Cinderellas in Breeches

Selvedge is a specialist textiles magazine with an international circulation. An article which documents the biography of a pair of breeches issued as part of the uniform of the Women’s Land Army during the Second World War. It considers the history of corduroy and its decline as a UK textiles industry, garment styling, manufacture and distribution to the land girls. How, where and when they were worn and the postwar biographies of breeches as ‘authentic’ uniform for living history or as stylish vintage fashion

J Cancer Surviv

PurposeThe purpose of this study is to examine reporting of treatment summaries and follow-up instructions among cancer survivors.MethodsUsing the 2010 National Health Interview Survey, we created logistic regression models among cancer survivors not in treatment (n= 1,345) to determine characteristics associated with reporting treatment summaries and written follow-up instructions, adjusting for sociodemographic, access, and cancer-related factors. Findings are presented for all survivors and those recently diagnosed ( 644 years). We also examined unadjusted associations between written instructions and subsequent surveillance and screening.ResultsAmong those recently diagnosed, 38 % reported receiving treatment summaries and 58 % reported written instructions. Among all survivors, approximately one third reported summaries and 44 % reported written instructions. After adjustment, lower reporting of summaries was associated with cancer site, race, and number of treatment modalities among those recently diagnosed, and white vs. black or Hispanic race/ethnicity, breast vs. colorectal cancer, >10 vs. 645 years since diagnosis, no clinical trials participation, and better than fair health among all survivors. For instructions, lower reporting was associated with no trials participation and lower income among those recently diagnosed, and increasing age, white vs. black race, lower income, >10 vs. 645 years since diagnosis, 1 vs. 652 treatment modalities, no trials participation, and at least good vs. fair/poor health among all survivors. Written instructions were associated with reporting provider recommendations for breast and cervical cancer surveillance, and recent screening mammograms.ConclusionMany recently diagnosed cancer survivors did not report receiving treatment summaries and written follow-up instructions. Opportunities exist to examine associations between use of these documents and recommended care and outcomes, and to facilitate their adoption.Implications for cancer survivorsCancer survivors who have completed therapy should ask their providers for treatment summaries and written follow-up instructions, and discuss with them how their cancer and therapy impact their future health care.CC999999/Intramural CDC HHS/United States2018-03-14T00:00:00Z23179495PMC5850952vault:2756

The behavioural consequences of reduced sea water pH in decapod crustaceans

The studies presented in this thesis were designed to investigate the effects of reduced sea water pH on the behaviour of intertidal decapod crustaceans, both within the context of the variations occurring naturally in the pH of rock pool habitats, and in relation to predicted changes to ocean pH resulting from ocean acidification and potential carbon dioxide (CO2) leaks from carbon capture storage (CCS) sites. Recent studies on marine fish have shown behavioural disruptions as a result of increased CO2 concentrations in sea water and reduced pH, but the effects on crustaceans are as yet unknown. The first two studies investigated the effects of reduced pH upon the olfactory behaviour of the prawn Palaemon elegans and the hermit crab Pagurus bernhardus, focussing on their responses to food odours. Short-term (five day) exposures to highly reduced pH (pHNBS = 6.60, 6.80) revealed disruptions to the chemo-sensory behaviour of both species with a reduction in their ‘sniffing’ response, and the inability of P. bernhardus to locate the chemical cue. This was also accompanied by elevated haemolymph chloride ions. in In a further study P. bernhardus was subjected to a longer exposure (60 days) and to a range of pH levels (pHNBS = 8.00, 7.90, 7.70, 7.35 and 6.80) in order to detect a threshold for the behavioural disruptions observed, and to determine if there would be any sign of acclimation over a longer period. A clear gradient in the disruptions to the chemo-sensory responses and survival rates of the hermit crabs, and disruption to a physiological marker (elevated haemolymph calcium ions), was found. Possible thresholds for disruption were also identified at levels that match predictions for ocean acidification and leaks from proposed CO2 CCS sites. Some of the crabs in the lower pH treatments exhibited a recovery in their responses by day 60, possibly indicating an acclimation effect. The presence of disruption to haemolymph ion concentrations in both the short and longer term hermit crab studies suggest a mechanism for behavioural disruption. In a final study the effects of reduced sea water pH on a more complex behaviour, involving decision making, was investigated. Reduced sea water pH was shown to disrupt the shell assessment and selection behaviour of P. bernhardus affecting its decision making processes, although not all crabs were affected in the same way. The work presented here therefore demonstrates that reduced sea water pH could have disruptive effects upon both information gathering, via chemo-sensory processes, and decision making in intertidal crustaceans. The mechanism responsible is unlikely to be due to changes in the odour molecule, or physical damage to receptor organs. Rather the observed disruptions could be due (a) to ionic changes, causing metabolic depression or interference with neurotransmitter function, or (b) to disruption to chemoreception per se. Such disturbances to key behavioural processes have implications for inter and intraspecific species interactions and population dynamics in the marine environment. Changes in pH are already experienced by intertidal animals for short periods when rock pools are emersed, but future anthropogencially-induced reductions in sea water pH are likely to cause more sustained and widespread disruptions with, as yet, unpredictable consequences. The differential responses observed between individuals in these studies may warrant further investigation as such differences may provide the basis for selection and adaptation to projected changes in ocean pH

Ravishing: The Rose in Fashion

An exploration of how the rose—the most ravishingly beautiful and symbolic of flowers—has inspired fashion over hundreds of years. The Rose in Fashion: Ravishing is a fascinating exploration of how the rose has inspired the way we look, dress, feel, and fantasize. It foregrounds innovative, refined, and challenging fashion design from elite 18th-century woven silks to the latest gender-neutral catwalk trends and Alexander McQueen rose dresses. Drawing upon fashion clothing, everyday dress, millinery, fine jewelry, perfume, and artificial and fresh roses, multiple expert contributors make reference to love, beauty, sex, sin, gendered identities, rites of passage, transgression, degradation, and death. This sumptuously illustrated book also includes a contribution and stunning images of roses by visionary photographer Nick Knight. Wild yet cultivated, savage yet delicate, this flower has remained an enduring symbol perhaps due to its versatility and the dichotomies it represents.

Exploring teachers' perspectives about executive functions in the primary school context in New Zealand : a thesis presented in partial fulfillment of the requirements for the degree of Master of Educational Psychology at Massey University, Albany, New Zealand

Cognitive psychology research has suggested that executive functions (EFs), a set of cognitive skills that facilitate goal-directed behaviour, play an important role in learning and academic success. EFs, comprised of the three core cognitive components of inhibitory skills, working memory, and cognitive flexibility, are also associated with social-emotional learning and competency. Research has also shown that targeted teaching and practice can improve EFs, with far reaching benefits. However, there is currently little evidence about whether teachers are aware of these skills, or of their importance. This study, therefore, explored New Zealand primary teachers’ perspectives about EFs as a necessary first step to understanding teachers’ knowledge, values and practice in New Zealand. The study used a mixed methods design to obtain quantitative and qualitative data through an online survey. Results indicated that teachers were generally aware that there is a set of non subject-specific skills that are important to learning, but their knowledge and understanding of EFs themselves, prior to completion of the survey, was limited. Teachers rated all EFs as very important to learning and the majority of teachers were already attempting to support development of EFs within their classroom practice. Knowledge of and use of specific activities or teaching strategies to target development of specific EFs was limited, however many teachers were providing learning environments conducive to using and practicing EFs. This research highlights the need for professional development and support for teachers to develop their understanding of EFs. It also demonstrated a need to provide teachers with a range of teaching strategies and activities to integrate within their current learning environments in order to better support development of EFs within their students

Quantitative Tverberg theorems over lattices and other discrete sets

This paper presents a new variation of Tverberg's theorem. Given a discrete set $S$ of $R^d$, we study the number of points of $S$ needed to guarantee the existence of an $m$-partition of the points such that the intersection of the $m$ convex hulls of the parts contains at least $k$ points of $S$. The proofs of the main results require new quantitative versions of Helly's and Carath\'eodory's theorems.Comment: 16 pages. arXiv admin note: substantial text overlap with arXiv:1503.0611

Helly numbers of Algebraic Subsets of Rd\mathbb R^d

We study $S$-convex sets, which are the geometric objects obtained as the intersection of the usual convex sets in $\mathbb R^d$ with a proper subset $S\subset \mathbb R^d$. We contribute new results about their $S$-Helly numbers. We extend prior work for $S=\mathbb R^d$, $\mathbb Z^d$, and $\mathbb Z^{d-k}\times\mathbb R^k$; we give sharp bounds on the $S$-Helly numbers in several new cases. We considered the situation for low-dimensional $S$ and for sets $S$ that have some algebraic structure, in particular when $S$ is an arbitrary subgroup of $\mathbb R^d$ or when $S$ is the difference between a lattice and some of its sublattices. By abstracting the ingredients of Lov\'asz method we obtain colorful versions of many monochromatic Helly-type results, including several colorful versions of our own results.Comment: 13 pages, 3 figures.
