Relative amenability

We introduce a relative fixed point property for subgroups of a locally compact group, which we call relative amenability. It is a priori weaker than amenability. We establish equivalent conditions, related among others to a problem studied by Reiter in 1968. We record a solution to Reiter's problem. We study the class X of groups in which relative amenability is equivalent to amenability for all closed subgroups; we prove that X contains all familiar groups. Actually, no group is known to lie outside X. Since relative amenability is closed under Chabauty limits, it follows that any Chabauty limit of amenable subgroups remains amenable if the ambient group belongs to the vast class X.Comment: We added a solution to Reiter's problem and a discussion of L^1-equivarianc

from e-Heritage systems to Interpretive Archaeology Systems.

The principal purpose of this paper is to examine which research approaches are best suited for determining the requirements of the next generation of interactive interpretation support systems for cultural heritage site. We are optimistic that such systems if properly designed to exploit the potential of advanced information and communication technologies (ICTs), can not only meet, but even exceed visitor-user expectations. The research framework proposed to achieve this ideal integrates insights from both Interpretive Archaeology and interpretive IS research. We call the application of ICT’s in systems for communicating cultural heritage information “e-Heritage Systems or e-HS. We define “Interpretive Archaeology Systems”(IAS) as a subclass of e-HS, the design of which is informed by hermeneutics and phenomenology, Therefore, the principal purpose of the paper is to promote a shift from e-HS to IAS. To illustrate the fruitfulness of our preferred approach for IAS requirements identification, we derive a set of criteria from our research philosophy and apply them to the evaluation of an existing e-HS: the ARCHEOGUIDE in Olympia.Information systems; Cultural heritage; Phenomenology; Interpretive Information Systems Research; Interpretive Archaeology; Hermeneutics; Interpretive Archaeology Systems;

Tools and techniques for AIS Strategic Planning.

AIS went through and will continue to undergo evolution and revolution as it grows. This article analyzes the current state of AIS and concludes it is in or approaching a crisis of priorities. Planning is the recommended path for solving this crisis. Four planning methods are proposed: stakeholder analysis, service matrix analysis, missions matrix analysis, and a four-year budget cycle.AIS, planning, planning methods, priority setting, stakeholder analysis, service matrix analysis, missions matrix analysis, budget cycleAssociation of Information Systems Planning; Planning method; Stakeholder analysis; Service matrix analysis; Missions matrix analysis; Planification stratégique;

An indiscrete Bieberbach theorem: from amenable CAT(0) groups to Tits buildings

Non-positively curved spaces admitting a cocompact isometric action of an amenable group are investigated. A classification is established under the assumption that there is no global fixed point at infinity under the full isometry group. The visual boundary is then a spherical building. When the ambient space is geodesically complete, it must be a product of flats, symmetric spaces, biregular trees and Bruhat--Tits buildings. We provide moreover a sufficient condition for a spherical building arising as the visual boundary of a proper CAT(0) space to be Moufang, and deduce that an irreducible locally finite Euclidean building of dimension at least 2 is a Bruhat--Tits building if and only if its automorphism group acts cocompactly and chamber-transitively at infinity.Comment: minor typos corrected; reference adde

BPM OR CPM？A CASE STUDY OF CROSS-DEPARTMENT COMMUNICATION BUSINESS OPERATION AND HIDDEN COST RELATED TO AMBIDEXTERITY PERFORMANCE

Business process management (BPM) as a mature business operation management method has been applied by many enterprises. Its main concerns focus on solving the cross departmental communication problems. Cross-department communication is a visible symptom of the growing business problems of companies related to complexity，it is also a problem strongly related to BPM. These barriers will lead to low efficiency and poor-quality work, which is common in most organizations in China. This will bring hidden costs to the organization and even impact long-term performance. In the digital transformation age, organization ambidexterity is more important than ever to obtain short-term and long-term benefits. This case study suggests to combine the ambidextrous and hidden costs theory for outlining a collaborative network communication model (CNCM) and theory relationship model of hidden costs and ambidexterity BPM, in order to inves-tigate the effect between the cross-department communication operation structure and organiza-tional performance. This case study provided data collection by three data sources: 40 interviews of managers and employees, company records，observations over 3 months. The findings of the field study of this case are that cross-department communication operation structure has an effect on organizational performance and digital innovation. It also suggests that CNCM positively influences organizational exploration and exploitation ability. It can also alleviate cross-department communication obstacles, low efficiency, and poor-quality work

INFORMATION SYSTEM STRATEGY PLANNING RELAT-ED TO SEAM: A CASE STUDY OF EA AND DIGITAL TRANSFORMATION COMBINATION

Inconsistency always occurs between digital transformation (DT) strategy and information system（IS）and enterprise architecture (EA) planning. This symptom leads to repeated investment, de-lay, or failure in DT projects. In addition, it will create leakages in DT value. Moreover, in the dy-namic digital environment, the inconsistency of between DT strategy and EA planning process is exacerbated due to dynamic business strategies. This paper applies SEAM and BPM theories to explore the scenario method for applying EA to DT strategies operation to explain inconsistent strategic planning symptoms and outline the DT-EA strategy planning integration process frame-work. The research method of this paper is multiple case studies, and the data collection sources include semi-structured interviews of 106 interviewees, material collection, literature comparison, and observation. By comparing four critical cases, this research shows the relationship between DT and EA and reveals the dysfunction in DT strategic implementation from the SEAM and BPM perspective. In practice, this research integrates DT and EA to provide a context method for enter-prise DT strategy planning design
