Globalizing the Boardroom - The Effects of Foreign Directors on Corporate Governance and Firm Performance

Abstract: We examine the benefits and costs associated with foreign independent directors (FIDs) at U.S. corporations. We find that firms with FIDs make better cross-border acquisitions when the targets are from the home regions of FIDs. However, FIDs also display poor board meeting attendance records, and firms with FIDs are more prone to commit intentional financial misreporting and overpay their CEOs and have lower CEO turnover sensitivity to performance. Finally, firms with FIDs are associated with significantly poorer performance, especially as their business presence in the FID’s home region becomes less important.

Severe acute respiratory syndrome (SARS) in Hong Kong in 2003: stress and psychological impact among frontline healthcare workers

Abstract: Background The outbreak of severe acute respiratory syndrome (SARS) posed an unprecedented threat and a great challenge to health professionals in Hong Kong The study reported here aimed at investigating the origin of stress and psychological morbidity among frontline healthcare workers in response to this catastropheMethod Self-administered questionnaires were sent to frontline healthcare workers in three hospitals The General Health Questionnaire was used to identify psychological distress Sociodemographic and stress variables were entered into a logistic regression analysis to find out the variables associated with psychological morbidityResults The response rate was 40% Sixty-eight per cent of participants reported a high level of stress About 57% were found to have experienced psychological distress The healthcare workers' psychological morbidity was best understood by the perceptions of personal vulnerability, stress and support in the workplaceConclusion These findings shed light on the need for hospital administrators to be aware of the extent and sources of stress and psychological distress among frontline healthcare workers during disease outbreak

Cooperative Output Regulation of Linear Multi-Agent Systems

Abstract: In this technical note, we consider the cooperative output regulation of linear multi-agent systems. The overall system consists of two groups of subsystems. While the first group of subsystems can access the exogenous signal, the second cannot. As a result, the problem cannot be solved by the decentralized approach. By devising a distributed observer, we can solve the problem by a dynamic full information distributed control scheme. The problem can also be viewed as a generalization of some results of the leader-following consensus problem of multi-agent systems.

Covid-19 and the digestive system.

Abstract: The novel coronavirus disease is currently causing a major pandemic. It is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a member of the Betacoronavirus genus that also includes the SARS-CoV and Middle East respiratory syndrome coronavirus. While patients typically present with fever and a respiratory illness, some patients also report gastrointestinal symptoms such as diarrhea, vomiting, and abdominal pain. Studies have identified the SARS-CoV-2 RNA in stool specimens of infected patients, and its viral receptor angiotensin converting enzyme 2 was found to be highly expressed in gastrointestinal epithelial cells. These suggest that SARS-CoV-2 can actively infect and replicate in the gastrointestinal tract. This has important implications to the disease management, transmission, and infection control. In this article, we review the important gastrointestinal aspects of the disease.

Care for Critically Ill Patients With COVID-19.

Abstract: Recommendations Infection Control • For health care workers who are performing aerosol-generating procedures on patients with COVID-19, the COVID-19 Treatment Guidelines Panel (the Panel) recommends using an N95 respirator (or equivalent or higher-level respirator) rather than surgical masks, in addition to other personal protective equipment (PPE) (i.e., gloves, gown, and eye protection such as a face shield or safety goggles) (AIII). • The Panel recommends minimizing the use of aerosol-generating procedures on intensive care unit patients with COVID-19 and carrying out any necessary aerosol-generating procedures in a negative-pressure room, also known as an airborne infection isolation room, when available (AIII). • For health care workers who are providing usual care for nonventilated patients with COVID-19, the Panel recommends using an N95 respirator (or equivalent or higher-level respirator) or a surgical mask in addition to other PPE (i.e., gloves, gown, and eye protection such as a face shield or safety goggles) (AII). • For health care workers who are performing non-aerosol-generating procedures on patients with COVID-19 who are on closed-circuit mechanical ventilation, the Panel recommends using an N95 respirator (or equivalent or higher-level respirator) in addition to other PPE (i.e., gloves, gown, and eye protection such as a face shield or safety goggles) because ventilator circuits may become disrupted unexpectedly (BIII). • The Panel recommends that endotracheal intubation in patients with COVID-19 be performed by health care providers with extensive airway management experience, if possible (AIII). • The Panel recommends that intubation be performed using video laryngoscopy, if possible (CIII).
