The cultural grammar of governance: The UK Code of Corporate Governance, reflexivity, and the limits of 'soft' regulation

We identify limits of ‘reflexive governance’ by examining the UK Code of Corporate Governance that is celebrated for its ‘reflexivity’. By placing the historical genesis of the Code within its politico-economic context, it is shown how its scope and penetration is impeded by a shallow, ‘single loop’ of reflexivity. Legitimized by agency theory, the Code is infused by a ‘cultural grammar’ that perpetuates relations of shareholder primacy as it restricts accountability to narrow forms of information disclosure directed exclusively at shareholders. Engagement of a deeper, ‘double loop’ reflexivity allows account to be taken of the historical conditions and theoretical conceptions that shape practices and outcomes of corporate governance. Only then is it possible to disclose, challenge and reform narrow conceptions, boundaries and workings of ‘reflexive governance’

An evolutionary approach to international political economy: the case of corporate tax avoidance

Corporate tax avoidance is both widespread and diverse in its practical mechanics. The scope of the phenomenon often leads economists to conclude that in the jungle of economic competition, tax planning (or optimisation) is among the necessary tools to ensure the survival of the fittest. This theory is increasingly associated with a Darwinian theory of economic evolution. In this paper, I develop a contrasting framework of the evolutionary political economy of corporate tax avoidance. Analysing core concepts of Old Institutionalist Economics (OIE), I examine the core drivers of corporate tax avoidance in a globalised system of states. The major contrast, I find, is between that of the corporate and legal personality and the institutional environment in which it operates. Historically, each corporate entity has been considered a separate legal person, yet a series of ‘mutations’ of incorporations laws created a widening gap between theory and reality, and these, in turn, give rise to tax arbitrage. Narrowing this gap, however, impinges on another venerable historical institution, the institution of sovereignty and sovereign inequality

ANO1 amplification and expression in HNSCC with a high propensity for future distant metastasis and its functions in HNSCC cell lines

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) is associated with poor survival. To identify prognostic and diagnostic markers and therapeutic targets, we studied ANO1, a recently identified calcium-activated chloride channel (CaCC). METHODS: High-resolution genomic and transcriptomic microarray analysis and functional studies using HNSCC cell line and CaCC inhibitors. RESULTS: Amplification and overexpression of genes within the 11q13 amplicon are associated with the propensity for future distance metastasis of HPV-negative HNSCC. ANO1 was selected for functional studies based on high correlations, cell surface expression and CaCC activity. ANO1 overexpression in cells that express low endogenous levels stimulates cell movement, whereas downregulation in cells with high endogenous levels has the opposite effect. ANO1 overexpression also stimulates attachment, spreading, detachment and invasion, which could account for its effects on migration. CaCC inhibitors decrease movement, suggesting that channel activity is required for the effects of ANO1. In contrast, ANO1 overexpression does not affect cell proliferation. INTERPRETATION: ANO1 amplification and expression could be markers for distant metastasis in HNSCC. ANO1 overexpression affects cell properties linked to metastasis. Inhibitors of CaCCs could be used to inhibit the tumourigenic properties of ANO1, whereas activators developed to increase CaCC activity could have adverse effects

Group subsidiaries, tax minimization and offshore financial centres: Mapping organizational structures to establish the ‘in-betweener’ advantage

International business and public policy research have examined the techniques that multinational enterprises (MNEs) use to shift revenues to subsidiaries in offshore financial centres (OFCs) in order to minimize tax liability and arbitrage for their advantage. While study of such tax arbitrage strategies has looked to geographical locations and legal dimensions to better understand these strategies, it has ignored the structural and organizational relationship between MNEs and their subsidiaries. We define two distinct types of OFC-based corporate entities based on their location among and apparent control over other MNE affiliates: ‘stand-alone’ OFCs at the end of a chain of MNE subsidiaries; and ‘in-betweener’ OFCs with equity control over further entities and hence apparent flexibility to redirect profits to other MNE subsidiaries further down the chain. We hypothesize that when MNEs have in-betweener OFCs controlling a substantial share of overall MNE profits, this indicates greater MNE interest in aggressive tax planning (ATP). We then evaluate empirical support for our claims based on an ‘equity mapping’ approach identifying stand-alone and in-betweener OFCs in 100 of the largest MNEs operating globally. This study demonstrates that a key factor determining tax arbitrage is not the amount of value registered on OFC subsidiaries’ balance sheets, but rather the portion of the group’s operating revenues and net income controlled by OFC subsidiaries. National taxing authorities could benefit from tracking in-betweener OFC locations and behaviour to counter ATP strategies, decrease sovereign arbitrage, and increase MNE tax revenue

État des travaux normatifs dans le domaine du mesurage des radionucléides dans l'environnement

Les préoccupations concernant la présence de substances radioactives dans l'environnement conduisent régulièrement à des expertises sur les niveaux d'activité des radionucléides dans l'environnement et à des évaluations de leurs impacts radiologiques sur les populations humaines. La crédibilité de ces expertises repose en partie sur la qualité et la fiabilité des mesurages. Ce document présente les systèmes d'organisations de la normalisation, nationale et internationale, ainsi que les documents normatifs publiés et les travaux de normalisation en cours relatifs à la métrologie des radionucléides présents dans les matrices environnementales
