Under the "More on Philosophies of Copyright" section, I recommended adding the scholarly article by Chinese scholar Peter K. Yu that explains how Chinese philosophy of Yin-Yang can address the contradictions in effecting or eliminating intellectual property laws. One of the contradictions is in intellectual property laws protecting individual rights while challenging sustainability efforts for future generations (as climate change destroys more natural resources.

Below is a short excerpt from the article that details Chinese philosophical thought on IP and sustainability:
"Another area of intellectual property law and policy that has made intergenerational equity questions salient concerns the debates involving intellectual property and sustainable development. Although this mode of development did not garner major international attention until after the 1992 Earth Summit in Rio de Janeiro, the Yin-Yang school of philosophy—which “offers a normative model with balance, harmony, and sustainability as ideals”—provides important insight into sustainable development."

„Und?“, fragt Schmidt und macht eine Kunstpause, „enttäuscht?“
Coincidence that Schmidt shows a journalist Luhmann's zettelkasten in 2015 and asks if they're disappointed?
It's reasonably likely that he'd already read ZKII 9/8,3.

in the article which follows below, there's an explicit mention of this specific zettel, so the question on priority here is closed.
Therefore, we propose that flow and hyperfocus are the same phenomenon. Although we are mindful that just because two phenomena are descriptively similar, they are not necessarily mechanistically identical, there is no evidence to suggest that either flow or hyperfocus are distinct.
Ashinoff and Abu-Akel propose an equivalence between "flow" and "hyperfocus". They mention later in this paper that "flow" is more often used in positive psychology literature whereas "hyperfocus" is more often used in psychiatric literature. Even so, they also qualify that they may just appear to be the same (ie, descriptively similar) while having a different cause (ie, mechanism of action).
Companies are excellent environments for social filtering. Because they sit on large volumes of data and information, going largely unused. Because organisations are a group of people with shared goals and tasks.
This never happened in this way. Another example of how #socsoft became marketing almost exlusively. With the exeception perhaps of async tools like Slack (2013) or Yammer (2008, still exists as part of MS), although filtering is not their point, their users may use it that way. The whole #socsoft for org internal k-work never got much traction. Still a lost opportunity imo. Tools probably need to better fit existing culture/communication styles in org and be internal, but being created as separate place external with its own assumptions.

A multicenter, prospective, randomized, masked, vehicle-controlled pilot fieldstudy
OK, let's break down these terms: * multicenter: the study was conducted studying animals at multiple clinics/locations * prospective: study subjects are enrolled and followed BEFORE the disease or the outcome is observed (in this case the painful procedure/analgesic response. Prospective studies tend to be less prone to bias, compared to retrospective studies (like evaluating historical patient records of prior disase/treatment/outcome). * randomized: enrolled subjects are assigned to treatment or control groups randomly. Randomization can be an effective way to minimize intentional or unintentional bias in a study. For example, in a non-randomized study an investigator might (intentionally or unintentionally) place all of the younger subjects in the control group and the older subjects in the treatment group. Now you have two things that could contribute to a difference between controls and treatments, the actual treatment AND AGE. So if there was an improvement in the treatment group, which thing did it, treatment or age? Randomization reduces the occurrence of biases like that. * masked : this is also called blinded. In masking, one or more categories of study workers are blinded as to whether subjects are in the treatment group or the control group. I'd have to look at the full experimental write-up to know exactly who was blinded, but at a minimum the study workers assessing the analgesia should be blinded as to whether they are observing a treatment, or a control animal. This can be complicated! A vehicle control cat is unlikely to be dysphoric/euphoric, so if I am a study worker and I see a dysphoric cat, I will likely be biased to assume that it has been treated with drug, and that could in turn bias my assessment of its pain. * vehicle control : this is a form of placebo control. the treatment group gets vehicle+drug, the control group gets only vehicle. You will also read about "active control". In this case it is an intramuscular injection of bupe. This allows a comparison between all the things that can interfere with transdermal absorption, and an administration of bupe that bypasses the vagaries of transdermal absorption and lets the investigators know what a more reliably absorbed, roughly equivalent dose, is capable of. Placebo controls and vehicle controls are also related to masking/blinding. In the ideal world, almost no one should know whether a patient got the control treatment or the test treatment, until the study is completed and the data analyzed. This reduces bias in assessing the effect of the treatment. * pilot : a pilot study is an early study, often used to explore dose, timing, effectiveness in a smaller number of animals to aid in designing a larger subsequent study.
EFFECTIVENESS
Remember, the two basic things that FDA requires for approval are 1) actual evidence that establishes the drug is an effective treatment for the specific indications in the application (in this case post operative analgesia in cats) and 2) typical use of the drug is unlikely to cause injury that is disproportionate to the risk that the disease presents. For example, most anticancer drugs may cause injury, but the diseases that they treat have a much greater risk of injury if left untreated. But there would be a much higher expectation of safety in a drug to treat kennel cough, a disease which is rarely fatal and often self-limiting. So here, in this data we'll see studies designed to provide evidence of effectiveness, and studies designed to provide evidence of safety.
ORIGINAL NEW ANIMAL DRUG APPLICATION
This drug is not exactly an earth-shaking discovery. "BuTrans", from the notorious Purdue Pharma (in a legal settlement, Purdue Pharma agreed to disband as a business) was FDA approved for humans in 1981, is a transdermal buprenorphine patch.
Statistical Methods:
Beyond our scope, don't worry about this.
Inclusion
Inclusion and Exclusion criteria are important! Remember, you are trying to keep the treatment group and control group as similar to each other as possible.
Executive Summary
To me, the executive summary (not sure why they call it that!) seems to be pretty dialed-down for a non technical audience. This is a great skill to get better at, although at points the basic language can get a bit confusing
Doses greater than 30 mg/cat appeared to result in lessthan proportional increases in plasma buprenorphine concentrations.
This concept is called dose proportionality, and it is a really handy thing to know. What they are saying here is that beyond a dose of 30mg/cat you lose dose proportionality. This implies that below that dose, if you double the dose you should see approximately a doubling of plasma concentration--That's dose proportionality!
he rate of elimination of buprenorphine transdermal solution is faster thanits rate of absorption from the skin (flip-flop kinetics)
This is a nice & clear explanation of "flip-flop kinetics"! Far more common is the situation in which absorption is fast, compared to the slower elimination. In that far more common scenario, half-life (aka terminal half-life) is driven by clearance. Here, the rate of absorption is so slow that whatever drug is absorbed is quickly distributed and cleared (but of course during that process some drug gets to its CNS targets and binds (tightly!) to them.
Zorbium™ is rapidly absorbed and sequestered into the skin.
Not surprising since bupe is really, really lipophilic.
which meansit doesn’t bind as strongly to the receptor as full agonists
this is an example where oversimplification distorts the facts. "bind as strongly" is not accurate, and it disagrees with "high binding affinity" in the previous paragraph. Bupe does bind with very high affinity to the mu opioid receptor. It is a partial agonist because that tight binding is not capable of causing the conformational change in the receptor that is necessary to produce a maximal receptor response. The ability to fully activate a receptor is not a function of the tightness of binding (if that was the case naloxone, which also binds tightly, would be a full agonist). It is a function of whether the binding induces the 3-d changes in the receptor that cause it to signal its activation to the interior of the cell.

indifference to human drivers
Our week 8 module on Web 2.0 and the gig economy discussed this in more depth, and Barron alludes to this dynamic elsewhere in the article when describing both the typical user of an app like seamless and the typical profile of the gig economy worker who actually delivers their food - I appreciate the critiques of app design and user infantilization he is making here, but the article could have also discussed in more depth how these design choices help these companies to obfuscate and divert attention from the way they impact people besides the consumer. There is a whole class people whose primary interaction with these apps is on the back end- as struggling small business owners dependent on positive yelp reviews, delivery people, and rideshare drivers - maybe that is outside the purview of this article, but it would have been nice to see this angle explored a bit more.

Alloys[edit] Antimony forms a highly useful alloy with lead, increasing its hardness and mechanical strength. For most applications involving lead, varying amounts of antimony are used as alloying metal. In lead–acid batteries, this addition improves plate strength and charging characteristics.[49][59] For sailboats, lead keels are used as counterweights, ranging from 600 lbs to over 8000 lbs; to improve hardness and tensile strength of the lead keel, antimony is mixed with lead between 2% and 5% by volume. Antimony is used in antifriction alloys (such as Babbitt metal),[60] in bullets and lead shot, electrical cable sheathing, type metal (for example, for linotype printing machines[61]), solder (some "lead-free" solders contain 5% Sb),[62] in pewter,[63] and in hardening alloys with low tin content in the manufacturing of organ pipes. Other applications[edit] Three other applications consume nearly all the rest of the world's supply.[48] One application is as a stabilizer and catalyst for the production of polyethylene terephthalate.[48] Another is as a fining agent to remove microscopic bubbles in glass, mostly for TV screens;[64] antimony ions interact with oxygen, suppressing the tendency of the latter to form bubbles.[65] The third application is pigments.[48] Antimony is increasingly being used in semiconductors as a dopant in n-type silicon wafers[66] for diodes, infrared detectors, and Hall-effect devices. In the 1950s, the emitters and collectors of n-p-n alloy junction transistors were doped with tiny beads of a lead-antimony alloy.[67] Indium antimonide is used as a material for mid-infrared detectors.[68][69][70]

Crushed minerals are extracted with hydrochloric acid or sulfuric acid, which converts the insoluble oxides into soluble chlorides or sulfates. The acidic filtrates are partially neutralized with caustic soda to pH 3–4. Thorium precipitates as its hydroxide, and is then removed. The remaining solution is treated with ammonium oxalate to convert rare earths into their insoluble oxalates. The oxalates are converted to oxides by heating. The oxides are dissolved in nitric acid that excludes one of the main components, cerium, whose oxide is insoluble in HNO3. The solution is treated with magnesium nitrate to produce a crystallized mixture of double salts of gadolinium, samarium and europium. The salts are separated by ion exchange chromatography. The rare-earth ions are then selectively washed out by a suitable complexing agent.[

Potassium mines in 3rd world countries.
Most of the antimony mined each year comes from China, which supplies over three-quarters of the world’s total. The remainder is from Russia, South Africa, Tajikistan, Bolivia, and a few other countries, including the United States. Some antimony is produced as a by-product of smelting ores of other metals, mainly gold, copper and silver, in countries such as the United States, Canada, and Australia.
Top antimony producing countries
Antimony is rarely found in its native (as an element) state. Instead, it usually occurs as a compound. The most common minerals of antimony are stibnite, tetrahedrite, bournonite, boulangerite, and jamesonite.
How antimony is found in nature
Antimony is a moderately active element. It does not combine with oxygen in the air at room temperature. It also does not react with cold water or with most cold acids. It does dissolve in some hot acids, however, and in aqua regia. Aqua regia is a mixture of hydrochloric and nitric acids. It often reacts with materials that do not react with either acid separately.
Chemical properties of antimony
Antimony is a silvery-white, shiny element that looks like a metal. It has a scaly surface and is hard and brittle like a non-metal. It can also be prepared as a black powder with a shiny brilliance to it. The melting point of antimony is 630°C (1,170°F) and its boiling point is 1,635°C (2,980°F). It is a relatively soft material that can be scratched by glass. Its density is 6.68 grams per cubic centimeter.
Physical properties of antimony
Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. In addition antimony trioxide is possibly carcinogenic to humans.
Negative health effects of repeated exposure to antimony
Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. It is alloyed with lead or other metals to improve their hardness and strength. A lead-antimony alloy is used in batteries. Other uses of antimony alloys include type metal (in printing presses), bullets and cable sheathing. Antimony compounds are used to make flame-retardant materials, paints, enamels, glass and pottery.

Rehabilitation and restoration approaches can help restore ecosystem services that have been lost due to desertification.
desertification - prevention and restoration
Damage to water sources that residents attribute to mining, as well as increased demand due to population migration to mining sites, reduces communities’ access to water for drinking, washing and cooking. Women, who are primarily responsible for fetching water, are forced to walk longer distances or wait for long periods to obtain water from alternative sources. The dust produced by bauxite mining and transport smothers fields and enters homes, leaving families and health workers worried that reduced air quality threatens their health and environment.
Mining is contaminating our water sources and water is one of the most important things for survival.
In 2002, Molycorp had a problem with its waste disposal at Mountain Pass, when a pipeline leading out to evaporation ponds in the desert burst, spilling radioactive and toxic waste onto the desert floor (Danelski, 2009). The resulting uncovering of past spills, coupled with economic factors, caused the shutdown of Mountain Pass and a complete reworking of their environmental practices. However, the damage was done and the area and surrounding water sources are affected, perhaps permanently.
We need to find a way to prevent pipeline spills because they happen way too frequently and they are horrible for the environment.
Drift mining utilizes horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining utilizes vertical access shafts. Mining in hard and soft rock formations require different techniques.
So different kinds of mining use different tunnel systems, how do we decide which kind is best in each situation?
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices.

Teck officials say the safety and stability of HVC’s tailings damn was not affected in any way and there was no environmental impacts as a result of the incident.
there was no pollution caused because of the mines safety measures.
Stannell says due to freezing, a leak occurred in the water pipeline that services the tailings facility, resulting in approximately 850 cubic meters of process water spewing from the pipeline
cold weather can cause pipe lines the break.
An investigation continues into what led to a large volume of contaminated water being leaked from the Highland Valley Copper Mine near Logan Lake.
The Highland Valley copper mine in Canada leaked polluted water into near by lake.
Cities such as Lubumbashi and Likasi face serious air pollution because of the thousands of trucks that travel to and from the mines throughout the day. Chronic exposure to such dusts can lead to severe lung diseases. Water is unfit for human consumption and agriculture because soil and water in the immediate vicinity of the mines are polluted by discharges of wastewater.
Chile has developed from 1990 to date, a considerable decrease in poverty rates, which fell from 40.5% in 1990 to 8.5% in 2015.
this is a benefit
“It’s very difficult to open a mine in a particular place without destroying the landscapes and livelihoods that were previously there.”
Lithium-ion batteries are key components for most consumer electronics, from cellphones and laptops to electric cars.
the ions in the lithium is the competent that is found in phones.
The governments of Ethiopia and Russia are set to expand business ties on multiple frontiers, ranging from nuclear energy development to Russians investment in mining in Ethiopia.
That's interesting!
the government reported the discovery of large gold deposits in Lege Dimbi, also in Sidamo.
This shows that there was gold in Ethiopia!
Due to its electrical conductivity, copper is used in electronics, cars, and wires. This makes copper critical for highly developed countries.
true stuuff
Developing economies’ copper demand has steadily grown over the last decades, fueling economic and social improvement. By 2011, China already represented 40% of the demand.
Why does China need so much.
Codelco is a state-owned Chilean mining company and the world’s largest copper producer. Based on their annual report and USGS statistics, they produced ~10% of the world’s copper in 2015 and own 8% of global reserves. They are also a large producer of greenhouse gas emissions. Last year, Codelco produced 3,2 t CO2e/millions tmf from both indirect and direct effects, and in 2011 it consumed 12% of the total national electricity supply.
Goddamn they should start recylcling
copper mining significantly contributes to climate change.
Neodymium is chiefly obtained from monazite and bastnasite, where it occurs as an impurity. It is mined in the USA, China, Russia, Australia, and India.
some info about the ore and where it is mined
The Neodymium metal element is initially separated from refined Rare Earth oxides in an electrolytic furnace. The "Rare Earth" elements are lanthanoids (also called lanthanides) and the term arises from the uncommon oxide minerals used to isolate the elements
how neodymium is refined
Although few in number, the multinational mining companies that are earning billion-dollar profits in Zambia have had a massive impact on its environment and people.
The metal is a solid material and metallic gray in color. Furthermore, the metal possess high melting and boiling points. At standard temperature and pressure, cobalt is not readily oxidized, which means it does not easily lose electrons from its surface.
A description of cobalt.
cobalt can be found among the d-block elements, transition metals. It has the chemical abbreviation Co and atomic number 27.
Where to find cobalt on periodic table and cobalt's atomic number.
Monseigneur de Hemptinne watched Yeke people working at Dikuluwe as late as 1924. They worked in the dry season and stopped when the first rains arrived. The mining camp was near a stream where millet could be planted. Women and children collected malachite from the surface, while men used iron picks to excavate pits and shafts, using fire to crack the rocks when needed. The mines were between 10 metres (33 ft) and 15 metres (49 ft) deep with galleries up to 20 metres (66 ft) long. The ore would be sorted and then taken to a nearby stream for concentration before being smelted

The Katanga, or Shaba, copperbelt in the DRC is a belt about 70 kilometres (43 mi) wide and 250 kilometres (160 mi) long

his is the second round of mineral licensing conducted by the Afghan government, which in 2008 gave Metallurgical Corp of China rights to the Aynak copper deposit
They seem to offer up mining contracts very easily.
The country’s economy is completely dependent on mining. Many poor families are completely dependent on their children working the mines. That $9/day is hard for a child to reject
its weird how people are able to exploit these people legally, and if not legally than how have people not made an effort to stop them?
Walt describes how the multibillion-dollar industry, that has made some people outside Africa really really rich, is not known to workers like Lukasa. He just sells his haul to Chinese traders who have seen their profits increase 400% over the last two years.
I wonder if the people at the top of the company even know that this is going on with there "employees"
Cobalt's primary ores are cobaltite (CoAsS) and erythrite (Co3(AsO4)2). Cobalt is usually recovered as a byproduct of mining and refining nickel, silver, lead, copper and iron.
this is where cobalt comes from
Xiamen Tungsten and Xiamen Sanhong Molybdenum would invest more than 2 billion yuan (US$314.13 million) in the surveying and subsequent exploitation of the tungsten ore mine.
The proved reserve of the mine has exceeded Jiangxi's total amount of available tungsten reserves, and has a potential economic value of more than 300 billion yuan (US$47.13 billion).
Elodie is 15. Her two-month-old son is wrapped tightly in a frayed cloth around her back. He inhales potentially lethal mineral dust every time he takes a breath. Toxicity assaults at every turn; earth and water are contaminated with industrial runoff, and the air is brown with noxious haze. Elodie is on her own here, orphaned by cobalt mines that took both her parents. She spends the entire day bent over, digging with a small shovel to gather enough cobalt-containing heterogenite stone to rinse at nearby Lake Malo to fill one sack. It will take her an entire day to do so, after which Chinese traders will pay her about $0.65 (50p). Hopeless though it may be, it is her and her child’s only means of survival.
Personal Learning Environments (PLE) applied to K-12 classroom
personalized mobile learning solutions to create effective learning paths This appears to blend personalized learning and mobile learning. It is prepared by a specific vendor, MagicBox, so they might be assumed to have their own agenda. This page describes some of the affordances of personalized mobile learning, such as the capacity to track and presumably respond to learner preferences. rating 2/5

This should be taught throughout k-12 schooling. Learnng this in college was super helpful but it was taught a little late for me. I know now how to choose sources that present good information but growing up I wouldnt have been able to do that
What K–12 Administrators Should Think About When Integrating Classroom Tech

Evaluation, when it is not asked for, and when it has consequences as it does in school, is a threat. It narrows the mind... it inhibits new learning, new insights, and creative thought—the very processes that some people think school is supposed to promote. -- Peter Gray

Why is it clear to us that it's degrading and objectifying to measure and rank a girl’s physical body on a numeric scale, but we think it’s perfectly okay to measure and rank her mind that way?

what an oak tree actually needs is not your opinion but soil and water and light and air, and what a child needs is love and stories and tools and conversation and support and guidance and access to nature and culture and the world. If a kid asks for your feedback, by all means you can give it; it would be impolite not to. But what we should be measuring and comparing is not our children but the quality of the learning environments we provide for them.
Fifty years ago, the science-fiction writer Philip K. Dick coined a phrase for these “useless objects” that accumulate in a house: “kipple.” In Do Androids Dream of Electric Sheep?, which served as the basis for the movie Blade Runner, he theorized that “the entire universe is moving toward a state of total, absolute kippleization.” Kipple reproduced, Dick wrote, when nobody was around. The ubiquity of mobile devices and the ease of online shopping have made Dick’s prediction come true, with one small tweak: Our kipple does not just multiply on its own, every time we turn away. We grow it ourselves, buying more and more of it, because we can.
However, as admirable as James’ philanthropic efforts are, they are not a solution to the problems in public education.
I don't think James ever claimed he was solving "the problems in public education." How about he's shining a light on ways increased public funding could stimulate public education?

Can an 'Open' Math Curriculum Compete With Commercial Publishers?
Parents and students in the Mountain View school district consider their use of math software called Teach to One to be a failure.
The Mountain View school district apparently budgeted $521,000 to implement and operate this new-fangled math program in two local schools. Had they adequately beta tested the program beforehand, the school district might have discovered that Teach to One teaches math (we’ve found) in a disjointed, erratic, and non-linear fashion that leaves many students baffled and disenchanted with math. The program contains errors in the math it teaches. Parents end up having to teach kids math at home and make up for the program’s deficiencies. And all the while, the math teachers get relegated to “managing the Teach to One program rather than to providing direct instruction” themselves.
Sounds like they would have been much better off to just use http://khanacademy.org or http://schoolyourself.org So why are they using this expensive, seemingly untested service?
Sara Holbrook had two of her poems used on the Texas state assessment tests. She verifies what I thought as a student. The questions are ridiculous. The test makers seem to think that their interpretation of a work is the only interpretation, and that they can read the author's mind and know their intent.
"Texas paid Pearson $500 million bucks to administer the tests". Is that right? Was that for just one year? What else could we do with $500 million?
She mentions a study showing that the results of another standardized test could be predicted pretty well using just three data points about families in the community: the percentage with income over $200K; the percentage in poverty; the percentage with bachelor's degrees. So the standardized test tells you nothing that you can't guess by looking at local incomes and education levels.
What a scam.
Since there is no proven “right way” to assess and track student learning, the most effective option is to turn this responsibility over to the students. Because learning should stem from intrinsic motivation, teachers can spend time showing students how to track the feedback and their progress from long-term learning experiences. This way students will learn to reflect on their growth, set better goals, and be accountable for their own growth.

Sunil Singh asks us to stop promoting mathematics based on its current applications in business and science. Math is an art that should be enjoyed for its own sake.
This reminded me of A Mathematician's Lament by Paul Lockhart. This is a 25-page essay which was later worked into a 140-page book. (And Sunil Singh has read at least one of them. He credits Lockhart in one of the replies.)
It also reminds me of this article on the history of Gaussian elimination and the birth of matrix algebra. Newton's algebra text included instructions for solving systems of equations -- but it didn't have much practical use until later. (Silly word problems are as old as mathematics.)
We should let people learn at their own pace. We should neither rush them, nor hold them back. If they show a talent, then encouraging them to push themselves is fine.
Math isn't for everyone, and that's fine. The same is true of any other subject. We should help people learn what they are interested in learning.
Ashift is taking place in schools all over the world as learners are exploring subject matter through the act of creation rather than the consumption of conten
So interesting to see this "realization" included in the K-12 report but not in the HE report. Fostering curiousity, interest, creativity, and ownership. Short jump to an open pedagogy model but pretty unclear that's where this is coming from.
Neil Fraser says Vietnam is doing well with computer science education.
"If grade 5 students in Vietnam are performing at least on par with their grade 11 peers in the USA, what does grade 11 in Vietnam look like? I walked into a high school CS class, again without any advance notice. The class was working on the assignment below (partially translated by their teacher for my benefit afterwards). Given a data file describing a maze with diagonal walls, count the number of enclosed areas, and measure the size of the largest one."
"If given the opportunity all teachers would stop grading their students. You’ll never find a teacher who loves grading papers, projects or tests. In 20 years as a classroom teacher, I heard more complaints about grading than anything else."
"So, if they hate it so much, why don’t teachers stop grading? Because parents, administrators, and bureaucrats won’t let them."
"Real gifted education (not gifted programs) involves seeing every student as an individual, finding out what they need, what they want to learn, and what they care about, and then adapting the instructional environment and curriculum to those needs, wants, and passions."
"There’s no reason we can’t do this for everyone, letting gifted students soar without the downsides of selective gifted programs."
“Our whole reason for doing this is a social justice reason,” he said. The organization wants to make high-quality material available for free to all students.

“We see kids in their cars in the parking lot at night and on weekends,” says Buddy Berry, superintendent of Eminence Independent Schools. They’re there, he says, because they can access the Internet using the school’s wireless network—something many don’t have at home.
educators and business leaders are increasingly recognizing that CS is a “new basic” skill necessary for economic opportunity. The President referenced his Computer Science for All Initiative, which provides $4 billion in funding for states and $100 million directly for districts in his upcoming budget; and invests more than $135 million beginning this year by the National Science Foundation and the Corporation for National and Community Service to support and train CS teachers.
