Reliability estimation based on operational data of manufacturing systems
Maintenance management has a direct influence on equipment reliability and safety. However, a large portion of traditional maintenance models and reliability analysis methods usually assumes that only perfect maintenance is performed on the system and the system will restore to as good as new regardless of the kind of preventive maintenance work-order that is performed. This is not practical in reality and may result in an inaccurate parametric estimation. The research objective of this paper is to develop a maximum likelihood estimation method to obtain more accurately estimated parameters based on the operational data of manufacturing systems, taking into consideration the difference between perfect and imperfect maintenance work-orders. Weibull distribution is specifically studied for this purpose. A practical case study based on industrial operational data from an automotive assembly line is performed to illustrate the implementation and efficiency of the proposed reliability estimation method.

The Conservative Governments’ record on social policy from May 2015 to pre-COVID 2020: policies, spending and outcomes. An assessment of social policies and social inequalities on the eve of the COVID-19 pandemic
This overview report provides an assessment of social policy developments under the three Conservative Governments that were in power between May 2015 and the eve of the COVID-19 pandemic in early 2020. The report provides a comprehensive examination of developments in ten major areas of social policy (social security; employment; early childhood; compulsory school age education; higher education; health; social care; physical safety and security; homelessness / complex needs; and social mobility) over this period. In assessing social policies and social inequalities on the eve of the pandemic, we identify five key cross-cutting major weaknesses and structural limitations of the welfare state and public services. In assessing outcomes across different social policy areas, we find there is overwhelming evidence that a break in social progress across multiple critical areas of life had already occurred prior to the public health emergency and the economic and social shocks that it triggered. Across the social policy areas that we examine, many key indicators of social progress had already slowed down, stalled or gone into reverse prior to the onset of the COVID-19 pandemic. Finally, looking forward, and as an input into broader discussions and debates about what is needed as the country transitions into the recovery phase from COVID-19, we set out five key cross-cutting social policy challenges for the 2020s

Video-based Simulations: Considerations for Teaching Students with Developmental Disabilities
The use of video-based multimedia simulations for teaching functional skills to persons with developmental disabilities remains an unexplored application of technology for this group. This article examines the historical literature in this area, and discusses future considerations, design issues, and implications of using multimedia simulations. Implementation issues are presented, and suggestions regarding design, development, and application of multimedia simulations are offered. Considerations address the importance of appropriate role modeling and the combination of video-based simulation and in vivo training to foster generalization and maintenance in the context of transition to the real world.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
