Coastal communities, which are particularly susceptible to boil water advisories, present an understudied opportunity to understand drinking waterβ€“related behaviours and perceptions. How public health practitioners determine actions needed to prevent water-borne illness is a key factor in the public adopting messaging and/or employing behavioural change. This study involved face-to-face surveys with residents in eight coastal communities in British Columbia and Nova Scotia. All communities had recent histories of boil water advisories and/or water shortages. The findings have significant implications for public health practice seeking to reduce the incidence of water-borne diseases. For example, the respondents had a limited sense of risk of exposure to water-borne illness. This serves as a challenge for public health professionals who are tasked with educating residents about the health benefits and risks associated with drinking tap water, wherein coastal residents not concerned with water quality/availability may view this information as unnecessary. Generally, obtaining a deep understanding of place-based knowledge around health-related issues, as done here, has the potential to impact future policy and management-level decisions and lead to meaningful integration of local perspectives. Une exploration des consequences pour la sante publique des comportements et perceptions lies a l'eau potable : une enquete exploratoire realisee en face a face aupres de residents de huit communautes cotieres de la Colombie-Britannique et de la Nouvelle-Ecosse Au Canada, la qualite de l'eau potable et sa disponibilite dependent du lieu de residence. Les communautes cotieres, qui sont particulierement visees par des avis d'ebullition de l'eau, fournissent une occasion d'apporter un nouvel eclairage sur les comportements et les perceptions lies a l'eau potable. La maniere par laquelle les praticiens de la sante publique etablissent quelles actions sont requises pour prevenir les maladies hydriques est determinante tant pour l'adhesion du public aux messages que pour les changements de comportement. L'etude s'appuie sur une enquete realisee en face a face aupres de residents de huit communautes cotieres de la Colombie-Britannique et de la Nouvelle-Ecosse. L'ensemble des communautes a ete touche recemment par un avis d'ebullition de l'eau ou des penuries d'eau. Des consequences importantes pour la pratique de la sante publique visant a reduire l'incidence des maladies hydriques peuvent etre tirees des resultats de l'etude. Par exemple, les repondants sous-estimaient l'existence du risque d'etre expose aux maladies hydriques. Cela pose un defi aux professionnels de la sante publique dont le mandat consiste a sensibiliser les residants sur les bienfaits et les risques pour la sante de consommer l'eau potable du robinet, notamment quand les residents cotiers ne se preoccupent ni de la qualite ni de la disponibilite de l'eau et peuvent meme juger que ces informations sont inutiles. Posseder une solide connaissance des savoirs locaux sur les questions entourant la sante, comme on le fait ici, peut exercer une influence sur les decisions en matiere de politique et de gestion a venir et conduire a une veritable integration des perspectives locales.

Typical network models would include water demands that are allocated from billing or census data, and thus may not be appropriate for specific operational analysis, such as emergency events arising from intentional or accidental contamination. During such an event, water consumption patterns may be significantly different from those assumed when developing the hydraulic model, and may change significantly over short time periods due to the unusual circumstances of the event. To allow accurate hydraulic and water quality prediction in real-time, the water demands should be updated continuously to reflect current conditions. The development of such a real-time water demand calibration method poses many complex issues such as identifiability and uncertainty of the water demand estimates. Given the sparsity of data that are likely to be available in real time, prior statistical information about water demands must be incorporated in the calibration procedure. In this paper, a method and algorithms are proposed for a real time water demand calibration process. A predictor-corrector methodology is proposed to predict statistical hydraulic behavior based on prior estimation of water demands, and then correct this prediction using new, real-time measurements. The problem is solved using the extended Kalman filter, which is a linear algorithm that calculates the estimate of water demands and their uncertainty. As part of the Kalman filter calculation, we calculate direct sensitivities of system hydraulic responses with respect to water demands. Results of numerical experiments illustrate the impacts of statistical demand variability, hydraulic measurement accuracy and sampling design on demand estimation. This paper was presented at the 8th Annual Water Distribution Systems Analysis Symposium which was held with the generous support of Awwa Research Foundation (AwwaRF).

The ODD protocol: A review and first update	Ecological Modelling	10.1016/j.ecolmodel.2010.08.019	The β€ODDβ€™ (Overview, Design concepts, and Details) protocol was published in 2006 to standardize the published descriptions of individual-based and agent-based models (ABMs). The primary objectives of ODD are to make model descriptions more understandable and complete, thereby making ABMs less subject to criticism for being irreproducible. We have systematically evaluated existing uses of the ODD protocol and identified, as expected, parts of ODD needing improvement and clarification. Accordingly, we revise the definition of ODD to clarify aspects of the original version and thereby facilitate future standardization of ABM descriptions. We discuss frequently raised critiques in ODD but also two emerging, and unanticipated, benefits: ODD improves the rigorous formulation of models and helps make the theoretical foundations of large models more visible. Although the protocol was designed for ABMs, it can help with documenting any large, complex model, alleviating some general objections against such models.

Virtualisation of floricultural supply chains	Computers and Electronics in Agriculture	10.1016/j.compag.2013.09.006	We assess how the Internet of Things can enhance virtualisation in floriculture.We define the concept of virtualisation and different perspectives in literature.A conceptual framework for analysis of virtual supply chains is developed.We analyse the existing situation and future challenges in Dutch floriculture. Supply chains are increasingly virtualised in response to market challenges and to opportunities offered by nowadays affordable new technologies. Virtual supply chain management does no longer require physical proximity, which implies that control and coordination can take place in other locations and by other partners. This paper assesses how the Internet of Things concept can be used to enhance virtualisation of supply chains in the floricultural sector. Virtualisation is expected to have a big impact in this sector where currently still most products physically pass through auction houses on their fixed routes from (inter)national growers to (inter)national customers. The paper defines the concept of virtualisation and describes different perspectives on virtualisation in literature, i.e. the organisational, team, information technology, virtual reality and virtual things perspectives. Subsequently it develops a conceptual framework for analysis of virtualisation in supply chains. This framework is applied in the Dutch floriculture to investigate the existing situation and to define future challenges for virtualisation in this sector.

The technology can provide near real-time monitoring of where water is used in the home, disaggregated by end-use (shower, toilet, clothes washing, garden irrigation, etc.). This paper explores questions regarding the degree of information detail required to assist utilities in targeting demand management programs and informing customers of their usage patterns, whilst ensuring privacy concerns of residents are upheld.

Stay-at-Home Orders during the COVID-19 Pandemic Reduced Urban Water Use	Environmental Science and Technology Letters	10.1021/acs.estlett.0c00979	In response to the outbreak of the COVID-19 pandemic, many governments instituted β€_x009c_stay-at-homeβ€_x009d_ orders to prevent the spread of the coronavirus. The resulting changes in work and life routines had the potential to substantially perturb typical patterns of urban water use. We present here an analysis of how these pandemic responses affected Californiaβ€™s urban water consumption. Using water demand modeling that fuses an integrated water use database, we first simulated the water use in a business-as-usual (non-pandemic) scenario for essentially all urban areas in California. We then subtracted the business-as-usual water use from the actual use to isolate the changes caused solely by the pandemic response. We found that the pandemic response decreased Californiaβ€™s urban water use by 7.9\%, which can be largely attributed to an 11.2\% decrease in the commercial, industrial, and institutional sector that more than offset a 1.4\% increase in the residential sector. The influence of the stay-at-home practices on urban water use is slightly stronger than the combined influences of all non-pandemic factors. This study covers both metropolitans and suburbs; therefore, the results could also be useful for analysis of the impacts of COVID-19 on water use in other urban areas.

Diffusion of Emergency Warning: Comparing Empirical and Simulation Results		10.1007/978-1-4899-0730-1_14	As officials consider emergency warning systems to alert the public to potential danger in areas surrounding hazardous facilities, the issue of warning system effectiveness is of critical importance. The purpose of this paper is to present the results of an analysis on the timing of warning system information dissemination including the alert of the public and delivery of a warning message. A general model of the diffusion of emergency warning is specified as a logistic function. Alternative warning systems are characterized in terms of the parameters of the model, which generally constrain the diffusion process to account for judged maximum penetration of each system for various locations and likelihood of the publicβ€™s being in those places by time of day. The results indicate that either telephone ring-down warning systems or tone-alert radio systems combined with sirens provide the most effective warning system under conditions of either very rapid onset, close proximity or both. These results indicate that single technology system provide adequate warning effectiveness when available warning time (after detection and the decision to warn) extends to as much as an hour. Moreover, telephone ring-down systems provide similar coverage at approximately 30 minutes of available public warning time.

A Hybrid Agent-Based Model for Estimating Residential Water Demand	Simulation	10.1177/0037549705053172	The global effort toward sustainable development has initiated a transition in water management. Water utility companies use water-pricing policies as an instrument for controlling residential water demand. To support policy makers in their decisions, the authors have developed DAWN, a hybrid model for evaluating water-pricing policies. DAWN integrates an agent-based social model for the consumer with conventional econometric models and simulates the residential water demand-supply chain, enabling the evaluation of different scenarios for policy making. An agent community is assigned to behave as water consumers, while econometric and social models are incorporated into them for estimating water consumption. DAWN's main advantage is that it supports social interaction between consumers, through an influence diffusion mechanism, implemented via inter-agent communication. Parameters affecting water consumption and associated with consumers' social behavior can be simulated with DAWN. Real-world results of DAWN's application for the evaluation of five water-pricing policies in Thessaloniki, Greece, are presented.
