Breast cancer rehabilitation: a mixed method inquiry of physical recovery and lived experiences

Dobbin, Karen 14 January 2014 (has links)
The purpose of this mixed method study was to determine the extent of physical problems, rehabilitation needs, and cancer rehabilitation experiences after breast cancer treatment. Women diagnosed with breast cancer were surveyed to examine physical morbidities, disability, and quality of life. An interpretive descriptive approach was used in the conduction of a focus group. The percentage of women experiencing physical problems after breast cancer treatment was high, physical disability was low and there was a moderately high quality of life. Despite the high report of physical problems, less than half received physical rehabilitation. Themes from the focus group data were difficulty in finding clear/consistent information, financial issues and the need for integration of cancer rehabilitation services. This research adds to the better understanding of cancer rehabilitation needs and practices and may be used to improve the delivery of cancer rehabilitation services to address the physical needs of breast cancer survivors.

User participation and user satisfaction in information systems development

Bokhari, Rahat Hussain January 2001 (has links)
Information Systems (IS) are being developed and used in organizations to achieve their business goals and to enhance organizational effectiveness. The rate of systems success is questionable. One of the causes of IS failures might be user dissatisfaction with the systems. The success of an Information System is difficult to measure directly, so user satisfaction and system usage are frequently used as surrogate measures of system success. User participation in IS development has been advocated to achieve user satisfaction with the system and consequently system success. Past research findings about the effect of user participation on user satisfaction leading to system success are mixed and inconclusive. Past research has not been successful in showing whether user participation in IS development is necessary or not. So further research in this respect is justifiable. This thesis investigated the effect of user participation/involvement on user satisfaction. The effect of user expectations, and user-developer effective communications on user satisfaction has also been explored. A research model was proposed to proceed with this research. Meta-Analysis was carried out to investigate the relationship between user participation, user expectations and user-developer effective communication each with user satisfaction respectively. This thesis found some relationship of these factors with user satisfaction. The strength of the relationship (i. e. correlation 'r') was found to be 'medium' but not large'. The results also show that user involvement has a larger correlation with user satisfaction as opposed to user participation. The findings not only lead to the conclusions that user participation/involvement, user expectations, and user-developer effective communication have positive relationship with user satisfaction, but also contribute to the existing alternative views among IS researchers. The relationship between system usage and user satisfaction was found to be positive and of 'medium' strength and contrasts with the prevailing view that no correlation exists between them. So research findings are not only useful to resolve controversies that exists in past research but also lead to conclusions that user participation may contribute towards successful IS development and consequently user satisfaction with IS. Further, the causes of the emergence of unrealistic user expectations are explored and suggestions for future research are made.

Investigating consumer adoption, usage and impact of broadband : UK households

Dwivedi, Jogesh Kumar January 2005 (has links)
Despite a large investment, the majority of countries especially the UK demonstrate a slow adoption of broadband. In order to enhance the adoption and use of broadband this research examines the factors influencing the decisions of household consumers. This research aims to address the two main areas of concern: first, to investigate consumer-level factors affecting the adoption of broadband in UK households; and second, to understand the usage of broadband and its impact upon household consumers in the UK. This research adopted a quantitative approach that was executed in the following steps. First, it developed a conceptual model by selecting and justifying relevant constructs from appropriate theories and models related to technology adoption, usage and impact. Second, it operationalised the constructs by developing and validating the research instrument by employing the content validity, reliability and construct validity approach. Finally, it empirically validated and refined the conceptual model by employing a survey research approach. The findings suggested that all the constructs included in the conceptual model, except knowledge, significantly influence the consumers when adopting broadband in a UK household. The significant constructs include relative advantage, utilitarian outcomes, hedonic outcomes, primary influence, facilitating conditions resources and self-efficacy. The rate and variety of Internet usage is significantly higher for broadband consumers than narrowband ones. It was also found that significantly more numbers of broadband consumers perceived changes in time allocation patterns on various daily life activities than narrowband ones. This research contributes towards theory, practice and policy. The contribution of this research towards theory is that it integrates and determines the appropriate information systems (IS) literature in order to enhance knowledge of technology adoption from the consumers' perspectives. An added contribution to theory is the development and validation of a research instrument that future studies can utilise to examine broadband and other similar technologies in household context. Considering the slow adoption of broadband, this research also provides implications for policy makers and the providers of broadband in order to encourage and promote homogenous adoption and usage.

Electronic commerce adoption among manufacturing SMEs in Malaysia

Thi, Lip S. January 2006 (has links)
It is widely acknowledged that electronic commerce presents a significant opportunity for Small- Medium-sized Enterprises (SMEs) to compete alongside larger enterprises. For SMEs in the developing world in particular, the opportunities afforded by electronic commerce for competing in a global marketplace, are also attractive. However, it has also been observed that electronic commerce poses a considerable challenge for SMEs, particularly with regard to the decisions that must be made about which of the available electronic commerce applications to adopt and to integrate into existing business operations. A number of studies have been conducted to investigate the adoption of electronic commerce by SMEs. These studies have tended to view electronic commerce adoption in terms of a dichotomous outcome: either e-commerce is adopted, or it is not. Such studies give little indication of the diffusion, or extent of usage, of individual e-commerce applications. The aim of this study was to address this gap in existing research by investigating both the level of adoption and extent of usage of e-commerce applications. In so doing, the study draws on research in the area of innovation diffusion theory. The focus of the study is on manufacturing SMES in Malaysia, and considers their use of B2B (Business-to-Business) e-commerce. The specific objectives of the study were to measure and characterise B2B e-commerce adoption and extent of usage among manufacturing SMEs in Malaysia; to identify factors associated with the adoption of B2B e-commerce in Malaysian SMEs; and to determine the impacts of that adoption.

Exploring Codon-Anticodon Adaptation in Eukaryotes

van Weringh, Anna 12 October 2011 (has links)
tRNA genes have the fundamental role of translating the genetic code during protein synthesis. Beyond solely a passive decoding role, the tRNA pool exerts selection pressures on the codon usage of organisms and the viruses that infect them because processing codons read by rare tRNAs can be slow or even erroneous. To better understand the interactions of codons and anticodons in eukaryotic species, we first investigated whether tRNAs packaged into HIV-1 particles may relate to the poor codon usage of HIV-1 genes. By comparing the codon usage of HIV-1 genes with that of its human host, we found that tRNAs decoding poorly adapted codons are overrepresented in HIV-1 virions. Because the affinity of Gag-Pol for all tRNAs is non-specific, HIV packaging is most likely passive and reflects the tRNA pool at the time of viral particle formation. Moreover, differences that we found in the codon usage between early and late genes suggest alterations in the tRNA pool are induced late in viral infection. Next, we tested whether a reduced tRNA anticodon pattern, which was called into question by predicted tRNA datasets, is maintained across eukaryotes. tRNA prediction methods are prone to falsely identifying tRNA-derived repetitive sequences as functional tRNA genes. Thus, we proposed and tested a novel approach to identify falsely predicted tRNA genes using phylogenetics. Phylogenetic analysis removed nearly all the genes deviating from the anticodon pattern, therefore the anticodon pattern is reaffirmed across eukaryotes.

Seniorer och internet : En studie om hur PROs medlemmar använder sig av internet

Brundin, Hanne, Norrhäll, My January 2013 (has links)
Since the Internet was introduced, it has taken over faster than anyone was ever expected it to do. It has taken over how we, humans, today live our life and is expected to accomplish our errands, such as paying our bills, ordering clothes and looking up information about travelling. With that said it is important to remember and have in thought that not everyone has the knowledge and skills to use the Internet, this because of the extreme development that the Internet brings. As mentioned above there is one group of people that has been called the “forgotten group” when it comes to the expansion of Internet, and those are the seniors. Most of the seniors today have difficulties using the Internet due to either lack of knowledge or due to the size of the text on the websites, as well as the different color combinations. Since the seniors today have special needs on how to easily use a website, they are forgotten since most websites aren’t developed for seniors. However, sometimes appearances are deceiving and that is what this study has shown us. By questionnaire and interview study, the result of this study has showed us that the majority of the informants do use Internet, but they have special needs when it comes to the design on a website, and that includes color combinations, sizes of the text as well as on how to navigate from one page to another.

The delicate balance of Internet banking and bricks and mortar offices : a study on bank services offered in Visby

Ali, Yasir January 2010 (has links)
Internet banking has an impact on banking performance as well as customer’s daily life. Customers are getting more used to use Internet banking services because the Internet is so popular and common available, it is more convenient and comfortable for customers to use banking services on the Internet. Hereby Internet banking also helps to improve banking service and increasing banks profitability by reducing costs. It also increases the overall value of the banks services by providing convenience, reliable, faster, cheaper services. The purpose of study is to find out which services customer prefers to execute the Internet bank and which services customers prefer to execute through branch office and based on this, what combination of services are desirable for banks customers in Visby. Finding shows that young and educated people are more frequently users of Internet banking for balance inquiry and for viewing the transaction history of his/her account. For some services customers prefer to visit branch office when opining a new account, deposit money, insurances service and loan activities. Banks encourage their customers to use online services but there is need that there are some activities that customer must go to the branch office.

High frequency errors in KFL and pedagogical strategies

Shin, Seong-Chul, School of Modern Language Studies, UNSW January 2006 (has links)
The problematic areas of the teaching of Korean as a foreign language have been largely neglected in the past. Few studies combine the following three aspects: 1) an examination of learner Korean; 2) the provision of substantial linguistic and pedagogical explanations; and 3) the devising of teaching or learning strategies based on empirical evidence. By studying KFL learners and their language production, insights can be gained relating to the learning of KFL and instructors will be able to provide appropriate corrective measures. This study investigated errors produced by KFL learners, focusing primarily on high frequency orthographic, lexical and grammatical errors in written language production. The study attempts to identify key areas of difficulty in learning Korean, to investigate the possible cause of difficulties and to provide more adequate information for the teaching and learning of KFL. To this end the study uses two classes of textual data and employs both statistical and descriptive analyses. At an orthographic level the study has identified four main error categories: 1) mismatch in three series consonants, 2) mismatch in vowel sounds, 3) misuse of nasals and laterals, and 4) omission and addition of ???h???. Overall the cause of key error types correlates strongly with the differences in sound quality and sound patterns between Korean and English, with some intralingual features. At a lexical level, the study found nine types of errors including 1) semantic similarity, 2) lexical misselection and 3) overgeneralization. The findings suggest that learners have a great deal of difficulty in differentiating lexical items with similar meaning and in selecting words appropriate to particular contexts or situations. As for grammatical errors, the study identified the five most active error categories, which made up more than 80% of the total grammatical errors. An overwhelming majority of grammatical errors and case particle errors in particular were errors of substitution. Many high frequency grammatical errors had distinctive triggering factors such as particular types of verb and sentence construction. The findings of the study have several pedagogical implications. First, there are key common errors for English L1-KFL learners and these common errors need increased linguistic and pedagogical attention. Secondly, the results reinforce the need to pay more active attention to the usage of the main case particles, along with the triggering constructions causing substitutions. Thirdly, the findings suggest that different types of analysis should be done in order to facilitate a plausible description of the problematic KFL items. The study argues that despite being problematic, the items discussed in this thesis are learnable and worthy of being taught with explicit or intentional strategies and that there is a need for pedagogically effective and adequate instructional input to maximize the potential of the learner???s language development in Korean.

Effectively capturing user sessions on the Web using Web server logs

Caldera, Amithalal, University of Western Sydney, College of Science, Technology and Environment, School of Computing and Information Technology January 2005 (has links)
The usage of Web sites has been of interest to Web administrators and researchers ever since the Web started. Analysis of Web site usage data helps to understand the behaviour of its users, which is very important, as many important decisions can be made based on it. The user behaviour may be deduced by knowing all the activities each user does from the time s/he starts a session on the Web site until s/he leaves it, which is collectively called a user session. As Web server logs explicitly record the browsing behaviour of site users and are readily and economically available, this thesis explores the use of Web server logs in capturing user sessions on Web. In order to protect users’ privacy, the standard Web server logs in general do not record the user identities or similar measures to uniquely identify the users. This thesis concentrates on heuristic strategies to infer user sessions. The heuristics exploit the background knowledge of user navigational behaviour recorded in the standard Web server logs without requiring additional information through cookies, logins and session ids. They identify relationships that may exist among the log data and make use of them to assess whether requests registered by the Web server can belong to the same individual and whether these requests were performed during the same visit. Researchers have proposed several heuristics, which were adversely affected by proxy servers, caching and undefined referrers. The thesis proposes new heuristics, which effectively address all the limitations, thus extending the work in this field. It also introduces a set of measures to quantify the performance of the heuristics and uses them to investigate their efficiency based on logs from three Web sites and makes recommendations for the Web sites to devise their own heuristics. The investigation has shown satisfactory results and the new heuristics are applicable to wider range of Web sites. / Doctor of Philosophy (PhD)
