Automated discovery and extraction of biological relations from online documents, particularly MEDLINE texts, has become essential and urgent because such literature data are accumulated in a tremendous growth. In this paper, we present an ontology-based framework of biological relation extraction system. This framework is unified and able to extract several kinds of relations such as gene-dise...

Supervised relation extraction uses a pre-defined schema of relation types (such as born-in or employed-by). This approach requires labeling textual relations, a time-consuming and difficult process. This has led to significant interest in distantly-supervised learning. Here one aligns existing database records with the sentences in which these records have been “rendered”, and from this labeli...

In this paper, we present a genetic algorithm approach that considers the single machine scheduling problem. There are n jobs, in which each job j ( 1 2 j n = , ,..., ) has a normal processing time j p , a due date j d , earliness penalty j α , and tardiness penalty j β . The objective is to find the sequence of jobs that minimizes the weighted sum of earliness and tardiness penalty costs, with...

Over the past 20 years, there has been a dramatic increase in the share of executive compensation paid through stock options. We examine the extent to which tax policy has inuenced the composition of executive compensation, and discuss the implications of rising stock-based pay for tax policy. We begin by describing the tax rules for executive pay in detail and analyzing how changes in various...

The current study examined the role of co-worker support for safety within the broader context of perceived safety climate predicting safety behavior and outcomes for the mobile worker population of team truck drivers. Namely, the mediation, moderation, and incremental direct effects of co-worker support for safety were tested. The current study examined 366 team truck drivers from a single tru...

We analyze the effect of committee formation on how corporate boards perform two main functions: setting CEO pay and overseeing the financial reporting process. The use of performance-based pay schemes induces the CEO to manipulate earnings, which leads to an increased need for board oversight. If the whole board is responsible for both functions, it is inclined to provide the CEO with a compen...

In response to the corporate scandals in 2001-2002, the major U.S. exchanges came up with new regulations which are intended to enhance board oversight. We use this regulation event to shed light on the effect of board oversight on CEO compensation. We find that firms that were not complying with these regulations decreased their CEO compensation by between 20%-25% upon compliance, compared to ...

course, arising out of the Workmen's Compensation Act, but sometimes under common law as well ; and therefore a review of those decisions which have helped to define what an accident is may not be out of place at a medical meeting. It is curious that neither of the Workmen's Compensation Acts contained this definition, so that the meaning of the term has tended to vary case by case. Prior to th...
