An Alternative Approach to Canadian House of Commons Reform

Empowering backbench Members of Parliament in order to restore the effectiveness of the House of Commons has been a central theme in Canadian parliamentary reform for at least fifty years, but results are widely seen as disappointing. This article argues that unrealistic expectations, fostered by adherence to a traditional conception of the Westminster model of representative and responsible government, are part of the problem. A modernized conception of parliamentary government, recognizing the House as a forum for competing political parties between elections, could help us to better understand the House and improve its contribution to democratic governance. The proposed approach suggests innovative procedural options for legislative debate, Question Period, and other activities. It also offers a consistent basis for addressing issues such as floor-crossing, coalitions, and prorogations. More broadly, it points to the need for an integrated approach to the House, elections, political parties, public education, and citizen engagement in order to respond to contemporary democratic challenges.     

Conceptualising Australia's tradition of pragmatic federalism

This article reviews existing scholarly debates about Australia's pragmatic federalism and seeks to refine it conceptually. It does so against the background of burgeoning international governance literature informed by insights from philosophical pragmatism, as well as in the context of disjuncture in Australian inter-governmental experiences. Pragmatic federalism is posed not merely as a one-dimensional notion referencing a series of ad hoc inter-governmental arrangements over time. Rather, it is conceptualised as multi-dimensional and encapsulating a confined range of institutional designs and postures that can (potentially) be observed across different policy fields and over time. An initial demonstration of the utility of the heuristic to recent empirical experience and change is presented. The consequence is more serious engagement with both the formal and informal features that characterise inter-governmental arrangements at different levels of government, and attention to the degrees to which dialogue and practices are connected.

本文考察了有关澳大利亚实用联邦制的学术辩论,并试图将其概念精炼。本文写作背景包含了开始出现的国际治理文献、哲学实用主义以及澳大利益政府间关系的裂变。实用主义联邦制并非仅仅是参考了一系列政府间安排的单面观念。它是一个多面的、包括一系列制度方案和姿态,而这些在不同政策领域内,在很长时间内都是可以观察到的。本文对近年的实证经验及变化的阐释功用做了初步的说明。最后是对于不同政府级别上的政府间正式及非正式特征更为严肃的介入,对于对话与实践关联程度的关注。     

Fluid effect on hydraulic fracture propagation behavior: a comparison between water and supercritical CO2‐like fluid

The initiation of hydraulic fractures during fluid injection in deep formations can be either engineered or induced unintentionally. Upon injection of CO₂, the pore fluids in deep formations can be changed from oil/saline water to CO₂ or CO₂ dominated. The type of fluid is important not only because the fluid must fracture the rock, but also because rocks saturated with different pore fluids behave differently. We investigated the influence of fluid properties on fracture propagation behavior by using the cohesive zone model in conjunction with a poroelasticity model. Simulation results indicate that the pore pressure fields are very different for different pore fluids even when the initial field conditions and injection schemes (rate and time) are kept the same. Low viscosity fluids with properties of supercritical CO₂ will create relatively thin and much shorter fractures in comparison with fluids exhibiting properties of water under similar injection schemes. Two significant times are recognized during fracture propagation: the time at which a crack ceases opening and the later time point at which a crack ceases propagating. These times are very different for different fluids. Both fluid compressibility and viscosity influence fracture propagation, with viscosity being the more important property. Viscosity can greatly affect hydraulic conductivity and the leak‐off coefficient. This analysis assumes the in‐situ pore fluid and injected fluid are the same and the pore space is 100% saturated by that fluid at the beginning of the simulation.     

Noril'sk Nickel: A Global Company?

Two specialists on Russia's minerals industries examine the evidence supporting the argument that the Russian mining conglomerate Noril'sk Nickel can be viewed as a global company. Included among the criteria they assess are the geographic dispersion of the company's markets and operations, the diversified and multinational character of its ownership, whether it has matched the performance standards set by its major international competitors, and the effect of the company's ownership presence on the management style of its foreign operations. A particular focus is on how an ongoing conflict between two major Russian oligarch shareholders (Vladimir Potanin and Oleg Deripaska) has shaped Noril'sk Nickel's ownership and management structure, which is characterized by the continued (background) presence of the state, the lack of any organized policy for training a multinational management cohort, and the absence of a major block of foreign shareholders. In the end, they conclude that Noril'sk Nickel is not a genuinely global but rather a Tier-1 Russian company, albeit one with a global scale of operations.     

Thermal convection in faulted extensional sedimentary basins: theoretical results from finite-element modeling

Thermal convection has the potential to be a significant and widespread mechanism of fluid flow, mass transport, and heat transport in rift and other extensional basins. Based on numerical simulation results, large‐scale convection can occur on the scale of the basin thickness, depending on the Rayleigh number for the basin. Our analysis indicates that for syn‐rift and early post‐rift settings with a basin thickness of 5 km, thermal convection can occur for basal heat flows ranging from 80 to 150 mW m^?2, when the vertical hydraulic conductivity is on the order of 1.5 m year^?1 and lower. The convection cells have characteristic wavelengths and flow patterns depending on the thermal and hydraulic boundary conditions. Steeply dipping extensional faults can provide pathways for vertical fluid flow across large thicknesses of basin sediments and can modify the dynamics of thermal convection. The presence of faults perturbs the thermal convective flow pattern and can constrain the size and locations of convection cells. Depending on the spacing of the faults and the hydraulic properties of the faults and basin sediments, the convection cells can be spatially organized to align with adjacent faults. A fault‐bounded cell occurs when one convection cell is constrained to occupy a fault block so that the up‐flow zone converges into one fault zone and the down‐flow zone is centred on the adjacent fault. A fault‐bounded cell pair occurs when two convection cells occupy a fault block with the up‐flow zone located between the faults and the down‐flow zones centred on the adjacent faults or with the reverse pattern of flow. Fault‐bounded cells and cell pairs can be referred to collectively as fault‐bounded convective flow. The flow paths in fault‐bounded convective flow can be lengthened significantly with respect to those of convection cells unperturbed by the presence of faults. The cell pattern and sense of circulation depend on the fault spacing, sediment and fault permeabilities, lithologic heterogeneity, and the basal heat flow. The presence of fault zones also extends the range of conditions for which thermal convection can occur to basin settings with Rayleigh numbers below the critical value for large‐scale convection to occur in a basin without faults. The widespread potential for the occurrence of thermal convection suggests that it may play a role in controlling geological processes in rift basins including the acquisition and deposition of metals by basin fluids, the distribution of diagenetic processes, the temperature field and heat flow, petroleum generation and migration, and the geochemical evolution of basin fluids. Fault‐bounded cells and cell pairs can focus mass and heat transport from longer flow paths into fault zones, and their discharge zones are a particularly favourable setting for the formation of sediment‐hosted ore deposits near the sea floor.

Global finance and the German model: German corporations, market incentives, and the management of employer-sponsored pension institutions

Where there was a settled political geography of state power and responsibilities, the remarkable growth of global finance has put enormous pressure on national economic, political and social institutions. Furthermore, the looming crisis facing many continental European social security systems has raised many doubts about the long-term viability of the German model compared to its Anglo-American rivals. In this context, large German corporations have sought ways of sustaining their global competitiveness by, in part, restructuring their national and regional commitments. To illustrate, in this paper we concentrate on the nature and organization of German employer-sponsored pension institutions in relation to Anglo-American management practice. Two issues drive the analysis. One has to do with an emerging coalition between corporate management and shareholders with respect to the market value of the firm. The second issue has to do with the allocation of risk and uncertainty between the social partners when negotiating the financing and final value of promised retirement income. The institutional framework of collective decision-making common to many of Germany's largest firms is under pressure; three models of investment decision making relevant to pension assets and liabilities are used to illustrate this point. In doing so, we suggest that the German model is more fragile than commonly realized. We also suggest that Anglo-American management practices have penetrated and affected German corporate (national and regional) institutions and regulations. The social market lauded by advocates of stakeholder capitalism is changing rapidly, at least in the sphere of large firms and global finance.
