This paper is a reflective discussion on the use of equipment matrices to determine infrastructure requirements in an education context. This position was originally presented within the wider framework of a government-funded research project to initiate national policies for implementing IT within primary schools. Equipment matrices were seen by the policymakers funding this reasearch as an appropriate method for representing the needs of a school. Equipment matrices represent a systematised and regularised understanding of the relationships between social practices and technological tools (Curriculum Materials Information Services, 1997). The users of these tools are enmeshed within the matrix through a complex combination of meanings and interaction. However, the correlation of variables within a two-dimensional matrix produces a ‘simple’ representation of the available information that is heavily abbreviated. Lost among this condensation are the needs and presence of the user, either individually or collectively. The ‘snapshot’ of information that matrices present is, however, refined by the direct inclusion of volatile information such as contemporary equipment and sofware specifications. In this paper we argue that the range of factors beyond technical specifications that influence the use and understanding of information technology are necessary elements within any consideration of IT infrastructure requirements. These, however, can only be simultaneously included in the equipment matrix representation with more expansive incorporation of multiple parameters. Simplification, we advocate, should not be the aim of the methods that determine educational infrastructure requirements but rather, in its place, is the need for sensitivity to the learners and their needs.

The case centers on Shilling & Smith's acquisition of Xteria Inc. and the resulting need to quickly scale the company's IT infrastructure to accommodate the acquisition. The case is based on a real leasing problem faced by a major retail firm in the Chicago area when it purchased a small credit card processing firm and scaled the operations to handle the retail firm's credit card transactions. The CIO of Shilling & Smith needs to determine which lease option is the best means of providing the technical infrastructure needed to support the firm after the acquisition of Xteria. Several issues will drive this decision, including the value and useful life of the equipment, as well as the strategic context of the firm. This case examines how to evaluate different lease options when acquiring data center information technology infrastructure. Specifically, the case addresses software vs. hardware leasing, different lease terms, and choosing between different lease structures depending on the strategy and needs of a company. This case enables students to understand the different types of technology leases and in which situations these leases would be employed.The Shilling & Smith case examines how to evaluate different lease options when acquiring data center information technology infrastructure.

The South Australian Water case study illustrates the management challenges in aligning Information Technology with business objectives in a publicly owned corporation. To achieve the alignment, the new CIO begins by refreshing the IT infrastructure to support the required business applications. When the Government establishes ‘Improved water quality’ as a major corporate goal, the CIO seeks to add value to the business by developing a quality reporting system that leverages the existing technology. At the same time, he demonstrates to the corporation the IT function's capability to deliver business value through the management of multiple outsourcing vendors.

Abstract We show how to build a binary matrix from the MRHS representation of a symmetric-key cipher. The matrix contains the cipher represented as an equation system and can be used to assess a cipher’s resistance against algebraic attacks. We give an algorithm for solving the system and compute its complexity. The complexity is normally close to exhaustive search on the variables representing the user-selected key. Finally, we show that for some variants of LowMC, the joined MRHS matrix representation can be used to speed up regular encryption in addition to exhaustive key search.

SummaryBackground: Patient safety concerns every healthcare organization. Adoption of Health information technology (HIT) appears to have the potential to address this issue, however unanticipated and undesirable consequences from implementing HIT could lead to new and more complex hazards. This could be particularly problematic in developing countries, where regulations, policies and implementations are few, less standandarized and in some cases almost non-existing.Methods: Based on the available information and our own experience, we conducted a review of unintended consequences of HIT implementations, as they affect patient safety in developing countries.Results: We found that user dependency on the system, alert fatigue, less communications among healthcare actors and workarounds topics should be prioritize. Institution should consider existing knowledge, learn from other experiences and model their implementations to avoid known consequences. We also recommend that they monitor and communicate their own efforts to expand knowledge in the region.

Metadata Generation

The article deals with challenges and prospects of implementation of the Statistical Data and Metadata eXchange (SDMX) standard and using it in the international sharing of statistical data and metadata. The authors identified potential areas where this standard can be used, described a mechanism for data and metadata sharing according to SDMX standard. Major issues classified into three groups - general, statistical, information technology - were outlined by applying both domestic and foreign experience of implementation of the standard. These issues may arise at the national level (if the standard is implemented domestically), at the international level (when the standard is applied by international organizations), and at the national-international level (if the information is exchanged between national statistical data providers and international organizations). General issues arise at the regulatory level and are associated with establishing boundaries of responsibility of counterpart organizations at all three levels of interaction, as well as in terms of increasing the capacity to apply the SDMX standard. Issues of statistical nature are most often encountered due to the sharing of large amounts of data and metadata related to various thematic areas of statistics; there should be a unified structure of data and metadata generation and transmission. With the development of information sharing, arise challenges and issues associated with continuous monitoring and expanding SDMX code lists. At the same time, there is a lack of a universal data structure at the international level and, as a result, it is difficult to understand and apply at the national level the existing data structures developed by international organizations. Challenges of information technology are related to creating an IT infrastructure for data and metadata sharing using the SDMX standard. The IT infrastructure (depending on the participant status) includes the following elements: tools for the receiving organizations, tools for sending organization and the infrastructure for the IT professionals. For each of the outlined issues, the authors formulated some practical recommendations based on the complexity principle as applied to the implementation of the international SDMX standard for the exchange of data and metadata.

AbstractDuring a recent nematode survey in natural environments of the Los Alcornocales Regional Park narrow valleys, viz., the renowned 'canutos' excavated in the mountains that maintain a humid microclimate, in southern Spain, an amphimictic population of Xiphinema globosum was identified. Morphological and morphometric studies on this population fit the original and previous descriptions and represent the first report from Spain and southern Europe. Molecular characterisation of X. globosum from Spain using D2-D3 expansion regions of 28S rRNA, 18S rRNA and ITS1-rRNA is provided and maximum likelihood and Bayesian inference analysis were used to reconstruct phylogenetic relationships within X. globosum and other Xiphinema species. A supertree solution of the different phylogenetic trees obtained in this study and in other published studies using rDNA genes are presented using the matrix representation parsimony method (MRP) and the most similar supertree method (MSSA). The results revealed a closer phylogenetic relationship of X. globosum with X. diversicaudatum, X. bakeri and with some sequences of unidentified Xiphinema spp. deposited in GenBank.

The purpose of the study was to determine the problem of control of a dynamic system of higher dimension. Relying on Leontev input-output balance, we formalized the dynamic system and synthesized its control. Within the research, we developed a mathematical model that combines different working objects that consume and release various resources. The value of the penalty for all nodes and objects is introduced into the matrix representation of the problem, taking into account various options for their interaction, i.e., the observation problem. A matrix representation of the planning task at each working object is formed. For the formed system, a control loop is created; the influencing parameters of the external environment are indicated. We calculated the system operational mode, taking into account the interaction of the nodes of objects with each other when the parameters of the external environment influence them. Findings of research show that in achieving a complex result, the system is inefficient without optimal planning and accounting for the matrix of penalties for the interaction of nodes and objects of the dynamic system with each other. In a specific example, for a dynamic system with a dimension of 4.8 million parameters, we estimated the control taking into account the penalty matrix, which made it possible to increase the inflow of additional resources from the outside by 2.4 times from 130 billion conv. units up to 310 conv. units in 5 years. Taking into account the maximum optimization of control in the nodes, an increase of 3.66 times in the inflow of additional resources was ensured --- from 200.46 to 726.62 billion rubles
