Networks of inventors and the role of academia: an exploration of Italian patent data   总被引：3，自引：0，他引：3

This paper proposes a quantitative analysis of social distance between Open Science and Proprietary Technology. A few general properties of social networks within both realms are discussed, as they emerge from the new economics of science and recent applied work on “small worlds”. A new data-set on patent inventors is explored, in order to show that social networks within Proprietary Technology are much more fragmented than Open Science ones, except for science-based technologies. Two propositions are then put forward on the “open” behaviour expected from academic inventors, namely university scientists getting involved in Proprietary Technology networks by signing patents. Both propositions are confirmed by data, which show academic inventors to be more central and better connected than non-academic ones. The database and methodology produced for this paper are suggested to be relevant for the more general debate on the role of geographical and cognitive distance in university-industry technology transfer.  相似文献   

Making Sense of Number Words and Arabic Digits: Does Order Count More?     

Francesco Sella  Daniela Lucangeli  Roi Cohen Kadosh  Marco Zorzi 《Child development》2020,91(5):1456-1470

The ability to choose the larger between two numbers reflects a mature understanding of the magnitude associated with numerical symbols. The present study explores how the knowledge of the number sequence and memory capacity (verbal and visuospatial) relate to number comparison skills while controlling for cardinal knowledge. Preschool children’s (N = 140, M_{age-in-months} = 58.9, range = 41–75) knowledge of the directional property of the counting list as well as the spatial mapping of digits on the visual line were assessed. The ability to order digits on the visual line mediated the relation between memory capacity and number comparison skills while controlling for cardinal knowledge. Beyond cardinality, the knowledge of the (spatial) order of numbers marks the understanding of the magnitude associated with numbers.  相似文献   

Academic inventors as brokers   总被引：4，自引：0，他引：4  

Francesco Lissoni 《Research Policy》2010,39(7):843-857

Academic inventors are university scientists who appear as designated inventors of patents owned either by business companies, academic institutions or individuals. We analyse their relationships with co-inventors, who may be either academic colleagues, students, or, very often, industrial researchers. Gould and Fernandez's (1989) taxonomy of ‘brokerage’ roles is adjusted to patent data, and complemented with information drawn from both academic inventors’ publications and replies to a short questionnaire. Only very few academic inventors are found to hold brokerage positions. Such inventors have a large number of patents, a strong publication record and a higher-than-average share of patents held by companies, rather than universities. Relationships of academic inventors with co-inventors from industry are weaker and less likely to be maintained than those with co-inventors from academia. Academic inventors in gatekeeping positions (between university and industry) maintain the strongest ties with all types of co-inventors.  相似文献   

Interindividual Differences in Neonatal Imitation and the Development of Action Chains in Rhesus Macaques   总被引：1，自引：0，他引：1

The capacity to imitate facial gestures is highly variable in rhesus macaques and this variability may be related to differences in specific neurobehavioral patterns of development. This study evaluated the differential neonatal imitative response of 41 macaques in relation to the development of sensory, motor, and cognitive skills throughout the 1st month of life. The results show that infants who imitate facial gestures display more developed skills in goal-directed movements (reaching–grasping and fine hand motor control) than nonimitators. These differences might reflect, at least in part, the differential maturation of motor chains in the parietal and motor cortices, which partly overlap with those of the mirror neuron system. Thus, neonatal imitation appears to be a predictor of future neurobehavioral development.  相似文献   

‘Connected to Something’: Soccer and the Transnational Passions,Memories and Communities of Sydney's Italian Migrants     

Francesco Ricatti 《国际体育史杂志》2013,30(5):469-483

This paper explores the importance soccer can play in the lives, identities and memories of migrants by drawing on 32 oral history interviews conducted with Italians who settled in Sydney in the 1950s and 1960s. Sport can provide an illuminating lens for analysing the experience of migrants, because not only are sports sites of individual, regional, national and transnational identities, they can also facilitate social inclusion or, conversely, become sites of exclusion. Soccer in Australia is often celebrated as a multicultural game. At the same time, the expressions of the complex histories of migration, colonialism, exploitation and racial and ethnic discrimination that have shaped the game have often been silenced. The interviews show that soccer has been a key site of negotiation, agency and at times resistance for first and second generation migrants. We also argue that, while it is the de-ethnicisation of soccer that has understandably dominated media, political and academic debate, the concern of these migrants in recent years has been mostly with the loss of memory and with the removal of an important history made of shared relationships and bonding experiences.  相似文献   

Physiological and biomechanical responses to walking underwater on a non-motorised treadmill: effects of different exercise intensities and depths in middle-aged healthy women

Abstract

Non-motorised underwater treadmills are commonly used in fitness activities. However, no studies have examined physiological and biomechanical responses of walking on non-motorised treadmills at different intensities and depths. Fifteen middle-aged healthy women underwent two underwater walking tests at two different depths, immersed either up to the xiphoid process (deep water) or the iliac crest (shallow water), at 100, 110, 120, 130 step-per-minute (spm). Oxygen consumption (VO₂), heart rate (HR), blood lactate concentration, perceived exertion and step length were determined. Compared to deep water, walking in shallow water exhibited, at all intensities, significantly higher VO₂ (+13.5%, on average) and HR (+8.1%, on average) responses. Water depth did not influence lactate concentration, whereas perceived exertion was higher in shallow compared to deep water, solely at 120 (+40%) and 130 (+39.4%) spm. Average step length was reduced as the intensity increased (from 100 to 130 spm), irrespective of water depth. Expressed as a percentage of maximum, average VO₂ and HR were: 64–76% of peak VO₂ and 71–90% of maximum HR, respectively at both water depths. Accordingly, this form of exercise can be included in the “vigorous” range of exercise intensity, at any of the step frequencies used in this study.  相似文献

Changes in Sensory Dominance During Childhood: Converging Evidence From the Colavita Effect and the Sound‐Induced Flash Illusion     

Elena Nava  Francesco Pavani 《Child development》2013,84(2):604-616

In human adults, visual dominance emerges in several multisensory tasks. In children, auditory dominance has been reported up to 4 years of age. To establish when sensory dominance changes during development, 41 children (6–7, 9–10, and 11–12 years) were tested on the Colavita task (Experiment 1) and 32 children (6–7, 9–10, and 11–12 years) were tested on the sound‐induced flash illusion (Experiment 2). In both experiments, an auditory dominance emerged in 6‐ to 7‐year‐old children compared to older children. Adult‐like visual dominance started to emerge from 9 to 10 years of age, and consolidated in 11‐ to 12‐year‐old children. These findings show that auditory dominance persists up to 6 years, but switches to visual dominance during the first school years.  相似文献
