An After-School Club That Is Also an Atelier

In 1984, while teaching art to special education students at a South Bronx middle school, the artist and educator Tim Rollins founded the Art and Knowledge Workshop, an after-school program that was part homework club, part atelier. Together with some of his most talented students, Rollins formed the collective Kids of Survival (or K.O.S.) and started making collaborative works that explored literature, art history and themes of race and colonialism. Soon, their pieces — large canvases collaged with pages of books and painted with bold graphics and abstractions — were being shown at the Whitney Biennial and collected by major museums. On Thursday, “Tim Rollins and K.O.S.: Workshop,” the first solo survey of the collective’s work since Rollins’s passing in 2017, opened at Lehmann Maupin gallery.

The day before the opening, Angel Abreu and Rick Savinon, two early collective members who worked with Rollins for more than 30 years, were walking through the gallery to see the work on the walls. “It’s like going through an old photo album,” said Savinon. “You wish some of those people were still here to see it.” Abreu and Savinon were 12 and 15, respectively, in the mid ’80s when they started attending Rollins’s workshop at a studio in the South Bronx. As a teacher, Rollins made an instant impression. “He’d say, ‘This isn’t a glitter art class, we’re not doing construction paper — you’re going to learn about art history,”

Application of the ER method to coarse-graining polymer

Previous studies have demonstrated a scaling relationship between a short-time fast dynamics property, the Debye-Waller factor 〈u²〉, and the relaxation time τ via τ∼exp(u02/〈u2〉) with u02 as an adjustable constant—also called the LM of relaxation—for describing the dynamics of GF liquids (23, 24). 〈u²〉 can be readily obtained from experimental measurements and short-time (on the order of picoseconds) simulations of the materials. In our simulations, the 〈u²〉 is determined from the mean-squared displacement (MSD) 〈r²(t)〉 of the center of mass of monomers of the AA and CG models at around t ≈ 4 ps, corresponding to a caging time scale estimated from our simulations. More recently, Betancourt and co-workers (25) established a more predictive relationship by reducing 〈u²〉 by its value uA2≡〈u2(TA)〉 at the onset temperature T_A for molecular caging and by fixing the prefactor in the τ − 〈u²〉 relation by the observed value of τ at T_A, leading to the relationτ(T)=τAexp[(uA2/〈u2(T)〉)α0/2−1](1)where the exponent α₀ is related to the shape of the free volume (i.e., regions explored by the center of mass of a rattling particle in the fluid). In our recent work, we have applied this relationship, in conjunction with the ER method, to derive the CG potential for ortho-terphenyl (OTP), a small-molecule GF liquid (26). Here, we take this LM relation as the basis of a

The US’s top air-safety regulator has said the plane model involved in Sunday’s Ethiopian Airlines crash, the second such disaster in five months, is safe to fly.

The Federal Administration said in a Continued Airworthiness Notification to the International Community (CANIC) on Monday evening that Ethiopian’s crash, which killed all 157 passengers on board, cannot yet be linked to that Lion Air flight 610, which plunged into the Java Sea 12 minutes after takeoff in October.

“External reports are drawing similarities between this accident and the Lion Air Flight 610 accident on October 29, 2018,” the agency said. “However, this investigation has just begun and to date we have not been provided data to draw any conclusions or take any actions.”

Still, the similarities caused several air carriers and country air-travel regulators, to ground their fleets of 737 MAX 8’s pending further investigation.

US-based carriers notably did not pull the planes from service, with many saying their aircraft are inspected regularly for readiness and safety.

Boeing said in a statement that a technical team would be traveling to the Ethiopian crash site to provide technical assistance in the investigation under the direction of Ethiopian authorities and the US National Transportation Safety Board.

“We extend our heartfelt sympathies to the families and loved ones of the passengers and crew on board, and stand ready to support the Ethiopian Airlines team,” the company said.

One key setpiece in the film is Tyler Durden’s house on Paper Street. This disintegrating, dilapidated residence was created in two parts: an exterior facade constructed in San Pedro, California, and interiors erected on Stage 15 at Fox. “The interior of the Paper Street house was a beautifully built set designed by Alex McDowell,” submits Cronenweth. “It was well into a state of decay, with ceiling pieces coming down and wallpaper and paint peeling, so we had a wide range of textures to work with. We wanted to get a feeling of the old, decrepit house, as well as the deconstructed world the characters were living in. I played the lighting quite down, usually underexposing the walls by 2 to 2  and 1/2 stops, so that you could just barely see into them.” 

Further intrigue was added to the moody visuals through Fincher and Cronenweth’s astute use of compositional detail, and the marrying of texture and tonality to a nearly monochromatic frame. “We played with crosslight, toplight, sidelight and uplight to establish where and what practicals should be placed to bring out the textures of the environment,” Cronenweth explains. “Also, when we’d place a practical, we’d then use an additional concealed raking-source to bring the wall’s texture out and create some contrast with
