Single-celling

Single-celling is a biology 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 Single-celling rather than just read about it. In short: Single-celling is the practice of assigning only one inmate to each cell in a prison. John Howard has been credited as establishing the practice of single-celling in the United Kingdom and, by extension, in the United States.

Key takeaways

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

Reference excerpt

Single-celling is the practice of assigning only one inmate to each cell in a prison. John Howard has been credited as establishing the practice of single-celling in the United Kingdom and, by extension, in the United States. In 1957, only 15 prisons in the United States practiced single-celling exclusively while 41 prisons employed it with a portion of their cells and 44 housed multiple prisoners in all of their cells. Critics of single-celling suggest that the practice imposes psychologically harmful isolation on inmates, while advocates argue that single-celling alleviates many of the inmates' discomforts. The practice in many prisons of allowing general population prisoners to freely intermingle during normal hours diminishes the critics argument, while single celling gives prisoners a (relatively) safe place to retreat. The majority of cells allow the cell doors to be closed by an inmate and automatically lock. This provides additional security to potentially at-risk individuals. Single celling also improves investigations of contraband possession since only a single inmate is assigned to a cell.

Worked examples

Example 1 — a first encounter with Single-celling

Start with the simplest possible case. Write down what Single-celling claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Single-celling 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 Single-celling 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 Single-celling

In research
Single-celling appears in biology 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 Single-celling 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
Single-celling is common in secondary-school and first-year university syllabi. It links to neighbouring topics Forensic psychology, Penal imprisonment, Penology, so understanding it makes those chapters shorter.
In everyday life
Look for Single-celling 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 Single-celling in simple terms?

Single-celling is the practice of assigning only one inmate to each cell in a prison. John Howard has been credited as establishing the practice of single-celling in the United Kingdom and, by extension, in the United States.

Why does Single-celling matter?

Because it connects several biology 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 Single-celling?

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.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Single-celling.
