A neo-Schumpeterian model of health services innovation     

Paul Windrum  Manuel García-Goñi 《Research Policy》2008,37(4):649-672

The paper presents and empirically applies a neo-Schumpeterian model of innovation capable of studying interactions between service providers, patients and policy makers, and how these complex interactions determine the timing, direction, and success of innovations in the public sector. The model is tested using a case study that traces the introduction and development of ambulatory surgery in a Spanish hospital. The multi-agent model applies the ideas of Schumpeter to services, encompassing Schumpeter's five types of innovation, and re-introducing the policy-maker as a key agent in the innovation process. The model has a number of advantages over previous, reduced form models. First, it can analyse the interactions between the economic, social and political spheres that make up the complex selection environment of innovations. Second, it captures the recursive impact of radical innovations on agents’ competences and preferences, and their relative power. This brings politics, power, and rhetorical persuasion to the fore. Third, it provides an improved set of definitions for radical and incremental innovation. These are not only important for understanding the sources and drivers of innovation, but also for the accurate measurement of innovation.  相似文献   

Analysis of foot strike pattern,rearfoot dynamic and foot rotation over childhood. A cross-sectional study     

Pedro Ángel Latorre Román  Fernando Redondo Balboa  Juan Párraga Montilla  Víctor Manuel Soto Hermoso  Pedro José Consuegra González  Felipe García Pinillos 《Journal of sports sciences》2019,37(5):477-483

The purpose of this study was to determine the foot strike patterns (FSP), rearfoot position at initial contact (RPic, i.e., No INV/EVE) and foot rotation in children in relation to age. A total of 932 children aged 3 to 16 years participated in this study. A sagittal and frontal-plane video was recorded using a high-speed camcorder to analyse these variables. There is a significant increase (p < 0.001) of rearfoot strike patterns (RFS) prevalence in relation to age; e.g. preschool children (3–6 years old) displayed an RFS prevalence 46.65% and the adolescent population(15–16 years old) an RFS prevalence 92.20%. The total RFS prevalence in all samples was 69.25%. There was a significant reduction (p < 0.001) of prevalence of RPic in relation to age groups; preschool children displayed a prevalence of RPic 60.37% and the adolescent population 10%. There was a significant reduction (p < 0.001) of prevalence of no foot rotation in relation to age groups; preschool children displayed a prevalence of no foot rotation 48.95% and the adolescent population 13.55%. In conclusion, FSP in children are influenced by age. It is noteworthy that the RFS prevalence of children is lower in comparison to the adult population.  相似文献   

“Let’s make lots of money”: the determinants of performance in the recorded music sector     

Juan D. Montoro-Pons  Manuel Cuadrado-García 《Journal of Cultural Economics》2018,42(2):287-307

This research analyzes the performance of 467 record labels in eight European countries over a period of 13 years (2003–2015). The main goal is to explain a relative measure of profitability in terms of observed variables, although the nature of the dataset also allows us to include non-observed firm and country effects. To this end alternative models are estimated and three main research questions are tested, namely: (1) the effect of the dual structure of the recorded music market, in which a competitive segment and an oligopoly coexist; (2) the extent and source of the volatility of profits in record labels; and (3) the nonlinear impact of size on performance.  相似文献

Creative adaptation: the role of new technology based firms in Portugal     

Manuel Laranja  Margarida Fontes 《Research Policy》1998,26(9):1023-1036

This paper reviews two recent research studies on Portuguese New Technology Based Firms (NTBFs). Attention is given to the role and contribution of NTBFs to innovation. The main argument is that, by and large, NTBFs are less concerned with the introduction of major innovations and more with creative adaptive improvements to products and services based upon new technologies first introduced elsewhere. The empirical research found that Portuguese NTBFs are a recent phenomenon associated with diffusion of Electronics and Information Technologies (EIT) during the late 1980s. They perform a wide variety of knowledge-intensive activities, which enhance local users' adoption processes and they are associated with different forms of technology transfer through external linkages. Overall, NTBFs undertake a frequently unobserved role as technology searchers and acquirers that, pushed by idiosyncratic local niche market opportunities, selectively choose among and enhance technologies developed elsewhere, introducing them into the local market.  相似文献   

The effects of self-efficacy,hope, and engagement on the academic achievement of secondary education in the Dominican Republic     

José Manuel Tomás  Melchor Gutiérrez  Sylvia Georgieva  Miosotis Hernández 《Psychology in the schools》2020,57(2):191-203

Achievement in the academic settings has long lasting positive outcomes. In this study, hope, self-efficacy, and engagement are linked to academic success. The aims of this study were to test a model which predicts academic success in the Dominican Republic while testing for the mediator role of engagement. The sample was composed of 614 middle-school students. Scales of Dispositional Hope, Academic Self-Efficacy, Academic Self-concept, and Engagement were used. Academic performance was measured with students' grades in Spanish and Mathematics. Three structural equation models were tested. The retained model stated hope and self-efficacy as antecedents, engagement dimensions as mediators and grades and academic self-concept as final outcomes. There were significant effects of hope and self-efficacy on engagement, and behavioral engagement was the best predictor of academic success. These results point out that interventions should target variables, such as hope or engagement to increase academic success.  相似文献   

Microclimate monitoring by multivariate statistical control: The renaissance frescoes of the Cathedral of Valencia (Spain)     

Fernando-Juan García-Diego  Manuel Zarzo 《Journal of Cultural Heritage》2010,11(3):339-344

The renaissance frescoes of the metropolitan cathedral of Valencia, located at the vault of the apse, were restored in 2006. We describe a microclimate monitoring system that was implemented for the preventive conservation of the paintings. It is comprised by a set of temperature and relative humidity sensors positioned at different points of the vault. This system is rather unique because some of these sensors were inserted inside the paintings during the restoration process. A principal components analysis was applied to the data of relative humidity recorded in February 2007. The analysis was repeated in three additional months of 2007. The resulting loading plots highlight the most relevant similarities and dissimilarities among sensors. These plots can be considered as some sort of control maps that could be used to detect abnormal conditions in the future. Actually, moisture problems at certain zones of the frescoes are causing the formation of efflorescence, and the sensors located close to these zones are the ones recording the highest values of relative humidity.  相似文献
