Framework For Quantifying And Tailoring Complexity And Risk To Manage Uncertainty In Developing Complex Products And Systems

In recent years there has been a renewed interest in product complexity due its negative impact on launch performance. Research indicates that underestimating complexity is one of the most common errors repeated by new product development (NPD) teams. It was concluded that companies that successfully manage complexity can maintain a competitive advantage. This is particularly true of CoPS projects (Complex Products and Systems) which are defined as large-scale, high value, engineering intensive products and systems. Investment in CoPS projects continues to grow worldwide, with recent estimates placed at over $500B annually. In this research we present methods to improve the planning and coordination of complexity and risk in CoPS projects to support launch success. The methods are designed to be consistent with systems engineering practices which are commonly used in their development. The research proposes novel methods for the assessment, quantification, and management of development complexity and risk. The models are initiated from preliminary customer requirements so they may be implemented at the earliest point in the development process and yield the most significant cost savings and impact. The models presented are validated on a large-scale defense industry project and experimental case study example. The research demonstrates that development complexity and risk can be effectively quantified in the early development stages and used to align and tailor organizational resources to improve PD performance. The methods also provide the benefit of being implementable with little disruption to existing processes as they align closely with current industry practices

Carbon Monoxide Exposure and Human Health

The primary objective of this report is to provide detailed information on the health effects of carbon monoxide. With this information, the community can judge for itself what action is deemed necessary to maintain or improve the health of its residents

Product Pig Production Planner

There are many factors to consider when selecting a market hog for your 4-H project animal. Seek out reputable hog producers who produce hogs with high quality genetics and growth potential. Discuss the health and feeding program the hogs have received and follow these recommendations to assure your project animal can reach its growth potential

Systematic Approach to Rural Physician Service Planning and Development

The focus of this study is rural physician health care services. The primary objective is to develop methods which will allow community leaders to evaluate their communityrs ability to support a physician(s) or to allow a prospective physician to analyze a community's medical economic potential.Agricultural Economic

The PhD Project: How Successful Is It?

The PhD Project’s mission to diversify the work force by increasing the diversity of business school faculty is quite admirable, but is the Project successful? To gather insights toward responding to that question and to offer suggestions, we reviewed three of the Project’s objectives that relate most closely to minority doctoral students and faculty members. We examined the Project’s website, held discussions with Project staff members, and surveyed Project alumni. Among the myriad of PhD Project activities, the most important are its annual November conference for potential doctoral students and its annual minority doctoral student association meetings for each of five academic disciplines (accounting, finance, information systems, management and marketing). The annual conference attracts between 350 and 400 individuals from which about 10% enroll in doctoral programs each year. The doctoral student associations have over 1,400 members of which some 400 are current doctoral students and the others are faculty members. The Project is making significant progress toward accomplishing its mission and objectives. Areas where the Project could improve its accomplishments include identifying why those who have considered enrollment have not done so, placing greater emphasis on teaching and service at minority doctoral student association conferences, and strengthening mentoring relationships

High-frequency bistatic scattering by sub-bottom gas bubbles

The definitive version was published in Journal of the Acoustical Society of America 102 (1997): 806-814, doi:10.1121/1.419906.A previous study of high-frequency acoustic backscattering data collected at Eckernfoerde Bay, Germany revealed that scattering is mainly due to methane gas bubbles buried about a meter beneath the seafloor [Tang et al., J. Acoust. Soc. Am. 96, 2930–2936 (1994)]. A backscattering model was developed [Tang, Geo-Marine Lett. 16, 161–169 (1996)] where the gas bubbles were approximated by oblate spheroids. In this paper, a bistatic scattering model is proposed as an extension of the previously developed backscattering model. In this model, gas bubbles are again assumed to be oblate spheroids with varying aspect ratios and a single-scattering approximation is used. The model is compared to bistatic data acquired in Eckernfoerde Bay, Germany. In particular, the azimuthal dependence of the bistatic scattering strength predicted by the model is tested against experimental data and it is found that both the model and the bistatic scattering strength data exhibit a mild azimuthal dependence. Best agreement between model and data requires a 35% reduction in areal bubble density relative to that used in the backscattering model/data comparison. Possible reasons for this are discussed including multiple scattering effects.This work is supported by the Coastal Benthic Boundary Layer Special Research Program, Office of Navel Research Grant No. N00014-95-1-G904

"The Business Case for Racial Equity" Quantifies the Cost of Racism in the U.S.

Altarum Institute and the W.K. Kellogg Foundation (WKKF) released a report detailing the economic impact of racism, and the benefits of advancing racial equity as the demography of our nation continues to evolve

The Business Case for Racial Equity, 2013

Striving for racial equity -- a world where race is no longer a factor in the distribution of opportunity -- is a matter of social justice. But moving toward racial equity can generate significant economic returns as well. When people face barriers to achieving their full potential, the loss of talent, creativity, energy, and productivity is a burden not only for those disadvantaged, but for communities, businesses, governments, and the economy as a whole. Initial research on the magnitude of this burden in the United States (U.S.), as highlighted in this brief, reveals impacts in the trillions of dollars in lost earnings, avoidable public expenditures, and lost economic output
