As part of an examination of the problems of instrumentation compatible with on-line computers, a design has been produced for a simple quasi-digital sensor system. In this, the information about the sensed variable is carried by the number of pulses in a pulse train transmitted by the sensor upon interrogation. This form of sensor system has a number of attractive features. The characteristics of the system are analysed and possibilities of further development proposed.

Above-threshold dissociation (ATD) process of the molecular ions HD+ steered by a femtosecond laser pulse train (LPT) is investigated theoretically using the time-dependent quantum wave packet method. Energy-dependent distributions of ATD fragments are analyzed by using an asymptotic-flow expression in the momentum space. It is found that fragment kinetic energy spectra shift to low energy region with increasing pulse number of LPT. The photofragment branching ratio between the 1sσg and 2pσu dissociation channels is sensitive to the pulse number of LPT. The momentum distribution of the ATD fragments is discussed in detail.

A critical component of the learning process lies in the feedback that students receive on their work that validates their progress, identifies flaws in their thinking, and identifies skills that still need to be learned. Many higher-education institutions have developed an active pedagogy that gives students opportunities for different forms of assessment and feedback. This means that students have numerous lab exercises, assignments, and projects. Both instructors and students thus require effective tools to efficiently manage the submission, assessment, and individualized feedback of students’ work. The open-source web application MarkUs aims at meeting these needs: it facilitates the submission and assessment of students’ work. Students directly submit their work using MarkUs, rather than printing it, or sending it by email. The instructors or teaching assistants use MarkUs’s interface to view the students’ work, annotate it, and fill in a marking rubric. Students use the same interface to read the annotations and learn from the assessment. Managing the students’ submissions and the instructors assessments within a single online system, has led to several positive pedagogical outcomes: the number of late submissions has decreased, the assessment time has been drastically reduced, students can access their results and read the instructor’s feedback immediately after the grading process is completed. Using MarkUs has also significantly reduced the time that instructors spend collecting assignments, creating the marking schemes, passing them on to graders, handling special cases, and returning work to the students. In this paper, we introduce MarkUs’ features, and illustrate their benefits for higher education through our own teaching experiences and that of our colleagues. We also describe an important benefit of the fact that the tool itself is open-source. MarkUs has been developed entirely by students giving them a valuable learning opportunity as they work on a large software system that real users depend on. Virtuous circles indeed arise, with former users of MarkUs becoming developers and then supervisors of further development. We will conclude by drawing perspectives about forthcoming features and use, both technically and pedagogically.

The article aims to assess the benefits of implementing the corporate social responsibility (CRS) concept in enterprises and attempts to examine its impact on society and the environment. The analysis of the effectiveness of investments related to CSR was carried out based on literature review and own research (on-line survey) on the example of L’Oréal Polska. The conclusions from the research confirm the existence of numerous profits related to the implementation of CSR initiatives undertaken by the company. Considering own actions in a forward-looking way and taking responsibility for them shows that CSR is a bridge between the present and the future of business. Therefore, the further development of this concept can be forecasted.

Principles Of Good Practice

Summary Objective: The National Cancer Institute Thesaurus is described by its authors as “a biomedical vocabulary that provides consistent, unambiguous codes and definitions for concepts used in cancer research” and which “exhibits ontology-like properties in its construction and use”. We performed a qualitative analysis of the Thesaurus in order to assess its conformity with principles of good practice in terminology and ontology design. Materials and Methods: We used both the on-line browsable version of the Thesaurus and its OWL-representation (version 04.08b, released on August 2, 2004), measuring each in light of the requirements put forward in relevant ISO terminology standards and in light of ontological principles advanced in the recent literature. Results: We found many mistakes and inconsistencies with respect to the term-formation principles used, the underlying knowledge representation system, and missing or inappropriately assigned verbal and formal definitions. Conclusion: Version 04.08b of the NCI Thesaurus suffers from the same broad range of problems that have been observed in other biomedical terminologies. For its further development, we recommend the use of a more principled approach that allows the Thesaurus to be tested not just for internal consistency but also for its degree of correspondence to that part of reality which it is designed to represent.

On-line system was developed to gauge film thickness using isotope, by which the problem of difficulty in measuring wide film thickness was resolved. Two-point method, determining working curve of gauging system, was introduced, by which time spent on experiment could be decreased, and adaptability of working curve under different condition was improved. After analyzing measuring errors, emendation method for every error source was discussed .Method taking count of pulse number within a period of time was applied, by which measuring precision was improved, so this method can be used widely in other applications .This measuring system has obtained satisfying effect in measuring film thickness, and products can be bought in market .

Currently, the market is crowded with commercial enterprises, which makes it necessary to maintain the competitiveness of modern companies. One of the effective ways to support its functioning in the market and successful further development is the development and implementation of innovative projects. At the same time, when managing innovative projects, developers face various risks that should be minimized in a timely manner. Risk reduction is a rather complex process, as there is a high level of uncertainty inherent in innovative projects. Therefore, in order to minimize the risks of innovative projects, it is important to choose the best quality methods and tools that will form an effective risk reduction mechanism as a result. This article presents the concepts of innovation project, risk management and risk reduction mechanism. Methods and tools for reducing the risks of innovative projects are considered, the main types of risk minimization mechanisms are identified. In addition, the author conducted an analysis of innovative projects of the Russian retail chains "Magnit" and "X5 Retail Group", identified the main mechanisms for reducing the risks of innovative projects and programs used in these retail chains.
