BUSINESS CYCLE AND LONG-TERM DEBT: EFFECTS ON HOTEL OPERATING LEASE

Over the last 25 years, many hotel operators have chosen to lease their property instead of owning as a financing strategy. This paper examines the combined and separate contributions of business cycles and a firm’s level of long-term debt on hotel owner/operator use of operating leases. The results indicate that operating leases were used more often during contracting business cycles and less often during cycles of expansion. According to the results, operating leases and long-term debt are not complementary, although they are increasingly treated as complements when the economy suffers a downturn

Donating breastmilk: Regulated and unregulated practices: A review of the ethical issues

Breastmilk is the optimal source of nutrition for babies although there are a range of situations in which breastfeeding is difficult, including prematurity. Human milk is donated in the UK in both regulated and unregulated ways. A network of human milk banks receive and distribute donor milk, primarily to premature and sick infants, supported by NICE guidance (NICE, 2010) and the UK Association for Milk Banking (UKAMB). Variations in the geographical spread and funding of the banks mean that women who want to donate or receive breastmilk are not always able to do so. Discourse around the ethics of the provision and use of human milk in this way often emphasises issues of risk and safety.There are also ways in which breastmilk is donated informally, often using the terminology of ‘sharing’, usually to full-term infants. Some women feed each other’s babies via friendship groups whilst others contact each other using online (often international) networks specifically set up for the purpose of peer-to-peer human milk sharing. Health bodies in a number of countries (although not in the UK) have issued warnings against obtaining breastmilk in this way, focussing again on ‘danger’ and ‘risk’ and drawing on limited research evidence (Keim et al, 2013; Stuebe et al., 2014, cited in Palmquist and Doehler, 2014). In the UK the issues were raised in a recent BMJ editorial (Steele et al, 2015). Other researchers have compared the risk of sharing breastmilk with the (known) risks of formula feeding (Gribble and Hausman, 2012).These topics have been the subject of a range of academic papers as well as online discussions, raising questions about the ethical issues and obligations in both regulated and unregulated practices of milk donation. These include the nature of donation and whether donors and recipients are viewed differently according to the mode of donation (milk bank vs. milk sharing; donating vs. selling) and the situation of the recipient. Is the ethics of ‘giving’ a body product different when the product is human milk rather than blood or organs? Is this an area which should remain unregulated, as a private practice, or should it be more widely or formally considered? In addition there are a range of Issues relating to the perception of human milk – as both ‘white/liquid gold’ and ‘matter out of place’ (Douglas, 1966) – which draw on ideas of cultural unease about women’s bodily fluids. Milk for use in milk banks is depersonalised but there is unease about sharing intimate bodily fluids with known/unknown others. The focus here is on informal milk sharing – why and how it happens (the lived experience of donors and recipients) and how both donation and risk are framed and accounted for. What is known is mostly from the US and Australia; women who use websites for milk sharing talk about ‘informed choice’. Where they examine all the available evidence, share information about milk collection and storage and gather knowledge about the donor (e.g. is the donor breastfeeding her own baby?). Health professionals and non-professionals working with pregnant and lactating women may be asked for advice and need to consider these issues. My conclusion is that breastmilk donation differs from other forms of donation in important ways; donating and sharing breastmilk has increased in prevalence and possibilities but the scale and scope of informal milk sharing in the UK is unknown. Many opportunities to donate and receive breastmilk have arisen in grassroots woman-to-woman ways (in a similar way to other forms of parenting and breastfeeding support). Ideas of risk frame the ‘official’ reaction to sharing breastmilk via the internet (but not in the UK) and little is known about how individual women understand and make sense of these risks

Structure and play: rethinking regulation in the higher education sector

This paper explores possible tactics for academics working within a context of increasing regulation and constraint. One suggested tactic is to move outside of a creativity-conformity binary. Rather than understanding creativity and conformity as separable, where one is seen as excluding the other, the authors consider the potential of examining the relationships between them. The theme of 'structure and play' illustrates the argument. In the first part of the paper, using various examples from art and design - fields generally associated with creativity - the authors explore the interrelatedness of creativity and conformity. For example, how might design styles, which are generally understood as creative outcomes, constrain creativity and lead to conformity within the design field? Is fashion producing creativity or conformity? Conversely, the ways in which conformity provides the conditions for creativity are also examined. For example, the conformity imposed by the state on artists in the former communist bloc contributed to a thriving underground arts movement which challenged conformity and state regulation. Continuing the theme of 'structure and play', the authors recount a story from an Australian university which foregrounds the ongoing renegotiation of power relations in the academy. This account illustrates how programmatic government in a university, with its aim of regulating conduct, can contribute to unanticipated outcomes. The authors propose that a Foucauldian view of distributed power is useful for academics operating in a context of increasing regulation, as it brings into view sites where power might begin to be renegotiated

Extended morphometric analysis of neuronal cells with Minkowski valuations

Minkowski valuations provide a systematic framework for quantifying different aspects of morphology. In this paper we apply vector- and tensor-valued Minkowski valuations to neuronal cells from the cat's retina in order to describe their morphological structure in a comprehensive way. We introduce the framework of Minkowski valuations, discuss their implementation for neuronal cells and show how they can discriminate between cells of different types.Comment: 14 pages, 18 postscript figure

The primordial Helium-4 abundance determination: systematic effects

By extrapolating to O/H = N/H = 0 the empirical correlations Y-O/H and Y-N/H defined by a relatively large sample of ~ 45 Blue Compact Dwarfs (BCDs), we have obtained a primordial 4Helium mass fraction Yp= 0.2443+/-0.0015 with dY/dZ = 2.4+/-1.0. This result is in excellent agreement with the average Yp= 0.2452+/-0.0015 determined in the two most metal-deficient BCDs known, I Zw 18 (Zsun/50) and SBS 0335-052 (Zsun/41), where the correction for He production is smallest. The quoted error (1sigma) of < 1% is statistical and does not include systematic effects. We examine various systematic effects including collisional excitation of Hydrogen lines, ionization structure and temperature fluctuation effects, and underlying stellar HeI absorption, and conclude that combining all systematic effects, our Yp may be underestimated by ~ 2-4%. Taken at face value, our Yp implies a baryon-to-photon number ratio eta = 4.7x10^-10 and a baryon mass fraction Omega_b h^2_{100} = 0.017+/-0.005 (2sigma), consistent with the values obtained from deuterium and Cosmic Microwave Background measurements. Correcting Yp upward by 2-4% would make the agreement even better.Comment: 12 pages, 5 PS figures, to appear in "Matter in the Universe", ed P. Jetzer, K.

Pregnant women’s awareness, knowledge and beliefs about pelvic floor muscles: a cross-sectional survey

Introduction and hypothesis: Pregnant women benefit from completing pelvic floor muscle exercises (PFMEs). The aims of the study were to evaluate pregnant women’s levels of awareness, knowledge, and beliefs about the pelvic floor muscles (PFMs) and PFMEs. Methods: A cross-sectional survey was conducted. Respondents were pregnant women over the age of 18 years who attended antenatal clinics in Western Australia (WA). Questionnaire items measured awareness and knowledge about PFMs, confidence and beliefs about engaging in PFMEs, and attendance at antenatal education (ANE) classes. Chi-squared tests examined potential associations between questionnaire items and respondent characteristics. Results: Mean gestation of respondents (n = 633 out of 850; 74% response rate) was 28.7 (+7.8) weeks and 50% were giving birth for the first time. Although 76% of respondents knew that PFMs can prevent urinary incontinence, only 27% knew that they prevented faecal incontinence and 41% thought it was normal to leak urine when pregnant. Only n = 72 (11%) were practicing PFMEs. Respondents who had attended ANE (28%) were significantly more knowledgeable about pelvic floor function (p &lt; .001) and significantly less likely to believe that leaking urine during pregnancy was normal (p = 0.02), compared with those who had not attended ANE. Respondents who did not speak English at home (18%) were significantly less knowledgeable about PFMs and PFMEs, and significantly less likely to have attended, or planned to attend, ANE classes. Conclusion: Pregnant women require more health education regarding PFMs. Education should be provided using diverse modes, especially for women from migrant backgrounds and women who do not plan to attend formal ANE classes

IRAS F02044+0957: radio source in interacting system of galaxies

The steep spectrum of IRAS F02044+0957 was obtained with the RATAN-600 radio telescope at four frequencies. Optical spectroscopy of the system components, was carried out with the 2.1m telescope of the Guillermo Haro Observatory. Observational data allow us to conclude that this object is a pair of interacting galaxies, a LINER and a HII galaxy, at $z=0.093$.Comment: 2 pages, 2 EPS-figures, uses newpasp.sty.

The Acid Test of Fluoride: How pH Modulates Toxicity

Background: It is not known why the ameloblasts responsible for dental enamel formation are uniquely sensitive to fluoride ($F^−$). Herein, we present a novel theory with supporting data to show that the low pH environment of maturating stage ameloblasts enhances their sensitivity to a given dose of $F^−$. Enamel formation is initiated in a neutral pH environment (secretory stage); however, the pH can fall to below 6.0 as most of the mineral precipitates (maturation stage). Low pH can facilitate entry of $F^−$ into cells. Here, we asked if $F^−$ was more toxic at low pH, as measured by increased cell stress and decreased cell function. Methodology/Principal Findings: Treatment of ameloblast-derived LS8 cells with $F^−$ at low pH reduced the threshold dose of $F^−$ required to phosphorylate stress-related proteins, PERK, eIF2α, JNK and c-jun. To assess protein secretion, LS8 cells were stably transduced with a secreted reporter, Gaussia luciferase, and secretion was quantified as a function of $F^−$ dose and pH. Luciferase secretion significantly decreased within 2 hr of $F^−$ treatment at low pH versus neutral pH, indicating increased functional toxicity. Rats given 100 ppm $F^−$ in their drinking water exhibited increased stress-mediated phosphorylation of eIF2α in maturation stage ameloblasts (pH<6.0) as compared to secretory stage ameloblasts (pH∼7.2). Intriguingly, $F^−$-treated rats demonstrated a striking decrease in transcripts expressed during the maturation stage of enamel development (Klk4 and Amtn). In contrast, the expression of secretory stage genes, AmelX, Ambn, Enam and Mmp20, was unaffected. Conclusions: The low pH environment of maturation stage ameloblasts facilitates the uptake of $F^−$, causing increased cell stress that compromises ameloblast function, resulting in dental fluorosis
