Voluntary Disclosure and Firm Visibility: Evidence from Firms Pursuing an Initial Public Offering
Drawing on predictions by Merton (1987) regarding the benefits to firms of enhancing visibility with prospective investors, we develop hypotheses for the role of pre-prospectus voluntary disclosure activities in terms of press releases and attendance at investor and industry conferences by firms pursuing an initial public offering (IPO). For a sample of IPOs during 2004â2014 we find that press release disclosures and conference attendance are common pre-IPO disclosure strategies. Tests using the passage of the 2005 Securities Offering Reform as a source of quasi-exogenous variation in pre-prospectus disclosures reveal, consistent with Merton (1987), that disclosures in this regime appear designed to enhance firm visibility, but have little effect on the extent of adverse selection costs. Overall, our evidence suggests that pre-IPO voluntary disclosure strategies provide benefits to newly public firms beyond mitigating informational asymmetries
Screening Procedure for Hemihypertrophy: Preliminary Results of International Multicenter Prospective Study
Introduction: Isolated or congenital hemihypertrophy is a rare disorder characterized by asymmetric overgrowth of one side of the body. This article describes the protocol and preliminary results of a lateral body asymmetry (hemihypertrophy) screening procedure performed in healthy adolescents in a multicenter study. The reported incidence of hemihypertrophy varies between different publications and standardized protocols are needed to improve research in this area.Methods: Our screening program is taking place in Australia, Israel, Mexico, Ukraine and USA. Procedure includes two steps: (1) âthree measurements â three questionsâ screening, or assessment of face, palms, and shins; (2) in-depth assessment of selected cases in order to exclude localized, lesional, and syndrome-related cases as well as body asymmetry within normative range and to select suspected cases of isolated hemihypertrophy. This step includes measurements of various anatomical regions and a detailed questionnaire.Results: At this stage, the screening procedure is completed and the selected participants are advised to refer to medical institutions for further clinical and genetic follow up to exclude possible tumors and other accompanying disorders.Conclusion: We present an easy-to-use selection tool to identify children with suspected IH, which results in the selection of the risk group that may benefit from referral to a pediatrician and a clinical geneticist
Chronic Wasting Disease and Potential Transmission to Humans
Chronic wasting disease (CWD) of deer and elk is endemic in a tri-corner area of Colorado, Wyoming, and Nebraska, and new foci of CWD have been detected in other parts of the United States. Although detection in some areas may be related to increased surveillance, introduction of CWD due to translocation or natural migration of animals may account for some new foci of infection. Increasing spread of CWD has raised concerns about the potential for increasing human exposure to the CWD agent. The foodborne transmission of bovine spongiform encephalopathy to humans indicates that the species barrier may not completely protect humans from animal prion diseases. Conversion of human prion protein by CWD-associated prions has been demonstrated in an in vitro cell-free experiment, but limited investigations have not identified strong evidence for CWD transmission to humans. More epidemiologic and laboratory studies are needed to monitor the possibility of such transmissions
Does Sensationalism Affect Executive Compensation? Evidence from Pay Ratio Disclosure Reform
Beginning in 2018, publicly-traded U.S. firms were required to report the ratio of the chief executive officerâs (CEO) compensation to that of the median employeeâs compensation in the annual proxy statement. Our study examines the effect of the mandated pay ratio disclosure on executive compensation. We find that pay ratio disclosure leads to declines in both total compensation and pay-for-performance sensitivity for CEOs relative to chief financial officers (CFOs). Our effects are strongest for firms that are more sensitive to political pressure. Taken together, our paper provides the first evidence that pay ratio disclosure achieves regulatorsâ goal of curtailing CEO compensation but also leads to an unintended decline in pay-for-performance sensitivity

The Erotic and the Vulgar: Visual Culture and Organized Labor's Critique of U.S. Hegemony in Occupied Japan
This essay engages the colonial legacy of postwar Japan by arguing that the political cartoons produced as part of the postwar Japanese labor movementâs critique of U.S. cultural hegemony illustrate how gendered discourses underpinned,
and sometimes undermined, the ideologies formally represented by visual artists and the organizations that funded them. A significant component of organized
laborâs propaganda rested on a corpus of visual media that depicted women as icons of Japanese national culture. Japanâs most militant labor unions were propagating anti-imperialist discourses that invoked an engendered/endangered nation that accentuated the importance of union roles for men by subordinating, then eliminating, union roles for women
The Guillain-Barre syndrome and the 1992-1993 and 1993-1994 influenza vaccines
BackgroundThe number of reports of influenza-vaccine-associated Guillain-Barré syndrome to the national Vaccine Adverse Event Reporting System increased from 37 in 1992-1993 to 74 in 1993-1994, arousing concern about a possible increase in vaccine-associated risk.
MethodsPatients given a diagnosis of the Guillain-Barré syndrome in the 1992-1993 and 1993-1994 influenza-vaccination seasons were identified in the hospital-discharge data bases of four states. Vaccination histories were obtained by telephone interviews during 1995-1996 and were confirmed by the vaccine providers. Disease with an onset within six weeks after vaccination was defined as vaccine-associated. Vaccine coverage in the population was measured through a random-digit-dialing telephone survey.
ResultsWe interviewed 180 of 273 adults with the Guillain-Barré syndrome; 15 declined to participate, and the remaining 78 could not be contacted. The vaccine providers confirmed influenza vaccination in the six weeks before the onset of Guillain-Barré syndrome for 19 patients. The relative risk of the Guillain-Barré syndrome associated with vaccination, adjusted for age, sex, and vaccine season, was 1.7 (95 percent confidence interval, 1.0 to 2.8; P=0.04). The adjusted relative risks were 2.0 for the 1992-1993 season (95 percent confidence interval, 1.0 to 4.3) and 1.5 for the 1993-1994 season (95 percent confidence interval, 0.8 to 2.9). In 9 of the 19 vaccine-associated cases, the onset was in the second week after vaccination, all between day 9 and day 12.
ConclusionsThere was no increase in the risk of vaccine-associated Guillain-Barré syndrome from 1992-1993 to 1993-1994. For the two seasons combined, the adjusted relative risk of 1.7 suggests slightly more than one additional case of Guillain-Barré syndrome per million persons vaccinated against influenza
Novel desmoplakin mutation: juvenile biventricular cardiomyopathy with left ventricular non-compaction and acantholytic palmoplantar keratoderma
Two sons of a consanguineous marriage developed biventricular cardiomyopathy. One boy died of severe heart failure at the age of 6Â years, the other was transplanted because of severe heart failure at the age of 10Â years. In addition, focal palmoplantar keratoderma and woolly hair were apparent in both boys. As similar phenotypes have been described in Naxos disease and Carvajal syndrome, respectively, the genes for plakoglobin (JUP) and desmoplakin (DSP) were screened for mutations using direct genomic sequencing. A novel homozygous 2Â bp deletion was identified in an alternatively spliced region of DSP. The deletion 5208_5209delAG led to a frameshift downstream of amino acid 1,736 with a premature truncation of the predominant cardiac isoform DSP-1. This novel homozygous truncating mutation in the isoform-1 specific region of the DSP C-terminus caused Carvajal syndrome comprising severe early-onset heart failure with features of non-compaction cardiomyopathy, woolly hair and an acantholytic form of palmoplantar keratoderma in our patient. Congenital hair abnormality and manifestation of the cutaneous phenotype in toddler age can help to identify children at risk for cardiac death
