Описание: Manufactured Insecurity is the first book of its kind to provide an in-depth investigation of the social, legal, geo-spatial, and market forces that intersect to create housing insecurity for an entire class of low-income residents. Drawing on rich ethnographic data before, during, and after mobile home park closures and community-wide evictions in Florida and Texas, the two states with the largest mobile home populations, Manufactured Insecurity forces social scientists and policymakers to respond to a fundamental question: how do the poor access and retain secure housing in the face of widespread poverty, deepening inequality, and scarce legal protection? The book makes important contributions to urban sociology, housing studies, public policy, planning, social inequality, amongst others, and provides a broader understanding of poverty and social welfare in the U.S. today.

Описание:
Additive and Traditionally Manufactured Components: A Comparative Analysis of Mechanical Properties looks at the mechanical properties of materials produced by additive manufacturing (AM) and compares them with conventional methods. Since the production of objects by AM techniques can used in a broad array of materials, the alloys presented are the ones most commonly produced by AM - Al alloys, Ti alloys and steel. The book explores the six main types of techniques: Fused Deposition Method (FDM), Powder Bed Fusion (PBF), Inkjet Printing, Stereolithography (SLA), Direct Energy Deposition (DED) and Laminated Object Manufacturing (LOM), and follows with the techniques being utilized for fabrication.
Testing of AM fabricated specimens, including tension, compression and hardness is included, along with a comparison of those results to specimens obtained by conventional fabrication methods. Topics covered include static deformation, time dependent deformation (creep), cyclic deformation (fatigue) and fracture in specimens. The book concludes with a review of the mechanical properties of nanoscale specimens obtained by AM.
Описание: For eight days in March 1970, over 200,000 postal workers staged an illegal "wildcat" strike-the largest in United States history-for better wages and working conditions. Picket lines started in New York and spread across the country like wildfire. Strikers defied court injunctions, threats of termination, and their own union leaders. In the negotiated aftermath, the U.S. Post Office became the U.S. Postal Service, and postal workers received full collective bargaining rights and wage increases, all the while continuing to fight for greater democracy within their unions.
Using archives, periodicals, and oral histories, Philip Rubio shows how this strike, born of frustration and rising expectations and emerging as part of a larger 1960s-1970s global rank-and-file labor upsurge, transformed the post office and postal unions. It also led to fifty years of clashes between postal unions and management over wages, speedup, privatization, automation, and service. Rubio revives the 1970 strike story and connects it to today's postal financial crisis that threatens the future of a vital 245-year-old public communications institution and its labor unions.
