PRxPR

PRxPR is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand PRxPR rather than just read about it. In short: PRxPR is a non-governmental, private disaster relief fund which was created to provide short-term recovery efforts as well as rebuilding assistance to Puerto Rico in the wake of the devastation caused by hurricanes Irma and Maria. They have continued to work in providing sustainable infrastructure changes to the island, as well as grants and assistance to individuals in the hardest hit areas.

Key takeaways

PRxPR belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PRxPR to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PRxPR from memory before moving on to harder problems.

Reference excerpt

PRxPR is a non-governmental, private disaster relief fund which was created to provide short-term recovery efforts as well as rebuilding assistance to Puerto Rico in the wake of the devastation caused by hurricanes Irma and Maria. They have continued to work in providing sustainable infrastructure changes to the island, as well as grants and assistance to individuals in the hardest hit areas.

Formation PRxPR was created immediately after category five hurricane Maria passed directly over Puerto Rico, causing widespread devastation across the island. Puerto Rico was left with no electricity nor available water island-wide. PRxPR was created with the goal of unifying Puerto Ricans both on and off the island in the immediate efforts of helping those in greatest need, as well as a long-term goal of assisting in rebuilding a better Puerto Rico. The founders of PRxPR are:

Carmen Báez (Former President, Latin America – Omnicom Group) María Celeste Arrarás (Emmy Award Journalist/Author – Telemundo NBCU) Francisco J. Cerezo, Esq. (Partner /US Head of Latin America – DLA Piper, LLP) Marilú Medina, Esq. (Senior Counsel – Fortune 100 Company, former partner O’Neill & Borges, LLC) Jorge Silva Puras, Esq. (Former Chief of Staff to the Governor of Puerto Rico) By October 2017 PRxPR had already raised over $530,000. The money was immediately used to provide small grants to individuals and organizations on the island to procure urgent needs of what items could be found. Initially, just obtaining necessary items was difficult. "You get a private cargo plane landing in the Aguadilla airport, and when that plane lands, is that there's not enough personnel to help unload the plane," said PRxPR co-founder Carmen Baez,”There’s not enough personnel to guard the merchandise, to load the trucks, to drive the trucks to where they're needed.” The organization has continued for the last several years now to focus on the infrastructure of the island, helping to install solar energy, water purification systems, distribute water, food and medical aid, repair structures, and provide grants to individuals, especially farmers to help them individually recover and aid in the overall recovery. “People have lost their livestock - the chicken that laid the eggs, the pork that provided the meat, their orchards and gardens that provided their vegetables.” As Federal Aid is slow to come, organizations like PRxPR are continue to provide help and hope to the people of Puerto Rico. “The most disadvantaged victims of Hurricane Maria are now the ones that are further suffering under the burden of politics,” Carmen Baez is quoted to say. “If the federal aid was limited and slow before, now it will be worse.” A year after the storm Francisco Cerezo, an attorney and one of the founders of PRxPR, said "There is still a lot of need, But if there is one ‘semi-silver lining,’ it's that people have united to help.The diaspora always had many different kinds of divisions,” he continued. “There are all kinds of ways Puerto Ricans self-identified. But after María, the walls of self-identification came down. We rallied for each other and will continue to do so.” 100% of the donations collected by PRxPR are directed to helping, as none of the principles or volunteers are paid, and in fact themselves cover all overhead and operating expenses. Donations come both from individuals, as well as the support of several partner businesses and organizations. Puerto Rican journalist Maria Celeste commented “I continue with PRxPR (Puerto Rico for Puerto Rico), an organization with diaspora groups, that we are working on many projects, such as the construction of an orphanage for girls in Arecibo, but we are waiting for an important donation. We continue to insist on doing works that make a difference because the important thing is not to give up, “.

Worked examples

Example 1 — a first encounter with PRxPR

Start with the simplest possible case. Write down what PRxPR claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to PRxPR before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about PRxPR ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of PRxPR

In research: PRxPR appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses PRxPR in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: PRxPR is common in secondary-school and first-year university syllabi. It links to neighbouring topics Disaster recovery, so understanding it makes those chapters shorter.
In everyday life: Look for PRxPR outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is PRxPR in simple terms?

Why does PRxPR matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study PRxPR?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
