"e;Come Watch the Nighttime Breathe "e; is the first novel in a series written by Jeff Gray that follows a young man named Tristan Wallace as he comes of age and begins his journey to learn the meaning of life and more specifically - the meaning of his life. Tristan was born and raised in a small, Midwest town in the 1970's by a middle-class family, enriched in Catholic values. His safeguarded upbringing never allowed him to adapt properly. As a result, as Tristan comes of age, his desire to gain understanding on the meaning of life and his meaning in life is raised by more than just curiosity and desire, it is heightened with an inner torment. Follow along as his journey begins in this captivating novel. As Tristan grows, ages, and seeks to forge his own path, he is influenced by Catholicism, inspired by Buddhism, yet tormented by a restlessness from deep within him. By chance, Tristan becomes acquainted with four rebellious and reckless men. Unbeknownst to them, they will serve as his life's guides. The night comes alive, these men introduce Tristan to a new world, his curiosity is captured, and the journey begins to drift from the path of Buddha, and he ventures down the paths seldom traveled - paths that are well hidden within the shadows of the night, filled with alcohol, forbidden desires, exploration, and sex.

Models have become essential for dealing with the numerous aspects involved in developing and maintaining complex IT systems. Models allow capturing of the relevant aspects of a system from a given perspective, and at a precise level of abstraction. In addition to models, the transformations between them are other key elements in model-driven engineering. Model transformations allow the de?nition and implementation of the operations on models, and also provide achainthatenablestheautomateddevelopmentofasystemfromitscorrespo- ing models. Furthermore, model transformations may be realized using models, and are, therefore, an integral part of any model-driven approach. There are already several proposals for model transformation speci?cation, implementation and execution, which are beginning to be used by modeling practitioners. However, model transformations need specialized support in s- eral aspects in order to realize their full potential. The problem goes beyond having speci?c languages to represent model transformations; we also need to understandtheirfoundations,suchasthekeyconceptsandoperatorssupporting those languages, their semantics, and their structuring mechanisms and pr- erties (e. g. , modularity, composability and parametrization). In addition, model transformations can be stored in repositories as reusable assets, where they can be managed, discovered and reused. There is also a need to chain and combine model transformations in order to produce new and more powerful transfor- tions, and to be able to implement new operations on models. Finally, model transformations need methodology support, i. e. , they need to be integrated into software development methodologies supported by appropriate tools and en- ronments. These issues and concerns de?ne the focus of these proceedings.

Jeff Gray won the Distinguished Flying Medal in command of a Lancaster bomber. After the war he flew the York, Hermes, Stratocruiser, Comet 4, and VC10. In this beautifully written memoir he takes the reader from agricultural work in rural Scotland to a Lancaster over Berlin, and on to the challenges of airline flying in the post-war years.
