The Central Valley Salmonid Story: Six Million Years in the Making

For over six million years, salmon and steelhead (known as salmonids) have returned to the California Central Valley. After swimming under the Golden Gate Bridge and through the San Francisco Bay, adult salmonids swim hundreds of miles up the Sacramento or San Joaquin Rivers. Before dams were built, three out of the five salmonid species swam from the Central Valley into high-elevation, cold-water streams within the Sierra Nevada, southern Cascades, and Coastal Mountain ranges to finish their life cycles. Unfortunately, barriers such as dams cut-off salmonids from their home streams. When salmonid populations decrease, the effects are felt across the ecosystem—everything from microbes to humans feels the disconnection between the rivers and the ocean. Governmental agencies and their partners are teaming up to restore Central Valley salmonid populations by reconnecting them to their habitats and putting them back into high-elevation streams.

L'ipotesi dello spostamento nel suicidio: persona e situazione in psicopatologia

Viene mostrato come l'ostacolo a taluni strumenti suicidari non porti necessariamente a spostarsi su altre modalità letali, esaminando in particolare il caso dell'intossicazione da gas domestico in Gran Bretagna e gli ostacoli per prevenire il salto dal Golden Gate Bridge di San Francisco. Il mancato spostamento sembra caratterizzare anche altri aspetti patologici, quali il gioco d'azzardo, le dipendenze o la criminalità. L'ipotesi dello spostamento è in realtà legata all'errore fondamentale di attribuzione, che privilegia gli aspetti disposizionali rispetto a quelli situazionali. Vengono esaminati bias collegati a questo errore di attribuzione, come la mancata stabilità e coerenza nel tempo e nelle diverse situazioni degli aspetti disposizionali, la mancata coerenza tra atteggiamenti e comportamenti, e gli errori che gli approcci disposizionali inducono nella previsione di compor-tamenti con il variare delle situazioni. Questi bias mettono in discussione il concetto tradizionale di personalità e il suo ruolo nella genesi dei sintomi o nella predizione dei comportamenti, e anche i modelli psicologici tradizionali che prevedono che i comportamenti siano sempre conseguenza degli atteggiamenti della persona. Il ruolo degli aspetti situazionali, specialmente dei cosiddetti "fattori canale", appare importante nella modifica di comportamenti in ambito preventivo e tera-peutico.

A Dream Finds Allies

Chapter 5 examines Headen’s embrace of Henry Wood’s coalition strategy, exploring how he adapted Wood’s model to promote an anti-submarine device he invented during World War I. To promote the device, which refracted light to render submarine chasers invisible, Headen assembled a broad interracial coalition that drew from Chicago’s business, religious, entertainment, political, and academic communities. Included were individuals as diverse as Robert R. McCormick of the Chicago Tribune, for whom Headen worked as a chauffeur; philanthropists Nettie Fowler McCormick and Julius Rosenwald; black orchestra leader Joe Jordan; white banker George Liebrandt; University of Chicago professor Harvey Lemon; white patent lawyer Wilmot C. Hawkins; black minister Archibald J. Carey; and later Golden Gate Bridge constructor Joseph B. Strauss. The chapter documents how this coalition secured an audience for Headen with the U.S. Naval Consulting Board and the British Admiralty’s Board of Invention and Research (after 1918 the Department of Experimental Research, or DER). It also describes subsequent work Headen completed for the British Shipping Ministry, the positive assessment of his device by the DER, and the project’s languishing upon the war’s sudden end.

Golden Gate

William Brown’s Golden Gate is a poetic video essay that reworks footage from 43 movies, spanning eight decades. Through intertitles, repetition, loops and other formal strategies, the film creates an affective and theoretical argument concerning the role of the Golden Gate Bridge in American cinema and American culture more generally. Taking a posthuman approach, Brown considers the bridge not just in terms of its spatial span across the Golden Gate Bay but also as a ‘living, sentient’ entity. This video essay connects films featuring the bridge that deal with the birth of artificial intelligence, autism, alien invasion and the control of woman to suggest how it could represent, if not the end of humanity, then the end of western patriarchal masculinity.

Riesgos industriales y la ingeniería de riesgos

Estimados lectores de la Revista REBI, para su Comité Editorial es un placer hacerle llegar este nuestro cuarto número y volumen 2, en marco de una pandemia que nos ha hecho visualizar al mundo de una manera diferente. El objeto de la revista es ser un medio de difusión de los resultados originales e inéditos de las investigaciones realizadas por profesores, profesionales y estudiantes en las áreas de la ingeniería, tecnología y afines y que proporcionan una eminente contribución al conocimiento científico y tecnológico. Esta difusión cuenta el avance y estado del conocimiento y busca su divulgación y adecuado resguardo. Nuestros lectores y público al que destinamos la revista es principalmente la comunidad científica y académica en Bolivia, América Latina y el mundo. Los riesgos industriales traen diversos efectos en los seres vivos, proceso y productos, los que nos ha hecho visualizar la ingeniería de manera diferente. En este marco, es emblemático la construcción del famoso Golden Gate Bridge (puente colgante la ciudad de San Francisco, USA), construido durante el período de 1933 a 1937. Es emblemático ya que por primera vez se da prioridad a la seguridad de los operarios, comenzando a utilizar lentes y cascos especiales, debido a los vientos que eran sujetos durante su trabajo. Además, para limitar los riesgos de pérdidas de vidas humanas durante su construcción se instaló una red de seguridad. La misma salvó la vida de 19 hombres que, durante su construcción cayeron al vacío. Hasta febrero de 1937, cuando un andamio cae con diez (10) personas y, cuyo peso, la malla no fue capaz de soportar ocasionando un accidente fatal. Un riesgo representa un daño potencial, el cual debe ser limitado para minimizar sus posibles efectos. Actualmente, la Ingeniería de Riesgos es una rama especializada que considera el análisis, diseño y desarrollo de programas de control de riesgos de todo tipo, no sólo los debidos a los procesos industriales, siendo una carrera en auge a nivel global. Para esta carrera existen diferentes ramas que van desde el análisis para la prevención, hasta especializados como riesgos y seguros o riesgos, seguridad y ambiente. En el marco de la pandemia del COVID-19, destaca la función de los ingenieros de estas especialidades que deben garantizar la productividad de los procesos y la salud de los trabajadores y consumidores finales. A ellos y al personal médico, enfermeras y trabajadores que, en general, todos los días

ARCHITECTURAL PLANNING PRINCIPLES OF URBAN BRIDGES RECONSTRUCTION

The bridges and overpasses of the city of Samara are considered, their main characteristics are identifi ed. A brief historical background of the appearance of the fi rst bridges as simple engineering structures is given, the main temporary periods are highlighted. Examples of implemented solutions that characterize the main stages of the history of bridge construction are given: the Hohenzollern Bridge in Cologne, the Millennium Bridge in Gateshead, the Ponte Vecchio Bridge in Florence, the Golden Gate Bridge in San Francisco, the Russian Bridge in Vladivostok, the String Bridge in Jerusalem. The analysis helps to understand how a modern bridge, located in the city building system, aff ects it, complements and enriches it, combines many functions and advanced technologies, and also has architectural expressiveness.
