The diffusion of joint mother and baby psychiatric hospital admissions in the UK : an historical analysis

Robertson, Karen E. January 2012 (has links)
Background: A key innovation in the provision of inpatient services to facilitate the care and treatment of women with severe postnatal mental illness was the introduction of joint mother and baby psychiatric hospitalisations, where both the mother and baby are admitted to hospital together. This study examined the history of the practice of joint mother and baby admissions across the UK and critically explored the processes relevant to the diffusion of joint admissions and patterns of service development to identify the possible and probable causes for significant differences in service provision across the United Kingdom (UK). Aims: The study examined the documented history of the development of practice of joint mother and baby psychiatric hospital admissions across the UK and in doing so, a) Identified the pattern of service and practice development and the likely reasons for the pattern of the chronology. b) Identified the processes involved in the diffusion of joint mother and baby admissions in the UK, and explored why the practice was sustained (or not). c) Contributed new information to the continued development of innovation diffusion theory and research, and its application to health care service and practice development. Methods: A historical method was used in the study and was reported through the use of historical narrative and analysis. Data was collated from primary and secondary sources of documented evidence which was used to inform the history of joint mother and baby admissions across the UK. Data was analysed using the theoretical framework of diffusion of innovation (Rogers, 2003). Findings: Two versions of the same innovation were identified: joint admissions to side rooms of general adult psychiatric wards or annexed areas of the wards and joint admissions to specialist mother and baby units. Neither version of the practice followed the normal S-curve pattern of adoption in terms of frequency and rate of adoption. After a period of approximately 63 years there are 24 facilities for the provision of joint admissions in the NHS in the UK. The main influencers to the adoption of the practice was perception of risk, social networks internal and external to the NHS, the presence of clinical and political champions to drive the adoption and implementation of the innovation and policy entrepreneurship by clinicians working in the clinical field of perinatal mental health. The development of specific policy, guidelines and in Scotland, legislation, has resulted in a move during the last decade from joint admissions being diffused naturally to side room admissions being actively withdrawn and specialist psychiatric mother and baby units actively being disseminated. There is strong evidence that the diffusion process for specialist mother and baby units is still in motion at the time of reporting. Conclusion: Two competing versions of the same innovation had unusual patterns of diffusion. The influencers identified as relevant to the diffusion patterns of each version of the innovation were essentially the same influencers but they were used in different ways to affect change: rejection of one version of the innovation in favour of adoption of the other. The main influencers on the diffusion of joint admissions changed over the time line of the adoption pattern. Barriers to diffusion included the absence of evidence of effectiveness, the absence of economic evaluation, the position in service divisions of perinatal mental health as a field of practice and the absence of succession planning across professional groups. Recommendations are made for future research.

Evaluating Inductive Electric Road Systems Implementation : A multiple case study in Sweden

Nagarasan, Yuvanesh, Francis Xavier, Kevin Raja January 2020 (has links)
Sustainable transportation solutions are the goal for the future. With the technological shit happening in the transportation market towards electric vehicles, the electric road system (ERS) is a necessary technology required to reach the sustainability goals for the future. While many studies show the role of innovation in a socio-technical landscape, many neglect the diffusion process of the innovation which occurs to create a socio-technical change. The nature of this thesis is an exploratory case study with a qualitative approach. To address the study, a literature review for the diffusion of innovation, its characteristics, multi-level perspective, and technology readiness level (TRL) was presented in order to provide a better understanding and build a foundation for the research. A review of scientific articles regarding the electric road system was performed to provide insights and obtain information on the technology. The data from scientific articles were complemented by interviews from experts regarding electric road systems to obtain an understanding of technology if it was to be implemented in the future in Sweden. The empirics collected were analyzed using the literature framework and conclusions were drawn. Analyzing the data was required to find the factors hindering the technology and if there is a window of opportunity for the technology to exist in the Swedish market. Environmental sustainability has been the driving factor, but the rate of diffusion for the technology will depend on the complexity and the maturity of the technology to function as a whole working system. The study contributes to evaluating the implementation of an inductive electric road system in the Swedish context and if it could be a viable solution in the transportation market. The perspectives of the technology in the Swedish market and the motivation for the solution are discussed. An analytical contribution by evaluating if the technology could exist in the future and insights on the diffusion of the technology into the existing landscape.

Factors that contribute significantly to scrum adoption as perceived by scrum practitioners working within South Africa organisations

Hanslo, Ridewaan 05 1900 (has links)
Text in English / Scrum is the most adopted and under-researched Agile methodology. The research conducted on Scrum adoption is mainly qualitative. Therefore, there was a need for a quantitative study to investigate Scrum adoption challenges. The general objective of this study was to investigate the factors that have a significant relationship with Scrum adoption as perceived by Scrum practitioners working within South African organisations. To achieve this objective a narrative review to synthesise the existing challenges was conducted, followed by the use of these challenges in the development of a conceptual framework. After that, a survey questionnaire was used to test and evaluate the developed framework. The research findings indicate that relative advantage, complexity, and sprint management are factors that have a significant linear relationship with Scrum adoption. The findings are generalisable to the population, and the author recommends that organisations review the findings during their adoption phase of Scrum. / Council for Scientific and Industrial Research (CSIR) / University of South Africa (UNISA) / School of Computing / M.Sc.

The Influence of Social Media on the Tourism Industry: A Content Analysis of Culinary Tourism Brands via Instagram

White, Angela 01 December 2021 (has links)
The tourism industry in the United States is constantly changing and being influenced by social media, specifically Instagram. Culinary brands use Instagram to advertise their restaurants and dishes in a creative, visual way. As a result, Instagram is now being used as a tool by tourists and both potential and current customers to share their dining experiences and find these locations based on the visual appeal. This study provides a content analysis of Instagram account information and photo composition within eight popular culinary tourism destinations by examining the strategies used by the accounts. 50 randomly selected photos were used from eight popular culinary tourism locations. Framing, Uses and Gratifications, and Diffusion of Innovation theories were the theoretical framework for the study. The results of this study indicated key characteristics of some of the most popular culinary tourism destinations on Instagram.

A Stated Preference Study for Assessing Public Acceptance Towards Autonomous Vehicles

Christos Gkartzonikas (5929697) 29 April 2020 (has links)
<div>Technology is rapidly transforming both vehicles and transportation systems. The nature of this transformation will depend on how fast the technology resulting from three related revolutions, those in automated, electric, and shared vehicles, will diffuse. At the same time, the ‘sharing’ economy is growing and affecting mobility in urban areas that includes additional travel alternatives, such as car-sharing services, ride-hailing services, bike-sharing services, and other micro-transit services. It is evident that to prepare for these large-scale operations involving autonomous vehicles (AVs), researchers and transportation professionals need the useful insights on people’s attitudes toward and on acceptance of AVs that can be gained through behavioral experiments. In addition to this, it is also important to understand how the deployment of AVs will impact vehicle ownership and mode choice decisions.</div><div><br></div><div>The goal of this dissertation is to assess the public acceptance of AVs and shared autonomous vehicles (SAVs) via a behavioral experiment (stated preference survey) and offer insights on the potential implications of AVs and SAVs on mode choices. The following four overarching research objectives were formulated: (a) identifying the factors influencing the behavioral intention to ride in AVs; (b) identifying the characteristics of the AV market segments; (c) evaluating the attributes impacting personal vehicle ownership decisions (i.e., decisions to postpone the purchase of a non-AV due to the emergence of AVs); and (d) assessing the factors affecting mode choice decisions after the emergence of autonomous ride-sharing services operated through AVs, and evaluating the corresponding value of travel time savings. The results of each part of the research framework are integrated in the last chapter of the dissertation in order to provide the final conclusions and recommendations of the study.</div><div><br></div><div>To achieve these research objectives, a survey of the general population was distributed online in a major urban area with an advanced multimodal transportation system and captive users of ride-sharing users (Chicago, Illinois) and in an urban area with a more automobile-oriented culture (Indianapolis, Indiana). The survey sample included 400 responses of adults, representative of age and gender on each area. </div><div><br></div><div>One of the contributions of this dissertation is a theoretical model to assess the behavioral intention to ride in AVs that includes components of the theory of Planned Behavior, the theory of Diffusion of Innovation and additional factors derived from the literature while evaluating possible interrelationships between these components. A more holistic approach along these lines can help explain whether the emerging AV technology can diffuse by identifying the factors and key determinants that influence the behavioral intention to ride in AVs. The market segmentation analysis can further provide knowledge of the socio-demographic characteristics of potential AV users and an accurate classification of these groups of potential users in terms of their willingness to ride in AVs. The findings can provide insights into perceptions of and attitudes toward AVs that can help transportation and urban planners, as well as original equipment manufacturers, to prepare for the deployment of AVs by designing marketing strategies to improve people’s perceptions of AVs and increase market penetration.</div><div><br></div><div>Moreover, this dissertation provides a well-documented and easy-to-use framework that can support both planning and policy decisions in urban areas in an era of emergent automated transportation technologies. In urban areas with advanced multimodal transportation networks, the framework can be applied to identify the impact attributes affecting shared mobility in urban settings. In urban areas with a more car-oriented culture, the framework can be applied to explore the potential impacts of the emergence of AVs on personal vehicle ownership patterns. Finally, the survey that was designed to fulfill the goal of this dissertation can be replicated and distributed in metropolitan areas outside the US with more advanced multimodal transportation systems or areas within the US with traditionally higher rates of affinity to innovativeness and areas where AVs have been pilot-tested in real-world road conditions.</div><div><br></div>

Users’ perceptions on security of mobile computing for adoption of e-applications in South Africa

Mapande, Fhatuwani Vivian January 2018 (has links)
M.Tech (Department of Information technology, Faculty of Applied and Computer Science), Vaal University of Technology. / The advancement of technology, particularly in the area of mobile computing, revolutionizes the way business is done in many industries such as the education sector, government sector, financial institutions, retail sector and the way people conduct their daily activities. The current technology provides influential tools for organisations and can significantly influence their operation, structure and approach. The development of mobile computing has created a new innovation for various industries by increasing the availability, frequency and speed of communication between the organisations and the individuals. However, users’ perceptions can play an important role towards the adoption of these new developments. The overriding purpose of this study was to investigate the users’ perceptions on the security of mobile computing in South Africa for adoption of e-applications. The literature review was concentrated on the process of progressive development occurring during the study. To accomplish that goal it became necessary to reach some essential objectives i.e. investigating the users’ perceptions models in literature. For the purpose of the study, it was important to propose a research framework for users’ perceptions on the security of mobile computing with the potential for the adoption of e-applications in South Africa. The research evaluated the proposed framework to establish if there is any relationship between the e-application adoption factors. Furthermore, the hypotheses were tested to determine which factors would influence the adoption of e-applications in South Africa. Technology Adoption Model 2 (TAM2) and Diffusion of Innovation (DOI) provide the theoretical basis for explaining how users perceive e-application services that they access and operate through mobile computing. To achieve that, a quantitative study was conducted with South African residents, with respect to mobile security perceptions; 476 valid questionnaires were received from the participants who were selected non-randomly. Questionnaires were developed from the proposed research framework derived from DOI and TAM2 and the items were adopted from other prior technology adoption studies. Through the use of the survey instrument developed for this study, data were collected in order to address the importance of this study based on the problem statement posed in the first chapter of this dissertation. The valid questionnaires were analysed by using the Statistical Package for the Social Sciences (SPSS), Version 24.0. Reliability analysis, principal component analysis, correlations and multiple linear regression tests were conducted. Among other things this study made sure that ethical considerations are adhered to. The findings revealed positive relationships between perceived usefulness of security mechanisms, perceived ease of use of security mechanisms, subjective norm on security mechanisms, relative advantage of security mechanisms, compatibility of security mechanisms, complexity of security mechanisms, aesthetics of security mechanisms interface and intention to adopt e-applications. Furthermore, subjective norm on security mechanisms was strongly correlated to intention to adopt e-applications, complexity of security mechanisms strongly correlated to perceived usefulness of security mechanisms, relative advantage of security mechanisms and aesthetic of security mechanisms interface strongly correlated to perceived usefulness of security mechanisms. In addition, subjective norm of security mechanisms strongly influence intention to adopt eapplications in South Africa. Also, aesthetics of security mechanisms interface strongly influence both perceived usefulness of security mechanisms and perceived ease of use of security mechanisms. The reason behind it may be interpreted as users nowadays seeing the beauty as the platform to attract and encourage them to use e-applications. Finally, the proposed model analysis and survey evaluation will enable South African organizations to make informed decisions about the use of e-applications services. These findings contribute to a road map for the education sector, government sector, financial institutions, and retail sector as well as to encourage their customers or clients to adopt e-applications.

Adoption of open access publishing for scholarly communication by academic staff at the University of Limpopo

Shoroma, Moritidi Abigail January 2021 (has links)
Thesis (M.A. ( Information Studies)) -- University of Limpopo, 2021 / This study aimed to examine the extent of awareness and the adoption of Open Access (OA) publishing for the purpose of scholarly communication by academic staff at the University of Limpopo (UL). The study was guided by Rogers’ Diffusion of Innovation theory (1) to measure the level of awareness of academics on the availability and use of OA resources; (2) to determine the adoption and usage levels of OA publishing as a platform for information sharing by academics in scholarly communication; (3) to establish academics’ attitudes towards the use of the OA publishing platforms; and (4) to identify perspectives of academic staff with regards to challenges and benefits presented by OA publishing. A dominantly quantitative research approach was adopted using a google forms questionnaire with closed ended questions to collect data from 250 academics at the University of Limpopo. Academics were selected using the systematic simple random sampling method. To ensure the survey instrument’s reliability and validity, the researcher conducted a pilot study through a web-based survey. A descriptive statistics method of the Statistical Package for Social Sciences (SPSS) was used to analyse data. The study established that the majority (82%) of academics were aware of OA publishing platforms. The internet and subject librarians were the main communication channels through which they became aware of OA publishing. The study also found that there was minimal the adoption and usage of OA publishing among academics. Their attitudes towards OA and their perceptions of the benefits and challenges of OA. The general attitudes of academics about OA were positive, signifying the acceptance of this scholarly communication mode. However, some of the challenges encountered in adopting and using OA publishing include slow internet connectivity and access, publication charges by some publishers, lack of skills to publish online, power interruptions, lack of policies on OA, fake and predatory v publishers and OA articles not being peer-reviewed. These were reported as problems that directly or indirectly hinder academics from publishing in OA platforms. The study recommends the institutionalisation of OA publishing at UL to improve research output dissemination. An area for further research will be to establish more insights regarding the feasibility of OA development and possible ways of dealing with article processing fees. Keywords: Open Access publishing, scholarly communication, Academic staff, Institutional Repositories, Rogers’ Diffusion of Innovation theory, University of Limpopo.

#musik – Musikindustrins användande av hashtags och sociala medier

Mattis, Andersson January 2019 (has links)
Denna studie undersöker hur representanter från musikindustrin använder sig av hashtags, sociala medier och vilka effekter hashtags har samt, vilken effekt de skulle kunna ha på deras arbete. Användningen sätts i förhållande till tio redan definierade funktioner av hashtags.Uppsatsens syfte är att bidra till djupare förståelse hur hashtags används och hur dessa kan användas inom musikindustrin. Genom att förtydliga om detta är ett verktyg som kan användas för att lättare sprida information på social media. Detta genomfördes genom en kvalitativ studie och utförandet av semistrukturerade intervjuer med fem representanter från musikindustrin och två respondenter som arbetar inom andra områden, varav en är har forskat på twitter och hashtags och en jobbar med att stärka användningen av digitala verktyg på ett större företag. Detta har sedan blivit granskat genom en induktiv ansats. Frågeställningen har besvarats genom att resultaten från empirin analyserats utifrån teorin.Studien kom fram till att representanterna från musikindustrin i huvudsakligen använde sociala medier och hashtags för att marknadsföra sig själva och sina band. Men Artist 1 använde hashtags mer än Skivbolag 1. Effekterna hashtags hade var både positiva och negativa. Fördelen var att hashtags kunde rikta deras budskap mer exakt och nackdelen var att personer kan ha en negativ bild av hashtags och på sätt bli kritiska till användningen av dem. / This study examines how representatives from the music industry use hashtags, social media and what effects hashtags have, and what effect they could have on their work. The usage is set in relation to ten already defined functions of hashtags.The purpose of the thesis is to contribute to a deeper understanding of how hashtags are used and how these can be used in the music industry. By clarifying whether this is a tool that can be used to more easily disseminate information on social media. This was done through a qualitative study and was conducted by semi-structured interviews with five representatives from the music industry and two respondents as workers in other areas, one of which has been researching twitter and hashtags, and one who is working on strengthening the use of digital tools at a large company. This has since been examined through an inductive approach. The question has been answered by analysing the results of the empirical data based on the theory.The study concluded that the representatives of the music industry mainly used social media and hashtags to market themselves and their bands. But the artist used hashtags more than the record company. The effects of hashtags had been both positive and negative. The advantage was that hashtags were able to target their messages more accurately and the disadvantage was that people could have a negative image of hashtags and thus become critical of their use.
