Management Localization And Performance Of Mncs In China : A Contingent Resource-Based View, Shengsheng Huang

Lingnan Theses

Although many foreign invested enterprises (FIEs) and consultants in China put the localization to a strategic level, management localization is still an emerging issue of human resource management in academic research. A few previous studies on management localization focused on the internal efficiency of the subsidiaries or parent-subsidiary relationship. The impact of management localization on the interaction between the subsidiary and local environment has received little attention. Moreover, localization lacks a consistent and valid definition. This thesis attempts to bridge the gap by systematically exploring the strategic impact of management localization. Management localization is defined as substituting expatriate managers with …

Stochastic Learning Feedback Hybrid Automata For Dynamic Power Management In Embedded Systems, T. Erbes, S. K. Shukla, Pushkin Kachroo

Electrical & Computer Engineering Faculty Research

Dynamic power management (DPM) refers to the strategies employed at system level to reduce energy expenditure (i.e. to prolong battery life) in embedded systems. The trade-off involved in DPM techniques is between the reductions of energy consumption and latency suffered by the tasks. Such trade-offs need to be decided at runtime, making DPM an on-line problem. We formulate DPM as a hybrid automaton control problem and integrate stochastic control. The control strategy is learnt dynamically using stochastic learning hybrid automata (SLHA) with feedback learning algorithms. Simulation-based experiments show the expediency of the feedback systems in stationary environments. Further experiments reveal …

Effect Of Microstructure And Alloying Elements On The Resistance Of Fastener Grade Steels To Hydrogen Assisted Cracking , Nicholas E. Nanninga

Dissertations, Master's Theses and Master's Reports - Open

Fastener grade steels with varying alloy contents and heat treatments were employed to measure changes in resistance to hydrogen assisted cracking. The testing procedure compared notched tension specimens fractured in air to threshold stress values obtained during hydrogen charging, utilizing a rising step load procedure. Bainitic structures improved resistance by 10-20% compared to tempered martensite structures. Dual phase steels with a tempered martensite matrix and 20% ferrite were more susceptible and notch sensitive. High strength, fully pearlitic structures showed an improvement in resistance. Carbon content, per se, had no effect on the resistance of steel to hydrogen assisted cracking. Chromium …

New Media Reading Strategy, Cheryl E. Ball

Dissertations, Master's Theses and Master's Reports - Open

This dissertation addresses the need for a strategy that will help readers new to new media texts interpret such texts. While scholars in multimodal and new media theory posit rubrics that offer ways to understand how designers use the materialities and media found in overtly designed, new media texts (see, e.g,, Wysocki, 2004a), these strategies do not account for how readers have to make meaning from those texts. In this dissertation, I discuss how these theories, such as Lev Manovich’s (2001) five principles for determining the new media potential of texts and Gunther Kress and Theo van Leeuwen’s (2001) four …

Performances Of Stochastic Approaches In Generating Low Streamflow Data For Drought Analysis

Journal of Spatial Hydrology

This study analyzed the monthly-minimum daily discharge data of each month from three gauge stations on Cekerek Stream for forecasting using stochastic approaches. Initially non- parametric test (Mann-Kendall) was used to identify the trend during study period. The two approaches of stochastic modeling, ARIMA and Thomas-Fiering models, were used to simulate the monthly-minimum daily discharge data of each month. The error estimates (RMSE and MAE) of forecasts from both approaches were compared to identify the most suitable approach for reliable forecast. The two error estimates calculated for two approaches indicate that ARIMA model appear to be slightly better than Thomas-Fiering. …

Building Zion: The Latter-Day Saint Legacy Of Urban Planning, Craig D. Galli

BYU Studies

As with the founding of Plymouth Colony, distinctive historical circumstances and theological beliefs converged to motivate early Latter-day Saint community builders. While the historic roots of Salt Lake City are well known to virtually every grade school student in Utah and to Church members around the world, aspects of our remarkable legacy of urban and transportation planning remain obscure. The physical design and community values underlying early attempts to build Zion provide useful perspective and inspiration as today's community leaders now grapple with managing urban growth along Utah's Wasatch Front (from Brigham City to Nephi and Grantsville to Kamas) and …

Applying Cost-Benefit To Past Decisions: Was Environmental Protection Ever A Good Idea?, Lisa Heinzerling, Frank Ackerman, Rachel Massey

Georgetown Law Faculty Publications and Other Works

In this Article, however, we do not mount a critique from outside the technique of cost-benefit analysis. Instead, we examine an argument that proponents of cost-benefit analysis have offered as a linchpin of the case for cost-benefit: that this technique is neither anti- nor pro-regulatory, but rather a neutral tool for evaluating public policy. In making this argument, these proponents have often invoked the use of cost-benefit analysis to support previous regulatory decisions (their favorite example involves the phase down of lead in gasoline, which we shall shortly discuss) as a sign that this technique can be used to support …
