The process of "transitioning" to adulthood for youth with disabilities has long been recognized to be an important but understudied public policy concern. This paper evaluates the labor market effects of Virginia’s school-to-work vocational evaluation program, PERT. Using a unique panel data set containing more than a decade of employment and service provision, we provide the first-ever assess...

Our modeling of PERT is composed of three parts: window adjustment, RED emulation, and queuing behavior. We start with the window dynamics. Similar to [7], we consider a single-link scenario and assume the forward propagation delay from the source to the router is negligible and thus the round-trip time R(t) measured by the end-user at time t is composed of backward propagation delay Tp and que...

Exocrine pancreatic insufficiency (EPI), an important cause of maldigestion and malabsorption, results from primary pancreatic diseases or secondarily impaired exocrine pancreatic function. Besides cystic fibrosis and chronic pancreatitis, the most common etiologies of EPI, other causes of EPI include unresectable pancreatic cancer, metabolic diseases (diabetes); impaired hormonal stimulation o...

Pancreatic exocrine insufficiency (PEI) frequently occurs secondary to exocrine pancreatic disease (e.g. chronic pancreatitis, cystic fibrosis, cancer) or pancreatic/gastrointestinal surgery, resulting in the maldigestion of nutrients and consequently malnutrition. Pancreatic enzyme replacement therapy (PERT) is the cornerstone of PEI management. Despite its clinical relevance, the diagnosis of...

The announcement of the 1978 Lasker Award for Basic Medical Research has created two controversies. No one argues with the choice of the three winners-Solomon H. Snyder (Johns Hopkins University), John Hughes (Imperial College of Science and Technology. London), and Hans Kosterlitz (University of Aberdeen) —who were honored for the discovery of opiate receptors and enkephalins, opiate-like subs...
