The Impact of Web Accessibility Overlays on the Usability and User Experience for People with Permanent Visual Impairments / Die Auswirkung von Accessibility Overlays auf die Benutzungsfreundlichkeit und Nutzungserfahrung von Menschen mit Permanenten Visuellen Beeinträchtigungen

Kubesch, Daniela January 2024 (has links)
Today, the internet connects 66.2% of the world’s population online. Accessibility to digital information is crucial for social inclusion and equal opportunities. In this respect, it is considered to be a fundamental human right. However, most websites contain accessibility errors, creating a significant barrier for users with impairments. Accessibility overlays have emerged as potential solutions to enhance web accessibility. They often appear on a website as a toolbar or widget and allow users to customise their browsing experience by offering various adjustments, such as changes to font size, colour contrast, and text-to-speech functionalities via a button click. Some accessibility overlays use Artificial Intelligence (AI) to identify and automatically correct accessibility errors in website code. However, despite their intended benefits and rapid market growth, accessibility overlays face significant criticism within the accessibility community due to concerns about their effectiveness and whether they meet the needs of the intended user group.  This thesis investigates the impact of accessibility overlays on the usability and user experience (UX) for individuals with permanent visual impairments, thereby addressing a gap in academic research. Given the rise in visual impairments due to population growth and ageing, this focus is relevant and timely. The conducted research involved an evaluation study that comprised two parts: a technical evaluation of accessibility overlays against the Web Content Accessibility Guidelines (WCAG) 2.1 standard, and a user study that assessed the usability and UX of 21 individuals with permanent visual impairments when interacting with websites that employ an accessibility overlay. Furthermore, interviews with two accessibility consultants and two accessibility overlay company representatives provided supplementary information to the discussion.  The research shows that accessibility overlays, in their current form, do not effectively improve the usability or UX for individuals with permanent visual impairments. Although there is a slight improvement when users are unaware of the overlay’s presence, overall, UX and usability are considered marginal at best and deteriorate upon recognition and interaction with an accessibility overlay. Furthermore, the research displays that accessibility overlays in their current form cannot meet WCAG 2.1 AA standards. The study also finds that users with permanent visual impairments are generally hesitant to engage with accessibility overlays and prefer to rely on their existing access technologies. However, they are willing to use accessibility overlays under improved conditions, which are discussed in the thesis. The empirical knowledge gained guides future technology, designs, policies, and research to create a more inclusive digital world. / Heutzutage sind 66,2% der Weltbevölkerung über das Internet miteinander verbunden. Der Zugang zu digitalen Informationen ist ein fundamentales Menschenrecht, das soziale Inklusion und Chancengleichheit fördert. Jedoch weisen die meisten Webseiten Barrierefreiheitsfehler auf, die für Nutzer*innen mit Beeinträchtigungen eine erhebliche Hürde darstellen. Als potenzielle Lösungen für verbesserte Zugänglichkeit sind sogenannte "Accessibility Overlays" entstanden. Sie werden oft als Symbolleiste oder Widget auf einer Webseite angezeigt und ermöglichen es Nutzer*innen, ihr Navigationserlebnis durch verschiedene Anpassungen, wie zum Beispiel Änderungen der Schriftgröße oder des Farbkontrastes, per Mausklick, anzupassen. Einige Overlays nutzen außerdem Künstliche Intelligenz (KI), um Barrierefreiheitsfehler im Webseiten-Code zu erkennen und automatisch zu korrigieren. Obwohl Accessibility Overlays Barrierefreiheit und Zugänglichkeit beabsichtigen, werden sie von Teilen der Barrierefreiheits-Community aufgrund von Bedenken hinsichtlich ihrer Effektivität und Zielsetzung stark kritisiert.  Diese Masterarbeit untersucht die Auswirkungen von Accessibility-Overlays auf die Benutzungsfreundlichkeit und Nutzungserfahrung von Menschen mit dauerhafter Sehbeeinträchtigung. Die Arbeit adressiert damit eine existierende Lücke in der akademischen Forschung. Da etwa 4,3% der Weltbevölkerung eine visuelle Beeinträchtigung haben und diese Zahl aufgrund von Bevölkerungswachstum und -alterung weiter ansteigt, ist dieser Schwerpunkt relevant und zeitgemäß. Die durchgeführte Forschung umfasst eine Evaluierungsstudie, die in zwei Teile gegliedert ist: eine technische Evaluierung von Accessibility-Overlays anhand der Web Content Accessibility Guidelines (WCAG) 2.1 und eine Nutzer*innen-Studie, die Benutzungsfreundlichkeit und Nutzungserfahrung von 21 Personen mit dauerhaften Sehbeeinträchtigungen bei der Interaktion mit Webseiten, die ein Accessibility Overlay integriert haben, bewertet. Zusätzlich liefern Interviews mit zwei Berater*innen für Barrierefreiheit und zwei Unternehmensvertretern von Accessibility Overlays einen ergänzenden Beitrag zur Diskussion.  Die Ergebnisse zeigen, dass Accessibility Overlays in ihrer derzeitigen Form die Benutzungsfreundlichkeit und Nutzungserfahrung für Personen mit dauerhaften Sehbeeinträchtigungen nicht signifikant verbessern. Obwohl eine leichte Verbesserung eintritt, wenn Benutzer*innen sich der Existenz eines Overlays nicht bewusst sind, wird die Nutzungserfahrung und Benutzungsfreundlichkeit insgesamt bestenfalls als marginal angesehen und verschlechtert sich, sobald ein Overlay erkannt und damit interagiert wird. Darüber hinaus zeigt die Forschung, dass Accessibility Overlays die WCAG 2.1 AA-Standards aktuell nicht erfüllen können. Die Studie kommt auch zu dem Ergebnis, dass Nutzer*innen generell zögern, sich auf Accessibility Overlays einzulassen und es vorziehen, sich auf ihre vorhandenen Zugangstechnologien zu verlassen. Allerdings sind die Nutzer*innen bereit, eine potenziell verbesserte Version von Accessibility Overlays zu nutzen, wie sie in dieser Masterarbeit abschließend diskutiert wird. Das gewonnene empirische Wissen dient als Orientierungshilfe für zukünftige Technologien, Designs, Richtlinien und Forschungsarbeiten, die darauf abzielen, eine inklusivere digitale Welt zu kreieren. / <p>This thesis was also submitted to the Master degree program MultiMediaTechnology at the Salzburg University of Applied Sciences, in fulfilment of the requirements for the double degree program with Halmstad University. </p>

Digitala leveranskedjor och höga krav på informationssäkerhet : Implikationer för att stärka Sveriges digitala motståndskraft / Digital supply chains and high requirements for information security : Implications for strengthening Sweden's digital resilience

Dohrendorf, Christian January 2024 (has links)
Syftet med uppsatsen är att öka kunskapen kring organisationers och kringliggande aktörers förmåga att stärka den digitala motståndskraften i digitala leveranskedjor genom införande av ett omfattande regelverk. Uppsatsen beskriver hur tillkommande regelverk med höga krav på informationssäkerhet inom de digitala leveranskedjorna påverkar en enskild organisation. Uppsatsen beskriver även implikationerna ur ett övergripande systemperspektiv. Utifrån införandet av Digital Operational Resilience Act (DORA) beskrivs både potentiella hinder som riskerar hämma Sveriges digitala motståndskraft och de möjliggörande åtgärder som leder till att Sveriges digitala motståndskraft stärks. Uppsatsen identifierar genom en fallstudie ett antal hinder som enskilda organisationer bör beakta, men som även har stora beroenden till andra kringliggande aktörer och systemet i sin helhet. Uppsatsen beskriver att det kan uppstå följdeffekter som lätt leder till oönskade effekter. Komplexitetshöjningen genom tillkommande regelverk kräver medvetna handlingar av ett stort antal aktörer för att undvika att hinder blir alltför hämmande och därmed hindrande för Sveriges digitala motståndskraft. Speciellt mindre leverantörers situation lyfts som problematisk i sammanhanget. Uppsatsen identifierar behovet av en holistisk inställning som nödvändig för att kunna skapa utrymme för medvetna handlingar. Komplexitetshöjningen som tillkommande regelverk innebär behöver hanteras både internt inom en enskild organisation och genom externa samarbeten. Uppsatsen beskriver att identifierade möjliggörande åtgärder inte enbart bör värderas utifrån direkta effekter, utan även utifrån mer långsiktiga indirekta effekter och resurspåverkan i systemet. Först då finns det förutsättningar att genom medvetna handlingar uppnå positiv effekt och därmed stärka Sveriges digitala motståndskraft.

Technology In Policing : An ethnographic study of the use of information and communication technology within Bedfordshire police force

Kazeem, Ganiat Omolara January 2018 (has links)
Policing in The United Kingdom is an intricate business, balancing the enforcement of statute and other laws while dealing with public safety and security. Policing engages a diverse and complicated set of organisational structures and processes relying heavily on the skill and expertise of officers on the ground. Their role in preventing and or intercepting crime before, during and after it occurs is integral to sustaining peace, security, law and order in communities. The police operational and logistics staff work day to day with information and communication technologies, ranging from conventional databases and information systems to ubiquitous and specialised tools.  Understanding the use of technology and its management in policing has formed the backbone of this research conducted through a qualitative approach. This study adopted an interpretive paradigmic analytical lens using ethnography situated in the workplace as a methodology. The qualitative study took the form of field immersion for nine months using interviewing, and shadowing/observation to suit the complexity of the socio-technical context. Analysis was conducted using thematic analytical methods. Understanding how the police force interact with and shape the way that information and communication technologies enable them to fight crime is, then, the subject of this thesis. The findings highlighted the complexities and  intricacies involved in the use of technology, identifying unique differentiations in the way technology is engaged and integrated into policing including comparative understanding relative to other sectors and industries.  On the whole the central features of this work highlight understanding of the role information and communication technologies; usefulness, usage in practice and operational activity, strategic business goals, knowledge management, business intelligence and intelligence led architecture, governance and performance models in policing the county of Bedfordshire, England.

Adopting green information and communication technology: barriers for South African small and medium enterprises

Bok, Elizma Sharee 12 1900 (has links)
Abstracts in English, Afrikaans and Xhosa / Green information and communication technology (ICT) is viewed as a pioneering initiative that plays a key role in reducing the negative impact of ICT on the environment. The research problem of the study was the low green ICT adoption rate in South African small and medium enterprises (SMEs). The primary objective was to identify the most prominent barriers resulting in this low adoption rate. The first secondary objective was to determine the barrier with the strongest underlying correlation resulting in the low adoption rate of green ICT in South African SMEs. The second secondary objective was to recommend strategies on how to improve the adoption rate of green ICT. A self-administered questionnaire was used to collect data through electronic and paper-based surveys. A census study was conducted among owners and managers of high-technology-based SMEs located in Gauteng. An exploratory factor analysis was employed to identify the barriers resulting in the low adoption rate of green ICT. These barriers were found to be a lack of funding, awareness, legislation, skills, and knowledge based on complexity and uncertainty. A lack of funding was identified as the most prominent barrier to adopting low green ICT. Although five constructs were discussed in the literature, the overall results presented six components, with the construct of knowledge being made up of two parts – complexity and uncertainty. This study recommends that SMEs align green ICT initiatives with their strategic goals and that government consider more adequate support structures for SMEs. The study confirmed a low green ICT adoption rate in South African SMEs, and more research is required to explore the impact of each of the factors above on the environment. / Met groen inligting-en-kommunikasietegnologie (IKT) word baanbrekerswerk gedoen om die nadelige uitwerking wat IKT op die omgewing het, te verklein. Die trae tempo waarteen Suid-Afrikaanse klein en medium ondernemings (KMO’s) groen IKT aanneem was die navorsingsprobleem van hierdie studie. Die primêre oogmerk was om die grootste struikelblokke vir die aanneem van groen IKT aan te toon. Die eerste sekondêre oogmerk was om die struikelblok met die sterkste onderliggende korrelasie met die trae tempo waarteen Suid-Afrikaanse KMO’s groen IKT aanneem, te bepaal. Die tweede was om met strategieë te kom om die tempo te versnel waarteen groen ITK aangeneem word. Data is met ʼn selfvraelys deur elektroniese en papieropnames versamel. ʼn Sensusstudie is onder die eienaars en bestuurders van hoëtegnologie-KMO’s in Gauteng gedoen. Struikelblokke wat vir die trae aanneming van groen ITK verantwoordelik is, is met ʼn verkennende faktoranalise aangetoon. Daar is bevind dat gebrekkige befondsing en bewustheid, wetgewing, ʼn gebrek aan vaardighede en kennis weens die kompleksiteit en onsekerheid struikelblokke is. ʼn Gebrek aan befondsing was die grootste struikelblok vir die aanneem van groen IKT. Hoewel vyf konstrukte in die literatuur bespreek is, het die uitslag aangedui daar is ses. Die konstruk kennis is uit twee dele saamgestel: kompleksiteit en onsekerheid. Hierdie studie beveel aan dat KMO’s hulle groen IKT-inisiatiewe met hulle strategiese doelwitte in ooreenstemming bring, en dat die regering KMO’s beter ondersteun. Die studie bevestig die trae tempo waarteen Suid-Afrikaanse KMO’s groen ITK aanneem. Die invloed van elk van die bogenoemde faktore op die omgewing moet in verdere navorsing verken word. / Ulwazi lwezeMvelo kanye nobuchwepheshe bezokuxhumana (ICT) kuphawuleka njengemizamo yamaqhinga amasha adlala indima esemqoka ekunciphiseni umthelela omubi we-ICT kwezemvelo.

Using information to provide safe care for neonatal care unit patients : Medical staff interprets their use of information and communication technologies / Informationsanvändning för att tillhandahålla säker vård för patienter vid neonatalavdelning : Medicinsk personal tolkar sin användning av informations- och kommunikationsteknik

Stjerndorff Gröhn, Pia January 2020 (has links)
2017 became the beginning of the Childbirth Crisis of Sweden, as a result of underbudgeting and understaffing, creating an environment where patient safety and availability was questioned. Additionally, information and communication technology rapidly take a larger role in the field of healthcare, nourishing new solutions for old processes. This explorative research was conducted to answer how information and communication technologies, and communication techniques, are used and could be used to provide safe care for patients. This study was conducted with 10 participants working as medical staff at a Swedish neonatal care unit. The medical staff who participated consisted of registered nurses, certified pediatric nurses, pediatric nursing assistants, and one nursing assistant. The approach of this research was through system thinking in the tradition of soft systems thinking. The data collection was performed with a combination of semi-structured interviews and card sorting. The collected data were processed, organized, and interpreted with the three c’s of analysis and thematic analysis. The results of this study are complemented by rich pictures. The empirical findings of this study describe a neonatal care unit known at its hospital to be the one unit holding the largest number of different devices. The medical staff at the researched NCU are using information and communication technology in a combination together with specific communication techniques, to create an understanding of their patients’ conditions. The study connects a state of safe care to the training and knowledge of the information and communication technologies, and communication techniques used at the neonatal care unit. The combination of the information and communication technologies, and communication techniques used at the NCU are vital tools, conclusive to the medical staff when providing safe care for patients. This study provides an insight into one Swedish neonatal care unit, based on the interpretations of its medical staff.

From Vision to Transition : Exploring the Potential for Public Information Services to Facilitate Sustainable Urban Transport

Cano-Viktorsson, Carlos January 2014 (has links)
Background: Policy initiatives to promote sustainable travel through the use of Internet based public information systems have increased during the last decade. Stockholm, in being one of the first cities in Europe to implement an Internet based service for facilitating sustainable travel is believed to be a good candidate for an analysis of key issues for developing sustainable travel planning services to the public. Aim: This thesis investigates the past development of two Stockholm based public information systems and their services in order to draw lessons on how to better provide for a public information service geared towards facilitating  environmentally sustainable travel planning through information and communications technology. The overall goal of the thesis is to contribute to an understanding on how to better design and manage current and future attempts at facilitating sustainable travel planning services based on historical case studies. Approach: The thesis draws ideas from the concept of organizational responsiveness – an organization’s ability to listen, understand and respond to demands put to it by its internal and external stakeholders – in order to depict how well or not the two public information systems and their owners have adapted to established norms and values of their surroundings. Results: Overall, the findings from the historical case studies suggest that organizations attempting to provide sustainable travel planning to the public need to design and manage their systems in such a way that it responds to shifting demands on how to provide for information. Implementing and embedding new technologies involves complex processes of change both at the micro level – for users and practitioners of the service – and at the meso level for the involved public service organizations themselves. This condition requires a contextualist framework to analyze and understand organizational, contextual and cultural issues involved in the adoption of new technologies and procedures. Conclusions: The thesis concludes with a discussion on how the findings from the historical case studies may provide lessons for both current and future attempts at providing public information systems geared towards facilitating environmentally sustainable travel planning to the public. Historical examples and issues concerning collective intelligence and peer to peer based forms of designing, producing and supervising public information services identified throughout the study are looked upon and discussed in terms of their possible role in increasing the potential for public information services to facilitate sustainable urban transport. / <p>QC 20140319</p> / TRACS, Travel Planner for Sustainable Cities

Analysis Of Fastlane For Digitalization Through Low-Code ML Platforms

Raghavendran, Krishnaraj January 2022 (has links)
Even a professional photographer sometimes uses automatic default settings that come up with the camera to take a photo. One can debate the quality of outcome from manual vs automatic mode. Until and unless we have a professional level of competence in taking a photo, updating our skills/knowledge as per the latest market trends and having enough time to try out different settings manually, it is worthwhile to use Auto-mode. As camera manufacturers, after several iterations of testing, comes up with the list of ideal parameter values, which is embedded as a factory default setting when we choose auto-mode. For non-professional photographers or amateurs recommend using the auto-mode that comes with the camera for not missing the moment. Similarly, in the context of developing machine learning models, until and unless we have the required data-engineering and ML development competence, time to train and test different ML models and tune different hyper parameter settings, it is worth to try out to Automatic Machine learning feature provided out-of-shelf by all the Cloud-based and Cloud-agnostic ML platforms. This thesis deep dives into evaluating possibility of generating automatic machine learning models with no-code/low-code experience provided by GCP, AWS, Azure and Databricks. We have made a comparison between different ML platforms on generating automatic ML model and presenting the results. It also covers the lessons learnt by developing automatic ML models from a sample dataset across all four ML platforms. Later, we have outlined machine learning subject matter expert’s viewpoints about using Automatic Machine learning models. From this research, we found automatic machine learning can come handy for many off-the-shelf analytical use-cases, this can be highly beneficial especially for time-constrained projects, when resource competence or staffing is a bottleneck and even when competent data scientists want a second-opinion or compare AutoML results with the custom ML model built.

E-learning technologies for open distance learning knowledge acquisition in managerial accounting

Kashora, Trust 07 1900 (has links)
This research seeks to establish how e-learning may contribute towards knowledge construction for Management Accounting students at the University of South Africa. More specifically, the research is designed to investigate how educational technologies like e-learning may benefit and improve the teaching and learning of Management Accounting at Unisa. Educators need to understand how students learn so that they can establish suitable learning strategies. Studies have shown that generally, e-learning applications are little used, sometimes because of inappropriate content and technologies. Other prohibitive factors are costs, poor or inadequate technology infrastructure and a shortage of human resources. On the strength of a comprehensive literature survey, a framework to address and manage challenging aspects of teaching and e-learning were developed. Problem areas and critical success factors were considered. The said framework ought to assist with organising complex issues and reveal parts that need further work. The utility of the framework was evaluated through a staged process. First, it was tested and evaluated through the model of a lecture. Secondly, both qualitative and quantitative surveys among university lectures and students were conducted to further confirm the applicability of the framework. Though the outcome of the validations were satisfactory, more research needs to be carried out over a longer period of time in order to determine the scalability of the framework and to remove any inconsistencies. Aspects of the framework could be used to incorporate ICTs, e.g. the use of spreadsheets and the Learning Village into communities of practice. / Hierdie navorsing poog om vas te stel hoe e-leer kan bydra tot kenniskonstruksie vir Bestuursrekeningkunde-studente aan die Universiteit van Suid-Afrika. Die navorsing is meer spesifiek ontwerp om vas te stel hoe opvoedkundetegnologieë soos e-leer die onderrig en leer van Bestuursrekeningkunde by Unisa kan bevorder en verbeter. Opvoeders moet verstaan hoe studente leer sodat hulle geskikte leerstrategieë kan ontwikkel. Studies toon dat e-leertoepassings normaalweg min gebruik word, soms omdat die inhoud en tegnologieë nie toepaslik is nie. Ander faktore wat dit belemmer, sluit in onkoste, swak of onvoldoende tegnologie-infrastruktuur en ’n tekort aan mensehulpbronne. ’n Raamwerk om die uitdagings van onderrig en e-leer te bestuur, is op grond van ’n omvattende literatuurstudie ontwikkel. Probleemareas en kritiese suksesfaktore is in gedagte gehou. Die genoemde raamwerk behoort van nut te wees vir die organisering van ingewikkelde kwessies en toon watter dele verdere werk vereis. Die bruikbaarheid van die raamwerk is deur middel van ’n stapsgewyse proses geëvalueer. Eerstens is dit getoets en geëvalueer op grond van ’n lesingsmodel. Tweedens is kwalitatiewe en kwantitatiewe meningspeilings geloods; sowel universiteitsdosente as -studente is versoek om die toepaslikheid van die raamwerk te bevestig. Alhoewel die uitkoms van die validasies bevredigend was, moet verdere navorsing oor ’n langer tydperk gedoen word om die skaleerbaarheid van die raamwerk te bepaal en enige teenstrydighede uit die weg te ruim. Aspekte van die raamwerk kan gebruik word om IKT’s, bv die gebruik van sigblaaie en die Learning Village, by praktyksgemeenskappe te inkorporeer. / Ucwaningo lufuna ukuthola ukuthi ngabe ukufunda nge-e-learning noma ngendlela yeelektroniki kungafaka kanjani esivivaneni ekwakheni ulwazi kubafundi be- Management Accounting eYunivesithi yeNingizimu Afrika noma i-University of South Africa.

Mobile Apps and the ultimate addiction to the Smartphone : A comprehensive study on the consequences of society’s mobile needs

Beckhusen, Benedict January 2016 (has links)
The smartphone is omnipresent and is cherished and held close by people. It allows for constant connection within a digitally connected society, as well as for many other purposes such as leisure activity or informational purpose. Within the Information Systems studies deeper investigation is required as to what impact this “taken – for – granted” mobile access to information and mobile apps has for individuals and society and if a “technological addiction”can be developed when using the smartphone for everything during the day on such a constant basis. The aim of this study was to understand the role of the smartphone in society and to shed light on this unclear relationship between the constant use of a smartphone and its development towards an addictive quality. To reach a conclusion, in depth – interviews were conducted with participants about their relationship to the smartphone and their smartphone use based on questions derived from literature on mobile communication technologies and the types of digital addictions existing. The results are that the smartphone is a device that seamlessly integrates into our daily lives in that we unconsciously use it as a tool to make our daily tasks more manageable, and enjoyable. It also supports us in getting better organized, to be in constant touch with family and friends remotely, and to be more mobile which is a useful ability in today’s mobility driven society. Smartphones have been found to inhabit a relatively low potential to addiction. Traits of voluntary behaviour, habitual behaviour, and mandatory behaviour of smartphone use have been found. All of these behaviours are not considered a true addiction. In the end, it seems that the increase of smartphone use is mainly due to the way we communicate nowadays digitally,and the shift in how we relate to our social peers using digital means.

ICT adoption in a multicultural context: a case study of the African Union

Thuiya, Robert W. 04 1900 (has links)
Text in English with summary and key words in English, isiZulu and Afrikaans / Information and Communications Technology (ICT) adoption in a multicultural context needs to be well understood, since smooth ICT operations within several key sections of any multicultural organisation are impacted on by cultural factors. This study seeks to investigate the importance and effects of several variables – cultural tastes, cultural values, social structures, and the communication context and language – on ICT adoption in the African Union (AU). It also enhances understanding of issues faced by AU when adopting ICT in their daily operations. The study has reviewed theoretical literature, specifically Diffusion of Innovation Theory (DIT), Unified Theory of Acceptance and Use of Technology (UTAUT), The Competing Values Framework/Model, and Value-Based Adoption Model (VAM). The study used the value-based adoption model because in a multicultural environment such as AU, if an innovation is valuable and cost effective then they users are likely to adopt it. Reliability scores of the constructs were calculated by averaging the scores. The variables that could cause impact on ICT adoption included cultural values, social structure, culture taste, language and communication context. The tool was tested for reliability, and those questions that were found and unreliable questions were taken out from the final study. To enhance the test of validity of factors, Exploratory Factor Analysis (EFA) was preferred as the initial step in the validation process. The research was conducted at the AU offices within and outside of Ethiopia. A total of 288 participants completed a semi-structured questionnaire. Exploratory factor analysis was used. The findings indicate that language and cultural taste had a noteworthy effect at the stated significance level (α<0.05). Cultural values, communication, social structure and the communication context were found to be insignificant at the stated significance level (α<0.05). The study recommends that the AU embraces inclusivity of different and diverse languages into its ICT systems, to facilitate adoption and use by employees. In conclusion, the study points out that cultural tastes and languages are the vital elements in the adoption of ICT in the AU. / Ukwamukelwa kohlelo lezobuChwepheshe Bolwazi Kanye nokuXhumana (Information and communications technology (ICT) kwizidingo zesimo esiqukethe amasiko amaningi kufanele kuzwisiseke kahle, njengoba imisebenzi ehamba kahle yohlelo lwe-ICT kwimikhakha esemqoka yanoma iyiphi inhlangano enamasiko amaningi ithintwa yimithelela yosikompilo. Lolu cwaningo luqonde ukuphenya ukubaluleka Kanye nemithelela yezinto ezahlukene, kuxutshwa phakathi izinhlobo zamasiko, ubuhle bamasiko, izakhowo zomphakathi, Kanye nesimo sokuxhumana Kanye nolimi, phezu kokwamukelwa kwe-ICT kwinhlangano yoBunye be-Afrika (African Union (AU), ngenhloso yokuqinisa ulwazi lwezinto ezihlupha inhlangano ye-AU, uma yamukela uhlelo lwe-ICT kwimisebenzi yalo yansuku zonke. Ucwaningo luye lwabuyekeza ukuba khona ithiyori yombhalo wobuciko, ikakhulu ithiyori ebizwa nge-Diffusion of Innovation Theory (DIT), uhlelol lwe-Unified Theory of Acceptance and Use of Technology (UTAUT), uhlelo lwe-Competing Values Framework/Model Kanye ne-Value-based Adoption Model (VAM). Lolu hlelo lokugcina lusetshenzisiwe, ngoba kwisizinda samasiko amaningi esinjenge-AU, uma ngabe uhlelo lwamaqhinga amasha lutholakala lusemqoka futhi lungembi eqolo, ngakho-ke abasebenzisi balo bangalwamukela. Ucwaningo lwenziwa kumahovisi enhlangano ye-AU ezindaweni ezimbili ngaphakathi nangaphandle kwezwe lase-Ethiopia. Inani lonke labadlalindima aba-288 bagcwalise umbhalo wemibuzo ombaxambili.
