Governance of the London 2012 Olympic Games legacy
No full text© The Author(s) 2011. This is the author's accepted manuscript. The final published article is available from the link below.This study addresses the governance of the London 2012 Olympics legacy. It presents legacy not as a retrospective but a prospective concept concerned with shaping the future through interactions between the state, market and society. This entails designing systems of governance to guide and steer collective actions towards a consensus amongst various parties concerned. Four modes of governance and a range of policy instruments were examined in the delivery of sustainable London Olympics sport legacy including coercive, voluntarism, targeting and framework regulation. The British government actively created a new policy space and promoted institutional conduct consistent with its legacy visions. The current global legacy framework is lacking the governance dimension and its logic needs to be reconsidered. A meaningful sport legacy requires not top-down approaches but locally informed strategies supported by a developmental design of the Olympic Games informed by sustainable principles
A Productive Response to Legacy Systems
No full textRequirements change. The requirements of a legacy information system change, often
in unanticipated ways, and at a more rapid pace than the rate at which the information
system itself can be evolved to support them. The capabilities of a legacy system
progressively fall further and further behind their evolving requirements, in a degrading
process termed petrification. As systems petrify, they deliver diminishing business
value, hamper business effectiveness, and drain organisational resources.
To address legacy systems, the first challenge is to understand how to shed their
resistance to tracking requirements change. The second challenge is to ensure that a
newly adaptable system never again petrifies into a change resistant legacy system. This
thesis addresses both challenges.
The approach outlined herein is underpinned by an agile migration process - termed
Productive Migration - that homes in upon the specific causes of petrification within
each particular legacy system and provides guidance upon how to address them. That
guidance comes in part from a personalised catalogue of petrifying patterns, which
capture recurring themes underlying petrification. These steer us to the problems
actually present in a given legacy system, and lead us to suitable antidote productive
patterns via which we can deal with those problems one by one.
To prevent newly adaptable systems from again degrading into legacy systems, we
appeal to a follow-on process, termed Productive Evolution, which embraces and keeps
pace with change rather than resisting and falling behind it. Productive Evolution
teaches us to be vigilant against signs of system petrification and helps us to nip them in
the bud. The aim is to nurture systems that remain supportive of the business, that are
adaptable in step with ongoing requirements change, and that continue to retain their
value as significant business assets
LAG: Achieving transparent access to legacy data by leveraging grid environment
No full textThe world today is experiencing an explosive growth of data generated by
information digitization. Due to the unprecedented advance in software and
hardware, large amounts of data gradually becomes legacy data and inaccessible.
This is building a digital black hole, and it is becoming a big challenge to
access, process, and preserve the legacy data. Grid provides flexible, secure,
and coordinated resource sharing among dynamic collections of individuals,
institutions, and resources. It allows users and applications to access the
aggregated resources in a transparent manner. This paper proposes a Legacy
Application Grid (LAG) architecture. This architecture deploys diverse legacy
applications in a grid environment and provides a transparent access to the
remote LAG users who want to access the legacy data. In contrast to the existing
methods which attempt to tackle legacy data and legacy applications, we wrap a
display protocol into grid services. The service provider, who wants to deploy
any legacy applications, just needs to deploy the protocol based grid service,
describe and pass the parameters of those legacy applications to the service.
Compared with the traditional approaches, the method proposed in this paper is
very cost-effective because it avoids converting legacy data from one format to
another format or upgrading legacy applications one by one. An implemented
prototype validates that the LAG architecture trades acceptable performance
degradation for a transparent and remote access to legacy data. (C) 2010

Re-thinking the Legacy 2012: The Olympics as commodity and gift
No full textThis paper opens discussion about the nature of Olympic ‘legacy’ and articulates a contradiction in the way ‘legacy’ is conceived - between ’gift’ and ’commodity’ (Mauss 1954).The The paper argues that establishing working definitions and parameters for ‘legacy’ is a difficult task. Defining ‘legacy’ is problematic especially if conceived as an entirely predictable or measurable set of objectives. Indeed, the definition of ‘legacy’ is partly constitutive of the legacy itself, a component of achievements that the city might make. Such a ‘legacy definition’ will become a functional term in the complex planning and evolving conceptions underpinning urban change for some time—if successfully negotiated and if governable. As such, ‘legacy’, and the activities and values entailed to it, can come to provide a catalytic ‘vocabulary of motives’ and a legitimating discourse enabling politicians, communities and their individual representatives to justify investments, evolving strategies and activities connected to and connecting developmental gains in a more or less healthy fashion. It is because of this that legacy and its various meanings come to matter
Introduction: preliminary reflections on the legacy of Pierre Bourdieu
No full textBook synopsis: Pierre Bourdieu is widely regarded as one of the most influential sociologists of his generation, and yet the reception of his work in different cultural contexts and academic disciplines has been varied and uneven. This volume maps out the legacy of Pierre Bourdieu in contemporary social and political thought from the standpoint of classical European sociology and from the broader perspective of transatlantic social science. It brings together contributions from prominent scholars in the field, providing a range of perspectives on the continuing relevance of Bourdieu’s oeuvre to substantive problems in social and political analysis
An ontological approach for recovering legacy business content
No full textLegacy Information Systems (LIS) pose a challenge for many organizations. On one hand, LIS are viewed as aging systems needing replacement; on the other hand, years of accumulated business knowledge have made these systems mission-critical. Current approaches however are often criticized for being overtly dependent on technology and ignoring the business knowledge which resides within LIS. In this light, this paper proposes a means of capturing the business knowledge in a technology agnostic manner and transforming it in a way that reaps the benefits of clear semantic expression - this transformation is achieved via the careful use of ontology. The approach called Content Sophistication (CS) aims to provide a model of the business that more closely adheres to the semantics and relationships of objects existing in the real world. The approach is illustrated via an example taken from a case study concerning the renovation of a large financial system and the outcome of the approach results in technology agnostic models that show improvements along several dimensions
Legacy System Anti-Patterns and a Pattern-Oriented Migration Response
No full textMature information systems grow old disgracefully as successive waves of hacking result in accidental architectures which resist the reflection of on-going business process change. Such petrified systems are termed legacy systems. Legacy systems are simultaneously business assets and business liabilities. Their hard-won dependability and accurate reflection of tacit business knowledge prevents us from undertaking green-field development of replacement systems. Their resistance to the reflection of business process change prevents us from retaining them. Consequently, we are drawn in this paper to a controlled pattern-oriented legacy system migration strategy. Legacy systems exhibit six undesirable anti-patterns. A legacy system migration strategy must focus upon the controlled elimination of these anti-patterns by the step-wise application of six corresponding desirable patterns. Adherence to this migration strategy results in adaptive systems reflecting purposeful architectures open to the on-going reflection of business process change. Without such a strategy there is a very real danger that legacy system migration will occur all too literally. That is, the old legacy system will be migrated to a new legacy system albeit it one using the latest buzzword-compliant technology

Legacy Scholars II: The 2021 Nominations
No full textThe concept of “Legacy Scholars” as a special issue series was originally developed by the International Journal of Gender and Entrepreneurship (IJGE) at one of our editorial meetings in London. Led by IJGE Consulting Editor Dr Kate Lewis, the series was launched in 2020 with the special issue: Celebrating a Decade of Research in Gender and Entrepreneurship: The Legacy Special Issue. This vehicle was appropriate for our core objectives – platforming eminent research scholars in the field while also reaching out to the next generation of excellent scholars by way of building a legacy of research scholarship. Hence, for our first legacy special issue, we invited established eminent gender and entrepreneurship scholars to submit papers that reflected on the developments within the field through their personal lens and then to nominate young talented scholars whose work would be platformed in a subsequent legacy special issue. The 2020 eminent scholars (Vol. 12, Issue 1) included Professors Brush, Greene, Welter, Marlow, Hughes, Jennings, Watson, Holmquist, Sundin and Nelson. We are extremely grateful to these leading lights for not only sharing their research insights with the IJGE community by allowing us to publish their scholarly contributions but also for taking the time to pass the baton to the next generation by offering their personal nominations for the subsequent legacy special issue; it is the work of these young scholars that we platform here. Consistent with our original intention to build a legacy of gender and entrepreneurship scholarship, we will be reaching out to the 2021 scholars to offer their nominations for the legacy special issue III.No Full Tex
EventPorts: Preventing Legacy Componentware
No full textIn our work with legacy information systems we have found two prevalent anti-patterns - tight coupling and code pollution - which, if not addressed in replacement systems, could result in today's new systems simply becoming tomorrow's new legacy system. Tight coupling results from Explicit Invocation across collaborating components. Code pollution results from implicit (rather than explicit) reflection of time-ordered collaboration protocols. These anti-patterns diminish component maintainability, flexibility, and reusability. In response, we propose a synthesis of Implicit Invocation (which reduces tight coupling) and Statecharts (which reflect collaboration protocols directly). This paper describes the development of EventPorts, which realize this synthesis and thus encapsulate a novel and promising component collaboration technology
