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.

Role-based business process modeling deals with partitioning the universe of process modeling into different areas of concern by describing how business objects collaborate. A business object represents a concept of interest in the organization, such an activity or an entity, which can play multiple roles according to its behavior while interacting with other business objects. A specific business object collaboration can be expressed by the roles played by every participant in that scenario. This approach allows creating semantically richer business process models, and designing business objects where behavior is clearly separated and dependent on its usage context. Both of these results contribute to increase the understandability of process models and to enhance business object reuse.

Business process modeling with objects and roles

Finding suitable actors to perform specific activities is a common problem in knowledge-oriented organizations. To address this problem, this paper outlines the concepts required to represent organizational actor's skills and the services that are required by business process activities. These concepts are used within a marketplace-based model that enables dynamically managing actors and activities according to competence supply and demand.

In order to be able to plan, execute, and control its activities to achieve the desired results, it is essential that organizations tie together the academic knowledge and the operational experience by utilizing proven scientific theories in the organization executables. There are several theories about how to frame the models of corporate governance according to different perspectives; there are advantages and disadvantages in the adoption of each of them. The more or less complete dimension when related to the scope of each model is also an important aspect in its use and disclosure. The EX-ANTE and EX-POST model proposes a set of concepts that allow for the co-existence of mechanisms of access control and registration and validation, being the governance of the system based on four architectures: strategic, business, applications and technology. The model that the Portuguese Air Force uses for the definition of its annual flying hours regime includes five well-defined phases that may improve the level of coverage if the listed security mechanisms, control and audit, recommended in the Model EX-ANTE and EX-POST, are considered.

Adaptive Transform coding techniques for speech communication have recently received considerable attention. The basic concept of these methods is to divide the speech into frequency components by a suitable transform and then encode them using adaptive PCM. Examples of designs and performance of adaptive transform coders will be presented for bit rates in the range of 8 to 16 kbs.

An analysis/Synthesis framework for transform coding of speech

Granting the correct access between the agents and the artifacts is nowadays in the organizations agendas. The risk of allowing unauthorized accesses to critical information requires new solutions that are capable of dealing with a holistic perspective. Adaptive OACM refers to the capability of enforcing fine-grained access policies to business processes, services and information systems whenever facing changes, for instance, governance policies. This paper proposes an OACM ontology based in the RBAC, UUID, Rules and architectural model concepts. For exemplification purposes we instantiate the concepts of the ontology to an approval expense problem.
