The impact of M&A on the R&D process: An empirical analysis of the role of technological- and market-relatedness     

Bruno Cassiman  Massimo G. Colombo  Reinhilde Veugelers 《Research Policy》2005,34(2):195-220

Using information on 31 in-depth cases of individual M&A deals, we show that technological and market-relatedness between M&A partners distinctly affects the inputs, outputs, performance and organisational structure of the R&D process. While the findings in the literature on the effect of M&A on R&D are quite mixed, we can sharpen results by analysing data at the level of the R&D process. This comes at the price of a smaller sample and more qualitative data, for which caution in the interpretation is necessary. M&A between partners with ex-ante complementary technologies result in more active R&D performers after the M&A. In sharp contrast, when merged entities are technologically substitutive, they significantly decrease their R&D level after the M&A. Moreover, R&D efficiency increases more prominently when merged entities are technologically complementary than when they are substitutive. These two findings on the R&D level and the performance support the scope economy effect of M&A, on the one hand, and reject the scale economy effect of M&A, on the other. Next, for cases in which partners were active in the same technological fields before the M&A, the reduction of R&D is more prominent, while the R&D efficiency gain is smaller if merged entities were rivals in the product market prior to their merger than if they were non-rival. This suggests that rival firms reap little technology gains from mergers.  相似文献

Self-selected or imposed exercise? A different approach for affective comparisons     

Bruno Ribeiro Ramalho Oliveira  Andréa Camaz Deslandes  Fábio Yuzo Nakamura  Bruno Ferreira Viana 《Journal of sports sciences》2015,33(8):777-785

The aim of this study was to compare the psychological and physiological responses of self-selected and imposed sessions of equivalent intensities and durations and allowing to participants a free control of pace during the self-selected session. Seventeen participants completed three sessions on a cycle ergometer. Participant’s VO_2Peak and lactate threshold were measured during an incremental exercise test. During the second and third sessions, participants could view a virtual cyclist on a monitor. During the self-selected session, participants were allowed free control of the intensity and duration. To ensure that the imposed session replicated the self-selected session in intensity, participants were instructed to follow an additional virtual cyclist, which was displayed on a monitor using the CompuTrainer 3D software. Power output and physiological and psychological variables were recorded during the sessions. A two-way ANOVA showed no effect of condition for power output (P = 0.940), heart rate (HR) (P = 0.965), VO₂ (P = 0.898), blood lactate (P = 0.667), Feeling Scale (P = 0.877), Felt Arousal Scale (P = 0.924) and CR100 (P = 0.939). A paired t-test showed no significant difference in Physical Activity Enjoyment Scale scores between sessions (P = 0.054). In contrast to previous studies, the self-selected session did not provide better affective responses than the imposed session with same intensity and duration.  相似文献

Conservation strategy for food-based perishable art: preservation versus reconstruction illustrated by Piece in Ghent by Jason Rhoades (1994)     

Julie Gilman  Liesbeth Jacxens  Bruno Demeulenaer 《文物保护研究》2016,61(1):3-12

The aim of this paper was to discuss the role of food preservation science and technology in the conservation of complex food-based installations. By introducing the principles of food science and food preservation into the decision-making process for the conservation of contemporary art, more insight on conservation and presentation possibilities was created. Considering the installation Piece in Ghent (P.I.G.) by Jason Rhoades, which contains French fries, the principles of food preservation science were evaluated. The preservation of the original foods was discussed against the potential of a reproduction of the foods. The context for conservation was determined by analysing the artist's intention, the production method of the artwork, and the degradation processes of the food materials. From the results obtained, guidelines to preserve the ‘original’ foods were proposed, as well as guidelines to reproduce foods that can last longer. The study demonstrated that food preservation science contributed to the development of effective strategies for the conservation of contemporary food-based art.  相似文献   

Space occupation near the basket shapes collective behaviours in youth basketball     

Pedro T. Esteves  Pedro Silva  Luís Vilar  Bruno Travassos  Ricardo Duarte  Jorge Arede 《Journal of sports sciences》2016,34(16):1557-1563

This study aimed to analyse how youth basketball players explored numerical overloads during shot attempts by measuring their space occupation across specific court areas. Four process-tracing variables measured how the number of attackers (NA), number of defenders (ND), interpersonal distance between attacker and the closest defender (ID) and distance between attacker and the basket (DBkt) impacted on the performance outcome (converted shot; missed shot; ball possession lost). Ten competitive games involving 13 U14 teams were video recorded and players’ displacements were digitised. The associations between performance outcomes and the process-tracing measures were assessed using standardised mean differences and a cross-correlation function. A multinomial logistic regression was used to calculate the odds ratio (OR) for each of the three possible outcomes. Results revealed that when shot attempts occurred at larger ID and at smaller DBkt, the possibilities to obtain a converted shot increased. The numerical overload of defenders near the scoring target was predominantly associated with offensive success. Also, the possibility of attackers to lead the spatial relation of movements with the defenders, near the scoring target, appeared as a prominent strategy to succeed. In sum, basketball teams that exhibit potential to adapt their collective behaviours to local changes in the environment might be closer to achieving successful outcomes.  相似文献   

Does the EDI Measure School Readiness in the Same Way Across Different Groups of Children?     

Martin Guhn  Anne Gadermann  Bruno D. Zumbo 《Early education and development》2007,18(3):453-472

The present study investigates whether the Early Development Instrument (Offord & Janus, 1999) measures school readiness similarly across different groups of children. We employ ordinal logistic regression to investigate differential item functioning, a method of examining measurement bias. For 40,000 children, our analysis compares groups according to gender, English-as-a-second-language (ESL) status, and Aboriginal status. Our results indicate no systematic measurement differences regarding Aboriginal status and gender, except for 1 item on which boys are more likely than girls to be rated as physically aggressive by Kindergarten teachers. In contrast, ESL children systematically receive lower ratings on items of the language and communication domains—as expected by definition of ESL status—but not within the physical, social, and emotional domains. We discuss how our results fit with child development research and the purpose of the Early Development Instrument, thus supporting its validity.  相似文献
