Integrated Navigation System: Not a Sum of Its Parts

By: Capt. Joseph F. Ryan

Instead, the trend is toward integration, data fusion and synergy. One example of this are new Performance Standards being considered by IMO to achieve a "harmonized" presentation of all navigation-related information on the display of an integrated navigation system (INS).

An Easy Assist for an Overlooked but Tough Group

By: Dr. Kenneth E. Lehrer

There are few groups more reliable than the United States military. One could change all of their mottoes to "Again and again - no questions asked." Those who have served in the military have done so at a solid financial cost. Despite this, the years of the 1950s, 1960s and even into the 1970s were periods with high savings rates, rates that today appear almost unachievable. How did they save so much, seek to enjoy life so fully and raise another generation, the Baby Boomers?

Outbreaks Where Food Workers Have Been Implicated in the Spread of Foodborne Disease. Part 5. Sources of Contamination and Pathogen Excretion from Infected Persons

By: Dr. Ewen Todd

In this article, the fifth in a series reviewing the role of food workers in foodborne outbreaks, background information on the routes of infection for food workers is considered. Contamination most frequently occurs via the fecal-oral route, when pathogens are present in the feces of ill, convalescent, or otherwise colonized persons. It is difficult for managers of food operations to identify food workers who may be excreting pathogens, even when these workers report their illnesses, because workers can shed pathogens during the prodrome phase of illness or can be long-term excretors or asymptomatic carriers.
