Letter to Elizabeth Rees about Distant Family
No full textLetter addressed to Elizabeth Rees, but because the last pages of this letter were lost there is no way of telling who it is from. The letter states that the author’s nephew is recovering from the swelling of his limbs and is expected to be okay. The author’s cousin Thomas will be visiting soon along with the rest of his family. Then the author continues to speak of the different marriages that have been occurring locally. This is one item from the Rees Family Correspondence Collection, which includes many letters between family members in Oregon and Ohio
Letter to a Brother of the Rees Family about Politics
No full textLetter addressed to a brother of the Rees family, but neither the author of the letter nor who the letter is to be mentioned. The letter talks about local gossip in Butteville. Then the letter cuts off and switches from March to December and talks about the Presidential candidates for 1876. It was a close race between Samuel J. Tilden and Rutherford B. Hayes, with Hayes winning the election. The author of this letter strong supports the Federalist views while talking about politics during this time. This is one item from the Rees Family Correspondence Collection, which includes many letters between family members in Oregon and Ohio
Dan Rees: Think Local, Act Global [Curatorial Project]
No full textDan Rees engages with a tradition of conceptual art making, in which familiar tropes and genres – monochromes, abstracts, ready-mades – are quietly unhinged and recuperated as strategies for production. The exhibition’s central series of Artex Paintings revive a decorative ceiling pattern, popular in British working class homes during the 1970s. Creating this type of plasterwork, once a skilled manual job, has now been rendered all but redundant as the material fell out of fashion during the late 1980s. Rees’ methodology is driven through both a recognition of the steady disappearance of the working class over recent decades and the overwriting of much of its history, as much of the disappearance of artex as a decorative mean itself. Within Rees’ paintings, distinctive shell-like patterns are combed through energetically coloured fields. Incidental manifestations within the fluid oil register against the formal exercise of combing, which both obliterates and transforms the painted surface beneath.
Devoid of saturated images or commercial slogans, the impersonal forms of Rees’ Trivision Billboards punctuate the exhibition. With their industrial and austere presence, they simulate or disguise themselves as minimalist sculptures. Placed variously on the walls and floors of the gallery spaces, their repetition suggests how they might be ordered in manifold sizes and formations. However, while minimalist objects traditionally asked to be considered as materials without reference to an outside reality, Rees undermines this logic by presenting a mechanism intended to broadcast information.
Similarly, the Artex Paintings could be understood as a deliberate subversion of abstract expressionism’s themes, in which gestural spontaneity has been rendered via the methodical repetitions of a builder’s tool. In Rees’ continued examination of reproduction and repetition, the work enters the format of a series, removing it from wry conceptual exercise.
While the abstract works of the Artex Paintings and the minimalism of the billboards do not project the artist’s ideology directly, this is more clearly revealed in Rees’ video work Road Back To Relevance. Produced in collaboration with an advertising strategist and designer, the slide-show questions of how various modes of social engagement can remain relevant today by charting the course of a specific solidarity campaign, started in the 1980s between Wales and Nicaragua. While the visual tone of this work might suggest a need for such solidarity campaigns to modernise in order to reach a wider audience, the conclusion appears to be the opposite. Rather, the work points to the relevance of maintaining an inclusive and personal approach towards creating new connections between people, one that goes beyond issues of technology and dispersion.

The chemistry of fear Harvey Wiley's fight for pure food
No full text"Harvey Wiley spent most of his professional life advocating for food free of adulterants and preservatives. He was a proponent of the Pure Food and Drug Act of 1906, and he ran the Division (later Bureau) of Chemistry at the US Department of Agriculture from 1883 to 1912. He gained fame for the so-called Poison Squad experiments-in which Wiley's own employees at the USDA consumed food mixed with additives and were studied for their body chemistry. In this biography, Jonathan Rees examines Wiley's many and varied conflicts over food safety"-
Infrequent mutation of p16INK4 in sporadic melanoma
No full textLoss of heterozygosity of chromosome region 9p21 occurs commonly and early in sporadic melanoma, suggesting the involvement of a tumor suppressor gene at this locus in the pathogenesis of this neoplasm. Although germline mutations and deletions of the p16INK4 gene located at 9p21 have been reported in familial melanoma, the relative contributions of mutation and deletion in sporadic melanoma are at present unclear. In this study, we investigated 26 cases of sporadic cutaneous melanoma (14 of which demonstrated loss of heterozygosity at 9p21) for mutations of p16INK4. One tumor with allelic loss of 9p contained a CC-->TT mutation at codons 57/58, altering an arginine to a stop codon, consistent with bi-allelic inactivation of p16INK4 in this case. No mutations were identified in any of the other melanomas, or in one benign intradermal nevus with atypical features and two Spitz nevi that also showed loss of heterozygosity of 9p. The inactivation of both copies of p16INK4 in the one case of melanoma adds support to the theory that p16INK4 is important in the development of sporadic cutaneous melanoma, although allelic loss or other methods of inactivation of p16INK4 rather than point mutation appears to be numerically more important. The low frequency of mutation of p16INK4 in cases of sporadic melanoma with loss of heterozygosity of 9p is, however, also consistent with there being another tumor suppressor gene near this locus that is involved in some cases of sporadic melanoma
Measuring disease in dermatology: studies of objective and subjective methods
No full textItch lies second only to disturbance of body image as a reported symptom in dermatology.
This study started by concentrating on improving the measurement of itch. Itch has a paired
physical response, scratch. The pairing can be exploited: preliminary work by this unit had
validated the use of wrist-worn movement-measuring machines called ‘accelerometers’ to
measure itch-related movement (scratch and rub). The first part of this research developed
use of these machines. Simple accelerometers (‘Actiwatch Plus’) were used to observe the
pattern of variation of itch over clusters of nights and in different conditions. The
accelerometer scores were able to identify controls’ scores from those with itchy disease.
Considerable variation (56%) was discovered in objective score between subject and
considerable variation was noted (46%) even within subject. More complex accelerometers,
(‘DigiTrac’) which could potentially specifically identify itch-related movement on the basis
of frequency of action derived from Fast Fourier Transform (FFT), were validated against
the ‘gold standard’ measurement of itch-related movement, directly observed movement (via
infra red video recording). It was necessary to characterise the ‘frequency of action’ of itch
on video and, as an aside, the characteristics of human itch-related movement were
compared to other mammals’ itch-related movement ‘frequency of action’. The ‘frequency
of action’ and video data was used to enrich the DigiTrac readouts to improve specificity of
itch-related movement detection.
During the accelerometer studies, an unexpected finding came to light: objective score of
itch was not related to subjective score. To try to explain the lack of relationship, a 42 day
longitudinal study of atopic dermatitis patients’ subjective and objective scores was
undertaken. The results demonstrated autocorrelation for subjective scores, but not for the
objective scores but still did not fully explain the lack of relationship.
In an effort to explain the disconnect between subjective and objective scores a second
tranche of experiments and the second part of this research interrogated whether the methods
with which we measure disease as a whole in dermatology are robust. One study
investigated whether the way patients are asked about subjective symptoms in general was
resistant to the effects of focusing and framing bias. The results were reassuring as they
suggested that the commonly used and recommended symptom scoring systems were robust
in the face of bias. In order to assess whether perspective or perception of disease explained
the disconnect, a study was designed in collaboration with the Edinburgh College of Art. A
series of computer-generated images of different psoriasis severities were created and used
to assess how doctors and patients assessed disease-extent. This study showed that, whilst
each group had a naturally divergent opinion of extent of disease, by scoring disease using
the models it was possible to unify the perspective and perception of extent. Finally, an
exploratory study to reduce recall bias to a minimum, in case this had caused the disconnect
between objective and subjective, was undertaken. This employed a novel questionnaire, the

On the future: prospects for humanity/ Martin Rees, with a new preface by the author.
No full textDescription based upon print version of record.Includes bibliographical references and index.A provocative and inspiring look at the future of humanity and science from world-renowned scientist and bestselling author Martin ReesHumanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes--good and bad--are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and bestselling author Martin Rees argues that humanity's prospects depend on our taking a very different approach to planning for tomorrow.The future of humanity is bound to the future of science and hinges on how successfully we harness technological advances to address our challenges. If we are to use science to solve our problems while avoiding its dystopian risks, we must think rationally, globally, collectively, and optimistically about the long term. Advances in biotechnology, cybertechnology, robotics, and artificial intelligence--if pursued and applied wisely--could empower us to boost the developing and developed world and overcome the threats humanity faces on Earth, from climate change to nuclear war. At the same time, further advances in space science will allow humans to explore the solar system and beyond with robots and AI. But there is no "Plan B" for Earth--no viable alternative within reach if we do not care for our home planet.Rich with fascinating insights into cutting-edge science and technology, this accessible book will captivate anyone who wants to understand the critical issues that will define the future of humanity on Earth and beyond.Cover -- Contents -- Preface to the Paperback Edition -- Introduction -- 1.
