Algebraic effects combined with effect handlers have emerged as compelling, modular abstraction for modelling and controlling computational effects. By separating the effect signatures from their implementation, algebraic effects afford a high degree of modularity as programmers can describe effectful computations independently of their concrete interpretation. We present a compiler for the fun...

OBJECTIVE Flight baggage handlers sort and load luggage to airplanes. This study aimed at investigating associations between psychosocial exposures and low back and shoulder musculoskeletal disorders (MSDs) among Swedish flight baggage handlers. METHODS A questionnaire addressing MSDs (Standardized Nordic Questionnaire) and psychosocial factors (Copenhagen Psychosocial Questionnaire, COPSOQ) ...

his study aimed to determine the health status of food handlers working in the cafeterias of educational institutions, and those working in the restaurants of a tourist area in Sai-Yok District, Kanchanaburi Province, Thailand. A total of 273 stool samples were collected: 29.3% (80/273) from food handlers in the educational institutions, and 70.7% (193/273) from food handlers in touristarea res...

Detection and elimination of Byzantine faults in the Web services environment by applying the features of SOAP handlers is the principle objective of this work. The Web services may sometimes be infused with suspicious modules intentionally for them to behave in an abnormal manner. By introducing faulty aspects into the service deployment on the fly makes the Web service to generate Byzantine f...

BACKGROUND/PURPOSE Intestinal parasitic and bacterial infections constitute a major health issue in developing countries. The present study investigates and assesses infection rates among food handlers with intestinal parasites and microbial agents in luxurious hotels in the Dead Sea area of Jordan. METHODS A total of 901 stool samples were collected from food handlers (35 females and 866 mal...

Exceptions are an indispensable part of modern programming languages. They are, however, handled poorly, especially by higherorder languages such as Standard ML and Haskell: in both languages a well-typed program can unexpectedly fail due to an uncaught exception. In this paper, we propose a technique for type-safe exception handling. Our approach relies on representing exceptions as sums and a...

Clinical waste disposal carries with it a risk of serious and possibly life-threatening infection. Combining confidential questionnaires and structured interviews with discrete observation, the attitudes and approach to safe handling of bulk clinical wastes by staff in a specialist waste treatment facility were assessed. With particular attention to glove use and hand hygiene, observations were...
