Popular with cinematographer's, the LL-D Filter was designed to help primarily when using film. It requires no exposure compensation, and makes sufficient adjustments to the film to enable the timer to match the color of a properly 85-filtered original. It is not an all-around replacement for the 85. Use it only where needed for exposure purposes, and for subsequently printer-timed work. It is used instead of the #85 in low light scenarios since it does not require the 2/3 stop light loss of the #85.

In this provocative and wide-ranging history, Joel Beinin examines fundamental questions of ethnic identity by focusing on the Egyptian Jewish community since 1948. A complex and heterogeneous people, Egyptian Jews have become even more diverse as their diaspora continues to the present day. Central to Beinin's study is the question of how people handle multiple identities and loyalties that are dislocated and reformed by turbulent political and cultural processes. It is a question he grapples with himself, and his reflections on his experiences as an American Jew in Israel and Egypt offer a candid, personal perspective on the hazards of marginal identities.

Why are workers with identical skills found in both "good" jobs and "bad" jobs? Why are workers who do similar jobs paid differently, contrary to standard competitive theory? Observable differences in workers doing the same job account for only 30 percent of wage variation. In Wage Dispersion, Dale Mortensen examines the reasons for pay differentials in the other 70 percent. He finds that these differentials, or wage dispersion, are largely the result of job search friction (which arises when workers do not know the wages offered by all employers) and cross-firm differences in wage policy and productivity.Mortensen examines previous theoretical explanations for wage dispersion, testing them against data from a Danish matched employer-employee database. He begins by offering a simple one-period model of the problem, then expands this basic model intertemporally to include the role of on-the-job worker search behavior. Following this, he discusses theoretical modifications that offer an explanation for the nature of observed wage dispersion, particularly the shape of cross-firm wage distribution. He then examines the hypothesis that wage policies are determined by profit-maximizing behavior and finds that the Danish data do not support it; he argues that bilateral wage bargaining is the more likely determinant. Finally, he reviews recent work that extends the basic theoretical framework to explain wage dispersion within firms.

The book covers the physical side of colloid science from the individual forces acting between submicron particles suspended in a liquid through the resulting equilibrium and dynamic properties. The relevant forces include Brownian motion, electrostatic repulsion, dispersion attraction, both attraction and repulsion due to soluble polymer, and viscous forces due to relative motion between the particles and the liquid. The balance among Brownian motion and the interparticle forces decides the questions of stability and phase behavior. Imposition of external fields produces complex effects, i.e. electrokinetic phenomena (electric field), sedimentation (gravitational field), diffusion (concentration/chemical potential gradient), and non-Newtonian rheology (shear field). The treatment aims to impart a sound, quantitative understanding based on fundamental theory and experiments with well-characterized model systems. This broad grasp of the fundamentals lends insight and helps to develop the intuitive sense needed to isolate essential features of technological problems and design critical experiments. Some exposure to fluid mechanics, statistical mechanics, and electricity and magnetism is assumed, but each subject is reintroduced in a self-contained manner.

En France comme ailleurs dans le monde, le mot diaspora est récemment entré dans notre vocabulaire courant lorsqu’il s’agit de rendre compte de toute forme de lien existant entre des individus ou des groupes, et les terres, les États, les nations ou les peuples auxquels ils s’identifient. Ce terme fait aujourd’hui partie des lexiques politique, économique, journalistique, juridique mais aussi scientifique et son utilisation ne fait que croître dans chacun de ces domaines, bien au-delà de la seule dimension migratoire, mais aussi bien au-delà de son acception initiale intimement liée à l’histoire du peuple juif.Les mots ont-ils ont une histoire ? Pas vraiment. Leurs usages ont une histoire, qu’il est possible de retracer, y compris sur le très long terme. La Dispersion est la toute première étude académique se donnant pour objectif de suivre la géographie de ces usages, de la création du mot au iiie siècle avant l’ère chrétienne jusqu’à ses transformations les plus récentes et son entrée dans les « bonnes pratiques » mises en avant par des organisations internationales comme la Banque mondiale ou l’Organisation internationale pour les migrations.Cet ouvrage plaide en faveur de l’interdisciplinarité, d’une combinaison inédite entre la sémantique, l’histoire et la sociologie. La socio-sémantique historique permet d’étudier les conditions de possibilité – ou d’impossibilité – de l’émergence des différents usages du mot, de ses appropriations par des groupes sociaux différents, de son succès et de son efficacité croissante. Cette approche a un prix : refuser toute prise de position sur le sens réel du mot diaspora, sur sa véritable définition, au profit d’une cartographie complexe de ses trajectoires.

As a historical and religious term "diaspora" has existed for many years, but it only became an academic and analytical concept in the 1980s and ?90s. Within its various usages, two broad directions stand out: diaspora as a dispersion of people from an original homeland, and diaspora as a claim of identity that expresses a form of belonging and also keeps alive a sense of difference. Between Dispersion and Belonging critically assesses the meaning and practice of diaspora first by engaging with the theoretical life histories of the concept, and then by examining a range of historical case studies. Essays in this volume draw from diaspora formations in the pre-modern Indian Ocean region, read diaspora against the concept of indigeneity in the Americas, reassess the claim for a Swedish diaspora, interrogate the notion of an "invisible" English diaspora in the Atlantic world, calibrate the meaning of the Irish diaspora in North America, and consider the case for a global Indian indentured-labour diaspora. Through these studies the contributors demonstrate that an inherent appeal to globality is central to modern formulations of diaspora. They are not global in the sense that diasporas span the entire globe, rather they are global precisely because they are not bound by arbitrary geopolitical units. In examining the ways in which academic and larger society discuss diaspora, Between Dispersion and Belonging presents a critique of modern historiography and positions that critique in the shape of global history. Contributors include William Safran (University of Colorado Boulder), James T. Carson (Queen's University), Eivind H. Seland (University of Bergen), Don MacRaild (University of Ulster), and Rankin Sherling (Marion Military Institute: the Military College of Alabama).
