Identifying gaps in perceived ability: Promoting exercise in young adults with disabilities

Aim: The purpose of this study was to describe the perceived ability in making health decisions regarding exercise and its congruence between young adults with disabilities and their parents. Methods: The study design used a mixed methods approach. The convenience sample consisted of (N = 10) young adults with disabilities and (N = 9) parents of young adults with disabilities. Qualitative data were gathered using a preliminary structured interview guide for young adults with disabilities consisting of several short answer questions. Quantitative data were gathered from the parents of young adults with disabilities by using Pender’s Health Promotion Questionnaire. Results: Data analysis began with simple descriptive statistics. The qualitative data, the structured interviews of the adolescents, were transcribed and evaluated for themes. The quantitative data, the parents’ questionnaires, were analyzed by aggregating data for frequencies and descriptive statistics. The qualitative data were then compared with the quantitative data to identify similarities and differences in perceptions. Conclusion: Comparison of responses among dyads provides insight about disparities that exist between what parents perceive their children with disabilities can decide about exercise and the children’s own perception about their abilities in making decisions regarding exercise

Facing the dragon: China policy in a new era

Recapping the dramatic Whitlam-Nixon openings to China of the 1970s—in which he participated—Ross Terrill’s new study finds themes for China policy today. Our Asia–Pacific region prospers, but the seas off China are not tranquil. American policies protect Australia, but they worry some Australians. Whitlam and Nixon cancelled decades of war in the Asia–Pacific, ushering in decades of astonishing economic growth for Australia, China and others. Can it last? Will the Chinese, who have much to lose from more war, accept give and take with Washington and Tokyo, or will the Middle Kingdom demand the middle position, squeezing its fourteen contiguous neighbours? With his dual perspective as both Australian and American citizen, Terrill examines the choices between idealism and realism, economic interests and security interests, and the benefits and risks of alliances. Looking forward, the paper assesses American staying power and the outlook for Beijing’s unprecedented mix of Leninism with consumerism, Australia’s future as a trading power, and Canberra’s ability to locate China within a wider Indo-Pacific vision that includes Indonesia, Japan, and India. Within six days in 1971, the Asia–Pacific changed as Zhou Enlai bargained with Whitlam and Nixon. Today six days of disaster on the Korean Peninsula could change our region again. But the essay hopes Washington, Beijing, and Canberra, interdependent as never before, may achieve further peace and prosperity for the Asia–Pacific. Between the poles of China and the US seeing each other as a “threat,” on one hand, and setting up a “G2”, Facing the Dragon foresees a peaceful, un-orchestrated China–US competition offering breathing room for Asia’s further progress

A comparative study of herbage intake, ingestive behaviour and diet selection, and effects of condensed tannins upon body and wool growth in lambs grazing Yorkshire fog (Holcus lanatus) and annual ryegrass (Lolium multiflorum) dominant swards

An experiment was carried out from August to early November 1994 to examine differences in diet selection, herbage intake, grazing behaviour and animal performance between weaned lambs rotationally grazing swards of annual ryegrass (Lolium multiflorum)/white clover (Trifolium repens) and Yorkshire fog (Holcus lanatus)/T. repens with or without Lotus corniculatus. There were four replicate groups of six lambs per treatment. The effects of condensed tannins (CT) on lamb production were assessed by twice-daily oral administration of 10g polyethylene glycol (PEG; molecular weight 4000) to half the lambs on each sward. The Lotus content of all swards was very low, and results are presented here for main sward comparisons meaned over lotus treatments. Overall mean estimates of pre-grazing herbage mass and sward surface height for the annual ryegrass and Yorkshire fog swards respectively, were 5820 v. 4360 +/- 190 kg DM/ha (P , P < 0.01) and liveweight gain (141 v. 120 +/- 4.3 g per lamb per day, P < 0.01), although differences in carcass weight (17.9 v. 18.2 +/- 0.3 kg) and FEC transformed values (9.6 v. 11.0 +/- 06 eggs/g fresh faeces) were not significant. The effects of CT on animal performance were greater in Yorkshire fog swards. CT had no significant effects on diet selection, herbage intake and grazing behaviour patterns

Transitioning by Degrees: Becoming a subject librarian through advanced education

This paper examines on librarian’s path from generalist librarian to subject specialist, with a focus on the value of additional advanced subject degrees in relationship to this work. Following the author’s career path from MLS to Business Librarian at a public university, the conversation also examines attitudes, perceptions, and frequency of additional advanced degrees in the literature

The spatial stability of a class of similarity solutions

The spatial stability of a class of exact similarity solutions of the Navier–Stokes equations whose longitudinal velocity is of the form xf′(y), where x is the streamwise coordinate and f′(y) is a function of the transverse, cross‐streamwise, coordinate y only, is determined. These similarity solutions correspond to the flow in an infinitely long channel or tube whose surface is either uniformly porous or moves with a velocity linear in x. Small perturbations to the streamwise velocity of the form x^λg′(y) are assumed, resulting in an eigenvalue problem for λ which is solved numerically. For the porous wall problem, it is shown that similarity solutions in which f′(y) is a monotonic function of y are spatially stable, while those that are not monotonic are spatially unstable. For the accelerating‐wall problem, the interpretation of the stability results is not unambiguous and two interpretations are offered. In one interpretation the conclusions are the same as for the porous problem—monotonic solutions are stable; the second interpretation is more restrictive in that some of the monotonic as well as the nonmonotonic solutions are unstable

Use of Diatomaceous Earth and Copper Oxide Wire Particles to Control Gastrointestinal Nematodes in Lambs

Abstract Anthelmintic resistance (AR) urges alternatives to control gastrointestinal nematodes (GIN). Copper oxide wire particles (COWP) are more efficacious when used with other dewormers and little is known on efficacy of diatomaceous earth (DE) to control gastrointestinal parasites. The objective was to examine the effects of DE and COWP on GIN control. Katahdin lambs (n = 32; ~150 d of age; 25.0 ± 1.8 kg) were randomly assigned to receive: 1) DE fed at an estimated 2% dry matter intake (with the assumption of moderate consumption of bermudagrass forage and provided supplement), 2) 1g COWP, 3) both 2% DE and 1g COWP, and 4) neither DE or COWP. Feces and blood were collected on d 0, 7, 14, 21 and 28 to determine fecal egg counts (FEC) and blood packed cell volume (PCV). Feces were cultured to determine GIN genera. Fecal egg counts were log transformed; data were analyzed as a 2 x 2 factorial arrangement using Proc Mixed of SAS with day as a repeated measurement. There was a mixed GIN population including 58% Haemonchus contortusand 30% Trichostrongylus spp.Fecal egg counts tended to be lower by d 28 in DE (175 eggs/g) than no DE (753 eggs/g) fed lambs (P = 0.09), but in general, were relatively low and no other differences among treatments detected. Packed cell volume tended to be higher in COWP than no COWP lambs by d 28 (P = 0.10), and no other differences detected. In conclusion, during a low GIN challenge, there may have been a small effect of DE on FEC, but no advantage observed in combination treatment

Methane emission by alpaca and sheep fed on lucerne hay or grazed on pastures of perennial ryegrass/white clover or birdsfoot trefoil

Based on the knowledge that alpaca (Lama pacos) have a lower fractional outflow rate of feed particles (particulate FOR) from their forestomach than sheep (San Martin 1987), the current study measured methane (CH4) production and other digestion parameters in these species in three successive experiments (1, 2 and 3): Experiment 1, lucerne hay fed indoors; Experiment 2, grazed on perennial ryegrass/white clover pasture (PRG/WC); and Experiment 3, grazed on birdsfoot trefoil (Lotus corniculatits) pasture (Lotus). Six male alpaca and six castrated Romney sheep were simultaneously and successively fed on the forages either ad libitium or at generous herbage allowances (grazing). CH4 production (g/day) (using the sulphur hexafluoride tracer technique), voluntary feed intake (VFI), diet quality, and protozoa counts and volatile fatty acid concentrations in samples of forestomach contents were determined. In addition, feed digestibility, energy and nitrogen (N) balances and microbial N supply from the forestomach (using purine derivatives excretion) were measured in Experiment 1. Diets selected by alpaca were of lower quality than those selected by sheep, and the voluntary gross energy intakes (GEI, MJ) per kg of liveweight(0.75) were consistently lower (P0.05) in their CH4 yields (% GEI) when fed on lucerne hay (5.1 v. 4.7), but alpaca had a higher CH4 yield when fed on PRG/WC (9.4 v. 7.5, P0.05) in diet N partition or microbial N yield, but alpaca had higher (P<0.05) neutral detergent fibre digestibility (0.478 v. 0.461) and lower (P<0.01) urinary energy losses (5.2 v. 5.8 % GEI) than sheep. It is suggested that differences between these species in forestomach particulate FOR might have been the underlying physiological mechanism responsible for the differences in CH4 yield, although the between-species differences in VFI and diet quality also had a major effect on it

Recent experiments on a small-angle/wide-angle X-ray scattering beam line at the ESRF

Recent results using a new combined small-angle/wide-angle X-ray scattering (SAXS/WAXS) beam line at the European Synchrotron Radiation Source (ESRF) will be presented. This beam line is specifically designed to be able to handle complicated sample environments required to perform time-resolved experiments mimicking processing conditions used in material science. Besides the attention that has been given to the interfacing of these sample environments to the beam line data acquisition system also the developments in detector technology will be discussed. The influence that a high count rate and low noise WAXS detector can have on the accuracy of experimental results in polymer crystallisation will be shown. It is shown that it is feasible to detect crystalline volume fractions as low as 10(-3)-10(-4) in polymeric systems
