An analysis of the role of users in the total r&d portfolios of scientific instrument firms     

Francis C. Spital 《Research Policy》1979,8(3):284-296

This paper describes a real-time investigation of the total new product portfolios of nine product departments in the scientific instrument industry. It was found that within these portfolios only a few new products represented a major advance in functional performance. Most new products offered only incremental performance improvement, and many ‘new’ products were direct copies of competitors ' offerings.The scientific instrument innovation process is described in seven stages: recognition of need, invention of solution, prototype development, use in application, precommercial information dissemination, product engineering, and commercialization. In those cases where users were involved in the majority of the first five stages of the innovation process, the innovation was either a major functional improvement or a minor improvement that had not been initiated as a direct response to a competitor's product introduction. Direct copies and minor improvements that were competitive responses are notable for the absence of user involvement in the innovation process.Finally, the decision of a manufacturer to commercialize an innovation was unrelated to the level of user activity in the prior stages of the innovation process.  相似文献   

Growth in Precursor and Reading‐Related Skills: Do Low‐Achieving and IQ‐Discrepant Readers Develop Differently?     

Kimberly J. O&#x;Malley  David J. Francis  Barbara R. Foorman  Jack M. Fletcher  Paul R. Swank 《Learning disabilities research & practice》2002,17(1):19-34

Poor readers who met low achievement and IQ‐discrepancy definitions of reading disability were compared with nonimpaired readers on their development of eight precursor and reading‐related skills to evaluate developmental differences prior to students’ identification as reading disabled. Results indicated no evidence for differences between the two groups of poor readers in the development of the eight skills, with three exceptions. Students in the IQ‐discrepant group demonstrated greater growth in letter sound knowledge, greater mean performance in visual‐motor integration at the beginning of first grade, and greater deceleration in rapid naming of letters. When compared to the nonimpaired group, low‐achieving readers demonstrated poorer performance and development in all skills, while the IQ‐discrepant readers demonstrated poorer performance and development in phonemic awareness, rapid naming of letters and objects, spelling, and word reading. The largely null results for comparisons between the two groups of poor readers challenges the validity of the two‐group classification of reading disabilities based on IQ‐discrepancy.  相似文献   

Early childhood teachers' views of nature of science: The influence of intellectual levels,cultural values,and explicit reflective teaching     

Valarie L. Akerson  Cary A. Buzzelli  Lisa A. Donnelly 《科学教学研究杂志》2008,45(6):748-770

This study tracked the influence of explicit reflective instructional methods on cultural values, ethical and intellectual development, and the relationship of these with preservice teachers' views of nature of science (NOS). The researchers used the Views of Nature of Science Form B (VNOS B) to describe NOS views, the Learning Context Questionnaire (LCQ) to classify preservice teachers' ethical and intellectual positions using Perry's scheme, and the Schwartz Values Inventory (SVI) to measure preservice teachers' cultural values. The interventions took place in two concurrent courses: a science methods course, and a foundations of early childhood course. The science methods course explicitly emphasized NOS throughout the semester, and the foundations of early childhood course reinforced these ideas through cultural activities that stressed empirical evidence. Analysis of data showed relationships between preservice teachers' Perry positions and responses on the VNOS B with those at higher positions exhibiting more informed NOS views. Relationships between preservice teachers' NOS views and their cultural values were identified, such as those at the dualism position holding achievement more highly for scientists than those at other Perry positions. The values preservice teachers held personally were different from those they held as important for scientists. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 45: 748–770, 2008  相似文献   

Teacher education for inclusion in Europe     

Verity Donnelly  Amanda Watkins 《Prospects》2011,41(3):341-353

Teacher education issues are high on the policy agenda across Europe. The United Nations Convention on the Rights of People with Disabilities (2006) is gaining momentum and providing a force for change, supported by many communications both internationally and at European level that recognize how central education is in efforts to develop a more equitable society. In moving towards a more inclusive education system, there is a need to train all teachers to meet the diverse needs of all learners in their classrooms and to work collaboratively with colleagues. Drawing on key documents, this article outlines the policy context and reviews the available evidence supporting the move towards teacher education for inclusion across Europe. It presents the work of the European Agency for Development in Special Needs Education, to highlight some of the opportunities and challenges within its member countries in addressing teacher education for inclusion.  相似文献   

Validation of MET estimates and step measurement using the ActivPAL physical activity logger     

Harrington DM  Welk GJ  Donnelly AE 《Journal of sports sciences》2011,29(6):627-633

The purpose of this study was to determine the validity of the metabolic equivalent (MET) equation and step rate function of the ActivPAL? physical activity logger in a group of females. Using a standard treadmill protocol, 62 females aged 15-25 years walked on a treadmill at speeds between 3.2 and 7.0 km · h(-1) while wearing an ActivPAL. Oxygen consumption was measured using expired gas analysis at each speed and METs for each speed were estimated based on each participant's own resting metabolic rate. A sub-set of 18 participants also wore an Actigraph. Results showed that the in-built equation in the ActivPAL significantly underestimated (P < 0.001) METs under treadmill conditions at higher intensities. The ActivPAL equation is based on step rate yet the relationship between counts and measured METs (r = 0.76; P < 0.001) is stronger than that between steps and measured METs (r = 0.59; P < 0.001). Both the ActivPAL and Actigraph step functions showed no significant difference (P > 0.05) to video recorded step rate except at the slowest walking speed where the Actigraph significantly underestimated steps (P < 0.05). The development of a new equation based on the counts-METs relationship that includes a variety of speeds and activities would be useful. The ActivPAL step function performs better than the Actigraph at the slowest walking speed under treadmill conditions.  相似文献

A process for the critical analysis of instructional theory     

Jay A. Bostwick  Isaac Wade Calvert  Jenifer Francis  Melissa Hawkley  Curtis R. Henrie  Frederick R. Hyatt  Janeel Juncker  Andrew S. Gibbons 《Educational technology research and development : ETR & D》2014,62(5):571-582

Some have argued for a common language in the field of instructional design in an effort to reduce misunderstandings and simplify a multitude of synonymous terms and concepts. Others feel that this goal is undesirable in that it precludes development and flexibility. In this article we propose an ontology-building process as a way for readers to compare and analyze terms and concepts across theories. This process entails the development of categories that emerge from the literature, and the comparison of theories across categories. Such a process can reveal broader concepts that exist beyond specific theoretical terminology, differences in meanings behind common terms used by theorists, a greater understanding of the theorists’ intent, and discontinuities and gaps within the theoretical literature.  相似文献   

The Contribution of Attentional Control and Working Memory to Reading Comprehension and Decoding     

C. Nikki Arrington  Paulina A. Kulesz  David J. Francis  Jack M. Fletcher  Marcia A. Barnes 《Scientific Studies of Reading》2014,18(5):325-346

Little is known about how specific components of working memory, namely, attentional processes including response inhibition, sustained attention, and cognitive inhibition, are related to reading decoding and comprehension. The current study evaluated the relations of reading comprehension, decoding, working memory, and attentional control in 1,134 adolescent students. Path analyses were used to assess the direct and indirect effects of working memory and aspects of attentional control on reading comprehension and decoding. There were significant direct effects of working memory, sustained attention, and cognitive inhibition on reading comprehension, but not decoding. There was a significant direct effect of working memory and response inhibition on decoding, but not comprehension. These results suggest that different aspects of attentional control are important for decoding versus comprehension.  相似文献   

Literacy in Fiji: Its origins and its development     

Francis Mangubhai 《Interchange》1987,18(1-2):124-135

Literacy was introduced into Fiji by Christian missionaries just over 150 years ago, and for almost 100 years limited literacy practices were fostered by schools run mainly by the churches. With the rise of towns and of a bureaucracy, literacy in English as a second language was also introduced. But the levels of literacy in both vernacular and the second languages have been generally low, especially in the rural areas. A research project set up to improve literacy in educational contexts is described. Current problems related to literacy and future developments are discussed.  相似文献
