This dissertation tries to explore those impact and implications aroused by postmodernist for contemporary organizations, those contemporary scenario (postmodern scenario) facing organizations, such as in search of possibilities, in need of simplicity, sensuous thinking, indeterminacy, a rapidly changing environment, discontinuity, ambiguity, boundarylessness, borderless, deconstruction, disintermediation, fragmentation, social class replaced by tribes, diversity, apprizing difference or otherness, hyperreality, and against governing rules, that will affect the strategic planning of organizations at present or in the coming future. In addition, this dissertation also tries to explore that currently or in the coming future how organizations rethink their strategies while facing postmodern scenario and its rigorous challenges, what forms, models or concepts of organization design that organizations can apply, and those managerial practices that organizations have ever executed. The research methodology adopted by this dissertation is primarily literature review and secondary data exploration. The target data including cases are focused on those conceptual strategic thinking. Those cases that are mainly complement to this dissertation are those distinguished multinational corporations (MNC) that have ever been transformed from manufacturing-oriented to service-oriented, or are able to prove partial strategic thinking reviewed in the dissertation. In the face of those thinking impact stirred by postmodernist and challenges resulted from postmodern managerial scenario, this dissertation concludes that organizations should review and rethink their assumption for the world, revisit the essence of strategy, picture and propose the big ideas, create or explore new value curves to avoid cruel face-to-face competition, explore new value positions and business models in the digital world, focus and develop core businesses and competence, build and manage communities, cultivate new types of royalty for those stakeholders partnering with organizations, utilize the relationships with and advantages from stakeholders, emphasize and advocate internal and external organizational integration and consistence and alignment for strategies, free from the cage of language and empower employees, keep exploring those organizational models or concepts that advocate or propose flexibility, networks of people, efficiency of communication, and spirit of democracy. In conclusion, this dissertation suggests that under global industrial value chains, multinational corporations should picture and propose the big ideas, create and explore new value curves, develop best-in-world core competence, form or dominate some internal or external communities or e-business communities, adopt strategy of time pacing for sound and moderate growth, reinforce cross-industry or cross-nation integration for organizations and strategies, keep reviewing and modifying any governing policy or rules, and keep searching and experimenting any latest possible and feasible models or concepts of organization. 後現代主義後現代組織工具理性語言戲局局部敘事超現實模糊無界限解構去中間化超競爭價值移轉策略失調策略反曲點主動惰性資源連續帶新價值曲線聯合經營價值網快速創業蜂巢式組織游牧式組織邦聯式組織多層面組織循環式組織實務社群 Postmodernism Postmodern Organization Instrument Rationality Language Game Local Narrative Hyperreality Ambiguity Boundarylessness Deconstruction Disintermediation Hypercompetition Value Migration Strategic Dissonance Strategic Inflection Point Active Inertia Resource Continuum New Value Curve Syndication Value Nets Fast Venturing The Cellular Organization The Nomadic Organization The Federation Organization The Multidimensional Organization The Circular Organization Communities of Practice time pacing
342	Rehabilitation of Exterior RC Beam-Column Joints using Web-Bonded FRP Sheets Mahini, Seyed Saeid Unknown Date (has links) In a Reinforced Concrete (RC) building subjected to lateral loads such as earthquake and wind pressure, the beam to column joints constitute one of the critical regions, especially the exterior ones, and they must be designed and detailed to dissipate large amounts of energy without a significant loss of, strength, stiffness and ductility. This would be achieved when the beam-column joints are designed in such a way that the plastic hinges form at a distance away from the column face and the joint region remain elastic. In existing frames, an easy and practical way to implement this behaviour following the accepted design philosophy of the strong-column weak-beam concept is the use a Fibre Reinforced Plastic (FRP) retrofitting system. In the case of damaged buildings, this can be achieved through a FRP repairing system. In the experimental part of this study, seven scaled down exterior subassemblies were tested under monotonic or cyclic loads. All specimens were designed following the strong-column weak-beam principal. The three categories selected for this investigation included the FRP-repaired and FRP-retrofitted specimens under monotonic loads and FRP-retrofitted specimen under cyclic loads. All repairing/retrofitting was performed using a new technique called a web-bonded FRP system, which was developed for the first time in the current study. On the basis of test results, it was concluded that the FRP repairing/retrofitting system can restore/upgrade the integrity of the joint, keeping/upgrading its strength, stiffness and ductility, and shifting the plastic hinges from the column face toward the beam in such a way that the joint remains elastic. In the analytical part of this study, a closed-form solution was developed in order to predict the physical behaviour of the repaired/retrofitted specimens. Firstly, an analytical model was developed to calculate the ultimate moment capacity of the web-bonded FRP sections considering two failure modes, FRP rupture and tension failure, followed by an extended formulation for estimating the beam-tip displacement. Based on the analytical model and the extended formulation, failure mechanisms of the test specimens were implemented into a computer program to facilitate the calculations. All seven subassemblies were analysed using this program, and the results were found to be in good agreement with those obtained from experimental study. Design curves were also developed to be used by practicing engineers. In the numerical part of this study, all specimens were analysed by a nonlinear finite element method using ANSYS software. Numerical analysis was performed for three purposes: to calculate the first yield load of the specimens in order to manage the tests; to investigate the ability of the web-bonded FRP system to relocate the plastic hinge from the column face toward the beam; and to calibrate and confirm the results obtained from the experiments. It was concluded that numerical analysis using ANSYS could be considered as a practical tool in the design of the web-bonded FRP beam-column joints.

343	Disruptive Transformations in Health Care: Technological Innovation and the Acute Care General Hospital Lucas, D. Pulane 24 April 2013 (has links) Advances in medical technology have altered the need for certain types of surgery to be performed in traditional inpatient hospital settings. Less invasive surgical procedures allow a growing number of medical treatments to take place on an outpatient basis. Hospitals face growing competition from ambulatory surgery centers (ASCs). The competitive threats posed by ASCs are important, given that inpatient surgery has been the cornerstone of hospital services for over a century. Additional research is needed to understand how surgical volume shifts between and within acute care general hospitals (ACGHs) and ASCs. This study investigates how medical technology within the hospital industry is changing medical services delivery. The main purposes of this study are to (1) test Clayton M. Christensen’s theory of disruptive innovation in health care, and (2) examine the effects of disruptive innovation on appendectomy, cholecystectomy, and bariatric surgery (ACBS) utilization. Disruptive innovation theory contends that advanced technology combined with innovative business models—located outside of traditional product markets or delivery systems—will produce simplified, quality products and services at lower costs with broader accessibility. Consequently, new markets will emerge, and conventional industry leaders will experience a loss of market share to “non-traditional” new entrants into the marketplace. The underlying assumption of this work is that ASCs (innovative business models) have adopted laparoscopy (innovative technology) and their unification has initiated disruptive innovation within the hospital industry. The disruptive effects have spawned shifts in surgical volumes from open to laparoscopic procedures, from inpatient to ambulatory settings, and from hospitals to ASCs. The research hypothesizes that: (1) there will be larger increases in the percentage of laparoscopic ACBS performed than open ACBS procedures; (2) ambulatory ACBS will experience larger percent increases than inpatient ACBS procedures; and (3) ASCs will experience larger percent increases than ACGHs. The study tracks the utilization of open, laparoscopic, inpatient and ambulatory ACBS. The research questions that guide the inquiry are: 1. How has ACBS utilization changed over this time? 2. Do ACGHs and ASCs differ in the utilization of ACBS? 3. How do states differ in the utilization of ACBS? 4. Do study findings support disruptive innovation theory in the hospital industry? The quantitative study employs a panel design using hospital discharge data from 2004 and 2009. The unit of analysis is the facility. The sampling frame is comprised of ACGHs and ASCs in Florida and Wisconsin. The study employs exploratory and confirmatory data analysis. This work finds that disruptive innovation theory is an effective model for assessing the hospital industry. The model provides a useful framework for analyzing the interplay between ACGHs and ASCs. While study findings did not support the stated hypotheses, the impact of government interventions into the competitive marketplace supports the claims of disruptive innovation theory. Regulations that intervened in the hospital industry facilitated interactions between ASCs and ACGHs, reducing the number of ASCs performing ACBS and altering the trajectory of ACBS volume by shifting surgeries from ASCs to ACGHs.
