Responsible management: Engaging moral reflexive practice through threshold conceptsHibbert, P., Cunliffe, Ann L. 2013 December 1919 (has links)
Yes / In this conceptual paper we argue that, to date, principles of responsible management have not impacted practice as anticipated because of a disconnect between knowledge and practice. This disconnect means that an awareness of ethical concerns, by itself, does not help students take personal responsibility for their actions. We suggest that an abstract knowledge of principles has to be supplemented by an engaged understanding of the responsibility of managers and leaders to actively challenge irresponsible practices. We argue that a form of moral reflexive practice drawing on an understanding of threshold concepts is central to responsible management, and provides a gateway to transformative learning. Our conceptual argument leads to implications for management and professional education.

An Examination of the Relationship between Oil Price and Income in Taiwan by Threshold Vector Error Correction Model.Wang, Yu-wun 27 June 2007 (has links)
Since petroleum is a kind of exhaustive resource, it can not be
regenerated after being consumed. And petroleum is distributed
extremely uneven in the world, more than half of petroleum is
distributed in the Middle East area. In the recent years, the oil
price was so fluctuating and broke the record again and again.
However, the productivity of petroleum in Taiwan is very low and
we are a price taker. So it turns to be important that how the
oil price affects the economy. According to Economics, high oil
price often causes the staginflation. In the purpose of this study
we examine the long run relationship between oil price and
personal income in Taiwan by cointegration theory. And we find
that there indeed exists a negative longrun relationship. In
addition, we consider a nonlinear model, Threshold Vector Error
Correction Model, to test a threhold effect in the long run
relationship between variables. Finally we have a result that
there is a threshold cointegrating relationship between the oil
price and personal income in Taiwan.

NANOPIPELINED THRESHOLD SYNTHESIS USING GATE REPLICATIONPierce, Luke 01 August 2011 (has links)
Threshold logic gates allow for complex multi-input functions to be implemented using a single gate reducing the power and area of the circuit. Clocked based threshold gates have the additional advantage of its capability of being nanopipelined to increase network throughput. To produce a threshold network the proposed algorithm accepts a traditional algebraic boolean network as an input and resynthesizes it into a nanopipelined threshold logic network. The algorithm is the first to our knowledge that synthesizes in a manner to not only minimize the number of clusters produced from synthesizing the algebraic boolean network but also to minimize associated buffer insertion overhead in producing a clocked threshold gate network.

Minimizing and exploiting leakage in VLSIJayakumar, Nikhil 15 May 2009 (has links)
Power consumption of VLSI (Very Large Scale Integrated) circuits has been growing at
an alarmingly rapid rate. This increase in power consumption, coupled with the increasing
demand for portable/hand-held electronics, has made power consumption a dominant
concern in the design of VLSI circuits today. Traditionally dynamic (switching) power has
dominated the total power consumption of VLSI circuits. However, due to process scaling
trends, leakage power has now become a major component of the total power consumption
in VLSI circuits. This dissertation explores techniques to reduce leakage, as well as
techniques to exploit leakage currents through the use of sub-threshold circuits.
This dissertation consists of two studies. In the first study, techniques to reduce leakage
are presented. These include a low leakage ASIC design methodology that uses high
VT sleep transistors selectively, a methodology that combines input vector control and circuit
modification, and a scheme to find the optimum reverse body bias voltage to minimize
leakage.
As the minimum feature size of VLSI fabrication processes continues to shrink with
each successive process generation (along with the value of supply voltage and therefore the
threshold voltage of the devices), leakage currents increase exponentially. Leakage currents
are hence seen as a necessary evil in traditional VLSI design methodologies. We present
an approach to turn this problem into an opportunity. In the second study in this dissertation,
we attempt to exploit leakage currents to perform computation. We use sub-threshold
digital circuits and come up with ways to get around some of the pitfalls associated with sub-threshold circuit design. These include a technique that uses body biasing adaptively
to compensate for Process, Voltage and Temperature (PVT) variations, a design approach
that uses asynchronous micro-pipelined Network of Programmable Logic Arrays (NPLAs)
to help improve the throughput of sub-threshold designs, and a method to find the optimum
supply voltage that minimizes energy consumption in a circuit.

A Examination of the Relationship between 90-days and 180-days Commerical Paper rate Application by Threshold CointegrationLin, Yuan-Ching 27 June 2007 (has links)
This paper uses a two-regime vector error-correction with a single cointegrating vector and a threshold in the error-correction term introduced by Hansen and Seo(2002). We propose a SupLM test for the presence of a threshold. We derive the asymptotic distribution and show how to simulate asymptotic critical region. Applying our methods to the 90-days and 180-days Commercial Paper rate, we find that there are an apparent threshold effect and inconsistent behaviors in the long-run equilibrium process.

Non-Linear Mechanisms of Exchange Rate Pass-Through For TaiwanTsai, Yi-shiuan 28 June 2007 (has links)
Taiwan is usually considered as a small open economy. Trade and exchange rate policies in Taiwan have substantially changed since the mid-1980s. Not only has trade been liberalized, but exchange rates of the New Taiwan Dollar(NTD) were also allowed to fluctuate. This paper applies the Threshold Regression Model that puted forward of Cancer and Hansen (2004) and combines the expectation-augmented Phillips curve with a threshold for the pass-through. The paper examines whether the short-run magnitude of the pass-through is affected by the business cycle, direction and magnitude of the exchange rate change. For that purpose, two variables are tested as thresholds: (1)output gap, (2)exchange rate change. The results indicate that the short-run pass-through is higher when the economy is booming, as well as the exchange rate depreciates above some threshold. And they have important implications for monetary policy and are possibly related to pricing-to-market behavior and menu costs of price a djustment.

IC Design and Implementation of 6-T SRAM Cell Using Dual Threshold Voltage Transistors and Low Power Quenchersand Programmable PLL-Based Frequency MultiplierChen, Kuo-Long 26 June 2002 (has links)
Two different topics associated with their respective applications are proposed in this thesis. The first topic is the implementation of a 6-T SRAM cell using dual threshold voltage transistors and low power quenchers. We proposed a SRAM cell with dual threshold voltage transistors. The advantages of such a design is to reduce the access time and maintain data retention at the same time. Besides, the unwanted oscillation of the output data lines caused by large currents is reduced by adding two back-to-back quenchers.
The second topic is focused on the implementation of a programmable PLL-based frequency multiplier. Using the method of a phase-locked loop and a programmable divisor to implement a frequency multiplier. ¢Ï synchronous clock signal can be generated by the proposed design. It can also be used in wireless communication systems, e.g. local oscillators.

Essays on price dynamics, discovery, and dynamic threshold effects among energy spot markets in North AmericaPark, Haesun 01 November 2005 (has links)
Given the role electricity and natural gas sectors play in the North American economy,
an understanding of how markets for these commodities interact is important. This
dissertation independently characterizes the price dynamics of major electricity and
natural gas spot markets in North America by combining directed acyclic graphs with
time series analyses. Furthermore, the dissertation explores a generalization of price
difference bands associated with the law of one price.
Interdependencies among 11 major electricity spot markets are examined in
Chapter II using a vector autoregression model. Results suggest that the relationships
between the markets vary by time. Western markets are separated from the eastern
markets and the Electricity Reliability Council of Texas. At longer time horizons these
separations disappear. Palo Verde is the important spot market in the west for price
discovery. Southwest Power Pool is the dominant market in Eastern Interconnected
System for price discovery.
Interdependencies among eight major natural gas spot markets are investigated
using a vector error correction model and the Greedy Equivalence Search Algorithm in
Chapter III. Findings suggest that the eight price series are tied together through sixlong-run cointegration relationships, supporting the argument that the natural gas market
has developed into a single integrated market in North America since deregulation.
Results indicate that price discovery tends to occur in the excess consuming regions and
move to the excess producing regions. Across North America, the U.S. Midwest region,
represented by the Chicago spot market, is the most important for price discovery. The
Ellisburg-Leidy Hub in Pennsylvania and Malin Hub in Oregon are important for eastern
and western markets.
In Chapter IV, a threshold vector error correction model is applied to the natural
gas markets to examine nonlinearities in adjustments to the law of one price. Results
show that there are nonlinear adjustments to the law of one price in seven pair-wise
markets. Four alternative cases for the law of one price are presented as a theoretical
background. A methodology is developed for finding a threshold cointegration model
that accounts for seasonality in the threshold levels. Results indicate that dynamic
threshold effects vary depending on geographical location and whether the markets are
excess producing or excess consuming markets.
