Commitment planning reliability at an operational level is a key factor for improving project performance. In the last 15 years, the Last Planner System, a production planning and control system based on lean production principles, has improved commitment planning reliability in the construction industry. However, many construction decision makers continue to rely on their experience and intuition when planning their commitments, which hinders their reliability. The reliable commitment model (RCM) is proposed to improve commitment planning reliability at the operational level by using statistical models. RCM is an operational decision-making tool based on lean principles that supports short-term forecasting commitment planning using common-site information such as workers, buffers, and plans. RCM was tested in several case studies, demonstrating its production forecasting capabilities and its ability to help increase commitment planning reliability and improve project performance. RCM also supports workload and labor capacity matching decisions. RCM has the potential of becoming a useful production decision-making tool. © 2010 ASCE.

Background Previous research has shown that good footwear characteristics may reduce foot pain and foot-related disability in people with gout. The aim of this study was to determine the effect of good and poor footwear characteristics on plantar pressure and spatiotemporal parameters of gait in people with gout.Methods Thirty-six people with gout participated in a cross-sectional repeated measures study. Plantar pressure and spatiotemporal parameters were recorded in two shoe conditions: (1) the participants own footwear, and (2) either a new pair of walking shoes with good footwear characteristics (n = 21) or poor characteristics (n = 15). Differences between good and poor shoe groups compared to participants own shoes were also determined.Findings Compared to participant's own shoes, footwear with good characteristics significantly reduced peak pressure at metatarsal 3 and 5, reduced pressure time integrals beneath the heel and metatarsals 3 and 5 and increased pressure time integrals beneath the midfoot. The footwear with poor characteristics significantly increased peak pressure beneath the heel and lesser toes, reduced peak pressure at metatarsal 3 and reduced pressure time integrals in the midfoot compared to participants own shoes. Both good and poor footwear significantly increased walking velocity, step length, and stride length compared to participants own shoes.Interpretation Walking shoes with good footwear characteristics can influence plantar pressure values and encourage a more efficient heel to toe gait pattern in people with gout. These changes may contribute to the reduction in foot pain and foot-related problems in this population. © 2014 Elsevier Ltd. All rights reserved.

Sexually Transmitted Infections | Year: 2011

Infection with herpes simplex virus (HSV) is extremely common worldwide. In immunocompromised patients anogenital HSV disease may have atypical features and may be very severe. Treatment of aciclovir-resistant anogenital HSV disease is challenging, as resistance to alternative treatments may occur, and effective treatment generally involves intravenous therapy with relatively toxic agents such as foscarnet. This case report presents three immunocompromised patients with presumed aciclovir-resistant anogenital HSV disease who were successfully treated with topical imiquimod. Imiquimod promotes local immune activation, which results in resolution of viral lesions such as anogenital warts and HSV disease. It is convenient to use and avoids the necessity for intravenous treatment with substantial systemic toxicity. In addition, as the mode of action of imiquimod is related to immune stimulation rather than direct antiviral activity, it may be used repeatedly without resistance developing.

Extensive living roof substrate design to promote storm-water management while balancing structural load and maintaining >60% nonirrigated plant cover is investigated through linked laboratory and field experiments in Auckland, New Zealand. Setting quantifiable goals for the 2002 FLL guidelines and agronomic testing methods resulted in successful design of multiple nonproprietary substrates. Particle size distribution and quality control in the materials' supply chain are critical. Additional work is required to define a meaningful standard permeability test for living roofs. While the maximum water capacity guideline provides a conservative estimate for structural loading when a substrate is wet, it should not be used to predict storm-water retention. Agronomic measures of readily available water (10-100 kPa suction) plus plant stress water (100-1,500 kPa suction) provide a reasonable estimate for the maximum potential rainfall storage during individual storm events. Subject to Auckland's frequent rainfall, an extensive living roof with 70% v/v 4-10 mm pumice, 10% v/v 1-3 mm zeolite, and 20% organic matter at a 100-mm depth is recommended to maintain plants without irrigation (excluding drought conditions) and minimize weeds while preventing runoff from storms with less than 25 mm of rainfall. © 2012 American Society of Civil Engineers.

Pain | Year: 2015

Previous studies have shown that the outcomes of complex regional pain syndrome (CRPS) vary significantly between patients, but few studies have identified prognostic indicators. The aim of this study was to determine whether psychological factors are associated with recovery from recently onset CRPS amongst patients followed prospectively for 1 year. Sixty-six patients with CRPS (type 1) were recruited within 12 weeks of symptom onset and assessed immediately and at 6 and 12 months, during which time they received treatment as usual. At each assessment, the following were measured: signs and symptoms of CRPS, pain, disability, depression, anxiety, stress, pain-related fear, pain catastrophising, laterality task performance, body perception disturbance, and perceived ownership of the limb. Mixed-effects models for repeated measures were conducted to identify baseline variables associated with CRPS severity, pain, and disability over the 12 months. Results showed that scores for all 3 outcome variables improved over the study period. Males and those with lower levels of baseline pain and disability experienced the lowest CRPS severity scores over 12 months. Those with lower baseline anxiety and disability had the lowest pain intensity over the study period, and those with lower baseline pain and pain-related fear experienced the least disability over the 12 months. This suggests that anxiety, pain-related fear, and disability are associated with poorer outcomes in CRPS and could be considered as target variables for early treatment. The findings support the theory that CRPS represents an aberrant protective response to perceived threat of tissue injury. © 2015 International Association for the Study of Pain.

Purpose: We present a review of radionuclide imaging of tumour vascular physiology as it relates to angiogenesis. We focus on clinical trials in human subjects using PET and SPECT to evaluate tumour physiology, in particular blood flow and hypoxia. Methods: A systematic review of literature based on MEDLINE searches updated in February 2010 was performed. Results: Twenty-nine studies were identified for review: 14 dealt with 15O-water PET perfusion imaging, while 8 dealt with 18F-fluoromisonidazole PET hypoxia imaging. Five used SPECT methods. The studies varied widely in technical quality and reporting of methods. Conclusions: A subset of radionuclide methods offers accurate quantitative scientific observations on tumour vascular physiology of relevance to angiogenesis and its treatment. The relationship between cellular processes of angiogenesis and changing physiological function remains poorly defined. The promise of quantitative functional imaging at high specificity and low administered dose sustains interest in radionuclide methods. © 2010 Springer-Verlag.

Concerns are increasingly being raised in a number of countries in relation to the behavioural donor criteria and in particular the on-going permanent exclusion of men who have had sex with other men (MSM). The justification for this is broadly linked to the use of risk models. Generally current exclusion criteria are broadly defined and indirectly it might be argued that this leads to exclusion based on sexual orientation. Available data indicates compliance issues with the exclusion and recent reviews in Europe have recommended that further research in this area is needed before any change in the current permanent exclusion should be made. Lobby groups however promote a more targetted approach to behavioural criteria. Firm data to support this is however currently lacking.There are a number of possible approaches to assessing risk including the period since the activity took place, the number of partners in a given period, the type of sex act or a combination of these factors. Definition of an optimal approach will need to consider both the sensitivity and specificity of the intervention along with an assessment of ease and consistency of application. © 2011 The International Alliance for Biological Standardization.

Objectives: To characterise the subtypes of HLA-B27 in disease associated patients in the North Island of New Zealand. Methods: The subjects were 194 patients from the North Island of New Zealand. These had previously been positively tissue-typed for HLA-B27 owing to its associations with spondylarthropathies and anterior uveitis. The subjects gave informed consent to further testing of their samples, which were HLA-B27 subtyped using DNA sequence based typing. Statistical analysis of the data was performed using the chi square test with Yates' correction and Pearson's chi square test. Results: Nine different subtypes were described in this study. HLA-B*2701, B*2702, B*2704, B*2705, B*2706, B*2707, B*2709, B*2710 and B*2715. Within the study the prevalence of B*2704 was signifi cant in Asians (p<0.001) and the prevalence of B*2705 was signifi cant in Europeans (p<0.001). Of the three major subtypes identifi ed (B*2702, B*2704 and B*2705), none showed a statistical association to disease category. HLA-B27 homozygosity was not signifi cantly different to the healthy population (p=0.918). Conclusions: HLA-B27 subtypes were analysed in disease associated patients of the New Zealand North Island population. The subtypes found refl ected the HLA-B27 subtypes found in previous studies of the different ethnicities involved.

Background: High participation rates in sport and increasing recognition of how diet benefits athletic performance suggest sports settings may be ideal locations for promoting healthy eating. While research has demonstrated the effect of tobacco and alcohol sponsorship on consumption, particularly among youth, few studies have examined the extent or impact of food and beverage company sponsorship in sport. Studies using brand logos as a measure suggest unhealthy foods and beverages dominate sports sponsorship. However, as marketing goes beyond the use of brand livery, research examining how marketers support sponsorships that create brand associations encouraging consumer purchase is also required. This study aimed to identify the characteristics and extent of sponsorships and associated marketing by food and non-alcoholic beverage brands and companies through a case study of New Zealand sport. Methods. We conducted a systematic review of 308 websites of national and regional New Zealand sporting organisations to identify food and beverage sponsors, which were then classified as healthy or unhealthy using nutrient criteria for energy, fat, sodium and fibre levels. We interviewed 18 key informants from national and regional sporting organisations about sponsorships. Results: Food and beverage sponsorship of sport is not extensive in New Zealand. However, both healthy and unhealthy brands and companies do sponsor sport. Relatively few support their sponsorships with additional marketing. Interviews revealed that although many sports organisations felt concerned about associating themselves with unhealthy foods or beverages, others considered sponsorship income more important. Conclusions: While there is limited food and beverage sponsorship of New Zealand sport, unhealthy food and beverage brands and companies do sponsor sport. The few that use additional marketing activities create repeat exposure for their brands, many of which target children. The findings suggest policies that restrict sponsorship of sports by unhealthy food and beverage manufacturers may help limit children's exposure to unhealthy food marketing within New Zealand sports settings. Given the global nature of the food industry, the findings of this New Zealand case study may be relevant elsewhere. © 2013 Carter et al.; licensee BioMed Central Ltd.
