Abstract:
“The advantage of a dual-class share structure is that it protects entrepreneurial management from the demands of ordinary shareholders. The disadvantage of a dual-class share structure is that it protects entrepreneurial management from the demands of shareholders.” Issuing dual classes of stock has become hotly debated since two major events transpired in 2014: (1) Facebook acquired WhatsApp for $19 billion and (2) Alibaba chose to list its shares on the New York Stock Exchange (NYSE) instead of the Hong Kong Exchange. Because dual-class managers, like those at Facebook and Alibaba, retain a

Purpose This study aims to examine institutional ownership of companies that go public with dual-class share structures. Design/methodology/approach Several recent studies have discussed the potential advantages and disadvantages of the dual-class structure, which allows founders and insiders to maintain control of the firms they created through superior voting rights. Institutional investors oppose the dual-class structure, arguing that inferior voting rights make it difficult to respond to poor governance or performance.

Sustainable development is a goal shared by all nations across the globe in the 21st century. Companies with a dual-class share structure in China face problems in their pursuit of sustainable development, such as unclear definition of laws and regulations, increased costs of agencies, defective supervision mechanisms, and insufficient information disclosure. Therefore, it is necessary to identify rules, optimize corporate governance, strengthen the supervision mechanism, and improve information disclosure to safeguard the investors’ legitimate rights, maintain market stability, and secure eco

Using the comprehensive sample of dual class firms compiled by Gompers, Ishii, and Metrick (2010), we find that dual class firms tend to borrow at lower interest rates and for longer maturities but face more covenants, especially performance based covenants. Our results are robust to corrections for the endogenous choice of dual class share structures. We also find that the returns earned by the stocks of these dual class firms have lower volatility.

SUMMARY: This paper investigates whether audit fees vary with the wedge between cash flow rights and control rights arising from the presence of dual-class share structures. Dual-class shares exist in firms having two or more classes of shares with disproportionate voting rights. They affect audit fees through their effect on the supply for audit services. External auditors conduct wider (narrower) scope audits depending on whether dual-class shares increase (decrease) audit risk and/or auditor business risk. Wider (narrower) scope audits are more (less) costly for the auditors and for their c

Cardiomyopathy is a leading cause of death for Duchenne muscular dystrophy. Here, we find that the mineralocorticoid receptor (MR) and glucocorticoid receptor (GR) can share common ligands but play distinct roles in dystrophic heart and skeletal muscle pathophysiology. Comparisons of their ligand structures indicate that the Δ9,11 modification of the first-in-class drug vamorolone enables it to avoid interaction with a conserved receptor residue (N770/N564), which would otherwise activate transcription factor properties of both receptors. Reporter assays show that vamorolone and eplerenone are

Abstract:
HLA-B27- responder cells were stimulated in vitro with HLA-B27.1+ lymphoblastoid cell lines, and alloreactive CTL clones were obtained by limiting dilution. Three of these clones specifically lysed B27.1+ targets. In addition, they also lysed homozygous DR2 targets with various degrees of efficiency, depending on the Dw specificity of the target cell. All three clones possessed a homogeneous CD3+,CD8+,CD4- phenotype and were also homogeneous upon subcloning. Cold-target inhibition analyses showed mutual inhibition of B27.1 target lysis by DR2 targets and vice versa. Lysis of B27.1 targets was

Abstract:
It is shown that a massless scalar probe reveals a universal near-horizon conformal structure for a wide class of black holes, including the BTZ. The central charge of the corresponding Virasoro algebra contains information about the black hole. With a suitable quantization condition on the central charge, the CFT associated with the black hole in our approach is consistent with the recent observation of Witten, where the dual theory for the BTZ in the AdS/CFT framework has been identified with the construction of Frenkel, Lepowsky and Meurman. This CFT admits the Fischer–Griess monster group

This article examines the relationship between gender, class and unpaid care for children and elderly household members across twenty-five countries. Using the microdata files of the 2015–2017 Luxembourg Income Study, we demonstrate that household income quintile shapes the relationship between resident caregiving and a) women’s diminished share of household income and b) the associated “wage penalty” women experience in paid employment, examining dual-headed heterosexual households and grouping countries at varying levels of GDP per capita. Our analyses demonstrate that both eldercare and chi

Abstract:
We review the emergence of hypergeometric structures (of F4 Appell functions) from the conformal Ward identities (CWIs) in conformal field theories (CFTs) in dimensions d > 2. We illustrate the case of scalar 3- and 4-point functions. 3-point functions are associated to hypergeometric systems with four independent solutions. For symmetric correlators, they can be expressed in terms of a single 3K integral—functions of quadratic ratios of momenta—which is a parametric integral of three modified Bessel K functions. In the case of scalar 4-point functions, by requiring the correlator to be con

Abstract:
Abstract Context.—Giant cell glioblastoma multiforme (GCGBM) and pleomorphic xanthoastrocytoma (PXA) are clinically, radiographically, and histologically distinct tumors of the central nervous system. However, they share features of gross circumscription, reticulin deposition, lymphocytic infiltrates, and prominent populations of tumor giant cells. Neuronal antigens have been detected in the neoplastic cells of PXAs, but to our knowledge have not been studied previously in GCGBMs. While TP53 is mutated in most GCGBMs, a feature usually paralleled by strong immunostaining of the protein, the ex
