Objective: To develop a new bioinformatic tool based on a data-mining approach for extraction of the most infor-mative proteins that could be used to fred the potential biomarkers for the detection of cancer. Methods: Two independent datasets from serum samples of 253 ovarian cancer and 167 breast cancer patients were used. The samples were examined by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS). The datasets were used to extract the informative proteins using a data-mining method in the discrete stationary wavelet transform domain. As a dimensionality re-duction procedure, the hard threshoiding method was applied to reduce the number of wavelet coefficients. Also, a distance measure was used to select the most discriminative coefficients. To find the potential biomarkers using the selected wavelet coefficients, we applied the inverse discrete stationary wavelet transform combined with a two-sided t-test. Results: From the ovarian cancer dataset, a set of five proteins were detected as potential biomarkers that could be used to identify the cancer patients from the healthy cases with accuracy, sensitivity, and specificity of 100%. Also, from the breast cancer dataset, a set of eight proteins were found as the potential biomarkers that could separate the healthy cases from the cancer patients with accuracy of 98.26%, sensitivity of 100%, and specificity of 95.6%. Conclusion: The results have shown that the new bioinformatic tool can be used in combination with the high-throughput proteomic data such as SELDI-TOF MS to find the potential biomarkers with high discriminative power. 相似文献

The provision of banking services on the Internet (e-banking) is growing but there is a lack of research related to the organisational issues involved in its adoption. This paper brings theory and practice together by synthesising the existing literature with real-life experience of a UK bank. Two questions motivated this research. First, what is the experience of organisations in adopting e-banking? Second, what are the organisational factors which are critical to the success in e-banking adoption? A case study research approach was used to investigate organisational critical success factors in e-banking adoption at The Woolwich bank. The factors found to be most critical for success in e-banking included: understanding customers, organisational flexibility, availability of resources, systems security, established brand name, having multiple integrated channels, e-channel specific marketing, systems integration, systematic change management, support from top management, and good customer services. We concluded that banks need to implement considerable organisational changes in order to web-enable themselves. The main focus of their e-commerce strategy should be to integrate the e-banking channel with other service delivery channels to maximise benefits. 相似文献

The effect of sodium oxalate and methionine supplementation on stone-related constituents of urine was studied in 18 adult
male guinea pigs. Their serum and tissue chemistry and histological changes in urinary tract and liver were also studied.
The calciuretic effect of methionine was blocked by oxalate. The decrease in uric acid and citric acid, caused by oxalate,
was offset by methionine. Oxalate-induced crystalluria and calcium and oxalate deposition in kidney tissue were lessened by
methionine.
Administration of Varuna, an indigenuous drug, to oxalate and methionine-supplemented animals prevented either totally or
partially most of the urolithogenic effects of oxalate and methionine. 相似文献

Increases in high school graduation requirements are prompting interest in the consequences for students, taxpayers, and educators. This study examines the experiences of New York State school districts that increased student participation between 1992 and 1996 in a statewide testing program that historically has been designed for college-bound students. The study includes statistical comparisons based on the universe of school districts in the State as well as the results of an intensive set of selective case studies. The results show that many different types of districts moved to increase participation levels during the study period and that increases in participation levels were associated with (a) modest declines in the percentage of students passing the exams; (b) unchanged drop-out rates; (c) increases in spending that were similar in magnitude to increases found in districts with little or no increase in participation; and (d) increases in professional staffing levels in core instructional areas. Implications for policy are explored. 相似文献

ABSTRACTThis study proposes a classification framework for conflict journalism with respect to its potential for conflict escalation and de-escalation in Pakistan—a country marred by a number of deadly conflicts. While building on the existing literature, the study proposes the varying levels of intensity of a conflict and the resulting escalatory and de-escalatory coverage as important factors in the process. Through content analysis and focus group discussion, it was found that de-escalatory coverage is inversely proportional to the intensity of a conflict in terms of its perceived threats to national security. Secondly it was found that the coverage was spread across a range of thematic frames though certain perspectives got more prominence as compared to others. Noting the variations in the presence of peace journalism, the study concludes that critical pragmatic approach to peace journalism is better suited to address queries relating to its theory and practice than other approaches because it accommodates the retention of peace as a value and at the same is pragmatic and hence honors the requirements of journalistic profession. 相似文献

The mobility of African students beyond national territories has become common worldwide. However, the underlying reasons motivating students to leave their countries of origin in pursuit of higher education in other developing nations and why these factors are important have not been fully explored. This study attempts to explore why and how African students travel to the United Arab Emirates for higher education. A push-pull factor theory of the international student’s choice of destination is developed to identify factors influencing the choices made by these students. The analytic hierarchy process is used to examine the relative importance of these factors. The findings of this quantitative study indicate that learning environment and geographic proximity are the two most important factors for African students, while other factors have a moderate impact. The findings contribute to a deeper and more comprehensive understanding of the needs and choices of existing and potential students from this continent, with a view to applying a segmentation approach to attract these students. 相似文献

Australian education service provision includes the delivery of quality educational programmes to rural and remote living children. However, according to their parents, many children with developmental disabilities (such as Down Syndrome and Autism Spectrum Disorders) who are living in rural country areas in New South Wales (NSW) still do not have access to an acceptable education programme. This study aimed to use quality of life factors via a family quality of life scale to explore 51 parents’ experience of educational service provision for their children with developmental disabilities in rural NSW. The results indicated that successful engagement with the school system is strongly affected by the views, assumptions, expertise and prejudices of teaching and care professionals. Further research into how local educational service providers may assist rural Australian families with a child with IDD in rural and remote locations is warranted. 相似文献

Nostalgic Emotional Appeals for Smoking Prevention 总被引:1,自引:1,他引:0
Nostalgia-evoking messages are used to promote consumer products, but their use for encouraging healthy behaviors is not well understood. This study examines the use of nostalgia as an emotional appeal to influence attitudes and reduce smoking behavior. The study hypothesized that exposure to a nostalgic public service announcement (PSA) will result in (a) more negative attitude toward smoking; and (b) increased intention to limit smoking, relative to a control. Participants exposed to the nostalgia-evoking PSA expressed more negative attitudes toward smoking and stronger intentions to limit smoking than did participants exposed to nonnostalgic messages. The findings suggest nostalgic appeals as a promising strategy for smoking prevention messages. 相似文献
