Recovery through contradiction?
No full textWith this new drug strategy, the circle has turned. It was a Conservative government
that introduced the first drug strategy, Tackling Drugs Together, in 1995. This aimed
to reduce drug related crime, protect young people and reduce health harms by
discouraging drug use. It was criticised at the time for having unrealistic, intangible
aims and for not providing the necessary funding. New Labour’s strategies introduced
increasingly specific targets and massively expanded the funding of treatment. This
new Coalition strategy has no targets and provides no new funding
Gwendolyne Stevens
No full text"Gwendolyne Daphne was born on 7 June 1908 at Quorn, South Australia, daughter of Hugo Albert Valentine Healey, painter and later publican, and his wife Jessie Gwendolyne, n?e Napier, both South Australian born.
Gwendolyne attended several rural schools, including Innamincka Public, before proceeding to St Peter's Collegiate Girls' School, Adelaide. Miss Healey trained at Burra public and (Royal) Adelaide hospitals, and was registered as a nurse on 11 July 1929. She then moved to Parkside Mental Hospital where she gained a certificate in psychiatric nursing in 1931 and became sister-in-charge. In 1934 she bought a large house at Payneham that had been built by James Marshall, converted it into a private psychiatric hospital and named it St Margarets. As its owner and matron for eighteen years, she cared for patients suffering the early stages of nervous disorders, and provided them with a secure and restful setting, with aviaries amid beautiful gardens. That she took on such a task during the depression, and succeeded in it, testified to her business acumen, organizing ability and compassion for those in need.
At the chapel of the Collegiate School of St Peter, Adelaide, on 12 April 1940, she married George Dempster Stevens, a clerk employed by Dalgety & Co. Ltd. They were to have two daughters.
Pursuing her interest in community health, Mrs Stevens was founding president (1944-50) and a committee-member (until 1961) of the Payneham branch of the Mothers' and Babies' Health Association.
After she sold her hospital in 1952, she set up Sterling Downs, a Poll Dorset stud on 2200 acres (890 ha) at Currency Creek, in 1957. She employed a manager to supervise the stud and visited it each week. In the 1960s she sold part of the land and moved the stud to Sterling Park, McLaren Vale. The stud was later sold and its sheep replaced with cattle.
Having noticed particular outcrops of rock at Sterling Park, Stevens arranged for drilling to be conducted, as a result of which she opened a quarry and sold building sands to the local council.
In 1968 she became interested in the mining potential of the Northern Territory. She studied maps, obtained advice from geologists and concentrated on an area near Oenpelli, Arnhem Land. She received permission to prospect on 1282 sq. miles (3320 km?) of Aboriginal reserve and negotiated an exploration programme with Queensland Mines Ltd.
In 1970 that company discovered what was then described as the richest body of uranium ore in the world, at a site known to local Aborigines as Nabarlek.
Newspapers referred to Stevens as 'probably the first woman in the world with a right to mine uranium'. She visited the area twice during the early stages of exploration and was staggered by the size of the find.
In August 1971, however, Queensland Mines downgraded the ore reserves to about one-sixth of those announced a year earlier. Intending to use some of the proceeds of her investment to benefit the health of the Aborigines, she transferred the exploration licences to Queensland Mines in May 1973 and negotiated a royalty agreement. Mining at Nabarlek began in 1979.
Mrs Stevens both created and took advantage of opportunities in the areas of mental health, sheep-breeding and mining. Suffering from hypertension, she died of a cerebral haemorrhage on 3 March 1974 in her Kensington Park home and was cremated. She was survived by her husband and their daughters. Her estate was sworn for probate at $416,266." [author Tony Bott].NurseSheep BreederMining EntrepreneurHospital Proprieto
CWI cryptanalyst discovers new cryptographic attack variant in Flame spy malware
No full textCryptanalyst Marc Stevens from the Centrum Wiskunde & Informatica (CWI) in Amsterdam, known for breaking the https security in 2008 using a cryptanalytic attack on MD5, analyzed the recent Flame virus this week. He discovered that for this spy malware an as yet unknown cryptographic attack variant of his own MD5 attack is used. Stevens analyzed this with new forensic software that he developed. Initially, the researcher assumed that Flame used his own attack, which was made public in June 2009, but this was not the case. “Flame uses a completely new variant of a ‘chosen prefix collision attack’ to impersonate a legitimate security update from Microsoft. The design of this new variant required world-class cryptanalysis,” says Marc Stevens. “It is very important to invest in cryptographic research, to continue to be ahead of these developments in practice.

Replication Data for: How can social branding mitigate racism among fans in sports? A Q-sort analysis on the value of social branding campaigns as vehicles for reducing racism among soccer fans.
No full textThese are the tables of the analyses of the study of Stevens and Cremers (2021) in the Journal of Public Administration and Governance with the title: How can social branding reduce racism among fans in sport? An explorative study on the value of social branding campaigns as vehicles for banning racism from soccer stadiums. Feel free to contact the author for information about the analysis
A survey of chosen-prefix collision attacks
No full textIn Chapter 7, A Survey of Chosen-Prefix Collision Attacks, Marc Stevens surveys the technical advances, impact and usage of collision attacks for the most widely used cryptographic hash functions. Cryptographic hash function are the Swiss army knives within cryptography and are used in many applications including digital signature schemes, message authentication codes, password hashing, cryptocurrencies and content-addressable storage. Stevens was one of the driving forces in turning initial weaknesses in the compression function into practical attacks against various widely deployed protocols relying on hash function collision resistance for their security. In Chapter 7 he explains how each scenario involves the development of slightly different ideas to exploit weaknesses in especially MD5
G6K-GPU-Tensor
No full textG6K is an open-source C++ and Python (2) library that implements several Sieve algorithms to be used in more advanced lattice reduction tasks. It follows the stateful machine framework from:
Martin R. Albrecht and Léo Ducas and Gottfried Herold and Elena Kirshanova and Eamonn W. Postlethwaite and Marc Stevens, The General Sieve Kernel and New Records in Lattice Reduction.
The main source is available in fplll/g6k
This fork expands the G6K implementation with GPU, and in particular Tensor Core, accelerated sieves, and is accompanied by the work:
