Into the Gray Zone: Examining Mutual Combat as a Defense to Domestic Assault

For offenses committed under Virginia’s assault and battery against a household or family member statute, the State should prosecute and punish in cases where both parties committed an assault and battery. Punishment, however, should consist of mainly individualized counseling or some other mitigated punishment for cases of mutual fighting

The Forgotten Expedition of the Michigan Polar Bears

The Michigan Polar Bear expedition saw Allied forces leading a controversial excursion into Northern Russia during the concluding years of World War I. Despite thousands of soldiers being sent to interfere with the Russian Civil War, the Polar Bear Expedition has been lost from collective memory. We publicly inquired about the expedition, then combined this research with a found scholarly consensus about the lack of cognizance relating to the events. This revealed a disconnect, which led us to inquire as to the nature and origin of its historical omission. Our primary sources of research focused on the oral histories of veterans located in the Joint Archives of Holland. After analyzing the first person accounts of the soldiers, followed in turn by the reaction of their respective communities, we created a detailed description of this expedition’s impact on the greater Holland area. Understanding this multi-generational oversight will bring forth a greater argument for the importance of people to continue teaching and learning about this significant piece of history

Application of six sigma methodology to reduce defects of a grinding process

Six Sigma is a data-driven leadership approach using specific tools and methodologies that lead to fact-based decision making. This paper deals with the application of the Six Sigma methodology in reducing defects in a fine grinding process of an automotive company in India. The DMAIC (Define–Measure–Analyse–Improve–Control) approach has been followed here to solve the underlying problem of reducing process variation and improving the process yield. This paper explores how a manufacturing process can use a systematic methodology to move towards world-class quality level. The application of the Six Sigma methodology resulted in reduction of defects in the fine grinding process from 16.6 to 1.19%. The DMAIC methodology has had a significant financial impact on the profitability of the company in terms of reduction in scrap cost, man-hour saving on rework and increased output. A saving of approximately US$2.4 million per annum was reported from this project

Six Sigma application for quality improvement of the pin insertion process

Six Sigma is a systematic and organized, client-oriented approach that aims to improve the performance and quality of processes, products and services using statistical techniques. This paper presents a case study performed in an automotive company that intends to reduce the defective units produced by an automatic process, the process of single pin insertion, using the DMAIC (Define, Measure, Analyze, Improve, Control) method that is a structured way to carried out Six Sigma projects. In this process, excessive pin insertion force on Printed Circuit Boards (PCBs) entailed high rejection costs and line stop times that affected the supply of the final assembly lines. Therefore, the application of Six Sigma had the purpose to increase the quantity of products produced well at the first time and to reduce the quality costs associated to the process. To this end, the problem was defined, measured and analyzed starting from the machine and the two products with the highest number of rejections. An exhaustive analysis to determine the root cause allowed concluding that the excessive force is generated by the interaction of three factors: the PCBs physical characteristics, the pins contact zone and the wear of the machine components. A set of improvements focused on these factors raised the quality levels of the process, making it more stable and with less variability, by reducing the insertion forces to values closer to the nominal value. Methods for keeping the process under control were also defined and implemented. The use of some quality tools and the Six Sigma methodology proved to be extremely positive since this has led to significant improvements in the quality of the pin insertion process.FCT - Fundação para a Ciência e a Tecnologia (UID/CEC/00319/2019

Case study in six sigma methadology : manufacturing quality improvement and guidence for managers

This article discusses the successful implementation of Six Sigma methodology in a high precision and critical process in the manufacture of automotive products. The Six Sigma define–measure–analyse–improve–control approach resulted in a reduction of tolerance-related problems and improved the first pass yield from 85% to 99.4%. Data were collected on all possible causes and regression analysis, hypothesis testing, Taguchi methods, classification and regression tree, etc. were used to analyse the data and draw conclusions. Implementation of Six Sigma methodology had a significant financial impact on the profitability of the company. An approximate saving of US$70,000 per annum was reported, which is in addition to the customer-facing benefits of improved quality on returns and sales. The project also had the benefit of allowing the company to learn useful messages that will guide future Six Sigma activities
