An intuitive method is presented for detecting pseudosymmetries in Z' > 1 cases as a complement to well-proven strategies already available in the literature. It is based in the simple idea that the mid-points between equivalent atoms in symmetrically related mol­ecules are disposed according to simple well-known patterns, which are easily recognizable by optical inspection. A number of Z' = 4 cases in the literature are analyzed, which allows some of the potentialities of the method to be revealed.

The crystal structures of caesium di­hydrogen arsenate(V) bis­[tri­hydrogen arsen­ate(V)], Cs(H2AsO4)(H3AsO4)2, ammonium di­hydrogen arsenate(V) tri­hydrogen arsenate(V), NH4(H2AsO4)(H3AsO4), and dilithium bis­(di­hydrogen phosphate), Li2(H2PO4)2, were solved from single-crystal X-ray diffraction data. NH4(H2AsO4)(H3AsO4), which was hydro­thermally synthesized (T = 493 K), is homeotypic with Rb(H2AsO4)(H3AsO4), while Cs(H2AsO4)(H3AsO4)2 crystallizes in a novel structure type and Li2(H2PO4)2 represents a new polymorph of this composition. The Cs and Li compounds grew at room temperature from highly acidic aqueous solutions. Li2(H2PO4)2 forms a three-dimensional (3D) framework of PO4 tetra­hedra sharing corners with Li2O6 dimers built of edge-sharing LiO4 groups, which is reinforced by hydrogen bonds. The two arsenate compounds are characterized by a 3D network of AsO4 groups that are connected solely via multiple strong hydrogen bonds. A statistical evaluation of the As—O bond lengths in singly, doubly and triply protonated AsO4 groups gave average values of 1.70 (2) Å for 199 As—OH bonds, 1.728 (19) Å for As—OH bonds in HAsO4 groups, 1.714 (12) Å for As—OH bonds in H2AsO4 groups and 1.694 (16) Å for As—OH bonds in H3AsO4 groups, and a grand mean value of 1.667 (18) Å for As—O bonds to nonprotonated O atoms.

Los Angeles Unified's arts education leaders took steps to renew long-dormant community partnerships with arts organizations Wednesday, part of an effort to revitalize arts education in the nation’s second largest school district. 

At the Los Angeles Cathedral in downtown L.A., the district's new arts ed director, Rory Pullens, held his first meeting with community arts organizations. More than 100 people representing several dozen groups attended the event.

Pullens outlined the district's arts plans and how community partners can help boost the arts for students.

“Guess what," Pullens said, getting a round of applause with cheers of support from some of the attendees. "We're back."

Pullens lauded the district's recent announcement clearing the way for arts funding for low-income students, and pointed to new allocations this year that helped some of the district's schools purchase items like art supplies.

He also said the district is working on a school survey to create an arts equity index that will change the way the district allocates arts funds. The index would measure how well schools are providing arts instruction and arts access to students. Originally planned for release last year, the index is now expected next month.

But Pullens also painted a grim picture of the district’s current arts offerings. He said about a third of the district's middle schools currently offer little or no exposure to the arts. Some of the district’s students can go through both elementary and middle school without taking a single arts class, he said. Because of gaps in arts instruction, students who start learning an instrument in elementary school, for example, might not have classes to continue music study in their middle or high schools.

Pullens further talked about widespread budget problems, but took district leaders to task for failing to restore arts funding to the budget as the recession eased.

He said the arts education branch is still facing a deficit. Superintendent Ramon Cortines told reporters recently that the district as a whole is looking at a $160 million shortfall heading into the 2015-2016 school  year.

Despite the mixed funding news, for many in attendance, the meeting marked a positive shift in the district's arts strategy. Some groups currently serve as partners with the district, but the gathering was the first major effort in several years to reach out to organizations with the aim of restoring arts in the schools.

Jay McAdams, the executive director of 24th Street Theatre, said he remembered a few years back when the district emailed a cease-and-desist letter calling for an end to all arts partnership programs. He saw Wednesday's meeting as a major turnaround. 

"This is just a real breath of fresh air. There’s hope, there’s hope for first time in a long time for arts," he said.

In a May 5 research note, analyst John Freeman reported that Raymond James increased its target price on Parsley Energy, Inc. (PE:NYSE) after it posted its Q1/20 numbers.

Raymond James' new target price on Parsley is $12 per share, up from $11. The Texas-based energy company's stock is trading now at about $9.38 per share.

Freeman reviewed and commented on Parsley's Q1/20 results. The company "delivered modest EBITDA and earnings per share beats relative to the Street" due to oil pricing," Freeman pointed out.

Production was relatively in line at 126,600,000 barrels of oil per day (126.6 MMbbl/d), which was 1% higher than consensus' forecast but 1% below Raymond James' estimate. Total production was 1% above the Street's projection but 3% below Raymond James' forecast.

"The performance on the quarter was encouraging, however, the highlight from earnings was the significant reduction in 2020 capex (down from about $1 billion to less than $700 million)," Freeman commented.

Capex, "a welcome surprise," Freeman wrote, came in 5% and 7% lower than the investment bank and the Street's estimates, respectively. Opex was 3% under Raymond James' projection

Moreover, Parsley's related maintenance capital needs were greatly below expectations as well, indicating that Parsley made capital efficiency gains during the period.

"We were pleasantly surprised that Parsley is able to maintain in line Q4/20 oil volumes (about 115 MMbbl/d) on a capital program that's about $300 million/30% below the Street," added Freeman.

Looking forward, Raymond James modeled a base case, or stable scenario for Parsley, that implies a West Texas Intermediate oil price of about $30 a barrel and Parsley having four to five rigs and one to two crews operating. In that scenario, Parsley would produce about 117 MMbbl/d in 2020 and 115 MMbbl/d in 2021.

Capex would amount to about $678 million in 2020, dropping to $598 million in 2021.

Free cash flow would be about $300 million in 2020, which coincides with Parsley's guidance of $300M plus, and increasing to $370 million in 2021.

Raymond James has an Outperform rating on Parsley Energy.
