The influence of pH was further validated by observations in a field experimentation plot where different N forms were applied. In order to address this, a regression equation was formulated that incorporated NH3, NO2 and bark pH to produce a predictive model that could potentially be used to evaluate site condition with respect to atmospheric N pollution, as defined by the combined effect of NH3 and NO2. Investigations into the biochemistry of an indicator species identified that rates of phosphomonoesterase (PME) activity were higher in N sensitive species than N tolerant ones.

A total of 21 invited international experts in the responsible gambling field participated in all three phases. A total of 75 performance indicators were outlined and assigned to six categories: (1) criteria of content, (2) modelling, (3) qualification of trainer, (4) framework conditions, (5) sustainability and (6) statistical indicators. Nine of the 75 indicators were rated as very important by 90 % or more of the experts.

The outsourcing of human interaction to algorithms has other implications as well. A person of color who regularly sees 10 20 empty taxis go by before finding one to stop for them, while white people nearby have no such problem, has at least circumstantial evidence he or she is being discriminated against in an illegal way. In contrast, a person who is waiting for an Uber never their would be driver at all.

Of the 7,382 students who took the i Ready exam in the fall of 2019 and fall of 2020, the majority in kindergarten through second grade, students performed on average at 105% of the expected learning growth in math, and at 130% in reading, said Jim Rigg, superintendent of the Archdiocese of Chicago Catholic schools.The study found schools with predominantly white students who took the exam lost an average of one to three months of learning during spring 2020 COVID 19 school closures, and schools with predominantly Black and Latino students fell further behind, losing three to five months, Rigg said.Based on analysis of data from the Curriculum Associates i Ready platform, the study also found that students in the sample learned only 67% of the math and 87% of the reading that grade level peers would typically have learned by the fall of 2020, he said.”For me, our results reflect the rapid move to quality virtual learning in the spring, followed by our in person instruction resuming this fall,” Rigg said, adding that around 80% of students are back in the classroom, with 20% selecting the remote learning option.”We don’t engage students in high stakes testing, but periodic assessments are helpful to our teachers so they can look at each student’s knowledge and growth, and understand how they can support them in the classroom, and help them reach their goals,” Rigg said.Candice Usauskas, principal of St. Mary Star of the Sea School, in the city’s West Lawn neighborhood, said she is pleased, but not surprised, that her students 95% Latino and 75% English language learners performed well on their recent i Ready assessments.Principal Candice Usauskas is pictured at St. Mary Star of the Sea School in Chicago’s West Lawn neighborhood on Feb.
