Immersive, engrossing report on the European refugee crisis A mother puts her children into a refrigerator truck and asks, “What else could I do?” A runaway teenager comes of age on the streets, sleeping in abandoned buildings. A student leaves his war-ravaged country behind because he doesn’t want to kill. Everyone among the thousands of people who come to Europe in search of asylum each year possesses a unique story. But those stories don’t end as they cross into the West. In Lights in the Distance, acclaimed journalist Daniel Trilling draws on years of reporting to build a portrait of the refugee crisis as seen through the eyes of the people who experienced it firsthand. As the European Union has grown, so has a tangled and often violent system designed to filter out unwanted migrants. Visiting camps and hostels, sneaking into detention centers, and delving into his own family’s history of displacement, Trilling weaves together the stories of people he met and followed from country to country. In doing so, he shows that the terms commonly used to define them—“refugee” or “economic migrant,” “legal” or “illegal,” “deserving” or “undeserving”—fall woefully short of capturing the complex realities. The founding story of the EU is that it exists to ensure the horrors of the twentieth century are never repeated. Now, as it comes to terms with the worst refugee crisis since the Second World War, its declared values of freedom, tolerance and respect for human rights are being put to the test. Lights in the Distance is a uniquely powerful and illuminating exploration of the nature and human dimensions of the crisis.

In the first edition of A Practical Guide to Stage Lighting, Steve Shelley cracked open his production book and showed how to prepare a lighting design and create the paperwork needed to mount a production. In the second edition, he pulled back the curtain and showed the methods and processes that go on before the light plot is finalized and ready to go to into the shop, even dealing with cutting the plot in half. In this third edition, Shelley throws the door wide open and shows step-by-step how to construct every lighting system in the Hokey light plot. Combining his diacritical analysis, killer drafting, and analytic use of the Slinky Method and Slinky Calculations, he presents the Periodic Table of Fundamental Lighting Systems and shows the basic methods used to create multi-instrument lighting systems. Highlights include: -Over 100 new topics, including analysis and application of the three categories of collaboration; a detailed examination of production meetings and one-on-one meetings; and meeting checklists with management and the creative team. -Over 50 new illustrations, including Shelley's Periodic Table of Fundamental Lighting Systems; groundplans, sections, and front elevations that illustrate basic system wash configurations for each direction of light. -Analysis, calculation, and step-by-step technical construction of each lighting system in the Hokey light plot. -Explanation of a manufacturer's cut sheet, and how to apply basic formulas to determine the beam size, footcandles, and gel transmission for lighting instruments. -Updated process of pre-programming computer lighting consoles prior to the load-in. -Comprehensive overview of archiving paperwork and softcopy for a production.
