which changes from format to format, each individual painting having its own tonal rhythm characterised in turn by a high degree of physical concentration. It is then no coincidence that Rudi Fuchs' linguistically stirring yet acutely observed text discerns an affinity between this work and Piet Mondrians's last und most unusual painting, »Victory Boogie Woogie«. However, the way the palette of colours is organised, supplemented by the structure of each individual colour field, substantially differentiates Günther Förg's endeavour from that his predecessor. In fact it is the free flow of the brushstrokes, the delicate upward and more forceful downward movement alongside the choice of colours, which together propel each individual composition beyond the scope of all previously known abstraction. Or as Rudi Fuch's puts it: »Whether he painted vibrating colour fields, irregular grids comprising raw, fibrous lines, he always had clever interruptive strategies in the implementation. Figuration had to give way in order to release the primordial energy of the brushstroke in its purest form: vigorous abstraction«.

Translated from the French, this book is an introduction to first-order model theory. Starting from scratch, it quickly reaches the essentials, namely, the back-and-forth method and compactness, which are illustrated with examples taken from algebra. It also introduces logic via the study of the models of arithmetic, and it gives complete but accessible exposition of stability theory.

Ethan loves both his mom and his dad, but going back and forth between two homes is hard! Joint custody allows children whose parents are divorced or separated lots of time with each parent, but the actual transitions back and forth can be tough. Children will relate to Ethan's changing feelings as he goes from his dad's house to his mom's house. Parents get nice modeling on how to help their children.
