    Flooding is a major global hazard whose management relies on an accurate understanding of its risks. Crowdsourcing represents a major opportunity for supporting flood risk management as members of the public are highly capable of producing useful flood information. This thesis explores a wide range of issues related to flood crowdsourcing using an interdisciplinary approach. Through an examination of 31 different projects a flood crowdsourcing typology was developed. This identified five key types of flood crowdsourcing: i) Incident Reporting, ii) Media Engagement, iii) Collaborative Mapping, iv) Online Volunteering and v) Passive VGI. These represent a wide range of initiatives with radically different aims, objectives, datasets and relationships with volunteers. Online Volunteering was explored in greater detail using Tomnod as a case study. This is a micro-tasking platform in which volunteers analyse satellite imagery to support disaster response. Volunteer motivations for participating on Tomnod were found to be largely altruistic. Demographics of participants were significant, with retirement, disability or long-term health problems identified as major drivers for participation. Many participants emphasised that effective communication between volunteers and the site owner is strongly linked to their appreciation of the platform. In addition, the feedback on the quality and impact of their contributions was found to be crucial in maintaining interest. Through an examination of their contributions, volunteers were found to be able to ascertain with a higher degree of accuracy, many features in satellite imagery which supervised image classification struggled to identify. This was more pronounced in poorer quality imagery where image classification had a very low accuracy. However, supervised classification was found to be far more systematic and succeeded in identifying impacts in many regions which were missed by volunteers. The efficacy of using crowdsourcing for flood risk management was explored further through the iterative development of a Collaborative Mapping web-platform called Floodcrowd. Through interviews and focus groups, stakeholders from the public and private sector expressed an interest in crowdsourcing as a tool for supporting flood risk management. Types of data which stakeholders are particularly interested in with regards to crowdsourcing differ between organisations. Yet, they typically include flood depths, photos, timeframes of events and historical background information. Through engagement activities, many citizens were found to be able and motivated to share such observations. Yet, motivations were strongly affected by the level of attention their contributions receive from authorities. This presents many opportunities as well as challenges for ensuring that the future of flood crowdsourcing improves flood risk management and does not damage stakeholder relationships with participants

    Plan on the move : mobile participation in urban planning state-of-the-art and future potential

    Citizen participation in urban planning has been a topic of academic and practical interest since the 1960s. The adoption of information and communication technologies for civic participation, electronic participation, impacts how citizens and urban planners interact. Within the field of electronic participation, mobile participation is a rather recent chapter. The proliferation of mobile technologies enables both novel forms of participation and the embeddedness of these technologies into existing practices of participation. This dissertation contains five studies exploring how emerging practices of mobile participation are changing citizen participation in urban planning. Each of the five studies describes a facet of mobile participation, beginning with an overview of participatory planning apps in use; exploring next how citizens develop apps themselves; turning then to the theoretical basis of mobile participation grounded in previous theories of participation and the digital divide; covering further the actual usage of the Täsä urban planning app; and finally, discussing self-organized community planning using mobile technologies. The results provide an overview of the specific features enhancing democratic urban planning, asses who develops mobile apps and with what intentions, and contrasts the circumstances conducive to inclusiveness in mobile participation. Mobile phones are ubiquitous and possess a combination of unique affordances such as situated engagement and participatory sensing, enabling rich, real-time data collection and experimentation. These features resonate with early adopters who, in order to affect change, need to be embedded in the institutional civic participation setting. For citizens, mobile technologies have diversified the roles of participation, so that citizens can choose between being informed, contributing ideas, or developing applications. Finally, the apps developed with open data are the result of negotiations between developers’ agency and open data availability. Overall, this dissertation suggests that mobile participation is socially constructed in as far as the features and practices implemented are subject to a host of stakeholder interests. To this end, mobile participation is conceptualized as maximum allowed deviation: it affords new practices that reshape citizen participation while being part of established forms of civic participation.Kansalaisten osallistuminen kaupunkisuunnitteluun on kiinnostanut sekä tiedeyhteisöä että suunnittelijoita jo 1960-luvulta lähtien. Informaatio- ja kommunikaatioteknologian omaksuminen sekä sähköinen osallistuminen ovat vaikuttaneet siihen, miten kaupunkilaiset ja suunnittelijat ovat vuorovaikutuksessa toisiinsa. Mobiiliosallistuminen on uusi sähköisen osallistumisen ilmiö. Mobiililaitteiden nopea leviäminen sekä mahdollistaa uusia osallistumismuotoja että sulautuu jo olemassa oleviin käytäntöihin niitä muuntaen. Tämä väitöskirja koostuu viidestä artikkelista, joissa tutkitaan miten mobiiliosallistuminen muuttaa kansalaisten osallistumista kaupunkisuunniteluun. Osatutkimukset tarkastelevat mobiiliosallistumista eri näkökulmista. Ensimmäiseksi on kartoitettu millaisia kaupunkisuunnitteluun ja kaupunkien hallintaan osallistavia sovelluksia maailmassa oli käytössä vuoteen 2015 mennessä. Toiseksi on tutkittu, miten kansalaiset osallistuvat itse sovelluksien kehittämiseen avoimen datan kilpailuissa. Kolmanneksi on tutkittu edellytyksiä mobiiliosallistumiselle, perustaen tarkastelu sosiaalisiin ja poliittisiin osallistumisteorioihin sekä digitaalisen kuilun ylittämistä koskeviin tutkimuksiin. Neljännessä osatutkimuksessa esitellään Turussa 2015 toteutetun mobiiliosallistumisen kokeilun (Täsä) tuloksia ja viidennessä käsitellään mobiiliteknologian käyttöä kaupunkilaisten itse-organisoituvassa osallistumisessa. Tulokset kertovat miten teknologiset ominaisuudet muuttavat osallistuvaa kaupunkisuunnittelua, mikä ja mitkä tahot vaikuttavat sovellusten kehittämiseen avoimella datalla, ja millä ehdoilla mobiililaitteiden avulla voidaan saavuttaa laaja osallistuminen. Mobiililaitteet ovat jo nyt ihmisten mukana kaikkialla. Niiden ominaisuudet mahdollistavat osallistumisen paikan päällä (situated engagement) ja osallistumisen sensoridatan keräämiseen (participatory sensing) ja siten uusiin ja aiempaa monipuolisempiin käyttäjä- ja paikkalähtöisiin analyyseihin. Tämä ominaisuudet ovat olleet houkuttelevia aikaisille omaksujille. Institutionaalista tukea kuitenkin tarvitaan, että uuden teknologian mahdollisuudet voidaan tehdä tutuksi laajalle yleisölle. Mobiiliosallistuminen on myös monipuolistanut osallistumisrooleja: sen avulla kansalaiset voivat aiempaan helpommin valita mitä informaatiota saavat, esittää omia ideoitaan ja kehittää omia sovelluksia.Avoimen datan kilpailuissa kehitetyt sovellukset ovat kompromissi kehittäjien tavoitteiden ja käytössä olevan datan välillä. Kokonaisuudessaan väitöskirja esittää, että mobiiliosallistuminen on sosiaalisesti rakentunutta, siinä määrin kuin sen ominaisuudet ja käytännöt määrittyvät eri tahojen intressien yhteensovittamisessa. Tämän vuoksi mobiiliosallistuminen käsitteellistyy ”suurimmaks sallituksi poikkeamaksi”: se mahdollistaa uusia käytäntöjä jotka muokkaavat kansalaisten osallistumista samalla kun ne ovat jo osa vakiintunutta kansalaisten osallistumista

    Citizen science for observing and understanding the Earth

    Citizen Science, or the participation of non-professional scientists in a scientific project, has a long history—in many ways, the modern scientific revolution is thanks to the effort of citizen scientists. Like science itself, citizen science is influenced by technological and societal advances, such as the rapid increase in levels of education during the latter part of the twentieth century, or the very recent growth of the bidirectional social web (Web 2.0), cloud services and smartphones. These transitions have ushered in, over the past decade, a rapid growth in the involvement of many millions of people in data collection and analysis of information as part of scientific projects. This chapter provides an overview of the field of citizen science and its contribution to the observation of the Earth, often not through remote sensing but a much closer relationship with the local environment. The chapter suggests that, together with remote Earth Observations, citizen science can play a critical role in understanding and addressing local and global challenges

    EFFECTING EMPLOYEE ENERGY CONSERVATION BEHAVIOUR AT THE WORKPLACE BY UTILISING GAMIFICATION

    Get PDF
    Energy consumption is one of the widely recognised important factors that should be addressed, in reducing CO2 emissions towards addressing climate change. However, albeit the documented effect of public buildings, in specific, on energy consumption, only a limited body of research focuses on one of the most important factors that could limit it: employees’ energy consumption behaviour. Aiming to contribute to this path of research, we have identified gamification as an instrument that, when appropriately utilised, could lead to employees’ energy behaviour change. Additionally, we present a behavioural research model for employee energy conservation at work, in alignment with VBN theory of environmentalism, and a questionnaire instrument to validate it combined with practical experimentation. We consider two important categories of parameters that are connected to energy consumption behaviour in the workplace: Employees’ personal profile, which also influences the design and effectiveness of gamified apps, as well as level of environmental awareness. Concurrently, we also present preliminary findings from the analysis of the data collected after deploying the forementioned questionnaire instrument

    Economic resilience and crowdsourcing platforms

    The increased interdependence and complexity of modern societies have increased the need to involve all members of a community into solving problems. In times of great uncertainty, when communities face threats of different kinds and magnitudes, the traditional top-down approach where government provides solely for community wellbeing is no longer plausible. Crowdsourcing has emerged as an effective means of empowering communities with the potential to engage individuals in innovation, self-organization activities, informal learning, mutual support, and political action that can all lead to resilience. However, there remains limited resource on the topic. In this paper, we outline the various forms of crowdsourcing, economic and community resilience, crowdsourcing and economic resilience, and a case study of the Nepal earthquake. his article presents an exploratory perspective on the link can be found between crowdsourcing and economic resilience. It introduces and describes a framework that can be used to study the impact of crowdsourcing initiatives for economic resilience by future research. An initial a set of indicators to be used to measure the change in the level of resilience is presented.info:eu-repo/semantics/publishedVersio

    Usability of disaster apps : understanding the perspectives of the public as end-users : a dissertation presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Emergency Management at Massey University, Wellington, New Zealand

    Listed in 2020 Dean's List of Exceptional ThesesMultiple smartphone applications (apps) exist that can enhance the public’s resilience to disasters. Despite the capabilities of these apps, they can only be effective if users find them usable. Availability does not automatically translate to usability nor does it guarantee continued usage by the target users. A disaster app will be of little or no value if a user abandons it after the initial download. It is, therefore, essential to understand the users’ perspectives on the usability of disaster apps. In the context of disaster apps, usability entails providing the elements that effectively facilitate users in retrieving critical information, and thus enabling them to make decisions during crises. Establishing good usability for effective systems relies upon focussing on the user whereby technological solutions match the user’s needs and expectations. However, most studies on the usability of disaster context technologies have been conducted with emergency responders, and only a few have investigated the publics’ perspectives as end-users. This doctoral project, written within a ‘PhD-thesis-with-publication’ format, addresses this gap by investigating the usability of disaster apps through the perspectives of the public end-users. The investigation takes an explicitly perceived usability standpoint where the experiences of the end-users are prioritised. Data analysis involved user-centric information to understand the public’s context and the mechanisms of disaster app usability. A mixed methods approach incorporates the qualitative analysis of app store data of 1,405 user reviews from 58 existing disaster apps, the quantitative analysis of 271 survey responses from actual disaster app users, and the qualitative analysis of usability inquiries with 18 members of the public. Insights gathered from this doctoral project highlight that end-users do not anticipate using disaster apps frequently, which poses particular challenges. Furthermore, despite the anticipated low frequency of use, because of the life-safety association of disasters apps, end-users have an expectation that the apps can operate with adequate usability when needed. This doctoral project provides focussed outcomes that consider such user perspectives. First, an app store analysis investigating user reviews identified new usability concerns particular to disaster apps. It highlighted users’ opinion on phone resource usage and relevance of content, among others. More importantly, it defined a new usability factor, app dependability, relating to the life-safety context of disaster apps. App dependability is the degree to which users’ perceive that an app can operate dependably during critical scenarios. Second, the quantitative results from this research have contributed towards producing a usability-continuance model, highlighting the usability factors that affect end-users’ intention to keep or uninstall a disaster app. The key influences for users’ intention to keep disaster apps are: (1) users’ perceptions as to whether the app delivers its function (app utility), (2) whether it does so dependably (app dependability), and (3) whether it presents information that can be easily understood (user-interface output). Subsequently, too much focus on (4) user-interface graphics and (5) user-interface input can encourage users to uninstall apps. Third, the results from the qualitative analysis of the inquiry data provide a basis for developing guidelines for disaster app usability. In the expectation of low level of engagement with disaster app users, the guidelines list recommendations addressing information salience, cognitive load, and trust. This doctoral project provides several contributions to the body of knowledge for usability and disaster apps. It reiterates the importance of investigating the usability of technological products for disasters and showcases the value of user-centric data in understanding usability. It has investigated usability with particular attention to the end-users’ perspectives on the context of disaster apps and, thus, produces a theoretical usability-continuance model to advance disaster app usability research and usability guidelines to encourage responsible design in practice

    This is the final version. Available from Autonomy via the link in this recordWelcome to Autonomy’s ‘Platforming Equality’ document: a collection of papers on the challenges that the digital economy poses to policymakers, activists and researchers. We’ve invited a range of contributors to probe deeper into under-examined topics in the digital economy and to shed light on how they operate. Another aim of the collection is to explore policy options for alleviating a range of new challenges that have emerged within the digital economy. Contributors move beyond theoretical discussion of the problems themselves and turn towards an analysis of responses that are open to activists, municipal authorities and government policy makers. Articles suggest a range of policy recommendations and discuss the strengths and weaknesses of different approaches. Each contributor examines a specific issue based on their own research and an analysis of the existing literature. They then provide their own perspective on the policies and approaches that would be most suitable to tackling the issue

    The Case of the Mexican Mobile Government: Measurement and Examples

    Get PDF
    The mobile government has become a reality in a large majority of countries around the world. The use of apps to link government websites and information is a recent trend that is capturing citizens and public officials. The uses, advantages and disadvantages have recently become a study field for several scholars around the globe. The mobile government is not new for e-government scholars; however, the explosion of apps and the increase of smart phones have created a new trend in the mobile government field. In order to understand these phenomena in the Mexican society we have gathered data from different sources: government, companies and citizen organizations. Based on this information, we analyzed the impact of apps across the country and suggest a classification method that can be used for a better understanding of this new field. We finish with five small case studies, which we consider good examples to be followed by different government organizations. To accomplish this objective we divided this chapter into seven main sections: this first section is the introduction. The second section includes a literature review. The third section describes the method we suggest to classify the apps. The fourth section discusses the findings with the model application. The fifth section presents the case studies we suggest for government apps. The sixth section discusses future research on government apps. In the seventh section, we present some remarks and the conclusion of this topic
