The recycling of anthropogenic nutrients derived from the wastewater management systems is often characterized by a complex and uncertain scenario, due not only to the nature of the process but also to the involvement of different stakeholder groups. Over the past 10 years in Switzerland, policies regarding the use of sewage sludge as fertilizer have gradually shifted to a ban on use in agriculture. As a result, alternative methods for the recycling of anthropogenic nutrients may play a relevant role in the near future. This paper uses the analytic hierarchy process (AHP) to examine more closely the nutrient-recycling dilemma by analysing the preferences of a group of German-speaking residents in the city of Zurich for various management scenarios. Nutrient recycling by the use of urine separation toilets and the BioCon treatment process are presented as possible management alternatives in addition to current practice. The study shows that AHP can incorporate the respondents' preferences and multiple objectives when evaluating alternatives with different attributes.

The rainwater system is an important part of the urban infrastructure as well as a key hub for maintaining the dynamic operation of the city and a clear indicator of the level of urban development. With the rapid development of urbanization, the hardened area of roads and residential areas has increased, and the construction of rainwater systems is so far insufficient, causing the urban waterlogging and water pollution problems to become increasingly serious. Accordingly, combined with the “sponge city” construction concept of the six-character policy of “seepage, retention, storage, use, purification, and drainage,” we propose to adopt measures for the local conditions and to reasonably select sponge city engineering measures to increase rainwater utilization, effectively reduce rainwater runoff, and alleviate the city waterlogging and water pollution problems. We used the analytic hierarchy process (AHP) to evaluate the effect of a sponge city “pocket park” rainwater system in Chaohu City before and after the transformation. The results showed that the pocket park after the renovation was well controlled, the waterlogging was basically eliminated, the water quality pollution was clearly improved, and the ecological environment was significantly improved.

<p>Professor Enrique Mu, Editor-in-Chief of the International Journal of the AHP (on the right), honored by Mayor Luke Ravenstahl for helping the City of Pittsburgh select the best technology to move its Information Technology functions to the Cloud, a tough decision that had to be made by city officials. Professor Mu used AHP (the Analytic Hierarchy Process for decision-making) to guide the process, facilitating it over a period of months.</p><p>http://dx.doi.org/10.13033/ijahp.v3i1.92</p>

Objectives: To identify early suicide risk signs on depressive subjects, so that specialized care can be provided. Various studies have focused on studying expressions on social networks, where users pour their emotions, to determine if they show signs of depression or not. However, they have neglected the quantification of the risk of committing suicide. Therefore, this article proposes a new index for identifying suicide risk in Mexico. Methodology: The proposal index is constructed through opinion mining using Twitter and the Analytic Hierarchy Process. Contribution: Using R statistical package, a study is presented considering real data, making a classification of people according to the obtained index and using information from psychologists. The proposed methodology represents an innovative prevention alternative for suicide.
