Innovation and competition take place increasingly between Business Models (BM), and not just among products, processes, and technologies. Therefore, Business Model Innovation (BMI) becomes the key process to unleash value creation for both established and new companies, and, among these latter, particularly for technological spin-offs. For their constituent characteristics, it emerges that BMI in technological spin-offs appears to be related to the effective management of the Intellectual Capital (IC). Despite this, current research has paid little attention to decline BMI through the lenses of IC. This study aims to provide a contribution in this direction by investigating how technological spin-offs innovate their BM by leveraging their IC dimensions. A review of relevant literature on BMI has been carried out. Then, a case study methodology has been adopted to analyze seven technological spin-offs. The analysis highlighted three main trajectories of BMI, defined in terms of the BMI scope and the main exploited IC dimension. The discussion of findings from a research and practical perspective contributes to the debate on BMI, by providing a new interpretative key based on the relevance of the IC dimensions. 相似文献

SYNOPSISInfants’ crying modulates parental behaviors, which in turn, ideally, lead to calming the infant. The mutually beneficial reciprocity between infants’ and parents’ behaviors is conserved across mammalian species. Although some studies highlight similarities in responses to infant cries across gender, other studies report differences in their behaviors and brain activity. Zeifman and colleagues in this Special Issue found that high levels of infant crying can trigger increases in testosterone in men, which is accompanied by less sensitive caregiving. Some interpret males’ lack of sensitive caregiving as neglectful, but these results could be considered as evolutionarily adaptive. Specifically, increases in testosterone levels from intense infant cries could lead to increased vigilance and alertness toward external stimuli, and thus allow males to be better equipped to protect their young. 相似文献

This study employs the Specificity Principle to examine the relative impacts of external (input quantity at home and at school, number of books and reading frequency at home, teachers’ degree and experience, language usage, socioeconomic status) and internal factors (children’s working memory, nonverbal intelligence, learning-related social-skills, chronological age, gender) on children’s English-language development in phonological awareness (PA), receptive vocabulary (RV), and word reading (WR). Altogether, 736 four- to five-year-old Singaporean Mandarin-English speaking kindergarteners were assessed twice longitudinally. Their English-language PA, RV, and WR development was predicted using the eight external factors and five internal factors with Bayesian least absolute shrinkage and selection operators. Internal factors explained more variance than external factors in all three language domains. External factors had their largest impact on RV. 相似文献

This study investigated the relationships between aerobic characteristics and (i) neuromuscular fatigue induced by 2-min sustained isometric maximal voluntary contractions (MVC) and (ii) subsequent recovery, in the upper and lower limbs. In a pseudo-randomized order, eleven healthy males completed four sessions on different days: maximal incremental cycling test (100 W + 40 W every 2 min); maximal arm-cranking test (50 W + 20 W every 2 min); and 2-min sustained isometric MVCs of the knee extensors (KE) and elbow flexors (EF). Neuromuscular assessment was performed with transcranial magnetic and peripheral nerve stimulation to evaluate central and peripheral neuromuscular factors of fatigue and the subsequent recovery. Peak oxygen uptake, gas exchange threshold and the corresponding power outputs were correlated with recovery of voluntary force after the 2-min KE MVC. Regression analysis showed that power output at the gas exchange threshold alone explained 72% of the variability in ?recovery of KE voluntary force. No relationships with fatigue or recovery in EF were observed. These results suggest that participants with greater aerobic capacities experience the same amount of fatigue and faster recovery of voluntary force in KE but not EF. The potential reasons behind the relationship in KE but not EF are discussed. 相似文献

Links with science have been argued to improve the (innovation) performance of firms. Yet we still know comparatively little about the project-level characteristics affecting the organization of such links. Our study, based on a sample of 52 projects carried out by a multinational company in the semiconductor industry, reveals that the knowledge attributes of a project help in predicting how the R&D activities will be organized. In particular, basic projects are likely to be developed through formal cooperative agreements with universities. Such projects also tend to be strategically less important. For strategically more important projects, in contrast, and for those where the knowledge to be developed is particularly novel to the firm, the firm is more likely to resort to formal contracting with a university for a specific component of the R&D project, usually early on in the project. 相似文献

The information sector is a dynamic disciplinary and professional field, located in a fluid social and technological environment. The educational choices of students in library and information science (LIS) departments is an important aspect of the process through which they construct their ambitions, plans, and future capabilities, and so research on students' choices and their educational careers as social processes is also important. Through a detailed consideration of case study accounts of students from LIS departments in Greece, the argument for the importance of social and cultural factors in the formation of students' identity is advanced. Data were collected in two research phases using a questionnaire survey and semi-structured interviews. Analysis of data demonstrates the complexity of the process of making educational choices, revealing how individual, family, social, and institutional factors interrelate with the ways young people cope with contingencies, and with social and personal relations. How these complex influences facilitate or impede students' trajectories within higher education institutions is also shown, as well as how they act upon the construction of their pedagogic identities. Of considerable significance is the finding that students from lower social class backgrounds tend to form pedagogic identities that are fragile. By contrast, students from families with significant amounts of cultural and social capital are in a position to exploit the academic and social resources of institutions, and to construct embedded identities with a strong scientific basis. More research is needed to illuminate how LIS departments could develop mechanisms to reduce such discrepancies. 相似文献

Out of the staters collection of the National Archaeological Museum of Taranto, during the full examination of about one hundred coins minted by the Greek colony of Taras between the V century BC and the III century BC, our attention has been devoted to a lead coin, which has been regarded for many years as a genuine silver coin. This artifact, entry number 13 in the inventory list for the Parabita hoard, has been studied with the combined use of surface and micro-analytical techniques (SEM, EDX, PIXE, XRD). The joint use of different analytical techniques allowed us to obtain information about the morphology, the structure and the chemical composition of the analysed coin, that revealed a lead core coated with a bi-layer of copper and silver. 相似文献

This paper reports both procedures for the kinematic design and the results of dynamic analyses of three models of sit-ski
in order to evaluate their vibrational comfort. The model described in the US Patent US 6,019,380 has been assumed as a reference
in the following kinematic and dynamic analyses of the new models proposed. The two main features to be considered while designing
a sit-ski are the manoeuvrability and the range of vision of the driver. These two features appear to be important considering
that the sit-ski is generally used by disabled people (e.g. paraplegic). Thus the kinematic design phase should account for
the fulfillment of these requirements. On the basis of these, three new models have been proposed and herein named: Flex,
modified Flex and eight-bar linkage (Smarrini 2003). Once the kinematic synthesis and analysis have been completed the dynamic
performance of each model is investigated. For this purpose two kinds of slope profiles are simulated in order to reproduce
the stresses which may likely occur during a downhill race. In particular the position and the acceleration of the seat have
been monitored during the simulations. This is important in order to test the range of vision and handling requirements. The
seat acceleration is also important to evaluate the vibrational comfort of the sit-ski according to the British standard BS
6841 (Griffin 1990). The dynamic simulation is first executed by means of the multibody dynamics code NumDyn3D, then the vibrational
comfort analysis is performed using in-house developed software (Vita 2001, Valentini and Vita 2003). 相似文献
