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 paper concerns the identification of teaching strategies that enhance the development of 4th grade students’ experimental design skills at a public primary school in Argentina. Students’ performance in the design of relevant experiments was evaluated before and after an eight-week intervention compared to a control group, as well as the persistence of this learning after eight months. The study involved a quasi-experimental longitudinal study with pre-test/post-test/delayed post-test measures, complemented with semi-structured interviews with randomly selected students. Our findings showed improvement in the experimental design skills as well as its sustainability among students working with the inquiry-based sequence. After the intervention, students were able to establish valid comparisons, propose pertinent designs and identify variables that should remain constant. Contrarily, students in the control group showed no improvement and continued to solve the posed problems based on prior beliefs. In summary, this paper shows evidence that implementing inquiry-based units involving problems set in cross-domain everyday situations that combine independent student work with teacher guidance significantly improves the development of scientific skills in real classroom contexts. 相似文献

Counseling services are only likely to be effective if individuals are willing to seek help. Although much of the research on youth help-seeking has focused on adolescents, few studies have examined this in regard to children. Constant comparison analysis of focus group discussions revealed differences based on age and gender. Knowledge, sources of help, willingness, concerns regarding confidentiality, levels of interpersonal openness and stigma tolerance differed based on age. Gender differences were also highlighted. Implications focus on enhancing help-seeking among youth. 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

In this work, the decision-making process involved in the restoration of the eighteenth century paliotto ligneo (wooden altar frontal) della chiesa del Santissimo Crocifisso all’Albergheria of Palermo is presented. Earlier research concerning mirror restoration was based on only a few case studies and the proposed techniques were not suitable for the artwork here. As a consequence, it was necessary to re-examine theories and protocols of modern restoration to plan an appropriate intervention of the altar frontal. Since in this artwork the role of mirrors is not to give back images, as usual, but rather to create special light effects and play of lights, this work aims to find an approach to the restoration of the altar frontal and its decorations that allows a homogeneous overview of the piece. Thus, the mirrors were not substituted or re-created. Only a visual integration of the damaged ancient mirrors was proposed, with the use of metallic-polymeric films, permitting a completely reversible restoration. 相似文献

ABSTRACTOver the last decades privatization policies have taken centre stage in many processes of educational reform globally. In Latin America, these policies have played an important role since the 1990s leading to an increasing participation of private agents in educational provision. The case of Uruguay stands out for having remained somehow apart from this privatization agenda. More recently, however, research has identified a significant shift in the discursive order especially driven by a series of new actors including think tanks and civil society organizations favourable to different forms of privatization. Building on case study methods and informed by a cultural political economy (CPE) approach this paper addresses two purposes. First, it attempts to explore possible explanations for the scarce development of the private sector in Uruguayan education. Second, it aims to characterize the discourses and strategies increasingly used by different actors to frame and promote policy ideas potentially leading to privatization policies. The study shows how a small but influential number of actors have become involved in the process of promoting ideas that seek to influence policymaking. Findings reveal how these actors frame school autonomy and accountability as policy solutions by means of different strategies of networking and knowledge mobilization. 相似文献

ABSTRACT For international organisations in the global education policy field, legitimacy is based in large part on the supposed techno-rational basis of these organisations and their ability to credibly produce knowledge and policy expertise. However, as the present article demonstrates, there are clearly a range of macro–micro organisational dynamics driving the production of knowledge and the policy ideas that are advanced. By revealing the way that a particular policy emerged and was promoted within the World Bank, this article seeks to expose the way that policy innovation is produced by the iterative interplay of agentic activity and particular organisational circumstances – and how this process is used to maintain and extend the influence of international organisations and the individuals who represent them. By drawing on Stewart Clegg’s ‘circuits of power’ approach, we seek to theorise the internal dynamics of international organisations, and, in so doing, to move beyond the dominant coercive and normative perspectives. 相似文献

This paper presents the control solutions to the spacecraft formation reconfiguration problem when impulsive or extended maneuvers are considered, and the reference orbit is circular. The proposed approach for the derivation of the control solutions is based on the inversion of the linearized equations of relative motion parameterized using the mean relative orbit elements. The use of mean relative orbit elements eases the inclusion of perturbing accelerations, such as the Earth’s oblateness effects, and offers an immediate insight into the relative motion geometry. Several maneuvering schemes of practical operational relevance are considered and the performance of the derived impulsive and piecewise continuous control solutions are investigated through the numerical propagation of the nonlinear relative dynamics. Finally, the benefits of the new extended maneuvers strategies are assessed through a comparison with the corresponding impulsive one. 相似文献
