Medical knowledge discovery systems: data abstraction and performance measurement     

Albert L?HarrisEmail author  Charlie C?Chen  William J?Perkins 《知识管理研究与实践》2004,2(2):95-102

Knowledge discovery systems can be traced back to their origin, artificial intelligence and expert systems, but use the modern technique of data mining for the knowledge discovery process. To that end, the technical community views data mining as one step in the knowledge discovery process, while the non-technical community seems to view it as encompassing all of the steps to knowledge discovery. In this exploratory study, we look at medical knowledge discovery systems (MKDSs) by first looking at three examples of expert systems to generate medical knowledge. We then expand on the use of data abstraction as a pre-processing step in the comprehensive task of medical knowledge discovery. Next, we look at how performance of a medical knowledge discovery system is measured. Finally, the conclusions point to a bright future for MKDSs, but an area that needs extensive development to reach its full potential.  相似文献

African universities and the state: Prospects for reform in Senegal and Uganda     

Thomas Owen Eisemon  Jamil Salmi 《Higher Education》1993,25(2):151-168

Uganda's Makerere University and the University of Dakar in Senegal were for many years after independence among Africa's premier universities. Today, their facilities have visibly deteriorated and the quality of instruction the institutions provide is seriously threatened — the consequence of political and economic turmoil combined with persistent underfunding. If higher education remains supply-driven without reference to available resources, the problems of Makerere and the University of Dakar can only increase and become even more unmanageable. The governments of Senegal and Uganda are being encouraged by donors to undertake reforms to revitalize the university sector. However, it will not be possible to reform financing of public higher education, or to carry out many other reforms, unless the universities have more administrative and financial autonomy. Strategies for reforming higher education systems in these countries are proposed requiring a shift from government participation in the governance of public universities and in matters affecting their enrolments and utilization of resources to more indirect forms of control. Nevertheless, the policy implications for Senegal and Uganda are very different. In Senegal, measures to increase autonomy must be articulated with a larger role for the state in regulating the flow of students to university, rationalizing the programs of different institutions and restricting students' eligibility for support. In Uganda, there is need for greater government co-ordination of public and private investments in higher education and significant devolution of control of public universities.McGill University, Education and Employment Division, Population and Human Resources Department, The World BankEducation and Employment Division, Population and Human Resources Department, The World Bank  相似文献   

Exploring students’ perceptions of service-learning experiences in an undergraduate web design course     

Sang Joon Lee  Charlie Wilder  Chien Yu 《Teaching in Higher Education》2018,23(2):212-226

Service-learning is an experiential learning experience where students learn and develop through active participation in community service to meet the needs of a community. This study explored student learning experiences in a service-learning group project and their perceptions of service-learning in an undergraduate web design course. The data showed that the service-learning project helped students learn the course material, feel more connected to the surrounding community, and improve their communication and problem-solving skills for their careers. The participants appreciated the opportunity to work with the service-learning partner and will be likely to look for more opportunities to get involved in the community. Time constraints, group work, working with real clients, and technical limitations were reported as major challenges in the group project.  相似文献   

Effect of women science career role models on early adolescents' attitudes toward scientists and women in science     

Walter S. Smith  Thomas Owen Erb 《科学教学研究杂志》1986,23(8):667-676

In order to change the attitude of early adolescent female and male students toward scientists and women in science, students in the middle school/junior high grades were exposed over a two months' period to women science career role models as part of their science instruction. This treatment positively affected the students' attitude toward scientists and toward women in science. It is suggested that teachers of science in the middle school/junior high should periodically bring community resource people who use science in their careers to the classroom to act as role models and that women should be included among this group so that the attitudes of both male and female students toward scientists and women in science might be improved.  相似文献   

Perceptions of U.S. Medical Residents Regarding Amount and Usefulness of Sexual Health Instruction in Preparation for Clinical Practice     

Shannon Criniti  Betsy Crane  Mark B. Woodland  Owen C. Montgomery  Sandra Urdaneta Hartmann 《American journal of sexuality education》2016,11(3):161-175

Despite patient demand for sexual health discussions with their physicians, sexuality instruction in residency is often lacking. This exploratory quantitative study assessed the amount and usefulness of sexuality instruction received by a sample of medical residents, as well as the residents' self-perceived readiness regarding addressing sexuality issues. Data were obtained through a self-administered survey with 130 resident respondents. The majority reported receiving little/no formal sexuality instruction. Many indicated that additional sexuality instruction would be useful in their practice. Although the majority reported comfort discussing sexuality, they reported rarely/never initiating these discussions. Recommendations for changes in graduate medical education programming are provided.  相似文献   

Changing thoughts,changing practice: examining the delivery of a group CBT-based intervention in a school setting     

Caoimhe Weeks  Vivian Hill  Charlie Owen 《Educational Psychology in Practice》2017,33(1):1-15

Promoting mental health and well-being for children and young people in the UK has attracted increasing prominence in recent years and has been a focus for government strategy within health and education. Training and practice in educational psychology has increasingly focused on developing skills and expertise to provide therapeutic support within school contexts, at an early stage of need. One approach, Cognitive Behaviour Therapy (CBT), has been heralded as an effective, evidence-based intervention for anxiety. This research examines the factors influencing the outcomes of a group CBT-based intervention, run by an Educational Psychologist (EP), in a school setting. The findings suggest that influential variables included pupil identification, measures of change applied and the role of school staff. It is concluded that EPs can play a key role in increasing access to psychological therapies, alongside considering due caution in relation to the application of traditional clinical approaches in school contexts.  相似文献   

The Effect of Group Orientated Classroom Management Procedures on Individual Pupils     

E. McNamara  A. Harrop  F. Owen 《教育心理学》1987,7(3):157-168

Summary This study was designed to test the hypothesis that group orientated classroom management procedures may achieve their apparent success merely by raising still further the on‐task behaviour of non‐troublesome pupils. To this end, 1812‐13 year old pupils in a secondary school remedial class were observed and their individual levels of on‐task behaviour recorded. The class teacher's use of approval and disapproval was also noted.

Following the collection of baseline data, a modified, simple ‘rules, praise and ignoring’ intervention strategy was implemented, followed by a partial reversal to baseline conditions. Mean class on‐task behaviour was clearly shown to increase from 77% at baseline to 91% during intervention and this was maintained during the partial reversal. Moreover, it was shown that every pupil's on‐task behaviour increased, these increases varying between 3 and 33%, the pupils with the lowest baseline levels making the biggest gains.  相似文献
