At the end of 2019, the Covid-19 pandemic spread caused restrictions in business and social spheres. Higher education was also severely affected: universities and medical schools moved online to distance learning and laboratory facilities closed. Questions arise about the long-term effects of this pandemic on anatomical education. In this systematic review, the authors investigated whether or not anatomical educators were able to deliver anatomical knowledge during this pandemic. They also discuss the challenges that anatomical education has faced over the last year. The search strategy was conducted between July 2020 and July 2021. Two hundred and one records were identified, and a total of 79 studies were finally included. How best to deliver anatomy to students remains a moot point. In the last years, the advent of new technologies has raised the question of the possible overcoming of dissection as the main instrument in anatomical education. The Covid-19 pandemic further sharpened the debate. Remote learning enhanced the use of technologies other than cadaveric dissection to teach anatomy. Moreover, from the analyzed records it appears that both from students' perspective as well as teachers' there is a clear tear between those who endorse dissection and those who believe it could be easily overcome or at least integrated by virtual reality and online learning. The authors strongly believe that the best anatomy teaching practice requires the careful adaptation of resources and methods. Nevertheless, they support cadaveric dissection and hope that it will not be replaced entirely as a result of this pandemic. 相似文献

This research analyzes network effects in technology acceptance. The hypothesis is that the size of the user network affects technology acceptance. Even today, empirical measurement of network effects is challenging and there is a lack of experimental evidence. In order to investigate and measure the relationship between network size (number of adopters) and user acceptance, technology acceptance research needs to broaden its scope and approaches. To overcome this limitation we reproduce a particular type of technology acceptance process in a laboratory experiment, controlling for user network size and testing its influence on user perceptions and, ultimately, on acceptance decisions. We measured user perceptions and analyzed the data using consolidated and tested technology acceptance models. The results confirm our hypothesis, showing a significant effect of user network size on user perceptions. Finally, we discuss the theoretical and managerial implications of our approach and findings. 相似文献

This paper focuses on the resource management procedures for a geostationary (GEO) satellite system. The objective of these procedures is the efficient exploitation of the link resources, while assuring the agreed Quality of Service to the traffic entering the satellite network. The main novelties are (i) the integration between Connection Admission Control and Downlink Congestion Control procedures, and (ii) the original adaptation of Kalman filtering theory to cope with these procedures. The proposed solution is validated by simulations. 相似文献

The relationship between innovation and employment is addressed in this article through a model and empirical test at industry level for eight European countries in 1994-2004. We investigate this relationship for manufacturing and services and propose a Revised Pavitt taxonomy (covering both of them) in order to identify specific patterns of technological change and job creation and loss. The contrasting effects of strategies of technological or cost competitiveness are investigated using innovation variables from CIS2 and CIS3. Together with demand, wages and industry dynamics, they account for changes in employees and hours worked. The diversity in these relations across industries is also explored; when the model is applied to each Revised Pavitt class, different mechanisms of technological change and effects on jobs emerge. 相似文献

The objective of this study was to assess the prevalence of illicit drugs use among young adults, in particular elite athletes. This study considers the data obtained from anti-doping analyses performed on nearly 100,000 urine samples from 2000 to 2009 by the World Anti-Doping Agency accredited Italian Anti-Doping Laboratory. The percentage of adverse analytical findings varies on a yearly basis, but it is in the range 1.0-1.8% (not considering atypical findings, such as an altered endogenous steroid profile). Among positive results, there is a high prevalence of stimulants and drugs of abuse. The drug of abuse found most frequently is the tetrahydrocannabinol (cannabis) metabolite, accounting for 0.2-0.4% of the total samples analysed (18% of the positive results). The second most frequently encountered drug is cocaine, as detected from cocaine metabolites, accounting for 0.1% of the total samples analysed (7% of positive results). Other stimulants found included amphetamines, ephedrines, carphedon, modafinil, and anorexic compounds. No amphetamine-like designer drugs were detected. These data are indicative of the widespread prevalence of cocaine and cannabis use among the young adult population. However, due to the particular population studied, it must be considered an underestimation of the phenomenon among elite athletes with respect to the general population. 相似文献

An analytical biomechanical model was developed to establish the relevant properties of the Smith squat exercise, and the main differences from the free barbell squat. The Smith squat may be largely patterned to modulate the distributions of muscle activities and joint loadings. For a given value of the included knee angle (θ(knee)), bending the trunk forward, moving the feet forward in front of the knees, and displacing the weight distribution towards the forefoot emphasizes hip and lumbosacral torques, while also reducing knee torque and compressive tibiofemoral and patellofemoral forces (and vice versa). The tibiofemoral shear force φ(t) displays more complex trends that strongly depend on θ(knee). Notably, for 180° ≥ θ(knee) ≥ 130°, φ(t) and cruciate ligament strain forces can be suppressed by selecting proper pairs of ankle and hip angles. Loading of the posterior cruciate ligament increases (decreases) in the range 180° ≥ θ(knee) ≥ 150° (θ(knee) ≤ 130°) with knee extension, bending the trunk forward, and moving the feet forward in front of the knees. In the range 150° > θ(knee) > 130°, the behaviour changes depending on the foot weight distribution. The conditions for the development of anterior cruciate ligament strain forces are explained. This work enables careful use of the Smith squat in strengthening and rehabilitation programmes. 相似文献

Up to now, the optimization of structural parameters affecting the performance of a bobsleigh has been carried out mainly
on the basis of athletes’ feedback, thus leading to a series of small modifications without univocal guidelines. Even though
on-track tests represent a basic step for the final tuning of the sled, experimentation does not seem to represent an appropriate
tool to objectively determine the influence of such structural parameters on the overall performance. In fact, their effect
can easily be masked by driving errors, changes in the ice surface conditions and temperature thus requiring repeated tests
for achieving statistical evidence. For this reason, numerical analysis, carried out with a 3D model of the bobsled, turns
out to be a privileged instrument to optimize bob design although limitations in the sled model (e.g. ice friction properties
that still have to be fully understood) may affect the obtained results. However, such tool is able to provide useful indications
only if a correct driver model is implemented. This work focuses on the development of a numerical model of a bobsleigh driver
that aims at reproducing the driving behaviour of real-world cup drivers and is basically made up of two steps: the identification
of the trajectory that allows minimizing run time and the determination of the driver’s inputs to exactly follow that trajectory.
For comparison purposes, the simulated driver’s inputs are compared with recorded ones on Cesana Pariol Olympic track. 相似文献
