Designkrav för ett GIS-verktyg inom geografiundervisning på gymnasienivå

Wahlgren, Robin, Björnstedt, Carl January 2024 (has links)
Geographic Information Systems (GIS) has since it originated been making its wayinto different types of industries and higher education. However, one of the purposes regarding the teaching of geography in the upper secondary school in Swedenis to let students visualize and analyze spatial data by using GIS-tools. Previous research states that a broader implementation of GIS in the teaching of geography canbring opportunities such as new and more fun ways of teaching at the same time asstudents learn and develop essential knowledge for the future. Research howeverstates that there are constraints connected to the implementation of GIS in k-12 education and one of these originates from the idea that students and teachers potentially lack knowledge and have an overall negative attitude towards GIS. The implementation of GIS-tools which are adapted to fit the purpose of education at the desired level are therefore regarding to previous research a potential way of dealingwith this issue. This study aims to examine which requirements are to be included ina GIS-application from a teacher’s perspective to enhance usability and ease of use ofsuch tools. A prototype of a GIS-tool is going to be developed and evaluated together with this study to help determine the requirements to be expected from upper secondary school teachers regarding usability and ease of use.The research strategy chosen for this study is Design science. Semi-structured interviews have been conducted together with upper secondary school teachers at twodifferent occasions in this study. The first sets of interviews were conducted for collecting initial requirements for the prototype and the second sets of interviews wereconducted to evaluate the prototype. A theoretical framework has been used for thisstudy, both for supporting in creating questions for the interviews and for supporting in conducting two sets of deductive thematic analysis on the data collected. Thechosen theoretical framework for this study is The Technology Acceptance Model 3(TAM3), which fits the aim of this study as it has been able to assist in analysingtraits regarding perceived usefulness and perceived ease of use regarding a system.This study has developed a set of desired functional and non-functional requirementsfor GIS-applications intended to be used for the teaching of geography at the uppersecondary school level in Sweden. The result of this study also brings knowledgeabout other potential constraints regarding GIS-applications and its implementationin an educational setting; these regard the lack of student’s general computer skills,subject related knowledge, and resources. / Geografiska informationssystem (GIS) har under en längre tid varit en framväxandedel inom olika industrier och utbildning på högre nivå. Användning av tekniska redskap som GIS för att visualisera och analysera geografiska data ska enligt Skolverket iSverige ingå som ett syfte i geografiundervisning på gymnasial nivå. GIS som en delav grund- och gymnasieskolan har påvisats ha möjligheter att skapa roliga och moderna aktiviteter inom undervisning samtidigt som elever utvecklar goda kunskaperinför framtiden. Tidigare forskning har dock kommit fram till att GIS har svårigheteratt implementeras som en del av grund- och gymnasieskolans utbildning. Kunskapoch attityd gentemot GIS har påvisats bristande hos lärare och elever och verktyg anpassade för utbildning på lägre nivå är något tidigare forskning menar kan vara enmöjlig väg till förbättring. Syftet med studien är att undersöka vilka designkrav geografilärare ställer på en GIS-applikation för att underlätta användning av GIS som ettverktyg i deras undervisning. Detta genom att utveckla och utvärdera en prototypsom ämnas kunna fastställa krav relaterat till vad geografilärare anser att ett GISverktyg ska innefatta i form av användbara och användarvänliga egenskaper.Design science-metodologin har använts som vald forskningsstrategi för denna studie.Semistrukturerade intervjuer har genomförts med geografilärare på gymnasienivåfrån diverse skolor i Sverige, detta för både kravinsamling och utvärdering av studiens utvecklade prototyp. Ett teoretiskt ramverk har använts som stöd för skapandetav intervjufrågor och vid genomförandet av den deduktiva tematiska analysen idenna studie. Det teoretiska ramverket är The Technology Acceptance Model 3 (TAM3),vilket har passat denna studie då det har agerat som ett stöd för att analysera egenskaper relaterade till uppfattad användbarhet och uppfattad användarvänlighet förnågot system.Studien resulterade i att funktionella och icke-funktionella krav framställdes vilkageografilärare ställer på en GIS-applikation för att användas i undervisning inom geografiämnet. Resultatet lyfter även omkringliggande problematik gällande GISapplikationer med faktorer relaterade till bristande datorvana hos elever, ämneskunskap, samt resurser.

Mellan människa och maskin : En kvalitativ studie om artificiell intelligens påverkan på yrkesidentiteten och framtidens arbetsliv inom IT-branschen / Between Human And Machine : A Qualitative Study on Artificial Intelligence's Impact on Professional Identity and Future Working Life in the IT Industry

Bravo, Danielle, Makeeva, Yulia January 2024 (has links)
Syftet med studien är att fördjupa förståelsen om vilka upplevelser och attityder kring artificiell intelligens som kan inverka på IT-anställdas yrkesidentitet både idag och i framtiden. Vi tog kontakt med ett IT-konsultföretag och genomförde sju intervjuer med organisationens anställda. Datainsamlingen skedde genom en halvstrukturerad intervjuguide. I vår teoribakgrund har vi utgått ifrån en Teknikacceptansmodell (TAM), begreppet affordances, Goffmans identitetsteori samt en modell av interaktionen mellan arbete och identitet. Resultatet visar att samtliga respondenter använder sig av den generativa typen av AI där majoriteten är positivt inställda till tekniken och ser den som ett stöd och verktyg i det dagliga arbetet. De anställda ser artificiell intelligens som en bidragande och stärkande faktor i relation till deras yrkesidentitet idag, där AI som verktyg stöttar och frigör mer tid för kreativa, meningsfulla och relationsskapande arbetsuppgifter. Majoriteten av de anställda är positivt inställda och ser AI som en stärkande faktor för yrkesidentiteten i framtiden. Däremot fann vi en viss oro kring jobbförlust och professionell avkvalificering i framtiden, där AI:s potentiella kapacitet kan orsaka lidande för de IT-anställdas yrkesidentitet.

Fostering Financial Inclusion in Developing Countries: Predicting User Acceptance of Mobile Wallets in Cameroon

Fosso Wamba, S., Queiroz, M.M., Blome, C., Sivarajah, Uthayasankar 14 September 2020 (has links)
Yes / Financial inclusion is a vital development priority for countries worldwide. Mobile wallet (m-wallet) is considered as a disruptive payment method that will substitute the traditional physical wallet to achieve the so-called cashless society and enables financial inclusion. This study aims at developing and testing a research model that integrates a set of technology factors (perceived usefulness, perceived ease of use, fun to use, monetary value), external factors (peer influence and perceived status benefit), and cultural factors (humane orientation and societal collectivism) to assess the intention to adopt and use m-wallet, for financial inclusion, in a developing country. The proposed conceptual model is tested using data collected from 621 m-wallet users in Cameroon. The model explains 47.5% of the variance of the actual use of m-wallet and 32.90% of the variance of financial inclusion. Finally, implications for research and practice are discussed.

Singh, N.K., Sahu, G.P., Rana, Nripendra P., Patil, P.P., Gupta, B. 25 September 2020 (has links)
Yes / This paper studies the Critical Success Factors’ (CSFs) for the adoption of Digital Payment System in India. There are few studies about the literature on CSFs for the adoption of the digital payment system in the Indian context. This study is an attempt to cover this gap. In this study, we reviewed the theories for adoption model at the individual level used in Information System (IS) and discussed four technology model including “Technology Acceptance Model” (TAM). Ten factors have been identified with extensive literature review and review of selected models namely; Perceived Ease of Use, Perceived functional benefits, Awareness, Availability of Resources, Government as a policy maker, Performance Expectancy, Social Influence, Price Value, Experience & Habit, and Risk-taking ability. An expert from academic industry has been taken as a reviewer or consultant of the selected variables. The CSFs may ensure that they are the predictors and the important factors for adoption of digital payments system in India. The study mainly uses the deductive approach to consider the primary and secondary sources of data. The analyses of these models take into account through Interpretive Structural Modeling (ISM) methodology and develop a model for effective adoption of Digital Payment System in India. The paper also makes future recommendations for further research studies.

Understanding AI adoption in manufacturing and production firms using an integrated TAM-TOE model

Chatterjee, S., Rana, Nripendra P., Dwivedi, Y.K., Baabdullah, A.M. 07 May 2021 (has links)
Yes / This study aims to identify how environmental, technological, and social factors influence the adoption of Industry 4.0 in the context of digital manufacturing. The Industry 4.0 era has brought a breakthrough in advanced technologies in fields such as nanotechnology, quantum computing, biotechnology, artificial intelligence, robotics, the Internet of Things, fifth-generation wireless technology, fully autonomous vehicles, 3D printing and so on. In this study, we attempted to identify the socioenvironmental and technological factors that influence the adoption of artificial intelligence embedded technology by digital manufacturing and production organizations. In doing so, the extended technology-organization-environment (TOE) framework is used to explore the applicability of Industry 4.0. A conceptual model was proposed that used an integrated technology acceptance model (TAM)-TOE model and was tested using survey-based data collected from 340 employees of small, medium and large organizations. The results highlight that all the relationships, except organizational readiness, organizational compatibility and partner support on perceived ease of use, were found to be significant in the context of digital manufacturing and production organizations. The results further indicated that leadership support acts as a countable factor to moderate such an adoption.

A new methodology to optimize Turnaround Maintenance (TAM) scheduling for gas plants

Elwerfalli, A.A., Khan, M. Khurshid, Munive-Hernandez, J. Eduardo 01 1900 (has links)
Yes / Time, cost and risk are the main elements that effect the operating margin of the oil and gas companies due to Turnaround Maintenance (TAM). Turnaround Maintenance (TAM) is a methodology for the total shutdown of plant facilities during a pre-defined period to execute inspection actions, replacement and repairs according to Scope of Work (SoW). This paper presents a new methodology for improving TAM scheduling of oil and gas plants. The methodology includes four stages: removing Non-critical Equipment (NE) from reactive maintenance to proactive maintenance, risk-based inspection of Critical Static Equipment (CSE), risk-based failure of Critical Rotating Equipment (CRE), and application of failure distributions. The results from improving TAM scheduling is associated with decreasing duration and increasing interval between TAM leading to improved availability, reliability, operation and maintenance costs and safety risks. The paper presents findings from the TAM model application. The methodology is fairly generic in its approach and can also be adapted for implementation in other oil and gas industries that operate under similar harsh conditions.

Using TAM to Examine Faculty Perceptions of Online Learning at Technical Colleges in South Georgia

Sumter, La'Quata 05 1900 (has links)
The technology acceptance model (TAM) was used in this study to evaluate the faculty's perceptions of online learning. This study adopted a deductive approach that involved a move from theory formulation to data gathering. This study utilized a descriptive, correlational design to describe the study variables, which included the participants'' perceptions and attitudes. Perceived ease of use and perceived usefulness of technology have statistically significant correlations with technology competence levels of technical college faculty members, influencing their behavioral intentions to use online learning. Specific strategies that bolster perceived ease of use and perceived usefulness of technology in learning should be prioritized. These strategies include improving technological infrastructure, offering technology competency training, instituting facilitative technology use policies, and improving teacher-student motivation to use technology in learning.

Measuring Awareness and Ability of Students in Securing Personal Sensitive Data on Mobile Phones

Bukhari, Ahmed Abdulhakim T 12 1900 (has links)
This study investigates the awareness and ability of students at the University of North Texas (UNT) in securing their personal and sensitive information on mobile phones. In an era marked by increasing digitization, mobile phones play a pivotal role in our daily lives, making it essential to understand the practices and knowledge of individuals when it comes to safeguarding their personal information. To achieve this, the study adopts a multidimensional approach through the integration of three prominent theoretical frameworks, which are the technology acceptance model (TAM), the theory of planned behavior (TPB), and protection motivation theory (PMT). This integrated framework enables a comprehensive understanding of student perceptions, intentions, and motivations concerning mobile phone security. To gather data, a quantitative research method was employed, using a structured survey in the form of a questionnaire. Respondents were asked to rate their agreement with various statements using a 5-point Likert scale, ranging from 1 = strongly disagree to 5 = strongly agree. The survey included questions designed to assess student awareness, knowledge, attitudes, and behaviors related to securing personal information on their mobile phones. The findings of this study shed light on the existing gaps in the knowledge and practices of students related to mobile phone security. The outcomes can inform educational institutions and policymakers on the necessity of implementing awareness programs and security measures to protect personal information in the digital age. This research contributes to a deeper understanding of mobile phone security practices and paves the way for potential interventions to empower UNT students and users of mobile technology to protect their sensitive data effectively.

Développement touristique et développement local : la communauté lagunaire à Tam Giang-Cau Hai, province de Thùa Thiên Hué, Vietnam / Tourist development and local developpement : The lagoon community at Tam Giang-Cau Hai province of Thua Thien Hue's, Vietnam

Dam, Duy Long 17 November 2017 (has links)
Thừa Thiên Huế dispose d’une situation géographique stratégique, possédant des paysages somptueux, des villages artisanaux et d’une culture très riche avec deux patrimoines culturels mondiaux... Parmi les ressources naturelles potentielles de Hue, la lagune de Tam Giang - Cầu Hai (TG-CH), avec ses ressources précieuses, est une nouvelle destination touristique de cette province. À TG-CH, les activités touristiques sont apparues depuis 2010. Mais en réalité, le tourisme à la lagune de TG-CH ne montre pas vraiment qu’il est un outil efficace pour lutter contre la pauvreté pour la communauté lagunaire locale. Cette étude vise à un développement local durable en analysant plusieurs facteurs. Les analyses profondes sur les impacts touristiques, sur la participation communautaire dans le tourisme ont une relation directe avec la valeur perçue par la communauté locale sur le tourisme à TG-CH. Spécialement, une proposition initiale du « tourisme à la ville fantôme » dans la lagune de TG-CH montre une destination unique dans le monde entier que les responsables de Thừa Thiên Huế ne connaissent pas. Pour la première fois, la culture locale devient une clé importante pour comprendre, pour expliquer les pratiques des communautés locales. Cette recherche va être encore développée pour un développement local durable à TG-CH. / Thừa Thiên Huế inherites a strategic geographic position with many majestic landscapes, traditional villages and a diverse culture with two world cultural heritages. Among various potential natural resources of the place, Tam Giang – Cầu Hai Lagoon (TG-CH), with its precious resources, is an emerging tourist destination of the province. Althought tourism has established at TG-CH since 2010, it, in fact, has not shown as an effective tool for poverty alleviation. This research is aiming to a sustainable development of the area through analysing various factors. Analysises on the impacts of tourism and the involvement of local community in tourism have a very strong connection with the community perceived value in tourism. Specifically, a proposal for a model “tourism in the ghost town” at TG-CH would bring a unique aspect of a lost world which could not even be in the mind Thừa Thiên Huế authorities. For the first time, local culture becomes a significant key to understand and elaborate social changes. This research will continuously develop toward the sustainable development of TG-CH.

Le rgyalrong zbu, une langue tibéto-birmane de Chine du Sud-ouest. Une étude descriptive, typologique et comparative. / Zbu Rgyalrong, a Tibeto-Burman language of Southwestern China. A descriptive, typological and comparative study.

Gong, Xun 22 June 2018 (has links)
Cette thèse comporte deux volets complémentaires : d'une part, une description phonologique et morphologique du rgyalrong zbu, langue du groupe rgyalronguique du sino-tibétain ; d'autre part, une reconstruction de l'histoire de la flexion verbale de cette langue. Le volet descriptif vise à l'exhaustivité dans la description de la phonologie de cette langue, et pose les bases d'une grammaire de référence qui ambitionne notamment de situer sa morphologie flexionnelle dans une perspective de linguistique générale. Sur la base de cette description, élaborée au fil d'enquêtes de première main sur cette langue fortement en danger, un volet diachronique est proposé. Celui-ci contribue au projet général d'une reconstruction du groupe rgyalronguique, entreprise collective qui a des implications importantes pour la reconstruction du sino-tibétain dans son ensemble. Parmi les principaux résultats figurent une reconstruction du système de marquage de temps-aspect-modalité (TAM) de l'ancêtre commun le plus récent au japhug, au tshobdun et au zbu, désigné ici comme « proto-rgyalrong supérieur ». Cette reconstruction ouvre une perspective nouvelle pour bien distinguer entre éléments hérités et développements secondaires dans chacune des langues rgyalronguiques, ainsi qu'au sein du groupement supérieur (qianguique). Le volet diachronique comporte aussi un traitement comparatif de quelques verbes du zbu, à la lumière des données des langues qianguiques et lolo-birmanes, qui pourra servir de modèle pour un dictionnaire étymologique des verbes rgyalronguiques. / This thesis focuses on Zbu Rgyalrong, a Sino-Tibetan language of the Rgyalrongic branch, and consists of both a phonological and morphological description of the language and a reconstruction of the history of its verb inflection. This thesis aims at descriptive exhaustivity for its phonology and attempts to lay the foundation of a reference grammar, in order to characterize its inflectional morphology in the perspective of general linguistics. Based on the description of this highly endangered language, the thesis contains a diachronic discussion, which contributes to the project of reconstructing Proto-Rgyalrongic, a collective enterprise which has important implications for the reconstruction of Sino-Tibetan as a whole. Notably, a reconstruction is proposed of the time-aspect-modality (TAM) marking system of Proto-Upper-Rgyalrong, the most recent common ancestor of Japhug, Tshobdun and Zbu. This reconstruction provides new perspectives for distinguishing between inherited elements and secondary developments in each Rgyalronguic language, as well as within the kindred Qiangic languages. Also included in the diachronic part is a comparative treatment of some verbs in Zbu, examined with data from other Qiangic and Lolo-Burman languages, which can serve as a model for an etymological dictionary of Rgyalrongic verbs.
