In June 2015, an outbreak of salmonellosis occurred among people who had eaten at a restaurant in Darwin, Northern Territory over 2 consecutive nights. We conducted a retrospective cohort study of diners who ate at the restaurant on 19 and 20 June 2015. Diners were telephoned and a questionnaire recorded symptoms and menu items consumed. An outbreak case was defined as anyone with laboratory co...

OBJECTIVES This study aimed to characterize the prevalence of antibiotic resistance in Escherichia coli isolates from the fecal samples of fishery workers who work in fish farms and often use antibiotics for the feeding fishes. METHODS Seventy-three E. coli strains isolated from the fecal samples of fishery workers and 180 isolates from a control group of restaurant workers were tested for an...

This study examined whether restaurant characteristics are associated with critical violations identified during restaurant inspections. Using multiple years of data, we also examined changes in critical violation patterns over time. Data from all restaurant inspections in Jefferson County, Alabama between the years 2008–2010 were analyzed. The results of a total of 5,488 inspections were exami...

Consumption of restaurant food and beverage products high in fat, sugar and sodium contribute to obesity and non-communicable diseases. We evaluated restaurant-sector progress to promote healthy food environments for Americans. We conducted a desk review of seven electronic databases (January 2006-January 2017) to examine restaurant strategies used to promote healthful options in the United Sta...

In this paper, an example of pervasive computing in restaurant, a wireless web-based ordering system is presented. By using mobile devices such as Personal Digital Assistants (PDA) and WebPad, customers can get many benefits when making orders in restaurants. With this system, customers get faster and better services, restaurant staff cooperate more efficiently with less working mistakes, and e...

In the past decades, people have gained a wide range of options as the availability of information expands. To help them make decisions, recommendation systems play an important role in all kinds of aspects, e.g. news, books, movies and so on. In this project, we built a restaurant recommendation system by incorporating the power of social networks and local business review sites. To make accur...

We begin with a proof of the ESF. This is essentially Kingman’s proof (understanding ESF was the main motivation for his introduction of the coalescent). Proof: Let Π be the partition generated by the infinite-alleles model on n sample. We call each set in Π a cluster. Assume there are k clusters. Looking backwards in time, to obtain Π it must be that each cluster undergoes a sequence of coales...

We develop the distance dependent Chinese restaurant process, a flexible class of distributions over partitions that allows for dependencies between the elements. This class can be used to model many kinds of dependencies between data in infinite clustering models, including dependencies arising from time, space, and network connectivity. We examine the properties of the distance dependent CRP,...
