First Measurement of Timelike Compton Scattering.
No full textWe present the first measurement of the timelike Compton scattering process,
γp → p\u27 γ* (γ* →e+ e −) obtained with the CLAS12 detector at Jefferson Lab. The photon beam polarization and the decay lepton angular asymmetries are reported in the range of timelike photon virtualities 2.25 \u3c Q\u272 \u3c 9 GeV2, squared momentum transferred 0.1 \u3c -t \u3c 0.8 GeV2, and average total center-of-mass energy squared s = 14.5 GeV2. The photon beam polarization asymmetry, similar to the beam-spin asymmetry in deep virtual Compton scattering, is sensitive to the imaginary part of the Compton form factors and provides a way to test the universality of the generalized parton distributions. The angular asymmetry of the decay leptons accesses the real part of the Compton form factors and thus the D-term in the parametrization of the generalized parton distributions
Demographics and Monetary Policy Shocks
No full textWe show that consumption expenditures for older households are more responsive to monetary policy shocks than for young- or middle-aged households. A one-standard-deviation expansionary monetary policy shock induces a statistically significant and quantitatively large (1.7%) increase in aggregate consumption for old households over the ensuing 3 years. The responses for young- and middle-aged households are smaller and not statistically significant. We also present evidence, suggesting that life-cycle wealth effects play a role in driving the responses. We then build the wealth mechanism into a partial equilibrium life-cycle model, which can qualitatively match the empirical patterns
The Transgressive Rhetoric of Standup Comedy in China
Get PDFPublic discourse under authoritarian rule is not monolithic. Yet how popular rhetoric engages with the hegemonic rhetoric in the same discursive space remains understudied. This article examines the rhetoric of a standup comedy show in China, streamed online and widely popular among Chinese millennials, to understand how alternative views on social issues can coexist with the hegemonic rhetoric. Using critical discourse analysis, it argues that some standup comedy performances transgress the hegemonic rhetoric of positive energy without outright subversion. Comedians use subversive affirmation, self-deprecation, ambiguity, absurd fantasy, and irony to present alternative viewpoints on social issues of broad interest, such as the neoliberal work culture and gender norms. The subtle yet powerful transgressions introduce previously marginal views into the public discourse, diminishing the aura of wide acceptance and authority assumed by the hegemonic rhetoric. The standup comedy performances thus open up new discursive pathways towards non-state-sanctioned views on important social issues
COVID-19 and Rule 10b-5
Get PDFThe COVID-19 pandemic presented wide-ranging challenges for businesses. Not the least of these is compliance with federal securities laws, including the prohibition—most notably under SEC Rule 10b-5—on materially deceptive statements made to the public. Both the SEC, in its role as enforcer of the law, and private parties, seeking to represent classes of aggrieved investors, have filed complaints asserting that corporations and others have engaged in deception of investors regarding matters pertaining to COVID-19. Some of these claims relate to disclosures regarding testing kits for the virus as well as development of vaccines. Other complaints allege faulty disclosure on the effect of the pandemic on the market for a company’s products and services that are not themselves related to the pandemic, such as claims against cruise lines that suspended operations. This article presents the legal framework for claims based on Rule 10b-5, SEC guidance on how COVID-19 affects compliance with disclosure requirements for public companies, and the issues that have emerged in the claims already filed. This analysis demonstrates that almost any public reporting company faces the risk of inadequate disclosure and the temptation to withhold or misstate material facts in a time of financial stress
Well-being in the time of COVID-19: Do metaphors and mindsets matter?
Get PDFCommunications about the Coronavirus Disease 2019 (COVID-19) often employ metaphors, which can help people understand complex issues. For example, public health messages may focus on “fighting” the disease, attempting to rouse people to action by instilling a sense of urgency. In contrast, change-focused metaphors may foster growth mindsets and self-efficacy—cornerstones of well-being and action. We randomly assigned participants to read one of two articles—either an article about coronavirus that focused on fighting the war or an article that highlighted the possibility of change. In Study 1 (N = 426), participants who read the war, relative to the change, message reported lower growth mindsets and self-efficacy and these in turn, predicted lower well-being and weaker intentions to engage in health behaviours. In Study 2, (N = 702), we sought to replicate findings and included a no treatment control. We failed to replicate the effects of message condition, although both messages predicted greater self-efficacy compared to the control. Similar to Study 1, growth mindsets predicted intentions to engage in recommended health behaviours and self-efficacy predicted both well-being and action. We discuss theoretical reasons for discrepancies as well as practical applications for developing public health communications
Emergent market innovation: A longitudinal study of technology-driven capability development and institutional work
No full textExtant literature focuses primarily on deliberate, proactive market-shaping efforts to understand changes in markets. This paper explores how emergent, incremental activities might unintentionally prompt market innovation due to the interactions of capability development and its required institutional work. Using a critical case method, we study a firm that successfully challenged established market logic by systematically changing its capabilities. A longitudinal field study reveals that capability development demands induce changes to institutional foundations; then, as institutions change, further capabilities can be developed, all of which may instigate wider market innovation outcomes. This study conceptualizes this intricate, iterative process, as well as its evolutionary market innovation outcomes. The proposed three-level capability model can guide firms striving to offer new and innovative services. The authors also detail a three-stage research design methodology that can help research and practice gain in-depth understanding of both emergent unintentional market innovation and strategic deliberate market-shaping activities
