Hospital acquisition by another hospital or hospital system was associated with modestly worse patient experiences and no significant changes in readmission or mortality rates, and effects on process measures of quality were inconclusive.

This study examines the relationship between economic policy uncertainty and mergers and acquisitions (M&As) in China. Using all listed Chinese companies on the Shanghai and Shenzhen Stock Exchanges as well as 4188 ​M&A deals from the period of 2001–2018, we show that Chinese firms are more likely to make acquisitions during periods of high economic policy uncertainty, which contradicts the behavior of US firms. We further show that state-owned enterprises (SOEs) are less likely than non-SOEs to make acquisitions during periods of high economic policy uncertainty. SOEs are less likely ...

In recent years, heavy pollution enterprises often adopt green merger and acquisition (GMA) strategy to obtain green technology and resources, so as to realize the transformation and upgrading of pollution industry. Can GMA increase the environmental protection investment (EPI) and promote the green development of enterprises? The important marginal contribution of this paper is to explore the impact of GMA on EPI of heavy pollution listed companies, and compare the impact of different types of GMA on EPI. In this paper, PSM-DID method and nonlinear DID method are used for empirical analysis. ...

The integration of Environmental, Social, and Governance (ESG) considerations in corporate mergers and acquisitions (M&A) has gained significant traction as companies recognize the strategic value of sustainability in dealmaking. This paper explores how ESG factors can be incorporated into M&A strategies to drive value creation, meet regulatory requirements, and enhance corporate reputation. Leveraging improved data and tracking methods, the study highlights the increasing importance of ESG in M&A, presenting a comprehensive analysis of environmental, social, and governance factors...

Abstract This study explores the effect of environmental, social, and governance (ESG) performance on market value and performance in the context of mergers and acquisitions. We examine whether acquisition of targets with better ESG performance can help acquirers to increase their own ESG performance and whether the market values the increased ESG performance positively. Moreover, we explore whether the acquisition of targets with better ESG performance affects the market value of acquirers. For this study, we utilize a sample of 100 European mergers and acquisitions between 2003 and 2017, for...

In the past decade, synthetic chemists have discovered the outstanding generality and potential of visible-light-driven photoredox catalysis, which converts visible light into chemical energy, realizing numerous transformations of small molecules. The current state-of-the-art strategy in photoredox catalysis, combining photoredox and transition-metal catalysis, has received considerable attention in organometallic chemistry. In parallel with the rapid development of nickel/photoredox and copper/photoredox catalysis, cobalt/photoredox catalysis has emerged as a distinct new option in this area....

Abstract Binary neutron star mergers observations are a unique way to constrain fundamental physics and astrophysics at the extreme. The interpretation of gravitational-wave events and their electromagnetic counterparts crucially relies on general-relativistic models of the merger remnants. Quantitative models can be obtained only by means of numerical relativity simulations in $$3+1$$ 3 + 1 dimensions including detailed input physics for the nuclear matter, electromagnetic and weak interactions. This review summarizes the current understanding of merger remnants focusing on some of the aspect...

ABSTRACT Accretion discs around supermassive black holes are promising sites for stellar mass black hole mergers detectable with LIGO. Here we present the results of Monte Carlo simulations of black hole mergers within 1-d AGN disc models. For the spin distribution in the disc bulk, key findings are: (1) The distribution of χeff is naturally centred around $\tilde{\chi }_{\rm eff} \approx 0.0$, (2) the width of the χeff distribution is narrow for low natal spins. For the mass distribution in the disc bulk, key findings are: (3) mass ratios $\tilde{q} \sim 0.5\!-\!0.7$, (4) the maximum merger m...

Mergers of binaries consisting of two neutron stars, or a black hole and a\nneutron star, offer a unique opportunity to study a range of physical and\nastrophysical processes using two different and almost orthogonal probes -\ngravitational waves (GW) and electromagnetic (EM) emission. The GW signal\nprobes the binary and the physical processes that take place during the last\nstages of the merger, while the EM emission provides clues to the material that\nis thrown out following the merger. The accurate localization, which only the\nEM emission can provide, also indicates the astrophysical se...

This paper argues that incumbent firms may acquire innovative targets solely to discontinue the target’s innovation projects and preempt future competition. We call such acquisitions “killer acquisitions.” We develop a model illustrating this phenomenon. Using pharmaceutical industry data, we show that acquired drug projects are less likely to be developed when they overlap with the acquirer’s existing product portfolio, especially when the acquirer’s market power is large because of weak competition or distant patent expiration. Conservative estimates indicate that 5.3%–7.4% of acquisitions i...

The recently discovered gravitational wave sources GW190521 and GW190814 have shown evidence of BH mergers with masses and spins outside of the range expected from isolated stellar evolution. These merging objects could have undergone previous mergers. Such hierarchical mergers are predicted to be frequent in active galactic nuclei (AGNs) disks, where binaries form and evolve efficiently by dynamical interactions and gaseous dissipation. Here we compare the properties of these observed events to the theoretical models of mergers in AGN disks, which are obtained by performing one-dimensional N-...

In this article, we assess the genealogical validity of West‑Coastal Bantu (WCB) as a major subclade of the Bantu family by means of the Comparative Method. Based on a comparative dataset of 66 different cognate series, we demonstrate that languages previously classified as WCB according to lexicon‑based quantitative methods share at least one common phonological innovation: the phonemic merger of the Proto‑Bantu velar stops *g and *k due to the devoicing of *g when not preceded by a nasal. We show that the velar merger is a unique phonological innovation distinguishing WCB from other Bantu ph...

With the first observation of a binary neutron star merger through gravitational waves and light, GW170817, compact binary mergers have now taken the center stage in nuclear astrophysics. They are thought to be one of the main astrophysical sites of production of r-process elements, and merger observations have become a fundamental tool to constrain the properties of matter. Here, we review our current understanding of the dynamics of neutron star mergers in general and of GW170817 in particular. We discuss the physical processes governing the inspiral, merger, and postmerger evolution, and we...

This Review details and contextualizes the advancements in molecule construction brought forth by metallaphotocatalysis and identifies novel activation modes entirely complementary to traditional catalytic platforms.

Natural sign languages of deaf communities are acquired on the same time scale as that of spoken languages if children have access to fluent signers providing input from birth. Infants are sensitive to linguistic information provided visually, and early milestones show many parallels. The modality may affect various areas of language acquisition; such effects include the form of signs (sign phonology), the potential advantage presented by visual iconicity, and the use of spatial locations to represent referents, locations, and movement events. Unfortunately, the vast majority of deaf children ...

Abstract The astrophysical origin of gravitational wave transients is a timely open question in the wake of discoveries by the Laser Interferometer Gravitational-Wave Observatory (LIGO)/Virgo. In active galactic nuclei (AGNs), binaries form and evolve efficiently by interaction with a dense population of stars and the gaseous AGN disk. Previous studies have shown that stellar-mass black hole (BH) mergers in such environments can explain the merger rate and the number of suspected hierarchical mergers observed by LIGO/Virgo. The binary eccentricity distribution can provide further information t...
