Accuracy and precision of loadsol® insole force-sensors for the quantification of ground reaction force-based biomechanical running parameters     

Wolfgang Seiberl  Elisabeth Jensen  Josephine Merker  Marco Leitel  Ansgar Schwirtz 《European Journal of Sport Science》2018,18(8):1100-1109

Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for measuring in the field are needed. This work analysed the accuracy and precision of a new wireless insole forcesensor for quantifying running-related kinetic parameters. Vertical ground reaction force (GRF) was simultaneously measured with pit-mounted force plates (1?kHz) and loadsol^® sensors (100?Hz) under unshod forefoot and rearfoot running-step conditions. GRF data collections were repeated four times, each separated by 30 min treadmill running, to test influence of extended use. A repeated-measures ANOVA was used to identify differences between measurement devices. Additionally, mean bias and Bland–Altman limits of agreement (LoA) were calculated. We found a significant difference (p?® devices for these parameters. For these same parameters, the LoA analysis showed that 95% of all measurement differences between insole and force plate measurements were less than 12%, demonstrating high precision of the sensors. However, highly dynamic behaviour of GRF, such as force rate, is not yet sufficiently resolved by the insole devices, which is likely explained by the low sampling rate.  相似文献   

A comparative evaluation of regional subsidies for collaborative and individual R&D in small and medium-sized enterprises     

Annalisa Caloffi  Marco Mariani  Federica Rossi  Margherita Russo 《Research Policy》2018,47(8):1437-1447

We analyse whether public subsidies supporting collaborative research and development (R&D) projects in small and medium-sized enterprises (SMEs) are able to encourage persistent R&D investment and interorganisational networking more than subsidies supporting individual R&D projects. Adopting a counterfactual approach to policy evaluation, we compare subsidies for collaborative R&D and for individual R&D implemented in the same Italian region in the same period. Our findings suggest that, once public support is no longer available, the two subsidies have different effects on different types of SMEs. If the policymakers’ objective is to increase the number of R&D-performing SMEs over time, they should provide subsidies for collaborative R&D to firms with modest R&D experience. If their objective is to increase the amount of spontaneous R&D investment over time, they should target SMEs with some prior R&D experience, using either subsidy. Finally, if their objective is to induce SMEs to network with external organisations, subsidies for collaborative R&D projects should be preferred to subsidies for individual R&D projects.  相似文献   

Technology and employment: Mass unemployment or job creation? Empirical evidence from European patenting firms     

Vincent Van Roy  Dániel Vértesy  Marco Vivarelli 《Research Policy》2018,47(9):1762-1776

This paper explores the possible job creation effect of innovation activity. We analyze a unique panel dataset covering almost 20,000 patenting firms from Europe over the period 2003–2012. The main outcome from the proposed GMM-SYS estimations is the labor-friendly nature of innovation, which we measure in terms of forward-citation weighted patents. However, this positive impact of innovation is statistically significant only for firms in the high-tech manufacturing sectors, while not significant in low-tech manufacturing and services.  相似文献   

Electromechanical delay of the knee flexor muscles after anterior cruciate ligament reconstruction using semitendinosus tendon     

Marco Freddolini  Aluena Battaglioli  Filippo Chiechi  Giacomo Placella  Anastasios Georgoulis  Giuliano Cerulli 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(4):384-393

The purpose of the study was to evaluate whether using only the semitendinosus as a tripled short graft would affect the electromechanical delay (EMD) of the knee flexors. EMD was evaluated in volunteers (N = 15) after they had undergone surgery for anterior cruciate ligament (ACL) reconstruction where the semitendinosus tendon alone was used as a graft. The results were compared with the intact leg and healthy controls (N = 15). After warming up, each subject performed four maximally explosive isometric contractions on an isokinetic dynamometer. Torques were measured by the dynamometer, while the electrical activity of the semitendinosus and biceps femoris muscles was detected using surface electromyography. EMD was found to be significantly increased (p = 0.001) in patients who had undergone ACL reconstruction compared to the controls. On the contrary, no significant differences (p = 0.235) were found for the biceps femoris muscle between the two groups. Similar results were found when the study group was compared with the intact leg group (p = 0.027 for semitendinosus and p = 0.859 for biceps femoris). Harvesting the semitendinosus tendon increases the EMD for the semitendinosus muscle but does not influence the EMD outcomes for the biceps femoris muscle.  相似文献   

Governing through guidance: an analysis of educational guidance practices in an Italian lower secondary school     

Marco Romito 《Discourse: Studies in the Cultural Politics of Education》2019,40(6):773-788

ABSTRACT

Current social policy discourse defines educational and career guidance as a key tool to enhance individual self-realisation while pursuing collective social objectives (economic growth, reduction of drop-out rate, social inclusion). Relying on Foucault’s concept of governmentality, critical research has long destabilised this mainstream narrative by stressing that guidance polices constitute a technology of government through which the political ambition to govern is realised by shaping citizens’ desires and ambitions. This article aims to provide an in-depth empirical analysis of how governing practices unfold within a concrete guidance setting. Based on ethnographic data, the essay focuses on guidance practices addressing 13–14-year-old students in Italy moving from comprehensive education to a tracked educational level. Particular emphasis is given to the role played by guidance forms, questionnaires and exercises. These materials, it is argued, enable particular technologies of the self that are key to involving individual in practices of self-government.  相似文献   

Stairway to employment? Internships in higher education     

Patrícia Silva  Betina Lopes  Marco Costa  Dina Seabra  Ana I. Melo  Elisabeth Brito  Gonçalo Paiva Dias 《Higher Education》2016,72(6):703-721

This article aims to shed light on the current debate regarding the role of internships in higher education in graduates’ employability. In specific, it analyses empirical data on a large-scale study of Portuguese first-cycle study programmes, in order to explore indicators of the professional value of internships in the employability of higher education graduates. Results demonstrate that study programmes that include internships tend to significantly enhance graduates’ employability, particularly within the universe of polytechnic and public higher education institutions. Besides the instrumental value of internships, the impact of the nature and structure of the internship on the percentage of unemployed graduates are also discussed. Mandatory internships and the inclusion of multiple, shorter internships throughout the degree are negatively associated with unemployment levels. Results indicate work-based learning can be used as a successful strategy to bridge theoretical knowledge and practice and enhance graduate employability. These findings provide important insights for the evaluation and/or the design of internship programmes in higher education.  相似文献   

Extended teams in vocational education: collaboration on the border     

Marco Mazereeuw  Iwan Wopereis  Susan McKenney 《Educational Research and Evaluation》2016,22(3-4):194-212

ABSTRACT

Extended Teams (ETs), in which teachers and workplace supervisors are jointly responsible for the quality of education, were established to solve problems concerning school–workplace connections in vocational and professional education. Six ETs were investigated during their 1st year of collaboration. In addition to recordings of ET meetings, questionnaires, focus groups, and interviews yielded triangulation of data pertaining to dimensions of team work and professional growth of individual team members. Five of the 6 teams showed marked changes for team functioning, especially with regard to social ties and intellectual building as well as needs for new knowledge. Analysis of individual professional growth indicated that working in an ET contributed to understanding the other context, and altering views of what can be achieved by and for students. We conclude that ETs hold potential for strengthening school–workplace connections, but note that they did rely heavily on external support.  相似文献   

The Role of Historical-Philosophical Controversies in Teaching Sciences: The Debate Between Biot and Ampère     

Marco Braga  Andreia Guerra  José Claudio Reis 《Science & Education》2012,21(6):921-934

This paper evaluates the viability of using controversies in teaching. An educational project has been elaborated in which some historical-philosophical clashes were introduced into the classical syllabus of physics. The historical-philosophical controversy dealt with here, took place between the French physicists Biot and Ampère in the 19th century and referred to distinct interpretations of the Oersted experiment. This controversy was inserted into the syllabus of the 12th grade of a Brazilian secondary school.  相似文献   

Effective formative e-assessment of student learning: a study on a statistics course     

Paula Hodgson  Marco Y.C. Pang 《Assessment & Evaluation in Higher Education》2012,37(2):215-225

The process of formative assessment in universities has the potential to engage students in reflection and to take greater ownership of their learning. We report on a study involving 104 students taking a statistics course in a degree programme in rehabilitation science in Hong Kong. The assessment strategy was redesigned to include a weekly online formative assessment activity for 10 weeks. In this case, it was observed that there was a high participation rate across weeks. An end-of-course online survey was conducted to explore the learning experiences during formative assessment of the cohort, and students reported high satisfaction with the process, particularly how this contributed to a change in their learning approach. Students not only showed regular commitment of time on tasks but also took active steps to find answers for themselves and with their peers.  相似文献
