Made which to measure? Nineteenth century science and sporting bodies

The modification of bodies to enhance performance for competitive sporting purposes originated in the mid eighteenth century. Since then, ‘science’ has informed the discourses of sports training practices, but its influence has changed significantly, now being directive rather than merely being addressed in the ethos of training. Today, sports training practices often are associated with scientific research focussed on understanding the biological processes underpinning physical achievements. However, in the first two centuries of modern sport, science, rather than directing practice, was used as a legitimating, justifying discourse that served to empower training practices.

This paper, an exercise in historical anthropology, replaces conventional ethnographic data with the texts of sports training manuals, sports periodicals and medical journals to examine how these discourses represented the influence of science on the preparation of the body for competition. The focus on the nineteenth century is instructive because, first, physiological models at the century’s start were influenced by Galenic theory, but were underpinned by modern empirical science at its end. Second, from the 1860s, amateurism inspired a major rethinking of training; the ensuing contrast with the preparation of professional athletes illustrates how science was deployed in the making of nineteenth century sporting bodies.

Managing the donation service experience : a case study

This article examines the implications for nonprofits of managing donation exchanges using customer relationship management and service blueprinting. It presents a case study of one U.K.-based nonprofit and identifies a range of issues that might make managing donation service exchanges more complex than occurs in the for-profit setting. In particular, the fact that there are multiple simultaneous exchanges means that it may be difficult to separate donation processes from other organizational activities such as membership and campaigning. We explore the utility of service blueprinting in aiding the management of this complexity.

Effect of surface roughness of Ti, Zr, and TiZr on apatite precipitation from simulated body fluid

Some of the critical properties for a successful orthopedic or dental implant material are its biocompatibility and bioactivity. Pure titanium (Ti) and zirconium (Zr) are widely accepted as biocompatible metals, due to their non-toxicity. While the bioactivity of Ti and some Ti alloys has been extensively investigated, there is still insufficient data for Zr and titanium-zirconium (TiZr) alloys. In the present study, the bioactivity, that is, the apatite forming ability on the alkali and heat treated surfaces of Ti, Zr, and TiZr alloy in simulated body fluid (SBF), was studied. In particular, the effect of the surface roughness characteristics on the bioactivity was evaluated for the first time. The results indicate that the pretreated Ti, Zr and TiZr alloy could form apatite coating on their surfaces. It should be noted that the surface roughness also critically affected the bioactivity of these pretreated metallic samples. A surface morphology with an average roughness of approximately 0.6 microm led to the fastest apatite formation on the metal surfaces. This apatite layer on the metal surface is expected to bond to the surrounding bones directly after implantation.

Bone formation following implantation of titanium sponge rods into humeral osteotomies in dogs : a histological and histometrical study

Background: Titanium (Ti) is widely proven to enhance bone contact and growth on its surface. It is expected that bone defects could benefit from Ti to promote healing and to increase strength of the implanted area.

Purpose: The present study aimed at comparing the potential of porous Ti sponge rods with synthetic hydroxyapatite (HA) for the healing of bone defects in a canine model.

Material and Methods: Six mongrel dogs were submitted to three trephined osteotomies of 6.0 × 4.0 mm in one humerus and after 2 months another three osteotomies were performed in the contralateral humerus. A total of 36 defects were randomly filled either with Ti foam, particulate HA, or coagulum (control). The six animals were killed 4 months after the first surgery for histological and histometrical analysis.

Results: The Ti-foam surface was frequently found in intimate contact with new bone especially at the defect walls. Control sites showed higher amounts of newly formed bone at 2 months – Ti (p = 0.000) and HA (p = 0.009) – and 4 months when compared with Ti (p = 0.001). Differently from HA, the Ti foam was densely distributed across the defect area which rendered less space for bone growth in the latter's sites. The use of Ti foams or HA resulted in similar amounts of bone formation in both time intervals. Nevertheless, the presence of a Ti-foam rod preserved defect's marginal bone height as compared with control groups. Also, the Ti-foam group showed a more mature bone pattern at 4 months than HA sites.

Conclusion: The Ti foam exhibited good biocompatibility, and its application resulted in improved maintenance of bone height compared with control sites. The Ti foam in a rod design exhibited bone ingrowth properties suitable for further exploration in other experimental situations.

Quality of life of Australian family carers : implications for research, policy and practice

Abstract As part of an international,multicentered project, the burden of care, health, and subjective well-being experienced by select Australian family carers supporting a relative with disability at home were investigated. Some 448 family carers residing in New South Wales and Tasmania completed a battery of instruments, including a self-report demographic survey, the Family Caregiver Burden Inventory, the General Health Questionnaire, and the Personal Wellbeing Index. Respondents were predominantly females (mean
age = 48 years), married, and supporting a son or daughter with an intellectual disability (mean age = 18 years). Although caring for their family member was not perceived to be a burden, respondents reported notable limitations on their social networks and social activities. They reported higher levels of unemployment than would be expected for the general population and were over represented in lower income groups. They reported seriously low levels of mental health and personal well-being when compared with the general population. The findings revealed that this group of family carers were at high risk of social and economic disadvantage and at high risk of mental health challenges. Social policy makers and service providers should take these factors into account, both in the interests of promoting the health and well-being of the carers and considering the long-term needs of family members with disability who rely on family carers for daily support when designing services.

Fatty acid composition in tissues of mice fed diets containing conjugated linolenic acid and conjugated linoleic acid

The influence of 1% alpha-eleostearic acid (α-ESA, cis9,trans11,trans 13-18:3) and 1% punicic acid (PA, cis9,trans11,cis13-18:3) on fatty acid composition in mouse tissues was compared with conjugated linoleic acid (CLA, mixture of primarily cis9,trans11- and trans10,cis12-18:2) in the present study. The content (% total fatty acids) of 18:2n-6 was significantly reduced in the heart and adipose tissues, and total polyunsaturated fatty acids (PUFAs) and n-6 PUFA were significantly reduced in adipose tissue by α-ESA, PA and CLA feeding. The content of 22:6n-3 and total n-3 PUFA were significantly increased in the liver, kidney and heart by PA feeding, but not by α-ESA. In contrast to PA, supplementation with CLA significantly decreased 22:6n-3 in the liver, kidney and heart. The content of 20:4n-6 was significantly decreased in the liver and kidney by CLA feeding, but not by α-ESA and PA. The present results indicate that α-ESA, PA and CLA have differential effects on 22:6n-3 and 20:4n-6 content in mouse tissues.

The hidden martingale restriction in Gram-Charlier option prices

A hidden martingale restriction is developed for option pricing models based on Gram-Charlier expansions of the normal density function. The restriction is hidden behind a reduction in parameter space for the Gram-Charlier expansion coefficients. The resulting restriction is invisible in the option price.

The forecast quality of CBOE implied volatility indexes

We examine the forecast quality of Chicago Board Options Exchange (CBOE) implied volatility indexes based on the Nasdaq 100 and Standard and Poor's 100 and 500 stock indexes. We find that the forecast quality of CBOE implied volatilities for the S&P 100 (VXO) and S&P 500 (VIX) has improved since 1995. Implied volatilities for the Nasdaq 100 (VXN) appear to provide even higher quality forecasts of future volatility. We further find that attenuation biases induced by the econometric problem of errors in variables appear to have largely disappeared from CBOE volatility index data since 1995.
