Progress in computer technology over the last four decades has been spectacular, driven by Moore's law which, though initially an observation, has become a self-fulfilling prophecy and a boardroom planning tool. Although Gordon Moore expressed his vision of progress simply in terms of the number of transistors that could be manufactured economically on an integrated circuit, the means of achieving this progress was based principally on shrinking transistor dimensions, and with that came collateral gains in performance, power-efficiency and, last but not least, cost. The semiconductor industry appears to be confident in its ability to continue to shrink transistors, at least for another decade or so, but the game is already changing. We can no longer assume that smaller circuits will go faster, or be more power-efficient. As we approach atomic limits, device variability is beginning to hurt, and design costs are going through the roof. These are impacting the economics of design in ways that will affect the entire computing and communications industries. For example, on the desktop there is a trend away from high-speed uniprocessors towards multi-core processors, despite the fact that general-purpose parallel programming remains one of the greatest unsolved problems of computer science. If computers are to benefit from future advances in technology then there are major challenges ahead, involving understanding how to build reliable systems on increasingly unreliable technology and how to exploit parallelism increasingly effective, not only to improve performance, but also to mask the consequences of component failure. Biological systems demonstrate many of the properties we aspire to incorporate into our engineered technology, so perhaps that suggests a possible source of ideas that we could seek to incorporate into future novel computation systems?

The synergetic development of art and technology is a common trend for the development of aesthetics and computer technology, so it is imperative to introduce computer technology to aesthetic education in Chinese colleges. This paper reviews the problems and dilemma of college aesthetic education in China and proposes to reform college aesthetic education by information technology. Focusing on image aesthetics, the author analyzes the image aesthetic features with computer algorithms and demonstrates the superiority of computer algorithms in optimizing image and enhancing aesthetic beauty. The proposed method can overcome the dilemma of aesthetic education in Chinese colleges and realizes preliminary informatization reform of college aesthetic education. The research findings have theoretical guiding significance for the modernization of aesthetic education in colleges and the comprehensive development of college students.

Purpose: To summarize how computer technology influenced immigrant families' adaptation to life in the United States. Design: Critical ethnography. Methods: Data were collected from 1998 to 2000 from 13 parents and 16 children from nine Taiwanese immigrant families using semi-structured interviews and a questionnaire. Narrative analysis was used with interview data. Findings: Participants faced the demands of language proficiency, economic survival, loss of social networks, and social disconnection during resettlement. computer technology provided participants with new occupational opportunities and strategies to overcome the barriers and stress created by resettlement. Internet and E-mail access greatly facilitated these participant families' adaptation. Conclusions: Study findings warrant further exploration to assess how new computer technology promotes immigrant families' adaptation and alleviates stress associated with resettlement, including information about their health and health care.

The aim of this project is to further examine the construct of domain identification (i.e., a person's positive phenomenological experiences with, and perceived self-relevance of, a domain), specifically as it applies to computer technology (CT). The authors model a known measure of math identification to first develop a measure of CT identification. The authors then test whether the new CT identification measure could uniquely explain the relationship between individuals' gender and CT career pursuit, above and beyond math identification. Finally, the authors examine the relationships between men's and women's CT domain identification, their perceptions of the CT field, and their interpersonal orientation to determine whether existing relationships among these variables might explain individuals' willingness to consider a number of CT- and non-CT-related fields.

This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher-students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants' instruction with computer technology was (Teacher) initiation-(Student and Teacher) response sequences-(Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers' learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers' own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.

The computer Anxiety Scale (CAS) is a measure of perceptions by individuals of their anxiety in different situations toward computers. The CAS was developed a number of years ago before computer technology became such an integral part of life. Covariance modeling techniques were used to examine whether the originally proposed construct of computer anxiety has undergone change in a sample of German college students. Results provide support for the invariance of the factor structure of the scale.

This paper uses computer technology combined with regression model to analyze the risk factors ofchildren with sepsis, determine the relevant factors and establish a corresponding early warning modelof sepsis, and then verify the clinical application value of the regression model. The paper collected severeinfections and sepsis in children who came to our hospital from 2014 to 2018, including 129 patientswith infection and 86 patients with sepsis. The general conditions, clinical symptoms, laboratory testsand other factors were used. Analysis, to identify the risk of infection development into sepsis, and useLogistic regression model combined with computer technology to construct an early warning model ofsepsis. The experimental results show that early warning of sepsis is closely related to skin spots, platelets, procalcitonin, creatinine and international normalized ratio. The experiment demonstrates that the earlywarning model has higher sensitivity and specificity, and has higher accuracy for predicting whetherinfection develops into sepsis in advance, and has certain clinical value.

This study investigated influences on employee self-efficacy of computer technologies resulting from computer training programs that were intended to meet individual and organization objectives for university personnel. Subsequent to training, an assessment of employee computer technology self-efficacy was necessary for determining self-efficacious duration and the usefulness of technical education. A descriptive survey design was used to gather data from a population of 2597 university employees. Results indicated employee computer technology self-efficacy levels remained stable for a 2.5-year period. In addition, select subscales of the variables previous classroom computer training and computer use required on the job predicted computer technology self-efficacy. Frequency of computer use, home computer use, and training responsibility were also noted to influence the transfer of training process as it pertains to computer technology self-efficacy. Interaction relationships were also discovered among certain disciplines of computer use and degree of computer use. Implications of the study are relevant to employee placement and workplace computer education needs. (C) 1999 Elsevier Science Ltd. All rights reserved.
