MAD water: integrating modular, adaptive, and decentralized approaches for water security in the climate change era
Centralized water infrastructure has, over the last century, brought safe and reliable drinking water to much of the world. But climate change, combined with aging and underfunded infrastructure, is increasingly testing the limits ofâand reversing gains made byâthis approach. To address these growing strains and gaps, we must assess and advance alternatives to centralized water provision and sanitation. The water literature is rife with examples of systems that are neither centralized nor networked, yet meet water needs of local communities in important ways, including: informal and hybrid water systems, decentralized water provision, community-based water management, small drinking water systems, point-of-use treatment, small-scale water vendors, and packaged water. Our work builds on these literatures by proposing a convergence approach that can integrate and explore the benefits and challenges of modular, adaptive, and decentralized (âMADâ) water provision and sanitation, often foregrounding important advances in engineering technology. We further provide frameworks to evaluate justice, economic feasibility, governance, human health, and environmental sustainability as key parameters of MAD water system performance

Enforcing higher labour standards within developing country value chains: consequences for MNEs and informal actors in a dual economy
The 2013 Rana Plaza disaster led external stakeholders to insist on higher labour standards in apparel global value chains (GVCs). Stakeholders now expect MNEs to take âfull-chainâ responsibility. However, the increased monitoring and enforcement costs of a large network of suppliers have been non-trivial. MNEs instead implement a âcascading complianceâ approach, coupled with a partial re-internalization. Elevated costs are further exacerbated in developing countries where the informal and formal sector are linked, and cost competitiveness greatly depends on this duality. Monitoring actors in the informal sector is difficult, and few informal actors can achieve compliance. GVCs have therefore reduced informal sector engagement by excluding non-compliant actors and investing in greater automation. By seeking to strictly enforce compliance, MNEs are attenuating some of the positive effects of MNE investment, particularly the prospects for employment creation (especially among women), and enterprise growth in the informal sector. I discuss how these observations might inform other cross-disciplinary work in development, ethics, and sociology. Finally, I note implications for IB theory from the disparities between the ownership, control and responsibility boundaries of the firm

Insulin secretion deficits in a Prader-Willi syndrome β-cell model are associated with a concerted downregulation of multiple endoplasmic reticulum chaperones.
Prader-Willi syndrome (PWS) is a multisystem disorder with neurobehavioral, metabolic, and hormonal phenotypes, caused by loss of expression of a paternally-expressed imprinted gene cluster. Prior evidence from a PWS mouse model identified abnormal pancreatic islet development with retention of aged insulin and deficient insulin secretion. To determine the collective roles of PWS genes in β-cell biology, we used genome-editing to generate isogenic, clonal INS-1 insulinoma lines having 3.16 Mb deletions of the silent, maternal- (control) and active, paternal-allele (PWS). PWS β-cells demonstrated a significant cell autonomous reduction in basal and glucose-stimulated insulin secretion. Further, proteomic analyses revealed reduced levels of cellular and secreted hormones, including all insulin peptides and amylin, concomitant with reduction of at least ten endoplasmic reticulum (ER) chaperones, including GRP78 and GRP94. Critically, differentially expressed genes identified by whole transcriptome studies included reductions in levels of mRNAs encoding these secreted peptides and the group of ER chaperones. In contrast to the dosage compensation previously seen for ER chaperones in Grp78 or Grp94 gene knockouts or knockdown, compensation is precluded by the stress-independent deficiency of ER chaperones in PWS β-cells. Consistent with reduced ER chaperones levels, PWS INS-1 β-cells are more sensitive to ER stress, leading to earlier activation of all three arms of the unfolded protein response. Combined, the findings suggest that a chronic shortage of ER chaperones in PWS β-cells leads to a deficiency of protein folding and/or delay in ER transit of insulin and other cargo. In summary, our results illuminate the pathophysiological basis of pancreatic β-cell hormone deficits in PWS, with evolutionary implications for the multigenic PWS-domain, and indicate that PWS-imprinted genes coordinate concerted regulation of ER chaperone biosynthesis and β-cell secretory pathway function
