How did Canadian border officers come to think of themselves as a "police of the border"? This book tells the story of the shift to law enforcement in Canadian border control. From the 1990s onward, it traces the transformation of a customs organization into a border-policing agency. Border Frictions investigates how considerable political efforts and state resources have made bordering a matter of security and trade facilitation best managed with surveillance technologies. Based on interviews with border officers, ethnographic work carried out in the vicinity of land border ports of entry and policy analysis, this book illuminates features seldom reviewed by critical border scholars. These include the fraught circulation of data, the role of unions in shaping the border policy agenda, the significance of professional socialization in the making of distinct generations of security workers and evidence of the masculinization of bordering. In a time when surveillance technologies track the mobilities of goods and people and push their control beyond and inside geopolitical borderlines, Côté-Boucher unpacks how we came to accept the idea that it is vital to deploy coercive bordering tactics at the land border. Written in a clear and engaging style, this book will appeal to students and scholars in criminology, sociology, social theory, politics, and geography and appeal to those interested in learning about the everyday reality of policing the border.

The built environment along the U.S.-Mexico border has long been a hotbed of political and creative action. In this volume, the historically tense region and visually provocative margin—the southwestern United States and northern Mexico—take center stage. From the borderlands perspective, the symbolic importance and visual impact of border spaces resonate deeply. In Border Spaces, Katherine G. Morrissey, John-Michael H. Warner, and other essayists build on the insights of border dwellers, or fronterizos, and draw on two interrelated fields—border art history and border studies. The editors engage in a conversation on the physical landscape of the border and its representations through time, art, and architecture. The volume is divided into two linked sections—one on border histories of built environments and the second on border art histories. Each section begins with a “conversation” essay—co-authored by two leading interdisciplinary scholars in the relevant fields—that weaves together the book’s thematic questions with the ideas and essays to follow. Border Spaces is prompted by art and grounded in an academy ready to consider the connections between art, land, and people in a binational region.

This book demonstrates how to control mechanisms of contact mechanics, heat generation and transfer, friction, noise generation, lubrication, and surface damage due to mechanical and thermal variables. Friction and Lubrication in Mechanical Design reviews various classical and new tribology problems beginning with history and ending with numerical optimization and examples, simplifies access to information for predicting and preventing friction and wear, and provides a useful tool for everyone involved in mechanical design, or in machinery monitoring.

This book aims to understand the processes and outcomes that arise from frictional encounters in peacebuilding, when global and local forces meet. Building a sustainable peace after violent conflict is a process that entails competing ideas, political contestation and transformation of power relations. This volume develops the concept of ‘friction’ to better analyse the interplay between global ideas, actors, and practices, and their local counterparts. The chapters examine efforts undertaken to promote sustainable peace in a variety of locations, such as Cambodia, Sri Lanka, Afghanistan, and Sierra Leone. These case analyses provide a nuanced understanding not simply of local processes, or of the hybrid or mixed agencies, ideas, and processes that are generated, but of the complex interactions that unfold between all of these elements in the context of peacebuilding intervention. The analyses demonstrate how the ambivalent relationship between global and local actors leads to unintended and sometimes counterproductive results of peacebuilding interventions. The approach of this book, with its focus on friction as a conceptual tool, advances the peacebuilding research agenda and adds to two ongoing debates in the peacebuilding field; the debate on hybridity, and the debate on local agency and local ownership. In analysing frictional encounters this volume prepares the ground for a better understanding of the mixed impact peace initiatives have on post-conflict societies. This book will be of much interest to students of peacebuilding, conflict resolution, security studies, and international relations in general.

This book describes for the first time a simulation method for the fast calculation of contact properties and friction between rough surfaces in a complete form. In contrast to existing simulation methods, the method of dimensionality reduction (MDR) is based on the exact mapping of various types of three-dimensional contact problems onto contacts of one-dimensional foundations. Within the confines of MDR, not only are three dimensional systems reduced to one-dimensional, but also the resulting degrees of freedom are independent from another. Therefore, MDR results in an enormous reduction of the development time for the numerical implementation of contact problems as well as the direct computation time and can ultimately assume a similar role in tribology as FEM has in structure mechanics or CFD methods, in hydrodynamics. Furthermore, it substantially simplifies analytical calculation and presents a sort of “pocket book edition” of the entirety contact mechanics. Measurements of the rheology of bodies in contact as well as their surface topography and adhesive properties are the inputs of the calculations. In particular, it is possible to capture the entire dynamics of a system – beginning with the macroscopic, dynamic contact calculation all the way down to the influence of roughness – in a single numerical simulation model. Accordingly, MDR allows for the unification of the methods of solving contact problems on different scales. The goals of this book are on the one hand, to prove the applicability and reliability of the method and on the other hand, to explain its extremely simple application to those interested.

Indeed, where crimes are committed, careless perpetrators will invariably leave behind the critical pieces of evidence most likely in the form of fingerprints n
