Abstract. Reproducibility and repeatability of experiments are the fundamental prerequisites that allow researchers to validate results and share hydrological knowledge, experience and expertise in the light of global water management problems. Virtual laboratories offer new opportunities to enable these prerequisites since they allow experimenters to share data, tools and pre-defined experimental procedures (i.e. protocols). Here we present the outcomes of a first collaborative numerical experiment undertaken by five different international research groups in a virtual laboratory to address the key issues of reproducibility and repeatability. Moving from the definition of accurate and detailed experimental protocols, a rainfall-runoff model was independently applied to 15 European catchments by the research groups and model results were collectively examined through a web-based discussion. We found that a detailed modelling protocol was crucial to ensure the comparability and reproducibility of the proposed experiment across groups. Our results suggest that sharing comprehensive and precise protocols and running the experiments within a controlled environment (e.g. virtual laboratory) is as fundamental as sharing data and tools for ensuring experiment repeatability and reproducibility across the broad scientific community and thus advancing hydrology in a more coherent way.

The integration of information and communication technology in learning through the application of virtual laboratory media can be an alternative solution to overcome the constraints of time, cost, and laboratory safety in biology labs. Virtual laboratories are very suitable to be applied to the mechanism of evolution because they involve the context of space and time, and can provide opportunities for students to learn independently and increase active student involvement in learning. These study aims are to determine the effect of the application of virtual laboratory media on the understanding of student concepts; knowing increasing students' understanding of the concept of evolutionary mechanisms, and knowing students' responses after learning with virtual laboratories.This type of research is a pre-experimental design (nondesign) with one group pretest-posttest design. The research subjects were 37 students. The media used as many as 8 web-based virtual laboratory programs (online) that can be freely accessed. Data collection techniques include tests (pretest and posttest) and questionnaires. The pretest and posttest values were analyzed by the T-test while the questionnaire data were analyzed descriptively. The application of web-based virtual laboratory media on the evolution mechanism material influences the understanding of student concepts (t arithmetic> t table then H0 is rejected and H1 is accepted) The application of these media increases students' understanding of the concept of evolutionary mechanisms. The mean value increased from pretest 23.65 to 56.08 at the posttest with an increase of 32.43. Student responses to the application of media in learning showed 91.89% of students felt helped in understanding the process of evolution while 100% of students felt helped in understanding the role of evolution in causing evolution.

We discuss possible mechanisms for setting up a global outreach campaign centred on the main theme of this meeting: save our skies! Effective communication of this message to the world's media and the wide public is a prerequisite for successful sensitisation of decision-makers in different countries to the crucial issues at stake. We emphasise the need for careful planning of such a programme, especially in terms of definition of the key issues, the way they are presented, as well as the communication channels to be employed. It is important to differentiate the arguments used in connection with different types of pollution (light, radio, space debris). It will be necessary to identify clear and forceful messages that convincingly stress that these problems are of ultimate concern, not just a small group of astronomers, but to all of humanity. With their extremely sensitive instruments, astronomers constitute an avant-garde that is the first to detect the adverse effects, but as these intensify, increasingly broader sectors of society will be affected. It appears feasible, within the limited means available to the IAU and IDA, to initiate such an outreach effort with a comprehensive web-based campaign that highlights astronomical “pollution”. This may also serve as a useful test-bench for subsequent campaigns based on more communication vehicles and with a wider spectrum of associated activities.

Based on an original definition of modern populism as “democratic illiberalism” and many years of meticulous research, Takis Pappas marshals extraordinary empirical evidence from Argentina, Greece, Peru, Italy, Venezuela, Ecuador, Hungary, the United States, Spain, and Brazil to develop a comprehensive theory about populism. He addresses all key issues in the debate about populism and answers significant questions of great relevance for today’s liberal democracy, including: • What is modern populism and how can it be differentiated from comparable phenomena like nativism and autocracy? • Where in Latin America has populism become most successful? Where in Europe did it emerge first? Why did its rise to power in the United States come so late? • Is Trump a populist and, if so, could he be compared best with Venezuela’s Chávez, France’s Le Pens, or Turkey’s Erdoğan? • Why has populism thrived in post-authoritarian Greece but not in Spain? And why in Argentina and not in Brazil? • Can populism ever succeed without a charismatic leader? If not, what does leadership tell us about how to challenge populism? • Who are “the people” who vote for populist parties, how are these “made” into a group, and what is in their minds? • Is there a “populist blueprint” that all populists use when in power? And what are the long-term consequences of populist rule? • What does the expansion, and possibly solidification, of populism mean for the very nature and future of contemporary democracy? Populism and Liberal Democracy will change the ways the reader understands populism and imagines the prospects of liberal democracy.

Abstract Introduction In 2014, Brännström and colleagues reported the first human live birth following uterine transplantation (UTx). Research into this treatment for absolute uterine factor infertility has since grown with clinical trials currently taking place across centers in at least thirteen countries worldwide. Sources of data This review summarizes and critiques the academic literature on ethical and policy issues raised by UTx. Areas of agreement There is general agreement on the importance of risk reduction and, in principle, to the sharing and maintenance of patient data on an international registry. Areas of controversy There are numerous areas of controversy ranging from whether it is ethically justified to carry out uterus transplants at all (considering the associated health risks) to how deceased donor organs for transplant should be allocated. This review focuses on three key issues: the choice between deceased and living donors, ensuring valid consent to the procedure and access to treatment. Growing points UTx is presently a novel and rare procedure but is likely to become more commonplace in the foreseeable future, given the large number of surgical teams working on it worldwide. Areas timely for developing research Uterus transplantation requires us to re-examine fundamental questions about the ethical and social value of gestation. If eventually extended to transgender women or even to men, it may also require us to reconceptualize what it is to be a ‘father’ or to be a ‘mother’, and the definition of these terms in law.

During the COVID-19 pandemic, schools did not open face-to-face learning services. The Ministry of Education and Culture has issued a policy learning from Home (BDR) to support the principles of the Education Policy in the COVID-19 Pandemic that the health and safety of students, educators, education personnel, families, and the community is the top priority. However, learning in Vocational School (SMK) is mostly based on practice so that BDR activities cannot be implemented. One thing that is done to overcome this is that some practicum activities can be executed using multimedia known as virtual laboratories. The aim of this study is to conduct a need analysis for the development of a virtual laboratory.  Needs analysis is carried out to gather data about gaps and needs as well profiles of students that can be used as a basis or reference in developing virtual laboratory at the next stage. Data collection was carried out by means of observation, interviews, and distributing questionnaires. The results showed that a virtual laboratory was needed to support practical learning for vocational students.

Abstract The KiMoSys (https://kimosys.org), launched in 2014, is a public repository of published experimental data, which contains concentration data of metabolites, protein abundances and flux data. It offers a web-based interface and upload facility to share data, making it accessible in structured formats, while also integrating associated kinetic models related to the data. In addition, it also supplies tools to simplify the construction process of ODE (Ordinary Differential Equations)-based models of metabolic networks. In this release, we present an update of KiMoSys with new data and several new features, including (i) an improved web interface, (ii) a new multi-filter mechanism, (iii) introduction of data visualization tools, (iv) the addition of downloadable data in machine-readable formats, (v) an improved data submission tool, (vi) the integration of a kinetic model simulation environment and (vii) the introduction of a unique persistent identifier system. We believe that this new version will improve its role as a valuable resource for the systems biology community. Database URL:  www.kimosys.org

A presente pesquisa teve como objetivo analisar as representações quantitativas que estão presentes nas interfaces de laboratórios virtuais à luz da Semiótica Peirceana. É uma pesquisa qualitativa exploratória, realizada no repositório portal PhET–Interative Simulation. No percurso da pesquisa foram encontrados 51 aplicativos, desses seis exibiam características de laboratório virtual e três foram semioticamente analisados. Os resultados indicam que três laboratórios apresentam disposições parcialmente satisfatórias nas representações quantitativas que abordam. Esses podem vir a contribuir para o fortalecimento do ensino da Química, por meio de ilustrações, simulações e a participação interativa do estudante. Quanto às possibilidades, esses oferecem diferentes ambientes, formatos e modelos para o estudo desta ciência. Também foram encontradas limitações como a insuficiência de signos iconográficos de ordem quantitativa considerados indispensáveis na conjuntura conceitual de determinados tópicos da Química. As indicações desta pesquisa são para se pensar a respeito dos signos que vão representar a natureza quantitativa da Química, transformando os desafios em possibilidades para os processos de ensino e aprendizagem desta ciência. Palavras-chave: Semiótica. Ensino de Química. Laboratórios Virtuais. Abstract Virtual laboratories used in chemistry teaching are important didactic resources for the advancement of teaching and learning processes, while they can contribute to mediation actions in the knowledge construction. This research aims to analyze the quantitative representations that are present in the virtual laboratories interfaces in light of Peircean semiotics. It is an exploratory qualitative research, conducted at the portal PhET – Interative Simulation. During the research, 51 applications were found, of these, 6 exhibited virtual laboratory characteristics and three were semiotically analyzed. The results indicate that three laboratories have partially satisfactory arrangements in the quantitative representations they address. They can contribute to the strengthening of chemistry teaching through illustrations, simulations and interactive student participation. As for the possibilities they offer different environments, formats and models for the study of this science. Limitations were also found as the insufficiency of quantitative iconographic signs considered indispensable in the conceptual conjuncture of certain topics of chemistry. The indications of this research are to think about the signs that will represent the Chemistry quantitative nature, turning the challenges into possibilities for the teaching and learning processes of this science.

Medical Traditions

In Canada, there is a growing interest in regulating the practices of acupuncture and Chinese herbology under the banner of ‘Traditional Chinese Medicine’ (TCM). However, the origins and definition of TCM are unclear and therefore disputed. While TCM is often used as an umbrella term to represent Chinese medical traditions that span millennia, numerous academics consider TCM to be a modern construct that has departed from the foundational roots of Chinese medicine. To better understand TCM and its implications for the profession, our study investigates: 1) historical precedents leading up to the formal creation of TCM; 2) characteristics and defining features of TCM; and 3) how this relates to education, practice and regulation of the profession in Canada. A mixed-methods study design was employed. Semi-structured interviews were conducted to explore perceptions of individuals who contributed to mediums that discussed the formation of TCM or traditions that exist outside of TCM. In addition, an anonymous web-based survey was sent to TCM-related professional organizations, who were asked to distribute the survey to their members to capture the views of persons practicing within TCM-related health professions in Canada. Due to a lack of participation from the organizations, no survey data was collected. Interviews revealed that TCM is a product of the standardization and simplification of Chinese medicine during the 1950’s and 60’s in China to meet healthcare needs at the time. Currently in Canada, there appears to be a lack of awareness that the establishment of TCM is not a comprehensive representation of Chinese medical traditions, and that many aspects of it may not be suited to the healthcare landscape of modern-day Canada. There is a need for more discussion surrounding the identity of this new profession.

New Research

In recent years medical education has developed dramatically, but lecturers often cite the existence of a gap between theoretical and practical knowledge. In the first decade of the present century, new research methodology named “design-based research (DBR)” was developed, which most experts and journals refer to as a fundamental way to make changes in the quality and applicability of studies and educational research as well as to enhance and improve the practice of instruction. The aim of the present study was introducing design-based research and its concepts, features, applications, and challenges. A narrative review was conducted in 2018. For this purpose, authorized English academic database including Web of Science, Science Direct, Google Scholar, international database and library in medical research filed with keywords including “design-based research, definition of DBR, DBR applications, medical education, and DBR challenges” without date limitation until 2018.11.21 were screened. Overall, 68 articles were selected and after careful reading, 21 article with related subjects were selected for material extraction. The conclusion was made that DBR that combines empirical research with design-based theories could be considered as an effective method for understanding quality, time and the cause of the phenomenon of educational innovation in practice. Usually DBR is formed by initial evaluation of a problem that occurs in a particular context, and this assessment continues throughout design and implementation. One of the characteristics of DBR is the guiding team, which includes researchers, professionals, designers, managers, teachers, trainers and others whose expertise and knowledge may in some way help. The application of DBR in web-based training programs is quite evident. The probability of non-returns in short-term projects is one of the main challenges of DBR. Medical education has developed dramatically in recent years, but it has made little progress in promoting innovative research methodologies. DBR can be used as a bridge between theories and practice and provide the basis for close communication between researchers, designers, and participants. By applying sophisticated methods and multiple sources of information, the success rate of an intervention in a particular environment is assessed, which ultimately leads to improved theories.
