Feasibility Assessment of Using Geoinformatics Technology in Disaster Disease Surveillance in a Developing Country, Iran
April 14, 2015 • Research article
Background and purpose: Geoinformatics technology retains an unprecedented trait of performing with a supersonic speed and precision in public health management whereas the existing disease surveillance systems in developing countries lack using this technology. This article aims to assess the feasibility of using geoinformatics technology in disaster disease surveillance in a developing country, Iran.
Methods: A self-administered questionnaire was developed based on technology acceptance model (TAM), and a semi-quantitative survey was conducted in order to collect data. Fifty TUMS & HS personnel, currently involve in disease surveillance and information technology, were included. Initially, a pilot study was conducted to test the validity and reliability of the questionnaire. Cronbach alpha, confirmatory factor analysis (CFA), and standard error of measurement (SEM) were calculated to validate the causal model.
Results: The results from structural equation analysis suggested that TAM provided a constructive picture of using geoinformatics technology in disaster disease surveillance at TUMS &HS. The study found attitude (ATT) had a significant influence on participants intention to use (ITU) a new technology, and perceived ease of use (PEOU) was a strong determinant of perceived of usefulness (PU). Subsequently, PU and PEOU explained ATT substantially; even though the analysis showed insignificant statistical association among these constructs. The high R2 (Coefficient of determination) of the constructs described respondents positive instinct towards accepting a new technology.
Conclusion: The study reveals that personnel intent to adopt geoinformatics technology in disaster disease surveillance; and at the same time, they possess a positive attitude towards the technology. This study also found PEOU has a strong influence on PU, so information sessions and training on geoinformatics technology need to focus primarily on the applications and impacts of technology on disaster disease surveillance.

The Potential Impact of Directionality, Colour Perceptions and Cultural Associations on Disaster Messages During Heatwaves in the UK
April 14, 2015 • Research article
The health risks posed by heatwaves have been well documented. In the UK, before and during a heatwave, alerts are issued to the general public based on a tiered warning system integrating the use of colour and number sequences. There has of yet been no formal assessment of the public response to these messages. Cultural and language barriers make some members of ethnic minority communities particularly hard to reach. These may be less challenging amongst younger community members, who may be well placed to instigate the circulation of warning information to those less able or willing to use conventional channels.
This qualitative study assesses the role of age and ethnic and cultural background in the conceptualisation of the number and colour systems used as part of the Heat-Health Watch System (HHWS) and the National Severe Weather Warning Service (NSWWS). Young and older participants were recruited from the Bangladeshi and white British populations of Tower Hamlets. All participants were given a cognitive task that required them to identify and draw associations between 12 cards depicting the four colours and numbers used in the warning system and four pictures providing contextualisation in terms of heatwave risk. A qualitative analysis of the heuristics used in the group discussions provided insights into the conceptualisations basic to interpreting colour and number sequences as representations of risk graduations, and how interpretation might be influenced by age and ethnic and cultural background.
There were considerable differences in the interpretation of young Bangladeshi and older white British participants, on the one hand, and older Bangladeshi participants, on the other. Young Bangladeshis and older white British participants conceptualised the colours and numbers as a vertical scale, with the numbers/colours at “the top” corresponding to representations of higher temperature. This conceptualisation was mainly based on strong associations between colour and temperature, with risk only associated with the upper limit of the scale. Older Bangladeshi participants, on the other hand, conceptualised the numbers and pictures as a narrative sequence and disassociated the colours from the other cards. The differences between groups suggest potential cultural barriers to the “intended” interpretation of the colour and number sequences for older Bangladeshis but not for young Bangladeshis. The fact that the predominant association for the colour sequence for both young Bangladeshis and older white British participants was with graduations of temperature rather than risk raises questions about the applicability of using colours in a tiered warning system.

Managing the Earth’s Biggest Mass Gathering Event and WASH Conditions: Maha Kumbh Mela (India)
April 13, 2015 • Research article
Background: Mass gatherings including a large number of people makes the planning and management of the event a difficult task. Kumbh Mela is one such, internationally famous religious mass gathering. It creates the substantial challenge of creating a temporary city in which millions of people can stay for a defined period of time. The arrangements need to allow this very large number of people to reside with proper human waste disposal, medical services, adequate supplies of food and clean water, transportation etc.
Methods: We report a case study of Maha Kumbh, 2013 which focuses on the management and planning that went into the preparation of Kumbh Mela and understanding its water, sanitation and hygiene conditions. It was an observational cross-sectional study, the field work was done for 13 days, from 21 January to 2 February 2013.
Results: Our findings suggest that the Mela committee and all other agencies involved in Mela management proved to be successful in supervising the event and making it convenient, efficient and safe. Health care services and water sanitation and hygiene conditions were found to be satisfactory. BhuleBhatke Kendra (Center for helping people who got separated from their families) had the major task of finding missing people and helping them to meet their families. Some of the shortfalls identified were that drainage was a major problem and some fire incidents were reported. Therefore, improvement in drainage facilities and reduction in fire incidents are essential to making Mela cleaner and safer. The number of persons per toilet was high and there were no separate toilets for males and females. Special facilities and separate toilets for men and women will improve their stay in Mela.
Conclusion: Inculcation of modern methods and technologies are likely to help in supporting crowd management and improving water, sanitation and hygiene conditions in the continuously expanding KumbhMela, in the coming years.
