Dunkels, Elza. "Bridging the distance : children’s strategies on the internet." Doctoral thesis, Umeå University, Interactive Media and Learning, 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-1340.
Full textThis thesis deals with the following questions: What do children find negative on the Internet? What counter strategies do they use? How have they developed these strategies? The method used is one-to-one online interviews and the analyses are qualitative in nature. The sample is children in grade 6 of the Swedish compulsory school, aged between 11 and 13. 104 children, 52 girls and 52 boys, from different parts of Sweden were interviewed.
The media debate seems to display consensus regarding what threats the Internet poses to young people. The conclusion of this thesis is, however, that children’s views of the Internet in many ways differ from the media related adult view. The children of this study do not express a great deal of anxiety about the negative sides of the Internet. They are aware of, and can describe many downsides but these are not present in their everyday use of the Internet. Digging deeper it turns out that many children have in fact well-developed counter strategies. However, these strategies are not conscious in the sense that the children discuss them. Instead, they seem integrated in their online environment. The counter strategies have been developed by the children alone or together with peers. In some, but remarkably few, cases adults have been giving tips or teaching the children strategies. Nevertheless, the study does not paint a picture of naïve children, unable to see actual threats, but of responsible young citizens who are aware of the threats that exist in their online setting – sometimes from personal experience – and have developed methods to avoid such threats.

Digital Thread is a data-driven architecture that links together information generated from across the product lifecycle. Though Digital Thread is gaining traction as a digital communication framework to streamline design, manufacturing, and operational processes in order to more efficiently design, build and maintain engineering products, a principled and unified formulation of the data-driven design problem using Digital Thread remains absent in the literature. Prior work on Digital Thread has targeted enterprise level risk/value assessments, addressing upcoming challenges and future visions, and establishing requirements from the vantage point of model-based systems engineering, product lifecycle management, and additive manufacturing. However, such a formulation must account for the fact that the design process is highly iterative and not all information is available at once.
Design decisions must be made not only on what data to collect but also on the costs and benefits involved to collect those data. Furthermore, since full use of acquired information can become computationally prohibitive, it is important to evaluate what minimal information is sufficient for design decisions and in what form that information is needed. The contribution of this thesis is to present such a formulation from the context of a data-driven design and decision problem under uncertainty. In particular, we lay down a mathematical foundation for Digital Thread and develop an dynamical feedback process model that governs the mechanics of the data-driven design problem that uses Digital Thread. From this model, we construct a Bayesian filter that describes the overall data assimilation process and formulate a multistage optimization problem that produces optimal data-informed decisions with respect to specified cost and constraint metrics.
A numerical approach based on function and policy approximation is detailed and an algorithm is provided to solve the multistage optimization problem. The overall methodology is illustrated on an example structural fiber-steered composite component. In this setting, the methodology enables design space explorations that assess the costs/benefits of future outcomes based on current design decisions. These design decisions can incorporate structural tailoring, sensor placement, and sensor selection in addition to fiber angle and thickness specification. Different design scenarios utilizing sensor placement and selection are compared and quantified. It is found that placement of sensors has less impact on cost than the choice of which sensors are used and how frequently. Accordingly, this method is able to assess how many sensors need to be used to resolve the dominant loading components effectively, and then use this knowledge to produce appropriate designs of low costs.

The manufacturing sector is on a precipice to disruptive change that will signifcantly alter the way industrial organizations think, communicate, and interact. Industry has been chasing the dream of integrating and linking data across the product lifecycle and enterprises for decades. However, inexpensive and easy to implement technologies to integrate the people, processes, and things across various enterprises are still not available to the entire value stream. Industry needs technologies that use cyber-physical infrastructures efectively and efciently to collect and analyze data and information across an enterprise instead of a single domain of expertise. Meeting key technical needs would save over $100 billion annually in emerging advanced manufacturing sectors in the US. By enabling a systems-thinking approach, signifcant economic opportunities can be achieved through an industrial shift from paper-based processes to a digitally enabled model-based enterprise via the digital thread. The novel contribution of this dissertation is a verifed and validated integration framework, using trusted linked-data, that brings all phases and systems of the product lifecycle together. A technology agnostic approach was pursued for dynamically generating links. A demonstration is presented as a reference implementation using currently available technology. Requirements, models, and policies were explored for enabling product-data trustworthiness. All methods were developed around open, consensus-based standards to increase the likelihood of scalability. The expected outcome of this work is efcient and efective measurements of the lifecycle to support data-driven methods, specifcally related to knowledge building, decision support, requirements management, and control of the entire product lifecycle.

Full textEsta dissertação tem como objetivo avaliar qual a tendência da indústria fonográfica nos próximos anos, tendo em vista as mudanças estruturais que ela vêm passando em conseqüência das alterações ocorridas no ambiente. O setor vem sendo drasticamente abalado por uma oferta ilegal de produtos, além de inovações tecnológicas que podem ser utilizadas de forma benéfica, mas também possibilitam um acesso incontrolável à principal matéria prima das gravadoras. A metodologia utilizada para buscar esta tendência foi o método Delfos de previsão. Este método foi o escolhido por se tratar de um setor desprovido de um histórico confiável, devido às constantes mudanças tecnológicas e de padrão de consumo, e dos eventos atuais que provocam a insegurança sobre o futuro da indústria proporcionarem alterações inesperadas. O método permite a elaboração de uma previsão com base na opinião de especialistas, e tem como resultado uma avaliação do futuro da indústria com base na percepção de pessoas diretamente ligadas a ela. Através deste estudo foi possível verificar que existe uma expectativa de que o governo vá se posicionar mais fortemente com relação à repressão da pirataria musical e que as gravadoras eventualmente passem a tratar como negócio não só a produção de CDs, mas também outros produtos e serviços diretamente ligados à música. Também foi possível concluir que a música digital, de forma geral, não é percebida como uma ameaça à indústria de música tradicional, e pode ser vista como uma oportunidade de negócio. Assim, foi possível diagnosticar o futuro mais provável para as empresas e a estrutura do setor fonográfico brasileiro, além de verificar as variáveis que indicarão a formação deste cenário.
The present work intends to evaluate the most probable scenario for the Brazilian phonographic industry in the next few years, taking in account the structural changes that have been going on in the environment. This industry has been suffering from the continuous increase on the illegal products offering, in addition to new technological solutions, which may have positive implications, but may also allow innovative and uncontrollable ways of obtaining the recording companies´ main asset without paying for it. The Delfos technique has been the methodology chosen for this study. The method was the best choice bearing in mind that the industry does not have a trustworthy historical data, partially because of the technological innovation and chances on the consumption pattern, and the current events on the sector had resulted on unexpected turn a rounds on the industry´s development. Trough this work it has become possible to identify that it is expected from the government to take stronger measures to reprehend the music piracy and also that the recording organizations will eventually make their ways not only with CDs themselves but also with everything music related. Besides, digital music is not perceived as a threat, but in fact is expected to become a business and distribution opportunity for the music industry. Therefore, it has been possible to forecast the most likely future for the companies on the Brazilian music business, along with defining the variables that will indicate the structuring of this scenario.

Thanks to today's digital imaging technology, any ten year old child with basic computer skills can create convincing counterfeit currency. It comes as no surprise that as output quality and costs have improved in ink-jet printers, there has been a corresponding surge in digital counterfeiting of security documents. The design of a system, through which a printer can recognize a security or other protected document though identification of a watermark, presents a challenge for the application of information hiding techniques. The marking should be strong enough to provide certainty that a document was intentionally marked and robust enough to withstand the transformations inherent in the scanning and printing process. Using an extended spreadspectrum technique, a small one-dimensional thread encoded with a known multi-bit signature is generated. If the printer detects a match, printing halts and a warning message is output to the user. By applying several such threads at varying orientations, this can provide an effective first line of defense against the casual digital counterfeiter.

Full textThreat recognition and geographical training are fundamental parts of the requisite knowledge base for a large number of naval personnel who are assigned to operational or operations-oriented support billets. Yet readiness in these areas is often lacking, in large part due to the paucity of readily available, motivational instruction tools. This thesis explores major issues involved in integrating two emerging technologies, hypermedia and digital optical media (DOM), in the context of developing a prototype of just such an application: the GEOgraphic and Threat RECognition (GEOTREC) training and reference tool. The hypermedia software package used to develop the GEOTREC prototype, Hyperdoc version 1.12, gives evidence of the maturation yet needed in the integration of hypermedia and DOM technologies in application authoring tools. This thesis recommends the development of a system at least somewhat analogous to the GEOTREC prototype. Such a tool, using both hypermedia and DOM, would not only provide an enjoyable, intuitive, yet challenging way to foster multi-sensory learning, but also a quick, powerful, and easy-to-use reference to geographical and threat information needed for a myriad of operational scenarios.

New tree measurement techniques have been developed to improve the precision and quality of the dendrometric measurements performed. Among them the LIDAR technology stands out through which it is possible to obtain high precision three-dimensional data. Thereby the general objective of this work was to evaluate the use of the LIDAR ALS (Airborne Laser Scanner) and of the TLS (Terrestrial Laser Scanner) technologies for obtaining the dendrometric variables in commercial planting of Pinus taeda. The study area was a 16 years old plot without silvicultural treatment located in Doutor Pedrinho – North of the SC State, inside the Cerro Azul Farm owned by the Valor Florestal Company. A circular plot with 400 square meters was selected for the study. All the trees were numbered, marked and the DBHs and 10% of the heights were measured. The TLS data was obtained on the field with the Leica Scanstation P40 equipment on five different sweep positions to assure that all the shafting were covered by LASER points. The parcel was also georeferenced and points were taken from its inside with the total station equipment. The ALS points cloud data was supplied by EMBRAPA FLORESTAS and was collected in a flight performed on Jan, 2014. The 4 chapters of this dissertation demonstrates the ALS and TLS technologies state of the art in the forestry field (chapter 1); different filters were tested for obtaining the DTM from the ALS data and compared with the total station data where the ATIN filter presented the best results (chapter 2); segmentation and delineation of the treetops from the ALS cloud and automatic identification of the tree trunks in the TLS cloud in which the lack of thinning and silvicultural treatment had a negative impact on the results (chapter 3); and on chapter 4, the comparison of the dendrometric variables obtained through the ALS and TLS technologies with the heights and volume modeling obtained on the field presented statistic differences through the Dunnett statistic test (α = 5%) when compared with the ALS data for total height and the TLS for DBH and volume Lastly it is given a general conclusion about the theme explored in the dissertation with recommendations for future work

A área de estudo, um talhão de 16 anos de idade sem tratos silviculturais, localizada em Doutor Pedrinho – SC, norte do estado, na Fazenda Cerro Azul, pertencente a empresa Valor Florestal. Foi selecionada uma parcela circular, de área igual a 400 m² foi instalada para realização dos estudos. Todas as árvores foram numeradas, marcadas e mensurados os DAPs e 10% das alturas foram medidas. Os dados TLS foram obtidos em campo com o equipamento Leica Scanstation P40 em cinco diferentes posições de varredura para garantir que todos os fustes fossem recobertos por pontos LASER. A parcela também foi georreferenciada e tomados pontos com estação total no seu interior. A nuvem de pontos ALS foi fornecida pela EMBRAPA FLORESTAS em um voo realizado em janeiro de 2014. No decorrer dos 4 capítulos desta dissertação foi demonstrado o estado da arte das tecnologias ALS e TLS na área florestal (capítulo 1); testados diferentes filtros para obtenção do MDT a partir dos dados ALS, comparados com os dados de estação total, no qual o filtro ATIN demonstrou os melhores resultados (capítulo 2); segmentação e delineamento das copas a partir da nuvem ALS e identificação automática de troncos na nuvem TLS, no qual a falta de desbastes e tratos silviculturais influenciou negativamente nos resultados (capítulo 3); e no capítulo 4 a comparação entre as variáveis dendrométricas obtidas pelo ALS e TLS com as modelagens de altura e volume obtidas em campo, na qual foi constatada diferenças estatísticas com os dados ALS para altura total e com os dados TLS para DAP e Volume por meio do teste estatístico de Dunnett, α = 5%. Por fim é dada uma conclusão geral acerca do tema explorado na dissertação, com recomendações para os trabalhos futuros

Full textThe development of the latest information technologies and the digitalization of the national economy are accompanied by an increase in cybercrime and losses from information leaks. Thus, the creation of a reliable information security system at all levels of management of the national economy is required to prevent various kinds of cyber threats and stimulate its development. This research was aimed at solving such issues as substantiating the essence and role of information security in the national economy, developing an assessment methodology and determining its place in ensuring the national economic development, establishing cause-and-effect relationships in studying the impact of information security on the balance of the national economy, developing applied methodological tools for increasing the information security. The suggested concept of “information security”, taking into account its multi-component and dynamism, made it possible to form the concept of its provision in the national economy management system, which formalizes threats as prerequisites for violating the integrity, confidentiality, and availability of information security objects, defines the agents, means, and mechanisms of control. The bibliometric analysis of scientific papers allows determining the relevance of information security issues and defining the dominant vectors of its research in the context of economic areas. The use of canonical analysis for a group of indicators of the digital capacity of the national economy and cybersecurity and seven groups of indicators characterizing the economic, social and financial development of the national economy, foreign economic activity, innovative activity, the quality of information infrastructure and the institutional capacity of the state revealed that the digital national economic and cybersecurity capabilities and institutional capacity have the most significant mutual influence. These results contributed to the development of an integral index of information security of the national economy using the method of advantages and the Harrington-Mencher function and to create a rating of the countries according to them. It turned out that Ukraine has a satisfactory level of information security of the national economy. The clustering of countries through constructing self-organizing maps was carried out, and the analysis of the comparative effectiveness of the components of the information security system of the national economy using the DEA analysis revealed the structural inefficiency of the sub-indices of the integral index of the information security of the national economy to ensure its maximum level. For Ukraine, the value of its effectiveness is 63.7%, which is a consequence of the inefficiency of institutional capacity indicators. Their improvement from 8.91% to 88.57% will ensure the maximum increase in the efficiency of information security of the national economy by 57.04%. The cluster analysis confirmed an influence of measures of public authorities on the consequences of cyber incidents and dependencies between the level of well-being, national social traditions, mental and cultural characteristics of the country, and personal security measures that are preferred by the population of European countries. Gravity modeling was used to prove that the level of their information security affects the level of attractiveness of countries for money laundering. The results provided a list of countries for which Ukraine is the most attractive in terms of money laundering. This step will improve regulatory policy and promote the convergence of cybersecurity and state financial monitoring systems. The results of modeling information activities using the Sedva-Taylor model have proven the existence of destabilizing effects of the information environment on the national economy, which will allow timely identification of signs of collapse in its various sectors. Multiple attribute decision making was used to found that the most critical targets of information security for Ukraine are the system of analysis and information about cyber threats, cyber crisis management, Ukraine’s activities regarding its contribution to global cybersecurity, and the organization of military cyber operations. The justification of the priorities for the formation of state sectoral and industrial programs towards ensuring the information security of the national economy made it possible to identify enterprises that are most vulnerable to the consequences of cyber threats and to establish an economically feasible limit range of costs for information security. The methodology for constructing a four-pole barycentric model allows determining the level of balance between economic, political, social development and the development of digital capabilities and cybersecurity of countries. Ukraine was found to be an outsider among unbalanced countries, for which the most promising factor is a composite indicator of digital capability and cybersecurity. To ensure the development of applied methodological tools for increasing information security, methods are proposed for express assessment of the risks of information and data loss, which can be used to determine the probable catalysts of incidents, taking into account the frequency of their recurrence and the monetary assessment of damage from loss of information, regardless of the information security subjects. The developed method of system dynamics modeling allows substantiating the processes of rebuilding security systems, and its testing for blockchain technology showed its efficiency. The proposed methodology for creating an applied three-tier system for preventing financial and cyber threats allows identifying “bottlenecks” in the protection system that cause uncontrolled information leakage or cybercriminals’ interference; identify the agents of operations according to various criteria corresponding to the elements of cybercrimes; identify operations based on cybercrime elements. The methods tested on financial sector data have helped prevent financial and cyber threats.

Technological development has significantly improved the flow and the use of information, bringing our present lives more conveniences and systems to manage operational efficiency. However, information technology has also brought negative effects for individuals. It has spurred the public and private sectors ability to deeply track our daily activities, possibly revealing the most intimate of details. With electronic monitoring, frequent tracking and information systems becoming more massive in scale, privacy is threatened. This article will be divided into six chapters. The first chapter is the introduction. The second chapter is the development of the concept of privacy. The 2nd chapter discusses the historical development of privacy rights in United States and Taiwan. The value of privacy must be understood through social and cultural context. The second chapter will examine public authorities that are using technology in criminal investigations and its use in trials, detailing possible privacy threat implications. A discussion will examine the public authority’s electronic monitoring and tracking of people and its related privacy issues. When the majority of domestic literature only addresses the U.S. Department of Homeland Security’s establishment of several large-scale information systems, this paper will address the local case that has originated in the past two years concerning Taiwan’s New Taipei City "Defense Science and Technology City" program and its content. While integrating information systems and constructing policing technology and management systems, we will scrutinize how there is a lack of consideration in the corresponding planning for privacy. The third chapter will cover surveillance in the workplace and its threat to privacy. The employers justify their electronic monitoring and tracking with "Electronic Performance Monitoring", "Enterprise Confidential", "Employees’ Consent" reasoning. This reasoning has been resulting in a dilemma for privacy. The fifth chapter investigates consumer privacy protection in a network information society. Industry provides free services, and in exchange, the user provides relevant personal information on friendships, interests and activities. The industry, then using this information, attracts advertisers, application developers and other commercial entities that see opportunities. Access to large-scale personal information has been so simple in recent years. This chapter, examines how data mining is now commonly used "marketing approach" and discuses the collection, processing, and its using of the three stages respectively for what privacy issues may encounter. Last, chapter six will conlcude.

Since 1980, the government has actively invested in the development of the biotechnology industry. After more than 30 years of development, the current performance is not only lagging behind the advanced countries in the world, but also at a relative disadvantage in facing major Asian competitors. In today’s digital era, many industries’ development models and competition rules have been substantially revised. When thinking about the future of industrial development, the impact of digital technology will be either dominant or disadvantageous. This study aims to explore the current state of development of the biotechnology and medical industry in various countries, and then analyzes the changes in science and technology and the evolution of medical theory in the digital era. The study found the following four points: 1. Taiwan's development in the traditional biotechnology and medical industries (new drugs, vaccines) is currently lagging behind; 2. The medical industry in the digital age has caused tremendous changes in the industrial structure due to the introduction of a large number of digital technologies. 3. Medical theory changes due to the development of quantum mechanics, many attempts have been made to think medically from the perspective of physics. The preliminary results are surprising; 4. Taiwan’s existing industry advantage in the international arena is the information and communication technology industry, among which the leader is the semiconductor industry. Based on the above observations, this study concludes with a possible development strategy for the biotech medical industry as a reference.

It is Extremely rapid development of cloud computing applications . Each cloud service providers have been developed numbers of applications and services in recent years. However, cloud computing is a new generation of technology transfer developed from internet. It is not only having the characteristics of the network but also inherited its weaknesses. Especially virtualization, regulations, data privacy, and other issues further make digital forensics work difficult. The purpose of this study was to correspond the four-oriented from digital evidence forensics standard operate procedure (DEFSOP) which published by domestic scholars Professor Lin Yi long for 24 security risks proposed by the European Network and Information Security Agency(ENISA), and comprehensive various cloud threat corresponding tools, strategies to discussion of the risk assessment of the security of cloud service. Furthermore, based on the above theoretical to propose Integrative Digital Evidence Forensics Standard Operate Procedure for Cloud Threats (I-DEFSOP) to solve the problems faced by the cloud forensics. Finally, verifying the I-DEFSOP’s integrity, reliability and validity by the Delphi expert survey.

Full textInformations- och kommunikationsteknik (IKT) har under de senaste årtiondena varit under stark utveckling. Ökad tillgänglighet av mobil teknik, såsom smarta mobiltelefoner och andra bärbara enheter med inbyggda sensorer, kraftig utbyggnad av kommunikationsinfrastruktur samt framsteg inom spektrumeffektivitet, har haft en stor betydelse för civilsamhället samt i ökande grad även för insatsorganisationer såsom Försvarsmakten. Tekniken bidrar till ökad förmåga till ledning, situationsuppfattning och informationshantering, men medför samtidigt flera utmaningar inom områden som cybersäkerhet och personlig integritet. Nya uppgifter som parallellt kommit i fokus för försvarsmakter i många länder inkluderar förmågan att kunna delta i stödjande insatser i samband med naturkatastrofer, terrorattacker, eller att kunna erbjuda humanitärt bistånd i internationella miljöer. Sådana insatser kräver vanligtvis samverkan mellan många olika heterogena organisationer, vilket medför ett behov av såväl teknisk som organisatorisk interoperabilitet. Viss information måste kunna delas effektivt mellan de ingående aktörerna med avseende på riktighet och tillgänglighet, samtidigt som känsliga uppgifter måste skyddas avseende sekretess. I denna avhandling studeras taktiskt användande av framväxande IKT på morgondagens slagfält, hur tekniken kan bidra till mer effektiva operationer, samt vilka förutsättningar och krav som måste uppfyllas för att tekniken ska kunna vara till nytta vid interorganisatorisk samverkan. Särskilt undersöks möjligheten att upprätthålla en acceptabel nivå av informationssäkerhet i gemensamma taktiska sambandssystem, samtidigt som dessa kan användas effektivt under påfrestande förhållanden. Avhandlingen finner att tekniker som mobila ad hoc-nätverk, mjukvarudefinierad radio och kognitiv radio, trots att de ännu är omogna, kan komma att bidra till förbättrade eller helt nya förmågor inom bland annat samband, ledning och informationsinhämtning. Vidare dras slutsatsen att ramverket Hastily Formed Networks är effektivt för samverkan mellan heterogena aktörer. För att framväxande IKT ska kunna vara av militär nytta krävs dock att flera icke-tekniska krav kan mötas. Dessa inkluderar användbarhet, tillit, legalitet, kostnad, samt att tekniken ligger i linje med rådande militär doktrin. Såväl antagonistiska som oavsiktliga hot måste samtidigt hanteras, såsom informationsläckor orsakade av cyberattacker eller insiders, samt konsekvensen av en minskad personlig integritet för användarna. Avhandlingen förväntas vara av intresse för såväl Försvarsmakten som organisationer med liknande förutsättningar i Sverige och jämförbara länder. Som slutsats rekommenderas i avhandlingen att framväxande IKT till stöd för nya förmågor kontinuerligt utvärderas genom såväl akademisk forskning som intern konceptutveckling, samt att en inkrementell och modulär modell bör väljas vid utveckling och anskaffning, snarare än att göra omfattande investeringar i proprietär teknik. Fokus bör även vara på att tidigt få med militära krav i civila IKT-standarder. På så vis kan utvecklingskostnader reduceras, samtidigt som militär användning av kommersiellt tillgängliga produkter förenklas. En slutsats gällande informationssäkerhet är att man med metoder som baseras på så kallad ”best-effort” kan effektivisera utbytet i ett gemensamt informationssystem, samtidigt som risken för dataläckage kan behållas på en acceptabel nivå.

Find full textHow does collective action operate in digital space, particularly for those social movements at the cutting edge of technologically innovative contentious politics? This dissertation analyzes activist (and hacktivist) groups engaged in what I call digital contention with state and corporate institutions over the future of Internet policy and governance, or what they see as “the freedom of the Internet.” Based on case studies of the Digital Rights movement and the Anonymous hacktivist collective, I use a combination of computational and qualitative analyses of online texts, along with participant-observation at meetings and protest events, to explore how certain collective action dynamics are changing in digital space. Specifically, these include how movements internally perceive political opportunities and threats, as well as how they construct frames to communicate to external audiences. I find that: 1) Political opportunity is less important than threat for activists in digital contention, which is likely due to the lower costs of collective action; and 2) The digital divide and technological knowledge gap create a barrier to frame resonance which digital activists address either through “strategic inclusiveness” or “communities of anonymity,” both of which encourage diversity among participants while also reifying other inequalities in different ways. These findings have significance for the study of social movements, communication and technology studies, and Internet policy. I argue that they portend changing dynamics that may ultimately affect all forms of collective action, and indeed the balance of power in whole societies, in the future as digital technology continues to spread into every facet of our lives.

Full textInspiriert von den enormen technologischen Fortschritten der letzten Jahrzehnte beschäftigt sich die vorliegende Dissertation mit der Wahrnehmung emotionssensitiver künstlicher Intelligenz (KI) und nimmt dabei vor allem die Bedeutung von erlebter Menschenhaftigkeit in den Fokus. Bei der Entwicklung meiner Hypothesen finden Befunde von kognitionswissenschaftlichen Studien ebenso Beachtung wie philosophische und kulturpsychologische Literatur. Tatsächlich gipfelt die interdisziplinäre Recherche in einer deutlichen Vermutung: Da das Erkennen von Geistes- und Gefühlszuständen in anderen Lebewesen von vielen Personen als Kernkomponente ihrer menschlichen Einzigartigkeit betrachtet wird, laufen affektive Technologien mit ähnlichen Fähigkeiten Gefahr, unheimlich oder abstoßend zu wirken – sie werden zu unliebsamen ‚Eroberern‘ einer urmenschlichen Domäne. In einer ersten empirischen Studie (N = 92) finde ich Hinweise auf die Gültigkeit der getroffenen Annahme. Es zeigt sich, dass empathisch agierende Figuren in einer virtuellen Umgebung deutlich stärkere Ablehnung hervorrufen, wenn Probanden dahinter keine Menschen (Avatare), sondern ein hochkomplexes KI-System (autonome Agenten) vermuten. Nachdem persönliche Beobachtungen und Aussagen der Versuchspersonen wiederholt auf die Rolle von Bedrohungswahrnehmnungen hindeuten, stelle ich diese Variable ins Zentrum einer zweiten Untersuchung. Mithilfe vertiefender Literaturrecherche entwickle ich ein „Model of Autonomous Technology Threat“ („Modell der Bedrohung durch autonome Technologie“), welches zwei potentielle Determinanten von Technologieaversion kombiniert: Während die distale Facette übergeordnete Einstellungen zu menschlicher Einzigartigkeit bündelt, wird zudem ein starker Einfluss von unmittelbaren (proximalen) Wahrnehmungen postuliert, etwa dem erlebten Ausmaß an situativer Kontrolle oder der Sorge um die eigene physische Unversehrtheit. Ein neues Virtual-Reality-Experiment, in dem Probanden (N = 125) mit einem angeblich autonomen – tatsächlich jedoch ferngesteuerten – Agenten interagieren, dient dazu, das Modell statistisch zu überprüfen. Obgleich sich durchaus Hinweise zur Bedeutsamkeit des distalen Pfades abzeichnen, erweisen sich vor allem proximale Faktoren als signifikanter Prädiktor von Bedrohungsempfinden und infolgedessen der Nutzerakzeptanz. Mit einer dritten Studie soll schließlich exploriert werden, inwieweit die Wahrnehmung von Menschenartigkeit auch bei nicht verkörperlichten, emotionssensitiven KIs Relevanz besitzt. Zugleich rücke ich nun Kultureinflüsse in den Fokus, indem ich Versuchspersonen verschiedener kultureller Herkunft (N = 89) eine automatisierte Emotionserkennungssoftware kennenlernen lasse. Während chinesische Probanden, deren kulturelle Sozialisation tendenziell ein breiteres Verständnis von ‚Beseeltheit‘ umfasst, nur kurzzeitig vom Feedback der affektiven Software in Erregung versetzt werden, lässt sich bei deutschen Versuchspersonen ein deutlich längerer Anstieg physiologischer Aktivierung feststellen. Zugleich zeichnet die Messung subjektiver Empfindungen ein überraschendes Bild: Die emotionssensitive Maschine – in diesem Fall ein abstrakter, mechanischer Kasten – wird umso positiver bewertet, je mehr Menschenhaftigkeit Probanden in ihr erkennen. Angesichts der drei durchgeführten Studien komme ich zu dem Schluss, dass lediglich Szenarien mit verkörperlichter KI im Sinne des entwickelten Bedrohungsmodells beide Pfade bedienen, was für eine eindeutig aversive Reaktion erforderlich sein könnte. Die Gestaltung der Software in Studie 3 spielte unterdessen für das unmittelbare Kontrollerleben der Versuchspersonen keine Rolle; eine mögliche Erklärung, warum sich Attributionen von Menschenähnlichkeit hier sogar positiv in den subjektiven Evaluationen niederschlugen.
