Trademarks’ relatedness to product and service innovation: A branding strategy approach     

Meindert Flikkema  Carolina Castaldi  Ard-Pieter de Man  Marcel Seip 《Research Policy》2019,48(6):1340-1353

The use of trademark data in innovation studies is still limited because as yet no guidelines exist to ascertain which trademarks relate to innovation. This paper proposes that a branding strategy approach may help to identify innovation related trademarks. Companies use distinctive branding strategies for innovation and these branding strategies have important consequences for the design of new trademarks and their application scope. Based on a sample of Benelux and Community trademarks, we find that trademarks for brand creation relate more often to product innovation. In addition, we find negative effects of a trademark’s industry scope on its relatedness to product innovation, and of a trademark’s geographic scope on its relatedness to service innovation. Our findings bear several key implications for further research towards identifying innovation-related trademarks from a branding strategy perspective.  相似文献   

Changes in the relation between cognitive and metacognitive skills during the acquisition of expertise   总被引：2，自引：0，他引：2

This paper focuses on the transformation of general metacognitive skills of novices into domain-specific regulatory procedures of experts, and the relation of those skills to intelligence. Research has shown that the general metacognitive skills of novices, although partly correlated to intelligence, additionally contribute to learning outcome on top of intelligence. The metacognitive skills of experts appear to be domainspecific and unrelated to intelligence. Two experiments were conducted. The objective of the first experiment was to confirm and generalize these earlier results concerning the relation of intellectual ability, metacognitive skillfulness and learning of novices vs. advanced subjects. The objective of the second experiment was to investigate this relation under different conditions of task complexity. It was hypothesized that advanced subjects would regress to more novice-like behavior under very complex learning conditions (i.e., general metacognitive skills and intelligence would re-appear as combined predictors of learning outcome). On the other hand, low intelligent novices, irrespective of their metacognitive skillfulnes, were expected to fail on very complex problems. Results partly confirmed these hypotheses. Implications for the conditions under which metacognitive experiences should be implemented, are being discussed.  相似文献   

Personalization of tagging systems

Social media systems have encouraged end user participation in the Internet, for the purpose of storing and distributing Internet content, sharing opinions and maintaining relationships. Collaborative tagging allows users to annotate the resulting user-generated content, and enables effective retrieval of otherwise uncategorised data. However, compared to professional web content production, collaborative tagging systems face the challenge that end-users assign tags in an uncontrolled manner, resulting in unsystematic and inconsistent metadata.This paper introduces a framework for the personalization of social media systems. We pinpoint three tasks that would benefit from personalization: collaborative tagging, collaborative browsing and collaborative search. We propose a ranking model for each task that integrates the individual user’s tagging history in the recommendation of tags and content, to align its suggestions to the individual user preferences. We demonstrate on two real data sets that for all three tasks, the personalized ranking should take into account both the user’s own preference and the opinion of others.  相似文献   

Evaluation and management of leukolysis-mediated pseudohyperkalemia in paediatric leukemic samples     

Lourens Jan Peter Nonkes  Valrie de Haas  Hans Kemperman  Albert Huisman  Ruben Eduardus Antonius Musson  Wouter Marcel Tiel Groenestege 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2022,32(1)

IntroductionLeukolysis-related pseudohyperkalemia due to preanalytical procedures may lead to erroneous (or absence of) treatment based on an invalid lab test result. We aimed to obtain a leukocyte threshold above which leukolysis-related pseudohyperkalemia becomes clinical relevant. Secondly, temporal dynamics of treatment-induced leukocyte decrease were studied to allow tailored implementation of laboratory information system (LIS) decision rules based on the leukocyte threshold to avoid leukolysis-related pseudohyperkalemia.Materials and methodsPotassium results of AU5811 routine chemistry (Beckman Coulter, Brea, California, USA) and iStat point of care (POC) (Abbott Diagnostics, Chicago, Illinois, USA) analysers were compared, the latter method being insensitive to leukolysis caused by pre-analytical procedures. Potassium results were combined with leukocyte counts obtained using a Cell-Dyn Sapphire haematology analyser (Abbott Diagnostics, Santa Clara, California, USA), resulting in 132 unique data triplets. Regression analysis was performed to establish a leukocyte threshold. The Reference Change Value (√2 x Z x √(CV_a² + CV_i²)) was used to calculate maximum allowable difference between routine analyser and POC potassium results (delta_max + 0.58 mmol/L). Temporal analysis on the treatment-induced leukocyte decrease was performed by plotting leukocyte counts in time for all patients above the threshold leukocyte count (N = 41).ResultsEstablished leukocyte threshold was 63 x10⁹/L. Temporal analysis showed leukocyte counts below the threshold within 8 days of treatment for all patients.ConclusionsBased on performed analyses we were able to implement LIS decision rules to reduce pseudohyperkalemia due to preanalytical procedures. This implementation can contribute to a reduction in erroneous (or absence of) treatments in the clinic.  相似文献

Analysis of cognitive abilities for learning disabled children     

Hubert Booney Vance  Patricia Gaynor  Margaret Coleman 《Psychology in the schools》1976,13(4):477-483

The study investigated WISC-R subtest pattern scores of 58 learning disabled children (42 boys and 16 girls) ranging in age from 6 years to 15 years, 10 months. The variation in subtest scores was analyzed by a 1 X 10 analysis of variance with repeated measures on the single factor. Differences between individual subtest means were analyzed by the Newman-Keuls test for simple effects. The evidence indicates that the low subtest scores on Arithmetic, Coding and Information were characteristic of this group. The study did not support the verbal-Performance discrepancies as useful in the diagnosis of learning disabilities.  相似文献   

Maturity status effects on torque and muscle architecture of young soccer players

ABSTRACT

This study investigated the effects of maturity status on knee extensor torque and vastus lateralis architecture of young soccer players. Thirty-four males aged 13–18 years were divided into two groups: pubescent (PUB, n = 15) and postpubescent (POSP, n = 19). Torque by angle interaction was established for absolute [F(2.649, 84.771) = 9.066, p < 0.05] and relative to body mass [F(2.704, 86.533) = 4.050, p < 0.05] isometric torque with the POSP group showing greater values. Muscle volume torque-angle relationship was similar between groups. Absolute, relative to body mass, and relative to muscle volume concentric and eccentric torque-velocity relationship showed a non-significant interaction but a significant group effect in favour the POSP group for absolute and concentric torque relative to body mass. Torque-angle and torque-velocity relationship normalized by body mass allometric exponents showed a non-significant interactions and group effects. Muscle thickness (3.6 ± 0.6 vs. 3.8 ± 0.6 cm), fascicle length (8.3 ± 1.4 vs. 8.9 ± 1.6 cm) and pennation angle (15.0 ± 2.3 vs. 14.3 ± 3.2 degrees) was similar between PUB and POSP groups, respectively. Maturity status did not show a significant effect on muscle architecture and on isometric and dynamic torques when allometrically normalized.  相似文献   

TournaRank: When retrieval becomes document competition     

Gilles Hubert  Yoann Pitarch  Karen Pinel-Sauvagnat  Ronan Tournier  Léa Laporte 《Information processing & management》2018,54(2):252-272

Numerous feature-based models have been recently proposed by the information retrieval community. The capability of features to express different relevance facets (query- or document-dependent) can explain such a success story. Such models are most of the time supervised, thus requiring a learning phase. To leverage the advantages of feature-based representations of documents, we propose TournaRank, an unsupervised approach inspired by real-life game and sport competition principles. Documents compete against each other in tournaments using features as evidences of relevance. Tournaments are modeled as a sequence of matches, which involve pairs of documents playing in turn their features. Once a tournament is ended, documents are ranked according to their number of won matches during the tournament. This principle is generic since it can be applied to any collection type. It also provides great flexibility since different alternatives can be considered by changing the tournament type, the match rules, the feature set, or the strategies adopted by documents during matches. TournaRank was experimented on several collections to evaluate our model in different contexts and to compare it with related approaches such as Learning To Rank and fusion ones: the TREC Robust2004 collection for homogeneous documents, the TREC Web2014 (ClueWeb12) collection for heterogeneous web documents, and the LETOR3.0 collection for comparison with supervised feature-based models.  相似文献   

Innovation and Entrepreneurship: Journalism Students’ Interpretive Repertoires for a Changing Occupation     

Jane B. Singer  Marcel Broersma 《Journalism Practice》2020,14(3):319-338

ABSTRACT

Amid ongoing disruption, discourse about journalism increasingly emphasizes innovation within the newsroom and the rise of entrepreneurial initiatives outside it. This article uses the concept of interpretive repertoires to explore how students enrolled in journalism programmes in Britain and the Netherlands understand innovation and entrepreneurialism in relation to changing industry circumstances and long-standing conceptualizations of occupational norms and behaviours. We find shared repertoires that embrace technological change, but generally within an acceptance of traditional normative practice.  相似文献   

Having students create short video clips to help transition from naïve conceptions about mechanics to true Newtonian physics     

Pascale Corten-Gualtieri  Christian Ritter  Jim Plumat  Roland Keunings  Marcel Lebrun 《European Journal of Engineering Education》2016,41(4):438-454

Most students enter their first university physics course with a system of beliefs and intuitions which are often inconsistent with the Newtonian frame of reference. This article presents an experiment of collaborative learning aiming at helping first-year students in an engineering programme to transition from their naïve intuition about dynamics to the Newtonian way of thinking. In a first activity, students were asked to critically analyse the contents of two video clips from the point of view of Newtonian mechanics. In a second activity, students had to design and realise their own video clip to illustrate a given aspect of Newtonian mechanics. The preparation of the scenario for the second activity required looking up and assimilating scientific knowledge. The efficiency of the activity was assessed on an enhanced version of the statistical analysis method proposed by Hestenes and Halloun, which relies on a pre-test and a post-test to measure individual learning.  相似文献
