Chapter VIII discusses the server operating systems’ main attributes from the selection perspective. Several selection criteria are explained through a model that contains 22 most important features of server operating systems in regard to business continuity perspective. Some empirical studies and results on the performances of most widely used server operating systems are provided.

Car Navigation

In a car navigation system the conventional information used to guide drivers in selecting their driving routes typically considers only one criterion, usually the Shortest Distance Path (SDP). However, drivers may apply multiple criteria to decide their driving routes. In this paper, possible route selection criteria together with a Multi Objective Path Optimisation (MOPO) model and algorithms for solving the MOPO problem are proposed. Three types of decision criteria were used to present the characteristics of the proposed model. They relate to the cumulative SDP, passed intersections (Least Node Path – LNP) and number of turns (Minimum Turn Path – MTP). A two-step technique which incorporates shortest path algorithms for solving the MOPO problem was tested. To demonstrate the advantage that the MOPO model provides drivers to assist in route selection, several empirical studies were conducted using two real road networks with different roadway types. With the aid of a Geographic Information System (GIS), drivers can easily and quickly obtain the optimal paths of the MOPO problem, despite the fact that these paths are highly complex and difficult to solve manually.

The Cost

Purpose The purpose of this paper is to present three heuristics for choosing supplier selection criteria. By considering the balance between the expected relative effort and benefit of using different selection criteria, the heuristics suggest which criteria should be prioritized. The heuristics serve to develop our understanding of the search and evaluation heuristics used in supplier selection and to facilitate further research. Design/methodology/approach The research is primarily theoretical, yet draws on empirical studies of supplier selection. The theoretical basis is Simon’s notion of procedural rationality (Simon, 1976). The author makes the general notion of procedural rationality more concrete for supplier selection by formally describing three heuristics for choosing selection criteria. The heuristics share the same logic but differ in terms of the precision of the input information required from the purchaser. The paper provides illustrations of the heuristics. Findings It appears that procedural rationality can be specified for the process of designing the supplier selection process by explicitly recognizing the cost and value of selection criteria. There is no one way of doing this, but at the most basic level, it requires an ordinal ranking of criteria. Already such a rudimentary, qualitative, assessment can help identifying suitable criteria. The heuristics developed appear compatible with established approaches for the subsequent selection of suppliers. Originality/value The paper addresses the early stage of supplier selection which has been largely ignored in the literature.

Chapter IX focuses on the role of system administration as an IT-profession and system administrator as a person who does the administrative (managerial) activites on servers and server operating systems. If server goes down for any reason or server operating system crashes, in most cases it is up to this person to “recover” the server from the bad situation and make sure that business – critical applications continue to run and provide services to end users. HP-UX as a server operating system platform is selected in order to demonstrate most commonly used techniques and features that may lead to higher levels of system availability.

Unexpected Outcome

It seems logical to assume that GAAP aimed at informing investors show a higher association with share prices (value relevance) than GAAP aimed at protecting creditors. The majority of empirical studies support this assumption. This paper examines the value relevance of IFRS and German GAAP. Regression analyses are applied to companies listed on the Frankfurt Stock Exchange and publishing exclusively either IFRS or German GAAP consolidated financial reports over the period 2000-2004. As a result of Regulation (EC) No 1606/2002, comparative research becomes impossible after 2004: German GAAP will no longer exist on European stock exchanges. The paper’s study is restricted to a single capital market in order to eliminate pricing differences between capital markets based in different countries that have already been done in earlier research. Improved circumstances for investigating value relevance compared with earlier research are, however, the selection criteria for the listed companies (emphasis on international transparency requirements, free float and free float market capitalisation) and the share prices used (average price around the end of the business year when the financial reporting data is not yet published). The results of the study show that German GAAP is statistically more value relevant than IFRS. These results have to be interpreted in the light of the selection criteria. It is an unexpected outcome calling for further research.

Server operating systems described in Chapter VI usually come preinstalled. Additional components can be installed “on-demand” in the form of ServerWare components and modules, as explained in previous chapter. However, there exist more advanced technologies, both hardware and software, aimed at further enhancing the levels of continuous computing and business continuity. These technologies are introduced and briefly explained in this chapter.

Server configurations described in Chapter V are operated by server operating systems. Server-based application software and business-critical applications are installed on these platforms. Taken together, they form what is called “server operating environment,” the hardware-operating system platform responsible for running business applications and keeping “business in business.” Chapter VI explains in more details server operating systems and their role in ensuring continuous computing and hence business continuity.

The problem of learning the kernel function has received considerable attention in machine learning. Much of the work has focused on kernel selection criteria, particularly on minimizing a regularized error functional over a prescribed set of kernels. Empirical studies indicate that this approach can enhance statistical performance and is computationally feasible. In this paper, we present a theoretical analysis of its generalization error. We establish for a wide variety of classes of kernels, such as the set of all multivariate Gaussian kernels, that this learning method generalizes well and, when the regularization parameter is appropriately chosen, it is consistent. A central role in our analysis is played by the interaction between the sample error and the approximation error.

A Current

Administrators of programs for children with communicative disorders in 11 midwestern states were surveyed to assess trends in the training and utilization of paraprofessionals. Topics included: (a) current trends in employment, (b) paraprofessional training, (c) use of ASHA and state guidelines, and (d) district policies for supervision. Selection criteria, use of job descriptions, training programs, and supervision practices and policies were examined. Results indicate that paraprofessionals are used but that standards for training and supervision are not consistently applied across all programs. Program administrators report minimal training for supervising professionals.
