1 Developing an integrated risk management framework for agricultural water conveyance and distribution systems within fuzzy decision making approaches
ایجاد یک چارچوب مدیریت ریسک یکپارچه برای سیستم های انتقال و توزیع آب کشاورزی در رویکرد تصمیم گیری فازی-2018
Irrigation canal networks, as the primary agricultural water conveyance and delivery systems, are exposed to a variety of hazards affecting the water distribution processes. This study, for the first time, develops a comprehen sive risk management framework for the canal network through a Fuzzy Hierarchical method. In this regard, the risk is analyzed by a combination of probability, consequence, and vulnerability against identified hazards based on the hierarchical framework. The developed model is based on fuzzy numbers to consider the uncertainties arise from experts opinion. To aggregate the calculated risk in the hierarchical framework, the Fuzzy Simple Ad ditive Weighting (FSAW) approach was employed. To enhance the reliability of the water distribution system and decrease the risk of failure, six risk management alternatives are proposed based on the risk assessment re sults and the most significant hazards. To prioritize managerial scenarios, two sets of criteria were selected in cluding quantitative criteria (consisting of cost of operation and risk reduction) and a qualitative set (compromising social and operational criteria). The risk management scenarios were prioritized based on two rational multi-criteria decision-making (MCDM) methods of a Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Simple Additive Weighting (SAW). Regarding different degrees of importance of the criteria, a pair-wise comparison was conducted by a group of experts to determine the relative weight of the criteria. According to the risk assessment results, the riskiest hazards are poor maintenance, seepage, unex pected event, drought, and vandalism of the structure. Moreover, employing the MCDM model in risk-based

2 Vandalism and tourism settings: An integrative review
تنظیمات واندیالیسم و گردشگری: یک مرور جامع-2016
Although wide agreement exists in the literature concerning the presence of vandalism in tourism, very little attention has been given to studying the phenomenon. This paper reviews published literature that addresses vandalism, its manifestation in tourism and its prevention. The review provides a compre hensive analysis of empirical research on the motivations for vandalism, deviant visitor behaviour and intervention strategies to manage such behaviours in tourism settings. The paper reviews the micro-level and macro level forces influencing vandalism and provides a definition, thematic analysis of current literature on motivation of vandalism and common themes in vandalism prevention. The analysis demonstrates a range of intervention strategies to curb vandalism. An evolution towards the use of more refined proactive techniques is apparent in recent work. The review provides a foundation for further work by theorists and practitioners.
