Is agile project management applicable to construction?

This paper briefly summarises the evolution of Agile Project Management (APM) and differentiates it from lean and agile production and ‘leagile’ construction. The significant benefits being realized through employment of APM within the information systems industry are stated. The characteristics of APM are explored, including: philosophy, organizational attitudes and practices, planning, execution and control and learning. Finally, APM is subjectively assessed as to its potential contribution to the pre-design, design and construction phases. In conclusion, it is assessed that APM offers considerable potential for application in predesign and design but that there are significant hurdles to its adoption in the actual construction phase. Should these be overcome, APM offers benefits well beyond any individual project

An assessment of the business impacts of the UK's Enterprise Capital Funds

Recent European studies present persistently critical views of the under performance of government backed venture capital (GVC) schemes when compared to their private sector counterparts. However, they assess the performance of outmoded funding models and fail to contextualise the economic development role of these schemes. This paper provides a contemporary assessment of the business impacts of the UK government’s flagship Enterprise Capital Funds (ECFs) VC scheme in addressing the sub-£2m equity finance gap facing young potential high growth businesses requiring investments. Supply and demand-side evidence is presented from interviews with ECF fund managers, alternative private VCs, industry experts and surveys of successful and unsuccessful scheme applicants. We find that, despite the limitations of mid-scheme evaluation, ECFs are addressing the UK equity gap and delivering business employment, revenue and innovation impacts. However, further progress is required in order to achieve optimal business exits and sustainable early stage private VC system impacts

What is the role of public feeder markets in developing technology-based small firms? An exploration of the motivations for listing on AIM since the GFC

In the aftermath of the 2007 global financial crisis (GFC) stock markets experienced sharp decline in listings and marked reduction in Initial Public Offerings (IPOs). This paper explores the factors determining UK technology based small firm (TBSF) listings on the UK Alternative Investment Market (AIM) and whether this market has a role to play in their future development. A case study approach is used to contrast the experiences of five recent AIM listed TBSFs with five TBSFs approaching private equity investment exit that are considering an IPO. The paper concludes that macro market conditions, rather than managerial resource base or AIM market structural factors were most influential in TBSF pecking order preferences to undertake IPOs. From a resource based management perspective lifelong entrepreneurs were more likely than serial entrepreneurs to favour an IPO exit, as it supported their aims to continue to manage and grow UK-based companies. Additionally, with a more buoyant and sustainable AIM market TBSF investors are more likely to choose IPOs. To conclude, AIM played an important role in listed UK TBSF development. A more buoyant AIM could ease the UK finance escalator’s flow, facilitating more rapid UK TBSF growth

CP Violation, an experimental perspective

I present a review of current and near-future experimental investigations of CP violation. In this review, I cover limits on particle electric dipole moments (EDMs) and CP violation studies in the K and B systems. The wealth of results from the new B factories provide impressive constraints on the CKM quark mixing matrix elements. Current and future measurements are focusing on processes dominated by loop diagrams, which probe physics at high mass scales in low-energy experiments.Comment: Invited plenary talk, DPF meeting, August 200

Lessons from government venture capital funds to enable transition to a low-carbon economy: the U.K. case

Early-stage small- and medium-sized enterprise (SME) cleantech innovation, if properly funded, can initiate disruptive low-carbon reduction impacts across a wide range of sectors to meet climate change net zero requirements. The role of venture capital (VC) finance in successfully commercializing new technologies remains contentious, particularly where socio-environmental returns may well be greater than the economic returns that are the exclusive captures of the investors. This article addresses a pertinent question facing government policymakers: how best to support VC to achieve climate change objectives? It focuses on the supply-side policy, design, and implementation of four U.K. government-backed venture capital funds (GVCFs) at various stages of their development. A systems framework and an absorptive capacity learning lens inform a grounded qualitative methodology, spanning a decade of over 100 in-depth interviews with policymakers, fund managers (private and public), alternative finance providers, and low-carbon finance market experts. A model is developed to assess GVCF learning evolution to address the nascent early-stage precommercialization cleantech venture investment market. This avoids the pitfalls of quantitatively analyzing the investment outcomes of these long-horizon investment funds prior to their completion by providing qualitative process findings that inform policy, practice, and theory in the evolving early-stage low-carbon GVCF

The future of early stage and growth finance in Northern Ireland, Report to the Department for Enterprise, Trade and Investment (DETI)

SQW Ltd (SQW), working alongside academics from Glasgow University and Middlesex University were appointed by the Department for Enterprise, Trade and Investment (DETI) in April 2014 to undertake research into early stage and growth finance in Northern Ireland. The purpose of the study was to provide guidance on the development of early stage and growth finance, focused particularly on angel investment and venture capital, and drawing on the experience of other ‘successful’ locations internationally. This Synthesis Report sets out the key findings and messages from the research, and the guidance – covering a set of principles, strategic recommendations, and specific actions – that should inform the development of early stage and growth finance going forward in Northern Ireland

The Emerging Anglo-American Model: Convergence in Industrial Relations Institutions?

The Thatcher and Reagan administrations led a shift towards more market oriented regulation of economies in the Anglo-American countries, including efforts to reduce the power of organized labor. In this paper, we examine the development of employment and labor law in six Anglo-American countries (the U.S., Canada, the U.K., Ireland, Australia, and New Zealand) from the Thatcher/Reagan era to the present. At the outset of the Thatcher/Reagan era, the employment and labor law systems in these countries could be divided into three pairings: the Wagner Act model based industrial relations systems of the United States and Canada; the voluntarist system of collective bargaining and strong unions in the United Kingdom and Ireland; and the highly centralized, legalistic Award systems of Australia and New Zealand. Indeed, such a historical perspective contradicts the idea that there has been a longstanding Anglo-American model of liberal market economic ordering as has sometimes been suggested, e.g. in the varieties of capitalism literature. However, looking at the current state of the employment relations systems in these six countries, we argue that there has been growing convergence in two major areas. There has been a convergence in the area of labour rights toward private ordering of employment relations and away from the idea of work and employment being a matter subject to public ordering. By private ordering, we mean the idea that work and employment terms and conditions are primarily determined at the level of the individual organization, whether through collective bargaining between unions and employers at the organizational level, through individual negotiations, or through unilateral employer establishment of the terms and conditions of employment. The shift away from public ordering of work and employment is most dramatic in the cases of Australia and New Zealand, where the publicly established system of centralized Awards has given way to organizational level ordering of employment relations through workplace or individual level agreements. In the United Kingdom, the shift to greater private ordering is most evident in the breakdown of multi-employer collective bargaining, the weakening of industry wide standards enforced by strong unions, and the growth of nonunion representation at the enterprise level. By contrast, the much lesser degree of change in the labour rights area in North America reflects the historical situation that the Wagner Act model was from the outset a model built around the idea of private ordering. When we turn to the area of employment rights, we also see a convergence across the six Anglo-American countries toward a model in which the role of employment law is to establish a basket of minimum standards that are built into the employment relationship, which can then be improved upon by the parties. Within these general trends, we do see some variation in the degree of convergence on these models of labour and employment rights regulation across the Anglo-American countries. The strongest degree of similarity in adoption of the private ordering in labour rights and the minimum standards basket in employment rights is found in four of the countries: Canada, the United Kingdom, New Zealand and, with recent legislative changes, Australia. Each of these countries has adopted labour laws that favour organizational level economic ordering, but with reasonably substantial protections of trade union organizing and bargaining rights, and a set of minimum employment standards that includes similar sets of minimum wage, basic leave entitlements and unfair dismissal protections. The first outlier in this study is Ireland. The Irish employment relations system stands out as the only one that has continued to have a significant degree of central coordination and public ordering of employment relations. Although there is substantial coordination at the central level, at the organizational level, the Irish system resembles the other Anglo-American countries much more closely, suggesting that it has the potential to evolve in a similar direction. The other outlier is the United States. Structurally its system is similar to the other Anglo-American countries in emphasizing private ordering in labour law and the role of employment law as being to establish a minimum basket of basic standards. However, where the United States diverges from the other countries is that its system has involved a general favouring of the interests of employers over those of employees and organized labour in the implementation of the model
