Central Argument

This article traces the development of acoustic navigation media, or “sonar,” in the first half of the twentieth century, focusing on the relationships forged between underwater sound, electric media, and new techniques of listening. The central argument is that sonar shaped, and was shaped by, the expansion of warfare and capital underwater, and that this expansion came to be conceptualized by nautical organizations as dependent upon the control of underwater sound. Through analysis of key episodes in the conquest of subsea space, the author explores scientific, military, and commercial efforts to sense underwater objects and demonstrates how these efforts helped reconceptualize oceanic water as a component of undersea acoustic media and led to the material reorganization of the ocean’s acoustic field. Cet article retrace le développement de médias acoustiques de navigation ou <> dans la première moitié du vingtième siècle en mettant l’accent sur les rapports créés entre les sons sous-marins, les médias électriques et les nouvelles techniques d’écoute. L’argument central de l’article est qu’il y a eu une influence réciproque entre le sonar et l’expansion sous-marine de la guerre et du capital, et que les organisations nautiques ont commencé à concevoir cette expansion comme nécessitant le contrôle des sons sous-marins. Au moyen d’une analyse d’épisodes clés dans la conquête de l’espace sous-marin, l’auteur explore les efforts scientifiques, militaires et commerciaux pour repérer les objets sous l’eau et démontre comment ces efforts ont aidé à réaliser une nouvelle conception de l’eau océanique comme composante des médias acoustiques sous-marins, menant à une réorganisation matérielle du champ acoustique de l’océan.

Diagnostic Work

But Hertz’s suggestions did not address his original “small metaphysics” conflicts in a credible manner. The alternative resolution that material scientists currently favor supplies an alternative paradigm upon which this book will later elaborate. To this end, the present chapter reviews the intellectual circumstances that Hertz confronted and why they were important to him. He displayed a keen eye for delicate detail in his diagnostic work, in a manner that should serve as a sterling model of conceptual detective work whenever it is wanted. But the depth of his insights has been frequently misunderstood by later generations, largely due to a greatly diminished form of “classical mechanics” that became popular in the twentieth century because of the parochial requirements of quantum theory. Within this reduced setting, Hertz’s motivating problems disappear, not because they have been solved, but because they have been ignored. As an aftereffect, many philosophers writing today confidently believe that they understand what “the worlds of classical mechanics are like,” although these rash presumptions embody a significant degree of simplistic misrepresentation. The present chapter outlines the forgotten background required to appreciate Hertz’s conceptual puzzles as he confronted them. These details are not required for the central argument of the book, but they nicely illustrate the natural contexts from which “small metaphysics” puzzles characteristically emerge within a gradually evolving discourse.

Resumen: Este texto explora la ambivalencia en la producción estructural y discursiva de las posiciones de clase de migrantes que han circulado entre Líbano, Siria y México a lo largo del siglo veinte. Su argumento central es que la inscripción de su subalternidad como sujetos del mandato francés sobre el Mashreq, durante la primera mitad del siglo veinte, ha sido constitutiva de su acceso a una posición privilegiada en el contexto mexicano.Palabras clave: Mashreq, México, Francia, subalternidad, patronazgo. Abstract: This paper explores the ambivalence in the structural and discursive production of the class positions of migrants that have circulated between Lebanon, Syria and Mexico throughout the twentieth century. Its central argument is that the inscription of their subalternity as subjects of the French mandate on the Mashreq during the first half of the twentieth century has constituted their access to a privileged position in the Mexican context.Key words: Mashreq, México, France, Subalternity, Patronage.

The Way

This book has discussed new techniques and methods to address the societal challenges we face. These new approaches change the way policy is framed. The book is an attempt to provide a new compass for policy discussions. This chapter discusses why the complexity frame matters; the evaporation of the optimism that existed in the twentieth century about our ability to deal with major societal challenges; the need for the government to create an ecostructure conducive to allow people the institutional space to self-organize in new ways to solve social problems; and how the complexity policy frame encourages individuals on all sides to be civil.

Changing Attitudes

The Introduction situates David Jones’s work as a poet–artist within the broader currents of high and late modernism, particularly within the context of a tradition of medievalism in twentieth-century poetry. It draws on Alexander Nagel’s conception of the medieval modern to show how Jones approaches the culture and history of the early Middle Ages as a form of live material open to play and adaptation. The Introduction also reframes our understanding of David Jones’s perception of himself as Anglo-Welsh in relation to changing attitudes to early medieval Welsh (Celtic) and English (Anglo-Saxon/Teutonic) history over the course of his lifetime. This discussion introduces the monograph’s central argument: as a poet of the medieval modern, Jones plays with and reworks early medieval English histories, narratives, and artefacts in order to challenge the singularity and exceptionalism of an ‘Anglo-Saxon’ canon.

Acoustic Impact

The paper presents a modeling of the acoustic field emitted by a rig tender located offshore exploration in the Black Sea. Are presented measuring system, experimental context, the types of noise that participate in the overall noise budget and the conditions in which measurements were made, also are mentioned and the project established through were measured the parameters and were defined devices which these measurements were made. Measurement system used is adaptable, allowing dynamic measurements and operative analysis of the acquired data. Measurement methodology was determined by an acoustic project, which was set to be purchased both: sizes and ways of interpreting them. Modeling acoustic field shows that the maximum acoustic impact area, below 120 dB re 1μPa criterion (proposed and accepted by Marine Directive) was extended to 3-5Km distance around the ship. It is expected to produce adverse effects on the marine habitat and on the underwater life.

AbstractIn American Creationism, Creation Science, and Intelligent Design in the Evangelical Market, Benjamin Huskinson presents a close examination of the two main American sociopolitical movements launched in opposition to evolution during the second half of the twentieth century: creation science and intelligent design. Despite a failure of a central argument and a handful of errors, the book is a welcome and valuable interrogation of the stereotypes of American creationism.
