Designing the tools of the trade: How corporate social responsibility consultants and their tool-based practices created market shifts

Combining insights from the sociology of markets and studies of consultants, this article examines the tool-based practices by which market actors enable the agencing of the supply and demand of the market in ways that shape market’s trajectory. Building on 30 interviews and a rich set of secondary data, we provide an analysis of the development of a market for consultancy products and services for Corporate Social Responsibility (CSR) in the province of Quebec (Canada). We analytically induced six tool-based practices by which consultants contributed to the agencing of the market, and our results show how these practices collectively created market shifts. Our analysis offers new insights into the processes by which consultants’ tool-based practices produce market shifts, embed environmental and social concerns within market mechanisms, and ‘vascularize’ markets

Consultants as discreet corporate change agents for sustainability: Transforming organizations from the outside-in

Despite their central role in the construction and development of the market for virtues as well as in the design, implementation, and evaluation of corporate sustainability strategies and governmental sustainability policies, sustainability consultants remain at best “hidden” corporate change agents. In this paper, we bring sustainability consultants back to the fore to account for how these actors discreetly regulate and shape contemporary sustainability transformations from the outside-in. We do so first by unpacking various roles of consultants as engineers, market builders, power vehicles, boundary workers, issue translators, and soft regulators; then we conceptualize how, through these roles, they contribute to empowering, legitimizing but also potentially supplanting and undermining the activities of corporate change agents operating inside corporations. We finally propose some research orientations for studying further the role of sustainability consultants in corporate transformations towards sustainability

Eddy viscosity for resolvent-based jet noise models

Response modes computed via linear resolvent analysis have shown promising results for qualitatively modeling both the hydrodynamic and acoustic fields in jets when compared to data-deduced modes from high-fidelity, large-eddy simulations (LES). For an improved quantitative prediction of the near- and far-field, the role of Reynolds stresses must also be considered. In this study, we propose a methodology to deduce an eddy-viscosity model that optimally captures the nonlinear forcing of resolvent modes. The methodology is based on the maximization of the projection between resolvent analysis and spectral proper orthogonal decomposition (SPOD) modes using a Lagrangian optimization framework. For a Mach 0.4 round, isothermal, turbulent jet, four methods are used to increase the projection coefficients: linear damping, spatially constant eddy-viscosity field, a turbulent kinetic energy derived viscosity field, and an optimized eddy-viscosity field. The resulting projection coefficients for the optimized eddy-viscosity field between SPOD and resolvent can be increased to over 90% for frequencies in the range St = 0.35−1 with significant improvements to St < 0.35. We find that the use of a frequency-independent turbulent kinetic energy turbulent viscosity model produces modes closely inline with optimal results, providing a preliminary eddy-viscosity resolvent model for jets

A Parabolised Stability Equation based Broadband Shock-Associated Noise Model

International audienceWavepacket models have been used extensively to predict the noise produced from turbulent subsonic and supersonic jets. Such wavepackets, which represent the organised structures of the flow, are solutions to the linearised Navier-Stokes equations. Using a kinematic two-point model, Wong et al. [1] have indicated the importance of incorporating coherence decay in modelling broadband shock-associated noise (BBSAN) in supersonic jets. In this work, we aim to improve the model by using solutions from linear parabolised stability equations (PSE) to model the wavepacket part of the BBSAN source. The two-point coherence of the wavepackets is obtained from large-eddy simulation (LES) data of a M j = 1.5 fully-expanded isothermal supersonic jet [2]. The aim is to build a dynamic sound-source model for BBSAN that would improve on the simplified line-source model proposed by Wong et al. [3]. We find that a frequency dependent coherence decay length scale is important in order to suppress the higher-order harmonic peaks [4] and to obtain the correct BBSAN peak shape. Moderate agreement up to St = 1 was found between the current noise predictions and those from experimental data. I.

Big audit firms as regulatory intermediaries in transnational labor governance

Due diligence and corporate disclosure initiatives effectively expand the role of professional service firms as regulatory intermediaries in the governance of conditions of production in global supply chains. In this paper, we examine the rise of the “Big Four” audit firms in the market for services connected to transnational labor governance. Through a qualitative case study of audit firms in modern slavery governance, we argue that the Big Four's political repertoire for transnational labor governance expands beyond the roles that are typically linked to their services, and promotes an agenda that touches on key debates on what constitutes proper transnational labor governance. Big audit firms engage in a variety of informal and covert influencing practices and are shown to promote an agenda of incrementalist soft‐law labor governance, opposing concrete performance targets, binding public regulation and an independent watchdog role for civil society

Mammalian microRNA: an important modulator of host-pathogen interactions in human viral infections

MicroRNAs (miRNAs), which are small non-coding RNAs expressed by almost all metazoans, have key roles in the regulation of cell differentiation, organism development and gene expression. Thousands of miRNAs regulating approximately 60æ% of the total human genome have been identified. They regulate genetic expression either by direct cleavage or by translational repression of the target mRNAs recognized through partial complementary base pairing. The active and functional unit of miRNA is its complex with Argonaute proteins known as the microRNA-induced silencing complex (miRISC). De-regulated miRNA expression in the human cell may contribute to a diverse group of disorders including cancer, cardiovascular dysfunctions, liver damage, immunological dysfunction, metabolic syndromes and pathogenic infections. Current day studies have revealed that miRNAs are indeed a pivotal component of host-pathogen interactions and host immune responses toward microorganisms. miRNA is emerging as a tool for genetic study, therapeutic development and diagnosis for human pathogenic infections caused by viruses, bacteria, parasites and fungi. Many pathogens can exploit the host miRNA system for their own benefit such as surviving inside the host cell, replication, pathogenesis and bypassing some host immune barriers, while some express pathogen-encoded miRNA inside the host contributing to their replication, survival and/or latency. In this review, we discuss the role and significance of miRNA in relation to some pathogenic viruses
