...Journal ofEngineering and Technology Management, 10 (1993) 229-264 229 Elsevier Impacts of programmable manufacturing technology: A review of recent studies and contingency formulation Jeffrey K. Liker”, Ann Majchrzakb and Thomas Choi” “Industrial and Operations Engineering, University of Michigan, Ann Arbor, MI 48109, USA bZnstitute for Safety and Systems Management and Industrial and Systems Engineering, University of Southern California, Los Angeles, CA 90089, USA Abstract This paper reviews the literature on the social impacts of programmable manufacturing technology (PMT). Several perspectives on the social impact of technology are identified ranging from simple additive models that view technology as having a set of individual and independent causal impacts to a contingency perspective which views the impact of technology as dependent on technical and organizational characteristics. The paper statistically summarizes 30 empirical studies within the 1986-1990 period and finds common trends in findings as well as contradictory evidence. The common trends are that PMT tends to lead to more organic organizations, but also meets with negative employee attitudes, stress, and perceptions of reduced job security and mobility. The contradictory evidence is that most studies report simple, additive effects, while a substantial portion find that the impacts depend on a wide range of contingency variables. The authors argue that simplistic views of PMT as being...

...women in the United States die from heart disease each year. However, our knowledge base regarding CVD in African American (AA) women has not kept pace with the accumulation of data on white females. Thus, there is a deficit of information about this subgroup and the prevalence of CVD despite the fact that black women have more risk factors for CVD than do white women (3). The purpose of this paper is to review the subject of CVD in African American women and to focus upon four principal CVD categories: Coronary artery disease (CAD), hypertension, stroke, and congestive heart failure (CHF).The impact of gender and race on each of these entities will be examined in comparison to white women, and a determination will be made as to whether a different approach to the management of these disorders should be made based on ethnicity and sex. Coronary Artery Disease It has long been held that men have much more of a problem with CAD than women do; the belief has been that men are more susceptible to the disease, whereas...

...This led researchers to discover a new way to open arteries and reducing the rate of restenosis. They came up with stents which are metallic scaffolds of mesh which are inserted into the plaque filled artery to open it up and increase the flow of blood. Two initial studies were carried out to test the efficiency of stenting over BA the first was carried out by the North American Stent Restenosis Study. They looked at two factors the rate of restenosis and the rate of revascularization. Both rates were lower in patients receiving stents, rate of restenosis was 31.6% in stents vs. 42.1% in BA and the rate of revascularization was 10.2% in stents vs. 15.4% in BA. While these results were promising it was the results from the EU trial that convinced the FDA that this was a viable procedure and approved it as an elective operation in 1994. The results from the EU trial were as followed rate of restenosis was 22% in stents vs. 32% in BA and revascularization rates were 13.1% in stents vs. 22.9% in...

...or markets. As in the past, many organizations continue to address risk in “silos,” with the management of insurance, foreign exchange risk, operational risk, credit risk, and commodity risks each conducted as narrowly focused and fragmented activities. Under the new enterprise risk management (ERM) approach, all would function as parts of an integrated, strategic, and enterprise-wide system.1 And while risk management is coordinated with senior-level oversight, employees at all levels of the organization are encouraged to view risk management as an integral and ongoing part of their jobs. While there are theoretical arguments for corporate risk management,2 the main drivers for the implementation of ERM systems have been studies such as the Joint Australian/ New Zealand Standard for Risk Management, Committee of Sponsoring Organizations of the Treadway Commission (COSO) in the U.S. (in response to the control problems in the S&L industry), the Group of Thirty Report in the U.S. (following derivatives disasters in the early 1990s), CoCo (the Criteria of Control...

...International Journal of Materials, Mechanics and Manufacturing, Vol. 1, No. 2, May 2013 Hydro turbine Runner Design and Manufacturing Fatma Ayancik, Umut Aradag, Ece Ozkaya, Kutay Celebioglu, Ozgur Unver, and Selin Aradag Abstract—This research describes a methodology for the parametric design, computational fluid dynamics (CFD) aided analysis and manufacturing of a Francis type hydro turbine runner. A Francis type hydro turbine consists of five components which are volute, stay vanes, guide vanes, runner and draft tube. The hydraulic performance of the turbine depends on the shape of the components; especially on the shape of the runner blades. The design parameters for the other components are affected by the runner parameters directly. Runner geometry is more complex than the other parts of the turbine. Therefore; to obtain accurate results and meet hydraulic expectations, CFD analyses and advanced manufacturing tools are necessary for the design and manufacturing of the hydro turbine runner. The turbine runner design methodology developed is presented using an actual potential hydraulic power plant in Turkey. Index Terms—CFD, francis turbine, runner, design and manufacturing. I. INTRODUCTION Turbines are used for hydropower generation. There are basically two types of hydraulic turbines, the first one is impulse and the second one is reaction type turbines. Impulse turbines work based on momentum principle; while in the reaction type turbines, the flow is fully...

...It is rightly said that ' To Grab an Emerging Opportunity in its Bud, One Needs to Keep His Ears close to Ground '. Investment is also based on this methodology and to extract maximum returns out of an Investment, one needs to keep eyes and ears wide open to sense early any opportunity coming in the way. In the last report titled ' Comprehensive Analysis of Indian Starch & Starch Derivatives Sector ' a deep tabular and a brief theoretical analysis was presented of last 10 Years' Data to understand the scope and potential of Indian Starch & Starch Derivatives Sector. Now, in this report, we will present a deep theoretical argument based on the study of Chinese Starch & Starch Derivatives Sector over last two decades to understand the tremendous growth opportunity Indian Starch & Starch Derivatives Sector provides in the coming decade. It is worthwhile to note here that Indian Sector is almost a replica of Chinese Sector and Indian Sector, as at 2010, is at a stage where Chinese Sector was there in 1992. Over the time period between 1992-2009, Chinese Starch & Starch Derivatives Sector has grown more than 10 times and Indian Starch & Starch Derivatives Sector is bound to replicate such growth in the span of coming 10 years. We will also include in our analysis the consumption-trend of Sugar vis-a-vis Starch in China as well as India as Starch-based sweetners form 50 % of the marketsize of Chinese Starch & Starch Derivatives Sector whereas use of Starch-based sweetners as a substitute...

...Design of Goods and Services Product strategy and the design of goods and services are very important in the success of a firm or business. Some companies see these factors as the basis for success of an organization. Some firms choose to focus on only a few products within their organization in order to maximize success. With a limited number of products to focus on, it gives firms the opportunity to better these products. Product life cycles and strategies are studied and implemented to achieve a competitive advantage. The product life cycle includes the introductory phase (research, product development, process modification and enhancement), the growth phase (effective forecasting of capacity requirements), the maturity phase (competitors are established, reduction in options, improved cost control), and the decline phase (dying products are rid of unless they are still contributing to the firm). (Heizer, Render 2011). In order for strategies to be successful the life cycle of products must be studied, and adjusted over time. In order to maximize success with product, and service design it is important to understand the different variables that go into them, and make them work. Variables such as: value analysis, aesthetics, generation of new products, service design, and even joint ventures are just a few of the many variables that determine the success of goods and services. The articles examined explain the effects of these subjects in various markets. Value analysis...

...explore the applications of stem cells while avoiding the ethical problems associated with embryonic stem cell research (Seki & Fekuda, 2015). One intriguing area in stem cell research is the potential applications for them in the treatment of cardiac diseases. Studies have explored the potential uses for stem cells for the treatment of heart disease (Yamakawa & Ieda, 2015). Additionally, stem cells have been explored for the treatment of heart failure and myocardial infarction (Rasmussen, et al., 2013). Stem cells and how they may be used for the treatment of various cardiac diseases is an exciting topic and has the potential to change future approaches to the treatment. This paper will examine the applications and significance of stem cells in relation to these common cardiac pathologies. Heart disease is one of the leading causes of death in developed countries and currently there are few effective treatment options available (Yamakawa & Ieda, 2015). This it is important to research and make state of the art treatments available to address this issue. The use of stem cells may become an option for treatment of coronary artery disease (CAD). One approach has involved the use of endothelial progenitor cells (EPCs). In one study, EPCs were introduced into areas affected by ischemia and have been able to generate proliferation of new...
