OCCUR

OCCUR 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 OCCUR rather than just read about it. In short: OCCUR (特定非営利活動法人アカー, lit. 'Designated Non-Profit Organization "OCCUR"') is a Japanese LGBT rights organization, founded in 1986. The organization is also involved in raising awareness of and providing medical treatment for HIV/AIDS.

Key takeaways

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

Reference excerpt

OCCUR (特定非営利活動法人アカー, lit. 'Designated Non-Profit Organization "OCCUR"') is a Japanese LGBT rights organization, founded in 1986. The organization is also involved in raising awareness of and providing medical treatment for HIV/AIDS.

History OCCUR was founded in 1986 as a split of ILGA Japan, founded by several young members dissatisfied with the group's leadership. The group became known for taking more proactive media and legal roles than prior organizations in Japan. In February 1990, members of OCCUR stayed overnight at Fuchu Youth House for a study session. After members introduced themselves as members of a gay organization, they faced harassment from both other guests and the director of the facility, and were subsequently barred from using the facility by the director. In 1991, OCCUR filed a lawsuit against the Tokyo Metropolitan Government over discriminatory treatment, and the legal battle subsequently became a major focus for the group. Following two separate trials, OCCUR won the case against the government on 16 September 1997. The judgement has since been regarded as a major legal turning point on the issue of discrimination against sexual minorities in Japan. On 2 December 1999, OCCUR was officially registered as a non-profit organization. In 2018, the group's official name was changed from "Japan Association for the Lesbian & Gay Movement" to "OCCUR", which had already been in use since the organization was formed.

Worked examples

Example 1 — a first encounter with OCCUR

Start with the simplest possible case. Write down what OCCUR 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 OCCUR 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 OCCUR 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 OCCUR

In research: OCCUR 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 OCCUR 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: OCCUR is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1986 establishments in Japan, HIV/AIDS organizations, LGBTQ political advocacy groups in Japan, so understanding it makes those chapters shorter.
In everyday life: Look for OCCUR 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 OCCUR in simple terms?

Why does OCCUR 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 OCCUR?

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.
