This paper presents a conceptual model to explore the knowledge integration (KI) practices of internal and external company actors involved in the New Product Development (NPD) process of the aerospace industry. The model is based on the linkage of elasticity principles, particularly Hooke’s Law, to Knowledge Management theory. KI practices are considered as a force pushing the NPD process and are metaphorically described as the spring addressed by Hooke’s law. The integration of the knowledge of internal and external company actors impacts NPD, reducing the dimensions of the whole process, in terms of phases, through the application of the concurrent engineering approach. The whole NPD process is improved in terms of the reduction of uncertainty and complexity, and with an ‘integrated energy’ that sustains the pressure of the fast-changing competitive environment. The model is explored to provide an interpretation of the conceptualisation phase of a new aerospace product development process. Qualitative data were collected and analysed. Insights regarding the applications of the model and the theoretical implications are also provided for applications in other industries.  相似文献   

Pigeons exhibit higher accuracy for chosen memory tests than for forced memory tests in duration matching-to-sample     

Adams A  Santi A 《Learning & behavior》2011,39(1):1-11

Following training to match 2- and 8-sec durations of feederlight to red and green comparisons with a 0-sec baseline delay, pigeons were allowed to choose to take a memory test or to escape the memory test. The effects of sample omission, increases in retention interval, and variation in trial spacing on selection of the escape option and accuracy were studied. During initial testing, escaping the test did not increase as the task became more difficult, and there was no difference in accuracy between chosen and forced memory tests. However, with extended training, accuracy for chosen tests was significantly greater than for forced tests. In addition, two pigeons exhibited higher accuracy on chosen tests than on forced tests at the short retention interval and greater escape rates at the long retention interval. These results have not been obtained in previous studies with pigeons when the choice to take the test or to escape the test is given before test stimuli are presented. It appears that task-specific methodological factors may determine whether a particular species will exhibit the two behavioral effects that were initially proposed as potentially indicative of metacognition.  相似文献   

Differential outcome expectancies and directed forgetting effects in pigeons     

Angelo Santi 《Learning & behavior》1989,17(3):349-354

Pigeons were trained in a two-choice delayed matching-to-sample task with red and green hues. A brief postsample cue (a vertical or horizontal line) signaled whether the comparison stimuli would be presented or omitted on each trial. Comparison stimuli were always presented following the remember (R) cue, but never following the forget (F) cue or no-cue trials. One group of birds, the differential outcome (DO) group, received reinforcement with a probability of 1.0 for correct responses following one sample stimulus and a probability of 0.2 for correct responses following the other sample stimulus. The nondifferential outcome (NDO) group received reinforcement with a probability of 0.6 for correct responses to either stimulus. The effect of postsample cues was greater for the DO group than for the NDO group. Relative to the NDO group, the DO group displayed higher accuracy on R-cue trials and lower accuracy on F- and no-cue trials. Both tendencies contributed to the enhanced cue effectiveness obtained in the DO group. The results indicate that outcome expectancies are subject to maintenance rehearsal, which comes under the control of postsample R and F cues. They also suggest that maintenance rehearsal may be easier to sustain under DO conditions than under NDO conditions when a memory test is anticipated, but that it may be easier to terminate maintenance rehearsal under DO conditions when a memory test is not anticipated. The results are inconsistent with the assumption that the rehearsal of outcome expectancies is automatic.  相似文献   

Transcribing and Digitizing Eighteenth- and Nineteenth-Century Letters for a Historical Digital Repository     

Emily S. Dunster  F. Michael Angelo 《Medical reference services quarterly》2013,32(3):278-282

In fall 2011, the Scott Memorial Library purchased 53 letters belonging to an 1841 graduate of Jefferson Medical College, John Plimpton Green. The library staff transcribed and digitized the letters, creating an online collection in the university's institutional repository, Jefferson Digital Commons. This article will detail the process of transcribing and digitizing the collection along with sharing statistics and the benefits of this project to global researchers.  相似文献   

Gender differences in research collaboration     

Giovanni Abramo  Ciriaco Andrea D’Angelo  Gianluca Murgia 《Journal of Informetrics》2013,7(4):811-822

The debate on the role of women in the academic world has focused on various phenomena that could be at the root of the gender gap seen in many nations. However, in spite of the ever more collaborative character of scientific research, the issue of gender aspects in research collaborations has been treated in a marginal manner. In this article we apply an innovative bibliometric approach based on the propensity for collaboration by individual academics, which permits measurement of gender differences in the propensity to collaborate by fields, disciplines and forms of collaboration: intramural, extramural domestic and international. The analysis of the scientific production of Italian academics shows that women researchers register a greater capacity to collaborate in all the forms analyzed, with the exception of international collaboration, where there is still a gap in comparison to male colleagues.  相似文献   

The collaboration behaviors of scientists in Italy: A field level analysis     

Giovanni Abramo  Ciriaco Andrea D’Angelo  Gianluca Murgia 《Journal of Informetrics》2013,7(2):442-454

The analysis of research collaboration by field is traditionally conducted beginning with the classification of the publications from the context of interest. In this work we propose an alternative approach based on the classification of the authors by field. The proposed method is more precise if the intended use is to provide a benchmark for the evaluation of individual propensity to collaborate. In the current study we apply the new methodology to all Italian university researchers in the hard sciences, measuring the propensity to collaborate for the various fields: in general, and specifically with intramural colleagues, extramural domestic and extramural foreign organizations. Using a simulation, we show that the results present substantial differences from those obtained through application of traditional approaches.  相似文献   

The importance of accounting for the number of co-authors and their order when assessing research performance at the individual level in the life sciences     

Giovanni Abramo  Ciriaco Andrea D’Angelo  Francesco Rosati 《Journal of Informetrics》2013,7(1):198-208

Accurate measurement of research productivity should take account of both the number of co-authors of every scientific work and of the different contributions of the individuals. For researchers in the life sciences, common practice is to indicate such contributions through position in the authors list. In this work, we measure the distortion introduced to bibliometric ranking lists for scientific productivity when the number of co-authors or their position in the list is ignored. The field of observation consists of all Italian university professors working in the life sciences, with scientific production examined over the period 2004–2008. The outcomes of the study lead to a recommendation against using indicators or evaluation methods that ignore the different authors’ contributions to the research results.  相似文献   

Individual research performance: A proposal for comparing apples to oranges     

Giovanni Abramo  Tindaro Cicero  Ciriaco Andrea D’Angelo 《Journal of Informetrics》2013,7(2):528-539

The evaluation of performance at the individual level is of fundamental importance in informing management decisions. The literature provides various indicators and types of measures, however a problem that is still unresolved and little addressed is how to compare the performance of researchers working in different fields (apples to oranges). In this work we propose a solution, testing various scaling factors for the distributions of research productivity in 174 scientific fields. The analysis is based on the observation of scientific production by all Italian university researchers active in the hard sciences over the period 2004–2008, as indexed by the Web of Science. The most effective scaling factor is the average of the productivity distribution of researchers with productivity above zero.  相似文献   

Rats exhibit asymmetrical retention functions for hedonic and nonhedonic samples in many-to-one symbolic delayed matching to sample     

Angelo Santi  Sabrina Simmons  Shannon Mischler  Claire Hoover 《Learning & behavior》2013,41(2):168-178

Rats were initially trained in a symbolic delayed matching-to-sample task either to discriminate hedonic samples that consisted of food or no food or to discriminate tone samples that differed in frequency and location. The retention functions for both the hedonic and tone samples were asymmetric, with forgetting of the food sample or the high-frequency tone occurring more rapidly than forgetting of the no-food sample or the low-frequency tone. Next, many-to-one (MTO) training was given in which tone samples were added for the rats initially trained with hedonic samples, and hedonic samples were added for the rats initially trained with tone samples. For both groups, a food sample and a tone sample (tone-F) were associated with responding to one lever (e.g., stationary), and a no-food sample and a different tone sample (tone-NF) were associated with responding to the alternative lever (e.g., moving). During retention testing, we found equivalent forgetting for the food and no-food samples, but forgetting of the tone-F sample occurred more rapidly than forgetting of the tone-NF sample. This is the first MTO study to suggest that rats, like pigeons, may use hedonic samples as the basis for the common coding of nonhedonic samples in MTO delayed matching.  相似文献   

Pre-service teachers’ perceptions of middle school students     

Kevin J. O’Connor  Christina M. D’Angelo 《Educational studies》2013,39(5):548-551

This report shares a study that explored the perceptions pre-service teachers have of middle school students. Participants were asked to complete the Adjective Checklist (ACL) by endorsing the words they considered most characteristic of a typical middle school student. Items most frequently endorsed indicated a predominantly negative perception (e.g. “awkward”, “confused” and “emotional”). Implications for pre-service teacher training are discussed.  相似文献
