Jock Alves

Jock Alves 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 Jock Alves rather than just read about it. In short: William "Jock" Alves (c. 1909 – 10 February 1979) was a Scottish-born Rhodesian physician and politician who served as mayor of Salisbury (now Harare) from 1972 to 1974. He later served as a member of the Senate of Rhodesia until his death.

Jock Alves belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Jock Alves to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

William "Jock" Alves (c. 1909 – 10 February 1979) was a Scottish-born Rhodesian physician and politician who served as mayor of Salisbury (now Harare) from 1972 to 1974. He later served as a member of the Senate of Rhodesia until his death. An epidemiologist by profession, he directed a bilharzia research laboratory in Salisbury and later worked with the World Health Organization on parasitic disease projects.

Medical career Alves was of Scottish origin. Alves earned his Bachelor of Arts from a South African university. He pursued his doctorate at the London School of Hygiene & Tropical Medicine, but had to return to Southern Rhodesia in 1947 before completing his degree. He later returned and was awarded a PhD in 1953. Alves was a physician and was the director of the Bilharzia and Malaria Research Laboratory in Salisbury from 1944 into the 1950s. He also belonged to the department of parasitology at the London School of Hygiene & Tropical Medicine. He was considered an international authority on bilharzia, and during his tenure at the laboratory developed a treatment for the disease that was successfully tested on 25 patients. He served on the World Health Organization (WHO) expert committee on parasitic diseases. In 1958, he led a WHO project in the Philippines. In 1961, he was senior advisor on a WHO malaria eradication project in the Solomon Islands.

Political career Alves was elected to the Salisbury City Council and served as deputy mayor from 1971 to 1972 under Mayor Roger Bates. On 2 August 1972, he was sworn in as mayor Salisbury at a special meeting of the city council. He served as mayor until 7 August 1974, when he was succeeded by Tony Tanser. Alves continued to serve on the city council, and later became a member of the Rhodesian senate. In 1978, as chairman of the city council's African affairs committee, Alves introduced a scheme to set up a two-tier system in which blacks and whites would each have municipal representation on their own city councils. The proposal passed without debate in January 1978. In June 1978, Alves made a speech before the senate in which he urged the Rhodesian government to include the African nationalist leader Joshua Nkomo, and possibly Robert Mugabe, in any potential settlement negotiations. He was a member of the ruling Rhodesian Front party, and was for a time a party spokesman. Alves died at Andrew Fleming Hospital in Salisbury on 10 February 1979, aged 70.

Worked examples

Example 1 — a first encounter with Jock Alves

Start with the simplest possible case. Write down what Jock Alves 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 Jock Alves 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 Jock Alves 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 Jock Alves

In research: Jock Alves 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 Jock Alves 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: Jock Alves is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900s births, 1979 deaths, 20th-century Scottish medical doctors, so understanding it makes those chapters shorter.
In everyday life: Look for Jock Alves 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.
