RESUMEN

Curriculum is the core element of talent cultivation in universities, and its quality directly determines that of the talent cultivation. However, the efficiency of online course resource allocation in universities of China is unacceptable, and the corresponding driving mechanisms are unclear. Based on the data of iCourses platform for a top university (H University) of China, this paper develops the DEA-Malmquist index and Tobit regression model to evaluate the efficiency of university online course resource allocation and explore its main influencing factors. The empirical results indicate that, first of all, humanities and social sciences outperform natural sciences in the resource allocation efficiency of online courses. Compared with non-national premium online courses, the resource investment redundancy of national premium online courses appears relatively lower. Secondly, from the perspective of temporal changes, the total factor productivity of online course resource allocation generally has a downward trend. The innovation effect of technological progress is more significant, while the catch-up effect of technical efficiency is clearly insufficient. Scale efficiency is the main factor hindering its improvement. Finally, in terms of the factors affecting the efficiency of online course resource allocation, teachers' research guidance capability, teaching research skills, and the number of courses offered have significantly positive impact.

RESUMEN

For this CHIMIA special issue on the United Nations Sustainable Development Goals (SDGs) and the coincidental 10th anniversary of the association of Women in Natural Sciences (WiNS) at ETH Zurich, there is no better opportunity to share what we have achieved in the last decade. WiNS was originally founded by female PhD students and PostDocs at the Department of Chemistry and Applied Biosciences (D-CHAB) and has expanded to include three additional departments at ETH Zurich. Join us in celebrating our anniversary, reflecting on what we and other associations with the same mission have done to promote gender equality and reduced inequalities for all. We invite you to reflect on what yet has to be done to enact a systemic change towards achieving equal opportunities for all, rather than simply accommodating the female perspective to Switzerland's predominantly masculine working culture.

RESUMEN

Positive outcomes from undergraduate research experiences (UREs) have resulted in calls to broaden and diversify participation in research. However, we have little understanding of what demographics are reported and considered in the analyses of student outcomes from UREs. Without this information, it is impossible to assess whether participation in UREs has been diversified and how outcomes may vary by participant identity. Through a comprehensive literature search, we systematically identified 147 peer-reviewed research articles on student participation in UREs in the natural sciences, published between 2014 and 2020. We coded each paper to document which student demographic variables are reported and considered in analyses. The majority (88%) of articles on UREs reported at least one demographic variable and 62% incorporate demographics into their analyses, but demographics beyond gender and race/ethnicity were infrequently considered. Articles on independent research apprenticeships included demographics in their analyses more frequently than studies on course-based undergraduate research experiences (CUREs). Trends in reporting and analyzing demographics did not change from 2014 to 2020. Future efforts to collect these data will help assess whether goals to diversify UREs are being met and inform how to design UREs to meet the needs of diverse student groups.

RESUMEN

Approximately a third of all annual greenhouse gas emissions globally are directly or indirectly associated with the food system, and over a half of these are linked to livestock production. In temperate oceanic regions, such as the UK, most meat and dairy is produced in extensive systems based on pasture. There is much interest in the extent to which such grassland may be able to sequester and store more carbon to partially or completely mitigate other greenhouse gas emissions in the system. However, answering this question is difficult due to context-specificity and a complex and sometimes inconsistent evidence base. This paper describes a project that set out to summarize the natural science evidence base relevant to grassland management, grazing livestock and soil carbon storage potential in as policy-neutral terms as possible. It is based on expert appraisal of a systematically assembled evidence base, followed by a wide stakeholders engagement. A series of evidence statements (in the appendix of this paper) are listed and categorized according to the nature of the underlying information, and an annotated bibliography is provided in the electronic supplementary material.

RESUMEN

Human societies are complex systems and as such have tipping points. They can rapidly transit from one mode of operation to another and thereby change the way they function as a whole. Such transitions appear as financial or economic crises, rapid swings in collective opinion, political regime shifts, or revolutions. In physics collective transitions are known as phase transitions; for example, water exists in states of liquid, ice, and vapor. A few variables determine which state is realized: temperature, pressure, and volume. For social systems it is less clear what determines collective social states. A better understanding of social tipping points would allow us to tackle some of the big challenges more systematically, such as polarization, loss of social cohesion, fragmentation, or the green transition. The physics concept of universality might be key to understanding some tipping points in human societies and why agent-based models (ABMs) might make sense for identifying the transition points. If universality exists in social systems there is hope that relatively simple ABMs will be sufficient for understanding collective social systems in transition; if it does not exist, highly detailed computational models will be unavoidable. Both are possible. Both need new forms of collaboration between the social and natural sciences, and new types of data will be essential.

RESUMEN

OBJECTIVES: This study aimed to analyze research projects on lung transplant funded by the National Natural Science Foundation of China from 1986 to 2022 and to provide a scientific reference for lung transplant research. MATERIALS AND METHODS: We identified research hotspots and frontiers in the field of lung transplant research using CiteSpace visualization. RESULTS: From 1986 to 2022, the National Natural Science Foundation of China funded 93 projects related to lung transplant, with an average of 2.51 projects and ¥0.94 million annually. The National Natural Science Foundation of China funded 30 institutions across 20 provinces, with general and youth science foundation projects comprising 45.16% and 41.93% of the total projects, respectively. The main categories of disciplines included H0113 respiratory intervention, tracheal reconstruction, and lung transplantation; H1105 organ transplantation and transplant immunization; and H0109 acute lung injury and acute respiratory distress syndrome. The research hotspots mainly included ischemia-reperfusion injury, gene regulation, obliterative bronchiolitis, rejection reaction, T cells, and stem cells. The 6 main research clusters were ischemia-reperfusion injury, immune tolerance, obliterative bronchiolitis, stem cells, pulmonary fibrosis, and rejection reaction. The main key word bursts in the past 5 years were "vein endothelial" and "ex vivo lung perfusion." CONCLUSIONS: In the past 37 years, National Natural Science Foundation of China-funded projects have significantly advanced the clinical application and basic research of lung transplantation. However, compared with developed countries and other solidorgan transplantations, several problems still require attention and improvements in lung transplant research in China.

RESUMEN

Introducción: El aprovechamiento de los cursos de ciencias básicas puede depender de las percepciones estudiantiles sobre la importancia de estos en su vida profesional, por lo que se hace necesario determinar el grado de importancia que los estudiantes le confieren a este tipo de cursos. Materiales y métodos: Se presentó un cuestionario con 9 declaraciones a 54 estudiantes de odontología y medicina. Las respuestas se pasaron a una escala numérica para su análisis. Se usó una prueba de U de Mann-Whitney con el fin de evaluar diferencias entre estudiantes de ambas facultades. Resultados: Los estudiantes en conjunto mostraron tener una buena opinión de la importancia de las ciencias básicas en la práctica clínica. Se observó también que es mayor la proporción de estudiantes de odontología que consideran que la investigación básica no es útil para su práctica clínica. Conclusión: Los estudiantes consideran las ciencias básicas necesarias para un buen desempeño profesional.


Introduction: The benefit of basic science courses may depend on students' perceptions of the importance of these courses in their professional life, therefore, it's necessary to determine the degree of importance that students give to this type of courses. Materials and methods: A questionnaire with 9 statements was presented to 54 dental and medical students. The responses were converted to a numerical scale for analysis. Using a Mann-Whitney U test, differences between students from both faculties were evaluated. Results: The students showed a good opinion of the importance of basic sciences in clinical practice. It was also observed that the proportion of dental students who consider that basic research is not useful for their clinical practice is higher. Conclusion: Students consider the basic sciences necessary for good professional performance.

RESUMEN

In October 2019, an integrated dentistry program (iMED DENT) was implemented at the University of Hamburg and was the first of its kind in Germany. This model curriculum builds on didactic concepts that have been applied successfully for many years in curricula for human medicine, including interdisciplinary teaching, early clinical experience, and scientific education. The first year focuses on the healthy situation ("normal function") and aims to integrate the natural sciences (biology, chemistry, physics) and the basic medical subjects (anatomy, biochemistry, physiology, medical terminology) in the context of dental health. Further, basic practical and clinical tasks are assigned to the students during the first year.From the experience of the first four cohorts, initial conclusions can be drawn about this stage of study. Generally, its modular structure results in a condensation of learning content, which students judge as demanding. However, its interdisciplinary approach is well accepted. For instance, presenting the basics of the natural sciences in the context of their dental relevance is much better evaluated in the new compared to the previous curriculum, in which this content was taught without specific references to dental health. Teaching the basics of medicine within clinical context and the inclusion of early clinical practice are similarly appreciated. Presently, the interdisciplinary approach is limited by the focus on practical competencies of the dentistry curriculum, as some practical courses offer only few opportunities for other disciplines to interconnect their teaching. The continuous evaluation of the curriculum and exchange of experiences between the disciplines will further improve the integrative concept of the curriculum.

RESUMEN

Objective: Based on the application and funding status of National Natural Science Foundation of China (NSFC) in the field of oral and craniofacial sciences (H15), we analyzed the current status of basic research of the Oral and Craniofacial Sciences (OCS) in China, and provided the references for the sustainable and efficient funding of basic research and scientific frontier exploration in the field, supporting the construction of talents and teams, and enhancing the development of OCS in China. Methods: The data of both applied and funded grants of H15 in NSFC from 2010 to 2021 were analyzed, including the number of applications and funding, the amount of funding, the funding rate, the research direction and the supporting units. The status of basic research of H15 was summarized. Results: From 2010 to 2021, H15 received 15 060 applications and funded 2 569 grants. The overall funding rate of H15 was 17.06%, and the total funding amount was 1 140.305 million yuan. The applications and funded projects of H15 were mainly focused on the General Projects and Youth Science Fund Projects, accounting for 90.33% (13 604/15 060) and 88.71% (2 279/2 569) of the total number of applications and funded projects, and 78.05% (89 002.5/114 030.5) of the total funding amount. In terms of talent training, the National Science Foundation for Distinguished Young Scholars received 65 applications, and 6 were founded, with a funding rate of 9.23%. The National Science Foundation for Outstanding Young Scholars received 85 applications, and 13 were founded, with a funding rate of 15.29%. In recent years, the number of applications has gradually increased and the number of grants has remained relatively stable. Among the nine sub-categories of H15, the top three in terms of the number of applications and grants were H1502, H1504, and H1507. H1502 (repair and regeneration of oral and craniofacial tissue and organ defects) received 2 760 applications, and 510 were funded. H1504 (periodontal and oral mucosal diseases) received 2 475 applications, and 419 were funded. H1507 (restoration of tooth defects and loss, and correction of dental deformities) received 2 270 applications, and 367 were funded. Peking University and Sichuan University ranked first and second with 1 092 and 1 001 applications, respectively. The top five recipients were Sichuan University (327 items), Peking University (260 items), Wuhan University (204 items), Shanghai Jiao Tong University (198 items) and the Fourth Military Medical University of the People's Liberation Army (193 items). The funding rates were 32.67%, 23.81%, 23.02%, 21.69% and 29.11%, respectively. Conclusions: Under the support of NSFC, the basic research of oral and craniofacial sciences has been developed in an all-round way. In recent years, the talent training of all echelons has increased year by year, the research direction and geographical coverage is comprehensive, and project support organization has its own research focus and discipline advantages, making contributions to the realization of the goal of healthy China and the progress of world medicine.

RESUMEN

El manuscrito hace una revisión sobre la historia de la Academia de Los Linceanos creada a principios de siglo XVII con todas las vicisitudes que rodearon una existencia la cual ya supera los 500 años. Como una muestra cabal de sus claroscuros se efectúa un repaso de las peripecias atravesadas en los años del fascismo, la política antisemita que la atravesó y la posterior reconstitución concluida la guerra. Vayan pues para ella, los deseos de una travesía en plena armonía y no más sobresaltos. (AU)


The manuscript reviews the history of the Academy of the Linceans created at the beginning of the 17th century with all its ups and downs surrounding an existence that already exceeds 500 years. As a clear example of such chiaroscuro, an account of the threats experienced during the fascist period together with its piercing anti-Semitic policy, and the subsequent reconstitution after the war, is also made. Long live then to the Academy, and our very best wishes for a consonant future devoid of upsetting facts. (AU)

RESUMEN

INTRODUCTION: This study analyzes heart transplantation funding provided by the National Natural Science Foundation of China (NSFC) between 1986 and 2022. The findings offer an objective and scientific reference for heart transplantation research. METHODS: CiteSpace visualization was used to present keywords in heart transplantation research. RESULTS: From 1986 to 2022, the NFSC disbursed ¥117.68 million to fund 259 projects related to heart transplantation. Hubei, Shanghai, Beijing, Guangdong, and Heilongjiang received the most funding. General and youth science fund projects accounted for 58.69% and 30.50%, respectively. The main discipline category was organ transplantation and transplantation immunity, accounting for 40.93%. Research hotspots included "immune tolerance," "rejection reaction," "t cell" "dendritic cell," "stem cell," and "transplantation tolerance." Research foci were "rejection reaction," "heart failure," "immune tolerance," "heart transplantation," "stem cell," "suppressor cell," "dendritic cell," "dilated cardiomyopathy," and "t cell." In the past 5 years, the research frontier has targeted "transplantation tolerance," "ischemia-reperfusion injury," and "heart transplantation." CONCLUSION: Continuous NSFC funding for heart transplantation research has promoted the development of disciplines and cultivation of talent. Novel technologies (e.g., artificial hearts and donor maintenance) have generated new requirements for heart transplantation research.

RESUMEN

Powell and Mannion's recent editorial discusses how different 'models' of the policy process have been applied within the health policy field. They present two ways forward for scholarship: more 'home grown' development of health-specific models, or deeper engagement with broader public policy scholarship. In this paper I argue for the latter approach for several reasons. First, health policy analysis is a social, not a natural science - and as such is not exceptional to other forms of policy scholarship. Second, many 'health policy models' are often grounded in conceptual work from elsewhere (or may not be health specific). Finally, there has been significant work to develop more nuanced understandings of theories, models, and frameworks available to particular analytical tasks and questions. As such, the growing body of global health policy scholarship may find it can benefit more from deeper engagement with existing conceptual work than constructing its own new models in most cases.

RESUMEN

Objective To understand the current status of Chinese medical researchers' knowledge regarding the ethical norms of the research involving humans or laboratory animals,and provide reference for further improving the ethics review norms. Methods The questionnaire method was employed to survey the applicants for the 2019 projects supported by the Department of Medical Sciences,National Natural Science Foundation of China (NSFC) about their knowledge of ethical requirements.Furthermore,the ethical supervision of the NSFC and affiliations at the project application and implementation stages was analyzed. Results The survey showed that 29.9% medical researchers were familiar with NSFC's ethical requirements for research involving human or laboratory animals.During the project application stage,59.0% affiliations adopted the simplified review method.Regarding the ethical supervison,95.5% medical researchers believed that the affiliations should fulfill the ethical supervision obligations and take relevant measures during the project implementation period.In addition,55.0% medical researchers fully agreed to discuss with the review experts about the ethical issues involved in the project. Conclusions The NSFC should establish rules and regulations to improve institutional management responsibilities and institutionalize the training about research ethics to comprehensively strengthening the training.Taking the management of research project ethics as a starting point,the NSFC should form a multi-party linkage between project funding and management and establish an accountability mechanism for ethics management.Furthermore,the NSFC should double the endeavors at the review of ethical issues during expert review and process management and attach importance to the research,judgment,and prevention of ethical risks.

RESUMEN

OBJECTIVE: The National Natural Science Foundation of China (NSFC) has made great progress in promoting the development of aortic dissection research in recent years. This study aimed to examine the development and research status of aortic dissection research in China so as to provide references for future research. METHODS: The NSFC projects data from 2008 to 2019 were collected from the Internet-based Science Information System and other websites utilized as search engines. The publications and citations were retrieved by Google Scholar, and the impact factors were checked by the InCite Journal Citation Reports database. The investigator's degree and department were identified from the institutional faculty profiles. RESULTS: A total of 250 grant funds totaling 124.3 million Yuan and resulting in 747 publications were analyzed. The funds in economically developed and densely populated areas were more than those in underdeveloped and sparsely populated areas. There was no significant difference in the amount of funding per grant between different departments' investigators. However, the funding output ratios of the grants for cardiologists were higher than those for basic science investigators. The amount of funding for clinical researchers and basic scientific researchers in aortic dissection was also similar. Clinical researchers were better in terms of the funding output ratio. CONCLUSION: These results suggest that the medical and scientific research level of aortic dissection in China has been greatly improved. However, there are still some problems that urgently need to be solved, such as the unreasonable regional allocation of medical and scientific research resources, and the slow transition from basic science to clinical practice.

RESUMEN

Over several months, representatives from the U.S. Department of Energy (DOE) Office of Science and National Institutes of Health (NIH) had a number of meetings that lead to the conclusion that innovations in the Nation's health care could be realized by more directed interactions between NIH and DOE. It became clear that the expertise amassed and instrumentation advances developed at the DOE physical science laboratories to enable cutting-edge research in particle physics could also feed innovation in medical healthcare. To meet their scientific mission, the DOE laboratories created advances in such technologies as particle beam generation, radioisotope production, high-energy particle detection and imaging, superconducting particle accelerators, superconducting magnets, cryogenics, high-speed electronics, artificial intelligence, and big data. To move forward, NIH and DOE initiated the process of convening a joint workshop which occurred on July 12th and 13th, 2021. This Special Report presents a summary of the findings of the collaborative workshop and introduces the goals of the next one.
