This document treats the crosstalk between parallel conductors. The conductors can represent either conductors in a multiconductor cable or traces on a printed circuit board (PCB). An analysis method based on a lumped circuit equivalent for the problem as well as a method to calculate the per unit length parameters are presented. The computed results are validated by comparison with measurement...

In the wake of meltdowns at WorldCom, Tyco, and Enron, enormous attention has been focused on the companies' boards. It seems inconceivable that business disasters of such magnitude could happen without gross or even criminal negligence on the part of board members. And yet a close examination of those boards reveals no broad pattern of incompetence or corruption. In fact, they followed most of...

laboratory. The highlight, in my opinion, is the space devoted to clinical correlations (stethoscope icon), which helps the student to learn histology through the perspective of pathology. Both authors are professors of pathology, and the incorporation of the clinical sections demonstrates their understanding the need and desire of most students to learn histology. In fact, I would recommend th...

We provide a message board model for collaborative systems, and propose an architecture and protocol for securing collaborative applications over message boards. The proposed architecture employs only efficient symmetric cryptographic principles, and low complexity trust modules with each participant. The trust modules are used to protect group secrets and reduce susceptibility to denial of ser...

Many online financial message boards exist where users can discuss the latest information about their favorite stocks. However, the sheer number of postings and the high level of noise in these postings present a significant challenge to message board users seeking to extract recommendations on whether to buy or sell a stock. Earlier attempts to extract sentiment and information from these boar...

A growing body of ethics research investigates gender diversity and governance on corporate boards, at individual and firm levels, in single country studies. In this study, we explore the environmental context of female representation on corporate boards of directors, using data from forty-three countries. We suggest that women's representation on corporate boards may be shaped by the larger en...

Currently, a director is classified as independent if he or she has neither financial nor familial ties to the CEO or to the firm. We add another dimension: social ties. Using a unique data set, we find that 87% of boards are conventionally independent but that only 62% are conventionally and socially independent. Furthermore, firms whose boards are conventionally and socially independent award...

Because of the increasing interest in and use of complementary and alternative therapies in medical practices (CAM), state medical boards have a responsibility to assure that licensees utilize CAM in a manner consistent with safe and responsible medicine. On behalf of the Federation of State Medical Boards and its continued commitment to assist state medical boards in protecting the public and ...

OBJECTIVES Hospital boards are legally responsible for safe healthcare. They need tools to assist them in their task of governing patient safety. Almost every Dutch hospital performs internal audits, but the effectiveness of these audits for hospital governance has never been evaluated. The aim of this study is to evaluate the organisation of internal audits and their effectiveness for hospital...

BACKGROUND Decentralization through the establishment of hospital governing boards has been touted as an effective way to improve the quality and efficiency of hospitals in low-income countries. Although several studies have examined the process of decentralization, few have quantitatively assessed the implementation of hospital governing boards and their impact on hospital performance. Therefo...
