Her area of concentration is international relations , with subspecialties in international political economy and the relationship between democracies and international disputes . In another type of insourcing , an enterprise purchases new equipment or trains existing personnel to perform tasks that would otherwise have been outsourced . For example , security-related tasks that involve circumventing security systems , encryption research , or reverse engineering software would be illegal . The program has long filename support , file version management , archive merging , password protection , data damage protection , a digital signature option , recurse directory support , ANSI escape sequence display handler , configurable command options , handling of up to 99 volumes , ability to store up to 250 backups per archive , ability to work with duplicate filenames within archives , and archives that span diskettes . Take a walking tour of the town 's squares and narrow passages , which lead into the Grote Markt , where guildhalls once bustled with Antwerp 's 17th-century merchants and tradesmen . Sonenshein is the principal investigator for the research team that includes Dr. Saul Tzipori , professor of biomedical sciences and director of infectious diseases at the Cummings School of Veterinary Medicine at Tufts , and Dr. Miguel Stadecker , professor of pathology . The work could make inexpensive , needle-free , heat-resistant medications widely available in developing nations where poverty , the lack of trained personnel to give injections , and inconsistent refrigeration means some 27 million children annually are not protected against common childhood diseases . This type of insourcing may require considerable training of existing personnel for the tasks . With the grant , Tufts established a Microbiology Research Unit in the new nationwide Food and Waterborne Disease Integrated Research Network , with Tzipori , Distinguished Professor of Microbiology and Infectious Diseases and Agnes Varis University Chair in Science and Society , leading the initiative . ( OSAF ) Here 's more information about Chandler , which is intended to be an open source personal information manager for e-mail , calendars , contacts , tasks and general information management , as well as a platform for developing information-management applications . The Cummings School of Veterinary Medicine has received a $ 15 million grant from the National Institutes of Health to build a state-of-the-art regional biosafety laboratory that will advance research into food - and water-borne diseases that threaten public health . Antigens are the proteins that stimulate the immune system to develop resistance to specific diseases .
