    Nowadays, internal business processes are one of the crucial factors of firms’ competitive advantage achievement, which is becoming increasingly important, not only on local but also on global markets. Firms’ performance improvement depends to a large extent on its flexibility, adjustability and especially ability to manage internal business processes. Hence, use of information technology is among the fundamental elements of business process change, which not only improve competitiveness but also assure long term development and growth of the firm. For all these reasons, the main purpose of this article is firstly to establish that use of information technology is feasible in all industries, explain what possible obstacles for successful informatisation are, and which are major advantages after its implementation. Secondly, within theoretical aspect we present broaden view of informatisation in logistics, whilst practical example illustrates successful informatisation of transport process with adoption of GPS (Global Positioning System) in a transport firm. Furthermore, in this article we are also introducing a case study of three transport firms describing process flow before and after implementation identifying enhanced information quality, service quality and communication as a foremost advantages and achievements after informatisatio

    Methods of Paradox

    Despite growing scholarly interest in paradoxes, few studies have expressly engaged with the methodological mechanics of ‘doing’ paradox research. First, there are no clearly established guidelines regarding what should count as paradox in research endeavors. Second, there is uncertainty around who sees/thinks/experiences the paradox and what is relevant when it comes to the emergence, choice, interpretation and appropriation of paradoxes in empirical settings. Third, there is still confusion around where one can find evidence of paradoxes. This book chapter aims to shed some light on these methodological shortcomings. We suggest that paradox researchers can deal with these methodological challenges by 1) showing evidence of contradictory, interrelated, simultaneous and persistent paradoxical tensions in the empirical setting, 2) developing reliable and flexible protocols for paradox identification, 3) pushing for multi-level paradox studies, 4) practicing reflexivity, 5) staying close to the context, and 6) leveraging multi-modality

    Ermakov's Superintegrable Toy and Nonlocal Symmetries

    We investigate the symmetry properties of a pair of Ermakov equations. The system is superintegrable and yet possesses only three Lie point symmetries with the algebra sl(2,R). The number of point symmetries is insufficient and the algebra unsuitable for the complete specification of the system. We use the method of reduction of order to reduce the nonlinear fourth-order system to a third-order system comprising a linear second-order equation and a conservation law. We obtain the representation of the complete symmetry group from this system. Four of the required symmetries are nonlocal and the algebra is the direct sum of a one-dimensional Abelian algebra with the semidirect sum of a two-dimensional solvable algebra with a two-dimensional Abelian algebra. The problem illustrates the difficulties which can arise in very elementary systems. Our treatment demonstrates the existence of possible routes to overcome these problems in a systematic fashion.Comment: Published in SIGMA (Symmetry, Integrability and Geometry: Methods and Applications) at http://www.emis.de/journals/SIGMA

    Analytic Behaviour of Competition among Three Species

    Full text link
    We analyse the classical model of competition between three species studied by May and Leonard ({\it SIAM J Appl Math} \textbf{29} (1975) 243-256) with the approaches of singularity analysis and symmetry analysis to identify values of the parameters for which the system is integrable. We observe some striking relations between critical values arising from the approach of dynamical systems and the singularity and symmetry analyses.Comment: 14 pages, to appear in Journal of Nonlinear Mathematical Physic

    Individualism and Community for Voluntary Simplifiers

    Get PDF
    Voluntary simplicity is a cultural movement constructed around overt expressions of individualism in response to the excesses of ‘consumer society’. As the term also suggests, its general public recognition as a critical force against over-consumption appeals to a ‘moral good’. This has turned voluntary simplicity into a socially reflective movement which often appeals to ‘community’ and the social norms of collective action. This thesis explores historical developments in the theories of individualism and communitarianism which have influenced understandings of what constitutes a ‘voluntary simplifier’. The author contends that Ronald Inglehart’s (1977) theory of ‘postmaterialism’, the seminal theory underpinning voluntary simplicity, was quickly transformed into a concept which connoted various individual and social ‘goods’. This became a source of criticism for communitarian critics of consumerism, who associated this development with self-interest, further moral decline and a growing “culture of narcissism”. This is at odds with more recent theorists who view individualism in more pragmatic ways. Paul Lichterman’s (1996) notion of a “culture of personalism” and Clive Hamilton’s (2008) appeal to a kind of philosophical individualism have proven to be more compelling to both voluntary simplifiers and ‘self-help’ authors. This has not been a universally positive development, however. An examination of the “Simple Living Forums” within the thesis reveals a strong sense of modesty and commitment to pluralism amongst voluntary simplifiers, which reflects both an affirmation and a denial of self. Voluntary simplicity continues to lack adequate framing processes which are essential for maintaining a social movement. The thesis therefore concludes that voluntary simplicity is, ironically, associated with the excesses of consumer society and alienation from democratic processes. Because elements of consumer society have become part of the processes of late-capitalism, voluntary simplicity remains trapped between its critical centre and a culture of self-interest and insignificance
