The role of traditional analysis methods in improving complex socio-technical system safety has reached a ceiling, and thus systems theory has been utilised to support the investigations and countermeasures for road traffic accidents. As two widely applied systems accident analysis models, STAMP (systems theoretic accident model and process) and HFACS (human factors analysis and classification system) have their own advantages in accident analysis and safety improvement. Therefore, this study develops a new hybrid systems method integrating STAMP and HFACS for road traffic accident (SH-RTA), which can adopt HFACS to enhance the identification and analysis ability of STAMP for human factors and employ control concepts and elements of STAMP to cement the characteristic of HFACS. To illustrate the applicability of the hybrid method, a case study of '9·22' major road traffic accident in China is thoroughly analysed. Finally, preventive countermeasures and suggestions are presented. Practitioner Summary: This paper proposes a new hybrid systems method integrating STAMP and HFACS for road traffic accident. The new method reveals dysfunctional interactions within the parallel level and across levels, and identifies additional human and organisational factors. The recommendations for preventing road traffic accident are provided from higher levels of system. [ABSTRACT FROM AUTHOR] more...

Road transport is experiencing disruptive change from new first-of-a-kind technologies. While such technologies offer safety and operational benefits, they also pose new risks. It is critical to proactively identify risks during the design, development and testing of new technologies. The Systems Theoretic Accident Model and Processes (STAMP) method analyses the dynamic structure in place to manage safety risks. This study applied STAMP to develop a control structure model for emerging technologies in the Australian road transport system and identified control gaps. The control structure shows the actors responsible for managing risks associated with first-of-a-kind technologies and the existing control and feedback mechanisms. Gaps identified related to controls (e.g. legislation) and feedback mechanisms (e.g. monitoring for behavioural adaptation). The study provides an example of how STAMP can be used to identify control structure gaps requiring attention to support the safe introduction of new technologies. This paper considers emerging risks associated with new technologies in the road transport system. It demonstrates a novel approach using STAMP to identify gaps in control and feedback mechanisms within the existing control structure which should be addressed to mitigate risk.

Malnutrition threatens children worldwide. The objective of the current study was to highlight the role of nutritional screening, evaluate the effectiveness of nutritional intervention program, and whether nutritional supplements have surplus benefit. Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) was used to screen 3640 clinically stable 2–5 years old children recruited from the outpatient clinics, Children's Hospital, Ain Shams University. A total of 100 patients at high risk of malnutrition were enrolled. Full nutritional assessment was done and according to the distribution of the calories in the daily meal plan, the patients were randomly divided into two groups each comprised 50 patients. Group A received tailored nutritional dietary rehabilitation plan including dietary supplements, while Group B received only dietary advice. Anthropometric measurements, laboratory tests, as well as STAMP scoring were reassessed after the nutritional rehabilitation programs. Nutritional screening revealed that 5.14% were at high risk of malnutrition. Both studied groups showed significant improvement in caloric intake and all anthropometric measurements upon nutritional rehabilitation, except for the height z scores. Patients who received nutritional supplements showed significantly better changes regarding weight, BMI, caloric intake, and hemoglobin. Regarding STAMP categories during follow up, Group A had only 6% of the patients still in the high-risk category and 76% were at low risk compared to 14% high risk and only 54% were at low risk in Group B. Nutritional screening in pediatric outpatient facilities can lead to implementing prompt nutritional rehabilitation, which can reflect on the patients' overall health. Tailored nutritional plan can accomplish good response in terms of improvement of caloric intake, anthropometric measurements and laboratory parameters. Adding a nutritional supplement to the dietary plan during nutritional rehabilitation isn't a must but it ensures superior goal achievement. [ABSTRACT FROM AUTHOR] more...

The UK has seen little progress in reducing road death over the last decade and as a result, the government has been criticised by industry stakeholders for a lack of leadership, including the removal of national targets in 2011 and the devolution of powers to a municipal level. The aim of this paper is to understand how decision-making at a municipal level takes place from a systems perspective, using the case study of Cambridgeshire. Actors involved were mapped using a STAMP control structure analysis and highlighted a key role for formal and informal partnerships between local and national government agencies and non-government organisations at the same level in the control structure. The changing international context of the model for the UK is also discussed in relation to the UK's withdrawal from the European Union and provides a useful tool for future analysis of its effect on policy and decision-making. Practitioner summary: This paper uses a STAMP control structure analysis to understand how decision-making at a municipal level takes place from a systems perspective, using the case study of Cambridgeshire. It highlights a key role for formal and informal partnerships between organisations at the same level in the control structure.

Road safety strategies adopted worldwide have made significant progress in reducing road trauma, but have stagnated more recently. The situation in low- and middle-income countries is even worse with no significant decrease in fatality rates. Safety researchers have argued that adopting sociotechnical systems approach is necessary to make significant advancements and improvements. The aim of this study was to develop a control structure model of the Bangladesh road safety system by identifying the actors and organisations involved across the system. Expert stakeholders were identified and interviewed, and relevant information was gathered in order to generate the Systems Theoretic Accident Model and Process control structure model. Throughout the analysis of this model, differences in the control and feedback mechanisms of the system were identified, and road safety intervention recommendations were made. Future research should also predict potential risks within the system and propose proactive and preventative countermeasures. Practitioner summary: In this article, a Systems Theoretic Accident Model and Process control structure model of the Bangladesh road safety system is developed, and the involved actors are identified. Based on interviews and workshops with expert stakeholders, differences in the controls and feedback mechanisms in the system were identified, and road safety intervention recommendations were made.

The '8.12' Tianjin Port fire and explosion are an extraordinarily major accident that involved hazardous chemicals, resulting in 165 fatalities, 798 injuries, and a direct economic loss of 6.866 billion yuan. This study introduced causal analysis based on systems theoretic accident model and process (STAMP) (CAST) to identify the key controllers in the control structure, and the control and feedback relationships among them. By using CAST, this study not only identified the traditional human and organizational factors within the physical company which are responsible for the operation process, but also identified the outside factors within the public political structure which are responsible for the public safety and security. In this study, the safety and security of hazardous chemical accident are integrated into a unified framework in which the key difference between safety and security in the intention of the actors is reframed as a general loss prevention problem. This study shows the applicability of the CAST approach in the analysis of hazardous chemical accidents and provides different perspectives and methods to develop safety and security interventions in a hazardous chemical accident.

Changes to crewing configurations in commercial airlines are likely as a means of reducing operating costs. To consider the safety implications for a distributed crewing configuration, system theoretic accident model and processes (STAMP) was applied to a rapid decompression hazard. High level control structures for current operations and distributed crewing are presented. The CONOPS generated by STAMP-STPA for distributed crewing, and design constraints associated with unsafe control actions (UCAs) are offered to progress in the route to certification for distributed crewing, and improve safety in current operations. Control loops between stakeholders were created using system-theoretic process analysis (STPA). The factors leading to the Helios 255 incident demonstrated the redundancy that a ground station could offer without the risk of hypoxia, during a decompression incident. STPA analysis also highlighted initial UCAs that could occur within the hypothetical distributed crewing configuration, prompting consideration of design constraints and new CONOPS for ground station design. Practitioner Summary: SPO in commercial aircraft is likely as a means to reduce costs. This paper makes a case for distributed crewing using STAMP-STPA. Comparing current operations with a distributed crewing configuration, the redundancy offered by a ground station is demonstrated. Design constraints and new CONOPs for distributed crewing, and current operations are proposed. [ABSTRACT FROM AUTHOR] more...

The popularity of running as a form of exercise continues to increase dramatically worldwide. Alongside this participation growth is the burden of running-related injury (RRI). Over the past four decades, traditional scientific research applications have primarily attempted to isolate discrete risk factors for RRI using observational study designs as commonly used in public health epidemiology. Unfortunately, only very few randomised controlled trials have evaluated the efficacy associated with a well-specified RRI prevention intervention. Even though the knowledge about risk factors as generated in observational studies is valuable for better understanding why RRI develops, it nonetheless means that there remains a major knowledge gap about how best to prevent it, especially in a way that fully addresses all causal factors. Alongside the continuing use of traditional scientific approaches, a particular systems ergonomics methodology should also be considered in light of its potential to visualise the complete distance running system. This article adapts the Systems Theoretic Accident Mapping and Processes (STAMP) model to the RRI research prevention context. The direct application of STAMP might offer new knowledge about how to prevent RRI, such as exposing questions around the feasibility of adopting novel injury prevention interventions that do not directly target runners themselves.

Novel thin film optoelectronic devices containing both inorganic colloidal semiconductor quantum dots (QDs) and organic semiconductor thin films have been widely investigated in recent years for a variety of applications. Here, we review one of the most versatile and successful methods developed to integrate these two dissimilar material classes into a functional multilayered device: contact printing of colloidal QD films. Experimental details regarding the contact printing process are outlined, and the key advantages of this QD deposition method over other commonly encountered techniques are discussed. The use of tapping mode atomic force microscopy (AFM) to effectively characterize QD film morphology both on an elastomeric stamp (before contact printing) and as-transferred to the organic semiconductor receiving film (after contact printing) is also described. Finally, we offer suggestions for future efforts directed toward the goal of rapid, continuous QD deposition over larger substrates for the advancement of hybrid optoelectronic thin film devices.

The Human Factors Analysis and Classification System (HFACS), based upon Reason's model of human error in an organisational context, is currently the most widely used human factors accident analysis framework. However, it has been criticised for merely categorising accident data rather than analysing it. Previous research has established statistical associations between the levels and categories within HFACS but has not specified a mechanism by which one category influences subsequent behaviour. This paper extends the approach in two ways. Using the categories of control flaws derived from Leveson's Systems-Theoretical Accident Model and Processes (STAMP) approach, it describes the mechanisms by which categories within HFACS are associated with other categories lower in the organisational hierarchy. It also provides a mechanism by which active failures can promulgate across organisations. The revised methodology HFACS-STAMP is illustrated using the case study of the Uberlingen mid-air collision on 1 July 2002. [ABSTRACT FROM AUTHOR] more...

Rice discusses recent work in the Northwest of England to memorialize slavery and abolition in the context of Paul Gilroy's and Barnor Hesse's discussions of the legacy of empire and contemporary multiculturalism, and Paul Ricoeur's and Dominick LaCapra's more abstract disquisitions on the working of memory. He describes the importance of Lancaster historically in the slave trade and the historical amnesia that exists in the town, and outlines the development of the STAMP organization that aimed to counter these tendencies. He shows how the work of two artists, Kevin Dalton-Johnson and Lubaina Himid, have been instrumental in foregrounding Lancaster's involvement in the slave trade in the run up to the bicentennial celebrations in 2007. He uses published and unpublished interviews with the two artists to examine the contexts of memorialization, public and private memory, and community involvement, all of which contributed to their final pieces examining the legacy of slavery in the Northwest, nationally and internationally.

Abstract: Stamps, like any other non-book material such as banknotes, coins, posters, and maps, serve as recording media and source for information that illustrates the social, commercial, political, cultural, historical, and artistic aspects of a society in their own unique style. Using short and abstract text, color graphics and symbols on a limited surface area to communicate its contents is the key attribute that differentiates stamp from other non-book material. For this unique attribute, the stamp can be deemed both as a communication tool and a work of art. Conversely, stamp and other philatelic material in Turkey are largely regarded as collection materials rather than being a source for information. This study aims at performing a qualitative and quantitative analysis of the stamp collection at the National Library of Turkey as well as providing information on cataloging and maintaining of stamps and offering them to the attention of the public to stress the importance of stamps as a source for information rather than just a collection material.
