The Way

The unsustainable development of countries has created a problem due to the unstoppable waste generation. Moreover, waste collection is carried out following a pre-defined route that does not take into account the actual level of the containers collected. Therefore, optimizing the way the waste is collected presents an interesting opportunity. In this study, we tackle the problem of predicting the waste generation ratio in real-world conditions, i.e., under uncertainty. Particularly, we use a deep neuroevolutionary technique to automatically design a recurrent network that captures the filling level of all waste containers in a city at once, and we study the suitability of our proposal when faced to noisy and faulty data. We validate our proposal using a real-world case study, consisting of more than two hundred waste containers located in a city in Spain, and we compare our results to the state-of-the-art. The results show that our approach exceeds all its competitors and that its accuracy in a real-world scenario, i.e., under uncertain data, is good enough for optimizing the waste collection planning.

The Subject

The lack of examples of smart-city initiatives and the sharing of best practices in Portugal confirm the gap in the transference of empirical knowledge to the scientific literature in this area. The smart-city concept has passed through three stages. However, its evolution has not been noted equally throughout countries and their territories. The literature only provides information about specific projects implemented in a few cities. Therefore, the aim of this paper was to study the state-of-the-art of smart cities in Portugal by analyzing 25 editions of the most relevant national-wide smart-cities magazine. First, the objective of analyzing the magazine was to study each Portuguese city in terms of the subject areas and types of existing initiatives in order, ultimately, to frame cities within their respective smart-city phases, as per the literature. Second, the aim of the paper was also to provide information about the evolution of the concept through analyses of embedded experts’ quotes. The results of the first are complemented with the analysis of interviews with policymakers to provide information about the existing challenges to implementing a smart city and to understand the role of government therein. Qualitative and quantitative analyses were performed on the case study. The findings suggest that the three smart-city phases are perceived in slightly different ways in Portugal and heterogeneity within the country can be noted from the lack of strategies and a standard framework.

This chapter provides an overview of the state of the art concerning the application of ICTs in parliaments and of the main problems identified when considering engaging the public through ICTs. Using the Portuguese Parliament as a case study, the chapter analyzes some effective approaches using ICTs to involve citizens and to support the dialogue regarding the legislative process. The conclusion emerging from the chapter is that the use of ICTs is not enough to get citizens to trust the parliament and to maintain their involvement. Parliaments need to follow a strategic and coherent plan that considers other questions apart from technology and goes beyond making documents available to the public. Parliaments need to ensure that their information systems provide both information and communication and meet the criteria of clarity, accuracy, timeliness, completeness, and the provision of feedback.

The State

This introduction reviews the state of the art in the study of women's monasticism between 800 and 1050, draws attention to the inconsistencies in traditional accounts, and develops a new way of looking at the primary evidence to reconstruct a more accurate narrative. Besides presenting the case study of forty communities in Lotharingia, it also outlines the triple hypothesis of the book.
