According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

Building Leadership Effectiveness This program encourages leaders to develop practices that transform values into action, vision into realities, obstacles into innovations, and risks into rewards. Participants will be introduced to the five practices of exemplary leadership: modeling the way, inspiring a shared vision, challenging the process, enabling others to act, and encouraging the heart Coaching & Communicating for Performance Coaching & Communicating for Performance is a highly interactive program that will give supervisors and managers the opportunity to build skills that will enable them to share expectations and set objectives for employees, provide constructive feedback, more effectively engage in learning conversations, and coaching opportunities. Skillful Conflict Management for Leaders As a leader, it is important to understand conflict and be effective at conflict management because the way conflict is resolved becomes an integral component of our university’s culture. This series of conflict management sessions help leaders learn and put into practice effective strategies for managing conflict.

A maximum likelihood (ML) estimator is developed for determining time delay between signals received at two spatially separated sensors in the presence of uncorrelated noise. This ML estimator can be realized as a pair of receiver prefilters followed by a cross correlator. The time argument at which the correlator achieves a maximum is the delay estimate. The ML estimator is compared with several other proposed processors of similar form. Under certain conditions the ML estimator is shown to be identical to one proposed by Hannan and Thomson [10] and MacDonald and Schultheiss [21]. Qualitatively, the role of the prefilters is to accentuate the signal passed to the correlator at frequencies for which the signal-to-noise (S/N) ratio is highest and, simultaneously, to suppress the noise power. The same type of prefiltering is provided by the generalized Eckart filter, which maximizes the S/N ratio of the correlator output. For low S/N ratio, the ML estimator is shown to be equivalent to Eckart prefiltering.

This paper focuses on the class of speech enhancement systems which capitalize on the major importance of the short-time spectral amplitude (STSA) of the speech signal in its perception. A system which utilizes a minimum mean-square error (MMSE) STSA estimator is proposed and then compared with other widely used systems which are based on Wiener filtering and the "spectral subtraction" algorithm. In this paper we derive the MMSE STSA estimator, based on modeling speech and noise spectral components as statistically independent Gaussian random variables. We analyze the performance of the proposed STSA estimator and compare it with a STSA estimator derived from the Wiener estimator. We also examine the MMSE STSA estimator under uncertainty of signal presence in the noisy observations. In constructing the enhanced signal, the MMSE STSA estimator is combined with the complex exponential of the noisy phase. It is shown here that the latter is the MMSE estimator of the complex exponential of the original phase, which does not affect the STSA estimation. The proposed approach results in a significant reduction of the noise, and provides enhanced speech with colorless residual noise. The complexity of the proposed algorithm is approximately that of other systems in the discussed class.

The object of this paper is to use Agent-Based Simulation (ABS) to study the effects of cooperation in business organizational settings. To model the functioning of a business organization we have used an Enterprise Engineering approach named Design & Engineering Methodology for Organizations (DEMO). DEMO is based on the Ψ-theory which has the overall goal to extract the essence of an organization from its actual appearance. This theory assumes that an organization is a system of actors and incorporates four axioms. The operation axiom tells us that the implementation independent essence of an organization consists of actor roles and that the acts performed by the actor roles can be divided into two kinds: production acts and coordination acts. Another important axiom is the transaction axiom which states that coordination acts are performed as steps in universal patterns. Based on these assumptions and Game Theory principles of cooperation, a simple ABS was develop focused on studying the conditions that allow cooperation to emerge. By understanding these conditions, appropriate actions can be taken to foster the development of cooperation in such settings.

Agent-Based Simulation and Cooperation in Business Organizational Settings

This chapter aims at clarifying the notion of organization se If-awareness (OSA) as the state of a collective awareness of the enterprise system. We examine how such awareness arises from the collective action of the enterprise’s agents, while applying principles and methods of enterprise engineering and enterprise architecture. We find that value modeling is a vital enabler of OSA while bridging the gap between the teleological and ontological views of an enterprise.

Organizational Self-Awareness: A Matter of Value

An organization cannot function without knowing how much it produces and how much each product costs. The Portuguese Air Force is no exception, and so, determining the Cost per Flying Hour is essential for decision-making.

Cost Per Flying Hour – Use of Information from the Integrated Management System

Process orientation is a major concern nowadays. For this reason there have been great advances in business process modelling as a means to better understand and facilitate organizational operation and evolution. However, organizational functions like logistics, quality, finance, etc. still exist and strongly influence aspects like change processes, or the structuring of organizational units even if a “process culture” is established. This paper proposes a framework for integrating modelling, monitoring and learning aspects associated with the functional dimension of the enterprise. This framework is based on: (1) an ontology proposed (in another forthcoming paper) for the functional dimension of an organization; (2) the fundamental concepts: entity, role and activity, that are the base for current research work by other authors, on modelling other dimensions or concerns of an enterprise architecture. Also an example of application of the framework is presented as a proof of concept.
