Snowpack ground truth: Radar test site, Steamboat Springs, Colorado, 8-16 April 1976

Ground-truth data taken at Steamboat Springs, Colorado is presented. Data taken during the period April 8, 1976 - April 16, 1976 included the following: (1) snow depths and densities at selected locations (using a Mount Rose snow tube); (2) snow pits for temperature, density, and liquid water determinations using the freezing calorimetry technique and vertical layer classification; (3) snow walls were also constructed of various cross sections and documented with respect to sizes and snow characteristics; (4) soil moisture at selected locations; and (5) appropriate air temperature and weather data

Truth be Told: Utilizing Music to (Re)define the Narrative of Black Women Educators’ Lived Experiences

The experiences of Black women in the academy are unique and extremely nuanced. In this track, we utilize Black feminist thought (BFT) to explore how music can be used to [re]define Black women educators’ lived experiences. We meaningfully and symbolically explore song lyrics from notable Black women artists to uncover how racism, sexism, and other interlocking systems of oppression and privilege manifest in and create barriers for Black women to thrive and sustain in educational environments. By utilizing pop cultural analysis methodologies, we engage in storytelling as cultural productions, to not only highlight authentic counternarratives but also challenge dominant narratives that may perpetuate harmful stereotypes or overlook the unique struggles faced by Black women in academia. Produced with the principle of recognizing that Black women educators have the agency, autonomy, and power to self-define and self-affirm our lived experiences

The relationship of body weight to response to endocrine therapy, steroid hormone receptors and survival of patients with advanced cancer of the breast.

High body weight is associated with increased production of oestrogens which may influence the clinical behaviour of breast cancer. We have examined the influence of body weight on the response to endocrine therapy, steroid hormone receptor content and survival in 227 women who either presented with or developed advanced cancer of the breast. One hundred and thirty-three (59%) patients presented with operable disease and 94 (41%) with locally advanced tumours. Two hundred (88%) were treated by tamoxifen and 27 (12%) by ovarian ablation. High body weight was correlated with advanced tumour stage (P = 0.002) and progesterone receptor (PR) positivity (P = 0.01), but not with the presence of oestrogen receptor (ER P = 0.21). The association between high body weight and PR positivity was particularly noticeable among ER positive tumours. There was no significant relationship between the nature of the response to therapy and weight (P = 0.57). There was no significant difference in survival from the start of endocrine therapy (P = 0.95), nor the time to progression of disease (P = 0.29) between patients above and below the median weight of 64 kg. Among the patients with operable disease, there was no difference in overall survival (P = 0.42), relapse free survival (P = 0.69), and survival from the start of endocrine therapy (P = 0.85) according to body weight

What you need to know about: delirium in older adults in hospital

Delirium is a clinical syndrome characterised by a disturbance of perception, consciousness and/or cognitive function, with an acute onset, fluctuating course and a severe deterioration arising over hours or days. Delirium is usually triggered by a combination of influences including acute illness, surgery, drugs and environmental factors. It is commonly seen in older people presenting to hospital, but can also develop during hospitalisation. There are three types of delirium: hypoactive, hyperactive and mixed. All patients over 65 years old presenting to hospital should be screened for delirium using the ‘4AT’ tool. An alternate method for diagnosing hospital-acquired delirium is described. This article outlines a 10-stage method for diagnosing, managing and preventing delirium, with emphasis on which areas of the history and examination should be prioritised, what the salient investigations are and both non-pharmacological and pharmacological approaches to preventing and treating delirium. Finally, this article explores which patients require specialist referrals or investigations and how to best follow up patients with delirium

The politics of innovation: why innovations need a godfather

Innovation is closely linked to the development of technology. Hence it is often assumed that when an innovation fails it is the technology that is at fault. While this may be true in many instances, there are occasions when it is not the technology that is at fault, rather, it is managerial and organisational aspects that cause problems and lead to failure. Studies have shown that individuals who take on specific roles can play an important part in avoiding these problems. These roles include the technological gatekeeper, the product champion and the sponsor/coach. In addition to these roles, this paper argues that there is another, namely that of godfather. With this role a highly respected, senior figure within an organisation provides support that is critical in ensuring the project overcomes the hurdles that lie in the path of any major new development. The nature of the godfather role is explored through three case studies. These provide examples of the role and show how it can facilitate the innovation process

Optically excited states in positronium

Optical excitation are reported of the 1 3S-2 3P transition in positronium, and a second excitation from n=2 to higher n states. The experiment used light from two pulsed dye lasers. Changes in the positronium annihilation rate during and after the laser pulse were used to deduce the excited state populations. The n=2 level was found to be saturable and excitable to a substantial fraction of n=2 positronium to higher levels. Preliminary spectroscopic measurements were performed on n=14 and n=15 positronium

Some of the Effects of Domestic Sewage Discharged Into Hickman and Jessamine Creeks in Jessamine County, Kentucky

A 6-week study was made in the summer of 1971 as an initial effort to determine the extent of pollution that the three sewage disposal plants in Jessamine County, Kentucky, are contributing to its streams. With the rapid population increase in Lexington and nearby municipalities, this study should furnish a basis of comparison for future investigations. Eighteen collecting stations were established in riffle areas of Hickman and Jessamine Creeks, and coliform bacteria, macro-invertebrate populations, fish populations and chemical water quality of each riffle area were studied. Hickman Creek\u27s flow was augmented by approximately 3,100,000 gallons/day (11,735 -m3/day) from one of the City of Lexington\u27s sewage disposal plants, and Jessamine Creek\u27s flow by 500,000 gallons/day (1,893 m3/day) from the cities of Nicholasville and Wilmore. The Lexington and Wilmore facilities were greatly overloaded. Chemical analyses were directed toward finding out the fluctuations of phosphates, sulfates, and nitrates. Water disappearing through limestone faults posed investigational problems. Hickman Creek showed evidences of pollution for a greater distance downstream than did Jessamine. Diversity of clean water indicator organisms was higher in lower Jessamine than in lower Hickman; this was particularly true for darters (Etheostoma) and stoneflies (Plecoptera). Jessamine Creek was also supporting limited game fishing
