Making Fine Powders ‐ Extremely fine and uniform particles, of 5–50 nanometers, have been produced by a process being developed at Battelle Pacific Northwest Laboratories. Researchers have used the technique to synthesize new, highly dispersed catalysts with a high surface area. It offers a way to make other products which have improved properties: ceramic ball bearings and gears which are stronger and more durable than those available today, and pigments for paints and inks.

This article describes the changes in the population of people with learning disabilities in Sheffield and the associated demand for specialist learning disability services, primary and acute health services and the wider public realm. It comments particularly on people with the most complex needs. The study to produce this data was in two parts: an analysis of changes in the overall number of people with a learning disability which included a projection of how the number might change over the next ten years, and an analysis of the health and support needs of young people with profound and multiple learning disabilities (PMLD), and how these might change in the future. The findings are compelling. The overall number of people with a learning disability in Sheffield increased by 25% in the 10 years from 1998 to 2008, the number of children and young people with a learning disability increased by nearly 120% and young people with PMLD were found to have an unprecedented level of health and social care need, which will increase further as they enter adulthood. The implications of the findings are discussed and suggestions for further research are offered.

The purpose of this paper is to describe trends in the age-standardised mortality rate and life expectancy of people with learning disabilities in Sheffield over three decades and to compare these with trends in the general population of England and Wales.

Data were extracted from the Sheffield Case Register and compared with data published by the Office for National Statistics for England and Wales.

There was a sustained reduction in age-standardised mortality rates and a sustained increase in life expectancy for people with intellectual disabilities over the 33-year period. These changes are extremely similar to those observed in the general population of England and Wales.

There is little evidence of any closing of the gap in age-standardised mortality rates or life expectancy between people with intellectual disabilities and the general population.

This article summarises recent work, commissioned by the Department of Health, which estimated the future need for health and social care services for adults with profound multiple learning disabilities (PMLD) in England. This estimation process involved four stages: identifying children with SEN associated with PMLD; adjusting for the effects of child mortality; estimating the number of adults with PMLD in England; and estimating net changes in the number of adults with PMLD in England. The overall findings suggest sustained and accelerating growth in the number of adults with PMLD in England over the time period 2009‐2026 and hence the need and demand for health and social care services for adults with PMLD.

Managerial decision-making is an area of interest to both academia and practitioners. Researchers found that managers often fail to manage complex decision-making tasks and system thinkers assert that generic structures known as systems archetypes help them to a great deal in handling such situations. In this paper, it is demonstrated that decision makers resort to lowering of goal (quick-fix) in order to resolve the gap between the goal and current reality in the “drifting the goals” systems archetype.

A real-life case study is taken up to highlight the pitfalls of “drifting the goals” systems archetype for a decision situation in the Indian two-wheeler industry. System dynamics modeling is made use of to obtain the results.

The decision makers fail to realize the pitfall of lowering the goal to resolve the gap between the goal and current reality. It is seen that, irrespective of current less-than-desirable performance, managers adopting corrective actions other than lowering of goals perform better in the long run. Further, it is demonstrated that extending the boundary and experimentation results in designing a better service system and setting benchmarks.

The best possible way to avoid the pitfall is to hold the vision and not lower the long term goal. The managers must be aware of the pitfalls beforehand.

Systems thinking is important in complex decision-making tasks. Managers need to embrace long-term perspective in decision-making. This paper demonstrates the value of systems thinking in terms of a case study on the “drifting the goals” systems archetype.

System dynamics is a whole-system modelling and learning approach, useful for tackling non-linear problems, such as sustainable urban development. The purpose of this paper is to review system dynamics applications in the simulation of sustainable urban development over a period from 2005 to 2017.

The analysis reveals that the number of applications of system dynamics modelling in the area of urban sustainable development increased in the analysed period. Research has changed its focus from the modelling of environmental problems to more complex models, portraying the multidimensional socio-economic processes that have an impact on the sustainability of urban development. Analysed case studies most often use the behaviour reproduction test for model validation, but without a unified approach. In most cases, modelling has been done in China, Germany and the USA, while urban development in the Eastern European countries, Africa and Latin America has not often been investigated. This paper indicates the knowledge gaps and suggests future research directions.

Papers that report the use of system dynamics modelling reveal a wide range of applications in urban sustainability. The analysis shows significant emphasis on environmental problems, while the interest for modelling social problems has been increasing during the last several years. Most of the modelled problems examine the sustainability of resources (land, water) and waste management, which are used for insights into the reasons for the system behaviour, forecasting future behaviour and policy testing.

The presented models were developed in most cases for the purpose of understanding the phenomena examined, as well as the future use of the models in policy planning. This brings us back to the need for greater stakeholder involvement, not only in the initial phase, but also during the whole modelling process, which could increase understanding, use and ownership of the models in the future, and thus increase their practical application.

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Reducing Level of Alcohol in Inks ‐ A medium‐sized US ink manufacturer recently needed to reduce the level of alcohol in its bases for water‐based inks. Ciba Geigy Pigments Division's Inks Technical Centre developed an improved formulation, containing half the alcohol of the previous one and 40 per cent more pigment to allow the ink producer to meet VOC limits and increase production efficiency, at no additional cost.
