The influence of oversizing on maintenance cost in wastewater treatment plants
2021
Abstract Management of Wastewater Treatment Plants (WWTPs) is a complex process, not only from a technical point of view but also from an economic point of view. There are several factors that influence the wastewater treatment process and can cause an increase in management costs. One of these factors is the treatment capacity, in particular the WWTPs’ oversizing problem. The difference between the design population equivalent (p.e.) and the actual p.e. treated generates imbalances in the wastewater treatment process costs. This paper analyses the influence that oversizing has on the maintenance costs for WWTPs in the Valencia region (Spain). Through an econometric approach, the behaviour …
Building Resilience Through Effective Disaster Management
2017
Existing literature argues that taking a holistic approach to disaster management is important for organizations in building resilience. Theoretical underpinnings to achieve a holistic understanding, however, is lacking. This article applies the notion of an ecosystem as a holistic lens to understand complex disaster management. The paper reports two case studies from Japan and Nepal to illustrate how an ecosystem works during a disaster. The theoretical framework of information ecology is used in analyzing the cases. Based on the findings, the study shows three interconnected mechanisms that can build resilience of an ecosystem in a disaster management context, namely (1) coevolution, (2) …
Event Management and Terrorism in a Global Order
2020
Over the recent years, the public spectacle and media events have become fertile grounds for terrorist attacks. Particularly, media events play a leading role enhancing the social cohesion as well as revitalizing the psychological frustrations that happened during the working days. Paradoxically, terrorism needs to maximize its gains while the costs are minimized. The spectacularisation tourism and events offer a double-edge sword. The same attractiveness that makes global cities a safer place to live are employed by the terrorist cells to cause chaos and uncertainty. The chapter theoretically explores the difficult interrelation between terrorism and event management as well as the concept…
Sustainable growth and environmental catastrophes
2017
Abstract In the standard AK growth model we introduce the threat of an ecological catastrophe and study the consequences for the economic variables in the long-run. We extend the basic framework by considering two environmental externalities: the first one is local and gives account of the marginal damage from emissions flow; the second one is aggregate, or global, and relates to the extreme damage which may happen if the accumulated stock of pollutants is on the threshold of a worldwide catastrophe. In this context dominated by market failures, we focus on the socially optimal solution and the search of conditions for sustainability. We identify the efficient balanced growth path, which ma…
The Camorra and protection rackets: the cost to business
2016
Based on the observations from the judicial and investigative evidence provided by prosecutors in Camorra areas in Italy, this investigation provides an estimate of the economic impact of extortion racket to businesses. In particular, the estimates refer to the total and average withdrawal of monetary amounts from the businesses victimised by Camorra clans. Further insights are provided in terms of economic activities mostly victimised, and specifically the construction sector, which is subject to a different type of extortion racket.
BDI Modelling and Simulation of Human Behaviours in Bushfires
2016
Each summer in Australia, bushfires burn many hectares of forest, causing deaths, injuries, and destruction of property. Emergency management strategies rely on expected citizens’ behaviour which differs from reality. In order to raise their awareness about the real population behaviour, we want to provide them with a realistic agent-based simulation. The philosophically-grounded BDI architecture provides a very suitable approach but is little used due to the lack of adapted tools. This paper uses this case study to illustrate two new tools to fill this gap: the Tactics Development Framework (TDF) and GAMA BDI architecture.

Geschlecht als Differenzierungskategorie (in Führungspositionen) des Sports
2017
Am 26. Februar 2016 verabschiedeten die 207 stimmberechtigten Delegierten des auserordentlichen FIFA1-Kongress ihr neues Reformpaket. Neben einer Vielzahl von Veranderungen wurde hierbei auch erstmals die Einfuhrung einer Frauenquote beschlossen. Danach soll zukunftig „jede der sechs Konfoderationen (…) mindestens eine Frau in den FIFA-Rat entsenden. Als Ziel wird eine Frauenquote von 30 Prozent genannt.“ (zdfsport.de: 2016).
Covid-19 in Deutschland – Erklärung, Prognose und Einfluss gesundheitspolitischer Maßnahmen
2020
Zusammenfassung Die Autoren erklären den bisherigen Verlauf von Covid-19 in Deutschland durch Regressionsanalysen und epidemiologische Modelle. Sie beschreiben und quantifizieren den Effekt der gesundheitspolitischen Maßnahmen (GPM), die bis zum 19. April in Kraft waren. Sie berechnen den erwarteten Verlauf der Covid-19-Epidemie in Deutschland, wenn es diese Maßnahmen nicht gegeben hätte, und zeigen, dass die GPM einen erheblichen Beitrag zur Reduktion der Infektionszahlen geleistet haben. Die seit 20. April gelockerten GPM sind zwischen den Bundesländern relativ heterogen, was ein Glücksfall für die Wissenschaft ist. Mittels einer Analyse dieser Heterogenität kann aufgedeckt werden, welche…
La performance hospitalière : à la recherche d'un modèle multidimensionnel cohérent
2009
Cet article a pour ambition de proposer un modele multidimensionnel coherent de la performance hospitaliere. En effet, le secteur hospitalier doit repondre a une performance globale et multidimensionnelle (qualite et securite des soins, utilisation optimale des ressources, productivite, satisfaction du patient, etc.). En France, aucun modele integrant les differentes dimensions de la performance hospitaliere n’a pour l’instant ete instaure alors que l’hopital public est au centre d’enjeux essentiels pour son avenir. Pour construire ce modele, nous nous appuierons d’une part sur une comparaison des systemes hospitaliers de trois pays anglo-saxons et d’autre part, sur une revue des cadres con…
