This article concerns a class of groups of Fibonacci type introduced by Johnson and Mawdesley that includes Conway's Fibonacci groups, the Sieradski groups, and the Gilbert–Howie groups. This class of groups provides an interesting focus for developing the theory of cyclically presented groups and, following questions by Bardakov and Vesnin and by Cavicchioli, Hegenbarth, and Repovš, they have enjoyed renewed interest in recent years. We survey results concerning their algebraic properties, such as isomorphisms within the class, the classification of the finite groups, small cancellation properties, abelianizations, asphericity, connections with Labeled Oriented Graph groups, and the semigroups of Fibonacci type. Further, we present a new method of proving the classification of the finite groups that deals with all but three groups.

The modern enterprises consider the sustainable development as the one of basic conceptions of one’s activity. In recent years, an increasing number of private as well as public organizations have been engaged with implementation and using of environmental management systems (EMSs). The research is built up by two main parts. In the first, author prepared theoretical analyses of literature and scientific publications. The second part based on survey results collected from Latvian companies using in depth interviews. Author proposes that the process of environmentally oriented business should be studied as a multi-dimensional issue. Company’s external and internal environment elements were shown. In article author also investigated different factors influencing company’s environmental management and motives of implementing EMS.

The complexity of the control conditions for channel processes is examined by the case of the Severnaya Dvina River and its main tributary the Vychegda River, which are both the most important waterways of the European North of Russia. The developed and approved earlier methodology was applied to rank rivers in by the channel stability, the load and composition of sediments (the factor was applied for the first time to the rivers under study), water capacity, geological and geomorphological conditions of the channel formation conditions (embedded riverbeds or channels with wide floodplain), evolution of different morpho/dynamic types of channel, abundance and mode of deformations of riffles. The latter factor controls both possibility and features of regulative works when designing activities in water economics, navigation and construction. The data on the sediment amounts dredged from riverbeds to ensure the waterway functioning are demonstrated to be the integral estimation of the control conditions for channel processes.

Purpose Enterprise social media (ESM) platforms are rapidly diffusing in the business context because they can bring substantial benefits to companies by enhancing their knowledge management (KM) processes. However, such benefits materialize only if active employee participation is ensured. Therefore, it is crucial to understand how individual employees use an ESM platform to assist their knowledge-related activities. This paper contributes to this topic by proposing a classification of ESM users based on two dimensions: frequency and type (active or passive) of use. Design/methodology/approach The paper presents the results of a survey of 262 employees of an international engineering service company that has adopted an ESM platform to support its KM processes. Statistical methods (e.g. ANOVA, Tukey’s b) were applied to verify the usefulness of the proposed typology and identify the main aspects that characterize the different user groups. Findings The survey results confirm the existence of different types of ESM users and provide the empirical basis for developing a bi-dimensional classification from which four user groups were derived and characterized: frequent contributors, sporadic contributors, frequent lurkers and sporadic lurkers. Research limitations/implications The main limitation is that only one company in one sector with specific knowledge needs and capabilities was investigated. Practical implications The study provides useful suggestions for how to promote the use of an ESM and particularly for how to encourage less frequent and less active users to increase their participation in a platform. Originality/value The paper contributes to a better understanding of how employees approach ESM by identifying factors that characterize different user groups.

Abstract: Lampu Satu settlement is one of 12 slum areas in Merauke Regency. Based on the verification results, Lampu Satu slum settlement is the largest, which is 43.67 hectares or 39.44% of the total area of Merauke Regency slum areas. The purpose of this study is to determine the classification and concept of treatment slum settlements in the Merauke One Light settlement. The analytical method used is descriptive quantitative analysis of the characteristics of the Merauke Lampu Satu slums and measurement of the survey results based on the Minister of Public Works and Housing No. 2 of 2016 to determine the classification of slums and to analyze the concept of handling. The final results obtained in this study are the classification of Lampu Satu slums at a moderate level of slums. The concept of treatment that can be done is prevention with the socialization of licensing procedures, healthy living behaviors, waste management, fire disasters, as well as socialization of regional spatial plans. While the improvement of the quality of settlements is carried out on infrastructure and facilities that are still not by applicable standards and criteria as well as by conducting a resettlement program in settlements located in coastal zones.Keyword: classification; slums; concept of treatmentAbstrak: Permukiman Lampu Satu merupakan salah satu dari 12 lokasi kawasan permukiman kumuh pada Kabupaten Merauke.

The morphodynamic classification of the Sukil river channel made it possible to determine the hydromorphological processes and to study the factors that determine them. The channel was classified according to the method of R.S. Chalov. Three main classification criteria were taken into account: the geomorphological type of conditions for the formation of the channel; the type of channel processes; the mophrodynamic type of channel. According to the geomorphological type of channel-forming conditions, the channel is divided into the incised channel – located mainly in mountainous and semi-mountainous parts with a characteristic the narrow valley, laid in sandstones, siltstones, and argillites; confined channel – located in intermountain basins, with one bank of channel composed of bedrock, and the other – of Quaternary sediments; wide-floodplain channel – mainly located in the lower part of the channel on the Stryi-Zhydachiv basin, laid in the Quaternary deposits of loams and sands. According to the type of channel processes, the channels with developed alluvial forms and without developed alluvial forms are dominant. Together they make up 2/3 of the channel. Other types of channels are wide-floodplain – characterized by slow flow and stable development of the meandering process, and rapid-waterfall – located in the upper reaches of the channel. The latter is characterized by a stormy current and the presence of numerous rapids made of boulders and wood. There are 3 main morphodynamic types of the channel – meandering, branched, and straightforward, and 6 their subtypes. Meandering, incised channels are characterized by structural meanders, their shores are composed of hard rocks, mostly sandstones. The meandering confined channels are defined by the root bank in the apical part and the upper wing along the root bank, which leads to the formation of segmental and blockage convolutions. Meandering, broad-flooded channels are characterized by longitudinal displacement of meanders, their convolutions are segmented, rarely loop-shaped. The coefficient of meandering gradually increases from the mountainous part of the channel to the plain one (1.10–1.35). Branched type is represented by a single complex and floodplain-channel subtypes. The size of the islands that divide the channel into arms is from a few meters to 350–400 m. The straightforward type of channel is widespread and is 1/3 of the total length of the river. Key words: channel type; straightforward; branched; meandering; incised; confined; floodplain.

This chapter is an attempt to explore the links between the types of innovation, the types of organizational change and levels of learning based on a study of 160 Chinese organizations. The authors provide the classification of innovation, organizational change and learning as the theoretical framework. On the basis of survey results, the authors find out there are close connections between the three aspects: innovation type, change type and learning type. There is a direct link between the types of innovation and learning in lower level. However, in the companies which experienced administrative innovation and ancillary innovation, the rate of occurrence of triple-loop learning is almost the same. Moreover, there is not necessarily corresponding relation between the types of innovation and change. Despite the fact that the highest level of innovation is accompanied by the deepest change, the lowest level of innovation may not be necessarily accompanied by the lower level change, i.e. the deepest scope of change may take place even if the lowest level of innovation happens in a Chinese organization.
