This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

This paper examines the qualities of situations wherein hybrid professionals in knowledge-intensive public organizations (KIPOs) vary in their displays of conflicting institutional logics. Specifically, it examines the situations when individual researchers vary in their displays of a traditionalist academic- and an academic performer logic.

Analysis is grounded in an institutional logics perspective and founded on qualitative interviews with university researchers recurrently exposed to performance measurement and management.

The findings show that individual researchers display a traditionalist academic- and an academic performer logic in situations of lower or higher “perceived control exposure” (i.e. perceptions of (not) being exposed to “what the performance measurement system wants to/can ‘see’”). In more detail, that a traditionalist academic logic is displayed more in situations of lower “perceived control exposure” whereas an academic performer logic is displayed comparatively more in situations of higher “perceived control exposure”.

These findings add insight into when there is room for resistance to pressures to perform in accordance with increasing performance measurement and when researchers more so tend to conform. While previous research has mostly studied such matters by emphasizing variation between researchers, this study points out the importance of situations of lower or higher “perceived control exposure”. Such insight is arguably also more broadly valuable since it adds to our understanding about hybridity of professionals in KIPOs and how to design and use performance measurement systems in relation to them.

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.

This study presents literature reviews for the period 2000–2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures.

This study indicates that the health literature has focused on individuals with direct exposure to pesticides, i.e. farmers, while the literature on preference valuation has focused on those with indirect exposure, i.e. consumers. The discussion highlights the need to clarify the rationale for regulating pesticides, the role of risk perceptions in benefit-cost analysis, and the importance of inter-disciplinary research in this area.

This study relates findings of different disciplines (health, economics, public policy) regarding pesticides, and identifies gaps for future research.

Exposure controlled projection lithography (ECPL) is an additive manufacturing process based on controlled UV photopolymerization. This paper aims to explore an advanced closed-loop control methodology to ECPL.

This paper proposes an evolutionary cycle to cycle (EC2C) control method, and started with a reduced order EC2C time control to control only the exposure time for given DMD bitmaps, which correspond to target 3D part cross-sections. A preliminary EC2C time control scheme was developed and followed by two types of EC2C time controllers based on two different parameter estimation methods, recursive least squares and L₁ norm minimization (L₁Min). Both algorithms were in an exponential weighted form, resulting in EWRLS and EWL₁Min, to weight more on recent data to reflect the current process dynamics.

EWRLS was found to outperform EWL₁Min in terms of computation speed and stability. The simulation study demonstrated that the proposed EC2C time control method was capable of adaptively tracking the ECPL process dynamics and updating online the model parameters with real-time measurements. It could control perfectly the exposure time for each bitmap, achieving the desired height for each layer and resulting in a total cured height conforming to the target 3D part height.

The accuracy of EC2C time control method relies heavily on fast and accurate measurement, and this research assumes availability of an adequate real-time metrology. Measurement errors are not considered in this paper and will be explored in future. Only simulation study was performed without physical experiments to verify the EC2C controller.

For implementation, a real-time measurement system needs to be developed and the EC2C control software needs to be programmed and interfaced with the physical system.

It concludes that EC2C control method is very promising for a physical implementation, and could be extended for the development of a more comprehensive closed-loop controller for both exposure time and intensity to improve the ECPL process precision and robustness.

Exposure to isocyanates was the leading cause of occupational asthma in the UK. Motor vehicle repair (MVR) bodyshop paint sprayers were at greatest risk, despite widespread use of air-fed breathing apparatus and ventilated booths. Most paint sprayers work in small and medium enterprises (SMEs). The purpose of the Health and Safety Executive (HSE) project, described in this paper, is to improve exposure control measures in at least 20 per cent of MVR bodyshops, and reduce the risk of occupational asthma. The paper aims to discuss this issue.

A three-stranded plan consisted of: Safety and Health Awareness Days (SHADs); workplace inspections; and third-party stakeholder communications. The impact of various parts of the project were evaluated.

Approximately 18 per cent of bodyshops in the UK attended one of 32 SHADs, following which over 90 per cent of delegates expressed an “intention to act” to improve exposure control measures. A local assessment showed that at least 50 per cent of bodyshops improved exposure control measures. An evaluation of 109 inspections found that enforcement action was taken at 40 per cent of visits. Third-party engagement produced a joint HSE-industry designed poster, new agreed guidance on spray booths and dissemination of SHAD material. Knowledge of booth clearance time has become widespread, and 85 per cent of booths now have pressure gauges. Biological monitoring data show that, post-SHAD, exposures were lower.

A sustained national project using clear, relevant, tested messages delivered via different routes, had a sector-wide impact in bodyshops. It is probable that the project has improved isocyanate exposure control in at least 20 per cent of bodyshops. The generic lessons could be applied to other widespread SME businesses.

As a tool to help compliance with relevant health and safety legislation, a cost‐effective method of risk assessing construction workers' exposure to hand‐arm vibration (HAV) is presented that allows larger numbers of workers to be evaluated, either as a stratified sample of a population or as a population where numbers are not prohibitive.

The method, developed and tested in the field with a national UK contractor, employs work study to collect exposure level data of workers undertaking real work and analyse these, to inform HAV management and risk control decisions.

The method benefits from economies of scale to efficiently risk assess large numbers of workers, without the need for specialist equipment or analysis software. It can be applied to sample strata defined by, for example, equipment used, types of work or classifications of worker.

Results add to the growing body of academic knowledge relating to construction worker HAV exposure and its management.

The method can easily be moulded to suit any type of construction organisation and help control cost associated with HAV legislation compliance.

Potential benefits of controlled HAV exposure include reduced incidence of (HAV induced) medical conditions and concomitant personal financial gains to society.

The method and context are novel. The methodology of work study and sampling in a broader sense are well established.

This study was conducted to find out the association between estrogen exposure and systemic lupus erythematosus (SLE) in Bangladeshi women.

A case-control study was carried out from January to December 2015 among 128 intervention cases and 128 age-matched control group participants to find out the association with estrogen exposure and development of SLE.

Case group participants were five times (OR 5.14, 95% CI 2.14–12.33), three times (OR 3.40, 95% CI 1.25–9.21) and four times (OR 4.00, 95% CI 1.45–11.00) more likely to receive different higher levels of education compared to the control group. Exposure to estrogen showed a positive association with the development of SLE. The case group (12.63 ± 1.61 years) had a lower age at menarche than that of the control group (13.31 ± 1.47 years; p < 0.001) and their proportion (62.6%) of using oral contraceptive pills were more than that of the control group (45.6%; p < 0.01). After controlling the effect of the positively associated variables, SLE patients were found two times (adjusted OR 2.26; 95% CI 1.29–3.95) more likely to use oral contraceptive pills than the control group. The case group was more (adjusted OR 0.771; 95% CI 0.642–0.927) prone to have an earlier age at menarche compared to the control group.

This study identified the association between estrogen exposure and SLE. Contraceptive pills should be used cautiously and both consumers and service providers need to be aware of their effects.

This study examined the impact of a brief seminar series on positive parenting (Selected Triple P) on behavioural and emotional problems in pre‐adolescent children and on inter‐parental conflict, parenting style, relationship quality, parental adjustment and parental confidence. Two hundred and forty‐four parents with children aged four to seven years were assigned to one of three conditions: (a) partial exposure condition involving attendance at a single introductory seminar; (b) full exposure (attendance at all three seminars); or (c) a waitlist control group. Analyses were completed for the 109 participants for whom full data were obtained. There was a significant reduction in parental reports of problem child behaviour and dysfunctional parenting styles with the introductory seminar alone. However, exposure to all three seminars was associated with significant improvements in all dysfunctional parenting styles and in the level of inter‐parental conflict. There were no significant differences between conditions at post‐intervention on parental reports of depression, anxiety, stress, relationship quality or parental confidence. This study provides preliminary support for the efficacy of a brief universal parenting intervention in improving child behaviour and parenting variables associated with the development and maintenance of child conduct problems. The findings also offer preliminary support for the notion that positive outcomes for both parents and children can be achieved through the delivery of brief preventive parenting interventions that require minimal time commitments from parents.

This paper considers the Control of Substances Hazardous to Health (COSHH) 1988 Regulations. In particular, it notes the Regulations' antecedents in UK legislation and European Directives, explains the key provisions of the Regulations and demonstrates the responsibilities of employers. The paper continues by examining the record of compliance with the Regulations and identifying the main reasons for the failure to implement. Conclusions are drawn on the effect of guidance and policing by the government advisory agency, and recommendations for targeting employers who have failed to comply are given.

This paper aims to measure exposures to airborne contaminants during three-dimensional (3-D) printing and post-processing tasks in an industrial workplace.

Contaminant concentrations were assessed using real-time particle number (0.007 to 1 µm) and total volatile organic compound (TVOC) monitors and thermal desorption tubes during various tasks at a manufacturing facility using fused deposition modeling (FDM^TM) 3-D printers. Personal exposures were measured for two workers using nanoparticle respiratory deposition samplers for metals and passive badges for specific VOCs.

Opening industrial-scale FDM^TM 3-D printer doors after printing, removing desktop FDM^TM 3-D printer covers during printing, acetone vapor polishing (AVP) and chloroform vapor polishing (CVP) tasks all resulted in transient increases in levels of submicrometer-scale particles and/or organic vapors, a portion of which enter the workers’ breathing zone, resulting in exposure. Personal exposure to quantifiable levels of metals in particles <300 nm were 0.02 mg/m³ for aluminum, chromium, copper, iron and titanium during FDM^TM printing. Personal exposures were 0.38 to 6.47 mg/m³ for acetone during AVP and 0.18 mg/m³ for chloroform during CVP.

Characterization of tasks provided insights on factors that influenced contaminant levels, and in turn exposures to various particles, metals < 300 nm and organic vapors. These concentration and exposure factors data are useful for identifying tasks and work processes to consider for implementation of new or improved control technologies to mitigate exposures in manufacturing facilities using FDM^TM 3-D printers.
