Nurses' Acceptance of RFID Technology in a Mandatory-Use Environment

Norten, Adam 01 January 2011 (has links)
Radio frequency identification (RFID) technology allows for the scanning of RFID-tagged objects and individuals without line-of-sight requirements. Healthcare organizations use RFID to ensure the health and safety of patients and medical personnel and to uncover inefficiencies in operations. The successful implementation of a system incorporating RFID technologies requires acceptance and use of the technology. Nurses are a group of employees who must use RFID in hospitals throughout the United States. However, due to their being tracked by RFID technology, some of these nurses feel like "big brother" is watching them. This predictive study used a theoretical model that assessed the effect of five independent variables, namely, privacy concerns, attitudes, subjective norms, controllability, and self-efficacy, on a dependent variable, nurses' behavioral intention to use RFID. A total of 106 U.S. registered nurses answered a Web-based questionnaire containing previously validated and adapted questions that were answered through a five-point Likert scale. Two statistical methods, linear regression and multiple linear regression, were used to investigate the survey results. The results of the linear regression analysis showed that privacy concerns, attitudes, subjective norms, and self-efficacy were each a significant predictor of nurses' behavioral intention to use RFID. The results of the multiple linear regression analysis showed that all the constructs together accounted for 60% of the variance in nurses' intention to use RFID. Of the five predictors in the model, attitudes provided the largest unique contribution when the other predictors in the model were held constant. Subject norms also provided a unique contribution. The other predictors in the model (privacy concerns, controllability, and self-efficacy) were not statistically significant and did not provide a significant unique contribution to nurses' behavioral intention to use RFID. The outcomes of this study constitute a significant original contribution to the body of knowledge in the area of information systems by enhancing understanding of the factors affecting RFID acceptance among nurses. The results of this research also provide hospitals and medical centers that require their nurses to use RFID technology with information that they can use to address barriers to their nurses' acceptance and use of RFID technology.

Consumer adoption of audiobook streaming services

Nyström Müller, Jonathan, Engström, Casper January 2019 (has links)
The streaming of audiobooks is a new and fast-growing phenomenon amongst Swedish consumers. There exists a lack of knowledge on this topic as it is previously unexplored within academia. As the audiobook streaming services are growing it is important for providers and competitors to understand the key factors determining usage intention from an end-user’s perspective. This thesis therefore examines what factors influence end-user’s adoption of audiobook streaming-services, the examination extends both for consumers intention to begin using as well as continue using the service. Factors related to the end-user’s usage intention were explored and identified in a Swedish context. A theoretical model consisting of eight hypotheses was constructed to examine the relationships between five variables. The model is based on previous literature of technology adoption and in particular the technology acceptance model (TAM). Additional theory was gathered on previous research on similar technologies such consumers adoption of E-books and E-readers. To achieve the research purpose of the thesis, a quantitative method was used and data was gathered through an online questionnaire with 935 (769 valid) responses. Structural equation modeling (SEM) was used with RStudio to test the collected data on our theoretical model. The results showcased that our model was successful in explaining key factors influencing usage intention. The findings indicate that perceived usefulness and perceived ease of use influence usage intention positively, while end-user’s attachment to paper books and reading impact usage intention negatively. Further results and the implications of these results are discussed.

Indiana Farmers' Level of Adoption and Perceptions of Mobile Applications as Agricultural Management Tools

Jaclyn Renae Leeuw (6635954) 14 May 2019 (has links)
<p>Farmers in the digital age require accurate, relevant farm-level data to make sound management decisions for their operations. Mobile applications, or apps, are emerging as a valuable management and decision-making tool for farm operators, but are still in their infancy as a technological innovation. Farmer adoption and use of mobile apps has received relatively little attention in the scholarly literature compared to more established farm management tools and communication media. The researcher examined Indiana farmers’ use and perceptions of mobile apps as tools for management and decision-making. A theoretical perspective was developed from the Diffusion of Innovation Theory and the Technology Acceptance Model to guide the investigation. Data on attitudes, behaviors, and demographic characteristics were collected through interviews with 55 Indiana farmers in late 2018 and early 2019. Quantitative interview items were analyzed through descriptive statistics while open-ended items were coded for emergent themes.</p> <p>Study participants reported a median age of 41 years and an average of 26 years farming. Nearly all study participants (98.2%) considered mobile applications useful to farm operations. A smaller but significant majority (76.4%) of participants rated mobile apps as easy to use. In terms of content, the most common use of apps among study participants was for general purpose utilities such as banking and messaging, followed by weather and agriculture-related apps such as Granular and FieldNet. Ease of use and content of application were among attributes considered most important by study participants when considering adoption of new apps. About three-fourths (76.4%) of the study participants indicated intentions to adopt additional mobile applications in the future. </p> <p>A series of items addressed study participants’ awareness of open source technology. About three-fourths (72%) indicated not previously having heard of the terminology. When asked to share their thoughts on the term open source, a large majority (84%) of participants provided vague or seemingly unrelated responses ranging from cloud-related, to the capability of apps to exchange information, to software being open to all users. </p> <p>As part of the analysis, the researcher categorized study participants into one of three adopter categories – early adopters, early majority, or late majority – based on the length of time participants reported using mobile apps, attitudes toward the technology, and intention to adopt apps in the future. Cross-tabulation analysis revealed that early adopters of mobile app technology did not differ significantly at the .05 level from later adopters in terms of age, years farming, or size of operation.</p> <p>Finally, an empirical test was conducted to assess utility of the Technology Acceptance Model for conceptualizing behavioral intent to adopt mobile agricultural applications. As expected from theory, correlational analysis revealed positive and moderately strong relationships (p < .05) between perceived usefulness and attitude toward mobile applications, and between perceived ease of use and attitude toward mobile applications. The relationship between attitude and behavioral intention to adopt additional mobile applications was statistically non-significant at the .05 level, contrary to theory. The importance of exploring alternative theoretical perspectives in future research is discussed.</p> <p>Results from this research contribute to the growing literature on how farmers assess and use mobile applications as farm management and decision-making tools. Findings have implications for application developers, as well as those involved in education and marketing of mobile agricultural applications. </p>

Digitala plånböcker : En studie om acceptansen av de digitala plånbokstjänsterna Apple Pay och Samsung Pay

Grapenson, Anna, Vestman, Josefin January 2019 (has links)
Vi går mot ett allt mer kontantlöst samhälle, där mobilbetalningar är det betalsätt som används mest efter kortbetalningar. Idag finns det ett stort urval av olika mobila betalningstjänster på marknaden. I denna studie kommer acceptans av digitala plånböcker att undersökas. Digitala plånböcker är betaltjänstapplikationer som bl.a. kan användas för att online och i fysisk butik. Mer specifikt kommer vi att undersöka de digitala plånböckerna Apple Pay och Samsung Pay, vilka är relativt nylanserade på den svenska marknaden. I och med det nya betaltjänstdirektivet (PSD2) som initierades av EU, förväntas fler företag tillhandahålla betalningstjänster som bygger på bankernas API och använda kundens kontoinformation. Denna potentiella förändring av den finansiella marknaden, där företag istället för banker tillhandahåller kunders kontoinformation och sköter deras finansiella tjänster, väcker frågor angående kunders uppfattade förtroende och risk. Syftet med studien var att undersöka vilka faktorer som påverkade användares acceptans och avsikten att använda dessa digitala plånböcker. Dessa faktorer baserades på E-commerce acceptance model, vilken baserades på den etablerade modellen Technology Acceptance Model (TAM) och litteratur om faktorerna risk och förtroende. Data som låg till grund för empirin hämtades från elektroniska enkäter. Resultatet påvisade att faktorerna uppfattad nytta och förtroende hade starkast påverkan på respondenternas avsikt att använda de digitala plånböckerna. Resultatet och urvalet diskuterades även utifrån teorin Diffusion of Innovations för att kontextualisera studien. / We are moving towards an increasingly cash-free society, where mobile payments are the most frequently used payment method after card payment. Today there is a wide selection of different mobile payment services on the market. This study will focus on acceptance of digital wallets, which are payment service applications that can be used online as well as in physical stores. More specifically, we will examine the digital wallets Apple Pay and Samsung Pay, which are newly launched on the Swedish market. With the new Payment Service Directive (PSD2) initiated by the EU, more companies are expected to provide payment services based on the bank's APIs to use the customer's account information. This potential change in the financial market, where companies instead of banks manage customer account information and financial services, raises questions about customers' perceived trust and risk. The purpose of this study was to investigate which factors influenced users' acceptance and intent to use digital wallets. These factors are based on the E-commerce acceptance model, which was based on the established model Technology Acceptance Model (TAM) and literature on the factors risk and trust. The data which the results were based upon were obtained from electronic surveys. The results indicated that the factors perceived usefulness and trust had the strongest impact on respondents' intention to use the digital wallets. The result and sample were also discussed based on the theory Diffusion of Innovations to contextualize the study.

O envolvimento do usuário como influência na adoção de sistemas de informação

Leso, Bernardo Henrique January 2018 (has links)
A presente pesquisa visa investigar o envolvimento do usuário final no desenvolvimento de um Sistema de Informação (SI) e sua influência na adoção do SI. Para tanto, realizou-se uma revisão sistemática, em que foram analisados 133 artigos e cujo resultado é a proposição de uma modificação do Modelo de Aceitação de Tecnologia (TAM) incluindo variáveis relativas ao envolvimento do usuário: situacional e intrínseco. Em seguida, foi realizado o teste do modelo proposto a partir de uma survey com 114 respondentes, cujos dados foram analisados através de Análise Fatorial Exploratória (EFA), Análise Fatorial Confirmatória (CFA) e Modelagem por Equações Estruturais (SEM). O teste permitiu inferir que as hipóteses suscitadas estavam corretas e que o envolvimento do usuário é significativo dentro do contexto de adoção de um SI. Por fim, realizou-se um projeto de experimentos fatorial (DOE) fracionado para verificar de que forma envolvimento situacional e intrínseco estão relacionados Evidenciou-se que a composição do efeito de fatores principais e de interações duplas das atividades do envolvimento situacional explica até 57% da variação do envolvimento intrínseco. As principais contribuições teóricas da dissertação versam sobre a consistência aportada pelos métodos utilizados. O subsídio teórico aportado pela revisão sistemática permitiu elaborar relações teóricas com segurança. A utilização conjunta de EFA e CFA é indicada para conferir robustez à pesquisa. Da mesma forma, a modelagem por equações estruturais apresentou utilidade no contexto da pesquisa, embora se indique cuidado ao realizar as modificações no modelo para que se adeque aos parâmetros de qualidade da análise. Por fim, a realização de um projeto de experimento fatorial fracionado é algo incomum na literatura de adoção de SI, mas foi útil para verificação da qualidade da interação entre os tipos de envolvimento, bem como a verificação de quais fatores devem ser evitados. / The present research aims to understand the end user involvement in the Information System (IS) development influence in IS adoption by proposing and testing a specific theoretical model. A systematic review was carried out in which 133 articles were analyzed and its result is a Technology Acceptance Model (TAM) modification proposition. This model includes variables related to the user's involvement: situational involvement and intrinsic involvement. Afterwards, the test of the proposed model was carried out from a survey with 114 respondents, whose data were analyzed through Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM). The test allowed inferring that the hypotheses raised were correct and that user involvement is significant within IS adoption context. Finally, a fractional factorial design of experiments (DOE) with seven factors was done to verify how two types of involvement are related. It was evidenced that the composition of the effect of situational involvement major factors and double interactions explains up to 57% of intrinsic involvement variation The main theoretical contributions of the dissertation are about the consistency provided by the methods used. The theoretical subsidy provided by the systematic review allowed development of theoretical relations with safety. The combined EFA and CFA use is strongly indicated to give robustness to the research. Likewise, SEM presented significant utility in research context, although it is indicated caution when making model modifications to fit analysis quality parameters. Finally, fractional factorial DOE with seven factors is uncommon in the literature, but it was extra useful to verify interaction quality between types of involvement.

Factors Associated with Provider Utilization of the Heath Information Exchange in the State of Hawaii

Wilson, Kris K. 01 January 2017 (has links)
In a context where technology is increasingly being incorporated into health care practice, many U.S. health care providers and organizations are finding it challenging to connect disparate electronic documentation systems to retrieve patient information when coordinating care across providers and heath care entities. Local and regional health information exchange (HIE) systems were created to facilitate collecting information into one integrated patient record to address information transfer between heath care providers. Yet, adoption and use of HIEs have been low. The purpose of this study was to review the predictive factors accounting for physicians' use of a HIE in the U.S. state of Hawaii. Key factors from the technology acceptance model were evaluated to determine the behavioral intention resulting in actual use of the Hawaii health information exchange (HHIE). Physician characteristics (medical specialty, age, and gender) and location characteristics were also assessed. The total population of the study contained 1034 Hawaii physicians who have signed up to use the HHIE. Linear and logistic regression models were structured to evaluate the predictive nature of (a) use to determine if a physician has ever logged into the HIE and (b) usage to evaluate the extent to which a physician is logging into the HIE. Findings from the study reveal a predictive relationship between the characteristic of medical specialty and HHIE use when comparing primary care and emergency department physicians to physician specialists. Using study results, health care leaders can improve physician outreach and review barriers when using the HIE systems to coordinate care. Policy implications include the possible formulation of future requirements surrounding HIE physician participation.

Enterprise Architecture for Information System Analysis : Modeling and assessing data accuracy, availability, performance and application usage

Per, Närman January 2012 (has links)
Decisions concerning IT systems are often made without adequate decision-support. This has led to unnecessary IT costs and failures to realize business benefits. The present thesis presents a framework for analysis of four information systems properties relevant to IT decision-making. The work is founded on enterprise architecture, a model-based IT and business management discipline. Based on the existing ArchiMate framework, a new enterprise architecture framework has been developed and implemented in a software tool. The framework supports modeling and analysis of data accuracy, service performance, service availability and application usage. To analyze data accuracy, data flows are modeled, the service availability analysis uses fault tree analysis, the performance analysis employs queuing networks and the application usage analysis combines the Technology Acceptance Model and Task-Technology Fit model. The accuracy of the framework's estimates was empirically tested. Data accuracy and service performance were evaluated in studies at the same power utility. Service availability was tested in multiple studies at banks and power utilities. Data was collected through interviews with system development or maintenance staff. The application usage model was tested in the maintenance management domain. Here, data was collected by means of a survey answered by 55 respondents from three power utilities, one manufacturing company and one nuclear power plant. The service availability studies provided estimates that were accurate within a few hours of logged yearly downtime. The data accuracy estimate was correct within a percentage point when compared to a sample of data objects. Deviations for four out of five service performance estimates were within 15 % from measured values. The application usage analysis explained a high degree of variation in application usage when applied to the maintenance management domain. During the studies of data accuracy, service performance and service availability, records were kept concerning the required modeling and analysis effort. The estimates were obtained with a total effort of about 20 man-hours per estimate. In summary the framework should be useful for IT decision-makers requiring fairly accurate, but not too expensive, estimates of the four properties. / <p>QC 20120912</p>

Changing Consumption Behavior of Net Generation and the Adoption of Streaming Music Services : Extending the Technology Acceptance Model to Account for Streaming Music Services

Delikan, Mehmet Deniz January 2010 (has links)
The rise of the streaming music services and the decreasing importance of physical distribution is an inevitable change that the industry has been facing, which is resulting from the so-called internet revolution over the past few years. Through years, the music business has already shifted to online platform with the birth of file sharing. Today, a generation who had grown up digital came to age. Members of this generation have different consumption habits than before, and have different motives toward consumption. The consumer behavior of this group was examined at different stages of the digital revolution during last decade. However, although there is a wide number of researches have examined online consumer behavior and the adoption file-sharing technologies, no study investigated the use of streaming music services. Therefore, in order to understand the changing consumption behavior of the net generation music consumers, and to under-stand the use of streaming music services, this study extends the Technology Acceptance Model (TAM) to account the streaming music services. A questionnaire based empirical study was administrated among the users of Sweden based streaming music service Spotify. Results confirm that there is a significant relationship between users‟ perceived usefulness of service use, and their attitude toward using and their behavioral intention to use. In addition, it is also confirmed by the results that advertisement/charge, flow, and social influence are effective in explaining the motives of users‟, and the use of streaming music services. Furthermore, according to the findings of the study streaming music services have a positive effect on decreasing the music piracy.

Factors influencing Chinese Consumer Online Group-Buying Purchase Intention: An Empirical Study

LIU, DOUQING January 2013 (has links)
Background: Because of the high-speed development of e-commerce, online group          buying has become a new popular pattern of consumption for Chinese consumers. Previous research has studied online group-buying (OGB) purchase intention in some specific areas such as Taiwan, but in mainland China. Purpose:    The purpose of this study is to contribute to the Technology Acceptance Model, incorporating other potential driving factors to address how they influence Chinese consumers' online group-buying purchase intentions. Method:     The study uses two steps to achieve its purpose. The first step is that I use the focus group interview technique to collect primary data. The results combining the Technology Acceptance model help me propose hypotheses. The second step is that the questionnaire method is applied for empirical data collection. The constructs are validated with exploratory factor analysis and reliability analysis, and then the model is tested with Linear multiple regression.  Findings: The results have shown that the adapted research model has been successfully tested in this study. The seven factors (perceived usefulness, perceived ease of use, price, e-trust, Word of Mouth, website quality and perceived risk) have significant effects on Chinese consumers' online group-buying purchase intentions. This study suggests that managers of group-buying websites need to design easy-to-use platform for users. Moreover, group-buying website companies need to propose some rules or regulations to protect consumers' rights. When conflicts occur, e-vendors can follow these rules to provide solutions that are reasonable and satisfying for consumers.

Pedagogers adaption av surfplattor : En studie av implementeringen av iPad i en F-5 skola

Johansson, Sara January 2012 (has links)
The tablet is a new IT-tool which have started to get introduced into school, but research is still missing and especially in the pre-school environment. The purpose with this study is to investigate teachers uptake, how they use the tablet in everyday pedagogy work as well as the organizational conditions that that facilitate and hinders. Through my observations and interviews in a Swedish K-5 school I have found that the teachers find tablets more appealing to use in comparison to computers. These findings are partly supported by Davis et al.’s (1989) TAM-theory who considers there to be three types of aspects that affect the way individuals adapt to technology. Firstly the teachers’ motivation increased when they saw the usefulness in the tablet in both educational and administrative possibilities. Secondly, the tablet is perceived as an ease of use-artifact which in it self gives the teachers incentive for usage. Thirdly, the infrastructure problem that exists around computers creates an escape to the more appealing tablets.
