Accumulative information enhancement in the self-organizing maps and its application to the analysis of mission statements

Kitajima R., Kamimura R.

This paper proposes a new information-theoretic method based on the information enhancement method to extract important input variables. The information enhancement method was developed to detect important components in neural systems. Previous methods have focused on the detection of only the most important components, and therefore have failed to fully incorporated the information contained in the components into learning processes. In addition, it has been observed that the information enhancement method cannot always extract input information from input patterns. Thus, in this paper a computational method is developed to accumulate information content in the process of information enhancement. The method was applied to an artificial data set and the analysis of mission statements. The results demonstrate that while we were able to explicitly extract the symmetric properties of the data from the artificial data set, only one main factor was able to be extracted from the mission statement, namely, “contribution to the society”. The companies with higher profits tend to have mission statements concerning the society. The results can be considered to be a first step toward the full clarification of the importance of mission statements in actual business activities.

Recent research has shown that work stress has become a widespread concern in Australia and other countries. It is a growing concern across all employment sectors as well as occupational levels and reported as a common cause of occupational illness. Work stress can be prevented if it is identified, measured and changes are made to the work environment. Multi-Agent technology has been used in many applications but has not been applied in psychology for analysing data. This paper presents hybridized techniques, which have been used to develop an online tool for work stress assessment and prevention.

Ostatnie badania wykazały, że stres w miejscu pracy stał się przedmiotem rosnących obaw w Australii i w innych krajach. Wszystkie sektory zatrudnienia doświadczają wzrostu psychicznych chorób zatrudnieniowych. Stres w miejscu pracy może być uniknięty jeśli jest identyfikowany, mierzony i stosowne zmiany są implementowane w środowisku pracy. Technologia systemów wieloagentowych jest używana w wielu aplikacjach, lecz nie była dotąd zastosowana w psychologii do analizy danych. Artykuł prezentuje techniki hybrydowe, zastosowane do oceny online i prewencji stresu.
