When Chicago teachers went on strike in 2012, they highlighted an emergent militance among teachers in the United States. Led by the Caucus of Rank-and-File Educators (CORE), the Chicago Teacher Union (CTU) in the 2010s sought to use the collective bargaining process not only to fight for better salaries and working conditions, but also to dramatically improve the lives of their students through racial justice initiatives and more services such as school nurses and social workers. Other big city unions, some in dialogue with the CTU through the United Caucus of Rank-and-File Educators (UCORE), embarked on similar campaigns. Elsewhere, teachers staged state-wide walkouts. In February 2018, teachers in all of West Virginia’s fifty-five counties went on strike to protest stagnant pay and escalating healthcare costs. Their efforts, which forced a Republican legislature to substantially increase education spending, inspired similar red-state walkouts in the months that followed. Strikes in Oklahoma and Arizona also won major funding hikes, for example. Then, in early 2019, militant teachers walked out in Los Angeles, Oakland, and Denver, and in the fall, the CTU was on strike again, this time with even broader demands than in 2012. Another year of militance might have occurred in 2020, but the global COVID-19 pandemic forced school districts and unions to focus on the immediate public health crisis. Unions pivoted to demanding that districts maintain protocols to ensure teachers, students, and their families were kept safe from the virus.

The world’s cities are expanding at a very fast rate, taking over natural land inhabited by many different animals. It is very important that we monitor the impact this expansion is having on animals in and around our cities. Coyotes are the perfect species to study the effects of urbanization on wildlife, because they are found in both urban and natural environments. We examined how urbanization affects coyotes throughout the Los Angeles area in the United States. We discovered that urbanization influences where different groups of coyotes choose to live and that it also reduces the genetic diversity of coyotes. We should be concerned for the well-being of coyotes because low genetic diversity decreases the ability of any species to fight diseases and deal with other threats. We conclude that the coyote, a species formerly thought to be resistant to human disturbance, is in fact impacted by urbanization.

When the “hard-boiled” private eye of American detective fiction hit the streets in the late 1920s it was not altogether surprising that he should take his complicated path down Californian streets. Not because they were notably meaner than those of big-city crime in New York or Chicago but rather because his essentially private quest for the unravelling of an individual's tortuous truth would find more quarry in the Southern Californian mixingbowl. Each fresh start or re-made life came trailing the spoor of the past. The private eye became expert at detecting the tarnished metal beneath the glittering paint, at offering a wry sympathy to those cheated at the edge of the last frontier. However this “new” society was no more detached from a past that shaped its public form than were its denizens free to make themselves anew. In the hands of one or two writers the mystery was then deepened in ways that replaced the discovery of facts by the probing of relationships between the fixed individual and his forming society. The private eye then required a writer with a public gaze to give him vision.In 1888 an Irish-American boy of Quaker parentage was born in Chicago. After boyhood summers in sleepy Plattsmouth, Nebraska, and the tortured adolescence of a public-school education in Edwardian England the twentyfour-year-old Raymond Chandler, trekking slowly through the Mid-West, arrived in Los Angeles.

The pattern of BSA-Au uptake in vivo by endothelial cells of the venous sinuses (sinusoidal cells) of rat bone marrow has been described previously. BSA-Au conjugates are taken up exclusively in coated pits and vesicles, enter and pass through an “endosomal” compartment comprised of smooth-membraned tubules and vacuoles and cup-like bodies, and subsequently reside in multivesicular and dense bodies. The process is very rapid, with BSA-Au reaching secondary lysosmes one minute after presentation. (Figure 1)In further investigations of this process an isolated limb perfusion method using an artificial blood substitute, Oxypherol-ET (O-ET; Alpha Therapeutics, Los Angeles, CA) was developed. Under nembutal anesthesia, male Sprague-Dawley rats were laparotomized. The left common iliac artery and vein were ligated and the right iliac artery was cannulated via the aorta with a small vein catheter. Pump tubing, preprimed with oxygenated 0-ET at 37°C, was connected to the cannula.
