Expanding Horizons with Chameleon: Team Missouri\u27s Innovative Home Automation System

Team Missouri\u27s 2009 Solar Decathlon entry featured a revolutionary home automation system, Chameleon, promoting both convenience and energy savings. This was accomplished using the typical controls of a convenience based automation system, while maintaining user set points, such as a home\u27s ambient temperature, in the most energy efficient manner. Environmental features of the system include controls for home heating, ventilation and air conditioning, lighting, windows, shades, appliances, indoor air quality, as well as indoor and outdoor irrigation. Further analysis and refinement to the prototype system displayed at the competition is also presented in this paper

Some simple rules for estimating reproduction numbers in the presence of reservoir exposure or imported cases

For many diseases, the basic reproduction number () is a threshold parameter for disease extinction or survival in isolated populations. However no human population is fully isolated from other human or animal populations. We use compartmental models to derive simple rules for the basic reproduction number in populations where an endemic disease is sustained by a combination of local transmission within the population and exposure from some other source: either a reservoir exposure or imported cases. We introduce the idea of a reservoir-driven or importation-driven disease: diseases that would become extinct in the population of interest without reservoir exposure or imported cases (since ), but nevertheless may be sufficiently transmissible that many or most infections are acquired from humans in that population. We show that in the simplest case, if and only if the proportion of infections acquired from the external source exceeds the disease prevalence and explore how population heterogeneity and the interactions of multiple strains affect this rule. We apply these rules in two case studies of Clostridium difficile infection and colonisation: C. difficile in the hospital setting accounting for imported cases, and C. difficile in the general human population accounting for exposure to animal reservoirs. We demonstrate that even the hospital-adapted, highly-transmissible NAP1/RT027 strain of C. difficile had a reproduction number <1 in a landmark study of hospitalised patients and therefore was sustained by colonised and infected admissions to the study hospital. We argue that C. difficile should be considered reservoir-driven if as little as 13.0% of transmission can be attributed to animal reservoirsAustralian Government Research Training Program Scholarshi

Experiential Learning in a Management Information Systems Course: Simulating IT Consulting and CRM System Procurement

Educating management students in technology-based disciplines can be enhanced through experiential team projects simulating the activities employees perform in actual technology jobs. This paper describes an experiential team project the authors use in the Management Information Systems course at Boston College. The project was developed jointly by Boston College faculty and consultants from the Boston office of a major consulting firm. The project involves student teams playing the roles of IT consultants who must compete against one another to win a consulting engagement at an imaginary company. The company\u27s business situation is communicated to students through a case study written in the format of a Request For Proposal (RFP) informing information technology (IT) vendors that the company is interested in procuring a Customer Relationship Management (CRM) system. Each student team develops a consulting proposal responding to the RFP and presents the proposal to company managers. The activities involved in identifying the company\u27s business needs, developing a proposal, and determining which team wins the contract are simulated through phone calls and live meetings with company managers, who are role-played by consulting firm employees. These real-life business interactions expose students to the ever changing nature of IT, motivate them to improve their technical understanding, and challenge them to improve their communication skills through written deliverables and live business presentations. Student buy-in and response to the project is strong and immediate since they find themselves challenged by complex, relevant business issues

The campylobacteriosis conundrum - examining the incidence of infection with Campylobacter sp. in Australia, 1998 - 2013

Campylobacter sp. are a globally significant cause of gastroenteritis. Although rates of infection in Australia are among the highest in the industrialized world, studies describing campylobacteriosis incidence in Australia are lacking. Using national disease notification data between 1998 and 2013 we examined Campylobacter infections by gender, age group, season and state and territory. Negative binomial regression was used to estimate incidence rate ratios (IRRs), including trends by age group over time, with post-estimation commands used to obtain adjusted incidence rates. The incidence rate for males was significantly higher than for females [IRR 1·20, 95% confidence interval (CI) 1·18–1·21], while a distinct seasonality was demonstrated with higher rates in both spring (IRR 1·18, 95% CI 1·16–1·20) and summer (IRR 1·17, 95% CI 1·16–1·19). Examination of trends in age-specific incidence over time showed declines in incidence in those aged <40 years combined with contemporaneous increases in older age groups, notably those aged 70–79 years (IRR 1998–2013: 1·75, 95% CI 1·63–1·88). While crude rates continue to be highest in children, our findings suggest the age structure for campylobacteriosis in Australia is changing, carrying significant public health implications for older AustraliansThe data were collected as part of the Australian Research Council Linkage Project (LP110200431) ‘Identifying and controlling the source of Campylobacter and Salmonella in Australia’.

The Chameleon Team

Project Leaders: Barbara Buffaloe, Katie Grantham Lough, Luke Wesselschmidt, Jacqueline McDermott-Kelty, Rashad Abdul-Majid, Bryan Glass, Heather BensonProposal for the 2008 project: "The Chameleon Team." The University of Missouri?Columbia (MU) and Missouri University of Science and Technology (S&T) have teamed to develop an exciting energy conservation product. The Chameleon project will produce an artificially intelligent residential energy management system designed to blend into its environment. Upon successful completion of this project, the Chameleon home automation system will enable the average homeowner to conserve energy and save money by simply having the system installed in their home and not changing any of their daily activities. This total budget of the design, development, and implementation of Chameleon�s prototypes is well over the budget for this funding opportunity, this proposal will focus on the educational partnerships required to develop the user interface for the system. This multi?university undergraduate student project incorporates engineering, architectural studies, and interior design students to develop a seamlessly integrated and highly functioning home automation system that requires no technical skills to operate. The underlying technology that enables the project is the IT capabilities of both universities which will enable weekly video?conference design meetings as well as internet accessible energy monitoring data available in real �time. In addition, students on both campuses utilize computer programs specific to their disciplines and learn program associated with other disciplines due to the multidisciplinary efforts required. For example, S&T students use the computer program, Maui Solar, to estimate the size and placement of solar panels for home energy production. MU students often suggest solar energy production on their concept designs but do not know the details of how and where to place the modules. Working together with the computer program, students from both campuses are learning the importance of each disciplines� core software programs. The Chameleon team�s proposal for the Interdisciplinary Innovation Fund meets the requirement from the MU Information Technology Committee. The student led team is working to make the UM system a leader in energy conservation through the use of cutting edge technology and multidisciplinary design efforts that make the technology available to the average homeowner.MU Interdisciplinary Innovations Fun

A population-based longitudinal study of Clostridium difficile infection-related hospitalization in mid-age and older Australians

Clostridium difficile is the principal cause of infectious diarrhoea in hospitalized patients. We investigated the incidence and risk factors for hospitalization due to C. difficile infection (CDI) in older Australians. We linked data from a population-based prospective cohort study (the 45 and Up Study) of 266 922 adults aged ⩾45 years recruited in New South Wales, Australia to hospitalization and death records for 2006–2012. We estimated the incidence of CDI hospitalization and calculated days in hospital and costs per hospitalization. We also estimated hazard ratios (HR) for CDI hospitalization using Cox regression with age as the underlying time variable. Over a total follow-up of 1 126 708 person-years, 187 adults had an incident CDI hospitalization. The crude incidence of CDI hospitalization was 16·6/100 000 person-years, with a median hospital stay of 6 days, and a median cost of AUD 6102 per admission. Incidence increased with age and year of follow-up, with a threefold increase for 2009–2012. After adjustment, CDI hospitalization rates were significantly lower in males than females (adjusted HR 0·6, 95% confidence interval 0·4–0·7). CDI hospitalization rates increased significantly over 2009–2012. There is a need to better understand the increasing risk of CDI hospitalization in women.Y.C. received the 2014 Prime Minister’s Australia Asia Postgraduate Scholarship from the Australian Government Department of Education and Training (3929_2014).

Comparisons of management practices and farm design on Australian commercial layer and meat chicken farms: Cage, barn and free range

There are few published studies describing the unique management practices, farm design and housing characteristics of commercial meat chicken and layer farms in Australia. In particular, there has been a large expansion of free range poultry production in Australia in recent years, but limited information about this enterprise exists. This study aimed to describe features of Australian commercial chicken farms, with particular interest in free range farms, by conducting on-farm interviews of 25 free range layer farms, nine cage layer farms, nine barn layer farms, six free range meat chicken farms and 15 barn meat chicken farms in the Sydney basin bioregion and South East Queensland. Comparisons between the different enterprises (cage, barn and free range) were explored, including stocking densities, depopulation procedures, environmental control methods and sources of information for farmers. Additional information collected for free range farms include range size, range characteristics and range access. The median number of chickens per shed was greatest in free range meat chicken farms (31,058), followed by barn meat chicken (20,817), free range layer (10,713), barn layer (9,300) and cage layer farms (9,000). Sheds had cooling pads and tunnel ventilation in just over half of both barn and free range meat chicken farms (53%, n = 8) and was least common in free range layer farms (16%, n = 4). Range access in free range meat chicken farms was from sunrise to dark in the majority (93%, n = 14) of free range meat chicken farms. Over half of free range layer farms (56%, n = 14) granted range access at a set time each morning; most commonly between 9:00 to 10.00am (86%, n = 12), and chickens were placed back inside sheds when it was dusk.This study was supported by Poultry Cooperative Research Centre (CRC), http://www. poultrycrc.com.au/about-us/.
