Perceptions of accident risk among on-track machine workers : an interview study
Although non-fatal injuries remain a frequent occurrence in safety-critical work, very few studies have examined the ways in which organisational systems and processes influence individual safety behaviour. Even fewer have explored the perceived factors contributing to accident risk using qualitative research methods. This short paper presents the initial results from a thematic analysis of ten interviews with On Track Machine (OTM) operatives. Issues arising from two key themes (fatigue, and safety communication and training) are briefly described. Implications, planned organisational response, and opportunities for further research are discussed
The use of building simulation within an architectural practice
This paper documents the development and implementation and use of simulation within an architectural practice and reports how its use facilitates the practice's commitment to Sustainable Design
Experience of using building simulation within the design process of an architectural practice
This paper documents work that follows on from a previous study [Morbitzer et al 2001] on the implementation of a simulation-tool into anarchitectural practice at outline design stage. Theuse of simulation is now pervasively and routinely undertaken by designers within the company toevaluate energy and environmental performance oftheir design concepts. The paper documents the changes to the interface, based on the feedback from designers. It includes a case study of how these improvements have impacted on the degree-of-use of the simulation tool by designers, the impact of the tool on the design process and the design outcome, a discussion on the development of the simulation tool, and the issues facing the architectural practice with use of simulation
Integration of building simulation into the design process of an architectural practice
A key barrier to the acceptance of simulation within building design has been identified as the fact that it is not fully integrated into the design process. The project described in this paper attempts to address this barrier by embedding modelling as a standard component of design practice procedures within an architectural practice
The Impact of a Community Awareness Strategy on Caregiver Treatment Seeking Behaviour and Use of Artemether-Lumefantrine for Febrile Children in Rural Kenya.
BACKGROUND: Access to prompt and effective treatment is the cornerstone for malaria control. Population Services International in collaboration with the Ministry of Health launched a malaria behaviour change communication intervention in Nyanza province, Kenya. The initiative aimed to improve: symptom recognition and prompt access to government health facilities for febrile children; effective treatment with the recommended first-line drug artemether-lumefantrine (AL) in public health facilities and adherence to the AL regimen. METHODS: Pre- and post-intervention cross-sectional household surveys were used to evaluate the impact of the intervention on prompt and correct use of AL for febrile children below five years of age. The primary outcome was the proportion of children below five years of age with fever in the last 14 days accessing AL within 48 hours of fever onset. RESULTS: There was an increase from 62.8% pre-intervention to 79.4% post-intervention (95% CI: 11.1, 22.1) in caregivers who reported seeking formal treatment promptly (on the same day, or next day) for their febrile children. However, there was a decrease in the use of government health facilities in the post-intervention period. There was a small increase in the proportion of children accessing AL within 48 hours of fever onset [18.4% vs 23.5% (0.1-10.0)]. CONCLUSION: The findings of this evaluation demonstrate that interventions that target only one sector may have a limited impact on improvements in prompt and effective treatment where multiple sources of treatments are sought for febrile illness. Additionally, the context in which an intervention is implemented is likely to influence the process and outcomes
Interventions for preventing non-melanoma skin cancers in high-risk groups
Background Some groups of people have a greater risk of developing common nonâmelanoma skin cancers (NMSC). Objectives To evaluate interventions for preventing NMSC in people at high risk of developing NMSC. Search methods We searched the Cochrane Skin Group Specialised Register (March 2007), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2007, MEDLINE (from 2003 to March 2007), EMBASE (from 2005 to March 2007), the metaRegister of Controlled Trials (February 2007). References from trials and reviews were also searched. Pharmaceutical companies were contacted for unpublished trials. Selection criteria Randomised controlled trials of adults and children at high risk of developing NMSC. Data collection and analysis Two review authors independently selected studies and assessed their methodological quality. Main results We identified 10 trials (7,229 participants) that assessed a variety of interventions. One trial found T4N5 liposome lotion significantly reduced the rate of appearance of new BCCs in people with xeroderma pigmentosum. One of three trials of renal transplant recipients showed a significantly reduced risk of new NMSCs when acitretin was compared to placebo (relative risk (RR) 0.22 95% confidence interval (CI) 0.06 to 0.90) and no significant difference in risk of adverse events in two trials (RR 1.80, 95% CI 0.70 to 4.61). In three trials conducted in people with a history of NMSC, the evidence was inconclusive for the development of BCCs for retinol or isoretinoin. However the risk of a new SCC in one trial (HR 1.79, 95% CI 1.16 to 2.76) and adverse events in another trial (RR 1.76, 95% CI 1.57 to 1.97) were significantly increased in the isotretinoin group compared with placebo. In one trial selenium showed a reduced risk of other types of cancer compared with placebo (RR 0.65, 95% CI 0.50 to 0.85) but also a significantly elevated risk of a new NMSC (HR 1.17, 95% CI 1.02 to 1.34). The evidence for one trial of betaâcarotene was inconclusive; and there was a trend towards fewer new NMSC in a trial of a reduced fat diet (RR 0.16, 95% CI 0.02 to 1.31), p = 0.09. Authors' conclusions Some preventative treatments may benefit people at high risk of developing NMSC, but the ability to draw firm conclusions is limited by small numbers of trials, often with one trial per intervention or with inconsistent results between studies
The Pine Needle, vol 5, no 4
Libraries and archives collect materials from different cultures and time periods to preserve and make available the historical record. As a result, materials such as those presented here may reflect sexist, misogynistic, abusive, racist, or discriminatory attitudes or actions that some may find disturbing, harmful, or difficult to view.
Both a humor and literary magazine, The Pine Needle was a University of Maine periodical that began publication in the fall of 1946, the first post-World War II semester that saw GIs returning to campus.
Unlike past UMaine student publications, The Needle celebrated the sexualization of co-eds and the use of drugs, tobacco, and alcohol by students. Outrage expressed by older alumni resulted stricter oversight of the magazine beginning in 1947. By 1949, the first wave of World War II GI\u27s were graduating and the restless, rebellious tone of The Needle began to shift as the threat of the Korean War loomed.
The spring 1951 House Party Issue cover features a pen-and-ink illustration by Zinas Zeke M. Mavodones, depicting a female Greek statue attempting to flee from a lecherous, predatory male Greek statue. The couple is surrounded by a pack of rabbits. In the background is a frat house bearing the insignia for Iota Phi Theta.
Mavodones was born in Portland, Maine in 1932 and following his graduation from the University of Maine, relocated to Poughkeepsie, New York, where he established a career in education and became active in the Hellenic Orthodox Church of the Assumption of the Virgin Mary. Mavodones became the coordinator of Adult Education in the Poughkeepsie Public School System and ultimately co-founded and served as the president of the Duchess [County] Association for Continuing Education
Design and Build of Reactor Simulator for Fission Surface Power Technology Demonstrator Unit
The Nuclear Systems Team at NASA Marshall Space Flight Center (MSFC) focuses on technology development for state of the art capability in non-nuclear testing of nuclear system and Space Nuclear Power for fission reactor systems for lunar and Mars surface power generation as well as radioisotope power systems for both spacecraft and surface applications. Currently being designed and developed is a reactor simulator (RxSim) for incorporation into the Technology Demonstrator Unit (TDU) for the Fission Surface Power System (FSPS) Program, which is supported by multiple national laboratories and NASA centers. The ultimate purpose of the RxSim is to provide heated NaK to a pair of Stirling engines in the TDU. The RxSim includes many different systems, components, and instrumentation that have been developed at MSFC while working with pumped NaK systems and in partnership with the national laboratories and NASA centers. The main components of the RxSim are a core, a pump, a heat exchanger (to mimic the thermal load of the Stirling engines), and a flow meter for tests at MSFC. When tested at NASA Glenn Research Center (GRC) the heat exchanger will be replaced with a Stirling power conversion engine. Additional components include storage reservoirs, expansion volumes, overflow catch tanks, safety and support hardware, instrumentation (temperature, pressure, flow) for data collection, and power supplies. This paper will discuss the design and current build status of the RxSim for delivery to GRC in early 2012
The pH of spray-dried blood meal does not influence nursery pig performance
Two studies were conducted to evaluate the effects of spray-dried blood meal and its
pH on nursery pig performance. Spray-dried
blood meal pH decreases as storage time
increases prior to spray drying. In Exp. 1,
addition of 2.5% spray-dried blood meal to
the diet improved ADG and ADFI in nursery
pigs (15.4 lb to 35.9 lb), but did not influence feed efficiency. In Exp. 2, the inclusion of 5% spray-dried blood meal improved feed efficiency without affecting ADG or ADFI. The pH (7.4 to 5.9 in Exp. 1 and 7.6 to 5.9 in Exp. 2) of the blood meal did not influence growth performance
Pharmacogenetic Testing for Clopidogrel Using the Rapid INFINITI Analyzer A Dose-Escalation Study
ObjectivesOur aim was to assess whether a higher clopidogrel maintenance dose has a greater antiplatelet effect in CYP2C19*2 allele carriers compared with noncarriers.BackgroundClopidogrel is a prodrug that is biotransformed by the cytochrome P450 enzymes CYP2C19, 2C9, and 3A4, 2B6, 1A2. The CYPC219*2 loss of function variant has been associated with a reduced antiplatelet response to clopidogrel and a 3-fold risk of stent thrombosis.MethodsForty patients on standard maintenance dosage clopidogrel (75 mg), for 9.4 ± 9.2 weeks, were enrolled into a dose escalation study. Platelet function was assessed at baseline and after 1 week of 150 mg once daily using the VerifyNow platelet function analyzer (Accumetrics Ltd., San Diego, California). Genomic DNA was hybridized to a BioFilmChip microarray on the INFINITI analyzer (AutoGenomics Inc., Carlsbad, California) and analyzed for the CYP19*2, *4, *17, and CYP2C9*2, *3 polymorphisms.ResultsPlatelet inhibition increased over 1 week, mean +8.6 ± 13.5% (p = 0.0003). Carriers of the CYP2C19*2 allele had significantly reduced platelet inhibition at baseline (median 18%, range 0% to 72%) compared with wildtype (wt) (median 59%, range 11% to 95%, p = 0.01) and at 1 week (p = 0.03). CYP2C19*2 allele carriers had an increase in platelet inhibition of (mean +9 ± 11%, p = 0.03) and reduction in platelet reactivity (mean â26 ± 38 platelet response unit, p = 0.04) with a higher dose. Together CYP2C19*2 and CYP2C9*3 loss of function carriers had a greater change in platelet inhibition with 150 mg daily than wt/wt (+10.9% vs. +0.7%, p = 0.04).ConclusionsIncreasing the dose of clopidogrel in patients with nonresponder polymorphisms can increase antiplatelet response. Personalizing clopidogrel dosing using pharmacogenomics may be an effective method of optimizing treatment
