Research on persuasive technologies for promoting healthy behaviours has been surging in recent years, but these technologies have the risk of being perceived as undesirable meddling. The current study puts forward a non-coercive and libertarian paternalistic alternative - the nudge theory. The foundation of the nudge theory is informed by the dual processing theory and can be categorized in two types - Type 1 nudging and Type 2 nudging. As design tools, two Type 1 nudging methods: default setting and manipulation of accessibility; and four Type 2 nudging methods: reminders, prompts, framing and precommitment strategies were selected to be featured. Sleep was chosen as the use case for this study, for it is associated with a number of non-communicable diseases yet considerably few studies of persuasive technology are about sleep. Better sleep hygiene is a significant means to improve sleep, therefore used as the design goal. The current study explores possible solutions for persuasive technologies for improving sleep hygiene, and better understand the design potentials and the persuasive characteristics of different types and methods of nudging. The research methodology is informed by scenario-based design. Five (four male and one female) academic professionals with backgrounds in interaction design, human-computer interaction, artificial intelligence and robotics took part in the study. Seven scenarios and thirteen prototypes were created to illustrate the situations and present the possible solutions. Results also showed that Type 1 nudging is considered more convenient and effective. However, the sense of control is better preserved in Type 2 nudging. In regard to nudging methods, default setting is considered as the most eective method under the condition of goal-alignment, but prone to error. Manipulation of accessibility should be designed so that the navigation is intuitive and the integrity of availability should not be damaged. Timing is the most prominent factor for reminders, and the influence of reminders could be reinforced by prioritizing and cross-platform availability. The presence of prompts could be emphasized by purposeful placement, and appropriateness should be considered. The perception of framing is highly subjective, therefore it should be user-tailored and context-aware. The effects of precommitment strategies are able to access higher-level motivation, but should be reinforced with other methods. To summarize the design principles, when designing nudges in persuasive technologies, the following factors should be considered: goal alignment, intuitiveness, context awareness, availability and accessing motivation. / Forskning inom temat persuasive teknologi för hälsoinriktade beteenden har ökat under den senaste tiden. Dock kan sådana teknologier oftast uppfattas som en oönskad inblandning i människors privata liv. Denna studie föreslår ett otvingade och libertarianskt paternalistiskt alternativ för att påverka val och beteenden – nudge teorin. Flera tidigare beprövade designverktyg betonas i denna teori. Nudge teorin har en dual process teoretisk bakgrund och kan delas in i två typer av nudging –- Typ 1 nudging och Typ 2 nudging. Bland Typ 1 verktyg väljs default setting och manipulation of accessibility, och bland Typ 2 metoder väljs reminders, prompts, framing och pre-commitment strategies. I syfte att illustrera detta användes sömn som exempel, då det har länkats till flera icke-smittsamma sjukdomar och få studier har försökt att undersöka motiverande design i relation till sömn. Bättre sömnhygien är ett betydelsefullt verktyg för att förbättra sömn och användes därför som målsättning. Denna studie undersöker möjliga alternativ för persuasive teknologi i syfte att förbättra sömn. Dessutom undersöktes potentialen av olika typer av persuasive teknologi och metoder för nudging. Den valda metodologi är en informerad scenariobaserad design. Fem akademiskt anställda, fyra män och en kvinna, med bakgrund inom interaction design, human-computer interaction, artificial intelligence och robotics, deltog i denna studie. Sju scenarion och tretton prototyper utarbetades för att illustrera en situation och presentera en möjlig lösning där sömnhygien kunde förbättras igenom persuasive teknologi. Resultaten visade att Typ 1 nudging ansågs vara mer lämpligt och effektiv. Emellertid bibehålls känslan av kontroll mer inom Typ 2 nudging. Default setting ansågs som mest effektiv inom betingelsen goal alignment, men med risk för bakslag. Manipulation of accessibility bör designas så att navigering är intuitiv och att integriteten av tillgänglighet inte störs. Tajming är den mest framträdande faktorn för reminders och deras påverkan skulle kunna framhävas igenom prioritering och cross-platform availability. Prompts skulle kunna framhävas mer igenom igenomtänkt placering där lämplighet är en drivande faktor. Uppfattningen av framing är mycket subjektiv och bör vara anpassad till användaren. Pre-commitment strategier har tillgång till högre motivation men bör förstärkas med andra medel.

En 1993, alors qu’Internet faisait ses premiers pas, le New York Times publie un dessin de presse désormais célèbre avec la légende "Sur Internet, personne ne sait que tu es un chien". C’était une façon amusante de montrer qu’Internet offre à ses usagers un espace sûr à l’abri de tout préjugé, sarcasme, ou poursuites judiciaires. C’était aussi une annonce aux internautes qu’ils sont libres de ne montrer de leurs vies privées que ce qu’ils veulent laisser voir. Les années se succèdent pour faire de cette légende une promesse caduque qui n’a pu survivre aux attraits irrésistibles d’aller en ligne. Les principales tentations sont l’anonymat et la possibilité de se créer une identité imaginée, distincte de celle de la réalité. Hélas, la propagation exponentielle des réseaux sociaux a fait chevaucher les identités réelles et fictives des gens. Les usagers ressentent un besoin d’engagement de plus en plus compulsif. L’auto-divulgation bat alors son plein à cause de l’ignorance du public des conséquences de certains comportements. Pour s’attirer l’attention, les gens recourent au partage d’informations personnelles, d’appartenance de tous genres, de vœux, de désirs, etc. Par ailleurs, l’espoir et l’angoisse les incitent aussi à communiquer leurs inquiétudes concernant leurs états de santé et leurs expériences parfois traumatisantes au détriment de la confidentialité de leurs vies privées. L’ambition et l’envie de se distinguer incitent les gens à rendre publics leurs rituels, pratiques ou évènements festifs engageant souvent d’autres individus qui n’ont pas consenti explicitement à la publication du contenu. Des adolescents qui ont grandi à l’ère numérique ont exprimé leurs désapprobations quant à la façon dont leurs parents géraient leurs vies privées lorsqu’ils étaient enfants. Leurs réactions allaient d’une légère gêne à une action de poursuite en justice. La divulgation multipartite pose problème. Les professionnels, les artistes ainsi que les activistes de tout horizon ont trouvé aux réseaux sociaux un outil incontournable et efficace pour promouvoir leurs secteurs. Le télétravail qui se propage très rapidement ces dernières années a offert aux employés le confort de travailler dans un environnement familier, ils ont alors tendance à négliger la vigilance "du bureau" exposant ainsi les intérêts de leurs employeurs au danger. Ils peuvent aussi exprimer des opinions personnelles parfois inappropriées leur causant des répercussions néfastes. L’accroissement de l’insécurité liée au manque de vigilance en ligne et à l’ignorance des usagers a mené les chercheurs a puiser dans les domaines de sociologie, des sciences de comportement et de l’économie de la vie privée pour étudier les raisons et les motivations de la divulgation. Le "nudge", comme approche d’intervention pour améliorer le bien-être d’un individu ou d’un groupe de personnes, fût une solution largement adoptée pour la préservation de la vie privée. Deux concepts ont émergé. Le premier a adopté une solution "one-sizefits-all" qui est commune à tous les utilisateurs. Quoique relativement simple à mettre en œuvre et d’une protection satisfaisante de la vie privée, elle était rigide et peu attentive aux conditions individuelles des utilisateurs. Le second a plutôt privilégié les préférences des usagers pour résoudre, même en partie, la question de personnalisation des "nudges". Ce qui a été motivant pour les utilisateurs mais nuisible à leurs confidentialités. Dans cette thèse, l’idée principale est de profiter des mérites des deux concepts en les fusionnant. J’ai procédé à l’exploration de l’économie de la vie privée. Les acteurs de ce secteur sont, autres que le propriétaire de données lui-même, le courtier qui sert d’intermédiaire et l’utilisateur de ces données. Le mécanisme d’interaction entre eux est constitué par les échanges de données comme actifs et les compensations monétaires en retour. L’équilibre de cette relation est atteint par la satisfaction de ses parties prenantes. Pour faire de bons choix, l’équitabilité exige que le propriétaire de données ait les connaissances minimales nécessaires dans le domaine et qu’il soit conscient des contraintes qu’il subit éventuellement lors de la prise de décision. A la recherche d’un utilisateur éclairé, j’ai conçu un cadre que j’ai nommé Multipriv. Il englobe les facteurs d’influence sur la perception des gens de la vie privée. J’ai ensuite proposé un système multi-agents basé sur le "nudge" pour l’atténuation de la divulgation en ligne. Son principal composant comprend trois agents. Le premier est l’agent objectif Aegis qui se réfère aux solutions généralisées axées sur la protection des données personnelles. Le second est un agent personnel qui considère le contexte dans lequel se trouve le propriétaire de données. Le dernier est un agent multipartite qui représente les personnes impliquées dans le contenu en copropriété. Pour évaluer le système, une plateforme appelée Cognicy est implémentée et déployée. Elle imite de véritables plateformes de réseaux sociaux par l’offre de la possibilité de créer un profil, publier des statuts, joindre des photos, établir des liens avec d’autres, etc. Sur une population de 150 utilisateurs, ma proposition s’est classée meilleure que l’approche de base non spécifique au contexte en termes de taux d’acceptation des "nudges". Les retours des participants à la fin de leurs sessions expriment une appréciation des explications fournies dans les "nudges" et des outils mis à leur disposition sur la plateforme. / When the internet was in its infancy in 1993, the New York Times published a now-famous cartoon with the caption “On the Internet, nobody knows you’re a dog.”. It was an amusing way to denote that the internet offers a safe space and a shelter for people to be free of assumptions and to only disclose what they want to be shown of their personal lives. The major appeal to go online was anonymity and the ability to create a whole new persona separate from real life. However, the rising popularity of social media made people’s digital and physical existences collide. Social Networking Sites (SNS) feed the need for compulsive engagement and attention-seeking behaviour. This results in self-disclosure, which is the act of sharing personal information such as hopes, aspirations, fears, thoughts, etc. These platforms are fertile grounds for oversharing health information, traumatic experiences, casual partying habits, and co-owned posts that show or mention individuals other than the sharer. The latter practice is called multiparty disclosure and it is an issue especially when the other people involved do not explicitly consent to the shared content. Adolescents who grew up in the digital age expressed disapproval of how their parents handled their privacy as children. Their reactions ranged from slight embarrassment to pursuing legal action to regain a sense of control. The repercussions of privacy disclosure extend to professional lives since many people work from home nowadays and tend to be more complacent about privacy in their familiar environment. This can be damaging to employees who lose the trust of their employers, which can result in the termination of their contracts. Even when individuals do not disclose information related to their company, their professional lives can suffer the consequences of sharing unseemly posts that should have remained private. For the purpose of addressing the issue of oversharing, many researchers have studied and investigated the reasons and motivations behind it using multiple perspectives such as economics, behavioural science, and sociology. After the popularization of nudging as an intervention approach to improve the well-being of an individual or a group of people, there was an emerging interest in applying the concept to privacy preservation. After the initial wave of non-user-specific one-size-fits-all propositions, the scope of research extended to personalized solutions that consider individual preferences. The former are privacy-focused and more straightforward to implement than their personalized counterparts but they tend to be more rigid and less considerate of individual situations. On the other hand, the latter has the potential to understand users but can end up reinforcing biases and underperforming in their privacy protection objective. The main idea of my proposition is to merge the concepts introduced by the two waves to benefit from the merits of each. Because people exist within a larger ecosystem that governs their personal information, I start by exploring the economics of privacy in which the actors are presented as the data owner (individual), broker, and data user. I explain how they interact with one another through exchanges of data as assets and monetary compensation, in return. An equilibrium can be achieved where the user is satisfied with the level of anonymity they are afforded. However, in order to achieve this, the person whose information is used as a commodity needs to be aware and make the best choices for themselves. This is not always the case because users can lack knowledge to do so or they can be susceptible to contextual biases that warp their decision-making faculty. For this reason, my next objective was to design a framework called Multipriv, which encompasses the factors that influence people’s perception of privacy. Then, I propose a multi-agent nudge-based approach for disclosure mitigation online. Its core component includes an objective agent Aegis that is inspired by privacy-focused onesize-fits-all solutions. Furthermore, a personal agent represents the user’s context-specific perception, which is different from simply relying on preferences. Finally, a multiparty agent serves to give the other people involved in the co-owned content a voice. To evaluate the system, a platform called Cognicy is implemented and deployed. It mimics real social media platforms by offering the option of creating a profile, posting status updates, attaching photos, making connections with others, etc. Based on an evaluation using 150 users, my proposition proved superior to the baseline non-context-specific approach in terms of the nudge acceptance rate. Moreover, the feedback submitted by the participants at the end of their session expressed an appreciation of the explanations provided in the nudges, the visual charts, and the tools at their disposition on the platform.

EUROPEAN TRENDS IN JUDICIAL MEDIATION AND THEIR USE IN THE CZECH REPUBLIC Abstract This dissertation deals with the phenomenon of judicial mediation. In the first part, it defines the term of mediation as such and determines its essential and additional elements. Further, the text looks into the wide spectrum of cases in which this method of alternative dispute resolution can be applied. The author specifically points out that limiting its use to family matters is rather inappropriate. The following section systematically identifies the individual types, forms and methods of mediation so that each mediation can be customized for the respective case. Finally, the first part ends with a reflection on the current issues connected to criticism of mediation. These are the enforcement of international mediated settlement agreements, the potential conflict with access to justice and the binding nature as well as enforceability of mediation clauses including their stipulation in general terms and conditions. The second part is an analysis of the use of judicial mediation in selected European countries - Italy, Germany, the Netherlands, Poland, Slovenia and Spain. Different approaches to the implementation of the mediation directive are described as well as techniques for the promotion of its use. The output of the...

Syfte och frågeställningar: Syftet med undersökningen var att identifiera vetenskapligt grundade och enkla metoder för att öka fysisk aktivitet hos befolkningen.  Första frågeställningen lyder: kan en transparent nudge riktad mot det automatiska kognitiva systemet förändra valet mellan trappa och rulltrappa?  Andra frågeställningen är följaktligen: kan en kombination av transparenta nudges riktade mot de kognitiva automatiska och reflektiva systemen förändra valet av trappa och rulltrappa? Metod: Studiedesignen var en kvasiexperimentell interventionsstudie med retrospektiv kontrollgrupp. Undersökningen genomfördes på Uppsala Centralstation där två observatörer mätte antalet trapp- och rulltrappanvändare, två morgnar per vecka i tre veckor. Under andra veckan monterades nudges på marken i form av gröna fotsteg i riktning mot trapporna och under vecka tre kompletterades dessa av affischer med motiverande budskap.  Resultat: Resultatet visar att en kombination av transparenta nudges riktade mot det automatiska respektive det reflektiva systemet, korrelerar med ökat trappanvändande. Denna undersökning fann en ökning med 1.9 procentenheter (+7.3%, p=0.048). Effekten av en nudge riktad mot endast det automatiska kognitiva systemet har däremot inte statistisk signifikans där en antydande positiv utveckling av +1.5 procentenheter (+5.7%, p=0.121) kunde observeras.  Slutsats: Slutsatsen man kan dra av denna undersökning är att nudges som riktar sig mot båda kognitiva systemen kan ge effekt och vara enkla resurser vid interventioner där syftet är att öka motivationen för fysisk aktivitet. / <p>Uppsatsen tilldelades stipendiemedel ur Överste och Fru Adolf Johnssons fond 2023.</p>

Digital nudging is a relatively new phenomenon that is increasingly mentioned and demanded in human-computer interaction. The concept originates from behavioral economics and aims to help individuals make better decisions that are beneficial to the individual as well as the society, by making subtle changes to the environment in which the decision is made. Nudging implies to pushing people in the right direction and affecting them in different types of decision making. Digital nudging aims at applying the user interface design element to guide people's decisions in digital environments. This thesis presents a study of digital nudging in the form of the six design principles in the user interface of e-commerce sites through the method cognitive walkthrough. It is based on theories of mainly digital nudging but also persuasive design and user experience with connections to psychological aspects. The conclusion of the study has shown that principles in digital nudging exists in e-stores interfaces. The study aims to develop frameworks for an alternative way of implementing digital nudging and to contribute to more knowledge in the field. / Digital nudging är ett relativt nytt fenomen som blir allt mer omtalat och efterfrågat inom människa-datorinteraktion. Begreppet har sitt ursprung från beteendeekonomi och syftar till att få individer att ta bättre beslut som är gynnsamma för den enskilda individen såväl som samhället, genom att göra subtila ändringar i den miljön där beslutet fattas. Nudging innebär att knuffa individer i rätt riktning och att på så sätt påverka individer i olika beslutsfattanden. Digital nudging avser tillämpning av designelement i användargränssnittet för att påverka människors beslutsfattande i digitala miljöer. Studien presenterar en undersökning av de sex designprinciperna inom digital nudging och hur de påträffas i e-butikers användargränssnitt genom metoden kognitiv genomgång. Undersökningen grundar sig på teorier om digital nudging och relaterad forskning som övertygande design och användarupplevelse med kopplingar till psykologiska aspekter. Slutsatsen av studien har visat att designprinciper inom digital nudging förekommer i e-butikers gränssnitt. Studien syftar till att ta fram ramverk för ett alternativt sätt att implementera digital nudging och för att bidra till mer kunskap inom området.

The aim behind this study was to observe and understand barriers to access the eHealth system equally. The study was conducted in Stockholm based on qualitative data in which semi- structured interviews were conducted among 15 interviewees from different localities of Stockholm. The findings from the collected data revealed that language barriers, lack of knowledge about digital literacy, unawareness of Swedish healthcare services, psychological and social barriers, safety and privacy concerns, and the lack of an e-identification are all major barriers to accessing the eHealth system. From the data, it has also been observed that the main causes of the aforementioned hurdles are based on varied socioeconomic levels, literacy conditions of an individual, cultural background, and age. Another important observation shows that highly qualified people with limited language abilities have a difficult time using eHealth services.

Terracotta vessels are about understanding how we can store food by using a new product solution and how we could use less energy and waste less food in doing so. This project is an attempt to minimise the energy usage in our homes but also to gain greater understanding about the food we choose to bring into our homes and what we can do to avoid throwing it away.
