Interview with Earnest C. Watson
No full textAn interview in January 1969 with Earnest C. Watson, retired dean of the faculty emeritus and emeritus professor of physics. Dr. Watson arrived at Caltech in 1919 after graduate work with R. A. Millikan at the University of Chicago and two years of military service in World War I. He immediately supervised the design and construction of the Norman Bridge Laboratory of Physics and thereafter became chief assistant to Dr. Millikan when the latter arrived as Caltech’s first head (chairman of the Executive Council) in 1921.
Watson became dean of the faculty in 1946 and held that position through 1959, when he retired. In January 1960 he left Caltech for India, as scientific attaché to the U.S. Embassy there.
In this interview, he reminisces about his relationship with Millikan and with Arthur Amos Noyes, the development of Caltech in the institute’s early years, and Millikan’s carte-blanche from the Board of Trustees. He comments on the campus mood during the Depression era; the rise of Communist-leaning discussion groups; and the persecution of aeronautical engineer Hsue-shen Tsien in the McCarthy era. He recalls Einstein’s visits to Caltech in the 1930s and the Millikans’ careful supervision of his contacts. He comments on industrial funding for Caltech, on the collapse of the Arthur H. Fleming trust at the outset of the Depression, and on his close relationship with trustees William C. McDuffie and James R. Page. He concludes by discussing his own role in developing and running the institute

Psychosocial influences on drug driving in young Australian drivers
No full textEpidemiological evidence regarding the occurrence of drug driving amongst young drivers is concerning. This study examined the prevalence of drug driving in a sample of 331 young Australian drivers (average age 24 years), as well as a number of social and psychological influences associated with the behaviour. Results revealed that 26% reported having driven under the influence of psychoactive drugs at least once in their lifetime, and 15% indicated driving within 6 hours of taking drugs and alcohol. While no participants reported being convicted of a drug driving offence, 3% had been involved in one or more crashes whilst drug driving (10% of those who had ever drug driven). Investigations revealed that drug driving behaviour was significantly correlated with vicarious punishment avoidance (r = .41) and direct punishment avoidance (r = .35), suggesting an important link between young peoples’ perceptions about detection and punishment and their own propensity to drug drive. Sensation seeking (r = .24) and attitudes (r = .34) were also significantly correlated with drug driving. Further evidence indicated that those who perceived more social and non-social rewards than punishments associated with drug driving, were more likely to engage in the behaviour. Results suggest that perceptions about detection and punishment are an important influence upon drug driving behaviour for young drivers. The social and non-social rewards associated with drug driving also play an important role
Judy Watson: A Waanyi artist in Italy
No full textArtist Judy Watson, a member of the Waanyi people of north-west Queensland, has spent several periods in Italy, including on a residency in Tuscany in 1992, and when selected to present her work in the Australian pavilion at the Venice Biennale in 1997 and as a speaker at the aabaakwad gathering of First Nations artists at the Biennale in 2022. In the interview, Watson reflects on her connection to culture and Country and speaks of the works inspired by her stays in Italy. She also comments on changes over time in the Venice Biennale, as well as the interest in Indigenous Australian artists in Italy.No Full Tex
A simple two-module problem to exemplify building-block assembly under crossover
No full textTheoretically and empirically it is clear that a genetic algorithm with crossover will outperform a genetic algorithm without crossover in some fitness landscapes, and vice versa in other landscapes. Despite an extensive literature on the subject, and recent proofs of a principled distinction in the abilities of crossover and non-crossover algorithms for a particular theoretical landscape, building general intuitions about when and why crossover performs well when it does is a different matter. In particular, the proposal that crossover might enable the assembly of good building-blocks has been difficult to verify despite many attempts at idealized building-block landscapes. Here we show the first example of a two-module problem that shows a principled advantage for cross-over. This allows us to understand building-block assembly under crossover quite straightforwardly and build intuition about more general landscape classes favoring crossover or disfavoring it
A Boyer-Moore (or Watson-Watson) type algorithm for regular tree pattern matching
No full textIn this chapter, I outline a new algorithm for regular tree pattern matching. The existence of this algorithm was first mentioned in the statements accompanying my dissertation, [2]. In order to avoid repeating the material in my dissertation, it is assumed that the reader is familiar with Chapters 4 and 5 of the dissertation.

Transformations in the Scale of Behaviour and the Global Optimisation of Constraints in Adaptive Networks
No full textThe natural energy minimisation behaviour of a dynamical system can be interpreted as a simple optimisation process, finding a locally optimal resolution of problem constraints. In human problem solving, high-dimensional problems are often made much easier by inferring a low-dimensional model of the system in which search is more effective. But this is an approach that seems to require top-down domain knowledge; not one amenable to the spontaneous energy minimisation behaviour of a natural dynamical system. However, in this paper we investigate the ability of distributed dynamical systems to improve their constraint resolution ability over time by self-organisation. We use a ‘self-modelling’ Hopfield network with a novel type of associative connection to illustrate how slowly changing relationships between system components can result in a transformation into a new system which is a low-dimensional caricature of the original system. The energy minimisation behaviour of this new system is significantly more effective at globally resolving the original system constraints. This model uses only very simple, and fully-distributed positive feedback mechanisms that are relevant to other ‘active linking’ and adaptive networks. We discuss how this neural network model helps us to understand transformations and emergent collective behaviour in various non-neural adaptive networks such as social, genetic and ecological networks

Governor Watson C. Squire proclamation warning against anti-Chinese rioting, November 4, 1885
No full textWashington Territory Governor Watson C. Squire issued this proclamation urging residents to cease anti-Chinese agitation. He states that peaceful behavior is essential for residents of a territory which is interested in becoming a state, and warns that if peace is not kept, to remember "the fate of Wyoming and the speedy interference of United States troops."This proclamation was followed by another on November 7, 1885, by President Grover Cleveland, which restated the warning and said that military force would be engaged if the warning was not heeded.
Watson Carvosso Squire, 1838-1926, was an attorney, Civil War veteran, industrialist, and governor of Washington Territory from 1884-1887. In 1885, anti-Chinese riots began occurring in Tacoma and Seattle. This trouble peaked on February 8, 1886, when Squire declared martial law. Following his tenure as Governor, Squire served in the US Senate
Assembly of 913 microbial genomes from metagenomic sequencing of the cow rumen
No full textThis dataset represents 913 draft bacterial and archaeal genomes assembled from over 800 gigabases of rumen metagenomic sequence data derived from 43 Scottish cattle, using both metagenomic binning and Hi-C-based proximity-guided assembly. Most of these genomes represent previously unsequenced strains and species. The draft genomes contain over 1.2 million predicted protein sequences, and 69,000 proteins predicted to be involved in carbohydrate metabolism.
## Relation to earlier versions ##
This data is referenced by Watson et al. (In Submission). A previous paper, in bioRXiv, referenced the earlier dataset "Assembly of hundreds of microbial genomes from the cow rumen reveals novel microbial species encoding enzymes with roles in carbohydrate metabolism" https://datashare.is.ed.ac.uk/handle/10283/2772. This in turn was superseded by the more recent version Hi-C genomes from "Assembly of hundreds of microbial genomes from the cow rumen reveals novel microbial species encoding enzymes with roles in carbohydrate metabolism"
https://datashare.is.ed.ac.uk/handle/10283/2911. The paper underwent many rounds of review, the first-round revised paper referenced the second (Hi-C) dataset and the final, accepted version will reference the DOI of this dataset. The datasets changed in nature and in name during this process
