Research Summary : This article exploits a natural experiment to estimate the causal effect of political uncertainty on bargaining outcomes in cross‐border acquisitions. We argue that alters relative power between acquiring versus target firms. The host country's makes returns acquisitions more unpredictable. Accordingly, foreign acquirers demand compensation for such negotiations, otherwise they will not consider their profitable. Thus, when is high country, ceteris paribus, have greater...
Hepatitis B virus (HBV) infection is the most common cause of liver disease in endemic areas such as South Korea. After HBV vaccination, hepatitis surface antibody (HBsAb) titers gradually decrease. Trends HBsAb have not been evaluated among children Korea over past decade. We screened 6155 patients (aged 7 months to 17 years) who underwent antigen/antibody testing at Chung-Ang University Hospital from May 2012 April 2015. Titer criteria were defined follows: positive, titer ≥100 IU/L;...
Abstract Consistent with the notion that dividends are very sticky, Daniel, Denis, and Naveen ( ) report evidence firms manage earnings upward when pre‐managed expected to fall short of dividend payments. However, we find this is not robust controlling for firms' tendency avoid reporting declines; only high leverage exhibit a statistically weak close deficits relative dividends. We further decision cut depends on whether reported past dividends, but management eliminates shortfall in...
The novel coronavirus disease 2019 (COVID-19) spread rapidly worldwide. Nursing home (NH) residents are the most vulnerable high-risk population to infection. Professional registered nurses’ (RNs’) infection control is irreplaceable. We used a secondary data analysis method using government's senior citizen welfare department large set about all NHs (N = 3,389) across Korea between January 20 and October 20, 2020. Bed size positively associated with mortality rate (No. of COVID-19 resident...
Abstract Introduction Children's rare lung diseases are a heterogeneous group of with significant morbidity and mortality. There is very limited information on the incidence prevalence children's in Asia. We investigated nationwide incidence, prevalence, pattern medical service utilization Korea. Methods studied patients who were diagnosed coded per International Statistical Classification Diseases Related Health Problems, 10th Edition registered national database confirmed patients. Data...
This paper examines the effects of political uncertainty surrounding national elections on cross-border mergers and acquisitions activity. Using a sample completed among 43 countries announced during 1990-2011, I find that volume between two significantly declines when there is forthcoming election in target country. result suggests regarding future government policy an important determinant acquisition In addition, industry characteristics play role explaining pattern amid increasing...
Cardiac tamponade (CT) is a rare but potentially lethal complication associated with central venous catheters (CVCs). We present 6-year-old boy who developed CT after CVC insertion in the right internal jugular vein, its tip inferior vena cava. Initially, he was hospitalized to tertiary hospital presumptive diagnoses of pneumonia and left ankle cellulitis. Three days placement, CT, manifesting as recurrent episodes hypotension bradycardia. Once bedside echocardiography showed...
Background: Early childhood obesity is highly associated with in adolescents and adults. However, studies on specific eating behaviors that have a decisive effect early (aged 3–5 years) are scarce. We hypothesized critical risk factors leading to at ages of years may be different. To confirm this hypothesis, we conducted study the related preschool children. Methods: Using National Health Screening Program for Infants Children (NHSPIC) Korea’s general population cohort, found trends...
Background Extracorporeal membrane oxygenation (ECMO) is a critical intervention for pediatric patients with cardiac-related medical indications. However, data on its outcomes and associated risk factors, particularly in Korea, are limited. This study aimed to evaluate these identify predictors of mortality. Methods A multicenter retrospective was conducted 152 who underwent ECMO conditions between 2012 2021. Data patient demographics, clinical features, laboratory findings, were collected...
We construct a measure of firm’s exposure to labor market agglomeration in the locality—a we label LEO—and examine whether such is key factor firms’ employee-related policies. find that when LEO high, firms grant more broad-based stock options, provide employee-friendly work environment, and maintain financial flexibility. This relation present only for high-skilled workers stronger investing R&D. Our results show strategically adopt policies retain employees who face better local...
We study the effects of multi-layered governance on firm risk by focusing interaction two types career concerns. Two Delaware court decisions, validation poison pill defenses (the Unitrin decision) implemented staggered boards Wallace decision), reduced takeover-related CEO age influences response firms to these shocks. Older CEOs in newly insulated reduce risk, while their younger counterparts increase risk. Ex-post, differential behavior among young appears be rewarded with abnormally...
Consistent with the notion that dividends are very sticky, Daniel, Denis, and Naveen (2008) report evidence firms manage earnings upward when pre-managed expected to fall short of dividend payments. However, we find this is not robust controlling for firms’ tendency avoid reporting declines; only high leverage exhibit a statistically weak close deficits relative dividends. We further decision cut depends on whether reported past dividends, but management eliminates shortfall in Overall, our...
The fast pacing of cross-border acquisitions (CBAs) can be critical to a firm’s competitiveness. But the antecedents ability quickly execute serial CBAs and thus build strategic momentum have been disregarded in international strategy literature. We focus on role CEO cognition argue that firms are better able compress time between deals target country when has more acquisition experience focal firm this shares similar cognitive frame with due cultural ancestry links. Using sample by 348 US...
Bronchopulmonary dysplasia (BPD) and pulmonary hypertension (PH) are potentially fatal complications in prematurely born infants. Extracorporeal membrane oxygenation (ECMO) may be a life-saving option for managing infants with BPD PH. We present 2 patients who were successfully weaned off mechanical ventilators (MVs) through the application of ECMO. The transferred to our institution after receiving MV care 8 10 months, respectively, able remove from MVs period ECMO-mediated lung rest....

Durable goods have larger price elasticities of demand than non-durable and services. This presents a challenge to durable producers because it negatively affects their ability adjust product prices when input costs increase. We find that firms with more output cash balances marginal value cash, lower propensity pay dividends dividend payouts, financial leverage. These effects are accentuated in less concentrated industries. Consistent the desire build flexibility, we markups for decline,...
