Assessing Early-Stage Research Results: An Application of Characteristics of Innovation Frameworks

Alhassan, Enas January 2015 (has links)
The aim of this study is to identify characteristics that can be used to assess early-stage research results by research users and research producers of the advanced biofuel sector. Mainly, it qualitatively explores the perceptions of both research users and research producers regarding their experiences with research results. The study builds on the models of Diffusion of Innovation (DoI), Technology Acceptance Model (TAM) and Perceived Characteristics of Innovation (PCI). The findings of this study suggest that the investigated dimensions of DoI, PCI and TAM are applicable to the context of assessing research results with the extra dimension of risk reduction. In particular, some of the criteria used to assess the usefulness of research results are through its originality, scalability and relevance. The findings also suggest that documentation and publication are important to research users: Research users assess ease of use based on the presentation of the research results in their documentation; and they assess the quality of research results based on publications and the reputation of researchers. The findings of this study can be used to tailor research results to research users’ needs, which in turn can be expected to improve the uptake and further development of research results. This will not only permit the push of scientific research results to research users only put also permit research users to inform research needs.

Bitcoin som diversifiering : En kvantitativ studie som undersöker korrelationen mellan bitcoin och finansiella tillgångar

Gleisner, Mattias, Edström, Karoline January 2017 (has links)
Pengar har under en lång tid spelat en central roll i människans samhälle och dagens samhälle präglas av allt mer handel. Utifrån detta har nya betalningsmetoder utvecklats. En förändring i konsumentbeteendet har bidragit till att allt fler individer väljer elektroniska betalningstjänster. En relativt ny innovation är kryptovalutan bitcoin som erbjuder betalning mellan köpare och säljare utan inblandning av en tredje part. Ett flertal studier har gjorts med syftet att fastställa om bitcoin är en valuta eller en tillgång, något som visat sig vara svårt. Något som varit tydligare är att bitcoins värdeförändringar inte tycks vara korrelerad med andra investeringsalternativ. I en studie av Brière et al. (2015) drogs slutsatsen att bitcoin är en intressant tillgång för en investerare tack vare bitcoins låga korrelationskoefficient med andra tillgångar. Denna studie grundar sig i de teoretiska utgångspunkterna om Famas (1970) hypotes om den effektiva marknaden, Markowitz (1952) moderna portföljteori och Rogers (2003) teori om spridning av innovationer. Med detta som utgångspunkt är syftet med denna studie att undersöka hur korrelationskoefficienten mellan bitcoin och traditionella investeringstillgångar som aktier, valutor och råvaror ser ut idag samt hur dessa har förändrats över tid. Med hjälp av Famas (1970) teori om effektiva marknader och Rogers (2003) teori om spridning av innovationer kommer en diskussion om huruvida bitcoins egenskaper som investering i den moderna portföljen har förändrats i takt med att bitcoin blivit mer använd, både som betalningsmedel och investeringsalternativ. För att besvara dessa frågor undersöks korrelationskoefficienterna mellan bitcoin och elva andra tillgångar i kombination med en analys av en deskriptiv statistik. Med en undersökningsperiod som sträcker sig från 18 augusti 2011 till 17 mars 2017. Denna period har även delats upp i mindre tidsperioder för att utifrån detta analysera om det skett några förändringar i korrelationen mellan bitcoin och de traditionella tillgångarna i studien. Resultatet visade att bitcoin inte är korrelerad med andra traditionella tillgångar, oavsett vilken tidsperiod som undersöks. Det visade sig att bitcoin i förhållande till andra tillgångar är en riskfylld investering på grund av bland annat en hög volatilitet. Dock kompenseras detta av bitcoins höga årlig avkastning. Av resultatet framgår det även att volatiliteten för bitcoin har minskat med tiden och att kryptovalutan inte är lika riskfylld idag jämfört med tidigare.

Impact of a Healthcare Workplace Violence Prevention Module on Staff Knowledge

Arroyo, Michelle Leigh 01 January 2019 (has links)
The healthcare sector experiences violence 4 times as much as any other civilian domain, including law enforcement and corrections facilities. The clinical practice problem addressed in this project was the lack of adequate healthcare workplace violence (HWV) prevention in a not-for-profit community hospital. The purpose of this project increase awareness of HWV prevention through the use of an education module. Rogers’ diffusion of innovation model served as the foundation for analysis of scores from pre- and posteducation tests. The practice-focused question asked if a module on HWV prevention based on current clinical practice guidelines and peer-reviewed literature would improve staff members’ knowledge on workplace violence. A staff education project was designed to address the practice problem. The research design was an anonymous pre- and posttest for score comparison to analyze data by noting changes in proportion of correct answers. Nursing professionals (N = 14) participated in the education module and pre- and posttests. The percent of correct answers to 18 knowledge-related questions increased from 82% on the pretest to 91% on the posttest. The facility elected to expand the project to a more comprehensive program and requested additional modules to broaden understanding of and sustain HWV prevention strategies. These efforts will enact positive social change for healthcare staff by promoting a culture that embraces a safe work environment, increases staff knowledge on HWV prevention, decreases HWV and is supported by organizational systems.

Accessibility of Innovative Services in Radiation Oncology

Sansourekidou, Patricia 01 January 2019 (has links)
The field of radiation oncology (RO) involves the use of highly advanced techniques to treat cancer and safely spare healthy organs. The discipline has experienced rapid growth in the past 25 years, with technological advancement as the driving force. Available data and an instrument to effectively measure the accessibility of innovation in the field were lacking. The purpose of this study was to investigate the accessibility of innovative services in RO in the United States and assess possible diffusion patterns. Two hundred and forty medical physicists practicing in RO in the United States completed a custom Internet-based survey. The diffusion of innovation theory was used as the theoretical framework for the study. A quantitative cross-sectional analysis was performed to assess how innovation scores may vary depending on individual and organizational factors. ANOVA, Spearman correlation, and multiple linear regression were used to analyze the data. University affiliation, urbanicity, appreciation, and motivation were found to be statistically significant factors affecting accessibility to innovative services. Statistically significant barriers preventing innovation were lack of evidence, increased complexity, staffing constraints, lack of interest from others, lack of interoperability, and lack of reimbursement. Medical physicists are in a leadership position to influence the adoption of innovative services in RO. Encouraging the utilization of innovative and Food and Drug Administration-approved techniques may improve cancer outcomes and consequently have a positive social change effect on public health.

Cryptocurrency as a Payment Method in the Retail Industry : An application of Diffusion of Innovation Theory (DOI) on the characteristics of Bitcoin: the case of Bitrefill

Mukabi, Collins, Vu, Nguyen Long January 2019 (has links)
Background: The convergence of payment behaviours can contribute to the diffusion of new payment technologies and thus economic performance. There is evidence that the electrification of the retail payment system promotes the performance of the banking sector and economic growth. The retail payment market is a prime example of a two-sided market where new payment instruments need to reach a critical mass of users to become viable and grow further (Martikainen, Schmiedel & Takalo, 2015). Purpose: The purpose of this paper is to analyse Bitcoin, as a payment method, and review the models already used to shed more light on its further potential adoption by retailers. We apply the DOI theory and review the TAM model to determine the underlying characteristics of Bitcoin that will enable further adoption or rejection among retailers. Method: We conduct a case study on Bitrefill AB which offers a rich method for investigating and researching. With the process of interpretation in context, we make inference from the case of Bitrefill in connecting with events and experiences of other retailers (Expedia, Alibaba, Overstock and CheapAir). Conclusion: According to the results, the adoption of Bitcoin relies heavily on positive relative advantages to other payment methods, compatibility and simplicity of its use while negative characteristics that pull it back from being adopted include the complexities in understanding the technology behind it, damaging outcomes varying from the expected.

Public School Educators' Use of Computer-Mediated Communication

Urias-Barker, Zelina 12 1900 (has links)
This study examined the uses of computer-mediated communication (CMC) by educators in selected public schools. It used Rogers' Diffusion of Innovation Theory as the underpinnings of the study. CMC refers to any exchange of information that involves the use of computers for communication between individuals or individuals and a machine. This study was an exploration of difficulties users confront, what services they access, and the tasks they accomplish when using CMC. It investigated the factors that affect the use of CMC. The sample population was drawn from registered users on TENET, the Texas Education Network as of December 1997. The educators were described with frequency and percentages analyzing the demographic data. For the research, eight indices were selected to test how strongly these user and environmental attributes were associated with the use of CMC. These variables were (1) education, (2) position, (3) place of employment, (4) geographic location, (5) district size, (6) organization vitality, (7) adopter resources, and (8) instrumentality Two dependent variables were used to test for usage: (1) depth or frequency of CMC usage and amount of time spent online and (2) breadth or variety of Internet utilities used. Additionally, the users' perception of network benefits was measured. Network benefits were correlated with social interaction and perception of CMC to investigate what tasks educators were accomplishing with CMC. Correlations, SEQ CHAPTER h r 1 crosstabulations, and ANOVAs were used to analysis the data for testing the four hypotheses. The major findings of the study, based on the hypotheses tested, were that the socioeconomic variables of education and position influenced the use of CMC. A significant finding is that teachers used e-mail and for Internet resources less frequently than those in other positions. An interesting finding was that frequency of use was more significant for usage than amount of time spent online. This implied that an accessible computer and network connection was more important than the amount of time available to use it. There was little evidence that place of employment, geographic location, or school district size influenced differences in use or nonuse of CMC features. Significant findings for Organization Vitality suggest that a school could contribute to usage by educators when computers and network connections that were close, convenient, and accessible. The Individual Resources of importance for usage were years of experience and confidence with computers and Internet usage. The heavy uses of CMC for communication attested to the importance of CMC in reducing practitioner isolation for many educators. Communication, professional development, work productivity, and professional information seeking showed significant relationships with network benefits and perceived CMC attributes. CMC is a pervasive communication technology that continues to expand in all areas of society. For educators and education it is a venue promising great rewards.

The Swedish mobile Payment market: An analysis from a consumer’s perspective

Eriksson Talls, Martin, Trinh, Van January 2012 (has links)
The objective of this research is to understand how consumers perceive mobile payment services and the consumers’ maturity level to adopt mobile payments in the Swedish market. To reach our objective interviews were conducted asking about consumers experience with current payment methods and how consumers perceive mobile payment services. Questions from the interviews are derived from theories about technology adoption mainly from Diffusion of Innovations and Technology Acceptance Model. In addition questions about how consumers perceive mobile payment services are based on existing and concept based features. The results show that consumers are open to, and can even consider paying to use the mobile phone as a payment instrument. At the moment mobile payment services are either based on Near Field Communication (NFC) or Quick Response (QR) code technologies at Point of Sale(POS) purchases. Consumer perceive each payment solution differently; NFC based payments were perceived as more convenient while QR code were perceived as more secure. In addition mobile payment services have the potential to incorporate additional features that can increase its attractiveness, such as storing loyalty cards digitally and the ability to transfer moneybetween accounts. The maturity level among the consumers are in an early stage because their knowledge about mobile payment services is very low at the moment, due to that the interviewees did not consider themselves as early adopters when new technologie s are introduced.

The adoption of Industry 4.0- technologies in manufacturing : a multiple case study

NILSEN, SAMUEL, NYBERG, ERIC January 2016 (has links)
Innovations such as combustion engines, electricity and assembly lines have all had a significant role in manufacturing, where the past three industrial revolutions have changed the way manufacturing is performed. The technical progress within the manufacturing industry continues at a high rate and today's progress can be seen as a part of the fourth industrial revolution. The progress can be exemplified by ”Industrie 4.0”; the German government's vision of future manufacturing. Previous studies have been conducted with the aim of investigating the benefits, progress and relevance of Industry 4.0-technologies. Little emphasis in these studies has been put on differences in implementation and relevance of Industry 4.0-technologies across and within industries. This thesis aims to investigate the adoption of Industry 4.0-technologies among and within selected industries and what types of patterns that exists among them. Using a qualitative multiple case study consisting of firms from Aerospace, Heavy equipment, Automation, Electronics and Motor Vehicle Industry, we gain insight into how leading firms are implementing the technologies. In order to identify the factors determining how Industry 4.0-technologies are implemented and what common themes can be found, we introduce the concept production logic, which is built upon the connection between competitive priorities; quality, flexibility, delivery time, cost efficiency and ergonomics. This thesis has two contributions. In our first contribution, we have categorized technologies within Industry 4.0 into two bundles; the Human-Machine-Interface (HMI) and the connectivity bundle. The HMI bundle includes devices for assisting operators in manufacturing activities, such as touchscreens, augmented reality and collaborative robots. The connectivity-bundle includes systems for connecting devices, collecting and analyzing data from the digitalized factory. The result of this master thesis indicates that depending on a firm’s or industry’s logic of production, the adoption of elements from the technology bundles differ. Firms where flexibility is dominant tend to implement elements from the HMI-bundle to a larger degree. In the other end, firms with few product variations where quality and efficiency dominates the production logic tends to implement elements from the connectivity bundle in order to tightly monitor and improve quality in their assembly. Regardless of production logic, firms are implementing elements from both bundles, but with different composition and applications. The second contribution is within the literature of technological transitions. In this contribution, we have studied the rise and development of the HMI-bundle in the light of Geels (2002) Multi-Level Perspective (MLP). It can be concluded that an increased pressure on the landscape-level in the form of changes in the consumer-market and the attitudes within the labor force has created a gradual spread of the HMI-bundle within industries. The bundles have also been studied through Rogers (1995) five attributes of innovation, where the lack of testability and observability prevents increased application of M2M-interfaces. Concerning Big Data and analytics, the high complexity prevents the technology from being further applied. As the HMI-bundle involves a number of technologies with large differences in properties, it is hard draw any conclusion using the attributes of innovation about what limits their application.

A survey of gender differences in technophobia and in the adoption of high-technology consumer products

Anderson, Olivia 06 May 2011 (has links)
Despite the advent of technology into consumers’ daily lives, many consumers are plagued by feelings of fear towards complex technology-related products. Feelings of anxiety and fear often lead to the avoidance of technology; in other words, so-called ‘technophobia’. This study aims to establish whether gender differences in technophobia and the adoption of high-technology consumer products continue to exist in this digital age, or whether they have indeed changed over time. Further, this study also aims to uncover the main social reasons that gender differences in technophobia can occur. The results of this study provide new insight into gender differences towards technology purchases. The findings should assist marketers by providing a clearer understanding of how men and women adopt new technology products in the 21st century. By understanding gender differences in attitudes towards technology, marketers are better able to target and communicate technology benefits that consumers can relate to and appreciate. Following a review of the available literature, the theory of the diffusion of innovation was presented as a foundation to studies of gender differences in technophobia. The Technology Readiness Index (TRI) was introduced as a sound means of measuring technophobia, based on an in-depth study of the available measurement scales to measure for technophobia. The study included men and women, aged between 25 and 35 years, of higher socio-economic classes, residing in the Northern Johannesburg regions of South Africa. Gender differences in levels of technophobia are studied in relation to three different technologies (computers, DSLR cameras and home automation technology) in order to compare gender differences towards technologies at different stages of the diffusion curve. Future research avenues regarding studies in to technophobia are also presented. The results indicate that traditional differences between genders towards technology still exist amongst South African consumers. Women continue to experience higher levels of technophobia towards new technology than men. However, the degree of these differences changes, depending on the technology used. Regarding why these gender differences may occur, levels of optimism, risk taking and cognitive involvement between genders were measured. In general, the results indicate that traditional gender differences towards technology continue to exist in South Africa. Thus, although marketers may assume that in the modern digital age, men and women are consuming electronics in the same manner, this study shows that this is not necessarily the case, and as a new product is introduced to the market, marketers need to employ differentiating strategies in order to target both men and women successfully. By tailoring the manner in which technology is advertised and shared to the female consumer, marketers are better able to capture this more ‘technophobic’ consumer. The advertising of technologies exasperates the gender divide by confirming established sex role stereotypes, and managers need to learn to differentiate and cater for both genders when advertising technology products. This study illustrates that the degree of technophobia women possess towards technology depends on the technology and its ‘inherent gender bias’ and marketers need to adapt their communications according to the technology being sold. Marketers in the electronics industry cannot have a ‘one-hat-fits-all’ assumption of women and technology, and need to analyse the ‘technology fit’ and communicate it to the market accordingly. By uncovering the social reasons why gender differences continue to exist, advertisers can use these inherent gender differences to test and design advertisements that improve female beliefs about the technology. Marketers are encouraged to experiment with different communication strategies that improve inherent beliefs based on social norms. This study found that women are less optimistic than men, exhibit higher levels of risk aversion, and higher cognitive-processing than men when considering technology purchases. The greatest challenge in stimulating the adoption of high-technology products is the perceived risk that a consumer undergoes when making a purchasing decision. Increasing levels of consumer resistance are also attributed to the sheer volume of new information in the digital era and managers thus need to employ simplifying strategies in order to help break through the messaging clutter and alleviate the information overload that the consumer is experiencing. Managers need to find a balance between being seen as innovative market leaders, and successfully introducing the technology at a pace that invites consumer adoption and acceptance. This study provides strong empirical support for managers attempting to successfully target technology products to men and women. By uncovering gender differences in the way that one reacts to technology, one is better able to understand the consumer and marketing efforts are strengthened. This study not only sheds some light on consumer attitudes, feelings and reactions to new technologies, but it also provides important insight into how men and women accept technology in the market. / Dissertation (MCom)--University of Pretoria, 2011. / Marketing Management / MCom / Unrestricted

The diffusion of biogas technologies in the Brazilian context : A comparative case study in two Brazilian states

Zanatta, Hanna Guimarães January 2020 (has links)
Brazil is one of the largest biomass producers in the world, thus it has a huge potential for biogas production across all its territory. Nowadays, biogas production remains largely unexplored, representing just a small fraction of its potential. The adoption of biogas technologies has grown over the past years, but it is unevenly distributed across Brazilian states. This master thesis investigates the conditions under which the widespread diffusion of biogas technologies can be enabled in the Brazilian context by looking at the factors that influence the adoption of biogas technologies and why it differs across the Brazilian territory. Technological innovation systems (TIS), societal embedding, and diffusion of innovation theory are combined in the theoretical framework to create a broad understanding of the diffusion process of biogas technologies in Brazil. While TIS focusses on what are the functions been performed within the system, Societal embedding contributes to the understanding of why technological diffusion may not happen in the same way in different regions and how technologies are rooted in society. Diffusion of innovation theory adds to the importance of individual choices and strategies in the adoption of technologies. A comparative case study was design between the states São Paulo and Paraná. 16 semi-structured interviews served as the main research instrument with the support of document studies. When looking at the factors that could impact the adoption of biogas technologies the presence of specialized actors that can offer technical support to the implementation of projects locally proved to be positive considering that biogas technologies are still novel in Brazil. The unreliability of the energy grid in rural regions also favours the adoption of biogas technologies for electricity generation in agriculture properties that can combined waste treatment with energy security. Access to financial and human resources is still the largest barrier for the diffusion of biogas technologies. Financial institutions are at large unprepared to offer good conditions for the implementation of biogas projects, mainly because they do not understand the singularities of these projects. The adoption of biogas technologies in the case studies was mainly dictated by the economic activities in place, which shaped the view on biogas technologies. The complexities of the regulatory environment in Brazil could explain why electricity generation is still the main application of biogas technologies as the electricity market is regulated at national level while gas markets are the responsibility of individual states. When biogas technologies are portraited as a tool for sustainable development, other advantages of these technologies are highlighted – environmental and social benefits such as waste treatment and job creation – creating a better claim for biogas technologies which could boost adoption.
