    This is the final version of the article. Available from the publisher via the DOI in this record.Low incomes, limited financial literacy, fraud, and deception are just a few of the many intractable economic and social factors that contribute to the financial difficulties that households face today. Addressing these issues directly is difficult and costly. But poor financial outcomes also result from systematic psychological tendencies, including imperfect optimization, biased judgments and preferences, and susceptibility to inļ¬‚uence by the actions and opinions of others. Some of these psychological tendencies and the problems they cause may be countered by policies and interventions that are both low cost and scalable. We detail the ways that these behavioral factors contribute to consumers' financial mistakes and suggest a set of interventions that the federal government, in its dual roles as regulator and employer, could feasibly test or implement to improve household financial outcomes in a variety of domains: retirement, short-term savings, debt management, the take-up of government benefits, and tax optimization

    PKCĪ“ regulates force signaling during VEGF/CXCL4 induced dissociation of endothelial tubes

    Wound healing requires the vasculature to re-establish itself from the severed ends; endothelial cells within capillaries must detach from neighboring cells before they can migrate into the nascent wound bed to initiate angiogenesis. The dissociation of these endothelial capillaries is driven partially by platelets' release of growth factors and cytokines, particularly the chemokine CXCL4/platelet factor-4 (PF4) that increases cell-cell de-adherence. As this retraction is partly mediated by increased transcellular contractility, the protein kinase c-Ī“/myosin light chain-2 (PKCĪ“/MLC-2) signaling axis becomes a candidate mechanism to drive endothelial dissociation. We hypothesize that PKCĪ“ activation induces contractility through MLC-2 to promote dissociation of endothelial cords after exposure to platelet-released CXCL4 and VEGF. To investigate this mechanism of contractility, endothelial cells were allowed to form cords following CXCL4 addition to perpetuate cord dissociation. In this study, CXCL4-induced dissociation was reduced by a VEGFR inhibitor (sunitinib malate) and/or PKCĪ“ inhibition. During combined CXCL4+VEGF treatment, increased contractility mediated by MLC-2 that is dependent on PKCĪ“ regulation. As cellular force is transmitted to focal adhesions, zyxin, a focal adhesion protein that is mechano-responsive, was upregulated after PKCĪ“ inhibition. This study suggests that growth factor regulation of PKCĪ“ may be involved in CXCL4-mediated dissociation of endothelial cords. Ā© 2014 Jamison et al

    Prisoners of the Capitalist Machine: Captivity and the Corporate Engineer

    Get PDF
    This chapter will focus on how engineering practice is conditioned by an economic system which promotes production for profit and economic growth as an end in itself. As such it will focus on the notion of the captivity of engineering which emanates from features of the economic system. By drawing on Critical Realism and a Marxist literature, and by focusing on the issues of safety and sustainability (in particular the issue of climate change), it will examine the extent to which disasters and workplace accidents result from the economic imperative for profitable production and how efforts by engineers to address climate change are undermined by an on-going commitment to growth. It will conclude by arguing that the structural constraints on engineering practice require new approaches to teaching engineers about ethics and social responsibility. It will argue that Critical Realism offers a framework for the teaching of engineering ethics which would pay proper attention to the structural context of engineers work without eliminating the possibility of engineers working for radical change

    Creative Compliance, Constructive Compliance: Corporate Environmental Crime and the Criminal Entrepreneur

    Get PDF
    Purpose While corporations may embrace the concepts of social and environmental responsibility, numerous examples exist to show corporations claiming to act sustainably and responsibly, while simultaneously showing disregard for the communities in which they operate and causing considerable environmental damage. This chapter argues that such activities illustrate a particular notion of Baumolā€™s (1990) criminal entrepreneurialism where both creative and constructive compliance combine to subvert environmental regulation and its enforcement. Design/methodology/approach This chapter employs a case study approach assessing the current corporate environmental responsibility landscape against the reality of corporate environmental offending. Its case study shows seemingly repeated environmental 'offending' by Shell Oil against a backdrop of the company claiming to have integrated environmental monitoring and scrutiny into its operating procedures. Findings The chapter concludes that corporate assertion of environmental credentials is itself often a form of criminal entrepreneurship where corporations embrace voluntary codes of practice and self-regulation while internally promoting the drive for success and profitability and/or avoidance of the costs of true environmental compliance deemed too high. As a result this chapter argues that responsibility for environmental damage requires regulation to ensure corporate responsibility for environmental damage. Originality/value The chapter employs a green criminological perspective to its analysis of corporate social responsibility and entrepreneurship. Thus it considers not just strict legal definitions of crime and criminal behaviour but also the overlap between the legal and the illegal and the preference of Governments to use administrative or civil penalties as tools to deal with corporate environmental offending

    The Origins Space Telescope

    The Origins Space Telescope will trace the history of our origins from the time dust and heavy elements permanently altered the cosmic landscape to present-day life. How did galaxies evolve from the earliest galactic systems to those found in the universe today? How do habitable planets form? How common are life-bearing worlds? To answer these alluring questions, Origins will operate at mid- and far-infrared wavelengths and offer powerful spectroscopic instruments and sensitivity three orders of magnitude better than that of Herschel, the largest telescope flown in space to date. After a 3 year study, the Origins Science and Technology Definition Team will recommend to the Decadal Survey a concept for Origins with a 5.9-m diameter telescope cryo cooled to 4.5 K and equipped with three scientific instruments. A mid-infrared instrument (MISC-T) will measure the spectra of transiting exoplanets in the 2.8 20 m wavelength range and offer unprecedented sensitivity, enabling definitive biosignature detections. The Far-IR Imager Polarimeter (FIP) will be able to survey thousands of square degrees with broadband imaging at 50 and 250 m. The Origins Survey Spectrometer (OSS) will cover wavelengths from 25 588 m, make wide-area and deep spectroscopic surveys with spectral resolving power R ~ 300, and pointed observations at R ~ 40,000 and 300,000 with selectable instrument modes. Origins was designed to minimize complexity. The telescope has a Spitzer-like architecture and requires very few deployments after launch. The cryo-thermal system design leverages JWST technology and experience. A combination of current-state-of-the-art cryocoolers and next-generation detector technology will enable Origins natural background limited sensitivity
