Principles of Multimedia News Systems for Business Applications

In the past few years considerable demand for business oriented multimedia information systems has developed. A multimedia information system is one that can create, import, integrate, store, retrieve, edit, and delete two or more types of media materials in digital form, such as audio, image, full-motion video, and text information. Multimedia information systems play a central role in many business activities. They represent a very special class complex computing systems. This paper surveys a special type of multimedia information systems: multimedia news systems. Multimedia news systems deal with architectures to manage complex multimedia news databases, online presentation and distribution services or the integration of several existing services to meta-services using intelligent news retrieval engines. The leading presentation platform in multimedia news presentation is news networks providing television services and Internet content distribution. The primary focus is on advanced multimedia news systems infrastructure, document standards, application architecture and principles for multimedia news on the Web that suggest long-term trends in this increasingly important area.multimedia, information systems, business applications

Measuring the Performance of Corporate Knowledge Management Systems

Whereas knowledge management systems (KMS) continues to gain popularity as a corporate most advanced information systems, the acceptance of standardized KMS assessment approaches has logged. Developing metrics to assess a corporate KMS is inherently problematic due to the intangible nature of knowledge-based resources, and for the fact that measurement is a precursor to improvement. This is true for knowledge management capabilities of an organization. Nonetheless, assessment is of vital importance for valuation purposes as well as to help managers determine whether particular KMS are effective working. The main focus of this paper is to explain the value of knowledge management and provide a general overview of measurement approaches. Finally, developing an improved measurement system for corporate KMS is considered the key to the competitive success of the organization.Corporate Knowledge, Knowledge Management Systems, Measuring the Performance

This paper discusses the convergence of thinking among various disciplines in analysis and design methodologies, and describes the key elements of the new-emerged performance support engineering development methodology. These are important for designing web-based systems, information systems, and knowledge management systems in higher education.performance-centered systems, web-besd systems, information systems, knowledge management systems, methodology, higher education

Outsourcing the Business Services

The nowadays international market of outsourcing services is relatively mature and with age comes wisdom ... Thus, on a grown market, choosing to outsource services can not only be justified by the strive to reduce costs but it aims to meeting more advanced objectives as accurate alignment with business strategies of the enterprise. As a result, outsourcing has reached new forms of expression that can help the enterprises to gain competitive advantage. In the context of a grown market, a new concept appears, namely the multisourcing which it refers to the outsourcing model of the future [1] that businesses must prepare to accept and use. This concept or model of the future refers to working with several suppliers, which are competitors in a spirit of trust and teamwork, in a collaborative process to maximize the benefits associated with outsourcing process.Business Outsourcing, Audit, Economic and Financial Analysis, Information Technology Outsourcing

Principles of Information Visualization for Business Research

In the era of data-centric-science, a large number of visualization tools have been created to help researchers understand increasingly rich business databases. Information visualization is a process of constructing a visual presentation of business quantitative data, especially prepared for managerial use. Interactive information visualization provide researchers with remarkable tools for discovery and innovation. By combining powerful data mining methods with user-controlled interfaces, users are beginning to benefit from these potent telescopes for high-dimensional spaces. They can begin with an overview, zoom in on areas of interest, filter out unwanted items, and then click for details-on-demand. With careful design and efficient algorithms, the dynamic queries approach to data exploration can provide 100 msec updates even for million-record databases. Visualizations of business information are therefore widely used in actually business decision support systems, and by business researchers also. Visual user interfaces called dashboards are tools for reporting the status of a company and its business environment to facilitate business intelligence and performance management activities. In this study, we examine the research on concepts, and the principles of business information visualization, because we hope to be using correctly by business Ph.D. students in their researches. Visual representations are likely to improve business managers, and business researchers efficiency, offer new insights, and encouraging comparisons.business quantitative data, visual presentation, visual interfaces, performance management, business intelligence

The definitive version was published in Journal of the Acoustical Society of America 138 (2015); 3742, doi:10.1121/1.4937607.Analytical and numerical scatteringmodels with accompanying digital representations are used increasingly to predict acoustic backscatter by fish and zooplankton in research and ecosystem monitoring applications. Ten such models were applied to targets with simple geometric shapes and parameterized (e.g., size and material properties) to represent biological organisms such as zooplankton and fish, and their predictions of acoustic backscatter were compared to those from exact or approximate analytical models, i.e., benchmarks. These comparisons were made for a sphere, spherical shell, prolate spheroid, and finite cylinder, each with homogeneous composition. For each shape, four target boundary conditions were considered: rigid-fixed, pressure-release, gas-filled, and weakly scattering. Target strength (dB re 1 m2) was calculated as a function of insonifying frequency (f = 12 to 400 kHz) and angle of incidence (θ = 0° to 90°). In general, the numerical models (i.e., boundary- and finite-element) matched the benchmarks over the full range of simulation parameters. While inherent errors associated with the approximate analytical models were illustrated, so were the advantages as they are computationally efficient and in certain cases, outperformed the numerical models under conditions where the numerical models did not convergeThis work was supported by the NOAA Fisheries Advanced Sampling Technologies Working Group, the Office of Naval Research, and the National Oceanic Partnership Program.

The definitive version was published in Journal of the Acoustical Society of America 111 (2002): 1197-1210, doi:10.1121/1.1433813.Scattering models that correctly incorporate organism size and shape are a critical component for the remote detection and classification of many marine organisms. In this work, an acoustic scattering model has been developed for fluid-like zooplankton that is based on the distorted wave Born approximation (DWBA) and that makes use of high-resolution three-dimensional measurements of the animal's outer boundary shape. High-resolution computerized tomography (CT) was used to determine the three-dimensional digitizations of animal shape. This study focuses on developing the methodology for incorporating high-resolution CT scans into a scattering model that is generally valid for any body with fluid-like material properties. The model predictions are compared to controlled laboratory measurements of the acoustic backscattering from live individual decapod shrimp. The frequency range used was 50 kHz to 1 MHz and the angular characteristics of the backscattering were investigated with up to a 1° angular resolution. The practical conditions under which it is necessary to make use of high-resolution digitizations of shape are assessed.This work was supported in part by the Woods Hole Oceanographic Institution Education Office

A Normative Pragmatic Theory of Exhorting

The final publication is available at Springer via http://dx.doi.org/10.1007/s10503-018-9465-y.We submit a normative pragmatic theory of exhorting—an account of conceptually necessary and potentially efficacious components of a coherent strategy for securing a sympathetic hearing for efforts to urge and inspire addressees to act on high-minded principles. Based on a Gricean analysis of utterance-meaning, we argue that the concept of exhorting comprises making statements openly urging addressees to perform some high-minded, principled course of action; openly intending to inspire addressees to act on the principles; and intending that addressees’ recognition of the intentions to urge and inspire creates reasons for addressees to grant a sympathetic hearing to what the speaker has to say. We show that the theory accounts for the design of Abraham Lincoln’s Cooper Union address. By doing so we add to the inventory of reasons why social actors make arguments, continue a line of research showing the relationship of arguing to master speech acts, and show that making arguments can be an effective strategy for inspiring principled action
