Technological innovations have revolutionized the lifestyle of the society and led to the development of advanced and intelligent cities. Smart city has recently become synonymous of a city characterized by an intelligent and extensive use of Information and Communications Technologies (ICTs) in order to allow efficient use of information. In this context, this paper proposes a new approach to optimize the planning of itineraries for one-day tourist. More in detail, an optimization approach based on Graph theory and multi-algorithms is provided to determine the optimal tourist itinerary. The aim is to minimize the travel times taking into account the tourist preferences. An Integer Linear Programming (ILP) problem is introduced to find the optimal outward and return paths of the touristic itinerary and a multi-algorithms strategy is used to maximize the number of attractions (PoIs) to be visited in the paths. Finally, a case study focusing on cruise tourist in the city of Bari, demonstrates the efficiency of the approach and the user interaction in the determination of the itinerary.

Roll Out

Information and communications technologies (ICTs) promise development gains, yet the complexity and opacity of the relationships between ICT initiative and development effect makes it difficult to identify these development gains or to theorize connections. This case study does both. First, it identifies the connections between the roll-out of free public Wi-Fi by the City of Johannesburg and changes that have resulted in city residents' lives. Second, it uses the choice framework to explain how these changes come about. This qualitative case study conducted interviews with users of the city's free public Wi-Fi service to understand how the service has changed the choices they have, leading to development in the sense of increased capabilities. Benefits identified included easier communications, savings in time and money, social and psychological benefits, as well as increased knowledge, business ideas, access to markets, access to job opportunities, and increased income. This study demonstrates how the linkages can be understood, albeit not in a linear fashion.

Abstract Today, Algeria is one of the developing countries that are engaging seriously into a new approach consisting of all kinds of combined risk assessments for better prevention them. Note that, this is a fairly important parameter, that is, the safety of people and property. However, the magnitude of the risk, of whatever nature, affects a variety of diversified aspects (Human, economic, technical and environmental). This study presented a case study, which is sometimes paradoxical, seeing that it is the result of the combination of all risk factors and specific factors related to them connected to a fragile urban environment: Hassi-Messaoud. It is well known that Hassi-Messaoud is one of the most important city for Algeria's economy; in which the demographic development is mainly known by incessant flows of immigrants, motivated essentially by job search. This arbitrary of population distribution exposes this city to a certain danger; especially as Hassi-Messaoud is in a zone subject to a probable risk expressed here by being characteristic of an oil zone. Thus, this article aimed to provide elements of risk assessment related to oil activity. This approach could conclude that, through a schematic scale, the different types and levels of exposure and vulnerability could be identified, that is, characteristics of the urban space in question.

Today's complex, unstable and competitive society raises several difficulties to organisations. In this context, Information and Communications Technologies (ICT) and information itself have become resources of vital importance. The pressing need for Information Systems (IS) to meet several business requirements, in addition to the complexity involved in technology and business management, turns the IS Function one of the main areas of influence for success of modern organisations. Through its capacity of representing activities, management objects and corresponding relations, the Information Architecture of the Information Systems Function (IAISF), a technique derived from the well-known Information Architecture but exclusively focused on the Information Systems Function (ISF), allows not only the conceptualization and understanding of the ISF itself, but also of its interactions with other areas within organizations. This paper presents the main results of a case study related to the application of the IAISF technique in a computer service centre of a University.

One of the cornerstones of Democracy is the participation of citizens in decisions that affect their lives. This participation, traditionally, is exercised: a) through national elections and the body of representatives, and b) through binding procedures such as referendums. However, there are decisions that affect citizens’ everyday lives that require more frequent, day to day participation. Information and Communications Technologies (ICT) can create fast and secure communication channels, enabling politicians and citizens to engage in a mutually rewarding interaction leading to the development eDemocracy. However, lack of trust either between politicians and citizens or lack of trust of citizens towards ICT can raise barriers to this opportunity. In this chapter we discuss the issue of trust among government, citizens, and ICT. Our view is that it is nowadays possible to, at least, handle effectively the citizen-ICT facet of trust and provide the drivers for the convergence of eGoverment and eDemocracy realizing the concept of eGovernance. As a case study we present our experiences from the design and implementation of an eVoting system, which has the same strong relationship with eGovernance as traditional elections have with Governance.

This article examines some of the challenges faced by local government during the development and implementation of a relatively new area of e-democratic innovation in Australia: e-consultation. E-consultation is seen as a valuable way through which a two-way relationship can be developed and enhanced between citizens and elected representatives. It involves the use of information and communications technologies (ICTs), such as the Internet, to extend and/or enhance political democracy through access to information, and to facilitate participation in democratic communities, processes, and institutions. Drawing on a case study of the Darebin eForum in Victoria, Australia, this article focuses on the role of public servants as moderators of this local form of e-consultation. The discussion has three parts: online policy consultation is defined within the context of e-democracy; some of the ways that e-consultation challenges the roles of the public service, elected representatives, and citizens are outlined; and the author then argues for an e-consultation strategy that is situated within a continuum of citizen engagement that is ongoing, deliberative, educative, and inclusive.

Regional bioeconomy development is directly linked to the availability and access to bioresources. Therefore, it is necessary to trigger opportunities for information and communications technologies (ICTs), the Internet of things (IoT) and Industry 4.0 solutions to increase the efficiency of high potential value biomass supply chains, improving this way the accessibility of bioresources. This study aims to present the results achieved through the development of Digital Innovation Hubs (DIHs) as a tool able to boost biomass valorisation, reshaping regional bioeconomy. The objective was to shape these DIHs and assess how stakeholders could be engaged and benefit from such initiatives. This has been attained through the design and implementation of DIHs in two case-study regions, Andalusia (Spain) and south-east Ireland (Ireland). The approaches and results for stakeholders’ engagement, barrier mitigation, DIH structure and activities are presented. So far, more than 100 stakeholders have been engaged, more than 50 business opportunities have been promoted and a set of support services and events have been carried out. Main lessons learned are (1) about the relevance of understanding the needs of stakeholders, (2) impact is bigger when relevant regional industries (rather than academia/technology providers) discuss the technologies they have integrated and how these have improved efficiency or added value to their processes, and (3) about the importance of the communication plan and a well-formed DIH service definition.

This article proposes a methodology to address the urban evolutionary process, demonstrating how it is reflected in literature. It focuses on “literary space,” presented as a territory defined by the period setting or as evoked by the characters, which can be georeferenced and drawn on a map. It identifies the different locations of literary space in relation to urban development and the economic, political, and social context of the city. We suggest a new approach for mapping a relatively comprehensive body of literature by combining literary criticism, urban history, and geographic information systems (GIS). The home-range concept, used in animal ecology, has been adapted to reveal the size and location of literary space. This interdisciplinary methodology is applied in a case study to nineteenth- and twentieth-century novels involving the city of Lisbon. The developing concepts of cumulative literary space and common literary space introduce size calculations in addition to location and structure, previously developed by other researchers. Sequential and overlapping analyses of literary space throughout time have the advantage of presenting comparable and repeatable results for other researchers using a different body of literary works or studying another city. Results show how city changes shaped perceptions of the urban space as it was lived and experienced. A small core area, correspondent to a part of the city center, persists as literary space in all the novels analyzed. Furthermore, the literary space does not match the urban evolution. There is a time lag for embedding new urbanized areas in the imagined literary scenario.

Situational Awareness (SAW) refers to the level of consciousness that an individual or team holds over a situation. In the area of ​​risk management and criminal data analysis, SAW failures can induce human operators to make mistakes in decision making and pose risks to life or property. In this context, risk assessment processes, which commonly involves data mining, fusion and other methods, present opportunities to generate better information and contribute to the improvement of the SAW of crime and risk analysts. However, the characterization of complex scenarios is subject to problems of representation and expressiveness of the information, which may influence its interpretation due to their quality and significance, generating uncertainties. The state-of-the-art in representation of information on risk situations and related areas presents approaches with limited use of information quality. In addition, the solutions are restricted to syntactic mechanisms for the determination of relations between information, negatively restricting the assertiveness of the results. Thus, this paper aims to develop a new approach to semantic representation of information of risk situations, more specifically creating domain ontologies, instantiated with crime data and information quality. In a case study, real information on crimes, represented by the new semantic model and consumed by computational inference processes, was be processed, aiming to characterize robbery and theft situations.

Educational leadership is essential to implement information and communications technologies in schools but the leadership practice of information and communications technologies coordinators, a position role that supports teachers to implement information and communications technologies, appears limited. The present study applies a distributed perspective to leadership and investigates aspects of information and communications technologies coordinator context that would facilitate leadership. Twenty-seven information and communications technologies coordinators were surveyed on their schools’ structures and mechanisms that mediate their leadership practice. Descriptive statistics show that a wide range of structures and mechanisms in different quantities and with different qualities can be available to coordinators. The majority of coordinators have neither additional position roles nor a teaching load, but the coordinators have organizational unit assignments and attend daily, routine interactions. A case study illustrates how specific structures and mechanisms would facilitate leadership for information and communications technologies implementation. It is recommended to design an information and communications technologies coordinator role as a formal position role, for a school to employ more than one information and communications technologies coordinator, and to develop an information and communications technologies coordinator’s teaching load, organizational unit assignments and routine interactions according to school needs. Several possible populations of information and communications technologies coordinators are identified for further research.

As the integration of information and communications technologies (ICT) in Singapore schools reaches a considerable level of maturity and stability, a pertinent question is: how has ICT integration impacted on pedagogy in Singapore schools? The present study attempts to address this question through interpretive, case-study research in two Singaporean secondary schools. The study found the use of ICT was limited in its perceived pedagogical value by teachers. A lack of appreciation and/or understanding of the complexity of the process or culture shift required for ICT to be implemented and integrated effectively into the Malay Language Curriculum along with conformity to policy directions resulted in underutilisation and uncritical use of ICT tools, and an adherence to the traditional method of assigning tasks and the maintenance of existing practices.
