Most relationships between variables describing natural and behavioral phenomena are nonlinear, with U-curve and S-curve relationships being particularly common. Yet, structural equation modeling software tools do not estimate coefficients of association taking nonlinear relationships between latent variables into consideration. This can lead to misleading results, particularly in multivariate and complex phenomena like those related to e-collaboration. One notable exception is WarpPLS (available from: warppls.com), a new structural equation modeling software currently available in its first release. The discussion presented in this paper contributes to the literature on e-collaboration research methods by providing a description of the main features of WarpPLS in the context of an e-collaboration study. The focus of this discussion is on the software’s features and their use and not on e-collaboration study itself. Particular emphasis is placed on the five steps through which a structural equation modeling analysis is conducted through WarpPLS.

Scientific Results

The paper describes the mathematical models, algorithms and software tools developed by the author for searching for objects in information analysis systems. A search query is a subject area, which is specified by keywords or rubrics of various classifiers. The search takes into account the relevance of the objects to the query, which is calculated by constructing thematic portraits of the objects and comparing them to the query, as well as the significance of the objects, the rules for calculating which can be set dynamically. Thematic portraits of objects are built by analyzing their relations with other objects in the system, for which a topic is specified. When applied to current research information systems, such an approach can be used to search for scientific results in a given subject area and for experts in this area.

Typical Sequence

This paper examines the security threats to guaranteed information systems, as well as measures to combat encryption viruses. A typical sequence of cyberattacks with information encryption using software tools to implement attacks is determined. The sequence of procedures of the WannaCry encryption part is described. The paper proposes a description of the computational complexity of encrypted data recovery problems, including methods for parallelizing the solution of cryptanalysis problems, methods used to solve problems of cryptosystem stability assessment, vulnerability search and decryption depending on basic mathematical methods. The application of distributed computing technology to solve problems of recovery of encrypted resources is described. The paper states that in modern conditions of constant development of cryptography methods with a high level of stability and their wide availability a necessary condition for improving the recovery of encrypted programs - data seekers is to create a special software security monitor and build specialized multiprocessor systems to implement cryptanalysis methods with wide access of authorized users. , from the point of view of minimizing the ratio "cost - the result" the most rational approach to creating specialized multiprocessor systems is to build a cluster system based on the most powerful general-purpose computers using hardware computing accelerators based on programmable logic integrated circuits to increase the effectiveness of attacks on cryptographic software tools for the implementation of attacks, it is advisable to develop technologies for active actions in cyberspace, in particular, those that provide the formation of hidden channels.

ABSTRACT This paper discusses the collaboration our university has developed between the AIS and MIS programs. We include learning objectives for the overall learning objectives of our integrated program, suggestions for collaboration, and the courses addressing the identified objectives. The authors have found that using software tools can improve collaboration across departments can add to the learning experience in both the accounting and MIS programs. AIS instructors can use software tools to demonstrate how control requirements are implemented within information systems. MIS instructors can use software tools to provide explanations and examples of program structures and data structures used in information systems. Instructors with training in ERP systems can use software tools to add valuable perspective in discussions of scalability, multiple currencies, conversion of measuring units, and automation of business processes. Tools which are used to support instruction can also be used to enable collaboration between faculty members. When group projects are used to teach information system development, additional collaboration tools can be included to give students experience in working within a workgroup environment. The authors discuss their experience in the use of software packages and collaboration tools to better prepare our students to succeed in the challenging business environment of audit and IT professionals.
